Detailed Description
The technical scheme provided by the invention is described in more detail below with reference to fig. 1-17 d.
Referring to fig. 1 to 7b, an embodiment of the present invention provides a stroller frame, which includes a frame body 1, a pedal assembly 2, and a locking mechanism 3. The frame body 1 is configured to have a folded state and an unfolded state. Referring to fig. 1, a pedal assembly 2 is rotatably mounted to a frame body 1. The locking mechanism 3 comprises a locking mechanism 31 and an unlocking mechanism 32, see fig. 9a. A locking mechanism 31 and an unlocking mechanism 32 are provided between the frame body 1 and the pedal assembly 2. The lock mechanism 31 is configured such that the pedal assembly 2 is in the following locked state with respect to the frame body 1, and the unlock mechanism 32 is configured such that the pedal assembly 2 is in the unlocked state with respect to the frame body 1.
Referring to fig. 8, in some embodiments, the stroller frame further includes a driving member 5, where the driving member 5 is disposed between the frame body 1 and the pedal assembly 2, and the driving member 5 is configured to drive the pedal assembly 2 to retract with the frame body 1 when the pedal assembly 2 is in the unlocked state.
The frame body 1 may have an existing structure. In order to facilitate the description of the technical solutions of the embodiments, the following describes some specific implementation manners of the frame body 1.
Referring to fig. 1-4, in some embodiments, the frame body 1 includes a front foot group 100, a seat frame group 200, a handlebar group 300, and a rear foot group 400. The front leg unit 100 is pivotally connected to the rear leg unit 400 to form a first pivot a. The handle set 300 is pivotally connected to the rear leg set 400 to form a second pivot B. Saddle assembly 200 is mounted to forefoot assembly 100 and rearfoot assembly 400. The pivot axis of the hook mounting base 101 and the seat frame set 200 described later is a third pivot axis C. The pivot axis of the forefoot tube joint 11 of the forefoot set 100 and the saddle set 200 is also the third pivot axis C.
Referring to fig. 2, 5 and 6a to 6d, folding of the frame body 1 is controlled by a folding mechanism 10. The folding mechanism 10 comprises a hook mounting seat 101, a fixed pipe 102, a fixed rod 103, a two-way lock hook 104, a pull ring 105, a frame unlocking piece 106 and an elastic reset piece 107. The hook mounting seat 101 is rotatably mounted on the seat frame set 200 of the frame body 1. The hook mount 101 includes two, and one hook mount 101 is mounted on each side of the frame body 1 in the width direction. The two clamping hook mounting seats 101 are fixed with the fixed pipe 102 through pin shafts. That is, if the fixed tube 102 rotates, the catch mount 101 rotates together with the fixed tube 102. The fixing rod 103 is fixed with the seat frame set 200, and the fixing rod 103 is not rotatable. The fixing rod 103 and the fixing tube 102 are located on the same side of the hook mounting seat 101 as the third pivot C of the seat frame set 200, see fig. 7a and 7b, so that when the fixing tube 102 rotates, the hook fixing seat is driven to rotate in a direction away from the fixing rod 103.
The two-way lock hook 104 has a first slot 104d, and the hook mount 101 has a second slot 101a. The opening directions of the first clamping groove 104d and the second clamping groove 101a are opposite, so that the first clamping groove 104d and the second clamping groove 101a can be matched to hold the fixing rod 103. When the first clamping groove 104d and the second clamping groove 101a are clamped tightly together to the fixing rod 103, the frame body 1 is in a locking state. When both the first and second locking grooves 104d and 101a release the fixing lever 103, the frame body 1 is in an unlocked state.
Referring to fig. 5 to 6d, the connection of the two locking hooks 104 to the fixed tube 102 is described below. The two-way lock hook 104 is provided with a first hole 104a for mounting the fixed pipe 102 and a second hole 104b communicating with the first hole 104a. The second hole 104b is perpendicular to the axial direction of the first hole 104a. The fixing tube 102 passes through the first hole 104a. The wall of the portion of the fixing tube 102 located inside the first hole 104a is provided with a locking hole 102b. The locking hole 102b is perpendicular to the center hole 102a of the fixed tube 102. A middle portion of the frame release member 106 is located in the second aperture 104b, and a first end of the frame release member 106 may extend into the center aperture 102a via the locking aperture 102b. If the first end of the frame unlocking member 106 extends into the center hole 102a, the frame unlocking member 106 is in a locked state. In the locked state, the secondary locking hooks 104 and the fixed tube 102 are secured together. If the first end of the frame unlocking member 106 does not extend into the center hole 102a, the frame unlocking member 106 is in an unlocked state. In the locked state, the two locking hooks 104 may be rotated at an angle relative to the fixed tube 102. When the rotation angle of the two-way locking hook 104 relative to the fixed tube 102 does not exceed the limit, rotation of the two-way locking hook 104 does not cause rotation of the fixed tube 102. If the rotation of the two locking hooks 104 exceeds the above-mentioned limit, the rotation of the two locking hooks 104 causes the stationary tube 102 to rotate together, as will be described in detail later.
With continued reference to fig. 5-6 d, the frame release member 106 is provided with a first annular member 106a projecting outwardly from the first end. The end of the second hole 104b remote from the first hole 104a is provided with a second annular member 104c protruding toward the inside of the hole. An elastic restoring member 107 is interposed between the first ring member 106a and the second ring member 104c. The elastic restoring member 107 may be a compression spring. The second end of the frame unlocking member 106 is located outside the second hole 104b, and the tab 105 is fixed with the second end of the frame unlocking member 106.
Referring to fig. 5, or fig. 6a to 6d, detailed procedures of locking and unlocking the secondary lock hook 104 and the fixing tube 102, locking and unlocking the secondary lock hook 104 and the fixing rod 103, and locking and unlocking the hook mount 101 and the fixing rod 103 will be described.
Pulling the pull ring 105 outwards compresses the elastic restoring member 107, and the pull ring 105 drives the frame unlocking member 106 to slide along the inner wall of the second hole 104b, so that the first end of the pull ring 105 is disengaged from the locking hole 102b of the fixing tube 102. This releases the lock between the secondary locking hook 104 and the fixed tube 102.
Continuing to pull the pull ring 105 upwards, the pull ring 105 drives the pedal release lock pin 321 and the two lock seat hooks to rotate around the fixed pipe 102 together, so that the first clamping groove 104d of the two lock hooks 104 leaves the fixed rod 103 to unlock the two lock seat hooks and the fixed rod 103.
The rotation of the two locking hooks 104 corresponding to the fixed tube 102 is in an angular range, and when the two locking hooks 104 corresponding to the fixed tube 102 rotate to the limit position (limited by the limiting piece 6, see fig. 6 d), the pull ring 105 is pulled continuously, which causes the two locking hooks 104 to drive the fixed tube 102 to rotate together. Since the fixing tube 102 is fixedly connected with the hook mounting seat 101, the rotation of the fixing tube 102 drives the hook mounting seat 101 to rotate together. As described above, since the positions of the hook mount 101 and the third pivot axis C of the seat frame set 200 are such that the fixing lever 103 and the fixing tube 102 are located on the same side of the hook mount 101 and the third pivot axis C of the seat frame set 200, pulling the pull ring 105 upward causes the hook mount 101 to rotate upward, so that the second clamping groove 101a of the hook mount 101 is away from the fixing lever 103. At this point, the frame body 1 is unlocked at the first pivot C, and the frame body 1 can be retracted by pulling the retraction wire rope 6, see fig. 2.
During the folding process of the frame body 1, the pivot points of the front foot set 100, the seat frame set 200, the handle set 300 and the rear foot set 400 are all rotated. The cover 12 is a member provided between the front leg unit 100 and the handle unit 300. The cover 12 has two pivot axes, one being a first pivot axis a and the other being a second pivot axis B, see fig. 2. The cover 12 is fixed to the rear leg 400 and is not rotatable, and the handle set 300/front leg set 100 is rotatably coupled to the cover 12 to form a first pivot axis a and a second pivot axis B, respectively. During the frame folding process, the cover 12 does not rotate, and the front leg assembly 100 on the cover 12 rotates about the first pivot axis a. How to unlock the pedal assembly 2 and then fold the frame body 1 together will be described later. Before describing this, a specific implementation manner of the pedal assembly 2, the posture adjustment mechanism 4, and a connection manner between the pedal assembly 2 and the frame body 1 will be described.
Referring to fig. 8, in some embodiments, the stroller frame further comprises an attitude adjustment mechanism 4, the attitude adjustment mechanism 4 being disposed between the footrest assembly 2 and the frame body 1, the attitude adjustment mechanism 4 being configured to adjust the attitude of the footrest assembly 2 relative to the frame body 1 in the deployed state.
The respective implementations of the footrest assembly 2, the locking mechanism 3, and the posture adjustment mechanism 4 and the connection relationship are described below.
Referring to fig. 8, the footrest assembly 2 is not a footrest on the front set of feet 100, but rather is a separate bar for an infant to pedal. The pedal assembly 2 comprises a transverse tube 21, a wrench fixing seat 22, a wrench 23 and a bending tube 24. The bent pipe 24 is generally L-shaped, and adopts a square structure formed by two L-shaped pipes and one transverse pipe 21 together so as to facilitate the stepping of the infant. The cross tube 21 is a straight tube, and the cross tube 21 is a rotatable member that can be rotated after unlocking. The unlocking operation of the pedal assembly 2 is realized by two groups of mechanisms, one group is a posture adjusting mechanism 4, and the posture adjusting mechanism 4 can unlock the pedal assembly 2 when the frame body 1 is in an unfolding and locking state, and then manually lift and put down the bent pipe 24 to realize the posture adjustment of the pedal assembly 2. Another set of mechanisms that effect unlocking of the foot pedal assembly 2 is the unlocking mechanism 32 mentioned above. The unlocking mechanism 32 can unlock the pedal assembly 2 together after the frame body 1 is unlocked, and then under the action of the tension spring, the pedal assembly 2 is synchronously folded along with the folding of the frame body 1. The tension spring is arranged between the transverse tube 21 and the frame body 1 and is a driving part 5. These will be described in detail later.
Referring to fig. 9a, 15 and 16, in some embodiments, the drive member 43 of the attitude adjustment mechanism 4 is fixed to the footrest assembly 2 so that the attitude of the footrest assembly 2, i.e., the angle relative to the forefoot set 100, can be conveniently adjusted. To facilitate the installation of the driver 43, the foot pedal assembly 2 further includes the wrench holder 22 and the wrench 23 as described above. The wrench fixing seat 22 is fixedly connected with the two bending pipes 24, and the wrench fixing seat 22 is located between the two bending pipes 24. The wrench 23 is rotatably mounted on the wrench holder 22, and the driving member 43 is connected to the wrench 23, and the driving member 43 described above is driven to move by rotation of the wrench 23 relative to the wrench holder 22. One end of the bending pipe 24 is fixedly connected with a second mounting hole 412 of the pedal joint 41, and the other end of the bending pipe 24 is fixedly connected with the wrench fixing seat 22. The driving element 43 is in particular a rope which is pressed against the wrench holder 22 by means of a press sleeve 45. The press sleeve 45 is fixedly connected with the wrench fixing seat 22 by a cotter pin 46. The end of the string is fixed to the handle 23.
In other embodiments, the end of each elbow 24 remote from the wrench holder 22 is provided with a foot joint 41 as described below.
A specific implementation of the locking mechanism 31 will be described first.
Referring to fig. 9a to 12, the frame body 1 includes a front foot tube joint 11. The locking mechanism 31 includes a first meshing tooth 311 and a locking gear 312. The first engagement teeth 311 are provided on the forefoot tube joint 11, and the lock gear 312 is provided with second engagement teeth 312a. When the first engagement teeth 311 and the second engagement teeth 312a are engaged with each other, the pedal assembly 2 is in a locked state with respect to the frame body 1, and when the first engagement teeth 311 and the second engagement teeth 312a are disengaged, the pedal assembly 2 is in an unlocked state with respect to the frame body 1. The locked state between the pedal assembly 2 and the frame body 1 is unlocked with the unlocking of the frame body 1.
In the above technical solution, the first engagement tooth 311 and the second engagement tooth 312a are separated from the engagement relationship by being separated from each other in the axial direction, and the engagement relationship is formed by being brought close to each other in the axial direction.
Referring to fig. 11, in order to make the second engagement teeth 312a more easily disengaged from the first engagement teeth 311 when they are disengaged, in some embodiments, the end face of the second engagement teeth 312a facing the first engagement teeth 311 is provided with a guide slope 312b.
A specific implementation of the unlocking mechanism 32 is described below.
Referring to fig. 9a to 12, the frame body 1 further includes a cover 12, and the cover 12 is disposed on a side of the front foot pipe joint 11 away from the locking mechanism 3. Referring to fig. 9a and 9b, the unlocking mechanism 32 includes a foot-operated unlocking pin 321 and an unlocking ramp 322. The foot release lock pin 321 is provided on the front foot pipe joint 11 so as to be movable in the axial direction of the foot release lock pin 321, and the foot release lock pin 321 penetrates and protrudes from the front foot pipe joint 11. The cover 12 is provided with an unlocking ramp 322. Wherein, the cover 12 is configured such that the rotation of the front foot group 100 relative to the cover 12 can cause the unlocking inclined plane 322 to abut against the foot release lock pin 321, so that the foot release lock pin 321 moves along the axial direction of the foot release lock pin 321, and the foot release lock pin 321 gradually pushes the second engaging tooth 312a towards the end face of the first engaging tooth 311 during the linear movement of the foot release lock pin 321 relative to the cover 12. Thus, the foot-operated unlocking pin 321 can push the second engagement tooth 312a in a direction away from the first engagement tooth 311, so that the first engagement tooth 311 and the second engagement tooth 312a are disengaged.
Referring to fig. 9a to 14, a specific implementation of the posture adjustment mechanism 4 is described below.
The posture adjusting mechanism 4 is provided on a side of the lock gear 312 remote from the forefoot tube joint 11, and is configured such that the second engagement teeth 312a of the lock gear 312 are disengaged from the first engagement teeth 311.
The posture adjustment mechanism 4 may also disengage/bring the first engagement tooth 311 and the second engagement tooth 312a into engagement. After the first engaging teeth 311 and the second engaging teeth 312a are disengaged by the posture adjusting mechanism 4, the pedal assembly 2 can be rotated relative to the frame body 1 to adjust the posture of the pedal assembly 2, i.e., the angle of the pedal assembly 2 relative to the frame body 1.
The above-described foot joint 41 is a part of the posture adjustment mechanism 4, and the posture adjustment mechanism 4 includes a slide sleeve 42 and a driver 43 in addition to the foot joint 41. Referring to fig. 10, the pedal joint 41 has a first mounting hole 411. Referring to fig. 14a and 14b, the sliding sleeve 42 has a through hole 424 therethrough, and an inner wall of the sliding sleeve 42 is provided with an abutment slope 421. Referring to fig. 11, the end of the locking gear 312 remote from the second engagement tooth 312a is provided with an arc surface 312c protruding toward the outside, an abutment inclined surface 421 is located between the arc surface 312c and the second engagement tooth 312a, the arc surface 312c abuts against the abutment inclined surface 421, and the slide bush 42 is rotatably provided inside the first mounting hole 411. The driving member 43 is coupled to the sliding sleeve 42 to rotate the sliding sleeve 42 relative to the pedal joint 41. Wherein, rotation of the sliding sleeve 42 relative to the pedal joint 41 causes the abutment inclined surface 421 to move axially with the cambered surface 312c, so that the first engaging tooth 311 and the second engaging tooth 312a are disengaged.
Referring to fig. 9a and 16, in some embodiments, the driving member 43 includes a pull cord, the outer surface of the sliding sleeve 42 is provided with a groove 422 along the circumferential direction, one section of the pull cord is located in the groove 422, and one end of the pull cord is fixed to the sliding sleeve 42, and the other end of the pull cord is used as a force application end.
Referring to fig. 14, in some embodiments, the sliding sleeve 42 is provided with relief grooves 423, the relief grooves 423 matching the shape of the cambered surface 312c to avoid interference of the abutment inclined surface 421 and the cambered surface 312c during installation of the cambered surface 312c to the sliding sleeve 42.
Referring to fig. 9a and 14, in other embodiments, the attitude adjustment mechanism 4 further includes a return spring 44 disposed between the sliding sleeve 42 and the second engagement tooth 312a, the return spring 44 being configured to return the sliding sleeve 42.
From the above description, the pedal assembly 2 mainly has the following actions of self posture adjustment and folding along with folding of the frame body 1.
Prior to both actions, the lock between the pedal assembly 2 and the frame body 1 needs to be released. Unlocking is finally achieved by the second engagement tooth 312a being moved away from the first engagement tooth 311, with the difference that the second engagement tooth 312a is carried away from the first engagement tooth 311 by the driving member 43 during its own attitude adjustment. In the process that the pedal assembly 2 is folded along with the folding of the frame body 1, the unlocking inclined surface 121 on the cover body 12 pushes the pedal unlocking pin 321 to abut against the second meshing tooth 312a, so that the second meshing tooth 312a and the first meshing tooth 311 are separated.
Specifically, during the posture adjustment itself, the second engagement teeth 312a and the first engagement teeth 311 are separated from each other in such a manner that the wrench 23 is rotated with respect to the wrench fixing base 22 when the wrench 23 is pulled, and the string (as the driving piece 43) fixedly connected to the wrench 23 is pulled. Since the other end of the rope is secured to the runner 42. When the string is pulled, the sliding sleeve 42 is driven to rotate relative to the pedal joint 41. In the process of rotating the sliding sleeve 42, as the sliding sleeve 42 and the locking gear 312 are matched through the propping inclined plane 421 and the cambered surface 312c, the propping inclined plane 421 of the sliding sleeve 42 pushes the cambered surface 312c to move in a direction away from the first engaging tooth 311, so that the first engaging tooth 311 and the second engaging tooth 312a are disengaged, and the pedal assembly 2 is unlocked relative to the frame body 1. After unlocking, the angle of the pedal assembly 2 relative to the frame body 1 can be manually adjusted up and down, so that the posture of the pedal assembly 2 is adjusted.
In the process of folding the pedal assembly 2 along with folding the frame body 1, the second meshing teeth 312a and the first meshing teeth 311 are separated, namely, the cover 12 rotates along with folding the frame body 1 after the third pivot shaft C is unlocked. During rotation of the front set 100 attached to the cover 12, the unlocking ramp 121 on the cover 12 pushes the foot-rest lock pin 321 against the second engagement tooth 312a to disengage the second engagement tooth 312a from the first engagement tooth 311.
Referring to fig. 17a to 17d, the folding process of the pedal assembly 2 along with the folding of the frame assembly will be described.
As shown in fig. 17a, in the original state, the frame body 1 is in the unfolded state, the frame unlocking member 106 penetrates into the first hole 104a under the independent action of the elastic reset member 107, the two locking hooks 104 are locked, the two locking hooks 104 are clamped on the fixing rod 103, the frame unlocking member 106 is locked, and the frame unlocking member 106 is clamped on the other side of the fixing rod 103, so that the frame body 1 is kept in the unfolded state.
When the frame body 1 needs to be folded, referring to fig. 6a to 7b, by pulling the pull ring 105, the frame unlocking member 106 is separated from the first hole 104a against the force of the elastic restoring member 107 under the action of the pull ring 105, and the two-way locking hook 104 is unlocked, at this time, the two-way locking hook 104 is driven to rotate by lifting up the pull ring 105, the two-way locking hook 104 is separated from the fixing rod 103, and the frame unlocking member 106 is unlocked. At this time, the pull ring 105 is continuously lifted upwards, and then the frame unlocking member 106 is driven to rotate, the frame unlocking member 106 is separated from the fixing rod 103, and the frame unlocking member 106 is in an unlocking state. The frame body 1 can stand after folding, and occupation space is little, and folding stability is high.
The folding process of the frame body 1 around the third pivot axis C is as follows, the unlocking slope 121 on the cover 12 pushes the pedal release pin 321 described above. The pedal release pin 321 pushes the second engagement tooth 312a to move to unlock the pedal assembly 4. The footrest assembly 4 is then pulled by the drive member 5, in particular a tension spring, secured to the seat tube of the seat frame set 200 to pivot the retracting footrest assembly 4.
