Description

A new type of infant stroller

technical field

The utility model relates to infant products, in particular to a novel infant stroller.

Background technique

Infant strollers are used to carry infants to reduce the burden of parents holding infants. Infant strollers generally include a foldable frame and a frame locking mechanism that locks the frame in an unfolded state. When pushing the stroller, the infant stroller can be folded, which is convenient to carry, and can reduce the storage volume, thereby occupying less space. The frame is generally composed of a plurality of connecting rods, so that after the frame locking mechanism is released, the connecting rods can be retracted in conjunction with each other. Different connecting rod structures will result in different retractable volumes of the frame. It is relatively large, so that it needs to occupy a large storage space.

In this embodiment, the driver locking mechanism is a known technology and is not the key point of the present invention, so it will not be repeated here.

In this embodiment, the driver's lower 1032 is fixedly connected with the sliding sleeve 105 .

When folding the vehicle frame 1, first release the lock mechanism for the driver, and then rotate the upper driver 1031 forward, so that the upper driver 1031 and the lower driver 1032 are close together; The steel wire 42 pulls the active part 44 upwards, and under the joint action of the oblique long hole 441 and the long hole 431, the block 45 is pulled to move to the inside of the driver's lower 1032, thereby breaking away from the space between the two inner cavities of the pair of sleeves 106 or the front foot. 101 is engaged, the driver's lower 1032 and the front foot 101 can slide relatively, and the frame 1 is released. At this time, the lower driver's 1032 is pushed forward and downward, and the sliding sleeve 105 and the driver's lower 1032 slide down along the front foot 101 to drive the rear foot The upper end of 102 rotates forward and downward, and the rotation of the rear foot 102 will simultaneously link the first connecting rod 104 to pull the driver's lower 1032 and the rear foot 102 close, until finally the driver's upper 1031, the driver's lower 1032, the front foot 101, the rear foot 102 and the first connecting rod. The rods 104 are stacked up and down together, and the vehicle frame 1 is completely folded, so that the volume of the vehicle frame 1 after being folded is very small. In addition, when the sliding sleeve 105 slides down along the front foot 101 , the abutting member 1051 on the sliding sleeve 105 will push the connecting portion 108 to rotate backward around the first connecting rod 8 , and in the linkage of the second connecting rod 107 Next, the stopper 7 is folded together with the vehicle frame 1, that is, after the vehicle frame 1 is completely folded, the connection part 108, the stopper 7, and the second connecting rod 107 will be connected with the upper 1031 of the rider, the lower 1032 of the rider, and the front foot. 101, the rear foot 102, and the first connecting rod 104 are close together, and there is no need to remove the blocking member 7 before folding the frame 1 as in the traditional design, thereby further reducing the volume of the frame 1, and reducing the operation steps, which is greatly convenient to use By.

Unlocking the driver's locking mechanism can also be operated after releasing the vehicle frame locking mechanism 4, that is, the rotation operation of the driver's upper 1031 and the driver's lower 1032 can be performed after other components of the vehicle frame 1 are folded.

In this embodiment, preferably, the outer side of the sleeve 106 of the bracket 10 on one side is provided with a protrusion 1061, and the upper end of the rider lower 1032 on the corresponding side is fixedly connected with an elastic retractable hook 1062, and the upper end of the elastic retractable hook 1062 A locking hole 1063 for fastening the protrusion 1061 is provided. After the frame 1 is folded, the locking hole 1063 of the elastic retractable hook 1062 engages with the protrusion 1061, thereby locking the frame 1 in the folded state, and preventing the folded frame 1 from unfolding during moving .

Preferably, the upper ends of the driver's top 1031 of the two side brackets 10 are respectively connected to the left and right ends of a first cross bar 1034. One piece.

The lower parts of the rear legs 102 of the two side supports 10 are respectively connected to the left and right ends of a second cross bar 1022 , and the lower parts of the front legs 101 of the two side supports 10 are respectively connected to the left and right ends of a third cross bar 1012 .

The cross bars are connected to the brackets 10 on the left and right sides, so that the entire vehicle frame 1 is more stable.

In this embodiment, the infant stroller is provided with two front wheel sets 2 and two rear wheel sets 3, and the two front wheel sets 2 are respectively arranged at the lower ends of the front legs 101 of the brackets 10 on both sides. The rear wheel sets 3 are respectively arranged at the lower ends of the rear feet 102 of the brackets 10 on both sides.

In another embodiment, as shown in Figures 10 and 11, the driver's lower 1032 is relatively slidably connected to the sliding sleeve 105, and a stopper 1033 is fixedly connected to the lower end of the driver's lower 1032. When the frame is unfolded, The stopper 1033 resists the lower end of the sliding sleeve 105 to limit the sliding of the sliding block 105 . When the vehicle frame is folded, after the vehicle frame locking mechanism 4 is released, when the driver's lower 1032 slides down, the stopper 1033 at the lower end will no longer block the sliding sleeve 105, so that the sliding sleeve 105 will also go down along the front foot 101 Moving, driving the upper end of the rear foot 102 to rotate forward and downward until the vehicle frame 1 is completely folded, so that the volume of the vehicle frame 1 after folding is also very small. And when the vehicle frame 1 is to be launched, the driver's bottom 1032 is pulled up, and the block 1033 will drive the sliding sleeve 105 to slide upwards along the front foot 101 until the vehicle frame 1 is fully expanded, and the vehicle frame locking mechanism 4 is re-locked.

In the above orientation description, the location of the front wheel set 2 is the front, the location of the rear wheel set 3 is the rear, the location of the driver 103 is the top, the location of the front and rear wheel sets 2 and 3 is the bottom, and the location of the vehicle frame 1 on both sides is the left and right. Between the side brackets 10 is the inner side.
