Detailed ways

The present application will be described in further detail below in conjunction with accompanying drawings 1-8.

The embodiment of the present application discloses a multi-gear control device for bedding. Referring to FIG. 1 and FIG. 2 , a multi-gear control device for bedding includes a four-bar linkage mechanism 1 , a locking mechanism 2 and a control mechanism 3 . There are two four-bar linkage mechanisms 1 and two locking mechanisms 2 , and one four-bar linkage mechanism 1 corresponds to one locking mechanism 2 . The two four-bar linkages 1 are respectively used to be installed on both sides of the bed back 9 . Referring to, 3, the four-bar linkage mechanism 1 includes a first rod 4, a third rod 6, a second rod 5 and a fourth rod 7 which are sequentially connected to each other in rotation. The first rod 4 is fixedly installed on the bed frame 8 , and the second rod 5 is fixedly installed on the bed back 9 . The control mechanism 3 controls the locking mechanism 2 to lock the four-bar linkage mechanism 1 or unlock the four-bar linkage mechanism 1 .

For the initial state of the four-bar linkage mechanism 1, refer to Fig. 3 and Fig. 4 . When the angle of the bed back 9 needs to be adjusted, the control mechanism 3 controls the locking mechanism 2 to unlock the four-bar linkage 1 so that the four-bar linkage 1 can move. At this time, the bed back 9 can be driven relative to the bed by applying force to the bed back 9 The frame 8 rotates until the backrest 9 of the bed rotates to a suitable angle, and the control mechanism 3 no longer applies force to the locking mechanism 2, so that the locking mechanism 2 returns to the state of locking the four-linkage bar, and the angle of the backrest 9 of the bed is stabilized after manual adjustment. Angle. Realize the adjustment of 9 angles of the backrest of the bed, so as to meet different usage requirements. For the maximum movement angle of the four-bar linkage mechanism 1, refer to Fig. 5 and Fig. 6 .

Specifically, referring to FIG. 7 and FIG. 8 , the locking mechanism 2 includes a shift control lever 10 , a latch 11 , a fixing seat 12 , a rotating member 13 , a push plate 14 and an elastic member. The gear control rod 10 is arranged in an arc shape, and a plurality of sockets 16 are equally spaced on the gear control rod 10 . The first rod 4 is provided with six installation holes 17 at intervals along its length direction, and the gear control rod 10 is provided with two installation nails 18 , and one installation nail 18 is used to be fixedly connected with any one installation hole 17 . The gear control rod 10 is fixedly installed in a proper position relative to the first rod 4 through the mounting nail 18 .

Referring to FIG. 7 and FIG. 8 , the fixing seat 12 is fixedly installed on the third rod 6 . The rotating member 13 includes a rotating base 19 and a mounting base 20 , the rotating base 19 is rotatably connected to the fixed base 12 , the mounting base 20 is fixedly mounted on the rotating base 19 by bolts, and the mounting base 20 is used for connecting the control mechanism 3 . The push plate 14 is fixedly mounted on the rotating member 13 . The pin 11 passes through the push plate 14 and is slidably connected to the push plate 14 . A circlip 21 is installed on the latch 11, and the circlip 21 abuts against the side of the push plate 14 away from the gear adjusting rod. The elastic member is a compression spring 15 , the compression spring 15 is sheathed on the latch 11 , and both ends of the compression spring 15 abut against the third rod 6 and the retaining spring 21 .

The control mechanism 3 drives the rotating member 13 to rotate, so that the push plate 14 pushes the latch 11 away from the jack 16, and now the four-bar linkage mechanism 1 is unlocked, and the bed back 9 can move relative to the bed frame 8. When the control mechanism 3 does not apply force to the rotating member 13, the elastic member drives the latch 11 to be inserted into the socket 16, and the latch 11 will also push the push plate 14 to rotate the rotating member 13 relative to the fixed seat 12 to the initial state. Realize the fixing of the bed back 9 relative to the bed frame 8 . Optionally, a reset member is provided between the rotating member 13 and the fixed seat 12 for keeping the rotating member 13 in an initial state, and the reset member may be a torsion spring. In the initial state, the control mechanism 3 does not apply force to the rotating member 13 .

Referring to FIG. 7 , in order to prevent the control mechanism 3 from exerting force on the rotating member 13 , when the locking mechanism locks the four-bar linkage mechanism 1 , the bolt 11 can be stably inserted into the insertion hole 16 . The second rod 5 and the fourth rod 7 are rotationally connected through a torsion spring return assembly 22 . The torsion spring reset assembly 22 includes a torsion spring and an end cover. The torsion spring is used to drive the second rod 5 and the fourth rod 7 to return to the natural state. The end cap is used to cover the rotational connection points of the torsion spring, the second rod 5 and the fourth rod 7 . Thereby reducing the probability of sundries interfering with the torsion spring.

When the control mechanism 3 no longer exerts force on the rotating member 13, if the pin is not aligned with the insertion hole 16 at this time, the four-bar linkage mechanism 1 cannot be locked. At this time, because the torsion spring return assembly 22 drives the second rod 5 and the fourth rod 7 to rotate, the shape of the entire four-bar linkage mechanism 1 changes, and the pin enters the nearest insertion hole 16 to reach a locked state. Ensure that the backrest 9 of the bed can remain stable relative to the bed frame 8 after the angle is adjusted.

Referring to FIG. 2 and FIG. 7 , the control mechanism 3 includes a connecting base 23 , two pull wires 24 and a force applying member 25 . One pull wire 24 corresponds to one locking mechanism. The connecting seat 23 is fixedly installed in the middle part of the bed frame 8 . One end of the pull wire 24 is fixedly connected to the mounting base 20 by a bolt, and the other end passes through the connecting base 23 .

In this embodiment, the force application member 25 is a pull ring made of cloth tape.

By applying force to the force applying member 25 and transmitting force through the pull wire 24 , the rotating member 13 is pulled to rotate relative to the fixed seat 12 to complete the unlocking of the four-bar linkage mechanism 1 . When no more force is applied to the force applying member 25, both the rotating member 13 and the latch 11 are reset, and the locking of the four-bar linkage mechanism 1 is completed.

Referring to FIG. 5 , in order to prevent the bed back 9 from over-rotating, the gear control rod 10 is provided with a limiting member 26 . The limiting member 26 can be a limiting block, a limiting rivet, etc. In this embodiment, the limiting member 26 is a limiting rivet. When the second rod 5 is parallel to the third rod 6 , the limiting member 26 abuts against the third rod 6 . At this time, the four-bar linkage mechanism 1 cannot continue to move toward the stopper 26, so that the bed back 9 cannot rotate excessively. At the same time, with reference to Fig. 3, when the four-bar linkage mechanism 1 is in the initial state, the stopper 26 abuts against the inner side of the fourth rod 7, and the first rod 4 can no longer move toward the fourth rod 7, so that the bed back 9 Won't overspin.

3. After the bed backrest 9 is adjusted to a suitable angle, release the force applying member 25. At this time, the pull wire 24 no longer exerts force on the rotating member 13. Under the action of the pressure spring 15, the latch 11 moves toward the gear adjustment lever; if the latch 11 is aligned with the socket 16, and the latch 11 is directly inserted into the socket 16 to complete the locking of the four-bar linkage mechanism 1; if the pin is not aligned with the socket 16 at this time, the torsion spring return assembly 22 drives the second rod 5 Rotate with the fourth rod 7, so that the shape of the whole four-bar linkage mechanism 1 changes, and the pin enters the nearest jack 16 to reach the locked state; ensure that the bed back 9 can remain stable relative to the bed frame 8 after the angle is adjusted;

4. The gear-adjustable bed backrest 9 can give users resting postures at different angles and improve the comfort of the large-area support of the back, thereby improving the comfort of use;

5. When it is necessary to adjust the angle difference between the rotation gears of the bed back 9, the gear control lever 10 can be fixed and installed at different positions relative to the first rod 4 through the installation nail 18, and then the angle difference between the two gears can be adjusted. Poor angle.
