Description

Technical Field

[0001] The present application relates to the field of vehicle seats, and in particular, to a rapid descent adjustment device for a vehicle seat. Background Art

[0002] With the development of vehicle technology, vehicle seats are not only satisfied with the function of providing a ride for drivers and passengers, but are developing in the direction of improving the riding comfort of drivers and passengers. Therefore, pneumatic seats that can be adjusted according to the needs of drivers and passengers are increasingly applied to vehicle seats.

[0003] Currently, the pneumatic device of a vehicle seat is usually quickly controlled by a rapid descent valve. The rapid descent button needs to be installed along the telescopic direction of the rapid descent valve. When the driver or passenger presses the rapid descent button, the rapid descent button squeezes the rapid descent valve, causing the pneumatic device to exhaust and achieve rapid descent. At this time, the rapid descent function is turned off; after the rapid descent button is reset, the pneumatic device is inflated and the rapid descent function is restored.

[0004] However, due to the limited structural space of the vehicle seat, the installation method of directly installing the rapid descent button along the telescopic direction of the rapid descent valve will occupy a large space in the telescopic direction of the rapid descent valve, and it is difficult to find a reasonable installation space in the narrow space of the vehicle seat. Utility Model Content

[0005] In order to improve the problem that the rapid descent button is installed along the telescopic direction of the rapid descent valve and occupies a large space in the telescopic direction of the rapid descent valve of the vehicle seat, the present application provides a rapid descent adjustment device for a vehicle seat.

[0006] The rapid descent adjustment device for a vehicle seat provided by the present application adopts the following technical solutions:

[0007] A rapid descent adjustment device for a vehicle seat includes a bracket, a rapid descent button, a rapid descent valve, and a transmission mechanism. The rapid descent button is slidably disposed on the bracket, the rapid descent valve is disposed on the bracket, the rapid descent valve and the rapid descent button are arranged in a staggered manner, and the transmission mechanism is disposed on the bracket and is used to press against the rapid descent valve when the rapid descent button is pressed.

[0008] By adopting the above technical solutions, when the driver or passenger presses the rapid descent button, the rapid descent button drives the transmission mechanism to press against the rapid descent valve, and the rapid descent valve can be started to exhaust to achieve the rapid descent function. Through the transmission of the transmission mechanism, the rapid descent button and the rapid descent valve can be installed in a staggered manner according to the seat space, effectively improving the problem that the rapid descent button is installed along the telescopic direction of the rapid descent valve and occupies a large space in the telescopic direction of the rapid descent valve of the vehicle seat.

[0009] Optionally, the bracket includes a rapid descent base and a protective shell. The protective shell is snapped onto the rapid descent base. The rapid descent button is slidably disposed on the protective shell, and the rapid descent valve is disposed on the rapid descent base.

[0010] By adopting the above technical solution, after the staff install each component on the speed reduction base and the protective shell respectively, and then buckle the protective shell onto the speed reduction base, the assembly can be completed, improving the convenience of assembly.

[0011] Optionally, a plug rod is provided on the protective shell, and a jack for inserting the plug rod is provided on the speed reduction base.

[0012] By adopting the above technical solution, during the process of buckling the protective shell onto the speed reduction base, the plug rod is inserted into the jack to guide the installation of the protective shell, improving the accuracy of buckling the protective shell onto the speed reduction base.

[0013] Optionally, the transmission mechanism includes a speed reduction bracket, a connecting frame and a positioning member. The speed reduction bracket is rotatably arranged on the speed reduction base in the direction towards the speed reduction valve. The connecting frame is hinged to the speed reduction bracket. The connecting frame is hinged to the speed reduction button. The positioning member is arranged on the speed reduction base and is used to position the speed reduction bracket at the position of pressing the speed reduction valve.

[0014] By adopting the above technical solution, when the driver or passenger presses the speed reduction button, the speed reduction button squeezes the connecting frame, and the connecting frame then squeezes the speed reduction bracket, so that the speed reduction bracket rotates towards the direction close to the speed reduction valve and presses on the speed reduction valve, and the speed reduction bracket is positioned at the position of pressing the speed reduction valve through the positioning member, so that the speed reduction valve can be continuously opened for speed reduction.

[0015] Optionally, the positioning member includes a self-locking switch and a clamping block. The self-locking switch is arranged on the speed reduction base, and the clamping block is arranged on the speed reduction bracket. The self-locking switch is used to lock the clamping block when the speed reduction bracket presses on the speed reduction valve and release the lock on the clamping block when the speed reduction button is pressed again.

[0016] By adopting the above technical solution, during the process of the speed reduction bracket rotating towards the direction close to the speed reduction valve, the clamping block is driven to approach the self-locking switch. As the speed reduction bracket continues to move, the clamping block abuts against the self-locking switch, and the self-locking switch locks the clamping block; after the speed reduction button is pressed again, the clamping block is driven to squeeze the self-locking switch again, and the self-locking switch can release the lock on the clamping block.

[0017] Optionally, a spring is arranged on the speed reduction valve, and the spring is used to drive the speed reduction valve to reset.

[0018] By adopting the above technical solution, when the speed reduction bracket presses on the speed reduction valve, the spring is compressed. After the self-locking switch releases the lock on the clamping block, the spring restores its deformation and drives the speed reduction bracket to rotate away from the speed reduction valve for reset. The speed reduction bracket can conveniently drive the speed reduction button to reset through the connecting frame.

[0019] Optionally, a guiding post is provided on the rapid descent button, and a guiding hole for inserting the guiding post is formed on the rapid descent base.

[0020] By adopting the above technical solution, the guiding post guides the pressing and resetting of the rapid descent button, improving the sliding stability of the rapid descent button during the pressing and resetting processes.

[0021] Optionally, an anti - detachment block is provided at one end of the rapid descent button located inside the protective shell, and the anti - detachment block is used to abut against the protective shell when the rapid descent button slides in a direction away from the protective shell.

[0022] By adopting the above technical solution, during the process of the rapid descent button sliding in a direction away from the protective shell to reset, the rapid descent button drives the anti - detachment block to move, and the anti - detachment block can abut against the protective shell to limit the rapid descent button from continuing to slide out of the protective shell in a direction away from the protective shell, reducing the possibility of the rapid descent button sliding out of the protective shell.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The rapid descent button and the rapid descent valve can be misaligned and installed according to the seat space, effectively improving the problem that the rapid descent button installed along the telescopic direction of the rapid descent valve occupies a large space of the vehicle seat in the telescopic direction of the rapid descent valve.

[0025] 2. The clamping block abuts against the self - locking switch, and the self - locking switch locks the clamping block; after the rapid descent button is pressed again, it drives the clamping block to squeeze the self - locking switch again, and the self - locking switch can release the lock on the clamping block.

[0026] 3. After the self - locking switch releases the lock on the clamping block, the spring resumes deformation and drives the rapid descent bracket to rotate in a direction away from the rapid descent valve to reset, and the rapid descent bracket can conveniently drive the rapid descent button to reset through the connecting frame.

Detailed implementation mode

[0032] The following further describes the present application in detail with reference to the Figures 1-4 accompanying drawings.

[0033] An embodiment of the present application discloses a speed reduction adjustment device for an automobile seat.

[0034] Referring to Figure 1 , the speed reduction adjustment device for an automobile seat includes a bracket 1, a speed reduction button 2, a speed reduction valve 3 and a transmission mechanism 4.

[0035] Referring to Figure 1 , Figure 2 , the bracket 1 includes a speed reduction base 11 and a protective housing 12. A plurality of insertion rods 5 are installed on the protective housing 12. A plurality of insertion holes are provided on the speed reduction base 11. One insertion hole corresponds to one insertion rod 5. The protective housing 12 is snap-fitted on the speed reduction base 11.

[0036] With the split structure of the protective housing 12 snap-fitted on the speed reduction base 11, after the staff installs each component on the protective housing 12 and the speed reduction base 11 respectively, the protective housing 12 can be snap-fitted onto the speed reduction base 11 for installation, effectively improving the convenience of the staff's assembly. Moreover, the protective housing 12 and the speed reduction base 11 can also protect each component inside; during the process of the staff snap-fitting the protective housing 12 onto the speed reduction base 11, the plurality of insertion rods 5 are respectively inserted into the plurality of insertion holes one by one, and the side walls of the insertion holes guide the insertion rods 5, effectively improving the accuracy of snap-fitting the protective housing 12 onto the speed reduction base 11.

[0037] Referring to Figure 2 , Figure 3 , the speed reduction button 2 is slidably installed on the protective housing 12. A plurality of guide posts 7 are installed on the speed reduction button 2. A plurality of guide holes are provided on the speed reduction base 11. The plurality of guide posts 7 are respectively slidably inserted into the plurality of guide holes one by one; and an anti-disengagement block 8 is circumferentially installed on the speed reduction button 2, and the diameter of the anti-disengagement block 8 is greater than the diameter of the opening of the speed reduction button 2 sliding on the protective housing 12.

[0038] When the driver or passenger presses the rapid descent button 2, the rapid descent button 2 drives the guide post 7 to move. The side wall of the guide hole guides the guide post 7, effectively improving the sliding stability of the rapid descent button 2 during the process of being pressed and moving or resetting; and when the rapid descent button 2 moves away from the rapid descent base 11 and resets, the rapid descent button 2 drives the anti - detachment block 8 to move away from the rapid descent base 11. The rapid descent button 2 can drive the anti - detachment block 8 to abut against the protective shell 12, restricting the rapid descent button 2 from continuing to move away from the rapid descent base 11 and sliding out of the protective shell 12, effectively reducing the possibility of the rapid descent button 2 sliding out of the protective shell 12. At the same time, it can also position the reset position of the rapid descent button 2, improving the accuracy of the rapid descent button 2's reset.

[0039] Refer to Figure 2 、 Figure 3 As shown in FIGS. 、, the rapid descent valve 3 is installed on the rapid descent base 11, and the rapid descent valve 3 and the rapid descent button 2 are arranged in a staggered manner; the transmission mechanism 4 is installed on the bracket 1. The transmission mechanism 4 is used to press the rapid descent valve 3 when the rapid descent button 2 is pressed. The transmission mechanism 4 includes a rapid descent bracket 41, a connecting frame 42, and a positioning member 43. The rapid descent bracket 41 is rotatably installed on the rapid descent base 11 in the direction towards the rapid descent valve 3. In this embodiment, a semi - circular shaft is installed on the rapid descent base 11, and a concave arc portion is installed on the rapid descent base 11. The concave arc portion abuts against the semi - circular shaft to realize the rotational installation of the rapid descent bracket 41 on the rapid descent base 11. One end of the connecting frame 42 is hinged to the rapid descent bracket 41 through a pin, and the other end of the connecting frame 42 is hinged to the bottom of the rapid descent button 2 through a pin. And the distance between the rotation point of the rapid descent bracket 41 and the connecting frame 42 is greater than the distance between the rapid descent bracket 41 and the rapid descent valve 3, making the lever arm of the rapid descent bracket 41 and the connecting frame 42 greater than the lever arm of the rapid descent bracket 41 and the rapid descent valve 3, reducing the pressing force required for the driver or passenger to press the rapid descent button 2.

[0040] After the driver or passenger presses the rapid descent button 2, the rapid descent button 2 squeezes the connecting frame 42, and the connecting frame 42 then squeezes the rapid descent bracket 41, causing the rapid descent bracket 41 to rotate towards the direction close to the rapid descent valve 3. The rapid descent bracket 41 can then press on the rapid descent valve 3, and the rapid descent valve 3 can be activated to exhaust air to achieve the rapid descent function. Furthermore, the rapid descent button 2 and the rapid descent valve 3 can be installed in a staggered manner according to the seat space, effectively improving the problem that the rapid descent button 2 is installed along the telescopic direction of the rapid descent valve 3 and occupies a large space of the vehicle seat in the telescopic direction of the rapid descent valve 3.

[0041] Refer to Figure 3 、 Figure 4, the positioning member 43 is installed on the rappelling base 11. The positioning member 43 is used to position the rappelling bracket 41 at the position where the rappelling valve 3 is pressed. The positioning member 43 includes a self-locking switch 431 and a latch 432. The self-locking switch 431 is installed on the rappelling base 11, and the latch 432 is installed on the rappelling bracket 41. The self-locking switch 431 is used to lock the latch 432 when the rappelling bracket 41 presses on the rappelling valve 3 and unlock the latch 432 when the rappelling button 2 is continuously pressed in the direction of driving the rappelling bracket 41 to press the rappelling valve 3; Refer to Figure 2 , a spring 6 is installed on the rappelling valve 3. The spring 6 is used to drive the rappelling valve 3 to reset after the self-locking switch 431 unlocks the latch 432.

[0042] During the process that the driver or passenger presses the rappelling button 2 and the rappelling bracket 41 rotates towards the direction close to the rappelling valve 3, the rappelling bracket 41 drives the latch 432 to move towards the direction close to the self-locking switch 431. With the continuous movement of the rappelling bracket 41, the latch 432 presses on the self-locking switch 431, and the self-locking switch 431 locks the latch 432. At the same time, the rappelling valve 3 is pressed by the rappelling bracket 41, causing the spring 6 to be compressed and contract. After the driver or passenger presses the rappelling button 2 again, the rappelling bracket 41 continues to drive the latch 432 to move towards the direction close to the self-locking switch 431, and the self-locking switch 431 can unlock the latch 432. The spring 6 restores its deformation and drives the rappelling valve 3 to reset. The rappelling valve 3 drives the rappelling bracket 41 to rotate towards the direction away from the rappelling valve 3, thereby driving the rappelling bracket 41 to reset. The rappelling bracket 41 can conveniently and quickly drive the rappelling button 2 to pop out and reset through the connecting frame 42, effectively improving the convenience of unlocking the rappelling bracket 41 and the convenience of driving the rappelling button 2 to reset. And only by one rappelling button 2 can the opening and closing of the rappelling function be realized.

[0043] The implementation principle of an automotive seat rapid descent adjustment device according to an embodiment of the present application is as follows: The driver or passenger presses the rapid descent button 2, the rapid descent button 2 squeezes the connecting frame 42, the connecting frame 42 drives the rapid descent bracket 41 to rotate so that the latch 432 is engaged with the self-locking switch 431, and the connecting frame 42 maintains the extrusion of the rapid descent bracket 41 so that the rapid descent bracket 41 presses on the rapid descent valve 3, and the rapid descent valve 3 can be activated to exhaust air to achieve the rapid descent function. At this time, the rapid descent function is turned off. Through the transmission of the force of the connecting frame 42 and the rapid descent bracket 41 on the rapid descent button 2, the rapid descent button 2 and the rapid descent valve 3 can be misaligned and installed according to the seat space, effectively improving the problem that the rapid descent button 2 is installed along the telescopic direction of the rapid descent valve 3 and occupies a large space of the automotive seat in the telescopic direction of the rapid descent valve 3; subsequently, when the driver or passenger presses the rapid descent button 2 again, the self-locking switch 431 releases the latch 432, and the spring 6 can drive the rapid descent bracket 41 to reset. The rapid descent bracket 41 drives the rapid descent button 2 to pop out and reset through the connecting frame 42, and the rapid descent function is turned on again, facilitating the reset of the rapid descent button 2 when the rapid descent function is restored.

[0044] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
