Automobile seat adjustment structure

Abstract

The present invention relates to the technical field of automobile-related equipment, and discloses an automobile seat adjustment structure, comprising a main body, the top of which is rotatably connected to a backrest. In the present invention, when the backrest drives the center rod to continue rotating, the fan-shaped tooth plate will slide and rub against the elastic plate along the two arcs, and at the same time, under the guidance of the arc, it will slide downward on the side wall of the spring plate and compress the spring on the spring plate. At this time, the backrest will form a progressive friction sliding under the action of the friction between the fan-shaped tooth plate and the two side walls of the elastic plate. At this time, the backrest can be reset relatively slowly when resetting, while slowing down the backrest reset speed and ensuring that the backrest is slowly reset within a safe range, reducing the situation in which the backrest rebounds quickly under the action of the elastic release of the torsion spring when resetting the backrest, causing collision with the user and causing injury to the user, thereby improving the stability of the adjustable seat and ensuring safety during adjustment.

Description

Technical Field

[0001] The present invention relates to the technical field of automobile-related equipment, in particular to an automobile seat adjustment structure. Background Art

[0002] Car seats are a key component of vehicle interiors, providing support and safety for passengers. Comfortable and functional seats can help the vehicle gain a competitive edge in the market. To facilitate ingress and egress and ensure greater trunk storage space, folding and flipping backrests are essential features of car seats. The key component for achieving this is the seatback adjustment mechanism.

[0003] In order to adjust the seat to a comfortable posture before driving the car, the backrest of the car seat needs to be adjusted. Since the adjustment between the backrest and the seat cushion on the car seat is limited and reset by torsion springs and ratchets, and the torsion springs between the adjusted seat and the backrest will be in a compressed state, when the backrest is adjusted again, the ratchets in the seat will be in a separated state. At this time, the backrest on the seat is prone to rapid rebound due to the release of the elastic potential energy of the torsion spring, which can easily cause the backrest to collide with the user during rapid rebound, causing injury to the user and affecting the stability and safety of the seat during adjustment.

[0038] The present invention has the following beneficial effects:

[0039] 1. The present invention, through the elastic component and the second elastic sheet, when the backrest drives the center rod to continue to rotate, the sector tooth plate will slide and rub against it along the guidance of the arc of the second elastic sheet, and at the same time, under the guidance of the arc, it will slide downward on the side wall of the spring plate and compress the spring on the spring plate. At this time, the backrest will form a progressive friction sliding under the action of the friction between the sector tooth plate and the side wall of the second elastic sheet. At this time, the backrest can be reset more slowly when resetting, while slowing down the resetting speed of the backrest and ensuring that the backrest is slowly reset within a safe range, reducing the situation where the backrest rebounds quickly under the action of the elastic release of the torsion spring when resetting the backrest, causing collision with the user and causing injury to the user, thereby improving the stability of the adjustable seat and ensuring safety during adjustment.

[0040] 2. The present invention uses the auxiliary component and the bending component. Since the contact tightness between the elastic piece 2 and the sector tooth plate is not great, the friction between the sector tooth plate and the elastic piece 2 will be reduced. At this time, the backrest will rebound relatively quickly. If it is found that the reset speed of the backrest is too fast, it is only necessary to pull the adjustment plate upward to the limit to limit the rotation speed of the sector tooth plate and the backrest again, thereby avoiding the situation where the backrest is reset laborious and difficult to reset due to the slow reset speed of the backrest when adjusting the backrest. The reset speed of the backrest is adjusted according to different usage experiences, which can enhance the rapid response and applicability of the adjustment device, while also reducing the reset time during adjustment and improving the adjustment efficiency.

[0041] 3. The present invention uses a bending component, when multiple short shafts move downward with the arc plate, the downward movement of the short shafts will push the flip plate to rotate in the limit frame. At this time, the bottom of the rotating flip plate will contact the side wall of the elastic piece 2 and slide the limit shaft on the side wall of the flip plate into the flip plate. At this time, a relatively vertical parallel state will be formed between the multiple flip plates. When the fan-shaped tooth plate causes local shaking of the elastic piece 2 during the sliding friction between the bottom and the side wall of the elastic piece 2 to reset, the support after the rotation of the flip plate and the downward pressure generated by the multiple short shafts can limit the shaking of the elastic piece 2 when the fan-shaped tooth plate is reset, further enhancing the adjustment stability while reducing the feeling of frustration in the backrest caused by the shaking of the fan-shaped tooth plate and the elastic piece 2 when the fan-shaped tooth plate is reset, thereby further enhancing the stability and adjustment efficiency of the device.

[0042] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

When the angle of the backrest 101 needs to be adjusted, the staff first pulls the adjustment plate 112 upward. When the adjustment plate 112 is pulled, it will rotate upward on the outer surface of the fixed shaft 113.

A torsion spring 222 is provided on the side of the fixing plate 221 close to the L rod 111 . The torsion spring 222 is fixedly connected to the outer surface of the fixing shaft 113 .

[0066] The auxiliary mechanism 3 includes a central rod 301 disposed on a side of the fixing plate 221 away from the L-rod 111. The auxiliary mechanism 3 includes:

[0067] The limiting assembly 31 is installed on the side wall of the central rod 301;

[0068] A bending assembly 32, the bending assembly 32 includes a side wall provided on the limiting assembly 31;

[0070] The outer surface of the fixed shaft 113 is rotatably connected to the adjustment plate 112 , and the end of the adjustment plate 112 away from the fixed shaft 113 slides through the outer wall of the fixed shell 201 ;

[0071] Among them, the side wall of the adjustment plate 112 is provided with an obtuse-angle groove 114, and the bottom of the adjustment plate 112 is rotatably connected to a linear spring, which is rotatably connected to the inner wall of the fixed shell 201. At this time, the backrest 101 can be rotated backward to adjust its angle. At this time, the torsion spring 222 will be compressed. When the backrest 101 needs to be reset, it is only necessary to pull the adjustment plate 112 again. The backrest 101 will be reset under the elastic release of the torsion springs 222 on both sides, completing the angle adjustment of the device.

[0072] The auxiliary component 21 includes a rack 211 rotatably connected to the side of the main body 1 close to the fixed shell 201. The side wall of the rack 211 is meshed with a tooth plate 212, and the side wall of the tooth plate 212 is fixedly connected to the fixed plate 221.

[0073] A long rod is fixedly connected to one side of the rack 211 close to the adjustment plate 112 , and the outer surface of the long rod is slidably connected to the inside of the obtuse-angle groove 114 .

[0074] The top of the torsion spring 222 is fixedly connected to the side wall of the fixing plate 221;

[0075] The elastic component 22 includes a connecting plate 223 fixedly connected to the fixing plate 221 on the side close to the backrest 101, and the connecting plate 223 is fixedly connected to the side wall of the backrest 101;

[0076] Among them, a spring plate 224 is fixedly connected to one side of the fixing plate 221 close to the connecting plate 223;

[0077] A triangular plate is provided on the side of the connecting plate 223 close to the spring plate 224, and a fixing column is fixedly connected to the side of the triangular plate close to the main body 1. The fixing column passes through the side wall of the connecting plate 223 and is fixedly connected to the main body 1. The reset rotation of the backrest 101 will drive the fixing plate 221 to rotate through the connecting plate 223, and when the fixing plate 221 rotates, it will drive the fan-shaped tooth plate 311 to rotate synchronously through the spring plate 224.

[0078] The center rod 301 slides through the side wall of the spring plate 224;

[0079] The limiting assembly 31 includes a sector-shaped tooth plate 311 fixedly connected to the side wall of the center rod 301. The top outer wall of the sector-shaped tooth plate 311 is provided with a plurality of spring shafts 312. The spring ends of the spring shafts 312 are fixedly connected to the side wall of the sector-shaped tooth plate 311.

[0080] The bending assembly 32 includes an elastic piece 321 rotatably connected to the side wall of the triangular plate. One end of the elastic piece 321 close to the rack 211 is rotatably connected to the side wall of the rack 211.

[0081] The side wall of the elastic piece 1 321 is provided with a sliding groove, and the elastic piece 2 322 is slidingly provided inside the sliding groove. The left side of the elastic piece 2 322 is fixedly connected to the side wall of the main body 1. Since the top of the sector tooth plate 311 contacts the side wall of the elastic piece 2 322, when the backrest 101 drives the fixed plate 221 to reset, the several spring shafts 312 on the sector tooth plate 311 will be between the sector tooth plate 311 and the side wall of the elastic piece 2 322. When the sector tooth plate 311 continues to reset and rotate as the backrest 101 continues to reset, the spring shaft 312 will be in a stretched state due to the friction of the side wall of the elastic piece 2 322 during sliding and limit the sliding of the sector tooth plate 311 on the side wall of the elastic piece 2 322 through friction.

[0082] The top of the second elastic piece 322 is fixedly connected to a plurality of limit frames 323, and the side walls of the limit frames 323 are rotatably connected to the flip plates 324, and the side walls of the flip plates 324 are provided with notches;

[0083] Among them, the bottom of the flip plate 324 is fixedly connected to an auxiliary spring, and the bottom of the auxiliary spring is fixedly connected to the side wall of the elastic piece 2 322;

[0084] The side wall of the flip plate 324 is fixedly connected to a limit rod, and the limit rod is slidably connected in the notch.

[0085] The pushing assembly 33 includes two C-shaped blocks 331 slidably connected to the outer surface of the elastic piece 1 321. The side walls of the C-shaped blocks 331 are rotatably connected to a strip plate, and a bending spring is fixedly connected between the two strip plates.

[0086] A spring rod 332 is slidably passed through the side wall of the strip plate, and a rectangular plate is rotatably connected between the two spring rods 332;

[0087] Among them, the rectangular plate is fixedly connected to the side of the elastic piece 1 321 with an arc plate 333, and the arc plate 333 is fixedly connected to the side of the elastic piece 1 321 with several short shafts, the outer surface of the short shaft is in contact with the side wall of the flip plate 324, and the fan-shaped tooth plate 311 will slide and rub against it along the arc of the elastic piece 2 322, and at the same time, slide downward on the side wall of the spring plate 224 under the guidance of the arc and compress the spring on the spring plate 224. At this time, the backrest 101 will form a progressive friction sliding under the action of the friction force between the fan-shaped tooth plate 311 and the side wall of the elastic piece 2 322. At this time, the backrest 101 can be reset more slowly when resetting, slowing down the reset speed of the backrest 101 while ensuring that the backrest 101 is slowly reset within a safe range.

[0088] During use, when the angle of the backrest 101 needs to be adjusted, the staff first pulls the adjustment plate 112 upwards. When the adjustment plate 112 is pulled, it will rotate upward on the outer surface of the fixed shaft 113. At the same time, when the adjustment plate 112 rotates upward, it will guide the long rod on the rack 211 through the inclined part in the obtuse-angle groove 114, so that it drives the rack 211 to separate from the rack plate 212. At this time, the backrest 101 can be rotated backward to adjust its angle. At this time, the torsion spring 222 will be compressed. When the backrest 101 needs to be reset, it is only necessary to pull the adjustment plate 112 again. The backrest 101 will be reset under the elastic release of the torsion springs 222 on both sides, completing the angle adjustment of the device.

[0089] When the adjustment plate 112 is pulled upward to separate the rack 211 from the tooth plate 212, the rotation of the rack 211 will drive the front end of the elastic piece 1 321 and pull the elastic piece 1 321. Since the end of the elastic piece 1 321 away from the rack 211 is connected to the rotation of the triangular plate, when the front end of the elastic piece 1 321 is pulled, the elastic piece 1 321 will be deformed and contact the top of the sector tooth plate 311 through the elastic piece 2 322. At this time, the side wall of the elastic piece 2 322 will have a certain curvature, and the backrest 1 When the backrest 101 is reset, the reset rotation of the backrest 101 will drive the fixed plate 221 to rotate through the connecting plate 223. When the fixed plate 221 rotates, the fan-shaped tooth plate 311 will be driven to rotate synchronously through the spring plate 224. Since the top of the fan-shaped tooth plate 311 is in contact with the side wall of the elastic piece 2 322, when the backrest 101 drives the fixed plate 221 to reset, the several spring shafts 312 on the fan-shaped tooth plate 311 will be between the fan-shaped tooth plate 311 and the side wall of the elastic piece 2 322. When 101 continues to reset and rotate, the spring shaft 312 will be in a stretched state due to the friction of the side wall of the elastic piece 2 322 when sliding, and the friction force will be used to limit the sliding of the sector tooth plate 311 on the side wall of the elastic piece 2 322. At this time, when the backrest 101 drives the center rod 301 to continue to rotate, the sector tooth plate 311 will slide and rub against the elastic piece 2 322 along the arc, and at the same time, it will slide downward on the side wall of the spring plate 224 under the guidance of the arc and compress the spring on the spring plate 224. At this time, the backrest 101 will be on the sector tooth plate Under the action of the friction force between 311 and the side wall of the elastic piece 2 322, a progressive friction sliding is formed. At this time, the backrest 101 can be reset more slowly when it is reset, which slows down the reset speed of the backrest 101 while ensuring that the backrest 101 is slowly reset within a safe range, reducing the possibility that the backrest 101 will rebound quickly under the elastic release of the torsion spring 222 when resetting the backrest 101, causing collision with the user and causing injury to the user, thereby improving the stability of the seat adjustment while ensuring safety during adjustment.

[0090] When the adjustment plate 112 is pulled to make the backrest 101 move slowly under the action of friction resistance, since the reset adjustment speed of the backrest 101 is relatively slow under the action of friction resistance, the adjustment plate 112 can be pulled to the general angle of the limit range first to separate the rack 211 from the tooth plate 212. At this time, the rotation angle of the rack 211 will be reduced. At the same time, after the rack 211 rotates, the stretching amplitude of the elastic piece 1 321 will be reduced. When the elastic piece 1 321 is stretched, it will pass through the rectangular groove opened on the elastic piece 1 321. When the elastic piece 1 321 is stretched obliquely downward, it will push the elastic piece 2 322 to contact with the top of the fan-shaped tooth plate 311 through the rectangular groove. The contact tightness is not great, so the friction between the sector tooth plate 311 and the elastic piece 2 322 will be reduced, and the backrest 101 will rebound relatively quickly at this time. If it is found that the reset speed of the backrest 101 is too fast, the adjustment plate 112 only needs to be pulled up to the limit to limit the rotation speed of the sector tooth plate 311 and the backrest 101 again, avoiding the situation where the backrest 101 is reset too slowly when adjusting the backrest 101. The reset speed of the backrest 101 adjusted according to different usage experiences can enhance the rapid response and applicability of the adjustment device, while also reducing the reset time during adjustment and improving the adjustment efficiency during adjustment.

[0091] When the rack 211 rotates and stretches the elastic piece 1 321 and causes it to be stretched, the deformation of the elastic piece 1 321 will cause the two C-shaped blocks 331 to slide close to each other under the elastic potential energy of the bending spring. When the two C-shaped blocks 331 approach each other, the approach of the two C-shaped blocks 331 will cause the spring rod 332 to push the rectangular plate downward. When the rectangular plate moves downward, it will drive the arc plate 333 and the multiple short shafts on the side wall of the arc plate 333 to slide downward synchronously. When the multiple short shafts move downward with the arc plate 333, the downward movement of the short shafts will push the flip plate 324 to rotate in the limit frame 323. At this time, the bottom of the rotating flip plate 324 will contact the side wall of the elastic piece 2 322 and When the cam 324 is in the upright position, the cam 324 will move in a reverse direction and the cam 324 will move in a reverse direction, thereby preventing the cam 324 from moving in a reverse direction and preventing the cam 324 from moving in a reverse direction.

[0092] It should be noted that when the elastic piece 321 is reset to a bent state, the bulge of the elastic piece 321 will generate a bulge between the two C-shaped blocks 331 when the elastic piece 321 is bent and push the two C-shaped blocks 331 to slide away from each other and stretch the bending spring.

[0093] Compared with the damper, the resistance of the damper is usually linear, and it is difficult to dynamically adjust according to the rotation angle and reset speed of the backrest 101. This design can achieve a nonlinear damping effect in which the larger the angle, the stronger the resistance through the contact between the curvature of the elastic piece 2 322 and the elastic piece 1 321 and the fan-shaped tooth plate 311 and the plurality of spring shafts 312. In the initial stage of the reset of the backrest 101, the stretching amount of the elastic piece 1 321 is small, and the resistance is small, which reduces the jamming during startup. In the middle and late stages of the reset, the deformation clamp of the elastic piece 2 322 is closer to the extrusion of the fan-shaped tooth plate 311 and the spring shaft 312, and the resistance is increased, which can suppress the impact at the end.
