Description
Technical Field
[0001] This invention belongs to the field of automotive interior technology, and particularly relates to an automotive seat adjustment mechanism and an automotive. Background Technology
[0002] With the continuous development and progress of society and the continuous improvement of people's living standards, cars have become an essential means of transportation for families. Consequently, people not only have high requirements for the appearance and driving performance of cars, but also place increasingly higher demands on the driving and resting environment inside the vehicle. Car seats provide drivers and passengers with an easy-to-operate, comfortable, and safe driving and riding position. To improve the comfort of drivers and passengers, car seats are generally equipped with a sliding device at the bottom and an angle adjustment device on the seat back. The sliding device allows the car seat to slide, and the angle adjustment device allows the angle between the seat back and the seat cushion to be adjusted.
[0003] Existing cars have front and rear seats. When drivers and passengers need to rest in the rear seats instead of the front seats, it is necessary to increase the space in the rear area of the car for rest. This requires tilting or folding the backrests of the front seats forward and moving the front seats towards the front of the car to increase the resting space in the rear. However, with existing front seats, adjusting the backrest angle and moving the front seat horizontally requires adjusting the front seat separately. It is not possible to adjust the backrest and horizontally of the front seat simultaneously from the rear seat, which increases the inconvenience of adjustment and affects the experience and convenience of drivers and passengers. Therefore, this invention proposes a car seat adjustment mechanism and a car to solve the above problems. Summary of the Invention
[0004] This invention provides a car seat adjustment mechanism that enables simultaneous adjustment of the backrest angle and the translational position of the front seat via a rotary adjuster, thus solving the problems mentioned in the background art.
[0005] In a first aspect, the present invention is implemented as follows: an automobile seat adjustment mechanism, comprising a slide rail, a seat frame, and an adjustment device;
[0006] The slide rail is provided in two sections, which are distributed relatively apart and fixed to the car frame. A rack is fixed on the outer side of the slide rail, and a groove is formed on the slide rail.
[0007] The seat frame includes a seat cushion frame and a backrest frame, which are rotatably connected by a rotating shaft. Two relatively spaced movable seats are fixedly provided at the bottom of the seat cushion frame, and sliders are fixedly provided on the bottom surface of the movable seats. The sliders are slidably connected to the sliding grooves.
[0008] The adjusting device includes a first external gear and a second external gear. The first external gear is located on the outside of the backrest frame and is rotatably connected to the backrest frame via a first rotating shaft. The first external gear is coaxial with the rotating shaft. The second external gear is located on the outside of the movable seat and is rotatably connected to the movable seat via a second rotating shaft. The second external gear meshes with the rack. A sprocket is fixedly provided on the outer wall of the first and second rotating shafts. A chain is sleeved on the outside of the two sprockets. The sprockets and the chain mesh with each other. An internal gear is provided outside the first external gear. The internal gear meshes with the first external gear and is fixedly connected to the backrest frame.
[0009] Preferably, the top surfaces at both ends of the rack are fixedly provided with limiting blocks, which are used to limit the horizontal movement of the car seat.
[0010] Preferably, there are multiple second external gears, which are evenly spaced along the extending direction of the movable seat.
[0011] Preferably, a seat cushion is provided above the seat cushion frame, and the bottom surface of the seat cushion is fixedly connected to the top surface of the seat cushion frame.
[0012] Preferably, the backrest frame has a backrest on the outer side, and the inner side of the backrest is fixedly connected to the backrest frame.
[0013] Preferably, an adjuster is fixedly provided on the end face of the first rotating shaft.
[0014] Preferably, the regulator is provided with a cross-shaped rotating protrusion to facilitate rotation of the regulator.
[0015] Preferably, the adjuster is equipped with a locking device to prevent the car seat from shifting automatically.
[0016] Preferably, a curtain is provided between the seat cushion and the slide rail to cover the seat cushion frame and the rack.
[0017] Second, an automobile, including the automobile seat adjustment mechanism described in any one of the first aspects.
[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] 1. When the car seat adjustment mechanism of the present invention needs to adjust the backrest angle and the front seat translation position, the cross protrusion on the adjuster is rotated clockwise. The adjuster drives the first rotating shaft to rotate, thereby driving the first external gear to rotate. At this time, the internal gear and the chain will rotate. The rotation of the internal gear drives the backrest closer to the seat cushion. The rotation of the chain drives the second rotating shaft to rotate, thereby driving the second external gear to translate on the rack and move closer to the front of the car. In this way, the adjustment of the car seat backrest angle and the translation position of the front seat can be realized by operating the adjuster. At this time, the rear seat space becomes larger, which is suitable for the driver and passengers to rest in the rear seat, which is convenient and quick.
[0020] 2. When the car seat adjustment mechanism of the present invention needs to reset the car seat, the cross protrusion on the adjuster is rotated counterclockwise. The adjuster drives the first rotating shaft to rotate, thereby driving the first external gear to rotate. At this time, the internal gear and the chain will also rotate. The rotation of the internal gear drives the backrest away from the seat cushion. The rotation of the chain drives the second rotating shaft to rotate, thereby driving the second external gear to move away from the front of the car on the rack. In this way, the car seat can be reset by operating the adjuster, which is convenient and quick.
[0021] 3. This invention allows drivers and passengers to quickly and conveniently adjust car seats in both the front and rear seats, preventing situations where the rear seat cannot be adjusted in the front seat, and the operation is convenient and quick. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0036] Please see Figures 1 to 4 The present invention provides a technical solution: a car seat adjustment mechanism, including a slide rail 1, a seat frame 2 and an adjustment device 3; the slide rail 1 is provided with two slide rails, which are distributed relatively at intervals and fixed on the car frame, and a rack 11 is fixed on the outer side of the slide rail 1, and a slide groove 12 is provided on the slide rail 1.
[0037] The seat frame 2 includes a seat cushion frame 21 and a backrest frame 22. The seat cushion frame 21 and the backrest frame 22 are rotatably connected by a rotating shaft. Two relatively spaced movable seats 23 are fixedly provided at the bottom of the seat cushion frame 21. A slider 24 is fixedly provided on the bottom surface of the movable seat 23. The slider 24 is matched and slidably connected with the slide groove 12.
[0038] The adjusting device 3 includes a first external gear 31 and a second external gear 32. The first external gear 31 is located on the outside of the backrest frame 22 and is rotatably connected to the backrest frame 22 through a first rotating shaft 311. The first external gear 31 is coaxial with the rotating shaft. The second external gear 32 is located on the outside of the movable seat 23 and is rotatably connected to the movable seat 23 through a second rotating shaft 321. The second external gear 32 is meshed with a rack 11. A sprocket is fixedly provided on the outer wall of the first rotating shaft 311 and the second rotating shaft 321. A chain 33 is sleeved on the outside of the two sprockets. The sprockets and the chain 33 mesh with each other. An internal gear 34 is provided outside the first external gear 31. The internal gear 34 meshes with the first external gear 31 and is fixedly connected to the backrest frame 22.
[0039] In this embodiment, the first rotating shaft 311 is fixedly connected to the first external gear 31 and rotatably connected to the backrest frame 22. The second rotating shaft 321 is fixedly connected to the second external gear 32 and rotatably connected to the movable seat 23. When the car seat adjustment mechanism needs to adjust the angle of the backrest 5 and the translation position of the front seat, the cross protrusion on the adjuster 35 is rotated clockwise. The adjuster 35 drives the first rotating shaft 311 to rotate, thereby driving the first external gear 31 to rotate. At this time, the internal gear 34 and the chain 33 will both rotate. The rotation of the internal gear 34 drives the backrest 5 closer to the seat cushion 4, and the rotation of the chain 33 drives the second rotating shaft 321 to rotate, thereby driving the second external gear 32 to translate on the rack 11. By operating the adjuster 35 near the front of the vehicle, the angle of the car seat backrest 5 and the position of the front seat can be adjusted. This increases the rear seat space, making it more convenient for drivers and passengers to rest. When the car seat needs to be reset, rotating the cross-shaped protrusion on the adjuster 35 counterclockwise rotates the first rotating shaft 311, which in turn rotates the first external gear 31. This causes the internal gear 34 and chain 33 to rotate. The rotation of the internal gear 34 moves the backrest 5 away from the seat cushion 4, while the rotation of the chain 33 rotates the second rotating shaft 321, which in turn moves the second external gear 32 away from the front of the vehicle on the rack 11. This allows the car seat to be reset quickly and easily. With this method, drivers and passengers can quickly and easily adjust the car seat from both the front and rear seats, avoiding the situation where the rear seat cannot be adjusted from the front.
[0040] For further details, please refer to Figure 2 Limiting blocks 111 are fixedly provided on the top surfaces of both ends of the rack 11. The limiting blocks 111 are used to limit the horizontal movement of the car seat.
[0041] In this embodiment, limit blocks 111 are fixedly provided on the top surfaces of both ends of the rack 11. The limit blocks 111 can restrict the second external gear 32 from moving out of the range of the rack 11, which is used to limit the horizontal movement of the car seat and prevent the seat from moving out of the slide rail 1 and being unable to return to its original position.
[0042] For further details, please refer to Figure 2 Multiple second external gears 32 are provided, and the multiple second external gears 32 are evenly spaced along the extension direction of the movable seat 23.
[0043] In this embodiment, multiple second external gears 32 are evenly spaced along the extension direction of the movable seat 23. In this way, the active second external gear 32, which is connected to the first external gear 31 through the chain 33, can drive multiple second external gears 32 to move on the rack 11. The simultaneous movement of multiple second external gears 32 facilitates the balance of the car seat and also speeds up the translation.
[0044] For further details, please refer to Figure 1 A seat cushion 4 is provided above the seat cushion frame 21, and the bottom surface of the seat cushion 4 is fixedly connected to the top surface of the seat cushion frame 21.
[0045] In this embodiment, the seat cushion 4 increases the comfort of the driver and passengers when sitting. The bottom surface of the seat cushion 4 is fixedly connected to the top surface of the seat cushion frame 21, so that the seat cushion 4 can move synchronously when the car seat is moved, and the seat cushion 4 is prevented from falling off the seat cushion frame 21.
[0046] For further details, please refer to Figure 1 The backrest frame 22 has a backrest 5 on the outside, and the backrest 5 is fixedly connected to the backrest frame 22 on the inside.
[0047] In this embodiment, the backrest 5 increases the comfort of the driver and passengers when they lean back in their seat position. The inner side of the backrest 5 is fixedly connected to the backrest frame 22, so that the backrest 5 can move synchronously when the car seat is moved, and the backrest 5 is prevented from falling off the backrest frame 22.
[0048] For further details, please refer to Figure 1 An adjuster 35 is fixedly provided on the end face of the first rotating shaft 311.
[0049] In this embodiment, the adjuster 35 is used to rotate the first external gear 31 clockwise or counterclockwise.
[0050] For further details, please refer to Figure 1 The regulator 35 is provided with a cross-shaped rotating protrusion to facilitate the rotation of the regulator 35.
[0051] In this embodiment, the cross-shaped rotating protrusion makes it convenient for drivers and passengers to operate the adjuster 35, saving time and effort.
[0052] Furthermore, the adjuster 35 is equipped with a locking device to prevent the car seat from shifting automatically.
[0053] In this embodiment, when the locking device is locked, it prevents the car seat from shifting automatically; when the locking device is unlocked, it facilitates the operation of the adjuster 35.
[0054] Furthermore, a curtain is provided between the seat cushion 4 and the slide rail 1 to cover the seat cushion frame 21 and the rack 11.
[0055] In this embodiment, the curtain can enhance the aesthetics of the seat. If both the seat cushion frame 21 and the rack 11 are exposed, it will affect the aesthetics of the car interior.
[0056] An automobile includes the automobile seat adjustment mechanism of any of the above embodiments.
[0057] The working principle and usage process of this invention: The first rotating shaft 311 is fixedly connected to the first external gear 31 and rotatably connected to the backrest frame 22; the second rotating shaft 321 is fixedly connected to the second external gear 32 and rotatably connected to the movable seat 23; when the car seat adjustment mechanism needs to adjust the angle of the backrest 5 and the position of the front seat, by rotating the cross protrusion on the adjuster 35 clockwise, the adjuster 35 drives the first rotating shaft 311 to rotate, thereby driving the first external gear 31 to rotate. At this time, the internal gear 34 and the chain 33 will both rotate. The rotation of the internal gear 34 drives the backrest 5 closer to the seat cushion 4, and the rotation of the chain 33 drives the second rotating shaft 321 to rotate, thereby driving the second external gear 32 to rotate on the rack 11. By moving the adjuster 35 upwards closer to the front of the car, the angle of the backrest 5 and the position of the front seat can be adjusted. This increases the rear seat space, making it more convenient and easier for passengers to rest. When the car seat needs to be reset, the cross protrusion on the adjuster 35 is rotated counterclockwise. The adjuster 35 drives the first rotating shaft 311 to rotate, which in turn drives the first external gear 31 to rotate. At this time, the internal gear 34 and the chain 33 will also rotate. The rotation of the internal gear 34 moves the backrest 5 away from the seat cushion 4, and the rotation of the chain 33 drives the second rotating shaft 321 to rotate, which in turn drives the second external gear 32 to move away from the front of the car on the rack 11. This allows the car seat to be reset quickly and easily.
[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
