Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a side wing adjustment device for automotive seats and an automotive seat. Background Technology

[0002] When a car changes lanes or goes around a curve, it causes the occupants' bodies to tilt, resulting in poor passenger comfort. Adding side wing adjustment devices to the backrest or seat cushion can help maintain occupant stability and improve passenger comfort.

[0003] Current side wing adjustment devices in car seats are mainly of the airbag type and electric type. Because cars travel at high speeds when changing lanes or entering curves, the side wing adjustment generally needs to be fast as well. However, airbag-type side wing adjustment devices have a slow deflation speed, requiring the use of a pressurized airbag, whose air tank occupies a large space. Existing electric side wing adjustment devices have a rack and pinion mechanism on the side wing; a motor drives the rack and pinion to extend or retract along an arc, causing the side wing to move forward or backward. This type of device is complex in structure, occupies a large space, and has poor adaptability. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a side wing adjustment device for car seats with fast adjustment speed, small space occupation and good adaptability, as well as a car seat.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a side wing adjustment device for automobile seats, comprising:

[0006] Install the frame;

[0007] Side wing supports are provided on the mounting frame and can pivot relative to the mounting frame to retract inward and extend outward;

[0008] The drive motor and transmission mechanism are provided. The drive motor is mounted on the mounting frame, and the transmission mechanism is located between the drive motor and the side wing support. The drive motor can drive the side wing support to pivot through the transmission mechanism.

[0009] Furthermore, the transmission mechanism includes a toothed plate and a connecting bracket connected to the toothed plate, wherein one end of the connecting bracket away from the toothed plate is rotatably connected to the side wing support;

[0010] The output end of the drive motor is equipped with a gear shaft, which meshes with the gear plate and can drive the gear plate to extend and retract.

[0011] Furthermore, the connecting bracket is rotatably connected to the toothed plate;

[0012] When the drive motor drives the gear plate through the gear shaft, the connecting bracket swings and drives the side wing support to pivot.

[0013] Furthermore, the mounting frame is provided with a guide rail, and the toothed plate is disposed on the guide rail and can extend and retract along the guide rail.

[0014] Furthermore, a straight slider extends from each side of the toothed plate, and a groove is provided on each side of the guide rail. One of the straight sliders passes through one of the grooves, and the other straight slider passes through the other groove.

[0015] Furthermore, the tooth width of the gear teeth on the gear shaft is greater than the tooth width of the protruding teeth on the gear plate.

[0016] Furthermore, the side wing support is mounted on the mounting frame via a first pivot, and the side wing support is pivotable along the first pivot;

[0017] The side wing support is provided with a second rotating shaft, which is rotatably connected to the connecting bracket.

[0018] Furthermore, a mounting bracket is provided at each end of the first rotating shaft on the mounting frame, and the two ends of the first rotating shaft are rotatably mounted on the two mounting brackets respectively.

[0019] The mounting frame is provided with a motor bracket, the drive motor is mounted on the motor bracket, the drive motor is arranged along the length direction of the mounting frame, and the first rotating shaft and the second rotating shaft are arranged parallel to the drive motor.

[0022] The technical solution adopted by this utility model to solve its technical problem is to also propose an automobile seat, including a seat cushion and a backrest, wherein the seat cushion and / or the backrest are provided with the above-mentioned side wing adjustment device.

[0023] Compared with the prior art, the present invention has at least the following beneficial effects:

[0024] In this invention, the side wing support can pivot relative to the mounting frame to retract and extend. The drive motor, through a transmission mechanism, drives the side wing support to pivot, causing it to retract or extend, thus achieving electric adjustment of the side wing support to support passengers and effectively ensure passenger comfort. Furthermore, the overall structure of the side wing adjustment device is simple, with a fast adjustment response, small installation space, and does not affect the use of other components, effectively improving the adaptability of the side wing adjustment device. Specifically, the drive motor engages a gear plate via a gear shaft; the gear plate's extension and retraction movement drives the connecting bracket to swing, thereby causing the side wing support to pivot. This ensures a smooth retraction and extension process for the side wing support, and allows for a large adjustable angle of the side wing support even with a small extension and retraction stroke of the gear plate.

[0040] like Figures 1-3 As shown, a side wing adjustment device for a car seat in this embodiment mainly includes: a mounting frame 1, a side wing support 2, a drive motor 3, and a transmission mechanism 4. The transmission mechanism 4 mainly includes a toothed plate 41 and a connecting bracket 42.

[0041] Mounting frame 1 provides mounting positions for other components. When the side wing adjustment device of this embodiment is applied to the backrest, mounting frame 1 is the backrest frame. When the side wing adjustment device of this embodiment is applied to the seat cushion, mounting frame 1 is the seat cushion frame.

[0042] Side wing supports 2 are mounted on the mounting frame 1 and can pivot relative to the mounting frame 1 to retract inwards and extend outwards. Specifically, the side wing supports 2 are mounted on the mounting frame 1 via a first pivot 21, and the side wing supports 2 can pivot along the first pivot 21. Each end of the mounting frame 1 along the first pivot 21 has a mounting bracket, and the two ends of the first pivot 21 are rotatably mounted on the two mounting brackets to ensure reliable rotation of the side wing supports 2. The side wing supports 2 include a support curved panel 23 and multiple reinforcing ribs 24 disposed on the back side of the support curved panel 23. The multiple reinforcing ribs 24 can abut against the mounting frame 1, restricting the position of the side wing supports 2. Comfort components, such as foam, can be installed on the support curved panel 23 to ensure good comfort when passengers lean against it. The side wing supports 2 can rotate to adapt to different passenger postures and different scenarios, effectively improving passenger comfort.

[0043] The drive motor 3 is mounted on the mounting frame 1. Specifically, a motor bracket 12 is provided on the mounting frame 1, and the drive motor 3 is detachably and fixedly mounted on the motor bracket 12. The drive motor 3 is arranged along the length of the mounting frame 1 to ensure that the space occupied by the drive motor 3 is small. Moreover, the motor in this embodiment has a two-way self-locking function. When the side wing support 2 is adjusted to the desired position, the two-way self-locking function of the motor can ensure that the position of the side wing support 2 is stable, and the passenger cannot press the side wing support 2, ensuring that the side wing support 2 has a good support effect.

[0044] A transmission mechanism 4 is disposed between the drive motor 3 and the side support 2. The drive motor 3 can drive the side support 2 to pivot via the transmission mechanism 4. In this embodiment, the transmission mechanism 4 includes a toothed plate 41 and a connecting bracket 42 connected to the toothed plate 41. Specifically, the toothed plate 41 and the connecting bracket 42 are rotatably connected via a rotating shaft. The end of the connecting bracket 42 away from the toothed plate 41 is rotatably connected to the side support 2. Specifically, a second rotating shaft 22 is provided on the side support 2, and the second rotating shaft 22 is rotatably connected to the connecting bracket 42. The first rotating shaft 21, the second rotating shaft 22, and the drive motor 3 are arranged in parallel, meaning the gear shaft 30 on the drive motor 3 is also parallel to the first rotating shaft 21 and the second rotating shaft 22. A gear shaft 30 is disposed at the output end of the drive motor 3, and the gear shaft 30 meshes with the toothed plate 41, driving the toothed plate 41 to extend and retract. The tooth width of the gear teeth on the gear shaft 30 is greater than the tooth width of the convex teeth on the gear plate 41, ensuring stable meshing between the gear shaft 30 and the gear plate 41 and preventing wobbling. In actual use, when the drive motor 3 drives the gear plate 41 to extend and retract via the gear shaft 30, the connecting bracket 42 swings and drives the side wing support 2 to pivot, realizing the inward and outward extension of the side wing support 2.

[0045] In this embodiment of the side wing adjustment device, the side wing support 2 can pivot relative to the mounting frame 1 to retract and extend. The drive motor 3 can drive the side wing support 2 to pivot via the transmission mechanism 4, causing it to retract or extend, thus achieving electric adjustment of the side wing support 2 to support the passenger and effectively ensure passenger comfort. Furthermore, the overall structure of the side wing adjustment device is simple, with a fast adjustment response speed, small installation space, and does not affect the use of other components, effectively improving the adaptability of the side wing adjustment device. Specifically, the drive motor 3 meshes with the gear plate 41 via the gear shaft 30. The extension and retraction movement of the gear plate 41 drives the connecting bracket 42 to swing, thereby driving the side wing support 2 to pivot. This ensures a smooth retraction and extension process for the side wing support 2, and allows for a large adjustable angle of the side wing support 2 even with a small extension and retraction stroke of the gear plate 41.

[0046] like Figure 4 and Figure 5 As shown, the mounting frame 1 of this embodiment is provided with a guide rail 10, and the toothed plate 41 is disposed on the guide rail 10 and can extend and retract along the guide rail 10. Specifically, a straight slider 410 extends from each side of the toothed plate 41, and a groove 101 is provided on each side of the guide rail 10. The straight slider 410 passes through one groove 101, and the other straight slider 410 passes through the other groove 101. The two grooves 101 of the guide rail 10 can guide the two straight sliders 410, ensuring that the toothed plate 41 can only extend and retract along a straight line, and can limit the toothed plate 41 to prevent it from detaching from the guide rail 10, thus ensuring structural stability.

[0047] In actual use, when the position of the side wing support 2 needs to be adjusted, the drive motor 3 operates to rotate the gear shaft 30. The gear shaft 30 meshes with the transmission gear plate 41, causing the gear plate 41 to extend and retract along the guide rail 10. The gear plate 41 drives the connecting bracket 42 to swing, and the connecting bracket 42 drives the side wing support 2 to rotate, thus realizing the inward or outward extension of the side wing support 2. After the adjustment is completed, the drive motor 3 stops working. Utilizing the bidirectional self-locking function of the drive motor 3, the position of the side wing support 2 can be kept stable.

[0048] When the side wing adjustment device of this embodiment is applied to a car seat, it is: a car seat including a seat cushion and a backrest, wherein the side wing adjustment device of this embodiment is provided on both sides of the seat cushion and / or both sides of the backrest.
