Description

Technical Field

[0001] This utility model relates to the field of automotive seat backrest side wing technology, specifically to an adjustable structure for automotive seat backrest side wing. Background Technology

[0002] To ensure a comfortable ride for passengers, car seat backs are typically equipped with shoulder and neck supports. In addition, side wing backs are also provided, which allow the occupant's body to better conform to the seat, reducing discomfort and improving comfort and safety.

[0003] However, in the existing technology, the side wings of car seat backrests are mostly fixed and cannot be adjusted. Due to the differences in the body shape of passengers, this results in some passengers not being able to get the comfort they want when riding. Utility Model Content

[0004] In view of this, the present invention provides an adjustable structure for the side wings of a car seat back, which is designed to adjust the opening and closing degree of the side wings of the backrest, thereby meeting the support needs of passengers of different body types for the side wings of the backrest.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A car seat backrest side wing adjustment structure includes a backrest frame, on which a side wing plate is folded and installed in the width direction. The backrest frame is characterized by having a longitudinal rotating shaft and a horizontal rotating shaft rotatably mounted on its side. The longitudinal rotating shaft extends along the height direction of the backrest frame, and the horizontal rotating shaft extends along the width direction of the backrest frame. The inner end of the side wing plate is fixed to the longitudinal rotating shaft. A drive motor for driving the horizontal rotating shaft is mounted on the backrest frame. The horizontal and longitudinal rotating shafts are arranged alternately in space and are poweredly connected by a vertical transmission assembly.

[0007] With the above structure, the horizontal rotating shaft is driven by a drive motor, and the vertical rotating shaft is driven by a vertical transmission component, which enables the side wing to rotate relative to the seat back. This can meet the support needs of passengers of different body types for the side wing of the backrest. In addition, the staggered arrangement of the horizontal and vertical rotating shafts allows the power system of the side wing to be installed more compactly.

[0008] Preferably, the vertical transmission assembly includes a meshing worm and a worm wheel. The worm is fixedly connected to or integrally formed on the end of the horizontal shaft, and the worm wheel is fixedly sleeved on the end of the longitudinal shaft. Using this structure, the power is switched from the horizontal to the vertical direction through the cooperation of the worm and worm wheel, which not only allows the side wing plates to rotate but also makes the overall installation structure more compact.

[0009] Preferably, the worm gear has a fan-shaped block structure with worm gear teeth on its end curved surface. Using this structure, the fan-shaped design allows for reasonable control of the side wing plate's flip angle.

[0010] Preferably, the end surface of the worm gear has a concave structure. This structure increases the meshing area between the worm gear and the worm, resulting in more stable meshing and transmission.

[0011] Preferably, the backrest frame is provided with a mounting bracket, and the upper end of the longitudinal rotating shaft is rotatably supported within the mounting bracket. This structure enables the longitudinal rotating shaft to rotate in a directional and stable manner.

[0012] Preferably, the mounting bracket has an installation space, and both the worm gear and the worm are disposed within the installation space. This structure protects the worm and worm gear, preventing foreign objects from affecting their service life.

[0013] Preferably, the side wing plate has a mounting block on its side, the mounting block has a mounting hole, and the longitudinal rotating shaft is fixedly inserted into the mounting hole. This structure allows the side wing plate to be stably mounted on the longitudinal rotating shaft.

[0014] Preferably, two sets of side wing plates are provided, symmetrically arranged on the left and right sides of the backrest frame, and each set of side wing plates is equipped with a corresponding drive motor. This structure allows for individual adjustment of each side wing plate, further ensuring the support needs of occupants of different body types for the backrest side wings.

[0015] Preferably, the backrest frame has foam integrated on its front side, and the foam side has a clearance groove, with the side wing plate positioned within the area corresponding to the clearance groove. This structure ensures that the entire backrest surface remains flat when the side wing plate is laid flat, thus guaranteeing passenger comfort.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The car seat backrest side wing adjustment structure provided by this utility model uses a drive motor to drive the horizontal rotating shaft to rotate, and then the vertical transmission component drives the longitudinal rotating shaft to rotate, so that the side wing plate can rotate relative to the seat backrest, thereby meeting the support needs of passengers of different body sizes for the side wing of the backrest. In addition, the staggered arrangement of the horizontal rotating shaft and the longitudinal rotating shaft can make the power system of the side wing plate more compact.

[0018] 2. Each of the two side wing panels is controlled independently by a drive motor, which makes the combination of the adjustment angles of the two sets of side wing panels more diverse and further ensures the support needs of passengers of different body types for the backrest side wings.

[0026] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0027] like Figure 3 and Figure 4 As shown, an adjustable side wing structure for a car seat back includes a backrest frame 1. A side wing plate 2 is folded and installed on the side of the backrest frame 1 in the width direction. A longitudinal rotating shaft 3 and a horizontal rotating shaft 10 are rotatably installed on the side of the backrest frame 1. The longitudinal rotating shaft 3 extends along the height direction of the backrest frame 1, and the horizontal rotating shaft 10 extends along the width direction of the backrest frame 1. The inner end of the side wing plate 2 is fixed to the longitudinal rotating shaft 3. A drive motor 5 for driving the horizontal rotating shaft 10 to rotate is also fixedly installed on the backrest frame 1. The horizontal rotating shaft 10 and the longitudinal rotating shaft 3 are arranged alternately in space and are poweredly connected to each other through a vertical transmission component.

[0028] The horizontal rotating shaft 10 is driven to rotate by the drive motor 5, and the vertical transmission component drives the longitudinal rotating shaft 3 to rotate, thereby realizing the electric control of the side wing plate 2 to rotate, thus meeting the support needs of different body types for the side wing of the seat back. In addition, the staggered arrangement of the horizontal rotating shaft 10 and the longitudinal rotating shaft 3 optimizes the layout of the drive motor 5, making the overall structure more compact.

[0029] Specifically, the vertical transmission component includes a worm 6 and a worm wheel 4 that mesh with each other. In this embodiment, the worm 6 is fixedly connected to the end of the horizontal rotating shaft 10 through a coupling 8. In addition, the worm 6 can also be integrally formed at the end of the horizontal rotating shaft 10. The worm wheel 4 is fixedly sleeved on the upper end of the longitudinal rotating shaft 3. With such a design, through the cooperation of the worm wheel 4 and the worm 6, the power is converted from the horizontal direction to the vertical direction, thereby realizing the rotation of the side wing plate 2. At the same time, the layout position of the driving motor 5 is also optimized, making the overall structure more compact.

[0030] As Figure 3 and Figure 5 shown, in this embodiment, the worm wheel 4 has a fan-shaped block structure, and worm wheel teeth 4a are provided on the end surface thereof. Through the design of the fan-shaped structure, the rotation angle of the side wing plate 2 can be limited.

[0031] Furthermore, in this embodiment, the arc surface at the end of the worm wheel 4 is concave. With such a design, the contact area between the worm 6 and the worm wheel teeth 4a can be increased, thereby ensuring more stable transmission between the worm 6 and the worm wheel 4.

[0032] As Figure 2 shown, a mounting bracket 7 is fixedly installed on the backrest frame 1, and the upper end of the longitudinal rotating shaft 3 is rotationally supported within the mounting bracket 7. To ensure more stable rotation of the longitudinal rotating shaft 3, in this embodiment, a fixed bracket 9 is further provided on the backrest frame 1, and the middle and lower ends of the longitudinal rotating shaft 3 are rotationally supported inside the fixed bracket 9.

[0033] In this embodiment, the mounting bracket 7 has a mounting space 7a inside, and both the worm wheel 4 and the worm 6 are arranged inside the mounting space 7a. As Figure 4 shown, the overall mounting space 7a has a "convex" shape structure. Among them, the worm 6 is rotatably arranged in the smaller rectangular space, and the worm wheel 4 is rotatably arranged in the larger rectangular space. When the worm wheel 4 rotates to a certain angle, its end can abut against the edge position of the mounting space 7a, thereby playing a role in limiting the rotation of the side wing plate 2. Arranging the worm wheel 4 and the worm 6 inside the mounting bracket 7 can prevent foreign objects from intervening between the worm wheel 4 and the worm 6 and affecting their overall service life.

[0034] As Figure 2 and Figure 6 shown, an installation block 2a is fixedly installed on the side of the side wing plate 2 through bolts, and an installation hole 2a1 is formed on the installation block 2a. The longitudinal rotating shaft 3 is fixedly passed through the installation hole 2a1. With such a design, it can ensure that the side wing plate 2 is stably installed on the longitudinal rotating shaft 3 and can rotate together with the longitudinal rotating shaft 3.

[0035] As Figure 1As shown in this embodiment, there are two sets of side wing plates 2, which are symmetrically arranged on the left and right sides of the backrest frame 1. Each set of side wing plates 2 is equipped with a corresponding drive motor 5. Through the two drive motors 5, the two side wing plates 2 can be adjusted independently to meet the needs of passengers of different body sizes for the drive motors 5.

[0036] like Figure 7 As shown, foam 11 is integrated on the front side of the backrest frame 1, and a relief groove 11a is provided on the side of the foam 11. The side wing plate 2 is set in the area corresponding to the relief groove 11a. With this design, when the side wing plate 2 is in the flat state, the entire backrest surface can be kept flat, thereby ensuring the comfort of the passenger.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
