Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology, and in particular relates to a follow-up armrest horizontal mechanism for automotive seats. Background Technology

[0002] Car seat armrests are used to support passengers' elbows, thereby increasing comfort.

[0003] Currently, most hybrid, gasoline, and pure electric vehicles on the market do not have armrests or adjustable armrests. Some zero-gravity seats, due to significant backrest adjustments, cannot maintain a horizontal position for the armrests, and the armrest angle cannot be customized. Furthermore, when the seat backrest is adjusted, the armrests move up and down with the seat, thus failing to effectively support the elbows. Therefore, they are not equipped with seat armrests. Thus, this utility model proposes a follow-up armrest leveling mechanism for car seats to solve the problem of armrests not being able to maintain a horizontal position. Utility Model Content

[0004] This utility model provides a follow-up armrest horizontal mechanism for automobile seats, which aims to solve the problems mentioned in the background art.

[0005] This utility model is implemented as follows: a follow-up armrest horizontal mechanism for a car seat, including an angle adjustment motor, a backrest rotating shaft, a transmission chain, a transmission shaft, a follow-up reverse gear, and an armrest frame;

[0006] The output end of the angle adjustment motor is connected to the backrest rotating shaft. The transmission shaft is rotatably connected to the follower reverse gear. The outer wall of the backrest rotating shaft is provided with a first gear, and the outer wall of the transmission shaft is provided with a second gear. The transmission chain is sleeved on the outside of the first gear and the second gear and meshes with the first gear and the second gear. The follower reverse gear is fixedly connected to the armrest frame.

[0007] Preferably, it also includes a seat backrest, the seat backrest being driven by the angle adjustment motor to adjust the angle.

[0008] Preferably, the seat back includes two oppositely distributed backrest frame side plates, the angle adjustment motor is fixedly mounted on the inner side of one of the backrest frame side plates, and the armrest frame is mounted on the other backrest frame side plate.

[0009] Preferably, the follower reverse gear is rotatably connected to the backrest frame side plate.

[0010] Preferably, the backrest frame side plate is provided with a rotating gear, and the rotating gear is fixedly connected to the backrest shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The follow-up armrest leveling mechanism ensures that the armrest frame remains horizontal during seat back angle adjustment, providing passengers with good elbow support and improving comfort. Specifically, the armrest frame angle adjustment and seat back angle adjustment share the same angle adjustment motor, ensuring that the armrest frame works simultaneously with the seat back. This guarantees that the transmission ratio and rotation time between the armrest frame rotation and the seat back rotation shaft are the same, effectively ensuring that the horizontal position of the armrest frame does not shift. This follow-up armrest leveling mechanism has a compact structure and small size, making it easy to fit into most car seat frames, thus greatly improving its applicability. At the same time, it eliminates the need for a dedicated armrest leveling drive component, thereby significantly reducing hardware costs. Attached Figure Description

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a follow-up armrest horizontal mechanism for a car seat, including an angle adjustment motor 1, a backrest rotating shaft 2, a transmission chain 3, a transmission shaft 4, a follow-up reverse gear 5, and an armrest frame 6; the output end of the angle adjustment motor 1 is connected to the backrest rotating shaft 2, the transmission shaft 4 and the follow-up reverse gear 5 are rotatably connected, the outer wall of the backrest rotating shaft 2 is provided with a first gear 7, the outer wall of the transmission shaft 4 is provided with a second gear 8, the transmission chain 3 is sleeved on the outside of the first gear 7 and the second gear 8 and meshes with the first gear 7 and the second gear 8, and the follow-up reverse gear 5 and the armrest frame 6 are fixedly connected.

[0026] For further details, please refer to Figure 3 The backrest frame side plate 10 is provided with a rotating gear 11, which is fixedly connected to the backrest rotating shaft 2.

[0027] In this embodiment, the follow-up armrest horizontal mechanism is set in the frame of the car seat back 9. Its core includes an angle adjustment motor 1, a backrest rotating shaft 2, a transmission chain 3, a transmission shaft 4, a follow-up reverse gear 5, and an armrest frame 6. The backrest rotating shaft 2 is fixedly connected to the first gear 7, the transmission shaft 4 is rotatably connected to the follow-up reverse gear 5, the transmission shaft 4 is fixedly connected to the second gear 8, and the follow-up reverse gear 5 is fixedly connected to the armrest frame 6.

[0028] The backrest pivot 2 is connected to the backrest frame side plate 10 via a rotating gear 11. The angle adjustment motor 1 rotates in the opposite direction, causing the rotating gear 11 to rotate in the reverse direction, thereby realizing the rearward rotation of the seat back 9 (see appendix). Figure 5 As shown), the rotating gear 11 and the following reverse gear 5 are the same size, which ensures that the downward reversing angle adjustment of the armrest frame 6 is consistent with the backward reversing angle adjustment of the seat back 9.

[0029] When the car seat is in its initial position, the armrest frame 6 remains horizontal relative to the horizontal plane. When the angle of the seat back 9 needs to be adjusted backward, the angle adjustment motor 1 rotates in the reverse direction, causing the seat back 9 to rotate backward. At this time, the angle adjustment motor 1 reverses, causing the backrest shaft 2 to reverse. After the backrest shaft 2 reverses, it drives the transmission chain 3 to reverse through the first gear 7. After the transmission chain 3 reverses, it drives the follower reverse gear 5 to rotate forward through the second gear 8 and the transmission shaft 4. The follower reverse gear 5 rotates forward, causing the armrest frame 6 to rotate forward (see reference). Figure 5 (the downward rotation) thus makes the armrest frame 6 remain horizontal relative to the horizontal plane again;

[0030] This embodiment uses a follow-up armrest leveling mechanism to ensure that the armrest frame 6 remains horizontal during the angle adjustment of the seat back 9, providing good elbow support for passengers and improving comfort. Specifically, the armrest frame 6 and the seat back 9 share the same angle adjustment motor 1 to ensure that the armrest frame 6 works simultaneously with the seat back 9. This ensures that the transmission ratio between the rotation of the armrest frame 6 and the rotation of the seat back 9 shaft are the same, and the rotation time of the shaft is also the same, effectively ensuring that the horizontal position of the armrest frame 6 does not shift. This follow-up armrest leveling mechanism has a compact structure and small size, making it easy to adapt to most car seat frames, thus greatly improving its applicability. At the same time, it eliminates the need for a dedicated armrest leveling drive component, thereby achieving a significant reduction in hardware costs.

[0031] For further details, please refer to Figure 2 It also includes a seat backrest 9, which is driven by an angle adjustment motor 1 to adjust its angle.

[0032] In this embodiment, the backrest pivot 2 is connected to the backrest frame side plate 10 via a rotating gear 11. The angle adjustment motor 1 rotates in the opposite direction, causing the rotating gear 11 to rotate in the reverse direction, thereby realizing the rearward rotation of the seat back 9 (see Appendix). Figure 5 (As shown).

[0033] For further details, please refer to Figure 1 and Figure 2The seat back 9 includes two oppositely distributed backrest frame side plates 10. An angle adjustment motor 1 is fixedly installed on the inside of one backrest frame side plate 10, and the armrest frame 6 is installed on the other backrest frame side plate 10.

[0034] In this embodiment, the angle adjustment motor 1 is shared by the armrest frame 6 and the seat back 9 to ensure that the armrest frame 6 works at the same time as the seat back 9. This ensures that the transmission ratio between the rotation of the armrest frame 6 and the rotation of the seat back 9 shaft is the same, and the rotation time of the shaft is also the same, effectively ensuring that the horizontal position of the armrest frame 6 does not shift.

[0035] The working principle and usage process of this utility model are as follows: When the car seat is in its initial position, the armrest frame 6 remains horizontal relative to the horizontal plane. When the angle of the seat back 9 needs to be adjusted backward, the angle adjustment motor 1 rotates in the reverse direction, causing the seat back 9 to rotate backward. At this time, the angle adjustment motor 1 reverses, causing the backrest shaft 2 to reverse. After the backrest shaft 2 reverses, it drives the transmission chain 3 to reverse through the first gear 7. After the transmission chain 3 reverses, it drives the follower reverse gear 5 to rotate forward through the second gear 8 and the transmission shaft 4. The follower reverse gear 5 rotates forward, causing the armrest frame 6 to rotate forward (see reference). Figure 5 (The downward rotation) causes the handrail frame 6 to remain horizontal relative to the horizontal plane again.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
