Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to an automotive seat with a reclining function that can be converted into a bed. Background Technology

[0002] With the continuous development of the automotive industry and people's increasing demands for travel comfort, the function and design of car seats are constantly being innovated and improved. In scenarios such as long-distance travel and road trips, passengers' need for a more comfortable resting space inside the car is becoming increasingly urgent. Car seats with the function of reclining into a bed have emerged. This function allows the seat back to flip back and lie flat, combining with the seat cushion and other components to form a bed-like surface, providing passengers with a more comfortable resting environment.

[0003] However, existing car seats with reclining bed functionality still face some technical challenges in practical applications. Due to the limitations of the car body structure, the rear sidewalls of some car bodies typically protrude inwards by a certain distance. When the car seat backrest frame flips backward, the side edge of the backrest frame inevitably interferes with the sidewall of the car body. This interference prevents the backrest frame from flipping further backward, preventing it from fully flattening and thus failing to achieve the ideal reclining bed mode. This limits the effectiveness of the function in actual use and the user experience. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention aims to provide a car seat with a reclining function to solve the problem that the backrest frame of the traditional car seat interferes with the side wall of the car body when it is flipped backward, and cannot be fully flat to form a comfortable resting space.

[0005] To achieve the above objectives, this utility model proposes a car seat with a reclining bed function, including a backrest frame and a seat cushion frame. The backrest frame can be flipped forward or backward relative to the seat cushion frame. The backrest frame includes an independently flippable main frame and a side wing frame. The side wing frame is located on the side of the main frame near the side wall of the vehicle body. A first locking mechanism is provided between the main frame and the side wing frame. A second locking mechanism is provided between the side wing frame and the side wall of the vehicle body. The second locking mechanism includes a vehicle body bolt fixed to the side wall of the vehicle body and a side wing lock body fixed to the side wing frame.

[0006] When the backrest frame is in the initial position, the first locking mechanism is in the locked state, the main frame is connected to the side wing frame side by side through the first locking mechanism, the second locking mechanism is in the unlocked state, and the side wing frame is located in front of the vehicle body bolt; when the backrest frame flips backward so that the side wing lock body on it is side by side with the vehicle body bolt, the second locking mechanism can automatically lock, the first locking mechanism can automatically unlock, and the main frame can continue to flip backward relative to the side wing frame until it is flattened to form a reclining bed mode.

[0007] In the above scheme: both the first and second locking mechanisms are equipped with unlocking mechanisms, which are cable motors. Each of the two cable motors is controlled by a microswitch. When the side wing lock body moves backward to be parallel with the body bolt, the corresponding microswitch controls the second locking mechanism to automatically lock, achieving the locking of the side wing lock body to the body bolt. Simultaneously, another microswitch controls the first locking mechanism to automatically unlock. Conversely, during the process of the backrest frame returning from its flattened state, when the side wing lock body moves forward to be parallel with the body bolt, the corresponding microswitch controls the first locking mechanism to automatically lock, while another microswitch controls the second locking mechanism to automatically unlock. This design automates the locking and unlocking during the backrest frame's flipping process. This automated control method avoids the tediousness of manual operation by the user, greatly improving the convenience and efficiency of operation.

[0008] The above solution also includes a slide rail assembly. The bottom of the backrest frame is rotatably connected to the slide rail assembly via an angle adjuster. The seat cushion frame is mounted above the slide rail assembly via a lifting mechanism, and its front end is rotatably connected to a leg support mechanism. The leg support mechanism is folded under the seat cushion frame via a leg support storage mechanism. When the main frame is folded back, the seat cushion frame can be raised to be flush with the main frame via the lifting mechanism, and the leg support mechanism can be folded forward to be flush with the seat cushion frame via the leg support storage mechanism. This makes the main frame, seat cushion frame, and leg support mechanism all horizontal, providing a more comfortable resting environment for passengers. Specifically, both the lifting mechanism and the leg support storage mechanism are combined structures of a linkage and a lead screw motor, which is existing technology.

[0009] In the above solution: the car seat is a rear seat, including two independently rotatable 40 / 60 split backrest frames. Each backrest frame consists of a main frame and side wing frames, with the two main frames adjacent to each other and the side wing frames located on the outer side of the two main frames. This utility model is particularly suitable for rear seats. The above design allows the rear seats to form a larger resting space when folded down, improving the utilization rate of the vehicle's interior space.

[0010] In the above solution: the bottom two ends of the backrest frame are respectively installed on the slide rail assembly by fixed brackets, the fixed brackets and the slide rail assembly are fixed by bolts, and the backrest frame and the fixed brackets are rotatably connected by the angle adjuster. The structure is simple and the assembly is convenient.

[0011] In the above scheme: the first locking mechanism includes a middle locking body fixed on the main frame and a middle locking bolt fixed on the side wing frame, or a middle locking bolt fixed on the main frame and a middle locking body fixed on the side wing frame. The installation can be flexibly selected according to actual design requirements, which improves the flexibility of seat design.

[0012] In the above solution: the intermediate bolt is equipped with a folding and storage mechanism. When the first locking mechanism is in the unlocked state, the intermediate bolt can be folded down from its perpendicular position to the side frame to a stored state via the folding and storage mechanism. When the main frame returns to its original position, the intermediate bolt can automatically open when the first locking mechanism needs to lock. This is existing technology. Specifically, the opening and closing of the intermediate bolt can be achieved by establishing a linkage mechanism between the cable and the flipping angle of the main frame.

[0013] The beneficial effects of this utility model are as follows: 1. By adopting a split design, the backrest frame is divided into a main frame and a side frame, with a first locking mechanism between the two and a second locking mechanism between the side frame and the vehicle side wall, thus realizing the segmented flipping of the backrest frame. When the backrest frame flips backward until the side lock body is parallel to the vehicle body bolt, the second locking mechanism automatically locks, and the first locking mechanism automatically unlocks. The main frame can continue to flip backward relative to the side frame until it is flattened to form a reclining bed mode. This design effectively avoids interference between the side end of the backrest frame and the vehicle side wall, allowing the backrest frame to be completely flattened. 2. Compared with traditional complex mechanical structures, the seat design of this utility model is simpler and more efficient, helping to reduce manufacturing costs and improve production efficiency.

[0022] like Figure 1 As shown in Figure 8, a car seat with a reclining function is mainly composed of a backrest frame 1 and a seat cushion frame 2. The backrest frame 1 can be flipped forward or backward relative to the seat cushion frame 2.

[0023] The backrest frame 1 adopts a split design, including an independently flip-up main frame 11 and a side wing frame 12. The side wing frame 12 is located on the side of the main frame 11 near the side wall of the vehicle body. A first locking mechanism 3 is provided between the main frame 11 and the side wing frame 12, and a second locking mechanism is provided between the side wing frame 12 and the side wall of the vehicle body. The second locking mechanism includes a vehicle body bolt 4 fixed to the side wall of the vehicle body and a side wing lock body 5 fixed to the side wing frame 12.

[0024] When the backrest frame 1 is in its initial position, the first locking mechanism 3 is locked, and the main frame 11 is connected to the side wing frame 12 side-by-side via the first locking mechanism 3. The second locking mechanism is unlocked, and the side wing frame 12 is located in front of the body lock bolt 4. When the backrest frame 1 flips backward until the side wing lock body 5 is parallel to the body lock bolt 4, the second locking mechanism automatically locks, the first locking mechanism 3 automatically unlocks, and the main frame 11 can continue to flip backward relative to the side wing frame 12 until it is flattened to form a reclining bed mode.

[0025] This design effectively avoids interference between the side end of the backrest frame 1 and the side wall of the vehicle body (the side wall at the rear of the vehicle body usually protrudes inward by a certain distance, and the vehicle body bolt 4 is fixed to the front of the protruding section), allowing the backrest frame 1 to be laid completely flat.

[0026] Ideally, both the first locking mechanism 3 and the second locking mechanism are equipped with unlocking mechanisms, which are cable motors 6. Each cable motor 6 is controlled by a microswitch. When the side wing lock body 5 moves backward to be parallel with the body bolt 4, the corresponding microswitch controls the second locking mechanism to automatically lock, thus locking the side wing lock body 5 to the body bolt 4. Simultaneously, another microswitch controls the first locking mechanism 3 to automatically unlock. Conversely, during the return process of the backrest frame 1 from its flattened state, when the side wing lock body 5 moves forward to be parallel with the body bolt 4, the corresponding microswitch controls the first locking mechanism 3 to automatically lock, while another microswitch controls the second locking mechanism to automatically unlock. This design automates the locking and unlocking during the flipping process of the backrest frame 1. This automated control method avoids the tediousness of manual operation by the user, greatly improving the convenience and efficiency of operation.

[0027] Ideally, it also includes a slide rail assembly 7. The bottom of the backrest frame 1 is rotatably connected to the slide rail assembly 7 via an angle adjuster. The seat cushion frame 2 is mounted above the slide rail assembly 7 via a lifting mechanism, and its front end is rotatably connected to a leg support mechanism 8. The leg support mechanism 8 is folded under the seat cushion frame 2 via a leg support storage mechanism. When the main frame 11 is folded backward, the seat cushion frame 2 can be raised upward to be flush with the main frame 11 via the lifting mechanism, and the leg support mechanism 8 can be folded forward to be flush with the seat cushion frame 2 via the leg support storage mechanism. This makes the main frame 11, seat cushion frame 2, and leg support mechanism 8 all horizontal, providing a more comfortable resting environment for passengers. Specifically, both the lifting mechanism and the leg support storage mechanism are combined structures of a linkage and a lead screw motor, which is existing technology.

[0028] Ideally, the car seat is a rear seat, comprising two independently rotatable 40 / 60 split backrest frames 1. Each backrest frame 1 consists of a main frame 11 and side wing frames 12, with the two main frames 11 adjacent to each other and the side wing frames 12 located on the outer side of each main frame 11. This invention is particularly suitable for rear seats, and the above design allows the rear seats to be folded flat to form a larger resting space, improving the utilization of the vehicle's interior space.

[0029] Ideally, the bottom ends of the backrest frame 1 are respectively mounted on the slide rail assembly 7 via fixed brackets 9. The fixed brackets 9 and the slide rail assembly 7 are fixed with bolts. The backrest frame 1 and the fixed brackets 9 are rotatably connected by an angle adjuster. The structure is simple and the assembly is convenient.

[0030] Preferably, the first locking mechanism 3 includes an intermediate locking body fixed to the main frame 11 and an intermediate locking bolt fixed to the side wing frame 12, or an intermediate locking bolt fixed to the main frame 11 and an intermediate locking body fixed to the side wing frame 12. The installation can be flexibly selected according to actual design requirements, which improves the flexibility of seat design.

[0031] Ideally, the intermediate bolt is equipped with a folding and storage mechanism. When the first locking mechanism 3 is in the unlocked state, the intermediate bolt can be folded down from its position perpendicular to the side frame 12 to its stored state via the folding and storage mechanism. When the main frame 11 returns to its original position, the intermediate bolt can automatically open when the first locking mechanism 3 needs to be locked. This is existing technology. Specifically, the opening and closing of the intermediate bolt can be achieved by establishing a linkage mechanism between the cable and the flipping angle of the main frame 11.
