Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a multifunctional automotive seat. Background Technology

[0002] Car seats are becoming increasingly versatile. For example, some car seats are equipped with a one-touch bed function. Some can be converted into a sleeping bed by removing the headrests of the second-row seats and folding the backrests back flat to connect with the third-row seats; some can be converted into a sleeping bed by folding both the second and third-row seats forward; some can be converted into a sleeping bed by folding the backrests of the third-row seats; some can be converted into a sleeping bed by rotating the second-row seats and unfolding the third-row seats; and some can be converted into a sleeping bed by reclining the backrests and unfolding the leg rests to a completely flat position.

[0003] Some car seats are equipped with forward-facing and rear-facing modes. Some use a rotating dial to switch between forward-facing and rear-facing modes, while others achieve this by folding the entire car seat back 90 degrees and swapping the backrest and seat cushion.

[0004] However, existing car seats are difficult to simultaneously accommodate forward-facing, rear-facing, and sleeping modes. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a multi-functional car seat that simultaneously takes into account forward-facing seating mode, reverse-facing seating mode, forward-facing bed mode and reverse-facing bed mode.

[0006] The technical solution adopted by this utility model to solve its technical problem is to propose a multifunctional car seat, comprising:

[0007] A backrest module, installed on the vehicle body, includes a lower support, an upper support, and a backrest body arranged sequentially from bottom to top. The upper support is rotatably mounted on the lower support, and the backrest body is rotatably mounted on the upper support.

[0008] The slide rail and seat cushion module are provided. The slide rail is installed on the vehicle body and the seat cushion module is installed on the slide rail and can slide back and forth along the slide rail. The front and rear sides of the seat cushion module are respectively provided with front leg rests and rear leg rests, and the front leg rests and rear leg rests can be extended outward from the seat cushion module and folded into the seat cushion module.

[0009] The seat cushion module moves along the slide rail to the front of the backrest module, thereby switching the car seat to a forward-facing seating mode.

[0010] In forward-facing seating mode, the backrest and the upper support fold backward, and the front leg rest and the rear leg rest unfold outward, so that the car seat switches to forward-facing bed mode.

[0011] The seat cushion module moves along the slide rail to the rear of the backrest module, thereby switching the car seat to a rear-facing mode.

[0012] In the reverse seating mode, the backrest and the upper support flip forward, and the front leg rest and the rear leg rest unfold outward, so that the car seat switches to the reverse bed mode.

[0013] Furthermore, a first angle adjuster is provided between the backrest body and the upper support, and a first drive motor is provided on the backrest body. The first drive motor drives the backrest body to rotate relative to the upper support through the first angle adjuster.

[0014] Furthermore, an upper bracket is provided on each of the left and right sides of the backrest body, and a first angle adjuster is provided between each of the two upper brackets and the backrest body.

[0015] The output end of the first drive motor is equipped with a backrest rotating shaft, and the two ends of the backrest rotating shaft are respectively connected to the two first angle adjusters.

[0016] Furthermore, the lower support is provided with a second drive motor, the output shaft of the second drive motor is provided with a gear, the upper support is provided with a toothed plate, the toothed plate meshes with the gear, and the second drive motor drives the upper support to rotate relative to the lower support through the gear and the toothed plate.

[0017] Furthermore, the toothed plate is provided with an arc-shaped groove, the center of which coincides with the rotation center of the upper support;

[0018] The lower support is provided with a limiting pin, which passes through the arc-shaped groove and can limit the rotation angle of the toothed plate.

[0019] Furthermore, each side of the backrest module is provided with a lower bracket, and the two upper brackets are rotatably mounted on the two lower brackets respectively;

[0020] A second angle adjuster is provided between one of the lower supports and one of the upper supports, and another second angle adjuster is provided between another lower support and another upper support.

[0021] Furthermore, when the car seat is in the forward-facing bed mode, the front leg rest, the seat cushion module, the rear leg rest, and the backrest are aligned in sequence.

[0022] When the car seat is in the reverse bed mode, the rear leg rest, the seat cushion module, the front leg rest, and the backrest are aligned in sequence.

[0023] Furthermore, the lower bracket is fixedly mounted on the vehicle body.

[0024] Furthermore, the front leg rest and the rear leg rest are respectively connected to the front and rear sides of the seat cushion module via a linkage mechanism;

[0025] The seat cushion module is equipped with a third drive motor, which is connected to the linkage mechanism. The third drive motor drives the front leg support or the rear leg support to switch between an unfolded state and a folded state through the linkage mechanism.

[0026] Furthermore, the slide rail is configured as an electric slide rail.

[0027] Compared with the prior art, the present invention has at least the following beneficial effects:

[0028] In this invention, the backrest module includes a lower support, an upper support, and a backrest body. The upper support is rotatably mounted on the lower support, and the backrest body is rotatably mounted on the upper support, ensuring that the backrest body can move to different postures when the car seat switches between different modes. When the seat cushion module moves along the slide rail to the front of the backrest module, the car seat can be switched to a forward-facing sitting mode. In the forward-facing sitting mode, by continuing to tilt the backrest body and upper support backward and unfolding the front and rear leg rests, the car seat can be switched to a forward-facing bed mode. When the seat cushion module moves along the slide rail to the rear of the backrest module, the car seat can be switched to a rear-facing sitting mode. In the rear-facing sitting mode, by continuing to tilt the backrest body and upper support forward and unfolding the front and rear leg rests, the car seat can be switched to a rear-facing bed mode. This car seat can accommodate forward-facing, rear-facing, forward-facing bed, and rear-facing bed modes without the need for other seats, thus diversifying the scenarios, enhancing practicality and flexibility. Furthermore, the car seat is easy to operate when switching between different modes, and its space utilization is high.

[0029] In this invention, the first drive motor drives the backrest body to rotate relative to the upper support through the first angle adjuster, and the second drive motor drives the upper support to rotate relative to the lower support through gears and gear plates. The structure is simple, the movement is smooth, and the synchronization is good.

[0030] In this invention, regardless of whether the bed is positioned facing forward or backward, the upper surfaces of the front leg rest, seat cushion module, rear leg rest, and backrest are all flush, which can effectively ensure the comfort of the passenger when lying down.

[0047] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0048] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0049] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0050] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0051] like Figures 1-9 As shown, a multifunctional car seat in this embodiment mainly includes: a backrest module 1, a slide rail 2, a seat cushion module 3, a front leg rest 4, and a rear leg rest 5. Among them,

[0052] The backrest module 1 is installed on the vehicle body. The backrest module 1 includes a lower bracket 12, an upper bracket 11 and a backrest body 10 arranged sequentially from bottom to top. The upper bracket 11 is rotatably mounted on the lower bracket 12 and the backrest body 10 is rotatably mounted on the upper bracket 11. Specifically, the lower bracket 12 can be detachably and fixedly connected to the vehicle body by, but is not limited to, multiple bolts, and does not require any action during use.

[0053] The slide rail 2 is installed in the vehicle body. In this embodiment, the slide rail 2 is configured as an electric slide rail, which drives the seat cushion module 3 to slide back and forth for easy adjustment. Since the electric slide rail structure is a conventional structure and existing technology in existing car seats, it will not be described in detail here.

[0054] The seat cushion module 3 is mounted on the slide rail 2 and can slide back and forth along the slide rail 2. Specifically, the seat cushion module 3 is mounted on the upper slide rail of the electric slide rail. The electric slide rail drives the upper slide rail to slide along the lower slide rail, thereby causing the seat cushion module 3 to slide along the lower slide rail, i.e., to move back and forth. The front leg support 4 and the rear leg support 5 are respectively provided on the front and rear sides of the seat cushion module 3. Both the front leg support 4 and the rear leg support 5 can be extended outward from the seat cushion module 3 and folded into the seat cushion module 3. Specifically, the front leg support 4 can be extended forward relative to the seat cushion module 3, and the rear leg support 5 can be extended backward relative to the seat cushion module 3. When the front leg support 4 and the rear leg support 5 are folded into the front and rear sides of the seat cushion module 3, there is no outward protrusion, ensuring that no extra space is occupied.

[0055] When the seat cushion module 3 moves along the slide rail 2 to the front of the backrest module 1, the car seat switches to a forward-facing seating mode (e.g., Figure 1 and Figure 2 As shown in the image, the passenger can sit facing forward in the car seat, which is the normal usage mode of the car seat.

[0056] When the car seat is in forward-facing seating mode, the backrest body 10 and upper support 11 are folded back, and the front leg rest 4 and rear leg rest 5 are extended outwards, thus switching the car seat to a forward-facing bed mode (e.g., Figure 4 (As shown), at this time the passenger can lie down on the car seat.

[0057] When the car seat is in forward-facing mode, the seat cushion module 3 moves along the slide rail 2 to the rear of the backrest module 1. Correspondingly, the backrest needs to rotate slightly forward to switch the car seat to rear-facing mode (e.g., ...). Figure 3 As shown in the image, passengers can sit in the car seat facing backwards. In both the forward and backward seating modes, the car seats are arranged in a nearly symmetrical front-to-back configuration.

[0058] When the car seat is in rear-facing mode, the backrest body 10 and upper support 11 are folded forward, and the front leg rest 4 and rear leg rest 5 are extended outwards, thus switching the car seat to a rear-facing bed mode (e.g., Figure 5 (As shown), at this time the passenger can lie down on the car seat.

[0059] When the car seat is in forward-facing bed mode, the front leg rest 4, seat cushion module 3, rear leg rest 5, and backrest are aligned in sequence. When the car seat is in reverse-facing bed mode, the rear leg rest 5, seat cushion module 3, front leg rest 4, and backrest are aligned in sequence. Whether in forward-facing or reverse-facing bed mode, the upper surfaces of the front leg rest 4, seat cushion module 3, rear leg rest 5, and backrest are aligned, ensuring passenger comfort when lying down in the car seat.

[0060] In actual use, the backrest module 1 of this embodiment includes a lower support 12, an upper support 11, and a backrest body 10. The upper support 11 is rotatably mounted on the lower support 12, and the backrest body 10 is rotatably mounted on the upper support 11, ensuring that the backrest body 10 can move to various postures when the car seat switches between different modes. When the seat cushion module 3 moves along the slide rail 2 to the front of the backrest module 1, the car seat can be switched to the forward-facing sitting mode. In the forward-facing sitting mode, by continuing to tilt the backrest body 10 and the upper support 11 backward and unfolding the front leg rest 4 and the rear leg rest 5, the car seat can be switched to the forward-facing bed mode. When the seat cushion module 3 moves along the slide rail 2 to the rear of the backrest module 1, the car seat can be switched to the reverse-facing sitting mode. In the reverse-facing sitting mode, by continuing to tilt the backrest body 10 and the upper support 11 forward and unfolding the front leg rest 4 and the rear leg rest 5, the car seat can be switched to the reverse-facing bed mode. This car seat can accommodate forward-facing, rear-facing, forward-facing bed, and rear-facing bed modes without the need for other seats, thus diversifying the scenarios, enhancing practicality and flexibility. Furthermore, the car seat is easy to operate when switching between different modes, and its space utilization is high.

[0061] Specifically, in this embodiment, a first angle adjuster 102 is provided between the backrest body 10 and the upper support 11, and a first drive motor 101 is provided on the backrest body 10. The first drive motor 101 drives the backrest body 10 to rotate relative to the upper support 11 through the first angle adjuster 102. Further, an upper support 11 is provided on each of the left and right sides of the backrest body 10, and a first angle adjuster 102 is provided between each of the two upper supports 11 and the backrest body 10. A backrest rotating shaft 100 is configured at the output end of the first drive motor 101, and both ends of the backrest rotating shaft 100 are respectively connected to the two first angle adjusters 102. In actual use, the first drive motor 101 drives the backrest rotating shaft 100 to rotate, and the backrest rotating shaft 100 simultaneously drives the first angle adjusters 102 at its left and right ends, causing the backrest body 10 to rotate relative to the upper support 11.

[0062] More specifically, the lower support 12 is provided with a second drive motor 111, which is detachably and fixedly connected to the lower support 12. The output shaft of the second drive motor 111 is provided with a gear 111A, which drives the gear 111A to rotate through the output shaft. The upper support 11 is provided with a toothed plate 113, which is fixedly connected to the upper support 11 or integrally formed with the upper support 11. The toothed plate 113 meshes with the gear 111A. In actual use, the second drive motor 111 drives the output shaft to rotate, and drives the upper support 11 to rotate relative to the lower support 12 through the gear 111A and the toothed plate 113.

[0063] A lower bracket 12 is provided on each side of the backrest module 1, and two upper brackets 11 are rotatably mounted on the two lower brackets 12. A second angle adjuster 112 is provided between one lower bracket 12 and one upper bracket 11, and another second angle adjuster 112 is provided between the other lower bracket 12 and the other upper bracket 11, to ensure that the two upper brackets 11 rotate smoothly relative to the two lower brackets 12.

[0064] The toothed plate 113 has an arc-shaped groove 113A, the center of which coincides with the rotation center of the upper support 11. The lower support 12 has a limiting pin 114, which passes through the arc-shaped groove 113A and limits the rotation angle of the toothed plate 113. When the second drive motor 111 drives the gear 111A to rotate, and the gear 111A meshes with the toothed plate 113 to rotate, causing the upper support 11 to rotate, the limiting pin 114 remains stationary while the toothed plate 113 rotates. Therefore, the relative position of the limiting pin 114 in the arc-shaped groove 113A changes. When the end of the arc-shaped groove 113A abuts against the limiting pin 114, the toothed plate 113 is prevented from continuing to rotate, thereby limiting the rotation angle of the toothed plate 113.

[0065] In actual use, the first drive motor 101 drives the backrest body 10 to rotate relative to the upper support 11 through the first angle adjuster 102, and the second drive motor 111 drives the upper support 11 to rotate relative to the lower support 12 through the gear 111A and the gear plate 113. The structure is simple, the movement is smooth, and the synchronization is good.

[0066] In this embodiment, the front leg support 4 and the rear leg support 5 are respectively connected to the front and rear sides of the seat cushion module 3 via a linkage mechanism 450. The seat cushion module 3 is equipped with a third drive motor 451, which is connected to the linkage mechanism 450. The third drive motor 451 drives the front leg support 4 or the rear leg support 5 to switch between an unfolded state and a folded state via the linkage mechanism 450. The linkage mechanism 450 of the front leg support 4 and the linkage mechanism 450 of the rear leg support 5 are driven by different third drive motors 451.

[0067] It should be explained that since the linkage mechanism 450 can be the existing six-way or four-way leg support linkage mechanism 450 of the car seat, which belongs to the prior art, it will not be described in detail here. For example, it can adopt the six-bar linkage mechanism in CN221698553U, the leg support transmission mechanism in CN120439907A, and the leg support mechanism linkage assembly in CN222629175U, etc.

[0068] In actual use, under normal conditions, the car seat is in the forward-facing seating mode. When it is necessary to switch the car seat from the forward-facing seating mode to the forward-facing bed mode, the electric slide rail drives the seat cushion module 3 forward by approximately 200 mm, the first drive motor 101 drives the first adjuster 102 to rotate forward by approximately 23 degrees, then the second drive motor 111 drives the second adjuster 112 to rotate backward by approximately 90 degrees, and the third drive motor 451 drives the linkage mechanism 450, causing the front leg rest 4 and the rear leg rest 5 to unfold forward and backward respectively, thus switching the car seat to the forward-facing bed mode. When it is necessary to switch the car seat from the forward-facing seating mode to the rear-facing seating mode, the electric slide rail drives the seat cushion module 3 to slide backward by approximately 678 mm, the first drive motor 101 drives the first adjuster 102 to rotate forward by approximately 46 degrees, thus switching the car seat to the rear-facing seating mode. When the car seat needs to be switched from forward-facing sitting mode to rear-facing bed mode, the electric slide rail drives the seat cushion module 3 to slide backward by about 878 mm, the first drive motor 101 drives the first adjuster 102 to rotate forward by about 23 degrees, then the second drive motor 111 drives the second adjuster 112 to rotate backward by about 90 degrees, and the third drive motor 451 drives the linkage mechanism 450 to unfold the front leg rest 4 and the rear leg rest 5 forward and backward respectively, so that the car seat is switched to rear-facing bed mode.

[0069] In this solution, the car seat itself can accommodate forward-facing, rear-facing, forward-facing bed, and rear-facing bed modes without the need for other seats, thus achieving versatility and enhancing practicality and flexibility. Moreover, the car seat is easy to operate when switching between modes, and its space utilization is high.
