[0002] Currently, the small tables attached to the back of car seats are usually fixed when unfolded, and their length cannot be adjusted according to usage needs, resulting in limited placement area and difficulty in adapting to the usage habits and space requirements of different users. Although drawer-style tables with adjustable length functions have appeared on the market, these structures generally suffer from problems such as complex design and large thickness, which not only increases manufacturing costs and assembly difficulty, but also affects the actual user experience. Utility Model Content

[0003] This application provides a backrest table, a seat back, and a car seat, which can improve the user experience and at least partially solve the above-mentioned technical problems.

[0004] To achieve the above objectives, according to a first aspect of this application, a backrest table is provided, comprising a first plate and a second plate, the first plate having a receiving groove, the second plate being rotatably disposed within the receiving groove, the second plate being configured such that when the second plate is rotated out of the receiving groove to a first position, the first surface of the second plate is flush with the inner bottom wall of the receiving groove, and when the second plate is rotated in from outside the receiving groove to a second position, the second surface of the second plate is flush with the surface of the first plate.

[0008] Optionally, when the second plate is in the second position, the first plate surface of the second plate is directly opposite and in contact with the inner bottom wall of the receiving groove.

[0009] Optionally, the hinge portion is a damped hinge.

[0010] Optionally, the second plate has a notch at one end away from the hinge portion, the notch being for a user's finger to insert.

[0011] Optionally, the inner wall of the receiving groove away from the hinge portion is a first inclined surface, and the first inclined surface is inclined toward the side away from the hinge portion;

[0012] The end wall of the second plate away from the hinge portion is a second inclined surface, which is configured to fit against the first inclined surface.

[0013] Optionally, the first plate has a storage slot.

[0014] Optionally, the first plate includes a first shell, a second shell, and a frame, wherein the first shell and the second shell are snap-fitted together, and the frame is embedded between the first shell and the second shell.

[0015] According to a second aspect of this application, a seat back is provided, including the backrest table described in the first aspect.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0035] Firstly, this application provides a backrest table, please refer to... Figure 1 and Figure 2 The backrest table includes a first panel 1 and a second panel 2. The first panel 1 has a receiving groove 11 that opens outwards. The receiving groove 11 is used to store the second panel 2 when not in use. The second panel 2 is rotatably disposed at one end inside the receiving groove 11 and rotates around the disposed part so that it can be rotated out of the receiving groove 11 and rotated to a first position during use.

[0036] Furthermore, the second plate 2 has at least a first position and a second position during use. In the first position, the first plate surface 21 of the second plate 2 is flush with the inner bottom wall surface of the receiving groove 11, thereby forming an integrated plate structure together with the outer surface of the first plate 1 on one side of the receiving groove 11 and the inner bottom wall of the receiving groove 11, providing a large usable placement area to meet the user's needs for table width during use.

[0037] When not in use, the second panel 2 can rotate from the first position to the second position and be completely stored in the receiving slot 11, so that the second panel 22 of the second panel 2 is flush with the surface of the first panel 1, thereby ensuring the consistency and flatness of the table appearance. This makes the entire backrest table present a simple and regular structural appearance when not in use, which is beneficial to the overall coordination of the vehicle cabin space.

[0038] Furthermore, since the second panel 2 is a flip-up structure, it has advantages over traditional drawer-type structures in terms of simple structure, easier thickness control, and fewer parts, thereby reducing manufacturing costs and assembly difficulty to a certain extent. To further avoid structural ambiguity, the receiving groove 11 refers to a recessed area within the first panel 1 that can accommodate the second panel 2, with its opening facing the outer surface of the tabletop; the second panel 2 being rotatably configured means that one end of the second panel 2 is connected to one end of the receiving groove 11 via a pin, hinge, or other rotating structure, allowing it to rotate around this connection point between the inside and outside of the receiving groove 11. The first panel surface 21 and the second panel surface 22 are two opposing surfaces of the second panel 2, and which side is designated as the first or second panel surface 22 can be determined according to the design direction. The overall structure does not rely on complex slide rails or support structures, which is beneficial to improving the reliability of the backrest tabletop and, to a certain extent, enhances the flexibility and ease of operation of tabletop area adjustment. Through the above structural and functional configuration, a tabletop solution with length extension function is provided while maintaining the compact shape of the backrest tabletop, possessing certain promotional and application value.

[0039] In some embodiments, combined with Figure 1 , Figure 2 To achieve a rotatable connection between the second plate 2 and the first plate 1, so that the second plate 2 can be rotated out of the receiving groove 11 during use and rotated into the receiving groove 11 when not in use, the backrest table also includes a rotating member 3. The rotating member 3 is located between the first plate 1 and the second plate 2 and is used to achieve a rotational engagement between the two.

[0040] Specifically, the rotating member 3 includes a hinge portion 31, with a first end connected to the end of the first plate 1 and a second end connected to the end of the second plate 2, thereby constructing a rotating structure in which the second plate 2 can rotate relative to the first plate 1 around the hinge portion 31.

[0041] It is understandable that the hinge part 31 adopts a damping hinge structure, which enables the second plate 2 to have a certain stability after rotating to any angle position. It can maintain its current posture in the air without relying on additional support structures. This hovering characteristic allows users to adjust the angle of the second plate 2 according to their needs during actual use, which is beneficial to improving the comfort and flexibility of use. Specifically, the hinge part 31 is provided with a damping component at the connection. The damping component can generate a braking effect through a built-in spring or hydraulic mechanism, thereby controlling the rotation speed of the second plate 2 and maintaining its balance at a specific angle. The setting of the rotating part 3 enables the second plate 2 to not only smoothly flip out of the receiving slot 11 and unfold for use, but also to maintain a certain angle adjustment capability in use, providing structural support for the unfolding function and stability of the second plate 2. The connection part 151 between the rotating part 3 and the first plate 1 and the second plate 2 can be processed and formed by screwing, snap-fitting or injection molding into an integrated connection method to meet the requirements of lightweight and low-cost assembly of the entire backrest table.

[0042] In this embodiment, the rotating component 3 is a mechanical part, and its material can be metal or high-strength engineering plastic. The center line of the rotating shaft is set in the edge area of ​​the receiving groove 11 near the opening side. Its positional relationship facilitates the second plate 2 to be flipped over and joined flush with the bottom surface of the receiving groove 11, thereby expanding the entire tabletop area. Through this structural configuration, the overall simplicity is maintained while enhancing the ease of operation during use.

[0043] In some examples, combined Figure 1 , Figure 2 After the second plate 2 is flipped to the first position by the rotating component 3, its end contacts the end of the first plate 1, forming a stop-and-hold fit. This structurally restricts the second plate 2 from continuing to rotate, which helps to ensure that the first plate surface 21 of the second plate 2 fits against the inner bottom wall surface of the receiving groove 11 in the same plane, thus making the entire tabletop a flat placement surface when unfolded for use. This stop-and-hold structure can be formed by a structural protrusion, a stepped structure, or directly by geometric contact of the plate end faces. The specific contact position is selected in the end edge area near the opening side of the receiving groove 11, making the rotation path more reasonably restricted.

[0044] Furthermore, to improve the flatness of the appearance after storage, when the second plate 2 is rotated to the second position, its first plate surface 21 fits snugly against the inner bottom wall of the receiving groove 11, while the second plate surface 22 of the second plate 2 is flush with the outer surface of the first plate 1. This structure allows the table surface to appear as a continuous and flat whole in the stored state, with a harmonious visual effect, and helps prevent structural protrusions from affecting the utilization of cabin space.

[0045] It can be understood that the inner bottom wall of the receiving groove 11 refers to the wall surface inside the first plate 1 that fits against the first plate surface 21 of the second plate 2 when accommodating the second plate 2. Its surface can be designed to be smooth or have slight positioning steps to increase fitting accuracy. The surface of the first plate 1 refers to the exposed surface on the side where the receiving groove 11 is located, forming the overall appearance of the backrest tabletop when the second plate 2 is fully retracted. Through the above structural design, the integration and stability of the tabletop surface can be guaranteed to a certain extent in both the unfolded and retracted states, improving user comfort and reducing the risk of malfunctions during use. It also facilitates mass production and precision control.

[0046] In some examples, such as Figure 1 , Figure 2 As shown, to further enhance the usability and structural compactness of the backrest tabletop, a notch 23 is provided at the end of the second panel 2 away from the hinge 31. This notch 23 is located on the edge of the second panel 2, and its size and position are suitable for the user's fingers to insert. Thus, when the second panel 2 is stored in the receiving slot 11, the user can easily flip the second panel 2 out of the receiving slot 11 through the notch 23, which improves the intuitiveness and comfort of actual operation. The notch 23 can be an arc-shaped or rectangular opening, and its edges are chamfered to reduce the risk of hand injury during operation.

[0047] For example, refer to Figure 2 , Figure 3 In order to further optimize the rotation trajectory of the second plate 2 and the fitting effect after storage, the inner wall of the receiving groove 11 away from the hinge part 31 is designed as a first inclined surface 111. The first inclined surface 111 is inclined towards the side away from the hinge part 31, so that the first inclined surface 111 will not interfere with the path of the second plate 2 during rotation, which is beneficial to ensuring the smoothness of the second plate 2 in and out of the receiving groove 11.

[0048] Meanwhile, the end wall of the second plate 2 away from the hinge part 31 is set as a second inclined surface 112. The inclination direction of the second inclined surface 112 is the same as that of the first inclined surface 111, and its inclination angle is designed to fit with the first inclined surface 111. When the second plate 2 is completely rotated into the receiving groove 11 to form the second position, the first inclined surface 111 and the second inclined surface 112 form a surface-fitting relationship, which strengthens the stability of the overall storage state from a structural point of view, and provides a more regular and continuous table surface visually, which is conducive to maintaining the integrated look of the cabin interior.

[0049] In addition, to improve the functionality and practicality of the backrest table, combined with Figure 4The first panel 1 is provided with a storage slot 12, which is located on the desktop area near the user and has a certain depth and opening width for temporarily placing mobile phones, tablets, or other portable items. The storage slot 12 can be formed by one-piece injection molding or post-processing. Its bottom can be designed with an anti-slip texture or a cushioning layer to improve the stability of the items to a certain extent. The structural features in this embodiment work together to not only improve the flexibility and ease of use of the tabletop, but also to a certain extent reduce the overall thickness, meeting the installation requirements of limited space in car seat backs, and has good engineering adaptability and application prospects.

[0050] In some implementations, such as Figure 2 , Figure 4 and Figure 5 As shown, to enhance the overall structural strength and durability of the first plate 1, the first plate 1 is composed of a first shell 13, a second shell 14, and a frame 15. The first shell 13 and the second shell 14 are connected by a snap-fit ​​mechanism. A stable fit is formed by the protrusions and slots located at the edges of the two shells, allowing them to form a closed shell structure after assembly. This improves the assembly efficiency of the overall structure and reduces manufacturing difficulty to some extent.

[0051] Furthermore, the frame 15 is disposed between the first shell 13 and the second shell 14, and is fixed inside the shell by embedding. Its outline matches the shape of the shell's inner cavity, providing internal support for the entire first plate 1. The frame 15 can be made of metal or high-strength engineering plastic, and has reinforcing ribs arranged in the direction of stress to enhance overall bending and compressive strength and prevent deformation during use. The outer shell can be injection molded from plastic, and the embedded frame 15 helps to achieve high mechanical strength while maintaining lightweight design. This structural configuration not only meets the strength requirements of the backrest tabletop under repeated flipping and impact conditions, but also makes the overall structure more stable, which helps to extend the product's service life.

[0052] Secondly, this application also provides a seat backrest, including the backrest table of the first aspect. This seat backrest possesses all the beneficial effects of the aforementioned backrest table, which will not be elaborated upon here.

[0053] In some embodiments, to securely mount the backrest table within the seat structure, the seat back also includes a backrest body 4, with the backrest table connected to the back area of ​​the backrest body 4. The backrest body 4 constitutes the load-bearing structure for the entire seat back, with its front facing the front passenger and its back facing the rear passenger. The backrest table is positioned at the back, facilitating operation by rear passengers for temporarily placing miscellaneous items, electronic devices, or other portable items.

[0054] It is understandable that, in order to achieve a secure connection between the backrest table and the backrest body 4, the seat back is also equipped with a connecting frame 5, which is used to structurally fix the first plate 1 and the backrest body 4. The first shell 13 of the first plate 1 has an opening 131, which is a through structure to form an installation channel. The frame 15 inside the first plate 1 has a connecting part 151, which is located within the opening 131 and its specific position corresponds to the opening 131. The first end of the connecting frame 5 passes through the opening 131 of the first shell 13 and is fixedly connected to the connecting part 151 of the frame 15. The connection method can be screwed, snap-fitted, or welded, etc., to form a stable structural connection.

[0055] Furthermore, the second end of the connecting frame 5 is connected to the backrest body 4. The connection position is generally selected at the frame part of the backrest body 4 to obtain stronger support. The connecting frame 5 can be made of metal or high-strength engineering plastic, and its overall length and shape are set according to the distance between the backrest table and the backrest body 4. This connection method enhances the bonding strength between the backrest table and the backrest body 4 to a certain extent, which is beneficial to coping with the vibration and impact generated during vehicle operation and improving the robustness and stability of the entire structure. At the same time, the setting of the opening 131 and the connecting part 151 facilitates the rapid positioning and operation of the connecting frame 5 during assembly, improves manufacturing efficiency, and meets the requirements for integrated installation of automotive seat backrests.

[0056] Thirdly, this application also provides a car seat that includes the aforementioned seat backrest, which has all the beneficial effects of a seat backrest, as will not be repeated here.

[0057] It is understood that the car seat is installed in a vehicle, which can be a gasoline-powered vehicle, a plug-in hybrid vehicle, or a new energy vehicle, etc., and this disclosure does not make any specific limitations.
