Description

Technical Field

[0001] This application belongs to the field of elbow pillow assembly technology, specifically relating to an elbow pillow assembly and a vehicle. Background Technology

[0002] In the field of vehicle interior design, elbow rest assemblies are usually located in the middle of the seat to provide support for the driver's and passengers' arms, relieving fatigue during long driving or riding. At the same time, the elbow rest assembly is equipped with storage space for storing items.

[0003] In related technologies, the elbow rest assembly cannot be suspended at the required angle after being opened. The elbow rest can only be kept at the required angle by opening it to the maximum angle or by the driver or passenger holding the elbow rest with their hand. Utility Model Content

[0004] The purpose of this application is to provide an elbow rest assembly and vehicle that can solve the problem in the related art that the elbow rest cannot be suspended at the required angle after being opened.

[0005] In a first aspect, embodiments of this application provide an elbow pillow assembly, the elbow pillow assembly including an elbow pillow and a frame, the elbow pillow and the frame being rotatably connected by a hinge mechanism, the hinge mechanism including: A first hinge and a second hinge, one of which is connected to the elbow rest and the other is connected to the skeleton, the first hinge and the second hinge being rotatably connected by a pivot. A damping elastic element is disposed on the first hinge and located on the rotation path of the second hinge. The damping elastic element can apply an elastic force to the second hinge to fix the first hinge and the second hinge relatively. The damping elastic element is offset from the rotating shaft.

[0006] In this embodiment, a damping elastic element is disposed on the first hinge and located on the rotation path of the second hinge. The damping elastic element can apply a spring force to the second hinge to fix the first hinge and the second hinge relatively. This arrangement allows the spring force applied by the damping elastic element to generate appropriate resistance when the first hinge and the second hinge rotate relative to each other. When the elbow rest is opened to a specific angle, this resistance can balance the elbow rest's own weight and other forces, allowing the elbow rest to remain stably at that angle, achieving precise angle positioning. For example, users can open the elbow rest to any comfortable angle according to their needs, such as 45°, 60°, etc. The elbow rest can be reliably fixed at these angles, facilitating the user's access to items.

[0007] The damping elastic element is offset from the rotating shaft, allowing it to be installed and removed independently of the shaft. This eliminates the need for complex operations on the shaft during installation and removal, effectively simplifying the process, improving production efficiency, and reducing maintenance costs. Furthermore, it minimizes the impact on the connection and relative position of the first and second hinges, reducing assembly difficulty and error rates, and ensuring the reliability of the connection between the first and second hinges, thus maintaining the overall stability of the hinge mechanism.

[0008] Optionally, the damping elastic element is detachably connected to the first hinge via a fastener. This configuration improves the stability of the damping elastic element.

[0009] Optionally, the damping elastic element is snapped into the first hinge. This design allows operators to quickly snap the damping elastic element into the corresponding position on the first hinge during production assembly or maintenance, effectively shortening installation time and thus improving production and maintenance efficiency. Furthermore, when the damping elastic element needs replacement due to wear, aging, or damage, the snap-fit ​​mechanism makes disassembly easy. Operators do not need to spend significant time and effort disassembling other related components; they can simply remove the damping elastic element from the first hinge and snap in a new one to complete the replacement, reducing maintenance costs and operational difficulty. Additionally, no tools are required for installing and removing the damping elastic element, making operation convenient.

[0010] Optionally, the first hinge includes a first side plate, the second hinge includes a second side plate, the first side plate and the second side plate are rotatably connected by the pivot, the first side plate is provided with an installation space, a portion of the damping elastic element is located in the installation space, and another portion of the damping elastic element protrudes from the installation space along the direction from the first side plate to the second side plate; The first side plate is provided with a first limiting part and a second limiting part. In the direction from the first side plate to the second side plate, the first limiting part is in limiting cooperation with the damping elastic element, and in the direction from the second side plate to the first side plate, the second limiting part is in limiting cooperation with the damping elastic element.

[0011] This design provides a clear mounting position for the damping elastic element, allowing it to be accurately fixed to the first side plate. The damping elastic element protrudes from the mounting space in the direction from the first to the second side plate, enabling it to directly contact the second side plate and generate an interaction force. This provides stable damping force when the first and second hinges rotate relative to each other. The damping elastic element is firmly constrained by the first and second limiting parts, effectively enhancing its stability within the mounting space and ensuring that the damping elastic element is not easily dislodged during use.

[0012] Optionally, the first side plate is further provided with an operating space, which is offset from the installation space and is connected to the installation space, and the damping elastic element can move between the operating space and the installation space.

[0013] This design provides the operator with a direct and clear operating position. When assembling or disassembling the damping elastic component, the operator does not need to search for the operating position within the complex structure; they can simply insert tools or fingers into the operating space to easily remove the damping elastic component from or install it into the installation space. Furthermore, the staggered arrangement of the operating space and the installation space makes full use of the space of the first side plate. This layout ensures that the installation space provides a stable installation position for the damping elastic component while reserving sufficient area for the operating space, so that the assembly and disassembly operations are not interfered with by other components.

[0014] Optionally, a third limiting part is provided in the operating space, and the third limiting part cooperates with the damping elastic element in the direction from the operating space to the installation space.

[0015] With this configuration, when the hinge mechanism is subjected to external force, especially a force that causes the damping elastic element to tend to move in the direction of the operating space, the third limiting part can effectively prevent the damping elastic element from dislodging from the installation space.

[0016] Optionally, the third limiting part is disposed on the first limiting part, and the first limiting part is an elastic structure.

[0017] This design allows operators to more easily push the damping elastic element into the installation space during installation, as the first limiting part is an elastic structure. This reduces jamming and resistance during installation, improving efficiency. When disassembling the damping elastic element, operators only need to apply a certain external force to cause elastic deformation of the first limiting part, releasing the limiting fit between the third limiting part and the damping elastic element. This allows the damping elastic element to easily detach from the installation space, effectively shortening disassembly time and reducing operational difficulty.

[0018] Optionally, the hinge mechanism further includes a damping sound-absorbing pad disposed between the damping elastic element and the second hinge. This arrangement further increases the friction between the damping elastic element and the second hinge, thereby enhancing the damping effect. Simultaneously, during the opening and closing of the elbow rest, the damping sound-absorbing pad acts as a buffer and isolation layer, reducing direct contact and collisions between components and lowering noise levels. Furthermore, the damping sound-absorbing pad can also serve as an intermediate buffer layer, reducing direct contact and friction between the two components and minimizing wear on the second hinge and the damping elastic element.

[0019] Optionally, the first hinge includes at least two first side plates, and the second hinge includes at least two second side plates, with each first side plate corresponding to each second side plate, and the first side plates and the second side plates being rotatably connected by the pivot. The hinge mechanism includes at least two damping elastic elements, each damping elastic element is disposed on each of the first side plates, and each damping elastic element can apply elastic force to the corresponding second side plate.

[0020] This design improves the stability of the connection between the first and second hinges and ensures that the second hinge is subjected to a uniform force during rotation, preventing it from wobbling or jamming due to uneven force distribution.

[0021] Secondly, embodiments of this application also provide a vehicle, the vehicle including a body and the elbow rest assembly described in any of the above claims, the elbow rest assembly being disposed within the body.

[0022] The beneficial effects achieved by the vehicle provided in this application embodiment are the same as those achieved by the elbow pillow assembly described above, and will not be repeated here. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0026] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] In related technologies, the elbow rest assembly includes an elbow rest and a frame connected to the vehicle body. The elbow rest and the frame are connected by a hinge mechanism. After the elbow rest is opened, it is held at the required angle by a damping element on the hinge mechanism. However, the damping element is sleeved on the pivot of the hinge mechanism. When the damping element is disassembled and installed, it needs to be assembled together with the pivot, which is inconvenient for disassembling and installing the damping element.

[0028] The elbow pillow assembly and vehicle provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0029] refer to Figures 1-11 The elbow pillow assembly provided in this application embodiment may include an elbow pillow 100 and a frame 200, such as... Figure 1 As shown, the elbow pillow 100 and the frame 200 can be rotatably connected by a hinge mechanism 300.

[0030] Among them, such as Figure 3 As shown, the hinge mechanism 300 may include a first hinge 310, a second hinge 320, and a damping elastic element 340.

[0031] One of the first hinge 310 and the second hinge 320 can be used to connect to the elbow rest 100, and the other can be used to connect to the frame 200. The first hinge 310 and the second hinge 320 can be rotatably connected via a pivot 330. This arrangement allows the elbow rest 100 to rotate relative to the frame 200, thereby facilitating the opening and closing of the elbow rest 100.

[0032] like Figures 3-5As shown, the damping elastic element 340 can be disposed on the first hinge 310 and located on the rotation path of the second hinge 320. The damping elastic element 340 can apply a spring force to the second hinge 320 to fix the first hinge 310 and the second hinge 320 relative to each other. With this configuration, the spring force applied by the damping elastic element 340 can generate appropriate resistance when the first hinge 310 and the second hinge 320 rotate relative to each other. When the elbow rest 100 is opened to a specific angle, this resistance can balance the weight of the elbow rest 100 itself and other forces (such as the spring force of the opening elastic element 360 described below), allowing the elbow rest 100 to remain stably at that angle, achieving precise angle positioning. For example, the user can open the elbow rest 100 to any comfortable angle according to their needs, such as 45°, 60°, etc. The elbow rest 100 can be reliably fixed at these angles, making it convenient for the user to pick up and put down items.

[0033] Among them, such as Figures 2-4 As shown, the damping elastic element 340 and the rotating shaft 330 can be offset from each other. This arrangement allows the damping elastic element 340 to be installed and removed independently of the rotating shaft 330. When installing and removing the damping elastic element 340, there is no need for complex operations on the rotating shaft 330, effectively simplifying the installation and removal of the damping elastic element 340, improving production efficiency, and reducing subsequent maintenance costs. Simultaneously, it does not easily affect the connection and relative position of the first hinge 310 and the second hinge 320, reducing assembly difficulty and error rate, and ensuring the reliability of the connection between the first hinge 310 and the second hinge 320, thereby ensuring the overall stability of the hinge mechanism 300.

[0034] In one alternative embodiment of this application, such as Figure 4 As shown, the damping elastic element 340 can be detachably connected to the first hinge 310 via the fastener 313. This configuration improves the stability of the damping elastic element 340.

[0035] In an optional embodiment, the fastener 313 may include screws or rivets, meaning that the damping elastic element 340 may be detachably connected to the first hinge 310 by screws or rivets.

[0036] In this embodiment, the damping elastic member 340 may be provided with a first mounting hole, the first hinge 310 may be provided with a second mounting hole, and the fixing member 313 may pass through the first mounting hole and connect with the second mounting hole so that the damping elastic member 340 is fixed on the first hinge 310.

[0037] Optionally, such as Figure 5As shown, the damping elastic member 340 may include a connecting portion 341 and an elastic portion 342. The elastic portion 342 may be connected to the connecting portion 341, and the connecting portion 341 may be connected to the first hinge 310 via a fixing member 313, thereby realizing the connection between the damping elastic member 340 and the first hinge 310. Furthermore, the elastic portion 342 may protrude from the connecting portion 341, so that the elastic portion 342 can apply elastic force to the second hinge 320.

[0038] Here, a first mounting hole may be provided on the connecting part 341.

[0039] To improve the stability of the damping elastic element 340, the damping elastic element 340 can be connected to the first hinge 310 by at least two fasteners 313.

[0040] In another optional embodiment of this application, the damping elastic element 340 can be snapped into the first hinge 310. This configuration allows operators to quickly snap the damping elastic element 340 into the corresponding position of the first hinge 310 during production assembly or maintenance, effectively shortening installation time and thus improving production and maintenance efficiency. Furthermore, when the damping elastic element 340 needs replacement due to wear, aging, or damage, the snap-fit ​​method makes disassembly easy. Operators do not need to spend significant time and effort disassembling other related components; they can simply remove the damping elastic element 340 from the first hinge 310 and snap in a new one to complete the replacement, reducing maintenance costs and operational difficulty. Additionally, no tools are required for installing and removing the damping elastic element 340, making the operation convenient.

[0041] In optional embodiments, such as Figure 1 and Figure 3 As shown, the first hinge 310 may include a first side plate 312, such as Figure 3 As shown, the second hinge 320 may include a second side plate 322, and the first side plate 312 and the second side plate 322 may be rotatably connected by a pivot 330, such as... Figure 6 , Figure 7 and Figure 10As shown, a mounting space 3121 can be provided on the first side plate 312. A portion of the damping elastic member 340 can be disposed within the mounting space 3121, and another portion of the damping elastic member 340 can protrude from the mounting space 3121 along the direction from the first side plate 312 to the second side plate 322. In this embodiment, the mounting space 3121 can provide a clear mounting position for the damping elastic member 340, allowing the damping elastic member 340 to be accurately fixed on the first side plate 312. The damping elastic member 340 protrudes from the mounting space 3121 along the direction from the first side plate 312 to the second side plate 322, enabling the damping elastic member 340 to directly contact the second side plate 322 and generate an interaction force, thereby providing a stable damping force when the first hinge 310 and the second hinge 320 rotate relative to each other.

[0042] In other embodiments, the first side plate 312 may not have an installation space 3121. For example, a clip may be provided on the side of the first side plate 312 facing the second side plate 322, and the clip may engage with the damping elastic member 340.

[0043] Optionally, such as Figure 6 and Figure 11 As shown, a first limiting part 3122 and a second limiting part 3123 may be provided on the first side plate 312. In the direction from the first side plate 312 to the second side plate 322, the first limiting part 3122 is limited and cooperates with the damping elastic member 340; in the direction from the second side plate 322 to the first side plate 312, the second limiting part 3123 is limited and cooperates with the damping elastic member 340. In this embodiment, in the direction from the first side plate 312 to the second side plate 322, the first limiting part 3122 limits the damping elastic member 340, which can effectively prevent the damping elastic member 340 from moving towards the second side plate 322 and detaching from the installation position; in the direction from the second side plate 322 to the first side plate 312, the second limiting part 3123 restricts the damping elastic member 340 from moving along the direction from the second side plate 322 to the first side plate 312, so that the damping elastic member 340 is firmly constrained in both directions, effectively enhancing the stability of the damping elastic member 340 in the installation space 3121, and ensuring that the damping elastic member 340 is not easily accidentally dislodged during the use of the entire hinge structure.

[0044] In other embodiments, the first limiting part 3122 may not be provided on the first side plate 312.

[0045] In this embodiment, as Figure 3As shown, the first hinge 310 may include a first hinge main board 311, which can be connected to the frame 200 by a first screw. The first side plate 312 can be connected to the first hinge main board 311. The second hinge 320 may include a second hinge main board 321, which can be connected to the elbow rest 100 by a second screw. The second side plate 322 can be connected to the second hinge main board 321.

[0046] In optional embodiments, such as Figures 6-11 As shown, an operating space 3124 is also provided on the first side plate 312. The operating space 3124 is offset from the installation space 3121, allowing the damping elastic element 340 to move between the operating space 3124 and the installation space 3121. In this embodiment, the operating space 3124 provides the operator with a direct and clear installation position. When assembling or disassembling the damping elastic element 340, the operator does not need to search for the operating position in a complex structure. They only need to insert tools or fingers into the operating space 3124 to easily remove the damping elastic element 340 from or install it into the installation space 3121. Furthermore, the offset arrangement of the operating space 3124 and the installation space 3121 makes full use of the space of the first side plate 312. This layout ensures that the installation space 3121 provides a stable installation position for the damping elastic element 340, while also reserving sufficient area for the operating space 3124, so that the assembly and disassembly operations are not interfered with by other components.

[0047] In other embodiments, the operating space 3124 may not be provided on the first side plate 312.

[0048] In one alternative embodiment, such as Figures 6-11 As shown, the operating space 3124 can extend through the first side plate 312, which facilitates processing.

[0049] In another alternative embodiment, the operating space 3124 can be a groove, with the groove opening facing away from the second side plate 322. This arrangement allows the entrance to the operating space 3124 to be located outside the first side plate 312, facilitating operation by the operator.

[0050] In optional embodiments, such as Figure 6 , Figure 8 and Figure 10As shown, a third limiting part 3125 may be provided within the operating space 3124. Along the direction from the operating space 3124 to the installation space 3121, the third limiting part engages with the damping elastic member 340. In this embodiment, the third limiting part 3125 blocks the damping elastic member 340 in the direction from the operating space 3124 to the installation space 3121. When the hinge mechanism 300 is subjected to an external force, especially a force that causes the damping elastic member 340 to tend to move towards the operating space 3124, the third limiting part 3125 can effectively prevent the damping elastic member 340 from dislodging from the installation space 3121.

[0051] In other embodiments, the second limiting part 3123 may not be provided in the operating space 3124.

[0052] In optional embodiments, such as Figure 6 , Figure 8 and Figure 10 As shown, the third limiting part 3125 can be disposed on the first limiting part 3122, and the first limiting part 3122 can be an elastic structure. With this configuration, when installing the damping elastic element 340, because the first limiting part 3122 is an elastic structure, the operator can more easily push the damping elastic element 340 into the installation space 3121. When the damping elastic element 340 contacts the third limiting part 3125, the first limiting part 3122 will undergo elastic deformation, providing a certain clearance space for the damping elastic element 340, allowing the damping elastic element 340 to smoothly enter the installation space 3121 through the opening, reducing jamming and resistance during installation and improving installation efficiency. When disassembling the damping elastic element 340, the operator only needs to apply a certain external force to cause the first limiting part 3122 to undergo elastic deformation, which can release the limiting fit between the third limiting part 3125 and the damping elastic element 340, allowing the damping elastic element 340 to easily come out of the installation space 3121. This can effectively shorten the disassembly time and reduce the difficulty of operation.

[0053] In some embodiments, such as Figure 6 and Figure 10 As shown, the third limiting part 3125 is provided with a first guide surface 31251. Along the direction from the operating space 3124 to the installation space 3121, the distance between the first guide surface 31251 and the first limiting part 3122 gradually increases. In this embodiment, when the damping elastic member 340 moves from the operating space 3124 to the installation space 3121, the first guide surface 31251 can provide a clear guiding path for the damping elastic member 340. The damping elastic member 340 can naturally slide towards the installation space 3121 along the inclined direction of the first guide surface 31251, without requiring the operator to precisely align the installation position, effectively improving the accuracy and efficiency of installation, and reducing the difficulty of installation.

[0054] Optionally, such as Figure 7 and Figure 11 As shown, a second guide surface 31231 may be provided on the side of the second limiting part 3123 near the operating space 3124. Along the direction from the operating space 3124 to the installation space 3121, the distance between the second guide surface 31231 and the first limiting part 3122 gradually decreases. With this configuration, when the damping elastic member 340 moves from the operating space 3124 to the installation space 3121, the second guide surface 31231 can provide guidance for the damping elastic member 340, allowing the damping elastic member 340 to slide naturally into the installation space 3121 along the inclined direction of the second guide surface 31231, further reducing the installation difficulty of the damping elastic member 340.

[0055] Further, optionally, to improve the installation stability of the damping elastic element 340, such as Figure 6 , Figure 8 and Figure 10 As shown, a fourth limiting part 3126 may also be provided on the first side plate 312. The fourth limiting part 3126 may be spaced apart from the second limiting part 3123, and in the direction from the second side plate 322 to the first side plate 312, the fourth limiting part 3126 engages with the damping elastic member 340 for limiting. With this arrangement, the fourth limiting part 3126 can further constrain and block the damping elastic member 340, thereby improving the installation stability of the damping elastic member 340.

[0056] In addition, such as Figure 6 , Figure 8 and Figure 10 As shown, a fifth limiting part 3127 may also be provided within the operating space 3124. The fifth limiting part 3127 may be spaced apart from the third limiting part 3125, and in the direction from the mounting space 3121 to the operating space 3124, the fifth limiting part 3127 engages with the damping elastic member 340 for limiting. With this configuration, the fifth limiting part 3127 blocks the damping elastic member 340 in the direction from the operating space 3124 to the mounting space 3121, thereby further preventing the damping elastic member 340 from dislodging from the mounting space 3121.

[0057] In some embodiments, such as Figure 8 and Figure 9 As shown, a fixing plate 3128 can also be provided on the side of the first side plate 312 away from the second side plate 322. In the direction from the second side plate 322 to the first side plate 312, the fixing plate 3128 is matched with the elastic part 342 of the damping elastic member 340. With this arrangement, the fixing plate 3128 can block the elastic part 342 of the damping elastic member 340, so as to prevent the elastic part 342 from bending away from the second side plate 322 after being subjected to force and thus failing to dampen the second side plate 322.

[0058] In optional embodiments, such as Figure 4 As shown, the hinge mechanism 300 also includes a damping sound-absorbing pad 350, which is disposed between the damping elastic element 340 and the second hinge 320. This arrangement can further increase the friction between the damping elastic element 340 and the second hinge 320, thereby further enhancing the damping effect. Simultaneously, during the opening and closing process of the elbow rest 100, the damping sound-absorbing pad 350 can act as a buffer and isolation layer, reducing direct contact and collision between components and lowering noise levels. Furthermore, the damping sound-absorbing pad 350 can also serve as an intermediate buffer layer, reducing direct contact and friction between the two components and decreasing the wear on the second hinge 320 and the damping elastic element 340.

[0059] In other embodiments, the hinge mechanism 300 may also exclude the damping sound-absorbing pad 350.

[0060] Optionally, the damping sound-absorbing pad 350 can be disposed on the side of the second side plate 322 of the second hinge 320 facing the first side plate 312, and can contact the damping elastic member 340.

[0061] In this embodiment, the damping sound-absorbing pad 350 can be made of materials such as felt or plastic.

[0062] In optional embodiments, such as Figure 3 As shown, the first hinge 310 may include at least two first side plates 312, and the second hinge 320 may include at least two second side plates 322. Each first side plate 312 may correspond one-to-one with each second side plate 322, and the first side plates 312 and the second side plates 322 may be rotatably connected by a pivot 330. This arrangement can improve the stability of the connection between the first hinge 310 and the second hinge 320.

[0063] like Figure 3 As shown, the hinge mechanism 300 may include at least two damping elastic elements 340, each of which may be respectively disposed on each of the first side plates 312, and each damping elastic element 340 may apply elastic force to the corresponding second side plate 322. This arrangement ensures that the second hinge 320 is subjected to a uniform force during rotation, preventing the second hinge 320 from wobbling or jamming due to uneven force distribution.

[0064] In this embodiment, the first hinge 310 may include two first side plates 312, which may be located on both sides of the first hinge main board 311 in the axial direction of the pivot 330. The second hinge 320 may include two second side plates 322, which may be located on both sides of the second hinge main board 321 in the axial direction of the pivot 330.

[0065] In other embodiments, the first hinge 310 may also include a first side plate 312, the second hinge 320 may also include a second side plate 322, and the hinge mechanism 300 may also include a damping elastic element 340.

[0066] In some embodiments, the damping elastic element 340 may include a connecting portion 341 and an elastic portion 342 connected to the connecting portion 341. The connecting portion 341 may be a flat plate structure and is connected to the first side plate 312. The elastic portion 342 protrudes from the connecting portion 341 so that the elastic portion 342 can act on the second side plate 322. Furthermore, the connecting portion 341 and the elastic portion 342 are sequentially distributed along the opening path of the elbow rest 100. The connecting portion 341 can only contact the elastic portion 342 after the elbow rest 100 is opened to a certain angle, thus achieving the hovering function. For example, the second hinge 320 only contacts the elastic portion 342 when the elbow rest 100 is opened to 45°. This arrangement eliminates the need to hover the elbow rest 100 throughout its entire rotation range, and avoids the need for hovering when the opening angle of the elbow rest 100 is small. Furthermore, when the elbow pillow 100 is in the closed state, the second side plate 322 does not contact the elastic part 342, thereby reducing the squeezing effect on the elastic part 342 and thus helping to improve the service life of the elastic part 342.

[0067] In optional embodiments, such as Figure 1 As shown, the hinge mechanism 300 may further include an opening elastic element 360, which can be sleeved on the pivot 330. One end of the opening elastic element 360 can be connected to the pivot 330, and the other end of the opening elastic element 360 can be connected to the second hinge main board 321. The opening elastic element 360 can provide elastic force to the second hinge main board 321 so that the elbow pillow 100 can open automatically.

[0068] Optionally, the hinge mechanism 300 may include at least two opening elastic elements 360, which may be spaced apart along the axial direction of the pivot 330. This arrangement helps to ensure the force balance of the second hinge 320.

[0069] For example, the opening elastic element 360 can be a torsion spring.

The elbow rest assembly may be disposed inside the vehicle body, and the frame 200 of the elbow rest assembly may be connected to the vehicle frame.
