Description

Technical Field

[0001] This application belongs to the field of automotive elbow pad adjustment technology, and particularly relates to an elbow pillow structure and vehicle. Background Technology

[0002] In modern automotive interior design, the passenger-side dashboard elbow rest is an important component that enhances driving comfort and storage functionality, and is widely used in various vehicle models.

[0003] In the prior art, the vehicle sub-instrument is longitudinally installed in the center of the vehicle's cockpit, extending from the front center console to the rear of the vehicle. The interior of the vehicle sub-instrument is hollow and has an opening at the top. An open-structure sub-instrument elbow rest is located at the top of the vehicle sub-instrument and covers its top opening, used to open or close the storage space set inside the vehicle sub-instrument.

[0004] However, the opening speed of the aforementioned split-opening sub-dashboard elbow rest is uncontrollable, and it is easy to open too fast or too slow. Opening too fast may cause safety hazards due to passenger misoperation, while opening too slow will affect efficiency, reduce practicality, and result in a poor overall user experience. Utility Model Content

[0005] This application addresses, to at least some extent, one of the technical problems in the related art.

[0006] Therefore, this application aims to provide an elbow rest structure and vehicle, which solves the problem of uncontrollable opening speed of the elbow rest in the prior art by quickly changing the output elastic force of the elastic element through a novel structural design of the elbow rest structure.

[0007] To achieve the above objectives, this application provides an elbow pillow structure, comprising: Elbow pillow base; The connector has one end mounted on the vehicle's sub-dashboard and the other end rotatably mounted on the elbow rest base, for the purpose of allowing the elbow rest base to rotate around the vehicle's sub-dashboard. An adjusting component is provided on the elbow pillow base, and the adjusting component is provided with multiple limiting grooves of different depths; An elastic element, one end of which is connected to the connector, and the other end of which extends into any of the limiting grooves, outputs different elastic forces based on the depth of each limiting groove to adjust the relative rotation speed between the elbow rest base and the vehicle sub-instrument panel.

[0008] In the existing technology, the opening speed of the split-type sub-dashboard elbow rest is uncontrollable, and it is easy to open too fast or too slow. Opening too fast may cause safety hazards due to passenger misoperation, while opening too slow will affect efficiency, reduce practicality, and result in a poor overall user experience.

[0009] Based on the above technical solution, this application sets multiple different limiting grooves on the adjusting component to cooperate with the compression elastic component, so that the elastic component outputs different elastic forces to drive the elbow pillow base, thereby achieving precise control of the rotation speed of the elbow pillow base and solving the problem of uncontrollable elbow pillow opening speed in the prior art.

[0010] In some embodiments, a plurality of the limiting grooves are arranged adjacent to each other on the adjusting member around a central point.

[0011] Based on the above technical solution, by arranging multiple limiting grooves in a ring, the transition between adjacent limiting grooves can be made smoother, which helps to improve the introduction efficiency and adjustment continuity of the elastic component. This makes the adjustment process of the elastic component more suitable for application scenarios that require high-frequency adjustment or long-term use, effectively extending the service life of the adjustment component and the elastic component, and reducing maintenance costs.

[0012] In some embodiments, the plurality of limiting grooves are arranged from shallow to deep based on their respective depths, with the deepest limiting groove adjacent to the shallowest limiting groove, and a first positioning mark provided between them.

[0013] Based on the above technical solution, the arrangement of the limit groove depth from shallow to deep provides an orderly elastic force level switching path, making the feedback during the elbow pillow adjustment process more predictable and controllable; the setting of the first positioning mark further enhances the visual recognition capability of the adjustment structure, which helps to quickly determine the resistance range of the current adjustment position during the adjustment process, and improves the user's or assembler's operational intuition and sense of control.

[0014] In some embodiments, the adjusting member is detachably disposed on the elbow rest base, and the elbow rest base is further provided with a second positioning mark, the second positioning mark being used to cooperate with the first positioning mark to indicate the position of the limiting groove into which the elastic member currently extends on the adjusting member.

[0015] Based on the above technical solution, the maintainability and modularity of the overall structure are improved by setting detachable adjustment parts, which facilitates later maintenance or replacement of adjustment parts and reduces usage costs. By setting paired first and second positioning marks on the elbow rest base and adjustment parts, the position of the limit groove can be intuitively indicated, improving the user's adjustment experience and helping to accurately calibrate the adjustment components during assembly, ensuring the normal operation of the elbow rest adjustment function.

[0016] In some embodiments, the elbow pillow structure further includes: The adjusting member is rotatably mounted on the elbow pillow base, and the center point is located on the rotating shaft of the adjusting member; A locking structure is provided between the adjusting member and the elbow pillow base to lock the relative rotation of the adjusting member and the elbow pillow base.

[0017] Based on the above technical solution, by setting the adjusting component to be rotatably mounted on the elbow rest base, the directional adjustment capability of the adjusting component is enhanced. Users can customize the position of the limit groove according to their personal habits, further improving the ergonomic adaptability. The locking structure ensures that the adjusting component remains stable after adjustment, enhances the reliability of the output resistance of the adjusting component and the elastic component, and prevents the adjusting component from malfunctioning or loosening during use.

[0018] In some embodiments, the locking structure includes: At least one of the locking slots is provided on the adjusting member at one end away from the limiting slot; A locking component, fixed to the elbow rest base, is used to extend into the locking groove to lock the relative rotation of the adjusting component and the elbow rest base.

[0019] Based on the above technical solution, by setting the locking groove and the locking component in a cooperative structure, the unexpected rotation of the adjusting component due to vibration or misoperation can be effectively avoided, thus improving the structural stability and safety. The cooperation between the locking groove and the locking component also prevents the adjusting component from disengaging and rotating under the reaction force of the elastic component, improving the reliability of the connection between the adjusting component and the elbow rest base, ensuring that the cooperative position of the limiting groove and the elastic component remains stable, and avoiding the failure of the output resistance of the elastic component due to the rotation of the adjusting component.

[0020] In some embodiments, the elbow pillow structure further includes: A mounting groove is provided on the elbow pillow base, and a locking member is provided in the mounting groove. The mounting groove is used to lock the adjusting member relative to the elbow pillow base in a direction perpendicular to its rotation axis.

[0021] Based on the above technical solution, by setting an installation groove to accommodate the adjusting component, the movement of the adjusting component relative to the elbow rest base in the direction perpendicular to its rotation axis is restricted. This allows the elbow rest base to directly restrict the adjusting component as a whole, avoiding local friction between the adjusting component and the adjusting component's rotation axis to prevent excessive wear and improving the service life of the adjusting component's rotation axis.

[0022] In some embodiments, the elastic element includes: The elastic part is used to output elastic force; A connecting portion is provided at one end of the elastic portion to connect the connecting member; An abutment portion is provided at the end of the elastic portion away from the connecting portion, and the abutment portion is used to extend into any of the limiting grooves and abut against the bottom of the groove.

[0023] Based on the above technical solution, the variable control of rotational resistance between the adjusting component and the rotating component is achieved through the cooperation of the connecting part, the elastic part, and the abutting part. Among them, the elastic part is responsible for locking the mechanical response of the structure, the connecting part ensures stable assembly, and the abutting part achieves precise contact and guidance. The overall structure optimizes the adjustment performance and improves the smoothness and response accuracy of the elbow pillow base rotation control.

[0024] In some embodiments, the elastic element further includes: A limiting part is provided at the end of the abutting part away from the elastic part, and the limiting part is used to prevent the abutting part from sliding out after extending into the limiting groove.

[0025] Based on the above technical solution, by setting a limiting part, the positioning effect of the elastic element in the limiting groove can be significantly enhanced, effectively avoiding the problem of the abutting part disengaging from the limiting groove due to uneven force or external disturbance during dynamic operation, thus improving the safety and durability of the overall structure; at the same time, the user or assembly personnel can easily move the abutting part away from or closer to the adjusting part through the limiting part, thereby facilitating the adjustment of the fit between the elastic element and the adjusting part, and thus adjusting the rotation resistance of the elbow pad.

[0026] On the other hand, this application also provides a vehicle in which the elbow pad is provided with the elbow rest structure described in any of the above claims. Based on the above technical solution, the elbow rest structure is set in the elbow pad of the vehicle to achieve precise control of the elbow rest rotation speed, improve the vehicle riding experience and the personalized adjustment capability of the vehicle's elbow rest.

[0031] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0032] In modern automotive interior design, the vehicle's secondary dashboard is mounted longitudinally in the center of the vehicle's cockpit, extending from the front center console towards the rear of the vehicle, passing between the two front seats, and extending to the front of the rear seats; the secondary dashboard separates the driver's seat and the passenger seat, and is the framework of the vehicle's interior space layout.

[0033] The vehicle's sub-dashboard is hollow inside and open at the top. The sub-dashboard elbow rest is located at the top of the vehicle's sub-dashboard and covers its top opening. It is used to open or close the storage space inside the vehicle's sub-dashboard. Therefore, the vehicle's sub-dashboard elbow rest is an important component for improving driving comfort and storage function, and is widely used in various types of vehicles.

[0034] In the prior art, a common type of secondary instrument panel elbow rest is a split-type structure, which includes an elbow rest base, a mechanical shaft, a secondary instrument panel, and a torsion spring. The mechanical shaft is mounted on the elbow rest base, and the secondary instrument panel is rotatably connected to the mechanical shaft. The torsion spring is sleeved on the outside of the mechanical shaft, and its two ends are connected to the elbow rest base and the secondary instrument panel, respectively, to provide elastic force to drive the elbow rest base to rotate relative to the mechanical shaft, thereby opening the elbow rest base relative to the secondary instrument panel.

[0035] However, the opening speed of the aforementioned split-opening sub-dashboard elbow rest is uncontrollable, and it is easy to open too fast or too slow. Opening too fast may cause safety hazards due to passenger misoperation, while opening too slow will affect efficiency, reduce practicality, and result in a poor overall user experience.

[0036] To address the technical problems existing in the prior art, this application provides an elbow pillow structure. By modifying the connection relationship between the elastic element 400 and the elbow pillow base 100 through a novel structural design, the output elastic force of the elastic element 400 can be quickly changed through the adjusting element 300, thereby solving the problem of uncontrollable opening speed of the elbow pillow in the prior art.

[0037] In the following text, reference will be made to the appendix. Figures 1 to 7 The implementation methods of this application are described in detail.

[0038] See attached document Figure 1 and Figure 2 In one illustrative embodiment of the elbow pillow structure of this application, the elbow pillow structure includes an elbow pillow base 100.

[0039] Specifically, the elbow rest base 100 is the mounting base for the entire elbow rest structure. The elbow rest is mounted on the elbow rest base 100, which is directly fixed to the top of the vehicle's sub-instrument panel. The elbow rest base 100 is also provided with a maintenance port and a maintenance cover, which are detachably connected to facilitate adjustment of the elastic element 400 on the elbow rest base 100 after disassembly. The elbow rest base 100 can rotate relative to the vehicle's sub-instrument panel to open or close its top opening, thereby allowing the interior of the vehicle's sub-instrument panel to communicate with or isolate itself from the outside world.

[0040] Reference Appendix Figures 1 to 7 In some embodiments, the elbow rest structure further includes a connector 200, one end of which is disposed on the vehicle's sub-dashboard and the other end is rotatably disposed on the elbow rest base 100, for the purpose of allowing the elbow rest base 100 to rotate around the vehicle's sub-dashboard.

[0041] Specifically, the connector 200 is the core motion hub and force transmission medium of the elbow rest structure. The elbow rest base 100 is provided with a fixed rotating shaft 900. One end of the connector 200 is located on the vehicle's sub-instrument panel, and the other end of the connector 200 is sleeved on the fixed rotating shaft 900, forming a stable rotating pair. This allows the vehicle's sub-instrument panel to rotate relative to the elbow rest around the fixed rotating shaft 900 via the connector 200, thereby enabling the elbow rest base 100 to rotate around the vehicle's sub-instrument panel. When the user drives the elbow rest base 100 to rotate relative to the vehicle's sub-instrument panel, the force on the elbow rest base 100 is directly transmitted to the connector 200, causing the connector 200 to rotate precisely around the fixed rotating shaft 900 on the elbow rest base 100.

[0042] Meanwhile, the elastic element 400 is sleeved outside the fixed rotating shaft 900 and one end is connected to the connecting element 200. The elastic element 400 is compressed and deformed as the connecting element 200 rotates, that is, the connecting element 200 also undertakes the function of driving the elastic element 400, thereby providing rotational resistance for the connecting element 200 to rotate around the fixed rotating shaft 900. When the other end of the elastic element 400 is selectively placed in the limiting groove 500 of different depths on the adjusting element 300, the rotation of the connecting element 200 will be subjected to a variable damping torque corresponding to the depth of the limiting groove 500.

[0043] By setting the connector 200, the rotation of the elbow rest and the deformation of the elastic element 400 are tightly coupled, ensuring direct and delay-free damping force feedback and providing users with a precise and linear feel. The rotational connection between the connector 200 and the fixed shaft 900 enables stable transmission between the vehicle's sub-dashboard and the elbow rest base 100, ensuring the structural stability of the elbow rest under long-term and frequent use, reducing wear on the fixed shaft 900, and avoiding shaking and abnormal noise.

[0044] The connector 200 includes, but is not limited to, large-bend hinges, medium-bend hinges, and straight-bend hinges; the connector 200 can be made of high-strength steel or aluminum alloy through stamping or casting processes, or by injection molding of high-performance engineering plastics.

[0045] In other embodiments, the fixed pivot 900 is replaced with a sliding bearing or a rolling bearing to reduce friction and wear, thereby improving the service life of the elbow rest structure.

[0046] Reference Appendix Figures 2 to 5 In some embodiments, the elbow pillow structure further includes an adjustment member 300, which is disposed on the elbow pillow base 100 and has multiple limiting grooves 500 of different depths.

[0047] Specifically, the adjusting component 300 is the core component for realizing the stepless adjustment function. The adjusting component 300 is located on the elbow pillow base 100 and has a series of multiple limiting grooves 500 of different depths.

[0048] Based on the different depths of the limiting grooves 500 to serve as physical levels of the preset damping force; when the end of the elastic element 400 away from the connector 200 selectively extends into different limiting grooves 500, the bottom position of the limiting groove 500 is equivalent to a stop, used to abut and determine the stationary position of the end of the elastic element 400 away from the connector 200. Therefore, the depth of the groove bottom directly determines the effective working length and initial deformation of the elastic element 400.

[0049] It should be noted that the effective working length refers to the lever arm of the elastic element 400. When the bottom position of the limiting groove 500 into which the end of the elastic element 400 away from the connector 200 extends changes from a deep position to a shallower position, it is equivalent to applying a larger initial displacement to the end of the elastic element 400 away from the connector 200. This initial displacement forces the elastic element 400 to be compressed or twisted by a corresponding deformation before the elbow base 100 begins to move, which is the initial deformation of the elastic element 400.

[0050] The initial deformation is precisely converted into the magnitude of the elastic force of the elastic element 400. The deeper the limiting groove 500, the smaller the initial deformation of the elastic element 400, thus making the elastic force output by the elastic element 400 smaller; the shallower the limiting groove 500, the larger the initial deformation of the elastic element 400, thus making the elastic force output by the elastic element 400 larger.

[0051] The elastic element 400 is connected to the connector 200 so that the elastic force output by the elastic element 400 acts on the rotation of the vehicle's sub-instrument panel relative to the elbow rest base 100. The adjusting element 300, through a series of limiting grooves 500 of different depths, transforms the damping force requirement for the rotation of the vehicle's sub-instrument panel relative to the elbow rest base 100 into a selectable mechanical structure, thereby enabling systematic control of the opening and closing speed of the elbow rest.

[0052] It should be noted that each limit groove 500 corresponds to a physical level of preset damping force. The more limit grooves 500 there are, the more physical levels of preset damping force can be selected. By setting multiple limit grooves 500 to cooperate with the elastic element 400 to adjust the output resistance, the stepless adjustment of the damping force of the vehicle's sub-instrument panel relative to the elbow base 100 can be achieved.

[0053] By setting the adjustment component 300 to cooperate with the elastic component 400, the fixed rotational damping of the elbow rest is transformed into a customizable variable, providing precise and personalized elbow rest adjustment capabilities. Through the carefully designed depth sequence of the limit groove 500, linear or non-linear damping changes from light to stable can be achieved, satisfying different users' delicate preferences for operating feel and greatly improving the product's adaptability and user experience.

[0054] Adjustment component 300 includes, but is not limited to, a dial, turntable, or slider that is independent of the elbow rest base 100, or an adjustment structure integrated into the elbow rest base 100; adjustment component 300 is a modular component that can be easily disassembled, allowing users to replace adjustment component 300 with another series of depth limiting grooves 500 to completely change the dynamic characteristics of the elbow rest; since there is repeated friction between the adjustment component 300 and the end of the elastic component 400, the material of adjustment component 300 is selected from highly wear-resistant materials, including but not limited to polyoxymethylene, nylon, or powder metallurgy steel, to ensure accuracy and feel during long-term use; the contour of the limiting groove 500 includes, but is not limited to, being U-shaped, V-shaped, or being a gradient groove with a guiding slope, so that the end of the elastic component 400 can switch more smoothly between multiple limiting grooves 500.

[0055] Reference Appendix Figure 5 In some embodiments, multiple limiting grooves 500 are arranged adjacent to each other around a central point on the adjusting member 300.

[0056] Specifically, the multiple limiting grooves 500 on the adjusting component 300 are arranged in a ring array, so that they are evenly distributed around a central point; every two adjacent limiting grooves 500 are arranged at equal or increasing angle intervals on the rotating surface of the adjusting component 300, forming a fan-shaped distribution structure, which not only improves the space utilization between the limiting grooves 500, but also facilitates the smooth switching of the elastic component 400 to different limiting grooves 500 during the rotation of the elbow rest, thereby realizing continuous resistance adjustment.

[0057] By arranging multiple limiting grooves 500 in a ring, the transition between adjacent limiting grooves 500 can be smoother, which helps to improve the introduction efficiency and adjustment continuity of the elastic element 400. This makes the adjustment process of the elastic element 400 more suitable for application scenarios that require high-frequency adjustment or long-term use, effectively extending the service life of the adjusting element 300 and the elastic element 400, and reducing maintenance costs.

[0058] It should be noted that the arrangement of the limiting grooves 500 can be either a complete circular distribution around the center point, or a partial fan-shaped arrangement, to accommodate different elbow adjustment angle requirements; the angular intervals between each limiting groove 500 can be designed to be equidistant or variable according to the requirements of resistance changes. The center point is set on the central axis of the adjusting component 300, or offset to one side according to the installation position of the elastic component 400, so as to accommodate the internal structure of different sub-instrument panels.

[0059] In other embodiments, the multiple limiting grooves 500 are arranged in a multi-concentric circle arrangement to provide more fine adjustment levels. The multi-concentric circle includes at least one inner circle and an outer circle. The inner diameter of the inner circle is smaller than the inner diameter of the outer circle. The depth of the multiple limiting grooves 500 that make up the inner circle is smaller than the depth of the multiple limiting grooves 500 that make up the outer circle, so that they do not affect each other when the inner circle or the outer circle is used in conjunction with the elastic element 400.

[0060] Reference Appendix Figure 5 In some embodiments, the plurality of limiting grooves 500 are arranged from shallow to deep based on their respective depths, with the deepest limiting groove 500 adjacent to the shallowest limiting groove 500, and a first positioning mark 600 is provided between them.

[0061] Specifically, multiple limiting grooves 500 are arranged in pairs around a central point on the adjusting member 300. The limiting grooves 500 on the adjusting member 300 are arranged in a ring according to their depth from shallow to deep. Through structural design, the deepest and shallowest limiting grooves 500 are adjacent to each other to achieve cyclic switching of depth levels. This allows the resistance of the elbow pillow adjustment to form a continuous change in strength within a complete rotation cycle.

[0062] A first positioning mark 600 is provided between the deepest and shallowest grooves of the limiting groove 500 to help users or assemblers quickly identify the positional relationship between the adjusting component 300 and the upper limiting groove 500. The first positioning mark 600 includes, but is not limited to, recessed structures, raised structures, laser etching, color markings or other symbol markings, used to indicate the elastic force level boundary corresponding to the current groove position of the limiting groove 500.

[0063] The arrangement of limit grooves with a depth of 500mm from shallow to deep provides an orderly path for switching elastic force levels, making the feedback during elbow adjustment more predictable and controllable. The adjacent arrangement of the deepest and shallowest grooves facilitates quick switching to the extreme resistance state, improving operational efficiency. The setting of the first positioning mark 600 further enhances the visual recognition capability of the adjustment structure, helping to quickly determine the resistance range of the current adjustment position during the adjustment process, improving the user's or assembler's operational intuition and sense of control.

[0064] In other embodiments, a plurality of first positioning marks 600 are disposed between pairs of adjacent limiting grooves 500 to form a complete adjustment level indication system. The first positioning marks 600 include, but are not limited to, numbers or letters.

[0065] In some embodiments, the adjusting member 300 is detachably disposed on the elbow rest base 100, and the elbow rest base 100 is also provided with a second positioning mark (not shown in the figure). The second positioning mark is used to cooperate with the first positioning mark 600 to indicate the position of the limiting groove 500 into which the elastic member 400 currently extends on the adjusting member 300.

[0066] Specifically, the adjusting component 300 is detachably mounted on the elbow rest base 100, meaning that the adjusting component 300 can move relative to the elbow rest base 100, facilitating assembly, maintenance, or replacement; the detachable connection between the adjusting component 300 and the elbow rest base 100 includes, but is not limited to, threaded engagement, quick-release slots, and magnetic installation.

[0067] Secondary positioning marks include, but are not limited to, recessed structures, raised structures, laser etching, color markings, or other symbolic engravings.

[0068] Based on the arrangement of the limiting grooves 500 of the adjusting member 300, a first positioning mark 600 is set in the corresponding position on the elbow rest base 100. By adjusting the adjusting member 300, the first positioning mark 600 on the adjusting member 300 can be matched or staggered with the second positioning mark on the elbow rest base 100. When the user adjusts the elbow rest angle to allow the elastic member 400 to enter different limiting grooves 500, by observing the relative positional relationship between the first positioning mark 600 and the second positioning mark, the depth of the limiting groove 500 where the elastic member 400 is currently located can be accurately determined, thereby clarifying the current resistance level of the elbow rest.

[0069] The detachable adjustment component 300 improves the maintainability and modularity of the overall structure, making it easier to inspect or replace the adjustment component 300 later and reducing the cost of use. By setting paired first positioning marks 600 and second positioning marks on the elbow rest base 100 and the adjustment component 300, the position of the limit groove 500 can be intuitively indicated, improving the user's adjustment experience and helping to accurately calibrate the adjustment components during assembly, ensuring the normal operation of the elbow rest adjustment function.

[0070] Reference Appendix Figures 1 to 5 In some embodiments, the adjusting member 300 is rotatably mounted on the elbow pillow base 100, with its center point located on the rotating shaft of the adjusting member 300; the elbow pillow structure also includes a locking structure disposed between the adjusting member 300 and the elbow pillow base 100, for locking the relative rotation of the adjusting member 300 and the elbow pillow base 100.

[0071] Specifically, the pivot of the adjusting component 300 is fixedly mounted on the elbow rest base 100. The adjusting component 300 is rotatably mounted on the elbow rest base 100 based on the pivot, and the pivot of the adjusting component 300 passes through the center point around which multiple limiting grooves 500 surround. When the adjusting component 300 rotates relative to the elbow rest base 100, the multiple limiting grooves 500 simultaneously rotate around the center point. The adjusting component 300 and the multiple limiting grooves 500 form a rotatable adjusting module, facilitating resistance adjustment in conjunction with the elastic component 400. Through this rotatable adjusting module, compared to the elastic component 400 being fixed in position relative to the elbow rest base 100 on the fixed pivot 900, the user can adjust the rotation angle of the limiting grooves 500 relative to the elbow rest base 100 by controlling the rotation of the adjusting component 300 relative to the elbow rest base 100, thus facilitating elbow rest resistance adjustment.

[0072] Locking structures include, but are not limited to, mechanical latches, rotary latches, spring pin locking devices, magnetic locking, or electronic locking methods.

[0073] A locking structure is added between the adjusting member 300 and the elbow rest base 100 to prevent the adjusting member 300 from being accidentally displaced during operation. This structure locks the relative rotation of the adjusting member 300 and the elbow rest base 100 after adjustment, keeping them relatively stationary. This ensures that the mating position of the limiting groove 500 and the elastic member 400 remains stable and prevents the output resistance of the elastic member 400 from failing due to the rotation of the adjusting member 300.

[0074] By rotatably mounting the adjusting component 300 onto the elbow rest base 100, the directional adjustment capability of the adjusting component 300 is enhanced. Users can customize the position of the limiting groove 500 according to their personal habits, further improving ergonomic adaptability. The locking structure ensures that the adjusting component 300 remains stable after adjustment, enhancing the reliability of the output resistance of the adjusting component 300 and the elastic component 400, and preventing malfunction or loosening of the adjusting component 300 during use.

[0075] Reference Appendix Figures 2 to 5 In some embodiments, the locking structure includes a locking groove 700 and a locking member (not shown in the figure). At least one locking groove 700 is provided on the adjusting member 300 at one end away from the limiting groove 500. The locking member is fixed on the elbow pillow base 100 and is used to extend into the locking groove 700 to lock the relative rotation of the adjusting member 300 and the elbow pillow base 100.

[0076] Specifically, one end of the adjusting member 300 is provided with at least one locking groove 700, which is disposed opposite to the limiting groove 500 at both ends of the adjusting member 300. The elbow rest base 100 is provided with a locking member corresponding to the locking groove 700. The locking member is fixed to the elbow rest base 100 and extends into the locking groove 700 in the form of plugging or elastic embedding, etc., to lock the relative rotation of the adjusting member 300 and the elbow rest base 100. After the adjusting member 300 has completed the angle adjustment, the locking member is inserted into the designated locking groove 700 to achieve mechanical locking between the adjusting member 300 and the elbow rest base 100, thereby restricting the rotation of the adjusting member 300 relative to the elbow rest base 100.

[0077] By setting the locking groove 700 and the locking component in a matching structure, the unexpected rotation of the adjusting component 300 due to vibration or misoperation can be effectively prevented, thus improving structural stability and safety. The matching of the locking groove 700 and the locking component also prevents the adjusting component 300 from disengaging and rotating under the reaction force of the elastic component 400, improving the connection reliability between the adjusting component 300 and the elbow rest base 100, ensuring that the matching position of the limiting groove 500 and the elastic component 400 remains stable, and preventing the output resistance of the elastic component 400 from failing due to the rotation of the adjusting component 300.

[0078] The locking components include, but are not limited to, elastic steel sheets, limit pins, and push-button locks, and can be configured as telescopic structures to adapt to dynamic locking requirements.

[0079] It should be noted that the number of locking slots 700 should be flexibly increased or decreased according to the accuracy requirements of the adjustment angle. The spacing can be evenly or non-evenly distributed. The more locking slots 700 there are, the more stable the connection between the adjusting part 300 and the elbow rest base 100 will be.

[0080] In some embodiments, the number of locking slots 700 is set to four, and four locking members extend into the four locking slots 700 respectively, thereby locking the relative rotation between the adjusting member 300 and the elbow pillow base 100.

[0081] Reference Appendix Figure 2 In some embodiments, the elbow pillow structure further includes a mounting groove 800, which is disposed on the elbow pillow base 100. A locking member is disposed in the mounting groove 800. The mounting groove 800 is used to lock the adjusting member 300 relative to the elbow pillow base 100 in a direction perpendicular to its rotation axis.

[0082] Specifically, the shape of the mounting groove 800 includes, but is not limited to, rectangular, arc-shaped, circular, or conical groove structures; the elbow rest base 100 is provided with the mounting groove 800 to accommodate the adjusting member 300, and a locking member is provided in the mounting groove 800. The mounting groove 800 is used to lock the movement of the adjusting member 300 in the direction perpendicular to its rotation axis. After the adjusting member 300 has completed the angle adjustment around the rotation axis and locked in rotation by the locking structure, if an external force is applied, the adjusting member 300 may be displaced in the direction perpendicular to its rotation axis, thereby causing fatigue wear of the rotating shaft of the adjusting member 300 and greatly reducing the service life of the rotating shaft of the adjusting member 300.

[0083] By providing an installation slot 800 to accommodate the adjusting member 300, the movement of the adjusting member 300 relative to the elbow rest base 100 in the direction perpendicular to its rotation axis is restricted. This allows the elbow rest base 100 to directly restrict the adjusting member 300 as a whole, avoiding local friction between the adjusting member 300 and the adjusting member 300's rotation axis to prevent excessive wear and improving the service life of the adjusting member 300's rotation axis.

[0084] Reference Appendix Figures 1 to 6 In some embodiments, the elbow rest structure further includes an elastic element 400, one end of which is connected to the connector 200, and the other end extends into any limiting groove 500. The elastic element 400 outputs different elastic forces based on the depth of each limiting groove 500 to adjust the relative rotation speed between the vehicle sub-instrument panel and the elbow rest base 100.

[0085] Specifically, the elastic element 400 is the energy conversion and execution hub of the elbow pillow structure. One end of the elastic element 400 is linked with the connector 200, and the selective position of the other end is determined by the depth of the limiting groove 500 on the adjusting element 300.

[0086] Elastic components 400 include, but are not limited to, torsion springs, helical compression springs, leaf springs, and elastic rubber bodies.

[0087] As the depth of the limiting groove 500 decreases, the free end of the spring is forced to a larger initial deflection angle, thereby generating a larger initial preload torque. When the vehicle's sub-dashboard moves relative to the elbow rest base 100, the rotation of the connecting member 200 further drives the elastic member 400, causing its total deformation to increase further from the initial deformation. The elastic member 400 resists the force that increases its total deformation, which manifests as a damping force that opposes the movement of the elbow rest base 100. Therefore, the elastic member 400 essentially acts as a variable force source, dynamically converting into a damping torque opposite to the direction of movement of the elbow rest base 100 in real time, based on the selected depth of the limiting groove 500, thus achieving precise control of the elbow rest's movement speed.

[0088] By setting the elastic element 400, a continuous, smooth and variable damping force output is provided to the rotation process of the vehicle's sub-instrument panel relative to the elbow rest base 100, ensuring that the elbow rest has good linearity and smoothness in any adjustment position. By replacing the elastic element 400 with different stiffness coefficients, or adjusting the installation relationship between the elastic element 400 and the adjusting element 300, the damping force range of the entire elbow rest base 100 can be easily calibrated.

[0089] Reference Appendix Figure 2 and Figure 6 In some embodiments, the elastic member 400 includes an elastic part 402, a connecting part 401, and an abutting part 403. The elastic part 402 is used to output elastic force; the connecting part 401 is disposed at one end of the elastic part 402 to connect the connector 200; the abutting part 403 is disposed at the end of the elastic part 402 away from the connecting part 401, and the abutting part 403 is used to extend into any limiting groove 500 and abut against the bottom of the groove.

[0090] Specifically, the connecting part 401 is located at one end of the elastic member 400 and is used to reliably connect the elastic member 400 to the connecting member 200 so that it moves synchronously with the connecting member 200; the elastic part 402 is the middle main body part, which is usually made of spring steel, rubber elastic strip or spring mechanism, and has compressible deformation capability to provide the elastic force output required for adjustment; the abutting part 403 is located at the end of the elastic member 400 away from the connecting part 401, and includes but is not limited to the form of bend, protrusion, column end or ball head, which can accurately extend into any limiting groove 500 of the adjusting member 300 and form effective contact with the bottom of the groove, so that during the rotation of the elbow pillow base 100 driven by the connecting member 200, different degrees of elastic force feedback are generated by the compression of the elastic part 402 to realize variable control of rotation resistance.

[0091] Through the cooperation of the connecting part 401, the elastic part 402, and the abutting part 403, variable control of the rotational resistance between the adjusting member 300 and the rotating member is achieved. Among them, the elastic part 402 is responsible for locking the mechanical response of the structure, the connecting part 401 ensures stable assembly, and the abutting part 403 achieves precise contact and guidance. The overall structure optimizes the adjustment performance and improves the smoothness and response accuracy of the rotation control of the elbow rest base 100.

[0092] Reference Appendix Figure 2 , Figure 4 , Figure 6 In some embodiments, the elastic member 400 further includes a limiting part 404, which is disposed at the end of the abutment part 403 away from the elastic part 402. The limiting part 404 is used to prevent the abutment part 403 from sliding out after extending into the limiting groove 500.

[0093] Specifically, a limiting part 404 is added to the end of the contact part 403 away from the elastic part 402. The limiting part 404 includes, but is not limited to, a folded, cap-shaped, flange or retaining ring structure. The diameter or size of the limiting part 404 is larger than the opening of the limiting groove 500.

[0094] When the abutment portion 403 of the elastic element 400 is inserted into the limiting groove 500 of the adjusting element 300 and contacts the bottom of the groove, the abutment portion 403 prevents the elastic element 400 from accidentally slipping out or shifting from the limiting groove 500 due to vibration, inertia or reverse force during operation through physical locking, thus ensuring a stable contact state between the elastic element 400 and the limiting groove 500, thereby maintaining the continuity and reliability of the adjusting force output.

[0095] By setting the limiting part 404, the positioning effect of the elastic element 400 in the limiting groove 500 can be significantly enhanced, effectively avoiding the problem of disengagement from the limiting groove 500 due to uneven force or external disturbance during dynamic operation, thus improving the safety and durability of the overall structure and making it suitable for use in environments where vehicles are prone to vibration and impact interference during driving. At the same time, the user or assembly personnel can easily move the abutment part 403 away from or closer to the adjusting element 300 through the limiting part 404, thereby facilitating the adjustment of the fit between the elastic element 400 and the adjusting element 300, and thus adjusting the rotation resistance of the elbow pad.

[0096] In addition, this application also provides a vehicle in which the elbow pad is provided with the elbow pillow structure in any of the above embodiments, so as to achieve precise control of the rotation speed of the elbow pillow, improve the vehicle riding experience and the personalized adjustment capability of the elbow pad in the vehicle.

[0097] When the elbow rest structure of this application is used to adjust the rotational resistance of the elbow pad, the user or assembler can remove the maintenance cover through the maintenance port provided on the elbow rest base 100 to expose the adjusting member 300 provided on the elbow rest base 100. The adjusting member 300 is rotatably mounted on the elbow rest base 100. The adjusting member 300 has a plurality of limiting grooves 500 arranged in a ring array around the center point, with the deepest and shallowest limiting grooves 500 adjacent to each other. A first positioning mark 600 is provided at the position of the deepest and shallowest limiting grooves 500, which cooperates with the second positioning mark on the elbow rest base 100 for position indication.

[0098] During adjustment, by pulling up the limiting part 404, the abutment part 403 is separated from the current limiting groove 500, and the adjusting member 300 is removed from the mounting groove 800 on the elbow pad base. After the locking groove 700 on the adjusting member 300 separates from the locking member in the mounting groove 800, torque is applied to rotate the adjusting member 300 around its axis relative to the elbow pad base 100. The adjusting member 300 is rotated until the target limiting groove 500 aligns with the abutment part 403 of the elastic member 400, and then the limiting part 404 is released to allow the abutment part 403 to fall into the target limiting groove 500.

[0099] When the abutment part 403 slides into the target limiting groove 500, the depth of the groove bottom determines the initial deformation of the elastic element 400: choosing a shallower limiting groove 500 will force the abutment part 403 to produce a larger initial displacement, thereby causing the elastic part 402 to obtain a larger initial preload torque; conversely, choosing a deeper limiting groove 500 will reduce the initial preload torque.

[0100] After selecting the limiting groove 500, release the adjusting member 300. The locking mechanism's locking member then engages in the corresponding locking groove 700, locking the relative rotation between the adjusting member 300 and the elbow rest base 100. Simultaneously, the structure of the mounting groove 800 effectively restricts the movement of the adjusting member 300 in the direction perpendicular to its rotation axis. Finally, reinstall the maintenance cover.

[0101] At this time, when the user operates the elbow pillow base 100 to rotate around the fixed rotating shaft 900 through the connector 200, the elastic element 400 will output the corresponding damping force based on the new initial pre-tightening torque, thereby realizing the stepless adjustment of the opening and closing speed of the elbow pillow.

[0102] In summary, the existing technology of split-type sub-dashboard elbow rests suffers from uncontrollable opening speed, easily resulting in opening too quickly or too slowly. Opening too quickly may pose a safety hazard due to passenger misoperation, while opening too slowly affects efficiency, reduces practicality, and leads to a poor overall user experience.

[0103] This application provides an elbow rest structure and vehicle. By setting multiple different limiting grooves 500 on the adjusting member 300 to cooperate with the compression elastic member 400, the elastic member 400 outputs different elastic forces to drive the elbow rest base 100, thereby achieving precise control of the rotation speed of the elbow rest base 100, solving the problem of uncontrollable elbow rest opening speed in the prior art. By arranging the multiple limiting grooves 500 in a ring, the transition between adjacent limiting grooves 500 can be smoother, which helps to improve the introduction efficiency and adjustment continuity of the elastic member 400. This makes the adjustment process of the elastic member 400 more suitable for application scenarios that require high-frequency adjustment or long-term use, effectively extending the service life of the adjusting member 300 and the elastic member 400, and reducing maintenance costs. The arrangement of the limit grooves 500 from shallow to deep provides an orderly path for switching elastic force levels, making the feedback during elbow pillow adjustment more predictable and controllable. The first positioning mark 600 further enhances the visual recognition capability of the adjustment structure, helping to quickly determine the resistance range of the current adjustment position during adjustment, improving the user's or assembler's operational intuition and sense of control. The detachable adjustment component 300 improves the maintainability and modularity of the overall structure, facilitating later maintenance or replacement of the adjustment component 300 and reducing operating costs. By setting paired first and second positioning marks 600 on the elbow pillow base 100 and the adjustment component 300, the position of the limit groove 500 can be intuitively indicated. This design enhances the user's adjustment experience and facilitates precise calibration of the adjustment components during assembly, ensuring the normal operation of the elbow pillow adjustment function. By rotatably mounting the adjustment component 300 onto the elbow pillow base 100, the directional adjustment capability of the adjustment component 300 is enhanced. Users can customize the position of the limiting groove 500 according to their personal habits, further improving ergonomic adaptability. A locking structure ensures that the adjustment component 300 remains stable after adjustment, enhancing the reliability of the output resistance between the adjustment component 300 and the elastic element 400, preventing malfunctions or loosening of the adjustment component 300 during use. The locking groove 700 and the locking element's engagement structure effectively prevent unexpected rotation of the adjustment component 300 due to vibration or misoperation, improving structural integrity. Stability and safety; the cooperation between the locking groove 700 and the locking component also prevents the adjusting component 300 from disengaging and rotating under the reaction force of the elastic component 400, improving the connection reliability between the adjusting component 300 and the elbow rest base 100, ensuring that the cooperation position between the limiting groove 500 and the elastic component 400 remains stable, and avoiding the failure of the output resistance of the elastic component 400 due to the rotation of the adjusting component 300; by setting the mounting groove 800 to accommodate the adjusting component 300, the movement of the adjusting component 300 relative to the elbow rest base 100 in the direction perpendicular to its rotation axis is restricted, making it easier for the elbow rest base 100 to directly restrict the adjusting component 300 as a whole, avoiding local friction between the adjusting component 300 and the adjusting component 300 rotation axis to cause excessive wear, and improving the service life of the adjusting component 300 rotation axis;Through the cooperation of the connecting part 401, the elastic part 402, and the abutting part 403, variable control of the rotational resistance between the adjusting member 300 and the rotating member is achieved. The elastic part 402 is responsible for mechanical response, the connecting part 401 ensures stable assembly, and the abutting part 403 achieves precise contact and guidance. The overall structure optimizes the adjustment performance and improves the smoothness and response accuracy of the elbow pad base 100's rotational control. By setting the limiting part 404, the positioning effect of the elastic member 400 within the limiting groove 500 is significantly enhanced, effectively preventing the abutting part 403 from disengaging from the limiting groove 500 due to uneven force or external disturbance during dynamic operation, thus improving the overall structural safety and durability. Simultaneously, the user or assembler can easily move the abutting part 403 away from or towards the adjusting member 300 through the limiting part 404, thereby facilitating the adjustment of the fit between the elastic member 400 and the adjusting member 300, and consequently adjusting the elbow pad's rotational resistance.
