[0039] In existing technologies, traditional vehicle interior door handles are typically fixed to the vehicle body using a rigid connection. When subjected to external forces, the handle 4 is prone to irreversible deformation in certain areas, resulting in uneven surface defects. Furthermore, the fit clearance between the handle 4 and the mounting structure is difficult to control precisely, and loosening or displacement may occur after long-term use, further exacerbating the appearance problems.

[0040] Therefore, as Figure 1 As shown, this application proposes an interior handle, including a mounting base 1, a first connecting shaft 2, a second connecting shaft 3, a handle 4, and a transmission assembly 5. The mounting base 1 is provided with a receiving groove 11, a first guide groove 12, and a second guide groove 13; the first connecting shaft 2 passes through the first guide groove 12 and moves along its extension direction; the second connecting shaft 3 passes through the second guide groove 13 and moves along its extension direction; the handle 4 is received in the receiving groove 11 and its two ends are respectively connected to the first connecting shaft 2 and the second connecting shaft 3; the transmission assembly 5 is provided on the mounting base 1 and connects the first connecting shaft 2 and the second connecting shaft 3. When the handle 4 is deformed by external force, the middle part protrudes out of the receiving groove 11, and the first connecting shaft 2 and the second connecting shaft 3 move towards each other.

[0041] The receiving groove 11 refers to the recessed structure on the mounting base 1 for accommodating the handle 4. Specifically, it can be formed using injection molding, with its depth matching the thickness of the handle 4. This structure provides a stable storage space for the handle 4, ensuring that it is completely embedded in the groove when not in use, avoiding visual clutter caused by exposed parts. The first guide groove 12 and the second guide groove 13 refer to the linear slide rail structure on the mounting base 1, which can be processed using metal insert slotting or mold forming methods. Their extension direction is consistent with the movement path of the connecting shaft. The guide grooves constrain the movement direction of the connecting shaft, ensuring the controllability of the displacement trajectory at both ends of the handle 4 during deformation. The transmission component 5 refers to the power transmission mechanism connecting the first connecting shaft 2 and the second connecting shaft 3. Specifically, it can adopt a gear and rack meshing structure, with the rotating gear 51 meshing with the first rack 52 and the second rack 53 on both sides respectively. This component achieves synchronous reverse movement of the first connecting shaft 2 and the second connecting shaft 3 through mechanical linkage, eliminating the twisting deformation of the handle 4 caused by unilateral displacement deviation.

[0042] Specifically, when an external force is applied to the handle 4, the handle 4 undergoes an outward elastic deformation. At this time, the rotating gear 51 in the transmission assembly 5 begins to rotate under the opposing forces of the first rack 52 and the second rack 53, forcing the first connecting shaft 2 to move along the first guide groove 12 and the second connecting shaft 3 to move along the second guide groove 13. The opposing movement of the first connecting shaft 2 and the second connecting shaft 3 releases the displacement space at both ends of the handle 4, causing the deformation to concentrate in the middle area and form a uniform outward convexity. After the external force disappears, the reset component 54 in the transmission assembly 5 pushes the rack to reset, and the first connecting shaft 2 and the second connecting shaft 3 move in opposite directions, causing the handle 4 to return to a straight state. During this process, the constraint effect of the guide groove on the movement path of the connecting shafts ensures that the handle 4 does not shift laterally during deformation, while the synchronous drive mechanism of the transmission assembly 5 ensures that the movement distance of the connecting shafts on both sides remains equal.

[0043] Through the above technical solution, this application achieves precise control of the deformation process of the handle 4, effectively eliminating surface unevenness caused by local stress concentration. The synergistic effect of the guide groove and the transmission component 5 ensures that the handle 4 only bulges outward uniformly in the middle area when under force, and is completely retracted into the mounting groove when not in use, significantly improving the flatness of the appearance. At the same time, this structure disperses the force through mechanical linkage, extending the service life of the handle 4 and the mounting base 1.

[0044] This application further proposes an interior door handle structure including two connecting portions 41 and one deformable portion 42. One connecting portion 41 is connected to a first connecting shaft 2, and the other connecting portion 41 is connected to a second connecting shaft 3. One end of the deformable portion 42 is connected to one connecting portion 41, and the other end is connected to the other connecting portion 41. When the two connecting portions 41 are close together, the deformable portion 42 deforms to protrude outward from the receiving groove 11.

[0045] The connecting part 41 is a structural component that is fixedly connected to the connecting shaft and transmits motion. It can be made of rigid plastic or metal, and the rigid connection ensures that the connecting shaft moves synchronously with the connecting part 41. The deformable part 42 is a flexible structure with elastic deformation capabilities, which can be made of rubber, silicone, or elastic polymer materials. It achieves the transformation from a straight line to an arc-shaped protrusion through the material's own deformation characteristics. The detachable connection refers to a connection structure achieved through snap-fit, screw, or magnetic attraction. Specifically, it can be achieved using a quick-plug interface, facilitating the individual replacement of the deformable part 42 or the connecting part 41.

[0046] Specifically, when an external force is applied to the handle 4, the two connecting parts 41 are respectively subjected to the traction force of the first connecting shaft 2 and the second connecting shaft 3. Due to the linkage of the transmission assembly 5, the two connecting parts 41 are displaced in opposite directions, and the two ends of the deformable part 42 are subjected to tensile forces in opposite directions. At this time, under the combined action of longitudinal compression and lateral tension, the middle area of ​​the deformable part 42 bends outward due to the material's ductility, forming a protrusion with a predetermined arc. The use of rigid material for the connecting parts 41 can avoid transmission errors caused by their own deformation, while the flexible material of the deformable part 42 ensures durability under repeated deformation. When maintenance or replacement is required, the detachable structure of the deformable part 42 and the connecting parts 41 allows for the individual disassembly of the damaged parts without the need to replace the entire handle 4.

[0047] Through the above technical solution, this application achieves precise control of the deformation process of the handle 4, avoiding asymmetric deformation caused by local stress concentration. The separate structure of the deformation part 42 and the connecting part 41 simplifies the replacement operation of the flexible component.

[0048] This application further proposes that the deformable part 42 and the two connecting parts 41 are detachably connected.

[0049] The detachable connection refers to the separable mechanical connection between the deformable part 42 and the connecting part 41, which can be achieved through a snap-fit ​​structure, a threaded structure, or a plug-in structure. The snap-fit ​​structure allows for quick assembly and disassembly through elastic engagement; the threaded structure achieves fastening and disassembly by tightening the threads; and the plug-in structure achieves positioning and locking through the engagement of protrusions and grooves. These structures ensure stability during normal use while allowing for component separation during maintenance. The detachable feature makes the deformable part 42 an independent module, avoiding permanent fixation to the connecting part 41, thus solving the problem of overall replacement.

[0050] Specifically, when the deformable part 42 fractures due to fatigue from repeated deformation, the damaged deformable part 42 can be directly removed from the two connecting parts 41 by releasing the clip, loosening the threads, or pulling out the plug-in structure. At this time, the connecting parts 41 maintain their original assembly relationship with the first connecting shaft 2 and the second connecting shaft 3, and only the new deformable part 42 needs to be replaced to restore function. This process does not require disassembling the entire handle 4 structure, nor does it require adjusting the gear and rack meshing relationship of the transmission assembly 5, significantly shortening maintenance time. For example, when using a plug-in structure, plug-in connectors with guide protrusions can be provided at both ends of the deformable part 42, and guide grooves can be opened at corresponding positions on the connecting parts 41. During installation, axial pushing is sufficient to complete positioning and fixation.

[0051] Through the above technical solution, this application effectively reduces the maintenance cost of the vehicle interior handle and avoids the problem of overall scrapping due to partial damage. Maintenance personnel can quickly replace the deformable part 42 without disassembling the mounting base 1 and transmission assembly 5, reducing disassembly and assembly damage to the vehicle interior during maintenance. Furthermore, the modular design improves the reusability of parts; deformable parts 42 of different specifications can be adapted to the same set of connecting parts 41, enhancing product configurability.

[0052] This application further proposes that the interior handle also includes a limiting block 6, which is disposed in the receiving groove 11 and has a limiting groove 61, at least a portion of the deformable part 42 being adapted to be housed in the limiting groove 61.

[0053] The limiting block 6 is a rigid structure fixed within the receiving groove 11, which can be made of injection-molded plastic or metal and is fixedly connected to the mounting base 1 by clips or screws. The limiting groove 61 is a groove structure extending along the length of the deformable part 42, which can be designed with an arc or U-shaped cross-section, and its width is slightly larger than the thickness of the deformable part 42 to allow the deformable part 42 to slide. The bottom surface is an arc-shaped surface that is high in the middle and low at both ends, which can be formed by a parabola or circular arc curve, and is used to provide guidance when the deformable part 42 moves.

[0054] Specifically, when the handle 4 is in the retracted state, the middle section of the deformable part 42 is embedded in the limiting groove 61, and the bottom arc surface contacts the lower surface of the deformable part 42. This structural constraint prevents the deformable part 42 from sag due to its own weight and causing localized bulging. When an external force is applied to the handle 4, the deformable part 42 is pulled outward by the connecting parts 41 on both sides. At this time, the side walls of the limiting groove 61 guide the deformable part 42 to bend along a predetermined path, and the bottom arc surface forces the middle section of the deformable part 42 to maintain an upward arched structure, thereby avoiding multi-point bending or wavy deformation. After the deformable part 42 is fully protruding, the side wall at the opening end of the limiting groove 61 restricts the further lateral expansion of the deformable part 42, ensuring the symmetry of the protrusion shape.

[0055] Through the above technical solution, this application achieves complete flushing between the deformable part 42 and the surface of the mounting base 1 when the handle 4 is in the stored state, eliminating visual defects caused by local warping; during the unfolding process, the deformable part 42 always bends evenly along the predetermined trajectory of the limiting groove 61 to form a smooth and continuous arc-shaped protrusion, avoiding creases or wave-shaped deformations that may occur in traditional solutions, and significantly improving the appearance consistency of the handle 4 during operation.

[0056] This application further proposes that the limiting groove 61 extends along the length direction of the deformable part 42, and the limiting groove 61 has a bottom surface facing the opening of the limiting groove 61. The bottom surface is an arc-shaped surface that is high in the middle and low at both ends in the extending direction of the limiting groove 61.

[0057] The extension of the limiting groove 61 along the length direction of the deformable part 42 means that the length direction of the limiting groove 61 is consistent with the length direction of the deformable part 42. Specifically, it can be achieved by using a straight or wavy groove that matches the bending trajectory of the deformable part 42, so that the deformable part 42 always moves along the groove trajectory during movement. The arc-shaped bottom surface that is high in the middle and low at both ends means that the bottom of the limiting groove 61 has a convex arc-shaped structure. Specifically, it can be formed by CNC machining or injection molding, and the radius of curvature of the arc-shaped surface is consistent with the curvature of the deformable part 42 in its natural bending state.

[0058] Specifically, when the handle 4 is subjected to external force, the deformable part 42 is squeezed into the limiting groove 61 and slides. At this time, the middle protrusion of the arc surface applies a guiding force to both sides to the deformable part 42, forcing the deformable part 42 to bend evenly along the length of the groove, avoiding surface wrinkles caused by local displacement. When the external force disappears, the deformable part 42 is guided by the inclined structure on both sides of the arc surface during the reset process, automatically sliding to the middle of the limiting groove 61 and restoring its flat and stored state.

[0059] Through the above technical solution, this application can effectively prevent the deformable part 42 from becoming uneven due to positional displacement during storage. At the same time, the guiding effect of the arc surface improves the reset stability of the deformable part 42, ensuring that the handle 4 can maintain a flat appearance after multiple uses.

[0060] This application further proposes a transmission assembly 5 including a rotating gear 51, a first rack 52, and a second rack 53. The rotating gear 51 is rotatably mounted on the mounting base 1. One end of the first rack 52 meshes with one side of the rotating gear 51, and the other end is connected to the first connecting shaft 2. One end of the second rack 53 meshes with the side of the rotating gear 51 opposite to the first rack 52, and the other end is connected to the second connecting shaft 3.

[0061] Among them, the rotating gear 51 refers to a transmission component with a circumferential tooth structure, which can be made of steel gear or engineering plastic gear. The rotation of the gear converts the linear motion of the racks on both sides into synchronous reverse motion. The first rack 52 and the second rack 53 refer to moving components with linear tooth structures, which can be made by metal stamping or injection molding. The driving force is transmitted through the meshing of the rack and the gear. The rotatable setting of the mounting base 1 means that the gear rotation is supported by a bearing or shaft hole mating structure, which can be implemented by stainless steel bushing or self-lubricating bearing.

[0062] Specifically, when the handle 4 is subjected to an external force, the first connecting shaft 2 drives the first rack 52 to move along the first guide groove 12. The first rack 52 drives the rotating gear 51 to rotate, and the rotation of the gear causes the second rack 53 to produce a displacement in the opposite direction to the movement of the first rack 52, thereby causing the second connecting shaft 3 to move towards the first connecting shaft 2. In this process, the equal diameter characteristic of the gears ensures that the movement distance of the racks on both sides is equal, and the meshing transmission between the gears and racks eliminates the clearance error that may exist in traditional linkage mechanisms. The symmetrical movement of the first connecting shaft 2 and the second connecting shaft 3 causes uniform deformation in the middle area of ​​the handle 4.

[0063] Through the above technical solution, this application effectively solves the problem of uneven surface caused by asynchronous transmission of traditional handle 4. The gear and rack transmission mechanism can accurately control the movement trajectory of the first connecting shaft 2 and the second connecting shaft 3, so that the middle part of handle 4 forms a smooth and continuous convex curved surface under the action of external force, avoiding local concave and convex defects.

[0064] This application further proposes to add a reset member 54 to the transmission assembly 5. The reset member 54 is installed on the mounting base 1 and connected to the first rack 52 or the second rack 53, and is used to drive the first rack 52 or the second rack 53 to move so that the first connecting shaft 2 and the second connecting shaft 3 are moved away from each other.

[0065] The reset element 54 is a mechanical component capable of storing and releasing elastic potential energy. It can be implemented using a helical spring, torsion spring, or elastic rubber body. Its fixed end is connected to the mounting base 1, and its movable end is connected to the end of the rack. When the rack is displaced by an external force, the reset element 54 undergoes elastic deformation and accumulates energy. After the external force disappears, the elastic restoring force drives the rack to move in the opposite direction, thereby resetting the connecting shaft.

[0066] Specifically, when an external force is applied to the handle 4, causing it to deform and bringing the first connecting shaft 2 and the second connecting shaft 3 closer together, the rotation of the rotating gear forces the first rack 52 and the second rack 53 to move synchronously in opposite directions. At this time, the reset member 54 is stretched or compressed, generating deformation and storing elastic potential energy. When the external force is removed, the elastic restoring force of the reset member 54 acts on the connected rack, pushing the rack to slide in the opposite direction, thereby driving the rotating gear to rotate in the opposite direction, causing the rack on the other side to move synchronously. The synchronous reverse movement of the two racks causes the first connecting shaft 2 and the second connecting shaft 3 to move away from each other, causing the deformed part 42 of the handle 4 to return to its initial flat state, avoiding residual protrusions.

[0067] Through the above technical solution, this application solves the problem of the handle 4 failing to automatically reset after deformation, resulting in uneven surface, allowing the handle 4 to quickly return to a flat state after the external force is removed, maintaining its appearance integrity. The reset component 54, connected to a single-sided rack, enables bidirectional drive, simplifying the transmission structure layout and improving the reliability of the reset action.

[0068] This application further proposes to install a damper between the rotating gear 51 and the mounting base 1.

[0069] The damper is a device that suppresses mechanical motion by generating resistance. Specifically, it can be a hydraulic damper or a viscous damper, filled with a viscous fluid or equipped with friction plates to generate resistance. The rotating gear 51 is a power transmission component that meshes with the first rack 52 and the second rack 53. It can be made of metal or engineering plastic and is mounted on the mounting base 1 via a shaft hole. The function of the damper is to absorb the kinetic energy of the gear rotation, reducing the vibration amplitude of the gear due to inertia or external impact, thereby preventing instantaneous impacts on the transmission assembly 5 during operation.

[0070] Specifically, when the handle 4 is subjected to an external force, the first connecting shaft 2 and the second connecting shaft 3 move towards each other, driving the first rack 52 and the second rack 53 to rotate the rotating gear 51. At this time, the damper limits the rotational speed of the gear through the resistance generated by the internal viscous fluid or friction plates, preventing the gear from rotating rapidly due to inertia. The rotational kinetic energy of the gear is gradually absorbed by the damper, thereby eliminating the vibration when the gear meshes with the rack and preventing abnormal noise or unstable movement caused by the vibration of the transmission component 5 during the deformation of the handle 4.

[0071] Through the above technical solution, this application effectively suppresses the vibration and impact when the gear and rack mesh, avoids abnormal noise or vibration caused by the motion inertia of the transmission component 5 during the operation of the handle 4, and at the same time reduces the mechanical wear of the gear and rack, extending the service life of the handle inside the vehicle.

[0072] Please refer to the reference. Figure 2 and Figure 3 This application further proposes that the interior handle also includes a mounting bracket 7 and a housing 8, with the mounting base 1 located on the mounting bracket 7 and the housing 8 covering the mounting base 1.

[0073] The mounting bracket 7 refers to the basic support structure used to support the mounting base 1. It can be implemented using a metal frame or injection-molded rigid components, and is connected to the vehicle body via bolts or clips, providing a stable mounting foundation for the mounting base 1 and preventing structural deformation under stress. The outer shell 8 refers to the external casing covering the mounting base 1. It can be made of ABS plastic or aluminum alloy and is integrally molded, covering the outside of the mounting base 1 via clips or screws, completely enclosing the mounting base 1 and its internal components, achieving a smooth appearance and internal protection.

[0074] Specifically, after the mounting bracket 7 is rigidly connected to the vehicle body, the mounting seat 1 is fixed to the mounting bracket 7 by welding or bolts, forming a double support structure. After the mounting seat 1 is assembled, the outer shell 8 completely covers its outer surface, eliminating gaps or protrusions at the connection between the mounting seat 1 and the vehicle body, so that the handle 4 has a complete and continuous smooth curved surface. The edges of the outer shell 8 and the mounting bracket 7 are seamlessly connected by sealing strips or chamfering design to prevent dust from entering the internal transmission components 5. When the handle 4 is in the retracted state, the closed structure of the outer shell 8 hides the guide groove and connecting shaft in the mounting seat 1, only exposing the outer surface of the deformable part 42 of the handle 4, thus achieving an integrated appearance.

[0075] In some specific embodiments, the fixing bracket 7 can be designed as a U-shaped groove structure, with the mounting base 1 embedded in the groove and fixed by the limiting protrusion; the inner wall of the outer shell 8 can be provided with guide ribs, which cooperate with the sliding groove on the outer wall of the mounting base 1 to ensure that the outer shell 8 does not shift after installation. For example, the surface of the outer shell 8 can be sprayed with a coating of the same color as the interior of the vehicle to further enhance visual uniformity.

[0076] Through the above technical solution, this application effectively eliminates the uneven appearance problem caused by the exposed mounting base 1 of the door handle, improves the overall structural rigidity, prevents external impurities from entering the transmission component 5, and facilitates the separate disassembly and maintenance of the outer shell 8, thereby reducing maintenance costs.

[0077] This application further proposes a vehicle body and an interior handle, with the interior handle located on the vehicle body.

[0078] The vehicle body refers to the load-bearing structure of the vehicle, which can be implemented using a metal frame or composite body structure. It provides a fixed installation position for the interior handle, ensuring a stable connection between it and the vehicle's main structure. The interior handle is a retractable and deformable operating component, which can be made of a material with elastic deformation capabilities, combined with guide grooves and a transmission mechanism. It is used to maintain a flush surface with the vehicle body when not in use, avoiding the surface unevenness problems caused by exposed or deformed structures in traditional mechanical handles.

[0079] Specifically, the vehicle body serves as the basic load-bearing structure, providing fixed support for the mounting base 1 of the handlebar inside the vehicle. The mounting base 1 houses the handlebar 4 body through the receiving groove 11. When an external force is applied to the handlebar 4, its deformable part 42 is compressed and deformed, with the middle part protruding outward to form an operating position. At the same time, the first connecting shaft 2 and the second connecting shaft 3 move towards each other along the guide groove, achieving synchronous displacement through the transmission assembly 5. After the external force is released, the reset member 54 in the transmission assembly 5 drives the connecting shaft to move in the opposite direction, causing the handlebar 4 to return to its retracted state. The deformable part 42 re-fits the inner wall of the receiving groove 11, keeping the surface of the vehicle body flat.

[0080] Through the above technical solution, this application solves the problem of uneven surfaces caused by mechanical structure or material deformation in traditional vehicle interior handles, achieving stable storage of handle 4 during vehicle operation while ensuring ease of operation. The deformation process of handle 4 is precisely controlled by guide grooves and transmission mechanisms, and it automatically returns to a flat state after resetting, improving the overall aesthetics and structural reliability of the vehicle interior.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
