[0031] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0032] Example 1

[0033] Figure 1 This is a schematic diagram of the structure of the vehicle-mounted cup holder support device shown in an embodiment of this utility model. Figure 2 This is an exploded view of the vehicle-mounted cup holder support device shown in an embodiment of this utility model.

[0034] See Figure 1 and Figure 2 The vehicle cup holder support device provided in this embodiment includes a base 1, a telescopic component 2, and a drive component 3. The base 1 is a container for adapting to the cup holder of a four-wheeled car or electric bicycle, and is fixedly placed by the telescopic component 2. The drive component 3 is used to provide adaptive support for the telescopic component 2.

[0035] The base 1 is a cylindrical shell with an internal cavity 10 and at least one circumferentially distributed groove 11. When there is only one groove 11, the slider 23 and the outer side of the base 1 together form a support for the side wall of the cup groove; when there are two or more grooves 11, each channel is evenly arranged around the center of the cavity 10, and circumferential support is achieved through the cooperation of multiple sliders 23.

[0036] The telescopic assembly 2 includes a rotating rod 20, a nut 21, a transmission rod 22, and a slider 23. The first end of the rotating rod 20 has a threaded structure, passing through the top end face of the base 1 and threadedly connected to the nut 21. When the rotating rod 20 rotates, it drives the nut 21 to move axially. The nut 21 and slider 23 are hinged via the transmission rod 22. The horizontal plane where the hinge point of the slider 23 and the transmission rod 22 is located is flush with the highest movable point of the nut 21. Under this configuration, a dynamic triangular transmission structure is formed between the nut 21, the transmission rod 22, and the slider 23. That is, the moving path of the nut 21 is a fixed right-angled side, and the transmission rod 22 changes to the hypotenuse or the other right-angled side as the nut 21 moves. The slider 23 is limited by the slide groove 11, and the support amplitude is precisely controlled through trigonometric functions. The slider 23 is controlled to move radially along the base 1 within the slide groove 11, thereby achieving expanded support or retraction.

[0037] The drive component 3 is used to realize the above-mentioned dynamic triangular transmission structure, which can be implemented by manual operation or mechanical transmission. When implemented by manual operation, a knob can be set at the exposed end of the rotating rod 20, and the displacement of the slider 23 is adjusted by rotating the knob; when implemented by mechanical transmission, a micro motor is set in the receiving cavity 10, which drives the rotating rod 20 to rotate through gear transmission. The top end face of the base 1 is provided with a matching operation panel, and the base 1 is also provided with a power socket connected to the micro motor or a built-in rechargeable power supply.

[0038] In this embodiment, the rotary drive assembly 3 (knob or motor) drives the rotating rod 20 to rotate circumferentially, and the nut 21 moves linearly along the axis of the rotating rod 20. Through the transmission rod 22, the slider 23 is pushed radially outward or inward to precisely fit the side wall of the cup groove of different sizes.

[0039] Compared with existing technologies, the vehicle-mounted cup holder support device provided by this utility model eliminates the problem of elastic decay caused by long-term pressure by replacing elastic elements with a rigid transmission structure. Furthermore, the overall structure is compact, significantly reducing maintenance costs. Simultaneously, the use of threaded transmission combined with a triangular linkage mechanism ensures stable transmission of support force and avoids stress concentration on one side. In addition, this utility model can be designed with both manual and mechanical drive modes to meet diverse user operating needs.

[0040] Example 2

[0041] To improve the support stability of the vehicle cup holder support device, Embodiment 2 of this application also designs a corresponding structure. Based on Embodiment 1 above, please refer to... Figure 2 and Figure 3 In Embodiment 2 of this application, there are four slide grooves 11 and four sliders 23, with each slide groove 11 corresponding to one slider 23. The slider 23 has a cuboid shell structure and is housed within the slide groove 11. The two ends of the transmission rod 20 can be connected to the slider 23 and the nut 21 by ball joints. The slider 23 has two hinge points on the side facing the rotating rod 20, and each hinge point is hinged to a rotating rod 20. Correspondingly, the nut 21 has four mounting ears evenly distributed around its circumference, and each mounting ear consists of two mounting blocks. The shape of the slide groove 11 is adapted to the slider 23, and the four sliders 23 constitute a four-way support structure. This four-way support structure can improve overall stability, adapt to circular or square cup grooves, and prevent tilting caused by uneven force on one side.

[0042] Furthermore, the base 1 includes a base plate 12, an end plate 13, and four blocking posts 14. The four blocking posts 14 are arranged in a circular array around the center of the rotating rod 20, and the two ends of the blocking posts 14 are connected to the base plate 12 and the end plate 13 respectively to form the receiving cavity 10. The sliding groove 11 is formed between adjacent blocking posts 14. The base plate 12 and the four blocking posts 14 are integrally formed by injection molding. The end plate 13 is a flat circular plate with an annular flange on the outer edge of its end face facing the base plate 12. The annular flange is used to suspend the end plate 13 so that other functional components can be placed between the end plate 13 and the blocking posts 14. The end plate 13 has a threaded hole through which a bolt passes, and the bolt is threadedly connected to the blocking post.

[0043] Furthermore, the base 1 also includes a pressure plate 5 and a cantilever 6. The pressure plate 5 is disposed between the end plate 13 and the blocking post 14, and the cantilever 6 is disposed between the end plate 13 and the drive assembly 3. The pressure plate 5 is connected to the blocking post 14 by fasteners, and a sandwich cavity is formed between the pressure plate 5 and the end plate 13. The cantilever 6 is used to connect external equipment.

[0044] Furthermore, the bottom of the receiving cavity 10 is provided with a positioning pad 15, which has a positioning groove that is adapted to engage with the end of the rotating rod 20. With this setting, the rotating rod 20 can be installed accurately, reducing shaking during rotation and improving transmission efficiency.

[0045] Furthermore, the drive component 3 is a knob, which is fitted onto the extended end of the rotating rod 20 and locked with a screw. The user can manually operate the knob, which provides intuitive rotational feedback for easy and quick adjustment.

[0046] Furthermore, the outer periphery of the knob is provided with anti-slip texture, which can improve the user's operating feel and prevent slippage. The outer surface of the slider 23 and the bottom of the base 1 are provided with anti-slip pads 4, which can increase friction and prevent the device from sliding when the vehicle is bumpy, thus improving the reliability of the support.

[0047] Based on the above specific implementation, in order to prevent the rotating rod 20 from accidentally reversing and causing the slider 23 to retract, and to improve the stability of the device under vehicle bumps or external interference, the vehicle cup holder support device also includes a self-locking component 7, which includes a ratchet 70, a fixed shaft 71, a torsion spring 72 and a pawl 73.

[0048] The outer periphery of the rotating rod 20 is provided with a circumferential rib 200 and a ratchet 70. The circumferential rib 200 is located in the interlayer cavity, and the ratchet 70 is located in the receiving cavity 10. The end face diameter of the ratchet 70 is equal to the diameter of the rotating rod 20.

[0049] The fixed shaft 71 is disposed in the receiving cavity 10, and the pawl 73 and the torsion spring 72 are sleeved on the fixed shaft 71. One end of the torsion spring 72 is connected to the fixed shaft 71, and the other end is connected to the pawl 73.

[0050] When the circumferential rib 200 abuts against the pressure plate 5, the pawl 73 engages and locks with the ratchet 70; when the circumferential rib 200 disengages from the pressure plate 5, the pawl 73 and the ratchet 70 disengage.

[0051] The ratchet 70 is located on the outer periphery of the rotating rod 20. Its tooth profile is designed to be unidirectionally inclined. When the rotating rod 20 rotates forward to support the cup groove (i.e., the nut 21 moves upward), the pawl 73 can slide circumferentially on the ratchet 70 without affecting the rotation of the rotating rod 20. After reverse rotation or when rotation stops, the ratchet 70 engages with the pawl 73, thus restricting the rotating rod 20 from reversing. The ratchet 70 and the rotating rod 20 are integrally formed, specifically by metal powder injection molding and sintering. The end face diameter of the ratchet 70 is equal to the diameter of the rotating rod 20, allowing the pawl 73 to quickly re-engage with the ratchet 70's tooth surface after disengaging from it.

[0052] The fixed shaft 71 is installed and fixed in the receiving cavity 10. It can be integrally molded by injection molding. The fixed shaft 71 serves as the mounting base for the pawl 73 and the torsion spring 72. The torsion spring 72 is sleeved on the fixed shaft 71. One end of the torsion spring 72 is connected and fixed to the fixed shaft 71, and the other end is connected and fixed to the pawl 73. The torsion spring 72 can provide the pawl 73 with a continuous elastic force pressing against the ratchet 70, ensuring that the pawl 73 can smoothly engage with the ratchet 70. The head shape of the pawl 73 meshes with the ratchet 70 to form a one-way locking.

[0053] The circumferential rib 200 is located on the outer periphery of the rotating rod 20 and within the interlayer cavity. When the rotating rod 20 is manually pulled, the rotating rod 20 can move along its own axial direction, that is, the circumferential rib 200 moves axially within the interlayer cavity. The ratchet 70 moves axially along with the rotating rod 20. By pulling the axial drive assembly 2, the locking state can be released. At this time, the circumferential rib 200 can be separated from the bottom plate 5 and moved to abut against or near the end plate 13. At this time, the ratchet 70 disengages from the pawl 73, and the user can reverse the rotating rod 20 to retract the slider 23 into the slide groove 11, thereby releasing the circumferential support of the telescopic assembly 2 on the cup groove.

[0054] In this embodiment, mechanical engagement prevents the rotating rod 20 from accidentally reversing when the vehicle is bumpy, ensuring stable support. It can be unlocked simply by pulling the knob, without the need for complicated tools or additional operating steps, thus achieving reliable locking and convenient unlocking of the device and significantly improving the stability of the vehicle cup holder support device under complex working conditions.

[0055] Example 3

[0056] The difference between Embodiment 3 and Embodiment 2 is that Embodiment 3 uses a damping component (not shown) to replace the self-locking component 7. The damping buffer design provides resistance to suppress the rotation of the rotating rod 20 and provides an operational damping feel. The damping component is sleeved on the rotating rod 20 and located in the interlayer cavity. The damping component includes alternately stacked pads and damping washers. The end plate 13 and the pressure plate 5 can relatively compress the damping washers.

[0057] The gaskets are made of metal materials, such as stainless steel sheets, and the damping washers are made of elastic materials, such as silicone or polyurethane. The gaskets and damping washers are stacked alternately. The inner diameter of the gaskets and washers is adapted to the outer diameter of the rotating rod 20 to ensure that they are tightly fitted onto the rotating rod 20. The outer diameter can be determined according to the number and thickness of the gaskets and damping washers. The more gaskets and damping washers are set, the smaller the outer diameter of the gaskets and damping washers will be, so as to form an effective self-locking resistance in the interlayer cavity. By tightening the bolts, the pressure plate 5 and the end plate 13 apply axial pressure to the damping washers, causing them to undergo radial deformation, thereby providing resistance to suppress the rotation of the rotating rod 20. Combined with the thread self-locking characteristics of the rotating rod 20 and the nut 21, double self-locking is achieved.

[0058] Furthermore, the resistance of the damping assembly can be adjusted by changing the axial pressure on the damping washer by adjusting the tightness of the bolts between the pressure plate 5 and the end plate 13. The other structures and working principles of this embodiment 3 are the same as those of embodiment 2, and will not be repeated here.

[0059] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
