Description

Technical Field

[0001] This application relates to the field of automotive accessories technology, and in particular to a floating table for automotive cup holders. Background Technology

[0002] In-vehicle cup holders are generally used to hold insulated cups. To meet the needs of passengers for working, dining, and entertainment in the vehicle, a small table can be configured through an external cup holder support device. However, traditional cup holder support devices are mostly fixed structures and cannot be radially extended and adapted according to the size of the cup or user needs, resulting in unstable placement or poor compatibility. Although the small table can be unfolded, the adjustment angle is limited, making it difficult to simultaneously meet the different usage needs of users for dining, working, and placing items. Utility Model Content

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0037] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0038] Example 1

[0039] Figure 1 This is a schematic diagram of the structure of the vehicle-mounted cup holder floating table shown in an embodiment of this utility model.

[0040] See Figure 1 and Figure 2 The vehicle-mounted cup holder floating table provided in this embodiment of the utility model includes a base 1, a telescopic component 2, a drive component 3, a cantilever component 4, a rotary joint 5, and a shelf 6.

[0041] The base 1 is a cylindrical shell structure with an axially extending receiving cavity inside. At least three sliding grooves 10 connected to the receiving cavity are distributed circumferentially in the cavity. The sliding grooves 10 are arranged radially to limit the movement path of the sliders 23. The circumferential support of the cup groove is achieved through the cooperation of multiple sliders 23.

[0042] The telescopic assembly 2 is used to provide adaptive support for the sidewall of the cup holder. The shelf 6 is fixed inside the vehicle via the telescopic assembly 2. The telescopic assembly 2 includes a rotating rod 20, a nut 21, a transmission plate 22, and a slider 23. The rotating rod 20 passes through the top end face of the base 1, and its lower end is threadedly connected to the nut 21. The two ends of the transmission plate 22 are hinged to the nut 21 and the slider 23 respectively, specifically using a ball joint connection. The fixed end of the ball joint is bolted to the nut 21 and the slider 23, and the free end is connected to the transmission plate 22. The nut 21, the transmission plate 22, and the slider 23 form a dynamic triangular transmission mechanism, that is, the moving path of the nut 21 is the fixed right-angle side, and the transmission plate 22 changes to the hypotenuse or the other right-angle side as the nut 21 moves. The rotation of the rotating rod 20 drives the nut 21 to move axially, which in turn drives the slider 23 to move radially along the slide groove 10, realizing stepless adjustment of the cup holder support diameter.

[0043] The drive component 3 is used to switch the hypotenuse of the aforementioned dynamic triangular transmission mechanism. Specifically, the drive component 3 can be operated manually or mechanically. When operated manually, a knob can be installed at the extended end of the rotating rod 20, allowing the user to adjust the displacement of the slider 23 by rotating the knob. When operated mechanically, a micro motor is installed inside the cavity, driving the rotating rod 20 to rotate via gear transmission. The top surface of the base 1 has a suitable operation panel, and the base 1 also has a power socket connected to the micro motor or a built-in rechargeable power supply.

[0044] The cantilever assembly 4 is mounted on the rotating rod 20 via a first bearing. The cantilever assembly 4 is mounted in the middle section of the rotating rod 20 via the first bearing, that is, between the top end face of the drive assembly 3 and the base 1. The cantilever assembly 4 can rotate freely around the axis of the rotating rod 20. The fixed end of the rotary joint 5 is connected to the cantilever assembly 4, and the free end is connected to the shelf 6 via a spline structure, allowing the shelf 6 to rotate 360° in the horizontal plane and be tilted at multiple angles. The surface of the shelf 6 is provided with an anti-slip silicone layer, and the horizontal working surface can stably support mobile devices, tableware and other items.

[0045] Compared with existing technologies, the vehicle-mounted cup holder floating table provided in this embodiment 1 uses a rotating rod 20 to drive the nut 21 to move axially, causing the slider 23 to extend and retract radially along the slide groove 10, forming a dynamic triangular support structure. This structure can adapt to cups of different diameters or irregularly shaped cup holders, improving compatibility and stability. Simultaneously, the multi-slide groove design provides uniform circumferential support, avoiding tilting caused by uneven force on one side. Furthermore, the cantilever assembly 4 is connected to the rotating rod 20 via a first bearing, allowing the shelf 6 to rotate axially around the rotating rod 20; the rotary joint 5 provides multi-angle adjustment at the free end, allowing the horizontal working surface of the shelf 6 to flexibly adapt to dining, office, and other scenarios.

[0046] Example 2

[0047] Based on Embodiment 1, in order to improve the portability of the floating table, Embodiment 2 of this application further refines the design of the cantilever assembly 4, the rotary joint 5, and the shelf 6. The cantilever assembly 4 of this application includes a first cantilever 40 and a second cantilever 41. The first cantilever 40 is hinged to the second cantilever 41 through a first hinge 42. The first cantilever 40 is provided with a rotating hole 40a, and the rotating hole 40a is provided with a first bearing. The inner ring of the first bearing is fitted with a rotating rod 20. The rotation direction of the second cantilever 41 is perpendicular to the axis of the rotating rod 20.

[0048] Specifically, the first cantilever 40 and the second cantilever 41 are hinged by a first hinge 42, with the hinge axis perpendicular to the axis of the rotating rod 20, achieving two-stage folding. The cantilever can rotate 0° to 180° around the hinge axis, allowing the storage plate 6 to be stored to the side of the base 1. The first cantilever 40 rotates 360° around the axis of the rotating rod 20 via a first bearing inside the rotating hole 40a, adapting to the interior space layout to facilitate dining or working within the vehicle. The first bearing can be a deep groove ball bearing, with an interference fit between the inner ring and the rotating rod 20, and a clearance fit between the outer ring and the rotating hole 40a, ensuring smooth rotation of the cantilever without axial movement.

[0049] Furthermore, the rotary joint 5 includes a spline sleeve 50, a spline shaft 51, a second bearing 52, and a keycap 53. The spline sleeve 50 has a spline groove that is clearance-fitted with the spline shaft 51. The spline shaft 51 is connected to the inner ring of the second bearing 52 via a bearing housing. The keycap 53 is connected to the outer ring of the second bearing 52 via a locking bolt, and the keycap 53 is connected to the shelf plate 6. The second bearing 52 can be an angular contact ball bearing, which is fixed to the end of the second cantilever 41 via a bearing housing. The outer ring and the keycap 53 are pre-tightened by the locking bolt to eliminate rotational clearance.

[0050] Furthermore, the shelf 6 includes a mounting plate 60, a support plate 61, a first panel 62, and a second panel 63. The first panel 62 and the second panel 63 are hinged together by a second hinge 64. The mounting plate 60 is connected to the first panel 62 by the fixed end of the second hinge 64. The support plate 61 is bolted to the mounting plate 60 and the first panel 62. The thickness of the second hinge 64 is the same as the thickness of the support plate 61. The free end of the rotary joint 5 is connected to the end face of the mounting plate 60 facing away from the first panel 62.

[0051] Specifically, the shelf 6 has an unfolded state and a folded state. The first panel 62 and the second panel 63 are unfolded to form the largest working surface through the second hinge 64. The support plate 61 is used to cooperate with the second hinge 64 to maintain the first panel 62 and the second panel 63 at the same level. The second hinge 64 and the support plate 61 are both connected to the mounting plate 60 and the first panel 62 by stainless steel bolts.

[0052] In this embodiment, the storage panel 6 achieves adaptive storage through a two-stage hinge structure, saving more space compared to traditional single-hing designs. Simultaneously, the spline-bearing composite rotary joint 5 provides bidirectional angle locking, offering advantages such as high adjustment precision and excellent operational feel. Furthermore, the foldable design and multi-angle adjustable features of the storage panel 6 can adapt to different usage needs, significantly improving the utilization of interior space.

[0053] Example 3

[0054] To improve the support stability of the device, Embodiment 3 of this application also designs a corresponding structure. Based on Embodiment 1 above, please refer to... Figures 1-3 The base 1 of Embodiment 3 of this application includes a base plate 11, an end plate 12 and at least three blocking posts 13. The blocking posts 13 are arranged in a circular array around the center of the rotating rod 20, and the two ends of the blocking posts 13 are connected to the base plate 11 and the end plate 12 respectively to form the receiving cavity. The sliding groove 10 is formed between adjacent blocking posts 13.

[0055] Furthermore, the base 1 also includes a pressure plate 14, which is disposed between the end plate 12 and the blocking post 13. The pressure plate 14 is connected to the blocking post 13 by evenly distributed fastening bolts, and a sandwich cavity is formed between the pressure plate 14 and the end plate 12.

[0056] Furthermore, a positioning pad 15 is provided at the bottom of the receiving cavity. The positioning pad 15 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.

[0057] Specifically, the base plate 11 and the four blocking posts 13 are integrally formed by injection molding. The blocking posts 13 are arranged in a 90° circumferential array around the center of the rotating rod 20. Adjacent blocking posts 13 form a guide channel for the slider 23, restricting the slider 23 to move only radially. The pressure plate 14 and the end plate 12 are both stainless steel stamping parts, and the blocking posts 13 are connected by 8 sets of M5 evenly distributed bolts. A ring can be set on the top end face of the pressure plate 14, so that a sandwich cavity is formed between the end plate 12 and the pressure plate 14.

[0058] Furthermore, the drive assembly 3 is a knob, which is fitted onto the extended end of the rotating rod 20 and locked with screws. The outer periphery of the knob is provided with anti-slip texture. The cantilever assembly 4 is located between the knob and the end plate 12. The outer surface of the slider 23 and the bottom of the base plate 11 are both provided with anti-slip pads.

[0059] Furthermore, the vehicle-mounted cup holder floating table also includes a self-locking component 7, which includes a ratchet 70, a fixed shaft 71, a torsion spring 72, and a pawl 73. The outer periphery of the rotating rod 20 is provided with a circumferential rib 20a and the ratchet 70. The circumferential rib 20a is located in the interlayer cavity, and the ratchet 70 is located in the receiving cavity. The end face diameter of the ratchet 70 is equal to the diameter of the rotating rod 20.

[0060] The fixed shaft 71 is located in the receiving cavity, 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.

[0061] When the circumferential rib 20a abuts against the pressure plate 14, the pawl 73 engages and locks with the ratchet 70; when the circumferential rib 20a disengages from the pressure plate 14, the pawl 73 disengages from the ratchet 70.

[0062] 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., driving the nut 21 to move upward), the pawl 73 can slide circumferentially on the ratchet 70. When rotating in the reverse direction or stopping, the ratchet 70 engages with the pawl 73, thus preventing 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, facilitating the pawl 73 to quickly re-engage with the outer periphery of the ratchet 70 after disengaging from it.

[0063] The fixed shaft 71 is installed and fixed in the receiving cavity. The fixed shaft 71 is integrally formed with the base 1. 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.

[0064] A circumferential rib 20a is provided on the outer periphery of the rotating rod 20 and located in the interlayer cavity. The rotating rod 20 can move along its own axis in the interlayer cavity. The ratchet 70 moves axially along with the rotating rod 20. The user can pull the rotating rod 20 upward a certain distance by pulling the knob. At this time, the circumferential rib 20a abuts against or is close to the end plate 12, and the ratchet 70 disengages from the pawl 73. When the rotating rod 20 reverses, the pawl 73 does not hinder the rotation of the ratchet 70, thus making it convenient for the user to release the support of the cup groove.

[0065] 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.

[0066] Example 4

[0067] The difference between Example 4 and Example 3 is that Example 4 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 alternating layers of pads and damping washers. The end plate 12 and the pressure plate 14 can relatively compress the damping washers.

[0068] 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 14 and the end plate 12 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.

[0069] 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 14 and the end plate 12. The other structures and working principles of this embodiment 4 are the same as those of embodiment 3, and will not be repeated here.

[0070] The various embodiments of this application 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.
