Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle-mounted small table technology, and in particular to a vehicle-mounted small table that can be adapted to fix a vehicle-mounted water cup holder. Background Technology
[0002] Currently, most car water cup holders rely on a screw-on mechanism to fix the cup holder. The bottom of the cup holder has a spiral pattern that works in conjunction with a groove on the upper part of the internal telescopic support block. Screwing the cup holder causes the spiral pattern to engage with the groove, which in turn causes the telescopic support block to expand outward or retract inward (e.g., CN220700977U). However, this structure has its drawbacks. This type of structure uses a spiral drive to match multiple grooves at the bottom in a threaded manner, resulting in poor product durability. In addition, most of these products are made of plastic, and due to product tolerance issues, they are prone to jamming after prolonged use.
[0003] Secondly, the rise of in-car leisure and entertainment options, such as outdoor camping or waiting while charging, often involves setting up small tables to place items and relax. However, most of these small tables are currently only available in MPVs, while most SUVs and sedans do not. Adding small tables requires consideration of cost and flexibility. Installing tables via the back of the driver and passenger seats is very expensive and offers very limited flexibility, restricting use to a single person in a single direction. These issues urgently need to be addressed. Utility Model Content

Detailed Implementation
[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0042] refer to Figures 1 to 21 :
[0043] This embodiment discloses a small car table 20A adaptable to a car cup holder, including a telescopic support base 10A and a connecting arm 30A. The telescopic support base 10A includes a support shell 1, a screw 2, a nut sleeve 3, a connecting rod 44, a telescopic support body, and a knob 6. The inner side of the support shell 1 forms a receiving cavity 101. The top of the support shell 1 has a shell cover 102, and the bottom has a shell bottom 103. The shell cover 102 is provided with a first through hole 104, and the inner wall of the support shell 1 is provided for the telescopic support body to extend and retract. The telescopic groove 105 is provided. One end of the screw 2 extends into the receiving cavity 101 through the first through hole 104 and is screwed into the nut sleeve 3. The nut sleeve 3 has an internal threaded hole 106, and the outside of the screw 2 has an external thread. One end of the connecting rod 44 is hinged to the nut sleeve 3, and the other end is hinged to the telescopic support body. The knob 6 is fixedly connected to the upper end of the screw 2. By rotating the knob 6, the raising and lowering of the nut sleeve 3 can be controlled to control the opening and retraction of the telescopic support body. This includes two actions: one of which is to turn the knob 6 clockwise, thereby opening the nut sleeve 3 and the screw 2. During the first tightening action, with screw 2 rotating horizontally, nut sleeve 3 is forced to move upwards, simultaneously pulling the end of connecting rod 44 hinged to nut sleeve 3 upwards. This, in turn, pulls the end of connecting rod 44 hinged to telescopic support body, causing screw 2 to move horizontally. At this time, the angle between connecting rod 44 and nut sleeve 3 gradually decreases, and the telescopic support body retracts. The second action is to turn knob 6 counterclockwise, engaging nut sleeve 3 and screw 2 in the opposite loosening direction. With screw 2 rotating horizontally, nut sleeve 3 is forced to move downwards, simultaneously... The end of the push rod 44 that is hinged to the nut sleeve 3 moves downward, and the end of the push rod 44 that is hinged to the telescopic support moves outward of the telescopic groove 105. At this time, the angle between the push rod 44 and the nut sleeve 3 is gradually increased, and the telescopic support is pushed outward, thereby forming a tightening effect on the vehicle cup holder. It should be understood that the diameter of the support shell 1 is smaller than the diameter of the cup holder. Preferably, the support shell 1 is an inverted cone shape, so that its lower end can be inserted into the cup holder, and its upper end is flush with the upper end of the cup holder, which is convenient for aesthetics and stability.
[0044] Specifically, one end of the connecting arm 30A is fixedly connected to the cover 102 of the support shell 1 of the telescopic support fixing seat 10A, and the other end is connected to the small table 20A through the damping rotation mechanism 40A. Preferably, the damping rotation mechanism 40A can be in the form of a combination of bolts and washers to enable the small table 20A to rotate relative to the connecting arm 30A.
[0045] Specifically, the damping rotation mechanism 40A includes a damping washer assembly 7, a damping bolt central shaft 8, a damping nut 9, a locking damping seat 10, a locking branch pipe 11, an upper locking plate 12, and a lower locking plate 13. The lower end of the small table 20A is provided with a tabletop support 14, one end of which is a cylindrical end with a damping annular cavity 14a inside. The upper locking plate 12 has a first sleeve hole 121 inside, and the lower locking plate 13 has a second sleeve hole 121 inside. 31. The damping pad assembly 7 is provided with a third set of holes 701. The locking damping seat 10 includes a locking part 10a at the lower end and a damping head 10b at the upper end. The inner side of the damping head 10b is provided with a damping groove 10b1, which faces upward. The damping ring cavity 14a faces downward. The locking branch tube 11 is provided with a locking slot 11a that mates with the shaped hole of the locking part 10a. Preferably, both the locking slot 11a and the locking part 10a are quincunx-shaped, which can achieve the following: Figure 12 and Figure 13 As shown, the small tabletop 20A can be easily pulled out from the locking branch tube 11 (because the locking damping seat 10 and the locking branch tube 11 are not locked together). This facilitates transportation, storage, and quick installation, and also allows for the replacement of locking branch tubes 11 of different heights to accommodate people of different heights. The bottom of the locking branch tube 11 is fixedly connected to the connecting arm 30A. The upper locking plate 12 is locked to the tabletop support 14, and the lower locking plate 13 is locked to the locking damping seat 10. The damping bolt central shaft 8 passes sequentially from top to bottom through the first set hole 121 of the upper locking plate 12, the second set hole 131 of the lower locking plate 13, and the third set hole 701 of the damping pad group 7, and is locked by the damping nut 9 at the bottom. A part of the damping pad group 7 is located between the upper locking plate 12 and the lower locking plate 13, and a part is located between the damping nut 9 and the lower locking plate 13, thus forming a damping rotation mechanism 40A with a rotating shaft that forms damping around the damping pad group 7.
[0046] Specifically, the upper end face of the damping ring cavity 14a is provided with a first locking hole 14a1, the upper locking plate 12 is provided with a second locking hole 122 corresponding to the position of the first locking hole 14a1, the end face of the damping head 10b is provided with a third locking hole 10b2, and the lower locking plate 13 is provided with a fourth locking hole 132 corresponding to the position of the third locking hole 10b2. The upper locking plate 12 and the desktop support 14 are locked together through the first locking hole 14a1 and the second locking hole 122. The locking damping seat 10 and the lower locking plate 13 are locked together through the third locking hole 10b2 and the fourth locking hole 132. The upper locking plate 12, the lower locking plate 13, the damping bolt central shaft 8, the damping washer and the damping nut 9, and the damping head 10b of the locking damping seat 10 are all located inside the damping ring cavity 14a.
[0047] The damping pad assembly 7 includes a thick washer 71, an upper locking clip 72, a lower locking clip 73, and a buffer pad assembly 74. The thick washer 71 and the upper locking clip 72 are located between the upper locking plate 12 and the lower locking plate 13. The buffer pad assembly 74 is located between the lower locking plate 13 and the damping nut 9. The damping bolt central shaft 8 has a first anti-rotation tangential surface 801. The upper locking plate 12, the upper locking clip, and the lower locking clip are all provided with a second anti-rotation tangential surface 802 that cooperates with the first anti-rotation tangential surface 801 to prevent rotation.
[0048] The buffer pad group 74 is composed of several longitudinally stacked buffer pad groups 74, wherein each buffer pad 740 includes an upper conical groove surface 741, a lower conical groove surface 742, an upper annular fan surface 743 and a lower annular fan surface 744, wherein the upper annular fan surface 743 of the next buffer pad 740 and the lower annular fan surface 744 of the previous buffer pad 740 mutually cushion and compress each other.
[0049] It is important to understand that in this damping rotation mechanism 40A, the upper locking plate 12 is fixedly connected to the tabletop support 14, and the slot of the upper locking plate 12 has a second anti-rotation tangential surface 802, which cooperates with the first anti-rotation tangential surface 801 of the damping bolt central shaft 8. Therefore, when the small table 20A is rotated, the damping bolt central shaft 8 will also rotate. The slot of the lower locking plate 13, however, lacks the second anti-rotation tangential surface 802; it is a round hole. Therefore, the damping bolt central shaft 8 passes directly through this round hole (the second sleeve hole 131). Similarly, the third sleeve hole 701 of the buffer pad assembly 74 is also a round hole. The upper locking clip 72 and lower locking clip 73, located above and below the lower locking plate 13, also have the second anti-rotation tangential surface 802, and thus will also rotate. The thick washer 71, being a round hole, is not rotated along with the table. Here, the washers involved in damping and buffering are mainly the thick washer 71 located at the upper end of the lower locking plate 13 and the buffer pad group 74 located at the lower end of the lower locking plate 13. The upper locking clip 72 and the lower locking clip 73 are used to clamp the lower locking plate 13, allowing the lower locking plate 13 to also generate a certain amount of buffering. On the other hand, the upper locking clip 72 also acts as an upward clamping force on the thick washer 71, generating the first damping force. The lower locking clip 73 clamps the buffer pad group 74 downward together with the damping nut 9, generating the second damping force. Therefore, with this structure design, the rotation damping of the small table 20A is very stable and not easy to loosen. Its tightness can also be adjusted.
[0050] Specifically, the connecting arm 30A includes a first mounting groove 15 and a second mounting groove 16. The first mounting groove 15 has an upward-facing opening and rotates in a circular manner with the knob 6. In one embodiment, the inner diameter of the first mounting groove 15 is slightly smaller than the inner diameter of the knob 6. This allows the knob 6 to form a design that encloses the first mounting groove 15, and the inner and outer circular shapes provide a circumferential limiting effect for the rotation of the knob 6, making the knob 6 more stable during rotation. The cover 102 of the support shell 1 has a fifth locking hole 102a, and the groove surface of the first mounting groove 15 has a sixth locking hole 151. The first mounting groove 15 and the support shell 1 are fixed together by the fifth locking hole 102a and the sixth locking hole 151. The slot 16 is slotted downwards. The second assembly slot 16 has a seventh locking hole 161. The bottom of the locking branch tube 11 has an eighth locking hole 11b. The second assembly slot 16 and the locking branch tube 11 are fixed to each other through the seventh locking hole 161 and the eighth locking hole 11b. The locking part 10a of the locking damping seat 10 is provided with a first magnet 2a. The bottom of the locking slot 11a of the locking branch tube 11 is provided with a second magnet 2b. The first magnet 2a and the second magnet 2b attract each other magnetically when the locking part 10a is inserted into the locking slot 11a. During daily disassembly and assembly, the small table 20A and the telescopic support fixing seat 10A can be directly pulled out from the locking slot 11a through the locking part 10a, thereby disassembling the device into two sub-parts, which is also convenient for storage and transportation.
[0051] The nut sleeve 3 is provided with a plurality of longitudinally opened pivot grooves 31 arranged in an array along the outer circumference of the nut sleeve 3. The pivot grooves 31 are provided with a first hinge hole 311. The inner side of the telescopic support is provided with a second hinge hole 51. The two ends of the connecting rod 44 are respectively provided with a first rotating shaft 1a and a second rotating shaft 1b, wherein the first rotating shaft 1a is rotatably engaged with the first hinge hole 311, and the second rotating shaft 1b is rotatably engaged with the second hinge hole 51. Here, the two ends of the connecting rod 44 are respectively provided with holes for the first rotating shaft 1a and the second rotating shaft 1b to pass through.
[0052] The inner wall of the telescopic groove 105 is provided with a limiting guide rail 101a, and the outer side of the telescopic support body is provided with a limiting guide groove 52 corresponding to the limiting guide rail 101a. The top of the screw 2 is provided with a first limiting part 21 and the bottom is provided with a second limiting part 22 to limit the vertical travel of the nut sleeve 3 on the screw 2. In some cases, the second limiting part 22 can also be provided at the bottom 103 of the support shell 1, in the form of a seat groove. A drilled hole is provided in the seat groove for the shaft tip 24 at the bottom of the screw 2 to rotate. 3. Once it reaches this position, it can no longer go down. A guide rod 17 is provided between the cover 102 and the bottom 103 of the support shell 1. The guide rod 17 passes through the guide rod hole 171, thereby limiting the up and down sliding of the nut sleeve 3. The inner side of the knob 6 is provided with a socket 61. The socket 61 is provided with a first cross-section 611. The top of the screw 2 is provided with a plug-in part 23. The plug-in part 23 is provided with a second cross-section 231 that cooperates with and limits the first cross-section 611. The plug-in part 23 is inserted into the socket 61.
[0053] The desktop support 14 includes a connecting part 141 and a fixing part 142. The damping ring cavity 14a is located inside the connecting part 141. The fixing part 142 is a long strip-shaped fixing plate, and a fixing groove 142a is formed by a recess on the inner side of the fixing part 142. Several plate fixing holes 142b are provided on the top wall of the fixing groove 142a. Several pre-embedded threaded tubes 202 are provided on the lower end face of the small table 20A corresponding to the plate fixing holes 142b. The desktop fastener is fixedly connected to the small table 20A through the plate fixing holes 142b and the pre-embedded threaded tubes 202. The outer periphery of the small table 20A is also wrapped with a metal edging 203.
[0054] As described above, the small table 20A can rotate with damping relative to the connecting arm 30A, thus enabling the small table 20A to be used in both the driver's and passenger's directions. Simultaneously, the height of the locking branch tube 11 and the length of the connecting arm 30A are variable. Changing the height of the locking branch tube 11 allows the small table 20A to be used by people of different heights, and it can also be placed in application scenarios with different table heights or elevation differences. Similarly, changing the length of the connecting arm 30A allows it to extend to the rear seats, thus enabling the small table 20A to be used in the rear as well. However, in this mode, the telescopic support fixing seat 10A of the small table 20A is fixed in the cup holder in the front row, allowing for flexible configuration and use.
[0055] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
