Description

Technical Field

[0001] This invention belongs to the field of new energy vehicles, and in particular relates to a vehicle-mounted table. Background Technology

[0002] A car folding table is a small folding table designed for use inside a car, primarily to provide extra usable space for passengers to work, eat, or engage in other activities while driving. When folded, it is typically installed in the car's armrest. The traditional car folding table structure includes: a base, rotatable support legs connected to the upper end of the base, rotatable support arms mounted on the support legs, and a tabletop mounted on the support arms. The tabletop includes: a first panel and a second panel rotatably connected to the first panel via hinges; the first panel is fixed to the support arms. However, it has disadvantages: 1. The tabletop cannot be moved horizontally, limiting its use and failing to meet diverse user needs. Furthermore, while similar movable tabletops exist in other fields, they typically lack damping and positioning functions; direct application to car tables poses significant safety hazards. 2. The friction on the hinges cannot be adjusted as needed. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a vehicle-mounted table with translation function.

[0004] To solve the above problems, the technical solution adopted by the present invention includes: a base, a support leg rotatably connected to the upper end of the base, a support arm rotatably disposed on the support leg, and a tabletop disposed on the support arm. The tabletop includes a first plate body and a second plate body rotatably connected to the first plate body via a hinge. The bottom of the first plate body is provided with a sliding groove, and the bottom of the sliding groove is provided with a positioning plate. The positioning plate is provided with a first starting positioning hole and a first ending positioning hole. The support arm is provided with a slider that slides and engages with the sliding groove. The slider is provided with a positioning bead that engages with the first starting positioning hole and the first ending positioning hole, and slide rails are provided on both sides. The lower end of the positioning bead is provided with a spring.

[0005] The two ends of the chute are provided with first buffer pads.

[0006] The slide is provided with a second starting positioning hole and a second ending positioning hole at both ends, which are positioned in conjunction with the damping protrusion.

[0007] The hinge includes a hinge base and hinges rotatably connected to both ends of the hinge base via a rotating shaft. A set of friction pads that frictionally engage with the rotating shaft are provided. The friction pads have an opening at the upper end and a positioning protrusion at the lower end. The hinge base has friction pad mounting cavities at both ends that are adapted to the friction pads, and the friction pad mounting cavities have positioning grooves that positionally engage with the positioning protrusions.

[0008] The friction pad has two symmetrical ends, which are narrower at the top and wider at the bottom, and the bottom of the end face is provided with a clearance groove.

[0009] There are gaps between the friction pad and the friction pad mounting cavity, as well as between the positioning protrusion and the positioning groove.

[0010] The inner wall of the hinge is provided with a buffer pad mounting cavity, and a second buffer pad that buffers with the hinge seat is provided in the buffer pad mounting cavity.

Detailed Implementation

[0017] Reference Figures 1-10 As shown, the vehicle-mounted table with translation function of the present invention includes a base 1, a support leg 2 rotatably connected to the upper end of the base 1, a support arm 3 rotatably disposed on the support leg 2, and a table 4 disposed on the support arm 3. The table 4 includes a first plate 5 and a second plate 7 rotatably connected to the first plate 5 via a hinge 6. The bottom of the first plate 5 is provided with a sliding groove 8, and the bottom of the sliding groove 8 is provided with a positioning plate 9. The positioning plate 9 is provided with a first starting positioning hole 10 and a first ending positioning hole 11. The support arm 3 is provided with a slider 12 that slides and engages with the sliding groove 8. The slider 12 is typically connected to the support arm 3 by screws. The slider 12 is provided with a positioning bead 13 that positions and engages with the first starting positioning hole 10 and the first ending positioning hole 11, and the slider 12 is provided with slide rails 14 on both sides. The lower end of the positioning bead 13 is provided with a spring 18. For ease of assembly, a push rod 39 is provided at the lower end of the positioning bead 13. The push rod 39 is placed in the push rod groove 40 of the support arm 3, and the spring 18 is placed at the rear end of the push rod 39 to ensure stability. The slide rail 14 is provided with damping spring pieces 15 at both ends, and the damping spring pieces 15 are provided with damping protrusions 16 that abut against the inner wall of the slide groove 8. Through the friction between the damping protrusions 16 and the inner wall of the slide groove 8, the slider 12 has a damping effect during the sliding process.

[0018] Preferably, the two ends of the slide groove 8 are provided with first buffer pads 20 to buffer the slider 12 after it slides into place.

[0019] Preferably, the slide groove 8 has a second starting positioning hole 21 and a second ending positioning hole 22 at both ends that engage with the damping protrusion 16. When the slider 12 and the table 4 are in the starting position, the damping protrusion 16 is positioned in the second starting positioning hole 21. When the slider 12 and the table 4 slide to the ending position, the damping protrusion 16 is positioned in the second ending positioning hole 22. This further improves the stability of the positioning.

[0020] Preferably, the hinge 6 includes a hinge base 23 and hinges 25 rotatably connected to both ends of the hinge base 23 via a rotating shaft 24. A set of friction pads 26 are provided on the rotating shaft 24 for frictional engagement. The friction pads 26 have an opening 27 at the upper end and a positioning protrusion 28 at the lower end. The hinge base 23 has friction pad mounting cavities 29 at both ends that are adapted to the friction pads 2), and the friction pad mounting cavities 29 have positioning grooves 30 that are positioned and engaged with the positioning protrusions 28.

[0021] Preferably, the two end faces 31 of the friction pad 26 are symmetrical and narrower at the top and wider at the bottom to ensure uniform force distribution and improve strength. The bottom of the end face 31 is provided with a relief groove 17, into which lubricating grease can enter, so that the surface of the rotating shaft 2 is covered with grease, thereby making the force value smooth and durable when it rotates.

[0022] Preferably, gaps 32 exist between the friction pad 26 and the friction pad mounting cavity 29, as well as between the positioning protrusion 28 and the positioning groove 30. These gaps 32 are filled with lubricating grease. The presence of these gaps 32 results in very low resistance at the initial opening position of the hinge 25, facilitating the opening of the tabletop and also facilitating the storage of lubricating grease.

[0023] Preferably, the inner wall of the hinge 25 is provided with a buffer pad mounting cavity 33, and a second buffer pad 34 is provided in the buffer pad mounting cavity 33 to buffer against the hinge seat 23, so as to avoid noise generation when the hinge 25 is closed.

[0024] Preferably, one end of the rotating shaft 24 is provided with a riveting tooth 35, which is riveted and fixed to the shaft hole 36 on the hinge 25 by means of the riveting tooth 35, so as to improve the strength after assembly.

[0025] Preferably, the hinge 25 has screw holes 37 at both ends, and a positioning post 38 is provided between the screw holes 37. The positioning post 38 is positioned and engaged with the positioning groove on the table, thereby facilitating the alignment of the screw holes 37 and improving the connection strength.

Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed structure and technical content to create equivalent embodiments without departing from the scope of the present invention.
