DETAILED DESCRIPTION Example 1
[0017] Reference Figure 1-Figure 12 As shown, the slow-drop type vehicle-mounted folding table top of the present invention comprises a mounting seat 1, support legs 2 hinged on both sides of the mounting seat 1, two cross beams 3 hinged to the upper ends of the support legs 2, and a table top 4 hinged on the cross beams 3. The support legs 2 are hinged to the support legs 2 through a slow-drop type hinge a. The slow-drop type hinge a comprises: a rotating shaft 5, an inner plate 6, a torsion spring seat 7, an outer plate 8 and a disc spring 9. The rotating shaft 5 is connected to the upper end of the mounting seat 1 through a middle fixing seat 10 and is fixed by a screw 44.
[0018] The rotating shaft 5 is provided with an external thread 11 and an internal thread 12 at both ends, and a nut 13 is connected through the external thread 11, and a screw 15 is connected through the internal thread 12. The support leg 2 is rotatably arranged on both sides of the mounting seat 1 through the rotating shaft 5. The inner plate 6 is arranged on the outer side of the support leg 2 through the rotating shaft 5, and is fixed by the nut 13 on the rotating shaft 5. The lower end of the inner plate 6 is fixed to the mounting seat 1, and a damping gear 14 is arranged in the middle of the inner plate 6. The damping gear 14 has a damping function and can provide a damping effect during movement, which is a well-known technology. The torsion spring seat 7 is connected to the side of the inner plate 6 and is fixed by the screw 15 at the end of the rotating shaft 5. The outer end of the torsion spring seat 7 is provided with a torsion spring 16. The outer plate 8 is rotatably arranged on the torsion spring seat 7, and the inner wall of the outer plate 8 is provided with a speed change gear 17 engaged with the damping gear 14. A linkage plate 18 is provided between the outer plates 8 and is fitted to the support leg 2. A lever portion 19 is extended downward from the lower end of the support leg 2 and is fitted to the linkage plate 18. The outer plate 8 is driven to reset in the direction of the car armrest box by the torsion spring 16. When the support leg 2 is rotated in the unfolding direction, the support leg 2 drives the linkage plate 18 and the outer plate 8 to rotate synchronously, so that the speed gear 17 drives the damping gear 14 to rotate, thereby providing a damping effect during movement; when the support leg 2 is rotated in the folding direction, the linkage plate 18 and the outer plate 8 are driven to rotate synchronously by the lever portion 19, so that the speed gear 17 drives the damping gear 14 to rotate, thereby providing a damping effect during movement. In addition, since the support leg 2 is much longer than the lever portion 19, it is easier for the user to unfold the support leg 2, and when folding, it can be folded slowly and automatically. After being stacked, the disc spring 9 is arranged between the mounting seat 1 and the support leg 2 and between the support leg 2 and the inner plate 6 through the rotating shaft 5. The disc spring 9 compensates for the gap caused by the looseness of the nut 13 and the screw 15 through its stored energy to ensure the tightness and stability of the connection. At the same time, the disc spring can also compensate for the thermal expansion or wear of mechanical parts caused by temperature changes to maintain the stable operation of the system. A first spring locating pin 20 is provided at the upper end of the mounting seat 1, and first locating holes 21 are provided at both ends of the bottom of the support leg 2. The structure of the spring locating pin includes a shell and a spring and a pin body arranged in the shell. When the support leg 2 is in a vertical state (expanded state) or folded, the first spring locating pin 20 is positioned and matched with the first locating hole 21 to achieve the positioning of the table top. This is to prevent the abnormal folding or unfolding of the table top due to the bumps or sudden braking of the car.
[0019] Preferably, the bottom of the cross beam 3 is hinged with a side beam 22, the lower end of the side beam 22 is slidably connected to the slide groove 24 at the upper end of the support leg 2 through a roller 23, rolling wheels 25 are provided at both ends of the roller 23, and a rubber buffer pad 26 cooperating with the roller 23 is provided at the bottom of the slide groove 24, a second spring positioning pin 27 is provided at the upper end of the side beam 22, and a second positioning hole 28 is provided at the bottom of the cross beam 3. When the cross beam 3 is folded, the second spring positioning pin 27 is positioned in the second positioning hole 28 to prevent the cross beam 3 and the table top 4 from being accidentally opened. The side beam 22 is used to improve the support strength of the cross beam 3. At the same time, by providing the roller 23 and the rolling wheel 25, the sliding of the side beam 22 is more stable, and after sliding into place, the cooperation with the rubber buffer pad 26 makes it have a buffering effect.
[0020] Preferably, bushings 29 are provided on both sides of the support leg 2, and flanges 30 embedded in the bushings 29 are provided on the mounting seat 1 and the inner side plate 6 to improve the stability of the support leg 2 during rotation and support.
[0021] Preferably, a rubber buffer strip 31 is provided at the upper end of the linkage plate 18, a group of positioning grilles 32 are provided at the lower end of the linkage plate 18, and a first positioning groove 33 matching with the positioning grilles 32 is provided on the mounting seat 1. When the support leg 2 is opened, the linkage plate 18 collides with the support leg 2 through the rubber buffer strip 31 to reduce the sound, and at the same time, the positioning grilles 32 and the first positioning grooves 33 are used to position the support leg 2 to improve the stability of the support leg 2 when supporting. Preferably, a curved guard plate 34 is provided on one side of the support leg 2, and when the support leg 2 is folded, the curved guard plate 34 wraps around the mounting seat 1 and the inner plate 6 to play a protective role.
[0022] Preferably, a positioning edge 35 is provided at the bottom of the lever portion 19, and a second positioning groove 36 is provided on the inner side plate 6 to cooperate with the positioning edge 35. When the support leg 2 is fully opened, the positioning edge 35 is positioned and cooperated with the second positioning groove 36 to improve the stability of the support leg 2 when supporting.
[0023] Preferably, the torsion spring seat 7 is connected to the positioning rib 38 on the inner side plate 6 through the third positioning grooves 37 arranged on the inner end circumference, and the outer side of the torsion spring seat 7 is provided with a clamping groove 39 connected to the force arm of the torsion spring seat 7. Through the above structure, the installation angle of the torsion spring seat 7 can be adjusted, and the torsion force of the torsion spring seat 7 can be adjusted by adjusting the angle of the torsion spring seat 7, thereby adjusting the slow-down speed.
[0024] Preferably, the linkage plate 18 is provided with a panel 40, and a groove 41 is provided on the surface of the panel 40. After folding, the panel will cover the top of the mounting seat of the table board, so that the position has a storage function and good aesthetics. Preferably, a handle 42 is provided on one side of the cross beam 3. The user opens the support leg 2 and the cross beam 3 by pulling the handle 42 for easy operation. Example 2
