Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] like Figures 1 to 9 As shown, this embodiment provides a vehicle seat table, including: a column 1 installed on the rear side of the car seat, and a table 2 slidably installed along the length of the column 1; the upper end of the column 1 is installed on the top of the car seat through a snap-fit ​​structure, and the lower end of the column 1 is installed on the bottom of the car seat through a clamping mechanism; vertical limiting grooves 11 are symmetrically opened on both sides of the column 1 along its length, and upper sliders 31 and lower sliders 32 are slidably installed in the vertical limiting grooves 11 from top to bottom respectively; one side of the table 2 is rotatably installed with the two upper sliders 31, and an inclined rotating rod 321 is rotatably installed on the lower side of the lower slider 32, with the top of the inclined rotating rod 321 hinged to the lower part of the table 2. In this embodiment, the upper slider 31 and the lower slider 32 are slidably installed from top to bottom in the vertical limiting groove 11 and fastened by the first knob screw 312 and the second knob screw 322 respectively, so as to realize the convenient adjustment of the height of the table board 2. At the same time, the tilting rod 321 is rotatably installed on the lower side of the lower slider 32. The top of the tilting rod 321 is hinged to the lower part of the table board 2. By adjusting the height of the lower slider 32, the tilt angle of the table board 2 can be conveniently adjusted, which is convenient and practical.

[0028] Furthermore, a limiting slot 21 is opened on one side of the tabletop 2 to form two symmetrical side protrusions 22; the column 1 is slidably installed in the limiting slot 21; an L-shaped adapter block 311 is rotatably installed on the upper side of the upper slider 31, the vertical block of the L-shaped adapter block 311 is rotatably installed on the upper side of the upper slider 31, and the horizontal block of the L-shaped adapter block 311 is fixedly installed on the lower bottom surface of the side protrusions 22; thus enabling the tabletop 2 to rotate relative to the upper slider 31 for easy adjustment.

[0029] Furthermore, the upper slider 31 is fastened to the vertical limiting groove 11 by the first knob screw 312, and the lower slider 32 is fastened to the vertical limiting groove 11 by the second knob screw 322; this facilitates the sliding adjustment of the upper slider 31 and the lower slider 32 in terms of height.

[0030] For further details, please refer to Figure 1 and Figure 3 The snap-fit ​​structure includes an upper connecting plate 41 rotatably mounted on the rear side of the top of the column 1, an upper crossbar 42 rotatably mounted on the end of the upper connecting plate 41, and arc-shaped hooks 43 rotatably mounted on both ends of the upper crossbar 42. Two vertical support rods are fixedly mounted on the top of the car seat, and a seat headrest is fixedly mounted on the top of the vertical support rods. The arc-shaped hooks 43 snap onto the outside of the vertical support rods, facilitating the fixed installation of the top of the column 1. Furthermore, rotating blocks 421 are rotatably mounted on both ends of the upper crossbar 42, and a third knob screw 44 is threaded to one end of the arc-shaped hook 43. The third knob screw 44 passes through a through hole on the lower side of the rotating block 421. The side of the rotating block 421 has an arc-shaped groove 4211 that mates with the side of the vertical support rod. When the third knob screw 44 is rotated forward, the arc-shaped hooks 43 approach the rotating block 421 and clamp the vertical support rods. This achieves the clamping of the vertical support rods at the top of the car seat by the arc-shaped hooks 43, while also facilitating disassembly.

[0031] For further details, please refer to Figures 4 to 6 As shown, the clamping mechanism includes a lower connecting plate 51 rotatably mounted on the rear side of the bottom of the column 1, a telescopic rod assembly rotatably mounted on the end of the lower connecting plate 51, and clamping plates 52 mounted on both ends of the telescopic rod assembly; clamping plates 52 are fixedly mounted on one end of the telescopic rod assembly, and a short rod 53 is fixedly mounted on the other end. The short rod 53 is slidably mounted in a sliding hole opened on the side of the clamping plate 52, and a knob 531 is threadedly connected to the end of the short rod 53; the knob 531 rotates to drive the clamping plate 52 to clamp the car seat; in use, the two clamping plates 52 are located on both sides of the lower part of the car seat, and rotating the knob 531 drives the clamping plates 52 to clamp the car seat, thus realizing that the bottom of the column 1 is fixedly mounted on the lower part of the car seat.

[0032] Furthermore, the telescopic rod assembly includes an outer tube 54 and an inner rod 55. One end of the inner rod 55 is slidably installed inside the outer tube 54, and the other end is fixedly installed with a short rod 53. An inner locking assembly is fixedly installed at one end of the short rod 53. The inner locking assembly includes an eccentric shaft 61 fixedly installed at the end of the short rod 53 and a chamfered ring 62 sleeved on the outside of the eccentric shaft 61. An annular groove is coaxially formed on the outside of the eccentric shaft 61. A drive protrusion 611 is integrally installed on the bottom surface of the annular groove. The chamfered ring 62 is installed in the annular groove. An arc-shaped slot 621 is formed at one end of the chamfered ring 62, and the drive protrusion 611 is installed in the arc-shaped slot 621. When the inner rod 55 rotates, it drives the drive protrusion 611 on the eccentric shaft 61 to rotate, thereby driving the chamfered ring 62 to rotate, so that the outer side of the chamfered ring 62 is either pressed against or released from the inner wall of the outer tube 54. In use, when a stable connection between the outer tube 54 and the inner rod 55 is required, the inner rod 55 is rotated to gradually drive the eccentric shaft 61 and the driving protrusion 611 to rotate synchronously, thereby driving the outer side of the segmental retaining ring 62 to fit tightly against the inner wall of the outer tube 54; when the outer tube 54 and the inner rod 55 need to be separated, the inner rod 55 is rotated in the opposite direction to gradually drive the eccentric shaft 61 and the driving protrusion 611 to rotate synchronously, thereby driving the outer side of the segmental retaining ring 62 to separate from the inner wall of the outer tube 54.

[0033] For further details, please refer to Figure 4 and Figure 5 A U-shaped horizontal block 12 is fixedly installed at the bottom of the column 1. A hinge shaft is fixedly installed at one end of the lower connecting plate 51. The two ends of the hinge shaft are rotatably installed between the two side blocks of the U-shaped horizontal block 12. The end of the hinge shaft extending out of the side block of the U-shaped horizontal block 12 is threadedly connected to a fourth knob screw 511. When the fourth knob screw 511 is rotated, the lower connecting plate 51 is pressed tightly against the inner side of the side block of the U-shaped horizontal block 12. A washer annular groove coaxial with the hinge shaft is opened on the side of one end of the lower connecting plate 51. An annular washer 512 is installed in the washer annular groove. Several fan-shaped protrusions are evenly distributed on the side of the annular washer 512. The fan-shaped protrusions increase the friction and ensure a more stable and tight fit between the lower connecting plate 51 and the inner side of the side block of the U-shaped horizontal block 12.
