Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, and in particular to an automobile seat table plate structure with a leveling function. Background Art

[0002] With the rapid development of the automobile industry, cars are becoming more and more popular in people's lives and have become an indispensable part of most people's lives. In people's work and life, cars not only serve as a means of transportation for commuting to and from get off work, but can also become the main choice of transportation for leisure travel.

[0003] During a long ride, it is inevitable that you will need to eat or drink. In general, you can only put food or drinks on the seats, or even hold them in your hands. Putting them on the seats will not only make the car messy, but if the food has been opened, it will also dirty the seats or contaminate the food itself. Holding them in your hands will also cause inconvenience when eating. Therefore, some car seats (front seats) are equipped with foldable table boards behind them.

[0004] After the car seat table is installed or used for a long time, the parts connecting the table and the seat are prone to loosening or deformation, causing the table to tilt when in use, affecting the user experience. Summary of the invention

[0005] The utility model aims to provide a car seat table structure with a leveling function.

[0006] To achieve the above-mentioned purpose, the technical solution provided by the utility model is: a car seat table structure with a leveling function, including a table, a folding structure respectively hinged between the table and the rear of the car seat, the folding structure including a pair of upper connecting rods and a pair of lower connecting rods, the upper connecting rod and the lower connecting rod are respectively hinged on the upper side and the lower side of the hinge at the rear of the car seat, the upper connecting rod and the lower connecting rod are respectively hinged on the front side and the rear side of the hinge at the table, the lower connecting rod is formed with a bending portion that is close to the upper connecting rod when the folding structure is unfolded, the upper connecting rod is provided with a table leveling device for adjusting the distance between the bending portion and the upper connecting rod, and the horizontal angle of the table is adjusted by the table leveling device.

[0007] Preferably, the table top leveling device includes a through hole formed in the upper connecting rod, a long-axis screw threaded in the through hole, and a nut formed at the end of the long-axis screw. After passing through the through hole, the long-axis screw resists on the bent portion of the lower connecting rod, so that the distance between the bent portions of the upper connecting rod and the lower connecting rod changes, thereby changing the horizontal angle of the table top.

[0008] Furthermore, a plurality of pits are densely formed on the upper surface of the bending portion, and the forming direction of the pits is perpendicular to the moving direction of the lower connecting rod.

[0009] Preferably, a spirit level is provided on the table top.

[0010] The technical effect of the present application is embodied in: by adjusting the distance between the bending parts of the upper connecting rod and the lower connecting rod through the table top leveling device, the horizontal angle of the table top is adjusted to keep the table top in a horizontal state for use.

[0017] The present invention will be further described below in conjunction with specific embodiments: Example

[0018] like Figure 1-6 The utility model is shown as a car seat table structure with a leveling function, including a table, a folding structure 3 respectively hinged between the table 1 and the rear of the car seat 2, the folding structure 3 including a pair of upper connecting rods 31 and a pair of lower connecting rods 32, the upper connecting rod 31 and the lower connecting rod 32 are respectively hinged to the upper side and the lower side of the hinge at the rear of the car seat 2, the upper connecting rod 31 and the lower connecting rod 32 are respectively hinged to the front side and the rear side of the hinge of the table 1, the lower connecting rod 32 is formed with a bending portion 321 which is close to the upper connecting rod 31 when the folding structure 3 is unfolded, the upper connecting rod 31 is provided with a table leveling device 4 for adjusting the distance between the bending portion 321 and the upper connecting rod 31, and the horizontal angle of the table 1 is adjusted by the table leveling device 4.

[0019] Among them, the table top leveling device 4 includes a through hole formed in the upper connecting rod 31, a long-axis screw 41 screwed in the through hole and a nut 42 formed at the end of the long-axis screw 41. After passing through the through hole, the long-axis screw 41 resists on the bending portion 321 of the lower connecting rod 32. The length of the long-axis screw 41 is long enough to change the distance between the bending portion 321 of the upper connecting rod 31 and the lower connecting rod 32 to change the horizontal angle of the table top 1.

[0020] In order to make the long-axis screw 41 of the table top leveling device 4 more stable when resisting at the bending portion 321, a plurality of grooves 322 are densely formed on the upper surface of the bending portion 321, and the forming direction of the grooves 322 is perpendicular to the movement direction of the lower connecting rod 32. When the long-axis screw 41 resists at the bending portion 321, it conflicts with the grooves 322 and is not easy to slip off.

[0021] A spirit level 5 is provided on the table top 2 . The spirit level 5 is embedded in the table top 1 or embedded in the side of the table top 1 . The table top leveling device 4 is adjusted by observing the spirit level 5 .

[0022] Working principle:

[0023] By adjusting the table top leveling device 4, that is, adjusting the distance between the upper connecting rod 31 and the bent portion 321 of the lower connecting rod 32, the horizontal angle of the table top 1 is changed.

[0024] When the distance between the upper connecting rod 31 and the bent portion 321 of the lower connecting rod 32 decreases, the outer side of the table top 1 rotates downward; when the distance between the upper connecting rod 31 and the bent portion 321 of the lower connecting rod 32 increases, the outer side of the table top rotates upward.

[0025] The horizontal state can be adjusted by adjusting the angle of the outer side of the table top 1.
