Description

Technical Field

[0001] This utility model relates to the field of tabletop bracket technology, and in particular to a hardware bracket for automobile tabletops. Background Technology

[0002] Car tray tables, a common and convenient component in vehicles, are primarily installed on the back of the front seats, providing a support platform for rear passengers to eat, work, or place items while traveling. To adapt to the spatial layout requirements of vehicles, current car tray tables generally adopt a foldable structure design, which can be folded away for storage when not in use, effectively saving space inside the vehicle, and therefore are widely used in various passenger cars.

[0003] However, most existing car seats are equipped with tilt adjustment to meet the comfort needs of passengers in different sitting positions. When the seat is tilted, the tabletop fixed to the back of the seat tilts synchronously with the seat, causing the supporting surface of the tabletop to not remain level. This problem has a significant impact on usage scenarios that require a stable supporting surface, such as dining, writing, and operating a laptop: the tilted tabletop is prone to causing items placed on it to slip or tip over, which not only reduces the convenience of use but may also cause damage to items or safety hazards; at the same time, the non-level supporting surface also increases the difficulty of operation for users, seriously affecting the user experience and operational stability.

The first connecting shaft 13 is used to install the first connecting rod 14, and the second connecting shaft 17 is used to install the second connecting rod 18. The cooperation of the first connecting rod 14 and the second connecting rod 18 is used to connect the second fixing bracket 12 and the mounting bracket 1, and the first fixing bracket 11 and the mounting bracket 1, respectively. The second connecting rod 18 is used to drive the locking block 2. The second lever block 26 is used to restrict the first lever block 23, and the first lever block 23 is used to restrict the locking block 2, thereby locking the second connecting rod 18. The first connecting rod 14 is hinged to... A first screw 15 is provided, with a connecting block 16 threadedly connected to one end of the first screw 15. The connecting block 16 is fixedly connected to the mounting bracket 1. The first screw 15 is used to achieve the hinge between the first connecting rod 14 and the mounting bracket 1, and the connecting block 16 is used to connect the first screw 15 and the mounting bracket 1. A clearance groove 19 is provided on the mounting bracket 1 at the position corresponding to the locking block 2, and one end of the first lever block 23 is set in the clearance groove 19. The clearance groove 19 is used to avoid the locking block 2 and the first lever block 23.

The third screw 25 is used to realize the hinge between the first lever block 23 and the mounting bracket 1. A fourth screw 28 is hinged to the second lever block 26 and is fixedly connected to the mounting bracket 1. The fourth screw 28 is used to realize the hinge between the second lever block 26 and the mounting bracket 1. A first torsion spring 29 is sleeved on the fourth screw 28. One end of the first torsion spring 29 is disposed on the mounting bracket 1, and the other end is disposed on the second lever block 26. The first torsion spring 29 is used to provide a return spring force for the second lever block 26.A second torsion spring 210 is fitted onto the fourth screw 28, with one end of the second torsion spring 210 attached to the mounting bracket 1 and the other end attached to the first lever block 23. The second torsion spring 210 provides a return force to the first lever block 23.

The nuts 211 are used to lock the fourth screw 28, the third screw 25, and the second screw 22 onto the mounting bracket 1.

[0025] Working principle: When using this utility model, the first fixing bracket 11 and the second fixing bracket 12 are installed on the seat, and the table is installed through the mounting bracket 1. When the seat angle changes, the angle of the table can be adjusted to restore the table to a horizontal position. Specifically, pressing one end of the second lever block 26 causes the second lever block 26 to deflect on the fourth screw 28, deforming the first torsion spring 29. The groove 27 at the other end of the second lever block 26 no longer restricts the first lever block 23. With the cooperation of the two sets of first connecting rods 14 and second connecting rods 18, the angle of the mounting bracket 1 is adjusted. During this process, the second connecting rod 18 drives the locking block 2 to deflect on the second screw 22. The first tooth 21 engages with the second tooth 24, and the locking block 2 drives the first lever block 23 to deflect. After the mounting bracket 1 completes the angle adjustment, the second lever block 26 is released, and the first torsion spring 29... Under the action, the second lever block 26 resets and restricts the first lever block 23 again through the stepped groove 27, so that the locking block 2 cannot rotate, thereby locking the second connecting rod 18 and fixing the angle of the mounting bracket 1. Among them, the first connecting shaft 13 is used to install the first connecting rod 14, the second connecting shaft 17 is used to install the second connecting rod 18, the first screw 15 is used to realize the hinge between the first connecting rod 14 and the mounting bracket 1, the connecting block 16 is used to connect the first screw 15 and the mounting bracket 1, the clearance groove 19 is used to avoid the locking block 2 and the first lever block 23, the third screw 25 is used to realize the hinge between the first lever block 23 and the mounting bracket 1, the second torsion spring 210 is used to provide the reset elastic force for the first lever block 23, and the nut 211 is used to lock the fourth screw 28, the third screw 25 and the second screw 22 on the mounting bracket 1.
