[0030] Embodiment 1

[0031] like Figure 1-4 As shown, a table support for a seat provided in this embodiment includes a support plate 1, a swing arm 2 and an adjustment variable mechanism 3, the swing arm 2 is hinged to one side of the support plate 1, the adjustment part of the adjustment variable mechanism 3 is installed on the support plate 1, the action end 34 of the adjustment variable mechanism 3 is located on one side of the swing arm 2, when the adjustment part is adjusted, different positions of the action end 34 abut against the swing arm 2, and are used to fix the angle between the swing arm 2 and the support plate 1, and also includes a mounting plate 4 for mounting on the seat, and the other end of the swing arm 2 is hinged to the mounting plate 4. Specifically, the swing arm 2 is composed of a first connecting rod 21 and a second connecting rod 22, one end of the first connecting rod 21 and the second connecting rod 22 is respectively hinged to one side of the support plate 1, and the other end of the first connecting rod 21 and the second connecting rod 22 is respectively hinged to one side of the mounting plate, thereby forming an integral structure in which the swing arm 2 is respectively hinged to the support plate 1 and the mounting plate 4. The technical solution of this embodiment introduces an adjustment variable mechanism, which allows the user to independently adjust the table plane by adjusting the variable mechanism without being restricted by the inclination angle of the seat. Specifically, when the seat is tilted and the tabletop plane is no longer horizontal, the user can adjust the adjustment part so that different positions of the action end and the swing arm are offset. Different positions of the action end can change the angle between the swing arm and the support plate, thereby adjusting the tilt angle of the tabletop plane. The user can adjust according to actual needs until the surface of the tabletop returns to a horizontal state. Therefore, this technical solution realizes the independent adjustment of the tabletop plane after the seat is tilted through an innovative combination of the support plate, the swing arm and the adjustment variable mechanism, effectively solving the problem in the prior art that the tabletop plane cannot be independently adjusted to a horizontal state. This design not only improves the comfort and convenience of the seat, but also provides new ideas and methods for the design of seat accessories.

[0032] There are many methods for adjusting the level-changing mechanism. In this embodiment, specifically, the level-changing mechanism 3 includes an adjusting wheel 31, a transmission rod 32 and a level-changing member 33. The action end 34 is located on the level-changing member 33. The adjusting wheel 31 is movably connected and installed on the support plate 1 as an adjusting part. The level-changing member 33 is located on one side of the swing arm 2. The two ends of the transmission rod 32 are respectively hinged with the adjusting wheel 31 and the level-changing member 33. One end of the level-changing member 33 is clamped on the support plate 1. When the adjusting wheel 31 is rotated, the level-changing member 33 moves in a straight line direction, and different positions of the action end 34 are against the swing arm 2, which is used to fix the angle between the swing arm 2 and the support plate 1. This combined structure is more convenient and accurate in operation. The adjusting wheel is movably connected to the support plate as an adjusting part. The user can drive the transmission rod by simply rotating the adjusting wheel, thereby causing the level-changing member to move in a straight line direction, so that different positions of the action end are against the swing arm in the straight line direction. Since it is a linear movement, the contact state between the action end and the swing arm is clearer, so it is easier to design the required adjustment effect. In addition, since the two ends of the transmission rod are respectively hinged with the adjustment wheel and the step-changing member, this design makes the force transmission smoother, reduces energy loss, and also enhances the durability of the mechanism. Therefore, the design of this adjustment and step-changing mechanism not only improves the adjustment accuracy of the table support, but also enhances its stability and service life, making it a further preferred solution.

[0033] Preferably, the support plate 1 is provided with a side plate 11, and a through hole 111 is provided on the side plate 11, and the active end 34 of the step-changing member 33 passes through the through hole 111 and is located on one side of the swing arm 2. In the design of the table support, the side plate provided on the support plate and the through hole provided on the side plate are another preferred solution. The design of the side plate increases the strength of the support plate, making the entire support more stable. At the same time, the through hole provided on the side plate allows the active end of the step-changing member to pass through, and this design makes the linear motion of the step-changing member smoother and can ensure that the contact between the active end and the swing arm is more precise.

[0034] Preferably, a gear-shaped dial portion 311 is provided on the outer side of the adjustment wheel 31. The gear-shaped dial portion increases the friction between the adjustment wheel and the finger, so that the user can feel obvious resistance feedback when adjusting, thereby having a better feel and easier to control the adjustment force.

[0035] Preferably, the support plate 1 is further provided with a top column 12 on one side of the adjusting wheel 31. The top column plays a role in preventing the adjusting wheel from rotating in other directions, and can better prevent the adjusting wheel from rotating excessively. In order to better increase the contact area of ​​the dial portion 311, a groove 312 is provided on the inner side of the adjusting wheel 31, and when the adjusting wheel is about to rotate excessively, the top column 12 and the groove 312 are abutted.

[0036] Preferably, two swing arms 2 are provided, and the swing arms 2 are respectively located at both ends of the support plate 1 and are respectively hinged to both sides of the support plate 1, and two action ends 34 of the adjustment and variable mechanism 3 are provided, and are respectively located on one side of the two swing arms 2. The design of the double swing arms can more evenly disperse the pressure on the table board, and enhance the overall stability and load-bearing capacity of the table board bracket. At the same time, the two swing arms are respectively hinged to both sides of the support plate, so that the table board can maintain a more balanced and stable state when adjusting the angle. The introduction of the double adjustment variable mechanism further improves the adjustment accuracy and flexibility of the table board bracket. By adjusting the action end positions of the two adjustment variable mechanisms respectively, the angle between the two swing arms and the support plate can be more accurately controlled, thereby achieving accurate adjustment of the table board angle. This design not only improves the comfort of the table board, but also meets the needs and preferences of different users. In addition, the design of the double swing arms and the double adjustment variable mechanism also enhances the durability and reliability of the table board bracket. Due to the more uniform force and more precise adjustment, the table board bracket is not prone to loosening or deformation during long-term use, thereby extending its service life.

[0037] Preferably, the action end 34 is a stepped structure. The action end is designed as a stepped structure, which means that the adjustment variable mechanism can achieve multiple selectable precise contact points with the swing arm when adjusting the angle of the table top. This design enables the table top bracket to achieve better results during the adjustment process, thereby ensuring that the table top can be adjusted to different angles, thereby maintaining a stable support state. The action end of the stepped structure can also form multiple support points when it is against the swing arm, and these support points work together to significantly enhance the load-bearing capacity of the table top bracket. This means that users can place heavier items on the table top without worrying about the stability and safety of the bracket. In this embodiment, the action end is provided with a three-layer stepped structure, which can meet the current usage requirements.

In order to facilitate user adjustment, the adjustment part of the adjustment variable mechanism is suitable to be exposed outside the shell.
