[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0044] like Figure 1-4 As shown, the present invention provides a self-balancing table top, which mainly includes: a frame mounting plate 110, a frame 120, a connecting rod mechanism 130, a table top assembly 140, a driving mechanism 150 and a circuit board 160.

[0045] The frame mounting plate 110 is fixedly mounted on a table support (such as a seat back). Two frames 120 are spaced apart and parallel to each other and bolted to each end of the frame mounting plate 110. Two linkage mechanisms 130 are provided, one corresponding to each frame 120. The table assembly 140 has an internal storage cavity. The drive mechanism 150 is fixedly mounted in the storage cavity of the table assembly 140 and located between the two linkage mechanisms 130.

[0046] The linkage mechanism 130 includes an active rod 131 and a driven rod 132. One end of the active rod 131 is rotatably connected to one end of the frame 120. The other end of the active rod 131 extends into the receiving cavity of the tabletop assembly 140 and is connected to the output end of the drive mechanism 150. One end of the driven rod 132 is rotatably connected to the other end of the frame 120. The other end of the driven rod 132 extends into the receiving cavity of the tabletop assembly 140 and is rotatably supported by the tabletop assembly 140. The linkage mechanism 130, frame 120, and tabletop assembly 140 form a four-bar linkage structure.

[0047] In this embodiment, the active rod 131, the driven rod 132, and the frame 120 are rotatably connected via pins. Preferably, a limit block 121 is fixedly mounted on the frame 120, facing the connecting rod mechanism 130, at a central position to limit the extreme position of the connecting rod mechanism 130. A flexible cushion is provided on the limit block 121 to prevent collision between the connecting rod mechanism 130 and the frame 120.

[0048] The circuit board 160 and wiring harness system are fixedly mounted within the housing of the tabletop assembly 140. A controller and a level angle sensor are integrated into the circuit board 160. The level angle sensor is used to detect the tilt angle of the tabletop assembly 140 relative to the horizontal plane. The level angle sensor is electrically connected to the controller and transmits the detected tilt angle to the controller in real time. The controller controls the drive mechanism 150 based on the data collected by the level angle sensor, causing the drive mechanism 150 to rotate the active rod 131, prompting the linkage mechanism 130 to push the tabletop assembly 140 to flip relative to the frame 120 until the tabletop assembly 140 is horizontal.

[0049] In this embodiment, the table top assembly 140 includes: an upper table top 141, a lower table top 142 and a reinforcing plate 143. The lower table top 142 is fixedly arranged relative to the upper table top 141, and the accommodating cavity is formed between the lower table top 142 and the upper table top 141. The reinforcing plate 143 is located in the accommodating cavity and is fixedly connected to the upper table top 141 by a plurality of bolts. Among them, the upper table top 141 is respectively provided with through slots 141a at the corresponding two connecting rod mechanisms 130, and the through slots 141a are connected to the accommodating cavity, and one end of the active rod 131 and the driven rod 132 extends through the through slots 141a into the accommodating cavity. The circuit board 160 is fixedly mounted on the reinforcing plate 130 to ensure the stability of the circuit board 160.

[0050] The drive mechanism 150 includes a motor 151, a reducer 152, and a transmission shaft 153. The input end of the reducer 152 is connected to the output shaft of the motor 151; the middle portion of the transmission shaft 153 is connected to the output end of the reducer 152, and the ends of the transmission shaft 153 are fixedly connected to the active rods 131 of the two connecting rod mechanisms 130.

[0051] Preferably, the motor 151 is connected to the reducer 152 via a worm gear mechanism. The reducer 152 includes a reduction mechanism composed of multiple helical gears. The gear at the output end of the reducer 152 is ultimately connected to the drive shaft 153, transmitting power to the drive shaft 153. This drive structure 150 ensures stable and smooth power transmission, thereby ensuring the smooth movement of the table assembly 140.

[0052] As a further preferred embodiment, two transmission shaft support bases 170 are provided, which are arranged one-to-one corresponding to the two ends of the transmission shaft 153. The transmission shaft support bases 170 are fixedly connected to the side of the reinforcement plate 143 facing the lower table plate 142, and the two ends of the transmission shaft 153 are rotatably supported in the two transmission shaft support bases 170 respectively.

[0053] A reinforcement 180 is provided between the drive shaft support seat 170 and the lower table board 142; the reinforcement 180 is a Z-shaped plate, the drive shaft support seat 170 is fixedly connected to the bottom plate of the reinforcement 180, and the top plate of the reinforcement 180 is matched with the clips at the edge of the lower table board 142.

[0054] Preferably, two shaft seats 190 are fixedly connected to one side of the reinforcing plate 143 facing the lower table plate 142. The shaft seats 190 are arranged in a one-to-one correspondence with the driven rods 132, and the driven rods 132 are rotatably supported in the shaft seats 190 by shaft pins.

[0055] As a further preference, two electroplated decorative strips are further provided on the table top assembly 140, which are fixedly installed in the accommodating cavity and correspond one-to-one to the position of the through slot 141a. The electroplated decorative strips are composed of a lower decorative strip 144 and an upper decorative strip 145. The top of the lower decorative strip 144 has a groove, and the opening of the groove 144 is set toward the through slot 141a; the upper decorative strip 145 is matched and engaged with the top of the lower decorative strip 144, covering the two side edges of the through slot 141a. The electroplated decorative strips are respectively provided with through holes at the pins corresponding to the transmission shaft 153 and the connecting shaft seat 190, and the pins of the transmission shaft 153 and the connecting shaft seat 190 pass through the corresponding through holes and are connected to the active rod 131 and the driven rod 132.

[0056] In one embodiment, the table top is mounted on the rear side of the backrest of the front seat of the car through the frame mounting plate 110. When the table top needs to be used, the motor is started by the controller to drive the connecting rod mechanism to unfold the table top to a horizontal state. During the use of the table top, the spirit level angle sensor detects the inclination angle of the table top relative to the horizontal plane in real time and transmits it to the controller. The controller controls the rotation of the motor 151 through the encoder based on the data collected by the spirit level angle sensor, thereby rotating the active rod 131, prompting the connecting rod mechanism 130 to push the table top assembly 140 to flip relative to the frame 120, until the spirit level angle sensor detects that the inclination angle of the table top relative to the horizontal plane is 0, and the table top assembly 140 is in a horizontal state. After use, the motor drives the connecting rod mechanism to retract the table top to fit the rear side of the backrest of the front seat of the car.

[0057] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
