[0015] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0016] See Figures 1-4 As shown in the figure, this application discloses a vehicle-mounted electric table, including a controller, an electric actuator 1, a table body 2, and two linkage assemblies arranged symmetrically on the left and right. The table body 2 is located on the rear side of the upper part of the seat back 3. The top of the front end of the table body 2 is provided with two hinge slots 21 arranged symmetrically on the left and right. The electric actuator 1 is fixed to the inner side of the upper part of the seat back 3. Each linkage assembly includes a first linkage 4 and a second linkage 5. One end of each first linkage 4 extends into the hinge slot 21 on the corresponding side and is rotatably connected to the rear part of the hinge slot 21. The other end of each first linkage 4 extends into the seat back 3 and is rotatably connected to the upper part of the seat back 3. One end of each second linkage 5 extends into the hinge slot 21 on the corresponding side and is rotatably connected to the front part of the hinge slot 21. The other end of each second linkage 5 extends into the seat back 3 and is fixed to the output shaft of the electric actuator 1. A control button 6 is fixed on the seat back 3. The electric actuator 1 and the control button 6 are both electrically connected to the controller.
[0017] A gyroscope sensor module is fixed on the inner side of the seat back 3, and the gyroscope sensor module is electrically connected to the controller. With the gyroscope sensor module set, when the table body is in the rotated open state relative to the seat back, and the tilt angle of the seat back is adjusted, the gyroscope sensor module can output an angle signal to the controller. At this time, the controller can control the electric actuator to drive the table body to rotate so that the table body always remains in a horizontal state.
[0018] The table body 2 has a wireless charging module fixed inside. The wireless charging module is electrically connected to the controller. The top of the table body 2 has a recessed wireless charging area 22, which is positioned opposite to the wireless charging module. With this structure, when the table body is rotated open relative to the seat back, the wireless charging module can charge the mobile phone when it is placed in the wireless charging area.
[0019] A light guide strip 23 is fixed at the rear edge of the table body 2, and a light strip is fixed inside the table body 2 opposite to the light guide strip 23. The light strip is electrically connected to the controller. With this structure, the light strip can be lit when the table body is rotated open relative to the seat back. At this time, the light emitted by the light strip can be transmitted through the light guide strip, thereby enhancing the atmosphere inside the car.
[0020] The top of the tabletop body 2 is provided with a recess 24, which is used for the bottom part of the cup to be inserted. With this structure, when the cup is placed on the tabletop body, the bottom of the cup can be inserted into the recess, thereby providing a certain degree of restraint for the cup.
[0021] Both ends of the output shaft of the electric actuator 1 are coaxially connected to drive shafts 12 via couplings 11. The end of each drive shaft 12 away from the coupling 11 is rotatably connected to the seat back 3, and the end of each drive shaft 12 away from the coupling 11 is fixed to the other end of the corresponding second connecting rod 5. With this structure, when the output shaft of the electric actuator rotates, the second connecting rod can be reliably driven to rotate under the action of the coupling and drive shaft, thereby driving the table body to rotate and open or fold relative to the seat back. The electric actuator described above is an existing component on the market and is existing technology, so it will not be described in detail here.
[0022] The working principle of this utility model is as follows: When the control button is pressed, the electric actuator drives the second link to rotate to one side. At this time, with the cooperation of the first link, the table body can rotate and open relative to the seat back. Simultaneously, the light strip can light up, and the light emitted by the light strip can pass through the light guide strip to enhance the atmosphere inside the car. In addition, the power of the wireless charging module is turned on, and when a mobile phone is placed in the wireless charging area, the wireless charging module can charge the mobile phone. When the table body is rotated and opened relative to the seat back, when the tilt angle of the seat back is adjusted, the gyroscope sensor module can output an angle signal to the controller. At this time, the controller can control the electric actuator to drive the table body to rotate so that the table body always remains in a horizontal state. When the control button is pressed again, the electric actuator drives the second link to rotate to the other side. At this time, with the cooperation of the first link, the table body can rotate and fold relative to the seat back. Simultaneously, the light strip can turn off, and the wireless charging module can be powered off.
[0023] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
