[0030] Specifically, one end of the table plate 3 is hinged with an extended table plate 30, and the extended table plate 30 can be folded to one side of the table plate 3, so that the use area of the table plate can be increased.

[0031] Specifically, one side of the lifting platform 21 is hinged with a cover plate 25 for covering the table plate 3 and the extended table plate 30 into the lifting platform 21, the cover plate 25 can be rotated to the bottom of the extended table plate 30 and used for supporting the extended table plate 30, the cover plate completely covers the lifting platform and the table plate, so that they are hidden in the shell, the visual effect of the car interior is not conspicuous, the appearance is improved, and the cover plate can support the extended table plate after being rotated to the specified position.

[0032] Specifically, the lifting connecting plate 22 is rotatably provided with a damping gear 220 at both ends, the lifting platform 21 is symmetrically provided with a rack 210 on the inner walls of both sides, and the damping gear 220 is arranged on the same side of the rack 210 and meshes with the rack 210, so that the lifting connecting plate has a damping feeling when rising and falling, and the texture is improved.

[0033] Specifically, the lifting platform 21 is fixedly provided with a track groove 211 on both sides, the track groove 211 extends outward to the upper and lower end portions of the side edges of the lifting platform 21 at both ends, and the inner walls of both sides of the shell 1 are fixedly provided with a sliding block shaft 10 used in cooperation with the track groove 211, so that the track groove and the sliding block shaft can guide and limit the rising of the lifting platform.

[0034] Specifically, the first locking device 51 comprises a first unlocking switch 510 rotatably supported in the cover plate 25, a switch lock tongue 511 rotatably arranged on both sides of the inner cavity of the lifting platform 21, a stop slot 512 opened on both sides of the lifting platform 21, a first reset spring 513 fixedly arranged on the inner wall of the shell 1, and a first stop pin 514 fixedly arranged at the end of the first reset spring 513. The bottom of the first unlocking switch 510 extends outward to form a first unlocking end 5100 which abuts against the top end of the switch lock tongue 511. The first stop pin 514 is located at a position corresponding to the position of the stop slot 512, and the end of the first stop pin 514 is inserted into the stop slot 512. The end of the switch lock tongue 511 extends outward to form a second unlocking end 5110 which abuts against the first stop pin 514 on the same side. When the user unlocks the first locking device, the user needs to manually rotate the first unlocking switch. The rotation of the first unlocking switch drives the first unlocking end on both sides to move downward and abut against the top end of the switch lock tongue. The top end of the switch lock tongue is pressed downward by the first unlocking end, so that the switch lock tongue rotates. The rotation of the switch lock tongue drives the second unlocking end to rotate synchronously. The second unlocking end abuts against the first stop pin, so that the first stop pin moves to both sides of the shell. The first stop pin drives the first reset spring to move synchronously and deform. After the first stop pin moves out of the stop slot, the first locking device is unlocked, and the lifting platform is no longer locked and moves upward. The stop slot moves upward synchronously, and the first stop pin is pressed against the side of the lifting platform under the influence of the elastic force of the first reset spring.

[0035] Specifically, the second locking device 52 comprises an opening 520 provided at the bottom end of one side of the lifting platform 21, a second reset spring 521 fixedly arranged in the lifting platform 21, a second stop pin 522 fixedly arranged at one end of the second reset spring 521, a second unlocking switch 523 hingedly arranged at one side of the lifting platform 21, and an unlocking protrusion 524 arranged at the bottom surface of the top end of the shell 1. The end of the second stop pin 522 penetrates through the opening 520 and abuts against one end of the second unlocking switch 523. A reset torsion spring 5230 is sleeved on the second unlocking switch 523. The second unlocking switch 523 extends outward at one side to form a third unlocking end portion 5231. The position of the third unlocking end portion 5231 corresponds to the position of the unlocking protrusion 524. After the first locking device is unlocked, the lifting platform is driven to ascend by the driving device. The second unlocking switch at one side of the lifting platform is synchronously moved upward to abut against the unlocking protrusion at the third unlocking end portion. The lifting platform is moved upward again to the specified position. The unlocking protrusion abutting against the third unlocking end portion moves downward to the left, thereby driving the second unlocking switch to rotate clockwise. The clockwise rotation of the second unlocking switch causes the end of the second stop pin abutting against the end to be pushed into the lifting platform from the opening position. The second reset spring is deformed by the force of the movement of the second stop pin. The second locking device is naturally unlocked. When the lifting platform is forced to move downward, the unlocking protrusion no longer abuts against the third unlocking end portion. The reset torsion spring drives the second unlocking switch to reset. The second unlocking switch is counterclockwise rotated to the original position. The end of the second unlocking switch no longer abuts against the second stop pin. The second reset spring is reset to release the elastic force, thereby driving the second stop pin to move. The end of the second stop pin penetrates through the opening to enable the second locking device to achieve the locking effect.

[0036] Specifically, the third locking device 53 comprises a slider shaft sleeve 531 arranged on the end of the slider shaft 10, a guide sliding groove 532 symmetrically arranged on the end of the lifting connecting plate 22, a through hole 533 arranged on the bottom of the track groove 211, and a lifting lock tongue 534 movably arranged in the lifting platform 21. The slider shaft sleeve 531 is arranged in the track groove 211, the guide sliding groove 532 is arranged to be inclined from the middle of the lifting connecting plate 22 to both sides, the lifting lock tongue 534 is symmetrically arranged in the lifting platform 21, and the end corresponds to the position of the through hole 533. The lifting lock tongue 534 is provided with a lifting lock tongue spring 535 between the lifting lock tongues 534, and the side of the lifting lock tongue 534 is provided with a guide block 5340 which is slidably arranged in the guide sliding groove 532. When the lifting platform is not raised, the position of the slider shaft sleeve is at the top end of the track groove, and the length of the track groove below the through hole is the same as that of the slider shaft sleeve. After the user unlocks the first locking device, the lifting platform is driven to rise by the driving device, the track groove is synchronously raised to the specified position, and the position of the slider shaft sleeve is in the track groove below the through hole. When the user manually moves the lifting connecting plate upwards, the guide block moves downwards along the guide sliding groove, and the lifting lock tongues on both sides move to the positions of the through holes corresponding to them until the ends completely pass through the through holes. At the same time, the lifting lock tongue spring supports the lifting lock tongues on both sides so that they will not be displaced by slight vibration or inertial force. The third locking device is thus locked, so that the lifting platform cannot be lowered. When the user manually moves the lifting connecting plate downwards, the guide block moves upwards along the guide sliding groove, and the lifting lock tongues on both sides move to the middle until the ends are received in the lifting platform. The third locking device is thus unlocked, so that the lifting platform can be lowered.

[0037] Specifically, the driving device 4 is a coil spring driving device. The advantage of using a coil spring as a driving device is that the coil spring does not require an external power supply, the overall maintenance cost is low, and the coil spring can provide controllable restoring force in a small space through spiral deformation.

[0038] The above is only the preferred embodiment of the present application. It should be noted that those skilled in the art can make several improvements and refinements without departing from the technical principles of the present application, and these improvements and refinements should also be considered within the protection scope of the present application.
