For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] Existing table tops are usually hidden and have lifting and flipping functions. The table top is driven to rise and fall by a lifting motor in conjunction with a lead screw slider structure, and is flipped by a rotating motor in conjunction with a worm gear mechanism. The flipping and lifting need to be driven by two motors separately, which is costly.

[0040] In this regard, this embodiment provides a hidden table top to solve the above problem.

[0041] like Figures 1 to 4 As shown, the hidden table top includes a driving mechanism 1, a table top 2, a track 3 and a sleeve 4. The driving mechanism 1 includes a transmission rod 11 and a driving assembly 12 connected to the transmission rod 11, the transmission rod 11 can rotate relative to the sleeve 4, the table top 2 is installed on the sleeve 4, and the driving assembly 12 can drive the sleeve 4 to move back and forth along the track 3 through the transmission rod 11, thereby realizing the lifting and lowering of the table top 2.

[0042] Specifically, in this embodiment, the track 3 is in the shape of a straight rod and is arranged at an angle. The track 3 includes a rack segment 31 and a straight rod segment 32 connected to the top of the rack segment 31. The sleeve 4 is fixedly connected to the table top 2, and the outer circumferential surface of the sleeve 4 is provided with an incomplete tooth shape 41 and a stop block 42. The incomplete tooth shape 41 includes a plurality of meshing teeth arranged at intervals along the circumferential direction of the sleeve 4. It can be understood that the plurality of fitting teeth of the incomplete tooth shape 41 are only distributed on a part of the circumference of the sleeve 4, and the stop block 42 is located on another part of the circumference of the sleeve 4.

[0043] When the sleeve 4 moves to the rack segment 31, the incomplete tooth shape 41 meshes with the rack segment 31. At this time, as the sleeve 4 continues to move, the sleeve 4 can drive the table top 2 to rotate relative to the track 3. Among them, when the sleeve 4 moves to the rack segment 31 and moves downward, the table top 2 flips upward in the counterclockwise direction and moves closer to the track 3, and at the same time, the stop block 42 gradually moves away from the rack segment 31. When the sleeve 4 moves to the bottom end of the rack segment 31, compared with other positions of the sleeve 4 located at the rack segment 31, the degree of the table top 2 to move closer to the track 3 is the largest. In this embodiment, the table top 2 and the track 3 can be parallel, and the automatic folding of the table top 2 can be achieved.

[0044] When the sleeve 4 moves from the rack section 31 to the straight rod section 32, the incomplete tooth shape 41 rolls with the straight rod section 32. Specifically, in this embodiment, the top surface of each meshing tooth of the incomplete tooth shape 41 can roll relative to the straight rod section 32, and the outer peripheral surface of the sleeve 4 can be clearance-fitted or rolling-fitted with the straight rod section 32. At this time, driven by the gravity of the table top 2, the table top 2 can flip downward in the clockwise direction, and drive the sleeve 4 to rotate relative to the straight rod section 32, until the stop block 42 abuts against the straight rod section 32, and the table top 2 is horizontally unfolded relative to the track 3, so that the table top 2 can be automatically unfolded.

[0045] It should be noted that when the sleeve 4 just leaves the rack end, the stop block 42 still has not yet abutted against the straight rod section 32. The teeth of the rack section 31 are protruding relative to the mating surface of the straight rod section 32 and the incomplete teeth, so that when the sleeve 4 moves from the straight rod section 32 to the rack section 31, the rack section 31 can mesh with the incomplete teeth 41.

[0046] The hidden table top provided in this embodiment realizes automatic folding of the table top 2 by meshing the incomplete tooth shape 41 on the sleeve 4 with the rack segment 31. The incomplete tooth shape 41 rolls with the straight rod segment 32. Under the action of the table top 2's own gravity, the table top 2 drives the sleeve 4 to rotate relative to the straight rod segment 32, thereby realizing automatic unfolding of the table top 2. There is no need to set a flip motor to drive the table top 2 to flip, which can effectively save costs.

[0047] Optionally, the hidden table top further comprises a guide block 5, a rotating shaft 6 and a guide rail 7. The guide rail 7 is provided with a guide groove 71. The length direction of the guide groove 71 is parallel to the length direction of the track 3. The guide block 5 is slidably located in the guide groove 71. The guide block 5 is fixedly connected to the rotating shaft 6. The rotating shaft 6 is rotatably penetrated through the sleeve 4. By providing the guide block 5 and the guide groove 71, when the sleeve 4 moves along the guide rail, the position of the sleeve 4 can be ensured to be stable, especially when the incomplete tooth shape 41 is engaged with the rack segment 31, the sleeve 4 will not deviate from the track 3. Of course, in other embodiments, other methods can be used to prevent the sleeve 4 from deviating from the track 3. For example, a limit plate parallel to the track 3 and spaced apart can be provided. The sleeve 4 moves between the limit plate and the track 3. The limit plate can limit the sleeve 4 from deviating from the track 3.

[0048] Specifically, in this embodiment, the guide groove 71 is rectangular, and the cross section of the guide block 5 is square. Such a configuration can ensure that there is a large contact surface between the guide block 5 and the groove wall of the guide groove 71, thereby preventing the rotating shaft 6 from shaking. In other embodiments, the guide block 5 can also be configured to have a circular cross section.

[0049] Optionally, the guide groove 71 has a first limiting surface 72 and a second limiting surface 73 at both ends of the length direction thereof, and the guide block 5 can be respectively fitted with the first limiting surface 72 and the second limiting surface 73. The first limiting surface 72 and the second limiting surface 73 can limit the range of motion of the sleeve 4.

[0050] Optionally, the transmission rod 11 is rotatably connected to the rotating shaft 6. The transmission rod 11 and the guide rail 7 are respectively arranged on both sides of the sleeve 4, so that the rotating shaft 6 can be ensured to be stably stressed.

[0051] In this embodiment, the driving assembly 12 includes a base 121, a motor 122, a screw 123 and a nut 124. The motor 122 is mounted on the base 121, the screw 123 is connected to the motor 122, the nut 124 is screwed to the screw 123, the screw 123 is connected to the base 121, and the nut 124 is connected to the transmission rod 11. When the motor 122 rotates, the nut 124 is lifted and lowered along the screw 123, and the transmission rod 11 is driven to move by the nut 124, so that the transmission rod 11 drives the sleeve 4 to move on the track 3. In other embodiments, the driving assembly 12 can also be replaced by an electric push rod, a cylinder, etc.

[0052] The extending direction of the screw rod 123 and the extending direction of the transmission rod 11 can be parallel to the length direction of the guide groove 71, and the nut 124 can be directly fixedly connected to the transmission rod 11. The extending direction of the screw rod 123 can also be set at an angle to the extending direction of the guide groove 71. Specifically, the drive assembly 12 also includes a slide 125, which is slidably connected to the transmission rod 11, the screw rod 123 extends in the vertical direction, and the transmission rod 11 extends in the horizontal direction. In this way, the screw rod 123, the transmission rod 11 and the guide rail 7 form a triangular structure, which is more stable.

[0053] Optionally, the hidden table top further includes a mounting frame 8 and a support rod 9 fixedly connected to the mounting frame 8, the base 121 is fixed to the mounting frame 8, and the support rod 9 is fixedly connected to the guide rail 7. Among them, the support rod 9 can be provided in plurality, and the plurality of support rods 9 are arranged in parallel and at intervals, which can enhance the support stability of the guide rail 7. By providing the mounting frame 8, it is convenient to assemble the hidden table top as a whole with other structures of the vehicle as a whole. Preferably, the mounting frame 8 is provided with an avoidance hole 81, the avoidance hole 81 extends in the vertical direction, and the transmission rod 11 is slidably penetrated through the avoidance hole 81.

[0054] This embodiment also provides a vehicle, including the hidden table top in the above solution.

[0055] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
