[0042] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0043] Reference Figure 1 , 2 The table frame 100, the lifting frame 200, and the side frame 300 slidably mounted on the table frame 100 are included. The side frame 300 is located on both sides of the lifting frame 200. Both the lifting frame 200 and the side frame 300 are provided with tabletops. The lifting frame 200 is provided with a lifting groove 230 along its length. The side frame 300 is provided with a pin 320 that can slide in the lifting groove 230 on the inner side of the end facing the lifting frame 200. The lifting groove 230 includes a long stroke 231, an inclined stroke 232, and a short stroke 233. The short stroke 233 is located at the end parallel to the end of the long stroke 231. The two are connected by the inclined stroke 232. The table frame 100 is provided with a tensioning mechanism. The tensioning mechanism is used to drive the side frame 300 to move relative to the lifting frame 200. After moving in the lifting groove 230 via the pin 320, the two side frames 300 are unfolded or folded onto the lifting frame 200.

[0044] In the embodiment, the lifting groove 230 is specially shaped, that is, the short stroke 233 is located at the end parallel position of the long stroke 231, and the two are communicated through the inclined stroke 232. When the two side frames 300 move relatively, the pin shaft 320 moves in the lifting groove 230 to lift or lower the lifting frame 200. When the lifting frame 200 rises, the lifting frame 200 and the two side frames 300 can be horizontally spread out to increase the unfolded area of the whole telescopic table. When the lifting frame 200 is lowered and the two side frames 300 are closed to the upper end of the lifting frame 200, the area of the whole telescopic table can be reduced. Thus, the practicability and use diversity of the table are improved, and the user experience is better. The stretching mechanism drives the relative movement of the side frames 300 to unfold or fold the telescopic table. The adjustment of the tabletop area of the whole telescopic table is more convenient without manual synchronous pulling of the two side frames 300 to slide. The unfolding and folding of the telescopic table can be conveniently completed, and the operation is more convenient for use of the telescopic table.

[0045] In the embodiment, the table frame 100 can be a cuboid, a cube or other shapes. In the embodiment, the table frame 100 is taken as a cuboid. The table frame 100 is provided with the table leg 130 at the four corners. The stretching mechanism is arranged at the center of the table frame 100.

[0046] Referring to Figure 2 As a specific embodiment of the sliding connection between the side frame 300 and the table frame 100, the inner side of the table frame 100 is provided with the track 120 along the length direction. The bottom of the side frame 300 is provided with the slide rail 310 corresponding to the track 120. The side frame 300 is slidably connected in the track 120 to be slidably connected with the table frame 100.

[0047] In the embodiment, the lifting frame 200 includes the main frame 210 for supporting the tabletop and the mounting plate 220 arranged at the bottom of the main frame 210. The lifting groove 230 is arranged on the outer side of the mounting plate 220. The pin shaft 320 is arranged on the inner side of the slide rail 310 to facilitate the sliding cooperation between the lifting groove 230 and the pin shaft 320.

[0048] In the embodiment, the stretching mechanism includes the rotary driver and the transmission connecting rod 400. The rotary driver is mounted on the table frame 100 and connected with the two side frames 300 through the transmission connecting rod 400 to drive the two side frames 300 to move relatively along the table frame 100. The transmission connecting rod 400 can convert the rotary motion of the rotary driver into the relative sliding of the two side frames 300 along the table frame 100 to facilitate unfolding or folding of the whole telescopic table.

[0049] In the embodiment, the rotating driver can be a common motor 510 or a motor. The following description takes the motor 510 as an example.

[0050] Specifically, in the embodiment, the transmission connecting rod 400 includes a main connecting rod 410 and a sub connecting rod 420 hinged at both ends of the main connecting rod 410. The end of the sub connecting rod 420 away from the main connecting rod 410 is hinged to the side frame 300, and the middle part of the main connecting rod 410 is connected to the output shaft of the motor 510. In this way, the rotation of the motor 510 can drive the rotation of the main connecting rod 410, and then the sub connecting rod 420 on the main connecting rod 410 can drive the relative sliding of the two side frames 300 along the table frame 100.

[0051] In the embodiment, referring to Figure 4 and 5 , in order to facilitate the disassembly and assembly of the main connecting rod 410 and the motor 510, the middle part of the main connecting rod 410 is provided with a mounting block 411, and a non-circular hole is arranged in the mounting block 411. The output shaft of the motor 510 is screwedly connected to the non-circular hole in a screwing manner, so as to realize the convenient assembly of the main connecting rod 410 and the motor 510.

[0052] Based on the above embodiment, referring to Figure 5 , in order to make the rotation of the motor 510 driving the main connecting rod 410 more stable, a rotating disc 520 is arranged between the driving rod and the table frame 100. Specifically, the rotating disc 520 includes an inner disc 522 and an outer disc 521 rotatably arranged outside the inner disc 522. The inner disc 522 is screwedly installed on the table frame 100, the main connecting rod 410 is installed on the outer disc 521, and the motor 510 is arranged at the center of the inner disc 522. When the main connecting rod 410 rotates by the motor 510, the outer disc 521 rotates synchronously on the inner disc 522, thereby providing stable rotating support for the main connecting rod 410.

[0053] In the above embodiment, the stretching mechanism is composed of the motor 510 and the transmission connecting rod 400. It can be conceived that as long as the stretching mechanism can stretch the two side frames 300 to displace the two side frames 300 relative to the lifting frame 200, the stretching mechanism can also be a linear actuator. The linear actuator is used to drive the movement of the two side frames 300. For example, common linear actuators such as electric telescopic rods and hydraulic push rods.

[0055] In the embodiment, the lifting table top 201 is a photovoltaic panel, or a photovoltaic panel is arranged on the lifting table top 201, and the table frame 100 is provided with an energy storage module and a control module, the energy storage module includes a power supply 610, and the control module is a controller 620, the power generated by the photovoltaic panel can be stored in the power supply 610 to supply power to the motor 510, and the controller 620 is used to control the motor 510 to start, and of course, the photovoltaic power generation module can also include an inverter and other components, because the principle is prior art, and will not be described in detail here.

[0056] In the embodiment, the power supply is also provided with an external socket, so that the power supply is charged or directly powered by connecting to the mains through the external socket.

[0057] Based on the above embodiment, the photovoltaic panel can also be selected to be installed on the side table top 301, or the photovoltaic panel directly replaces the side table top 301 and is arranged on the side frame 300, which can also achieve the above effect, and of course, in order to improve the light energy conversion rate, the lifting table top 201 and the side table top 301 can be photovoltaic panels.

[0058] In the embodiment, refer to Figure 3 The limiting block 240 is arranged at the joint of the inclined stroke 232 and the short stroke 233 and at the side edge of the mounting plate 220, so as to limit the movement direction of the pin shaft 320 in the lifting groove 230, and will not be described in detail here.

[0059] Based on the above embodiment, in order to reduce the influence of the table frame 100 on the structure of the lifting table top 201 after the telescopic table is folded, and further optimize the volume after the telescopic table is folded, the middle part of the table frame 100 is provided with a avoiding gap 110, and the front and rear ends of the lifting table top 201 of the telescopic table are embedded in the avoiding gap 110 after the telescopic table is folded.
