As shown in fig. 3 to 5, the supporting device 10 includes a main body 100, and a moving mechanism 200 and a lifting mechanism 300 both provided on the main body 100. The moving mechanism 200 is used for moving and/or supporting an object to be supported, and the lifting mechanism 300 is used for supporting the object to be supported, which is moved by the moving mechanism 200, so as to support the object to be supported independently or in cooperation with the moving mechanism 200. In this embodiment, the supporting device 10 is used for supporting and moving itself, that is, the moving mechanism 200 of the supporting device 10 is used for abutting against a supporting surface such as the ground, so as to move the supporting device 10, and is supported by the supporting device 10. In other embodiments, the supporting device 10 may also support and move other objects to be supported disposed on the supporting device 10, that is, the supporting device 10 is fixed at this time, and the objects to be supported disposed thereon are moved by the moving mechanism 200.

As shown in fig. 3 to 4, the lifting mechanism 300 includes a power unit 310, a lifting unit 320, and a braking unit 330 and a return unit 340 each connected to the lifting unit 320. The power part 310 is used for driving the lifting part 320 to lift, the lifting part 320 moves along the direction of a moving surface facing to or far from the moving mechanism 200 so that the lifting part 320 can support or release an object to be supported, which moves by the moving mechanism 200, the braking part 330 is used for locking the lifting part 320 to be fixed at the current position when triggered, in the embodiment, the braking part 330 is connected with the lifting part 320 through the power part 310 so as to brake the lifting part 320, and after the braking part 330 is manually released under the condition that the power part is powered off, the reset part 340 can provide elastic force to drive the lifting part 320 to move towards the direction of releasing the object to be supported, so that the reset part 340 can release the supported object to be supported. In this way, the resetting portion can reset the lifting portion in various states, for example, after the power portion 310 is powered off, the supporting device 10 can reset the lifting portion 320, and then the object to be supported is moved again by the moving mechanism 200, so as to improve the reliability and the convenience of use of the supporting device 10.

In one embodiment, the power portion 310 obtains the supporting pressure on the supporting surface of the lifting portion through the current, and when the supporting pressure reaches the preset value, the power portion 310 stops driving, and the braking portion 330 triggers to fix the lifting portion 320 at the current position. In this embodiment, the preset value of the supporting pressure is smaller than the pressure of the object to be supported, that is, the lifting portion 320 and the moving portion support the object to be supported together. For example, the sum of the preset pressures of the plurality of elevating portions 320 is half of the pressure of the object to be supported. In other embodiments, the preset value of the supporting pressure may be the same as the pressure of the object to be supported, that is, the object to be supported is supported only by the elevating portion 320. When there are a plurality of lifting units 320, the preset values of the supporting pressures of the lifting units 320 may be the same or different.
