[0030] The bracket 10 provided in the embodiment of the utility model includes, for example, a support member 100, a rotating member 200 and a driving structure 300. Specifically, the rotating member 200 is, for example, connected to one end of the support member 100, and the support member 100 is rotatably connected to an external device through the rotating member 200. The external device here can be, for example, the same as the aforementioned external device. The driving structure 300 is, for example, connected to the rotating member 200, and the driving structure 300 is used to drive the rotating member 200 to rotate relative to the external device, and drive the support member 100 to rotate relative to the external device.

[0031] The support member 100 is made of a durable material, such as metal, plastic or composite material, and is used to provide support. The rotating member 200 is, for example, a rotating shaft, which is used to make the support member 100 rotatable relative to an external device. In some embodiments, the rotating member 200 is, for example, fixedly connected to one end of the support member 100, and is used to drive the rotating member 200 to drive the support member 100 to rotate relative to the external device. The driving structure 300 is, for example, a device that can provide mechanical power, such as an electric motor or a pneumatic motor, and the driving structure 300 is used to drive the rotation of the rotating member 200.

[0032] In some embodiments, the bracket 10 further includes, for example, a first connector 110 and a second connector 120.

Among them, the first connector 110 and the second connector 120 are made of, for example, durable materials, such as plastic or metal, to provide sufficient strength and stability, and the first connector 110 and the second connector 120 are, for example, hinges. The second connector 120 can, for example, be fixedly connected to the support member 100 and the rotating member 200, the first connector 110 can, for example, be movably connected to the rotating member 200, and the first connector 110 is fixedly connected to the external device so that the rotating member 200 can rotate relative to the external device. Of course, in other embodiments, the support member 100 and the external device are rotatably connected, for example, through other applicable connection structures and the rotating member 200, which are not specifically limited here.

[0033] Specifically, the driving structure 300 is connected to the rotating member 200 by mechanical connection (such as transmission methods such as gears, belts, chains, etc.) or other connection methods. When the driving structure 300 is started, the driving structure 300 transmits power to the rotating member 200, and the rotating member 200 drives the support member 100 to rotate around its axis, so that the support member 100 can be opened and closed. It should be noted that the above-mentioned rotation trajectory can be an arc shape, which depends on the design of the bracket 10 and the actual needs of the user, and is not limited here.

[0034] The embodiment of the utility model connects the rotating member 200 by setting a driving structure 300. When the driving structure 300 is started, the driving structure 300 drives the rotating member 200 to rotate relative to the external device, and drives the support member 100 to rotate relative to the external device. The opening and closing process of the support member 100 can be automated, and the design of the rotating member 200 and the driving structure 300 enables the support member 100 to be quickly opened and closed relative to the external device without the need for external force, which is labor-saving and convenient, and can adapt to the requirements of different usage scenarios, with better convenience.

[0035] Reference Figure 1 and Figure 2 The bracket 10 further includes a transmission structure 400, which is, for example, transmission-connected to the rotating member 200 and the driving structure 300. The transmission structure 400 is, for example, a transmission method such as a gear, a belt, or a chain, and is used to drive the rotating member 200 to move through the transmission structure 400 when the driving structure 300 is started.

[0036] Specifically, the transmission structure 400 includes, for example, a first transmission member 410 and a second transmission member 420.

[0037] In some embodiments, reference Figure 3 The first transmission member 410 and the second transmission member 420 are, for example, gear structures. When the driving structure 300 is started, the first transmission member 410 and the second transmission member 420 are meshed. According to the transmission principle of the gear (gear transmission is a mechanical transmission method that uses rotating gears to achieve force transmission and speed change), the driving structure 300 drives the second transmission member 420 to rotate, and the second transmission member 420 drives the first transmission member 410 to rotate through the gear transmission, so that the first transmission member 410 drives the rotating member 200 to rotate, and then drives the support member 100 to rotate relative to the external device.

The end of the rotating member 200 close to the second transmission member 420, for example, is sleeved with a first transmission member 410, and the first transmission member 410, for example, is fixedly connected to the rotating member 200. The driving member 310, for example, transmits force to the first transmission member 410 through the second transmission member 420. In this embodiment, the transmission structure 400 is used to realize the transmission of driving force, thereby driving the rotating member 200 to rotate.
