[0041] It should be noted that in the claims and description of this patent, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one" do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0042] like Figure 1-Figure 3 As shown, this embodiment discloses a driving mechanism, which includes a base 1, a motor 2, a worm 3, a worm wheel 4 and a transmission gear mechanism.

[0043] The motor 2 has a main body portion 21 and an output shaft 22 .

[0044] In this embodiment, the base 1 is provided with a first installation space 11, a second installation space 12 and a third installation space 13. The first installation space 11 is used to install the main body 21 of the motor 2. The second installation space 12 is used to install the output shaft 22 and the worm 3 of the motor 2. The third installation space 13 is used to install the worm wheel 4 and the transmission gear structure 5.

[0045] The worm 3 is mounted on the output shaft 22 , and the rotation axis of the worm 3 coincides with the axis of the output shaft 22 , that is, the worm 3 and the output shaft 22 are coaxially arranged.

[0046] The worm wheel 4 is rotatably mounted on the base 1 and meshingly connected with the worm 3 .

[0047] The transmission gear structure 5 is connected to the worm wheel 4. In this embodiment, the transmission gear structure 5 is a primary gear structure, which includes a synchronous gear, a non-tooth surface of the synchronous gear is connected to a non-tooth surface 41 of the worm wheel 4, and the synchronous gear is coaxially arranged with the worm wheel 4 so that the synchronous gear can rotate synchronously with the worm wheel 4. In other alternative embodiments, the transmission gear structure 5 can also be a multi-stage gear structure, which is meshed and connected with the worm wheel 4.

[0048] In this embodiment, the rotation of the motor 2 drives the worm 3 to rotate, the worm 3 drives the worm wheel 4 to rotate, the rotation of the worm wheel 4 drives the transmission gear structure 5 to rotate, and the transmission gear structure 5 drives other lower-level mechanisms to move.

[0049] Of course, those skilled in the art should understand that the gear transmission structure is not necessary, and in other alternative embodiments, the worm gear 4 can also directly drive other lower-level mechanisms to move.
