DETAILED DESCRIPTION
[0022] The utility model discloses a motor brake structure, which is described in conjunction with the preferred embodiment (embodiment 1) and the accompanying drawings. Figures 1 to 6 , the specific implementation methods of the utility model are further described.
[0023] See attached figure Figures 1 to 6 , Figures 1 to 3 The motor brake structure from different perspectives is shown. Figures 4 to 6 The partial structures of the motor brake structure are shown respectively.
[0024] Example 1.
[0025] Preferably, the motor braking structure is used to forcibly brake the motor 1 in an emergency. The motor braking structure includes a longitudinal positioning rod 110, a transverse positioning rod 120, a motor fixing assembly 200 and a motor stop assembly 300, wherein:
[0026] The longitudinal positioning rod 110 and the transverse positioning rod 120 are perpendicular to each other and fixedly connected;
[0027] One side of the motor fixing assembly 200 is slidably connected to the longitudinal positioning rod 110, and the other side of the motor fixing assembly 200 is detachably connected to the motor 1;
[0028] The motor stop assembly 300 includes a first positioning member 310, a first positioning rod 320, a second positioning member 330 and a third positioning member 340. One side of the first positioning member 310 is fixedly connected to the longitudinal positioning rod 110, and the other side of the first positioning member 310 is fixedly connected to (one end of) the first positioning rod 320. The second positioning member 330 is located between the third positioning member 340 and the first positioning rod 320. The second positioning member 330 is fixedly connected to the third positioning member 340, and the second positioning member 330 is slidably connected to the first positioning rod 320.
[0029] The first positioning member 310 is provided with a clutch 350 and a rotating rod 360 on both sides. The clutch 350 is in transmission connection with the rotating rod 360. The third positioning member 340 has a plurality of rotating rod positioning holes 341. The rotating rod 360 is internally connected to the insert 370. The insert 370 is internally connected to one of the rotating rod positioning holes 341 of the third positioning member 340.
[0030] When the motor 1 needs to be forcibly braked by the motor brake structure (for example, when a power supply anomaly occurs), the motor fixing assembly 200 is slid along the longitudinal positioning rod 110, causing the toothed portion 2 of the motor 1 to engage with the engager 350 of the motor stop assembly 300, thereby driving the rotation rod 360 to rotate. The rotation rod 360 and the insert 370 rub against each other and have a tendency to further drive the insert 370 to rotate. Because the insert 370 is constrained by the third positioning member 340, the rotation of the rotation rod 360 is converted into linear motion of the insert 370, the third positioning member 340, and the second positioning member 330 along the first positioning rod 320, thereby accelerating the energy dissipation process of the motor 1 until the motor 1 naturally stops. Thereafter, the insert 370, the third positioning member 340, and the second positioning member 330 can be returned to their initial positions relative to the first positioning rod 320 to create the necessary conditions for the next forced braking of the motor 1.
[0031] The meshing device 350 is provided with a meshing portion 351 , and the meshing portion 351 is provided with a plurality of external teeth 352 , and the external teeth 352 are adjacent to each other, so that the meshing portion 351 can mesh with the toothed portion 2 .
[0032] Among them, the coupler 350 is also provided with (two) protective plates 353, which are arranged on both sides of the meshing portion 351; so that the meshing portion 351 is protected from external interference, and can guide the toothed portion 2 to approach the meshing portion 351 in the process of approaching the meshing portion 351.
[0033] The outer surface of the rotating rod 360 is provided with an external thread 361 so as to enhance the degree of friction between the rotating rod 360 and the insert 370 and accelerate the energy dissipation of the motor 1 .
[0034] Among them, the motor fixing assembly 200 includes a connecting piece 205, a main body piece 202 and two extension pieces 201 integrally formed with the main body piece 202. The extension pieces 201 are arranged on both sides of the main body piece 202. The connecting piece 205 is fixedly connected to the extension piece 201 and the main body piece 202 at the same time. The connecting piece 205 is slidably connected to the longitudinal positioning rod 110.
[0035] The main body piece 202 has a motor alignment hole 204 for accommodating the tooth-shaped portion 2 so as to expose the tooth-shaped portion 2 .
[0036] One of the extension pieces 201 has a meshing device alignment hole 203 so that the toothed portion 2 and the meshing portion 351 can mesh with each other.
[0037] It is worth mentioning that the technical features such as the specific model of the motor 1 involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected by conventional means in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated.
[0038] For those skilled in the art, it is still possible to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model should be included in the scope of protection of the present utility model.
