DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides a technical solution: a motor rear end cover with a positioning and installation structure, comprising a back plate 1, a functional component 200 is installed on the front of the back plate 1, and the motor cover can be quickly positioned and installed through the mutual use of the back plate 1 and the functional component 200, without the need for repeated rotation for alignment, thus saving installation time and the energy of the installers, and no offset will occur after the installation is completed, thereby improving the safety of use, and at the same time, through the provision of multiple reinforcement mechanisms, the strength of the motor rear end cover can be improved, so that the service life of the motor rear end cover is increased, thereby improving the practicality of the motor rear end cover.

[0024] In this embodiment, the functional component 200 is a structure for quickly positioning and installing the motor cover.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the functional component 200 includes an annular mounting sleeve 201 fixedly connected to the front of the back plate 1, the outer surface of the annular mounting sleeve 201 is fixedly connected to the connecting ear plates 203 that are evenly distributed, the front of the connecting ear plates 203 is provided with threaded holes 202, the front of the back plate 1 is fixedly connected to the bearing mounting ring 204, the outer surface of the bearing mounting ring 204 is fixedly connected to the connecting ribs 205 that are evenly distributed, the front of the back plate 1 is provided with threading holes 206, and the front of the back plate 1 is fixedly connected to four evenly distributed fixing columns 208, the four fixing columns 209 are fixedly connected to the four fixing columns 201. The inner rear side walls of 08 are fixedly connected with springs 213, the inner rear side walls of the four fixed columns 208 are fixedly connected with dampers 214, the front of the spring 213 is fixedly connected with a movable plate 212, the front of the four movable plates 212 are fixedly connected with telescopic columns 209, the back of the back plate 1 is fixedly connected with a connecting block 210, the outer surface of the connecting block 210 is fixedly connected with uniformly distributed reinforcing ribs 211, and the inner rear side wall of the bearing mounting ring 204, the back of the connecting block 210 and the back of the bearing mounting ring 204 are all provided with circular holes 207.

[0026] It should be noted that the bearing mounting ring 204 and the connecting rib 205 are both located inside the annular mounting sleeve 201, so that the annular mounting sleeve 201 protects the internal bearing mounting ring 204 and the connecting rib 205, and the diameters of the three circular holes 207 are equal, which facilitates the stable rotation of the output end of the motor.

[0027] In addition, the bearing mounting ring 204 is a hollow cylinder with a missing front side, which facilitates the installation of the bearing inside the bearing mounting ring 204, thereby allowing the motor output shaft to rotate stably. There are four reinforcing ribs 211, and the front side of the reinforcing rib 211 is fixed to the back side of the back plate 1. The side of the connecting rib 205 away from the bearing mounting ring 204 is fixed to the inner wall of the annular mounting sleeve 201, and the back side of the connecting rib 205 is fixed to the front side of the back plate 1. By using the reinforcing ribs 211 and the connecting ribs 205, the rear end cover of the motor can be made stronger during use, which is convenient for long-term use of the rear end of the motor.

[0028] Secondly, the front sides of the four fixed columns 208 are all provided with moving holes for the telescopic columns 209 to move. The diameter of the moving holes is equal to the diameter of the telescopic columns 209, which is convenient for the telescopic columns 209 to move telescopically inside the fixed columns 208, thereby allowing the rear end cover of the motor to be installed. At the same time, the telescopic columns 209 and the fixed columns 208 are inserted into the interior of the motor, and can be quickly positioned and installed.

[0029] In addition, the diameter of the movable plate 212 is larger than the diameter of the movable hole, which prevents the telescopic column 209 from detaching from the interior of the fixed column 208. The damper 214 is located inside the spring 213. Through the use of the damper 214, the spring 213 inside the rear end cover of the motor will not vibrate due to the vibration of the motor after installation. The damper 214 is used to reduce shock and buffer the damage.

[0030] The working principle of the above embodiment is as follows: when using the rear end cover of the motor with a positioning installation structure, first align the multiple telescopic columns 209 on the front side of the rear end cover of the motor and insert them into the interior of the motor. Because the front side of the telescopic columns 209 is located on the front side of the annular installation sleeve 201, the positions of the four telescopic columns 209 can be seen during the installation process, so that the staff can insert the four telescopic columns 209 into the interior of the motor at the same time, and then insert the fixed column 208 into the interior of the motor. At the same time, the telescopic column 209 drives the movable plate 212 to move, so that the spring 213 and the damper 214 are squeezed, so that the front side of the annular installation sleeve 201 can be fitted with the motor, and then the four connecting ear plates 203 are threadedly connected to the motor by bolts, so that quick positioning and installation can be carried out.

[0031] Compared with the prior art, the rear end cover of the motor with a positioning and mounting structure can be quickly positioned and installed through the cooperation of the back plate 1 and the functional component 200, without the need for repeated rotation for alignment, thus saving installation time and the energy of the installers, and no offset will occur after the installation is completed, thereby improving the safety of use. At the same time, through the provision of multiple reinforcement mechanisms, the strength of the rear end cover of the motor can be improved, and the service life of the rear end cover of the motor is increased, thereby improving the practicality of the rear end cover of the motor, and solving the problem that during use of the existing camera cover, the end cover and the generator need to be repeatedly rotated to determine whether the end cover and the generator are installed in position, and the installation process consumes a lot of time to align the holes, wasting installation time and the energy of the installers.

[0032] It should be noted that the terms "include", "comprises" or any other variations 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, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
