Description
Technical Field
[0001] The utility model belongs to the technical field of motor waterproofing, and particularly relates to a motor rear end cover that can prevent water and wire detachment. Background Art
[0002] With the highly developed economy, the demand for motors is increasing, and their application scope is also expanding accordingly; among them, for some requirements, the stage lighting equipment has added a lot of motion control, and the key components of these controls, such as the drive motors for horizontal and vertical rotation, tend to use three-phase motors.
[0003] However, the stage lighting equipment is gradually designed more precisely, and the space inside for placing the motor is reduced, and the installation space is limited. However, due to the relatively large waterproof terminal designed on the outer surface of the original motor, the motor cannot be well accommodated in it, and this design usually cooperates with ordinary cable wires. When in use, most users habitually pick up the motor by pulling up the cable wire, and such a picking-up method is likely to drag out the not very firm cable wire, resulting in poor wiring of the internal components of the motor and making the motor unable to work properly.
[0004] At the same time, in the stage environment, the lighting equipment needs to run for a long time and may be exposed to various environments, including accidentally splashed rainwater, other liquids or solvents, etc. If the lighting equipment set on the stage top is accidentally splashed with rainwater, other liquids or solvents, etc., it may cause the motor for its motion control to get water in, easily causing the internal parts of the motor to be corroded and resulting in failures and unable to work properly. Content of the Utility Model
[0005] In order to solve the problems in the above background art, the main purpose of the utility model is to provide a motor rear end cover that can prevent water and wire detachment, which is beneficial to the wire outlet of the encoder, can prevent water vapor from entering the shield, and can also avoid the problem of poor wiring of the internal components of the motor caused by the wire being pulled off.
[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[[ID=#]]
[0027] The following will further describe the present application in detail in conjunction with the attached Figures 1-6 drawings.
[0028] In an embodiment of the present utility model, a motor rear end cover that can be waterproof and prevent the wire from coming out includes a rear end bottom cover 1, a storage component 2, a lead component 3, and several screws 4. The storage component 2 is arranged on the top of the rear end bottom cover 1, and the lead component 3 is fixed to the side wall of the rear end bottom cover 1 by the screws 4. The storage component 2 includes a storage seat 21, a waterproof rubber pad 22, and a storage cover plate 23. The storage seat 21 is arranged on the top of the rear end bottom cover 1 and forms an integrated structure with it. The waterproof rubber pad 22 and the storage cover plate 23 are sequentially arranged on the top of the storage seat 21 and fixed by the screws 4. A waterproof wire groove 24 is arranged on one side of the storage seat 21.
[0029] Among them, the shape of the waterproof rubber pad 22 is adapted to the shape of the top edge of the storage seat 21; the outer shape of the storage cover plate 23 is adapted to the outer shape of the storage seat 21.
[0030] By adding the storage component 2 and the lead component 3 that are convenient for wire passing on the rear end bottom cover 1 in the present utility model, the wires of the components of the motor main body can come out from the waterproof wire groove 24 and the lead component 3, removing the waterproof wiring terminals designed on the surface of the original motor housing, making the motor surface flat and reducing the occupied space, and it can be better installed in equipment with limited space. At the same time, it can also prevent the user from picking up the motor by pulling up the original ordinary cable, avoiding the problem of poor wiring of the internal components of the motor caused by the wire being pulled away.
[0031] The lead component 3 includes several waterproof lead sleeves 31 and a waterproof pressure shell 32. The several waterproof lead sleeves 31 are arranged at intervals between the waterproof pressure shell 32 and the side wall of the rear end bottom cover 1, and the waterproof pressure shell 32 is fixed to the side wall of the rear end bottom cover 1 by the screws 4.
[0032] The side wall of the rear end bottom cover 1 is provided with several lead holes for the components inside the motor except the encoder to lead out the wire. It cooperates with the further included lead component, which can play a role in fixing the wire and prevent the wire led out by the components inside the motor from being pulled away; the bottom ends of the several waterproof lead sleeves 31 are respectively inserted into the several lead holes.
[0033] The waterproof pressure shell 32 is provided with several through holes that are narrow at the top and wide at the bottom. The diameter of the bottom end of the through hole is adapted to the diameter of the top end of the lead sleeve, and the diameter of the top end is smaller than the diameter of the top end of the lead sleeve.
[0034] The waterproof lead sleeve 31 is made of soft rubber material. The top end of it is provided with a threaded structure, and the diameter of the bottom end of it is smaller than the diameter of the lead hole.
[0035] Refer to Figure 4, when threading wires, several wires pass through the lead holes and are respectively sleeved with waterproof lead sleeves 31. The bottom end of the waterproof lead sleeve 31 is inserted into the lead hole. Before insertion, UV glue needs to be applied to better fix the wires and prevent water vapor from entering the rear end cover 1 through the lead hole. Then, the wires sleeved with the waterproof lead sleeves 31 pass through the through holes of the waterproof pressure shell 32 at their corresponding positions. Finally, the waterproof pressure shell 32 is fixed to the waterproof base by screws 4. At this time, several waterproof lead sleeves 31 are squeezed between the through holes of the waterproof pressure shell 32 and the lead holes of the rear end cover 1, and their threaded structures are in a compacted state.
[0036] The top of the receiving seat 21 is open to form a receiving groove, which can be used to accommodate an encoder. A through hole 11 is opened at the inner center of the rear end cover 1 located inside the receiving seat 21 and is connected to the receiving groove, facilitating the wire outlet of the components inside the motor and allowing the rear end of the rotating shaft in the motor to pass through the through hole and be connected to the encoder.
[0037] On the front and rear side walls of the waterproof wire groove 24, several corresponding slots 241 are provided respectively. The slots 241 can be used for the wire passing of the components inside the motor or for the wire passing of the encoder alone. When using this motor rear end cover, the original way of a bundle of ordinary cable wires coming out can be changed to the way of several single high-temperature wires coming out.
[0038] In a specific embodiment of the present invention, after the wires of the components inside the motor come out, waterproof glue is applied to the inner side of the slot 241, so as to further block water vapor in the waterproof wire groove 24 and prevent water vapor from entering the receiving seat 21 and eroding the components inside the motor.
[0039] Refer to Figure 5 , two symmetrically arranged wire groove fixing blocks 25 are placed inside the waterproof wire groove 24. Several double wire grooves are provided at the top or bottom of the wire groove fixing blocks 25. When the two wire groove fixing blocks 25 are symmetrically overlapped, a channel adapted to the wires will be formed, so as to better fix the wires and also play a certain waterproof role.
[0040] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention, and the scope of implementation of the present invention cannot be limited. That is, all equivalent changes and modifications made according to the scope of this application should still fall within the scope covered by the present invention.
