Abstract
Description
Technical Field
[0001] This utility model relates to the field of disc motor technology, and in particular to a low-voltage wiring harness outlet device for disc motors. Background Technology
[0002] Currently, the low-voltage wiring harness for motors mainly includes resolver wiring harness and temperature wiring harness. The resolver wiring harness is located on the outside of the motor's rear end cover, while the temperature wiring harness is located inside the motor. Generally, the two wiring harnesses will converge at one point for exiting. Therefore, it is necessary to make a hole in the rear end cover to converge the two wiring harnesses together. After convergence, there are two main exit points: one is on the side of the junction box, and the other is at the resolver protection cover (at the very end of the motor). If the wire exits from the side of the junction box, the resolver wiring harness needs to be threaded into the inside of the end cover. If the wire exits from the protection cover, the temperature wiring harness needs to be threaded into the outside of the motor.
[0003] The solution for routing the cable from the side of the junction box requires drilling a slanted hole at the motor rear cover where the reversible is mounted, and drilling a deep hole downward inside the motor junction box that intersects with the slanted hole. The two holes are close to the water channel, which poses a certain risk of leakage and will restrict the structure of the water channel. This processing solution also allows the cable to route from the side of the motor.
[0004] The solution for routing the wires out at the resolver protection cover often requires introducing the motor temperature rise wires into the resolver protection cover. The drilling location is usually at the resolver stator mounting location, mostly at an angle downwards. This solution is generally done manually, which carries certain risks and may damage the bearing steel sleeve. Utility Model Content
[0005] The technical problem this invention aims to solve is that there is a certain risk of leakage, and it will restrict the structure of the waterway. Manual drilling carries certain risks and may damage the bearing steel sleeve.
[0006] To solve the above-mentioned technical problems, the present invention provides a low-voltage wiring harness outlet device for a disc motor, including an end cover. A resolver protection cover for the disc motor is provided on one side of the surface of the end cover. An installation plate is fixedly installed on the surface of the resolver protection cover. A sealing ring is fixedly installed on the surface of the installation plate near the end cover. The sealing ring is made of rubber. An installation ring is fixedly connected to one side of the surface of the installation plate. The installation ring is installed through the end cover.
[0007] A protrusion is fixedly installed on one side of the surface of the resolver protective cover. A cable outlet box is fixedly connected to the surface of the resolver protective cover near the protrusion. A cable outlet hole is opened on one side of the surface of the cable outlet box. A temperature rise cable channel is opened on the surface of the end cover near the protrusion.
[0008] Preferably, the protrusion has a hollow interior, and the temperature rise line channel is interconnected with the protrusion, which can avoid the mounting hole position of the resolver protection cover and ensure the sealing between the resolver protection cover and the end cover.
[0009] Preferably, the end cap has multiple mounting holes on its surface, which facilitates the installation of the end cap.
[0010] Preferably, the end cap has multiple set screw holes on its surface for motor disassembly.
[0011] Preferably, the surface of the mounting plate is provided with multiple connection holes, which facilitates connection to the end cover by bolts, making it very convenient.
[0012] Preferably, the outlet box and the resolver protection cover are interconnected to ensure that the motor temperature rise wire can be smoothly passed through.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. This utility model optimizes the resolver protection cover by designing a raised structure on the outer ring of the cover, allowing the motor temperature rise wires to pass through the outer ring of the resolver. This greatly reduces the difficulty of end cover processing, effectively avoids the risk of water leakage for the junction box wiring method, avoids the risk of drilling oblique holes for the resolver protection cover wiring, and prevents signal interference caused by the high and low voltage wire bundles being too close. It achieves two goals at once and is worthy of widespread promotion and use, with greater practicality.
[0015] 2. By optimizing the structure of the resolver protection cover, this utility model greatly reduces the processing difficulty of the end cover, avoids potential failure risks, increases the reliability of the motor structure, and is more practical. Attached Figure Description

[0020] Please see Figure 1 and Figure 2 A low-voltage wiring harness outlet device for a disc motor includes an end cover 3. A resolver protection cover 8 for the disc motor is provided on one side of the surface of the end cover 3. An installation plate 7 is fixedly installed on the surface of the resolver protection cover 8. A sealing ring is fixedly installed on the surface of the installation plate 7 near the end cover 3. The sealing ring is made of rubber to ensure better sealing between the resolver protection cover 8 and the end cover 3. An installation ring 11 is fixedly connected to one side of the surface of the installation plate 7. The installation ring 11 penetrates and is installed into the interior of the end cover 3.
[0021] A protrusion 5 is fixedly installed on one side of the surface of the resolver protection cover 8. A cable outlet box 9 is fixedly connected to the surface of the resolver protection cover 8 near the protrusion 5. A cable outlet hole 2 is opened on one side of the surface of the cable outlet box 9 to facilitate the motor temperature rise wire to pass through the cable outlet hole 2 at the cable outlet box 9. A temperature rise wire channel 10 is opened on the surface of the end cover 3 near the protrusion 5. Multiple mounting holes 1 are opened on the surface of the end cover 3. The mounting holes 1 facilitate the installation of the end cover 3. Multiple set screw holes 4 are opened on the surface of the end cover 3 for motor disassembly.
[0022] like Figure 1 As shown, the protrusion 5 has a hollow interior. The temperature rise line channel 10 is interconnected with the protrusion 5, which can avoid the mounting hole 1 of the resolver protection cover 8 and ensure the sealing between the resolver protection cover 8 and the end cover 3. Multiple connection holes 6 are provided on the surface of the mounting plate 7. The connection holes 6 are used to easily connect to the end cover 3 by bolt installation, which is very convenient. The outlet box 9 is interconnected with the resolver protection cover 8 to ensure that the motor temperature rise line can pass through smoothly.
[0023] In use, this utility model utilizes the connecting holes 6 on the surface of the mounting plate 7 to connect the resolver protection cover 8 and the end cover 3 via bolts. The protrusion 5 is hollow and interconnected with the temperature rise line channel 10, allowing the motor temperature rise line to pass through the outer ring of the resolver, greatly reducing the processing difficulty of the end cover 3. It effectively avoids the risk of water leakage for the junction box wiring method, avoids the risk of drilling oblique holes for the resolver protection cover 8 wiring, and avoids signal interference caused by the high and low voltage wire bundles being too close. It avoids the mounting hole 1 position of the resolver protection cover 8 and ensures the sealing between the resolver protection cover 8 and the end cover 3, making it more practical.
