Description

Technical Field

[0001] This utility model relates to the field of motor housing technology, and in particular to a sealed motor housing with integrated wiring channels. Background Technology

[0002] Electric motors are common power equipment in industrial production. The operation of an electric motor requires the connection of power lines and control lines. These lines need to be led out from inside the motor housing and connected to external equipment. In the current technology, these led-out lines are simply bundled outside the motor or stored in external cable trays. This method results in messy external wiring, which not only affects the appearance, but also causes the wiring to wear or loosen in a vibration environment, making it inconvenient for later inspection and maintenance.

[0003] Furthermore, in order to lead the wiring out of the housing, through holes must be made on the motor housing. The existing sealing method is to install simple rubber rings or gaskets at the through holes. When multiple wires pass through together, the gaps between the wires are difficult to fill effectively, causing external dust, oil, or moisture to enter the motor through the gaps, which seriously affects the insulation performance and service life of the motor. At the same time, the motor housing itself, such as the joint between the front cover and the rear cover, also relies on traditional gaskets for sealing. Under long-term vibration and thermal expansion and contraction, this sealing method will also produce gaps, further reducing the overall protection level of the motor.

[0004] Therefore, this utility model proposes a sealed motor housing with integrated wiring channels to overcome the shortcomings of the prior art. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] Example: Please refer to Figures 1 to 4This utility model provides a sealed motor housing with an integrated wiring channel, including a front cover 1, a rear cover 301, a wiring mechanism 2, and a sealing mechanism 3. A cavity 201 is formed inside the front cover 1. The wiring mechanism 2 is disposed on the top of the front cover 1. The sealing mechanism 3 connects the front cover 1 and the rear cover 301, forming a complete mechanism. The sealing mechanism 3 includes a built-in magnetic strip 302 fixedly connected to the inner wall of the right end of the cavity 201, the built-in magnetic strip 302 having strong attraction. The sealing mechanism 3 also includes a strong magnetic attraction disposed on the inner wall of the left end of the rear cover 301. The sheet 303 has a built-in magnetic strip 302 that can form a strong attraction with the strong magnetic attracting sheet 303. The right end of the front cover 1 has a limiting groove 304 and the left end of the rear cover 301 has a limiting block 305. When the left side of the rear cover 301 and the right side of the front cover 1 are pressed together, a magnetic attraction force will be generated. The limiting block 305 and the limiting groove 304 are engaged to form a radial limit and complete the seal. After the rear cover 301 and the front cover 1 are engaged, a ring of engaging groove 306 will be formed on the surface. The sealing mechanism 3 also includes a fastening ring 307. The fastening ring 307 is installed in the engaging groove 306 to form an external sealing structure and a multi-layer seal.

[0020] Please refer to Figure 3 and Figure 4 The wiring mechanism 2 is located on the top of the front cover 1 and is used to organize the internal wiring. The wiring mechanism 2 includes a hub plate 202, which penetrates the top of the front cover 1 and connects the inside and outside.

[0021] Please refer to Figure 3 and Figure 4 The wiring mechanism 2 includes a hub plate 202, a plug plate 206, and a fixing bolt 209. The hub plate 202 is fixedly connected to the top of the front cover 1. A through groove 203 is provided at the bottom of the hub plate 202, which penetrates the front cover 1 housing, allowing the internal wiring of the motor to be led out. A sealing cotton 204 is fixedly connected inside the through groove 203. The internal wiring of the motor must pass through the sealing cotton 204. The sealing cotton 204 is used to prevent dust from entering the cavity 201 of the front cover 1 from the wiring gaps, thus sealing the wiring entrance. Furthermore, a locking block 2 is provided on the inner wall of the hub plate 202. 05. The locking block 205 is set on the front and rear sides of the inner wall of the hub plate 202. The insert plate 206 is installed on the locking block 205 by sliding connection. The gap reserved between the insert plate 206 and the hub plate 202 forms the cable passage groove 207. The cable passage groove 207 is used to accommodate and guide the line. The fixing bolt 209 is installed on the top of the insert plate 206 by threaded connection. The fixing bolt 209 passes through the insert plate 206 and is connected to the hub plate 202. By rotating the fixing bolt 209, the insert plate 206 can be firmly fixed, thereby pressing and fixing the line in the cable passage groove 207.

[0022] As a preferred implementation method, to improve wiring flexibility to accommodate different cables, please refer to... Figure 4 The hub plate 202 has through holes 208 on both the left and right sides, and the through holes 208 are connected to the through groove 203 at the bottom.

[0023] As a preferred embodiment, to ensure the stability of the sliding connection of the insert plate 206, please refer to... Figure 4 The locking block 205 is specifically set on the front and rear sides of the inner wall of the hub plate 202 to provide a stable sliding track for the insert plate 206.

[0024] As a preferred embodiment, in order to achieve magnetic attraction of the sealing mechanism 3, please refer to... Figure 2 The built-in magnetic strip 302 is preferably fixedly connected to the inner wall of the right end of the cavity 201.

[0025] In a preferred embodiment, in order to cooperate with the built-in magnetic strip 302, the strong magnetic absorbing piece 303 is preferably disposed on the inner wall of the left end of the rear end cover 301. When the rear end cover 301 is close to the front end cover 1, the built-in magnetic strip 302 and the strong magnetic absorbing piece 303 are facing each other.

[0026] In a preferred embodiment, in order to achieve radial positioning of the front cover 1 and the rear cover 301, a limiting groove 304 is provided at the right end of the front cover 1.

[0027] In a preferred embodiment, a limit block 305 is provided at the left end of the rear cover 301 to cooperate with the limiting groove 304 for engagement.

[0028] Furthermore, in the preferred embodiment, the engagement of the limiting block 305 and the limiting groove 304 forms a reliable radial limit, preventing the rear cover 301 from rotating circumferentially or misaligning relative to the front cover 1.

[0029] Furthermore, in the preferred embodiment, the strong attraction formed between the built-in magnetic strip 302 and the strong magnetic absorbing piece 303 ensures that the front cover 1 and the rear cover 301 can automatically attract and maintain a tight fit during installation, providing convenience for the subsequent installation of the fastening ring 307.

[0030] As another preferred embodiment, to accommodate different types of lines, the hub 202 is provided with through holes 208 on both the left and right sides. The through holes 208 are connected to the through grooves 203 at the bottom, providing alternative channels for small or special lines.

[0031] Working principle: When internal wiring needs to be sorted, the various wires inside the motor are first introduced through the through groove 203 at the bottom of the hub plate 202. As the wires are introduced, they pass through the sealing cotton 204 fixedly connected inside the through groove 203. The sealing cotton 204 elastically compresses the outer periphery of the wires, effectively preventing external dust from entering the cavity 201 of the front cover 1 along the wire gaps, thus achieving the first layer of sealing at the wire entry point. After passing through the sealing cotton 204, the wires enter the interior of the hub plate 202. At this point, the operator places different wires on the connection between the insertion plate 206 and the hub plate 202. Within the different cable grooves 207 formed between the cable boards 202, the relative positions of the lines are adjusted by sliding the insert plate 206. After the position is determined, the fixing bolt 209 at the top of the insert plate 206 is rotated. The fixing bolt 209 is tightened by the thread, passes through the insert plate 206 and abuts against the cable hub 202, thereby firmly fixing the insert plate 206. The insert plate 206 then presses the lines in the cable grooves 207, achieving orderly sorting and reliable fixing. For some small lines or lines that cannot be squeezed, they can be connected outward from the through holes 208 on the left and right sides of the cable hub 202. When sealing the main body of the housing is required, align the left end of the rear cover 301 with the right end of the front cover 1 and bring them close together. Since the inner wall of the cavity 201 of the front cover 1 is equipped with a built-in magnetic strip 302, and the inner wall of the rear cover 301 is equipped with a strong magnetic attraction piece 303, a strong magnetic attraction force will be automatically generated when the two are close together, causing the rear cover 301 to fit tightly against the front cover 1. During the process of magnetic attraction and tight bonding, the limiting block 305 on the rear cover 301 will automatically engage with the limiting groove 304 on the front cover 1. The engagement of 05 with the limiting groove 304 forms a reliable radial limit, preventing the rear cover 301 from rotating or misaligning relative to the front cover 1, thus completing the first layer of internal shell sealing. After the front cover 1 and the rear cover 301 are fully engaged, a ring of engagement groove 306 will be formed on the mating surfaces of the two. At this time, the fastening ring 307 is fitted and installed in the engagement groove 306. The fastening ring 307 forms a strong mechanical fastening and external sealing structure on the outside, realizing the second layer of external shell sealing.
