Description

Technical Field

[0001] This utility model relates to the field of motor front cover technology, specifically to a motor front cover assembly structure. Background Technology

[0002] The front cover of a motor is an important component of the motor, serving to protect and support the internal components. Its main functions include: preventing dust, dirt, and moisture from entering the motor and ensuring long-term operational reliability; providing necessary support for the motor rotor and maintaining its stability; aiding in heat dissipation, preventing overheating, and extending the motor's service life; and ensuring the airtightness of the internal environment of the motor through sealing rings or other sealing structures to prevent oil or coolant leakage. The main components of the front cover of a motor include the main body, sealing rings, bearing housings, and mounting holes or threads.

[0003] A document with publication number CN202737613U discloses a front end cover for a motor. It includes an end cover body with heat dissipation holes evenly distributed along its circumference, located directly above the motor coils. As can be seen from the above technical solution, this utility model, by creating heat dissipation holes on the end cover body of the motor's front end cover, allows the fan on the pulley to accelerate air convection when the motor rotates. Through the transfer of hot and cold air, heat is carried away from the motor coils, reducing the motor's temperature rise and extending its service life.

[0004] The sealing ring in the front cover of the motor is responsible for sealing and preventing dust and moisture from entering the motor. However, the sealing ring has a service life. Once the sealing ring fails, it will no longer be able to block external dust and moisture, which will cause certain damage to the motor. The aforementioned motor front cover has an inconvenient internal sealing ring replacement, which leads to an extended maintenance time for the sealing ring in the later stages of the motor front cover. Utility Model Content

[0005] The purpose of this utility model is to provide a motor front cover assembly structure that solves the problem that the internal sealing ring of the existing motor front cover is inconvenient to replace, which leads to the extended maintenance time of the sealing ring in the later stage.

[0006] This utility model solves the above-mentioned technical problems through the following technical solution: This utility model includes:

[0007] The front cover has a bearing through hole inside, and a sealing ring is installed inside the bearing through hole. The front of the front cover has two initial entry holes, and each of the two initial entry holes has an arc-shaped channel inside. Each of the two arc-shaped channels has a positioning hole at one end. Each arc-shaped channel has an arc-shaped groove inside, and the two ends of the arc-shaped groove are respectively connected to the initial entry hole and the positioning hole.

[0008] The limiting assembly is arranged on the front surface of the front end cover body, and is used for limiting the sealing ring in the bearing hole.

[0009] Preferably, the two automatic buckle feet are equidistantly distributed on the annular limiting plate, and are used for connecting the annular limiting plate and the front end cover body.

[0010] Preferably, the automatic buckle foot comprises a fixed block fixed on the annular limiting plate, an inner groove is arranged in the fixed block, a magnetic plate is fixed in the inner groove, and a double-inclined-surface magnetic buckle is slidably arranged in the inner groove.

[0011] Preferably, the limiting assembly further comprises two shielding pieces, and the two shielding pieces are arranged at the corresponding positions of the two positioning holes respectively.

[0012] Preferably, the shielding piece comprises a shielding plate hinged to the front surface of the front end cover body and a limiting buckle fixed to the front surface of the front end cover body, the shielding plate and the limiting buckle are arranged on the two sides of the positioning hole respectively, and one side of the shielding plate is fixed with an elastic buckle.

[0013] Preferably, a plurality of ventilation holes and mounting holes are arranged in the front end cover body.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] By arranging the magnetic plate with the same magnetic pole and the double-inclined-surface magnetic buckle, the position of the double-inclined-surface magnetic buckle is limited and automatically reset, so that the double-inclined-surface magnetic buckle can be clamped in the positioning hole to fixedly connect the annular limiting plate and the front end cover body, and the sealing ring shielded and limited by the annular limiting plate can be exposed and replaced for quick disassembly and assembly between the annular limiting plate and the front end cover body, thereby effectively reducing the maintenance time of the sealing ring of the front end cover of the motor.

[0023] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0024] This embodiment provides a technical solution: a motor front end cover assembly structure, such as... Figures 1-5 As shown, the device includes a front cover 1 and a limiting assembly 7. The front cover 1 has a bearing through hole 2 inside, and a slot is formed inside the bearing through hole 2. A sealing ring 3 is set inside the slot and is located inside the bearing through hole 2. The front cover 1 has two initial entry holes 4 on the front side. Each initial entry hole 4 has an arc-shaped channel 5 inside, and a positioning hole 6 is formed at one end of each arc-shaped channel 5. An arc-shaped through groove 10 is formed inside the arc-shaped channel 5. The two ends of the arc-shaped through groove 10 are connected to the initial entry hole 4 and the positioning hole 6, respectively. The front cover 1 has multiple ventilation holes 8 and mounting holes 9 inside.

[0025] The limiting assembly 7 is located on the front side of the front cover 1. The limiting assembly 7 is used to limit the sealing ring 3 within the bearing through hole 2. The limiting assembly 7 includes a limiting member and two blocking members. The limiting member includes an annular limiting plate 71 and two automatically locking feet 72 equidistantly distributed on the annular limiting plate 71. The automatically locking feet 72 are used to connect the annular limiting plate 71 and the front cover 1. The automatically locking feet 72 include a fixing block 721 fixed to the annular limiting plate 71. An inner groove 722 is formed inside the fixing block 721. A magnetic plate 723 is fixed inside the inner groove 722. A double-sloping magnetic buckle 724 slides inside the inner groove 722. The magnetic plate 723 and the double-sloping magnetic buckle 724 have the same magnetic poles on opposite sides. The double-sloping magnetic buckle 724 is pushed out of the inner groove 722 by the principle of repulsion between like magnets. Figure 4As shown, the two slopes of the double-slope magnetic buckle 724 are provided with two slopes, one of which is a large slope, and the starting position of the slope corresponds to the edge of the arc-shaped channel 5 when the fixed block 721 is put into the initial hole 4, which can ensure that when the annular limiting plate 71 is rotated, the double-slope magnetic buckle 724 can be pushed along the arc-shaped channel 5 and slide into the inner groove 722, and one of which is a small slope, and the starting position of the slope is higher than the starting position of the large slope, so that the double-slope magnetic buckle 724 is blocked when it is in the positioning hole 6.

[0026] Two shielding members are respectively arranged at the corresponding positions of the two positioning holes 6, and the shielding member is used to shield the double-slope magnetic buckle 724 to avoid that the double-slope magnetic buckle 724 is accidentally pushed into the inner groove 722 by external objects. The shielding member includes a shielding plate 73 hinged to the front surface of the front end cover body 1 and a limiting buckle 74 fixed to the front surface of the front end cover body 1. The shielding plate 73 and the limiting buckle 74 are respectively arranged on the two sides of the positioning hole 6. One side of the shielding plate 73 is fixed with an elastic buckle 75, and a tension belt for applying tension is arranged on the elastic buckle 75.

[0027] In use: after the sealing ring 3 cannot be effectively sealed, the elastic buckle 75 can be pulled out of the limiting buckle 74 by the tension belt, and then the shielding plate 73 is opened to expose the double-slope magnetic buckle 724 which is shielded inside. The double-slope magnetic buckle 724 is slightly pressed into the positioning hole 6, so that the starting position of the slope of the small slope corresponds to the arc-shaped channel 5. When the double-slope magnetic buckle 724 is pressed, a rotating force is applied to the annular limiting plate 71, so that the double-slope magnetic buckle 724 can slide along the arc-shaped channel 5 into the initial hole 4 after being pressed. In this way, the annular limiting plate 71 can be removed, and the sealing ring 3 is exposed. After a new sealing ring 3 is put into the bearing hole 2, the fixed block 721 is put into the initial hole 4, and the annular limiting plate 71 is rotated. The double-slope magnetic buckle 724 slides into the inner groove 722, and the double-slope magnetic buckle 724 slides to the corresponding position of the positioning hole 6 until the double-slope magnetic buckle 724 is clamped in the positioning hole 6 by the magnetic plate 723. The annular limiting plate 71 and the front end cover body 1 are fixedly installed, and the sealing ring 3 is shielded and positioned, so that the replacement of the sealing ring 3 can be completed. Then, the shielding plate 73 covers the positioning hole 6, and the elastic buckle 75 is buckled on the corresponding limiting buckle 74 by pulling the tension belt, so that some objects are not accidentally poked into the double-slope magnetic buckle 724 to make the double-slope magnetic buckle 724 slide into the inner groove 722, causing the fixing of the annular limiting plate 71 to be loose.

[0028] The above description is only the preferred embodiment of the present application, which is only illustrative but not limiting. It is understood by those skilled in the art that many changes, modifications and even equivalents can be made to the present application within the spirit and scope of the present application, but all will fall within the protection scope of the present application.
