Utility Model Content

[0005] The technical problem solved by this utility model is to provide a highly practical and simple-to-operate automotive fan motor end cover with a relatively simple structure. This solves the problem mentioned in the background art where the disassembly of the motor end cover is cumbersome, leading to complicated motor installation and difficulty in reinforcing the motor end cover, resulting in the motor end cover easily breaking after prolonged use.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an automotive fan motor end cover, including a rear cover, wherein both sides of the inner side wall of the rear cover are provided with snap-fit ​​grooves, and a sliding groove is provided on the other side of the snap-fit ​​groove. A snap-fit ​​block is snapped into the sliding groove, and a front cover is fixedly connected to one side of the snap-fit ​​block. A fixing ring is fixedly connected to one side of the outer surface of the rear cover, and reinforcing rods for increasing toughness are fixedly connected in a ring array at equal intervals on the back of the fixing ring.

[0007] Optionally, the front of the back cover has a cavity, and the cavity is provided with reinforcing ribs to increase stability.

[0008] Optionally, a sealing ring for increasing sealing is fixedly connected to one side of the front cover surface, a fixing bolt is threadedly connected to the center of the front of the front cover, and a connecting disc is threadedly connected to the surface of the fixing bolt.

[0009] Optionally, a hollow tube is inserted into the center of the front of the connecting plate, and the surface of the front cover is threaded.

[0010] Optionally, a threaded tube is threaded to the center of the back cover, and a vent block is provided on the back of the threaded tube.

[0011] Optionally, the surface of the breathable block is embedded with a breathable mesh, and the outer surface of the breathable block is covered with an anti-slip film to increase its anti-slip properties.

[0012] This utility model provides an end cover for an automotive fan motor, which has the following beneficial effects: 1. The automotive fan motor end cover, through the cooperation of the snap-fit ​​groove, sliding groove, snap-fit ​​block and front cover, allows personnel to remove and repair the fan motor. When personnel need to remove the fan motor for maintenance, they can rotate the front cover and snap-fit ​​block clockwise and slide them along the sliding groove to one side of the snap-fit ​​groove. Then, the personnel can pull the front cover outward, thus facilitating the removal of the front cover and rear cover.

[0013] 2. The automotive fan motor end cover, through the setting of the rear cover, fixing ring and reinforcing rod, can strengthen the rear cover when the rear cover is used for too long, thereby increasing its toughness and reducing the occurrence of accidental damage to the rear cover.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figures 1 to 4 The present invention provides a technical solution: an end cover for an automotive fan motor, including a rear cover 1, with snap-fit ​​grooves 2 on both sides of the inner side of the rear cover 1, a sliding groove 3 on the other side of the snap-fit ​​groove 2, a snap-fit ​​block 4 snap-fit ​​inside the sliding groove 3, a front cover 5 fixedly connected to one side of the snap-fit ​​block 4, a hollow tube 12 inserted into the center of the front of the connecting plate 11, and threads on the surface of the front cover 5. When personnel use the automotive fan motor end cover, they can directly place the motor inside the rear cover 1 to install the fan motor. Then, the front cover 5 and the snap-fit ​​block 4 are placed inside the snap-fit ​​groove 2. Subsequently, the snap-fit ​​block 4 slides along the snap-fit ​​groove 2 to the inside of the sliding groove 3 and rotates counterclockwise. Then, the front cover 5 is fixed inside the rear cover 1, which facilitates the personnel to fix the rear cover 1. When the motor is used for a long time, the cooperation between the vent block 14 and the vent mesh allows the vent block 14 to exchange the air inside the rear cover 1 with the outside air, which facilitates the personnel to dissipate heat from the motor. Then, the fixing ring 6 and the reinforcing rod 7 can reinforce the rear cover 1, improve its toughness, and reduce the possibility of the rear cover 1 breaking accidentally due to prolonged use.

[0018] Please see Figures 1 to 4 A fixing ring 6 is fixedly connected to one side of the outer surface of the back cover 1. The back of the fixing ring 6 is fixedly connected with reinforcing rods 7 at equal intervals in a ring array to increase toughness. A cavity is opened on the front of the back cover 1, and reinforcing ribs 8 are set inside the cavity to increase stability. With the back cover 1, the fixing ring 6 and the reinforcing rod 7, when the back cover 1 is used for too long, the fixing ring 6 and the reinforcing rod 7 can strengthen the back cover 1, thereby increasing its toughness and reducing the occurrence of accidental damage to the back cover 1.

[0019] Please see Figures 1 to 4A sealing ring 9 for increasing sealing is fixedly connected to one side of the surface of the front cover 5, and a fixing bolt 10 is threadedly connected to the center of the front of the front cover 5, and a connecting plate 11 is threadedly connected to the surface of the fixing bolt 10. The fixing bolt 10 and the connecting plate 11 facilitate the fixed installation of the front cover 5 by personnel.

[0020] Please see Figures 1 to 4 The back cover 1 has a threaded tube 13 connected to the center of the back side. A breathable block 14 is provided on the back side of the threaded tube 13. A breathable mesh is embedded on the surface of the breathable block 14. An anti-slip film is attached to the outer surface of the breathable block 14 to increase its anti-slip properties. By using the threaded tube 13, when personnel need to disassemble the vent block 14, they can simply twist the vent block 14 to move the threaded tube 13 to disassemble it, thus facilitating its use. In this invention, the working steps of the device are as follows: When personnel use the automotive fan motor end cover, they can directly place the motor inside the rear cover 1 when installing the fan motor. Then, the front cover 5 and the snap-fit ​​block 4 are placed inside the snap-fit ​​groove 2. Subsequently, the snap-fit ​​block 4 slides along the snap-fit ​​groove 2 into the sliding groove 3 and rotates counterclockwise. Then, the front cover 5 is fixed inside the rear cover 1, which facilitates the personnel to fix the rear cover 1. When the motor is used for a long time, the cooperation between the vent block 14 and the vent mesh allows the vent block 14 to exchange the air inside the rear cover 1 with the outside air, which facilitates the personnel to dissipate heat from the motor. Then, the fixing ring 6 and the reinforcing rod 7 can reinforce the rear cover 1, which improves the toughness of the rear cover 1 and reduces the possibility of the rear cover 1 breaking accidentally due to prolonged use.
