Technical Field

[0001] This utility model relates to the field of motor accessories technology, specifically a motor end cover with a heat dissipation structure. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It mainly consists of a stator, rotor, housing, fan cover, and end cover. Existing motor end covers are mostly fixed to the motor housing with bolts. A search revealed Chinese patent publication number CN214590925U, which discloses a motor end cover with a heat dissipation structure. The end cover body has four arc-shaped heat dissipation openings evenly distributed around its outer wall. Each arc-shaped heat dissipation opening has an arc-shaped heat-conducting fin on one side. The four arc-shaped heat-conducting fins are connected by a first arc-shaped fin group and three second arc-shaped fin groups. The first arc-shaped fin group includes two first arc-shaped fins, and each second arc-shaped fin group includes two second arc-shaped fins. A heat dissipation fin is attached to the outer side of each arc-shaped heat-conducting fin.

[0003] While the above-mentioned technical solutions have good heat dissipation effect and can meet the heat dissipation needs in different environments, dust will adhere to the surface of the heat dissipation fins during use, which will affect the heat dissipation effect. Furthermore, it is inconvenient to clean the dust on the surface of the heat dissipation fins in the above-mentioned technical solutions, and the bolts for installing the end cover cannot be tightened during installation, which can easily loosen due to motor vibration. Utility Model Content

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a motor end cover with a heat dissipation structure, including an end cover body, a plurality of heat dissipation fins are fixedly connected to the outer surface of the end cover body in a ring, a cleaning mechanism that cooperates with the heat dissipation fins is installed on the outer surface of the end cover body, a plurality of connecting ears are fixedly connected to the outer surface of the end cover body in a ring array, an installation hole is opened on the outer surface of the connecting ears, and a self-locking mechanism is installed on the outer surface of the connecting ears.

[0006] The cleaning mechanism includes a movable ring located on one side of the end cap body. Scrapers are attached to both sides of the outer surface of the heat dissipation fins, and one end of the scraper is fixedly connected to the inner wall of the movable ring.

[0007] Preferably, a plurality of return springs are fixedly connected between one side of the outer surface of the moving ring and the end cap body, and the return springs facilitate the automatic reset of the moving ring and the scraper.

[0008] Preferably, the outer surface of the end cap body is provided with a plurality of storage holes that cooperate with the reset spring, so as to facilitate the storage of the reset spring.

[0009] Preferably, the self-locking mechanism includes a ratchet fixedly connected to the outer surface of the connecting ear. The ratchet has a turntable inside that is rotatably connected to the outer surface of the connecting ear. The outer surface of the turntable has a regular hexagonal hole for placing bolts. The outer surface of the turntable is rotatably connected to a one-way ratchet tooth that cooperates with the ratchet, which can lock the bolts of the end cap and prevent them from loosening.

[0010] Preferably, a pin is rotatably connected to the outer surface of the one-way ratchet, and one end of the pin is connected to the internal thread of the turntable, which facilitates the disassembly of the one-way ratchet.

[0011] Preferably, a torsion spring is fitted on the outer surface of the pin, and the two ends of the torsion spring are respectively engaged with the outer surfaces of the pin and the turntable to facilitate the automatic reset of the one-way ratchet.

[0012] This utility model provides a motor end cover with a heat dissipation structure. It has the following beneficial effects:

[0013] This motor end cover with a heat dissipation structure uses a cleaning mechanism where the moving ring can drive multiple scrapers to move, thereby removing dust and other debris adhering to the surface of the heat dissipation fins and preventing them from affecting the heat dissipation effect.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] like Figures 1 to 3 As shown, a motor end cover with a heat dissipation structure includes an end cover body 1. Multiple heat dissipation fins 2 are annularly fixedly connected to the outer surface of the end cover body 1. A cleaning mechanism 3, cooperating with the heat dissipation fins 2, is installed on the outer surface of the end cover body 1. The cleaning mechanism 3 includes a movable ring 31 located on one side of the end cover body 1. Scraper strips 32 are attached to both sides of the outer surface of the heat dissipation fins 2, and one end of each scraper strip 32 is fixedly connected to the inner wall of the movable ring 31. Multiple return springs 33 are fixedly connected between one side of the outer surface of the movable ring 31 and the end cover body 1. Multiple receiving holes 34, cooperating with the return springs 33, are provided on the outer surface of the end cover body 1.

[0023] When in use, if a lot of dust adheres to the heat dissipation fins 2 and affects the heat dissipation of the end cover body 1, the moving ring 31 can be pulled. The movement of the moving ring 31 can drive the multiple scrapers 32 to move, thereby scraping away the dust and other dust adhering to the surface of the heat dissipation fins 2, so as to avoid affecting the heat dissipation effect. Under the action of the return spring 33, the moving ring 31 and the scrapers 32 can be automatically reset.

[0024] like Figure 1 and Figure 4 As shown, a plurality of connecting ears 4 are fixedly connected in a circular array on the outer surface of the end cap body 1. The outer surface of each connecting ear 4 has mounting holes, and a self-locking mechanism 5 is installed on the outer surface of each connecting ear 4. The self-locking mechanism 5 includes a ratchet 51 fixedly connected to the outer surface of the connecting ear 4. Inside the ratchet 51 is a turntable 52 rotatably connected to the outer surface of the connecting ear 4. The outer surface of the turntable 52 has a regular hexagonal hole 53 for placing bolts. A one-way ratchet tooth 54, which cooperates with the ratchet 51, is rotatably connected to the outer surface of the turntable 52. A pin 55 is rotatably connected through the outer surface of the one-way ratchet tooth 54, and one end of the pin 55 is threaded into the inner surface of the turntable 52. A torsion spring is sleeved on the outer surface of the pin 55, and both ends of the torsion spring are respectively engaged with the outer surfaces of the pin 55 and the turntable 52.

[0025] When installing the end cap body 1, insert the bolt into the regular hexagonal hole 53 on the turntable 52. After the end cap body 1 is fixed by rotating the bolt, the one-way ratchet 54 will be engaged in the ratchet 51 under the action of the torsion spring, which can lock the bolt and prevent the bolt from loosening due to motor vibration during use. When disassembling, the bolt can be removed by first removing the pin 55 and the one-way ratchet 54 through the thread.

[0026] Specifically, before bolt installation, appropriate rubber or elastic gaskets can be placed in the regular hexagonal hole 53 to exert a squeezing effect on the bolt and end cap body. In conjunction with the locking mechanism 5, the bolts can be prevented from loosening while ensuring the stable connection of the end cap body 1.

[0027] Working principle: When in use, if a lot of dust adheres to the heat dissipation fins 2 and affects the heat dissipation of the end cover body 1, the moving ring 31 can be pulled. The movement of the moving ring 31 can drive multiple scrapers 32 to move, thereby scraping away the dust and other dust adhering to the surface of the heat dissipation fins 2, so as to avoid affecting the heat dissipation effect. Under the action of the return spring 33, the moving ring 31 and the scrapers 32 can be automatically reset.

[0028] When installing the end cap body 1, insert the bolt into the regular hexagonal hole 53 on the turntable 52. After the end cap body 1 is fixed by rotating the bolt, the one-way ratchet 54 will be engaged in the ratchet 51 under the action of the torsion spring, which can lock the bolt and prevent the bolt from loosening due to motor vibration during use. When disassembling, the bolt can be removed by first removing the pin 55 and the one-way ratchet 54 through the thread.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
