Description

Technical Field

[0001] This utility model relates to the field of motor cover technology, specifically a motor cover with a long service life. Background Technology

[0002] Against the backdrop of rapid development in fields such as new energy vehicles, industrial automation, and high-end equipment manufacturing, the reliability of motors, as core power components, directly affects the operating efficiency and lifespan of equipment. Motor covers, as critical protective components for motors, must simultaneously meet multiple performance requirements, including corrosion resistance, aging resistance, good heat dissipation, and vibration resistance.

[0003] The prior art discloses a motor cover with a long service life, with announcement number CN209786920U. The cover includes a motor cover body, the inner surface of which is integrally injection molded in an annular shape with a first convex ring, the inner surface of which is integrally injection molded in an annular shape with a second convex ring located inside the first convex ring, a reinforcing rib integrally injection molded between the second convex ring and the first convex ring, an oil injection hole at the top of the motor cover body, an oil storage cavity at the upper end of the first convex ring, and an oil guide groove at the bottom of the oil storage cavity connected to the oil guide groove on the inner surface of the motor cover body.

[0004] The aforementioned long-life motor cover, through its structural design including a first convex ring, a second convex ring, reinforcing ribs, an oil injection hole, an oil storage chamber, and an oil guide groove, facilitates oil injection into the shaft hole, achieving oil cooling and improving the heat dissipation efficiency of the motor cover. This allows for timely heat dissipation inside the motor, thereby extending its service life. While this device increases service life through heat dissipation, in actual use, impacts or vibrations causing cracks in the casing can more easily affect the device's lifespan. The aforementioned device lacks components to address these cracks, resulting in an inability to repair cracks and a short service life, leading to poor performance in use. Improvements are needed in this regard. Summary of the Invention

[0005] The purpose of this invention is to provide a motor cover with a long service life to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a motor cover with a long service life, comprising a cover body, wherein a self-healing component is provided on the surface of the cover body, and a surface-reinforced protective component is provided on the surface of the cover body near the bottom.

[0007] The self-healing assembly includes a repair agent storage ring, a replenishment tube, a connecting seat, a connecting threaded section, a sealing cap, a guide tip, a connecting rectangular seat, and a guide ramp. The repair agent storage ring is fixedly connected to the surface of the cap near the center. The replenishment tube is fixedly connected to the top of the repair agent storage ring. The connecting seat is fixedly connected to the top of the replenishment tube. The sealing cap is fixedly connected to the top of the connecting threaded section. The guide ramp is fixedly connected to the inside of the connecting rectangular seat. The guide tip is fixedly connected to the top of the inside of the connecting rectangular seat.

[0008] Preferably, the surface-reinforced protective assembly includes a protective placement plate, a reinforcing plate, a biomimetic honeycomb protective structure, and a connecting ring. The protective placement plate is fixedly connected to the surface of the cover near the bottom, the connecting ring is fixedly connected to the interior of the protective placement plate, the reinforcing plate is fixedly connected to the front of the protective placement plate, and the biomimetic honeycomb protective structure is fixedly connected to the front of the reinforcing plate.

[0009] Preferably, the inner ring of the connector has an internal thread groove, and the connecting thread section is threaded into the interior of the connector.

[0010] Preferably, an elastic ring is fixedly connected to the surface of the repair agent storage ring, and the connecting seat is fixedly connected to the surface of the elastic ring. The placement of the elastic ring causes the vibration of the motor to cause the connecting seat to shake slightly, and the guide tip will also have more contact with the surface of the repair agent storage ring, which can scratch the top of the repair agent storage ring to allow the internal repair fluid to leak out, ensuring the normal use of the device.

[0011] Preferably, the protective placement plate has a groove inside, the area of ​​which is equal to the cross-sectional area of ​​the connecting ring. The groove is adapted to the connecting ring for connection and placement, thereby reducing local stress concentration by dispersing impact force and reducing weight, thus achieving the purpose of protection.

[0012] Preferably, the protective placement plate, the reinforcing plate, and the biomimetic honeycomb protective structure are distributed in a ring at equal intervals on the surface of the connecting ring.

[0013] Preferably, the guide tip is connected to the top surface of the repair agent storage ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This long-life motor cover features a self-healing component. When micro-cracks appear in the motor cover due to vibration or thermal expansion and contraction, the placement of the elastic column causes the motor's vibration to slightly shake the connecting seat. This, combined with the guide tip, scratches the top of the repair agent storage ring, allowing the internal repair fluid to leak out. The repair fluid adheres to the surface of the guide plate and flows downwards to the surface of the housing, automatically filling the cracks. This allows the device to automatically repair cracks and increase its lifespan.

[0015] This long-life motor cover features a surface-reinforced protective assembly. During use, multiple protective placement plates, a front reinforcing plate, and a biomimetic honeycomb protective structure are placed on the connecting ring. This disperses impact force, reduces local stress concentration, and simultaneously reduces weight, thus achieving the purpose of protection and increasing the lifespan of the device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Please see Figure 1-4 The present invention provides the following technical solution: A motor cover with a long service life includes a cover body 1, a self-healing component 2 provided on the surface of the cover body 1, and a surface-reinforced protective component 3 provided on the surface of the cover body 1 near the bottom.

[0020] The self-healing component 2 includes a repair agent storage ring 201, a replenishment tube 202, a connecting seat 203, a connecting threaded section 204, a sealing cap 205, a guide tip 206, a connecting rectangular seat 207, and a guide ramp 208. The repair agent storage ring 201 is fixedly connected to the surface of the cover 1 near the center. The replenishment tube 202 is fixedly connected to the top of the repair agent storage ring 201. The connecting seat 203 is fixedly connected to the top of the replenishment tube 202. The sealing cap 205 is fixedly connected to the top of the connecting threaded section 204. The guide ramp 208 is fixedly connected to the inside of the connecting rectangular seat 207. The guide tip 206 is fixedly connected to the inside of the connecting rectangular seat 207. At the top of the device, the guide tip 206 is connected to the top surface of the repair agent storage ring 201. The inner ring of the connecting seat 203 has an internal thread groove, and the connecting thread section 204 is threaded into the inside of the connecting seat 203. An elastic ring is fixedly connected to the surface of the repair agent storage ring 201, and the connecting rectangular seat 207 is fixedly connected to the surface of the elastic ring. The placement of the elastic ring causes the vibration of the motor to cause the connecting rectangular seat 207 to shake slightly, and the guide tip 206 will also have more contact with the surface of the repair agent storage ring 201, which can scratch the top of the repair agent storage ring 201 to allow the internal repair fluid to leak out, ensuring the normal use of the device.

[0021] The surface-reinforced protective component 3 includes a protective placement plate 301, a reinforcing plate 302, a biomimetic honeycomb protective structure 303, and a connecting ring 304. The protective placement plate 301 is fixedly connected to the surface of the cover 1 near the bottom. The connecting ring 304 is fixedly connected to the inside of the protective placement plate 301. The reinforcing plate 302 is fixedly connected to the front of the protective placement plate 301. The biomimetic honeycomb protective structure 303 is fixedly connected to the front of the reinforcing plate 302. A groove is provided inside the protective placement plate 301. The area of ​​the groove is equal to the cross-sectional area of ​​the connecting ring 304. The groove is adapted to the connecting ring 304 for connection and placement. It reduces local stress concentration by dispersing impact force and reduces weight, thus achieving the purpose of protection. The protective placement plate 301, the reinforcing plate 302, and the biomimetic honeycomb protective structure 303 are distributed in a ring at equal intervals on the surface of the connecting ring 304.

[0022] During use, the cover 1 can be screwed onto the top of the motor. When the motor cover develops micro-cracks due to vibration or thermal expansion and contraction, the placement of the elastic column causes the vibration of the motor to slightly shake the connecting seat 207. The guide tip 206 repeatedly contacts the top surface of the repair agent storage ring 201 and then moves away. This reciprocating operation is repeated multiple times. Depending on the point of force application, the guide tip 206 at the location of the micro-crack will also have more contact with the surface of the repair agent storage ring 201, which can scratch the top of the repair agent storage ring 201, allowing the internal repair fluid to leak out. The reinforcing liquid can be dicyclopentadiene, which adheres to the surface of the guide plate 208 and flows downward to the surface of the shell. It can automatically fill cracks, enabling the device to automatically repair cracks and increase the service life of the device. Furthermore, a surface-reinforced protective component 3 is provided on the bottom surface of the cover 1. During use, multiple sets of protective placement plates 301, as well as the front reinforcing plate 302 and the biomimetic honeycomb protective structure 303 are placed using the connecting ring 304. By dispersing the impact force, the local stress concentration is reduced, and the weight is reduced, thus achieving the purpose of protection. This can protect the cover 1 and increase the service life of the device.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
