Description

Technical Field

[0001] The present invention relates to the field related to motors, and specifically to a motor heat dissipation housing structure. Background Art

[0002] A motor is an electromagnetic drive device that converts electrical energy into mechanical energy. Motors are divided into two types: DC motors and AC motors. Among them, in new energy electric products such as electric vehicles and drones, DC motors are commonly used and are directly powered by an internal battery pack.

[0003] Since such new energy electric products are in a relatively enclosed form, the motors inside are basically in a closed environment during daily use. Therefore, the heat dissipation of the motor is relatively poor, and dust is also likely to accumulate on the surface of the motor, especially on the heat dissipation fins, affecting subsequent use and normal heat dissipation. Summary of the Invention

[0004] The purpose of the present invention is to provide a motor heat dissipation housing structure to solve the above problems.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: A motor heat dissipation housing structure includes a housing, on which several mounting feet are fixed. An inner cavity is opened in the housing, and at least one fixing seat is fixed in the inner cavity. The fixing seat is fixed to the motor feet on the motor, and there are fins on the motor:

[0006] A gas guiding component is installed on one side of the housing. The gas guiding component includes a gas guiding pipe component fixedly communicating with the inner cavity and a gas guiding head at one end of the gas guiding pipe component. The gas guiding head communicates with the external space;

[0007] The gas guiding pipe component includes a pair of fixing pieces fixed to the housing. A shunt pipe is fixedly installed between the two fixing pieces. One end of the shunt pipe is fixedly connected to a joint, and the other end of the shunt pipe is fixedly connected to at least one shunt nozzle. The end of the shunt nozzle is located in the inner cavity and is fixedly connected to a diffuser nozzle. A hose is fixedly installed on the joint, and the hose is fixedly connected to the gas guiding head.

[0008] Preferably, the diffuser nozzle consists of a base and a diffuser head. The base is fixedly connected to the diffuser head. One end of the base is fixedly connected to the shunt nozzle, and this end is designed in a conical shape. The side of the diffuser head close to the base is designed in an inwardly concave shape, and dry diffusion holes are opened on the diffuser head.

[0009] Preferably, several gas guiding plates are fixedly installed on the top of the inner cavity. Each gas guiding plate is arranged in a stepped manner, and each gas guiding plate has a curved surface on the side facing the gas guiding pipe component.

[0010] Preferably, a cleaning ring is installed outside the motor. Connectors are fixed at both ends of the cleaning ring. One end of each connector is fixed on a slider, which is slidably installed in a guide rail. The guide rail is fixed to the housing. A number of cleaning brushes that fit the surface of the fins are fixed inside the cleaning ring.

[0011] Preferably, a number of exhaust holes are opened at the bottom of the inner cavity.

[0012] Preferably, an air vent groove is opened in the air guide head. The air vent groove communicates with the hose. To block dust in the external air flow, a filter plate is fixedly installed in the air vent groove. A baffle is hingedly connected to one side of the air guide head through a hinge. The baffle is used to close the air vent groove. A torsion spring is installed in the hinge. A guide bar is fixed on the top of the air guide head. A guide block is slidably installed in the guide bar. A thin plate is fixedly arranged on the guide block. One end of a rope is fixedly connected to the thin plate. The other end of the rope is fixed to the baffle. A guide seat is fixed on the air guide head to guide the rope.

[0013] Preferably, a brush is fixed to the bottom of the baffle.

[0014] In summary, the present invention has the following beneficial effects:

[0015] 1. In this application, an air guide assembly is installed on one side of the housing. The air guide assembly includes an air guide pipe assembly fixedly communicating with the inner cavity and an air guide head at one end of the air guide pipe assembly. The air guide head is installed outside a new energy vehicle / drone and communicates with the external space. The air flow of the new energy vehicle / drone will be introduced into the air guide pipe assembly through the air guide head to dissipate heat from the motor.

[0016] 2. The air guide pipe assembly includes a pair of fixing plates fixed to the housing. A shunt pipe is fixedly installed between the two fixing plates. One end of the shunt pipe is fixedly connected to a joint. The other end of the shunt pipe is fixedly connected to at least one shunt nozzle. The end of the shunt nozzle is located inside the inner cavity and is fixedly connected to a diffuser nozzle. A hose is fixedly installed on the joint. The hose is fixedly connected to the air guide head. The air flow introduced by the air guide head enters the shunt pipe through the hose, and then is distributed to each shunt nozzle through the shunt pipe and ejected. Under the action of the diffuser nozzle at the end of the shunt nozzle, the air flow introduced at the air guide head is evenly dispersed, thus greatly increasing the heat dissipation area.

[0017] 3. The diffuser nozzle is composed of a base and a diffuser head. The base is fixedly connected to the diffuser head. One end of the base is fixedly connected to the shunt nozzle, and this end is designed in a conical shape, the purpose of which is to expand the divergence area of the air flow. The side of the diffuser head close to the base is designed in a concave shape. In this way, when the air flow hits the concave surface of the diffuser head, it will be evenly dispersed. Coupled with a number of diffusion holes opened on the diffuser head, the air flow is further dispersed, so that the action range of the air flow is greatly increased, effectively increasing the heat dissipation area.

[0018] 4. A number of air guide plates are fixedly installed at the top of the inner cavity. Each air guide plate is arranged in a stepped manner, and there is an arc surface on the side of each air guide plate facing the air duct assembly for changing the direction of the air flow. When the air flow hits the arc surface of the air guide plate, it will change from being parallel to the fins to being perpendicular to the fins, thereby dissipating heat from the fins in the vertical direction. Due to the stepped arrangement of each air guide plate, the air flow can dissipate heat from all parts of the fins, basically achieving full coverage of the fin part, thus greatly enhancing the heat dissipation effect.

[0019] 5. A cleaning ring is installed outside the motor. Connecting pieces are fixed at both ends of the cleaning ring. One end of the connecting piece is fixed on the slider, and the slider is slidably installed in the guide rail. The guide rail is fixed to the housing. A number of cleaning brushes that fit the surface of the fins are fixed inside the cleaning ring. During the operation of the new energy vehicle / drone, the situation of accelerating or braking will cause the slider to move along the guide rail under the action of inertia. As the slider moves, the cleaning brushes will sweep away the dust accumulated on the surface of the fins, ensuring the cleanliness of the fin surface to achieve a good working state.

Detailed implementation manners

[0029] Combined with the attached Figures 1-7 For the described motor heat dissipation outer shell structure, it includes an outer shell 11. A number of mounting feet 12 are fixed on the outer shell 11. The outer shell 11 is fixedly installed inside a new energy vehicle / drone through the mounting feet 12. An inner cavity 27 is opened inside the outer shell 11. At least one fixing seat 30 is fixed inside the inner cavity 27. The fixing seat 30 is fixed to the motor feet 29 on the motor 28, thereby fixedly installing the motor 28 inside the inner cavity 27. The motor 28 has fins 35 for heat dissipation:

[0030] During the long-term use of the motor 28 in a new energy vehicle / drone, heat dissipation is often relatively poor because the air circulation inside the new energy vehicle / drone is relatively poor. The applicant thought that during the operation of the new energy vehicle / drone, there will be a relatively large air flow outside. Based on this, the applicant considered introducing the air flow into the inner cavity 27 to dissipate heat for the motor 28. Specifically:

[0031] An air guide assembly 50 is added on one side of the outer shell 11. The air guide assembly 50 includes an air guide pipe assembly fixedly communicating with the inner cavity 27 and an air guide head 19 at one end of the air guide pipe assembly. The air guide head 19 is installed outside the new energy vehicle / drone and communicates with the outside space. The air flow of the new energy vehicle / drone will be introduced into the air guide pipe assembly through the air guide head 19 to dissipate heat for the motor 28;

[0032] To optimize the heat dissipation effect, the air guide pipe assembly is further improved. The purpose of this improvement is to disperse the introduced air flow and expand the heat dissipation area. The specific optimization is as follows:

[0033] The air duct assembly includes a pair of fixing pieces 13 fixed to the housing 11. A shunt pipe 15 is fixedly installed between the two fixing pieces 13. One end of the shunt pipe 15 is fixedly connected to a joint 16, and the other end of the shunt pipe 15 is fixedly connected to at least one shunt nozzle 14. The end of the shunt nozzle 14 is located in the inner cavity 27 and is fixedly connected to a diffuser nozzle. A hose 17 is fixedly installed on the joint 16. The hose 17 is fixedly connected to the air guide head 19. The air flow introduced by the air guide head 19 enters the shunt pipe 15 through the hose 17, and then is distributed to each shunt nozzle 14 through the shunt pipe 15 and ejected. Under the action of the diffuser nozzle at the end of the shunt nozzle 14, the air flow introduced at the air guide head 19 is evenly dispersed, thus greatly increasing the heat dissipation area;

[0034] The diffuser nozzle is composed of a base 37 and a diffuser head 36. The base 37 is fixedly connected to the diffuser head 36. One end of the base 37 is fixedly connected to the shunt nozzle 14, and this end is designed in a conical shape to expand the divergence area of the air flow. The side of the diffuser head 36 close to the base 37 is designed in a concave shape. In this way, when the air flow hits the concave surface of the diffuser head 36, it will be evenly dispersed. Coupled with a number of diffusion holes 38 opened on the diffuser head 36, the air flow is further dispersed, so that the action range of the air flow is greatly increased, effectively increasing the heat dissipation area.

[0035] Although the air flow introduced from the air duct assembly has been diffused in area, the air flow direction only acts on the fins 35 in the upper half part. The applicant hopes that it can act on more fins 35. For this reason, a number of air guide plates 31 are fixedly installed at the top of the inner cavity 27. Each air guide plate 31 is arranged in a stepped shape, and each air guide plate 31 has an arc surface on the side facing the air duct assembly for changing the direction of the air flow. The air guide plate 31 is located directly above the fins 35. When the air flow hits the arc surface of the air guide plate 31, it will change from parallel to the fins 35 to perpendicular to the fins 35, so as to dissipate heat from the fins 35 in the vertical direction. Due to the stepped arrangement of each air guide plate 31, the air flow can dissipate heat from each part of the fins 35, and basically can achieve full coverage of the fins 35 part, thus greatly enhancing the heat dissipation effect.

[0036] In addition, during long-term use, the applicant believes that dust will accumulate on the fin 35. Therefore, a cleaning ring 34 is installed outside the motor 28. Connectors 42 are fixed at both ends of the cleaning ring 34. One end of the connector 42 is fixed on the slider 40, and the slider 40 is slidably installed in the guide rail 39. The guide rail 39 is fixed to the housing 11. A number of cleaning brushes 41 that fit the surface of the fin 35 are fixed inside the cleaning ring 34. During the operation of the new energy vehicle / drone, acceleration or braking will cause the slider 40 to move along the guide rail 39 under the action of inertia. As the slider 40 moves, the cleaning brush 41 will sweep away the dust accumulated on the surface of the fin 35, ensuring the cleanliness of the surface of the fin 35 to achieve a good working state;

[0037] Furthermore, a number of exhaust holes 33 are opened at the bottom of the inner cavity 27. In cooperation with the vertical air flow guided by the air guide plate 31, the dust swept out by the cleaning brush 41 is discharged from the exhaust holes 33 to prevent secondary accumulation of dust.

[0038] During the common use of this application, dust is also likely to accumulate at the air guide head 19. Therefore, the applicant has further improved the air guide head 19:

[0039] An air vent groove 45 is opened in the air guide head 19, and the air vent groove 45 communicates with the hose 17. To block the dust in the external air flow, a filter plate 46 is fixedly installed in the air vent groove 45. A baffle 20 is hingedly connected to one side of the air guide head 19 through a hinge 44. The baffle 20 is used to close the air vent groove 45. When the new energy vehicle / drone is not moving, the baffle 20 closes the air vent groove 45 to prevent dust from entering; a torsion spring is installed in the hinge 44. A guide bar 22 is fixed on the top of the air guide head 19, and a guide block 23 is slidably installed in the guide bar 22. A thin plate 18 is fixedly arranged on the guide block 23, and one end of a rope 24 is fixedly connected to the thin plate 18. The other end of the rope 24 is fixed to the baffle 20. A guide seat 25 is fixed on the air guide head 19, and the guide seat 25 guides the rope 24. When the new energy vehicle / drone is moving, air flow is generated, which pushes the thin plate 18 and pulls the guide seat 25 to turn up the baffle 20. At this time, the baffle 20 no longer closes the air vent groove 45, and the generated air flow can enter the hose 17, and the torsion spring in the hinge 44 deforms;

[0040] Even further, a brush 21 is fixed at the bottom of the baffle 20. When the baffle 20 is turned up, the brush 21 can clean the surface of the filter plate 46 to prevent the filter plate 46 from being blocked and ensure good ventilation effect of the filter plate 46.

[0041] The above embodiments are only used to illustrate the technical concept and features of the present invention, and the purpose is to enable those skilled in the art to understand the content of the present invention and implement it, and it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
