[0012] In summary, the present invention has the following beneficial effects: 1. The present application adds an air guide assembly to one side of the outer shell. The air guide assembly includes an air guide tube assembly fixedly connected to the inner cavity and an air guide head at one end of the air guide tube assembly. The air guide head is installed on the outside of the new energy vehicle / UAV and connected to the external space. The airflow of the new energy vehicle / UAV will be introduced into the air guide tube assembly through the air guide head to dissipate the heat of the motor.

[0013] 2.

DETAILED DESCRIPTION

[0020] Combined with Figure 1-Figure 7 The motor heat dissipation housing structure includes a housing 11, a plurality of mounting feet 12 are fixed on the housing 11, the housing 11 is fixedly installed inside the new energy vehicle / unmanned aerial vehicle through the mounting feet 12, an inner cavity 27 is provided in the housing 11, at least one fixing seat 30 is fixed in the inner cavity 27, the fixing seat 30 is fixed to the motor foot 29 on the motor 28, so that the motor 28 is fixedly installed in the inner cavity 27, and the motor 28 has fins 35 for heat dissipation: During long-term use of the motor 28 in the new energy vehicle / drone, the heat dissipation is often poor because the air circulation inside the new energy vehicle / drone is relatively poor. The applicant thinks that during the operation of the new energy vehicle / drone, there will be a relatively large airflow outside. Based on this, the applicant considers introducing the airflow into the inner cavity 27 to dissipate the heat of the motor 28, specifically: An air guide assembly 50 is installed on one side of the housing 11. The air guide assembly 50 includes an air guide pipe assembly fixedly connected to 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 on the outside of the new energy vehicle / drone and connected to the external space. The airflow of the new energy vehicle / drone is introduced into the air guide pipe assembly through the air guide head 19 to dissipate heat for the motor 28. In order to optimize the heat dissipation effect, the air guide tube assembly is further improved. The purpose of this improvement is to disperse the introduced airflow and expand the heat dissipation area. The specific optimization is as follows: The air guide assembly includes a pair of fixing plates 13 fixed to the housing 11, a shunt pipe 15 is fixedly installed between the two fixing plates 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 diffusion nozzle, a hose 17 is fixedly installed on the joint 16, and the hose 17 is fixedly connected to the air guide head 19, the airflow introduced by the air guide head 19 enters the shunt pipe 15 through the hose 17, and then is distributed to each of the shunt nozzles 14 through the shunt pipe 15 for spraying, and under the action of the diffusion nozzle at the end of the shunt nozzle 14, the airflow introduced at the air guide head 19 is evenly dispersed, thereby greatly increasing the heat dissipation area; The diffuser nozzle is composed of a base 37 and a diffuser head 36, wherein the base 37 is fixedly connected to the diffuser head 36, one end of the base 37 is fixedly connected to the diverter nozzle 14, and this end is conical in design, the purpose of which is to expand the divergence area of ​​the airflow, and the side of the diffuser head 36 close to the base 37 is concave in design, so that the airflow will be evenly dispersed when it hits the concave surface of the diffuser head 36, and the plurality of diffuser holes 38 opened on the diffuser head 36 further disperse the airflow, thereby greatly increasing the range of action of the airflow and effectively increasing the heat dissipation area.

[0021] Although the airflow introduced from the air guide duct assembly is diffused in area, the airflow direction only acts on the upper half of the fins 35. The applicant hopes to act on more of the fins 35. To this end, a number of air guide plates 31 are fixedly installed on the top of the inner cavity 27. Each of the air guide plates 31 is arranged in a stepped manner, and each of the air guide plates 31 has an arc surface on the side facing the air guide duct assembly for changing the direction of the airflow. When the airflow hits the arc surface on the air guide plate 31, it will change from being parallel to the fins 35 to being perpendicular to the fins 35, thereby dissipating the heat in the vertical direction of the fins 35. Due to the stepped arrangement of each of the air guide plates 31, the airflow can dissipate heat for each part of the fins 35, and basically full coverage of the fins 35 can be achieved, thereby greatly enhancing the heat dissipation effect.

[0022] In addition, during long-term use, the applicant believes that dust will accumulate on the fins 35. For this reason, a cleaning ring 34 is installed on the outside of the motor 28. Connectors 42 are fixed at both ends of the cleaning ring 34. One end of the connecting member 42 is fixed on the slider 40. 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 are in contact with the surface of the fin 35 are fixed on the inside of 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. The cleaning brush 41 will sweep away the dust accumulated on the surface of the fin 35 as the slider 40 moves, ensuring that the surface of the fin 35 is clean to achieve a good working state. Furthermore, a plurality of exhaust holes 33 are provided at the bottom of the inner cavity 27 , and the dust swept out by the cleaning brush 41 is discharged from the exhaust holes 33 in cooperation with the vertical airflow guided by the air guide plate 31 , so as to prevent secondary accumulation of dust.

[0023] In the common use process of the present application, dust is easily accumulated at the air guide head 19. Therefore, the applicant has made further improvements to the air guide head 19: A ventilation groove 45 is provided in the air guide head 19, and the ventilation groove 45 is connected to the hose 17. In order to block dust in the external airflow, a filter plate 46 is fixedly installed in the ventilation 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 ventilation groove 45. When the new energy vehicle / drone is not moving, the baffle 20 closes the ventilation groove 45 to prevent dust from entering; a torsion spring is installed in the hinge 44, and a guide strip 22 is fixed on the top of the air guide head 19. A guide block 23 is slidably installed in the guide strip 22. A thin plate 18 is fixedly provided on the guide block 23, 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, and a guide seat 25 is fixed on the air guide head 19, the guide seat 25 guides the rope 24, when the new energy vehicle / unmanned aerial vehicle moves, an airflow is generated, the thin plate 18 is pushed, the guide seat 25 is pulled, and the baffle 20 is turned up, at this time, the baffle 20 no longer closes the ventilation groove 45, the generated airflow can enter the hose 17, and the torsion spring in the hinge 44 is deformed; Furthermore, a brush 21 is fixed at the bottom of the baffle 20 , and 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, thereby ensuring a good ventilation effect of the filter plate 46 .

[0024] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology in this field to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
