[0002] The motors of new energy vehicles will generate a lot of heat during operation. If it is not dissipated in time, it will seriously affect the performance and life of the motor. Therefore, an efficient heat dissipation structure is crucial. Its heat dissipation structure often combines multiple heat dissipation methods, such as water cooling, which arranges coolant channels in the motor casing and uses coolant circulation to take away heat. It has high heat dissipation efficiency and can accurately control the temperature. Air cooling uses fans or natural wind when the vehicle is driving to promote air flow and heat dissipation. It has a simple structure and low cost.

[0031] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the present invention relates to a heat dissipation structure of a motor housing of a new energy vehicle, comprising two housings 1, the two housings 1 are fixedly connected by a first bolt, one of the housings 1 is symmetrically structured and fixedly connected with two temperature sensors 101, it is worth noting that the temperature sensor 101 is an infrared temperature sensor of the prior art, in use, by detecting the temperature on both sides of the motor 2 inside the housing 1, and driving the two second pneumatic sliders 304 through the information terminal, so that it can achieve accurate local cooling treatment, and comprehensive covering cooling treatment, to achieve precise temperature control treatment, the two housings 1 are commonly fixedly sleeved with the motor 2, it is worth noting that when installing the motor 2, a waterproof coating needs to be arranged on the surface of the motor 2 to prevent the humidity inside the housing 1 from being high and affecting the service life of the motor 2, one of the housings 1 is arranged with a water cooling mechanism 3; The water cooling mechanism 3 includes two first slide rails 301 and a splash-proof assembly 4; the two first slide rails 301 are fixedly connected to the inner walls of both sides of one of the shells 1, and the splash-proof assembly 4 is arranged inside the other shell 1; The two first slide rails 301 are movably connected to the two second slide rails 303 through a plurality of first pneumatic sliders 302, and the first pneumatic sliders 302 are movably sleeved on the side surfaces of the first slide rails 301, and the side surfaces of the two second slide rails 303 are respectively movably sleeved with two second pneumatic sliders 304, and a plurality of support blocks 305 are respectively arranged on the tops of the two second pneumatic sliders 304, and one of the end support blocks 305 is fixedly connected to the second pneumatic slider 304, and two adjacent support blocks 305 are movably connected through a hinge chain 306, and the opposite sides of the two end support blocks 305 are fixedly connected to a retracting winch 307 through an extension module 5, and a support module 6 is arranged at the bottom of the retracting winch 307, and a plurality of atomizing nozzles 308 are fixedly sleeved in the upper holes of each support block 305. It is worth noting that when the plurality of atomizing nozzles 308 are arranged in a linear array, Figure 1The spray direction of the atomizing nozzle 308 is upward and backward, so as to avoid the contact between the atomized water droplets sprayed by the atomizing nozzle 308 and the motor 2, which will affect the installation environment of the motor 2. A reflux module 7 is arranged at the bottom of several atomizing nozzles 308, and the reflux module 7 is fixed at the bottom of one of the shells 1. The water cooling mechanism 3 of the present invention is uniquely designed to realize the two use states of linear array and circular arrangement of the atomizing nozzles 308; when the nozzles are arranged in a circular manner, the local area can be evenly cooled, and the consistency of local temperature can be effectively ensured; when the nozzles are arranged in a linear array, the pneumatic slider can not only realize local heat dissipation, but also significantly reduce the temperature difference on both sides of the shell 1, and optimize the internal temperature field; on the basis of the linear array of nozzles, the two groups of nozzles are moved to both sides by the extension module 5 to achieve symmetrical liquid cooling and heat dissipation, accurately dissipate heat for key parts, and improve heat dissipation efficiency; when the telescopic rod in the extension module 5 is fully stretched, the two groups of nozzles are tilted with the retracting winch 307 as the midpoint to achieve multi-angle heat dissipation coverage, comprehensively eliminate heat dissipation dead corners, and further In order to further enhance the heat dissipation effect, the present invention provides a reliable heat dissipation guarantee for the stable operation of the motor by means of two nozzle layout modes. The first pneumatic slider 302 is moved on the first slide rail 301 through the pneumatic system, and the heat dissipation treatment can be performed at close range and at long distance. Among them, the heat dissipation treatment at close range can improve the heat dissipation efficiency and reduce the local accumulation of heat. At the same time, the temperature distribution around the heat source is made more uniform. The heat dissipation treatment at long distance can prevent the atomized water droplets from entering the groove for installing the motor 2, thereby ensuring a dry working environment for the motor 2. When the atomizing nozzles 308 are arranged in a ring for heat dissipation treatment, the two first pneumatic sliders 302 are relatively moved on the first slide rail 301 through the pneumatic system, and the two end support blocks 305 apply torque to the retracting capstan 307, so that the several support blocks 305 are arranged in a ring on the retracting capstan 307, and the micro water pump 701 is operated to make the atomized water droplets spray out from the atomizing nozzle 308, so that the local area is heat-dissipated and the surrounding area can be evenly heat-dissipated at the same time.

[0032] In an embodiment of the present invention, Figure 5 As shown in the figure, the extension module 5 includes two first telescopic rods 501, and the two first telescopic rods 501 are fixedly connected to the side surface of the winding winch 307 in a symmetrical structure, and the two first telescopic rods 501 are respectively fixedly connected to the end support block 305, and the side surfaces of the two first telescopic rods 501 are respectively movably sleeved with first tension springs 502, and the two ends of the first tension springs 502 are respectively fixedly connected to the winding winch 307 and the end support block 305.

[0033] In an embodiment of the present invention, Figure 3 and Figure 6As shown, the support module 6 includes an airbag 601, and the airbag 601 is rotatably connected to the bottom of the winch 307. It is worth noting that the side surface of the airbag 601 is arranged with guide grooves in a linear array. When the airbag 601 is compressed, the airbag 601 can be compressed in an orderly manner into a disc shape to prevent the airbag 601 from being irregularly shaped when compressed, resulting in the bottom surface of the compressed airbag 601 contacting the upper surface of the second slide rail 303, causing wear on the side surface of the airbag 601 and reducing its service life. The bottom of the airbag 601 is movably connected with a plurality of balls 602 in an annular array, and the balls 602 roll and contact the bottom inner wall of one of the shells 1, and the top of the other shell 1 is fixedly connected with a micro air pump 603. It is worth noting that by using a micro The air pump 603 is relatively small in size and fits in with the hole on the top shell 1, effectively reducing the size of the device and facilitating its adaptation to new energy vehicles. The output end of the micro air pump 603 is fixedly connected with an air pipe 604, and the air pipe 604 is fixedly connected with the air bag 601. It is worth noting that the air pipe 604 has a telescopic function to prevent the air pipe 604 from breaking due to the force exerted on the air pipe 604 by the moving parts in the water cooling mechanism 3 during use, thereby affecting the service life of the device. The present invention sets a support module 6, which is filled with gas. The air bag 601 can support the windlass 307. When the gas is extracted, the air bag 601 is compressed into a pancake shape, leaving a large space between the lower surface of the air bag 601 and the driving component to avoid The non-driving parts move, and the squeezing force is applied to the airbag 601, causing the surface of the airbag to be damaged and reducing its service life. When the atomizing nozzles 308 are arranged in a ring, in order to prevent the airbag 601 from being squeezed by the two second slide rails 303 gathering in the middle, affecting the normal use of the airbag 601, the micro air pump 603 can be operated through an external control system, and the gas inside the airbag 601 is extracted, so that the airbag 601 is compressed in an orderly manner into a pancake shape, and a gap is left between the lower surface of the compressed airbag 601 and the second slide rail 303. When the two temperature sensors 101 simultaneously monitor a high temperature, the two second pneumatic sliders 304 are moved to both sides through the second slide rail 303 through the pneumatic system. At this time, through the first extension The retracted rod 501 separates the two end support blocks 305 from the retracting winch 307 and moves to both sides. The atomized water droplets are sprayed by the atomizing nozzle 308 to dissipate heat on both sides of the interior of the shell 1, thereby achieving a symmetrical liquid cooling heat dissipation treatment effect. When the first telescopic rod 501 is fully extended, the second pneumatic slider 304 continues to move, and the ball 602 slides on the inner wall of the bottom of one of the shells 1, while supporting the retracting winch 307 and displacing, so that the two groups of linearly arranged support blocks 305 are in an inclined state, and the interior of the shell 1 is heat-dissipated, thereby achieving a multi-angle heat dissipation coverage treatment effect inside the shell 1. In the liquid cooling heat dissipation, the water droplets flow into the water storage tank 703 through the through hole 704 to be used for the next heat dissipation treatment.

[0034] In an embodiment of the present invention, Figure 7 and Figure 8 As shown, the reflux module 7 includes a micro water pump 701, which is fixedly connected to the bottom of another shell 1 through a first bracket, and the output end of the micro water pump 701 is fixedly connected with a shunt pipe 702, and the shunt pipe 702 passes through one of the shells 1, and the shunt pipe 702 is fixedly connected to the atomizing nozzle 308, and one end of the shell 1 is fixedly connected with a water storage tank 703, and the water storage tank 703 is fixedly connected to the input end of the micro water pump 701, and a plurality of through holes 704 are opened in a linear array on the inner wall of one side of one shell 1, and the through holes 704 are fixedly connected with the water storage tank 703. During installation, according to Figure 1 As shown in the figure, the internal installation of the new energy vehicle is performed. When the motor 2 is used for a long time, its internal temperature is monitored by the temperature sensors 101 on both sides. When one of the temperature sensors 101 monitors a higher temperature, the two second pneumatic sliders 304 are moved on the second slide rails 303 through the external pneumatic system, so that the multiple atomizing nozzles 308 move toward the temperature sensor 101 with a higher monitoring temperature. Then, the micro water pump 701 is operated through the control system, and the water flows through the diverter pipe 702 and is sprayed from the atomizing nozzle 308 to form atomized water droplets, so as to cool the inside of the shell 1.

[0035] In an embodiment of the present invention, Figure 3 , Figure 5 , Fig. 9 and Fig.10As shown, the splash-proof assembly 4 includes a track 401, which is fixedly connected to the top inner wall of another shell 1, and a movable block 402 is movably connected to the bottom of the track 401. The bottom of the movable block 402 is movably connected to a transmission disk 403 through a first plug rod. The bottom of the transmission disk 403 is fixedly connected to four first magnets 404 in an annular array, and the top of the windlass 307 is fixedly connected to four second magnets 405 in an annular array, and the positions of the first magnets 404 and the second magnets 405 correspond to each other. A plurality of baffles 406 are movably sleeved on the side surface of the first plug rod, and the two end baffles 406 are respectively connected to the movable block 402 and the transmission disk 403. The moving disk 403 is fixedly connected, and several baffles 406 are tightly stacked. It is worth mentioning that a slider is arranged on the top of the baffle 406, and a slide groove is arranged on the bottom. Two adjacent baffles 406 are slidably connected inside the slide groove through the slider. The component has a fan-bone structure. When the atomizing nozzles 308 are arranged in a circular array, the several baffles 406 are rotated and arranged in a fan shape through magnetic attraction to block the atomized water droplets sprayed toward the motor 2 by the atomizing nozzle 308, so as to avoid the installation environment of the motor 2 being affected, causing the motor to be damp and reducing the service life. When the atomizing nozzles 308 are arranged in a ring, in order to prevent the atomized water droplets from being sprayed on the motor 2, the capstan 307 is rotated, and the magnetic attraction reaction between the first magnet 404 and the second magnet 405 drives the transmission disk 403 to rotate. The transmission disk 403 drives one of the end baffles 406, so that the several baffles 406 are supported and arranged in a fan shape to block the atomized water droplets sprayed toward the motor 2, so as to avoid the motor 2 from being reduced in service life due to the humid environment.

[0036] Working principle: This embodiment provides a heat dissipation structure for the motor housing of a new energy vehicle. During installation, Figure 1As shown, the internal installation of the new energy vehicle is performed. When the motor 2 is used for a long time, its internal temperature is monitored by the temperature sensors 101 on both sides. When one of the temperature sensors 101 monitors a higher temperature, the two second pneumatic sliders 304 are first moved on the second slide rail 303 through the external pneumatic system, so that the plurality of atomizing nozzles 308 move toward the temperature sensor 101 with a higher monitoring temperature. Then, the micro water pump 701 is operated through the control system, and the water flows through the shunt pipe 702 and is sprayed from the atomizing nozzle 308 to form atomized water droplets, so as to cool the inside of the shell 1. The first pneumatic slider 302 is moved on the first slide rail 301 through the pneumatic system, and the heat dissipation treatment can be performed at a short distance and a long distance. Among them, the heat dissipation treatment at a short distance, It can improve the heat dissipation efficiency, reduce the local accumulation of heat, and at the same time, make the temperature distribution around the heat source more uniform. The long-distance heat dissipation treatment can prevent the atomized water droplets from entering the groove where the motor 2 is installed, and ensure the dry working environment of the motor 2. When the atomizing nozzle 308 is arranged in a ring for heat dissipation treatment, the two first pneumatic sliders 302 are relatively moved on the first slide rail 301 through the pneumatic system, and the two end support blocks 305 apply torque to the retracting capstan 307, so that the plurality of support blocks 305 are arranged in a ring on the retracting capstan 307, and the micro water pump 701 works to make the atomized water droplets spray out from the atomizing nozzle 308. While the local area is heat-dissipated, uniform heat dissipation treatment can be achieved for the surrounding area. When the atomizing nozzle 308 is arranged in a ring, in order to prevent the atomized water droplets from being sprayed on the motor 2 When the capstan 307 rotates, the magnetic attraction reaction between the first magnet 404 and the second magnet 405 drives the transmission plate 403 to rotate, and the transmission plate 403 drives one of the end baffles 406, so that the baffles 406 are supported and arranged in a fan shape to block the atomized water droplets sprayed toward the motor 2, thereby preventing the motor 2 from being reduced in service life due to the humid environment. At the same time, when the atomizing nozzles 308 are arranged in a ring shape, in order to prevent the airbag 601 from being squeezed by the two second slide rails 303 gathering in the middle and affecting the normal use of the airbag 601, the micro air pump 603 can be operated through an external control system, and the gas inside the airbag 601 is extracted, so that the airbag 601 is orderly compressed into a pancake shape, and the compressed gas There is a gap between the lower surface of the capsule 601 and the second slide rail 303. When the two temperature sensors 101 monitor a high temperature at the same time, the two second pneumatic sliders 304 are moved to both sides through the second slide rails 303 through the pneumatic system. At this time, the two end support blocks 305 are separated from the windlass 307 through the first telescopic rod 501 and move to both sides. The atomized water droplets are sprayed by the atomizing nozzle 308 to dissipate heat on both sides of the shell 1 to achieve a symmetrical liquid cooling heat dissipation effect. When the first telescopic rod 501 is fully extended, the second pneumatic slider 304 continues to move, and the ball 602 slides on the inner wall of the bottom of one of the shells 1, while supporting the windlass 307 and displacing.The two groups of linearly arranged support blocks 305 are tilted to perform heat dissipation treatment inside the housing 1, achieving a multi-angle heat dissipation coverage treatment effect inside the housing 1. In liquid cooling, water drops flow into the water storage tank 703 through the through hole 704 to be used for the next heat dissipation treatment.
