DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example 1 See also Figure 1 to Figure 6 , a structural diagram of an over-temperature protection device for charging a new energy vehicle provided in Example 1 of the present invention, the over-temperature protection device for charging a new energy vehicle comprises: a charging device body 10, an air volume device 20 and a liquid cooling device 30; the air volume device 20 and the liquid cooling device 30 are installed on the charging device body 10.

[0025] The charging device body 10 includes a charging housing 101 and a charging body 102 disposed inside the charging housing 101 ; an exhaust port 103 is disposed on the top of the charging body 102 , and the exhaust port 103 is used to exhaust hot air.

[0026] The air volume device 20 includes a mounting sleeve 201, which is mounted on the mounting through hole 106 on the lower side wall of the charging housing 101; a driving motor 202 is mounted in the middle of the mounting sleeve 201, a transmission shaft 203 is arranged at the output end of the driving motor 202, and a plurality of elastic blades 204 are arranged in an array on the side wall of the transmission shaft 203; a filter assembly 206 is arranged at the inlet of the mounting sleeve 201; the filter assembly 206 is elastically mounted on the mounting sleeve 201 along the axial direction ...; the filter assembly 206 is elastically mounted on the mounting sleeve 201; the filter assembly 206 is elastically mounted on the mounting sleeve 201; the filter assembly 206 is elastically mounted on the mounting sleeve 201; the filter assembly 206 is elastically mounted on the mounting sleeve 201; the filter assembly 206 is elastically mounted on the mounting sleeve 201; the filter assembly 206 is elastically mounted on the mounting sleeve 201; the filter assembly A cleaning component is arranged on the filter component 206, and the cleaning component includes a mounting shaft 205, and a plurality of cleaning brushes 212 are arranged in an array on the outer side of the mounting shaft 205; a transmission mechanism is also arranged between the mounting shaft 205 and the transmission shaft 203, and the transmission structure is used to drive the mounting shaft 205 to rotate when the mounting shaft 205 is close to the transmission shaft 203; a rotating ring 216 is arranged in the middle position of the filter component 206, and a pressure ring 215 for squeezing the elastic blade 204 to deform is arranged on the rotating ring 216; the pressure ring 215 is arranged on the inlet side of the elastic blade 204.

[0027] Specifically, the present invention cools the charging device body 10 by providing an air volume device 20 and a liquid cooling device 30 to effectively prevent the charging device body 10 from overheating. The air volume device 20 drives the transmission shaft 203 to rotate by providing a driving motor 202, and the transmission shaft 203 drives the elastic blades 204 to rotate. The rotation of the elastic blades 204 provides power for air flow, and at the same time, the dust accumulation inside the charging housing 101 can be reduced by providing a filter assembly 206 to filter the air. After the filter assembly 206 has been used for a period of time, dust will accumulate on its surface and cannot meet the cooling requirements. Therefore, when the filter assembly 206 has a lot of dust on its surface, the air squeezes the filter assembly 206 more, causing the filter assembly 206 to approach the transmission shaft 203. At this time, under the action of the transmission structure, the installation shaft 205 drives the cleaning brush 212 to rotate to clean the dust on the surface of the filter assembly 206. At the same time, the pressure ring 215 approaches the elastic blade 204 and squeezes the elastic blade 204 away from the far end of the transmission shaft 203, so that the inclination angle of the elastic blade 204 becomes larger, so that the power of the elastic blade 204 to drive the air increases, so as to compensate for the loss of the filter assembly 206 being blocked and meet the cooling requirements of the charging body 102. The present invention can automatically clean the surface of the filter assembly 206 by setting a cleaning assembly and a transmission mechanism, avoiding the problem of manual cleaning required in the prior art. At the same time, the air volume device 20 is set below the side wall of the charging device body 10, so that the hot air inside the charging shell 101 can be quickly discharged. By providing a deformable elastic blade 204, when the filter assembly 206 is blocked, the pressure ring 215 squeezes the elastic blade 204, increasing the inclination angle of the transmission shaft 203, so that the power of the elastic blade 204 to drive the air is increased to compensate for the loss caused by the blockage of the filter assembly 206 and meet the cooling requirements of the charging body 102.

[0028] like Figure 2 and 3 As shown, in some embodiments, the transmission mechanism includes at least two first transmission rods 213 arranged on the mounting shaft 205 and at least two matching grooves 214 arranged on the transmission shaft 203, and the first transmission rod 213 is arranged at one end of the mounting shaft 205 close to the transmission shaft 203; the first transmission rod 213 is used to be inserted into the adjacent matching groove 214 when close to the transmission shaft 203, so that the transmission shaft 203 can drive the mounting shaft 205 to rotate.

[0029] In some embodiments, the filter assembly 206 includes an outer frame 207 and an intermediate sleeve 208; a filter screen 211 is disposed between the intermediate sleeve 208 and the outer frame 207, the filter screen 211 is an annular structure, and the inner ring is connected to the intermediate sleeve 208, and the outer ring of the filter screen 211 is connected to the inner ring of the outer frame 207; the mounting shaft 205 is rotatably mounted on the intermediate sleeve 208. The rotation of the mounting shaft 205 can drive the cleaning assembly to rotate, thereby cleaning the surface of the filter screen 211.

[0030] In some embodiments, the cleaning brush 212 is attached to the surface of the filter 211 .

[0031] like Figure 2-6 As shown, in other embodiments, the filter screen 211 will be deformed to a certain extent under the action of wind pressure, which makes it inconvenient for the cleaning brush 212 to clean the dust on its surface. Therefore, in order to solve this technical problem, the filter assembly 206 includes an outer frame 207, an intermediate sleeve 208 and an installation sleeve 209; a filter screen 211 is arranged between the intermediate sleeve 208 and the outer frame 207, and the filter screen 211 is an annular structure. The outer ring of the filter screen 211 is connected to the inner ring of the outer frame 207; the inner ring of the filter screen 211 is fixedly installed on the outside of the installation sleeve 209, and the installation shaft 205 is rotatably installed on the installation sleeve 209. At the center position of the mounting sleeve 209, the mounting shaft 205 passes through the center hole of the intermediate sleeve 208, the mounting sleeve 209 abuts against the intermediate sleeve 208, and the mounting sleeve 209 is connected to the intermediate sleeve 208 through a plurality of first elastic members 210; a mounting plate 218 is installed at one end of the mounting shaft 205 close to the transmission shaft 203, and the first transmission rod 213 is installed on the mounting plate 218; an energy storage mechanism is arranged between the mounting plate 218 and the mounting shaft 205, and the energy storage mechanism is used to drive the mounting shaft 205 and the mounting rod 220 to move away from each other when the first transmission rod 213 abuts against the matching groove 214. Specifically, when the filter screen 211 is blocked, the first transmission rod 213 is pushed by the installation shaft 205 to approach the transmission shaft 203, so that the first transmission rod 213 is inserted into the adjacent matching groove 214. The matching groove 214 drives the first transmission rod 213 to drive the installation disk 218 to rotate, and the installation shaft 205 is moved away from the installation disk 218 under the action of the energy storage mechanism. In this way, the installation shaft 205 drives the middle position of the installation sleeve 209 and the filter screen 211 to extend outward, so that the filter screen 211 is in a stretched state. In this way, the cleaning brush 212 can be aligned and cleaned when the filter screen 211 is in a stretched state to ensure the cleaning effect.

[0032] In some embodiments, the energy storage mechanism includes a mounting rod 220 fixedly mounted on a mounting plate 218, a second transmission rod 223 symmetrically arranged on both sides of the mounting rod 220, and two mating protrusions 219 arranged inside the mounting shaft 205, wherein the mating protrusions 219 are symmetrically arranged in the mounting shaft 205, and the mating protrusions 219 are arranged on the trajectory of the second transmission rod 223; an energy storage component 222 is sleeved on the outer side of the mounting rod 220, and the two ends of the energy storage component 222 are respectively fixedly mounted on a transmission sleeve 221 and the mounting rod 220, and the transmission sleeve 221 is sleeved on the outer side of the mounting rod 220, and the transmission sleeve 221 slides axially along the mounting shaft 205. In this way, when the first transmission rod 213 initially contacts the mating groove 214, the second transmission rod 223 rotates along with the mounting rod 220 under the drive of the mating groove 214. When the second transmission rod 223 passes through the mating protrusion 219, it drives the mounting shaft 205 away from the mounting disk 218. When the mounting rod 220 rotates to the maximum position relative to the mounting shaft 205 under the restriction of the energy storage member 222, the mounting shaft 205 is driven to rotate together, so that the cleaning brush 212 on the mounting shaft 205 cleans the surface of the filter screen 211.

[0033] In some embodiments, the energy storage member 222 may be a torsion spring, and the mating protrusion 219 may be an arc-shaped slope, so that the second transmission rod 223 can slide against the mating protrusion 219 .

[0034] In some embodiments, two sliding keys are symmetrically arranged on the outer side of the transmission sleeve 221, and the sliding keys are slidably arranged up and down in the sliding groove on the inner side wall of the installation shaft 205. The sliding groove is a strip structure, and the two sliding grooves are symmetrically arranged on the inner side of the installation shaft 205.

[0035] In some embodiments, the elastic blade 204 may be made of elastic plastic, so that when the pressure ring 215 presses it, it can be deformed, so that the inclination angle of the elastic blade 204 increases.

[0036] In some embodiments, the pressure ring 215 is connected to the rotating ring 216 via a support rod, and the rotating ring 216 is rotatably mounted on the intermediate sleeve 208 .

[0037] In some embodiments, the outer frame 207 is radially mounted with a plurality of elastic telescopic rods, and one end of the elastic telescopic rods away from the outer frame 207 is fixedly mounted on the mounting sleeve 201, thereby achieving the outer frame 207 being elastically mounted on the mounting sleeve 201 along the axial direction.

[0038] In some embodiments, the liquid cooling device 30 includes a liquid cooling housing 301 fixedly mounted on the side wall of the charging device body 10. A water tank 302 is disposed inside the liquid cooling housing 301, and a circulating pump 303 is disposed on the water tank 302. The input end of the circulating pump 303 is connected to the inside of the water tank 302, and the output end of the circulating pump 303 is connected to the input end of a condenser 304. The condenser 304 is disposed inside the charging body 102, and the output end of the condenser 304 is connected to the upper end of the water tank 302. In this way, when the circulating pump 303 works, the cooling medium in the water tank 302 is transported to the condenser 304 to cool the internal equipment of the charging body 102.

[0039] In some embodiments, a temperature sensor 105 is also provided on the charging body 102, and a controller is also provided on the charging device body 10. The temperature sensor 105, the transmission shaft 203 and the circulation pump 303 are all connected to the controller for communication. When the temperature sensor 105 reaches a first threshold, the controller controls the transmission shaft 203 to be powered on for primary cooling. When the temperature sensor 105 reaches a second threshold, the controller controls the circulation pump 303 to be powered on for cooling the charging body 102. At this time, the transmission shaft 203 is also powered on, so that the charging body 102 can be cooled quickly.

[0040] In some embodiments, a rain cover 104 is further disposed on the top of the charging housing 101 , and the rain cover 104 is disposed on the top of the exhaust port 103 .

[0041] like Figure 1 As shown, in some embodiments, a protective cover 217 is further provided at the entrance of the installation sleeve 201 to improve safety.

[0042] The working principle of the present invention is: When in use, when the air volume device 20 is in cooling operation, when the filter screen 211 is blocked, the first transmission rod 213 is pushed by the installation shaft 205 to approach the transmission shaft 203, so that the first transmission rod 213 is inserted into the adjacent matching groove 214, and the matching groove 214 drives the first transmission rod 213 to drive the installation disk 218 to rotate. Under the drive of the matching groove 214, the second transmission rod 223 follows the installation rod 220 to rotate. When the second transmission rod 223 passes through the matching protrusion 219, it drives the installation shaft 205 away from the installation disk 218, so that the installation shaft 205 drives the middle position of the installation sleeve 209 and the filter screen 211 to extend outward, so that the filter screen 211 is in a stretched state, so that the cleaning brush 212 can be aligned and cleaned in the stretched state of the filter screen 211 to ensure the cleaning effect; when the installation rod 220 is restricted by the energy storage member 222, the installation rod 220 rotates to the maximum position relative to the installation shaft 205, thereby driving the installation shaft 205 to rotate together, Then, the cleaning brush 212 installed on the rotating shaft 205 cleans the surface of the filter 211. By providing the deformable elastic blade 204, when the filter assembly 206 is blocked, the pressure ring 215 squeezes the elastic blade 204, increases the inclination angle of the transmission shaft 203, and increases the power of the elastic blade 204 to drive the air, so as to compensate for the loss caused by the blockage of the filter assembly 206 and meet the cooling requirements of the charging body 102.
