Figure 1 Figure 1

[0030] In an embodiment, the charging device 100 can include a housing 10 and a plurality of power supply modules 20.

[0034] In the embodiments of the present application, the fixing mode when fixedly installed and fixedly connected is not specifically limited. For example, the fixing mode can include, but is not limited to, welding fixation, bolt fixation, buckle fixation, etc.

[0035] Please refer to Figure 2 In some embodiments, the charging device 100 further comprises a heat dissipation mechanism 30. The heat dissipation mechanism 30 can comprise an air inlet piece 31, an air guide piece 32, a temperature detection piece 33 and a processor 34.

[0036] The air inlet piece 31 can be located between the air inlet 11 and the plurality of power modules 20 in the first direction. The air inlet piece 31 can be fixedly connected with the cabinet 10. The air inlet piece 31 can drive the airflow to flow from the air inlet 11 to at least the power modules 20, and make the airflow flow through at least part of the power modules 20 and then flow out of the cabinet 10 from the air outlet 12.

[0037] The number of the air guide pieces 32 can be multiple, and the multiple air guide pieces 32 are located between the air inlet piece 31 and the plurality of power modules 20 in the first direction. The number of the air guide pieces 32 can be greater than or equal to the number of the power modules 20, and each air guide piece 32 is correspondingly arranged with one power module 20. Each air guide piece 32 can comprise a first driving piece 321 and a plurality of air guide plates 322. The plurality of air guide plates 322 can be arranged at intervals in the second direction, and each air guide plate 322 is rotatably connected to the inner wall of the cabinet 10. The number of the first driving pieces 321 can be less than or equal to the number of the air guide plates 322, each first driving piece 321 is connected with the corresponding air guide plate 322, and the first driving piece 321 can drive the corresponding air guide plate 322 to rotate.

[0038] The number of temperature detecting members 33 can be multiple, and each temperature detecting member 33 corresponds to a power module 20 and is located on one side of the corresponding power module 20. Each temperature detecting member 33 can detect the temperature of the corresponding power module 20 and output corresponding temperature detection information. The processor 34 is connected to each temperature detecting member 33 and the first driving member 321 for communication. The processor 34 can receive the temperature detection information of all temperature detecting members 33 and determine the specific power module 20 to be started based on the received temperature detection information. The processor 34 can control the first driving member 321 to work, so that the first driving member 321 drives the corresponding air guide plate 322 to rotate, thereby guiding the airflow to the started power module 20.

[0039] It is understood that the rotatable connection can be achieved by a rotating connector, which is a connection method that allows the two components to rotate relative to each other. In the embodiments of the present application, there is no specific limitation on the type of rotating connector. For example, the rotating connector may include, but is not limited to, a bearing, a pin, a hinge, etc.

[0040] It is understood that the first driving member 321 can be an electric or pneumatic member with a rotational driving function. In the embodiments of the present application, the type of the first driving member 321 is not specifically limited. For example, the first driving member 321 can be, but is not limited to, a driving member that can directly drive an object to rotate, such as a motor or a rotary cylinder. For another example, the first driving member 321 can be, but is not limited to, a driving member that can directly drive an object to move linearly, such as a linear motor or a cylinder, and can be combined with a transmission structure such as a connecting rod structure or a gear rack structure to form an assembly.

[0041] Exemplarily, the plurality of air guides 32 may correspond one-to-one with the plurality of power modules 20. Each air guide 32 is provided with a first driving member 321, which can drive the corresponding plurality of air guides 322 to rotate synchronously. The plurality of air guides 322 may be connected via a transmission member, and the first driving member 321 connects to the transmission member and drives the transmission member to move, thereby driving the plurality of air guides 322 to rotate synchronously. The transmission member may be a synchronous belt and synchronous wheel structure, a gear rack structure, or a connecting rod structure.

[0042] It can be understood that when the first driving member 321 is a cylinder or a rotary cylinder, the solenoid valve provided on the first driving member 321 can be communicatively connected with the processor 34 , thereby realizing the communication connection between the first driving member 321 and the processor 34 .

[0043] In the embodiments of the present application, the communication connection method is not specifically limited. For example, the communication connection can be a wired communication connection implemented through a device such as a signal line. For another example, the communication connection can be a wireless communication connection implemented through technologies such as 3G, 4G, 5G, Bluetooth, and wireless local area network.

[0044] In embodiments of the present application, the type of the temperature detecting member 33 is not specifically limited. For example, the temperature detecting member 33 can be, but is not limited to, a temperature sensor, a thermistor, or the like.

[0045] In embodiments of the present application, the installation position of the temperature detecting member 33 is not specifically limited. For example, the temperature detecting member 33 can be fixedly connected to the inner wall of the casing 10. For another example, the temperature detecting member 33 can be fixedly connected to the corresponding power module 20.

[0046] In embodiments of the present application, the type of the processor 34 is not specifically limited. For example, the processor 34 can be a general central processing unit (CPU), a microprocessor, an application-specific integrated circuit (ASIC), or one or more integrated circuits for controlling the execution of the programs of the above solutions.

[0047] It can be understood that the processor 34 can determine the temperature of each power module 20 according to the received temperature detecting information. Since the power module 20 generates heat when working to charge the vehicle, the temperature of the started power module 20 is higher than that of the unstarted power module 20. The processor 34 can determine whether there is a power module 20 whose temperature exceeds a preset temperature threshold, and determine the started power module 20 whose temperature exceeds the temperature threshold when there is. Alternatively, the processor 34 can compare the temperatures of the plurality of power modules 20, and determine the started power module 20 whose temperature is higher. Then, the processor 34 can control the first driving member 321 in at least part of the air guiding member 32 to work according to the position of the started power module 20, so as to make the air guiding plate 322 in the corresponding air guiding member 32 face the started power module 20, so as to guide the air flow entering the casing 10 from the air inlet 11 to the started power module 20, increase the flow of the air flow flowing through the started power module 20, and enhance the air cooling effect of the started power module 20. The temperature threshold can be the temperature that the power module 20 can reach after working, and the specific value thereof can be adjusted according to the model of the power module 20, which is not limited in embodiments of the present application.

[0048] Meanwhile, the processor 34 can control the first driving member 321 to work according to a preset rule when determining which of the started power modules 20 are. In the embodiments of the present application, the specific content of the preset rule is not specifically limited. For example, the content of the preset rule can include that when the Nth and the N+1th power modules 20 from top to bottom in the M power modules 20 arranged in the second direction are started, all the air deflectors 322 corresponding to the power modules 20 above the Nth power module 20 rotate counterclockwise, all the air deflectors 322 corresponding to the power modules 20 below the N+1th power module 20 rotate clockwise, and the angle of rotation of each air deflector 322 is related to the order of the corresponding power module 20 in the plurality of power modules 20. Wherein, N is an integer greater than or equal to 1, and M is greater than N+1.

[0049] For example, as shown in FIG. 1, Figure 1 Figure 1 It is shown that three power modules 20 in the charging device 100 and three air deflecting members 32 corresponding to the three power modules 20, the three power modules 20 are ordered from top to bottom, and the three air deflecting members 32 are ordered from top to bottom. When the first power module 20 is started and the other two power modules 20 are not started, the plurality of air deflectors 322 in the first air deflecting member 32 can be rotated to be parallel to the first direction, guiding the airflow a to flow to the started power module 20 along the first direction. The plurality of air deflectors 322 in the second air deflecting member 32 and the third air deflecting member 32 can be rotated to a direction forming an acute angle with the first direction, respectively guiding the airflow b and the airflow c to flow to the started power module 20; wherein the angle between the air deflectors 322 in the second air deflecting member 32 and the first direction is smaller than the angle between the air deflectors 322 in the third air deflecting member 32 and the first direction.

[0050] In other embodiments, the heat dissipation mechanism 30 can not include the temperature detecting member 33. The processor 34 can be in communication connection with the plurality of power modules 20. The processor 34 can detect whether the power modules 20 are working, and control the first driving member 321 to work, so that the air deflector 322 corresponding to the first driving member 321 is directed to the started power module 20, so as to increase the flow of the airflow flowing through the started power module 20.

[0051] It can be understood that when the power module 20 is working, the voltage or current in part of the pins or circuits on the power module 20 will change. The processor 34 can monitor the voltage or current change in the corresponding pins or circuits to realize the monitoring of whether the power module 20 is started.

[0052] In some embodiments, the heat dissipation mechanism 30 can further include an air inlet louver 35, an air outlet member 36 and an air outlet louver 37. ​

[0053] The air inlet shutter 35 can be at least partially accommodated in the air inlet 11 and shield the air inlet 11. The air outlet shutter 37 can be at least partially accommodated in the air outlet 12 and shield the air outlet 12. The air inlet shutter 35 and the air outlet shutter 37 are fixedly connected with the cabinet 10.

[0054] The air outlet member 36 can be located between the air outlet 12 and the plurality of power modules 20 in the first direction. The air outlet member 36 can be fixedly connected with the cabinet 10. The air outlet member 36 can drive the airflow to flow from the power modules 20 to the air outlet 12. The air outlet member 36 cooperates with the air inlet member 31 to drive the airflow to flow from the air inlet 11 to the air outlet 12, and flow through at least part of the power modules 20, thereby achieving air cooling of the charging device 100.

[0055] It can be understood that the air inlet shutter 35 and the air outlet shutter 37 are each provided with a plurality of air inlets, and the airflow can enter the cabinet 10 through the air inlets of the air inlet shutter 35 and then flow out of the cabinet 10 through the air inlets of the air outlet shutter 37.

[0056] It can be understood that the air inlet member 31 and the air outlet member 36 can each be a component formed by a plurality of fans or a plurality of air blowers. The air inlet member 31 and the air outlet member 36 direct the airflow in the same direction.

[0057] In some embodiments, the air inlet shutter 35 includes a plurality of air inlet blades 351, and the air outlet shutter 37 includes a plurality of air outlet blades 371. The plurality of air inlet blades 351 are arranged at intervals in the second direction, and the gap spaces between the plurality of air inlet blades 351 form the air inlets of the air inlet shutter 35. The plurality of air outlet blades 371 are arranged at intervals in the second direction, and the gap spaces between the plurality of air outlet blades 371 form the air inlets of the air outlet shutter 37.

[0058] Each of the air inlet blades 351 and each of the air outlet blades 371 can maintain a shielding state. When the air inlet blade 351 maintains the shielding state, the air inlet blade 351 is arranged obliquely, and the distance between the top end of the air inlet blade 351 and the plurality of power modules 20 in the first direction is less than the distance between the bottom end of the air inlet blade 351 and the plurality of power modules 20 in the first direction. When the air outlet blade 371 maintains the shielding state, the air outlet blade 371 is arranged obliquely, and the distance between the top end of the air outlet blade 371 and the plurality of power modules 20 in the first direction is less than the distance between the bottom end of the air outlet blade 371 and the plurality of power modules 20 in the first direction.

[0059] It can be understood that when the air inlet blades 351 and the air outlet blades 371 are kept in the shielding state, the air inlet blades 351 and the air outlet blades 371 are kept inclined downward in the direction towards the outside of the casing 10, and the downward inclined air inlet blades 351 and the air outlet blades 371 can guide the rainwater to flow in the direction away from the casing 10 and in the downward direction after receiving the rainwater. In this way, the rainwater entering the charging device 100 through the air inlet louvers 35 and the air outlet louvers 37 in the rainy weather can be reduced, and the safety of the charging device 100 can be improved.

[0060] Please refer to Figure 3 In some other embodiments, the air outlet blades 371 can be kept in the shielding state. The air inlet louvers 35 can further include second driving members 352. The number of the second driving members 352 can be less than or equal to the number of the air inlet blades 351. Each of the air inlet blades 351 can correspond to one power module 20, so that each power module 20 can correspond to a plurality of adjacent air inlet blades 351. Each second driving member 352 can be connected with the corresponding air inlet blade 351 and drive the corresponding air inlet blade 351 to rotate. Each second driving member 352 is in communication connection with the processor 34.

[0061] The heat dissipation mechanism 30 can further include a rainwater detection member 38. The rainwater detection member 38 can be in communication connection with the processor 34. The rainwater detection member 38 can be located outside the casing 10 and fixedly connected with the casing 10. The rainwater detection member 38 can detect whether there is rain in the environment where the charging device 100 is located and output corresponding rainwater detection information to the processor 34. The processor 34 can determine whether there is rain in the environment where the charging device 100 is located according to the rainwater detection information. When the processor 34 determines that it is raining in the environment where the charging device 100 is located, the processor 34 can control each second driving member 352 to work, so that each air inlet louver 35 is rotated to the shielding state; when the processor 34 determines that it is not raining in the environment where the charging device 100 is located and there is a started power module 20 in the charging device 100, the processor 34 can control at least part of the second driving members 352 to work, so that the rotated air inlet louver 35 is rotated to face the started power module 20, thereby guiding the airflow to the started power module 20.

[0062] In the embodiments of the present application, the type of the rainwater detection member 38 is not specifically limited. For example, the rainwater detection member 38 can be, but is not limited to, a rainwater sensor, a water immersion sensor or the like which can directly detect whether there is rainwater. For another example, the rainwater detection member 38 can be a combination of a water collecting box and a liquid level sensor to determine whether it is raining by detecting the liquid level of the water collecting box.

[0063] It can be understood that the type of the second driving member 352 can be the same as that of the first driving member 321, which will not be described here again. It can be understood that the type of the second driving member 352 can be the same as that of the first driving member 321, which will not be described here again.

[0064] In the embodiments of the present application, the installation positions of the first driving member 321 and the second driving member 352 are not specifically limited. For example, the first driving member 321 and the second driving member 352 can be fixedly installed on the mounting frame fixedly connected with the inner wall of the cabinet 10, so as to realize the fixed connection with the cabinet 10.

[0065] It can be understood that when the processor 34 controls the second driving member 352 to work to set the plurality of air inlet blades 351 towards the started power module 20 to increase the flow smoothness and flow of the air flow flowing to the started power module 20 and to strengthen the heat dissipation effect of the started power module 20, the processor 34 can set the plurality of air deflectors 322 towards the started power module 20 at the same time when there is no rain and the power module 20 is started. The principle of the processor 34 controlling the second driving member 352 to work according to the rain detection information is the same as or similar to the principle of the processor 34 controlling the first driving member 321 to work according to the temperature detection information. The principle of the processor 34 determining whether it rains according to the rain detection information is the same as or similar to the principle of the processor 34 determining whether the power module 20 is started according to the temperature detection information, which will not be described here.

[0066] The heat dissipation mechanism 30 and the charging device 100 provided by the embodiments of the present application can increase the flow of the air flow flowing through the started power module 20 when the air inlet member 31 and the air outlet member 36 work, can strengthen the air cooling heat dissipation effect of the started power module 20, and can increase the service life of the charging device 100.

[0067] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application.
