[0018] 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.

[0019] Refer to the instruction manual Figure 1-7The present invention provides an integrated charging device using air conditioning refrigeration, including a charging device body 1 for charging an electric vehicle, wherein the charging device body 1 includes a front door 101, a front sealing plate 102, an AC installation disk 103, an AC / DC charging module 104, an upper isolation sealing plate 105, a cabinet 106, a control system installation disk 107, a rear sealing plate 108, a rear door 109 and two charging interfaces 1010; The front sealing plate 102, the AC installation plate 103, the AC / DC charging module 104, the upper isolation sealing plate 105, the control system installation plate 107 and the rear sealing plate 108 are all installed inside the cabinet 106, the front door 101 is installed on the front side of the cabinet 106, the rear door 109 is installed on the rear side of the cabinet 106, the AC installation plate 103 is arranged between the front sealing plate 102 and the rear sealing plate 108, and the front sealing plate 102 is arranged on the front side of the rear sealing plate 108, the AC / DC charging module 104 is arranged on the top of the AC installation plate 103, and the top of the front sealing plate 102 and the top of the rear sealing plate 108 are fixed to the bottom of the AC / DC charging module 104, the upper isolation sealing plate 105 is installed on the front side of the cabinet 106, and the rear door 109 is installed on the rear side of the cabinet 106. The sealing plate 105 is arranged on the top of the AC / DC charging module 104, and the two charging interfaces 1010 are respectively arranged on both sides of the cabinet 106. The air-conditioning and refrigeration device 2 is installed on the rear side of the rear sealing plate 108, and a cooling component for heat dissipation is installed on the rear side of the charging device body 1; the cooling component includes the air-conditioning and refrigeration device 2, and the air-conditioning and refrigeration device 2 is installed on the rear side of the charging device body 1, and a protective component for reducing dust adhesion is arranged on the outside of the air-conditioning and refrigeration device 2; a hot air duct 4 and a cold air duct 3 for guiding the circulation of hot air and cold air are arranged inside the charging device body 1, and the cold air duct 3 is arranged in front of the hot air duct 4, and the hot air duct 4 corresponds to the position of the air-conditioning and refrigeration device 2 in front and back.

[0020] First, fix the circuit board of the AC / DC charging module 104 inside the cabinet 106 according to the designed layout, and make corresponding electrical circuit connections to ensure that each charging interface 1010 is connected to the corresponding circuit on the circuit board. Next, install the compressor, condenser, throttling device such as electronic expansion valve, evaporator, etc. in the air-conditioning refrigeration device 2 to form a complete refrigeration cycle system, fix the compressor to a suitable position at the bottom of the charging device body 1 through a shock-absorbing rubber pad, install the condenser on the side or back of the charging device body 1 and other areas that are conducive to heat dissipation, and connect the corresponding refrigeration pipes to ensure that the pipes are well sealed. Then, install the evaporator near the AC / DC charging module 104 and around the charging interface 1010, ensuring that the evaporator's fins face the direction that is conducive to the flow of cold air. After that, arrange the air duct and install the fan so that the fan outlet is aligned with the air duct entrance to ensure that a complete and smooth cold air circulation path can be formed. At the same time, multiple high-precision temperature sensors are set at the AC / DC charging module 104, the charging interface 1010 and the internal pipes of the charging device body 1 to monitor the temperature of each part in real time and feed back the temperature data to the control system installed on the control system installation disk 107. It can also be equipped with wireless communication modules such as Wi-Fi, 4G, etc. to achieve communication connection with external devices such as user collection APP, charging pipeline platform, etc., so that users can remotely view the working status of the charging device. Finally, connect the temperature sensor, communication module and the signal lines of the compressor, fan and other controlled components to complete the overall assembly of the equipment and close the cabinet 106.

[0021] Afterwards, when the user connects the device to be charged to the corresponding charging interface 1010 of the charging device body 1, the AC / DC charging module 104 automatically detects the type, power and other information of the device to be charged, and then starts the charging process according to the preset charging protocol, and begins to output appropriate charging current and voltage to the device to be charged.

[0022] During the charging process, the temperature sensor inside the cabinet 106 collects temperature data of key parts in real time and transmits the data to the control system installed on the control system installation disk 107. The control system determines whether the current temperature exceeds the preset threshold. If it exceeds, the air conditioning refrigeration part is immediately started. According to the degree of temperature exceedance and charging power and other factors, the control algorithm adjusts the operating frequency of the compressor, the speed of the fan and other parameters to make the evaporator produce appropriate cooling capacity. The cold air circulates through the air duct to cool the inside of the charging device and the device to be charged. As the temperature drops, the control system continues to dynamically adjust the refrigeration parameters until the temperature stabilizes in a reasonable range, maintains stable refrigeration power operation, and ensures that the entire charging process is in a good temperature environment.

[0023] At the same time, in order to improve the user's operational convenience, users can pair and connect with the communication module of this charging device through the corresponding APP installed on external devices such as mobile phones. After successful connection, the device's charging progress, temperature of various parts and other working status information can be viewed in real time on the APP interface. In addition, users can remotely modify and adjust charging parameters such as charging current limit, charging mode, etc. and cooling parameters such as cooling temperature setting, cooling intensity adjustment, etc. on the APP according to actual needs, so as to conveniently and flexibly control the operation of the device.

[0024] In order to ensure the orderly flow of hot and cold air, it is necessary to guide and transport the flow of hot and cold air, such as Figure 7 As shown, the cold air duct 3 is arranged between the upper isolation sealing plate 105, the cabinet 106, the front door 101 and the front sealing plate 102, and the hot air duct 4 is arranged between the AC / DC charging module 104, the rear sealing plate 108 and the rear door 109. The cold air generated by the evaporator in the air-conditioning and refrigeration device 2 is guided by the cold air duct 3 formed by the upper isolation sealing plate 105, the cabinet 106, the front door 101 and the front sealing plate 102, and then the hot air in the AC / DC charging module 104 is guided to circulate through the hot air duct 4 formed by the AC / DC charging module 104, the rear sealing plate 108 and the rear door 109, and the cold air in the cold air duct 3 will pass through the AC / DC charging module 104, and the hot air therein will be blown into the interior of the air-conditioning and refrigeration device 2, so that it will pass through the compressor in the air-conditioning and refrigeration device 2 for another refrigeration cycle.

[0025] In order to reduce the disorder caused by charging, it is necessary to display the charging information to facilitate user selection, such as Figure 1 and 2 As shown, timers 5 are installed on both sides of the cabinet 106, and a display screen 6 for displaying the charging time is installed on the front side of the front door 101. When the user operates the charging device body 1 to charge the charging device, the timer 5 can be operated to time the charging time, and the charging time can be displayed by the display screen 6, so as to facilitate subsequent users to quickly judge the usage status of the charging device body 1, avoid wasting time due to blind searching, and arrange time reasonably to avoid disputes due to scrambling for the charging device body 1.

[0026] Among them, during the use of the air conditioning and refrigeration device 2, it is easy to be affected by external dust adhesion and affect the performance of the equipment, and it is also easy to be damaged by external collision. In this case, the air conditioning and refrigeration device 2 needs to be maintained, such as Figure 1 and 2As shown, the protective member includes a mesh cover 7, which is sleeved on the rear end of the air-conditioning and refrigeration device 2, and fixing plates 8 are installed on both sides of the front end of the mesh cover 7.

A fixing groove 11 is provided on the side where the two fixing columns 10 are close to each other, and the front end of the fixing column 10 is fixed together with the rear side of the rear door 109. The staff fits the mesh cover 7 on the air-conditioning and refrigeration device 2 through the engagement of the fixing holes 9 on the fixing plate 8 and the fixing columns 10, and blocks impurities such as dust through the mesh cover 7 to prevent dust and other impurities from entering the air-conditioning and refrigeration device 2 and affecting the performance of the air-conditioning and refrigeration device 2. At the same time, it can also prevent collisions from directly damaging the air-conditioning and refrigeration device 2, thereby ensuring the integrity of the air-conditioning and refrigeration device 2.

[0027] At the same time, in order to prevent dust and other impurities from adhering too much and clogging the mesh cover 7, it is necessary to maintain the mesh cover 7 in time, such as Figure 3 As shown, a plurality of wind speed sensors 18 are arranged inside the mesh cover 7, and the plurality of wind speed sensors 18 are spaced apart outside the air-conditioning and refrigeration device 2, a connecting column 19 is installed on the front side of the wind speed sensor 18, and the front end of the connecting column 19 is fixed together with the rear door 109; an alarm 20 for early warning is installed on the top of the cabinet 106, and the wind speed sensor 18 can monitor the air circulation inside the mesh cover 7 by virtue of the spaced apart distribution of the plurality of wind speed sensors 18. When the air circulation rate drops to the set value, it means that the ventilation effect of the mesh cover 7 is affected by dust and other debris. At this time, the control system activates the alarm 20 for early warning, and informs the staff to clean and maintain the mesh cover 7 in time to ensure the good operation of the air-conditioning and refrigeration device 2.

[0028] When cleaning, it is necessary to realize the convenient disassembly of the net cover 7 to reduce the burden of the staff in disassembling and assembling the net cover 7. Figure 3 and 4As shown, the fixing plate 8 is provided with a through hole 12 and two positioning holes 13 on the outside, the two positioning holes 13 are respectively at the top and bottom of the through hole 12, the ends of the two positioning holes 13 close to each other are connected with the through hole 12, and the ends of the two positioning holes 13 far away from each other are respectively connected with the two fixing holes 9, a threaded rod 14 is provided inside the through hole 12, and the two ends of the threaded rod 14 are both threadedly connected with positioning plates 15 on the outside, and the end of the positioning plate 15 away from the threaded rod 14 passes through the positioning hole 13 and extends to the inside of the fixing groove 11; two positioning seats 16 are provided between the two positioning plates 15, and the positioning seat 16 is movably sleeved on the outside of the threaded rod 14 through a bearing, and the positioning seat 1 6 is fixed to the inner wall of the through hole 12, and an adjusting wheel 17 is provided between the two positioning seats 16. The adjusting wheel 17 is sleeved on the outside of the threaded rod 14. The threaded rod 14 is driven to rotate by rotating the adjusting wheel 17, and the threaded rod 14 drives the two positioning plates 15 limited by the positioning holes 13 to move inward, so that the positioning plates 15 are separated from the fixing grooves 11 on the fixing column 10, so that it is convenient for the staff to remove the net cover 7 for cleaning and maintenance. At the same time, the threaded rod 14 can also be rotated to drive the two positioning plates 15 to move outward, so that the positioning plates 15 are embedded in the fixing grooves 11 on the fixing column 10, and the effect of limiting the net cover 7 is achieved by the engagement of the positioning plates 15 with the fixing grooves 11.

[0029] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
