[0028] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figures 1 to 4 The image shows a specific embodiment of a split-type charger according to this utility model. Figure 1 In one embodiment of the present invention, a split-type charger is shown, comprising: a main unit 100 including a main unit cabinet 110, one or more terminals 200 including terminal cabinets 210, and a gas transmission channel 300 connecting the main unit cabinet 110 and the terminal cabinets 210; the main unit cabinet 110 is provided with a first cavity 111 and a second cavity 112, and a first vent 113 and a second vent 114 located between the first cavity 111 and the second cavity 112; wherein the first vent 113 and the second vent 114 are... When the host 100 is in heating mode, vent 114 is set to the open state. The first cavity 111 and the second cavity 112 form an open heating air duct through the open first vent 113 and the second vent 114. The host cabinet 110 enters a semi-closed state when the heating air duct is open. The gas transmission channel 300 is opened when the terminal 200 is in heating mode, so that the air in the host cabinet 110 is input to the terminal cabinet 210 through the gas transmission channel 300. The terminal cabinet 210 enters a semi-closed state when the gas transmission channel 300 is open.

[0030] Specifically, such as Figure 2 and Figure 3As shown, the main unit 100 corresponding to the charger includes a main unit cabinet 110, which is used to house the working modules corresponding to the main unit 100. The terminal 200 corresponding to the charger is used to connect to the device to be charged. The working circuit corresponding to the terminal 200 is set inside the terminal cabinet 210. The main unit cabinet 110 has a first cavity 111 and a second cavity 112. A first vent 113 and a second vent 114 are provided between the first cavity 111 and the second cavity 112. When the main unit 100 is set to heating mode, the first vent 113 and the second vent 114 are set to open. At this time, the first cavity 111, the second cavity 112, the first vent 113 and the second vent 114 form an open heating air duct, that is, hot air flows along the heating air duct inside the main unit cabinet 110 to heat the working modules inside the main unit cabinet 110, so that the main unit 100 can complete the low-temperature start-up. Meanwhile, in order to ensure the speed of temperature rise inside the main unit cabinet 110, when the heating air duct is opened, the main unit cabinet 110 is set to a semi-closed state, so that the hot air inside the main unit cabinet 110 flows in a relatively closed space, reducing the impact of the low temperature outside air on the hot air inside the main unit cabinet 110.

[0031] When the ambient temperature corresponding to terminal 200 is too low and terminal 200 enters heating mode, the gas transmission channel 300 can be opened to transport hot air from the host cabinet 110 to the terminal cabinet 210. At this time, terminal cabinet 210 is also set to a semi-closed state to prolong the flow time of hot air inside terminal cabinet 210, so that the working circuit inside terminal cabinet 210 can heat up and start up more quickly.

[0032] When the host 100 and the terminal 200 enter the heating mode at the same time, both the host cabinet 110 and the terminal cabinet 210 are in a semi-closed state. This allows the host cabinet 110 to be filled with external air when the hot air from the host cabinet 110 flows to the terminal cabinet 210, while the excess air in the terminal cabinet 210 can be discharged to the outside, thus avoiding abnormal air pressure in the host cabinet 110 and the terminal cabinet 210.

[0033] When only terminal 200 is in heating mode, host 100 can understand that the current temperature meets the requirements, that is, the air temperature inside host cabinet 110 is in a relatively high state. Even if host cabinet 110 is in the open state, hot air with a higher temperature can still be input from host cabinet 110 to terminal cabinet 210 through gas transmission channel 300 to raise the temperature of terminal cabinet 210.

[0034] Furthermore, the number of terminals 200 corresponds one-to-one with the number of gas transmission channels 300. When there are multiple terminals 200, there are also multiple gas transmission channels 300. Additionally, the state of each gas transmission channel 300 is only related to its corresponding terminal 200. The closing or opening of one gas transmission channel 300 does not affect the opening or closing of other gas transmission channels 300.

[0035] In a specific embodiment, one or more temperature detection devices 400 can be installed on the inner and outer sides of the host cabinet 110 to detect the temperature status of the host 100, so that the host 100 can perform corresponding operations based on the temperature status. Alternatively, one or more temperature detection devices (not shown in the figure) can be installed on the inner and outer sides of the terminal cabinet 210 to detect the temperature status of the terminal 200, so that the terminal 200 can perform corresponding operations based on the temperature status.

[0036] like Figure 2 As shown, in one embodiment, the first vent 113 and the second vent 114 are respectively located on opposite sides of the adjacent surfaces of the first cavity 111 and the second cavity 112. The adjacent surfaces between the first cavity 111 and the second cavity 112 are also called the common surfaces, and both the first vent 113 and the second vent 114 are located on this common surface, communicating with both the first cavity 111 and the second cavity 112. The distance between the first vent 113 and the second vent 114 is as far as possible. For example, by setting the first vent 113 and the second vent 114 on opposite sides of this common surface, the flow path of the heating air duct within the main unit cabinet 110 is extended as much as possible, improving the heating effect.

[0037] In one specific embodiment, a partition 115 is provided inside the main unit cabinet 110, dividing the internal space of the main unit cabinet 110 into two cavities, namely a first cavity 111 and a second cavity 112. The partition 115 serves as the common surface of the first cavity 111 and the second cavity 112. Openable and closable openings, namely a first ventilation port 113 and a second ventilation port 114, are provided at opposite edges of the partition 115. Opening or closing these openings creates an open or closed heating air duct. For example, inside the main unit cabinet 110, when the surface of the partition 115 is parallel to the direction of gravity, the first ventilation port 113 and the second ventilation port 114 are respectively provided at the upper and lower ends of the partition 115.

[0038] In one embodiment, the first vent 113 includes a first fan, and the second vent 114 includes a second fan; wherein the airflow directions of the first fan and the second fan are opposite. Specifically, the first fan is provided in the first vent 113, and turning on the first fan turns the first vent 113 into an open state, and turning off the first fan turns the first vent 113 into a closed state. The second fan is provided in the second vent 114, and turning on the second fan turns the second vent 114 into an open state, and turning off the second fan turns the second vent 114 into a closed state. Simultaneously turning on both the first and second fans turns the heating air duct into an open state. The airflow directions of the first fan and the second fan are opposite when they are operating; for example, the first fan drives the air in the second cavity 112 to flow into the first cavity 111, and the second fan drives the air in the first cavity 111 to flow into the second cavity 112. In another embodiment, the first fan can also drive the air in the first cavity 111 to flow into the second cavity 112, and the second fan can drive the air in the second cavity 112 to flow into the first cavity 111. The resulting airflow direction can be referenced. Figure 2 As indicated by the middle arrow.

[0039] The first and second fans can be either single fans or fan groups containing multiple small fans.

[0040] In one embodiment, the main unit cabinet 110 is provided with a main unit louver 118, which closes when the heating air duct is open, so that the main unit cabinet 110 enters a semi-enclosed state. Specifically, louvers are provided on the side wall or other locations of the main unit cabinet 110. Under normal circumstances, the louvers are open, and when the main unit 100 is working, the heat generated by the internal working module can be exhausted to the outside through the open louvers. When the external temperature is too low, the main unit 100 is triggered to enter the heating mode. When the heating air duct is opened, the louvers are triggered to close, so that the main unit cabinet 110 forms a relatively enclosed space. However, since there are still gaps between the louver blades, air can flow through these gaps. Therefore, the main unit cabinet 110 can be understood as being in a semi-enclosed state at this time.

[0041] In one embodiment, the terminal cabinet 210 is equipped with terminal louvers (not shown in the figure). The terminal louvers close when the gas transmission channel 300 is opened, so that the terminal cabinet 210 enters a semi-enclosed state. Specifically, louvers are provided on the side wall or other locations of the terminal cabinet 210. Under normal circumstances, the louvers are open, and the heat generated by the internal working module can be discharged to the outside through the open louvers when the terminal 200 is working. When the external temperature is too low, the terminal 200 is triggered to enter the heating mode. When the gas transmission channel 300 is opened, the louvers are triggered to close, so that the terminal cabinet 210 forms a relatively enclosed space. However, since there are still gaps between the louver blades, air can flow through these gaps. Therefore, the terminal cabinet 210 can be understood as being in a semi-enclosed state at this time.

[0042] like Figure 4 As shown, in one embodiment, the gas transmission channel 300 includes a first pipe 310, a second pipe 320, a check valve 330, and an air pump 340. The first end of the first pipe 310 is connected to the main unit cabinet 110, and the second end of the first pipe 310 is connected to the first end of the second pipe 320. The second end of the second pipe 320 is connected to the air pump 340 via the check valve 330. The air pump 340 is located inside the terminal cabinet 210, and the gas transmission channel 300 is opened when the air pump 340 is operating. Specifically, in the gas transmission channel 300, the first end of the first pipe is used to connect to the main unit cabinet 110, the second end of the first pipe 310 is used to connect to the first end of the second pipe, and the second end of the second pipe is connected to the corresponding terminal cabinet 210. Simultaneously, the second end of the second pipe 320 is equipped with a check valve 330 and an air pump 340. Starting the air pump 340 opens the gas transmission channel 300. It should also be understood that there are corresponding gas transmission channels 300 between the host cabinet 110 and the terminal cabinet 210, and all gas transmission channels 300 may include the first pipe 310 and the second pipe 320.

[0043] In one scenario, some or all gas transmission channels 300 share a first pipe 310. Multiple gas transmission channels 300 can share the first pipe 310, which has multiple second ends, each connected to a first end of a plurality of second pipes 320. The number of second pipes 320 is determined by the number of terminals 200; that is, there can be multiple second pipes 320. The first end of each second pipe 320 is connected to the second end of the first pipe 310. Each terminal 200 has its corresponding air pump 340 individually controlled. The open state of a gas transmission channel 300 is understood to correspond to that terminal 200. When a terminal 200 enters heating mode, its corresponding air pump 340 starts, and the gas transmission channel 300 corresponding to that terminal 200 opens. The states of the gas transmission channels 300 corresponding to other terminals 200 are not affected. Simultaneously, a check valve 330 is used to prevent gas inside the terminal cabinet 210 from entering the main unit cabinet 110.

[0044] Optionally, the gas transmission channel 300 also includes insulation layers disposed on the outside of the first pipe 310 and the second pipe 320. That is, in order to ensure that the hot air does not experience a significant temperature drop during the process of entering the terminal cabinet 210 from the host cabinet 110, insulation layers can be disposed on the outside of both the first pipe 310 and the second pipe 320 to reduce the heat dissipation rate of the gas in the gas transmission channel 300 and ensure the heating effect of the terminal cabinet 210.

[0045] Optionally, the first cavity 111 is used to house the charger's control module 116, and the second cavity 112 is used to house the charger's power module 117; the first end of the gas transmission channel 300 is connected to the second cavity 112. Specifically, in the main unit cabinet 110, the first cavity 111 can be used to house the charger's control module 116, corresponding to the charger's control compartment, and the second cavity 112 can be used to house the charger's power module 117, corresponding to the charger's module compartment. When the main unit 100 enters the heating mode, it is actually the power module in the second cavity 112 that works and generates heat, heating the air inside the main unit cabinet 110. That is, compared to the first cavity 111, the gas temperature in the second cavity 112 is higher temperature gas; therefore, the first end of the gas transmission channel 300 is connected to the second cavity 112 to transmit the higher temperature gas to the terminal cabinet 210.

[0046] In one specific embodiment, the first end of the gas transmission channel 300 is connected to the bottom of the second cavity 112. Considering that the main unit cabinet 110 may also have heating requirements, while ensuring the hot air circulation path inside the main unit cabinet 110, hot air is obtained from the bottom of the second cavity 112 and enters the terminal cabinet 210 through the gas transmission channel 300, so as to avoid the situation where all the hot air in the second cavity 112 enters the terminal cabinet 210 and the main unit cabinet 110 cannot be heated.

[0047] Optionally, the second end of the gas transmission channel 300 is connected to the lower side of the terminal cabinet 210. Specifically, considering that hot air has a low density and rises, the second end of the gas transmission channel 300 can be connected to the lower side of the terminal cabinet 210. That is, after the hot air enters the terminal cabinet 210 from the lower side, it flows upward inside the terminal cabinet 210 to heat the inside of the terminal 200 cabinet.

[0048] In one specific embodiment, the second end of the gas transmission channel 300 is connected to the bottom of the terminal cabinet 210. This arrangement allows the transmission gas to enter the terminal cabinet 210 directly from the bottom.

[0049] In embodiments of this invention, the conditions for the host 100 and the terminal 200 to enter the heating mode can be set to be the same, or the conditions for the host 100 and the terminal 200 to enter the heating mode can be set to be the same. The host 100 then heats the terminal 200, eliminating the need for a separate heating module for the terminal 200. Heating is achieved simply through the flow of hot air, enabling the charger to operate in low-temperature environments and meeting the needs of various cold-climate usage scenarios.

[0050] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
