[0035] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0036] like Figures 1 to 4As shown, in one embodiment, the charging pile 100 includes a cabinet 10, a charging module 20, a power distribution module 30 and a charging gun; the charging module 20 and the power distribution module 30 are both installed in the cabinet 10, and the charging gun is located outside the cabinet 10. There are multiple charging modules 20, and the power distribution module 30 can connect at least two charging modules 20 in parallel to form a charging module, and the charging module charges the target object through the charging gun. Among them, the target object can be an electric car, etc.

[0037] The charging module obtained by connecting the corresponding charging modules 20 in parallel through the power distribution module 30 has a greater output power than a single charging module 20, so that the charging gun can charge the target object with a larger power, thereby improving the charging effect. For example, the output power of a single charging module 20 can be 120kW, and when 6 charging modules 20 are connected in parallel, 720KW of power can be output externally.

[0038] like Figure 1 and Figure 3 As shown, in one embodiment, the cabinet 10 includes a cabinet body 1, a first cabinet door 2 and a second cabinet door 3; the cabinet body 1 has a first chamber 11 and a second chamber 12 which are spaced apart; the first chamber 11 is used to install the charging module 20, and the second chamber 12 is used to install the power distribution module 30; the first chamber 11 forms a first opening on the cabinet body 1, and the second chamber 12 forms a second opening on the cabinet body 1; the first cabinet door 2 is movably connected to the cabinet body 1 for opening or closing the first opening; the second cabinet door 3 is movably connected to the cabinet body 1 for opening or closing the second opening.

[0039] When charging the target object, the charging module 20 will generate a large amount of heat, especially when charging the target with high power, the charging module 20 will generate more heat, which is likely to have an adverse effect on the power distribution module 30 and the like. In this embodiment, the charging module 20 and the power distribution module 30 are respectively installed in different chambers, and the heat generated by the charging module 20 is mainly concentrated in the first chamber 11, which can reduce the adverse effect of the heat on the power distribution module 30, thereby providing a guarantee for the normal operation of the charging pile 100.

[0040] In addition, the openings of the two chambers are opened or closed respectively by different cabinet doors. When it is necessary to install and maintain the device in a certain chamber, it is only necessary to open the cabinet door corresponding to the chamber, which is convenient for operation. Moreover, when there is a lot of heat in the first chamber 11, the first cabinet door 2 can also be opened alone to speed up the speed at which the temperature in the first chamber 11 diffuses outward. At this time, there is no need to open the second cabinet door 3 alone, so that the device in the second chamber 12 can be protected by the second cabinet door 3, reducing the probability of its being damaged.

[0041] It should be understood that when the first cabinet door 2 opens the first opening, devices can be installed into the first chamber 11 from the first opening, and devices in the first chamber 11 can also be taken out from the first opening. When the first cabinet door 2 closes the first opening, the first cabinet door 2 seals the first chamber 11, and at this time, devices such as the charging module 20 are sealed in the first chamber 11.

[0042] In addition, when the first cabinet door 2 closes the first opening, the first cabinet door 2 may be located outside the first chamber 11 and may completely cover the first opening.

[0043] The first chamber 11 usually extends along the first direction, and the arrangement direction of the first chamber 11 and the second chamber 12 is the second direction, and the angle between the first direction and the second direction is greater than 0 degrees and less than 180 degrees. Usually, the first direction is perpendicular to the second direction, and in this case, the first direction can be the front-to-back direction, and the second direction is the left-to-right direction. Figures 1 to 4 In the directions of whether, the first direction is parallel to the X-axis and the second direction is parallel to the Y-axis.

[0044] When the first cabinet door 2 closes the first opening, in an orthographic projection on a plane perpendicular to the first direction, the projection of the first opening is completely within the projection of the first cabinet door 2. When the first cabinet door 2 opens the first opening, in an orthographic projection on a plane perpendicular to the first direction, the projection of the first opening may not overlap with the projection of the first cabinet door 2 or may only partially overlap.

[0045] When the second cabinet door 3 opens the second opening, devices can be installed into the second chamber 12 from the second opening, and devices in the second chamber 12 can also be taken out from the second opening. When the second cabinet door 3 closes the second opening, the second cabinet door 3 seals the second chamber 12, and at this time, devices such as the charging module 20 are sealed in the second chamber 12.

[0046] In addition, when the second cabinet door 3 closes the second opening, the second cabinet door 3 may be located outside the second chamber 12 and may completely cover the second opening.

[0047] In addition, the second chamber 12 also extends along the first direction, and when the second cabinet door 3 closes the second opening, in an orthographic projection on a plane perpendicular to the first direction, the projection of the second opening is completely located within the projection of the second cabinet door 3. When the second cabinet door 3 opens the second opening, in an orthographic projection on a plane perpendicular to the first direction, the projection of the second opening may not overlap with the projection of the second cabinet door 3 or may only partially overlap.

[0048] like Figure 1 As shown, in one embodiment, the first opening and the second opening are located on the same side of the cabinet 1 , that is, in the first direction, the first cabinet door 2 and the second cabinet door 3 are located on the same side of the cabinet 1 , which is convenient for operation.

[0049] like Figure 2 and Figure 4 As shown, in one embodiment, the first chamber 11 forms a third opening on the cabinet 1, and the second chamber 12 forms a fourth opening on the cabinet 1; in the first direction, the first opening and the third opening are respectively located on opposite sides of the cabinet 1, and the second opening and the fourth opening are respectively located on opposite sides of the cabinet 1; the cabinet 10 also includes a third cabinet door 4 and a fourth cabinet door 5; the third cabinet door 4 is movably connected to the cabinet 1 for opening or closing the third opening; the fourth cabinet door 5 is movably connected to the cabinet 1 for opening or closing the fourth opening.

[0050] In this way, the corresponding components in the first chamber 11 and the second chamber 12 can be taken and placed in the front and rear directions, making the assembly and maintenance of the charging pile 100 simpler and more convenient. Moreover, when the temperature in the first chamber 11 is too high, the first cabinet door 2 and the second cabinet door 3 can also be opened at the same time, which can further improve the heat dissipation efficiency.

[0051] When the third cabinet door 4 closes the third opening, in an orthographic projection on a plane perpendicular to the first direction, the projection of the third opening is completely within the projection of the third cabinet door 4. When the third cabinet door 4 opens the third opening, in an orthographic projection on a plane perpendicular to the first direction, the projection of the third opening may not overlap with the projection of the third cabinet door 4 or may only partially overlap.

[0052] When the fourth cabinet door 5 closes the fourth opening, in an orthographic projection on a plane perpendicular to the first direction, the projection of the fourth opening is completely within the projection of the fourth cabinet door 5. When the fourth cabinet door 5 opens the fourth opening, in an orthographic projection on a plane perpendicular to the first direction, the projection of the fourth opening may not overlap with the projection of the fourth cabinet door 5 or may only partially overlap.

[0053] like Figure 1 and Figure 2 As shown, in one embodiment, the first cabinet door 2 is provided with a first ventilation hole 21, and the first ventilation hole 21 passes through the first cabinet door 2; when the first cabinet door 2 closes the first opening, the first chamber 11 is communicated with the first ventilation hole 21, and can be communicated with the outside of the cabinet body 1 through the first ventilation hole 21; the third cabinet door 4 is provided with a second ventilation hole 41; when the third cabinet door 4 closes the third opening, the first chamber 11 is communicated with the second ventilation hole 41, and can be communicated with the outside of the cabinet body 1 through the second ventilation hole 41.

[0054] After the charging pile 100 is assembled, there will be a certain gap between the charging module 20 and the inner surface of the first chamber 11, and there will also be a certain gap between adjacent charging modules 20. When the first cabinet door 2 closes the first opening and the third cabinet door 4 closes the third opening, in the first direction, the first ventilation hole 21, the first chamber 11 and the second ventilation hole 41 are connected to form a ventilation duct, and external air can pass through the cabinet 1 from the ventilation duct, which improves the efficiency of heat discharge in the first chamber 11.

[0055] like Figure 3 As shown, in one embodiment, the cabinet 10 further includes a filter 6, which is mounted on the first cabinet door 2 and opposite to the first ventilation hole 21. The filter 6 can reduce dust from entering the first chamber 11 from the first ventilation hole 21.

[0056] The filter screen 6 and the first vent hole being relative may mean that when the first cabinet door 2 closes the first opening, in an orthographic projection on a plane perpendicular to the first direction, the projection of the filter screen 6 and the projection of the first vent hole at least partially overlap.

[0057] In one embodiment, the filter screen 6 may be installed on the inner surface of the first cabinet door 2. When the first cabinet door 2 closes the first opening, the outer surface of the first cabinet door 2 is the surface away from the first chamber 11, and the inner surface of the first cabinet door 2 is the surface close to the first chamber 11. In addition, the first ventilation hole 21 actually runs from the inner surface of the first cabinet door 2 to the outer surface of the first cabinet door 2.

[0058] like Figure 4 As shown, the cabinet 10 further includes a heat dissipation fan 71, which is mounted on the third cabinet door 4 and opposite to the second ventilation hole 41. The heat dissipation fan 71 can be arranged to more quickly transport the gas in the first chamber 11 from the second ventilation hole to the outside of the cabinet 1, thereby accelerating heat dissipation.

[0059] The heat dissipation fan 71 and the second vent hole are relative to each other, which means that when the third cabinet door 4 closes the third opening, in an orthographic projection on a plane perpendicular to the first direction, the projection of the heat dissipation fan 71 and the projection of the second vent hole at least partially overlap.

[0060] In one embodiment, the heat dissipation fan 71 may be installed on the inner surface of the third cabinet door 4 .

[0061] When the third cabinet door 4 closes the third opening, the outer surface of the third cabinet door 4 is the surface facing away from the first chamber 11, and the inner surface of the third cabinet door 4 is the surface close to the first chamber 11. In addition, the second ventilation hole 41 actually runs from the inner surface of the third cabinet door 4 to the outer surface of the third cabinet door 4.

[0062] In addition, there may be multiple cooling fans 71 , and the cooling fans 71 may be arranged in an array.

[0063] like Figure 4 As shown, the charging pile 100 also has a fan speed regulation module 72, which is used to adjust the rotation speed of each cooling fan 71. The fan speed regulation module 72 is installed on the third cabinet door 4 and is located below the cooling fan 71. When the third cabinet door 4 closes the third opening, the fan speed regulation module 72 is located in the second chamber 12.

[0064] like Figure 3 As shown, in one embodiment, the cabinet 1 is a rectangular parallelepiped structure as a whole, which includes a first plate 13, a second plate 14, a third plate 15, a fourth plate 16 and a fifth plate 17. The first plate 13, the second plate 14 and the third plate 15 are arranged at intervals along the second direction, and the fourth plate 16 and the fifth plate 17 are arranged at intervals along the third direction, wherein the first direction, the second direction and the third direction intersect each other. In one scenario, the third direction is perpendicular to the first direction, and the third direction is perpendicular to the second direction, and the third direction is a vertical direction. Wherein, the third direction is parallel to the Z axis.

[0065] In addition, the first plate 13, the second plate 14 and the third plate 15 are connected to the fourth plate 16 and the fifth plate 17 at both ends in the third direction. The first plate 13, the third plate 15, the fourth plate 16 and the fifth plate 17 are connected to form a rectangular parallelepiped structure, and the four are enclosed to form a receiving cavity, the second plate 14 is arranged in the receiving cavity, and the receiving cavity is divided into two chambers, which are the first chamber 11 and the second chamber 12, wherein the first chamber 11 is located between the first plate 13 and the second plate 14, and the second chamber 12 is located between the second plate 14 and the third plate 15.

[0066] In one scenario, the first chamber 11 and the second chamber 12 are also rectangular parallelepiped spaces.

[0067] In one embodiment, the first plate 13, the third plate 15, the fourth plate 16 and the fifth plate 17 can all be metal plates, and the materials of the four plates can be the same. In addition, the material of the metal plate can be steel, iron, etc. The second plate 14 can be a heat insulation plate, such as a rock wool board, etc. Of course, the second plate 14 can also be a metal plate, and the materials of the first plate 13, the second plate 14, the third plate 15, the fourth plate 16 and the fifth plate 17 can be the same.

[0068] like Figure 3As shown, in one embodiment, the cabinet 10 also includes a first partition 81, which is arranged in the first chamber 11 and divides the first chamber 11 into a first space 111 and a second space 112; the first space 111 is located above the second space 112, the first space 111 is used to install the charging module 20, and the second space 112 is used to install the AC / DC conversion module 40; when the first cabinet door 2 closes the first opening, the first space 111 is connected to the first ventilation hole 21; when the third cabinet door 4 closes the third opening, the second space 112 is connected to the second ventilation hole 41.

[0069] The AC / DC conversion module 40 is connected to the charging module 20 and is also used to connect to the mains. The AC / DC conversion module 40 is used to convert the mains into direct current and charge the charging module 20.

[0070] The heat generated by the charging module 20 will heat the air around it, and the heated air will rise, so the temperature above the first space 111 is usually relatively high. The first space 111 is arranged above the second space 112, which is also conducive to reducing the adverse effects of the heat generated by the charging module 20 on the work of the AC-DC conversion module 40. Moreover, the AC-DC conversion module 40 is arranged at the bottom, which is also convenient for it to be connected to the mains from the bottom of the cabinet 1.

[0071] In addition, both ends of the first separator 81 are connected to the first plate 13 and the second plate 14 , respectively.

[0072] In addition, when the third cabinet door 4 closes the third opening, the heat dissipation fan 71 is located in the first space 111 , and the fan speed regulating module 72 is located in the second space 112 .

[0073] like Figure 3 As shown, in one embodiment, the cabinet 10 further includes a second partition 82, which is disposed in the second chamber 12 and divides the second chamber 12 into a third space 121 and a fourth space 122; the third space 121 is located above the fourth space 122, the third space 121 is used to install a control unit 301 of the power distribution module 30, and the fourth space 122 is used to install a power switching unit 302 of the power distribution module 30. The control unit 301 is used to control the switching unit 302 to work so that the corresponding charging modules 20 are connected in parallel.

[0074] Separating the control unit 301 and the switching unit 302 can facilitate assembly and maintenance. Moreover, the control unit 301 will also generate heat when working. Installing the control unit 301 and the switching unit 302 in different spaces can also reduce the adverse effects of the heat generated by the control unit 301 on the switching unit 302.

[0075] In addition, both ends of the second separator 82 are connected to the second plate 14 and the third plate 15 , respectively.

[0076] It should be understood that in an actual scenario, the cabinet 10 may be provided with both the first partition 81 and the second partition 82 , or the cabinet 10 may be provided with only one of the first partition 81 and the second partition 82 .

[0077] like Figure 3 As shown, in one embodiment, in the arrangement direction of the first chamber 11 and the second chamber 12, the first cabinet door 2 is located on the side of the first chamber 11 away from the second chamber 12, and the second cabinet door 3 is located on the side of the second chamber 12 away from the first chamber 11; that is, in the second direction, the first cabinet door 2 and the second cabinet door 3 are respectively connected to the opposite sides of the cabinet body 1, so that when the first cabinet door 2 and the second cabinet door 3 are opened, interference between the two can be avoided.

[0078] Specifically, the first cabinet door 2 is connected to the first plate 13 , and the second cabinet door 3 is connected to the third plate 15 .

This arrangement makes it easier to open and close the first cabinet door 2 and the second cabinet door 3.

[0081] In addition, the first axis and the second axis are both perpendicular to the first direction, and are both perpendicular to the second direction. At this time, the first axis and the second axis are both parallel to the vertical direction.

[0082] When the first cabinet door 2 closes the first opening, the first cabinet door 2 may abut against the second plate 14 , and when the second cabinet door 3 closes the second opening, the second cabinet door 3 may abut against the second plate 14 .

The indicator light 70 can emit light of different colors, and thus can output corresponding prompt information to the user.

[0089] The indicator light 70 may be installed on the second cabinet door 3, wherein the indicator light 70 may be installed on the outer surface of the second cabinet door 3. When the second cabinet door 3 closes the second opening, the outer surface of the second cabinet door 3 is the surface away from the second chamber 12, and the inner surface of the second cabinet door 3 is the surface close to the second chamber 12.

[0090] like Figure 4 As shown, in one embodiment, the charging pile 100 further includes a corresponding intermediate relay 80 , which is connected to the main control module 60 and is used to control the on and off of the corresponding circuit. The intermediate relay 80 may be installed in the third space 121 .

[0091] like Figure 1 andFigure 3 As shown, in one embodiment, the charging pile 100 further includes an emergency stop button 90. The emergency stop button 90 is installed on the outer surface of the second cabinet door 3. The emergency stop button 90 can cut off the electrical connection between the charging module 20 and the charging gun, and the emergency stop button 90 can also conduct the electrical connection between the charging module 20 and the charging gun.

[0092] In one embodiment, the number of charging guns is multiple. Different charging modules can charge the target object through different charging guns; at least one liquid-cooled charging gun is included in the multiple charging guns. The liquid-cooled charging gun can be applied to charge the target object with high power. The liquid-cooled charging gun can realize cooling the charging gun by means of liquid cooling, thereby avoiding damage to the charging gun during high-power charging. In addition, the liquid-cooled charging gun can adopt an existing design.

[0093] As Figure 5 shown, this figure shows a power switching matrix. In the example shown in this figure, the charging modules 20 and the output modules 1a are in one-to-one correspondence. Each charging module 20 is connected to its corresponding output module 1a. Specifically, the positive electrode of the charging module 20 can be electrically connected to the positive terminal of its corresponding output module 1a through a wire, and the negative electrode of the charging module 20 can be electrically connected to the negative terminal of its corresponding output module 1a through a wire. The positive terminal and the negative terminal of each output module 1a can be respectively electrically connected to the positive and negative electrodes of the charging gun. When the positive terminal and the negative terminal of an output module 1a are respectively electrically connected to the positive and negative electrodes of the charging gun, the charging module 20 corresponding to this output module 1a can charge the target object through this charging gun. In this example, each charging module 20 can charge the target object with a power of 120 KW.

[0094] In addition, KD1 to KD12 and K1 to K40 in the figure all belong to the corresponding switching devices in the power switching unit 302. Both ends of these switching devices are respectively connected to the positive electrode and the negative electrode of the corresponding charging module 20. The control unit 301 is used to control the closing and opening of these switching devices. In addition, each switching device can be a corresponding relay or other components that can control the on and off of the circuit.

[0095] For example, two switching devices can be regarded as a group of devices. One switching device in a group of devices is respectively connected to the positive electrodes of two charging modules 20, and the other switching device in this group of devices is respectively connected to the negative electrodes of these two charging modules 20. When the two switching devices in this group of devices are both closed, the positive electrodes of these two charging modules 20 are electrically connected, and the negative electrodes of these two charging modules 20 are electrically connected. The two form a charging module group, and this charging module group can connect a charging gun from one output module 1a, thereby realizing charging the target object with a power of 240 KW.

[0096] In Figure 5 the illustrated example, when K1, K2, K3, K4, K5, K6, K7, K8, K19, and K20 are closed simultaneously, six charging modules can be connected in parallel, and then the target object can be charged at a power of 720 KW.

[0097] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
