[0041] In order to make the purpose, characteristics and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is explained in detail below by combining with the drawings of the specification.

[0042] In the following description, a lot of specific details are set forth in order to fully understand the utility model, but the utility model can also be implemented in other ways different from the description, and those skilled in the art can make similar generalization without departing from the connotation of the utility model, therefore the utility model is not limited by the following disclosed specific embodiments.

[0043] Secondly, the "one embodiment" or "embodiment" referred to here means that specific features, structures or characteristics can be included in at least one implementation of the utility model. "In one embodiment" does not mean the same embodiment in different places in the specification, and is not an independent or selective embodiment that excludes other embodiments.

[0044] Embodiment 1

[0045] Reference Figures 1-5 For the first embodiment of the utility model, the embodiment provides an automobile charging plug-in box, which can satisfy multiple vehicle charging at the same time, which comprises a box body 100, a power supply module 200 and an adjusting module 300. The power supply module 200 and the adjusting module 300 are arranged in the box body 100, the box body 100 is installed behind the dense busbar, the power supply module 200 is matched with the electric vehicle charging gun to supply power and supplement energy, the adjusting module 300 has the functions of monitoring the charging state of each vehicle, automatically distributing power and improving charging efficiency.

[0046] Specifically, the box body 100 comprises an inlet 101 and an outlet 102 arranged according to the power transmission direction, the box body 100 is connected with the power supply through the inlet 101, and the power is output through each outlet 102, and the outlet 102 is arranged not less than two, so as to meet the demand of multiple vehicle charging at the same time.

[0047] Further, the power supply module 200 includes a power supply circuit 201 connected between the input port 101 and the output ports 102, each of the output ports 102 is connected in parallel to the power supply circuit 201, and the power supply module 200 further includes a grounding circuit 202 for electrical safety protection. The current is transmitted from the input port 101 to the output ports 102 through the power supply circuit 201, and the parallel connection of the output ports 102 to the power supply circuit 201 allows the output ports 102 to independently perform output work.

[0048] The current distributor 301 connected in the main circuit of the power supply circuit 201, and the parallel structure between the output ports 102 divides the power supply circuit 201 into a main circuit and a branch circuit, and the current distributor 301 installed in the main circuit can be connected to each output port 102 in the branch circuit, and can be used to deliver power to each branch circuit according to the rated value.

[0049] The working principle of the current distributor 301 is based on the current distribution theorem and Ohm's law, which realizes the distribution and control of current by distributing current to different resistors. Specifically, the current distributor 301 will distribute the input current to different circuits according to the resistance value in the connected circuit and the current distribution ratio. The current distributor 301 is divided into one-in-two-out, one-in-three-out, one-in-four-out and one-in-six-out according to the output channel. In this embodiment, in order to meet the charging of multiple vehicles, the output port 102 is provided with six output ports, and the current distributor 301 can adopt a one-in-six-out SOC-AA6-1 model, including one input channel connected to the main circuit and six output channels connected to the branch circuit.

[0050] Further, the power supply circuit 201 of each branch is connected to the current monitor 302 and the voltage monitor 303 for real-time monitoring of the power output state of the output port 102. The current monitor 302 and the voltage monitor 303 are devices for measuring and monitoring the current and voltage in the circuit, which can be a simple ammeter or voltmeter, or a sensor integrated in a more complex system. The power supply module 200 further comprises a current protector connected to each branch of the power supply circuit 201. The current protector is an electrical device for protecting the safety of the circuit and the device, which can monitor the current in the circuit, and cut off the power supply in time when overload, short circuit and other faults occur, so as to avoid damage to the device or the occurrence of fire and other dangerous situations. Each branch is connected to the current monitor 302, the voltage monitor 303 and the current protector, which facilitates independent protection of each output port 102. The existing current protector is divided into electromagnetic residual current protector, electronic residual current protector and delay type residual current protector. The embodiment adopts a delay type residual current protector, which is a residual current protector specially designed to reach a predetermined limit of inaction time for a certain residual operating current value, mainly used as a protection device for the main line or branch line, which can cooperate with the protection device of the terminal line to meet the requirement of selective protection, and is suitable for the process of automatic protection from the start of charging to the disconnection of the full charge of a single charging gun.

[0051] In summary, by setting the box body 100, the power supply module 200 and the adjustment module 300 to cooperate, adopting the integrated bus structure design and the multi-way distribution circuit system, the plug-in box can efficiently distribute electric energy and support intelligent power adjustment for each charging port.

[0052] Embodiment 2

[0053] Reference Figures 1-6 For the second embodiment of the utility model, unlike the previous embodiment, the embodiment provides a heat dissipation module 500, which solves the problem of high heat of the plug-in box when multiple output ports 102 are charging at the same time.

[0054] Specifically, the heat dissipation module 500 comprises a heat dissipation groove 501 arranged through the outer wall of the box body 100, and a heat dissipation air duct 502 arranged in the box body 100 and communicating with the heat dissipation groove 501, wherein the heat dissipation air duct 502 passes through the power supply circuit 201. The heat dissipation groove 501 has a heat dissipation function and is a hole, a strip or other shaped groove structure, and the heat dissipation air duct 502 is a continuous interval, so that air can flow in the heat dissipation air duct 502, and then the heat generated at the power supply circuit 201 is discharged out of the box body 100 through the heat dissipation groove 501.

[0055] Further, the heat dissipation air duct 502 passes through each branch of the power supply circuit 201, that is, the heat dissipation air duct 502 is connected with the electrical equipment on each branch of the power supply circuit 201, so that the heat dissipation efficiency is improved.

[0056] The heat dissipation groove 501 is provided with at least two positions, the area of the heat dissipation outlet is increased, and the heat dissipation groove 501 is located at the top and the side of the box body 100 respectively. The heat dissipation air duct 502 is connected with the heat dissipation groove 501 at the top and the side of the box body 100 respectively. Since hot air has the characteristics of small density and upward movement, at least one end of the heat dissipation air duct 502 is connected with the side of the box body 100, the heat dissipation groove 501 at the side has a height difference with the heat dissipation groove 501 at the top, the heat dissipation air duct 502 passes through each branch, the output end of the heat dissipation air duct 502 is connected with the heat dissipation groove 501 at the top of the box body 100, so that the air flows into the heat dissipation groove 501 at the side of the box body 100 naturally, and finally the heat is discharged through the heat dissipation groove 501 at the top of the box body 100. The air has a general flow direction (as shown by the middle white arrow), so that the hot air cannot circulate in the box body 100 and cannot be discharged in time. Figure 3

[0057] Preferably, the heat dissipation module 500 further comprises a fan arranged in the box body 100, and an air outlet of the fan is connected with the heat dissipation air duct 502. By arranging the fan or an equivalent device for accelerating air flow, the air flow rate in the heat dissipation air duct 502 is accelerated, so that the heat dissipation efficiency and the cooling speed are improved.

[0058] The remaining structure is the same as that of example 1.

[0059] In summary, by arranging the heat dissipation module 500 for cooperation, the heat generated by the electronic devices on the power supply circuit 201 during operation is discharged out of the box body 100 through the heat dissipation groove 501, so that the problem of large heat during high-load work of the plug-in box is solved.

[0060] Example 3

[0061] Reference Figures 1-9 The third embodiment of the utility model is different from the previous embodiment, and the embodiment provides a connecting assembly 400, so that the box body 100 can be quickly and stably docked with a matched connecting object on the side of the inlet 101 or the outlet 102. The box body 100 is provided with the connecting assembly 400 on the side of the interface, and the connecting assembly 400 comprises a plug-in part 401 and a blocking part 402. The inlet 101 and the outlet 102 are power interfaces, the plug-in part 401 and the blocking part 402 are entity structures arranged on the interfaces, and are used for ensuring the stable connection of the circuit at the power interface.

[0062] ​Specifically, the inlet 101 is a standard interface adapted to the dense bus duct 600, which conforms to the national standard GB 7251.6-2015. The national standard GB 7251.6-2015 “Low-voltage switchgear and controlgear assemblies Part 6: Busbar trunking systems” was published on May 15, 2015 and implemented on June 1, 2016. Most of the dense bus ducts 600 on the market implement this standard, improving the applicability of the plug-in box.

[0063] Further, the outlet 102 is a standard interface adapted to the electric vehicle charging gun, which conforms to the national standard GB / T 20234.2-2015 for alternating current or the national standard GB / T 20234.3-2023 for direct current. GB / T 20234.2-2015 “Electric vehicle conductive charging connection devices Part 2: AC charging interface”: This standard specifies the structural dimensions of the domestic AC charging interface / gun head. GB / T 20234.3-2023 “Electric vehicle conductive charging connection devices Part 3: DC charging interface”: This standard specifies the functional definition and structural dimensions of the electric vehicle conductive DC charging interface, which is applicable to vehicle interfaces for charging mode 4 and connection method C in accordance with GB / T XXXX.1, with a rated working value of a DC rated voltage not exceeding 750V and a DC rated current not exceeding 400A. The outlet 102 can be adapted to the above-mentioned standard for alternating current or direct current to be applicable to most charging guns.

[0064] The plug-in part 401 is arranged at the interface and connected or separated with the mating object of the interface along the plug-in direction. The blocking part 402 blocks the plug-in direction of the plug-in part 401 and is movable to deviate from the plug-in direction of the plug-in part 401. In the embodiment, the power inlet 101 and the outlet 102 of the box body 100 are provided with the plug-in part 401. Taking the power inlet 101 side of the box body 100 as an example, the box body 100 is provided with the plug-in part 401 at the power inlet 101 side, which is matched with the structure of the socket 601 of the dense bus duct 600. After the plug-in part 401 of the box body 100 is aligned with the position of the socket 601 of the dense bus duct 600, the power inlet 101 of the box body 100 is in contact with the socket 601 of the dense bus duct 600 to make the circuit in communication, and the connection is quickly achieved by the plug-in mode. At this time, the plug-in part 401 is moved to block the movement of the plug-in part 401 along the plug-in direction, so as to prevent the plug-in part 401 from being separated, keep the power inlet 101 of the box body 100 in continuous contact with the socket 601 of the dense bus duct 600, and stabilize the power supply. When it is needed to disconnect, the plug-in part 401 is moved to deviate from the plug-in direction, so that the blocking of the plug-in part 401 is removed, and the plug-in part 401 can be separated from the dense bus duct 600 along the plug-in direction, so that the power inlet 101 is separated from the socket 601.

[0065] In a specific embodiment, as shown in Figure 9 The plug-in part 401 can be provided with a groove matched with the protruding structure of the socket 601. When the groove is inserted into the protruding block along the plug-in direction, the circuit of the power inlet 101 and the socket 601 is in communication. The blocking part 402 is an elastic block (which can be integrally arranged on the plug-in part 401) arranged on one side of the groove and extending towards the outer wall of the protruding block. The blocking part 402 can be inserted into the protruding block of the socket 601 together with the plug-in part 401 by elastic deformation, and when the deformation is restored, the extrusion force of the blocking part 402 to the protruding block of the socket 601 is applied. The direction of the extrusion force of the blocking part 402 is shown by the black arrow in the figure, which increases the resistance to pulling out. When it is needed to separate, the deformation direction of the elastic block can be pressed to weaken or eliminate the extrusion force of the elastic block to the protruding block, so as to smoothly complete the separation. In another embodiment, the blocking part 402 can also be provided with other common clamping block and clamping groove matching structure, movable limiting block, or threaded cooperation (as shown in Figure 8 ) and related deformation structures.

[0066] The remaining structures are the same as those of embodiment 2.

[0067] In summary, by arranging the connecting assembly 400, the dense bus can be quickly connected to realize stable power access, and most of the devices used in the market can be matched.

[0068] Embodiment 4

[0069] Referring to Figure 7For the fourth embodiment of the utility model, unlike the previous embodiment, the embodiment provides a charging station, which comprises an automobile charging plug-in box and a dense bus duct 600, and solves the problems of limited number of interfaces of existing charging equipment and poor expansibility.

[0070] Specifically, the automobile charging plug-in box is provided with a plurality of dense bus ducts 600, and a plurality of sockets 601 adapted to the automobile charging plug-in box. A plurality of automobile charging plug-in boxes are respectively connected with a plurality of dense bus ducts 600 to further increase the expansion number of the output port 102 and meet the demand of simultaneous charging of more electric vehicles.

[0071] The remaining structure is the same as that of embodiment 3.

[0072] It should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model and are not limited. Although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the utility model can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the utility model, and they should be covered in the scope of the claims of the utility model.
