DETAILED DESCRIPTION

[0022] The utility model will be further described below in combination with the drawings and specific embodiments.

[0023] As Figures 1-4 shown, the control circuit module of the new energy vehicle gun body of the embodiment includes a first circuit board 1, a second circuit board 2, a third circuit board 3 and a fourth circuit board 4, and the control circuit of the new energy vehicle gun body is arranged on the first circuit board 1, the second circuit board 2, the third circuit board 3 and the fourth circuit board 4, wherein the first circuit board 1 and the second circuit board 2 are arranged in parallel, the third circuit board 3 and the fourth circuit board 4 are respectively connected to the opposite sides of the main function and the second circuit board 2, so as to form an accommodation space 5 together with the first circuit board 1 and the second circuit board 2, and the electronic components on the first circuit board 1, the second circuit board 2, the third circuit board 3 and the fourth circuit board 4 are at least partially staggered and arranged in the accommodation space 5. The second circuit board 2 is electrically connected with the first circuit board 1, the third circuit board 3 and the fourth circuit board 4 respectively, and the third circuit board 3 and the fourth circuit board 4 are electrically connected with the first circuit board 1 respectively.

[0024] According to the function and use scene of the new energy vehicle gun body, the new energy vehicle gun body includes a charging gun, a discharging gun and a charging and discharging integrated gun. The control circuit controls the charging and discharging functions of the charging gun / discharging gun / charging and discharging integrated gun. Charging refers to charging the new energy vehicle by the charging gun. Discharging refers to inserting the discharging gun into the new energy vehicle to discharge externally, which can supply power to outdoor electrical products. The control circuit of the charging gun can be the circuit with the publication number CN112467841B, and the control circuit of the charging and discharging integrated gun can be CN115693855A, CN115571014A, CN117284114A, etc.

[0025] The embodiment improves the compactness of the electronic component arrangement, improves the space utilization, thereby reducing the size of the control circuit module of the new energy vehicle gun body, facilitating the miniaturization and light weight of the charging and discharging integrated gun, and then improving the portability of the charging and discharging integrated gun.

[0026] Based on the mounting mode and structural characteristics of electronic components, electronic components can be divided into patch components and plug-in components. The plug-in component is relatively large in size and heavy in weight, and its pin needs to be inserted into the through hole of the circuit board and then welded. The plug-in component occupies a large space, which is not conducive to the miniaturization of the control circuit module of the new energy vehicle gun body. In addition, the first circuit board 1, the second circuit board 2, the third circuit board 3 and the fourth circuit board 4 have different functions, and the types and quantities of plug-in components on them are different. If the plug-in components on them are arranged on the outer side surface, it will cause a great waste of space. Therefore, the plug-in components on the first circuit board 1, the second circuit board 2, the third circuit board 3 and the fourth circuit board 4 are arranged on the inner side surface, and the plug-in components among the four are staggered and arranged in the accommodation space 5. The plug-in components on each board are arranged adjacent to each other and compactly, which is conducive to improving the space utilization efficiency and facilitating the miniaturization of the control circuit module of the new energy vehicle gun body.

[0027] In addition, a large number of patch components are also arranged on each board. The patch component is relatively small in size and occupies a small space, so the patch component can be arranged on the inner and outer side surfaces of each board.

[0028] It can be understood that the arrangement position of the electronic components on each board in the accommodation space 5 can be adjusted according to actual conditions. In the embodiment, the second circuit board 2 and the first circuit board 1 are arranged in parallel, and the electronic components on the opposite surfaces of the two boards are arranged in parallel. The plug-in components on the opposite surfaces of the third circuit board 3 and the fourth circuit board 4 are distributed between the electronic components on the second circuit board 2 and the first circuit board 1.

[0029] Due to functional limitations, there are more large plug-in components on the second circuit board 2 than on other boards. In order to further improve the compactness of the space layout, the lengths L2, L3 and L4 of the first circuit board 1, the third circuit board 3 and the fourth circuit board 4 are all less than the length L1 of the second circuit board 2, and the three are arranged in the middle of the second circuit board 2. This can save the material of other boards, reduce the cost, and expose the wiring ends at the front and rear ends of the second circuit board 2, which is convenient for wiring.

[0030] In the embodiment, the electrical connection between the boards is realized by connectors, specifically as follows: the second circuit board 2 is electrically connected with the first circuit board 1 through the first connector 6; the third circuit board 3 is electrically connected with the second circuit board 2 through the second connector 7 and electrically connected with the first circuit board 1 through the third connector 8; the fourth circuit board 4 is electrically connected with the second circuit board 2 through the fourth connector 9 and electrically connected with the first circuit board 1 through the fifth connector 10.

[0031] The connector types are various, in order to save space, miniaturize the control circuit module of the new energy vehicle gun body, the connectors of the embodiment all adopt the pin header, since the second circuit board 2 and the first circuit board 1 are parallel, the first connector 6 adopts the straight pin header, since the third circuit board 3 and the fourth circuit board 4 are perpendicular to the second circuit board 2 and the first circuit board 1 respectively, the second to fifth connectors adopt the bent pin header. The pin header structure is compact, which is helpful to realize high-density installation, the pin header connection also has high reliability and good electrical performance, and can also play a certain fixing role.

[0032] In addition, the third circuit board 3 and the fourth circuit board 4 of the embodiment are directly connected with the second circuit board 2 and the first circuit board 1 through plug-in connection, in order to be reinforced twice. In a feasible option of the embodiment, a certain board margin is reserved on the left and right sides of the second circuit board 2 to assemble with the gun shell of the charging and discharging integrated gun through the sliding groove mode, and the board margin W is preferably greater than or equal to 1.5 mm. Correspondingly, at least one jack 11 is formed on the left and right sides of the second circuit board 2 and the first circuit board 1 respectively, and at least one plugboard 12 is formed on the upper and lower sides of the third circuit board 3 and the fourth circuit board 4 respectively, which is inserted into the corresponding jack 11, so as to realize the direct plug-in connection of the third circuit board 3 and the fourth circuit board 4 with the second circuit board 2 and the first circuit board 1 respectively.

[0033] Although the utility model is specifically shown and introduced in combination with the preferred embodiment, it should be understood by those skilled in the art that various changes can be made to the utility model in form and detail without departing from the spirit and scope of the utility model defined in the appended claims, and all of them are within the protection scope of the utility model.
