[0020] This application provides an EVCC charging dock 1, including a port module 11, an EVCC module 12, and a housing 13. The housing 13 includes a bottom shell 131 and an end cap 132. The end cap 132 is fixed to one side of the bottom shell 131, and the bottom shell 131 and the end cap 132 are fastened together to form a receiving compartment 14. The receiving compartment 14 includes a port compartment 141 and an EVCC fixing compartment 142. The port module 11 is fixed to the port compartment 141, and the EVCC module 12 is inserted into the EVCC fixing compartment 142, and the EVCC module 12 is connected to the port module 11. With the bottom shell 131 as the base, the end cap 132 is fixed on top of the bottom shell 131, and the end cap 132 and the bottom shell 131 form the receiving compartment 14. This embodiment does not limit the structure of the receiving compartment 14; for example, refer to... Figure 6 As shown, Figure 6 for Figure 1The schematic diagram of the bottom shell 131 and port module 11 shows that an EVCC fixing compartment 142 is provided on the left side of the receiving compartment 14, and a port compartment 141 is provided on the right side of the receiving compartment 14. The EVCC module 12 is fixed to the EVCC fixing compartment 142, and the port module 11 is fixed to the port compartment 141.

[0021] like Figure 4 , Figure 5 As shown, Figure 4 for Figure 3 Enlarged view of the structure at point C; Figure 5 for Figure 1 Exploded view.

[0022] In some embodiments, the EVCC mounting chamber 142 has a limiting groove 1421 at its bottom. The EVCC module 12 includes a shock-absorbing element 121, which is fixed to the side of the EVCC module 12 near the bottom of the EVCC mounting chamber 142. The shock-absorbing element 121 is inserted into the limiting groove 1421 along a first direction; the first direction is the distribution direction of the bottom shell 131 and the end cover 132. Figure 6 As shown, a limiting groove 1421 is provided at the bottom of the EVCC fixing chamber 142 in a direction parallel to the EVCC module 12. When the EVCC module 12 is inserted along the first direction, the movement of the EVCC module 12 in the other two directions perpendicular to the first direction is restricted. Shock-absorbing elements 121 are provided on both sides of the EVCC module 12 near the bottom of the EVCC fixing chamber 142 along the first direction. A slot 1421a is provided on the inner side of the limiting groove 1421. The shock-absorbing element 121 is provided with a buckle 121a corresponding to the slot 1421a. The position of the EVCC module 12 in the EVCC fixing chamber 142 is reinforced by the cooperation between the buckle 121a and the slot 1421a.

[0023] In some embodiments, the EVCC module 12 includes a substrate 122, which includes a first substrate 1221 and a second substrate 1222. A shock-absorbing element 121 is fixed to the first substrate 1221. The bottom of the EVCC mounting chamber 142 is also provided with a support base 1422 for supporting the second substrate 1222. For example... Figure 3 , Figure 4 As shown, the EVCC module 12 includes a first substrate 1221 and a second substrate 1222, which are fixedly connected and inserted into the EVCC mounting chamber 142. In this embodiment, the volume of the second substrate 1222 is smaller than that of the first substrate 1221. In this embodiment, a support base 1422 is provided at the pre-insertion position of the second substrate 1222 to support the second substrate 1222, and a baffle 1423 is provided at the pre-insertion position of the second substrate 1222 away from the first substrate 1221 to restrict the movement of the second substrate 1222. Similarly, the same limiting method as the first substrate 1221 can be set. Limiting grooves 1421 are provided on both sides of the pre-insertion position of the second substrate 1222, i.e. the EVCC fixing chamber 142. Corresponding shock-absorbing elements 121 are provided on both sides of the second substrate 1222 along the first direction near the bottom of the EVCC fixing chamber 142. The limiting grooves 1421 and the shock-absorbing elements 121 are used to limit the position of the second substrate 1222. As long as the position of the second substrate 1222 can be limited.

[0024] like Figure 9 , Figure 10 as well as Figure 11 As shown, Figure 9 This is a schematic diagram of the structure of the third type of EVCC charging dock in the embodiments of this application; Figure 10 for Figure 9 Schematic diagram of the structure along the A' direction; Figure 11 for Figure 10 A cross-sectional view along the B'-B' direction. In this embodiment, the EVCC module 12 has only one substrate 122. The limiting method for the substrate 122 is as described above. The movement of the EVCC module 12 can be limited by the limiting method of the first substrate 1221 or the limiting method of the second substrate 1222, which can be selected according to the actual installation requirements.

[0025] like Figure 7 As shown, Figure 7 for Figure 1 Bottom view of the middle cover 132.

[0026] In some embodiments, the end cap 132 is provided with a limiting component located on the side of the end cap 132 near the EVCC module 12. The limiting component is used to restrict the movement of the EVCC module 12 along the first direction. The limiting component is provided inside the end cap 132 on the side near the EVCC module 12, and the end cap 132 is placed on top of the EVCC module 12, thereby restricting the movement of the EVCC module 12 along the first direction.

[0027] In some embodiments, the limiting component includes a fixing post 1321a and a fixing groove 1321b. The fixing post 1321a is located on the side of the end cap 132 near the first substrate 1221, and the fixing groove 1321b is located on the side of the end cap 132 near the second substrate 1222. The fixing groove 1321b is inserted into the second substrate 1222. It can be understood that two fixing posts 1321a are respectively provided on both sides of the end cap 132 corresponding to the first substrate 1221, and a slot is provided on the end cap 132 corresponding to the second substrate 1222, with the slot opening facing the second substrate 1222. When the end cap 132 is fixed to the bottom shell 131 along the first direction, the slot is inserted into the top of the second substrate 1222, and the fixing post 1321a contacts the top of the first substrate 1221, respectively fixing the first substrate 1221 and the second substrate 1222, thus restricting the movement of the first substrate 1221 and the second substrate 1222 along the first direction. Similarly, the end cap 132 can be configured as a slot at the position corresponding to the first substrate 1221, with the slot facing the first substrate 1221. When the end cap 132 is fixed to the bottom shell 131 along the first direction, the slot is inserted into the top of the first substrate 1221 to restrict the movement of the first substrate 1221 along the first direction. This can be set according to the actual situation, as long as it can restrict the movement of the first substrate 1221 and the second substrate 1222 along the first direction.

[0028] In some embodiments, the end cap 132 is an integrated design, comprising a first cover portion 1321 and a second cover portion 1322. The first cover portion 1321 mates with the EVCC module 12 and covers the EVCC module 12; the second cover portion 1322 mates with the port module 11 and covers the port module 11. For example, as... Figure 7 As shown, Figure 7 The left side is the first cover portion 1321 that matches the EVCC module 12, and the right side is the second cover portion 1322 that matches the port module 11. However, the first cover portion 1321 and the second cover portion 1322 are integrated into one design. By using one end cap 132 to seal the port module 11 and the EVCC module 12 in a unified manner, the assembly difficulty is reduced, the installation process is reduced, and material and labor costs are saved.

[0029] In some embodiments, the port module 11 includes an AC signal component 111 and a DC signal component 112, and the second cover portion 1322 is provided with corresponding DC cover portion 1322a and AC cover portion 1322b; the EVCC charging socket 1 also includes an AC rear cover 15 and a DC rear cover 16, the DC rear cover 16 including a first rear cover 161 and a second rear cover 162 disposed opposite to each other, the first rear cover 161 and the second rear cover 162 being fixed to the side of the DC cover portion 1322a away from the receiving compartment 14; the AC rear cover 15 is fixed to the side of the AC cover portion 1322b away from the receiving compartment 14. (Reference) Figure 3 As shown, Figure 3 The upper part is the first cover portion 1321, and the lower part is the second cover portion 1322. The port module 11 includes an AC signal component 111 and a DC signal component 112, corresponding to... Figure 3 The leftmost component is the DC signal assembly 112, and to its right is the AC signal assembly 111. To the left of the second cover portion 1322 is the DC cover portion 1322a, and to its right is the AC cover portion 1322b. The second cover portion 1322 is fixed to the port module 11 along the first direction. (Reference) Figure 8 As shown, Figure 8 This is a schematic diagram of the structure of the second type of EVCC charging socket in this application embodiment. The DC back cover 16 is fixed to the DC cover body 1322a, and the AC back cover 15 is fixed to the AC cover body 1322b. The DC back cover 16 and the AC back cover 15 are used to prevent accidental contact by the operator and to ensure reliability during the charging process. Furthermore, the DC back cover 16 includes a first back cover 161 and a second back cover 162 that are arranged opposite to each other. It can be understood that the first back cover 161 and the second back cover 162 are a mirror-symmetrical split design, which facilitates assembly and reduces molding and processing costs.

[0030] In some embodiments, the EVCC charging dock 1 further includes an AC signal transmission unit 17, and the EVCC module 12 includes a substrate 122, with the AC signal transmission unit 17 integrated into the substrate 122; or, the AC signal transmission unit 17 is fixed to the side of the port compartment 141 near the EVCC module 12, and the AC signal transmission unit 17 is connected to the AC signal component 111. Integrating the AC signal transmission unit 17 into the substrate 122 of the EVCC module 12, such as a temperature sensor for monitoring the power terminal of the AC terminal and an AC signal detection component, allows the EVCC module 12 to directly monitor the specific temperature of the power terminal or directly transmit AC signals, reducing the use of plug-ins and saving costs. Alternatively, the AC signal transmission unit 17 can be fixed to the side of the port compartment 141 near the EVCC module 12, and the AC signal transmission unit 17 can be connected to the AC signal component 111, as described in the reference. Figure 8 , Figure 9 As shown, Figure 8In the middle, the EVCC module 12 is located on the left side, and the AC signal transmission unit 17 is located above the port compartment 141. The EVCC module 12 is located to the left of the AC signal transmission unit 17. Figure 9 In the middle, the EVCC module 12 is located on the right, and the AC signal transmission unit 17 is located above the port compartment 141. The EVCC module 12 is located to the right of the AC signal transmission unit 17. This reduces the use of wiring harnesses and saves costs.

[0031] In some embodiments, the EVCC charging dock 1 further includes an electronic lock signal transmission unit 18, which is fixed to one side of the AC signal transmission unit 17. The AC signal transmission unit 17 has a through hole on the side of its base 1311 near the electronic lock signal transmission unit 18. The electronic lock signal transmission unit 18 includes a wire that passes through the through hole and connects to the AC signal transmission unit 17. (Reference) Figure 1 , Figure 8 , Figure 9 As shown, in Figure 1 and Figure 8 In the middle, an electronic lock signal transmission unit 18 is provided on the right side of the port module 11; in Figure 9 In the middle, an electronic lock signal transmission unit 18 is provided on the left side of the port module 11. An electronic lock is used to lock the charging gun, ensuring mechanical stability and electrical connection reliability during charging. Furthermore, the electronic lock can automatically disconnect in case of abnormality, thereby protecting the vehicle and charging equipment. A through hole is provided on the side of the AC signal transmission unit 17 near the base 1311 of the electronic lock signal transmission unit 18. The wires of the electronic lock signal transmission unit 18 are passed through the through hole and connected to the AC signal transmission unit 17, reducing the use of wiring harnesses.

[0032] In some embodiments, the EVCC charging dock 1 further includes an indicator light 19. The bottom shell 131 includes a base 1311 and a housing 1312. The indicator light 19 is fixed to the base 1311 and is located on one side of the housing 1312 near the EVCC module 12. The indicator light 19 is connected to the EVCC module 12. Figure 1 As shown, an indicator light 19 is provided on the left side of the EVCC module 12. The indicator light 19 is connected to the inside of the EVCC module 12 and is directly controlled by the EVCC module 12.
