[0002] With the rapid development of new energy vehicles, the demand for charging piles is also increasing day by day. A charging pile is generally connected to the power grid through an incoming line module, and its output end is provided with a charging gun, through which a new energy vehicle can be charged.

[0053] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and text descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed embodiments

[0054] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0055] In the description of the present application, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0056] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0057] An embodiment of the present application provides a charging pile, as Figure 1 shown, the charging pile includes a housing 1, a circuit board assembly 100, an incoming line module 4, and a network module 5. Among them, referring to Figure 2 , the interior of the housing 1 has an installation cavity 11; and, referring to Figure 1 , a wiring groove 12 is formed on the back of the housing 1, and the interior of the installation cavity 11 and the wiring groove 12 are separated by the groove wall of the wiring groove 12. In one example, as Figure 1 shown, the housing 1 includes a panel 13 and a lower housing 14, and the installation cavity 11 is formed between the panel 13 and the lower housing 14. Among them, the part of the lower housing 14 away from the panel 13 can be called the back plate of the housing 1, the part where the back plate is located can be called the back of the housing 1, the wiring groove 12 is formed on the side of the back plate away from the panel 13, the opening direction of the wiring groove 12 faces away from the panel 13, and the installation cavity 11 and the wiring groove 12 are separated by the back plate. The installation cavity 11 and the wiring groove 12 are used for installing and connecting different electrical components. Combining Figure 1 and Figure 2 it can be seen that the circuit board assembly 100 is located in the installation cavity 11. The incoming line module 4 includes a wiring terminal 41, and at least part of the wiring terminal 41 is located inside the wiring groove 12 and is electrically connected to the circuit board assembly 100.

[0058] At least part of the network module 5 is located in the installation cavity 11, the network module 5 and at least part of the circuit board assembly 100 are spaced apart and oppositely arranged in the opening direction of the wiring groove 12, the network module 5 includes a network interface 51, and the network interface 51 is exposed inside the wiring groove 12. It should be understood that in the embodiment of the present application, "the network module 5 and at least part of the circuit board assembly 100 are oppositely arranged in the opening direction of the wiring groove 12" means that the orthographic projection of the network module 5 along the opening direction of the wiring groove 12 can partially or completely overlap the orthographic projection of at least part of the circuit board assembly 100 along the opening direction of the wiring groove 12. In addition, it should be noted that the network interface 51 "is exposed" inside the wiring groove 12. The "exposed" method in the embodiment of the present application includes two cases. One case is that at least a part of the network interface 51 extends into the wiring groove 12; another case is that the network interface 51 does not extend into the wiring groove 12, but is installed on its edge, opening or adjacent structure (such as the side of the back plate close to the panel 13). Although the network interface 51 does not extend into the groove, its position is adjacent to the wiring groove 12, so the presence of the network interface 51 can be directly observed from the perspective inside the groove. It should be understood that the "exposed" in the following text has a similar meaning.

[0059] The charging pile provided by the embodiment of the present application forms an installation cavity 11 inside the housing 1 for installing the circuit board assembly 100; a wiring groove 12 is formed on the back of the housing 1 for installing the incoming line module 4 and exposing the network interface 51 of the network module 5, wherein both the incoming line module 4 and the network module 5 are electrically connected to the circuit board assembly 100. Among them, since the network module 5 and at least part of the circuit board assembly 100 are arranged at intervals and oppositely along the opening direction of the wiring groove 12, the wiring between the network module 5 and the circuit board assembly 100 is convenient. Moreover, since both the incoming line module 4 and the network interface 51 of the network module 5 are arranged or exposed on the back of the housing 1, the space on the panel 13 side of the housing 1 can be avoided, so the space utilization rate and layout rationality are improved. The solution of the present application is particularly suitable for small charging piles with a small volume. Of course, it can also be applied to large charging piles.

[0060] In some embodiments of the present application, as Figure 3 shown, the plate surface of the panel 13 is perpendicular to the opening direction of the wiring groove 12. The network module 5 has a first orthographic projection on the plate surface of the panel 13, and the circuit board assembly 100 has a second orthographic projection on the plate surface of the panel 13. The first orthographic projection is located within the second orthographic projection. Thus, when wiring the network module 5 and the circuit board assembly 100, the wire harness can be directly connected to the corresponding parts of the network module 5 and the circuit board assembly 100. Therefore, there is no need to wind the wire or adjust the wiring direction, which reduces the wiring difficulty, facilitates the operation, and has a short wiring distance.

[0061] It should be understood that generally, the wiring terminal 41 of the incoming line module 4 is adapted to be electrically connected to the strong power part in the circuit board assembly 100, and the network module 5 is adapted to be electrically connected to the weak power part in the circuit board assembly 100. Among them, the strong power part and the weak power part can be integrated in different areas on the same PCB (Printed Circuit Board), or arranged on two PCBs. For the convenience of description below, the case where the strong power part and the weak power part are respectively arranged on two PCBs is taken as an example for illustration, and those skilled in the art can easily infer the situation when the strong power part and the weak power part are integrated in different areas on the same PCB.

[0062] As Figure 1 shown, the circuit board assembly 100 includes a first circuit board 2 and a second circuit board 3. The first circuit board 2 is a strong power board for connecting to the wiring terminal 41 of the incoming line module 4; the second circuit board 3 is a weak power board for connecting to the network module 5. Among them, at least part of the network module 5 and the second circuit board 3 are arranged at intervals and oppositely along the opening direction of the wiring groove 12 to facilitate the wiring of the network module 5.

[0063] Generally speaking, a PCB includes a component side 31 and a soldering side 32. The component side 31 is the side of the PCB for mounting electronic components, and the soldering side 32 is the side of the PCB for soldering the pins of components. In some embodiments of the present application, as Figure 2 shown, a display screen 6 is mounted on the panel 13 of the charging pile. To facilitate the wiring of the display screen 6 of the charging pile, as Figure 4 shown, the component side 31 of the circuit board assembly 100 (such as the second circuit board 3) faces away from the network interface 51, and the soldering side 32 faces the network interface 51. A first connector 311 is provided on the component side 31; a via hole 33 is also provided on the circuit board assembly 100 (such as the second circuit board 3), and the network module 5 is connected to the first connector 311 through a connecting wire 34 passing through the via hole 33.

[0064] Optionally, the first connector 311 is a flexible cable connector, and the connecting wire 34 is a flexible flat cable. By using a flexible flat cable and a flexible cable connector for wiring, the operation is convenient and easy for wiring. The flexible flat cable has a certain deformation ability, which can prevent damage caused by excessive bending. Moreover, the cable slot of the flexible cable connector has an insertion self-locking function, which can effectively prevent the flexible flat cable from loosening.

[0065] In some embodiments, a second connector 53 is provided on the component side 31 of the circuit board assembly 100 (such as the first circuit board 2), and the incoming line module 4 can be connected to the second connector 53 by wiring. Optionally, the second connector 53 is a terminal block.

[0066] In some embodiments of the present application, both the incoming line module 4 and the network module 5 are connected to the lower housing 14.

[0067] In the case where the high-voltage part and the low-voltage part are integrated on the same PCB, the PCB can be connected to the panel 13, which facilitates the pre-wiring of the display screen 6. As long as the network module 5 and the wiring module are connected to the circuit board assembly 100 before the panel 13 and the lower housing 14 are closed. Or, the PCB can also be connected to the lower housing 14, which facilitates the pre-wiring of the network module 5 and the wiring module. As long as the circuit board assembly 100 is connected to the display screen 6 before the panel 13 and the lower housing 14 are closed.

[0068] In the case where the high-voltage part and the low-voltage part are located on different PCBs, the first circuit board 2 can be connected to the lower housing 14, and the second circuit board 3 can be connected to the panel 13. This facilitates the pre-wiring of the wiring module and the display screen 6. As long as the connecting wire 34 connected to the network module 5 is plugged into the connector on the second circuit board 3 before the panel 13 and the lower housing 14 are closed.

[0069] In some embodiments of the present application, as Figure 3 and Figure 5As shown, first openings 121 and second openings 122 are provided at intervals on the groove wall of the wiring groove 12, and the inside of the wiring groove 12 communicates with the installation cavity 11 through the first openings 121 and the second openings 122 respectively.

[0070] The terminal block 41 is installed in the first opening 121 and is electrically connected to the circuit board assembly 100 (such as the first circuit board 2). Exemplarily, the terminal block 41 is located inside the wiring groove 12 and is fixed on the back plate of the lower housing 14, and at least part of the terminal block 41 is exposed from the first opening 121. Therefore, the presence of the terminal block 41 can be directly observed through the first opening 121 from the perspective of the installation cavity 11. In this way, the wiring convenience between the terminal block 41 and the circuit board assembly 100 is improved.

[0071] The network module 5 is located in the installation cavity 11, and the network interface 51 is exposed from the second opening 122. Exemplarily, as Figure 6 and Figure 7 shown, the network interface 51 may include at least one of a SIM (Subscriber Identity Module) card slot 511 and a network cable interface 512 (such as an RJ-11 interface). During use, the user can directly insert a SIM card or a network cable into the network interface 51 along the arrow direction shown in Figure 7 inside the wiring groove 12. Therefore, the operation convenience of wiring or card insertion is improved.

[0072] In some embodiments of the present application, as Figure 6 shown, the network module 5 includes a third circuit board 52, and the network interface 51 is provided on the third circuit board 52. As Figure 8 and Figure 9 shown, the second opening 122 is located on the bottom wall 123 of the wiring groove 12. The bottom wall 123 of the wiring groove 12 refers to the groove wall that is directly opposite to both the panel 13 and the opening end of the wiring groove 12. A bracket 15 is formed on the side of the lower housing 14 close to the installation cavity 11. The bracket 15 is located on the bottom wall 123 and surrounds the second opening 122, and a slot 151 extending along the opening direction of the second opening 122 is provided on the bracket 15. One end of the slot 151 close to the panel 13 is open, and one end close to the wiring groove 12 is closed. The third circuit board 52 can be inserted from the end of the slot 151 close to the panel 13, so as to be inserted and matched with the slot 151.

[0073] Adopting the method of inserting and matching the bracket 15 and the third circuit board 52 to install the network module 5 improves the installation convenience of the network module 5. In some embodiments of the present application, as Figure 9As shown, at least one of an abutting portion 152 and a first clamping portion 153 is further provided on the bracket 15. When the third circuit board 52 is inserted into the slot 151, the abutting portion 152 abuts against at least a part of the network interface 51, and the first clamping portion 153 clamps with at least a part of the network interface 51 to prevent the third circuit board 52 from coming out of the slot 151, thereby improving the installation reliability of the network module 5 on the lower housing 14.

[0074] For example, referring to Figure 10 , when the network interface 51 includes a SIM card slot 511 and a network cable interface 512, the SIM card slot 511 and the network cable interface 512 are respectively connected to two opposite side surfaces (board surfaces) of the third circuit board 52. When the third circuit board 52 is inserted into the slot 151, the SIM card slot 511 abuts against the abutting portion 152, and the network cable interface 512 clamps with the first clamping portion 153. Therefore, this solution does not require an additional matching structure for the network module 5, but uses the SIM card slot 511 and the network cable interface 512 to achieve positioning and fixing, with a simple and reasonable structure and high space utilization rate.

[0075] In some embodiments of the present application, continue to refer to Figure 9 and Figure 10 , at least a part of the side of the slot 151 close to the second opening 122 is closed, that is, the end of the slot 151 close to the second opening 122 is a closed end 1511. In this way, when the third circuit board 52 is inserted into the slot 151, the third circuit board 52 abuts against the closed end 1511 of the slot 151 to achieve limiting, thereby preventing the network module 5 from coming out reversely from the second opening 122. The bracket 15 further includes a first fixing post 154, and a fastener 155 is installed in the first fixing post 154. Among them, when the third circuit board 52 is inserted into the slot 151, the fastener 155 abuts against the side of the third circuit board 52 away from the second opening 122, thereby preventing the third circuit board 52 from coming out of the slot 151. Therefore, through the closed end 1511 of the slot 151 and the fastener 155, the third circuit board 52 is limited on both sides in the insertion direction of the third circuit board 52, thereby ensuring the reliable installation of the network module 5 on the lower housing 14.

[0076] Optionally, the fastener 155 is a screw with a washer, or the fastener 155 includes a washer and a screw. The third circuit board 52 abuts against the washer of the fastener 155 to be limited.

[0077] In some embodiments of the present application, as Figure 5 shown, at least a part of the first opening 121 is located on the first groove side wall 124 of the wiring groove 12, and the first groove side wall 124 is one of the side groove walls of the wiring groove 12, and the groove side wall is connected between the opening end and the groove bottom wall 123 of the wiring groove 12.

[0078] The circuit board assembly 100 and the terminal 41 can be electrically connected through the first opening 121. As Figure 11 shown, the circuit board assembly 100 (such as the first circuit board 2 mounted on the lower housing 14) is arranged to avoid the wiring groove 12, and the conductive sheet 21 on the circuit board assembly 100 (such as the first circuit board 2) extends into the interior of the wiring groove 12 through the first opening 121. As Figure 12 shown, the housing 411 of the terminal 41 is provided with a limiting hole 4111. As Figure 13 shown, the conductive sheet 21 passes through the limiting hole 4111 and extends into the interior of the terminal 41. Along the opening direction of the wiring groove 12, the conductive sheet 21 is clamped between the edge of the limiting hole 4111 and the edge of the first opening 121. Therefore, the conductive sheet 21 and the terminal 41 are limited and fixed in the opening direction of the wiring groove 12, avoiding the shaking of the terminal 41 in this direction.

[0079] In some embodiments of the present application, as Figure 12 shown, a limiting groove 4112 is further provided on the housing 411 of the terminal 41; as Figure 14 shown, a limiting protrusion 126 is provided on the bottom wall 123 of the wiring groove 12, and the limiting protrusion 126 extends along a direction perpendicular to the first groove side wall 124 of the installation groove. After the terminal 41 is assembled, the limiting protrusion 126 can cooperate with the limiting groove 4112 to limit the position of the terminal 41 in the first direction. Wherein, the first direction is parallel to the wall surface of the first groove side wall 124 and perpendicular to the opening direction of the wiring groove 12.

[0080] Optionally, a part of the first opening 121 is located on the first groove side wall 124 of the installation groove, and the other part is located on the bottom wall 123 of the installation groove. Since the terminal 41 includes a neutral terminal, a ground terminal and a live terminal, the number of the first openings 121 can be three, and the three first openings 121 are arranged at intervals in the second direction, and the limiting protrusion 126 is located between the adjacent first openings 121, so that the space utilization in the wiring groove 12 is more reasonable.

[0081] In some embodiments of the present application, as Figure 14 shown, a second clamping portion 125 is provided inside the wiring groove 12, the terminal 41 abuts against the first groove side wall 124 of the wiring groove 12 and is clamped with the second clamping portion 125 in the second direction, wherein the second direction is perpendicular to the wall surface of the first groove side wall 124, so as to limit the position of the terminal 41 in the second direction.

[0082] Optionally, as Figure 15As shown in the figure, the second clamping portion 125 includes two vertical plates 1251 spaced apart in the first direction, and clamping holes 1252 provided on each vertical plate 1251. The wiring terminal 41 is located between the two vertical plates 1251, and clamping blocks 4113 are respectively provided on both sides of the shell portion 411 of the wiring terminal 41 in the first direction, and the clamping blocks 4113 are used for clamping with the clamping holes 1252 on the vertical plates 1251.

[0083] Optionally, the vertical plate 1251 can have a certain elastic deformation ability. When the wiring terminal 41 is located between the two vertical plates 1251, the two vertical plates 1251 undergo elastic deformation to clamp the wiring terminal 41.

[0084] In summary, the solution of the embodiment of the present application realizes the limit fixation of the wiring terminal 41 in the opening direction of the wiring groove 12 through the cooperation of the conductive sheet 21 and the limit hole 4111, realizes the limit fixation of the wiring terminal 41 in the first direction through the cooperation of the limit protrusion 126 and the limit groove 4112, and realizes the limit fixation of the wiring terminal 41 in the second direction through the clamping of the second clamping portion 125 and the wiring terminal 41. Therefore, the limit fixation of the wiring terminal 41 in space is realized, ensuring that the wiring terminal 41 does not shake or shift.

[0085] Optionally, when the wiring terminal 41 is a screw terminal, the wiring terminal 41 can also be fixed on the conductive sheet 21 by tightening the screw, so that the position of the wiring terminal 41 can also be restricted in the opening direction of the wiring groove 12, the first direction and the second direction.

[0086] In some embodiments of the present application, as Figure 5 shown, a first wiring hole 128 and a second wiring hole 129 are penetratingly provided on the second groove side wall 127 of the wiring groove 12. The second groove side wall 127 is opposite to the first groove side wall 124, and the first wiring hole 128 and the second wiring hole 129 are spaced apart from each other in the second direction. The first direction is parallel to the wall surface of the first groove side wall 124 and perpendicular to the opening direction of the wiring groove 12. The first wiring hole 128 is used to allow the network cable to pass through, and the second wiring hole 129 is used to allow the power supply line to pass through. Waterproof joints are installed in both the first wiring hole 128 and the second wiring hole 129 to improve the sealing and waterproof performance of the wiring groove 12. At least part of the first opening 121 is located on the axial direction of the first wiring hole 128, and at least part of the second opening 122 is located on the axial direction of the second wiring hole 129. This can facilitate the connection of the power supply line entering from the first wiring hole 128 to the wiring terminal 41, and the connection of the network cable entering from the second wiring hole 129 to the network interface 51.

[0087] Optionally, since the power supply line includes multiple wires such as a neutral wire, a ground wire, and a live wire, a wire bundling seat (not shown in the figure) can also be provided in the wiring slot 12. The wire bundling seat is located between the first wiring hole 128 and the wiring terminal 41 and is used to neatly arrange and fix the multiple wires in specific positions to prevent the internal wiring in the wiring slot 12 from being messy.
