[0002] Electric vehicles, as a type of new energy vehicle, have advantages such as energy saving and simple maintenance, and can replace traditional vehicles to solve energy shortages and environmental pollution problems. In daily life, the application of electric vehicles is becoming increasingly widespread, and the charging equipment, such as charging guns, used in conjunction with them is also developing rapidly.

[0003] Charging guns are mainly used to charge electric vehicles. The charging gun contains components such as PCB boards, signal lines, and power lines, which makes the internal wiring layout relatively complicated and prone to wire crossing. In addition, as the functions of the charging gun increase, different functional modules are integrated into the charging gun, making the overall size of the charging gun larger. Utility Model Content

[0006] The bracket has mounting cavities and multiple mounting slots along its length.

[0007] Signal wires and power wires are installed in corresponding mounting slots, with both ends of the signal wires extending out of the corresponding mounting slots and both ends of the power wires extending out of the corresponding mounting slots. The two ends of the signal wires are respectively the first signal terminal and the second signal terminal, and the two ends of the power wires are respectively the first power terminal and the second power terminal.

[0008] The PCB assembly is installed inside the mounting cavity, and both the signal line and the power line are electrically connected to the PCB assembly.

[0009] In the aforementioned integrated bracket, both the first signal terminal and the second signal terminal are short metal rods, and they are connected by a wire; both the first power terminal and the second power terminal are short metal rods, and they are connected by a wire; or the signal line and power line are long metal rods.

[0010] In the aforementioned integrated bracket, the plane where the cavity opening of the mounting cavity is located is recessed to form a stepped plane, and multiple connecting parts are provided on the stepped plane. The connecting parts are connected to the PCB board assembly to fix the PCB board assembly on the bracket. A positioning part is provided on the bottom of the mounting cavity. When the PCB board assembly is inserted into the mounting cavity, the positioning part limits the degree of freedom of the PCB board assembly in the mounting cavity.

[0011] In the aforementioned integrated bracket, the bracket includes a first mounting part, a second mounting part, and a third mounting part in sequence along its length, and the mounting groove passes through the first mounting part, the second mounting part, and the third mounting part, with the mounting cavity located on the second mounting part.

[0012] In the aforementioned integrated bracket, the first mounting part, the second mounting part, and the third mounting part are integrally formed; or any two of the first mounting part, the second mounting part, and the third mounting part are integrally formed, and the third part is spliced ​​with the other two; or the first mounting part, the second mounting part, and the third mounting part are all separately set and spliced ​​with each other.

[0013] In the aforementioned integrated bracket, a receiving cavity is provided on the second or third mounting part, and a current sensor is provided inside the receiving cavity, wherein the power line passes through the current sensor.

[0014] In the aforementioned integrated bracket, connection terminals are provided at the ends of the first mounting portion and the third mounting portion.

[0015] In the aforementioned integrated bracket, the PCB assembly is a single circuit board or comprises multiple circuit boards. When the PCB assembly comprises multiple circuit boards, they are a first circuit board, a second circuit board, and a third circuit board, with the first circuit board located at the opening of the mounting cavity and the second and third circuit boards inserted into the mounting cavity.

[0016] In the aforementioned integrated bracket, when the PCB board is assembled into multiple circuit boards, the first circuit board, the second circuit board, and the third circuit board are spliced ​​together to form a "π" structure. Alternatively, when the PCB board is assembled into multiple circuit boards, the first circuit board, the second circuit board, and the third circuit board are arranged vertically. The second circuit board and the third circuit board are connected by a plug-in joint, and the first circuit board and the second circuit board are connected by a wire.

[0020] (2) Design the entire signal line or power line as a single metal rod, preferably a copper rod. This not only solves the problems existing in the current technology, but also reduces energy loss and improves heat dissipation.

[0021] (3) By using the recessed stepped plane, the PCB assembly connected to the bracket can be recessed into the bracket. At this time, the structures on both sides of the stepped plane are higher than the stepped plane, thus forming protection for the PCB assembly and improving the reliability of the integrated bracket.

[0022] (4) Connecting terminals are provided at the ends of the first mounting part and the third mounting part. Through the connecting terminals, on the one hand, the wires can be sorted, and on the other hand, the ends of the wires can be set as male or female snaps in metal male and female snaps and fixed on the connecting terminals. The original method of fixing by wire welding is changed to male and female snap plug-in, which improves the reliability of electrical connection and solves the problem of wire tangling.

[0035] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0036] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

[0037] Example 1

[0038] like Figures 1 to 3 As shown, the integrated bracket provided by this utility model includes:

[0039] The bracket 10 has a mounting cavity 11 and multiple mounting grooves 12 along its length, wherein at least one mounting groove 12 passes through the mounting cavity 11.

[0040] Signal line 20 and power line 30 are respectively installed in corresponding mounting slots 12, with both ends of signal line 20 extending out of the corresponding mounting slots 12 and both ends of power line 30 extending out of the corresponding mounting slots 12. The two ends of signal line 20 are respectively the first signal terminal 21 and the second signal terminal 22, and the two ends of power line 30 are respectively the first power terminal 31 and the second power terminal 32.

[0041] The PCB assembly 40 is installed in the mounting cavity 11, and both the signal line 20 and the power line 30 are electrically connected to the PCB assembly 40.

[0042] It is worth mentioning that the first signal terminal 21 on the signal line 20 and the first power terminal 31 on the power line 30 are connected to the connector in the charging gun, and the second signal terminal 22 on the signal line 20 and the second power terminal 32 on the power line 30 are connected to the charging interface on the electric vehicle to realize the charging of the electric vehicle.

[0043] The present invention provides an integrated bracket that integrates signal lines 20, power lines 30, PCB board assembly 40 and their interconnections on the bracket 10, thereby organizing the circuits, avoiding circuit crossings, and reducing the overall size of the integrated bracket, thus reducing the size of the charging gun.

[0044] Furthermore, it is pointed out that the two signal terminals or the two power terminals are connected by soldering wires, and both signal terminals and power terminals are short metal rods. This connection method can save costs. However, this connection method has two drawbacks. First, there is the possibility of poor soldering or weak soldering, which reduces the reliability of signal or energy transmission. Second, since the operation between the charging gun and the electric vehicle charging interface is a plugging and unplugging action, after long-term use, the signal terminals or power terminals are prone to breakage with the wires, affecting the reliability of the charging gun. In this embodiment, the entire signal line 20 or power line 30 is designed as a single long metal rod, preferably a copper rod. This not only solves the problems existing in the prior art, but also reduces energy loss and improves heat dissipation.

[0045] It is worth mentioning that when the current is small, the two signal terminals and the two power terminals are connected by wires, and when the current is large, the entire signal line and power line are made of metal copper rods.

[0046] Preferably, the plane where the cavity opening of the mounting cavity 11 is located is recessed to form a stepped plane 13, and a plurality of connecting parts 14 are provided on the stepped plane 13. The connecting parts 14 are connected to the PCB board assembly 40, and the PCB board assembly 40 is fixed on the bracket 10.

[0047] In this embodiment, the PCB assembly 40 connected to the bracket 10 can be recessed into the bracket 10 by the recessed stepped plane 13. At this time, the structures on both sides of the stepped plane 13 are higher than the stepped plane 13, thereby forming protection for the PCB assembly 40 and improving the reliability of the integrated bracket.

[0048] It is worth mentioning that the connecting part 14 is a connecting post, and multiple connecting posts are distributed on each corner of the plane where the cavity opening of the mounting cavity 11 is located. Each connecting post is provided with a connecting hole, and the connection between the PCB board assembly 40 and the bracket 10 is completed by fasteners.

[0049] Furthermore, a positioning part 15 is provided on the bottom of the mounting cavity 11. When the PCB assembly 40 is inserted into the mounting cavity 11, the positioning part 15 limits the degree of freedom of the PCB assembly 40 within the mounting cavity 11.

[0050] It is worth mentioning that in this embodiment, there are two positioning parts 15, and the two positioning parts 15 are arranged opposite to each other. Each positioning part 15 is provided with a slot, which is engaged with the PCB board assembly 40.

[0051] Preferably, the bracket 10 includes a first mounting portion 16, a second mounting portion 17, and a third mounting portion 18 in sequence along its length, and the mounting groove 12 passes through the first mounting portion 16, the second mounting portion 17, and the third mounting portion 18. The mounting cavity 11 is located on the second mounting portion 17. The first mounting portion 16 is arc-shaped, and the second mounting portion 17 and the third mounting portion 18 are straight.

[0052] It is worth mentioning that the first mounting part 16 is set in an arc shape to match the overall shape of the charging gun. Similarly, the first mounting part 16 can also be set in a straight line. In addition, the first mounting part 16, the second mounting part 17, and the third mounting part 18 are integrally formed; or any two of the first mounting parts 16, the second mounting part 17, and the third mounting part 18 are integrally formed, and the third part is set separately from the other two and connected by fasteners or by a tongue-and-groove fitting; or the first mounting part 16, the second mounting part 17, and the third mounting part 18 are all set separately and connected by fasteners or by a tongue-and-groove fitting.

[0053] It is further pointed out that the bracket 10 serves as the skeleton of the entire integrated bracket, and the bracket 10 is generally formed by injection molding. Its material is plastic, which is lightweight and has good insulation properties.

[0054] Preferably, the PCB assembly 40 includes multiple circuit boards, namely a first circuit board 41, a second circuit board 42 and a third circuit board 43, wherein the first circuit board 41 is located at the cavity opening of the mounting cavity 11, and the second circuit board 42 and the third circuit board 43 are inserted into the mounting cavity 11, wherein the second circuit board 42 and the third circuit board 43 are electrically connected to the first circuit board 41 respectively.

[0055] It is further pointed out that the PCB assembly 40 can be a single circuit board or include multiple circuit boards.

[0056] Furthermore, when the PCB assembly 40 consists of multiple circuit boards, the first circuit board 41, the second circuit board 42, and the third circuit board 43 are spliced ​​together to form a "π" structure. The first circuit board 41 is located at the opening of the mounting cavity 11, and the second circuit board 42 and the third circuit board 43 are inserted into the mounting cavity 11.

[0057] More preferably, the first circuit board 41 is provided with a connecting hole connected to the connecting part 14, and the second circuit board 42 and the third circuit board 43 are provided with a locking block that engages with the positioning part 15. Through the connecting part 14 and the positioning part 15, the PCB assembly 40 is installed and fixed in the mounting cavity 11.

[0058] This utility model also includes a charging gun, which has a metering function. In this case, a receiving cavity 19 is also provided on the bracket 10, and one of the multiple mounting slots 12 passes through the receiving cavity 19 along the length direction of the bracket 10. A current sensor 50 is installed in the receiving cavity 19, and the power line 30 corresponding to the mounting slot 12 passes through the current sensor 50.

[0059] It is further noted that the receiving cavity 19 is located on the third mounting part 18.

[0060] Example 2

[0061] like Figures 4 to 6 As shown, compared with Embodiment 1, the difference between this embodiment and Embodiment 1 is that in Embodiment 1, a stepped plane 13 is provided at the opening of the mounting cavity 11, and a connecting part 14 is provided on the stepped plane 13, and a positioning part 15 is provided at the bottom of the mounting cavity 11; while in this embodiment, a stepped plane 13 is also provided at the opening of the mounting cavity 11, and a connecting part 14 is provided on the stepped plane 13, but a sunken support plane is provided at the bottom of the mounting cavity 11, and a connecting part 14 is provided on one part of the corner of the support plane, and a positioning part 15 is provided on the other part of the corner.

[0062] Furthermore, the connecting part 14 located at the corner of the part is arranged diagonally, and the positioning part 15 located at the corner of the part is also arranged diagonally.

[0063] It is worth mentioning that in this embodiment, the PCB assembly 40 is divided into two circuit boards, one of which is mounted on the stepped plane 13 at the opening of the mounting cavity 11, and the other is mounted on the support plane at the bottom of the mounting cavity 11.

[0064] More preferably, in the embodiment the receiving cavity 19 for mounting the current sensor 50 is located at the position of the third mounting part 18, while in this embodiment the receiving cavity 19 for mounting the current sensor 50 is located at the position of the second mounting part 17.

[0065] More preferably, the integrated bracket in Embodiment 1 is an integrated bracket in an AC charging gun, while the integrated bracket in this embodiment is an integrated bracket in a DC charging gun. The major difference between an AC charging gun and a DC charging gun is that the AC charging gun has relatively fewer wires besides the signal line 20 and power line 30, while the DC charging gun has a relatively larger number of wires besides the signal line 20 and power line 30. This can lead to "tangle" of wires, causing chaotic wire management, increasing maintenance difficulty, and potentially causing short circuits or other electrical faults due to insulation wear. Therefore, to solve this problem, in this embodiment, connecting terminals 60 are provided at the ends of the first mounting part 16 and the third mounting part 18. The connecting terminals 60 allow for wire organization and allow the ends of the wires to be configured as male or female snap-fit ​​connectors, fixing them to the connecting terminals 60. This replaces the original wire welding method with a snap-fit ​​connection, improving electrical connection reliability and solving the tangle problem.

[0066] Preferably, in Embodiment 1, when the PCB assembly consists of multiple pieces, the first circuit board 41, the second circuit board 42, and the third circuit board 43 are spliced ​​to form a "π" structure. The first circuit board 41 is located at the opening of the mounting cavity 11, and the second circuit board 42 and the third circuit board 43 are inserted into the mounting cavity 11. In this embodiment, when the PCB assembly consists of multiple pieces, the first circuit board 41, the second circuit board 42, and the third circuit board 43 are arranged vertically, with the first circuit board 41 located at the opening of the mounting cavity 11 and the third circuit board 43 located at the bottom of the mounting cavity 11. The third circuit board 43 is inserted into and engages with the second circuit board 42.

[0067] It is worth mentioning that the first circuit board 41 is a metering module, the second circuit board 42 is an integrated bracket connection board, and the third circuit board 43 is an external signal adapter board. The signal adapter board is equipped with a micro switch, an electronic lock, and a communication board. The signal lines of the micro switch, electronic lock, and communication board are connected to the third circuit board 43 and are converted through the second circuit board 42. Some of the signal lines are connected to the first circuit board 41, and some are connected to the connector.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly defined. The terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two elements or the interaction between two elements, unless otherwise explicitly defined. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
