[0036] The specific embodiments of the present application will be further described in detail below in connection with the drawings and embodiments. The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

[0037] AsFigure 1 As shown, Figure 1 is a structural diagram of a current terminal structure in the prior art;

[0038] As Figure 1 and Figure 2 The current terminal structure in the prior art has the following problems,

[0039] (1) The current terminal is a long straight copper column 200, and when using the wave soldering process, since the copper column 200 of the current terminal structure is too high, after being welded on the PCB board 100, it is extremely unstable and is prone to skewing, which affects welding, leading to unstable welding or virtual welding, and causing the current terminal structure to malfunction.

[0040] (2) The current terminal is a long straight copper column 200, and it is not easy to position, and after the position is skewed and deviated, it will eventually affect the cooperation with other parts, such as the sealing structure, and shorten the service life of the sealing structure.

[0041] (3) Since the current terminal of the controller needs to pass a large current, the installation (screw fixation) of the external wiring is subjected to a large torque, and the current terminal used in the prior art is a long cylindrical body, which will directly transmit the torque to the PCB board 100, easily damaging the solder joint at the root of the current terminal, shortening the service life of the solder joint, and causing the controller to malfunction.

[0042] As Figures 3-5 shown, the embodiment provides a current terminal structure,

[0043] The current terminal structure comprises:

[0044] a conductive sheet 300;

[0045] a copper column 200 connected to the PCB board 100 through the conductive sheet 300;

[0046] and a bracket 400 in contact with the conductive sheet 300 and located below the copper column 200, for limiting the conductive sheet 300.

[0047] The PCB board 100 is a circuit board of the controller, and the PCB board 100 is provided with a plurality of circuits.

[0048] The conductive sheet 300 of the embodiment is a copper sheet, and the copper sheet is formed by stamping.

[0049] The copper column 200 is a long column type, wherein the copper column 200 is a machined part.

[0050] The copper column 200 and the conductive sheet 300 form a current terminal, specifically, the copper column 200 and the conductive sheet 300 are integrated by adopting a brazing process.

[0051] The copper column 200 is connected with the PCB 100 through the conductive sheet 300, and the bottom of the bracket 400 is in contact with the PCB 100.

[0052] The copper column 200 is connected with the PCB 100 through the conductive sheet 300, and the copper column 200 is inserted with an external device line, and the conductive sheet 300 can be powered and communicated.

[0053] The current terminal is formed by combining the conductive sheet 300 and the copper column 200, and the bracket 400 limits the current terminal to prevent the current terminal from being skewed or deviated during welding, so that the current terminal is easy to weld, the welding quality and uniformity are ensured, the welding quality is effectively improved, and when the torque is transmitted from the copper column 200 to the conductive sheet 300 during plugging and unplugging of the copper column, the conductive sheet 300 is slightly deformed, the conductive sheet 300 is pressed against the bracket 400 due to the limiting of the bracket 400 on the conductive sheet 300, and the bracket 400 bears part of the torque, so that the solder joint between the foot of the conductive sheet 300 and the PCB is not pulled off under the action of the torque, and the problem of shortening the welding life is avoided. Further, the technical problem that the current terminal structure is unstable after being welded on the PCB 100 due to the too high copper column 200 of the current terminal structure, and is easy to be skewed to affect welding, resulting in unstable welding or virtual welding and causing failure of the current terminal structure is effectively solved.

[0054] Specifically, both feet of the conductive sheet 300 are connected with the PCB 100, the copper column 200 is arranged at the middle of the conductive sheet 300, and at least one side surface of the conductive sheet 300 is in contact with the side surface of the bracket 400.

[0055] The bracket 400 is an injection molded part, which is bolted, screwed or directly injection molded on the PCB 100, and the bracket 400 can position the conductive sheet 300 and the copper column 200 to ensure the accurate assembly position of the current terminal.

[0056] The two feet of the conductive sheet 300 are connected to the PCB board 100, specifically, the two feet of the conductive sheet 300 are welded on the PCB board 100. When welding of one foot of any conductive sheet 300 is unstable or false, the other foot can ensure that the conductive sheet 300 can maintain good current and communication functions, avoiding the failure of the current terminal structure.

[0057] Especially, when the width of the bracket is greater than the width of the conductive sheet, the torque received by the conductive sheet can be better absorbed by the bracket, thereby better protecting the welding point between the conductive sheet and the PCB board.

[0058] The two feet of the conductive sheet 300 are bent towards the PCB board 100, and the middle part has a middle part 310 for installing the copper column 200, and the bracket 400 is located between the two feet of the conductive sheet 300. The copper column 200 is welded on the middle part 310, specifically, the middle part 310 has a mounting hole, the bottom of the copper column 200 has a mounting part 201, the mounting part 201 is inserted into the mounting hole and fixed by welding. Thus, the copper column 200 can be more stably fixed on the conductive sheet 300, improving the welding space and welding strength. The structure of the mounting part 201 is a columnar structure extending downward, and the cross-sectional area is smaller than the cross-sectional area of the copper column 200.

[0059] Among them, at least two welding points are arranged between any foot of the conductive sheet 300 and the PCB board 100. In this embodiment, one foot of the conductive sheet 300 has two welding points, which can continue to work for power supply or communication when false welding or unstable welding occurs at any welding point, improving the stability of the current terminal structure.

[0060] The bottom of the bracket is in contact with the PCB board, and the structure avoids the elements of the PCB board. When the bracket encounters the elements of the PCB board, it can be arranged around the corresponding elements, so that the bracket can more reasonably use the surface of the PCB board without affecting the surface of the PCB board.

[0061] The top of the bracket 400 is provided with an avoiding groove, and the bottom of the mounting part 201 is placed in the avoiding groove through the mounting hole. So that the mounting part of the copper column 200 can pass through the mounting hole without affecting the contact between the conductive part 300 and the bracket 400.

[0062] In order to make the conductive sheet 300 and the PCB board 100 have greater stability, avoid damaging the welding point between the conductive sheet 300 and the PCB board 100 under external force, the two side surfaces and the upper surface of the bracket 400 are in contact with the conductive sheet 300. The bracket 400 can limit the conductive sheet 300, the bracket 400 can be close to the conductive sheet 300, share part of the force, achieve the effect of protecting the welding point, thereby avoiding the problem of damaging the welding point between the conductive sheet 300 and the PCB board 100 when subjected to torque.

[0063] The welding in the above is all carried out by using a wave soldering process.

[0064] The conductive sheet 300 and the copper column 200 are both multiple, the conductive sheet 300 is connected with the copper column 200 one by one, and the bracket 400 passes between the two feet of each conductive sheet 300. The conductive sheet 300 and the copper column 200 in the embodiment are five, installed through the same bracket 400, the bracket 400 passes between the two feet of each conductive piece, and the middle part 310 is located above the bracket 400, so that the current terminal structure can be stably arranged on the PCB board 100, and the bracket 400 can play a limiting role, ensuring that each current terminal is accurately configured to the required position; meanwhile, when any copper column needs to be plugged, torque acts on the corresponding conductive sheet, the conductive sheet is slightly deformed, and since the bracket limits the conductive sheet, the conductive sheet extrudes the bracket, at this time, the bracket bears part of the torque and transmits the force to other terminals, thereby reducing the pressure borne by the conductive sheet, thereby achieving the effect of protecting the welding point between the conductive sheet and the PCB board.

[0065] The embodiment of the application also provides a controller, characterized in that the controller comprises a PCB board and a current terminal structure as described above mounted on the PCB board.

[0066] The controller can effectively solve the technical problem in the current terminal structure of the prior art that since the copper column 200 of the current terminal structure is too high, after being welded on the PCB board 100, the current terminal structure is extremely unstable and is prone to skewing, thereby affecting welding, leading to unstable welding or virtual welding, and causing the current terminal structure to malfunction.

[0067] The current terminal structure further comprises a shell, the PCB board 100 is mounted on the shell, and the shell is used for protecting the PCB board 100 and the current terminal, thereby avoiding the problem that the PCB board 100 and the current terminal are damaged under external force impact. The shell is an aluminum alloy metal shell, which has small mass and low cost.

[0068] The application also provides a motorcycle comprising the controller as described above.

[0069] The motorcycle can effectively solve the technical problem that the copper column of the current terminal structure is too high, and after being welded on the PCB, the current terminal structure is extremely unstable and is easily skewed, which affects welding, causes unstable welding or virtual welding, and causes the current terminal structure to malfunction.

[0070] The application is suitable for vehicles including pure electric or hybrid vehicles, and specifically includes electric motorcycles, electric mopeds and electric (power-assisted) bicycles. It is mainly used on electric motorcycles, but other vehicles driven by motors and having controllers can also improve the reliability of the controller terminal with the application.

[0071] The above-described embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements for some technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
