Description

Technical Field

[0001] The utility model relates to an electric vehicle, in particular to a wiring device on the electric vehicle for realizing electrical connection of some electric control or power-consuming units at the front side of the electric vehicle. Background Art

[0002] Electric vehicles use electricity as their working power, and all electrical units on the electric vehicle generally need to be electrically connected to the controller through wires. There are relatively more electronic controls and electrical units on the front side of the electric vehicle, such as the headlights, left and right turn signals, horns, instruments and other electrical units, as well as the high and low beam switch for the headlights, the corresponding switches for various lights, the throttle speed control mechanism, the horn control switch, the power control switch, the parking control and other electronic controls. There are also some communication signal lines for vehicle speed, battery power, parking safety, etc. All of these usually require wires to achieve electrical connections between the corresponding structures. When wiring existing electric vehicles, most of them use connectors to electrically connect the controller to the wires on the corresponding structure, that is, the outer end of the wiring harness electrically connected to the electric vehicle controller is arranged at the front side of the electric vehicle, and the electrical connection between the wires on the corresponding structure and the corresponding wires in the wiring harness is achieved through connectors. The relevant wire ends in the wiring harness are arranged in groups. The wire ends in each group are electrically connected to a plug connector. The corresponding electronic control or power-consuming unit is electrically connected to a socket via the wires. The plug connector mates with the socket to electrically connect the power-consuming unit, electronic control, and communication lines to the controller. This electrical connection method results in cluttered wiring on the front of the electric vehicle and inconvenient connection between the plug connector and socket. The plug connector is suspended in the air, and the electrical connection stability of the plug connector is also poor.

[0003] A Chinese patent document (publication number: CN 220527222U) discloses an electric vehicle controller electrical connection harness, belonging to the field of electric vehicle controllers. The utility model includes a controller body, an electrical connection seat, cables, and an electrical connector. The electrical connection seat is provided on one side of the controller body, and multiple cables are provided on the controller body. One end of the cable is provided inside the controller body, and the other end of the cable passes through a wire hole in the electrical connection seat and is electrically connected to the electrical connector. The electrical connector is provided inside a fixed component, and the fixed component is used to fix and classify the electrical connector. The utility model solves the problem of inconvenience in quickly connecting cables in the prior art. The electrical connector is provided inside the fixed component, and there are multiple fixed components. Different cables can be classified by using the fixed component, and the electrical connectors of the same type of cables can be placed in the same fixed component. When wiring, the required electrical connector can be quickly found, the electrical connection of the cables can be completed, and the installation efficiency of the electric vehicle controller is improved.

[0004] This wiring harness classifies different cables, but on the front side of the electric vehicle, it is still necessary to use connectors to achieve electrical connection with the corresponding electrical units, electronic controls and controllers. This will also result in the same wiring problems as existing electric vehicles, making wiring on the front side of the electric vehicle inconvenient and the electrical connection stability of the connectors poor. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a front wiring device for an electric vehicle, which facilitates the electrical connection of corresponding wires and has good electrical connection stability.

[0006] In order to solve the technical problems, the technical solution of the present invention is: a front wiring device for an electric vehicle, comprising a plurality of plug connectors and sockets for correspondingly plugging together, the plug connectors and sockets are both connected to wires, and is characterized in that a fixed mounting platform is provided on the front end side of the electric vehicle, a circuit board is provided on the mounting platform, the sockets are electrically connected and fixed on the circuit board, the sockets comprise a main socket and a plurality of auxiliary sockets, the main socket is electrically connected to the auxiliary sockets through wiring on the circuit board; the main socket is electrically connected to the controller through the main plug connector and the main cable, and the auxiliary sockets are electrically connected to the power consumption unit and the electric control group provided at the front end of the electric vehicle through the auxiliary plug connector and the wires.

[0007] The circuit board is not directly exposed on the electric vehicle, but requires a shielding structure to protect it from rain or dust. This shielding structure can be the instrument described below, or it can be the exterior trim of the electric vehicle. Therefore, the mounting platform can be formed on the instrument, or it can be installed on the front faucet of the electric vehicle via a fixed plate, or at a suitable location on the inside of the exterior trim. The circuit board is prefabricated, and the wiring on the circuit board can achieve corresponding electrical connections between each secondary socket and the main socket. This can be based on the functional control requirements between each power-consuming unit and the electronic control and controller on the electric vehicle.

[0008] Furthermore, the mounting platform is formed on the underside of the electric vehicle's instrument panel. Positioning the mounting platform on the underside of the instrument panel effectively shields the plug connector and socket, preventing rainwater from accumulating on the connector and socket. The socket's integration on the underside of the instrument panel provides ample space for plugging and unplugging, making it easier to connect the connector to the socket.

[0009] Furthermore, the meter protrudes toward the front of the electric vehicle, and the mounting platform is formed on the lower side of the protruding portion of the meter, which facilitates the plug-in connection between the plug connector and the socket, and facilitates the assembly of the electric vehicle and the subsequent maintenance of the circuit.

[0010] Furthermore, the instrument is mounted on a mounting base, and the circuit board is connected to the mounting base. The mounting base is used to mount and fix the instrument, and the circuit board uses the mounting base as an installation base, so the circuit board has good stability.

[0011] Furthermore, the circuit boards are two, arranged in parallel, with the instrument PCB on the upper side and the integrated wiring board on the lower side. The socket is connected to the lower surface of the integrated wiring board, achieving electrical connection between the instrument PCB and the integrated wiring board. The two circuit boards can adapt to different wiring requirements, making wiring simple and easy to assemble.

[0012] Furthermore, an upper socket is connected to the upper surface of the integrated wiring board, and the instrument PCB is electrically connected to the wires and the upper plug connector, which is plugged into the upper socket. The two circuit boards are split, which facilitates installation and also makes wiring between the two circuit boards quick and easy.

[0013] Furthermore, the integrated wiring board is T-shaped, and the main socket is fixed to the small end of the integrated wiring board. This arrangement is reasonable and convenient for arranging the socket on the integrated wiring board.

[0014] Furthermore, the controller is mounted on the rear end of the electric vehicle, and the main cable is extended and fixed to the frame of the electric vehicle. The main cable can be customized according to actual needs, and the connection between the main cable and the frame is stable, and the electrical connection between the electric vehicle controller and the electronic control and power consumption units is stable.

[0015] Compared with the prior art, the present invention has the following beneficial effects: by integrating all the sockets on the electric vehicle on a fixed mounting platform, the mounting platform itself has good positional stability, which makes the sockets stable, facilitates the plug-in connection between the plug connectors and the sockets, and simplifies the wiring of the front end of the electric vehicle. Through the provision of a circuit board, the corresponding electrical connection between the sockets can be effectively achieved, making preparation very convenient, facilitating mass production, and effectively reducing production costs. When wiring, only the corresponding plug connector and socket need to be plugged in, making wiring convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS
