Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0028] Please also refer to Figure 1 The electric vehicle provided by the present invention will now be described. The electric vehicle includes a vehicle body (not shown), a vehicle controller 10, an integrated controller 20, a battery pack 30, an instrument panel 40, a remote control key 50, a motor 60, a power plug 70, and a plurality of functional components 80. The vehicle controller 10, the integrated controller 20, the battery pack 30, the instrument panel 40, the remote control key 50, the motor 60, the power plug 70, and the plurality of functional components 80 are all disposed on the vehicle body. The integrated controller 20 is composed of the electric vehicle's battery management system 21, the motor controller 22, and the onboard charger 23. The input end of the integrated controller 20 is electrically connected to the battery pack 30, and the output end of the integrated controller 20 is electrically connected to the vehicle controller 10, the motor 60, and the power plug 70. The vehicle controller 10 is electrically connected to and controls the instrument panel 40, the remote control key 50, and the various functional components 80.

[0029] The electric vehicle provided by the present invention is compared with the prior art. The electric vehicle provided by the present invention is provided with a vehicle controller 10 and an integrated controller 20. The integrated controller 20 is composed of the battery management system 21, the motor controller 22 and the on-board charger 23 of the electric vehicle. The vehicle controller 10 is electrically connected to the integrated controller 20, the instrument panel 40, the remote control key 50 and each functional component 80. In this way, the electric vehicle is divided and assembled into five subsystems, namely the vehicle controller 10, the integrated controller 20, the battery pack 30, the instrument panel 40 and the remote control key 50, and multiple functional components 80, thereby making the whole vehicle modularly designed and easy to disassemble, manage and repair. In addition, the vehicle controller 10 controls the integrated controller 20, the instrument panel 40, the remote control key 50 and each functional component 80 separately, so that the subsystems and functional components 80 are independent of each other. If a component is damaged, only the damaged component needs to be replaced without affecting the use of other components, thereby improving the overall safety of the electric vehicle.

[0030] Further, see Figure 1 In a specific embodiment of the electric vehicle provided by the present invention, the integrated controller 20, instrument panel 40, remote control key 50, and various functional components 80 are all electrically connected to the vehicle controller 10 via a single control wiring harness 90. This means that the control wiring harnesses 90 for the integrated controller 20, instrument panel 40, remote control key 50, and various functional components 80 are independent of each other. The vehicle controller 10 directly controls each subsystem and functional component 80, thereby achieving centralized control. This facilitates the design, management, and maintenance of the electric vehicle, improving its safety and after-sales service. Furthermore, the design of a single control wiring harness 90 significantly reduces the number of wiring harnesses, simplifies vehicle wiring, prevents wiring harness aging, and increases the service life of the electric vehicle.

[0031] Furthermore, as a specific embodiment of the electric vehicle provided by the present invention, the above-mentioned vehicle controller 10, integrated controller 20, battery pack 30, instrument panel 40 and remote control key 50 are all provided with independent QR codes for identity identification (not shown in the figure). This embodiment enables each subsystem to have a unique identity for matching, and monitors it through the platform, which cannot be used indiscriminately. Even if it is stolen by a thief, it cannot be charged, thereby achieving an anti-theft effect.

[0032] Further, see Figure 1As a specific embodiment of the electric vehicle provided by the present invention, the above-mentioned motor 60, battery pack 30, integrated controller 20, vehicle controller 10 and instrument panel 40 are arranged in sequence from the rear end to the front end of the electric vehicle. In this way, the subsystems are arranged in an orderly and neat manner on the body of the electric vehicle. At the same time, the integrated controller 20 is electrically connected to the battery pack 30 and motor 60 located at its rear end, and the vehicle controller 10 is electrically connected to the integrated control and instrument panel 40 located near its periphery, so that each control harness 90 is shortened to the minimum, preventing the control harness 90 from interfering with each other, thereby making the wiring of the entire vehicle neat, avoiding harness aging, and extending the service life of the electric vehicle.

[0033] Further, see Figure 1 In a specific embodiment of the electric vehicle provided by the present invention, the functional components 80 include turn signals 81, headlights 82, taillights 83, brakes 84, seat 85, wheel speedometers 86, and a lock 87. The taillights 83 are located at the rear end of the electric vehicle, while the turn signals 81, headlights 82, brakes 84, seat 85, wheel speedometers 86, and locks 87 are all located near the front end of the electric vehicle. This allows all functional components 80, except the taillights 83, to be located near the vehicle controller 10. This minimizes the length of the control wiring harness 90 and prevents interference between the control wiring harnesses 90. This ensures neat wiring throughout the vehicle, prevents wiring harness aging, and increases the lifespan of the electric vehicle.

[0034] Further, see Figures 2 to 4As a specific embodiment of the electric vehicle provided by the present invention, the above-mentioned vehicle controller 10 includes a shell 11, a circuit board 12, a first socket 13, a second socket 14, a first wire holder 15 and a second wire holder 16. The circuit board 12 is arranged in the shell 11, the first socket 13 and the second socket 14 are arranged on the circuit board 12 and are electrically connected to the circuit board 12, the first wire holder 15 is arranged on the shell 11 and is used for the first control wire harness 91 connected to the first socket 13 to pass through, and the second wire holder 16 is arranged on the shell 11 and is used for the second control wire harness 92 connected to the second socket 14 to pass through. During installation, the vehicle controller 10 in this embodiment is first manufactured by manufacturing a circuit board 12, and then the first socket 13 and the second socket 14 are arranged on the circuit board 12 by welding or plugging. The first socket 13 is then connected to the first control harness 91, and the second socket 14 is connected to the second control harness 92. Finally, the first control harness 91 is passed through the first wire holder 15 and connected to a part of the integrated controller 20, the battery pack 30, the instrument panel 40, the remote control key 50, the motor 60, the power plug 70 and multiple functional components 80, and the second control harness 92 is passed through the second wire holder 16 and connected to another part of the integrated controller 20, the battery pack 30, the instrument panel 40, the remote control key 50, the motor 60, the power plug 70 and multiple functional components 80. In this embodiment, by providing the first socket 13, the second socket 14, the first wire holder 15 and the second wire holder 16, the cables connecting the vehicle controller 10 and the external circuit are concentrated at the first wire holder 15 and the second wire holder 16, thereby making the cable layout of the vehicle controller 10 neat and tidy, making the cable layout of the entire electric vehicle neat and preventing cable aging.

[0035] In this example, see Figure 4 The circuit board 12 is provided with two first sockets 13, and the first control harnesses 91 connected to the two first sockets 13 pass through the first wire holder 15. Of course, in other embodiments of the present invention, depending on the number and control requirements of the external subsystems and functional components 80, the circuit board 12 may be provided with multiple first sockets 13 and multiple second sockets 14, or only with the first socket 13 and the first wire holder 15. This is not intended to be a limitation here.

[0036] In this example, see Figures 2 to 4 The first and second wire holders 15, 16 are symmetrically arranged on opposite sides of the housing 11. Specifically, the first wire holder 15 is arranged on the side of the housing 11 near the rear end of the electric vehicle, and the second wire holder 16 is arranged on the side of the housing 11 near the front end of the electric vehicle, thereby making the wiring harness layout of the entire vehicle neat. Of course, in other embodiments of the present invention, according to actual conditions and specific requirements, one or more wire holders may also be provided on the housing 11, and the wire holders may be allocated according to actual conditions, and this is not a sole limitation here.

[0037] In this embodiment, the first and second wire holders 15 and 16 have similar structures and are installed on the housing 11 in the same manner. The following description will focus on the installation of the first wire holder 15 on the housing 11 .

[0038] In this embodiment, the first wire holder 15 is provided with a plurality of wire grooves (not shown in the figure). The wire grooves are circular and run through the entire first wire holder 15. The wire grooves extend from the inside of the housing 11 to the outside of the housing 11. The wire grooves are used for passing the first control wire harness 91. Figure 6 The first wire holder 15 has a first side 152 and a second side 153 oppositely disposed. The first side 152 is located inside the housing 11 , and the second side 153 is located outside the housing 11 . The wire groove extends vertically from the first side 152 to the second side 153 .

[0039] Specifically, in this embodiment, a waterproof rubber bag (not shown) is further provided in the wire duct, and the first control wire harness 91 passes through the waterproof rubber bag, thereby preventing water from entering the interior of the housing 11 and preventing the electrical components inside the housing 11 from getting damp.

[0040] In this example, see Figure 5 and Figure 6 The shell 11 is provided with a mounting groove, and the first wire seat 15 is provided with a card slot 150 extending along its circumference. The card slot 150 is clamped on the edge of the mounting groove and connected through a sealing ring 113. The design of the sealing ring 113 makes the connection between the first wire seat 15 and the shell 11 highly sealed, preventing water from entering the shell 11 from the connection between the first wire seat 15 and the shell 11, thereby improving the waterproof effect of the entire shell 11.

[0041] For more details, please refer to Figure 3 As a specific embodiment of the integrated controller 20 provided by the present invention, the above-mentioned shell 11 includes a bottom shell 111 and an upper cover 112. The edge of the upper cover 112 is abutted against the edge of the bottom shell 111 and is sealed by a sealing ring 113. The upper cover 112 and the bottom shell 111 are enclosed to form an installation cavity 110. The circuit board 12, the first socket 13 and the second socket 14 are all arranged in the installation cavity 110, and the first wire holder 15 and the second wire holder 16 are arranged on the bottom shell 111.

[0042] Further, see Figure 5 As a specific embodiment of the integrated controller 20 provided by the present invention, the bottom shell 111 is provided with a U-shaped groove 1110 opening toward the upper cover 112, wherein the U-shaped groove 1110 and the edge of the upper cover 112 enclose the above-mentioned installation groove, see Figure 4 and Figure 6 The card slot 150 is clamped on the edge of the U-shaped groove 1110 and the edge of the upper cover 112.

[0043] Further, in this embodiment, please refer to Figure 5 and Figure 6 The bottom shell 111 has a first receiving groove 1111 defined on its edge, and the first cable holder 15 has a second receiving groove 151 defined on its edge. The second receiving groove 151 is located at the bottom of the latching slot 150 and communicates with the latching slot 150. The second receiving groove 151 communicates with the first receiving groove 1111 along the circumference of the bottom shell 111. The sealing ring 113 extends through the first and second receiving grooves 1111 and 151. During installation, the first cable holder 15 is first secured to the U-shaped groove 1110, the sealing ring 113 is then positioned in the first and second receiving grooves 1111 and 151, and the top cover 112 is inserted into the first and second receiving grooves 1111 and 151, ensuring that the top cover 112 abuts the sealing ring 113. Finally, the assembly is secured using fasteners.

[0044] See also Figure 3 and Figure 4 Both the upper cover 112 and the bottom shell 111 are provided with a baffle 114. The baffle 114 extends vertically downward from the top of the upper cover 112, or vertically upward from the bottom of the bottom shell 111. The baffle 114 is located inside the first wire holder 15 and is used to limit the position of the first wire holder 15. Specifically, the upper cover 112 is provided with two baffles 114, which are arranged in parallel in a horizontal direction, thereby facilitating the installation of the first wire holder 15 and achieving a certain limiting effect on the first wire holder 15.

[0045] Preferably, as a specific embodiment of the electric motor provided by the present invention, the housing 11 is made of aluminum, and the first and second cable holders 15, 16 are both made of a soft material. This embodiment utilizes a combination of soft and hard materials to ensure a tighter fit of the first and second cable holders 15, 16 on the housing 11, thereby enhancing the waterproofing of the vehicle controller 10. Furthermore, the housing 11 is made of aluminum, which has excellent heat dissipation properties, thereby enhancing heat dissipation within the housing 11.

[0046] Further, see Figure 2 and Figure 4 As a specific embodiment of the electric vehicle provided by the present invention, the housing 11 is provided with a clip 1112 on the inner side. The edge of the circuit board 12 is clipped onto the clip 1112. Thus, during installation, the circuit board 12 only needs to be easily snapped into the clip 1112. This is simple to operate and saves screw costs and installation process. Specifically, the clip 1112 is provided on the bottom shell 111. There are four clips 1112 distributed on the bottom shell 111, which stably clip the circuit board 12 to the bottom shell 111.

[0047] Furthermore, as a specific embodiment of the electric vehicle provided by the present invention, the housing 11 is also provided with a pressure relief valve (not shown). The pressure relief valve is used to discharge heat and gas from the housing 11 when excessive heat or increased pressure occurs inside the housing 11, thereby maintaining heat and pressure balance within the housing 11, preventing explosion of the housing 11, and improving the service life of the vehicle controller 10. Specifically, in this embodiment, the pressure relief valve is provided on the upper cover 112. Of course, in other embodiments of the present invention, the pressure relief valve may also be provided on the bottom housing 111, and this is not intended to be a limitation here.
