Description

Technical Field

[0001] This utility model relates to the field of vehicle control technology, and in particular to a multifunctional intelligent wiring harness for electric bicycles. Background Technology

[0002] As electric vehicles develop and their functions become more and more sophisticated, they not only require power lines to transmit power, but also require more and more control over the vehicles.

[0003] Typically, electric vehicle batteries serve as the energy source, and through components such as controllers and motors, electrical energy is converted into mechanical energy to move the vehicle, thereby controlling the speed of the vehicle by adjusting the current. However, with the increasing functional requirements, the wiring harness needs to transmit more and more data. Existing technologies generally use network bridges to transfer data through single-port RAM, which requires frequent data copying, resulting in low processing efficiency, as exemplified by the typical prior art disclosed in US5,130,981.

[0004] Some vehicles use in-vehicle Ethernet for high-bandwidth data transmission; however, this type of transmission lacks a time synchronization mechanism for the vehicle, making it difficult to guarantee real-time communication.

[0005] In addition, as electric bicycles become increasingly functional, such as existing electric bicycles that can not only achieve power drive, but also realize LED light information transmission, horn, fingerprint control device, instrument information and other devices, if the wiring harness transmits data separately, the probability of error will increase, as well as the problems of insufficient anti-interference ability and insufficient protocol compatibility.

[0006] Based on the aforementioned problems in the existing technology, this utility model proposes a multifunctional intelligent wire harness. This wire harness can solve the problem of overly complex wire harness structures in the existing technology, as well as reduce the probability of errors, improve anti-interference capabilities, and enhance protocol compatibility.

[0009] Optionally, a power supply line, a CAN data line, a low-voltage power supply line, an adjustable switch line, and a ground wire are connected between the first node and the second node.

[0011] Optionally, the power supply line is a 48V power supply line, the low-voltage power supply line is a 12V power supply line, and the adjustable switch line is an SW-ADJ line.

[0012] Optionally, the first node is connected to the front wheel speed interface via F-PWM and 12V low-voltage power supply lines, and the first node is connected to the second headlight and horn interface via SP+, GND, and D-LED lines.

[0013] Optionally, the multiple interfaces connected to the second node include one or more of the following: a rear taillight radar interface and a rear wheel speed interface.

[0014] Optionally, one or more of the first headlight interface, horn switch interface, left brake interface, instrument interface, and USB interface are connected to the first node via a left contact; one or more of the fingerprint lock interface, ignition lock interface, right brake interface, and throttle interface are connected to the first node via a right contact.
