Description

Technical Field

[0001] This utility model relates to an electric wheelchair, and more particularly to a simplified electric wheelchair driving light wiring harness electrical device used for vehicle indication on an electric wheelchair. Background Technology

[0002] Electric wheelchairs or mobility scooters generally refer to transportation or assistive devices designed for mobility purposes. They are typically small cars, electric bicycles, electric mobility scooters, and electric wheelchairs used to replace human walking, meeting the needs of people with good mobility for longer distances or those with mobility impairments, thereby improving efficiency in travel and errands. Currently, some electric wheelchairs or mobility scooters lack a dedicated taillight mounting point, resulting in the absence of running lights. Alternatively, modifications to the controller's output mounting point are required to add running lights, but this leads to significant overall modifications and may not be feasible for electric wheelchairs or mobility scooters without a built-in taillight mounting point to include running lights. Utility Model Content

[0003] This utility model addresses the current situation where existing electric wheelchairs or mobility scooters lack a dedicated taillight function foothold, resulting in the absence of a driving light function, or require modifications to the controller's output foothold function to achieve a driving light function. However, such modifications lead to significant overall changes and fail to adequately accommodate driving light functionality in electric wheelchairs or mobility scooters that lack a taillight function foothold controller. The present invention provides a simplified driving light wiring harness electrical device for electric wheelchairs that provides driving light indication for electric wheelchairs or mobility scooters without altering the number of terminals occupied by the original controller's output foothold, thus saving space in the controller's output foothold design.

[0004] The specific technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a simplified electric wheelchair driving light wiring harness electrical device, including an electric wheelchair controller and a motor brake. Pin 4 of the CN4 connector of the controller U1 is the positive terminal for controller-controlled brake, and pin 8 is the negative terminal for controller-controlled brake. It also includes a fourth connector, a fifth connector, a power cord assembly, and a driving light. The power cord assembly has a positive power cord and a negative power cord. The fourth connector and the fifth connector are electrically connected to the positive and negative terminals of the CN4 connector of the controller U1 via the power cord assembly, respectively. The positive and negative terminals of the plug-in output terminals of the fifth connector are electrically connected to the motor brake, and the positive and negative terminals of the plug-in output terminals of the fourth connector are electrically connected to the positive and negative terminals of the driving light, respectively. By leading out the positive and negative terminals of the controller brake control pin on the CN4 connector of the controller U1 through the power cable group, and connecting them to the power supply and control of the driving lights of the motor brake through the 4th and 5th connectors, the driving lights can be controlled to be lit. This not only provides driving light indication function for electric wheelchairs or mobility scooters, but also saves the number of controller output pin terminals occupied, which is conducive to improving the terminal function expansion application of the electric wheelchair or mobility scooter controller.

[0005] Preferably, the fourth connector includes a fourth plug-in first input terminal, a fourth plug-in second input terminal, a fourth plug-in third output terminal, and a fourth plug-in fourth output terminal. The fourth plug-in first input terminal is electrically connected to pin 4 of the CN4 connector of the controller U1, which is the positive terminal for controlling the brake. The fourth plug-in second input terminal is electrically connected to the negative terminal for controlling the brake of the CN4 connector of the controller U1. The fourth plug-in third output terminal is electrically connected to the first terminal of the coil in the motor brake, and the fourth plug-in fourth output terminal is electrically connected to the second terminal of the coil in the motor brake. This improves the convenience, flexibility, simplicity, and effectiveness of power supply, installation, connection, maintenance, and disassembly.

[0006] Preferably, the fifth connector includes a fifth connector first input terminal, a fifth connector second input terminal, a fifth connector third output terminal, and a fifth connector fourth output terminal. The fifth connector first input terminal is electrically connected to the controller control brake negative terminal of the CN4 connector of the controller U1; the fifth connector second input terminal is electrically connected to pin 4 of the CN4 connector of the controller U1, which is the controller control brake positive terminal; the fifth connector third output terminal is electrically connected to the negative terminal of the driving light; and the fifth connector fourth output terminal is electrically connected to the positive terminal of the driving light. This improves the convenience, flexibility, simplicity, and effectiveness of power supply, installation, connection, maintenance, and disassembly.

[0007] The beneficial effects of this utility model are as follows: the positive and negative terminals of the controller control brake of the CN4 connector of the controller U1 are led out through the power cable group and the power supply and control of the driving light of the motor brake are realized through the 4th and 5th connectors, so as to realize the control and lighting of the driving light; it can provide driving light indication function for electric wheelchairs or mobility scooters, and does not require changing the number of terminals occupied by the controller output pins, which helps to save the design space of the controller output pins. The wiring harness electrical device is simple and durable in design and has good after-sales maintainability. Attached Figure Description
