[0002] Electric bicycles and electric tricycles are favored by people and recognized by urban traffic management departments for their labor-saving, convenience, economy, and environmental friendliness, and are therefore widely used as people's means of transportation. However, some malfunctions are inevitable during use, such as key switch failure, gear shift failure, accelerator failure, encoder failure, brake power-off switch failure, controller failure, and battery failure.

[0003] In existing technologies, fault detectors with voltmeters are generally used to diagnose and repair faults in electric vehicles, such as key switch failures, gear shift failures, accelerator failures, encoder failures, brake power-off switch non-returning failures, controller failures, and battery failures. However, existing fault detectors generally use wires to connect to the electric vehicle's interface. When not in use, the wires may become loose and damaged, and they are also inconvenient to store. Furthermore, during use, the internal components of the detector generate heat due to power, and the heat buildup may damage the detector.

[0004] Therefore, it is necessary to invent a rapid fault detection device for electric four-wheeled vehicles to solve the above problems. Utility Model Content

[0023] This utility model provides, for example Figure 1-6 The electric four-wheeled vehicle rapid fault detection instrument shown includes a device housing 1. A voltage display meter 2 is fixedly installed at one end of the device housing 1. The voltage display meter 2 is equipped with a wire for connecting to the electric vehicle. The wire passes through the movable cover 4 and extends to the outside of the winding drum 11. The wire has multiple strands. One end of the multiple strands of wire is respectively equipped with a four-wire plug, a nine-hole plug and a clamp. The four-wire plug is adapted to the connector of the vehicle controller encoder and the motor encoder. The nine-hole plug is adapted to the vehicle operating system plug and the vehicle controller plug. The clamp can be clamped on the electrode of the power supply. The multiple strands of wire can connect the device to multiple positions of the electric vehicle.

[0024] The equipment housing 1 has an internal cavity, and a fixed frame 3 is fixedly installed inside the cavity. A movable cover 4 is slidably installed inside the fixed frame 3. Limiting frames 5 are fixed at both ends of the movable cover 4. A through slot 6 is opened through one end of each side of the movable cover 4. A fixed plate 7 is fixed at the opening of each slot 6. The two fixed plates 7 are both inclined and symmetrically arranged. A ventilation fan 8 is fixed in the middle of each of the two fixed plates 7. The two ventilation fans 8 rotate in opposite directions. The ventilation fan 8 is equipped with a matching controller and power supply. It can be started when the movable cover 4 is pulled outward to achieve heat dissipation inside the equipment housing 1.

[0025] A partition 9 is fixed between the two fixed plates 7, and the partition 9 is fixed inside the movable cover 4. The partition 9 is used to ensure that the air guided by the ventilation fan 8 can be evenly diffused inside the equipment shell 1. A ventilation slot 10 is provided through one end of the outer wall of the equipment shell 1. The ventilation slot 10 is used to cooperate with the ventilation fan 8 to guide air into and out of the equipment shell 1.

[0026] One end of the movable cover 4 is fixedly provided with a winding drum 11. The position of the winding drum 11 corresponds to the ventilation slot 10. Multiple winding guide plates 12 are arranged around the outer side wall of the winding drum 11. Multiple wire grooves 13 are arranged horizontally on the outer side of the winding guide plates 12. The wire grooves 13 are used to guide the winding of the wire.

[0027] One end of the winding drum 11 is fixedly provided with an end plate 14, and the end plate 14 is adapted to the cavity inside the equipment housing 1. The end plate 14 can seal the cavity inside the equipment housing 1, thereby sealing the wire inside the equipment housing 1.

[0028] The end plate 14 has a through slot 15, and the slot 15 has a slidable insert block 16. The inner side wall of the equipment housing 1 has a limiting groove 17 that matches the insert block 16. The middle of the insert block 16 has a square groove 18, and the square groove 18 has a slidable fixing block 19. The fixing block 19 is fixed inside the slot 15, and a spring is provided between the fixing block 19 and the inner wall of the square groove 18. The spring is used to provide the force for the insert block 16 to insert into the limiting groove 17. One end of the insert block 16 is designed with an inclined structure, which facilitates the insertion of the insert block 16 into the limiting groove 17. The other end of the insert block 16 is fixed with a pull ring 20, which is located inside the winding drum 11. The pull ring 20 is used to pull the insert block 16 to release the limiting of the end plate 14.

[0029] Working principle of this utility model:

[0030] When using this device, pulling the pull ring 20 causes the insert block 16 to slide. The insert block 16 slides within the slot 15 until one end of the insert block 16 separates from the limiting groove 17. At this point, the limiting between the end plate 14 and the equipment housing 1 is released. The end plate 14 can then be pulled, causing it to slide the movable cover 4 outwards until the limiting frame 5 at one end of the movable cover 4 is in contact with the fixed frame 3. At this point, the winding drum 11 is fully pulled out, and the position of the ventilation fan 8 corresponds to the ventilation slot 10. The wire wound on the outside of the winding drum 11 can then be removed, and the wire can be... It connects to the vehicle control encoder, motor encoder, and battery of the electric vehicle, and then detects the fault of the electric vehicle by observing the reading on the voltage display meter 2. During the detection process, the voltage display meter 2 and the equipment inside the equipment housing 1 generate heat due to the power load. At this time, one set of ventilation fans 8 can draw outside air into the equipment housing 1, and another set of ventilation fans 8 can draw out the air inside the equipment housing 1. In this state, the air circulates inside and outside the equipment housing 1. During the air circulation, the heat is carried out to avoid heat accumulation and damage to the device.

[0031] It should be noted that the wires are multi-stranded, with a four-wire plug, a nine-hole plug, and a clamp at one end. The four-wire plug is compatible with the connectors of the vehicle controller encoder and the motor encoder, the nine-hole plug is compatible with the vehicle operating system plug and the vehicle controller plug, and the clamp can be clamped onto the power supply electrode. The multi-stranded wires can connect the device to multiple locations on the electric vehicle.

[0032] When troubleshooting a vehicle, you can determine if the vehicle key is faulty by turning on the vehicle key switch and observing whether the voltage display meter 2 changes. If the display is normal, the vehicle key is not faulty. If the voltage display meter 2 does not change, there is a fault in the battery connection wire, key switch circuit, or key switch controller circuit. You can determine if the vehicle controller encoder is faulty by manually turning the drive wheel and observing whether the voltage display meter 2 changes. If the display is normal, there is no fault. If the voltage display meter 2 does not change, the vehicle control encoder is damaged. You can determine if the motor encoder is faulty by lightly pressing the accelerator pedal and observing whether the voltage display meter 2 changes. If the display is normal, there is no fault. If the voltage display meter 2 does not change, the motor encoder is faulty.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
