Technical Field
[0001] This utility model relates to the field of tricycle technology, specifically to an external discharge device for tricycles. Background Technology
[0002] With the widespread adoption of electric tricycles in urban and rural logistics, short-distance transportation, and agricultural production and daily life, their functions are no longer limited to basic passenger and cargo transport; users' demands for additional functions are becoming increasingly prominent. In practical applications, electric tricycles often need to operate outdoors for extended periods, such as powering irrigation equipment in rural areas, providing electricity for small vendors in temporary markets, powering tools for outdoor maintenance work, and providing lighting and communication equipment in emergency situations. However, currently available electric tricycles are generally only equipped with battery packs for driving the vehicle, while gasoline tricycles, although equipped with battery packs for lighting and starting, lack dedicated external discharge interfaces and supporting power supply systems. This means that the electrical energy stored in the battery packs cannot directly provide power to external electrical equipment, greatly limiting the expansion of electric tricycle usage scenarios. Utility Model Content
[0003] In view of the problems existing in the prior art, this utility model discloses a three-wheeled vehicle external discharge device. The technical solution adopted is as follows: it includes a vehicle body, and a battery pack is fixedly installed at the bottom of the vehicle body by a fixing steel strip. The output end of the battery pack is connected to one end of a cable, and the other end of the cable is connected to the input end of an inverter. The inverter is fixedly installed at the bottom of the vehicle body, and the output end of the inverter is connected to one end of a second cable. The other end of the second cable is connected to the input end of a three-hole socket. The three-hole socket is fixedly installed in a groove on the side of the vehicle body, and a heat dissipation mechanism is installed on the three-hole socket. A cover plate is rotatably installed on the side of the vehicle body, and the cover plate cooperates with the groove on the side of the vehicle body. A reset switch that cooperates with the cover plate is fixedly installed in the groove on the side of the vehicle body, and the reset switch is electrically connected to the battery pack. The heat dissipation mechanism includes a heat-conducting ring, a cooling fan, heat sinks, heat pipes, a fixing rod, and an air outlet. The inner side of the heat-conducting ring is fixedly connected to the side of a three-hole socket. Two heat pipes are fixedly installed on the side of the heat-conducting ring, and several heat sinks are fixedly installed on each of the two heat pipes. There are two cooling fans, and the four corners of the two cooling fans are fixedly connected to the inner side of the vehicle body by fixing rods. The two cooling fans are located on one side of two sets of heat sinks. An air outlet is provided on the inner wall of the vehicle body to cooperate with the two cooling fans. The air outlet is elongated and distributed in an array along the direction of the heat sinks. The two cooling fans are electrically connected to a reset switch.
[0004] As a preferred embodiment of this utility model, the main material of the three-hole socket is thermally conductive plastic.
[0005] As a preferred embodiment of this utility model, a rubber ring is fixedly installed at the edge of the side of the cover plate, and the rubber ring cooperates with the annular stepped surface in the groove on the side of the vehicle body.
[0006] As a preferred embodiment of this utility model, a rubber pad is fixedly installed in the middle of the side of the cover plate, and the rubber pad cooperates with the three-hole socket.
[0007] As a preferred embodiment of this utility model, two dust filters are fixedly installed in the groove on the side of the vehicle body, and the two dust filters are respectively located on the outside of the two sets of air outlets.
[0008] The beneficial effects of this utility model are as follows: 1. This utility model, through the coordinated operation of a battery pack, inverter, and three-hole socket, enables the external output of electrical energy from the battery pack of an electric tricycle. The inverter converts the low-voltage DC power of the battery pack into 220V AC power, which is compatible with external devices. Combined with a standard three-hole socket, it can directly power various AC electrical devices such as irrigation pumps, small household appliances, repair tools, and emergency lighting. This completely breaks the functional limitations of electric tricycles, which are only used for driving, and gasoline tricycles, which do not utilize battery packs for external power supply. It transforms these tricycles into mobile outdoor power stations, particularly suitable for rural areas, outdoor operations, and emergency rescue scenarios, greatly enhancing the overall practicality and market competitiveness of electric tricycles.
[0009] 2. The heat dissipation mechanism enables efficient heat dissipation during external discharge. The heat generated by the three-hole socket during operation is quickly conducted to the heat pipe through the heat conduction ring. The heat pipe then distributes the heat to multiple heat sinks, increasing the heat dissipation area. At the same time, the cooling fan, which is linked to the reset switch, starts synchronously. It accelerates airflow through the air outlet and quickly exhausts the heat from the heat sink to the outside of the vehicle body. This effectively reduces the operating temperature of the three-hole socket, preventing component performance degradation or burnout due to high temperature, and ensuring the stability of power supply under long-term, high-load conditions.
[0010] 3. The three-hole socket body is made of thermally conductive plastic, which not only has good insulation properties but also improves heat conduction efficiency. Combined with the heat dissipation mechanism, it further optimizes heat dissipation. The rubber ring fits tightly against the annular stepped surface within the groove, effectively preventing rainwater and dust from entering the groove through the gap between the cover and the vehicle body. The rubber pad, when the cover is closed, makes close contact with the three-hole socket, further sealing the socket holes and preventing dust from entering, enhancing protective details. The dust filter prevents external dust from entering the vehicle interior through the air vents. Attached Figure Description

Detailed Implementation
[0013] Example 1 like Figures 1 to 5As shown, this utility model discloses a three-wheeled vehicle external discharge device. The technical solution includes a vehicle body 1. A battery pack 2 is fixedly installed at the bottom of the vehicle body 1 via a fixing steel band 3. The output end of the battery pack 2 is connected to one end of a cable 4, and the other end of the cable 4 is connected to the input end of an inverter 5. The inverter 5 is fixedly installed at the bottom of the vehicle body 1. The output end of the inverter 5 is connected to one end of a second cable 6, and the other end of the second cable 6 is connected to the input end of a three-hole socket 7. The three-hole socket 7 is fixedly installed in a groove on the side of the vehicle body 1. A heat dissipation mechanism 8 is installed on the three-hole socket 7. The main body of the three-hole socket 7 is made of thermally conductive plastic, which has good insulation performance and can improve heat conduction efficiency. Combined with the heat dissipation mechanism, the heat dissipation effect is further optimized. The rotating mounting on the side of the vehicle body 1... The vehicle is equipped with a cover plate 9, which fits into a groove on the side of the vehicle body 1. A rubber ring 11 is fixedly installed at the edge of the side of the cover plate 9, and the rubber ring 11 fits into the annular stepped surface in the groove on the side of the vehicle body 1. The tight fit between the rubber ring 11 and the annular stepped surface in the groove can effectively prevent rainwater and dust from entering the groove from the gap between the cover plate 9 and the vehicle body. A rubber pad 10 is fixedly installed in the middle of the side of the cover plate 9, and the rubber pad 10 fits into the three-hole socket 7. When the cover plate is closed, the rubber pad 10 can make tight contact with the three-hole socket, which can further seal the socket hole. A reset switch 13, which fits into the cover plate 9, is fixedly installed in the groove on the side of the vehicle body 1. The reset switch 13 is electrically connected to the battery pack 2. Through the coordinated operation of the battery pack 2, the inverter 5, and the three-hole socket 7, the electric tricycle's battery pack can output electrical energy to the outside. The inverter 5 converts the low-voltage DC power of the battery pack 2 into 220V AC power for external devices. With the standard three-hole socket 7, it can directly power various AC electrical devices such as irrigation pumps, small household appliances, repair tools, and emergency lighting. This completely breaks the limitation of electric tricycles being used only for driving and gasoline tricycles not utilizing battery packs for external power supply. It makes them mobile outdoor power stations, especially suitable for rural areas, outdoor operations, emergency rescue and other scenarios, greatly improving the overall practicality and market competitiveness of electric tricycles. The heat dissipation mechanism 8 includes a heat-conducting ring 81, a cooling fan 82, heat sinks 83, heat pipes 84, a fixing rod 85, and an air outlet 86. The inner side of the heat-conducting ring 81 is fixedly connected to the side of the three-hole socket 7. Two heat pipes 84 are fixedly installed on the side of the heat-conducting ring 81, and several heat sinks 83 are fixedly installed on each of the two heat pipes 84. There are two cooling fans 82, and the four corners of the two cooling fans 82 are fixedly connected to the inner side of the vehicle body 1 by fixing rods 85. The two cooling fans 82 are located on one side of the two sets of heat sinks 83. An air outlet 86 is opened on the inner wall of the vehicle body 1 to cooperate with the two cooling fans 82. The air outlet 86 is elongated and arranged in an array along the direction of the heat sinks 83. Two dust filters 12 are fixedly installed in the groove on the side of the vehicle body 1. Two dust filters 12 are located on the outside of the two sets of air vents 86. The dust filters 12 can prevent external dust from entering the vehicle body through the air vents 86. Two cooling fans 82 are electrically connected to the reset switch 13. The cooling mechanism 8 can achieve efficient heat dissipation during external discharge. The heat generated by the three-hole socket 7 when it is working is quickly conducted to the heat pipe 84 through the heat conduction ring 81. The heat pipe 84 distributes the heat to multiple heat sinks 83, increasing the heat dissipation area. At the same time, the cooling fans 82 linked with the reset switch 13 start synchronously. They accelerate the air flow through the air vents 86 and quickly expel the heat on the heat sinks to the outside of the vehicle body. This can effectively reduce the working temperature of the three-hole socket 7, avoid component performance degradation or burnout due to high temperature, and ensure the stability of power supply for long periods of time and high load.
[0014] The working principle of this utility model is as follows: During external discharge, the cover plate 9 can be opened, and the plug of the electrical equipment can be inserted into the three-hole socket 7. At this time, the low-voltage DC power output by the battery pack 2 is transmitted to the inverter 5 via the cable 4, and the inverter 5 converts it to 220V. After AC power is supplied, it is then transmitted via the second cable 6 to the three-hole socket 7 in the groove on the side of the vehicle body 1 for use by external AC electrical equipment. At the same time, the heat generated by the three-hole socket 7 during operation is transferred through its thermally conductive plastic body to the thermally conductive ring 81 fixed on the side. The thermally conductive ring 81 then conducts the heat to two heat pipes 84. The heat pipes 84 distribute the heat to several heat sinks 83 on the surface. When the cover 9 is opened, the reset switch 13 is released, which powers on the battery pack 2 and the two cooling fans 82. The airflow generated by the cooling fans 82 exhausts the heat on the heat sinks 83 through the long strip-shaped array of air vents 86 on the inner wall of the vehicle body 1. The dust filter 12 on the outside of the air vents 86 can prevent external dust from entering the interior of the vehicle body 1. In addition, the rubber ring 11 on the edge of the cover 9 can fit and seal with the annular step surface of the groove, and the rubber pad 10 in the middle of the cover 9 can contact the three-hole socket 7 to seal the socket hole, thus achieving dust and water protection and ensuring the safe and stable operation of the device.
