Description

Technical Field

[0001] The present invention relates to the technical field of charging vehicles, and in particular to a trailer-type mobile charging vehicle. Background Art

[0002] With the rise of electric vehicles, the electrification of large vehicles has also attracted more and more attention. However, these large vehicles have high power and high energy consumption. If they are fully powered by batteries, they must have a large capacity. If the battery capacity is not large enough, they need to stop and charge frequently. They may need to stop and charge after running only one or two hundred kilometers, which seriously affects the operation of the vehicle.

[0003] Therefore, some manufacturers have manufactured charging vehicles, which are equipped with batteries and can be used after being fully charged at designated charging stations. After scanning the code to turn on the charging vehicle, the charging vehicle can be hung behind the vehicle, and the charging vehicle charges the vehicle when the vehicle pulls the charging vehicle together. However, existing charging vehicles have some defects, such as:

[0004] After charging the electric vehicle, it is not convenient for the charging vehicle to store the charging cable, and the charging cable is exposed and easily damaged. The vehicle pull rod is not convenient to store after being removed from the electric vehicle, which will cause the charging vehicle to occupy a large area when charging itself. In addition, it is not convenient to pull out the charging cable when charging itself, and the charging vehicle has only two wheels, which is easy to tip over when charging after being removed from the electric vehicle. In summary, the existing charging vehicles have the technical defect of being inconvenient to use. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a trailer-type mobile charging vehicle to solve the problem that the existing charging vehicles are inconvenient to use.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

A storage battery is fixed in the second inner cavity. The charging end and the power transmission end of the storage battery are respectively connected to an internal charging cable and an external charging cable. The internal charging cable passes through the rear side of the vehicle body after passing through the third inner cavity. The external charging cable passes through the front side of the vehicle body after passing through the first inner cavity. A pull rod hiding groove is provided on the front side of the vehicle body.

[0012] Both ends of the lower side of the first inner cavity and both ends of the lower side of the third inner cavity move up and down through the ground-affecting columns, and the rotating rod and the second rotating frame press down the ground-affecting columns when they rotate to a horizontal state;

[0013] First rotating frame: the lower end of the first rotating frame is fixed to the rear end of the vehicle drawbar, the first rotating frame is located in the second inner cavity, the first rotating frame and the vehicle drawbar are perpendicular to each other, a fixing assembly is installed between the first rotating frame and the vehicle body, and the first rotating frame is fixed in the vehicle body through the fixing assembly when it is rotated to a vertical state;

[0014] Through the above technical solution, the internal charging cable and the external charging cable of the battery are connected to the rear and front sides of the vehicle body respectively. Without turning the vehicle body, the internal charging cable can be connected to the external charging station and the external charging cable can be connected to the electric vehicle, which is more convenient to use.

[0015] When the car pull rod is pulled to a horizontal state, the car pull rod can be fixed behind the electric car. At the same time, the car pull rod rotates the rotating rod, the first rotating frame and the second rotating frame to a vertical state. The rotating rod can push out the external charging cable to facilitate connecting it to the charging port of the electric car. The first rotating frame can be fixed in the vehicle body by a fixing component, so that the car pull rod can be kept horizontal and stably connected to the electric car. The second rotating frame can pull the internal charging cable back into the third inner cavity to avoid exposing the internal charging cable to the outside, that is, automatically realize the extension of the external charging cable, the fixing of the first rotating frame and the car pull rod, and the retraction of the internal charging cable;

[0016] When the electric vehicle needs to be returned after charging, the vehicle pull rod can be rotated to a vertical state, and the vehicle pull rod is inserted into the pull rod hiding groove to reduce the floor space. At the same time, the vehicle pull rod rotates the rotating rod, the first rotating frame and the second rotating frame to a horizontal state. The rotating rod can pull the external charging cable back into the first inner cavity to avoid the internal charging cable being exposed to the outside. The second rotating frame can release the internal charging cable, making it easy to pull out the internal charging cable and insert it into the charging station.

[0017] When the rotating rod and the second rotating frame are rotated to a horizontal state, the rotating rod and the second rotating frame can be pressed downward against the ground column, so that the ground column is pressed against the ground to support the device and prevent it from falling over;

[0018] In summary, the device can control the retraction and extension of the internal charging cable, the retraction and extension of the external charging cable, and the support of the device by the ground support column only by controlling the rotation of the vehicle pull rod, and is easy to use.

[0019] Preferably, the fixing assembly includes an electric push rod and a card frame, the electric push rod is fixed in the side of the second inner cavity, the output end of the electric push rod is fixed with a card frame facing upward, and the lower end of the card frame is movably inserted into the upper end of the first rotating frame;

[0020] Through the above technical solution, when the electric push rod pulls the clamping frame downward, the clamping frame can be inserted into the upper end of the first rotating frame, so that the first rotating frame no longer rotates, and the first rotating frame and the vehicle pull rod are fixed.

[0021] Preferably, the upper end of the clamping frame is integrally formed with an end head, and the front end of the vehicle tie rod is provided with a clamping hole, and when the vehicle tie rod is rotated to a vertical state, the end head is upwardly inserted into the clamping hole;

[0022] Through the above technical solution, when the card frame is pushed on the electric push rod, the card frame drives the end head to move up, and the end head is inserted upward into the card hole to fix the car draw rod, thereby preventing the car draw rod from rotating at will without human operation.

[0023] Preferably, a telescopic rod is movably passed through the upper end of the rotating rod, a second spring is fixed between the lower end of the telescopic rod and the inner bottom side of the rotating rod, a wire clamping frame is fixed to the upper end of the telescopic rod, the external charging cable is indirectly fixed to the upper end of the rotating rod by passing through the wire clamping frame, an arc plate is fixed in the first inner cavity, and the upper end of the wire clamping frame abuts against the inner side of the arc plate;

[0024] Through the above technical solution, the second spring pushes the telescopic rod upward, so that the upper end height of the telescopic rod becomes higher, so that the wire clamping frame can send the external charging cable out of the first inner cavity as much as possible. When the rotating rod rotates to horizontal, the arc plate pushes the telescopic rod back into the rotating rod, and the second spring is compressed, so that the rotating rod, the telescopic rod and the wire clamping frame adapt to the width of the vehicle body.

[0025] Preferably, a first push plate is movably inserted in the wire clamping frame, a third spring is fixed between the first push plate and the inner side of the wire clamping frame, the external charging cable movably passes through the wire clamping frame and the third spring, and the external charging cable is fixedly passed through the first push plate;

[0026] Through the above technical solution, when the rotating rod is not fully rotated to the horizontal state, the external charging cable is completely pulled back to prevent the external charging cable from blocking the vehicle pull rod from rotating into the pull rod hiding groove. When the rotating rod is fully rotated to the horizontal state, the third spring is stretched, so that the wire clamping frame moves downward and the first push plate does not move downward.

[0027] Preferably, turn signals, brake lights and fog lights are fixed at both ends of the rear side of the vehicle body;

[0028] Through the above technical solution, the turn signal lights, brake lights and fog lights can display the driving status to the vehicles behind.

[0029] Preferably, a first spring is fixed between the upper end of the ground-affecting column and the vehicle body;

[0030] Through the above technical solution, when the ground-affecting column is not pressed by the rotating rod and the second rotating frame, the first spring pushes the ground-affecting column upward to prevent the ground-affecting column from contacting the ground when the device moves.

[0032] Through the above technical solution, when the internal charging cable is not needed, the end of the internal charging cable can be hidden in the second charging head retention port for protection. When the internal charging cable needs to be pulled out, the fourth spring pushes the second push plate, and the second push plate can push out the end of the internal charging cable, making it convenient to pull the internal charging cable.

[0033] Preferably, the front side of the first inner cavity and the front side of the third inner cavity are both provided with air inlet holes, the rear side of the first inner cavity and the rear side of the third inner cavity are both provided with air outlet holes, and filter screens are fixed in the air inlet holes and the air outlet holes, and a heat conducting plate is fixed between a side of the second inner cavity close to the first inner cavity and a side of the second inner cavity close to the third inner cavity, and the heat conducting plate contacts the battery;

[0034] Through the above technical solution, the heat of the battery is transferred to the heat conducting plate, and the heat conducting plate transfers the heat to the first inner cavity and the third inner cavity through the side wall of the second inner cavity close to the first inner cavity and the side wall of the second inner cavity close to the third inner cavity, and the air takes away the heat through the air inlet and the air outlet, that is, the battery is cooled to avoid excessive heating of the battery.

[0035] The beneficial effects of the present invention are:

[0036] 1. Connect the internal charging cable and external charging cable of the battery to the rear and front sides of the vehicle body respectively. Without turning the vehicle body, the internal charging cable can be connected to the external charging station backwards, and the external charging cable can be connected to the electric vehicle forwards. The charging vehicle does not need to turn, which is more convenient to use.

[0037] 2. When the car pull rod is pulled to a horizontal state, the car pull rod can be fixed behind the electric car. At the same time, the car pull rod rotates the rotating rod, the first rotating frame and the second rotating frame to a vertical state. The rotating rod can push out the external charging cable to facilitate connecting it to the charging port of the electric car. The first rotating frame can be fixed to the vehicle body through a fixing component, so that the car pull rod can be kept horizontal and stably connected to the electric car. The second rotating frame can pull the internal charging cable back to the third inner cavity to avoid exposing the internal charging cable to the outside, that is, automatically realize the extension of the external charging cable, the fixing of the first rotating frame and the car pull rod, and the retraction of the internal charging cable;

[0038] 3. When the electric vehicle needs to be returned after charging, the vehicle pull rod can be rotated to a vertical state, and the vehicle pull rod is inserted into the pull rod hiding groove to reduce the floor space. At the same time, the vehicle pull rod rotates the rotating rod, the first rotating frame and the second rotating frame to a horizontal state. The rotating rod can pull the external charging cable back into the first inner cavity to avoid the internal charging cable being exposed to the outside. The second rotating frame can release the internal charging cable, making it easy to pull out the internal charging cable and insert it into the charging station.

[0039] 4. When the rotating rod and the second rotating frame are rotated to a horizontal state, the rotating rod and the second rotating frame can be pressed downward against the ground column, so that the ground column is against the ground to support the device and prevent it from tipping over.

[0067] Working principle of this device:

[0068] When the device is parked in the charging station, the vehicle pull rod 4 is hidden in the pull rod hiding groove 3, and the end 27 is inserted into the clamping hole 5 upward to fix the vehicle pull rod 4. At this time, the rotating rod 15, the first rotating frame 24 and the second rotating frame 33 are in a horizontal state, and the rotating rod 15, the clamping wire frame 21 and the second rotating frame 33 are pressed downward against the ground column 14, the first spring 13 is compressed, and the four ground columns 14 are pressed against the ground to support the device to prevent the device from tipping over. At this time, the internal charging cable 36 can be pulled out and connected to the charging station to charge the battery 30;

[0069] Before use, the output end of the mobile phone terminal 40 sends a signal to the data cloud 41, and the data cloud 41 sends a signal to the in-vehicle control center 42, so that the in-vehicle control center 42 powers on the turn signal 8, the brake light 9 and the fog light 10. At the same time, the in-vehicle control center 42 powers on the electric push rod 25, and the electric push rod 25 drives the card frame 26 to move downward, so that the end 27 moves downward away from the card hole 5, so that the car pull rod 4 can rotate freely, pull the car pull rod 4 out of the pull rod hiding groove 3, and rotate the car pull rod 4 to a horizontal state. The first spring 13 pushes the ground column 14 upward, and the ground column 14 leaves the ground upward. The device can move freely, fix the car pull rod 4 to the rear of the electric car, and the car pull rod 4 drives the first rotating frame 24 to rotate from a horizontal state to a vertical state. The push rod 25 drives the card frame 26 to move downward, and the card frame 26 is inserted downward into the first rotating frame 24 to fix the first rotating frame 24, that is, to fix the vehicle pull rod 4. The vehicle pull rod 4 drives the rotating rod 15 to rotate from a horizontal state to a vertical state. At the same time, the second spring 16 pushes the telescopic rod 17 upward. At this time, the external charging cable 7 can be pulled, and the external charging cable 7 can be pulled out and inserted into the charging port of the electric vehicle. The vehicle pull rod 4 drives the second rotating frame 33 to rotate from a horizontal state to a vertical state, so that the first winding post 32 and the second winding post 35 are separated from each other, and the distance between the first winding post 32 and the second winding post 35 becomes larger, and the length of the internal charging cable 36 between the two becomes longer, so that the internal charging cable 36 can be directly pulled back into the third inner cavity 31, and there is no need to manually retract the internal charging cable 36.
