Description

Technical Field

[0001] The invention relates to an electric vehicle charging pile, and in particular to a charging pile with a protective structure. Background Art

[0002] Nowadays, electric vehicles are becoming more and more popular. The convenience and safety of charging piles are undoubtedly an important part of the electric vehicle experience. At present, electric vehicle users have some inconveniences and insecurities during the charging process. Since the charging piles are set up with parking spaces, there are some random parking and occupation phenomena, which make it impossible for the cars that need to be charged to charge normally. In addition, since different models of vehicles are of different sizes and the charging sockets are set in different positions, in order to facilitate the charging of various vehicles, the existing charging cables are usually designed to be long enough to reach a larger range. However, if the charging cable is too long, the wire will touch the ground during long use, and then cause wear during the dragging process, exposing the internal wires. Once the positive and negative poles are short-circuited, a large amount of heat will be generated instantly, causing a fire. In addition, after charging is completed, if the charging gun is not placed properly, it is very easy to cause bumps and falls, which will cause cracks and damage to the charging gun head. The internal metal contacts, circuits and other structures may be deformed due to bumps. If the metal contacts are deformed, it will change its contact state with the vehicle charging interface, affecting the charging effect or making it impossible to use it normally. Summary of the invention

The protective charging cart includes a car body, a driving device, a winding wheel and a protective adjustment mechanism, the winding wheel is rotatably arranged in the car body, the charging line bypasses the winding wheel, a winding motor is arranged in the car body, the winding wheel is connected to the winding motor, and the The other end of the charging cable is connected to a charging gun, and a charging port is provided on the vehicle shell near the charging gun; the protective adjustment mechanism includes a first adjustment component and a second adjustment component, and the first adjustment component and the second adjustment component are respectively arranged on both sides of the winding wheel. The first adjustment component is used to protect the charging cable to prevent it from touching the ground and being dragged and worn, and the second adjustment component is used to protect the charging gun to prevent it from falling off or bumping; the driving device includes wheels, a power mechanism, a steering mechanism, a braking mechanism, etc. for driving its moving device, the first adjustment component is close to the side of the cable inlet, and the second adjustment component is close to the side of the charging gun.

[0005] Further, the first adjusting component includes a first adjusting wheel, a second adjusting wheel, a first adjusting slider, a second adjusting slider, a first slide rail, a first driving rod, a first pushing rod and a second pushing rod. The first slide rail is fixedly arranged in the vehicle shell and close to the side of the wire inlet. The first adjusting slider and the second adjusting slider are respectively slidably connected to the upper and lower ends of the first slide rail. The first adjusting wheel and the second adjusting wheel are respectively rotationally arranged on the first adjusting slider and the second adjusting slider. The charging cable bypasses the second adjusting wheel and the first adjusting wheel in turn. The first driving rod is rotationally arranged in the vehicle shell. The first pushing rod and the second pushing rod are respectively rotationally connected to the two ends of the first driving rod. The first pushing rod and the first adjusting slider are rotationally connected. The second pushing rod and the second adjusting slider are rotationally connected. A first motor is arranged in the vehicle shell, and the first driving rod is connected to the first motor.

[0006] By controlling the first driving rod to rotate, the first pushing rod and the second pushing rod push and pull the first adjusting slider and the second adjusting slider. When the first adjusting slider and the second adjusting slider move relative to each other, the charging cable is loosened; and when the first adjusting slider and the second adjusting slider are controlled to move in opposite directions, the charging cable is tightened.

[0007] When the protective charging vehicle is moving, the charging cable on the side of the cable inlet needs to be gradually released; when charging is needed, the charging cable on one side of the charging gun is released, and because the reel rotates, it will simultaneously release and retract the charging cables at both ends. Therefore, by setting a first adjustment component, the tightness of the charging cable can be adjusted, and then when the charging cable on the side of the cable inlet needs to be released and the charging cable on the side of the charging gun is not released, the charging cable can be loosened by adjusting the first adjustment component to provide a margin for the charging cable to be released; when the charging cable on one side of the charging gun needs to be released and the charging cable on the side of the cable inlet is not released, after the reel releases the charging cables at both ends, the charging cable at one end of the cable inlet is loosened or tightened by adjusting the first adjustment component; and then through the cooperation of the first adjustment component and the reel, the effect of controlling the one-way reeling without affecting the reeling on the other side is achieved.

[0008] Furthermore, the first adjustment wheel and the second adjustment wheel are provided with tension sensors, which are connected to the first motor through the control circuit. The tension sensors detect the tension changes of the charging cable in real time. When the cable is dragged on the ground, the tension of the cable will change, usually becoming smaller. The tension sensor can accurately measure the tension value of the cable and convert it into an electrical signal output.

[0009] Further, the second adjusting component includes a third adjusting wheel, a fourth adjusting wheel, a third adjusting slider, a fourth adjusting slider, a second slide rail, a second driving rod, a third pushing rod and a fourth pushing rod.

A second motor is arranged in the vehicle shell, and the second driving rod is connected to the second motor.

[0010] By controlling the second driving rod to rotate, the third adjusting slider and the fourth adjusting slider are pushed and pulled by the third pushing rod and the fourth pushing rod. When the third adjusting slider and the fourth adjusting slider move relative to each other, the charging cable is loosened; and when the third adjusting slider and the fourth adjusting slider are controlled to move in the opposite direction, the charging cable is tightened.

[0011] Furthermore, the charging gun is provided with a gravity sensor or an acceleration sensor. When the charging gun is charged or placed normally, the sensor is in a stable state. Once the charging gun falls, its gravity or acceleration will change significantly. The sensor can quickly capture these change signals and convert them into electrical signal outputs to detect whether the charging gun has fallen.

[0012] A control circuit is arranged in the protective charging cart, and the control circuit is responsible for receiving the electrical signal from the sensor, and processing and analyzing the electrical signal. The control circuit is connected to the winding motor control, and the control circuit is connected to the first motor and the second motor control. When it is determined that the charging gun has fallen, the control circuit will issue a corresponding control instruction to control the winding wheel to rewind quickly, and the second driving rod to tighten quickly, so as to retract the charging gun to prevent it from falling to the ground and causing bumps.

[0013] Furthermore, in order to prevent the charging cable from being over-reeled and causing damage to the charging gun, a socket for placing the charging gun is provided in the vehicle shell, and an anti-collision buffer pad is provided on the charging gun to prevent collision with the socket.

[0014] In one embodiment, tension sensors are provided in the winding wheel, the third adjusting wheel and the fourth adjusting wheel.

After the tension sensor detects this change, it converts the tension signal into an electrical signal, controls the winding wheel to stop winding, and stops the second adjusting component from being tensioned.

[0015] In one embodiment, a photoelectric sensor is installed in the vehicle shell near the charging port, and a reflective mark is set at a certain interval on the charging cable. When the charging cable is received into the vehicle shell, the photoelectric sensor detects the passage of the mark. When a specific number of marks are detected passing, it means that the charging cable has been wound up to a set length. The photoelectric sensor transmits a signal to the control circuit, and the control circuit controls the winding motor and the second motor to stop rotating.

[0016] Furthermore, a first guide wheel is provided in the vehicle shell near the cable inlet, and the charging cable is connected to the first guide wheel and then to the second adjusting wheel; a second guide wheel is provided in the vehicle shell between the winding wheel and the second adjusting component, and the charging cable is connected to the second guide wheel and then to the third adjusting wheel; a third guide wheel is provided in the vehicle shell, and the charging cable is connected to the fourth adjusting wheel and then to the third guide wheel.

At the same time, the route can be updated in real time during driving to avoid obstacles and other vehicles and pedestrians; the protective charging cart is provided with a vehicle-mounted controller to control the drive of the protective charging cart, and by setting a communication module, the protective charging cart and the charging pile can communicate to obtain the car's charging needs.

[0018] In one embodiment, a fixed track is set on the ground, and the protective charging vehicle travels a fixed route on the fixed track. The fixed track is set on both sides of the parking space. After the charging vehicle is parked according to the parking space, the protective charging vehicle travels along the fixed track to the vicinity of the vehicle.

[0019] The beneficial effects of the present invention are as follows: by arranging a movable protective charging cart on the charging pile, the charging gun can be carried to the vicinity of the vehicle that needs to be charged, thereby providing convenience for charging the vehicle; a winding wheel is arranged to wind up the charging cable, and by retracting and releasing the charging cable, the coverage of the charging cable is improved, and in view of the trouble caused by the two-way retraction and release of the winding wheel in the prior art, the two sides of the winding wheel are adjusted by the first adjustment component and the second adjustment component. When one side needs to be retracted, the other side is adjusted by tightening and loosening the charging cable, thereby achieving the effect of unidirectional retraction and release of the charging cable; and by arranging the first adjustment component, the released charging cable can be always adjusted to be in a tensioned state, thereby avoiding the problem that the charging cable touches the ground and generates friction with the ground, thereby causing damage to the charging cable. By arranging the second adjustment component, when the charging gun head falls, the winding wheel can be cooperated to tighten it in time, and the charging cable can be retracted into the car, thereby avoiding the charging gun from falling and bumping, thereby achieving protection for the charging gun.

A first motor 24 is arranged in the car body 6, and the first motor 24 is connected to the first driving rod 21.

[0034] By controlling the first driving rod 21 to rotate, the first adjusting slider 18 and the second adjusting slider 19 are pushed and pulled by the first pushing rod 22 and the second pushing rod 23. When the first adjusting slider 18 and the second adjusting slider 19 move relative to each other, the charging cable 4 is loosened; and when the first adjusting slider 18 and the second adjusting slider 19 are controlled to move in opposite directions, the charging cable 4 is tightened.

[0035] When the protective charging cart 2 is moving, the charging cable 4 on the side of the cable inlet 5 needs to be gradually released; when charging is needed, the charging cable 4 on one side of the charging gun is released, and because the reel 8 rotates, the charging cables 4 at both ends will be released and reeled in at the same time. Therefore, by setting the first adjusting component 14, the tightness of the charging cable 4 can be adjusted, and then when the charging cable 4 on the side of the cable inlet 5 needs to be released and the charging cable 4 on the side of the charging gun is not released, the charging cable 4 can be adjusted to be loosened by the first adjusting component 14 to provide a margin for the charging cable 4 to be released; when the charging cable 4 on one side of the charging gun needs to be released and the charging cable 4 on the side of the cable inlet 5 is not released, after the reel 8 releases the charging cables 4 at both ends, the charging cable 4 at one end of the cable inlet 5 is adjusted to be loose or tight by the first adjusting component 14; and then through the cooperation of the first adjusting component 14 and the reel 8, the effect of controlling the unidirectional reeling without affecting the reeling on the other side is achieved.

[0036] The first adjustment wheel 16 and the second adjustment wheel 17 are provided with tension sensors, which are connected to the first motor 24 through the control circuit. The tension sensors detect the tension changes of the charging cable 4 in real time. When the cable is dragged on the ground, the tension of the cable will change, usually becoming smaller. The tension sensor can accurately measure the tension value of the cable and convert it into an electrical signal output.

[0037] like Figure 4 The second adjustment component 15 includes a third adjustment wheel 25, a fourth adjustment wheel 26, a third adjustment slider 27, a fourth adjustment slider 28, a second slide rail 29, a second drive rod 30, a third push rod 31 and a fourth push rod 32. The second slide rail 29 is fixedly arranged in the vehicle shell 6. The third adjustment slider 27 and the fourth adjustment slider 28 are respectively slidably connected to the upper and lower ends of the second slide rail 29. The third adjustment wheel 25 and the fourth adjustment wheel 26 are respectively rotatably arranged on the third adjustment slider 27 and the fourth adjustment slider 28. The charging line 4 bypasses the third adjustment wheel 25 and the fourth adjustment wheel 26 in sequence. The second drive rod 30 is rotatably arranged in the vehicle shell 6. The third push rod 31 and the fourth push rod 32 are respectively rotatably connected to the two ends of the second drive rod 30. The third push rod 31 is rotatably connected to the third adjustment slider 27, and the fourth push rod 32 is rotatably connected to the fourth adjustment slider 28. A second motor 11 is arranged in the vehicle shell 6, and the second drive rod 30 is connected to the second motor 11.

[0038] By controlling the second driving rod 30 to rotate, the third adjusting slider 27 and the fourth adjusting slider 28 are pushed and pulled by the third pushing rod 31 and the fourth pushing rod 32. When the third adjusting slider 27 and the fourth adjusting slider 28 move relative to each other, the charging cable 4 is loosened; and when the third adjusting slider 27 and the fourth adjusting slider 28 are controlled to move in the opposite direction, the charging cable 4 is tightened.

[0039] The charging gun is provided with a gravity sensor or an acceleration sensor. When the charging gun is charged or placed normally, the sensor is in a stable state. Once the charging gun falls, its gravity or acceleration will change significantly. The sensor can quickly capture these change signals and convert them into electrical signal outputs to detect whether the charging gun has fallen;

[0040] A control circuit is arranged in the protective charging cart 2, and the control circuit is responsible for receiving the electrical signal from the sensor, and processing and analyzing the electrical signal. The control circuit is controlled and connected to the winding motor 10, and the control circuit is controlled and connected to the first motor 24 and the second motor 11. When it is determined that the charging gun has fallen, the control circuit will issue a corresponding control instruction to control the winding wheel 8 to rewind quickly, and the second driving rod 30 to tighten quickly, so as to retract the charging gun to prevent it from falling to the ground and causing a bump.

[0041] In order to prevent the charging cable 4 from being over-reeled and causing damage to the charging gun, a socket 33 for placing the charging gun is provided in the vehicle shell 6, and an anti-collision buffer pad 34 is provided on the charging gun to prevent collision with the socket 33.

[0042] In one embodiment, tension sensors are provided in the winding wheel 8, the third adjusting wheel 25, and the fourth adjusting wheel 26. The tension sensors and the winding motor 10 and the second motor 11 are connected through a control circuit. When the cable is not able to be wound, the tension increases sharply. After the tension sensor detects this change, it converts the tension signal into an electrical signal, controls the winding wheel 8 to stop winding, and the second adjusting component 15 to stop tensioning.

[0043] In one embodiment, a photoelectric sensor is installed in the vehicle shell 6 near the charging port 13, and a reflective mark is set on the charging cable 4 at a certain interval. When the charging cable 4 is received in the vehicle shell 6, the photoelectric sensor detects the passage of the mark. When a specific number of marks are detected passing, it means that the charging cable 4 has been wound up to a set length. The photoelectric sensor transmits a signal to the control circuit, and the control circuit controls the winding motor 10 and the second motor 11 to stop rotating.

[0044] A first guide wheel 35 is provided in the vehicle shell 6 near the wire inlet 5. After the charging cable 4 is connected to the first guide wheel 35, it is connected to the second adjusting wheel 17; a second guide wheel 36 is provided in the vehicle shell 6 between the winding wheel 8 and the second adjusting component 15. After the charging cable 4 is connected to the second guide wheel 36, it is connected to the third adjusting wheel 25; a third guide wheel 37 is provided in the vehicle shell 6. After the charging cable 4 is connected to the fourth adjusting wheel 26, it is connected to the third guide wheel 37.

[0045] In one embodiment, the protective charging cart 2 is provided with a high-definition industrial camera, a laser radar, a millimeter-wave radar, and an ultrasonic sensor, and automatically identifies the position of the car or the charging port 13 through image recognition and positioning functions; the protective charging cart 2 is provided with a GPS positioning module and a guidance system. During driving, the automatic charging cart uses the environmental information obtained by the perception sensor to build a map and perform positioning in real time, and plans a safe and efficient driving path based on the car's location information and map data to guide the automatic charging cart to accurately reach the car's charging port 13. At the same time, the path can be updated in real time during driving to avoid obstacles and other vehicles and pedestrians; the protective charging cart 2 is provided with a vehicle-mounted controller to control the driving of the protective charging cart 2, and by setting a communication module, the protective charging cart 2 and the charging pile communicate to obtain the car's charging needs.

[0046] In one embodiment, a fixed track is set on the ground, and the protective charging cart 2 travels a fixed route on the fixed track. The fixed track is set on both sides of the parking space. After the charging vehicle is parked according to the parking space, the protective charging cart 2 travels along the fixed track to the vicinity of the vehicle.

[0047] During the use of the device, after the user sends a charging request, the charging pile controls the protective charging cart 2 to automatically move to the vicinity of the vehicle. During the process, the charging line 4 in the protective charging cart 2 needs to be gradually released. At this time, the charging line 4 is released by the reel 8. When the charging line 4 drags on the ground, the tension of the charging line 4 will change. The tension sensor can accurately measure the tension value of the cable and convert it into an electrical signal output, thereby controlling the first adjustment component 14 to tighten to prevent the cable from being dragged on the ground. The control process of the first adjustment component 14 is that the first motor 24 drives the first driving rod 21 to rotate, and the first push rod 22 and the second push rod 23 are used to adjust the tension of the first adjustment component 14. The first adjusting slider 18 and the second adjusting slider 19 perform a pushing action. When the first adjusting slider 18 and the second adjusting slider 19 move in opposite directions, the charging cable 4 is tightened, and then the charging cable 4 is placed on the ground to mop the ground. At the same time, since the charging cable 4 is released at both ends of the reel 8, in order to keep the other end unaffected, the charging cable 4 released at the other end is adjusted by the second adjusting component 15, and the second motor 11 drives the second driving rod 30 to rotate, and the third adjusting slider 27 and the fourth adjusting slider 28 are pushed by the third pushing rod 31 and the fourth pushing rod 32. When the third adjusting slider 27 and the fourth adjusting slider 28 move in opposite directions, the charging cable 4 is tightened.

[0048] Furthermore, when the protective charging vehicle 2 is moving, the charging line 4 can be directly controlled to relax by the first adjusting component 14, such as Figure 6 , providing margin for releasing the charging cable 4.

[0049] When charging is required, the user pulls out the charging gun, and after the tension sensor detects the pulling force, the control circuit controls the second adjustment component 15 to release the charging cable 4. Figure 7 Or the charging cables 4 on both sides are released through the reel 8, and the charging cables 4 on the other side are tightened through the first adjustment component 14.

[0050] When charging is completed, if the charging gun is not placed stably and falls, its gravity or acceleration will change significantly. The gravity sensor or acceleration sensor on the charging gun can quickly capture these change signals and convert them into electrical signal output, thereby controlling the second adjustment component 15 to tighten the charging cable 4 to achieve rapid cable reeling and prevent the charging gun from falling. After the charging gun is retracted, it enters the socket 33 and is limited. The tension sensor or photoelectric sensor is used to detect and stop the retraction of the charging cable 4.

[0051] Alternatively, the charging cable 4 can be quickly retracted by controlling the reel 8 to reel in, thereby preventing the charging gun from falling. Meanwhile, the other end of the reel 8 requires the first adjusting component 14 to loosen the charging cable 4 .

[0052] Furthermore, during use, the device automatically adjusts the tightness of the charging cable 4. When the charging cable 4 drags on the ground, the charging cable 4 is tightened in time to keep it suspended to avoid the cable dragging on the ground and causing damage to the charging cable 4. When the charging gun falls, the charging cable 4 is quickly recovered to prevent the charging gun from being bumped.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
