Description

Technical Field

[0001] The present invention relates to the field of charging piles, and more specifically, to a wall-mounted charging pile and a method for using the same. Background Art

[0002] A charging pile is a kind of energy supply facility that is compatible with new energy vehicles. It is generally divided into vertical and wall-mounted types. Vertical charging piles do not need to be against the wall and are suitable for outdoor parking spaces and community parking spaces, while wall-mounted charging piles must be fixed to the wall and are suitable for indoor and underground parking spaces. However, although wall-mounted charging piles must be fixed to the wall, their space occupancy rate is significantly smaller than that of vertical charging piles, so they are still widely used.

[0003] The positions of the charging sockets for existing new energy vehicles are not fixed. There are many types including left rear, right rear, and front. However, charging piles are generally fixed structures. At the same time, the space in indoor and underground parking spaces is relatively small compared to outdoor space, which is generally not convenient for adjusting the position of the vehicle. In addition, parking spaces generally restrict the placement of vehicles, making the relative position between the socket and the charging pile have many possibilities. As a result, when the owner parks the vehicle and charges the vehicle, it is necessary to pull the cable of the charging pile to the socket of the vehicle. At this time, the cable is often dragged on the ground, which is easy to cause the cable to be kicked or stepped on, which is not safe and is not conducive to the service life of the cable. Summary of the invention

[0004] In view of the deficiencies in the prior art, an object of the present invention is to provide a wall-mounted charging pile and a method for using the same.

[0017] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] Embodiment 1: A wall-mounted charging pile, such as Figure 1 , Figure 2 As shown, it includes a shell 1, a cable 2, and a charging gun 3. A plurality of fixing rings 4 are sleeved on the cable 2. The fixing rings 4 can rotate on the cable 2 and slide along the cable 2. A fixing device is provided on the side wall of the fixing ring 4, and the fixing device is detachably connected to the vehicle surface.

[0019] Specifically, one end of the cable 2 extends from the bottom surface of the shell 1, and the other end of the cable 2 is connected to the charging gun 3. The charging gun 3 is normally inserted into the side wall of the shell 1. In this embodiment, there are two fixing rings 4 on the cable 2, and the inner diameter of the fixing ring 4 is the same as the outer diameter of the cable 2. Compared with the prior art, the cable 2 in this embodiment can be positioned on the surface of the vehicle by the fixing ring 4 and the fixing device. Therefore, during use, the cable 2 is suspended above the ground, which reduces the contact between the cable 2 and people, reduces safety hazards and ensures the service life of the cable 2. At the same time, because the cable 2 can be fixed on the surface of the vehicle, there is no need to worry about the relative movement between the cable 2 and the vehicle causing damage to the vehicle surface. For some vehicles where the socket and the charging pile are on both sides of the vehicle, the cable 2 can directly cross the vehicle to reach the socket, shortening the length requirement of the cable 2 and saving costs.

[0020] like Figure 1-Figure 4 As shown, the fixing device includes a suction cup 5, which adsorbs to the vehicle surface by generating negative pressure inside the suction cup 5, and also includes a power supply module and a control module. The fixing device also includes a pumping mechanism 6, the inner cavity of the suction cup 5 is connected to the pumping mechanism 6, the power supply module is used to supply power to the pumping mechanism 6, and the control module is communicatively connected with the pumping mechanism 6.

[0021] Specifically, a flow channel connected to the pumping mechanism 6 is opened at the center of the suction cup 5. The pumping mechanism 6 draws out part of the air between the vehicle surface and the suction cup 5 through a piston structure, so that a negative pressure relative to the outside world is generated between the vehicle surface and the suction cup 5, and then the suction cup 5 is pressed against the surface of the vehicle by the pressure of the outside world. The structure of the suction cup 5 can adapt to the bottom or side of the vehicle to ensure that the cable 2 can reach the socket of the vehicle along a shorter path. The control module can remotely control the pumping mechanism 6 to open or close. When the fixing ring 4 is located in the middle of the vehicle, making it difficult for the operator to contact the fixing ring 4, the suction cup 5 can also be smoothly controlled to be fixed on the surface of the vehicle.

[0022] like Figure 1-Figure 3 As shown, the control system includes a transmitter and a control button 9, both of which are located on the charging gun 3. The fixing device also includes an indicator light 10 and an automatic air pressure switch. The automatic air pressure switch is connected to the inner cavity of the suction cup 5, and the automatic air pressure switch is used to control the indicator light 10 to turn on and off.

[0023] Specifically, the transmitter and the control button 9 are both located on the charging gun 3, which is convenient for the user to control the suction cup 5 before inserting and removing the charging gun 3. The control button 9 adopts a self-locking switch structure, which is convenient for the operator to judge the triggering state of the extraction mechanism 6. The control switch is located at the bottom of the charging gun 3. The bottom of the charging gun 3 is provided with a accommodating cavity for accommodating the control button 9, and the bottom of the charging gun 3 is rotatably connected with a protective cover to prevent accidental touching of the control button 9. When necessary, the protective cover can be opened to expose the control button 9. After completing the operation, buckle the protective cover to avoid the transmitter from triggering unnecessary instructions due to accidental triggering. The air pressure automatic switch is connected to the flow channel. The air pressure automatic switch can control the on and off of the indicator light 10 according to whether the air pressure feedback circuit is turned on. When the indicator light 10 is on, it means that negative pressure is generated between the vehicle surface and the suction cup 5, so that the operator can judge whether the suction cup 5 has been fixed on the vehicle surface.

[0024] like Figure 1-Figure 4 As shown, the fixing device also includes a charging port and a cover plate 7 covering the charging port. The power supply module is composed of a plurality of charging cables 8 located on the bottom surface of the shell 1. One end of the cable 2 is located on the bottom surface of the shell 1. A counterweight ring 11 is fixedly connected to the outer wall of the suction cup 5, and the counterweight ring 11 is covered with a rubber sleeve.

[0025] Specifically, the cover plate 7 is rotatably connected to the fixing ring 4, and one end of the cover plate 7 away from the rotation axis protrudes outward, which is convenient for lifting the cover plate 7. Under normal circumstances, the cover plate 7 covers the charging port to prevent foreign debris from entering the charging port. The number of charging cables 8 is the same as the number of charging ports. The charging cable 8 is located at the bottom end of the shell 1, and one end of the cable 2 is also located at the bottom end of the shell 1. Therefore, the fixing ring 4 can be moved to the bottom end of the shell 1 along the cable 2, shortening the distance between the fixing ring 4 and the charging cable 8, and facilitating the connection of the charging cable 8 with the charging port. Under normal circumstances, the plug part of the charging cable 8 is inserted into the bottom end of the shell 1, which protects the charging cable 8 and ensures the service life of the charging cable 8. The fixing ring 4 is divided into an inner ring and an outer ring, and the inner ring and the outer ring rotate with each other. A counterweight ring 11 is sleeved on the outer wall of the suction cup 5, thereby ensuring that the suction cup 5 has a tendency to rotate to the lowest end of the fixing ring 4, so that the suction cup 5 can contact the vehicle surface. The counterweight ring 11 is wrapped with a rubber sleeve, and the rubber sleeve plays a buffering role between the vehicle surface and the suction cup 5 to avoid damaging the vehicle surface.

[0026] Embodiment 2: A method for using a wall-mounted charging pile, applied to the above-mentioned wall-mounted charging pile, comprising a fixing step and a disassembly step; Fixing steps: S11, adjusting the position of the fixing ring 4 and the orientation of the suction cup 5; S12, remove the charging gun 3 from the housing 1, and bring the charging gun 3 to the socket of the vehicle; S13, lift the cable 2 so that the suction cup 5 contacts the surface of the vehicle; S14, pressing the control button 9, the pumping mechanism 6 which receives the signal from the transmitter creates a negative pressure environment on the suction cup 5, so that the suction cup 5 is fixed on the surface of the vehicle; Disassembly steps: S21, pressing the control button 9 to make the control button 9 pop up, and the pumping mechanism 6 receiving the signal from the transmitter increases the air pressure between the suction cup 5 and the vehicle surface, thereby releasing the fixation of the suction cup 5 and the vehicle; S22, remove the charging gun 3 from the vehicle, and insert the charging gun 3 into the housing 1; S23, adjusting the position of the fixing ring 4 and the direction of the charging port; S24, connecting the charging cable 8 to the charging port.

[0027] In S14, the indicator light 10 is used to determine whether the suction cup 5 has been fixed to the vehicle.

[0028] Specifically, in the fixing step, the position of the fixing ring 4 and the direction of the suction cup 5 are preliminarily adjusted. Because the fixing method of the suction cup 5 can be sucked on most surfaces of the vehicle, there is no need to accurately position the fixing ring 4. The charging gun 3 is brought to the socket of the vehicle, and the cable 2 is adjusted so that the cable 2 crosses the vehicle. At the same time, the suction cup 5 rotates relative to the inner ring together with the outer ring. When the cable 2 is lowered, the suction cup 5 is attached to the surface of the vehicle. When the control button 9 is pressed, the transmitter sends a signal to the pumping mechanism 6 to make the suction cup 5 sucked on the vehicle. At this time, if the suction cup 5 successfully completes the adsorption, the indicator light 10 will light up to prevent the cable 2 from moving on the surface of the vehicle due to the failure of the suction cup 5 to complete the adsorption. In the disassembly step, before unplugging the charging gun 3, a signal is first sent to the pumping mechanism 6. The pumping mechanism 6 presses air into the inner cavity of the suction cup 5, and the suction cup 5 falls off the surface of the vehicle. After placing the charging gun 3, the fixing ring 4 is moved to the bottom of the shell 1, and the charging cable 8 is inserted into the charging port to charge the pumping mechanism 6.

[0029] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
