Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle charging equipment, and in particular to a supporting bracket for facilitating the use of a charging gun. Background Art

[0002] The core mission of new energy charging is to convert the power of the power grid into direct current or alternating current suitable for electric vehicles through safe and efficient power conversion, so as to provide power supply for electric vehicles. The charging pile can automatically detect the battery status to avoid safety hazards such as overcharging and over-discharging. At the same time, it also has multiple protection functions such as overload protection and overvoltage protection to ensure the safety and reliability of the charging process. The charging pile is mainly composed of an external box, a power distribution module arranged inside the box, and an external charging cable and a charging gun. When the car owner needs to charge, he needs to park the vehicle near the charging pile, and then pull the charging gun out of the placement port and install it on the charging port of the car. After charging, the charging gun needs to be put back into the placement port. It has been reported that some car owners did not put the charging gun back to the designated position after charging, but placed it at random, or even directly on the ground, which greatly reduced the service life of the charging pile and the safety of subsequent use. At present, there are public patents for the design of recyclable charging cables and gun bodies, such as (application number 202322638376.2 A charging gun cable transceiver, charging terminal and charging station). The defect of this patent is that the charging cable pulls the gun body to be recovered during recycling, and the charging gun body always rubs against the ground during the charging process, which is easy to cause irreversible damage to the charging gun body and needs to be improved. Therefore, we propose a supporting bracket for facilitating the use of a charging gun. Summary of the invention

[0003] The purpose of the present invention is to provide a supporting bracket for facilitating the use of a charging gun, thereby solving the problems raised in the background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a supporting bracket for facilitating the use of a charging gun, comprising a charging pile, a charging cable and a charging gun, a support fixedly installed on the top of the charging pile, a rotating structure, a proximity sensor and a hanging wheel mechanism are sequentially installed on the bottom surface of the support from left to right, a sleeve is rotatably installed on the bottom of the rotating structure, the charging cable passes through the hanging wheel mechanism and the sleeve sequentially from right to left, a climbing buckle is fixedly provided on the inner wall of the sleeve, a circular plate is fixedly provided on the outer wall surface of the charging cable, one side of the circular plate is fixedly connected to one end of a spring, and the other end of the spring is fixedly provided with a clamping ring engaged with the climbing buckle.

[0005] As a preferred implementation of the technical solution of the present application, the circular plate is inlaid and slidably arranged inside the sleeve, and the diameter of the circular plate is 2 mm smaller than the diameter of the inner hole of the sleeve.

[0006] As a preferred implementation scheme of the technical solution of the present application, the rotating structure includes an arc connecting seat, an axis body and a flange seat. The arc connecting seat is rotatably connected to the flange seat through the axis body. The arc connecting seat is fixed to the outer circumferential surface of the sleeve, and the flange seat is fixed to the bottom surface of the support.

[0007] As a preferred implementation of the technical solution of the present application, the hanging wheel mechanism includes a hanging wheel frame and a hanging wheel. The hanging wheel is rotatably installed on the inner side of the hanging wheel frame through a central axis, and an arc groove is opened in the middle of the hanging wheel to be embedded with the charging cable.

[0008] As a preferred implementation of the technical solution of the present application, a buzzer is fixedly provided on the surface of one side of the charging pile, and the buzzer and the proximity sensor are both electrically connected to the controller.

[0009] As a preferred implementation of the technical solution of the present application, the area after the charging cable passes through the hanging wheel mechanism and before entering the inside of the sleeve is the U-shaped pendant area of ​​the charging cable, and the proximity sensor is vertically aligned with the U-shaped pendant area of ​​the charging cable.

[0010] As a preferred implementation of the technical solution of the present application, the support includes a top flat plate seat and a reinforcing rib seat, and the reinforcing rib seat is fixed to the top of the charging pile.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The technical solution of the present application realizes the elastic extension and retraction of the charging cable by cooperating with a circular plate, a spring, a clamp ring, and a climbing buckle of a sleeve, and the charging cable is suspended. After charging is completed, the car owner can directly discard the charging gun in time, and the charging gun will not directly hit the ground. Instead, the charging cable retracts to drive the charging gun to rise, so that the car owner can let go after unplugging the charging gun. There is no need to put the charging gun back in place intact like a traditional charging pile, which improves the convenience of use and increases the service life of the charging gun.

[0012] 2. The technical solution of the present application monitors the elongation margin of the charging cable through a proximity sensor. When the charging cable reaches the elongation limit, the proximity sensor will monitor the charging cable and start the buzzer to alarm through the controller, thereby achieving the function of preventing the charging cable from extreme pulling. The charging gun can be flexibly adjusted in position through the rotating structure, thereby adapting to the vehicle charging scenarios with the charging port on the left and right sides.

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] Embodiment 1, as Figure 1-4 As shown, the present invention provides a technical solution: a supporting bracket for facilitating the use of a charging gun, comprising a charging pile 1, a charging cable 3 and a charging gun 5, a support 9 is fixedly installed on the top of the charging pile 1, a rotating structure 6, a proximity sensor 7 and a hanging wheel mechanism 8 are sequentially installed on the bottom surface of the support 9 from left to right, a sleeve 4 is rotatably installed on the bottom of the rotating structure 6, the charging cable 3 passes through the hanging wheel mechanism 8 and the sleeve 4 from right to left, a climbing buckle is fixedly provided on the inner wall of the sleeve 4, a circular plate 10 is fixedly provided on the outer wall surface of the charging cable 3, one side of the circular plate 10 is fixedly connected to one end of a spring 11, and the other end of the spring 11 is fixedly provided with a clamping ring 12 clamped with the climbing buckle.

[0017] In a specific embodiment of the present invention, the rotating structure 6 includes an arc connection seat 601, a shaft body 603 and a flange seat 602. The top of the shaft body 603 is tightly connected to the flange seat 602, the bottom of the shaft body 603 passes through the arc connection seat 601 and the bottom is limited by a clamp. A bearing is provided at the point where the shaft body 603 and the arc connection seat 601 pass through, which is used for the rotation of the arc connection seat 601. The circular plate 10 provided on the surface of the charging cable 3 is embedded in the middle position inside the sleeve 4, and the carabiner of the sleeve 4 is located on the right side. After the clamp 12 of the spring 11 cooperates with the carabiner, when the charging cable 3 is stretched, the spring 11 is in a stretched state. When the charging gun 5 is released, the resilience of the spring 11 causes the charging cable 3 to retract to the right along the inside of the sleeve 4, thereby lifting the charging gun 5 to prevent the charging gun 5 from falling to the ground. When the spring 11 is in a naturally stretched state, the area after the charging cable 3 passes through the hanging wheel mechanism 8 and before entering the sleeve 4 is the U-shaped pendant area of ​​the charging cable 3 (such as Figure 1As shown), at this time, the proximity sensor 7 cannot detect the charging line 3 in the U-shaped pendant area, and the buzzer 2 is in silent state. When the charging gun 5 is pulled, the charging line 3 moves along the left side of the sleeve 4, and the U-shaped pendant area gradually rises until the U-shaped pendant area is straightened. At this time, the charging line 3 is in the extreme straightening state. At this time, the proximity sensor 7 detects the charging line 3, and the controller processes the signal of the proximity sensor 7 and turns on the buzzer 2 for warning.

[0018] In the preferred technical solution, the circular plate 10 is embedded and slidably arranged inside the sleeve 4 , and the diameter of the circular plate 10 is 2 mm smaller than the inner hole diameter of the sleeve 4 , so that the circular plate 10 can slide smoothly inside the sleeve 4 .

[0019] In the preferred technical solution, the rotating structure 6 includes an arc connecting seat 601, a shaft body 603 and a flange seat 602. The arc connecting seat 601 is rotatably connected to the flange seat 602 through the shaft body 603. The arc connecting seat 601 is fixed to the outer circumferential surface of the sleeve 4, and the flange seat 602 is fixed to the bottom surface of the support 9. The rotating structure 6 is used to realize the rotation of the sleeve 4. The charging gun 5 can be flexibly adjusted in position through the rotating structure 6 to adapt to the vehicle charging scenarios with the charging port on the left and right sides.

[0020] In the preferred technical solution, the hanging wheel mechanism 8 includes a hanging wheel frame 801 and a hanging wheel 802. The hanging wheel 802 is installed on the inner side of the hanging wheel frame 801 by rotating through the central axis. An arc groove 803 is provided in the middle of the hanging wheel 802 to be embedded with the charging cable 3. The hanging wheel mechanism 8 is used to guide the charging cable 3 to bend in an arc shape, thereby reducing the probability of bending, breaking and damage of the charging cable.

[0021] In the preferred technical solution, a buzzer 2 is fixedly provided on the surface of one side of the charging pile 1. The buzzer 2 and the proximity sensor 7 are electrically connected to the controller. The proximity sensor 7 monitors the charging line 3. The controller processes the signal of the proximity sensor 7, indicating that the charging line 3 is in an extreme straightening state. Continuing to pull the charging gun 5 will cause damage to the charging line 3, and the buzzer 2 is turned on for warning.

[0022] In the preferred technical solution, the area after the charging cable 3 passes through the hanging wheel mechanism 8 and before entering the sleeve 4 is the U-shaped pendant area of ​​the charging cable 3, and the proximity sensor 7 is vertically aligned with the U-shaped pendant area of ​​the charging cable 3. The U-shaped pendant area is used as a detection point when the charging cable 3 is in an extreme straightened state.

[0023] In the preferred technical solution, the support 9 includes a top flat plate seat and a reinforcing rib seat, the reinforcing rib seat is fixed to the top of the charging pile 1, and the reinforcing rib seat is used to improve the supporting performance of the support 9.

[0024] Working principle: Under normal circumstances, the charging gun 5 is 1.2m away from the ground, the spring 11 is in a naturally stretched state, and the U-shaped pendant area of ​​the charging cable 3 (such as Figure 1 As shown in the figure, the buzzer 2 is in silent state. When the charging gun 5 is pulled to make the charging line 3 move along the left side of the sleeve 4, the U-shaped pendant area gradually rises until the U-shaped pendant area is straightened. At this time, the charging line 3 is in the extreme straightening state. At this time, the proximity sensor 7 detects the charging line 3, and the controller processes the signal of the proximity sensor 7 and turns on the buzzer 2 for warning. Normal use of the charging gun 5 only requires aligning the charging gun 5 with the charging port of the vehicle. If the charging gun 5 and the charging port of the vehicle are not on the same side, since the sleeve 4 can be rotated, the charging gun 5 can be easily moved to the same side as the charging port of the vehicle. When the charging gun 5 cooperates with the vehicle charging, the spring 11 is in a stretched state. When the charging gun 5 is released, the resilience of the spring 11 causes the charging line 3 to retract to the right along the inside of the sleeve 4, thereby lifting the charging gun 5 to prevent the charging gun 5 from falling to the ground.
