Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and in particular to a protective auxiliary device for V2G bidirectional charging piles. Background Technology

[0002] V2G bidirectional charging piles support bidirectional interaction between electric vehicles and the power grid, enabling charging and energy storage during off-peak hours and reverse power supply during peak hours. Vehicle owners can earn income through the difference between peak and off-peak electricity prices, while the power grid improves its flexibility and stability, promoting efficient energy use and the consumption of renewable energy.

[0003] Using V2G bidirectional charging stations allows electric vehicles to feed excess electricity back to the grid when they are not in use, alleviating peak electricity demand. At the same time, car owners can earn income from the price difference in electricity, reducing the cost of car ownership. It can also promote the consumption of renewable energy and improve grid flexibility and energy efficiency.

[0004] Currently, after the charging gun is inserted into the device, the dangling cable exerts a continuous downward pull on the connection between the gun body and the interface due to its own weight. Over time, this can cause it to loosen and fall, leading to multiple hidden dangers. The fallen charging gun and cable are easily run over by vehicles or stepped on by pedestrians, causing damage to the insulation layer and posing a risk of leakage or short circuit. In addition, loosening can also result in the charging gun not being locked, which not only shortens the service life of the equipment and increases maintenance costs, but also causes electric shock accidents due to accidental contact, posing a safety threat to users and the surrounding environment.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example 1: Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a protective auxiliary device for V2G bidirectional charging piles, including a device body 1. The electrical output end of the device body 1 is electrically connected to a cable 2. The electrical output end of the cable 2 is fixedly connected to a charging gun 3. A frame 4 is fixedly connected to the inner wall of the device body 1. A positioning component 5 is provided at one end of the charging gun 3. A reset component 6 is provided on one side of the positioning component 5. A fixing post 12 is fixedly connected to the inner wall of the frame 4. The fixing post 12 is made of rubber. A pressure sensor body 13 is fixedly connected to one end of the fixing post 12. One side of the pressure sensor body 13 abuts against one end of the charging gun 3.

[0025] The main body 1 is used to install all components. The cable 2 connects the main body 1 and the charging gun 3. The cable 2 is used to transmit power to realize vehicle charging and discharging. The charging gun 3 is inserted into the vehicle charging interface to complete power transmission, which is convenient for users to plug and unplug. The frame 4 provides installation space for the positioning component 5, the reset component 6 and the fixing post 12, which facilitates the coordinated work of each component. The fixing post 12 is made of rubber, which can buffer the impact force when the charging gun 3 is inserted and protect the gun head. The pressure sensor body 13 is against one end of the charging gun 3 to sense whether the charging gun 3 is inserted firmly and remind the user to adjust it in time if it is not inserted firmly.

[0026] It should be noted that the pressure sensor body 13 is an FSR402 thin-film pressure sensor, which is adapted to the narrow space of the frame 4 and fits snugly against the rubber fixing post 12 without affecting the insertion of the charging gun 3. The pressure sensor body 13 fits against one end of the charging gun 3. When the charging gun 3 is inserted into the charging gun, the charging gun 3 squeezes the sensor to generate pressure. The pressure sensor body 13 converts the pressure signal into an electrical signal. If it is not inserted tightly, the pressure is insufficient, and the electrical signal will change. This signal can be linked with the indicator light or buzzer of the charging pile to remind the user to reinsert the gun. The rubber fixing post 12 plays a buffering role, which protects the pressure sensor body 13 and ensures accurate detection, preventing the charging gun 3 from loosening and falling.

[0027] The positioning component 5 includes a rubber ring 51 installed on the outside of the charging gun 3, and multiple sets of rubber rings 51 are provided. A clamping ring 52 is fixedly connected to the outside of the rubber ring 51, and the clamping ring 52 is made of rubber. A mounting block 53 is fixedly connected to one side of the clamping ring 52.

[0028] The rubber ring 51 fits against the outside of the charging gun 3 to increase friction, which facilitates positioning and protects the gun body. The clamping ring 52 wraps around the rubber ring 51 to further fix the charging gun 3 and prevent it from wobbling left and right. The mounting block 53 is used to connect the clamping ring 52 and the reset component 6 to facilitate the transmission of locking force.

[0029] The reset assembly 6 includes a connecting post 61 fixed to the upper end of the mounting block 53, a hook spring 62 is attached to the inner wall of the connecting post 61, and the other end of the hook spring 62 is attached to the mounting post 63.

[0030] The connecting post 61 is used to attach the hook spring 62, so that the hook spring 62 can exert force to pull the mounting block 53. The hook spring 62 is used to provide continuous pulling force to drive the clamping ring 52 to tighten, so as to automatically lock the charging gun 3. The mounting post 63 fixes one end of the hook spring 62, so that the hook spring 62 can maintain tension.

[0031] It should be noted that the hook spring 62 is made of 65Mn spring steel, which has good elasticity and fatigue resistance, and is suitable for the force requirements of frequent insertion and removal.

[0032] Example 2: This is the second embodiment of the present invention, which is based on the previous embodiment.

[0033] Specifically, one end of the mounting column 63 is rotatably connected to the mounting base 7, and one side of the mounting base 7 is fixedly connected to the connecting block 8.

[0034] Mounting base 7 provides rotational support for mounting column 63, and connecting block 8 supports and fixes mounting base 7, thereby making mounting base 7 more stable.

[0035] Specifically, one end of the connecting block 8 is fixedly connected to the support block 9, and one side of the support block 9 is fixedly connected to the inner wall of the frame 4.

[0036] Support block 9 is used to support mounting block 53 and connecting block 8, so that each component remains in a stable position.

[0037] Specifically, the inner wall of the mounting block 53 is rotatably connected to a connecting post 10, and one end of the connecting post 10 is rotatably connected to the inner wall of the support block 9.

[0038] The connecting post 10 is used to connect the mounting block 53 and the support block 9, so that the mounting block 53 can rotate flexibly, thereby driving the clamping ring 52 to be installed and disassembled.

[0039] Example 3: This is the third embodiment of the present invention, which is based on the first two embodiments.

[0040] Specifically, an elastic protective sleeve 11 is provided at the connection between the charging gun 3 and the cable 2 to protect one end of the cable 2.

[0041] The elastic protective sleeve 11 is placed at the connection between the charging gun 3 and the cable 2 to prevent the cable 2 from bending and wearing out, thus extending the service life of the cable 2.

[0042] Specifically, a winding roller 14 for winding the cable 2 is provided on one side of the device body 1, and a horizontal plate 15 is fixedly connected to one side of the device body 1.

[0043] The take-up roller 14 is used to take up the cable 2, which helps to prevent the cable 2 from scattering and being dragged. The cross plate 15 is used to fix the hanging plate 16, making the hanging plate 16 more stable when in use.

[0044] Specifically, a hanging hole plate 16 is fixedly connected to the top of the horizontal plate 15, and the inner wall of the hanging hole plate 16 is provided with screw holes arranged in an array. One side of the winding roller 14 is fixedly connected to one side of the hanging hole plate 16 by bolts.

[0045] The mounting plate 16 is fixed to the take-up roller 14 by bolts, and the position of the bolt holes is adjustable to accommodate the take-up needs of cables 2 of different lengths.

[0046] When in use, when the user needs to charge, they manually hold the charging gun 3 and pull it outwards. The pulling force causes the charging gun 3 to slide out along the inner wall of the rubber ring 51. The clamping ring 52 rotates around the connecting post 10 via the mounting block 53 until the charging gun 3 is removed and resets. As the charging gun 3 is pulled out, the pressure sensor body 13 loses the pressure of the charging gun 3, the pressure signal disappears, and the device defaults to the use state without issuing a reminder. At the same time, as the user pulls out the charging gun 3, the cable 2 is released synchronously from the winding roller 14. The elastic protective sleeve 11 moves flexibly with the cable 2 to avoid wear at the connection of the cable 2. The winding roller 14 can be adjusted in position through different screw holes on the hanging plate 16 to adapt to the length of the cable 2 pulled out, ensuring that the cable 2 is not taut or dragged when the user is charging. After charging is completed, the user inserts the charging gun 3 into the mounting position of the frame 4. The rubber ring 51 and clamping ring 52 in the positioning component 5 play a guiding role. During the insertion process, when the charging gun 3 is inserted into the rubber ring 51, the two sets of The circular groove formed by the rubber ring 51 and the clamping ring 52 will expand outwards, and the hook spring 62 will be stretched to generate elastic force. The mounting block 53 rotates around the connecting post 10 until it is inserted into one side of the pressure sensor body 13. The reset tension of the hook spring 62 is converted into clamping force, which drives the clamping ring 52 to tighten and cooperate with the rubber ring 51 to firmly fix the charging gun 3 and prevent it from wobbling left and right. If the user does not fully insert the charging gun 3 into the frame 4, the charging gun 3 cannot fully squeeze the pressure sensor body 13. The pressure sensor body 13 detects insufficient pressure, and the electrical signal changes. This signal is linked to the indicator light or buzzer of the charging pile to emit flashing light or alarm sound to remind the user that the charging gun 3 is not inserted tightly. At this time, the clamping ring 52 has not reached the optimal locking state, and the charging gun 3 is at risk of loosening. After receiving the reminder, the user re-inserts the charging gun 3 into place. The pressure sensor body 13 senses stable pressure, the electrical signal returns to normal, and the reminder stops, ensuring that the charging gun 3 is firmly fixed.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
