Abstract
Description
Technical Field
[0001] This utility model relates to the field of charging pile protection technology, and in particular to a power failure protection device for new energy vehicle charging piles. Background Technology
[0002] If thunderstorms occur during charging, lightning may damage the charging equipment. Therefore, if a thunderstorm occurs after the vehicle has finished charging and no one is nearby, the vehicle controller should be notified to disconnect the charging status according to the rainfall situation to protect the vehicle and the charging equipment.
[0003] Chinese Patent CN220639570U discloses an automatic power-off protection device for new energy vehicle charging during thunderstorms, including a charging pile and a detection base. A top base is fixedly installed on the top side of the charging pile. The main body of the top base is a shield, which is an inverted V-shaped shield with an inverted V-shaped liquid groove. A side base is fixedly installed at the bottom of the shield, and a conduit is fixedly connected to the output end of the side base, with the outer end of the conduit inserted into the detection base. A detection cylinder is fixedly installed on the inner side of the detection base, and an electromagnetic float is placed inside the detection cylinder. This automatic power-off protection device for new energy vehicle charging during thunderstorms collects rainwater through the liquid groove on the top side of the top base and transports it through the side base and conduit to the detection cylinder inside the detection base. The electromagnetic float, affected by the rainwater, floats up and down inside the detection cylinder. This causes the electromagnetic float to generate an induced electromotive force with an electromagnetic inductor inside the detection cylinder, producing a weak current signal, which in turn controls the device to cut off power.
[0004] The shortcomings of the above-mentioned existing technical solutions are as follows: the rainwater collected by the liquid tank on the top side of the top seat enters the detection mechanism through the liquid inlet hole set on the side seat and the connecting pipe. The liquid inlet hole set on the top is easily blocked by fallen leaves and other debris, making it impossible for rainwater to enter the detection mechanism. The device is prone to failure in thunderstorms, making the power-off operation not timely enough, failing to play an effective protection role, and causing economic losses to users. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a power outage protection device for new energy vehicle charging piles, thereby resolving the problems existing in the prior art.
[0006] According to a first aspect of this utility model, a power outage protection device for a new energy vehicle charging pile is provided, comprising:
[0007] The charging pile has a detection mechanism fixedly installed on its side and a top seat fixedly connected to its upper end. The top seat includes a baffle and a fixed seat fixedly connected to the lower end of the baffle. Liquid grooves are evenly distributed and opened on the upper surface of the baffle. Side grooves connected to the liquid grooves are opened on the fixed seat and are connected to the detection mechanism.
[0008] The connecting mechanism includes a connecting body, a connecting groove on the connecting body, the connecting mechanism being fixedly installed in a side groove, the side groove and the connecting groove being connected, and connecting holes evenly distributed and penetrating on the connecting body, each corresponding to a liquid tank, the connecting holes being connected to the connecting groove.
[0009] As a further embodiment of this utility model: the main body is arranged in a long strip shape, and a protective net is fixedly connected to each connecting hole, and a protective plate is fixedly connected to the opening edge of the connecting hole.
[0010] As a further embodiment of this utility model: a connecting hole is provided on the bottom surface of the side groove, and a connecting pipe is provided between the detection mechanism and the top seat.
[0011] As a further embodiment of this utility model: one end of the connecting pipe is connected to the side groove through a connecting hole, and the other end of the connecting pipe is connected to the detection mechanism.
[0012] As a further embodiment of this utility model: the detection mechanism includes a detection cylinder and an electromagnetic buoy, with the electromagnetic buoy disposed inside the detection cylinder.
[0013] As a further embodiment of this utility model: the baffle is arranged in an inverted V shape, and the extension trajectory of the liquid tank is inverted V shape.
[0014] As a further embodiment of this utility model: the bottom surface of the charging pile is provided with a base to fix the entire device, and the side end of the charging pile is provided with a charging gun for charging.
[0015] The beneficial effects of this utility model are:
[0016] In thunderstorms, this invention features a shield and liquid tank for rapid rainwater collection. Rainwater enters the connecting tank through the connecting hole, then flows through the connecting hole and connecting pipe into the detection mechanism. The detection mechanism controls the rotating device to automatically cut off power. A protective net prevents foreign objects from entering the connecting tank through the connecting hole, and a protective plate prevents foreign objects from clogging the protective net, facilitating rapid rainwater passage. Simultaneously, the connecting mechanism covers the side tank, preventing the accumulation of foreign objects within the side tank. Compared to existing technologies that only connect the top seat and detection mechanism through a top-opening liquid inlet, the connecting mechanism's connecting holes correspond one-to-one with the liquid tank. This design creates multiple pathways between the top seat and the detection mechanism, effectively preventing foreign objects from clogging the connecting hole and side tank. This allows rainwater to quickly reach the detection mechanism during thunderstorms, preventing malfunctions that could lead to delayed power-off operations and providing effective protection against economic losses for the user.

[0026] Reference Figures 1 to 4This utility model provides a power failure protection device for a new energy vehicle charging pile, including a charging pile 2 and a connecting mechanism 7. A detection mechanism 4 is fixedly installed on the side of the charging pile 2. A top seat 6 is fixedly connected to the upper end of the charging pile 2. The top seat 6 includes a baffle 61. A fixing seat 63 is fixedly connected to the lower end of the baffle 61. Liquid grooves 62 are evenly distributed and formed on the upper surface of the baffle 61. A side groove 64 communicating with the liquid grooves 62 is formed on the fixing seat 63. The side groove 64 is connected to the detection mechanism 4. The connecting mechanism 7 includes a connecting body 71. A connecting groove 72 is formed on the connecting body 71. The connecting mechanism 7 is fixedly installed in the side groove 64, and the side groove 64 is connected to the connecting groove 72. The connecting body 71 has evenly distributed and through-holes 73 that correspond one-to-one with the liquid tank 62. The connecting holes 73 are connected to the connecting groove 72. The connecting body 71 is generally elongated. A protective net 74 is fixedly connected to each connecting hole 73. A protective plate 75 is fixedly connected to the opening edge of the connecting hole 73. By setting the protective net 74, foreign objects can be prevented from entering the connecting groove 72 through the connecting hole 73. The protective plate 75 can prevent foreign objects from blocking the protective net 74 and facilitate the entry of rainwater.
[0027] A connection hole 65 is provided on the bottom surface of the side groove 64. A connecting pipe 5 is provided between the detection mechanism 4 and the top seat 6. One end of the connecting pipe 5 is connected to the side groove 64 through the connection hole 65, and the other end of the connecting pipe 5 is connected to the detection mechanism 4. The detection mechanism 4 includes a detection cylinder and an electromagnetic float. The electromagnetic float is set inside the detection cylinder, and the connecting pipe 5 is connected to the detection cylinder. When rainwater enters the detection cylinder, the electromagnetic float floats up and down inside the detection cylinder due to the influence of the rainwater. The electromagnetic float will generate an induced electromotive force with the electromagnetic inductor set inside the detection cylinder, generating a weak current signal, which will then control the device to automatically cut off the power for protection.
[0028] In some specific embodiments, the baffle 61 is arranged in an inverted V shape, and the extension trajectory of the liquid tank 62 is inverted V shape. The inverted V-shaped baffle 61 and liquid tank 62 facilitate the collection of rainwater.
[0029] In some specific embodiments, the bottom surface of the charging pile 2 is provided with a base 1 to fix the entire device, and the side end of the charging pile 2 is provided with a charging gun 3 for charging.
[0030] Workflow:
[0031] During thunderstorms, the inverted V-shaped baffle 6 and liquid tank 62 facilitate rapid rainwater collection. Rainwater enters the connecting channel 72 through the connecting hole 73, then passes through the connecting hole 65 and connecting pipe 5 into the detection mechanism 4. The detection mechanism 4 controls the rotating device to automatically cut off power. A protective net 74 prevents foreign objects from entering the connecting channel 72 through the connecting hole 73, and a protective plate 75 prevents foreign objects from blocking the protective net 74, allowing rainwater to pass through quickly. At the same time, the connecting mechanism 7 covers the side channel 64 to prevent foreign objects from accumulating inside the side channel 64. Compared to existing technologies that connect the top seat 6 and the detection mechanism 4 only through a liquid inlet hole with an open top, the connecting mechanism 7 has a connecting hole 73 on the connecting body 71 that corresponds one-to-one with the liquid tank 62. The connecting mechanism 7 provides multiple pathways between the top seat 6 and the detection mechanism 4, and can effectively prevent foreign objects from clogging the connecting hole 65 and the side tank 64. This allows rainwater to quickly reach the detection mechanism 4 during thunderstorms, preventing malfunctions during thunderstorms that could lead to untimely power-off operations, thus providing effective protection and preventing economic losses for the user.
