Description

Technical Field

[0001] The utility model belongs to the technical field of energy storage, and in particular relates to a DC charging pile hanging gun socket with an indication function. Background Art

[0002] With the popularization of new energy vehicles, the demand for charging piles is also increasing day by day, especially DC charging piles, which have been widely used due to their advantages such as fast charging, high energy utilization and high compatibility.

[0003] However, most existing DC charging piles do not have a gun hanging status prompt function. After the user hangs the charging gun, he cannot know whether it is completely hung. This makes it easy for the charging gun to fall, causing damage or causing safety accidents. Some charging piles have a prompt for the completion of the gun hanging, but the triggering conditions are not stable. For example, when using a pressure sensor to judge the triggering conditions, it is possible that the pressure at the time of hanging the gun meets the triggering conditions, but the actual hanging gun is not firm. After that, the charging gun gradually loosens, which still creates safety hazards.

[0004] Therefore, a DC charging pile hanging gun socket with an indication function and a reliable hanging gun is needed. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides a DC charging pile gun socket with an indication function, including a gun body socket, a normally open switch device, a relay and a gun hanging status indication module, the gun body socket having an inner surface, a switch slot being provided on the inner surface, a trigger mechanism of the normally open switch device passing through the switch slot and exposed on the inner surface, and the relay being electrically connected to the normally open switch device and the gun hanging status indication module respectively.

[0006] When the charging gun is hung, the charging gun touches the trigger mechanism, closing the normally open switch device and triggering the relay, which controls the hanging gun status indication module to work.

[0007] Preferably, the gun-hanging state indication module includes an indicator light, which is arranged on the surface of the DC charging pile gun-hanging socket, and the indicator light is electrically connected to the relay.

[0008] Preferably, the gun hanging state indication module includes a voice prompt module, and the voice prompt module is electrically connected to a relay.

[0009] Preferably, the normally open switch device is a micro switch.

[0010] Preferably, the switching stroke of the micro switch is 1.5 mm.

[0011] Preferably, it further comprises a locking mechanism, which is arranged on the socket of the gun body and is adapted to the setting position of the trigger mechanism.

[0012] Preferably, when the charging gun is locked with the locking mechanism, the charging gun touches the trigger mechanism, and the trigger mechanism can just close the normally open switch device.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The utility model forms a simple and efficient indication function by setting a normally open switch device, a relay, and a gun hanging state indication module.

[0015] (2) The utility model makes the triggering method simpler and more reliable by coordinating the normally open switch device with the locking mechanism. The normally open switch device and the locking mechanism are coordinating. It is only necessary to set the distance between the trigger mechanism and the inner surface of the gun body socket, so that when the charging gun and the locking mechanism are locked, the trigger mechanism can just close the normally open switch device; in other words, when the charging gun and the locking mechanism are not locked, the trigger mechanism cannot close the normally open switch device, thus forming a unique triggering condition, and when the triggering condition is met, the charging gun must have been locked and will not fall off again.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Figure 1 A DC charging pile gun socket with an indication function disclosed in an embodiment of the utility model is shown, including a gun body socket 1, a normally open switch device 2, a relay 3 and a gun hanging state indication module 4. The gun body socket 1 has an inner surface 5, and a switch slot is opened on the inner surface 5. The trigger mechanism of the normally open switch device 2 passes through the switch slot and is exposed on the inner surface 5. The relay 3 is electrically connected to the normally open switch device 2 and the gun hanging state indication module 4 respectively.

[0022] like Figure 2 As shown, when the charging gun is hung, the charging gun touches the trigger mechanism, so that the normally open switch device 2 is closed, triggering the relay 3, and the relay 3 controls the hanging gun state indication module 4 to work.

[0023] In a preferred embodiment, the gun-hanging state indication module 4 is an indicator light, which is arranged on the surface of the DC charging pile gun-hanging socket, and is electrically connected to the relay 3. When the normally open switch device 2 is closed, the relay 3 controls the indicator light to light up, prompting the user that the gun-hanging is completed.

[0024] In other embodiments, the gun hanging state indication module 4 may also be a voice prompt module, which is electrically connected to the relay 3. When the normally open switch device 2 is closed, the relay 3 controls the voice prompt module to trigger a voice broadcast to prompt the user that the gun hanging is completed.

[0025] The normally open switch device 2 may be, but is not limited to, a micro switch. Preferably, the switching stroke of the micro switch is 1.5 mm.

[0026] In order to form a secure gun hanging state, the utility model is also provided with a locking mechanism 6, which is arranged on the gun body socket 1, and the locking mechanism 6 is adapted to the setting position of the trigger mechanism, so that the triggering method is simpler and more reliable. The normally open switch device 2 is arranged in cooperation with the locking mechanism 6, and it is only necessary to set the distance between the trigger mechanism exposed to the inner surface 5 of the gun body socket 1, so that when the charging gun is locked with the locking mechanism 6, the trigger mechanism can just close the normally open switch device 2; in other words, when the charging gun is not locked with the locking mechanism 6, the trigger mechanism cannot close the normally open switch device 2, thereby forming a unique triggering condition, and when the triggering condition is achieved, the charging gun must have been locked and will not fall off again.
