The first embodiment is as follows:
referring to fig. 1, a locking rifle that charges that moves that new energy automobile is used, including rifle body 1 that charges, the hollow moulding cover 2 of rifle body 1 lateral wall fixedly connected with, hollow moulding cover 2 adopts soft plastic material to make, good plasticity effect has, air pocket 3 has been seted up to rifle body 1's lateral wall that charges, every sliding connection has plug 4 in the air pocket 3, air pocket 3 passes through pipe 5 and the inside intercommunication of hollow moulding cover 2, and plug 4 is on air pocket 3's inner wall through 6 elastic connection of conducting spring, install two first conducting blocks 9 on two relative inner walls of air pocket 3, be equipped with conducting rod 10 between two first conducting blocks 9, two 9 electric connection of first conducting block are in rifle body 1's power supply circuit that charges, and conducting spring 6 and first 9 electric connection of conducting block.
The driving device comprises second conductive blocks 8 arranged on two opposite inner walls of the air tank 3, a conductive rod 10 is connected in the air tank 3 in a sliding mode, the conductive rod 10 is elastically connected to the inner walls of the air tank 3 through a first memory alloy spring 11, the first memory alloy spring 11 is made of CuZnAl memory alloy wires in a winding mode, the conductive rod is in a shortening state at a lower temperature state and is in an extending state at a high temperature (80-95 ℃), an electromagnet 7 electrically connected with the second conductive blocks 8 is arranged in the air tank 3, a push plug 4 is made of iron, and the two second conductive blocks 8 are electrically connected in a power supply circuit of the charging gun body 1. The connection mode and the respective installation mode among the first conductive block 9, the second conductive block 8, the conductive spring 6 and the electromagnet 7 belong to the mature technology in the existing electrical field, and are not described in detail.
This device is in the use, and the overall dimension that will charge rifle body 1 makes lessly, and the rifle that both conveniently charges like this inserts the interface that charges of each model, still can save manufacturing cost simultaneously. In the initial state, the conductive rod 10 is between the two first conductive blocks 9, after the rechargeable gun is inserted into the interface and the charging circuit is switched on, the conductive spring 6 is electrified and contracted, referring to fig. 1, the push plug 4 can be pulled to move left, so that air is extruded into the hollow shaping sleeve 2 along the guide pipe 5, the hollow shaping sleeve 2 is expanded until the outer wall of the hollow shaping sleeve 2 is contacted with the inner wall of the interface, the appearance of the rechargeable gun is perfectly matched with the interface, the rechargeable gun is fully filled with the whole interface, and the interface of automobiles of various models can be matched in the way, and can not loosen and fall off in the charging process.
It is worth mentioning in addition, when the push plug 4 moves left, still can be with the air suction air pocket 3 in the bellows 14 in, make the bellows 14 shrink simultaneously and pulling slider 13 moves to the right, owing to make the rifle that charges "fill up" whole interface this moment, the interface is inside comparatively airtight, consequently can make certain negative pressure produce in the bar groove 12 when slider 13 moves to the right, thereby make the rifle that charges adsorbed in the interface, further improve the firm effect of rifle that charges when charging.
When the temperature rises due to abnormal charging, when the temperature rises to the stretching temperature of the first memory alloy spring 11, the first memory alloy spring 11 extends and pushes the conductive rod 10 to move to the left, at the moment, the conductive rod 10 moves between the two second conductive blocks 8, at the moment, the conductive spring 6 is powered off and extends and resets, the push plug 4 is pushed to move to the right and resets, air in the hollow shaping sleeve 2 is pumped back into the air groove 3, the hollow shaping sleeve 2 is shriveled immediately, meanwhile, the electromagnet 7 is powered on, the push plug 4 made of the attractable iron is attached to the attractable iron, the push plug 4 can continue to move to the right, air can be rapidly blown into the corrugated pipe 14, and the slide block 13 is rapidly pushed to pop out of the strip-shaped groove 12 and impact the inner wall of the charging interface, the charging gun is pushed in the direction to rapidly separate from the charging interface, and damage to an automobile and charging equipment due to overhigh temperature is.
Example two:
referring to fig. 2-3, different from the first embodiment, a through hole 41 is formed in a side wall of the plunger 4, the plunger 16 is hermetically and slidably connected in the through hole 41, the conductive spring 6 is fixedly connected to the side wall of the plunger 16, a pin hole 411 is formed in an inner wall of the through hole 41, a sliding groove 161 is formed in the side wall of the plunger 16, a pin rod 17 is slidably connected in the sliding groove 161, the pin rod 17 is elastically connected in the sliding groove 161 through a second memory alloy spring 18, the second memory alloy spring 18 is also made of a CuZnAl memory alloy wire, and is in an extended state at a low temperature and in a shortened state at a high temperature (65 ℃ -85 ℃). As shown in fig. 2, the push rod 16 is long, so that the through hole 41 can be always attached to the push rod 16 to obtain good airtightness, and the push plug 4 can be smoothly moved in the left-right direction.
In this embodiment, when the temperature is too high and rises to the expansion temperature of the second memory alloy spring 18, the second memory alloy spring 18 contracts and is pulled into the sliding groove 161 by the pin 17, so that the plunger 16 and the conductive spring 6 are separated from the plunger 4, and thus when the electromagnet 7 is powered on to attract the plunger 4 to move towards the plunger, the plunger 4 loses the limit of the conductive spring 6, the plunger 4 can move towards the electromagnet 7 more quickly, and the charging gun can be disengaged from the interface more quickly. After the plug is separated from the groove, the plug is inserted into the groove 12 by using a straight bar such as a screwdriver, the slider 13 is pushed to move right to blow air in the corrugated pipe 14 into the air groove, so that the plug 4 moves left to reset, and after the temperature is reduced, the second memory alloy spring 18 extends and pushes the pin rod 17 into the pin hole 411 again, so that the plug is convenient to use next time.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
