Description

Technical Field

[0001] This utility model relates to the field of charging head protection technology, and in particular to a protective device for a charging head of a new energy vehicle. Background Technology

[0002] A charging pile is a power replenishment device that provides electricity to electric vehicles. Its function is similar to that of a gas pump in a gas station. It can be fixed on the ground or wall and can charge various models of electric vehicles by adjusting the voltage and current. Its charging end can be inserted into the charging port of the new energy vehicle to charge it.

[0003] Existing charging terminals typically have a simple cover plate at the end for protection. However, in actual use, the cover plate is merely clipped onto the outer surface of the charging terminal and lacks a locking mechanism. This makes it prone to wear and tear during prolonged handling, and the cover plate may easily fall off. Therefore, we propose a protective device for new energy vehicle charging heads.

[0027] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0028] Example:

[0029] like Figures 1-5 As shown, a protective device for a new energy vehicle charging head includes a charging head 1, a connection socket 2 fixedly provided at the end of the charging head 1, a connection adjustment mechanism 3 fixedly connected to the top of the charging head 1, and a connection protection mechanism 4 movably connected to the outer side of the output end of the connection adjustment mechanism 3.

[0030] The working principle of the above technical solution is as follows:

[0031] During use, the connection adjustment mechanism 3 can be adjusted. After adjustment, the internal components of the connection protection mechanism 4 can be adjusted, and then the connection protection mechanism 4 can be deflected as a whole, so that the connection protection mechanism 4 moves to the end of the connection socket 2. Then the connection adjustment mechanism 3 can be adjusted again, so that the connection protection mechanism 4 can be inserted into the inside of the connection socket 2 and cover the outside of the end of the connection socket 2, providing stable protection for the connection socket 2. The operation is convenient and quick.

[0032] In another embodiment, such as Figure 4 As shown, the connecting adjustment mechanism 3 includes a fixed connecting block 31. A fixed guide rod 32 is symmetrically provided on the bottom of one side of the fixed connecting block 31. A threaded collar 33 is fixedly connected to the other side of the fixed connecting block 31. A threaded mounting rod 34 is movably connected to the inner side of the threaded collar 33 and the fixed connecting block 31. The outer side of the threaded mounting rod 34 is connected to the inner side of the threaded collar 33 by threads. The threaded mounting rod 34 and the fixed connecting block 31 slide against each other. A rotating end block 35 is fixedly connected to one end of the threaded mounting rod 34, and a connecting end block 36 is fixedly connected to the other end of the threaded mounting rod 34.

[0033] The rotating end block 35 is easy to rotate, which drives the threaded mounting rod 34 and the connecting end block 36 to rotate, so that the threaded mounting rod 34 can move inside the threaded collar 33, thereby driving the connecting end block 36 to move, and thus driving the connecting protection mechanism 4 to move, making the operation convenient and quick.

[0034] In another embodiment, such as Figure 4 As shown, the connection protection mechanism 4 includes a first connecting sleeve block 41 that is movably sleeved on the outer side of the surface of the connecting end block 36. A connecting mounting block 42 is fixedly connected to one side of the first connecting sleeve block 41. A connecting base plate 43 is fixedly connected to the bottom of one side of the connecting mounting block 42. A connecting mounting arm 44 is fixedly connected to the other side of the connecting mounting block 42. A fixing slot 45 is provided at the top of the connecting mounting arm 44. A movable connecting arm 46 is movably connected to the other end of the connecting mounting arm 44 through a connecting shaft. A connecting mounting plate 47 is fixedly connected to the bottom of the movable connecting arm 46. A connecting insert block 48 is fixedly connected to one side of the connecting mounting plate 47. A connecting positioning component 49 is fixedly connected to the other side of the connecting mounting plate 47.

[0035] The connecting positioning component 49 is adjusted to disengage it from the fixed slot 45. Then, the movable connecting arm 46, connecting mounting plate 47, connecting plug 48, and connecting positioning component 49 are deflected so that the connecting mounting plate 47 and connecting plug 48 are at the end of the connecting socket 2. Next, the connecting adjustment mechanism 3 is adjusted so that the connecting protection mechanism 4 moves as a whole, allowing the connecting plug 48 to be inserted into the inside of the connecting socket 2, and the connecting mounting plate 47 to be at the end of the connecting socket 2, thereby providing stable protection for the connecting socket 2 and making the operation convenient.

[0036] In another embodiment, such as Figure 4 As shown, the outer surface of the connecting plug 48 is in contact with the inner surface of the connecting socket 2.

[0037] The connector 48 can be stably inserted into the inside of the connector 2, providing protection for the connector 2 and making operation convenient.

[0038] In another embodiment, such as Figure 4 As shown, the outer bottom end of the connecting mounting block 42 and the outer edge of the connecting base plate 43 slide against the inner side of the fixed guide rod 32.

[0039] The bottom of the connecting mounting block 42 and the connecting base plate 43 can move stably inside the fixed guide rod 32, making operation convenient.

[0040] In another embodiment, such as Figure 5 As shown, the connecting positioning assembly 49 includes a second connecting sleeve block 491. A movable positioning rod 492 is movably connected inside the second connecting sleeve block 491. A force-bearing sleeve plate 493 is fixedly sleeved on the outer surface of the movable positioning rod 492. A force-bearing spring 494 is fixedly connected between the bottom of the force-bearing sleeve plate 493 and the inner bottom end of the second connecting sleeve block 491. A connecting pull block 495 is fixedly connected to the bottom end of the movable positioning rod 492.

[0041] The connecting block 495 is easy to pull, which moves the movable positioning rod 492 and the force-bearing sleeve 493, compresses the force-bearing spring 494, and causes the end of the movable positioning rod 492 to retract into the second connecting sleeve 491, thereby making stable adjustment and easy to use.

[0042] In another embodiment, such as Figure 5 As shown, the outer side of the end surface of the movable positioning rod 492 slides and fits against the inner side of the fixed slot 45.

[0043] The end of the movable positioning rod 492 can be stably inserted into the inside of the fixed slot 45, making operation convenient and quick.

[0044] The working principle of this utility model is as follows: During use, after the charging head 1 and the connecting socket 2 are used, the rotating end block 35 is rotated, which drives the threaded mounting rod 34 and the connecting end block 36 to rotate. This allows the threaded mounting rod 34 to move inside the threaded collar 33, thereby driving the connecting end block 36 to move, which in turn drives the connecting protection mechanism 4 to move. Then, the connecting pull block 495 is pulled, which drives the movable positioning rod 492 and the force-bearing sleeve 493 to move, compressing the force spring 494. This causes the end of the movable positioning rod 492 to retract into the second connecting sleeve 491, thus moving the movable positioning rod 492 into the second connecting sleeve 491. The end of 92 can detach from the inside of the fixed slot 45, and the connection restriction is no longer applied. Then, the movable connecting arm 46 is deflected, which drives the connecting mounting plate 47, the connecting plug 48 and the connecting positioning component 49 to deflect, so that the connecting mounting plate 47 and the connecting plug 48 move to the outside of the end of the connecting socket 2. Then, the rotating end block 35 is rotated in the opposite direction, so that the connecting adjustment mechanism 3 and the connecting protection mechanism 4 move and reset as a whole, so that the connecting plug 48 can be inserted into the inside of the connecting socket 2. At the same time, the connecting mounting plate 47 and the end of the connecting socket 2 fit together, thereby providing stable protection for the connecting socket 2. The overall structure is simple and the operation is convenient and quick.

[0045] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
