[0046] 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.

[0047] Example 1

[0048] See also Figure 1-Figure 5 The utility model provides the following technical solutions: a charging gun with an anti-falling structure, comprising a charging gun body 1, a charging head 2 fixed to the head of the charging gun body 1, and a handle 3 fixed to the charging gun body 1, an anti-falling mechanism 4 is also installed on the charging gun body 1, and the anti-falling mechanism 4 includes: a swing arm 41, a hook 4121, a second return spring 42, a lifting seat 43, an inner support clamp 44 and a linkage mechanism.

[0049] Further, by Figure 1 and Figure 2 As shown, the swing arm 41 is rotatably installed in the charging gun body 1, and is composed of a first connecting arm 411 and a second connecting arm 412 to form a retractable swing arm 41. The hook 4121 is fixed to the free end of the second connecting arm 412, and is used to be clamped on the car charging port. The second reset spring 42 is located between the swing arm 41 and the inner wall of the charging gun body 1. The lifting seat 43 is movably arranged in the charging gun body 1 and can move relative to the swing arm 41. The inner support clamp 44 is fixed on the lifting seat 43, and a hole is provided on the charging head 2. The inner support clamp 44 is located in the hole. The lifting seat 43 is connected to the first connecting arm 411 through a linkage mechanism, and when the first connecting arm 411 moves in a direction away from the second connecting arm 412, the lifting seat 43 moves in a direction close to the second connecting arm 412. In a safe situation The inner support clamp 44 is located in the hole of the charging head 2, and the charging head 2 can be normally inserted into the car charging port. At this time, the hook 4121 is clamped on the car charging port to fix the charging gun body 1. When the external force accidentally pulls the charging gun body 1, the first connecting arm 411 will move in the direction away from the second connecting arm 412. The second connecting arm 412 will not move because the hook 4121 is clamped on the car charging port, and the movement of the first connecting arm 411 causes the lifting seat 43 to move toward the second connecting arm 412 through the linkage mechanism. At this time, the inner support clamp 44 extends out of the hole of the charging head 2 and tightens the inner wall of the car charging port. The greater the force of pulling the charging gun body 1 outward, the greater the force of tightening the car charging port, thereby improving the stability and safety of the use of the charging gun body 1.

[0050] Preferably, by Figure 1-Figure 3As shown, in this embodiment, it also includes: a first connecting block 4111, a second connecting block 4122, a mounting rod 4112 and a first return spring 4114, the first connecting block 4111 is fixed to the end of the first connecting arm 411, the second connecting block 4122 is fixed to the end of the second connecting arm 412, the mounting rod 4112 is fixed to the first connecting block 4111 and passes through the second connecting block 4122, and a first limiting plate 4113 is fixed to the protruding end of the mounting rod 4112, the first return spring 4114 is sleeved on the mounting rod 4112 and is located between the second connecting block 4122 and the first limiting plate 4113, that is, in a safe situation, due to the presence of the first return spring 4114, the first connecting block 4111 and the second connecting block 4122 are in a state of mutual contact, the first connecting arm 411 is docked with the second connecting arm 412, and when the first connecting arm 411 moves in a direction away from the second connecting arm 412, the first return spring 4114 contracts.

[0051] Preferably, by Figure 1-Figure 3 As shown, in the present embodiment, there are two symmetrically distributed mounting rods 4112, and the two mounting rods 4112 are utilized to connect the first connecting block 4111 and the second connecting block 4122, which has higher stability and avoids relative rotation between the first connecting block 4111 and the second connecting block 4122. Theoretically, the more mounting rods 4112 are provided, the higher the stability. Considering the cost issue, two mounting rods 4112 can meet the needs and the cost is low.

[0052] It is worth noting that the mounting rod 4112 shown in the present embodiment is cylindrical, but is not limited to the cylindrical shape, and the use of mounting rods 4112 of other shapes can also meet the needs, such as square, polygonal, etc.

[0053] Optionally, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the linkage mechanism includes: a linkage plate 4115, a boss 4116 and a connecting shaft 4117.

The third reset spring 8 is sleeved on the mounting column 6 and is located between the second limiting plate 7 and the fixed block 433. In the initial state, the lifting seat 43 is in a lower position through the elastic force of the third reset spring 8. At this time, the inner support clamp 44 is located in the hole of the charging head 2. The mounting column 6 is used to install and guide the lifting seat 43 to ensure the stability of the lifting seat 43 and ensure that the lifting seat 43 moves in a straight line. When the lifting seat 43 moves up, the third reset spring 8 contracts.

[0056] Preferably, by Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, it also includes: a limit ring 9, which is fixed on the mounting column 6 and located below the fixed block 433. When the fixed block 433 contacts the limit ring 9, the connecting shaft 4117 is located at the end of the avoidance opening 432. The limit ring 9 is used to limit the lifting seat 43 to ensure that in the initial state, the connecting shaft 4117 has an upward space instead of directly against the inner wall of the avoidance opening 432, so as to avoid affecting the unlocking and removal of the charging gun body 1.

[0057] Preferably, by Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in this embodiment, two groups of symmetrically distributed fixing blocks 433 are fixed on the outer wall of the lifting seat 43, and there are two fixing blocks 433 in the same group distributed at intervals, which are used to install and guide the lifting seat 43, ensure the stability of the lifting seat 43, and ensure that the lifting seat 43 moves in a straight line.

[0058] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the cross-section of the lifting seat 43 is "n"-shaped, the boss 4116 is located on the inner side of the lifting seat 43, and guide grooves 431 and avoidance openings 432 are opened on the two vertical parts of the lifting seat 43.

[0063] When the external force accidentally pulls the charging gun body 1, the first connecting arm 411 will move in the direction away from the second connecting arm 412. The second connecting arm 412 will not move because the hook 4121 is clamped on the car charging port, and the movement of the first connecting arm 411 will drive the linkage plate 4115 to move. The linkage plate 4115 uses the boss 4116 to drive the connecting shaft 4117 to move in the guide slot 431. The connecting shaft 4117 moves along the inclined surface of the guide slot 431 and lifts the lifting seat 43, so that the inner support clamp 44 extends out of the hole of the charging head 2 and tightens the inner wall of the car charging port. The greater the force of pulling the charging gun body 1 outward, the greater the force of tightening the car charging port, thereby improving the stability and safety of the use of the charging gun body 1.

[0064] In the initial state, the lifting seat 43 is in a lower position due to the elastic force of the third return spring 8, and the inner support clamp 44 is located in the hole of the charging head 2;

[0065] When the charging gun body 1 needs to be pulled out, the tail end of the swing arm 41 is pressed down to flip the swing arm 41. At this time, the second return spring 42 contracts, the connecting shaft 4117 enters the avoidance opening 432, the lifting seat 43 is stationary, and the hook 4121 is separated from the car charging port, and the charging gun body 1 can be easily pulled out.

[0066] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
