DETAILED DESCRIPTION

[0034] 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 part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0035] It should be noted that, unless otherwise defined, the technical terms or scientific terms used herein should have the common meanings understood by persons having ordinary skills in the field to which the present disclosure belongs.

[0036] In the description of the present invention, some directional terms are based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention. In the embodiments of the present invention, such as "upper", "lower", "side", etc., they are generally used as Figure 1 The relative relationship of the orientation shown in the figure is used as the basis, and these orientation terms are used only to more clearly describe the relationship between structures, not to describe absolute orientation. When the product is placed in different postures, the orientation may change, for example, "up" and "down" may be interchangeable.

[0037] In order to make the technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] In the related art, the gun head of the charging gun includes a plug connector for plugging into the charging interface, and a gun body end. In order to ensure the sealing inside the gun body, an end plate is usually provided to separate the plug connector and the gun body end. In order to protect the gun body end, an end cover shell is usually sleeved on the gun body end, and the end cover shell is the last component to be installed when assembling the charging gun, and is directly installed on the gun body end from the plug connector. Due to the existence of the end plate, a protrusion cannot be provided inside the end cover shell, otherwise the protrusion will interfere with the end plate and cannot be installed. Therefore, the end cover shell and the gun body end are usually connected by gluing to avoid radial rotation between the end cover shell and the gun body end. However, many charging guns are placed in outdoor environments, and are prone to degumming after long-term use, which allows radial rotation between the end cover shell and the gun body end, affecting the safety of the charging gun.

[0039] In order to solve the problems existing in the related art, an embodiment of the utility model provides a charging gun, which can avoid radial rotation between the end cover shell and the end of the gun body without gluing, thereby ensuring the safe use of the charging gun.

[0040] Figure 1 A schematic diagram of the structure of an exemplary charging gun provided in an embodiment of the utility model, wherein the left side diagram is a schematic diagram of the overall structure of the charging gun, and the right side diagram is a schematic diagram of the disassembled structure of the charging gun; Figure 2 A schematic diagram of a partially disassembled structure of an exemplary charging gun provided in an embodiment of the utility model; Figure 3 This is a schematic diagram of a partial structure of an exemplary charging gun provided by an embodiment of the utility model, wherein the left side figure is a top view of the charging gun, and the right side figure is a cross-sectional view of the left side figure taken along line AA. Figure 1 , Figure 2 and Figure 3 The charging gun includes a gun head 1 and an end cover shell 2, wherein the gun head 1 includes a gun body end 11, a plug connector 12 and an end plate 13, the end plate 13 is arranged between the plug connector 12 and the gun body end 11, and is respectively connected to the plug connector 12 and the gun body end 11; the end cover shell 2 is hollow ring-shaped and is sleeved on the gun body end 11 to protect and decorate the gun body end 11.

[0041] See also Figure 3 The end 11 of the gun body has a locking member 14, and the end plate 13 has an opening 131. One end of the locking member 14 extends from the opening 131, so as to be locked with the card slot in the power receiving device when the charging gun is inserted into the power receiving device, so as to realize the connection between the charging gun and the power receiving device; see Figure 2 The end cover housing 2 has a protrusion 200 ( Figure 2 A limiting member 21 is disposed on the inner wall of the protrusion 200, and the limiting member 21 is located beside the locking member 14 and abuts against the locking member 14 to achieve radial limiting of the end cover shell 2 to prevent it from radial rotation.

[0042] The charging gun provided by the utility model provides a limit piece 21 on the inner wall of the protrusion 200 on the side of the end cover shell 2 away from the plug connector 12, and the limit piece 21 is clamped on the side of the locking piece 14, so that the end cover shell 2 cannot generate radial rotation between the gun body end 11 under the limiting action of the limit piece 21, thereby ensuring the safe use of the charging gun without gluing.

[0043] The structure of the charging gun provided in the embodiment of the utility model is described in detail below:

[0044] See also Figure 4 ,in Figure 4A schematic diagram of the structure of an exemplary end cover shell of a charging gun provided for an embodiment of the utility model. In the embodiment of the utility model, the limit member 21 may include a first limit member 2101 and a second limit member 2102. The first limit member 2101 and the second limit member 2102 are relatively located on both sides of the locking member 14, so that the locking member 14 can be clamped between the first limit member 2101 and the second limit member 2102. Since the first limit member 2101 and the second limit member 2102 are both in contact with the locking member 14, even when a radial force is applied to the end cover shell 2 from the outside, the first limit member 2101 and the second limit member 2102 are blocked by the locking member 14, and neither the first limit member 2101 nor the second limit member 2102 can jump over the locking member 14, so that the position between the end cover shell 2 and the locking member 14 remains relatively stable, that is, no radial rotation can occur between the end cover shell 2 and the gun body end 11.

[0045] See also Figure 5 and Figure 6 ,in Figure 5 A schematic diagram of the structure of an end cover housing of an exemplary charging gun provided in an embodiment of the utility model at another angle; Figure 6 A schematic diagram of the structure of an exemplary end cap housing in a charging gun provided in an embodiment of the utility model at another angle. The main body of the end cap housing 2 is a hollow cylinder, the protrusion 200 is located on one side of the hollow cylinder, and the limiter 21 is arranged on the inner wall of the protrusion 200. Due to the presence of the protrusion 200, the end cap housing 2 can rotate relative to the gun body end 11 when it is sleeved on the gun body end 11, so as to facilitate the first limiter 2101 and the second limiter 2102 to pass from the side where the plug connector 12 is located through the opening 131 to the side where the gun body end 11 is located.

[0046] In the embodiment of the utility model, when the end cover housing 2 is installed on the end 11 of the gun body, the protrusion 200 can be firstly sleeved on the end 11 of the gun body, the first stopper 2101 can be inserted from the opening 131, and then the end cover housing 2 can be rotated to insert the second stopper 2102 from the opening 131, and then the end cover housing 2 can be rotated to sleeve the end cover housing 2 on the end 11 of the gun body. In the above steps, the order of the first stopper 2101 and the second stopper 2102 being inserted from the opening 131 can be the first stopper 2101 first and then the second stopper 2102 as described above, or the second stopper 2102 first and then the first stopper 2102, which is not specifically limited here.

[0047] For the specific location of the stopper 21 on the end cover housing 2, see Figure 4 The end cover shell 2 includes a flat wall portion 201 and an arc wall portion 202 . The two sides of the flat wall portion 201 are respectively connected to the two sides of the arc wall portion 202 . The limiting member 21 is arranged at the connection between the flat wall portion 201 and the arc wall portion 202 .

[0048] Exemplarily, the first limiting member 2101 and the second limiting member 2102 are respectively disposed at two connection points between the flat wall portion 201 and the arc wall portion 202 .

[0049] Continue to see Figure 4 In the embodiment of the utility model, the connection between the flat wall portion 201 and the arc wall portion 202 may have a transition portion, and the transition portion may be arc-shaped, so that the connection between the flat wall portion 201 and the arc wall portion 202 is more natural and smooth.

[0050] In some embodiments, see Figure 3 and Figure 4 The limiting member 21 protrudes inward from the inner wall of the end cover shell 2 , so that the limiting member 21 forms a convex rib structure on the inner wall of the end cover shell 2 .

[0051] It is understandable that the convex rib structure can be a solid rib structure or a hollow rib structure. Figure 3 or Figure 4 The convex rib structure can be a hollow rib structure, which can reduce the preparation materials while meeting the strength requirements.

[0052] For example, see Figure 4 The first limiting member 2101 and the second limiting member 2102 are two symmetrically arranged hollow rib structures.

[0053] In some embodiments, see Figure 3 and Figure 4 The limiting member 21 has a first abutting surface 211 , and the locking member 14 has a second abutting surface 140 . The first abutting surface 211 is parallel to and in contact with the second abutting surface 140 .

[0054] In this way, when the end cover housing 2 is installed on the gun body end 11 , the limiting member 21 can cooperate with the locking member 14 to achieve positioning guidance, so that the limiting member 21 can slide along the locking member 14 to a predetermined installation position.

[0055] Continue to see Figure 3 and Figure 4 In addition to the first abutting surface 211, in the embodiment of the utility model, the limiting member 21 also has a connecting surface 212, and the connecting surface 212 is connected with the first abutting surface 211 to form an L-shaped cross-section, so that the limiting member 21 forms an L-shaped rib structure. The L-shaped rib structure not only has high structural strength, but also is easy to prepare because the corresponding preparation mold is simple.

[0056] It should be noted that, in other embodiments, the shape of the limiting member 21 may also be a rectangular rib structure, an irregular rib structure, etc., which is not specifically limited here.

[0057] In some embodiments, see Figure 7 ,in Figure 7 Another schematic diagram of a partial disassembled structure of an exemplary charging gun provided in an embodiment of the utility model. The locking member 14 includes a guide plate 141, a hook 142 and a pin 143. The guide plate 141 is located beside the hook 142. The hook 142 and the guide plate 141 are connected by the pin 143. The stopper 21 abuts against the end of the pin 143, so that the stopper 21 can fix the pin 143 after being installed in place to prevent the pin 143 from sliding out.

[0058] Compared with the related art that requires a special fixing component for the pin shaft 143, the embodiment of the utility model uses the limiting member 21 on the end cover housing 2 to limit the pin shaft 143, which can effectively reduce the number of parts, not only helps to reduce the preparation cost, but also improves the space utilization. Therefore, the limiting member 21 provided in the embodiment of the utility model can not only prevent the radial rotation of the end cover housing 2, but also achieve the fixed limit of the pin shaft 143, and can also achieve positioning guidance during the installation process.

[0059] In the embodiment of the utility model, when the first limiting member 2101 and the second limiting member 2102 reach the assembly position, they are just located on both sides of the pin shaft 143 , thereby achieving the limiting of the pin shaft 143 .

[0060] In the embodiment of the present utility model, see Figure 7 In order to cooperate with the stopper 21, the guide plate 141 may include two guide plates located on both sides of the hook 142, one of which cooperates with the first stopper 2101, and the other cooperates with the second stopper 2102. It can be understood that the second abutting surface 140 is the surface of the guide plate 141 away from the hook 142.

[0061] Combination Figure 3 and Figure 7 In the embodiment of the utility model, the pin shaft 143 is a cylindrical shaft structure, the guide plate 141 has a fixing hole 1411, and the hook 142 has a hook hole 1421. When the locking member 14 is installed, the pin shaft 143 can pass through the fixing hole 1411 of one guide plate 141, the hook hole 1421 of the hook 142 and the fixing hole 1411 of another guide plate 141 in sequence.

[0062] In some embodiments, see Figure 4 and Figure 7 When the end cover housing 2 and the gun body end 11 are installed and fixed, in addition to the limiting between the limiting member 21 and the locking member 14, the two can also be further engaged by the matching mode of the groove body and the protrusion. In the embodiment of the utility model, there are two possible implementation modes:

[0063] In one possible implementation, the inner wall of the end cover shell 2 has a groove (not shown in the figure), and the outer wall of the gun body end 11 has a protrusion (not shown in the figure) that matches the groove, so that when the end cover shell 2 is installed to the gun body end 11, the protrusion of the gun body end 11 can correspond to enter the groove of the end cover shell 2, realizing a snap-fit ​​fit between the protrusion and the groove, thereby ensuring the firmness of the connection between the end cover shell 2 and the gun body end 11.

[0064] In another possible implementation, see Figure 7 The outer wall of the gun body end 11 has a groove 112, see Figure 4 The inner wall of the end cover shell 2 has a protrusion 22 that cooperates with the groove body 111, so that when the end cover shell 2 is installed to the gun body end 11, the protrusion on the inner wall of the end cover shell 2 can correspondingly enter the groove body 111 of the gun body end 11, realizing the snap-fitting fit between the protrusion and the groove body, ensuring the firmness of the connection between the end cover shell 2 and the gun body end 11.

[0065] Further, see Figure 4 The protrusion 22 has at least one protruding hook 221 on the side facing the gun body 12, and the length of the protruding hook 221 is slightly greater than the maximum height of the protrusion 22; correspondingly, see Figure 7 The groove 112 has a limiting portion 1111 on the side facing the gun body 12, and the depth of the limiting portion 1111 is greater than the maximum depth of the groove 112. In this way, when the protrusion of the end cover housing 2 moves to the assembly position along the groove of the gun body end 11, the convex hook 221 can enter the limiting portion 1111 and abut against the side wall of the limiting portion 1111 away from the gun body 12, further ensuring the fixed connection between the end cover housing 2 and the gun body end 11.

[0066] For example, see Figure 4 The number of the convex hooks 221 can be three, and they are arranged at intervals on the side of the protrusion 22 facing the gun body 12.

[0067] In some embodiments, the inner wall surface of the portion of the end cover shell 2 surrounding the limiting member 21 is set to be a frosted surface, so that the end cover shell 2 is easier to demould during preparation, which is convenient for preparation.

[0068] The embodiment of the utility model further provides a charging device, which includes the charging gun involved in the above embodiment.

[0069] Based on the charging gun involved in the above embodiment, the safe use of the charging device can be ensured.

[0070] Furthermore, the charging device may be a charging pile.
