In order to make the technical scheme and advantages of the present utility model more apparent, embodiments of the present utility model will be described in further detail with reference to the accompanying drawings.

In one aspect, the present utility model provides a charging gun protection mechanism 001, as shown in fig. 1, the charging gun protection mechanism 001 includes: a protective cover 1, a tail cover 2 and a wire protective sleeve 3; wherein, the wire sheath 3 includes: the tail cover 2 is sleeved on the wire-protecting small-diameter part 32, and one end of the tail cover 2 is abutted against one end of the wire-protecting large-diameter part 31. The protective cover 1 includes: the protective cover 11 and the rope 12, one end of the rope 12 is connected with the protective cover 11, the other end of the rope 12 is provided with a connecting part 13, and the connecting part 13 can be clamped between the tail cover 2 and the wire-protecting large-diameter part 31.

The charging gun protection mechanism 001 provided by the embodiment of the utility model can be applied to a charging gun, the protection cover 1 is hung on the charging gun through the rope body 12, and the protection cover 11 is used for covering the plug part 100 of the charging gun to carry out protection measures such as water proofing and dust proofing. The other end of the rope body 12 of the protective cover 1 is provided with the connecting part 13, the connecting part 13 is clamped between the tail cover 2 and the wire-protecting large-diameter part 31 of the wire-protecting sleeve 3, and the rope body 12 is clamped and fixed by matching the tail cover 2 and the wire-protecting sleeve 3, so that the protective cover 1 is stably installed. Like this, when rifle protection machanism 001 is applied to the rifle that charges, make the connection position of rope body 12 hide in its inside casing 400 that charges the rifle, not only can reduce the risk that the connection position of rope body 12 was damaged, but also can guarantee casing 400 integrality, leakproofness and the aesthetic property of charging the rifle, make the inside IP67 standard grade that reaches of casing 400.

In the embodiment of the present utility model, the outer diameter of the wire-protecting large-diameter portion 31 is larger than the outer diameter of the wire-protecting small-diameter portion 32, so that a step surface is formed between the two, wherein the step surface is the end surface of the wire-protecting large-diameter portion 31, which is close to the wire-protecting small neck portion.

The string body 12 of the protective cover 1 may be interposed between the end surface of the tail cover 2 and the end surface of the wire-protecting large-diameter portion 31 in various manners, and will be described as an example.

In some implementations (1), as shown in fig. 2 and fig. 3, the connecting portion 13 is in a convex shape, the tail cover 2 is provided with a containing groove 20, and the connecting portion 13 is adapted to be contained in the containing groove 20.

The connecting portion 13 is designed into a convex shape, so that the connecting portion 13 is embedded into the accommodating groove 20 on the tail cover 2, and the convex connecting portion 13 has small volume and high strength (compared with a plate-shaped structure), so that the stable assembly effect can be achieved on the premise of simplifying the structure of the charging gun protection mechanism 001. In addition, based on this implementation, the connection portion 13 is designed not to contact the cable 300, and also to avoid undesired displacement of the cable 300 due to pulling of the rope body 12.

Based on this implementation (1), as shown in fig. 3, the connection portion 13 includes a first connection surface 131 and a second connection surface 132; the first connecting surface 131 is sandwiched between the tail cap 2 and the wire-protecting large-diameter portion 31; the second connection surface 132 is connected to the rope 12.

In this example, the first connection surface 131 and the second connection surface 132 cooperate to form an L-shaped structure, which each performs its role, not only to enhance the assembly stability of the connection portion 13, but also to enhance the service life of the connection portion 13.

In the case where the connection portion 13 includes both the first connection face 131 and the second connection face 132, for example, the area of the first connection face 131 is 10% -40% of the end face area of the tail cap 2. The area of the second connecting surface 132 is 10% -40% of the area of the side wall of the tail cap 2, including but not limited to 10%, 15%, 20%, 25%, 30%, 35%, etc. The first connection surface 131 and the second connection surface 132 can be designed to be small in size, and the stable assembly effect can be achieved on the premise of simplifying the structure of the charging gun protection mechanism 001.

Based on this implementation (1), in some examples, the first connection face 131 is level with the corresponding end face of the tail cap 2; the second connecting surface 132 is arc-shaped, and the second connecting surface 132 is smoothly connected with the corresponding side wall of the tail cover 2 to form a circular outer contour in a matching way.

By accommodating the connection portion 13 in the accommodation groove 20 provided on the tail cap 2, the first connection face 131 is made flush with the corresponding end face of the tail cap 2, so as to enhance the clamping strength of the first connection face 131 clamped by the tail cap 2 and the wire-protecting large-diameter portion 31.

Through making second connection face 132 and the lateral wall smooth connection of tail-hood 2, like this, when charging gun protection machanism 001 wholly assembles to the casing 400 inside of charging gun, the surface of second connection face 132 and the lateral wall of tail-hood 2 all can closely abut against with the inner wall of casing 400 to ensure the airtight of casing 400 inside, ensure that casing 400 inside reaches IP67 standard grade.

Based on this implementation (1), in some examples, as shown in fig. 3, the connection portion 13 has a first positioning structure 141 thereon; at least one of the end face of the tail cap 2 and the end face of the wire-protecting large-diameter portion 31 has a second positioning structure 142; the first positioning structure 141 and the second positioning structure 142 are positioned with each other.

The second positioning structure 142 may be provided only in the accommodating groove 20 of the tail cap 2, only on the end surface of the wire-protecting large-diameter portion 31, or both in the accommodating groove 20 of the tail cap 2 and on the end surface of the wire-protecting large-diameter portion 31.

The first connecting surface 131 and the tail cover 2 and/or the second positioning structure 142 arranged on the wire-protecting large-diameter part 31 are mutually positioned through the first positioning structure 141 so as to promote stable installation of the first connecting surface 131 therein, effectively prevent the connecting part 13 from generating unexpected displacement between the tail cover 2 and the wire-protecting large-diameter part 31, and simultaneously facilitate improvement of installation efficiency.

One of the first positioning structure 141 and the second positioning structure 142 is a positioning hole, the other is a positioning column, for example, fig. 3 illustrates that the first positioning structure 141 is a positioning hole and the positioning hole penetrates through the first connecting surface 131, and the second positioning structure 142 is a positioning column and is disposed inside the accommodating groove 20 of the tail cover 2, so that on the basis of ensuring stable installation of the first connecting surface 131, the structure of the charging gun protection mechanism 001 is further facilitated to be simplified.

In some implementations (2), the connection portion 13 is a ring-shaped plate body; the annular plate body is fitted over the outer portion of the wire-protecting small-diameter portion 32, and is sandwiched between the tail cap 2 and the wire-protecting large-diameter portion 31 (not shown).

The connecting part 13 is an annular plate body, the small diameter part 32 of the wire protection sleeve 3 is sleeved in the inner hole in the middle of the connecting part, positioning is achieved, and the annular plate body is clamped between the tail cover 2 and the large diameter part 31 of the wire protection, so that stable assembly of the connecting part 13 is achieved. The implementation mode has the advantages of simple structure, easy assembly and the like.

As shown in fig. 4, the wire protecting sleeve 3 is protected by sleeving the wire protecting large diameter part 31 and the wire protecting small diameter part 32 on the outer part of the cable 300, wherein the outer wall of the wire protecting large diameter part 31 is provided with a first convex rib 331 protruding outwards along the radial direction; the inner wall of at least one of the guard wire large diameter portion 31 and the guard wire small diameter portion 32 has second ribs 332 protruding radially inward.

The second bead 332 may be provided only in the wire-protecting large-diameter portion 31, only in the wire-protecting small-diameter portion 32, or both of the wire-protecting large-diameter portion 31 and the wire-protecting small-diameter portion 32.

The first ribs 331 are used for abutting against the inner wall of the housing 400 of the charging gun, so that a gap between the wire protecting sleeve 3 and the housing 400 of the charging gun is sealed. The second ribs 332 are used to abut against the outer wall of the cable 300, thereby sealing the gap between the wire sheath 3 and the cable 300.

The first ribs 331 and the second ribs 332 may be in the form of bumps, convex lines, or the like, for example, the first ribs 331 may be in a spiral ring shape, or may be in a plurality of annular rings arranged at intervals, and the second ribs 332 may be in a spiral ring shape, or may be in a plurality of annular rings arranged at intervals, so as to achieve a more excellent sealing effect.

As can be seen from the above, the charging gun protection mechanism 001 according to the embodiment of the utility model can reliably limit and insert and fix the protection cover 1 into the housing 400. This not only achieves the reliable limit embedding fixation of the protective cover 1 inside the housing 400, but also achieves the highly sealing characteristic of the housing 400 of the charging gun so that the tail end thereof meets the design waterproof requirement of the IP 67.

In addition, the wire protecting sleeve 3 not only plays a role in protecting the cable from bending during use, but also plays a role in sealing the tail end of the shell 400. Because the wire protecting sleeve 3 is soft rubber, the first convex rib 331 and the second convex rib 332 on the wire protecting sleeve are respectively and radially extruded between the shell 400 and the cable 300, so that the sealing instability of other forms of axial sealing caused by assembly errors is avoided, the protection effect on the cable is achieved, and the sealing effect on the tail end of the shell 400 is also achieved.

In another aspect, an embodiment of the present utility model further provides a charging gun, as shown in fig. 5, where the charging gun includes: plug section 100, gun tail 200, cable 300, and housing 400, housing 400 connects and at least partially encloses plug section 100 and gun tail 200. One end of the cable 300 is connected to the plug portion 100, and the other end of the cable 300 penetrates the gun tail 200 to the outside of the housing 400. As can be further seen in conjunction with fig. 4, the gun tail 200 includes: the charging gun protection mechanism 001 and the wire clamp mechanism 002, the charging gun protection mechanism 001 is as described in any one of the above, and the protection cover 1 can be covered on the plug portion 100 by the protection cover body 11.

The housing 400 is covered outside the charging gun protection mechanism 001, so that only the small diameter portion 32 of the wire sheath 3 partially protrudes outside the housing 400.

The charging gun provided by the embodiment of the utility model has all the advantages of the charging gun protection mechanism 001, so that the shell 400 has excellent waterproof and dustproof functions.

It can be appreciated that the inner cavity profile of the protective cover 11 is adapted to the outer profile of the plug portion 100, so that the protective cover 11 can be stably fixed to the outside of the plug portion 100 based on friction force, and can be separated from the plug portion 100 by means of external force.

In some implementations, as shown in fig. 6, the tail end of the housing 400 has a avoidance groove 401, and the rope 12 of the protection cover 1 penetrates to the outside of the housing 400 through the avoidance groove 401.

By providing the escape groove 401 at the rear end of the housing 400 to allow the rope 12 of the protective cover 1 to pass therethrough, smooth assembly of the rope 12 is achieved.

In some examples, one end of the relief groove 401 extends to an end face of the trailing end of the housing 400, thereby forming an opening to allow the rope 12 to enter the relief groove 401 therethrough.

In some implementations, as shown in fig. 4, the outer wall of the wire-protecting large-diameter portion 31 has a first rib 331 protruding radially outwards, and the first rib 331 is used to abut against a corresponding position on the inner wall of the housing 400.

The first ribs 331 are abutted against the inner wall of the housing 400 of the charging gun, so that a gap between the wire protecting sleeve 3 and the housing 400 of the charging gun is sealed, and an excellent sealing effect is achieved.

In some implementations, as shown in fig. 4, the inner wall of the guard wire large diameter portion 31 has second ribs 332 that protrude radially inward. The second ribs 332 are used to abut against the outer wall of the cable 300, thereby sealing the gap between the wire sheath 3 and the cable 300.

Any of the charging guns provided by the embodiment of the utility model has the following assembly process:

the tail cap 2, the wire sheath 3 and the wire clamping mechanism 002 are sequentially sleeved outside the cable 300, so that the cable 300 axially penetrates the housing 400. The front end of the housing 400 assembles the plug portion 100 such that the plug portion 100 is connected to the front end of the housing 400.

Gun tail 200 is assembled at the rear end of housing 400, which includes: the wire clamping mechanism 002 is fixedly connected to the housing 400 at the corresponding position by means of screws, thereby achieving the fixation of the cable 300. The wire-protecting large-diameter portion 31 of the wire-protecting cover 3 is pushed to the wire clamping mechanism 002, then the rope body 12 of the protecting cover 1 is combined to the tail cover 2 through the connecting portion 13 (for example, preliminary positioning of the tail cover 2 and the wire-protecting large-diameter portion 31 of the wire-protecting cover 3 is achieved through the first positioning structure 141 and the second positioning structure 142), the tail cover 2 is pushed to be abutted against the wire-protecting large-diameter portion 31 of the wire-protecting cover 3, and therefore the connecting portion 13 of the protecting cover 1 is clamped to the wire-protecting large-diameter portion 31 of the tail cover 2 and the wire-protecting cover 3. Finally, the tail cap 2 is fixedly connected to the corresponding position of the housing 400 by means of screws, so that the charging gun can be assembled.
