[0028] Obviously, the embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0029] In order to solve the problem in the prior art that a charging gun is easily infiltrated with water, resulting in failure of the electronic lock, the utility model provides a charging gun.

[0030] like Figures 1 to 4As shown, the charging gun includes a gun body 10, a partition 20 and an electronic lock 30. The gun body 10 has a hollow cavity, and the partition 20 is arranged on the gun body 10 and divides the hollow cavity into an inner cavity and an outer cavity. The electronic lock 30 includes a rotating shaft 31 and a main body 32, the rotating shaft 31 extends from the main body 32, the main body 32 is located in the inner cavity, and the partition 20 is provided with a through hole 21 and extends to the outer cavity.

[0031] The charging gun includes a gun body 10, a partition 20 and an electronic lock 30, wherein the gun body 10 has a hollow cavity, the partition 20 is arranged on the gun body 10 and divides the hollow cavity into an inner cavity and an outer cavity, the electronic lock 30 includes a rotating shaft 31 and a main body 32, the main body 32 is located in the inner cavity, the partition 20 is provided with a through hole 21, the rotating shaft 31 is penetrated by the through hole 21 and extends to the outer cavity, so that the hollow cavity of the gun body 10 is divided into an inner cavity and an outer cavity by the partition 20, and the inner and outer cavities are isolated, and the electronic lock 30 is arranged in the inner cavity, water is blocked by the partition 20 and cannot enter the inner cavity, so that the electronic lock 30 will not be corroded and cause functional failure, thereby ensuring the normal operation of the electronic lock 30 and greatly reducing the risk of water ingress.

[0032] In this embodiment, a locking mechanism is provided in the outer cavity, and the locking mechanism includes a steering member 50, and the rotating shaft 31 is connected to the steering member 50. Further, the locking mechanism also includes a positioning structure and an unlocking member. The positioning structure is provided on the partition 20 and cooperates with the steering member 50. When the rotating shaft 31 and the steering member 50 are assembled in place, the steering member 50 is separated from the positioning structure. The unlocking member is located in the outer cavity and abuts against the steering member 50. The gun body 10 is provided with an avoidance hole. The unlocking member includes a button part, which is accommodated in the avoidance hole. The button part drives the unlocking member to press the steering member 50 inwardly to rotate the steering member 50, thereby driving the electronic lock 30 to unlock. Since the electronic lock 30 is located in the inner cavity and is inconvenient to assemble, by arranging a locking mechanism in the outer cavity, and making the rotating shaft 31 of the electronic lock 30 cooperate with the steering member 50, the rotational mechanical motion of the electronic lock 30 after power is turned on can be transmitted to the outer cavity, and the electronic lock 30 can be smoothly blindly assembled in place with the cooperation of the steering member 50. In addition, by providing an unlocking member, manual unlocking can be performed when a failure occurs in the electronic lock 30 .

[0033] In this embodiment, the partition 20 is a Z-shaped stepped structure, that is, it includes a first section, a second section, and a third section that are bent in sequence. The second section is vertically arranged, the first section and the third section are horizontally arranged, and the through hole 21 is opened in the second section. Specifically, the electronic lock 30 is located in the inner cavity surrounded by the first section, the second section, and the gun body 10, and the steering member 50 is located in the outer cavity surrounded by the second section, the third section, and the gun body 10.

[0034] like Figure 3As shown, the steering member 50 is provided with a matching hole 51, and the rotating shaft 31 extends into the matching hole 51 to be matched with the steering member 50. The matching hole 51 is a non-circular hole and the cross-sectional shape of the rotating shaft 31 is matched with the matching hole 51. In this embodiment, the matching hole 51 is a polygonal hole, and the matching hole 51 and the rotating shaft 31 are matched adaptively, so that they can drive each other to rotate together.

[0035] In this embodiment, the matching hole 51 has a first matching bevel, and the end of the rotating shaft 31 has a second matching bevel that matches the first matching bevel, so that the rotating shaft 31 can smoothly extend into the matching hole 51. Specifically, the first matching bevel and the second matching bevel are both inwardly inclined bevels, and since the rotating shaft 31 is not coaxially arranged with the matching hole 51 in the initial state, the matching of the two matching bevels allows the rotating shaft 31 to smoothly extend into the matching hole 51.

[0036] In this embodiment, the rotating shaft 31 also has a step structure protruding from the outer surface. After the rotating shaft 31 extends into the matching hole 51 by a preset distance, the step structure abuts against the first matching inclined surface to drive the steering member 50 to continue to move. Specifically, the step structure is located in the middle position of the rotating shaft. After the rotating shaft 31 extends into the matching hole 51, the rotating shaft 31 continues to extend into the matching hole 51, so that the step structure abuts against the first matching inclined surface. Under the push of the step structure, the steering member 50 continues to move, and finally the rotating shaft 31 and the steering member 50 are assembled in place.

[0037] like Figure 1 , Figures 3 to 5 As shown, the charging gun also includes a first waterproof seal 40, which is disposed between the rotating shaft 31 and the through hole 21. Specifically, the first waterproof seal 40 is sleeved on the rotating shaft 31, and the rotating shaft 31 and the through hole 21 are sealed when the rotating shaft 31 passes through the through hole 21. By arranging the main body 32 of the electronic lock 30 in the inner cavity and arranging the first waterproof seal 40 at the through hole 21, the gun body 10 is reduced to only one place for waterproof sealing, avoiding the need for waterproof sealing treatment at multiple places of the electronic lock 30, greatly reducing the risk of waterproof failure at multiple places of the electronic lock 30, reducing the number of parts, and enhancing the overall sealing reliability of the electronic lock 30.

[0038] In this embodiment, the first waterproof sealing member 40 is a waterproof sealing ring.

[0039] like Figure 3As shown, the partition 20 is provided with a mounting flange 24, which protrudes from the partition 20 along the periphery of the through hole 21, and the first waterproof seal 40 is accommodated in the mounting flange 24. Specifically, the mounting flange 24 protrudes from the second section of the partition 20 in a direction away from the electronic lock 30, that is, the mounting flange 24 is located in the outer cavity. When assembling, the first waterproof seal 40 is first sleeved on the rotating shaft 31, and then the rotating shaft 31 is extended into the through hole 21, so that the first waterproof seal 40 enters the mounting flange 24 and achieves sealing through radial extrusion.

[0040] Further, such as Figure 5 As shown, the first waterproof seal 40 has a sealing flange 41, and the sealing flange 41 protrudes circumferentially from the peripheral side surface of the first waterproof seal 40. Through the above arrangement, the contact area between the first waterproof seal 40 and the inner wall surface of the mounting flange 24 can be reduced and the friction force can be increased, thereby improving the sealing and waterproof effect of the first waterproof seal 40.

[0041] like Figure 2 As shown, the inner cavity is provided with a mounting groove 11, and the opening of the mounting groove 11 faces the front end of the gun body 10, that is, the opening of the mounting groove 11 faces the gun head 80 of the charging gun.

Through the above arrangement, the main body 32 can slide smoothly into the mounting groove 11.

[0042] like Figure 2 As shown, the partition 20 is provided with a guide rib plate 22, which protrudes from the inner side of the partition 20 and surrounds the mounting groove 11. Further, the main body 32 is fixed to the guide rib plate 22 by a fastener 100. In this embodiment, the fastener 100 is a screw, and the main body 32 and the guide rib plate 22 are respectively provided with a through hole and a threaded mounting hole, and the screw passes through the through hole and the threaded mounting hole in sequence to fix the main body 32 to the guide rib plate 22.

[0043] like Figure 2 As shown, the partition 20 is provided with a first guide rib 23, the first guide rib 23 is located in the installation groove 11, and the main body 32 is provided with a second guide rib 321, which is arranged corresponding to the first guide rib 23 and is limited and stopped in a direction perpendicular to the rotation shaft 31, and is used to guide the main body 32 to enter the installation groove 11. Through the above arrangement, the main body 32 can slide smoothly into the installation groove 11.

[0044] like Figure 4 As shown, the charging gun further includes a gun head 80 and a second waterproof seal 60. The gun head 80 is detachably connected to the front end of the gun body 10. The second waterproof seal 60 is arranged at the connection between the gun head 80 and the gun body 10, so as to achieve sealing and waterproofing through radial extrusion.

[0045] like Figure 4 As shown, the charging gun also includes a charging cable 90 and a third waterproof seal 70. The charging cable 90 is inserted into the rear of the gun body 10. The third waterproof seal 70 is arranged between the charging cable 90 and the gun body 10, so as to achieve sealing and waterproofing through radial extrusion. By providing the second waterproof seal 60 and the third waterproof seal 70, the front end and the rear end of the gun body 10 are sealed and waterproofed, and the overall sealing and waterproofing effect of the electronic lock 30 is further enhanced.

[0046] In this embodiment, the first waterproof seal 40 , the second waterproof seal 60 and the third waterproof seal 70 are all silicone sealing rings.

[0047] In this embodiment, at least a portion of the partition 20 extends along the length direction of the gun body 10, so that the outer cavity and the inner cavity are separated from each other, the inner cavity connects the front and rear ends of the gun body 10, and at least a portion of the gun head 80 and at least a portion of the charging cable 90 are accommodated in the inner cavity. Specifically, the first section of the partition 20 extends along the length direction of the gun body 10, that is, it is horizontally arranged, so as to divide the hollow cavity into an outer cavity and an inner cavity from top to bottom, a portion of the gun head 80 extends into the front inner cavity and is connected to the front end of the gun body 10, and a portion of the charging cable 90 extends into the rear inner cavity and is connected to the rear end of the gun body 10, that is, the tail end.
