Description

Technical Field

[0001] The present application relates to the technical field related to new energy vehicle accessories, and in particular to a charging gun. Background Art

[0002] The charging gun is used to electrically connect to the charging port on a new energy vehicle to charge the new energy vehicle. Since the charging ports of new energy vehicles at home and abroad do not adopt a unified manufacturing standard, the charging gun does not match the design of the charging port of foreign new energy vehicles, resulting in the charging gun being unable to connect to the charging port of the new energy vehicle, making it impossible for the charging gun to charge the new energy vehicle. Therefore, people usually connect an adapter to the charging gun to match the different charging ports of new energy vehicles to charge the new energy vehicle.

[0003] At present, the assembly between the charging gun and the adapter in the existing new energy vehicles is achieved by plugging the charging gun and the adapter together and then clamping the adapter with the clip on the charging gun. However, since the adapter is fixed on the charging gun using the clip on the charging gun, once the clip is tilted during use of the charging gun, the adapter is easily displaced on the charging gun, making the electrical connection between the charging gun and the adapter unstable, resulting in the charging gun using the adapter cannot work properly. Utility Model Content

[0004] In view of this, it is necessary to provide a charging gun that can solve the above technical problems.

[0005] In order to solve the above technical problems, this application provides the following technical solutions:

[0006] A charging gun, used in new energy vehicles, comprising:

[0007] A charging gun body, comprising a charging gun body and an adapter, wherein the adapter is detachably connected to the charging gun body, wherein a buckle is provided on the charging chamber body, and the buckle can be engaged with the adapter to lock the adapter connected to the charging gun body to the charging gun body;

[0008] A locking sleeve is sleeved on the adapter, a protruding cavity shell is formed on the locking sleeve, and a locking piece is detachably mounted on the protruding cavity shell. When the locking piece is mounted on the protruding cavity shell, the locking piece can be connected to the protruding cavity shell, and the locking piece is at least partially arranged on a side of the snap-fit ​​piece away from the adapter and abuts against the snap-fit ​​piece, so as to limit the snap-fit ​​piece to the adapter.

[0009] It can be understood that the locking piece connected to the protruding cavity shell is used to abut the snap-on piece on the charging gun body, so that the snap-on piece on the charging gun body can always be pressed against the adapter by the locking piece. In this way, the adapter can be prevented from shifting on the charging gun body, ensuring the stability of the electrical connection between the charging gun body and the adapter, and ensuring the normal operation of the charging gun using the adapter.

[0010] In one embodiment, the locking member can be plugged into and matched with the protruding cavity shell;

[0011] Wherein, a hook plate is formed on the locking member, and a slot is formed on the outer peripheral wall of the protruding cavity shell. The hook plate can be engaged with the slot to limit the locking member to the protruding cavity shell.

[0012] It can be understood that the locking member is assembled on the lock sleeve by utilizing the snap fit between the hook plate on the locking member and the snap fit on the protruding cavity shell, so as to facilitate the assembly connection of the locking member on the lock sleeve.

[0013] In one embodiment, the hook plate has a convex buckle, and along the opposite direction of the insertion of the locking member into the protruding cavity shell, the convex buckle can abut against the groove wall of the slot to limit the hook plate to the protruding cavity shell;

[0014] Wherein, one end surface of the convex buckle facing the convex-extension cavity shell is set as an arc surface.

[0015] It can be understood that the end face of the protrusion of the hook plate facing the protruding cavity shell is set as an arc surface, which can facilitate the protrusion of the hook plate to enter the groove of the protruding cavity shell, and facilitate the assembly of the locking piece to the protruding cavity shell; and by utilizing the structural characteristics of the arc surface, the protrusion of the hook plate can be easily pulled out from the groove of the protruding cavity shell, and then the locking piece can be easily removed from the protruding cavity shell; in this way, the disassembly and assembly of the locking piece on the protruding cavity shell is convenient to meet people's usage needs.

[0016] In one embodiment, the locking member has an abutment surface, and the locking member can abut against the buckle member through the abutment surface;

[0017] The distance between the abutment surface and the upper axis of the locking sleeve can be adjusted.

[0018] It can be understood that since the distance between the abutment surface on the locking piece and the axis line on the locking sleeve can be adjusted, the abutment surface on the locking piece can be adapted to different height positions of the snapping piece after being snapped into place with the adapter. In this way, the locking piece can be pressed and limited with the snapping pieces at different heights on the charging gun body, so that the locking sleeve with the locking piece can be adapted to different charging guns.

[0019] In one embodiment, the locking member can be plugged into and matched with the protruding cavity shell;

[0020] Two end surfaces of the locking member along the thickness direction of the locking member can be formed as the abutting surfaces respectively.

[0021] It can be understood that the two end faces of the locking piece along the thickness direction of the locking piece can be formed as abutment surfaces respectively. In this way, the locking piece can be inserted on the front and back sides of the protruding cavity shell to achieve abutment between the locking piece and the snap-on pieces at different heights on the charging gun body for easy adjustment.

[0022] In one of the embodiments, an inserting strip is formed on the locking member, and a slot is formed on the inner peripheral wall of the protruding cavity shell. The slot is matched with the inserting strip, and the inserting strip can be plugged into and matched with the slot.

[0023] It can be understood that the locking piece can be easily assembled to the protruding cavity shell by plugging and matching the inserting strip on the locking piece with the slot on the protruding cavity shell.

[0024] In one embodiment, along the thickness direction of the locking element, a preset gap is formed between the center line of the inserting strip and the center line of the locking element.

[0025] It can be understood that a preset gap is formed between the center line of the insertion strip and the center line of the locking piece, so that the insertion strip is eccentrically arranged to enable the locking piece to abut against the snap-on pieces at different heights on the charging gun body when inserted into the protruding cavity shell. In this way, the structure of the locking piece can be simplified.

[0026] In one of the embodiments, along the insertion direction of the locking member into the protruding cavity shell, the thickness of the inserting strip gradually decreases.

[0027] It can be understood that the thickness of the inserting strip on the locking member gradually decreases along the insertion direction of the locking member into the protruding cavity shell, so that the locking member can be easily inserted into the protruding cavity shell.

[0028] In one embodiment, a hook plate is formed on the locking member, and a slot is formed on the outer peripheral wall of the protruding cavity shell, and the hook plate can be engaged with the slot to limit the locking member to the protruding cavity shell;

[0029] Wherein, the slot width of the locking slot is greater than the thickness of the hook plate.

[0030] It is understandable that the width of the slot on the protruding cavity shell is greater than the thickness of the hook plate on the locking member, so that when the locking member is inserted at the front and back of the protruding cavity shell, the hook plate on the locking member can be engaged with the slot on the protruding cavity shell.

[0031] In one embodiment, the adapter includes a first shell and a second shell, and the first shell and the second shell are connected by ultrasonic welding; wherein the first shell and the second shell are also connected by fasteners.

[0032] It can be understood that on the basis of ultrasonic welding between the first shell and the second shell, the first shell and the second shell are connected with fasteners. In this way, the connection strength between the first shell and the second shell can be improved, and the second shell can be prevented from falling off from the first shell due to external force.

[0033] Due to the application of the above solution, the present application has the following advantages compared with the prior art:

[0034] The charging gun for which protection is requested in the present application uses a locking piece connected to the protruding cavity shell to abut the latch piece on the charging gun body, so that the latch piece on the charging gun body can always be pressed against the adapter by the locking piece. In this way, the adapter can be prevented from shifting on the charging gun body, thereby ensuring the stability of the electrical connection between the charging gun body and the adapter and ensuring the normal operation of the charging gun using the adapter.

[0048] The charging gun for which protection is sought in this application is used in new energy vehicles to charge the new energy vehicles.

[0049] like Figures 1 to 6 As shown, a charging gun provided in an embodiment of the present application includes a charging gun body and a locking sleeve 20, wherein the charging gun body includes a charging gun body 11 and an adapter 12, wherein the adapter 12 is detachably connected to the charging gun body 11, wherein a snap-fitting piece 111 is provided on the charging gun body 11, and the snap-fitting piece 111 can be snapped with the adapter 12 to lock the adapter 12 connected to the charging gun body 11 to the charging gun body 11; the locking sleeve 20 is sleeved on the adapter 12, a protruding cavity shell 21 is formed on the locking sleeve 20, and a locking piece 22 is detachably mounted on the protruding cavity shell 21, when the locking piece 22 is assembled to the protruding cavity shell 21, the locking piece 22 can be connected to the protruding cavity shell 21, and the locking piece 22 is at least partially arranged on a side of the snap-fitting piece 111 away from the adapter 12 and abuts against the snap-fitting piece 111, so as to limit the snap-fitting piece 111 to the adapter 12.

[0050] It can be understood that the locking piece 22 connected to the protruding cavity shell 21 is used to abut the latch 111 on the charging gun body 11, so that the latch 111 on the charging gun body 11 can always be pressed against the adapter 12 by the locking piece 22. In this way, the adapter 12 can be prevented from shifting on the charging gun body 11, ensuring the stability of the electrical connection between the charging gun body 11 and the adapter 12, and ensuring the normal operation of the charging gun using the adapter 12.

[0051] like Figure 1 , Figure 6As shown, in one embodiment, the adapter 12 includes a first shell 121 and a second shell 122, and ultrasonic welding is used between the first shell 121 and the second shell 122; wherein, the first shell 121 and the second shell 122 are also connected by a fastener 123. That is to say, the adapter 12 of this embodiment uses ultrasonic welding between the first shell 121 and the second shell 122, and then uses a fastener 123 to connect the first shell 121 and the second shell 122, so that the connection strength between the first shell 121 and the second shell 122 can be improved, and the second shell 122 can be prevented from falling off from the first shell 121 due to external force. Here, the fastener 123 can be a connecting piece such as a bolt or a screw.

[0052] like Figure 1 As shown, in one embodiment, the locking member 22 can be plugged and matched with the protruding cavity shell 21; a hook plate 221 is formed on the locking member 22, and a slot 211 is formed on the outer peripheral wall of the protruding cavity shell 21, and the hook plate 221 can be plugged and matched with the slot 211 to limit the locking member 22 to the protruding cavity shell 21. In other words, the locking member 22 is specifically assembled on the lock sleeve 20 by using the plug-in fit between the hook plate 221 on the locking member 22 and the slot 211 on the protruding cavity shell 21, so as to facilitate the assembly connection of the locking member 22 on the lock sleeve 20. It should be noted that the locking member 22 is not limited to being assembled to the protruding cavity shell 21 by plugging and matching. For those skilled in the art, the locking member 22 can also be connected to the protruding cavity shell 21 by bolts, screws and other connecting members, which will not be elaborated here.

[0053] In this embodiment, there are two card slots 211 , and the two card slots 211 are respectively located on two sides of the protruding cavity shell 21 .

[0054] like Figure 1 As shown, in one embodiment, there is one hook plate 221. Of course, for those skilled in the art, there may also be two hook plates 221, which are respectively located on both sides of the locking member 22, which will not be elaborated here.

[0055] like Figure 1 , Figure 4As shown, in one embodiment, the hook plate 221 has a convex buckle 2211, and along the opposite direction of the insertion of the locking member 22 into the protruding cavity shell 21, the convex buckle 2211 can abut against the groove wall 2111 of the slot 211 to limit the hook plate 221 to the protruding cavity shell 21; wherein, one end face of the convex buckle 2211 facing the protruding cavity shell 21 is set as an arc surface. That is to say, the convex buckle 2211 of the hook plate 221 is set to an arc surface on one end surface facing the protruding cavity shell 21, so that the convex buckle 2211 of the hook plate 221 can be easily entered into the slot 211 of the protruding cavity shell 21, and the locking piece 22 can be easily assembled to the protruding cavity shell 21; and by utilizing the structural characteristics of the arc surface, the convex buckle 2211 of the hook plate 221 can be easily pulled out from the slot 211 of the protruding cavity shell 21, and then the locking piece 22 can be easily removed from the protruding cavity shell 21; in this way, the disassembly and assembly of the locking piece 22 on the protruding cavity shell 21 can be facilitated to meet people's usage needs.

[0056] like Figure 1 , Figure 4 As shown, in one embodiment, the locking member 22 has a contact surface 222, and the locking member 22 can contact the buckle 111 through the contact surface 222; the distance between the contact surface 222 and the axis of the lock sleeve 20 can be adjusted. Since the distance between the contact surface 222 on the locking member 22 and the axis of the lock sleeve 20 can be adjusted, the contact surface 222 on the locking member 22 can be applied to different height positions of the buckle 111 after being engaged with the adapter 12. In this way, the locking member 22 can be pressed and limited with the buckle 111 at different heights on the charging gun body 11, so that the lock sleeve 20 with the locking member 22 can be applied to different charging guns.

[0057] In this embodiment, the two end surfaces of the locking member 22 along the thickness direction of the locking member 22 can be formed as abutment surfaces 222 respectively. Specifically, the abutment surfaces 222 are respectively a first abutment surface 2221 and a second abutment surface 2222. When in use, first, the locking member 22 is inserted into the protruding cavity shell 21, and the first abutment surface 2221 abuts against the buckle 111 on the charging gun body 11. Then, the locking member 22 is pulled out of the protruding cavity shell 21, and the locking member 22 is turned over and inserted into the protruding cavity shell 21. At this time, the second abutment surface 2222 abuts against the buckle 111 on the charging gun body 11. In other words, the locking member 22 can be inserted on the front and back sides of the protruding cavity shell 21 to reflect the abutment of the buckle 111 at different heights on the charging gun body 11 for easy adjustment.

[0058] like Figure 1As shown, in one embodiment, the width of the slot 211 is greater than the thickness of the hook plate 221. In other words, the width of the slot 211 on the protruding cavity shell 21 is greater than the thickness of the hook plate 221 on the locking member 22, so that when the locking member 22 is inserted into the front and back sides of the protruding cavity shell 21, it is ensured that the hook plate 221 on the locking member 22 and the slot 211 on the protruding cavity shell 21 can be engaged.

[0059] like Figure 3 , Figure 4 As shown, in one embodiment, an inserting strip 223 is formed on the locking member 22, and a slot 212 is formed on the inner peripheral wall of the protruding cavity shell 21, and the slot 212 is matched with the inserting strip 223, and the inserting strip 223 can be plugged into and matched with the slot 212. In other words, the inserting strip 223 on the locking member 22 is plugged into and matched with the slot 212 on the protruding cavity shell 21, so that the locking member 22 can be easily assembled to the protruding cavity shell 21.

[0060] like Figure 5 As shown, in one embodiment, along the thickness direction of the locking member 22, a preset gap is formed between the center line of the inserting strip 223 and the center line of the locking member 22. That is to say, by using the preset gap formed between the center line of the inserting strip 223 and the center line of the locking member 22, the inserting strip 223 is eccentrically arranged, so that when the locking member 22 is inserted into the protruding cavity shell 21, it can abut against the buckle members 111 at different heights on the charging gun body 11, so that the structure of the locking member 22 can be simplified.

[0061] like Figure 5 As shown, in one embodiment, the thickness of the inserting strip 223 gradually decreases along the insertion direction of the locking member 22 into the male and female housing 21. In this way, the locking member 22 can be easily inserted into the male and female housing 21.

[0062] In summary, the charging gun for which protection is requested in the present application uses the locking piece 22 connected to the protruding cavity shell 21 to abut the latch 111 on the charging gun body 11, so that the latch 111 on the charging gun body 11 can always be pressed against the adapter 12 by the locking piece 22. In this way, the adapter 12 can be prevented from shifting on the charging gun body 11, thereby ensuring the stability of the electrical connection between the charging gun body 11 and the adapter 12 and ensuring the normal operation of the charging gun using the adapter 12.

[0063] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
