Description

Technical Field

[0001] The utility model relates to the technical field of charging gun locking guns, and in particular to a charging gun locking gun structure. Background Art

[0002] The charging gun of new energy vehicles is a device used to connect the charging pile and the vehicle for charging. The charging gun is the charging interface of the electric vehicle. According to the voltage, it is divided into DC charging gun and AC charging gun. The DC charging gun is high-voltage charging and is used to charge the battery; the AC charging gun is used to charge the on-board charger.

[0003] As disclosed in patent publication number CN220774862U, a locking gun assembly of a charging gun includes a locking hook and a pressing piece, both of which are located inside the gun head of the charging gun, the locking hook is connected to the pressing piece, and the pressing piece provides a force to the locking buckle to enable the locking hook to lock or detach from the lock of the vehicle charging interface. This locking gun assembly can be quickly unlocked by pressing on the surface of the gun body. However, when the locking gun assembly is in use, the head of the hook strip is pulled during the long-term plugging and unplugging of the charging gun, which can easily cause the head of the hook strip to break, thereby affecting the self-locking function of the charging gun. Since the hook strip is an integral design, it is inconvenient to replace. For this reason, we propose a charging gun locking gun structure to solve the above problems. Utility Model Content

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-4 A charging gun lock structure includes a lock gun hook strip 1, a plug-in column 2 is inserted into the lock gun hook strip 1, and a connecting mechanism 3 is fixedly connected to the outer end of the plug-in column 2, a hook head assembly 4 is installed on the surface of the connecting mechanism 3, a pushing block 5 is installed inside the plug-in column 2, and the surface of the pushing block 5 abuts against the limiting mechanism 6. By squeezing the limiting mechanism 6 by the pushing block 5, the limiting mechanism 6 can be easily extended from the plug-in column 2, which is convenient for the locking gun hook strip 1 and the plug-in column 2 to be engaged.

[0027] Further, see Figure 3 and Figure 4 It can be known that the connecting mechanism 3 includes a connecting block 31, the outer end of the plug-in column 2 is fixedly connected to the connecting block 31, and the internal thread of the connecting block 31 is penetrated by a pushing stud 32. By inserting the pushing stud 32 into the connecting block 31, the pushing block 5 can be easily pushed to move in the plug-in column 2.

[0028] Further, see Figure 3 and Figure 4It can be known that the hook head assembly 4 includes a limiting hook head 41, and the limiting hook head 41 is installed on the surface of the connecting block 31 through the mounting bolts 33, and two groups of mounting bolts 33 are inserted in the limiting hook head 41. Through the two groups of mounting bolts 33 inserted in the limiting hook head 41, the connecting block 31 and the limiting hook head 41 can be conveniently connected.

[0029] Further, see Figure 1 and Figure 3 It can be known that a groove is provided on the outer side of the limiting hook head 41, and an anti-slip pad 42 is glued to the inner wall of the groove. The surface of the anti-slip pad 42 is provided with anti-slip grooves. The groove provided on the outer side of the limiting hook head 41 can conveniently accommodate the pushing stud 32 and the mounting bolt 33.

[0030] Further, see Figure 3 and Figure 4 It can be known that a groove compatible with the plug-in column 2 is provided at the end of the gun lock hook strip 1, a through groove is provided inside the plug-in column 2, and the inner wall of the through groove contacts the surface of the push block 5. The plug-in column 2 can be inserted into the groove through the groove at the end of the gun lock hook strip 1, and a notch compatible with the telescopic bayonet 61 is provided on the inner wall of the groove, so that the telescopic bayonet 61 can be inserted into the notch to limit the plug-in column 2 in the gun lock hook strip 1.

[0031] Further, see Figure 3 and Figure 4 It can be known that the limiting mechanism 6 includes a telescopic pin 61, the cross-section of the pushing block 5 is set to a triangle, and both sides of the pushing block 5 are in contact with the end of the telescopic pin 61, the outer end of the end of the telescopic pin 61 is fixedly connected with a guide slider 62, and a guide column 63 is inserted inside the guide slider 62, and a return spring 64 is welded between the inner wall of the plug-in column 2 and the guide slider 62. By making the two sides of the pushing block 5 in contact with the end of the telescopic pin 61, the two groups of telescopic pins 61 can be pushed out of the plug-in column 2 when the pushing block 5 moves.

[0032] Further, see Figure 3 and Figure 4 It can be known that the guide column 63 is set to a cylindrical shape, and a circular hole matched with the guide column 63 is opened inside the guide slider 62.

[0033] Working principle: When the utility model is in use, when the limit hook head 41 needs to be replaced, according to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4, by inserting the plug-in column 2 into the gun lock hook strip 1, and passing the push stud 32 through the limiting hook head 41 and the anti-skid pad 42 through the connecting block 31, the push stud 32 can be made to enter the plug-in column 2. When the push stud 32 pushes the pushing block 5 to move, the pushing block 5 can squeeze the two sets of telescopic bayonet pins 61. When the telescopic bayonet pins 61 are squeezed, they will extend from the inside of the plug-in column 2 and be inserted into the gun lock hook strip 1. When the telescopic bayonet pins 61 move, the guide slider 62 can slide along the surface of the guide column 63, so that the reset spring 64 is in a compressed state. At this time, the plug-in column 2 can be limited in the gun lock hook strip 1. At the same time, the mounting bolt 33 is passed through the limiting hook head 41 and the anti-skid pad 42 and is threadedly connected to the connecting block 31, which can facilitate the positioning and installation of the limiting hook head 41.
