In addition, the side wall of the moving member 122 is provided with a guide groove 170, and the extending direction of the guide groove 170 is consistent with the moving direction of the locking member 116; the locking member 116 is provided with a second protrusion 130, and the second protrusion 130 is located in the guide groove 170, so that the second protrusion 130 is slidably connected with the guide groove 170. Thus, in use, locking member 116 is movable relative to movable member 122 by an external force, thereby ensuring that locking member 116 can be retracted into mounting member 110 even if a user inadvertently closes locking assembly 108, thereby ensuring that locking member 116 and mounting member 106 can be coupled in a limited position.

Specifically, when the door body assembly 104 is opened, the first elastic member 114 abuts between the moving member 122 and the lock member 116. At this time, the second protrusion 130 is located at the middle of the guiding groove 170 or at the first end of the guiding groove 170 close to the bottom of the mounting member 110 to ensure that the locking member 116 can be retracted into the mounting member 110 under the driving of external force, thereby ensuring that the locking member 116 can still be locked with the fixing member 106 even if the user inadvertently closes the locking assembly 108.

In addition, when the locking member 116 moves, the second protrusion 130 moves along the guide groove 170, and further, the second protrusion 130 and the guide groove 170 are matched to perform a certain limiting and guiding function, so that the smooth and stable operation of the locking member 116 is improved.

In one possible embodiment, as shown in fig. 4, the locking member 116 further includes: a drive ramp 132 against which the fastener 106 can abut to drive the locking member 116 to move relative to the mounting member 110.

In this embodiment, the locking member 116 further includes a drive ramp 132. After the door body assembly 104 is opened, if a user triggers the locking assembly 108 by mistake, the locking member 116 extends out of the mounting member 110. At this time, in the process of closing the door assembly 104, the user can directly drive to close the door assembly 104 without pressing the pressing piece 120 again, which is more convenient for the user to operate.

Specifically, during the process of closing the door body assembly 104 by a user, the fixing element 106 first contacts with the driving inclined surface 132 of the locking element 116, the driving inclined surface 132 decomposes the force applied by the fixing element 106 to the locking element 116 into a lateral component and a vertical component, and the vertical component can be used for offsetting the pushing force applied by the first elastic element 114 to the locking element 116, so that the locking element 116 moves under the action of the vertical component, and the locking element 116 retracts into the mounting element 110. At this time, the user can close the door assembly 104.

In one possible embodiment, as shown in fig. 4 and 9 in combination, the locking assembly 108 further includes: a second resilient member 134, the second resilient member 134 being disposed within the mounting member 110 and being connected to the driving member 112 and the mounting member 110 for resetting the locking member 116; at least a portion of the first elastic member 114 is located inside the locking member 116, and the second elastic member 134 is sleeved on the locking member 116.

The second elastic element 134 is disposed in the mounting element 110 and abuts against the moving element 122 of the driving element 112 and the cover plate 140 of the mounting element 110. Thus, the first elastic member 114 and the second elastic member 134 cooperate to further improve the stability of the locking member 116.

In particular, in the process of pressing the pressing member 120, before the pressing member 120 contacts the moving member 122, the pressing member 120 presses the second elastic member 134, and the second elastic member 134 is in a compressed state; after the pressing member 120 contacts the moving member 122, the pressing member 120 simultaneously presses the first elastic member 114 and the second elastic member 134, and both the first elastic member 114 and the second elastic member 134 are in a compressed state.

Specifically, when the moving element 122 is limited at the end of the guiding structure 118, the first elastic element 114 and the second elastic element 134 in the compressed state both apply a pushing force to the moving element 122, so that the moving element 122 is stably limited at the end of the guiding structure 118. After pressing the pressing piece 120 again, the mover 122 rotates and disengages from the end of the guide structure 118; at this time, the first elastic member 114 and the second elastic member 134 are engaged with each other in the compressed state, thereby restoring the moving member 122 to the previous position. In this process, due to the cooperation of the first elastic member 114 and the second elastic member 134, the thrust force on the driving member 112 can be greatly increased, and the stability of the locking member 116 can be further improved.

As shown in fig. 4, 9 and 12, in one possible embodiment, the mounting member 110 includes: the driving device comprises a fixed bracket 136, a third opening 138, a cover plate 140 and a fourth opening 142, wherein the third opening 138 is arranged on the fixed bracket 136, and the driving member 112 is arranged in the third opening 138; the cover plate 140 is connected with the fixing bracket 136; the fourth opening 142 is disposed on the cover plate 140, and the locking member 116 can be disposed through the fourth opening 142.

In this embodiment, the mounting member 110 includes a fixed bracket 136, a first opening 184, a cover plate 140, and a second opening 188. Wherein, the fixing bracket 136 can ensure the stable installation of the whole locking assembly 108; the cover plate 140 is coupled to the fixing bracket 136 such that the cover plate 140 cooperates with the fixing bracket 136 to secure the locking member 116 and the first elastic member 114.
