At the same time, a certain space is left between the rear view mirror assembly 11 and the accommodating case 13, so that the mirror 111 has a necessary movable range, i.e., can freely rotate within the space.

Further, when an external force acts on any portion of the mirror 111, and a force in a proper direction is given according to the requirement of a user, the whole rearview mirror assembly 11 can rotate in a circumferential direction and can rotate towards or away from the accommodating housing 13 by taking the connecting piece 12 on the accommodating housing 13 as a fulcrum, so that the position of the rearview mirror assembly 11 relative to the accommodating housing 13 can be adjusted from various angles, and the aim of observing the conditions outside the vehicle in multiple directions is achieved through direction adjustment of the mirror 111.

Further, referring to fig. 1 and fig. 4 to 6, the striker assembly 14 includes a striker 144 and a protective housing 146, one end of the protective housing 146 is accommodated in the accommodating housing 13, the other end is exposed from the accommodating housing 13 to the outside of the accommodating housing 13, a channel 1461 penetrating the protective housing 146 is provided on the end surface of the other end, the channel 1461 allows the striker 144 to pass through for breaking a window, the other end of the protective housing 146 exposed from the accommodating housing 13 is used for striking glass during the window breaking operation, the exposed part of the accommodating housing 13 is retracted into the accommodating housing 13, and the striker 144 passes through the channel 1461 to give a huge impact force to a window.

Further, referring to fig. 1, 5 and 6, the striker assembly 14 further includes a first elastic member 141 and a stopper 143, the stopper 143 being located in the housing 13 to fix an end of the striker 144 remote from the tip of the striker 144. The protective case 146 is partially exposed outside the case in the axial direction of the striker 144, and the striker 144 is disposed between the stopper 143 and the protective case 146 and accommodated in the channel 1461. The first elastic member 141, specifically, a spring, is sandwiched between the protective housing 146 and the limiting stopper 143, and forms a first yielding channel 1461 along the axial direction, and the striker 144 is located in the first yielding channel 1461.

In addition, referring to fig. 5 and 6, the striker assembly 14 further includes a slider 145 and a second elastic member 142, wherein the slider 145 is capable of moving around the end of the striker 144 near the channel 1461 along the axial direction of the striker 144, the second elastic member 142, in particular, a spring, is disposed between the slider 145 and the stopper 143, and forms a second yielding channel 1461 along the axial direction, and the first elastic member 141 and the striker 144 are disposed in the second yielding channel 1461.

Further, referring to fig. 5 and 6, the axial direction of the striker 144 is offset from the axial direction of the channel 1461, so that the needle tip is not aligned with the channel 1461 on the protective housing 146 in a natural state, and is inclined, so that the needle tip of the striker 144 is not easy to pass through the channel 1461 to be exposed when the protective cover is not subjected to the window breaking impact force under normal conditions, thereby preventing injury caused by false touch. This deflection is achieved primarily by the two-stage detent of the end of the striker 144 distal from the needle tip by the stop 143.

Referring to fig. 1, 5 and 6, when the window breaking process is performed, one end of the protective housing 146 exposed outside the accommodating case 13 is smashed to glass, the protective housing 146 accommodated in the accommodating case pushes and compresses the second elastic member 142, the exposed portion of the protective housing 146 moves into the accommodating case, after a certain distance of inward movement, the sliding block 145 abuts against the protective housing 146, at this time, the sliding block 145 compresses the first elastic member 141 to enable the sliding block 145 to move towards the side close to the limiting stopper 143, meanwhile, the protective housing 146 also moves continuously, the sliding block 145 contacts with the side wall, the side wall gives the sliding block 145 a force to enable one end of the needle tip of the firing pin 144 to shift to the position where the axial direction of the firing pin 144 coincides with the axial direction of the channel 1461, and finally the needle tip of the firing pin 144 is exposed from the channel 1461 under the combined action of the first elastic member 141, the second elastic member 142, the sliding block 145, the protective housing 146 and the like. In contrast, when the window breaking process is completed, the window breaking force is eliminated, the restoring force given by the first elastic member 141 returns the slider 145, the restoring force given by the second elastic member 142 returns the protective housing 146, and the window breaking assembly is all restored to the state before breaking the window.

Further, referring to fig. 5 and 7, an avoidance groove 1321 is formed in the inner wall of the accommodating housing 13, and one end of the slider 145, which can drive the striker 144 to be away from the stopper 143 when moving toward the side away from the stopper 143, is accommodated in the avoidance groove 1321. The avoiding groove 1321 has an accommodating effect on the sliding block 145 on one hand, and on the other hand, the outward expansion of the avoiding groove 1321 relative to the wall of the inward-sinking area provided for accommodating the whole firing pin assembly 14 inevitably leads to a junction turning structure, and in the window breaking process, the sliding block 145 moves to the side of the limiting baffle 143 to the junction, so that the sliding block 145 receives the force of the side wall, and the firing pin 144 is driven to deviate to enable the axial direction of the firing pin 144 to coincide with the axial direction of the channel 1461, thereby realizing window breaking.

Further, referring to fig. 8, the window breaking hammer 1 further includes a sliding base 15, the sliding base 15 includes a sliding housing 151 and an adhesive plate 152, the sliding housing 151 is located at a side of the housing 13 away from the rearview mirror assembly 11, so that the sliding base 15 is detachably connected with the housing 13 of the window breaking hammer 1, the adhesive plate 152 is further disposed at a side of the sliding housing 151 away from the housing 13, the adhesive plate 152 can be designed into a form of release paper and an adhesive panel, when needed, the release paper can be torn off, so that the adhesive plate 152 has adhesive capability, and the window breaking hammer 1 and an in-vehicle component such as a saddle can be adhered and fixed.
