Preferably, the trigger switch 20 comprises an opto-electronic switch.

The elastic compression restoring member 50 is connected between the first position-limiting portion 32 and the housing 10, and the elastic compression restoring member 50 is used for providing an elastic restoring force for moving the moving member 30 and the impact prevention plate in the first direction and in a direction away from the trigger switch 20.

Therefore, the trigger switch 20, the moving part 30, the trigger part 40 and the elastic compression resetting part 50 are installed on the shell 10 in a concentrated manner, when the sweeping robot collides with surrounding obstacles, the trigger part 40 can move along with the moving part 30 along the first direction to trigger the trigger switch 20, and after the sweeping robot is controlled to change the direction, the elastic compression resetting part 50 can provide elastic restoring force for enabling the moving part 30 and the anti-collision plate to move towards the direction far away from the trigger switch 20 in time, and the resetting process is timely and very stable and balanced. The collision switch assembly 100 provided by the application can reset timely, stably and balance without additionally arranging a reset structure outside the collision switch.

In addition, since the elastic compression restoring member 40 is located at one side of the moving body 31 in the second direction, the movement of the moving body 31 is not disturbed, and the moving stability of the moving body 31 is improved.

Referring again to fig. 1 and 2, in some embodiments, the housing 10 includes a first housing 12 and a second housing 13, and the first housing 12 and the second housing 14 are configured to mate in a first direction to form the accommodating cavity 11 of the housing 10. In this way, the installation of the trigger switch 20, the trigger member 40, the moving member 30 and the elastic compression restoring member 50 with respect to the housing 10 can be facilitated.

Further, one of the first housing 12 and the second housing 13 is provided with a first locking portion 14, the other of the first housing 12 and the second housing 13 is provided with a second locking portion 15, and the first locking portion 14 and the second locking portion 15 cooperate to lock the first housing 12 and the second housing 13. In this way, the reliability of the mating of the first housing 12 and the second housing 13 can be improved, and the stability of the overall structure of the crash switch assembly 100 can be improved.

In one embodiment, the first locking portion 14 comprises a first snap and the second locking portion 15 comprises a second snap, the first snap and the second snap being snap-fit. The mode has simple structure and convenient operation.

In some embodiments, the housing 10 further defines a connection through hole 105 communicating with the accommodating cavity 11, the crash switch assembly 100 further includes a connection cover plate covering the connection through hole 105, and the trigger switch 20 is electrically connected to an external main controller via the connection cover plate. Therefore, the connection through hole 105 can be shielded while the trigger switch 20 is electrically connected with the master controller, and the situation that the trigger switch 20 is directly connected with the master controller through the connection through hole 105 is avoided, the connection through hole 105 is exposed, so that foreign matters or light rays easily enter the accommodating cavity 11 to affect the trigger accuracy of the trigger switch 20 is avoided. Specifically, a positioning groove is formed in the casing 10, the positioning groove is arranged around the connecting through hole 105 and communicated with the connecting through hole 105, and the connecting cover plate is circumferentially installed in the positioning groove. Thus, the positioning manner of the opposite connecting through holes 105 of the connecting cover plate is simple and reliable. As shown in fig. 5, in other embodiments, the trigger switch 20 is covered at the connecting through hole 105, and the trigger switch 20 is electrically connected to the external main controller through the connecting through hole 104, so that the structure of the crash switch assembly 100 is simplified by covering the connecting through hole 105 with the trigger switch 20 itself.

In some embodiments, a second position-limiting portion is disposed in the accommodating cavity 11 of the housing 10, the second position-limiting portion is disposed opposite to the first position-limiting portion 32 along the first direction, and the elastic compression restoring element 50 is connected between the first position-limiting portion 32 and the second position-limiting portion. Specifically, the second limiting portion is a first inner wall 16 in the accommodating cavity 11 of the housing 10.

In some embodiments, the trigger 40 is located on a side facing away from the first position-limiting portion 32 in the second direction relative to the axis of the moving body 31. Thus, the two sides of the movable body 31 along the two directions are evenly stressed, and the triggering element 40 and the elastic compression resetting element 50 keep the distance as far as possible without mutual interference. As shown in fig. 6 to 8, in other embodiments, the trigger 40 is located at an end of the moving body 31 in the first direction. Thus, the size of the impact switch assembly 100 in the second direction is reduced while the structure is simplified.

In some embodiments, the displacement member 30 is integrally formed with the trigger member 40. Thus, the structural stability of the moving member 30 and the triggering member 40 can be improved.

Referring to fig. 3 and 4 again, in some embodiments, the housing 10 has a first inner wall 16 and a second inner wall 17 that are disposed opposite to each other along the first direction, the first position-limiting portion 32 and the elastic compression restoring member 50 are both disposed between the first inner wall 16 and the second inner wall 17, and the elastic compression restoring member 50 is pre-pressed between the first inner wall 16 and the first position-limiting portion 32 to provide a pre-pressure for making one side of the first position-limiting portion 32 away from the elastic compression restoring member 50 abut against the second inner wall 17 along the first direction. In this way, when the moving member 30 is not moved in the first direction by an external force, the first position-limiting portion 32 is kept at the initial position by the pre-pressure of the elastic compression restoring member 50, so that the working stability of the crash switch assembly 100 is improved. In addition, the moving member 30 may be provided with a holding force in contact with the crash pad.

In some embodiments, the axis of the trigger 40 relative to the moving body 31 is located on a side of the moving body 31 facing away from the first limiting portion 32 along the second direction, a third inner wall is disposed in the accommodating cavity 11 of the housing 10 and facing the trigger 40 along the first direction, and the elastic compression resetting member 50 is pre-pressed between the first limiting portion 32 and the housing 10 to provide a pre-pressure for making the trigger 40 abut against the third inner wall along the first direction and in a direction away from the trigger switch 20. In this way, when the moving member 30 is not moved in the first direction by an external force, the triggering member 40 is maintained at the initial position by the pre-pressure of the elastic compression restoring member 50, and the operation stability of the crash switch assembly 100 is improved.

Further, the first position-limiting portion 32 has a first side wall, the first side wall abuts against the second inner wall 17 along the first direction, the trigger 40 has a second side wall, the second side wall abuts against the third inner wall along the first direction, and the first side wall and the second side wall are arranged in parallel and level along the second direction. In this way, the third inner wall and the second inner wall 17 are also arranged flush in the second direction, in particular, the third inner wall and the second inner wall 17 are the same inner wall. Therefore, the trigger 40 and the first limiting portion 32 can be abutted simultaneously, the abutting area is increased, and the pre-pressing stability is improved.

Referring to fig. 2 again, in some embodiments, the moving member 30 further includes a first guiding portion 33 extending along the first direction, one end of the first guiding portion 33 is connected to the first limiting portion 32, the first guiding portion 33 extends along the first direction, and the elastic compression restoring member 50 is sleeved on the first guiding portion 33. By providing the first guide portion 33, the reliability of the elastic compression restoring member 50 in compression and extension restoration can be improved. In one embodiment, the elastic compression restoring element 50 includes a compression spring, and the compression spring is sleeved on the first guiding portion 33. Specifically, the first guide portion 33 has a cylindrical shape, and preferably, the first guide portion 33 has a cylindrical shape.

In some embodiments, the resilient compression return element 50 at least partially overlaps the displacement body 31 in the second direction. In this manner, the size of the crash switch assembly 100 in the second direction may be reduced to accommodate different applications. Specifically, the first guide portion 33 at least partially overlaps the moving body 31 in the second direction.

Referring to fig. 3 and 4 again, in some embodiments, the housing 10 includes a first matching portion 18, and an end of the first guiding portion 33 away from the first limiting portion 312 along the first direction is matched with the first matching portion 18 to guide the moving member 30 to move along the first direction. Thus, the first guiding portion 33 can be fully utilized to ensure the stable moving process of the moving member 30, and at the same time, to stabilize the compressing and restoring processes of the elastic compression restoring member 50. Further, the second position-limiting portion is disposed around the first fitting portion 18. In this way, the stability of the compression and restoration process of the elastic compression restoring member 50 during the engagement of the first guide portion 33 with the first engaging portion 18 can be further improved.

In one embodiment, the first matching portion 18 includes a first matching groove 182 having a first opening 181, and the first guiding portion 33 is matched with the first matching groove 182 through the first opening 181. The structure of the matching groove is simple, and the guiding performance is stable and reliable.

Thus, the structure of the first matching groove 182 is fully utilized, the moving part 30 is limited in movement in the first direction, and meanwhile, the amount of the elastic compression resetting part 50 compressed is determined, so that the elastic resetting capacity of the elastic compression resetting part is determined, and the resetting effect is good. It should also be noted that when the first guiding portion 33 abuts against the first limiting portion, the trigger switch 20 should be triggered by the trigger 40.

In other embodiments, the first matching portion 18 includes a first matching through hole, and the first guiding portion 33 is disposed through the first matching through hole. It will be appreciated that the outer diameter of the resilient compression return element 50 is greater than the inner diameter of the first mating through hole. In some embodiments, the shape of the first mating through hole matches the cross-sectional shape of the first guide portion 33. The mode that sets up first cooperation through-hole is simple, and the direction is reliable and stable.

Further, a fourth limiting portion is disposed at an end of the first guiding portion 33, and the fourth limiting portion can abut against an outer edge of the first matching through hole to limit the moving member 30 from being separated from the first matching through hole along the first direction. Thus, the first guide portion 33 is prevented from being separated from the first fitting through hole in the first direction by the restoring force of the elastic compression restoring member 50, and the operational reliability of the crash switch assembly 100 is improved. Specifically, the spacing portion of fourth includes the elasticity buckle, and the cooperation of elasticity buckle and first cooperation through-hole joint, and the elasticity buckle is operable to be taken off with first cooperation through-hole along the radial deformation of first cooperation through-hole.

Because the first guiding portion 33 and the second guiding portion 34 are located at two sides of the first limiting portion 32 along the first direction, the guiding of the first limiting portion 32 along the two sides of the first direction can be balanced, and the stability of the moving process of the moving member 30 can be further improved.

Further, the second matching portion 101 includes a second matching through hole 1011, the second guiding portion 34 penetrates through the second matching through hole 1011 and protrudes out of the outer side of the housing 10 through the second matching through hole 1011, one end of the second guiding portion 34 facing the outer side of the housing 10 is a contact end 341, and the moving member 30 is in contact with the anti-collision plate through the contact end 341. Specifically, the housing 10 has a fourth inner wall, and the second matching through hole 1011 is opened on the fourth inner wall, preferably, the fourth inner wall is located between the second inner wall 17 and the third inner wall along the second direction, or is the same inner wall as the second inner wall 17 and the third inner wall. Specifically, the shape of the second fitting through-hole 1011 matches the sectional shape of the second guide portion 34. The mode of setting up second cooperation through-hole 1011 is simple, and the direction is reliable and stable.

Further, one end of the second guide portion 34 is connected to one end of the moving body 31. Thus, the structural strength of the moving body 31 can be enhanced, and the moving stability of the moving body 31 can be improved.

In some embodiments, the moving member 30 further includes a third guiding portion 35 extending along the first direction, an end of the third guiding portion 35 is connected to an end of the moving body 31 facing away from the second guiding portion 34 along the first direction, the housing 10 is further provided with a third matching portion 102, and the third matching portion 102 is matched with the third guiding portion 35 to guide the moving member 30 to move along the first direction. Since the third guide portion 35 and the second guide portion 34 are located at two ends of the moving body 31 along the first direction, the guiding of the moving body 31 along two sides of the first direction can be balanced, and the stability of the moving process of the moving member 30 can be further improved. It is noted that when the trigger 40 is located at the end of the moving body 31 in the first direction, the third guide portion 35 need not be provided.
