[0034] To solve the above problems, the present disclosure exemplary embodiments first provide a collision detection assembly 10, as shown in FIG. 1, FIG. 2 and FIG. 3, the collision detection assembly 10 comprises: a first detection piece 11, a second detection piece 12 and an electrical connecting piece 13, the first detection piece 11 is used for detecting the collision of the cleaning device 100 in a first direction; the second detection piece 12 is used for detecting the collision of the cleaning device 100 in a second direction, the second detection piece 12 comprises a pressure bearing buffer piece 121 and a pressure bearing sensing module 122, the pressure bearing sensing module 122 is arranged between the first detection piece 11 and the pressure bearing buffer piece 121; the electrical connecting piece 13 is arranged between the first detection piece 11 and the pressure bearing buffer piece 121, and the electrical connecting piece 13 and the pressure bearing sensing module 122 are electrically connected.
[0035] The collision detection assembly 10 provided by the present disclosure comprises a first detection piece 11, a second detection piece 12 and an electrical connecting piece 13, the first detection piece 11 is used for detecting the collision of the cleaning device 100 in a first direction, and the second detection piece 12 is used for detecting the collision of the cleaning device 100 in a second direction, the detection of the collision of the cleaning device 100 and the obstacle is realized through the first detection piece 11 and the second detection piece 12, which can be used for obstacle avoidance of the cleaning device 100, and the problem that the cleaning device 100 is stuck and cannot walk is avoided. Further, by arranging the electrical connecting piece 13 connected with the pressure bearing sensing module 122 between the first detection piece 11 and the pressure bearing buffer piece 121, the compactness of the structure of the cleaning device 100 is improved, and the space in the cleaning device 100 is saved.
[0036] The parts of the collision detection assembly 10 provided by the present disclosure will be described in detail below:
[0037] The collision detection assembly 10 is used for detecting the collision of the cleaning device 100 and the obstacle, when the collision detection assembly 10 detects the collision of the cleaning device 100 and the obstacle, a collision signal is transmitted to the control module of the cleaning device 100, and the control module replans the walking route of the cleaning device 100 according to the collision signal.
[0038] The first detection piece 11 is used for detecting the collision of the cleaning device 100 in a first direction, and the second detection piece 12 is used for detecting the collision of the cleaning device 100 in a second direction. The first direction and the second direction are perpendicular, for example, the first direction can be a horizontal direction, and the second direction can be a vertical direction. The first detection piece 11 detects the collision of the cleaning device 100 with the obstacle in front or side front during walking, and the second detection piece 12 detects the collision of the top of the cleaning device 100 during walking.
[0039] It can be understood that in the present disclosure, the first direction and the second direction are not limited to the horizontal direction and the vertical direction, for example, the first direction can be the vertical direction, and the second direction can be the horizontal direction. Or the first direction can form a preset angle with the horizontal direction, etc.
[0040] The first detection member 11 and the second detection member 12 can be arranged on the device body 20 of the cleaning device 100, and the device body 20 of the cleaning device 100 can move. The first detection member 11 is arranged on the side surface of the device body 20, and the second detection member 12 is arranged on the top surface of the device body 20. The first detection member 11 and the second detection member 12 have a gap therebetween, and the electrical connection member 13 is arranged between the first detection member 11 and the second detection member 12. The second detection member 12 is arranged on the top surface of the device body 20, so that the cleaning device 100 can avoid being stuck by low obstacles, such as the bottom of a sofa or the bottom of a bed.
[0041] For example, the first detection member 11 can be arranged on the side surface of the device body 20, and the second detection member 12 can be arranged above the first detection member 11. That is, the second detection member 12 is integrated on the first detection member 11 to improve the assembly efficiency of the two. The first detection member 11 can be arranged on the side surface of the front side of the device body 20, and correspondingly, the second detection member 12 can also be arranged on the side surface of the front side of the device body 20. When the first detection member 11 and / or the second detection member 12 detects an impact during the operation of the cleaning device 100, the cleaning device 100 can respond, and the cleaning device 100 can be controlled to stop moving forward, move backward, change direction to move in other directions, or stop moving, so as to prevent the cleaning device 100 from continuing to move forward and being stuck by obstacles, which has good practicability.
[0042] Alternatively, the first detection member can be arranged on the side surface of the device body 20, and the second detection member 12 can be arranged on the edge of the top surface of the device body 20. For example, the first detection member 11 can be arranged on the front side of the device body 20, and the second detection member 12 can be arranged on the edge of the front side of the top surface of the device body 20. When the first detection member 11 and / or the second detection member 12 detects an impact during the operation of the cleaning device 100, the cleaning device 100 can respond, and the cleaning device 100 can be controlled to stop moving forward, move backward, change direction to move in other directions, or stop moving, so as to prevent the cleaning device 100 from continuing to move forward and being stuck by obstacles, which has good practicability.
[0043] The first detection member protrudes from the front side of the device body 20, so that when an obstacle in front is encountered, the first detection member collides with the obstacle in front first. The second detection member 12 protrudes from the top surface of the device body 20, so that when an obstacle above is encountered, the second detection member 12 collides with the obstacle above first.
[0044] The first detection member 11 can include a collision buffer plate 111 and a collision sensing module. At least part of the collision buffer plate 111 is configured to be movable in a horizontal direction to detect the collision of the cleaning device 100 in the horizontal direction, and the collision sensing module is triggered in response to the movement of the collision buffer plate 111.
[0045] The collision buffer plate 111 is used to clean the collision between the cleaning device 100 and the surrounding objects during the movement, and is slidably installed on the edge of the front side of the device body 20, and is approximately 180° arc-shaped. The collision sensing module can be provided with two, which are oppositely arranged on the device body 20, and are symmetrically arranged or approximately symmetrically arranged. Each collision sensing module includes an elastic member and a contact switch, and the elastic member is connected with the collision buffer plate 111. When the collision buffer plate 111 encounters an obstacle, the collision buffer plate 111 slides close to the device body 20, and the elastic member deforms accordingly until the collision buffer plate 111 abuts on a certain contact switch on the device body 20. The contact switch sends a touch signal to the controller of the cleaning device 100, and the controller of the cleaning device 100 controls the cleaning device 100 to stop advancing, retreating or changing direction to drive or stop driving to prevent the cleaning device 100 from continuing to advance and being trapped by the obstacle. After the cleaning device 100 is released, the elastic member returns to the initial state, and the collision buffer plate 111 returns to the initial state, and the cleaning device 100 can operate normally.
[0046] Since the collision buffer plate 111 is approximately 180° arc-shaped, the first detection member 11 can not only detect the obstacle on the front side of the cleaning device 100, but also detect the obstacle on the lateral side of the cleaning device 100, which has good practicability.
[0047] The first detection member 11 is provided with a containing portion for containing the electric connecting member 13 and the second detection member 12. For example, the containing portion can be a groove or a recess on the first detection member 11, the electric connecting member 13 is arranged in the recess, and the second detection member 12 is at least partially located in the recess.
[0048] For example, as shown in FIG. 4, the first detection member 11 can include a collision buffer plate 111 and a support plate 112. The collision buffer plate 111 has a front surface and a rear surface, and the front surface of the collision buffer plate 111 can contact the obstacle when the cleaning device 100 moves. The support plate 112 is arranged on the rear surface of the collision buffer plate 111, the rear surface of the collision buffer plate 111 forms a second wall, and the support plate 112 forms a first wall.
[0049] The collision buffer plate 111 is in an arc shape, and the outer arc surface of the collision buffer plate 111 is a front surface, and the inner arc surface of the collision buffer plate 111 is a rear surface. The support plate 112 is also in an arc shape, and the structure of the support plate 112 matches the structure of the collision buffer plate 111. The support plate 112 and the collision buffer plate 111 can be an integral structure, for example, the support plate 112 and the collision buffer plate 111 can be formed by injection molding or bending, etc. Of course, the support plate 112 and the collision buffer plate 111 can also be a split structure, for example, the support plate 112 is connected to the collision buffer plate 111 by clamping, bonding or bolt connection, etc.
[0050] When the second detection piece 12 is arranged on the top of the first detection piece 11, in order to form a sunken accommodating portion on the top of the first detection piece 11, the top surface of the support plate 112 is lower than the bottom surface or the top surface of the collision buffer plate 111. For example, the top surface of the collision buffer plate 111 can be flush with the top surface of the device body 20, and the top surface of the support plate 112 is lower than the top surface of the device body 20.
[0051] The second detection piece 12 includes a pressure bearing buffer piece 121 and a pressure bearing sensing module 122, the pressure bearing buffer piece 121 at least partially overlaps the first detection piece 11 in the vertical direction (the projection of the pressure bearing buffer piece 121 on the first detection piece 11 at least partially overlaps the first detection piece 11), and the pressure bearing sensing module 122 is arranged between the first detection piece 11 and the pressure bearing buffer piece 121.
[0052] The pressure bearing buffer piece 121 can move relative to the first detection piece 11 in the second direction, and when the pressure bearing buffer piece 121 approaches the first detection piece 11, the pressure bearing sensing module 122 is triggered, and the pressure bearing sensing module 122 generates an induction signal, which is transmitted to the control module of the cleaning device 100 through the electrical connection piece 13.
[0053] Further, as shown in FIG. 5, the second detection piece 12 can further include a guide piece 124 and a reset piece 123, the guide piece 124 is used for guiding the movement of the pressure bearing buffer piece 121, and the reset piece 123 is used for resetting the pressure bearing buffer piece 121 when the external obstacle disappears.
[0054] The reset piece 123 is connected between the support plate 112 and the pressure bearing buffer piece 121. Under the condition that the pressure bearing buffer piece 121 contacts the obstacle, the pressure bearing buffer piece 121 moves towards the support plate 112 to compress the reset piece 123, and the pressure bearing buffer piece 121 triggers the pressure bearing sensing module 122. Under the condition that the pressure bearing buffer piece 121 and the obstacle are out of contact, the reset piece 123 restores the deformation, and the pressure bearing buffer piece 121 moves away from the support plate 112 to restore to the initial state.
[0055] The reset member 123 can be a spring, for example, and both ends of the spring can be connected to the support plate 112 and the pressure bearing buffer 121. The spring and the support plate 112 and the pressure bearing buffer 121 can be abutted or fixedly connected. A guide column can be provided on the pressure bearing buffer 121 or the support plate 112, and the spring is arranged on the guide column.
[0056] The pressure bearing buffer 121 is provided with a guide member 124, and the support plate 112 is provided with a guide portion matched with the guide member 124. The guide member 124 can move relative to the guide portion in the second direction, and the guide member 124 and the guide portion are matched to enable the pressure bearing buffer 121 to move in the second direction.
[0057] The guide member 124 can be in a columnar structure, and the guide portion can be a guide hole. The guide member 124 is inserted into the guide hole. When the pressure bearing buffer 121 contacts an obstacle, the pressure bearing buffer 121 moves towards the support plate 112, and the guide member 124 and the guide portion are inserted to guide the movement of the pressure bearing buffer 121.
[0058] To prevent the pressure bearing buffer 121 and the first detection member 11 from being loosened, the size of the guide member 124 can be gradually changed, and the size of the guide portion can also be gradually changed. The cross-sectional area of the guide member 124 gradually increases in a direction away from the pressure bearing buffer 121, and the cross-sectional area of the guide portion gradually increases in a direction away from the pressure bearing buffer 121. For example, the guide member 124 can be a cone, and a positioning column can be provided at the bottom of the pressure bearing buffer 121. The pressure bearing buffer 121 is sleeved on the positioning column and fixed on the positioning column by a screw or the like. In other embodiments, the guide member 124 can also be integrally formed at the bottom of the pressure bearing buffer 121, which is not limited here.
[0059] The second detection member 12 includes a plurality of pressure sensing modules 122, and the plurality of pressure sensing modules 122 are spaced apart on the electrical connector 13. The plurality of pressure sensing modules 122 can be uniformly distributed on the electrical connector 13, for example, the electrical connector 13 is in an arc shape. The plurality of pressure sensing modules 122 are uniformly arranged along the circumference of the arc-shaped electrical connector 13.
[0060] The pressure sensing module 122 can be a pressure switch, which is triggered when the pressure bearing buffer 121 moves in the second direction beyond a preset distance. The pressure switch can include a moving part and a static part, the static part is fixedly connected with the electrical connector 13, the moving part is connected with the static part, and the moving part can move relative to the static part. When the pressure bearing buffer 121 moves, the pressure bearing buffer 121 pushes the moving part to move relative to the static part, thereby triggering the pressure switch.
[0061] It can be understood that in the embodiments of the present disclosure, the pressure sensing module 122 is not limited to a pressure switch, and the pressure sensing module 122 can also be a pressure sensor or a distance sensor.
[0062] The electrical connector 13 is used to electrically connect a plurality of pressure sensing modules 122 and transmit the sensing signals generated by the pressure sensing modules 122 in response to the movement of the pressure buffering member 121. In some embodiments, the electrical connector 13 can be a flexible printed circuit (FPC), and of course the electrical connector 13 can also be a printed circuit board or a conductive wire array.
[0063] The electrical connector 13 includes a plurality of lug portions 132 and a main body portion 131, the pressure sensing modules 122 are connected to the lug portions 132, and the main body portion 131 connects the plurality of lug portions 132. Adjacent two lug portions 132 among the plurality of lug portions 132 have a gap, and the gap between the adjacent lug portions 132 is used to arrange a guide 124 or the like, avoiding the need for the guide 124 or the like to pass through the electrical connector 13, causing the electrical connector 13 to short circuit or open circuit, and the like. And the gap between the adjacent lug portions 132 facilitates the bending of the electrical connector 13.
[0064] The first detection member 11 is provided with a receiving portion, the receiving portion has a first wall and a second wall which are not coplanar, the first wall is opposite to the pressure buffering member 121, the lug portion 132 is arranged on the first wall, and the main body portion 131 is arranged on the second wall. By arranging the main body portion 131 on the second wall and the lug portion 132 on the first wall, the gap between the first detection member 11 and the second detection member 12 is used to accommodate the electrical connector 13, improving the space utilization and the convenience of arrangement, and solving the problems of large space occupation and difficult assembly of the collision detection assembly.
[0065] The first wall is parallel to the horizontal plane, and the second wall is a vertical arc surface. The main body portion 131 and the lug portion 132 are both thin plate structures, the lug portion 132 is arranged close to the first wall, and the main body portion 131 is arranged close to the second wall. For example, the main body portion 131 has a long rectangular structure, the main body portion 131 is bent to be arc-shaped according to the shape of the first detection member 11, and the main body portion 131 is connected to the second wall by adhesion or bolt connection or the like. The lug portion 132 can have a rectangular or approximately rectangular shape, and the lug portion 132 is connected to the first wall by adhesion or bolt connection or the like.
[0066] In some embodiments, the rear surface of the collision buffering plate 111 forms the second wall, and the support plate 112 forms the first wall. That is, the main body portion 131 of the electrical connector 13 is arranged on the rear surface of the collision buffering plate 111, the lug portion 132 is arranged on the top surface of the support plate 112, and the gap between the adjacent lugs is used to avoid other components on the support plate 112.
[0067] In some embodiments, as shown in FIG. 6, the electrical connecting member 13 includes a first conductive segment 301 and a second conductive segment 302, the first conductive segment 301 and the second conductive segment 302 are connected, a projection of the first conductive segment 301 on the first detecting member 11 forms a first projection area, the first projection area is provided with at least one pressure sensing module 122, a projection of the second conductive segment 302 on the first detecting member 11 forms a second projection area, the second projection area is provided with at least one pressure sensing module 122. By setting the conductive member as a two-segment structure, the installation of the conductive member is facilitated.
[0068] In some embodiments, the first conductive segment 301 can be a first flexible circuit board, and the second conductive segment 302 can be a second flexible circuit board. The first flexible circuit board is provided with a conductive trace, and the conductive trace is connected with the pressure sensing module 122 arranged on the first flexible circuit board.

[0069] Further, the collision detection assembly 10 can further include a connecting seat 14, the connecting seat 14 is arranged on a side of the electrical connecting member 13 away from the pressure buffering member 121, and the connecting seat 14 is connected with the first conductive segment 301 and the second conductive segment 302 respectively.
[0070] The connecting seat 14 has a conductive structure, the conductive structure on the connecting seat 14 is electrically connected with the electrical connecting member 13, and the connecting seat 14 is used for connecting a signal transmission circuit, which can be connected with a control module of the cleaning device 100.
