DETAILED DESCRIPTION

[0035] It should be noted that, unless there is a conflict, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of this application and should not be regarded as an improper restriction on this application.

[0036] In the description of the application embodiment, for the convenience of explanation, as shown in FIG. Figure 3 、 Figure 4 、 Figure 5 and Figure 8 , the direction of arrow X is the “first direction”; Figure 4 and Figure 8 As shown, the direction of arrow Y is the "second direction"; Figure 3 、 Figure 6 、 Figures 8 to 10 As shown, the direction of arrow Z is the "third direction" and the "vertical direction". It should be understood that these directional terms are only used to facilitate the description of this application and simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting this application.

[0037] An embodiment of the present application provides a detection component 10 for use in a cleaning device. The detection component 10 can be used to detect obstacle information in the direction of travel of the cleaning device during movement, so that the cleaning device can execute corresponding avoidance strategies based on the obstacle information.

[0038] See Figures 1 to 4 The detection assembly 10 in the embodiment of the present application includes a detection device 11, a mounting member 12, an elastic member 13 and a sensing device 14.

[0039] The detection device 11 includes a moving part.

[0040] The moving portion can move relative to the mounting member 12 along a first direction.

[0041] The sensing device 14 has a sensing area. One of the moving portion and the mounting member 12 is provided with the sensing device 14 , and the other has a triggering area. The sensing area and the triggering area are opposite to each other along a first direction.

[0042] The elastic member 13 is located between the moving portion and the mounting member 12 and can elastically expand and contract along a first direction.

[0043] The detection device 11 is used to obtain obstacle information. The specific type of the detection device 11 can be a camera, a millimeter wave radar, a laser radar, etc.

[0044] The mounting member 12 provides a mounting location for the detection device 11 to be arranged in the cleaning device.

[0045] When the detection device 11 collides with an external object, the external object may come into contact with the moving portion, causing the moving portion to move relative to the mounting member 12 along the first direction under the action of the collision force.

[0046] The moving part may be the entire detection device 11 or a part of the detection device 11 .

[0047] The sensing area is used to determine whether a collision has occurred with the detection device 11. When a collision is determined to have occurred, the sensing device 14 can send a collision signal. After receiving the signal, the control device of the cleaning device executes a corresponding strategy to reduce the risk of damage to the detection device 11.

[0048] The triggering area is the portion of the structure of one of the moving portion and the mounting member 12 where the sensing device 14 is not provided.

[0049] The elastic member 13 can elastically expand and contract along the first direction, so that the moving portion needs to overcome the elastic force of the elastic member 13 before it can move along the first direction toward the sensing area until it contacts the sensing area.

[0050] The detection component 10 in the embodiment of the present application triggers the sensing device 14 through the relative movement of the moving part and the mounting part 12, which is conducive to determining whether the detection device 11 has been subjected to a collision; the elastic force applied to the moving part and the mounting part 12 by the elastic part 13 is conducive to reducing the risk of false triggering due to contact between the trigger area and the sensing area due to the vibration of the cleaning equipment itself, acceleration and deceleration changes, etc.; on the other hand, it is convenient for the position of the moving part to automatically recover after the detection device 11 is separated from the object that has collided, so as to facilitate timely judgment of subsequent collisions of the detection device 11.

[0051] In some embodiments, see Figure 5 At least one of the detection device 11 and the sensing device 14 is electrically connected to the power supply 15. The power supply 15 can supply power to at least one of the detection device 11 and the sensing device 14 so that both can work normally.

[0052] In some embodiments, the detection assembly 10 includes a trigger state and a standby state; in the standby state, the trigger area and the sensing area are spaced apart along the first direction; in the trigger state, the trigger area and the sensing area abut along the first direction, and the elastic member 13 is in a stretched state or a compressed state.

[0053] In the standby state, there is a gap between the trigger area and the sensing area, indicating that the outside world does not apply a force to the moving part or the applied force is small, which indirectly indicates that the detection device 11 has not collided.

[0054] In the triggered state, the external force applied to the moving part is sufficient to overcome the elastic force of the elastic member 13 and make the trigger area contact with the sensing area, indicating that the external force applied to the moving part is large, and it can be considered that the detection device 11 has collided.

[0055] It can be understood that, in the triggered state, the elastic member 13 is in a stretched state or a compressed state, so that the elastic member 13 stores elastic potential energy.

[0056] After the detection device 11 is separated from the object with which it collides, the detection device 11 is no longer squeezed by the object with which it collides, the elastic potential energy of the elastic member 13 is released, and the elastic member 13 applies a force to the moving part, thereby pushing the trigger area away from the sensing area, so that the sensing device 14 re-determines that the detection device 11 has not collided.

[0057] It can be understood that the first direction is the forward direction of the cleaning device.

[0058] In some embodiments, in the standby state, the elastic member 13 is in a stretched state or a compressed state. This helps to keep the position of the detection device 11 relatively stable in the standby state, and helps to improve the accuracy of the detection device 11 in detecting obstacles.

[0059] The specific type of the power source 15 can be a silver-zinc battery, a lithium battery, etc.

[0060] The sensing device 14 may be a force sensor to convert the force signal received by the sensing area into an electrical signal.

[0061] In some embodiments, see 3. Figure 4 and Figure 8 The mounting member 12 is provided with a mounting cavity 12a, one side of the mounting cavity 12a is open, a portion of the detection device 11 is located in the mounting cavity 12a, at least a portion of the sensing device 14 and at least a portion of the elastic member 13 are both located in the mounting cavity 12a.

[0062] It is understandable that a portion of the detection device 11 is located outside the installation cavity 12a so that the detection device 11 can detect external obstacles and reduce the obstruction of the detection field of the detection device 11 by the inner wall of the installation cavity 12a.

[0063] In this way, the inner wall of the installation cavity 12 a can provide a certain degree of protection for the sensing device 14 and the elastic member 13 , thereby reducing the probability of the sensing device 14 and the elastic member 13 being damaged by collision.

[0064] It is understandable that the detection device 11 includes various types of electronic components.

[0065] In some embodiments, see Figure 3 and Figure 4 The detection device 11 includes a cover 111 and a device body 112. The cover 111 is provided with an installation space 111a. At least a portion of the device body 112 is located in the installation space 111a. One of the trigger area and the sensing device 14 is provided in the cover 111, and the other is provided on the inner wall of the installation cavity 12a.

[0066] The device body 112 refers to the portion of the detection device 11 used to implement the detection function, which includes various types of electronic components.

[0067] The cover 111 provides a certain degree of protection to the device body 112, which is beneficial in that when the detection device 11 collides, the cover 111 replaces the device body 112 in the probability of collision, thereby reducing the probability that the detection device 11 cannot realize its detection function due to collision.

[0068] In some embodiments where the detection device 11 is a laser radar, at least a portion of the housing 111 is light-transmissive so that laser light can pass through the housing 111 .

[0069] In some embodiments, see Figure 3The mounting member 12 is provided with a mounting cavity 12a, one side of the mounting cavity 12a is open, one side of the mounting space 111a is open to communicate with the mounting cavity 12a, a portion of the cover 111 is located outside the mounting cavity 12a, and the other portion is located inside the mounting cavity 12a.

[0070] This helps to completely cover the mounting member 12 and the cover shell 111 on the outside of the device body 112, further reducing the probability of collision between external objects and the device body 112, thereby further improving the protection effect of the device body 112.

[0071] In some embodiments, see Figure 3 and Figure 4 The mounting member 12 is fixed to the device body 112 , the cover 111 forms the moving portion, the elastic member 13 is located between the mounting member 12 and the cover 111 , and the inner wall of the mounting space 111 a is spaced apart from the device body 112 .

[0072] That is, the device body 112 will not move relative to the mounting member 12 , and only the cover 111 can move relative to the mounting member 12 after the collision.

[0073] In this way, when the cover 111 collides, the collision force applied thereto will not be directly transmitted to the device body 112 , thereby reducing the probability of the device body 112 being damaged by the force.

[0074] It can be understood that, in the standby state, the size of the gap between the inner wall of the installation space 111a and the device body 112 along the first direction is greater than the size of the gap between the trigger area and the sensing area along the first direction, so that in the trigger state, the cover 111 and the device body 112 still maintain a gap along the first direction.

[0075] In some embodiments where a power source 15 is provided, see Figure 3 and Figure 5 The power supply 15, the device body 112 and the induction device 14 are all fixed to the mounting member 12 to reduce the probability of the electrical connection between the power supply 15 and the two being interrupted due to relative movement.

[0076] In some embodiments, the top side of the installation cavity 12 a is open in the vertical direction, and the bottom wall of the installation cavity 12 a is used to support the device body 112 .

[0077] The method of fixing the device body 112 to the mounting member 12 is not limited. For example, the device body 112 is provided with a threaded hole, and the mounting member 12 is provided with a through hole. A screw passes through the through hole and cooperates with the thread in the threaded hole to achieve a threaded connection between the two, so that the device body 112 can be subsequently disassembled and assembled for maintenance and replacement.

[0078] In some embodiments, see Figure 3The detection assembly 10 also includes a stopper 16. One of the mounting member 12 and the detection device 11 is provided with a stopper 16, and the other has a stop surface 12b. In the standby state, the stopper 16 is spaced from the stop surface 12b along the first direction; in the triggered state, the stopper 16 abuts against the stop surface 12b along the first direction.

[0079] By abutting the stop member 16 and the stop surface 12b in the triggered state, a limiting effect on the movement of the moving part along the first direction is achieved, reducing the probability of damage to the sensing device 14 due to excessive force along the first direction between the moving part and the sensing device 14, which is beneficial to extending the service life of the sensing device 14.

[0080] The number of stoppers 16 can be one or more; the number of stop surfaces 12b can be one or more. One stopper 16 can be matched with one stop surface 12b in a one-to-one correspondence; one stopper 16 can be matched with multiple stop surfaces 12b; or multiple stoppers 16 can be matched with one stop surface 12b.

[0081] The specific method of forming the stop surface 12b is not limited.

[0082] For example, see Figures 3 to 5 、 Figure 8 One of the mounting member 12 and the detection device 11 is provided with a stop hole 12c, the extension direction of the stop hole 12c intersects with the first direction, at least part of the stop member 16 is embedded in the stop hole 12c along the extension direction of the stop hole 12c and is spaced apart from the inner wall of the stop hole 12c along the first direction, and a stop surface 12b is formed on the inner wall of one side of the stop hole 12c along the first direction.

[0083] It can be understood that the stop hole 12c is open along at least one side of its extension direction, so that the stop member 16 is embedded in the stop hole 12c through the open position of the stop hole 12c.

[0084] The inner wall of the stop hole 12c can constrain the movement of the stop member 16 in directions other than the first direction, which is conducive to guiding the stop member 16 along the first direction until it contacts the stop surface 12b through the inner wall of the stop hole 12c.

[0085] In some embodiments, see Figure 3 and Figure 5 In the standby state, the stopper 16 abuts against the inner wall of the stopper hole 12c on one side along the first direction.

[0086] That is, both sides of the stopping hole 12c along the first direction are closed ends, and the inner wall of one side forms a stopping surface 12b.

[0087] In this way, the travel of the stopper 16 along the first direction is limited, thereby limiting the travel of the moving portion relative to the mounting portion, which is beneficial for the elastic member 13 to be in a stretched state or a compressed state in the standby state.

[0088] In some embodiments, see Figure 3 and Figure 8 The stop member 16 includes a first stop member 161, and the stop hole 12c includes a first stop hole 12d. The first stop member 161 and the first stop hole 12d both extend along the second direction, and the first direction intersects with the second direction. At least a portion of the first stop member 161 is disposed in the first stop hole 12d. The first stop member 161 and the first stop hole 12d are rotationally engaged and the rotation axis extends along the second direction.

[0089] In this way, at least a portion of the detection device 11 can rotate relative to the mounting member 12, thereby facilitating maintenance of the detection device 11 when the detection assembly 10 is disassembled, thereby improving the convenience of maintenance.

[0090] In some embodiments, the first direction and the second direction are perpendicular to each other, so as to reduce the probability of the first stopping member 161 escaping from the first stopping hole 12d when the first stopping member 161 moves relative to the first stopping hole 12d along the first direction.

[0091] In some embodiments, see Figure 4 The first stop hole 12d is a through hole. On the one hand, it is beneficial to increase the size of the part of the first stop member 161 in the first stop hole 12d along its extension direction, thereby reducing the probability of the first stop member 161 escaping from the first stop hole 12d; on the other hand, it is also convenient for cleaning the first stop hole 12d, thereby reducing the probability of foreign matter entering the first stop hole 12d during the cleaning process of the cleaning equipment and affecting the movement of the first stop member 161.

[0092] In some embodiments having a housing 111 and a device body 112, see Figure 3 and Figure 8 The cover 111 is provided with an installation space 111a, which is open on one side along the third direction and faces the mounting member 12. At least part of the device body 112 is located in the installation space 111a and is fixed to the mounting member 12. The cover 111 forms a moving portion, and one of the first stop member 161 and the first stop hole 12d is provided on the cover 111, and the other is provided on the mounting member 12. The first direction, the second direction and the third direction intersect with each other.

[0093] In this way, the cover shell 111 can be rotated relative to the mounting part 12. Without separating the mounting part 12 and the device body, the cover shell 111 can be rotated to a suitable position relative to the mounting part 12, so that the device body is separated from the installation space 111a and exposed to the outside, so as to facilitate the inspection and maintenance of the device body, which is conducive to simplifying the inspection steps and improving work efficiency.

[0094] In some embodiments, the first direction, the second direction, and the third direction are perpendicular to each other, thereby reducing the probability of the first stopper 161 coming out of the first stopper hole 12d during the rotation of the cover 111 and the movement of the cover 111 relative to the mounting member 12 along the first direction.

[0095] In some embodiments, see Figure 8 , the first stopper 161 is located on one side of the detection device 11 along the first direction, and the sensing device 14 is located on the other side.

[0096] This helps reduce the probability of the first stopper 161 rotating relative to the first stopper hole 12d and moving along the first direction interfering with the sensing device 14, and helps reduce the size of the detection assembly 10 perpendicular to the first direction.

[0097] In some embodiments, see Figure 8 , the first stopper 161 is located on one side of the detection device 11 along the first direction, and the elastic member 13 is located on the other side.

[0098] This helps reduce the probability that the first stopper 161's rotation relative to the first stopper hole 12d and its movement along the first direction interfere with the expansion and contraction of the elastic member 13, and helps reduce the dimension of the detection assembly 10 perpendicular to the first direction.

[0099] The specific shape of the first stop hole 12d is not limited. Figure 3 The first stop hole 12d is a waist-shaped hole, and the long axis direction of the first stop hole 12d is the first direction.

[0100] In some embodiments, see Figure 3 and Figure 5 The stop member 16 includes a second stop member 162, the stop hole 12c includes a second stop hole 12e, the mounting member 12 is provided with a mounting cavity 12a, one side of the mounting cavity 12a along the third direction is open, the first direction intersects with the third direction, a portion of the detection device 11 is located in the mounting cavity 12a, the second stop member 162 and the second stop hole 12e both extend along the third direction, the second stop hole 12e is connected to the mounting cavity 12a, and at least a portion of the second stop member 162 is passed through the second stop hole 12e.

[0101] During the process of installing the detection device 11 into the installation cavity 12a through the open position of the installation cavity 12a along the third direction, the purpose of at least partially inserting the second stop member 162 into the second stop hole 12e can be achieved simultaneously, which is conducive to simplifying the assembly steps and improving work efficiency.

[0102] Understandably, see Figure 8 The second stop hole 12e is located on a side of the mounting cavity 12a away from its open position along the third direction.

[0103] In some embodiments, see Figure 8 The second stop hole 12e penetrates the mounting member 12 along the third direction. On the one hand, it is beneficial to increase the size of the portion of the second stop member 162 in the second stop hole 12e along the third direction, thereby reducing the probability of the second stop member 162 escaping from the second stop hole 12e. On the other hand, it also reduces the probability of foreign matter accumulating in the second stop hole 12e during the cleaning process of the cleaning equipment and affecting the movement of the second stop member 162.

[0104] In some embodiments, see Figure 6 The second stop member 162 is provided on the side of the detection device 11 close to the mounting member 12 along the third direction, the second stop hole 12e penetrates the mounting member 12 along the third direction, and the end of the second stop member 162 away from the detection device 11 along the third direction passes through the second stop hole 12e from the mounting cavity 12a and extends out, and the extended part is provided with a limiting protrusion 1621, and a part of the mounting member 12 is located between the detection device 11 and the limiting protrusion 1621 along the third direction.

[0105] A portion of the second stopper 162 is located in the mounting cavity 12 a , a portion is located in the second stopper hole 12 e , and another portion is located outside the mounting member 12 .

[0106] In this way, through the cooperation between the limiting protrusion 1621 and the detection device 11, the relative position between the detection device 11 and the mounting member 12 along the third direction is limited, thereby reducing the probability of the second stop member 162 escaping from the second stop hole 12e due to vibration, collision, etc.

[0107] The specific method of forming the limiting protrusion 1621 is not limited.

[0108] For example, in the embodiment where the second stop hole 12e passes through the mounting member 12, see Figure 6 and Figure 8The detection device 11 includes a threaded column, which extends along the third direction. A mounting threaded hole extending along the third direction is provided in the threaded column. A portion of the threaded column is embedded in the second stop hole 12e from one side of the second stop hole 12e along the third direction. The screw is inserted into the threaded mounting hole from one side of the second stop hole 12e along the third direction, and the nut of the screw forms a limiting protrusion 1621.

[0109] In this way, the limiting protrusion 1621 will not interfere with the assembly between the second stopping member 162 and the second stopping hole 12e.

[0110] It is understandable that the collision direction received by the detection device 11 may be parallel to the first direction, or may form a certain angle with the first direction.

[0111] In some embodiments, see Figure 5 and Figure 7 In the projection plane perpendicular to the third direction, the size of the projection area of ​​the second stop hole 12e along the second direction gradually increases from the first end 12f to the second end 12g along the first direction. The first direction, the second direction and the third direction are perpendicular to each other. The inner wall of the second end 12g of the second stop hole 12e forms a stop surface 12b. In the standby state, the inner walls on both sides of the second stop hole 12e along the second direction are respectively located on one side of the second stop member 162 along the second direction.

[0112] It is understood that in the triggered state, the second stopper 162 abuts against the inner wall of the second end 12g of the second stopper hole 12e. In the event of a collision of the detection device 11, the second stopper 162 moves from the first end 12f to the second end 12g of the second stopper hole 12e.

[0113] When the collision direction forms a certain angle with the first direction, the collision force can be decomposed into a force component along the first direction and a force component perpendicular to the first direction. On the one hand, under the action of the force component along the first direction, the second stop member 162 can move relative to the second stop hole 12e in the first direction. On the other hand, because the size of the second stop hole 12e gradually increases along the second direction from the first end 12f to the second end 12g, this facilitates the second stop member 162 to move directly in the second direction under the action of the force component perpendicular to the first direction.

[0114] In this way, the probability that the second stop member 162 abuts against the inner wall of the second stop hole 12e along the second direction and increases the friction between the two during the process of the second stop member 162 moving along the first direction relative to the second stop hole 12e is reduced, thereby facilitating the second stop member 162 to move to the second end 12g more smoothly and reducing the probability of the second stop member 162 getting stuck during the movement.

[0115] In the projection plane perpendicular to the third direction, the extension directions of the projections of the inner walls of the second stop hole 12e on both sides along the second direction form a certain angle with the first direction, and the two are located on different sides of the second stop member 162 along the second direction so as to adapt to the different impact directions received by the detection device 11.

[0116] In some embodiments, the first direction and the second direction are two directions parallel to each other in the horizontal direction, the third direction is a vertical direction, and the mounting member 12 contacts the detection device 11 along the third direction.

[0117] In this way, when the detection device 11 is hit in the horizontal direction, the moving part can move in the first direction and perpendicular to the first direction relative to the mounting member 12; when the detection device 11 is hit in the direction inclined to the horizontal, the moving part can move in the first direction relative to the mounting member 12, and the component force in the vertical direction can be transmitted to the mounting member 12, thereby reducing the probability of the detection device 11 being damaged by bearing the component force in the vertical direction.

[0118] In some embodiments, see Figure 7 In the projection plane perpendicular to the third direction, the projection of the inner wall of the first end 12f and the projection of the inner wall of the second end 12g of the second stop hole 12e are both arc-shaped, and the line 12h connecting the centers of the two circles extends along the first direction, and the projections of the inner walls on both sides of the second stop hole 12e along the second direction are symmetrical about the line 12h.

[0119] The projections of the inner walls of the first end 12f and the second end 12g are both arc-shaped, which helps to reduce the risk of stress concentration and damage to the inner wall of the second stop hole 12e when the second stop member 162 abuts against the inner wall of the second stop hole 12e.

[0120] The inner walls on both sides of the second stop hole 12e are symmetrically arranged along the second direction, so that when the second stop member 162 moves from the first end 12f to the second end 12g, the moving distances in the two directions along the second direction are the same, so as to better adapt to the different impact directions received by the detection device 11.

[0121] It can be understood that the inner walls on both sides of the second stop hole 12e along the second direction are tangent to the inner wall of the first end 12f and the inner wall of the second end 12g respectively, so as to improve the smoothness of the movement of the second stop member 162 in the second stop hole 12e.

[0122] In some embodiments having a housing 111 and a device body 112, see Figure 6 and Figure 8The cover 111 is provided with an installation space 111a, and the installation space 111a is open on one side along the third direction to communicate with the installation cavity 12a. At least part of the device body 112 is located in the installation space 111a and is fixed to the mounting member 12. The cover 111 forms a moving part, and one of the second stop member 162 and the second stop hole 12e is provided on the cover 111, and the other is provided on the mounting member 12.

[0123] In this way, through the cooperation of the second stop member 162 and the second stop hole 12e, the movement stroke of the cover 111 relative to the mounting member 12 along the first direction can be limited; in the process of assembling the detection component 10, the device body 112 and the mounting member 12 can be fixed first, and then the cover 111 can be covered on the outside of the device body 112 along the third direction and the second stop member 162 can be cooperated with the second stop hole 12e.

[0124] In some embodiments, see Figure 8 A support rib 121 is provided on the inner wall of the installation cavity 12a along the third direction away from its open position. The support rib 121 protrudes from the inner wall of the installation cavity 12a along the third direction. The support rib 121 is used to abut against the cover shell 111 along the third direction.

[0125] In this way, the cover 111 can be limited along the third direction by the support ribs 121 and the limiting protrusions 1621, thereby reducing the risk of the detection assembly 10 being displaced along the third direction under the action of external forces.

[0126] The specific number of the support rib 121 is not limited and can be one; Figure 8 , or multiple.

[0127] In some embodiments, see Figure 8 The support rib 121 is provided with a limiting groove 121a. The limiting groove 121a is open along the third direction toward one side of the open position of the installation cavity 12a. A portion of the cover 111 can be inserted into the limiting groove 121a and abut against the inner wall of the support rib 121 along the third direction. At least one side of the limiting groove 121a along the first direction is a closed end, so that the inner wall of the closed end can engage with the cover 111 in the first direction. The inner wall of the limiting groove 121a along the first direction limits the movement of the cover 111 in the first direction.

[0128] The specific structure of the elastic member 13 is not limited.

[0129] For example, see Figure 4 and Figure 8 The elastic member 13 is a torsion spring, and the two force-bearing ends of the torsion spring are spaced apart along the first direction, one force-bearing end is used to contact the mounting member 12, and the other force-bearing end is used to contact the moving part.

[0130] The specific number of the elastic member 13 can be one or more.

[0131] In some embodiments where the elastic member 13 is a torsion spring, see Figure 8 A mounting column 122 is provided on the inner wall of the mounting cavity 12a on the side away from its open position along the third direction. The mounting column 122 extends along the third direction and passes through the inner wall of the torsion spring. In this way, the mounting column 122 limits the elastic member 13 along the first direction and the second direction.

[0132] The present application also provides a cleaning device, see Figure 9 and Figure 10 The cleaning device includes a body 20 and a detection assembly 10 of any one of the aforementioned embodiments. The detection assembly 10 is arranged on the body 20 so that when the body 20 moves, the detection device 11 can be used to detect obstacles on the moving path of the body 20.

[0133] In some embodiments, the cleaning device further includes a power device connected to the body 20 for driving the body 20 to move.

[0134] In some embodiments, see Figure 9 and Figure 10 The detection device 11 is located on the top of the fuselage 20 so that the detection device 11 can have a wider detection range.

[0135] In some embodiments, see Figure 9 The cleaning device also includes a driving device 30. The body 20 is provided with an accommodating space 20a. The top side of the accommodating space 20a is open. The driving device 30 and the detection assembly 10 are arranged in the accommodating space 20a. The detection device 11 is arranged on the top of the mounting member 12. The driving device 30 is driven and connected to the detection device 11. In the standby state, the driving device 30 drives at least a portion of the detection device 11 to extend out of the accommodating space 20a. In the triggered state, the driving device 30 drives at least a portion of the detection device 11 to retract into the accommodating space 20a.

[0136] The driving device 30 is used to drive the detecting device 11 to move in the vertical direction. The detecting device 11 can extend out of or retract into the accommodating space 20a through the opening on the top side of the accommodating space 20a.

[0137] In the standby state, at least part of the detection device 11 is located outside the accommodating space 20a, so that the detection device 11 has a wider detection range; in the triggered state, the detection device 11 retracts into the accommodating space 20a, thereby realizing the protection of the fuselage 20 on the detection device 11, and also enabling the detection device 11 to avoid external objects, thereby reducing the risk of damage caused by further contact between the detection device 11 and external objects.

[0138] The driving device 30 is connected to the detection device 11 in a driving manner. The driving device 30 may be directly connected to the detection device 11 to drive the detection device 11 to move; or the mounting member 12 may be connected to the detection device 11, and the driving device 30 drives the detection device 11 to move by driving the mounting member 12.
