Detection components and cleaning equipment Cross-references to related applications

[0001] This application claims priority to Chinese patent applications Nos. 202411464941.0 and 202422531621.4, filed on October 18, 2024, the contents of which are incorporated herein by reference in their entirety as part of this disclosure. Technical Field

[0002] This disclosure relates to the field of cleaning equipment technology, specifically to a detection component and a cleaning device. Background Technology

[0003] With the continuous improvement of living conditions and technological level, cleaning equipment, represented by robotic vacuum cleaners, has gradually begun to replace manual cleaning and has become widely used in life and work.

[0004] As the cleaning equipment moves, it needs to obtain information about obstacles in its path through its installed detection devices in order to avoid obstacles in time and reduce the risk of collision between the robot vacuum and obstacles.

[0005] The detection device is located on top of the cleaning equipment. If an obstacle is just higher than the main body of the cleaning equipment but lower than the highest point of the detection device, the main body of the detection device will not be able to detect the existence of the obstacle, making it easy for the detection device to collide with the obstacle and cause damage to the detection device.

[0006] Therefore, it is necessary to obtain information about collisions with the detection device in a timely manner so that the cleaning equipment can take appropriate countermeasures and reduce the damage to the detection device. Summary of the Invention

Detailed Implementation

[0045] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this disclosure can be combined with each other, and the detailed descriptions in the specific embodiments should be understood as explanations of the purpose of this disclosure and should not be regarded as undue limitations on this disclosure.

[0046] In the description of the embodiments of this disclosure, for ease of explanation, as shown in Figures 3, 4, 5, and 8, the direction of arrow X is designated as the "first direction"; as shown in Figures 4 and 8, the direction of arrow Y is designated as the "second direction"; and as shown in Figures 3, 6, 8 to 10, the direction of arrow Z is designated as the "third direction" and the "vertical direction". It should be understood that these directional terms are for the convenience of describing this disclosure and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure.

[0047] This disclosure provides a detection component 10 for use in a cleaning device. The detection component 10 can detect obstacle information in the direction of travel of the cleaning device during its movement, so that the cleaning device can execute corresponding avoidance strategies based on the obstacle information.

[0048] Referring to Figures 1 to 4, the detection component 10 in this embodiment includes a detection device 11, a mounting component 12, an elastic component 13, and a sensing device 14.

[0049] The detection device 11 includes a moving part.

[0050] The movable part is capable of moving relative to the mounting member 12 in a first direction.

[0051] The sensing device 14 is provided with a sensing area. One of the moving part and the mounting part 12 is provided with the sensing device 14, and the other has a trigger area. The sensing area and the trigger area are opposite to each other in a first direction.

[0052] The elastic element 13 is located between the moving part and the mounting part 12 and can elastically extend and retract along the first direction.

[0053] The detection component 10 includes a triggered state and a standby state; in the standby state, the triggered area and the sensing area are spaced apart along a first direction; in the triggered state, the triggered area and the sensing area abut against each other along the first direction, and the elastic member 13 is in a stretched state or a compressed state.

[0054] The detection device 11 is used to acquire obstacle information. The specific type of the detection device 11 can be a camera, millimeter-wave radar, lidar, etc.

[0055] Mounting component 12 provides a mounting location for the detection device 11 in the cleaning equipment.

[0056] When the detection device 11 collides with an external object, the external object can come into contact with the moving part, causing the moving part to move relative to the mounting member 12 in the first direction under the action of the collision force.

[0057] The moving part can be the entire detection device 11 or a part of the detection device 11.

[0058] The sensing area is used to determine if a collision has occurred to the detection device 11. Upon determining that a collision has occurred, the sensing device 14 can emit a collision signal. After receiving this signal, the control device of the cleaning equipment executes a corresponding strategy to reduce the risk of damage to the detection device 11.

[0059] The trigger area is the part of the structure of the moving part and the mounting part 12 that does not have a sensing device 14.

[0060] The elastic element 13 can elastically expand and contract along the first direction, so that the moving part needs to overcome the elastic force of the elastic element 13 in order to move along the first direction toward the sensing area until it comes into contact with it.

[0061] In standby mode, the interval between the trigger area and the sensing area indicates that no force is applied to the moving part from the outside or the applied force is small, which indirectly indicates that the detection device 11 has not been collided with.

[0062] In the triggered state, the force applied to the moving part by the outside is sufficient to overcome the elastic force of the elastic member 13 and make the trigger area contact the sensing area, indicating that the force applied to the moving part by the outside is large, and it can be considered that the detection device 11 has collided.

[0063] It is understandable that in the triggered state, the elastic element 13 is in a stretched or compressed state, so that the elastic element 13 stores elastic potential energy.

[0064] After the detection device 11 separates from the object that collided with it, the detection device 11 is no longer squeezed by the object that collided with it, the elastic potential energy of the elastic element 13 is released, and the elastic element 13 applies a force to the moving part, thereby pushing the trigger area away from the sensing area so that the sensing device 14 can re-determine that the detection device 11 has not collided.

[0065] In this embodiment, the detection component 10 triggers the sensing device 14 through the relative movement of the moving part and the mounting member 12, which is beneficial for determining whether the detection device 11 has been hit. The elastic member 13 applies an elastic force to the moving part and the mounting member 12, which on the one hand helps to reduce the risk of false triggering due to contact between the trigger area and the sensing area caused by the vibration of the cleaning equipment itself, acceleration and deceleration changes, etc. On the other hand, it facilitates the automatic restoration of the position of the moving part after the detection device 11 separates from the object that has collided, which is convenient for timely judgment of subsequent collisions of the detection device 11.

[0066] Understandably, the first direction is the direction in which the cleaning equipment moves forward.

[0067] In some embodiments, the elastic element 13 is in a stretched or compressed state in the standby state, which helps to keep the position of the detection device 11 relatively stable in the standby state and improves the accuracy of the detection device 11 in detecting obstacles.

[0068] In some embodiments, referring to FIG5, the detection assembly 10 further includes a power supply 15, which is electrically connected to at least one of the detection device 11 and the sensing device 14, such that 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 function properly.

[0069] The specific type of power source 15 can be a silver-zinc battery, a lithium battery, etc.

[0070] The sensing device 14 can be a force sensor to convert the force signal received in the sensing area into an electrical signal.

[0071] In some embodiments, referring to Figures 3, 4 and 8, the mounting member 12 is provided with a mounting cavity 12a, one side of which is open. A portion of the detection device 11 is located within the mounting cavity 12a, and at least a portion of the sensing device 14 and at least a portion of the elastic member 13 are located within the mounting cavity 12a.

[0072] It is understandable that a portion of the detection device 11 is located outside the mounting 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 mounting cavity 12a.

[0073] In this way, the inner wall of the mounting cavity 12a can provide a certain degree of protection for the sensing device 14 and the elastic element 13, reducing the probability of the sensing device 14 and the elastic element 13 being damaged by collision.

[0074] Understandably, the detection device 11 includes various types of electronic components.

[0075] In some embodiments, referring to Figures 3 and 4, the detection device 11 includes a housing 111 and a device body 112. The housing 111 is provided with an installation space 111a. At least a portion of the device body 112 is located within the installation space 111a. One of the triggering area and the sensing device 14 is located in the housing 111, and the other is located on the inner wall of the installation cavity 12a.

[0076] The main body 112 of the device refers to the part of the detection device 11 used to realize the detection function, which includes various types of electronic components.

[0077] The cover 111 provides a certain degree of protection for the main body 112 of the device. In the event of a collision with the detection device 11, the cover 111 will take the place of the main body 112 and reduce the probability that the detection device 11 will fail to perform its detection function due to a collision.

[0078] In some embodiments where the detection device 11 is a lidar, at least a portion of the housing 111 is light-transmitting so that a laser beam can pass through the housing 111.

[0079] In some embodiments, referring to FIG3, the 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, and a portion of the cover 111 is located outside the mounting cavity 12a, and another portion is located inside the mounting cavity 12a.

[0080] This allows the mounting component 12 and the cover 111 to completely enclose the exterior of the device body 112, further reducing the probability of external objects colliding with the device body 112, thereby further improving the protection effect on the device body 112.

[0081] In some embodiments, referring to Figures 3 and 4, the mounting member 12 is fixed to the device body 112, the cover 111 forms a movable part, the elastic member 13 is located between the mounting member 12 and the cover 111, and the inner wall of the mounting space 111a is spaced apart from the device body 112.

[0082] In other words, the main body 112 of the device will not move relative to the mounting part 12, only the cover 111 can move relative to the mounting part 12 after the collision.

[0083] In this way, when the casing 111 is involved in a collision, the impact force it receives will not be directly transmitted to the main body 112 of the device, reducing the probability of the main body 112 of the device being damaged by the force.

[0084] It is understood that, in the standby state, the size of the gap between the inner wall of the mounting 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 housing 111 and the device body 112 still maintain the distance along the first direction.

[0085] In some embodiments where a power supply 15 is provided, referring to Figures 3 and 5, the power supply 15, the device body 112, and the sensing device 14 are all fixed to the mounting member 12 to reduce the probability of electrical connection interruption due to relative movement between the power supply 15 and the two.

[0086] In some embodiments, the mounting cavity 12a is open on the top side in the vertical direction, and the bottom wall of the mounting cavity 12a is used to support the device body 112.

[0087] The method of fixing the device body 112 and the mounting part 12 is not limited. For example, the device body 112 is provided with a threaded hole, and the mounting part 12 is provided with a through hole. The screw passes through the through hole and engages with the thread in the threaded hole to achieve a threaded connection between the two, so as to facilitate subsequent disassembly and assembly of the device body 112 for maintenance and replacement.

[0088] In some embodiments, referring to FIG3, the detection component 10 further includes a stop 16. One of the mounting component 12 and the detection device 11 is provided with the stop 16, and the other has a stop surface 12b. In the standby state, the stop 16 and the stop surface 12b are spaced apart along a first direction; in the triggered state, the stop 16 and the stop surface 12b abut against each other along the first direction.

[0089] By having the stop 16 and the stop surface 12b abut against each other in the triggered state, the movement of the moving part along the first direction is limited, which reduces the probability of damage to the sensing device 14 due to excessive force between the moving part and the sensing device 14 along the first direction, and helps to extend the service life of the sensing device 14.

[0090] The number of stop members 16 can be one or more; the number of stop surfaces 12b can also be one or more. There can be a one-to-one correspondence between one stop member 16 and one stop surface 12b; there can be a one stop member 16 and multiple stop surfaces 12b; or multiple stop members 16 and one stop surface 12b can cooperate.

[0091] The specific method of forming the stop surface 12b is not limited.

[0092] For example, referring to Figures 3 to 5 and Figure 8, one of the mounting member 12 and the detection device 11 is provided with a stop hole 12c. The extending direction of the stop hole 12c intersects with the first direction. At least a portion of the stop member 16 is embedded in the stop hole 12c along the extending direction of the stop hole 12c and is spaced apart from the inner wall of the stop hole 12c along the first direction. The stop hole 12c forms a stop surface 12b on one side of its inner wall along the first direction.

[0093] Understandably, the stop hole 12c is open on at least one side along its extension direction so that the stop member 16 is inserted into the stop hole 12c through the open position of the stop hole 12c.

[0094] 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 beneficial to guide the stop member 16 to move in the first direction until it contacts the stop surface 12b.

[0095] In some embodiments, referring to Figures 3 and 5, in the standby state, the stop member 16 abuts against the inner wall of one side of the stop hole 12c along the first direction.

[0096] In other words, both sides of the stop hole 12c along the first direction are closed ends, and the inner wall of one side forms the stop surface 12b.

[0097] This limits the travel of the stop member 16 along the first direction, thereby limiting the travel of the moving part relative to the mounting part, which is beneficial for the elastic member 13 to be in a stretched or compressed state in the standby state.

[0098] In some embodiments, referring to Figures 3 and 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 a second direction, and the first direction intersects the second direction. At least a portion of the first stop member 161 passes through the first stop hole 12d, and the first stop member 161 and the first stop hole 12d are rotatably engaged, with the axis of rotation extending along the second direction.

[0099] This allows at least a portion of the detection device 11 to rotate relative to the mounting component 12, thereby facilitating maintenance of the detection device 11 when the detection assembly 10 is disassembled, which improves the convenience of maintenance.

[0100] In some embodiments, the first direction and the second direction are perpendicular to each other to reduce the probability that the first stop 161 will disengage from the first stop hole 12d during the movement of the first stop 161 relative to the first stop hole 12d along the first direction.

[0101] In some embodiments, referring to FIG4, the first stop hole 12d is a through hole. On the one hand, this is beneficial to increase the size of the portion of the first stop member 161 in the first stop hole 12d along its extension direction, thereby reducing the probability that the first stop member 161 will come out of the first stop hole 12d. On the other hand, it is also convenient to clean the first stop hole 12d, thereby reducing the probability that foreign objects will enter the first stop hole 12d during the cleaning process and affect the movement of the first stop member 161.

[0102] In some embodiments with a housing 111 and a device body 112, referring to Figures 3 and 8, the housing 111 has a mounting space 111a, which is open on one side along a third direction and faces the mounting member 12. At least a portion of the device body 112 is located within the mounting space 111a and fixed to the mounting member 12. The housing 111 forms a movable part. One of the first stop member 161 and the first stop hole 12d is provided in the housing 111 and the other is provided in the mounting member 12. The first direction, the second direction and the third direction intersect each other.

[0103] In this way, the cover 111 can rotate relative to the mounting member 12. Without separating the mounting member 12 from the device body, the cover 111 can be rotated to a suitable position relative to the mounting member 12, so that the device body is removed from the installation space 111a and exposed to the outside, so as to carry out maintenance on the device body. This helps to simplify the maintenance steps and improve work efficiency.

[0104] In some embodiments, the first direction, the second direction, and the third direction are perpendicular to each other, thereby reducing the probability that the first stop 161 will disengage from the first stop hole 12d during the rotation of the housing 111 and the movement of the housing 111 relative to the mounting member 12 along the first direction.

[0105] In some embodiments, referring to FIG8, the first stop 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.

[0106] This helps to reduce the probability of interference between the first stop member 161 and the sensing device 14 due to the rotation of the first stop member 161 relative to the first stop hole 12d and its movement along the first direction, and also helps to reduce the size of the detection component 10 perpendicular to the first direction.

[0107] In some embodiments, referring to FIG8, the first stop 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.

[0108] This helps to reduce the probability of interference between the rotation of the first stop member 161 relative to the first stop hole 12d and the movement along the first direction and the extension and contraction of the elastic member 13, and helps to reduce the size of the detection assembly 10 perpendicular to the first direction.

[0109] The specific shape of the first stop hole 12d is not limited. For example, referring to Figure 3, the first stop hole 12d is an oblong hole, and the major axis of the first stop hole 12d is the first direction.

[0110] In some embodiments, referring to Figures 3 and 5, the stop 16 includes a second stop 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 is open along a third direction, 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 162 and the second stop hole 12e both extend along a third direction, the second stop hole 12e communicates with the mounting cavity 12a, and at least a portion of the second stop 162 passes through the second stop hole 12e.

[0111] During the process of inserting the detection device 11 into the mounting cavity 12a through the open position of the mounting cavity 12a in a third direction, at least part of the second stop 162 can be inserted into the second stop hole 12e simultaneously, which helps to simplify the assembly steps and improve work efficiency.

[0112] It is understandable that, referring to Figure 8, the second stop hole 12e is located on the side of the mounting cavity 12a away from its open position along a third direction.

[0113] In some embodiments, referring to FIG8, the second stop hole 12e penetrates the mounting member 12 in a third direction. On the one hand, this helps to increase the size of the second stop member 162 in the third direction in the second stop hole 12e, reducing the probability that the second stop member 162 will come out of the second stop hole 12e. On the other hand, it also reduces the probability that foreign objects will accumulate in the second stop hole 12e during the cleaning process and affect the movement of the second stop member 162.

[0114] In some embodiments, referring to FIG6, the second stop 162 is disposed 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 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. A part of the mounting member 12 is located between the detection device 11 and the limiting protrusion 1621 along the third direction.

[0115] A portion of the second stop 162 is located in the mounting cavity 12a, a portion is located in the second stop hole 12e, and a portion is located outside the mounting member 12.

[0116] Thus, by cooperating with the detection device 11, the relative position between the detection device 11 and the mounting part 12 along a third direction is restricted, reducing the probability that the second stop 162 will come out of the second stop hole 12e due to vibration, collision or other reasons.

[0117] The specific method of forming the limiting protrusion 1621 is not limited.

[0118] In an embodiment where the second stop hole 12e penetrates the mounting member 12, referring to Figures 6 and 8, the detection device 11 includes a threaded post extending in a third direction. The threaded post has a mounting threaded hole extending in a third direction. A portion of the threaded post is inserted into the second stop hole 12e from one side in the third direction. A screw is inserted into the threaded mounting hole from one side in the third direction of the second stop hole 12e. The screw nut forms a limiting protrusion 1621.

[0119] This ensures that the limiting protrusion 1621 will not interfere with the assembly between the second stop 162 and the second stop hole 12e.

[0120] It is understandable that the collision direction experienced by the detection device 11 may be parallel to the first direction or may form a certain angle with the first direction.

[0121] In some embodiments, referring to Figures 5 and 7, in a projection plane perpendicular to a 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 of the two 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.

[0122] Understandably, in the triggered state, the second stop 162 abuts against the inner wall of the second end 12g of the second stop hole 12e. In the event of a collision with the detection device 11, the second stop 162 moves from the first end 12f of the second stop hole 12e to the second end 12g.

[0123] When the collision direction forms a certain angle with the first direction, the collision force can be decomposed into a component force acting along the first direction and a component force acting perpendicular to the first direction. On the one hand, under the action of the component force acting along the first direction, the second stop member 162 can move relative to the second stop hole 12e along the first direction. On the other hand, since the size of the second stop hole 12e gradually increases along the second direction from the first end 12f to the second end 12g, it is beneficial that the second stop member 162 can move directly along the second direction under the action of the component force acting perpendicular to the first direction.

[0124] In this way, the probability of the second stop 162 abutting against the inner wall of the second stop hole 12e in the second direction during the movement of the second stop 162 relative to the second stop hole 12e in the first direction, thereby increasing the friction between the two, is reduced. This makes it easier for the second stop 162 to move to the second end 12g more smoothly and reduces the chance of the second stop 162 getting stuck during the movement.

[0125] In the projection plane perpendicular to the third direction, the projections of the inner walls on both sides of the second stop hole 12e 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 different impact directions of the detection device 11.

[0126] In some embodiments, the first direction and the second direction are two parallel directions in the horizontal direction, and the third direction is the vertical direction, with the mounting member 12 and the detection device 11 in contact along the third direction.

[0127] Thus, when the detection device 11 is impacted in the horizontal direction, the moving part can move relative to the mounting member 12 in the first direction and perpendicular to the first direction; when the detection device 11 is impacted in the horizontal direction, the moving part can move relative to the mounting member 12 in the first direction while the vertical component force can be transmitted to the mounting member 12, reducing the probability of the detection device 11 being damaged by bearing the vertical component force.

[0128] In some embodiments, referring to FIG7, in a projection plane perpendicular to a third direction, the projection of the inner wall of the first end 12f and 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. The projections of the inner walls on both sides of the second stop hole 12e along the second direction are symmetrical about the connecting line 12h.

[0129] The projections of the inner wall of the first end 12f and the inner wall of 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.

[0130] The second stop hole 12e is symmetrically arranged on both inner walls along the second direction, so that the second stop member 162 moves the same distance in both directions along the second direction during the process of moving from the first end 12f to the second end 12g, so as to better adapt to the different impact directions of the detection device 11.

[0131] Understandably, the inner walls on both sides of the second stop hole 12e along the second direction are respectively tangent to the inner wall of the first end 12f and the inner wall of the second end 12g, so as to improve the smoothness of the movement of the second stop member 162 within the second stop hole 12e.

[0132] In some embodiments with a housing 111 and a device body 112, referring to Figures 6 and 8, the housing 111 has a mounting space 111a, which is open on one side in a third direction to communicate with the mounting cavity 12a. At least a portion of the device body 112 is located within the mounting space 111a and fixed to the mounting member 12. The housing 111 forms a movable part. One of the second stop member 162 and the second stop hole 12e is provided in the housing 111 and the other is provided in the mounting member 12.

[0133] Thus, through the cooperation of the second stop 162 and the second stop hole 12e, the movement of the cover 111 relative to the mounting member 12 in the first direction can be limited; during the assembly of the detection assembly 10, the device body 112 can be fixed to the mounting member 12 first, and then the cover 111 can be placed over the outside of the device body 112 in the third direction and the second stop 162 can be cooperated with the second stop hole 12e.

[0134] In some embodiments, referring to FIG8, the mounting cavity 12a has a support rib 121 on the inner wall of the side opposite to its open position along the third direction. The support rib 121 protrudes from the inner wall of the mounting cavity 12a along the third direction and is used to abut against the cover 111 along the third direction.

[0135] This facilitates the limiting of the cover 111 along the third direction by the support rib 121 and the limiting protrusion 1621, reducing the risk of displacement of the detection component 10 along the third direction under the action of external forces.

[0136] The specific number of support bars 121 is not limited; it can be one; see Figure 8, or it can be multiple.

[0137] In some embodiments, referring to FIG8, the support rib 121 is provided with a limiting groove 121a. The limiting groove 121a is open on one side of the mounting cavity 12a in a third direction. A portion of the cover 111 can be embedded in the limiting groove 121a and abut against the inner wall of the limiting groove 121a in the third direction. At least one side of the limiting groove 121a in the first direction is a closed end, so that the inner wall of the closed end can stop and cooperate with the cover 111 in the first direction. The inner wall of the limiting groove 121a in the first direction limits the movement stroke of the cover 111 in the first direction.

[0138] The specific structural form of the elastic element 13 is not limited.

[0139] For example, referring to Figures 4 and 8, the elastic element 13 is a torsion spring, with two force-bearing ends of the torsion spring spaced apart along a 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.

[0140] The specific number of elastic elements 13 can be one or more.

[0141] In some embodiments where the elastic element 13 is a torsion spring, referring to FIG8, the mounting cavity 12a has a mounting post 122 on the inner wall of the side opposite to its open position along the third direction. The mounting post 122 extends along the third direction and passes through the inner wall of the torsion spring. In this way, the mounting post 122 plays a limiting role on the elastic element 13 along the first direction and the second direction.

[0142] This disclosure also provides a cleaning device. Referring to Figures 9 and 10, the cleaning device includes a body 20 and any of the detection components 10 in the foregoing embodiments. The detection component 10 is disposed on the body 20 so that when the body 20 is moving, the detection device 11 can detect obstacles on the moving path of the body 20.

[0143] In some embodiments, the cleaning equipment also includes a power unit connected to the body 20 for driving the body 20 to move.

[0144] In some embodiments, referring to Figures 9 and 10, the detection device 11 is located on top of the fuselage 20 so that the detection device 11 can have a wider detection range.

[0145] In some embodiments, referring to FIG9, the cleaning device further includes a drive device 30, the body 20 is provided with a receiving space 20a, the top side of the receiving space 20a is open, the drive device 30 and the detection component 10 are disposed in the receiving space 20a, the detection device 11 is disposed on the top of the mounting member 12, the drive device 30 is drivenly connected to the detection device 11, in the standby state, the drive device 30 drives at least a portion of the detection device 11 to extend out of the receiving space 20a, and in the triggered state, the drive device 30 drives at least a portion of the detection device 11 to retract into the receiving space 20a.

[0146] The drive unit 30 is used to drive the detection device 11 to move vertically. The detection device 11 can extend or retract into the receiving space 20a through the opening on the top side of the receiving space 20a.

[0147] In standby mode, at least a portion of the detection device 11 is located outside the receiving space 20a, so that the detection device 11 has a wider detection range; in the triggered mode, the detection device 11 retracts into the receiving space 20a, thereby realizing the protective function of the fuselage 20 for the detection device 11, and also enabling the detection device 11 to avoid external objects, thereby reducing the risk of the detection device 11 being damaged due to further contact with external objects.

[0148] The drive device 30 is connected to the detection device 11. Alternatively, the drive device 30 can be directly connected to the detection device 11 to drive its movement; or the mounting component 12 can be connected to the detection device 11, and the drive device 30 can drive the detection device 11 to move by driving the mounting component 12.
