The main chassis 20 is used for installing a walking assembly, the radar assembly 10 and a controller, the walking assembly is used for driving the cleaning equipment 100 to walk on a surface to be cleaned, the radar assembly 10 is used for measuring the distance between the cleaning equipment 100 and an obstacle and feeding back the distance to the controller, and the controller is used for controlling the cleaning equipment 100 to move to a proper position according to a signal fed back by the radar assembly 10 to adjust the moving direction so as to prevent the cleaning equipment 100 from colliding with the obstacle.

The following describes the structure of the radar unit 10 in the present application, taking the cleaning device 100 as an example of a sweeping and mopping integrated robot. The present embodiment is described as an example, and the technical scope of the present application is not limited thereto. It is understood that in other embodiments, the cleaning device 100 may also be embodied as other devices, such as a floor mopping robot, a window wiping robot, etc., without limitation.

Referring to fig. 2, the radar assembly 10 includes a radar base 11, a radar cover 12, a touch switch 13 and a radar 14, the radar base 11 is coupled in the main housing 20 and provides a supporting base for the radar cover 12, the touch switch 13 and the radar 14, the radar cover 12, the touch switch 13 and the radar 14 are all coupled to the radar base 11, the radar 14 is used for measuring a distance between the cleaning apparatus 100 and an obstacle and feeding back the distance to a controller, and the controller is used for controlling the cleaning apparatus 100 to move to a proper position according to a signal fed back by the radar 14 to adjust a moving direction so as to prevent the cleaning apparatus 100 from colliding with the obstacle. The radar cover 12 is used for protecting the radar 14 and preventing the radar 14 from being damaged when colliding with an external obstacle, the touch switch 13 is used for sending a trigger signal to the controller when the radar cover 12 is collided with the obstacle, and the controller controls the cleaning device 100 to adjust the traveling direction according to the trigger signal sent by the touch switch 13.

Specifically, the main chassis 20 has a mounting groove therein, and the radar base 11 is mounted in the mounting groove. The radar cover 12 and the radar base 11 are enclosed to form an accommodating cavity, specifically, the radar base 11 has an accommodating groove 110, the radar cover 12 covers the notch of the accommodating groove 110 and encloses with the groove wall of the accommodating groove 110 to form an accommodating cavity, moreover, the radar cover 12 protrudes out of the main chassis 20, the touch switch 13 and the radar 14 are both accommodated in the accommodating cavity to prevent the touch switch 13 and the radar 14 from being damaged under the collision of obstacles, so that the cleaning device 100 has a long service life.

More specifically, the radar 14 may be mounted to the radar base 11 by screws, pins, or other fastening structures. In the embodiment, the bottom of the receiving groove 110 is provided with a bayonet 112, the radar 14 is clamped at the bayonet 112 for fixing, and the radar 14 can be conveniently installed by providing the bayonet 112.

Referring to fig. 3 and 4, the radar cover 12 is movably coupled to the radar base 11 and can slide relative to the radar base 11 in a first direction (as indicated by arrow a in fig. 5) and/or a second direction (as indicated by arrow b in fig. 5) intersecting the first direction. The touch switch 13 is located between the radar cover 12 and the radar base 11, the touch switch 13 has a touch surface 132, and the touch surface 132 is located on a path along which the radar cover 12 slides in the first direction and the second direction. During the sliding of the radar cover 12 in the first direction and/or the second direction, the radar cover 12 presses the touch surface 132 to allow the touch switch 13 to operate.

As can be appreciated, since the radar cover 12 protrudes from the main chassis 20, if the radar 14 fails to operate during the travel of the cleaning device 100, the radar cover 12 is likely to collide with an obstacle, which may cause the radar cover 12 to slide in the first direction and/or the second direction with respect to the radar base 11. Specifically, the first direction is a direction opposite to the traveling direction, and the second direction is a direction perpendicular or substantially perpendicular to the first direction. Generally, the surface to be cleaned is a horizontal surface, and when the cleaning device 100 walks on the surface to be cleaned, the obstacle located in the traveling direction and the obstacle located above the cleaning device 100 most easily collide with the radar cover 12, so the following embodiments are described by taking the first direction as a horizontal direction and the second direction as a vertical downward direction as an example.

In the conventional cleaning apparatus 100, a plurality of touch switches 13 are disposed on the radar base 11, each touch switch 13 has only one touch surface 132, wherein a portion of the touch surfaces 132 of the touch switches 13 extend in a first direction, and the remaining portion of the touch surfaces 132 of the touch switches 13 extend in a second direction. The touch switch 13 with the touch surface 132 extending along the first direction is defined as a first touch switch 13, the touch surface 132 of the first touch switch 13 is defined as a first touch surface 132, the touch switch 13 with the touch surface 132 extending along the second direction is defined as a second touch switch 13, the touch surface 132 of the second touch switch 13 is defined as a second touch surface 132, the first touch surface 132 is located on a sliding path of the radar cover 12 sliding along the second direction, and the second touch surface 132 is located on the sliding path of the radar cover 12 sliding along the first direction.

When the radar cover 12 collides with an obstacle located above the cleaning device 100, the radar cover 12 is pressed by the obstacle to slide in a vertical downward direction and press against the first touch surface 132, and then the first touch switch 13 is triggered and can send a trigger signal to the controller, and the controller controls the traveling assembly to drive the main case 20 and the part connected to the main case 20 to retreat so as to avoid the obstacle located above; when the radar cover 12 collides with an obstacle located in the traveling direction of the cleaning apparatus 100, the radar cover 12 is pressed by the obstacle to slide in a backward direction opposite to the traveling direction and press against the second touch surface 132, and then the second touch switch 13 is triggered and can send a trigger signal to the controller, and the controller controls the cleaning apparatus 100 to move backward to avoid the obstacle located in the traveling direction. In the conventional cleaning apparatus 100, the assembly of the cleaning apparatus 100 is complicated due to the large number of the touch switches 13.

In addition, in the present application, the touch surface 132 is located on the path along which the radar cover 12 slides along the first direction and the second direction, so that when the radar cover 12 collides with an obstacle and moves along the first direction and/or the second direction, both the touch surface 132 and the touch surface 132 of the touch switch 13 can be pressed against each other and trigger the touch switch 13 to operate, and thus, only a single touch switch 13 is set, so that the sliding operation of the radar cover 12 along the first direction and/or the second direction can be obtained and the touch switch 13 is triggered to transmit a trigger signal. Therefore, the arrangement of a single touch switch 13 has better assembly simplicity compared with the conventional arrangement of a plurality of touch switches 13.

It can be understood that, in the present application, only one touch switch 13 may be provided, one touch switch 13 is provided in front of the traveling direction of the main chassis 20, the radar cover 12 slides along the first direction relative to the radar base 11 when being collided by an obstacle located in front of the traveling direction of the cleaning apparatus 100, the radar cover 12 slides along the second direction relative to the radar base 11 when being collided by an obstacle located above the cleaning apparatus 100, the touch switch 13 can be triggered to send a trigger signal to the controller regardless of the sliding of the radar cover 12 along the first direction and/or the second direction, and the controller controls the cleaning apparatus 100 to move backward.

Specifically, the touching surface 132 is configured to be disposed obliquely with respect to the first direction and the second direction, and the radar cover 12 has a pressing surface 121 disposed toward the touching surface 132, and the pressing surface 121 presses the touching surface 132. Through setting up the face 121 that supports, at the in-process that radar lid 12 slided and supports with touch face 132, be the face contact between radar lid 12 and the touch face 132, compare in the contact for the point between radar lid 12 and the touch face 132, the touching scope is wider to in time trigger touch switch 13 work of being accurate.

Referring to fig. 5, specifically, taking the example of fig. 5 in which the cleaning apparatus 100 is horizontally disposed, the traveling direction of the cleaning apparatus 100 is a horizontal left direction, the first direction is a horizontal right direction, and the second direction is a vertical downward direction, the touch surface 132 is disposed in an inclined manner relative to the first direction and the second direction, and an included angle between the touch surface 132 and the horizontal plane is smaller than 90 ° (the included angle is an angle from the horizontal plane to the touch surface 132 along the counterclockwise direction c).

Referring to fig. 6, in particular, the radar cover 12 includes a cover main body 122 and a pressing portion 123, the cover main body 122 covers the radar base 11 and has an installation surface 124 facing the radar base 11, the pressing portion 123 protrudes from the installation surface 124, and a pressing surface 121 is formed on a surface of the pressing portion 123 facing the touch surface 132. It is to be understood that the pressing portion 123 may be integrally formed with the cover main body 122 or separately formed. When the cover main body 122 collides with an obstacle, the cover main body 122 can synchronously drive the pressing portion 123 to slide along the first direction and/or the second direction relative to the radar base 11 and to press against the touch surface 132.

Further, the inclination angle of the touch surface 132 with respect to the first direction and the second direction is 45 °. That is, the contact surface 132 is inclined at an angle of 45 ° to both the horizontal direction and the vertical direction. The inclination angle of the touch surface 132 with respect to the first direction is defined as a first inclination angle d, and the inclination angle of the touch surface 132 with respect to the second direction is defined as a second inclination angle e, i.e. the first inclination angle d and the second inclination angle e are both 45 °. It is defined that in the process that the pressing portion 123 slides along the first direction and/or the second direction and presses against the touch surface 132, the pressing force applied by the pressing portion 123 to the touch surface 132 along the first direction is a first pressing force, the pressing force applied by the pressing portion 123 to the touch surface 132 along the second direction is a second pressing force, according to the principle of physical force decomposition, the first pressing force can decompose a first pressing component force perpendicular to the touch surface 132 and directed to the touch surface 132, and the second pressing force can decompose a second pressing component force perpendicular to the touch surface 132 and directed to the touch surface 132, and it can be understood that the first pressing component force and the second pressing component force are the forces actually applied to the touch surface 132 by the first pressing force and the second pressing component force, respectively. Because the inclination angles of the touch surface 132 relative to the first direction and the second direction are both 45 °, under the condition that the first abutting force and the second abutting force are relatively close, the first abutting component force and the second abutting component force received by the touch surface 132 are also relatively close, so that the touch surface 132 is not stressed too much or too little when being respectively subjected to the first abutting component force or the second abutting component force, and thus, the touch surface 132 can be prevented from being damaged due to too much stress, and the touch surface 132 can be prevented from being stressed too little so as not to send a trigger signal to the controller in time.

Further, the pressing surface 121 is disposed opposite to and parallel to the touch surface 132. Therefore, when the pressing surface 121 presses against the touch surface 132, the pressing surface 121 can be directly attached to the touch surface 132, so that on one hand, the pressure of the pressing portion 123 acting on the touch surface 132 can be reduced to prevent the touch surface 132 from being damaged due to excessive stress, and on the other hand, the pressing area between the pressing surface 121 and the touch surface 132 can be increased, so that multiple areas of the touch surface 132 can timely and accurately receive the touch of the pressing surface 121, and the touch accuracy of the touch switch 13 can be improved.

Further, in a projection direction perpendicular to the inclined direction of the touch surface 132, the orthographic projection of the pressing surface 121 on the touch surface 132 completely covers the touch surface 132. Thus, even if the pressing portion 123 slightly shakes with respect to the touch surface 132, the pressing portion can be pressed against the touch surface 132 during the sliding process, and the touch reliability of the touch switch 13 can be improved.

Referring to fig. 2 again, and also referring to fig. 7, the radar base 11 has a supporting inclined plane 114 for supporting the touch switch 13, and the supporting inclined plane 114 is disposed parallel to the touch surface 132. It is understood that the supporting slope 114 is also disposed obliquely to the first and second directions. Compared with the supporting surface being horizontally disposed, by disposing the supporting inclined surface 114 on the radar base 11, the supporting inclined surface 114 can effectively support the touch switch 13 during the sliding of the pressing portion 123 along the first direction and the second direction and the pressing against the touch surface 132, so as to prevent the touch switch 13 from sliding relative to the radar base 11.

Specifically, the radar base 11 includes a base main body 115 and a supporting body 116, the receiving groove 110 is formed in the base main body 115, the supporting body 116 is disposed on a surface of the base main body 115 facing the radar cover 12, and a supporting inclined surface 114 is formed at an end of the supporting body 116 away from the base main body 115.

Referring again to fig. 2 and 7, in an embodiment, the radar assembly 10 further includes a first reset element 15, and the first reset element 15 is configured to provide a first reset force opposite to the first direction when the radar cover 12 slides along the first direction. That is to say, when the radar cover 12 triggers the touch switch 13, the controller controls the cleaning device 100 to move backward, the acting force of the obstacle on the radar cover 12 disappears, and under the action of the first reset piece 15, the radar cover 12 can slide along the first reset direction opposite to the first direction to automatically reset, so as to facilitate the intelligentization of the cleaning device 100.

Alternatively, the first restoring member 15 may be a compression spring, an elastic arm, or the like. In an embodiment, the first restoring member 15 is an elastic arm, and the elastic arm is received in the receiving slot 110 and protrudes out of the slot sidewall of the receiving slot 110. Specifically, one end of the elastic arm is coupled to the groove sidewall of the receiving groove 110, and the other end is spaced apart from the groove sidewall of the receiving groove 110. When the radar cover 12 is pressed against an obstacle and the radar cover 12 slides in a first direction under the action of the obstacle, the radar cover 12 contacts the elastic arm and presses the elastic arm, and when the acting force of the obstacle disappears, the radar cover 12 slides in a first reset direction opposite to the first direction and resets under the action of the elastic arm. Through setting up first piece 15 that resets for the elastic arm, compare in setting up compression spring, the elastic arm rocks for a short time at the compression or the in-process that resets to promote the gliding stability of radar lid 12 along first direction and first direction that resets.

Further, radar assembly 10 also includes a second return member 16, and second return member 16 is configured to provide a second return force opposite the second direction when radar cover 12 is slid in the second direction. Alternatively, the second restoring member 16 may be a compression spring, an elastic arm, or the like. In an embodiment, the second restoring member 16 is an elastic arm, and the elastic arm is received in the receiving slot 110 and protrudes out of the bottom of the receiving slot 110. Specifically, one end of the elastic arm is coupled to the bottom of the receiving groove 110, and the other end is spaced from the bottom of the receiving groove 110. When the radar cover 12 is pressed against the obstacle and the radar cover 12 slides in the second direction under the action of the obstacle, the radar cover 12 contacts the elastic arm and presses the elastic arm, and when the acting force of the obstacle disappears, the radar cover 12 slides in a second reset direction opposite to the second direction and resets under the action of the elastic arm. Through setting up the second and reseing to the elastic arm, compare in setting up the second piece 16 that resets for compression spring, the elastic arm rocks for a short time at the compression or in-process that resets to promote radar lid 12 along the gliding stability of second direction and second direction that resets.

In one embodiment, there are a plurality of second restoring members 16, and a plurality of second restoring members 16 are disposed at intervals along the circumferential direction of cover main body 122. Through setting up a plurality of second piece 16 that resets, can effectively promote radar lid 12 along the gliding stability of second direction and second direction that resets.

Above-mentioned radar subassembly 10 and be equipped with its cleaning equipment 100 is located radar lid 12 along the gliding route of first direction and second direction through setting up touch surface 132, therefore, when radar lid 12 and barrier bump and along the in-process of first direction and/or second direction removal, all can support with touch surface 132 of touch switch 13 and press and trigger the touch switch 13 action, so, only single touch switch 13 alright acquire the motion of radar lid 12 along first direction and/or second direction for radar subassembly 10 and the cleaning equipment 100 that is equipped with it have better assembly simplicity.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
