[0049] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0050] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0051] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0052] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

[0053] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0054] See also Figure 1 , Figure 2 and Figure 3 In one embodiment of the present application, a cover structure 1 is provided, comprising a support 11, a cover 12, a first elastic component 13 and a first switch 14. The cover 12 is connected to the support 11 so as to be linearly movable between a first position and a second position along a first direction, and defines a receiving cavity together with the support 11. The first elastic component 13 connects the support 11 and the cover 12, and is used to provide a tendency force for the cover 12 to return from the second position to the first position. The first switch 14 has a first fixed end and a first trigger end, the first fixed end is connected to one of the support 11 and the cover 12, and the first trigger end faces the other of the support 11 and the cover 12. When the cover 12 is in the first position, there is a gap between the first trigger end and one of the support 11 and the cover 12, and when the cover 12 is in the second position, the first trigger end contacts the other of the support 11 and the cover 12.

[0055] In the above-mentioned cover structure 1, during actual operation, the support 11 is fixed on the equipment body. During the forward movement of the body, when the cover 12 does not collide with the obstacle, the cover 12 is in the first position. At this time, there is a gap between the first trigger end of the first switch 14 and the cover 12 or the support 11, and the avoidance signal cannot be triggered. When the cover 12 collides with the obstacle, the obstacle applies a collision force to the cover 12. Under the action of the collision force, the cover 12 retreats in the first direction, and the first trigger end of the first switch 14 is touched, thereby triggering the avoidance signal. The control system on the body controls the body to turn according to the avoidance signal to avoid the obstacle. At the same time, when the cover 12 retreats in the first direction, it acts on the first elastic component 13, so that the first elastic component 13 provides a tendency force for the cover 12 to return to the first position. When the body avoids the obstacle, the collision force acting on the cover 12 is released, and the cover 12 returns to the first position under the action of the tendency force provided by the first elastic component 13.

[0056] Compared with the prior art, when encountering an obstacle, the cover 12 moving along the support 11 can make the first switch 14 generate an avoidance signal, thereby realizing the obstacle avoidance of the machine body and avoiding structural damage caused by the continued advancement of the machine body, thereby ensuring that the radar 2 installed in the installation cavity is protected from damage; at the same time, under the action of the first elastic component 13, the cover 12 can return to the initial working position to ensure that the machine body can operate normally. In addition, the movement of the cover 12 is limited to one direction, and only the reset element and the switch element need to be set in this direction, which helps to reduce the number of parts and is also convenient for assembly.

[0057] The first elastic component 13 can be arranged on the side of the cover 12 corresponding to the forward direction of the machine body. In this case, when the cover 12 retreats under the impact force, the first elastic component 13 is stretched and provides a tendency force for the cover 12 to approach the support 11. The first elastic component 13 can also be arranged on the side of the cover 12 corresponding to the backward direction of the machine body. In this case, when the cover 12 retreats under the impact force, the first elastic component 13 is compressed and provides a tendency force for the cover 12 to move away from the support 11. Alternatively, the first elastic component 13 can be arranged on both sides of the cover 12 and the forward direction and the backward direction of the machine body.

[0058] The first switch 14 may be a micro switch or a touch switch. When the first trigger end is pressed, the first switch 14 can generate an avoidance signal. The control system of the machine body responds to the avoidance signal and controls the machine body to turn to avoid.

[0059] Preferably, the cover 12 is a plane-symmetrical structure, the first elastic component 13 is located on the symmetry plane of the cover 12, and the symmetry plane of the cover 12 is parallel to the first direction.

[0060] In order to enable the cover 12 to be movably arranged on the support 11 along the first direction, a slide rail extending along the first direction may be arranged on the support 11, and a slider cooperating therewith may be arranged on the cover 12, and when the slider moves along the slide rail, the cover 12 may move on the support 11. The structures of the following embodiments may also be adopted.

[0061] In some embodiments, see Figure 4 , Figure 5 and Figure 6 The cover structure 1 further includes a connecting column 116 and a limiting portion 117. The first end of the connecting column 116 is provided at one of the support 11 and the cover 12. The second end of the connecting column 116 opposite to the first end is connected to the limiting portion 117. The other of the support 11 and the cover 12 has a connecting hole 123. The connecting column 116 is passed through the connecting hole 123 and can move relative to the connecting hole 123 along a first direction under the action of an external force; the connecting hole 123 is located between the limiting portion 117 and the first end of the connecting column 116. In this way, the support 11 and the cover 12 are connected by the connecting column 116 and the limiting portion 117, and can move relative to the connecting column 116 along the first direction through the connecting hole 123, thereby realizing the movable connection of the cover 12 to the support 11. This structure is simple and convenient for assembling the cover structure 1.

[0062] It can be understood that the minimum outer dimension of the limiting portion 117 is greater than the maximum aperture of the connecting hole 123 , so that the cover 12 can be prevented from escaping from the connecting column 116 .

[0063] Optionally, the connection column 116 is a screw column, one end of which has an internal thread hole, and the stopper 117 is a screw, the external thread of which is screwed into the internal thread hole of the screw column. The nut size of the screw is larger than the maximum aperture of the connection hole 123.

[0064] In order to achieve relative movement between the connection hole 123 and the connection column 116 along the first direction, in a feasible embodiment, the connection column 116 extends longitudinally along the first direction, and the axial direction of the connection hole 123 is along the first direction. At this time, the cover 12 moves along the extension direction of the connection column 116, that is, the cover 12 moves along the first direction. Of course, the movement of the cover 12 can also be achieved by adopting the arrangement of the connection column 116 and the connection hole 123 in the following embodiments.

[0065] In some embodiments, see Figure 7 , Figure 8 and Fig. 9The connecting column 116 is protruded on the support 11 along a second direction intersecting the first direction. The connecting hole 123 has a first guide surface 124 and a second guide surface 125 opposite to each other. The first guide surface 124 and the second guide surface 125 both extend along the first direction. The connecting column 116 is connected between the first guide surface 124 and the second guide surface 125, and moves in the connecting hole 123 along the first guide surface 124 and the second guide surface 125.

[0066] At this time, the connecting column 116 is arranged on the support 11, and the connecting hole 123 is located on the cover shell, which is convenient for transfer and maintenance. At the same time, the connecting hole 123 is a strip hole, having a first guide surface 124 and a second guide surface 125 relative to each other. When the cover 12 is retreated by the collision force, since the first guide surface 124 and the second guide surface 125 are both in contact with the connecting column 116, under the restriction of the connecting column 116, the cover 12 can only move along the first direction, and cannot move in the direction perpendicular to the first guide surface 124 and the second guide surface 125. In addition, under the guidance of the first guide surface 124 and the second guide surface 125, the cover 12 can move along the first direction relative to the connecting column 116. In this way, the movement of the cover 12 is restricted to one direction.

[0067] Preferably, the second direction is perpendicular to the first direction. In this way, the movement in the first direction and the movement in the second direction can be independent of each other, which is convenient for motion control. In actual operation, the first direction can be the forward direction of the cleaning robot, and the second direction can be the vertical direction.

[0068] It is understandable that the moving range of the cover 12 can be determined by determining the extension length of the first guide surface 124 and the second guide surface 125, which facilitates the design. Compared with guide structures such as guide grooves, the bar-shaped connecting hole 123 has a self-limiting function and can simplify the structure.

[0069] Preferably, the cross section of the connecting column 116 is circular, and the connecting column 116 is tangent to the first guide surface 124 and the second guide surface 125. This helps to reduce the friction between the connecting column 116 and the first guide surface 124 and the second guide surface 125, and improves the collision response accuracy of the cover 12.

[0070] In some embodiments, there are multiple connecting posts 116, and the multiple connecting posts 116 are arranged at intervals around the mounting portion, so that the movement of the cover 12 is more stable.

[0071] It can be understood that there are multiple connection holes 123 and multiple limiting portions 117, and the multiple connection columns 116, the multiple connection holes 123 and the multiple limiting portions 117 correspond one to one.

[0072] Preferably, there are three connecting posts 116, which are arranged in an isosceles triangle, and the center of one of the connecting posts 116 is located on the symmetrical cross section of the cover 12. In this way, the third connecting post 116 is arranged in a plane-symmetrical manner, further improving the movement stability of the cover 12.

[0073] In some embodiments, see Figure 6 and Figure 7 The support 11 is provided with a first boss 113 protruding along the second direction, the first boss 113 has a mounting hole 114, the connecting column 116 is matched with the mounting hole 114, and the cover 12 is slidably arranged on the first boss 113. At this time, the connecting column 116 is installed through the mounting hole 114 on the first boss 113, and the cover 12 is supported to slide by the protruding first boss 113, which can reduce the friction between the cover 12 and the support 11 during the movement, so that the cover 12 can quickly retreat under the action of the collision force, and the first switch 14 can be triggered in time to achieve rapid avoidance of the body, reducing the risk of damage to the cover structure 1 and the internal structure.

[0074] In some embodiments, the support 11 is further provided with a sliding protrusion 115 protruding along the second direction, and the cover 12 is slidably located on the sliding protrusion 115. At this time, by providing the sliding protrusion 115, the support force of the support 11 and the cover 12 is increased, and the movement stability of the cover 12 is improved.

[0075] Specifically in the embodiment, Figure 8 and Fig. 9 The cover 12 includes a barrel 121, a flat plate 122, a transition wall 128 and a slide plate 129. The barrel 121 has a closed end and an open end opposite to each other along the second direction. The flat plate 122 is arranged at an angle to the barrel 121. The flat plate 122 has a through opening, and the open end is connected to the opening of the flat plate 122. One end of the transition wall 128 is connected to the edge of the flat plate 122, and the other end of the transition wall 128 protrudes toward the support 11. The slide plate 129 is connected to the other end of the transition wall 128 and protrudes toward the first direction. The slide plate 129 is slidably disposed on the sliding protrusion 115, and the connecting hole 123 is located on the flat plate 122. The switch retaining rib 127 and the second spring seat 126 are vertically disposed on the slide plate 129 and protrude toward the support 11.

[0076] Furthermore, a second boss 1210 protrudes from the flat plate portion 122 toward the support 11, and the connection hole 123 passes through the second boss 1210, and the second boss 1210 is slidably connected to the first boss 113. In this way, the cover 12 can slide on the support 11 by matching the first boss 113 with the second boss 1210 and the sliding plate portion 129 with the sliding protrusion 115.

[0077] In some embodiments, see Figure 3 , Figure 6 and Figure 7 The first elastic component 13 is a return spring. The support 11 is provided with a first spring seat 111, and the cover 12 is provided with a second spring seat 126. The return spring has a fixed end and a sleeve end opposite to each other in the first direction. The fixed end of the return spring is fixedly connected to one of the first spring seat 111 and the second spring seat 126, and the sleeve end of the return spring is sleeved to the other of the first spring seat 111 and the second spring seat 126. Using the return spring as the first elastic component 13 can provide sufficient force to return the cover 12 to the first position. At the same time, one end of the return spring is fixed and the other end is sleeved, which is convenient for disassembly and assembly.

[0078] In some embodiments, see Figure 6 and Fig. 9 A first switch seat 112 is provided on the support 11 , a switch retaining rib 127 is provided on the cover 12 , the first fixed end is mounted on the first switch seat 112 , and the first trigger end is opposite to the switch retaining rib 127 .

[0079] In actual operation, when the cover 12 is located at the first position, there is a gap between the first trigger end and the switch retaining rib 127, and the avoidance signal is not triggered. When the cover 12 is located at the second position, the switch retaining rib 127 moves with the cover 12 to contact the first trigger end, so that the first switch 14 generates a avoidance signal.

[0080] The provision of the switch retaining rib 127 helps to strengthen the structural strength of the cover 12 relative to the first trigger end, thereby increasing the service life of the cover structure 1 and ensuring the timeliness of the device body avoidance.

[0081] In some embodiments, see Figure 6 , Figure 7 and Figure 8 , the cover 12 can also be movably connected to the support 11 between the first position and the third position along the second direction, the cover structure 1 also includes a second elastic component 15 and a second switch 16, the second elastic component 15 connects the cover 12 and the support 11, and is used to provide a tendency force for the cover 12 to return from the third position to the first position, the second switch 16 has a second fixed end and a second trigger end, the second fixed end is connected to one of the support 11 and the cover 12, and the second trigger end faces the other of the support 11 and the cover 12. Wherein, when the cover 12 is located at the first position, there is a gap between the second trigger end and one of the support 11 and the cover 12, and when the cover 12 is located at the second position, the second trigger end contacts the other of the support 11 and the cover 12.

[0082] In actual operation, the first direction is the direction located in the horizontal plane, and the second direction is the vertical direction. When the device body moves to the bottom of the bed, the bottom of the sofa or the bottom of the table, the cover 12 can move toward the support 11 under the collision of the obstacle to reduce the protruding height. At the same time, the second trigger end is triggered to make the second switch 16 generate an avoidance signal, and the body control system controls the body to perform an avoidance action according to the avoidance signal. In this way, the device body can have obstacle avoidance functions in both the horizontal and vertical directions.

[0083] It can be understood that when the cover 12 is located at the first position, the first elastic component 13 and the second elastic component 15 are in an initial state and have no elastic force.

[0084] In some embodiments, see Figure 8 and Fig. 9 The second elastic member 15 is a spring sheet, one end of which is fixed to one of the support 11 and the cover 12, and the other end of which is in contact with the other of the support 11 and the cover 12. At this time, the cover 12 is supported by the second elastic part, so that the cover 12 is in a floating state. The setting of the spring sheet can generate a large tendency force within a small moving distance, so that the cover 12 can be quickly reset, which helps to reduce the overall height of the machine body.

[0085] Specifically in the embodiment, the spring sheet includes a connected fixing portion and an elastic wall, the fixing portion is fixedly connected to the cover 12, and the elastic wall has an abutting portion protruding toward the support 11, and the abutting portion abuts against the support 11. When the cover 12 is pressed down and moves toward the third position, the elastic wall is compressed, thereby providing a tendency force for the cover 12 to return to the first position.

[0086] In order to enable the cover 12 to move along the second direction, a guide column or the like may be separately provided in the second direction.

[0087] In some embodiments, in order to simplify the cover structure 1, the longitudinal direction of the connecting column 116 is arranged along the second direction, and the cover 12 moves along the connecting column 116 through the connecting hole 123. At the same time, there is a spacing between the limiting portion 117 and the end surface of the connecting hole 123 facing the limiting portion 117, and the size of this spacing is equivalent to the length of the second elastic component 15 in the initial state, so as to support the cover 12 to float in the second direction and to be stable in the first position.

[0088] Specifically in the embodiment, there are two second elastic components 15 , and the two second elastic components 15 are symmetrically arranged along a central cross section among a plurality of cross sections of the cover 12 parallel to the first direction and the second direction.

[0089] At this time, the cover 12 is a plane-symmetrical structure, and the two second elastic components 15 are symmetrically arranged along the central cross section of the cover 12, which is conducive to ensuring the movement stability of the cover 12 in the second direction.

[0090] In some embodiments, a second switch seat is provided on the support 11 , a second fixed end of the second switch 16 is mounted on the second switch seat, and a second trigger end of the second switch 16 is opposite to the cover 12 .

[0091] In some embodiments, see Fig.10 The cover structure 1 further includes a base 17, the support 11 is fixedly connected to the base 17, and the base 17 and the cover 12 are arranged on opposite sides of the support 11. In actual application, the cover structure 1 is installed on the equipment body by fixing the base 17 to the equipment body.

[0092] In some embodiments, see Figure 1 and Figure 2 The cover structure 1 further includes an upper shell 18, which is connected to the base 17 and defines an installation cavity. The support 11 and the cover 12 are located in the installation cavity, and an opening is provided on the upper shell 18, and the cover 12 partially extends out of the opening.

[0093] Specifically in the embodiment, in order to achieve the fixed connection between the base 17 and the support 11, the end of the connecting column 116 away from the cover 12 extends out of the mounting hole 114 on the first boss 113 and is fixed to the base 17. For example, the connecting column 116 and the base 17 are integrally formed. In this way, the connection between the base 17, the support 11 and the cover 12 is achieved through a connecting column 116, which greatly simplifies the structure. The setting of the connecting column 116 can also perform positioning assembly, speeding up the assembly process.

[0094] The cover assembly provided in the embodiment of the present application, when encountering an obstacle, the cover 12 moving along the support 11 can make the first switch 14 generate an avoidance signal, thereby realizing the obstacle avoidance of the machine body and avoiding structural damage caused by the continued advancement of the machine body, thereby ensuring that the radar 2 installed in the installation cavity is protected from damage; at the same time, under the action of the first elastic component 13, the cover 12 can return to the initial working position to ensure that the machine body can operate normally. In addition, the movement of the cover 12 is limited to one direction, and only the reset element and the switch element need to be set in this direction, which helps to reduce the number of parts and is also convenient for assembly.

[0095] In addition, some embodiments of the present application further provide a radar assembly, including a radar 2 and a cover structure 1 provided in any of the above embodiments, wherein the radar 2 is disposed in the accommodating cavity. Since the radar assembly includes the cover structure 1, it has all the beneficial effects of the above embodiments, which will not be described in detail here.

[0096] Specifically in the embodiment, a mounting portion is provided on the support 11 , the mounting portion is located in the accommodating cavity, and the radar 2 is mounted on the mounting portion.

[0097] Furthermore, an avoidance hole for detection by the radar 2 is provided on the cover 12 to avoid the light emitted by the radar 2 .

[0098] Furthermore, the radar assembly also includes a driving unit, which is arranged in the accommodating cavity and is used to drive the radar 2 to rotate, so as to help the radar 2 rotate within a range of 360 degrees and obtain all-round environmental information.

[0099] Optionally, the driving unit includes a synchronous belt and a rotating shaft. When the rotating shaft rotates, the radar 2 is driven to rotate through the synchronous belt, and the rotating axis of the radar 2 is parallel to the second direction.

[0100] Among them, radar 2 can be an ultrasonic radar, a laser radar, a millimeter wave radar, etc.

[0101] In addition, some embodiments of the present application further provide a cleaning robot, which includes the above radar assembly. Since the cleaning robot includes the above cover structure 1, it has all the beneficial effects of the above embodiments, which will not be repeated here.

[0102] Preferably, the cleaning robot is a sweeping robot, a mopping robot or a sweeping and mopping robot.

[0103] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features of the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0104] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
