[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0032] In addition, the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their 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 addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0033] Reference Figures 1 to 6 An embodiment of the present application provides a surface shell assembly 100, which is arranged on a cleaning robot, and the surface shell assembly 100 includes a middle shell 110, a radar 120 and a protective cover 121, wherein the middle shell 110 is provided with a radar mounting hole 111 and a groove 114, the groove 114 is formed by the inner concave of the middle shell 110 and surrounds the radar mounting hole 111, the radar 120 is arranged in the radar mounting hole 111 of the middle shell 110, and the protective cover 121 of the radar 120 is covered on the radar 120 and shields the radar mounting hole 111 and the groove 114.

[0034] Specifically, the radar 120 used in the face shell assembly 100 of the embodiment of the present application is a laser radar, preferably a D-TOF (direct Time-of-Flight) radar. The basic principle of the D-TOF radar is to send a pulse signal, calculate the time difference from the emission to the reception of the signal, and then calculate the distance of the object by the speed of sound. Compared with binocular vision and structured light solutions, the DTOF radar is relatively simple to implement, does not rely on lighting and environmental texture, has a small amount of calculation, a long measurement distance, a relatively low cost, a long service life, and is generally cost-effective.

[0035] During the operation of the cleaning robot, the radar does not need to rotate or can rotate slightly. The radar 120 is arranged in the radar mounting hole 111 of the middle shell 110. The protective cover 121 of the radar 120 is arranged on the radar 120 and covers the radar mounting hole 111 and the groove 114. The middle shell 110 is concave to form the groove 114. The position of the groove 114 is lower than that of other areas of the middle shell 110. Therefore, after the water flows into the middle shell 110 through the protective cover 121, it will converge into the groove 114, and will not enter the middle shell 110 through the radar mounting hole 111. The middle shell 110 is provided with a drain port 115 on the bottom wall of the groove 114. The water will flow out through the drain port 115, thereby preventing the water from entering the middle shell 110 through the holes on the middle shell 110, so as to further prevent the components inside the middle shell 110, such as the main board, from being damaged by water, thereby ensuring the waterproof effect of the face shell assembly 100 and ensuring the stable operation of the cleaning robot.

[0036] When installing the face shell assembly 100, first install the radar 120 onto the middle shell 110 from the bottom of the middle shell 110 from bottom to top, and finally snap the protective cover 121 into the groove 114 above the middle shell 110 to complete the installation of the face shell assembly 100. The above installation process is simple.

[0037] In summary, the face shell assembly 100 provided in the embodiment of the present application can ensure the waterproof effect of the sealing structure by optimizing the structure of the middle shell 110, and the installation process is simple and cost-saving.

[0038] It can be understood that in order for the protective cover 121 to have an anti-collision function, when the protective cover 121 is snapped onto the middle shell 110, it is snapped onto the middle shell 110 through four snaps, some of which are snapped into the circular through holes so that they can rotate slightly, and some of the snaps leave space when snapped together so that they can move in the front, back, left, right, up and down directions, thereby achieving an anti-collision function.

[0039] Reference Figure 1 and Figure 5In some embodiments of the present application, the face shell assembly 100 further includes a sealing ring 130, which surrounds the outer peripheral wall of the radar 120 and is arranged between the outer peripheral wall of the radar 120 and the inner peripheral wall of the radar mounting hole 111 by means of interference fit. The function of the sealing ring 130 is to prevent moisture from entering the interior of the middle shell 110, so as to avoid damage to the components inside the middle shell 110, such as the main board, when they are exposed to water. In some embodiments of the present application, the sealing ring 130 is a flexible structure. The sealing ring 130 is usually made of a flexible rubber material, so it can be arranged between the outer peripheral wall of the radar 120 and the inner peripheral wall of the radar mounting hole 111 of the middle shell 110 by means of interference fit, and has a good waterproof effect, and can effectively prevent water from flowing into the host or main board of the middle shell 110 through the radar mounting hole 111, so as to avoid damage to the components inside the middle shell 110, such as the main board, when they are exposed to water, thereby ensuring the waterproof effect of the face shell assembly 100 and ensuring the stable operation of the cleaning robot.

[0040] Further, refer to Figure 1 and Figure 6 In some embodiments of the present application, the middle shell 110 is further provided with at least one waterproof rib 113, and the at least one waterproof rib 113 includes a first waterproof rib 113a, and the first waterproof rib 113a is arranged around the radar mounting hole 111, and the first waterproof rib 113a is blocked between the groove 114 and the radar mounting hole 111 to separate the groove 114 and the radar mounting hole 111.

[0041] Specifically, since the protective cover 121 of the radar 120 is covered and buckled in the groove 114 of the middle shell 110 instead of being fixed with screws, the middle shell 110 has fewer openings, and only a small number of mounting through holes 112 are required, and the middle shell 110 is provided with at least one waterproof rib 113, the at least one waterproof rib 113 includes a first waterproof rib 113a, the first waterproof rib 113a is arranged around the radar mounting hole 111, and the first waterproof rib 113a is blocked between the groove 114 and the radar mounting hole 111 to separate the groove 114 and the radar mounting hole 111, thereby preventing it from entering the middle shell 110 through the mounting through hole 112, so as to avoid the components inside the middle shell 110, such as the main board, from being damaged by water.

[0042] Reference Figure 5 and Figure 6 In some embodiments of the present application, the face shell assembly 100 further includes a bottom shell 150, which is disposed below the middle shell 110. The middle shell 110 is provided with a drainage channel 116 connected to the drainage port 115. The bottom shell 150 is provided with a water outlet channel 151 and a water outlet 152 connected to each other. The water outlet 152 of the bottom shell 150 is connected to the drainage port 115 of the middle shell 110 through the water outlet channel 151 and the drainage channel 116.

[0043] Specifically, in the face shell assembly 100 provided in the embodiment of the present application, the middle shell 110 is recessed to form a groove 114, and the groove 114 is positioned lower than other areas of the middle shell 110. Therefore, after water flows into the middle shell 110, it will converge into the groove 114 and be discharged through the drain outlet 115. The bottom shell 150 is provided with a connected water outlet channel 151 and a water outlet 152. The water outlet 152 of the bottom shell 150 is connected to the drain outlet 115 of the middle shell 110 through the water outlet channel 151 and the drain channel 116. Therefore, the water flow entering the middle shell 110 can converge into the groove 114, and be discharged through the drain port 115, the drain channel 116, the water outlet channel 151 and the water outlet 152 of the bottom shell 150, thereby preventing the water flow from entering the middle shell 110 through the holes on the middle shell 110, and further preventing the internal components of the middle shell 110, such as the main board, from being damaged when encountering water, thereby ensuring the waterproof effect of the surface shell assembly 100 and ensuring the stable operation of the cleaning robot.

[0044] Reference Figure 6 In some embodiments of the present application, the face shell assembly 100 further includes a radar collision plate 160, on which a collision detection switch 161 is disposed, the middle shell 110 includes a first through hole 112a, the first through hole 112a is disposed in the groove 114, the collision detection switch 161 is aligned with the first through hole 112a, and at least one waterproof rib 113 includes a second waterproof rib 113b, the second waterproof rib 113b surrounds the first through hole 112a, and separates the first through hole 112a and the groove 114.

[0045] Specifically, the function of the radar collision plate 160 is to provide a buffer for the protective cover 121 to prevent the protective cover 121 from getting stuck. The radar collision plate 160 is provided with a collision detection switch 161, and the middle shell 110 is provided with a first through hole 112a. The collision detection switch 161 is aligned with the first through hole 112a so as to be able to contact the protective cover 121. At least one waterproof rib 113 includes a second waterproof rib 113b, which surrounds the first through hole 112a and separates the first through hole 112a and the groove 114. Therefore, when the water flow entering the middle shell 110 flows through the first through hole 112a, it will be blocked by the second waterproof rib 113b, so that it will not enter the inside of the middle shell 110 through the first through hole 112a, but will flow out through the drain port 115 of the groove 114. The face shell assembly 100 provided in the embodiment of the present application can prevent water from flowing into the middle shell 110 through the first through hole 112a on the middle shell 110 through the above-mentioned arrangement, so as to further prevent components inside the middle shell 110, such as a main board, from being damaged when exposed to water, thereby ensuring the waterproof effect of the face shell assembly 100 and ensuring the stable operation of the cleaning robot.

[0046] Refer again Figure 1In some embodiments of the present application, the face shell assembly 100 also includes a rear recharging light 170 and a power cord (not shown), the rear recharging light 170 is electrically connected to the power supply of the mainboard through the power cord, the middle shell 110 is also provided with a second through hole 112b, the power cord extends from the second through hole 112b, a drainage groove 117 is provided around the second through hole 112b, the drainage groove 117 is connected to the groove 114 of the protective cover 121, and at least one waterproof rib 113 includes a third waterproof rib 113c, the third waterproof rib 113c surrounds the second through hole 112b, and is arranged between the second through hole 112b and the drainage groove 117.

[0047] Specifically, the rear recharge light 170 is an infrared receiver, and the number of infrared receivers is usually two or more. The infrared light emitted by the infrared transmitter on the maintenance station can be received by the corresponding infrared receiver. The at least two infrared receivers simultaneously receive the infrared light emitted by the corresponding infrared transmitter on the maintenance station, thereby positioning the cleaning robot to move to the corresponding position of the maintenance station and perform subsequent cleaning or charging operations. The power cord is arranged between the face cover and the middle shell 120, and the rear recharge light 170 is electrically connected to the power supply on the mainboard through the power cord. In the face shell assembly 100 provided in the embodiment of the present application, the power cord extends from the second through hole 112b of the middle shell 120 and is routed directly from above the middle shell 120, thereby electrically connecting the rear recharge light 170 to the power supply on the mainboard.

[0048] In order to prevent the water flow on the middle shell 120 from flowing into the middle shell 120 through the second through hole 112b, a drainage groove 117 is provided around the second through hole 112b, and the drainage groove 117 is connected to the groove 114 of the protective cover 121. The waterproof rib 113 includes a third waterproof rib 113c, which surrounds the second through hole 112b and is arranged between the second through hole 112b and the drainage groove 117. Therefore, the water flow on the middle shell 120 can be blocked by the third waterproof rib 113c, and flows into the groove 114 through the drainage groove 117, and finally flows out through the drainage port 115. The face shell assembly 100 provided in the embodiment of the present application can prevent the water flow from entering the middle shell 110 through the second through hole 112b on the middle shell 110 through the above arrangement, so as to further prevent the components inside the middle shell 110, such as the main board, from being damaged by water, thereby ensuring the waterproof effect of the face shell assembly 100 and ensuring the stable operation of the cleaning robot.

[0049] Reference Figure 5 and Figure 6In some embodiments of the present application, the face shell assembly 100 further includes a face cover 180, a buckle (not shown) is provided at the bottom of the face cover 180, and the middle shell 110 further includes a third through hole 112c. The face cover 180 is fixed to the top of the middle shell 110 by the cooperation of the buckle and the third through hole 112c, and the waterproof rib 113 includes a fourth waterproof rib 113d, and the fourth waterproof rib 113d surrounds the third through hole 112c, and the fourth waterproof rib 113d is a double-layer structure.

[0050] Specifically, a cover 180 is provided above the middle shell 110, and the cover 180 is fixed to the middle shell 110 by means of a buckle and the third through hole 112c. The fourth waterproof rib 113d surrounds the third through hole 112c, and the fourth waterproof rib 113d is a double-layer structure, that is, since the fourth through hole 112d is far from the groove 114 of the protective cover 121, it cannot be connected with the drain port 115 in the groove 114, so the fourth waterproof rib 113d is a double-layer waterproof rib. Therefore, the cover assembly 100 provided in the embodiment of the present application can prevent water from entering the middle shell 110 through the third through hole 112c on the middle shell 110 through the above-mentioned arrangement, so as to further prevent the components inside the middle shell 110, such as the mainboard, from being damaged by water, thereby ensuring the waterproof effect of the cover assembly 100 and ensuring the stable operation of the cleaning robot.

[0051] It should be noted that if Figure 1 and Figure 6 As shown, the third through hole 112c is a through hole adjacent to the radar mounting hole 111. In fact, the number of the card holes of the face cover 180 is four. In order to prevent water from flowing into the host or mainboard of the middle shell 110 through the third through hole 112c, the third through hole 112c adjacent to the radar mounting hole 111 needs to be provided with a third waterproof rib 113c, while the other two through holes do not need to be provided with a waterproof structure because they are far away from the host or mainboard and located above the water tank.

[0052] It should be noted that, in some embodiments of the present application, the second waterproof rib 113b and the fourth waterproof rib 113d are rectangular, and the third waterproof rib 113c is U-shaped.

[0053] Specifically, in the face shell assembly 100 provided in the embodiment of the present application, the second and fourth waterproof ribs 113b and 113d, which are rectangular, can effectively prevent water from flowing into the host or mainboard of the middle shell 110 through the first and third through holes 112a and 112c, so as to avoid the components inside the middle shell 110, such as the mainboard, from being damaged by water, thereby ensuring the waterproof effect of the face shell assembly 100 and ensuring the stable operation of the cleaning robot. The power cord needs to pass through one side of the third waterproof rib 113c and be electrically connected to the rear recharge lamp 170, so the third waterproof rib 113c is U-shaped to facilitate the routing of the power cord.

[0054] Refer again Figure 5 and Figure 6 In some embodiments of the present application, the drainage channel 116 and the middle shell 110 are integrally formed. That is, the drainage channel 116 and the middle shell 110 are generally integrally injection molded by plastic material, so that production is convenient and cost-saving.

[0055] In addition, in some embodiments of the present application, at least one waterproof rib 113 is integrally formed with the middle shell 110. That is, the waterproof rib 113 and the middle shell 110 are usually integrally injection molded from a plastic material, which is convenient for production and can save costs.

[0056] Reference Figure 6 The face shell assembly 100 provided in the embodiment of the present application also includes a button assembly, which includes a button 191, a button plate 192 and a seal 193, wherein the button 191 protrudes from the button plate 192 and passes through the through hole of the face cover 180, thereby cooperating with the button set on the face cover 180, and its function is to interact with the user. The user controls the cleaning robot by pressing the button 191, such as starting, stopping, etc., and the button plate 192 is arranged between the middle shell 110 and the face cover 180, and a seal 193 is arranged around the button plate 192, and the seal 193 can prevent water from flowing into the host or mainboard of the middle shell 110 through the above through hole, so as to avoid the internal components of the middle shell 110, such as the mainboard, from being damaged by water, thereby ensuring the waterproof effect of the face shell assembly 100 and ensuring the stable operation of the cleaning robot.

[0057] The embodiment of the present application also provides a cleaning robot, including the above-mentioned face shell assembly 100. The specific structure of the face shell assembly 100 refers to the above-mentioned embodiment. Since the face shell assembly 100 adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0058] The face shell assembly 100 provided in the embodiment of the present application can ensure the waterproof effect of the sealing structure by optimizing the structure of the middle shell 110, and the installation process is simple and cost-saving.
