[0025] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

For example, different embodiments and technical solutions can be formed by combining different specific technical features. To avoid unnecessary repetition, various possible combination methods of the various specific technical features in the present utility model will not be described separately.

It should be understood that the orientation descriptions "above", "below", "outside", and "inside" are all in the normal usage state.

[0028] It should be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising that element. "Plurality" means greater than or equal to two.

[0029] An embodiment of the present utility model provides a supplementary lighting component. The supplementary lighting component is used to be installed in the housing of a cleaning device and is used to supplement light to the obstacle recognition device in the housing. The obstacle recognition device includes a camera, a laser, a sensor, etc. For example, the supplementary lighting component supplements light to the camera by increasing the light to improve the lighting conditions in the camera shooting area, reducing the influence of shadows and low light, so that the picture taken by the camera is clearer and brighter, which helps to improve the shooting effect and image quality, and further can improve the accuracy of obstacle recognition or garbage recognition.

[0030] As Figure 1 and Figure 3 As shown, the supplementary lighting component 1 includes a circuit board 11 and a supplementary light 12. The circuit board 11 is arranged in the housing and is close to the collision part 3 on the housing. The collision part 3 is located in front of the sweeping robot. During the forward movement of the sweeping robot, the collision part 3 collides with an obstacle first, playing a buffering and protecting role. The obstacle recognition device 4 is electrically connected to the circuit board 11 and can timely transmit the information detected by the obstacle recognition device 4 to the circuit board 11, so that relevant components can make corresponding responses.

[0031] As Figure 2 shown, the supplementary light 12 can specifically be a small LED light or other types of lights. The supplementary light 12 is arranged on the circuit board 11, so the integration degree of the supplementary light 12 and other components on the circuit board 11 is higher, which is beneficial to the overall wiring and saves space. In addition to supplementing light to the obstacle recognition device 4, the supplementary light 12 also has other functions, such as playing a warning role in a low-light environment to let people notice the presence of the sweeping robot. In order to let the light of the supplementary light 12 emit, a light-transmitting hole 2 is opened on the housing or the collision part 3. The light-transmitting hole 2 can be such asFigure 2 The through hole on the collision part 3 shown may also be a notch on the housing.

[0032] Such as Figure 2 and Figure 3 As shown, an avoidance structure 111 for accommodating the obstacle recognition device 4 is provided on the circuit board 11. The shape of the avoidance structure 111 is not specifically limited in the embodiments of the present invention. For example, the avoidance structure 111 may be a notch or a hole on the circuit board 11. It can be understood that the circuit board 11 is usually a complete structure and will not be randomly provided with notches or holes. In this embodiment, in order to make the circuit board 11 closer to the collision part 3, an avoidance structure 111 is provided on the circuit board 11. The provision of the avoidance structure 111 enables the obstacle recognition device 4 to extend into the avoidance structure 111, that is, to penetrate the circuit board 11, reducing the interval between the circuit board 11 and the collision part 3 caused by the interference of the obstacle recognition device 4, so that the circuit board 11 is closer to the collision part 3. Since the supplementary light lamp 12 is provided on the circuit board 11, the supplementary light lamp 12 is closer to the collision part 3, and the light of the supplementary light lamp 12 directly shoots out from the light-transmitting hole 2 on the housing or the collision part 3, without the need to set a light guide column to guide or set an adapter wire to adjust the setting method, thereby reducing the manufacturing cost and difficulty.

[0033] The supplementary light component 1 provided in the embodiments of the present invention includes a circuit board 11 and a supplementary light lamp 12. The circuit board 11 is arranged in the housing and is close to the collision part 3 on the housing. The obstacle recognition device 4 is electrically connected to the circuit board 11. The supplementary light lamp 12 is arranged on the circuit board 11. The supplementary light lamp 12 is at least used to supplement light for the obstacle recognition device 4. A light-transmitting hole 2 for the light of the supplementary light lamp 12 to shoot out is provided on the housing or the collision part 3, and an avoidance structure 111 for accommodating the obstacle recognition device 4 is provided on the circuit board 11, so that the obstacle recognition device 4 can be located in the avoidance structure 111. In this way, the circuit board 11 is closer to the collision part 3, so that the light emitted by the supplementary light lamp 12 provided on the circuit board 11 can be directly emitted, without setting a light guide column or an adapter wire, reducing the manufacturing cost. At the same time, the light energy of the supplementary light component 1 is not easily lost, thereby improving the utilization rate of the light of the supplementary light component 1, and also enhancing the reliability of the obstacle recognition device 4 in recognizing obstacles.

[0034] In some embodiments, such as Figure 3 As shown, the circuit board 11 has a first board surface M1 facing the collision part 3, and the supplementary light lamp 12 is arranged on the first board surface M1. Specifically, in order to reduce the influence of the setting of the supplementary light lamp 12 on the circuit board 11, the supplementary light lamp 12 is arranged on the first board surface M1 of the circuit board 11 to reduce the opening of the circuit board 11, which is beneficial to maintaining the circuit stability and structural stability of the circuit board 11. At the same time, the first board surface M1 faces the collision part 3, which can also shorten the distance between the supplementary light lamp 12 and the collision part 3.

[0035] In some embodiments, Figure 2 and Figure 3 As shown, the fill light assembly 1 further includes a mounting frame 13. The mounting frame 13 is connected to the housing or the collision portion 3 so that the mounting frame 13 can be fixed inside the housing. The mounting frame 13 is used to support the circuit board 11, that is, the mounting frame 13 provides a mounting position for the circuit board 11. Accordingly, the circuit board 11 can also be fixed inside the housing.

[0036] like Figure 2 and Figure 3 As shown, the obstacle recognition device 4 is arranged on the mounting frame 13 and protrudes toward the side opposite to the light transmission hole 2, so that the obstacle recognition device 4 facing the light transmission hole 2 is as free of interference as possible, thereby being able to effectively identify obstacles in front of the light transmission hole 2. Due to the structural design of the obstacle recognition device 4 on the mounting frame 13, the circuit board 11 needs to be arranged on the side of the mounting frame 13 opposite to the light transmission hole 2. In this case, in order to make the circuit board 11 as close to the collision part 3 as possible, an avoidance structure 111 is arranged on the circuit board 11, which is used to accommodate the protruding part of the obstacle recognition device 4 when the circuit board 11 is connected to the mounting frame 13, thereby achieving the purpose of reducing the spacing distance between the circuit board 11 and the mounting frame 13.

[0037] In order to fix the circuit board 11, the embodiment of the utility model provides a mounting frame 13, and the circuit board 11 is arranged on the side of the mounting frame 13 opposite to the light-transmitting hole 2, so that the circuit board 11 can be closer to the collision part 3 without interfering with the accuracy of the recognition effect of the obstacle recognition device 4, thereby further reducing the light energy loss of the fill light 12.

[0038] In some embodiments, Figure 3 As shown, the mounting frame 13 is provided with a receiving hole 131, and the receiving hole 131 penetrates the mounting frame 13. For example, if the mounting frame 13 is a plate-shaped structure, the depth of the receiving hole 131 is equal to the thickness of the mounting frame 13. The fill light 12 is at least partially located in the receiving hole 131, which includes at least the following two situations: the first situation is that the depth of the receiving hole 131 is greater than or equal to the height of the fill light 12, and the fill light 12 is completely located in the receiving hole 131; the second situation is that the depth of the receiving hole 131 is less than the height of the fill light 12, and the fill light 12 penetrates the receiving hole 131 and extends from the receiving hole 131, that is, a part of the fill light 12 is located in the receiving hole 131, and the other part protrudes from the receiving hole 131. Among them, the height of the fill light 12 refers to the protruding height of the fill light 12 relative to the first board surface M1 of the circuit board 11. In this way, since the fill light 12 is at least partially located in the receiving hole 131, the increase in the distance between the circuit board 11 and the mounting frame 13 caused by the fill light 12 is avoided.

[0039] In the embodiment of the present utility model, by providing a receiving hole 131 in the mounting bracket 13, at least a part of the supplementary light lamp 12 is located within the receiving hole 131, thereby further reducing the distance between the circuit board 11 and the mounting bracket 13. Moreover, the supplementary light lamp 12 is also closer to the collision part 3, facilitating the light of the supplementary light lamp 12 to emit from the light-transmitting hole 2. Furthermore, the receiving hole 131 can collect and reflect the light of the supplementary light lamp 12, improving the intensity of the light emitted by the supplementary light lamp 12.

[0040] In some embodiments, as Figure 4 and Figure 5 shown, a plurality of clamping structures 132 are provided on the side of the mounting bracket 13 facing the circuit board 11. The clamping structures 132 are not limited to the buckles shown in the figure. The circuit board 11 is clamped between the plurality of clamping structures 132, and then the circuit board 11 can be limited and fixed by these clamping structures 132. Further, in order to increase the area surrounded by these clamping structures 132, these clamping structures 132 can be provided at the edges of the mounting bracket 13, specifically, the upper edge and the lower edge of the mounting bracket 13; the upper edge and the lower edge of the mounting bracket 13 are the upper edge and the lower edge of the mounting bracket 13 in the normal use state of the floor cleaning robot. When the circuit board 11 is clamped to the upper edge and the lower edge, the lower edge also plays a role in supporting the circuit board 11.

[0041] As Figure 4 and Figure 5 shown, there are at least the following two ways for the circuit board 11 to be clamped between the plurality of clamping structures 132: The first is the pressing method. Specifically, first, the projections of the board surface of the circuit board 11 and the board surface of the mounting bracket 13 are overlapped in the direction perpendicular to the circuit board 11, and then the circuit board 11 is pressed between the clamping structures 132. The second is the insertion method. Specifically, the circuit board 11 is inserted between the clamping structures 132 from the left or right side of the mounting bracket 13 as shown in the figure.

[0042] In the embodiment of the present utility model, through the arrangement of the plurality of clamping structures 132, the circuit board 11 is positioned and supported, facilitating the subsequent connection of the circuit board 11 and the mounting bracket 13 together by using threaded fasteners (such as screws).

[0043] In some embodiments, as Figure 4 and Figure 5As shown, the upper edge and the lower edge of the mounting bracket 13 are respectively provided with rib strips 133 protruding toward the circuit board 11, and the rib strips 133 extend along the upper edge and the lower edge of the mounting bracket 13 respectively. The rib strips 133 play a role in limiting the circuit board 11. Among them, the rib strip 133 on the lower edge plays a role in supporting the circuit board 11. Moreover, the setting of the rib strip 133 is equivalent to increasing the thickness of the edge of the rib strip 133, so the strength of the mounting bracket 13 is also enhanced, thereby reducing the risk of excessive deformation and damage of the mounting bracket 13.

[0044] In the embodiment of the present utility model, through the setting of the rib strip 133, it plays a role in limiting and supporting the installation of the circuit board 11; at the same time, it increases the overall strength of the mounting bracket 13 and reduces the risk of deformation and damage of the mounting bracket 13.

[0045] In some embodiments, as Figure 4 and Figure 5 shown, the rib strip 133 is connected between the clamping structure 132 and the edge of the mounting bracket 13, that is, the rib strip 133 is equivalent to the root of the clamping structure 132, thereby improving the firmness of the connection between the clamping structure 132 and the mounting bracket 13.

[0046] In some embodiments, as Figure 4 and Figure 5 shown, the obstacle recognition device 4 includes a camera 41 for recognizing obstacles. The camera 41 is connected with a first flexible flat cable 411, and the first flexible flat cable 411 is connected to the circuit board 11 or other circuit boards (such as the main circuit board inside the sweeping robot). Since the camera 41 is connected to the circuit board 11 or other circuit boards 11 through the first flexible flat cable 411, the first flexible flat cable 411 can be bent and twisted, so that the complex structure inside the sweeping robot can be avoided, which helps to realize the compact design inside the sweeping robot.

[0047] In some embodiments, as Figure 4 and Figure 5 shown, the avoidance structure 111 includes a first avoidance hole 1111. The first avoidance hole 1111 can be an exemplary through hole as shown in the figure, and the camera 41 is located in the first avoidance hole 1111. As Figure 3 and Figure 5As shown, the camera 41 is installed on the mounting bracket 13 and fixed by a snap fastener 412. Then, the snap fastener 412 is also located within the first avoidance hole 1111. In this way, both the circuit board 11 and the supplementary light 12 are closer to the mounting bracket 13 provided with the camera 41 and closer to the collision part 3. As a result, the distance from the supplementary light 12 to the light-transmitting hole 2 is short, and the use of a light guide member can be omitted. At the same time, since the camera 41 is located within the first avoidance hole 1111 of the circuit board 11, the space of the circuit board 11 can be fully utilized, improving the rationality of the overall design of the supplementary light assembly 1 and making the structure more compact and regular. Moreover, with the camera 41 located within the first avoidance hole 1111, the risk of damage to the camera 41 due to direct external collision can be reduced.

[0048] In some embodiments, as Figure 4 and Figure 5 shown, the obstacle recognition device 4 further includes a laser 42. The laser 42 is used to emit detection light, and specifically, the detection light can be laser light. The combined function of the laser 42 and the camera 41 is as follows: The laser 42 emits laser light and receives the reflected signal to determine the distance and position of an object; the camera 41 captures images of the surrounding environment to provide more detailed visual information; the host in the sweeping robot fuses and analyzes the laser data and the image data to comprehensively judge the environmental conditions and achieve more accurate navigation, obstacle avoidance, and cleaning.

[0049] Such as Figure 4 and Figure 5 shown, the laser 42 is connected with a second flexible cable 421, and the second flexible cable 421 is directly connected to the circuit board 11. Since the laser 42 and the circuit board 11 are connected through the second flexible cable 421, the second flexible cable 421 can be bent and twisted (as the second flexible cable 421 twists and extends to the right in the figure), making the structure of the laser 42 and the circuit board 11 more compact.

[0050] In some embodiments, as Figure 4 and Figure 5 shown, the avoidance structure 111 further includes a second avoidance hole 1112. The second avoidance hole 1112 can be, for example, a notch as shown in the figure, and the laser 42 is located within the second avoidance hole 1112. In this way, both the circuit board 11 and the supplementary light 12 are closer to the mounting bracket 13 and the collision part 3. As a result, the distance from the supplementary light 12 to the light-transmitting hole 2 is short, and the use of a light guide member can be omitted. At the same time, since the laser 42 is located within the second avoidance hole 1112 of the circuit board 11, the space of the circuit board 11 can be fully utilized, improving the rationality of the overall design of the supplementary light assembly 1 and making the structure more compact and regular. Moreover, with the laser 42 located within the second avoidance hole 1112, the risk of damage to the laser 42 due to direct external contact can be reduced.

[0051] In some embodiments, as Figure 3As shown, there are multiple supplementary light lamps 12, and each supplementary light lamp 12 takes the camera 41 as the center of symmetry and is distributed in pairs on the first board surface M1 of the circuit board 11. The number of accommodation holes 131 may be the same as the number of supplementary light lamps 12, and the accommodation holes 131 and the supplementary light lamps 12 can be arranged in a one-to-one correspondence. As Figure 3 shown, the number of accommodation holes 131 and the supplementary light lamps 12 may also be different. There are two accommodation holes 131 arranged with the camera 41 as the center of symmetry, and each of the supplementary light lamps 12 on the same side is within the accommodation holes 131 on the same side; for example, a single accommodation hole 131 is used to accommodate two supplementary light lamps 12, the area of a single accommodation hole 131 is 49 - 300 square millimeters, the number of supplementary light lamps 12 on one side is 1 - 4, and the horizontal distance between the supplementary light lamps 12 on both sides is 30 - 80 mm.

[0052] As Figure 3 shown, the distribution of the supplementary light lamps 12 is symmetrically distributed with the camera 41 as the center to evenly illuminate the periphery of the camera 41 and avoid uneven brightness in front of the camera 41.

[0053] In the embodiment of the present utility model, through the uniform arrangement of the supplementary light lamps 12, the periphery of the camera 41 is evenly illuminated, enabling the camera to obtain clearer and more accurate images in a low-light environment and reducing image blurring or image distortion caused by uneven light.

[0054] In some embodiments, as Figure 3 and Figure 5 shown, the supplementary light assembly 1 further includes a cover 14. The cover 14 is used to shield the mounting bracket 13 to reduce the collision between the mounting bracket 13 and the surrounding environment of the sweeping robot. The cover 14 is connected to the mounting bracket 13 through a first connecting member 141, and the first connecting member 141 can be a threaded connecting member, a buckle, etc. Among them, a light homogenizing plate through which the light of the supplementary light lamp 12 passes is provided on the cover 14, and the light homogenizing plate evenly disperses the light of the supplementary light lamp 12 in the surrounding environment of the sweeping robot. In addition, a camera hole 143 through which the camera 41 obtains images of the surrounding environment is provided on the cover 14, and a light-transmitting plate is installed in the camera hole 143. The cover 14 also has a laser hole 144 through which the detection light of the laser 42 passes, and a light-transmitting plate that transmits laser or infrared light is installed in the laser hole 144. The camera hole 143 and the laser hole 144 are provided with corresponding light-transmitting plates to enable the camera 41 and the laser 42 to work properly. Exemplarily, Figure 3 the camera hole 143 and the laser hole 144 in

[0055] As Figure 3 and Figure 5As shown in the figure, in the direction perpendicular to the circuit board 11, the cover 14, the mounting bracket 13, and the circuit board 11 are sequentially stacked. The specific installation method of the cover 14, the mounting bracket 13, and the circuit board 11 can be as follows: First, the circuit board 11 is snap-connected to the mounting bracket 13; then the mounting bracket 13 is snap-connected to the cover 14; finally, threaded fasteners are sequentially passed through the circuit board 11 and the mounting bracket 13 and thread-connected to the cover 14. In this way, the cover 14, the mounting bracket, and the circuit board 11 are connected into a compact whole.

[0056] In the embodiment of the present invention, the cover 14 is provided to protect the mounting bracket 13 and the camera 41 and the laser 42 on the mounting bracket 13. Moreover, in the direction perpendicular to the circuit board 11, the cover 14, the mounting bracket 13, and the circuit board 11 are sequentially stacked and connected into a compact whole. This whole can reduce space occupation and facilitate subsequent assembly with other components.

[0057] In some embodiments, as Figure 3 and Figure 6 shown, a second connecting member 142 is provided on the cover 14, and the cover 14 is connected to the collision part 3 through the second connecting member 142. The second connecting member 142 can be a threaded fastener, a buckle, etc. After connecting the cover 14, the mounting bracket 13, and the circuit board 11 into a whole, this whole is connected to the collision part 3 through the second connecting member 142, so as to connect the cover 14, the mounting bracket 13, the circuit board 11, and the collision part 3 into a structurally stable whole.

[0058] In the embodiment of the present invention, a floor sweeping robot is also provided. As Figure 6 shown, the floor sweeping robot includes a housing, a main body, a collision part 3, and the supplementary light assembly 1 in any of the above embodiments. The main body is arranged inside the housing; the collision part 3 is connected to the housing, and the collision part 3 is located in front of the walking direction of the main body. The collision part 3 is used to buffer the collision with an obstacle; the supplementary light assembly 1 is arranged inside the housing, and the supplementary light assembly 1 is close to the collision part 3. In this way, the distance between the supplementary light assembly 1 and the collision part 3 is short, so that it is convenient for the light of the supplementary light lamp 12 on the supplementary light assembly 1 to shoot out of the outside of the collision part 3, and a light guide member for guiding the light of the supplementary light lamp 12 to the outside of the collision part 3 can be omitted. Therefore, it is beneficial to reduce the manufacturing cost of the floor sweeping robot. At the same time, the light energy of the supplementary light assembly 1 is not easily lost, thereby improving the utilization rate of the light of the supplementary light assembly 1.

[0059] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
