Description

Technical Field

[0001] The present disclosure relates to the structure of a base station for an autonomous mobile device, and more particularly to a lens and a base station including the lens. Background Art

[0002] An autonomous mobile device refers to an intelligent mobile device that autonomously performs preset tasks, and the autonomous mobile device can autonomously move on a traveling surface according to the results sensed by its sensing components. Currently, autonomous mobile devices generally include, but are not limited to, cleaning robots (such as intelligent floor sweepers, intelligent floor scrubbers, window cleaning robots), companion mobile robots (such as intelligent electronic pets, nanny robots), service mobile robots (such as reception robots in hotels, inns, meeting places), industrial inspection intelligent devices (such as power inspection robots, intelligent forklifts, etc.) and security robots (such as household or commercial intelligent guard robots).

[0003] Cooperating with the autonomous mobile device, a base station positioned on the traveling surface is usually further provided, and the base station may have a guiding system for guiding the autonomous mobile device to dock. When the autonomous mobile device finishes performing a task or needs to be charged, the guiding system can enable the autonomous mobile device to dock with the base station, and then operations such as charging the autonomous mobile device can be performed. For this purpose, the guiding system includes an infrared ray generator disposed inside the housing of the base station. Further, in order to protect the infrared ray generator while not interfering with the propagation of the infrared rays of the infrared ray generator, the housing of the base station is provided with a lens (or also referred to as a lens). The overall shape of the existing lens is a flat shape, which is not conducive to adapting to the curved outer contour shape of the housing while ensuring that the infrared rays do not distort after passing through the lens.

[0015] Satisfy 1 / 150 ≥ K1 ≥ 1 / 500 and 1 / 150 ≥ K2 ≥ 1 / 500.

[0016] In another alternative embodiment, the first contour line includes a first intermediate segment that crosses the center line, and the first intermediate segment is an elliptical arc; the second contour line includes a second intermediate segment that crosses the center line, and the second intermediate segment is an elliptical arc.

[0017] In another alternative embodiment, the part of the first contour line other than the first intermediate segment is located on a first positive circle, and the part of the second contour line other than the second intermediate segment is located on a second positive circle, and the second positive circle is concentric with the first positive circle.

[0018] In another alternative embodiment, the installation structure includes a lapping portion, a clamping portion, and a plugging portion.

[0019] A plurality of the overlapping portions are fixedly arranged on the first edge portion of the lens body and are spaced apart from each other in the width direction, and a plurality of the clamping portions are fixedly arranged on the second edge portion of the lens body and are spaced apart from each other in the width direction. The first edge portion and the second edge portion are respectively the edge portions on both sides of the lens body in its height direction.

[0020] A plurality of the plugging portions are fixedly arranged on the third edge portion and the fourth edge portion of the lens body. The third edge portion and the fourth edge portion are respectively the edge portions on both sides of the lens body in its width direction.

In addition, by arranging the mounting structure of the lens at the peripheral portion of the lens body, the lens can be firmly mounted to the base station through the mounting structure without affecting the infrared rays passing through the lens body. Moreover, it can ensure that the infrared rays of the base station will not produce undesired distortion after passing through the lens body. Further, during the later maintenance process, only the lens needs to be cleaned, and there is no need to clean the above-mentioned sensors, thereby simplifying the maintenance work.

[0044] The embodiments of the present disclosure will be described below with reference to the accompanying drawings. For ease of understanding, the elements shown in the respective drawings may include elements represented differently from the actual dimensions and scales, such as dimensions and scales.

[0045] In the present disclosure, the "width direction", "thickness direction", and "height direction" respectively refer to the width direction, thickness direction, and height direction of the lens body of the lens. After the lens is installed in the housing of the base, the height direction is the same as the vertical direction, and the infrared rays generated by the infrared ray generator of the base mainly propagate through the light-transmitting surfaces on both sides of the lens body in the thickness direction.

[0046] The lens according to the embodiments of the present disclosure will be described below with reference to the accompanying drawings of the specification.

[0047] As Figure 1A and Figure 1B shown, the lens according to the embodiments of the present disclosure includes a lens body 1 and a mounting structure 2 that are fixed to each other.

[0048] In this embodiment, the lens body 1 can be made of materials such as plexiglass. As Figure 1A and Figure 1B shown, the lens body 1 has a first light-transmitting surface 1s1 and a second light-transmitting surface 1s2. The first light-transmitting surface 1s1 and the second light-transmitting surface 1s2 are the outer surfaces of the lens body 1 and are spaced apart in the thickness direction D2 of the lens body 1. In this embodiment, both the first light-transmitting surface 1s1 and the second light-transmitting surface 1s2 are curved surfaces. Thus, the overall shape of the lens body 1 can be adapted to the curved outer contour of the housing 3 of the base station BS for the autonomous mobile device to dock and charge, and the infrared rays of the base station BS will not produce undesirable distortion after passing through the lens body 1, that is, the infrared rays propagating through the lens body 1 will not be scattered into a state that cannot be recognized and received by the autonomous mobile device. In the state where the lens LE is installed in the base station BS, the lens body 1 can cover the sensors inside the base station BS, keep the sensors clean, and reduce losses.

[0049] Furthermore, as Figure 1C and Figure 1DAs shown, the lens body 1 is axisymmetric with respect to its center line L in the width direction D1, that is, the parts of the lens body 1 on both sides of the center line L have a mirror-symmetrical structure. In this way, the structure of the lens body 1 can be simplified, which is beneficial to the large-scale industrial production of the entire lens LE. In addition, the thickness of the lens body 1 at each part (the dimension in the thickness direction D2) is the same. Since the lens body 1 has a structure with a uniform thickness distribution, it not only simplifies the optical parameter calculation process when designing the lens body 1, facilitating the design and manufacture of the lens body 1, but also helps to reduce the amplitude of the optical path change of different light rays passing through each part of the lens body 1.

[0050] Furthermore, as Figure 1F and Figure 1G shown, in a cross-section taken along the width direction D1 and the thickness direction D2 and perpendicular to the height direction D3 of the lens body 1, the first light-transmitting surface 1s1 has a first contour line, and the second light-transmitting surface 1s2 has a second contour line. In any same cross-section, the first contour line and the second contour line are parallel to each other. Here, "parallel" not only includes the geometric parallel relationship between the first contour line and the second contour line, but also includes the case where the two are approximately parallel. The above "approximately" means that within the reasonable error range recognized by those skilled in the art, the parallel relationship between the two can be determined to be established. By adopting such a structure, on the one hand, it is convenient to manufacture the lens body 1; on the other hand, it can further facilitate the infrared rays of the base station BS to pass through the lens body 1 without generating undesirable distortion.

[0051] Specifically, as Figure 1F and Figure 1GAs shown, the first contour line includes a first intermediate segment 1s11, a first left end portion 1s12, and a first right end portion 1s13. The first intermediate segment 1s11 is located between the first left end portion 1s12 and the first right end portion 1s13, and the three are connected to each other and continuous in the extending direction of the first contour line without interruption. The first intermediate segment 1s11 straddles the center line L, and the first intermediate segment 1s11 is an elliptical arc and is axisymmetric with respect to the center line L. In the width direction D1, the first left end portion 1s12 is located on the left side of the first intermediate segment 1s11, and the first right end portion 1s13 is located on the right side of the first intermediate segment 1s11. Both the first left end portion 1s12 and the first right end portion 1s13 are located on the first perfect circle, that is, the first left end portion 1s12 and the first right end portion 1s13 are an arc of the first perfect circle (the same perfect circle). Thus, the portion of the first contour line other than the first intermediate segment 1s11 is located on the first perfect circle. In addition, the second contour line includes a second intermediate segment 1s21, a second left end portion 1s22, and a second right end portion 1s23. The second intermediate segment 1s21 is located between the second left end portion 1s22 and the second right end portion 1s23, and the three are connected to each other and continuous in the extending direction of the second contour line without interruption. The second intermediate segment 1s21 straddles the center line L, and the second intermediate segment 1s21 is an elliptical arc and is axisymmetric with respect to the center line L. In the width direction D1, the second left end portion 1s22 is located on the left side of the second intermediate segment 1s21, and the second right end portion 1s23 is located on the right side of the second intermediate segment 1s21. Both the second left end portion 1s22 and the second right end portion 1s23 are located on the second perfect circle, that is, the second left end portion 1s22 and the second right end portion 1s23 are an arc of the second perfect circle (the same perfect circle). Thus, the portion of the second contour line other than the second intermediate segment 1s21 is located on the second perfect circle. In this way, at least a part of the first contour line is a positive circular arc and at least a part of the second contour line is a positive circular arc, so that at least a part of the lens body 1 is formed as a part of a positive circular ring. Therefore, the lens body 1 is formed into a segmented structure with different segments in the width direction D1, so that the lens LE can adapt to more application scenarios, and it is also beneficial to accurately process the structure of the lens body 1, and it is also beneficial to large-scale industrial production. It can be understood that for the lens body 1 with the segmented structure having different segments in the width direction D1 described above, both the first intermediate segment 1s11 and the second intermediate segment 1s21 are actually constructed to be substantially parallel. The cross-section of the lens body 1 includes the first intermediate segment 1s11 and the second intermediate segment 1s21, and the perpendicular line perpendicular to both the first intermediate segment 1s11 and the second intermediate segment 1s21 is also perpendicular to the cross-section. The first left end portion 1s12 and the second left end portion 1s22 are positive circular arcs and can actually achieve geometric parallelism with each other. The cross-section of the lens body 1 includes the entire circles where the first left end portion 1s12 and the second left end portion 1s22 are located respectively.Similarly, the first right end portion 1s13 and the second right end portion 1s23 can be geometrically parallel to each other in practice, and the cross-section of the lens body 1 includes the entire circles where the first left end portion 1s12 and the second left end portion 1s22 are located respectively.

[0052] As Figure 1A and Figure 1B shown, the mounting structure 2 is provided at the peripheral portion of the lens body 1 such that the lens LE can be mounted to the base station BS via the mounting structure 2 (see Figure 2B and Figure 2C ). Specifically, the mounting structure 2 includes a lapping portion 21, a clamping portion 22, and a plugging portion 23. A plurality of lapping portions 21 are fixedly provided at the first edge portion of the lens body 1 and are separated from each other in the width direction D1. The first edge portion is the upper edge portion of the lens body 1 in the height direction D3, and each lapping portion 21 is formed in a T shape. As Figure 1F shown, each lapping portion 21 protrudes from the first edge portion of the lens body 1 in the thickness direction D2 toward a direction away from the lens body 1, whereby the lapping portion 21 can lap on the corresponding lapped portion 311 of the housing 3 of the base station BS (see Figure 2B ). A plurality of clamping portions 22 are fixedly provided at the second edge portion of the lens body 1 and are separated from each other in the width direction D1. The second edge portion is the lower edge portion of the lens body 1 in the height direction D3, and each clamping portion 22 is formed in a flat plate shape. As Figure 1E shown, each clamping portion 22 protrudes from the second edge portion of the lens body 1 in the height direction D3 toward a direction away from the lens body 1, whereby the clamping portion 22 can be clamped to the corresponding clamped portion 312 of the housing 3 of the base station BS (see Figure 2B ). Two plugging portions 23 are respectively fixedly provided at the third edge portion and the fourth edge portion of the lens body 1, and the third edge portion and the fourth edge portion are respectively the edge portions on both sides of the lens body 1 in its width direction D1. As Figure 1F and Figure 1G shown, each plugging portion 23 is bent with respect to the lens body 1 at the third edge portion and the fourth edge portion, and protrudes in the width direction D1 toward a direction away from the lens body 1, whereby the plugging portion 23 can be inserted into the corresponding plugged portion 313 of the housing 3 of the base station BS (see Figure 2C ). In this way, by using the mounting structure 2 including the lapping portion 21, the clamping portion 22, and the plugging portion 23, it is beneficial to firmly and stably fix and mount the lens LE to the base station BS, and it does not affect the propagation of infrared rays through the lens body 1.

[0053] By adopting the above technical solution, the overall lens LE can be configured to be more conducive to adapting to the curved outer contour of the housing 3 of the base station BS. In addition, by arranging the mounting structure 2 of the lens LE at the peripheral part of the lens body 1, the lens LE can be firmly mounted on the base station BS through the mounting structure 2 without affecting the infrared rays passing through the lens body 1. Moreover, the infrared rays of the base station BS will not produce undesired distortion after passing through the lens body 1.

[0054] As Figure 2A shown, the present disclosure also provides a base station BS, which includes a lens LE and a housing 3. The housing 3 includes an upper housing 32 and a lower housing 31 that can be detachably assembled together. The upper housing 32 is located above the lower housing 31, and the lens LE is located in the lower housing 31. As Figure 2B and Figure 2C shown, the lower housing 31 is formed with a structure that cooperates with the mounting structure 2 of the lens LE. Specifically, the lower housing 31 is formed with a lapped portion 311 that cooperates with the number and structure of the lapping portions 21 of the lens LE, a clamped portion 312 that cooperates with the number and structure of the clamping portions 22 of the lens LE, and an inserted portion 313 that cooperates with the number and structure of the inserting portions 23 of the lens LE. Thus, the lens LE can be detachably mounted and fixed on the lower housing 31. In addition, as Figure 2B and Figure 2C shown, the base station BS further includes an infrared ray generator 4 located inside the housing 3 and fixed to the housing 3. The infrared ray generator 4 is located at a position corresponding to the lens LE, so that the infrared rays generated by the infrared ray generator 4 can pass through the lens LE and propagate to the outside of the base station BS. By adopting the above solution, when the lens LE according to the present disclosure is mounted on the base station BS, the components inside the base station BS, such as the infrared ray generator 4, can be effectively protected. At the same time, the infrared rays passing through the lens LE of the lens body 1 will not produce an excessive offset amount, that is, the infrared rays will not produce undesired distortion.

[0055] Since the infrared ray generator 4 is an optical sensor, it is very sensitive to the influence of dust and other foreign objects. The lens LE protects the infrared ray generator 4 inside the base station 3 and keeps it clean, greatly reducing the adverse effects of dust and other foreign objects on the sensor. In addition, it is more beneficial for later maintenance and cleaning after installing the lens LE. Only the lens LE needs to be wiped, and there is no need to deal with the infrared ray generator 4, which simplifies the maintenance work.

[0056] It should be understood that the above embodiments are merely exemplary and do not limit the present disclosure. Those skilled in the art can make various modifications and changes to the above embodiments under the teaching of the present disclosure without departing from the scope of the present disclosure. The following supplementary descriptions are made for the technical solutions of the present disclosure.

[0057] i. In the above specific embodiments, it is illustrated that the first light-transmitting surface 1s1 and the second light-transmitting surface 1s2 are respectively configured to be parallel to each other and have a segmented structure, but the present disclosure is not limited thereto.

[0058] In an alternative solution, the first light-transmitting surface 1s1 and the second light-transmitting surface 1s2 are parallel to each other, but the first light-transmitting surface 1s1 and the second light-transmitting surface 1s2 may not adopt a segmented structure. For example, the lens body 1 as a whole may be a part of a positive circular ring, the first light-transmitting surface 1s1 as a whole may be formed as a part of a first positive circular arc surface, and the second light-transmitting surface 1s2 as a whole may be formed as a part of a second positive circular arc surface. Thus, the first positive circular arc formed by the first contour line of the first light-transmitting surface 1s1 and the second positive circular arc formed by the second contour line of the second light-transmitting surface 1s2 are concentric with each other. This is also beneficial to the precise machining of the structure of the lens body 1 and is also beneficial to large-scale industrial production.

[0059] In addition, in the alternative solution described above, in order to further facilitate the infrared rays of the base station BS to pass through the lens body 1 without generating undesired distortion, let the radius of curvature of the first positive circular arc be K1 and the radius of curvature of the second positive circular arc be K2, satisfying 1 / 1000 ≥ K1 ≥ 1 / 3000 and 1 / 1000 ≥ K2 ≥ 1 / 3000; or satisfying 1 / 150 ≥ K1 ≥ 1 / 500 and 1 / 150 ≥ K2 ≥ 1 / 500. It can be understood that in the case of achieving the same purpose, different values of the curvature of each component of the first contour line and the second contour line can be made.

[0060] In another alternative solution, the first light-transmitting surface 1s1 and the second light-transmitting surface 1s2 may not be parallel.

[0061] ii. In the above specific embodiments, it is illustrated that the lens LE is provided with the mounting structure 2 including the lapping portion 21, the clamping portion 22, and the plugging portion 23, so as to be fixedly mounted with the housing 3 of the base station BS, but the present disclosure is not limited thereto. The specific structure and the setting position of the above mounting structure 2 can be changed according to needs, as long as the lens LE can be firmly and stably fixedly mounted on the housing 3 of the base station BS and does not affect the infrared rays passing through the lens body 1.

[0062] iii. It can be understood that in the present disclosure, the autonomous mobile device can move autonomously according to a control scheme preset in its processing unit. The traveling surface on which the autonomous mobile device moves autonomously can be a plane or a curved surface with a relatively large radius of curvature. Typically, for example, it is the floor in each room of a building. The base station BS can be fixedly arranged at any appropriate position on the traveling surface. By using the infrared ray generator 4 of the base station BS and the infrared receiver provided on the autonomous mobile device, the autonomous mobile device can dock with the base station BS according to a preset program and perform operations such as charging. In addition, in order to achieve the autonomous movement of the autonomous mobile device, the autonomous mobile device according to the present disclosure may further include a wheel assembly. The wheel assembly can be installed on the main body and protrude relative to the bottom surface of the main body, and is used to drive the entire autonomous mobile device to travel on the traveling surface under the control of the processing unit. By rotating the wheels (drive wheels) of the two wheel assemblies at the same speed in the same direction (for example, rotating clockwise at the same time or rotating counterclockwise at the same time), the autonomous mobile device can be driven to perform a linear motion along the forward movement direction; by rotating the drive wheels of the two wheel assemblies at different speeds and / or in different directions (for example, one drive wheel rotates clockwise while the other drive wheel rotates counterclockwise), the autonomous mobile device can be driven to perform a steering motion along a direction different from the forward movement direction. The autonomous mobile device may further include a caster wheel provided on the main body, so that the caster wheel can support the entire autonomous mobile device regardless of how the drive wheels roll on the surface to be cleaned. In the case where the autonomous mobile device according to the present disclosure is a self-mobile cleaning device, the autonomous mobile device may further include a dry cleaning component and a wet cleaning component. The dry cleaning component is provided on the main body and may include a main brush, a side brush (edge brush), a suction device, etc. The wet cleaning component is provided on the main body and may include a rag and a water tank, etc. Thus, when the autonomous mobile device travels on the traveling surface, the traveling surface can be cleaned by the dry cleaning component and / or the wet cleaning component. In different working modes, the cleaning operations achieved by the autonomous mobile device include, but are not limited to, one or more of operations such as sweeping, mopping, and vacuuming.
