Description

Technical Field

[0001] This application relates to the field of lawnmower technology, and more particularly to a lawnmower assembly unit with supplemental lighting function. Background Technology

[0002] Today, with sustained economic prosperity and a steady improvement in people's quality of life, the pursuit of ecological environment and leisure activities is becoming increasingly strong, and green concepts such as the construction of parks and residential areas are taking root in people's hearts. Lawns, as an indispensable green element in modern life, are receiving increasing attention. In garden maintenance, lawnmowers are often used for the regular trimming of lawns to maintain their appearance. With their advantages of ease of operation and neat trimming results, lawnmowers are gradually replacing manual weeding and are frequently seen in both daily life and work settings.

[0003] Lawn mowers can replace manual labor in trimming and cutting lawns by controlling the user or planning their own travel trajectory and work area. Lawn mowers are mostly recharged through charging stations, and currently, most lawn mowers use visual recognition of markings on the charging station to automatically return to the station for charging. To improve the recognition efficiency and accuracy of the lawn mowers, lighting equipment is often added to illuminate the markings, making it easier for the visual devices on the lawn mowers to recognize them. However, current technology places high demands on the brightness and power of the lighting equipment, and the improvement in marking recognition effectiveness is not significant.

[0004] Therefore, this utility model aims to provide a lawnmower assembly unit with supplemental lighting function to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the aforementioned technical problems, the purpose of this application is to provide a lawnmower assembly unit with supplemental lighting function. This unit aims to ensure the accuracy of visual component recognition and reduce the performance requirements of the lighting component by having a vision component installed on the lawnmower and a lighting component installed on the charging station work together. This reduces the cost of the lighting component and the light pollution generated by the lighting component.

[0006] To achieve the above objectives, this application provides a lawnmower assembly unit with supplemental lighting function, including a lawnmower, a charging station, a vision component, an identification component, and a lighting component. The identification component is disposed on the charging station, and the vision component is disposed on the lawnmower and configured to identify the identification component to guide the lawnmower back to the charging station.

[0007] The lighting component includes several light-emitting units, which are disposed on the charging station and evenly distributed along the outer periphery of the marking component. Each light-emitting unit is provided with a light-emitting side, which is used to emit light in all directions in a direction parallel to the marking component.

[0008] In some embodiments, the charging station includes a mounting frame and charging terminals, with the charging terminals, the signage assembly, and the lighting assembly located on the same side of the mounting frame.

[0009] In some embodiments, the mounting frame includes a enclosure and a support plate, the enclosure being disposed circumferentially along one side of the support plate;

[0010] The marking component and the charging terminal are disposed on the support plate and located inside the enclosure, and the light-emitting unit is disposed on the inner wall of the enclosure.

[0011] In some embodiments, two light-emitting units are provided, which are arranged opposite each other and located on the left and right sides of the marking component;

[0012] The side of the light-emitting unit away from the inner wall of the enclosure is designated as the light-emitting side.

[0013] In some embodiments, the marking component includes a first marking component and two second marking components, the two second marking components being symmetrically arranged on both sides of the first marking component and located below the first marking component.

[0014] In some embodiments, the charging station further includes a docking platform, with the mounting bracket disposed at one end of the docking platform and located in the forward direction of the lawnmower on the docking platform;

[0015] The lawnmower is adapted to be electrically connected to the charging terminal so that the charging station can charge the lawnmower.

[0016] In some embodiments, the identification component is configured as at least one of a reflective lattice, a QR code pattern, and a stripe pattern.

[0017] In some embodiments, the light-emitting side is provided with a plurality of uniformly distributed lamp bead elements, and each of the lamp bead elements is covered with a reflector for emitting light.

[0018] A protective lamp cover is also provided on the light-emitting side, and the protective lamp cover is provided on the outside of several of the lamp bead elements.

[0019] In some embodiments, the light-emitting unit is made of a translucent material, and the outer surface of the protective lampshade is provided with a matte frosted layer.

[0020] In some embodiments, a photosensitive element is also included, which is disposed on the charging station and electrically connected to the lighting assembly. The photosensitive element is used to acquire the intensity of ambient light in order to control the lighting assembly to turn on.

[0021] Compared with the prior art, the lawnmower assembly unit with supplemental lighting function provided in this application has the following advantages:

[0022] 1. This utility model provides a lawnmower assembly unit with supplemental lighting function. The lighting component is set on the charging station. The lighting component illuminates the marking component located on the charging station for recognition by the vision component located on the lawnmower, thereby guiding the lawnmower back to the charging station. The lighting component directly illuminates the marking component from the charging station and then reflects it onto the vision component, which can significantly reduce the light travel distance and significantly reduce the performance requirements of the lighting component, thereby reducing the cost of the lighting component and light pollution. Moreover, the light-emitting side of each light-emitting unit of the lighting component emits light in all directions parallel to the marking component, which can significantly reduce the light spots generated by the light-emitting unit illuminating the marking component, ensuring the accuracy of the vision component. Furthermore, the even arrangement of several light-emitting units can reduce the brightness difference of the light illuminating the marking component, reducing the possibility of local overexposure or underexposure affecting recognition.

[0023] 2. The present invention provides a lawnmower assembly unit with supplemental lighting function. The enclosure of the mounting frame is arranged around the support plate, and the light-emitting unit is arranged on the inner wall of the enclosure. This can reduce the diffusion of light emitted by the lighting component outside the mounting frame and further improve the illumination effect of the lighting component on the marking component.

[0024] 3. The lawnmower assembly unit with supplemental lighting function provided by this utility model has a number of LED elements on the light-emitting side. The even distribution of the LED elements can further reduce the brightness difference on the marking components and further ensure the recognition effect of the visual components. A reflector is provided on the outside of each LED element. The reflector can diffuse the light when the light is emitted from the light-emitting side of the LED element, thereby improving the illumination effect of the light on the marking components.

[0025] 4. The lawnmower assembly unit with supplemental lighting function provided by this utility model has a matte frosted layer on the outer surface of the protective lampshade, which can further disperse the light evenly and softly, and further improve the lighting effect of the lighting components.

[0026] 5. The present invention provides a lawnmower assembly unit with supplemental lighting function. The charging station is equipped with a photosensitive element that is electrically connected to the lighting component. The photosensitive element obtains the intensity of the external light and controls the lighting component to turn on supplemental lighting when the light is dim. When the light is sufficient, the lighting component is turned off to reduce power consumption, resulting in a higher degree of automation and a better user experience. Attached Figure Description

[0041] Lawn mowers can replace manual labor in trimming and cutting lawns by following user commands or planning their own movement paths and work areas. Typically, lawn mowers replenish their power at charging stations. Currently, most lawn mowers use visual recognition technology to detect markings on charging stations and automatically return to them for charging. In low-light environments, to improve the speed and accuracy of marking recognition, additional lighting devices are often added to illuminate the markings so that the lawn mower's vision system can more clearly identify them. However, in existing technology, lighting devices are mostly located on the lawn mower itself, which places stringent requirements on their performance specifications, requiring high brightness and power, but with limited improvement in the vision system's recognition capabilities.

[0042] In this embodiment, a lawnmower assembly unit with supplemental lighting function is provided (see attached instruction manual). Figures 1 to 5 Specifically, it includes a lawnmower 1, a charging station 2, a vision component, a marking component, and a lighting component. The vision component is mounted on the lawnmower 1 and is used to take photos of the lawnmower 1's working area, and is configured to recognize the marking component in the photos. Correspondingly, the marking component is mounted on the charging station 2, and the vision component can guide the lawnmower 1 back to the charging station 2 for charging by recognizing the marking component.

[0043] It should be noted that in this embodiment, an illumination component is also provided on the charging station 2. The illumination component includes several light-emitting units 41, which emit light to the outside for illumination. Several light-emitting units 41 are provided on the charging station 2 and are evenly distributed along the outer periphery of the marking component. Accordingly, each light-emitting unit 41 is provided with a light-emitting side 42. The light-emitting unit 41 emits light through the light-emitting side 42, and the light-emitting side 42 is used to emit light in all directions parallel to the marking component, so that the light emitted by the light-emitting unit 41 can illuminate the marking component.

[0044] Understandably, in this embodiment, placing the lighting component on the charging station 2, compared to placing it on the lawnmower 1, allows the lighting component to directly illuminate the marking component on the charging station 2, shortening the light propagation distance and reducing light propagation loss. This lowers the performance requirements of the lighting component; even with lower brightness and power, it can still illuminate the marking component and meet the brightness requirements for light reflected into the vision component, thereby reducing equipment costs and light pollution. Conversely, compared to placing the lighting component on the lawnmower 1, the light beam of the lighting component is generally concentrated on the marking component, which can easily create light spots, affecting the recognition of the vision component and thus affecting the smooth movement of the lawnmower. In this embodiment, the light-emitting side of the light-emitting unit 41 emits light in all directions parallel to the marking component, avoiding concentrated light and ensuring the recognition effect of the vision component.

[0045] In one embodiment, see the appendix to the specification. Figure 1 This embodiment further describes the charging station 2. The charging station 2 includes a mounting frame 22 and a charging terminal 223. The charging terminal 223, the marking component, and the lighting component are all mounted on the mounting frame 22 and located on the same side of the mounting frame 22. The lawnmower 1 moves to the charging station 2 under the guidance of the marking component through the vision component and is electrically connected to the charging terminal 223 on the charging station 2, so that the lawnmower 1 is charged through the charging station 2.

[0046] It is understandable that by placing the lighting component on the charging station 2, which can be powered by the lighting component, this embodiment provides power to the lighting component through the charging station 2, compared to placing the lighting component on the lawnmower 1. This does not affect the lawnmower 1's battery life, and placing it on the charging station 2 offers greater flexibility. The vision component can be configured as a camera and a processing unit. The camera is placed on the lawnmower 1 to take photos within the working area, and the processing unit controls the movement of the lawnmower 1 by processing the photos and recognizing the identification components.

[0047] Further, see the appendix to the instruction manual. Figure 1This embodiment further describes the charging station 2. The charging station 2 also includes a docking platform 21, with a mounting frame 22 disposed at one end of the docking platform 21. The docking platform 21 serves to support the lawnmower 1 during charging. Furthermore, the mounting frame 22 is located in the forward direction of the lawnmower 1 as it moves on the docking platform 21. Correspondingly, the marking component, lighting component, and charging terminal 223 are all located on the side of the mounting frame 22 closer to the lawnmower 1, allowing the lawnmower 1 to be electrically connected to the charging terminal 223 when it moves onto the docking platform 21, thereby charging the lawnmower 1 through the charging station 2.

[0048] Of course, in actual production applications, the docking platform 21 serves to dock the lawnmower 1. The docking platform 21 can be set up according to the actual situation. The mounting bracket 22 can be installed on the docking platform 21, or it can be set up directly on the ground.

[0049] Furthermore, the mounting frame 22 includes a enclosure 221 and a support plate 222. The support plate 222 can be vertically mounted on one end of the docking platform 21 or inclined on the docking platform 21. The enclosure 221 is arranged circumferentially along the support plate 222 and is located on one side of the enclosure 221. Correspondingly, the marking component and the charging terminal 223 are both mounted on the support plate 222 and located inside the enclosure 221, while a plurality of light-emitting units 41 are evenly arranged on the inner wall of the enclosure 221, so that the light-emitting units 41 illuminate the marking component mounted on the support plate 222.

[0050] In one embodiment, see the appendix to the specification. Figure 2 This embodiment provides a specific form of a lighting component. In this embodiment, the lighting component has two light-emitting units 41, which are arranged opposite each other and on the left and right sides of the sign component. Accordingly, the side of the light-emitting unit 41 away from the inner wall of the enclosure 221 is designated as the light-emitting side 42. The light-emitting side 42 can be arranged perpendicular to the support plate 222 so that the light-emitting side 42 emits light in all directions in a direction parallel to the support plate 222.

[0051] Furthermore, the marking component includes a first marking component 31 and a second marking component 32. There are two second marking components 32, which are symmetrically arranged on both sides of the first marking component 31 and located below the first marking component 31, so that the first marking component 31 and the two second marking components 32 are respectively located at the three vertices of the triangle.

[0052] Understandably, by placing two light-emitting units 41 correspondingly on the left and right sides of the sign component, and symmetrically arranging two second sign components 32 below the first sign component 31, the light intensity on the sign component is symmetrically distributed. Furthermore, when the light-emitting units 41 illuminate the sign component, the greater the distance from the light-emitting units 41, the smaller the difference in light intensity across an equal area. Differences in light intensity can lead to localized overexposure or underexposure, affecting the visual recognition of the component. Therefore, in actual production applications, the sign component should maintain a certain distance from the light-emitting units 41 to ensure illumination while maximizing the uniformity of light received by the sign component.

[0053] Accordingly, the marking components are configured as at least one of reflective lattice, QR code pattern, and stripe pattern. Generally, the first marking component 31 and the second marking component 32 can be selected to use different types of patterns according to actual needs. Of course, in actual production applications, the marking components can also be configured with other patterns, which will not be described in detail here. In addition, the first marking component 31 and the second marking component 32 can be configured as 3M diffuse reflective paper with the above-mentioned patterns, and the 3M diffuse reflective paper can be glued and fixed to the support plate 222.

[0054] In one embodiment, see the appendix to the specification. Figure 4 and Figure 5 This embodiment further describes the light-emitting unit 41. A plurality of LED elements 421 are disposed on the light-emitting side 42 of the light-emitting unit 41, and these LED elements 421 are evenly distributed to reduce the difference in light intensity illuminating the sign component. Correspondingly, a reflector 422 is also fitted over the outside of each LED element 421 to reflect the light from the LED element 421 forward. Preferably, the reflector 422 is in the shape of a regular pyramid, gradually increasing in size towards the inner wall away from the enclosure 221, so as to disperse and diffuse the light, reducing the possibility of light spots forming on the sign component.

[0055] Furthermore, a protective lampshade 423 is provided on the light-emitting side 42, and the protective lampshade 423 covers the outside of several lamp bead elements 421, so that the protective lampshade 423 can protect the lamp bead elements 421. In addition, the light-emitting unit 41 is made of a semi-transparent material, and the outer surface of the protective lampshade 423 is coated with a matte frosted layer, which can further uniformly disperse the light.

[0056] In one embodiment, a lawnmower assembly unit with supplemental lighting further includes a photosensitive element 5, which is electrically connected to a lighting component. The photosensitive element 5 senses the light intensity in the external environment and controls the lighting component to turn on and off based on the light intensity. It is understood that if the photosensitive element 5 senses that the light intensity in the external environment does not meet the needs of the vision component (e.g., the brightness is too low), the photosensitive element 5 can turn on the lighting component to provide supplemental lighting. When the photosensitive element 5 senses that the light intensity in the external environment meets the needs of the vision component, it controls the lighting component to turn off, reducing unnecessary waste.

[0057] In this embodiment, the lighting components can be automatically adjusted by the photosensitive element 5, eliminating the need for manual adjustment by the user, making it more convenient and flexible to use. Preferably, the photosensitive element 5 is located on the outside of the mounting bracket 22, for example, on the side of the support plate 222 away from the enclosure 221, to reduce the interference of the light from the lighting components on the photosensitive element 5 and ensure that the photosensitive element 5 obtains accurate light intensity.

[0058] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
