Description

Technical Field

[0001] This utility model relates to the field of garden machinery technology, specifically to a vision support for a lawnmower. Background Technology

[0002] As a type of garden equipment, lawnmowers move across the grass to trim lawns and other vegetation, reducing the workload of lawnmower workers and saving human resources.

[0003] Furthermore, with the development of image recognition technology, its application in real-world scenarios is becoming increasingly widespread. When integrated into lawnmowers, it enables intelligent operation, such as accurately identifying lawn boundaries and obstacles through vision, achieving automatic operation. Additionally, it allows for manual mapping and setting of virtual boundaries via control software, enabling wired operation and customized mowing modes, including zoned mowing. All of these intelligent functions of the lawnmower rely on the support of vision technology. The vision system, containing the camera, is the core component of this technology, and maintaining its operational stability is crucial for ensuring the intelligent operation of the lawnmower. Therefore, improving the stability of the vision system has become a key research direction in the industry.

[0004] Currently, existing lawnmower vision systems, such as the camera module in the adjustable position mechanism of the intelligent lawnmower camera module disclosed in patent CN218162640U, have front, left, and right brackets respectively mounted on their lens bases. These brackets house the front, left, and right cameras, forming a circular camera that simultaneously monitors the area around the lawnmower, avoiding blind spots. Therefore, the industry typically uses three cameras (front, left, and right) to achieve omnidirectional monitoring. However, considering manufacturing costs and reliability, existing lawnmowers do not use the slide rail and slider structure described in the patent for mounting the lens brackets. Instead, the three cameras are usually directly mounted on different structural components on the front and sides of the vehicle's body, and then connected to the control circuit board via wiring harnesses. Although the above structure meets the installation requirements for the front, left, and right cameras, the three cameras are independently arranged on different structural components. This means that each camera relies solely on its respective structural component for support. However, during vehicle operation, structural vibrations can affect the calibration of the three cameras, resulting in synchronization defects in their recognition and impacting the recognition performance.

[0017] The aforementioned visual support for a lawnmower includes a side support with a protruding folded edge on its side. The folded edge is formed by bending the side of the side support or by integrally casting it with the side support.

[0018] The aforementioned vision bracket for a lawnmower includes a first wire hole on the side bracket and a second wire hole corresponding to the first wire hole on the side of the central control box. The portion of the front light bracket where the left and right cameras are mounted is connected to the first wire hole at one end of the side bracket. Furthermore, the wiring of the left and right cameras passes through the first and second wire holes in sequence and is electrically connected to the control circuit board.

[0019] The positive effects of the above technical solution are:

[0025] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 3 The technical solution provided by this utility model is described in detail, but the following content is not intended to limit this utility model.

[0026] Figure 1 This is a structural diagram from one perspective of an embodiment of the visual support for a lawnmower according to the present invention. Figure 2 This is a structural diagram from another perspective of an embodiment of the visual support for a lawnmower according to this utility model. (See diagram below.) Figure 1 and Figure 2 As shown, the vision bracket for the lawnmower provided in this embodiment is used to mount a front camera 1, a left camera 2, and a right camera 3. The front camera 1, left camera 2, and right camera 3 form a vision system to achieve multi-directional image recognition and avoid blind spots. Furthermore, the vision bracket for the lawnmower provided in this embodiment includes: a central control box 4, a front connecting piece 5, and a side bracket 6.

[0027] Specifically, the intermediate control box 4 has an inner cavity, providing space for the installation of structural components. A control circuit board 43 is housed within this cavity, providing installation space for the control circuit board 43 and other structural components. The front camera 1, left camera 2, and right camera 3 are all electrically connected to the control circuit board 43, meeting the operational requirements of the vision system. Furthermore, the front camera 1 is directly mounted on the front side of the intermediate control box 4, ensuring its stability and paving the way for its subsequent placement on the same vision support as the left and right cameras 2 and 3. Additionally, the wiring of the front camera 1 is directly routed within the intermediate control box 4, resulting in better sealing and preventing moisture damage.

[0028] Specifically, side brackets 6 are installed on both sides of the central control box 4. One end of each side bracket 6 is fixedly connected to the side of the central control box 4, while the other end extends away from the central control box 4, thus extending the support distance of the central control box 4. Furthermore, the extended ends of the side brackets 6 correspond to the left camera 2 and the right camera 3, respectively. This means that the left camera 2 and the right camera 3 are also connected to the central control box 4 via the side brackets 6, thereby ensuring that the front camera 1, left camera 2, and right camera 3 are calibrated on the same visual bracket, maintaining the installation stability of the three, improving uniformity, and resulting in better visual recognition.

[0029] More specifically, a front light bracket 7 is also provided on the outer side of the central control box 4. Simultaneously, a front connecting piece 5 is provided on the front side of the central control box 4. During installation, the middle part of the front light bracket 7 is connected to the front connecting piece 5, and both ends of the front light bracket 7 are connected to the side brackets 6 respectively. At this time, the lawnmower's headlight is installed on the front light bracket 7, allowing the headlight to be supported by the vision bracket, improving the stability of the headlight after installation. Simultaneously, the front light bracket 7 connects the front connecting piece 5 and the side brackets 6 at the ends away from the central control box 4, thus further enhancing the overall effect of the vision bracket. This results in better support for the front camera 1, left camera 2, and right camera 3, thereby ensuring visual recognition performance. It is worth noting that the left camera 2 and the right camera are respectively located at the positions of the brackets 6 on both sides of the front light bracket 7. This not only meets the installation requirements of the left camera 2 and the right camera 3, but also allows the front camera 1, the left camera 2 and the right camera 3 to be installed on the integrated vision bracket composed of the middle control box 4, the two side brackets 6, the front light bracket 7 and the front connecting piece 5. This allows for better reference of the three cameras, enabling individual calibration of the components during reference verification, making it more convenient to use and more accurate in visual recognition.

[0030] Figure 3 This is an exploded view of the central control box of the vision support for a lawnmower according to this utility model. Figures 1 to 3 As shown, the intermediate control box 4 has a split structure. In this case, the intermediate control box 4 also includes a base box 41 and a cover plate 42. The cover plate 42 is detachably installed on the base box 41. Preferably, a connecting screw is provided between the cover plate 42 and the base box 41, that is, the cover plate 42 is installed on the base box 41 by the connecting screw, which facilitates the installation and removal of the cover plate 42, thereby facilitating the installation of structural components such as the control circuit board 43 in the inner cavity of the intermediate control box 4 and subsequent maintenance and repair. Furthermore, a recess 411 is provided inside the base box 41. After the cover plate 42 is closed, the recess 411 of the base box 41 forms an inner cavity for installing structural components such as the control circuit board 43, meeting the installation requirements of structural components such as the control circuit board 43.

[0031] More specifically, the cover plate 42 and / or the bottom box 41 of the intermediate control box 4 are made of a heat-conducting material. Preferably, the heat-conducting material is aluminum alloy, which can meet the requirements of efficient heat dissipation, quickly dissipate the heat generated by the control circuit board 43 and other structural components during operation, avoid high temperature affecting the operation of the control circuit and the occurrence of the control circuit burning out. At the same time, while meeting the structural strength requirements, it has a low density and light weight, reducing the burden on the lawnmower itself.

[0032] More specifically, when the cover plate 42 is made of a heat-conducting material, and in the height direction of the lawnmower, the cover plate 42 is set above the base box 41, so that the heat dissipation structure of the intermediate control box 4 is located on top of it. By taking advantage of the principle of hot air rising, the heat emitted through the cover plate 42 can be directly dissipated as hot air, avoiding the heat emitted from affecting the base box 41 which has structural components such as the control circuit board 43 installed, thus ensuring the heat dissipation effect.

[0033] More specifically, the side brackets 6 installed on both sides of the central control box 4 are also made of thermally conductive material, so that the side brackets 6 can not only support the left camera 2 and the right camera 3, but also serve as an auxiliary heat dissipation structure for the central control box 4. That is, the side brackets 6 expand the heat dissipation area of ​​the central control box 4 and further improve the heat dissipation effect.

[0034] More specifically, when selecting materials, the side bracket 6 is made of the same material as the cover plate 42 and / or the bottom box 41, which ensures material consistency, facilitates material purchase and processing, and reduces manufacturing costs.

[0035] More specifically, several raised ribs 421 can be provided on the outer wall of the cover plate 42 and / or the bottom box 41, and the several raised ribs 421 are arranged at intervals. The raised ribs 421 increase the contact area between the intermediate control box 4 and the air, that is, increase the heat exchange area and the heat dissipation effect is better.

[0036] More specifically, a protruding flange 61 is provided on the side of the side support 6. Preferably, flanges 61 are provided on both sides of the side support 6. The flanges 61 are formed by bending the side of the side support 6 or by integrally casting with the side support 6. In this case, the flanges 61 can not only be used as an auxiliary support structure to strengthen the structural strength of the side support 6, but also increase the contact area between the side support 6 and the air, thereby improving the heat dissipation efficiency and enhancing the heat dissipation effect.

[0037] More specifically, a first wire-passing hole is provided on the side bracket 6. At this point, both ends of the side bracket 6 have first wire-passing holes, facilitating wiring on the side bracket 6. Simultaneously, a second wire-passing hole corresponding to the first wire-passing hole is provided on the side of the central control box 4. Furthermore, the portions of the front light bracket 7 where the left camera 2 and right camera 3 are mounted communicate with the first wire-passing hole at one end of the side bracket 6. During installation and wiring, the wires of the left camera 2 and right camera 3 pass sequentially through the first and second wire-passing holes and are then electrically connected to the control circuit board 43. This facilitates wiring while reducing the exposed area at the wiring points, improving sealing performance. Preferably, sealing rings are selectively installed at the first and second wire-passing holes, as well as at the connection between the front light bracket 7 and the side bracket 6, achieving sealing at the wiring points and further improving airtightness to prevent moisture intrusion.

[0038] The vision bracket for the lawnmower provided in this embodiment includes a central control box 4, a front connecting piece 5, and side brackets 6. By directly mounting a front camera 1 on the front side of the central control box 4, on which the control circuit board 43 is installed, and by providing extended side brackets 6 on both sides of the central control box 4 to support the left camera 2 and the right camera 3 respectively, the front camera 1, the left camera 2, and the right camera 3 are connected to the same vision bracket where the central control box 4 is located. This achieves the calibration of the front camera 1, the left camera 2, and the right camera 3 on the same vision bracket, resulting in stronger overall connectivity, improved overall structural stability, and guaranteed visual recognition effect of the lawnmower.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
