[0002] A lawnmower, also known as a lawn trimmer, is a mechanical tool used to trim lawns and vegetation. Currently, there are push lawnmowers, self-propelled lawnmowers (or smart lawnmowers), etc., which can greatly reduce manual labor. When working on lawns, smart lawnmowers may sometimes encounter obstacles such as stones or walls.
[0003] Currently, smart lawnmowers are typically equipped with anti-collision plates. When a smart lawnmower encounters an obstacle and collides with it, it adjusts its angle multiple times to avoid the obstacle. However, because the smart lawnmower cannot determine the obstacle's location during the collision avoidance process, it needs to repeatedly adjust its direction to avoid the obstacle, resulting in an excessively long obstacle avoidance adjustment time. Utility Model Content
[0004] Therefore, it is necessary to provide a collision avoidance device and a smart lawnmower to address the problem of excessively long obstacle avoidance adjustment time in smart lawnmowers.
[0005] A collision avoidance device includes a collision avoidance bracket, a first conductive element and a second conductive element. The first conductive element is disposed on the collision avoidance bracket and has a plurality of conductive portions spaced apart. The second conductive element is spaced apart on the side of the first conductive element away from the collision avoidance bracket.
[0006] During a collision, the second conductive element can deform and abut against any of the conductive parts, and is electrically connected to the conductive parts.

[0009] In one embodiment, the anti-collision device further includes an anti-collision decorative strip, which is detachably connected to the anti-collision bracket, and an accommodating space is formed between the anti-collision decorative strip and the anti-collision bracket to accommodate the first conductive element and the second conductive element.
[0010] In one embodiment, the second conductive element is bonded to the anti-collision decorative strip, and both the anti-collision decorative strip and the second conductive element are flexible.
[0011] In one embodiment, the first conductive element is bonded to the anti-collision bracket;

[0014] When the second conductive element deforms and abuts against any of the conductive parts, the positive electrode harness is electrically connected to the negative electrode harness.
[0015] In one embodiment, the anti-collision device further includes a control module, wherein the second conductive element and any of the conductive parts are communicatively connected to the control module.
[0016] In one embodiment, the first conductive element includes four conductive portions, and the four conductive portions are spaced apart.
[0017] A smart lawnmower, the smart lawnmower comprising:
[0018] The machine body includes a walking mechanism and a control mechanism, the control mechanism being used to control the operation of the walking mechanism; and
[0019] As described in any of the above technical solutions, the anti-collision device has the anti-collision bracket disposed on the machine body and communicatively connected to the control mechanism.

[0029] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0030] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0031] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0033] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0034] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0035] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.
[0036] See Figures 1-3 As shown, this application provides a collision avoidance device 100, which includes a collision avoidance bracket 110, a first conductive element 120, and a second conductive element 130. The collision avoidance device 100 is used for obstacle detection. For example, if the collision avoidance device 100 is configured on a smart lawnmower 200, when the smart lawnmower 200 moves to an area with an obstacle, the collision avoidance device 100 collides with the obstacle and instructs the smart lawnmower 200 to perform a corresponding obstacle avoidance operation. Of course, in other feasible embodiments, the collision avoidance device 100 can also be configured on other equipment with obstacle avoidance requirements, such as sweepers and spreaders. This application does not limit the specific type of equipment on which the collision avoidance device 100 is configured.
[0037] A first conductive element 120 is disposed on the anti-collision bracket 110, and the first conductive element 120 has a plurality of conductive portions 121 spaced apart. A second conductive element 130 is spaced apart on the side of the first conductive element 120 facing away from the anti-collision bracket 110. That is to say, along the collision direction of the anti-collision bracket 110, the second conductive element 130, the first conductive element 120 and the anti-collision bracket 110 are arranged in a layered structure.
[0038] Specifically, during a collision, the second conductive element 130 can deform and abut against any conductive part 121, and the second conductive element 130 is electrically connected to the conductive part 121. In particular, during a collision, the second conductive element 130 in the anti-collision device 100 deforms and selectively connects to any conductive part 121 to activate the detection circuit and instruct the intelligent lawnmower 200 to perform corresponding obstacle avoidance operations.
[0039] The aforementioned anti-collision device 100, through the contact between the second conductive member 130 and any conductive part 121, since multiple conductive parts 121 are arranged at intervals and the positions of each conductive part 121 are different, can accurately determine the position of the obstacle based on the signal feedback from the conductive parts 121 at different positions while conducting the detection circuit. It can accurately avoid obstacles based on the position of the obstacle, thereby improving the obstacle avoidance accuracy and efficiency of the equipment equipped with the anti-collision device 100.
[0040] In one embodiment, see Figures 1-3 As shown, both the first conductive element 120 and the second conductive element 130 are strip-shaped structures, and their extending directions are consistent. Multiple conductive portions 121 are spaced apart along the extending direction of the first conductive element 120. For example, in this embodiment, both the first conductive element 120 and the second conductive element 130 are elongated strips, and multiple conductive portions 121 are spaced apart along the length of the elongated first conductive element 120. Thus, when the second conductive element 130 deforms during a collision and comes into contact with different conductive portions 121, the position of the obstacle can be accurately determined based on the position of the conductive portions 121, allowing for precise obstacle avoidance.
[0041] For example, the first conductive element 120 includes four conductive portions 121, which are spaced apart. The four conductive portions 121 are defined as a first conductive portion 1211, a second conductive portion 1212, a third conductive portion 1213, and a fourth conductive portion 1214, respectively, and are spaced apart along the extending direction of the first conductive element 120. Specifically, when the second conductive element 130 deforms during a collision and becomes electrically connected to the first conductive portion 1211, the second conductive element 130 and the first conductive portion 1211 activate a detection circuit to indicate that an obstacle is located approximately in front of the first conductive portion 1211. The intelligent lawnmower 200 then adjusts its position to avoid the obstacle in front of the first conductive portion 1211. When the second conductive element 130 deforms during a collision and becomes electrically connected to the second conductive part 1212, the detection circuit between the second conductive element 130 and the second conductive part 1212 is activated to indicate that the obstacle is located approximately in front of the second conductive part 1212. The intelligent lawnmower 200 then adjusts its posture to avoid the obstacle in front of the second conductive part 1212. When the second conductive element 130 deforms during a collision and becomes electrically connected to the third conductive part 1213, the detection circuit between the second conductive element 130 and the third conductive part 1213 is activated to indicate that the obstacle is located approximately in front of the third conductive part 1213. The intelligent lawnmower 200 then adjusts its posture to avoid the obstacle in front of the third conductive part 1213. When the second conductive element 130 deforms during the collision and becomes electrically connected to the fourth conductive part 1214, the second conductive element 130 and the fourth conductive part 1214 conduct the detection circuit to indicate that the obstacle is located approximately in front of the fourth conductive part 1214. The intelligent lawnmower 200 adjusts its posture to avoid the obstacle in front of the fourth conductive part 1214.
[0042] Of course, in other feasible embodiments, the number of conductive parts 121 is not limited to the four provided above, and can also be other numbers. For other numbers of conductive parts 121, they can be adapted according to the above embodiments, which will not be described in detail here.
[0043] In one embodiment, see Figure 1 and Figure 2As shown, the distance between the first conductive element 120 and the second conductive element 130 is 1.5mm to 4mm. Setting the distance between the first conductive element 120 and the second conductive element 130 within this range serves two purposes: firstly, when the second conductive element 130 collides and deforms, it can abut against either conductive part 121, preventing the distance from being too large and causing the second conductive element 130 to fail to abut against the conductive part 121 due to small deformation, thus preventing low sensing accuracy of the anti-collision device 100; secondly, it prevents the second conductive element 130 from abutting against the conductive part 121 even when subjected to minor deformation from forces other than collisions, thus avoiding misjudgment.
[0044] Specifically, the distance between the first conductive element 120 and the second conductive element 130 can be any one of 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, and 4.0mm. Of course, the distance between the first conductive element 120 and the second conductive element 130 is not limited to the specific values provided above; the distance between the first conductive element 120 and the second conductive element 130 can also be other values within the range of 1.5mm to 4mm. This application does not impose any restrictions on the specific value of the distance between the first conductive element 120 and the second conductive element 130.
[0045] In one embodiment, see Figure 1 and Figure 2 As shown, the anti-collision device 100 also includes an anti-collision decorative strip 140. The anti-collision decorative strip 140 is detachably connected to the anti-collision bracket 110, such as by snap-fit, screw connection, or other means. A receiving space 150 is formed between the anti-collision decorative strip 140 and the anti-collision bracket 110 to accommodate the first conductive element 120 and the second conductive element 130. That is to say, the anti-collision decorative strip 140 and the anti-collision bracket 110 are spaced apart, and a receiving space 150 is formed between them to realize the installation arrangement of the first conductive element 120 and the second conductive element 130.
[0046] The aforementioned anti-collision device 100 is provided with an anti-collision decorative strip 140 to beautify the appearance of the anti-collision device 100. Since the anti-collision decorative strip 140 is detachably connected to the anti-collision bracket 110, the first conductive component 120 and the second conductive component 130 can be installed or replaced by disassembling the anti-collision decorative strip 140 and the anti-collision bracket 110.
[0047] Further, see Figure 1 and Figure 2As shown, the second conductive element 130 is glued to the anti-collision decorative strip 140 to achieve the installation and fixation of the second conductive element 130 and the anti-collision decorative strip 140. Both the anti-collision decorative strip 140 and the second conductive element 130 are flexible. For example, the anti-collision decorative strip 140 can be a flexible material such as silicone or plastic, and the second conductive element 130 can be a flexible conductive material such as a conductive sheet or conductive wire. This application does not limit the specific material type of the anti-collision decorative strip 140 and the second conductive element 130. Thus, when the anti-collision device 100 comes into contact with an obstacle, the anti-collision decorative strip 140 deforms and causes the second conductive element 130 to deform accordingly, ensuring that the second conductive element 130 is electrically connected to the first conductive element 120 and conducts the detection circuit.
[0048] Further, see Figure 1 and Figure 2 As shown, the first conductive element 120 is bonded to the anti-collision bracket 110 to achieve the installation and fixation of the first conductive element 120 and the anti-collision bracket 110. The first conductive element 120 is flexible, and / or the anti-collision bracket 110 is flexible. That is, in one embodiment, the first conductive element 120 is flexible; in another embodiment, the anti-collision bracket 110 is flexible; and in yet another embodiment, both the first conductive element 120 and the anti-collision bracket 110 are flexible. If the first conductive element 120 is made flexible, when the second conductive element 130 contacts the first conductive element 120, the flexible contact between the two increases the electrical contact area between the first conductive element 120 and the second conductive element 130, thereby improving the sensing accuracy of the anti-collision device 100. Similarly, if the anti-collision bracket 110 is made flexible, it can buffer the impact force received by the anti-collision bracket 110 from obstacles, thereby ensuring the service life and reliability of the anti-collision device 100.
[0049] The first conductive element 120 can be a flexible conductive element such as a conductive sheet or conductive wire, and the anti-collision bracket 110 can be a flexible element such as silicone or plastic. This application does not restrict the specific material type of the first conductive element 120 and the anti-collision bracket 110.
[0050] In one embodiment, see Figures 1-3As shown, one of the first conductive element 120 and the conductive part 121 is provided with a positive electrode harness (not shown), and the other of the first conductive element 120 and the conductive part 121 is provided with a negative electrode harness (not shown). That is, if the first conductive element 120 is provided with a positive electrode harness, then the conductive part 121 is provided with a negative electrode harness; and if the first conductive element 120 is provided with a negative electrode harness, then the conductive part 121 is provided with a positive electrode harness. When the first conductive element 120 deforms and abuts against either conductive part 121, the positive electrode harness and the negative electrode harness are electrically connected to conduct the detection circuit. Based on the signal feedback from the conductive parts 121 at different positions, the position of the obstacle is accurately determined, enabling precise obstacle avoidance and improving the obstacle avoidance accuracy and efficiency of the intelligent lawnmower 200.
[0051] Further, see Figures 1-3 As shown, the anti-collision device 100 also includes a control module (not shown), and the second conductive element 130 and any conductive part 121 are communicatively connected to the control module. Thus, when the anti-collision device 100 contacts an obstacle, the second conductive element 130 is electrically connected to the first conductive element 120 and feeds back the electrical signal to the control module. After receiving the electrical signal, the control module controls the intelligent lawnmower 200 to perform obstacle avoidance operations.
[0052] In this embodiment, the control module can be a programmable logic controller (PLC), a micro control unit (MCU), etc. This application does not limit the specific component type of the control module.
[0053] Additionally, see Figures 1-3 As shown, this application provides an intelligent lawnmower 200, which includes a body 210 and an anti-collision device 100 as described above. The body 210 is provided with a walking mechanism 220 and a control mechanism 230, the control mechanism 230 being used to control the operation of the walking mechanism 220. An anti-collision bracket 110 is disposed on the body 210, and the anti-collision bracket 110 is communicatively connected to the control mechanism 230.
[0054] In the aforementioned intelligent lawnmower 200, during a collision, the second conductive element 130 in the anti-collision device 100 deforms and electrically connects with the conductive part 121, thereby activating the detection circuit and instructing the intelligent lawnmower 200 to operate. The control mechanism 230 then controls the walking mechanism 220 to perform corresponding obstacle avoidance operations. Through the contact between the second conductive element 130 and any of the conductive parts 121, and because multiple conductive parts 121 are spaced apart and positioned differently, the detection circuit is activated while simultaneously receiving signal feedback from the conductive parts 121 at different locations to accurately determine the obstacle's position. This allows for precise obstacle avoidance based on the obstacle's location, improving the obstacle avoidance accuracy and efficiency of the intelligent lawnmower 200.
[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0056] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
