[0002] At present, garden robots are widely used in large-scale snow removal, mowing and other work to greatly improve work efficiency. During the mobile work of the garden robot, if there is an obstacle in front of it, there is a problem that the garden robot collides with the obstacle, causing the obstacle to be drawn into the inside and the garden robot to be damaged.

[0035] Combination Figures 1 to 5 As shown, the present application protects a garden robot 10, which includes a functional component 100 and a protective component 200. For the functional component 100, establish Figure 1 In the rectangular coordinate system shown, the X-axis represents the moving direction of the functional component 100, the Y-axis represents the width direction of the functional component 100, and the Z-axis represents the vertical direction. Further, the positive direction of the X-axis is the front side of the functional component 100, the negative direction of the X-axis is the rear side of the functional component 100, the positive direction of the Y-axis is the left side of the functional component 100, the negative direction of the Y-axis is the right side of the functional component 100, the positive direction of the Z-axis is the top, and the negative direction of the Z-axis is the bottom. In addition, the functional component 100 has a functional cavity 110, and a functional component 130 is arranged in the functional cavity 110. Specifically in the illustrated embodiment, the functional component 100 is a snow-sweeping component, and the functional component 130 is a snow-removing impeller. The protective component 200 is arranged on the front side of the functional component 100. In other embodiments, the functional component 200 can also be one or more of a mowing component, a leaf blowing component, a roller brush component, and a salt spreading component.

[0036] It can be understood that when the garden robot 10 is moving along the positive direction of the X-axis, when there is an obstacle in front, the protective component 200 can play a blocking role on the front side of the functional component 100 to prevent the obstacle from being drawn into the functional cavity 110, thereby protecting people or small animals. At the same time, it can also prevent other types of solid obstacles from being drawn into the functional cavity 110 and causing damage to the mechanical structure located in the functional cavity 110, so that the garden robot 10 has a better protective effect.

[0037] Specifically, the protection component 200 includes a plurality of protection bars 210, and the plurality of protection bars 210 are connected to the front side of the functional component 100. Among the plurality of protection bars 210, an inlet 220 extending in the width direction is formed between any two adjacent protection bars 210, and the plurality of inlets 220 are arranged in sequence at intervals in the vertical direction. The inlet 220 is connected to the functional cavity 110.

[0038] It can be understood that, since an inlet 220 is formed between the multiple protection strips 210, the snow to be removed enters the functional cavity 110 through the inlet 220 and is cleaned, so that the multiple protection strips 210 will not constitute an obstacle to the cleaning of the snow, ensuring the smooth operation of the garden robot 10. Further, by forming an inlet 220 extending in the width direction between two adjacent protection strips 210, and the multiple inlets 220 formed by the multiple protection strips 210 are arranged in sequence from top to bottom in the vertical direction, in this way, when the garden robot 10 is moving and removing snow, the multiple protection strips 210 can first contact the snow, and cut the snow into multiple layers in the thickness direction of the snow, thereby facilitating the snow to smoothly pass through the inlet 220 and enter the functional cavity 110.

[0039] In some embodiments, the protection strip 210 includes a main body 211 and two connecting parts 212 connected to the functional component 100 , the main body 211 is connected between the two connecting parts 212 , and any two adjacent protection strips 210 form an inlet 220 at least between the main bodies 211 .

[0040] Combination Figure 1 and Figure 2 As shown, specifically in the present application, the protection strip 210 is strip-shaped, and the two connecting parts 212 and the main body 211 together form a U-shaped structure, so that any two adjacent protection strips 210 are completely separated in the vertical direction to form an inlet 220, that is, part of the inlet 220 is located between the main bodies 211 of the two adjacent protection strips 210 and plays a major role in letting in snow in the moving direction toward the garden robot 10, while part of the inlet 220 is located between the connecting parts 212 of the two adjacent protection strips 210 and plays an auxiliary role in letting in snow in the width direction. In other embodiments, the connecting parts 212 of multiple protection strips 210 can also be connected together without gaps, and the main bodies 211 of multiple protection strips 210 are only arranged at intervals in the vertical direction to form multiple inlets 220. In this case, the inlet 220 only plays a role in letting in snow in the moving direction toward the garden robot 10.

[0041] Combination Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in some embodiments, the main body 211 of all the protection strips 210 is located on a curved surface S, and at least among the plurality of protection strips 210 at a low position, the projection of any main body 211 at a high position in the moving direction is located in front of the projection of the main body 211 at a low position adjacent thereto. Such an arrangement can make the main body 211 at a high position and relatively forward in the moving direction preferentially contact the upper snow layer, while the main body 211 at a low position and relatively backward in the moving direction contact the lower snow layer later during the operation of the garden robot 10. In this way, the main body 211 at a high position and relatively forward in the moving direction can preferentially cut and layer the upper snow layer, so that the upper snow layer preferentially enters the functional cavity 110, thereby helping to reduce the load of the lower snow layer, so as to facilitate the main body 211 at a low position and relatively backward in the moving direction to cut and layer the lower snow layer, so as to facilitate the snow to smoothly enter the functional cavity 110 through the inlet 220.

[0042] Specifically, in the present application, the main bodies 211 of all the protection strips 210 are located on a curved surface S, and the curved surface S includes a plane segment S1 and a curved surface segment S2. The plane segment S1 is perpendicular to the moving direction, and the curved surface segment S2 is connected to the plane segment S1 and extends in a curved direction from the front side to the rear side. Among all the protection strips 210, the main bodies 211 of a part of the multiple protection strips 210 are located on the plane segment S1, and the main bodies 211 of another part of the multiple protection strips 210 are located on the curved surface segment S2. By making the plane segment S1 closer to the front than the curved surface segment S2, the multiple main bodies 211 located on the plane segment S1 are preferentially cut and layered for the upper layer of snow, while the multiple main bodies 211 located on the curved surface segment S2 are relatively later cut and layered for the lower layer of snow.

[0043] Furthermore, the projections of the multiple main bodies 211 located in the plane segment S1 in the moving direction overlap, so that during the operation of the garden robot 10, the multiple main bodies 211 located in the plane segment S1 simultaneously cut and layer the snow. The projections of the multiple main bodies 211 located in the arc segment S2 in the moving direction do not overlap, and the projections of the main bodies 211 in the high position are all located in front of the projections of the adjacent main bodies 211 in the low position, so that during the operation of the garden robot 10, among the multiple main bodies 211 located in the arc segment S2, the main bodies 211 in the high position have priority over the main bodies 211 in the low position to cut and layer the snow.

[0044] In other embodiments, the plane segment S1 may be omitted, and all the main bodies 211 may be located on the arc segment S2 and arranged in a direction gradually from the front to the rear from top to bottom, so that in any two adjacent protective strips 210, the projection of the main body 211 in a higher position in the moving direction is located in front of the projection of the adjacent main body 211 in a lower position.

[0045] In the present application, in the vertical direction, the height H1 of the plane segment S1 is greater than the height H2 of the arc segment S2, so that the multiple main bodies 211 located in the plane segment S1 are responsible for cutting and stratifying the thicker upper snow, while the multiple main bodies 211 located in the arc segment S2 are responsible for cutting and stratifying the thinner lower snow. Such a configuration can help the multiple main bodies 211 located in the arc segment S2 to cooperate in cutting and stratifying the lower snow with greater hardness, effectively reducing the risk of deformation of the protective strip 210.

[0046] In some embodiments, the distance between the main bodies 211 of any two adjacent protection strips 210 is D, and 36 mm ≤ D ≤ 40 mm. It can be understood that if the distance D between the main bodies 211 of two adjacent protection strips 210 is set larger, it is easy to cause obstacles to enter the functional cavity 110 through the inlet 220 and the protection effect is poor, while if the distance D is set smaller, it is not conducive to the smooth entry of snow into the inlet 220. By setting the distance D to 36 mm to 40 mm, it can achieve a better protection effect while facilitating the smooth passage of snow through the inlet 220.

[0047] In the present application, the distance D between the main bodies 211 of any two adjacent protection strips 210 is 38 mm, that is, for all protection strips 210, the main bodies 211 are arranged at equal intervals, and the intervals are all approximately 38 mm. In other embodiments, the intervals between the main bodies 211 may also be unequal.

[0048] Combination Figures 1 to 3 Specifically, in the present application, the protective component 200 includes two connecting side plates 230, and the two connecting side plates 230 are respectively connected to the two sides of the functional component 100 along the width direction, and the two connecting parts 212 are connected to the two connecting side plates 230 in a one-to-one correspondence. By setting the connecting side plates 230, after the connecting side plates 230 are connected to the functional component 100, the required connecting positions can be set for the connecting side plates 230 according to the connection requirements of the connecting parts 212, so as to connect the connecting parts 212 to the connecting side plates 230. In this way, the connecting parts 212 can be connected to different connecting positions. At the same time, when the connecting positions on the connecting side plates 230 are worn, only new connecting side plates 230 need to be replaced. Compared with the method of directly connecting the connecting parts 212 to the functional component 100, the setting of the connecting side plates 230 can reduce the maintenance cost and improve the speed of connection with the connecting parts 212.

[0049] In the present application, one end of the connecting portion 212 away from the main body 211 has two parallel connecting surfaces 213 in the width direction and is flat in structure, and the connecting surface 213 can fit the connecting side plate 230. The protective assembly 200 includes a threaded connector 240, and the threaded connector 240 penetrates the connecting side plate 230 and the connecting surface 213 to relatively fix the connecting side plate 230 and the connecting portion 212. Specifically, the connecting side plate 230 is provided with a first connecting hole 231 through it, and the connecting portion 212 is provided with a second connecting hole 214 at the connecting surface 213, and the threaded connector 240 penetrates the first connecting hole 231 and the second connecting hole 214, so as to stably connect the connecting side plate 230 and the connecting portion 212 together. The connection surface 213 is provided with a plurality of second connection holes 214, and the connection side plate 230 is provided with a plurality of first connection holes 231. By providing a plurality of second connection holes 214 and a plurality of first connection holes 231, it is possible to select the second connection holes 214 and the first connection holes 231 for matching according to the location setting requirements of the main body 211. Alternatively, a plurality of second connection holes 214 may be provided one by one through a plurality of threaded connectors 240 to connect a plurality of positions of the connection portion 212 with the connection side plate 230, thereby improving the connection strength between the connection portion 212 and the connection side plate 230.

[0050] Combination Figures 1 to 3 Specifically, in the present application, the functional assembly 100 includes a housing 120, the housing 120 encloses a functional cavity 110, a functional component 130 is accommodated in the functional cavity 110, and a plurality of protective strips 210 are connected to the housing 120 and are located in front of the functional component 130. The snow entering the functional cavity 110 from the inlet 220 can be swept off the ground by the functional component 130, and the snow swept off the ground can enter the body 300 of the garden robot 10 through the pipe. Specifically, the threaded connector 240 penetrates one side of the housing 120 along the width direction and the connecting side plate 230, thereby stably connecting the connecting side plate 230 to the housing 120.

[0051] In the present application, the garden robot 10 includes a body 300, which is connected to the rear side of the functional component 100. The body 300 has a power device (not shown) built in for the movement of the entire garden robot 10, and is also provided with a collection chamber (not shown) for collecting snow, grass, leaves and other collectibles.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0053] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
