Description

Technical Field

[0001] This utility model relates to the field of garden machinery technology, and in particular to a rear support structure for a garden robot. Background Technology

[0002] Landscape operations encompass multiple stages, including sowing, tilling, plant protection, pruning, harvesting, weeding, and snow removal. To meet these diverse operational needs, the market has developed highly specialized machinery, such as lawnmowers for lawn mowing, snowplows for winter snow removal, tillers for land preparation, and seeders for crop planting. These machines have undergone long-term development, and their mechanical structures, power systems, and operating methods are quite mature, forming the foundation of modern agricultural and forestry production and landscape maintenance. Currently, the vast majority of equipment is still primarily operated manually, requiring operators to drive or follow the equipment to complete the tasks. Although existing specialized equipment performs well in single operational scenarios, its inherent design concepts and operating modes are no longer adequate to adapt to the new trends in modern agriculture and landscape management towards intelligence, efficiency, and low cost.

[0003] Therefore, there is a need to develop an unmanned, intelligent, and universal powertrain for garden robots. As an independent modular device, the powertrain typically requires only one walking assembly, which, together with a compatible working assembly, ultimately forms a four-wheeled or tracked garden robot. Therefore, it is necessary to ensure a certain degree of independent stability for the powertrain even without the working assembly installed. This necessitates the development of a support structure adapted to the powertrain. However, most current support structures are designed for small devices and have low support strength. For large or heavy devices like powertrains, the strength and stability requirements of the support structure are much higher, which current structures cannot meet. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide a rear support structure for garden robots, so as to solve the problems of low support strength and difficulty in meeting the stability requirements of the existing support structure.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A rear support structure for a garden robot includes a garden robot body, characterized in that: it further includes two support plates disposed on the lower rear side of the garden robot body and respectively close to both sides of the garden robot body; a support leg is rotatably disposed between the two support plates; the support leg is a rectangular frame structure formed by an upper frame, a lower frame, and two side frames, wherein the upper frame is rotatably connected to the two support plates via a pivot, and tension springs are provided between the two side frames and the support plate on the corresponding side; the lower frame of the support leg extends to both sides of the plane where the support leg is located to form an enlarged structure, and the upper frame of the support leg bends and extends to the rear side of the plane where the support leg is located to form a support portion, and a support surface is formed on the support portion; when the support leg rotates to the support position at the rear side of the garden robot body, the support surface can abut against the lower side of the garden robot body; It also includes a fixed arm installed on the underside of the garden robot body. The end of the fixed arm is provided with a snap-fit ​​plate formed by two opposing elastic plates. Correspondingly, a snap-fit ​​connector is provided on the side frame of the support leg. When the support leg rotates to the front of the garden robot body to the retracted position, the snap-fit ​​connector can snap into the snap-fit ​​plate.

[0006] Furthermore, multiple decorative grooves are spaced apart on the support part along the width direction of the garden robot body.

[0007] Furthermore, a locking mechanism is provided on the side of one support plate away from the other support plate; the locking mechanism includes a plane bearing sleeved on the rotating shaft, and a fixed block and a rotating block are provided between the plane bearing and the support plate; the fixed block and the rotating block are both sleeved on the outside of the rotating shaft, wherein the fixed block is fixedly connected to the support plate, and the rotating block is clearance-fitted to the rotating shaft, allowing it to rotate around the rotating shaft and slide along the rotating shaft, and a clamping nut is provided on the other side of the plane bearing; the rotating block is fixedly connected to a handle, wherein a first slot and a second slot are provided on the side of the fixed block and the rotating block opposite to each other, and the first slot and the second slot are transitioned by an inclined surface, and correspondingly, a locking block is provided on the rotating block; when the rotating block rotates, the locking block can move from the first slot to the second slot through the inclined surface, and in this process, the rotating block slides along the rotating shaft in the direction away from the fixed block, thereby squeezing the plane bearing, locking the plane bearing, and thus locking the support leg.

[0013] Example: See Figures 1-6 A rear support structure for a garden robot includes a garden robot body 2 and two support plates 3 disposed on the lower rear end of the garden robot body 2 and close to both sides of the garden robot body 2. A support leg 4 is rotatably disposed between the two support plates 3. The support leg 4 is a rectangular frame structure formed by an upper frame, a lower frame, and two side frames. The upper frame is rotatably connected to the two support plates 3 via a pivot. Tension springs 5 ​​are also provided between the side frames and the corresponding support plate 3. The lower frame of the support leg 4 extends to both sides of the plane containing the support leg 4 to form an enlarged structure 6, increasing the support surface area 8 and the support effect. The upper frame of the support leg 4 bends and extends to the rear side of the plane containing the support leg 4 to form a support portion 7. A support surface 8 is formed on the support portion 7. When the support leg 4 rotates to the support position towards the rear side of the garden robot body 2, the support surface 8 abuts against the lower side of the garden robot body 2, allowing the weight of the garden robot body 2 to be better transferred to the rear support frame 1 through the support surface 8, thereby increasing the support surface area 8 and the support effect.

[0014] A fixing arm 9 is provided on the lower side of the garden robot body 2, in front of the support leg 4. The end of the fixing arm 9 is provided with a snap-fit ​​plate 11 formed by two opposing elastic plates. Correspondingly, a snap-fit ​​connector 10 is provided on the side frame of the support leg 4. When the support leg 4 rotates to the front of the first body to the retracted position, the snap-fit ​​connector 10 snaps into the snap-fit ​​plate 11. In use, the rear support frame 1 rotates forward and is fixed by the snap-fit ​​structure of the fixing arm 9. This is used to fix the retracted rear support frame 1 during operation. The tension spring 5 also plays an auxiliary role in preventing the rear support frame 1 from falling. When the rear support frame 1 rotates backward to the support position, the support surface 8 on the support part 7 of the rear support frame 1 abuts against the main beam at the rear end of the first chassis, improving the support effect. In addition, multiple decorative grooves are provided on the support part 7 along the width direction of the garden robot body 2 to improve the aesthetics.

[0015] A locking mechanism is also provided on the side of one of the support plates 3 opposite to the other support plate 3. The locking mechanism includes a plane bearing 12 sleeved on the rotating shaft, and a fixed block 14 and a rotating block 15 are provided between the plane bearing 12 and the support plate 3; the fixed block 14 and the rotating block 15 are both sleeved on the outside of the rotating shaft, wherein the fixed block 14 is fixedly connected to the support plate 3, and the rotating block 15 is clearance-fitted with the rotating shaft, so that it can rotate around the rotating shaft and slide along the rotating shaft, and a clamping nut is provided on the other side of the plane bearing 12. The rotating block 15 is fixedly connected to a handle 13. A first slot 16 and a second slot 17 are provided on the side of the fixed block 14 opposite to the rotating block 15. The first slot 16 and the second slot 17 are connected by an inclined surface 18. Correspondingly, a locking block is provided on the rotating block 15. When the rotating block 15 rotates, the locking block can move from the first slot 16 to the second slot 17 via the inclined surface 18. During this process, the rotating block 15 slides along the rotation axis away from the fixed block 14, thereby squeezing the planar bearing 12 and locking the planar bearing 12, thereby locking the support leg 4.

[0016] During the use of this solution, when the powertrain (and running gear) at the rear of the vehicle body is separated from the working assembly at the front, the powertrain, having only two wheels, cannot be stably supported. In this situation, the rear support structure disclosed in this solution, with its outriggers extended and in a supported position, can stably and effectively support the powertrain, ensuring its stability when placed independently.

[0017] In summary, the rear support frame structure of this utility model adopts a frame structure, which has high strength. The expansion structure formed by the lower frame improves the support effect and stability. When retracted, the tension spring and the snap-fit ​​structure on the fixed arm improve the stability when retracted. When supported, the support surface on the support part can abut against the chassis of the garden robot's powertrain, further improving the support stability. The structure is simple and the support effect is better.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
