Description

Technical Field

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

[0002] Agricultural and garden machinery includes lawnmowers, snowplows, seeders, tillers, and so on, with a wide variety of functions. Each type of machinery that performs specific gardening operations is generally designed separately and basically requires human operation and driving. Furthermore, it is difficult to use agricultural equipment interchangeably, resulting in high operating costs. With the development of unmanned technology, the applicant has proposed a garden robot. However, the front axle structure of current garden robots is relatively tall due to the limited range of rotation of the wheels mounted at both ends, making the overall garden robot tall and large, which is not conducive to the miniaturization of garden robots. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide a front axle structure for a garden robot to solve the problems of high height and limited wheel rotation of existing garden robots.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A front axle structure for a garden robot includes a garden robot body and a front axle mounted on the lower front end of the garden robot body. The middle part of the front axle is rotatably connected to the garden robot body via a horizontally arranged hinge shaft, allowing it to rotate around the hinge point in a vertical plane. A caster wheel is mounted at each end of the front axle, wherein both ends of the front axle are inclined upwards and forwards and extend. Each caster wheel includes a traveling wheel, a bracket, and a mounting base. The mounting base is vertically arranged and fixedly connected to the end of the front axle. The bracket is U-shaped, with its closed end located at the upper end and rotatably connected to the mounting base via a vertically arranged pivot shaft. Its open end is inclined towards the rear of the garden robot body and forked on both sides of the traveling wheel, and rotatably connected to the wheel axle.

[0005] As an optimization, the front axle is made of cold-bent I-beams, and multiple reinforcing ribs are provided between the two flanges of the front axle along the length of the front axle. The reinforcing ribs are fixedly connected to the two flanges and the web plate respectively.

[0006] As an optimization, two buffer pads are provided on the upper side of the middle of the front axle, located on both sides of the hinge shaft.

[0007] As an optimization, the mounting base is a cylindrical structure with the upper end closed. The lower end of the rotating shaft is fixedly connected to the bracket, and the upper end extends into the mounting base and is rotatably connected to the mounting base through a bearing.

[0008] As an optimization, the sidewall of the mounting base is fixedly connected to the end of the front axle.

[0009] As an optimization, the two ends of the front axle are located on the outside of the garden robot body, and there is a gap between the two ends of the front axle and the two sides of the garden robot body.

[0010] Compared with the prior art, the present invention has the following advantages: This utility model has a simple structure, adapts to the miniaturized design of garden robots, and improves the compactness of garden robots; the front axle is rotatably connected to the chassis of the garden robot through the central pivot, allowing the two ends of the front axle to swing up and down, making it more adaptable; the bent shape of the front axle makes the body of the garden robot low, and takes into account the rotation range of the casters, effectively avoiding the rotation range of the casters, and playing a good role in obstacle avoidance.

[0015] Example: See Figures 1-2 A front axle structure for a garden robot includes a front axle 1 mounted on the lower front side of the garden robot's body. The middle of the front axle 1 is hinged to the garden robot's body, allowing it to rotate around the hinge point in a vertical plane. This means the two ends of the front axle can swing, forming a suspension structure that enhances its adaptability to different road surfaces. A caster wheel is mounted on each end of the front axle 1. The two ends of the front axle 1 are tilted upwards and forwards, extending diagonally upwards to reduce the height of the middle section of the front axle 1, thereby reducing the overall height of the garden robot's body and making the robot's body lower and more compact.

[0016] The omnidirectional wheel includes a traveling wheel 3, a bracket 4, and a mounting base 5. The mounting base is vertically arranged and fixedly connected to the end of the front axle; the bracket is U-shaped, with its closed end located at the top and rotatably connected to the mounting base via a vertically arranged pivot; its open end is inclined towards the rear of the garden robot body and forked on both sides of the traveling wheel 3, and rotatably connected to the axle of the traveling wheel 3. In this way, the overall length of the garden robot body is shorter and the structure is more compact. Because the upper end of the bracket 4 of the omnidirectional wheel is inclined forward, the rear side of the omnidirectional wheel has a larger range of motion when rotating. Therefore, both ends of the front axle 1 bend diagonally forward; at the same time, the upward bending structure can effectively open up the range of motion of the rear side of the omnidirectional wheel, ensuring smooth steering of the omnidirectional wheel while improving structural compactness.

[0017] In implementation, the mounting base 5 is a cylindrical structure with a closed upper end. The lower end of the rotating shaft is fixedly connected to the bracket 4, and the upper end extends into the mounting base 5 and is rotatably connected to the mounting base 5 through a bearing. The side wall of the mounting base 5 is fixedly connected to the end of the front axle 1. The two ends of the front axle 1 are located on the outside of the garden robot body, and there is a gap between the two ends of the front axle 1 and the two sides of the garden robot body, which improves the connection strength and the rotation space of the universal wheels, while also improving the stability of the garden robot body.

[0018] The front axle 1 is made of cold-bent I-beams and has multiple reinforcing ribs along its length. Multiple reinforcing ribs are also installed between the two flanges of the front axle 1 along its length. These reinforcing ribs are fixedly connected to the flanges and web plate to improve the structural strength of the front axle 1. Two buffer pads 6 are located on the upper side of the middle of the front axle 1, positioned on either side of the hinge shaft 2, to reduce impact noise during swaying and extend the service life of the front axle 1.

[0019] This utility model has a simple structure, adapts to the miniaturized design of garden robots, and improves the compactness of garden robots; the front axle is rotatably connected to the chassis of the garden robot through the central pivot, allowing the two ends of the front axle to swing up and down, making it more adaptable; the bent shape of the front axle makes the body of the garden robot low, and takes into account the rotation range of the casters, effectively avoiding the rotation range of the casters, and playing a good role in obstacle avoidance.

[0020] 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.
