Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 5, the present invention discloses an automatic walking device 100 which can be driven to do garden work, wherein the automatic walking device 100 comprises a device body 101, and a driving structure 102 mounted on the device body 101 for driving the device body 101 to walk. In the present embodiment, the self-propelled device 100 is a lawn mower, but may be other types of garden tools capable of self-propelling, and is not limited herein.

The driving structure 102 includes a power output module 10 and a traveling wheel 20 driven by the power output module 10 to drive the automatic traveling apparatus 100 to travel. The power output module 10 includes a driving shaft 11 and a driving gear 12 disposed on the driving shaft 11, and the driving gear 12 is disposed outside the apparatus body 101. The traveling wheel 20 comprises a hub 21 arranged on the outer side of the equipment body 101, and inner teeth 22 are arranged on the inner side of the hub 21.

The driving gear 12 is directly engaged with the internal teeth 22, so that the driving gear 12 can be driven to rotate by the driving shaft 11, the driving gear 12 directly drives the internal teeth 22 to rotate, and then the traveling wheel 20 is driven to rotate, and the traveling of the automatic traveling device 100 is realized. In this embodiment, the number of teeth of the driving gear 12 is less than that of the internal teeth 22, so that the rotation speed of the traveling wheel 20 can be reduced.

Compared with the prior art, the invention cancels the structure that the driving gear is meshed with the internal teeth after being subjected to speed reduction transmission through the gear box in the traditional driving structure, thereby reducing the manufacturing cost of the product, and simultaneously changes the transmission design in the field and realizes the technical innovation.

In the present embodiment, the driving gear 12 is coaxially disposed on the driving shaft 11, and the axis of the driving shaft 11 is parallel to the axis of the rotation shaft of the traveling wheel 20 and is disposed at a distance from each other. The power output module 10 comprises a pair of driving motors 13, the driving motors 13 are arranged at left and right intervals along the axial direction of the driving shaft 11, each driving motor 13 is connected with one driving shaft 11, and each driving shaft 11 is provided with one driving gear 12.

Correspondingly, the walking wheels 20 are also provided with a pair of walking wheels and are arranged on two sides of the equipment body 101 at intervals, and each walking wheel 20 is provided with internal teeth 22, so that each driving gear 12 can be meshed with the internal teeth 22 of the corresponding walking wheel 20 to drive the corresponding walking wheel 20 to walk, and power transmission is realized. In the invention, the driving motor 13 and the travelling wheels 20 are combined into one part, thus having the advantages of simplifying the installation mode, reducing the production, transportation and management costs and the like.

Compared with the technical scheme that the traditional driving motors are arranged inside the machine, the pair of driving motors 13 are arranged outside the equipment body 101, and the equipment has the advantages of convenience and flexibility in replacement. This is because: the drive motor 13 is a wear part and often needs to be removed and replaced.

As shown in fig. 2, the automatic walking device 100 further includes a control center 14 housed inside the device body 101 for controlling the operation of the driving motor 13, and a cable 15 connecting the control center 14 and the driving motor 13. The control center 14 is used for controlling the driving motor 13 to operate, thereby realizing walking, turning, etc. of the automatic walking device 100.

Further, the automatic walking device 100 further includes a battery (not shown) such as a lithium battery installed on the device body 101 to provide working energy for the driving motor 13, and of course, the automatic walking device 100 may also be powered by an external power source, which is not limited herein.

In summary, the driving structure 102 of the automatic walking device 100 of the present invention designs the driving gear 12 to be directly meshed with the internal teeth 22 of the walking wheel 20, so as to drive the walking wheel 20 to walk, which not only has the advantages of fewer parts and simple structure, but also changes the transmission design in this field, and realizes technical innovation.

Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
