Embodiment Construction

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0031] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations...

Abstract

The invention provides a vibration-damping chassis structure, a vibration damping device and a wheelchair. The vibration-damping chassis structure comprises a frame, a front wheel assembly, a middle wheel assembly, a rear wheel assembly, a first vibration damping assembly for reducing vibration of the front wheel assembly, a connecting rod structure and a second vibration reduction assembly for reducing vibration of the rear wheel assembly. The frame is rotatably connected with the front wheel assembly, and the front wheel assembly, the first vibration damping assembly, the connecting rod structure and the middle wheel assembly are sequentially connected. The frame is rotatably connected with the middle wheel assembly, and an elastic piece enabling the middle wheel assembly to move up anddown is connected between the frame and the middle wheel assembly. The frame is rotatably connected with the rear wheel assembly, and the second vibration damping assembly is connected between the frame and the rear wheel assembly. According to the vibration damping chassis structure, the vibration damping device and the wheelchair, in different use scenes, the front wheel assembly can be independently subjected to vibration damping or is in linkage with the middle wheel assembly to avoid vibration, so that the vibration damping device is higher in vibration damping capacity and can be suitable for different bumping conditions.

Description

technical field [0001] The invention belongs to the technical field of vibration reduction, and more specifically relates to a vibration reduction chassis structure, a vibration reduction device and a wheelchair. Background technique [0002] At present, there are many kinds of electric wheelchairs. From the number of tires, they are mainly divided into two categories: four-wheel electric wheelchairs and six-wheel electric wheelchairs. [0003] A four-wheeled electric wheelchair means that when driving normally, there are four tires rolling on the road, divided into two pairs of wheels, one set is the driving wheel, and the other is the driven wheel, that is, a front-drive wheelchair or a rear-drive electric wheelchair. Most of these wheelchairs have no vibration-absorbing structure, and a few products are designed with a vibration-absorbing structure at the driving wheel, and there is no vibration-absorbing structure at the driven wheel. [0004] A six-wheeled electric whe...
