Problems solved by technology

However, the obstacle surmounting tool of this patent has the problem of taking up a large space. If it is carried with the car, it will make the space in the car that is not ample at all more stretched; and because the support angle of the support device is fixed, there is a problem of poor adaptability during use. question

Embodiment 1

[0034] A portable obstacle clearance device, such as figure 1 As shown, including base plate 1, barrier board 2, elastic expansion and opening mechanism and angle limiting mechanism, where:

[0035] The length of the barrier board 2 is greater than the length of the bottom plate 1;

[0036] The elastic expansion mechanism is connected to one end of the base plate 1 and the barrier plate 2, and acts on the base plate 1 and the barrier plate 2, so that the base plate 1 and the barrier plate 2 expand around the end to form a V-shaped opening;

[0037] The angle limiting mechanism includes at least one limit chain 4 (preferably two limit chains 4 are provided), one end of the limit chain 4 is connected to the open end of the bottom plate 1, and the other end is connected to the barrier board 2.

[0038] In this embodiment, when the limit chain 4 is at its natural length, the angle between the limit chain 4 and the bottom plate 1 is not greater than 90°, and the orthographic proje...

Abstract

The invention relates to a portable obstacle-crossing device, which comprises a bottom plate, a barrier-crossing plate, an elastic expanding mechanism and an angle limiting mechanism, wherein, the length of the barrier-crossing plate is larger than the length of the bottom plate; The elastic expanding mechanism is connected with one end of the bottom plate and the barrier-crossing plate, and actson the bottom plate and the barrier-crossing plate, so that the bottom plate and the barrier-crossing plate are expanded around the end in a V-shaped opening shape; The angle limiting mechanism includes at least one limiting chain, one end of the limiting chain is connected to the open end of the base plate, and the other end of the limiting chain is connected to the barrier board. Compared with the prior art, the invention is convenient to carry, simple and compact in structure, strong in adaptability, low in cost, flexible in use, convenient, reliable and convenient in operation.

Description

technical field [0001] The invention relates to a vehicle obstacle-surmounting device, in particular to a portable obstacle-surmounting device. Background technique [0002] At present, due to the massive increase of motor vehicles, urban parking spaces are tight, which brings many difficulties for parking. The vacant area suitable for parking has steps (such as curbs), and most current vehicles (especially cars) cannot climb the steps due to their low chassis. Especially for novices, climbing the steps is easy to scratch the chassis. cause vehicle damage. This makes a lot of vacant land suitable for parking idle, causing unnecessary waste. [0003] Chinese patent CN204703022U discloses a simple obstacle-breaking tool for small cars, including a support device and an extension device, and the support device and the extension device can be connected by trapezoidal teeth on the support device and trapezoidal grooves on the extension device. However, the obstacle surmounting...
