Tracked escape devices and vehicles

Abstract

The embodiment of the present invention discloses a crawler-type coming-out device and a vehicle. A parallelogram mechanism is taken as the basic structure, a running system serves as the auxiliary, and as a rack section of the parallelogram mechanism and a bearing framework opposite to the rack section can always be maintained in parallel, the load of the bearing framework is distributed relatively uniformly in the front and rear direction without the influence of the opening stroke. To reduce the influence on the passability of the vehicle at the folded state, a linear drive mechanism mounted on the rack is adopted, and no additional vertical space is occupied; and a third connecting piece is of a rocker structure, at the folded state, a relatively small angle is formed between the third connecting piece and the horizontal plane, and a relatively small additional vertical space is occupied, so that, generally speaking, the influence on the passability is relatively small.

Description

technical field [0001] The invention relates to a vehicle trapping device and a vehicle using the vehicle trapping device. Background technique [0002] With the improvement of living standards, the size of the urban middle class is also growing, and self-driving tours are also gradually emerging. In addition to urban roads, the routes of self-driving tours are mostly roads with relatively bad road conditions, even wild roads or places that no one has visited. Therefore, vehicle travel may face bad road conditions or no road conditions, and thus unexpected situations may occur, such that the car is trapped in muddy land, sand and gravel land. [0003] When a car is trapped in muddy or sandy ground, drivers often drive the car slowly to increase the friction between the tires and the ground to get the car out of trouble. And when can't realize getting out of trouble by this, just need to rely on external force, for example other personnel assists to promote automobile, uses...

AI Technical Summary

Problems solved by technology

Its body lifting system is only used to lift the chassis to a certain height, and then rely on the driving system to get the vehicle out of trouble. However, under this condition, the lifting of the chassis will reduce the friction between the driving system and the ground, making the vehicle in a certain position. a more serious uncontrollable state

[0005] Chinese patent document CN205344359U discloses a car tire pit self-rescue escape device with a remote control, which mainly controls the different working states of the escape device by being provided with a control mechanism and its remote control. , the passenger installs it on the tire of the motor vehicle, it cannot be directly installed on the motor vehicle, and it is driven with the vehicle

In addition, for example, the front axle of a car is an integral part of the steering system, and is usually constructed as a half shaft. The installation space of the half shaft itself is very limited, and it is not easy to realize the assembly of this type of escape device.

[0006] Chinese patent document CN105922826A discloses a trapping device roughly similar to the trapping device claimed in Chinese patent document CN205344359U, all of which need to temporarily install the trapping device on the wheel, and provide a new tire according to its radial profile larger than the tire. The support provided by CN105922826A is a number of support rods with ball heads, which cannot provide continuous support, and the ability to get out of trouble is very limited

This type of structure is simpler than the aforementioned several escape devices, but it also needs to be installed on site. If there is water accumulation at the trapped point, its installation will be very difficult

And its escape depends on the extra torsion force on a certain point (where the protrusion is located). When the trapped situation is relatively serious, it cannot provide continuous support, resulting in the failure of escape.
