Problems solved by technology

However, the wheels under the existing design still have no measures to prevent rolling. Only some reversing radars, body probes, etc. are installed to reduce the active alarm in the blind area of ​​vision. However, after all, there are people driving, and there are always negligence and misuse Failure to respond in time, failure of components and other unavoidable accidents, once they occur, will easily cause crushing accidents, which is very dangerous
To this day, traffic accidents caused by wheel crushing still occur around the world, and they cannot be effectively avoided.

Embodiment 1

[0023] See figure 1 As shown, in this embodiment, the moving part adopts a pin shaft 1 with a torsion spring, and the blocking part is a rear flip-type baffle plate 2 that is installed on the pin shaft 1 with a torsion spring and can be lifted backwards to open and reset. . Certainly, a plurality of grid grooves can be provided on the baffle plate. Under normal circumstances, when the baffle plate hangs down, some small objects that do not affect normal driving, such as stones, can leak through. At this time, if the force is less than the set value, the baffle will keep blocking to avoid direct contact with the wheel, and the rear lift baffle 2 will push the object forward, which can prevent people and other objects from touching the wheel instantly and the driver cannot respond or not notice it. Cause unavoidable rolling accident, also can add alarm system certainly, after the stopper touches object and does not carry out opening action, send alarm and remind driver to stop...

Embodiment 2

[0025] See figure 2 As shown, the difference between this embodiment and Embodiment 1 is that: the moving part is a pin shaft 1 with a torsion spring, and the blocking part is a pair of straddle wheels that are installed on the pin shaft 1 and can be lifted backwards to open and reset. Side baffles 4, the distance between the two-span wheel-type side baffles 4 is slightly larger than the width of the wheel, when the force is greater than the set value, the two-span wheel-type side baffles 4 are lifted backward and from both sides of the wheel for the wheel Pass by, reset by torsion spring action equally. This embodiment is applicable to the very little car model of wheel front and rear space, is particularly suitable for the steerable front wheel, avoids that object directly contacts with wheel side when turning (see Figure 8 , Figure 9 ).

Embodiment 3

[0027] See image 3 As shown, the difference between this embodiment and Embodiment 1 is that the moving part includes a pin shaft 1 with a torsion spring 7 and a sleeve arranged outside the pin shaft 1, a rotation groove is opened on the sleeve, and the stopper is One end is installed on the pin shaft 1. When the force is greater than the set value, the side-rotating baffle plate 6 can be rotated upwards along the rotation groove to open, and reset by the torsion spring 7. This embodiment is suitable for vehicles with higher chassis and larger chassis space.

Abstract

The invention discloses a rolling-free isolating device for a wheel. The rolling-free isolating device for the wheel is used for stopping direct contact between an object and a wheel in the wheel advancing direction by being arranged in front of, behind or on the side of the wheel and is used for automatically realizing continuous stopping or opening according to a stress condition; and that is tosay that the rolling-free isolating device is kept in a stopping state when the stress is less than a set value and the rolling-free isolating device is opened for the wheel to pass when the stress is larger than the set value; therefore, people or other objects needing to be stopped can be reliably and effectively prevented from getting under the wheel to suffer rolling injury; and for objects which can pass steps and so on, the rolling-free isolating device can be opened for the wheel to pass without hindering the normal running of a vehicle.

Description

technical field [0001] The invention relates to foundation pit support technology, more specifically, to a wheel-rolling-free isolation device. Background technique [0002] With the development of society, there are more and more vehicles, and traffic accidents are also increasing. A large part of them are accidents that cause disability or death due to wheel crushing, especially when the vehicle is running at low speed, reversing, etc. During non-high-speed driving where traffic accidents should occur, rolling accidents continue to occur due to reasons such as blind spots, negligence, and accidents. However, the wheels under the existing design still have no measures to prevent rolling. Only some reversing radars, body probes, etc. are installed to reduce the active alarm in the blind area of ​​vision. Various unavoidable accidents such as untimely response, component failure, etc., once they occur, it is easy to cause a rolling accident, which is very dangerous. To this...
