Abstract
The utility model discloses a safety steering wheel of an automobile. The safety steering wheel of the automobile comprises a disk face and a steering shaft, wherein three detachable disk arcs on the disk face are connected through fixed sleeved rings, and the disk arcs and a central support are connected through detachable screws. A buffering groove which penetrates through the side wall is formed in the side wall at one end of a sleeve of the steering shaft, a guiding screw is installed on an input shaft through the buffering groove to enable the input shaft and the sleeve to be assembled together, the other end of the sleeve is fixed on an output shaft, and a spring is installed inside the sleeve. The central support on the disk face is assembled on the input shaft of the steering shaft. The safety steering wheel of the automobile can effectively reduce the pressure on a driver by the collision. When the driver is clamped in an accident, the driver can contract the steering wheel so as to increase the space among the chest and the stomach of the driver and the steering wheel, the driver can be evacuated from a cockpit in time, and damage to the driver after the accident is reduced. The safety steering wheel of the automobile is simple in structure, low in cost, comprehensive in functions, and suitable for various automobiles.
Description
Technical field
The utility model belongs to the traffic safety technical field, is specifically related to a kind of vehicle steering.
Background technology
Along with the continuous increase of global automobile quantity, the number of arteries of communication injures and deaths is also constantly increasing.China has the automobile in the whole world 3%, and the traffic death rate was up to global 16%, the continuous ten years whole world first! And wherein because untimely cause afterwards of rescue dead accounted for 70%～80%, therefore salvage work after vehicle safety performance and the traffic accident is had higher requirement.
In the automobile collision procedure, often because impact is excessive, causes operator's compartment distortion, driver to be blocked by bearing circle and make chaufeur can't save oneself to break away from that scene and salvage work are untimely etc. causes afterwards that death improves greatly.At the higher lorry of incident rate, along with the continuous pursuit to profit, lorry more and more adopts cab over type now, and simultaneously, lorry bearing circle aspect lacks corresponding safety measure (such as safety air bag in the car and so on), so potential safety hazard is more outstanding.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model is, a kind of collapsible detouchable high-safety steering wheel is provided.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
A kind of high-safety steering wheel comprises card and steering shaft, and card comprises three detouchable dish arcs and center frame, by fixedly lasso is continuous, links to each other by the detouchable screw between dish arc and the center frame between three detouchable dish arcs; Steering shaft comprises input shaft, output shaft, sleeve pipe and spring, sidewall at sleeve pipe one end offers the dashpot that connects sidewall, guider screw is installed on the input shaft by dashpot input shaft and sleeve pipe is assembled together, the other end of sleeve pipe is fixed on the output shaft, spring is installed in the sleeve pipe, one end and the input shaft of spring join, and the other end and the output shaft of spring join; The center frame of card is assemblied on the input shaft of steering shaft.
The utility model can effectively reduce the pressure that in the collision chaufeur is caused, under the situation that chaufeur in the accident is being stuck, chaufeur can in time be withdrawn out from driving compartment by the shrinkage direction dish to increase the space between chaufeur chest belly quilt and bearing circle, reduces to injure afterwards.The utility model is simple in structure, and cost is low and complete function is applicable to various vehicles.
Description of drawings
Fig. 1 is integral structure scheme drawing of the present utility model.
Fig. 2 is the structural representation of card.
Fig. 3 is the structural representation of steering shaft.
Fig. 4 is the impulsive force that bears of spring and the graph of relation of deflection.
The implication of each label is among the figure: 1-coils arc, the 2-center frame, and 3-is lasso fixedly, 4-screw, 5-input shaft, 6-output shaft, 7-sleeve pipe, 8-spring, 9-guider screw, 10-dashpot.
Below in conjunction with drawings and Examples particular content of the present utility model is done explanation in further detail.
The specific embodiment
Below provide specific embodiment of the utility model, need to prove that the utility model is not limited to following specific embodiment, all equivalents of doing on present techniques scheme basis all fall into protection domain of the present utility model.
Defer to technique scheme, as Fig. 1, Fig. 2 and shown in Figure 3, a kind of high-safety steering wheel, comprise card and steering shaft, it is characterized in that, card comprises between three detouchable dish arcs 1 and 2, three detouchable dishes of the center frame arc 1 by fixing lasso 3 and linking to each other, and is continuous by detouchable screw 4 between dish arc 1 and the center frame 2; Steering shaft comprises input shaft 5, output shaft 6, sleeve pipe 7 and spring 8, sidewall at sleeve pipe 7 one ends offers the dashpot 10 that connects sidewall, guider screw 9 is installed on the input shaft 5 by dashpot 10 input shaft 5 and sleeve pipe 7 is assembled together, the other end of sleeve pipe 7 is fixed on the output shaft 6, spring 8 is installed in the sleeve pipe 7, one end and the input shaft 5 of spring 8 join, and the other end of spring 8 and output shaft 6 join; The center frame 2 of card is assemblied on the input shaft 5 of steering shaft.
Concrete application process, when traffic accident takes place, be out of shape at operator's compartment, under the situation that chaufeur is blocked by bearing circle, chaufeur oneself when rescue (or rescue group) can be very easily removes fixing lasso 30, and detachable screw 4 is pulled down, and makes center frame 2 shrink 60mm inwards, increase the driver activity space with this, reach the purpose of timely rescue with this.In addition, when collision happens, because huge force of inertia effect, chaufeur both arms or Body contact are after card, spring 8 is compressed, play certain buffer action, so just can effectively alleviate automobile chaufeur when burst accident and be subjected to the rigid injury of bearing circle and be extruded the deadly phenomenon of causing injury, guarantee the chaufeur life security to greatest extent.Be illustrated in figure 4 as impulsive force that spring bears and the relation curve of deflection.By curve as can be known, this shock absorber has played good buffer action, gives the momentum that chaufeur was brought with this impulsive force that reduces to produce in the traffic accident.Simultaneously, because dashpot 10 length are limited to 80mm, when being retracted to a certain degree, can not continue again steering shaft to shrink the normal position of bearing circle when guaranteeing the chaufeur normal driving with this.This device is applicable to the lorry that safety measure is less, because it is simple in structure, does not need circuit control, and effect obviously has considerable practicality.
