Abstract
The utility model discloses a kind of extension type steering column for vehicles, including upper power transmission shaft, lower drive shaft, safety pin, upper sleeve pipe, setting of casing, bearing, support and sliding block, the upper power transmission shaft is with the lower drive shaft by safe pin connection, the upper power transmission shaft is connected with upper sleeve pipe by bearing, the upper sleeve pipe is fixed on the support, and the sliding block is connected as a single entity by four safety pins of injection moulding with support.When there is head-on crash in automobile, upper power transmission shaft will be collapsible into lower drive shaft, steering wheel is moved downwardly together together with upper power transmission shaft, and then force sleeve pipe to be retracted setting of casing, so as to the distance pulled open with drive the human world, ensure that driver there are enough living spaces, crash energy can be absorbed, prevent or mitigate that driver is subject to injures.
Description
Technical field
The utility model relates to automobile technical field, specifically refers to a kind of extension type steering column for vehicles.
Background technology
The collision safety sex chromosome mosaicism of automobile there is since being born from automobile, and in early days because speed is relatively low, vehicle is relatively
Do not cause the attention of people less and, with car large-scale production and use, also due to the continuous improvement of speed, collision safety
Sex chromosome mosaicism is increasingly protruded.
Steering wheel and steering column, with the distance of driver quite it is near, when there is frontal impact, they are often to cause to drive
Head part, the main cause of chest trauma.For controlling the steering wheel and steering column of automobile steering, just turn into the twinkling of an eye in accident
Most fatal weapon.
Chinese utility model patent application（Application number：200820001718.2）Disclose a kind of with the adjustable of energy-absorbing function
Steering column, including turn upward axis, stacked switch support, column jecket, adjusting bracket, steering lower axle, mounting bracket and universal-joint fork.It is logical
Cross and turn injection molding body fracture between upward axis and lower axle, in upper axle indentation lower axle, apparatus with shock absorbing protects driver, but should
Adjustable steering column energy absorbing members are single.
The content of the invention
The purpose of this utility model seeks to provide a kind of extension type steering column for vehicles, and the mechanism is automatic by steering column
Contraction is entered, so as to the distance pulled open with drive the human world, it is ensured that driver has enough living spaces, can absorb collision energy
Amount, prevents or mitigates that driver is subject to injures.
To achieve the above object, the extension type steering column for vehicles designed by the utility model, including upper power transmission shaft, pass down
Moving axis, safety pin, upper sleeve pipe, setting of casing, bearing, support and sliding block, the upper power transmission shaft is with the lower drive shaft by safety
Pin connection, the upper sleeve pipe is fixed on the support, and the upper power transmission shaft is connected with upper sleeve pipe by bearing, and the sliding block passes through
Four safety pins of injection moulding are connected as a single entity with support.
Further, the upper power transmission shaft passes through spline drived with lower drive shaft.
Further, the upper power transmission shaft respectively has two apertures with lower drive shaft in spline-fitting portion, there is note in aperture
It is moulded the safety pin of type.
Further, safety pin is resin pin.
Further, the fit system between the upper sleeve pipe and setting of casing is linear contact lay interference fit.
Compared with prior art, the utility model has advantages below：
Because when automobile occurs head-on crash, steering column can be to after-contraction, it is ensured that driver has enough living spaces.
The main energy absorbing members of this collapsible steering column of bushing type be the connection of upper bracket and sliding block safety pin and it is upper,
Setting of casing, in collision process, converts kinetic energy into heat energy, absorbs crash energy, prevents or mitigate that driver is subject to injures.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is phantom.
Fig. 3 is safety pin detailed structure figure.
Wherein, 1-upper power transmission shaft, 2-lower drive shaft, 3-safety pin, 4-upper sleeve pipe, 5-setting of casing, 6-bearing,
7-support, 8-sliding block.
Specific embodiment
The following is specific embodiment of the utility model and with reference to accompanying drawing, further is made to the technical solution of the utility model
Description.
Extension type steering column for vehicles as shown in Figure 1, including upper power transmission shaft 1, lower drive shaft 2, safety pin 3, upper set
Pipe 4, setting of casing 5 and bearing 6, the upper power transmission shaft 1 are connected with the lower drive shaft 2 by safety pin 3, the upper power transmission shaft 1
It is connected by bearing 6 with upper sleeve pipe 4, the upper sleeve pipe 4 is fixed on the support 7, the sliding block 8 passes through four of injection moulding
Safety pin 3 is connected as a single entity with support 7.
During automobile occurs actual collision, the safety pin of connecting bracket and sliding block is cut first absorbs a part of dynamic
Can, then sliding block departs from from support, and to ensure not receive axial constraint when sleeve pipe and steering spindle are shunk, upper power transmission shaft has downward
Movement tendency, now safety pin be subject to shearing force, when the limit is born more than safety pin, safety pin is cut, upper power transmission shaft to
Lower mobile a part of impact energy of absorption, and concede a part of space, it is ensured that driver has enough living spaces, such direction
Disk is moved downwardly together together with upper power transmission shaft, and then forces sleeve pipe to be retracted setting of casing, and upper and lower sleeve pipe occurs under force
When relative movement, the contact site between them can slide and elastic-plastic deformation occurs so as to inhale because interference fit is extruded
Receive energy.By rubbing twice, heat energy is converted kinetic energy into, absorb crash energy, prevent or mitigate that driver is subject to injures.
Above-described specific implementation, has been carried out further to the purpose of this utility model, technical scheme and beneficial effect
Describe in detail, should be understood that and the foregoing is only specific embodiment of the utility model, be not limited to this reality
With new, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvements done etc. all should be included
Within protection domain of the present utility model.
