Description
Technical field
The utility model is related to bus man safety guards, and car head-on crash mistake is avoided more particularly, to one kind
The extruded retractile high intensity cockpit of driver's living space in journey.
Background technology
Car is located at vehicle body forefront due to the congenital deficiency of body structure in slightly serious head-on crash accident
Driver's cabin be easy to deform in collision process, the living space of driver is occupied, and driver is difficult to get rid of poverty after leading to accident
With rescued, or even can be squeezed by interior component and by grievous injury.Existing safety belt and air bag can not be this
In the case of enough protections are provided for driver, it is therefore desirable to a kind of device ensures the living space of driver in collision process
In do not deform easily.
Utility model content
The purpose of the utility model is to overcome the deficiencies of existing safeguard measure, and it is empty to provide a kind of existence ensureing driver
Between the device occupied is not extruded during head-on crash, it is simple in structure, change cost it is less.
The utility model is achieved through the following technical solutions：
A kind of car energy-absorbing is shunk back formula driver's living space protection structure, including is fixed on the vehicle frame of car front floor
High intensity cockpit pedestal, the driver's seat seat that is fixed on the high intensity cockpit pedestal, the high intensity drives
The front end of bilge seat is provided with the guardrail higher than driver's shank, and the guardrail is provided with the first energy-absorbing dress at car headstock
It sets, the second energy absorption device is provided between the rear end and car front floor vehicle frame of the high intensity cockpit pedestal.
Further, 8 centimetres of the knee position height the or more when height of the guardrail is taken higher than driver.
Further, front side, left side, the right side of the high intensity cockpit pedestal are welded on car front floor vehicle frame
On.
Further, throttle, brake pedal are connected directly between on the high intensity cockpit pedestal.
Compared with prior art, the utility model has the following advantages that and advantageous effect：
Body frame structure for automotive itself is without making excessive change, it is only necessary to the fraction structure of driver workspace is replaced, without additional
Electronic control unit, cost is relatively low, and reliability is high, the possibility of errorless triggering.When normal vehicle operation, the environment of driver's compartment
It is no different with before structural behaviour and installation, is adapted to without driver.When collision occurs, it can guarantee that cockpit space is not squeezed
The living space of compressive strain, driver is protected, and it is injured general in head-on crash accident to greatly reduce bus man
Rate greatly improves passive safety of the driver in head-on crash.The deformed region of vehicle frame headstock is limited in driving
Member and passenger injure in minimum region, and the energy in collision process is made in a planned way to be inhaled by the energy absorption device on vehicle frame
It receives, both ensure that the living space of driver was not occupied, and in turn ensured the safety of passenger.

Specific implementation mode
To more fully understand the utility model, the utility model work is further retouched with reference to the accompanying drawings and examples
It states, but the embodiment of the utility model is unlimited so.
Embodiment
As shown in Figure 1 to Figure 3, a kind of car energy-absorbing shrink back formula driver's living space protection structure, for can avoid visitor
Vehicle driver's living space in head-on crash accident is squeezed, including the high intensity being fixed on car front floor vehicle frame 1
Cockpit pedestal 2, the driver's seat seat 6 being fixed on the high intensity cockpit pedestal 2, the high intensity cockpit pedestal
2 front side, left side, right side are welded on car front floor vehicle frame 1, the front end setting of the high intensity cockpit pedestal 2
There is the guardrail 3 higher than driver's shank, to give driver leg enough safety, the height of the guardrail 3 should be higher than that driving
8 centimetres of knee position height or more when member takes, the guardrail 3 is provided with the first energy absorption device 4 at car headstock, described
High intensity cockpit pedestal 2 rear end and car front floor vehicle frame 1 between be connected with the second energy absorption device 5.
When normal vehicle operation, high intensity cockpit pedestal 2 and car front floor vehicle frame 1 collectively form complete vehicle
Floor vehicle frame is divided on head, the integral strength and stability of monocoque body when common guarantee car is run.Due to cockpit and visitor
Active force between vehicle carriage is much smaller than the active force for making connecting portion that yield deformation occur, can between cockpit and bus frame
It is considered as rigid connection, high intensity cockpit pedestal becomes a part for bus frame, at this time the case where cockpit and way-train
Cockpit in situation be no different.
When passenger car hair gives birth to more serious head-on crash, car front floor vehicle frame 1 deforms, preceding object
Object will touch the first energy absorption device 4 of the guardrail 3 and car vehicle head part in 2 front of high intensity cockpit pedestal, the first energy-absorbing dress
Setting 4 crumples deformation ensures the crash acceleration of high intensity cockpit 2 in the maximum magnitude that human body can be born.Energy absorption device 4 will
Collide stress to cage cockpit 2 conduct, to push cage cockpit 2 to tailstock direction move, be mounted on base rear portion with
5 stress crumple deformation of the second energy absorption device between bus frame simultaneously absorbs the energy that collision generates.Due to high intensity cockpit 2
Intensity be higher than car front floor vehicle frame 1 intensity, the two junction nearby will deform, to ensure high intensity drive
The structure in cabin is intact, is not deformed with the deformation of car front floor vehicle frame 1, and then ensures that the necessary existence of driver is empty
Between do not occupied in collision process.
As can be seen that when more serious head-on crash occurs for car, the vehicle head part of bus frame deforms, high
First energy absorption device 4 of the guardrail 3 in 2 front of intensity cockpit pedestal can ensure that the acceleration of driver's seat seat 6 exists by energy-absorbing first
In the maximum magnitude that human body can be born, to reduce the chance of injury of driver.High intensity cockpit pedestal 2 and second is inhaled simultaneously
Can device 5 all can be by compared with noticeable effort, since the intensity of second energy absorption device 5 at 2 rear portion of high intensity cockpit pedestal is less than
The intensity of cockpit, the second energy absorption device 5 can deform prior to the frame distortion of cockpit and aft passenger region, cockpit
Part is shunk back backward together together with driver's seat seat 6, brake pedal 7, ensures that the living space of driver and driver rear multiply
The integrality of objective living space.
As shown in Figure 4,5, driver's seat seat 6, throttle, brake pedal 7 are directly connected to high intensity cockpit pedestal 2.
The bonding strength of driver's seat seat 6 and high intensity cockpit pedestal 2 can guarantee when a collision occurs, the driver's seat seat 6 with
It has been that the driver of safety belt moves and driver's seat seat 6 is not driven with high intensity together with high intensity cockpit pedestal 2 on seat
Bilge seat 2 is sailed to be detached from.The bonding strength of throttle, brake pedal 7 and high intensity cockpit pedestal 2, which can guarantee, works as collision
Shi Buyu pedestals are detached from and lead to driver's leg injury.
It should be noted that the above is only the preferred embodiment of the utility model only, not limiting this practicality
It is novel, within the spirit and principle of the utility model, made by all any modification, equivalent and improvement etc., should all include
It is within the protection scope of the present utility model.
