The fixing device comprises a cylindrical fixing block arranged on a bed surface, a connecting column for installing the dummy thigh is arranged on the upper end face of the fixing block, and a fixing base for being connected with the bed surface is arranged on the lower end face of the fixing block. The dummy thigh can be fixed firmly and prevented from shaking under impact due to the fixing device.
Description
Technical field
The utility model belongs to automobile safety collision test field, relates to a kind of dummy's thigh stationary installation of dummy's foot Calibrating experimental bench.
Background technology
Vehicle safety performance has also become the problem of driver and occupant's overriding concern, it also is one of most important performance of automobile, strengthening the research of automotive safety, reduce the Road Traffic Injury of China, is that the whole society pays close attention to and make great efforts one of important social concern that solves jointly.Vehicle impact testing is that all automobile R﹠D processes are necessary, but because this test has danger and destructiveness, therefore in the middle of impact test, the dummy who uses the physical characteristics with true man substitutes true man.By head, chest and foot the dummy various sensors are installed, gather the data such as the power of dummies in collision process, displacement, acceleration with these sensors, by these data, just can analyze the injured degree of true man in the traffic accident, and then the security performance of automobile is carried out qualitative assessment.
When head-on crash occurs in automobile in the process of moving, because inertia, human body has a displacement forward, and the limited space that automobile provides for human foot, therefore the car body component of the foot position such as pedal can be to instantaneous opposition of foot, and this acting force can damage human foot.Therefore, vehicle impact testing need to be tested dummy's foot.And before the automobile real vehicle collision test, because last time test or other reasons, the data of dummy's foot inside may misalignment, therefore need to dummy's foot be demarcated by test, and are in good condition to guarantee dummy's foot.The demarcation of dummy's foot is carried out at a foot Calibrating experimental bench, dummy's thigh is fixed on the testing table table top, and dummy's foot is placed in the foot holder, and the foot that clashes into the dummy by a pendulum draws data.Dummy's thigh is direct sheathed being fixed on the fixed block at present, can produce larger impulsive force to dummy's thigh during owing to pendulum bump dummy foot, causes rocking of dummy's thigh, thereby has affected the accuracy of foot rating test.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, a kind of dummy's thigh stationary installation of dummy's foot Calibrating experimental bench has been proposed, dummy's thigh stationary installation of this dummy's foot Calibrating experimental bench can with the fixation of dummy's thigh, occur rocking when avoiding dummy's thigh to be subject to impacting.
The purpose of this utility model can realize by following technical proposal: a kind of dummy's thigh stationary installation of dummy's foot Calibrating experimental bench, comprise that one is arranged on the cylindrical fixed block on the table top, it is characterized in that, the upper surface of described fixed block is provided with for the joint pin that dummy's thigh is installed, and the lower surface of fixed block is provided with for the firm banking that connects table top.
Fixed block can guarantee the height requirement after dummy's thigh is installed, and joint pin can make dummy's thigh firmly be installed on the fixed block, occurs rocking when avoiding dummy's thigh to be subject to impacting.Fixed block is fixed on the table top by firm banking, makes whole stationary installation firmly stable.
Described joint pin radially offers one for the connecting hole that dummy's thigh is installed.Dummy's thigh carries bolt, wears connecting hole by this bolt dummy's thigh is fixed.During the foot rating test, pendulum frontal impact dummy foot, the axial direction of connecting hole is consistent with the crash direction of pendulum, satisfies dummy's thigh from the installation requirements of strap bolt.
Described firm banking is plate-like, and above-mentioned fixed block is connected on the table top by this firm banking.The firm banking of plate-like can make stable being fixed on the table top of fixed block.
Described firm banking is connected on the table top along the circumferential equally distributed bolt of firm banking by several.Be bolted, easy disassembly, simultaneously bolt evenly distributes, and avoids bolt strained inequality, causes indivedual bolt strained excessive and fracture.
Described joint pin is positioned at the middle part of fixed block, and fixed block is positioned at the middle part of firm banking.Location when making things convenient for thigh to install can make whole stationary installation stressed evenly simultaneously.
Described fixed block and joint pin, firm banking are one-body molded.Increase the strength of joint between the three, and one-body molded processing is convenient.
Compared with prior art, dummy's thigh stationary installation of this dummy foot Calibrating experimental bench has the following advantages:
1, owing to be provided with joint pin at fixed block, offers connecting hole on the joint pin, more stablize firmly so dummy's thigh is installed on the fixed block, avoided the phenomenon that occurs rocking when being subject to impacting.
Be connected on the table top by the firm banking bolt during 2, owing to fixed block, so easy accessibility is easy to operate.
3, owing to joint pin, fixed block and the moulding of firm banking three in one, so strength of joint is high, easy to process.
