Abstract

The utility model relates to a counterweight dummy for an automobile crash test, comprising a head, a neck, an upper trunk, a lower truck, upper limbs and lower limbs. The externals of the head, the neck, the upper trunk, the lower truck, the upper limbs and the lower limbs are covered by skins made of neoprene materials and the internals are supported by a skeleton. The beneficial effect of the counterweight dummy for the automobile crash test is that all parts of the skeleton of the counterweight dummy are connected with each other by artificial joints, so that the counterweight dummy is as flexible as a crash test dummy and can simulate motion poses of a human body in the crash test. An assembly structure is adopted for the skeleton of the counterweight dummy and the skeleton is assembled by bolts, which is beneficial for disassembling and assembling. In a test without requiring data acquisition, the counterweight dumpy can replace the test dummy for the crash test, thereby reducing damages on the test dummy and cost. By pasting a sheet type sensor on the skeleton, related data acquisition is performed.

Description

Counterweight dummy in vehicle impact testing

Technical field

The utility model relates to the counterweight dummy in a kind of vehicle impact testing.

Background technology

More and more universal along with automobile, people also more and more pay attention to automotive safety, and most automobile all is equipped with air bag now, needs the service test dummy to carry out a large amount of impact tests in coupling air bag process.

The impact test process that service test dummy is mated air bag is such: press standard-required and place the testing dummy on test vehicle, use the multi-form impact walls of draw-off equipment towing vehicle collision according to the speed of standard-required again, acquisition configuration is in the data of the various kinds of sensors at testing dummy each position, analyze the size of colliding the injury values that human body is caused, adjust the air bag parameter, reach the optimization of injury values with it.Existing testing dummy, it is to be made of head, neck, upper trunk, lower trunk, upper limbs, lower limb, in the impact test process, the testing dummy is because the impact of collision has damage.The housing that testing dummy's head inside is formed by the alloy aluminum monoblock cast and the outside skin that coats consist of, and the backbone of upper metastomium adopts Plate Welding to make, can only integral replacing after damage; Lower trunk is made of monoblock cast alloy aluminum and the outer wrap skin of inside; Upper limbs only can be dismantled at joint owing to not needing to carry out data acquisition, and remainder adopts skin directly to be coated on skeleton and makes, can only integral replacing in case damage; Present testing dummy does not have a Related product due to domestic, can only import, and after testing dummy's parts damages, replacement cost is all very high, and the cycle is also long.

For addressing the above problem, be the kerb weight requirement consistent with the kerb weight of the design of vehicle of satisfying test vehicle in impact test, when not needing image data, can the service test dummy or with substitutes such as the suitable sandbag of testing dummy's weight or steel plates, carry out the associated crash test.Can produce following result like this: the first, service test dummy carries out impact test, can cause unnecessary damage to the testing dummy, causes the increase of experimentation cost; The second, use the substitutes such as sandbag or steel plate to carry out impact test, can't simulate the athletic posture of human body in process of the test; The 3rd, the substitutes such as sandbag or steel plate, its center of gravity and testing dummy make a big difference, and can produce certain impact to test figure.

Summary of the invention

The problem that the utility model solves has been to provide the counterweight dummy in a kind of vehicle impact testing, be intended to the problem that the solving collision test can't be simulated the human motion attitude to testing dummy's unnecessary damage and substitute, reduce experimentation cost, satisfy the requirement of local collision test.

In order to solve the above problems, the utility model is realized by following scheme:

Counterweight dummy in a kind of vehicle impact testing, comprise head, neck, upper trunk, lower trunk, upper limbs, lower limb, its special character is: head, neck, upper trunk, lower trunk, upper limbs, the inner skeleton that uses of lower limb each several part support, the each several part skeleton interconnects by joint prosthesis, and skeleton is demountable structure, and the outside skin of neoprene material that adopts of each several part covers.

The head inner skeleton is spliced to form by a plurality of osteocommas, and splicing position use bolt and retainer nut or screw are fixed, the outside skin that coats the neoprene material of skeleton;

Spine portion in upper trunk is spliced into hollow structure by four block plates, and is screwed;

The lower trunk skeleton adopts up and down two block plates and four aluminium sheets splicings on every side, fixes by the screw that passes aluminium sheet, and external skin is sleeved on skeleton and is screwed;

Skin of upper extremity is sleeved on the upper limbs skeleton and is screwed;

Head, on paste SMD sensor on trunk, lower trunk skeleton, can carry out the collection of related data when needing.

Compared with prior art, the beneficial effects of the utility model are:

1, skeleton adopts joint prosthesis to interconnect, have identical degree of freedom with the testing dummy, can simulate the athletic posture of human body in impact test, alternate test dummy in the impact test that does not need image data, to reduce impact test to testing dummy's damage, reduce experimentation cost;

2, adopt splicing structure, screw fastening is easy to install, dismantle, and is convenient to change after parts damages, can reduce experimentation cost, is applicable to all kinds of counterweight dummies such as 95 hundredths, 50 hundredths, 5 hundredths, child dummy.

Embodiment

The below is take 5 hundredths Female dummies as example, with specific embodiment, the utility model is further described by reference to the accompanying drawings, but the utility model is not limited to the embodiment content, is equally applicable to all kinds of counterweight dummies such as 95 hundredths, 50 hundredths, 5 hundredths, child dummy.

As shown in Figure 1, counterweight dummy is by head (1), neck (2), upper trunk (3), lower trunk (4), upper limbs (5), lower limb (6), the outside skin of neoprene material that adopts covers, and the inner skeleton that uses of each several part supports, and connects by joint prosthesis (7) between each skeleton;

As shown in Figure 2, dummy's head inner skeleton (101) is spliced to form by a plurality of osteocommas (101a), the splicing position uses double-screw bolt (101b) and retainer nut (101c) or screw to fix, the outside skin (102) that coats the neoprene material of skeleton, be pasted with SMD sensor (8) on head inner skeleton (101), this structure is convenient to change after damage;
