CN2167897Y - Buffer safety-bar for motor vehicle - Google Patents

Abstract

The utility model discloses a buffer safety-bar for motor vehicles which is composed of a front buffer plate, a middle buffer plate, and a back buffer plate. A telescopic guide rail which is arranged between the front buffer plate and the back buffer plate is connected with a tension spring which passes through the middle buffer plate. Compression springs are arranged between the back buffer plate and the middle buffer plate, and between the middle buffer plate and the front buffer plate. The back buffer plate which is fixed on a vehicle frame by a screw bolt and a mounting frame extends out towards the front of the automobile. When two vehicles or objects collide, the front buffer plate first makes contact with and presses the spring, the middle buffer plate moves towards the back to counteract or reduce the partial impact force by the counterforce of the compression spring. Therefore, the goal of accidental loss of the collision of the vehicles can be reduced and decreased. So, the utility model is the ideal buffer safety-bar for motor vehicles.

Description

Buffer safety-bar for motor vehicle

The utility model relates to a kind of power actuated vehicle buffer safety device, is a kind of automobile buffer safety bumper.

At present, Federal bumper, mostly be to make with channel-section steel, narrow do not have elasticity, when car accident takes place when, usually cause the serious accident of car crash, disclosing application number on the Chinese utility model patent communique is 90206997.7 " automobile buffer safety devices ", and its structure is to connect between front buffer plate and back dash plate or be set with spring, the bumper/spoiler of back dash plate and self-propelled vehicle front end is connected and fixed, this device has certain effect, but because only to have used compression spring, spring to lack cushion effect little, spring has been grown the front buffer plate vibration, when hitting on one side, spring is power by bending, and buffering effect is bad.

The purpose of this utility model provides a kind of multilayer automobile buffer safety bumper, can not alleviate impulse force to solve existing bumper/spoiler, and the inapplicable problem of automobile buffer safety device reaches the purpose that reduces or reduce the car accident loss.

The purpose of this utility model is achieved in that (former bumper clamp place) vertical fixing one erecting frame on self-propelled vehicle front end vehicle frame, on erecting frame by bolt one back dash plate, dash plate and front buffer plate in dash plate front, back is provided with, preceding, be provided with telescopic guideway between the back dash plate, be fixedly connected with extension spring, extension spring passes middle dash plate, after, in, be provided with compression spring between preceding, bumper/spoiler forwards leans out, and when two cars or the collision of car thing, front buffer plate is contact earlier, and compression spring, make spring produce bounce,, reach the purpose that reduces or reduce the car accident loss to offset and to reduce the part impact.

This utility model compared with prior art has the following advantages: (1) multilayer dash plate, and the low rigidity of spring height is big; (2) be provided with telescopic guideway between the dash plate before and after, bumper/spoiler thickness is big, is subjected to force direction good, and cushion effect is big; (3) width is big, dolly can not take place when big or small car to car impact yet creep into phenomenon under the cart.

Be described further below in conjunction with accompanying drawing:

Fig. 1, automobile buffer safety bumper structural representation;

Fig. 2, A-A cut-away view;

Among Fig. 1-2: the dash plate (1) of back, middle dash plate (3), front buffer plate (5) all adopts steel plate to make, dash plate has at least 4 bolts hole on (1), corresponding with erecting frame (10), be evenly equipped with 1-2 row extension spring (6) above, every row has 4-8, be evenly equipped with the 1-3 row pressure spring (2) that contracts, every row has 6-15, at line of centers intrinsic scalability guide rail (7) or be with the telescopic sleeve pipe guide rail up and down in the extension spring outside, guide rail is dove-tail or tubular, on extra heavy pipe (7-3), be provided with guide groove, in be sliding combined with tubule (7-1), there is banking pin (7-2) the one end, in like manner can withered one-tenth 3-4 section, middle dash plate (3) has the 1-2 piece, intrinsic guide pin (12) on its line of centers top and bottom, can in guide-track groove, slide and swing extension spring (6) and compression spring (2), (4) be fixed on dash plate (1) by bolt (8), (3), (5) on.

Claims (4)

1, a kind of automobile buffer safety bumper is by front and back dash plate (1), (5), spring (2) and bolt (3) are formed, it is characterized in that: in front and back dash plate (1), (5) be provided with middle dash plate (3) between, telescopic guideway (7) is arranged, having 1-2 row's extension spring (6) to pass middle dash plate (3) is fixed on the dash plate of front and back, in dash plate (1) and (3), (3) and be provided with compression spring (2) between (5), (4), dash plate (3) can reciprocatingly slide along telescopic guideway (7), and this bumper/spoiler is by bolt (9), erecting frame (10) is fixed on the vehicle frame (11).

2, baffle safety bumper/spoiler according to claim 1 is characterized in that: there is 1-3 row compression spring (2), (4), and every row has 6-15.

3, baffle safety bumper/spoiler according to claim 1, it is characterized in that: telescopic guideway (7) is to be dove-tail or tubular, on extra heavy pipe (7-3), guide groove is arranged, in be sliding combined with tubule (7-1), there is banking pin (7-2) the one end.

4, baffle safety bumper/spoiler according to claim 1 is characterized in that: dash plate (3) has the 1-2 piece, intrinsic guide pin (12) on its line of centers top and bottom.
