Description

A kind of reinforced motor vehicle bumper

Technical field

The utility model belongs to automobile equipment technical field, is related to a kind of reinforced motor vehicle bumper.

Background technology

At present, vehicle has become the indispensable vehicles in people's daily life, thus the security performance of vehicle Increasingly paid close attention to by designer and user.Substantial amounts of safety protection structure is provided with overall vehicle, wherein positioned at vapour The bumper at Chinese herbaceous peony end is to absorb to relax foreign impacts power, protects the safety device of body forward structure；Simultaneously as automobile sets The improvement of meter, it is more and more designed to pedestrian protecting now.

Vehicle in the process of moving, collides and happens occasionally, once occurring, damaged vehicle goes back meeting and ruins people when serious Die.For losing of reducing that vehicle is subject in an impact as far as possible, before designers nearly all concentrate on notice reinforcement vehicle frame The intensity of end position, makes its deformation when being collided in allowed limits.Disadvantage of this is that：Not only greatly increase The complexity and manufacturing cost of its structure, and the rigid collision of vehicle is not broken away from eventually, this is still present very to car and people Big injury possibility.

Bumper before and after current automobile is usually using technique productions such as injection, rotational moulding or blowings, so protecting Several part-structures of dangerous thick stick are mainly plastics composition.Because bumper is made of hard plastic, so without preferable Buffering effect, if bumper collides with other vehicles or building, can bring strongly to the passenger on car Vibrations, seriously can then hurt passenger；And, if the bumper of automobile front and back bumps against pedestrian, the injury to pedestrian Also can be very big, so existing bumper will not bring buffering well to pedestrian.

For example, Chinese patent literature once disclosed a kind of bumper, China Patent No.：ZL200410047102.5； Authorization Notice No.：CN1796185A, it is by thick stick body, baffle plate antihunting device, base antihunting device and two ends connection automotive frame Crossbeam assembly parts are constituted；Its outer layer of thick stick body is elastic steel shoe, and inner side is base, therebetween filled with blob of viscose；Baffle plate antihunting device It is composition, the antihunting device in two lateral symmetry blob of viscose circular holes in thick stick body of completely identical in structure antihunting device It is made up of spring, barrier slides axle and plate washer axle sleeve, spring is set with outside plate washer axle sleeve, both ends of the spring couples baffle plate and bottom respectively Seat, "T"-shaped barrier slides axle is arranged on inside plate washer axle sleeve, and its one end is flushed with baffle plate, and the other end passes through plate washer axle sleeve simultaneously Fastened by nut；Base antihunting device is fixedly mounted on crossbeam assembly parts, and it includes two parts, and a part is chosen by spring Steel, base and crossbeam assembly parts composition, the spring of arc choose the back fixation of steel portion in the base, and spring chooses the pulley at steel two ends It is to be in rolling contact with crossbeam assembly parts；Another part is to choose steel both sides in spring, is respectively provided between crossbeam assembly parts and base There is a completely identical in structure rubber cushion, the rubber cushion is provided with two circular holes, one is respectively installed with circular hole with horizontal vertical Completely identical in structure antihunting device, the antihunting device is made up of spring, base sliding axle and datum axle set, base axle sleeve overcoat Equipped with spring, both ends of the spring couples base and crossbeam assembly parts respectively, and base sliding axle is arranged on inside base axle sleeve, its one end Couple with base, the other end is fastened through base axle sleeve and by nut.

Therefore, a kind of bumper bar that can be brought and preferably buffer how is made, as the problem for needing most solution at present.

Utility model content

Purpose：For weak point of the prior art, the utility model provides a kind of reinforced motor vehicle bumper.

Technical scheme：The utility model provides reinforced motor vehicle bumper, including connecting portion 1, spring 5, bumper 6, Characterized by further comprising the buffer board 2 being connected with connecting portion 1, buffer board 2 is connected by spring 5 with shell 4, shell 4 with protect Dangerous thick stick 6 is connected；The inwall of the shell 4 is provided with buffering clamp 3.

Described buffer board, its thickness is 30~40mm.Described cushion pad is using special vibration-absorptive material.Described Special vibration-absorptive material is obtained by the following method：By natural rubber, butadiene rubber, vulcanizing agent, accelerator, age resistor, dispersion Agent, black stock, polyurethane, modifying agent add banbury, are kneaded, and are given resol resin and methylene is added The mixture of body hexamethylenetetramine, after knead and obtaining elastomeric compound, heat refining shaping, vulcanizing treatment obtains vibration-absorptive material.

Described buffering clamp sets 2~5.

Described buffering clamp is made up of silicon rubber.

Described spring is helical spring.

Beneficial effect：The utility model by structure design, can impact that effectively buffering automobile is received, additionally, institute The buffer board stated is made of special material, with good anti-pressure ability and elasticity, can effectively alleviate driver and crew Sense of discomfort after being impacted.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model

Specific embodiment：

The utility model is further illustrated below in conjunction with the accompanying drawings

In Fig. 1,1- connecting portions；2- buffer boards；3- buffering clamps；4- shells；5- springs；6- bumpers.

The utility model provides reinforced motor vehicle bumper, including connecting portion 1, spring 5, bumper 6, it is characterised in that Also include the buffer board 2 being connected with connecting portion 1, buffer board 2 is connected by spring 5 with shell 4, and shell 4 is connected with bumper 6； The inwall of the shell 4 is provided with buffering clamp 3.

Described buffer board, its thickness is 30~40mm.Described cushion pad is using special vibration-absorptive material.Described Special vibration-absorptive material is obtained by the following method：By natural rubber, butadiene rubber, vulcanizing agent, accelerator, age resistor, dispersion Agent, black stock, polyurethane, modifying agent add banbury, are kneaded, and are given resol resin and methylene is added The mixture of body hexamethylenetetramine, after knead and obtaining elastomeric compound, heat refining shaping, vulcanizing treatment obtains vibration-absorptive material.

Described buffering clamp sets 2~5.

Described buffering clamp is made up of silicon rubber.

Described spring is helical spring.

When reinforced motor vehicle bumper provided by the utility model is impacted, bumper drives bulb compression spring, During extruding, stopped by buffering clamp one by one, progressively cut down impulsive force, finally when spring is extruded to it is final when, Buffer board plays cushioning effect.Cushion pad is made of special material, with good anti-pressure ability and elasticity, can be effective Alleviation driver and crew impacted after sense of discomfort.
