Abstract
The utility model relates to a vehicle collision protection device used for protecting a driver and passengers in a vehicle when the vehicle (especially a bus) collides. The existing vehicle collision bumper is usually formed by processing glass fiber or a metallic component with thin walls, collision energy is only absorbed by the self deformation of the integral component, and the absorbed energy is limited. When a severe collision happens, the existing vehicle collision bumper can not efficiently reduce the deformation of a car carriage to protect drivers and passengers. The utility model provides a combined vehicle collision protection device which comprises a collision touch component to form a cushion chamber with a vehicle body, wherein a flexible buffering element which can be positioned by a positioning element is arranged in the cushion chamber. A damping elastic element is arranged between the flexible buffering element and the vehicle body in a collision stress direction. The utility model can efficiently absorb and reduce the collision energy, can reduce the deformation of the vehicle body and protect drivers and passengers when the vehicle collides.
Description
[technical field]
The utility model relates to a kind of automobile hit impact protection device, is used for protecting when bumping at automobile (especially motorcoach) safety of chaufeur, passenger in the car.
[background technology]
At present, automobile is in order to reduce the deformation degree of car body when bumping with other vehicles or obstacle, avoids the injury to driver and crew in the car that causes thus as far as possible, and its front end generally is provided with crashproof parts (being bumper/spoiler), to absorb crash energy.
Existing bumper/spoiler adopts glass fibre or metal thin-wall spare to process usually; only depend on the deformation of this integral member itself to absorb crash energy; the energy that absorbs is very limited; when violent collision takes place (as car to car impact takes place on express highway), can not reduce automobile bodies deformation effectively and protect driver and crew's safety.
[utility model content]
Basic task of the present utility model and main purpose are to overcome above shortcomings in the prior art; a kind of combined type automobile hit impact protection device is provided,, effectively absorbs crash energy to reach when automobile bumps; reduce car body deformation degree, effectively protect driver and crew's purpose of safety.
For this reason; the utility model adopts following technical scheme: combined type automobile hit impact protection device; it is characterized in that: it comprises and cooperates the colliding force triggering piece that forms a cushion chamber with car body; be provided with the flexible buffering piece with the locations location of can breaking in the cushion chamber, this flexible buffering piece is subjected to be provided with on the force direction and between the car body damped elasticity spare in collision.When automobile and other vehicle or obstacle bump, colliding force triggering piece is at first collided and is out of shape, inwardly compress cushion chamber and absorb certain crash energy, when deformation acquires a certain degree, colliding force triggering piece touches flexible buffering piece and makes its distortion, and flexible buffering piece can significantly absorb energy.The impulsive contact force that is subjected to when flexible buffering piece reaches maxim and is enough to cut off in the time of can breaking locations, and the locations that can break disconnects, and this disconnection process can absorb certain crash energy again.After the locations that can break disconnected, the flexible buffering piece edge was moved by force direction and is made damped elasticity spare generation deformation, and damped elasticity spare also can absorb crash energy in deformation process.Thus, when automobile bumped, a plurality of parts of hit impact protection device can repeatedly absorb crash energy, thereby amplitude peak ground alleviates the influence to car body, protection driver and crew's safety.
As to the improving and replenishing of technique scheme, the utility model adopts following technical measures:
This device comprises that also one is fixed on the bracing frame on the car body, and described flexible buffering piece is fixed on one and slides on the support, and described bracing frame is respectively equipped with slide rail and the slide rail beam that matches with sliding on the support, be connected with a pin between described slide rail and the slide rail beam.Pin is easy to install and change as the locations that can break, and when pin is cut off, flexible buffering piece is stressed when rearward mobile, and set slide rail and slide rail girder construction can play good directional tagging to it, is convenient to and the cooperating of damped elasticity spare.
Described damped elasticity spare comprises one group of damping energy-absorbing spring, and an end of this group spring links to each other with flexible buffering piece, and the other end is connected on the spring dead plate of being located on the car body.Set up a plurality of damping energy-absorbing springs can play energy-absorbing function better, further the protective effect of stiffening device.
The beneficial effects of the utility model are: adopt a plurality of parts repeatedly to absorb the reduction crash energy when automobile bumps, reduce car body deformation, protection driver and crew's personal safety.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to view.
Fig. 3 is slide rail of the present utility model, slide rail beam and pin part structural representation.
[specific embodiment]
Combined type automobile hit impact protection device as shown in Figure 1, 2; bumper/spoiler 1 (colliding force triggering piece) surrounds a cushion chamber 10 with car body 6; one vertical spring dead plate 5 is installed on the car body 6 of a side in the chamber; spring dead plate 5 links to each other with an end of damping energy-absorbing spring assembly 4; the other end of damping energy-absorbing spring assembly 4 then is connected with and slides support 3, slides and is installed with spare tyre 2 (flexible buffering piece) on the support 3.
When automobile bumps, deformation takes place earlier in bumper/spoiler 1, inwardly compress cushion chamber and absorb certain crash energy, when deformation acquires a certain degree, bumper/spoiler 1 touches spare tyre 2 and makes its distortion and significantly absorb energy, the impulsive contact force that is subjected to when spare tyre 2 reaches maxim and when being enough to cut off pin 9, pin 9 disconnects, and this disconnection process can absorb certain crash energy again.Then, spare tyre 2, slide support 3 and slide rail beam 8 and move backward and compression damping energy-absorbing spring assembly 4 along slide rail 7 together, also can absorb crash energy in this process.
Present embodiment only is a kind of preferable technical scheme, specifically can make appropriate change according to description.
