Specific embodiment
It is described in detail below in conjunction with specific embodiment of the attached drawing to the disclosure.It should be understood that this place is retouched
The specific embodiment stated is only used for describing and explaining the disclosure, is not limited to the disclosure.
As shown in Figures 1 to 5, the disclosure provides a kind of Energy Absorbing Structure, including fixes bracket 1 and be installed to this and fix
Energy absorption device on bracket 1, energy absorption device include energy-absorbing plunger 2 and shell 3, which includes 31 He of inner wall being oppositely arranged
Outer wall 32, and the side wall 33 being connected between inner wall 31 and outer wall 32, side wall 33, inner wall 31 and outer wall 32 surround liquid jointly
One end of pressure chamber, energy-absorbing plunger 2 is telescopically connected to inside hydraulic pressure chamber, and hydraulic pressure chamber is separated into two chambers, the other end
The outside of hydraulic pressure chamber is arranged in protrusion, is provided on energy-absorbing plunger 2 and enables to hydraulic indoor oil liquid 4 between two chambers
The buffer structure 5 of circulation.
It is filled with oil liquid 4 in its middle hydraulic chamber, and the pressure balance between two chambers is guaranteed by buffer structure 5.When
Energy absorption device by extraneous impact force when, energy-absorbing plunger 2 is moved towards the direction for the chamber for being located inside, at this point, being located at interior
The indoor oil liquid of side chamber can be passed to the chamber in outside by buffer structure, and specifically, buffer structure can be multiple damping holes
Or pressure limiting valve consumes collision energy in this way, converting kinetic energy into thermal energy when oil liquid circulates between two chambers, thus
It can play the role of buffering energy-absorbing.After the unloading of the external force suffered by the energy-absorbing plunger 2, energy-absorbing plunger 2 can be towards the chamber in outside
Direction movement, again keep two chambers between balance.It should be noted that " inside, outside " mentioned above is needle
What the position on vehicle defined is installed to for Energy Absorbing Structure, is inside close to vehicle interior, the side far from vehicle
Outside.
Further, in the present embodiment, as shown in Figures 2 and 3, one end of energy-absorbing plunger 2 also passes through elastic element 6

Existing elastic shock attenuation.Specifically, elastic element 6 is compressed spring, or may be elastic block rubber, is not limited this disclosure
System.When energy absorption device is by external force, energy-absorbing plunger 2 can be moved first, realize that oil liquid flows between two chambers, same with this
When, the elastic element 6 of energy-absorbing plunger 2 is also compressed, and the elastic compression deformation of elastic element 6 can also consume part kinetic energy,
The energy-absorbing damping in collision process is furthermore achieved.On the other hand, when by slight collision external force, elastic element 6
Elastic-restoring force facilitates the reset of energy-absorbing plunger 2.
Specifically, as shown in Fig. 2, in the present embodiment, energy-absorbing plunger 2 includes telescopically being plugged into inside hydraulic pressure chamber
Bar portion 21 and the head 22 that is arranged in outside hydraulic pressure chamber, bar portion 21 include connecting rod 211 and hydraulic pressure chamber be separated into two chambers
The partition 212 of room, partition 212 are arranged in parallel with head 22 and are connect by connecting rod 211, wherein buffering is provided on partition 212
Structure 5.It in other words, can be by pushing connecting rod 21 further to push partition 212 towards interior when head 22 is collided external force
The chamber movement of side, oil liquid 4 will be flowed between two chambers by the buffer structure 5 on partition 212, kinetic energy converted
For thermal energy, collision energy is consumed.
In addition, in the present embodiment, head 22 is formed as limit stops plate, and the cross-sectional area of the limit stops plate is not
Less than the cross-sectional area of outer wall 32.On the one hand, head 22 is equivalent to cover board, and mating connection bar 211 realizes the complete envelope of hydraulic pressure chamber
It closes, and when by external force, plays the role of limit stops, avoid the buffer invalidation of energy absorption device；On the other hand, head 22
Area is greater than the area of outer wall 32, namely makes head 22 when receiving extraneous collision and moving towards outer wall 32, can with it is outer
The solution touching completely of wall 32, namely the contact area of the two is maximized, the collision for outer wall 32 is reduced, the work of damping is further functioned as
With.
Wherein, in the present embodiment, the jack 7 being cooperatively connected with connecting rod 21 is offered on outer wall 32.In this way, can
It enough realizes the installation of the bar portion of energy-absorbing plunger 2, and can be realized the external setting on head 22, and connecting rod 21 and jack 7
It is cooperatively connected, in conjunction with the setting on head 22, realizes being fully sealed for hydraulic pressure chamber.
Specifically, as shown in figures 1 and 3, in the present embodiment, fixed bracket 1 includes connecting bracket 11 and limit branch
Frame 12, connecting bracket 11 include two the first mounting portions of connection main body 111 with the both ends for being connected to the connection main body 111
112, two second installations of the limiting bracket 12 including anterior spacing main body 121 and the both ends for being connected to the anterior spacing main body 121
Portion 122, correspondingly, two the first mounting portion 112 one-to-one correspondence are welded on two the second mounting portions 122,121 shape of anterior spacing main body
As n shape, connects main body 111 and be formed as the U-shaped positioned opposite with anterior spacing main body 12, the roof 8 of anterior spacing main body 121 forms limited
Position hole 81, energy absorption device pass through limit hole 81 and are welded to the bottom wall 9 of connection main body 111, and roof 8 and 9 relative spacing of bottom wall are set
It sets.
That is, connecting bracket 11 is responsible for for energy absorption device being fixed on car body component by the first mounting portion 112, and
The fixation with limiting bracket 12 is realized by the first mounting portion 112.And then responsible mating connection bracket 11 will be whole for limiting bracket 12
A energy absorption device carries out limit arrangement, is specifically restricted to anterior spacing main body 121 by shell 3 and connects the interval between main body 111 set
In the space set, guarantee the fixed installation of energy absorption device, it is avoided to generate shaking.Certainly, in other embodiments, connection branch
Frame and limiting bracket can also be any other suitable structure, as long as can satisfy fixed and limit energy absorption device.
According to another aspect of the present disclosure, a kind of vehicle is also provided, including Energy Absorbing Structure disclosed above, Ke Yigen
This Energy Absorbing Structure is applied to vehicle body everywhere according to the force status of vehicle, slows down impact force, guarantee occupant safety and
Riding comfort.
Specifically, as shown in figure 5, in the present embodiment, vehicle includes B-pillar assembly 10, which includes side wall
Outside plate 101 and B column inner panel 103, and the B column reinforcement plate 102 being arranged between the side-wall outer-plate 101 and B column inner panel 103, Gu
Fixed rack 1 is welded between B column reinforcement plate 102 and B column inner panel 103.
In this way, side-wall outer-plate 101, B column reinforcement plate 102 power that is collided are subjected to displacement when side collision occurs for vehicle,
With the increase of impact force, part deforms, as shown in figure 4, this Energy Absorbing Structure occurs when part strain is close to Pe
Effect, by replace it is traditional absorb collision energy by metal plastic deformation, increase B-pillar assembly to reach and absorb collision energy
