Background technique
Currently, it is more to the comparison of the collision safety research of vehicle both at home and abroad, in the prior art in relation to car energy absorption device
Installation site is in bus frame front or stringer front mostly, and car passes through the axis of energy absorption device during head-on crash
It is deformed to conquassation and carries out energy-absorbing, reduced car acceleration peak value, reduce the injures and deaths of occupant.When car bumps against the truck of front,
Since the bottom height from the ground of lorry compartment is higher, the collision energy-absorbing device being arranged on prior art microbus is lower than truck
Car bottom causes car collision energy-absorbing device when knocking into the back truck to be inserted into the bottom of boxcar, causes in collision process
Middle collision energy-absorbing device effect is smaller；When car bumps against the car of front, after being higher than car due to the height of bus frame
Standby case height, car can ride up on car when collision, cause the collision energy-absorbing device effect in collision process smaller.
202827752 U of patent CN discloses car central collision collapse energy-absorption structure, which includes along vehicle frame left and right directions
The frame cross of extension, bumper, two pieces of mounting plates for being fixed on frame cross front end face, the cant beam for increasing mounting plate intensity,
Upper layer and lower layer energy-absorbing cylinder is equipped between bumper and each mounting plate, ensure that should when higher or lower object is hit
Endergonic structure can be sufficiently crushed, and protect the safety of occupant well.But on a mounting board due to the installation of energy-absorbing cylinder,
And mounting plate is directly anchored on the front end face of vehicle frame, plays support fixation to mounting plate by the front end face of vehicle frame, in this way
Mounting plate is necessarily dependent upon vehicle frame and can just be fixed, therefore the mounting height range of mounting plate may be restricted to the height of vehicle frame,
To limit the highly protective range of the energy absorption device, and if improving its altitude range, and meeting by increasing mounting plate
Because the intensity deficiency of mounting plate causes security risk.
Summary of the invention
It is an object of the present invention to provide the highly protective range that can improve collision energy-absorbing device and reinforce its mounting structure

Stating energy-absorbing tube stent further includes cant beam in vertical beam rear, extending from bottom to top from back to front, and the cant beam has and institute
The lower end stating the connected upper end of vertical beam and being connected with vehicle frame.
The energy-absorbing tube stent further includes having the web beam for being fixedly arranged on the vertical beam upper end.
Collision energy-absorbing device, including mounting plate and energy-absorbing cylinder, the collision energy-absorbing device further includes energy-absorbing tube stent, described
Energy-absorbing tube stent includes for being arranged at intervals on vehicle frame front end up/down face, up and down direction side by side along frame cross length direction
The vertical beam of extension, vertical beam have for vehicle frame be connected lower end, the energy-absorbing tube stent further include in vertical beam rear, from
The cant beam extended from bottom to top before backward, the lower end that the cant beam has the upper end being connected with vertical beam and is connected with vehicle frame.
The energy-absorbing tube stent further includes having the web beam for being fixedly arranged on the vertical beam upper end.
The mounting plate is fixedly arranged on the front end face of the energy-absorbing tube stent.
The energy-absorbing cylinder is fixedly arranged on the mounting plate, the mounting plate be equipped with energy-absorbing cylinder section be adapted
Mounting hole.
The section of the energy-absorbing cylinder is in sphere of movements for the elephants shape, is internally provided with " ten " font stiffening plate.
The seamed edge of the energy-absorbing cylinder along its length is equipped with conquassation induction hole.
Vehicle, including frame cross, the vehicle further include collision energy-absorbing device described above.
Present invention employs the energy-absorbing tube stents that can be set to vehicle frame up/down face, since the bracket includes along frame cross
Length direction is arranged at intervals on the vertical beam in vehicle frame front end up/down face side by side and increases the cant beam of the support intensity, the cant beam
Both ends correspondence be fixed on vertical beam and vehicle frame, between the vertical beam and cant beam and vehicle frame formed a triangular structure, make this
Bracket intensity with higher, the energy-absorbing tube stent front end face is provided with collision energy-absorbing device, by bracket instead of existing skill
Fixation supporting role of the front end face of vehicle frame to collision energy-absorbing device in art, makes the highly protective range of the collision energy-absorbing device not
It is confined to the height of vehicle frame, and force structure is reasonable, support strength is high.
