Abstract
The utility model relates to a bumper for an energy conversion vehicle, belonging to the technical field of motor vehicle accessories. The bumper for the energy conversion vehicle comprises a bumper and an oil cylinder, wherein a piston of the oil cylinder is arranged at the mid-front part of cylinder cavities; both the cylinder cavities at both sides of the piston are filled with hydraulic oil, and a communicated passage is arranged between the cylinder cavities at both sides; a front positioning spring and a rear positioning spring are respectively arranged between two cylinder bodies at both sides of the piston. The bumper for the energy conversion vehicle has extremely strong strain capacity, can keep the vehicle safe only if the vehicle collides within design technological parameters, has low price, can solve great problems, has no aggression and can be respectively mounted at the front and the back of the vehicle to have good safety effect; and two collided vehicles with the bumpers can be both kept safe no matter the vehicles collide face to face or back to head. The utility model has the advantages of simple structure, easy implementation and reliable performance.
Description
Technical field
The utility model relates to a kind of Conversion of energy formula automotive bumper, belongs to power car attachment technique field.
Background technology
At present, employed bumper/spoiler can reduce following a few class substantially on the automobile: the one, and very stiff and demanding formula bumper/spoiler, it is made of metallic material, and install simultaneously the front end or the rear and front end that are installed in automobile during use.The advantage of this bumper/spoiler is simple in structure, and its weak point is relatively poor to the protective value of vehicle; The 2nd, utilize the bumper/spoiler of springing, this bumper/spoiler can play buffer action when collision happens, thereby reaches the purpose of protection vehicle.Its protective value is better, and weak point is the collision situation that this class bumper/spoiler is difficult to adapt to various complexity, and safe reliability is poor; The 3rd, a kind ofly be tending towards intelligentized safety device, collision can be avoided or slow down to this device, but its cost of manufacture height.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of Conversion of energy formula automotive bumper of simple in structure, dependable performance.
The utility model adopts following technical scheme:
The utility model comprises bumper/spoiler and oil cylinder, it is characterized in that the piston of said oil cylinder is in the middle front part in cylinder chamber, the cylinder chamber of piston both sides all is full of hydraulic oil, and is provided with communication passage between cylinder chamber, both sides, is respectively equipped with prelocalization spring and back retainer spring between piston both sides and cylinder body.
Be provided with Connection Block between the piston rod front end of the said oil cylinder of the utility model and bumper/spoiler, Connection Block and bumper clamp are connected for sphere between Connection Block and piston rod front end.
The said oil cylinder of the utility model is the oil cylinder that 2～5 spaced and parallel are arranged.
The said communication passage of the utility model is to be located at the intercommunicating pore on the piston or to be located at intercommunicating pore on the piston rod.
When using this bumper/spoiler, the cylinder body and the car body of oil cylinder installed and fixed.The principle of work of this bumper/spoiler is such; When bumping, bumper/spoiler is stressed, and promote piston rod, piston successively, make piston oppress the interior hydraulic oil of its rear side cylinder chamber body, hydraulic oil just flows in the cylinder body cavity of piston front side along communication passage, and hydraulic oil changes into heat energy with the application force that damages or antagonistic force and dissipates in flow process.
Good effect of the present utility model is as follows: the utility model adaptability to changes extra-heavy, as long as vehicle is sent out the back collision in its designing technique parameter, can ensure safety basically, and use this utility model to spend seldom can solve big problem.The utility model is not with any aggressiveness, can all load onto front and back on same car, and its guarantee is effective.If the car of two collisions all is equipped with this bumper/spoiler, promptly be not afraid of head-on crash, not to be afraid of behind yet and to knock into the back, two cars are harmless safely in pairs.The utility model simple structure, easy to implement, dependable performance.
Description of drawings
Fig. 1 cuts open structural representation for the master office of looking of a kind of embodiment of the utility model.
In the accompanying drawings: 1 bumper/spoiler, 2 Connection Blocks, 3 piston rods, 4 prelocalization springs, 5 intercommunicating pores, 6 pistons, 7 intercommunicating pores, 8 back retainer springes, 9 cylinder bodies, 10 oil cylinders.
The specific embodiment
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:
Referring to accompanying drawing, comprise bumper/spoiler 1 and oil cylinder 10 in the formation of Conversion of energy formula automotive bumper provided by the utility model.Bumper/spoiler 1 can adopt multiple shape to make, and as pipe, square tube or channel-section steel etc., helps reducing cost of manufacture like this.The piston 6 of oil cylinder 10 is in the middle front part in cylinder chamber, and is located by prelocalization spring 4 and back retainer spring 8 that piston 6 both sides and 9 of cylinder bodies are established respectively.Piston 6 is in front end 1/4 place, cylinder chamber and manages whole position.Be full of hydraulic oil in the whole cylinder chamber of cylinder body 9, and be provided with communication passage between the two parts that the cylinder chamber are separated into by piston 6.Communication passage can be to be located at the intercommunicating pore 7 on the piston 6 or to be located at intercommunicating pore 5 on the piston rod 3, also can be to be located on piston 6 outer rims or the longitudinal groove on cylinder body 9 inwalls, can also on cylinder body 9 two ends sidewalls, offer intercommunicating pore, and connect by being located at cylinder body 9 exterior high pressure fuel pipes.Hydraulic oil in the cylinder chamber also medium such as available water or pressurized air substitutes.
According to bumper/spoiler with joining vehicle different, the configuration of the oil cylinder 10 of this energy conversion type automotive bumper can be selected between 2-5, answers parallel interval to arrange between oil cylinder.When being used for Oversize vehicle, when this bumper/spoiler adopted more cylinder to count, oil cylinder can adopt two-layer arrangement up and down.Piston rod 3 front ends and 1 of the bumper/spoiler of oil cylinder 10 are provided with Connection Block 2, and Connection Block 2 can be made of two halfbodies.Connection Block 2 and bumper/spoiler 1 available screw, nut are connected and fixed, and 3 in Connection Block 2 and piston rod adopt sphere to be connected, and help adapting to the collision situation of various complexity like this.
Be located at the intercommunicating pore 7 on the piston 6 and be located at the number of the intercommunicating pore 5 on the piston rod 3 and the size in aperture with joining vehicle relevant, all can determine by test.
