Abstract
The utility model discloses a car collision buffer comprises bumper, leaf spring, cushion rubber piece, buffer spring, hydraulic pressure post, connecting rod. The bumper is directly connected with a steel plate spring, a buffer rubber block is connected behind the steel plate spring, and 3-6 buffer springs are arranged in the buffer rubber block. Forming a first-level buffer; the left end and the right end of a first connecting rod connected with the steel plate spring are provided with first buffer springs and are connected with the hydraulic column through a second connecting rod. Two telescopic columns are symmetrically arranged on the left and the right of the bumper and are connected and fixed by a mounting plate to form secondary buffering. And a second buffer spring is arranged between the first connecting rod and the mounting plate to form three-level buffer. The automobile buffer device can buffer for three times when an automobile is seriously collided, thereby improving the collision capacity of the automobile, reducing the collision speed and simultaneously improving the safety guarantee for personnel in the automobile.
Description
Technical Field
The utility model provides a car collision buffer belongs to car protection device technical field.
Background
Automobiles have long become a very relevant vehicle in people's lives because of their convenience and rapidness. In recent years, along with the improvement of the living standard of people, the possession of automobiles is continuously improved. However, motor vehicle traffic accidents also show an increasing trend year by year. With the continuous development of the automobile industry, the automobile driving speed is faster and faster, when the automobile collides frontally, the part which is collided firstly is the bumper, and the traditional bumper cannot meet the requirement of automobile safety during high-speed collision. When the vehicle is in collision at a high speed, the head of the vehicle is seriously deformed by the huge inertia force. Therefore, there is a need for a shock-absorbing device capable of reducing acceleration at the time of collision and enhancing a shock-absorbing ability at the time of collision of an automobile, which can protect persons in the automobile while protecting the appearance of the automobile as much as possible.
Disclosure of Invention
To the problem that the prior art is not enough, the utility model aims to provide a car collision buffering
The device can enhance the collision energy absorption capacity, reduce the acceleration of the automobile during collision, and protect the safety of people in the automobile and the appearance of the automobile.
To achieve the above object, the present invention provides an automobile collision buffer device. Automobile collision buffer
The device comprises a bumper, a steel plate spring, a buffer rubber block, a connecting rod, a hydraulic column and a telescopic rod.
The automobile collision buffer device comprises a buffer spring, hydraulic pressure and a telescopic rod. The buffering energy-absorbing device mainly has three: the first buffer springs are arranged at two ends of the first connecting rod, the hydraulic column is connected to the first connecting rod through springs, and the second buffer springs are arranged between the first connecting rod and the mounting plate.
The automobile collision buffer device has buffering rubber block installed in the back of the steel plate spring
3-6 buffer springs are arranged in the block.
A connecting rod is connected with a buffer rubber block and a hydraulic column.
The utility model discloses a car collision buffer's effective income is: the energy absorption device is arranged behind the automobile bumper, the buffer rubber block is arranged behind the steel plate spring, and the buffer rubber block and the hydraulic column are connected through the connecting rod, so that the energy absorption capacity of the automobile in collision is improved, the acceleration of the automobile in collision can be reduced, and the safety of personnel in the automobile can be better protected.
Drawings
Fig. 1 is a general structural view of a collision buffer apparatus for an automobile.
In the drawings: 1-bumper 2-steel plate spring 3-buffer rubber block 4-telescopic column 5-first connecting rod 6-first buffer spring 7-second connecting rod 8-hydraulic column 9-second buffer spring 10-pulley 11-mounting plate.
Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in figure 1, the utility model discloses car crash cushion includes bumper 1, and leaf spring 2 is being connected to bumper 1, and leaf spring 2 is connected with cushion rubber piece 3. And a second buffer spring 9 is arranged at two ends of a connecting rod connected with the buffer rubber block 3, and is connected with a hydraulic column 8 by a pulley 10 of a connecting rod II 7. Two telescopic columns 4 are symmetrically arranged on the left and the right of the bumper 1 and are connected and fixed by a mounting plate 11. And a second buffer spring 9 is arranged between the first connecting rod 5 and the mounting plate 11.
When the car bumper received the striking, the impact force passes through bumper 1, transmit leaf spring 2, leaf spring 2 is used for the cushion rubber piece 3 to the effect of effort, the effect of buffering has been played, cushion rubber piece 3 received power is continued the effect and the first buffer spring 6 at connecting rod 5 both ends, the connecting rod drives first buffer spring 6 to both ends compression under the effect of effort, meanwhile, flexible post 4 and the downward motion of second buffer spring 9 also simultaneously, play the cushioning effect. The first buffer spring 6 is connected with the hydraulic column through the pulley, and the second connecting rod 7 moves downwards under the action of force to play a role in buffering again. Therefore, when the automobile is impacted, the safety of the automobile engine and the driver and passengers can be effectively protected.
