Description

{Structure for improving hood strike in automobill}

The present invention relates to a hood striker improvement structure for an automobile, and more particularly, when a pedestrian hits a hood latch of a car to satisfy a pedestrian law, a striker, which is a steel structure, acts as a rigid body to prevent adverse effects on pedestrians. The invention relates to a hood striker improvement structure for automobiles.

In general, a hood is provided to cover the engine compartment of the vehicle, and the hood is selectively opened and closed for the maintenance of the engine compartment including the engine, the transmission, and various parts necessary for driving the vehicle. It must be fixed so that opening and closing of the car is not possible.

To this end, as shown in FIG. 1, a general vehicle is provided with a striker 20 at an inner front side of the hood 10 in a state of being positioned on an upper surface of an engine room, and is fastened with the striker 20 to fix the hood 10. Latch (not shown) is installed on the frame of the vehicle so that can be fixed.

However, such a striker has the following problems as shown in FIG.

Each automaker is considering pedestrian performance from the design stage to cope with increasingly pedestrian regulations and merchandise. As described above, when the pedestrian-oriented safety aspect is considered, as shown in FIG. 2, the striker 20 fastened to the hood 10 when the pedestrian collides with the vehicle hood 10 pushes diagonally and collides with the hood latch and the frame. do. Due to this, the striker 20, which is a simple steel structure, acts as a rigid body, causing adverse effects on pedestrian protection.

That is, during impact impact, the hood striker is not deformed into a rigid body of the steel casting, but after contact with the frame and the hood latch, the impact value of the pedestrian is further increased.

The present invention has been proposed to solve the above problems, as the striker fixed to support the hood when the pedestrian hits the front of the car can absorb the impact without acting as a rigid body to reduce the injury of the pedestrian. The purpose is to provide an automotive hood striker improvement structure that can be.

The hood striker improvement structure for an automobile according to the present invention for achieving the above object is fixed to the hood in combination with a hood provided to cover the engine room of the vehicle, and a latch provided in the front inner side of the hood and installed in the frame. A striker provided to be able to be provided, comprising: a pair of support parts provided at the front inner side of the hood and fixed at an end thereof, a fixing part provided at the other end of the support part so as to slide up and down, and inside the fixing part; It is configured to include an elastic spring installed to support the lower end of the support, respectively.

According to the improved structure of the hood striker for automobiles according to the present invention, the improvement of the pedestrian protection performance is pursued by each manufacturer, but it is not easy to improve the performance due to the limited layout and design constraints. It is possible to maximize the pedestrian protection effect in the space, to secure a collision energy absorption space as a relatively simple structure, as well as to improve the merchandise by improving the pedestrian performance.

Hereinafter, the configuration of the hood striker improvement structure for an automobile according to the present invention and its embodiments will be described in more detail with reference to the accompanying drawings.

3 is a view showing the configuration of the hood striker improved structure for an automobile according to the present invention, Figure 4 is a view showing the operating state of the hood striker improved structure for an automobile according to the present invention, Figure 5 is in accordance with the present invention This is a perspective view of the hood striker retrofit structure for automobiles.

A hood provided to cover and protect an engine room of a vehicle, and a striker configured to be fixed to the hood in combination with a latch provided on the front inner side of the hood so as to fix the hood, the front inner side of the hood 10 A pair of supports 100 are provided, the ends of which are fixed to the hood 10 panel or bracket.

The other end of the support part 100 is fitted to the upper / lower sliding and the fixing part 200 is provided to be fastened and fixed to the latch (not shown) provided on the frame of the vehicle.

An elastic spring 210 is installed in the fixing part 200 to support the lower end surface of the support part 100 so that the support part 100 can be pushed upward at all times.

In addition, the support part 100 is composed of an orifice tube of the aperture mechanism installed in the fluid flow path, the compression fluid 220 is introduced into the fixing part 200 can absorb the shock by buffering action.

In addition, the speed of opening and closing the general hood 10 is within 10KPH, but at least 35KPH at the time of pedestrian collision, so the hood 10 to match the weight of the hood 10 for each vehicle type according to the size of the orifice tube of the support part 100. It is adjustable so that it closes to the hood latch when closing. This is because the collision speed of the car and the pedestrian is larger than the closing speed of the hood 10 so that the support 100 is not compressed into the fixing part 200 when the hood 10 is closed.

Hereinafter, a method of operating the hood striker improvement structure for automobiles according to the present invention will be described.

When the pedestrian collides with the hood 10 of the front part of the vehicle, the impact energy starts to rise when the bottom surface of the fixing part 200 contacts the front frame or the hood latch of the vehicle by the impact.

As such, when the impact energy rises and the bottom surface of the fixing part 200 stops after contacting the front frame or the hood latch, the support part 100 fitted to be slidable up / down inside the fixing part 200 is high due to the impact energy. While compressing the elastic spring 210 into the inside of the government 200, the compressive fluid 220 moves into the support 100 while reducing the speed of the support 100 through the orifice tube of the support 100. Compression can mitigate the impact.
