detailed description

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

The utility model is an extended energy storage device for the front bumper of a car, as shown in Figure 1, comprising an energy storage cylinder 4 symmetrically arranged at the front end of the vehicle frame 1, and a spring 2 is fixedly connected to the inside of the energy storage cylinder 4, and the spring 2 is connected to the front end of the vehicle frame. One end face of the plunger 7 is connected, and the end face connected between the plunger 7 and the spring 2 is sleeved in the energy storage cylinder 4, and the middle part of the front end of the vehicle frame 1 is provided with a connecting plate 3, and the connecting plate 3 is connected to one end of the support rod 6 through a movable pin , two support rods 6 are arranged symmetrically, one end surface of the plunger 7 away from the spring 2 is fixedly connected to the bumper 8, and the middle part of the bumper 8 is connected to the other end of the support rod 6 symmetrically. Buffer 5 is welded on the bumper 8 . As shown in FIG. 2 , a support seat 11 is provided on the side of the vehicle frame 1 away from the energy storage cylinder 4 , and a guide member 10 is provided on one side of the energy storage cylinder 4 , and the support seat 11 and the guide member 10 are located on one side of the vehicle frame 1 , the guide piece 10 is welded on the front end of the vehicle frame 1, the inside of the guide piece 10 is sleeved with an extension sub-rod 9, one end of the extension sub-rod 9 is connected to the support seat 11, and the other end of the extension sub-rod 9 is welded on the bumper 8.
