Embodiment 1

[0024] Embodiment one, see figure 2 , a front safety device for automobiles, comprising a front frame 1 of the cabin, a buffer connection structure 7 and a front bumper assembly 6, the buffer connection structure 7 is connected to the front side of the front frame 1 of the cabin by screws 8, the buffer connection structure 7 It includes a grid-shaped main body 71 and a reinforced protective edge 72, the grid-shaped main body 71 and the reinforced protective edge 72 are integrated, the reinforced protective edge 72 is arranged on the lower side of the grid-shaped main body 71, and the reinforced protective edge 72 is along the Extending in the left and right directions, the front surface of the reinforced protective edge 72 is a raised arc surface that smoothly transitions from left to right, and the grid holes 711 on the grid-shaped main body 71 are quadrilateral holes. The grid-shaped main body 71 and the reinforced protective edge 72 Made of PP material, the front bumper as...

Embodiment 2

[0025] Embodiment two, see image 3, the difference from Embodiment 1 is that the grid holes 711 on the grid-like main body 71 are regular hexagonal holes, so that the grid-like main body 71 is a honeycomb structure, and the grid-like main body 71 and the reinforced protective edge 72 are PE material, there is a gap between the rear surface of the front bumper assembly 6 and the front surface of the buffer connection structure 7, and several cylinders 712 are arranged on the front surface of the grid-like main body 71 of the buffer connection structure 7, and the front bumper The rear side of the lever assembly 6 is provided with a supporting rod 62 matching the cylinder 712. The supporting rod 62 is inserted and sealed in the cylinder 712 in a one-to-one correspondence. Front frame 1 is provided with longitudinal rod 11, the rear end of longitudinal rod 11 is connected on the vehicle frame 9, and the front end of longitudinal rod 11 is connected on the rear side of nacelle fr...

Embodiment 3

[0028] Embodiment three, see Figure 6 , the difference from the second embodiment is that the grid-shaped main body 71 and the reinforced protective edge 72 are made of POM material, and the collapse-guiding structure 10 is two rows of diamond-shaped through holes 104 penetrating the left and right sides of the longitudinal bar 11, Two rows of prismatic through holes are symmetrically distributed on the upper and lower sides of the axis 111 of the longitudinal bar. The rhombus through holes 104 in each row are distributed along the axial direction of the longitudinal bar 11. The distance between each rhombus through hole 104 and the axis 111 of the longitudinal bar is Equal, the rhombus-shaped through-hole positioned at the bottom of the axis of the longitudinal axis is larger than the rhomboid-shaped through-hole positioned at the top of the axis of the longitudinal rod, and the plane 105 defined by the left and right corners of each rhombic hole is parallel to the axis 111 o...

Abstract

The invention relates to an automobile safety protection device, in particular to an automobile front bumper device, which comprises an engine cabin front part framework, a front bumper assembly and a buffer connection structure, wherein the buffer connection structure is connected onto the front side of the engine cabin front part framework through screws, the front bumper assembly is connected onto the front side of the buffer connection structure, the buffer connection structure comprises a lattice type body and a reinforcing protection edge, and the reinforcing protection edge is arranged on the lower side edge of the lattice type body, is in an integral structure with the lattice type body and extends in the left and right directions of an automobile. The invention provides the automobile front bumper device with the advantages that components are few, the connection is convenient, the anti-collision capability is high, and the light weight degree is high. The problems of many components, complicated installation, low light weight degree and weak anti-collision capability of the existing car front bumper device are solved.

Description

technical field [0001] The invention relates to a car safety protection device, in particular to a car front safety device. Background technique [0002] The main part of the front safety device of the car is the front bumper of the car. The front bumper of the car is a safety device used to absorb and ease the impact from the front of the car and protect the front of the car body. The front bumper of the car in the 1980s is made of metal materials. Mainly, the steel plate is stamped into a U-shaped groove structure, and the surface is treated with chrome plating and other methods, and it is riveted or welded with the frame longitudinal beam, but there is a large gap between the bumper and the body of this structure , seems to be an added part, which affects the appearance of the vehicle and is not accepted by users. [0003] In order to realize the harmony and unity of the bumper and the whole vehicle and reduce the weight of the car, the front bumpers of many models of ca...
