Description
Technical Field
[0001] The utility model relates to the technical field of automobile bumpers, in particular to a shock absorbing structure of an automobile bumper. Background Art
[0002] Bumpers are installed at the front and rear ends of the car. They not only have decorative functions, but more importantly, they are safety devices that absorb and mitigate external impacts, protect the car body and protect the safety of the passengers.
[0003] Existing automobile bumper shock-absorbing structures mostly use shock-absorbing damping rods to damp the bumper. However, the shock-absorbing damping rods in the existing bumper shock-absorbing structures directly bear the impact force from the front. The shock-absorbing damping rods are easily damaged and cannot be used again, which reduces the service life of the shock-absorbing damping rods. The shock-absorbing damping rods need to be replaced later, which increases maintenance costs. Utility Model Content
[0004] The utility model aims to provide a shock-absorbing structure for automobile bumpers, which has the characteristics of avoiding damage to a shock-absorbing damping rod, repeatedly using the shock-absorbing damping rod and reducing maintenance costs.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a shock-absorbing structure of a car bumper, comprising a mounting box, a moving block is slidably connected inside the mounting box, two cavities distributed on the left and right are provided inside the moving block, two through holes communicating with the cavities are penetrated through the upper end surface of the moving block, a connecting plate matching the through holes is movably connected inside the cavity, and the other ends of the two connecting plates extend to the outside of the through holes and are fixedly connected to the bumper shell together;
[0006] The upper end surface of the moving block is penetrated by two notches distributed on the left and right, the lower end surface of the bumper shell and an inner wall of the two notches are movably connected with a first shock-absorbing damping rod through a hinge seat, and the inner lower end of the installation box and an inner wall of the two notches are movably connected with a second shock-absorbing damping rod through a hinge seat.
[0007] In order to enhance the strength of the bumper shell, as a preferred automobile bumper shock-absorbing structure of the utility model, the interior of the bumper shell is configured as a hollow structure, and a plurality of evenly distributed reinforcing plates are fixedly connected to the interior of the bumper shell.
[0008] In order to prevent the connection plate from directly colliding with the inner lower end of the cavity, as a preferred automobile bumper shock-absorbing structure of the utility model, a spring is fixedly connected between the connection plate and the cavity.
[0009] In order to ensure the smooth movement of the moving block, as a preferred automobile bumper shock-absorbing structure of the utility model, the left and right inner walls of the mounting box are provided with slide grooves, and the left and right side walls of the moving block are fixedly connected with sliders matching the slide grooves.
[0010] In order to limit the position of the connecting plate, as a preferred automobile bumper shock-absorbing structure of the utility model, one end of the connecting plate is fixedly connected to a stopper located inside the cavity and matching the cavity.
[0011] In order to facilitate installation and fixation of the installation box, as a preferred embodiment of the automobile bumper shock-absorbing structure of the utility model, the left and right side walls of the installation box are fixedly connected with installation plates.
[0012] In order to further enhance the strength of the bumper shell, as a preferred embodiment of the automobile bumper shock-absorbing structure of the utility model, a plurality of reinforcing plates form a tripod structure.
[0013] In order to allow the first shock-absorbing damping rod and the second shock-absorbing damping rod to enter the notch, as a preferred automobile bumper shock-absorbing structure of the utility model, the horizontal spacing between the hinge seats movably connected at both ends of the first shock-absorbing damping rod and the second shock-absorbing damping rod is smaller than the length of the notch.
[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0015] The bumper shell cooperates with the moving block to extrude the first shock-absorbing damping rod, causing the first shock-absorbing damping rod to shrink, thereby buffering and shock-absorbing the bumper shell. The moving block cooperates with the mounting box to extrude the second shock-absorbing damping rod, causing the second shock-absorbing damping rod to shrink, thereby buffering and shock-absorbing the moving block. At the same time, the first shock-absorbing damping rod and the second shock-absorbing damping rod rotate. Since the horizontal spacing between the hinge seats movably connected at both ends of the first shock-absorbing damping rod and the second shock-absorbing damping rod is smaller than the length of the notch, the first shock-absorbing damping rod and the second shock-absorbing damping rod can enter the notch, thereby preventing the first shock-absorbing damping rod and the second shock-absorbing damping rod from bearing impact force on the front side, thereby preventing the first shock-absorbing damping rod and the second shock-absorbing damping rod from being damaged.
