Automobile collision buffering and energy-absorbing device

Abstract

The invention relates to the technical field of automobile protection accessory devices, in particular to an automobile collision buffering and energy-absorbing device which can limit a buffering column after a first spring is compressed to a certain compression amount so as to prevent the first spring from driving a front bumper to rebound. The device comprises a fixed seat, a buffer column, a first spring, a first mounting plate and a second mounting plate, and a buffer groove is formed in the center of the left side wall of the fixed seat; the device further comprises a second upper spring,a second lower spring, an upper clamping plate, a lower clamping plate, an upper pull rope, a lower pull rope, an upper pull ring and a lower pull ring, an upper clamping groove and a lower clampinggroove are formed in the right half areas of the top end and the bottom end of the buffer column correspondingly, and an upper sliding groove and a lower sliding groove are formed in the right half areas of the inner top side wall and the inner bottom side wall of the buffer groove correspondingly. An upper through hole and a lower through hole are longitudinally formed in the right half areas ofthe top end and the bottom end of the fixed seat correspondingly.

Description

technical field [0001] The invention relates to the technical field of automobile protective attachments, in particular to an automobile collision buffer energy-absorbing device. Background technique [0002] As everyone knows, the automobile collision buffer energy-absorbing device is an auxiliary device used to buffer and protect the front bumper of the automobile when it is hit by the outside world, and it has been widely used in the field of automobile protection; the existing The automobile collision buffer energy-absorbing device includes a fixed seat, a buffer column, a first spring, a first mounting plate and a second mounting plate. The outer wall of the column and the inner wall of the buffer tank can be in sliding close contact, the left end of the first spring is connected with the central area of ​​the right wall of the buffer column, the right end of the first spring is connected with the central area of ​​the right wall of the buffer tank, and the left end of ...

[0002] As everyone knows, the automobile collision buffer energy-absorbing device is an auxiliary device used to buffer and protect the front bumper of the automobile when it is hit by the outside world, and it has been widely used in the field of automobile protection; the existing The automobile collision buffer energy-absorbing device includes a fixed seat, a buffer column, a first spring, a first mounting plate and a second mounting plate. The outer wall of the column and the inner wall of the buffer tank can be in sliding close contact, the left end of the first spring is connected with the central area of ​​the right wall of the buffer column, the right end of the first spring is connected with the central area of ​​the right wall of the buffer tank, and the left end of the buffer column is connected with the first The central area of ​​the right side wall of the mounting plate is connected, and the right end of the fixing seat is connected with the central area of ​​the left side wall of the second mounting plate; when the existing automobile collision buffer energy-absorbing device is used, the longitudinal sections of the buffer column and the buffer groove are square, so that the buffer column It is more stable when sliding in the buffer groove, the first mounting plate is connected with the front bumper of the car, and the second mounting plate is connected with the front of the car body; it is found in the use of the existing car collision buffer energy-absorbing device that the front bumper is damaged When impacting, the buffer column quickly compresses the first spring. After being compressed to the end, due to the elastic force of the first spring, the front bumper will pop out, which will accidentally injure the surrounding personnel, resulting in poor reliability
