Description

Technical Field

[0001] The utility model belongs to the technical field of automobile shock absorption systems, in particular to an anti-collision shock absorption structure of an automobile chassis. Background Art

[0002] When a car is driving on a dangerous road beside a mountain, the road surface is prone to gravel from mountain landslides. The gravel varies in size. Gravel that is too large can easily damage the car chassis. An anti-collision and shock-absorbing structure is needed to protect the car bottom plate. The existing anti-collision and shock-absorbing structure usually uses a damper for buffering and shock absorption, which has a certain buffering and shock-absorbing effect. However, the sliding and scraping of gravel against the bottom plate will cause damage to the chassis, affecting the protective effect of the anti-collision and shock-absorbing structure on the car chassis.

[0003] Example (authorization announcement number CN213744682U) A shock absorption system for a car chassis relates to the technical field of shock absorption systems, specifically a shock absorption system for a car chassis, comprising a chassis, a spring fixedly installed at the bottom of the chassis, a support frame fixedly installed at one end of the spring, a support seat fixedly installed at one side of the support frame, a fixed plate rotatably connected to one side of the support seat, and a first fixed seat fixedly installed at the bottom of the fixed plate. The shock absorbing system of the automobile chassis has the effect of secondary shock absorption on the vehicle through the setting of the spring. Through the coordinated setting of the chassis, spring and support frame, the vibration generated by the support frame can be transmitted to the spring during use, and the vibration generated by the support frame can be offset by the deformation of the spring, thereby making the chassis shock absorption effect better, thereby playing a role of wide application range and simple structure, achieving the purpose of reducing production costs and reducing the dead weight of the vehicle. The shock absorbing system offsets the vibration during the deformation process of the spring by setting the spring to achieve the protection effect of the chassis, but the shock absorbing system does not take into account the sliding and scraping of gravel and the chassis, which can easily cause damage to the chassis and affect its protection effect on the chassis.

[0025] In order to solve the problem that the chassis and gravel are easily rubbed against each other when the anti-collision and shock-absorbing structure of the automobile chassis is protecting the chassis, resulting in chassis damage and affecting the protective effect of the anti-collision and shock-absorbing structure on the chassis. Figures 1 to 4 The anti-collision and shock-absorbing structure of an automobile chassis shown in the figure includes a chassis body 1, four equidistantly arranged fixing rods 9 are fixedly connected to the bottom of the chassis body 1, the fixing rods 9 are fixed in position, the bottom ends of the fixing rods 9 are fixedly connected to movable blocks 7, the sides of the movable blocks 7 are slidably connected to support plates 2, and the movable blocks 7 are provided to prevent the fixing rods 9 from falling off, thereby improving the structural stability of the components of the anti-collision and shock-absorbing structure, a damper 8 is installed at the top of the support plate 2 through an inner cavity, and the movable end of the damper 8 is fixedly connected to the movable block 7, and the damper 8 is provided to play a role of buffering and shock absorption, thereby realizing the convenient movement of the support plate 2 and improving the flexibility of using the components of the anti-collision and shock-absorbing structure.

[0026] The side of the support plate 2 is rotatably connected to a rotating rod 3 through an opened through groove, and the rotating position of the rotating rod 3 is fixed by setting the support plate 2. The adjacent sides of the two rotating rods 3 are fixedly connected to rollers 4, and both side surfaces of the rollers 4 are rotatably connected to the support plate 2 to fix the rotating position of the rollers 4. The two rollers 4 are rollingly connected to the sides with protective belts 5. By setting the protective belts 5, the chassis of the automobile is protected. The protective belts 5 are used to roll and rub against the gravel at the bottom of the chassis of the automobile to prevent the gravel from directly scraping against the chassis of the automobile, causing damage to the chassis of the automobile, thereby improving the protection effect of the chassis of the automobile. A number of protective plates 6 are fixedly connected to the outer wall of the protective belt 5. By setting a number of protective plates 6, the phenomenon of scraping and sliding friction between the gravel and the protective belt 5 is prevented, which causes the protective belt 5 to be scratched and damaged by the gravel, so that the protective plate 6 scrapes the gravel and follows the rolling friction of the protective belt 5 to achieve the protection of the chassis of the automobile.

[0027] The side of the chassis body 1 is slidably connected with a cylindrical movable plate 13 through an inner cavity for storing active metals such as magnesium or aluminum. By setting active metals such as magnesium or aluminum, under the principle of sacrificial anode protection method, the active metal replaces the automobile chassis for oxidation reaction, prevents the automobile chassis from rusting, and plays a protective role on the automobile chassis. In addition, a single active metal is used to prevent mutual reaction and affect the anti-oxidation effect. The side of the movable plate 13 is fixedly connected with a connecting rod 11. The active metal is located at one end of the movable plate 13 close to the connecting rod 11, which is convenient for taking out through the movable plate 13 The active metal is completely oxidized, and the active metal can be easily removed and replaced. The end of the connecting rod 11 away from the movable plate 13 is fixedly connected with a cylindrical limit plate 10. The side of the limit plate 10 is slidably connected to the chassis body 1. The limit plate 10 is provided to play a blocking role to prevent the outside air from directly contacting the active metal, which causes the active metal to be oxidized by the external environment and affects the protective effect of the active metal on the automobile chassis. At the same time, the connecting rod 11 is provided to realize the synchronous movement and rotation of the movable plate 13 and the limit plate 10. The top and bottom ends of the limit plate 10 are slidably connected with a moving block 15 through the opened inner cavity.

A spring is installed at one end of the moving block 15 away from the moving rod 16, and one end of the spring away from the moving block 15 is fixedly connected to the limit plate 10. The end of the moving rod 16 away from the moving block 15 is fixedly connected with a rubber block 17. The rubber block 17 is provided to prevent the limit plate 10 from moving, thereby improving the anti-skid effect. At the same time, under the action of the spring elastic force, the static friction between the rubber block 17 and the chassis of the automobile is further strengthened to prevent the limit plate 10 from falling off, thereby improving the structural stability of the anti-collision and shock-absorbing structural parts. The rubber block 17 is away from the moving rod 1 One end of 6 is in contact with the chassis body 1, and the top and bottom ends of the connecting rod 11 are fixedly connected with scrapers 12. The scraper 12 is provided to stir the active metal to prevent the active metal from being oxidized in contact with the part of the automobile chassis, which affects the anti-oxidation effect of the automobile chassis. The active metal is stirred by the scraper 12 so that the unoxidized part of the active metal contacts the automobile chassis, thereby improving the protection effect of the automobile chassis. The two end surfaces of the scraper 12 are respectively fixedly connected to the movable plate 13 and the limit plate 10. The side of the limit plate 10 is fixedly connected with a U-shaped pulling block 14. By providing the pulling block 14, it is easy to pull out the limit plate 10, and then take out the completely oxidized active metal through the movable plate 13.

[0029] The damper 8 is a prior art, and its working principle, size and model are irrelevant to the function of the present application, so no further description is given. The control method of the present invention is controlled by a controller, and the control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0030] How it works

[0031] When the user uses the anti-collision and shock-absorbing structure of the automobile chassis, when the automobile chassis contacts and collides with gravel, the gravel directly contacts the protective belt 5, and the protective belt 5 rolls and rubs against the gravel to prevent the gravel from scratching the automobile chassis and causing damage to the automobile chassis. At the same time, a number of protective plates 6 are arranged to prevent the gravel from sliding and rubbing against the protective belt 5, which may cause the protective belt 5 to scratch and damage the gravel, thereby facilitating the protection of the automobile chassis. The roller 4 drives the rotating rod 3 and the support plate 2 to rotate relative to each other, so that the support plate 2 moves longitudinally, so that the movable block 7 and the support plate 2 generate pressure on the damper 8, and the damper 8 plays a role of buffering and shock absorption. The movable block 7 is arranged to prevent the fixed rod 9 from falling off, thereby improving the structural stability of the parts of the anti-collision and shock-absorbing structure.

[0032] The invention prevents the chassis of an automobile from rusting due to long-term use, thereby affecting the firmness of the chassis of the automobile. An active metal is placed in the inner cavity opened on the side of the chassis body 1. The active metal is oxidized instead of the chassis of the automobile through the principle of sacrificial anode protection method, thereby preventing the chassis of the automobile from oxidizing and rusting. The active metal is prevented from being oxidized in the part in contact with the chassis body 1, thereby preventing the active metal from being in loose contact with the chassis body 1. The scraper 12 is rotated to stir the active metal, thereby increasing the contact area between the unoxidized part of the active metal and the chassis body 1, thereby improving the protective effect. When the active metal needs to be replaced, the pull block 14 is pulled, and then the active metal is scraped off through the movable plate 13. After the replacement is completed, under the action of the spring elastic force, the moving rod 16 pushes the rubber block 17 to be in close contact with the chassis body 1 during the transmission process, thereby preventing the moving rod 16 from falling off, thereby causing the active metal to be oxidized by the outside air, thereby reducing the anti-oxidation effect on the chassis of the automobile. The moving block 15 is provided to prevent the moving rod 16 from falling off.
