Technical Field

[0001] The invention relates to the technical field of automobile parts, in particular to an automobile side guard plate with a buffer structure. Background Art

[0002] Large vehicles such as trucks and vans have high chassis and their fuel tanks are much larger than those of small vehicles. Their fuel tanks are often fixed under the chassis. Therefore, they need to be protected to prevent them from being hit or scratched when driving on the road. People often use car side guards to protect the fuel tanks.

[0003] The fixing frame of the automobile side guard plate is generally installed on the side below the chassis of a truck or large automobile, and then people use fixing pins and locking pins to lock the side guard plate, thereby protecting other parts of the automobile fuel tank. When a large automobile is driving on the road, if there is a scratch or collision, the side guard plate can withstand the impact for the fuel tank and reduce damage to the fuel tank. However, the existing side guard plates are mostly single-plate structures. If there is a collision or scratch in daily life, the side guard plate will be deformed, which will lead to safety hazards such as the side guard plate getting stuck or aging. Therefore, it is necessary to design a car side guard plate with a buffer structure to protect and buffer the fuel tank of a large automobile. Summary of the invention

[0009] Furthermore, it also includes a plurality of limiting members, which are fixed on one side of the buffer frame close to the transmission wheel, and the limiting members are extruded and matched with the chain.

[0010] Furthermore, it also includes a buffer mechanism that can provide buffering when the side guard plate is lowered. The buffer mechanism includes a plurality of second fixing members, which are respectively fixed to a side of the fixing frame close to the side guard plate. The second fixing members are slidably connected to the buffer members, and a plurality of third telescopic springs are fixedly connected between the second fixing members and the buffer members.

DETAILED DESCRIPTION

[0032] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0033] Example 1

[0034] A car side guard with a buffer structure, see Figure 1-Figure 6 , including two fixing frames 11, the front side of the fixing frame 11 is rotatably connected to the side guard plate 1, and the side guard plate 1 is connected to a locking mechanism capable of locking the side guard plate 1, and second telescopic springs 191 are fixed to the upper, lower, left and right corners of the front side of the side guard plate 1, and a buffer frame 14 is fixed to the front end of the second telescopic spring 191, and the buffer frame 14 is composed of two trusses and a plurality of rods fixed between the trusses. The left and right sides of the buffer frame 14 are inclined, and one end of a sliding rod 19 is fixedly connected to the four corners on the rear side of the buffer frame 14, and the other end of the sliding rod 19 passes through the second telescopic spring 191 and is slidably connected to the side guard plate 1, and a sliding component capable of supporting the buffer frame 14 is fixed to the side guard plate 1.

[0035] See also Figure 4-Figure 6 The sliding assembly includes three first fixing members 15, and the first fixing members 15 are fixed to the left and right sides and the middle position of the middle part of the side guard plate 1. The first fixing members 15 are rotatably connected to the first rotating rods 16. The first rotating rods 16 are composed of two left and right rotating rods. The rear parts of the two rotating rods are rotatably connected. The front parts of the two rotating rods are fixed with sliding blocks 17. The sliding blocks 17 are slidably connected to the rods of the buffer frame 14. The two sliding blocks 17 are respectively fixedly connected to the upper and lower trusses of the buffer frame 14 with first telescopic springs 18.

[0036] See also Figure 2-Figure 3 The locking assembly includes two latches 12, which are both clamped between the left and right sides of the rear side of the side guard plate 1 and the fixing frame 11, and nuts 13 are threadedly connected to the latches 12.

[0037] When people need to install the side guard plate 1 on a large automobile, the device can be used to protect the fuel tank and other parts of the automobile. First, people fix the fixing frame 11 to the side under the chassis of the large automobile, and then lock the side guard plate 1 on the fixing frame 11 through the latch 12 and the nut 13. When the large automobile is hit from the side, the front side of the buffer frame 14 is hit first, and the buffer frame 14 moves backward due to the impact. The second telescopic spring 191 is compressed, and the buffer frame 14 drives the sliding rod 19 to move backward. The buffer frame 14 drives the sliding block 17 to move backward. The sliding block 17 squeezes the first rotating rod 16. The left and right rotating rods on the first rotating rod 16 rotate toward the upper and lower sides respectively. Each first rotating rod 16 drives the two sliding blocks 17 on the first rotating rod 16 to move toward the upper and lower sides respectively. The first telescopic spring 191 is compressed, and the sliding block 17 is compressed. The springs 18 are compressed, the first telescopic spring 18 and the second telescopic spring 191 are compressed and play a buffering role, thereby playing a buffering role for the vehicle or person that hits the buffer frame 14, thereby protecting the fuel tank and components of the large vehicle. When the buffer frame 14 is no longer hit, the second telescopic spring 191 resets and drives the buffer frame 14 to move forward and reset, the buffer frame 14 drives the sliding block 17 to move forward and reset, the sliding block 17 drives the two rotating rods on the first rotating rod 16 to move toward the side close to each other, the first telescopic spring 18 resets, and the first telescopic spring 18 drives the sliding block 17 to move toward the side close to each other and reset. The above-mentioned mechanism can play a buffering role for the objects and people that hit when the large vehicle is hit from the side, thereby protecting the fuel tank and components of the large vehicle.

[0038] Example 2

[0039] Based on Example 1, please refer to Figure 7-Figure 9 , and also includes an anti-scratch mechanism that can effectively provide buffering protection when encountering scratches from the side. The anti-scratch mechanism includes twelve second rotating rods 21, each of which is rotatably connected between the two trusses of the buffer frame 14, wherein the leftmost and rightmost second rotating rods 21 are respectively located at inclined positions on the left and right sides of the buffer frame 14 trusses, each of which is fixed with two retarding rollers 2, and the upper part of the second rotating rods 21 is fixedly connected with a transmission wheel 22, and a chain 23 is commonly wound around the transmission wheel 22.

[0040] See also Fig. 9 , and also includes two limiting members 24, which are fixed to the upper rear side of the buffer frame 14, and the two limiting members 24 are respectively located behind the second second rotating rod 21 on the left and the second second rotating rod 21 on the right, and the upper part of the limiting member 24 is squeezed and matched with the chain 23.

[0041] In addition to being hit from the side, the side of a large car may also be scratched, so an anti-scratch mechanism is provided to buffer and protect the side from scratches. The following is its working principle: When a large car is scratched from the side, the retarding roller 2 will first rotate due to the scratch, and the retarding roller 2 will drive the second rotating rod 21 to rotate and then drive the transmission wheel 22 to rotate, and the transmission wheel 22 will drive the chain 23 to start rotating, and the chain 23 will drive other transmission wheels 22 to rotate and then drive other second rotating rods 21 to rotate. The second rotating rod 21 rotates all other retarding rollers 2 to rotate, so as to buffer the scratches from the side, thereby reducing the scratches on the buffer frame 14. The limiting member 24 can be close to the chain 23 to prevent the chain 23 from being separated from the rear side of the second transmission wheel 22 on the left and right sides due to the inclined setting of the left and right sides of the buffer frame 14, thereby preventing the transmission effect between the chain 23 and the transmission wheel 22 from being poor. The above operation can buffer the scratches on the side of a large car, thereby protecting the car's fuel tank and components, and also reducing the scratches on the mechanism.

[0042] See also Figure 10-11 , and also includes a buffer mechanism that can provide buffering when the side guard plate 1 is lowered. The buffer mechanism includes two second fixing members 3, and the second fixing members 3 are respectively fixed to the lower front parts of the left and right fixing frames 11. The second fixing members 3 are slidably connected with buffer members 31, and two third telescopic springs 32 are fixedly connected between the second fixing members 3 and the buffer members 31.

[0043] Because large vehicles often need to refuel or inspect other parts of the vehicle, the side guard plate 1 needs to be lifted. After refueling and inspection are completed, the side guard plate 1 needs to be lowered to reset and lock. When the side guard plate 1 is lowered, excessive rotation may occur. Because the weight of the side guard plate 1 is very heavy, the side guard plate 1 may squeeze the fixing frame 11 when it is turned over and lowered. Therefore, in order to avoid the above situation, a buffer mechanism is provided. The following is its working principle: when people want to refuel and inspect a large vehicle, first remove the nuts 13 on the left and right side pins 12, then remove the pins 12 and rotate the side guard plate 1 counterclockwise upwards, and after the side guard plate 1 is rotated into place, insert the left and right side pins 12 to lock the side guard plate 1, and then people refuel and inspect the large vehicle. When the refueling and inspection of the vehicle are completed After that, people remove the latches 12 on the left and right sides. During the process of removing the latches 12, people need to hold the side guard plate 1 to prevent the side guard plate 1 from suddenly rotating clockwise and injuring people. After removing the latches 12, people rotate the side guard plate 1 clockwise to reset it. Because the weight of the side guard plate 1 is very heavy, the side guard plate 1 will squeeze the fixing frame 11 under the action of inertia. Through the setting of the buffer member 31, the side guard plate 1 will preferentially squeeze the buffer member 31 after being turned over. The buffer member 31 is squeezed and moved backward, and the third telescopic spring 32 is compressed. Under the action of the third telescopic spring 32, the side guard plate 1 will be buffered, thereby reducing the squeezing of the side guard plate 1 on the fixing frame 11. The above operation can be put down, because the gravity and inertia squeeze the fixing frame 11 to play a buffering effect, so that the fixing frame 11 will not be excessively squeezed and damaged.

[0044] See also Figure 12-14 , and also includes a protection mechanism that can perform emergency buffering to protect the oil tank when encountering a severe impact. The protection mechanism includes two air pumps 43. The air pumps 43 are fixed on the left and right sides of the upper part of the side guard plate 1 close to each other. The air pumps 43 are connected to one end of the inflation tube 41, and the other end of the inflation tube 41 is connected to the airbag 4. The airbag 4 is respectively fixed on the left and right sides of the rear part of the side guard plate 1. The third fixing member 42 is fixed on the inflation tube 41. The third fixing member 42 is fixedly connected to the side guard plate 1, and the front side of the third fixing member 42 is fixed to the side guard plate 1.

[0045] See also Fig.13 , and also includes a switch button 44, which is fixed on the left and right sides of the upper part of the side guard plate 11, which are far away from each other. The switch button 44 is electrically connected to the air pump 43 through the control module. The switch button 44 is used to control the corresponding air pump 43 to open and close, and the sliding rod 19 is squeezed and matched with the switch button 44.

[0046] When the side of a large automobile is hit and scratched violently, the buffer frame 14 and the side guard plate 1 will be squeezed and deformed, which will damage the fuel tank and other components, and may cause the fuel tank to explode in severe cases. Therefore, in order to protect the fuel tank when the buffer frame 14 and the side guard plate 1 are squeezed and deformed, thereby reducing the damage to the fuel tank, a protection mechanism is provided. The following is its working principle: When the side of a large automobile is hit and scratched violently, the buffer frame 14 will be squeezed and move backwards, and the buffer frame 14 drives the sliding rod 19 to move backwards. When it moves to the extreme position, the rear of the sliding rod 19 The two ends will be squeezed and contacted with the switch buttons 44. The two switch buttons 44 control the corresponding air pumps 43 to turn on. The air pumps 43 inflate the corresponding airbags 4 through the inflation tubes 41. The airbags 4 expand to protect the fuel tanks and components of the large automobile. When the side of the large automobile is subjected to severe collisions and scrapes, the second telescopic spring 191 moves forward, and the buffer frame 14 drives the sliding rod 19 forward. After the sliding rod 19 moves forward and separates from the switch buttons 44, the airbags 4 will automatically shrink and reset. The above operation can protect the fuel tanks and components in an emergency when the side of the large automobile is subjected to severe collisions and scrapes.

[0047] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
