Description

Technical Field

[0001] The present invention relates to the technical field of automotive anti-collision beams, and specifically relates to an automotive anti-collision beam capable of increasing the impact protection area and a using method thereof. Background Technique

[0002] An anti-collision beam is a device used to absorb collision energy when a vehicle is impacted. It consists of a main beam, an energy-absorbing box, and a mounting plate connecting the vehicle. Both the main beam and the energy-absorbing box can effectively absorb collision energy during a low-speed collision of the vehicle, minimizing the damage to the vehicle's longitudinal beam caused by the impact force as much as possible, thereby playing its protective role for the vehicle.

[0003] When a traditional automotive anti-collision beam is in use, it is usually directly installed on the vehicle frame through an energy-absorbing box. Since the protection area of the automotive anti-collision beam is usually fixed and unchanged, and for the aesthetics of the vehicle, the volume of the anti-collision beam is usually small, resulting in a poor protection effect of the automotive anti-collision beam, and in the event of a severe impact accident, the vehicle is prone to catch fire. Therefore, an automotive anti-collision beam capable of increasing the impact protection area and a using method thereof are proposed. Summary of the Invention

[0012] Preferably, one end of each of the two guide posts penetrates through the inner side wall of the sleeve and is fixedly connected to a limit plate. A third spring is fixedly connected to one side of the limit plate, and one end of the third spring is fixedly connected to the inner side wall of the sleeve. Two energy absorption box bodies are symmetrically and fixedly connected to the rear surface of the front anti-collision beam, and one side of each of the two energy absorption box bodies is fixedly connected to the front surface of the vehicle frame; the moving guide posts drive the limit plates to move, and the moving limit plates drive the third springs to be compressed, so that the compressed third springs unload the force on the front anti-collision beam again.

[0013] A method for using an automobile anti-collision beam that can increase the impact protection area includes the following steps:

[0014] S1.

An acrylic plate body 43 is fixedly connected to the inner side wall of the groove 42; by driving the support block 41 to move through the front anti-collision beam 101, the moving support block 41 squeezes the acrylic plate body 43, thereby breaking the acrylic plate body 43.

[0033] In this embodiment, specifically: a liquid storage bag 45 is fixedly connected to the inner side wall of the groove 42, and drainage holes 44 are evenly formed in the outer side wall of the vehicle frame 103; the sprayed flame retardant liquid is diverted through the drainage holes 44.

[0035] In this embodiment, specifically: one end of the two guide posts 104 penetrates through the inner side wall of the sleeve 105 and is fixedly connected with a limit plate 46, a third spring 47 is fixedly connected to one side of the limit plate 46, one end of the third spring 47 is fixedly connected to the inner side wall of the sleeve 105, two energy absorption box bodies 102 are symmetrically and fixedly connected to the rear surface of the front anti-collision beam 101, and one side of the two energy absorption box bodies 102 is fixedly connected to the front surface of the vehicle frame 103; the moving guide post 104 drives the limit plate 46 to move, the moving limit plate 46 drives the third spring 47 to be compressed, and thus the compressed third spring 47 unloads the force on the front anti-collision beam 101 again.

[0036] A method for using an automobile anti-collision beam that can increase the impact protection area includes the following steps:

[0037] S1. Under the action of the impact force, the T-shaped shaft rod 201 drives the first spring 205 to be compressed, so that the T-shaped shaft rod 201 slides in the T-shaped chute 204, and then the compressed second spring 206 drives the arc-shaped baffle 202 to move upward; the compressed second spring 206 drives the arc-shaped baffle 202 to move, so as to pop the arc-shaped baffle 202 out of the vehicle frame 103 and the front anti-collision beam 101, increasing the protection area of the front anti-collision beam 101, improving the anti-collision effect, and not affecting the aesthetics of the vehicle.

[0038] S2. The front anti-collision beam 101 drives the guide post 104 to move, and the moving guide post 104 guides the front anti-collision beam 101 by sliding in the sleeve 105.

[0039] S3. The moving guide post 104 drives the limit plate 46 to move, and the moving limit plate 46 drives the third spring 47 to be compressed.

[0040] S4. The moving front anti-collision beam 101 drives the support block 41 to move, the moving support block 41 squeezes and breaks the acrylic plate body 43, and then the moving support block 41 squeezes and ruptures the liquid storage bag 45, so that the flame retardant stored in the liquid storage bag 45 is sprayed out, and then the flame retardant is diverted through the drainage holes 44.

[0041] In this embodiment, specifically: in S2, the moving front bumper beam 101 drives the energy-absorbing box body 102 to move, and the moving energy-absorbing box body 102 deforms by extruding the vehicle frame 103; the energy-absorbing box body 102 absorbs the impact force received by the front bumper beam 101, thereby performing the work of unloading the force on the front bumper beam 101.

[0042] When the present invention is working: when a vehicle collides, the T-shaped shaft rod 201 drives the first spring 205 to move under the action of the impact force. The moving first spring 205 is compressed by extruding the front bumper beam 101, so that the T-shaped shaft rod 201 slides in the T-shaped chute 204. Then, the compressed second spring 206 drives the arc-shaped baffle 202 to move. The moving arc-shaped baffle 202 drives the guide block 48 to move. The moving guide block 48 slides in the guide groove 49 to guide the arc-shaped baffle 202, avoiding the deviation of the arc-shaped baffle 202 during work. Thus, the arc-shaped baffle 202 is ejected from the vehicle frame 103 and the front bumper beam 101, increasing the protection area of the front bumper beam 101 and improving the anti-collision effect. At the same time, the front bumper beam 101 drives the guide post 104 and the energy-absorbing box body 102 to move under the action of the impact force. The moving energy-absorbing box body 102 deforms by extruding the vehicle frame 103 to perform the preliminary work of unloading the force on the front bumper beam 101. Then, the moving guide post 104 slides in the sleeve 105 to guide the front bumper beam 101. At the same time, the moving guide post 104 drives the limiting plate 46 to move, and the moving limiting plate 46 drives the third spring 47 to be compressed. Thus, the compressed third spring 47 unloads the force on the front bumper beam 101 again, further improving the protection effect of the bumper beam. When a severe collision accident occurs, the front bumper beam 101 drives the support block 41 to move. The moving support block 41 extrudes the acrylic plate body 43, thereby breaking the acrylic plate body 43. Then, the moving support block 41 extrudes the liquid storage bag 45, so that the flame retardant liquid stored in the liquid storage bag 45 is ejected. Then, the drainage hole 44 guides the ejected flame retardant liquid, thereby avoiding the occurrence of vehicle combustion. This device not only increases the protection area of the bumper beam and improves the protection effect, but also avoids the occurrence of vehicle combustion, further improving the protection effect on the vehicle and increasing the safety guarantee of the driver.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
