Description

Technical Field

[0001] The invention relates to the technical field of automobiles, and in particular to a cabin upper side beam reinforcement structure. Background Art

[0002] Traffic accidents caused by collisions between vehicles and pedestrians, vehicles, etc. usually cause great harm to pedestrians and drivers, resulting in serious consequences. With the popularization of vehicles, the safety performance of vehicles is becoming more and more important. Through research on vehicle traffic accidents, countries are constantly improving vehicle collision regulations and improving vehicle market access conditions. Among them, in 100% frontal collisions and offset collisions, the front cabin structure is required to guide and absorb the collision energy generated during the vehicle collision process, reduce the deformation of the passenger compartment, and reduce the damage to the occupants.

[0003] In a frontal collision of a vehicle, the upper side beam of the engine compartment serves as a force transmission path for the upper part of the engine compartment, absorbing collision energy and transmitting collision energy to the body side parts. In a high-speed collision, the above-mentioned design defect will cause the body side A-pillar 1 to be severely deformed, and the body parts will invade the passenger compartment, causing occupant injuries. At the same time, the doors and windows will be deformed and difficult to open. To this end, we propose a cabin upper side beam reinforcement structure. Summary of the invention

[0004] The object of the present invention is to provide a cabin upper side beam reinforcement structure to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a cabin upper side beam reinforcement structure, comprising an A-pillar and a cabin upper side beam, a reinforcement tripod is installed on one side of the A-pillar and the cabin upper side beam, the reinforcement tripod comprises a first frame and a second frame, the second frame comprises a first support rod and a second support rod, one end of the first support rod and the second support rod are both sleeved on the outside of the pin shaft, the other end of the first support rod and the second support rod are both installed with a linkage rod, a piston head is installed on the end of the linkage rod, a compression spring is provided on one side of the piston head, the compression spring, the linkage rod and the piston head are all inserted into the inside of a through hole, and the through hole is opened at one end of the first frame.

[0006] Preferably, a sealing sleeve is sleeved on the outside of the linkage rod.

[0007] Preferably, a U-shaped opening is formed at one end of the first support rod, and the second support rod is located inside the U-shaped opening.

[0008] Preferably, limit blocks are welded on both ends of the pin shaft.

[0009] Preferably, screw holes are provided at the three corners of the reinforced tripod.

[0010] Preferably, one end of each of the first support rod and the second support rod is provided with a through hole matching the pin shaft.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The present invention installs a reinforcing tripod on one side of the A-pillar and the cabin upper side beam. When the vehicle collides, part of the force received by the cabin upper side beam is transmitted to the lower section of the A-pillar through the cabin upper side beam, and part of the force is transmitted to the lower section of the A-pillar through the reinforcing tripod, thereby adding a transmission channel and increasing the stability of the cabin upper side beam during the collision process. By adding the reinforcing tripod, the stiffness of the shock absorber in three directions is increased, especially the stiffness in the Z direction. When the shock absorber installation point is subjected to force in the Z direction, the reinforcing tripod plays a supporting role, thereby greatly increasing the stiffness in the Z direction of the shock absorber installation point;

[0013] 2. The present invention divides the reinforced tripod into a first frame and a second frame. The first support rod and the second support rod in the second frame are inserted into the through hole at the end of the first frame through a linkage rod and a compression spring. The compression spring is beneficial for absorbing impact force when a collision occurs. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Specifically, a sealing sleeve 13 is sleeved on the outside of the linkage rod 12. The sealing sleeve 13 can prevent dust and water from entering the through hole 9 and causing corrosion of the compression spring 10.

[0021] Specifically, a U-shaped opening 14 is formed at one end of the first support rod 6, and the second support rod 7 is located inside the U-shaped opening 14. The U-shaped opening 14 facilitates the installation of the second support rod 7, so that when the second support rod 7 and the first support rod 6 are butt-jointed with both ends of the first frame 4, there will be no misalignment.

[0022] Specifically, both ends of the pin shaft 8 are welded with limit blocks 15. The limit blocks 15 can prevent the second support rod 7 and the first support rod 6 from falling off from the pin shaft 8.

[0025] Working principle: When in use, the first support rod 6 and the second support rod 7 are sleeved on the pin shaft 8, so that when the compression spring 10 is compressed, the first support rod 6 and the second support rod 7 can rotate, so that the compression spring 10 absorbs the impact, and then the linkage rod 12 and the compression spring 10 at the other ends of the first support rod 6 and the second support rod 7 are inserted into the through hole 9 at the end of the first frame 4 to form a reinforced tripod 3 as a whole, and then the reinforced tripod 3 is installed on the A-pillar 1 and the cabin upper side beam 2 by bolts. When the vehicle collides, part of the force received by the cabin upper side beam 2 is transmitted to the lower section of the A-pillar 1 through the cabin upper side beam 2, and part of it is transmitted to the lower section of the A-pillar 1 through the reinforced tripod 3, thereby adding a transmission channel and increasing the stability of the cabin upper side beam 2 during the collision.
