Description

Technical Field

[0001] The utility model relates to the field of reinforcing beams, in particular to an inner reinforcing beam body of a front longitudinal beam of an automobile. Background Art

[0002] The inner reinforcement beam of the front longitudinal beam of an automobile is a structural component that enhances the strength and stability of the front longitudinal beam of an automobile. The inner reinforcement beam of the front longitudinal beam of an automobile is located on the inner side of the front longitudinal beam and is tightly connected to the front longitudinal beam through connecting bolts or other fixing methods. The reinforcement beam is usually made of high-strength steel plates with excellent tensile strength and impact resistance. Its tensile strength is generally between 510 and 780 MPa, or even higher, to ensure that the front longitudinal beam of the automobile can be adequately protected in extreme situations such as vehicle collisions.

[0003] In the prior art, the inner reinforcing beam of the front longitudinal beam of an automobile generally protects the front longitudinal beam of the automobile by its own material properties. Since the overall structure of the reinforcing beam is relatively simple, after the front longitudinal beam of the automobile is hit, the reinforcing beam installed on the inner side of the front longitudinal beam of the automobile cannot effectively buffer and share the impact force. The impact force is not only easily transmitted to the front longitudinal beam of the automobile through the reinforcing beam and affects it, but the reinforcing beam is also easily deformed and its own service life is reduced, thereby reducing the protective effect on the front longitudinal beam of the automobile. Utility Model Content

[0004] The main purpose of the utility model is to provide an inner side reinforcing beam body of a front longitudinal beam of an automobile, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A reinforcing beam body inside a front longitudinal beam of an automobile comprises a reinforcing beam body, a buffer mechanism is provided at the front end of the reinforcing beam body, and the buffer mechanism comprises reinforcing ribs, a fixing tube, a fixing rod, a first buffer spring, a buffer ring, a connecting ring, a fixing disk, a second buffer spring, a buffer sleeve and a buffer plate, a plurality of reinforcing ribs are fixedly connected inside the reinforcing beam body, and the fixing tube is fixedly connected to the front end of the reinforcing ribs, the fixing rod is fixedly connected inside the fixing tube, and the first buffer spring is sleeved on the outside of the fixing rod, the buffer ring is fixedly connected to the front end of the first buffer spring, the connecting ring is fixedly connected to the fixing tube via a connecting ring on an inner ring wall, a buffer sleeve is fixedly connected to the rear end wall of the fixing disk, and the second buffer spring is sleeved on the outside of the buffer sleeve and fixes the connector between the fixing disk and the connecting ring, and the buffer plate is fixedly connected to the fixing disk via a nut.

[0007] Preferably, a plurality of through holes are fixedly connected to the front end wall of the reinforcing beam body.

[0008] Preferably, a plurality of reinforcing ribs corresponding to the through holes are fixedly installed inside the reinforcing beam body, and a fixing tube is fixedly installed on the front end wall of the reinforcing ribs. The fixing tube passes through the through hole, and an external thread is provided on the front end of the outer wall of the fixing tube.

[0009] Preferably, the fixing rod is fixedly mounted on the inner bottom surface of the fixing cylinder, and the first buffer spring is sleeved on the rod body of the fixing rod, the rear end of the first buffer spring is fixedly mounted on the inner bottom surface of the fixing cylinder, and the front end of the first buffer spring is fixedly mounted with a buffer ring, and the buffer ring is movably sleeved on the rod body of the fixing rod.

[0010] Preferably, an internal thread is provided on the inner wall of the connecting ring, and the internal thread is threadedly connected with the external thread, a buffer sleeve is fixedly installed on the rear end wall of the fixed disk, and the buffer sleeve is inserted and installed in the fixed sleeve, the fixed rod is inserted and installed in the buffer sleeve, the second buffer spring is sleeved on the outside of the buffer sleeve and fixedly installed between the connecting ring and the fixed disk, and a threaded short rod is also fixedly installed on the front end wall of the fixed disk.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, the buffer mechanism is used in conjunction with the reinforcing beam body. When the reinforcing beam body is hit, the buffer plate in front of the reinforcing beam body will bear the impact force in advance and move backwards. When moving, it will force the second buffer spring installed between the fixed plate and the connecting ring to perform a retraction operation. The impact force received by the buffer plate is absorbed and buffered by the elastic deformation of the second buffer spring. At the same time, the buffer sleeve at the rear end of the fixed plate will push the buffer ring backwards in the fixed cylinder along the fixed rod, so that when the buffer ring moves backwards along the fixed rod, it forces the first buffer spring on the fixed rod to perform a retraction operation. Elastic deformation can further absorb and buffer the impact force received by the buffer plate, so that the reinforcement beam body has a double buffering effect when it is hit, and can effectively buffer and share the impact force, avoiding the impact force being directly transmitted to the reinforcement beam body and then transmitted to the front longitudinal beam of the automobile through the reinforcement beam body, and by adding a number of reinforcement ribs inside the reinforcement beam body, the strength of the reinforcement beam body itself can be further improved, which can not only improve the strength of the reinforcement beam body and prevent the reinforcement beam body from deformation, but also increase the service life of the reinforcement beam body, thereby achieving the purpose of improving the protection effect on the front longitudinal beam of the automobile.
