DETAILED DESCRIPTION
[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] The utility model provides a reinforced rear longitudinal beam mechanism, such as Figure 1 As shown, the mechanism includes: a front longitudinal beam outer plate 1, a front longitudinal beam inner plate 2, a rear longitudinal beam assembly 3 and a reinforcement 4. The end faces of the rear longitudinal beam assembly 3 are respectively connected with the front longitudinal beam outer plate 1 and the front longitudinal beam inner plate 2 to form the entire longitudinal beam portion. The front longitudinal beam inner plate 2 is arranged on the front longitudinal beam outer plate 1 to form the front longitudinal beam assembly. The reinforcement 4 is arranged on the rear longitudinal beam assembly 3 to form a reinforced longitudinal beam, and the reinforcement 4 is close to the connection between the front longitudinal beam outer plate 1 and the rear longitudinal beam assembly 3. The reinforcement 4 is arranged on the rear longitudinal beam assembly 3 to form a reinforced longitudinal beam, thereby improving the strength of the entire mechanism, and the reinforcement 4 is close to the connection between the front longitudinal beam outer plate 1 and the rear longitudinal beam assembly 3, so that the reinforcement 4 is close to the middle position of the entire beam, increasing the structural strength of the middle position of the beam, and can also be buffered by the reinforcement 4 when a collision occurs, reducing the energy transmitted to the vehicle body, and improving the safety of the driver and passengers. It should be noted that when a vehicle travels on a bumpy road, part of the road energy will be transmitted through the longitudinal beam, so that the reinforcement portion 4 can change the modal frequency of the longitudinal beam assembly, reduce the impact of the road on the driver and passengers, and improve the comfort of the driver and passengers.
[0023] In one embodiment, the reinforcement part 4 includes a rear longitudinal beam reinforcement body 42 and a reinforcement covering colloid 43, wherein the reinforcement covering colloid 43 is arranged on the rear longitudinal beam assembly 3, and the longitudinal beam reinforcement body is arranged on the reinforcement covering colloid 43. It should be noted that there is adhesive on the reinforcement covering colloid 43, and the adhesive on the reinforcement covering colloid 43 is heated and deformed during high-temperature baking in a workshop, and the rear longitudinal beam reinforcement body 42 is tightly adhered together, and the high temperature causes the rear longitudinal beam reinforcement body 42 and the longitudinal beam assembly 3 to undergo certain plastic deformation, and the rear longitudinal beam reinforcement body 42 is perfectly combined with the rear longitudinal beam assembly 3 without falling off.
[0024] In one embodiment, the material of the rear longitudinal beam reinforcement body 42 is polyamide 66 or nylon 66 and glass fiber. It should be noted that polyamide 66 is easy to shape during processing, has good conformability, and has low requirements on size and technology. Therefore, the production cost is low and the production efficiency is high. In addition, compared with the previous metal reinforcement plate structure, the weight is lighter. The rear longitudinal beam reinforcement body 42 is covered with glue when it is produced. After being heated and expanded, it can be well fixed with the front longitudinal beam outer plate 1 and the rear longitudinal beam inner plate.
[0025] In one embodiment, a plurality of crisscross reinforcing ribs are provided on the rear longitudinal beam reinforcing body 42. The plurality of reinforcing ribs can strengthen the structure of the rear longitudinal beam reinforcing body 42, and when a collision occurs, the plurality of reinforcing ribs can further buffer the energy generated during the collision, thereby improving safety.
[0026] In one embodiment, multiple rectangular structures or triangular structures are formed between multiple reinforcing ribs on the rear longitudinal beam reinforcement body 42. It should be noted that when a vehicle collides, multiple rectangular structures or triangular structures on the rear longitudinal beam reinforcement body 42 are flattened in rows, and absorb energy through deformation and destruction, firstly ensuring that the collision energy is transmitted to the vehicle body end, and secondly also strengthening the strength of the rear longitudinal beam, thereby ensuring the safety of the driver and passengers.
[0027] In one embodiment, a reinforcement groove 31 is provided on the rear longitudinal beam assembly 3, and a strong covering colloid is laid in the reinforcement groove 31 so that the rear longitudinal beam reinforcement body 42 is filled in the reinforcement groove 31. The rear longitudinal beam reinforcement body 42 is fixed by the reinforcement groove 31, so that the rear longitudinal beam reinforcement body 42 is not easy to fall off, thereby strengthening the strength of the overall structure.
[0028] In one embodiment, the beam reinforcement body and the reinforcement covering colloid 43 are provided with a connecting fixing hole 41, so that the rear longitudinal beam reinforcement body 42 and the reinforcement covering colloid 43 are fixed in the reinforcement groove 31. It should be noted that the rear longitudinal beam reinforcement body 42 and the reinforcement covering colloid 43 are tightly fixed in the reinforcement groove 31 by the studs or screws screwed in the fixing hole 41, and the colloid of the reinforcement covering colloid 43 is added, so that the rear longitudinal beam reinforcement body 42 and the reinforcement covering colloid 43 can be fixed in the reinforcement groove 31 more stably.
[0029] In one embodiment, the front longitudinal beam inner plate 2 is in a V-shaped structure, so that a fixed space is formed between the front longitudinal beam inner plate 2 and the front longitudinal beam outer plate 1. The fixed space formed between the front longitudinal beam inner plate 2 and the front longitudinal beam outer plate 1 can accommodate other components on the front longitudinal beam outer plate 1, and can also increase the structural stability between the front longitudinal beam inner plate 2 and the front longitudinal beam outer plate 1, and indirectly improve the strength of the structure.
[0030] In one embodiment, the end faces of the rear longitudinal beam assembly 3 are respectively welded to the front longitudinal beam outer plate 1 and the front longitudinal beam inner plate 2, and the front longitudinal beam inner plate 2 and the front longitudinal beam outer plate 1 are fixed by screws. It should be noted that corresponding screw holes are provided at both ends of the front longitudinal beam inner plate 2 and the front longitudinal beam outer plate 1, and the screws are fixed in the screw holes so that the front longitudinal beam inner plate 2 and the front longitudinal beam outer plate 1 are tightly combined. Of course, in addition to the screw and hole fixing method, welding can also be used to connect the front longitudinal beam inner plate 2 and the front longitudinal beam outer plate 1.
[0031] The utility model also provides a vehicle beam structure, including a reinforced rear longitudinal beam mechanism. The overall structure of the reinforced rear longitudinal beam mechanism is strengthened, thereby strengthening the vehicle beam structure and improving the safety of the entire vehicle.
[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
