[0026] The following specific embodiments illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification.

[0027] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this application. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness or purpose of this application, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms such as "front," "back," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this application. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this application.

[0028] It should be noted that the front end of the front longitudinal beam of a car refers to the area where the front end of the front longitudinal beam connects to the energy-absorbing box. If the front end area of ​​the front longitudinal beam is damaged, the energy-absorbing box cannot perform its energy-absorbing function. The front end of the front longitudinal beam is one of the most critical force-bearing points in collision safety and is also the first structure to be stressed, receiving enormous impact forces. In order to ensure that the front longitudinal beam has high strength, it is not only necessary to ensure that the front end of the front longitudinal beam can effectively absorb some of the energy generated by the collision under large impact forces, but also to ensure that the front end area of ​​the front longitudinal beam does not tear during the collision, so as to ensure the integrity of the front longitudinal beam. In daily use or collision tests, vehicles will face some small offset collisions, in which case the front longitudinal beam on one side will be stressed. This condition is extremely severe, mainly because the structure of the front end area of ​​the front longitudinal beam has low strength and is prone to tearing, which can lead to the tearing or even failure of the entire front longitudinal beam.

[0029] Please see Figures 1 to 6 This application exemplarily provides a side-slip structure for a front longitudinal beam of an automobile. The front longitudinal beam 11 includes an outer plate 1 and an inner plate 2. The front longitudinal beam 11 is connected to an energy-absorbing box. The side-slip structure includes:

[0030] Side slider 3 is mounted on outer plate 1, and a guide surface 4 is provided on the side of side slider 3 away from outer plate 1;

[0031] Connector 5 passes through the inner plate 2, the outer plate 1 and the side slider 3 in sequence, and connects the side slider 3 to the outer plate 1.

[0032] In the side-slip structure provided in this application, the inner plate 2 and outer plate 1 of the front longitudinal beam 11 of the automobile are further connected by the connector 5, and the side slider 3 is connected to the outer plate 1. When the front longitudinal beam 11 on one side is impacted, the obstacle impacted is guided and deflected by the guide surface 4 of the side slider 3, so as to avoid the situation of excessive force on the front longitudinal beam 11 on one side, reduce the risk of tearing of the front longitudinal beam 11, and improve the safety of the whole vehicle.

[0033] Understandably, the side slider 3 of this application is located on the front longitudinal beam 11 of the vehicle near the front port. Since the front port area is prone to tearing due to excessive impact force during a collision, the side slider 3 guides and deflects the impacting obstacle, reducing the force on the front port of the front longitudinal beam 11, thereby reducing the force on one side of the front longitudinal beam 11, and thus reducing the risk of tearing of the front longitudinal beam 11. This mitigates the situation where the front longitudinal beam 11 of the vehicle is impacted on one side in the event of a minor collision, thereby improving the overall safety performance of the vehicle.

[0034] In this embodiment, the connector 5 is configured as a cylindrical tube sleeve structure, and a reinforcing member 6 is also sleeved on the tube sleeve structure. The reinforcing member 6 has a Z-shaped structure, and the ear 12 of the reinforcing member 6 is located on the side of the inner plate 2 near the outer plate 1. Specifically, the ear 12 of the reinforcing member 6 is fixedly connected to the inner plate 2. The inner plate 2 and the outer plate 1 of the front longitudinal beam 11 of the automobile are further reinforced and connected by the connector 5, which improves the structural strength of the front end area of ​​the front longitudinal beam 11 of the automobile and further reduces the risk of tearing of the front longitudinal beam 11 in a collision. Through the Z-shaped structure design of the reinforcing member 6, the overlap stability between the connector 5 and the inner plate 2 of the front longitudinal beam 11 is effectively enhanced, and the structural strength is improved.

[0035] In the above embodiment, the connector 5 is provided with a reinforcing boss 7 at one end near the inner plate 2. The reinforcing boss 7 is located between the reinforcing member 6 and the inner plate 2 and surrounds the circumference of the connector 5. Since the connector 5 is a hollow cylindrical tube sleeve structure, the reinforcing boss 7 can reduce stress concentration in the connector 5 when it is installed by the fastener 9 or when it is impacted, thereby improving the connection stability between the connector 5 and the front longitudinal beam 11.

[0036] In some embodiments, the guide surface 4 is set as an inclined surface, the side slider 3 has a triangular cross section, and the thickness of the side slider 3 gradually increases along the length of the outer plate 1 and toward the side away from the energy absorption box. Specifically, the cross section of the side slider 3 is designed as an approximately right-angled triangle, and the side slider 3 adopts a gradually thickening triangular structure to form an inclined guide surface 4, which can effectively deflect the colliding object along the guide surface 4 in the event of a small offset collision, and slide it away along the guide surface 4, avoiding the risk of a huge impact force on the single-sided front longitudinal beam 11.

[0037] In this embodiment, a reinforcing structure 8 is provided on the guide surface 4. The reinforcing structure 8 is a Y-shaped structure. Specifically, fasteners 9 are provided on the guide surface 4 in the area enclosed by the reinforcing structure 8. The fasteners 9 are used to connect the side slider 3 to the outer plate 1 and the connector 5 respectively. Each side of the Y-shaped structure corresponds to a fastener 9 mounting position. The fasteners 9 form an isosceles triangle arrangement, which can improve the installation stability of the side slider 3 and ensure that it can play a side sliding role in the event of a collision. The fasteners 9 pass through the connector 5 to connect the inner plate 2 and the outer plate 1 of the front longitudinal beam 11, thereby improving the structural strength of the front end of the front longitudinal beam 11. The fasteners 9 can be bolts, screws, nuts and other components that can be used for connection and installation. This is not limited to these.

[0038] In another embodiment, this application also provides a front longitudinal beam 11 for automobiles, which includes an outer plate 1 and an inner plate 2. The front longitudinal beam 11 is connected to an energy-absorbing box and also includes the side-slip structure described above.

[0039] In some embodiments, the front longitudinal beam 11 of the vehicle also includes a connecting plate 10 for connecting the front longitudinal beam 11 of the vehicle to the energy-absorbing box. The connecting plate 10 is provided with a welding inlay 13, which is welded to the inner wall of the front end of the front longitudinal beam 11, that is, the welding inlay 13 is welded to the inner plate 2 and the outer plate 1. By welding the welding inlay 13 to the periphery of the inner wall of the front end of the front longitudinal beam 11, the structural strength of the front end of the front longitudinal beam 11 is further improved, and tearing due to impact is prevented. Specifically, the energy-absorbing box and the connecting plate 10 are connected by bolts, thereby realizing the connection between the front longitudinal beam 11 and the energy-absorbing box.

[0040] In some embodiments, the cross-sectional width of the front end of the front longitudinal beam 11 is greater than the cross-sectional width of the rear end of the front longitudinal beam 11. Specifically, the cavity in the front end region of the front longitudinal beam 11 is formed by an inner plate 2 and an outer plate 1. The cross-sectional width of the cavity in the front end is greater than the cross-sectional width of the rear end, which can effectively improve the structural rigidity of the front end region of the front longitudinal beam 11.

[0041] In another embodiment, this application also provides a vehicle, such as the aforementioned front longitudinal beam 11.

[0042] In summary, in the front longitudinal beam of the automobile provided in this application, the inner plate 2 and the outer plate 1 of the front longitudinal beam 11 are further connected by the connector 5, and the side slider 3 is connected to the outer plate 1. When the front longitudinal beam 11 on one side is impacted, the guide surface 4 of the side slider 3 guides the impacting obstacle to deflect, thereby avoiding excessive force on the front longitudinal beam 11 on one side, reducing the risk of tearing of the front longitudinal beam 11, and improving the overall vehicle safety.

[0043] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
