Description

Technical Field

[0001] The utility model relates to the technical field of metal beams, and in particular to an anti-fracture and ejection integrated crossbeam structure. Background Art

[0002] As a common load-bearing structure, metal beams are widely used in some vehicles and mechanical equipment.

[0003] When the beam is subjected to a strong impact, it will bend and deform along the direction of the impact. The impact force will be converted into elastic potential energy of the beam through the deformation of the beam. In this way, when the beam breaks, it will rebound in the opposite direction of the impact under the action of the accumulated elastic potential energy. In this way, it is easy to accidentally injure nearby equipment or people during the rebound process. Therefore, this type of beam needs to be improved. Utility Model Content

[0020] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0021] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operate in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0022] See also Figure 1-3 As shown, this embodiment provides an anti-fracture ejection integrated crossbeam structure, which can be used in vehicles or mechanical equipment, such as a load-bearing beam of an impact test equipment.

[0023] This embodiment includes a beam body 1 extending along a first direction, two mounting parts 2, and a blocking cable 3. The first direction here can be understood as the length direction of the beam; accordingly, for the convenience of explanation, the direction horizontally perpendicular to the first direction is recorded as the second direction.

[0024] The two mounting parts 2 are respectively fixed at two ends of the beam body 1 , and the mounting parts 2 serve as mounting parts 2 for mounting the beam body 1 on a predetermined carrier.

[0025] The beam body 1 is denoted as the front side or the front side, and the other side is denoted as the back side or the back side. Generally, the front side of the beam faces the side receiving the impact force and is used as the collision side. The beam body 1 is preferably made of hard metal, such as steel.

[0026] The blocking cable 3 is located on the back side of the beam body 1 and its two ends are respectively fixed on the two mounting parts 2, wherein the blocking cable 3 is in a tensioned state; the blocking cable 3 is preferably a steel cable.

[0027] The back side of the beam body 1 is provided with a plurality of first ribs 4 which are sequentially distributed along the length direction of the beam body 1 and have through openings 41 , and the blocking cables 3 pass through the through openings 41 along the first direction.

[0028] The function of the arresting cable 3 is to prevent the beam 1 from rebounding significantly after the beam 1 breaks. Specifically, when the front of the beam 1 is subjected to an impact force from the first direction, the beam 1 will continuously bend backward along the first direction to store energy. When the beam 1 bends and breaks, the beam 1 will release elastic potential energy and rebound along the first direction. When the beam 1 rebounds to a certain position (the position where the arresting cable 3 and the first rib plate 4 collide), the first rib plate 4 cannot continue to rebound with the beam 1 under the obstruction of the arresting cable 3, thereby limiting the continued rebound of the beam 1, thereby reducing the risk of the beam 1 damaging nearby equipment or people due to excessive rebound. This is equivalent to preventing the large rebound of the beam 1 by the arresting cable 3 during the rebound process of the beam 1 breaking.

[0029] In addition, in this embodiment, in order to improve the anti-collision performance of the entire crossbeam, in this embodiment, one side of the first rib plate 4 is provided with a friction plate 5 that fits tightly against the first rib plate 4, and the friction plate 5 is preferably a steel plate.

[0030] The friction plate 5 can slide along the second direction relative to the first rib plate 4, wherein the second direction is perpendicular to the first direction; the friction plate 5 is fixed to the blocking cable 3 or the blocking cable 3 movably passes through the friction plate 5; the through opening 41 has an extension in the second direction, so that the blocking cable 3 can have space to move in the through opening 41 along the second direction relative to the first rib plate 4.

[0031] In this embodiment, the cooperation between the first rib plate 4 and the friction plate 5 is equivalent to forming an energy-consuming structure, which consumes energy by the friction force between the two. Specifically: the first rib plate 4 and the beam body 1 remain relatively still, and the blocking cable 3 and the friction plate 5 basically remain relatively still in the first direction; when the beam body 1 is impacted, there is a tendency for the first rib plate 4 and the friction plate 5 to move relative to each other along the first direction. During this process, a large friction resistance will be formed between the two. The friction resistance is relied upon to consume the impact on the beam body 1 to achieve energy consumption, which is beneficial to improving the anti-collision performance of the entire beam.

[0032] In this embodiment, a through hole 52 is provided on the friction plate 5, and the blocking cable 3 passes through the friction plate 5 through the through hole 52. The size of the through hole 52 is substantially the same as that of the Zura cable.

[0033] The friction plate 5 and the first rib plate 4 are pressed against each other by a locking assembly. Specifically, the locking assembly includes a screw rod 61 fixed to the first rib plate 4 on the side close to the friction plate 5, and a nut 62 that can be threadedly connected to the screw rod 61; a guide groove 51 extending along the second direction is provided on the friction plate 5, the screw rod 61 passes through the guide groove 51 along the first direction, and the nut 62 is threadedly connected to the screw rod 61 and presses the friction plate 5 against the first rib plate 4 along the first direction.

[0034] In addition, in order to improve the connection strength between the mounting portion 2 and the beam body 1 , in this embodiment, a plurality of second ribs 7 are provided between the mounting portion 2 and the beam body 1 .

[0035] In this embodiment, the mounting portion 2, the beam body 1, the first rib plate 4 and the second rib plate 7 are an integrated structure and are all made of steel to improve the strength of the entire beam.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
