Abstract
Description
Technical Field
[0001] This application relates to the field of automotive component technology, and in particular to a high-strength, deformation-resistant automotive crossbeam. Background Technology
[0002] Automotive crossbeams need to have high strength to resist deformation. The performance of the automotive crossbeams greatly affects the vehicle's ability to resist impact deformation. In order to improve the strength of automotive crossbeams, in addition to using high-performance materials, the material thickness is also increased. However, increasing the material thickness will increase the weight of the crossbeam, thus deviating from the pursuit of vehicle lightweighting and making the vehicle consume more energy when driving. Summary of the Invention
[0003] The purpose of this application is to provide a deformation-resistant automotive crossbeam that combines lightweight and high strength.
[0004] To achieve the above objectives, this application provides a high-strength, deformation-resistant automotive crossbeam: comprising a longitudinal beam plate, wherein the upper and lower edges of the longitudinal beam plate are provided with crossbeam plates, and a rib plate is fixedly connected between two crossbeam plates, wherein the rib plate is fixedly connected to the longitudinal beam plate, positioning holes are provided at both ends of the longitudinal beam plate, and a plurality of longitudinal connecting holes are provided on the crossbeam plate for connecting parts to pass through so that the automotive crossbeam is connected to other parts of the vehicle frame.
[0005] As a preferred embodiment, the main body of the longitudinal beam plate is a long longitudinal plate, and the two ends of the long longitudinal plate are connected to short longitudinal plates by inclined longitudinal plates, thereby improving the longitudinal beam plate's resistance to deformation in the vertical direction.
[0006] As a preferred embodiment, both short longitudinal plates are parallel to the long longitudinal plate, and the positioning holes are formed in the short longitudinal plates to allow the connecting members to pass through both ends of the constrained longitudinal beam plate.
[0007] As a preferred embodiment, the main body of the crossbeam plate is a long crossbeam plate, and the two ends of the long crossbeam plate are connected to short crossbeam plates by inclined crossbeam plates. The extension direction of the crossbeam plate along the horizontal plane is the same as the extension direction of the longitudinal beam plate along the horizontal plane.
[0008] As a preferred embodiment, the edge of the long horizontal plate is connected to the edge of the long vertical plate, the edge of the oblique horizontal plate is connected to the edge of the oblique vertical plate, and the edge of the short horizontal plate is connected to the edge of the short vertical plate. In fact, the longitudinal beam plate and the horizontal beam plate are integrally formed by stamping or die casting.
[0009] As a preferred embodiment, at least one of the two inclined crossbeams is fixedly connected to a bridging plate, and the bridging plate is also integral with the crossbeam.
[0010] As a preferred embodiment, the long longitudinal plate has several ribs between it and the two long transverse plates, the oblique longitudinal plate has at least two ribs between it and the two connected oblique transverse plates, and the short longitudinal plate has at least two ribs between it and the two connected short transverse plates. This can effectively improve the structural stability of the longitudinal beam plate and the transverse beam plate, so that the entire automobile transverse beam has higher strength to resist deformation.
[0011] As a preferred embodiment, the longitudinal beam plate has a first mounting plate at both ends, and the first mounting plate has a vertical connecting hole; the crossbeam plate has a second mounting plate at both ends, and the second mounting plate has a horizontal connecting hole, for the connecting parts at both ends of the crossbeam to pass through and connect with other frame structures.
[0012] Compared with the prior art, the beneficial effects of this application are as follows:
[0013] (1) By designing a beam-plate structure with a C-shaped cross section and arranging a rib structure with an arc between the beam-plate structures, the car crossbeam has high structural strength to resist deformation, while not increasing the weight of the car crossbeam, thus maintaining the lightweight of the vehicle.
[0014] (2) By opening multiple connection holes on the beam plate, the weight of the crossbeam is further reduced while ensuring the structural strength, and at the same time, it is convenient to connect the crossbeam with other parts of the car frame. Attached Figure Description

[0022] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0023] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0024] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0025] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.
[0026] like Figure 1-6The high-strength, deformation-resistant automotive crossbeam shown includes a bent longitudinal beam plate 1. The upper and lower edges of the longitudinal beam plate 1 are both equipped with crossbeam plates 2. The main body of the longitudinal beam plate 1 is a long longitudinal plate 101. Both ends of the long longitudinal plate 101 are connected to short longitudinal plates 103 via inclined longitudinal plates 102. The two short longitudinal plates 103 are in the same plane and parallel to the long longitudinal plate 101. Positioning holes 104 are formed within the short longitudinal plates 103. The main body of the crossbeam plate 2 is a long crossbeam 201. The two ends of the long horizontal plate 201 are connected to short horizontal plates 204 by oblique horizontal plates 203. The two short horizontal plates 204, the two oblique horizontal plates 203 and the long horizontal plate 201 are in the same plane. It should be noted that the edge of the long horizontal plate 201 is connected to the edge of the long vertical plate 101, the edge of the oblique horizontal plate 203 is connected to the edge of the oblique vertical plate 102, and the edge of the short horizontal plate 204 is connected to the edge of the short vertical plate 103. Therefore, the orientation of the horizontal beam plate 2 and the vertical beam plate 1 is similar.
[0027] At least one crossbeam plate 2 has a bridging plate 5 fixedly connected between two inclined cross plates 203. The bridging plate 5 is generally connected to the lower crossbeam plate 2. A rib plate 6 is fixedly connected between the two crossbeam plates 2. The side of the rib plate 6 facing away from the longitudinal beam plate 1 is a concave arc shape, and the side of the rib plate 6 facing the longitudinal beam plate 1 is fixedly connected to the longitudinal beam plate 1. It should be noted that there are several rib plates 6 between the long longitudinal plate 101 and the two long cross plates 201, at least two rib plates 6 between the inclined longitudinal plate 102 and the two connected inclined cross plates 203, and at least two rib plates 6 between the short longitudinal plate 103 and the two connected short cross plates 204. The rib plates 6 can effectively maintain the stability between the two crossbeam plates 2 and the longitudinal beam plate 1.
[0028] The longitudinal beam plate 1 has positioning holes 104 at both ends to provide pre-positioning before installation and improve assembly accuracy. The transverse beam plate 2 has several longitudinal connecting holes 202 for vertical connecting parts to pass through. The longitudinal beam plate 1 has a first mounting plate 3 at both ends, and the first mounting plate 3 has a vertical connecting hole 301 for connecting parts in the left and right directions to pass through. The transverse beam plate 2 has a second mounting plate 4 at both ends, and the second mounting plate 4 has a horizontal connecting hole 401 for connecting parts in the front and back directions to pass through.
[0029] Working principle: During installation, the vehicle crossbeam is fixedly connected to other frame structures using connectors that pass through longitudinal connection holes 202, vertical connection holes 301, and horizontal connection holes 401. Because the longitudinal beam plate 1 has a large longitudinal width, the crossbeam plate 2 constrained by the longitudinal beam plate 1 is not prone to bending in the vertical direction. Because the crossbeam plate 2 has a large lateral width, the longitudinal beam plate 1 constrained by the crossbeam plate 2 is not prone to bending in the front-back direction. At the same time, the rib plate 6 located between the crossbeam plate 2 and the longitudinal beam plate 1 can also effectively ensure the included angle between the longitudinal beam plate 1 and the crossbeam plate 2, as well as the spacing between the two crossbeam plates 2, so that the entire vehicle crossbeam has higher strength to resist deformation without increasing its own weight.
[0030] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
