[0045] The frame, as the base and main load-bearing component of the vehicle, is the carrier for connecting other assemblies and parts. During use, it not only bears the loads of various devices, but also bears various loads from inside and outside the vehicle, as well as complex impact loads caused by uneven roads. The frame crossbeam 10 is not only used to ensure the torsional rigidity of the frame and bear longitudinal loads, but also supports the main components of the vehicle.

[0046] At present, most vehicles adopt a structure in which a pipe beam is welded with a bracket to form a crossbeam. This type of crossbeam has a heavy overall weight and a large dimensional chain, low precision in the outer width of the frame, and is not easy to install. In addition, the stress distribution of the crossbeam is uneven and the strength is low due to the influence of welding.

[0047] The present application provides a frame crossbeam 10 , which can relatively reduce the overall mass of the frame, improve the frame precision to facilitate the installation of the frame crossbeam 10 and the corresponding frame longitudinal beams, and can improve the strength of the frame crossbeam 10 .

[0048] See also Figure 1 and Figure 2 As shown, the frame crossbeam 10 includes a main board 100 and side panels 200 disposed on both sides of the main board 100 along a first direction F1. The side panels 200 are connected to the main board 100 at a preset angle A, so that a groove structure is defined between the side panels 200 and the main board 100 for carrying and accommodating vehicle accessories such as a control module, a cooling module, and an engine. In some embodiments, the main board 100 is provided with a first mounting hole 110 and a second mounting hole 120. The first mounting hole 110 is used to fix the front spring front bracket of the vehicle, and the second mounting hole 120 is used to fix the wiring harness bracket, control valve bracket, etc. of the vehicle so as to facilitate the installation of vehicle accessories in the groove structure.

[0049] Combined with reference Figure 3 As shown, in some embodiments, the preset angle A satisfies: 115°≤A≤125°, so that the frame crossbeam 10 has the advantages of easy molding and reasonable layout space. And setting the preset angle within the range of 115°-125° facilitates the present application to set the body and the side plate 200 as one-piece molding, that is, in some embodiments, the frame crossbeam 10 of the present application can be formed in one piece, and the limitation of the preset angle A improves the success rate of its one-piece molding, and on the basis of easy molding, makes the layout space reasonable, and is convenient for installing vehicle accessories, and also has the advantages of improving the frame precision and facilitating the installation of the frame crossbeam 10 and the frame longitudinal beam.

[0050] See also Figure 4As shown, the dimension H of the projection of the side plate 200 and the connecting member 300 on the preset plane M along the third direction F3 satisfies: 360mm≤H≤420mm, and the dimension N of the frame beam 10 in the first direction F1 is preferably 926mm, wherein the first direction F1 and the third direction F3 intersect each other. In other words, the height of the frame beam 10 as a whole in the third direction F3 is within 360mm-420mm, and the dimension N of the frame beam 10 as a whole in the first direction F1 is preferably 926mm. It can be understood that the larger H is, the smaller the preset angle A is, the higher the difficulty of molding the frame beam 10 is, and the more sufficient the space for arranging vehicle accessories on the frame beam 10 is; the smaller H is, the larger the preset angle A is, the lower the difficulty of molding the frame beam 10 is, and the more limited the space for arranging vehicle accessories on the frame beam 10 is. By correspondingly adjusting the dimension H of the projection of the side panel 200 and the connecting member 300 along the third direction F3 on the preset plane M, the size of the preset angle A can be adjusted and the size of the groove structure limited between the side panel 200 and the main board 100 for arranging vehicle accessories can be changed, thereby adjusting the difficulty of forming the frame cross beam 10 and the size of the layout space of the frame cross beam 10 for vehicle accessories.

[0051] That is, by reasonably setting the dimension N of the frame crossbeam 10 in the first direction F1, the dimension H of the projection of the side panel 200 and the connecting member 300 on the preset plane M along the third direction F3, and the preset angle A, a groove structure of a reasonable size can be defined, which is convenient for setting up the front spring front bracket, fixed wiring harness bracket and control valve bracket of the vehicle, so that the control cooling module and engine assembly or high-pressure accessory assembly of the vehicle can be reasonably accommodated and installed in the groove structure limited between the side panel 200 and the main board 100.

[0052] like Figure 1 and Figure 2 The side plate 200 includes a plate body portion 210 and a reinforcement portion 220. Figure 1 The transverse reinforcing ribs 221 and the longitudinal reinforcing ribs 222 in the embodiment of the present invention are as follows: Figure 2 The plate body 210 is connected to the main board 100 at a preset angle A, and the reinforcing portion 220 is connected to the plate body 210 to improve the strength of the plate body 210, or to improve the strength of the side plate 200 and even the frame crossbeam 10 as a whole.

[0053] The frame cross beam 10 of the present application is provided with a main board 100 and side panels 200 arranged on both sides of the main board 100. Compared with the structure of the prior art that adopts pipe beams and brackets to be welded, it is possible to reduce the mass of the frame cross beam 10. The limitation of the preset angle facilitates the forming of the frame cross beam 10 and makes the layout of the frame cross beam 10 for vehicle accessories more reasonable. At the same time, the accuracy of the frame cross beam 10 is improved, which is convenient for the installation of the frame cross beam 10. Combined with the provision of the reinforcement part 220, the strength of the frame cross beam 10 of the present application is improved.

[0054] like Figure 1 The frame cross beam 10 includes two side plates 200 arranged on both sides of the main board 100 along the first direction F1, and the two side plates 200 are symmetrically arranged on opposite sides of the main board 100 relative to a preset plane M, wherein the preset plane M is perpendicular to the first direction F1. The two side plates 200 are symmetrically arranged on both sides of the main board 100, which is conducive to improving the force balance of the cross beam, so that the stress of the cross beam is relatively dispersed when the cross beam carries vehicle accessories, thereby improving the strength of the frame cross beam 10 and facilitating the improvement of the service life of the frame cross beam 10.

[0055] In some embodiments, see Figure 1 As shown, the reinforcing portion 220 includes at least two transverse reinforcing ribs 221 and a longitudinal reinforcing rib 222 arranged at intervals along the second direction F2 on the plate body 210, and the longitudinal reinforcing rib 222 is connected between two adjacent transverse reinforcing ribs 221, and the longitudinal reinforcing rib 222 is recessed between the two adjacent transverse reinforcing ribs 221. Among them, the first direction F1 and the second direction F2 intersect each other. It can be understood that the hollowing between the two adjacent transverse reinforcing ribs 221 arranged at intervals in the transverse direction can save materials and reduce the weight of the frame crossbeam 10. The longitudinal reinforcing rib 222 is connected between the two adjacent transverse reinforcing ribs 221, that is, the strength of the frame crossbeam 10 can be improved while reducing the weight of the frame crossbeam 10. The longitudinal reinforcing rib 222 is recessedly arranged between the two adjacent transverse reinforcing ribs 221, and its recessed arrangement relatively reserves a deformation space for the two adjacent transverse reinforcing ribs 221 to deform relative to each other, thereby avoiding stress concentration, thereby further improving the strength of the frame crossbeam 10 and improving the service life of the frame crossbeam 10.

[0056] In some embodiments, Figure 2 As shown, the reinforcement part 220 includes a recessed part 223, and the recessed part 223 is recessed in the side plate 200, so as to strengthen the strength of the side plate 200 and play a role in structural reinforcement. The recessed part 223 includes a recessed bottom plate and a recessed side plate 200 arranged around the recessed bottom plate, and one end of the recessed side plate 200 away from the recessed bottom plate is connected to the plate body 210, so that the strength of the side plate 200 can be strengthened by the arrangement of the recessed bottom plate and the recessed side plate 200.

[0057] See also Figure 1 and Figure 2 As shown, the frame cross member 10 further includes a connector 300 connected to the end of the side plate 200 away from the main plate 100. In some embodiments, the reinforcing portion 220 is connected between the plate body portion 210 and the connector 300, so that the reinforcing portion 220 can improve the structural strength between the plate body and the connector 300, and avoid stress concentration between the plate body and the connector 300, which causes the plate body and the connector 300 to separate from each other. The connector 300 is provided with a plurality of connecting holes 310 along the first direction F1, and the frame cross member 10 can be connected to the frame longitudinal beam through the plurality of connecting holes 310.

[0058] In some embodiments, the connecting member 300 is provided with 14 connecting holes 310, and the plurality of connecting holes 310 are arranged in an array, so as to improve the applicability and versatility of the frame crossbeam 10 of the present application, so that it can be connected to different frame longitudinal beams, that is, suitable for different frame longitudinal beams.

[0059] In some embodiments, Figure 1 and Figure 2 , both sides of the reinforcement part 220 along the second direction F2 are provided with flanged parts 230 extending along the third direction F3, wherein the first direction F1, the second direction F2 and the third direction F3 intersect each other. This can improve the strength of the reinforcement part 220, thereby improving the strength of the frame crossbeam 10. In some embodiments, along the second direction F2, both sides of the main board 100, the plate body 210 and the reinforcement part 220 are provided with flanged parts 230, so as to improve the strength of the main board 100, the plate body 210 and the reinforcement part 220, thereby improving the strength of the frame crossbeam 10. Figure 1 As shown, flange portions 230 are provided on both sides of any transverse reinforcing rib 221 along the second direction F2 to improve the strength of the reinforcing portion 220 .

[0060] Combined with reference Figure 4 As shown, along the second direction F2, the size S3 of the reinforcing portion 220 is greater than the size S2 of the plate body 210, that is, S3>S2. From the plate body 210 to the reinforcing portion 220, the size of the side panel 200 along the second direction F2 gradually increases, or in other words, the side panel 200 is arranged with unequal widths, and the size of the plate body 210 is smaller than the reinforcing portion 220, which can reduce the weight of the frame cross beam 10, and the larger size of the reinforcing portion 220 can ensure the strength of the frame cross beam 10.

[0061] See also Figure 1-4As shown, in some embodiments, the main board 100 includes a middle portion 130 and an extension portion 140, and the dimension L of the middle portion 130 along the first direction F1, the dimension S1 of the middle portion 130 along the second direction F2, and the dimension S2 of the plate body 210 along the second direction F2 satisfy: 20 / 350≤(S2-S1) / L3≤20 / 450. In some embodiments, the first mounting hole 110 is provided in the extension portion 140, and the second mounting hole 120 is provided in the middle portion 130. By setting the dimension S1 of the middle portion 130 along the second direction F2, the dimension S2 of the plate body 210 along the second direction F2, and the dimension L of the middle portion 130 along the first direction F1, the front spring front bracket, the wiring harness bracket, and the control valve bracket of the vehicle can be reasonably arranged, and then the control cooling module and the engine assembly or the high-pressure accessory assembly of the vehicle can be reasonably accommodated and installed in the groove structure limited between the side plate 200 and the main board 100.

[0062] And refer to Figure 5 As shown, Figure 5 It is a display diagram of the rebound displacement when the rebound test is performed on the frame crossbeam 10 of the present application. It can be seen that in the present application, the dimension L of the middle portion 130 along the first direction F1, the dimension S1 of the middle portion 130 along the second direction F2 and the dimension S2 of the plate body 210 along the second direction F2 satisfy: 20 / 350≤(S2-S1) / L3≤20 / 450, the dimension H of the projection of the side plate 200 and the connecting member 300 on the preset plane M along the third direction F3 satisfies: 360mm≤H≤420mm, the dimension N of the frame beam 10 in the first direction F1 is preferably 926mm, and the dimension N of the frame beam 10 as a whole in the first direction F1 is preferably 926mm. On this basis, the two side plates 200 of the frame beam 10 of the present application have better rebound displacement, and the farther away from the main board 100, the greater the rebound displacement, which can reach a rebound displacement of 21.350mm, and the elasticity is better, which can play a buffering role to avoid excessive rigidity and cause the frame beam 10 to be easy to break.

[0063] In some embodiments, the frame beam 10 of the present application is manufactured through an integrated molding process, and is sequentially processed through processes such as blanking and punching, flanging forming, bending, flanging again, and oblique wedge punching, wherein the blanking and punching complete the integrated molding of the frame beam 10, and form a reinforcement portion 220, and penetrate the first mounting hole 110 and the second mounting hole 120, the flanging forming is used to flanging the side panel 200 on both sides along the second direction F2, the bending is to bend the blanking so that a preset angle A is formed between the main panel 100 and the side panel 200, the flanging again is used to flanging the main panel 100 on both sides along the second direction F2, the oblique wedge punching is to punch the connecting member 300, and penetrate the connecting hole 310, and in some embodiments, the second mounting hole 120 can be penetrated and completed in the oblique wedge punching step.

[0064] In some embodiments, the dimensional error of the frame beam 10 of the present application along the second direction F2 does not exceed 0.5 mm, and the dimensional error along the third direction F3 does not exceed 0.22 mm. The parallelism of the planes relative to the connecting member 300 and the side panel 200 relative to the third direction F3 is 0.5.

[0065] The present application also provides a vehicle, including the above-mentioned frame crossbeam 10, and also including a frame longitudinal beam, wherein the frame crossbeam 10 is connected to the frame longitudinal beam through a connecting member 300. The frame crossbeam 10 of the present application is provided with side panels 200 on both sides of the main board 100, and the plate body 210 of the plate body of the side panel 200 is connected to the main board 100 at a preset angle A to improve the assembly accuracy of the frame crossbeam 10, and at the same time, a reinforcement portion 220 is provided on the plate body 210, and the reinforcement portion 220 is used to improve the strength of the frame crossbeam 10, which has the advantages of light overall weight, high frame accuracy and high strength.

[0066] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
