[0026] (1) After demolding, the two side beams are fixedly connected to the main body on one side, and are connected to each other through the connecting beam on the other side, so that the connecting beam, the two side beams and the main body form a closed loop, and a stress point is added to each side beam, so that the relative positions of the two side beams can be limited by the connecting beam during the subsequent cooling process after demolding, and the connection angle between the single side beam and the main body during the cooling process can be prevented from deviating.

[0044] In order for those skilled in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings.

[0045] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0046] Vehicles are widely used in daily life, and a vehicle usually includes a bearing seat and a vehicle body, and the vehicle body is installed on the bearing seat.

[0047] The bearing seat includes a front vehicle part, a middle part and a rear vehicle part, the front vehicle part is used for mounting a front vehicle anti-collision beam and elements such as air conditioners of the front vehicle; the middle part is the bottom main body of the vehicle, used for mounting structures such as batteries, referred to as a base here; the rear vehicle part is used for connecting the trunk or container-like structure at the tail of the vehicle, referred to as a vehicle body here. The vehicle body is installed above the bearing seat, and a space for driving and riding is formed between the bearing seat and the vehicle body.

[0048] In order to facilitate the production and processing of the bearing seat, the bearing seat can adopt a die casting production process. Unlike traditional vehicle die castings, the bearing seat integrates dozens or even hundreds of vehicle body structural parts, so there are higher requirements for the overall die casting quality, mechanical properties and dimensions to facilitate subsequent processing. Among them, the vehicle body is also located in the bearing seat and is die cast together with other parts in the bearing seat.

[0049] According to the solidification theory of aluminum alloy, the larger the local volume of the aluminum alloy casting is, the more obvious the volume shrinkage range is. After the die casting body is demolded, the internal solidification is not complete, and there is still a cooling time, and the shape and size change due to internal stress still occurs.

[0050] Please refer to Figure 1 , the current vehicle body includes a main body 1 and two side beams 2, the side beams 2 longitudinally extend through the whole vehicle, and the length is relatively long. During die casting, the side beams 2 will produce more obvious internal stress shrinkage phenomenon during cooling due to the large volume at the connection between the side beams 2 and the main body 1, which causes the angle deviation between the side beams 2 and the main body 1 to exceed the expected value.

[0051] Please refer to Figure 2 , based on this, the application provides a new vehicle body, which includes a main body 1, two side beams 2 and a connecting beam 3.

[0052] The two side beams 2 are arranged on the main body 1 in a spaced manner, and each side beam 2 extends away from the main body 1.

[0053] The connecting beam 3 is arranged between the two side beams 2, and the two ends of the connecting beam 3 are connected with the two side beams 2 respectively.

[0054] After demolding, the two side beams 2 are arranged on the main body 1 and fixedly connected with the main body 1, and the two side beams 2 are also connected through the connecting beam 3, so that the connecting beam 3, the two side beams 2 and the main body 1 form a closed loop.

[0055] In this scheme, the main body 1 and the connecting beam 3 are arranged in a spaced manner along the extension direction of each side beam 2, so that the side beam 2 has two mechanical connection points. Compared with the prior art, one stress point is added at the free end of each side beam 2, so that in the subsequent cooling process after demolding, the relative positions of the two side beams 2 can be further limited by the connecting beam 3, and the connection angle between the side beam 2 and the main body 1 is prevented from deviating due to the internal stress generated by the internal cooling at the connection between the side beam 2 and the main body.

[0056] In the above scheme, the vehicle body is a casting, so the main body 1, the side beam 2 and the connecting beam 3 should be made by integral molding. In integral molding, the side beam 2 and the connecting beam 3 adopt surface contact, and the side beam 2 and the main body 1 also adopt surface contact. This kind of contact mode can not only make the connection strength between the side beam 2 and the main body 1 high and meet the use standard, but also make the connection between the side beam 2 and the connecting beam 3 stable, so that the position of the side beam 2 is more determined.

[0057] In some examples, the connecting beam 3 can be a process beam, that is, in the die casting process, the mold space of the area where the connecting beam 3 is arranged is provided in the mold, so that it is shaped when casting; in the subsequent processing process, the connecting beam 3 can be used as a process support beam or a positioning beam, and assist the cooling of the side beam 2 and other processing and molding processes of the side beam 2, and after the side beam 2 is cooled and molded or the subsequent process is basically shaped, the process beam (that is, the connecting beam 3) can be removed. Since the connecting beam 3 and the side beam 2 are integrally cast, the connecting beam 3 can be removed by cutting.

[0058] In this way, the vehicle body processed has shape precision and strength that meet the design expectations and meet the use requirements of the vehicle.

[0059] For example, the connecting beam 3 can be a cylindrical beam, a square beam, an L-shaped beam, or an I-shaped beam, which can all meet the purpose of maintaining the positions of the two side beams 2 through the connecting beam 3.

[0060] For example, the cross-sectional area of the connecting beam 3 can be close to the cross-sectional area of the side beam 2. Here, close can be understood as equal to the cross-sectional area of the connecting beam 3, or the cross-sectional area of the connecting beam 3 is smaller than the cross-sectional area of the side beam 2 under the premise of ensuring the strength of the connecting beam 3. Here, the cross-sectional area can be understood as the area, or the thickness or the length in a certain direction.

[0061] For example, the diameter of the connecting beam 3 can be uniform or non-uniform.

[0062] When the connecting beam 3 is a process beam, the cut connecting beam 3 can be recast and used for the casting process of the vehicle body.

[0063] In other examples, the connecting beam 3 can also be part of the vehicle body. After the side beam 2 is processed through the connecting beam 3, the connecting beam 3 can also be processed in some way, so that the connecting beam 3 can be applied to the positioning of the front end module or the rear end module of the subsequent vehicle body, or holes can be drilled in the connecting beam 3 and a radiator or other structure can be installed through the connecting beam 3, which can make the connecting beam 3 directly applied to the vehicle.

[0064] Please refer to Figure 3 On this basis, the vehicle body further comprises an extension plate 4, the extension plate 4 is attached to the connecting beam 3, and the two ends of the extension plate 4 are respectively connected to the two side beams 2.

[0065] The extension plate 4 is attached to the connecting beam 3, which can further improve the strength of the connecting beam 3, so that the connecting beam 3 has better connection and fixing effect on the two side beams 2.

[0066] In this scheme, the extension plate 4 is also attached to the connecting beam 3, which can increase the thickness of the connecting beam 3 in a certain direction through the extension plate 4 to improve the bending resistance of the connecting beam 3.

[0067] In some examples, the extension plate 4 can be a flat plate, the connecting beam 3 can be a strip structure, the extension plate 4 is attached to one end surface of the connecting beam 3, and extends in the same direction as the connecting beam 3, so that the structure formed by the connecting beam 3 and the extension plate 4 has a T-shaped or T-like cross section.

[0068] In other examples, when the extension plate 4 is a flat plate, the connecting beam 3 and the extension plate 4 can also form an L-shaped structure, which can also have similar effects.

[0069] In other examples, the extension plate 4 can be a curved plate, and the extension plate 4 extends around the surface of the connecting beam 3 to form a spring-shaped structure.

[0070] In other examples, the connecting beam 3 can also be a cylindrical beam or a prismatic beam, and the extension plate 4 is arranged on the surface of the connecting beam 3 to improve the strength of the connecting beam 3.

[0071] In other examples, the connecting beam 3 can also be a chain structure, that is, a plurality of through holes are arranged on the connecting beam 3, and the extension plate 4 is arranged on one side of the connecting beam 3 or on the surface of the connecting beam 3 to ensure the strength of the connecting beam 3 while reducing the material consumption of the connecting beam 3.

[0072] Please refer to Figure 4 On this basis, the number of extension plates 4 is two, and the two extension plates 4 are arranged on opposite sides of the connecting beam 3.

[0073] When the two extension plates 4 are arranged in the above manner, the extension plate 4 and the connecting plate can form an I-shaped cross section, further improving the strength of the connecting beam 3 and the effect of the connecting beam 3 on fixing the two side beams 2.

[0074] The I-shaped steel has good rigidity and strength, and can be used for connection between the two side beams 2.

[0075] In some examples, the extension plate 4 can be two, and the two extension plates 4 can be equal in size and arranged symmetrically about the connecting beam 3.

[0076] In other examples, the two extension plates 4 can form an included angle, and the two extension plates 4 can be fixedly connected to each other while being fixedly connected to the connecting beam 3.

[0077] In other examples, the number of extension plates 4 can not be limited to two, and can be set to three, four or five to further improve the strength of the connecting beam 3.

[0078] Please refer to Figure 5On this basis, the vehicle body further comprises a plurality of reinforcing ribs 5, which are arranged at intervals between the two extension plates 4 and are connected with the connecting beam 3, and the two ends of the reinforcing ribs 5 are connected with the two extension plates 4 respectively.

[0079] The reinforcing ribs 5 are connected with the two extension plates 4 and the connecting beam 3 at the same time, which not only can improve the bonding strength between the connecting beam 3 and the extension plates 4 and the bonding strength between the two extension plates 4, but also can further improve the shear resistance of the connecting beam 3.

[0080] In some examples, the setting direction of the reinforcing ribs 5 can be opposite to the extension direction of the connecting beam 3, that is, the extension direction of the reinforcing ribs 5 is perpendicular to the surface of the extension plates 4, so that the reinforcing ribs 5 can provide the maximum strength enhancement effect for the extension plates 4.

[0081] In some examples, the diameter of the reinforcing ribs 5 can be similar to the thickness of the connecting beam 3, so that the strength of the reinforcing ribs 5 can be close to the strength of the extension plates 4, avoiding unnecessary waste of strength.

[0082] In some examples, the reinforcing ribs 5 are arranged in multiple, and the multiple reinforcing ribs 5 are arranged between the two extension plates 4 along the extension direction of the connecting beam 3.

[0083] In other examples, when the reinforcing ribs 5 are arranged in multiple, the multiple reinforcing ribs 5 can also intersect with each other, which can also have the effect of strengthening the strength of the extension plates 4 and the connecting beam 3.

[0084] Please continue to refer to Figure 5 On this basis, the two extension plates 4 are located on the side of the connecting beam 3 close to the main body 1 and the side of the connecting beam 3 away from the main body 1 respectively, and the height of the extension plate 4 located on the side of the connecting beam 3 away from the main body 1 is greater than that of the extension plate 4 located on the side of the connecting beam 3 close to the main body 1.

[0085] The extension plate 4 located on the side away from the main body 1 is located on the outermost side of the edge beam 2, and when the edge beam 2 deforms, the extension plate 4 on the outermost side can have the most direct shape maintaining effect on the edge beam 2, and at this time, setting the extension plate 4 on the side away from the main body 1 as a higher extension plate 4 can make the connecting beam 3 and the extension plate 4 have a better fixing effect on the edge beam 2.

[0086] In some examples, the height of the extension plate 4 on the side away from the main body 1 can be 1.2-2 times the height of the extension plate 4 on the side close to the main body 1, and the thickness of the two extension plates 4 can be the same or the thickness of the former can be greater than that of the latter, so as to provide higher connecting strength.

[0087] In some examples, the purpose of setting the height of the extension plate 4 on the side away from the main body 1 larger is to make it have higher strength, so that a rib protrusion can be arranged on the extension plate 4 to improve its strength.

[0088] In other examples, the extension plate 4 can also be reinforced in strength after demolding, and similar effects can also be achieved.

[0089] Please refer to Figure 5 On this basis, the connecting beam 3 is arranged at the end of the edge beam 2 away from the main body 1. When the angle between the edge beam 2 and the main body 1 deviates, the length of the edge beam 2 will make the displacement of the edge beam 2 away from the main body 1 larger. By arranging the connecting beam 3 at the end of the edge beam 2 as described above, compared with arranging the connecting beam 3 at the middle of the edge beam 2 or near the main body 1, the relative position between the two edge beams 2 can be fixed more firmly, and at the same time, the connecting beam 3 can be located at the farthest place of the pouring flow during pouring, avoiding affecting the pouring quality of the original main body 1 and edge beam 2.

[0090] In some examples, the shape of the edge beam 2 is not a regular shape. In order to make the installation position of the edge beam 2 meet the strength requirements of the vehicle, the cross-sectional area of the edge beam 2 gradually decreases from the main body 1 to the connecting beam 3, so the cross-sectional area of the end of the edge beam 2 away from the main body 1 is smaller.

[0091] At the same time, when the edge beam 2 is installed, other components need to be installed at the end of the edge beam 2, so the position of the to-be-installed component needs to be processed during processing. At this time, the installation position of the connecting beam 3 should be set to avoid the position, so that a certain distance is left between the connecting beam 3 and the end of the edge beam 2 away from the main body 1.

[0092] In some examples, the edge beam 2 has a through hole during casting, and the connecting beam 3 should also avoid the position of the through hole during design, so that the connecting beam 3 can be connected more stably with the edge beam 2, and at the same time, the position of the connecting beam 3 avoids affecting the subsequent processing process of the through hole on the edge beam 2.

[0093] In other examples, the edge beam 2 can be arranged on the end face of the edge beam 2 away from the main body 1, and the connection relationship between the two edge beams 2 and the connecting beam 3 is the same, and the position of the edge beam 2 is fixed by the fixing of the two end face supports of the edge beam 2 by the connecting beam 3 and the main body 1.

[0094] In this example, since the connecting beam 3 is arranged outside the edge beam 2, the connecting beam 3 can be cut off in the subsequent process, and then the edge of the edge beam 2 is processed, and similar effects can also be achieved, so that the connection angle between the edge beam 2 and the main body 1 and the overall shape meet the expected design and use requirements.

[0095] On this basis, the connecting beam 3 is arranged in multiple, and the multiple connecting beams 3 are distributed at intervals. The multiple connecting beams 3 distributed at intervals can further improve the relative position between the two edge beams 2, and make the fixing effect of the edge beam 2 better.

[0096] In some examples, the plurality of connecting beams 3 can be arranged along the extension direction of the edge beams 2, or arranged along other directions, so as to increase the stress points on each edge beam 2 and make the shape and position of the edge beams 2 more stable.

[0097] In some examples, the number of connecting beams 3 can be set to 2, 3 or 4, so as to further improve the holding effect of the edge beams 2.

[0098] In the above examples, when the connecting beams 3 are arranged in multiple, the cross-sectional area of each connecting beam 3 can be reduced, so as to cool the connecting beams 3 more quickly, avoid the internal stress deformation of the connecting beams 3 after demolding due to internal cooling, and cause the deformation of the edge beams 2 and the main body 1 which have not been completely cooled.

[0099] In other examples, the plurality of connecting beams 3 can also be connected by connecting rods, so as to facilitate the flow of the casting material in the mold cavity.

[0100] In other examples, the connecting beams 3 can be partially hollow, so as to reduce the material consumption of the connecting beams 3; at the same time, the hollow connecting beams 3 can also have good rigidity, so as to have high connection strength between the connecting beams 3 and the edge beams 2.

[0101] Please refer to Figure 5 On this basis, the vehicle body further comprises a pouring body 6, which is arranged in the space surrounded by the connecting beams 3, the main body 1 and the two edge beams 2, and the pouring body 6 comprises a material cake 61 and a plurality of connecting bodies 62, one end of the plurality of connecting bodies 62 is connected with the material cake 61, and the other end of the plurality of connecting bodies 62 is connected with the edge beams 2 or the main body 1. The pouring body 6 is a pouring structure formed in the die casting process, and is formed through the sprue and the material cake 61, so as to assist the connecting beams 3 in demolding and play a certain shaping effect on the two edge beams 2.

[0102] The pouring body 6 is a product formed by pouring of the pouring system of the mold.

[0103] In some examples, the connecting bodies 62 can be cylindrical or have other shapes.

[0104] In some examples, since the pouring system usually comprises a straight sprue and a horizontal sprue, the shape of the connecting bodies 62 should correspond to the above-mentioned sprues.

[0105] In some examples, in order to make the size and strength of the cast material better, the pouring material is filled at the gate when pouring, and a certain pressure is provided for the internal pouring cavity, and the pouring material at the gate forms a cake structure after cooling, which is called a cake 61. The volume of the cake 61 is usually large, so the cooling speed of the cake 61 is relatively slow, and the cake 61 is not completely cooled during demolding, and shrinks during the subsequent cooling process and generates a pulling force on the connecting body 62. These local pulling forces can also have a certain effect on the shaping of the side beam 2 and the main body 1.

[0106] Please refer to Figure 5 On this basis, at least one connecting body 62 is connected to the side beam 2, and at least one connecting body 62 is connected to the main body 1. In order to make the pouring quality of the main body 1 and the side beam 2 better, the main body 1 and the side beam 2 should be provided with a gate so that the pouring material can be injected into the cavity where the main body 1 and the side beam 2 are located along the gate, and the main body 1 and the side beam 2 with better pouring quality are formed.

[0107] In some examples, the connecting body 62 is located at the gate in the mold, so in order to ensure the pouring quality of the main body 1 and the side beam 2, the main body 1 and the side beam 2 should be directly connected to at least one pouring channel to ensure the pouring quality of the main body 1 and the side beam 2.

[0108] In some examples, when the connecting beam 3 is only used as a process beam, the connecting beam 3 does not need to be connected to the connecting body 62, that is, the connecting beam 3 can be located at the farthest position of the pouring material flow, and at this time the casting quality of the connecting beam 3 is relatively poor compared with the side beam 2 and the main body 1, but it can still play a corresponding role in maintaining the position of the side beam 2.

[0109] In this example, when the connecting beam 3 is injected with pouring material through the area where the side beam 2 is located, the original pouring system does not need to be modified, and the pouring quality of the connecting beam 3 does not need to be considered, which can reduce the manufacturing cost of the connecting beam 3.

[0110] In other examples, when the connecting beam 3 is part of the vehicle, the connecting beam 3 itself should have good casting quality to improve its use strength and service life, and the connecting beam 3 should also be connected to the connecting body 62 at this time, so that the shape and quality of the connecting beam 3 can meet the design and use requirements, and improve the quality of the connecting beam 3.

[0111] According to another aspect of the present application, a vehicle is provided.

[0112] The vehicle includes a base, a vehicle body and a vehicle body, the vehicle body is arranged on the base and connected with the base; the vehicle body is connected with the base and arranged on the side of the base away from the head of the vehicle, and the vehicle body is connected with the vehicle body. The shape of the vehicle main body 1 of the vehicle adopts the vehicle body, which is more in line with the expected setting and use requirements.

[0113] In some examples, when the connecting beam 3 is a process beam, both the connecting beam 3 and the casting body 6 should be cut off in the subsequent processing process so that the final vehicle body meets the design and use requirements.

[0114] In this example, the final structure required by the vehicle body only includes two side beams 2 and the main body 1, and the main body 1 is fixedly connected with the base in a manner of integral casting; the vehicle body and the base are fixedly connected in a manner of welding.

[0115] In some other examples, the connecting beam 3 can also be a structural member of the vehicle, and in this case, the vehicle body only needs to cut off the casting body 6 formed by casting.

[0116] In some examples, the vehicle body with the added connecting beam 3 has higher precision after casting demolding, higher product yield, lower subsequent processing difficulty and better product quality, is easier to assemble with the vehicle body, and the produced vehicle has better anti-impact performance at the vehicle body.

[0117] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any change or replacement within the technical scope disclosed in the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
