Description

Technical Field

[0001] This application relates to the technical field of automobiles, in particular to a vehicle frame and a vehicle. Background Art

[0002] The girder is one of the important components of an automobile frame, having sufficient strength and stiffness to bear the load of the automobile and the impact transmitted from the wheels. In the prior art, the girder includes a front girder, a front middle girder, and a rear middle girder. Different plate thicknesses and materials are used for each section of the girder. Among them, a support plate is connected to the outside of the front middle girder, and adjacent girders, as well as between the front middle girder and the support plate, are fixedly connected by welding, resulting in poor integrity of the girder. During the assembly process, a large number of components and welding points are required, leading to poor overall strength and stiffness of the girder. Summary of the Utility Model

[0003] In view of this, this application provides a vehicle frame and a vehicle to solve the technical problem of poor integrity of the girder of the vehicle frame in the prior art.

[0004] This application provides a vehicle frame, which includes a front girder, a middle girder, and a connecting beam. The front girder is connected to a front anti-collision beam, the middle girder is connected to an inner sill panel, and the front girder and the middle girder are connected by the connecting beam. Among them, the connecting beam includes a body part and a support part, and the body part is connected to the inner sill panel through the support part, and the body part and the support part are of an integrally formed structure.

[0005] In the embodiments of this application, the front girder, the connecting beam, and the middle girder are sequentially connected along the first direction x, and the front girder and the middle girder are respectively connected to the front anti-collision beam and the inner sill panel, so that when the vehicle frame bears an external force (for example, when the front anti-collision beam bears an external force), the external force can be transmitted from the front girder to the connecting beam, then from the connecting beam to the middle girder, and then the middle girder transmits the external force to the inner sill panel and the rear girder of the vehicle frame respectively, thereby realizing the transmission and dispersion of the external force. At least part of the connecting beam can also be connected to the inner sill panel, so that the connecting beam can simultaneously transmit the external force to the inner sill panel and the middle girder respectively, thereby realizing further dispersion of the external force, which is beneficial to reducing the possibility of deformation of the components bearing the external force and the components transmitting the external force, improving the structural strength and structural stability of the vehicle body, and further enabling the vehicle to bear greater external forces and improving the safety of the passenger compartment.

[0006] Specifically, the connecting beam includes a main body portion and a supporting portion. The two ends of the main body portion along the first direction x of the vehicle frame are respectively connected to the front main beam and the middle main beam. The supporting portion is located on one side of the main body portion facing the inner panel of the door sill along the second direction y of the vehicle frame. The main body portion is connected to the inner panel of the door sill through the supporting portion, so that when an external force is transmitted from the front main beam to the connecting beam, it can be transmitted to the middle main beam and the inner panel of the door sill through the main body portion and the supporting portion respectively. Therefore, through the connecting beam, the vehicle frame can have multiple routes for transmitting external forces to play a role in dispersing external forces.

[0007] More specifically, the main body portion and the supporting portion are of an integrally formed structure, which is beneficial to improving the integrity of the connecting beam and the transmission effect of external forces, so as to better transmit external forces to the middle main beam and the inner panel of the door sill, thereby reducing the possibility of deformation of the connecting beam during the transmission of external forces and improving the structural stability of the connecting beam. At the same time, the integrally formed manner of the main body portion and the supporting portion reduces the connection relationship between the two, thereby reducing the number of used parts and the number of welding points, reducing the accumulated errors during the welding process, reducing the errors of the dimensional chain, and further being beneficial to improving the quality of the connecting beam and reducing the production cost of the vehicle frame. In addition, the integrally formed manner can also reduce the assembly steps between the main body portion and the supporting portion, which is beneficial to improving the production efficiency of the vehicle frame.

[0008] In a possible implementation manner, the front main beam has a first groove, the middle main beam has a second groove, the main body portion has a third groove, the first groove communicates with the third groove, and the second groove communicates with the third groove.

[0009] In a possible implementation manner, along the first direction x, the projection of the front main beam coincides with the projection of the middle main beam.

[0010] In a possible implementation manner, along the second direction y, there is a spacing L1 between the front main beam and the middle main beam, and 80mm ≤ L1 ≤ 160mm is satisfied, and / or, along the third direction z, there is a spacing L2 between the front main beam and the middle main beam, and 100mm ≤ L2 ≤ 200mm is satisfied.

[0011] In a possible implementation manner, the vehicle frame further includes a reinforcing plate, and the reinforcing plate is installed in the third groove and fits with at least part of the inner wall of the third groove to form a cavity.

[0012] In a possible implementation manner, along the second direction y, the reinforcing plate is spaced from the supporting portion.

[0013] In a possible implementation, the reinforcing plate includes a main body portion, a first extension portion and a second extension portion connected to the main body portion. The main body portion is installed in the third groove. Along the first direction x, the first extension portion extends from the main body portion into the first groove, and the second extension portion extends from the main body portion into the second groove.

[0014] In a possible implementation, the reinforcing plate further includes reinforcing ribs, which protrude relative to the bottom of the reinforcing plate and extend along the first direction x.

[0015] In a possible implementation, there are multiple reinforcing ribs, and the multiple reinforcing ribs are spaced along the first direction x. The reinforcing ribs are one or more of straight and curved types.

[0016] This embodiment also provides a vehicle, including a chassis and a vehicle frame. The vehicle frame is the vehicle frame described in any one of the above. Wherein, the chassis includes a swing arm, and during the assembly of the vehicle, the swing arm is cooperatively connected with the connecting beam.

[0017] In the embodiments of the present application, by adopting the above vehicle frame, the overall structural strength and stiffness of the vehicle can be improved, the number of components and the number of welding points used during vehicle assembly are reduced, the cumulative error of welding is eliminated, and the dimensional chain error is reduced, thereby improving the overall vehicle quality while reducing production costs. At the same time, the connecting beam of the vehicle frame can also integrate the function of installing the chassis, so that the swing arm of the chassis is installed on the connecting beam of the vehicle frame. Specifically, the installation point of the swing arm can be located between the reinforcing plate and the supporting portion, so that during the driving of the vehicle, the external force borne by the swing arm can also be transmitted and dispersed through the connecting beam 3, thereby improving the driving stability of the vehicle and the comfort of passengers.

[0040] For a better understanding of the technical solutions of this application, the embodiments of this application will be described in detail below with reference to the drawings.

[0041] It should be clear that the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts belong to the scope protected by this application.

The singular forms "a", "the", and "said" used in the embodiments of the present application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0043] It should be understood that the term " / and" used herein is only a relational term describing associated objects, indicating that three relationships may exist. For example, A / and B may represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally indicates that the associated objects before and after are in an "or" relationship.

[0044] The embodiments of the present application provide a vehicle frame, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown. The vehicle frame includes a front main beam 1, a middle main beam 2, and a connecting beam 3. The connecting beam 3 is located between the front main beam 1 and the middle main beam 2. The front main beam 1 is used to connect with the front anti-collision beam, the middle main beam 2 is used to connect with the inner panel of the sill, and the connecting beam 3 is used to connect the front main beam 1 and the middle main beam 2.

[0045] It should be noted that in the present application, the length direction of the vehicle frame is defined as the first direction x, the width direction of the vehicle frame is defined as the second direction y, and the height direction of the vehicle frame is defined as the third direction z.

[0046] In the embodiments of the present application, the front main beam 1, the connecting beam 3, and the middle main beam 2 are connected in sequence along the first direction x, and the front main beam 1 and the middle main beam 2 are respectively connected to the front anti-collision beam and the inner panel of the sill, so that when the vehicle frame bears an external force (for example, when the front anti-collision beam bears an external force), the external force can be transmitted from the front main beam 1 to the connecting beam 3, then from the connecting beam 3 to the middle main beam 2, and then the middle main beam 2 transmits the external force to the inner panel of the sill and the rear main beam of the vehicle frame respectively, thereby realizing the transmission and dispersion of the external force.

[0047] Among them, at least a part of the connecting beam 3 can also be connected to the inner panel of the sill, so that the connecting beam 3 can simultaneously transmit the external force to the inner panel of the sill and the middle main beam 2 respectively, thereby realizing the further dispersion of the external force, which is beneficial to reducing the possibility of deformation of the components bearing the external force and the components transmitting the external force, improving the structural strength and structural stability of the vehicle body, and further enabling the vehicle to bear a greater external force and improving the safety of the passenger compartment.

[0048] Specifically, the connecting beam 3 includes a body portion 32 and a supporting portion 33. The two ends of the body portion 32 along the first direction x of the vehicle frame are respectively connected to the front main beam 1 and the middle main beam 2. The supporting portion 33 is located on one side of the body portion 32 facing the inner door sill panel along the second direction y of the vehicle frame. The body portion 32 is connected to the inner door sill panel through the supporting portion 33, so that when an external force is transmitted from the front main beam 1 to the connecting beam 3, it can be transmitted to the middle main beam 2 and the inner door sill panel respectively through the body portion 32 and the supporting portion 33. Therefore, through the connecting beam 3, the vehicle frame can have multiple routes for transmitting external forces to play a role in dispersing external forces.

[0049] More specifically, the body portion 32 and the supporting portion 33 are of an integrally formed structure, which is beneficial to improving the integrity of the connecting beam 3 and the transmission effect of external forces, so as to better transmit the external forces to the middle main beam 2 and the inner door sill panel, thereby reducing the possibility of deformation of the connecting beam 3 during the transmission of external forces and improving the structural stability of the connecting beam 3. At the same time, the integrally formed manner of the body portion 32 and the supporting portion 33 reduces the connection relationship between the two, thereby reducing the number of used parts and the number of welding points, reducing the accumulated errors during the welding process, reducing the errors of the dimension chain, and further being beneficial to improving the quality of the connecting beam 3 and reducing the production cost of the vehicle frame. In addition, the integrally formed manner can also reduce the assembly steps between the body portion 32 and the supporting portion 33, which is beneficial to improving the production efficiency of the vehicle frame.

[0050] It should be noted that the front main beam 1 and the connecting beam 3, the middle main beam 2 and the connecting beam 3, between the middle main beam 2 and the inner door sill panel, and between the connecting beam 3 and the inner door sill panel are all connected by welding.

[0051] In a specific embodiment, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the front main beam 1 has a first groove 11, the middle main beam 2 has a second groove 21, and the body portion 32 has a third groove 31. The first groove 11 is communicated with the third groove 31, and the second groove 21 is communicated with the third groove 31.

[0052] In the embodiment of the present application, the connecting beam 3 is used to connect the front main beam 1 and the middle main beam 2. Among them, one end of the front main beam 1 along the first direction x facing the connecting beam 3 extends into the inside of the connecting beam 3 and is welded to the connecting beam 3. One end of the middle main beam 2 along the first direction x facing the connecting beam 3 extends into the inside of the connecting beam 3 and is welded to the connecting beam 3, so that the first groove 11, the second groove 21 and the third groove 31 are communicated with each other, which is beneficial to improving the transmission effect of external forces along the first direction x, reducing the possibility of damage to the connection between the front main beam 1 and the connecting beam 3 and the connection between the connecting beam 3 and the middle main beam 2 caused by the obstruction of external forces during the transmission process, thereby improving the stability and reliability of the connection among the three, and further improving the overall structural strength of the vehicle frame.

[0053] In a specific embodiment, along the first direction x, the projection of the front main beam 1 coincides with the projection of the middle main beam 2.

[0054] In the embodiment of the present application, when the projection of the front main beam 1 coincides with the projection of the middle main beam 2 along the first direction x, the two can extend along the same straight line, and the front main beam 1 and the middle main beam 2 are connected by a connecting beam 3, so that the whole after the three are connected is approximately a longitudinal beam extending along the first direction x. When the vehicle frame bears an external force, the absorption effect, transmission effect and dispersion effect of the external force by the front main beam 1, the middle main beam 2 and the connecting beam 3 can be improved, and the possibility of deformation of the three is reduced, thereby improving the overall structural strength of the vehicle frame and further improving the safety of the occupant compartment.

[0055] In a specific embodiment, as Figure 3 and Figure 4 shown, along the second direction y, there is a spacing L1 between the front main beam 1 and the middle main beam 2, and L1 satisfies 80 mm ≤ L1 ≤ 160 mm, and / or, along the third direction z, there is a spacing L2 between the front main beam 1 and the middle main beam 2, and L2 satisfies 100 mm ≤ L2 ≤ 200 mm.

[0056] Among them, the spacing L1 between the front main beam 1 and the middle main beam 2 can specifically be 80 mm, 85 mm, 90 mm, 95 mm, 100 mm, 105 mm, 110 mm, 115 mm, 120 mm, 125 mm, 130 mm, 135 mm, 140 mm, 145 mm, 150 mm, 155 mm, 160 mm, etc.

[0057] The spacing L2 between the front main beam 1 and the middle main beam 2 can specifically be 100 mm, 105 mm, 110 mm, 115 mm, 120 mm, 125 mm, 130 mm, 135 mm, 140 mm, 145 mm, 150 mm, 155 mm, 160 mm, 165 mm, 170 mm, 175 mm, 180 mm, 185 mm, 190 mm, 195 mm, 200 mm, etc.

[0058] In the embodiments of the present application, when the distance L1 between the current front beam 1 and the middle front beam 2 satisfies 80 mm ≤ L1 ≤ 160 mm, and / or when the distance L2 between the front front beam 1 and the middle front beam 2 satisfies 100 mm ≤ L2 ≤ 200 mm, the distance between the front front beam 1 and the middle front beam 2 in the second direction y is moderate, and the distance between the front front beam 1 and the middle front beam 2 in the third direction z is moderate, so that the two can approach and extend along the same straight line in the first direction x, thereby improving the anti-deformation ability of the overall frame when bearing external forces. At the same time, the distances between the front front beam 1 and the middle front beam 2 in the second direction y and the third direction z can also be used for installing the battery pack and other components or routing wires, so as to play a role in avoidance. Thus, while ensuring that the frame has strong structural strength, the utilization rate of the vehicle interior space is improved, the layout of the battery pack and other components is more reasonable and more compact, and further the number of other installation components used is reduced, so as to further improve the integration of the vehicle and reduce the production cost of the vehicle.

[0059] In a specific embodiment, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the frame further includes a reinforcing plate 4, and the reinforcing plate 4 is installed in the third groove 31 and fits with at least part of the inner wall of the third groove 31 to form a cavity 5.

[0060] In the embodiments of the present application, the reinforcing plate 4 can be welded to the bottom wall and at least part of the side walls of the third groove 31 to improve the stability and reliability of the connection between the reinforcing plate 4 and the connecting beam 3, thereby improving the structural strength of the connecting beam 3, and further reducing the possibility of the connecting beam 3 deforming during the process of transmitting and dispersing external forces, and then ensuring the smoothness of the external force during the transmission process.

[0061] Specifically, along the second direction y, the reinforcing plate 4 is welded to the side wall of the third groove 31 away from the support portion 33, so that the reinforcing plate 4 can enclose a cavity 5 with the inner wall of the third groove 31. The setting of the cavity 5 can not only further improve the structural strength of the connecting beam 3, but also form a channel for transmitting external forces, which is convenient for absorbing external forces and transmitting them along the first direction x to the middle front beam 2 when the frame bears external forces, thereby improving the safety collision performance of the frame.

[0062] In a possible embodiment, along the third direction z, the cross-sectional shape of the reinforcing plate 4 can be an L-shaped structure for easy processing.

[0063] In a specific embodiment, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, along the second direction y, the reinforcing plate 4 is spaced from the support portion 33.

[0064] In the embodiment of the present application, the reinforcing plate 4 and the supporting portion 33 are arranged at intervals in the second direction y, so that after the installation of the reinforcing plate 4, the third groove 31 can be divided into a first region (not marked in the figure) and a second region (not marked in the figure) in the second direction y. The first region can be the region between the reinforcing plate 4 and the supporting portion 33, and the second region can be the region between the reinforcing plate 4 and the side wall of the third groove 31 on the side away from the supporting portion 33 (i.e., the above-mentioned cavity 5).

[0065] Moreover, since the reinforcing plate 4 is welded to the side wall of the third groove 31 on the side away from the supporting portion 33, the whole reinforcing plate 4 can extend along the extending direction of the connecting beam 3, so that the first region and the second region also extend along the extending direction of the connecting beam 3, that is, the extending directions of the first region and the second region are the same as the direction of the external force transmitted by the connecting beam 3, which is beneficial to improving the structural strength of the connecting beam 3 while ensuring the transmission effect of the external force.

[0066] Specifically, during the process of the connecting beam 3 transmitting the external force, the external force can be dispersed through the reinforcing plate 4, so that a part of the external force is transmitted to the supporting portion 33 through the first region, and then transmitted to the inner panel of the sill through the supporting portion 33, and another part of the external force is transmitted to the center sill 2 through the second region, thereby realizing the transmission and dispersion of the external force.

[0067] At the same time, the arrangement of the reinforcing plate 4 and the supporting portion 33 at intervals in the second direction y can also play an avoidance role, so as to facilitate the installation or wiring of other components in the vehicle, thereby further improving the space utilization rate of the vehicle frame.

[0068] In a specific embodiment, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the reinforcing plate 4 includes a main body portion 43 and a first extension portion 41 and a second extension portion 42 connected to the main body portion 43. The main body portion 43 is installed in the third groove 31. Along the first direction x, the first extension portion 41 extends relative to the main body portion 43 into the first groove 11, and the second extension portion 42 extends relative to the main body portion 43 into the second groove 21.

[0069] In the embodiment of the present application, the first extension portion 41 can extend into the first groove 11 and be fixedly connected to the inner wall of the first groove 11, and the second extension portion 42 can extend into the second groove 21 and be fixedly connected to the inner wall of the second groove 21, so that the reinforcing plate 4 can be fixedly connected to the front crossmember 1, the center sill 2 and the connecting beam 3 at the same time, which is beneficial to improving the stability and reliability of the connection between the front crossmember 1, the center sill 2 and the connecting beam 3.

[0070] When subjected to external forces, the reinforcing plate 4 extending to the front main beam 1 and the middle main beam 2 can play a guiding role in the transmission of external forces, enabling the external forces to be transmitted in a preset direction. Specifically, during the transmission of external forces, the front anti-collision beam transmits the external forces to the front main beam 1. Since the first extension portion 41 of the reinforcing plate 4 extends into the first groove 11 of the front main beam 1 and the second extension portion 42 of the reinforcing plate 4 extends into the second groove 21 of the middle main beam 2, part of the external forces can be transmitted from the front main beam 1 to the middle main beam 2 through the reinforcing plate 4 along the extension direction of the reinforcing plate 4, reducing the possibility of deviation of this part of the external forces during transmission, thereby reducing the possibility of deformation of the front main beam 1, the middle main beam 2, and the connecting beam 3 during the transmission of external forces, improving the structural strength of the three, enhancing the structural stability of the vehicle frame, and further ensuring the safety of the passenger compartment.

[0071] In a specific embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the reinforcing plate 4 further includes reinforcing ribs 44, which protrude relative to the bottom of the reinforcing plate 4 and extend along the first direction x.

[0072] In the embodiments of the present application, by providing the reinforcing ribs 44, the structural strength of the reinforcing plate 4 can be improved to reduce the possibility of deformation of the reinforcing plate 4 when the vehicle frame is subjected to external forces, and the connection strength between the front main beam 1, the middle main beam 2, and the connecting beam 3 can also be improved. At the same time, at least part of the reinforcing ribs 44 extends along the first direction x, which is beneficial to further reducing the possibility of deviation of the external forces from the preset transmission path during transmission along the reinforcing plate 4 and improving the transmission effect of the external forces along the first direction x by the reinforcing plate 4.

[0073] In a specific embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, there are multiple reinforcing ribs 44, and the multiple reinforcing ribs 44 are spaced apart along the first direction x. The reinforcing ribs 44 are one or more of straight and curved types.

[0074] In the embodiments of the present application, the multiple reinforcing ribs 44 are spaced apart along the first direction x, which can avoid the formation of stress concentration points between adjacent two reinforcing ribs 44, thereby improving the structural strength of the reinforcing ribs 44, optimizing and enhancing the stress-bearing performance of the reinforcing ribs 44, reducing the safety hazard of cracking caused by vibration and impact, being beneficial to improving the service life of the reinforcing plate 4, and also being able to achieve the purpose of reducing the weight of the whole vehicle.

[0075] Specifically, the reinforcing ribs 44 located in the first extension portion 41 are distributed and extended along the first direction x, the reinforcing ribs 44 located in the second extension portion 42 are distributed and extended along the first direction x, and the reinforcing ribs 44 located in the main body portion 43 are distributed and extended along the extension direction of the main body portion 43. Among them, each reinforcing rib 44 can be one or more of a straight line type and a curve type, which can not only reduce the processing difficulty of the reinforcing rib 44, but also ensure the transmission of external force along its extension direction.

[0076] A vehicle includes a chassis and a vehicle frame, and the vehicle frame is the vehicle frame described above. Among them, the chassis includes a swing arm, and during the vehicle assembly process, the swing arm is cooperatively connected with the connecting beam 3.

[0077] In the embodiment of the present application, by adopting the above vehicle frame, the overall structural strength and stiffness of the vehicle can be improved, the number of components and the number of welding points used during the vehicle assembly process are reduced, the errors accumulated by welding are eliminated, and the dimensional chain error is reduced, thereby improving the overall vehicle quality while reducing the production cost. At the same time, the connecting beam 3 of the vehicle frame can also integrate the function of installing the chassis, so that the swing arm of the chassis is installed on the connecting beam 3 of the vehicle frame. Specifically, the installation point of the swing arm can be located between the reinforcing plate 4 and the support portion 33, so that during the vehicle driving process, the external force borne by the swing arm can also be transmitted and dispersed through the connecting beam 3, thereby improving the smoothness of the vehicle during driving and the comfort of passengers.

[0078] The structure, features and effects of the present application have been described in detail based on the embodiments shown in the drawings. The above is only the preferred embodiment of the present application, but the present application is not limited to the implementation scope shown in the drawings.
