Description

Technical Field

[0001] The present invention relates to the technical field of vehicle frame assemblies, and in particular to a standardized vehicle frame structure and a vehicle. Background Art

[0002] In the prior art, the frame structure is the basis for the assembly of the vehicle. In the traditional frame structure, the mounting holes on the longitudinal beam are individually designed according to the type of vehicle and the functions equipped. Moreover, in the same vehicle model, due to the different specifications and sizes of the vehicles, in order to adapt to the changes in size and balance the load distribution of the frame structure, the installation positions of components such as the crossbeam and axle in the frame structure are also different.

[0003] Therefore, the installation hole positions, hole diameters, and hole positioning of the longitudinal beams in different vehicle models are completely different, which makes it difficult to universally design the frame structures of different vehicles. When developing and designing new vehicles, it is impossible to quickly complete the variant design. The existing frame structure has a wide variety of parts and components that cannot be standardized, and the process needs to be frequently adjusted during processing and manufacturing. This also leads to the extremely low versatility of the existing frame structure. When modifying the vehicle or expanding the vehicle specifications in the later stage, the frame structure needs to be replaced and modified to a large extent, which greatly increases the research and development, manufacturing, and after-sales costs of the frame structure. Summary of the invention

To this end, the present invention provides a standardized frame structure of a vehicle and a vehicle, so as to achieve the purpose of standardizing vehicle parts based on the frame structure, improving the versatility of the frame structure, and reducing the difficulty of production and assembly and the manufacturing cost.

[0007] According to a standardized vehicle frame structure provided by the present invention, in the length direction of the longitudinal beam assembly, the left and right longitudinal beams are configured as a front section, a transition section and a body section sequentially connected from front to rear; The body section is parallel to the front section and offset toward the notch direction of the front section. The transition section obliquely connects the front section and the body section to make the longitudinal beam assembly wider at the front end and narrower at the rear end.

[0008] A standardized vehicle frame structure provided by the present invention further includes a beam seat installed at the rear end of the longitudinal beam assembly, which is used to improve the bending and torsional strength of the rear axle of the vehicle; The beam seat is made of a plate and is formed into a flange and a lining plate by stamping and bending. The lining plate is provided with a plurality of connection holes arranged in a matrix and is closely connected to the web. The flange is located on one side of the lining plate close to the folded edge and is perpendicular to the lining plate.

[0009] According to a standardized vehicle frame structure provided by the present invention, the width of the flange gradually decreases from the middle to both ends along its length direction, and at least the middle portion of the flange protrudes from the folded edge.

[0010] A standardized vehicle frame structure provided by the present invention further includes a lining strip installed on the longitudinal beam assembly. The lining strip has the same thickness as the lining plate and is provided with a plurality of connection holes arranged in a matrix.

[0011] According to a standardized vehicle frame structure provided by the present invention, the left and right longitudinal beams are made of plates of different thicknesses, and the thickness of the web gradually decreases from the middle to both ends in its own length direction.

[0012] According to a standardized vehicle frame structure provided by the present invention, in the length direction of the web, the width of the web gradually decreases from the middle to both ends.

[0013] A standardized vehicle frame structure according to the present invention further includes a subframe connection assembly, wherein the subframe connection assembly is mounted on the outer side surface of the longitudinal beam assembly; The lower end of the sub-frame connecting assembly is provided with a plurality of connecting holes arranged in a matrix and is closely connected to the web, and the upper end of the sub-frame connecting assembly protrudes upward from the longitudinal beam assembly.

[0014] In a second aspect, the present invention further provides a vehicle, comprising a vehicle body, wherein the vehicle body is arranged above the standardized vehicle frame structure as described above.

[0015] The above one or more technical solutions in the present invention have at least one of the following technical effects: By opening through holes distributed in a matrix on the longitudinal beam assembly, the whole vehicle assembly operation is based on the frame structure to achieve interface standardization and modularization of the frame structure.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0031] In the embodiments of the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0033] In the prior art, the frame structure is the basis for the assembly of the whole vehicle. In the traditional frame structure, the mounting holes on the longitudinal beam are individually designed according to the type of vehicle and the functions equipped. Moreover, in the same vehicle model, due to the different specifications and sizes of the vehicles, in order to adapt to the changes in size and balance the load distribution of the frame structure, the installation positions of components such as the crossbeam and axle in the frame structure are also different. Therefore, the installation hole position, hole diameter and hole positioning of the longitudinal beam in different vehicle models are completely different, which makes it difficult to universally design the frame structure of different vehicles.

[0034] like Figures 1 to 6 As shown, in the embodiment of the present invention, a standardized frame structure of a vehicle is introduced to achieve the purpose of improving the versatility of the frame structure and reducing the difficulty of production and assembly and the manufacturing cost.

[0035] The standardized frame structure mainly includes a longitudinal beam assembly 100 and a cross beam assembly 200. The longitudinal beam assembly 100 is provided with a left longitudinal beam 110 and a right longitudinal beam 120 which are symmetrically and parallelly distributed. The cross beam assembly 200 is located between the left longitudinal beam 110 and the right longitudinal beam 120. The cross beam assembly 200 is connected to the left longitudinal beam 110 and the right longitudinal beam 120 respectively.

[0036] In particular, the left and right longitudinal beams are formed by bending a plate to form a channel structure, wherein the channel bottom of the channel structure is a web 111 and the channel wall is a folded edge 112 .

[0037] like Figure 5 As shown, the web 111 is provided with a plurality of through holes 113 evenly distributed on the entire plate surface and arranged in a matrix, so as to conveniently adjust the position of the cross beam assembly 200 in the length direction of the longitudinal beam assembly 100 .

[0038] Furthermore, the standardized frame structure includes a wing beam assembly, a tail beam assembly and a subframe connection assembly 500. They are all mounted on the web 111 through fasteners. Moreover, the standardized frame structures of different lengths can be universally used to achieve product serialization design.

[0039] The cross beam assembly 200, the wing beam assembly, and the tail beam assembly are fixedly connected to the left and right longitudinal beams by standard bolts to form a frame structure. Overall, the cross beam assembly 200 is evenly distributed in the middle area of ​​the frame assembly. The wing beam assembly connects the middle and rear area of ​​the frame, and the tail beam assembly is closed at the rear end of the frame, ensuring that the frame assembly has good bending and torsion resistance.

[0040] Preferably, the flying wing beam assembly is located at the center of the rear axle of the vehicle.

[0041] like Figure 2 and Figure 3 As shown, the left longitudinal beam 110 and the right longitudinal beam 120 are configured as groove structures with equal cross-sections. The through holes 113 on the web 111 are arranged at equal intervals between adjacent hole positions and the apertures of the through holes 113 are the same, thereby ensuring that the components between different vehicle models are mutually compatible. In addition, the left and right longitudinal beams can be made of materials such as high-strength steel, hot-formed steel, and magnesium-aluminum alloy. Preferably, the thickness of the plate used to make the left and right longitudinal beams ranges from 4 mm to 10 mm, and the material grade is 500L to 700L.

[0042] Furthermore, 2 to 5 groups of crossbeam assemblies 200 may be arranged between the left longitudinal beam 110 and the right longitudinal beam 120. The length variation of the standardized frame structure may be matched by adjusting the installation position and quantity of the crossbeam assemblies 200, thereby realizing a variant design of the vehicle. The crossbeam assembly 200 is a high-strength steel stamping and riveting structure crossbeam.

[0043] Preferably, the matrix through holes 113 evenly arranged on the web 111 have a spacing of 50 mm in the length direction of the web 111 and a spacing of 60 mm in the width direction of the web 111. In addition, the diameter of the through holes 113 can be uniformly 14.5 mm, 15.5 mm, 17.5 mm, etc. according to the requirements of different vehicle models.

[0044] When a plurality of through holes 113 arranged in a matrix are formed on the web 111 , punches arranged in a matrix are abutted against the plate surface of the web 111 , and then all punches are punched uniformly to complete the process of opening holes on the web 111 at one time.

[0045] In this embodiment, by providing through holes 113 distributed in a matrix on the longitudinal beam assembly 100, the whole vehicle assembly operation realizes interface standardization based on the frame structure and modularizes the frame structure. In the variant development and design of the vehicle, the vehicle can be rapidly modified by simple module replacement and adjustment, thereby achieving diversification of vehicle specifications. The standardized frame structure can not only make vehicle maintenance simpler and faster, but also make the same parts applicable to a variety of models, improve the versatility in multiple models, reduce the number of new parts required for the development of new vehicles, and thus reduce the vehicle manufacturing cost and assembly difficulty.

[0046] Based on the above embodiment, in another embodiment of the present invention, a standardized frame structure is introduced.

[0047] The left longitudinal beam 110 and the right longitudinal beam 120 are disposed facing each other with their respective notches. The end of the cross beam assembly 200 extends into the notch and is connected to the web 111 .

[0048] Specifically, the notch of the left longitudinal beam 110 and the notch of the right longitudinal beam 120 are disposed toward the space between the left longitudinal beam 110 and the right longitudinal beam 120 .

[0049] The standardized frame structure also includes a wing beam assembly, a tail beam assembly and a subframe connection assembly 500. Moreover, the cross beam assembly 200, the wing beam assembly, the tail beam assembly and the subframe connection assembly 500 are all provided with connection holes arranged in a matrix, which are used to be fixedly connected to the longitudinal beam assembly 100. In this way, when the vehicle is modified, components can be directly added without drilling holes, or the positions of the cross beam assembly 200, the tail beam assembly and the subframe connection assembly 500 relative to the longitudinal beam assembly 100 can be adjusted, thereby maximizing the modification versatility of the vehicle.

[0050] like Figure 4As shown, the crossbeam assembly 200 at least includes a crossbeam body 210, a crossbeam upper flange plate 221 and a crossbeam lower flange plate 222. The crossbeam upper and lower flange plates are provided with a plurality of connection holes arranged in a matrix. The spacing between adjacent connection holes is the same as the spacing between the through holes 113. The through holes 113 are arranged at equal intervals of 50 mm along the length direction of the web 111, and are arranged at equal intervals of 60 mm along the width direction of the web 111.

[0051] The upper and lower flange plates of the cross beam are connected to the left and right longitudinal beams by bolts / rivets. For example, the web 111 is provided with through holes 113 with a lengthwise spacing of 50 mm multiples and a hole diameter of 15.5 mm. Correspondingly, the connection holes on the upper and lower flange plates of the cross beam can be standard holes with a transverse spacing of 50 mm and a diameter of 15.5 mm, so as to be assembled with the web 111.

[0052] In particular, the upper end of the crossbeam assembly 200 is arranged horizontally, and the lower end is arranged in an upward arch shape. Specifically, when the crossbeam assembly 200 is installed in the standardized frame structure, its upper end is lower than the upper surface of the left and right longitudinal beams, and its lower end is higher than the lower surface of the left and right longitudinal beams to form an arched space. Therefore, the upper edge of the crossbeam assembly 200 does not exceed the uppermost end of the frame longitudinal beam, and does not affect the installation of the vehicle body and other components above the frame structure. The upward arched arc space at the lower end of the crossbeam assembly 200 can accommodate the transmission shaft arranged parallel to the length direction of the longitudinal beam assembly 100, and will not hinder the movement of the transmission shaft.

[0053] The crossbeam body 210 can be formed into an integrated stamped structure by stamping and bending a plate.

[0054] The cross beam body 210 can be made into an integrated casting structure by casting. The cross beam body 210 adopts a hollow interior and a gradual thickness structure of the outer wall to achieve a lightweight design. In addition, the cross beam connecting plate is correspondingly set to a gradual cross-section structure.

[0055] In this embodiment, the standardized frame structure is modularly designed to ensure that each module is universal in a variety of vehicle models, realize rapid vehicle design variations, and reduce vehicle R&D and manufacturing costs. The standardized frame structure can be mass-produced, improving production efficiency. At the same time, subsequent technical upgrades can also be carried out based on the standardized frame structure for product iteration, greatly reducing vehicle development costs.

[0056] Based on the above embodiment, in another embodiment of the present invention, a standardized frame structure is introduced.

[0057] In the length direction of the longitudinal beam assembly 100 , the left and right longitudinal beams are configured as a front section 114 , a transition section 115 , and a body section 116 which are sequentially connected from front to rear.

[0058] The body section 116 is parallel to the front section 114 and offset toward the notch direction of the front section 114. The transition section 115 obliquely connects the front section 114 and the body section 116, so as to make the longitudinal beam assembly 100 wider at the front end and narrower at the rear end.

[0059] The standardized frame structure is generally a trapezoidal structure with a wide front and narrow rear. The front end is widened to accommodate the large engine layout, and the rear end is narrowed to meet the 2550mm width limit regulations for the vehicle.

[0060] Specifically, the body section 116 is offset from the groove bottom to the groove opening along the normal direction of the web 111 relative to the front section 114. Thus, the longitudinal beam assembly 100 is configured as a trapezoidal structure with a front width greater than a rear width, which can be used to install a large-volume engine.

[0061] Based on the above embodiment, in another embodiment of the present invention, a standardized frame structure is introduced.

[0062] like Figure 1 and Figure 6 As shown, the standardized vehicle frame structure further includes a beam seat 300 installed at the rear end of the longitudinal beam assembly 100 to improve the bending and torsional strength of the rear axle of the vehicle.

[0063] The beam seat 300 is made of a plate and is formed into a flange 312 and a lining plate 311 by stamping and bending. The lining plate 311 is provided with a plurality of connection holes arranged in a matrix and is connected to the web 111. The spacing between adjacent connection holes and the spacing between the through holes 113 are of the same size. The through holes 113 are arranged at equal intervals of 50 mm along the length direction of the web 111 and at equal intervals of 60 mm along the width direction of the web 111.

[0064] Moreover, the flange 312 is located at one side of the lining plate 311 close to the folded edges 112 of the left and right longitudinal beams. Moreover, the flange 312 is perpendicular to the lining plate 311 .

[0065] Furthermore, the beam seat 300 is provided with large and small beam seats of different sizes. The small beam seat 310 and the large beam seat 320 are arranged in pairs and are respectively connected to the folding edges 112 located on the upper and lower sides of the longitudinal beam assembly 100. In addition, the small beam seat 310 is located above the large beam seat 320.

[0066] Preferably, the width of the flange 312 gradually decreases from the middle to both ends along its length direction, and at least the middle portion of the flange 312 protrudes from the folded edge 112 .

[0067] Based on the above embodiment, in another embodiment of the present invention, a standardized frame structure is introduced.

[0068] The standardized vehicle frame structure further includes a lining strip 400 installed on the longitudinal beam assembly 100. The lining strip 400 has the same thickness as the lining plate 311 and is provided with a plurality of connection holes arranged in a matrix. The spacing between adjacent connection holes is the same as the spacing between the through holes 113. The through holes 113 are arranged at equal intervals of 50 mm along the length direction of the web 111 and at equal intervals of 60 mm along the width direction of the web 111.

[0069] Based on the above embodiment, in another embodiment of the present invention, a standardized frame structure is introduced.

[0070] Specifically, the left and right longitudinal beams are made of plates of unequal thickness, and the thickness of the web 111 gradually decreases from the middle to both ends in its own length direction. In this way, the cross-sectional thickness of the left and right longitudinal beams can be designed as a cross-sectional structure of unequal thickness according to the load-bearing capacity requirements of the vehicle model, so as to achieve local reinforcement of the left and right longitudinal beams.

[0071] Furthermore, if Figure 5 As shown, in the length direction of the web 111, the width of the web 111 gradually decreases from the middle to both ends. In this way, the cross-sectional heights of the left and right longitudinal beams can be designed as unequal height cross-sectional structures according to the load-bearing requirements of the vehicle model, thereby realizing local reinforcement of the left and right longitudinal beams.

[0072] Based on the above embodiment, in another embodiment of the present invention, a standardized frame structure is introduced.

[0073] The standardized frame structure includes a subframe connection assembly 500. The subframe connection assembly 500 is installed on the outer side of the longitudinal beam assembly 100. The lower end of the subframe connection assembly 500 is provided with a plurality of connection holes arranged in a matrix and is closely connected to the web 111, and the upper end of the subframe connection assembly 500 protrudes upward from the longitudinal beam assembly 100.

[0074] The subframe connection assembly 500 specifically includes a subframe front connection device 510, a subframe middle connection device, and a subframe rear connection device 530, which are used to install the subframe on a standardized frame structure to ensure standardization of the modification.

[0075] Specifically, when fixing the subframe, the front, middle and rear connecting devices of the subframe are respectively attached to the web 111 of the longitudinal beam and protrude upward from the top surface of the longitudinal beam assembly 100, which can widen the spacing between the frame structure and the subframe connection point and increase the torque effect.

[0076] In another embodiment of the present invention, a vehicle adopting the above-mentioned standardized frame structure is introduced.

[0077] The vehicle comprises a body and a subframe, wherein the body is arranged on top of a standardized frame structure.

[0078] Specifically, the subframe is installed in the middle and rear area of ​​the standardized frame structure, and is fixedly connected to the longitudinal beam assembly 100 through the subframe connection assembly 500 .

[0079] In particular, the standardized frame structure includes a crossbeam assembly 200, a wing beam assembly, a tail beam assembly and a subframe connection assembly 500. Among them, the wing beam assembly includes a wing beam and a wing beam flange 312 plate. The wing beam is an integrally cast rectangular tubular crossbeam. The wing beam is made of a material with a grade of QT700 or QT800. The upper end of the wing beam is designed with a rear suspension thrust rod mounting seat and a connecting plate mounting seat. The wing beam flange 312 plate is provided with a plurality of connection holes arranged in a matrix. The spacing between adjacent connection holes is the same size as the spacing between the through holes 113. The through holes 113 are arranged at equal intervals of 50 mm along the length direction of the web 111, and are arranged at equal intervals of 60 mm along the width direction of the web 111.

[0080] The tail beam assembly is made of a plate through integrated stamping and bending, and is stamped from a whole piece of steel plate, and has excellent processability and lightweight performance. A plurality of connection holes arranged in a matrix are provided on the side of the tail beam assembly. The spacing between adjacent connection holes and the spacing between the through holes 113 are of the same size. Thus, the tail beam assembly is directly connected to the left and right longitudinal beams without the need for additional connection plates, thereby improving production efficiency and the lightweight level of the standardized frame structure.

[0081] In this embodiment, based on the standardized frame structure, the body, engine and other components are designed, manufactured and assembled in coordination with it, which can improve the versatility of the components in the vehicle, reduce the cost of variant design of the vehicle, and reduce the types of components. This simplifies the supply chain system required for vehicle production, reduces the tooling and fixtures in the production and assembly process, and reduces the vehicle manufacturing cost. It realizes the flexible production of vehicle products, shortens the vehicle development cycle, reduces the waste caused by vehicle product iteration, can quickly launch products with personalized characteristics, and improves the core competitiveness of the vehicle.

[0082] Based on the above embodiment, another embodiment of the present invention introduces a crossbeam assembly 200 for a standardized vehicle frame structure. Figure 7 and Figure 8 As shown, the cross-beam assembly 200 includes a cross-beam body 210 and a cross-beam bracket 220 .

[0083] Specifically, the beam body 210 is provided with a planar top plate 211, a curved bottom plate 212, and a rib plate 213 supported between the top plate 211 and the bottom plate 212. One end of the beam bracket 220 is connected to the beam body 210, and the other end of the beam bracket 220 is cantilevered outside the beam body 210 along the length direction of the beam body 210.

[0084] The top plate 211 and the bottom plate 212 are respectively connected to the rib plate 213 vertically and are located on the same side of the plate surface of the rib plate 213 , forming a symmetrical arch shape.

[0085] The beam supports 220 are arranged in pairs and symmetrically on the top plate 211 and / or the bottom plate 212 .

[0086] In this embodiment, an arched crossbeam body 210 is formed by a top plate 211, a bottom plate 212 and a rib plate 213, which not only realizes a lightweight design of the crossbeam assembly 200, but also forms an arched space at the lower end of the frame structure so that the transmission shaft can be better accommodated in the frame structure.

[0087] Based on the above embodiment, in another embodiment of the present invention, a cross beam assembly 200 for a standardized vehicle frame structure is introduced.
