[0026] The following is combined with Figures 1-6 The front cabin frame structure 10, the body 100, and the vehicle according to embodiments of the present utility model are described in detail.

[0027] Reference Figure 1 and Figure 2 As shown, according to an embodiment of the present invention, the front cabin frame structure 10 is used for the vehicle body 100. The front cabin frame structure 10 includes: a front frame assembly 1, a left connecting assembly 2, and a right connecting assembly 3. In the length direction of the vehicle body 100, the front frame assembly 1 is opposite to and spaced apart from the front bulkhead 20 of the vehicle body 100. The left connecting assembly 2 includes: an upper left member 21 and a lower left member 22. In the length direction of the vehicle body 100, i.e. Figure 1 and Figure 2 In the front-rear direction, the upper left component 21 is connected to the front frame assembly 1 and the left side A-pillar 30 of the body 100, respectively; the lower left component 22 is connected to the front frame assembly 1 and the left side A-pillar 30 of the body 100, respectively. In the height direction of the body 100, i.e. Figure 1 and Figure 2In the vertical direction, the upper left component 21 is located above the lower left component 22, in the width direction of the vehicle body 100, that is... Figure 1 and Figure 2 In the left and right direction, the right connecting component 3 and the left connecting component 2 are opposite to each other and spaced apart. The right connecting component 3 includes an upper right component 31 and a lower right component 32. In the length direction of the vehicle body 100, the upper right component 31 is connected to the front frame component 1 and the right side A-pillar 40 of the vehicle body 100 respectively. The lower right component 32 is connected to the front frame component 1 and the right side A-pillar 40 of the vehicle body 100 respectively. In the height direction of the vehicle body 100, the upper right component 31 is located above the lower right component 32.

[0028] It is understood that the front frame assembly 1 is positioned opposite and spaced apart from the front bulkhead 20 of the body 100. The upper left component 21 connects the front frame assembly 1 and the left side A-pillar 30 of the body 100, and the lower right component 32 connects the front frame assembly 1 and the right side A-pillar 40 of the body 100. The front cabin frame structure 10 can form a closed frame structure with the front bulkhead 20, the left side A-pillar 30, and the right side A-pillar 40 of the body 100. Furthermore, the left side A-pillar 30 and the right side A-pillar 40, which have higher strength and rigidity, can reinforce the front cabin frame structure 10. The front compartment frame structure 10 is reliably supported to improve the positional accuracy of the mounting points for components, thereby improving the installation accuracy of the components. When the vehicle collides at the front, the impact force generated by the collision is transmitted to the front compartment frame structure 10 and can be transmitted to the left A-pillar 30 and the right A-pillar 40. The left A-pillar 30 and the right A-pillar 40 can effectively resist the impact force, which helps to maintain the structural integrity of the front compartment frame structure 10 and helps to ensure the safety of the occupants.

[0029] According to the front cabin frame structure 10 implemented by this utility model, its upper left component 21 is connected to the left side A-pillar 30 and its upper right component 31 is connected to the right side A-pillar 40. The left side A-pillar 30 and the right side A-pillar 40, which have high strength and rigidity, can reliably support the front cabin frame structure 10, thereby improving the positional accuracy of the front cabin frame structure 10 and the positional accuracy of the mounting points of the front cabin frame structure 10 for installing components, which is conducive to improving the installation accuracy of the components installed on the front cabin frame structure 10.

[0030] In some embodiments of this utility model, the upper left component 21 has a left hinge mounting hole for the hood, and the upper right component 31 has a right hinge mounting hole for the hood. The left A-pillar 30 and the right A-pillar 40 have high strength and rigidity, and strong load-bearing capacity. The risk of deformation of the left A-pillar 30 and the right A-pillar 40 is small. By connecting the upper left component 21 to the left A-pillar 30 and the upper right component 31 to the right A-pillar 40, the high strength and rigidity of the left A-pillar 30 and the right A-pillar 40 can reliably support the upper left component 21 and the upper right component 31, respectively. This is beneficial to improving the positional accuracy of the upper left component 21 and the upper right component 31, and thus to improving the positional accuracy of the left and right hinge mounting holes for the hood. This allows the left and right hinges of the hood to be accurately installed in the preset positions, which helps to control the gap surface difference between the hood and other vehicle components, and improves the assembly quality of the vehicle.

[0031] In some embodiments of this utility model, reference is made to Figure 1 , Figure 3 and Figure 4 As shown, the lower left component 22 is also adapted to be connected to the left front wheel arch 50 of the vehicle body 100, and the lower right component 32 is also adapted to be connected to the right front wheel arch 60 of the vehicle body 100. The left front wheel arch 50 can support the lower left component 22, and the right front wheel arch 60 can support the lower right component 32. This can improve the load-bearing capacity of the lower left component 22 and the lower right component 32, reduce the risk of deformation of the lower left component 22 and the lower right component 32, and improve the structural stability of the front cabin frame structure 10.

[0032] Reference Figure 1 , Figure 3 and Figure 4 As shown, both the left front wheel arch 50 and the right front wheel arch 60 are connected to the lower reinforcing beam 202 of the front bulkhead 20. The lower reinforcing beam 202 has high strength and rigidity, which is beneficial to reliably support the left front wheel arch 50 and the right front wheel arch 60, improve the load-bearing capacity of the left front wheel arch 50 and the right front wheel arch 60, and reduce the risk of deformation of the left front wheel arch 50 and the right front wheel arch 60. The left front wheel arch 50 and the right front wheel arch 60 can reliably support the lower left component 22 and the lower right component 32 respectively, so as to improve the structural stability of the front cabin frame structure 10.

[0033] In some embodiments of this utility model, reference is made to Figure 1 and Figure 5As shown, the front cabin frame structure 10 also includes: a left mounting bracket 4 and a right mounting bracket 5. The left mounting bracket 4 is connected to the lower left component 22 and has a left accessory mounting hole 41. The right mounting bracket 5 is connected to the lower right component 32 and has a right accessory mounting hole. The left accessory mounting hole 41 and the right accessory mounting hole can be used to install vehicle accessories, such as headlights, bumpers, and fenders.

[0034] Understandably, both the lower left component 22 and the lower right component 32 are connected to the side A-pillar of the vehicle body 100. The lower left component 22 is indirectly connected to the lower reinforcing beam 202 of the bulkhead via the left front wheel arch 50, and the lower right component 32 is indirectly connected to the lower reinforcing beam 202 of the bulkhead via the right front wheel arch 60. This allows the lower left component 22 and the lower right component 32 to be reliably supported, which helps to improve the load-bearing capacity of the lower left component 22 and the lower right component 32, and reduces the risk of deformation of the lower left component 22 and the lower right component 32. This, in turn, helps to improve the positional accuracy of the left mounting bracket 4 installed on the lower left component 22 and the right mounting bracket 5 installed on the lower right component 32, and further helps to improve the positional accuracy of the left accessory mounting hole 41 and the right accessory mounting hole, so as to facilitate the precise installation of accessories.

[0035] In some embodiments of this utility model, reference is made to Figure 1 and Figures 3-5 As shown, the lower left component 22 includes: a lower left crossbeam 221, a lower left connecting beam 222, and a lower left longitudinal beam 223. The lower left longitudinal beam 223 is adapted to be connected to the left front wheel arch 50 and the left side A-pillar 30. The lower left longitudinal beam 223 has a lower left adjustment area 22311 extending along the length of the vehicle body 100. One end of the lower left connecting beam 222 is connected to any position of the lower left adjustment area 22311. The other end of the lower left connecting beam 222 is adapted to be connected to the front frame assembly 1 through the lower left crossbeam 221. The left mounting bracket 4 is connected to the lower left crossbeam 221.

[0036] Understandably, referring to Figure 1 As shown, the lower left longitudinal beam 223 is connected to the left front wheel arch 50 and the left side A-pillar 30. The left front wheel arch 50 and the left side A-pillar 30 can jointly support the lower left longitudinal beam 223. When the lower left longitudinal beam 223 is subjected to load, the load can be distributed to the left front wheel arch 50 and the left side A-pillar 30, avoiding excessive stress on either the left front wheel arch 50 or the left side A-pillar 30 and deformation. This helps to improve the positional accuracy of the lower left longitudinal beam 223, improve the positional accuracy of the lower left crossbeam 221 connected to the lower left longitudinal beam 223, and improve the positional accuracy of the left mounting bracket 4 installed on the lower left crossbeam 221. This, in turn, helps to improve the positional accuracy of the left accessory mounting hole 41, so as to facilitate the precise installation of accessories.

[0037] During assembly of the vehicle body 100, by adjusting the connection position between the lower left connecting beam 222 and the lower left adjustment area 22311 along the length of the vehicle body 100, the position of the connection point of the lower left connecting beam 222 for connecting to the lower left crossbeam 221 can be adjusted. This allows for adjustment of the position of the left mounting bracket 4 connected to the lower left crossbeam 221, facilitating the installation of the left mounting bracket 4 to a preset position. This improves the positional accuracy of the left accessory mounting hole 41 along the length of the vehicle body 100, thus improving the positional accuracy of the left accessory mounting hole 41 and facilitating the precise installation of accessories. The lower left connecting beam 222 and the lower left adjustment area 22311 can be connected by welding. When the lower left connecting beam 222 is welded to the lower left adjustment area 22311, tooling fixtures can be used to ensure the positional accuracy of the lower left connecting beam 222, reducing the impact of positional errors of other components on the positional accuracy of the lower left connecting beam 222. This, in turn, helps ensure the positional accuracy of the lower left crossbeam 221, thereby ensuring the positional accuracy of the left mounting bracket 4.

[0038] Reference Figure 6 As shown, the left mounting bracket 4 has multiple first connecting holes 42, and the lower left crossbeam 221 has second connecting holes 2211 corresponding to the multiple first connecting holes 42. The first connecting holes 42 can be elongated holes extending along the width direction of the vehicle, and the second connecting holes 2211 can be threaded holes. Screws can be passed through the first connecting holes 42 and threaded into the second connecting holes 2211 to fix the left mounting bracket 4 to the lower left crossbeam 221. The elongated shape of the first connecting holes 42 allows for adjustment of the position of the left mounting bracket 4 in the width direction of the vehicle, so as to install the left mounting bracket 4 to a preset position. This helps to improve the positional accuracy of the left accessory mounting hole 41 in the width direction of the vehicle body 100, thereby improving the positional accuracy of the left accessory mounting hole 41 and facilitating the precise installation of accessories.

[0039] The lower right component 32 includes: a lower right crossbeam, a lower right connecting beam, and a lower right longitudinal beam. The lower right longitudinal beam is adapted to be connected to the right front wheel arch 60 and the right side A-pillar 40. The lower right longitudinal beam has a lower right adjustment area extending along the length of the vehicle body 100. One end of the lower right connecting beam is connected to any position of the lower right adjustment area. The other end of the lower right connecting beam is adapted to be connected to the front frame assembly 1 through the lower right crossbeam. The right mounting bracket 5 is connected to the lower right crossbeam.

[0040] It is understandable that the lower right longitudinal beam is connected to the right front wheel arch 60 and the right side A-pillar 40. The right front wheel arch 60 and the right side A-pillar 40 can jointly support the lower right longitudinal beam. When the lower right longitudinal beam is subjected to load, the load can be distributed to the right front wheel arch 60 and the right side A-pillar 40, avoiding excessive stress on either the right front wheel arch 60 or the right side A-pillar 40 and deformation. This helps to improve the positional accuracy of the lower right longitudinal beam, the positional accuracy of the lower right crossbeam connected to the lower right longitudinal beam, and the positional accuracy of the right mounting bracket 5 installed on the lower right crossbeam. This, in turn, helps to improve the positional accuracy of the right accessory mounting hole, so as to facilitate the precise installation of accessories.

[0041] During assembly of the vehicle body 100, by adjusting the connection position between the lower right connecting beam and the lower right adjustment area along the length of the vehicle body 100, the position of the connection point of the lower right connecting beam used to connect to the lower right crossbeam can be adjusted. This allows for adjustment of the position of the right mounting bracket 5 connected to the lower right crossbeam, facilitating the installation of the right mounting bracket 5 to a preset position. This improves the positional accuracy of the right accessory mounting hole along the length of the vehicle body 100, thus improving the positional accuracy of the right accessory mounting hole and facilitating the precise installation of accessories. The lower right connecting beam and the lower right adjustment area can be connected by welding. When the lower right connecting beam is welded to the lower right adjustment area, tooling fixtures can be used to ensure the positional accuracy of the lower right connecting beam, reducing the impact of positional errors of other components on the positional accuracy of the lower right connecting beam. This helps ensure the positional accuracy of the lower right crossbeam, thereby ensuring the positional accuracy of the right mounting bracket 5.

[0042] The right mounting bracket 5 has multiple third connecting holes, and the lower right crossbeam has a fourth connecting hole corresponding to each of the multiple third connecting holes. The third connecting holes can be elongated oval holes extending along the width direction of the vehicle, and the fourth connecting holes can be threaded holes. Screws can be passed through the third connecting holes and threaded into the fourth connecting holes to fix the right mounting bracket 5 to the lower right crossbeam. The elongated oval structure of the third connecting holes allows for adjustment of the position of the right mounting bracket 5 in the width direction of the vehicle, so as to install the right mounting bracket 5 to a preset position. This helps to improve the positional accuracy of the right accessory mounting hole in the width direction of the vehicle body 100, thereby improving the positional accuracy of the right accessory mounting hole and facilitating the precise installation of accessories.

[0043] In some embodiments of this utility model, reference is made to Figure 1 , Figure 3 and Figure 4As shown, the lower left longitudinal beam 223 includes a lower left adjustment section 2231 and a lower left reinforcing section 2232. The lower left adjustment section 2231 has a lower left adjustment area 22311. The lower left reinforcing section 2232 includes a lower left first reinforcing plate 22321 and a lower left second reinforcing plate 22322. The lower left first reinforcing plate 22321 and the lower left second reinforcing plate 22322 are connected and jointly define the lower left longitudinal beam cavity 22323 extending along the length direction of the vehicle body 100. The lower left first reinforcing plate 22321 and the lower left second reinforcing plate 22322 are both suitable for connection with the lower left adjustment section 2231, the left front wheel arch 50, and the left side A-pillar 30.

[0044] Understandably, the lower left first reinforcing plate 22321 and the lower left second reinforcing plate 22322 are connected and jointly define the lower left longitudinal beam cavity 22323 extending along the length of the vehicle body 100. This can increase the cross-sectional area of ​​the lower left reinforcing section 2232 perpendicular to the length of the vehicle body 100, which is beneficial to increasing the bending and torsional resistance of the lower left reinforcing section 2232 and improving its load-bearing capacity. When the front of the vehicle is hit by a collision, the lower left reinforcing section 2232 can effectively bear the impact force generated by the collision and reduce the risk of deformation of the lower left reinforcing section 2232.

[0045] Additionally, refer to Figure 1 As shown, in the front-rear direction, the distance from the left pillar 13 to the left side A-pillar 30 is a, and the length of the left lower longitudinal beam 223 is b. a and b satisfy the following relationship: 1 / 2a≤b≤4 / 5a. b is in the range of 1 / 2a~4 / 5a. The distance between the front end of the left lower longitudinal beam 223 and the left side A-pillar is relatively small. The left lower longitudinal beam 223 can be connected to the left lower crossbeam 221 further forward, which is beneficial to shorten the length of the left lower crossbeam 221, thereby improving the rigidity of the left lower crossbeam 221. This is beneficial to reliably support the left mounting bracket 4, and can significantly shorten the cantilever of the left accessory mounting hole 41. The left accessory mounting hole 41 is located further forward, which can meet the forward movement of different headlight and fender gaps and achieve more styling effects.

[0046] Among them, reference Figure 4 As shown, both the lower left first reinforcing plate 22321 and the lower left second reinforcing plate 22322 can be constructed as "U"-shaped plates, and the "U"-shaped openings of the lower left first reinforcing plate 22321 and the lower left second reinforcing plate 22322 are arranged opposite to each other. The lower left first reinforcing plate 22321 and the lower left second reinforcing plate 22322 together define the lower left longitudinal beam cavity 22323 of the rectangular structure, so as to strengthen the strength and stiffness of the lower left reinforcing section 2232 and improve the load-bearing capacity of the lower left reinforcing section 2232.

[0047] The lower right longitudinal beam includes a lower right adjustment section and a lower right reinforcement section. The lower right adjustment section has a lower right adjustment area. The lower right reinforcement section includes a lower right first reinforcement plate and a lower right second reinforcement plate. The lower right first reinforcement plate and the lower right second reinforcement plate are connected and together define the lower right longitudinal beam cavity extending along the length direction of the vehicle body 100. The lower right first reinforcement plate and the lower right second reinforcement plate are both suitable for connection with the lower right adjustment section, the right front wheel arch 60, and the right side A-pillar 40.

[0048] Understandably, the lower right first reinforcing plate and the lower right second reinforcing plate are connected and together define the lower right longitudinal beam cavity extending along the length of the vehicle body 100. This can increase the cross-sectional area of ​​the lower right reinforcing section perpendicular to the length of the vehicle body 100, which is beneficial to increasing the bending and torsional resistance of the lower right reinforcing section and improving its load-bearing capacity. When the front of the vehicle is hit by a collision, the lower right reinforcing section can effectively bear the impact force generated by the collision and reduce the risk of deformation of the lower right reinforcing section.

[0049] In addition, the lower right longitudinal beam extends forward of the vehicle body 100, and the lower right longitudinal beam can connect with the lower right cross beam further forward, which helps to shorten the length of the lower right cross beam, thereby improving the rigidity of the lower right cross beam and helping to reliably support the right mounting bracket 5. This allows for a significant reduction in the cantilever of the right accessory mounting hole, and the right accessory mounting hole is located further forward, which can accommodate the forward movement of different headlight and fender gaps, achieving more styling effects.

[0050] Both the lower right first reinforcing plate and the lower right second reinforcing plate can be constructed as "U"-shaped plates, and the "U"-shaped openings of the lower right first reinforcing plate and the lower right second reinforcing plate are arranged opposite each other. The lower right first reinforcing plate and the lower right second reinforcing plate together define the lower right longitudinal beam cavity of the rectangular structure, so as to strengthen the strength and stiffness of the lower right reinforcing section and improve the load-bearing capacity of the lower right reinforcing section.

[0051] In some embodiments of this utility model, reference is made to Figure 1 As shown, the upper left component 21 and the upper right component 31 are also adapted to be connected to the reinforcing crossbeam 201 on the front bulkhead 20 to further enhance the strength and rigidity of the front cabin frame structure 10. The reinforcing crossbeam 201 on the bulkhead can support the upper left component 21 and the upper right component 31, further enhancing the load-bearing capacity of the upper left component 21 and the upper right component 31 and reducing the risk of deformation of the upper left component 21 and the upper right component 31. This is beneficial to improving the positional accuracy of the left hinge mounting hole and the right hinge mounting hole of the engine hood, and thus beneficial to improving the installation accuracy of the engine hood.

[0052] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2As shown, the front frame assembly 1 is constructed as a rectangular frame structure. When the front of the vehicle is involved in a collision, the cross-sectional area of ​​the front frame assembly 1 with the rectangular frame structure in the direction perpendicular to the front and rear of the vehicle body 100 is large, which can effectively resist the impact force generated by the collision, reduce the risk of deformation of the front frame assembly 1, and help maintain the integrity of the front compartment frame structure 10.

[0053] Reference Figure 1 and Figure 2 As shown, the front frame assembly 1 includes an upper crossbeam 11, a lower crossbeam 12, a left pillar 13, and a right pillar 14. In the width direction of the vehicle body 100, the left pillar 13 and the right pillar 14 are arranged opposite to each other and spaced apart. The upper crossbeam 11 and the lower crossbeam 12 are both connected to the left pillar 13 and the right pillar 14. In the height direction of the vehicle body 100, the upper crossbeam 11 and the lower crossbeam 12 are arranged spaced apart, so that the front frame assembly 1 is constructed as a rectangular frame structure, which is beneficial to improving the load resistance of the front frame assembly 1.

[0054] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, the lower end of the front frame assembly 1 is also adapted to be connected to the longitudinal beam 70 of the body 100. The longitudinal beam 70 of the body 100 is adapted to reliably support the front frame assembly 1. When the front frame assembly 1 is subjected to an impact force, the impact force can be transmitted to the longitudinal beam 70 of the body 100, which has higher strength and rigidity, thus helping to reduce the risk of deformation of the front frame assembly 1.

[0055] In some embodiments of this utility model, the left connecting component 2 and the right connecting component 3 can be mirror images of each other, and the left mounting bracket 4 and the right mounting bracket 5 can be mirror images of each other, which helps to reduce the design and development cycle of the front cabin frame structure 10.

[0056] The vehicle body 100 according to another embodiment of the present invention includes the front cabin frame structure 10 of the above embodiment.

[0057] According to the vehicle body 100 implemented by this utility model, the upper left component 21 of the front cabin frame structure 10 is connected to the left side A-pillar 30, and the upper right component 31 is connected to the right side A-pillar 40. The left side A-pillar 30 and the right side A-pillar 40, which have high strength and rigidity, can reliably support the front cabin frame structure 10, thereby improving the positional accuracy of the front cabin frame structure 10 and the positional accuracy of the mounting points of the front cabin frame structure 10 for mounting parts, which is conducive to improving the installation accuracy of the parts mounted on the front cabin frame structure 10.

[0058] The vehicle according to another embodiment of the present invention includes the body 100 of the above embodiment.

[0059] According to the vehicle implemented by this utility model, the upper left component 21 of the front compartment frame structure 10 is connected to the left side A-pillar 30, and the upper right component 31 is connected to the right side A-pillar 40. The left side A-pillar 30 and the right side A-pillar 40, which have high strength and rigidity, can reliably support the front compartment frame structure 10, thereby improving the positional accuracy of the front compartment frame structure 10 and the positional accuracy of the mounting points of the front compartment frame structure 10 for mounting parts, which is conducive to improving the installation accuracy of the parts mounted on the front compartment frame structure 10.
