[0002] In related technologies, the span between the two crossbeams at the front of the frame is large, and the distance between the front suspension mounting center point and the lower surface of the longitudinal beam is high.

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0043] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] like Figure 1 , Figure 2 and Figure 4 As shown, the frame assembly 100 according to an embodiment of the present utility model includes: a longitudinal beam 1 and a long longitudinal tie rod mounting bracket 3. The long longitudinal tie rod mounting bracket 3 is mounted on the longitudinal beam 1, and the long longitudinal tie rod mounting bracket 3 includes: a crossbeam connecting bracket 31, a reinforcing component, and a long longitudinal bracket 32.

[0045] The crossbeam connecting bracket 31 is connected below the longitudinal beam 1 and forms a crossbeam mounting cavity 301. Part of the third crossbeam 23 can extend into the crossbeam mounting cavity 301 and connect with the crossbeam connecting bracket 31. The crossbeam mounting cavity 301 is a receiving structure for inserting and mating with the third crossbeam 23, so that after the third crossbeam 23 extends into the crossbeam mounting cavity 301, the third crossbeam 23 is connected and fixed to the crossbeam connecting bracket 31. The reinforcing component is provided in the crossbeam mounting cavity 301, and part of the reinforcing component passes through the crossbeam connecting bracket 31 and forms a connection point inside the long tie rod. After the long longitudinal tie rod is impacted, the load can be transferred to the crossbeam connecting bracket 31 and the third crossbeam 23 to avoid deformation at the installation point of the long longitudinal tie rod.

[0046] Furthermore, the long longitudinal bracket 32 ​​is connected to the outside of the crossbeam connecting bracket 31 and is connected and cooperated with the longitudinal beam 1. The long longitudinal bracket 32 ​​has a long longitudinal tie rod outer connection point 322 that is opposite to the long longitudinal tie rod inner connection point 313 in the Y direction. The long longitudinal bracket 32 ​​has a long longitudinal tie rod outer connection point 322. The long longitudinal tie rod is connected to the long longitudinal tie rod inner connection point 313 and the long longitudinal tie rod outer connection point 322. After the long longitudinal tie rod is impacted, the load can be transferred to the longitudinal beam 1 to avoid deformation at the long longitudinal tie rod installation point.

[0047] In related technologies, the span between the two crossbeams at the front of the frame is large, and the distance between the front suspension mounting center point and the lower surface of the longitudinal beam is high. The large span and long cantilever will cause the overall frame to twist more, and the bracket connected to the crossbeam and longitudinal beam 1 will have a higher ability to resist torsional deformation. This will easily lead to a sharp deterioration in fatigue at the mounting point of the long longitudinal tie rod bracket, and the problem cannot be solved by simply improving the material or increasing the thickness of the material.

[0048] Based on this, this application proposes a frame assembly 100, which improves the structural strength at the installation position of the long longitudinal tie rod by setting a reinforcing component that forms an inner connection point of the long tie rod. The long longitudinal tie rod can transfer the load to the crossbeam connecting bracket 31 and the third crossbeam 23, thus preventing the long longitudinal tie rod from deforming at the installation point after being impacted.

[0049] like Figure 3 , Figure 5 and Figure 6 As shown, according to the vehicle frame assembly 100 of this utility model embodiment, the reinforcing component includes: a connection point reinforcing plate 34 and a support tube 35. The connection point reinforcing plate 34 is disposed in the crossbeam mounting cavity 301 and connected to the crossbeam connecting bracket 31. The support tube 35 is installed on the connection point reinforcing plate 34 and the crossbeam connecting bracket 31. Part of the support tube 35 extends outward from the crossbeam mounting cavity 301 to the crossbeam connecting bracket 31 and forms a long longitudinal tie rod inner connection point 313 on the outside of the crossbeam connecting bracket 31.

[0050] In some embodiments, such as Figure 6As shown, the connection point reinforcement plate 34 is located inside the beam mounting cavity 301 and connected to the beam connecting bracket 31. The connection point reinforcement plate 34 is fixed on the beam connecting bracket 31 to improve the local strength of the beam connecting bracket 31. The support tube 35 is installed on the connection point reinforcement plate 34 and the beam connecting bracket 31. Part of the support tube 35 extends outward from the beam mounting cavity 301 to the beam connecting bracket 31 and forms an inner connection point 313 of the long longitudinal tie rod on the outside of the beam connecting bracket 31. The support tube 35 is connected to the connection point reinforcement plate 34 and the beam connecting bracket 31 to improve the structural strength at the installation position of the long longitudinal tie rod and prevent deformation at the installation position of the long longitudinal tie rod. The support tube 35 extends outward to form the inner connection point 313 of the long longitudinal tie rod. The inner connection point 313 of the long longitudinal tie rod is used to fix the long longitudinal tie rod. After being impacted, it can transfer the load to the beam connecting bracket 31 and the third beam 23, thus improving the impact resistance.

[0051] like Figure 3 , Figure 5 and Figure 6 As shown, according to the vehicle frame assembly 100 of this utility model embodiment, the crossbeam connecting bracket 31 includes: a crossbeam connecting outer plate 312, the crossbeam connecting outer plate 312 and the connecting point reinforcing plate 34 are arranged opposite to each other in the Y direction, and a support tube 35 is connected to and supported on the crossbeam connecting outer plate 312 and the connecting point reinforcing plate 34; a crossbeam connecting inner plate 311, the crossbeam connecting inner plate 311 is connected to the inner side of the crossbeam connecting outer plate 312, and together with the crossbeam connecting outer plate 312, forms a crossbeam mounting cavity 301, and the crossbeam connecting inner plate 311 and the crossbeam connecting inner plate 311 are respectively connected and cooperated with the longitudinal beam 1.

[0052] In some embodiments, such as Figure 6 As shown, a second support tube mounting hole 31221 is formed on the outer plate 312 of the crossbeam connection, and a first support tube mounting hole 3411 is formed on the connection point reinforcing plate 34. The two ends of the support tube 35 are respectively supported and connected to the second support tube mounting hole 31221 and the first support tube mounting hole 3411 to realize the connection of the support tube 35, thereby improving the structural strength at the installation position of the long longitudinal tie rod.

[0053] One end of the support tube 35 extending towards the outer plate 312 of the crossbeam connection extends out of the second support tube mounting hole 31221 to form the inner connection point 313 of the long longitudinal tie rod. The inner connection point 313 of the long longitudinal tie rod is used to connect with the long longitudinal tie rod. After the long longitudinal tie rod is impacted, the load can be transferred to the crossbeam connection bracket 31 and the third crossbeam 23 to avoid deformation of the long longitudinal tie rod at the mounting point after impact.

[0054] like Figure 2 and Figure 6As shown, both the inner plate 311 and the outer plate 312 of the crossbeam connection are connected to the longitudinal beam 1. The inner plate 311 of the crossbeam connection is connected to the inner side of the outer plate 312 of the crossbeam connection. The inner plate 311 of the crossbeam connection and the outer plate 312 of the crossbeam connection form a crossbeam mounting cavity 301. The crossbeam mounting cavity 301 serves as a receiving structure for insertion and mating with the third crossbeam 23. After the third crossbeam 23 extends into the crossbeam mounting cavity 301, the third crossbeam 23 is connected and fixed to the crossbeam connecting bracket 31.

[0055] This improves the structural strength at the installation location of the long longitudinal tie rod, and after the long longitudinal tie rod is impacted, the load can be transferred to the longitudinal beam 1 and the third crossbeam 23 through the inner plate 311 and the outer plate 312 of the crossbeam connection, thus avoiding deformation at the installation point of the long longitudinal tie rod.

[0056] like Figure 3 and Figure 6 As shown, according to the vehicle frame assembly 100 of this utility model embodiment, the long longitudinal support 32 includes: a long longitudinal support main board section 323, which is disposed opposite to the crossbeam connecting outer plate 312 in the Y direction, and the long longitudinal support main board section 323 forms the long longitudinal tie rod outer connection point 322; a long longitudinal support front plate section 324, which is connected to the front side of the long longitudinal support main board section 323 and is folded inward relative to the long longitudinal support main board section 323 to connect with the crossbeam connecting outer plate 312; and a long longitudinal support rear plate section 325, which is connected to the rear side of the long longitudinal support main board section 323 and is folded inward relative to the long longitudinal support main board section 323 to connect with the crossbeam connecting outer plate 312.

[0057] In some embodiments, such as Figure 1 and Figure 6 As shown, the upper end of the main board section 323 of the long longitudinal support is connected to the longitudinal beam 1. The front end of the main board section 323 of the long longitudinal support is connected to the front plate section 324 of the long longitudinal support. The front plate section 324 of the long longitudinal support is folded inward and connected to the outer plate 312 of the crossbeam. The rear end of the main board section 323 of the longitudinal support is connected to the rear plate section 325 of the long longitudinal support. The main board section 323 of the long longitudinal support is folded inward and connected to the outer plate 312 of the crossbeam.

[0058] This improves the structural strength at the installation location of the long longitudinal tie rod. After the long longitudinal tie rod is subjected to impact, the load can be transferred to the longitudinal beam 1, the crossbeam connecting bracket 31, and the third crossbeam 23, thus preventing deformation at the installation point of the long longitudinal tie rod.

[0059] like Figure 3 and Figure 6 As shown, in the vehicle frame assembly 100 according to the present utility model embodiment, the long longitudinal support main board section 323 is provided with a long longitudinal tie rod mounting boss. The long longitudinal tie rod mounting boss protrudes towards the side of the crossbeam connecting outer plate 312 and is arranged around the long longitudinal tie rod outer connection point 322.

[0060] In some embodiments, such as Figure 6 As shown, the main board section 323 of the long longitudinal bracket protrudes inward, that is, it protrudes towards the side of the crossbeam connecting outer plate 312, forming a long longitudinal tie rod mounting boss.

[0061] This improves the structural strength of the longitudinal support 32 and prevents it from deforming after being subjected to impact.

[0062] like Figure 5 , Figure 6 and Figure 7 As shown, according to the vehicle frame assembly 100 of this utility model embodiment, the crossbeam connecting inner plate 311 includes: a front plate section 3111 and a rear plate section 3112 of the crossbeam connecting inner plate, which are arranged opposite to each other and spaced apart in the X direction; a connection point reinforcing plate 34 is connected and cooperates with the front plate section 3111 and the rear plate section 3112 of the crossbeam connecting inner plate respectively; and a main plate section 3113 of the crossbeam connecting inner plate, which is connected between the front plate section 3111 and the rear plate section 3112 of the crossbeam connecting inner plate and cooperates with the longitudinal beam 1.

[0063] In some embodiments, such as Figure 5 , Figure 6 and Figure 7 As shown, the crossbeam connecting inner plate 311 includes a main crossbeam connecting inner plate section 3113, a front crossbeam connecting inner plate section 3111, and a rear crossbeam connecting inner plate section 3112. The upper end of the main crossbeam connecting inner plate section 3113 is connected to the longitudinal beam 1. The main crossbeam connecting inner plate section 3113 extends from the outside to the inside in the direction from top to bottom. The front end of the main crossbeam connecting inner plate section 3113 is connected to the front crossbeam connecting inner plate section 3111, and the rear end of the main crossbeam connecting inner plate section 3113 is connected to the rear crossbeam connecting inner plate section 3112. The connection point reinforcing plate 34 is connected to the front crossbeam connecting inner plate section 3111 and the rear crossbeam connecting inner plate section 3112 respectively.

[0064] This improves the connection strength between the inner plate 311 of the crossbeam connection and the reinforcing plate 34 of the connection point, thereby improving the structural strength at the installation position of the long longitudinal tie rod and preventing deformation at the installation point of the long longitudinal tie rod after it is subjected to impact.

[0065] like Figure 6 As shown, a weight-reducing hole is formed on at least one of the main plate section 3113 of the crossbeam connecting inner plate, the front plate section 3111 of the crossbeam connecting inner plate, and the rear plate section 3112 of the crossbeam connecting inner plate. There can be multiple weight-reducing holes.

[0066] Thus, by improving the connection strength between the inner plate 311 of the beam connection and the reinforcing plate 34 of the connection point, the weight of the inner plate 311 of the beam connection is achieved.

[0067] like Figure 5 , Figure 6 and Figure 7 As shown, according to the vehicle frame assembly 100 of this utility model embodiment, the connection point reinforcing plate 34 includes: a main reinforcing plate section 341, which is disposed opposite to the crossbeam connecting outer plate 312 in the Y direction and forms a first support tube mounting hole 3411, which is engaged with a support tube 35; a front reinforcing plate section 342, which is connected to the front side of the main reinforcing plate section 341 and folded outward relative to the main reinforcing plate section 341 to connect with the front section 3111 of the crossbeam connecting inner plate; and a rear reinforcing plate section 343, which is connected to the rear side of the main reinforcing plate section 341 and folded outward relative to the main reinforcing plate section 341 to connect with the rear section 3112 of the crossbeam connecting inner plate.

[0068] In some embodiments, such as Figure 5 , Figure 6 and Figure 7 As shown, a first support tube mounting hole 3411 is formed on the main plate segment 341 of the reinforcing plate. The support tube 35 supports and connects to the first support tube mounting hole 3411. The front plate segment 342 of the reinforcing plate is connected to the front plate segment 3111 of the inner plate of the crossbeam. The rear plate segment 343 of the reinforcing plate is connected to the rear plate segment 3112 of the inner plate of the crossbeam.

[0069] Therefore, the front plate segment 342 of the reinforcing plate and the front plate segment 3111 of the inner plate connecting the crossbeam form a double-layer plate structure, and the rear plate segment 343 of the reinforcing plate and the rear plate segment 3112 of the inner plate connecting the crossbeam form a double-layer plate structure. This improves the connection strength between the inner plate 311 of the crossbeam connecting plate and the reinforcing plate 34 at the connection point, thereby improving the structural strength at the installation position of the long longitudinal tie rod and preventing deformation at the installation point of the long longitudinal tie rod after it is subjected to impact.

[0070] like Figure 7 As shown, a weight-reducing hole is formed on at least one of the main plate segment 341, the front plate segment 342, and the rear plate segment 343 of the reinforcing plate. There can be multiple weight-reducing holes.

[0071] Thus, by improving the connection strength between the inner plate 311 of the beam connection and the reinforcing plate 34 of the connection point, the weight of the reinforcing plate 34 of the connection point is reduced.

[0072] like Figure 5 , Figure 6 and Figure 7As shown, according to the vehicle frame assembly 100 of this utility model embodiment, the crossbeam connecting outer plate 312 includes: a main crossbeam connecting outer plate section 3122, which is opposite to and spaced apart from the reinforcing plate main plate section 341 and has a second support tube mounting hole 31221, which is used for the support tube 35 to pass through the crossbeam mounting cavity 301; a front crossbeam connecting outer plate section 3123, which is connected to the front side of the main crossbeam connecting outer plate section 3122 and folded inward to connect with the front crossbeam connecting inner plate section 3111; and a rear crossbeam connecting outer plate section 3124, which is connected to the rear side of the main crossbeam connecting outer plate section 3122 and folded inward to connect with the rear crossbeam connecting inner plate section 3112.

[0073] In some embodiments, such as Figure 5 , Figure 6 and Figure 7 As shown, the main board section 3122 of the outer plate of the crossbeam connection is provided with a second support tube mounting hole 31221 corresponding to the first support tube mounting hole 3411. The support tube 35 supports and connects to the first support tube mounting hole 3411 and the second support tube mounting hole 31221. The front plate section 3123 of the outer plate of the crossbeam connection is connected to the front plate section 3111 of the inner plate of the crossbeam connection, and the rear plate section 3124 of the outer plate of the crossbeam connection is connected to the rear plate section 3112 of the inner plate of the crossbeam connection.

[0074] Therefore, the front plate section 3123 of the outer plate connecting the crossbeam and the front plate section 3111 of the inner plate connecting the crossbeam form a double-layer plate structure, and the rear plate section 3124 of the outer plate connecting the crossbeam and the rear plate section 3112 of the inner plate connecting the crossbeam form a double-layer plate structure, which improves the connection strength between the outer plate 312 of the crossbeam connecting the crossbeam and the inner plate 311 of the crossbeam connecting the crossbeam, thereby improving the structural strength at the installation position of the long longitudinal tie rod and preventing deformation at the installation point of the long longitudinal tie rod after it is subjected to impact.

[0075] like Figure 5 , Figure 6 and Figure 7 As shown, in the frame assembly 100 according to an embodiment of the present utility model, the crossbeam connecting outer plate 312 further includes a lower crossbeam connecting outer plate section 3125, which is connected to the bottom of the main crossbeam connecting outer plate section 3122 and folded inward; the connection point reinforcing plate 34 further includes a reinforcing plate lower plate section 344, which is connected to the bottom of the main reinforcing plate section 341 and folded outward to connect with the lower crossbeam connecting outer plate section 3125.

[0076] In some embodiments, such as Figure 5 , Figure 6 and Figure 7As shown, the lower plate segment 3125 of the outer plate of the crossbeam connection is connected to the bottom of the main plate segment 3122 of the outer plate of the crossbeam connection and is folded towards the inner plate 311 of the crossbeam connection. The lower plate segment 344 of the reinforcing plate is connected to the bottom of the main plate segment 341 of the reinforcing plate and is folded towards the outer plate 312 of the crossbeam connection. The lower plate segment 344 of the reinforcing plate is connected to the lower plate segment 3125 of the outer plate of the crossbeam connection.

[0077] Therefore, the connection between the lower plate segment 344 and the lower plate segment 3125 of the outer plate connecting the crossbeam forms a double-layer plate structure, which improves the connection strength between the outer plate 312 of the crossbeam connecting and the inner plate 311 of the crossbeam connecting, thereby improving the structural strength at the installation position of the long longitudinal tie rod and preventing deformation at the installation point of the long longitudinal tie rod after it is impacted.

[0078] like Figure 7 As shown, weight-reducing holes are formed on the lower plate section 3125 of the outer plate connecting the crossbeam, and there can be multiple weight-reducing holes.

[0079] Thus, by improving the connection strength between the inner plate 311 of the beam connection and the reinforcing plate 34 of the connection point, lightweighting is achieved.

[0080] like Figure 6 As shown, in the frame assembly 100 according to an embodiment of the present utility model, the front plate section 324 of the long longitudinal support has a long longitudinal tie rod clearance opening 326, which extends upward from the lower edge of the front plate section 324 of the long longitudinal support.

[0081] In some embodiments, such as Figure 5 , Figure 6 and Figure 7 As shown, the front plate section 324 of the long longitudinal support has a notch that opens downwards, and the long longitudinal tie rod is installed at the notch.

[0082] Thus, while ensuring the contact area and strength of the front plate section 3123 of the outer plate connected to the crossbeam, a clearance structure for the long longitudinal tie rod is formed, thereby ensuring the connection strength between the outer plate 312 of the crossbeam and the long longitudinal support 32 while allowing the long longitudinal tie rod to pass.

[0083] In some embodiments, as shown in the appendix Figure 6 and 7 As shown, the front plate segment 342 of the reinforcing plate is connected to the front plate segment 3111 of the inner plate connected to the crossbeam to form a double-layer plate structure. The rear plate segment 343 of the reinforcing plate is connected to the rear plate segment 3112 of the inner plate connected to the crossbeam to form a double-layer plate structure. The front plate segment 3123 of the outer plate connected to the crossbeam is connected to the front plate segment 3111 of the inner plate connected to the crossbeam to form a double-layer plate structure. The rear plate segment 3124 of the outer plate connected to the crossbeam is connected to the rear plate segment 3112 of the inner plate connected to the crossbeam to form a double-layer plate structure. The lower plate segment 344 of the reinforcing plate is connected to the lower plate segment 3125 of the outer plate connected to the crossbeam to form a double-layer plate structure.

[0084] Therefore, when the connection point reinforcing plate 34 is connected to the outer plate 312 of the crossbeam, a double-layer plate structure is formed. When the connection point reinforcing plate 34 is connected to the inner plate 311 of the crossbeam, a double-layer plate structure is formed. This improves the local strength and helps to improve the load-bearing performance. In turn, it can prevent deformation at the installation point of the long longitudinal tie rod after it is impacted.

[0085] In some embodiments, such as Figure 2 As shown, the third crossbeam 23 is connected to the crossbeam connecting bracket 31 via a connecting assembly. The connecting assembly includes a connecting bolt 331 and a connecting nut 332. The connecting bolt 331 passes through the corresponding portions of the crossbeam connecting bracket 31 and the third crossbeam 23, and engages with the threaded connection of the connecting nut 332 to achieve the connection and fixation between the crossbeam connecting bracket 31 and the third crossbeam 23. The connecting bolt 331 can be fixed to the crossbeam connecting bracket 31 by welding.

[0086] This improves the connection strength between the third crossbeam 23 and the crossbeam connecting bracket 31, which helps to improve the load-bearing performance. In turn, it can prevent deformation at the installation point of the long longitudinal tie rod after it is subjected to impact.

[0087] In some embodiments, such as Figure 1 As shown, the frame assembly 100 also includes a short longitudinal tie rod mounting bracket 4. The short longitudinal tie rod mounting bracket 4 is located on the front side of the crossbeam connecting bracket 31 and the long longitudinal bracket 32, and is connected to the crossbeam connecting bracket 31, the long longitudinal bracket 32 ​​and the longitudinal beam 1. The short longitudinal tie rod mounting bracket 4 forms a short longitudinal tie rod mounting cavity 401, and one end of the short longitudinal tie rod is connected to the short longitudinal tie rod mounting bracket 4.

[0088] Therefore, by connecting the short longitudinal tie rod mounting bracket 4 and the long longitudinal tie rod mounting bracket 3, the two are constructed as a whole, which improves the overall structural strength.

[0089] Understandably, the frame assembly 100 includes: a front axle, which is connected to the longitudinal beam 1 via a five-bar linkage; two sets of long longitudinal tie rod mounting brackets 3, each set of long longitudinal tie rod mounting brackets 3 being located on the longitudinal beam 1, and a third crossbeam 23 connecting the two sets of long longitudinal tie rod mounting brackets 3; two sets of short longitudinal tie rod mounting brackets 4, which are located in front of the long longitudinal tie rod mounting brackets 3, and each set of short longitudinal tie rod mounting brackets 4 being located on the longitudinal beam 1; a front lateral tie rod bracket, which is located on one longitudinal beam 1; and a linkage assembly, which includes a lateral tie rod, two long longitudinal tie rods, and two short longitudinal tie rods. Each long longitudinal tie rod is connected to the front axle and one set of long longitudinal tie rod mounting brackets 3, each short longitudinal tie rod is connected to the front axle and one set of short longitudinal tie rod mounting brackets 4, and the lateral tie rod is arranged laterally and connected to the front lateral tie rod bracket and the front axle.

[0090] Two sets of long longitudinal tie rods, two sets of short longitudinal tie rods, and a cross tie rod constitute a five-bar linkage. In this embodiment, the cross beam connecting bracket 31 and the long longitudinal bracket 32 ​​cooperate to form the long longitudinal tie rod mounting bracket 3. One end of the long longitudinal tie rod is mounted on the long longitudinal tie rod mounting bracket 3, one end of the short longitudinal tie rod is mounted on the short longitudinal tie rod mounting bracket 4, and the other ends of the long longitudinal tie rod and the short longitudinal tie rod are connected to the front axle.

[0091] The vehicle according to an embodiment of the present invention includes the frame assembly 100 described above.

[0092] Therefore, by setting the connection point reinforcement plate 34 to support and fix the support tube 35, the structural strength at the installation position of the long longitudinal tie rod is improved, and the long longitudinal tie rod can transfer the load to the crossbeam connecting bracket 31 and the third crossbeam 23, avoiding deformation at the installation point of the long longitudinal tie rod under strong impact conditions, which helps to improve the vehicle's passability.

[0093] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
