[0006] The first crossbeam body is arranged in a transverse direction and located below the longitudinal beam, with a clearance space formed on the rear side of the first crossbeam body.

[0007] Two sets of first crossbeam mounting brackets are respectively connected to both ends of the first crossbeam body and are used to connect and cooperate with the longitudinal beam. The first crossbeam mounting brackets can also be used to install stabilizer bars.

[0008] According to some embodiments of the present invention, the first crossbeam mounting bracket includes a first crossbeam front mounting plate and a first crossbeam rear mounting plate. The first crossbeam front mounting plate and the first crossbeam rear mounting plate are fastened together to form a longitudinal beam mounting groove that is open to the upward side and runs through the front-rear direction. Part of the longitudinal beam is placed in the longitudinal beam mounting groove and is respectively connected to the first crossbeam front mounting plate and the first crossbeam rear mounting plate.

[0009] According to some embodiments of the present invention, the first crossbeam front mounting plate and the first crossbeam rear mounting plate are arranged to form a first crossbeam mounting groove that is open to the inside. The first crossbeam body is inserted into the first crossbeam mounting groove and is connected to the first crossbeam front mounting plate and the first crossbeam rear mounting plate respectively.

[0010] According to some embodiments of the present invention, the first crossbeam body includes:

[0011] The first crossbeam connecting beam segment can be inserted and connected to the first crossbeam mounting groove;

[0012] The first crossbeam main beam segment is connected between the two first crossbeam connecting beam segments and protrudes forward relative to the first crossbeam connecting beam segments to form a stabilizer bar avoidance zone on the rear side of the first crossbeam main beam segment.

[0013] According to some embodiments of the present invention, a stabilizer mounting boss is formed on the rear wall surface of the rear mounting plate of the first crossbeam. The stabilizer mounting boss protrudes rearward to form avoidance areas on the inner and outer sides of the stabilizer mounting boss in the Y direction, and the stabilizer mounting boss is used to mount the stabilizer.

[0014] According to some embodiments of the present invention, the crossbeam assembly further includes a front trailer hitch. The front mounting plate of the first crossbeam is provided with a front mounting plate connection hole, and the rear mounting plate of the first crossbeam is provided with a rear mounting plate connection hole. The front mounting plate connection hole and the rear mounting plate connection hole are arranged opposite to each other and are used for the front trailer hitch to pass through. The portion of the front trailer hitch extending rearward from the rear mounting plate connection hole is connected to the rear mounting plate of the first crossbeam. The front trailer hitch forms a front traction structure on the front side of the first crossbeam mounting bracket.

[0015] According to some embodiments of the present invention, the first crossbeam rear mounting plate is provided with two rear mounting plate connection holes, and the two rear mounting plate connection holes are respectively provided on the inner and outer sides of the stabilizer mounting boss in the Y direction.

[0016] According to some embodiments of the present invention, the crossbeam assembly further includes a front trailer hitch mounting plate, which is connected to the front mounting plate of the first crossbeam. The front trailer hitch is sequentially disposed through the front trailer hitch mounting plate, the front mounting plate of the first crossbeam, and the rear mounting plate of the first crossbeam from front to back, and the front trailer hitch is connected and cooperated with the front trailer hitch mounting plate.

[0017] According to some embodiments of the present invention, the front trailer hook mounting plate is fitted to the front mounting plate of the first crossbeam, and the front trailer hook mounting plate is provided with a fourth opening to weld the front trailer hook mounting plate and the front mounting plate of the first crossbeam together.

[0018] Compared to existing technologies, the crossbeam assembly of this utility model has the following advantages: By setting a first crossbeam mounting bracket, which is used to connect with the longitudinal beam and also provides mounting points for the stabilizer bar and front tow hook, the crossbeam assembly and stabilizer bar of this utility model embodiment are more compact in structure and occupy less space, thus increasing the usable space of the vehicle. In addition, there is no need to set an additional mounting bracket or an additional mounting part on the longitudinal beam to install the stabilizer bar, which helps to reduce the complexity of the process. By adding a crossbeam assembly to connect with the longitudinal beam in the frame assembly, the front lateral stiffness of the longitudinal beam can be improved, thereby improving the vehicle's resistance to side impacts. The rear side of the first crossbeam body forms a clearance space, which can allow some devices (such as stabilizer bars) arranged in the frame assembly to pass through, so that the arrangement of some devices in the frame assembly and the crossbeam assembly is more compact.

[0019] Another objective of this utility model is to provide a vehicle frame assembly, including a longitudinal beam and a crossbeam assembly according to the above embodiments of this utility model, wherein a stabilizer bar is installed on the crossbeam assembly and is located below the longitudinal beam and at the rear of the crossbeam assembly.

[0020] The frame assembly according to this utility model includes a crossbeam assembly, which provides better structural strength and reduces the likelihood of deformation under external loads. Located in front of the stabilizer bar, the crossbeam assembly protects the stabilizer bar. In a frontal collision, the crossbeam assembly primarily resists and absorbs impact energy, thus reducing the likelihood of stabilizer bar damage. Pre-reserved mounting points for the stabilizer bar on the first crossbeam mounting bracket reduce manufacturing complexity and increase the compactness of the stabilizer bar and crossbeam assembly arrangement, minimizing space occupation and increasing usable vehicle space. Furthermore, the larger size of the first crossbeam mounting bracket increases the connection area between the crossbeam assembly and the longitudinal beams, thereby enhancing the connection stability between the crossbeams and the crossbeam assembly.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] The subframe is the core load-bearing structure in a vehicle chassis system, situated between the main body and the suspension / powertrain. It provides support, connection, and cushioning. The subframe includes connected longitudinal and transverse beams. The middle section of the stabilizer bar is typically supported to the vehicle body via two rubber bushings. Both ends of the stabilizer bar (directly or via connecting rods) are connected to the wheels (or suspension arms). The stabilizer bar helps to suppress excessive lateral tilting of the vehicle body when one wheel is lifted or during steering. In related technologies, the spatial arrangement of the stabilizer bar and transverse beams is scattered and not ideal, requiring further improvement.

[0039] Based on this, this application proposes a crossbeam assembly for use in a vehicle frame assembly and connected to the longitudinal beams in the vehicle frame assembly. The crossbeam assembly includes a first crossbeam body and two sets of first crossbeam mounting brackets. The first crossbeam body is arranged laterally and located below the longitudinal beams. A clearance space is formed on the rear side of the first crossbeam body. The two sets of first crossbeam mounting brackets are respectively connected to both ends of the first crossbeam body and are used to connect and cooperate with the longitudinal beams. The first crossbeam mounting brackets can also be used to install stabilizer bars.

[0040] As described above, this application provides a first crossbeam mounting bracket for connecting with the longitudinal beam and also provides mounting points for the stabilizer bar. Therefore, the crossbeam assembly and stabilizer bar of this embodiment are more compactly arranged, occupying less space, which helps increase the usable space of the vehicle. By adding a crossbeam assembly connected to the longitudinal beam in the frame assembly, the front lateral stiffness of the longitudinal beam can be improved, enhancing the vehicle's resistance to side impacts. A clearance space is formed at the rear of the first crossbeam body, allowing some components (such as stabilizer bars) arranged in the frame assembly to pass through, making the arrangement of these components and the crossbeam assembly more compact.

[0041] The following will refer to Figures 1-6 The present invention will be described in detail with reference to the embodiments.

[0042] like Figure 1 and Figure 2 As shown, the crossbeam assembly 21 according to an embodiment of the present invention is used in the frame assembly and is connected to the longitudinal beam 1 in the frame assembly. Specifically, the longitudinal beam 1 can extend generally along the X direction of the vehicle (or the front-to-back direction or longitudinal direction), and the crossbeam assembly 21 can extend generally along the Y direction of the vehicle (or the left-to-right direction or lateral direction). The crossbeam assembly 21 can be connected to the front end of the longitudinal beam 1, for example, the crossbeam assembly 21 can be riveted, welded, or bolted to the front end of the longitudinal beam 1. The front side of the portion of the crossbeam assembly 21 used to connect with the longitudinal beam 1 can be flush with the front end face of the longitudinal beam 1, or the front side of the portion of the crossbeam assembly 21 used to connect with the longitudinal beam 1 can also be located behind the front end face of the longitudinal beam 1, that is, it is only provided adjacent to the front end face of the longitudinal beam 1.

[0043] By adding a crossbeam assembly 21 to the frame assembly and connecting it to the longitudinal beam 1, the front lateral stiffness of the longitudinal beam 1 can be improved, thereby enhancing the vehicle's resistance to side impacts.

[0044] For example, the crossbeam assembly 21 can be the first crossbeam of the vehicle subframe, which refers to the crossbeam of the vehicle subframe located at the front of the vehicle.

[0045] The crossbeam assembly 21 includes a first crossbeam body 211 and two sets of first crossbeam mounting brackets 212. The first crossbeam body 211 is arranged transversely and located below the longitudinal beam 1, with a clearance space formed on the rear side of the first crossbeam body 211; the two sets of first crossbeam mounting brackets 212 are respectively connected to both ends of the first crossbeam body 211 and are used to connect and cooperate with the longitudinal beam 1, and the first crossbeam mounting brackets 212 can be used to install the stabilizer bar 30.

[0046] It should be noted that the stabilizer bar 30 is positioned low, typically below the longitudinal beam 1. The first crossbeam body 211 is arranged transversely and below the longitudinal beam 1. By mounting the stabilizer bar 30 to the first crossbeam mounting bracket 212, the compactness of the arrangement of the stabilizer bar 30 and the crossbeam assembly 21 is increased, reducing the space occupied by the stabilizer bar 30 and the crossbeam assembly 21. The stabilizer bar 30 is directly mounted on the crossbeam assembly 21, which has high structural strength. Therefore, this helps to increase the installation stability of the stabilizer bar 30 and reduce the degree of potential spatial displacement of the stabilizer bar 30.

[0047] For example, the stabilizer bar 30 may be installed on the rear side of the first crossbeam mounting bracket 212; or, the stabilizer bar 30 may be installed on the bottom surface of the first crossbeam mounting bracket 212.

[0048] Two sets of first crossbeam mounting brackets 212 are respectively connected to both ends of the first crossbeam body 211 and are used to connect and mate with the longitudinal beam 1. Exemplarily, the first crossbeam mounting brackets 212 can be welded to the first crossbeam body 211; alternatively, the first crossbeam mounting brackets 212 can be threaded, bolted, or riveted to the first crossbeam body 211; or, a portion of the first crossbeam mounting brackets 212 can be integrally formed with a portion of the first crossbeam body 211. The connection and mating between the first crossbeam mounting brackets 212 and the longitudinal beam 1 provides good connection stability between the first crossbeam mounting brackets 212 and the longitudinal beam 1.

[0049] The rear side of the first crossbeam body 211 forms a clearance space, which can allow some devices (such as stabilizer bar 30) arranged in the frame assembly to pass through, so that the arrangement of some devices in the frame assembly and the crossbeam assembly 21 is more compact.

[0050] According to the embodiment of the present invention, the crossbeam assembly 21 is provided with a first crossbeam mounting bracket 212, which is used to connect with the longitudinal beam 1 and also provides mounting points for the stabilizer bar 30 and the front tow hook 213. Therefore, the structural arrangement of the crossbeam assembly 21 and the stabilizer bar 30 in this embodiment of the present invention is more compact, occupying less space, which helps to increase the usable space of the vehicle. Furthermore, there is no need to set up an additional mounting bracket or an additional mounting part on the longitudinal beam 1 to install the stabilizer bar 30, which helps to reduce the complexity of the manufacturing process. By adding the crossbeam assembly 21 to the longitudinal beam 1 in the frame assembly, the front lateral stiffness of the longitudinal beam 1 can be improved, thereby improving the vehicle's resistance to side impacts. A clearance space is formed on the rear side of the first crossbeam body 211, which allows some devices (such as the stabilizer bar 30) arranged in the frame assembly to pass through, making the arrangement of some devices in the frame assembly and the crossbeam assembly 21 more compact.

[0051] In some embodiments of this utility model, reference can be made to Figure 1 and Figure 3 The first crossbeam mounting bracket 212 includes a first crossbeam front mounting plate 2121 and a first crossbeam rear mounting plate 2122. The first crossbeam front mounting plate 2121 and the first crossbeam rear mounting plate 2122 are fastened together to form a longitudinal beam mounting groove 2123 that is open to the upward side and runs through the front and rear direction. Part of the longitudinal beam 1 is placed in the longitudinal beam mounting groove 2123 and is connected to the first crossbeam front mounting plate 2121 and the first crossbeam rear mounting plate 2122 respectively.

[0052] For example, the front mounting plate 2121 and the rear mounting plate 2122 of the first crossbeam are fastened together in the front-to-back direction; or, the front mounting plate 2121 and the rear mounting plate 2122 of the first crossbeam are fastened together in the up-down direction.

[0053] The front mounting plate 2121 and the rear mounting plate 2122 of the first crossbeam are fastened together. For example, one side of the front mounting plate 2121 and one side of the rear mounting plate 2122 are open, with the edges of the open sides of the front and rear mounting plates facing each other and connected; or, the edge of the open side of the front mounting plate 2121 is located inside the edge of the open side of the rear mounting plate 2122 and the two are connected to each other; or, the edge of the open side of the front mounting plate 2121 is located outside the edge of the open side of the rear mounting plate 2122 and the two are connected to each other. For example, the rear open edge of the front mounting plate 2121 and the front open edge of the rear mounting plate 2122 are welded to each other.

[0054] For example, the edge of the longitudinal beam mounting groove 2123 can be connected to the longitudinal beam 1 by welding.

[0055] In the above technical solution, the front mounting plate 2121 and the rear mounting plate 2122 of the first crossbeam have good structural symmetry and can work together to transmit force, resulting in high structural strength; at the same time, the processing difficulty is also low and the machinability is good.

[0056] The front mounting plate 2121 and the rear mounting plate 2122 of the first crossbeam form a longitudinal beam mounting groove 2123. Part of the longitudinal beam 1 is placed in the longitudinal beam mounting groove 2123 and connected to the front mounting plate 2121 and the rear mounting plate 2122 of the first crossbeam respectively. In this way, the connection area between the crossbeam assembly 21 and the longitudinal beam 1 is large, and the connection strength and stability are good.

[0057] For example, one can refer to Figure 4 The first crossbeam body 211 may include second members 2115 arranged vertically opposite each other. The lower side of the first member 2114 is open and its left and right ends are through. The upper side of the second member 2115 is open and its left and right ends are through. The first member 2114 and the second member 2115 are fastened together and connected to each other. The first part and the second part are connected, for example, by welding. The first crossbeam mounting bracket 212 includes a front mounting plate 2121 and a rear mounting plate 2122 of the first crossbeam. The front mounting plate 2121 and the rear mounting plate 2122 of the first crossbeam are fastened together in the front-to-back direction.

[0058] Therefore, the first crossbeam body 211 and the first crossbeam mounting bracket 212 are relatively easy to process and have high structural strength, which can better resist impact.

[0059] In some embodiments of this utility model, reference can be made to Figure 1 and Figure 6 The front mounting plate 2121 and the rear mounting plate 2122 of the first crossbeam enclose each other to form a first crossbeam mounting groove 2124 that is open to the inside. The main body 211 of the first crossbeam is inserted into the first crossbeam mounting groove 2124 and connected to the front mounting plate 2121 and the rear mounting plate 2122 of the first crossbeam respectively.

[0060] Specifically, the first crossbeam body 211 can be welded together with the first crossbeam front mounting plate 2121 and the first crossbeam rear mounting plate 2122 to form a weld bead. The weld bead is formed at the opening of the first crossbeam mounting groove 2124 and surrounds the first crossbeam body 211. In this way, the connection area between the first crossbeam body 211 and the first crossbeam front mounting plate 2121 and the first crossbeam rear mounting plate 2122 is large, the connection reliability is high, and the first crossbeam body 211 and the first crossbeam front mounting plate 2121 and the first crossbeam rear mounting plate 2122 are not easy to separate or misalign.

[0061] In the above embodiment, the first crossbeam body 211 is inserted into the first crossbeam mounting groove 2124 and connected to the front mounting plate 2121 and the rear mounting plate 2122 of the first crossbeam respectively. In this way, the contact area can be increased by the overlapping area of ​​the insertion, so that the stress distribution is more uniform, local stress concentration is reduced, and bending stiffness is improved. The insertion fit can also avoid overall thickening and reduce weight through precise overlap length design.

[0062] In some embodiments of this utility model, reference can be made to Figure 5 The first crossbeam body 211 includes the first crossbeam connecting beam segment 2111 and the first crossbeam main beam segment 2112, which can be referred to Figure 4 The first crossbeam connecting segment 2111 can be plugged into and connected to the first crossbeam mounting groove 2124; see reference. Figure 2 The first crossbeam main beam segment 2112 is connected between the two first crossbeam connecting beam segments 2111 and protrudes forward relative to the first crossbeam connecting beam segments 2111 to form a stabilizer bar avoidance zone 2113 on the rear side of the first crossbeam main beam segment 2112.

[0063] In the above technical solution, by forming a stabilizer bar avoidance zone 2113 on the rear side of the first crossbeam main beam section 2112, the first crossbeam main body 211 will not interfere with the stabilizer bar 30. At the same time, the arrangement of the stabilizer bar 30 and the crossbeam assembly 21 is more compact and occupies less space, which is conducive to expanding the available space of the vehicle. In addition, the selection of stabilizer bar 30 is more flexible and can adapt to the installation arrangement of various types of stabilizer bar 30.

[0064] Furthermore, a stabilizer bar avoidance zone 2113 is formed on the rear side of the first crossbeam main beam segment 2112. That is, the stabilizer bar 30 is located on the rear side of the first crossbeam main beam segment 2112, thus providing protection for the stabilizer bar 301. In the front-rear direction, the portion of the stabilizer bar 30 and the first crossbeam main beam segment 2112 that are opposite each other at least partially overlaps with the projection of the first crossbeam main beam segment 2112. This further enhances the protection of the stabilizer bar 30 by the first crossbeam main body 211, reducing the likelihood of damage to the stabilizer bar 30 due to a frontal collision.

[0065] In other embodiments, the first crossbeam main beam segment 2112 is connected between two first crossbeam connecting beam segments 2111 and protrudes upward relative to the first crossbeam connecting beam segments 2111 to form a stabilizer bar avoidance area 2113 on the lower side of the first crossbeam main beam segment 2112.

[0066] In the above technical solution, by forming a stabilizer bar avoidance zone 2113 on the lower side of the first crossbeam main beam section 2112, the first crossbeam main body 211 will not interfere with the stabilizer bar 30. At the same time, the arrangement of the stabilizer bar 30 and the crossbeam assembly 21 is more compact and occupies less space, which is conducive to expanding the available space of the vehicle. In addition, the selection of stabilizer bar 30 is more flexible and can adapt to the installation arrangement of various types of stabilizer bar 30.

[0067] In other embodiments, the first crossbeam main beam segment 2112 is connected between two first crossbeam connecting beam segments 2111 and protrudes downward relative to the first crossbeam connecting beam segments 2111 to form a stabilizer bar avoidance area 2113 on the upper side of the first crossbeam main beam segment 2112.

[0068] In the above technical solution, by forming a stabilizer bar avoidance zone 2113 on the upper side of the first crossbeam main beam section 2112, the first crossbeam main body 211 will not interfere with the stabilizer bar 30. At the same time, the arrangement of the stabilizer bar 30 and the crossbeam assembly 21 is more compact and occupies less space, which is conducive to expanding the available space of the vehicle. In addition, the selection of stabilizer bar 30 is more flexible and can adapt to the installation arrangement of various types of stabilizer bar 30.

[0069] In some embodiments of this utility model, reference can be made to Figure 4 and Figure 6 The rear wall of the first crossbeam rear mounting plate 2122 has a stabilizer bar mounting boss 21222. The stabilizer bar mounting boss 21222 protrudes rearward to form avoidance areas 21223 on the inner and outer sides of the stabilizer bar mounting boss 21222 in the Y direction, and the stabilizer bar mounting boss 21222 is used to mount the stabilizer bar 30.

[0070] It should be noted that the stabilizer bar 30 is usually equipped with clamps located on both sides of the rubber bushing. These clamps serve to fix the stabilizer bar 30, restrict axial movement, and reduce the possibility of lateral displacement of the stabilizer bar 30 due to vibration or torsional forces during vehicle operation, ensuring that it always remains in its designed position. For example, when cornering, the stabilizer bar 30 is subjected to torsional force, and the clamps prevent it from sliding left or right, ensuring that the suspension on both sides is subjected to force synchronously.

[0071] In the above technical solution, by setting the stabilizer mounting boss 21222, on the one hand, it can strengthen the rear wall of the first crossbeam rear mounting plate 2122, which is conducive to improving the installation stability of the stabilizer 30; on the other hand, it can form avoidance areas 21223 on the inner and outer sides of the stabilizer mounting boss 21222 in the Y direction to avoid the clamps on the stabilizer 30 and avoid interference between the clamps and the crossbeam assembly 21.

[0072] In some embodiments of this utility model, the front tow hook 213 is disposed on the first crossbeam mounting bracket 212, and a front traction structure is formed on the front side of the first crossbeam mounting bracket 212. The front traction structure is used to provide a force point for vehicle towing, rescue or transportation, and needs to withstand longitudinal tension.

[0073] The front trailer hitch 213 is mounted on the first crossbeam mounting bracket 212, which can further improve the integration of the crossbeam assembly 21 and thus further reduce the space occupied by the crossbeam assembly 21. In addition, the first crossbeam mounting bracket 212 has a mounting surface perpendicular to the front trailer hitch 213, which simplifies the fixing method of the front trailer hitch 213, improves the connection strength between the front trailer hitch 213 and the first crossbeam mounting bracket 212, and makes it less likely for the front trailer hitch 213 and the first crossbeam mounting bracket 212 to separate.

[0074] In some embodiments of this utility model, reference can be made to Figure 6 The front mounting plate 2121 of the first crossbeam is provided with a front mounting plate connection hole 21211, and the rear mounting plate 2122 of the first crossbeam is provided with a rear mounting plate connection hole 21221. The front mounting plate connection hole 21211 and the rear mounting plate connection hole 21221 are arranged opposite to each other and are used for the front trailer hitch 213 to pass through (see reference). Figure 4 The front trailer hook 213 extends rearward from the rear mounting plate connection hole 21221 and is connected to the rear mounting plate 2122 of the first crossbeam. The front trailer hook 213 forms a front traction structure on the front side of the first crossbeam mounting bracket 212.

[0075] For example, the front trailer hook 213 and the front mounting plate 2121 of the first crossbeam are welded together to form a weld bead, which is arranged around the connection hole 21211 of the front mounting plate. The front trailer hook 213 and the rear mounting plate 2122 of the first crossbeam are welded together to form a weld bead, which is arranged around the connection hole 21221 of the rear mounting plate.

[0076] In the above technical solution, the front trailer hook 213 is connected and fixed to the rear mounting plate 2122 of the first crossbeam on the rear side. The front trailer hook 213 is located in front of the front mounting plate 2121 of the first crossbeam to form a front traction structure. The connection strength between the front trailer hook 213 and the first crossbeam mounting bracket 212 is high, and the front trailer hook 213 is not easy to detach from the first crossbeam mounting bracket 212.

[0077] In some embodiments of this utility model, reference can be made to Figure 6 The first crossbeam rear mounting plate 2122 is provided with two rear mounting plate connection holes 21221, and the two rear mounting plate connection holes 21221 are respectively located on the inner and outer sides of the stabilizer bar mounting boss 21222 in the Y direction.

[0078] In the above technical solution, the setting of the stabilizer bar mounting boss 21222 can improve the structural strength of the first crossbeam rear mounting plate 2122 at the rear mounting plate connection hole 21221, which is beneficial to make the rear mounting plate connection hole 21221 less likely to be torn and damaged.

[0079] In some embodiments of this utility model, reference can be made to Figure 1 The crossbeam assembly 21 also includes a front trailer hitch mounting plate 214, which is connected to the front mounting plate 2121 of the first crossbeam. The front trailer hitch 213 is arranged to pass through the front trailer hitch mounting plate 214, the front mounting plate 2121 of the first crossbeam and the rear mounting plate 2122 of the first crossbeam from front to back, and the front trailer hitch 213 is connected and cooperated with the front trailer hitch mounting plate 214.

[0080] For example, the front trailer hitch mounting plate 214 can be welded to the front mounting plate 2121 of the first crossbeam. Exemplarily, the front mounting plate 2121 of the first crossbeam has a positioning groove, the depth of which is less than the thickness of the front trailer hitch mounting plate 214, to facilitate quick installation of the front trailer hitch mounting plate 214 to the target position. The front trailer hitch mounting plate 214 also has a through hole, which, along with the front mounting plate connection hole 21211 and the rear mounting plate connection hole 21221, are positioned opposite each other. The front trailer hitch 213 can be welded to the front trailer hitch mounting plate 214 to form a weld bead, which extends circumferentially along the through hole.

[0081] The front tow hook 213 bears enormous tensile force during vehicle rescue, towing, or transportation. By setting the front tow hook mounting plate 214 to locally reinforce the front mounting plate 2121 of the first crossbeam, structural strength, safety, and durability are ensured, making it difficult for the front tow hook 213 to detach from the first crossbeam mounting bracket 212.

[0082] In some embodiments of this utility model, reference can be made to Figure 1 The front trailer hitch mounting plate 214 is fitted to the front mounting plate 2121 of the first crossbeam, and the front trailer hitch mounting plate 214 is provided with a fourth opening 2141. The fourth opening 2141 is used to fill the welding material to weld the front trailer hitch mounting plate 214 and the front mounting plate 2121 of the first crossbeam together, that is, by plug welding.

[0083] For example, the fourth opening 2141 may be located in the middle of the two front mounting plate connection holes 21211 to help increase the connection stability between the front trailer hitch mounting plate 214 and the first crossbeam front mounting plate 2121.

[0084] In the above technical solution, the front trailer hook mounting plate 214 fits snugly with the front mounting plate 2121 of the first crossbeam to increase the contact area, which is equivalent to increasing the local strength by increasing the thickness. By setting the fourth opening 2141, the connection area between the front trailer hook 213 and the front mounting plate 2121 of the first crossbeam is increased, so that the front mounting plate 2121 of the first crossbeam and the front trailer hook mounting plate 214 can better share the tensile stress.

[0085] The second aspect of this utility model also proposes a vehicle frame assembly.

[0086] The frame assembly according to an embodiment of the present invention includes a longitudinal beam 1 and a crossbeam assembly 21 according to a first aspect of the present invention. A stabilizer bar 30 is mounted on the crossbeam assembly 21 and is located below the longitudinal beam 1 and at the rear of the crossbeam assembly 21.

[0087] Specifically, the longitudinal beam 1 can extend along the X direction of the vehicle (or the front-to-back direction or longitudinal direction), and the crossbeam assembly 21 can extend along the Y direction of the vehicle (or the left-to-right direction or the lateral direction). The crossbeam assembly 21 can be connected to the front end of the longitudinal beam 1. For example, the crossbeam assembly 21 can be riveted, welded, or bolted to the front end of the longitudinal beam 1. The front side of the part of the crossbeam assembly 21 used to connect with the longitudinal beam 1 can be flush with the front end face of the longitudinal beam 1, or the front side of the part of the crossbeam assembly 21 used to connect with the longitudinal beam 1 can also be located behind the front end face of the longitudinal beam 1, that is, it is only set adjacent to the front end face of the longitudinal beam 1.

[0088] For example, the stabilizer bar 30 can be a disconnectable stabilizer bar.

[0089] The frame assembly includes the crossbeam assembly 21, which provides better structural strength and makes it less prone to deformation under external loads.

[0090] The stabilizer bar 30 is mounted on the crossbeam assembly 21, located below the longitudinal beam 1 and at the rear of the crossbeam assembly 21. In other words, the crossbeam assembly 21 is located in front of the stabilizer bar 30, thus providing protection for the stabilizer bar 30. In the event of a frontal collision, the crossbeam assembly 21 primarily resists and absorbs impact energy, thereby reducing the likelihood of damage to the stabilizer bar 30.

[0091] Since the first crossbeam body 211 is located below the longitudinal beam 1 and needs to protect the stabilizer bar 30, the dimensions of the first crossbeam mounting bracket 212 in the vertical direction need to be set relatively large. This allows for the pre-reservation of mounting points for the stabilizer bar 30 on the first crossbeam mounting bracket 212, eliminating the need for additional mounting brackets or additional mounting parts on the longitudinal beam 1 to install the stabilizer bar 30. This reduces process complexity and increases the compactness of the arrangement of the stabilizer bar 30 and the crossbeam assembly 21, reducing space occupation and increasing the usable space of the vehicle.

[0092] Meanwhile, the larger size of the first crossbeam mounting bracket 212 also helps to increase the connection area between the crossbeam assembly 21 and the longitudinal beam 1, thereby increasing the connection stability between the longitudinal beam 1 and the crossbeam assembly 21.

[0093] The second aspect of this utility model also proposes a vehicle.

[0094] The vehicle according to an embodiment of the present invention includes a frame assembly according to a second aspect of the present invention.

[0095] According to this embodiment of the invention, the vehicle is equipped with a first crossbeam mounting bracket 212, which connects to the longitudinal beam 1 and provides mounting points for the stabilizer bar 30 and the front tow hook 213. This results in a more compact structural arrangement of the crossbeam assembly 21 and the stabilizer bar 30, occupying less space and increasing the usable space of the vehicle. Furthermore, it eliminates the need for additional mounting brackets or mounting sections on the longitudinal beam 1 to install the stabilizer bar 30, reducing manufacturing complexity. The crossbeam assembly 21 is located in front of the stabilizer bar 30, thus protecting it. In the event of a frontal collision, the crossbeam assembly 21 primarily resists and absorbs impact energy, thereby reducing the likelihood of damage to the stabilizer bar 30.
