Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a crossbeam assembly and a vehicle. Background Technology

[0002] In existing technology, the vehicle's engine compartment is usually connected to a crossbeam. Because the crossbeam has a large span (usually greater than 30mm) in the vertical direction of the vehicle, the fasteners are prone to misalignment during the process of passing through the crossbeam and connecting to the engine compartment. This makes it difficult to pass through the crossbeam and connect to the engine compartment smoothly, which makes the installation and positioning of the crossbeam difficult. There are problems such as difficult installation operation, adjustment or hole enlargement assembly, which affects production efficiency. Utility Model Content

[0003] This application provides a crossbeam assembly and a vehicle, which aims to improve the problem of fastener misalignment, thereby ensuring the assembly position of the crossbeam body and the engine compartment and achieving efficient and accurate positioning.

[0004] A crossbeam assembly according to an embodiment of the present invention, used in a vehicle, includes: a crossbeam body, the lower wall of which has a mounting surface adapted to fit with a mounting component in the engine compartment of the vehicle, the mounting surface having a first mounting hole, and the upper wall of which has a second mounting hole opposite to the first mounting hole; a sleeve, which passes through the second mounting hole and is located above the first mounting hole; and a fastener, which includes a head and a rod portion connected to each other, the rod portion passing through the sleeve and the first mounting hole and connected to the mounting component, and the head portion being located above the sleeve.

[0005] According to the embodiment of this utility model, the crossbeam assembly has a mounting surface on the lower wall of the crossbeam body suitable for fitting with the mounting parts of the vehicle's engine compartment. The mounting surface has a first mounting hole, and the upper wall of the crossbeam body has a second mounting hole opposite to the first mounting hole. A sleeve passes through the second mounting hole and is located above the first mounting hole. The fastener includes a head and a rod that are connected to each other. The rod passes through the sleeve and the first mounting hole and is connected to the mounting parts. The head is located above the sleeve so that the sleeve guides the rod, ensuring that the fastener moves along its own axial direction. The first mounting hole limits the rod, further reducing the risk of fastener offset, ensuring the assembly position of the crossbeam body and the engine compartment, achieving efficient and accurate positioning, thereby reducing the installation interference problem between the rod and the sleeve or engine compartment caused by fastener offset, thus eliminating the problem of on-site drilling and rework, ensuring the production line's production cycle, and improving production efficiency. Meanwhile, the lower wall of the crossbeam body has an mounting surface that fits with the mounting parts in the vehicle's engine compartment, thereby increasing the mounting area between the crossbeam body and the engine compartment, further improving installation stability and enhancing the connection reliability between the crossbeam assembly and the engine compartment.

[0006] In some embodiments of this utility model, a portion of the sleeve is located above the crossbeam body, and the lower end of the sleeve abuts against the lower wall surface of the crossbeam body, ensuring that the sleeve guides the fastener between the first mounting hole and the second mounting hole, further preventing fastener misalignment and improving reliability.

[0007] In some embodiments of this invention, the surface of the fastener head facing the second mounting hole is connected to the surface of the sleeve away from the second mounting hole. This further ensures the stability and reliability of the fastener and sleeve, prevents the fastener or sleeve from shifting due to vibration or external force, and ensures that the sleeve is always stably located inside the beam body and the fastener is always stably located inside the sleeve.

[0008] In some embodiments of this utility model, the head of the fastener has a flange at one end facing the second mounting hole, and the flange is welded to the sleeve.

[0009] In some embodiments of this utility model, a gasket is provided between the flange edge and the sleeve.

[0010] In some embodiments of this invention, the diameter of the first mounting hole is smaller than the inner diameter of the sleeve. This allows the first mounting hole to limit the movement of the rod, further reducing the risk of fastener misalignment, ensuring the assembly position of the crossbeam body and the engine compartment, and further achieving efficient and precise positioning.

[0011] In some embodiments of this utility model, the mounting component has a nut on the side opposite to the crossbeam body, and the rod is adapted to be threadedly connected to the nut. By rotating the nut, the extension length of the rod can be adjusted, achieving precise control over the gap between the crossbeam body and the mounting component, ensuring a tight fit between the mounting surface of the crossbeam body and the mounting component, and further improving positioning accuracy.

[0012] In some embodiments of this utility model, there are two mounting surfaces, located at opposite ends of the crossbeam body along its length. Two first mounting holes correspond one-to-one with each mounting surface, two second mounting holes correspond one-to-one with each of the first mounting holes, two sleeves correspond one-to-one with each mounting surface, and two fasteners correspond one-to-one with each mounting surface. This allows both ends of the crossbeam body along its length to connect to the engine compartment, thereby improving the reliability of the connection between the crossbeam assembly and the engine compartment.

[0013] The vehicle according to an embodiment of the present utility model includes an engine compartment, the engine compartment having a beam assembly as described above, the beam assembly being located above the mounting member, the mounting surface being in contact with the mounting member, and the rod portion passing through the sleeve and the first mounting hole and connected to the mounting member.

[0014] According to an embodiment of this utility model, a vehicle is provided with a crossbeam assembly. The crossbeam body has a mounting surface that mates with the mounting components. The mounting surface has a first mounting hole, and the upper wall of the crossbeam body has a second mounting hole opposite to the first mounting hole. A sleeve passes through the second mounting hole and is located above the first mounting hole. A fastener includes a head and a rod connected to each other. The rod passes through the sleeve and the first mounting hole and is connected to the mounting component. The head is located above the sleeve, so that the sleeve guides the rod, ensuring the fastener moves along its axial direction. The first mounting hole limits the rod, further reducing the risk of fastener misalignment and ensuring the assembly position of the crossbeam body and the engine compartment. This achieves efficient and precise positioning, reducing installation interference between the rod and the sleeve or engine compartment caused by fastener misalignment, thereby eliminating on-site drilling and rework issues, ensuring production line cycle time, and improving production efficiency. Simultaneously, the lower wall of the crossbeam body has a mounting surface that mates with the mounting components in the vehicle's engine compartment, increasing the installation area between the crossbeam body and the engine compartment, further improving installation stability and overall vehicle reliability.

[0015] In some embodiments of this utility model, the crossbeam assembly comprises multiple components, including a first crossbeam assembly and a second crossbeam assembly. The first and second crossbeam assemblies are arranged at intervals along the longitudinal direction of the vehicle and are connected by connectors. This allows the first crossbeam assembly, the second crossbeam assembly, and the engine compartment to form a structurally stable integral structure. Attached Figure Description

[0029] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0030] The beam assembly 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0031] like Figures 1-5 As shown, the crossbeam assembly 100 according to an embodiment of the present utility model is used in a vehicle. The crossbeam assembly 100 includes a crossbeam body 1, a sleeve 2, and fasteners 3.

[0032] The vehicle includes an engine compartment 200, which has a mounting component 4. The lower wall of the crossbeam body 1 has a mounting surface 11 adapted to fit with the mounting component 4 of the engine compartment 200. The mounting surface 11 has a first mounting hole 111. The upper wall of the crossbeam body 1 has a second mounting hole 12 opposite to the first mounting hole 111. The sleeve 2 passes through the second mounting hole 12 and is located above the first mounting hole 111. The fastener 3 includes a head 31 and a rod 32 connected to each other. The rod 32 passes through the sleeve 2 and the first mounting hole 111 and is connected to the mounting component 4. The head 31 is located above the sleeve 2.

[0033] Thus, by having the rod 32 of the fastener 3 pass through the sleeve 2 and the first mounting hole 111 and connect with the mounting component 4, the crossbeam assembly 100 is connected to the nacelle 200. Simultaneously, the sleeve 2 passes through the second mounting hole 12, guiding the rod 32 and ensuring the fastener 3 moves along its axial direction. The sleeve 2 is positioned above the first mounting hole 111, allowing the rod 32 to pass through both the sleeve 2 and the first mounting hole 111 before connecting with the mounting component 4. Since the first mounting hole 111 is located on the mounting surface 11 that mates with the mounting component 4, it can limit the movement of the rod 32, further reducing the risk of fastener 3 misalignment. This ensures the assembly position of the crossbeam body 1 and the nacelle 200, achieving efficient and precise positioning. This reduces installation interference between the rod 32 and the sleeve 2 or the nacelle 200 caused by fastener 3 misalignment, thereby eliminating on-site drilling and rework issues, ensuring production line cycle time, and improving production efficiency.

[0034] In addition, the lower wall of the crossbeam body 1 has a mounting surface 11 that fits with the mounting part 4 of the vehicle's engine compartment 200, thereby increasing the mounting area between the crossbeam body 1 and the engine compartment 200, further improving installation stability, and enhancing the connection reliability between the crossbeam assembly 100 and the engine compartment 200.

[0035] Furthermore, the sleeve 2 and the crossbeam body 1 are connected by positioning and welding through a fixture, thereby ensuring the connection strength between the two and improving the reliability of the crossbeam assembly 100.

[0036] Through experimental verification by the inventors, it has been found that during the connection process between the crossbeam assembly 100 and the engine compartment 200, the problems of on-site drilling and rework can be eliminated, reducing the rework rate from 40% in the prior art to 0%. Furthermore, during the fastener 3 insertion process, the probability of interference between the fastener and the sleeve is reduced from 80% in the prior art to 0.2%. Simultaneously, after the crossbeam assembly 100 is connected to the engine compartment 200, the assembly accuracy between the crossbeam assembly 100 and the vehicle body is effectively improved, from ±2.0mm in the prior art to ±1.2mm in this application.

[0037] According to an embodiment of the present invention, the crossbeam assembly 100 has a mounting surface 11 on the lower wall of the crossbeam body 1, which is suitable for fitting with the mounting part 4 of the vehicle's engine compartment 200. The mounting surface 11 has a first mounting hole 111. The upper wall of the crossbeam body 1 has a second mounting hole 12 opposite to the first mounting hole 111. The sleeve 2 passes through the second mounting hole 12 and is located above the first mounting hole 111. The fastener 3 includes a head 31 and a rod 32 connected to each other. The rod 32 passes through the sleeve 2 and the first mounting hole 111 and is fitted with the mounting part 4. The fastener 3 is connected to component 4, with its head 31 positioned above the sleeve 2. This allows the sleeve 2 to guide the rod 32, ensuring that the fastener 3 moves along its own axial direction. The first mounting hole 111 limits the rod 32, further reducing the risk of fastener 3 misalignment. This ensures the assembly position of the crossbeam body 1 and the engine compartment 200, achieving efficient and precise positioning. This reduces installation interference between the rod 32 and the sleeve 2 or engine compartment 200 caused by fastener 3 misalignment, thereby eliminating on-site drilling and rework issues, ensuring production line cycle time, and improving production efficiency. Simultaneously, the lower wall of the crossbeam body 1 has a mounting surface 11 that mates with the mounting component 4 of the vehicle's engine compartment 200, increasing the installation area between the crossbeam body 1 and the engine compartment 200, further improving installation stability and enhancing the connection reliability between the crossbeam assembly 100 and the engine compartment 200.

[0038] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the sleeve 2 is located above the crossbeam body 1. Along the vertical direction of the vehicle, the sleeve 2 above the crossbeam body 1 has a size of 5mm-10mm. It can be understood that since the head 31 of the fastener 3 needs to be welded to the sleeve 2 to ensure the stability and reliability of the fastener 3, the 5mm-10mm sleeve 2 above the crossbeam body 1 along the vertical direction of the vehicle effectively avoids welding slag splashing onto the mounting surface 11 after welding, thus preventing installation problems and torque attenuation caused by poor flatness and surface contour accuracy of the mounting surface 11. This improves the accuracy of the mounting surface 11 and further enhances the connection reliability between the crossbeam assembly 100 and the engine compartment 200.

[0039] It should be noted that the sleeve 2 located above the crossbeam body 1 along the vertical direction of the vehicle can be 5mm, 6mm, 7mm, 8mm, 9mm or 10mm in size.

[0040] In some embodiments of this utility model, such as Figure 5 As shown, the lower end of the sleeve 2 abuts against the lower wall surface of the crossbeam body 1. Thus, during the process of the rod 32 passing through the sleeve 2 and the first mounting hole 111 and connecting with the mounting component 4, the sleeve 2 plays a guiding role for the fastener 3 between the first mounting hole 111 and the second mounting hole 12, further preventing the fastener 3 from shifting and improving reliability.

[0041] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the surface of the head 31 of the fastener 3 facing the second mounting hole 12 is connected to the surface of the sleeve 2 away from the second mounting hole 12. This arrangement further ensures the stability and reliability of the fastener 3 and the sleeve 2, preventing the fastener 3 or the sleeve 2 from shifting due to vibration or external force, and ensuring that the sleeve 2 remains stably located inside the beam body 1 and the fastener 3 remains stably located inside the sleeve 2.

[0042] In some embodiments of this utility model, such as Figure 5 As shown, the head 31 of the fastener 3 has a flange at the end facing the second mounting hole 12, and the flange is welded to the sleeve 2. Thus, the flange increases the contact area between the head 31 of the fastener 3 and the sleeve 2, improving the connection strength between the two, and the welding process further solidifies the connection, preventing the sleeve 2 and the fastener 3 from loosening due to long-term vibration or impact.

[0043] In some embodiments of this utility model, such as Figure 5 As shown, there is a gasket 6 between the flange edge and the sleeve 2. Thus, the gasket 6 avoids direct contact between the flange edge and the sleeve 2, preventing local stress concentration that could lead to deformation or fatigue cracking. At the same time, the thickness of the gasket 6 can compensate for processing errors, ensuring a tight fit between the flange edge and the sleeve 2, while also adapting to environmental changes such as thermal expansion and contraction.

[0044] In some embodiments of this utility model, such as Figure 5 As shown, the diameter of the first mounting hole 111 is smaller than the inner diameter of the sleeve 2. It can be understood that since the rod 32 passes through the sleeve 2 and the first mounting hole 111 in sequence and then connects to the mounting component 4, this setting allows the first mounting hole 111 to limit the rod 32, further reducing the risk of fastener 3 offset, ensuring the assembly position of the crossbeam body 1 and the cabin 200, and further achieving efficient and precise positioning.

[0045] In some embodiments of this utility model, such as Figure 5As shown, the mounting component 4 has a nut 5 on the side opposite to the crossbeam body 1, and the rod portion 32 is adapted to be threadedly connected to the nut 5. Thus, the rod portion 32 passes through the sleeve 2 and the first mounting hole 111 and is threadedly connected to the nut 5, thereby connecting the rod portion 32 to the mounting component 4, and further connecting the crossbeam assembly 100 to the engine compartment 200. Simultaneously, by rotating the nut 5, the extension length of the rod portion 32 can be adjusted, achieving precise control of the gap between the crossbeam body 1 and the mounting component 4, ensuring a tight fit between the mounting surface 11 of the crossbeam body 1 and the mounting component 4, further improving positioning accuracy. Furthermore, the threaded connection between the rod portion 32 and the nut 5 is a detachable connection, facilitating disassembly and maintenance, and allowing for adaptation to wear or deformation of the crossbeam body 1 and the mounting component 4 by replacing or adjusting the nut 5.

[0046] In some embodiments of this utility model, such as Figure 5 As shown, the surface area of ​​mounting surface 11 is 400 mm². 2 -900mm 2 This arrangement further ensures the mounting area between the mounting surface 11 and the mounting component 4, increases the connection strength between the crossbeam body 1 and the engine compartment 200, and further improves reliability. It should be noted that the surface area of ​​the mounting surface 11 can be 400 mm². 2 500mm 2 600mm 2 700mm 2 800mm 2 Or 900mm 2 .

[0047] In some embodiments, such as Figure 5 As shown, the mounting surface 11 has a dimension of 20mm-30mm along the left-right direction of the vehicle and a dimension of 20mm-30mm along the front-rear direction of the vehicle. This arrangement further ensures the mounting area between the mounting surface 11 and the mounting component 4, increases the connection strength between the crossbeam body 1 and the engine compartment 200, and further improves reliability.

[0048] In some embodiments of this utility model, such as Figure 3 As shown, there are two mounting surfaces 11, located at both ends of the crossbeam body 1 along its length. Two first mounting holes 111 correspond one-to-one with each mounting surface 11, two second mounting holes 12 correspond one-to-one with each first mounting hole 111, two sleeves 2 correspond one-to-one with each mounting surface 11, and two fasteners 3 correspond one-to-one with each mounting surface 11. This arrangement allows the rods 32 of the two fasteners 3 to pass through the corresponding sleeves 2 and the corresponding first mounting holes 111, respectively, and connect to the mounting components 4. This enables both ends of the crossbeam body 1 along its length to connect to the engine compartment 200, thereby improving the reliability of the connection between the crossbeam assembly 100 and the engine compartment 200.

[0049] In some embodiments of this utility model, such as Figure 5 As shown, the outer diameter of the rod 32 is 'a', and the diameter of the first mounting hole 111 is 'b', satisfying the condition: 0.2mm ≤ ba ≤ 0.5mm. Therefore, by limiting the difference between the diameter of the first mounting hole 111 and the outer diameter of the rod 32, the limiting effect of the first mounting hole 111 on the rod 32 is further ensured, effectively reducing the risk of fastener 3 offset, ensuring the assembly position of the crossbeam body 1 and the cabin 200, and further achieving efficient and precise positioning. It should be noted that the radial direction of the rod 32 is the radial direction of a circle centered at the center of the rod 32.

[0050] Optionally, the difference between the diameter of the first mounting hole 111 and the outer diameter of the rod 32 can be 0.2 mm, 0.3 mm, 0.4 mm or 0.5 mm.

[0051] In one specific embodiment, the outer diameter of the rod 32 is 10 mm, and the diameter of the first mounting hole 111 is 10.4 mm.

[0052] In some embodiments of this utility model, such as Figure 5 As shown, the outer diameter of the rod 32 is *a*, and the inner diameter of the sleeve 2 is *c*, satisfying the condition: 2mm ≤ *ca* ≤ 2.5mm. Therefore, by limiting the difference between the inner diameter of the sleeve 2 and the outer diameter of the rod 32, the guiding function of the sleeve 2 on the rod 32 is ensured, while also guaranteeing that the rod 32 can smoothly pass through the sleeve 2, thus improving overall reliability. Simultaneously, the difference between the inner diameter of the sleeve 2 and the outer diameter of the rod 32 can also absorb tolerances during the assembly process, reducing assembly difficulty and ensuring production line cycle time.

[0053] Optionally, the difference between the inner diameter of the sleeve 2 and the outer diameter of the rod 32 can be 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm or 2.5 mm.

[0054] In some embodiments of this utility model, such as Figure 5 As shown, the outer diameter of the sleeve 2 is d, and the diameter of the second mounting hole 12 is e, satisfying: 0.1mm≤ed≤0.25mm. Therefore, by limiting the difference between the diameter of the second mounting hole 12 and the outer diameter of the sleeve 2, the limiting effect of the second mounting hole 12 on the sleeve 2 is further ensured, thereby reducing the risk of fastener 3 misalignment, ensuring the assembly position of the beam body 1 and the cabin 200, and further achieving efficient and precise positioning.

[0055] The vehicle according to an embodiment of the present invention is described below.

[0056] like Figures 1-5As shown, the vehicle according to the present utility model embodiment includes an engine compartment 200 and a crossbeam assembly 100. The engine compartment 200 has a mounting member 4. The crossbeam assembly 100 is located above the mounting member 4. The mounting surface 11 is in contact with the mounting member 4. The rod portion 32 passes through the sleeve 2 and the first mounting hole 111 and is connected to the mounting member 4.

[0057] Thus, by having the rod 32 of the fastener 3 pass through the sleeve 2 and the first mounting hole 111 and connect with the mounting component 4, the crossbeam assembly 100 is connected to the nacelle 200. Simultaneously, the sleeve 2 passes through the second mounting hole 12, guiding the rod 32 and ensuring the fastener 3 moves along its axial direction. The sleeve 2 is positioned above the first mounting hole 111, allowing the rod 32 to pass through both the sleeve 2 and the first mounting hole 111 before connecting with the mounting component 4. Since the first mounting hole 111 is located on the mounting surface 11 that mates with the mounting component 4, it can limit the movement of the rod 32, further reducing the risk of fastener 3 misalignment. This ensures the assembly position of the crossbeam body 1 and the nacelle 200, achieving efficient and precise positioning. This reduces installation interference between the rod 32 and the sleeve 2 or the nacelle 200 caused by fastener 3 misalignment, thereby eliminating on-site drilling and rework issues, ensuring production line cycle time, and improving production efficiency. In addition, the lower wall of the crossbeam body 1 has a mounting surface 11 that fits with the mounting part 4 of the vehicle's engine compartment 200, thereby increasing the mounting area between the crossbeam body 1 and the engine compartment 200, further improving installation stability, and enhancing the connection reliability between the crossbeam assembly 100 and the engine compartment 200.

[0058] According to the vehicle of this utility model embodiment, a crossbeam assembly 100 is provided, which is fitted with a mounting surface 11 of the mounting member 4 of the crossbeam body 1. The mounting surface 11 has a first mounting hole 111, and the upper wall of the crossbeam body 1 has a second mounting hole 12 opposite to the first mounting hole 111. A sleeve 2 passes through the second mounting hole 12 and is located above the first mounting hole 111. The fastener 3 includes a head 31 and a rod 32 connected to each other. The rod 32 passes through the sleeve 2 and the first mounting hole 111 and is connected to the mounting member 4. Part 31 is located above sleeve 2, so that sleeve 2 guides rod 32, ensuring that fastener 3 moves along its own axial direction. It also limits rod 32 through the first mounting hole 111, further reducing the risk of fastener 3 misalignment. This ensures the assembly position of crossbeam body 1 and engine compartment 200, achieving efficient and precise positioning. This reduces installation interference between rod 32 and sleeve 2 or engine compartment 200 caused by fastener 3 misalignment, thereby eliminating on-site drilling and rework issues, ensuring production line cycle time, and improving production efficiency. Simultaneously, the lower wall of crossbeam body 1 has a mounting surface 11 that fits with the mounting parts 4 of the vehicle's engine compartment 200, increasing the installation area between crossbeam body 1 and engine compartment 200, further improving installation stability and overall vehicle reliability.

[0059] In some embodiments of this utility model, such as Figures 1-3 As shown, there are multiple crossbeam assemblies 100, including a first crossbeam assembly and a second crossbeam assembly. The first crossbeam assembly and the second crossbeam assembly are arranged at intervals along the front-rear direction of the vehicle, and the first crossbeam assembly and the second crossbeam assembly are connected by a connector 300.

[0060] It is understood that the cabin 200 has mounting parts 4 that fit with the mounting surfaces 11 of the first crossbeam assembly and the second crossbeam assembly. The first crossbeam assembly is connected to the cabin 200 by passing through the sleeve 2 and the first mounting hole 111 and connecting with the mounting parts 4. The second crossbeam assembly is connected to the cabin 200 by passing through the sleeve 2 and the first mounting hole 111 and connecting with the mounting parts 4. At the same time, the first crossbeam assembly and the second crossbeam assembly are connected by the connector 300, so that the first crossbeam assembly, the second crossbeam assembly and the cabin 200 form a structurally stable whole structure.

[0061] Furthermore, such as Figure 3 As shown, both the first and second crossbeam assemblies have two mounting surfaces 11, which are located at both ends along the length of the crossbeam body 1. The first mounting holes 111 are two corresponding to the mounting surfaces 11, the second mounting holes 12 are two corresponding to the first mounting holes 111, the sleeves 2 are two corresponding to the mounting surfaces 11, and the fasteners 3 are two corresponding to the mounting surfaces 11.

[0062] Therefore, the mounting surface 11 can increase the mounting area between the first crossbeam assembly and the engine compartment 200, as well as between the second crossbeam assembly and the engine compartment 200, thereby further improving installation stability and enhancing the connection reliability between the crossbeam assembly 100 and the engine compartment 200.

[0063] During the assembly process, the rods 32 of the two fasteners 3 of the first crossbeam assembly are first inserted into the corresponding sleeves 2 and the corresponding first mounting holes 111 and connected to the mounting parts 4, so that the two ends of the first crossbeam assembly in the length direction are connected to the engine compartment 200 respectively. Then, the rods 32 of the two fasteners 3 of the first crossbeam assembly are first inserted into the corresponding sleeves 2 and the corresponding first mounting holes 111 and connected to the mounting parts 4, so that the two ends of the second crossbeam assembly in the length direction are connected to the engine compartment 200 respectively, so that the first crossbeam assembly, the second crossbeam assembly and the engine compartment 200 form a structurally stable integral structure.

[0064] In some embodiments, such as Figure 3 and 5 As shown, the heads 31 of the two fasteners 3 of the first crossbeam assembly have flanges at the ends facing the second mounting holes 12. The flanges are welded to the sleeves 2, and a gasket 6 is provided between the flanges and the sleeves 2. This increases the contact area between the heads 31 of the fasteners 3 and the sleeves 2 by expanding the flanges, thereby improving the connection strength. Furthermore, the welding process further solidifies the connection, preventing the sleeves 2 and fasteners 3 from loosening due to long-term vibration or impact, and improving the reliability of the connection between the first crossbeam assembly and the engine compartment 200.

[0065] like Figure 3 and 5 As shown, the heads 31 of the two fasteners 3 of the second crossbeam assembly have flanges at the ends facing the second mounting holes 12. The flanges are welded to the sleeves 2, and a gasket 6 is provided between the flanges and the sleeves 2. This increases the contact area between the heads 31 of the fasteners 3 and the sleeves 2 by expanding the flanges, thereby improving the connection strength. Furthermore, the welding process further solidifies the connection, preventing the sleeves 2 and fasteners 3 from loosening due to long-term vibration or impact, and improving the reliability of the connection between the second crossbeam assembly and the engine compartment 200.

[0066] Meanwhile, by setting a gasket 6 between the flange edge and the sleeve 2, the gasket 6 avoids direct contact between the flange edge and the sleeve 2, preventing local stress concentration that could lead to deformation or fatigue cracking. At the same time, the thickness of the gasket 6 can compensate for processing errors, ensuring a tight fit between the flange edge and the sleeve 2, while also adapting to environmental changes such as thermal expansion and contraction. This reduces the installation difficulty of the first crossbeam assembly and the engine compartment 200, as well as the second crossbeam assembly and the engine compartment 200, thereby improving the vehicle assembly efficiency.

[0067] Other components of the vehicle according to the embodiments of the present invention, such as the vehicle itself and the engine compartment 200, are known to those skilled in the art and will not be described in detail here.

[0068] In this application, and in the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0069] In this application, unless otherwise expressly defined, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0070] The terms “first,” “second,” “third,” “fourth,” etc., in this application (if present) are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0071] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0072] Unless otherwise specified, all steps in this application may be performed sequentially or randomly. For example, if the method includes steps A and B, it means that the method may include steps A and B performed sequentially, or it may include steps B and A performed sequentially. For example, if the method may also include step C, it means that step C may be added to the method in any order. For example, the method may include steps A, B, and C, or it may include steps A, C, and B, or it may include steps C, A, and B, etc.

[0073] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
