[0002] The trunk of a car is an important storage space in the vehicle, usually located at the rear of the vehicle, for storing luggage, shopping bags, tools and other items. With the improvement of people's living standards and the diversification of daily use needs, car owners' expectations for the trunk are also increasing. Modern car owners not only want the trunk to accommodate more items, but also want to be able to access these items more conveniently. For example, if frequently used items such as emergency kits and tool boxes are placed at the bottom of the trunk, it will be very inconvenient to take out and put these items because other items are usually placed at the bottom of the trunk. If these items are placed in the upper part of the trunk, the traditional simple trunk structure usually lacks a suitable placement point and cannot effectively fix these items.

[0052] like Figure 4 and 6 As shown, the X direction is the width direction of the vehicle body, the Y direction is the length direction of the vehicle body, and the Z direction is the height direction of the vehicle body.

[0053] See also Figure 1-4 The present invention provides a trunk assembly, including a rear door sill 1, a front cross beam 2, a side longitudinal beam 3 and a fixing mechanism 5; the rear door sill 1 is arranged on the rear body along the width direction of the body; the front cross beam 2 is arranged on the rear floor or the body structure along the width direction of the body; two side longitudinal beams 3 are arranged along the length direction of the body, and the two side longitudinal beams 3 are arranged at intervals along the width direction of the body, and the rear door sill 1, the front cross beam 2 and the two side longitudinal beams 3 are configured to be able to enclose and form a storage box body 4; the fixing mechanism 5 is arranged above or on the upper part of the storage box body 4, and is used to fix an object 10, and the fixing mechanism 5 can be adapted and installed and connected with at least the front cross beam 2 and one of the two side longitudinal beams 3.

[0054] It should be noted that a general vehicle has a rear door sill 1, which is also called a rear door sill beam or a rear lower cross beam. It is an important part of the vehicle body structure and is mainly located at the rear of the vehicle body and the trunk opening. It plays a role in strengthening the rigidity of the vehicle body and ensuring that the vehicle can maintain structural stability during driving, especially when the rear of the vehicle is subjected to external force (such as a rear collision), it can effectively absorb the impact force and protect the safety of passengers and items in the vehicle. The front cross beam 2 in the trunk of the car is a part of the vehicle body structure and is located at the front end of the trunk (close to the side of the passenger compartment in the vehicle). The front cross beam 2 is mainly used to enhance the structural rigidity of the rear of the vehicle; it connects the side longitudinal beams 3 of the trunk to form a solid frame structure, which helps to maintain the overall stability of the vehicle body during driving, especially when the vehicle is driving at high speed or a collision occurs, providing additional support and protection; in the event of a rear collision, the front cross beam 2 can help absorb and disperse part of the collision energy, reduce the impact force on the passenger compartment, and thus improve the safety performance of the vehicle. The two side longitudinal beams 3 in the trunk are located on both sides of the trunk respectively. The side longitudinal beams 3 and the front cross beam 2 together constitute the frame structure of the rear part of the vehicle body. The connection between these beams enhances the overall rigidity of the vehicle body and ensures that the vehicle has sufficient structural strength and stability during driving. The two side longitudinal beams 3 are set to form the side walls of the storage box body 4, providing structural support for the formation of the storage box body 4; at the same time, the side longitudinal beams 3 provide an installation basis for other components in the trunk. For example, in some models, the interior panels, carpets 8, partitions, and even some electrical circuits and equipment of the trunk will rely on the side longitudinal beams 3 as the basis for installation and fixing. At the same time, the side longitudinal beams 3 not only support the structure of the vehicle body, but also play a role in maintaining the shape of the vehicle body and the layout of the trunk space. It helps to maintain the shape of the trunk area, ensures the smooth appearance of the vehicle, and provides sufficient internal space for storing items. It should be noted that the front cross beam 2 and the side longitudinal beams 3 can be plastic parts with sufficient structural strength and meet the use requirements, or they can be metal parts. The rear door sill 1, the front cross beam 2, and the side longitudinal beam 3 are generally fixedly connected to the rear body, for example, firmly connected to the structural parts of the rear body. The fixing mechanism 5 can be set in one group, two groups or more groups; the fixing mechanism 5 can be a combination of one or more structures such as a guide rail mechanism, a mounting platform with positioning mounting holes, an adjustable strap mechanism, a net bag and a partition net, a detachable hook mechanism, a sliding drawer and a tray mechanism, a magnetic fixing mechanism, a vacuum suction cup fixing mechanism, and a movable partition mechanism. For example, the adjustable straps and buckles of the adjustable strap mechanism can be used to fix items, which can adapt to items of different sizes and shapes and provide a flexible fixing method; the net bag and the partition net can be used to fix small items to prevent them from moving in the trunk; these net bags can be fixed to the side longitudinal beam 3 or the front cross beam 2 by hooks and loops or buckles; the detachable hook mechanism includes a plurality of detachable and movable hooks for hanging bags or other hanging items.The hooks can be fixed on the rails and adjusted to the desired position; the sliding drawer and tray mechanism can provide additional storage space while allowing the user to easily access items; the drawers and trays can be mounted on the rails and slide freely; the magnetic fixing mechanism can be used to fix tools and other items with metal parts; the movable partition mechanism includes multiple adjustable partitions, which can adjust the storage space layout in the trunk according to the size and shape of the items, ensuring that the items are placed securely; the elastic fixing strap can be used to fix items with irregular shapes or that require a certain degree of elasticity; the vacuum suction cup fixing mechanism uses a vacuum suction cup to fix on a smooth surface, which is suitable for temporary fixation The fasteners and locking mechanisms use different types of fasteners and locking devices to firmly fix heavy or valuable items and ensure that they will not move during the driving of the vehicle. These fixing mechanisms 5 can be used alone or in combination to meet the fixing needs of items of different types and sizes, thereby increasing the diversity of the trunk storage function. In addition, since the fixing mechanisms 5 are arranged above the storage box body 4 and are used to fix objects 10, the space above the storage box body 4 in the area enclosed by the rear door sill 1, the front cross beam 2 and the two side longitudinal beams 3 can be fully utilized, thereby improving the utilization rate of the trunk space.

[0055] As an optional embodiment of this case, please refer to Figure 4-6 , 14, the fixing mechanism 5 includes a side rail assembly 51, and two side rail assemblies 51 are arranged along the length direction of the vehicle body, and the two side rail assemblies 51 are respectively arranged on the side longitudinal beam 3 and are fixedly connected and / or positionally connected to the side longitudinal beam 3.

[0056] It should be noted that the fixing mechanism 5 includes a side rail assembly 51, and two side rail assemblies 51 are arranged along the length direction of the vehicle body. The two side rail assemblies 51 are arranged in parallel, so that large objects 10 such as a storage table or a portable refrigerator or a mobile kitchen that are adapted to be connected to the side rail assemblies 51 can be installed above the two side rail assemblies 51, thereby meeting the demand for storing heavier objects 10 above the storage box body 4, thereby improving the functional diversity of the trunk assembly. If the side track assembly 51 is not provided, the object 10 can only be placed directly on the rear floor of the trunk. When the height of the object 10 is higher than the height of the rear door sill 1, it will easily fall from the rear door sill 1 to the outside of the vehicle. In this case, the upper part of the space formed by the front cross beam 2, the rear door sill 1, and the two side longitudinal beams 3 can still be used to store objects and keep the objects 10 fixed, thereby greatly improving the utilization rate of the storage space of the trunk; and ensuring the rapid installation, movement and disassembly of larger life convenience objects 10 such as portable refrigerators, mobile kitchens, or boxes with storage functions.

[0057] As an optional embodiment of this case, please refer to Figure 1-6A rear cross beam 7 arranged along the width direction of the vehicle body is provided between the front cross beam 2 and the rear door sill 1 , and the rear cross beam 7 divides the storage box body 4 into a front storage chamber 41 and a rear storage chamber 42 .

[0058] It should be noted that it should be understood that a fixed connection can be formed between the rear cross beam 7 and the two side longitudinal beams 3, thereby improving the overall stability. At the same time, the rear cross beam 7 can also be fixedly connected to the body structure and further improve the structural stability; the rear cross beam 7 divides the storage box body 4 into two independent parts, the front storage chamber 41 and the rear storage chamber 42, and the owner can classify and store the items according to their purpose, size or importance. The separated storage box body 4 limits the movement range of the items, reduces the possibility of the items colliding with each other or overturning, and improves the safety of the storage of items. The separated storage box body 4 can make more efficient use of the space in the car; at the same time, the existence of the rear cross beam 7 not only separates the storage box body 4, but also further enhances the structural rigidity of the rear part of the car body. It should be understood that the fixing mechanism 5 can be installed on the rear cross beam 7, for example, a transverse track mechanism is arranged on each of the front cross beam 2 and the rear cross beam 7, and the transverse track mechanism can be located at different heights with the side track assembly 51 in the height direction of the car body, and is designed to be a structure that does not interfere with each other, so as to more fully improve the space utilization of the trunk.

[0059] As an optional embodiment of this case, please refer to Figure 1-6 A middle longitudinal beam assembly 6 is provided between the two side longitudinal beams 3 along the length direction of the vehicle body, and the two ends of the middle longitudinal beam assembly 6 are respectively connected to the front cross beam 2 and the rear cross beam 7, and the middle longitudinal beam assembly 6 divides the front storage chamber 41 into two sub-storage chambers 411.

[0060] It should be noted that by connecting the middle longitudinal beam assembly 6 with the front cross beam 2 and the rear cross beam 7, the front storage box body 4 forms a more sophisticated frame structure, which is beneficial to the overall structural stability of the entire storage box body 4. It not only optimizes the stress distribution of the vehicle body structure and improves the overall safety of the vehicle, but also improves the flexibility and convenience of storage by subdividing the storage box body 4, allowing users to more effectively classify and manage items in the vehicle.

[0061] As an optional embodiment of this case, please refer to Figure 7 , an object 10 is mounted on the fixing mechanism 5, and the object 10 is mounted in correspondence with the fixing mechanism 5 through a mounting bracket 11;

[0062] The mounting bracket 11 is configured to enable the bottom of the object 10 and the upper portion of the storage box body 4 to form an open area of ​​a preset size.

[0063] It should be noted that the object 10 can be a portable refrigerator, a mobile kitchen with drawers, fishing gear or other supplies. The object 10 is installed by fitting with the middle track assembly 52 and / or the side track assembly 51 through the mounting bracket 11. When the fixing mechanism 5 includes the middle track assembly 52 and the side track assembly 51, that is, the lower end of the mounting bracket 11 can slide on the upper part of the middle track assembly 52 and / or the side track assembly 51; it should be understood that the mounting bracket 11 and the object 10 can be arranged in an integral manner or in a detachable manner. In this case, by setting the mounting bracket 11, the bottom of the object 10 along the height direction of the vehicle body and the upper end or upper part of the storage box body 4 form an open area of ​​a preset size, so as to facilitate the taking and placement of the object 10 in the storage box body 4. When the upper end of the storage box has a cover assembly 43, the open area should be able to ensure the opening and closing of the cover assembly 43 to meet the actual use requirements. The mounting bracket 11 may be a spiral lifting bracket or a hydraulic lifting bracket, so that the size of the open area can be adjusted according to actual needs.

[0064] As an optional embodiment of this case, please refer to Figure 4-6 8-10, the fixing mechanism 5 further includes a middle track assembly 52, and the middle track assembly 52 is installed on the middle longitudinal beam assembly 6; the middle longitudinal beam assembly 6 includes a support assembly 61 and a positioning bracket 62;

[0065] The support assembly 61 is used to be fixedly installed on the vehicle body structure along the length direction of the vehicle body; the positioning bracket 62 is arranged on the support assembly 61, and the two ends of the positioning bracket 62 are respectively used for positioning and connecting with the front cross beam 2 and the rear cross beam 7, and the side of the positioning bracket 62 away from the support assembly 61 is used to install the middle track assembly 52.

[0066] It should be noted that, since side rail assemblies 51 are provided on both sides of the trunk, the side rail assemblies 51 are positioned and installed on the side longitudinal beams 3, one end of the side longitudinal beams 3 is positioned and connected to the front cross beam 2, and the front cross beam 2 and the rear cross beam 7 are generally plastic parts. If the middle longitudinal beam assembly 6 is directly positioned and installed on the rear vehicle body, it may increase the position error when used in conjunction with the side rail assemblies 51. Based on this background, in order to reduce the positioning error of the middle rail assembly 52 and ensure that the bottom of the middle rail assembly 52 has sufficient support, a middle longitudinal beam assembly 6 is designed, and the middle longitudinal beam assembly 6 includes a support assembly 61 and a positioning bracket 62; the support assembly 61 is arranged on the rear vehicle body in the trunk along the length direction of the vehicle, and is fastened to the rear vehicle body in a detachable manner such as bolts. Along the width direction of the vehicle body, the support assembly 61 is generally arranged The support assembly 61 is located in the middle of the rear vehicle body and is connected to the cast aluminum structure of the rear vehicle body, so that the support assembly 61 can provide support for the middle track assembly 52 and ensure that the middle track assembly 52 has sufficient height to remain flush with the side track assembly 51. The support assembly 61 is generally made of metal material; along the vehicle body height direction, the positioning bracket 62 is arranged on the upper part of the support assembly 61 and is detachably connected to the support assembly 61; since the two ends of the positioning bracket 62 are respectively used for positioning and connecting with the front cross beam 2 on the rear vehicle body and the rear cross beam 7 on the rear vehicle body, the position of the positioning bracket 62 is ensured to be more accurate, thereby ensuring the accuracy of the installation position of the middle track assembly 52, avoiding or reducing the position error between the middle track assembly 52 and the side track assembly 51, which affects the coordinated use of the middle track assembly 52 and the side track assembly 51.

[0067] As an optional embodiment of this case, please refer to Figure 8-10 The support assembly 61 includes a fixed bracket 611 and a support member 612; the fixed bracket 611 includes a support plate and two legs 6111 for connecting to the rear floor or vehicle body structure; the support member 612 is arranged on the support plate and is used to connect and support the positioning bracket 62; the support member 612 is fixedly connected to the mounting bracket 11, such as a welding connection.

[0068] As an optional embodiment of this case, please refer to Figure 9-10, 18-19, both sides of the positioning bracket 62 are provided with reinforcing edges 623, and the reinforcing edges 623 are provided along the length direction of the positioning bracket 62, which can significantly enhance the rigidity, stability and bending resistance of the entire positioning bracket 2, so that the positioning bracket 62 can better maintain its shape and position when bearing part of the weight and external force from the middle track assembly 52, and reduce the deformation caused by the force; and the design of the reinforcing edges 623 allows the positioning bracket 2 to be more precise when connected to the front crossbeam 100 and the rear crossbeam 200, because they provide a more stable and accurate reference surface for installation, which helps to ensure the precise matching of the middle track assembly 52 and the side track assembly 51, and reduce the misalignment problem during use. And the reinforcing edges 623 are folded toward the inside of the positioning edge 22, that is, the reinforcing edges 623 are folded toward the middle position in the width direction of the positioning edge 22, which is not only beautiful, but also can reduce or avoid scratches on relevant personnel during installation or use.

[0069] Please refer to the figure, as an optional embodiment of this case, please refer to Figure 9-10 , 19, along the length direction of the positioning bracket 62, at least one set of limiting rib grooves 213 for installing the middle track assembly 52 is formed on the positioning bracket 62.

[0070] The design of the limiting rib groove 213 provides installation limiting for the middle track assembly 52, ensuring that the middle track assembly 52 can be accurately fixed in the predetermined position during the installation process. The limiting rib groove 213 can effectively prevent the middle track assembly 52 from shifting due to vibration or external force; at the same time, the limiting rib groove 213 also enhances the stability of the positioning bracket 62 through its structure. When the track system is bearing weight, the limiting rib groove 213 can disperse the load, reduce deformation or damage caused by concentrated force, and extend the service life of the positioning bracket 2. During the installation process of the middle track assembly 52, the installer only needs to align the middle track assembly 52 with the limiting rib groove 213 and fix it, and the installation can be completed quickly, which improves the assembly efficiency.

[0071] See also Figure 9-10 , 19, as an optional embodiment of the present case, along the width direction of the positioning bracket 62, the limiting rib grooves 213 are arranged in two groups at intervals, so as to facilitate the matching installation of two middle track components 52;

[0072] A decorative plate 624 is matched between the two groups of the limiting rib grooves 213, and the decorative plate 624 is arranged flush with the middle track assembly 52 along its own length direction and / or height direction, and the height direction is the height direction of the vehicle body when the positioning bracket 2 is connected to the front cross beam 100 and the rear cross beam 200. It should be noted that the combination of the two groups of limiting rib grooves 213 and the decorative plate 624 provides a precise installation reference for the middle track assembly 52, so that the middle track assembly 52 can be installed more accurately at the predetermined position, which helps to ensure the accurate alignment between the middle track assembly 52 and the side track assembly 51; at the same time, since the decorative plate 624 is arranged flush with the middle track assembly 52 along its own length direction and / or height direction, it is beneficial to the overall beauty of the middle track assembly 52.

[0073] See also Figure 9-10 19. As an optional embodiment of the present case, a plurality of mounting through holes 622 are evenly arranged on the positioning bracket 62, and a connecting member passing through the mounting through hole 622 and connected to the middle track assembly 52 is arranged at one end of the support member 612 facing the positioning bracket 2. The connecting member can be a bolt, a screw and / or a positioning element, thereby simplifying the assembly process and improving the assembly efficiency of the middle track assembly.

[0074] As an optional embodiment of this case, please refer to Figure 1 , 4 , 11-13, one end of the side longitudinal beam 3 is positioned and connected to the front cross beam 2; the bottom of the side longitudinal beam 3 is fixedly connected to the rear floor or the body structure, and the side of the side longitudinal beam 3 close to the body side panel is fixedly connected to the body side panel; and / or the other end of the side longitudinal beam 3 is also connected to the rear door sill 1.

[0075] It should be noted that the side longitudinal beam 3 can be reused in multiple vehicle models, that is, it can be used in both vehicle models with a fixing mechanism 5 and vehicle models without a fixing mechanism 5. One end of the side longitudinal beam 3 is positioned and connected to the front cross beam 2 through an extended support leg 31. The upper part of the extended support leg 31 is provided with a first mounting point 311 and / or a first positioning point 312 for positioning and connecting with the front cross beam 2, thereby achieving a precise positioning connection with the front cross beam 2. Since the front cross beam 2 is usually set as a plastic part with slightly weak support, the present invention enables the lower part of the extended support leg 31 to extend into the limiting hole set on the front cross beam 2 and directly connect with the rear floor edge or the vehicle body structure. The rear floor edge has good strength and rigidity, thereby providing strong support for the connection between the side longitudinal beam 3 and the front cross beam 2, solving the problem of insufficient support of the side longitudinal beam 3 in the vertical or height direction of the vehicle body. In addition, the side of the side longitudinal beam 3 close to the side panel of the vehicle body is fixedly connected to the side panel of the vehicle body through the second mounting point 32, further improving the structural rigidity of the side of the side rail assembly 51. Through the fixed connection with the side panel, the side longitudinal beam 3 can effectively transfer the inertia of the vehicle when turning to the side panel of the vehicle body, thereby improving the stability of the side rail assembly 51 in sudden situations such as vehicle turning and braking. The other end of the side longitudinal beam 3 is also connected to the rear door sill 1 through the third mounting point 33, thereby adding an additional support point at the rear of the vehicle, further improving the overall rigidity of the side rail assembly 51. Through the connection with the rear door sill 1, the shaking and deformation of the side rail assembly 51 close to the rear of the vehicle when the vehicle is driving on a bumpy road can be effectively reduced; the lower end of the side longitudinal beam 3 is provided with a supporting foot, and the side longitudinal beam 3 is fixedly connected to the rear floor through the supporting foot, thereby improving the overall stability and safety of the side rail assembly 51 and the entire trunk storage box.

[0076] As an optional embodiment of this case, please refer to Figure 1 , 411-13, one side of the two sides of the side longitudinal beam 3 along the length direction of the side longitudinal beam 3 is the first side and the other side is the second side, the first side is used to connect with the side periphery of the vehicle body, the first step surface 34 and the second step surface 35 are located on the second side of the side longitudinal beam 3, wherein the two sides are not the two ends of the side longitudinal beam 3 in the length direction, and the side longitudinal beam 3 is arranged in the trunk along the length direction of the vehicle body; the first step surface 34 is arranged along the length direction of the side longitudinal beam 3 and is used to install the side rail assembly 51 arranged along the length direction of the vehicle body, it should be understood that the first step surface 34 is provided with a positioning point and / or a limiting point and / or a connecting point that is limitedly connected to the side rail assembly 51. The side rail assembly 51 can be a mounting rail or a sliding rail. The second step surface 35 is not coplanar with the first step surface 34. Generally, the second step surface 35 is arranged below one side of the first step surface 34, that is, below the vehicle body height direction. The second step surface 35 is used to install the vehicle body side trim 81 and the carpet 8 extending thereto. The second step surface 35 can generally be arranged parallel to the first step surface 34. It should be understood that the second step surface 35 is provided with positioning points and / or limiting points and / or connecting points that are limitedly connected to the vehicle body side trim 81 and the carpet 8, for example Fig.12 The limiting structure 351 is used to limit the body side trim 81; it should be noted that the first step surface 34 and the second step surface 35 both provide a standardized installation platform that can adapt to different vehicle models. For example, the first step surface 34 can adapt to the vehicle model with the side track assembly 51 in the trunk, and the second step surface 35 can provide a stable and unified installation base point for the body side trim 81 and the carpet 8 in the vehicle model without the side track assembly 51, thereby simplifying the production and installation process, reducing the complexity and cost of multi-model development, and facilitating maintenance and replacement. The side longitudinal beam 3 is configured so that when it is installed in the trunk, at least one of the first step surface 34 or the second step surface 35 can be installed in matching with the corresponding structure. It should be understood that when the side longitudinal beam 3 is installed in the vehicle, at least one of the first step surface 34 or the second step surface 35 will be used, or the first step surface 34 is installed with a side rail assembly 51 arranged along the length direction of the vehicle body, or the second step surface 35 is installed with a vehicle body side trim panel 81 and a carpet 8 extending thereto, thereby ensuring the versatility of the side longitudinal beam 3 in different vehicle models, enabling it to be installed in combination with various vehicle body structures as needed, greatly improving production efficiency and the standardization level of parts and components.

[0077] For further information, see Figure 1 , 4 , 11-13, the side longitudinal beam 3 is positioned and / or fixedly connected to the rear cross beam 7 via the fourth mounting point 331 to improve the structural stability of the two side longitudinal beams 3.

[0078] For further information, see Figure 1 , 4 , 11-13, the first step surface 34 and the second step surface 35 are connected by a connecting side wall 341. Generally, the first step surface 34 and the second step surface 35 are vertically connected to the connecting side wall 341 at the same time.

[0079] Furthermore, a limiting structure 321 is provided at the edge of the second step surface 35, and the limiting structure 321 is used to limit the body side trim panel 81 and the carpet 8, so that when the current vehicle model does not install the side guide rail assembly 51, the connection between the side longitudinal beam 3 and the body side trim panel 81 and the carpet 8 is adapted; the limiting structure 321 is arranged on a side edge of the second step surface 35 away from the connecting side wall 341.

[0080] For further information, see Figure 1 , 4 , 11-13, the side longitudinal beam 3 has a plurality of supporting feet 38, each of the supporting feet 38 has a bottom surface that is fitted and connected to the rear floor, each of the supporting feet 38 is integrally formed with the side longitudinal beam 3, and the bottom of each of the supporting feet 38 is fixedly connected to the rear floor to improve the installation stability of the side longitudinal beam 3.

[0081] As an optional embodiment of this case, please refer to Figure 1 , 4 , 11-13, an avoidance gap 36 is provided at one end of the side longitudinal beam 3 in the extension direction of the first step surface 34, and a positioning installation surface 361 is provided at the avoidance gap 36, and the positioning installation surface 361 is used for positioning and installing the support member support component 37 of the supporting side track assembly 51.

[0082] It should be noted that the avoidance gap 36 is open toward the first side, and the first side is the side opposite to the two side longitudinal beams 3, not the back-to-back side; the avoidance gap 36 is used to avoid other structures on the vehicle, so as to achieve common use among multiple vehicle models; for example, to avoid structures such as speakers in the trunk. By setting the avoidance gap 36, it can be ensured that the side longitudinal beam 3 will not interfere with these components during installation, ensuring the convenience and reliability of installation, while improving the adaptability and flexibility of the side longitudinal beam 3. A positioning installation surface 361 is provided at the avoidance gap 36, and the positioning installation surface 361 is used to position and install the support component 37 that supports the side track component 51; the positioning installation surface 361 can be provided with connection points and positioning points connected to the support component 37, so that the support component 37 can support the bottom surface of the side track component 51 at the correct position.

[0084] The first mounting portion 222 is arranged on the support body 221, and is used to be fixedly connected to the crossbeam body 21 in a forward or reverse direction; the first positioning portion 223 is arranged at one end of the support body 221, and when the reuse support 22 is installed in a forward direction, the first positioning portion 223 is used to be positioned and connected with the middle longitudinal beam assembly 6; the second mounting portion 224 is arranged at the other end of the support body 221, and when the reuse support 22 is installed in a reverse direction, the second mounting portion 224 is used to be adapted and installed with other structures of the vehicle body.

[0085] It should be noted that since some vehicle models need to install a fixing mechanism 5 and some vehicle models do not need to install a fixing mechanism 5, in order to make the front cross beam 2 adaptable to different vehicle models, it is necessary to set a reuse support 22 on the front cross beam 2. When the reuse support 22 is installed on the cross beam body 21 in the forward direction, it can be positioned and connected with the middle longitudinal beam assembly 6. When the reuse support 22 is installed on the cross beam body 21 in the reverse direction, it can be adapted and installed with accessories in other vehicle models. The first mounting portion 222 is arranged on both sides of the support body 221. For example, the first mounting portion 222 is a plate-like structure protruding from the support body 221 to both sides, so that the front and back sides of the first mounting portion 222 can be fixedly connected to the cross beam body 21; the first positioning portion 223 is arranged at one end of the support body 221 in the height direction, and the second mounting portion 224 is arranged at the other end of the support body 221, and the first positioning portion 223 and the second mounting portion 224 are arranged opposite to each other; it should be understood that a recessed structure is arranged on the cross beam body 21 to achieve adaptive installation with the reused support 22. In this case, by setting the reused support 22, the front cross beam 2 can be reused in different models, which reduces the cycle and cost of vehicle parts research and development and improves the efficiency of vehicle manufacturing.
