Description

Technical Field

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

[0002] With the continuous development of automotive technology, the requirements for vehicle lightweighting are becoming increasingly stringent, and the vehicle body frame is an important part affecting the lightweighting process. Therefore, this application is hereby submitted. Utility Model Content

[0003] To address the aforementioned technical problems, this application provides a vehicle body frame and vehicle that facilitates weight reduction in the rear assemblies, thereby contributing to lightweight vehicle body design.

[0004] In a first aspect, embodiments of this application provide a vehicle frame, comprising:

[0005] The rear enclosure is a one-piece non-metallic structure;

[0006] A tailgate latch mounting assembly, one end of which is connected to the rear enclosure assembly.

[0007] In the aforementioned technical solution, the integrated non-metallic structure helps reduce the number of parts and the assembly between them, which in turn helps to reduce the weight of the rear assembly and thus contributes to the lightweight design of the vehicle body. Furthermore, the seamless, one-piece structure reduces stress concentration points, improving the overall strength and rigidity of the rear assembly and enabling it to provide more stable support for the tailgate latch mounting components.

[0008] Furthermore, the process of using non-metallic structures to manufacture rear components eliminates the need for stamping, welding, and painting processes, which helps improve manufacturing efficiency and reduces the need for stamping, welding, and painting workshops, thus helping to lower vehicle manufacturing costs.

[0009] In some embodiments, the vehicle frame includes a rear bumper beam located below the rear bulkhead assembly, which is connected to the rear bumper beam via the tailgate latch mounting assembly.

[0010] In the aforementioned technical solution, under vehicle torsion conditions and during tailgate opening and closing, the loads borne by the tailgate latch and rear panel are transferred to the rear bumper beam through the tailgate latch mounting assembly. This helps reduce local deformation of the tailgate latch and rear panel components under vehicle torsion conditions and when the tailgate is closed, thus improving the torsional stiffness of the rear panel components and the local stiffness of the tailgate latch. In a rear-end collision, the rear bumper beam absorbs impact energy through its own deformation, reducing the degree of damage to the rear structure. Furthermore, the tailgate latch mounting assembly can transfer the impact load to the rear panel components and rear bumper beam, further reducing the probability of tearing at the latch mounting point.

[0011] In some implementations, the connection between the rear bumper beam and the tailgate latch mounting assembly is achieved by at least one of adhesive bonding, welding, riveting, and threaded connection. This establishes the connection between the rear bumper beam and the tailgate latch mounting assembly.

[0012] In some implementations, the projection of the rear bulkhead assembly does not overlap with the projection of the rear bumper beam when projected onto a plane perpendicular to the front-rear direction of the vehicle body.

[0013] In the above technical solution, on the one hand, interference between the rear bulkhead assembly and the rear bumper beam can be avoided as much as possible during assembly. On the other hand, when a collision occurs at the rear of the vehicle, the impact force is first concentrated on the rear bumper beam, which undergoes controllable deformation to absorb energy. A portion of the remaining collision energy is transferred to the rear bulkhead assembly through the tailgate latch mounting assembly. Since the projections of the rear bulkhead assembly and the rear bumper beam do not overlap, the rear bumper beam will not directly transfer the collision energy to the rear bulkhead assembly, which helps to reduce the collision energy borne by the rear bulkhead assembly.

[0014] In some embodiments, the vehicle frame includes a connecting structure for connecting the rear longitudinal beam to the rear bumper beam;

[0015] The rear enclosure assembly has a clearance notch, and a portion of the connecting structure extends into the clearance notch.

[0016] In the above technical solution, by forming an avoidance gap in the rear assembly, the probability of interference between the connecting structure and the rear assembly is reduced during assembly. On the other hand, it also reduces the probability that when the rear of the vehicle collides, the rear anti-collision beam will transfer the collision energy to the connecting structure, and then the connecting structure will transfer the collision energy to the rear assembly.

[0017] In some embodiments, the rear enclosure assembly includes a rear panel and a reinforcing structure, the reinforcing structure being injection molded onto the side of the rear panel facing the tailgate latch mounting assembly.

[0018] In the above technical solution, the reinforcement structure helps to increase the structural performance of the rear panel. The injection molding process allows the injection plastic of the reinforcement structure to be distributed to various areas of the rear panel on the side facing the tailgate latch mounting component. Moreover, the injection molding process makes it easy to process the reinforcement structure into various shapes according to the impact stress of the rear panel component, and to increase the thickness in certain key stress areas.

[0019] In some embodiments, the rear panel includes a multilayer continuous fiber composite material layer, which is molded to form the rear panel.

[0020] In the above technical solution, the rear panel is made of continuous fiber composite material. Continuous fiber composite material has high strength, high stiffness, and lightweight characteristics, which helps to improve the structural performance of the rear panel while reducing the weight of the rear panel components. Molding using a molding process can more accurately ensure the shape and dimensional accuracy of the rear panel, so as to ensure the mechanical properties and structural integrity of the rear panel as much as possible.

[0021] In some embodiments, the continuous fiber composite layer comprises 30 to 50 parts by weight of a thermoplastic resin matrix and 50 to 70 parts by weight of continuous fibers, wherein the sum of the weight parts of the thermoplastic resin matrix and the weight parts of the continuous fibers is 100.

[0022] In the above technical solution, by controlling the content of continuous fiber and thermoplastic resin matrix within a reasonable range, it is possible to avoid the situation of continuous fiber leakage and insufficient elongation at break caused by excessive continuous fiber content and excessive resin matrix content. It is also possible to avoid the situation of insufficient composite material strength, insufficient elongation at break or excessive water absorption caused by excessively low continuous fiber content and excessively high resin matrix content. In other words, the content of continuous fiber and thermoplastic resin matrix are in a relatively balanced state, so that the performance of the composite material is suitable for making the rear panel.

[0023] In some embodiments, the reinforcing structure comprises 40 to 50 parts by weight of a thermoplastic resin matrix and 50 to 60 parts by weight of continuous fibers, wherein the sum of the weight parts of the thermoplastic resin matrix and the weight parts of the continuous fibers is 100.

[0024] In the above technical solution, by controlling the content of thermoplastic resin matrix and continuous fiber within a reasonable range, it is possible to minimize the leakage of continuous fibers and insufficient elongation at break caused by excessively high continuous fiber content and excessively low thermoplastic resin matrix content. Conversely, it is also possible to minimize the composite material's strength, elongation at break, or excessive water absorption caused by excessively low continuous fiber content and excessively high thermoplastic resin matrix content. This achieves a relatively balanced state between the content of continuous fibers and thermoplastic resin matrix, making the composite material suitable for manufacturing reinforcing structures to strengthen the rear panel.

[0025] In some embodiments, the rear panel and / or the reinforcing structure comprises a thermoplastic resin matrix and continuous fibers;

[0026] The thermoplastic resin matrix includes at least one of polyamide and polypropylene; and / or, the continuous fiber includes glass fiber.

[0027] Among the above technical solutions, polyamide and polypropylene have high strength, are easy to mold, and have good processability and recyclability. Glass fiber has high strength and high modulus, and is relatively inexpensive, which helps to reduce manufacturing costs.

[0028] In some implementations, the connection between the tailgate latch mounting assembly and the rear enclosure assembly is achieved by at least one of adhesive bonding, riveting, or threaded connection. This realizes the connection between the tailgate latch mounting assembly and the rear enclosure assembly.

[0029] Secondly, embodiments of this application provide a vehicle, the vehicle including a chassis and a body frame as described in any embodiment of this application, the body frame being disposed on the chassis.

[0030] In the above technical solution, by adopting the vehicle body frame of the embodiment of this application, it is helpful to achieve a lightweight design of the vehicle body.

[0031] In some implementations, the vehicle body frame and the chassis together enclose to form the passenger compartment of the vehicle, the vehicle including a battery, the battery casing forming the floor of the passenger compartment.

[0032] In the above technical solutions, by integrating the battery into the floor of the passenger compartment, additional supports and connectors can be reduced, which helps to reduce the overall vehicle weight and makes more efficient use of the vehicle's interior space.

[0033] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application, it can be implemented according to the contents of the specification. In order to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0049] The following is a detailed description of this application.

[0050] With the continuous development of automotive technology, traditional steel body frames have also revealed some drawbacks, such as excessive weight, susceptibility to rust, and high carbon emissions during production. The manufacturing process of steel bodies requires stamping, welding, and painting, all of which involve significant investment in stamping, welding, and painting workshops, hindering cost reduction in automobile manufacturing. Furthermore, the weight of steel bodies makes lightweight design of the entire vehicle less effective.

[0051] In view of this, in order to overcome at least some of the defects of steel car bodies, embodiments of this application provide a car body frame.

[0052] The body frame includes the rear bulkhead assembly and the tailgate latch mounting assembly. The rear bulkhead assembly is a one-piece non-metallic structure, and one end of the tailgate latch mounting assembly is connected to the rear bulkhead assembly.

[0053] Compared to traditional steel bodies, unibody non-metallic structures help reduce the number of parts and the assembly between them, enabling weight reduction in the rear assembly and thus facilitating lightweight vehicle design. Furthermore, the seamless, one-piece structure reduces stress concentration points, improving the overall strength and rigidity of the rear assembly and providing more stable support for the tailgate latch mounting components. Moreover, the process of manufacturing the rear assembly using non-metallic structures eliminates the need for stamping, welding, and painting, improving manufacturing efficiency and reducing the need for stamping, welding, and painting workshops, thereby lowering vehicle manufacturing costs.

[0054] This application also provides a vehicle, which includes a chassis and a body frame provided in any embodiment of this application, the body frame being mounted on the chassis. The chassis provides support for the body frame.

[0055] Specifically, please refer to Figure 1 and Figure 2 This application provides a vehicle body frame, which includes a rear bulkhead assembly 1 and a tailgate latch mounting assembly 2. The rear bulkhead assembly 1 is a one-piece non-metallic structure, and one end of the tailgate latch mounting assembly 2 is connected to the rear bulkhead assembly 1.

[0056] Compared to traditional steel bodies, the unibody non-metallic structure helps reduce the number of parts and the assembly between them, which helps to reduce the weight of the rear assembly 1 and thus contributes to the lightweight design of the body. Moreover, the seamless unibody structure reduces stress concentration points and helps to improve the overall strength and rigidity of the rear assembly 1, enabling it to provide more stable support for the tailgate latch mounting assembly 2.

[0057] Moreover, the process of using non-metallic structures to manufacture rear assembly 1 eliminates the need for stamping, welding, and painting processes, which helps improve manufacturing efficiency and reduces the need for stamping, welding, and painting workshops, thus helping to lower vehicle manufacturing costs.

[0058] It should be noted that the tailgate latch mounting assembly 2 is used to install the tailgate latch, which is used to cooperate with the vehicle's tailgate to open and close the vehicle's trunk.

[0059] In some embodiments, such as Figure 4 and Figure 5 As shown, the tailgate latch mounting assembly 2 includes a mounting plate 21, which is connected to the rear enclosure assembly 1. The mounting plate 21 has a latch mounting hole for threaded connectors for mounting the tailgate latch to pass through.

[0060] In some embodiments, please refer to... Figure 4 and Figure 5The tailgate latch mounting assembly 2 also includes a fixing plate 22 and a nut plate 23. The nut plate 23 has threaded holes for providing fastening points for the threaded connectors used to mount the tailgate latch. The fixing plate 22 is connected to the mounting plate 21, and an mounting space is formed between the fixing plate 22 and the mounting plate 21. The nut plate 23 is disposed within the mounting space. That is, the nut plate 23 is fixed through mechanical engagement.

[0061] In some embodiments, the nut plate 23 is clearance-fitted with the mounting space, meaning the nut plate 23 is adjustable within the mounting space. This allows for fine-tuning of the position of the nut plate 23.

[0062] In some other embodiments, the nut plate 23 can also be interference-fitted with the mounting space, that is, after the fixing plate 22 is connected to the mounting plate 21, the position of the nut plate 23 will also be fixed.

[0063] The connection method between the fixing plate 22 and the mounting plate 21 is not limited; for example, it can be welding.

[0064] In some embodiments, please refer to Figure 2 and Figure 3 The vehicle body frame includes a rear bumper beam 3, which is located below the rear bulkhead assembly 1. The rear bulkhead assembly 1 is connected to the rear bumper beam 3 via a tailgate latch mounting assembly 2. During vehicle torsion and tailgate opening / closing, the loads borne by the tailgate latch and rear bulkhead 11 are transferred to the rear bumper beam 3 via the tailgate latch mounting assembly 2. This helps reduce local deformation of the tailgate latch and rear bulkhead assembly 1 during vehicle torsion and tailgate closing, thus improving the torsional stiffness of the rear bulkhead assembly 1 and the local stiffness of the tailgate latch. In rear-end collisions, the rear bumper beam 3 absorbs impact energy through its own deformation, reducing the extent of damage to the rear structure. Furthermore, the tailgate latch mounting assembly 2 transfers the impact load to the rear bulkhead assembly 1 and the rear bumper beam 3, further reducing the likelihood of tearing at the latch mounting point.

[0065] For example, the up and down direction is Figure 1 and Figure 3 The indicated direction includes both top-down and bottom-up directions.

[0066] In some embodiments, the connection between the rear bumper beam 3 and the tailgate latch mounting assembly 2 is achieved by at least one of adhesive bonding, welding, riveting, and threaded connection. This ensures the connection between the rear bumper beam 3 and the tailgate latch mounting assembly 2.

[0067] Understandably, the material of the rear bumper beam 3 is not limited. For example, it can be aluminum alloy, steel, plastic, etc. The specific material can be set according to the performance requirements of different vehicle models.

[0068] The material of the tailgate latch mounting component 2 is also not limited. For example, it can be aluminum alloy, composite materials, etc.

[0069] For example, in an embodiment where both the rear bumper beam 3 and the tailgate latch mounting assembly 2 are made of aluminum alloy, the rear bumper beam 3 and the tailgate latch mounting assembly 2 can be connected by welding, or they can be connected by at least one of threaded connectors and riveting.

[0070] Welding methods can include, for example, aluminum arc welding. Threaded connections can include, for example, bolts and screws. Riveting connections can include, for example, blind rivets.

[0071] In some embodiments, such as Figure 3 As shown, in the orthographic projection on a plane perpendicular to the front-rear direction of the vehicle body, the projection of the rear bumper assembly 1 does not overlap with the projection of the rear bumper beam 3. On the one hand, this minimizes interference between the rear bumper assembly 1 and the rear bumper beam 3 during assembly. On the other hand, in the event of a rear-end collision, the impact force is first concentrated on the rear bumper beam 3, which undergoes controlled deformation to absorb energy. A portion of the remaining collision energy is transferred to the rear bumper assembly 1 through the tailgate latch mounting component 2. Since the projections of the rear bumper assembly 1 and the rear bumper beam 3 do not overlap, the rear bumper beam 3 does not directly transfer the collision energy to the rear bumper assembly 1, thus helping to reduce the collision energy borne by the rear bumper assembly 1.

[0072] For example, the front-back direction is Figure 1 The indicated direction includes both front to back and back to front.

[0073] In some embodiments, please refer to Figure 2 The vehicle body frame includes a connecting structure 4 for connecting the rear longitudinal beam and the rear anti-collision beam 3; the rear bulkhead assembly 1 has an avoidance notch 111, and a portion of the connecting structure 4 extends into the avoidance notch 111. In this embodiment, by forming the avoidance notch 111 in the rear bulkhead assembly 1, the probability of interference between the connecting structure 4 and the rear bulkhead assembly 1 during assembly is reduced, and the probability that the rear anti-collision beam 3 will transfer the collision energy to the connecting structure 4 and then the connecting structure 4 will transfer the collision energy to the rear bulkhead assembly 1 after the rear anti-collision beam 3 transfers the collision energy to the connecting structure 4 in the event of a rear-end collision is also reduced.

[0074] The form of the connection structure 4 is not limited; for example, it can be an energy-absorbing box or a plate-like structure.

[0075] In some embodiments, please refer to Figure 1 and Figure 2The rear enclosure assembly 1 includes a rear panel 11 and a reinforcing structure 12. The reinforcing structure 12 is injection molded onto the side of the rear panel 11 facing the tailgate latch mounting assembly 2. The reinforcing structure 12 helps to increase the structural performance of the rear panel 11. The injection molding process allows the injection material of the reinforcing structure 12 to be distributed to various areas of the rear panel 11 facing the tailgate latch mounting assembly 2. Moreover, the injection molding process facilitates the processing of the reinforcing structure 12 into various shapes according to the impact stress of the rear enclosure assembly 1, and the increase of thickness in certain critical stress areas.

[0076] For example, a cavity is formed on the side of the rear panel 11 facing the tailgate latch mounting assembly 2, and the reinforcing structure 12 is at least partially disposed in the cavity.

[0077] Specifically, the side of the rear panel 11 away from the tailgate latch mounting assembly 2 is used to connect with the rear floor of the chassis, and the two ends of the rear panel 11 along the left and right directions of the vehicle body are used to connect with the rear ends of the side panels on the left and right sides of the vehicle body respectively. The rear panel 11, the rear floor of the chassis, and the rear ends of the side panels on the left and right sides of the vehicle body together form the vehicle's trunk.

[0078] For example, the left and right directions are Figure 1 , Figure 3 The directions indicated include both left-to-right and right-to-left directions.

[0079] The form of the reinforcing structure 12 is not limited. Exemplarily, the reinforcing structure 12 includes a plurality of reinforcing ribs, with the plurality of first reinforcing ribs arranged intersectingly; or, the plurality of first reinforcing ribs are connected end to end in a ring shape, thereby forming a mesh structure. The mesh structure can minimize stress concentration in individual reinforcing ribs, that is, it can ensure that the reinforcing structure 12 can evenly distribute the force, thereby helping to improve the overall structural strength and structural stiffness of the rear assembly 1.

[0080] In some embodiments, the rear panel 11 comprises multiple layers of continuous fiber composite material, which are molded to form the rear panel 11. That is, the rear panel 11 is made of continuous fiber composite material, which possesses high strength, high stiffness, and lightweight properties, contributing to both improved structural performance and weight reduction of the rear assembly 1. Molding can accurately ensure the shape and dimensional precision of the rear panel 11, thereby maximizing its mechanical properties and structural integrity.

[0081] For example, the continuous fiber composite layer comprises 30-50 parts by weight of thermoplastic resin matrix and 50-70 parts by weight of continuous fiber, wherein the sum of the weight parts of thermoplastic resin matrix and the weight parts of continuous fiber is 100. By controlling the content of continuous fiber and thermoplastic resin matrix within a reasonable range, it is possible to avoid situations such as excessive continuous fiber content and insufficient resin matrix content leading to continuous fiber leakage and insufficient elongation at break. It is also possible to avoid situations such as insufficient composite strength, insufficient elongation at break, or excessive water absorption due to excessively low continuous fiber content and excessively high resin matrix content. In other words, the content of continuous fiber and thermoplastic resin matrix are achieved to a relatively balanced state, making the composite material suitable for manufacturing the rear panel 11.

[0082] In some embodiments, the reinforcing structure 12 comprises 40-50 parts by weight of a thermoplastic resin matrix and 50-60 parts by weight of continuous fibers, wherein the sum of the weight parts of the thermoplastic resin matrix and the weight parts of the continuous fibers is 100. By controlling the content of the thermoplastic resin matrix and the continuous fibers within a reasonable range, it is possible to avoid situations where the continuous fiber content is too high or the thermoplastic resin matrix content is too low, resulting in continuous fiber leakage and insufficient elongation at break. It is also possible to avoid situations where the composite material has insufficient strength, insufficient elongation at break, or excessive water absorption due to excessively low continuous fiber content and excessively high thermoplastic resin matrix content. This achieves a relatively balanced state between the content of continuous fibers and the thermoplastic resin matrix, making the properties of the composite material suitable for manufacturing the reinforcing structure 12 to reinforce the rear panel 11.

[0083] In some embodiments, the rear panel 11 and / or the reinforcing structure 12 include a thermoplastic resin matrix and continuous fibers;

[0084] The thermoplastic resin matrix includes at least one of polyamide and polypropylene; and / or, the continuous fiber includes glass fiber.

[0085] In this embodiment, polyamide and polypropylene have high strength, are easy to mold, and exhibit good processability and recyclability. Glass fiber has high strength and high modulus, and is relatively inexpensive, which helps reduce manufacturing costs.

[0086] In some embodiments, the connection between the tailgate latch mounting assembly 2 and the rear enclosure assembly 1 is achieved by at least one of adhesive bonding, riveting, or threaded connection. This realizes the connection between the tailgate latch mounting assembly 2 and the rear enclosure assembly 1.

[0087] For example, the vehicle frame includes a first pop rivet that connects the mounting plate 21 and the rear bulkhead assembly 1, thereby connecting the tailgate latch mounting assembly 2 and the rear bulkhead assembly 1.

[0088] This application also provides a vehicle, which includes a chassis and a body frame provided in any embodiment of this application, the body frame being mounted on the chassis. Using the body frame of the aforementioned embodiments helps to achieve a lightweight vehicle body design.

[0089] In some embodiments, the vehicle body frame and chassis are welded together.

[0090] In other embodiments, the vehicle frame can be detachably connected to the chassis, in which case the chassis is a skateboard chassis integrating the three-electric system. This configuration achieves decoupling between the vehicle frame and the chassis, allowing the vehicle frame to be replaced as needed, shortening the development cycle and reducing costs. In other words, it increases the integration of the chassis, making it adaptable to various vehicle models.

[0091] For example, the body frame and chassis are detachably connected by fasteners.

[0092] In some embodiments, the fastener may include at least one of bolts, studs, and screws.

[0093] In some embodiments, the number of fasteners is multiple.

[0094] For example, the body frame and chassis can be detachably connected by using multiple bolts in the circumferential direction of the chassis and the body frame.

[0095] In some embodiments, the vehicle body frame and chassis together enclose the passenger compartment of the vehicle, and the vehicle includes a battery, the battery casing of which forms the floor of the passenger compartment. By integrating the battery into the floor of the passenger compartment, additional supports and connectors can be reduced, which helps to reduce the overall vehicle weight and allows for more efficient use of the vehicle's interior space.
