Description

Technical Field

[0001] This application relates to the field of battery installation technology, and more particularly to a battery installation structure and an automobile. Background Technology

[0002] In automobiles, the battery plays a crucial role in starting the vehicle and opening the doors. In extreme conditions such as collisions, the battery is essential for maintaining the normal operation of critical components like the door control system. Especially during a collision, a continuous and stable power supply from the battery is a prerequisite for ensuring the proper opening of all four doors.

[0003] In related technologies, automotive battery mounting structures typically employ cantilevered battery brackets paired with battery trays. However, due to the inherent mechanical support characteristics of the cantilever bracket, its overall structural rigidity is relatively low. During a collision, the cantilever bracket is prone to deformation from the impact, potentially leading to battery failure. Utility Model Content

[0004] In view of this, the present application provides a battery mounting structure and a car, which solves the technical problem that the existing battery mounting structure is prone to deformation due to collision, resulting in battery power loss and failure, and improves the structural strength of the battery mounting structure.

[0005] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0006] In a first aspect, embodiments of this application provide a battery mounting structure.

[0007] The battery mounting structure provided in this application includes:

[0008] A first mounting component is configured to connect to the inner panel of a longitudinal beam of the vehicle.

[0009] A second mounting member is configured to connect to the inner plate of the longitudinal beam, and the second mounting member, the first mounting member, and the inner plate of the longitudinal beam together define a first cavity; the first cavity is configured to extend along the length direction of the inner plate of the longitudinal beam, and in a direction perpendicular to the extension direction of the first cavity, the cross-sectional structure of the first cavity is a closed structure.

[0010] A battery mounting component is disposed on the side of the first mounting component and the second mounting component opposite to the inner plate of the longitudinal beam, and the battery mounting component is connected to at least one of the first mounting component and the second mounting component;

[0011] A battery, wherein the battery mounting bracket supports the bottom of the battery.

[0012] The battery mounting structure of this embodiment constructs a battery mounting base using a first mounting member and a second mounting member, which, together with the inner plate of the longitudinal beam, define a first cavity extending along the length of the inner plate of the longitudinal beam. The cross-section of the first cavity along the length of the inner plate of the longitudinal beam is a closed structure. The closed cavity structure has a larger moment of inertia compared to an open cantilever bracket, which is beneficial for improving the structural strength and deformation resistance of the battery mounting base. When the first cavity is subjected to external force, the stress can be evenly distributed along all walls of the first cavity, thereby solving the problem of excessive local stress causing deformation of the cantilever bracket, thus reducing the possibility of battery failure during a vehicle collision and ensuring normal battery operation. Therefore, this embodiment, through the first mounting member, the second mounting member, and the inner plate of the longitudinal beam, defines a first cavity, improving the deformation resistance and bending stiffness of the battery mounting base, thereby improving the battery mounting stability and helping to reduce the risk of battery detachment due to deformation of the battery mounting base.

[0013] In one possible implementation of this application, the first mounting member includes a first connecting portion and a second connecting portion connected together, and the second mounting member includes a third connecting portion and a fourth connecting portion connected together.

[0014] The first connecting portion and the third connecting portion are configured to connect to different positions of the inner plate of the longitudinal beam, and the second connecting portion and the fourth connecting portion are connected; the first connecting portion, the second connecting portion, the third connecting portion, the fourth connecting portion and the inner plate of the longitudinal beam together define the first cavity.

[0015] In one possible implementation of this application, the first end of the fourth connecting portion is connected to the third connecting portion, and the second end of the fourth connecting portion is configured to bend toward the side away from the inner plate of the longitudinal beam and extend toward the second connecting portion.

[0016] The second end of the fourth connecting part is connected to the second connecting part, and the battery mounting component is connected to the second end of the fourth connecting part.

[0017] In one possible implementation of this application, a portion of the first mounting member is bent in a first direction to form a first reinforcement, the first direction being parallel to the direction from the inner longitudinal beam plate to the outer longitudinal beam plate of the vehicle; and / or,

[0018] The second mounting part is bent in a second direction to form a second reinforcing part, and the second direction intersects with the first direction.

[0019] In one possible implementation of this application, the third mounting member is disposed on the side of the second mounting member opposite to the first mounting member, and the third mounting member is configured to connect to the outer panel of the longitudinal beam of the vehicle.

[0020] The third mounting component supports the side of the battery mounting component facing the second mounting component.

[0021] In one possible implementation of this application, the third mounting member has a first end and a second end opposite to each other, the first end being connected to the outer plate of the longitudinal beam, and the second end being bent toward one side of the battery mounting member and supporting the side of the battery mounting member facing the second mounting member.

[0022] In one possible implementation of this application, a portion of the third mounting member is bent in a first direction to form a third reinforcing portion, the first direction being parallel to the direction from the inner longitudinal beam plate to the outer longitudinal beam plate of the vehicle; and / or,

[0023] A portion of the edge of the third mounting component is also bent along a second direction to form a first flange, the second direction intersecting the first direction.

[0024] In one possible implementation of this application, the battery mounting member has a connecting platform recessed toward the side of the second mounting member, and a portion of the connecting platform is further bent toward the battery to form a connecting reinforcement, the connecting reinforcement being connected to the battery.

[0025] In one possible implementation of this application, the battery mounting member has a connecting platform recessed toward the side of the second mounting member, and a portion of the connecting platform is further bent toward the battery to form a connecting reinforcement, the connecting reinforcement being connected to the battery.

[0026] In one possible implementation of this application, the battery mounting structure further includes:

[0027] A pressing member is disposed on the side of the battery and abuts against the battery; the pressing member is connected to at least one of the first mounting member and the second mounting member.

[0028] Secondly, embodiments of this application provide a vehicle, including:

[0029] The longitudinal beam includes an inner plate and an outer plate, the outer plate and the inner plate together define a second cavity, and the cross-sectional structure of the second cavity is a closed structure in a direction perpendicular to the extension direction of the second cavity.

[0030] In the above-described battery mounting structure, both the first mounting component and the second mounting component are connected to the inner plate of the longitudinal beam, and the second mounting component, the first mounting component, and the inner plate of the longitudinal beam together define the first cavity.

[0031] This application provides a battery mounting structure and an automobile. A first mounting member and a second mounting member are installed onto the inner plate of a longitudinal beam within the automobile's engine compartment. The first and second mounting members form the battery mounting base and, together with the inner plate of the longitudinal beam, define a first cavity extending along the length of the inner plate. The first cavity has a closed cross-section along the length of the inner plate. The closed cavity structure has a larger moment of inertia compared to an open cantilever bracket, which is beneficial for improving the structural strength and deformation resistance of the battery mounting base. When the first cavity is subjected to external force, the stress can be evenly distributed along all walls of the first cavity, thereby solving the problem of excessive local stress causing deformation of the cantilever bracket. This reduces the possibility of battery failure during a collision, ensuring normal battery operation. Therefore, this embodiment, through the first mounting member, the second mounting member, and the inner plate of the longitudinal beam, enhances the deformation resistance and bending stiffness of the battery mounting base, thereby improving the battery's installation stability and helping to reduce the risk of battery detachment due to deformation of the battery mounting base.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0048] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0049] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0050] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0051] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0052] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0053] The longitudinal beams within the car's engine compartment are core load-bearing components of the vehicle's frame, serving as crucial structural elements connecting the chassis and body. They are typically made of high-strength steel through stamping and welding, possessing high bending and torsional rigidity. The longitudinal beams are arranged parallel to the vehicle's centerline on both sides, extending in the same direction as the body. The front end usually connects to the front bumper frame and energy-absorbing box, while the rear end connects to the firewall or front bulkhead of the passenger compartment. The middle section supports the engine, transmission, and other powertrain components, as well as the suspension system.

[0054] Longitudinal beams typically consist of an inner longitudinal beam plate and an outer longitudinal beam plate arranged opposite each other. The inner and outer longitudinal beam plates are assembled by welding or riveting to form a closed section, creating a high-strength beam structure. The inner longitudinal beam plate is located on the inner side of the longitudinal beam, closer to the passenger compartment, and is usually connected to the firewall; it is the main load-bearing part of the longitudinal beam. The outer longitudinal beam plate is located on the outer side of the longitudinal beam, closer to both sides of the vehicle body, and is usually adjacent to the front fender and front bumper frame.

[0055] In related technologies, the battery is located in the vehicle's engine compartment and is used to connect the starter motor and alternator. The battery is typically mounted to the vehicle's frame via a cantilever bracket. This cantilever bracket is generally a metal bracket, with one end fixed to the vehicle frame, such as a longitudinal beam in the engine compartment, and the remaining portion suspended and supporting the battery. The suspended portion of the cantilever bracket has a battery tray on which the battery is mounted.

[0056] However, because the cantilever bracket is partially suspended, the suspended portion is prone to bending and deformation when subjected to impact forces, leading to a decrease in the overall stiffness of the cantilever bracket. When the cantilever bracket deforms, the supporting stability of the battery tray is compromised, and the battery may be displaced, squeezing the cables or even detaching from the tray, causing electrical connection failure (power loss) or damage to the battery itself, thus failing to meet the power supply requirements during a collision.

[0057] Based on this, this application provides a battery mounting structure and an automobile, aiming to solve the above-mentioned technical problems of the prior art. Specifically, the battery mounting structure installs a first mounting member and a second mounting member onto the inner plate of a longitudinal beam in the automobile engine compartment. The first and second mounting members are used to construct the battery mounting base and, together with the inner plate of the longitudinal beam, define a first cavity extending along the length direction of the inner plate of the longitudinal beam. The cross-section of the first cavity along the length direction of the inner plate of the longitudinal beam is a closed structure. The closed cavity structure has a larger moment of inertia than the open cantilever bracket, which is beneficial to improving the structural strength and deformation resistance of the battery mounting base. When the first cavity is subjected to external force, the stress can be evenly distributed along the various walls of the first cavity, thereby solving the problem of easy deformation of the cantilever bracket due to excessive local stress, thus reducing the possibility of battery failure during a vehicle collision and ensuring normal battery operation.

[0058] It should be noted that the term "vehicle" in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Generally, a vehicle is equipped with wheels, a power source, and a transmission system between the wheels and the power source. The transmission system transmits the power provided by the power source to the wheels, causing the wheels to rotate and thus driving the vehicle.

[0059] In this application embodiment, the type of power source of the vehicle is not limited. For example, for fuel vehicles, the power source can refer to fuel engines such as gasoline engines and diesel engines; for electric vehicles, the power source can refer to electric motors; for hybrid vehicles, the power source can refer to engines or electric motors; for vehicles powered by other means, the power source can refer to devices that generate power.

[0060] The battery mounting structure provided in this application embodiment can be used to install batteries in the engine compartment of an automobile. Please refer to... Figure 1 and Figure 2 The battery mounting structure includes a first mounting component 100, a second mounting component 200, a battery mounting component 400, and a battery 500.

[0061] The first mounting member 100 is configured to connect to the inner longitudinal beam panel 10 of the vehicle, and the second mounting member 200 is configured to connect to the inner longitudinal beam panel 10. The second mounting member 200, the first mounting member 100, and the inner longitudinal beam panel 10 together define a first cavity 30. The first cavity 30 is configured to extend along the length direction of the inner longitudinal beam panel 10, and the cross-sectional structure of the first cavity 30 is a closed structure in a direction perpendicular to the extension direction of the first cavity 30.

[0062] The battery mounting member 400 is located on the side of the first mounting member 100 and the second mounting member 200 opposite to the inner plate 10 of the longitudinal beam, and the battery mounting member 400 is connected to at least one of the first mounting member 100 and the second mounting member 200. The battery mounting member 400 supports the bottom of the battery 500.

[0063] The first mounting member 100 and the second mounting member 200 are used to construct the mounting base of the battery 500. Both the first mounting member 100 and the second mounting member 200 are mounted on the inner plate 10 of the longitudinal beam, and together with the inner plate 10 of the longitudinal beam, they define a first cavity 30 extending along the length direction of the inner plate 10 of the longitudinal beam. The cross-section of the first cavity 30 is a closed structure in a plane perpendicular to the extension direction, that is, the cross-section of the first cavity 30 in the length direction of the inner plate 10 of the longitudinal beam is a closed structure.

[0064] Because of its closed cross-section, the first cavity 30 has a larger moment of inertia compared to an open cantilever bracket, which is beneficial for improving the structural strength and deformation resistance of the battery mounting foundation. When the first cavity 30 is subjected to external forces, the stress can be evenly distributed along all the walls of the first cavity 30, avoiding excessive local stress and thus improving the situation where the cantilever bracket is prone to deformation under stress. At the same time, during the deformation process under stress, the first cavity 30 can absorb energy through the slight deformation of its own structure. In this way, even if the walls of the first cavity 30 are locally damaged or unevenly stressed, other parts can still continue to share the stress and maintain the stability of the overall structure, thereby further mitigating the damage of external forces to the first mounting component 100 and the second mounting component 200.

[0065] Therefore, in this embodiment, the first cavity 30 formed by the first mounting component 100, the second mounting component 200 and the inner plate of the longitudinal beam 10 improves the deformation resistance and bending stiffness of the battery mounting base, thereby improving the installation stability of the battery 500 and helping to reduce the risk of the battery 500 falling off due to deformation of the battery mounting base.

[0066] The battery mounting component 400 provides a mounting position for the battery 500. Its upper surface may be provided with limiting bosses or grooves that match the shape of the battery 500 to support the bottom of the battery 500 and limit its lateral displacement. The battery mounting component 400 is connected to at least one of the first mounting component 100 and the second mounting component 200, which can evenly transfer the gravity and impact load of the battery 500 to the first cavity 30 and the inner plate 10 of the longitudinal beam, thereby avoiding stress concentration caused by single-point force of traditional cantilever brackets.

[0067] The battery 500 is placed vertically on the tray of the battery mounting component 400, and its bottom is adapted to the limiting structure of the battery mounting component 400. When the vehicle collides, the impact force is first transmitted through the battery mounting component 400 to the first mounting component 100 and the second mounting component 200, and then transmitted through the first cavity 30 with a closed section to the energy-absorbing box, firewall and other protective components installed on the longitudinal beam.

[0068] For example, one of the first mounting member 100 and the second mounting member 200 is disposed on the side of the inner plate 10 of the longitudinal beam, and the other is disposed on the top surface of the inner plate 10 of the longitudinal beam, thus forming a first cavity 30 on the side, above, or laterally above the inner plate 10 of the longitudinal beam. In some embodiments, reinforcing ribs or supports may be provided inside the first cavity 30 to further improve the resistance to deformation.

[0069] Please refer to some embodiments of this application. Figure 1 The first mounting component 100 includes a first connecting portion 110 and a second connecting portion 120 connected together, and the second mounting component 200 includes a third connecting portion 210 and a fourth connecting portion 220 connected together.

[0070] The first connecting portion 110 and the third connecting portion 210 are configured to connect to different positions of the inner plate of the longitudinal beam 10, and the second connecting portion 120 and the fourth connecting portion 220 are connected; the first connecting portion 110, the second connecting portion 120, the third connecting portion 210, the fourth connecting portion 220 and the inner plate of the longitudinal beam 10 together define the first cavity 30.

[0071] The first mounting component 100 is connected to the inner plate of the longitudinal beam 10 through the first connecting part 110, the second mounting component 200 is connected to the inner plate of the longitudinal beam 10 through the third connecting part 210, and the first mounting component 100 and the second mounting component 200 are connected to the fourth connecting part 220 through the second connecting part 120. Thus, the first mounting component 100, the second mounting component 200 and the inner plate of the longitudinal beam 10 together form the first cavity 30.

[0072] The first connecting part 110 and the third connecting part 210 can be connected to the inner plate 10 of the longitudinal beam by welding or bolting, and fit together to form a first cavity 30 with a closed cross-section. The second connecting part 120 and the fourth connecting part 220 are matched in shape, so that the connection between the second connecting part 120 and the fourth connecting part 220 is a continuous and closed structure.

[0073] In this embodiment, the first mounting component 100 and the second mounting component 200 are connected to the inner plate of the longitudinal beam 10 through the first connecting part 110 and the second connecting part 120, and are connected to each other through the second connecting part 120 and the fourth connecting part 220, thereby enclosing and forming a closed first cavity 30, which improves the structural strength and bending stiffness of the battery mounting base.

[0074] In some embodiments, the first connecting portion 110 is configured to connect to the side of the inner longitudinal beam panel 10 opposite to the outer longitudinal beam panel 20 of the vehicle; the third connecting portion 210 is configured to connect to the side of the inner longitudinal beam panel 10 adjacent to the outer longitudinal beam panel 20, so that the first connecting portion 110 and the third connecting portion 210 are configured to connect to different positions of the inner longitudinal beam panel 10.

[0075] The first connecting part 110 is connected to the side of the inner plate 10 of the longitudinal beam opposite to the outer plate 20 of the automotive longitudinal beam, i.e., by welding or bolting, the first connecting part 110 is fixed to the inner side of the inner plate 10 of the longitudinal beam. This allows the first mounting part 100 to make full use of the inner space of the inner plate 10 of the longitudinal beam, avoiding the occupation of the effective layout area of ​​the engine compartment. At the same time, the structural strength of the inner plate 10 of the longitudinal beam enhances the stability of the connection. The third connecting part 210 is connected to the side of the inner plate 10 of the longitudinal beam adjacent to the outer plate 20 of the longitudinal beam. For example, the third connecting part 210 is connected to the top surface of the inner plate 10 of the longitudinal beam. This allows the third connecting part 210 to directly bear the vertical load from the battery 500 and distribute it evenly to the inner plate 10 of the longitudinal beam, while providing a supporting foundation for the top structure of the first cavity 30.

[0076] In some embodiments of this application, please refer to Figure 1 and Figure 4 The first end 221 of the fourth connecting part 220 is connected to the third connecting part 210. The second end 222 of the fourth connecting part 220 is configured to be bent toward the side opposite to the inner plate 10 of the longitudinal beam and extend toward the second connecting part 120. The second end 222 of the fourth connecting part 220 is connected to the second connecting part 120, and the battery mounting part 400 is connected to the second end 222 of the fourth connecting part 220.

[0077] The fourth connecting part 220 has two opposing ends, namely a first end 221 and a second end 222. The first end 221 is connected to the third connecting part 210, and the second end 222 is connected to the second connecting part 120. The second end 222 of the fourth connecting part 220 is bent toward the side away from the inner plate 10 of the longitudinal beam, which can form an "L", "Z" or "S" shaped spatial structure, so that the fourth connecting part 220 can cross the opening area of ​​the first cavity 30 and achieve effective connection with the second connecting part 120.

[0078] In this embodiment, the bending structure of the fourth connecting portion 220 forms a closed-loop connection between the second connecting portion 120 and the third connecting portion 210, which helps to form a closed structure of the cross-section of the first cavity 30. Furthermore, the bending structure of the fourth connecting portion 220 can improve its bending stiffness, thus enhancing its structural strength. Additionally, the bending structure can serve as a pre-defined energy absorption area, absorbing some of the impact energy through controllable deformation and mitigating the transmission of impact force to the battery 500.

[0079] In some embodiments of this application, a portion of the first mounting member 100 is bent in a first direction to form a first reinforcing portion 130, the first direction being parallel to the direction from the inner longitudinal beam plate 10 to the outer longitudinal beam plate 20 of the vehicle; or, a portion of the second mounting member 200 is bent in a second direction to form a second reinforcing portion 230, the second direction intersecting the first direction.

[0080] It should be noted that you should refer to [link / reference]. Figure 1 and Figure 2 The first direction X is parallel to the direction from the inner plate 10 of the longitudinal beam to the outer plate 20 of the longitudinal beam of the vehicle, that is, the first direction X is the width direction of the longitudinal beam or the width direction of the vehicle; the second direction Y intersects with the first direction X, that is, the second direction Y is the height direction of the longitudinal beam or the height direction of the vehicle.

[0081] The middle or edge region of the first mounting member 100 is bent along the width direction of the longitudinal beam to form a first reinforcing part 130. The middle or edge region of the second mounting member 200 is bent along the height direction of the longitudinal beam to form a second reinforcing part 230.

[0082] The first reinforcing part 130 and the second reinforcing part 230 form a raised or recessed structure through partial bending, which helps to increase the moment of inertia of the cross section and improve the bending stiffness of the mounting component. In this way, the first mounting component 100 and the second mounting component 200 provide bidirectional support against lateral impacts and vertical loads from the vehicle through the first reinforcing part 130 and the second reinforcing part 230, which can improve the structural strength of the first mounting component 100 and the second mounting component 200 in the width and height directions of the longitudinal beam, thereby improving the overall structural strength of the battery mounting base.

[0083] For example, both the first reinforcing part 130 and the second reinforcing part 230 can be elongated reinforcing ribs, and the cross-section of the reinforcing ribs can be "U-shaped", "V-shaped" or trapezoidal. In the embodiments of this application, the specific shape and number of reinforcing ribs are not limited, and can be set according to actual needs. For example, at least one first reinforcing part 130 is provided on the first mounting member 100, and at least one second reinforcing part 230 is provided on the second mounting member 200.

[0084] Meanwhile, the first reinforcing part 130 and the second reinforcing part 230 can transmit the impact force along the bending direction to the inner plate 10 of the longitudinal beam or the first cavity 30 when they collide, thereby dissipating the collision energy.

[0085] In some embodiments of this application, please refer to Figure 1 and Figure 3The battery mounting structure also includes a third mounting member 300, which is located on the side of the second mounting member 200 away from the first mounting member 100 and is configured to be connected to the outer panel 20 of the longitudinal beam of the vehicle; the third mounting member 300 supports the side of the battery mounting member 400 facing the second mounting member 200.

[0086] The third mounting member 300 is disposed on the side of the second mounting member 200 opposite to the first mounting member 100, that is, in the area close to the outer plate 20 of the vehicle longitudinal beam. One end of the third mounting member 300 can be rigidly connected to the inner wall of the outer plate 20 of the longitudinal beam by means of welding, bolts or clips, while the other end forms a support interface with the bottom edge of the battery mounting member 400.

[0087] Compared to the cantilever bracket which relies on the inner plate 10 of the longitudinal beam for support on only one side, this embodiment connects the outer plate 20 of the longitudinal beam with the third mounting component 300, which can form a support across both sides of the longitudinal beam. This disperses the vertical load of the battery 500 to both sides of the longitudinal beam, which helps to reduce the stress on the inner plate 10 of the longitudinal beam and provides more transmission paths for stress dispersion, thereby further improving the structural stability of the battery mounting foundation.

[0088] This embodiment improves the structural strength of the battery mounting foundation by setting a third mounting component 300 on the outer plate 20 of the longitudinal beam, and further reduces the risk of deformation of the battery mounting foundation.

[0089] In some embodiments of this application, please refer to Figure 1 The third mounting member 300 has a first end 310 and a second end 320 opposite to each other. The first end 310 is connected to the outer plate of the longitudinal beam 20, and the second end 320 is bent toward one side of the battery mounting member 400 and supports the side of the battery mounting member 400 facing the second mounting member 200.

[0090] The third mounting member 300 has a first end 310 and a second end 320 opposite to each other. The first end 310 is connected to the outer plate 20 of the longitudinal beam, and the second end 320 is bent toward one side of the battery mounting member 400 and forms a support surface that supports the battery mounting member 400.

[0091] The third mounting component 300 adapts to the space inside the vehicle's engine compartment by bending, fitting the installation positions of the first mounting component 100 and the third mounting component 300. This allows the second end 320 of the third mounting component 300 and the second end 222 of the fourth connecting portion 220 to form a double-point support, jointly bearing the weight of the battery mounting component 400. Furthermore, the bending of the third mounting component 300 creates a variable cross-section structure, increasing its moment of inertia and thus its bending stiffness. This contributes to improving the structural strength and stability of the entire battery mounting base.

[0092] In some embodiments of this application, please refer to Figure 3 A portion of the third mounting member 300 is bent toward the first direction X to form a third reinforcement 330, the first direction X being parallel to the direction from the inner longitudinal beam 10 to the outer longitudinal beam 20 of the vehicle; and / or, a portion of the edge of the third mounting member 300 is also bent along the second direction Y to form a first flange 340, the second direction Y intersecting the first direction X.

[0093] The third mounting member 300 is bent along the width direction of the longitudinal beam in its central or edge region to form a third reinforcing part 330. The third reinforcing part 330, through localized bending, forms a raised or recessed structure, which helps increase the moment of inertia of the cross-section of the third mounting member 300 and improves its bending stiffness. The third mounting member 300, through the third reinforcing part 330, provides support against lateral impacts from the vehicle, thereby improving the structural strength of the third mounting member 300 in the width direction of the longitudinal beam.

[0094] The third reinforcing part 330 may be a long strip-shaped reinforcing rib, and the cross-section of the reinforcing rib may be "U-shaped", "V-shaped" or trapezoidal. In the embodiments of this application, the specific shape and number of reinforcing ribs are not limited, and can be set according to actual needs. For example, at least one third reinforcing part 330 is provided on the third mounting member 300.

[0095] Please see Figure 3 A portion of the edge of the third mounting member 300 is bent along the second direction Y to form a first flange 340. The first flange 340 increases the shear stiffness of a portion of the edge of the third mounting member 300, helping to resist edge tearing caused by external forces. The third mounting member 300 provides bidirectional support for the vertical load of the vehicle through the first flange 340, which can improve the structural strength of the first mounting member 100 and the second mounting member 200 in the longitudinal beam height direction, thereby improving the overall structural strength of the battery mounting base. At the same time, the third reinforcing part 330 and the first flange 340 can guide and limit the installation of the battery 500, which helps to reduce the difficulty of positioning and installing the battery 500 and improve the installation stability of the battery 500.

[0096] For example, in the longitudinal direction of the beam, both ends of the third mounting member 300 are provided with first flanges 340 to enhance the structural strength of the edges at both ends of the third mounting member 300.

[0097] In some embodiments of this application, please refer to Figure 5 The battery mounting member 400 has a connecting platform 410 recessed toward the side of the second mounting member 200. A portion of the connecting platform 410 is also bent toward the side of the battery 500 to form a connecting reinforcement 420, which is connected to the battery 500.

[0098] The battery mounting component 400 is installed on the upper side of the first mounting component 100, the second mounting component 200, and the third mounting component 300, and can be connected by bolts or welding. The top surface of the battery mounting component 400 is provided with a recessed connecting platform 410, which extends along the length of the battery mounting component 400. It can be understood that the size of the connecting platform 410 matches the bottom structure of the battery 500.

[0099] The edge or central region of the connecting platform 410 is bent towards the battery 500, forming a connecting reinforcement 420 perpendicular to the platform surface. The connecting reinforcement 420 is a protruding structure formed by partial bending, extending beyond the connecting platform 410, which helps increase the moment of inertia of the cross-section and improve the bending stiffness of the battery mounting component 400. Simultaneously, the concave design of the connecting reinforcement 420 and the bending transition of the connecting platform 410 create a smooth load transfer path, which helps reduce stress concentration points. For example, the connecting reinforcement 420 can be a ring-shaped reinforcing rib, and the cross-section of the reinforcing rib can be "U-shaped," "V-shaped," or trapezoidal. In this embodiment, the specific shape and number of reinforcing ribs are not limited and can be set according to actual needs.

[0100] The connecting platform 410 and the connecting reinforcement 420 are structurally fitted into the bottom of the battery 500, and the weight of the battery 500 is evenly distributed to the main body of the battery mounting component 400 through the connecting platform 410. Multiple connecting reinforcements 420 form multiple limiting structures at the bottom of the battery 500, effectively resisting the torsional torque when the vehicle turns. Under vertical load and lateral force, the connecting reinforcement 420 acts as a rigid support point, directly transmitting the impact force to the reinforcing structure of the battery mounting component 400, such as the first cavity 30, the first reinforcement 130, and the second reinforcement 230.

[0101] In this embodiment, by providing a connecting reinforcement part 420 on the recessed connecting platform 410, the structural strength of the battery mounting component 400 is improved, and the structural strength of the battery mounting base is further improved. At the same time, the connecting platform 410 and the connecting reinforcement part 420 can reduce the installation difficulty of the battery 500 and improve the installation accuracy of the battery 500.

[0102] In some embodiments of this application, please refer to Figure 6 The battery mounting structure also includes a pressing member 600, which is located on the side of the battery 500 and abuts against the battery 500; the pressing member 600 is connected to at least one of the first mounting member 100 and the second mounting member 200.

[0103] In this embodiment, pressure is applied from the side of the battery 500 by the pressing member 600 to limit the lateral movement of the battery 500, effectively preventing the electrical connection from becoming loose or the casing from being damaged due to the battery 500 jumping.

[0104] It is understood that this embodiment does not limit the number of pressing components 600, and the number of pressing components 600 can be set according to actual needs. The pressing components 600 are disposed on the side of the battery 500, and can be disposed on the second direction Y of the longitudinal beam, along the length direction of the longitudinal beam; specifically, there are two pressing components 600, one of which is located on the first side of the battery 500, and the other is located on the opposite side of the first side of the battery 500.

[0105] The pressing member 600 is disposed on the side of the battery 500 opposite to the battery mounting member 400. Both ends of the pressing member 600 are rigidly connected to at least one of the first mounting member 100 and the second mounting member 200 by means of bolts, clips, or welding. For example, one end of the pressing member 600 is connected to the top of the first reinforcing portion 130 of the first mounting member 100, and the other end is connected to the top surface of the fourth connecting portion 220 of the second mounting member 200.

[0106] In some embodiments, an elastic buffer layer, such as a rubber pad, may be provided between the pressing member 600 and the battery 500 to absorb road vibration energy through the material damping characteristics.

[0107] Based on this, please refer to Figure 2 This application also provides an automobile, including longitudinal beams and the battery mounting structure in any of the above embodiments.

[0108] The longitudinal beam includes an inner plate 10 and an outer plate 20. The outer plate 20 and the inner plate 10 together define the second cavity 40, and the cross-sectional structure of the second cavity 40 is a closed structure in the direction perpendicular to the extension direction of the second cavity 40.

[0109] In the battery mounting structure, the first mounting member 100 and the second mounting member 200 are both connected to the inner plate 10 of the longitudinal beam, and the second mounting member 200, the first mounting member 100 and the inner plate 10 of the longitudinal beam together define the first cavity 30.

[0110] The inner longitudinal beam plate 10 and the outer longitudinal beam plate 20 can be connected by welding or bolts to form a closed second cavity 40 extending along the longitudinal direction of the vehicle. The cross-sectional structure of the second cavity 40 is a closed structure. When subjected to bending and torsional loads, the closed shape of the cross-section can evenly distribute stress, avoid stress concentration, and help enhance the overall rigidity of the vehicle body, improve vehicle handling and driving stability. The second mounting member 200, the first mounting member 100, and the inner longitudinal beam plate 10 together define the first cavity 30. The inner longitudinal beam plate 10 provides rigid support for the first cavity 30, reducing the deformation of the battery 500 mounting area.

[0111] For example, the first mounting member 100 is mounted on the side of the inner plate 10 of the longitudinal beam, the second mounting member 200 is mounted on the top surface of the inner plate 10 of the longitudinal beam, and the second cavity 40 is located between the first mounting member 100 and the second mounting member 200, thereby providing vertical support for the battery 500.

[0112] It is understood that the vehicle in this embodiment has the beneficial effects of the battery mounting structure in any of the above embodiments, so they will not be described in detail here.

[0113] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments.
