Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a structural component of a vehicle and a vehicle having the structural component. Background Technology

[0002] In related technologies, ultra-high strength components with conventional material thickness on vehicles are typically joined using techniques such as FDS (rotary tapping riveting) and SPR (spark piercing riveting) to maintain the component's strength. However, due to the high strength of the components, screws or rivets cannot quickly penetrate them, leading to increased manufacturing time and costs, and reduced production efficiency. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, one objective of this application is to provide a structural component for a vehicle that reduces the difficulty of fasteners passing through mounting walls, improves production efficiency, and reduces manufacturing time and costs.

[0004] This application further proposes a vehicle.

[0005] In a first aspect, embodiments of this application provide a structural component for a vehicle, comprising: multiple parts, all of which are metal parts, each part having a mounting wall, the mounting walls of the multiple parts being adapted to be passed through by fasteners to securely assemble the multiple parts, and at least one part having a mounting wall having a connected wall body and a thickness reduction area, the thickness of the thickness reduction area being less than the thickness of the corresponding wall body, and the thickness reduction area being adapted to be passed through by fasteners.

[0006] In the above technical solution, by setting a thickness reduction zone and having the fastener pass through the thickness reduction zone, the difficulty of the fastener passing through the mounting wall can be reduced. This is beneficial to increase the speed at which the fastener passes through the mounting wall while maintaining the strength of the parts, thereby improving production efficiency and reducing production time and cost.

[0007] In some embodiments, the thickness of the thinning region is greater than or equal to 0.75 times the thickness of the corresponding wall body and less than or equal to 0.8 times the thickness of the corresponding wall body.

[0008] In the above technical solution, by making the thickness of the thinning zone greater than or equal to 0.75 times the thickness of the corresponding wall body and less than or equal to 0.8 times the thickness of the corresponding wall body, the thickness of the thinning zone can be reasonably selected and set according to the actual situation. This reduces the risk of the thinning zone having too low strength due to its excessively small thickness, and also reduces the risk of fasteners not being able to pass through quickly due to its excessively large thickness. Thus, production efficiency is improved and production time and cost are reduced without affecting the structural strength of the parts.

[0009] In some embodiments, the wall body is disposed around the thickness reduction region along the circumference of the corresponding thickness reduction region.

[0010] In the above technical solution, by setting the wall body around the corresponding thickness reduction area in the circumference, the wall body can form a constraint around the thickness reduction area, reducing the risk of local stress concentration in the thickness reduction area, thereby reducing the risk of the installation wall's compressive or bending capacity decreasing due to local thinning of the installation wall, which is conducive to effectively maintaining the load-bearing capacity and structural strength of the installation wall.

[0011] In some embodiments, the mounting wall having the thickness reduction region also has a transition region connecting the respective wall body and the respective thickness reduction region.

[0012] In the above technical solution, by making the mounting wall with the thickness reduction area also have a transition area, and the transition area connects the corresponding wall body and the corresponding thickness reduction area, the connection between the wall body and the thickness reduction area can be made smooth, reducing the risk of stress concentration at the connection between the wall body and the corresponding thickness reduction area, thereby reducing the risk of deformation or even cracking at the connection between the wall body and the corresponding thickness reduction area due to sudden thickness changes, which is conducive to improving the overall strength and durability of the mounting wall.

[0013] In some embodiments, the thickness of the transition zone gradually increases from the thickness reduction region toward the wall body direction.

[0014] In the above technical solution, by gradually increasing the thickness of the transition zone from the thickness reduction zone to the wall body, the connection between the wall body and the thickness reduction zone can be made smoother. The gradually increasing thickness of the transition zone can more effectively disperse stress, reduce the risk of stress concentration in the transition zone caused by abrupt changes in thickness, and further enhance the connection strength between the wall body and the thickness reduction zone, thereby improving the overall load-bearing capacity of the installed wall.

[0015] In some embodiments, the transition region is annular and is disposed around the thickness reduction region along the circumference of the corresponding thickness reduction region.

[0016] In the above technical solution, by making the transition zone annular and surrounding the corresponding thickness reduction zone in the circumference, the thickness reduction zone can be uniformly transitioned in the circumference, thereby reducing the risk of stress concentration at any connection between the wall body and the corresponding thickness reduction zone, reducing the risk of damage to the installation wall structure due to excessive local stress, enhancing the deformation resistance of the overall structure of the components, and improving the overall strength and durability of the installation wall.

[0017] In some embodiments, the shape of the thickness reduction region is polygonal or circular.

[0018] In the above technical solution, by making the shape of the thickness reduction area polygonal or circular, the shape design of the thickness reduction area can be flexible, which is beneficial to the fact that the shape and size of the thickness reduction area can be reasonably selected and set according to the actual situation to adapt to different application scenarios.

[0019] In some embodiments, the mounting wall with the thickness reduction area is provided with a reinforcing structure, which is located on one side of the corresponding mounting wall and is connected to both the corresponding wall body and the thickness reduction area.

[0020] In the above technical solution, by providing a reinforcing structure on the mounting wall with the thickness reduction zone, the reinforcing structure is located on one side of the corresponding mounting wall and is connected to both the corresponding wall body and the thickness reduction zone. This can enhance the strength of the mounting wall near the thickness reduction zone and reliably increase the connection stability between the wall body and the corresponding thickness reduction zone. This further reduces the risk of deformation or even cracking at the connection between the wall body and the corresponding thickness reduction zone, which is conducive to further improving the load-bearing capacity of the overall structure of the mounting wall, thereby further improving the overall strength and durability of the mounting wall.

[0021] In some embodiments, the reinforcing structure is constructed as a reinforcing rib.

[0022] In the above technical solution, by constructing the reinforcing structure as a reinforcing rib, the connection reliability between the wall body and the corresponding thickness reduction zone can be improved without significantly increasing weight and cost, thereby further improving the strength of the installed wall. Furthermore, the reinforcing rib has a simple structure, is easy to process and manufacture, and is conducive to improving production efficiency, further reducing production time and cost.

[0023] In some embodiments, multiple components are configured as a vehicle body structure.

[0024] In the above technical solution, by constructing multiple components as body structures, the body structures can be reliably assembled in the corresponding positions on the vehicle. This helps to reduce the difficulty of connecting different body structures on the vehicle, and enables reliable connection between different body structures. As a result, production efficiency is improved while maintaining the strength of the body structure, and production time and cost are reduced.

[0025] Secondly, embodiments of this application also provide a vehicle, including the aforementioned vehicle structural components.

[0053] In this embodiment of the application, the battery cell can be a secondary battery, which refers to a battery cell that can be recharged to activate the active materials and continue to be used after the battery cell has been discharged.

[0054] The battery cell can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and the embodiments of this application are not limited to this.

[0055] Battery cells can be cylindrical, flat, cuboid, or other shapes, and this application embodiment is not limited to any of these. Battery cells are generally classified into three types according to their packaging method: cylindrical battery cells, square battery cells, and pouch battery cells, and this application embodiment is not limited to any of these types either.

[0056] The battery device mentioned in the embodiments of this application may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells, which are connected in series, parallel, or mixed connections via a busbar.

[0057] In some embodiments, a battery cell assembly is typically formed by arranging multiple battery cells.

[0058] As an example, a battery cell assembly can be a battery module, which is formed by arranging and fixing multiple battery cells together to form an independent module. As another example, a battery module can be formed by bundling multiple battery cells together with cable ties.

[0059] In some embodiments, the battery device may be a battery pack, which includes a housing and one or more individual battery cell assemblies housed within the housing.

[0060] As an example, the battery cell assembly can be a battery module, which can be housed in a housing by fixing the battery module in the housing.

[0061] As an example, battery cell assemblies can also be housed in a housing by directly fixing multiple battery cells to the housing.

[0062] As an example, the enclosure may include a first enclosure and a second enclosure. The first enclosure and the second enclosure are fastened together to form a closed space inside the enclosure, which can house the individual battery cells; that is, the individual battery cells are installed within the closed space. Here, "closed" refers to covering or closing, which can be sealed or not sealed. The first enclosure may be one of an upper enclosure and a lower enclosure, and the second enclosure may be the other of an upper enclosure and a lower enclosure.

[0063] In some embodiments, the housing may be part of the vehicle's chassis structure. For example, a portion of the housing may be at least a part of the vehicle's floor, or a portion of the housing may be at least a part of the vehicle's crossbeams and longitudinal beams.

[0064] The technical solutions described in the embodiments of this application are applicable to various electrical devices that use individual battery cells, such as mobile phones, portable devices, laptops, electric vehicles, electric toys, power tools, vehicles, ships, and spacecraft. For example, spacecraft include airplanes, rockets, space shuttles, and spacecraft.

[0065] A battery cell includes a casing, electrode assembly, and electrolyte. The casing houses the electrode assembly and electrolyte. The electrode assembly consists of an anode electrode, a cathode electrode, and a separator. The battery cell primarily functions by the movement of metal ions between the anode and cathode electrodes. The anode electrode includes an anode current collector and an anode active material layer. The anode active material layer is coated on the surface of the anode current collector. The uncoated anode current collector protrudes beyond the coated anode current collector and serves as the anode tab. Taking a lithium-ion battery as an example, the anode current collector can be made of aluminum, and the anode active material can be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide, etc. The cathode electrode includes a cathode current collector and a cathode active material layer. The cathode active material layer is coated on the surface of the cathode current collector. The uncoated cathode current collector protrudes beyond the coated cathode current collector and serves as the cathode tab. The cathode current collector can be made of copper, and the cathode active material can be carbon or silicon, etc. To ensure that a large current can be passed without melting, there are multiple anode tabs stacked together, and there are multiple cathode tabs stacked together.

[0066] The separator can be made of PP (polypropylene) or PE (polyethylene), etc. Furthermore, the electrode assembly can be a wound structure or a stacked structure; the embodiments of this application are not limited to these.

[0067] In recent years, battery devices have developed rapidly and can be installed in vehicles, laptops, electric bicycles, electric toys, etc. This application uses the installation of battery devices in new energy vehicles as an example for illustration. In recent years, new energy vehicles have experienced rapid development. In the field of electric vehicles, battery devices, as the power source of electric vehicles, play an irreplaceable and crucial role. As a core component of new energy vehicles, battery devices have high requirements in terms of reliability.

[0068] In related technologies, ultra-high strength components with conventional material thickness on vehicles are typically joined using techniques such as FDS (rotary tapping riveting) and SPR (spark piercing riveting) to maintain component strength. However, due to the high strength of the components, screws or rivets cannot quickly penetrate them, leading to increased manufacturing time and costs, and reduced production efficiency.

[0069] Based on the above considerations, in order to solve the technical problem that fasteners are difficult to quickly pass through components, this application proposes a structural component for a vehicle, including: multiple components, all of which are metal parts, each component having a mounting wall, multiple mounting walls of the multiple components being adapted to be passed through by fasteners to securely assemble the multiple components, at least one component's mounting wall having a connected wall body and a thickness reduction region, the thickness of the thickness reduction region being less than the thickness of the corresponding wall body, and the thickness reduction region being adapted to be passed through by fasteners.

[0070] In such structural components, by setting a thickness reduction zone and having the fastener pass through the thickness reduction zone, the difficulty of the fastener passing through the mounting wall can be reduced. This is beneficial to increase the speed at which the fastener passes through the mounting wall while maintaining the strength of the components, thereby improving production efficiency and reducing production time and costs.

[0071] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle 200 provided in some embodiments of this application. The vehicle 200 can be a gasoline-powered vehicle or a new energy vehicle; a new energy vehicle can be a pure electric vehicle, a hybrid electric vehicle, or a range-extended electric vehicle, etc. A battery device 100 is mounted on the chassis of the vehicle 200. The battery device 100 can be used to power the vehicle 200; for example, the battery device 100 can serve as the operating power source for the vehicle 200. The vehicle 200 may also include a controller 201 and a motor 202. The controller 201 is used to control the battery device 100 to supply power to the motor 202, for example, to meet the power needs of the vehicle 200 during starting, navigation, and driving.

[0072] In some embodiments of this application, the battery device 100 can not only serve as the operating power source for the vehicle 200, but also as the driving power source for the vehicle 200, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 200.

[0073] In some embodiments of this application, when the vehicle 200 is a new energy vehicle, the multiple components 1 can be the housing 101 of the battery device 100 and the chassis of the vehicle 200, respectively. Furthermore, the housing 101 can have a mounting beam, and the fasteners 500 pass through the mounting beam and the chassis to fix the battery device 100 to the vehicle 200.

[0074] In some embodiments of this application, multiple components 1 may be the body-in-white and seats of the vehicle 200, and fasteners 500 pass through the body-in-white and seats to fix the body-in-white and seats.

[0075] Please refer to Figure 2 , Figure 2 This is an exploded view of the structure of a battery device 100 provided in some embodiments of this application. The battery device 100 includes a housing 101 and a plurality of battery cells 400, which are housed within the housing 101. The housing 101 provides assembly space for the battery cells 400, and the housing 101 can adopt various structures. In some embodiments, the housing 101 may include a first housing 102 and a second housing 103, which overlap each other, and the first housing 102 and the second housing 103 together define an assembly space for accommodating the battery cells 400. The second housing 103 can be a hollow structure open at one end, and the first housing 102 can be a plate-like structure. The first housing 102 covers the open side of the second housing 103 so that the first housing 102 and the second housing 103 together define the assembly space. Alternatively, the first housing 102 and the second housing 103 can both be hollow structures open on one side, with the open side of the first housing 102 covering the open side of the second housing 103. Of course, the housing 101 formed by the first housing 102 and the second housing 103 can be of various shapes, such as a cylinder, a cuboid, etc.

[0076] The following is for reference. Figures 3-7 Describes a structural component 300 according to an embodiment of this application.

[0077] like Figures 3-7 As shown, the structural component 300 according to an embodiment of this application includes: a plurality of components 1, all of which are metal parts, each component 1 having a mounting wall 11, the mounting walls 11 of the plurality of components 1 being adapted to be passed through by fasteners 500 to fix the plurality of components 1 in assembly, at least one component 1 having a mounting wall 11 having a connected wall body 111 and a thickness reduction region 112, the thickness of the thickness reduction region 112 being less than the thickness of the corresponding wall body 111, and the thickness reduction region 112 being adapted to be passed through by fasteners 500.

[0078] Component 1 can be configured as the battery housing 101 on the vehicle 200, or as the chassis of the vehicle 200, but this application is not limited to these. Multiple components 1 can also be configured as any structural parts that need to be connected. All multiple components 1 are metal parts; for example, multiple components 1 can be, but are not limited to, made of steel, aluminum, etc. Each component 1 has a mounting wall 11. When multiple components 1 need to be fixedly assembled, the mounting walls 11 of the multiple components 1 are arranged opposite each other, and fasteners 500 are passed through the mounting walls 11 in sequence to fix the multiple components 1 together.

[0079] As some embodiments of this application, the mounting wall 11 of a component 1 has a connected wall body 111 and a thickness reduction region 112. As some embodiments of this application, the mounting walls 11 of multiple components 1 all have connected wall bodies 111 and thickness reduction regions 112. The wall bodies 111 and thickness reduction regions 112 may be connected by, but are not limited to, integral molding. The thickness of the thickness reduction region 112 is less than the thickness of the corresponding wall body 111.

[0080] Fastener 500 can be, but is not limited to, rivets, bolts, etc. When multiple parts 1 need to be fixedly assembled, fastener 500 passes through the thickness reduction zone 112 of multiple mounting walls 11 in sequence. This setting can reduce the difficulty of fastener 500 passing through mounting walls 11, which is conducive to increasing the speed of fastener 500 passing through mounting walls 11 while keeping the strength of parts 1 unchanged, thereby improving production efficiency and reducing production time and cost.

[0081] It should be noted that the fixed assembly of multiple components 1 can be two components 1, three components 1, or even more components 1. Taking the example of each mounting wall 11 having a thickness reduction area 112, when two components 1 are fixedly assembled, the two mounting walls 11 of the two components 1 are arranged opposite each other, and the corresponding thickness reduction areas 112 of the two mounting walls 11 are arranged opposite each other. Fasteners 500 are sequentially inserted into the two thickness reduction areas 112 to fix the two components 1. When three components 1 are fixedly assembled, the three mounting walls 11 of the three components 1 are arranged opposite each other, and the corresponding thickness reduction areas 112 of the three mounting walls 11 are arranged opposite each other. Fasteners 500 are sequentially inserted into the three thickness reduction areas 112 to fix the three components 1. When more than one component 1 is fixedly assembled, the same principle applies, and will not be elaborated further.

[0082] Specifically, as some embodiments of this application, the wall body 111 and the thickness reduction zone 112 of component 1 can be formed by cold forging using mold 600, the structure of mold 600 being as follows: Figure 7As shown, mold 600 may include a first mold 601, a second mold 602, and an ejector pin 603. In some embodiments of this application, the ejector pin 603 is fixedly connected to the first mold 601. In some embodiments of this application, the ejector pin 603 is fixedly connected to the second mold 602. This application uses the fixed connection between the ejector pin 603 and the first mold 601 as an example for illustration, and the ejector pin 603 is disposed on the surface of the first mold 601 facing the second mold 602.

[0083] When processing component 1, the mounting wall 11 of component 1 can be placed between the first mold 601 and the second mold 602, and the target position where the fastener 500 needs to be inserted is set to correspond with the push rod 603. The first mold 601 and the second mold 602 can be driven to move towards the other, or the first mold 601 and the second mold 602 can be driven to move towards each other together. Under the action of the push rod 603, part of the mounting wall 11 is thinned so that the mounting wall 11 with the connected wall body 111 and the thickness reduction area 112 is processed and formed.

[0084] When two metal parts 1 need to be fixedly connected, one of the parts 1 can be processed by mold 600 to make the mounting wall 11 of the part 1 have a connected wall body 111 and a thickness reduction area 112. The thickness reduction area 112 of the part 1 is set to correspond to the mounting position of the mounting wall 11 of the other part 1. The fastener 500 passes through the center position of the thickness reduction area 112 and through the mounting position of the other part 1 to fix the two parts 1 together.

[0085] In the above technical solution, by setting a thickness reduction zone 112 and having the fastener 500 pass through the thickness reduction zone 112, the difficulty of the fastener 500 passing through the mounting wall 11 can be reduced. This is beneficial to increase the speed at which the fastener 500 passes through the mounting wall 11 while keeping the strength of the component 1 unchanged, thereby improving production efficiency and reducing production time and cost.

[0086] According to some embodiments of this application, such as Figure 6 As shown, the thickness of the thinning region 112 is greater than or equal to 0.75 times the thickness of the corresponding wall body 111 and less than or equal to 0.8 times the thickness of the corresponding wall body 111.

[0087] The thickness dimension of the thinning region 112 is D1, and the thickness dimension of the corresponding wall body 111 is D2, satisfying the relationship: 0.75D2≤D1≤0.8D2. That is, the thickness dimension D1 of the thinning region 112 can be any value between 0.75 times and 0.8 times the thickness dimension of the corresponding wall body 111. For example, the thickness dimension D1 of the thinning region 112 can be 0.75D2, 0.78D2, or 0.8D2, etc. However, this application is not limited to this. 1 can also be any other value between 0.75 times the thickness of the corresponding wall body 111 and 0.8 times the thickness of the corresponding wall body 111. This setting allows the thickness of the thickness reduction zone 112 to be reasonably selected according to the actual situation, reducing the risk of the thickness reduction zone 112 having too low strength due to the thickness being too small, and also reducing the risk of the fastener 500 not being able to pass quickly due to the thickness being too large. Thus, production efficiency is improved and production time and cost are reduced without affecting the structural strength of the component 1.

[0088] In the above technical solution, by making the thickness of the thinning area 112 greater than or equal to 0.75 times the thickness of the corresponding wall body 111 and less than or equal to 0.8 times the thickness of the corresponding wall body 111, the thickness of the thinning area 112 can be reasonably selected and set according to the actual situation. This reduces the risk of the thinning area 112 having too low strength due to its thickness being too small, and also reduces the risk of the fastener 500 not being able to pass through quickly due to its thickness being too large. Thus, production efficiency is improved and production time and cost are reduced without affecting the structural strength of the component 1.

[0089] According to some embodiments of this application, such as Figure 3 and Figure 4 As shown, the wall body 111 is arranged around the thickness reduction area 112 along the circumference of the corresponding thickness reduction area 112.

[0090] Wherein, along the circumference of the corresponding thickness reduction area 112, the wall body 111 is arranged around the thickness reduction area 112. This arrangement makes the arrangement of the wall body 111 and the thickness reduction area 112 reasonable. By arranging the wall body 111 around the thickness reduction area 112 along the circumference of the corresponding thickness reduction area 112, the wall body 111 can form a constraint around the thickness reduction area 112, reducing the risk of local stress concentration in the thickness reduction area 112. This reduces the risk of the installation wall 11's compressive or bending capacity decreasing due to local thinning of the installation wall 11, and helps to effectively maintain the load-bearing capacity and structural strength of the installation wall 11.

[0091] Furthermore, component 1 may have a wall body 111 and a thickness reduction region 112, with the wall body 111 arranged circumferentially around the corresponding thickness reduction region 112. Component 1 may also have a wall body 111 and multiple thickness reduction regions 112, with the wall body 111 arranged circumferentially around the multiple thickness reduction regions 112. When the assembly reliability of component 1 is poor, multiple thickness reduction regions 112 can be provided on component 1, and multiple fasteners 500 can pass through the corresponding multiple thickness reduction regions 112 to improve the assembly reliability of component 1.

[0092] In the above technical solution, by setting the wall body 111 around the thickness reduction area 112 in the circumferential direction along the corresponding thickness reduction area 112, the wall body 111 can form a constraint around the thickness reduction area 112, reducing the risk of local stress concentration in the thickness reduction area 112, thereby reducing the risk of the installation wall 11's compressive or bending capacity decreasing due to local thinning of the installation wall 11, which is conducive to effectively maintaining the load-bearing capacity and structural strength of the installation wall 11.

[0093] According to some embodiments of this application, such as Figure 6 As shown, the mounting wall 11 with the thickness reduction region 112 also has a transition region 113, which connects the corresponding wall body 111 and the corresponding thickness reduction region 112.

[0094] The transition zone 113 can be connected to the corresponding wall body 111 and the corresponding thickness reduction zone 112 through an integral molding method, but not limited to this method. This allows the transition zone 113 to be connected between the corresponding wall body 111 and the corresponding thickness reduction zone 112. By setting the transition zone 113 between the wall body 111 and the corresponding thickness reduction zone 112, the connection between the wall body 111 and the thickness reduction zone 112 can be made smoother, reducing the risk of stress concentration at the connection between the wall body 111 and the corresponding thickness reduction zone 112. This reduces the risk of deformation or even cracking at the connection between the wall body 111 and the corresponding thickness reduction zone 112 due to sudden changes in thickness, which is beneficial to improving the overall strength and durability of the installed wall 11.

[0095] In the above technical solution, by making the mounting wall 11 with the thickness reduction area 112 also have a transition area 113, the transition area 113 is connected between the corresponding wall body 111 and the corresponding thickness reduction area 112, which can make the connection between the wall body 111 and the thickness reduction area 112 smooth, reduce the risk of stress concentration at the connection between the wall body 111 and the corresponding thickness reduction area 112, thereby reducing the risk of deformation or even cracking at the connection between the wall body 111 and the corresponding thickness reduction area 112 due to sudden thickness changes, which is beneficial to improving the overall strength and durability of the mounting wall 11.

[0096] According to some embodiments of this application, such as Figure 6 As shown, the thickness of the transition zone 113 gradually increases from the thickness reduction zone 112 to the wall body 111.

[0097] In this design, the thickness of the transition zone 113 gradually increases from the thickness reduction zone 112 to the wall body 111. This arrangement makes the connection between the wall body 111 and the thickness reduction zone 112 smoother, and the gradually increasing thickness of the transition zone 113 can more effectively disperse stress, reduce the risk of stress concentration in the transition zone 113 due to abrupt changes in thickness, and further enhance the connection strength between the wall body 111 and the thickness reduction zone 112, thereby improving the overall load-bearing capacity of the installed wall 11.

[0098] In the above technical solution, by gradually increasing the thickness of the transition zone 113 from the thickness reduction zone 112 to the wall body 111, the connection between the wall body 111 and the thickness reduction zone 112 can be made smoother. Moreover, the gradually increasing thickness of the transition zone 113 can more effectively disperse stress, reduce the risk of stress concentration in the transition zone 113 due to abrupt changes in thickness, and further enhance the connection strength between the wall body 111 and the thickness reduction zone 112, thereby improving the overall load-bearing capacity of the installed wall 11.

[0099] According to some embodiments of this application, such as Figures 3-4 As shown, the transition region 113 is annular and is arranged around the thickness reduction region 112 along the circumference of the corresponding thickness reduction region 112.

[0100] The transition zone 113 is annular and is arranged around the corresponding thickness reduction zone 112 along the circumference of the thickness reduction zone 112. This arrangement makes the transition zone 113 reasonably positioned. The annular transition zone 113 allows for a uniform transition in the circumference of the thickness reduction zone 112, thereby reducing the risk of stress concentration at any connection point between the wall body 111 and the corresponding thickness reduction zone 112, reducing the risk of structural damage to the mounting wall 11 due to excessive local stress, enhancing the overall deformation resistance of the component 1, and improving the overall strength and durability of the mounting wall 11.

[0101] In the above technical solution, by making the transition zone 113 annular and surrounding the corresponding thickness reduction zone 112 in the circumference, the thickness reduction zone 112 can be uniformly transitioned in the circumference, thereby reducing the risk of stress concentration at any connection between the wall body 111 and the corresponding thickness reduction zone 112, reducing the risk of structural damage to the mounting wall 11 due to excessive local stress, enhancing the deformation resistance of the overall structure of the component 1, and improving the overall strength and durability of the mounting wall 11.

[0102] According to some embodiments of this application, such as Figure 4As shown, the shape of the thickness reduction region 112 is polygonal or circular.

[0103] The thickness reduction area 112 can be polygonal or circular. For example, the thickness reduction area 112 can be circular, quadrilateral, pentagon, etc., but this application is not limited to these. The thickness reduction area 112 can also be other polygonal shapes, which allows for flexible design of the shape of the thickness reduction area 112. As some embodiments of this application, the thickness reduction area 112 is a regular quadrilateral with a side length of D3. D3 satisfies the relationship: 10mm≤D3≤30mm. That is, the side length D3 of the regular quadrilateral thickness reduction area 112 can be any value between 10mm and 30mm. For example, the side length D3 of the regular quadrilateral thickness reduction area 112 can be 10mm, 20mm, or 30mm.

[0104] In some embodiments of this application, the thickness reduction region 112 is circular in shape with a diameter of D4, where D4 satisfies the relationship: 10mm ≤ D4 ≤ 30mm. That is, the diameter D4 of the circular thickness reduction region 112 can be any value between 10mm and 30mm, for example, 10mm, 20mm, or 30mm. This design allows the shape and size of the thickness reduction region 112 to be reasonably selected according to actual conditions to adapt to different application scenarios.

[0105] In the above technical solution, by making the shape of the thickness reduction area 112 polygonal or circular, the shape design of the thickness reduction area 112 can be flexible, which is beneficial to the fact that the shape and size of the thickness reduction area 112 can be reasonably selected and set according to the actual situation to adapt to different application scenarios.

[0106] According to some embodiments of this application, the mounting wall 11 having a thickness reduction region 112 is provided with a reinforcing structure (not shown in the figure), the reinforcing structure is located on one side of the corresponding mounting wall 11, and the reinforcing structure is connected to both the corresponding wall body 111 and the thickness reduction region 112.

[0107] The mounting wall 11 with the thickness reduction region 112 is provided with a reinforcing structure, for example, the reinforcing structure can be constructed as a reinforcing rib or a reinforcing plate. The reinforcing structure is located on one side of the corresponding mounting wall 11. Furthermore, the thickness reduction region 112 of the mounting wall 11 is recessed towards the inside of the mounting wall 11, and the reinforcing structure is located on the recessed side of the corresponding mounting wall 11. The reinforcing structure is connected to both the corresponding wall body 111 and the thickness reduction area 112. For example, the reinforcing structure can be connected to the corresponding wall body 111 and the thickness reduction area 112 by means of welding, bonding, etc. By connecting the reinforcing structure to both the corresponding wall body 111 and the thickness reduction area 112, the strength of the mounting wall 11 near the thickness reduction area 112 can be enhanced. The reinforcing structure can also reliably increase the connection stability between the wall body 111 and the corresponding thickness reduction area 112, further reducing the risk of deformation or even cracking at the connection between the wall body 111 and the corresponding thickness reduction area 112. This is conducive to further improving the load-bearing capacity of the overall structure of the mounting wall 11, thereby further improving the overall strength and durability of the mounting wall 11.

[0108] In the above technical solution, by providing a reinforcing structure to the mounting wall 11 with the thickness reduction area 112, the reinforcing structure is located on one side of the corresponding mounting wall 11 and is connected to both the corresponding wall body 111 and the thickness reduction area 112. This can enhance the strength of the mounting wall 11 near the thickness reduction area 112, and also make the reinforcing structure reliably increase the connection stability between the wall body 111 and the corresponding thickness reduction area 112. This further reduces the risk of deformation or even cracking at the connection between the wall body 111 and the corresponding thickness reduction area 112, which is conducive to further improving the load-bearing capacity of the overall structure of the mounting wall 11, thereby further improving the overall strength and durability of the mounting wall 11.

[0109] According to some embodiments of this application, the reinforcing structure (not shown in the figure) is constructed as a reinforcing rib.

[0110] Among them, the reinforcement structure is constructed as a reinforcing rib, which can make the reinforcement structure set reasonably. Using the reinforcing rib as a reinforcement structure can improve the connection reliability between the wall body 111 and the corresponding thickness reduction area 112 without significantly increasing the weight and cost, thereby further improving the strength of the installed wall 11. In addition, the construction of the reinforcing rib is simple, easy to process and manufacture, which is conducive to improving production efficiency and further reducing the production time and cost.

[0111] In the above technical solution, by constructing the reinforcing structure as a reinforcing rib, the connection reliability between the wall body 111 and the corresponding thickness reduction area 112 can be improved without significantly increasing the weight and cost, thereby further improving the strength of the installed wall 11. In addition, the reinforcing rib has a simple structure, is easy to process and manufacture, and is conducive to improving production efficiency and further reducing the time and cost of production and manufacturing.

[0112] According to some embodiments of this application, multiple components 1 are configured as vehicle body structure 2.

[0113] In some embodiments of this application, component 1 can be constructed as the body-in-white of vehicle 200. In other embodiments, component 1 can also be constructed as component 1 on vehicle 200, such as battery housing 101, seats, etc. By constructing multiple components 1 as body structures 2, the body structures 2 can be reliably assembled at corresponding positions on vehicle 200. This reduces the difficulty of connecting different body structures 2 on vehicle 200, ensuring reliable connection between different body structures 2. This improves production efficiency and reduces manufacturing time and costs while maintaining the strength of the body structures 2.

[0114] In the above technical solution, by constructing multiple parts 1 as body structure 2, the body structure 2 can be reliably assembled on the corresponding position on the vehicle 200, which helps to reduce the connection difficulty of different body structures 2 on the vehicle 200, and enables different body structures 2 to be reliably connected. This improves production efficiency and reduces production time and cost while maintaining the strength of the body structure 2.

[0115] The vehicle 200 according to an embodiment of this application includes the structural component 300 of the above embodiment. By providing a thickness reduction zone 112 and having the fastener 500 pass through the thickness reduction zone 112, the difficulty of the fastener 500 passing through the mounting wall 11 can be reduced. This is beneficial to increasing the speed at which the fastener 500 passes through the mounting wall 11 while maintaining the strength of the component 1, thereby improving the production efficiency of the vehicle 200 and reducing the production time and cost of the vehicle 200.

[0116] According to some embodiments of this application, see Figure 6 As shown, this application provides a structural component 300, which includes two parts 1. One part 1 is a high-strength thermoformed body-in-white and the other part 1 is a battery housing 101. Both the body-in-white and the housing 101 are metal parts.

[0117] The body-in-white is made of high-strength steel of 1300MPa and above, which is hot-formed. The mounting wall 11 of the body-in-white is placed between the first mold 601 and the second mold 602, and the position to be assembled is placed in correspondence with the push rod 603. The push rod 603 is a cylinder with a diameter of 30mm. It drives the first mold 601 to move toward the second mold 602. Under the action of the push rod 603, part of the mounting wall 11 is thinned so that the mounting wall 11 with the connected wall body 111 and the thickness reduction area 112 is stamped and formed.

[0118] The height of the top rod 603 is 0.2 times the thickness of the wall body 111, so that the thickness of the thickness reduction zone 112 is 0.8 times the thickness of the corresponding wall body 111, and the wall body 111 is arranged around the thickness reduction zone 112 circumferentially. The mounting wall 11 of the body-in-white also has a transition zone 113, which connects the corresponding wall body 111 and the corresponding thickness reduction zone 112. From the thickness reduction zone 112 to the wall body 111, the thickness of the transition zone 113 gradually increases, and the transition zone 113 is annular and is arranged around the thickness reduction zone 112 circumferentially.

[0119] After the mounting wall 11 is stamped, the mounting beam of the box body 101 is set at a suitable position on the vehicle 200, and the assembly position of the mounting beam is set opposite to the thickness reduction area 112 of the body-in-white. The fastener 500 passes through the thickness reduction area 112 and the assembly position of the mounting beam, so that the box body 101 is fixedly assembled to the body-in-white. By setting the thickness reduction area 112 and having the fastener 500 pass through the thickness reduction area 112, the difficulty of the fastener 500 passing through the high-strength body-in-white can be reduced. This is beneficial to increase the speed at which the fastener 500 passes through the mounting wall 11 while maintaining the strength of the body-in-white, thereby improving the production efficiency of the vehicle 200 and reducing the production time and cost of the vehicle 200.

[0120] It should be noted that this application is not limited to the high-strength thermoformed parts mentioned in this application, but includes, but is not limited to, high-strength parts formed by processes such as stamping, rolling, and extrusion.

[0121] The forming method of the thickness reduction region 112 in this application is not limited to the cold heading forming method mentioned in this application, but includes, but is not limited to, the thickness reduction region 112 formed by processes such as thermoforming and extrusion.
