Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to protective components, battery guard plates, battery systems, processing systems, and vehicles. Background Technology

[0002] With increasingly stringent requirements for lightweighting, composite panels are being used more and more as protective components in fields such as vehicles and construction. Composite panels are formed by combining two or more layers of materials and typically possess high strength and wear resistance, making them ideal protective materials.

[0003] In related technologies, the protective component includes a core layer, a first surface layer, and a second surface layer, with the first and second surface layers respectively disposed on the surfaces of both sides of the core layer. During the processing of the protective component, the first and second surface layers need to be laminated onto both sides of the core layer.

[0004] However, the first and second outer layers are usually rolls, which can be quite long, while the core layer is a sheet material, which is usually limited in length. Therefore, it is difficult to match the length of the core layer with that of the outer layer, so the core layer and the outer layer cannot be continuously formed into a protective component, which can easily affect the processing efficiency of the protective component. Utility Model Content

[0005] In view of this, the present invention provides a protective component, a battery guard plate, a battery system, a processing system, and a vehicle to solve or improve the problem that the length of the core layer is difficult to match the length of the surface layer during the processing of the protective component.

[0006] In a first aspect, this utility model provides a protective component, comprising:

[0007] The plate, the number of which is at least two, is arranged and joined together in sequence along a direction perpendicular to the thickness direction of the plate to form a core layer structure;

[0008] A first surface layer and a second surface layer, wherein the first surface layer covers and is connected to a first side surface of the core structure, and the second surface layer covers and is connected to a second side surface of the core structure.

[0009] In one optional embodiment, one of two adjacent plates is provided with a first limiting portion and the other is provided with a second limiting portion. The first limiting portion and the second limiting portion are at least partially overlapped in the thickness direction of the plates, so that the first limiting portion and the second limiting portion form a limit in the thickness direction of the plates.

[0010] In one optional embodiment, the protective member further includes a positioning member, which passes through the first limiting portion and the second limiting portion along the thickness direction of the plates at the joint of two adjacent plates.

[0011] In one optional embodiment, both the first limiting part and the second limiting part are configured as limiting blocks, the surface of the first limiting part away from the second limiting part is flush with the first side surface of the plate, and the surface of the second limiting part away from the first limiting part is flush with the second side surface of the plate.

[0012] Alternatively, one of the first limiting part and the second limiting part may be configured as a limiting block, and the other may be configured as a limiting recess into which the limiting block may be inserted.

[0013] In one alternative embodiment, at least one of the first surface layer and the second surface layer includes a fiber layer, the fiber layer being impregnated with adhesive and bonded to the core layer structure;

[0014] Alternatively, at least one of the first and second surface layers may include a metal layer or a plastic layer.

[0015] In one alternative embodiment, in the core layer structure, at least one of the plates is made of a different material than the other plates.

[0016] And / or, the board material includes at least two splicing plates, which are arranged and joined sequentially along a direction perpendicular to the thickness direction of the board material, and the arrangement direction of the splicing plates intersects with the arrangement direction of the board material.

[0018] Thirdly, this utility model also provides a battery system, comprising:

[0019] Battery pack;

[0020] The protective component or the battery guard plate as described above is disposed at the bottom of the battery pack.

[0021] Fourthly, this utility model also provides a processing system suitable for processing the protective components described above, including:

[0022] The first impregnation tank and the second impregnation tank are respectively located on the running paths of the first surface layer and the second surface layer, and are respectively used to impregnate the first surface layer and the second surface layer. A clearance space is provided between the first impregnation tank and the second impregnation tank so that the core layer structure can pass through the clearance space and extend into the space between the first surface layer and the second surface layer.

[0023] A mold is used to combine the core layer structure, the first surface layer, and the second surface layer to form the protective component.

[0024] Fifthly, this utility model also provides a vehicle, including the protective component as described above, the battery guard plate as described above, the battery system as described above, or the protective component produced by the processing system as described above.

[0025] The protective component provided by this utility model forms a relatively long core layer structure by sequentially joining at least two plates. During the processing, the lengths of the first and second surface layers can be matched, reducing the impact of the core layer structure's dimensions on the processing efficiency of the protective component. This allows the core layer and surface layer to be continuously formed into the protective component, thereby improving the processing efficiency of the protective component.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] In related technologies, during the processing of protective components, a first and second surface layer need to be laminated onto both sides of a core layer. The first and second surface layers are typically rolls of material, with considerable lengths, such as up to hundreds of meters. The core layer, however, is a sheet material with limited length, such as two to three meters. Therefore, the length of the core layer is difficult to match the length of the surface layers, preventing a continuous formation of the protective component and affecting processing efficiency. Furthermore, the limited length of the core layer restricts the length of the protective component itself.

[0038] To address or improve the problem that the length of the core layer is difficult to match the length of the surface layer during the processing of protective components, this utility model provides a protective component, a battery system, a processing system, and a vehicle.

[0039] The following is combined Figures 1 to 5 The protective component 1 provided in the embodiments of this utility model is described below.

[0040] Specifically, the protective component 1 includes a plate 101, a first surface layer 102, and a second surface layer 103.

[0041] The number of plates 101 is set to at least two. At least two plates 101 are arranged sequentially and joined together along a direction perpendicular to the thickness direction of the plates 101 to form a core layer structure. For example, at least two plates 101 are arranged sequentially and joined together along a first direction, wherein the first direction is consistent with the feeding direction during the processing of the protective component. Figure 2 As shown, the first direction is Figure 2 The left and right directions in the middle.

[0042] The first surface layer 102 covers and is attached to the first side surface of the core layer structure. Optionally, refer to... Figure 1As shown, the first surface layer 102 covers and is connected to the upper surface of the core layer structure. The first surface layer 102 can be bonded or thermally fused to the core layer structure.

[0043] The second surface layer 103 covers and is attached to the second side surface of the core layer structure. Optionally, refer to... Figure 1 As shown, the second surface layer 103 covers and is attached to the lower surface of the core layer structure. Optionally, the second surface layer 103 may be bonded or thermally fused to the core layer structure.

[0044] In this embodiment, at least two plates 101 are arranged and joined in sequence to form a core layer structure. That is, a longer core layer structure is formed by splicing shorter plates 101. The relatively longer core layer structure can be adapted to the first surface layer 102 and the second surface layer 103, and the first surface layer 102 and the second surface layer 103 respectively cover the surfaces on both sides of the core layer structure to finally form the protective component 1.

[0045] With this configuration, the protective component 1 provided by this utility model forms a relatively long core layer structure by sequentially joining at least two plates 101. During the processing, the lengths of the first surface layer 102 and the second surface layer 103 can be matched, reducing the impact of the core layer structure's size on the processing efficiency of the protective component 1. This allows the core layer and surface layer to be continuously composited to form the protective component 1, thereby improving the processing efficiency of the protective component 1.

[0046] In addition, due to the increased length of the core structure, the overall length of the protective component 1 can also be longer, thus allowing for a longer protective component 1.

[0047] In some embodiments provided by this utility model, at least one of the first surface layer 102 and the second surface layer 103 includes a fiber layer, which is impregnated with adhesive and bonded to the core layer structure.

[0048] In this embodiment, at least one of the first surface layer 102 and the second surface layer 103 includes a fiber layer. The fiber layer is impregnated with resin and bonded to the core structure. Through impregnation, the fibers in the fiber layer are combined with resin, adhesive and hardener to form a composite material with higher durability and strength, thereby extending the service life of the protective component 1.

[0049] After the fiber layer is impregnated with resin and bonded to the surface of the plate 101, the structural strength of the plate 101 can be significantly improved. This is because the fiber layer is tightly bonded to the plate 101 and can jointly withstand external forces. Furthermore, the fiber layer has good tensile and compressive properties, thereby improving the tensile and compressive properties of the protective component 1. Since the fiber layer has a good effect on bearing tensile loads after impregnation, the tensile load on the plate 101 is reduced, allowing the plate 101 to mainly bear shear loads and provide supporting stiffness.

[0050] In addition, the adhesive effect can effectively reduce the relative movement between fibers in the fiber layer and reduce stress concentration caused by temperature or humidity, thereby maintaining the shape and dimensional stability of the board 101.

[0051] Optionally, the fiber layer includes, but is not limited to, fiber yarns or woven fabrics formed from glass fibers, carbon fibers, or basalt fibers. The impregnating adhesive includes, but is not limited to, polymeric materials or thermoplastic polymeric materials. The polymeric materials include, but are not limited to, composite epoxy, polyurethane, or unsaturated resins. Thermoplastic polymeric materials include, but are not limited to, polyamide, polypropylene, or polyethylene terephthalate.

[0052] Of course, the first surface layer 102 and the second surface layer 103 are not limited to including fiber layers. For example, in other embodiments provided by this utility model, at least one of the first surface layer 102 and the second surface layer 103 includes a metal layer or a plastic layer.

[0053] The metal layer, in particular, possesses high strength, providing superior protection. Metal layers include, but are not limited to, aluminum alloys and stainless steel. Aluminum alloys offer high strength, good rigidity, and corrosion resistance, while their relatively low density reduces the overall weight of the protective component. Stainless steel is a highly corrosion-resistant metal material with good strength and rigidity, thus providing excellent protective performance.

[0054] Plastic layers offer advantages such as light weight, good formability, wear resistance, and good electrical insulation, and are relatively inexpensive, making them suitable for mass production. For example, the plastic layer can be made of acrylonitrile-butadiene-styrene copolymer, polycarbonate, or polypropylene.

[0055] In some embodiments of this utility model, the plate 101 is configured with a porous structure. In this embodiment, by configuring the plate 101 with a porous structure, on the one hand, the weight of the plate 101 can be reduced, achieving the effect of lightweighting the protective component 1; on the other hand, the plate 101 can have a better heat insulation effect. For example, the protective component 1 can effectively keep the battery warm, reducing the impact of ambient temperature changes on battery performance.

[0056] Optionally, the board 101 may be made of a polymer foam material, such as polyvinyl chloride, polyurethane, or polymethacrylamide foam. Alternatively, the board 101 may also be made of wood, such as, but not limited to, balsa wood. Alternatively, the board 101 may also be made of perlite board.

[0057] Of course, the plate 101 is not limited to a porous structure. For example, in other embodiments provided by this utility model, the plate 101 is provided with weight-reducing holes. This arrangement can reduce the weight of the plate 101 and achieve the effect of making the protective component 1 lightweight. For example, the plate 101 can be a plastic plate or a metal plate.

[0058] Alternatively, the plate 101 can be configured as a hollow structure. This configuration reduces the weight of the plate 101, achieving the effect of lightweighting the protective component 1, and also provides the plate 101 with better heat insulation, enabling the protective component 1 to reduce the impact of ambient temperature changes on battery performance. For example, the plate 101 can be a plastic plate or a metal plate.

[0059] refer to Figure 2 and Figure 3 As shown, in some embodiments provided by this utility model, one of two adjacent plates 101 is provided with a first limiting part 1011, and the other is provided with a second limiting part 1012.

[0060] In the thickness direction of the plate 101, the first limiting part 1011 and the second limiting part 1012 are at least partially overlapped, so that the first limiting part 1011 and the second limiting part 1012 mutually limit each other in the thickness direction of the plate 101.

[0061] In this embodiment, in the thickness direction of the plate 101, two adjacent plates 101 are mutually limited by the first limiting part 1011 and the second limiting part 1012. The limiting effect between the first limiting part 1011 and the second limiting part 1012 can reduce the risk of loosening and falling off between the plates 101, thereby extending the service life of the protective component 1. On the other hand, it can effectively resist the displacement or deformation caused by external force, thereby significantly enhancing the connection strength between the plates 101, making the overall structure of the protective component 1 more stable, and thus providing better protection for the battery.

[0062] In addition, by limiting each other with the first limiting part 1011 and the second limiting part 1012, the plate 101 can be more easily aligned and fixed during the installation process, reducing errors and deviations during the installation process. This not only improves installation efficiency but also ensures the overall aesthetics and stability after installation.

[0063] refer to Figure 2 and Figure 3 As shown, in some embodiments provided by this utility model, the first limiting part 1011 and the second limiting part 1012 are both configured as limiting blocks.

[0064] The surface of the first limiting part 1011 facing away from the second limiting part 1012 is flush with the first side surface of the plate 101, for example, referring to... Figure 2As shown, the surface of the first limiting part 1011 that is away from the second limiting part 1012 is flush with the upper surface of the plate 101.

[0065] The surface of the second limiting part 1012 that faces away from the first limiting part 1011 is flush with the second side surface of the plate 101. For example, refer to Figure 2 As shown, the surface of the second limiting part 1012 that is away from the first limiting part 1011 is flush with the lower surface of the plate 101.

[0066] In this embodiment, the first limiting part 1011 and the second limiting part 1012 are both set as limiting blocks, and their surfaces facing away from each other are flush with the surfaces on both sides of the plate 101, which avoids gaps or unevenness caused by the protrusion or depression of the first limiting part 1011 or the second limiting part 1012. This makes the overall appearance of the core layer structure cleaner and more uniform, without any protruding parts, reducing interference and snagging problems, and avoiding wear caused by friction between the protruding parts and the surrounding environment, thus extending the service life of the protective part 1.

[0067] refer to Figure 3 As shown, in some embodiments provided by this utility model, a first limiting part 1011 is provided at one end of the plate 101, and a second limiting part 1012 is provided at the other end of the plate 101.

[0068] In this embodiment, reference is made to Figure 2 As shown, by setting a first limiting part 1011 at one end of the plate 101 and a second limiting part 1012 at the other end of the plate 101, after all the plates 101 are connected in sequence, the plate 101 is limited in both the upper and lower directions.

[0069] Through this limiting design, the plates 101 form a mutually supporting and constraining overall structure. In this structure, each plate 101 bears a certain stress and load, and the stress and load are transferred to adjacent plates 101 through the limiting parts. This method of stress transfer and dispersion makes the core layer structure more stable and durable. Even if a plate 101 is subjected to a large external force, it can resist and disperse these forces through the support and limiting effect of adjacent plates 101, thereby maintaining the stability and safety of the overall structure.

[0070] In addition, since the plate 101 is constrained in both the vertical and horizontal directions, it is less likely to deform or displace when subjected to external forces, thereby improving the overall strength of the core structure and thus enhancing its protective performance.

[0071] refer to Figure 3 As shown, in some embodiments provided by this utility model, the first limiting part 1011 and the second limiting part 1012 are both formed by milling, for example... Figure 3 As shown, a first step structure is milled at the first end of the plate 101 to form a first limiting part 1011, and a second step structure is milled at the second end of the plate 101 to form a second limiting part 1012.

[0072] Of course, the first limiting part 1011 and the second limiting part 1012 are not limited to being formed by milling. For example, in other embodiments provided by this utility model, the first limiting part 1011 and the second limiting part 1012 can form an integral structure with the plate 101. Optionally, the first limiting part 1011, the second limiting part 1012 and the plate 101 can be formed by, but not limited to, extrusion molding, injection molding, blow molding, hot pressing, vacuum molding, casting molding or foaming molding.

[0073] It is understood that the first limiting part 1011 and the second limiting part 1012 are not limited to both being limiting blocks. For example, in other embodiments provided by this utility model, one of the first limiting part 1011 and the second limiting part 1012 is a limiting block, and the other is a limiting recess into which the limiting block can be inserted. Optionally, the limiting recess can be a limiting groove or a limiting hole provided on the end face of the plate 101.

[0074] In this embodiment, by setting one of the first limiting part 1011 and the second limiting part 1012 as a limiting block and the other as a limiting recess, after the limiting block and the limiting recess are connected, the first limiting part 1011 and the second limiting part 1012 can limit each other in both the up and down directions.

[0075] Through the mutual restraint of the limiting blocks and recesses, the plates 101 can form a mutually supporting and constraining overall structure. In this structure, each plate 101 bears a certain stress and load, and the stress and load are transferred to the adjacent plates 101 through the limiting parts. This method of stress transfer and dispersion makes the core structure more stable and durable. Even if a plate 101 is subjected to a large external force, it can resist and disperse these forces through the support and restraint of the adjacent plates 101, thereby maintaining the stability and safety of the overall structure.

[0076] In addition, since the plate 101 is constrained in both the vertical and horizontal directions, it is less likely to deform or displace when subjected to external forces, thereby improving the overall strength of the core structure and thus enhancing the protective performance of the protective component 1.

[0077] Furthermore, a limiting block is provided at the first end of the plate 101, and a limiting recess is provided at the second end of the plate 101. This arrangement ensures that each plate 101 has the same shape, thereby reducing the processing difficulty of the plate 101.

[0078] In some embodiments provided by this utility model, the protective member 1 further includes a positioning member. Optionally, the positioning member may be a positioning pin or a positioning rod.

[0079] At the joint of two adjacent plates 101, the positioning member passes through the first limiting part 1011 and the second limiting part 1012 along the thickness direction of the plate 101. Specifically, if both the first limiting part 1011 and the second limiting part 1012 are configured as limiting blocks, positioning holes 104 can be provided on both the first limiting part 1011 and the second limiting part 1012. The positioning member then passes through the positioning holes 104 of both the first limiting part 1011 and the second limiting part 1012 in sequence, thereby positioning and connecting the first limiting part 1011 and the second limiting part 1012 in a direction perpendicular to the thickness direction of the plate 101. If one of the first limiting part 1011 and the second limiting part 1012 is configured as a limiting block and the other as a positioning recess, the positioning member passes through the first sidewall of the positioning recess, the positioning block, and the second sidewall of the positioning recess in sequence, thereby pin-connecting the first limiting part 1011 and the second limiting part 1012.

[0080] In this embodiment, the positioning member passes through the first limiting part 1011 and the second limiting part 1012 in sequence. The positioning member can limit the first limiting part 1011 and the second limiting part 1012 in a direction perpendicular to the thickness direction of the plate 101, preventing the first limiting part 1011 and the second limiting part 1012 from separating, thereby increasing the connection strength of the first limiting part 1011 and the second limiting part 1012, and thus improving the overall strength and tensile performance of the core layer structure.

[0081] Optionally, the positioning element is bonded to the first limiting part 1011 and the second limiting part 1012 respectively with adhesive, thereby improving the stability of the positioning element and preventing the positioning element from detaching from the first limiting part 1011 or the second limiting part 1012. Furthermore, the adhesive used for impregnating the fiber layer, the adhesive used for the positioning element, and the positioning element itself are all made of the same material to avoid harmful reactions between them that could lead to failure.

[0082] Optionally, at the joint of two adjacent plates 101, the first limiting part 1011 and the second limiting part 1012 are positioned against each other by at least two positioning members. This arrangement can improve the connection strength and positioning effect between the first limiting part 1011 and the second limiting part 1012, and also prevent relative rotation between the first limiting part 1011 and the second limiting part 1012 about the positioning member axis, thereby improving the overall stability of the core layer structure.

[0083] In some embodiments provided by this utility model, in the core layer structure, at least one plate 101 is made of a different material than the other plates 101.

[0084] In this embodiment, by using different materials for the plates 101 at different locations, different scenarios with varying requirements for the protective component can be addressed. For example, when the protective component 1 is applied to the side wall of a laboratory, a portion of the protective component 1 is used to enclose a chamber for housing the testing equipment, and another portion is used to enclose a chamber for personnel to observe and record locations. In this case, the portion of the protective component 1 used to house the testing equipment uses plate 101 that meets the testing requirements, such as radiation protection, heat insulation, or sound insulation, while the remaining portion can use ordinary plate to reduce costs.

[0085] In addition, by making the materials of the plates 101 in different positions different, and then dividing the protective parts 1 according to actual needs, products of various materials can be formed at one time.

[0086] In some embodiments of this utility model, the plate 101 includes at least two splicing plates. Along a direction perpendicular to the thickness direction of the plate 101, at least two splicing plates are arranged sequentially and joined together, and the arrangement direction of the splicing plates intersects with the arrangement direction of the plate 101. For example, the arrangement direction of the splicing plates is a second direction, and the arrangement direction of the plate 101 is a first direction; the second direction intersects with the first direction, for example, they are perpendicular.

[0087] In this embodiment, the board 101 includes at least two splicing boards arranged and joined in sequence. By joining at least two splicing boards in sequence, the size of the core layer structure can be increased in the direction intersecting with the arrangement direction of the board 101.

[0088] Furthermore, in at least two of the splicing plates of the sheet 101, at least one splicing plate is made of a different material than the other splicing plates. In this embodiment, by using different materials for the sheet 101 at different locations, scenarios with different requirements for different locations of the protective component can be addressed. In addition, by using different materials for the sheet 101 at different locations, products made of multiple different materials can be molded in one step.

[0089] Optionally, at least two splicing plates of the plate 101 can be connected by adhesive bonding or by a structural connection that is the same as the connection structure between the plates 101.

[0090] Optionally, in at least two splicing panels of the board 101, the two adjacent splicing panels are arranged at an angle.

[0091] For example, plate 101 includes two splicing plates connected to form an L-shaped structure, which facilitates the fabrication of L-shaped protective components. For instance, the L-shaped protective component can serve as a side beam of a battery box. Of course, plate 101 can also be formed by connecting two or more splicing plates to create an L-shaped structure.

[0092] Alternatively, plate 101 may include three splicing plates connected to form a U-shaped structure, facilitating the fabrication of U-shaped protective components. For example, U-shaped protective components can be used to form the main body of a battery box. Of course, plate 101 may also be formed by connecting more than three splicing plates to create a U-shaped structure.

[0093] Alternatively, panel 101 may include four splicing panels connected end-to-end to form a U-shaped structure, facilitating the fabrication of U-shaped protective components. For example, U-shaped protective components can be directly used as the main body of a laboratory, a freight car body, or a rail vehicle body. Of course, panel 101 can also be formed by connecting four or more splicing panels to create a U-shaped structure.

[0094] This utility model also provides a battery protection plate.

[0095] Specifically, the battery protection plate is formed by dividing the protective component 1 as described above.

[0096] It should be noted that the battery protection plate provided by this utility model includes the protective component 1, and therefore also includes all the advantages of the protective component 1 mentioned above, so it will not be described in detail here.

[0097] Alternatively, the protective components are not limited to battery guards. For example, battery guards can also be used in battery pack housings, van bodies, rail vehicle roofs or floor panels, road noise barriers, or laboratory partitions or exterior walls.

[0098] This utility model also provides a battery system.

[0099] Specifically, the battery system includes a battery pack and a protective element 1 as described above. The protective element 1 is disposed at the bottom of the battery pack. Alternatively, the battery system includes a battery pack and a battery guard plate as described above, with the battery guard plate disposed at the bottom of the battery pack.

[0100] It should be noted that the battery system provided by this utility model includes the protective component 1, and therefore also includes all the advantages of the protective component 1 mentioned above, so it will not be described in detail here.

[0101] refer to Figure 5 As shown, this utility model embodiment also provides a processing system.

[0102] Specifically, the machining system is suitable for machining the protective component 1 as described above.

[0103] The processing system includes a first impregnation tank 2, a second impregnation tank 3, and a mold 5.

[0104] The first impregnation tank 2 and the second impregnation tank 3 are respectively located on the running paths of the first surface layer 102 and the second surface layer 103, and are used to impregnate the first surface layer 102 and the second surface layer 103. A clearance space 4 is provided between the first impregnation tank 2 and the second impregnation tank 3 so that the core layer structure can pass through the clearance space 4 and extend between the first surface layer 102 and the second surface layer 103. For example, the first impregnation tank 2 and the second impregnation tank 3 are arranged in a vertical direction. For example, both the first surface layer 102 and the second surface layer 103 include a fiber layer.

[0105] The mold 5 is used to composite the core layer structure, the first surface layer 102, and the second surface layer 103 to form the protective component 1. For example, the mold 5 can be configured as a pultrusion mold or a compression mold.

[0106] In this embodiment, during processing, the first surface layer 102 and the second surface layer 103 are impregnated with resin in the first impregnation tank 2 and the second impregnation tank 3, respectively. The core layer structure extends into the space between the first surface layer 102 and the second surface layer 103 through the clearance space 4 between the first impregnation tank 2 and the second impregnation tank 3. The core layer structure, the first surface layer 102, and the second surface layer 103 simultaneously enter the mold 5, and are composited into the protective component 1 through processes such as pultrusion or molding within the mold 5.

[0107] With this configuration, the processing system can combine the core layer structure formed by butt jointing of the sheet metal 101, the first surface layer 102, and the second surface layer 103 to form the protective component 1, and the processing system has a simple structure.

[0108] In some embodiments provided by this utility model, the mold 5 is configured as a pultrusion mold. The processing system also includes a traction mechanism 6, which is located downstream of the mold 5. The traction mechanism 6 is used to connect with the protective member 1 to drive the protective member 1 out of the mold 5.

[0109] In this embodiment, the traction mechanism 6 can continuously drive the protective component 1 out of the pultrusion die 5 so that the pultrusion die 5 can continuously composite the core layer structure, the first surface layer 102 and the second surface layer 103 to form the protective component 1, thereby improving the production efficiency of the protective component 1.

[0110] Optionally, the traction mechanism 6 includes, but is not limited to, tracked traction devices and alternating reciprocating traction systems.

[0111] In some embodiments provided by this utility model, the processing system further includes a first unwinding roller 8 and a second unwinding roller 9. The first unwinding roller 8 and the second unwinding roller 9 are respectively wound with a first surface layer 102 and a second surface layer 103. During the processing, the first unwinding roller 8 and the second unwinding roller 9 are respectively used to unwind the first surface layer 102 and the second surface layer 103.

[0112] In some embodiments of this invention, the processing system further includes a cutting device 7, which is used to cut the protective member 1. In this embodiment, the protective member 1 is cut by the cutting device 7 to make the protective member 1 into a suitable size. For example, the protective member 1 can be cut by the cutting device 7 to form a battery guard plate.

[0113] This utility model also provides a vehicle in its embodiments.

[0114] Specifically, the vehicle includes the protective component 1 as described above, the battery shield as described above, the battery system as described above, or the protective component 1 produced by the processing system as described above.

[0115] It should be noted that the vehicle includes protective component 1, and therefore includes all the advantages of protective component 1 mentioned above.

[0116] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
