[0036] This disclosure provides a vehicle that may include a body on which an extension device can be detachably installed. The extension device may be a Bluetooth button, a glasses case, an ambient light, etc. To facilitate installation and removal, and to simplify the structure and reduce costs, the extension device can be secured using a magnetic structure. The magnetic structure can be located on the roof, the center console, seats, armrests, etc., and its location is not specifically limited herein.

[0037] like Figures 1-4 As shown, this disclosure provides a magnetic attraction structure 1a, which may include a substrate 1, a fixing member 2, and a magnetic attraction assembly 3, wherein:

[0038] The fixing member 2 can be stacked on one side of the substrate 1 and fixedly connected to the substrate 1. The magnetic suction assembly 3 can be disposed on the side of the substrate 1 close to the fixing member 2. At the same time, the magnetic suction assembly 3 can include a base 31 and a magnetic suction member 32. The base 31 is connected to the fixing member 2, and the magnetic suction member 32 is fixed to the base 31; the magnetic suction member 32 is used to attract the extension device.

[0039] The magnetic attraction structure of this embodiment can fix at least one of its substrate 1 and fixing member 2 to a vehicle. Simultaneously, the magnetic attraction member 32 can be fixed to the fixing member 2 via the base 31. An external extension device can be equipped with magnetic elements, which can be attracted to the magnetic attraction member 32, thus attaching the extension device to the vehicle. Since the magnetic attraction method does not require a mechanical structure to connect the extension device and the substrate 1, it improves the efficiency of installation and disassembly, simplifies the structure, and reduces production costs.

[0040] Magnetic structures can be fixed to any supporting structure within the vehicle body, or they can be integrated into the vehicle body itself. For example, the vehicle body may have a roof structure with occupants positioned beneath it. The roof structure can include a roof cover and a headliner fixed to the roof cover, located inside the roof cover, i.e., closer to the vehicle interior and the occupants. The headliner serves both a decorative purpose and can be used to secure extension devices. The magnetic structure can be integrated into the headliner, forming a headliner with magnetic functionality.

[0041] The following is a detailed explanation using the magnetic structure located in the top liner as an example:

[0042] likeFigure 2 and Figure 4 As shown, substrate 1 can cover the inner side of the top cover for decorating the top of the vehicle interior. Substrate 1 can adopt a stacked multi-layer structure. For example, in some embodiments of this disclosure, substrate 1 can include a stacked base layer 11 and a surface layer 12, wherein the base layer 11 can face the top cover, and the surface layer 12 covers the side of the base layer 11 away from the top cover. The base layer 11 can be a multi-layer structure, and its material can include materials such as PP (polypropylene) and PU (polyurethane). The surface layer 12 can also be a multi-layer structure, and its material can include non-woven fabric, foam, etc.

[0043] Of course, in other embodiments of this disclosure, the base layer 11 and the surface layer 12 may also be single-layer structures, or the substrate 1 may also be a single-layer structure.

[0044] like Figures 2-4 As shown, the fastener 2 can be fixed to the side of the substrate 1 near the top cover and can be connected to the top cover; of course, the fastener 2 can also be fixed to the top cover only, based on the fixed connection between the substrate 1 and the top cover; or, the fastener 2 and the substrate 1 can be fixed to the top cover simultaneously; that is, at least one of the substrate 1 and the fastener 2 is fixed to the top cover. The connection method between the fastener 2 and the substrate 1 and the top cover can be adhesive, riveting, or using threaded connections, etc., and no special limitation is made here.

[0045] In some embodiments of this disclosure, the fastener 2 may include a flat plate portion 21 stacked on the substrate 1, which can be attached to the substrate 1 and extends along the extension direction of the substrate 1; for example, the flat plate portion 21 can be bonded to the base layer 11 of the substrate 1 by an adhesive; further, the flat plate portion 21 may be provided with an overflow hole 22, which can penetrate the flat plate portion 21 in a direction perpendicular to the substrate 1, and the adhesive bonding the flat plate portion 21 and the base layer 11 can overflow from the overflow hole 22, that is, fill the overflow hole 22.

[0046] like Figures 2-4 As shown, the magnetic suction component 3 can be disposed on the side of the substrate 1 near the fixing member 2. After the substrate 1 is fixed to the top cover, the magnetic suction component 3 is covered between the substrate 1 and the top cover. The magnetic suction component 3 can be used to adsorb the extension device. By using the principle of attraction between opposite poles, the extension device can be fixed, thus eliminating the need for a special connection structure to connect through snap-fit, threaded connection or other methods. The installation and disassembly efficiency is high, and the structure is simple.

[0047] The magnetic assembly 3 may include a base 31 and a magnetic element 32. The base 31 can be fixed to the fixing element 2 by means of snap-fit, adhesive, or threaded connection. Alternatively, the base 31 can be integrally formed with the fixing element 2 to create a single structure. The magnetic element 32 is fixed to the base 31 by means of snap-fit ​​or adhesive. Thus, the magnetic element 32 can be fixed to the fixing element 2 via the base 31, and subsequently to the substrate 1 and the top cover. The number of magnetic assemblies 3 can be one, two, or more, all of which are fixedly connected to the fixing element 2, thereby attracting multiple extension devices. Of course, other non-magnetic connection structures can also be provided on the fixing element 2 to connect with some extension devices by means of snap-fit ​​or other methods.

[0048] The magnetic attractor 32 can attract magnetic elements of the extension device based on the principle of magnetic attraction. For example, at least one of the magnetic attractor 32 and the magnetic attractor element can be a permanent magnet, and the other can be a permanent magnet or a ferromagnetic material, so that only the two can be magnetically attracted.

[0049] The magnetic attractor 32 may be a flat plate structure, which may include two surfaces distributed along a direction away from the substrate 1 and an outer peripheral surface surrounding the surface. The outline of the outer peripheral surface may be a rectangle or other polygons, or it may be a circle, an ellipse, or an oval, etc. There is no special limitation on its shape here.

[0050] The following is a detailed description of the scheme for fixing the magnetic component 32 via the base 31:

[0051] In some embodiments of this disclosure, the base 31 may include a base plate 311 and a clamping portion, wherein:

[0052] like Figures 2-4 As shown, the base plate 311 can be fixedly connected to the fastener 2, thereby fixing the base 31 to the fastener 2; for example, the base plate 311 can be fixedly connected to the edge of the flat plate portion 21 of the fastener 2, and the two can adopt an integral structure, so that they can be integrally molded, that is, the base plate 311 can be regarded as a part extending outward from the flat plate portion 21. Of course, the base plate 311 can also be fixedly connected to the flat plate portion 21 by means of bonding, snap-fitting, etc.

[0053] The clamping parts are at least two in number, each fixed to the base plate 311 and distributed circumferentially along the base plate 311, that is, spaced apart along the extension direction of the outer circumferential surface of the base plate 311. Simultaneously, each clamping part can extend towards the substrate 1, that is, protrude from the base plate 311. The magnetic suction member 32 can be confined within the area surrounded by each clamping part, thereby limiting its position through multiple clamping parts and preventing it from loosening; and because there are gaps between the clamping parts, the magnetic suction member 32 can be disassembled for easy maintenance.

[0054] The clamping part and the base plate 311 can be an integral structure, which can be integrally molded, which is beneficial to simplify the process and structure. Of course, this disclosure does not exclude the possibility that the clamping part and the base plate 311 can be connected by snap-fit, adhesive or other independent structures.

[0055] Furthermore, such as Figures 2-4 As shown, in some embodiments of this disclosure, each clamping part may include a plurality of first clamping parts 312 and second clamping parts 313, that is, at least two first clamping parts 312 and at least two second clamping parts 313; each first clamping part 312 and second clamping part 313 may be alternately distributed along the circumference of the base plate 311, that is, in the circumference of the base plate 311, one of two adjacent clamping parts is a first clamping part 312 and the other is a second clamping part 313.

[0056] The first clamping portion 312 may include a connecting section 3121 and a defining section 3122 distributed toward the substrate 1, wherein:

[0057] One end of the connecting segment 3121 can be connected to the base plate 311, and the other end can extend toward the substrate 1. The connecting segments 3121 of each first clamping part 312 can be distributed circumferentially along the substrate 1. The limiting segment 3122 is connected to the end of the connecting segment 3121 near the substrate 1, and the limiting segment 3122 of any first clamping part 312 can extend into the area surrounded by its connecting segment 3121, so that the limiting segment 3122 and the connecting segment 3121 can form a hook-shaped structure that bends toward the inside of the base plate 311. For example, if there are two first clamping parts 312, and the connecting segments 3121 of the two first clamping parts 312 are distributed on both sides of the center of the base plate 311, then the limiting segments 3122 of the two first clamping parts 312 can extend toward each other or toward the center of the base plate 311, as long as the above-mentioned hook-shaped structure can be formed.

[0058] The magnetic suction member 32 can be confined between the limiting section 3122 and the base plate 311. The limiting section 3122 can support the magnetic suction member 32 and prevent it from falling onto the substrate 1, while the connecting section 3121 can block the magnetic suction member 32 in the circumferential direction to prevent it from falling off in a direction parallel to the substrate 1. Thus, the magnetic suction member 32 can be confined by the first clamping part 312. At the same time, the second clamping part 313 can also work together with the connecting section 3121 of the first clamping part 312 to block the magnetic suction member 32 in the circumferential direction to prevent it from falling off in a direction parallel to the substrate 1.

[0059] When disassembling the magnetic chuck 32, an external force can be applied to the first clamping part 312 outside its surrounding area to move the limiting section 3122 to the outside of the magnetic chuck 32 and disengage it, and then the magnetic chuck 32 can be removed. To facilitate disassembly, the first clamping part 312 can be made of a material or structure with a certain degree of elasticity.

[0060] likeFigure 3 As shown, in some embodiments of this disclosure, the second clamping part 313 may be a protruding ridge protruding from the base plate 311. The surface of the second clamping part 313 near the magnetic member 32 may contact the outer peripheral surface of the magnetic member 32, and the shape of the surface of the second clamping part 313 near the magnetic member 32 may match and fit the outer peripheral surface of the magnetic member 32. For example, if the outline of the outer peripheral surface of the magnetic member 32 is circular, then the surface of the second clamping part 313 near the magnetic member 32 may be an arc surface.

[0061] The thickness of the second clamping portion 313 in the direction perpendicular to the substrate 1 can be less than the thickness of the first clamping portion 312. For example, for the first clamping portion 312, which includes a connecting section 3121 and a defining section 3122, the height of the connecting section 3121 in the direction perpendicular to the substrate 1 is greater than the thickness of the second clamping portion 313. The second clamping portion 313 is thinner than the first clamping portion 312, which reduces the contact surface with the magnetic suction member 32 without affecting the limiting function, thus facilitating the installation and removal of the magnetic suction member 32.

[0062] Furthermore, the thickness of the second clamping part 313 in the direction perpendicular to the substrate 1 can be made smaller than the thickness of the magnetic suction member 32, which can further reduce the contact area between the second clamping part 313 and the magnetic suction member 32, so as to facilitate the installation and removal of the magnetic suction member 32.

[0063] Furthermore, in some embodiments of this disclosure, each clamping part may include only the first clamping part 312 described above, and the magnetic suction member 32 is fixed only through a plurality of first clamping parts 312; in other embodiments of this disclosure, each clamping part may include only the second clamping part 313 described above, and the magnetic suction member 32 is fixed only through a plurality of second clamping parts 313.

[0064] like Figures 2-4 As shown, in some embodiments of this disclosure, in order to reduce the thickness of the magnetic absorbing assembly 3 in the direction perpendicular to the substrate 1 and thus reduce the space occupied, the thickness of the base plate 311 can be less than the thickness of the flat plate portion 21. The surface of the base plate 311 away from the substrate 1 and the surface of the flat plate portion 21 away from the substrate 1 are coplanar, such that the surface of the base plate 311 near the substrate 1 is located on the side of the surface of the flat plate portion 21 near the substrate 1 away from the substrate 1, thereby forming a space that can accommodate a portion of the magnetic absorbing member 32.

[0065] like Figures 2-4As shown, in some embodiments of this disclosure, a clearance hole 111 may be formed in the base layer 11 of the substrate 1 in the region corresponding to at least a portion of the first clamping portion 312. The clearance hole 111 is a through hole penetrating the base layer 11. The first clamping portion 312 can pass through the clearance hole 111 and can contact the surface layer 12. The shape of the clearance hole 111 may match the shape of the end of the first clamping portion 312 away from the base plate 311. For example, the shape of the clearance hole 111 may be the same as the shape of the limiting segment 3122, and the limiting segment 3122 may be placed inside the clearance hole 111. The thickness of the limiting segment 3122 may be the same as the thickness of the base layer 11, so as to be flush with the surface of the base layer 11. Of course, the thickness of the limiting segment 3122 may also be less than or greater than the thickness of the base layer 11.

[0066] For the multiple first clamping parts 312, if the base layer 11 is provided with clearance holes 111 in the area corresponding to each first clamping part 312 and is distributed at intervals along the circumference of the base plate 311, then the clearance holes 111 are also distributed at intervals along the circumference of the base plate 311. The multiple clearance holes 111 can be distributed around an area in the base layer 11, and this area can be attached to the surface of the magnetic suction member 32 near the substrate 1, which can play the role of supporting the magnetic suction member 32.

[0067] Furthermore, such as Figures 2-4 As shown, the thickness of the area of ​​the base layer 11 that is in contact with the magnetic member 32 can be less than the thickness of at least a portion of the area that is not in contact with the magnetic member 32. This allows a portion of the magnetic member 32 to be embedded in the base layer 11, reducing the overall thickness. This facilitates increasing the thickness of the magnetic member 32 without increasing the overall thickness, thereby enhancing its magnetism. In some embodiments, the thickness of the area of ​​the base layer 11 in contact with the magnetic member 32 can be 1mm-1.5mm, while the thickness of the area that is not in contact with the magnetic member 32 is greater than 1.5mm. For example, the thickness of the area of ​​the base layer 11 that is not in contact with the magnetic member 32 can be 2mm.

[0068] For example, such as Figure 2 and Figure 4 As shown, in some embodiments, the base layer 11 of the substrate 1 has a recess 112 that is recessed into the surface layer 12, and the recess 112 does not penetrate the base layer 11; the clearance hole 111 is at least partially formed in the recess 112; the magnetic member 32 is attached to the bottom surface of the recess 112, and the area of ​​the base layer 11 that is not attached to the magnetic member 32 is located outside the recess 112 and has a thickness greater than the thickness of the bottom S1 of the recess 112, so that the thickness of the area of ​​the base layer 11 that is attached to the magnetic member 32 is greater than the thickness of the area that is not attached to the magnetic member 32.

[0069] The thickness of the magnetic accumulator 32 can be greater than the thickness of the base layer 11 and greater than the depth of the recess 112 to ensure sufficient magnetism; of course, the thickness of the magnetic accumulator 32 can also be equal to the depth of the recess 112 so as to be embedded in the base layer 11, which is beneficial to keep the substrate 1 flat.

[0070] Furthermore, the thickness of the second clamping part 313 in the direction perpendicular to the substrate 1 is not greater than the depth of the pit 112, and the second clamping part 313 can extend into the pit 112 without raising the base layer 11 and the substrate 1, which is beneficial to keeping the substrate 1 flat.

[0071] In some embodiments of this disclosure, such as Figure 1 As shown, the magnetic structure 1a may have an indicator mark 4 to indicate the position of the adsorption extension device to the driver or passenger. For example, the indicator mark 4 may be provided on the surface of the substrate 1 away from the fixing member 2 in the area corresponding to the magnetic member 32; furthermore, the indicator mark 4 may be a pattern formed on the surface of the surface layer 12 of the substrate 1 away from the base layer 11. The pattern may be formed by an uneven structure or by painting with pigments. The pattern may be text, geometric shapes or other shapes.

[0072] This disclosure provides a vehicle roof structure, which may include a roof cover and a roof liner. The roof cover is located on top of the vehicle body and may be an integral structure with the vehicle body, or it may be an independent structure fixedly connected by welding or other methods. The roof cover may be a continuous, integral structure, or it may have a sunroof. The roof liner has a perforation in the area corresponding to the sunroof.

[0073] The top cover can adopt the magnetic suction structure of any of the above embodiments, and the structure of the top cover will not be described in detail here; wherein, at least one of the fixing member 2 and the substrate 1 is fixedly connected to the top cover, and the fixing member 2 is located between the top cover and the substrate 1, thereby fixing the magnetic suction structure on the top cover.

[0074] This disclosure provides a vehicle body that may include the roof structure described above.

[0075] This disclosure also provides a vehicle, which may include a body with a passenger compartment and engine compartment formed within it.
