That is to say, the aluminum plate has the function of shielding the electromagnetic field. In the prior art, the aluminum plate and the disk frame can be bonded by adhesive. Although the cost is low, in the process of producing the coil disk, a clamp needs to be designed to position the aluminum plate. The clamp for fixing the aluminum plate can be removed only after the adhesive is dry. Moreover, since the curing time of the adhesive is long, the working hours are long and the process is cumbersome, which affects the production efficiency. The buckle structure can be stamped on the aluminum plate, but the required mold structure is relatively complex, and the aluminum plate must be at least 1mm thick to make the buckle structure have sufficient strength, which is not conducive to reducing costs.

[0023] The utility model is further described below in conjunction with the accompanying drawings.

[0024] The utility model of the heat riveting type coil disk aluminum plate fixing structure, such as Figure 1 and Figure 2 As shown, it includes an aluminum plate 1 and a rack 2, the rack 2 includes a rack body 20, the aluminum plate 1 is attached to the rack body 20, specifically, the upper part of the rack body 20 is formed with a plane for attaching to the aluminum plate 1, the coil 3 is wound on the rack 2, and for the convenience of display, Figure 1 In the figure, the coil 3 is located directly below the aluminum plate 1, but in actual application, it is necessary to Figure 1 The structure is shown upside down.

[0025] like Figure 3 As shown, the aluminum plate 1 is formed with a buckled edge portion 100, such as Figure 4 As shown, a protrusion structure is formed on the rack body 20. In other words, the protrusion structure and the rack body 20 are integrated. Figure 7 and Figure 8 As shown, the raised structure is attached to and connected with the corresponding buckling edge portion 100 , that is, in the horizontal direction, the raised structure and the corresponding buckling edge portion 100 are attached to each other, and a hot riveting flange 200 is formed at the upper end of the raised structure, and the hot riveting flange 200 is buckled to the upper side of the corresponding buckling edge portion 100 .

[0026] In the process of assembling the aluminum plate 1 and the tray frame 2, as shown in FIG. Figure 5 As shown, the aluminum plate 1 is aligned with the rack 2, and then the aluminum plate 1 is moved downward and abutted against the rack body 20, as shown in FIG. Figure 6 As shown, at this time, the above-mentioned raised structure is horizontally attached to the corresponding buckled edge portion 100, that is, the above-mentioned raised structure has a blocking and positioning effect on the aluminum plate 1 in the horizontal direction. Then, the hot pressing mold 99 is pressed down to the upper end of the above-mentioned raised structure, and the heat of the hot pressing mold 99 is transferred to the upper end of the above-mentioned raised structure, so that the upper end of the above-mentioned raised structure is quickly heated and softened. Since the hot pressing mold 99 applies downward pressure to the upper end of the above-mentioned raised structure, as shown in FIG. Figure 7As shown, the upper end of the above-mentioned raised structure is also collapsed and squeezed by the hot pressing mold 99 to form a hot riveting flange 200, and the hot riveting flange 200 is buckled on the upper side of the corresponding buckling edge portion 100, and then the hot pressing mold 99 rises and leaves the aluminum plate 1 and the disc frame 2, and the hot riveting flange 200 is cooled and solidified at a relatively fast speed. A blowing structure can be set to further accelerate the cooling of the hot riveting flange 200, so that the hot riveting flange 200 and the corresponding buckling edge portion 100 are buckled with higher strength, that is, the aluminum plate 1 is sandwiched between the disc frame body 20 and the hot riveting flange 200, so that the aluminum plate 1 and the disc frame 2 are relatively fixed in the vertical direction. As can be seen from the above, the assembly of the aluminum plate 1 and the disc frame 2 of the utility model avoids the need to use adhesives, avoids the need to wait for the adhesive to dry for a long time, is conducive to improving the production efficiency of the coil disc, and avoids the smell of the adhesive from polluting the air in the workshop, and also avoids the trouble of storing the adhesive. Since the buckle structure is formed on the disc frame 2 by hot riveting in the utility model, it is not necessary to stamp the buckle structure on the aluminum plate 1, so that the thickness of the aluminum plate 1 can be set smaller, which is conducive to reducing costs.

[0027] As further shown, Figure 3 As shown, a through hole 101 is formed on the aluminum plate 1, and the through hole 101 is provided with a buckle edge portion 100. In other words, the edge of the through hole 101 includes the buckle edge portion 100. Furthermore, the edge of the through hole 101 is a ring structure formed by integrally connecting the buckle edge portion 100, such as Figure 4 As shown, a convex column 201 is formed on the rack body 20, and the convex column 201 includes the above-mentioned convex structure. Furthermore, the convex column 201 is a columnar structure formed by integrally connecting the above-mentioned convex structure, such as Figure 1 and Figure 7 As shown, the boss 201 is adapted to pass through the through hole 101, so that the movement of the aluminum plate 1 in all directions in the horizontal plane will be blocked by the boss 201, which is conducive to enhancing the positioning effect of the rack 2 on the aluminum plate 1, further avoiding the displacement of the aluminum plate 1 during the hot riveting process, and is conducive to the accurate position of the aluminum plate 1 relative to the rack 2. If the edge of the through hole 101 is a buckle edge portion 100 all around, then correspondingly, the upper end of the boss 201 also forms a hot riveting flange 200 all around, which is conducive to enhancing the riveting strength.

[0028] Furthermore, if Figure 4 As shown, the boss 201 is configured to be cylindrical, so that the amount of material that needs to be heated to a softened state when the boss 201 contacts the hot pressing die 99 is greatly reduced without significantly reducing the structural strength of the boss 201. Therefore, the required heat and time are greatly reduced. In addition, the lower structural strength of the upper end of the boss 201 also makes it easier to be collapsed by the hot pressing die 99, thereby facilitating the rapid forming of the hot riveting flange 200.

[0029] Furthermore, if Figure 4 As shown, the number of the bosses 201 is set to at least two, so the rotation of the aluminum plate 1 relative to the disc rack 2 in the horizontal plane will be directly blocked by the bosses 201, that is, at least two bosses 201 block the rotation of the aluminum plate 1, combined with the snap-fit ​​effect of the hot riveted flange 200, the aluminum plate 1 and the disc rack 2 are further fixed more reliably.

[0030] Furthermore, if Figure 3 As shown, a notch 102 is formed on the periphery of the aluminum plate 1, that is, the notch 102 is located outside the through hole 101, and the notch 102 is provided with a buckle edge portion 100, that is, the edge of the notch 102 includes the buckle edge portion 100, as shown in FIG. Figure 4 As shown, a convex shell 202 is formed on the periphery of the rack body 20. The convex shell 202 includes the above-mentioned convex structure. The convex shell 202 is connected with the notch 102 in an adaptive manner. More specifically, the convex shell 202 is a shell-like structure formed by integrally connecting the above-mentioned convex structure. Since the convex shell 202 is distributed circumferentially and the convex shell 202 is connected with the notch 102 in an adaptive manner, the aluminum plate 1 is further prevented from rotating or moving relative to the rack 2. Since the convex shell 202 includes the convex structure, that is, the upper end of the convex shell 202 is also formed with a hot riveted flange 200 that is fastened to the notch 102. The fastening edge portion 100 prevents the aluminum plate 1 from warping at the peripheral edge, making the aluminum plate 1 more reliably fixed. Further, as Figure 4 As shown, the notch 102 is set to be in an arc shape, so accordingly, the top view shape of the convex shell 202 is in an arc shape, and the convex shell 202 is roughly half of the cylindrical structure. Since the thickness of the aluminum plate 1 is relatively small, but the notch 102 is set to be in an arc shape, it is avoided that the notch 102 forms a sharp inner angle and causes tearing.

[0031] Furthermore, if Figure 4 As shown, the notches 102 are evenly distributed in the circumferential direction, which is beneficial for uniform force on the edge of the aluminum plate 1. Specifically, the number of the notches 102 and the convex shells 202 can be set to four.

[0032] Furthermore, if Figure 5 As shown, the convex shell 202 and the convex column 201 are arranged at the same height, that is, the upper end of the convex shell 202 and the upper end of the convex column 201 are located in the same horizontal plane. Therefore, when the hot pressing mold 99 performs the hot pressing riveting process, it is helpful to simplify the movement path of the hot pressing mold 99. For example, the hot pressing mold 99 can be raised after processing the convex column 201, and the hot pressing mold 99 is translated to the corresponding position of the convex shell 202. The hot pressing mold 99 is lowered to the same height, and the hot pressing riveting process of the convex shell 202 can be correctly completed; an integral hot pressing mold 99 can be used to perform the hot pressing riveting process on all convex shells 202 and all convex columns 201 at one time to improve production efficiency.
