Specific embodiments
[0023] The present utility model will be further described below with reference to the accompanying drawings.
[0024] The snap-fastening type coil disk aluminum plate fixing structure of the present utility model, as Figures 1 to 3 shown, includes an aluminum plate 1 and a disk frame 2. The disk frame 2 includes a disk frame body 20. The aluminum plate 1 is arranged on the disk frame body 20, and the coil 4 of the coil disk is wound around the disk frame 2. For the convenience of display, in Figure 1 it, the coil 4 is located directly below the aluminum plate 1, but in actual application, the structure shown in Figure 1 needs to be inverted up and down.
[0025] As Figure 2 shown, a positioning hole 101 is formed on the aluminum plate 1. The positioning hole 101 can be a round hole. As Figure 3 shown, the disk frame 2 includes a support column 21. The support column 21 is integrally connected with the disk frame body 20. As Figure 4 and Figure 5 shown, a positioning boss 211 is formed at the upper end of the support column 21. A step surface 212 is formed on the outside of the support column 21 at the positioning boss 211. As Figure 7 shown, the positioning boss 211 is adaptively arranged in the positioning hole 101, that is to say, the outer shape of the positioning boss 211 can be set to be circular accordingly; in addition, in some embodiments, the positioning boss 211 can also be rectangular, and correspondingly, the positioning hole 101 can also be set to be a rectangular hole, so that a single positioning boss 211 can prevent the aluminum plate 1 from rotating horizontally; as Figure 7 shown, the step surface 212 abuts against the lower side of the edge part of the positioning hole 101, that is to say, the step surface 212 can support the aluminum plate 1. As Figure 1 and Figure 2 shown, the snap-fastening type coil disk aluminum plate fixing structure of the present utility model further includes a positioning cover 3. As Figure 6 shown, the positioning cover 3 includes a cover plate part 31 and a buckle hook 32. The buckle hook 32 is arranged on the lower side of the cover plate part 31. As Figure 7As shown, the cover plate portion 31 abuts against the upper side of the edge portion of the positioning hole 101, and the buckle 32 is buckled with the support column 21 to prevent the positioning cover 3 from disengaging from the support column 21 upward.
[0026] When assembling the aluminum plate 1 and the disk rack 2, as Figure 2 shown, align the aluminum plate 1 with the disk rack body 20, and align the positioning hole 101 with the corresponding positioning boss 211. Then lower the aluminum plate 1 so that the positioning boss 211 is relatively inserted into the corresponding positioning hole 101. Subsequently, the edge portion of the positioning hole 101 abuts against the step surface 212. Then press down the cover plate portion 31 onto the positioning hole 101 so that the cover plate portion 31 abuts against the upper side of the edge portion of the positioning hole 101, and at the same time, the buckle 32 is buckled with the support column 21, thus quickly completing the assembly of the aluminum plate 1 and the disk rack 2; as Figure 1 and Figure 7 shown, since the positioning boss 211 is adaptively arranged in the positioning hole 101, the displacement of the aluminum plate 1 in the horizontal plane will be blocked by the positioning boss 211. Moreover, since the edge portion of the positioning hole 101 is clamped between the step surface 212 and the cover plate portion 31, the aluminum plate 1 and the disk rack 2 are positioned in the up and down directions, thereby enabling good assembly of the aluminum plate 1 and the disk rack 2; during the above assembly process, after the aluminum plate 1 is covered on the disk rack body 20, due to the positioning effect of the positioning boss 211 on the aluminum plate 1, it is avoided that the aluminum plate 1 is displaced during the subsequent installation of the positioning cover 3, which is beneficial to the stable progress of the assembly. As can be seen from the above, the assembly of the aluminum plate 1 and the disk rack 2 of the present invention avoids the need to use adhesives, avoids the need to wait for a long time for the adhesives to dry, is beneficial to improving the assembly efficiency of the coil disk, and also avoids the odor of the adhesives from polluting the air in the workshop and the trouble of storing the adhesives. Since the present invention sets the combination of the positioning boss 211 and the positioning cover 3 to position the aluminum plate 1, it is avoided that a buckle structure needs to be stamped on the aluminum plate 1, so that the thickness of the aluminum plate 1 can be set smaller, which is beneficial to reducing costs. When the external dimension specifications of the aluminum plate 1 and the disk rack 2 change, only by keeping the dimensions of the support column 21 and the positioning hole 101 unchanged, the same positioning cover 3 can be used, which simplifies the production process.
[0027] Furthermore, as Figure 5 shown, a connection hole 201 is provided in the positioning boss 211. The connection hole 201 is preferably concentric with the positioning boss 211, and an inner convex portion 2011 is formed on the inner wall of the connection hole 201. As Figure 7 shown, the buckle 32 is buckled on the lower side of the inner convex portion 2011. Specifically, as Figure 6As shown, the hook 32 includes a hook portion 321, more specifically, the hook portion 321 is pressed against the lower side of the inner protrusion 2011, so that the positioning cover 3 moves upward and the hook portion 321 is blocked by the inner protrusion 2011. Through the above arrangement, during the assembly process, the positioning cover 3 is moved downward to insert the hook 32 into the connecting hole 201, so that the hook 32 is buckled on the lower side of the inner protrusion 2011. At this time, the edge of the cover plate portion 31 is also pressed against the upper side of the edge of the positioning hole 101. In other words, the assembly of the positioning cover 3 can be completed by a simple straight line downward movement. The above structural arrangement is conducive to simplifying the assembly process. Figure 7 As shown, the upper end of the positioning boss 211 can be arranged flush with the upper surface of the aluminum plate 1, so that the cover plate portion 31 can be a flat plate structure.
[0028] Furthermore, if Figure 5 As shown, the inner protrusion 2011 is arranged in a ring shape. In other words, when viewed from a top view, the inner protrusion 2011 is arranged to cover the entire inner wall of the connecting hole 201. During the assembly of the positioning cover 3, the rotation of the positioning cover 3 does not affect the connection between the hook 32 and the inner protrusion 2011, thus avoiding the need to pay attention to the angle alignment problem, which is conducive to simplifying the assembly process.
[0029] Furthermore, if Figure 6 As shown, the hooks 32 are distributed circumferentially, and the outer ends of the hooks 32 are located on the same circle. Adjacent hooks 32 are separated by separation slits 3200. That is to say, a rotating body structure is formed at the lower part of the positioning cover 3, and the separation slits 3200 divide the above-mentioned rotating body structure into a plurality of hooks 32, so that the outer ends of the hooks 32 (relative to the central axis of the positioning cover 3) are located on the same circle in a top view. Specifically, during the assembly process, the lower ends of the hooks 32 are first inserted into the connecting holes 201, and then the hooks 32 are hindered by the inner convex portion 2011, and downward pressure is applied to the positioning cover 3. The inner convex portion 2011 relatively pushes the hooks 32 inward, so that each hook 32 is elastically bent and deformed inward, so that the hook portion 321 can pass over the inner convex portion 2011 downward, as shown in FIG. Figure 7 As shown, when the hook portion 321 passes over the inner protrusion 2011, the hook portion 321 is moved radially outward and buckled on the lower side of the inner protrusion 2011 through the elastic reset of the buckle hook 32; through the above-mentioned arrangement, when the buckle hook 32 is inserted into the connecting hole 201, the reaction force of the connecting hole 201 on the positioning cover 3 is balanced, which is conducive to the positioning cover 3 being coaxially inserted into the connecting hole 201 in place, which is conducive to the rapid and stable assembly, and after the assembly is completed, the positioning cover 3 is approximately positioned by the inner protrusion 2011 in all horizontal directions, thereby preventing the positioning cover 3 from swinging relative to the rack body 20 and causing the buckle hook 32 to be disengaged.
[0030] Furthermore, if Figure 6As shown, a hook neck portion 320 is formed at the upper end of the buckle 32. Since the buckles 32 are circumferentially distributed, the outer ends of the hook neck portions 320 of each buckle 32 are on the same cylindrical surface, as Figure 7 shown. The hook neck portion 320 is adapted to be adhesively connected to the inner end of the inner convex portion 2011 (the inner end of the inner convex portion 2011 is an inner cylindrical surface), so as to further enhance the radial positioning effect of the support column 21 on the positioning cover 3 and prevent the positioning cover 3 from loosening.
[0031] Further, as Figure 6 shown, the positioning cover 3 includes a positioning ring portion 33, and the positioning ring portion 33 is disposed between the buckle 32 and the cover plate portion 31, as Figure 7 shown. The positioning ring portion 33 is adapted to be connected to the upper end of the connection hole 201, so as to further enhance the radial positioning effect of the support column 21 on the positioning cover 3 and prevent the positioning cover 3 from loosening.
[0032] Further, as Figure 3 shown, a support column 21 is connected to the outer periphery of the disc rack body 20. As Figure 2 shown, a convex ear portion 11 is formed on the outer periphery of the aluminum plate 1, and a positioning hole 101 is correspondingly formed on the convex ear portion 11. Thus, the positioning boss 211 of the support column 21 located on the outer periphery of the disc rack body 20 is adaptively disposed in the positioning hole 101 on the corresponding convex ear portion 11, and the connection hole 201 of the support column 21 located on the outer periphery of the disc rack body 20 is buckled with the corresponding positioning cover 3, so as to reliably position the outer peripheral portion of the aluminum disc 1. The number of the convex ear portions 11 can be set to three. Since the support column 21 for positioning the outer peripheral portion of the aluminum plate 1 is formed on the outer periphery of the disc rack body 20, it is possible to avoid increasing the disc rack body 20 radially, which is beneficial to saving the use of materials.
[0033] Further, as Figure 3 shown, support columns 21 are connected to the radial inner part of the disc rack body 20 in a distributed manner, that is to say, at least two support columns 21 are integrally connected to the part of the disc rack body 20 relatively close to the center of the disc rack body 20. Thus, the radial inner part of the aluminum plate 1 also obtains a positioning effect, and the middle position of the aluminum plate 1 is prevented from bulging.
[0034] Further, as Figure 4 and Figure 5 shown, the step surface 212 is flush with the upper surface of the disc rack body 20, so that the aluminum plate 1 also abuts against the upper surface of the disc rack body 20, which is beneficial to enhancing the positioning effect on the aluminum plate 1. Since the support contact area of the disc rack 2 with the aluminum plate 1 is increased, the aluminum plate 1 is prevented from being easily deformed.
