One side of the internal support member is concave to form a first groove, and first side plates are respectively formed on both sides of the first groove. Each first side plate is provided with a special-shaped hole. One side of the external support member is concave to form a second groove facing the first groove, and second side plates are respectively formed on both sides of the external support member. The second groove accommodates a partial part of the internal support member. Each second side plate is respectively abutted against each first side plate, so that each special-shaped hole is correspondingly superposed on a pre-punched part of each second side plate. Each pre-punched part is pressed into each special-shaped hole and deformed into a corresponding riveting convex part, so that each riveting convex part is fitted into each special-shaped hole.

Description

Technical Field

[0001] The present invention relates to an internal structure body of a bracket for an electronic device and a method for forming the same, specifically to a technology applied in the field of electronic devices, such as a display bracket. It mainly improves the structural design of the internal structure body of the bracket and simplifies the process of the riveting method, so that the internal structure body of the bracket is faster in the manufacturing and forming process and processing and assembly operations. Background Art

[0002] In the bracket of a general display, the internal structure body is the main workpiece supporting the display. The internal structure body usually uses one part as the main structure and is assembled with one or more parts. The manufacturing processes of the foregoing parts adopt stamping parts, casting parts or extrusion parts, and the assembly process is to fix the two parts by screwing between them to form the internal structure body of the bracket. Refer to the patent documents applied by the applicant, such as Component 16 and Component 11 of CN202901749U, which are fixed by screwing between two stamping parts, or for example, Component 151 and 152 of CN107977045B are paired with Component 20 and Component 14, which are fixed by screwing between a stamping part, a casting part and an aluminum extrusion part, or for example, Component 31 of CN208703490U is paired with Component 32 and 36, which are fixed by screwing between a stamping part and an aluminum extrusion part. The foregoing screwing method also needs to adopt technical means such as glue dispensing and anti-slip gaskets (such as washers) to reduce the loosening caused by frequent vibration, but it is also easy to increase the processes and costs. Therefore, in traditional common alternative solutions, except that the welding process is limited by materials, riveting is used to replace the foregoing screwing.

[0003] In the traditional riveting processing operation, riveting the above two parts together relies on an external part - a rivet for joining, and some are to generate the riveting position during the original manufacturing process of the parts. For example, please refer to the previous patent case CN201119196Y applied by the applicant Figures 2 to 4 As shown, before riveting Component 40 and Component 20, Component 20 must first form a fixing hole 23 at a predetermined position, and Component 40 must first be made with a fixing post 41. Then stack Component 20 and Component 40 so that the fixing post 41 passes through and protrudes from the fixing hole 23. Then continue to perform stamping processing on the protruding part of the fixing post 41 of Component 40, so that the protruding part of the fixing post 41 is hammered flat or upset into a head to cover the orifice of the fixing hole 23, that is, the riveting combination is completed; but because the foregoing head is still protruding, when manufacturing the corresponding component, a countersunk part is milled at an orifice of the corresponding component, so that when the foregoing head is formed, it will deform according to the shape of the countersunk part and be filled (or refer to the previous patent case CN205979020U applied by the applicant Figure 8The riveting assembly is thus completed.

[0004] In the above, although the component 40 and the component 20 can be stacked and fixed, observing the structure and connection relationship of the two components, the existing riveting method adopted has multiple process steps in the pre-operation, which is not only complicated, but also only requires making the fixing column 41 and the fixing hole 23 of CN201119196Y (or CN205979020U) in the pre-operation. Figure 8 If there is a slight structural shape and size deviation between the components 341, 343 and 314, 315 shown in the figure, the fixing column 41 and the fixing hole 23 are easily misaligned, and the subsequent riveting process cannot be performed, resulting in the component 40 or the component 20 becoming a waste; it can be seen that only the previous CN201119196Y Figures 2 to 4 In the production and formation of the fixing hole 23 and the fixing column 41 (or the CN205979020U components 341, 343 and 314, 315), the numerous steps will invisibly accumulate and increase the manufacturing tolerance, and prolong the working time of the entire production line, resulting in reduced output, which is easy to reduce the process quality yield, increase scrap and increase costs.

[0028] According to the above description of the main technical features of the present invention, its advantages are: from the structural feature point of view, by respectively using special-shaped holes in the inner and outer support members and matching the rivet protrusions that are deformed by stamping, the structural design of the special-shaped holes is used to share the stress to prevent excessive concentration, and the riveting combination of the rivet protrusions and the special-shaped holes is convenient for rapid docking and fixing, and a small number of parts can be used to form the inner structure of the bracket, which helps to save materials and simplify the process. The two support members can also be made of different materials to match each other so that the inner structure of the bracket forms a composite material structure; on the other hand, in terms of method, by guiding the inner and outer support members to fit together to the position and riveting to form corresponding special-shaped holes and rivet protrusions, it is possible to save the need for additional connectors such as traditional screws and rivets in the prior art, and the tapping and milling of the countersunk head can be omitted after the inner support member is punched out with holes, so that the post-punching processing steps such as tapping and milling the countersunk head can be omitted. In addition to being able to replace screw connections, it can achieve the connection of different materials better than welding, and it can save the structural design and process of pre-forming the convex column (such as the fixed column of the prior art CN201119196Y or the components 341, 343 of CN205979020U) on the outer support member as a sheet metal. The method of the present invention can greatly reduce the time and process of the pre-operation of the existing riveting method, and directly punch the single or multiple pre-punched parts of the outer support member, so that the single or multiple pre-punched parts are squeezed and deformed to be concave toward the corresponding number of special-shaped holes to form a rivet convex part of the corresponding shape. In the processing processes such as manufacturing and assembly, because the pre-operation is omitted, in addition to reducing the accumulation of manufacturing tolerances, it also increases the allowable range of manufacturing tolerances of a single part, and can also speed up the operation time of the production line, which helps to improve the process quality yield as a whole.

Detailed implementation manner

[0052] The following, in conjunction with the accompanying drawings Figures 1 to 20 and specific embodiments, further illustrate the present invention, so that those skilled in the art can better understand the present invention and be able to implement it, but the embodiments cited are not intended to limit the present invention. In terms of structure, please refer to Figure 1 to FIG. 7 and Figures 14 to 20 as shown, which is the internal structure main body of a bracket for an electronic device implemented by the present invention; and in terms of method, please refer to Figures 1 to 13 as shown, which is a method for forming the internal structure main body of a bracket implemented by the present invention; wherein the internal structure main body of the bracket of the present invention further includes an implementation of a support member, please refer to Figures 14 to 19 as shown; the following explains the implementation manner of the present invention.

[0053] The internal structure body of the bracket of the present invention includes an inner support member 10 and an outer support member 20. The inner support member 10 includes two first side plate pieces 11 and a first channel 101 located between the two first side plate pieces 11. The first channel 101 is recessed on one side of the inner support member 10. The two first side plate pieces 11 respectively serve as the opposite side walls of the first channel 101, and each of the first side plate pieces 11 is provided with more than one special-shaped hole 12; and a second channel 201 is recessed on one side of the outer support member 20 and faces the first channel 101, and second side plate pieces 21 are respectively formed on the opposite sides of the outer support member 20. The inner support member 10 is inserted into the second channel 201 of the outer support member 20, so that the second channel 201 of the outer support member 20 accommodates a partial part of the inner support member 10, making the first channel 101 communicate with the second channel 201. Each of the second side plate pieces 21 abuts against each of the first side plate pieces 11, so that each of the special-shaped holes 12 is correspondingly superposed on the pre-punched part 22A of each of the second side plate pieces 21. Each of the pre-punched parts 22A is pressed into each of the special-shaped holes 12 and deformed into a corresponding riveted convex part 22B, so that each of the riveted convex parts 22B is fitted into each of the special-shaped holes 12, thereby riveting and fixing each of the first side plate pieces 11 and each of the second side plate pieces 21 to each other; and the formation method steps of the internal structure body of the bracket by the present invention include: a material preparation process S1, a part process S2, an alignment process S3, and a riveting process S4, gradually making the internal structure body from a prototype into a product; the following will explain in combination with the formation method and structural features.

[0054] In the material preparation process S1, two blanks are prepared. One of the blanks is to be made into the inner support member 10 in subsequent processes. Thus, according to different manufacturing processes, such as stamping / casting / extrusion, etc., metal blanks of different materials are prepared in the material preparation process S1. As for the other blank, it is to be made into the outer support member 20 in subsequent processes, and the two support members are fixed by riveting. Therefore, in terms of selection, a sheet metal blank convenient for stamping manufacturing process is prepared; in this process, the number of the inner support member 10 and the outer support member 20 that can be made per unit length of the blank and the sheet metal blank can, of course, be one or more. Therefore, in subsequent steps, at least one inner support member 10 and at least one outer support member 20 are respectively temporarily used for convenient explanation.

[0055] In the part process S2, it is a forming process step of making the two blanks in the previous process steps into single parts. One of the blanks forms at least one inner support member 10 by manufacturing processes such as stamping / extrusion / casting, etc., so that the at least one inner support member 10 is formed with more than one special-shaped hole 12 (the quantity is not limited, but for the sake of convenient explanation, in Figure 5 、 Figure 7A(Shown in the figure where each of the first side plate pieces 11 is provided with a special-shaped hole 12), and at least one outer support member 20 is formed from another blank of the plate material by a stamping manufacturing process. Also, for the convenience of the subsequent alignment process S3, it is better that both of these support members adopt the same manufacturing process, such as stamping. In addition to the structural design of the local parts of the above side plate pieces, the overall structure of a single part can also be designed into different shapes. For example, the at least one inner support member 10 and the at least one outer support member 20 are respectively designed into a bent shape, so that both of these support members have a longitudinal length and are adjacent side plate pieces for supporting purposes, which will cause a first channel 101 to be concave on one side of the at least one inner support member 10, and a second channel 201 to be concave on one side of the at least one outer support member 20. Among them, the angle between the two side plate pieces of the at least one inner support member 10 (a connecting side plate piece and a first side plate piece 11) is less than 90 degrees (for example, stamped and bent into 89 degrees), and the angle between the two side plate pieces of the at least one outer support member 20 (a connecting side plate piece and a second side plate piece 21) is greater than 90 degrees (for example, stamped and bent into 91 degrees), so that the cross-sections of these two support members can be selectively formed into an L shape, a V shape, a C shape, a U shape, a C shape, or any combination of any two of them. Among them, the L shape is relatively simple, and the C shape is more convenient for these two support members to be butt-jointed with each other and the local parts to be abutted and overlapped in the subsequent alignment process S3; and a plurality of special-shaped holes 12 are further longitudinally arranged on one side or opposite sides of the first side plate pieces 11 of the at least one inner support member 10.

[0056] In the alignment process S3, the local part of the at least one inner support member 10 is brought close to the local part of the at least one outer support member 20. Since these two support members have been stamped and bent into a slightly different C shape, it is easy for the local part of the at least one inner support member 10 to be introduced into the second channel 201 of the at least one outer support member 20. During the introduction process, the local parts between the opposite side plate pieces of these two support members will be abutted and overlapped with each other, reducing the generation of gaps, and guiding to gradually increase the interference between them until they are positioned at a predetermined position. Finally, the second channel 201 accommodates the local part of the inner support member 10 to form the prototype of the inner structure body of the bracket. Among them, the local parts of the at least one outer support member 20 respectively become pre-punched parts 22A corresponding to the positions of the special-shaped holes 12, and the pre-punched parts 22A are aligned with the special-shaped holes 12.

[0057] In the riveting process S4, which is the forming process step of riveting and fixing the prototype of the inner structure body of the previous process step into a finished product, each of the special-shaped holes 12 of the at least one inner support member 10 is abutted against a working surface WS (see Figure 8), Subsequently, the pre-punched portions 22A are stamped from the outside of the at least one outer support member 20, so that the pre-punched portions 22A are deformed by the force and recessed toward one end of the corresponding irregular holes 12 respectively, thereby forming the riveting convex portions 22B. And the outer shape of each of the riveting convex portions 22B follows the shape of each of the irregular holes 12. Also, the end faces of the riveting convex portions 22B are blocked by the working surface WS and will not protrude from the orifice at the other end of each of the irregular holes 12, so that the two support members are riveted and fixed into the inner structure main body product of the bracket.

[0058] According to the main technical definition of the present invention described above, from the perspective of production, the production line process does not need to perform complex pre-processing operations on the outer support member 20 and the inner support member 10. Only during the part forming process, it is necessary to perform punching on the inner support member 10. Compared with the prior art that requires pre-prepared rivets or forming convex columns in the component of the previous case CN201119196Y, the punching process is simpler. And it is not necessary to punch and mill the counterbore part like the corresponding component in the previous case CN205979020U. In the present invention, only the inner support member 10 with the irregular holes 12 punched is inserted into the second channel 201 of the outer support member 20. After completing the docking combination of the inner support member 10 and the outer support member 20, the pre-punched portions 22A of the outer support member 20 can be stamped, or through a jig (such as Figures 8 to 13 shown) for accurate stamping, so that the pre-punched portions 22A are deformed and recessed toward the orifice at one end of each of the irregular holes 12. After the pre-punched portions 22A are subjected to the processing stamping external force, they will axially and laterally deform into protruding riveting convex portions 22B. Each of the riveting convex portions 22B will closely fit and press against the inner hole wall of each of the irregular holes 12, thereby achieving the effect of riveting and fitting. And the overall structural strength of the two support members after being tightly assembled can resist the influence of external forces (shearing force and tensile force) between them. And by using the riveting method of the present invention, many task sequences and pre-processing operations can be omitted, and the production cost and assembly time can be reduced. Please see Figures 1 to 13 shown.

[0059] For further description of other technical features of the present invention, please see the second to Figure 7A , Figure 7B and Figure 7C shown. In order to strengthen the firm riveting between each of the riveting convex portions 22B and the corresponding irregular holes 12, in the part process S2, each of the irregular holes 12 of the formed first side plate pieces 11 includes a circular through hole 121 and further recesses one or more side holes 122 at its hole edge respectively. The side holes 122 are circular hole types and penetrate through the inner support member 10 and are communicated with the through hole 121. Also, the hole diameter of the side holes 122 is smaller than the hole diameter of the through hole 121. The side holes 122 can be single side holes (such as the Figure 7B) In addition to the settings, two side holes 122 (such as Figure 7A ) or more than three side holes 122 (such as Figure 7A ) are provided around the perforation 121, and there is a spacing between each of the side holes 122. In this way, when each of the pre-punched parts 22A in the riveting process S4 deforms, the stress influence can be shared. That is, after the inner support member 10 and the outer support member 20 are mutually butted and combined, the manufacturer can use the punch of the existing processing equipment (such as a punching machine, a hand press) to punch one or more pre-punched parts 22A from the outer periphery of the outer support member 20. Please refer to Figure 5 、 Figure 7A as shown. Each of the pre-punched parts 22A is subjected to a punching external force and deforms. At present, it will first be pressed concave and squeezed into the perforation 121 of each of the shaped holes 12. When each of the pre-punched parts 22A encounters each of the side holes 122 communicating with the periphery of the perforation 121 during the process of deforming and recessing, each of the continuously deforming pre-punched parts 22A will be further squeezed into each of the side holes 122, or each of the pre-punched parts 22A will be continuously squeezed and deformed to touch a working surface (such as the surface of a jig) and be stopped, so that each of the finally formed rivet convex parts 22B further respectively includes a main convex area 221 and one or more side convex areas 222 connected thereto. The main convex area 221 corresponds to the perforation 121, and the side convex area 222 corresponds to the side hole 122. The number of the side convex areas 222 can also be set singly (such as Figure 7C ) In addition to this, two side convex areas 222 (such as Figure 7B ) or more than three side convex areas 222 (such as Figure 7A ) are provided around the main convex area 221. By providing each of the side holes 122, it helps to share the influence of the deformation stress and accommodate the overflow parts of each of the pre-punched parts 22A deformed and extruded from each of the perforations 121, so that the contour shapes of each of the rivet convex parts 22B formed after the stamping process correspond to the shapes of each of the shaped holes 12, but will not protrude from the hole openings at the other ends of each of the shaped holes 12, so as to form a certain tensile and shear strength between the inner support member 10 and the outer support member 20, and there will be no problem of shaking between them and they can be firmly riveted.

[0060] Continuing the above, in the setting between each of the perforations 121 and the mutually cooperating side holes 122, the hole diameter of the perforation 121 of each of the first side plates 11 is larger than the hole diameter of each of the side holes 122. And when the number of each of the side holes 122 is more than three, and the distances connected between the hole centers of each of the side holes 122 are equal, and the area surrounded by connecting the hole centers of each of the side holes 122 defines a side center point E (see Figure 7A) The center of the hole of each of the perforations 121 coincides with the center point E on that side. In this way, after each of the pre-punched parts 22A is processed by the punch of the processing equipment, it helps to distribute the deformed parts and stress to more than three side holes 122. The subsequent deformation will form a riveting convex part 22B according to the shape of the perforation 121 and each of the side holes 122. By increasing the area of the contact part between each of the side convex areas 222 and each of the side holes 122, the connection between them becomes tighter and has tensile and shear strength, thereby effectively preventing the problem of shaking. Please refer to Figure 7A shown; as for the opposite wall surfaces of each of the riveting convex parts 22B, they are concave corresponding to the punch (see Figure 6 ).

[0061] In addition, it is worth mentioning that there is a technical means to guide and position the two support members to a predetermined position in alignment with each other. Please refer to Figure 1 、 Figure 3As shown, on each of the second side plates 21 of the outer support member 20 and adjacent to the notch edge of the second channel 201, one or more guiding notches 23 are further recessed. The caliber of the guiding notch 23 is tapered and in a V shape. Correspondingly, one or more positioning studs 13 are respectively protruded on the outer surface of the first side plate 11 of the inner support member 10. For example, the positioning studs 13 formed on the surface of the at least one inner support member 10 and the guiding notches 23 formed by stamping the edge of the at least one outer support member 20 can also be implemented in one or more ways. Thus, the position where the positioning stud 13 is inserted and positioned in the guiding notch 23 is used as a predetermined position in the alignment process S3. The guiding notch 23 formed in the part process S2 further includes a guiding section 231 and a positioning section 232. The guiding section 231 is adjacent to the notch of the second channel 201 and forms a gradually converging shape towards the inside of the channel. The positioning section 232 is adjacent to the converging end of the guiding section 231 and extends from the converging end towards the inside of the channel, and the reverse extension end point is used as the predetermined position in the alignment process S3. Subsequently, in the alignment process S3, when the inner support member 10 is inserted into the second channel 201 of the outer support member 20, the positioning studs 13 of each of the first side plates 11 are aligned with the corresponding guiding notches 23. The positioning studs 13 of each of the first side plates 11 enter from the open end of each guiding notch 23, are guided through each guiding section 231, and after the inner support member 10 is inserted into the second channel 201, each positioning stud 13 is clamped at the end point inside the positioning section 232 of each guiding notch 23. Accordingly, the two support members are in a combined positioning state. After applying force to the two support members respectively and checking and confirming the positioning with each other, the riveting process S4 is entered. With the cooperation of each positioning stud 13 and each guiding notch 23, the present invention enables the assembler to quickly combine and position the inner support member 10 and the outer support member 20 without being easily separated. Moreover, in addition to the riveting and fixing between each shaped hole 12 and each riveting convex part 22B, the cooperation of each positioning stud 13 and each guiding notch 23 can strengthen the firmness between the inner support member 10 and the outer support member 20, increase the structural strength, and eliminate the possibility of up and down shaking.

[0062] Also, in the above-mentioned riveting process S4, a stamping die is further used, which is installed in processing equipment such as an existing stamping machine. Please refer to Figures 9 to 13 As shown, the stamping die includes an upper die block 60, a lower die block 70A, 70B, and an auxiliary die block 50. The auxiliary die block 50 is arranged between the upper die block 60 and the lower die blocks 70A, 70B and has a hollow groove 51 (see Figure 13 ), for a core part 532 included in the auxiliary die block 50 to be horizontally suspended in the hollow groove 51. The working surface WS is located on the circumferential surface of the core part 532. Also, a hollow groove notch 52 is provided on one side of the auxiliary die block 50 (see Figure 13), the hollow groove notch 52 communicates with the hollow groove 51 to allow a partial portion of the horizontally arranged core portion 532 to protrude; wherein the upper module 60 includes an upper die base 61, an upper movable member 62, and more than one upper punch 63. A first limiting groove 65 is recessed in the bottom of the upper die base 61 parallel to the horizontally arranged core portion 532. A partial portion of the upper movable member 62 elastically moves in the first limiting groove 65. The upper punch 63 extends from the first limiting groove 65 and can pass through the upper movable member 62 to correspond to one side surface of the horizontally arranged core portion 532. More than one upper elastic member 64 is provided between the upper die base 61 and the upper movable member 62 to allow the upper movable member 62 to reciprocate and assist the upper punch 63 in stripping. Wherein the lower modules 70A, 70B further include a lower die base 71, lower die members 72A, 72B, and more than one lower punch 73. A second limiting groove 75 is recessed in the top of the lower die base 71 parallel to the horizontally arranged core portion 532. Partial portions of the lower die members 72A, 72B are located in the second limiting groove 75. The lower die members 72A, 72B can be divided into fixed type and movable type. The fixed lower die member 72A can be used as a gasket as shown in Figure 9 , and the movable lower die member 72B is used as a stripping member in cooperation with the lower punch 73 as shown in Figures 10 to 13 . The lower punch 73 extends from the second limiting groove 75 and can pass through the lower die member 72B to correspond to the other side surface of the core portion 532. More than one lower elastic member 74 is provided between the lower die base 71 and the lower die member 72B to allow the lower die member 72B to reciprocate and assist the lower punch 73 in stripping. Thereby, in the riveting process S4, the lower punch 73 and the upper punch 63 can respectively punch the pre-punched portions 22A on both sides of the inner structure main body prototype of the bracket, which is time-saving and convenient for subsequent assembly.

[0063] The above-mentioned auxiliary module 50 further includes two auxiliary members 53A, 53B, two limiting members 54, 55 and a side movable member 56. The auxiliary members 53A, 53B further include a stop portion 531 and a core portion 532. The two limiting members 54, 55 and the stop portion 531 of the auxiliary members 53A, 53B jointly define the hollow groove 51 and the hollow groove notch 52. The horizontally arranged core portion 532 is located in the hollow groove 51 and partially protrudes from the hollow groove notch 52. The core portion 532 is a straight rod and is horizontally arranged on one side of the stop portion 531. The stop portion 531 stands on the lower die base 71 and is near one end of the second limiting groove 75. One end (free end) of the horizontally arranged core portion 532 has an inclined surface 5322, and the inclined surface 5322 corresponds to the top structure shape of the inner structure body prototype of the bracket. Together with the bent inner and outer support members, it forms an anti-misassembly function, enabling the inner structure body prototype of the bracket to be introduced from the hollow groove notch 52 and firmly sleeved on the core portion 532, and then abutted against the side of the stop portion 531. On the other hand, as Figure 13 shown, the side movable member 56 is located on the other side of the stop portion 531 and corresponds to the horizontally arranged core portion 532. The side movable member 56 is combined with one or more horizontal straight rods. The two limiting members 54, 55 are symmetrically arranged on both sides of the horizontally arranged core portion 532. The stop portion 531 also penetrates through one or more horizontal through holes 5311. One or more straight guide grooves 5321 are also provided on the peripheral side of the core portion 532. The straight guide grooves 5321 divide the peripheral surface of the core portion 532 into at least two working surfaces WS. After riveting and fixing, as Figure 12 、 Figure 13 shown, the side movable member 56 is driven by a power source (such as human force or air pressure) and the horizontal straight rods sequentially pass through the horizontal through holes 5311 and the straight guide grooves 5321, thereby pushing the inner structure body product of the bracket to separate from the core portion 532.

[0064] The above-mentioned auxiliary members 53A, 53B are jigs for guiding the inner structure of the support to be sleeved in place or facilitating the separation of the core portion 532. The auxiliary members 53A, 53B can be divided into fixed type and movable type. The difference lies in whether the core portion 532 can move in cooperation with the stamping action, resulting in differences in the matching lower modules 70A, 70B. The following is a detailed description.

[0065] When using the fixed auxiliary member 53A, it can be applied to an existing manual press table, as Figure 8As shown, the stop portion 531 can be locked and stand on the lower die base 71, so that the horizontally arranged core portion 532 is fixed to one side of the stop portion 531 and is in a suspended state. The lower die member 72A is a manually adjustable cushion member, and its bottom is fitted in the second limit groove 75 of the lower die base 71. A number of locking holes are arranged at intervals on the lower die base 71 for manually adjusting the locking position of the stop portion 531. Therefore, when the punch (which can be regarded as the upper punch 63) of the existing hand press is manually operated to press down, only a pre-punching portion 22A on one side of the inner structure main body prototype of the bracket is punched. Then, the stop portion 531 is displaced continuously for the punch to punch the next pre-punching portion 22A. After all the riveting and fixing are completed, the inner structure main body product of the bracket is manually pulled out from the core portion 532. Also, the implementation method of the fixed auxiliary member 53A and the fixed lower die member 72A can also be applied to the existing punching machine, such as Figure 9 shown by the lower die block 70A of

[0066] When the movable auxiliary member 53B is adopted, the opposite side surfaces of the horizontally arranged core portion 532 are respectively used as the working surfaces WS, and the lower die base 71 is used in combination with the movable lower die member 72B. This implementation method can be applied to the existing punching machine. For the punching die, please refer to Figures 10 to 13 As shown, although the horizontally arranged core portion 532 is connected to one side of the stop portion 531, since a longitudinal guide groove is provided on this side of the stop portion 531, the longitudinal guide groove can be communicated with the second limit groove 75, and one end of the core portion 532 can move up and down along the longitudinal guide groove. Thus, when the core portion 532 is pressed down and displaced by the upper die block 60, the upper die block 60 indirectly presses down the movable lower die member 72B to displace until the upper punch 63 and the lower punch 73 respectively punch each of the pre-punching portions 22A on both sides of the inner structure main body prototype of the bracket. After each of the pre-punching portions 22A is deformed and recessed into each of the shaped holes 12 to form each of the riveting convex portions 23B (as shown in Figure 11 ), the upper die block 60 rises, and the lower elastic member 74 of the lower die base 71 releases elastic force to jack up the movable lower die member 72B, indirectly lifting the horizontally arranged core portion 532 to return to its original position. At this time, one end of the straight guide groove 5321 corresponds to one end hole of the transverse through hole 5311 (which can be seen in Figure 10 ). One end of the side movable member 56 is pushed by air pressure, and the transverse straight rod at the other end of the side movable member 56 passes through the transverse through hole 5311 and then enters the straight guide groove 5321 to push the inner structure main body product of the bracket away from the core portion 532 (as shown in Figure 13 ).

[0067] Secondly, the present invention also adds ingenious technical features to the structural design of the inner and outer support members in the above-mentioned part process S2. Please refer to Figure 3 、 Figure 4 、 Figure 14As shown, a first long opening 15 is further provided in the inner support member 10. The first long opening 15 corresponds to the notch of the first channel 101, and a plurality of side protrusions 151 are longitudinally arranged on the opposite two side edges of the first long opening 15. Each of the side protrusions 151 in each row is grouped in pairs of two corresponding side protrusions, and the distance between the two side protrusions 151 in each group is the same; also see Figure 3 As shown, a second long opening 25 is further provided in the outer support member 20. The second long opening 25 corresponds to the notch of the second channel 201, and a plurality of side protrusions 251 are further longitudinally arranged on the opposite two side edges of the second long opening 25. Each of the side protrusions 251 in each row is grouped in pairs of two corresponding side protrusions, and the distance between the two side protrusions 251 in each group is the same; therefore, in the present invention, the setting direction of each group of two side protrusions extends horizontally towards the center of their respective long openings. The main function of each group of two side protrusions is to provide the manufacturer with a means for detecting and identifying the size of their respective long openings. In this way, the side protrusions on both sides of each long opening will be at the same horizontal height under standard dimensions. Therefore, if the two corresponding side protrusions in each group are not at the same horizontal height, or if there are differences in the distances between groups, it means that the opening of the long opening is skewed, non - positive, etc., and there is no need to measure the distances between each point on the opposite two longitudinal sides of each long opening one by one. Therefore, after the two support members are formed in the above - mentioned part process S2, by measuring the settings of each group of two side protrusions, it helps to provide the manufacturer with a quick way to check the accuracy of the setting of their respective long openings on their respective support members (quickly detect whether the part size is within the tolerance range).

[0068] Furthermore, in order to connect an electronic device such as a display (not shown in the figure), please refer to Figure 2 、 Figures 14 to 19As shown, the internal structure main body of the bracket of the present invention further includes a support member 40. At least one notch 17 is provided at the top of the internal structure main body of the bracket for inserting one end of the support member 40. The other end of the support member 40 is connected to a receiving plate 42, and then the display (not shown in the figure) is connected via the receiving plate 42. The support member 40 is formed by the forming method of the present invention. In the above-mentioned material preparation process S1, an additional blank needs to be prepared, preferably a sheet metal blank. In the above-mentioned part process S2, at least one support member 40 is preferably formed by a stamping manufacturing process. After the above-mentioned riveting process S4 completes the internal structure main body product of the bracket, one end of the support member 40 is inserted into at least one notch 17 at the top of the internal structure main body. In order to enable the internal structure main body of the bracket to quickly insert or disassemble the support member 40, in the overall structural design, the bottom surface of the support member 40 is recessed to form a third channel 401, and a third side plate 41 is formed on each of the opposite sides of the third channel 401. Each of the third side plates 41 is provided with more than one convex column 43. In the setting of the inner support member 10, in addition to the two first side plates 11 and the first channel 101, the top of the inner support member 10 further includes two hooks 14 and an abutting portion 16. The abutting portion 16 is a connecting piece and protrudes with at least one limiting convex block 18. The abutting portion 16 is mainly connected to the hooks 14 at the tops of the two first side plates 11 at the corresponding two side edges (as Figure 15 shown), so that the abutting portion 16 and the at least one notch 17 are located between the hooks 14. A guiding groove 141 is formed at the edge of each of the hooks 14. The mouth of each guiding groove 141 is communicated with the at least one notch 17. Each of the guiding grooves 141 has an inclined guiding section 142 for the convex columns 43 to be respectively guided into the guiding grooves 141 along the inclined guiding sections 142 to be positioned, so that each of the hooks 14 is respectively clamped to each of the convex columns 43, and the abutting portion 16 is inserted into the third channel 401 to abut against the support member 40. On the other hand, an extension portion 44 is formed at the end of the support member 40 along the third channel 401. A plurality of stop pieces 24 are further extended at the top end of the outer support member 20. Each of the stop pieces 24 is suspended at one end of the second channel 201 and jointly defines the top structure shape of the internal structure main body of the bracket for the extension portion 44 to pass through the at least one notch 17 and be inserted into the second channel 201 to abut against. If in order to further tightly fix each other, a plurality of screws 33 can be used to lock the stop pieces 24 and the lock holes of the extension portion 44 of the support member 40.

[0069] In addition, in order to prevent the entire internal structure main body of the bracket from being exposed, please see Figures 17 to 19As shown, it is also necessary to sleevedly install the inner structure main body product of the bracket in the above riveting process S4 into a housing 30. Therefore, after the inner structure main body product of the bracket is completed in the above riveting process S4, the invention will slide into the interior from the bottom end of the housing 30 until at least one limiting convex block 18 catches the inner wall surface of the housing 30, and the assembly can be completed. In addition to preventing the inner structure main body product of the entire bracket from shaking within the housing 30, the setting of the at least one limiting convex block 18 in cooperation with the bent outer support member also achieves the effect of preventing misoperation; further, a through hole 31 is provided on the circumferential surface of the housing 30, and the orifice of the through hole 31 corresponds to the first long opening 15 and / or the second long opening 25. The size of the through hole 31 is slightly smaller than that of the first long opening 15 and / or the second long opening 25, so that the opposite side shell walls of the orifice of the through hole 31 respectively cover each row of the side convex blocks 151, 251 to allow wires and other wire materials to pass through. Moreover, each of the side convex blocks 151, 251 in cooperation with the at least one limiting convex block 18 also helps the housing 30 and the inner structure main body product of the bracket to be stably clamped; further, an opening 32 is provided at the top of the housing 30 to correspond to at least one notch 17 provided at the top of the inner structure main body for the support member 40 to be inserted, and the above screw 33 can be locked to the tops of the two support members from the top of the housing 30; in addition, when an assembler such as an operator assembles the inner structure prototype of the above riveting process S4 to sleeve the central core part 532, or the combination of the housing 30 and the entire group of brackets, the installation direction can be identified through the setting of the at least one notch 17 or at least one convex block 18 to prevent incorrect installation and inability to pull out the housing 30.
