Description

Technical Field

[0001] This invention relates to plastic sheets, and more particularly to thermoforming sheets. Background Technology

[0002] Vacuum-formed sheet is an amorphous, odorless, non-toxic, highly transparent colorless or slightly yellow thermoplastic engineering plastic with excellent physical and mechanical properties, low creep, and dimensional stability. It also exhibits good heat and low-temperature resistance, maintaining stable mechanical properties, dimensional stability, electrical properties, and flame retardancy over a wide temperature range, allowing for long-term use at temperatures from -60°C to 120°C. It has no distinct melting point, remaining molten at 220-230°C. Due to its high molecular chain rigidity, the resin melt has high viscosity, resulting in low water absorption, low shrinkage, high dimensional accuracy, good dimensional stability, and low film permeability. Based on these characteristics, furniture made from vacuum-formed sheets is widely used in daily life.

[0003] However, traditional vacuum forming panels cannot be molded into a structure that can be fixedly connected to a metal frame during vacuum forming. Therefore, how to connect the vacuum forming panel to the metal support has always been a rather troublesome problem. Summary of the Invention

[0047] To make the technical solution and features of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific examples. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art fall within the scope defined by the appended claims.

[0048] Example 1

[0049] refer to Figures 1-24 This embodiment provides a storage device, specifically a storage box. The storage box includes a metal support frame and a panel. To securely connect the vacuum-formed panel and the support frame, this embodiment employs a vacuum-formed composite panel. The vacuum-formed part 1 and the injection-molded part 3 are riveted together to form an assembly, which is then fixedly connected to the support part 2 via a connecting structure on this assembly. This solves the problem that the vacuum-formed part 1 is not easily molded into a connecting structure for fixed connection with the support part 2 during vacuum forming. Various connecting structures can be formed on the injection-molded part 3 during the injection molding process, thereby securing it to the support part 2.

[0050] Specifically, in this embodiment, the blister component 1 is a blister panel, and the support component 2 is a support frame. Since the blister panels on each side of the storage box are not identical, the assemblies formed by the blister component 1 and the injection-molded component 3 are also different, and the connection and fixing methods between the assemblies and the support frame are also different. Therefore, this embodiment selects three positions of the storage box for detailed description: the top panel, the front panel, and the side panels, corresponding to... Figure 1 The three positions A, B, and C in the diagram.

[0051] For the top panel at position A, the top panel is a double-layer vacuum-formed panel. During vacuum forming, the outer layer of the double-layer vacuum-formed panel extends downward along the thickness direction of the top panel to form an insertion part 11 that intersects with the injection-molded part 3. The injection-molded part 3 has an upward-opening U-shaped slot 31, so that the insertion part 11 can be inserted into the U-shaped slot 31 and then riveted and fixed together, thereby achieving the purpose of riveting the vacuum-formed part 1 and the injection-molded part 3 to form an assembly. At the same time, in order to fix the assembly to the support frame, the injection-molded part 3 is formed with a post 32 for insertion into the support member 2 during the injection molding process as the connection structure. The end of the post 32 is provided with a connection hole 33. The support frame pre-punches a clearance hole 21 at the position corresponding to the post 32. After the post 32 is inserted into the support member 2, it can be connected and fixed by bolts 22 passing through the clearance hole 21 and the connection hole 33.

[0052] For the side panel at position B, the side panel is a single-layer vacuum-formed panel. During vacuum forming, the side panel is formed with an insertion part 11 that interlocks with the injection molded part 3 along a direction perpendicular to the side panel. The injection molded part 3 has an upward-opening U-shaped slot 31, so that the insertion part 11 can be inserted into the U-shaped slot 31 and then riveted and fixed together with the U-shaped slot 31, thereby achieving the purpose of riveting the vacuum-formed part 1 and the injection molded part 3 to form an assembly.

[0053] For the front panel at position C, the front panel is a single-layer vacuum-formed panel. During vacuum forming, the side panel is formed with an insertion part 11 that intersects with the injection molded part 3 along the direction perpendicular to the side panel. The injection molded part 3 has an upward-opening U-shaped slot 31, so that the insertion part 11 can be inserted into the U-shaped slot 31 and then riveted and fixed together, thereby achieving the purpose of riveting the vacuum-formed part 1 and the injection molded part 3 to form an assembly. At the same time, in order to fix the assembly to the support frame, the injection molded part 3 is formed with a post 32 for insertion into the support member 2 during the injection molding process. The end of the post 32 is provided with a connecting hole 33. The support frame pre-punches a clearance hole 21 at the position corresponding to the post 32. After the post 32 is inserted into the support member 2, it can be connected and fixed by bolts 22 passing through the clearance hole 21 and the connecting hole 33.

[0054] As a simple alternative to the above connection method, the assembly and support 2 can also be connected by riveting or snap-fitting.

[0055] Example 2

[0056] refer to Figure 25 In Example 1, the injection molded part 3 has a U-shaped slot for the blister pack 1 to be inserted and then riveted together. However, in this example, the injection molded part 3 is single-layered and is simply attached to the outer side of the blister pack 1 and then riveted together with the blister pack 1.

[0057] Example 3

[0058] refer to Figure 26 The difference between this embodiment and embodiment 2 is that the injection molded part 3 is attached to the inner side of the blister part 1 and then riveted to the blister plate.

[0059] Example 4

[0060] refer to Figure 27 Based on Embodiment 2, this embodiment utilizes the feature that the insertion part 11 and the U-shaped slot 31 protrude and expand after riveting to form an enlarged part 34, and uses the enlarged part 34 as the connecting structure. A socket 23 can be punched in the support member 2, and the enlarged part 34 can be inserted into the socket 23 to form an interference fit, thus fixing the assembly to the support member 2.

[0061] Example 5

[0062] refer to Figure 28 The difference between this embodiment and embodiment 3 is that the blister part 1 is a double-layer blister board, and the inner and outer layers of the double-layer blister board are riveted to the injection molded part 3 respectively.

[0063] Example 6

[0064] refer to Figure 29 The difference between this embodiment and Embodiment 1 is that in Embodiment 1, at point A, only the outer layer of the double-layer thermoforming plate is riveted to the injection molded part 3. In this embodiment, the double-layer thermoforming plate is inserted into the U-shaped slots 31 of the injection molded part 3 and then riveted to the injection molded part 3.

[0065] Example 7

[0066] refer to Figure 30 The difference between this embodiment and embodiment 6 is that in this embodiment, the injection molded part 3 is divided into two parts, which are respectively disposed on the inner and outer sides of the blister molded part 1 and riveted to the blister molded part 1. This replaces the U-shaped slot in embodiment 6.

[0067] Example 8

[0068] refer to Figures 31-56 This embodiment provides a support device, specifically a chair. The chair includes a metal support frame, a support plate, and a backrest. To ensure a fixed connection between the support plate, backrest, and support frame, this embodiment employs a vacuum-formed composite panel. The vacuum-formed part 1 and the injection-molded part 3 are riveted together to form an assembly, which is then fixedly connected to the support part 2. This solves the problem that the vacuum-formed part 1 is not easily molded into a connection structure for fixed connection with the support part 2 during vacuum forming. Various connection structures can be formed on the injection-molded part 3 during the injection molding process, thereby achieving a fixed connection with the support part 2.

[0069] Specifically, in this embodiment, the vacuum-formed component 1 is the support plate and the backrest, and the support component 2 is the support frame. Since the support plate and the backrest are not the same as the support frame, the assemblies formed by the vacuum-formed component 1 and the injection-molded component 3 are also different, and the connection and fixing methods between the assemblies and the support frame are also different. Therefore, this embodiment selects four positions of the chair for detailed description: the upper part, side, and middle of the backrest, and the front part of the support plate, corresponding to... Figure 31 The four positions are D, E, and F.

[0070] For the back panel at position D, during vacuum forming, the upper end of the back panel is bent at a certain angle to form an insertion part 11 that inserts into the injection molded part 3. The injection molded part 3 has an upward-opening U-shaped slot 31, so that the insertion part 11 can be inserted into the U-shaped slot 31 and then riveted and fixed together with the U-shaped slot 31, thereby achieving the purpose of riveting the vacuum-formed part 1 and the injection molded part 3 to form an assembly.

[0071] For the backrest panel at position E, during vacuum forming, the upper end of the backrest panel is bent at a certain angle to form an insertion part 11 that inserts into the injection molded part 3. The injection molded part 3 has an upward-opening U-shaped slot 31, so that the insertion part 11 can be inserted into the U-shaped slot 31 and then riveted and fixed together, thereby achieving the purpose of riveting the vacuum-formed part 1 and the injection molded part 3 to form an assembly. At the same time, in order to fix the assembly to the support frame, the injection molded part 3 is formed with a clamping cavity 34 for clamping with the support frame as a connection structure during the injection molding process. In this embodiment, the support frame at this location is a circular tube, so the cross-section of the clamping cavity 34 is also circular.

[0072] For the backrest panel at position F, during vacuum forming, the upper end of the backrest panel is bent at a certain angle to form an insertion part 11 that inserts into the injection molded part 3. The injection molded part 3 has an upward-opening U-shaped slot 31, so that the insertion part 11 can be inserted into the U-shaped slot 31 and then riveted and fixed together with the U-shaped slot 31, thereby achieving the purpose of riveting the vacuum-formed part 1 and the injection molded part 3 to form an assembly.

[0073] For the support plate at position G, during vacuum forming, the front end of the support plate is bent at a certain angle to form an insertion part 11 that inserts into the injection molded part 3. The injection molded part 3 has an upward-opening U-shaped slot 31, so that the insertion part 11 can be inserted into the U-shaped slot 31 and then riveted together to fix the insertion part 11 and the U-shaped slot 31, thereby achieving the purpose of riveting the vacuum-formed part 1 and the injection molded part 3 to form an assembly. In addition, taking advantage of the feature that the insertion part 11 and the U-shaped slot 31 protrude and expand after riveting to form an enlarged part 34, the enlarged part 34 is used as a connecting structure. A hole 23 can be punched in the support member 2, and the enlarged part 34 is inserted into the hole 23 to form an interference fit with the hole 23, thereby fixing the assembly to the support member 2.

[0074] Regarding the riveting method for the blister part 1 and the injection part 3, this embodiment can also be replaced by the riveting method described in embodiments 2-7, which will not be repeated here.

[0075] The above is only one specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be deemed as infringing the protection scope of the present invention.
