[0002] Currently, most traditional greeting cards are flat, presenting patterns and text through printing and painting, which limits their visual appeal and interactivity. To enhance the aesthetics and fun of greeting cards, 3D greeting cards have emerged. Early 3D greeting cards often used simple folding structures, utilizing the elasticity and folding design of paper to present a simple 3D shape when unfolded. However, these cards had relatively simple structures, lacked rich and realistic 3D effects, and had relatively rough manufacturing processes, making it difficult to present complex patterns and multi-layered structures. With technological advancements, subsequent 3D greeting cards using laser cutting and die-cutting processes emerged, enabling more refined structures and more complex 3D shapes. However, the production cost was high, and the difficulty and barriers to entry for small manufacturers or individual users were significant. Furthermore, the 3D structure of these cards was easily damaged during transportation and storage, limiting their widespread application.

[0029] The unfolding structure includes a telescopic rod 102 and a first spring 103. The first spring 103 is disposed inside the telescopic rod 102. After the telescopic rod 102 retracts, it is used to compress the first spring 103. The two ends of the telescopic rod 102 are respectively hinged to the upper and lower ends of the folding plate 101. The end faces of the upper and lower ends of the folding plate 101 are also provided with clearance grooves 104, which are used to make way for the telescopic rod 102.

[0030] This utility model mainly includes a folding plate 101, an unfolding structure, and a locking structure. In actual use, when unfolding the folding plate 101, the user first unlocks the locking structure, allowing the folding plates 101 to unlock. During the unfolding process, the first spring 103 inside the telescopic rod 102 is no longer compressed, and the telescopic rod 102 is extended by the elastic force of the first spring 103 until the folding plate 101 is fully unfolded. The content of the greeting card is fixed on the first plate 105 and the second plate 106 for full display. When it is necessary to store the greeting card, the user folds the folding plate 101 with both hands, so that the two ends of the folding plate 101 interlock. Finally, the locking structure fixes the two ends of the folding plate 101, thus completing the overall carrying and storage of the metal greeting card. The advantage of this design is that it makes it easy for users to store or unfold the metal greeting card, making storage convenient, unfolding fast, and operation simple.

[0031] In some embodiments, the folding plate 101 includes a first plate 105 and a second plate 106, which are hinged to each other. The locking structure is used to keep the first plate 105 and the second plate 106 in a fastened state. The two ends of the telescopic rod 102 are respectively hinged to the first plate 105 and the second plate 106. The clearance groove 104 is provided on the first plate 105 and the second plate 106.

[0032] In actual use, when the first plate 105 and the second plate 106 are fastened together, the lower end of the first plate 105 contacts the upper end surface of the second plate 106. When the first plate 105 and the second plate 106 are unfolded, the side of the first plate 105 contacts the side of the second plate 106.

[0033] In some embodiments, there are two telescopic rods 102, both of which are disposed on the first plate 105 and the second plate 106.

[0034] In actual use, the purpose of setting two telescopic rods 102 is to better support the first plate 105 and the second plate 106.

[0035] In some embodiments, the telescopic rod 102 includes a slide cylinder 107 and a slide rod 108. The slide cylinder 107 is hinged to the first plate 105, and the first spring 103 is disposed inside the slide cylinder 107. One end of the slide rod 108 is hinged to the second plate 106, and the other end is in contact with the first spring 103 and is damped and slidably connected to the slide cylinder 107.

[0036] In actual use, when the locking structure is opened, the first spring 103 inside the slide cylinder 107 between the first plate 105 and the second plate 106 is no longer compressed. The reaction force of the first spring 103 acts on the slide rod 108, causing the slide rod 108 to slide inside the slide cylinder 107. Furthermore, through the damped sliding connection, the unfolding speed of the first plate 105 and the second plate 106 can be controlled to avoid injury to the user. Since both ends of the slide cylinder 107 and the slide rod 108 are hinged, the slide rod 108 pushes the second plate 106 to unfold, thereby forming a planar structure at the unfolding opening of the first plate 105 and the second plate 106.

[0037] It should be noted that in this embodiment, the damped sliding connection is existing technology. The damped sliding connection means a sliding connection with large friction, which is one of the implementation methods of the sliding connection. This embodiment does not involve any improvement to the damped sliding structure, and will not be described in detail here.

[0038] In some embodiments, the slide cylinder 107 and the slide rod 108 are respectively hinged to the first plate 105 and the second plate 106 via the hinge portion 109.

[0039] In actual use, the purpose of setting the hinge part 109 is to facilitate the installation of the slide cylinder 107 and the slide rod 108. The hinge part 109 is specifically a support seat with holes on the side. The slide cylinder 107 and the slide rod 108 are also provided with holes corresponding to the shaft. After a pin is inserted into the hole, the pin rotates in the hole. The advantage of this setting is that the slide cylinder 107 and the slide rod 108 can be better installed.

[0040] In some embodiments, the first plate 105 and the second plate 106 are hinged together by a hinge 110.

[0041] In actual use, the purpose of setting the hinge 110 is to facilitate the hinge connection between the first plate 105 and the second plate 106.

[0042] In some embodiments, the locking structure includes a first locking component and a second locking component. The first locking component is disposed on the first plate 105, and the second locking component is disposed on the second plate 106. The first locking component is used to lock with the second locking component.

[0043] In actual use, the first locking component engages with the second locking component to fix the first plate 105 and the second plate 106 together.

[0044] In some embodiments, a through groove 111 is provided on the first plate 105, and the first locking component is disposed inside the through groove 111. A groove 112 is provided on the second plate 106, and the second locking component is disposed inside the groove 112. The positions of the through groove 111 and the groove 112 are matched.

[0045] In actual use, the purpose of providing the through groove 111 and the recess 112 is to facilitate the installation of the first locking assembly and the second locking assembly.

[0046] In some embodiments, the first locking assembly includes a column 113, a locking block 114, and a second spring 115. The two ends of the column 113 are respectively mounted on the inner surface of the through groove 111. The second spring 115 is sleeved on the column 113.

A limit buckle 116 is provided on the locking block 114, which is used to fasten to the second locking assembly.

[0047] In some embodiments, the second locking assembly includes a support block 117, on which a locking groove 118 is provided, and the limiting buckle 116 is used to be inserted into the locking groove 118.

[0048] In actual use, when locking the first plate 105 and the second plate 106, the locking block 114 is first pushed to compress the second spring 115, causing the locking block 114 to slide on the column 113. Then, the first plate 105 and the second plate 106 are engaged. When the limiting buckle 116 is inside the groove 112, the locking block 114 is released. The reaction force of the second spring 115 causes the locking block 114 to move the limiting buckle 116 towards the locking groove 118. Finally, the second spring 115 locks the limiting buckle... 116 is pressed tightly into the lock groove 118, completing the locking of the first plate 105 and the second plate 106. When it is necessary to unlock, the operator only needs to push the lock block 114. After the limit buckle 116 on the lock block 114 unlocks from the lock groove 118, the first spring 103 can push the slide bar 108 to push the second plate 106, and finally complete the unfolding of the first plate 105 and the second plate 106. The advantage of this setting is that it is convenient for users to operate the entire locking structure. It is simple to use and easy to operate.
