Description

Technical Field

[0001] The utility model belongs to the technical field of cards with reversible switching of opening and closing states, and in particular relates to a 3D pop-up card with a fabric image. Background Art

[0002] Various embodiments of 3D pop-up cards (hereinafter referred to as 3D cards) have long been known and basically include: a card that is usually simply folded as a base (hereinafter referred to as a card); and an image arranged in the card. The basic function of such a 3D card is that when the folded card is opened, the image, which is initially basically two-dimensionally compressed, rises from the plane of the card in a three-dimensional manner; by unfolding the two foldable card parts by a total of 180° into the same plane, the corresponding 3D card can be opened from a closed state to an extended state. The basic principle of conventional 3D pop-up cards is that the compressed image is fastened in the card in a folded and fitted manner, so that by opening the folded card, a tensile stress is applied to the image, which switches the image from a compressed configuration to a three-dimensional or extended configuration.

[0003] Despite the continuous development of digitalization, 3D cards are still very popular. The demand for new shapes and designs never stops. However, given that digital greeting cards are usually provided free of charge, this has brought huge cost and innovation pressure to the providers of 3D cards. Traditional 3D cards generally use paper or paper-like rigid materials to make three-dimensional images, which are not satisfactory in the final presentation effect. The entertainment, stability and preservation of the three-dimensional images are low, which puts traditional 3D pop-up cards at a disadvantage in the market competition of digital greeting cards. 3D pop-up cards using fabric images solve the disadvantages of using paper or paper-like rigid materials, but the construction of such 3D cards with fabric images requires, on the one hand, the formation of a fabric image that can switch from a compressed two-dimensional state to a three-dimensional state, and on the other hand, the image needs to be fastened inside the card, and the fabric image will not present a stable three-dimensional shape when the card is unfolded, but at least partially folded inward. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies of the prior art, the utility model provides a 3D pop-up card with a fabric image, which solves the technical problems of low entertainment, stability and preservability of the three-dimensional image made of paper or similar rigid materials in traditional 3D cards. At the same time, the technical solution of the utility model is used in the 3D pop-up card with a fabric image to solve the technical problems that the three-dimensional image of the 3D pop-up card cannot be stably supported, the state switching is not smooth, the production cost is high, and the three-dimensional image occupies a large space.

[0005] The utility model is realized by the following technical solutions to achieve the above-mentioned purpose: a 3D pop-up card with a fabric image, comprising a fabric image, the fabric image having a structure that can be reversibly switched from a plane compression state to a three-dimensional extension state; a base with a folding function, the base having a structure that can be reversibly switched from a plane compression state to a three-dimensional extension state; and a foldable card having an inner side and an outer side, the foldable card having a structure that can be reversibly switched from a folded closed state to an unfolded state, wherein the base is fixed to the inner side of the foldable card, and wherein the fabric image is fixed to the base, the foldable card comprises an additional support member, the support member is arranged inside the base and supports the base from the inside when the foldable card is in an unfolded state. The fabric image can be made of any material, and the base is arranged with an additional support member, wherein the support member is preferably arranged on the center line of the foldable card in the base, and wherein the foldable fabric image can be arranged on the base.

[0006] Here, the term "fabric" should be understood in a broad sense, including but not limited to any woven, knitted, braided or other types of textiles. Of course, non-fabric decorations, such as decorations made of metal, plastic or glass, can also be set on the fabric image. At this point, the corresponding decorative options do not need to be listed in detail, and all belong to the technical scope protected by the utility model.

[0007] Preferably, the additional support member is separately fixed to the foldable card.

[0008] Preferably, the material of the additional supporting member is stronger than the material constituting the base.

[0009] Preferably, the base in the extended state is the same basic support structure as the fabric image in the extended state, and the base (5) has a circular bottom surface; that is, if the fabric image is set to be conical, the base is also set to be conical. If the fabric image is set to be cylindrical, the base is also set to be cylindrical, and so on.

[0010] Preferably, the foldable card further comprises: a light element and an acoustic element; a switch for activating the light element and the acoustic element; a circuit or a microprocessor for controlling electronic components; and a power source, other light effects and acoustic effects triggered by opening the card. The foldable card comprises conventional electronic components, such as a power source, a switch, an integrated circuit for controlling the electronic components, and a plurality of light elements and acoustic elements. Preferably, in addition to the light element and the acoustic element, the electronic components are arranged on a circuit board. The preferred light element is an LED, wherein the color and number of the LED can be arbitrary. The preferred acoustic element is a speaker. The light element and the acoustic element are configured to output specific visual and auditory stimuli. A preferred power source is a battery or a rechargeable battery. The switch is used to activate the electronic components when the 3D card is opened, so as to enrich the opening and / or opening state of the image unfolding 3D card through visual and auditory stimulation. Therefore, all types of switches and light sensors or motion sensors that can realize the activation of electronic components by opening the card are suitable. The corresponding switches and sensors are known to those skilled in the art.

[0011] Preferably, the foldable card is divided into two halves, the two halves are configured to be foldable up and down, and the two halves are configured to have a double-layer structure with an inner layer and an outer layer. This double-layer embodiment of the card is conducive to arranging electronic components between the two layers in a sandwich manner and hiding the electronic components in this way.

[0012] Preferably, the double-layer foldable card comprises a card initially composed of four adjacent sections and is obtained by folding. The initial card of the foldable card comprises four sections, namely two outer sections and two inner sections. The initial card of the foldable card is preferably provided in a single piece, which has an outer side and an inner side, but a variant consisting of multiple parts can also be adopted. For example, several, a plurality or all of the sections can only be connected together later, for example by adhesive connection; the contours of the two outer sections and the two inner sections correspond, wherein the outer sections are folded onto the adjacent inner sections respectively. In this way, a double-layer card is obtained, whose visible surface corresponds to the outer side of the initial card, while the inner side of the initial card is located between the folded sections. Therefore, it is sufficient to print only on the outer side of the initial card, so that after the sections are folded, a double-layer card with printing on all visible surfaces is obtained. The inner section of the card comprises openings and slots, so as to fix and place other elements in or on the card, such as bases, supports or other light and sound effect elements.

[0013] As preferably, the base is fixed in an opening and a slot provided for this purpose in the card by means of a fastening element (such as a tab). Alternatively, the base can also be directly arranged on the inner side of the card, for example by gluing the fastening element on the inner side of the card.

[0014] As a preference, the textile image can be fixed to the base by means of known adhesives.When the card is closed, both the three-dimensional textile image and the base switch to a substantially flat two-dimensional structure.

[0015] Preferably, the support comprises a projecting support portion so that when the foldable card is opened, the projecting support portion projects from the fabric image. The projecting portions can be arranged on the reinforcing element or alternatively on the support itself, which can project from the actual contour of the support as described above and in particular only project from the base and respectively from the fabric image when the card is unfolded. That is, when the card is opened, the projecting portion or the element fixed thereto projects from the fabric image. For example, the fabric image can be a cake, and only when the card is opened, the candles fixed to the projecting portion will project from the cake. The candles are correspondingly fixed to the projecting portions of the reinforcing element and / or the support. At the corresponding projecting portions, many other combinations of fabric images and other ideas can be envisaged.

[0016] Preferably, the support member comprises a reinforcing element.

[0017] Preferably, the reinforcing element comprises a main body and a protruding portion such that when the foldable card is opened, the protruding portion protrudes from the fabric image.

[0018] In order to reduce the material of the base as much as possible and still provide sufficient stability, in the construction scheme of the utility model with the base and the additional support, the base is made of a relatively thin but sufficiently rigid material and only the support is made of a relatively stable material, thereby reducing the manufacturing cost. For example, the base can be made of a flexible foil or paper, but the support should be made of a more solid plastic (such as PET) or cardboard, and the rigidity and strength should be sufficient to ensure that the support is folded in a predetermined manner without causing unexpected deformation.

[0019] The support is substantially flat and can be provided as a single piece as a whole. Preferably, the profile of the support corresponds to the axial longitudinal section of the upright base. That is, in the case where the base is in the shape of a pointed cone, the shape of the support is an isosceles triangle, in the case of a blunt cone, it is a trapezoid, in the case of a cube, it is a square, and so on.

[0020] Preferably, the support itself is arranged in at least two parts and comprises, in addition to the actual support described above, a reinforcing element. The reinforcing element is connected to the support and, in the technical solution using the reinforcing element, the material of the support can also be quite thin and, for example, made of paper, since the integral structure formed by the support and the reinforcing element is mainly given the required strength and rigidity by the reinforcing element. The shape of the reinforcing element is consistent with the shape of the support. The support comprises, on the lower side to be connected to the card, a fastening element which enables a stable connection between the support and the card. The support is preferably fixed only to the card. A number of openings can be provided for fastening other elements to the support or for passing them through the support, such as a light element or a corresponding cable.

[0021] Compared with the prior art, the beneficial effects obtained by the utility model are:

[0022] The utility model discloses a 3D pop-up card with a fabric image. When the fabric image is used as the 3D image in the foldable card, the technical problem is how to make the folded fabric image unfold completely and evenly when the card is opened, because the fabric image does not have enough rigidity to independently maintain its three-dimensional shape in the unfolded state simply by relying on its usually quite soft and unstable textile material. The base of the additional support member and the actual three-dimensional fabric image are arranged on the foldable card. The base of the additional support member and the actual three-dimensional fabric image are both foldable elements. The foldable elements can be reversibly switched or transformed from a folded or compressed state to an unfolded or stretched state, and this state change is triggered by opening or closing the foldable card. If the unfolded card forms a plane, that is, the two parts or halves of the card are unfolded at a total angle of 180° and are adjacent in a plane, the card (or 3D card or 3D pop-up card) should be regarded as open. On the contrary, if the two parts or halves of the card are located on top of each other and their inner sides are placed one above the other, the card should be considered closed; the 3D card has an outer side and an inner side, wherein the base is fixed to the inner side, and when the card is closed, the base and the fabric image are located between the inner sides of the folded card, and due to the base and the reinforcing element, the shape of the fabric image in the upright state is significantly more stable, with stronger entertainment, stability and long-term preservation. In addition, through the construction scheme of the utility model with an additionally reinforced base, an extremely material-saving and still stable implementation scheme can be achieved, so that the 3D fabric image support of the 3D pop-up card with the fabric image is more stable when unfolded, and the extension is smoother, saving space in the closed state and the reasonable selection of materials with strength and rigidity can reduce manufacturing costs.
