[0022] Reference Figure 1 , Figure 2 and Figure 3 This utility model proposes a card holder, including a housing 100. The housing 100 has a storage cavity 103 for accommodating cards, providing basic storage space for the cards. A raised plate 110 is provided on the surface of the housing 100. The raised plate 110 serves as the mounting base for the elastic tension band 120 and a supporting structure for fixing items. Its shape and size can be designed according to actual needs, such as being rectangular or trapezoidal. The elastic tension band 120 is interference-fitted to both sides of the raised plate 110, forming a closed-loop structure. This interference fit ensures that the elastic tension band 120 is tightly fixed to both sides of the raised plate 110, ensuring connection stability. The elastic tension band 120 has good elasticity and can automatically adjust according to the size and shape of the stored items, working in conjunction with the raised plate 110 to compress and fix the items.

[0023] The card holder's storage cavity 103 can not only store standard-sized cards but also accommodate large, irregularly shaped cards. When storing large, irregularly shaped cards, conventional card holders often fail to provide a suitable way to secure them due to their irregular shape. However, the elastic tension band 120 of this invention, in conjunction with the raised plate 110, effectively solves this problem. The elastic tension band 120 can adaptively adjust to the contour of the irregularly shaped card, tightly conforming to the card surface. Working together with the raised plate 110, it firmly secures the irregularly shaped card within the card holder, preventing it from shifting or becoming damaged. Furthermore, this card holder can also be used to store other items, such as keys, USB drives, coins, and other small items. These items can also be secured using the elastic tension band 120 and the raised plate 110, ensuring that the items are stored neatly within the card holder for easy access.

[0024] Specifically, the housing 100 is made of high-strength, lightweight plastic and manufactured using injection molding. During manufacturing, the mold dimensions are precisely controlled to ensure that the size of the storage cavity 103 meets the needs of storing standard cards while allowing sufficient space to accommodate larger, irregularly shaped cards. A raised plate 110 is integrally molded onto the surface of the housing 100, and the height of the raised plate 110 is designed to stably support items. The elastic tension band 120 is made of highly elastic rubber and is constructed as a closed loop. During installation, the elastic tension band 120 is interference-fitted along both sides of the raised plate 110, and pressure is applied to ensure a tight fit between the elastic tension band 120 and the raised plate 110. After installation, the tightness of the connection between the elastic tension band 120 and the raised plate 110 is checked to ensure there is no loosening.

[0025] In practical use, a regular card is inserted into the storage cavity 103 through the opening 101 at the top of the housing 100. The card falls naturally into the cavity, and since the size of the storage cavity 103 is adapted to the regular card, the card will not move around much inside. For large, irregularly shaped cards, first insert one end of the card into the storage cavity 103, then adjust the card's position so that the card fits as closely as possible to the raised plate 110. Next, stretch the elastic tension band 120 towards the card, so that the elastic tension band 120 fits tightly against the card surface, and together with the raised plate 110, fixes the irregularly shaped card in the card holder. When it is necessary to store items such as keys or USB drives, place the items on the raised plate 110, and similarly stretch the elastic tension band 120 so that the elastic tension band 120 and the raised plate 110 clamp the items, achieving fixed storage of the items.

[0026] It should be noted that for small items such as keys and USB flash drives, the spacing between the elastic tension band 120 and the convex plate 110 can be adjusted to achieve stable clamping of such items.

[0027] When a card needs to be retrieved, the user places the card holder on a stable surface, ensuring it doesn't wobble. The card is neatly stored in the storage cavity 103 of the card holder, its bottom abutting against a card pusher 200 horizontally positioned at the bottom of the cavity 103. The middle section of the card pusher 200 extends out of the notch 102 at the bottom of the housing 100. The user inserts their finger (usually the index finger or thumb) into the notch 102, contacting the protruding part of the card pusher 200. Then, a gentle horizontal push is applied towards the opening 101, pushing the card out. When the card extends a certain length out of the opening 101 and can be easily grasped by the user, the user stops pushing the card, pinches the edge of the card with their fingers, and completely removes the card from the card holder.

[0028] Understandably, the card holder proposed in this utility model breaks through the limitation of traditional card holders that can only store regular cards. Its storage cavity 103 can accommodate large-sized irregularly shaped cards, meeting users' needs for storing special cards. Simultaneously, the design of the elastic tension band 120 combined with the convex plate 110 allows the card holder to also store other items such as keys, USB drives, and coins, realizing the diversification of the card holder's storage function and providing users with a more convenient way to manage their items. During use, users only need to simply stretch the elastic tension band 120 to complete the storage and fixation of items; the operation is simple and easy to understand, requiring no complicated steps or tools. Moreover, the card holder's structural design is reasonable; the positions of the opening 101 and the storage cavity 103 facilitate users to quickly retrieve and place items, improving efficiency. It is suitable for various scenarios. Whether for daily travel, business activities, or special occasions, users can use this card holder to store and manage their cards and items, meeting the needs of different users in different scenarios.

[0029] Reference Figure 1 It should be noted that the card holder housing 100 is manufactured using injection molding. For plastic housings 100, a cavity shaped like a notch 102 is pre-designed in the center of the bottom of the housing 100 during mold design. During injection molding, the molten plastic fills the mold cavity, and after cooling and solidification, the notch 102 naturally forms in the center of the bottom of the housing 100. For metal housings 100, the position of the notch 102 is determined on the metal sheet using a stamping process, and then the sheet is stamped using a stamping die to punch the notch 102 in the center of the bottom of the housing 100. Placing the notch 102 in the center of the bottom of the housing 100 ensures more even force distribution when placing and retrieving cards. When users push cards through the notch 102, the card holder will not wobble or be damaged due to misalignment of the notch 102, improving the stability and lifespan of the card holder. At the same time, this symmetrical layout conforms to user operating habits and enhances the user experience.

[0030] Furthermore, the notch 102 includes a longitudinal notch 102A and a transverse notch 102B. In specific manufacturing, for plastic materials, the notch 102 is formed using a slider structure in the mold. First, the shape and size of the longitudinal notch 102A and the transverse notch 102B are designed. Corresponding sliders are then set in the mold. When the molten plastic is injected into the mold cavity, the longitudinal notch 102A and the transverse notch 102B are formed by the movement of the sliders. For the metal shell 100, a combination of stamping and cutting processes is used. First, a stamping die is used to punch out the approximate shape of the notch 102. Then, a cutting tool, such as a laser cutter, is used to precisely cut out the longitudinal notch 102A and the transverse notch 102B, ensuring that the dimensions of the notch 102 meet the design requirements.

[0031] The vertical notch 102A allows the card to pass through and abut against the inner bottom wall of the housing 100, providing stable support and positioning for the card and making it more neatly placed within the storage cavity 103. The horizontal notch 102B provides clearance for pushing the bottom of the card, allowing users to easily remove the card by pushing it with their fingers or other tools. This combination of notches 102 ensures both the stability of card storage and improves the convenience of card retrieval.

[0032] Optionally, the notch 102 can be trapezoidal, triangular, or rectangular. The triangular notch 102, composed of two longitudinal notches 102A, offers good structural stability, can withstand greater external forces, and is less prone to damage. Simultaneously, the triangular shape provides guidance when pushing the card, making it easier to move along the predetermined direction. The trapezoidal structure, wider at the top and narrower at the bottom, facilitates the insertion of fingers or other tools to push the card while also limiting the card's range of movement to some extent, preventing it from slipping during pushing. The rectangular notch 102 has a relatively simple manufacturing process and lower cost. Furthermore, its regular shape facilitates user operation, allowing for accurate pushing of the card's bottom to remove it.

[0033] Reference Figure 3The bottom of the housing 100 is fitted with a card pusher 200 via a pivot hole 210. The card pusher 200 is a long, strip-shaped plastic piece positioned horizontally at the bottom of the storage cavity 103, with its middle section extending beyond a notch 102. When a card is placed in the storage cavity 103, the bottom of the card rests on the card pusher 200, abutting against it. To remove the card, the user pushes the middle section of the card pusher 200 extending beyond the notch 102, causing the card pusher 200 to rotate around the pivot 210, thus moving the card towards the opening 101 and ultimately allowing it to extend out of the opening 101. The card pusher 200 makes card removal more convenient and effortless. Users do not need to directly contact the bottom of the card; simply pushing the card pusher 200 removes the card, avoiding potential damage or soiling caused by direct finger contact.

[0034] Specifically, one end of the push card component 200 is rotatably connected to the housing 100 via a rotating shaft 210. A torsion spring is used as the reset component; it is fitted onto the rotating shaft 210, with one end fixed to the housing 100 and the other end connected to the push card component 200. When the push card component 200 is pushed to rotate and push a card, the torsion spring undergoes torsional deformation, generating elastic potential energy. When the push card component 200 is released, the torsion spring returns to its original shape, causing the push card component 200 to rotate in the opposite direction around the rotating shaft 210, thereby resetting the push card component 200 and preparing it for the next card pushing operation. The reset component allows the push card component 200 to automatically reset after pushing a card, eliminating the need for manual restoration by the user, thus improving the convenience and automation of the card holder. Furthermore, the torsion spring, as a reset component, has a simple structure, low cost, and provides a stable reset force, ensuring the accuracy and reliability of the push card component 200's reset.

[0035] Furthermore, the card pusher 200 has several steps 220 machined on the side facing the opening 101. The height and spacing of the steps 220 are designed according to the thickness and number of cards. When multiple cards are placed into the storage cavity 103, the bottom of each card abuts against a different step 220. When the card pusher 200 is pushed, each step 220 pushes the corresponding single card. Due to the different heights of the steps 220, the cards are arranged in a staggered manner at different heights in the vertical direction when they extend out of the opening 101. This design allows multiple cards to be staggered when they extend out of the opening 101, making it convenient for users to quickly identify and select the required cards. It avoids the problem of multiple cards blocking each other and being difficult to distinguish when they extend out of the opening 101 at the same time, thus improving the efficiency and accuracy of card retrieval.

[0036] Understandably, when using a card holder equipped with a card pusher 200, the user places the card holder on a stable surface to ensure it doesn't wobble. At this time, the card is neatly stored in the storage cavity 103 of the card holder, its bottom abutting against the card pusher 200 horizontally positioned at the bottom of the storage cavity 103. The middle section of the card pusher 200 extends out of the notch 102 at the bottom of the housing 100. The user inserts a finger (usually the index finger or thumb) into the notch 102, contacting the protruding part of the card pusher 200. Then, a gentle horizontal push is applied towards the opening 101, causing the card pusher 200 to rotate around the pivot 210 connected to the housing 100. Because the card pusher 200 abuts against the bottom of the card, its rotation causes the card to move upwards. The card rises smoothly along the inner wall of the storage cavity 103, gradually approaching the opening 101 of the card holder. When the card extends a certain length from the opening 101 and can be easily grasped by the user, the user stops pushing the card pusher 200, pinches the edge of the card with their fingers, and completely removes the card from the card holder. If the card pusher 200 of the card holder is connected to a reset mechanism, the reset mechanism will activate after the user stops pushing the card pusher 200. The elastic force generated by the stretching or compression of the spring, or the torque of the torsion spring, will cause the card pusher 200 to automatically rotate in the opposite direction around the pivot 210, returning to its initial position, preparing for the next card push operation.

[0037] Reference Figure 2 and Figure 3 A plurality of buffer wheels 130 are evenly installed on the inner wall of the housing 100 through mounting holes. The buffer wheels 130 are made of rubber and have a certain degree of elasticity. The buffer wheels 130 are positioned on the inner wall of the housing 100 on the corresponding sides of the card. When the card extends out of the opening 101 under the action of the pusher 200, the two sides of the card abut against the buffer wheels 130. The buffer wheels 130 roll during the movement of the card, and their elasticity slows down the movement speed of the card. The buffer wheels 130 effectively slow down the speed at which the card extends out of the opening 101, preventing the card from falling or being damaged due to rapid extension. At the same time, the rubber buffer wheels 130 provide a certain degree of cushioning, reducing the collision and friction between the card and the housing 100, protecting the card surface from damage, and extending the card's service life.

[0038] Reference Figure 2 and Figure 3In some embodiments, limiting inclined walls 140 are formed on both sides of the opening 101. The limiting inclined walls 140 are inclined from both sides of the housing 100 toward the opening 101. By precisely controlling the inclination angle and size of the mold, the width of the opening 101 matches the width of the card. When the card is placed into the storage cavity 103 and extends out of the opening 101, the limiting inclined walls 140 restrict the horizontal movement of the card, preventing it from detaching from the opening 101. The design of the limiting inclined walls 140 ensures that the width of the opening 101 is adapted to the width of the card, guaranteeing that the card can smoothly extend and retract into the opening 101 while effectively limiting the card's range of movement, preventing the card from falling out, and improving the card holder's protective performance and safety.

[0039] In some embodiments, a magnetic clasp is attached to one side surface of the housing 100 by adhesive or embedding, and the magnetic clasp is a strong magnet. When the user needs to carry the card holder with the mobile device, bringing the card holder close to the mobile device allows the magnetic force generated by the magnetic clasp to attract the card holder to the mobile device, achieving a convenient connection between the card holder and the mobile device. The magnetic clasp makes it easy for the card holder to attach to the mobile device, facilitating user carrying and management. Users do not need to use additional tools or accessories to secure the card holder, reducing the number of items to carry and the hassle, thus improving convenience and practicality. Furthermore, the magnetic connection is secure and reliable, and is not easily detached.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
