Description

Technical Field

[0001] This application relates to the field of mobile device accessories, and more particularly to magnetic card holders. Background Technology

[0002] With the widespread adoption of mobile payments and multifunctional smart accessories, cardholder design has evolved from traditional single-function storage to integrated, modular portable solutions. In existing technologies, magnetic cardholders use built-in magnets to attach to smart devices (such as smartphones and tablets), improving portability. These products typically use hinges or pivots for opening and closing, and some designs even integrate support functions to expand usage scenarios. Regarding magnetic circuit layout, early solutions often used evenly distributed or symmetrically arranged magnet slots to provide stable magnetic force; for card securing mechanisms, elastic clips and spring plates are widely used to prevent cards from slipping. Furthermore, to optimize human-computer interaction, card slots and viewing windows have become common features in modern cardholder designs, aiming to improve the efficiency of one-handed card operation. However, these technological improvements still suffer from structural redundancy, insufficient functional synergy, and limited reliability.

[0003] Despite the progress made in existing technologies, their limitations are still evident in the following aspects: First, the layout of magnetic modules often does not fully consider the torque balance in asymmetric adsorption scenarios, which makes the card holder prone to warping or falling off when it is adsorbed to the edge of the device; Second, the rotating connection structure lacks a multi-level limiting mechanism and has a single opening and closing angle, which cannot simultaneously ensure the stability of compact storage and bracket function. Utility Model Content

[0004] This application provides a magnetic card holder to address the problems of insufficient magnetic stability and limited functionality of the opening and closing structure in existing card holder technologies.

[0005] This application provides a magnetic card holder, including a magnetic plate and a card storage bag. The magnetic plate includes a plate body with a magnetic groove on the plate body, a connecting shaft at the top of the plate body, a limiting plate at the top of the connecting shaft, and limiting protrusions on both sides of the connecting shaft.

[0006] The card storage package includes a card slot, a window at the bottom of the card slot, a card pressing plate at the top of the window, a limiting block at the bottom of the window, a card retrieval hole on the side of the card slot away from the magnetic suction plate, a split shaft at the top of the side of the card slot close to the magnetic suction plate, a second limiting plate at the center of the split shaft, and a limiting groove at the bottom of the split shaft.

[0007] The magnetic plate and the card holder are rotatably connected by the cooperation of the connecting shaft and the split shaft. Both the magnetic plate and the card holder have grooves on their outer sides for installing leather.

[0008] As an improvement, a connecting hole is provided at the center of the connecting shaft and the split shaft. The magnetic plate and the card holder are rotatably connected around the connecting hole. In normal state, the magnetic plate and the card holder abut against each other and are limited by one groove of the limiting groove and the limiting protrusion. When needed, the card holder is rotated to the other groove of the limiting groove to cooperate with the limiting protrusion to achieve locking. The bottom of the card holder serves as a support and can be used as a mobile phone stand.

[0009] As an improvement, the magnet groove includes an annular groove, a vertical groove and a bottom groove. The annular groove and the vertical groove are both located on the center line along the length of the plate, and the bottom groove is symmetrically located on both sides of the bottom of the plate. Magnet blocks are installed inside all the grooves.

[0010] As an improvement, the top of the connecting shaft is semi-cylindrical, and the limiting plate is located on the side with the magnet groove. The limiting plate is higher than the connecting shaft. The function of the limiting plate is to limit the rotation angle of the storage bag. When the limiting plate abuts against the second limiting plate, it will be limited.

[0011] As an improvement, the rotation range of the memory card holder starts from the position where the magnetic plate abuts against the memory card holder and extends to the position where the limiting plate abuts against the second limiting plate. This position is used as a mobile phone holder.

[0012] As an improvement, the pressure plate is an elastic plate that protrudes into the card slot. The pressure plates are symmetrically arranged on both sides of the window. The pressure plates are used to hold the cards in place. When there are too few cards in the card slot, the pressure plates can ensure that the cards do not slip out.

[0013] As an improvement, the limiting block and the pressure plate are in the same vertical position and are symmetrically arranged on both sides of the empty window. The limiting block is to prevent the card from sliding out of the empty window after it is inserted to the bottom, thus preventing loss.

[0014] As an improvement, the card retrieval hole is an arc-shaped hole located at the bottom of the card holder on the side away from the magnetic plate. The card retrieval hole is used to push out the card, allowing the card to protrude from the top of the card slot for easy card retrieval.

[0015] As an improvement, the limiting grooves are symmetrically distributed, and each limiting groove consists of two parallel grooves. The limiting grooves cooperate with the limiting protrusions, and the parallel grooves can cooperate with the limiting protrusions to form limiting at two angles.

[0016] As an improvement, in both the closed and open states, the limiting protrusions engage with the grooves of the two limiting slots to form a locking mechanism.

[0017] Compared with existing technologies, the advantages of this invention are as follows: The optimized magnetic circuit design, achieved through annular, vertical, and symmetrically distributed magnet slots at the bottom, significantly improves adsorption stability and anti-warping capability; the innovative rotating connection mechanism, combined with double limiting slots and a raised structure, achieves precise positioning and locking of the opening and closing angle, while also functioning as a flat storage unit and a stable support; the elastic pressure plate and limiting block work together to adapt to different numbers of cards, preventing slippage and detachment; the arc-shaped card retrieval hole design conforms to ergonomics, enabling quick one-handed card retrieval. The overall structure is compact, with high functional integration, effectively solving reliability issues in various application scenarios. Attached Figure Description

A stainless steel rotating shaft with a diameter of 2mm and a length of 15mm is inserted into the connecting hole 131 to ensure smooth rotation.

[0064] Work process and principles

[0065] During the card storage process, the user inserts the card from the card slot 21 of the card storage package 2.

[0066] The card slides along the card slot 21. When the bottom of the card contacts the limiting block 24, it is prevented from moving further, thus preventing the card from sliding out of the empty window 22.

[0067] The pressure plate 23, being elastic, presses down on the top of the card, ensuring the card remains stable within the card slot 21. Even with a small number of cards, such as one, the pressure plate 23 provides sufficient pressure to prevent the card from shifting.

[0068] During the card retrieval process, the user inserts their finger into the card retrieval hole 25 and gently pushes the card upwards, causing the card to emerge from the top of the card slot 21.

[0069] Because of the presence of window 22, users can observe the card's position to assist in retrieving the card.

[0070] The pressure plate 23 elastically deforms when the card is pushed, allowing the card to move, and returns to its original shape after the card is removed.

[0071] In the closed state during opening, closing, and locking: the magnetic plate 1 and the card holder 2 are abutted together via the rotating connecting shaft 13 and the split shaft 26. At this time, the limiting protrusion 15 engages with one of the grooves in the limiting groove 28 to form a lock, preventing accidental opening. The card holder is in a flat state for easy carrying.

[0072] Open state: The user applies force to the memory card holder 2, causing it to rotate around the axis of the connecting hole 131. During rotation, the limiting protrusion 15 slides out from the first groove of the limiting groove 28 and slides along the bottom of the split shaft 26.

[0073] Rotation limit: When the card holder 2 rotates to the point where the limit plate 14 abuts against the second limit plate 27, the rotation is restricted. At this time, the card holder 2 and the magnetic suction plate 1 form a certain angle of about 60°. The limit protrusion 15 cooperates with the other groove of the limit groove 28 to form a second locking.

[0074] As a phone stand: When open, the bottom of the memory card holder 2 serves as a support point, forming a triangular stable structure together with the magnetic plate 1, allowing the phone to be placed on the back of the memory card holder 2, thus realizing the stand function.

[0075] During the magnetic attraction process, the magnet blocks inside the magnetic plate 1 are installed in the magnetic groove 12 to generate a magnetic field, allowing the card holder to be attracted to a metal surface such as a mobile phone case or refrigerator. The layout of the magnetic groove 12, consisting of an annular groove 121, a vertical groove 122, and a bottom groove 123, optimizes the magnetic field distribution and ensures a firm attraction.

[0076] In the overall operation example, the user attaches the wallet to the back of the phone and secures it with the magnetic force of the magnetic plate 1.

[0077] When a card needs to be retrieved, the user pushes the card out through the card retrieval slot 25.

[0078] When the phone needs to be used as a stand, the user opens the memory card holder 2, rotates it to the limit position, and then places the phone on it.

[0079] When closing, gently press the storage card pack 2, and the limiting protrusion 15 slides back into the first slot to achieve locking.

[0080] Key component interaction description: Rotary connection: Connecting shaft 13 and split shaft 26 are connected by a rotating shaft to ensure smooth rotation. The contact between limiting plate 14 and limiting plate 27 determines the maximum rotation angle.

[0081] Limiting mechanism: The cooperation between the limiting protrusion 15 and the limiting groove 28 provides two stable closing and opening positions, and locking is achieved through the interference fit between the protrusion and the groove.

[0082] Flexible card clamping: The flexible design of the card clamping plate 23 ensures that the cards can adapt to different quantities and are always clamped tightly.

[0083] Magnetic attraction optimization: The symmetrical layout of the magnet slot 12 enhances the adsorption stability and avoids uneven magnetic force.

[0084] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
