Description

Technical Field

[0001] This application relates to the field of electronic device accessories, and in particular to a four-in-one double-layer card slot. Background Technology

[0002] With the rapid development of mobile communication technology, portable smart terminals such as mobile phones and tablets have become an indispensable part of people's daily lives. These devices are not only constantly improving in performance but also continuously optimizing in terms of functional diversity. To meet the diverse communication needs of users, multi-SIM multi-standby functionality has emerged as one of the important means to improve user experience. Traditional single SIM card slots can no longer meet the requirements of modern consumers for convenience and flexibility, especially in multi-SIM application scenarios, where users hope to manage multiple SIM cards and memory cards of different specifications on one device at the same time to improve the efficiency and convenience of device use.

[0003] Existing multi-card solutions mainly include single-layer multi-card slot designs and physically switchable dual-layer card slot designs. Single-layer multi-card slots achieve multi-card support by reducing the space of a single card slot, but due to size limitations, it's difficult to achieve simultaneous insertion of four cards, and operation is inconvenient. Physically switchable dual-layer card slots allow the same slot to be used for different types of cards through a manual switching mechanism. While supporting more types of cards, the switching process can easily damage internal contact points, leading to problems such as insensitive recognition. Although these two solutions alleviate the pressure of multi-card demand to some extent, they still have significant limitations and potential risks.

[0004] These traditional solutions often focus solely on functionality, neglecting user convenience and security during actual use. These issues severely impact the user experience. Therefore, existing technologies need improvement based on these problems. Utility Model Content

[0005] The purpose of this application is to provide a four-in-one double-layer card holder.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a four-in-one double-layer card holder, comprising an upper body and a lower body, wherein the upper body and the lower body together form an installation groove, a card holder is provided in the installation groove, the card holder is recessed with a first card groove on the side near the upper body, and the card holder is recessed with a second card groove, a third card groove and a fourth card groove on the side near the lower body respectively; the upper body is provided with an upper terminal, and the lower body is provided with a lower terminal.

[0007] By adopting the above technical solution, the device can simultaneously support multiple different types of cards within a single card slot, greatly improving its versatility and meeting users' diverse communication and storage needs. Its dual-layer structure design makes efficient use of space, effectively solving the problem of traditional single-layer multi-card slots being unable to accommodate four cards simultaneously due to size limitations, providing users with a wider range of card configuration options. Simultaneously, the coordinated layout of the upper and lower main bodies, card trays, upper and lower terminals ensures precise cooperation between components, laying the foundation for stable electrical connections and improving data transmission reliability.

The handle makes the insertion and removal of the card tray more standardized and stable, effectively avoiding problems such as card tray tilting, jamming, or collision with internal components of the card holder that may be caused by directly pushing or pulling the card tray, thereby reducing the risk of damage to the card holder and cards and extending the service life of the product.

[0016] Optionally, the first card slot, the second card slot, the third card slot, and the fourth card slot are all provided with card-holding protrusions on their slot walls.

[0017] By adopting the above technical solution, the card-holding protrusion can closely fit the edge of the card, providing a stable and appropriate clamping force. This ensures that cards of various sizes are reliably fixed in the card slot without external interference, effectively preventing cards from accidentally falling off due to device movement or vibration. It guarantees a stable electrical connection between the device and the card, maintaining normal device operation. This avoids contact problems caused by loose cards, reduces the risk of data transmission interruptions or errors, and improves the overall reliability and performance stability of the device. The card-holding protrusion also provides some positioning and guidance for the card, facilitating accurate card insertion and making card insertion and removal smoother and more efficient. This further optimizes the user experience of using multi-card devices and enhances the practicality and ease of use of the product in multi-card management.

[0018] Optionally, the upper terminal is provided with a plastic fixing component for fixing the solder joint of the upper terminal.

[0019] By adopting the above technical solution, the plastic fastener provides reliable support and protection for the solder feet of the upper terminals, effectively preventing deformation, displacement, or breakage of the solder feet under external impact, vibration, or long-term use. This ensures a stable and reliable electrical connection between the solder feet and the PCB board, greatly improving the stability and continuity of data transmission and reducing the risk of signal interruption or equipment failure due to poor contact. Simultaneously, the insulating properties of the plastic fastener prevent short circuits between solder feet or accidental conduction with other metal components, further enhancing circuit safety and stability and ensuring the normal operation of the equipment.

[0020] Optionally, the head of the lower terminal is embedded within the lower body.

[0021] By adopting the above technical solution, the embedded structure greatly enhances the connection stability between the lower terminal and the lower body, effectively preventing the lower terminal from loosening, shifting, or falling off due to external forces such as equipment vibration, collision, or frequent card insertion and removal during daily use. This ensures that the lower terminal is always in a precise and stable position inside the card holder, thereby guaranteeing a reliable electrical connection with the card and providing a solid guarantee for stable data transmission. The embedded design also provides excellent protection for the head of the lower terminal, preventing it from being corroded by external dust, moisture, and other impurities, as well as accidental physical damage. This reduces the probability of poor contact or functional failure due to terminal damage, extending the service life of the lower terminal and the entire card holder. Furthermore, this structure helps optimize the internal space layout of the card holder, making the fit between the lower body and the lower terminal more compact and reasonable. This creates favorable conditions for the installation of other components and the miniaturization of the overall structure, improving the product's integration and space utilization. This allows the card holder to achieve more functions and maintain good performance within a limited space.

[0022] Optionally, the upper terminal includes a mounting portion, which extends toward the mounting groove to form a connecting portion, and the connecting portion and the mounting portion are set at a certain angle.

[0023] By adopting the above technical solution, the mounting part and the connecting part are set at a specific angle to form a clever mechanical structure. When the card tray tilts or shifts during insertion, potentially causing it to tip over, the connecting part, due to its angle relationship with the mounting part, can provide just the right amount of resistance and guidance to the card tray. This structure acts like a precise guide device, promptly correcting the card tray's incorrect posture and ensuring it is smoothly inserted into the mounting slot in the correct direction. This effectively avoids damage to the internal structure of the card holder caused by the card tray tipping over, as well as problems such as poor card contact and electrical connection interruption. This not only improves the first-time success rate of card tray insertion, reducing the hassle of repeated attempts due to card insertion failures, but also ensures a stable and reliable electrical connection between the upper terminal and the card on the card tray, guaranteeing the continuity and stability of data transmission. This provides users with a more convenient, efficient, and reliable multi-card usage experience, while also improving the overall durability and stability of the card holder and extending the product's lifespan.
