Description

Technical Field

[0001] This utility model belongs to the field of daily necessities technology, specifically relating to a spring-loaded card holder. Background Technology

[0002] In daily life, people generally need to carry and manage various cards, including bank cards, credit cards, ID cards, membership cards, and transportation cards. These cards are not only related to personal financial security and identity verification, but also closely related to the convenience of daily life. Although commonly used soft plastic or leather card holders are lightweight and portable, they have obvious shortcomings in actual use.

[0003] Traditional card holders, made of soft materials, lack sufficient pressure resistance. When subjected to external pressure, they cannot effectively distribute pressure, causing internal cards to deform or even bend. This not only affects aesthetics and shortens lifespan but may also damage magnetic stripes or chips. Furthermore, the haphazardly stacked card design forces users to search through cards one by one when a specific card is needed, which is particularly inefficient in emergency situations.

[0004] Existing rigid metal card holders are bulky and heavy, significantly exceeding the average weight of similar products, making them less flexible to operate, cumbersome in the interaction process, and lacking in smoothness and portability.

[0005] Based on these pain points, there is an urgent need to design a revolutionary card holder product: utilizing high-strength, lightweight metal materials to ensure pressure resistance, and employing a scientifically designed structure to distribute external pressure; simultaneously, it is equipped with an intelligent arrangement system to achieve card classification, positioning, and quick retrieval. This design not only effectively protects the integrity of the cards but also significantly improves retrieval efficiency, meeting modern people's dual needs for functionality and convenience in everyday items.

[0006] Chinese utility model patent CN220045126U discloses a convenient ejectable card holder, comprising: a card holder body, a pushing component inside the card holder body, the pushing component including a pressing member, one end of the pressing member connected to the pushing member, a connecting post connected to one side of the pushing member, a movable groove adapted to the connecting post at one end of the pressing member, and a torsion spring connecting the pressing member and the card holder body. This utility model provides a convenient ejectable card holder where the pressing member with the movable groove, the pushing member with the connecting post, and the torsion spring work together inside the card holder body. The pressing member presses the card holder body inward, ejecting cards from inside the card holder body to the outside. The ejected cards are stepped, facilitating card identification and retrieval by the user. Simultaneously, the pressing member quickly returns to its original position under the action of the torsion spring. The movable groove of the pressing component is movably connected to the connecting post of the pushing component. Pressing the pressing component drives the pushing component to move, thus realizing the card ejection operation. However, prolonged sliding between the movable groove and the connecting post can cause wear or breakage of the movable groove, preventing the pressing component from driving the pushing component and damaging its card ejection function, thus affecting its service life. Furthermore, the card holder body is a split design, making it bulky and significantly heavier than the average weight of similar products. This makes its operation less flexible, the interaction process cumbersome, and lacking in smoothness and portability. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1:

[0035] This utility model provides a spring-loaded card holder, comprising a hollow cavity body 1 with an assembly port 2. The cavity body 1 is manufactured using an integrated extrusion profile molding process. A plastic part 3 is fixedly installed on the cavity body 1, and a push-card component 4 is movably installed on the plastic part 3. The push-card component 4 includes a card holder section 5 and an abutting section 6. A button 7 is movably installed on the assembly port 2, and the button 7 has a push part 8 with an inclined surface 9 that movably abuts against the abutting section 6. The engagement angle of the inclined surface 9 is 15°-45°. A first connecting rod 27 and a second connecting rod 28 are fixedly installed on the cavity body 1, and a card strap 29 is fixedly installed between the first connecting rod 27 and the second connecting rod 28. The plastic part 3 is fixedly connected to the cavity body 1 by a buckle or screw. A first clamping assembly 14 and a second clamping assembly 15 are fixedly installed on the cavity body 1, and either the first clamping assembly 14 or the second clamping assembly 15 has a first screw through hole 32. The plastic part 3 has second screw through holes 34 on both sides. The plastic part 3 has an extension 18, which has a first shaft 19. The first clamping assembly 14 has a second shaft 20, and a decompression wheel 21 is movably installed between the first shaft 19 and the second shaft 20. The extension 18 has a rectangular groove 33, the length of which is greater than 5 mm. The button 7 has a connecting shaft 22, and the second clamping assembly 15 has a clamping part 23, which is movably connected to the connecting shaft 22. The push-card component 4, located between the card tray section 5 and the abutting section 6, has a reinforcing member 24 with a through hole 25. The plastic part 3 has a shaft 26, and the through hole 25 is movably connected to the shaft 26. The button 7 has an anti-slip texture 30.

[0036] Through the above technical solution, the cavity body 1 of this utility model has rigidity. The card is placed inside the cavity body 1. The user presses the button 7 to push the card pusher 4 to push the card out of the cavity body 1, making it easy for the user to take it out. The rigidity of the cavity body 1 protects the card inside the cavity body 1 and prevents the card from deforming.

[0037] The card-pushing component 4 of this utility model includes a card tray section 5 and an abutment section 6. The card tray section 5 is provided with a bracket 31, which is a stepped structure for arranging cards. This allows the cards placed in the cavity body 1 to be abutted one by one, so that the card-pushing component 4 pushes the cards out in a staggered manner, making it convenient for the user to take them out. When a card needs to be taken out, the user presses the button 7, which pushes the abutment section 6 of the card-pushing component 4 to move, causing the card tray section 5 to push the card out of the cavity body 1, making it convenient for the user to take out the card.

[0038] Example 2:

[0039] In this embodiment, the cavity body 1 adopts a rigid structural design and is manufactured using a one-piece extrusion profile molding process. This manufacturing process ensures that the cavity body 1 has sufficient structural strength and integrity. The cavity body 1 is formed by extrusion molding of aluminum or magnesium alloy profiles. Aluminum or magnesium alloy profiles significantly reduce the overall weight of the card holder, while their inherent high strength ensures that the cavity body 1 maintains its structural integrity under external forces. The extrusion molding process results in a uniform wall thickness distribution for the cavity body 1, maintaining overall rigidity while reducing weight.

[0040] The cavity body 1 has a hollow chamber inside to accommodate multiple cards. An assembly port 2 is provided on one side of the cavity body 1. A plastic component 3 is fixedly installed inside the cavity body 1, and a card pusher component 4 is movably installed on the plastic component 3. This card pusher component 4 adopts a one-piece molding design and includes two interconnected parts: a card tray section 5 and a contact section 6. The end of the card tray section 5 has a stepped bracket 31 structure, which can arrange multiple cards in layers within the cavity body 1. The contact section 6 is linked to the button 7 mechanism.

[0041] A button 7 assembly is movably installed at the assembly port 2. This button 7 features a protruding design for easy pressing by the user. Inside the button 7 is a pusher 8 structure, extending towards the interior of the cavity body 1 and forming a slope 9 at a specific angle. This slope 9 maintains active contact with the abutting section 6 of the push-card component 4. When an external force is applied to press the button 7, the slope 9 moves along a specific trajectory and exerts a pushing force on the abutting section 6. The push-card component 4 employs a lever structure design; the movement of the abutting section 6 directly drives the synchronous movement of the card tray section 5. During movement, the stepped bracket 31 of the card tray section 5 sequentially pushes the arranged cards, causing them to extend out of the assembly port 2 in a staggered manner, forming an arrangement convenient for the user to grasp.

[0042] The working principle of this embodiment is based on rigid transmission and a stepped card-pushing mechanism. When the user needs to retrieve a card, they only need to press button 7 once. The inclined surface 9 of the push part 8 of button 7 will push the abutment section 6. The card-pushing component 4 adopts a lever structure design, and the movement of the abutment section 6 will directly drive the card tray section 5 to move synchronously. Due to the stepped design of the tray 31, the cards placed in the cavity body 1 are abutted one by one, causing the card-pushing component 4 to push the cards out in a staggered manner. The cards pushed out of the cavity body 1 are also arranged in a stepped manner, making it easier for the user to identify and retrieve the cards.

[0043] Regarding card protection, this embodiment effectively disperses external pressure through the rigid cavity body 1 structure. When the card holder is compressed, the rigid material can evenly transmit the external force to the entire cavity body 1, avoiding localized stress concentration that could lead to card deformation. The plastic parts 3 and the card pushing components 4 inside the cavity body 1 together form a stable support frame, ensuring that the card remains flat during storage and carrying.

[0044] Example 3:

[0045] In this embodiment, a flexible reset mechanism enables convenient card ejection and automatic reset. When the user presses button 7, the push part 8 of button 7 contacts the abutting section 6 of the card pusher 4 via the inclined surface 9, pushing the card pusher 4 to move. The card tray section 5 of the card pusher 4 adopts a stepped structure design, which can arrange the cards in the cavity body 1 in layers and eject them sequentially. During the movement of the card pusher 4, the connector 10 on the plastic part 3 is connected to the connecting hole 11 of the card pusher 4 via the tension spring 13, and the tension spring 13 is stretched and stores elastic potential energy.

[0046] When the user releases button 7, the tension spring 13 releases its stored elastic potential energy, pulling the card pusher 4 back to its original position. The resetting motion of the card pusher 4 interacts with the inclined surface 9 of the pusher 8 of button 7 via the abutting section 6, causing button 7 to synchronously reset to its initial position. This linkage mechanism ensures that the card holder automatically returns to its standby state after use, without requiring manual adjustment. The elastic connection of the tension spring 13 not only achieves stable resetting of the card pusher 4 but also avoids rigid collisions in the mechanical structure, extending the lifespan of the card holder.

[0047] The card tray section 5 of the card pusher 4 adopts a stepped bracket 31 design, which can arrange multiple cards in layers. When the card pusher 4 moves, the card tray section 5 pushes each layer of cards in sequence, causing them to extend out of the assembly port 2 of the cavity body 1 in a staggered manner, making it convenient for the user to select the required card.

[0048] The card holder in this embodiment is particularly suitable for scenarios requiring frequent use of multiple cards, such as payments, identity verification, or membership management. Its innovative flexible reset structure and stepped card tray design solve the pain points of traditional card holders, such as poor pressure resistance and inconvenient card retrieval, providing users with an efficient and reliable solution for carrying and managing cards.

[0049] Example 4:

[0050] In this embodiment, the cavity body 1 has a hollow structure with rigid protection function. A first clamping assembly 14 and a second clamping assembly 15 are provided on both sides inside the cavity body 1. Each clamping assembly is provided with a first screw through hole 32 and an elastic element 16.

[0051] The first screw through hole 32 facilitates the clamping assembly to be fixedly installed inside the cavity body 1.

[0052] The elastic element 16 has a protrusion 17 structure. When a standard-sized card is inserted along the assembly port 2, the edge of the card simultaneously contacts the protrusion 17 of the elastic elements 16 on both sides.

[0053] During card insertion, the side of the card comes into contact with the protrusion 17, generating an interaction force. Under the force, the elastic element 16 undergoes elastic bending deformation, and the protrusion 17 generates sliding friction along the edge of the card. The restoring force of the elastic element 16 keeps the protrusion 17 in close contact with both sides of the card, fixing the card in place within the cavity body 1.

[0054] When a card needs to be removed, the user presses the button 7 component on the side of the cavity body 1. The push part 8 of the button 7 drives the card pusher 4 to move through the inclined plate mechanism, and the stepped bracket 31 of the card tray section 5 pushes the clamped card in sequence, making it easy for the user to take it out.

[0055] This embodiment features a specially designed contact surface shape for the protrusion 17. The top of the protrusion 17 adopts an involute curved surface transition, forming a smooth force gradient when the card is inserted, avoiding localized stress concentration that could lead to card wear. Simultaneously, the symmetrical arrangement of the card clamping assemblies on both sides creates mechanical balance, ensuring uniform force on the card and preventing bending deformation caused by excessive pressure on one side.

[0056] In extreme cases, such as when the cavity body 1 is subjected to external impact, the rigid cavity body 1 and the elastic clamping assembly form a dual protection mechanism. The outer shell of the cavity body 1 disperses and absorbs most of the impact energy, while the internal elastic element 16 buffers the remaining vibration through deformation, preventing the impact force from being directly transmitted to the card.

[0057] Example 5:

[0058] In this embodiment, the cavity body 1 adopts a hollow design, forming an internal cavity for accommodating cards. An assembly port 2 is provided on one side of the cavity body 1 for mounting the button 7. A plastic component 3 is fixedly installed inside the cavity body 1. A card-pushing component 4 is movably mounted on the plastic component 3, including a card holder section 5 and an abutting section 6. The card holder section 5 carries and pushes the card, and the abutting section 6 cooperates with the push part 8 of the button 7 to push the card out. The button 7 is installed at the assembly port 2, and its push part 8 has a slope 9. When the button 7 is pressed, the slope 9 acts on the abutting section 6 of the card-pushing component 4, causing the card holder section 5 to move, thereby pushing the card out of the cavity body 1 for easy access by the user.

[0059] The first card clamping assembly 14 and the second card clamping assembly 15 are respectively disposed on both sides of the opening of the cavity body 1 for clamping and fixing cards. Both the first card clamping assembly 14 and the second card clamping assembly 15 are provided with elastic elements 16, and the elastic elements 16 are provided with protrusions 17. When the card is inserted into the cavity body 1, the two sides of the card press against the protrusions 17, causing the elastic elements 16 to undergo elastic deformation. The protrusions 17 abut against the two sides of the card, ensuring that the card is firmly fixed in the cavity body 1 and preventing the card from accidentally slipping out.

[0060] An extension 18 is provided on one side of the plastic part 3. The extension 18 can be connected to the plastic part 3 by integral injection molding or secondary splicing and fixing. The extension 18 is set to fit against the inner wall of the cavity body 1 and is located on the same side as the first clamping assembly 14. A first shaft 19 is provided on the extension 18, and a second shaft 20 is provided on the first clamping assembly 14. A pressure relief wheel 21 is movably installed between the first shaft 19 and the second shaft 20. The pressure relief wheel 21 can rotate freely and can be turned by the user with their fingers to relieve stress.

[0061] During use, the user inserts the card into the cavity body 1, and the elastic elements 16 of the first card clamping assembly 14 and the second card clamping assembly 15 automatically clamp the card, ensuring secure storage. When the card needs to be removed, the user presses the button 7. The push part 8 of the button 7 pushes the abutting section 6 of the card pushing component 4, causing the card tray section 5 to move and push the card out of the cavity body 1 for easy access. Simultaneously, the user can release the pressure by turning the decompression wheel 21, enhancing the user experience.

[0062] The card holder in this embodiment has a compact structure and is easy to operate. It can effectively protect the cards from being squeezed and deformed, and can also quickly retrieve the cards. In addition, the design of the decompression wheel 21 enhances the fun and practicality of the product.

[0063] In this embodiment, the extension 18 is provided with a rectangular groove 33, the length of which is greater than 5 mm. The rectangular groove 33 is used to reduce the weight of the extension 18, thereby reducing the overall weight of this invention. At the same time, the optimized structure of the rectangular groove 33 improves the strength of the extension 18.

[0064] Example 6:

[0065] In this embodiment, button 7 is provided with a connecting shaft 22, and the second clamping assembly 15 is provided with a clamping part 23, which is movably connected to the connecting shaft 22. The clamping part 23 has a Y-shaped design, which facilitates the connecting shaft 22 to be snapped into the clamping part 23 during assembly. Through the cooperation between the clamping part 23 and the connecting shaft 22, the flexibility and feel of pressing button 7 are improved.

[0066] In practical implementation, the connecting shaft 22 of button 7 and the clamping part 23 of the second clamping assembly 15 form a movable connection structure. The Y-shaped design of the clamping part 23 gives it two symmetrically distributed clamping arms, forming a receiving space between the two clamping arms, along which the connecting shaft 22 can rotate. When button 7 is pressed, the connecting shaft 22 rotates within the clamping part 23, fixing one end of button 7 while the other end abuts against the abutting section 6 of the push-card component 4. Through the cooperation between the connecting shaft 22 and the clamping part 23, the movement trajectory of button 7 is ensured to be stable, avoiding deviation or jamming, and improving the flexibility and feel of pressing button 7.

[0067] Example 7:

[0068] In this embodiment, the cavity body 1 adopts a hollow design, forming an internal cavity for accommodating cards. An assembly port 2 is provided on one side of the cavity body 1 for mounting the button 7. A plastic part 3 is fixedly installed inside the cavity body 1, and a card-pushing component 4 is movably installed on the plastic part 3. The card-pushing component 4 includes a card holder section 5 and an abutment section 6. The card holder section 5 is used to support and push the card, and the abutment section 6 is used to receive the pushing force of the button 7. The button 7 is movably installed in the assembly port 2. The button 7 has a pushing part 8, which has an inclined surface 9. The inclined surface 9 movably abuts against the abutment section 6. When the button 7 is pressed, the pushing part 8 pushes the abutment section 6, causing the card-pushing component 4 to move as a whole, thereby driving the card holder section 5 to push the card out of the cavity body 1.

[0069] The push-card component 4 has a reinforcing member 24 between the card holder section 5 and the abutment section 6. The reinforcing member 24 has a through hole 25, and the plastic part 3 has a corresponding shaft 26. The through hole 25 and the shaft 26 are movably connected to form the lever fulcrum of the push-card component 4. When the button 7 is pressed, the inclined surface 9 of the push part 8 acts on the abutment section 6, causing the push-card component 4 to rotate around the shaft 26. The card holder section 5 moves accordingly, pushing the card out of the cavity body 1. The reinforcing member 24 enhances the deformation resistance of the through hole 25 area, ensuring that the push-card component 4 maintains stability and reliability during long-term use.

[0070] The card holder section 5 of the card pusher component 4 is equipped with a stepped bracket 31, which is used to arrange the cards, keeping them staggered within the cavity body 1. When the card pusher component 4 moves, the stepped bracket 31 pushes the cards sequentially, causing them to be pushed out one by one in a staggered manner, making it easy for the user to pick them up. The abutment section 6 cooperates with the inclined surface 9 of the pusher part 8 to ensure effective transmission of the pushing force and prevent the card pusher component 4 from jamming or deforming due to uneven force. The cooperation between the through hole 25 of the reinforcing component 24 and the shaft 26 not only provides a lever fulcrum but also restricts the movement trajectory of the card pusher component 4, making it move stably in a predetermined direction and improving the accuracy of card pushing.

[0071] In this embodiment, the spring-loaded card holder significantly enhances the structural strength of the card-pushing component 4 through the reinforcement component 24, making it less prone to deformation or damage during frequent use. The cooperation between the through hole 25 and the shaft 26 forms a stable lever structure, making the card-pushing action smoother and reducing frictional wear. Simultaneously, the stepped bracket 31 optimizes the card arrangement, ensuring that cards can be pushed out quickly and accurately, improving ease of use. The rigid structure of the cavity body 1 effectively protects the internal cards, preventing external pressure from causing card deformation or damage, thus meeting the user's dual needs for card protection and usage efficiency.

[0072] This embodiment of the ejector-type card holder is suitable for storing and managing various types of cards, such as bank cards, ID cards, and transportation cards. Its simple and reliable structure and convenient operation effectively solve the problems of poor pressure resistance and inconvenient card retrieval associated with traditional card holders. By optimizing the lever structure and reinforcing the design of the card pusher component 4, long-term stability and durability are ensured, providing users with an efficient and secure card management solution.

[0073] Example 8:

[0074] In this embodiment, the cavity body 1 adopts a hollow design, forming an internal cavity to accommodate the card. An assembly port 2 is provided on one side of the cavity body 1 for installing the button 7. A first connecting rod 27 and a second connecting rod 28 are fixedly installed externally on the cavity body 1, arranged parallel to each other with a suitable distance between them. A flexible card strap 29 is fixedly connected between the first connecting rod 27 and the second connecting rod 28. The card strap 29 is made of a material with certain elasticity and wear resistance and is arranged in a ring shape.

[0075] Cartridge 29 is designed with dual functions:

[0076] Firstly, when a user removes a card from the cavity body 1 but needs to temporarily store it, the card can be inserted into the gap between the card strap 29 and the cavity body 1. Because the card strap 29 has a certain elastic tension, it can generate appropriate clamping force on the inserted card, preventing it from accidentally falling out. This design is particularly suitable for scenarios where the same card needs to be used frequently, such as repeatedly swiping a card in a shopping mall or repeatedly showing identification during security checks. Users do not need to completely put the card back into the cavity body 1 each time, improving efficiency and avoiding the risk of card loss.

[0077] Secondly, the card strap 29 can be used as a carrying device for the card holder. Users can attach the card strap 29 to their belt, which ensures the stability of the card holder and facilitates quick access to cards during outdoor activities or commuting.

[0078] When a card needs to be retrieved, the user presses button 7 on the main body 1. The push part 8 of button 7 acts on the abutting section 6 of the card pusher 4 via the inclined surface 9, pushing the entire card pusher 4 to move outward from the main body 1. The card tray section 5 of the card pusher 4 adopts a stepped bracket 31 design, which can push out the cards in the main body 1 in layers. The retrieved card can be temporarily inserted into the card tape 29, and then pushed back into the main body 1 after use.

[0079] In this embodiment, the plastic part 3 is provided with second screw through holes 34 on both the left and right sides. The second screw through holes 34 facilitate the fixed connection between the plastic part 3 and the cavity body 1 and the connecting rod (27, 28), improve the structural stability, and reduce the assembly difficulty.

[0080] Example 9

[0081] In this embodiment, the surface of button 7 is provided with an anti-slip texture 30, which significantly improves the pressing feel by optimizing the surface structure of button 7. When the user operates the card holder, the contact surface between the finger and button 7 generates moderate frictional resistance due to the presence of the anti-slip texture 30. This resistance not only prevents slippage during pressing but also provides tactile feedback through the micro-undulations of the texture. The anti-slip texture 30 adopts a uniformly distributed array of geometric patterns, and its height and spacing are ergonomically optimized to ensure anti-slip performance without causing a rough feel.

[0082] During card ejection, the user's thumb naturally applies force to the surface of button 7. The anti-slip texture 30 increases the roughness of the contact surface, providing a stable point of force application when the user presses vertically. This design is particularly suitable for humid environments or when hands are wet, fundamentally solving the problem of force deviation that easily occurs with traditional smooth buttons 7. The texture arrangement is at a specific angle to the direction of pressing force, creating an optimal mechanical match between the direction of friction and the direction of pushing force, reducing operator fatigue while ensuring precise transmission of the card-pushing action.

[0083] Example 10:

[0084] In this embodiment, the card holder's cavity body 1 adopts a hollow design, with a plastic component 3 fixedly installed inside. A card-pushing component 4 is movably installed on the plastic component 3. The card-pushing component 4 includes a card tray section 5 and an abutment section 6. The card tray section 5 is provided with multiple brackets 31, which are arranged in a stepped manner. The height of each bracket 31 is approximately equal to the thickness of a standard card, allowing the cards to be neatly placed on the bracket 31. When the user presses the button 7, the push part 8 of the button 7 contacts the abutment section 6 through the inclined surface 9, pushing the abutment section 6 to move, thereby driving the card tray section 5 to move. The movement of the card tray section 5 causes the cards on the brackets 31 to be gradually pushed out of the cavity body 1. Because the brackets 31 are arranged in a stepped manner, the pushed cards are also arranged in a stepped manner, making it easy for the user to quickly identify and retrieve the required cards.

[0085] The rigid structure of the cavity body 1 effectively protects the internal cards, preventing deformation or damage caused by external pressure. The design of the card pusher 4 ensures a smooth and orderly card ejection process, avoiding the problem of messy card stacking in traditional card holders. The stepped bracket 31 not only optimizes the card arrangement but also improves card retrieval efficiency, making it particularly suitable for scenarios requiring quick access to multiple cards.

[0086] Example 11:

[0087] In this embodiment, the cavity body 1 is manufactured using a one-piece extrusion profile molding process, resulting in high structural strength and effectively protecting the internal cards from deformation caused by external pressure. A plastic component 3 is fixedly installed inside the cavity body 1. The plastic component 3 is securely connected to the cavity body 1 via clips or screws, ensuring its stability during card holder use and preventing loosening or detachment due to frequent operation. When the plastic component 3 is fixed using clips, the clip structure is designed for elastic locking, allowing the plastic component 3 to fit tightly against the inner wall of the cavity body 1, while also facilitating assembly and maintenance. If screws are used for fixing, the tightening force of the screws is evenly distributed, preventing the plastic component 3 from shifting under stress.

[0088] Example 12:

[0089] In this embodiment, the beveled surface 9 has a contact angle of 15°-45°. When the user presses the button 7, the beveled surface 9 of the push part 8 of the button 7 contacts the abutting section 6 of the push-card component 4. This angle design causes the pushing force applied by the beveled surface 9 to the abutting section 6 to be divided into two components: a positive pressure perpendicular to the surface of the abutting section 6, and a tangential pushing force parallel to the surface of the abutting section 6. The positive pressure ensures that the abutting section 6 receives sufficient pushing force to drive the card tray section 5 to move, while the tangential pushing force assists the abutting section 6 to slide smoothly through friction.

[0090] During operation, the angle of the inclined plane 9 optimizes the efficiency of force transmission. A smaller angle may result in insufficient positive pressure, causing the push-card component 4 to move poorly; a larger angle will result in excessive tangential thrust, increasing the resistance to the operation of the button 7.
