[0023] Reference Figure 1 This utility model proposes a card pusher for a card holder, which is applied to a card storage box. It includes a drive component 100 and a buffer component 200 connected to one side of the drive component 100. The drive component 100 includes a base 110 and a push rod 120 connected to the base 110. The buffer component 200 includes a buffer block 220, which is made of silicone and has a plurality of friction protrusions 221 evenly arranged on it.
[0024] In a specific embodiment, the base 110 is made of high-strength plastic, possessing excellent wear resistance and stability. The shape of the base 110 is adapted to the internal structure of the card holder and is installed at the bottom of the holder using screws or other fixing methods. The push rod 120 has sufficient strength and rigidity to withstand the pressure when pushing the card. One end of the push rod 120 is connected to the base 110 via a pivot, allowing for rotation at a certain angle; the other end is a card-pushing end, used to abut and push the card. When the user presses the card-pushing button on the card holder, the push rod 120 rotates around the hinge, and the card-pushing end of the push rod 120 pushes the card out of the holder. A buffer block 220 is installed on one side of the push rod 120 and moves synchronously with it. The buffer block 220 is made of rubber, possessing good elasticity and cushioning performance. The size and shape of the buffer block 220 are designed according to the size of the card and the internal space of the holder to ensure full contact with the side of the card. Friction ridges 221 are evenly distributed on the surface of the buffer block 220 and are made of silicone. The friction ridge 221 is a long, thin strip.
[0025] In some embodiments, the height of the friction ridge 221 is 1-2 mm, the width is 0.5-1 mm, and the spacing between two adjacent friction ridges 221 is approximately 2-3 mm. When the push rod 120 pushes the card out, the friction ridge 221 on the buffer block 220 contacts the side of the card, thereby increasing the friction force and slowing down the speed at which the card extends.
[0026] In other embodiments, the buffer block 220 is made of a multi-layer composite material, consisting of an outer rubber layer and an inner sponge layer. The rubber layer has good wear resistance and elasticity, capable of withstanding the friction between the card and the buffer block 220; the sponge layer has good cushioning performance, further absorbing the impact force when the card extends. Wavy friction ridges 221 are laser-engraved on the surface of the rubber layer of the buffer block 220. The wavy friction ridges 221 have a high surface roughness, increasing the contact area and friction with the side of the card, thereby more effectively slowing down the card's extension speed.
[0027] Understandably, by setting up the buffer component 200, during the card extension process, the friction protrusions 221 on the buffer block 220 contact the side of the card, increasing the resistance encountered by the card during extension, effectively slowing down the card extension speed, preventing the card from falling due to inertia, and improving the safety of card use. Furthermore, the friction protrusions 221 are evenly distributed on the surface of the buffer block 220, making the friction force on the card more evenly distributed during extension, reducing card jamming and offset, and improving the smoothness and stability of card ejection.
[0028] Reference Figure 1Specifically, the buffer assembly 200 further includes a mounting plate 210. The mounting plate 210 is made of plastic and is fixedly connected to one side of the base 110 by screws, maintaining a perpendicular connection with the base 110. The buffer block 220 is also made of rubber and is firmly attached to the mounting plate 210 by adhesive. Thus, when the push rod 120 of the drive assembly 100 pushes the card, the buffer block 220, along with the mounting plate 210, can provide cushioning for the card. The mounting plate 210 ensures a more stable and standardized installation of the buffer block 220, guaranteeing accurate contact between the buffer block 220 and the card, thereby more effectively providing cushioning and improving the stability of the card ejection.
[0029] In some embodiments, the buffer components 200 are configured in two sets, symmetrically located at both ends of the base 110. Each set of buffer components 200 includes a mounting plate 210 and a buffer block 220. The mounting plate 210 is vertically connected to both ends of the base 110, and the buffer block 220 is mounted on the mounting plate 210. When the push rod 120 pushes the card, the buffer components 200 at both ends simultaneously apply resistance to the card, making the force on the card more uniform during extension, further enhancing the buffering effect, and better preventing the card from falling or shifting due to uneven force, thus improving the reliability and stability of card extension.
[0030] Reference Figure 1 The mounting plate 210 has a slide rail 211 on its surface. The slide rail 211 is made of metal and is installed on the mounting plate 210 by welding or screws. The bottom of the buffer block 220 has a groove that matches the slide rail 211, and the buffer block 220 is inserted into the slide rail 211 through the groove. When the card is pushed out by the push rod 120, the buffer block 220 can move a preset distance along the slide rail 211 as the card extends. The slide rail 211 allows the buffer block 220 to dynamically adjust according to the extension of the card. In the initial stage of card extension, the buffer block 220 can be close to the starting position of the card to provide initial cushioning; as the card extends, the buffer block 220 moves along the slide rail 211 to continuously provide cushioning, making the cushioning effect more flexible and effective.
[0031] It should be noted that the preset distance has been precisely calculated and experimentally verified, and does not exceed 1 / 3 of the card length. For example, for a card with a length of 85mm, the preset distance is set to no more than 28mm. In this way, during the card extension process, the buffer block 220 can provide cushioning within an appropriate range, neither losing its cushioning effect prematurely nor affecting the normal extension of the card due to excessive movement. It can ensure the cushioning effect while avoiding excessive movement of the buffer block 220 that could interfere with the card extension, ensuring that the card can be extended smoothly and stably.
[0032] In some embodiments, the slide rail 211 is provided with two or more buffer blocks 220. For example, two buffer blocks 220 are provided on one slide rail 211, and a certain distance is maintained between the two buffer blocks 220. When the card is extended, the two buffer blocks 220 can contact the card simultaneously, providing a double buffering effect.
[0033] It should be noted that one or both ends of the base 110 are provided with anti-detachment hooks 111. The anti-detachment hooks 111 are made of elastic plastic and are integrally molded with the push rod 120 through injection molding. The anti-detachment hooks 111 are hook-shaped and can be locked into the corresponding grooves inside the card box to prevent the base 110 from accidentally falling off during use.
[0034] Reference Figure 1 The push rod 120 has multiple steps 121 on one side, which are equidistantly and evenly arranged on the side wall of the push rod 120. The steps 121 are made of metal and are formed on the push rod 120 by machining. The multiple steps 121 allow the push rod 120 to make stepped contact with different cards when pushing the card, ensuring that one step 121 corresponds to one card, thereby reducing the risk of the card being scratched. At the same time, the step structure also helps to improve the strength and stability of the push rod 120.
[0035] It should be noted that the end of the push rod 120 and the multiple steps 121 are all provided with clearance arc edges 122. The clearance arc edges 122 are formed by a grinding process, and their curvature can prevent the push rod 120 from making sharp contact with the edge of the card when pushing the card, effectively preventing the card from being scratched and protecting the appearance quality of the card. This ensures that the push rod 120 will not scratch the card when it comes into contact with it.
[0036] Furthermore, the push rod 120 is connected to the base 110 via a pivot made of metal, which has good wear resistance and rotational flexibility.
[0037] Specifically, a drive torsion spring is fitted onto the rotating shaft. The drive torsion spring is made of high-quality spring steel and undergoes a special heat treatment process to give it good elasticity and fatigue resistance. Both ends of the drive torsion spring are fixedly connected to the push rod 120 and the base 110, respectively. Specifically, the push rod 120 is provided with a slot specifically for fixing one end of the drive torsion spring, the width of which matches the wire diameter of the drive torsion spring; the base 110 is provided with a protruding structure, and the other end of the drive torsion spring is fixed by wrapping it around the protruding structure.
[0038] When the card is not ejected, the drive torsion spring is in its initial state, applying a preload to the push rod 120, keeping it in a specific initial position. When it is necessary to eject the card, an external drive mechanism applies a force to the push rod 120 in the opposite direction to the preload of the drive torsion spring, overcoming the resistance of the drive torsion spring and causing the push rod 120 to rotate around its axis, thereby pushing the card out. When the external drive force is removed, the drive torsion spring, under its own elastic force, drives the push rod 120 to rotate in the opposite direction, returning the push rod 120 to its initial position, preparing it for the next card ejection operation.
[0039] Alternatively, the push rod 120 may be initially tilted. Under the action of the card push and the external limiting mechanism, the push rod 120 overcomes the resistance of the drive torsion spring and becomes flush with the base 110. By releasing the action of the external limiting mechanism, the push rod 120 rotates around the pivot under the elastic force of the drive torsion spring, thereby pushing the card out.
[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.
