Description

Technical Field

[0001] This utility model relates to the field of card storage production and processing technology, specifically a device for card position detection and pre-pressing. Background Technology

[0002] In fields such as finance, telecommunications, data storage, and card manufacturing, storage, management, and processing devices for card-based devices (such as SIM cards, SD cards, and IC cards) are widely used. Traditional card storage devices primarily employ mechanical card slot structures, using physical restraints to secure the cards. After a card is inserted into the slot, it relies solely on its own weight to remain in place. The device vibrates during operation, and if it is not placed horizontally, the card risks slipping out of the slot. Secondly, the status of the card slot in the card device needs to be detected (whether there is a card in the slot and its position within the slot).

[0003] To address these issues, traditional methods typically involve adding an elastic (spring or sheet) card-pressing device within the card slot to hold the card in place. However, this method is structurally complex and costly. Furthermore, detecting the card's position in the slot usually utilizes photoelectric sensors, which are prone to malfunction when contaminated by dust, oil, or other contaminants, and the overall cost is also high. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a device for card position detection and pre-pressing. By setting a tactile switch in the card slot, the problem of pressing the card in the card slot is solved, as well as the problem of detecting the state of the card in the card slot is solved.

[0005] This utility model provides a device for card position detection and pre-pressing, characterized in that it includes a back plate, a slotted plate symmetrically fixedly arranged on one side of the back plate, card slots uniformly arranged on the inner side of the slotted plate, the card slots on different slotted plates being symmetrically arranged, a switch slot arranged on the outer side of at least one slotted plate, a tactile switch uniformly arranged in the switch slot, a sealing plate fixedly arranged on the outer side of the slotted plate and on the outer side of the switch slot, the tactile switch being fixedly connected to the sealing plate, an elastic pressure rod arranged on the inner side of the tactile switch, the elastic pressure rod extending to the inner side of the card slot, each layer of card slots corresponding to one layer of tactile switches, and the side of the card slot away from the back plate extending to the outer side of the slotted plate.

[0006] In a preferred embodiment, each layer has two tactile switches, with the elastic levers of the two tactile switches corresponding to the inner sides of the front and rear ends of the slot, respectively.

[0007] In a preferred embodiment, each of the slot plates has two parallel switch slots on its rear side, and two tactile switches on the same layer are located in the two switch slots respectively.

[0019] 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.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown

[0021] A device for card position detection and pre-pressing, characterized in that it includes a back plate 1, a slotted plate 2 symmetrically fixed on one side of the back plate 1, card slots 3 uniformly arranged on the inner side of the slotted plate 2, the card slots 3 located on different slotted plates 2 being symmetrically arranged, a switch slot 4 arranged on the outer side of at least one slotted plate 2, a tactile switch 5 uniformly arranged in the switch slot 4, a sealing plate 6 fixedly arranged on the outer side of the slotted plate 2 and on the outer side of the switch slot 4, the tactile switch 5 being fixedly connected to the sealing plate 6, an elastic pressure rod 7 arranged on the inner side of the tactile switch 5, the elastic pressure rod 7 extending to the inner side of the card slot 3, each layer of card slot 3 corresponding to one layer of tactile switch 5, the side of the card slot 3 away from the back plate 1 extending to the outer side of the slotted plate 2. The card slots 3 are arranged parallel to each other. When a card is inserted into the card slot, a tactile switch 5 is arranged on the side (one side or both sides) of the card slot 3, and pressure is applied to the side of the card by the elastic pressure rod 7 of the tactile switch 5, so that the state of the card in the card slot 3 of the device is stabilized. A tactile switch 5 is installed on the side of the card slot 3 of the device. A card in the card slot 3 will trigger the corresponding tactile switch 5. The on / off characteristics of the tactile switch 5 can be used to determine the state of the card slot 3. The position of the tactile switch 5 indicates the location of the card in the card slot 3; that is, when a certain layer of tactile switches 5 is on, it means there is a card in the card slot 3 corresponding to that layer of tactile switches 5; when a certain layer of tactile switches 5 is off, it means there is no card in the card slot 3 corresponding to that layer of tactile switches 5. The card will not fall out of the card slot 3 due to device vibration or improper placement.

[0022] Two tactile switches 5 are provided on each layer, and the elastic pressure rods 7 of the two tactile switches 5 correspond to the inner sides of the front and rear ends of the card slot 3, respectively. The tactile switches 5 apply more even pressure to the sides of the card, making the card less prone to damage.

[0023] Each slot 2 has two parallel switch slots 4 on its rear side, and two tactile switches 5 on the same layer are located in the two switch slots 4 respectively. This makes it easier to install and fix the tactile switches 5.

[0024] The sealing plate 6 is fixedly connected to the slot plate 2 by the clip 10. This facilitates the installation and removal of the sealing plate 6, thereby aiding in the maintenance of the tactile switch 5.

[0025] Fixed connecting plates 8 are symmetrically arranged on both outer sides of the back plate 1, and fixed connecting plates 8 are provided with fixed connecting holes 9. This facilitates the installation of this utility model on the equipment.

[0026] A base plate 11 is provided between the bottom of the channel plates 2 to enhance the strength and stability of the entire structure.

[0027] A pressure roller 12 is rotatably mounted on one end of the elastic pressure rod 7 located in the card slot 3. The pressure roller 12 serves as a guide, facilitating the insertion and removal of the card from the card slot 3.

[0028] The tactile switch 5 in this invention is a common electronic component, mainly used to momentarily connect or disconnect a circuit by manual pressing. Its characteristics include light operating force, sensitive triggering, and typically, it connects (or disconnects) when pressed and automatically resets when released. This invention can use commercially available models. The tactile switch has a long lifespan and low cost. Its internal structure is fully sealed, unaffected by dust or oil, and its purely mechanical nature ensures stable performance. This invention integrates card position detection and pre-pressing functions into a single device, simplifying the design and improving system reliability and efficiency.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
