Description

Technical Field

[0001] This utility model relates to the field of charger technology, specifically to a card swiping component. Background Technology

[0002] Card-swiping components are widely used in chargers and charging stations, bringing convenience to users who need charging. The structure that enables the card-swiping effect in a card-swiping component is the card-swiping plate, which houses electrical components and coils. The larger the coil area, the more sensitive the card-swiping component. Circuitry is etched on the card-swiping plate corresponding to the coil. To obtain the maximum coil area, the coil and circuitry need to be designed at the edge of the card-swiping plate. In existing technologies, most traditional card-swiping components use screw mounting or clip-on mounting. With screws or clips positioned at the edge of the card-swiping plate, grooves or through holes need to be created at the edge, and the coil and circuitry must avoid these areas, resulting in inefficient use of the card-swiping plate's area. Furthermore, placing screws or clips at the edge of the card-swiping plate brings them close to the edge of the outer casing with its raised curved surface, causing insufficient height and strength, and also complicating the injection molding process of the casing. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a card swiping component that can effectively utilize the card swiping area, improve card swiping sensitivity, simplify the shell manufacturing process, and improve product reliability.

[0034] The card reader assembly achieves the card-swiping effect through the card reader plate 2, which is itself a circuit board containing electrical components 22 and a coil. When alternating current is applied to the coil, it generates an alternating magnetic field. When a card approaches the card reader plate 2, the coil inside induces this alternating magnetic field, generating an induced electromotive force and producing a current. This achieves card reading through the principle of electromagnetic induction. According to Ampere's circuital law, the larger the area of ​​the coil, the greater the magnetic induction intensity, and the more sensitive the card reader assembly becomes. Circuitry is etched on the card reader plate 2 at positions corresponding to the coil. To obtain the maximum coil area, the coil and circuitry need to be designed at the edge of the card reader plate 2.

[0035] Traditional card reader assemblies mostly use screws 18 or hooks 12 to fix them to the edge of the card reader plate 2. To cooperate with the screws 18 or hooks 12, the edge of the card reader plate 2 needs to be provided with grooves or through holes to achieve a stable connection. The wiring on the card reader plate 2 must avoid these areas, resulting in the coil area on the card reader plate 2 being smaller than the maximum usable area, thus the area of ​​the card reader plate 2 is not effectively utilized. At the same time, because the card reader plate 2 needs to maintain a certain area, when the screws 18 or hooks 12 are installed on the edge of the card reader plate 2, the screws 18 or hooks 12 are too close to the edge of the outer shell 1 with its raised curved surface, resulting in insufficient connection height and the formation of a low-position connection. During the injection molding of the outer casing 1, the low-level connectors, such as the studs 17 and hooks 12 connected to the screws 18, are relatively small and complex, which can lead to difficulties in plastic filling. This complicates the injection molding process and results in insufficient strength of the molded product. Reducing the area of ​​the card reader 2 would decrease the sensitivity of the card reader assembly and affect its reliability. Therefore, it is necessary to relocate the connectors such as the screws 18 and hooks 12 to the portion of the card reader 2 located inside the coil. In this case, the studs 17 and hooks 12 are positioned on the flat plate 11 at the top of the curved panel 14, which is a greater distance from the card reader 2, providing sufficient height and strength and improving product reliability.

[0036] Reference Figure 1 The card-swiping assembly of this embodiment includes a card-swiping plate 2 and a housing 1. The card-swiping plate 2 is installed inside the housing 1 to achieve the card-swiping effect. The housing 1 is used to position and fix the card-swiping plate 2, and is connected to other external housings or structures via connectors to form a card-swiping charging station or card-swiping charger. The housing 1 includes a curved panel 14 and a flat panel 11, wherein the flat panel 11 is connected to the top of the curved panel 14, that is, the distance between the flat panel 11 and the card-swiping plate 2 decreases from the edge of the flat panel 11 to the edge of the curved panel 14. In other words, the height of the connector on the curved panel 14 is smaller than that of the connector on the flat panel 11.

[0037] Reference Figure 2 The card reader 2 is equipped with a coil and an electrical component 22. The coil and the corresponding wiring on the card reader 2 are not shown. The coil is electrically connected to both the card reader 2 and the electrical component 22, and the electrical component 22 is also electrically connected to the card reader 2. The coil is positioned near the edge of the card reader 2 surface to maximize the use of the card reader 2's area, ensuring the area enclosed by the coil is large enough and the resulting magnetic field has a high magnetic induction intensity, making the card reader assembly more sensitive. To effectively position and fix the card reader 2, at least two through slots are provided on the card reader 2, located inside the coil to avoid affecting the coil and wiring.

[0038] In some embodiments, the card reader 2 is installed by means of a snap-fit ​​hook 12. (Refer to...) Figure 1 , Figure 2 The card reader 11 uses hooks 12 as connectors. At least two hooks 12 are provided on the inner side of the flat plate 11; typically, two hooks 12 are chosen depending on the actual situation. Since the hooks 12 are positioned on the flat plate 11 and have a certain height, they are easier to fill completely and achieve better strength during injection molding of the outer casing 1. The through grooves that mate with the hooks 12 are slots 21. The number of slots 21 is the same as the number of hooks 12, also two, and the positions of the hooks 12 and slots 21 correspond one-to-one. One hook 12 and one slot 21 form a connection structure. The two sets of connection structures are at different distances from the edges of the card reader 2 to achieve a foolproof function, preventing incorrect installation such as inverted installation. Depending on the actual situation, one set of connection structures can be closer to the edge and the other set further away, or one set can be offset to one side and the other set offset to the other side. The card reader 2 is installed inside the housing 1 by engaging with the card slot 21 via hooks 12. When engaged, the lower end face of the hook-shaped part of the hook 12 contacts the outer side of the card reader 2. Depending on the actual situation, the hook-shaped parts of the two hooks 12 can be oriented oppositely or in the same direction. When the hook-shaped parts are oriented oppositely, their direction can also be outward or inward. At the same time, the two hooks 12 can make tight contact with the inner side of the card slot 21 to ensure the stability and reliability of the card reader 2 installation.

[0039] In some embodiments, refer to Figure 1 , Figure 2 The housing 1 also includes at least one positioning platform 13. The at least one positioning platform 13 protrudes from the flat plate 11 and / or curved plate 14 and contacts one side of the card reader 2. The number of positioning platforms 13 can be one, two, or more, and they are located on one side surface of the card reader 2, or at one or more corners, to better limit the positioning of the card reader 2 and provide height support, ensuring stable installation of the card reader 2 and maintaining a certain distance from the flat plate 11 without wobbling. Depending on the actual situation, the number of positioning platforms 13 is usually four, as shown in the reference. Figure 3 The positioning platform 13 includes a contact portion 131 and a limiting portion 132. The contact portion 131 is located on the side of the limiting portion 132 near the card reader 2. The height of the contact portion 131 is less than the height of the limiting portion 132, forming a stepped structure. When the positioning platform 13 is located at the four corners of the card reader 2, the contact portion 131 actually forms a protruding structure with a missing corner with the limiting portion 132. The top surfaces of the four contact portions 131 are located on the same plane, and the plane on which the top of the contact portion 131 is located is parallel to the flat plate 11, so that each contact portion 131 can make a tight fit with one side surface of the card reader 2 without problems such as protrusion or incomplete contact, thus enhancing the stability and reliability of the card reader 2 installation.

[0040] Reference Figure 2 , Figure 4 The included angle between the two sides of one side surface of the card reader 2 contacts the contact portion 131 and abuts against the limiting portion 132. That is, when the card reader 2 is installed on the positioning platform 13, both edges forming one corner can tightly contact the limiting portion 132, thus limiting the card reader 2. The vertical distance between the plane of the top of the contact portion 131 and the plane of the hook-shaped end face of the hook 12 is the same as the thickness of the card reader 2. That is, when the card reader 2 is installed via the hook 12, both its sides contact the contact portion 131 and the end face of the hook-shaped portion of the hook 12 respectively, positioning the card reader 2 in a fixed position. This prevents the card reader 2 from changing position due to bumps or movement, thus improving the stability and reliability of the card reader assembly.

[0041] In some embodiments, the positioning stage 13 can be a solid protrusion or a hollow cylindrical structure. When the positioning stage 13 is set as a hollow cylindrical structure, material usage can be further reduced, saving costs. (Refer to...) Figure 4 , Figure 5 The limiting part 132 is C-shaped with its opening facing the card reader 2. Both ends of the opening of each limiting part 132 extend to form a contact part 131. That is, the opening and the contact part 131 are actually located on the same side, and the contact part 131 is divided into two parts that connect to the limiting part 132 respectively. Depending on the actual situation, when there are four positioning platforms 13, two positioning platforms 13 are located on the side of the flat plate 11 near the curved plate 14, and the other two positioning platforms 13 are located on the curved plate 14. The bottom height of the positioning platforms 13 located on the curved plate 14 is different from the bottom height of the positioning platforms 13 located on the flat plate 11. The four limiting parts 132 surround and limit the four corners of the card reader 2, and the top surface of the contact part 131 contacts the four corners of the card reader 2, so that the four corners of the card reader 2 are inserted into the notches formed by the positioning platforms 13, such as... Figure 2 As shown. The end face of the hook-shaped portion of the hook 12 and the top surface of the contact portion 131 form a limiting force on the card reader 2 in a plane perpendicular to the card reader 2. The side of the hook 12, together with the card slot 21 and the limiting portion 132, forms a limiting force on the card reader 2 in a plane parallel to the card reader 2. This multi-directional limiting of the card reader 2 makes its installation more stable, improving the stability and reliability of the card reader assembly.

[0042] In some embodiments, refer to Figure 4 , Figure 5A reinforcing rib 121 is provided at the base of the hook 12, and a clearance groove 122 is provided on the side of the hook 12 away from the reinforcing rib 121. Depending on the actual situation, the reinforcing rib 121 is usually provided on the hook 12 away from the direction in which the hook-shaped part faces. The inclination direction of the guide slope at the top of the hook-shaped part is opposite to the direction of the buckle bending during installation; for example, when the hook-shaped part is set facing outwards, refer to... Figure 2 During installation, the card slot 21 of the card reader 2 will press the hook-shaped part perpendicular to the guide slope, causing the hook 12 to bend towards the side opposite to the guide slope. This continues until the height of the outer surface of the card reader 2 is lower than the height of the hook-shaped part's end face. When the pressure on the guide slope ceases, the hook 12 rebounds, achieving a snap-fit ​​connection with the card reader 2. Simultaneously, when an external impact occurs, the movement of the card reader 2 will press the hook 12 in the opposite direction to the hook-shaped part's orientation. Therefore, a reinforcing rib 121 needs to be provided on the side of the hook 12 away from the hook-shaped part's orientation.

[0043] Reference Figure 4 Depending on the actual situation, the clearance groove 122 can be a non-through injection groove or a through hole. When it is necessary to apply a film or cover tempered glass to the outer surface of the flat plate 11, since the hook 12 is set on the flat plate 11, its back will be covered by the film or tempered glass. Therefore, the clearance groove 122 can be designed as a through hole, so that the hook 12 does not need to use a mold with a slanted top structure when injection molding, which effectively simplifies the production process of the shell 1 and reduces costs.

[0044] In some embodiments, refer to Figure 6 , Figure 7 The card reader 2 is installed using screws 18. Studs 17 are used as connectors; at least two studs 17 are provided on the inner side of the flat plate 11. The studs 17 and screws 18 cooperate to limit the position of the card reader 2. The top surfaces of at least two studs 17 are on the same horizontal plane, parallel to the flat plate 11. Because the studs 17 are located on the flat plate 11 and have a certain height, better strength is easily obtained during injection molding. The through slots that mate with the studs 17 are screw holes 23. The number of screw holes 23 is the same as the number of studs 17, and their positions correspond one-to-one. One screw hole 23, one stud 17, and one screw 18 form a connection structure. The diameter of the screw head 18 is larger than the diameter of the screw hole 23, allowing the card reader 2 to be fixed. At least two sets of connection structures are at different distances from the two side edges of the card reader 2 to achieve a foolproof function, avoiding incorrect installation problems such as inverted installation. When the card reader 2 needs to be installed, align the screw hole 23 of the card reader 2 with the stud 17 and screw in the screw 18 so that the card reader 2 is stably positioned by the screw 18 and the stud 17, thereby improving the stability and reliability of the card reader assembly.

[0045] In some embodiments, refer to Figure 1 The flat panel 11 is equipped with a light assembly 15, and the curved panel 14 has multiple fixing components 16 along its edge. Depending on the specific application, the fixing components 16 can be studs 17, which, in conjunction with screws 18, are used to secure the card reader to other structures. The light assembly 15 displays the card swiping result or charging status, enhancing the user experience.

[0046] This application provides a card-swiping assembly, which includes a card-swiping plate and a housing. A coil is arranged on the card-swiping plate. The housing includes a curved panel and a flat panel on top of the curved panel. At least two hooks are provided on the flat panel. The card-swiping plate has slots within the coil, with each slot corresponding to a hook. The card-swiping plate is installed inside the housing by engaging the hooks with the corresponding slots. By placing the slots and hooks inside the coil of the card-swiping plate, the connection between the card-swiping plate and the housing does not occupy the edge of the card-swiping plate. The coil can fully utilize the area of ​​the card-swiping plate. Simultaneously, the hooks, located on the flat panel on top of the curved panel, have sufficient height and strength, facilitating the fabrication of the housing mold. This achieves the effects of improved card-swiping sensitivity, simplified housing manufacturing process, and enhanced product reliability.
