For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0027] like Figures 1 to 3 As shown, a thin and light smart card reader device effectively reduces the thickness, is thinner and lighter as a whole, and is convenient for use in devices with smaller spaces. The card reader device of this embodiment includes a card holder body 1 and a control board 2, and a smart card can be inserted into the card holder body 1 and contact the control board 2 so as to read the data information in the smart card for identification. Specifically, the card holder body 1 of this embodiment includes an upper cover plate 3 and a lower cover plate 4, wherein the upper cover plate 3 and the lower cover plate 4 are both square cover structures with three side walls, so that the upper cover plate 3 and the lower cover plate 4 are buckled and connected with each other to form a card holder body 1 with an internal space, and the card holder body 1 forms an insertion port 11 at one end where the upper cover plate 3 and the lower cover plate 4 are not provided with side walls. In this embodiment, the control board 2 for identifying the smart card is arranged in the card holder body 1 formed by buckling the upper cover plate 3 and the lower cover plate 4, so that the control board 2 can be combined with the internal space of the card holder body 1 to form a card slot space 12 connected with the plug interface 11, so that the smart card can be directly inserted into the card slot space 12 from the plug interface 11 to achieve connection with the control board 2, without additionally arranging a card slot seat for the control board 2 to be plugged in, which effectively reduces the overall thickness of the card reader device of this embodiment, making the card reader device thinner and lighter, thereby facilitating use in devices with narrow space.

[0028] like Figure 1 and Figure 2 As shown, the projection area of ​​the upper cover plate 3 of this embodiment is smaller than the projection area of ​​the lower cover plate 4. When the upper cover plate 3 and the lower cover plate 4 are buckled and snapped, the upper cover plate 3 is integrally embedded in the lower cover plate 4, and the three side walls of the upper cover plate 3 and the three side walls of the lower cover plate 4 are tightly attached to realize the buckle, and the upper cover plate 3 and the lower cover plate 4 are combined to form an internal space of the side wall height. Specifically, the surfaces of the three side walls of the upper cover plate 3 of this embodiment are all provided with first snap-in blocks 31, and the surfaces of the three side walls of the lower cover plate 4 are all provided with first snap-in interfaces 41, wherein the positions of the first snap-in blocks 31 and the first snap-in interfaces 41 correspond, so that when the upper cover plate 3 is buckled into the lower cover plate 4, the first snap-in blocks 31 can be snapped into the first snap-in interfaces 41, thereby realizing a stable connection between the upper cover plate 3 and the lower cover plate 4.

[0029] like Figure 1 and Figure 2As shown, in this embodiment, the card slot space 12 formed by combining the control board 2 and the internal space of the card seat body 1 is provided to replace the card slot seat to reduce the overall thickness of the card reader device. In order to facilitate the smart card to be accurately plugged into the card slot space 12 to achieve connection with the control board 2, in this embodiment, a protruding plug-in protrusion 42 is provided on the surface of the lower cover plate 4 located in the card slot space 12, wherein the plug-in protrusion 42 extends from one end of the lower cover plate 4 close to the plug interface 11 to extend into the card slot space 12, and is combined with the inner surface of the lower cover plate 4 to form a mounting groove 43. The control board 2 can be installed in the mounting groove 43, so that when the smart card is inserted from the plug interface 11, the smart card can be accurately inserted into the card slot space 12 along the plug-in protrusion 42 and tightly connected with the contact position of the control board 2, thereby achieving accurate plugging of the smart card.

[0030] like Figure 2 and Figure 3 As shown, in order to stably install the control board 2 in the installation groove 43, in this embodiment, an elastic clip 44 bent into the slot space 12 is provided on the surface of the lower cover plate 4 located in the installation groove 43 area. After the control board 2 is installed in the installation groove 43, the elastic clip 44 can be clamped on the surface of the control board 2, so that the control board 2 can be clamped between the elastic clip 44 and the inner surface of the lower cover plate 4, thereby making the installation of the control board 2 more stable.

[0031] like Figure 2 and Figure 3 As shown, the surface of the control board 2 of this embodiment is provided with a plurality of metal springs 21 parallel to the plug-in direction. After the smart card is plugged into the card slot space 12, the metal sheet position on its surface can contact the metal spring 21 of the control board 2 of this embodiment to achieve the connection between the two. In order to achieve a stable contact connection between the smart card and the control board 2, the metal spring 21 is provided with a protrusion 211 bent toward the upper cover 3 in this embodiment, so that when the smart card is plugged into the card slot space 12 along the plug-in protrusion 42, the protrusion 211 of the metal spring 21 can be pushed up and abutted against the metal sheet position of the smart card, so that the contact between the metal spring 21 and the metal sheet is tighter and more stable, thereby achieving a stable contact connection between the smart card and the control board 2. In addition, the protrusion 211 of the metal spring 21 of this embodiment is an arc structure, so that when the smart card is plugged into the card slot space 12, it can move along the arc of the protrusion 211, which is convenient for the plug-in of the smart card.

[0032] In addition, in the present embodiment, the upper cover plate 3 and the protrusion 211 are provided with avoidance openings 32 at positions corresponding to the positions. When the metal spring 21 bounces up naturally, its protrusion 211 can be embedded in the avoidance opening 32. This can not only prevent the protrusion 211 from being pressed by the upper cover plate 3 for a long time to produce metal fatigue, thereby affecting the contact effect between the metal spring 21 and the smart card metal sheet, but also prevent the metal cover plate from being pushed up by the protrusion 211 of the metal spring 21 for a long time to cause protrusions on its surface. At the same time, it can further reduce the thickness of the present embodiment, making the card reading device of the present embodiment thinner and lighter.

[0033] like Figures 1 to 3 As shown, the control panel 2 of this embodiment is also provided with a switch spring. When the smart card is accurately inserted into the card slot space 12, the switch spring is pushed, and the control panel 2 is powered on for identification, which can avoid the control panel 2 being directly powered on during the smart card insertion process, resulting in card reading failure or damage to the smart card. Specifically, the switch spring of this embodiment is arranged at the end of the metal spring 21, so that the smart card can only contact the switch spring after it is completely and accurately inserted into the card slot space 12, thereby realizing the start-up card reading of the control panel 2. Among them, the switch spring of this embodiment includes a first spring 22 and a second spring 23 arranged in sequence along the smart card insertion direction, and the second spring 23 is located at the rear side of the first spring 22. After the smart card is accurately inserted into the card slot space 12, the front end of the smart card can push the first spring 22 to move and abut against the surface of the second spring 23, and then the control panel 2 starts to identify and read the smart card.

[0034] Furthermore, the first spring piece 22 of the present embodiment is also provided with an outer protrusion 221 protruding toward one side of the insertion port 11. When the smart card is inserted into the card slot space 12, the front end of the smart card can abut against the outer protrusion 221, thereby pushing the end of the first spring piece 22 to abut against the surface of the second spring piece 23, thereby facilitating the contact connection between the first spring piece 22 and the second spring piece 23.

[0035] like Figures 2 to 4 As shown, in order to improve the stability of the smart card after insertion and ensure accurate card reading of the control card, a lower pressing piece 34 inclined to the card slot space 12 is provided on the top of the upper cover 3 in this embodiment, and clamping protrusions 35 recessed into the card slot space 12 are provided on the side walls of the upper cover 3 located on both sides of the insertion interface 11, so that when the smart card is inserted from the insertion interface 11 into the card slot space 12, the lower pressing piece 34 on the end surface of the upper cover 3 can abut against the surface of the smart card, so that the metal sheet on the other side of the smart card can be in close contact with the metal spring sheet 21, thereby realizing a close connection between the control board 2 and the smart card. At the same time, the clamping protrusions 35 on both sides of the upper cover 3 can clamp and limit the two sides of the smart card, so that the smart card can be inserted into the card slot space 12 in an accurate centered position when inserted, thereby realizing an accurate contact connection between the control board 2 and the smart card.

[0036] like Figure 4 As shown, the side of the clamping protrusion 35 of this embodiment close to the insertion port 11 is an inclined surface, and the inclined surface gradually rises from the direction close to the insertion port 11 to the direction away from the insertion port 11, so that when the smart card is inserted into the card slot space 12, the edge of the smart card can be gradually inserted along the lower inclined surface of the clamping protrusion 35, which is convenient for the insertion of the smart card.

[0037] In addition, the side wall of the upper cover plate 3 of the present embodiment is further provided with a guide piece 36 bent into the card slot space 12. The guide piece 36 of the present embodiment is horizontally arranged at the middle height position of the card slot space 12. When the smart card is inserted, the guide piece 36 can be supported on the edge of the smart card. At the same time, under the action of the insertion protrusion 42, the smart card can be accurately inserted into the card slot space 12 and contact the metal spring piece 21 of the control board 2, thereby realizing the reading of the smart card. The side of the guide piece 36 of the present embodiment close to the insertion interface 11 is inclined toward the lower cover plate 4, so that the smart card can be inserted and moved along the inclined end of the guide piece 36 to the guide piece 36, which is convenient for the insertion of the smart card.

[0038] like Figure 2 and Figure 3 As shown, the control board 2 of this embodiment is firmly installed in the installation slot 43 by means of an elastic clip 44. In order to further improve the stability of the control board 2 after installation and prevent the control board 2 from moving during the smart card insertion process, this embodiment provides a plurality of positioning holes 24 on the end face of the control board 2, and provides positioning pieces 45 bent into the card slot space 12 at corresponding positions on the surface of the lower cover plate 4. When the control board 2 is installed in the installation slot 43, the positioning pieces 45 can be plugged into the positioning holes 24, thereby limiting the position of the control board 2, and preventing the control board 2 from moving during the smart card insertion process and affecting the subsequent card reading work.

[0039] In addition, if Figure 2 and Figure 3 As shown, a second clamping block 451 is further provided on the surface of any positioning piece 45 of the present embodiment, and a clamping piece 33 bent into the card slot space 12 is provided at a position on the surface of the upper cover plate 3 corresponding to the positioning piece 45, and a second card interface 331 is provided on the clamping piece 33, so that the upper cover plate 3 and the lower cover plate 4 can be clamped at the edge position through the first clamping blocks 31 and the first card interface 41 of the two side walls, and the middle end surface positions of the two can be connected through the second clamping block 451 and the second card interface 331 set at the end surface position, which can effectively improve the connection strength between the upper cover plate 3 and the lower cover plate 4, and at the same time, it can avoid the bulge on the surface of the upper cover plate 3 due to the insertion of the control card, thereby ensuring the lightness and thinness of the card reading device of the present embodiment.

[0040] To summarize, in this embodiment, the upper cover plate 3 and the lower cover plate 4 are snap-fitted to form a card holder body 1 with an internal space, so that after the control board 2 is installed, it can be combined with the internal space of the card holder body 1 to form a card slot space 12. Compared with the prior art, there is no need to additionally set up the card slot space 12, thereby effectively reducing the overall thickness of the card reader device, making it convenient to use in devices with a smaller internal space; and, in this embodiment, an upper cover plate 3 and a lower cover plate 4 with three side walls are set up, so that after the upper cover plate 3 and the lower cover plate 4 are connected, an insertion interface 11 connected to the card slot space 12 can be formed on one side end face of the card holder body 1, so that the smart card can be directly plugged into the card slot space 12 through the insertion interface 11, thereby simplifying the overall structure of the card reader device.

[0041] The embodiments described above are only preferred implementation modes of the present utility model and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the protection scope of the present utility model.
