Description

Technical Field

[0001] This invention relates to a card reader for electrically connecting a chip-equipped card to an electronic device, and in particular, a card reader that can hide or expose two types of USB connectors by means of rotation. Background Technology

[0002] There are many types of cards with embedded chips (hereinafter referred to as chip cards), such as debit cards, credit cards, health insurance cards, etc. The data stored in the chip needs to be connected to electronic devices (such as computers, mobile phones, etc.) to be read. Therefore, a card reader is needed as a connection medium between the chip card and the electronic device.

[0003] Current electronic devices are mainly equipped with USB (Universal Serial Bus) ports as interfaces for telecommunications connection to other electronic devices, and the specifications of the USB ports vary depending on when the electronic device was purchased; for example, it has evolved from the early USB 1.0, USB 1.1, USB 2.0, USB 3.0, etc. to the currently widely used Type-C.

[0004] Connecting a chip card to an electronic device involves inserting the chip card into the card reader's slot to make electrical contact with the internal terminals, and then plugging the card reader's USB connector into the electronic device's USB port. Well-known card readers only have one type of USB connector (e.g., Taiwan Patent M567909), so when encountering electronic devices with different connector specifications, it is necessary to purchase a card reader of the corresponding specification, which is inconvenient and wasteful of money. Summary of the Invention

[0005] The purpose of this invention is to provide a card reader equipped with two different types of USB connectors, and which can be conveniently hidden and stored when not in use.

[0006] The card reader provided by the present invention includes the following technical means: a body having an opening and a slot; a main circuit board disposed within the body, the main circuit board being electrically connected to a plurality of first conductive terminals and a plurality of second conductive terminals; a first USB connector module rotatably disposed within the body, comprising a first circuit board and a first USB connector electrically connected to the first circuit board, the first circuit board being provided with a plurality of first conductive metals; a first rotating member movably disposed within the body and fixedly connected to the first USB connector module; a second USB connector module rotatably disposed within the body, comprising a second circuit board and a second USB connector electrically connected to the second circuit board, the second circuit board being provided with a plurality of second conductive metals; and a second rotating member movably disposed within the body and fixedly connected to the second USB connector module; wherein, the first rotating member controls the first USB connector module to reciprocate, and when the first USB connector module rotates to expose the first USB connector to a predetermined position through the opening, the plurality of first conductive terminals and the plurality of first conductive metals make electrical contact; The second rotating component controls the reciprocating rotation of the second USB connector module. When the second USB connector module rotates and exposes the second USB connector to a predetermined position through the opening, the plurality of first conductive terminals make electrical contact with the plurality of second conductive metals. Furthermore, when a card is inserted into the slot, the chip on the card makes electrical contact with the plurality of second conductive terminals. Through this card reader structure, users can not only select which USB connector to expose based on the USB port specifications of their electronic device, but also conveniently hide both types of USB connectors within the reader when not in use, facilitating storage and portability.

[0007] In one embodiment of the present invention, the first USB connector module may further include a first fixing block connected to the first rotating member, which is formed as a block with one corner beveled to form a first bevel, for example, 45°; the second USB connector module further includes a second fixing block connected to the second rotating member, which is also formed as a block with one corner beveled to form a second bevel, for example, 45°; wherein, when the first USB connector or the second USB connector is fully exposed in the body, the first bevel of the first fixing block and the second bevel of the second fixing block abut against each other, so that the first USB connector and the second fixing block maintain a 90° angle between them, and the first fixing block and the second fixing block can push and rotate against each other. Accordingly, its use can be made more convenient.

[0008] Preferably, the present invention can arrange the opening and the slot on opposite sides of the body. Accordingly, the USB connector exposed on one side of the body can be inserted into the USB port of an electronic device, and the other side of the body can be used to insert a chip card.

[0009] Preferably, the present invention may provide a positioning part at the opening of the main body. When the plurality of first conductive terminals make electrical contact with the plurality of first conductive metals, the positioning part positions the first rotating member; when the plurality of first conductive terminals make electrical contact with the plurality of second conductive metals, the positioning part positions the second rotating member. Accordingly, the positioned first rotating member can prevent the first USB connector from wobbling, and the positioned second rotating member can prevent the second USB connector from wobbling, which is beneficial for plugging the first or second USB connector into the USB port of the electronic device.

[0010] In one embodiment of the present invention, the positioning portion may include an elastic portion formed on the body and a positioning block formed on the elastic portion; the first rotating member is provided with a first positioning recess, and when the plurality of first conductive terminals are in electrical contact with the plurality of first conductive metals, the elasticity of the elastic portion causes the first positioning recess and the positioning block to engage with each other to position the first USB connector module; and the second rotating member is provided with a second positioning recess, and when the plurality of first conductive terminals are in electrical contact with the plurality of second conductive metals, the elasticity of the elastic portion causes the second positioning recess and the positioning block to engage with each other to position the second USB connector module. With this structure, the first USB connector or the second USB connector can be automatically positioned by elasticity after rotating out of the body to a predetermined position, and can be rotated back into the body by manually overcoming the elasticity to release the positioning.

[0011] In another embodiment of the present invention, the positioning part may include a latch and a push button slidably disposed on the body, and the latch and the push button are connected to each other; the first rotating member is provided with a first positioning recess, and when the plurality of first conductive terminals are in electrical contact with the plurality of first conductive metals, the first positioning recess corresponds to the latch, and by pushing the push button, the latch is inserted into the first positioning recess to position the first USB connector module, and by pushing the push button in the opposite direction, the latch is disengaged from the first positioning recess to release the positioning; and the second rotating member is provided with a second positioning recess, and when the plurality of first conductive terminals are in electrical contact with the plurality of second conductive metals, the second positioning recess corresponds to the latch, and by pushing the push button, the latch is inserted into the second positioning recess to position the first USB connector module, and by pushing the push button in the opposite direction, the latch is disengaged from the second positioning recess to release the positioning. With the above structure, the first USB connector or the second USB connector can be manually positioned after being rotated out of the body to a predetermined position, and after being manually released from positioning, the first USB connector or the second USB connector can be rotated back into the body.

[0012] In one embodiment of the present invention, a circular through hole is provided in the main body, and a circular seat is provided at the center of the through hole. An annular groove is formed between the inner circumference of the through hole and the outer circumference of the seat. The first rotating member is formed with a first USB connector mounting base, a first arc plate, and a first handle. The first USB connector mounting base is used to mount the first USB connector. When the first rotating member is provided in the main body, the first arc plate covers a portion of the annular groove, and the first handle protrudes from the annular groove. The first arc plate can slide along the annular groove. The second rotating member is formed with a second USB connector mounting base, a second arc plate, and a second handle. The second USB connector mounting base is used to mount the second USB connector. When the second rotating member is provided in the main body, the second arc plate covers another portion of the annular groove, and the second handle protrudes from the annular groove. The second arc plate and the first arc plate are offset from each other in the height direction and can slide along the annular groove. With this structure, the user can easily turn the first handle to rotate the first USB connector in and out of the main body, or turn the second handle to rotate the second USB connector in and out of the main body.

[0013] Preferably, the present invention can form both the first arc-shaped plate and the second arc-shaped plate into a C-shape with an included angle of approximately 270°. Accordingly, the first arc-shaped plate and the second arc-shaped plate cooperate to shield the annular groove.

[0014] In an embodiment of the present invention, a Type-C USB connector is used as the first USB connector, and a USB connector other than the Type-C USB connector is used as the second USB connector. Attached Figure Description

[0016] To facilitate understanding of the present invention, a detailed description is provided below with reference to the accompanying drawings and embodiments. The drawings show only a portion of the embodiments of the present invention, not all of them. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0018] Figure 1 The card reader 10 of the present invention has an elongated body 100, with a large opening 1020 and a narrow slot 1016 formed on opposite sides of the body 100 (e.g., Figure 10 As shown), a first USB connector module 30 and a second USB connector module 40 of different specifications are provided at opposite ends inside the main body 100. The first USB connector module 30 and the second USB connector module 40 are respectively connected to the first rotating member 50 and the second rotating member 60. The user can operate the first rotating member 50 to rotate the first USB connector module 30 out of the opening 1020 and be positioned by the positioning part 10120, or operate the second rotating member 60 to rotate the second USB connector module 40 out of the opening 1020 and be positioned by the positioning part 10120.

[0019] Figure 2 and Figure 3 The display body 100 consists of a base 101 and a housing 102. The housing 102 is a hollow shell with an opening 1020 on one side and a circular through hole 1021 on the top. A central shaft 1014 is erected in the center of the base 101. The first USB connector module 30 and the second USB connector module 40 are respectively arranged on opposite sides of the base 101 with the central shaft 1014 as the center, and are arranged in a straight line when they are completely housed in the body 100. A first rotating member 50 is connected to the first USB connector module 30, and a second rotating member 60 is connected to the second USB connector module 40. A positioning part 10120 is provided on one side of the base 101 in the same direction as the opening 1020. The end of the central shaft 1014 is formed as a non-circular shape and passes through the slot 201 of the circular seat 20, fixing the seat 20 in the through hole 1021. The outer diameter of the seat 20 is smaller than the inner diameter of the through hole 1021, so that an annular ring is formed between the outer edge of the seat 20 and the inner edge of the through hole 1021.

[0020] Figure 4The base 101 structure further shows that it includes a lower shell 1011 and an upper shell 1012, which are fastened together by screws 1013 to form the base 101. A circular boss 10123 is formed in the center of the upper shell 1012, and a protrusion 10124 is formed on one side of the boss 10123. The aforementioned positioning part 10120 is disposed at the center of the side of the boss 10123, and is preferably integrally formed with the boss 10123. For example, a notch is formed at the center of the side of the boss 10123, and an elastic part 10121 with a positioning block 10122 on the surface is integrally formed in the notch. The opposite sides of the elastic part 10121 are connected to the boss 10123 only by thinner rods, and the rest is suspended, thereby giving the elastic part 10121 appropriate elasticity. A main circuit board 1015 is disposed between the upper shell 1012 and the lower shell 1011. A plurality of first conductive terminals 10151 arranged linearly along the width direction of the body 100 are electrically connected to the upper surface of the main circuit board 1015, and a plurality of second conductive terminals 10152 arranged linearly along the length direction of the body 100 are electrically connected to the lower surface of the main circuit board 1015. Figure 9 (As shown); wherein, the first conductive terminal 10151 is closer to the opening 1020, and the second conductive terminal 10152 is closer to the slot 1016. The central shaft 1014 passes through the shaft hole of the upper shell 1012 from the inside of the base 101 and stands upright at the center of the boss 10123.

[0021] Figure 5 and Figure 6 The structure of the first USB connector module 30 and the first rotating member 50 and their combination relationship are further shown; wherein, the first USB connector module 30 includes a first circuit board 302, a first USB connector 301 electrically connected to the first circuit board 302, and a first fixing block 303, the first circuit board 302 being provided with a plurality of first conductive metals 3022 (such as... Figure 10 As shown, that is, located in Figure 5 The lower surface of the first circuit board 302 shown is shown, and the first circuit board 302 is provided with a plurality of holes 3021; ​​in an embodiment of the present invention, a USB Type-C connector is used as the first USB connector 301.

[0022] The first fixing block 303 serves as a component connecting the first rotating member 50 and the first USB connector module 30. It is formed as a block and has multiple holes 3032 corresponding to the aforementioned holes 3021. A first arc-shaped rail 3031 is formed on one side surface, and one corner is chamfered to form a first bevel 3033, for example, a chamfer of 45°.

[0023] The first rotating member 50 is preferably integrally formed having a first arcuate plate 502, and a first handle 503 (e.g., a handle) is formed on the upper surface of the first arcuate plate 502. Figure 5 (As shown in the L-shaped handle), preferably, the first arc-shaped plate 502 is formed in a C-shape; the plate body connected to the bottom of the first arc-shaped plate 502 is provided with a plurality of first screw holes 505 corresponding to the aforementioned holes 3021, 3032, and a first USB connector mounting base 501 is connected to the side of the plate body. The side of the first USB connector mounting base 501 and the outer edge of the first arc-shaped plate 502 form a first arc-shaped groove 504. The curvature of the first arc-shaped groove 504 is the same as the curvature of the first arc-shaped rail 3031 formed on the first fixing block 303, so that the first... An arc-shaped rail 3031 can be fitted into the first arc-shaped groove 504; the first USB connector mounting base 501 has a first inner space 5011 for mounting the first USB connector 301. After the first USB connector 301 is inserted into the first inner space 5011 and protrudes outward, it is fixed by screws 304 passing through the aforementioned holes 3021 and 3032 and locking into the first screw hole 505. Alternatively, pins, rivets, hooks, etc., can be used to replace the screws 304 to complete the assembly of the first rotating part 50 and the first USB connector module 30. Furthermore, two first positioning protrusions 506 are formed at the middle position of the lower edge of the first USB connector mounting base 501, and a first positioning recess 507 is formed between the two first positioning protrusions 506 for matching and positioning with the positioning block 10122.

[0024] Figure 7 and Figure 8 The structure of the second USB connector module 40 and the second rotating member 60 and their combination relationship are further shown; wherein, the second USB connector module 40 includes a second circuit board 402, a second USB connector 401 electrically connected to the second circuit board 402, and a second fixing block 403, and the second circuit board 402 is provided with a plurality of second conductive metals 4022 (such as... Figure 10 As shown, that is, located in Figure 7 The lower surface of the second circuit board 402 shown is shown, and the second circuit board 402 is provided with a plurality of holes 4021; in an embodiment of the present invention, a USB connector other than a USB Type-C connector (e.g., Type-A) is used as the second USB connector 401.

[0025] The second fixing block 403 serves as a component connecting the second rotating member 60 and the second USB connector module 40. It is formed as a block and has multiple holes 4032 corresponding to the aforementioned holes 4021. A second arc-shaped rail 4031 is formed on one side surface, and a corner is chamfered to form a second bevel 4033, for example, a chamfer of 45°.

[0026] The second rotating member 60 is preferably integrally formed having a second arcuate plate 602, and a second handle 603 (e.g., a handle) is formed on the upper surface of the second arcuate plate 602. Figure 7(As shown in the L-shaped handle), preferably, the second arc-shaped plate 602 is formed in a C-shape; the plate body connected to the lower part of the second arc-shaped plate 602 is provided with a plurality of second screw holes 605 corresponding to the aforementioned holes 4021, 4032, and a second USB connector mounting base 601 is connected to the side of the plate body. The side of the second USB connector mounting base 601 and the outer edge of the second arc-shaped plate 602 form a second arc-shaped groove 604. The curvature of the second arc-shaped groove 604 is the same as the curvature of the second arc-shaped rail 4031 formed on the second fixing block 403, so that the second... The two arc-shaped rails 4031 can be matched within the second arc-shaped groove 604; the second USB connector mounting base 601 has a second inner space 6011 for mounting the second USB connector 401. After the second USB connector 401 is inserted into the second inner space 6011 and protrudes outward, it is fixed by screws 404 passing through the aforementioned holes 4021 and 4032 and locking into the second screw hole 605. Alternatively, pins, rivets, hooks, etc., can be used to replace the screws 404 to complete the assembly of the second rotating part 60 and the second USB connector module 40. Furthermore, two second positioning protrusions 606 are formed at the middle position of the lower edge of the second USB connector mounting base 601, and a second positioning recess 607 is formed between the two second positioning protrusions 606 for matching and positioning with the positioning block 10122. Furthermore, both the first arc plate 502 and the second arc plate 602 are formed into a C shape with an included angle of approximately 270°, and the height of the second arc plate 602 relative to the second USB connector mounting base 601 is greater than the height of the first arc plate 502 relative to the first USB connector mounting base 501, so that when the first arc plate 502 and the second arc plate 602 are disposed in the through hole 1021, they are staggered from each other in the height direction to cover the annular through hole.

[0027] The first USB connector module 30 and the first rotating component 50, together with the second USB connector module 40 and the second rotating component 60, are installed between the base 101 and the outer shell 102. This arrangement ensures that both the first handle 503 and the second handle 603 protrude from the through-hole 1021 of the outer shell 102. Simultaneously, the first arc-shaped plate 502 and the second arc-shaped plate 602 are staggered in height to cover the annular through-hole 1021. The combined structure is as follows: Figures 9 to 11 As shown.

[0028] Through the aforementioned card reader 10 of the present invention, the user needs to insert the chip card 80 (e.g., Figure 14(As shown) When connected to the USB Type-C interface of the electronic device 70 via the USB Type-C connector, the first handle 503 can be operated to rotate the first rotating member 50 to rotate the first USB connector 301 out of the opening 1020 until the first positioning recess 507 and the positioning block 10122 correspond to the predetermined position. Then, the elastic force of the elastic part 10121 is used to make the positioning block 10122 embed into the first positioning recess 507 to position the first USB connector 301. At the same time, the plurality of first conductive metals 3022 provided on the lower surface of the first circuit board 302 simultaneously make electrical contact with each of the first conductive terminals 10151 (e.g., Figure 12 As shown), in this state, the centerline of the port of the first USB connector 301 is perpendicular to the length direction of the body 100, and the first inclined side 3033 of the corner of the first fixing block 303 abuts against the second inclined side 4033 of the corner of the second fixing block 403, so that the first USB connector 301 and the second USB connector 401 are kept at a 90° angle; the slot 1016 located on the opposite side of the body 100 is for inserting the chip card 80, so that the chip on the chip card 80 and each of the second conductive terminals 10152 are electrically in contact, that is, the chip card 80 can transmit and receive electronic data through the main circuit board 1015 and the USB Type-C interface of the electronic device 70. When not in use, the first rotating member 50 can be reversed to store the first USB connector 301 into the body 100.

[0029] Similarly, when a user needs to connect a chip card to the USB interface of an electronic device via a USB connector other than a USB Type-C connector, the second handle 603 can be operated to rotate the second rotating member 60 while both the first USB connector 301 and the second USB connector 401 are housed within the body 100. This rotates the second USB connector 401 out of the opening 1020 until the second positioning recess 607 and the positioning block 10122 align at a predetermined position. Then, the elastic force of the elastic part 10121 causes the positioning block 10122 to embed into the second positioning recess 607, thus positioning the second USB connector 401. At the same time, multiple second conductive metals 4022 on the lower surface of the second circuit board 402 simultaneously make electrical contact with each of the first conductive terminals 10151 (e.g., ...). Figure 13As shown), in this state, the centerline of the port of the second USB connector 401 is perpendicular to the length direction of the body 100, and the second inclined edge 4033 at the corner of the second fixing block 403 abuts against the first inclined edge 3033 at the corner of the first fixing block 303, so that the second USB connector 401 and the first USB connector 301 are kept at a 90° angle; the slot 1016 located on the opposite side of the body 100 is for inserting the chip card 80, so that the chip on the chip card 80 and each of the second conductive terminals 10152 are electrically in contact, that is, the chip card 80 is electrically connected to the USB interface of the electronic device 70 through the main circuit board 1015, and can transmit and receive electronic data. When not in use, the second rotating member 60 can be reversed to store the second USB connector 401 into the body 100.

[0030] Since the first USB connector 301 or the second USB connector 401 is fully exposed outside the body 100, the first inclined edge 3033 of the first fixing block 303 and the second inclined edge 4033 of the second fixing block 403 will abut against each other. Therefore, when switching from using the first USB connector 301 to using the second USB connector 401, the second rotating member 60 can be directly operated to rotate the second USB connector 401 out of the body 100. At the same time, the second fixing block 403 will push the first fixing block 303 to rotate, thus retracting the first USB connector 301 into the body 100. Alternatively, when switching from using the second USB connector 401 to using the first USB connector 301, the first rotating member 50 can be directly operated to rotate the first USB connector 301 out of the body 100. At the same time, the first fixing block 303 will push the second fixing block 403 to rotate, thus retracting the second USB connector 401 into the body 100. That is, the first fixing block 303 and the second fixing block 403 can push and rotate each other via the first inclined side 3033 and the second inclined side 4033, so that while rotating the first USB connector 301 out of the body 100, the second USB connector 401 exposed outside the body 100 is rotated into the body 100, or while rotating the second USB connector 401 out of the body 100, the first USB connector 301 exposed outside the body 100 is rotated into the body 100.

[0031] Figures 15 to 17 To illustrate the second embodiment of the aforementioned positioning part 10120; in the aforementioned first embodiment, the positioning part 10120 uses the elasticity of the elastic part 10121 to position the positioning block 10122 and the first positioning recess 507 or the second positioning recess 607 to engage and position each other; however, in the second embodiment, the first USB connector 301 and the second USB connector 401 can be fixed or not by manual means.

[0032] like Figure 15 As shown, a second embodiment of the positioning part 10120 may include a latch 10125 and a push button 10126 slidably disposed on the body 100, and the latch 10125 and the push button 10126 are connected to each other; by the user manually operating the push button 10126, the latch 10125 can be controlled to extend out of the body 100 or retract into the body 100. Accordingly, when the first USB connector 301 or the second USB connector 401 is rotated out of the body 100 and to a predetermined positioning position, the first positioning recess 507 of the first rotating member 50 or the second positioning recess 607 of the second rotating member 60 corresponds to the latch 10125. At this time, by pushing the push button 10126, the latch 10125 is inserted into the first positioning recess 507 to position the first USB connector module 30 (e.g., Figure 16 (As shown), or by inserting the latch 10125 into the second positioning recess 607 to position the second USB connector module 40, pushing the push button 10126 in the opposite direction will disengage the latch 10125 from the first positioning recess 507 or the second positioning recess 607, thus releasing the positioning (as shown). Figure 17 (As shown).
