[0003] This application relates to the field of wallet technology, and in particular to a card holder. Background Technology

[0004] To facilitate the storage of multiple cards such as credit cards, ID cards, driver's licenses, access cards, transportation cards, and membership cards, specialized card holders exist in related technologies. These card holders typically dispense cards in a stepped fashion, where multiple cards are stacked in a tiered manner outside the card dispenser. However, due to the significant overlap between the cards after dispensing, they obscure each other, making it difficult for users to identify the required card. Furthermore, the small area of ​​each card protruding from its adjacent counterparts also hinders the user's ability to retrieve the cards.

[0005] Application content

[0006] This application aims to at least partially address one of the technical problems existing in related technologies. To this end, this application proposes a card holder that reduces the overlapping area between cards after dispensing, thereby facilitating user identification and retrieval of the required cards.

[0007] A card holder according to an embodiment of this application includes: a housing having a receiving space for accommodating a card stack consisting of at least two stacked cards, one sidewall of the housing having a card ejection port for releasing the card stack; and a card ejector including a card arm located within the receiving space, the card arm being configured to switch from a retracted position to a released position when the card ejector is actuated by a user, such that a portion of the card stack is released through the card ejection port to the outside of the housing, and at least two of the cards are stacked in a fan-shaped dispersion manner.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0034] To facilitate the storage of multiple cards such as credit cards, ID cards, driver's licenses, access cards, transportation cards, and membership cards, card holders specifically designed for holding multiple cards exist in related technologies. However, the card holders in these technologies use a stepped dispensing method, where multiple cards are stacked in a stepped manner outside the card dispenser. This method results in a large overlap between the cards, making it difficult for users to identify and retrieve the cards they need. To solve the above technical problem, this application provides a card holder that reduces the overlap between cards after dispensing, thereby making it easier for users to identify and retrieve the cards they need. The card holder of this application embodiment is described below with reference to the accompanying drawings.

[0035] Figure 1 is a schematic diagram of the structure of a card holder according to an embodiment of this application, wherein the card stack is in a released state. Figure 2 is a schematic diagram of the structure of the card holder in the embodiment shown in Figure 1 after the front wall is hidden. Figure 3 is a front view of the card holder in the embodiment shown in Figure 1 after the front wall is hidden. Referring to Figures 1, 2 and 3, the card holder according to an embodiment of this application includes a housing 100 and a card ejector 200. The interior of the housing 100 is formed as a receiving space 110, which can accommodate multiple cards 310, such as two, three, six or seven cards; the types of cards 310 can be credit cards, ID cards, driver's licenses, access cards, transportation cards, membership cards, etc. Multiple cards 310 are stacked sequentially along their thickness direction to form a card stack 300, which can be completely stored inside the housing 100. The interior of the housing 100 can simultaneously accommodate multiple cards 310 of different types, meeting the user's needs for storing different types of cards 310. Card ejector 200 is used to release the card stack 300 outside the housing 100. To facilitate the release of the card stack 300, one side wall of the housing 100 is provided with a card ejection port 111. The card ejection port 111 communicates with the receiving space 110 and is located on one side of the receiving space 110. The card stack 300 is released outside the housing 100 through the card ejection port 111. Referring to the direction of FIG2, the card ejection port 111 can be located on the upper end wall (i.e., top wall 113) of the housing 100, or on the left side wall 115 or right side wall 116 of the housing 100, or on the lower end wall (i.e., bottom wall 114) of the housing 100. As an alternative embodiment, the card ejection port 111 can be arranged across two adjacent side walls, for example, formed at the junction of the top wall 113 and the right side wall 116.

[0036] Referring to Figures 2 and 3, the card ejector 200 includes a card arm 210 located within the receiving space 110. The card arm 210 is moved by the card ejector 200, and its movement within the receiving space 110 has a retracted position and a released position. When the user actuates the card ejector 200, the card arm 210 is driven to switch from the retracted position to the released position. When the card arm 210 is in the released position, the card stack 300 is pushed out of the card outlet 111 under the action of the card arm 210, so that part of the card stack 300 is released to the outside of the housing 100 through the card outlet 111. It can be understood that at this time, the area of ​​each card 310 released to the outside of the housing 100 is different, that is, two adjacent cards 310 are not completely overlapping, so as to ensure that the user can identify the card 310 by the exposed features of the card 310.

[0037] In this embodiment, after the card ejector 200 is activated by the user, multiple cards 310 are stacked in a fan-shaped arrangement in the card stack 300 outside the housing 100. For example, the fan-shaped arrangement can be achieved by multiple cards 310 rotating around the same axis of rotation to achieve staggered opening, or by multiple cards 310 rotating around different axes of rotation to achieve staggered opening, or by multiple cards 310 rotating around the axis of rotation while moving along the plane containing the surface of the card 310 (i.e., the plane perpendicular to the thickness direction of the card 310) to achieve staggered opening.

[0038] In order to achieve a fan-shaped distributed stacking of the card stack 300 in the released state, the housing 100 has at least one limiting part (e.g., inner convex surface 121, second abutment surface 131, or first abutment surface 141). When the card arm 210 drives the card stack 300 to be released out of the card outlet 111, under the blocking, constraint, or guiding effect of the limiting part, different cards 310 will rotate at different angles or deviate by different distances.

[0039] In this embodiment, the multiple cards 310 released by the card holder are stacked in a fan-shaped, dispersed manner. Compared to the stepped stacking method in related technologies, this reduces the overlap area between adjacent cards 310, resulting in a larger area of ​​the cards 310 exposed within the user's field of vision. This facilitates the user's quick identification of the card 310 needed. Furthermore, the larger exposed area of ​​the cards 310 also makes it easier for the user to select the desired card 310 with their fingers, making it particularly suitable for users with larger fingers.

[0040] Referring to Figures 1 and 3, the solid line shows card 310 in the retracted state, and the dashed line shows card 310 in the released state. The vertical direction is defined as the up-down direction shown in Figure 3, and the horizontal direction is defined as the left-right direction shown in Figure 3; these definitions will be used for further understanding below. The card dispensing slot 111 and card arm 210 are arranged longitudinally at intervals. In this embodiment, the card dispensing slot 111 is located on the top wall 113 of the housing 100, and the card arm 210 is located near the bottom wall 114 of the housing 100. The housing 100 has an opening 112 on one side along the horizontal direction. In this embodiment, the opening 112 is located on the left side wall 115 of the housing 100. When the card stack 300 is in the released state, one of the two corner edges of the card 310 near the card dispensing slot 111 protrudes through the opening 112, and the other protrudes through the card dispensing slot 111. It should be noted that the area of ​​the corner edge protruding from the opening 112 of different cards 310 in the card stack 300 is basically different. For some cards 310, only part of the corner edge protrudes from the opening 112, while for others, the entire corner edge protrudes from the opening 112, and for still others, the corner edge protrudes to the opening 112 but is not exposed outside the housing 100. The area of ​​the corner edge protruding from the card outlet 111 of different cards 310 is also basically different. Therefore, when a user removes the corresponding card 310 in the released state of the card stack 300, they can simply rotate it slightly towards the opening 112 to remove the card 310 from the card outlet 111.

[0041] Referring to Figures 2 and 3, the card 310 has an upper left corner edge 311 and an upper right corner edge 312 on the side near the card dispensing slot 111. The upper left corner edge 311 is an arc-shaped edge located at the upper left corner of the card 310, and the upper right corner edge 312 is an arc-shaped edge located at the upper right corner of the card 310. The upper left corner edge 311 protrudes from the opening 112, and the upper right corner edge 312 protrudes from the card dispensing slot 111. As an alternative embodiment, the upper left corner edge 311 of the card 310 protrudes from the card dispensing slot 111, and the upper right corner edge 312 protrudes from the opening 112.

[0042] Figure 4 is an exploded view of the card holder of the embodiment shown in Figure 2. Referring to Figures 2, 3, and 4, in one embodiment of the card holder of this application, the housing 100 includes a first sidewall 120 and a second sidewall 130 arranged laterally at intervals. The first sidewall 120 is the left sidewall 115 shown in Figure 2, and the second sidewall 130 is the right sidewall 116 shown in Figure 2. An opening 112 is provided on the left sidewall 115. The left sidewall 115 has an inner convex surface 121 at the opening 112, which is longitudinally opposite to the card slot 111. The inner convex surface 121 is located below the card slot 111. In this embodiment, the inner convex surface 121 is located on the lower end face of the opening 112 and is arranged towards the receiving space 110. The inner convex surface 121 is configured to extend from the outside of the left sidewall 115 in a direction opposite to the card slot 111 towards the inner wall of the receiving space 110, that is, the inner convex surface 121 is formed in the thickness direction of the left sidewall 115. In this embodiment, the inner convex surface 121 is configured as an outer convex curved surface, such as a circular arc surface, an elliptical arc surface, etc. It can also be a collection of at least one curved surface and at least one plane, or a collection of multiple curved surfaces, or a collection of multiple planes, and is not specifically limited here.

[0043] The housing 100 also includes a constraint member 140 formed between the slot 111 and the opening 112. The constraint member 140 is located on the left side wall 115 of the housing 100, preferably near the slot 111; or on the top wall 113 of the housing 100, preferably near the opening 112; or at the junction of the left side wall 115 and the top wall 113. In this embodiment, the first abutting surface 141 is configured as a convex curved surface, such as a circular arc surface, an elliptical arc surface, etc., or it can be a combination of at least one curved surface and at least one plane, or a combination of multiple curved surfaces, or a combination of multiple planes, which is not specifically limited here. The constraint member 140 has a first abutting surface 141, which is located on the side of the constraint member 140 facing the receiving space 110.

[0044] Referring to Figure 3, the side of card 310 closest to the first sidewall 120 is the left side 315, and the side of card 310 closest to the card outlet 111 is the upper side 316. The card stack 300 is configured such that during the process of the card arm 210 moving from the retracted position to the released position, the left side 315 of card 310 rotates around the inner convex surface 121, and the upper side 316 of card 310 slides against the first contact surface 141. Referring to Figure 2, when the card ejector 200 is actuated by the user, the card arm 210 is driven to rotate from the retracted position to the released position. At this time, the left side 315 of card 310 abuts against the inner convex surface 121 and rotates under the support of the inner convex surface 121, causing card 310 to rotate approximately to the left around the contact point between the left side 315 and the inner convex surface 121; at this time, the upper side 316 of card 310 abuts against the first contact surface 141 as card 310 rotates, causing card 310 to slide approximately to the left. Under the combined action of the inner convex surface 121 and the first abutting surface 141, the upper left corner 311 of the card 310 passes through the opening 112, and the upper right corner 312 passes through the card outlet 111; moreover, the rotation angle and sliding distance of different cards 310 in the card stack 300 are different, so that multiple cards 310 present a fan-shaped distributed stacking state.

[0045] Referring to FIG3, another embodiment of the housing 100 of this application includes a first sidewall 120 and a second sidewall 130 arranged laterally at intervals. The first sidewall 120 is the left sidewall 115 shown in FIG3, and the second sidewall 130 is the right sidewall 116 shown in FIG3. The left sidewall 115 has an inner convex surface 121. The description of the inner convex surface 121 can be understood with reference to the foregoing embodiments, and will not be repeated here to avoid repetition. The right sidewall 116 has a second abutment surface 131 on the side facing the receiving space 110. The second abutment surface 131 is used to abut against the edge of the card 310, thereby applying friction to the card 310, making it difficult for the card 310 to fall out of the card slot 111. The side of card 310 closest to the left side wall 115 is called the left side 315. The side of card 310 closest to the second side wall 130 has an upper right corner 312 and a lower right corner 313. The upper right corner 312 is close to the card outlet 111, and the lower right corner 313 is close to the card arm 210.

[0046] The card stack 300 is configured such that during the process of the card arm 210 moving from the retracted position to the released position, the left side 315 of the card 310 rotates around the inner convex surface 121, and the corner edge of the card 310 near the second sidewall 130 slides against the second contact surface 131. During the process of the card arm 210 being driven from the retracted position to the released position, at this time, the left side 315 of the card 310 abuts against the inner convex surface 121 and rotates under the support of the inner convex surface 121, so that the card 310 rotates approximately to the left around the contact point between the left side 315 and the inner convex surface 121; at the same time, the lower right corner 313 of the card 310 abuts against the second contact surface 131 when the card 310 rotates, the upper left corner 311 of the card 310 passes through the opening 112, and the upper right corner 312 passes through the card outlet 111. The rotation angle and offset distance of different cards 310 in the card stack 300 are different, so that multiple cards 310 present a fan-shaped distributed stacking state. Under the constraint of the inner convex surface 121 and the second abutment surface 131, the card 310 is continuously subjected to appropriate frictional force throughout the rotation process. During the release process, the card 310 will not easily fall out of the housing 100, and in the released state, the card 310 can also maintain a certain frictional force with the housing 100, and will not fall out of the housing 100 due to the rotational inertia or slide back into the housing 100 due to its own weight. Moreover, the user will receive a certain damping force feedback when actuating the card ejector 200, resulting in a better operating feel. It should be noted that when the number of cards 310 in the receiving space 110 is close to the maximum capacity, due to the large number of cards 310, in order to ensure that all cards 310 are dispersed in a fan-shaped state in the released state, the rotation angle of some cards 310 is larger, so that the lower right corner edge 313 of these cards 310 may detach from the second abutment surface 131.

[0047] Referring to Figures 3 and 4, in another embodiment of the card holder of this application, the second sidewall 130 has a first friction element 410, which is disposed on the inner side of the second sidewall 130, i.e., within the receiving space 110. The first friction element 410 can be fixed to the second sidewall 130 by means of adhesive bonding, interference fit, snap-fit, or embedded installation. The first friction element 410 can be disposed in a portion of the inner sidewall 130, which can be continuous or discontinuous; or, the first friction element 410 can be disposed in the entire inner sidewall 130. The side of the first friction element 410 facing the card stack 300 is configured as a second abutment surface 131. The material of the first friction element 410 can be a soft material such as felt, silicone, or rubber, or a hard material such as a spring or a snap fastener. All of the above materials have a certain degree of elasticity, and the first friction element 410 can provide friction to the card 310 through elastic deformation. As an alternative embodiment, the first friction element 410 may also be made of other materials that can provide friction to the card 310 toward the receiving space 110.

[0048] In this embodiment, an installation groove 132 is provided on the inner side of the second sidewall 130. The installation groove 132 is recessed from the inner side of the second sidewall 130. The first friction element 410 is installed in the installation groove 132 by means of adhesive, snap-fit, etc., so as to achieve a more stable installation of the first friction element 410, making it difficult for the first friction element 410 to separate from the second sidewall 130, causing the second abutment surface 131 to fail.

[0049] Referring to Figure 3, the second abutment surface 131 is configured as an inwardly concave arc surface. The arc surface is formed on the inner side of the second sidewall 130, and the extension direction of the arc surface is adapted to the movement trajectory of the lower right corner edge 313 of the card 310. Therefore, the lower right corner edge 313 of the card 310 can continuously abut against the second abutment surface 131 during rotation. The card 310 is subject to frictional constraint by the second abutment surface 131, and the force of this frictional constraint is more uniform, which is beneficial to the stability of the card 310 during rotation and effectively suppresses problems such as jamming or stuckness of the card 310.

[0050] Referring to FIG3, the second abutment surface 131 is configured to abut at least a portion of the side edges of the cards 310 when the card stack 300 is in the retracted state. In this embodiment, when the card stack 300 is in the retracted state, all cards 310 in the card stack 300 are located within the receiving space 110. The upper right corner 312 and lower right corner 313 of the cards 310 can be constrained by the second abutment surface 131, thereby limiting the cards 310 and suppressing the tendency of the card stack 300 to fall out of the housing 100. As an alternative embodiment, when the card stack 300 is housed in the receiving space 110, the second abutment surface 131 can also limit the card stack 300 in the retracted state by abutting only the upper right corner 312 or the lower right corner 313 of the cards 310, or by abutting only the right side 319 of the cards 310.

[0051] Figure 5 is a structural schematic diagram of a card holder according to another embodiment of this application. Figure 6 is a front view of the card holder in the embodiment shown in Figure 5 after the front wall is hidden, wherein the card arm is in the retracted position and the card is in the released state. Figure 8 is an exploded view of the card holder in the embodiment shown in Figure 5. Referring to Figures 5, 6, and 8, and with reference to Figure 2 for understanding, the card arm 210 has a card ejection feature 220, which is used to engage with the lower side edge 318 of the card 310. The card ejection feature 220 includes a plurality of guide steps 221 arranged along the stacking direction of the cards 310. The thickness of the plurality of guide steps 221 is adapted to the thickness of the card 310. Each card 310 is engaged by one or more guide steps 221 and driven to rotate. The guide surface of the guide step 221 that abuts against the side edge of the card 310 can be a plane, an inclined plane, or an arc surface, or a combination of an arc surface and a plane or an inclined plane. For example, the thickness of the guide step 221 is approximately the same as the thickness of the card 310, that is, 0.9 to 1.1 times the thickness of the card 310; the thickness of the guide step 221 can also be approximately half the thickness of the card 310, that is, 0.4 to 0.6 times the thickness of the card 310.

[0052] Multiple guide steps 221 are configured to guide corresponding cards 310 to abut and rotate around the inner convex surface 121 during the process of the card arm 210 moving from the retracted position to the released position. This ensures that when the card stack 300 is partially released to the outside of the housing 100, two stacked cards 310 are stacked in a manner that is offset by rotation in two mutually perpendicular directions, such as offset longitudinally and laterally. Referring to Figure 8 and with the aid of Figure 2, each card 310 located in the receiving space 110 abuts and rotates around a corresponding position on the inner convex surface 121. The rotation fulcrum of each card 310 can coincide or be offset in the front-back direction of Figure 8. Moreover, the rotation fulcrum of the left side 315 of each card 310 can be the same or different. The lower side 318 of each card 310 is engaged at a different position by the card ejection feature 220. Therefore, after the card arm 210 rotates and releases the card 310, the rotation angle of each card 310 after release is different. The cards 310 in the card stack 300 located outside the housing 100 are offset horizontally and vertically. After adjacent cards 310 are rotated and offset horizontally and vertically respectively, the overlap area of ​​two stacked cards 310 is effectively reduced, resulting in a larger area of ​​the cards 310 exposed within the user's field of vision, which helps the user quickly identify the required card 310. Furthermore, the larger exposed area of ​​the cards 310 also makes it easier for the user to select the required card 310 with their finger. It should be noted that non-adjacent cards 310 can also be configured to overlap horizontally, as long as it does not affect the user's ability to identify the cards 310.

[0053] As an alternative embodiment, the card ejection feature 220 is configured as a sloping structure. With the engagement of the sloping structure, each card 310 of the card stack 300 can be driven to rotate by different areas of the sloping structure, so that when the card stack 300 is released, every two adjacent cards 310 rotate and are offset in two mutually perpendicular directions, such as offset in the longitudinal and transverse directions.

[0054] Figure 9 is an enlarged schematic diagram of the clamping arm in Figure 8. Referring to Figures 8 and 9, the clamping arm 210 is generally a strip-shaped structure, so the extension direction of each guide step 221 is the same as the length direction of the clamping arm 210. The clamping arm 210 has a first end 211 and a second end 212 at its two ends in the length direction, respectively. The first end 211 is rotatably connected to the housing 100, and the first end 211 has the axis of rotation of the clamping arm 210. The first end 211 can be installed on the housing 100 through a first rotating shaft 213. The first rotating shaft 213 and the housing 100 are fixedly connected. The first end 211 has a first hole that fits on the outer periphery of the first rotating shaft 213, and the clamping arm 210 is rotatably connected to the first rotating shaft 213 through the first hole. As an alternative embodiment, the first end 211 has a first rotating shaft 213, and the first rotating shaft 213 is rotatably connected between two opposite second holes inside the housing 100.

[0055] Referring to Figure 6, it should be noted that when the locking arm 210 is in the retracted position, it is generally parallel to the bottom wall 114; the locking arm 210 can rotate counterclockwise along the rotation axis (i.e., rotate towards the inner convex surface 121) to achieve the movement from the retracted position to the released position; the locking arm 210 can also rotate clockwise along the rotation axis (i.e., rotate towards the second abutment surface 131) to achieve the movement from the retracted position to the released position.

[0056] The second end 212 is located within the receiving space 110. The second end 212 is the end of the card arm 210 furthest from its rotation fulcrum. Multiple guide steps 221 are provided in the direction from the first end 211 to the second end 212. Each guide step 221 has a guide ramp 2211. The guide ramp 2211 gradually abuts against the lower side 318 of the card 310 as the card stack 300 rotates, and completely abuts against the card 310 when the card stack 300 is in the released state. At least some of the guide steps 221 have different ramp angles on their guide ramps 2211. When the ramp angles of the guide ramps 2211 are configured differently, after the card 310 rotates under the drive of the guide ramps 2211, the card stack 300 exhibits a more dispersed stacking state in the released state, such as a fan-shaped dispersion.

[0057] Figure 10 is an enlarged front view of the clamping arm in Figure 8. Referring to Figure 10 and with the aid of Figure 6, in this embodiment, the first end 211 of the clamping arm 210 is rotatably connected to the first rotating shaft 213. The extension direction of the guide step 221 is the same as the extension direction of the clamping arm 210. The guide slope 2211 is located on the end face of the guide step 221 away from the first rotating shaft 213, and the guide slope 2211 is inclined towards the exit port 111. From the first end 211 to the second end 212, the slope of the guide slope 2211 of the adjacent parts of the guide step 221 gradually decreases. In this embodiment, the first end 211 of the card arm 210 is located to the left of the second end 212. The slope between the guide slope 2211 and the horizontal plane is smaller the closer it is to the second end 212 (as shown in Figure 10, the slope α2 is smaller than the slope α1). In the direction from front to back, the length of the multiple guide steps 221 gradually increases, and the slope of the corresponding guide slope 2211 gradually decreases. The card arm 210 rotates counterclockwise. After the multiple guide slopes 2211 drive the cards 310 stacked in the front and back directions to rotate, the rotation angle of the cards 310 in front will be smaller than the rotation angle of the cards 310 behind, thus presenting a fan-shaped dispersed stack, and making it convenient for users to identify the features of each card 310 from the front.

[0058] Referring to Figures 6 and 8, and aided by Figures 2 and 3, the card ejector 200 also includes a first actuator 230. The first actuator 230 is for manual operation by the user and is drive-connected to the card arm 210 to control its movement. For ease of user operation, a portion of the first actuator 230 is located outside the housing 100. The housing 100 includes a top wall 113 and a bottom wall 114 arranged longitudinally at intervals. The card ejection port 111 is located on the top wall 113, and a receiving groove 1141 is provided on the outer side of the bottom wall 114, communicating with the receiving space 110. When the card arm 210 is in the retracted position, the first actuator 230 is accommodated within the receiving groove 1141, resulting in a flat and simple appearance for the card holder, and minimizing its space requirements when placed in a trouser pocket. When the card stack 300 needs to be released, the user operates the first actuator 230 to move, thereby driving the card arm 210 to rotate and partially release the card 310 outside the housing 100. Preferably, in order to facilitate operation of the first actuator 230, when the card arm 210 is in the retracted position, part of the structure of the first actuator 230 is configured to be exposed in the receiving groove 1141.

[0059] In this embodiment, the extending direction of the receiving groove 1141 is parallel to the bottom wall 114. The first actuator 230 includes a strip-shaped operating arm 231, which is located on the extension line of the locking arm 210 and is rigidly connected to the locking arm 210. When the locking arm 210 is in the retracted position, the end of the operating arm 231 away from the locking arm 210 protrudes from the receiving groove 1141. This part of the structure is configured as the operating part 2311. The surface of the operating part 2311 may be provided with features such as raised strips or grooves to increase friction, making it convenient for the user to manually operate the card ejector 200. When the user operates the first actuator 230, they only need to press down on the operating part 2311 to rotate it downwards, at which time the operating arm 231 leaves the receiving groove 1141.

[0060] As an alternative embodiment, the first actuator 230 is connected to the locking arm 210 via a connecting member such as a linkage, thereby achieving indirect transmission of the locking arm 210 and driving the locking arm 210 to rotate to the release position. For example, the first actuator 230 is located on the front wall 117, right side wall 116, or left side wall 115 of the housing 100.

[0061] Referring to FIG14, in another embodiment of the clamping arm 210 of this application, the first end 211 of the clamping arm 210 has a first pivot 213, the extension direction of the guide step 221 is the same as the extension direction of the clamping arm 210, and the guide slope 2211 is located on the end face of the guide step 221 away from the first pivot 213, and the guide slope 2211 is inclined toward the outlet 111. From the first end 211 to the second end 212, the slope of the guide slope 2211 of the adjacent part of the guide step 221 gradually increases. In this embodiment, the second end 212 of the card arm 210 is located to the left of the first end 211. The slope between the guide slope 2211 and the horizontal plane is greater the closer to the second end 212. In the direction from front to back, the length of the multiple guide steps 221 gradually increases, and the slope of the corresponding guide slope 2211 gradually increases. The card arm 210 rotates in the clockwise direction. After the multiple guide slopes 2211 drive the cards 310 stacked in the front and back directions to rotate, the rotation angle of the cards 310 in front will be smaller than the rotation angle of the cards 310 behind, thus presenting a fan-shaped dispersed stack. Moreover, it is convenient for users to identify the features of each card 310 from the front.

[0062] Referring again to Figure 8, in order to enable the card arm 210 to automatically reset, the card ejector 200 of this embodiment further includes a reset element 240, which is configured to reset the card arm 210 from the released position to the retracted position. After the card arm 210 releases the card stack 300, the card stack 300 maintains a stable state with the housing 100 under the action of the first friction element 410 inside the housing 100. It is not necessary for the card arm 210 to continuously apply force to the card stack 300. Therefore, the card arm 210 is reset to the retracted position by the reset element 240, which facilitates the user to actuate the card ejector 200 next time. In this embodiment, the reset element 240 is connected between the housing 100 and the locking arm 210. The reset element 240 can be a torsion spring, which is sleeved on the first rotating shaft 213 of the locking arm 210, and the two torsion arms of the torsion spring are respectively connected to the bottom wall 114 and the locking arm 210; or the torsion spring is installed on the bottom wall 114, and the two torsion arms of the torsion spring are respectively connected to the bottom wall 114 and the locking arm 210 (as shown in Figure 4). As an alternative embodiment, the reset element 240 can also be a spring, with the two ends of the spring connected to the locking arm 210 and the housing 100 (as shown in Figure 14).

[0063] Referring again to Figures 5 and 8, the card holder of this embodiment includes a housing 100, a card ejector 200, and a constraint feature 500. The housing 100 has a receiving space 110 for accommodating a card stack 300 consisting of at least two cards 310 stacked together. The housing 100 includes a first main wall 150 and a second main wall 160, which are spaced apart along the thickness direction of the cards 310. The first main wall 150 and the second main wall 160 are located on opposite sides of the housing 100, and the distance between the first main wall 150 and the second main wall 160 determines the maximum thickness of the card stack 300, i.e., the maximum number of cards 310 that the housing 100 can hold. Therefore, the first main wall 150 can be understood as the front wall of the housing 100, and the second main wall 160 can be understood as the rear wall of the housing 100, as will be understood below.

[0064] Referring again to Figure 6, in this embodiment, the housing 100 further includes a frame 170 connected between the first main wall 150 and the second main wall 160. The frame 170 is generally U-shaped and can be formed by splicing or arranging multiple structural segments, such as two L-shaped segments, or by a single continuous structure. The frame 170 is connected to the left, bottom, and right sides of the first main wall 150 and the second main wall 160, forming the left side wall 115, bottom wall 114, and right side wall 116 of the housing 100. The frame 170 can be connected and fixed to the first main wall 150 and the second main wall 160 by fasteners such as screws and rivets, or by magnetic attraction, interference fit, or integral molding. As an alternative embodiment, the frame 170 can also be connected only to the left and right sides of the first main wall 150 and the second main wall 160, and the bottom wall 114 of the housing 100 can be formed by other structures, such as a card ejector 200. The frame 170, the first main wall 150, and the second main wall 160 are connected by screws, rivets, etc., or are integrally formed into a rigid whole. As an alternative embodiment, the frame 170 can also be connected to one side of the first main wall 150 and the second main wall 160, such as the left or right side, while the other side can be used to house parts of the card ejector 200, such as the operating arm 231. As another alternative embodiment, the frame 170 can also be configured to wrap around the outside of the first main wall 150 and the second main wall 160. The frame 170, the first main wall 150, and the second main wall 160 can be integrally formed; the frame 170, the first main wall 150, and the second main wall 160 can also be joined using splicing techniques, such as snap-fitting or bonding. The frame 170, the first main wall 150, and the second main wall 160 can be made of different materials to adapt to different usage requirements.

[0065] The constraint feature 500 is disposed within the receiving space 110. The constraint feature 500 is used to apply frictional force to the card 310, or to block and guide the card 310, or a combination of both. To achieve effective constraint on the card stack 300, the constraint feature 500 can be a single component, or a collection of two, three, or more components. For example, the constraint feature 500 can be disposed on at least one of the inner side of the frame 170, the inner side of the first main wall 150, or the inner side of the second main wall 160.

[0066] The card ejector 200 includes a card arm 210 and a first actuator 230. The first actuator 230 is for manual operation by the user and is kinetically connected to the card arm 210 to control the movement of the card arm 210. The card arm 210 can be directly driven by the first actuator 230, i.e., the first actuator 230 and the card arm 210 are rigidly connected; the card arm 210 can also be indirectly driven by the first actuator 230, i.e., the first actuator 230 is connected to the card arm 210 through a connecting rod or other connecting member. For ease of user operation, part of the structure of the first actuator 230 is located on the outside of the housing 100. The card arm 210 is located within the receiving space 110 and has a card ejection feature 220. The card ejection feature 220 is used to engage with the card 310 and, during the rotation of the card arm 210, drives the card stack 300 to be released outside the housing 100. The description of the card ejection feature 220 can be understood by referring to the aforementioned embodiments. To avoid repetition, it will not be repeated here.

[0067] Card arm 210 is configured to switch from a retracted position to a released position under the drive of the first actuator 230, causing the card stack 300 to move under the action of card ejection feature 220 and constraint feature 500, rotating and offsetting the stacked cards 310 in two mutually perpendicular directions, and releasing a portion of the cards 310 to the outside of the housing 100. It can be understood that another portion of the cards 310 is confined within the housing 100 due to the action of constraint feature 500, allowing the cards 310 to maintain a relatively stable support state with the housing 100, and preventing the cards 310 from easily detaching from the housing 100. In this embodiment, under the combined action of card ejection feature 220 and constraint feature 500, each card 310 in the card stack 300 rotates and offsets, for example, offsetting longitudinally and laterally, with multiple cards 310 stacked in a fan-shaped, dispersed manner. Therefore, the cards 310 located outside the housing 100 are offset laterally and vertically. After adjacent cards 310 are rotated and staggered in both the left-right and up-down directions, the overlapping area of ​​two stacked cards 310 is effectively reduced, resulting in a larger area of ​​card 310 exposed within the user's field of vision. This facilitates the user's quick identification of the required card 310. Furthermore, the larger exposed area of ​​the card 310 also makes it easier for the user to select the desired card 310 with their finger. It should be noted that non-adjacent cards 310 can also be configured to overlap in the front-back direction, as long as it does not affect the user's ability to identify the card 310.

[0068] Referring to Figure 6, in this embodiment, the constraint feature 500 is disposed within the U-shaped frame 170, and the card arm 210 is located on one side near the bottom wall 114 of the frame 170. The constraint feature 500 is used to apply frictional force to the card stack 300 from at least one side laterally, thereby preventing the card stack 300 from falling out of the housing 100. Moreover, the user will receive a certain damping force feedback when operating the first actuator 230. The constraint feature 500 can be disposed on the left, right, or both sides inside the frame 170. The constraint feature 500 can increase the frictional force of the housing 100 on the card 310 in the left-right direction. The card 310 continuously receives appropriate frictional force during the entire rotation and release process, so that the card 310 will not easily fall out of the housing 100 during this period. In addition, the user will receive a certain damping force feedback when operating the first actuator 230, resulting in a better operating feel. When the card stack 300 rotates to the release state, the card 310 can also maintain a certain friction with the housing 100, and will not fall out of the housing 100 due to the inertial force of rotation or slide back into the housing 100 due to its own weight.

[0069] Referring to Figure 6, and aided by Figures 2 and 3, the constraint feature 500 of one embodiment of this application includes a first friction element 410. The first friction element 410 is disposed on at least one side of the frame 170 along the lateral direction, that is, the first friction element 410 can be disposed on the left, right, or both sides inside the frame 170. The material and installation method of the first friction element 410 can be understood with reference to the foregoing embodiments, and will not be repeated here. The first friction element 410 is configured to provide suitable friction force to the side of the card 310 during the release of the card stack 300, and to enable the released card stack 300 to be stably supported in a dispersed state on the housing 100 under the action of friction force. Therefore, the card 310 will not fall out of the housing 100 due to the force of the card arm 210 or slide back into the housing 100 due to its own weight, making it convenient for the user to identify and remove the card 310.

[0070] In this embodiment, the constraint feature 500 further includes the inner convex surface 121 of the first sidewall 120, the second abutment surface 131 of the second sidewall 130, and the first abutment surface 141 of the constraint member 140. When the card ejector 200 is actuated by the user, the card arm 210 is driven to rotate from the retracted position to the released position. During the process of the card arm 210 moving from the retracted position to the released position, the card ejection feature 220 of the card arm 210 drives the card 310 to rotate. During this process, the left side 315 of the card 310 abuts against the inner convex surface 121 and rotates under the support of the inner convex surface 121, causing the card 310 to rotate approximately to the left around the contact point between the left side 315 and the inner convex surface 121; the upper side 316 of the card 310 abuts against the first abutment surface 141 when the card 310 rotates, causing the card 310 to slide approximately along the left side; simultaneously, the lower right corner edge 313 of the card 310 abuts against the second abutment surface 131 when the card 310 rotates.

[0071] Under the combined action of the inner convex surface 121, the second abutment surface 131, and the first abutment surface 141, the upper left corner 311 of card 310 protrudes from the opening 112, and the upper right corner 312 protrudes from the card ejection slot 111. Furthermore, the different rotation angles and sliding distances of the various cards 310 in the card stack 300 result in a fan-shaped, dispersed stacking of multiple cards 310. Constrained by the inner convex surface 121 and the second abutment surface 131, card 310 continuously experiences appropriate friction throughout the rotation process. During release, card 310 will not easily fall out of the housing 100, and even in the released state, card 310 maintains a certain friction with the housing 100, preventing it from falling out of the housing 100 due to rotational inertia or sliding back into the housing 100 due to its own weight. Moreover, the user experiences a certain amount of damping force feedback when actuating the card ejector 200, resulting in a better operating feel. It should be noted that when the number of cards 310 in the receiving space 110 is close to the maximum capacity, due to the large number of cards 310, in order to ensure that all cards 310 are fan-shaped and dispersed in the released state, some cards 310 have a larger rotation angle, which may cause the lower right corner 313 of these cards 310 to detach from the second abutment surface 131. The description of the inner convex surface 121, the second abutment surface 131 and the first abutment surface 141 is understood with reference to the foregoing embodiments.

[0072] Figure 7 is a front view schematic diagram of another card holder after the front wall of the present application is hidden, where the card arm is in the retracted position and the card is in the released state for easy illustration. Referring to Figure 7, the card 310 is shown by dashed lines to show the inner structure of the rear wall. In order to solve the problem that the card 310 near the second main wall 160 has a large rotation angle, especially the card 310 with the largest rotation angle, whose lower right corner 313 is detached from the housing 100, which may cause the card 310 to be detached from the housing 100, a third friction element 430 is provided on the inner side of the housing 100 in another embodiment of the present application. In the direction from the first main wall 150 to the second main wall 160, the rotation angle of the subsequent card 310 in the card stack 300 in the released state is larger than that of the previous card 310. The third friction element 430 is located on the inner side of the second main wall 160, so the third friction element 430 can abut against the card 310 with the largest rotation angle in the card stack 300.

[0073] The third friction element 430 is located longitudinally on the side of the second main wall 160 near the outlet 111, meaning the geometric center of the third friction element 430 is located in the upper half of the second main wall 160 along the longitudinal direction. Alternatively, the third friction element 430 is located longitudinally in the middle of the second main wall 160, meaning the geometric center of the third friction element 430 is located near the longitudinal centerline, specifically between one-third and two-thirds of the length of the second main wall 160 along the longitudinal direction. Laterally, the third friction element 430 is located on the side of the second main wall 160 near the opening 112 (i.e., near the inner convex surface 121), meaning the geometric center of the third friction element 430 is located in the left half of the second main wall 160.

[0074] When the card stack 300 is in the released state, the third friction element 430 abuts against the middle part of the card 310 with the largest rotation angle along its length direction near the inner convex surface 121, that is, the geometric center of the third friction element 430 abuts against the left half of the card 310 along its length direction and between one-third and two-thirds of the card 310 along its width direction; as an alternative embodiment, the third friction element 430 abuts against the side of the card 310 with the largest rotation angle near the lower left corner edge 314, that is, the geometric center of the third friction element 430 abuts against the lower left region of the card 310 (that is, the region near the lower left corner edge 314 among the four regions divided by the center line along its length direction and the center line along its width direction).

[0075] Therefore, the third friction element 430 abuts against the last card 310 in the card stack 300 (i.e., the card 310 closest to the second main wall 160) and applies friction to the card 310, thereby increasing the friction between a portion of the card 310 and the housing 100, while keeping the friction between the other portions of the card 310 and the housing 100 essentially unchanged. This effectively prevents the card 310 with the largest rotation angle in the fan-shaped card dispensing process from automatically detaching from the housing 100 during the release state. At the same time, the installation position of the third friction element 430 also ensures that the card 310 can be easily removed from the housing 100 by the user.

[0076] The third friction element 430 is made of materials such as rubber or silicone. The third friction element 430 is sheet-shaped, which can increase the friction area and thus increase the friction force. Moreover, it can reduce the thickness of the third friction element 430, thereby reducing the impact on the maximum number of cards 310 that can be stored inside the housing 100.

[0077] To further reduce the impact on the receiving space 110, in this embodiment, the inner side of the second main wall 160 of the card holder is provided with a third groove 161, and the third friction element 430 is installed in the third groove 161. The third friction element 430 can be installed by means of bonding, interference fit, etc.

[0078] Understandably, the third friction element 430 includes a base plate 431 and a protruding structure 432 disposed on the surface of the base plate 431. The base plate 431 is accommodated within the third groove 161, and the protruding structure 432 is located within the receiving space 110. For example, the protruding structure 432 can be a dot, a strip, or a bump. The base plate 431 can increase the adhesion of the third friction element 430, and the protruding structure 432 can increase the friction. The matching design of the third groove 161 and the base plate 431 can further reduce the occupation of the third friction element 430 in the receiving space 110 along the thickness direction of the card 310, and reduce the impact of the third friction element 430 on the maximum number of cards 310 that can be stored inside the housing 100.

[0079] Referring to Figures 14 and 15, another embodiment of the constraint feature 500 of this application includes a second friction element 420. This second friction element 420 is disposed on the inner side of the first main wall 150, or on the inner side of the second main wall 160, or simultaneously on the inner sides of both the first main wall 150 and the second main wall 160. The second friction element 420 applies frictional force along the thickness direction of the card stack 300. The second friction element 420 increases the frictional force between the housing 100 and the card stack 300, and between the cards 310 of the card stack 300, along the thickness direction of the card stack 300, thereby increasing the frictional force between the cards 310. The second friction element 420 can be made of materials such as felt, silicone, or rubber, or it can be a spring or a snap-fit ​​structure. The second friction element 420 provides appropriate friction to the card 310 during the release process of the card stack 300, and enables the released card stack 300 to be stably supported in the housing 100 under the action of friction. Therefore, the card 310 will not fall out of the housing 100 due to the force of the card arm 210 or slide back into the housing 100 due to its own weight when it is released, making it convenient for the user to identify and remove the card 310.

[0080] Referring to Figure 5, at least one of the first main wall 150 and the second main wall 160 has a finger notch 118 on the side near the card dispensing slot 111, and the finger notch 118 communicates with the receiving space 110. The finger notch 118 is preferably located on the main wall near the card 310 with the smallest rotation angle. The finger notch 118 helps the user to take out the card 310 with the smallest rotation angle from the card stack 300, that is, the card 310 with the smallest exposed area, which is generally the first card 310 facing forward in Figure 5.

[0081] Referring to Figure 6, and aided by Figures 2 and 3, another embodiment of the card holder of this application includes a housing 100 and a card ejector 200. The housing 100 has a receiving space 110 for accommodating a card stack 300 consisting of at least two cards 310 stacked together. The housing 100 includes a first sidewall 120 and a second sidewall 130 arranged laterally at intervals, located on opposite sides within the receiving space 110, respectively adjacent to the card stack 300. The first sidewall 120 has an inwardly convex surface 121, and the second sidewall 130 has a second abutment surface 131. The card ejector 200 includes a card arm 210 and a first actuator 230. The first actuator 230 is located outside the receiving space 110, and the card arm 210 is located inside the receiving space 110. The card arm 210 is configured to move between a retracted position and a released position under the actuation of the first actuator 230. The card arm 210 has a card ejection feature 220, which is configured to guide the card stack 300 to abut against the side of the first sidewall 120 and rotate around the inner convex surface 121 during the process of the card arm 210 moving from the retracted position to the released position, and to cause the card stack 300 to abut against the second abutment surface 131 near the corner of the second sidewall 130, thereby forcing a portion of the card stack 300 to be released to the outside of the housing 100 in a fan-shaped dispersion manner.

[0082] Referring to Figure 6, and aided by Figures 2 and 3, another embodiment of the card holder of this application includes a housing 100 and a card ejector 200.

[0088] Figure 13 is a structural schematic diagram of a card holder according to another embodiment of this application. Figure 14 is a front view schematic diagram of the card holder in the embodiment shown in Figure 13 with the sliding plate and front wall hidden. Referring to Figures 13 and 14, the card holder according to another embodiment of this application includes a housing 100, a card arm 210, and a second actuator 250. The structures of the housing 100 and the card arm 210 are similar to those in the previous embodiment and can be understood by reference. To avoid repetition, they will not be described again here. The difference in this embodiment is that the second actuator 250 includes a sliding plate 251. The sliding plate 251 is located outside the housing 100 and is rotatably connected to the housing 100. The sliding plate 251 is configured to drive the card arm 210 to rotate from the retracted position to the released position when rotated. For example, the slide 251 is connected to the housing 100 via the second pivot 2511. When the user operates the slide 251 to rotate and slide upward, the card ejection feature 220 of the card arm 210 drives the card stack 300 to rotate and be released into the housing 100 in a dispersed state. As an alternative embodiment, the slide 251 can also be configured such that when it rotates and slides downward, the card stack 300 is driven to rotate and be released into the housing 100 in a dispersed state.

[0089] Figure 15 is a top view of the card holder according to the embodiment shown in Figure 13, in which the slide is disassembled. Figure 16 is a structural diagram of the card holder according to the embodiment shown in Figure 13 after the slide is hidden. Referring to Figures 15 and 16, in this embodiment, the housing 100 includes a first main wall 150 located at the front end, and the slide 251 is located outside the first main wall 150. The first main wall 150 is provided with a first through groove 151 for limiting the movement path of the slide 251. The first through groove 151 can extend longitudinally or arcuately.

In this embodiment, the constraint member 140 has two concave cavities 142, and a portion of the sidewalls of the cavities 142 are configured as arc-shaped contact walls 1421. A protruding turntable 143 is formed between the two concave cavities 142. The surface of the turntable 143 is smoothly transitioned and serves as a rotational fulcrum for the card stack 300 to be released in a fan-shaped manner. The card stack 300 rotates around the turntable 143 under the drive of the card ejection feature 220 of the card arm 210 and is constrained by the contact wall 1421, thereby forming a fan-shaped dispersion release state. The contact wall 1421 can also apply frictional force to the cards 310 in the released state, so that the card stack 300 can be stably supported on the housing 100.

The difference in this embodiment is that the third actuator 260 includes a push button 261, which is configured to slide on the surface of the first main wall 150 of the housing 100 to drive the card arm 210 to rotate from the retracted position to the released position. For example, push button 261 is connected to card arm 210. When the user slides push button 261 upward, card ejection feature 220 of card arm 210 drives card stack 300 to rotate and be released into the housing 100 in a dispersed state. As an alternative embodiment, push button 261 can also be configured so that when it slides downward, card stack 300 is driven to rotate and be released into the housing 100 in a dispersed state.
