Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, specifically relating to a card holder and an electronic device. Background Technology

[0002] Mobile phones and other electronic devices have card slots for inserting SIM cards and other cards. In related technologies, these slots typically have a SIM card ejector pin hole. To remove the card, a SIM card ejector pin is inserted into this hole to pop out the card. However, because SIM card ejector pins are relatively small, inconvenient to carry, and easily lost, users often find themselves without a SIM card ejector pin when they need to remove the card, causing significant inconvenience. Summary of the Invention

[0003] The purpose of this application is to provide a card holder and an electronic device to solve the problem that current card holders require the use of card pins for disassembly, which causes great inconvenience to users in the process of disassembling the card holder.

[0004] In a first aspect, embodiments of this application provide a card holder, which includes a card tray and a base, wherein... The card tray includes a tray body with a card slot for receiving cards. The base includes a base body and an elastic reset member. The base body has a receiving cavity. The tray body is detachably mounted to the receiving cavity through the opening side of the receiving cavity along a first direction. At least a portion of the elastic reset member is located within the receiving cavity. One of the card tray and the base also includes a first limiting structure, and the other of the card tray and the base also includes a second limiting structure. When the card holder is in the first state, the card tray is installed in the receiving cavity, the tray body abuts against the elastic reset member, causing the elastic reset member to deform, and the first limiting structure and the second limiting structure cooperate to limit the card holder from switching from the first state to the second state; pressing the tray body from the opening side of the receiving cavity along the first direction releases the limiting of the first limiting structure and the second limiting structure, so that the card holder switches from the first state to the second state; when the card holder is in the second state, the elastic reset member resets and can push the tray body out of the receiving cavity along the first direction.

[0005] Secondly, embodiments of this application disclose an electronic device, which includes a device body and the aforementioned card holder, wherein the base of the card holder is mounted on the device body.

[0006] This application discloses a card holder that can be applied to electronic devices. The card holder has a card slot for accommodating cards, and a receiving cavity for accommodating the card holder. The card holder can be detachably installed in the receiving cavity. Furthermore, the receiving body includes an elastic reset member, at least a portion of which is located within the receiving cavity.

[0007] To ensure controllability of the locking relationship between the card tray and the base, the card tray disclosed in this application includes a first limiting structure for one of the card tray and the base, and a second limiting structure for the other. When the card tray is in the first state, the card tray is installed in the receiving cavity, and the card tray body abuts against the elastic reset member, causing the elastic reset member to deform. The first limiting structure and the second limiting structure cooperate to limit the card tray from switching from the first state to the second state. Pressing the card tray body along the first direction from the opening side of the receiving cavity releases the limiting of the first and second limiting structures, allowing the card tray to switch from the first state to the second state. When the card tray is in the second state, the elastic reset member resets and can push the card tray body out of the receiving cavity along the first direction.

[0008] Obviously, in the use of the card holder disclosed in the embodiments of this application, the process of assembling and disassembling the card tray does not require the use of a card pin, which makes the card holder disclosed in the embodiments of this application relatively convenient to use.

Detailed Implementation

[0011] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0012] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0013] like Figures 1-8 As shown in the figure, this application discloses a card holder that can be applied to electronic devices. The card holder can accommodate cards such as SIM cards to ensure that the cards can be stably installed inside the electronic devices.

[0014] In order to ensure that the card can be installed in and removed from the electronic device, the card holder disclosed in this application needs to have the ability to form a detachable connection with the device body of the electronic device. At the same time, when the card holder is installed in the device body, any part of the card holder needs to be able to form a reliable relative fixed relationship with the device body.

[0015] Based on the above situation, such as Figure 1 , Figure 2 and Figure 4As shown in the embodiments of this application, the card holder includes a card tray 100 and a base 200. To ensure a waterproof connection, a sealing ring is typically provided between the card tray 100 and the base 200. The base 200 is typically fixedly installed within the electronic device body, and by creating a detachable assembly relationship between the card tray 100 and the base 200, the card mounted on the card tray 100 can be removed from the electronic device.

[0016] In detail, such as Figure 2 and Figure 3 As shown, the card holder 100 includes a holder body 110, on which cards can be mounted. Therefore, in this application, as... Figure 2 As shown, the card holder body 110 is provided with a card slot 111 for accommodating cards. The shape and size of the card slot 111 can be determined based on parameters such as the shape and size of the cards to be installed, ensuring that the cards can be properly installed within the card slot 111. Furthermore, in this application, one or two cards can be installed in the card slot 111, or more cards can be installed in the card slot 111, or the number of card slots 111 can be one or more, enabling the card holder to accommodate multiple cards. This application does not limit the scope of the application.

[0017] At the same time, such as Figure 4 As shown, the seat 200 includes a seat body 210, and, as Figure 4 As shown, the base body 210 has a receiving cavity, and the tray body 110 can be detachably installed in the receiving cavity through the opening side of the receiving cavity along a first direction. During the assembly of the electronic device, the base body 210 can typically be fixedly installed within the device body, and at least one of the base body 210 and the tray body 110 can also form an electrical connection with the device body. This ensures that after the card is installed in the tray body 110 and the tray body 110 is installed in the receiving cavity of the base body 210, an electrical connection between the card and the device body can be maintained. Specifically, the shape and size of the receiving cavity can be designed based on the shape and size of the card tray 100, and the opening of the receiving cavity is located on the side of the electronic device body to ensure that the card tray 100 can be installed and removed from the receiving cavity through the opening.

[0018] To reduce the difficulty of removing the cassette 100 from its self-accepting cavity, in the embodiments of this application, such as Figure 4As shown, the seat body 200 may also include an elastic reset member 230, and in the first direction, the elastic reset member 230 is sandwiched between the support body 110 and the seat body 210. More specifically, at least a portion of the elastic reset member 230 is located within the receiving cavity. It should be noted that, in this application, "the elastic reset member 230 is sandwiched between the support body 110 and the seat body 210" means that at least a portion of the elastic reset member 230 is located between the cavity opening and the cavity bottom of the receiving cavity of the seat body 210, and at least a portion of the support body 110 is located on the side of the elastic reset member 230 opposite to the cavity bottom of the seat body 210.

[0019] Of course, in this application, the dimensions and installation position of the elastic reset member 230 also need to be designed so that when the card holder 100 is locked in the receiving cavity of the seat body 200, the elastic reset member 230 can be in an elastic state. For example, the elastic reset member 230 can be in a compressed state, so that after the locking relationship between the card holder 100 and the receiving cavity of the seat body 210 is released, the elastic reset member 230 can release the elastic force and drive the card holder 100 to pop out of the receiving cavity, thereby greatly reducing the difficulty of disassembling the card holder 100. Of course, in other embodiments of this application, the installation position and assembly method of the elastic reset member 230 can also be changed, and when the card holder 100 is locked in the receiving cavity of the seat body 200, the elastic reset member 230 can be in a stretched state. Specifically, the elastic reset member 230 can be a compression (or tension) spring.

[0020] In one specific embodiment of this application, the elastic reset member 230 can be installed around the card holder 100, and one end of the elastic reset member 230 is fixed in the middle of the receiving cavity along the first direction. In this case, by providing a blocking structure at the other end of the elastic reset member 230, the card holder 100 can be blocked by the blocking structure during the installation of the card holder 100 into the receiving cavity. Then, as the card holder 100 continues to move into the receiving cavity, the card holder 100 can stretch the elastic reset member 230. Accordingly, after the locking state of the card holder 100 is released, the card holder 100 can be driven to pop out of the receiving cavity under the action of the elastic reset member 230.

[0021] To reduce the installation difficulty of the elastic reset member 230 and minimize the space occupied by the card holder 100 (i.e., the entire card seat) in the third direction, in another embodiment of this application, the elastic reset member 230 can be located at the end of the card holder 100, that is, the elastic reset member 230 is sandwiched between the tail of the card holder 100 and the bottom of the cavity of the seat 200. Accordingly, as the card holder 100 gradually extends into the receiving cavity, the card holder 100 and the seat 200 will compress the elastic reset member 230, and when the card holder 100 is in the locked state, the elastic reset member 230 is in a compressed state.

[0022] As described above, the elastic reset member 230 can be installed at the tail of the card tray 100. In another embodiment of this application, the elastic reset member 230 can also be located on the bottom side of the cavity of the seat body 210 away from the opening side, that is, the elastic reset member 230 is located at the bottom of the receiving cavity. This makes the structure on the card tray 100 relatively less and prevents the elastic reset member 230 from hooking with the user's hand or clothing when the card tray 100 is removed and the card is installed. This can further improve the user experience.

[0023] As described above, the elastic reset member 230 can be a spring or other device. In order to prevent the elastic reset member 230 from being damaged due to twisting and deformation when the card holder 100 is installed, in another embodiment of this application, the elastic reset member 230 can be a spring sheet, which can improve the reliability of the elastic reset member 230.

[0024] In order to further improve the overall effect of the elastic reset member 230, in a further embodiment of this application, the elastic reset member 230 may include multiple spring pieces, and the multiple spring pieces may be distributed at intervals in a third direction. This allows the card holder 100 to form a good elastic fit with the spring pieces at different positions in the aforementioned direction, so as to prevent the card holder 100 from being deflected and stuck when it is acted upon by the elastic reset member 230.

[0025] In one specific embodiment of this application, the number of spring pieces 231 can be two, with the two spring pieces 231 spaced apart in a third direction and their openings facing each other. In this case, the processing and assembly difficulty of the elastic reset member 230, as well as the overall elastic effect of the elastic reset member 230, can be balanced, preventing the card holder 100 from becoming stuck due to skewness caused by the elastic force during ejection. The third direction intersects with the first direction. More intuitively, the third direction is... Figure 4 in the direction Y.

[0026] Based on the above-described structure of the card holder, in order to controllably lock the card tray 100 within the receiving cavity and controllably remove the card tray 100 from the receiving cavity, in this embodiment, one of the card tray 100 and the seat 200 further includes a first limiting structure 120, and the other of the card tray 100 and the seat 200 further includes a second limiting structure 220, so as to utilize the first limiting structure 120 and the second limiting structure 220 to control the locking state between the card tray body 110 and the seat body 210, wherein, in the card tray body When the 110 is locked to the seat body 210, the card holder is considered to be in the first state. Correspondingly, when the 110 is not locked to the seat body 210, the card holder is considered to be in the second state. Therefore, from the time the 110 is installed in the receiving cavity of the seat body 210 until the 110 is locked to the seat body 210, and from the time the 110 is unlocked to the time the 110 is removed from the receiving cavity, the card holder is considered to be in the second state.

[0027] In the first state, the card holder 100 is installed in the receiving cavity. The card holder body 110 of the card holder 100 abuts against the elastic reset member 230, causing the elastic reset member 230 to deform. At the same time, in the first state, the first limiting structure 120 and the second limiting structure 220 cooperate to limit the card holder from switching from the first state to the second state.

[0028] Obviously, when the card holder is in the first state, the cooperation between the first limiting structure 120 and the second limiting structure 220 can be used to lock and fix the holder body 110 in the receiving cavity of the seat body 210. And when the holder body 110 is not subjected to other external forces, it is ensured that the holder body 110 will not move further into the receiving cavity or towards the opening side of the receiving cavity.

[0029] Accordingly, when it is necessary to release the aforementioned locking state of the tray body 110, the tray body 110 of the card holder 100 can be pressed from the opening side of the receiving cavity along the first direction to release the limiting structure 120 and the second limiting structure 220, so that the card holder switches from the first state to the second state. Here, the first direction is the axial direction of the opening of the receiving cavity, or in other words, the first direction is the depth direction of the receiving cavity.

[0030] As described above, during the process of the tray body 110 being installed in the receiving cavity along the first direction from the opening side of the receiving cavity to switch to the first state, the tray body 110 of the card holder 100 can abut against the elastic reset member 230 and cause the elastic reset member 230 to deform. In the aforementioned process, the elastic reset member 230 accumulates elastic potential energy. Thus, after the locking state between the tray body 110 and the seat body 210 is released (i.e., when the card holder is in the second state), the elastic reset member 230 resets and can push the tray body 110 out of the receiving cavity along the first direction.

[0031] In one specific embodiment of this application, both the first limiting structure 120 and the second limiting structure 220 can be magnets, and at least one of them can be an electromagnet. Thus, when the card holder is in the first state, the first limiting structure 120 and the second limiting structure 220 are magnetically attracted to each other, and when the card holder is in the second state, the first limiting structure 120 and the second limiting structure 220 are magnetically repelled. Of course, in this case, the interaction direction between the first limiting structure 120 and the second limiting structure 220 needs to include a component parallel to the first direction.

[0032] This application discloses a card holder that can be applied to electronic devices. In the card tray 100, the tray body 110 has a card slot 111 for accommodating cards, and the base body 210 has a receiving cavity for accommodating the tray body 110. The tray body 110, on which the card is mounted, can be detachably mounted in the receiving cavity. Furthermore, the base body 200 also includes an elastic reset member 230, at least a portion of which is located within the receiving cavity.

[0033] To ensure controllability of the locking relationship between the card tray 100 and the seat 200, the card holder disclosed in this application includes a first limiting structure 120 for the card tray 100 and a second limiting structure 220 for the seat 200. When the card holder is in the first state, the card tray 100 is installed in the receiving cavity, and the card holder body 110 abuts against the elastic reset member 230, causing the elastic reset member 230 to deform. The first limiting structure 120 and the second limiting structure 220 cooperate to limit the card holder from switching from the first state to the second state. Pressing the card holder body 110 along the first direction from the opening side of the receiving cavity releases the limiting of the first limiting structure 120 and the second limiting structure 220, causing the card holder to switch from the first state to the second state. When the card holder is in the second state, the elastic reset member 230 resets and can push the card holder body 110 out of the receiving cavity along the first direction.

[0034] Obviously, in the process of using the card holder disclosed in the embodiments of this application, the process of assembling and disassembling the card tray 100 does not require the use of a card pin, which makes the card holder disclosed in the embodiments of this application relatively convenient to use.

[0035] To reduce the control difficulty of the first limiting structure 120 and the second limiting structure 220, in another embodiment of this application, the second limiting structure 220 may include a guide section 221 and a blocking section 222. During the process of the card holder 100 being installed into the receiving cavity from the opening side of the receiving cavity, the guide section 221 is used to guide the first limiting structure 120 to the blocking section 222. Correspondingly, when the first limiting structure 120 moves along the guide section 221 and the first limiting structure 120 cooperates with the blocking section 222, the blocking effect of the blocking section 222 can be used to switch the first limiting structure 120 and the second limiting structure 220 to a locked state.

[0036] That is, when the card holder is in the first state, the first limiting structure 120 is located in the blocking section 222 and cooperates with the blocking section 222 so that the first limiting structure 120 cooperates with the second limiting structure 220 to limit the movement of the tray body 110 in the first direction toward the opening side close to the receiving cavity.

[0037] Correspondingly, when it is necessary to release the locking state of the first limiting structure 120 and the second limiting structure 220, the first limiting structure 120 can be disengaged from the blocking section 222 by applying an external force to the holder body 110 and moving the holder body 110 further into the depth of the receiving cavity, thereby putting the card holder into the second state.

[0038] That is, when the card holder is in the second state, the first limiting structure 120 disengages from the blocking section 222 to release the cooperation between the first limiting structure 120 and the second limiting structure 220.

[0039] Specifically, in order to ensure that the guide segment 221 has guiding capability, in this application, at least a portion of the guide segment 221 is in an inclined extension state. Correspondingly, the blocking segment 222 is located at one end of the guide segment 221 and can cooperate with the blocking segment 222 after the first limiting structure 120 moves along the guide segment 221.

[0040] More specifically, in order to reduce the assembly difficulty of the first limiting structure 120 and the second limiting structure 220, in a specific embodiment of this application, the card holder 100 may include the first limiting structure 120, and the seat 200 may include the second limiting structure 220, that is, as shown... Figure 2 As shown, the first limiting structure 120 is installed on the support body 110, and as... Figure 4 As shown, the second limiting structure 220 is installed on the seat body 210.

[0041] As described above, the second limiting structure 220 may include the guide section 221 and the blocking section 222, and the guide section 221 is inclined relative to the second direction. Based on this, in this application, the first limiting structure 120 includes a limiting post 121 and an elastic driving member 122, so as to utilize the elastic driving member to provide a driving action for the limiting post 121, ensuring good fit stability between the limiting post 121 and the second limiting structure 220. Wherein, as... Figure 3 As shown, the limiting post 121 and the support body 110 are movably engaged in the second direction, and the elastic driving member 122 is elastically connected between the limiting post 121 and the support body 110 in the second direction, wherein the first direction and the second direction intersect. Furthermore, in the above embodiment, the elastic reset member 230 may include spring pieces 231 distributed along a third direction. Based on this, the third direction can be made to intersect the plane containing the first direction and the second direction; in other words, there is no parallel relationship between any two of the first direction, the second direction, and the third direction.

[0042] When the first limiting structure 120 and the second limiting structure 220 respectively adopt the above-described structures, such as Figure 6 As shown, during the process of inserting the card holder 100 into the receiving cavity along the first direction, the limiting post 121 moves along the guide section 221, and causes the elastic drive member 122 and the elastic reset member 230 to deform. The guide section 221 is used to guide the limiting post 121 to the blocking section 222, and under the restoring force of the elastic drive member 122, the limiting post 121 is separated from the guide section 221, and the limiting post 121 and the blocking section 222 cooperate to limit the card holder, so that the card holder switches from the second state to the first state, thereby achieving the purpose of locking the card holder 100 and the seat 200 together.

[0043] In order to ensure that the blocking section 222 can provide a locking effect for the limiting post 121 and restrict the movement of the tray body 110 along the first direction toward the opening side of the receiving cavity, more specifically, when the card holder is in the first state, the blocking section 222 blocks the limiting post 121 from moving along the first direction toward the opening side of the receiving cavity, so that the first limiting structure 120 and the second limiting structure 220 cooperate to limit the movement.

[0044] Accordingly, in order to release the locking relationship between the limiting post 121 and the blocking section 222, such as Figure 8 As shown, by continuing to press the card holder 100 along the first direction from the opening side of the receiving cavity, the limiting post 121 can be disengaged from the blocking section 222, thereby releasing the cooperation and limiting between the first limiting structure 120 and the second limiting structure 220, and switching the card holder from the first state to the second state.

[0045] That is, in this application, the first limiting structure 120 is a device in the card holder 100 that cooperates with the second limiting structure 220 of the base 200, so that the card holder 100 and the base 200 can form a detachable relationship. Specifically, in this application, the elastic drive member 122 is used to enable the limiting post 121 and the holder body 110 to move and cooperate in the second direction, so that the position of the limiting post 121 relative to the holder body 110 in the second direction can be changed, and thus the cooperation state between the holder body 110 and the base 200 is changed by cooperating to change the position of the limiting post 121 in the first direction.

[0046] Specifically, by means of welding or bonding, one end of the elastic drive member 122 can be directly or indirectly fixedly connected to the limiting post 121, and the other end of the elastic drive member 122 can be fixedly connected to the support body 110, so as to ensure that the elastic drive member 122 can provide elastic thrust and elastic tension to the limiting post 121 by compression and extension respectively.

[0047] As described above, the first direction intersects with the second direction. That is, in this application, the second direction and the first direction are not parallel; they form an angle between them, which is greater than 0° and less than 180°. To reduce the structural design difficulty of the card tray 100 and the second limiting structure 220 in the card holder, in a further embodiment of this application, the first direction can be perpendicular to the second direction. More intuitively, the first direction can be... Figure 1 The direction X in the middle, and the second direction is Figure 2 The direction Z in the equation. Furthermore, both the first and second directions can be made perpendicular to the third direction.

[0048] As described above, during the movement of the limiting post 121 relative to the seat body 210 from the opening side of the receiving cavity along the first direction with the support body 110, the guide section 221 can provide guidance for the limiting post 121. Specifically, the guide section 221 can be a straight inclined extension structure, or the guide section 221 can also be a curved inclined extension structure. This article does not limit this.

[0049] During the movement of the limiting post 121 along the guide section 221, it can be assumed that the limiting post 121 is located on the side of the upper surface of the guide section 221. Based on this, the blocking section 222 can be located on the side of the lower surface of the guide section 221, and the blocking section 222 can have a bent structure, with the blocking section 222 facing the bottom of the receiving cavity, or in other words, the blocking section 222 is concave and bent towards the opening side of the receiving cavity. In this case, the second direction can have a first component parallel to the first direction, and the second direction can have a second component perpendicular to the first direction, and the direction of the aforementioned second component can be parallel to the overall thickness direction of the guide section 221.

[0050] In this case, the elastic drive member 122 can be connected to the end of the support body 110 facing the bottom of the receiving cavity. As the limiting post 121 moves along the guide section 221 into the receiving cavity, the elastic drive member 122 can be compressed. After the limiting post 121 moves to the bottom of the guide section 221 closest to the receiving cavity, the elastic drive member 122, in order to restore its own deformation, can drive the limiting post 121 towards the side where the lower surface of the guide section 221 is located, and drive the limiting post 121 towards the side closer to the opening of the receiving cavity, thereby limiting the... The positioning post 121 is driven into the blocking section 222. Under the combined action of the elastic drive member 122 and the blocking section 222, and when the card holder 100 is no longer subjected to other external forces, the positioning post 121 is blocked by the blocking section 222 and cannot continue to move towards the opening side of the receiving cavity, thereby ensuring that the card holder 100 will not come out of the receiving cavity. At the same time, the positioning post 121 is also blocked by the elastic drive member 122 and cannot continue to move towards the opening side away from the receiving cavity, thereby ensuring that the card holder 100 will not continue to move deeper into the receiving cavity.

[0051] Obviously, by adopting the above technical solution, a reliable locking relationship can be ensured between the card holder 100 and the seat 200. Correspondingly, when the card holder 100 is in the locked state, by continuing to apply force to the card holder 100, the card holder 100 can continue to move deeper into the receiving cavity along the first direction, thereby allowing the limiting post 121 to disengage from the blocking section 222. Under the action of the elastic drive member 122, the limiting post 121 moves in the direction away from the lower surface of the guide section 221 of the blocking section 222, thereby allowing the limiting post 121 to disengage from the blocking section 222. Under the action of the elastic reset member 230, it disengages from the receiving cavity, completing the disassembly of the card holder 100.

[0052] To reduce the overall design complexity of the second limiting structure 220, in another embodiment of this application, such as... Figure 5 As shown, in the first direction, the blocking segment 222 is located on the side of the guide segment 221 away from the opening side of the receiving cavity. More intuitively, the guide segment 221 is located between the opening side of the receiving cavity and the blocking segment 222, so that when the card holder 100 is gradually installed into the receiving cavity of the seat 200 from the opening side of the receiving cavity along the first direction, the limiting post 121 can gradually move along the guide segment 221, and when the limiting post 121 moves to the end of the guide segment 221, the limiting post 121 can engage with the blocking segment 222.

[0053] In this embodiment, to ensure that the blocking section 222 prevents the card holder 100 installed in the receiving cavity from separating again from the seat 200 when no other force is applied, in this application, as follows: Figure 5As shown, in the first direction, the blocking segment 222 is located between the first end of the guide segment 221 near the opening of the receiving cavity and the second end of the guide segment 221 away from the opening of the receiving cavity. Furthermore, in this application, by designing the structure and dimensions of the guide segment 221 and the blocking segment 222, the distance between the blocking segment 222 and the end of the elastic drive member 122 away from the limiting post 121 can be greater than the natural length of the elastic drive member 122. The first and second ends of the guide segment 221 can be respectively the first mating position 2211 and the second mating position 2212 of the guide segment 221, that is, as... Figure 5 As shown, the guide segment 221 has a first mating position 2211 and a second mating position 2212, and in a first direction, the first mating position 2211 is located between the opening side of the receiving cavity and the second mating position 2212.

[0054] As described above, the guide segment 221 is inclined relative to both the first and second directions, which causes a height difference between the two ends of the guide segment 221 in the second direction. Consequently, when the limiting post 121 engages with the two ends of the guide segment 221 (i.e., the first engagement position 2211 and the second engagement position 2212), the elastic state of the elastic drive member 122 is different. In other words, when the limiting post 121 engages with the first engagement position 2211 and the second engagement position 2212 of the guide segment 221, the length of the elastic drive member 122 is different.

[0055] More specifically, when the card holder is in the first state, the limiting post 121 is located in the blocking section 222, and the elastic drive member 122 has a first dimension in the second direction; when the card holder is in the second state, and the limiting post 121 is located in the first mating position 2211 of the guide section 221, the elastic drive member 122 has a second dimension in the second direction; when the card holder is in the second state, and the limiting post 121 is located in the second mating position 2212 of the guide section 221, the elastic drive member 122 has a third dimension in the second direction; wherein the second dimension is less than the natural length of the elastic drive member, and the second dimension is less than or equal to the first dimension, the first dimension is less than the third dimension, and the third dimension is greater than the natural length. More specifically, the second dimension can be smaller than the first dimension.

[0056] Based on the above design, in this application, by designing parameters such as the length of the elastic drive member 122 and the structure and position of the guide section 221 and the blocking section 222, the limiting post 121 can achieve the purpose of limiting and cooperating with the blocking section 222 under the action of the elastic drive member 122, thereby ensuring that the tray body 110 and the seat body 210 form a reliable fixed assembly relationship; at the same time, when it is necessary to separate the card tray 100, the elastic force of the elastic drive member 122 is overcome by external force, and the limiting post 121 is separated from the blocking section 222. Meanwhile, under the action of the elastic drive member 122, the limiting post 121 can move to the side of the second limiting structure 220 where the elastic drive member 122 is located, thereby making the limiting post 121 no longer restricted by the second limiting structure 220 in the first direction, and allowing the card tray 100 to be separated from the seat body 200.

[0057] To more intuitively illustrate the technical solution claimed in this application, the first direction can be considered as the front-back direction, and the second direction as the up-down direction. Based on this, in this application, when the card tray 100 needs to be installed, as follows... Figure 6 As shown, because the distance between the first mating position on the opening side of the guide section 221 near the receiving cavity and the end of the elastic drive member 122 away from the limiting post 121 is less than the natural length of the elastic drive member 122, when the card holder 100 is first installed in the receiving cavity, the limiting post 121 can be positioned above the first mating position of the guide section 221 under the action of the elastic drive member 122. As the card holder 100 continues to move inward toward the seat 200 along the first direction (the specific direction of movement is...), Figure 6 In the direction F), the limiting post 121 can move along the upper surface of the guide section 221, causing the elastic drive member 122 to be gradually stretched; simultaneously, as the card holder 100 gradually moves into the receiving cavity, when the limiting post 121 moves to a mating position on the side of the guide section 221 away from the opening of the receiving cavity, the elastic drive member 122 is in a stretched state, that is, at this time the length of the elastic drive member 122 is greater than its natural length. Furthermore, as the card holder 100 continues to move into the receiving cavity in the first direction, since the blocking section 222 is located below the guide section 221, further, as Figure 7 As shown, under the stretching action of the elastic drive member 122, the limiting post 121 can be pulled by the elastic drive member 122, and the limiting post 121 is disengaged from the guide section 221 and cooperates with the blocking section 222 so that the card holder 100 and the seat 200 form a locking relationship.

[0058] Without the application of other external forces, the aforementioned engagement between the limiting post 121 and the blocking section 222 will not be disrupted, thus ensuring a stable locking relationship between the support body 110 and the seat body 210. Of course, in order for the blocking section 222 to provide a limiting function for the limiting post 121 and prevent the support body 110 from detaching from the seat body 210, the design of the blocking section 222 must ensure that it provides a limiting function for the limiting post 121 in both the first and second directions.

[0059] For example, the blocking segment 222 can be an arc-shaped groove, with the upper surface of the blocking segment 222 concave and bent downward relative to the upper surface of the guide segment 221. In this case, under the pulling action of the elastic drive member 122 in the second direction, the blocking segment 222 can stably abut against the bottom of the aforementioned arc-shaped groove of the blocking segment 222, and the sidewall of the arc-shaped groove can provide a blocking effect for the limiting post 121 in the first direction to prevent the limiting post 121 from moving in the opposite direction relative to the seat 200 and disengaging from the receiving groove. Of course, in other embodiments of this application, the blocking segment 222 can also adopt other structural forms, which will not be described in detail here.

[0060] Based on the above structure, when it is necessary to disassemble the card tray 100, such as Figure 8 As shown, by applying a force to the cassette 100, the cassette 100 can be driven to continue moving along the first direction into the receiving cavity of the seat 200 (the specific direction of movement is...). Figure 6 The direction F in the middle is used to disengage the limiting post 121 from the blocking section 222. Correspondingly, after the limiting post 121 disengages from the blocking section 222, it is pulled in the second direction by the elastic drive member 122, so that the limiting post 121 can be pulled below the blocking section 222 and the guide section 221. This releases the locking relationship between the second limiting structure 220 and the limiting post 121, so that the limiting post 121 can move along the first direction with the card holder 100 to outside the receiving cavity.

[0061] Of course, in order to prevent the second limiting structure 220 from obstructing the process of the card holder 100 leaving the receiving cavity, in this application, the lower part of the blocking section 222 and the guide section 221 are in a through state along the first direction. That is, when the limiting post 121 is located below the second limiting structure 220 (that is, when the limiting post 121 and the elastic drive member 122 are both located on the same side of the second limiting structure 220), the blocking section 222 and the guide section 221 will not obstruct the movement of the limiting post 121 along the first direction.

[0062] Furthermore, when the limiting post 121 moves along the lower surface of the guide section 221 toward the opening of the receiving cavity, when the limiting post 121 moves to the second mating position 2212 of the guide section 221, the elastic drive member 122 is in a compressed state, thereby ensuring that no corresponding operation is required when the card holder 100 is installed next time, and the limiting post 121 can be located on the upper surface of the second mating position 2212 of the guide section 221, so as to facilitate the next installation of the card holder 100.

[0063] As described above, the blocking segment 222 can be an arc-shaped groove structure. To balance the positioning effect and ease of detachment of the blocking segment 222, in another embodiment of this application, such as... Figure 5 As shown, the blocking section 222 can also include a first sub-segment 2221 and a second sub-segment 2222, wherein the first sub-segment 2221 and the second sub-segment 2222 are bent relative to each other. The first sub-segment 2221 provides a limiting effect on the card holder 100 in a first direction, preventing the card holder 100 from uncontrollably detaching from the seat 200. Simultaneously, the second sub-segment 2222 provides a limiting effect on the limiting post 121 in a second direction, ensuring that the limiting post 121 can stably remain in a state engaged with the blocking section 222 when no other external force is applied. Accordingly, during the process of disassembling the card holder 100, a force can continue to be applied to the card holder 100, causing the card holder 100 to continue moving into the receiving cavity along the first direction until the limiting post 121 separates from the second sub-segment 2222.

[0064] That is, in this embodiment, when the card holder is in the first state, the first segment 2221 is limited along the first direction to the side of the limiting post 121 near the opening of the receiving cavity, so as to restrict the tray body 110 from moving along the first direction toward the opening of the receiving cavity. The second segment 2222 and the limiting post 121 are mutually limited in the second direction. At least one of the second segment 2222 and the elastic drive member 122 is used to restrict the tray body 110 from moving along the first direction toward the opening away from the receiving cavity.

[0065] Of course, in order to ensure that the first segment 2221 can limit the limiting post 121 in the first direction to prevent the card holder 100 from dislodging from the receiving cavity, the structure of the first segment 2221, especially its extension direction (or extension plane), needs to be designed. For example, the first segment 2221 can be a flat plate structure as a whole, and the first segment 2221 can extend obliquely from the second mating position of the guide segment 221 to the direction close to the first mating position of the guide segment 221. In the first direction, the end of the first segment 2221 away from the guide segment 221 is located between the two opposite ends of the guide segment 221.

[0066] To reduce the machining difficulty of the first segment 2221 and the installation difficulty of the card holder 100, in another embodiment of this application, the surface of the first segment 2221 can be perpendicular to the first direction. In this case, compared with the aforementioned embodiment, when the card holder 100 is installed in place, there will be no small-sized outward pushing action, which can also improve the installation accuracy of the card holder 100. The surface of the first segment 2221 is the surface of the first segment 2221 used to mate with the limiting post 121, and the aforementioned surface can be planar overall.

[0067] Similarly, the second segment 2222 can also be a flat inclined structure. In order to reduce the difficulty of disassembling the card holder 100, in another embodiment of this application, the surface of the second segment 2222 can be perpendicular to the second direction to ensure that the second segment 2222 can provide a reliable limiting effect for the limiting post 121 in the second direction, and reduce the difficulty of disassembling the card holder 100 during the disassembly process.

[0068] In the above embodiments, the second limiting structure 220 includes a guide section 221 and a blocking section 222. In order to ensure that the second limiting structure 220 can form a reliable fixed relationship with the seat body 210, a connecting structure can be provided between the guide section 221 and the seat body 210 by means of welding or the like. Of course, another connecting structure can also be provided between the blocking section 222 and the seat body 210.

[0069] To reduce the processing and assembly difficulty of the second limiting structure 220 and the seat body 210, in another embodiment of this application, the second limiting structure 220 may further include a connecting portion 223, thereby fixing the outer side of the second sub-segment 2222 to the bottom edge of the seat body 210 via the connecting portion 223. In this case, the second sub-segment 2222, the connecting portion 223, the seat body 210, and the guide segment 221 can be integrally formed, thereby reducing the processing and assembly difficulty of the entire card holder.

[0070] Specifically, by using sheet metal processing, the edges of the sheet metal are bent to form a base plate 210 that is perpendicular or substantially perpendicular to each other and other parts including the connecting part 223. Then, by further bending the part of the other part including the connecting part 223 that is far away from the base plate 210, the connecting part 223 and the blocking section 222 (and the guide section 221) that are perpendicular or substantially perpendicular to each other can be formed. Of course, by further bending and stretching the blocking section 222 (and the guide section 221), the blocking section 222 including the first sub-section 2221 and the second sub-section 2222, and the guide section 221 that is inclined relative to both the first and second directions can be formed.

[0071] In the above embodiments, the guide section 221 and the blocking section 222 can be interconnected. In order to further reduce the processing and assembly difficulty of the guide section 221, the blocking section 222, and the entire seat 200, in another embodiment of this application, the ends of the guide section 221 and the blocking section 222 that are close to each other can be separated. In this case, in order to further reduce the processing difficulty of the guide section 221.

[0072] Based on the above embodiments, the seat body 200 can also include another connecting structure similar to the connecting portion 223 for connecting the blocking section 222. The aforementioned connecting structure can be a second connecting portion 225. Referring to the processing of the blocking section 222, another part of the plate protruding structure is bent to form a portion including the aforementioned second connecting portion 225. Then, by bending the portion of the aforementioned second connecting portion 225 that is away from the seat body 210 again, the guide section 221 can be formed.

[0073] Considering that when the guide section 221 is directly connected to the seat body 210 through the second connecting part 225, the machining difficulty of the inclined guide section 221 may be relatively large, and it may have an adverse effect on the structural reliability of the second connecting part 225, therefore, in another embodiment of this application, such as Figure 4 and Figure 5 As shown, the guide section 221 and the blocking section 222 are separated at their close ends, and a portion of the blocking section 222 (such as the first sub-segment 2221 described above) is located on the side of the guide section 221 near the bottom plate of the seat body 210. Simultaneously, the second limiting structure 220 may include a straight section 224, wherein the straight section 224 is connected to one end of the guide section 221 near the opening of the receiving cavity, the straight section 224 extends along a first direction, and the outer side of the straight section 224 is fixedly connected to the bottom plate of the seat body 210 via a second connecting portion 225.

[0074] That is, in this application, the straight section 224 and the aforementioned second connecting portion 225 are basically perpendicular to each other. Correspondingly, the aforementioned second connecting portion 225 and the straight section 224 are also perpendicular to each other. This makes it relatively easier to process the straight section 224, the guide section 221, and the blocking section 222 (including the first sub-segment 2221 and the second sub-segment 2222) of the seat 200 using sheet metal or other processes, and can make the precision of the formed second limiting structure 220 relatively higher.

[0075] Alternatively, the end of the guide section 221 away from the opening of the receiving cavity can be directly connected to the blocking section 222. In another embodiment of this application, a second straight section 226 can also be provided at the end of the guide section 221 away from the opening of the receiving cavity, so that the second straight section 226 can be connected to the blocking section 222. In this case, by enabling the second straight section 226 to overlap the side of the first sub-segment 2221 of the blocking section 222 away from the base plate 211, the transfer reliability of the limiting post 121 between the two parts of the second limiting structure 220 is improved.

[0076] Of course, in the embodiments of this application, the guide section 221 and the straight section 224 provided on the side away from the opening of the receiving cavity are not provided with any other connection structure similar to the connecting part 223 between them and the seat body 210. In other words, in the second direction, the guide section 221 and the bottom plate 211 of the seat body 210 are spaced apart from each other, and there is no intermediate structure directly connecting them.

[0077] In one specific embodiment of this application, in a direction perpendicular to the first direction and the depth direction of the slot 111, a first limiting structure 120 and a second limiting structure 220 may be provided only on one side of the support body 110, so that the two cooperate with each other and the support body 110 and the seat body 210 can switch between different states. The direction perpendicular to the first direction and the depth direction of the slot 111 can be the aforementioned third direction.

[0078] To further improve the stability and reliability of the fit between the cassette 100 and the seat 200, in another embodiment of this application, such as Figure 4 As shown, in the third direction, the support body 110 can be provided with a first limiting structure 120 and a second limiting structure 220 on both opposite sides. Correspondingly, the two first limiting structures 120 and the two second limiting structures 220 are matched one-to-one.

[0079] As described above, the first limiting structure 120 is assembled on the support body 110, and the limiting post 121 of the first limiting structure 120 is movably engaged with the support body 110 in the second direction. Specifically, the two can form a sliding engagement relationship. The support body 110 may be provided with a sliding groove extending in the second direction, and by installing the end of the limiting post 121 in the sliding groove, the limiting post 121 and the support body 110 can form a sliding engagement relationship in the second direction. Correspondingly, by connecting the opposite ends of the elastic drive member 122 to the opposite ends of the sliding groove and the limiting post 121 respectively, the elastic drive member 122 can provide an elastic force to the limiting post 121 in the second direction.

[0080] To improve the structural stability of the card tray 100, especially the reliability of the elastic drive member 122, in a specific embodiment of this application, the card tray 100 may further include a guide post 123. The guide post 123 is fixed to the tray body 110 and extends along a second direction. During the assembly of the card tray 100, the elastic drive member 122 is sleeved on the guide post 123, thereby using the guide post 123 to provide guidance and limiting for the elastic drive member 122, preventing the elastic drive member 122 from bending and deforming during compression, thereby improving the reliability of the elastic drive member 122.

[0081] Of course, in this application, the limiting post 121 can be directly fixed to one end of the elastic drive member 122, and when the limiting post 121 cooperates with the second limiting structure 220, the elastic drive member 122 is stretched or compressed accordingly. To improve the operational stability of the limiting post 121, in another embodiment of this application, such as... Figure 3 As shown, the first limiting structure 120 may further include a guide block 124, which is sleeved on the guide post 123. In this case, the limiting post 121 is fixedly connected to the guide block 124. Furthermore, the guide block 124 can provide guidance and limiting for the guide post 123, thereby improving the operational stability of the guide post 123 and further enhancing the stability of the elastic drive member 122. Correspondingly, in this case, during the connection of the guide post 123 and the elastic drive member 122, one end of the elastic drive member 122 can be fixedly connected to the surface of the guide post 123, thereby indirectly forming an assembly relationship between the elastic drive member 122 and the guide post 123.

[0082] Therefore, in this embodiment of the application, the first limiting structure further includes a guide post 123 and a guide block 124. The guide post 123 is fixed to the support body 110 and extends along the second direction. The guide block 124 and the elastic drive member 122 are movably sleeved on the guide post 123, and the limiting post 121 is fixedly connected to the guide block 124.

[0083] Furthermore, the guide post 123 can be located entirely outside the tray body 110, and in the second direction, by providing end caps or similar means at opposite ends of the guide post 123, separation of the elastic drive member 122 and the like from the guide post 123 can be prevented. To further reduce the dimensions of the card tray 100 and the entire card holder in the direction perpendicular to the third direction, in one specific embodiment of this application, such as... Figure 3 As shown, the tray body 110 can be provided with a mounting groove 112. In the third direction, the mounting groove 112 can be recessed relative to the surface of the tray body 110. By accommodating the guide post 123 in the mounting groove 112, the size of the card tray 100 and the entire card holder can be further reduced in the third direction.

[0084] Of course, in the above embodiments, to ensure proper engagement between the limiting post 121 of the first limiting structure 120 and the second limiting structure 220, at least a portion of each of the guide section 221 and the blocking section 222 of the second limiting structure 220 can extend into the mounting groove 112. In another embodiment of this application, at least a portion of the limiting post 121 can extend out of the receiving groove in a third direction to the outside of the support body 110, so that the limiting post 121 can properly engage with the second limiting structure 220.

[0085] The guide post 123 can be fixedly connected to the tray body 110 by means of adhesive bonding or other methods. In other embodiments of this application, screws or other fasteners can also be used to fix the guide post 123 to the tray body 110. In order to reduce costs, in one specific embodiment of this application, the tray 100 can be formed of materials such as plastic. In this case, it may have an adverse effect on the assembly stability between the guide post 123 and the tray body 110.

[0086] Based on this, in one specific embodiment of this application, the card holder 100 may further include a fixing piece 125, and the fixing piece 125 is a metal structural component. Meanwhile, as... Figure 3 As shown, fixing plates 125 can be fixed to both ends of the guide post 123, and each fixing plate 125 is embedded within the holder body 110. In this case, since the guide post 123 is mounted on the metal fixing plate 125, and the fixing plate 125 has a relatively larger contact area with the holder body 110, a relatively reliable connection can be established between the guide post 123 and the fixing plate 125, as well as between the fixing plate 125 and the holder body 110, thereby improving the installation stability of the guide post 123. Accordingly, in this case, the holder body 110 can be made of plastic material, which can significantly reduce the weight and cost of the card holder 100.

[0087] As described above, the card holder 100 can be installed in the receiving cavity of the base 200 along the first direction, and correspondingly, the card holder 100 can be removed from the receiving cavity along the first direction. Based on this, in order to improve the reliability and stability of the fit between the card holder 100 and the base 200 in the first direction, such as... Figure 4 As shown, the base 200 may also include a guide rail 240, so as to provide guidance for the movement of the card holder 100 and the base 200 in the first direction, thereby further improving the assembly and disassembly efficiency of the card holder 100 and reducing the assembly and disassembly difficulty of the card holder 100.

[0088] In detail, such as Figure 4 As shown, and in combination Figure 1In this embodiment, in the third direction, guide rails 240 are provided on both opposite sides of the base body 210, and the support body 110 is limited between the guide rails 240. Specifically, the guide rail 240 can be a long groove-shaped structure, and the guide rail 240 extends along the first direction as a whole. Alternatively, multiple hollow holes can be opened on the aforementioned long groove-shaped guide rail 240 to significantly reduce the weight of the guide rail 240, thereby reducing the weight of the entire card holder, which facilitates the development of electronic devices towards thinner and lighter designs.

[0089] Based on the card holder disclosed in any of the above embodiments, this application also discloses an electronic device, which includes a device body and any of the above card holders, wherein the card holder is mounted on the device body. More specifically, the device body has a groove structure for accommodating the card holder, and the seat 200 in the card holder is mounted in the aforementioned groove structure of the device body, and the seat 200 can be fixedly connected to the device body by welding or screws or other connecting parts. Of course, electronic devices may also typically include other components such as batteries and displays, which will not be listed here.
