Description

Technical Field

[0001] This application belongs to the technical field of electronic devices, and particularly relates to a card tray and card seat assembly and an electronic device. Background Art

[0002] The SIM card, as a core part of electronic devices such as mobile phones, is used to implement important functions such as telephone and text message communication. In related technologies, the card tray and card seat system for carrying the SIM card in an electronic device is as Figure 1 shown, and includes a card seat 101, a card tray 102, a thumbtack 103, and a push rod 104. A swing rod 1011 and a push rod 1012 are installed on the card seat 101. The swing rod 1011 can swing around a fixed axis, and the push rod 1012 can move back and forth. A thumbtack hole 1021 is formed in the card tray 102 for the thumbtack 103 to insert. A silicone ring is sleeved on the push rod 104 to prevent water from entering through the thumbtack hole 1021.

[0003] The usage process of the card tray and card seat system in related technologies includes:

[0004] When inserting the card tray 102, install the SIM card on the card tray 102 and then directly insert it into the card seat 101;

[0005] When removing the card tray 102, insert the thumbtack 103. The thumbtack 103 passes through the thumbtack hole 1021 on the card tray 102 and acts on the push rod 104. The push rod 104 acts on the push rod 1012, and the push rod 1012 moves backward, driving the swing rod 1011 to swing around the axis. Finally, the swing rod 1011 ejects the card tray 102.

[0006] It can be seen that for the card tray and card seat system in related technologies, when removing the card tray 102, it is necessary to use the thumbtack 103. The thumbtack 103 itself is small in size, extremely easy to lose, and not convenient to carry, resulting in the card tray 102 being inconvenient to remove from the card seat. Summary of the Invention

[0007] The purpose of the embodiments of this application is to provide a card tray and card seat assembly and an electronic device, which can solve the problem that the card tray is inconvenient to remove from the card seat.

[0008] In a first aspect, the embodiments of this application provide a card tray and card seat assembly, which includes: a card tray and a card seat;

[0009] The card seat includes a first body part, a first elastic member, and a clamping structure. An opening groove is provided on the first body part. The card tray is inserted into or detached from the card seat through the opening groove; the first elastic member is located at the bottom of the opening groove, and the clamping structure is located on the first side wall of the opening groove. The clamping structure has an adjustable clamping groove;

[0010] The card slot includes a second body portion and an elastic arm. The elastic arm is located on a first side of the second body portion. The first sidewall corresponds to the first side. The elastic arm includes a protruding portion.

[0011] Wherein, the assembled state between the card slot and the card holder includes a first assembled state and a second assembled state.

[0012] In the first assembled state, the protruding portion extends into the adjustable card slot. A sidewall of the adjustable card slot away from the slot bottom abuts against an end face of the protruding portion facing away from the slot bottom, blocking the protruding portion from moving in the opening direction of the opening slot. The first direction is the depth direction of the opening slot.

[0013] In the second assembled state, the protruding portion disengages from the adjustable card slot and is located on a side of the adjustable card slot away from the slot bottom.

[0014] In a second aspect, an embodiment of the present application provides an electronic device, which includes the card slot and the card holder assembly as described in the first aspect.

[0015] In the embodiment of the present application, by adjusting the presence or absence of a gap between the adjustable card slots, the assembled state between the card slot and the card holder can be changed. Among them, when there is a gap between the opposite sidewalls of the adjustable card slot, after inserting the card slot into the opening slot of the card holder, since the protruding portion on the card slot extends into the adjustable card slot, a sidewall of the adjustable card slot away from the slot bottom abuts against an end face of the protruding portion facing away from the slot bottom, blocking the protruding portion from moving in the opening direction of the opening slot. At this time, the card slot can be assembled in the card holder and the card slot can be prevented from detaching from the card holder; when the gap between the opposite sidewalls of the adjustable card slot is closed, the protruding portion on the card slot cannot limit the relative movement between the card slot and the card holder through the adjustable card slot, so that the card slot can move in the opening direction of the opening slot under the elastic force of the first elastic member, that is, the first elastic member can eject the card slot from the card holder, facilitating the removal of the card slot from the card holder.

[0027] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, rather than all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application belong to the scope of protection of the present application.

[0028] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order different from those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0029] To facilitate the understanding of the card tray and card holder assembly and the electronic device provided in the embodiments of the present application, the related technologies, nouns, and terms in the present application will be explained first.

[0030] Such as Figure 1As shown, the card holder system in the related art includes a card holder 101, a card tray 102, a thimble 103, and a ejector rod 104. When removing the card tray 102, it is necessary to insert the thimble 103 so that the thimble 103 passes through the thimble hole 1021 on the card tray 102 and acts on the ejector rod 104. The ejector rod 104 acts on the push rod 1012, and the push rod 1012 moves backward, driving the swing rod 1011 to swing around the axis. Finally, the swing rod 1011 ejects the card tray 102. This card holder system has at least the following defects:

[0031] 1) To remove the card tray 102 from the card holder system, it is necessary to use the thimble 103. However, the thimble 103 itself is small in size and is extremely easy to lose and not convenient to carry. Many times when the user wants to change the card but there is no thimble 103 available, other things will be used to replace the thimble 103. At this time, due to the mismatch between the size of the substitute and the thimble hole 1021, the substitute being too sharp or the substitute not being firm enough, etc., it is very likely to cause problems such as cracking of the thimble hole 1021, blockage of the thimble hole 1021, or damage to the ejector rod 104, resulting in insufficient convenience for the user to change the card.

[0032] 2) There may be other holes in the area of the electronic device near the card holder system. As Figure 2 shown, there is a microphone (Microphone, Mic) sound hole 105 near the card holder system of the smart phone. The size of the Mic sound hole 105 is similar to that of the thimble hole 1021. When the user changes the card, it is easy to mistake the Mic sound hole 105 for the thimble hole 1021. Inserting the thimble 103 into the Mic sound hole 105 may damage the Mic and cause the microphone function to fail.

[0033] 3) It is necessary to open a thimble hole 1021 on the card tray 102. During the user's use process, the thimble hole 1021 is prone to dust accumulation, affecting the appearance of the product. At the same time, the existence of the thimble hole 1021 increases the risk of water ingress into the electronic device and raises the waterproof cost.

[0034] In the card tray and card holder assembly provided by the embodiment of the present application, by adjusting the presence or absence of the gap between the adjustable card slots, the assembly state between the card tray and the card holder can be changed, realizing inserting the card tray into the card holder or removing the card tray from the card holder, and the process of removing the card tray from the card holder can be simplified. In addition, in the embodiment of the present application, there is no need to open a thimble hole on the card tray, which can improve the appearance integrity of the electronic device with this card tray and card holder assembly, reduce the risk of water ingress into the electronic device and the waterproof cost. In addition, it can also reduce the risk of damage to the components in other holes near the card tray and card holder assembly on the electronic device.

[0035] Next, with reference to the accompanying drawings, through specific embodiments and their application scenarios, the card tray and card holder assembly and the electronic device provided by the embodiments of the present application will be described in detail.

[0036] Referring to Figure 3 , the cato and card seat assembly provided by the embodiment of the present application includes: a cato 1 and a card seat 2;

[0037] The card seat 2 includes a first body portion 21, a first elastic member 22 and a clamping structure 23. An opening groove 211 is provided on the first body portion 21. The cato 1 is inserted into or detached from the card seat 2 through the opening groove 211; The first elastic member 22 is located at the bottom 2111 of the opening groove 211, and the clamping structure 23 is located on the first side wall 2112 of the opening groove 211. The clamping structure 23 has an adjustable clamping groove 231;

[0038] The cato 1 includes a second body portion 11 and an elastic arm 12. The elastic arm 12 is located on the first side 111 of the second body portion 11. The first side wall 2112 corresponds to the first side 111. The elastic arm 12 includes a protrusion 121;

[0039] Wherein, the assembled state between the cato 1 and the card seat 2 includes a first assembled state and a second assembled state;

[0040] In the first assembled state, the protrusion 121 extends into the adjustable clamping groove 231. The side wall of the adjustable clamping groove 131 away from the bottom 2111 abuts against the end face of the protrusion 121 facing away from the bottom 2111, blocking the protrusion 121 from moving towards the opening direction of the opening groove 211;

[0041] In the second assembled state, the protrusion 121 disengages from the adjustable clamping groove 231 and is located on the side of the adjustable clamping groove 231 facing away from the bottom 2111.

[0042] Wherein, during the process of switching from the first assembled state to the second assembled state, the first elastic member 22 is in a compressed state, the adjustable clamping groove 231 is closed, the protrusion 121 disengages from the adjustable clamping groove 231, and the cato 1 moves towards the opening direction of the opening groove 211 under the elastic force of the first elastic member 22.

[0043] Wherein, the first assembled state can represent the state of installing the cato 1 into the card seat 2. In this state, the protrusion 121 extending into the adjustable clamping groove 231 is limited by the side wall of the adjustable clamping groove 231 to restrict the cato 1 from moving towards the opening direction of the opening groove 211, thereby fixing the cato 1 in the card seat 2.

[0044] In some embodiments, in the first assembled state, the first elastic member 22 may also be in a compressed state. At this time, the movement of the cartridge 1 in the opening direction of the opening slot 211 is restricted by the side wall of the adjustable slot 231 on the side away from the slot bottom 2111, and a thrust force in the opening direction of the opening slot 211 is provided to the cartridge 1 by the first elastic member 22, so that the end face of the protrusion 121 facing away from the slot bottom 2111 remains in contact with the side wall of the adjustable slot 231 on the side away from the slot bottom 2111, thereby restricting the movement of the cartridge 1 in the opening direction of the opening slot 211 and restricting the movement of the cartridge 1 in the direction of the slot bottom 2111 of the opening slot 211.

[0045] In other embodiments, in the first assembled state, the protrusion 121 may be clamped between the opposite side walls of the adjustable slot 231 along the first direction X, and the first direction X is the depth direction of the opening slot 211. In this way, the movement of the cartridge 1 in the opening direction of the opening slot 211 and the movement of the cartridge 1 in the direction of the slot bottom 2111 of the opening slot 211 can be restricted.

[0046] In addition, the second assembled state may represent a state in which the cartridge 1 can be removed from the card seat 2. In this state, the protrusion 121 is disengaged from the adjustable slot 231 and is located on the side of the adjustable slot 231 facing away from the slot bottom 2111, so that the protrusion 121 cannot be limited by the adjustable slot 231.

[0047] To achieve the transition from the first assembled state to the second assembled state, the gap on the adjustable slot 231 can be closed, and the first elastic member 22 provides an elastic force in the opening direction of the opening slot 211 to the cartridge 1, pushing the cartridge 1 to slide in the opening direction of the opening slot 211 until the protrusion 121 crosses the position of the adjustable slot 231 and moves to the side of the adjustable slot 231 facing away from the slot bottom 2111, thereby realizing ejecting the cartridge 1 from the opening slot 211 and enabling the cartridge 1 to be removed from the card seat 2.

[0048] In some embodiments, the first elastic member 22 may be an elastic structure such as a spring or a spring piece, and no specific limitation is made here. For example: as Figure 4 shown, the first elastic member 22 includes two spring pieces, and the two spring pieces are arranged at intervals on the slot bottom 2111 of the opening slot 211. In this way, the elastic force of the first elastic member 22 can be increased by using the two spaced spring pieces, and the elastic force provided by the first elastic member 22 to the cartridge 1 is more balanced in the second direction Y, where the second direction Y is perpendicular to the first direction X and parallel to the plane where the cartridge 1 is located.

[0049] It should be noted that, in addition to the first assembly state and the second assembly state, the assembly state between the card tray 1 and the card holder 2 may also include other assembly states, for example: during the insertion of the card tray 1 from the open end of the opening slot 211 into the card holder 2, there is a gap between the two opposite side walls of the adjustable card slot 231, and the protrusion 121 has not yet slid to the position of the gap along the first direction X. In order to facilitate the description of the embodiments of the present application, the first assembly state, the second assembly state, and the switching process between the first assembly state and the second assembly state are usually used as examples for illustration, which does not constitute a specific limitation here.

[0050] In some embodiments, the snap-fit structure 23 can form an adjustable slot 231, that is, the width of the gap between the opposite side walls of the adjustable slot 231 is adjustable. In this way, when a gap is formed between the opposite side walls of the adjustable slot 231, the protrusion 121 on the card tray 1 will extend into the adjustable slot 231 under the elastic force of the elastic arm 12; in the process of gradually reducing the gap between the opposite side walls of the adjustable slot 231, the protrusion 121 on the card tray 1 will slide outward from the adjustable slot 231 until the gap between the opposite side walls of the adjustable slot 231 is completely closed, and the protrusion 121 is completely disengaged from the adjustable slot 231 and is not affected by the limiting effect of the adjustable slot 231.

[0051] In some embodiments, the gap width between the two opposite side walls of the adjustable slot 231 on the snap-fit structure 23 can be changed by an external force acting on the card tray 1 .

[0052] For example, when the card tray 1 is inserted into the opening slot 211 and the user presses the card tray 1, there is a gap between the two opposite side walls of the adjustable card slot 231. When the protrusion 121 is pressed by the user and moves along the first direction X to the position of the adjustable card slot 231, the elastic force of the elastic arm 12 in the depth direction of the adjustable card slot 231 causes the protrusion 121 to enter the adjustable card slot 231, so that the card tray 1 and the card holder 2 are in the first assembly state. When the card tray 1 and the card holder 2 are in the first assembly state, In this case, if the user continues to press the card tray 1, the adjustable card slot 231 may be closed under the action of the user's pressing force. When the user releases the hand pressing the card tray 1, the protrusion 121 passes over the closed adjustable card slot 231 under the action of the first elastic member 22 and moves to the side of the adjustable card slot 231 facing away from the bottom 2111 of the slot, so that the card tray 1 and the card holder 2 are in the second assembly state. At this time, the protrusion 121 is not limited by the adjustable card slot 231, and the card tray 1 can be easily removed from the card holder 2.

[0053] Of course, in some other embodiments, the snap - fit structure 23 may include a driving member. In this case, under the driving action of the driving member, the gap width between the opposite side walls of the adjustable slot 231 is adjusted. For example, in the first assembled state, the driving member controls the opening of the adjustable slot 231; during the process of switching from the first assembled state to the second assembled state, the driving member controls the closing of the adjustable slot 231. Optionally, the driving member may adopt an electric driving structure or an electromagnetic driving structure, which is not specifically limited herein.

[0054] In the embodiments of the present application, by adjusting the presence or absence of the gap between the adjustable slots, the assembled state between the card tray and the card seat can be changed. Among them, when there is a gap between the opposite side walls of the adjustable slot, after the card tray is inserted into the opening slot of the card seat, since the protruding portion on the card tray extends into the adjustable slot, the side wall of the adjustable slot away from the slot bottom abuts against the end surface of the protruding portion facing away from the slot bottom, blocking the movement of the protruding portion in the opening direction of the opening slot. At this time, the card tray can be assembled in the card seat and the card tray can be prevented from detaching from the card seat; when the gap between the opposite side walls of the adjustable slot is closed, the protruding portion on the card tray cannot limit the relative movement between the card tray and the card seat through the adjustable slot, so that the card tray can move in the opening direction of the opening slot under the elastic force of the first elastic member, that is, the first elastic member can eject the card tray from the card seat, facilitating the removal of the card tray from the card seat.

[0055] As an alternative embodiment, the snap - fit structure 23 includes: a fixed block 232, a second elastic member 233, a sliding rod 234, a slider 235, and a baffle 236;

[0056] The sliding rod 234 is fixedly connected to the first body portion 21, the fixed block 232 is fixedly connected to the sliding rod 234, and the slider 235 is elastically connected to the fixed block 232 through the second elastic member 233;

[0057] The fixed block 232 is located on the side of the slider 235 facing away from the slot bottom 2111, the baffle 236 is located on the side of the slider 235 facing the slot bottom 2111, and the slider 235 can move along the sliding rod 234 between the fixed block 232 and the baffle 236; the gap between the slider 235 and the fixed block 232 forms the adjustable slot 231;

[0058] In the first assembled state, the slider 235 and the fixed block 232 are spaced apart, that is, there is a gap between the opposite side walls of the adjustable slot 231, and the end surface of the protruding portion 121 facing away from the slot bottom 2111 abuts against the end surface of the fixed block 232 facing the slot bottom 2111 to block the movement of the protruding portion 121 in the opening direction of the opening slot 211;

[0059] During the process of switching from the first assembled state to the second assembled state, the slider 235 abuts against the fixed block 232 until the raised portion 121 slides along the outer surface of the slider 235 and abuts against the outer surface of the fixed block 232, and then the slider 235 and the fixed block 232 are spaced apart.

[0060] Among them, the slider 235 can move between the fixed block 232 and the baffle 236 along the slide bar 234. The slide bar 234 can extend radially in the first direction X. A through hole 2354 is formed in the slider 235, and the slide bar 234 passes through the through hole 2354 in the slider 235. The fixed block 232 and the baffle 236 are respectively fixed relative to the first body portion 21 and are located on opposite sides of the slider 235 along the first direction X. In this way, the slider 235 can slide along the slide bar 234 until it abuts against the fixed block 232 or the baffle 236.

[0061] In some embodiments, such as Figure 4 or Figure 5 as shown, the opposite ends of the slide bar 234 can be fixedly connected to the first body portion 21. For example, the opposite ends of the slide bar 234 are riveted and fixed on the first body portion 21, and the fixed block 232 is fixed on the slide bar 234.

[0062] In some embodiments, such as Figure 5 as shown, the baffle 236 can be fixed on the first body portion 21. For example, it bends and extends from the portion of the first body portion 21 below the slide bar 234 towards the direction close to the slide bar 234 to limit the sliding range of the slider 235 along the slide bar 234.

[0063] In some embodiments, the second elastic member 233 can be a spring. A receiving groove 2353 can be provided on the slider 235. One end of the second elastic member 233 facing the slider 235 abuts against the bottom of the receiving groove 2353. In this way, when the second elastic member 233 is compressed, the second elastic member 233 can be received in the receiving groove 2353 so that the end faces of the fixed block 232 and the slider 235 can abut against each other to realize the closing of the adjustable card slot 231.

[0064] During operation, the slide bar 234 provides a guiding function for the slider 235, so that the slider 235 reciprocates along the first direction X, and the gap width of the adjustable card slot 231 is adjustable. The second elastic member 233 is used to provide an elastic force to the slider 235 so that when the card holder 1 is not subject to an external force, a certain distance is maintained between the slider 235 and the fixed block 232. When the user pushes the card holder 1, under the action of this thrust and the limiting effect of the baffle 236 on the slider 235, the second elastic member 233 is compressed and deformed, and the distance between the slider 235 and the fixed block 232 is reduced until the adjustable card slot 231 is closed, so that the gap width of the adjustable card slot 231 located between the slider 235 and the fixed block 232 is adjustable.

[0065] It should be noted that in the first assembled state, the adjustable slot 231 is open, and the protruding portion 121 extends into the adjustable slot 231 between the slider 235 and the fixed block 232, so that the end face of the fixed block 232 facing the bottom of the slot 2111 abuts against the end face of the protruding portion 121 facing away from the bottom of the slot 2111, thereby restricting the movement of the protruding portion 121 in the opening direction of the opening slot 211, that is, restricting the detachment of the card tray 1 from the card seat 2.

[0066] During the process of switching from the first assembled state to the second assembled state, the adjustable slot 231 closes, and the protruding portion 121 can abut against the outer surface of the slider 235. Thus, under the action of the elastic force provided by the first elastic member 22 in the opening direction of the opening slot 211, when the card tray 1 is pushed to move in the opening direction of the opening slot 211, the protruding portion 121 can cross the position of the adjustable slot 231 and abut against the outer surface of the fixed block 232.

[0067] In some embodiments, the outer surface of at least one of the slider 235 and the fixed block 232 can be a cylindrical surface, such as a cylindrical surface or a prismatic surface. In this way, when the protruding portion 121 abuts against the outer surface of the slider 235 or the fixed block 232, it can move smoothly along the first direction X, and the first direction X is the depth direction of the opening slot 211.

[0068] In some embodiments, the card tray 1 can be inserted into the opening slot 211, and a first pressing force is applied to the bottom 2111 of the opening slot 211, so that the card tray 1 and the card seat 2 are in the first assembled state. Among them, under the action of the first pressing force, the protruding portion 121 moves along the first direction X towards the bottom 2111 of the opening slot 211, and the adjustable slot 231 opens. In this way, when the protruding portion 121 moves to the position of the adjustable slot 231, under the action of the elastic force of the elastic arm 12 towards the depth direction of the adjustable slot 231, the protruding portion 121 enters the adjustable slot 231.

[0069] In some embodiments, in the above first assembled state, when a second pressing force is continuously applied to the card tray 1 towards the bottom 2111 of the opening slot 211, the card tray 1 and the card seat 2 can be driven to switch from the first assembled state to the second assembled state, and the second pressing force can be greater than the first pressing force.

[0070] In some embodiments, the end face of the fixed block 232 facing the slider 235 can have the same size as the end face of the slider 235 facing the fixed block 232. In this way, during the process of switching from the first assembled state to the second assembled state, when the fixed block 232 and the slider 235 come into contact with each other to close the adjustable slot 231, the tip of the protruding portion 121 can slide smoothly from the surface of the slider 235 to the surface of the fixed block 232.

[0071] Of course, the distance between the fixed block 232 and the first side 111 can be less than or equal to the distance between the slider 235 and the first side 111. In this way, when the fixed block 232 and the slider 235 are in contact with each other to close the adjustable slot 231, the tip of the protrusion 121 can also smoothly slide from the surface of the slider 235 to the surface of the fixed block 232.

[0072] In some embodiments, under the action of the second pressing force, the protrusion 121 continues to move along the first direction X towards the bottom 2111 of the opening slot 211, so that the protrusion 121 overcomes the elastic force of the elastic arm 12 and disengages from the adjustable slot 231 and moves to be connected to the side wall of the slider 235, and the opposite side walls of the adjustable slot 231 are closed. In this way, when the user stops the pressing operation, under the action of the first elastic member 22, the entire card tray 1 moves towards the open end of the opening slot 211. When the protrusion 121 passes over the adjustable slot 231, since the adjustable slot 231 is closed, the protrusion 121 will not enter the adjustable slot 231. Therefore, the adjustable slot 231 does not limit the movement of the card tray 1 towards the open end of the opening slot 211, thus realizing the switching from the first assembled state to the second assembled state.

[0073] In other embodiments, under the action of the second pressing force, the adjustable slot 231 closes, squeezing the protrusion 121 out of the adjustable slot 231. In this way, when the user stops the pressing operation, under the action of the first elastic member 22, the entire card tray 1 moves towards the open end of the opening slot 211, and the distance that the first elastic member 22 pushes the card tray 1 towards the open end of the opening slot 211 is greater than the distance that the protrusion 121 slides along the first direction X on the outer surface of the slider 235 when the adjustable slot 231 is closed. In this way, when the user releases the hand pressing the card tray 1, the first elastic member 22 first pushes the protrusion 121 to move to the side of the adjustable slot 231 opposite to the bottom 2111 of the slot. In this way, when the adjustable slot 231 opens, the protrusion 121 has already moved to the side of the adjustable slot 231 opposite to the bottom 2111 of the slot, and the user can easily take out the card tray 1, realizing the switching from the first assembled state to the second assembled state.

[0074] Wherein, after the user releases the hand pressing the card tray 1, the speed at which the first elastic member 22 pushes out the card tray 1 is greater than the speed at which the adjustable slot 231 is reset, that is, before the first elastic member 22 pushes out the card tray 1 so that the protrusion 121 is on the side of the adjustable slot 231 opposite to the bottom 2111 of the slot, the adjustable slot 231 is in a closed state. This process can be achieved by designing the elastic force, elastic structure type, elastic force propagation path, etc. of the first elastic member 22 and the second elastic member 233. For example: the first elastic member 22 is a shrapnel with a larger elastic force and a faster ejection speed, and the second elastic member 233 is a spring with a smaller elastic force and a slower ejection speed.

[0075] In some other embodiments, under the action of the second pressing force, the adjustable slot 231 is closed, and the protrusion 121 moves to the side of the adjustable slot 231 facing the slot bottom 2111. At this time, the protrusion 121 abuts against the outer surface of the slider 235. After the user releases the hand pressing the card tray 1, the card tray 1 moves toward the open end of the open slot 211 under the elastic force of the first elastic member 22. At this time, the structure of the slider 235 can be designed so that the slider 235 follows the protrusion 121 and moves toward the open end of the open slot 211 until the slider 235 abuts against the fixed block 232. The adjustable slot 231 is then closed, so that the protrusion 121 can continue to pass over the closed adjustable slot 231 under the elastic force of the first elastic member 22, and after the protrusion 121 passes over the closed adjustable slot 231, the force between the protrusion 121 and the slider 235 disappears, and the slider 235 moves relative to the fixed block 232 toward the side of the slot bottom 2111 under the action of the second elastic member 233, so that the gap width of the adjustable slot 231 is increased, so that when the user subsequently inserts the card tray 1 into the card holder 2, the card tray 1 and the card holder 2 are in the first assembly state.

[0076] For example: Figure 4 , Figure 5 and Figure 6 As shown, the slider 235 includes a second rod body 2351 and a second tapered structure 2352;

[0077] The second rod 2351 is fixedly connected to the first end of the second conical structure 2352; the first end of the second conical structure 2352 faces away from the bottom 2311 of the groove, and the second end of the second conical structure 2352 faces toward the bottom 2311 of the groove; for example: Figure 6 As shown, the first end of the second tapered structure 2352 is the left end surface, and the second end of the second tapered structure 2352 is the top end of the right tapered surface;

[0078] The second end of the first tapered structure 2322 is disposed opposite to the first end of the second tapered structure 2352 , and the second end of the second elastic member 233 is connected to the first end of the second tapered structure 2352 .

[0079] Wherein, the diameter of the second rod body 2351 is smaller than the diameter of the conical surface at the end of the second conical structure 2352 facing the fixed block 232. In this way, a conical surface inclined towards the bottom 2311 of the groove can be formed by the second conical structure 2352, and during the sliding process of the protruding portion 121 relative to the second conical structure 2352 towards the opening direction of the opening groove 211, the acting force between the protruding portion 121 and the conical surface of the second conical structure 2352 can be increased, causing the second conical structure 2352 to move towards the opening direction of the opening groove 211 following the protruding portion 121 until the end surface of the second conical structure 2352 abuts against the fixed block 232, so that the adjustable card slot 231 is closed.

[0080] In some embodiments, during the process of the card holder and card seat assembly switching from the first assembled state to the second assembled state, when the protruding portion 121 disengages from the adjustable card slot 231, the second elastic member 233 is in a compressed state. Under the elastic force of the second elastic member 233, the protruding portion 121 slides along the conical surface of the second conical structure 2352 in a direction away from the bottom 2311 of the groove, and the slider 235 slides towards the direction close to the fixed block 232 under the acting force between the slider 235 and the protruding portion 121, driving the second elastic member 233 to deform until the end surface of the first conical structure 2322 fits against the end surface of the second conical structure 2352. When the protruding portion 121 slides to abut against the conical surface of the first conical structure 2322, the second conical structure 2352 slides towards the side away from the first conical structure 2322.

[0081] In this embodiment, by providing a conical surface structure at the end of the slider 235 close to the fixed block 232, when the protruding portion 121 abuts against the outer surface of the slider 235, and after the user releases the hand pressing the card holder 1, during the process of the card holder 1 moving towards the opening end of the opening groove 211 under the elastic force of the first elastic member 22, the mutual acting force between the protruding portion 121 and the conical surface of the second conical structure 2352 can be increased. As a result, under this acting force, the slider 235 moves towards the direction close to the fixed block 232 following the protruding portion 121 until it abuts against the fixed block 232, so that the adjustable card slot 231 is closed. And due to the limiting effect of the fixed block 232 on the slider 235, the slider 235 no longer continues to move towards the opening end of the opening groove 211. The elastic force of the first elastic member 22 can overcome the mutual acting force between the protruding portion 121 and the conical surface of the second conical structure 2352 and the elastic force of the second elastic member 233, enabling the protruding portion 121 to move beyond the adjustable card slot 231 and continue to move towards the opening end of the opening groove 211. In this way, the smoothness and reliability of the switching between the first assembled state and the second assembled state of the card holder 1 and the card seat 2 can be improved.

[0082] As an alternative embodiment, the first body portion 21 further includes a guiding groove 212 located on the second sidewall 2113 of the opening groove 211. The second sidewall 2113 and the first sidewall 2112 are opposite sidewalls of the opening groove 211. When the card holder 1 is inserted into the opening groove 211, the second side 112 of the second body portion 11 is located within the guiding groove 212, and the card holder 1 moves along the extending direction of the guiding groove 212, so that the card holder and the card socket assembly can be switched between the first assembled state and the second assembled state.

[0083] Wherein, the second side 112 is the side of the second body portion 11 corresponding to the second sidewall 2113, that is, the second side 112 and the first side 111 are opposite sides of the second body portion 11 along the first direction X.

[0084] In this embodiment, among the opposite sidewalls of the card socket 2 along the first direction X, the first sidewall is used to deploy the clamping structure 23, and the second sidewall is used to deploy the guiding groove 212. In this way, the card holder 1 can be clamped between the guiding groove 212 and the clamping structure 23. On the one hand, under the limiting and guiding action of the guiding groove 212, the card holder 1 can only reciprocate relative to the card socket 2 along the first direction X. On the other hand, the protruding portion 121 on the card holder 1 can be pressed against the outer surface of the clamping structure 23 or into the adjustable card slot 231 on the clamping structure 23 through the guiding groove 212, which can limit the moving space of the card holder 1 relative to the card socket 2 and improve the smoothness and reliability of the switching between the first assembled state and the second assembled state of the card socket 2 and the card holder 1.

[0085] As an alternative embodiment, two bumps 1111 are provided on the first side 111 at intervals along the first direction X. The elastic arm 12 is mounted between the two bumps 1111, and there is a second gap 113 between the elastic arm 12 and the first side 111.

[0086] The middle region of the elastic arm 12 is bent towards the direction away from the first side 111 to form a protruding portion 121.

[0087] In the second assembled state, the protruding portion 121 abuts against the outer surface of the fixed block 232, and the elastic arm 12 deforms towards the direction close to the first side 111.

[0088] In some embodiments, during the process of the assembly state between the card tray 1 and the card seat 2 switching from the first assembly state to the second assembly state, the user first further presses the card tray 1 to disengage the protrusion 121 from the adjustable card slot 231. Thereafter, under the action of the pressing force of the user, the tip of the protrusion 121 slides along the surface of the slider 235, and the card tray 1 further approaches the bottom 2111 of the opening slot 211, causing the first elastic member 22 to be in a compressed state; when the pressing force of the user disappears, the first elastic member 22 provides an elastic force to the card tray 1 in the opening direction of the opening slot 211 and pushes the protrusion 121 to slide along the surface of the slider 235 in the opening direction of the opening slot 211. During this process, due to the second tapered structure 2352 of the slider 235, the distance between the protrusion 121 and the first side 111 gradually shortens, the elastic arm 12 deforms in the direction approaching the first side 111, presses the tip of the protrusion 121 against the surface of the slider 235, and pushes the slider 235 to move in the direction approaching the fixed block 232 until the end face of the slider 235 contacts the end face of the fixed block 232, causing the adjustable card slot 231 to close. At this time, the slider 235 stops moving in the opening direction of the opening slot 211, while the tip of the protrusion 121 can continue to slide along the surface of the slider 235 in the opening direction of the opening slot 211 until the tip of the protrusion 121 crosses the end face of the slider 235 and the fixed block 232, then the card tray 1 and the slider 235 are no longer in contact, and the slider 235 moves towards the bottom 2111 of the opening slot 211 under the elastic force of the second elastic member 233, so that the slider 235 and the fixed block 232 are spaced apart.

[0089] In this embodiment, through two bumps 1111 spaced apart on the first side 111, both ends of the elastic arm 12 are fixedly connected to the second body portion 11, and the middle of the elastic arm 12 is suspended between the two bumps 1111. In this way, the gap between the elastic arm 12 and the first side 111 can be used as the movement space of the elastic arm 12. When the protrusion 121 abuts against the outer surface of the slider 235 or the fixed block 232 along the first direction X, the elastic arm 12 moves in the direction approaching the first side 111 and provides an elastic force to the protrusion 121 in the direction away from the first side 111.

[0090] As an alternative embodiment, the fixed block 232 includes a first rod body 2321 and a first tapered structure 2322;

[0091] The first rod body 2321 is fixedly connected to the first end of the first tapered structure 2322; the first end of the first tapered structure 2322 faces away from the slider 235, and the second end of the first tapered structure 2322 faces the slider 235; as Figure 6 shown, the first end of the first tapered structure 2322 is the top of the left tapered surface, and the second end of the first tapered structure 2322 is the right end face.

[0092] The second end of the first conical structure 2322 is opposite to the first end of the slider 235, and the first end of the second elastic member 233 is connected to the second end of the first conical structure 2322, the second end of the second elastic member 233 is connected to the first end of the slider 235, the first end of the slider 235 is facing away from the bottom of the groove 2311, and the second end of the slider 235 is facing the bottom of the groove 2311.

[0093] In some embodiments, when the card tray 1 is inserted into the card holder 2 so that the card tray 1 and the card holder 2 are in a first assembly state, the top end of the protrusion 121 slides along the surface of the fixed block 232 until the protrusion 121 enters the adjustable slot 231. During this process, since the fixed block 232 includes a first conical structure 2322, when the top end of the protrusion 121 slides along the surface of the fixed block 232, the distance between the protrusion 121 and the first side 111 gradually decreases, and the elastic arm 12 deforms toward the first side 111 and presses the top end of the protrusion 121 onto the surface of the fixed block 232. When the top end of the protrusion 121 slides to the position of the adjustable slot 231, the elastic force provided by the elastic arm 12 to the protrusion 121 can push the protrusion 121 into the adjustable slot 231.

[0094] In the present embodiment, by providing a first conical structure 2322 at one end of the fixed block 232 facing the slider 235, during the process of inserting the card holder 1 into the open slot 211, the first conical structure 2322 can be used to push the protrusion 121 in advance toward the direction close to the first side edge 111 to cause the elastic arm 12 to deform. In this way, when the protrusion 121 moves to the position of the adjustable card slot 231, the protrusion 121 can be pushed into the adjustable card slot 231 based on the elastic force of the elastic arm 12.

[0095] Of course, in other embodiments, the surface of the fixing block 232 may be a cylindrical surface or an inclined surface, and it is sufficient that the elastic arm 12 is deformed toward the first side edge 111 before the protrusion 121 moves from the open end of the opening slot 211 to the position of the adjustable slot 231. For example, the surface of the fixing block 232 is a cylindrical surface, and when the card holder 1 is inserted into the opening slot 211, the distance between the fixing block 232 and the first side edge 111 is smaller than the distance between the elastic arm 12 and the first side edge 111 when the card holder 1 is not under stress.

[0096] In some embodiments, in order to improve the reliability of the limiting effect of the adjustable slot 231 on the fixed block 232 when the fixed block 232 enters the adjustable slot 231, and to enable the fixed block 232 to be smoothly disengaged from the adjustable slot 231 during the process of switching the card tray 1 and the card holder 2 from the first assembly state to the second assembly state, the elastic arm 12 can be improved accordingly.

[0097] As an alternative implementation, as Figure 7 and Figure 8 shown, the elastic arm 12 includes a first segment 122, a second segment 123, a third segment 124, and a fourth segment 125 that are sequentially connected along the first direction X, and the first segment 122 is located on the side of the second segment 123 facing away from the bottom 2111 of the groove;

[0098] The included angle between the first segment 122 and the second segment 123 is less than or equal to 90°;

[0099] The included angle between the third segment 124 and the fourth segment 125 is greater than 90°;

[0100] In the state where the elastic arm 12 is not deformed, the first segment 122 and the fourth segment 125 extend along the first direction X.

[0101] It should be noted that the convex portion 121 is composed of the first segment 122 and the second segment 123.

[0102] In some embodiments, as Figure 9 shown, when the tray 1 and the card seat 2 are in the first assembled state, the first segment 122, the second segment 123, the third segment 124, and the fourth segment 125 are sequentially distributed from the open end of the open groove 211 to the bottom 2111 of the open groove 211. In this way, the side wall on the side of the adjustable card slot 231 away from the bottom 2111 (i.e., the end face of the fixed block 232 facing the slider 235) overlaps with the second segment 123 to limit the movement of the tray 1 towards the open end of the open groove 211. At this time, since the included angle between the first segment 122 and the second segment 123 is less than or equal to 90°, and the second elastic member 233 generates an elastic force towards the bottom of the adjustable card slot 231, in this way, it is difficult for the second segment 123 to move relative to the fixed block 232 towards the open direction of the open groove 211, and the tray 1 can be firmly restricted within the open groove 211 of the card seat 2.

[0103] In other embodiments, as Figure 10 shown, during the process of the tray 1 and the card seat 2 switching from the first assembled state to the second assembled state, the convex portion 121 disengages from the adjustable card slot 231 and slides to abut against the outer surface of the slider 235. During this process, the top of the side wall on the side of the adjustable card slot 231 close to the bottom 2311 will slide from the fourth segment 125 to the third segment 124. Since the included angle between the third segment 124 and the fourth segment 125 is greater than 90°, the smoothness of the sliding of the elastic arm 12 relative to the side wall of the adjustable card slot 231 can be improved.

[0104] Therefore, the embodiment of the present application can improve the limiting firmness of the card holder 2 to the card tray 1 in the first assembled state, and improve the smoothness of the card tray 1 moving relative to the card holder 2 during the process of switching from the first assembled state to the second assembled state, and can improve the smoothness of the user's pressing operation on the card tray 1.

[0105] In some embodiments, the second tapered structure 2352 may be provided only on the slider 235, and the first tapered structure 2322 may not be provided on the fixed block 232.

[0106] In some embodiments, the first tapered structure 2322 may be provided only on the fixed block 232, and the second tapered structure 2352 may not be provided on the slider 235.

[0107] In some embodiments, the first tapered structure 2322 may be provided on the fixed block 232, and the second tapered structure 2352 may be provided on the slider 235.

[0108] For the convenience of description, in the embodiment of the present application, it is usually exemplified by the case where the first tapered structure 2322 is provided on the fixed block 232 and the second tapered structure 2352 is provided on the slider 235.

[0109] For the convenience of understanding the card tray and card holder assembly provided by the embodiment of the present application, taking the relative position relationship between the card tray 1 and the card holder 2 as shown in Figures 9 to 11 The card tray and card holder assembly will be explained in the first assembled state, the second assembled state, and the switching process between the first assembled state and the second assembled state.

[0110] As shown in Figure 9 Insert the card tray 1 into the card holder 2 from the opening groove 211, and press the card tray 1 so that the card tray 1 and the card holder 2 are in the first assembled state. At this time, there is a gap between the end face of the first tapered structure 2322 and the end face of the second tapered structure 2352, and the protrusion 121 enters this gap, and the second segment 123 is in contact with the end face of the first tapered structure 2322, thereby restricting the card tray 1 from detaching from the opening groove 211.

[0111] As shown in Figure 10 After the card tray 1 and the card holder 2 are in the first assembled state, the user continues to press the card tray 1 into the opening groove 211 so that the card tray 1 and the card holder 2 are switched to the second assembled state. During the process of switching from the first assembled state to the second assembled state, the protrusion 121 first slides relative to the slider 235 towards the bottom of the groove 2111 under the action of the user's pressing force, so that the tip of the protrusion 121 moves to abut against the outer surface of the slider 235. During this process, the first elastic member 22 and the second elastic member 233 are compressed. Thereafter, as shown in Figure 11As shown, when the user stops pressing the cartridge 1, under the elastic force of the first elastic member 22 and the second elastic member 233, the convex portion 121 slides in the opening direction of the opening groove 211, and pushes the slider 235 towards the fixed block 232, so that the end face of the first conical structure 2322 fits with the end face of the second conical structure 2352 until the tip of the convex portion 121 crosses the end faces of the first conical structure 2322 and the second conical structure 2352. After that, the tip of the convex portion 121 abuts against the conical surface of the first conical structure 2322, and the end of the first conical structure 2322 away from the slider 235 is inclined away from the first side 111 relative to the end of the first conical structure 2322 close to the slider 235. In this way, under the elastic force of the second elastic member 233, the tip of the convex portion 121 slides along the end of the first conical structure 2322 close to the slider 235 towards the end of the first conical structure 2322 away from the slider 235, so as to eject the cartridge 1 from the card seat 2.

[0112] It is worth noting that for the cartridge and card seat assembly provided in this application, the ejector pin, ejector pin hole, ejector rod, push rod and swing rod are removed. There is no need to use an ejector pin to take out the cartridge. Instead, a pressing and ejecting structure is designed to press and eject the cartridge. In this way, when the user changes the card, they only need to press the cartridge inward, and the cartridge will pop out after letting go, greatly improving the convenience of user use. In addition, since the ejector pin hole is cancelled, there is no longer the problem of dust accumulation in the ejector pin hole and the problem of water ingress from the ejector pin hole, improving the appearance integrity of the electronic device with this cartridge and card seat assembly; at the same time, with the pressing and ejecting design, there is no longer the problem of other functions being damaged due to user's misoperation, improving the reliability of the electronic device. Moreover, by cancelling the ejector pin, ejector pin hole, ejector rod, push rod and swing rod, there is no longer a need for waterproofing of the ejector pin hole, reducing the cost of the electronic device with this cartridge and card seat assembly.

[0113] The embodiment of the present application also provides an electronic device, which includes the cartridge and card seat assembly provided in any one of the embodiments of the present application as Figures 3 to 11 described above.
