Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to a card tray assembly and an electronic device. Background Art

[0002] Currently, most electronic devices have communication capabilities, primarily achieved by reading a carrier's SIM card. Mobile phones, in particular, typically have a card slot and tray, allowing for the sending and receiving of text messages and the making and receiving of calls by inserting and removing the card. In existing technology, because the card tray is built into the phone, its size inevitably negatively impacts the limited internal space. Summary of the Invention

[0003] The present application aims to provide a card tray assembly and an electronic device, by setting a mounting groove on the base body at a position relative to the step groove of the card tray structure, and setting part of the top rod in the mounting groove. The space in the mounting groove can be used to shorten the width of the entire card tray assembly, thereby facilitating the arrangement of other structures in a limited space.

[0004] In order to achieve the above-mentioned purpose, an embodiment of the first aspect of the present application provides a card holder assembly, including: a card holder structure, which is provided with a step groove extending along the insertion direction; a base structure, which is detachably connected to the card holder structure, and the base structure includes a base body, and a built-in mounting groove is provided at a position corresponding to the step groove on the base body; a push rod, a part of the push rod is provided in the mounting groove, and the other part of the push rod extends out of the base body; wherein, the push rod can move along the extension direction of the mounting groove.

[0005] According to the embodiment of the card tray assembly provided by the present application, it mainly includes a detachably connected card tray structure and a card seat structure, wherein the card tray structure is provided with a step groove, and the card seat structure includes two structures, a base body and a push rod, wherein an inwardly extending mounting groove is provided on the base body corresponding to the step groove. By arranging part of the push rod in the mounting groove, the dead space of the base body can be utilized to place the traditional external push rod in the mounting groove corresponding to the step groove, thereby reducing the size perpendicular to the extension direction of the mounting groove, that is, reducing the size of the entire card tray assembly in the width direction. Specifically, the mounting groove is embedded, and its position corresponds to the step groove on the card tray structure, and does not occupy additional space. The push rod is mainly used to push out the card tray structure. When the part of the push rod extending out of the base body is subjected to external force, generally an external force in the length direction, the force will be transmitted to the inside under the action of its own structure, thereby pushing the card tray structure outward, so as to facilitate the disassembly and assembly of the card tray structure.

[0006] The card tray structure is used to carry card-like structures such as SIM cards and memory cards. When the card tray structure is inserted into the card holder structure, the card tray assembly will identify and read the specific card-like structure, thereby realizing the corresponding storage and communication functions.

[0007] It can be understood that the overall volume of the card tray assembly will also decrease due to the reduction in the volume of the card seat structure.

[0008] The moving direction of the push rod is along the extending direction of the mounting groove. It can be understood that the extending direction of the mounting groove is the same as the extending direction of the edge of the seat body, so the push rod also moves along the direction of the edge.

[0009] It should be emphasized that the present application utilizes the idle corner space in the traditional structure of the base body and sets the external ejector rod in the idle space, which can greatly reduce the overall width of the card tray assembly.

[0010] The electronic device provided in the embodiment of the second aspect of the present application includes: a mainboard; and the card tray assembly as in the embodiment of the first aspect described above, which is arranged on the mainboard.

[0011] According to an embodiment of the electronic device provided in the present application, it mainly includes a main board and a card tray assembly. By setting the card tray assembly on the main board, after the card tray structure is inserted into the card tray assembly, the main board can be used to read specific information, thereby realizing the corresponding function.

[0012] The mainboard can be arranged inside the electronic device or as an external structure of the electronic device.

[0013] In addition, since the electronic device includes the card tray assembly of the above embodiment, it has the beneficial effects of the embodiment of the above card tray assembly.

[0014] Among them, electronic devices include mobile phones, tablets, cameras, camcorders, notebooks and other devices that require communication cards or storage cards.

[0015] Additional aspects and advantages of the present application will become apparent in the following description or may be learned through practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

Furthermore, "and / or" in the specification and claims refers to at least one of the connected entities, and the character " / " generally indicates an "or" relationship between the connected entities.

[0034] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0035] The electronic device provided in the embodiments of the present application may be a mobile phone, tablet, camera, camcorder, notebook, or other device that requires a communication card or a storage card.

[0036] Refer to the following Figures 1 to 14 Describe the card tray assembly and electronic device provided according to the embodiments of the present application.

[0037] like Figure 1 、 Figure 2 and Figure 10 As shown, one embodiment of the present application proposes a card holder assembly 200, including: a card holder structure 202, the card holder structure 202 is provided with a step groove 204 extending along the insertion direction; a base structure 100, which is detachably connected to the card holder structure 202, and the base structure 100 includes a base body 102, and a built-in mounting groove 1022 is provided at a position corresponding to the step groove 204 on the base body 102; a push rod 104, a part of the push rod 104 is provided in the mounting groove 1022, and the other part of the push rod 104 extends out of the base body 102; wherein, the push rod 104 can move along the extension direction of the mounting groove 1022.

[0038] According to the embodiment of the card tray assembly 200 provided in this application, it mainly includes a detachably connected card tray structure 202 and a card seat structure 100, wherein, as Figure 11 and Figure 12 As shown, a step groove 204 is provided on the card holder structure 202, and the card seat structure includes two structures: a base body 102 and a push rod 104, wherein an inwardly extending mounting groove 1022 is provided on the base body 102 corresponding to the step groove. By arranging part of the push rod 104 in the mounting groove 1022, the dead corner space of the base body 102 can be utilized to place the traditional external push rod in the mounting groove corresponding to the step groove, thereby reducing the size perpendicular to the extension direction of the mounting groove 1022, that is, reducing the size of the entire card holder assembly 200 in the width direction. Specifically, the mounting groove 1022 is embedded, and its position corresponds to the step groove 204 on the card holder structure, and does not occupy any additional space. The push rod 104 is mainly used to push out the card holder structure 202. When the part of the push rod 104 extending out of the base body 102 is subjected to external force, generally the external force in the length direction, the force will be transferred to the inside under the action of its own structure, thereby pushing the card holder structure 202 outward to facilitate the disassembly and assembly of the card holder structure 202.

[0039] It should be emphasized that the card tray structure 202 is used to carry card-like structures such as SIM cards and memory cards. The card tray assembly 200 will identify and read the specific card-like structure when the card tray structure 202 is inserted, thereby realizing corresponding storage and communication functions.

[0040] It can be understood that the overall volume of the card tray assembly 200 will also decrease due to the reduction in the volume of the card base structure 100.

[0041] The moving direction of the push rod 104 is along the extending direction of the mounting groove 1022 . It can be understood that the extending direction of the mounting groove 1022 is the same as the extending direction of the edge of the base 102 , so the push rod 104 also moves along the direction of the edge.

[0042] The specific shape of the top rod 104 is as follows: Figure 13 As shown, the thickness of the rod body is greatly reduced, which is conducive to reducing the left and right width dimensions.

[0043] It should be emphasized that the present application utilizes the idle corner space in the traditional structure of the base 102 and sets the external push rod 104 in the idle space, which can greatly reduce the overall width of the card tray assembly 200.

[0044] In a specific embodiment, the cross section of the mounting groove 1022 is in a right-angle shape, with two adjacent sides exposed to the outside.

[0045] In another specific embodiment, the cross section of the mounting groove 1022 is U-shaped.

[0046] Furthermore, the push rod 104 specifically includes: a rod body 1042 disposed in the installation groove 1022; a joint 1044 connected to the rod body 1042, and on the cross section of the base body 102, the projection of the joint 1044 does not overlap with the projection of the base body 102.

[0047] The top rod 104 mainly includes two parts: a rod body 1042 and a joint 1044. The two parts are connected to each other. The joint 1044 is outside the mounting groove 1022, and the rod body 1042 is inside the mounting groove 1022. When the joint 1044 on the outside is subjected to external force, the force will be transferred to the rod body 1042, so that the joint 1044 and the rod body 1042 slide inward along the mounting groove 1022 together, thereby realizing the ejection of the card support structure 202.

[0048] Among them, the position of the joint 1044 does not coincide with the projection of the base body 102 on the cross section, that is, in the height and width direction of the base body 102, the joint 1044 and the base body 102 are staggered, so that when the rod body 1042 is set in the installation groove 1022, part of the space adjacent to the installation groove 1022 can be saved to facilitate the arrangement of other structures.

[0049] Furthermore, if Figure 9 As shown, a solder foot 1062 is provided on the rear side of the base 102, and the card tray assembly 200 also includes: a plurality of terminals 1064, which are provided on the base 102, and one end of the terminal 1064 extends from the rear side of the base 102; an insulating member 1066, which is provided on the same side of the base 102 as the solder foot 1062, and the insulating member 1066 protrudes from the base 102; wherein, the distance between the end of the insulating member 1066 extending from the base 102 and the base 102 is less than the distance between the solder foot 1062 and the base 102.

[0050] Solder pins 1062 are provided on the rear side of the base 102 to facilitate soldering the base 102 to a fixed position within the electronic device 300. Typically, the card holder of a mobile phone is located at the bottom and can be soldered to a small plate located at the bottom. To ensure that the card tray assembly 200 recognizes the card tray structure 202, the card tray assembly 200 is also provided with multiple terminals 1064 for transmitting information. These terminals are located on the rear side of the base 102 and can connect to the connection contacts on the small plate, thereby facilitating the transmission of information to the small plate, thereby facilitating the reading of information from the memory card or SIM card in the card tray assembly 200.

[0051] The base 102 is also provided with an insulating member 1066 that wraps around the terminals 1064, thereby reducing the possibility of accidental contact or short circuits caused by the connection of two adjacent terminals 1064. Specifically, in this application, the insulating member 1066 is not simply flush with the edge of the base 102, but is required to protrude from the base 102. When protruding outward, the protruding end must be lower than the position of the solder pins 1062 to avoid blocking the solder pins 1062 and ensure a proper connection.

[0052] It should be noted that in the present application, by setting the insulating part 1066 on the rear side of the seat body 102 and extending a part toward the rear side, that is, a protruding part is blocked on the terminal 1064, the protection capability of the terminal 1064 can be improved, and at the same time, the overall length of the card seat can be reduced to a certain extent after stretching the insulating part 1066.

[0053] Furthermore, the insulating member 1066 can be made of plastic, and its ductility can be utilized to move it back toward the upper portion of the rear row of solder pins 1062, fully utilizing the unused space there and making stacking more compact. Furthermore, by moving the plastic back while maintaining the same length (extending beyond the edge of the housing but not beyond the location of solder pins 1062), the other end of the plastic can be shortened accordingly, reducing the overall length of the card tray assembly 200.

[0054] Furthermore, if Figure 4 and Figure 5 As shown, an arc-shaped cavity 1024 is provided on the rear side of the base body 102, and the card tray assembly 200 also includes: a rotating rod 1046, which is provided at one end of the rod body 1042 away from the joint 1044, and a rotating part adapted to the shape of the arc-shaped cavity 1024 is provided on the rotating rod 1046. The rotating part is located in the arc-shaped cavity 1024, and the rotating rod 1046 can rotate relative to the base body 102 through the rotating part.

[0055] An arc-shaped cavity 1024 is formed on the rear side of the base 102 by machining, so that the card holder structure 202 can be pushed out by the rotation of the rotating rod 1046. Specifically, a rotating rod 1046 is provided at the end of the rod 1042 away from the joint 1044. The rotating rod 1046 is disposed inside the housing and has a rotating portion that can be placed in the arc-shaped cavity 1024. When the top rod 104 is forced to extend inward, the rotating rod 1046 is pushed to move under the action of the arc-shaped cavity 1024. At this time, the other end of the rotating rod 1046 can generate a certain thrust on the card holder structure 202, thereby pushing the card holder structure 202 out.

[0056] In this embodiment, by utilizing the unused space on the rear side of base 102 to house rotating rod 1046, the length of the entire card tray assembly 200, namely, the dimension along the extension of mounting slot 1022, can be reduced. Furthermore, the rotational force fulcrum of rotating rod 1046 is the inner wall of arc-shaped cavity 1024, which reduces the number of rivets 1050. Furthermore, rotating rod 1046 itself does not require a hole, thus reducing its volume and facilitating a compact design.

[0057] Furthermore, if Figure 2 、 Figure 3 and Figure 4 As shown, it also includes: a limit buckle 1026, which is provided on the base 102, and the limit buckle 1026 is used to limit the position of the rotating rod 1046 together with the arc cavity 1024; wherein, the end of the limit buckle 1026 away from the base 102 can be bent.

[0058] By setting a limit buckle 1026 on the base body 102, the moving position of the rotating rod 1046 can be limited together with the arc cavity 1024. The arc cavity 1024 plays a guiding role. After the top rod 104 receives external force, the force is transferred to the rotating rod 1046, and the position of the rotating rod 1046 is continuously adjusted to finally realize the ejection of the card support structure 202.

[0059] It should be noted that the limiting buckle 1026 is located on the base 102 and can be set in the arc-shaped cavity 1024 for the convenience of limiting.

[0060] Among them, when installing the rotating rod 1046, it is mainly realized by using the bendable end of the limit buckle 1026. Specifically, the rotating rod 1046 is first installed obliquely into the arc cavity 1024, and then Figure 4 As shown, the bent portion of the limit buckle 1026 is bent to limit the rotation rod 1046.

[0061] Furthermore, if Figure 6 and Figure 7 As shown, a rotating hole 1048 is provided on the rotating rod 1046, and a rivet 1050 is provided in the rotating hole 1048. The relative rotation of the rotating rod 1046 and the base body 102 is achieved through the rivet 1050; wherein the shape of the arc cavity 1024 is adapted to the shape of the rivet 1050.

[0062] In another structural solution, rivets 1050 are also used to rotationally fix the rotating rod 1046. Specifically, a rotation hole 1048 is provided on the rotating rod 1046. By driving the rivet 1050 into the rotation hole 1048, the rotating rod 1046 can be rotated relative to the base 102. At this time, when the rotating rod 1046 is received by the ejector pin 104, the card tray structure 202 in the card tray assembly 200 can be pushed out.

[0063] It should be emphasized that in order to save unnecessary external space, the shape of the arc cavity 1024 in this solution is adapted to the shape of the rivet 1050, which can also reduce additional external space to a certain extent.

[0064] Furthermore, if Figure 7 and Figure 8 As shown, it also includes: a switch spring 108, which is arranged in the base body 102, and the two ends of the switch spring 108 are respectively a fixed end 1082 and a detection end 1084, and the fixed end 1082 is welded to the side of the base body 102 in the width direction.

[0065] By setting the switch spring 108 in the base 102 and welding the fixed end 1082 of the switch spring 108 to a side wall in the width direction, compared with welding to the rear end position, the overall length direction dimension of the structure of this solution is smaller, and the length can be shortened.

[0066] When the switch spring 108 is welded to the side, it can be connected to the welding foot 1062 of the base body 102, thereby achieving normal circuit function, that is, judging whether the card holder structure 202 is inserted in place.

[0067] Furthermore, it also includes: a detection seat 110, which is arranged in the seat body 102, and the detection seat 110 is used to cooperate with the detection end 1084 to determine whether the card holder structure 202 is inserted into place.

[0068] By setting a detection seat 110 in the seat body 102, after the card holder structure 202 is inserted into place, the detection end 1084 will be popped open, thereby separating the detection end 1084 from the detection seat 110. At this time, the detection seat 110 can send corresponding instructions to the controller, thereby realizing the judgment of whether the card holder structure 202 is inserted into place.

[0069] like Figure 14 As shown, the electronic device 300 provided in the embodiment of the second aspect of the present application includes: a mainboard 302; as in the above-mentioned first aspect embodiment, the card tray assembly 200 is arranged on the mainboard 302.

[0070] According to an embodiment of the electronic device 300 provided in the present application, it mainly includes a main board 302 and a card tray assembly 200. By setting the card tray assembly 200 on the main board 302, after the card tray structure 202 is inserted into the card tray assembly 200, the main board 302 can be used to read specific information, thereby realizing the corresponding function.

[0071] The mainboard 302 may be disposed inside the electronic device 300 , or may serve as an external structure of the electronic device 300 .

[0072] In addition, since the electronic device 300 includes the card slot component 200 of the above embodiment, it has the beneficial effects of the embodiment of the above card slot component 200.

[0073] Among them, the electronic device 300 includes devices such as mobile phones, tablets, cameras, video cameras, notebooks, etc. that have a need for communication cards or storage cards.

[0074] This application also proposes a card slot component 200 of a specific embodiment, which re-adjusts the internal layout of the card slot component 200, makes full use of the idle space to reduce the overall size of the card slot component 200. Specifically: the use of the new ejector rod 104 and the rotating rod 1046 not only reduces the occupied space but also reduces the number of parts. In addition, by adopting a new detection switch (i.e., the switch spring piece 108), which is adjusted from a "C" - shaped main body to a "one" - shaped main body, the space occupied by the card slot length is reduced. Through the above design, the length of the new stacked card slot is greatly reduced, realizing the miniaturization of the device, thus leaving more space for the battery compartment, ultimately improving the battery life of the terminal product and achieving thinness and lightness, and enhancing the user experience.

[0075] First, the plastic (i.e., the insulating part 1066) that wraps the terminal 1064 of the upper card slot (i.e., the card slot component 200) is moved backward to the upper part beside the rear - row iron shell welding foot 1062, making full use of the idle space here. The plastic moves backward while the length of the plastic body remains unchanged (not exceeding the iron shell welding foot 1062), so the other end of the plastic is correspondingly shortened, and the overall length of the card slot is reduced. Secondly, a convex arc - shaped cavity 1024 body (i.e., the arc - shaped cavity 1024) is stamped from the rear - end iron shell wall towards the iron shell welding foot 1062 direction. This arc - shaped cavity 1024 body is used to accommodate the rotating rod 1046 of the ejecting mechanism, also making use of the idle space in the upper part beside the iron shell welding foot 1062. Moreover, the fixing method of the new rotating rod 1046 reduces the rivet 1050 parts and occupies less space, and the length of the card slot is reduced again. Finally, for the "C" - shaped detection switch of the stacked card slot, its fixing part is adjusted from the rear end to the side and is fixed to the iron shell by laser spot welding instead of the existing SMT welding method. The main body becomes a "one" - shaped, realizing the reduction of the card slot length. In addition, by using the idle space (i.e., the installation slot 1022) in the upper left of the "convex" - shaped cavity of the card slot, the ejector rod 104 is arranged at this position, reducing the width of the stacked card slot. Ultimately, the miniaturization of the device can be further improved.

[0076] Specifically, the plastic that wraps the terminal 1064 at the tail of the existing stacked card slot is generally flush with the iron shell wall at the tail. In this application, first, the plastic that wraps the terminal 1064 of the upper card slot is moved backward to the upper part beside the rear - row iron shell welding foot 1062, making full use of the idle space here and stacking more compactly; the plastic moves backward while the length of the plastic body remains unchanged (the plastic exceeds the iron shell wall but does not exceed the iron shell welding foot 1062), so the other end of the plastic can be correspondingly shortened, and the overall length of the card slot is reduced.

[0077] For the existing ejection mechanism of the stacked card holder, due to the limitation of the rear iron shell wall, the rivet 1050 and the rotating rod 1046 occupy a relatively large space inside.

[0078] Meanwhile, this new design can eliminate the rivet 1050 part that fixes the rotating rod 1046 in the existing ejection mechanism of the stacked card holder. The fixing method of the rotating rod 1046 in the new solution is as follows: First, a vertical bar extends from the iron shell at the position where the rotating rod 1046 is placed. One side in the middle of the rotating rod 1046 of the new structure protrudes in an arc shape, and there is an arc-shaped notch on the other side; after the rotating rod 1046 is obliquely inserted into the arc-shaped cavity 1024 of the iron shell wall, the vertical bar in the arc-shaped notch of the rotating rod 1046 is bent, so that together with the arc-shaped cavity 1024 of the iron shell, the up-and-down direction of the rotating rod 1046 is limited; by using the arc-shaped protrusion and notch shape of the rotating rod 1046 and designing reasonable dimensions, the left-and-right direction of the rotating rod 1046 is also limited and it will not fall off during the movement.

[0079] The working principle of the new ejection mechanism of the stacked card holder is the same as that of the existing ejection mechanism of the stacked card holder. Both use a ejector pin to push the ejector rod 104, and the ejector rod 104 pushes the rotating rod 1046 to rotate, and the rotating rod 1046 ejects the card tray; however, it is different from the specific ejection mechanism of the existing stacked card holder. The rotation force fulcrum of the rotating rod 1046 in this solution is not the rivet 1050, but the arc-shaped iron shell wall, which serves as the lever force fulcrum. By using this method, first, the rivet 1050 part can be eliminated, and second, the rotating rod 1046 itself does not need to be drilled, and its volume can be reduced.

[0080] In another compromise solution, the rivet 1050 is not eliminated, but the rear iron shell wall is stamped out an arc shape (without cavity) towards the iron shell welding leg 1062 direction. This arc is used to accommodate the rotating rod 1046 and also avoid the rivet 1050, and the length of the card holder is also shortened to a certain extent.

[0081] The detection switch of the existing stacked card holder is generally roughly in a "匚" shape. The side with the SMT welding leg 1062 is the fixed part, and the other side is the elastic contact part. For the detection switch of this solution, its fixed part is adjusted to the side, and the fixing method is changed to laser spot welding to the iron shell and connected to the PCB through the iron shell welding leg 1062 for conduction. This solution only includes the elastic contact part in the length direction, occupying less space of the card holder, thus realizing the reduction of the card holder length.

[0082] To solve this problem, the new stacked card holder punches out an arc-shaped cavity 1024 from the rear iron shell wall towards the iron shell welding leg 1062 direction. This arc-shaped cavity 1024 is used to accommodate the rotating rod 1046 of the ejection mechanism, and also makes use of the idle space above the iron shell welding leg 1062. The entire ejection mechanism moves forward, and the length of the card holder is shortened.

[0083] Most importantly, to prevent users from mistakenly inserting the card tray backward, the card tray is typically designed (in cross-section) with a convex shape, and the card holder has a corresponding convex cavity. The ejector pin 104 of existing laminated card holders is typically located to the side of the convex opening of the card holder, occupying a large amount of width. The new laminated card holder of the present invention utilizes the unused space to the upper left of the convex cavity, positioning the ejector pin 104 there. This reduces the width of the laminated card holder.

[0084] According to the embodiments of the card tray assembly, card tray assembly and electronic device of the present application, by setting a mounting groove at the edge of the base body, part of the top rod is set in the mounting groove, and the space of the mounting groove can be used to shorten the width of the entire card tray assembly, which is convenient for the arrangement of other structures in a limited space.
