Description

Technical Field

[0001] This application relates to the field of electronic device technology, and more particularly to a card tray and electronic device. Background Technology

[0002] In electronic devices, a notch is usually provided on the frame, and an electronic card (such as a memory card or SIM card) is inserted into the notch using a card tray. This allows the electronic card in the card tray to connect with the corresponding connector, thereby enabling the electronic card to be electrically connected to the electronic device.

[0003] In related technologies, a card tray has a door that seals the notch and a tray for loading electronic cards, with the door and tray fixedly connected by screws. However, this connection method has obvious defects. Due to slight differences in the size and specifications of connectors produced by different manufacturers, or the influence of manufacturing tolerances such as production errors, the position of the assembled connector relative to the notch set on the frame will deviate. After the tray loaded with electronic cards is accurately inserted into the connector of the electronic device, the door cannot adapt to different manufacturing tolerances, resulting in uneven gaps between the door and the inner wall of the notch when the door is embedded in the notch, affecting the appearance. In some cases, when the deviation is large, the door of the card tray may not even be embedded in the notch.

[0004] To address the aforementioned issues, the relevant technologies urgently need improvement. Utility Model Content

[0005] This application provides a card tray and electronic device to at least solve the aforementioned problems in the related art.

[0006] To achieve the above objectives, this application provides the following technical solution: a card tray, which includes a tray and a door;

[0007] The door is located at one end of the tray along its length, and the door is buoyantly connected to the tray to adjust its position relative to the tray. The card tray carries the electronic cards via the tray.

[0008] One end of the tray along its length is the end point where the electronic device is inserted.

[0009] In some embodiments, the pallet has a groove at one end along its length, the groove being:

[0010] Extending along the length of the tray, the door is slidably connected to a track via a slider, allowing it to float along the length of the tray; or,

[0011] Extending along the thickness direction of the pallet, the door is slidably connected to a track via a slider, allowing it to float along the thickness direction of the pallet; or,

[0012] Extending along the width of the pallet, the door is slidably connected to the slide rail via a slider, allowing it to float in the width direction of the pallet.

[0013] In some embodiments, the card holder also includes a connecting block located between the door and the slider, with the door connected to the slider via the connecting block.

[0014] In some embodiments, the chute includes a first chute and a second chute, the second chute being formed on the chute wall of the first chute and communicating with the inside and outside of the first chute;

[0015] The slider is slidably connected to the first groove, and the connecting block passes through the second groove and is slidably connected to the second groove.

[0016] In some embodiments, the cross-sectional shape of the slider is the same as that of the first groove, and the cross-sectional shape of the connecting block is the same as that of the second groove;

[0017] The cross-sectional dimensions of the slider are smaller than those of the first groove, and the cross-sectional dimensions of the connecting block are smaller than those of the second groove, so that the door floats in a direction perpendicular to the extension of the groove.

[0018] In some embodiments, the chute extends in the width direction of the tray, a limiting hole is formed in the wall of the chute, and the door also includes a limiting block that can be movably inserted into the limiting hole and connected to the slider. The limiting block is used to limit the floating distance of the door in the width direction of the tray.

[0019] In some embodiments, the chute extends in the width direction of the tray, and the slider has a first protrusion in the length direction of the tray, the first protrusion being used to define the floating distance of the door in the length direction of the tray.

[0020] In some embodiments, the chute extends in the width direction of the tray, and the connecting block has a second protrusion in the thickness direction of the tray, the second protrusion being used to limit the floating distance of the door in the thickness direction of the tray.

[0021] In some implementations, the limiting block is made of an elastic material;

[0022] During assembly, the limiting block abuts against the groove wall and undergoes elastic compression deformation.

[0023] When the cassette is assembled, the limiting block extends into the limiting hole and returns to its original state.

[0024] In some embodiments, this application also provides an electronic device, which includes the aforementioned card tray.

[0025] In the aforementioned card tray, when the card tray is inserted into an electronic device, the tray containing the electronic card engages with the connector inside the electronic device. The connector within the electronic device forms a positioning reference for the tray, ensuring its engagement accuracy. Simultaneously, the door, through a floating connection structure, makes minor adjustments relative to the tray to automatically compensate for assembly errors and automatically correct positional deviations at the notch in the electronic device. Thus, during assembly, the tray containing the electronic card achieves precise engagement with the electronic device, and the door, through its floating connection structure, achieves high-precision fitting with the notch in the electronic device, thereby enhancing adaptability to manufacturing tolerances while ensuring insertion accuracy.

[0032] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

For example, the steps described in this application can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this application can be achieved, and this is not limited herein.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] In related technologies, there is a positioning deviation problem when the notch on the frame of electronic devices mates with the door of the card tray. Traditional screw fixing methods result in an unadjustable door position. When connector assembly errors accumulate, the gap between the door and the notch becomes uneven or even impossible to insert. Fixed connection structures are not only inefficient in assembly, but also lack the ability to compensate for component deformation or dimensional fluctuations, affecting the product's appearance quality and reliability.

[0036] To address these issues, researchers observed that the assembly error of the card tray mainly stemmed from the misalignment of the connector installation position. By analyzing the connection method between the door and the tray, they discovered that combining end positioning with floating adjustment could achieve position compensation while ensuring the accuracy of the insertion direction. Further research revealed that setting a floating door at the end of the tray could maintain the overall structural rigidity of the card tray while also providing the door with self-adjusting capabilities.

[0037] Therefore, please combine Figure 1 In some embodiments, this application proposes a card tray including a tray 11 and a door 12; the door 12 is located at one end of the tray 11 in the longitudinal direction, and the door 12 is buoyantly connected to the tray 11 to adjust the position of the door 12 relative to the tray 11, and the card tray carries an electronic card through the tray 11; one end of the tray 11 in the longitudinal direction is the end point when the tray 11 is inserted into an electronic device. Exemplarily, the card tray can be a SIM card tray. Figure 1 This is a schematic diagram of the cassette structure.

[0038] In the aforementioned card tray, when the card tray is inserted into an electronic device, the tray 11 containing the electronic card engages with the connector inside the electronic device. The connector within the electronic device forms a positioning reference for the tray 11, ensuring the engagement accuracy of the tray 11. Simultaneously, the door portion 12, through a floating connection structure, makes minor adjustments relative to the tray 11 to automatically compensate for assembly errors and automatically correct positional deviations at the notch in the electronic device. Thus, during assembly, the tray 11 containing the electronic card achieves precise engagement with the electronic device, and the door portion 12, through its floating connection structure, achieves high-precision fitting with the notch in the electronic device, thereby enhancing adaptability to manufacturing tolerances while ensuring insertion accuracy.

[0039] It is understood that tray 11 refers to a rigid support structure for loading electronic cards. The structure of tray 11 for loading electronic cards adopts an existing design and will not be described in detail here. Tray 11 has a length direction, a width direction, and a thickness direction, and its length direction is consistent with the movement trajectory of the inserted electronic device. Door 12 refers to a cover structure that closes the notch of the device to prevent external dust from entering the electronic device through the notch, while also making the electronic device look simple and aesthetically pleasing. Floating connection refers to a mechanical connection method that allows limited displacement in three-dimensional space, so that door 12 can be adjusted in three-dimensional directions.

[0040] Please combine Figure 2 In some embodiments, the tray 11 has a groove 111 at one end in the length direction, the groove 111 extending along the length direction of the tray 11, and the door 12 is slidably connected to the groove 111 via a slider 13 to float in the length direction of the tray 11. Alternatively, the groove 111 extends along the thickness direction of the tray 11, and the door 12 is slidably connected to the groove 111 via a slider 13 to float in the thickness direction of the tray 11. Alternatively, the groove 111 extends along the width direction of the tray 11, and the door 12 is slidably connected to the groove 111 via a slider 13 to float in the width direction of the tray 11. Figure 2 This is a schematic diagram of the exploded structure of Cato.

[0041] Thus, when the slide 111 is set along the length direction, the door 12 can move back and forth during insertion and removal via the slider 13 to compensate for the positional deviation of the electronic device frame notch and the connector in the length direction of the tray 11; when the slide 111 is set along the thickness direction, the door 12 can float up and down to adjust its height position to compensate for the positional deviation of the electronic device frame notch and the connector in the thickness direction of the tray 11; when the slide 111 is set along the width direction, the door 12 can move left and right to correct the horizontal misalignment to compensate for the positional deviation of the electronic device frame notch and the connector in the width direction of the tray 11. The three slide 111 orientations replace the traditional screw connection with a mechanical guide structure, allowing the door 12 to form an adjustable degree of freedom in a single direction while retaining the positioning constraints in other directions.

[0042] Please combine Figure 2 In some embodiments, the card holder further includes a connecting block 14, which is located between the door portion 12 and the slider 13, and the door portion 12 is connected to the slider 13 through the connecting block 14. The slide groove 111 includes a first groove and a second groove, the second groove being formed on the groove wall of the first groove and communicating with the inside and outside of the first groove; the slider 13 is slidably connected to the first groove, and the connecting block 14 passes through the second groove and is slidably connected to the second groove.

[0043] Thus, the first groove provides the main sliding track for the slider 13, and the second groove provides the auxiliary sliding track for the connecting block 14. The two work together to form a double-track sliding structure, which can limit the movement in the direction perpendicular to the slide groove 111, thereby preventing the door 12 from falling off. At the same time, by opening the second groove on the groove wall of the first groove, the overall structure of the slide groove 111 is simple, occupies less space, and is easier to process.

[0044] In some embodiments, the cross-sectional shape of the slider 13 is the same as that of the first groove, and the cross-sectional shape of the connecting block 14 is the same as that of the second groove; the cross-sectional dimension of the slider 13 is smaller than that of the first groove, and the cross-sectional dimension of the connecting block 14 is smaller than that of the second groove, so that the door portion 12 floats in a direction perpendicular to the extension of the slide groove 111.

[0045] Thus, when the slider 13 slides within the first groove, the identical cross-sectional shape ensures alignment in the sliding direction, while the gap created by dimensional differences allows the slider 13 to have displacement space in the direction perpendicular to the extension of the groove 111. Simultaneously, when the connecting block 14 slides within the second groove, the identical shape maintains guiding accuracy, and the gap created by dimensional differences allows the connecting block 14 to displace in the direction perpendicular to the extension of the groove 111. The door portion 12 can automatically adjust its posture according to the position of the external notch, eliminating assembly interference problems caused by production errors or connector dimensional deviations.

[0046] In some optional embodiments, the cross-sectional shape of the slider 13 and the first groove can be rectangular, circular, triangular, sector-shaped, or trapezoidal. It should be noted that the cross-sectional shapes of the slider 13 and the first groove listed above are merely examples, and this application does not limit the specific shape of the cross-section of the slider 13 and the first groove.

[0047] In some optional embodiments, the cross-sections of the connecting block 14 and the second groove can be flat rectangular or trapezoidal structures. It should be noted that the cross-sectional shapes of the connecting block 14 and the second groove 111 listed above are merely examples, and this application does not limit the specific shapes of the cross-sections of the connecting block 14 and the second groove 111.

[0048] Please combine Figure 2 In some embodiments, the extension direction of the slide 111 is the width direction of the tray 11. A limiting hole 112 is provided on the groove wall of the slide 111. The door 12 also includes a limiting block 131. The limiting block 131 extends movably into the limiting hole 112 and is connected to the slider 13. The limiting block 131 is used to limit the floating distance of the door 12 in the width direction of the tray 11.

[0049] Thus, the door 12 is slidably connected to the slide groove 111 via the slider 13, allowing the door 12 to float in the width direction of the tray 11 to adapt to the installation position of the electronic device notch. The limiting hole 112 on the side wall of the slide groove 111 engages with the limiting block 131 of the door 12. When the door 12 moves laterally, the range of motion of the limiting block 131 within the limiting hole 112 is restricted, thereby precisely controlling the lateral displacement of the door 12 relative to the tray 11. The connection between the slider 13 and the limiting block 131 further ensures that the door 12 maintains its linkage with the tray 11 during floating, preventing uneven gaps or insertion failure due to excessive offset.

[0050] In some embodiments, the limiting block 131 is made of an elastic material, such as rubber; during the assembly of the card tray, the limiting block 131 abuts against the groove wall of the slide 111 and undergoes elastic compression deformation; when the card tray is fully assembled, the limiting block 131 is inserted into the limiting hole 112 and returns to its original state.

[0051] Thus, during the assembly of the card holder, when the door 12 moves along the slide groove 111 via the slider 13, the limiting block 131 contacts and is squeezed against the groove wall of the slide groove 111. The elastic material allows the limiting block 131 to undergo compressive deformation, thereby reducing the frictional resistance with the groove wall and facilitating the sliding of the door 12 to the target position. When the door 12 moves to the position corresponding to the limiting hole 112, the external force on the limiting block 131 is released, and the elastic restoring force drives it to restore its initial shape and extend into the limiting hole 112, thereby achieving stable limitation of the floating distance of the door 12.

[0052] In some embodiments, when the limiting block 131 extends into the limiting hole 112, the limiting block 131 can, through its own elasticity, both ensure the floating ability of the door 12 and prevent the door 12 from falling off; or, when the limiting block 131 extends into the limiting hole 112, the size of the limiting hole 112 is larger than the size of the limiting block 131, so that the structure of the limiting block 131 can both ensure the floating ability of the door 12 and prevent the door 12 from falling off.

[0053] Please combine Figure 2 In some embodiments, the extension direction of the slide 111 is the width direction of the tray 11, and the slider 13 is provided with a first protrusion 132 in the length direction of the tray 11. The first protrusion 132 is used to limit the floating distance of the door 12 in the length direction of the tray 11.

[0054] Thus, the first protrusion 132 on the slider 13, through its contact with the sidewall of the groove 111, restricts the displacement of the door portion 12 in the length direction within a preset range. When the card holder is inserted into the electronic device, the floating of the door portion 12 in the width direction can adapt to the notch position deviation, while the first protrusion 132 prevents the door portion 12 from moving excessively in the length direction, avoiding misalignment between the door portion 12 and the notch, which would prevent it from being inserted.

[0055] Please combine Figure 2 In some embodiments, the extension direction of the slide 111 is the width direction of the tray 11, and the connecting block 14 is provided with a second protrusion 133 in the thickness direction of the tray 11. The second protrusion 133 is used to limit the floating distance of the door portion 12 in the thickness direction of the tray 11.

[0056] Thus, when the door portion 12 is subjected to external assembly pressure, the connecting block 14 moves along the width direction of the slide groove 111 to achieve position adjustment. At this time, the gap between the second protrusion 133 and the side wall of the slide groove 111 determines the maximum allowable displacement in the thickness direction. When the door portion 12 tends to shift in the thickness direction, the second protrusion 133 will abut against the inner wall of the slide groove 111 to form a rigid block, thereby limiting the displacement in the thickness direction within a predetermined range.

[0057] In some embodiments, this application also provides an electronic device including the card tray described above. The card tray includes a tray 11 and a door 12; the door 12 is located at one end of the tray 11 in the longitudinal direction, and the door 12 is buoyantly connected to the tray 11 to adjust the position of the door 12 relative to the tray 11. The card tray carries electronic cards through the tray 11; wherein, the end of the tray 11 in the longitudinal direction is the end point when the tray 11 is inserted into the electronic device.

[0058] Thus, when the card tray is inserted into the electronic device, the door portion 12, under the action of the floating connection structure, can be finely adjusted along the length, width, or thickness direction according to the actual position of the frame notch. For example, if there is a deviation in the connector installation position, the door portion 12 generates adaptive displacement through the clearance fit between the slide groove 111 and the slider 13, eliminating misalignment interference caused by manufacturing tolerances. The tray 11 serves as a guide reference, guiding the electronic card to maintain stable contact with the connector during insertion; at the same time, the door portion 12 aligns with the notch through adaptive floating until it moves into the notch to seal it; therefore, the door portion 12 can achieve dynamic adjustment through floating, ensuring assembly accuracy and simplifying the installation process.

[0059] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
