Detailed ways

In order to make the objectives, technical solutions, and advantages of the present disclosure clearer, the technical solutions of the present disclosure will be described clearly and completely in conjunction with specific embodiments of the present disclosure and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present disclosure.

The technical solutions disclosed in each embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings.

As shown in Figures 1 to 3, the embodiments of the present disclosure disclose a mobile terminal. The mobile terminal may specifically include a housing 100, a main board 200, a tray 300, a tray holder 400, a tray push rod 500, and a reset button 600. .

The housing 100 is an installation basis for most parts included in the mobile terminal, and the housing 100 may specifically include a frame. The housing 100 is provided with a card taking hole 110 and a card holder hole 120, and the card taking hole 110 and the card holder hole 120 can be specifically opened on the frame. The main board 200 is disposed in the housing 100, and the main board 200 can control the working state of the components included in the mobile terminal.

The card holder 400 is disposed in the housing 100, and the card holder 400 is connected to the main board 200. The card tray 300 can enter and exit the housing 100 through the card tray hole 120. After the card is installed on the card tray 300, the card tray 300 can be pushed into the housing 100. At this time, the card can interact with the main board 200 under the action of the card tray holder 400. The upper card socket cooperates to be electrically connected to the main board 200. The card tray push rod 500 is disposed in the housing 100, and the card tray 300 can be ejected from the housing 100 through the card tray push rod 500. Specifically, the card holder push rod 500 is provided with a force receiving portion 510, and a side of the force receiving portion 510 facing away from the card removal hole 110 is provided with a protruding portion. When the user needs to take out the card, a needle tool can be inserted into the card taking hole 110. The needle tool can contact the force receiving part 510 and apply a force to the force receiving part 510, so that the card holder push rod 500 faces the card holder 300. When a pushing force is applied, the card holder 300 ejects the housing 100 through the card holder hole 120 under the effect of the pushing force, and the user can take out the card. Optionally, the mobile terminal may further include a card removal needle 700, which can be used as the aforementioned needle tool.

When the mobile terminal crashes during use, the reset key 600 can be used to implement forced shutdown of the mobile terminal, so that the mobile terminal can be reset. The reset button 600 can be arranged in the housing 100, and the reset button 600 is arranged opposite to the protruding part of the force receiving part 510. When the force receiving part 510 is stressed, the entire card push rod 500 moves in the housing 100 , So that the protruding portion of the force receiving portion 510 can contact the reset button 600. When the protruding part of the force receiving portion 510 contacts the reset button 600, the reset button 600 can be triggered, thereby realizing the reset operation.

Since the reset button 600 is hidden in the housing 100, the user cannot easily access the reset button 600, so that the reset button 600 is not easily triggered by mistake. Therefore, the mobile terminal will not fail to work normally because the reset button 600 is triggered by mistake. At the same time, after the reset button 600 adopts the hidden setting mode, the appearance of the mobile terminal is more concise, and the appearance and texture of the mobile terminal is better. In addition, if the reset button 600 is not provided on the exterior of the mobile terminal, dust, liquids and other substances in the external environment will not enter the interior of the mobile terminal through the gap between the reset button 600 and the housing 100, thereby better protecting the mobile terminal. terminal.

In addition, when the force receiving portion 510 contacts the reset button 600 through the protrusion to trigger the reset button 600, the force receiving portion 510 can more reliably apply a force to the reset button 600, making the trigger operation of the reset button 600 easier to implement.

It should be noted that when the reset button 600 is triggered, the card tray 300 will generally pop up relative to the housing 100. However, since the frequency of resetting of the mobile terminal is not high, the card tray 300 is also Being popped up will not cause the operating experience of the mobile terminal to deteriorate. In addition, when the card tray 300 only needs to be ejected without triggering the reset button 600, since the card removal operation takes a relatively short time, the time for the force receiving part 510 to contact the reset button 600 (generally 1 to 3 seconds) It is shorter than the time (for example, 10 seconds) that the force receiving part 510 contacts the reset button 600 when the reset button 600 is triggered. Therefore, in this case, the reset button 600 will not be triggered and the mobile terminal will not be reset. Under the circumstances, the normal use of the mobile terminal will not be affected.

In an optional embodiment, in order to simplify the structure of the reset key 600, the reset key 600 may specifically include a first conductive portion 610 and a second conductive portion 620, and the first conductive portion 610 and the second conductive portion 620 are connected to each other. The portions 620 are electrically connected to the motherboard 200, and there is an isolation portion between the first conductive portion 610 and the second conductive portion 620, so that the first conductive portion 610 and the second conductive portion 620 are not directly connected. When the force receiving portion 510 is in contact with the reset key 600, the first conducting portion 610 and the second conducting portion 620 are electrically conducted through the force receiving portion 510.

When the reset key 600 includes the first conductive portion 610 and the second conductive portion 620 described above, the number of the protrusions can be set to at least two, including the first protrusion 512 and the second protrusion 513. When the force receiving portion 510 is in contact with the reset key 600, the first conducting portion 610 is in contact with the first protruding portion 512, and the second conducting portion 620 is in contact with the second protruding portion 513, so that the first conducting portion The 610 and the second conducting portion 620 are electrically connected through the force receiving portion 510. Compared with the embodiment in which only one protruding portion is provided, the first protruding portion 512 and the second protruding portion 513 can contact the first conducting portion 610 and the second conducting portion 620 independently, so that the first When the protrusion 512 is in contact with the first conductive portion 610 and the second protrusion 513 is in contact with the second conductive portion 620, the reliability is higher.

In an alternative embodiment, the reset button 600 further includes a switching circuit board 630, the first conducting portion 610 and the second conducting portion 620 are both disposed on the switching circuit board 630, the first conducting portion 610 and The second conducting portion 620 is electrically connected to the main board 200 through the switching circuit board 630. Optionally, the switching circuit board 630 may be a flexible circuit board. With this structure, the location of the first conductive portion 610 and the second conductive portion 620 is not limited by the position of the main board 200, so the positions of the first conductive portion 610 and the second conductive portion 620 can be flexibly set. To facilitate the structural design of the mobile terminal.

Further, in order to simplify the structure of the first conductive portion 610 and the second conductive portion 620, and at the same time improve the contact reliability between the first conductive portion 610 and the second conductive portion 620 and the force receiving portion 510, the first conductive portion At least one of the through portion 610 and the second conductive portion 620 has a golden finger structure. Optionally, the first conductive portion 610 and the second conductive portion 620 are both gold finger structures. The golden finger structure here has the advantages of strong oxidation resistance and strong conductivity, so that the electrical connection between the reset button 600 and the main board 200 is more reliable, and the first conductive portion 610 and the second conductive portion 620 are extended. Life.

As shown in FIGS. 4-8, in another alternative embodiment, the main board 200 is provided with a first conductive elastic piece 810 and a second conductive elastic piece 810 on the side facing the first conductive portion 610 and the second conductive portion 620. The conductive elastic sheet 820, optionally, the first conductive elastic sheet 810 and the second conductive elastic sheet 820 may be arranged on the main board 200 through a mounting process. The first conducting portion 610 is electrically connected to the main board 200 through a first conducting elastic piece 810, and the second conducting portion 620 is electrically connected to the main board 200 through a second conducting elastic piece 820. The first conductive elastic piece 810 and the second conductive elastic piece 820 are directly arranged on the main board 200, the first conductive portion 610 is arranged close to the first conductive elastic piece 810, and the second conductive portion 620 is arranged adjacent to the second conductive elastic piece 820. Therefore, the reset button 600 does not need to be electrically connected to the main board 200 through the transfer circuit board 630, so the transfer circuit board 630 can be omitted in this embodiment, so that the reset button 600 has a simpler structure and lower cost. In addition, the first conductive elastic piece 810 and the second conductive elastic piece 820 have certain elasticity, the first conductive portion 610 can press the first conductive elastic piece 810, and the second conductive portion 620 can press the second conductive elastic piece 820. The first conductive elastic piece 810 and the second conductive elastic piece 820 can be appropriately deformed, and the first conductive portion 610 and the first conductive elastic piece 810, and the second conductive portion 620 and the second conductive elastic piece 820 are more reliably contacted. Therefore, the reliability of electrical connection between the first conductive portion 610 and the second conductive portion 620 and the motherboard 200 is improved.

In order to improve the position accuracy of the first conductive portion 610 or the second conductive portion 620 in the housing 100, and at the same time make the structure of the mobile terminal more compact, at least one of the first conductive portion 610 and the second conductive portion 620 The first conductive portion 610 and the second conductive portion 620 are insulated from the housing 100. At this time, the aforementioned isolation part may be a part of the housing 100, or may be a structure provided separately.

Further, both the first conductive portion 610 and the second conductive portion 620 are integrally formed with the housing 100. For example, the first conductive portion 610, the second conductive portion 620, and the housing 100 may be formed by an integral injection molding process. On the one hand, this structure can simplify the processing technology of the mobile terminal, and on the other hand, it can further improve the position accuracy of the first conductive portion 610 and the second conductive portion 620 in the housing 100. At this time, the aforementioned isolation part is a part of the housing 100.

In an alternative embodiment, the card holder push rod 500 is movably arranged in the housing 100, or the card holder push rod 500 is rotatably arranged in the housing 100. In contrast, when the former setting method is adopted, the card holder push rod 500 can move relative to the reset button 600 after being forced, and then approach the reset button 600 and contact the reset button 600. At this time, the force receiving portion 510 may be arranged opposite to the reset button 600 along the axis of the card removal hole 110, and the distribution of the two is more compact, thereby improving the utilization of the space in the mobile terminal. In addition, when the reset button 600 includes the first conductive portion 610 and the second conductive portion 620, the movement of the card holder push rod 500 relative to the housing 100 is more conducive to the force receiving portion 510 being more reliably and simultaneously with the first conductive portion. 610 is in contact with the second conducting portion 620.

In order to facilitate the removal of the card needle 700 and other tools to more reliably interact with the force receiving portion 510, a groove 511 may be provided on the side of the force receiving portion 510 facing the card removal hole 110, and the end of the tool such as the removal needle 700 can act on At the groove 511, the card holder push rod 500 is pushed to move. If the groove 511 and the protruding part are aligned in the axial direction of the card removal hole 110, the structural strength of the protruding part will be low, causing the stressed part 510 to easily crack or even break. Therefore, the groove 511 and the protrusion can be arranged in a staggered manner, so that there is a certain distance between the groove 511 and the protrusion, so as to ensure the structural strength of the force receiving portion 510.

Further, the force receiving portion 510 may be arranged in a strip structure, and the extension direction of the force receiving portion 510 is parallel to the main board 200 (that is, the extension direction of the force receiving portion 510 is parallel to the plane where the main board 200 is located) and perpendicular to the card removal hole In the axial direction of 110, the aforementioned grooves 511 and protrusions are arranged along the extension direction of the force receiving portion 510. Such a force receiving portion 510 can utilize the spatial arrangement of the mobile terminal in a direction parallel to the main board 200, thereby reducing the space occupied by the force receiving portion 510 in the thickness direction of the mobile terminal, thereby facilitating the ultra-thin mobile terminal Direction development.
