Description

Technical Field

[0001] The present application relates to the field of key technology, and in particular to electronic equipment. Background Art

[0002] Electronic devices, such as mobile phones, tablet computers or bracelets, all include carriers, switches and buttons. The switch is installed on the carrier. For mobile phones, the carrier can be the middle frame. Press the button to make the conductive base of the button click on the switch to realize the switch function. Therefore, the tolerance chain that affects the feel of button pressing involves at least carriers, switches and buttons, etc. If the size fluctuation of any one of them is large, it will cause the button to feel weak (pressing virtual position) or overpressure (cannot press).

[0003] In order to solve the above problems, the commonly used technical means is to prevent overpressure by pasting auxiliary materials to fill the empty spaces or grinding off part of the structure. Filling the empty spaces or grinding requires multiple debugging (for example, it is necessary to adjust the fillers that fill the empty spaces or grind them multiple times until the hand feel is not weak or the pressure is not too high). Therefore, a large amount of debugging work is required to adjust the hand feel, which is inefficient. Furthermore, the above technical means have high requirements on the processing capability of the structural parts (at least one of the load-bearing parts, switches and buttons). In this way, less grinding or easier filling of the empty spaces can be avoided. Of course, even if the processing capability of the aforementioned structural parts is high and the precision of the structural parts is high, it is still necessary to fill the empty spaces or grind off part of the structure in some cases. Utility Model Content

[0004] The purpose of the present application is to disclose an electronic device that has a small workload for adjusting the feel of keystrokes, high efficiency and low requirements on the processing capability of structural parts.

[0005] The present application discloses an electronic device. The electronic device comprises a carrier, a key, a switch and a gap adjustment component. The key comprises a conductive base. The switch is movably assembled with the carrier, the gap adjustment component supports the switch, and when an external force is applied, pushes the switch to move forward or backward relative to the conductive base, so that the gap between the switch and the conductive base is reduced or increased accordingly; when no external force is applied, the gap adjustment component keeps the switch and the conductive base at the adjusted gap.

[0006] In some embodiments, the gap adjustment component is connected to the switch via a spiral structure; the gap adjustment component generates a rotational motion, and the spiral structure converts the rotational motion into a linear motion of the switch moving forward or backward.

[0007] In some embodiments, the gap adjustment assembly includes a pusher, and the pusher is connected to the switch via the spiral structure; the spiral structure is a thread.

[0008] In some embodiments, the electronic device includes an FPC component movably assembled on the carrier, the switch is assembled on the FPC component, the pushing member is threadedly connected to the FPC component, and the FPC component moves synchronously with the switch.

[0009] In some embodiments, the FPC assembly includes a flexible circuit board and a reinforcement plate, the switch is electrically connected to the flexible circuit board; the flexible circuit board is fixed to the reinforcement plate; the reinforcement plate is provided with a screw hole, and the pusher is threadedly connected to the screw hole.

[0010] In some embodiments, the pushing member is magnetic.

[0011] In some embodiments, the bearing member is provided with a mounting groove, and the gap adjustment assembly is located in the mounting groove.

[0012] In some embodiments, the gap adjustment assembly includes a pushing member and an elastic member for realizing the forward or backward movement of the switch; the elastic member is connected to the pushing member and the supporting member, and deforms with the movement of the pushing member to press against the pushing member, so that the switch and the conductive base maintain the adjusted gap.

[0013] In some embodiments, the elastic member is a spring sheet, comprising a mounting portion, an arc-shaped portion and a contact arm. The mounting portion is connected to the carrier. The arc-shaped portion comprises a first end and a second end opposite to each other, and the first end is connected to the mounting portion. The contact arm and the mounting portion are located on the same side of the arc-shaped portion, and comprise a connecting arm connected to the second end and an abutting arm abutting against the pushing member; the connecting arm is inclined toward the mounting portion, and the abutting arm is upwardly tilted relative to the mounting portion.

[0014] In some embodiments, the button is located on a peripheral side of the electronic device, and the pressing direction of the button and the moving direction of the switch are both perpendicular to the thickness direction of the electronic device.

[0015] For the electronic device, when the feel of the key is weak or over-pressured, the feel is adjusted by adjusting the gap between the conductive base of the key and the switch through the gap adjustment component, so that the feel will not be over-pressured or weak. It is only necessary to move the switch forward or backward without pasting auxiliary materials to fill the empty space or grinding off part of the structure to prevent over-pressure and other large-scale debugging work (filling the empty space or grinding requires multiple debuggings, because if the feel is still weak or over-pressured, it is necessary to continue to correct the filling parts or grind the structure again until the feel is not weak or over-pressured), so the workload is small and the efficiency is high. In addition, because it is only necessary to move the switch forward or backward relative to the conductive base, the process capability requirements for related structural parts (conductive base, switch or bearing member, in subsequent implementations, even including FPC components) are low, and structural parts with a larger tolerance range can be assembled and adapted, which improves processing efficiency and reduces loss costs, because the tolerance range can be compensated by the gap of the forward or backward movement.

[0025] In order to solve the problems of large workload, low efficiency and high process capability requirements for key feel adjustment, the inventor of the present application has come up with the idea that when the key feel is weak or over-pressurized, the gap between the switch and the conductive base of the key is adjusted, thereby adjusting the feel so that the feel is not too weak or over-pressurized. For example, when the feel is weak, the gap is reduced, and when the feel is over-pressurized, the gap is increased. The electronic device of the present application is described below in conjunction with the relevant drawings.

[0026] Figure 1 and Figure 2 The electronic device is shown as a mobile phone, but is not limited thereto. The electronic device can be a 3C product such as a wristband or a tablet computer. Figure 1 and Figure 2 The button is shown as being located on the side of the electronic device (also referred to as a lateral button in the industry), but in other embodiments, the button may also be located on the front of the electronic device, etc. The front is the surface facing the consumer when the consumer uses the electronic device. Of course, for the aforementioned adjustment gap, the position of the button is not limited, as long as the consumer can press it.

[0027] See also Figure 3 , Figure 5 and Figure 6 Combined with Figure 1 , Figure 2 and Figure 4 , the present application discloses an electronic device. The electronic device includes a carrier 1, a button 2, a switch 3 and a gap adjustment component 4. The structure of the carrier 1 is not limited, at least it serves as a mounting carrier for the switch 3. In an embodiment of the present application, the electronic device is a mobile phone, and the carrier 1 is a middle frame. In other embodiments, the button 2 and the gap adjustment component 4 can also be assembled to the carrier 1. The button 2 includes a conductive base 21. In an embodiment of the present application, the conductive base 21 of the button 2 is assembled to the button body 22. The consumer applies a force to the button body 22 to press the button 2, so that the conductive base 21 clicks the switch 3.

[0028] The switch 3 is assembled with the carrier 1 movably. The movably assembled is not limited to the assembly through the FPC (Flexible Printed Circuit) assembly 5 as described later. It can also be assembled directly, and the switch 3 can be moved forward or backward toward the conductive base 21 as described later. The gap adjustment assembly 4 supports the switch 3, and when the external force is adjusted, it pushes the switch 3 to move forward toward the conductive base 21, that is, the gap between the switch 3 and the conductive base 21 is reduced, or retreats relative to the conductive base 21, that is, the gap between the switch 3 and the conductive base 21 is increased. In this way, the gap between the switch 3 and the conductive base 21 is adjusted by moving the switch 3 forward or backward. When the gap is appropriate (that is, the hand feel is not weak and the pressure is over), no external force is applied to the gap adjustment assembly, that is, when no external force is applied, the gap adjustment assembly keeps the switch 3 and the conductive base 21 at the adjusted gap. As for the gap adjustment assembly 4, it is not limited to the composition and / or structure as described later, and it can achieve the above-mentioned effect.

[0029] As set up above, when the feel of the button 2 is weak or over-pressurized, the gap between the conductive base 21 of the button 2 and the switch 3 is reduced or increased by applying external force to the gap adjustment component 4, and when no external force is applied, the gap is maintained at the adjusted gap, thereby adjusting the feel so that the feel will not be weak or over-pressurized. It is only necessary to move the switch 3 forward or backward without the need to paste auxiliary materials to fill in the empty space or grind off part of the structure to prevent over-pressurization and other large-scale debugging work (filling in the empty space or grinding requires multiple debuggings, because if the feel is still weak or over-pressurized, it is necessary to continue to correct the filling parts or grind the structure again until the feel is not weak or over-pressurized). Therefore, the workload is small and the efficiency is high. In addition, because the switch 3 only needs to be moved forward or backward relative to the conductive base 21, the process capability requirements for related structural parts (conductive base 21, switch 3 or carrier 1, and in subsequent embodiments, even including FPC assembly 5) are low, and structural parts with a larger tolerance range can be assembled and adapted, thereby improving processing efficiency and reducing loss costs, because the tolerance range can be compensated by the gap of the forward or backward movement. For example, in some cases, if the tolerance is large, the gap for the movement of the switch 3 is large, and if the tolerance is small, the gap for the movement of the switch 3 is small, thereby compensating for the tolerance.

[0030] In some embodiments, the gap adjustment component 4 is connected to the switch 3 via a spiral structure. The gap adjustment component 4 generates a rotational motion, and the spiral structure converts the rotational motion into a linear motion of the switch 3 moving forward or backward. The structure of the spiral structure is not limited, for example, a cam structure, a structure composed of a gear and a rack, a lead screw and a nut, a guide rail and a slider, etc.

[0031] As set up above, since the gap adjustment component 4 is connected to the switch 3 through a spiral structure, the rotational motion can be converted into a linear motion of the switch 3 moving forward or backward relative to the conductive base 21. Since only the relevant parts of the gap adjustment component 4 need to be rotated to generate the rotational motion, the efficiency of adjusting the feel is higher, the workload is smaller, and the process requirements for the structural parts are lower.

[0032] See also Figure 5 and Figure 6 Combined with Figure 3 , the gap adjustment component 4 includes a pusher 41, and the pusher 41 is connected to the switch 3 through the spiral structure; the spiral structure is a thread. In this case, the pusher 41 can be a bolt. Of course, in some embodiments, the pusher 41 and the switch 3 can be directly threadedly connected, for example, the pusher 41 is provided with an external thread, and the switch 3 is provided with an internal thread. The internal thread and the external thread constitute the spiral structure, and this method can be called a direct connection. In other embodiments, the pusher 41 and the switch 3 can also be indirectly connected, for example, the indirect connection is subsequently achieved through the FPC component 5.

[0033] As configured above, the switch 3 can be moved forward or backward relative to the conductive base 21 only by rotating the pusher 41. In this way, the efficiency of adjusting the feel is higher, the workload is smaller, and the process capability requirements for the structural parts are lower.

[0034] See also Figure 6 , an implementation method for adjusting the relationship between the gap and the feel is described as follows:

[0035] When the hand feel is weak, it is necessary to reduce the gap between the conductive base 21 and the switch 3. At this time, the pusher 41 is unscrewed (the pusher 41 moves along the arrow e), and the overall size of the switch 3 and the pusher 41 increases. Then, the gap adjustment component 4 will make the switch 3 (in subsequent implementations, the overall size of the switch 3, the pusher 41 and the FPC component 5 increases) move along the direction of arrow E toward the conductive base 21 (in subsequent implementations, the increase in size will cause the elastic force of the elastic member 42 to push the switch 3 forward toward the conductive base 21), thereby reducing the gap between the conductive base 21 and the switch 3.

[0036] When the hand feels overpressure, it is necessary to increase the gap between the conductive base 21 and the switch 3. At this time, the pusher 41 is screwed in (the pusher 41 moves along the arrow E), the size of the switch 3 and the pusher 41 is reduced (in subsequent embodiments, the overall size of the switch 3, the pusher 41 and the FPC assembly 5 is reduced), and the gap adjustment assembly 4 makes the switch 3 retreat relative to the conductive base 21 (in subsequent embodiments, the size reduction exerts a force on the elastic member 42 in the direction of the arrow E, but the reaction force of the elastic member 42 pulls the switch 3 back in the direction of the arrow e), thereby, the switch 3 retreats relative to the conductive base 21, increasing the gap between the conductive base 21 and the switch 3.

[0037] See 5 and Figure 6 Combined with Figure 3 The electronic device includes an FPC assembly 5 movably assembled on the carrier 1. The movably assembled means that the FPC assembly 5 can move synchronously with the switch 3 as described later, so there is no limit to how the movably assembled. Figure 6 and Figure 5 and with Figure 3 In comparison, the carrier 1 includes a receiving groove. The FPC assembly 5 is located in the receiving groove. The switch 3 is assembled to the FPC assembly 5, and the pusher 41 is threadedly connected to the FPC assembly 5, so that the FPC assembly 5 and the switch 3 move synchronously, that is, when the switch 3 moves forward relative to the conductive base 21, the FPC assembly 5 also moves forward relative to the conductive base 21, and when the switch 3 moves backward relative to the conductive base 21, the FPC assembly 5 also moves backward relative to the conductive base 21.

[0038] As set up above, since the flexible circuit board 51 (FPC) of the FPC assembly 5 needs to be electrically connected to the switch 3, and since the FPC assembly 5 moves synchronously with the switch 3, compared with moving the switch 3 alone, the connection between the switch 3 and the flexible circuit board 51 can be prevented from loosening, thereby improving reliability.

[0039] See also Figure 3 and Figure 6 Combined with Figure 5 The FPC assembly 5 includes a flexible printed circuit (FPC) 51 and a reinforcing plate 52. The switch 3 is electrically connected to the flexible printed circuit 51; the flexible printed circuit 51 is fixed to the reinforcing plate 52. There is no limit to how to fix it. In the embodiment of the present application, the flexible printed circuit 51 is fixed to the reinforcing plate 52 by means of adhesive 53. The reinforcing plate 52 is provided with a screw hole 521, and the pusher 41 is threadedly connected to the screw hole 521.

[0040] As configured above, the reinforcing plate 52 enhances the strength of the flexible circuit board 51 , making it easier for the pusher 41 to be threadedly connected to the switch 3 , and the connection is more reliable.

[0041] In some embodiments, the pusher 41 is magnetic. In this way, by manipulating the magnetic controller outside the electronic device, the polarity of the magnetic controller is opposite to the polarity of the pusher 41, so that according to the principle that like attracts like and opposites repel each other, the pusher 41 can be quickly rotated in and out (that is, the gap adjustment component 4 is subjected to external force by the magnetic controller). Of course, in other embodiments, the pusher 41 may not be magnetic. In this case, for example, it may be necessary to first disassemble the electronic device, and then rotate the pusher 41 in or out to achieve the corresponding forward or backward movement of the switch 3 relative to the conductive base 21.

[0042] As set up as above, since the pushing member 41 is magnetic, when the feel needs to be adjusted, there is no need to disassemble the electronic device. It is only necessary to control the magnetic controller outside the electronic device, and the magnetism can be used to realize the rapid rotation in and out of the pushing member 41, which makes it more convenient to adjust the feel, more efficient to adjust the feel, less workload, and lower process requirements for structural parts.

[0043] See also Figure 6 Combined with Figure 5 The carrier 1 is provided with a mounting groove 11. The gap adjustment component 4 is located in the mounting groove 11. In the subsequent case where the electronic device includes an FPC component 5, the FPC component 5 covers the mounting groove 11.

[0044] As configured above, since the gap adjustment component 4 is located in the installation groove 11, it can be understood that the gap adjustment component 4 is hidden inside the electronic device, saving space for installing the gap adjustment component 4, which is beneficial to the appearance and miniaturization of the electronic device.

[0045] See also Figure 6 Combined with Figure 5 and Figure 3 The gap adjustment component 4 includes a pusher 41 and an elastic member 42 for realizing the forward or backward movement of the switch 3. The elastic member 42 is connected to the pusher 41 and the carrier 1, and deforms with the movement of the pusher 41 to press against the pusher 41, so that the switch 3 and the conductive base 21 are kept at the adjusted gap. Based on the function of the elastic member 42, the structure of the elastic member 42 is not limited, and can be a spring, or a spring, etc., as long as it can be deformed.

[0046] As described above, due to the elastic force of the elastic member 42 , the elastic member 42 presses against the pushing member 41 , and thus the pushing member 41 will not be rotated out. Finally, the switch 3 and the conductive base 21 can be reliably maintained at the adjusted gap.

[0047] See also Figure 7 Combined with Figure 6 , the elastic member 42 is a spring sheet, including a mounting portion 421, an arc portion 422 and a contact arm 423. The mounting portion 421 is connected to the carrier 1. The arc portion 422 includes a first end and a second end opposite to each other. The first end is connected to the mounting portion 421. The contact arm 423 and the mounting portion 421 are located on the same side of the arc portion 422, and include a connecting arm 4231 connected to the second end and an abutting arm 4232 abutting against the pusher 41. In this embodiment, the contact arm 423 pushes the switch 3 and the pusher 41 (or the switch 3, the pusher 41 and the FPC assembly 5) forward or makes the switch 3 and the pusher 41 retreat (i.e., pulls back the switch 3, the pusher 41 and the FPC assembly 5). The connecting arm 4231 is inclined toward the mounting portion, and the abutting arm 4232 is tilted upward relative to the mounting portion 421, so that the connecting arm 4231 and the abutting arm 4232 form an obtuse angle.

[0048] As described above, since the arc-shaped portion 422 is connected to the mounting portion 421, the connecting arm 4231 is connected to the second end of the arc-shaped portion 422 and tilted toward the mounting portion 421, and the abutting arm 4232 is tilted upward relative to the mounting portion 421, the elastic member 42 of this structure has better elasticity, which can better prevent the pusher 41 from being screwed out, and ensure that the switch 3 and the conductive base 21 are reliably maintained at the adjusted gap. Of course, in some cases, the elastic member 42 can better abut the pusher, and when the pusher 41 is screwed out, the screwing amount of the pusher 41 can be converted into the adjusted gap of the switch 3 as much as possible, and will not be converted into the deformation amount of the elastic member 42.

[0049] See also Figure 2 Combined with Figure 1 , the button 2 is located at the side of the electronic device, that is, the button 2 is a lateral button. Figure 2 , Figure 1 and Figure 5 It can be seen that the pressing direction of the button 2 and the moving direction of the switch 3 are both perpendicular to the thickness direction of the electronic device. Figure 1 and Figure 5 Indicates the pressing direction C of button 2. Figure 2 The thickness direction c of the electronic device is shown. Direction C is perpendicular to direction c.

[0050] As described above, the movement direction of the switch 3 is perpendicular to the thickness direction of the electronic device through the gap adjustment component 4, and the movement direction of the switch 3 is the same as the movement direction of the key 2. The above scheme is more convenient for adjusting the feel of the key 2 when it is set on the side of the electronic device. Because the key 2 is located on the side of the electronic device, it is not convenient to paste auxiliary materials or grind off part of the structure, etc., thereby ensuring small workload, high efficiency and low requirements on the process capability of the structural parts.

[0051] The above description is only a preferred implementation mode of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
