Description

Technical Field

[0001] The invention relates to the field of smart phones, and in particular to a lifting button for smart phones. Background Art

[0002] With the continuous development of smart phones, their functions are becoming more and more extensive. Existing mobile games require multiple button operations, but mobile phones do not have enough buttons to operate games. However, in order to meet the operation requirements of games, people use touch buttons or external game handles (buttons) (fixed to the mobile phone by clips and suction cups); the touch button pressing has no elasticity or any feedback, and it can be said that there is no feel. At the critical moment of the game, it is often wrong to press (press the touch area). Therefore, some mobile game players use external clip-on screen handles to achieve this, which undoubtedly increases the problems of charging, carrying, and installing the handle. If mechanical buttons are directly added at the upper and lower ends, especially the lower end, it is very easy for people to press them by mistake when using the mobile phone normally, or the protrusion affects the appearance and feel, which brings unnecessary trouble to the user. Therefore, it is unreasonable to add mechanical buttons to the mobile phone at this position.

[0003] Therefore, the prior art has defects and needs to be improved. Summary of the invention

[0004] The main purpose of the present invention is to propose a lifting button for a smart phone, aiming to realize the game button function of the smart phone, improve the user's gaming experience, and solve the problem of easy mispressing and affecting the aesthetics.

[0005] To achieve the above-mentioned purpose, the present invention proposes a lifting button for a smart phone, comprising a mobile phone shell, a main control board installed in the shell, at least one button movably and liftably installed on the side of the shell, and a lifting mechanism for driving the button to rise and fall; the lifting mechanism comprises a rotation driving device, the driving end of the rotation driving device is connected to a rotating cam, the rotating cam is provided with a first limiting portion and a second limiting portion for limiting the forward and reverse positions of the rotating cam, and the shell is provided with a limiting boss corresponding to the first limiting portion and the second limiting portion; the outer edge of the rotating cam abuts a support plate, and the support plate is movably connected to the button; a DOME sheet is provided on the side of the support plate corresponding to the button, the button is provided with a pressing boss corresponding to the DOME sheet, and an elastic member is provided between the support plate and the button, and the support plate abuts against the shell through the elastic member along the lifting direction of the button; the DOME sheet and the rotation driving device are both connected to the main control board.

[0006] Preferably, a gap of 0.05-0.1 mm is provided between the DOME sheet and the pressing boss.

[0007] Preferably, the rotation driving device is configured as a motor, a mounting groove for mounting the motor is provided in the housing, and the motor is fixed in the mounting groove by a fixing plate and a locking screw.

[0008] Preferably, the driving end of the rotary drive device is coaxially connected to a rotating shaft, the rotating cam and the rotating shaft are arranged as an integral structure, and brackets for supporting both ends of the rotating shaft are arranged in the housing.

[0009] Preferably, two through holes are symmetrically provided on the support plate, a pull rod screw is respectively passed through the two through holes, and the two pull rod screws respectively pass through the two through holes to be connected with the button.

[0010] Preferably, the elastic member is configured as two springs, the two springs are respectively sleeved on the outside of the two pull rod screws, and one end of the two springs abuts against the support plate, and the other end abuts against the shell.

Different game function buttons can be mapped through software settings, and the sensitivity and rebound effect of the mechanical buttons allow gamers to play more easily. It can provide perfect elastic feel, zero delay, and zero false touch feedback. When entering the game state through software settings, the physical button rises, and the button can be pressed to trigger. When exiting the game, the button automatically returns to the shell and is hidden and cannot be pressed, preventing false presses and damage to the appearance. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] This embodiment proposes a lifting type button for a smart phone, referring to Figure 1 and Figure 2 , comprising a mobile phone housing 1, a main control board 2 is installed in the housing 1, and at least one button 3 is installed on the side of the housing 1, and a lifting mechanism 4 is used to drive the button 3 to rise and fall; the lifting mechanism 4 comprises a rotating driving device 41, the driving end of the rotating driving device 41 is connected to a rotating cam 42, and the rotating cam 42 is provided with a first limiting portion 421 and a second limiting portion 422 for limiting the forward and reverse positions of the rotating cam 42, and the housing 1 is provided with limiting portions corresponding to the first limiting portion 421 and the second limiting portion 422. The outer edge of the rotating cam 42 abuts against a support plate 43, and the support plate 43 is movably connected to the button 3; a DOME sheet 5 is provided on the side of the support plate 43 corresponding to the button 3, and a pressing boss 31 corresponding to the DOME sheet 5 is provided on the button 3, and an elastic member 46 is provided between the support plate 43 and the button 3, and the support plate 43 abuts against the shell 1 through the elastic member 46 along the lifting direction of the button 3; the DOME sheet 5 and the rotating drive device 41 are both connected to the main control board 2.

[0024] Furthermore, the rotation drive device 41 is configured as a motor, and a mounting slot 12 for mounting the motor is provided in the housing 1, and the motor is fixed in the mounting slot 12 by a fixing plate 13 with a screw. The driving end of the rotation drive device 41 is coaxially connected to a rotating shaft 44, the rotating cam 42 and the rotating shaft 44 are configured as an integral structure, and a bracket 14 for supporting both ends of the rotating shaft 44 is provided in the housing 1. Two through holes 431 are symmetrically provided on the support plate 43, and a pull rod screw 45 is respectively passed through the two through holes 431, and the two pull rod screws 45 respectively pass through the two through holes 431 to be connected to the button 3. There is a gap between the pull rod screw 45 and the two through holes 431 for movement. Reference Figure 5 The elastic member 46 is configured as two springs, and the two springs are respectively sleeved on the outside of the two pull rod screws 45 , and one end of the two springs abuts against the support plate 43 , and the other end abuts against the shell 1 .

[0025] It should be noted that when installing, refer to Figure 3 , install the rotating shaft 44 coaxially on the driving end of the motor, then put the motor into the installation slot 12, and screw the fixing plate 13 to the installation slot 12 to fix the motor. At this time, the two ends of the rotating shaft 44 are just mounted on the two brackets 14, and a limiting boss 11 is provided between the two brackets 14, which is used to abut against the first limiting portion 421 and the second limiting portion 422 of the rotating cam 42 to limit the forward and reverse rotation of the rotating cam 42. Then install the DOME sheet 5 on the side of the support plate 43 close to the button 3, pass the pull rod screw 45 through the two through holes 431 of the support plate 43, and insert a spring on the pull rod screw 45. It should be noted that there is a gap between the pull rod screw 45 and the support plate 43, so as to facilitate the pull rod screw 45 to move and retract in the through hole 431.

[0026] Then the button 3 is inserted from the outside of the shell 1, and a screw hole corresponding to the pull rod screw 45 is provided on the button 3, so that the end of the pull rod screw 45 is connected to the button 3. When the end of the button 3 is completely accommodated in the side of the shell 1 and flush with the side, the side of the support plate 43 away from the button 3 abuts against the rotating cam 42. At this time, the first limiting portion 421 of the rotating cam 42 abuts against the first limiting plane 111 of the limiting boss 11, and at this time, the two ends of the spring respectively abut against the side of the support plate 43 close to the button 3 and the inner side of the shell 1. The spring is compressed, giving the support plate 43 a force toward the inside of the shell 1. The force is transmitted to the pull rod screw 45 via the support plate 43, and then transmitted to the button 3 via the pull rod screw 45, thereby tightening the button 3 in the shell 1 to prevent it from protruding from the surface of the shell 1.

[0027] When the user is playing a game and needs the button 3 to extend out of the surface of the housing 1, refer to Figure 4, the main control board 2 controls the motor to rotate clockwise, and the motor drives the rotating shaft 44 to rotate, so that the rotating cam 42 pushes the support plate 43 out along the direction of the key 3 extending, and the spring is compressed. At this time, the DOME sheet 5 installed on one side of the support plate 43 will give the pressing boss 31 of the key 3 a force to extend as the support plate 43 is pushed out, thereby pushing the key 3 out. When the rotating cam 42 rotates to the point where its second limiting portion 422 abuts against the second limiting plane 112 of the limiting boss 11, the motor stops rotating due to resistance, so that the key 3 extends to the target position. At this time, the motor stops outputting torque when the power is turned off, and the large plane 423 at the high point of the rotating cam 42 and the plane 432 of the support plate 4 are tightly attached to each other under the tension of the springs on both sides to play a self-locking role, and the rotating cam 42 can no longer rotate, ensuring that the motor stops outputting clockwise torque, and the key 3 will not retract into the housing 1 when pressed. During the game, the user can press the button 3, and the pressing boss 31 of the button 3 will press against the DOME sheet 5 to deform it and send a pressing signal to the main control board 2, thereby controlling the game.

[0028] When the user finishes the game, the button 3 needs to be retracted into the housing 1, and the Figure 3 , the main control board 2 controls the motor to rotate counterclockwise. At this time, the force of the rotating cam 42 on the support plate 43 disappears, and the support plate 43 will move in the direction of retracting the key 3 under the action of the elastic restoring force of the spring, and pull the key 3 back through the end of the pull rod screw 45. When the rotating cam 42 rotates to its first limiting portion 421 and abuts against the first limiting plane 111 of the limiting boss 11 again, the motor is powered off and stops outputting torque, and the key 3 is retracted. At this time, the rotating cam 42 is at the lowest point, and there is spring tension on both sides of the key 3 on the support plate 43. The rotating cam 42 cannot push out the key 3 without the clockwise torque output by the motor, and each structure remains in the initial position.

[0029] Furthermore, a gap of 0.05-0.1 mm is provided between the DOME sheet 5 and the pressing boss 31 , thereby ensuring the user's pressing feel of the button 3 and improving the gaming experience.

[0030] Furthermore, the number of the buttons 3 is set to two, and the two buttons 3 are respectively arranged at the two ends of the longer side of the shell 1, referring to Figure 6, which further conforms to the user's regular operating habits and enhances the user's feel and gaming experience.

[0031] Further, refer to Figure 6, the DOME sheet 5 and the rotation drive device 41 are connected to the main control board 2 through the FPC cable 6. It should be noted that the existing mobile phone circuit boards are all set close to the camera position on the top of the mobile phone. Therefore, in this embodiment, the button 3 and the lifting mechanism 4 close to the side of the main control board 2 can be directly connected to the main control board 2 through the FPC cable 6, and the button 3 and the lifting mechanism 4 far away from the side of the main control board 2 can add a control board 7 connected by the FPC cable 6 next to them. The control board 7 is connected to the main control board 2 through the FPC cable 6. It should be noted that the control board 7 and the main control board 2 are both provided with FPC connectors, so as to facilitate assembly and installation, improve production efficiency, and reduce production costs.

[0032] It should be noted that in this embodiment, two mechanical buttons 3 are arranged on the longer side of the shell 1, which are very close to the positions of the buttons "left L" and "right R" in the game handle. When playing games, the screen is held horizontally with both hands, and the index fingers of the left and right hands just press them, which conforms to people's operating habits of games. Through software settings, different game function buttons 3 can be alluded to. The sensitivity and rebound effect of the mechanical buttons 3 allow gamers to play more handily. It can provide perfect elastic feel, zero delay, and zero false touch feedback. Through software settings, the physical button 3 rises when entering the game state, and the button 3 can be pressed to trigger. When exiting the game, the button 3 automatically returns to the shell 1 and is hidden and cannot be pressed, preventing false presses and damage to the appearance. The software setting can be achieved by conventional technical means in this field. This is not the main improvement point of this application, so it will not be repeated here.

[0033] Furthermore, in addition to being used for operations in the game, button 3 in this embodiment can also be set as a shutter button for horizontal shooting through software. When entering the horizontal shooting mode, button 3 automatically rises, and the mechanical shutter makes shooting faster and more convenient. Button 3 automatically falls back to exit horizontal shooting.

[0034] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
