The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Please refer to the fingerprint module anti-shake structure of fig. 1, which includes a fingerprint module 01, a touch pad 02, a rubber sleeve 03, a conductive base 04 and a supporting frame 05, wherein the touch pad 02 and the supporting frame 05 are fastened to form an accommodating cavity 06, and the fingerprint module 01, the rubber sleeve 03 and the conductive base 04 are accommodated in the accommodating cavity 06 in sequence along a first direction. In this embodiment, first direction is vertical direction, and the second direction is the horizontal direction the bottom surface of touch pad 02 is still fixed the one end of gum cover 03, the other end downwardly extending of gum cover 03 encloses and establishes fingerprint module 01's periphery, with fingerprint module 01's bottom surface is connected, holds from the below right fingerprint module 01, will fingerprint module 01 hang and support in accept in the chamber 06, seted up the intercommunication on the touch pad 02 accept the through-hole 21 of chamber 06, fingerprint module 01 partly hang in accept in the chamber 06, another part by through-hole 21 stretches out for user's finger contact is pressed. Gum cover 03 with the bottom surface of fingerprint module 01 is connected for fingerprint module 01 is central symmetry's form, can guarantee like this that the user is pressing when fingerprint module 01 the atress of gum cover 03 is balanced. The conductive base 04 is fixed on the bottom surface of the support frame 05 and is opposite to the bottom surface of the fingerprint module 01, and the distance between the fingerprint module 01 and the conductive base 04 in the vertical direction in a free state is the fingerprint key stroke of the anti-shaking structure.
The user is after pressing the fingerprint button, promotes 01 downstream of fingerprint module, at the motion in the gum cover 03 because of quilt fingerprint module 01 drags and produces elastic deformation, fingerprint module 01 is in under the elastic tension effect of gum cover 03, because the atress is balanced and the horizontal direction displacement does not take place, direct vertical downstream extremely contact takes place in electrically conductive base 04 department to the switch-on circuit is in order to carry out the fingerprint identification action.
In some embodiments, the process of directly connecting the fingerprint module 01 and the rubber sleeve 03 for assembly molding is complex, and the process requirement for directly bonding metal and rubber is high, so that the yield of the process is easily affected by directly connecting the fingerprint module 01 and the rubber sleeve 03. Therefore, a fixed gum 07 is arranged at the joint of the bottom of the fingerprint module 01 and the rubber sleeve 03 in advance, the fixed gum 07 is easy to connect with the bottom surface of the fingerprint module 01 due to shape fitting, and the fixed gum 07 is used as a transition piece and then connected with the rubber sleeve 03, so that the connection reliability and the connection quality can be improved.
The rubber sleeve 03 has a section of clamping portion 031 and a section of bearing portion 032, the clamping portion 031 is arranged between the bottom surface of the touch pad 02 and the support frame 05, and the clamping portion 031 is clamped by the clamping portion 031 to fix the rubber sleeve 03. Bearing portion 03 is the level setting, is in the bottom of fingerprint module 01, the bearing upwards holds fingerprint module 01. Clamping part 031 with be hanging part 033 between the bearing part 032, hanging part 033 is the free segment fingerprint module 01 downward fortune in-process clamping part 031 with bearing part 032 is because fixed and not take place deformation, only hanging part 033 just can take place to warp, thereby provides the elastic tension of gum cover 03.
The hanging part 033 may further include a bent segment 331, and the bent segment 331 does not generate elastic deformation at the beginning when the fingerprint module 01 descends, but starts to provide elastic tension after the fingerprint module 01 travels to straighten the bent segment 331. The curved portion 331 is configured to adjust the starting point of the elastic deformation of the hanging portion 033 during the pressing down of the fingerprint module 01.
In the same consideration, the side surface of the frame of the fingerprint module 01 not accommodated in the accommodating cavity 06 may not be provided with a vertical surface, but is provided with an inverted trapezoidal structure with a lower portion smaller than an upper portion, and the acute angle value of the inverted trapezoidal structure is α, when the fingerprint module 01 is pressed and contacted with the conductive base 04, the included angle between the hanging portion 033 of the rubber sleeve 03 and the horizontal direction is β, and at this time, the maximum deformation position of the hanging portion 033 in the whole accommodating cavity 06, that is, the maximum included angle between the hanging portion 033 and the horizontal direction, as long as α is greater than or equal to β, it can be ensured that the frame of the fingerprint module 01 does not contact the rubber sleeve 03, and the rubber sleeve 03 is prevented from being scratched.
Since the hanging part 033 is elastically deformed frequently, if the hanging part 033 has a thin cross-section, it is not preferable to maintain the life of the hanging part itself. However, the current mobile devices tend to be light and thin, the clamping portion 031 of the rubber sleeve 03 is clamped between the touch pad 01 and the supporting frame 05, and if the section of the clamping portion 03 is too thick, the overall thickness control of the mobile device is not facilitated. If the cross section of the bearing portion 032 is also thicker, the bearing portion 032 may contact with the conductive base 04 or the supporting frame 05 in advance during the descending process, which may affect the contact between the fingerprint module 01 and the conductive base 04. Therefore, the rubber sleeve 03 can be arranged in a differentiated manner according to the cross-sectional thicknesses of different positions, and specifically, the clamping portion 031 and the bearing portion 032 are thinner than the cross-section of the hanging portion 033.
When a user presses a fingerprint key, the user often does not directly press the center position of the fingerprint module 01 due to various deviations, and under the condition of eccentric pressing, if the fingerprint module 01 closest to the pressed position is not connected with the hanging part 033, the hanging part 033 nearby needs to provide elastic force to limit the shaking of the fingerprint module 01, obviously, if the hanging part 033 nearby is too far away, the limiting force which can be provided by the hanging part 033 is relatively small, and the effect which can be obtained by the shaking prevention structure is relatively weakened. In order to achieve a better anti-shaking effect, the hanging part 033 should be connected with the fingerprint module 01 around the side surface without interruption, so as to ensure that the hanging part 033 provides elastic support at any eccentric position for the operator.
Because it is the confined space to accept the chamber 06, the incessant connection of hanging 033 will accept the chamber 06 and cut apart into two parts from top to bottom the fingerprint module 01 pushes down the in-process and causes the atmospheric pressure of two parts from top to bottom uneven easily, produces certain influence to the feel of button. Therefore, the hanging part 033 is provided with the ventilation holes 332 for balancing the air pressure inside the accommodating cavity, which can help to improve the hand feeling of the key.
The invention also relates to a mobile terminal comprising the anti-shaking structure, and the mobile terminal has the characteristics of the suspended rubber sleeve 03 and the like, so that the effects of no shaking and the like of the fingerprint key when being pressed are achieved.
The anti-shaking structure of the fingerprint module of the mobile terminal comprises the fingerprint module, the touch pad, the rubber sleeve, the conductive base and the support frame, wherein the touch pad and the support frame are buckled to form an accommodating cavity, the rubber sleeve is used for suspending and supporting the fingerprint module, the rubber sleeve generates tensile force due to elastic deformation in the process that the fingerprint module is pressed down to form a passage with the conductive base, the tensioned rubber sleeve keeps the fingerprint module not to shake in the horizontal direction, meanwhile, the fingerprint module is not extruded and blocked in the vertical direction, the fingerprint module can move in the stroke range smoothly, the hand feeling is guaranteed, and meanwhile, the consistency can be well controlled.
