Background
Currently, mobile terminals on the market are more and more devices with fingerprint identification function on the front surface. These devices typically use a key press to drive the fingerprint module downward to turn on the conductive base to turn on the fingerprint authentication function. The whole mobile terminal is complex in assembly structure, more parts are matched with the fingerprint module, and in addition, in order to ensure the lightness and thinness of the mobile device, a mobile terminal manufacturer can provide a space for the fingerprint module to perform a pressing stroke to be further compressed, and the problem that a pressing structure with moderate stroke and stable keys needs to be solved is provided in a limited space.
The existing fingerprint module key designs on the market do not apply lateral force constraint in the process of pressing the fingerprint module because the user feeling is not noticed or the cost is reduced, and most of the existing fingerprint module key designs have serious left-right shaking problems (see fig. 2) although the hand feeling of the key can be ensured. Some manufacturers begin to recognize this problem and attempt to limit the left-right shake of the fingerprint module by using a tray-type rubber pad (see fig. 3) or a bracket for hard support (see fig. 4) to shorten the stroke, but the effect is not as ideal as expected: on one hand, the supporting form of the tray type rubber sleeve is easy to deform, and the rubber sleeve cannot be guaranteed to be overlapped with the center due to the fact that stress points and the center cannot be guaranteed in the process of being extruded by the fingerprint module, the stroke of pressing down each time cannot be guaranteed, and the consistency of pressing hand feeling is also affected; when the fingerprint module is pressed down to the support hard support, the whole fingerprint module stroke is relatively reduced, and the whole hand feeling of the key is poor although shaking can be improved.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Please refer to the anti-shake structure of the fingerprint module of fig. 1, which comprises 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 buckled to form a containing cavity 06, and the fingerprint module 01, the rubber sleeve 03 and the conductive base 04 are sequentially contained in the containing cavity 06 along a first direction. In this embodiment, the first direction is a vertical direction, the second direction is a horizontal direction, one end of the rubber sleeve 03 is further fixed on the bottom surface of the touch pad 02, the other end of the rubber sleeve 03 extends downward, is enclosed on the periphery of the fingerprint module 01, is connected with the bottom surface of the fingerprint module 01, supports the fingerprint module 01 from below, hangs and supports the fingerprint module 01 in the accommodating cavity 06, a through hole 21 communicating with the accommodating cavity 06 is formed in the touch pad 02, one part of the fingerprint module 01 is hung in the accommodating cavity 06, and the other part extends out of the through hole 21, so that a finger of a user contacts and presses. The rubber sleeve 03 is connected with the bottom surface of the fingerprint module 01 and is in a central symmetry mode relative to the fingerprint module 01, so that the stress balance of the rubber sleeve 03 can be ensured when a user presses the fingerprint module 01. 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.
After a user presses a fingerprint key, the fingerprint module 01 is pushed to move downwards, in the moving process, the rubber sleeve 03 is pulled by the fingerprint module 01 to generate elastic deformation, and the fingerprint module 01 is under the action of the elastic tension of the rubber sleeve 03, does not displace in the horizontal direction because of the stress balance, and directly moves vertically downwards to the conductive base 04 to contact, so that a circuit is connected to perform fingerprint identification action.
In some embodiments, because the process of directly connecting the fingerprint module 01 and the rubber sleeve 03 is complex, and the process requirement of directly bonding the metal and the rubber is high, the direct connection of the fingerprint module 01 and the rubber sleeve 03 easily affects the yield of the process. For this reason, the bottom of the fingerprint module 01 and the joint of the gum cover 03 are provided with the fixed gum 07 in advance, the fixed gum 07 is relatively easy to connect with the bottom of the fingerprint module 01 because of the shape fitting, and the fixed gum 07 is used as a transition piece and then connected with the gum cover 03, so that the connection reliability and connection quality can be improved.
The rubber sleeve 03 is provided with a clamping part 031 and a bearing part 032, wherein the clamping part 031 is arranged between the bottom surface of the touch pad 02 and the supporting frame 05, and the clamping part 031 is used for clamping the rubber sleeve 03. The bearing part 03 is horizontally arranged and is positioned at the bottom of the fingerprint module 01, and bears the weight and upwards holds the fingerprint module 01. The hanging part 033 is arranged between the clamping part 031 and the bearing part 032, the hanging part 033 is a free section, the clamping part 031 and the bearing part 032 are not deformed because they are fixed in the downward movement process of the fingerprint module 01, and only the hanging part 033 is deformed, thereby providing elastic tension of the rubber sleeve 03.
The hanging portion 033 may further be provided with a bending section 331, and the bending section 331 does not generate elastic deformation at first in the process of descending the fingerprint module 01, but starts to provide elastic tension after the fingerprint module 01 travels to straighten the bending section 331. Therefore, the bending section 331 can adjust the elastic deformation starting point of the hanging portion 033 during the pressing process of the fingerprint module 01.
In the process that the fingerprint module 01 is pressed down to be in contact with the conductive base 04, if the distance between the rubber sleeve 03 and the fingerprint module 01 is relatively short, and elastic deformation generated after pressing down is added, the frame of the fingerprint module 01 may generate contact friction with the rubber sleeve 03, and if the frame of the fingerprint module 01 does not perform corresponding processing, the fingerprint module 01 which is too sharp and hard can cause the rubber sleeve to be scratched or even broken for maintenance after repeated friction for a plurality of times. For this purpose, arc transition treatment is required to be performed at the edge and corner of the frame of the fingerprint module 01 accommodated in the accommodating cavity 06.
For the same consideration, the side surface of the frame of the fingerprint module 01, which is not accommodated in the accommodating cavity 06, may be not configured as a vertical plane, but may be configured as an inverted trapezoid structure, the lower portion of which is smaller than the upper portion, the acute angle value of the inverted trapezoid is α, when the fingerprint module 01 is pressed down to contact 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 entire accommodating cavity 06, that is, the position where the included angle between the hanging portion 033 and the horizontal direction is the maximum, so long as α is greater than or equal to β, it may be ensured that the frame of the fingerprint module 01 does not contact the rubber sleeve 03, and scraping of the rubber sleeve 03 is avoided.
Since the suspension portion 033 needs to be frequently elastically deformed repeatedly, if the cross section of the suspension portion 033 is too thin, the maintenance of the service life thereof is not facilitated. While current mobile devices tend to be light and thin, the clamping portion 031 of the gum cover 03 is clamped between the touch pad 01 and the supporting frame 05, which is very disadvantageous for controlling the overall thickness of the mobile device if the cross section of the clamping portion 03 is too thick. However, if the cross section of the bearing portion 032 is thicker, the bearing portion 032 may contact with the conductive base 04 or the supporting frame 05 in advance during the descending process, so as to affect the contact between the fingerprint module 01 and the conductive base 04. Therefore, the rubber sleeve 03 may have different cross-sectional thicknesses at different positions, and specifically, the clamping portion 031 and the bearing portion 032 may each have a thinner cross-section than the hanging portion 033.
When a user presses a fingerprint key, the user often does not directly press the fingerprint module 01 at the center because of various deviations, and if the hanging portion 033 is not connected to the fingerprint module 01 closest to the pressing portion in the case of eccentric pressing, the hanging portion 033 needs to provide an elastic force to limit the shaking of the fingerprint module 01, and obviously, if the distance between the hanging portion 033 is too far, the limiting force provided by the hanging portion 033 is relatively small, and the shaking preventing structure of the present invention can obtain relatively weak effects. In order to achieve a better anti-shake effect, the hanging portion 033 should be continuously connected with the side face of the fingerprint module 01 around a circle, so as to ensure that an operator has the hanging portion 033 at any eccentric position to provide elastic support.
Because the accommodating cavity 06 is a sealed space, the uninterrupted connection of the hanging portion 033 may divide the accommodating cavity 06 into an upper portion and a lower portion, which easily causes uneven air pressure in the upper portion and the lower portion in the process of pressing the fingerprint module 01, and thus, the hand feeling of the key is affected to a certain extent. Therefore, the ventilation holes 332 are formed in the hanging portion 033 to balance the air pressure inside the accommodating cavity, which can help to improve the touch feeling of the keys.
The invention also relates to a mobile terminal comprising the anti-shaking structure, and the mobile terminal has the characteristics of the hanging rubber sleeve 03 and the like, so that the effects of shaking and the like when a fingerprint key is pressed are achieved.
The invention relates to an anti-shaking structure of a fingerprint module of a mobile terminal, which comprises the fingerprint module, a touch pad, a rubber sleeve, a conductive base and a support frame, wherein the touch pad and the support frame are buckled to form a containing cavity, the rubber sleeve is hung and supports the fingerprint module, the rubber sleeve generates tension due to elastic deformation in the process of pressing down the fingerprint module and forming a passage with the conductive base, the tensioned rubber sleeve keeps the fingerprint module from shaking in the horizontal direction, meanwhile, the fingerprint module is not blocked by extrusion in the vertical direction, can move smoothly in the range of travel, the hand feeling is ensured, and meanwhile, the consistency can be well controlled. In addition, the thickness, key comfort and the like of the whole mobile equipment are further optimized by further setting the rubber sleeve, so that better user experience is obtained.
The above-described embodiments do not limit the scope of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the above embodiments should be included in the scope of the present invention.
