Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, 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 application.
Referring to fig. 1 to 6, the present application discloses a key module, which includes a frame 100, a key cap 300, a limiting bracket 500, and an elastic member 700. The frame 100 is a main body part and an installation foundation of the device, such as a middle frame of a mobile phone, specifically, the frame 100 may be provided with a groove 110, at least a part of the key cap 300 is provided in the groove 110, and the key cap 300 may slide in the groove 110, so that the key module can realize corresponding functions by controlling the sliding of the key cap 300.
In the case of sliding key cap 300, elastic member 700 drives stopper bracket 500 to maintain contact with key cap 300, so that the contact between stopper bracket 500 and key cap 300 is flexible. Particularly, along with the continuous change of the actual contact position between the limiting support 500 and the key cap 300 in the sliding process, the elastic member 700 can adjust the limiting support 500 to approach or be away from the key cap 300 through the elastic deformation of the elastic member, so that the variation range of the extrusion force between the limiting support 500 and the key cap 300 is reduced, namely, the extrusion force is determined by the elastic deformation degree of the elastic member 700, and compared with a rigid contact mode, the mode of realizing flexible contact through the elastic member 700 can reduce the abrasion of the limiting support 500 and the key cap 300 in the sliding process, and the service life of the key module is prolonged.
Further, for the specific structure of the first limiting notch 321 and the first limiting protrusion 510, the first limiting notch 321 may be provided with a first arc protrusion facing the limiting bracket 500. The first limiting protrusion 510 may be provided with a second arc protrusion facing the second sliding portion 320, and the key cap 300 may slide to a limiting position.
Under the condition that the first arc surface bulge and the second arc surface bulge are sequentially arranged towards the first direction, the first limiting notch 321 is in limiting fit with the first limiting bulge 510, and the first direction is consistent with the sliding direction of the key cap 300. In this case, the first direction may be two opposite directions, for example, the key may be slid leftward, and then the first direction may be leftward, or may be a rightward direction opposite to the leftward direction. It can be seen that, in this case, the second arc protrusion forms a stop for the first arc protrusion, so as to limit the continuous sliding of the key cap 300, so that the key cap 300 is kept fixed at the limit position, so as to implement the corresponding function output, for example, when the key cap 300 slides to the limit position, the mobile phone can be in a mute or vibration state. At this time, the key cap can be said to be in a limit position.
In the case that the first arc protrusion and the second arc protrusion are sequentially disposed in the second direction and kept in contact with each other, the first limiting notch 321 and the first limiting protrusion 510 are disengaged from each other, where the first direction intersects with the second direction, for example, the second direction is the elastic deformation direction of the elastic member 700 and is perpendicular to the first direction. In other embodiments, the second direction may form an angle with the first direction, the angle ranging from greater than 0 ° to equal to or less than 90 °. It can be seen that in this case, the elastic element 700 is elastically deformed along with the movement of the bracket 500, so that the key module releases the current function output. At this time, the key cap can be said to be in a position away from the limit position.
It can be seen that no matter the key cap 300 is at the limiting position or leaves the limiting position, the elastic element 700 can provide the power required by the contact with the key cap 300 for the limiting bracket 500, so that the elastic element 700 not only can realize the flexible contact between the limiting bracket 500 and the key cap 300, but also can realize the effective limiting cooperation between the limiting bracket 500 and the key cap 300 to output the corresponding function.
Simultaneously the setting of first cambered surface arch and second cambered surface arch can make according to button cap 300 when the limiting position is left to needs, and the first cambered surface is protruding can carry out comparatively smooth relative motion with the second cambered surface arch, and then reduces the user and slide the drive power that the button cap 300 in-process was applyed to improve and stir the operating performance who feels and promote the button module.
Further, as for the specific structure of the elastic member 700, any structure that can realize elastic deformation and provide driving force for the spacing bracket 500, such as a spring, an elastic pad, etc., may be selected and will not be described in detail herein.
Further, the first limiting notch 321 may further have a plurality of first arc surface recesses, and the first arc surface recesses and the first arc surface protrusions are alternately arranged towards the first direction.
Under the condition that the second cambered surface is protruded and contacted with the first cambered surface in a concave mode, the first limiting notch is in limiting fit with the first limiting protrusion, and at the moment, the key cap can be called to be located at a limiting position. And under the condition that the second cambered surface is in contact with the first cambered surface, the first limiting notch and the first limiting protrusion are relieved from limiting fit, and at the moment, the key cap can be called to leave the limiting position.
In this way, in the first aspect, the key cap 300 can be easily kept at the limit position by the arrangement of the first arc surface recess, so as to avoid abnormal sliding.
In the second aspect, it can be seen that, along with the sliding of key cap 300, the second arc protrusion will always keep in contact with the first arc recess or the first arc protrusion, and generate sliding friction with the first arc recess or the first arc protrusion. This kind of first cambered surface is sunken with the protruding mode that sets up in turn of first cambered surface for the surface of first spacing breach 321 is wavy surface, and wherein the sunken trough that is equivalent to wavy surface of first cambered surface, and the protruding crest that is equivalent to wavy surface of first cambered surface, like this the contact of key cap 300 and spacing support 500 is more smooth, can avoid appearing the jamming, and further reduces wearing and tearing.
In a third aspect, if the radius of curvature of the first arc-surface concavity is equal to the radius of curvature of the second arc-surface convexity, the second arc-surface convexity and the first arc-surface concavity will make surface contact when in spacing engagement; and if the curvature radius of the first cambered surface recess is larger than that of the second cambered surface recess, the second cambered surface recess and the first cambered surface recess are in line contact during limiting matching, the contact area can be increased by the two contact modes compared with point contact and the like, the pressure generated when the first limiting projection 510 and the first limiting notch 321 are squeezed can be reduced by the increase of the contact area, the abrasion is further reduced, and the service life of the key module is prolonged.
And to the material of pressing key cap 300 and spacing support 500, can select for use Polyformaldehyde (POM) to make, polyformaldehyde intensity, rigidity are high, and elasticity is good, and antifriction wearability is good, reduction wearing and tearing that can be better, and polyformaldehyde outward appearance is smooth simultaneously, can reduce the frictional force that produces in the sliding process, improves the button module stir and feels and control the performance.
It should be noted here that the first limiting protrusions 510 may also be both configured as "V" shaped protrusions, and the first limiting notches 321 may be configured as a zigzag structure in which "V" shaped protrusions and "V" shaped recesses are alternately arranged. That is, the first limiting protrusion 510 may be provided with a first plane and a second plane which are adjacent and form an included angle with each other, the first limiting notch 321 may be provided with a third plane and a fourth plane which are adjacent and form an included angle with each other, the included angles of the first plane and the fourth plane are equal, or the included angle formed by the first plane and the second plane is smaller than the included angle formed by the third plane and the fourth plane, so in the sliding process of the key cap 300, the first edge formed at the intersection of the first plane and the second plane will be in contact with the third plane, the fourth plane or other surfaces of the key cap 300 to generate sliding friction, in the sliding process, the first edge will also be in contact with the key cap 300 in a line contact manner, and the contact area can also be increased, thereby reducing wear. This kind of setting mode is protruding compared with above-mentioned first cambered surface, the protruding and sunken application force of second cambered surface in-process will increase sliding, controls the performance and reduces, but can make the spacing cooperation effect between first spacing arch 510 and the first spacing breach 321 more stable, is difficult for receiving the external interference of colliding with, and then makes key cap 300 fix in limiting position with more stable state and in order to realize function output.
Further, the frame 100 may further include a receiving groove 120, the receiving groove 120 is connected to the groove 110 and is disposed at a bottom of the groove 110, and the elastic member 700 may be disposed at the receiving groove 120. Spacing support 500 can include first spacing base 520 and first spacing arch 510, and first spacing base 520 locates the one side that first spacing arch 510 deviates from button cap 300. At least a portion of the first stopper base 520 is positioned in the receiving groove 120 and connected to the elastic member 700, and at least a portion of the first stopper protrusion 510 is positioned in the groove 110.
This arrangement allows the frame 100 to provide a space for the elastic member 700 and the spacing bracket 500, which enhances the concealment and compactness of the device of the present application; and first spacing basal portion 520 and holding tank 120 can be through modes such as direction cooperation for according to key cap 300 in the slip process, the motion route of spacing support 500 receives the restraint and can not deviate from the preset route, thereby effectively prevent according to key cap 300 and spacing support 500 unusual such as jamming. Here, the movement path of the limiting bracket 500 means that the limiting bracket 500 performs a telescopic movement in an elastic deformation direction of the elastic member 700 during the sliding of the key cap 300, thereby extending out of or retracting into the receiving groove 120.
Further, as for the depth direction of the receiving groove 120, the depth direction of the receiving groove 120 may be consistent with the depth direction of the groove 110, and at this time, the receiving groove 120 is disposed at the bottom of the groove 110; the depth direction of the receiving groove 120 may intersect with the depth direction of the groove 110, and the receiving groove 120 may be disposed on the groove side or the groove top of the groove 110. Here, the depth direction of the receiving groove 120 refers to an elastic deformation direction of the elastic member 700, the depth direction of the groove 110 may be understood to be perpendicular to the key cap 300 in the sliding direction, and the depth direction of the groove 110 coincides with a second direction described later to ensure that the elastic member 700 can drive the position restricting bracket 500 to contact the key cap 300.
It should be noted that elastic element 700 may also be disposed outside frame 100, for example, receiving groove 120 is a through groove, and elastic element 700 drives limiting bracket 500 to extend from outside frame 100 into receiving groove 120 to achieve contact with keycap 300, which is not described in detail herein.
Further, the elastic member 700, the limiting support 500 and the key cap 300 can be sequentially arranged along the elastic deformation direction of the elastic member 700, so that the elastic member 700 can better drive the limiting support 500 to contact with the key cap 300, and further the fixing of the limiting support 500 and the key cap 300 at the limiting position is ensured.
The following specific operation modes of installing the key module in the mobile phone are exemplified as follows:
for example, the current position of key cap 300 is the first position, and at this time, the corresponding function output is provided, for example, the mute state of the mobile phone. When the function output needs to be switched, the key cap 300 can be slid first, and in the sliding state of the key cap 300, the second arc protrusion can be separated from the first arc recess corresponding to the first position, the elastic member 700 can be elastically deformed, the first limiting notch 321 can be disengaged from the first limiting protrusion 510, and the key cap 300 is separated from the first position.
Next, the key cap 300 needs to be slid to a required limit position, which is referred to as a second position, the key cap 300 remains stationary after sliding to the second position, and in a stationary state of the key cap 300, the second arc protrusion can be accommodated in the first arc recess corresponding to the second position, the elastic element 700 can restore elastic deformation, the first limit protrusion 510 can be in limit fit with the first limit notch 321, and at this time, since the key cap 300 has been switched to the second position, the mobile phone is also switched to function output corresponding to the second position, for example, the mobile phone is switched from a mute state to a vibration state.
Further, the groove 110 may include a first runner 111 and a second runner 112. The accommodating groove 120 communicates with the second chute 112 through the first chute 111. Key cap 300 may include a first sliding portion 310 and a second sliding portion 320 connected to each other, where first sliding portion 310 is slidably disposed on first sliding groove 111 and second sliding portion 320 is slidably disposed on second sliding groove 112.
The first sliding chute 111 and the second sliding chute 112 may be sequentially arranged along the second direction, and a cross-sectional area of the first sliding chute 111 perpendicular to the second direction is larger than a cross-sectional area of the second sliding chute 112 perpendicular to the second direction; the second direction intersects the sliding direction of keycap 300, such as perpendicular to each other. The cross-sectional area of the first sliding portion 310 in the direction perpendicular to the second direction is greater than the cross-sectional area of the second sliding portion 320 in the direction perpendicular to the second direction.
Thus, the groove 110 forms a stepped groove structure, and the surface of the first runner 111 for communicating with the second runner 112 forms a first stepped surface; similarly, key cap 300 also forms a stepped structure, and a surface of first sliding portion 310 facing the first stepped surface forms a second stepped surface. Due to the arrangement of the step structure, the groove 110 and the key cap 300 are matched with each other, the first step surface and the second step surface are attached to each other to form a stopping effect, and the key cap 300 is prevented from being separated from the groove 110 in the using process.
Further, the accommodating groove 120, the first sliding groove 111, and the second sliding groove 112 may be sequentially disposed along the second direction. On this basis, the second direction may be understood as an elastic deformation direction of the elastic member 700. This facilitates the transmission of the driving force applied by elastic member 700 to ensure a more effective contact between spacing bracket 500 and keycap 300.
Further, the first sliding part 310 and the second sliding part 320 may be connected in an integrated manner, and the present application adopts a combined structure, specifically, the first sliding part 310 may be provided with a first mounting hole 311 therethrough, the second sliding part 320 may include a limiting part 323 and a base part 324, the limiting part 323 is connected with the base part 324, and the first limiting notch 321 is provided on a side of the limiting part 323 away from the base part 324. The limiting portion 323 is disposed in the first mounting hole 311, and the first sliding portion 310 is detachably connected to the second sliding portion 320.
Such a structure facilitates the key cap 300 to be assembled into the frame 100, for example, the second end surface 140 may be disposed on the frame 100, wherein the second end surface 140 is located on a side of the second sliding slot 112 away from the first sliding slot 111, the second sliding slot 112 has a second notch, and the second notch is located on the second end surface 140. And a first end face 130 is disposed on the frame 100, the second end face 140 forms an included angle with the first end face 130, and the first sliding slot 111 has a first notch, and the first notch is located at the first end face 130.
In this way, during the specific assembly, the first sliding portion 310 may be first installed in the first sliding groove 111 from the first notch, then the second sliding portion 320 may be installed in the second sliding groove 112 from the second notch, and then the limiting portion 323 is inserted into the first installation hole 311, so that the first sliding portion 310 and the second sliding portion 320 are connected in the groove 110. Similarly, the first sliding portion 310 and the second sliding portion 320 can be separated from the groove 110 by removing the first mounting hole 311 from the limiting portion 323, and will not be described in detail herein.
Further, a side of the base 324 facing away from the limiting portion 323 may extend out of the second sliding slot 112 through the second notch. This is convenient for the user to operate the portion of the base 324 protruding out of the second notch, so as to shift the portion to realize the sliding of the key cap 300 in the groove 110, thereby enhancing the operation performance of the device of the present application.
In other alternative embodiments, the first limiting notch 321 may also be disposed on the first sliding portion 310, for example, the first mounting hole 311 is a blind hole, the first limiting notch 321 is disposed on a side of the first sliding portion 310 facing the limiting bracket 500, and the first mounting hole 311 is disposed on a side of the first sliding portion 310 facing away from the first limiting notch 321. However, in this arrangement, compared to the above-described arrangement in which the first mounting hole 311 is formed as a through hole and the first stopper notch 321 is formed in the second sliding portion 320, the difficulty in processing and assembling is increased, and the manufacturing cost is increased.
Further, keycap 300 may also include a connecting pin 330. The first sliding portion 310 may be provided with a first connection hole 312, the second sliding portion 320 may be provided with a second connection hole 322, the first connection hole 312 and the second connection hole 322 correspond to each other one by one, the first connection hole 312 and the second connection hole 322 are sequentially communicated toward a third direction, and the third direction intersects with the second direction, such as perpendicular to each other. At least some of the connection pins 330 are provided in the first connection holes 312 and the second connection holes 322, and the first slider 310 is connected to the second slider 320 by the connection pins 330.
It can be seen that the connection between the second sliding portion 320 and the first sliding portion 310 is more stable by the arrangement of the connection pin 330.
