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 clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the 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 of the device and an installation base, such as a middle frame of a mobile phone, and the like, specifically, the frame 100 may be provided with a groove 110, at least part of the key cap 300 is arranged 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.
The limiting support 500 is elastically connected with the frame 100 through the elastic piece 700, a first limiting protrusion 510 is arranged on one side of the limiting support 500, which is away from the elastic piece 700, and a first limiting notch 321 is arranged on one side of the key cap 300, which is towards the first limiting protrusion 510. The first limiting protrusion 510 is in limiting fit with the first limiting notch 321, so that the sliding stroke of the key cap 300 is better constrained, for example, the first limiting notch 321 is set as a chute, and then the length of the chute is the sliding stroke of the key cap 300, so as to avoid excessive sliding of the key cap 300, and it can be understood that the length direction of the chute is consistent with the sliding direction of the key cap 300.
In the case that the key cap 300 is slid, the elastic member 700 drives the spacing bracket 500 to maintain contact with the key cap 300, so that the contact between the spacing bracket 500 and the key cap 300 has flexibility. Specifically, 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 piece 700 can adjust the limiting support 500 to approach or be far away from the key cap 300 through the elastic deformation of the elastic piece, so that the change amplitude 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 piece 700, compared with the rigid contact mode, the abrasion suffered by the limiting support 500 and the key cap 300 in the sliding process can be reduced through the mode of setting the elastic piece 700, 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 cambered protrusion, and the first cambered protrusion faces the limiting bracket 500. The first limiting protrusion 510 may be provided with a second arc protrusion, the second arc protrusion faces the second sliding portion 320, and the key cap 300 may slide to the limiting position.
In the case that the first cambered surface protrusion and the second cambered surface protrusion are sequentially arranged in the first direction, the first limiting notch 321 is in limiting fit with the first limiting protrusion 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 slide to the left, and then the first direction may be the left direction or the right direction opposite to the left direction. It can be seen that, in this case, the second cambered surface protrusion forms a stop for the first cambered surface protrusion, so as to further limit the continued sliding of the key cap 300, so that the key cap 300 is kept fixed at the limiting position, and thus the corresponding function output is realized, and when the key cap 300 slides to the limiting position, for example, the key module of the mobile phone, the mobile phone can be in a mute or vibration state. At this time, the key cap may be said to be in a limit position.
And under the condition that the first cambered surface protrusion and the second cambered surface protrusion are sequentially arranged towards the second direction and keep in contact, the first limiting notch 321 is in limiting fit with the first limiting protrusion 510, and the first direction is intersected with the second direction, for example, the second direction is the elastic deformation direction of the elastic piece 700 and is mutually 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 less than or equal to 90 °. It can be seen that the elastic member 700 is elastically deformed along with the movement of the bracket 500 in this case, so that the key module releases the current function output. At this time, the key cap may be said to be in a position away from the limit.
It can be seen that, no matter the key cap 300 is at the limit position or leaves the limit position, the elastic member 700 can provide the power required for the limit bracket 500 to contact with the key cap 300, so that the elastic member 700 not only can realize flexible contact between the limit bracket 500 and the key cap 300, but also can realize effective limit fit between the limit bracket 500 and the key cap 300 for corresponding function output.
Meanwhile, due to the arrangement of the first cambered surface bulge and the second cambered surface bulge, when the key cap 300 needs to leave the limiting position, the first cambered surface bulge and the second cambered surface bulge can perform smoother relative movement, so that the driving force applied by a user in the process of sliding the key cap 300 is reduced, the toggle hand feeling is improved, and the operation performance of the key module is improved.
Further, as for the specific structure of the elastic member 700, any structure capable of realizing elastic deformation, such as a spring, an elastic pad, etc., and providing driving force to the limiting bracket 500 may be selected, and will not be described in detail herein.
Further, the first limiting notch 321 may further be provided with a plurality of first cambered surface recesses, where the first cambered surface recesses and the first cambered surface protrusions are alternately arranged towards the first direction.
Under the condition that the second cambered surface protrusion is in concave contact with the first cambered surface, the first limiting notch is in limiting fit with the first limiting protrusion, and at the moment, the key cap can be called as being in a limiting position. And under the condition that the second cambered surface bulge is contacted with the first cambered surface bulge, the first limiting notch is in limiting fit with the first limiting bulge, and at the moment, the key cap is separated from the limiting position.
Thus, in the first aspect, by the arrangement of the first cambered surface recess, the key cap 300 can be relatively easily kept at the limiting position, so as to avoid abnormal sliding.
In the second aspect, it can be seen that the second cambered surface protrusion will always maintain contact with the first cambered surface recess or the first cambered surface protrusion along with the sliding of the key cap 300, and sliding friction is generated between the second cambered surface protrusion and the first cambered surface recess or the first cambered surface protrusion. The first cambered surface is sunken and the protruding mode that sets up in turn of first cambered surface for the surface of first spacing breach 321 is the wave surface, and wherein first cambered surface is sunken to be equivalent to the trough on wave surface, and first cambered surface is protruding to be equivalent to the crest on wave surface, and the contact of button cap 300 and spacing support 500 is more smooth like this, can avoid appearing the jamming, and further reduces wearing and tearing.
In the third aspect, if the radius of curvature of the first cambered surface concave is equal to the radius of curvature of the second cambered surface convex, the second cambered surface convex and the first cambered surface concave are in surface contact during limit fit; and if the curvature radius of the first cambered surface concave is larger than that of the second cambered surface convex, the second cambered surface convex and the first cambered surface concave are in line contact during limit fit, the contact area of the two contact modes can be increased compared with the point contact mode and the like, the pressure intensity generated during extrusion between the first limit convex 510 and the first limit notch 321 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 button cap 300 and spacing support 500, can select to use Polyoxymethylene (POM) to make, polyoxymethylene intensity, rigidity are high, and elasticity is good, antifriction wearability is good, and the reduction wearing and tearing that can be better simultaneously, the polyoxymethylene outward appearance is smooth, can reduce the frictional force that produces in the slip process, improves the stirring feel and the control performance of button module.
Here, the first limiting protrusions 510 may be all V-shaped protrusions, and the first limiting notches 321 may be configured as a zigzag structure in which the V-shaped protrusions and the V-shaped recesses are alternately arranged. That is, the first limiting protrusion 510 may be provided with a first plane and a second plane that 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 that are adjacent and form an included angle with each other, and the included angle between the first plane and the fourth plane is equal, or the included angle between the first plane and the second plane is smaller than the included angle between the third plane and the fourth plane, so that 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 generate sliding friction with the third plane, the fourth plane or other surfaces of the key cap 300, and in the sliding process, the first edge will also keep contact with the key cap 300 in a line contact manner, and can also improve the contact area, thereby reducing the abrasion. Compared with the arrangement of the first cambered surface bulge, the second cambered surface bulge and the second cambered surface recess, the arrangement mode can increase the force applied in the sliding process, the control performance is reduced, but the limit matching effect between the first limit bulge 510 and the first limit notch 321 is more stable, the key cap 300 is not easy to be interfered by external collision, and the key cap 300 is fixed at a limit position in a more stable state to realize functional output.
Further, the frame 100 may further be provided with a receiving groove 120, the receiving groove 120 is communicated with the groove 110, and is disposed at a bottom of the groove 110, and the elastic member 700 may be disposed in the receiving groove 120. The spacing bracket 500 may include a first spacing base 520 and a first spacing protrusion 510, where the first spacing base 520 is disposed on a side of the first spacing protrusion 510 facing away from the key cap 300. At least a portion of the first limiting base 520 is located in the accommodating groove 120 and is connected with the elastic member 700, and at least a portion of the first limiting protrusion 510 is located in the groove 110.
The arrangement ensures that the frame 100 provides a containing space for the elastic piece 700 and the limit bracket 500, thereby enhancing the concealment and compactness of the device; the first limiting base 520 and the accommodating groove 120 may be guided to cooperate with each other, so that the movement path of the limiting bracket 500 is constrained from deviating from the preset path during the sliding process of the key cap 300, thereby effectively preventing the key cap 300 and the limiting bracket 500 from being jammed. The movement path of the limiting bracket 500 herein means that the limiting bracket 500 performs a telescopic movement along the elastic deformation direction of the elastic member 700 during the sliding process of the key cap 300, so as to extend or retract from the receiving groove 120.
Further, as for the depth direction of the accommodating groove 120, the depth direction of the accommodating groove 120 may be identical to the depth direction of the groove 110, in which case the accommodating groove 120 is disposed at the bottom of the groove 110; the depth direction of the receiving groove 120 may also intersect with the depth direction of the groove 110, and the receiving groove 120 may be disposed at the groove side or the groove top of the groove 110. The depth direction of the receiving groove 120 herein refers to the elastic deformation direction of the elastic member 700, and the depth direction of the groove 110 may be understood as being perpendicular to the sliding direction of the key cap 300, and the depth direction of the groove 110 corresponds to a second direction described later, so as to ensure that the elastic member 700 can drive the limit bracket 500 to contact with the key cap 300.
It should be noted that, the elastic member 700 may also be disposed outside the frame 100, for example, the receiving groove 120 is a through groove, and the elastic member 700 drives the limit bracket 500 to extend out of the frame 100 into the receiving groove 120 to make contact with the key cap 300, which will not be described in detail herein.
Further, the elastic member 700, the limiting bracket 500 and the key cap 300 may be sequentially arranged along the elastic deformation direction of the elastic member 700, so that the elastic member 700 can better drive the limiting bracket 500 to contact with the key cap 300, thereby ensuring the fixing of the limiting bracket 500 and the key cap 300 at the limiting position.
The following specific operation modes of installing the key module in the mobile phone are exemplified:
For example, the current limit position of the key cap 300 is the first position, and has a corresponding function output, such as a 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 cambered surface protrusion can be separated from the first cambered surface recess corresponding to the first position, the elastic piece 700 can be elastically deformed, and the first limiting notch 321 can be in limiting fit with the first limiting protrusion 510, so that the key cap 300 is separated from the first position.
Next, the key cap 300 needs to be slid to a desired limit position, herein referred to as a second position, after the key cap 300 is slid to the second position, the key cap 300 will remain stationary, and in the stationary state of the key cap 300, the second cambered protrusion can be accommodated in the first cambered recess corresponding to the second position, the elastic member 700 can recover elastic deformation, and the first limit protrusion 510 can be in limit fit with the first limit notch 321, at this time, since the key cap 300 has been switched to the second position, the mobile phone is also switched to the functional output corresponding to the second position, such as the mobile phone is switched from the mute state to the vibration state.
Further, the groove 110 may include a first chute 111 and a second chute 112. The receiving groove 120 communicates with the second sliding groove 112 through the first sliding groove 111. The key cap 300 may include a first sliding portion 310 and a second sliding portion 320 connected to each other, the first sliding portion 310 being slidably disposed in the first sliding slot 111, and the second sliding portion 320 being slidably disposed in the second sliding slot 112.
The first chute 111 and the second chute 112 may be sequentially arranged along the second direction, and the cross-sectional area of the first chute 111 perpendicular to the second direction is larger than the cross-sectional area of the second chute 112 perpendicular to the second direction; the second direction intersects, e.g., is perpendicular to, the sliding direction of the key cap 300. The cross-sectional area of the first sliding portion 310 perpendicular to the second direction is larger than the cross-sectional area of the second sliding portion 320 perpendicular to the second direction.
Thus, the groove 110 forms a stepped groove structure, and the surface of the first slide groove 111 for communicating with the second slide groove 112 forms a first stepped surface; similarly, the key cap 300 also forms a stepped structure, and a surface of the first sliding part 310 facing the first stepped surface forms a second stepped surface. The arrangement of the step structure enables the groove 110 and the key cap 300 to be mutually matched, and the first step surface and the second step surface are mutually attached to form a stopping effect, so that the key cap 300 is prevented from being separated from the groove 110 in the use 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 the direction of elastic deformation of the elastic member 700. This facilitates the transmission of the driving force applied by the elastic member 700 to ensure more effective contact between the stopper bracket 500 and the key cap 300.
Further, the first sliding portion 310 and the second sliding portion 320 may be connected in an integrally formed manner, and the present application adopts a combined structure, specifically, the first sliding portion 310 may be provided with a first mounting hole 311 therethrough, the second sliding portion 320 may include a limiting portion 323 and a base portion 324, the limiting portion 323 is connected with the base portion 324, and the first limiting notch 321 is disposed on a side of the limiting portion 323 facing away from the base portion 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.
This configuration facilitates assembly of the key cap 300 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 groove 112 facing away from the first sliding groove 111, and the second sliding groove 112 has a second notch, and the second notch is located on the second end surface 140. And a first end surface 130 is arranged on the frame 100, the second end surface 140 and the first end surface 130 form an included angle, the first chute 111 is provided with a first notch, and the first notch is positioned on the first end surface 130.
In this particular assembly, the first sliding portion 310 may be first installed into the first sliding groove 111 through the first slot, then the second sliding portion 320 may be installed into the second sliding groove 112 through the second slot, and then the limiting portion 323 may be inserted into the first mounting hole 311, so that the connection between the first sliding portion 310 and the second sliding portion 320 may be achieved 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, which 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 chute 112 through the second slot. This facilitates the user to operate the portion of the base 324 protruding out of the second slot, so as to toggle 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 surface of the first sliding portion 310 facing the limiting support 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, the processing difficulty and the assembly difficulty are increased compared to the above-mentioned arrangement in which the first mounting hole 311 is formed as a through hole and the first limiting notch 321 is formed in the second sliding portion 320, thereby increasing the manufacturing cost.
Further, the key cap 300 may further include a connection 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 are in one-to-one correspondence, 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 being perpendicular to each other. At least a portion of the connection pin 330 is provided at the first connection hole 312 and the second connection hole 322, and the first sliding portion 310 is connected to the second sliding portion 320 through the connection pin 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. Of course, the second sliding portion 320 and the first sliding portion 310 may be further firmly connected by providing a connecting structure adapted to each other between the first mounting hole 311 and the limiting portion 323, or by adopting an interference fit, etc., which will not be described in detail herein.
Further, the connection pin 330 may include a pin body 331 and a blocking lever 332, the blocking lever 332 being connected to the pin body 331, the pin body 331 being provided in plurality in the second direction. The first sliding portion 310 includes a first sliding base 313 and a first stopper 314, and a limiting groove is formed between the first sliding base 313 and the first stopper 314. The first connecting holes 312, the second connecting holes 322 and the pin bodies 331 are in one-to-one correspondence, the pin bodies 331 are arranged in the first connecting holes 312 and the second connecting holes 322, the stop rods 332 are arranged in the limiting grooves, and the first stop piece 314 is in stop fit with the stop rods 332 towards the third direction.
In this design, on one hand, the constraining effect on the first sliding portion 310 and the second sliding portion 320 is enhanced by providing a plurality of pin bodies 331, so as to improve the connection firmness between the first sliding portion 310 and the second sliding portion 320; on the other hand, the restraint of the connection pin 330 is achieved through the limit fit between the stop lever 332 and the first stopper 314, so that the connection firmness between the first sliding portion 310 and the second sliding portion 320 is enhanced. It can be seen that the key cap 300 forms a unitary structure that is not easily separated after assembly by the above design.
Further, the second chute 112 may include a first sub-chute 113 and a second sub-chute 114, and the second sub-chute 114 communicates with the first chute 111 through the first sub-chute 113. The base 324 may include a connection portion 325 and a sliding portion 326, the sliding portion 326 is connected to the limiting portion 323 through the connection portion 325, the connection portion 325 is slidably disposed in the first sub-slot 113, and the sliding portion 326 is slidably disposed in the second sub-slot 114.
The first sub-groove 113 and the second sub-groove 114 are sequentially arranged along the second direction, and the cross-sectional area of the first sub-groove 113 perpendicular to the second direction is smaller than the cross-sectional area of the second sub-groove 114 perpendicular to the second direction. The connection portion 325 and the sliding portion 326 are sequentially disposed along the second direction, and a cross-sectional area of the connection portion 325 perpendicular to the second direction is smaller than a cross-sectional area of the sliding portion 326 perpendicular to the second direction.
In this way, the second slide groove 112 forms a stepped structure, and a third stepped surface is formed on the end surface for communicating with the first sub groove 113 in the second sub groove 114. And the base 324 also forms a stepped structure, and a side of the slide cover 326 facing the third stepped surface forms a fourth stepped surface. When the user toggles the key cap 300 to slide, the third step surface and the fourth step surface are mutually adhered to form a stop effect, so that a supporting effect on the sliding cover part 326 is formed, the pressing force generated by toggling the key cap 300 is born, the toggling hand feeling of the user to the key cap 300 is further improved, and the control performance of the key module is improved.
Further, the key module may further include a first detection terminal 200 and a second detection terminal 400. The second detection terminal 400 is provided to the key cap 300, the first detection terminal 200 is provided to the frame 100, and the second detection terminal 400 and the first detection terminal 200 are electrically connected.
In this way, in the sliding state of the key cap 300, that is, when the key cap 300 needs to shift gears, the second detection terminal 400 can move along with the key cap 300, and the control performance of the key module can be further enhanced by this arrangement.
Taking the example that the key module is mounted on the mobile phone, the second detection terminal 400 may be a magnetic member, and the first detection terminal 200 may be a hall device. Thus, when the key cap 300 is in the sliding state, the distance between the second detection terminal 400 and the first detection terminal 200 will change, so that the magnetic induction intensity detected by the first detection terminal 200 changes, the first detection terminal 200 monitors the magnetic change information and feeds back the magnetic change information to the control unit on the mobile phone, and the control unit immediately responds, specifically, controls the mobile phone to perform related operations according to the current distance value between the second detection terminal 400 and the first detection terminal 200, so as to realize the function output corresponding to the key module.
