[0024] To facilitate the understanding of the present utility model, the present utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is expressed as "fixed to" another element, it can be directly on the other element, or there can be one or more intermediate elements therebetween. When an element is expressed as "connected to" another element, it can be directly connected to the other element, or there can be one or more intermediate elements therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are only for the purpose of illustration.
[0025] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in this specification in the description of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.
[0026] The existing button mechanism usually adopts a swing arm type. Specifically, the swing arm type button mechanism includes a button, a swing arm and a motion component connected to the swing arm. The button is directly connected to the swing arm. When the button is pressed by an external force, the button drives the swing arm to rotate. The swing arm relies on the lever action to convert the force borne by the button into the driving force for driving the unlocking mechanism to move, so as to realize the movement of the swing arm to push the motion component connected thereto. The movement of this motion component includes but is not limited to unlocking operations, switch on / off operations of buttons and electronic components, etc. Specific unlocking operations and switch on / off operations will not be exemplified one by one in this embodiment.
[0027] Assume that the above button mechanism is applied to the unlocking operation. Due to the swing arm type button mechanism, during the process of pressing the button, the movement of the swing arm is similar to a lever movement. Therefore, during the actual pressing process of the button fixed at one end of the swing arm, it will deflect and displace at a certain angle so that the motion component located at the other end of the swing arm can move along a predetermined motion trajectory. Usually, the width of the groove for accommodating the button is greater than the width of the button. When the button is pressed, the gap between the button and the side wall of the groove will decrease as the pressing depth increases, resulting in uneven gaps between the button and the side wall of the groove. And when the pressing depth reaches a certain value, there will be a collision between the button and the side wall of the groove due to no gap, resulting in jamming of the button during the pressing process.
[0028] To solve the above technical problems, this embodiment provides a button mechanism 1000. Please refer toFigure 1 and Figure 2 As shown in Figure 1 , Figure 2 , and , the key mechanism 1000 includes a base 1, a button 2, and an elastic component 3. The button 2 and the elastic component 3 are both received in the base 1. Specifically, the base 1 is provided with a pressing hole 11 and a fixing portion 12. The pressing hole 11 is formed by penetrating the plate body of the base 1 along the first direction X; the button 2 is movably arranged in the pressing hole 11, and the button 2 can reciprocate along the first direction X. The button 2 is provided with a first inclined surface 21; the elastic component 3 is movably connected to the fixing portion 12, and the elastic component 3 can reciprocate along the second direction Y. The elastic component 3 is provided with a second inclined surface 31.
[0029] Please refer to Figure 1 , Figure 5 and Figure 6 When the button 2 is pressed, the first inclined surface 21 abuts against the second inclined surface 31, and the button 2 pushes the elastic component 3 to move along the second direction Y; when the button 2 is released, the elastic component 3 moves in the reverse direction of the second direction Y, and the elastic component 3 pushes the button 2 to move in the reverse direction of the first direction X. Among them, the first direction X is perpendicular to the second direction Y. The elastic component 3 is used to provide energy storage and a steering path for the movement of the button 2. When the button 2 is pressed, the force applied to the button 2 is absorbed and stored by the elastic component 3. When the button 2 is released, the force stored by the elastic component 3 will push the button 2 back to the initial state when it is not pressed. And the second inclined surface 31 of the elastic component 3 can cooperate with the first inclined surface 21 of the button 2 to realize the change of the movement direction of the button 2. Specifically, when the button 2 is pressed, the button 2 moves along the first direction X, and the first inclined surface 21 and the second inclined surface 31 cooperate with each other to form a certain angle so that the elastic component 3 can move along the second direction Y. Thus, the movement of the button 2 in the first direction X is converted into the movement of the elastic component 3 in the second direction Y. This way of cooperation between the first inclined surface 21 and the second inclined surface 31 makes the gap between the button 2 and the pressing hole 11 remain consistent during the process of the button 2 being pressed and released. And because the first inclined surface 21 and the second inclined surface 31 are respectively arranged on the button 2 and the elastic component 3, the first inclined surface 21 and the second inclined surface 31 are in surface-to-surface contact and surface mating movement mode when they contact. Compared with the lever rotation movement mode of the existing swing-arm type key mechanism, the surface mating movement mode of the first inclined surface 21 and the second inclined surface 31 in this embodiment avoids the occurrence of jamming.
[0030] It should be noted that the first direction X and the second direction Y are not limited to being perpendicular, but can also be in an obtuse or acute angle state. When the first direction X and the second direction Y are in an obtuse or acute angle, the angle between the first inclined surface and the second inclined surface needs to be adjusted. This embodiment will not give detailed examples one by one. In this embodiment, since the first direction X and the second direction Y are perpendicular to each other, the angle between the first inclined surface 21 and the second inclined surface 31 is also 90°. Specifically, but not limited to, when the angle of the first inclined surface 21 relative to the first direction X is 30°, the angle of the second inclined surface 31 relative to the first direction X is 60°; when the angle of the first inclined surface 21 relative to the first direction X is 45°, the angle of the second inclined surface 31 relative to the first direction X is 45°, etc. In this embodiment, preferably, the angle of the first inclined surface 21 relative to the first direction X is 45°, and the angle of the second inclined surface 31 relative to the first direction X is 45°.
[0031] For the above button, please refer to Figure 1 and Figure 3 , the button 2 includes a pressing part 22 and a limiting part 23. The pressing part 22 is connected to the limiting part 23. The pressing part 22 and the limiting part 23 are integrally formed, and the shapes of the pressing part 22 and the limiting part 23 include, but are not limited to, circular, rectangular, any irregular shape, or a combination of any two of the above shapes; the pressing hole 11 includes a first through hole 111 and a second through hole 112. The first through hole 111 is communicated with the second through hole 112. The pressing part 22 is received in the first through hole 111. The first through hole 111 is used to guide the movement track of the pressing part 22 and form a limit on the pressing part 22. The limiting part 23 is received in the second through hole 112. The second through hole 112 is used to guide the movement track of the limiting part 23 and form a limit on the limiting part 23. The surface contact between the limiting part 23 and the second through hole 112 further ensures the straightness of the movement track of the button 2 during being pressed, avoiding the occurrence of tilting. And there is a clearance fit between the pressing part 22 and the first through hole 111, and a clearance fit between the limiting part 23 and the second through hole 112, so as to ensure that when the button 2 reciprocates along the first direction X, the movements of the pressing part 22 and the limiting part 23 can proceed smoothly, ensuring a good feel of the button 2 during pressing.
[0032] It can be understood that the shape of the first through hole 111 is adapted to the shape of the pressing part 22, and the shape of the second through hole 112 is adapted to the shape of the limiting part 23, so that the first through hole 111 forms an effective limit on the pressing part 22 and the second through hole 112 forms an effective limit on the limiting part 23.
[0033] In some embodiments, please refer to Figure 2, the first through hole 111 extends along the first direction X in which the button 2 moves to form a first hole wall 1111. The first hole wall 1111 ensures that the limiting effect on the pressing part 22 is continuously effective during the movement of the pressing part 22 along the first direction X. The second through hole 112 extends along the second direction Y in which the button 2 moves to form a second hole wall 1121. The second hole wall 1121 ensures that the limiting effect on the limiting part 23 is continuously effective during the movement of the limiting part 23 along the first direction X.
[0034] In some embodiments, please refer to Figure 2 and Figure 3 , at least two positioning grooves 1112 are provided on the side wall of the first through hole 111; that is, at least two positioning grooves 1112 are provided on the first hole wall 1111. The positioning grooves 1112 are obtained by grooving the first hole wall 1111 along the first direction X. At least two positioning parts 221 extend from the pressing part 22. The positioning parts 221 are obtained by extending a part of the side wall of the pressing part 22 along the second direction Y. One positioning part 221 is received in one positioning groove 1112, and the positioning part 221 reciprocates along the first direction X in the positioning groove 1112. The positioning groove 1112 is used to guide the movement of the positioning part 221 and cooperate with the first hole wall 1111 to form a limit on the positioning part 221 along the second direction Y, so as to prevent the pressing part 22 from generating a large amplitude of shaking along the second direction Y during the movement along the first direction X.
[0035] In some embodiments, please refer to Figures 3 to 6 , a guiding rib 231 is provided on the surface of the limiting part 23 close to the pressing part. The second through hole 112 is provided with a guiding groove 1122 adapted to the guiding rib 231, that is, the guiding groove 1122 is located on the second hole wall 1121. The guiding rib 231 is in line contact with the guiding groove 1122 to realize the guiding of the movement of the limiting part 23 along the second direction Y, so as to greatly reduce the friction between the limiting part 23 and the side wall of the second through hole 112, ensure the stability during the movement of the button 2, and improve the pressing feel of the button 2.
[0036] It can be understood that the surface of the above guiding rib 231 facing the first hole wall 1111 is an arc-shaped surface, and the arching radian of the arc-shaped surface is set according to actual needs, as long as it is ensured that the guiding rib 231 is in line contact with the first hole wall.
[0037] For the above elastic component 3, please refer to Figure 4, the elastic component 3 includes a moving plate 32 and an elastic member 33. The moving plate 32 is a plate-shaped body parallel to the second direction Y, and the moving plate 32 can reciprocate along the second direction Y. One end of the elastic member 33 abuts against the moving plate 32, and the other end of the elastic member 33 abuts against the base 1. The elastic member 33 is used to convert the acting force transmitted from the button 2 to the moving plate 32 into elastic potential energy when the button 2 is in the pressed state. When the button 2 is released, the elastic potential energy is released and converted into a driving force for driving the moving plate 32 to move.
[0038] It can be understood that the above-mentioned elastic member 33 has the characteristic of converting the acting force it receives into elastic potential energy. Therefore, the above-mentioned elastic member 33 includes but is not limited to: springs, elastic sheets, etc. In this embodiment, preferably, the elastic member 33 is a spring, and the number of the elastic members 33 is at least two, so that the energy storage capacity of the elastic component 3 when converting the force transmitted by the button 2 into elastic potential energy is enhanced, and at least two elastic members 33 make the moving plate 32 move more smoothly during the movement process, improving the user experience.
[0039] The ways in which the elastic component 3 is movably connected to the fixing portion 12 include but are not limited to: a sliding groove and a slider, a bearing and a rotating shaft, a slide rail and a slider, etc. Preferably, in this embodiment, the movable connection between the elastic component 3 and the fixing portion 12 is realized in the following way, specifically:
[0040] For the above-mentioned moving plate 32, please refer to Figure 1 , Figure 2 and Figure 4 , the moving plate 32 is provided with at least three third through holes 321. The three third through holes 321 are arranged around the circumference of the pressing hole 11 in a triangular distribution state. Specifically, the three third through holes 321 are arranged around the circumference of the first through hole 111. The moving plate 32 abuts against the end face of the pressing hole 11, that is, the moving plate 32 abuts against the end face of the first hole wall 1111 extending from the first through hole 111, so that the end face of the first hole wall 1111 provides support for the moving plate 32; the shape of the third through hole 321 is a runway shape, and the runway-shaped third through hole 321 restricts the movement path of the moving plate 32. The fixing portion 12 includes at least three convex columns 121. The convex columns 121 are inserted into the third through holes 321 and partially extend out of the third through holes 321. A screw hole 1211 is provided at the end of the convex column 121; the convex column 121 cooperates with the third through hole 321 to realize the restriction of the movement path of the moving plate 32; the button mechanism 1000 further includes at least three screw connectors 4. A screw connector 4 is screwed into a screw hole 1211. There is a gap between the screw connector 4 and the moving plate 32. The moving plate 32 is fixed on the convex column 121 through the screw connector 4 to prevent the moving plate 32 from shifting along the first direction X.
[0041] In some embodiments, please refer to Figure 1 and Figure 4, the moving plate 32 is further provided with a fourth through hole 322 which penetrates the plate body of the moving plate 32 along the first direction X. The second inclined surface 31 is arranged on the side wall of the fourth through hole 322. The button 2 extends along the first direction X with an abutting column 24, and the first inclined surface 21 is arranged on the abutting column 24. The abutting column 24 is used to move along the first direction X when the button 2 is pressed, so that the first inclined surface 21 can smoothly abut against the second inclined surface 31, thus facilitating the transmission of movement and the change of the movement direction. And the length of the fourth through hole 322 along the second direction Y is greater than the diameter of the abutting column 24, so that when the abutting column 24 moves along the first direction X, there is enough movement space for the first inclined surface 21 to push the second inclined surface 31 to move along the second direction Y. The above structure enables a higher integration degree between the button 2 and the elastic component 3, saving the space occupied by the key mechanism 1000.
[0042] It can be understood that the movement stroke that the button 2 can be pressed is jointly restricted by the length of the fourth through hole 322 along the second direction Y and the length of the third through hole 321 along the second direction Y. Therefore, the length of the fourth through hole 322 along the second direction Y and the length of the third through hole 321 along the second direction Y need to be determined according to the actual movement stroke required for key pressing, and no further examples will be given in this embodiment.
[0043] In order to facilitate the above-mentioned limiting part 23 not to collide with the moving plate 32 during the movement along with the pressing part 22, in some embodiments, please refer to Figure 4 , the moving plate 32 is provided with an avoidance groove 323. A part of the second hole wall 1121 passes through the avoidance groove 323 and extends out. The length of the avoidance groove 323 along the second direction Y is greater than the length of the limiting part 23 along the second direction Y, so that during the process of the limiting part 23 moving along the first direction X along with the pressing part 22, the limiting part 23 will not collide with the moving plate 32.
[0044] It can be understood that the above-mentioned avoidance groove 323 can also be a through hole similar to the fourth through hole 322, or the length of the second hole wall 1121 along the first direction X can be shortened, and there is a gap between the end surface of the second hole wall 1121 and the moving plate 32, and this gap is sufficient to ensure that during the process of the limiting part 23 moving along the first direction X, the limiting part 23 will not collide with the moving plate 32.
[0045] It should be noted that the above key mechanism 1000 can be applied to scenarios such as unlocking, switching on and off power, etc. In this embodiment, preferably, the above key mechanism 1000 is applied to the unlocking scenario. Specifically: please refer to Figure 7, the base 1 includes a first housing 13 and a second housing 14, and the first housing 13 is rotatably connected to the second housing 14; the pressing hole 11 and the fixing portion 12 are both provided on the first housing 13; the elastic component 3 is provided with a locking tongue 34, and the locking tongue 34 is provided on the moving plate 32. Specifically, the locking tongue 34 is provided at one end of the moving plate 32 away from the limiting portion 23; the second housing 14 is provided with a locking groove 141, and the locking tongue 34 is received in the locking groove 141; when the button 2 is pressed, the first inclined surface 21 abuts against the second inclined surface 31, and the button 2 pushes the elastic component 3 to move along the second direction Y, and the locking tongue 34 disengages from the locking groove 141, and the button 2 is in the unlocked state; when the button 2 is released, the elastic component 3 moves in the reverse direction of the second direction Y, and the elastic component 3 pushes the button 2 to move in the reverse direction of the first direction X, and the locking tongue 34 extends into the locking groove 141, and the button 2 is in the locked state.
[0046] To improve the smoothness of the operation during locking, please refer to Figure 4 and Figure 7 , the locking tongue 34 is provided with a third inclined surface 341, and the third inclined surface 341 is provided on the surface of the locking tongue 34 facing away from the button 2. And the locking tongue 34 provided with the third inclined surface 341 enables the first housing 13 and the second housing 14, when in the unlocked state, only by pushing the first housing 13 to rotate, the third inclined surface 341 of the locking tongue 34 abuts against the second housing 14. As the first housing 13 rotates, the portion of the second housing 14 in contact with the third inclined surface 341 pushes the third inclined surface 341 to move along the second direction Y, thereby driving the moving plate 32 to move along the second direction Y. When the first housing 13 and the second housing 14 are flush, the locking operation is completed.
[0047] The present utility model also provides an embodiment of an electronic device, including the above-mentioned key mechanism 1000. For the mechanism and functions of the key mechanism 1000, please refer to the above-mentioned embodiments, and the present embodiment will not be exemplified one by one.
