DETAILED DESCRIPTION
[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
[0029] like Figures 1 to 6As shown, the key structure 100 includes a keycap 10, a shell 20, a touch switch 30 and a waterproof member 40. The shell 20 has an installation cavity 21 inside. The keycap 10, the waterproof member 40 and the touch switch 30 are arranged in the installation cavity 21 along a first direction X, and the waterproof member 40 abuts against the keycap 10; the shell 20 is also provided with a mounting hole 22 extending along the first direction X, the mounting hole 22 is connected to the mounting cavity 21, at least part of the keycap 10 is embedded in the mounting hole 22, and the keycap 10 can move relative to the mounting hole 22 along the first direction X, so that the keycap 10 drives part of the waterproof member 40 to abut or separate from the touch switch 30, at least part of the waterproof member 40 facing the side of the keycap 10 abuts against the shell 20, and the waterproof member (40) covers the mounting hole 22.
[0030] In the embodiment of the utility model, the key structure 100 includes a keycap 10, a housing 20, a touch switch 30 and a waterproof member 40, wherein the housing 20 has an installation cavity 21 inside, and the keycap 10, the waterproof member 40 and the touch switch 30 can all be arranged in the installation cavity 21 and distributed along the first direction X. The housing 20 is also provided with an installation hole 22 extending along the first direction X. Since the installation hole 22 is connected to the installation cavity 21, a part of the keycap 10 can be embedded in the installation hole 22, so that the keycap 10 can extend from the installation cavity 21, so that the user can operate the keycap 10. Since the keycap 10 can move along the first direction X relative to the mounting hole 22, and the waterproof component 40 abuts against the keycap 10, the keycap 10 can be operated to move in the mounting hole 22 to move along the first direction X, so that the keycap 10 can drive part of the waterproof component 40 to move toward the direction close to the touch switch 30, or drive part of the waterproof component 40 to move away from the touch switch 30, so that the waterproof component 40 can abut against or separate from the touch switch 30, that is, the keycap 10 can operate the touch switch 30 through the waterproof component 40, so that the touch switch 30 can switch the on and off states, thereby realizing the function of the key structure 100. At least a portion of the waterproof member 40 facing the keycap 10 abuts against the housing 20. Since the waterproof member 40 covers the mounting hole 22, the waterproof member 40 can block the mounting hole 22 and block the moisture passing through the mounting hole 22, thereby preventing the moisture from outside from passing through the keycap 10 and the waterproof member 40 to reach the touch switch 30, causing the touch switch 30 to work abnormally, and preventing the key structure 100 from malfunctioning. When the key structure 100 is used in an electrical device, it can also prevent moisture from entering the electrical device through the mounting hole 22 and affecting the function of the electronic device.
[0031] It should be noted that the waterproof component 40 can be elastic, so that when the user operates the keycap 10 to move, the keycap 10 can drive the part of the waterproof component 40 connected thereto to move, so that the part of the waterproof component 40 abuts against or separates from the touch switch 30, and the part of the waterproof component 40 connected to the shell 20 can maintain an abutting relationship with the shell 20, which can prevent the waterproof component 40 from moving as a whole, resulting in the problem of failure of the waterproof component 40 to seal the mounting hole 22; or, the waterproof component 40 can also be non-elastic. At this time, a clamping portion can be provided on the surface of the waterproof component 40 facing the keycap 10, and the clamping portion can extend along the circumferential direction of the waterproof component 40. Correspondingly, a clamping groove can be provided on the shell 20, and the clamping portion can be embedded in the clamping groove, and the length of the clamping portion in the first direction X is greater than the stroke of the keycap 10. In this setting, even if the keycap 10 is pressed to move the waterproof component 40, the clamping portion can remain in the embedded state in the clamping groove, and can also have a sealing effect on the mounting hole 22. Of course, in the case where the waterproof member 40 is elastic, the above-mentioned clamping portion can also be provided on the waterproof member 40, and a clamping groove can be provided on the housing 20 to facilitate the connection between the waterproof member 40 and the housing 20. Among them, in the case where the waterproof member 40 is elastic, the waterproof member 40 can be made of elastic and hydrophobic materials such as rubber and silicone. The specific material of the waterproof member 40 is not specifically limited in the embodiment of the utility model.
[0032] Wherein, when the waterproof member 40 is elastic, the waterproof member 40 may also be deformed when the keycap 10 moves and drives the waterproof member 40 to move. For example, when the user presses the keycap 10 along the first direction X, the waterproof member 40 may also be compressed and move in the direction close to the touch switch 30 along the first direction X. After the user cancels the pressing of the keycap 10, the waterproof member 40 may restore the deformation. At this time, the waterproof member 40 may push the keycap 10 in the opposite direction of the first direction X, so that the keycap 10 may move in the direction away from the touch switch 30. That is, when the waterproof member 40 is elastic, the waterproof member 40 may also facilitate the resetting of the keycap 10, avoiding the use of an additional resetting structure.
[0033] It should also be noted that if Figure 1 As shown, the housing 20 may include an upper shell 25 and a lower shell 26, and a receiving cavity with an opening may be provided inside the upper shell 25 and inside the lower shell 26, and the upper shell 25 and the lower shell 26 are enclosed so that the two receiving cavities can form a closed chamber, that is, the installation cavity 21, and other components, such as batteries, etc., may also be provided in the installation cavity 21. Among them, the first direction X may be the direction from the upper shell 25 to the lower shell 26, and the installation hole 22 may be provided on the upper shell 25.
[0034] In addition, at least part of the keycap 10 is embedded in the mounting hole 22. Specifically, the keycap 10 can be arranged in different forms. For example, the entire keycap 10 can be located in the mounting hole 22. At this time, the upper and lower ends of the keycap 10 are flush with the upper and lower ends of the shell 20, respectively, so that the surface of the key structure 100 is relatively flat, and the user can press the keycap 10 located in the mounting hole 22 to operate; or, the keycap 10 can be partially extended from the mounting hole 22, and the keycap 10 is exposed to the shell 20, which is convenient for the user to press the keycap 10; or, the upper and lower ends of the keycap 10 are both extended out of the mounting hole 22. The specific arrangement of the keycap 10 is not specifically limited in the embodiment of the utility model. Among them, the upper and lower ends of the keycap 10 are the opposite ends of the keycap 10 in the first direction X, and the upper and lower ends of the shell 20 are the opposite ends of the shell 20 in the first direction X. The upper end can be the side away from the mounting cavity 21.
[0035] In addition, in some embodiments, Figure 1 , Figure 2 , Figure 3 As shown, the button structure 100 may also include a circuit board 50 and a lamp bead 51, the touch switch 30 is electrically connected to the circuit board 50, the lamp bead 51 is electrically connected to the circuit board 50, a light hole 23 is provided on the shell 20, the light hole 23 is connected to the installation cavity 21, and the light hole 23 is opposite to the lamp bead 51.
[0036] The key structure 100 also includes a circuit board 50. Since the touch switch 30 is electrically connected to the circuit board 50, the touch switch 30 can be used to turn on and off the circuit on the circuit board 50, thereby realizing the function set by the key structure 100. A lamp bead 51 is also provided on the circuit board 50, and the lamp bead 51 is also electrically connected to the circuit board 50. When the user operates the touch switch 30 through the key cap 10, the lamp bead 51 can emit light. Since a light hole 23 is provided on the housing 20, the light hole 23 is connected to the mounting cavity 21, and the light hole 23 is opposite to the lamp bead 51, therefore, when the lamp bead 51 emits light, the light can be transmitted outward through the light hole 23 to serve as a prompt to the user.
[0037] It should be noted that the lamp bead 51 can have different functions. For example, the lamp bead 51 can be set on the circuit where the touch switch 30 is located. When the user operates the touch switch 30, the circuit where the lamp bead 51 is located can be turned on or off to make the lamp bead 51 light up or go out, so that the user can determine the state of the touch switch 30; or the lamp bead 51 can also be connected to other components, such as a battery. When the user operates the touch switch 30, the circuit where the lamp bead 51 and the battery are located can be turned on to make the lamp bead 51 light up, so that the user can determine the state of the battery. The specific connection method and function of the lamp bead 51 can be set according to the actual use situation, and the embodiment of the utility model is not specifically limited here.
[0038] In addition, in some embodiments, the waterproof member 40 may be a light-transmitting member, and the waterproof member 40 covers the light-through hole 23 .
[0039] The waterproof member 40 is a light-transmitting member. Since the waterproof member 40 covers the light-through hole 23, when the lamp bead 51 emits light, the light can pass through the waterproof member 40 and enter the light-through hole 23 to be emitted outward after being transmitted to the position of the waterproof member 40. In addition, the setting of the waterproof member 40 can also block the light-through hole 23, which can prevent external moisture from entering the housing 20 through the light-through hole 23 and causing damage to the touch switch 30, circuit board 50 and other components in the housing 20. That is, in this embodiment, the waterproof member 40 can also block the position for emitting light in the key structure 100 to achieve a waterproof effect there, and the waterproof member 40 can also be light-transmitting, which can also prevent the problem that the setting of the waterproof member 40 affects the transmission of light outward.
[0040] It should be noted that the waterproof component 40 is a light-transmitting component, which means that the waterproof component 40 is made of a light-transmitting material, such as polyvinyl chloride, polyurethane, polyolefin, polyamide, etc. The specific material of the waterproof component 40 is not specifically limited in the embodiment of the utility model.
[0041] In addition, in some embodiments, Figure 2 , Figure 6 As shown, the button structure 100 may further include a mounting frame 60, on which an assembly hole 61 is provided. The assembly hole 61 penetrates the mounting frame 60 along the first direction X. The mounting frame 60 is disposed between the waterproof component 40 and the circuit board 50, and the assembly hole 61 is opposite to the touch switch 30. Part of the waterproof component 40 is passed through the assembly hole 61, and part of the waterproof component 40 passed through the assembly hole 61 can abut against or separate from the touch switch 30.
[0042] The key structure 100 further includes a mounting frame 60, which is disposed between the waterproof member 40 and the circuit board 50, and can carry the waterproof member 40 to realize the installation of the waterproof member 40. Specifically, the mounting frame 60 can be provided with an assembly hole 61, which penetrates the mounting frame 60 along the first direction X and is opposite to the touch switch 30, and part of the waterproof member 40 can be inserted into the assembly hole 61, and another part of the waterproof member 40 can be located at a position on the mounting member 41 where the assembly hole 61 is not provided, so that the mounting frame 60 can play a bearing role for the waterproof member 40, and part of the waterproof member 40 inserted into the assembly hole 61 can move under the action of the key cap 10, so that the part of the waterproof member 40 can abut or separate from the touch switch 30, so as to realize the function of the key structure 100.
[0043] In addition, in some embodiments, Figure 3As shown, a first connecting hole 67 may be provided on the mounting frame 60, and the first connecting hole 67 passes through the mounting frame 60 along the first direction X. A connecting column 211 is provided on the inner wall of the mounting cavity 21, and a second connecting hole 212 is provided on the connecting column 211. The second connecting hole 212 is opposite to the first connecting hole 67, and a connecting member 70 is provided in the first connecting hole 67 and the second connecting hole 212.
[0044] A first connecting hole 67 is provided on the mounting frame 60, and the first connecting hole 67 passes through the mounting frame 60 along the first direction X. A connecting column 211 is provided on the inner wall of the mounting cavity 21, and a second connecting hole 212 is provided on the connecting column 211. Since the second connecting hole 212 is opposite to the first connecting hole 67, a connecting member 70 can be provided in the first connecting hole 67 and the second connecting hole 212. The connecting member 70 can be connected to both the first connecting hole 67 and the second connecting hole 212, so that the mounting frame 60 can be fixed by the connecting member 70, and the mounting member 41 carries the waterproof member 40, and can also play a better fixing role for the waterproof member 40.
[0045] It should be noted that the connecting member 70 may be a threaded member, such as a screw, a bolt, a stud, etc., or the connecting member 70 may also be a pin, etc. The specific form of the connecting member 70 is not specifically limited in the embodiment of the utility model.
[0046] It should also be noted that when the waterproof component 40 is elastic, the mounting frame 60 and the shell 20 can be tightly connected during installation, so that the waterproof component 40 between the mounting frame 60 and the shell 20 has an interference fit with the shell 20 and the mounting frame 60, which can improve the sealing effect of the waterproof component 40 on the mounting hole 22 and the light hole 23.
[0047] In addition, in some embodiments, Figure 3 , Figure 4 As shown, a light guide column 611 can also be provided on the mounting frame 60, and the light guide column 611 includes a first guide column 62 and a second guide column 63. The first guide column 62 is located on the side of the mounting frame 60 facing the waterproof component 40, and the second guide column 63 is located on the side of the mounting frame 60 facing the circuit board 50, and the first guide column 62 is connected to the second guide column 63. A groove 631 is provided on the second guide column 63, and the lamp bead 51 is located inside the groove 631. The first guide column 62 is embedded in the light-through hole 23. When the lamp bead 51 emits light, the light is transmitted to the first guide column 62 through the groove 631, so that the light is emitted from the light-through hole 23 through the first guide column 62.
[0048] The mounting frame 60 is also provided with a light guide column 611, which includes a first guide column 62 and a second guide column 63. The first guide column 62 is located on the side of the mounting frame 60 facing the waterproof member 40, and the second guide column 63 is located on the side of the mounting frame 60 facing the circuit board 50, and the first guide column 62 is connected to the second guide column 63. Since the second guide column 63 is provided with a slot 631, and the lamp bead 51 is located inside the slot 631, when the lamp bead 51 emits light, the light can propagate in the slot 631 and enter and be transmitted to the first guide column 62, so that the first guide column 62 can emit light outward. Since the first guide column 62 is embedded in the light through hole 23, after the first guide column 62 receives the light emitted by the lamp bead 51, the first guide column 62 can guide the light through the light through hole 23, so that the light emitted by the lamp bead 51 can be emitted for observation by the user.
[0049] It should be noted that the first guide pillar 62 and the second guide pillar 63 can be made of light-transmitting materials, such as glass, transparent plastic such as acrylic, etc. The specific material of the first guide pillar 62 and the second guide pillar 63 is not specifically limited in the embodiment of the utility model.
[0050] For ease of manufacturing, the mounting frame 60, the first guide column 62, and the second guide column 63 can be manufactured in an integrated manner, so that the mounting frame 60, the first guide column 62, and the second guide column 63 are an integrated structure, making the connection between the mounting frame 60, the first guide column 62, and the second guide column 63 more stable.
[0051] In addition, in some embodiments, Figure 3 , Figure 4 , Figure 5 As shown, the number of light guide columns 611 and lamp beads 51 can be multiple, the second guide column 63 is opposite to the lamp bead 51, and a gap 64 is provided between the first guide columns 62 of two adjacent light guide columns 611. A light shielding component 65 can also be connected to the waterproof component 40, and the light shielding component 65 is located between the mounting frame 60 and the keycap 10. A plurality of through holes 651 are provided on the light shielding component 65, the first guide column 62 is penetrated through the through hole 651, and part of the first guide column 62 extends out of the through hole 651, and part of the first guide column 62 extending out of the through hole 651 is embedded in the light through hole 23, the light shielding component 65 is in contact with the shell 20, and the part of the light shielding component 65 without the through hole 651 seals the gap 64 between adjacent first guide columns 62.
[0052] There are multiple light guide posts 611, and there is a gap 64 between the first guide posts 62 of two adjacent light guide posts 611. The light emitted by the lamp bead 51 can propagate to the gap 64 between the first guide posts 62. At this time, the light may be confused, disrupting the light emission of the light-through hole 23, so that the light emission observed by the user is inconsistent with the actual light emission. For example, when one of the lamp beads 51 emits light, the light can propagate in the slot 631 of the opposite second guide post 63, and propagate to the first guide post 62 connected to the second guide post 63. The first guide post 62 can guide the light into a light-through hole 23 embedded therein. At the first guide post 62, another first guide post 62 adjacent thereto can also receive the light and guide the light into another light-through hole 23. At this time, one lamp bead 51 can make multiple light-through holes 23 emit light, which will affect the user's perception.
[0053] In the embodiment of the utility model, a shading member 65 may be connected to the waterproof member 40, and the shading member 65 is located between the mounting frame 60 and the keycap 10. Since a plurality of through holes 651 are provided on the shading member 65, the first guide column 62 may be passed through the through hole 651, and part of the first guide column 62 may extend from the through hole 651 and be embedded in the light-through hole 23, so that the first guide column 62 can normally guide light into the light-through hole 23, so that the light-through hole 23 can emit light normally. Since the shading member 65 is in contact with the shell 20, the portion of the shading member 65 where the through hole 651 is not provided can seal the gap 64 between adjacent first guide pillars 62. At this time, after the lamp bead 51 emits light, the light can propagate in the corresponding second guide pillar 63 and the first guide pillar 62, and emit light through the light-through hole 23. When the light is transmitted to the gap 64 between the adjacent first guide pillars 62, the shading member 65 can block the light to prevent the light from propagating to the adjacent first guide pillars 62, thereby preventing the problem of light emitted by different lamp beads 51 from mixing.
[0054] It should be noted that the waterproof component 40 and the light-shielding component 65 can be integrally formed by injection molding. For example, the waterproof component 40 can be made of waterproof rubber and other materials, and the light-shielding component 65 can be made of waterproof and light-shielding rubber material by two-color injection molding; or the waterproof component 40 and the light-shielding component 65 can both be made of waterproof and light-shielding rubber material by injection molding at one time, which can reduce the difficulty of manufacturing.
[0055] It should also be noted that, when there are multiple light guide columns 611 and multiple lamp beads 51, the light guide columns 611 and the lamp beads 51 can be distributed in different ways. For example, multiple lamp beads 51 can be distributed at intervals along the circumferential direction of the mounting hole 22. Correspondingly, multiple light guide columns 611 are also arranged around the mounting hole 22, that is, in the first direction X, the projections of the multiple lamp beads 51 and the projections of the multiple light guide columns 611 both surround the projection of the mounting hole 22; or, the multiple lamp beads 51 and the multiple light guide columns 611 can also be distributed at intervals along the direction intersecting with the first direction X.
[0056] Specifically, when multiple lamp beads 51 and multiple light guide columns 611 can be spaced apart along the circumferential direction of the mounting hole 22, the lamp beads 51 and the light guide columns 611 can be arranged according to the mounting hole 22. For example, when the mounting hole 22 is a circular hole, the lamp beads 51 and the light guide columns 611 can be arranged outside the mounting hole 22 along an arc-shaped trajectory, wherein the arc-shaped trajectory can be a whole circle or a part of a circle; when the mounting hole 22 is a rectangular hole, the lamp beads 51 and the light guide columns 611 can be spaced apart along the length direction or width direction of the rectangle, or can be arranged around a circle of the long hole; when the mounting hole 22 is a waist-shaped hole, the lamp beads 51 and the light guide columns 611 can be spaced apart along the length direction of the waist-shaped hole, or can be spaced apart along the arc-shaped extension direction of the end of the waist-shaped hole, or can be arranged around a circle of the waist-shaped hole.
[0057] In addition, in some embodiments, Figure 2 , Figure 6 As shown, a mounting member 41 may be provided on the surface of the waterproof member 40 facing the circuit board 50, and the mounting member 41 is extended along the circumferential direction of the waterproof member 40. A mounting groove 66 is also provided on the surface of the mounting frame 60 away from the circuit board 50, and the mounting groove 66 extends along the circumferential direction of the mounting frame 60. The mounting groove 66 is opposite to the mounting member 41, and the mounting member 41 is embedded in the mounting groove 66.
[0058] The surface of the waterproof member 40 facing the circuit board 50 is also provided with a mounting member 41, and the mounting member 41 is extended along the circumferential direction of the waterproof member 40, that is, the mounting member 41 can be arranged in a circle on the waterproof member 40; the surface of the mounting frame 60 away from the circuit board 50 is also provided with a mounting groove 66, and the mounting groove 66 extends along the circumferential direction of the mounting frame 60, that is, the mounting groove 66 can also be arranged in a circle on the waterproof member 40. Since the mounting groove 66 is opposite to the mounting member 41, the mounting member 41 can be embedded in the mounting groove 66, which can make the connection between the waterproof member 40 and the mounting frame 60 more stable. The mounting member 41 is embedded in the mounting groove 66, and the mounting groove 66 can also limit the mounting member 41, so that the position of the waterproof member 40 is relatively fixed, thereby preventing the waterproof member 40 from moving on the mounting frame 60, causing the waterproof member 40 to be misaligned with the mounting hole 22, resulting in poor waterproof effect at the mounting hole 22; on the other hand, the waterproof member 40 and the mounting member 41 can be sealed to prevent moisture from passing through the mounting hole 22 and entering between the waterproof member 40 and the mounting member 41, and entering the circuit board 50 to damage the components on the circuit board 50.
[0059] In addition, in some embodiments, Figure 2 , Figure 6 As shown, the mounting hole 22 may include a countersunk hole portion 221 and a through hole portion 222 that are interconnected. The countersunk hole portion 221 is close to the touch switch 30. A boss 11 may be provided on the peripheral wall of the keycap 10. The boss 11 extends in the circumferential direction of the keycap 10, and the boss 11 is embedded in the countersunk hole portion 221.
[0060] The mounting hole 22 includes a countersunk hole portion 221 and a through hole portion 222, wherein the countersunk hole portion 221 is located on a side close to the touch switch 30, and the through hole portion 222 is located on a side away from the touch switch 30. Since the countersunk hole portion 221 and the through hole portion 222 are connected to each other, the aperture of the countersunk hole portion 221 is larger than that of the through hole portion 222, and the countersunk hole portion 221 can provide a clamping position for the keycap 10, so as to install the keycap 10. Specifically, a boss 11 is provided on the peripheral wall of the keycap 10, and the boss 11 extends in the circumferential direction around the keycap 10, so that the boss 11 can be embedded in the countersunk hole portion 221, and at this time, the connection between the countersunk hole portion 221 and the through hole portion 222 can also abut against the side of the boss 11 away from the touch switch 30, and the boss 11 is limited, so that the problem of the keycap 10 coming out of the mounting hole 22 along the side away from the touch switch 30 can be avoided. On the side of the keycap 10 facing the touch switch 30 , the keycap 10 abuts against the waterproof component 40 and can be limited by the waterproof component 40 .
[0061] That is, the present application sets a boss 11 on the peripheral wall of the keycap 10, and the boss 11 can be embedded in the countersunk hole. The surface of the boss 11 facing away from the touch switch 30 abuts against the bottom of the countersunk hole portion 221, and the part of the keycap 10 located on the side of the boss 11 facing away from the touch switch 30 is embedded in the through hole portion 222. The setting of the boss 11 and the countersunk hole portion 221 can limit the keycap 10 to prevent the keycap 10 from moving to the side away from the touch switch 30, and can prevent the keycap 10 from falling out of the mounting hole 22.
[0062] In addition, in some embodiments, a recessed portion 42 may be provided on the waterproof component 40, and the recessed portion 42 is recessed along the direction from the keycap 10 to the touch switch 30, the recessed portion 42 is opposite to the touch switch 30, the surface of the boss 11 facing away from the touch switch 30 abuts against the bottom of the countersunk hole portion 221, and the surface of the boss 11 facing the touch switch 30 abuts against the waterproof component 40, a portion of the keycap 10 located on the side of the boss 11 facing away from the touch switch 30 is embedded in the through hole portion 222, and a portion of the keycap 10 located on the side of the boss 11 facing the touch switch 30 is embedded in the recessed portion 42.
[0063] A recessed portion 42 is provided on the waterproof component 40, and the recessed portion 42 is recessed along the direction from the keycap 10 to the touch switch 30. The recessed portion 42 is opposite to the touch switch 30, and the boss 11 is in contact with the waterproof component 40 toward the surface of the touch switch 30. The waterproof component 40 can also limit the keycap 10 to prevent the keycap 10 from moving toward the side close to the touch switch 30, and can prevent the keycap 10 from moving inward from the mounting hole 22 and falling into the mounting cavity 21. In the present application, part of the keycap 10 is embedded in the through hole 222, and part of the keycap 10 is embedded in the recess 42. The boss 11 on the peripheral wall of the keycap 10 is embedded in the countersunk hole 221. The through hole 222, the recess 42, and the countersunk hole 221 can limit the keycap 10 to prevent the keycap 10 from moving on the surface of the waterproof member 40 toward the keycap 10, thereby limiting the keycap 10 in all directions and installing the keycap 10. That is, in the embodiment of the present utility model, the keycap 10 can be located between the housing 20 and the recess 42. The setting of the housing 20 and the waterproof member 40 can limit the keycap 10, which is convenient for installing the keycap 10.
[0064] Furthermore, since the waterproof member 40 is provided with a recessed portion 42, and the recessed portion 42 is recessed in the direction from the keycap 10 to the touch switch 30, the recessed portion 22 is close to the touch switch 30, and the recessed portion 42 can also increase the installation space for the keycap 10, so that the keycap 10 is located between the housing 20 and the recessed portion 42, and the keycap 10 is close to the touch switch 30. When the keycap 10 is pressed, the keycap 10 moves a short distance to push the waterproof member 40 to abut against the touch switch 30, so that the key structure 100 responds more quickly.
[0065] In the related art, the keycap 10 is usually installed on the key structure 100 through a fusion structure. After long-term use, the fusion structure may be damaged, causing the keycap 10 to loosen and cause the key structure 100 to make abnormal sounds. Even after the fusion structure breaks, it loses the installation function of the keycap 10, causing the keycap 10 to fall inside the installation cavity 21, thereby causing the key structure 100 to lose its control function. The embodiment of the utility model uses the housing 20 and the waterproof member 40 to install the keycap 10, avoiding the problem of using the fusion structure to install the keycap 10, which is easy to be damaged or broken.
[0066] In the embodiment of the utility model, the key structure 100 includes a keycap 10, a housing 20, a touch switch 30 and a waterproof member 40, wherein the housing 20 has an installation cavity 21 inside, and the keycap 10, the waterproof member 40 and the touch switch 30 can all be arranged in the installation cavity 21 and distributed along the first direction X. The housing 20 is also provided with an installation hole 22 extending along the first direction X. Since the installation hole 22 is connected to the installation cavity 21, a part of the keycap 10 can be embedded in the installation hole 22, so that the keycap 10 can extend from the installation cavity 21, so that the user can operate the keycap 10. Since the keycap 10 can move along the first direction X relative to the mounting hole 22, and the waterproof component 40 abuts against the keycap 10, the keycap 10 can be operated to move in the mounting hole 22 to move along the first direction X, so that the keycap 10 can drive part of the waterproof component 40 to move toward the direction close to the touch switch 30, or drive part of the waterproof component 40 to move away from the touch switch 30, so that the waterproof component 40 can abut against or separate from the touch switch 30, that is, the keycap 10 can operate the touch switch 30 through the waterproof component 40, so that the touch switch 30 can switch the on and off states, thereby realizing the function of the key structure 100. At least a portion of the waterproof member 40 facing the keycap 10 abuts against the housing 20. Since the waterproof member 40 covers the mounting hole 22, the waterproof member 40 can block the mounting hole 22 and block the moisture passing through the mounting hole 22, thereby preventing the moisture from outside from passing through the keycap 10 and the waterproof member 40 to reach the touch switch 30, causing the touch switch 30 to work abnormally, and preventing the key structure 100 from malfunctioning. When the key structure 100 is used in an electrical device, it can also prevent moisture from entering the electrical device through the mounting hole 22 and affecting the function of the electronic device.
[0067] In addition, an embodiment of the utility model further provides an electrical device, and the electrical device includes the key structure 100 in any one of the above embodiments.
[0068] For an electrical device provided with the above-mentioned button structure 100, the waterproof component 40 can cover the mounting hole 22 to achieve a waterproof effect at the mounting hole 22, and can prevent moisture from entering the interior of the electrical device through the position where the keycap 10 is set at the button structure 100, thereby preventing the problem of affecting the function of the electronic device.
[0069] It should be noted that the electrical device can be any device that can be provided with a key structure 100, including but not limited to mobile phones, tablet computers, power banks, smart watches and other terminals. The specific type of the electrical device is not specifically limited in the embodiments of the present utility model.
[0070] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
