[0033] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0034] Figure 1 and Figure 2The key assembly 100 of an embodiment of the utility model is shown, and the key assembly 100 includes a housing 101, a key 104 and a circuit board 106, and the circuit board 106 includes a light source 108. The housing 101 includes a rear housing 102 and a front housing 103, and the rear housing 102 and the front housing 103 are detachably connected. For example, the rear housing 102 and the front housing 103 are mutually clamped; for another example, the rear housing 102 and the front housing 103 are connected by screws. The rear housing 102 and the front housing 103 are mutually connected to form a cavity. The circuit board 106 is connected to the rear housing 102 or the front housing 103, and the circuit board 106 is located in the cavity, and accordingly, the light source 108 is also located in the cavity. The light source 108 can be set as an LED lamp bead. The key 104 can be light-transmissive, for example, the key 104 can be made of a transparent or translucent material. More specifically, the key 104 can be made of a transparent or translucent plastic. The button 104 is movably connected to the housing 101. Therefore, when the user presses the button 104, the button 104 can move relative to the housing 101. Figure 3 As shown, the button 104 includes a pressing portion 202 and a light guide portion 201. The pressing portion 202 is the portion of the button 104 that is pressed by the user, and at least a portion of the pressing portion 202 is located outside the housing 101. The light guide portion 201 is used to guide the light emitted by the light source 108 to the pressing portion 202, and at least a portion of the light guide portion 201 is located inside the housing 101. The light guide portion 201 includes a light input end and a light output end, which are sequentially arranged along a first direction, and the light output end is connected to the pressing portion 202. Figure 4 For example, the first direction may be from bottom to top, the light input end is the bottom end of the light guide portion 201, and the light output end is the top end of the light guide portion 201. Figure 4 As shown, the light source 108 includes a light emitting surface 110, and the light emitted by the light source 108 is emitted from the light emitting surface 110, and the light emitting surface 110 faces the light input end (the bottom end of the light guide portion 201). The light emitting surface 110 and the light guide portion 201 are arranged in sequence along the second direction, and the first direction and the second direction are perpendicular. Figure 4 , the second direction is from left to right. Figure 4 The dashed line with an arrow in the middle indicates the transmission path of a portion of the light emitted by the light source 108. The light will be reflected, refracted and scattered inside the key 104. After the light enters the light guide portion 201 from the light inlet end, it will subsequently pass through the light outlet end and the pressing portion 202, and the light will eventually be emitted from the pressing portion 202. It should be noted that the light emitted from the right end surface of the pressing portion 202 is only a portion of the light emitted from the pressing portion 202, and the light can also be emitted from the top surface, bottom surface, front side surface, rear side surface and other positions of the pressing portion 202.

[0035] In the prior art, the light of the light source 108 is usually emitted straight from the light source 108 to the pressing portion 202. For example, if the light is required to be emitted from the right end surface of the pressing portion 202, the light source 108 will be directly opposite to the left end surface of the pressing portion 202, and the light will be emitted straight from left to right. In this way, when the user observes the right end surface of the pressing portion 202, the area of ​​the right end surface opposite to the light source 108 will be brighter (this area will form a brighter light spot), and the rest of the right end surface will be relatively dark. The uneven brightness of the right end surface may even produce a dazzling lighting effect.

[0036] As for the key assembly 100 of the present invention, since the light source 108 and the light-inlet end of the light-guiding portion 201 are arranged facing each other and the light-emitting end of the light-guiding portion 201 is connected to the pressing portion 202, the light source 108 and the pressing portion 202 are staggered, and the light-emitting surface 110 of the light source 108 is not directly opposite to the pressing portion 202. In addition, the light of the light source 108 enters the pressing portion 202 through the light-guiding portion 201, and the degree of tortuosity of the light transmission path is relatively high. The light undergoes more reflections, refractions and scattering during the transmission process, and the light finally emitted from the pressing portion 202 is relatively dispersed and relatively uniform, and the brightness uniformity of the surface of the pressing portion 202 is relatively high, and it is not easy to have a situation of local over-brightness.

[0037] exist Figure 3 In the illustrated embodiment, the light guide portion 201 and the pressing portion 202 are both flat, and the light guide portion 201 and the pressing portion 202 are perpendicular to each other. In other embodiments, the angle between the light guide portion 201 and the pressing portion 202 may also be an obtuse angle or an acute angle.

[0038] like Figure 4 As shown, in some embodiments, the side surface of the light guide portion 201 facing the light emitting surface 110 is the first surface 204, the side surface of the light guide portion 201 facing away from the light emitting surface 110 is the second surface 205, and at least a portion of the pressing portion 202 protrudes relative to the second surface 205 (protrudes along the second direction). The key 104 also includes a connecting portion 203, the connecting portion 203 is connected to the second surface 205 and protrudes relative to the second surface 205 (protrudes along the second direction), and the connecting portion 203 is also connected to the pressing portion 202. In short, the key 104 has a corner, which is formed by connecting the light guide portion 201 and the pressing portion 202, and the connecting portion 203 is arranged at the corner. The connecting portion 203 can also allow light to pass through, and the connecting portion 203 is used to increase the path width for light to pass through at the corner, so as to facilitate the transmission of light from the light guide portion 201 to the portion of the pressing portion 202 protruding relative to the second surface 205.

[0039] like Figure 3As shown, in some embodiments, the connecting portion 203 is in the shape of a triangular pyramid, the outer surface of the connecting portion 203 includes a connecting bevel 206, the second surface 205 and the pressing portion 202 are both connected to the connecting bevel 206, the angle between the connecting bevel 206 and the pressing portion 202 is an obtuse angle, and the angle between the connecting bevel 206 and the second surface 205 is an obtuse angle. This arrangement allows light to be more smoothly transmitted from the light guide portion 201 to the portion of the pressing portion 202 protruding relative to the second surface 205. More specifically, in one embodiment, the angle between the connecting bevel 206 and the bottom surface of the pressing portion 202 can be 135°, and the angle between the connecting bevel 206 and the second surface 205 can be 135°. However, these two angles do not need to be equal, nor are they limited to 135°, as long as these two angles are obtuse angles. In addition, the connecting portion 203 can also be set to other shapes, such as a quadrangular prism, a cylindrical shape, and the like.

[0040] like Figure 2 As shown, in some embodiments, the circuit board 106 of the key assembly 100 further includes a switch 107, which is a contact switch. The switch 107 includes a fixing base 111 and a contact 112 that can move relative to the fixing base 111. The key 104 can move relative to the housing 101 to switch between the first position and the second position. Figure 6 In, the button 104 is in the second position; in Figure 7 In the embodiment, the button 104 is in the first position. It should be noted that, Figure 6 and Figure 7 The selected sections are the same, but Figure 6 and Figure 4 The selected sections are different. Figure 7 As shown, when the button 104 is in the first position, the light guide portion 201 presses the contact 112; Figure 6 As shown, when the button 104 is in the second position, the light guide 201 releases the pressure on the contact 112. After the contact 112 is pressed, the circuit board 106 will send a specific signal to the outside, so that the device electrically connected to the button assembly 100 performs a corresponding action. For example, after the switch 107 is pressed once, the heater in the seat of the toilet is turned on; after the switch 107 is pressed again, the heater is turned off. It should be noted that the light guide 201 can press the switch 107 directly or indirectly. The light guide 201 directly presses the switch 107, which means that the light guide 201 directly abuts against the switch 107. The light guide 201 indirectly presses the switch 107, which means that the light guide 201 abuts against an intermediate component (such as the reset component 105 described below), and the intermediate component abuts against the switch 107.

[0041] In this embodiment, the light guide 201 is used to guide light to the pressing portion 202 and to press and trigger the switch 107. The button 104 does not need to be provided with an additional part specifically for pressing the switch 107, which is conducive to reducing the structural complexity of the button 104 and reducing the manufacturing difficulty and cost of the button 104.

[0042] In some embodiments, the button 104 is rotatably connected to the housing 101. For example, the button assembly 100 further includes a shaft 109, which passes through the rear shell 102 of the housing 101 and the button 104, and the button 104 can rotate around the shaft 109. In the case where the button assembly 100 includes multiple buttons 104, one shaft 109 can pass through multiple buttons 104 at the same time. The outer surface of the pressing portion 202 includes a pressing surface 207, which faces away from the light guide portion 201, and the pressing surface 207 can be the top surface of the pressing portion 202. Please refer to the following figure for details. Figure 6 and Figure 7 When the pressing surface 207 is pressed (for example, by a user's finger), the light guide portion 201 can rotate in a direction close to the switch 107, and the button 104 can move from the second position to the first position. In other embodiments not shown, the movement mode of the button 104 can also be set to move, for example, after the pressing portion 202 is pressed, the button 104 can move downward.

[0043] like Figure 2 As shown, in some embodiments, the button assembly 100 further includes an elastic restoring member 105, which is connected to the button 104, and the elastic force of the restoring member 105 is used to move the button 104 from the first position to the second position. In this way, when the user releases the pressing portion 202, the restoring member 105 can automatically restore the button 104.

[0044] The reset member 105 can be configured as an elastic silicone pad, or as a spring or a torsion spring. The following first describes the matching relationship between the reset member 105 and the button 104 and the switch 107 when the reset member 105 is configured as a silicone pad. Figure 5 The key assembly 100 is shown in a state after the front shell 103 and the key 104 are removed. The reset member 105 includes a base portion 301 and a boss portion 302. The base portion 301 is connected to the fixing seat 111, and the boss portion 302 protrudes relative to the base portion 301 (protrudes along the second direction). Figure 6 As shown, a receiving groove 304 is formed on a side of the boss portion 302 facing away from the first surface 204, and at least a portion of the contact 112 is disposed in the receiving groove 304. Figure 7 As shown, when the button 104 is in the first position, the first surface 204 abuts against the convex surface, and the inner wall surface of the receiving groove 304 abuts against the contact 112, so that the light guide 201 indirectly presses the contact 112 of the switch 107. Figure 6As shown, when the button 104 is in the second position, the inner wall surface of the receiving groove 304 is spaced apart from the contact 112, and the contact 112 is not pressed by the light guide 201. The boss portion 302 is hollow, and the boss portion 302 can be elastically deformed after being squeezed. When the user releases the pressing portion 202, the elastic force of the boss portion 302 is used to push the light guide 201, so that the button 104 rotates, and then the button 104 moves from the first position to the second position.

[0045] like Figure 2 As shown, the button assembly 100 may include a plurality of buttons 104 and a plurality of switches 107, and the buttons 104 and the switches 107 are arranged in a one-to-one correspondence. The one-to-one correspondence between the buttons 104 and the switches 107 means that the number of buttons 104 is the same as the number of switches 107, each button 104 is used to trigger a switch 107, and each switch 107 is only triggered by one button 104. It should be noted that the states of any two buttons 104 are independent of each other, and the movement of one button 104 will not cause the other button 104 to move synchronously. Figure 5 As shown, the reset member 105 includes a plurality of bosses 302, and the bosses 302 are arranged in a one-to-one correspondence with the switches 107. The one-to-one correspondence between the bosses 302 and the switches 107 means that the number of the bosses 302 is the same as the number of the switches 107, each boss 302 is sleeved on the outside of a contact 112, and each contact 112 is only sleeved by one boss 302. The base 301 and the plurality of bosses 302 are integrally formed. In this way, a reset member 105 can be used to drive multiple buttons 104 to reset, and the number of parts of the button assembly 100 is small, which is conducive to improving the assembly convenience of the button assembly 100.

[0046] The base portion 301 can also separate the light guide portion 201 from certain circuits or certain devices on the circuit board 106 to prevent the light guide portion 201 from directly colliding with the circuit board 106 and thus damaging the circuits or devices. Figure 5 As shown, the base portion 301 is provided with an avoidance through hole 303, and the avoidance through hole 303 is arranged opposite to the light emitting surface 110. The avoidance through hole 303 and the light emitting surface 110 are arranged opposite to each other, which means that when observed along the axial direction of the avoidance through hole 303 (for example, observed from right to left), the light emitting surface 110 is completely located within the edge of the avoidance through hole 303. The avoidance through hole 303 allows light to pass through, so that the light is emitted from the light emitting surface 110 to the light guide portion 201.

[0047] In other embodiments, the reset member 105 may also be configured as a spring. For example, one end of the spring abuts against the inner wall surface of the housing 101, and the other end of the spring abuts against the first surface 204 of the light guide 201. When the button 104 is in the first position, the spring is in a compressed state; after the user releases the pressing portion 202, the elastic force of the spring pushes the button 104 to rotate, so that the button 104 moves from the first position to the second position. In other embodiments, the reset member 105 may also be configured as a torsion spring, which is sleeved on the outside of the rotating shaft 109, one end of the torsion spring is connected to the housing 101, and the other end of the torsion spring is connected to the button 104; after the user releases the pressing portion 202, the elastic force of the torsion spring pushes the button 104 to move from the first position to the second position.

[0048] The present invention also provides a smart cover, which may include the button assembly 100 described above. The user can enable certain functions of the smart cover by pressing the pressing portion 202 of the button 104, which include but are not limited to automatic closing, automatic opening, seat heating, cleaning, etc. The present invention also provides a toilet, which may include the above-mentioned smart cover. In addition, the button assembly 100 may also be applied to a toilet that does not have a smart cover. When the button assembly 100 is applied to a toilet, the button assembly 100 is not necessarily applied to the smart cover. The button assembly 100 may be applied to other parts of the toilet that need to be triggered by the button 104.

[0049] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
