Detailed Description

In order to make the technical scheme and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail with reference to the accompanying drawings.

Currently, electronic devices such as sockets, remote controllers, mobile phones and the like are provided with buttons, and the buttons and micro switches are matched to form button switches for controlling the operation of the electronic devices. The indication lamp and the button switch are combined, so that the button switch can be endowed with a luminous function, and different operation states of the electronic device can be indicated by utilizing light.

The indicator lights can emit different colors, such as red, yellow, green, blue, white, etc., and indicate that the electronic device is in a specific working state through a specific color; or, the electronic device is respectively in different working states by turning on and off the indicator light. For example, the button is pressed to enable the indicator lamp to be lighted, so that the button emits light to represent that the timing function of the socket is started; the indicator lights are extinguished, indicating that the receptacle power is turned off.

The related art provides a button capable of transmitting light, comprising: a pressing portion, a light transmitting portion, and an elastic portion; the pressing part is in a disc shape, the light transmission part is in an annular structure connected with the side wall of the pressing part and is used for transmitting light, and the pressing part and the light transmission part are integrally positioned in the button through hole; one end of the elastic part is connected with the side wall of the light-transmitting part, and the other end of the elastic part is connected with the shell of the electronic device and is used for providing elastic restoring force for the button. When the indicator lamp of the electronic device is lighted, the light can be transmitted out of the light transmission part, and can be transmitted out of a gap between the button and the button via hole easily, so that the light is not gathered, and meanwhile, the user experience is poor.

The embodiment of the invention provides a button 1, as shown in fig. 1, the button 1 comprises: a pressing portion 11, a light shielding portion 12, and an elastic portion 13; wherein, the pressing part 11 includes: the pressing surface wall 111 and the pressing side wall 112, and the pressing surface wall 111 can transmit light.

The first end of the pressing side wall 112 is connected with the periphery of the pressing surface wall 111, and the pressing side wall 112 and the pressing surface wall 111 cooperate to form a light guide cavity 113; the second end of the pressing sidewall 112 is connected to the light shielding portion 12, and the light shielding portion 12 is configured to prevent light from leaking out of the light guide cavity 113; the first end of the elastic portion 13 is connected to the outside of the pressing sidewall 112, and the second end of the elastic portion 13 is used for being connected to the housing 2 of the electronic device.

The button 1 provided by the embodiment of the invention is suitable for an electronic device and is connected with the shell 2 of the electronic device when in application. The pressing portion 11 of the button 1 includes a pressing surface wall 111 and a pressing side wall 112, which cooperate to form a light guide cavity 113, so that when the indicator light of the electronic device emits light, the light enters the light guide cavity 113 and is transmitted through the pressing surface wall 111. Through setting up shading portion 12, can prevent that light from leaking by light guide cavity 113, make the lamp light only can be by pressing down the face wall 111 and show through, ensured light concentration degree, improved user experience simultaneously. By providing the elastic portion 13, an elastic restoring force is provided to the button 1 so that the button 1 can be automatically restored after being pressed.

In the embodiment of the present invention, the light shielding portion 12 is connected to the second end of the pressing sidewall 112, that is, the light shielding portion 12 is connected to the end of the pressing sidewall 112 away from the pressing surface wall 111, and the light shielding portion 12 is configured to prevent the light from leaking out of the light guiding cavity 113. In some possible implementations, as shown in fig. 1, the inner side of the light shielding part 12 has an indicator light receiving cavity 121, the indicator light receiving cavity 121 communicates with the light guide cavity 113, and the indicator light receiving cavity 121 is used to receive an indicator light of an electronic device.

The indicator light receiving chamber 121 is to receive at least a light emitting portion of the indicator light, as long as any structure capable of forming the indicator light receiving chamber 121 is suitable for the light shielding portion 12, such as arc, angle, and other common regular or irregular geometric shapes.

For example, the light shielding portion 12 is of an arc-shaped plate-like structure (e.g., a semicircular plate) that is easily molded and prepared, and the bending direction of the light shielding portion 12 is set around the indicator lamp, so that the inside of the light shielding portion 12 is formed with an indicator lamp accommodating chamber 121 of an arc-shaped structure inside which the indicator lamp is located.

The length of the light shielding portion 12 is determined according to the length of the indicator lamp, and at least the light emitting portion of the indicator lamp is ensured to be entirely located in the indicator lamp housing chamber 121.

When the indicator lights emit light, the light is blocked by the wall of the shading part 12 and directly enters the light guide cavity 113, so that the light is effectively prevented from leaking. Because the button via hole 21 is necessarily arranged on the casing 2 of the electronic device to accommodate the button 1 capable of performing pressing movement, a gap may exist between the button 1 and the button via hole 21, and the light shielding part 12 is arranged in the embodiment of the invention, so that light can be effectively prevented from being transmitted out of the gap between the button 1 and the button via hole 21.

With respect to the pressing portion 11, the pressing side wall 112 is disposed around the periphery of the pressing surface wall 111, so that the light guiding cavity 113 formed by the cooperation of the pressing side wall 112 and the pressing surface wall 111 has only one opening for the light to enter, and the rest of the light guiding cavity 113 is closed, so that the light in the light guiding cavity 113 can be gathered and finally transmitted out from the pressing surface wall 111.

The structure of the pressing face wall 111 includes, but is not limited to: the structure of the pressing side wall 112 is adapted to the structure of the pressing surface wall 111 by ensuring that the pressing side wall 112 and the pressing surface wall 111 are matched to form the semi-closed light guide cavity 113. For example, the pressing surface wall 111 is a circular plate shape that is easy to be formed, the pressing side wall 112 is a cylinder shape that is easy to be formed, and the light guide cavity 113 formed by combining the pressing surface wall 111 and the pressing side wall is a cylinder shape.

In some possible implementations, as shown in fig. 2, pressing the sidewall 112 includes: a side support 1121 and a bottom support 1122, wherein a first end of the side support 1121 is connected to the pressing surface wall 111, a second end of the side support 1121 is connected to the light shielding portion 12, and the bottom support 1122 is sleeved outside the second end of the side support 1121. For example, when the side support 1121 is a cylindrical structure, the bottom support 1122 is a circular ring structure. By providing the bottom support 1122, on the one hand, the strength of the pressing side wall 112 can be increased, and further, the strength of the connection between the elastic portion 13 and the pressing side wall 112 can be improved, and on the other hand, the button 1 can be easily manufactured by an injection molding process.

In some possible implementations, as shown in fig. 1, the pressing surface wall 111 includes: the light transmitting region 1111 and the light non-transmitting region 1112, so that the light enters the light guiding cavity 113 and is transmitted out from the light transmitting region 1111 of the pressing surface wall 111, which is advantageous for further improving the light concentration. The location distribution for both the light transmissive region 1111 and the non-light transmissive region 1112 includes, but is not limited to, the following implementations:

(1) The non-light-transmitting region 1112 is disposed around the periphery of the light-transmitting region 1111, for example, the light-transmitting region 1111 is located at the middle position of the pressing surface wall 111 (see fig. 2). The structure of the light transmitting region 1111 includes, but is not limited to: circular, square, polygonal, star-shaped, lamp-shaped or other geometric figures of identification having indicative significance.

(2) The light-transmitting region 1111 is surrounded on the periphery of the light-transmitting region 1111, and for example, the light-non-transmitting region 1112 is located at the middle position of the pressing surface wall 111. The structure of the light transmitting region 1111 includes, but is not limited to: annular or other geometric indicia of indicative significance.

(3) The light transmitting region 1111 is provided in a plurality of places (two places or more) separated by the light non-transmitting region 1112, and the light transmitting region 1111 and the light non-transmitting region 1112 can be mated to form a plurality of types of geometric figures.

The transparent region 1111 and the non-transparent region 1112 of the pressing surface wall 111 may be made of the same material, or may be made of different materials, so long as the transparent region 1111 is ensured to be transparent, and the non-transparent region 1112 is not transparent.

In some possible implementations, the transparent region 1111 is made of the same material as the non-transparent region 1112, and the wall thickness of the transparent region 1111 is smaller than the thickness of the non-transparent region 1112 (see the partial cross-section in the oval frame line of fig. 1). With this implementation, when the pressing surface wall 111 is formed, the wall of the light transmitting region 1111 is thinned (the pressing surface wall 111 is partially thinned), so that the thickness thereof reaches a thickness capable of transmitting light, thereby realizing light transmission. Through the implementation manner, the strength of the pressing surface wall 11 can be ensured, the preparation difficulty of the pressing part 11 can be obviously reduced, the preparation flow of the pressing part 11 is simplified, and meanwhile, the structure of the button 1 can be simplified.

For such implementation, the pressing portion 11 is exemplarily prepared by integrally molding the pressing surface wall 111 and the pressing side wall 112.

In order to further improve the shielding effect of the non-transparent area 1112 on the lamplight, in the embodiment of the present invention, the surface of the non-transparent area 1112 is provided with a light shielding coating (the coating is not shown in the figure). Illustratively, the light-shielding ink is pad-printed to the upper surface of the pressing face wall 111 by a pad printing process to obtain a light-shielding coating. Thus, the light of the indicator lamp is only transmitted out through the light-transmitting area 1111, and the light is effectively shielded by the light-non-transmitting area 1112, so that the user experience is improved.

In some possible implementations, the button 1 is prepared using an injection molding process, as follows: a base material is provided, and the pressing portion 11 is obtained by hollowing out the inside of the base material by injection molding.

In another aspect, an embodiment of the present invention further provides an electronic device, for example, a socket shown in fig. 3, where the electronic device includes: any of the above buttons 1, a housing 2 and a function member 3 having an indicator light. Wherein, the shell 2 is provided with a button via hole 21, and the pressing part 11 of the button 1 can be movably positioned in the button via hole 21 in a pressing way; the second end of the elastic part 13 of the button 1 is connected with the housing 2; as shown in fig. 4, the functional element 3 with the indicator light 31 is located inside the housing 2. The button 1 is linked to the function element 3, that is, the button 1 is pushed to act on the function element 3 to perform a specific functional operation.

According to the electronic device provided by the embodiment of the invention, based on the use of the button 1, when the indicator lamp 32 emits light, the light enters the light guide cavity 113 and is transmitted out by the light transmission area 1111 of the pressing surface wall 111, and due to the shielding of the light shielding part 12 of the button 1, the light can be prevented from leaking out of the light guide cavity 113, so that the light can be ensured to be transmitted out only by the light transmission area 1111, but not in the gap between the pressing part 11 and the button via hole 21, and the user experience is improved.

The casing 2 of the electronic device is provided with the button via hole 21, the structure of the button via hole 21 is matched with the structure of the pressing part 11 of the button 1, the button via hole 21 and the pressing part are in clearance fit, and the clearance between the button via hole and the pressing part is smaller than 0.5mm, so that the pressing part 11 can be ensured to press in the button via hole 21, and meanwhile, impurities such as dust can be prevented from entering the clearance between the pressing part 11 and the button via hole 21.

For example, when the pressing portion 11 has a cylindrical structure, the button via 21 has a cylindrical structure; when the pressing portion 11 has a hexagonal cylindrical structure, the button via hole 21 has a hexagonal cavity structure.

The button 1 is connected with the housing 2 of the electronic device through the elastic part 13 thereof, wherein the first end of the elastic part 13 is connected with the outer side of the pressing side wall 112 of the pressing part 11, and the second end of the elastic part 13 is connected with the housing 2, so that the elastic part 13 not only can realize the connection between the button 1 and the housing 2, but also can provide elastic restoring force for the button 1, so that the button can be quickly and automatically restored to the original position after being pressed.

As for the connection manner between the elastic portion 13 and the housing 2, including but not limited to: detachable connection, integrally formed connection, etc., as exemplified below:

(1) In some possible implementations, the second end of the elastic portion 13 is detachably connected to the housing 2 of the electronic device, for example, the detachable connection includes: clamping, screw connection, key connection, etc.

In the related art, the connection mode of the elastic part 13 and the shell 2 of the electronic device is hot melting connection, the hot melting process flow is complex, the production assembly efficiency is low, and the production reject ratio is high, but the embodiment of the invention ensures that the detachable connection mode is adopted between the elastic part 13 and the shell 2, so that the operation is simple, the assembly of the button 1 in the electronic device is more convenient and quick, and the improvement of the assembly efficiency and the production reject ratio is facilitated.

When the elastic portion 13 of the button 1 is connected to the housing 2 in a detachable manner, in order to improve the assembly accuracy of the button 1, the button 1 is prevented from being deflected during assembly, as shown in fig. 4, and the button 1 provided in the embodiment of the present invention further includes: the first positioning portion 14, the first positioning portion 14 is connected with the elastic portion 13, and the housing 2 of the electronic device has a second positioning portion 26, and the first positioning portion 14 and the second positioning portion 26 cooperate to form positioning.

The first positioning parts 14 and the second positioning parts 26 have the same number and correspond to each other in position one by one, and the first positioning parts and the second positioning parts are matched with each other to realize positioning.

As an example, the first positioning portion 14 is a convex structure (cylindrical boss, conical boss, etc.), and the second positioning portion 26 is a groove structure (cylindrical groove, conical groove, etc.) that is adapted to the first positioning portion 14.

As another example, the first positioning portion 14 is a groove structure (cylindrical groove, conical groove, etc.), and the second positioning portion 26 is a convex structure (cylindrical boss, conical boss, etc.) that is adapted to the first positioning portion 14.

By arranging as above, when the button 1 is assembled to the housing 2 of the electronic device, the first positioning portion 14 of the button 1 is aligned with and connected to the second positioning portion 26 of the housing 2, so as to realize positioning, thus ensuring that the button 1 is centrally located in the button via 21 of the housing 2 of the electronic device, preventing the problem that the button 1 has a large gap with the button via 21 and a small gap due to deflection, and improving user experience.

For example, the second end of the elastic portion 13 is connected to the housing 2 by a clamping manner, which is not only beneficial to reducing the number of parts, but also convenient to operate.

The manner of engagement between the second end of the elastic portion 13 and the housing 2 will be described with reference to the following example:

As shown in fig. 2, the elastic portion 13 includes: the first elastic arm 131, the second elastic arm 132, the first clip 133 and the second clip 134; the first ends of the first and second elastic arms 131 and 132 are connected to the outer sides of the pressing side walls 112, respectively; the second end of the first elastic arm 131 is connected to the first clip member 133, and the second end of the second elastic arm 132 is connected to the second clip member 134. Further, the housing 2 is further provided with a first assembly hole 22 and a second assembly hole 23, the first assembly hole 22 is internally provided with a first clamping table 24, and the second assembly hole 23 is internally provided with a second clamping table 25; the first clamping table 24 is clamped with the first clamping piece 133, and the second clamping table 25 is clamped with the second clamping piece 134. The first positioning portion 14 is connected to the first elastic arm 131.

The first elastic arm 131 and the second elastic arm 132 are respectively located at opposite outer sides of the pressing sidewall 112, so that the clamping positions of the button 1 and the housing 2 are symmetrically located at two sides of the button 1, and a more stable clamping effect can be obtained.

The first elastic arm 131 and the second elastic arm 132 of the button 1 perform the functions of connection and support, and perform the function of elastic restoration, so that the first elastic arm 131 and the second elastic arm 132 are designed to be elastically deformed only when receiving an external force with a specific threshold value, and the first elastic arm 131 and the second elastic arm 132 are kept in a state of not being elastically deformed when the external force is lower than the specific threshold value, so as to provide sufficient support for the button 1.

In some possible implementations, the first elastic arm 131 and the second elastic arm 132 are different in structure, and the first clip 133 and the second clip 134 are different in structure, so that the clip manner of the first clip 133 and the first clip 24 is different from the clip manner of the second clip 134 and the second clip 25.

As an example, as shown in fig. 5 and 6, the first fitting hole 22 is provided at a distance from the button via hole 21 for accommodating the first clip 133; the second fitting hole 23 communicates with the button via hole 21 for accommodating the second elastic arm 132 and the second clip 134 at the same time. Wherein the first fitting hole 22 and the second fitting hole 23 are respectively located at opposite sides of the button via hole 21.

As shown in fig. 4, the top of the first clamping member 133 has a first guiding surface 1331, the bottom of the first clamping table 24 has a second guiding surface 241, and the first guiding surface 1331 is adapted to the second guiding surface 241, so that the first clamping member 133 passes through the first assembly hole 22 from bottom to top to be clamped with the first clamping table 24. (in the embodiment of the present invention, the pressing surface wall 111 is located in the upper direction and the pressing side wall 112 is located in the lower direction with the pressing portion 11 as a reference.)

For example, the first clamping member 133 includes: the first fastener body, be located the first fixture block at first fastener body top, wherein, the structure of first fastener body includes, but is not limited to: cylindrical, prismatic, rectangular, etc. As shown in fig. 4 or fig. 7, the first fixture block is a trapezoidal block, including: a top surface 1332, an inclined first guide surface 1331, a side surface 1333, and a bottom surface 1334, which are sequentially connected from top to bottom, and the bottom surface 1334 of the first clip block serves as a clipping surface to contact the first clip table 24 for clipping.

The top surface 1332 of the first fixture block and the bottom surface 1334 of the first fixture block extend in a horizontal direction, and are parallel and opposite, the side surface 1333 of the first fixture block extends in a vertical direction, and an included angle between the first guide surface 1331 of the first fixture block and the top surface 1332 is 30 ° -60 °, for example, 45 °.

Correspondingly, as shown in fig. 4, the first clamping platform 24 disposed in the first assembly hole 22 is an inverted trapezoidal block, including: the bottom surface 242, the inclined second guide surface 241, the side surface 243, and the top surface 244 are sequentially connected from bottom to top, and the top surface 244 of the first clamping table 24 is used as a clamping surface to contact with the first clamping piece 133 to achieve clamping.

The top surface 244 and the bottom surface 242 of the first clamping platform 24 extend in a horizontal direction, and are parallel and opposite, the side surface 243 extends in a vertical direction, and an included angle between the second guiding surface 241 and the bottom surface is 30 ° -60 °, for example 45 °.

The second clamping piece 134 is matched with the structure of the second clamping table 25, for example, the second clamping piece 134 is a rectangular block or a trapezoidal block, the second clamping table 25 is a rectangular platform, and the bottom surface 1334 of the second clamping piece 134 is overlapped with the top surface 1332 of the second clamping table 25 so as to realize clamping connection of the two.

For this implementation, when the button 1 is assembled to the housing 2 of the electronic device, the second clamping piece 134 is first passed through the second assembly hole 23 from bottom to top, then the bottom surface 1334 of the second clamping piece 134 is overlapped on the top surface 1332 of the second clamping table 25, so that the clamping between the second clamping piece 134 and the second clamping table 25 is completed, and at this time, the button 1 part of the button 1 also enters into the button via hole 21. Then, the first clamping member 133 is passed through the first assembly hole 22 from bottom to top, in this process, since the first guiding surface 1331 of the first clamping member 133 contacts with the second guiding surface 241 on the first clamping platform 24 and performs guiding, the first clamping member 133 can enter and pass through the first assembly hole 22 along the first clamping platform 24, and finally the bottom surface 1334 of the first clamping member 133 is overlapped on the top surface of the first clamping platform 24, so as to complete the clamping connection between the first clamping member 133 and the first clamping platform 24, and further realize the assembly of the button 1 onto the housing 2 of the electronic device.

In the above-described example, the first fitting hole 22 is provided at a distance from the button via hole 21, and the first fitting hole 22 is used only to accommodate the first clip 133, so that the clip between the first clip 133 and the first clip 24 can be more stable. By communicating the second fitting hole 23 with the button via hole 21, the second fitting hole 23 is for accommodating the second elastic arm 132 and the second clip 134, the fitting efficiency of the button 1 can be improved.

It can be seen that, for the above-mentioned clamping manner, the structural design of the first clamping member 133, the first clamping table 24, the second clamping member 134 and the second clamping table 25 is simpler, the preparation process of each component is simplified, and the clamping operation is fast and convenient, so as to be beneficial to improving the assembly efficiency of the button 1.

In some possible implementations, the first elastic arm 131 and the second elastic arm 132 are identical in structure (the first elastic arm 131 is provided with one, two or more), and the first clip 133 and the second clip 134 are identical in structure, so that the first clip 133 and the first clip 24 are clamped in the same manner as the second clip 134 and the second clip 25.

For example, both the first clip 133 and the second clip 134 include: the second clamping piece body and the second clamping block that is located second clamping piece body top, wherein, the junction between second clamping block and the second clamping piece body is formed with spacing step (not shown in the figure).

For this implementation, the assembly process of the first clip 133 is used to illustrate the process of clipping the button 1 to the housing 2: the second clamping block of the first clamping piece 133 enters the first assembly hole 22, and the first clamping table 24 is extruded to move, so that the volume of the first assembly hole 22 is increased, and the second clamping block of the first clamping piece 133 passes through the first assembly hole 22. Because the diameter of the second clamping member body of the first clamping member 133 is smaller than the maximum diameter of the second clamping block, after the second clamping block passes through the first assembly hole 22, the second clamping member body is positioned in the first assembly hole 22 and does not press the first clamping table 24 any more, so that the first clamping table 24 is reset to move to the original position, the volume of the first assembly hole 22 is reduced, and at the moment, the bottom surface of the second clamping block is lapped on the top surface of the first clamping table 24, so that the clamping connection between the first clamping member 133 and the first clamping table 24 is realized. The process of engaging Cheng Canjian the second engaging member 134 with the second engaging platform 25 with the first engaging member 133 with the first engaging platform 24 is not repeated here.

The first side support segment 1311, the end support segment 1313, the second side support segment 1312, and the pressing sidewall 112 cooperate to form the resilient cushion chamber 1314. Wherein the first positioning portion 14 and the first clip 133 are both located on the top surface of the end support section 1313.

In this example, the end support section 1313 of the first resilient arm 131 corresponds to the "second end of the first resilient arm 131" referred to above.

By the arrangement, the two first positioning parts 14 are respectively positioned at the two ends of the end supporting section 1313, so that not only can better positioning effect be obtained, but also the assembly stability of the button 1 on the housing 2 of the electronic device is facilitated. In particular, by locating the first clamping member 133 at the middle position of the end supporting section 1313, the clamping position between the button 1 and the housing 2 of the electronic device is centered, so that the clamping of the button 1 on the housing 2 is more stable.

With respect to the push button 1 according to each of the above examples, in the embodiment of the present invention, the push button 1 is manufactured by using an integral molding process, such as an injection molding process, for the pressing portion 11, the light shielding portion 12, and the elastic portion 13.

Illustratively, two third elastic arms 135 are used, and the two third elastic arms 135 are located on opposite outer sides of the pressing side wall 112 of the push button 1, which is advantageous in simplifying the structure of the push button 1 while improving the connection effect.

In some possible implementations, as shown in fig. 9, the third elastic arm 135 includes: a second connection section 1351, a second increased elasticity section 1352, and a third connection section 1353 that are coaxially connected; the end of the second connecting section 1351, which is far away from the second bullet increasing section 1352, is integrally connected with the pressing side wall 112; the end of the third connecting section 1353, which is far from the second increased elastic section 1352, is integrally connected with the housing 2.

Based on the third elastic arm 135, the button 1 can sink when pressed and can be reset when no longer pressed.

In some possible implementations, the wall thickness of the second spring increasing section 1352 is set to be equal in thickness and 0.5mm-0.8mm, so that the button 1 is advantageously obtained through an injection molding process on the premise of ensuring that the third elastic arm 135 has sufficient elasticity, so as to ensure that no injection molding defect occurs.

In order to facilitate the operation when the button 1 and the housing 2 are integrally manufactured by an injection molding process, referring to fig. 9 and 10, a parting table is provided between the button 1 and the button via hole 21 and the third fitting hole 27, wherein the parting table is sunk by 0.8mm to 1mm with respect to the top surface of the housing 2, the bottom surface of the button 1 is sunk by 0.8mm to 1mm with respect to the bottom surface of the housing 2, and simultaneously, the sunk parting table portion is staggered from the sunk bottom surface portion of the button 1, forming a gap such that the rest is suspended except for the end portion of the third elastic arm 135 of the button 1 connected to the housing 2.
