Detailed Description

Please refer to fig. 1 to 3. Fig. 1 is a perspective view of a switch assembly according to a first embodiment of the present invention. Fig. 2 is a perspective view of fig. 1 from another angle. Fig. 3 is an exploded view of fig. 1.

In the embodiment, the switch assembly 1 is configured to be mounted on a main circuit board 2 and control a state of an electronic device (not shown). Such an electronic device may be, for example, any suitable device. For example, the electronic device may be a speaker, and the switch element 1 may control the volume of the speaker to be increased or decreased.

The switch assembly 1 includes a housing 10, a control assembly 20, a circuit board 30, a first light emitting element 40, a second light emitting element 50, a first button 60 and a second button 70.

Please refer to fig. 2 to 5. Fig. 4 is a schematic top view of fig. 1. Fig. 5 is a schematic cross-sectional view of fig. 1.

The housing 10 includes a first housing 11 and a second housing 12. The first housing 11 includes a top plate 111 and two side plates 112. The two side plates 112 are respectively connected to two opposite sides of the top plate 111. The top plate 111 and the two side plates 112 together form an assembly slot 113. The two side plates 112 each have two fastening structures 1121, and the second housing 12 has a plurality of fastening slots 121. Two of the slots 121 are located on one side of the second housing 12, and the other two slots 121 are located on the other side of the second housing 12, so that two of the slots 121 are opposite to the other two slots 121. The second casing 12 is mounted in the assembling slot 113, and the fixing structures 1121 of the two side plates 112 are respectively bent and fixed in the slots 121 of the second casing 12. However, the number of the fastening structures 1121 of each side plate 112 is not intended to limit the present invention. In other embodiments, there may be only one retaining structure per side plate, and only one slot on each of the opposing sides of the second housing member. Alternatively, the second casing can be fixed in the assembly groove by bonding or clamping by two side plates, and the side plates can omit the clamping structure and the second casing can omit the clamping groove.

The control component 20 includes two first pins 21, 22, two second pins 23, 24 and two conductive members 25, 26. Different parts of the two first pins 21, 22 are respectively located inside and outside the second casing 12, and the two first pins 21, 22 are separated. Similarly, different portions of the two second pins 23, 24 are respectively located inside and outside the second casing 12, and the two second pins 23, 24 are separated. The two first pins 21, 22 and the two second pins 23, 24 are inserted on the main circuit board 2 and electrically connected to the main circuit board 2. The two conductive members 25 and 26 are, for example, arc-shaped conductive elastic pieces. Two conductive elements 25, 26 are located within the second housing element 12. The opposite sides of the conductive member 25 are electrically contacted with the two pads 211 of the first pin 21, and the center of the conductive member 25 is normally spaced from the pad 221 of the other first pin 22, so that the two first pins 21 and 22 are normally disconnected. Similarly, the opposite sides of the conductive member 26 are electrically contacted with the second pad 231 of the second pin 23, and the central portion of the conductive member 26 is normally kept at a distance from the pad 241 of the second pin 24, so that the second pins 23 and 24 are normally electrically disconnected.

The circuit board 30 is stacked on a surface of the top plate 111 facing away from the assembly groove 113. The top plate 111 has a plurality of snap features 1111. The two fastening structures 1111 are located at one side of the top plate 111, and the two fastening structures 1111 are located at the other side of the top plate 111, so that the two fastening structures 1111 are opposite to the other two fastening structures 1111. The circuit board 30 has a plurality of card slots 31, two card slots 31 are located on one side of the circuit board 30, and the other two card slots 31 are located on the other side of the circuit board 30, such that two card slots 31 are opposite to the other two card slots 31. The slots 31 each have a first wall 311 and a second wall 312 facing each other. In the two card slots 31 on the same side of the circuit board 30, the second wall 312 is located between the first walls 311 in an arrangement direction D1. The fastening structures 1111 are respectively bent and fastened to the slots 31, and the fastening structures 1111 respectively abut against the first wall surfaces 311 of the slots 31 and respectively keep a distance from the second wall surfaces 312 of the slots 31. Therefore, the circuit board 30 is prevented from shaking due to an unexpected external force, and the circuit board 30 is stabilized.

However, the fastening structures 1111 are not limited to abutting against the first walls 311 of the card slots 31 and keeping a distance from the second walls 312 of the card slots 31. In other embodiments, the fastening structures can respectively abut against the second wall surfaces of the slots and keep a distance from the first wall surfaces of the slots. Alternatively, the fastening structures can be respectively and simultaneously abutted against the first wall surface and the second wall surface of the clamping grooves. In addition, the number of the fastening structures 1111 and the slots 31 is not limited to the present invention. In other examples, the opposite sides of the circuit board may each have only one card slot, and the opposite sides of the top plate may each have only one card-fixing structure. Alternatively, the circuit board may be mounted on the top plate by other methods (e.g., bonding or locking), and the circuit board may omit the card slot and the top plate may omit the fastening structure.

The first light-emitting element 40 and the second light-emitting element 50 emit light of different colors, for example. The first light-emitting element 40 and the second light-emitting element 50 are disposed on the circuit board 30 and arranged along the arrangement direction D1, and the first light-emitting element 40 is closer to one side 32 of the circuit board 30 than the second light-emitting element 50. The circuit board 30 further has two first circuits 33 and two second circuits 34. The two first circuits 33 and the two second circuits 34 are embedded in the board body of the circuit board 30, for example. The two first circuits 33 each have a first connection end 331 and a first welding end 332 opposite to each other, and the two second circuits 34 each have a second connection end 341 and a second welding end 342 opposite to each other. The two first connection terminals 331 are electrically connected to the first light emitting element 40, and the two second connection terminals 341 are electrically connected to the second light emitting element 50. The two first bonding terminals 332 and the two second bonding terminals 342 are disposed on the side 32 of the circuit board 30, and the two first bonding terminals 332 are disposed between the two second bonding terminals 342. The first bonding terminals 332 of the two first circuits 33 and the second bonding terminals 342 of the two second circuits 34 are used for being bonded on the main circuit board 2, so that the first light emitting element 40 is electrically connected to the main circuit board 2 through the two first circuits 33, and the second light emitting element 50 is electrically connected to the main circuit board 2 through the two second circuits 34.

In the embodiment, the first bonding terminals 332 of the two first circuits 33 and the second bonding terminals 342 of the two second circuits 34 are located on the same side 32 of the circuit board 30, and the arrangement of the first bonding terminals 332 of the two first circuits 33 between the second bonding terminals 342 of the two second circuits 34 is favorable for circuit routing of the circuit board 30. However, the arrangement of the circuit traces of the present embodiment is not intended to limit the present invention. In other embodiments, the routing layout of the circuit can be adjusted according to actual requirements.

Part of the first button 60 and part of the second button 70 are located in the second housing member 12, and the conductive member 25 is located between the first button 60 and the second first pins 21, 22, and the conductive member 26 is located between the second button 70 and the second pins 23, 24. The first button 60 has an assembly portion 61, the second button 70 has an assembly portion 71, and the assembly portion 61 of the first button 60 and the assembly portion 71 of the second button 70 are disposed through the top plate 111 of the first housing 11 and the circuit board 30. These assembling portions 61 and 71 are arranged in the arrangement direction D1. The first light emitting element 40 is located between the two assembling portions 61 of the first button 60, and the second light emitting element 50 is located between the two assembling portions 71 of the second button 70, such that one of the assembling portions 61 and one of the assembling portions 71 are blocked between the first light emitting element 40 and the second light emitting element 50.

In this embodiment, the switch module 1 may further include two light-transmissive covers 91 and 92. The two light-transmissive covers 91 and 92 are respectively assembled to the assembling portion 61 of the first button 60 and the assembling portion 71 of the second button 70. However, the light-transmissive covers 91, 92 are optional components. In other embodiments, the switch assembly may be devoid of a light-transmissive enclosure.

In the present embodiment, the first button 60 and the second button 70 are movable relative to the first casing 11 and the second casing 12. By pressing the transparent cover 91 along the direction D2 shown in fig. 5, the first button 60 is pressed against the conductive member 25, so that the conductive member 25 is electrically contacted with the pad 221 of the first pin 22, and the two first pins 21 and 22 are electrically connected through the conductive member 25, thereby conducting the circuit controlled by the first button 60 (e.g., increasing the volume of the speaker). Similarly, by pressing the transparent cover 92 along the direction D2 shown in fig. 5, the second button 70 is pressed against the conductive member 26, so that the conductive member 26 electrically contacts the pad 241 of the second pin 24, and the second pins 23 and 24 are electrically connected through the conductive member 26, thereby turning on the circuit controlled by the second button 70 (e.g., reducing the volume of the speaker).

In the present embodiment, under the condition that the first light-emitting device 40 and the second light-emitting device 50 are arranged along the arrangement direction D1, the two-assembly portion 61 of the first button 60 and the two-assembly portion 71 of the second button 70 are arranged in the arrangement direction D1, and the arrangement of the assembly portion 61 and the assembly portion 71 between the first light-emitting device 40 and the second light-emitting device 50 is blocked, so that the light emitted by the first light-emitting device 40 and the second light-emitting device 50 can be ensured not to affect each other and not to cause the problem of color mixing even when the switch assembly 1 is in a compact configuration, thereby facilitating the user to determine the first button 60 and the second button 70.

However, the first button 60 and the second button 70 are not limited to having only one assembling portion between the first light emitting member 40 and the second light emitting member 50. In other embodiments, the assembly portion of the first button and the assembly portion of the second button may be located between the first light-emitting member and the second light-emitting member.

In the present embodiment, the width W1 of each assembling portion 61 of the first button 60 is greater than the width W3 of the first light emitting member 40, and the width W2 of each assembling portion 71 of the second button 70 is greater than the width W4 of the second light emitting member 50. Therefore, the effect of shielding the light emitted by the first light-emitting element 40 and the second light-emitting element 50 in the arrangement direction D1 can be further improved. However, the width W1 of each assembling portion 61 of the first button 60 is not limited to be greater than the width W3 of the first light-emitting member 40. In other embodiments, the first button may have only the width of the assembly portion between the first light emitting element and the second light emitting element larger than the width of the first light emitting element. Similarly, the second button may have only the width of the assembly portion between the first light emitting member and the second light emitting member greater than that of the second light emitting member. Or the width of the two assembling parts of the first button is equal to or slightly smaller than that of the first light-emitting piece, and the width of the two assembling parts of the second button is equal to or slightly smaller than that of the second light-emitting piece.

In this embodiment, the circuit for controlling the brightness of the first light emitting element 40 and the circuit controlled by the first button 60 operate independently, and the circuit for controlling the brightness of the second light emitting element 50 and the circuit controlled by the second button 70 operate independently. That is, the control of the brightness of the first light emitting element 40 is not related to the operation of the first button 60, and the control of the brightness of the second light emitting element 50 is not related to the operation of the second button 70, but the present invention is not limited thereto. In other embodiments, two first circuits can be electrically connected to two first pins respectively through the main circuit board, and two second circuits can be electrically connected to two second pins respectively through the main circuit board, so that the first button can control the brightness of the first light-emitting element, and the second button can control the brightness of the second light-emitting element.

The difference in the light colors emitted by the first light-emitting element 40 and the second light-emitting element 50 is merely an example. In other embodiments, the light emitted by the first light emitting element 40 and the light emitted by the second light emitting element 50 may be the same color.

Under the configuration that the first light-emitting member 40 and the second light-emitting member 50 emit light with the same color, the first button 60 can control the brightness of the first light-emitting member 40, and the second button 70 can control the brightness of the second light-emitting member 50, when one of the two light-emitting members is turned off and the other is in a bright state, the assembling portion 61 of the first button 60 and the assembling portion 71 of the second button 70 are blocked from being disposed between the first light-emitting member 40 and the second light-emitting member 50, so that it can be ensured that the light emitted by one of the light-emitting members does not irradiate the button corresponding to the other light-emitting member, and it can be avoided that the button corresponding to the non-light-emitting member is mistakenly recognized as an on state.

Furthermore, the conductive elements 25, 26 are optional elements. In other embodiments, the control assembly may be devoid of conductive elements. Under such a configuration, the button can be made of a conductive material, so that the two pins are electrically connected when the button is pressed to contact the two pins.

Please refer to fig. 6 and fig. 7. Fig. 6 is an exploded view of a switch assembly according to a second embodiment of the present invention. Fig. 7 is a cross-sectional schematic view of the switch assembly of fig. 6.

In the present embodiment, the circuit board 30a is located in the assembly slot 113a formed by the top plate 111a and the two side plates 112a of the first casing 11a of the housing 10a, and located between the top plate 111a of the first casing 11a and the second casing 12 a. The top plate 111a of the first casing 11a has a plurality of fastening structures 1111a, and the fastening structures 1111a of the top plate 111a are respectively bent and fastened in the plurality of fastening slots 31a of the circuit board 30 a. However, the number of the fastening structures 1111a of the top plate 111a is not limited to the present invention. In other embodiments, the top plate may have only one latching structure on each of the opposing sides, and the circuit board may have only one latching slot on each of the opposing sides. Alternatively, the circuit board can be fixed in the assembly groove by bonding or clamping by two side plates, and the top plate can omit the clamping structure and the circuit board can omit the clamping groove.

The top plate 111a further has two receding holes 1112a, and the two receding holes 1112a respectively correspond to the first light-emitting element 40a and the second light-emitting element 50a disposed on the circuit board 30a, so that light emitted from the first light-emitting element 40a and the second light-emitting element 50a can be transmitted outside.

According to the switch assembly disclosed in the above embodiment, under the condition that the first light-emitting element and the second light-emitting element are arranged along the arrangement direction, the two assembly portions of the first button and the two assembly portions of the second button are arranged in the arrangement direction, and at least two of the four assembly portions are arranged between the first light-emitting element and the second light-emitting element in a blocking manner, so that even if the switch assembly is compactly configured, the light emitted by the first light-emitting element and the light emitted by the second light-emitting element cannot affect each other, and thus, the user can judge the first button and the second button.
