1. Field of the Invention
The present invention relates to a twinkling lamp mechanism, and more especially to a twinkling lamp mechanism for textile products, which can glow and twinkle when vibrated.
2. Description of the Prior Art
As standard of living improves, that products only have basic functions cannot meet consumers' demands. For example, clothing not only needs to provide a function of keeping out the cold, but also needs to look well; shoes not only need to provide people's feet, but also needs to have a novel shape. Thereby besides the basic functions, the products have a higher additional value to attract attention of consumers.
Basing on the development of technology, many electric assemblies can be used to emit glowing and twinkling light, which mainly is achieved via engagements of the electric assemblies such as control ICs and so on and light emitting diodes. On the market, shoes or backpacks with vibrating and twinkling devices have the effects of attracting the attention of people due to the glow and twinkle as the wearer walks.
However, as the novelty wears off, shoes or backpacks with vibrating and twinkling devices become passe and unfashionable. Furthermore, with the development of technology, related industries are pursuing the objectives of improving the vibrating and twinkling device structure and application to allow the vibrating and twinkling devices to be used in things other than shoes or backpacks. Additionally, it is worth mentioning that most vibrating switches for the vibrating and twinkling lamps make the circuits conduct via swinging contact of springs mounted inside the shoe or backpack. If the amplitude of vibration of the vibrating switches is too small, the circuits will not conduct and produce twinkling effects.
Hence, the inventors of the present invention believe that the shortcomings described above are able to be improved and finally suggest the present invention which is of a reasonable design and is an effective improvement based on deep research and thought.
An object of the present invention is to provide a twinkling and glowing textile product which is more interesting and offers more splendid effects to meet changeable demands of consumers, and at the same time, has a sensitive glowing and twinkling effect to ensure that the desired glowing and twinkling actions occur.
To achieve the above-mentioned object, a twinkling and glowing textile product in accordance with the present invention is disclosed. The twinkling and glowing textile product includes a textile body; a decoration mounted on a surface of the textile body; and more than one twinkling lamp mechanisms combining with the decoration. Each twinkling lamp mechanism includes a glowing circuit assembly which includes a first circuit board, a control IC and a plurality of light emitting diodes, wherein the first circuit board forms circuits on and the control IC and the plurality of light emitting diodes are mounted on the first circuit board and respectively electrically connect with the circuits on the first circuit board; at least one battery electrically connecting with the glowing circuit assembly for supplying needed power; a vibrating switch assembly which includes a second circuit board, an insulating shell and at least one metal bead, wherein the second circuit board electrically connects with the circuits on the first circuit board and forms a plurality of first conducting portions and second conducting portions, the insulating shell combines with the second circuit board and has a receiving room inside, the first conducting portions and the second conducting portions are in the receiving room, and the at least one metal bead is rollably received in the receiving room; and a transparent plastic element which packages the glowing circuit assembly, the at least one battery and the vibrating switch assembly.
When the vibrating switch assembly is vibrated, the at least one metal bead contacts with one of the first conducting portions and the second conducting portions thereby a trigger signal is generated and when receiving the trigger signal, the control IC generates a driving signal to drive the light emitting diodes to twinkle within a twinkling time.

The quantity of the LEDs 23 is determined by actual demand. In the figures of this embodiment, the glowing circuit assembly 20 has six LEDs 23 for example.
Each LED 23 can be a multi-colored LED, a single colored LED, or a combination thereof. Further explaining, a multi-colored LED 23 includes a plurality of LED chips (not shown) with different colors (such as three colors including red, green and blue) and is directly mounted on the first circuit board 21 for producing lights with multi-combinations of different colors. A single colored LED 23 has a LED chips with a single color (such as yellow and so on) and is directly mounted on the first circuit board 21 for producing single color lights.
The battery 30 can be a power supply element such as Lithium Battery and so on. The battery 30 electrically connects to the other surface of the first circuit board 21 for supplying needed power. The quantity of the battery 30 is determined by actual demand. In the figures of this embodiment, the twinkling lamp mechanism 1 has one battery 30 for example.
The vibrating switch assembly 40 includes a second circuit board 41, an insulating shell 42 and at least one metal bead 43. The second circuit board 41 is smaller than the first circuit board 21 in size. A plurality of first conducting portions and second conducting portions (i.e. anodes and cathodes) are parallel and interlacedly arranged on the second circuit board 41.
The insulating shell 42 can be made of an insulation material, such as plastic, rubber and so on. The insulating shell 42 is approximately shaped like a square and can be transparent. A receiving room 421 is formed concavely inwards from a surface of the insulating shell 42. The metal bead 43 can be made of metal material with electrical conductivity such as copper and so on. The vibrating switch assembly 40 can have one or two metal beads 43. In the figures of this embodiment, the vibrating switch assembly 40 has two metal beads 43 for example.

The above vibrating unit 221 and sequence unit 222 generate a work frequency for the trigger unit 223 and the time-controlled unit 224. The trigger unit 223 electrically connects with the vibrating switch assembly 40 and generates a trigger signal for the control unit 225 when the vibrating switch assembly 40 is vibrated. The time-controlled unit 224 determines that the control IC 22 generates a driving signal and transmits the driving signal to the LEDs 23 within a twinkling time after receiving the trigger signal and cause a short circuit to disable a new trigger signal which is generated within the twinkling time, thereby to avoid delay of the twinkling time. After receiving the driving signal from the control unit 225, the driving unit 226 controls and drives each LED 20 to glow and twinkle.
Accordingly, the trigger unit 223 generates the trigger signal for the control unit 225 when the vibrating switch assembly 40 is vibrated. At this time, the LEDs 20 twinkle in turn within the twinkling time determined by the time-controlled unit 224. Additionally, because the metal beads 43 have good electrical conductivity of metal and are easy to roll, the vibrating switch assembly 40 has a sensitive electrical conductivity effect via the engagement of the metal heads 43 and the first and the second conducting portions 411, 412 of the second circuit board 41 to ensure that the desired glowing and twinkling actions occur because the amplitude of vibration is large enough.
