Description

wireless sensing device

The present invention relates to a wireless sensing device, particularly a wireless sensing device that can prevent the pattern on the wireless sensing device from wearing out due to long-term use.

Currently, the commonly used proximity cards or proximity buckles are made by sealing the RFID chip inside the card or magnetic buckle. They are usually used for access control. When the proximity card or proximity buckle is read successfully by the induction device, the automatic door will be opened.

Most proximity cards or buckles are made of plastic injection molding, and most of them have no design. As a result, each proximity card or buckle has the same appearance. When holding multiple access control cards, you need to label them yourself for differentiation.

At present, some operators provide customized induction cards or induction buckles, which engrave text or patterns on the surface of the induction card or induction buckle, so that the induction card or induction buckle can be distinguished among many identical cards or magnetic buckles. However, , the words or patterns engraved on the surface will gradually be worn away due to prolonged use. At the same time, the surface of the induction card or induction buckle will be uneven.

Based on the above shortcomings, the purpose of the present invention is to provide a wireless sensing device, especially a wireless sensing device that can prevent the pattern on the wireless sensing device from wearing out due to long-term use.

According to the object of the present invention, a wireless sensing device is provided, which has a body. The body includes a light-transmitting layer, an intermediate layer and a bottom layer arranged in sequence. A substrate is provided on a side surface of the bottom layer close to the middle layer. A sensing module and a light-emitting module are disposed on the substrate, wherein the light-transmitting layer is close to the intermediate layer, or a side surface of the intermediate layer close to the light-transmitting layer is a processed surface and a pattern portion is formed thereon.

The sensing module includes a sensing chip electrically connected to a first antenna.

The light-emitting module includes a light-emitting element and a second antenna electrically connected.

Preferably, the pattern part is formed by laser engraving to form at least one character, number, symbol or pattern.

Preferably, the light-transmitting layer is a colored light-transmitting layer or a colorless light-transmitting layer.

Preferably, the body also has a hole for a lanyard, a hook or a key ring to pass through.

In order to clearly illustrate the specific implementation, structure and effects of the present invention, examples are provided and described with the drawings as follows:

Please refer to Figures 1 to 3, which illustrate a wireless sensing device having a body that includes a light-transmitting layer 11, a middle layer 21 and a bottom layer 31 arranged in sequence, a sensing module and a light-emitting module. Set on a substrate 31a, the substrate 31a is located on a side surface of the bottom layer 31 close to the middle layer 21. The sensing module includes a sensing chip 33 electrically connected to a first antenna 32. The light-emitting module includes A light-emitting element 36 is electrically connected to a second antenna 35. The first antenna 32 and the second antenna 35 are used to read a reader (not shown). In the embodiment of the present invention, the sensing chip 33 and the light-emitting element 36 are electrically connected to independent antennas respectively. Therefore, when the wireless sensing device senses the antenna of the reader, the light-emitting element 36 and the sensing element can be driven simultaneously. Wafer 33. The sensing chip 33 is a RIFD chip, and the light-emitting element 36 is an LED. The intermediate layer 21 is formed by coating or potting on the surface of the bottom layer 31 to form a protective layer for the sensing module and the light-emitting module.

In the embodiment of the present invention, the body can be a proximity card, a proximity buckle or a glue card. The body also has a hole 10 for a lanyard, a hook or a key ring to pass through.

A pattern portion 12 is formed on a processed surface of the light-transmitting layer 11 or the intermediate layer 21 . Please refer to Figure 1. In this embodiment, the pattern portion 12 is formed by laser engraving on the inner surface (as the processing surface) of the light-transmitting layer 11 close to the intermediate layer 21. Thereby, the pattern portion 12 will not be worn away due to time of use or cause unevenness on the outer surface of the main body. In other embodiments, the pattern part 12 may be formed on the outer surface (as a processed surface) of the intermediate layer 21 close to the light-transmitting layer 11 by laser engraving.

To further explain, the light-transmitting layer 11 can be a colored light-transmitting layer or a colorless light-transmitting layer. In other embodiments, phosphor powder can also be added to the light-transmitting layer 11 to make the body easily identifiable at night. Alternatively, a photochromic material can be added to the light-transmitting layer 11 to make the appearance of the body more varied.
