Description

wireless sensing device

The invention relates to a wireless sensing device, in particular to a wireless sensing device capable of preventing patterns on the wireless sensing device from being worn out due to long-term use.

At present, the commonly used induction card or buckle is to seal the RFID chip inside the card or magnetic buckle. It is usually used as an access control control. When the proximity card or buckle is close to the sensing device and the reading is successful, the automatic door will be opened.

Most of the proximity cards or buckles are made of plastic injection, and most of them have no shape design, resulting in the appearance of each proximity card or buckle is the same. When you have multiple access control cards, you need to label them yourself to distinguish them.

At present, some companies provide customized proximity cards or buttons, which are engraved with text or patterns on the surface of the proximity cards or buttons, so that the proximity cards or buttons can be distinguished among many identical cards or buttons, but , the words or patterns engraved on the surface will gradually be worn away due to the prolonged use, and it will also make the surface of the induction card or induction buckle uneven.

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

According to the purpose of this creation, a wireless sensing device is provided, which has a body, the body includes a light-transmitting layer, a middle layer and a bottom layer arranged in sequence, a substrate is arranged on the surface of the bottom layer close to the middle layer, A sensing module and a light emitting module are arranged on the substrate, wherein the light-transmitting layer is close to the middle layer, or the surface of the middle layer close to the light-transmitting layer is a processed surface and a pattern part is formed.

Wherein the sensing module includes a sensing chip electrically connected to a first antenna.

Wherein the light emitting module includes a light emitting element electrically connected with a second antenna.

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

Preferably, the transparent layer is a colored transparent layer or a colorless transparent layer.

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

In order to clearly illustrate the specific implementation method, structure and achieved effects of this creation, the following examples are provided with drawings:

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

In the embodiment of the present creation, the body can be a proximity card, a proximity buckle or an Epoxy card. The body also has a perforation 10 for a lanyard or a hook or a key ring to pass through.

A pattern portion 12 is formed on a processed surface of the transparent layer 11 or the intermediate layer 21 . Please refer to FIG. 1 , in the present embodiment, the pattern portion 12 forms at least one character, number, symbol or pattern on the inner surface (as the processed surface) of the light-transmitting layer 11 near the intermediate layer 21 by laser engraving, In this way, the pattern portion 12 will not be worn away or cause the outer surface of the main body to be uneven. In other embodiments, the pattern portion 12 may be formed on the outer surface of the middle layer 21 near the transparent layer 11 (as a processed surface) by laser engraving.

To further illustrate, the transparent layer 11 can be a colored transparent layer or a colorless transparent layer. In other embodiments, fluorescent powder can also be added to the transparent layer 11 to make the main body easy to be identified at night. Alternatively, a photochromic material can be added to the light-transmitting layer 11 to make the appearance of the main body more varied.
