Description

Directional anti-lost tracker

Technical Field

The utility model relates to a directional anti-lost tracker belongs to anti-lost tracker technical field.

Background

21 of 4 months in 2021, the apple can promote a brand-new anti-lost tracker (AirTag) in 2021 spring in new product release, is different from the traditional bluetooth anti-lost tracker, has increased the accurate function of seeking in a short distance: the apple is internally provided with a UWB module in the AirTag, and the UWB module in the AirTag interacts with the UWB module in the mobile phone to realize distance measurement and obtain distance information; in order to obtain the pointing information, the apple calls a camera and a sensor of the mobile phone, and estimates coordinate points by using a local visual mileage calculation method and an IMU (inertial measurement Unit) and matching distance information obtained by UWB (ultra Wide band), thereby obtaining the pointing and realizing visual close-range searching.

With respect to conventional bluetooth anti-loss trackers, for example: hua is HaiweiTag that has released in 2022, is exactly a classic bluetooth anti-lost tracker, and its bluetooth module of carrying is mated the back with cell-phone bluetooth, can judge the distance according to bluetooth signal power to give the result of distance near/far, then utilize bee calling organ suggestion to look for. The traditional Bluetooth anti-lost tracker has obvious defects, a visual direction and distance cannot be provided for a user, the user cannot judge where the anti-lost tracker is, and the short-distance searching capability is poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a directional tracker of preventing losing, this directional tracker of preventing losing has solved among the prior art bluetooth tracker of preventing losing can't provide directional for the user, closely seeks the poor problem of ability.

In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a directional anti-lost tracker, includes at least one ultrasonic emission unit, treater and the battery of integration in the casing, treater and ultrasonic emission unit, the battery is the components and parts power supply in the anti-lost tracker.

The further improved scheme in the technical scheme is as follows:

1. in the above scheme, the shell is also provided with a Bluetooth module connected with the processor.

2. In the above scheme, the ultrasonic emission unit is a speaker or a piezoelectric ceramic piece.

3. In the above scheme, the number of the ultrasonic transmitting units is 2, and the ultrasonic transmitting units are symmetrically distributed on two sides of the shell.

4. In the above scheme, the sound emitting part of the ultrasonic emitting unit is communicated with the outside.

Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:

1. the utility model relates to a directional anti-lost tracker, two mics that all have through ultrasonic emission unit and common smart machine are mutual, obtain angle information, for the user provides anti-lost tracker's sensing, realize closely directional seeking, ultrasonic emission unit low price, with low costs, and the user need not to carry the cell-phone and removes and can accomplish the location, and is very convenient.

2. The utility model relates to a directional anti-lost tracker will prevent losing tracker's ultrasonic emission unit's vocal portion and external intercommunication, avoids ultrasonic signal to be reduced by the casing, improves the location effect.

3. The utility model relates to a directional anti-lost tracker, ultrasonic emission unit not only can regard as the positioner, still have the function of Tag middle bee calling organ on the market, integrative dual-purpose, make anti-lost tracker also can send the audible sound, and the user of being convenient for seeks the sound and distinguishes the position.

Detailed Description

Example (b): the utility model provides a pointing anti-lost tracker, refer to attached figure 1 ~ 3, including an ultrasonic emission unit 4, treater 2, bluetooth module 6 and the battery 3 of integrating in casing 1, ultrasonic emission unit 4, treater 2 and bluetooth module 6 are connected with treater 2 through the circuit respectively, here, still have components and parts such as digital analog converter between the connection of ultrasonic emission unit 4 and treater, realize that treater drive ultrasonic emission unit 4 sends ultrasonic signal's function, the circuit of realization is prior art, do not describe in detail. When the Bluetooth wireless remote control device is used, the processor 2 drives the Bluetooth module 6 to continuously send out Bluetooth broadcast signals, and intelligent equipment (mobile phone) carried by a user can scan to find an object conveniently. And the battery 3 is used for supplying power to all electric components in the ultrasonic anti-loss tracker.

The ultrasonic emission unit 4 of the anti-lost tracker sends out an ultrasonic positioning signal, and the ultrasonic positioning signal is received by two mic (self-carried without modification) of the mobile phone, so that angle calculation is realized, and therefore pointing information is obtained, and near-distance pointing guidance is realized. Wherein, the ultrasonic transmitting unit 4 is a loudspeaker/piezoelectric ceramic piece. The ultrasonic transmitting unit 4 can also emit audible sound under the driving of the processor 2 to generate a buzzing prompt effect.

Here, the number of the ultrasonic emission units 4 is selected to be 2, and the ultrasonic emission units are symmetrically distributed on two sides of the housing 1, so that not only can mutual interference be avoided, but also the spoke angles of the ultrasonic emission units 4 can be fully utilized to cover a larger range.

In order to avoid the influence of the shell 1 on the receiving and sending of the ultrasonic signals, the scheme communicates the sound-emitting part of the ultrasonic transmitting unit 4 with the outside, and has various communication options: (1) the sounding part is arranged outside; (2) a hole is formed in the shell 1, and the ultrasonic signal leaves the shell 1 from the hole; (3) an ultrasonic low attenuation material (e.g., eptfe film) is used at a position of the housing 1 corresponding to the ultrasonic transmitting unit 4.

This scheme passes through two mics interactions that ultrasonic emission unit and common smart machine all have, obtains angle information, for the user provides the directive of anti-lost tracker, realizes closely directional seeking, and ultrasonic emission unit low price, it is with low costs, and the user need not to carry the cell-phone removal and can accomplish the location, and is very convenient.

In addition, the sounding part of the ultrasonic transmitting unit of the anti-lost tracker is communicated with the outside, so that the ultrasonic signals are prevented from being reduced by the shell, and the positioning effect is improved.

In addition, the ultrasonic transmitting unit not only can be used as a positioning device, but also has the function of a Tag Chinese buzzer on the market, and has two functions as a whole, so that the anti-lost tracker can also make a sound, and a user can conveniently search the sound and identify the position.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
