Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The embodiment of the utility model discloses wireless charging coil device, it is shown to refer to fig. 1, including coil 1, protective housing 2 and a plurality of first sensor S1, wherein:

coil 1 is located protective housing 2 inside, and protective housing 2 inner wall is equipped with the unanimous constant head tank 21 of level, and the induction range of a plurality of first sensors S1 is towards the protective housing 2 outside, and sets up on protective housing 2 inner wall through the constant head tank 21 interval.

Specifically, the positioning groove 21 on the inner wall of the protective shell 2 reserves a vacant position for placing the first sensor S1 for the protective shell 2 in the design and production process, and may be a plurality of positioning grooves 21 corresponding to the first sensors S1 one to one, the first sensor S1 can only be installed at discrete determined position points of the positioning groove 21, the positioning groove 21 may also be one or a plurality of strip-shaped grooves with unchanged horizontal height, and the first sensor S1 can slide in the strip-shaped grooves to adjust the position.

Specifically, the first sensor S1 is specifically a radar sensor. It can be understood that, in the present embodiment, the first sensor S1 has the ability of detecting the external environment through the protective casing 2, and therefore, can be disposed inside the protective casing 2, and is cheaper and more reliable when the wireless charging coil device is transported and installed as a whole.

Further, in addition to the physical position and sensing direction of the first sensor S1, an angle adjustment member 22 may be provided to assist the first sensor S1 to work in a sensing direction of a specific angle, and in particular, as shown in fig. 2, each first sensor S1 is fixed on the positioning slot 21 by the corresponding angle adjustment member 22.

It is understood that when the coil is applied in different environments, the state of the angle adjustment member 22 of the first sensor S1 is also different. As shown in fig. 3a, when the coil 1 is a transmitting coil, the transmitting coil is usually installed under the ground, the sensing direction of the first sensor S1 is an elevation angle such that it can be detected upwards to the ground, and each first sensor S1 can be fixed on the positioning slot 21 by the corresponding angle adjusting member 22 with a sensing direction of 30 ° elevation angle or other angles; similarly, as shown in fig. 3b, when the coil 1 is a receiver coil of the car bottom, and the sensing direction of the first sensor S1 is obliquely downward, each first sensor S1 can be fixed to the positioning groove 21 by the corresponding angle adjustment member 22 with a sensing direction of a depression angle of 30 ° or other angles, thereby ensuring that the ground area within a predetermined distance downward and outward from the receiver coil can be detected. The angle adjustment member 22 may be a fixed angle, and a different angle adjustment member 22 may be replaced each time the angle is adjusted, and the angle adjustment member 22 may also be a member including a rotating shaft and an adjustable angle, so that the installation angle of the first sensor S1 can be flexibly adjusted according to the requirement by one angle adjustment member 22. It is understood that the installation angle of the first sensor S1 on the angle adjustment member 22 and the pitch angle of the first sensor S1 have close correlation with the actual coil working environment, and may be set according to the detection requirement.

It will be appreciated that in order to ensure coil periphery detection is not missed, the sensing ranges of adjacent first sensors S1 have overlapping regions. Referring to fig. 4, the first sensors S1 are spaced apart from each other on the inner wall of the protective case 2, and their sensing ranges are indicated by hatching, i.e., four sides, four corners, and outwardly extending portions of the coil 1.

Further, the wireless charging coil 1 apparatus may further include a plurality of second sensors;

the body of each second sensor is located inside the protective case 2;

the antenna probe of each second sensor is externally detected through the through hole 23 of the protective case 2.

It will be appreciated that here the second sensor, whose antenna probe must be located in the external detection environment, is different from the first sensor S1, which is able to operate through the protective case 2. Based on the modular demand that integrates, arrange the main part of second sensor inside protective housing 2, the main part position does not do specifically limit to set up through-hole 23 on protective housing 2 with the antenna probe of second sensor, make antenna probe can stretch out protective housing 2 and externally detect. Such a second sensor required by the antenna probe includes a pyroelectric infrared sensor or the like.

Further, as shown in fig. 5, the sensing directions of the antenna probes of the second sensors are consistent with the sensing directions of the corresponding first sensors S1, so that the detection ranges of the first sensors S1 and the second sensors are consistent, and accurate and reliable bases are provided for subsequent detection result analysis.

It can be understood that the whole wireless charging coil device comprises a wireless charging system, a monitoring system and a protective case, wherein the wireless charging system mainly comprises the coil 1, and the monitoring system comprises the first sensor S1, the second sensor and a controller connecting all the first sensors S1 and all the second sensors. The controller analyzes the detection results of all sensors, including the first sensor S1 and the second sensor, and takes measures such as uploading information, turning on a living thing driving-off device, analyzing living thing orientation, sending information to a wireless charging system, etc., when biological information or living thing information is detected.

Specifically, the work flow of the whole wireless charging coil device mainly comprises the following contents:

when the wireless charging is started, the monitoring system starts to be electrified for self-checking; the self-checking is to detect each sensor after being electrified, and the sensors can send signals to the controller after being electrified normally to represent that the functions are normal, and then the sensors are automatically recovered to start the real-time monitoring of the functions.

And after the self-checking is normal, all the sensors are started to monitor the information in the sensing range. When the sensor detects detection information with certain intensity, the detection information is sent to the controller, the controller analyzes whether living object information appears according to the detection information, determines the direction of the living object according to the living object information, starts the driving-away device and can also send living body alarm information to the wireless charging system; after the wireless charging system receives the living object warning information, the charging power can be reduced or stopped.

And when the sensor does not detect the living information within the preset time period, the sensor automatically recovers the monitoring state and does not report the alarm information any more. At the moment, the alarm of the monitoring system is eliminated, the driving-off device can be stopped, and the charging state of the wireless charging system is recovered.

In the wireless charging coil device in the embodiment, the sensitivity of the sensor can be adjusted, and the sensing judgment precision and distance can be adjusted. The high precision can realize the induction judgment of a small object and a long distance, but also can reduce the anti-interference performance of the system. And the real-time monitoring of the moving water ball, the small animal, the human body and the like in the detection range can be realized by adjusting the appropriate sensitivity. After the living body information is detected, the living body information can be matched with a proper driving device, such as a loudspeaker, a high-frequency flash, a blowing system and the like, so as to drive away the living body.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
