Electronic device

The present invention relates to an electronic device, and more particularly to an electronic device having a sonar device.

Generally, mobile electronic devices (such as robots, sweeping robots, etc.) require mobility displacement, so the ability to sense the surrounding environment to determine the correct displacement path is one of the most important functions. The mobile electronic device can sense the surrounding environment through the sensing of the sensing device, and the sensing device can actively detect the signal and receive the reflected signal to determine whether the surrounding environment has an obstacle. However, the general sensing device can only judge whether there is an obstacle in the sensing range, and cannot remove or ignore the obstacle of a specific size within the sensing range as needed.

The present invention is an electronic device comprising an electronic device body and a sonar assembly, the sonar assembly comprising a base, a sonar device and a baffle. The susceptor is disposed in the body of the electronic device, and the sonar device is disposed on the pedestal for emitting sound waves in the sensing direction, and the sound waves propagate from the sonar device in a range of the sensing region toward the tapered region. The baffle is disposed on the base and located between the sonar device and the bottom surface of the electronic device body, and extends from the base into the tapered region toward the sensing direction.

A schematic top view of the sonar device 22 of the electronic device. The electronic device of the present invention includes an electronic device body 10 and a sonar assembly 20 disposed on the electronic device body 10.

The sonar assembly 20 of the electronic device of the present embodiment includes a base 21, a sonar device 22, and a shutter 23. The susceptor 21 is disposed in the electronic device body 10 , and the sonar device 22 is disposed on the pedestal 21 . The baffle 23 is disposed on the pedestal 21 and located between the sonar device 22 and the bottom surface of the electronic device body 10 . The sonar device 22 emits an acoustic wave S in the sensing direction D1, the acoustic wave S propagates in the tapered region C, and the baffle 23 extends into the range of the conical region C of the acoustic wave S emitted by the sonar device 22. The propagation of a portion of the acoustic wave S is blocked by the baffle 23, so that the blocked partial acoustic wave S cannot generate a reflected echo, and the sonar device 22 is excluded from the sensing of a specific range. That is to say, in this embodiment, the electronic device can be ignored by the setting of the baffle 23 without changing the specifications of the sonar device of the existing electronic device without adjusting the algorithm of the obstacle avoidance detection. A specific size of obstacle within a specific range.

The electronic device body 10 of the new embodiment can be displaced on the bearing surface X. The bearing surface X of the embodiment is not limited to a horizontal plane perpendicular to the gravitational direction of the earth, as long as the surface of the electronic device body 10 that can be contacted and displaced thereon belongs to the surface, if the electronic device body 10 is in contact with the slope surface, The slope surface is also equivalent to the bearing surface X referred to in this embodiment.

In one embodiment, the sonar assembly 20 can be disposed on an outer surface of the electronic device body 10 or inside the electronic device body 10. In the embodiment in which the functions and appearance specifications of the electronic device body 10 are different, the number of the sonar components 20 on the electronic device body 10 is not limited. When the sonar component 20 senses that there is an obstacle on the route of the electronic device body 10, the electronic device body 10 can be evaded by the sensing result of the sonar component 20.

The electronic device body 10 is provided with an assembly space 11 , and the base 21 can be disposed in the assembly space 11 of the electronic device body 10 . The base 21 can be received in the assembly space 11 through a glue or a tight fit, or the base 21 can be locked and fixed in the assembly space 11 of the electronic device body 10 through a screw.

The acoustic wave S emitted by the sonar device 22 propagates from the sonar device 22 in the sensing direction D1 within the range of the tapered region C. The assembly space 11 of the electronic device body 10 has an opening 111. When the acoustic wave S of the sonar device 22 is emitted toward the sensing direction D1 and is directed toward the opening 111, the range through which the acoustic wave S passes is roughly based on the characteristics of the acoustic wave S itself. Conical on the top.

In one embodiment, the sonar device 22 is an active sonar device 22. The sonar device 22 of the present embodiment includes a circuit substrate 221, a transmitter 222, and a receiver 223. The transmitter 222 and the receiver 223 are electrically connected to the circuit board 221 , and the circuit board 221 is electrically connected to the electronic device body 10 . The sonar device 22 of the present embodiment emits the acoustic wave S by the emitter 222, and the acoustic wave S propagates in the range of the tapered region C in a direction in which the sensing direction D1 is gradually expanded. The acoustic wave S contacts the object during propagation to generate a reflected echo, and the receiver 223 receives the reflected echo to determine that there is an object in the range of the tapered region C of the sonar device 22 toward the sensing direction D1. Then, the electronic device body 10 can be evaded toward the object in the sensing direction D1 according to the sensing of the sonar device 22.

In one embodiment, the circuit substrate 221 can be attached to the base 21 through a screw lock or adhered to the base 21 by an adhesive.

In the present embodiment, since the acoustic wave S of the sonar device 22 propagates in the range of the sensing direction D1 in the tapered region C, that is, the propagation range of the acoustic wave S of the sonar device 22 is transmitted in addition to the sensing direction D1. At the same time, it also travels toward the bottom surface 12 of the electronic device body 10 and in a direction away from the bottom surface 12 of the electronic device body 10. The baffle 23 of the present embodiment extends into the tapered region C and meets the acoustic wave S propagating toward the bottom surface 12 of the electronic device body 10. Accordingly, the baffle 23 can block a portion of the acoustic wave S emitted by the sonar device 22 toward the bottom surface 12 of the electronic device body 10, and block the propagation of the partial acoustic wave S in the vertical direction D2 of the vertical bearing surface X. By blocking the propagation of a portion of the acoustic wave S in the vertical direction D2, the sonar device 22 is allowed to exclude an object that is sensed by the acoustic wave S that is blocked in the vertical direction D2. In the present embodiment, the sonar device 22 is capable of excluding objects that are sensed between the emitter 222 and the load bearing surface X. In one embodiment, the specific range of the sonar device 22 that excludes sensing may vary depending on the operating frequency of the sonar device 22, the position of the sonar device 22, or the position of the baffle 23.

The base 21 abuts against one end of the mask A, and the position of the emitter 222 and the receiver 223 of the sonar device 22 in the vertical direction D2 is located between the shutter 23 and the upper cover 24. The transmitter 222 and the receiver 223 are disposed between the baffle 23 and the upper cover 24 in the vertical direction D2, so that the operation of the transmitter 222 and the receiver 223 are not affected by the internal reflection of the internal components of the electronic device body 10. Improve the accuracy of sensing. Further, by integrating the shutter 23 with the upper cover 24 and the peripheral wall 25 as the mask A, the combination of the base 21 and the shutter 23 is made more stable and convenient, and assembly can be facilitated.

In this embodiment, the entire sonar assembly 20 can be assembled in advance and then coupled to the electronic device body 10. Accordingly, it is convenient to mount the sonar assembly 20 on different electronic device bodies 10, and also more unrestrictedly fit on the outer surface or the inside of the electronic device body 10, and have higher adaptability.

In one embodiment, the sonar assembly 20 can be fixedly disposed on the electronic device body 10 in order to meet a specific sensing requirement of the sonar device 22 at a specific operating frequency. Taking the sonar device 22 having a working frequency of 40 kHz as an example, the electronic device body 10 of the present embodiment is placed on the bearing surface X. The emitter 222 of the sonar device 22 has a central position 2221, the distance between the central position 2221 and the carrying surface X in the vertical direction D2 is 12 cm, and the distance between the central position 2221 and the baffle 23 in the vertical direction D2 is 9.8.

In this way, in the case that the electronic device body 10 does not have to evade the obstacle of a height of 15 mm (for example, the electronic device body 10 has the ability to cross the 15 mm height obstacle), the electronic device body 10 can ignore obstacles below 15 mm in height. And meet specific sensing needs. Of course, in the case where the operating frequency conditions of the sonar assembly 20 are different, the position of the sonar device 22 can also be changed to meet the demand.
