Detailed Description
The invention will be described in further detail with reference to the following figures and specific examples, without limiting the scope of the invention.
As shown in fig. 1 to 5, the novel intelligent watch ambient light sensor according to the embodiment includes a base plate a1, a first piezoelectric patch a2 is installed above the base plate a1, three groups of light sensing elements a3 are arranged on the upper surface of the first piezoelectric patch a2, and three groups of light sensing elements a3 are arranged around the center of the piezoelectric patch; the novel side wall structure further comprises a cover, wherein the cover comprises a tubular side wall a4, the upper end of the side wall a4 extends inwards to form a circle of inward extending ring a42, and a first mounting hole is formed in the middle of the inward extending ring a 42; the lens cover a6 is further included, the lens cover a6 is installed on the first installation hole, three second installation holes corresponding to the three groups of light sensing elements a3 are formed in the first installation hole, and the second installation hole is provided with a lens a 5; a plurality of groups of decompression channels are arranged on the side wall a4, and each decompression channel comprises an inner hole a43, an outer hole a41 and an air passage a44 connected with the inner hole a43 and the outer hole a 41; the inner hole a43 is arranged on the inner wall of the upper side wall a4, the outer hole a41 is arranged on the outer wall of the side wall a4, and the inner hole a43 is higher than the outer hole a 41; the bottom of the base plate a1 is provided with a plurality of metal pin projections a 7.
The metal pin bulge a7 arranged at the bottom of the base plate a1 is used for electrically connecting the first piezoelectric patch a2, the second piezoelectric patch a8 and the corresponding light sensing element a 3; specifically, the leads of the metal pin bumps a7 are routed through the substrate board a1 to connect to respective corresponding devices.
The side wall a4 and the inner extending ring a42 are integrally formed, the height of the photosensitive element, namely the distance between the photosensitive element and the lens a5, can be adjusted simply and effectively through the piezoelectric plate, and when the focuses of the three lenses a5 are different, the focus problem when different photosensitive elements need to be matched with the corresponding lenses a5 can be effectively solved. That is, when different lenses a5 need to correspond to different focal points, at this time, because all the photosensitive elements are on one plane, the focal point of one or two photosensitive elements is ambiguous, which results in the accuracy of the light sensing of the corresponding element being reduced, therefore, when actually needed, the thickness variation of the first piezoelectric sheet a2 after being energized with different voltages can change the distance between each element and the lens a5, thereby realizing that when which element needs to be subjected to light sensing, the corresponding height is adjusted. However, even if all the lenses a5 are the same, when an error occurs at the time of packaging, the restoration of the restoration function can be performed by fine adjustment by the piezoelectric sheet.
Meanwhile, because the distance between the photosensitive element and the lens a5 is slightly changed in a shaking or swinging environment for a long time, partial distortion of optical information can be caused, and the problem of optical information distortion after the distance between the photosensitive element and the lens a5 is slightly changed due to shaking or swinging can be effectively solved by finely adjusting the photosensitive element by using the first piezoelectric sheet a 2.
According to the novel intelligent watch ambient light sensor, the bottom of the inner extension ring a42 is provided with a ring of second piezoelectric patches a 8. When the first piezoelectric patch a2 is adjusted, the second piezoelectric patch a8 can be made to follow the change, which not only adjusts the distance, but also effectively realizes the adjustment of air circulation and pressure release, in practical application, because the inside of the sensor cavity is sealed, the air pressure in the cavity increases and the temperature rises along with the conditions of light irradiation and self-heating, which are adverse factors to the lens a5 and elements in the cavity, and the inner hole a43, the outer hole a41 and the air channel a44 connected with the inner hole a43 and the outer hole a41 are arranged, which can effectively solve the problem, and when the first piezoelectric patch a2 is adjusted, the second piezoelectric patch a8 can also follow the change in continuous change to provide flowing power for the air. The air in the sensor cavity is released, so that the functions of heat dissipation and component protection are achieved. The actual access of the inner hole a43 and the actual access of the outer hole a41 are Z-shaped, so that the problem of light shielding can be effectively solved, and light pollution of a light source in an electric appliance to the light sensor is prevented.
According to the novel intelligent watch environment light sensor, the first piezoelectric patch a2 is in a regular hexagon shape, and the shape can effectively realize large thickness amplification at low voltage.
According to the novel intelligent watch ambient light sensor, the three groups of light sensing elements a3 are arranged around the center of the piezoelectric sheet at equal intervals. In the novel environment light sensor for the smart watch described in this embodiment, the lens a5 is a fresnel lens a 5.
In the present embodiment of the novel smart watch ambient light sensor, as shown in fig. 5, the number of the first piezoelectric patches a2 is three, and the first piezoelectric patches a2 correspond to three groups of light sensing elements a3 respectively. That is, the present embodiment may be formed by three quadrilateral first piezoelectric patches a2, which are respectively used to control the respective light sensing elements a3, so as to reduce the requirement of assembly precision of the elements.
The above description is only a preferred embodiment of the present invention, and therefore, all equivalent changes or modifications of the structure, characteristics and principles described in the present patent application are included in the protection scope of the present patent application.
