Detailed Description
The following detailed description of exemplary embodiments of the utility model refers to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration exemplary embodiments in which the utility model may be practiced. Although these exemplary embodiments are described in sufficient detail to enable those skilled in the art to practice the utility model, it should be understood that other embodiments may be realized and that various changes to the utility model may be made without departing from the spirit and scope of the present invention. The following more detailed description of the embodiments of the utility model is not intended to limit the scope of the utility model, as claimed, but is presented for purposes of illustration only and not limitation to describe the features and characteristics of the utility model, to set forth the best mode of carrying out the utility model, and to sufficiently enable one skilled in the art to practice the utility model. Accordingly, the scope of the utility model is to be limited only by the following claims.
In order to solve the above problems, the following description is made with reference to the accompanying drawings:
the first embodiment is as follows:
as shown in fig. 1-2, in order to solve the problem that the signal of the object to be measured (e.g., finger) is collected by using an electronic product (e.g., mobile phone, tablet, etc.), the object to be measured is shifted, which results in inaccurate collection. The utility model provides a signal acquisition auxiliary device, which aims to improve the detection precision and comprises an acquisition part 2, wherein the acquisition part 2 completely wraps the camera part of an electronic product to prevent the camera from being scratched in the signal acquisition process. Every camera position all is equipped with the hole on the collection portion 2 to the normal use of the function of shooing of electronic product is convenient for. Just being equipped with the recess 21 that the restriction determinand removed in the testing process to main camera position on collection portion 2, when placing the determinand in recess 21 and detecting, recess 21 can restrict the determinand and remove. The bottom of the groove 21 is provided with a through hole 22 penetrating the collecting part 2. The signal of the object to be measured is captured by the camera of the electronic product through the through hole 22.
During the use, press the determinand in recess 21, use the electronic product camera to pass through-hole 22 and gather fingertip pulse signal to the finger. In this process, when the test object is pressed, the test object is guided by the groove 21 and is always confined in the groove 21. Therefore, when the signal is collected, the problem of light leakage caused by the fact that the object to be detected deviates can be avoided, and the accuracy of the signal collection is improved.
Example two:
in order to further reduce the risk of the displacement of the object to be measured in the signal acquisition process, the shape of the groove 21 is configured to be matched with the shape of the acquisition part 2 of the object to be measured. For example, in the acquisition of fingertip pulse signals, the surface 211 of the groove is an arc-shaped surface matched with the finger tip, and the radian of the arc-shaped surface is matched with the radian of the finger tip part.
The surface 211 of the groove is provided with the corrugation 212, the corrugation 212 is of a rugged structure, when an object to be detected is pressed in the groove 21, the corrugation 212 can increase the friction force between the object to be detected and the surface 211 of the groove, and the offset risk of the object to be detected in the detection process is further reduced.
Example three:
the degree of depth of recess 21 is 2.0 ~ 2.5mm, consequently when the determinand is pressed in recess 21, the determinand just fixes the best position apart from the camera, and in the testing process, this detection distance can not change for it is more accurate to detect.
Example four:
the side of the groove 21 is provided with a graphic mark for indicating the position of the main camera, a user can quickly find the position of the main camera according to the mark, and the graphic mark can be designed into various shapes and corresponds to the graphic required by a product specification. The graphic marks are engraved on the outer surface of the acquisition part 2 by using engraving technology, and the engraved graphic marks are not easy to scratch or erase in the process of using the electronic product.
Example five:
the utility model provides a mobile phone shell, wherein a shell 1 is the same as a common mobile phone shell and wraps the side and the back of the mobile phone. But different with the complete fretwork in ordinary cell-phone shell camera position, cell-phone camera position use signal acquisition auxiliary device parcel. Signal acquisition auxiliary device and cell-phone shell integrated into one piece conveniently fix signal acquisition auxiliary device on the cell-phone.
When the cardiovascular data detection APP collects the pulse signals of the fingertips of the user, the mobile phone camera and the flashlight are matched with the APP software to collect the pulse signals. The shell 1 and the collection part 2 are made of anti-skid materials, and are convenient to hold and anti-skid if silica gel or frosted materials are used. The shell 1 and the acquisition part 2 are preferably made of light-transmitting materials, so that the flash lamp can irradiate the fingertip through the shell to assist the camera in acquiring the fingertip pulse signals.
The surface 211 of recess designs for the arcwall face of laminating finger fingertip, accords with the anthropology structure, and the recess 21 of not only being convenient for fixes the finger, has also improved the comfort level of high finger simultaneously. The shape of the corrugations 212 is designed to be a fingerprint-like structure, which not only increases the friction force, but also improves the touch feeling of the arc-shaped surface.
The cambered surface that has certain degree of depth can also give the instruction of user's degree of pressure, and the user can accomplish the measurement with the finger laminating at the cambered surface to user's degree of pressure is too big, causes the inaccurate problem of measurement. The degree of depth of arcwall face is 2.0 ~ 2.5mm, consequently when the fingertip pressed in recess 21, the finger just fixed the best position apart from the camera, and in the testing process, this position can not change for detect more accurately.
The present invention and its embodiments have been described above schematically, without limitation, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching, without departing from the spirit of the utility model, the person skilled in the art shall not inventively design the similar structural modes and embodiments to the technical solution, but shall fall within the scope of the utility model.
