Description

Vision correction glasses based on dynamic refraction adjustment

Technical Field

The utility model relates to the technical field of vision recovery auxiliary devices, in particular to vision correction glasses based on dynamic refraction adjustment.

Background

The vision correction glasses based on dynamic refraction adjustment refer to glasses capable of dynamically adjusting the diopter of the glasses lenses, and are worn for the purpose of exercising vision, and the diopter of the glasses lenses is dynamically adjusted so that the glasses of a user can be exercised, thereby being beneficial to vision recovery.

The structure of the intelligent glasses is as per the Chinese utility model of 202222143903.8, and the lens adjusting mechanism 2 is used for moving the front lens 3 left and right or the rear lens 4 left and right and changing the area where the front lens 3 and the rear lens 4 overlap. Wherein, at least the thickness of the front lens 3 or at least the rear lens 4 is changed, when a user wears the intelligent glasses for improving vision and performs vision through the overlapping area of the lens vision, the overlapping area of the front lens 3 and the rear lens 4 is changed, so that the eyes of the user need to adapt to different diopters, and the functions of diopter adjustment and adaptability rehabilitation are achieved. "

Such vision correcting glasses are mainly powered by a rechargeable battery configured by the vision correcting glasses themselves, or are directly plugged into a socket through a plug to power the power consumption components, so that after the use, when a user forgets to actively press a close button, the vision correcting glasses usually do not know when to automatically close the system or power off.

The common solutions are: the training program is recorded in advance in the singlechip of the vision correction glasses, and the vision correction glasses are automatically controlled to be closed after the time of reaching the training program, and can be also understood as being closed at regular time.

However, this vision correction glasses have a disadvantage that the normal training time is about 15 minutes, and if the user stops the use of the glasses in the middle, the user should wait for the training time (15 minutes is an example) to finish and then close the glasses by self-control, and if the user does not use the glasses again on the day after 3 minutes of use, i.e., because the user leaves the glasses due to sudden matters, the user should keep the power-on operation for 12 minutes to close the glasses by self-control. For the mode of directly plugging the plug with the socket to supply power for the power utilization element, the reduction of the electric energy consumption is not facilitated; for the mode of adopting the rechargeable storage battery to supply power for the power utilization element, not only the reduction of the power consumption is not facilitated, but also the electric quantity of the storage battery is possibly caused to be at a low value (the power is continuously supplied for 12 minutes after the user leaves) under the condition that the user is unknowing, so that the next use is not facilitated.

The motor lead screw assembly can realize stepless movement, so that the movement of the front lens or the rear lens is more accurate, namely, the diopter change amount can be more accurate.

It is noted that either the front or rear lens may have a variation in thickness as taught in patent No. 202222143903.8 to provide different diopters as the overlapping areas of the fields of view of the front and rear lenses vary.

In the embodiment of the utility model, the vision correction glasses based on dynamic refraction adjustment further comprise a human body sensing unit, wherein the human body sensing unit comprises a human body sensing circuit and a sensor 6 arranged on the glasses frame 1, the sensor 6 is connected with the signal input end of the controller 2 through the human body sensing circuit, and the controller 2 performs power-off control according to human body leaving signals provided by the sensor 6 and the human body sensing circuit.

When the vision correction glasses are used, after a user takes off the glasses, the human body sensing unit senses that the user is far away from the sensor 6, and correspondingly provides a human body leaving signal for indicating that the user stops using to the controller 2, so that the controller 2 can timely know whether the user takes off the glasses or not, and accordingly control is performed, namely the power-off control is performed, and the vision correction glasses are not in a power-consuming state any more.

In the embodiment of the present utility model, the human body sensing unit further includes a delay circuit 7, and the delay circuit 7 allows the controller 2 to obtain the human body leaving signal provided by the sensor 6 through the human body sensing circuit after the sensor 6 continuously detects that the human body leaves to reach the threshold time. The delay circuit 7 allows the present vision correction glasses to remain currently powered on for a certain period of time, denoted as a delayed power-off time, when the glasses are taken off (the human body is far from the sensing area of the sensor), and the controller 2 is only enabled to perform power-off control when the time for taking off the glasses (the human body is far from the sensing area of the sensor) reaches the delayed power-off time.

The delay control time is preferably more than 10s, such as more reasonably 20s, to avoid false power failure caused by temporary removal of the glasses and brief rest, or to avoid false power failure caused by careless detachment of the glasses.

Further, the sensor 6 may be a pyroelectric infrared sensor mounted on the frame 1, and the sensor 6 is directed toward the head of the user when the user wears the frame. Human body approaching and human body far away feeling identification is carried out in an infrared sensing mode.

The delay circuit comprises a resistive load R10 and a capacitive load C6, and the adjusting end RR1 of the processing chip U1 is connected in series to the ground end through the resistive load R10 and the capacitive load C6. The SW1 is connected with a high level, so that the circuit is in a working mode capable of being triggered repeatedly, and the controller is enabled to receive a human body leaving signal for indicating that the user stops using when the sensor senses that the user leaves and reaches the time of delayed power-off.

Under the condition that other values are unchanged, the resistance value corresponding to the resistive load R10 and the capacitance value corresponding to the capacitive load C6 directly influence the delayed power-off time, namely, during production, the resistive load R10 and the capacitive load C6 with different values are adopted, so that different delayed power-off times can be obtained, and production can be selected according to use requirements.
