Technical Field

[0001] The invention relates to the technical field of intelligent light mirrors, in particular to an intelligent height-adjustable LED bathroom mirror. Background Art

[0002] At present, smart LED bathroom mirrors used in bathrooms are increasingly being promoted and applied, because they have functions such as intelligent lighting and human body sensing, providing more convenience for people's lives.

[0003] When people look in the mirror, they usually appear at 1 / 2-2 / 3 of the mirror's height, which is the best for the overall appearance. However, the existing LED bathroom mirrors still have the following shortcomings: the height of the LED bathroom mirror is fixed, and for places such as public bathrooms, the height of users using LED bathroom mirrors varies, and the difference can even exceed one meter. As a result, the current LED bathroom mirrors are made very high to adapt to users of various heights, but this approach still has a poor experience for taller or shorter users, and bathroom mirrors that are too high are also difficult to clean. Summary of the invention

[0004] In view of the problems of the prior art, the present invention provides an intelligent height-adjustable LED bathroom mirror, which can adjust the height according to the current height of the user, so that the user can use the mirror at the optimal height, thereby improving the user experience; and because the height of the mirror does not need to be set too high, it is easy to clean.

DETAILED DESCRIPTION

[0051] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0052] like Figures 1 to 4 As shown, the present invention provides an intelligent height-adjustable LED bathroom mirror, comprising a mirror body 1, a main control module, a lifting module 2, a first baffle 3, a second baffle 4, a camera module, and an LED module 6 arranged on the mirror body 1, the camera module is arranged on the mirror body 1, and the LED module 6, the lifting module 2, and the camera module are all connected to the main control module signal; the LED bathroom mirror is used to perform the following steps:

[0053] A. Obtaining the image of the person in front of the mirror body 1 through the camera module;

[0054] B. The main control module analyzes the human image to obtain the height of the human head in the human image;

[0055] C. The main control module controls the movement of the lifting module 2 according to the height of the top of the person's head, and drives the mirror body 1 to rise and fall through the lifting module 2 so that the height of the top of the person's head is located at 1 / 2-3 / 4 of the height of the mirror body 1;

[0056] The first baffle plate 3 and the second baffle plate 4 are both located in front of the lifting module 2 , and the first baffle plate 3 and the second baffle plate 4 are used to isolate the lifting module 2 from the outside.

[0057] Specifically, the present invention forms a sealing structure through the mirror body 1, the first baffle plate 3 and the second baffle plate 4, and cooperates with the wall to separate the mechanical structures such as the lifting module 2 from the outside world, thereby realizing the protection function. When the present invention is working, the camera module obtains the image of the person in front of the mirror body 1, and then the main control module analyzes the height of the top of the person's head based on the image of the person, specifically, the mirror body 1 is in the current state, and the person is located at the position of the picture taken by the camera module. Since the camera module rises and falls synchronously with the mirror body 1, the relative height of the mirror body 1 and the person can be calculated based on this position. The lifting module 2 controls the lifting of the mirror body 1 based on this relative height, so that the person is exposed at the position of 1 / 2-2 / 3 in the mirror body 1. This position is the best sight position, that is, at this height, the person is in the most comfortable position whether it is to tidy up the appearance or to process the face, and will not cause anxiety due to the person's height being too low or too high, thereby improving the user experience.

[0058] Since the mirror body 1 can be raised and lowered, when cleaning, the staff can lower the mirror body 1 and then wipe the mirror body 1, which improves convenience; and the first baffle 3 and the second baffle 4 usually only separate the lifting module 2 from the outside world, so they do not need to be wiped.

[0059] In this embodiment, step C specifically includes:

[0060] C1. Obtain the relative height of the top of the person's head in the person image, denoted as H;

[0061] C2. Calculate the value of coefficient k according to the formula k = H / H';

[0062] C3 determines whether k is within the preset range k ', if so, the lifting module 2 does not move, otherwise execute step C4;

[0063] C4. If k is less than the lower threshold of the preset range, the main control module drives the mirror body 1 to descend via the control module; if k is greater than the upper threshold of the preset range, the main control module drives the mirror body 1 to rise via the control module;

[0064] Where H' is the total height of the image.

[0065] The value of k is determined according to the specific position of the camera module on the mirror body 1, so the specific value is not shown in this embodiment. Since the optimal sight line position is 1 / 2-2 / 3, k' is also a range of values. If k falls within this range, it means that the image height of the person at the mirror body 1 is 1 / 2-2 / 3 of the total height of the mirror body 1, so the mirror body 1 does not need to be raised or lowered. By judging the relationship between k and k', it is possible to quickly determine whether the mirror body 1 needs to be raised or lowered, thereby improving the response efficiency of the present invention.

[0066] Preferably, step C also includes: when the lifting module 2 drives the mirror body 1 to rise and fall, steps A, B, C1, C2 and C3 are continuously executed until k is equal to the middle value of the value range k', and the lifting module 2 no longer drives the mirror body 1 to rise and fall. That is, the camera module is similar to the recording function, and the image captured by the camera body 1 will also change as the mirror body 1 rises and falls, so that the lifting and falling of the mirror body 1 is adjusted based on the real-time image to ensure the user experience.

[0067] Preferably, in step C, if the number of people analyzed in the human image is greater than 1, the following steps are performed:

[0068] Get the height of the top of all people's heads in the human image;

[0069] Select the maximum height H among all human images max and minimum height H min , and according to △H=H max -H min Calculate the height difference △H;

[0070] If △H>△H', the height of the mirror body 1 is adjusted so that the mirror body 1 can simultaneously image the positions of maximum height and minimum height;

[0071] If △H≤△H', the height value H of all people's heads is calculated, and then the main control module controls the action of the lifting module 2 according to H, and the lifting module 2 drives the mirror body 1 to rise and fall so that H is located at 1 / 2-3 / 4 of the height of the mirror body 1;

[0072] Among them, the maximum height is the height of the top of the head of the tallest person, and the minimum height is the height of the chin of the shortest person.

[0073] That is, when two people use a mirror body 1 at the same time, there is usually a difference in height between the two people. At this time, it is necessary to control according to the height difference between the two people: for example, the difference between the maximum height and the minimum height is set to 0.8 meters and the height of the mirror body 1 is 1 meter. When a father and a son use the mirror body 1 at the same time, and the father is 1.8 meters tall, the son is 0.8 meters tall, and the son's face height is 20 cm, then the imaging ratio value (for example, 0.8) is calculated according to the distance between the father and the son and the mirror body 1. The height required to simultaneously display the faces of the father and the son is (1+0.2)*0.8=0.96 meters<1 meter. Therefore, the two people can be imaged by adjusting the lifting and lowering of the mirror body 1.

[0074] If the height difference between the father and the son is 0.5 meters, for example, the father is 1.8 meters tall and the son is 1.3 meters tall, then the average height can be calculated to be 1.55 meters, that is, the mirror body 1 takes 1.55 meters as the reference height (equivalent to the height of the top of the person's head before), and the mirror body 1 is adjusted to rise and fall so that the position of 1.55 meters is located at 1 / 2-2 / 3 of the height of the mirror body 1, to ensure that both are imaged as close to the middle of the mirror body 1 as possible.

[0075] In this embodiment, the present invention also includes two slide grooves 7, the openings of the two slide grooves 7 are opposite to each other, and the first baffle 3 and the second baffle 4 are respectively slidably arranged in the two slide grooves 7; the slide groove 7 is provided with a first limiting structure 8, and the first baffle 3 and the second baffle 4 are respectively provided with a second limiting structure 9, and the first limiting structure 8 and the second limiting structure 9 cooperate to prevent the first baffle 3 / the second baffle 4 from detaching from the slide groove 7.

[0076] That is, two slide grooves 7 can be provided in the wall where the present invention is installed, which are specifically used to allow the first baffle plate 3 and the second baffle plate 4 to slide. The slide grooves 7 and the first baffle plate 3 / the second baffle plate 4 form a mechanical sealing structure, which can also protect the lifting module 2 from contact with the outside world. Since the present invention is more often used in bathrooms, this structure can effectively isolate external water from entering the space between the mirror body 1 and the wall, thereby protecting the safety of the lifting module 2.

[0077] In this embodiment, the camera module includes a plurality of image acquirers 5, which are respectively arranged at different positions of the mirror body 1, and the plurality of image acquirers 5 are respectively used to acquire posture images of a person at different angles in front of the mirror body 1;

[0078] Step B specifically includes:

[0079] B1. The main control module analyzes the current posture of the person based on the image of the person taken by the camera module;

[0080] B2. Analyze the posture of a person when standing based on his current posture;

[0081] B3. Calculate the height of the head of a person when he / she is standing based on his / her standing posture;

[0082] B4. Execute step C according to the estimated results.

[0083] In actual use, three image acquirers 5 can be set, respectively set at the two ends and the middle of the mirror surface of the mirror body 1. By obtaining images of a person at different angles, the height and posture of the person in a standing state can be analyzed when the person is bending over, walking, etc., so that the height of the mirror body 1 can be adjusted when the person stands in front of the mirror body 1.

[0084] The present application judges the person who will use the mirror body 1 based on factors such as the person's movement path trend and face direction, thereby combining multiple dimensions to reduce the occurrence of misjudgment.

[0085] In this embodiment, the LED module 6 includes a plurality of LED drivers 10, each of which is connected to the main control module by signal, and each LED driver 10 drives an LED lamp bead 11 connected thereto;

[0086] Step B also includes:

[0087] Determine a person's desired action based on changes in his or her posture;

[0088] According to the expected action of the person, the corresponding LED driver 10 is controlled to work, so as to provide a lighting effect matching the expected action;

[0089] Among them, people's expected actions include lighting, washing, makeup, and beauty.

[0090] Specifically, the number of LED lamp beads 11 connected to the LED driver 10 may be more than one, and when more than one, the connected LED lamp beads 11 may be staggered. For people, different actions have different requirements for brightness. For example, when getting up at night, only a lower brightness is needed, when washing, the surrounding environment can be seen clearly, and when putting on makeup, a higher brightness is needed to highlight the facial details.

[0091] On this basis, the present invention uses the differences in posture, action, even facial expression, eyeball position, etc. in the human image at different angles to infer the action that the person is about to or is taking as the expected action. After the expected action is determined, it only needs to match the corresponding LED driver 10 and brightness, so that the person can perform the expected action at the required brightness, thereby improving the user experience.

[0092] In this embodiment, a camera is preferably used as the image acquirer 5, which can acquire more details than infrared sensors, radars, etc., and thus can be combined with the deep learning of the main control module to quickly and with low error determine the desired action of a person.

[0093] In this embodiment, the mirror body 1 includes a first body 12, a second body 13 and a third body 14, the first baffle 3 and the second baffle 4 are rotatably arranged on both sides of the first body 12, the second body 13 and the third body 14 are respectively provided with a rotating module 15, the rotating module 15 is electrically connected to the main control module, the first baffle 3 and the second baffle 4 are respectively installed on the top and bottom of the first body 12, and a plurality of image acquirers 5 are respectively arranged on the first body 12, the second body 13 and the third body 14;

[0094] In step B, when it is determined that the person's desired action is makeup or beauty treatment, the main control module drives the rotation module 15 to control the second body 13 and the third body 14 to rotate relative to the first body 12, respectively, with a rotation angle of 10-30°.

[0095] When people need to put on makeup or do beauty treatments, they usually need to view the effects from multiple angles. Therefore, under the expected action, the second body 13 and the third body 14 of the present invention will rotate slightly relative to the first body 12, so that the second body 13 and the third body 14 can see the details on both sides of the person, allowing the user to view the effects on both sides without turning the head too much, further improving the user experience.

[0096] In this embodiment, the rotating module 15 includes a transverse driving member 16, a transverse guide rail 17 and a rotating driving member 18. The transverse guide rail 17 is installed at the back end of the first body 12. The second body 13 and the third body 14 are respectively provided with a slider 19, and the slider 19 is slidably arranged on the transverse guide rail 17.

[0097] The main control module drives the rotation module 15 to control the second body 13 and the third body 14 to rotate relative to the first body 12, specifically including:

[0098] Y1. The main control module controls the lateral movement driving member 16 of the two rotating modules 15 to drive the second body 13 and the third body 14 to move away from the first body 12;

[0099] Y2. The second body 13 and the third body 14 are moved into position, and the main control module controls the rotation drive member 18 of the two rotating modules 15 to respectively move to drive the second body 13 and the third body 14 to rotate relative to the first body 12;

[0100] Y3. The image of the person acquired by the image acquirer 5 of the second body 13 and the image acquirer 5 of the third body 14 changes respectively to obtain the rotation amplitude of the second body 13 and the third body 14; when the rotation amplitude reaches the preset value, the rotation drive member 18 is controlled to stop the action.

[0101] That is, in the non-rotating state, the second body 13 and the third body 14 are respectively in close contact with the two sides of the first body 12, so that there is no gap between the second body 13 and the first body 12, and between the third body 14 and the first body 12. Therefore, before the second body 13 and the third body 14 rotate, the second body 13 / the third body 14 needs to be away from the first body 12 to avoid squeezing and collision during rotation, thereby ensuring safety.

[0102] In this embodiment, in step Y3, the rotation amplitude of the second body 13 and the third body 14 is adaptively adjusted according to the distance between the person and the mirror body 1;

[0103] Step Y3 also includes: controlling the second body 13 and the third body 14 to move toward the first body 12 through the transverse driving members 16 of the two rotating modules 15, and the movement amount is adaptively adjusted according to the rotation amplitude of the second body 13 and the third body 14.

[0104] That is, the rotation amplitude of the second body 13 and the third body 14 is determined according to factors such as the distance between the person and the mirror body 1 and the person's desired action. The specific data can be obtained through routine tests and will not be repeated here. After the second body 13 and the third body 14 have completed their rotation, they will move a certain distance toward the first body 12 according to the rotation angle. This action is used to eliminate the gap between the first body 12 and the second body 13 / third body 14, and to avoid water vapor from entering the space between the mirror body 1 and the wall as much as possible.

[0105] It should be noted that since the second body 13 and the third body 14 need to rotate, the first baffle 3 and the second baffle 4 only need to be connected to the first body 12, and the length of the first baffle 3 and the length of the second baffle 4 are not less than the sum of the lengths of the first body 12, the second body 13, and the third body 14. Preferably, the length of the first baffle 3 and the length of the second baffle 4 are equal to the sum of the length of the first body 12, the length of the second body 13, the length of the third body 14, the moving stroke of the second body 13, and the moving stroke of the third body 14.

[0106] Specifically, the rotating drive member 18 can be composed of a motor and a rotating shaft, or it can be composed of a motor and a screw structure as in the present embodiment, the end of the screw structure is rotatably connected to a push block, and the back ends of the second body 13 and the third body 14 are respectively provided with a slide groove for accommodating the push block. The specific action is: when rotation is required, the transverse driving member 16 first controls the second body 13 / third body 14 to move away from the first body 12, and during this process, the push block slides relatively along the slide groove; when the transverse movement is completed, the motor is actuated to drive the screw structure to rotate, thereby controlling the push block to push forward in the slide groove, and the second body 13 / third body 14 moves away from one end of the first body 12. Since the second body 13 / third body 14 is rotatably arranged on the transverse driving member 16, the seesaw is used to control the second body 13 / third body 14 to rotate relative to the first body 12.

[0107] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention is disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent changes and modifications made to the above embodiments according to the technology of the present invention are all within the scope of the technical solution of the present invention without departing from the content of the technical solution of the present invention.
