Description

Technical Field

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

[0002] At present, intelligent LED bathroom mirrors applied to bathrooms are increasingly being popularized and applied. Because they have functions such as intelligent lighting and human body sensing, they provide more convenience for people's lives.

[0003] When people look in the mirror, usually when a person appears at the 1 / 2 - 2 / 3 height position of the mirror, the overall visual perception of appearance and so on is the best. However, the existing LED bathroom mirrors still have the following deficiencies: the height at which the LED bathroom mirror is located is fixed. For places such as public bathrooms, the heights of users using the LED bathroom mirror will be different, and the difference can even exceed one meter. As a result, the current LED bathroom mirrors can only be made very high to adapt to users of various heights. But this approach still provides a poor experience for taller or shorter users, and the too-high bathroom mirror also has the problem of being difficult to clean. Summary of the Invention

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

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] An intelligent height-adjustable LED bathroom mirror provided by the present invention includes a mirror body, a main control module, a lifting module, a first baffle, a second baffle, a camera module, and an LED module arranged on the mirror body. The camera module is arranged on the mirror body, and the LED module, the lifting module, and the camera module are all signal-connected to the main control module; the LED bathroom mirror is used to perform the following steps:

[0007] A. Obtain an image of a person in front of the mirror body through the camera module;

[0008] B. The main control module analyzes the person image to obtain the height at which the top of the person's head is located in the person image;

[0009] C. The main control module controls the lifting module to act according to the height at which the top of the person's head is located, and drives the mirror body to lift through the lifting module so that the height at which the top of the person's head is located is at the 1 / 2 - 3 / 4 position of the height of the mirror body;

[0010] Wherein, both the first baffle and the second baffle are located in front of the lifting module, and the first baffle and the second baffle are used to isolate the lifting module from the outside.

[0011] Furthermore, step C specifically includes:

[0012] C1. Obtain the relative height of the top of the person's head in the person image, denoted as H;

[0013] C2. Calculate the value of coefficient k according to the formula k = H / H';

[0014] C3 determines whether k is within the preset range k ', if so, the lifting module does not move, otherwise proceed to step C4;

[0015] C4. If k is less than the lower threshold of the preset range, the main control module drives the mirror body down through the control module; if k is greater than the upper threshold of the preset range, the main control module drives the mirror body up through the control module;

[0016] Where H' is the total height of the image.

[0017] Furthermore, step C also includes: when the lifting module drives the mirror body to lift, continuously executing steps A, B, C1, C2 and C3 until k is equal to the middle value of the value range k' and the lifting module no longer drives the mirror body to lift.

[0018] Furthermore, in step C, if the number of people analyzed in the human image is greater than 1, the following steps are performed:

[0019] Get the height of the top of each person's head in the human image;

[0020] 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;

[0021] If △H>△H', adjust the height of the mirror so that the mirror can simultaneously image the positions of maximum height and minimum height;

[0022] If △H≤△H', the height H of everyone's head is calculated, and then the main control module controls the action of the lifting module according to H, and the lifting module drives the mirror body to rise and fall so that H is located at 1 / 2-3 / 4 of the mirror body height;

[0023] The maximum height is the height of the tallest person's head, and the minimum height is the height of the shortest person's chin.

[0024] Further, it also includes two sliding grooves. The openings of the two sliding grooves face each other. The first baffle and the second baffle are respectively slidably arranged in the two sliding grooves. The sliding grooves are provided with a first limiting structure, and the first baffle and the second baffle are respectively provided with a second limiting structure. The first limiting structure and the second limiting structure cooperate to prevent the first baffle / the second baffle from disengaging from the sliding groove.

[0025] Further, the camera module includes a plurality of image acquirers, which are respectively arranged at different positions of the lens body, and are respectively used to acquire the pose images of a person at different angles in front of the lens body;

[0026] Step B specifically includes:

[0027] B1. The main control module analyzes the current pose of the person according to the human image captured by the camera module;

[0028] B2. According to the current pose of the person, analyze the pose when the person stands;

[0029] B3. According to the pose when the person stands, estimate the height where the top of the person's head is located when standing;

[0030] B4. Execute step C according to the estimation result.

[0031] Further, the LED module includes a plurality of LED drivers, each LED driver is signal-connected to the main control module, and each LED driver is respectively drivingly connected to an LED lamp bead;

[0032] Step B also includes:

[0033] Judge the expected action of the person according to the change of the person's pose;

[0034] According to the expected action of the person, control the corresponding LED driver to work to provide an illumination effect matching the expected action;

[0035] Among them, the expected actions of the person include illumination, washing, makeup, and beauty.

[0036] Further, the lens body includes a first body, a second body and a third body. The first baffle and the second baffle are respectively rotatably arranged on both sides of the first body. The second body and the third body are respectively provided with a rotation module, and the rotation module is electrically connected to the main control module. The first baffle and the second baffle are respectively installed on the top and bottom of the first body, and a plurality of image acquirers are respectively arranged on the first body, the second body and the third body;

[0037] In step B, when it is judged that the expected action of the person is makeup or beauty, the main control module drives the rotation module to act to control the second body and the third body to rotate relative to the first body respectively, and the rotation angle is 10 - 30°.

[0038] Further, the rotation module includes a lateral movement driving member, a lateral movement guide rail, and a rotation driving member. The lateral movement guide rail is installed at the back end of the first body. The second body and the third body are respectively provided with sliders, and the sliders are slidably arranged on the lateral movement guide rail;

[0039] The main control module drives the rotation module to act to control the second body and the third body to rotate relative to the first body respectively. Specifically, it includes:

[0040] Y1. The main control module controls the lateral movement driving members of the two rotation modules to act respectively to drive the second body and the third body to move away from the first body respectively;

[0041] Y2. When the second body and the third body move in place, the main control module controls the rotation driving members of the two rotation modules to act respectively to drive the second body and the third body to rotate relative to the first body respectively;

[0042] Y3. The human images obtained by the image acquisition device of the second body and the image acquisition device of the third body are respectively used to obtain the rotation amplitudes of the second body and the third body; when the rotation amplitude reaches the preset value, the rotation driving member is controlled to stop acting.

[0043] Further, in step Y3, the rotation amplitudes of the second body and the third body are adaptively adjusted according to the distance between the person and the mirror body;

Detailed implementation manner

[0051] For the convenience of understanding by those skilled in the art, the present invention will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the implementation manner does not limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0052] As Figures 1 to 4 shown, an intelligent height-adjustable LED bathroom mirror provided by the present invention includes 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 disposed on the mirror body 1. The camera module is disposed on the mirror body 1, and the LED module 6, the lifting module 2, and the camera module are all signal-connected to the main control module; the LED bathroom mirror is used to perform the following steps:

[0053] A. Obtain a human image 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 lifting module 2 to act according to the height of the human head, and drives the mirror body 1 to lift through the lifting module 2 so that the height of the human head is located at the position of 1 / 2 - 3 / 4 of the height of the mirror body 1;

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

[0057] Specifically, the present invention forms a sealed structure by the mirror body 1, the first baffle 3 and the second baffle 4, and cooperates with the wall body to separate mechanical structures such as the lifting module 2 from the outside world, thereby realizing the protection function. When the present invention works, 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 person's head according to the person image. Specifically, in the current state of the mirror body 1, the position of the person in the picture taken by the camera module. Since the camera module moves up and down synchronously with the mirror body 1, the relative height between the mirror body 1 and the person can be calculated based on this position. According to this relative height, the lifting module 2 controls the lifting of the mirror body 1, so that the person is exposed at the position of 1 / 2 - 2 / 3 in the mirror body 1. This position is the best line-of-sight position, that is, when the person is at this height, whether it is tidying up the appearance or treating the face, it is the most comfortable position, and there will be no anxiety caused by the person's height being too low or too high, thus improving the use experience.

[0058] Based on the fact that the mirror body 1 can be lifted, when the staff is cleaning, the mirror body 1 can be lowered and then wiped, which improves the convenience; while 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 person's head in the person image, denoted as H;

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

[0062] C3. Determine whether k is within the preset range k'. If so, the lifting module 2 does not act; 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 ascend via the control module;

[0064] Wherein, 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 no specific value is given in this embodiment. Since the best line-of-sight position is at 1 / 2 - 2 / 3, k' is also a range value. If k falls within this range value, it indicates that the height of the person in the image of the mirror body 1 is at the position of 1 / 2 - 2 / 3 of the total height of the mirror body 1, so the mirror body 1 does not need to be lifted. By judging the relationship between k and k', it is possible to quickly determine whether the mirror body 1 needs to be lifted, thereby improving the response efficiency of the present invention.

[0066] Preferably, step C further includes: when the lifting module 2 drives the lens body 1 to lift, steps A, B, C1, C2, and C3 are continuously executed until the lifting module 2 stops driving the lens body 1 to lift when k is equal to the middle value of the value range k'. That is, the imaging module is similar to the video recording function, and the images captured by the lens body 1 change as the lens body 1 lifts, so that the lifting of the lens body 1 is adjusted based on the real-time images 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 executed:

[0068] Obtain the heights at which all the people's heads are located in the human image;

[0069] Select the maximum height H max and the minimum height H min from all the human images, and calculate the height difference ΔH according to ΔH = H max - H min ;

[0070] If ΔH > ΔH', adjust the height of the lens body 1 so that the lens body 1 can image the positions of the maximum height and the minimum height simultaneously;

[0071] If ΔH ≤ ΔH', calculate the height value H at which all the people's heads are located, and then the main control module controls the lifting module 2 to act, and drives the lens body 1 to lift through the lifting module 2 so that H is located at the 1 / 2 - 3 / 4 position of the height of the lens body 1;

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

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

[0074] When the height difference between the father and son is 0.5 meters, for example, the father's height is 1.8 meters and the son's height is 1.3 meters, the calculated average height is 1.55 meters. That is, the mirror body 1 uses 1.55 meters as the reference height (equivalent to the height where the previous person's head was located), and then adjusts the mirror body 1 to move up and down so that the position of 1.55 meters is at the 1 / 2 - 2 / 3 position of the height of the mirror body 1, ensuring that both are imaged as much as possible at the middle part of the mirror body 1.

[0075] In this embodiment, the present invention further includes two sliding grooves 7. The openings of the two sliding grooves 7 face each other. The first baffle 3 and the second baffle 4 are respectively slidably arranged in the two sliding grooves 7. The sliding 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. The first limiting structure 8 and the second limiting structure 9 cooperate to prevent the first baffle 3 / second baffle 4 from disengaging from the sliding groove 7.

[0076] That is, two sliding grooves 7 can be equipped in the wall where the present invention is installed, specifically for the first baffle 3 and the second baffle 4 to slide. Through the sliding groove 7 and the first baffle 3 / second baffle 4 to form a mechanical seal structure, it can also protect the lifting module 2 from contacting the outside world. Since the present invention is more applied in the bathroom, this structure can effectively isolate the outside water from entering the space between the mirror body 1 and the wall, protecting the safety of the lifting module 2.

[0077] In this embodiment, the camera module includes a plurality of image acquirers 5. The plurality of image acquirers 5 are respectively arranged at different positions of the mirror body 1, and the plurality of image acquirers 5 are respectively used to acquire the 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 according to the person image captured by the camera module;

[0080] B2. Analyze the posture of the person when standing according to the current posture of the person;

[0081] B3. Calculate the height where the person's head is located when standing according to the posture of the person when standing;

[0082] B4. Execute step C according to the calculation result.

[0083] During actual use, three image acquirers 5 can be set, respectively at both ends and the middle of the mirror surface of the mirror body 1. By obtaining the images of the person at different angles, when the person is in postures such as bending down and walking, the height and posture of the person in the standing state can also be analyzed, so as to realize the adjustment of the height of the mirror body 1 when the person stands in front of the mirror body 1.

[0084] For the present application, those who are determined to use the mirror body 1 are judged based on factors such as the movement path trend and face direction of a person, so as to combine multiple dimensions and reduce the occurrence of misjudgment.

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

[0086] Step B further includes:

[0087] Judge the expected action of a person according to the posture change of the person;

[0088] According to the expected action of the person, control the corresponding LED driver 10 to work to provide an illumination effect matching the expected action;

[0089] Among them, the expected actions of a person include illumination, 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 there are more than one, the connected LED lamp beads 11 may be staggeredly arranged. For a person, different actions have different requirements for brightness. For example, only a lower brightness is required when getting up at night, being able to see the surrounding environment clearly when washing, and a larger brightness is required when applying makeup to highlight the facial details.

[0091] On this basis, the present invention calculates the action that a person is about to perform or is performing based on the posture, action, even facial expression, eye position, etc. of the person in the image at different angles, so as to be used as the expected action. After the expected action is determined, only the corresponding LED driver 10 and brightness need to be matched, so that the person can perform the expected action at the required brightness, improving the user experience.

[0092] In this embodiment, a camera is preferably used as the image acquirer 5, which can obtain more details than infrared sensors, radars, etc., and thus can quickly and accurately judge the expected action of a person by combining the deep learning of the main control module.

[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 respectively rotatably provided on both sides of the first body 12. The second body 13 and the third body 14 are respectively provided with a rotation module 15. The rotation 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. A plurality of image acquirers 5 are respectively provided on the first body 12, the second body 13, and the third body 14;

[0094] In step B, when it is determined that the expected action of the person is to apply makeup or do beauty care, the main control module drives the rotation module 15 to act to control the second body 13 and the third body 14 to rotate relative to the first body 12 respectively, and the rotation angle is 10 - 30°.

[0095] When a person needs to apply makeup or do beauty care, it is usually necessary to view the effect from multiple angles. Therefore, under this 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 as to make the details on both sides of the person visible on the second body 13 and the third body 14, enabling the user to view the effects on both sides without excessive head rotation, further improving the user experience.

[0096] In this embodiment, the rotation module 15 includes a transverse movement driving member 16, a transverse movement guide rail 17, and a rotation driving member 18. The transverse movement 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 sliders 19, and the sliders 19 are slidably arranged on the transverse movement guide rail 17;

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

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

[0099] Y2. When the second body 13 and the third body 14 reach the moving position, the main control module controls the rotation driving members 18 of the two rotation modules 15 to act respectively to drive the second body 13 and the third body 14 to rotate relative to the first body 12 respectively;

[0100] Y3. The human images obtained through the image acquisition devices 5 of the second body 13 and the third body 14 are respectively used to obtain the rotation amplitudes of the second body 13 and the third body 14; when the rotation amplitude reaches the preset value, the rotation driving member 18 is controlled to stop acting.

[0101] That is, in the non - rotating state, the second body 13 and the third body 14 are respectively in close contact with both 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 / third body 14 needs to move away from the first body 12 first to avoid extrusion and collision during rotation, ensuring safety.

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

[0103] After step Y3 , the method further 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 by 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 experiments 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 angle of rotation. This action is used to eliminate the gap between the first body 12 and the second body 13 / third body 14, and to prevent moisture 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 rotation drive member 18 can be composed of a motor and a rotating shaft, or, as in the present embodiment, a motor and a screw structure. 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 operation is as follows: 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, during which the push block slides relative to 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 move 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] As described above, it is only the preferred embodiment of the present invention, and there is no limitation to the present invention in any form. Although the present invention is disclosed above in the preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art, within the scope of the technical solution of the present invention, when making some changes or modifications using the above-disclosed technical content to equivalent embodiments of equivalent changes, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technology of the present invention shall fall within the scope of the technical solution of the present invention.
