It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the drawings only show the components related to the present invention rather than the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
The invention provides a multifunctional suspension bracket which can flexibly rotate based on eye movement signals of a user and can realize rotation of an object to be suspended in a plane. In addition, a bracket adjusting method based on the suspension bracket is also provided.
The principle and implementation of a suspension support and a support adjustment method according to the present embodiment will be described in detail below with reference to fig. 1 to 8, so that those skilled in the art can understand the suspension support and the support adjustment method according to the present embodiment without creative efforts.
Referring to fig. 1 and fig. 2, a schematic structural connection diagram of a suspension bracket according to the present invention in an embodiment and a schematic principle diagram of the suspension bracket according to the present invention in an embodiment are respectively shown. As shown in fig. 1, the suspension bracket includes: a clamping device 1, a rotating device 2 and a circuit device 3.
The clamping device 1 is used for clamping an object to be hung; an eyeball identification device 11 is arranged on one side of the clamping device 1; the eyeball identification device 11 is used for collecting eye movement signals.
In one embodiment, the clamping device 1 includes a clamping direction motor 12 and a corresponding clamping seat.
The rotating shaft of the clamping direction motor 12 is fixedly connected with the clamping seat, and the clamping direction motor 12 is used for adjusting the direction of the clamping seat according to the direction instruction generated by the circuit device.
The rotating device 2 is connected with the clamping device 1 and is used for driving the clamping device 1 and the object to be hung to rotate.
Fig. 3 is a rear view of a suspension bracket according to an embodiment of the invention. As shown in fig. 3, in one embodiment, the rotating device 2 has a substantially triangular shape, which provides good stability. Especially when the vehicle-mounted environment vibration and impact are serious, the suspension bracket can be ensured to have certain rigidity, and deformation can be effectively resisted. The space occupied by the suspension bracket during movement is small, so that the suspension bracket is convenient to hide behind an interior rearview mirror, and the shielding of the sight of a driver during non-use and use is reduced; the suspension bracket can realize larger stroke, so that the suspension bracket can act in a larger range. The suspension bracket has the advantages of small number of parts, simple structure, good reliability and longer service life of products. The method specifically comprises the following steps: a rotary motor 21, a rotary base 22, a crank 23, a rocker 24, and a rocker 25.
One end of the rocker 24 penetrates through the rocking block 25 to be connected with the clamping device 1, the other end of the rocker 24 is movably connected with one end of the crank 23, and the other end of the crank 23 is fixedly connected with a rotating shaft of the rotating motor 21.
The rotating motor 21, the other end of the crank 23, and the rotation end of the rocker 25 are all fixed to the rotating base 22.
The rotating motor 21 rotates according to the electrical signal corresponding to the rotating instruction, and further drives the crank 23 connected with the rotating motor to deflect around the rotating shaft of the rotating motor 21, and the deflection of the crank 23 drives the rocker 24 and the clamping device 1 to swing, so that the object to be hung fixed on the clamping device 1 moves in position.
The circuit device 3 is connected with the rotating device 2 and the eyeball identification device 11 and is used for acquiring the eye movement signal, carrying out angle analysis on the eye movement signal and generating rotation angle information of a rotating motor; and sending a rotation instruction according to the rotation angle information of the rotating motor, and controlling the motion state of the object to be hung clamped by the hanging bracket through the rotation instruction.
The circuit arrangement 3 comprises a control module 31, a rotary motor drive module 32, a clamping direction motor drive module 33 and a command trigger module 34.
The control module 31 is connected to the eyeball identification device 11, and is configured to receive the eye movement signal, perform angle analysis on the eye movement signal, and generate rotation angle information of the rotating motor; and generating a rotation instruction according to the rotation angle information of the rotating motor.
The rotating electric machine driving module 32 is respectively connected to the control module 31 and the rotating electric machine 21, and is configured to receive the rotating instruction and drive the rotating electric machine 21 to rotate according to the rotating instruction.
And the clamping direction motor driving module 33 is connected with the clamping direction motor and used for driving the clamping direction motor to rotate according to the direction instruction.
The instruction triggering module 34 is configured to obtain a triggering instruction, so that the circuit apparatus 3 generates a direction instruction corresponding to the triggering instruction; the triggering instruction at least comprises one of a voice instruction, a gesture instruction and a touch instruction.
In practical application, when the object to be hung is a mobile phone in a vertical direction, a user sends a voice command of 'horizontal direction', a voice recognition circuit in the circuit device performs voice recognition, a keyword of 'horizontal direction' is extracted as a direction command, and the direction command is a command for controlling a motor to control the motor to rotate by a corresponding angle (for example, 90 degrees), so that the mobile phone becomes horizontal. The deflection motion of the suspension bracket driven by the rotating motor and the self-rotating motion of the object driven by the clamping direction motor are two mutually independent motions which can be carried out simultaneously and do not interfere with each other, so that the object to be suspended can be moved to a specified position rapidly and flexibly in multiple modes. Further, the user may issue a voice command including a specific rotation angle, for example, when the object to be hung is a mobile phone in a vertical direction, the user issues a voice command "rotate 45 degrees clockwise", and the voice recognition circuit in the circuit device performs voice recognition, and the "rotate 45 degrees clockwise" is taken as a direction command, so that the motor is controlled to rotate by a corresponding angle through the direction command "rotate 45 degrees clockwise", so that the mobile phone is changed to 45 degrees of inclination, and the user can take a picture at a specific angle.
In practical application, when the object to be hung is a mobile phone in the vertical direction, a user sends a gesture instruction, the support deflects by a preset angle according to the recognized gesture, for example, the user draws a circle clockwise by using a hand, a gesture recognition circuit in the circuit device performs gesture recognition, the mobile phone is determined to be turned from the vertical direction to the transverse direction, the transverse direction is used as the direction instruction, and the motor is controlled to rotate by a corresponding angle through the transverse direction instruction, so that the mobile phone is turned to the transverse direction.
In practical applications, the touch instruction may be a key preset on the car or the suspension bracket, or an existing key or an additional key device on a car steering wheel or a car display screen is utilized in a mode that the object to be suspended is started to rotate by itself, and the bracket is deflected by a preset angle according to the touched key, for example, the touch instruction may be a key corresponding to an up-down arrow symbol, a left-right arrow symbol, and a vertical state of the mobile phone is used as an initial state, the key of the right arrow indicates that the mobile phone needs to rotate 90 degrees clockwise, the key of the down arrow indicates that the mobile phone needs to rotate 180 degrees clockwise, and the key of the left arrow indicates that the mobile phone needs to rotate 90 degrees counterclockwise. When the object to be hung is a mobile phone in the vertical direction, a user presses a key of a right arrow on a steering wheel, a circuit device is communicated with a vehicle machine to obtain a key signal, the mobile phone is judged to rotate clockwise by 90 degrees from the vertical direction to be transverse, the transverse direction is used as the direction instruction, and the motor is controlled to rotate by a corresponding angle through the transverse direction instruction, so that the mobile phone is changed into the transverse direction.
In one embodiment, the suspension bracket is disposed on an interior mirror of an automobile and is connected to the interior mirror through the rotating device.
Please refer to fig. 4, which illustrates a front structure of a suspension bracket according to an embodiment of the present invention. In practical applications, the suspension bracket is fixed to the interior mirror, as shown in fig. 4. The holding device 1 is provided with an eyeball recognition device 11, and the deflection of the object to be hung is realized through a rotating device.
Fig. 5 is a schematic view showing a deflection process of the suspension bracket according to an embodiment of the present invention. As shown in fig. 5, taking the object to be hung as a mobile phone as an example, the initial position of the mobile phone is set to be the position when the rocker is horizontal, at this time, the mobile phone is placed behind the rearview mirror, the hanging bracket is hung at the lateral lower position of the rearview mirror in the vehicle and is in the right front of the driver, so that the space of the instrument panel is not occupied, and the operation of taking and placing the mobile phone by the driver is facilitated. Fig. 5 shows a state change process of downward deflection of the suspended mobile phone, according to the direction of a clockwise arrow in the drawing, when the gaze direction of the user is analyzed to be downward movement from the eye movement signal of the user, the distance between the user and the vertical plane where the mobile phone is located is known, so that the gaze direction of the user and the distance form a right triangle, the deflection angle of the rocker can be determined according to the calculation of the geometric relationship, and the deflection angle of the crank, that is, the rotation angle of the rotating motor, is further obtained through the conversion of the geometric relationship of each component in the rotating device, thereby realizing the downward and leftward deflection of the mobile phone. The principle of conversion from the movement angle of the user's gaze direction to the rotation angle of the motor is described with reference to the principle of fig. 8.
It should be noted that the suspension bracket of the present invention can be adjusted in size, shape and position of each component in the clamping device and the rotating device according to the installation position and the user's requirement. For example, the clamping device may be a fixing mechanism with different forms to clamp and fix different objects.
Based on the different mounting positions of the suspension bracket and the different suspended objects, the following applications can be realized in the specific embodiment:
in an embodiment of the present invention, the object to be hung is a mobile phone, and the user presents a navigation interface through the mobile phone when driving, and the user should observe the front and surrounding road conditions mainly, and it is impossible to leave the sight for too long or inconvenient to shift the sight to a too low position in the vehicle. When the user does not drive the vehicle to have a rest in the vehicle to watch the mobile phone video, the eyeballs of the user may move after keeping the same height for a long time, and therefore the mobile phone is adjusted to the position opposite to the sight line of the eyeballs of the user according to the sight line direction corresponding to the eye movement signal. Further, the suspension support receives a trigger signal before starting to start the adjustment of the motion state of the suspension support. The trigger signal may be a user's voice signal "activate the suspension bracket"; but also a gesture signal, such as a gesture of "OK"; or a key signal can be generated through a key preset on the vehicle machine or the suspension bracket, and the suspension bracket can be triggered to start according to the key signal; or the eye movement signal detected when the user looks at the suspension bracket for the first time is used as a trigger signal to start the motion control of the suspension bracket.
In another embodiment of this embodiment, since the heights, especially the upper body lengths, of the riding women are different, the cosmetic mirror clamped by the suspension bracket can be adjusted to a position where the eye sight of the user is directly opposite to the eye sight according to the sight direction corresponding to the eye movement signal based on the eye recognition, so that different women can make up by facing the cosmetic mirror at a relatively comfortable height.
In another embodiment of this embodiment, the circuit device further includes a communication device, which communicates with a communication device or a clamping handset of the vehicle to draw attention of the driver from the detected abnormal driving alarm such as overspeed through the deflection swing of the suspension bracket and the voice alarm in combination, and may further perform eye recognition on the driver through an eye recognition device on the clamping device, and determine whether the driver is distracted or distracted during driving through analysis of the eye movement signal (for example, determine that the eyes of the user do not move or continuously deviate from the driving direction within a preset time interval based on the shot user eye image), so as to draw attention of the driver from the detected abnormal driving alarm such as overspeed and distraction through the deflection swing of the suspension bracket and the voice alarm in combination, thereby helping the owner to avoid the driving risk to some extent. Further, for whether the driver is distracted during driving, sound and light alarms, instrument panels, vehicle-mounted display screens or interface popup alarms of a mobile terminal used by the driver, vibration of a vehicle seat backrest and other alarm modes which can draw the attention of the driver can be sent out based on detection signals of eyeball pictures.
In another embodiment of this embodiment, when the object to be hung is a mobile phone, the mobile phone can be automatically deflected on the hanging bracket by detecting the eye movement signal; the mobile phone can be deflected on the suspension bracket based on the combination of one or more trigger instructions in an eye movement signal, voice, gestures, preset keys and the like of a user, for example, after the suspension bracket adjusts the position of the mobile phone based on the eye movement signal, the user feels that the position is higher, a voice instruction 'downwards adjust' is sent out, a voice recognition circuit in the circuit device carries out voice recognition, a key word 'downwards' is extracted as the trigger instruction to carry out position readjustment, so that the position of the mobile phone is downwards adjusted by a small angle, and the specific small angle can be preset in advance in a computer program of the control module; the rotation of the object to be hung in the plane of the object to be hung can be achieved through the combination of one or more triggering instructions such as voice and gestures, for example, when a user watches videos in a car, when the mobile phone is clamped in the vertical direction, the user makes a gesture of drawing a circle anticlockwise by using a hand, the eyeball recognition device can shoot a picture and transmit the picture to the circuit device for recognition, or gesture sensing equipment in the circuit device performs gesture recognition, and the mobile phone is adjusted to be in a horizontal screen display mode by taking the anticlockwise turning of the mobile phone as a triggering instruction.
In another embodiment of this embodiment, various decorative articles can be hung by the hanging bracket, for example, different decorative articles such as pendant and art ornaments which do not affect driving can be clamped on the clamping device.
In another embodiment of this embodiment, the voice recognition circuit preset in the circuit device recognizes that a child is crying in the car, or the voice detection device of the mobile phone or the car recognizes that the child is crying, and transmits a crying signal of the child to the circuit device, and the circuit device enables the rotating motor and the clamping direction motor to rotate according to a preset track according to a preset toy mode in a computer program of the control module, at this time, the object to be hung of the clamping device can be a windmill, a small plush toy, and the like, so as to attract the attention of the child in the car and avoid the driver from being distracted from driving the car due to the long-term crying in the car. Furthermore, the circuit device also comprises a voice module which is used for producing animation sound effects or various sound signals capable of attracting children in cooperation with the motion of the suspension bracket; the circuit device also comprises a light module which is used for opening light in cooperation with the movement of the suspension support to further attract the attention of children, wherein the light can be changed in flickering of light with different colors and in flickering of different time lengths and in various light changes.
In another embodiment of this embodiment, the object to be hung is a curtain, and the hanging bracket is disposed above the window. The circuit device comprises a light ray detection device, when strong sunlight irradiation is detected, a judgment signal of the strong sunlight irradiation is transmitted to the control module, and the curtain is driven by automatic deflection to realize shielding at different angles and different areas so as to adjust the angle of shading in the vehicle in real time according to different driving directions of the vehicle. Specifically, when the rocker is in the vertical position, the curtain sags, and the light shielding effect is not achieved at the moment; when the rocking bar is in the horizontal position, the curtain is opened to the maximum area, and light shielding of the maximum area is carried out. In practical application, the rocker can be flexibly adjusted to any position between the vertical position and the horizontal position according to user requirements and light shielding requirements.

In one embodiment, the bracket adjusting method of the present invention is applied to the suspension bracket as shown in fig. 1 to 5. Referring to fig. 6, a schematic flow chart of a method for adjusting a stent according to an embodiment of the invention is shown. As shown in fig. 6, the method for adjusting the stent specifically includes the following steps:
s1, acquiring an eye movement signal; the eye movement signal is collected by an eyeball identification device.
In practical application, the eyeball identification device comprises an infrared light source and a camera, wherein the eyeball identification function is realized in two modes, namely, the eyeball identification function is realized through the infrared light source and the camera which are arranged on the clamping device, and the eyeball identification function is realized through the combination of the infrared light source arranged on the clamping device and the camera of the mobile phone.
When light from the infrared light source is incident on the eye and reflected light is generated on the surface of the cornea, once the eyeball of the user moves, the position where the incident light stops on the surface of the eyeball changes. The positions of the reflection light spots generated on the surface of the cornea are different, so that the eyeball motion can be analyzed by utilizing the position change of the reflection light spots. In the eyeball structure, a small foveal point, called the fovea, exists in the middle of the retina. The line connecting the fovea and the corneal center of curvature is defined as the line of sight, and the line connecting the pupil center and the corneal center of curvature is defined as the optical axis. The method comprises the steps of firstly calculating a corneal curvature center and a pupil center, then subtracting the corneal curvature center from the pupil center to calculate a sight line optical axis vector, and determining a sight line movement angle according to the sight line optical axis vector.
And S2, the eye movement signal is analyzed to generate rotation angle information used for indicating the rotation angle of the rotating motor.

and S21, determining the sight line direction of the user based on the optical axis direction quantity information of the eye movement signal.
Specifically, please refer to fig. 8, which is a schematic diagram illustrating a deflection adjustment of the bracket adjustment method according to an embodiment of the present invention. As shown in the left diagram of fig. 8, the sight direction determined by the optical axis direction amount information of the eye movement signal is presented, and when the suspension bracket is placed at a certain position, the distance s between the eyeballs of the user and the suspension bracket is known. For example, the sight line direction is inclined upwards from the horizontal, the inclined angle can be determined by the optical axial quantity information of the eye movement signal, s, d and l form three sides of a right triangle, and the distance d of the movement of the sight line direction in the vertical plane where the suspension bracket is located can be determined by knowing the included angle between l and s and the distance s.
S22, determining the intersection point of the sight line direction and the plane of the object to be hung based on the sight line direction of the user.
In the right side of fig. 8, the suspension bracket is mounted on the interior mirror as an example, the center of the interior mirror is defined as point O, the circumference represents the boundary of the swing range of the rocker of the suspension bracket, the distance d is correspondingly marked in the motion diagram of the suspension bracket, three points A, B, C form a right triangle, the point OC is the current position of the rocker of the suspension bracket, the deflection angle β of the current position is known, the length of the rocker OC is known, the included angle between OC and CD can be obtained in the right triangle OCD, and because B, C, D is located on the same horizontal line, OAC is an isosceles triangle, the included angle γ between AC and BC can be obtained by calculating α and β ABC, in the right triangle, d and the included angle γ are known, the hypotenuse AC can be obtained, and the points a and C are the intersection point of the sight line direction and the plane of the object to be suspended at different times.
S23, the rotation angle information is generated based on the change in the position of the intersection.
Specifically, the hypotenuse AC is simultaneously taken as the chord length of the circumference, and thus the chord length AC is known, and the corresponding circumferential angle α can be calculated by the chord length formula AC — 2 × OC × sin (α/2), and then the circumferential angle is the rotation angle information of the motor. It should be noted that, in practical applications, the motion structure of the crank and the rocker is simplified to illustrate the principle of the rotation angle information, and in combination with the motion principle of the crank and rocker mechanism, the rotation angle of the crank can be determined by performing relevant geometric operations, so as to determine the rotation angle information of the rotating electrical machine.
And S3, generating a rotation instruction based on the rotation angle information, wherein the rotation instruction is used for controlling the motion state of the object to be hung clamped by the hanging bracket.
Specifically, for example, the crank needs to rotate clockwise by 30 degrees to enable the object held by the suspension bracket to be in the visual direction of the user, the corresponding rotation instruction can be determined according to the specifications of different motors by using the known prior art, that is, the clockwise direction is continuously powered on until the motor rotates by 30 degrees or a plurality of pulses are continuously sent until the motor rotates by 30 degrees, the specific control mode is determined by the types of corresponding motors such as a direct current motor, an alternating current motor or a stepping motor, and finally the suspension bracket carries the fixed object to deflect clockwise by 30 degrees.
In one embodiment, the bracket adjusting method obtains a trigger instruction, and generates a direction instruction corresponding to the trigger instruction, so that the object to be hung performs plane rotation motion according to the direction instruction; the triggering instruction at least comprises one of a voice instruction, a gesture instruction and a touch instruction.

The deflection of the object to be hung can be realized according to the eye movement signal of the user, so that the object to be hung is positioned right in front of the sight line of the user at any time. The user is facilitated to view the electronic device presentation at an optimal angle and make up with a woman facing the vanity mirror at a relatively comfortable height by deflection of the item to be hung. The device can deflect in various forms through objects to be hung to attract the attention of a user when a vehicle owner drives abnormally with distraction, misoperation and the like, and helps the vehicle owner to avoid driving risks to a certain extent.
