Detailed Description
The present invention will be described in detail below with reference to the drawings and the specific embodiments, wherein like or similar parts are designated by the same reference numerals throughout the drawings or the description, and implementations not shown or described in the drawings are in a form well known to those of ordinary skill in the art. In addition, directional terms such as "upper", "lower", "top", "bottom", "left", "right", "front", "rear", etc. in the embodiments are merely directions with reference to the drawings, and are not intended to limit the scope of the present invention.
As shown in fig. 1 to 5, the key device of the present invention includes a projection assembly 100, a piezoelectric film 200, a controller 300, an unlocking device 400, an execution end controller 500, and a storage module, wherein the projection assembly 100 and the piezoelectric film 200 are optically matched, the unlocking device 400 is electrically connected to the controller 300, and the piezoelectric film 200 and the execution end controller 500 are electrically connected to the controller, respectively.
In this embodiment, the projection module 100 uses the HUR projection technology to project a key mark related to an authorization instruction, and uses the color-changing side window glass as a pattern forming medium. The integrated transparent piezoelectric films 200 are distributed in the window glass, the distributed positions of each piezoelectric film 200 respectively correspond to different types of key marks, and when a user touches the projected positions of the keys of the window glass, the generated pressure enables the piezoelectric films 200 to form electric signals and feed the electric signals back to the controller 300, so that the effect of pattern keys is realized. The piezoelectric film 200 in the present application is a PVDF piezoelectric film, and is disposed above the front windshield. In this application, the piezoelectric film 200 is disposed at the position of the front windshield close to the roof, which is an area that can not affect the driving vision of the driver, and is a position of the front windshield close to the driver, so that the driver does not need to divert the line of sight or only needs to divert the line of sight slightly when viewing the projection key in the projection area. When the corresponding control of the execution segment controller 500 is performed by applying pressure to the projection area, both hands of the driver can easily touch the projection area on the front windshield. The utility model provides a problem that prevents driving safety when optimizing traditional well accuse screen and use just has high technological sense and use pleasure nature, can give driver abundant driving experience.
Referring to fig. 4, the controller 300 may include a VIU (visual interface unit), a DMD (digital composite full system), a CPU (central processing unit), an in-car entertainment system, and CAN wires and radio signals electrically connecting the respective system devices, etc. The controller 300 is used for processing the authorization instructions recognized and transmitted by the piezoelectric film 200. Specifically, taking the case of the authorization instruction as the pattern unlocking (for example, the unlocking of the existing mobile phone screen), when the signal receiving unit (for example, the XBOX module) of the automobile receives the wake-up signal of the unlocking device 400, the color changing window glass controller drives the color changing film to deepen, so as to facilitate the projection assembly 100 to clearly project the key mark on the windshield. The VIU sends a pattern sending request to the car entertainment system through the CAN bus. After the car entertainment system collects the demand signal from the CAN bus, the car entertainment system transmits the picture of the preset password key pattern to the HUR controller through the LVDS interface. After receiving the picture sent by the car entertainment system, the TCON logic board performs gamma operation on the input signal through logic operation so as to improve definition and perform processing such as image beautification. The processed picture RGB data information is input into the DMD control at high speed through the Ethernet.
After receiving a series of signals of a CPU and RGB picture data input by a TCON logic board, the DMD controller converts the picture data to form signals for synchronously controlling hundreds of thousands of tiny lenses on the DMD, and transmits control signals to the DMD chip through an LVDS interface, wherein the signals can control the deflection angle of each tiny lens, and reflect a light source to form more than one million pixel patterns; meanwhile, the DMD controller also sends out a fault monitoring request to the fault monitoring IC, and inputs the brightness of the LED input by the CPU and the color information analyzed according to the picture data. After receiving a series of information input by the DMD controller, the fault monitoring IC starts to monitor the system and feeds back the fault information to the DMD controller and the CPU; and meanwhile, the color state of the RGB LED lamp set is controlled by matching the color control pins of the DMD controller with the MOSFET switch tube according to the picture color control information input by the DMD controller. The RGB LED lamp set provides current through the LED drive IC, and the fault monitoring IC is matched with the MOSFET to control the self color, and a color light source is emitted to be projected to the DMD reflecting surface. The DMD rotates the angles of hundreds of thousands of small lenses by receiving the control signal sent by the DMD controller, reflects the color light source sent by the RGB LED lamp set, forms a color image with more than one million pixels, and projects the color image on the corresponding position of the side window glass through the lens module.
The piezoelectric films 200 at different positions lead out signal wires correspondingly connected to interfaces of the domain controller, and are respectively connected with ADC sampling pins set by a CPU. When the vehicle window glass at different positions is touched, the piezoelectric film 200 at the position can send an electric signal to a unique specific pin of a CPU in the domain controller, and the CPU can set and collect the level states of different ADC pins through software to judge the password key patterns output by the piezoelectric film 200.
In the present invention, the unlocking device 400 is a starting key of an automobile, and can be connected with the controller 300 by a bluetooth connection or a mechanical connection.
The storage module stores a computer program that, when executed by the controller 300, enables the key device to perform the corresponding steps in the control method of the projected key described below.
With reference to fig. 1-5, the embodiment of the application further provides a control method of the projection key. The control method of the projection key comprises the following specific steps:
s1: transmitting an activation signal to the controller 300 based on the unlocking device 400 and waking up the projection assembly 100 and the piezoelectric film 200;
s2: projecting a pattern mark related to a control command to the area where the piezoelectric film 200 is positioned based on the projection assembly 100;
s3: based on the controller 300, the electric signal related to the control command sent by the piezoelectric film 200 is received and drives the corresponding executing end controller 500.
In step S1, an activation signal is sent to the controller 300 based on the unlocking device 400 and wakes up the projection assembly 100 and the piezoelectric film 200. The power activation of the projection assembly 100 and the piezoelectric film 200 is controlled by the unlocking device 400. In the embodiment of the application, the power supply of the automobile is started by the vehicle key to start the whole circuit power supply of the automobile. The unlocking device 400 may be a physical key or an existing bluetooth key. The starting signal can be a traditional manual starting vehicle mode or a wireless connection starting mode.
In step S2: pattern marks related to control instructions are projected to the area where the piezoelectric film 200 is located based on the projection assembly 100. After the power of the projection assembly 100 and the piezoelectric film 200 is turned on, the projection assembly 100 projects a pattern mark related to the control command to the front windshield area where the piezoelectric film 200 is located. The piezoelectric film 200 also transmits the pressing signals received from the different areas to the controller 300 in real time. The pattern mark related to the control command may be a key mark on an existing vehicle, for example, an air conditioner control pattern, a safety belt signal pattern, a tire pressure prompting pattern, etc., and the piezoelectric film 200 sends a piezoelectric signal to the controller 300 by setting a plurality of lead wires, and the controller 300 determines the source area of the piezoelectric signal, so that the driver can determine the function required for pressing. It should be noted that the glass of the region where the piezoelectric film 200 is located is a color-changing glass, and is connected to the controller 300 through the glass color-changing controller 600. The glass color change controller 600 can be darkened under the control of the controller 300 while the controller 300 receives the activation signal so that the pattern logo projected on the front windshield by the projection assembly 100 can be clearly displayed to the driver.
In step S3, the controller 300 receives the electrical signal related to the control command sent by the piezoelectric film 200 and drives the corresponding executing side controller 500. The piezoelectric film 200 can receive the pressure of the driver on different areas in real time and send the piezoelectric signals related to the control instructions of the corresponding areas to the controller 300, and the controller 300 judges the key type represented by the pressed area of the driver based on different interfaces connected with the lead wires and drives the corresponding execution end controller 500 to act. The actuator controller 500 may be a fan motor, an air conditioning power supply, a lamp power supply, etc.
