The following description is given to enable any technician in the field to implement and use the present invention. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present invention can be implemented without using these specific details.

Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present invention.

[0055] An embodiment of the present invention provides an input system for a new energy vehicle, and the input system for the new energy vehicle includes a non-touch input module, a touch input module, and a central processing module, which are described in detail below.

[0056] See also Figure 1 , Figure 1It is a schematic diagram of the principle of an embodiment of an input system for a new energy vehicle provided by an embodiment of the present invention.

[0057] The input system of new energy vehicles includes a non-touch input module, a touch input module and a central processing module, among which:

[0058] like Figure 2 As shown, the non-touch input module includes a light projection module, an image sensor, a detection light module (detection light), a micro-vibration module and a battery. The light projection module, the image sensor, the detection light module and the micro-vibration module are respectively connected to the central processing module, and the micro-vibration module is a module that can be worn by the user;

[0059] The contact input module includes an imaging device and an imaging pen. The imaging device is connected to the central processor, and the imaging device receives a signal generated by the contact of the imaging pen.

[0060] The central processing module is connected to the display module of the new energy vehicle.

[0061] like Figure 3 As shown, the light projection module includes an excitation light source, a transparent paper film group, a convex lens and a diffraction light imaging module, wherein;

[0062] The excitation light source is used to emit point light when enabled by laser driving;

[0063] The input device image is printed on the transparent paper film in the transparent paper film group, and the point light passes through the transparent paper film to obtain the input device image light information;

[0064] The convex lens and the diffraction light imaging module are used to generate a two-dimensional input pattern according to the projection of the image light information of the input device.

[0065] In some embodiments, the light source projection module performs projection of an input device (eg, a keyboard, a telephone dial, etc.) onto a user input surface.

[0066] In some embodiments, different transparent paper films in the transparent paper film set are printed with different input device images;

[0067] The transparent paper film group includes a rotating shaft ring and a motor, and the central processing module can control the motor to drive the rotating shaft ring to switch the input device image.

[0068] Specifically, the light source projection module is placed at the top of the entire system, wherein the excitation light source emits a point light under the laser drive enable, and obtains the input device image light information after passing through the transparent paper film printed with the input device image. The style of the input device can be preset on the rotating shaft ring in the transparent paper film group, and the central processing module enables the rotation of the motor to switch the corresponding input device image information film.

[0069] The input device image light information is projected onto the user input end surface (such as a flat desktop, wall or ground, etc.) through a convex lens and traditional diffraction light imaging technology to obtain a two-dimensional image of the corresponding input pattern.

[0070] Excitation light source:

[0071] In order to change the inert gas in the bulb of the excitation light source from the normal state to the ionized state, a large excitation power is required. Once started, this excessive power becomes redundant. This excess power will have a significant negative impact on the stable operation of the entire circuit. First, due to the large excitation power, the power consumed by the excitation tube T will also be large, which can easily cause the tube to overheat, thereby reducing the stability of the entire circuit. Second, since a considerable portion of the excess power is released as radiation, it will cause interference to the system and cause electromagnetic compatibility problems.

[0072] In the bias of the excitation circuit, a positive coefficient PTC resistor Rp is connected in parallel, and its temperature characteristics are as follows Figure 4 As shown:

[0073] And Rp is placed closer to the light source to sense the ambient temperature. The actual excitation circuit is as follows Figure 5 As shown:

[0074] Figure 5 In the process, the self-oscillation is completed according to the traditional analog circuit principle. At the beginning, the light source does not emit light, and the temperature zone where Rp is located is relatively low. At this time, the light source is in accordance with Figure 5 Stimulated radiation is performed, thereby emitting light. When the light is emitted to a certain extent, the light is converted into heat, and the light source will radiate heat energy to the outside, thereby significantly increasing the ambient temperature of the temperature zone where Rp is located. When it reaches a certain threshold (for example, 110 degrees Celsius), due to the characteristics of Rp resistance, its resistance value will rise. At room temperature, the resistance value of Rp is about 20 ohms. When the excitation light source enters the constant temperature point of about 110 degrees, its resistance value will quickly rise to tens of kiloohms. This allows the excitation light source to obtain a relatively ideal corresponding excitation power during the ignition stage and the normal working stage.

[0075] The excitation light source is at room temperature, Rp is very small, and the base current of the oscillating excitation tube T is very large, so the excitation current Ic of the tube T is very large, and the excitation light source can obtain a very high excitation power, thereby quickly starting the excitation light source. As the temperature of the constant temperature zone of the real excitation light source continues to rise, Rp rises, the base current of the excitation tube T decreases rapidly, and the excitation current Ic also decreases rapidly until the constant temperature point of about 120 degrees. Compared with the traditional method, this patent has the following effects:

[0076] During the startup phase of the excitation light source, Rp is very small, Ib is very large, Ic is very large, and the excitation power is very large, so the excitation light source starts working quickly.

[0077] After the excitation light source reaches the constant temperature point, Rp is very large, Ib is very small, and Ic is very small. The excitation power to maintain the normal operation of the spectrum lamp is very small, which reduces power consumption.

[0078] Since Rp is a positive temperature coefficient, as the temperature rises, Rp rises, Ib decreases, and Ic decreases. The Ic of a general transistor T is a positive temperature coefficient, and as the temperature rises, Ic increases. The Ic changes caused by the temperature effect of the two can compensate each other. Therefore, this method can play a good role in temperature compensation, ensuring that the Ic current of the excitation tube T does not change with the change of the external environment temperature, thereby ensuring the stability of the light output of the excitation light source.

[0079] The structure of the excitation light source:

[0080] The structure of the entire excitation light source Figure 6 The excitation light source is an equal hexagonal structure, the upper plane of the equal hexagonal structure is the printed board cover, the lower plane is the printed board bottom, the surrounding is the printed board surface, the interior of the equal hexagon is provided with a light-emitting module, and the printed board cover is provided with a light-transmitting hole.

[0081] In some embodiments, the inner sides of the relatively equal hexagonal structures of the printed board cover and the printed board bottom are covered with metal copper.

[0082] Specifically, it is composed of an equal hexagonal structure, with the upper plane being the printed board cover, the lower plane being the printed board bottom, four printed board surfaces around it, and the interior being composed of a light-emitting module. The printed board cover and the printed board bottom are all covered with metal copper on the inner side of the hexahedron to eliminate the electromagnetic interference of the light-emitting module on the upper and lower sides; the printed board cover and the printed board bottom are all placed with functional parts on the outer side of the hexahedron (see below for details); the four printed boards are all covered with metal copper on the inner side of the hexahedron to eliminate the electromagnetic interference of the light-emitting module on the left, right, front, and back sides; the light-emitting module is equipped with a light source and an inductor coil for stimulating the light source to emit light, and the entire device is fixed on the bottom surface of the printed board.

[0083] Light emitting module:

[0084] The entire light module is Figure 8 As shown, the light-emitting module includes a light-emitting bulb, a light-shielding tube, an inner inductor coil and an outer inductor coil, wherein: the light-emitting bulb is arranged inside the light-shielding tube and partially exposes the edge of the light-shielding tube; the light-shielding tube is fixed to the bottom of the printed board, and the outer wall is wound with an inner inductor coil and an outer inductor coil to generate high-frequency excitation.

[0085] Specific address, such as Figure 7As shown, the light shielding tube is made of PVC material plate into a cylindrical tube shape and fixed on the bottom of the printed circuit board by fixing threads (see below for details). The light-emitting bulb is placed inside the light shielding tube and closely contacts the wall of the light shielding tube, and the light-emitting bulb part is exposed from the edge of the light shielding tube to generate light radiation to the outside under stimulation. The outer wall of the light shielding tube is wound with inner and outer double-layer inductance coils to generate high-frequency excitation.

[0086] The inductor coil is wrapped with enameled wire and wound in double layers. Figure 8 As shown:

[0087] When current passes through the inductor coil, due to the double-layer dense winding method, it can be considered that the electromagnetic generation will be 0, which can greatly reduce the impact of electromagnetic radiation.

[0088] Printed board bottom:

[0089] The structure of the printed circuit board bottom is as follows Fig. 9 As shown, the entire board is made of PCB material and is fixedly connected to the four-sided printed circuit board in the previous figure. Fig. 9 As shown, the inner surface is a copper-clad metal layer. There is a fixed threaded plug-in on it to fix the light-emitting module; a thermal sensor is placed on the left side, and its material is a commonly used thermistor, which is used to measure the temperature zone at the bottom of the printed circuit board; a light sensor is placed on the left and right sides of the bottom of the printed circuit board to detect the light leakage of the light-emitting module in the bottom area of ​​the printed circuit board.

[0090] The entire printed circuit board bottom is a sealed parallelogram plane structure.

[0091] Printed circuit board cover:

[0092] The structure of the printed board cover is as follows Fig.10 As shown, the entire board is made of PCB material and is fixedly connected to the four-sided printed circuit board in the previous figure. Fig.10 As shown, the inner surface is a copper-clad metal layer. A temperature control resistor is placed on the left side, and its material is a PTC resistor (i.e., Rp in the front excitation circuit diagram), which is used in conjunction with related circuits to stabilize the excitation luminous power of the light-emitting module; a photocell is placed on the left and right sides of the bottom of the printed circuit board to detect the intensity of the light radiated by the light-emitting module. There is an outlet at the center of the entire board to introduce the enameled induction wire into the coil link of the light-emitting module.

[0093] It is worth noting that the printed circuit board cover is not a sealed plane structure, because the light emitted by the light source must be able to pass through the lens in the entire optical path device, so it is designed according to Fig.11 The structure shown is laid out.

[0094] Detection optical module:

[0095] The structure of the detection optical module is as follows Fig.12 As shown, the detection light module is located at the bottom of the entire device, and mainly completes the light projection of the user input surface.

[0096] Its working principle is the same as that of the above-mentioned light source projection module. It only projects an excitation light beam, and no specific image is displayed on the user input surface. To the user, it is an invisible plane.

[0097] In some implementations, such as Fig.13 As shown, Figure 3 A schematic diagram of the projection plane and the user input plane.

[0098] Plane 1 is a non-image graphic layer generated by the detection light module.

[0099] Plane 2 is the input device image layer generated by the light source projection module.

[0100] It should be noted that the projections of plane 1 and plane 2 on the user input surface should have the same size.

[0101] Image Sensor:

[0102] like Fig.14 As shown, the image sensor includes an optical capture module and an IR infrared filter module, wherein:

[0103] When the detection light module detects a disturbance, the central processing unit enables the optical capture module, so that the optical capture module captures the reflected light information through the IR infrared filter module, and transmits the captured reflected light information to the central processing module, so that the central processing module determines the button corresponding to the reflected light information.

[0104] In some embodiments, the micro-vibration module is connected to the detection light module. When the detection light module detects the excitation light emitted by the micro-vibration module, the central processing module enables the micro-vibration module to vibrate.

[0105] Once the user's finger clicks and passes through plane 1, the laser beam is reflected back to the device as reflected light. During this process, whenever plane 1 is disturbed, it means that the user presses one or several keys. At this time, the reflected light is received by the detection light module and sent to the central processing module for processing, enabling the corresponding optical capture module to capture the image of the user's input surface at this time, and return it to the central processing module for processing and analysis to determine which parts of the keys the user has clicked, thereby obtaining the corresponding input information, and transmitting this input information in the form of operation information to the corresponding device terminal for corresponding operations.

[0106] Here, an IR infrared filter module is set in front of the optical capture module to reduce the interference of external light changes on the module.

[0107] When the user clicks, the vibration module on the user's finger emits excitation light which is also detected by the light monitoring module. After being detected by the central processor, the vibration module on the user's finger vibrates, making the user feel a tapping sensation like typing on a keyboard.

[0108] like Fig.15 As shown, Fig.15 This is a schematic diagram of the principle of a micro vibration module, which is used to generate slight vibrations. The module is mounted on the end of the user's finger. When the user clicks below the projection plane 1, the module will vibrate, so that the user's corresponding finger will receive vibration information, just like really touching a physical keyboard.

[0109] Touch input module:

[0110] The entire input device consists of an imaging device and an imaging pen.

[0111] The writing surface of the imaging device is completely covered by electrode capsules (positive or negative). When writing with an imaging pen, the imaging pen provides enough energy to polarize the electrode capsules, forming text or images on the imaging device. The imaging device shown in 16 has an area of ​​8.8×4.4cm2 and is divided into 8 pieces of 2.2×2.2cm2. 1 / 8 imaging device combination:

[0112] like Fig.17 As shown, each 1 / 8 imaging device is composed of a monomer group with an array of 110×60. Each monomer of the 1 / 8 imaging device contains a number of imaging capsules. The display array formed in this way is used to provide imaging device display. When a monomer is subjected to a certain electric field, the polar particles in all the capsules undergo electrophoretic movement. When subjected to a negatively charged electric field, the white particles will "float" to the surface. When a negatively charged imaging pen is drawn across the imaging device, the monomers subjected to the electric field will appear white, leaving traces on the imaging device. Then, holding the imaging pen, you can write. Applying this method to eight small imaging devices, the entire imaging device can display text and graphics. (The lines in the 1 / 8 imaging device are only drawn for the intuitiveness and readability of the manuscript. The imaging device in reality looks like a pure black imaging device, without any lines.)

[0113] The imaging pen is a necessary auxiliary item for the imaging device during use. Without the pen, you cannot write. In order to achieve the display function of the display monomer, the role of the imaging pen is to make the charged monomer particles undergo an electrophoretic effect under the action of the electric field force, so that the white particles "stand out", thereby showing the written image and text on the imaging device. Its overall block diagram design is as follows Fig.18 As shown:

[0114] The physical simulation of the imaging pen is as follows Fig.19 As shown. When the imaging pen writes on the imaging device, the pen tip is subjected to pressure, causing the piezoelectric ceramic to produce a piezoelectric effect and accumulate piezoelectric polarization energy. The circuit part is the piezoelectric sensing circuit that drives the LED to emit light with the excitation generated by the piezoelectric ceramic, and the photons generated by the LED excite the photomultiplier tube to work, generating a large output current. The voltage multiplier circuit amplifies the voltage and drives the tip to discharge, causing electrophoresis to move, so as to achieve the purpose of displaying the image and text on the imaging device. Among them, there is a groove in the pen head, and the needle tip is located in the groove. This design is to protect the needle tip from direct contact with the imaging device and damage the needle tip or the imaging device. The design of the erasing module is similar to that of the needle tip, except that there are more grooves and needle tips to achieve the purpose of increasing the erasing surface.

[0115] The following is an analysis of each link one by one:

[0116] Discharge tip:

[0117] The dense charge that appears at the end of the rotor blades begins to generate ions, and centrifugal force causes the rotor to rotate at a very high speed. Since the effective emission area of ​​the ions is equal to the area of ​​the rotating rotor, the ions achieve a very high speed. In this way, charge neutralization is minimized and a large ion current is generated. The output of the device can be approximated by the coulomb charge equal to the current multiplied by the time. Each coulomb has about 6.25×10 18 The maximum current of the emitter is 400 μA, so the device can generate 6.55×10 18 ×400×10 -6 =2.5×10 15 A charge.

[0118] The high voltage generates negative charges at the sharp emission points of the rotor blades. The reaction force of the emitted ions causes the rotor to rotate, and due to the high charge density at the tip, these ions are directed to the rotor tip and escape into the airflow (for the same potential, the tip has a higher charge density than a sphere with a larger radius). By keeping the voltage low and obtaining sufficient charge density, the negative charges escape into the charge collection module.

[0119] The high voltage difference causes charge repulsion, which generates ions from the tip of the rotor. These ions move at a moderate speed and react to spin the rotor at very high speeds. The rotor is made to size from thin sheet metal, with the upright thumbtacks centered on the needle bearing bolts or nuts. The rotor must be very well balanced to achieve very high speeds.

[0120] The discharge lead "freezes" the motion of the centrifuge by discharging sparks onto the rotating metal sheets.

[0121] Piezoelectric Sensors:

[0122] Piezoelectric ceramic properties. Piezoelectric ceramics have positive piezoelectric effect and inverse piezoelectric effect. As shown in the piezoelectric effect diagram, when piezoelectric ceramics are deformed by external force in a certain direction, polarization will occur inside, and opposite positive and negative charges will appear on two relative surfaces. When the external force is removed, it will return to an uncharged state. This phenomenon is the positive piezoelectric effect. When the direction of the force changes, the polarity of the charge also changes. On the contrary, when an electric field is applied in the polarization direction of the dielectric, these dielectrics will also deform. After the electric field is removed, the deformation of the dielectric disappears. This phenomenon is called the inverse piezoelectric effect. This embodiment refers to the principle of the positive piezoelectric effect. A piezoelectric sensor is constructed based on the piezoelectric effect of the dielectric. When the imaging pen writes on the imaging device, the piezoelectric sensor is subjected to pressure, generates voltage, and stimulates the imaging pen to start working.

[0123] Principle of piezoelectric sensing circuit. According to the characteristics of piezoelectric ceramics, the electrical signal generated by our writing is intermittent, weak and very unstable. The voltage generated can only make the circuit work instantaneously. The writing will be "ink interrupted" and the imaging pen cannot write smoothly. In this regard, we design a piezoelectric sensing circuit, such as Fig. 20As shown, the electrical signal needs to be properly processed by the voltage stabilization, amplification, and filtering circuits to provide stable energy to the LED. When the piezoelectric ceramic generates instantaneous excitation, the circuit generates a continuous and stable voltage, which lasts for T seconds. When this T time is set within an appropriate range, the imaging pen can work smoothly during writing. At the same time, when the writing stops after T time, the circuit stops working and enters the power saving mode. Its circuit diagram is shown in 20. The piezoelectric sensing circuit, U1 is a pressure point ceramic group. The excitation it generates is filtered by C1 and R1. The signal is amplified by the common emitter amplifier circuit composed of Q2, R2, and R4. C4 and D3 constitute a voltage stabilization circuit to stabilize the amplified signal within a suitable range. Finally, the signal is amplified by the common collector amplifier circuit composed of Q1, R6, and R5, and then transmitted to the SCR thyristor. The SCR changes from off to on, so that the LED is turned on and emits light, controlling the on and off of the LED. The light is output to the photomultiplier circuit (next level circuit). In the circuit, C2, C3, and R3 form a circuit to eliminate the interference of the secondary amplification on Q2. The value of T can be determined by the time constant of the first-order circuit. The specific parameters are determined according to the characteristics of the circuit. In this way, the intermittent signal can be converted into a continuous and stable voltage signal, achieving the expected purpose.

[0124] Photomultiplier tube:

[0125] The function of the photomultiplier tube is current amplification (gain). This circuit is already a very mature circuit. When the LED of the upper circuit generates photons acting on the photocathode, as the input and output signals, the photoelectrons emitted by the photocathode are accelerated by the electric field and hit the first dynode, and then secondary electron emission occurs, generating an electron flow. The electron flow emitted by these secondary electrons is accelerated and hits the next dynode, and another secondary electron emission generates more electron flow. Repeating this process continuously will generate a huge number of electron flows, until the secondary electron emission of the last dynode is collected by the anode, thereby achieving the effect of current amplification and generating enough charge. In this way, the small photoelectron current generated by the cathode of the photomultiplier tube is amplified into a larger anode output current, achieving the effect of current amplification. Output to the next circuit (voltage multiplication). In the circuit system, the source of energy is the energy storage element, which is a light signal when input and output, and a current signal when output. This is the working principle of the photomultiplier tube.

[0126] Voltage doubler circuit:

[0127] The function of the voltage multiplier circuit is to amplify the voltage. When the photomultiplier provides enough current, the voltage multiplier circuit starts to work. Fig.21The boost circuit shown in the figure has current as input. The voltage is amplified by the amplifier circuit composed of the inductor coil and the triode. At the same time, the circuit converts the amplified signal into AC through the oscillation coil. The voltage can reach several hundred volts. The capacitors C1~C4 and the diodes D1~D4 form a four-fold half-wave voltage rectifier circuit, which can increase the voltage by more than one thousand volts. Then the output end is connected to the driving capacitor Co to drive the imaging pen to work. For the selection of components, the transistor Q uses a 2N5609 silicon NPN medium power transistor, which can also be replaced by 8050, 9013 and other commonly used transistors. D1~D4 uses a 1N4007 silicon rectifier diode. R1~R4 are all RTX-1 / 8W carbon film resistors. C1~C4 are all 0.033UF / 630V polyester capacitors. High-frequency transformer B can be made by yourself: choose 2E19 type ferrite core and matching plastic frame, L1 is wound with φ0.22mm enameled wire for 22 turns, L2 is wound with the same wire for 8 turns, and L3 is wound with φ0.08mm enameled wire for about 1400 turns. Note that the black dots in the figure are the same-name ends, which are wound in the order of head and tail, and one or two layers of thin insulating paper are placed between the windings. This circuit is also widely used to increase the DC small voltage to more than one thousand volts.

[0128] Driver module:

[0129] The function of the driving module is to generate a high voltage and strong electric field, so that electrophoresis occurs under the action of the electric field force to realize image display. Fig. 22 The driving module shown, the high voltage output generated by the upper circuit is the input of the driving module. Its design is composed of two cylindrical metal cylinders inside and outside. It can be regarded as a capacitor Co in the circuit, which can store a considerable amount of charge. In microscopic physical electricity, it is a "metal ball" with an electrostatic equilibrium state on the surface and a needle tip connected to the outside of the cylindrical metal cylinder. When the + and - ports are connected to high voltage, the negative charge will fill the entire capacitor Co. According to the electrostatic balance outside the cylindrical metal cylinder, since the surface area of ​​the needle tip is very small, the charge density is very large, then the negative charge at the needle tip will generate a very strong electric field. The function of this electric field is to attract positively charged white particles, so that electrophoresis moves and displays patterns.

[0130] Charging circuit:

[0131] The energy storage element needs a charging circuit. The circuit design is as follows: Fig.23As shown. The 220V alternating current passes through the bridge rectifier circuit and is converted into a half-wave "positive voltage". The voltage is amplified by the amplifier circuit composed of Q2. L1 and L3 form a coupling coil to transform the voltage, reducing the voltage to an appropriate value to charge the energy storage component. D7 and C3 form a clamp to stabilize the voltage, protect the circuit, and charge the energy storage component. When the energy storage component is saturated, the battery is cut off, the voltage division increases, and the capacitor C3 stores more energy. Due to the coupling of L2 and L3, a feedback coupling circuit is formed to couple the increased voltage of L3 to both ends of L2, so that the voltage across C2 changes, and the gain of Q1 changes. The input voltage of Q2 is divided, and the input of Q2 becomes smaller, which reduces the coupling voltage, thereby reducing the charging voltage and protecting the battery from overcharge and damage. Charging base design Fig.24 As shown, its function is to automatically start the charging circuit and charge the imaging pen when the imaging pen is placed in the pen holder. After the imaging pen is placed in the pen holder, the contact piece A is connected to the GND common ground shell of the imaging pen, and the contact piece B is connected to the charging end. At the same time, there is a physical switch at the contact piece A to start the charging system. This device is placed on one side of the imaging device, such as the charging pen holder in the imaging device.
