Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle body color changing, in particular to a vehicle body color changing control method, a vehicle body color changing device and a vehicle. BACKGROUND

[0002] In recent years, there are mainly several schemes for vehicle body color changing:

[0003] The first existing scheme: liquid crystal glass, also known as electrically controlled light-adjusting glass. This glass can change from ordinary glass to frosted glass in an instant to achieve the purpose of protecting privacy. In fact, there is a liquid crystal layer between two ordinary glasses. The liquid crystal is in regular arrangement under the condition of being electrified, and is in irregular arrangement under the condition of not being electrified, the former keeps the normal transmission of light, and the latter blocks the transmission of light.

[0004] The technology has the following problems:

[0005] 1. The technology supports only a single color, and currently only supports three colors of "black, white and gray".

[0006] 2. The liquid crystal is relatively fragile on the vehicle and cannot withstand collision and scratching, because collision will damage the liquid crystal circuit, and the maintenance cost is extremely high.

[0007] The second existing scheme: special paint that changes color with different visual angles. The paint contains a substance called "mica" that causes light to refract and diffract, and it is not the paint that contains different colored pigments, but ordinary paint relies on the reflection of pigments.

[0008] The technology has the following problems:

[0009] 1. This multiple color-changing car requires an additional coating in the manufacturing process compared to ordinary metal paint, otherwise it cannot change color.

[0144] The preset vibration scheme generating module is used to generate a preset vibration scheme according to the preset color.

[0145] The signal generating module is used to generate a vibration signal and a color change device driving signal according to the preset vibration scheme.

[0146] The signal sending module is used to send the vibration signal to a vibration device arranged on the vehicle to make the vibration device vibrate, and send the color change device driving signal to an electrophoretic driving color change device; wherein,

[0147] The electrophoretic driving color change device changes color under the control of the color change device driving signal and the vibration frequency emitted by the vibration device.

[0148] The application also provides a vehicle, which comprises a vehicle body, PDMS-coated PDMS films, a vehicle body color changing control device, an electrophoretic driving color changing device and a vibration device, wherein

[0149] The PDMS-coated PDMS films are attached to one or more of the vehicle doors, vehicle windows and sunroofs of the vehicle body.

[0150] The vehicle body color changing control device is the vehicle body color changing control device as claimed in claim 8, and is used in combination with the PDMS-coated PDMS films.

[0151] The electrophoretic driving color changing device is used in combination with each of the PDMS-coated PDMS films, and is used to supply power to each of the PDMS-coated PDMS films.

[0152] The vibration device is installed on the vehicle body, and is used to provide vibration for each of the PDMS-coated PDMS films.

[0153] Referring to Figure 3 and Figure 4 In this embodiment, each of the PDMS-coated PDMS films comprises a plurality of pixels, and the principle of a single pixel is as follows: each pixel is a small microfluidic chip, each microfluidic chip has three grooves for storing RGB color particles, the three color particles are of different sizes, and the movement of the particles in the microfluidic chip is controlled by applying a voltage through an electrode, so as to drive the color particles representing RGB three primary colors to move to a designated channel area for mixing, and different colors are mixed according to different mixing proportions.

[0154] When a reverse voltage is applied, the particles are sorted and separated according to their sizes, and since the acoustic radiation force is proportional to the third power of the particle radius, the larger the particle is, the greater the force acting on the particle is, and then the faster the particle moves, which can be used for sorting particles of different sizes. The mixed particle solution is exposed to the acoustic force. Compared with smaller particles, larger particles move faster to the pressure node. Particles of different sizes are located at different positions in the microfluidic channel. Particles of different sizes have different outlets, so it is easy to sort the particles.

[0155] In this embodiment, the number of vibration devices is a plurality, and one vibration device is used to provide vibration for one PDMS-coated PDMS film.

[0156] The application will be further described in detail by way of examples, and it can be understood that the examples do not constitute any limitation on the application.

[0157] The driver's emotion is recognized by image acquisition, the emotion classification and emotion level are determined, for example, the emotion is considered to be an excited emotion, information represented by the excited emotion is taken as an input parameter of the color change of the vehicle body, and the vehicle speed is also taken as an input parameter of the color change of the vehicle body.

[0158] As Figure 4 , the right three grooves are connected with transparent electrodes representing SOURCE, which are three color control electrodes representing red, green and blue (the largest represents red, the smallest represents blue, and the medium represents green, Figure 3 which are the same as the colors represented in Figure 4 ), and the left side is a transparent electrode representing GATE. When no voltage is applied, the three-color particles are at rest in the three microfluidic grooves, and the proportion of the three primary colors presents white.

[0159] As Figure 4 , when the right three grooves are applied with positive voltage and the left side is applied with negative voltage, due to the existence of the double electric layer, electroosmotic flow (electroosmosis refers to the phenomenon that the liquid in the microchannel moves along the inner wall of the channel under the action of the electric field) is formed. The three kinds of particles enter the middle area and mix. According to the duration of the positive voltage, the number of RGB three-color particles entering the middle area is different. According to the RGB ratio, the overall color after mixing is presented.

[0160] As Figure 3 , the left side is applied with positive voltage and the right side is applied with negative voltage, so that the electroosmotic flow moves from left to right, driving the color particles. The automobile vibration sound wave applies different sound wave forces to the three different sizes of particles, so that the particles move at different speeds and enter different grooves to achieve the purpose of separation, and the overall presents white.

[0161] Among them, the automobile vibration sound wave is generated by the staggered frequency converter composed of electrodes installed on both sides of the microfluidic chip channel. According to the size of the color particles and the width, length and gravity of the microfluidic chip channel, the frequency and time interval of the vibration sound wave are adjusted. The surface acoustic wave formed on the surface of the microfluidic chip propagates, and the pressure amplitude in the center of the microfluidic channel is the smallest, and the pressure amplitude on the wall surface of the microfluidic channel is the largest. By adjusting the frequency of the sound wave to adjust the size of the sound wave radiation force, the three color particles passing through the center of the channel are aligned to different pressure nodes, so as to realize accurate separation of the color particles.

[0162] It can be understood that the above description of the method also applies to the description of the device.
