Description

Technical Field

[0001] This utility model relates to the field of touch screen control technology, and in particular to a resistive touch screen combination switch system for electric two-wheeled vehicles and an electric bicycle. Background Technology

[0002] Existing electric two-wheeler switch systems suffer from the following technical drawbacks: Mechanical switches have limitations: most electric two-wheeler switches are mechanical switches. Mechanical switches offer limited interaction functions and cannot support complex interactions such as sliding; they also have low reliability, are susceptible to environmental corrosion and wear, and have a short lifespan. Capacitive touch switches are expensive and have poor anti-interference capabilities. Capacitive touch switches, which have emerged in recent years, work by utilizing the electrical current sensing of the human body. They detect the touch position through the tiny capacitance formed between the electrodes on the touchscreen and the finger. Capacitive touch switches offer relatively rich and intelligent interaction functions, but this method is expensive and has poor anti-interference capabilities (it cannot be recognized when exposed to rain, gloves, etc.). Therefore, existing electric two-wheeler switch systems suffer from high cost and low reliability. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0031] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0032] Figure 1 This is a schematic diagram of the structure of a resistive touch screen combination switch system for an electric two-wheeled vehicle according to an embodiment of the present invention. Figure 2 This is a circuit block diagram of a resistive touch switch system for an electric two-wheeled vehicle according to an embodiment of the present invention, with reference to... Figure 1 and Figure 2 The present invention provides a resistive touch screen combination switch system for electric two-wheeled vehicles. The resistive touch screen combination switch system for electric two-wheeled vehicles includes: a resistive touch screen 10, a data acquisition and AD conversion module 20, and a main control module 30.

[0033] The resistive touch screen 10 is connected to the data acquisition and AD conversion module 20. The resistive touch screen 10 is used to acquire the switch signal generated when the user physically presses the screen and send it to the data acquisition and AD conversion module 20.

[0034] The acquisition and AD conversion module 20 is connected to the main control module 30. The acquisition and AD conversion module 20 is used to identify the switching signal and convert it from analog to digital to a digital voltage signal, and then transmit it to the main control module 30.

[0035] The main control module 30 is connected to the vehicle-side control device. The main control module 30 is used to identify the validity of the digital voltage signal, determine the valid switch signal, and transmit it to the vehicle-side control device. The vehicle-side control device is used to respond to the corresponding switch action command based on the valid switch signal.

[0036] Specifically, the resistive touchscreen combination switch system for electric two-wheelers is a complete embedded electrical system. The resistive touchscreen 10 can be a matrix resistive screen, or a five-wire resistive screen can be used instead, increasing redundant electrodes to improve lifespan. The data acquisition and AD conversion module 20 can be an integrated chip, and the main control module 30 can be a main control MCU. The acquired switch signal is the voltage signal generated when the user physically presses the resistive touchscreen 10. The integrated chip identifies and converts the switch signal before sending it to the main control MCU. The main control MCU interacts with other electrical components in the electric two-wheeler. Through wired / wireless communication with the vehicle body, it interacts with various core electrical components, achieving a low-cost, high-quality, and intelligent design for the electric two-wheeler switch. It can realize single-point touch, multi-point combined touch, force-assisted sliding control of complex vehicle-side functions, and custom gesture parsing and input functions.

[0037] The integrated chip collects the coordinates of the switch signal generated when the user physically presses the button. After the integrated chip performs AD conversion, the signal is sent to the main control MCU via IIC and GPIO ports to obtain the touch information. The main control MCU judges the validity of the touch information. Invalid or erroneous information is discarded, while valid information is executed. The corresponding switch signal is sent to the core electrical components of the electric two-wheeler via wireless or wired communication for subsequent switch action command responses.

[0038] The resistive touchscreen 10 is a four-layer transparent composite film screen. The bottom layer is a base layer made of glass or acrylic glass; the top layer is a plastic layer with a hardened outer surface for smoothness and scratch resistance; the middle layer consists of two conductive metal layers, separated by numerous tiny transparent insulating dots. These two conductive metal layers form the working surface of the touchscreen, each end coated with a strip of silver paste, forming a pair of electrodes on the working surface.

[0039] The resistive touchscreen 10 has its X and Y working surfaces mounted on two conductive layers, with four leads connecting to the X and Y electrode pairs respectively. When a finger touches the screen, the two conductive layers make contact at the contact point. Essentially, the resistive touchscreen works by measuring the voltage drop across the resistance in the X and Y directions to determine the touch point coordinates, and then mapping these coordinates to the function switches of the electric two-wheeled vehicle, thus enabling human-computer interaction.

[0040] The working surface of the resistive touch screen 10 is completely isolated from the outside world, and is less affected by the environment. Therefore, it has the advantages of being resistant to dust and moisture, having high stability, and not drifting.

[0041] The technical solution of this utility model provides a low-cost, high-reliability intelligent touch switch system, which solves the shortcomings of traditional mechanical switches used in electric two-wheelers, such as limited functionality and insufficient intelligence. It supports single-point, multi-point, and sliding combination operations through a matrix resistive screen and custom gesture logic. It also addresses the drawbacks of capacitive switches used in electric two-wheelers, such as high cost and poor anti-interference capability. This results in a low-cost, high-reliability touch interaction system, improved environmental adaptability (waterproof, dustproof, and vibration-resistant), and an upgrade in switch quality and interactive intelligence for electric two-wheelers. In summary, this utility model solves the problems of high cost and low reliability in existing electric two-wheeler switch systems.

[0042] Figure 3 This is a structural schematic diagram of a resistive touchscreen according to an embodiment of the present invention, with reference to... Figure 3 Optionally, the resistive touchscreen 10 includes:

[0043] Silkscreen panel 11;

[0044] Capacitor FPC12 is disposed on one side of silkscreen panel 11;

[0045] A resistive touch sensor 13 is located on the side of the capacitive FPC12 away from the silkscreen panel 11. The resistive touch sensor 13 is connected to the data acquisition and AD conversion module.

[0046] Specifically, the resistive touchscreen combination switch system for electric two-wheeled vehicles consists of: a silkscreen panel 11, a capacitive FPC 12, a resistive touch sensor 13, a data acquisition and AD conversion module (integrated chip), and a main control module (main control MCU). The resistive touchscreen 10 is modularly packaged, and its tri-proof coating offers advantages such as waterproofing, dustproofing, and corrosion resistance.

[0047] By communicating with the vehicle's core electrical components via wired / wireless communication, the switch for the electric two-wheeled vehicle achieves a low-cost, high-quality, and intelligent design. It can realize complex vehicle-side functions such as single-point touch, multi-point combined touch, and force-assisted sliding control, as well as custom gesture parsing and input functions.

[0048] The resistive touch sensor 13 enables precise coordinate detection through pressure touch, supports operation with gloves and wet hands, has low hardware cost, and can realize complex intelligent control through single-point, multi-point, and sliding combination operations.

[0049] The screen-printed panel 11 can be an acrylic panel. The acrylic panel, together with the functional screen-printed icons, clearly demonstrates the touch switch function. Existing capacitive screen glass substrates are fragile, while acrylic panels have good weather resistance and impact resistance.

[0050] Customized touch gestures can be input via resistive touch sensor 13 and APP, enabling customized switch interaction functions, allowing for a unique switch experience for each user.

[0051] Continue to refer to Figure 3 Optionally, the resistive touch sensor 13 includes:

[0054] The FPC133, located on the side of the steel sheet 132 away from the double-sided adhesive 131, and the capacitor FPC12 are used to generate a switch signal when the user physically presses it.

[0055] Specifically, when the user presses the button switch on the silkscreen panel 11 of the resistive touch sensor 13, the FPC133 and the capacitor FPC12 will generate a switching signal.

[0056] Figure 4 This is a schematic diagram of an installation application screen printing panel according to an embodiment of the present utility model, with reference to... Figure 4 Optionally, the buttons on the silkscreen panel 11 include: multimedia button 111, horn button 112, cruise control button 113, gear mode up button 114, gear mode down button 115, hazard light button 116, headlight switch button 117, and parking button 118.

[0057] Specifically, here's an example of button operation: While riding at 30km / h, touch the "Cruise Control Button" icon. The main control MCU will analyze and recognize the signal, sending a valid cruise control signal trigger message to the vehicle's motor controller and instrument panel to enter cruise control mode and display the fixed speed of 30km / h. In cruise control mode, a single touch of the "+" icon will cause the main control MCU to analyze and recognize the signal, sending a valid "+" message to the motor controller to increase the cruise speed by 5km / h, resulting in a cruise speed of 35km / h. Then, touch and hold the "+" icon for 1 second, slide it to the right to the middle position, hold for 3 seconds, and exit. This will activate the continuous cruise control speed stacking function, increasing the cruise speed by 15km / h, resulting in a cruise speed of 50km / h.

[0058] It can also support remote gesture customization (OTA upgrade) through modules such as Bluetooth, Wi-Fi, and 4G to increase and expand touch gestures.

[0059] The integrated design of matrix resistive touch screen and gesture logic enables low-cost, intelligent and highly stable combined logic for electric two-wheelers, and realizes the application of single-point, multi-point, long press plus swipe and custom gesture settings combined logic.

[0060] Continue to refer to Figure 4 Optionally, the multimedia buttons 111 include: an up button 1111, a down button 1112, a left button 1113, a right button 1114, a back button 1115, a settings button 1116, and an confirmation button 1117.

[0061] Specifically, the multimedia buttons are mainly used to interact with the first, second, and third level menus in the vehicle's TFT smart instrument panel.

[0062] An embodiment of this utility model also provides an electric bicycle, which includes the electric two-wheeled vehicle resistive touch screen combination switch system of any embodiment of this utility model.

[0063] Since the electric bicycle includes the electric two-wheeled vehicle resistive touch screen combination switch system provided in any embodiment of this utility model, the beneficial effects of the electric bicycle and the electric two-wheeled vehicle resistive touch screen combination switch system are the same, and will not be repeated here.
