Description

Technical Field

[0001] This utility model relates to the field of motorcycle parts technology, and in particular to a motorcycle instrument panel. Background Technology

[0002] In motorcycle design and manufacturing, the dashboard serves as a crucial information interface between the rider and the vehicle. Its diverse functions and level of integration directly impact the safety and convenience of the riding experience. The motorcycle's dashboard displays information such as speed, mileage, fuel level, and steering indicators, allowing riders to better understand the motorcycle's status while driving.

[0003] A search revealed that Chinese utility model patent CN217864511U discloses a motorcycle dashboard, comprising: a motorcycle LCD instrument panel with a wiring harness, wiring harness terminals, and a flange at the upper end; a bottom shell; an upper shell connected to the bottom shell at the lower end; a waterproof and breathable component mounted on the bottom shell; and a mounting component; the flange presses against the upper end of the upper shell, and the motorcycle LCD instrument panel is detachably connected to the bottom shell. The described motorcycle dashboard is easy to install, has good waterproof and breathable performance, and the inner surface of the instrument panel lens is not prone to fogging.

[0004] For example, Chinese utility model patent CN216468226U discloses a multi-functional motorcycle instrument panel. A motorcycle path locator allows for location tracking and querying of the motorcycle's path as needed. The instrument panel data plug is inserted into the motorcycle's connector to connect the instrument panel to the motorcycle, thus establishing a circuit connection. The instrument panel circuit board assembly connects to the motorcycle's processor via a connection connector, displaying the information on the instrument display. A positioning rod is fixedly connected to the rear surface of the instrument panel housing, effectively ensuring proper positioning during installation and preventing misalignment and tilting issues common during installation.

[0005] While the existing motorcycle instrument panel meets basic usage requirements, it cannot control the turn signals to flash rapidly during emergency braking to alert following vehicles to any abnormalities, thus compromising driving safety. Therefore, further improvements to the existing technology are necessary. Utility Model Content

It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0022] like Figure 1-3 As shown, the motorcycle instrument panel includes an instrument housing 1, on which an LCD screen 2 is mounted. Inside the instrument housing 1 is a main control circuit board 3 electrically connected to the LCD screen 2. The main control circuit board 3 includes a vehicle speed signal input circuit, a vehicle speed signal sampling circuit, a vehicle speed signal processing circuit, an MCU main control circuit, and a turn indicator circuit. The vehicle speed signal sampling circuit is electrically connected to both the vehicle speed signal input circuit and the vehicle speed signal processing circuit. The MCU main control circuit is electrically connected to both the vehicle speed signal processing circuit and the turn indicator circuit. It can be understood that the instrument housing 1 includes a bottom shell 4, an outer frame 5, a circuit board mounting frame 6, and a front cover 7. The main control circuit board 3 and the LCD screen 2 are both mounted inside the bottom shell 4. The outer frame 5 is fitted over the outer side of the LCD screen 2. The main control circuit board 3 is mounted on the circuit board mounting frame 6, and the front cover 7 is mounted on the front end of the outer frame 5.

[0023] Specifically, the vehicle speed signal input circuit includes a signal input interface J2, and the vehicle speed signal sampling circuit includes resistors R6, R7, R11, R12, diode D6, capacitors C5 and C6, and transistor Q2. Resistor R6 is connected to diode D6, signal input interface J2, capacitor C5, and resistor R11, and transistor Q2 is connected to resistors R7, R11, R12, and capacitor C6. The vehicle speed signal processing circuit includes a signal processing chip U7, resistors R14 and C24, resistor R32, and resistor R39. Resistor R14 and capacitor C24 are both connected to transistor Q2, resistors R32 and R39 are both connected to resistor R6, and resistors R14, C24, R32, and R39 are all connected to the signal processing chip U7. Understandably, the vehicle speed signal is connected from the fourteenth pin of the signal input interface J2 and input to resistor R11 and transistor Q2. Then, it is input to the first pin of the signal processing chip U7 through resistor R14. The signal processing chip U7 can be an LM358 chip, etc., which is used to amplify the vehicle speed signal and send it to the MCU main control circuit.

[0024] Specifically, the MCU main control circuit includes a microcontroller chip U3, a data storage chip U6, a resistor R28, and capacitors C21 and C22.

The data storage chip U6 could be an M24C08 chip, etc., used to store the corresponding driving data. In practical applications, a 12V positive signal line can be added, with the following functional logic: When the 12V positive signal line is powered on, if the condition of "vehicle speed signal within 800 milliseconds and reduction ratio of 10%" is met, the left and right turn indicator lights will flash simultaneously at 500 millisecond intervals; when the 12V positive signal line is powered off, the synchronous flashing function of the left and right turn indicator lights will be automatically deactivated, enabling the turn signals to flash rapidly during emergency braking to remind following vehicles of abnormalities in front of them. This dangerous warning is triggered when the vehicle speed ratio reaches a certain proportion within the effective braking time, and will not be displayed under normal automatic conditions.

[0025] Understandably, this utility model has a reasonable design and unique structure. It detects vehicle speed signals by setting up a vehicle speed signal sampling circuit, performs signal conversion processing on the vehicle speed signal by a vehicle speed signal processing circuit, and then identifies the change state of the vehicle speed signal by the MCU main control circuit to determine whether there is an emergency braking operation. In turn, it outputs a control signal to control the turn signals on the turn indicator circuit to flash rapidly, reminding vehicles behind to pay attention to the abnormality of the vehicle in front, thereby improving driving safety. Moreover, it does not require additional parts, does not increase costs, and is relatively easy to achieve mass production and popularization.
