The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 to 2, an embodiment of the present invention provides a color-changing instrument, which includes a display screen 101, a glass lens 102, a first housing 201, and a circuit board assembly 401.

The display screen 101 is used for displaying the running parameters of the motorcycle, prompting the current running speed and other indexes of the user, and facilitating the user to control the motorcycle according to the actual conditions. It can be understood that the display screen 101 is provided with a light source, and the content and parameters presented by the display screen 101 are highlighted by the light emitted by the light source, so that the user can observe the content and parameters conveniently. Further, the luminance of display screen 101 is fixed, avoids the user to adjust the viewing effect through the light source luminance of adjusting display screen 101, because the luminance of display screen 101 is fixed, inputs the electric current of display screen 101 invariable, guarantees that display screen 101 is in comparatively steady operating condition all the time, is favorable to promoting the life of display screen 101.

The glass lens 102 is disposed at a distance from the display screen 101, specifically, the glass lens 102 covers the surface of the display screen 101, and the glass lens 102 is closer to the user than the display screen 101. It will be appreciated that the display surface of the display 101 faces in the direction of the user and that the light source on the display surface conveys information to the user in the form of light. The display surface of the display screen 101 is close to the glass lens 102, the back surface of the display screen 101 is far away from the glass lens 102, and light passes through the glass lens 102 for the user to watch. Since the brightness of the display screen 101 is constant, the transmittance of the glass lens 102 varies with the applied voltage in order to adapt to different external ambient light. Specifically, when the intensity of the ambient light is high, a first voltage is applied to the glass lens 102, and the glass lens 102 is transparent, that is, has high transmittance, so that a user can clearly see parameters on the display screen 101; when the intensity of the ambient light is low, a second voltage is applied to the glass lens 102, and the glass lens 102 has a dark color, i.e., has low transmittance, so as to prevent glare. Under any ambient light, the glass lens 102 automatically adjusts the transmittance, ensuring the viewing experience of the user.

As shown in fig. 3, the display screen 101 is disposed within the first casing 201, and the glass lens 102 is disposed within the first casing 201, that is, the first casing 201 surrounds the display screen 101 and the glass lens 102, and limits the radial positions of the display screen 101 and the glass lens 102. Specifically, the first end inner wall of the first housing 201 is provided with a first protruding portion 202, and the edge of the glass lens 102 abuts against the first protruding portion 202, so as to define the axial position of the glass lens 102 and avoid the glass lens 102 from falling off from the range of the first housing 201 accidentally. The first housing 201 and the first protruding portion 202 are integrally formed, so that the relative position between the first protruding portion 202 and the first housing 201 is stable, and the relative position between the glass lens 102 and the first housing 201 is stable.

In some examples, the first end inner wall of the first housing 201 is provided with a second protruding portion 203, the first protruding portion 202 is spaced apart from the second protruding portion 203, and the second protruding portion 203 is disposed between the display screen 101 and the glass lens 102. On the one hand, the second protruding portion 203 further limits the axial position of the glass lens 102, and on the other hand, the second protruding portion 203 prevents the display screen 101 from contacting the glass lens 102, which affects the operation of the light source on the display screen 101. It is understood that the glass lens 102 is disposed between the first convex portion 202 and the second convex portion 203, and the first convex portion 202 and the second convex portion 203 clamp the edge of the glass lens 102. Specifically, the second protruding portion 203 is integrally formed with the first housing 201, and the relative position between the second protruding portion 203 and the first housing 201 is ensured to be stable, so that the relative position between the glass lens 102 and the first housing 201 is further ensured to be stable.

The circuit board assembly 401 is electrically connected with the glass lens 102, a specific voltage is applied to the glass lens 102, and the transmittance of the glass lens 102 is changed due to the difference of the voltage, so that the display brightness of the color-variable instrument is indirectly changed. Since the circuit board assembly 401 is connected to the glass lens 102 and the display screen 101, respectively, the current in the line connected to the display screen 101 is approximately kept constant to ensure the stable operation of the display screen 101, and at the same time, the voltage in the line connected to the glass lens 102 is continuously changed to adjust the brightness of the color-changing instrument.

Specifically, when the ambient light is strong, a first voltage is applied to the glass lens 102, and when the ambient light is weak, a second voltage is applied to the glass lens 102. It will be appreciated that the optical sensor 402 is electrically connected to the circuit board assembly 401 to transmit signals.

In some examples, a mounting hole is formed in the glass lens 102, the optical sensor 402 is disposed in the mounting hole, since the optical sensor 402 needs to sense the illumination intensity of the external environment, the light-sensing end of the optical sensor 402 is located outside the glass lens 102, and the connecting end of the optical sensor 402 is electrically connected to the circuit board assembly 401.
