[0002] A compass, also known as a needle-pointing compass or a magnetic compass, is an ancient and important navigation tool used to indicate direction. It is mainly used to determine and maintain the direction of the geographic North Pole, helping navigators determine their course on land and sea.

[0003] Existing compasses are mainly divided into two categories, namely magnetic compasses and gyrocompasses. In addition to the above two types, there are also modern navigation instruments such as electronic compasses, which combine the advantages of traditional mechanical compasses with modern electronic technology to meet the needs of higher precision and automated navigation systems.

[0029] See also Figures 1 to 5 , is a brightness adaptive compass as the best embodiment of the utility model, comprising a main housing 10, an outer disk 20, an inner disk 30, an electronic compass display 40, a switch button 50 and a gyro mechanism 60 arranged at the lower end of the main housing 10, the outer disk 20 and the inner disk 30 are arranged concentrically and a protective glass 70 is covered on the surface of the main housing 10, the inner disk 30 is transmission-connected to the gyro mechanism 60 and can rotate freely relative to the outer disk 20, the outer disk 20 and the inner disk 30 are respectively provided with a plurality of light-transmitting structures 80 penetrating around their respective circumferences, the plurality of light-transmitting structures 80 located on the outer disk 20 and the inner disk 30 respectively form outer circle scales and inner circle scales, the main housing 10 is provided with a backlight module 90 with adjustable luminous intensity at the bottom of the outer disk 20 and the inner disk 30, and the outer surface of the main housing 10 is provided with a photosensitive element 92 electrically connected to the backlight module 90 and used to adjust the luminous intensity of the backlight module 90.

[0030] Preferably, combined Figure 5, and also includes a control module 91. The input end of the control module 91 is electrically connected to the switch button 50 and the photosensitive element 92. The output end of the control module 91 is electrically connected to the electronic compass display 40 and the backlight module 90. In this embodiment, the photosensitive element 92 is a light sensor (such as a Keyence light sensor, etc.), the control module 91 is an STM32 single-chip microcomputer or an MCU microprocessor, the electronic compass display 40 is a display screen module, and the switch button 50 is a button-type switch. Therefore, the light intensity around the main shell 10 is sensed by the light sensor, and then converted into a corresponding electrical signal according to the corresponding light intensity and input into the control module 91. The control module 91 presets a corresponding light intensity comparison threshold. After comparison by the control module 91, the current input to the backlight module 90 is adjusted, so as to control the luminous intensity of the backlight module 90 to meet the requirements, that is, it is automatically adjusted to a low brightness under conditions of high light intensity such as daytime to avoid a strong contrast with the external light source; at night or in a dim environment, the brightness is increased to ensure clear reading.

[0031] Preferably, the backlight module 90 is a light-emitting backboard carrying an LED lamp bead matrix, and the distribution of the LED lamp bead matrix is ​​evenly arranged according to the position of the light-transmitting structure 80, so as to ensure the uniformity of the light intensity.

In addition, a light-transmitting glass layer 82 is embedded on one side of the hollow grooves 81 close to the protective glass 70. Thus, the light generated by the backlight module 90 at the lower ends of the outer disk 20 and the inner disk 30 can be uniformly guided out through the hollow grooves 81 and the light-transmitting glass layer 82, so that the overall reading of the compass is convenient and easy to read, and the brightness change of the backlight module 90 can be transmitted in time, which is convenient for users to read.

[0033] Preferably, Figure 4 As shown, the light-transmitting glass layer 82 is a frosted glass plate with one side frosted, and the frosted side is the side close to the protective glass 70. Thus, the light-transmitting and soft-lighting effects are achieved through the frosted glass plate, and the overly transparent light-transmitting glass layer 82 is prevented from showing the internal mechanical structure of the compass, so that the overall reading area of ​​the compass remains beautiful and easy to read.

[0035] Preferably, Figure 4 As shown, the outer surface of the protective glass 70 is covered with an anti-reflection coating 71. In this embodiment, an AR coating is used as the anti-reflection coating 71 to reduce direct light and internal reflections, ensuring that the magnetic needle and scale lines inside the compass can be clearly seen under any lighting conditions.

[0036] Preferably, Figure 1 , 2 As shown, the outer surface of the electronic compass display 40 is covered with anti-reflection glass (not shown in the figure).

[0037] The beneficial effects of the utility model are as follows:

[0038] A backlight module 90 with adjustable luminous intensity is provided at the bottom of the main housing 10, and a photosensitive element 92 (such as a light sensor) is disposed on the outer surface, which can automatically adjust the luminous intensity of the backlight module 90 according to the ambient light intensity, so that the compass information can be clearly read under different lighting conditions;

[0039] The outer disk 20 and the inner disk 30 are provided with a light-transmitting structure 80 in the circumferential direction, forming inner and outer circle scales and numbers, thereby improving visual contrast and recognition;

[0040] Equipped with a control module 91, such as an STM32 single-chip microcomputer or an MCU microprocessor, which is responsible for receiving the signal input from the switch button 50 and the photosensitive element 92, and accordingly controls the display content of the electronic compass display 40 and the luminous intensity of the backlight module 90, thereby realizing intelligent operation and display;

[0041] The outer side of the protective glass 70 is covered with an anti-reflection coating 71, and the outer surface of the electronic compass display 40 is also covered with anti-reflection glass. The double anti-reflection treatment ensures that a good reading effect can be obtained even in a strong light environment.

By automatically adjusting the backlight brightness, optimizing the scale display, and applying anti-reflection technology, the visibility and ease of use of the compass under various lighting conditions are significantly improved. At the same time, combined with the design of the electronic compass display 40, the device has a digital and intelligent navigation function.

[0043] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
