[0031] Please refer to Figure 1 - Figure 9 This embodiment provides a sight with a horizontal indication function, including: The sight body 1 has a receiving cavity 110 on its side wall; The sight body 1 can be an optical sight as in the prior art.

[0032] A horizontal indicator 2 includes a circuit board 210 disposed in the receiving cavity 110, a colored dot-shaped indicator light source 220 electrically connected to the circuit board 210, and a horizontal sensor 230 electrically connected to the circuit board 210. The receiving cavity 110 communicates with the inner cavity of the scope tube 120 of the sight body 1, and the circuit board 210 is disposed in the receiving cavity 110. The colored dot-shaped indicator light source 220 is one or more disposed in the inner cavity of the scope tube 120 of the sight body 1, and is disposed against the tube wall of the scope tube 120. The light emission point of the colored dot-shaped indicator light source 220 is located between the eyepiece 130 and the zoom system 140 of the sight body 1, and the light source of the colored dot-shaped indicator light source 220 is directed towards the eyepiece 130. The circuit board 210 controls one or more of the colored dot-shaped indicator light sources 220 to operate and emit light according to the data collected by the horizontal sensor 230.

[0033] The colored dot-shaped indicator light source 220 emits colored light of a color that has a distinct contrast with the color inside the lens tube 120.

[0034] Example 1 When the horizontal sensor 230 detects that the sight body is level, the circuit board 210 controls one colored dot indicator light 220 to illuminate; otherwise, the colored dot indicator light 220 does not illuminate. Alternatively, when the horizontal sensor 230 detects that the sight body is level, the circuit board 210 controls one colored dot indicator light 220 to remain off; otherwise, the colored dot indicator light 220 illuminates.

[0035] Example 2 When the level sensor 230 detects that the sight body is level, the circuit board 210 controls multiple colored dot indicator lights 220 to illuminate; otherwise, the multiple colored dot indicator lights 220 do not illuminate. Alternatively, when the level sensor 230 detects that the sight body is level, the circuit board 210 controls multiple colored dot indicator lights 220 to not illuminate; otherwise, the multiple colored dot indicator lights 220 illuminate.

[0036] The horizontal sensor 230 can be a small-sized sensor based on existing technologies such as an acceleration sensor or a tilt sensor.

[0037] By placing the circuit board 210 in the receiving cavity 110, the circuit board 210 avoids occupying space in the inner cavity of the scope tube 120. The circuit board 210 can draw power from electrical appliances such as infrared lamps, lighting lamps, and rangefinders attached to the shooting equipment, or it can be equipped with a dedicated battery 250 for power.

[0038] The colored dot-shaped indicator light source 220 is: At least two light-emitting diodes of different colors; Alternatively, it can be one or more color-changing dot indicator lights; The power supply wires of the light-emitting diodes or color-changing dot-shaped indicator lights are laid along the tube wall of the mirror tube 120 and electrically connected to the circuit board 210.

[0039] Example 3 When there are two LEDs, one LED emits green light when it is working, and the other LED emits red light. When the level sensor 230 detects that the sight body is level, the circuit board 210 controls the green LED to emit green light, and the other LED remains inactive. When the level sensor 230 detects that the sight body is not level, the circuit board 210 controls the red LED to emit green light, and the other LED remains inactive.

[0040] In a preferred embodiment, three LEDs are used. The central LED emits green light when it is working, while the LEDs on the left and right sides emit blue and red light, respectively. When the level sensor 230 acquires information indicating that the sight body is leveled, the circuit board 210 controls the central LED to emit green light, while the other two LEDs remain inactive.

[0041] When the horizontal sensor 230 detects that the sight body is tilted to the left, the circuit board 210 controls the left LED to emit blue light, while the other two LEDs remain inactive.

[0042] When the horizontal sensor 230 detects that the sight body is tilted to the right, the circuit board 210 controls the right LED to emit red light, while the other two LEDs remain inactive.

[0043] Light-emitting diodes (LEDs) can use smaller electronic components, have suitable brightness, and operate stably.

[0044] Example 4 The colored dot indicator light source 220 is a color-changing dot indicator light. This color-changing dot indicator light is a dot-shaped miniature surface-mount LED light. Each surface-mount LED light can emit different colors of light according to the settings.

[0045] When the level sensor 230 collects information about the leveled state of the sight body, the circuit board 210 controls a color-changing dot indicator light to emit green light.

[0046] When the horizontal sensor 230 detects that the sight body is tilted to the left, the circuit board 210 controls a color-changing dot indicator light to emit blue light.

[0047] When the horizontal sensor 230 detects that the sight body is tilted to the right, the circuit board 210 controls a color-changing dot indicator light to emit red light.

[0048] Example 5 The colored dot indicator light source 220 consists of multiple horizontally arranged variable color dot indicator lights. The variable color dot indicator lights are miniature dot-shaped surface-mount LEDs, which can emit different colors of light according to the settings.

[0049] When the level sensor 230 collects information about the leveled state of the sight body, the circuit board 210 controls multiple color-changing dot-shaped indicator lights to emit green light together.

[0050] When the horizontal sensor 230 detects that the sight body is tilted to the left, the circuit board 210 controls multiple variable-color dot indicator lights to emit blue light. Specifically, the leftmost variable-color dot indicator light may emit blue light; the greater the leftward tilt detected by the horizontal sensor, the more variable-color dot indicator lights will illuminate blue.

[0051] When the horizontal sensor 230 detects that the sight body is tilted to the right, the circuit board 210 controls multiple variable-color dot indicator lights to emit red light together. In some embodiments, the rightmost variable-color dot indicator light emits red light; the greater the rightward tilt of the attitude data collected by the horizontal sensor, the more variable-color dot indicator lights will illuminate red.

[0052] Example 6 The colored dot-shaped indicator light source includes at least two light-emitting diodes of different colors mounted on the circuit board and light guides of a number corresponding to the number of light-emitting diodes; the lens tube is provided with a through hole communicating with the receiving cavity; the light guide passes through the through hole, with one end connected to the light-emitting diode and the other end located at the light-emitting point.

[0053] Example 7 Please refer to Figure 2 - Figure 9The colored dot indicator light source 220 includes one or more variable color dot indicator lights 221 mounted on the circuit board 210, and light guide tubes 222 in number corresponding to the variable color dot indicator lights 221; the lens tube 120 is provided with a through hole 121 communicating with the receiving cavity 110; the light guide tube 222 passes through the through hole 121, with one end connected to the variable color dot indicator light 221 and the other end located at the light emission point.

[0054] Preferably, the aperture of the through hole 121 is equal to or slightly larger than the outer diameter of the light guide tube 222, which can play a certain positioning role after the light guide tube 222 is installed.

[0055] The light guide tube 222 is preferably an optical fiber tube, which can reduce brightness loss, has high light guiding efficiency, low cost, good strength and stability, is easy to deploy, and has a small size. When the user observes the shooting target through the eyepiece 130, one or more light guide tubes 222 are set close to the tube wall of the lens tube 120, and basically do not obstruct the user's field of vision. The user can simultaneously observe the target being shot and the colored dot indicator light 220 emitting corresponding colored light to understand the tilt attitude of the current shooting equipment, thus improving the user experience.

[0056] Preferably, the light guide tube 222 is arranged along the wall of the lens tube 120 to avoid excessive appearance in the field of view, which would cause interference.

[0057] In addition to the scheme of the colored dot indicator light source 220 including one or more variable color dot indicator lights 221 on the circuit board 210 and light guide tubes 222 in number corresponding to the variable color dot indicator lights 221, the colored dot indicator light source 220 can also be composed of miniaturized LEDs set at the light emission point. The miniaturized LEDs are arranged along the tube wall of the mirror tube 120 through wires to be electrically connected to the circuit board 210.

[0058] Please refer to Figure 4 and Figure 7 It shows that there are five colored dot-shaped indicator light sources 220, distributed along the upper edge of the support ring 240. Figure 8 and Figure 9 Different numbers of colored dot indicator light sources 220 and their positions relative to the support ring 240 are shown. The number and position of the colored dot indicator light sources 220 can also be selected in other ways, all of which fall within the range where one or more colored dot indicator light sources 220 are located inside the scope tube 120 of the sight body 1 and are disposed against the tube wall of the scope tube 120.

[0059] Please refer to Figure 2 and Figure 4 , Figure 5The horizontal indicator 2 includes a support ring 240, which is connected to the tube body of the zoom system 140; the support ring 240 sets the light output end of the light guide tube 222 at the light output point.

[0060] Please refer to Figure 2 The light guide tube 222 is a tube body between the through hole 121 and the support ring 240, located between the inner wall of the lens tube 120 and the outer wall of the tube body of the zoom system 140.

[0061] The light guide tube 222 extends from the through hole 121 to the support ring 240, forming the light guiding path of the light guide tube 222. This part of the light guide tube 222 is located between the inner wall of the lens tube 120 and the outer wall of the tube of the zoom system 140, avoiding its presence in the observation cavity of the eyepiece 130 or the tube of the zoom system 140, thus avoiding space occupation and interference with the field of view.

[0062] Please refer to Figure 2 and Figure 3 The outer wall of the lens tube 120 extends into a sleeve 122, which together with the lens tube 120 encloses the receiving cavity 110; the opening of the sleeve 122 is detachably connected to an end cap 150.

[0063] Preferably, a sealing ring is provided at the opening of the sleeve 122, so that the end cap 150 has a good sealing degree after being connected to the opening of the sleeve 122.

[0064] Please refer to Figure 2 and Figure 3 The level indicator 2 includes a battery 250, which is disposed in the receiving cavity 110 and electrically connected to the circuit board 210.

[0065] In some embodiments, the battery 250 may be a button cell battery, which is small in size and can be easily placed in the receiving cavity 110 enclosed by the cylindrical sleeve 122.

[0066] Please refer to Figure 6 The horizontal sensor plate 230 is mounted on the circuit board 210.

[0067] Please refer to Figure 4 and Figure 5 The inner ring of the support ring 240 is provided with a mounting plate 241, and both the mounting plate 241 and the ring wall of the support ring 240 are provided with mounting holes.

[0068] This design allows for better fixation of the end of the light guide tube 222.

[0069] Please refer to Figure 10 The present invention also provides a sight with a horizontal indication function, comprising: The sight body 1 has a receiving cavity 110 on its side wall; A differentiation line lens, the differentiation line lens including a lens 310 and a fluorescent reflective graduation line layer 320 connecting the lens 310; A horizontal indicator 2 includes a circuit board 210 disposed in the receiving cavity 110, a colored dot-shaped indicator light source 220 electrically connected to the circuit board 210, and a horizontal sensor 230 electrically connected to the circuit board 210. The receiving cavity 110 communicates with the inner cavity of the lens tube 120 of the sight body 1, and the circuit board 210 is disposed in the receiving cavity 110. At least two colored dot-shaped indicator light sources 220 are disposed in the inner cavity of the lens tube 120 of the sight body 1 and are arranged against the tube wall of the lens tube 120. The light emission point of the colored dot-shaped indicator light source 220 is located between the eyepiece 130 and the zoom system 140 of the sight body 1, and the light source of the colored dot-shaped indicator light source 220 is directed towards the dividing line lens. The circuit board 210 controls one or more of the colored dot-shaped indicator light sources 220 to operate and emit light according to the data collected by the horizontal sensor 230.

[0070] The fluorescent reflective scale layer 320 itself is a differentiation line pattern, providing users with the function of differentiation lines themselves, but the differentiation lines are made of fluorescent material.

[0071] Example 8 When the horizontal sensor 230 collects information about the leveled state of the sight body, the circuit board 210 controls at least two colored dot indicator lights 220 to stop working and emit light.

[0072] When the horizontal sensor 230 collects information about the sight body tilting to the left, the circuit board 210 controls a colored dot-shaped indicator light source 220 on the left to emit light. After the light shines on the fluorescent reflective scale layer 320, the light reflected by the fluorescent reflective scale layer 320 on the left is presented to the user's eyes, indicating to the user that the sight body is tilted to the left.

[0073] When the horizontal sensor 230 collects information about the sight body tilting to the right, the circuit board 210 controls a colored dot-shaped indicator light source 220 on the right to emit light. After the light shines on the fluorescent reflective scale layer 320, the light reflected by the fluorescent reflective scale layer 320 on the right is presented to the user's eyes, indicating to the user that the sight body is tilted to the right.

[0074] The left and right portions of the fluorescent reflective scale layer 320 reflect different colors when illuminated. The colored dot-shaped indicator light source 220 emits white light.

[0075] The present invention also provides a horizontal indication method for a sight with a horizontal indication function based on the foregoing, comprising the following steps: When the attitude data collected by the horizontal sensor 230 indicates a rightward tilt, the circuit board 210 controls the colored dot indicator light source 220 to light up the first color. When the attitude data collected by the horizontal sensor 230 indicates a leftward tilt, the circuit board 210 controls the colored dot indicator light source 220 to light up a second color. When the attitude data collected by the horizontal sensor 230 indicates that the object is placed horizontally, the circuit board 210 controls the colored dot indicator light source 220 to light up a third color.

[0076] In some embodiments, the first color is red, the second color is blue, and the third color is green.

[0077] Furthermore, when the number of the colored dot-shaped indicator light sources 220 is multiple and disposed within the inner cavity of the scope tube 120 of the sight body 1: When the attitude data collected by the horizontal sensor 230 is tilted to the right, the colored dot indicator light source 220 near the right side of the control part of the circuit board 210 lights up in the first color; the greater the tilt to the right of the attitude data collected by the horizontal sensor 230, the more colored dot indicator light sources 220 that light up in the first color. In some embodiments, when the attitude data collected by the horizontal sensor 230 indicates a rightward tilt of more than 20°, all colored dot indicator lights 220 illuminate in the first color; when the attitude data collected by the horizontal sensor 230 indicates a rightward tilt of approximately 10°, a typical number of colored dot indicator lights 220 illuminate in the first color.

[0078] When the attitude data collected by the horizontal sensor 230 is tilted to the left, the colored dot indicator light 220 near the left side of the control part of the circuit board 210 lights up with a second color; the greater the tilt to the left the attitude data collected by the horizontal sensor 230 is, the more colored dot indicator light 220 lights up with the second color. When the attitude data collected by the horizontal sensor 230 indicates that the object is placed horizontally, the circuit board 210 controls all the colored dot indicator light sources 220 to light up in the third color.

[0079] Using the above method, users can quickly learn the relationship between the color of the colored dot indicator light 220 and the tilt angle of the sight body 1 and the shooting equipment without a high learning cost.
