Description

Technical Field

[0001] This utility model pertains to measuring instruments, specifically a rangefinder for measuring length. Background Technology

[0002] Rangefinders are used to measure distances. To facilitate reading, rangefinders are equipped with a display screen to show the measured data. However, due to the diverse measurement scenarios, rangefinders often change various orientations during measurement, and the display screen also changes angle and orientation accordingly. Most existing rangefinders display measured information (such as numbers) in a fixed manner relative to the screen. When the orientation of the information (such as numbers) is not conducive to visual reading, it creates reading difficulties for the user. Furthermore, during measurement, users often lean the rangefinder against certain parts of the body, which can cause impacts to the rangefinder, damaging its structure and waterproof performance. Utility Model Content

[0003] This invention addresses the drawback of existing rangefinders where the information measured is displayed in a fixed manner relative to the screen, causing visual reading difficulties and hindering user reading. It provides a rangefinder where the measured information can be rotated according to the rangefinder's orientation, thus facilitating visual reading of the measured information.

[0004] To achieve the above objectives, the rangefinder of this utility model includes a housing, an electronic measuring unit, a display screen, and control buttons. The electronic measuring unit is located inside the housing and measures through a sealed window of the housing. The display screen and control buttons are exposed on the surface of the housing. The feature is that a gyroscope for detecting the attitude of the rangefinder is installed inside the housing. When the attitude of the rangefinder changes by a set angle, the interface of the display screen flips accordingly to facilitate visual reading.

[0005] Accordingly, when the rangefinder changes its attitude during measurement, the gyroscope detects the rangefinder's attitude, and when the rangefinder's attitude changes by a set angle, the display screen flips accordingly for visual reading. Therefore, no matter how the rangefinder's attitude changes during measurement, the gyroscope's detection of the rangefinder's attitude will always cause the display screen to flip accordingly for visual reading.

[0006] Preferably, the display screen's interface is set to rotate 90° each time. This facilitates the display of information on a rectangular screen and also allows for a rectangular shape design of the rangefinder, enabling it to be positioned and maintained during measurement.

[0007] Preferably, the maximum value of the set angle is 90±10°. That is, when the rangefinder flips, the display screen will flip accordingly within a range of 90±10° to facilitate visual reading. The specific angle at which the display screen will flip depends on the orientation of the rangefinder.

[0008] Preferably, when the rangefinder's posture changes by a set angle—upright, tilted to the right, upside down, tilted to the left, or any in between—the display screen rotates accordingly for visual reading. This achieves the goal of rotating the display screen as the rangefinder rotates within a vertical plane for easy visual reading.

[0009] Preferably, the control buttons include a flip button, configured so that pressing the flip button once flips the display screen by 90°. Accordingly, pressing the flip button once as needed flips the display screen by 90°, which is suitable not only for flipping the rangefinder in a vertical plane, but also for flipping the display screen when the rangefinder rotates in a horizontal plane. This is because, for the latter case, since the gyroscope is used to detect the rangefinder's vertical rotation, it cannot detect its horizontal rotation. Flipping the display screen by pressing the flip button provides the user with greater convenience in reading information.

[0010] Preferably, the display screen interface includes an electronic bubble indicating the horizontal position. The electronic bubble determines the rangefinder's orientation, whether it is horizontal, vertical, or tilted at a specific angle. Taking the illustrated rangefinder as an example, it is a hexahedron with each face serving as a positioning surface. In actual measurement, if the object being measured is vertical, the rangefinder should be horizontal to obtain an accurate distance; conversely, if the object is horizontal, the rangefinder should be vertical to obtain an accurate distance. In other embodiments, the positioning surface of the rangefinder can be an inclined plane, allowing for the measurement of angles.

[0011] Preferably, the housing includes a box body and a lid that are fastened together. The fastening portions of the box body and the lid are provided with annular grooves and annular ribs, respectively. A sealing ring is located within the annular groove, and the annular ribs press the sealing ring tightly within the annular groove. This ensures a seal and achieves an IP65 protection rating.

[0012] Preferably, the housing includes an adhesive coating covering the surfaces of the box and the lid. This serves to cushion impacts and ensure that the strength and sealing of the housing are not compromised when subjected to an impact.

[0013] Preferably, the rangefinder is equipped with a charging interface for charging the power supply. The charging interface is exposed through the side wall of the housing, and the charging interface is sealed to the side wall of the housing. This ensures a tight seal and achieves an IP65 protection rating.

[0014] Preferably, the sealing window is located on the side wall of the housing, and a transparent cover is sealed inside the sealing window. This ensures a tight seal and achieves an IP65 protection rating.

[0015] This invention utilizes a gyroscope housed within the casing to detect the attitude of a rangefinder. When the rangefinder's attitude changes by a set angle, the display screen flips accordingly for visual reading. Therefore, during measurement, regardless of how the rangefinder's attitude changes, the gyroscope's detection of the attitude always causes the display screen to flip for visual reading.

[0016] The housing of this utility model includes a box body and a lid that are fastened together. The fastening parts of the box body and the lid are provided with annular grooves and annular ribs respectively. A sealing ring is located in the annular groove, and the annular ribs squeeze the sealing ring tightly within the annular groove. This ensures a seal and achieves an IP65 protection rating. Furthermore, the housing includes an adhesive coating on the surfaces of the box body and the lid to cushion impacts and ensure that the strength and sealing performance of the housing are not damaged when subjected to impact.

[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0046] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this utility model are intended to cover non-exclusive inclusion, such as a method or product that includes a series of technical features, not limited to those technical features explicitly listed, but also including other technical features that may be included in the method or product but not explicitly listed.

[0047] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," "right," "front," and "rear," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Among them, "upper" and "lower," "left" and "right," and "front" and "rear" are opposite directions.

[0048] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0049] like Figure 1-6 , Figure 13 , Figure 14-15 As shown, the rangefinder includes a housing 100, an electronic measuring unit 200, a display screen 300, and control buttons 400. The electronic measuring unit 200 is located inside the housing and measures through a sealed window 111 of the housing. The display screen 300 and control buttons 400 are exposed on the surface of the housing 100. Furthermore, a gyroscope 500 is disposed inside the housing 100 to detect the attitude of the rangefinder. When the attitude of the rangefinder changes by a set angle, the interface 301 of the display screen (e.g., numerical values) flips accordingly for visual reading. Therefore, when the rangefinder changes attitude during measurement, the gyroscope detects the attitude of the rangefinder, and when the attitude of the rangefinder changes by a set angle, the interface of the display screen flips accordingly for visual reading. Thus, regardless of how the attitude of the rangefinder changes during measurement, the gyroscope detects the attitude of the rangefinder, and the interface of the display screen always flips accordingly for visual reading.

[0050] Depending on their preferences and usage habits, users can disable the interface rotation function and adjust the screen brightness via control button 400.

[0051] The illustrated rangefinder has a display screen that rotates 90° at a time. This is advantageous for displaying information on a rectangular screen and also allows for a rectangular shape to facilitate positioning and maintaining the rangefinder's orientation during measurement.

[0052] The illustrated rangefinder has maximum set angles A1, A2, A3, and A4 of 90±10°. This means that when the rangefinder rotates within a 90±10° range, the display screen will rotate accordingly for easier visual reading. The specific angle at which the display screen rotates depends on the rangefinder's orientation. See also... Figure 12 When the longitudinal axis of the rangefinder (the axis extending from its rear end to its front end) is located at any of the four positions P1, P2, P3, or P4, the display screen will flip accordingly. In the diagram, using the horizontal line L (horizontal plane) and the vertical line V (vertical plane) as references, the offset angle α of the rangefinder's axis from the horizontal line (horizontal plane) or the vertical line (vertical plane) reaches the four positions P1, P2, P3, and P4. In the illustrated structure, α = 45°; in other embodiments, α can be greater than or less than 45°. Figure 11 Taking the vertical axis shown in the image as tilted to the right, close to position P1, as an example, the information displayed on the screen at this time is relative to... Figure 7 The state shown has rotated 90° counterclockwise and is in contact with... Figure 8 If the displayed state is the same, then rotate the rangefinder clockwise by approximately 90° to make the information on the display screen rotate counterclockwise by 90° until it matches the previous state. Figure 9 The state shown is the same. Conversely, if the longitudinal axis of the rangefinder is rotated counterclockwise by a small angle from position P1, the display screen will rotate clockwise accordingly. Figure 7 The state shown is as follows. When the longitudinal axis of the rangefinder is between two adjacent positions among the four positions P1, P2, P3, and P4, the display screen interface does not rotate with the rotation of the rangefinder. The different interfaces on the display screen are customized according to the actual display orientation to optimize the display layout and size.

[0053] The diagram shows a rangefinder; the rangefinder's attitude is... Figure 3 and Figure 7 As shown, upright, Figure 4 and Figure 8 The right tilt is shown. Figure 5 and Figure 9 As shown, upside down, Figure 6 and Figure 10 When the left tilt and intermediate tilt angles change by a set angle, the display screen flips accordingly for visual reading. This achieves the goal of making the display screen flip as the rangefinder rotates within a vertical plane (perpendicular to the z-axis) for easy visual reading. Figure 3-6 This flip is shown.

[0054] The illustrated rangefinder includes a control button 400, which includes a flip button 401. Pressing the flip button once rotates the display screen by 90°. Therefore, pressing the flip button once as needed rotates the display screen by 90°. This is suitable not only for rangefinders rotating in a vertical plane by pressing the flip button to rotate the display screen accordingly, but also for rangefinders used in situations such as... Figure 1-2 As shown, when rotating in the horizontal plane (rotation about the z-axis), pressing the flip button flips the display screen accordingly. This is because, for the latter case, the gyroscope is used to detect the rangefinder's rotation in the vertical plane, and therefore cannot detect its rotation in the horizontal plane. Flipping the display screen by pressing the flip button provides the user with convenient access to information.

[0055] The illustrated rangefinder includes a display screen 301 with an electronic bubble 302 indicating the horizontal position. The electronic bubble determines the rangefinder's orientation, indicating whether it is horizontal, vertical, or tilted at a specific angle. Taking the illustrated rangefinder as an example, it is a hexahedron with each face serving as a positioning surface. In actual measurement, if the object being measured is vertical, the rangefinder must be horizontal to obtain an accurate distance; conversely, if the object is horizontal, the rangefinder must be vertical to obtain an accurate distance. In other embodiments, the positioning surfaces of the rangefinder can be inclined planes, allowing for the measurement of angles. The illustrated electronic bubble 302 is tubular; in other embodiments, it can be circular.

[0056] The illustrated rangefinder includes a housing 100 comprising a box 110 and a cover 120 fastened together. The fastening portions of the box 110 and cover 120 are respectively provided with an annular groove 121 and an annular rib 112. A sealing ring 130 is located within the annular groove 121, and the annular rib 112 presses the sealing ring 130 tightly within the annular groove 121. This ensures a tight seal, achieving an IP65 protection rating.

[0057] The illustrated rangefinder includes a housing 100 with an adhesive coating 140 covering the surfaces of a box body 110 and a cover 120. This coating is used to cushion impacts and ensure that the housing's strength and sealing are not compromised when subjected to an impact.

[0058] The illustrated rangefinder is equipped with a charging port 113 for charging a power source. The charging port 113 is exposed through the side wall of the housing, and a seal is maintained between the charging port and the side wall of the housing. This seal ensures an IP65 protection rating. For power safety, a temperature-controlled rechargeable lithium battery is used as the power source.

[0059] The illustrated rangefinder has a sealed window 111 located on the side wall of the housing 110, with a transparent cover 150 sealing the inside of the sealed window to ensure a tight seal.

[0060] As described above, as the rangefinder flips, the display screen flips 90° in the opposite direction when the set angle is reached, so that the user can easily read the data information.
