Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items. Furthermore, technical features involved in the different embodiments of this invention described below may be combined with each other as long as they do not conflict with each other.

[0019] The ranging devices provided by related technologies are typically laser ranging devices. These devices measure distance based on laser ranging principles and can meet basic ranging needs. However, considering the diverse range of measurement scenarios, such as curved surface measurement, boundaryless measurement, and horizontal angle verification, laser ranging devices cannot simultaneously handle all these tasks. Therefore, the efficiency of users in measurement work has not been effectively improved. Please refer to the following: Figure 1 , Figure 2 and Figure 3 The ranging device 100 includes a housing 200, a control module 300, a laser ranging component 400, a roller ranging component 500, and an angle measuring component 600.

[0020] The housing 200 includes a top shell 21, a side shell 22 and a bottom shell 23. The side shell 22 includes a first surface 22a and a second surface 22b disposed opposite to each other. The top shell 21 is disposed on the first surface 22a and the bottom shell 23 is disposed on the second surface 22b.

[0021] The control module 300 is housed inside the housing 200. As the control core of the ranging device 100, the control module 300 is used to process and analyze various ranging data.

[0022] A laser ranging component 400 is housed within the housing 200 and electrically connected to the control module 300. It is used to measure the distance between the ranging device 100 and the object to be measured based on a laser ranging algorithm. For example, the laser ranging component 400 emits a laser signal towards the object and receives the echo signal reflected back from the object. The control module 300 determines the distance between the ranging device 100 and the object based on the echo signal. The laser ranging algorithm can be a Time-of-Flight (TOF) algorithm, etc. The laser ranging component 400 is suitable for measurement scenarios requiring the measurement of the straight-line distance between two points.

[0023] The roller ranging component 500 is electrically connected to the control module 300. A portion of the roller ranging component 500 is located outside the housing 200, while another portion is located inside the housing 200. The roller ranging component 500 can move along objects of various shapes, such as straight lines, curves, or irregular lines. The roller ranging component 500 detects rolling parameters as it rolls on the object, allowing the control module 300 to calculate the rolling distance based on these parameters. Rolling parameters include the number of rotations of the rollers in the roller ranging component 500. The roller ranging component 500 can measure objects of any shape.

[0024] In other embodiments, the entire roller ranging assembly 500 is located outside the housing 200. For example, the roller ranging assembly 500 is connected to the housing 200 through other connectors located outside the housing 200.

[0025] An angle measuring component 600 is disposed within the housing 200 and electrically connected to the control module 300. It is used to sample the horizontal measurement data of the ranging device 100, enabling the control module 300 to determine the levelness of the ranging device 100 based on this data. Levelness is the tilt angle of a specified plane relative to a horizontal plane, where the ranging device 100 is placed. When the levelness is 0 degrees, it indicates that the specified plane is horizontal and not tilted. When the levelness is not equal to 0 degrees, it indicates that the specified plane is tilted relative to the horizontal plane. The angle measuring component 600 can verify whether the specified plane is level.

[0026] The working principle of the ranging device 100 provided in this embodiment is as follows: When a user needs to measure the distance between the ranging device 100 and the object to be measured, the user operates the ranging device, controlling the laser ranging component 400 to emit a laser signal towards the object. The object reflects the laser signal, returning it to the laser ranging component 400 as an echo signal. The laser ranging component 400 receives the echo signal. The control module 300 calculates the distance between the ranging device 100 and the object to be measured based on the laser ranging algorithm and the echo signal.

[0027] When a user needs to measure the distance between point A and point B on the same curved surface, the user operates the ranging device, controlling the roller ranging component 500 to roll from point A until it reaches point B, ending the measurement operation. The control module 300 calculates the distance from point A to point B based on the rolling parameters sampled by the roller ranging component 500.

[0028] When a user needs to detect whether the plane on which the object to be measured is located is horizontal, the user places the ranging device 100 on the plane on which the object to be measured is located, controls the angle measuring component 600 to sample the horizontal measurement data, and the control module 300 detects whether the plane on which the object to be measured is located is horizontal based on the horizontal measurement data.

[0029] The ranging device 100 provided in this application embodiment integrates the ranging function of a straight line between two points, the ranging function of a line of arbitrary shape between two points, and the horizontal verification function, so that the ranging device 100 can be applied to a variety of ranging scenarios, which is conducive to improving the user experience.

[0030] Please see Figure 4a The ranging device 100 also includes a first display element 700 and a second display element 800, both of which are electrically connected to the control module 300. The housing 200 has multiple surfaces, and the first display element 700 and the second display element 800 are located on different surfaces of the housing 200.

[0031] The first display element 700 is used to display first measurement information, which includes at least one of laser ranging information, roller ranging information, and level detection information. The laser ranging information includes distances measured based on the laser ranging component 400, the roller ranging information includes distances measured based on the roller ranging component 500, and the level detection information includes levelness measured based on the angle measuring component 600.

[0032] The second display element 800 is used to display second measurement information, which may include at least one of laser ranging information, roller ranging information, and level detection information. It is understood that the content displayed by the first display element 700 and the second display element 800 may be the same or different.

[0033] The second display element 800 and the first display element 700 can visually display the levelness. For example, the second display element 800 displays a straight line. When the levelness is 0 degrees, the straight line is horizontal. When the levelness is not 0 degrees, the straight line is tilted. When the ranging device 100 detects that the left side is higher than the right side or vice versa, one end of the straight line is raised and the other end is lowered.

[0034] For another example, see Figure 4b The second display element 800 displays horizontal detection information including a horizontality value 4b1 and a tilt pattern 4b2. The tilt pattern includes a target straight line L0 perpendicular to the first display screen and a horizontal reference (T1, T2). The target straight line L0 can be translated according to the user's adjustment of the current tilt degree of the object under test. When the target straight line is translated to the horizontal reference (T1, T2), the object under test is horizontal. For example, the tilt pattern includes a first straight line L1, a second straight line L2 and a target straight line L0. The first straight line L1 and the second straight line L2 are arranged parallel to each other on opposite sides of the second display element 800. Horizontal reference T1 and horizontal reference T2 are provided in the middle of the first straight line L1 and the second straight line L2. One end of the target straight line L0 is perpendicular to the first straight line L1 and the other end of the target straight line L0 is perpendicular to the second straight line L2. The target straight line L0 moves between the first straight line L1 and the second straight line L2 according to the tilt direction.

[0035] Please combine Figure 4b The ranging device 100 is placed on the object to be measured. When the object to be measured is placed horizontally, the angle measuring component 600 detects that the horizontality is 0.0°, and then displays 0.0° on the second display element 800. The target straight line L0 is located at the horizontal reference (T1, T2) of the first straight line L1 and the second straight line L2.

[0036] Please combine Figure 4b When the object under test is higher on the left and lower on the right, the angle measuring component 600 detects a levelness of 5.0° and displays 5.0° on the second display element 800. The target line L0 is located to the left of the horizontal reference (T1, T2). The higher the left side is, the lower the right side is, the greater the levelness value, and the further the target line L0 is from the horizontal reference (T1, T2). Optionally, within a set threshold range, the target line L0 can be translated between the leftmost end and the horizontal reference (T1, T2) or between the rightmost end and the horizontal reference (T1, T2). Once the tilt angle exceeds the threshold, the indicator line will stop directly at the corresponding end.

[0037] Please combine Figure 4bWhen the object under test is lower on the left and higher on the right, the angle measuring component 600 detects a levelness of 8.0° and displays 8.0° on the second display element 800. The target line L0 is located to the right of the horizontal reference (T1, T2). The higher the right side is, the lower the left side is, the greater the levelness value, and the further the target line L0 is from the horizontal reference (T1, T2). Optionally, within a set threshold range, the target line L0 can be translated between the rightmost end and the horizontal reference (T1, T2) or between the leftmost end and the horizontal reference (T1, T2). Once the tilt angle exceeds the threshold, the indicator line will stop directly at the corresponding end.

[0038] In some embodiments, the second measurement information further includes a distance measurement reference, which provides a measurement reference for the distance measurement of the laser ranging component 400. The laser ranging component 400 measures the straight-line distance between two points. The ranging device 100 needs to be aligned with the measurement starting point for the laser ranging component 400 to accurately measure the straight-line distance between the two points. When the user needs to operate the laser ranging component 400 to measure the straight-line distance between two points, the distance measurement reference displayed by the second display element 800 (the first display element 700 can also display the distance measurement reference simultaneously) is located on the side shell 22. Since the second display element 800 is located on the side shell 22, the user can place the bottom shell 23 of the laser ranging component 400 on the object to be measured. Once the measurement starting point is aligned with the distance measurement reference displayed on the side shell 22, the user can operate and control the laser ranging component 400 to measure the straight-line distance between the two points. This obtains an accurate and reliable straight-line distance between the two points, avoiding the problem that the first display element 700 located on the top shell 21 is parallel to the object to be measured, making it impossible to directly align the distance measurement reference with the starting point. The distance measurement reference can be a straight line or other forms of marking, such as dot markings.

[0039] The distance measurement benchmark provided in this application embodiment can assist the laser ranging component 400 in performing laser measurement, thereby obtaining a more accurate and reliable distance.

[0040] It is understood that the first display element 700 or the second display element 800 can be a non-touch display screen, an indicator light, or a touch display screen.

[0041] Please see Figure 4c When the first display element 700 is a non-touchscreen display or a touchscreen display, the circuit corresponding to the first display element 700 is as follows: Figure 4c As shown.

[0042] Please see Figure 5 When the second display element 800 is a non-touchscreen display or a touchscreen display, the circuit corresponding to the second display element 800 is as follows: Figure 5 As shown.

[0043] When the first display element 700 or the second display element 800 is a touch screen, it can also be used to display an interactive interface. This interface can respond to user input, display relevant application interfaces, and trigger the control module 300 to execute related operations. For example, the first display element 700 displays an interactive interface, including a laser ranging button, a scroll wheel ranging button, and an angle measurement button. When the user clicks the laser ranging button, the control module 300 controls the first display element 700 to display the laser ranging interface, which displays information or parameters related to the laser ranging operation. When the user clicks the scroll wheel ranging button, the control module 300 controls the first display element 700 to display the scroll wheel ranging interface, which displays information or parameters related to the scroll wheel ranging operation. When the user clicks the angle measurement button, the control module 300 controls the first display element 700 to display the angle measurement interface, which displays information or parameters related to the angle measurement operation.

[0044] In some embodiments, the first display element 700 is a touch screen and the second display element 800 is a non-touch screen. This allows the ranging device 100 to be controlled and its measurement status to be viewed through the first display element 700, while the second display element 800 is only used to view the measurement status of the ranging device 100. This reduces production costs and allows users to view the measurement status of the ranging device 100 from multiple angles, making it easier for users to operate.

[0045] In some embodiments, the display area of ​​the second display element 800 is smaller than that of the first display element 700. The first display element 700 can be used as the main screen of the ranging device 100, and the second display element 800 can be used as the secondary screen of the ranging device 100. The first display element 700, with its larger display area, can display more measurement information and receive various user input operations, which is beneficial for users to input quickly. The second display element 800, with its smaller display area, can display more granular measurement information to assist users in making accurate and reliable measurements. For example, the second display element 800 displays the ranging measurement reference. Therefore, in this embodiment, the first display element 700 and the second display element 800, which are of different sizes, are configured to display measurement information according to their primary and secondary roles. This is beneficial for users to understand the measurement situation in a timely manner and can also reduce hardware costs.

[0046] The first display element 700, the second display element 800, and the laser ranging component 400 are located on different surfaces of the housing 200, and the surfaces are adjacent to each other. This arrangement allows the user to easily view the laser status of the laser ranging component 400 while operating the first display element 700 or the second display element 800, or to view the current measurement information through the first display element 700 or the second display element 800.

[0047] like Figure 3 As shown, the first display element 700 is disposed on the side of the top shell 21 that is away from the bottom shell 23. The side of the top shell 21 that is away from the bottom shell 23 is the front of the measuring device 100. The first display element 700 with a larger display area is disposed on the front of the measuring device 100, which is beneficial for displaying more measurement information or parameters to the user, and also makes it convenient for the user to control the measuring device 100 through the first display element 700.

[0048] like Figure 3 As shown, the side shell 22 includes a first side surface 22c and a second side surface 22d disposed opposite to each other. The first side surface 22c is connected between a first side of a first surface 22a and a first side of a second surface 22b, and the second side surface 22d is connected between a second side of a first surface 22a and a second side of a second surface 22b. The first side of the first surface 22a is opposite to the second side of the first surface 22a, and the first side of the second surface 22b is opposite to the second side of the second surface 22b. A second display element 800 is disposed on the first side surface 22c of the side shell 22.

[0049] Please see Figure 6a The ranging device 100 also includes a button assembly 91, which is disposed within the housing 200 and electrically connected to the control module 300. Please refer to... Figure 3 The button assembly 91 is located on the side of the top shell 21 facing away from the bottom shell 23 and is parallel to the first display element 700. The button assembly 91 is also electrically connected to the control module 300. The button assembly 91 is used to respond to user input button operations and trigger the control module 300 to perform related operations.

[0050] like Figure 3 As shown, the button assembly 91 includes a button cover 911 and a button body 912, with the button cover covering the button body 912. The button cover 911 is made of plastic, and the button body 912 is made of silicone.

The decorative ring 92 is coaxially mounted on the button through-hole 21a with the button assembly 91. The decorative ring 92 is used to display decorative patterns and improve the aesthetics of the measuring device 100. The decorative ring 92 can be made of a transparent material.

[0052] Please combine Figure 3 The ranging device 100 also includes an O-type tape 93, a light guide panel 94, and a PCB circuit board 95. The PCB circuit board 95 is equipped with a light assembly 96. The O-type tape 93, the light guide panel 94, the decorative ring 92, and the button assembly 91 are all coaxially mounted on the button through hole 21a. The O-type tape 93 is placed between the light guide panel 94 and the top shell 21 to fix the light guide panel 94 on the side of the top shell 21 facing the bottom shell 23.

[0053] Please see Figure 6b The lighting component 96 is electrically connected to the control module 300 and is used to generate light under the control of the control module 300. Figure 6b As shown, the lighting assembly 96 includes a MOSFET Q12, a resistor R114, and various LEDs. The control module 300 sends a high level to the MOSFET Q12, which then turns on, and each LED emits light at a voltage of 3.3V.

[0054] The light guide panel 94 is used to transmit the light generated by the light assembly 96 to the decorative ring 92, which generates light around the button cover 911, thus improving the aesthetics of the measuring device 100.

[0055] Please combine Figure 3 The ranging device 100 also includes a push plate 97 and a slide key 98. The push plate 97 is disposed on the first side 22c of the side shell 22 and is parallel to the second display element 800. The slide key 98 is disposed on the push plate 97, and the user can move the push plate 97 back and forth by sliding the slide key 98.

[0056] Please see Figure 7 The laser ranging component 500 includes a transmitting component 51 and a receiving component 52. The transmitting component 51 and the receiving component 52 are arranged side by side on the housing 200 and are both electrically connected to the control module 300.

[0073] The roller control circuit board 513 is located between the roller lower cover 516 and the bottom shell 23.

[0074] The operating principle of the roller ranging module 51 is as follows: The laser positioning module 52 projects a measurement start mark towards the measurement start point.
