Description

Technical Field

[0001] This utility model relates to the field of distance measuring tools, specifically to a distance measuring device. Background Technology

[0002] Measuring tapes and laser rangefinders are common distance measuring tools used in construction, interior decoration, traffic accident handling, and other fields. Current measuring tapes require the ends of the tape and the measuring tip to be horizontally aligned with the initial and final ends of the object being measured. This necessitates the use of hands or other auxiliary devices to maintain contact between the tape and the object. In certain situations, ordinary measuring tapes are inconvenient to operate and have low measurement accuracy. For example, their practicality is limited in hazardous areas.

[0003] For example, in the construction industry, measuring tapes are frequently used to measure the length of horizontal objects at height or the distance to a vertical reference point. Because the measuring tape has no fixed attachment point, the start or end point of the measurement must be determined by the person's own gaze from a distance. Therefore, the measurement values ​​have significant errors and poor accuracy, which can negatively impact subsequent construction work. To obtain more accurate measurements at height, surveyors need to erect scaffolding or ladders to climb to a higher position and attach the tape to the object being measured. If the object is long, two or more workers may need to climb to complete the measurement, which is cumbersome, labor-intensive, and carries a significant risk of fall.

[0004] Furthermore, due to the limited length of the measuring tape, its application is restricted by the tape's length, resulting in a limited measuring range. It can only be used in confined spaces, not in larger ones. The measuring range of ordinary measuring tapes is generally around 5 meters, 7.5 meters, or 10 meters; some specially designed measuring tapes can even reach 15 meters or 20 meters. However, the larger the measuring range, the larger the tape, making it inconvenient for measuring personnel to carry and use.

[0005] While existing laser rangefinders offer high measurement accuracy, they are bulky, expensive, and inconvenient to carry and use. Some portable laser rangefinders, though small and easy to carry, suffer significant wear and tear on the laser source's emitting surface and the light-receiving surface of the photosensitive device after prolonged use, affecting light feedback sensitivity and ranging accuracy. Furthermore, laser rangefinders exhibit large errors in short-distance measurements, limiting their application in fields such as interior decoration and hindering large-scale deployment. Utility Model Content

[0006] The purpose of this utility model is to provide a distance measuring device that solves the technical problems of existing measuring tapes in certain situations, such as inconvenience in operation, low measurement accuracy, and inconvenience in carrying.

[0007] To solve the above-mentioned technical problems, this utility model provides a ranging device, including...

[0016] Furthermore, the display device is configured to display working information in the current working mode.

[0017] Furthermore, the ranging device also includes a sensing component configured to detect the measured values ​​of the measuring tape structure.

[0018] Furthermore, the movable grid and the fixed grid are arranged opposite to each other. The fixed grid can rotate with the measuring tape wheel of the measuring tape structure. The movable grid and the fixed grid are configured such that when the movable grid rotates, the capacitance value between the movable grid and the fixed grid changes. The change in capacitance value is mapped to the scale of the measuring tape structure to obtain the measurement value of the measuring tape structure.

[0019] Furthermore, when the measuring tape of the measuring tape structure is pulled out, the ranging device enters the measuring tape measurement mode.

[0020] Furthermore, the display device is configured to automatically display an animation of entering the measuring tape measurement mode after the measuring tape structure is pulled out.

[0021] Furthermore, the ranging device also includes a locking mechanism configured to compress the tape movement of the measuring tape structure.

[0022] Furthermore, the locking mechanism includes a locking key and a pressure block, wherein the locking key is configured to move the pressure block together.

[0023] Furthermore, one end of the locking key is connected to one end of the pressure block, and the other end of the pressure block is configured to prevent the movement of the ruler. When the locking key is pressed, it drives the pressure block to move.

[0024] Furthermore, the connection between the locking key and the pressure block is pivotally connected to the measuring tape structure.

[0025] Furthermore, the connection between the locking key and the pressure block is pivotally connected to the housing.

[0026] Furthermore, the locking mechanism includes an elastic element configured to apply a spring force to the pressure block, causing the pressure block to press against the tape measure mechanism.

[0027] Furthermore, one end of the pressure block is pivotally connected to the measuring tape structure, the other end of the pressure block is configured to contact the measuring tape, and one end of the locking key contacts the pressure block under external force and pushes the pressure block to move away from the measuring tape.

[0028] Furthermore, the pressure block has an arc that matches the tape measure structure, and the locking key is configured to slide circumferentially along the outer casing to drive the pressure block to move circumferentially along the tape measure structure, so that one end of the pressure block away from the locking key contacts and locks the tape.

[0029] The advantages of this invention are that it provides a distance measuring device that effectively improves upon existing laser rangefinders, extending their service life and maintaining their light feedback sensitivity and measurement accuracy even after prolonged use. This invention combines a measuring tape with a laser rangefinder, offering both short-distance and long-distance measurement capabilities. It is characterized by simple operation, portability, low cost, and high measurement accuracy, making it suitable for large-scale application in fields such as construction, interior decoration, and hazardous area measurement. By modularizing the measuring tape, it can be easily installed in a single housing with the laser rangefinder, reducing production costs and improving assembly efficiency. The invention incorporates a sensing component that detects the length of the measuring tape's movement, thereby detecting the measured value and achieving higher accuracy compared to manual measurement.

[0035] The entire contents of U.S. Patent Application No. 18 / 133,823, US2023 / 029677 A1, are incorporated herein by reference.

[0036] Example 1

[0037] like Figure 1-11 As shown, Embodiment 1 provides a ranging device with laser ranging function and tape measure ranging function. The laser module 110 and the tape measure structure 120 are installed in the same housing 100, wherein the tape measure structure 120 is assembled independently as a whole in the housing 100.

[0038] like Figure 3 and 4 As shown, the ranging device provided in this embodiment includes a housing 100, and an accommodating space 101 is formed inside the housing 100. A laser module 110, a battery 130, a display device 133, a first circuit board 132, and a measuring tape structure 120 are disposed in the accommodating space 101.

[0039] Laser module 110 can generate laser light, capture the laser light reflected from the object under test, and convert it into an electrical signal. Laser module 110 can be a laser device known in the prior art for distance measurement; the content regarding a laser distance measuring device in Embodiment 1 of US Patent Application US2023 / 029677 A1 is incorporated into this embodiment. Figure 7-9 As shown, the laser module 110 includes a laser generating device 111, a photoelectric conversion device 112, and a second circuit board 113. The laser generating device 111 is preferably a laser tube, i.e., a glass-sealed CO2 laser, but is not limited to a laser tube; it can also be any other device capable of generating a laser beam. The photoelectric conversion device 112 is preferably a photoelectric sensor, but is not limited to a photoelectric sensor; it can also be any other device capable of capturing light and converting light signals into electrical signals. The laser generating device 111 and the photoelectric conversion device 112 can be arranged side-by-side or vertically. In this embodiment, the laser generating device 111 and the photoelectric conversion device 112 are integrated. The laser generating device 111 includes a light-emitting surface 114, and the photoelectric conversion device 112 includes a light-receiving surface 115. The light-emitting surface 114 is disposed next to the light-receiving surface 115 and adjacent to it; they can be arranged side-by-side or vertically. The second circuit board 113 can be integrated with the first circuit board 112 as a whole, or it can be set separately. In this embodiment, the second circuit board 113 is set separately and integrated into the laser module 110. The second circuit board 113 is provided with at least one processor 116, which is connected to the laser generator 111 and used to control the laser generator 111 to operate normally. The processor 116 is also connected to the photoelectric conversion device 112 to acquire feedback electrical signals and calculate the distance between the object under test and the ranging device described in this embodiment. Optionally, the second circuit board 113 may also be provided with a memory 117, which is connected to the processor 116. It should be understood that after the second circuit board 113 and the first circuit board 132 are integrated into one unit, they can share a single processor 116 and memory 117.

[0040] In some embodiments, the emitting surface 114 of the laser generator 111 and the receiving surface 115 of the photoelectric conversion device 112 can both be disposed on the outer surface of the housing 100. The laser generator 111 emits a laser beam from the emitting surface 114 as a measurement beam; the photoelectric conversion device 112 captures external reflected light through the receiving surface 115. If the emitting surface 114 and the receiving surface 115 are disposed on the outer surface of the housing 100, they are easily subjected to wear during carrying, use, and storage. After long-term use, due to significant wear, the light feedback sensitivity and measurement accuracy of the rangefinder will be reduced, thus shortening its service life. Therefore, this embodiment also provides the following technical solution. Figure 2 and Figure 5 As shown, the outer casing 100 is provided with a laser beam emitting port 103 and a light receiving port 104. The laser beam emitting port 103 faces the light-emitting surface 114, and the light receiving port 104 faces the light-receiving surface 115. Since the light-emitting surface 114 and the light-receiving surface 115 are adjacent to each other, the laser beam emitting port 103 and the light receiving port 104 are also arranged adjacent to each other. In this embodiment, both the laser beam emitting port 103 and the light receiving port 104 are provided on the side of the outer casing 100 along the radial direction of the measuring tape structure 120. In some embodiments, the outer casing 100 is provided with a first opening 102, and a removable cover 105 is provided at the first opening 102, on which the laser beam emitting port 103 and the light receiving port 104 are disposed. When the cover 105 is closed at the first opening 102, the laser beam emitting port 103 faces the light-emitting surface 114, and the light receiving port 104 faces the light-receiving surface 115. The light-emitting surface 114 and the light-receiving surface 115 are entirely located inside the housing, rather than on the surface, which protects them from wear and reduces the impact of dust and moisture in the surrounding environment on electronic components. Without affecting the normal operation of the laser generator 111 and the photoelectric conversion device 112, this design further extends the service life of the light-emitting surface 114 and the light-receiving surface 115, ensuring the light feedback sensitivity and measurement accuracy of the ranging device.

[0041] In this embodiment, the center point of the emitting surface 114 and the center point of the receiving surface 115 are on the same straight line. The closer the distance between the emitting surface 114 and the receiving surface 115, the closer the distance between the light receiving aperture 104 and the laser beam emitting port 103, and the smaller the error. Theoretically, if the center points of the emitting surface 114 and the receiving surface 115 completely coincide, the error is minimized, but this is currently difficult to achieve. Generally, the area of ​​the receiving surface 115 is 3 to 10 times the area of ​​the emitting surface 114. Since the laser beam can maintain a straight path when emitted, after reflection from the surface of the object under test, if the object under test is not a mirror with excellent reflectivity, even if the laser beam can illuminate the object perpendicularly to its surface, it is difficult to guarantee the intensity and quantity of light that returns to the vicinity of the emitting surface 114 after reflection. Therefore, appropriately increasing the area of ​​the receiving surface 115 can further improve the measurement accuracy and feedback sensitivity. The laser beam emitting port 103 is slightly larger than the emitting surface 114, and the light receiving port 104 is slightly larger than the light receiving surface 115. Since the area of ​​the light receiving surface 115 is generally 3 to 10 times the area of ​​the emitting surface 114, the area of ​​the light receiving port 104 is also 3 to 10 times the area of ​​the laser beam emitting port 103.

[0042] See Figure 3The measuring tape structure 120 is a single unit, integrating the measuring tape and its related components into a single, independent module, which is then assembled. This independent module can be manufactured and transported separately. The use of an independent module in the measuring tape structure 120 allows for rapid assembly of the distance measuring device. The description of the measuring tape in Embodiments 2 and 6 of US Application US2023 / 029677 A1 is incorporated herein by reference. Figure 4 and Figure 10 As shown, the measuring tape structure 120 includes a measuring tape housing 121, a measuring tape wheel 122, and a measuring tape 123. The measuring tape housing 121 has an internal cavity, and the measuring tape wheel 122 is rotatably disposed within the cavity. The measuring tape 123 is wholly or partially wound around the measuring tape wheel 122. A first tape outlet 124 is provided on the side of the measuring tape housing 121, and the measuring tape end 125 of the measuring tape 123 extends out of the measuring tape housing 121 from the first tape outlet 124. A second tape outlet 106 is provided on the outer casing 100 opposite the first tape outlet 124, and the measuring tape end 125 of the measuring tape 123 passes through the second tape outlet 106 and extends out of the outer casing 100.

[0043] See Figure 3 The outer casing 100 may include a first casing 107 and a second casing 108. In some embodiments, a receiving space 101 is formed within the first casing 107, and all accessories are installed within the receiving space 101 of the first casing 107. Then, the second casing 108 is closed over the opening of the receiving space 101 of the first casing 107, thereby forming the outer casing 100. By using the first casing 107 to house the accessories and the second casing 108 as a cover, the product size can be reduced, making the product more compact.

[0044] The measuring tape structure 120 is installed inside the housing 100. The laser module 110, battery 130, circuit board, and display device 133 are disposed in the space between the measuring tape structure 120 and the inner side of the housing 100, so as to make the most of the space inside the housing 100 and reduce the overall size of the ranging device. In some embodiments, such as Figure 3 and 4 As shown, the laser module 110 is located at the radial edge (i.e., the radial direction of the measuring tape wheel 122) of the measuring tape structure 120. The battery 130 is located at the radial edge of the measuring tape structure 120, and the length direction of the battery 130 is approximately perpendicular to the length direction of the laser module 110. The battery 130 can be a dry cell battery or a rechargeable battery; the battery 130 shown is a rechargeable battery, and a charging port 131 is provided on the side of the housing 100. The first circuit board 132 can be located at the end face of the measuring tape structure 120 facing the second housing 108 along its axial direction and is fixed to the measuring tape structure 120.

[0045] The ranging device also includes a locking mechanism 140 for locking or unlocking the ruler 123. In some embodiments, such as Figure 4 and 11 As shown, the locking mechanism 140 includes a button 141 and a pressure block 142. One end of the button 141 is connected to the pressure block 142, and the button 141 can drive the pressure block 142 to move together. Preferably, the button 141 and the pressure block 142 are an integral part. The pressure block 142 is disposed at the opening on the radial edge of the tape measure housing 121 (this opening can be the same as the first tape outlet 124). Under the action of external force, the pressure block 142 can press the tape measure wheel 122, so that the tape measure wheel 122 stops rotating, thereby stopping the tape 123 from rotating. Preferably, it presses the radial contour of the tape measure wheel 122. The pressure block 142 is connected to a rotating shaft 143 disposed on the tape measure housing 121, and the pressure block 142 can rotate through the rotating shaft 143. A first elastic element 144 is disposed between the pressure block 142 and the outer casing 100. The first elastic element 144 applies elastic force to the pressure block 142 to cause the pressure block 142 to press against the tape measure wheel 122. When button 141 is pressed, button 141 rotates around pivot 143 toward tape measure structure 120, causing pressure block 142 to rotate away from tape 123, thus releasing pressure block 142 from tape measure wheel 122. When button 141 is released, the elastic force applied by first elastic element 144 on pressure block 142 causes pressure block 142 to move toward tape measure wheel 122, and drives button 141 toward housing 100, thus resetting button 141; preferably, a second elastic element 145 is provided at button 141. Figure 6 As shown, the second elastic element 145 can assist in the reset of the button 141. Preferably, the second elastic element 145 can be a compression spring. Of course, those skilled in the art will understand that the second elastic element 145 alone applies a force to the pressure block 142 to press against the measuring tape wheel 122. The first elastic element 144 and the second elastic element 145 can be springs, but it should be understood that the first elastic element 144 and the second elastic element 145 are not limited to springs, but can also be other forms of elastic elements that can provide elastic force, such as spring sheets. The button 141 and the pressure block 142 can be integrally formed. In this embodiment, the pivot 143 of the button 141 is provided on the measuring tape housing 121, which is beneficial to reduce the size of the product. The locking mechanism 140 directly cooperates with the components of the measuring tape structure, reducing the assembly error of the housing and improving the consistency of product assembly.

[0046] See Figure 3 and 4A guide 150 may be provided on the inner side of the outer casing 100 near the second tape outlet 106. The guide 150 includes two opposing protrusions 151, forming a channel 152 between the two protrusions 151 for the tape 123 to pass through. A portion of the tape 123 passes through this channel 152. By providing the guide 150, the tape 123 can be supported, allowing the tape 123 to extend more smoothly from or retract into the outer casing 100.

[0047] The ranging device in this embodiment also includes a sensing component (not shown in the figure), which can acquire the value of the distance measured by the measuring tape structure 120. Embodiment 12 of US Application US2023 / 029677 A1 describes a Hall effect sensor as the sensing component for acquiring the measuring tape value, and Embodiment 13 of US Application US2023 / 029677 A1 describes a combination of an identification code and an identification code recognition component as the sensing component for acquiring the measuring tape value. These sensing components can all be applied to this embodiment. In some embodiments, photoelectric pulse technology can be used to acquire the measuring tape value and display it on a display device. For example, a photosensitive element is provided at the tape 123 to illuminate the tape 123, and a specific pattern of interval codes (such as black and white interval codes) is printed on the tape 123. The photosensitive element converts these interval codes into electrical signals, and then the processor generates corresponding values ​​based on these electrical signals and displays them on the display device. It should be understood that the sensing component 460 described in Embodiment 4 can be applied to this embodiment.

[0048] See Figure 4 The display device 133 can be disposed in the space between the laser module 110 and the side wall of the housing 100. Preferably, a second opening 109 is provided on the side wall of the housing 100, the second opening 109 is directly opposite the display device 133, and a transparent cover 134 is closed at the second opening 109 to protect the display device 133. The display device 133 can display the measurement values ​​of the laser module 110 and the measuring tape structure 120, and can also display working information such as system settings, operating mode (e.g., laser ranging mode, measuring tape mode), measurement reference, number of measurements, area, volume, trigonometric function values, and alarm information.

[0049] See Figure 1 and Figure 3The ranging device also includes an operation component 170. Through the operation component 170, in conjunction with the display device 133, the user can perform a series of operations on the ranging device, such as: selecting a working mode (e.g., laser ranging mode, tape measure ranging mode, and system setting mode), emitting a laser, setting the number of measurements, setting the measurement reference, setting the result output method (e.g., outputting area, volume, or trigonometric function values), setting the measurement unit, enabling or disabling sound, adjusting screen brightness, flipping the screen, and clearing memory. In some embodiments, the operation component 170 includes multiple buttons 171 with different functions and corresponding button caps 172. For example... Figure 3 As shown, the circuit board has three buttons 171. The first housing 107 has multiple through holes on its sidewall facing the circuit board, each through hole housing a button cap 172 corresponding to one button 171. A portion of the button cap 172 protrudes beyond the housing 100. Pressing the button cap 172 triggers the corresponding button 171. In some embodiments, the same button 171 can perform different functions depending on the duration of the press. For example, a button with a power-off function can power off the device with a two-second press and clear data with a short press. In some embodiments, the same button 171 has different functions in different operating modes. For example, a button pressed in laser ranging mode might be used to select a reference point, while in menu operation mode it might be used to turn pages.

[0050] In some embodiments, the display device 133 and the operation component 170 can be integrated, for example, by using a touch screen, to simultaneously realize operation control functions and display functions.

[0051] In this embodiment, by installing the measuring tape structure 120 as an independent module within the housing 100, the measuring tape structure 120 can be pre-manufactured before assembling the ranging device, improving the assembly efficiency of the ranging device. Furthermore, by utilizing the gap between the measuring tape structure 120 and the housing 100, accessories such as the laser module 110 and battery 130, along with the measuring tape structure 120, are rationally arranged within the housing 100, enabling the ranging device to simultaneously perform both long-distance and short-distance ranging functions. This also makes it convenient for users to carry and operate during work. The operation component 170 enables different operating modes and displays values, further facilitating operation and improving measurement accuracy.

[0052] Example 2

[0053] like Figure 12-17 As shown, Embodiment 2 provides a ranging device with laser ranging function and tape measure ranging function. The laser module 210 and the tape measure structure 220 are installed in the same housing 200, wherein the tape measure structure 220 is assembled independently as a whole in the housing 200.

[0054] like Figure 12 , 13 As shown in Figure 14, the ranging device provided in the embodiment includes a housing 200, and an accommodating space 201 is formed inside the housing 200. A laser module 210, a battery 230, a display device 233, a circuit board 232, and a measuring tape structure 220 are disposed in the accommodating space 201.

[0055] The laser module 210 can generate laser light, capture the laser light reflected from the object under test, and convert it into an electrical signal. It includes a laser generator (not shown in the figure), a photoelectric conversion device (not shown in the figure), and a second circuit board (not shown in the figure). For example... Figure 14 and 15 As shown, the laser generating device includes a light-emitting surface 214, and the photoelectric conversion device includes a light-receiving surface 215. Correspondingly, a laser beam emitting port 203 facing the light-emitting surface 214 and a light receiving port 204 facing the light-receiving surface 215 are provided on the housing 200. The laser module 210 of this embodiment can be substantially the same as the laser module of Embodiment 1, and will not be described again here.

[0056] The measuring tape structure 220 is a single unit, integrating the measuring tape and its related components into a single module, which is then assembled. This single module can be manufactured and transported separately. The measuring tape structure 220 can be the same as the measuring tape structure in Embodiment 1, and will not be described again here.

[0057] See Figure 14 The outer casing 200 may include a first casing 207 and a second casing 208. In some embodiments, a receiving space 201 is formed within the first casing 207, and all accessories are installed within the receiving space 201 of the first casing 207. Then, the second casing 208 is closed over the opening of the receiving space 201 of the first casing 207, thereby forming the outer casing 200. By using the first casing 207 to house the accessories and the second casing 208 as a cover, the product size can be reduced, making the product more compact.

[0058] The measuring tape structure 220 is installed inside the housing 200. The laser module 210, battery 230, and circuit board 232 are disposed within the space between the edge and axial end face of the measuring tape structure 220 and the inner side of the housing 200, in order to make the most of the space within the housing 200 and reduce the overall size of the ranging device. In some embodiments, such as Figure 14 and 15As shown, the laser module 210 is disposed at the axial end face of the measuring tape structure 220. A laser beam emitting port 203, facing the emitting surface 214 of the laser module 210, and a light receiving port 204, facing the light receiving surface 215 of the laser module 210, are respectively provided on the outer surface of the housing 200. The battery 230 is disposed at the axial end face of the measuring tape structure 220, and the length direction of the battery 230 is approximately parallel to the length direction of the laser module 210. The battery 230 can be a dry cell battery or a rechargeable battery; the battery 230 shown is a dry cell battery. An opening for removing or placing the battery 230 is provided on the radial side of the housing 200 along the measuring tape structure 220. The circuit board 232 is disposed at the axial end face of the measuring tape structure 220 and fixed to the measuring tape structure 220.

[0059] In this embodiment, the ranging device includes a locking mechanism 240 for tightening or loosening the measuring tape 223, which differs structurally from the locking mechanism in Embodiment 1. For example... Figure 15-17As shown, the locking mechanism 240 includes a button 241 and a pressure block 242. One end of the button 241 is a pressing end 2411, protruding outside the housing 200, and the other end contacts the pressure block 242. When the button 241 is pressed, it causes the pressure block 242 to move together. One end of the pressure block 242 is pivotally connected to the tape measure housing 221 of the tape measure structure 220 via a pivot 243, and the other end 2421 can contact the tape 223. When the button 241 is not pressed, one end of the pressure block 242 contacts the tape 223 and presses the tape 223, preventing the tape 223 from moving. When the button 241 is pressed, the button 241 moves towards the tape 223, causing the pressure block 242 to rotate relative to the tape measure housing 200, thereby releasing the tape 223 and allowing the tape 223 to move. In some embodiments, the button 241 and the pressure block 242 are located near the tape outlet 206 of the housing 200, where the tape 223 is not wound around the tape reel 222 of the tape measure structure but is laid flat, and the end 2421 of the pressure block 242 can contact the tape 223. Preferably, the tape measure housing 221 extends toward the tape outlet 206 to form an extension 224, and the pressure block 242 is pivotally connected to this extension 224. In some embodiments, the portion of the button 241 located inside the housing 200 forms two opposing protrusions 2412, with a channel 2413 between the protrusions 2412 for the tape 223 to pass through, and one end of the protrusion 2412 contacts the pressure block 242. Ears 2422 are provided on both sides of the pressure block 242, each ear 2422 contacting one of the protrusions 2412. Preferably, the surfaces of the protrusion 2412 and the ear 2422 that contact each other are inclined surfaces 2414 (inclined relative to the flat portion of the measuring tape 223). The pressure block 242 is inclined relative to the flat portion of the measuring tape 223. When the button 241 is pressed, the button 241 moves toward the measuring tape 223, and the direction of movement forms an angle with the inclined surface 2414, which is more conducive to pushing the pressure block 242 to rotate. In some embodiments, a first elastic element 244 is provided between the pressure block 242 and the outer casing 200. The first elastic element 244 applies a spring force to the pressure block 242 to cause the pressure block 242 to move toward the measuring tape 223. When the button 241 is not pressed, the spring force of the first elastic element 244 on the pressure block 242 causes the pressure block 242 to contact the measuring tape 223 and press the measuring tape 223. When the button 241 is pressed, it drives the pressure block 242 to move, which can overcome the spring force of the first elastic element 244. Preferably, the first elastic element 244 is a spring sheet, one end of which is connected to the housing 200 and the other end is connected to the pressure block 242. In some embodiments, a second elastic element 245 is provided between the button 241 and the measuring tape housing 221. One end of the second elastic element 245 is connected to the measuring tape housing 221 and the other end is connected to the button 241. The second elastic element 245 applies a spring force to the button 241 to cause the button 241 to move away from the measuring tape 223.When button 241 is not pressed, the elastic force of the second elastic element 245 causes button 241 to move away from the tape 223 and be reset. In this embodiment, the structure of button 241 and pressure block 242 makes full use of the space between tape measure structure 220 and tape outlet 206 of housing 200, which helps to reduce the size of the ranging device.

[0060] like Figure 17 As shown, this embodiment is provided with a guide member 250, which is the same as in embodiment 1.

[0061] The ranging device in this embodiment may be equipped with a sensing component (not shown in the figure). The sensing component may be any of the sensing components described in Embodiments 1 and 4, and is used to obtain the measurement value of the measuring tape structure 220.

[0062] In this embodiment, the display device 233 is disposed between the radial edge of the measuring tape structure 220 and the outer casing 200. Since the laser module 210, battery 230, etc., are all disposed at the axial end face of the measuring tape structure 220, the length direction of the display device 233 can be parallel to the axial direction of the measuring tape structure 220. The other structures and functions of the display device 233 can be the same as in Embodiment 1. It can display measurement values, as well as system settings, operating modes (e.g., laser ranging mode, measuring tape mode), measurement reference, number of measurements, area, volume, trigonometric function values, alarm information, etc.

[0063] The ranging device in this embodiment may include an operation component 270. Through the operation component 270, in conjunction with the display device 233, the user can perform a series of operations on the ranging device, such as: selecting a working mode (e.g., laser ranging mode, tape measure ranging mode, and system setting mode), emitting a laser, setting the number of measurements, setting a measurement reference, setting the result output method (e.g., outputting area, volume, or trigonometric function values), setting the measurement unit, enabling or disabling sound, adjusting screen brightness, flipping the screen, and clearing memory. The operation component 270 includes a button 271 and a corresponding button cap 272. Similar to the button in Embodiment 1, the button 271 in this embodiment may have different functions depending on the duration of the press and the current working mode, which will not be described in detail here.

[0064] In this embodiment, by installing the measuring tape structure 220 as an independent module within the housing 200, the measuring tape structure 220 can be pre-manufactured before assembling the ranging device, improving the assembly efficiency of the ranging device. This embodiment utilizes the gap between the measuring tape structure 220 and the housing 200 to rationally arrange accessories such as the laser module 210 and battery 230, along with the measuring tape structure 220, within the housing 200. This allows the ranging device to simultaneously perform both long-distance and short-distance ranging functions, while also being convenient for users to carry and operate during work. The operation component 270 enables different operating modes and displays values, further facilitating operation and improving measurement accuracy.

[0065] Example 3

[0066] like Figure 18-28 As shown, Embodiment 3 provides a ranging device with laser ranging function and tape measure ranging function. The laser module 310 and the tape measure structure 320 are installed in the same housing 300, wherein the tape measure structure 320 is assembled independently as a whole in the housing 300.

[0067] like Figure 20 , 21 As shown in Figure 22, the ranging device provided in Embodiment 3 includes a housing 300, and an accommodating space 301 is formed inside the housing 300. A laser module 310, a battery 330, a display device 333, a circuit board 332, and a measuring tape structure 320 are disposed in the accommodating space 301.

[0068] The laser module 310 can generate laser light, capture the laser light reflected from the object under test, and convert it into an electrical signal. It includes a laser generator (not shown in the figure), a photoelectric conversion device (not shown in the figure), and a second circuit board 332 (not shown in the figure). Figure 19 and 22 As shown, the laser generating device includes a light-emitting surface 314, and the photoelectric conversion device includes a light-receiving surface 315. Accordingly, a laser beam emitting port 303 facing the light-emitting surface 314 and a light receiving port 304 facing the light-receiving surface 315 are provided on the housing 300. The laser module 310 of this embodiment can be substantially the same as the laser module of Embodiment 1, and will not be described again here.

[0069] The measuring tape structure 320 is a single unit, integrating the measuring tape and its related components into a single, independent module, which is then assembled. This independent module can be manufactured and transported separately. The measuring tape structure 320 can be the same as the measuring tape structure in Embodiment 1, and will not be described again here.

[0070] like Figure 20As shown, the outer casing 300 may include a first casing 307 and a second casing 308. In some embodiments, a receiving space 301 is formed within the first casing 307, and all accessories are installed within the receiving space 301 of the first casing 307. Then, the second casing 308 is closed over the opening of the receiving space 301 of the first casing 307, thereby forming the outer casing 300. By using the first casing 307 to house the accessories and the second casing 308 as a cover, the product size can be reduced, making the product more compact.

[0071] like Figure 20 and 21 As shown, the measuring tape structure 320 is installed inside the housing 300. The laser module 310, battery 330, and circuit board 332 are disposed in the space between the edge and axial end face of the measuring tape structure 320 and the inner side of the housing 300, so as to make the most of the space inside the housing 300 and reduce the overall size of the ranging device. In some embodiments, the laser module 310 is disposed on the radial side of the measuring tape structure 320, preferably at the edge of the measuring tape structure 320 furthest from its center. At this position, the space between the measuring tape structure 320 and the housing 300 is relatively large, and the length direction of the laser module 310 can be arranged approximately perpendicular to the axial direction of the measuring tape structure 320. A laser beam emitting port 303 facing the emitting surface 314 of the laser module 310 and a light receiving port 304 facing the light receiving surface 315 of the laser module 310 are respectively provided on the outer surface of the housing 300. The battery 330 is located on the radial side of the measuring tape structure 320, and the length direction of the battery 330 is approximately perpendicular to the length direction of the laser module 310. The battery 330 can be a dry cell battery or a rechargeable battery; the battery 330 shown in the figure is a rechargeable battery, and a charging port 331 is provided on the radial side of the measuring tape structure 320 on the housing 300. The circuit board 332 is located on the axial end face of the measuring tape structure 320 and is fixed to the measuring tape structure 320.

[0072] In this embodiment, the ranging device includes a locking mechanism 340 for tightening or loosening the measuring tape 323, which differs structurally from the locking mechanisms in embodiments 1 and 2. Figure 21 , 23As shown in Figure -28, the locking mechanism 340 includes a button 341 and a pressure block 342. One end of the pressure block 342 is connected to the button 341 and can move together with the button 341. The pressure block 342 is generally arc-shaped, and its curvature is approximately the same as the curvature of the circumferential outer contour of the measuring tape structure 320. A portion of the button 341 protrudes outside the housing 300. A first opening 305 is provided on the housing 300 at the location where the button 341 is located. The button 341 can slide back and forth along the circumference of the housing 300 at the first opening 305, thereby driving the pressure block 342 to move along the circumference of the measuring tape structure 320. The end 343 of the pressure block 342 away from the button 341 faces the tape 323. When the button 341 is slid towards the tape outlet 306, the end 343 of the pressure block 342 contacts and presses the tape 323. Preferably, the end 343 of the pressure block 342 contacts the portion of the tape 323 near the tape outlet 306, and this portion of the tape 323 is not wound on the tape reel of the tape measure structure 320. In some embodiments, see... Figure 25-27 A gap 344 exists between the button 341 and the pressure block 342. A first wing 345, which can be inserted into this gap 344, is provided on the side wall of the housing 300. When the button 341 and the pressure block 342 move, the first wing 345 located in the gap 344 moves relative to the button 341. This allows the first wing 345 to provide good guidance, preventing deviations in the movement trajectories of the button 341 and the pressure block 342. Preferably, there are two first wings 345, arranged opposite each other. One is located on the first housing 307, and the first is located on the second housing 308. The two first wings 345 are inserted into the gap 344 from both sides of the width of the pressure block 342. The first wing 345 has the same curvature as the pressure block 342. In some embodiments, a second wing 346 is further provided on the side wall of the outer casing 300. The second wing 346 is located near the end of the pressure block 342. There can be two second wings 346, which are arranged opposite each other and respectively provided on the first casing 307 and the second casing 308. The pressure block 342 is provided with a boss 347 extending along its length direction. The width of the boss 347 is smaller than the overall width of the pressure block 342. The second wings 346 are located on both sides of the boss 347 in the width direction, and a channel is formed between the two second wings 346 to allow the boss 347 to pass through, thereby guiding the movement path of the pressure block 342. Each second wing 346 has a certain curvature and matches the curvature of the pressure block 342. In some embodiments, see [reference needed]. Figure 26 and 28The locking mechanism 340 also includes a locking block 348. The locking block 348 and the pressure block 342 are located on opposite sides of the thickness direction of the measuring tape 323. When the ranging device is in the position shown in the figure, the pressure block 342 contacts the measuring tape 323 from above, and the locking block 348 contacts the measuring tape 323 from below. Under the combined action of the locking block 348 and the pressure block 342, the measuring tape 323 can be pressed more firmly. In some embodiments, the locking block 348 is disposed at the second opening 309 of the housing 300, and a portion of the locking block 348 protrudes outside the housing 300. The user can operate the locking block 348 to move towards or away from the measuring tape 323. Preferably, one end of the locking block 348 is pivotally connected to the housing 300, allowing the locking block 348 to rotate, and its free end (free end 349) can then contact or disengage from the measuring tape 323. An elastic element 350 is provided at the pivot of the locking block 348. The elastic force of the elastic element 350 causes the free end 349 of the locking block 348 to rotate in the direction of the tape 323.

[0073] See Figure 21 In this embodiment, a guide member 351 is provided, which is the same as in embodiment 1.

[0074] The ranging device in this embodiment may be equipped with a sensing component, which may be any of the sensing components described in embodiments 1 and 4, for obtaining the measuring tape measurement value of the measuring tape structure 320.

[0075] In this embodiment, the display device 333 is disposed between the radial edge of the measuring tape structure 320 and the outer casing 300. The structure and function of the display device 333 can be the same as in Embodiment 1, and it can display measurement values, as well as system settings, operating modes (e.g., laser ranging mode, measuring tape mode), measurement reference, number of measurements, area, volume, trigonometric function values, alarm information, etc.

[0076] The ranging device in this embodiment may include an operation component 370. Through the operation component 370, in conjunction with the display device 333, the user can perform a series of operations on the ranging device, such as: selecting a working mode (e.g., laser ranging mode, tape measure ranging mode, and system setting mode), emitting a laser, setting the number of measurements, setting a measurement reference, setting the result output method (e.g., outputting area, volume, or trigonometric function values), setting the measurement unit, enabling or disabling sound, adjusting screen brightness, flipping the screen, and clearing memory. The operation component 370 includes a button 371 and a corresponding button cap 372. Similar to the button 371 in Embodiment 1, the button 371 in this embodiment may have different functions depending on the duration of the press and the current working mode, which will not be described in detail here.

[0077] See Figure 18 and20 This embodiment also includes an illumination component 360 for illuminating the tape 323. Preferably, the illumination component 360 is disposed within the housing 300 and near the tape outlet 306. The illumination component 360 includes an illumination element 363, an illumination button 361, and a corresponding button cap 362. When the button cap 362 is pressed, the illumination element 363 is illuminated, which can illuminate the tape 323 that has been pulled out of the housing 300 to facilitate user reading. Preferably, the illumination element 363 is disposed on a radial side of the housing 300 and above the tape outlet 306 (i.e., towards the first opening 305). The illumination element 363 may be an LED light.

[0078] In this embodiment, the measuring tape structure 320 is installed as an independent module within the housing 300. This allows for the pre-manufacturing of the measuring tape structure 320 before assembling the ranging device, improving assembly efficiency. Utilizing the gap between the measuring tape structure 320 and the housing 300, the laser module 310, battery 330, and other accessories are rationally arranged within the housing 300, enabling the ranging device to perform both long-distance and short-distance ranging functions. This also makes it convenient for users to carry and operate during work. The operation component 370 allows for different operating modes and displays values, further facilitating operation and improving measurement accuracy.

[0079] Example 4

[0080] like Figures 29-34 As shown, Embodiment 4 provides a ranging device with laser ranging function and tape measure ranging function. The laser ranging device and the tape measure structure 420 are installed in the same housing 400, wherein the tape measure structure 420 is assembled independently as a whole in the housing 400.

[0081] like Figure 30 and 31 As shown, the ranging device provided in Embodiment 4 includes a housing 400, and an accommodating space 401 is formed inside the housing 400. A laser module 410, a battery 430, a display device 433, a circuit board 432, and a measuring tape structure 420 are disposed in the accommodating space 401.

[0082] The laser module 410 can generate laser light, capture the laser light reflected from the object under test, and convert it into an electrical signal. It includes a laser generator (not shown in the figure), a photoelectric conversion device (not shown in the figure), and a second circuit board (not shown in the figure). For example... Figure 30As shown, the laser generating device includes a light-emitting surface 414, and the photoelectric conversion device includes a light-receiving surface 415. Correspondingly, a laser beam emitting port (not shown in the figure) facing the light-emitting surface 414 and a light receiving hole (not shown in the figure) facing the light-receiving surface 415 are provided on the housing 400. The laser module 410 of this embodiment can be substantially the same as the laser module of Embodiment 1, and will not be described again here.

[0083] The measuring tape structure 420 is a single unit, integrating the measuring tape and its related components into a single, independent module, which is then assembled. This independent module can be manufactured and transported separately. The measuring tape structure 420 can be the same as the measuring tape structure in Embodiment 1, and will not be described again here.

[0084] The outer casing 400 may include a first casing 407 and a second casing (not shown). In some embodiments, a receiving space 401 is formed within the first casing 407, and all accessories are installed within the receiving space 401 of the first casing 407. Then, the second casing (not shown) is closed over the opening of the receiving space 401 of the first casing 407, thereby forming the outer casing 400. By using the first casing 407 to house the accessories and the second casing (not shown) as a cover, the product size can be reduced, making the product more compact. A button panel 408 is disposed on the second casing.

[0085] The measuring tape structure 420 is installed inside the housing 400. The laser module 410, battery 430, and circuit board 432 are disposed within the space between the edge and axial end face of the measuring tape structure 420 and the inner side of the housing 400, in order to make the most of the space within the housing 400 and reduce the overall size of the ranging device. In some embodiments, such as Figure 30 and 31 As shown, the laser module 410 is disposed at the axial end face of the measuring tape structure 420. A laser beam emitting port facing the emitting surface 414 of the laser module 410 and a light receiving hole facing the light receiving surface 415 of the laser module 410 are respectively provided on the outer surface of the housing 400. The battery 430 is disposed at the radial edge of the measuring tape structure 420, and the length direction of the battery 430 is approximately perpendicular to the axial direction of the measuring tape structure 420. The battery 430 can be a dry cell battery or a rechargeable battery; the battery 430 shown is a rechargeable battery, and a charging port 431 is provided on the side of the housing 400. The circuit board 432 is disposed at the axial end face of the measuring tape structure 420 and fixed to the measuring tape structure 420.

[0086] The ranging device also includes a locking mechanism 440 for tightening or loosening the measuring tape 423. In some embodiments, such as Figure 32As shown, the locking mechanism 440 includes a button 441 and a pressure block 442. One end of the button 441 is connected to the pressure block 442, and the button 441 can drive the pressure block 442 to move together. Under the action of external force, the pressure block 442 can contact and press the tape 423. Preferably, the end of the pressure block 442 away from the button 441 contacts the tape 423, and more preferably, it contacts the part of the tape 423 near the tape outlet 406 of the housing 400. This part of the tape 423 is not wound on the tape measure wheel 422, but is approximately laid flat. The connection between the button 441 and the pressure block 442 is connected to a rotating shaft 444 located inside the housing 400, and the button 441 and the pressure block 442 can rotate through the rotating shaft 444. An elastic element 445 is provided between the pressure block 442 and the outer casing 400. The elastic element 445 applies a spring force to the pressure block 442 to press the pressure block 442 against the tape measure 423. When the button 441 is pressed, the button 441 rotates around the pivot 444 towards the tape measure structure 420, causing the pressure block 442 to rotate away from the tape measure 423, thus releasing the tape measure 423. When the button 441 is released, the spring force applied by the elastic element 445 to the pressure block 442 causes the pressure block 442 to move towards the tape measure 423, and causes the button 441 to move towards the outer casing 400, thus resetting the button 441. The elastic element 445 can be a spring, but it should be understood that the elastic element 445 is not limited to a spring, and can also be other forms of elastic elements 445 that can provide elastic force, such as a spring sheet. The button 441 and the pressure block 442 can be integrally formed.

[0087] like Figure 32 As shown, in this embodiment, a guide member 451 is provided, located inside the housing 400 near the tape outlet 406. The width of the guide member 451 is approximately arc-shaped, forming a channel 4511 through which the tape 324 passes. After passing through this channel, the tape 324 exits the housing 400 from the tape outlet 406. By providing the guide member 451, the tape 423 can be supported, allowing the tape 423 to extend or retract more smoothly from or into the housing 400.

[0088] The ranging device in this embodiment can be equipped with a sensing component 480, which can be any type of sensing component described in Embodiment 1, used to acquire the measurement values ​​of the measuring tape structure 420. This embodiment also provides a structure for the sensing component 480. For example... Figure 32 and 34As shown, the sensing component 480 includes a capacitive grid structure, which consists of two grid plates: a fixed grid 482 and a movable grid 481 arranged opposite to each other. The fixed grid 482 is fixed to the measuring tape structure 420, and the movable grid 481 rotates together with the measuring tape wheel 422. Preferably, the movable grid 481 has a hole 483 in the middle, which is fitted onto the rotating shaft 424 of the measuring tape structure 420, i.e., coaxially arranged with the measuring tape wheel 422. Periodic electrode patterns (not shown in the figure) are engraved on the opposite surfaces of the fixed grid 482 and the movable grid 481. These electrode patterns enable displacement measurement based on capacitance changes. The periodic electrode pattern can continuously change the relative position between the electrodes on the fixed grid 482 and the moving grid 481 when the moving grid 481 moves. The overlapping area between the electrodes on the fixed grid 482 and the moving grid 481 will change, thereby causing a change in capacitance. The change in capacitance will be converted into a change in electrical signal. After processing, these electrical signals can be used to obtain the displacement value. The displacement value and the scale of the ruler are mapped together by an algorithm to realize the digital display of the scale.

[0089] In this embodiment, the display device 433 is disposed between the radial edge of the measuring tape structure 420 and the outer casing 400.
