[0033] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "setting", "connecting" should be understood broadly, for example, it can be fixedly connected, or detachably connected, or integrally connected; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0034] Please refer to Figure 1 The utility model provides a combined measuring tool 10, it aims at solving the problem of the prior art that the functions of laser range finder and laser line projector are split, the operation is complicated, the portability is poor and the measuring precision is low. The tool realizes the high degree of cooperation of the measuring and line projecting functions through the innovative three-surface structure design, the bidirectional mounting function and the forced association (parallel or perpendicular), and significantly improves the operation efficiency and precision.

[0035] Reference Figures 2 to 4 The combined measuring tool 10 includes a first component 100 and a second component 200, one of the first component 100 and the second component 200 is a laser line projector, and the other is a laser range finder. The second component 200 can be selectively mounted on at least two different mounting surfaces of the first component 100, and the laser projection directions of the second component 200 located on the two different mounting surfaces of the first component 100 are different from each other. That is, there can be multiple different mounting surfaces, among the multiple different mounting surfaces, at least two different mounting surfaces exist, so that the laser projection directions of the second component 200 mounted on the two mounting surfaces of the first component 100 are different from each other. Through the combination of the line projector and the range finder on the two different mounting surfaces, the measuring use scenarios are expanded. Through the forced association of the laser directions of the two different mounting surfaces, the consistency of the measuring reference and the projection reference is ensured, the error caused by manual secondary positioning is avoided, the measuring precision is effectively improved, and it is especially suitable for high-precision construction scenarios.

[0036] The following embodiments will focus on the laser projection direction of the second assembly 200 located on two different mounting surfaces being perpendicular to each other, wherein the laser projection direction of the second assembly 200 on one mounting surface is parallel to the laser projection direction of the first assembly 100, and the laser projection direction of the second assembly 200 on the other mounting surface is perpendicular to the laser projection direction of the first assembly 100. However, it should be understood that in other embodiments, the laser projection direction of the second assembly 200 located on different mounting surfaces can also present a non-perpendicular angle state, and the relative positional relationship between the laser projection direction of the second assembly 200 on any mounting surface and the laser projection direction of the first assembly 100 is not limited to parallel or perpendicular, and the angle can be customized according to actual needs.

[0037] The first assembly 100 includes a first surface 110, a second surface 120 and a third surface 130 located in different directions, the first surface 110 is a laser light emitting surface, when the first assembly 100 is a laser line projector, the first surface 110 is used to project the line laser of the first assembly 100, and when the first assembly 100 is a laser range finder, the first surface 110 is used to project the ranging laser of the first assembly 100. The second surface 120 and the third surface 130 are mounting surfaces, for the sake of understanding, the second surface 120 is defined as the first mounting surface, and the third surface 130 is defined as the second mounting surface, and the first mounting surface and the second mounting surface are used to detachably mount the second assembly 200. When the second assembly 200 is mounted on the first mounting surface 120, referring to Figure 1 and Figure 7 , the laser projection direction of the second assembly 200 is parallel to the laser projection direction of the first assembly 100, and the laser projection directions of the two assemblies are the same. When the second assembly 200 is mounted on the second mounting surface 130, referring to Figure 5 and Figure 6 , the laser projection direction of the second assembly 200 is perpendicular to the laser projection direction of the first assembly 100, and the second assembly 200 can be selectively mounted on the second mounting surface 130 in at least two mounting directions that are at an angle to each other. For example, the at least two mounting directions that are at an angle to each other include a first direction and a second direction that are at an angle of 180 degrees to each other. In this embodiment, the first direction can be understood as the upward direction shown in Figure 5 and Figure 9 , and the second direction can be understood as the downward direction shown in Figure 6 and Figure 8 . The second assembly 200 can be selectively mounted upwardly Figure 5 and Figure 9 , or the second assembly 200 is mounted downwardly Figure 6 and Figure 8 , so that the laser projection direction of the second assembly 200 can be selectively set upwardly or downwardly. Of course, in other embodiments, the first direction and the second direction can also be at other angles other than 180 degrees. In addition, Figures 7 to 9The first component 100 is a laser line projector, and the light-emitting surface of the laser line projector projects a cross laser, and a cross positioning mark is presented on the target wall. It should be understood that in other embodiments, the installation orientation of the second component 200 on the second mounting surface 130 can also be fixed, and at this time, the installation orientation of the second component 200 on the second mounting surface 130 does not have the two different orientations described above, and only one orientation can be retained.

[0038] In the embodiment taking the line projector as the main body, the first component 100 is a laser line projector, the first surface 110 projects a horizontal or vertical reference line, and the first mounting surface 120 and the second mounting surface 130 are used to fix the range finder. The second mounting surface 130 supports the vertical installation and direction adjustment of the range finder. For example, in the indoor decoration scene, when the range finder is installed in parallel on the first mounting surface 120, the distance between the walls can be quickly measured; when the range finder is installed vertically on the second mounting surface 130 and downward, the height from the ground to the ceiling can be accurately measured. It is particularly suitable for high-altitude or complex terrain operations.

[0039] In the embodiment taking the range finder as the main body, the first component 100 is a laser range finder, and the first mounting surface 120 and the second mounting surface 130 fix the line projector. In the outdoor surveying scene, the line projector is installed in parallel on the first mounting surface 120 of the range finder to assist in generating a horizontal reference line; when installed vertically, the line projector is stored in the second mounting surface 130 to avoid damage during transportation. This design reduces the volume of the tool by 40%, and is particularly suitable for high-altitude or complex terrain operations.

[0040] The above scheme breaks through the one-way combination limitation of traditional tools and realizes flexible multi-dimensional measurement. Referring to Figures 7 to 9 , the laser measurement tool 10 satisfies the parallel installation mode (the first mounting surface 120) for horizontal distance measurement and the vertical installation mode (the second mounting surface 130) for height measurement, and the second mounting surface 130 supports upward / downward installation, covering complex scenes such as ceilings and floors, realizing single-tool multi-dimensional measurement, reducing the amount of equipment carried, and significantly improving operation efficiency. In the expanded application scene, the range finder can measure the height of the ceiling upward and the reference height of the ground downward in the vertical installation mode; when the line projector is installed on the range finder, it can assist in generating a vertical or horizontal reference line. The present scheme forcibly correlates the laser direction (parallel or vertical) to ensure the consistency of the measurement reference and the projected reference, avoid errors caused by manual secondary positioning, and effectively improve the measurement accuracy, especially suitable for high-precision construction scenes. In summary, the present scheme breaks through the limitation of the fragmentation of traditional tool functions through the core design of “three-surface structure + bidirectional installation”, realizes the high coordination of measurement and line projection functions, and significantly improves the measurement efficiency, accuracy and tool applicability through structural innovation and intelligent adaptation, which has significant practical value.

[0041] In an embodiment, the at least one mounting surface is provided with a baffle 121, the baffle 121 wraps the second assembly 200 and forms a protection structure, at least one side of the baffle 121 forms a side channel 122, the side channel 122 is for the laser of the second assembly 200 to pass through. For example, referring to Figure 1 and Figure 2 , Figure 1 and Figure 2 It is only shown that the first mounting surface 120 is provided with the baffle 121, but it should be understood that the second mounting surface 130 can also be provided with the same baffle 121 structure. Figure 1 and Figure 2 It is shown that the baffle 121 is a circumferentially continuous structure, and the side channel 122 is a light-transmitting gap. At this time, the head and tail of the baffle 121 continuously extend on one side to form the protection structure, and the head and tail of the baffle 121 are spaced apart on the other opposite side to form the light-transmitting gap (one of the side channels 122). It should be understood that in other embodiments, the side channel 122 can also be a light-transmitting plate. When the side channel 122 is a light-transmitting plate, the baffle 121 can be provided as a circumferentially continuous structure, at this time, the wrapping area of the baffle 121 to the second assembly 200 is larger, and the risk of damage to the second assembly 200 by the outside world is further reduced. Figure 2 It is shown that the side channel 122 formed on one side of the baffle 121 is located on the same side as the laser light emitting surface (the first surface 110) of the first assembly 100. In other embodiments, the other side of the baffle 121 opposite to the first surface 110 is also provided with a side channel 122, at this time, the second assembly 200 can have two mounting orientations on the first mounting surface 120, the laser emitting directions of the two mounting orientations are opposite, and the two mounting orientations correspond to the two side channels 122 respectively.

[0042] In an embodiment, the baffle 121 is a three-surface vertical baffle shown in the figure, at this time, the baffle 121 includes a first vertical plate 1211, a second vertical plate 1212 and a third vertical plate 1213 connected in sequence. The first vertical plate 1211, the second vertical plate 1212 and the third vertical plate 1213 are connected to form a U-shaped structure. It should be understood that in other embodiments, the baffle 121 can also have other arbitrary shapes, and the present application is not limited.

[0043] In an embodiment, the second assembly 200 is wrapped by the baffle 121, and the height of the second assembly 200 relative to the mounting surface on which the second assembly 200 is mounted is lower than the height of the baffle 121 relative to the corresponding mounting surface on which the baffle 121 is mounted. For example, the baffle 121 is mounted on the first mounting surface 120, and the second assembly 200 is mounted on the first mounting surface 120, the height of the second assembly 200 relative to the first mounting surface 120 is lower than the height of the baffle 121 relative to the first mounting surface 120. The above arrangement can further ensure that the top of the second assembly 200 is not easily damaged by collision. It should be understood that, without considering the collision damage of the top, the height of the second assembly 200 relative to the mounting surface on which the second assembly 200 is mounted can also be set to be not lower than the height of the baffle 121 relative to the corresponding mounting surface on which the baffle 121 is mounted.

[0044] The first assembly 100 and / or the second assembly 200 comprises a digital display module, that is, at least one of the first assembly 100 and the second assembly 200 is provided with a digital display module, the digital display module is outside the surface where the first assembly 100 and the second assembly 200 are combined, and the digital display module is exposed to the laser measurement tool 10, so that the user can observe the electronic information displayed by the digital display module to facilitate the operation. Referring to Figure 2 and Figure 4 The first mounting surface 120 and the second mounting surface 130 are both provided with a positioning structure 140, the positioning structure 140 comprises a protruding strip 1401 or a recessed groove 1402, and is used for cooperating and fixing with the recessed groove 1402 or the protruding strip 1401 provided on the second assembly 200. In the embodiment, the first mounting surface 120 and the second mounting surface 130 are both provided with the recessed groove 1402, and are used for cooperating and fixing with the protruding strip 1401 provided on the second assembly 200; the recessed groove 1402 provided on the first mounting surface 120 is complementary in shape to the protruding strip 1401 provided on the second assembly 200; the size of the recessed groove 1402 provided on the second mounting surface 130 is greater than the size of the protruding strip 1401 provided on the second assembly 200, so as to allow the protruding strip 1401 provided on the second assembly 200 to be accommodated in the recessed groove 1402 when the second assembly 200 is mounted on the second mounting surface 130 in different mounting orientations.

[0045] The second assembly 200 corresponds to the protruding strip 1401 arranged at least two sub-strips 1403, 1404 with different shapes, and a part of the large-size sub-strip 1403 has the same shape and size as the small-size sub-strip 1404. The recessed groove 1402 arranged on the first mounting surface 120 includes at least two sub-grooves 1405, 1406 with different shapes, and the two sub-strips 1403, 1404 are complementary to the two sub-grooves 1405, 1406 of the first mounting surface 120 in shape. The recessed groove 1402 arranged on the second mounting surface 130 includes two sub-grooves 1405 with the same shape, and the sub-groove 1405 of the second mounting surface 130 is complementary to the large-size sub-strip 1403 of the two sub-strips 1403, 1404 of the second assembly 200 in shape.

[0046] In an embodiment, the second assembly 200 is positioned on different mounting surfaces of the first assembly 100 by a magnet. Specifically, the first mounting surface 120 and the second mounting surface 130 are both provided with magnetic attraction components, and the second assembly 200 is provided with magnets matched with the magnetic attraction components. The second assembly 200 is installed on the first mounting surface 120 and the second mounting surface 130 by the magnets. The magnetic attraction components can be metal components, and the magnets can be automatically aligned and installed to the target position by magnetic attraction between the magnets and the metal when the magnets are installed on the first mounting surface 120 and the second mounting surface 130. In another embodiment, the magnetic attraction components can also be another type of magnet different from the magnet. In specific use, the second assembly 200 can also be used alone by magnetic attraction to the metal wall surface.

[0047] In an embodiment, when the second assembly 200 is installed in parallel with the first assembly 100, the laser light emitting surface of the first assembly 100 is parallel to the laser light emitting surface of the second assembly 200, that is, the two laser light emitting surfaces can be located in the same plane, or can be two parallel planes with a certain distance, to ensure that the light paths are aligned. When the second assembly 200 is installed perpendicularly to the first assembly 100, the laser light emitting surface of the first assembly 100 is located in a plane perpendicular to the laser light emitting surface of the second assembly 200, and the window is located in the orthogonal plane to avoid interference of the light beams. This design has a significant effect in the pipeline arrangement scene, and the light beams of the line projection instrument and the distance meter do not interfere with each other, and the measurement accuracy is further improved.

[0048] In an embodiment, the first assembly 100 is internally integrated with a power supply sharing module including at least one of a contact and a wireless coil, for supplying power to the second assembly 200 when the second assembly 200 is installed on the first assembly 100. The power supply sharing module realizes power transmission from the first assembly 100 to the second assembly 200 through two technical paths, namely contact power supply and wireless charging. When the second assembly 200 is installed on the first assembly 100, the physical connection or spatial coupling of the two triggers the power supply process, ensuring that the second assembly 200 continuously obtains power support in the combined state, thereby reducing the user's trouble of frequently replacing batteries or charging separately.

[0049] In the contact power supply scheme, metal contacts are arranged on the mounting surface of the first component 100, and conductive tabs are designed at the corresponding positions of the second component 200. When the second component 200 is mounted to the first component 100 through the positioning structure 140 and / or magnetic attraction structure, the conductive tabs are precisely connected with the metal contacts to form a closed circuit. The layout of the contacts is usually designed symmetrically, for example, positive and negative contacts are arranged on both sides of the mounting surface, to ensure that the polarity can be automatically matched no matter which direction the second component 200 is installed. To improve the contact reliability, the surface of the contacts is plated with gold to reduce the resistance, and elastic structures (such as spring pins) are embedded to compensate for the poor contact problem caused by mechanical tolerance or slight misalignment. For example, in the construction scene, even if the tool is slightly displaced due to vibration, the elastic contacts can still maintain stable conduction to avoid power interruption.

[0050] In the wireless charging scheme, the wireless charging scheme is based on the principle of electromagnetic induction. The first component 100 is integrated with a transmitting coil inside, and the second component 200 is built-in with a receiving coil. When they are installed in place, the spatial position of the transmitting coil and the receiving coil meets the electromagnetic coupling condition, and the first component 100 transmits electric energy to the second component 200 through the alternating magnetic field. The key of this scheme lies in the precise alignment design of the coils. The mounting surface of the first component 100 is provided with a positioning structure to ensure that the axis of the receiving coil coincides with that of the transmitting coil when the second component 200 is installed, maximizing the energy transmission efficiency. For example, in the indoor decoration scene, when the user adsorbs the range finder to the second mounting surface of the line projector, the coils are automatically aligned, and the charging efficiency can be greatly improved, close to the level of wired charging. To adapt to different power requirements, the system supports dynamic tuning. When it is detected that the second component 200 is a high-power module (such as a line projector with laser mapping function), the output power is automatically increased.

[0051] The two power supply modes can work independently or cooperatively. In the preferred embodiment, the first component 100 integrates both contact and wireless coil, and the user can choose flexibly according to the use environment. For example, in a humid or dusty outdoor work site, wireless charging is preferred to avoid contact oxidation; while in an emergency situation requiring rapid power supply, switching to contact power supply can take advantage of its higher efficiency. The system has a built-in intelligent switching circuit that automatically selects the optimal power supply mode by detecting the interface type (such as contact impedance or wireless signal) of the second component 200, without the need for manual intervention. In addition, the power supply sharing module also contains multiple protection mechanisms: over-voltage and over-current protection chips prevent device damage, and foreign object detection function identifies metal debris during wireless charging and cuts off the power supply, ensuring safe use. From the perspective of user experience, the design of the power supply sharing module significantly improves the operational convenience of the tool. Users do not need to carry additional charging cables or disassemble the battery, and only need to install the second component 200 to the first component 100 to complete the charging. For example, in continuous operation, workers use the range finder for measurement during the day, and install it on the line projector at night, so that it can be in full power state the next day, avoiding delays due to insufficient power, especially suitable for field survey scenarios where stable power supply is lacking.

[0052] In an embodiment, the second component 200 is built-in with a position sensor, which includes a signal collector. The position sensor is used to sense the first mounting surface 120 or the second mounting surface 130 of the first component 100 that it is installed on, and automatically switch the measurement mode or the line projection mode according to the type of mounting surface. Specifically, the position sensor intelligently identifies the installation position and direction by sensing the physical connection state of the second component 200 and the first component 100, and triggers the corresponding function mode switching. The core principle is to convert the physical information of mechanical installation into electrical signals, and realize automatic operation through logical judgment, thereby reducing manual intervention and improving the response speed and operation accuracy of the tool.

[0053] When the second component 200 is mounted to the first mounting surface 120 of the first component 100 through the positioning structure 140 or the magnetic attraction structure, the position sensor first detects the magnetic field characteristics or optical markers of the mounting surface. For example, in the magnetic sensor scheme, the first mounting surface 120 of the first component 100 is embedded with a permanent magnet of a specific polarity, and the second mounting surface 130 adopts a magnet array with different magnetic field strengths. The Hall sensor (one of the signal collectors) inside the second component 200 determines whether the current mounting surface is the first mounting surface 120 or the second mounting surface 130 by measuring the magnetic field strength and direction. If the magnetic field characteristics of the first mounting surface 120 (such as the north pole facing) are detected, the sensor sends a signal to the master chip to trigger the "parallel measurement mode", at which time the distance meter automatically calibrates to horizontal direction measurement, or the line projector adjusts to horizontal laser projection; if the magnetic field characteristics of the second mounting surface 130 (such as the south pole facing and the magnetic field gradient changing) are detected, it switches to the "vertical measurement mode", the distance meter starts the height measurement algorithm, or the line projector switches to vertical laser line projection.

[0054] For the determination of the installation direction (such as the second mounting surface 130 facing up or down), the sensor can also include a gyroscope (one of the signal collectors), and the sensor further combines the accelerometer or gyroscope data. When the second component 200 is mounted to the second mounting surface 130, the built-in six-axis gyroscope monitors the spatial posture of the tool in real time. If the tool is in the upright state (the line projector reference surface is horizontal and faces forward), the gyroscope detects that the Z-axis gravity component is positive, and determines that it is "installed downward", triggering the downward vertical measurement mode, which is suitable for ground-to-wall height measurement; if the tool is inverted (the reference surface is horizontal and faces backward), the Z-axis gravity component is negative, and it is determined to be "installed upward", starting the upward vertical measurement mode, which is suitable for ceiling height or high-altitude pipeline positioning. This multi-sensor fusion design not only ensures the reliability of the mounting surface recognition, but also realizes the accuracy of the direction determination.

[0055] In actual application, the mode switching process is accompanied by clear user feedback. For example, in a construction site scenario, when the worker installs the distance meter to the first mounting surface 120 of the line projector, the position sensor recognizes the parallel installation state, the master chip automatically turns off the vertical laser line of the line projector, and only the horizontal line projection is retained, while the distance meter screen displays the "horizontal mode" mark and activates the continuous distance measurement function. If the distance meter is installed to the second mounting surface 130 upward by rotating 180 degrees, the sensor determines it as "vertical upward mode" through the magnetic field and gyroscope data, the line projector immediately switches to vertical laser line projection, the distance meter screen displays the "vertical ↑" symbol, and the single-precision height measurement function is started. This seamless switching allows workers to operate without stopping to adjust the equipment in complex environments, significantly improving the continuity of the operation.

[0056] In terms of technical implementation, the processing flow of the sensor signal includes three key stages: signal acquisition, logic judgment and instruction execution. In the signal acquisition stage, the hardware such as the Hall sensor and the gyroscope captures the physical parameters of the installation surface in real time; in the logic judgment stage, the master chip compares the original data with the preset threshold library (for example, the first installation surface magnetic field strength threshold is 50-70 mT, and the second installation surface is 30-40 mT), and determines the current installation state through the decision tree algorithm; in the instruction execution stage, the chip sends control commands to the laser module, the distance measuring module and the display unit to complete mode switching. The response time of the whole process is controlled within 200 milliseconds, and the user almost cannot feel the delay.

[0057] The advantage of the design is particularly prominent in differentiated scenarios. For example, in indoor decoration ceiling operation, after the worker first installs the distance measuring instrument to the first installation surface 120 to complete the wall surface distance measurement, the worker dismounts it and installs it to the second installation surface 130 upward. The position sensor immediately recognizes the state change, the line projector automatically closes the horizontal line and projects a vertical laser line to the ceiling, and the distance measuring instrument synchronously switches to the upward measurement mode to directly read the suspended ceiling installation height value. The whole process does not need to manually press the mode switching button, nor does it need to adjust the equipment parameters by referring to the instruction manual, and the function adaptation is completed autonomously, so that the worker can focus on the construction quality rather than the equipment operation.
