[0038] Detailed Implementation

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0040] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0041] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0042] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0043] like Figure 1 and Figure 2As shown in the illustration, this application also proposes a wall measurement device, including a measurement module 100, a truss assembly 200, and a drive assembly 300. The measurement module 100 is used to measure the wall to be measured, thereby acquiring measurement data. For example, the measurement module 100 can be an ultrasonic ranging sensor, an infrared ranging sensor, or a laser ranging sensor, etc., to acquire the dimensions of the wall. The truss assembly 200 includes a frame 220 and a scanning bracket 210; the measurement module 100 is mounted on the scanning bracket 210; the scanning bracket 210 is movably connected to the frame 220. In this embodiment, the measurement module 100 is mounted on the scanning bracket 210. A drive component 300 is provided on the frame 220. The drive component 300 can drive the scanning bracket 210 to move relative to the frame 220, and thus move relative to the wall being measured. This enables scanning of the wall being measured at different positions, eliminating the need for manual adjustment of the measurement module 100, reducing the complexity of the measurement process, and reducing operational errors caused by human operation, thereby improving the accuracy and reliability of the measurement data.

[0044] In one embodiment, the truss assembly 200 has a rectangular construction to accommodate most rectangular embedded walls. In other embodiments, the truss assembly 200 can be configured to fit the specific shape of the wall being measured, depending on the required measurement.

[0045] In an embodiment, such as Figure 3 and Figure 4 As shown, at least two sides of the truss assembly 200 abut against the cavity wall of the wall being measured, so that the wall measuring device is stabilized within the wall groove 01 of the wall being measured. The scanning bracket 210 can move left and right or up and down under the drive of the drive assembly 300, so as to measure the wall being measured at different left and right positions or up and down positions.

[0046] For example, such as Figure 3 As shown, taking an ultrasonic ranging sensor as the measurement module 100 as an example, the left and right sides of the truss assembly 200 are abutted against the left and right sides of the wall groove 01; under the drive of the drive assembly 300, the scanning bracket 210 begins to move, and the ultrasonic sensor begins to emit and receive ultrasonic waves at a certain frequency to scan the distance between the top and bottom of the wall at different vertical positions.

[0047] For example, such as Figure 4 As shown, taking an ultrasonic ranging sensor as the measurement module 100 as an example, the left and right sides of the truss assembly 200 are abutted against the upper and lower sides of the wall groove 01; under the drive of the drive assembly 300, the scanning bracket 210 begins to move, and the ultrasonic sensor begins to emit and receive ultrasonic waves at a certain frequency to scan the width distance of the wall at different left and right positions.

[0048] As an optional implementation of the above embodiments, the driving assembly 300 includes a driving motor 340 and a transmission mechanism; the driving motor 340 is mounted on the frame 220; the driving motor 340 is connected to the scanning bracket 210 through the transmission mechanism. In this embodiment, the driving motor 340 is mounted on the frame 220. The driving motor 340 can be a stepper motor. In some embodiments, the driving motor 340 can also be a DC motor or an AC motor. The transmission mechanism is used to convert the power output by the driving motor 340 into the power to drive the scanning bracket 210 to move.

[0049] In other embodiments, the drive assembly 300 may also be an electric actuator, a hydraulic actuator, etc.

[0050] In some cases, the embedded wall has a square structure, thus requiring the measurement of the width or height of its wall groove 01. Therefore, in some embodiments of this application, as an optional implementation of the above embodiments, the transmission mechanism is a linear transmission mechanism. In the embodiments, the scanning bracket 210 moves linearly, for example... Figure 2 and Figure 6 As shown, the vertical scanning motion is used to measure the wall at different locations; for example, it could be... Figure 7 As shown, the left and right motion scan.

[0051] In some embodiments, such as Figure 2 and Figure 7 As shown, the linear transmission mechanism can be a gear 320 and rack 310 mechanism. One end of the scanning bracket 210 is fixedly connected to the rack 310, and the gear 320 meshes with the rack 310; the gear 320 is connected to the drive motor 340 through a transmission shaft. The drive motor 340 drives the gear 320 to rotate, the rack 310 to move, and thus drives the scanning bracket 210 to move.

[0052] In some embodiments, such as Figure 6 As shown, the linear transmission mechanism can be a lead screw and nut mechanism. A nut 212 is provided on the scanning bracket 210. The lead screw 330 is screwed into the nut 212; the lead screw 330 is connected to the drive motor 340. The drive motor 340 drives the lead screw 330 to rotate, the nut 212 moves, and thus the scanning bracket 210 moves.

[0053] In other cases, the embedded wall can be an irregular or curved structure, so the transmission mechanism can be specifically designed according to the specific shape of the wall. For example, the transmission mechanism can also be a gear mechanism, a linkage mechanism, etc.

[0054] As an optional implementation of the above embodiments, one of the scanning bracket 210 and the frame 220 is provided with a sliding groove S, and the other is provided with a sliding block 211; the sliding block 211 is slidably engaged with the sliding groove S. In some embodiments, the sliding block 211 engages with the sliding groove S, and the sliding block 211 can slide within the sliding groove S, thereby allowing the scanning bracket 210 to move by means of the sliding pair formed between the sliding block 211 and the sliding groove S. For example, in some embodiments, the sliding groove S is provided on the frame 220, and in other embodiments, the sliding groove S is provided on the scanning bracket 210.

[0055] In some embodiments, one end of the scanning bracket 210 is connected to the transmission mechanism, and the other end is configured as a sliding block 211. In this way, both opposite ends of the scanning bracket 210 are supported.

[0056] For example, as shown in Figure 8, the scanning bracket 210 extends in the vertical direction. One end of the scanning bracket 210 in the vertical direction is connected to the transmission mechanism, and the other end is set as a sliding block 211.

[0057] For example, refer to Figure 5 and Figure 6 As shown, the scanning bracket 210 extends in the left-right direction. One end of the scanning bracket 210 in the left-right direction is connected to the transmission mechanism, and the other end is set as a sliding block 211. For example, as... Figure 9 and Figure 10 As shown, a sliding block 211 is provided at one end of the scanning bracket 210.

[0058] To accommodate more sizes of embedded walls, in one embodiment, as an optional implementation of the above embodiments, the frame 220 includes a fixed bracket and a telescopic bracket 224; the telescopic bracket 224 is connected to the fixed bracket and configured to be telescopic along a preset direction; the scanning bracket 210 is movably connected to at least one of the telescopic bracket 224 and the fixed bracket. In this embodiment, the telescopic bracket 224 is adjusted to abut against the wall surface of the embedded wall. The telescopic bracket 224 is adjusted to adapt to different wall sizes or different directions during measurements.

[0059] For example, 2 and Figure 11 As shown, the telescopic bracket 224 can extend and retract relative to the fixed bracket in the left-right direction. Figure 2 As shown, the telescopic bracket 224 is in the retracted state, which can be used when the width is small; as Figure 11 As shown, the telescopic bracket 224 is in the extended state and can be used when the width is large.

[0060] In some embodiments, the telescopic support 224 may include a telescopic rod, one end of which is connected to a fixed support, and the other end of which is connected to the frame 2241 of the telescopic support 224. In some embodiments, the telescopic support 224 includes a rod body, one end of which extends into the fixed support and can move along the fixed support.

[0061] In some embodiments, the scanning bracket 210 can move along the fixed bracket, such as Figure 8 As shown, it can also move along the telescopic bracket 224, as... Figure 11 As shown.

[0062] In some embodiments, there may be one or two telescopic brackets 224. There may be three fixed brackets, with two fixed brackets arranged opposite each other, one end of each fixed bracket movably connected to a telescopic bracket 224, and the other end also fixedly connected to another fixed bracket. Alternatively, there may be two fixed brackets, with two fixed brackets arranged opposite each other, one end of each fixed bracket movably connected to a telescopic bracket 224, and the other end movably connected to another telescopic bracket 224.

[0063] As an optional implementation of the above embodiments, such as Figure 8 and Figure 11 As shown, the fixed bracket includes a first bracket 221 and a second bracket 222; the telescopic bracket 224 and the second bracket 222 are arranged opposite to each other. The first bracket 221 and the second bracket 222 are intersecting each other and fixedly connected. In some embodiments, the first bracket 221 and the second bracket 222 are perpendicular to each other and fixedly connected. The first bracket 221 and the second bracket 222 can be welded or connected by threaded connectors. In some embodiments, the first bracket 221 and the second bracket 222 are arranged at an included angle, and the specific value of the included angle can be set according to the specific shape and structure of the wall.

[0064] like Figure 11 As shown, the telescopic bracket 224 includes a frame 2241 and a first rod 2242 disposed on the frame 2241, the first rod 2242 being movably connected to the first bracket 221. In an embodiment, the first rod 2242 is fixedly disposed on the frame 2241. The first rod 2242 is movable relative to the first bracket 221; for example, the first rod 2242 can extend to the first bracket 221 and slide relative to the first bracket 221. The specific connection structure between the first rod 2242 and the first bracket 221 can refer to the mating structure of the sliding block 211 and the sliding hole H.

[0065] As an optional implementation of the above embodiments, the fixed bracket further includes a third bracket 223, which is disposed opposite to the first bracket 221; the two opposite ends of the second bracket 222 are respectively fixedly connected to the first bracket 221 and the third bracket 223. In an embodiment, the third bracket 223 and the first bracket 221 are disposed opposite to each other, and the second bracket 222 and the telescopic bracket 224 are disposed opposite to each other, forming a quadrilateral frame 220. In a specific embodiment, the first bracket 221, the second bracket 222, the third bracket 223, and the telescopic bracket 224 form a rectangular frame 220.

[0066] The telescopic bracket 224 further includes a second rod 2243 disposed on the frame 2241, and the second rod 2243 is movably connected to the second bracket 222. In an embodiment, the second rod 2243 is fixedly disposed on the frame 2241. The second rod 2243 is movable relative to the third bracket 223; for example, the second rod 2243 can extend to the third bracket 223 and slide relative to the first bracket 221. The specific connection structure between the second rod 2243 and the third bracket 223 can refer to the mating structure of the sliding block 211 and the sliding hole H.

[0067] In one specific embodiment, such as Figure 11 and Figure 12 As shown, the first rod 2242 and the second rod 2243 are located at both ends of the extension direction of the frame 2241.

[0068] As an optional implementation of the above embodiments, such as Figure 9 and Figure 10 As shown, the telescopic bracket 224 is provided with a sliding groove S; the scanning bracket 210 is provided with a sliding block 211; the sliding block 211 is slidably engaged with the sliding groove S. In an embodiment, the sliding block 211 engages with the sliding groove S so that the sliding block 211 can slide on the telescopic bracket 224. Figure 9 and Figure 10 As shown, the scanning bracket 210 is provided with a sliding hole H, which extends along the extension direction of the telescopic bracket 224. The sliding block 211 is slidably engaged with the sliding hole H. In an embodiment, the sliding block 211 and the sliding hole H can cooperate, and when the sliding block 211 slides within the sliding hole H, the telescopic bracket 224 can extend and retract along the extension direction of the sliding hole H; for example... Figure 9 The telescopic bracket 224 is in a shortened state; as described above. Figure 10 As shown, the telescopic bracket 224 is in the extended state.

[0069] In this embodiment, the sliding block 211 is provided with a first limiting block 2111 and a second limiting block 2112. The first limiting block 2111 cooperates with the wall of the sliding groove S to prevent the sliding block 211 from sliding out of the sliding groove S. When the telescopic bracket 224 extends to the preset longest position, the second limiting block 2112 cooperates with the wall of the sliding hole to prevent the sliding block 211 from sliding out of the sliding hole H. Both the first limiting block 2111 and the second limiting block 2112 can be constructed as elastic buckles. During assembly, the elastic buckles deform to engage with the sliding groove S and the sliding hole H respectively. After assembly, the elastic buckles return to their original shape to restrict the sliding block 211 from sliding out of the sliding groove S and from sliding out of the sliding hole H.

[0070] Figure 12 As shown, the slide S extends along the extension direction of the telescopic bracket 224 and is located between the first rod 2242 and the second rod 2243.

[0071] As an optional implementation of the above embodiments, such as Figure 11 As shown, the wall measuring device further includes a fixing member 500, which is used to fix the telescopic bracket 224 and the fixed bracket when the telescopic bracket 224 is extended to a preset position, and / or fix the telescopic bracket 224 and the scanning bracket 210. In an embodiment, when the telescopic bracket 224 is extended to the preset position, the telescopic bracket 224 abuts against the wall surface of the embedded wall; the fixing member 500 fixes the telescopic and fixed brackets and / or the scanning bracket 210 so that the telescopic bracket 224 is held in the current preset position, thereby enabling the measuring device to be stably embedded in the wall.

[0072] During the actual measurement, the second bracket 222, which is opposite to the telescopic bracket 224, is first abutted against one side of the wall; then the telescopic bracket 224 is adjusted to abut against the other side of the wall, and the telescopic bracket 224 is locked to the fixed bracket by the fixing bracket so that the measuring device can be stably placed in the wall, and then the measurement is started.

[0073] In some embodiments, the scanning bracket 210 and the telescopic bracket 224 can be vertically connected, and the telescopic bracket 224 can extend and retract relative to the scanning bracket 210 in the left-right direction. During a specific measurement, the second bracket 222, which is positioned opposite the telescopic bracket 224, is pre-fitted against one side of the wall; then the telescopic bracket 224 is adjusted to fit against the other side of the wall. The telescopic bracket 224 and the scanning bracket 210 are locked together using a fixing frame, restricting the left-right freedom of the telescopic bracket 224 so that the measuring device can be stably fixed within the wall, and then the measurement begins.

[0074] In this embodiment, the fastener 500 may be a positioning pin, screw, or the like.

[0075] In some embodiments, elastic blocks, such as rubber blocks, can be attached to the outer contact surfaces of the telescopic bracket 224 and its oppositely arranged second bracket 222; the telescopic bracket 224 extends and retracts to adjust the elastic blocks, thereby improving the stability of the measuring device within the wall.

[0076] As an optional implementation of the above embodiments, the measurement direction of the measurement module 100 is at least one side of the moving direction of the scanning bracket 210. In an embodiment, for example, the scanning bracket 210 moves up and down, and the measurement direction is up and down; taking an ultrasonic ranging sensor as an example, when the ultrasonic wave moves up and down during scanning, it emits ultrasonic waves upward or downward (measurement direction). After the ultrasonic wave encounters a wall, it is reflected and the echo is received, thereby measuring the height of the embedded wall.

[0077] In some embodiments, the measurement direction of the measurement module 100 is oriented towards both sides of the moving direction of the scanning bracket 210; for example, when the ultrasonic wave moves up and down during scanning, it simultaneously emits ultrasonic waves upward and downward (measurement direction). After the ultrasonic wave encounters the wall, it is reflected and the echo is received, thereby measuring the height of the embedded wall.

[0078] In some technical solutions of the embodiments of this application, the measurement module 100 may include a plurality of ranging sensors; the ranging sensors are arranged in an array along the extension direction of the scanning bracket 210.

[0079] like Figure 2 As shown, a horizontal sensor 400 is provided on the frame 220. In this embodiment, the horizontal sensor 400 facilitates the determination of whether the wall measuring device is in a horizontal position, avoiding measurement under skewed conditions and improving the accuracy of the measurement results. In this embodiment, the horizontal sensor 400 can be set on a first support 221 in the horizontal direction and / or on a second support 222 in the vertical direction.

[0080] like Figure 13 As shown, the wall device in this embodiment further includes a control module. The control module receives measurement data from the measurement module 100. During the movement of the scanning bracket 210, the measurement module 100 performs measurements. The control module can process the measurement data from different positions to obtain the height, width, or tilt of the embedded cavity. The control module can be connected to the measurement module 100 via a communication module, such as a Bluetooth module, or via a signal cable.

[0081] In this embodiment, the control module can also be connected to the drive component 300 via a communication module or signal line to output control commands to the drive component 300 so that the drive component 300 drives the scanning bracket 210 to move according to the control commands.

[0082] In this embodiment, the control module can also be connected to the level sensor 400 via a communication module or signal line; after the level sensor 400 detects that the measuring device is level, it sends a signal to the control module; the control module then starts to control the scanning bracket 210 to perform the measurement.

[0083] In this embodiment, the control module can also be connected to the display screen via a ribbon cable, allowing the user to view measurement data and results promptly, such as displaying wall tilt. The display screen is an OLED display, providing clear and intuitive visuals. In some embodiments, the controller transmits the analyzed measurement data to the application terminal via a Bluetooth module. The Bluetooth module is a commonly available low-power, high-transmission-rate module, soldered onto the controller's circuit board to achieve connection with the controller. The application terminal can be the user's electronic device, etc.

[0084] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application.
