[0032] This application provides an external device, a handle using the external device, and a scanning system using the handle. The handle provided in this application can be connected to a scanning device to form the scanning system provided in this application. The scanning system is used to perform three-dimensional scanning of an object to obtain its external dimensions or appearance. In some embodiments, the scanning device 300 can be at least one of a grating 3D scanner, a structured light 3D scanner, and a laser 3D scanner.

[0033] Please refer to the following: Figure 1 and Figure 5 The external device 100 provided in the embodiments of this application will now be described.

[0034] The external device 100 provided in this application is detachably connected to the scanning device 300 to form a scanning system. The external device 100 includes an interface module 12, a transceiver module 13, a main control module 11, and a battery module 14. The interface module 12 is detachably electrically connected to the scanning device 300 and is used to receive scanning data obtained by the scanning device 300 from scanning the object under test. The main control module 11 is electrically connected between the interface module 12 and the transceiver module 13 and is used to transmit the scanning data received by the interface module 12 from the scanning device 300 to the transceiver module 13. It is also used to send control command signals and transmit them to the scanning device 300 through the interface module 12 to control the working state of the scanning device 300. The transceiver module 13 is adapted to wirelessly connect with the host computer 500 and is used to transmit the scanning data to the host computer 500 for further processing and to receive control command signals issued by the host computer 500 and transmit them to the main control module 11.

[0035] like Figure 1As shown, the interface module 12 is electrically connected to the scanning device 300. The interface module 12 can transmit the control command signals in the main control module 11 to the scanning device 300, and the interface module 12 can receive the scanning data in the scanning device 300 and transmit the scanning data to the main control module 11, thereby realizing the communication connection between the external device 100 and the scanning device 300 through the interface module 12.

[0036] In some embodiments, the transceiver module 13 includes at least one high-speed wireless communication unit such as a WIFI transceiver unit, a 5G mobile communication unit, or a millimeter-wave communication unit. It is understood that the host computer 500 is a host computer with wireless communication capabilities, such as a mobile phone, tablet computer, or computer—a smart terminal with high computing power. The host computer 500 is used to receive scanning data obtained by the scanning device 300, and can also transmit control command signals to the scanning device 300 so that the scanning device 300 operates according to the control command signals.

[0037] like Figure 1 As shown, the main control module 11 is electrically connected between the interface module 12 and the transceiver module 13. The main control module 11 can transmit the scan data received by the interface module 12 to the transceiver module 13, so that the transceiver module 13 can convert the scan data into electromagnetic wave signals and transmit them to the host computer 500, thereby realizing the real-time transmission of the scan data obtained by the scanning device 300 to the host computer 500.

[0038] In addition, the main control module 11 can transmit the control command signals received by the transceiver module 13 to the scanning device 300 through the interface module 12. In some embodiments, the control command signals include scanning parameter commands, and the scanning device 300 can adjust the scanning mode, start / pause scanning, and other working states according to the scanning parameter commands.

[0039] The main control module 11 of the external device 100 provided in this application is electrically connected between the interface module 12 and the transceiver module 13. The scanning data acquired by the interface module 12 is wirelessly transmitted to the host computer 500 through the transceiver module 13, reducing the number of wires on the scanning device 300, thereby reducing the distance limitation between the scanning device 300 and the host computer, and avoiding data disconnection caused by poor contact of the data transmission line between the scanning device 300 and the host computer. Thus, the external device 100 provided in this application has the advantage of improving the portability of the scanning system.

[0040] In some embodiments provided in this application, the external device 100 further includes a battery module 14, which is electrically connected to the main control module 11 and is used to supply power to the interface module 12, the transceiver module 13, and the main control module 11. The battery module 14 is also electrically connected to the interface module 12 via the main control module 11, so as to supply power to the scanning device 300 through the interface module 12. Specifically, as follows... Figure 1 As shown, battery module 14 is electrically connected to main control module 11, transmitting the electrical energy stored in battery module 14 to main control module 11. Main control module 11 then transmits the electrical energy stored in battery module 14 to interface module 12 and transceiver module 13 to power interface module 12 and transceiver module 13. Interface module 12 is electrically connected to battery module 14 through main control module 11, enabling interface module 12 to communicate with scanning device 300 while simultaneously supplying power to scanning device 300.

[0041] Therefore, the main control module 11 distributes the power of the battery module 14 to the interface module 12 and the transceiver module 13, and supplies power to the scanning device 300 through the battery module 14 built into the external device 100. This eliminates the need for an external power cable for the scanning device 300, reduces the number of wires connected to the scanning device 300, and further improves the portability of the scanning system.

[0042] In some embodiments provided in this application, the interface module 12 includes a data transmission unit 121, which is electrically connected to the scanning device 300 to convert the scanning data obtained by the scanning device 300 into digital signals and transmit them to the host computer 500 and / or transmit control command signals to the scanning device 300 and / or supply power to the scanning device 300.

[0043] like Figure 1 As shown, the data transmission unit 121 is connected to the battery module 14 through the main control module 11. However, the data transmission unit 121 supplies power to the scanning device 300 while transmitting data between the scanning device 300 and the main control module 11, resulting in a relatively small power output from the data transmission unit 121 to the scanning device 300. When the power consumption of the scanning device 300 is high, the data transmission unit 121 alone cannot meet the requirements. Therefore, the interface module 12 also includes a power supply unit 122, which is electrically connected to the scanning device 300 and is used solely to supply power to the scanning device 300. The output power of the power supply unit 122 is greater than the output power of the data transmission unit 121.

[0044] In one embodiment, the main control module 11 includes a main control unit 111 and a power management unit 112. The power management unit 112, under the control of the main control unit 111, distributes power to each module in the external device 100. For example... Figure 1As shown, the power supply unit 122, located on the interface module 12, is electrically connected to the main control module 11. Under the allocation of the power management unit 112 in the main control module 11, the power supply unit 122 transmits the electrical energy from the battery module 14 to the scanning device 300. The power supplied by the power supply unit 122 to the scanning device 300 is greater than the power supplied by the data transmission unit 121 to the scanning device 300. Preferably, the data transmission unit 121 is a USB communication interface, and the power supply unit 122 is a DC power interface.

[0045] Therefore, when the input power of the scanning device 300 is less than the output power of the data transmission unit 121, the scanning device 300 only needs to be electrically connected to the data transmission unit 121, which reduces the number of wires between the scanning device 300 and the external device 100, thereby reducing the probability of poor contact between the scanning device 300 and the external device 100. When the input power of the scanning device 300 is greater than the output power of the data transmission unit 121, the scanning device 300 is electrically connected to the power supply unit 122 to supply power to the scanning device 300, thus meeting the power requirements of different models of scanning devices 300.

[0046] In some embodiments, the interface module 12 further includes a signal processing unit 123, which amplifies the digital signal obtained by the data transmission unit 121 based on the scanning data of the scanning device 300 so that the main control module 11 can receive and process it, thereby reducing the impact of signal attenuation.

[0047] In some embodiments provided in this application, the external device 100 further includes a charging module 15, which is electrically connected to the battery module 14 to charge the battery module 14. Thus, by supplying power to the battery module 14 through the charging module 15, the battery module 14 can be restored to its energy reserves without needing to be replaced, thereby improving the portability of the scanning system provided in this application.

[0048] In the several embodiments provided in this application, it should be understood that the device embodiments described above are merely illustrative. For example, the division of modules or units is only a logical functional division, and in actual implementation, there may be other division methods. For example, multiple units or components may be combined or integrated into another system, or some features may be ignored or not executed. The units described as separate components may or may not be physically separated, that is, they may be located in one place or distributed across multiple units. Some or all of the units may be selected to achieve the purpose of the solution in this embodiment according to actual needs. In addition, the functional units in the various embodiments of this application may be integrated into one unit, or each unit may exist physically separately, or two or more units may be integrated into one unit.

[0049] The following is combined with Figures 1 to 5 The handle 200 provided in this application will be described. It should be noted that the first direction in the following text is the z-direction (i.e., the vertical direction) shown in the figure, the second direction in the following text is the x-direction shown in the figure, and the third direction in the following text is the y-direction shown in the figure. The first direction, the second direction, and the third direction are perpendicular to each other.

[0050] like Figures 2 to 5 As shown, the handle 200 provided in this application includes the external device 100 in any of the above embodiments. The handle 200 also includes a housing 21, which has an inner cavity 216 in which the external device 100 is accommodated; and a first connecting component 24, which is disposed on the outside of the housing 21 and is adapted to be detachably connected to the scanning device 300. Figure 2 and Figure 3 As shown, the housing 21 extends along the first direction z so that the user can hold the handle 200 circumferentially along the housing 21. The housing 21 has an inner cavity 216 in which the external device 100 is accommodated. The first connecting component 24 is disposed at the end of the housing 21 in the first direction z, and the scanning device 300 is detachably connected to the first connecting component 24.

[0051] The handle 200 provided in this application is wirelessly connected to the host computer of the scanning device 300 installed on the first connection component 24 through the transceiver module 13 of the external device 100 housed therein, so as to reduce the number of wires on the scanning device 300 and improve the portability of the scanning system.

[0052] Therefore, by setting the housing 21 so that the user can hold the external device 100, the portability of the scanning system is further improved. The scanning device 300 is detachably connected to the first connecting component 24 so as to replace the scanning device 300 installed on the handle 200 provided in this application, thereby improving the versatility of the handle 200.

[0053] In some embodiments provided in this application, the first connection component 24 includes a snap-fit ​​member 242 and a first quick-connect member 241 connected to the snap-fit ​​member 242. The snap-fit ​​member 242 is disposed on the outside of the housing 21. The first quick-connect member 241 is detachably connected to the scanning device 300 and can snap onto the snap-fit ​​member 242.

[0054] In some embodiments, such as Figure 4 As shown, the first quick connector 241 is provided with a threaded part 2411, which extends along the first direction z. The threaded part 2411 can be threadedly connected to the scanning device 300 so as to detachably connect the first quick connector 241 to the scanning device 300.

[0055] like Figures 2 to 5As shown, the snap-fit ​​member 242 is disposed at the end of the housing 21 in the first direction z. The snap-fit ​​member 242 includes a first snap-fit ​​part 2421 and a second snap-fit ​​part 2422. The first snap-fit ​​part 2421 and the second snap-fit ​​part 2422 can move towards each other or away from each other. The first quick-connect member 241 is provided with a first slot 2412 and a second slot (not shown) symmetrically arranged. The openings of the first slot 2412 and the second slot are arranged opposite each other along the first direction z. The first snap-fit ​​part 2421 and the second snap-fit ​​part 2422 can move away from each other, so that the first snap-fit ​​part 2421 engages with the first slot 2412 and the second snap-fit ​​part 2422 engages with the second slot, thereby snapping the first quick-connect member 241 into the housing 21.

[0056] Therefore, when installing the scanning device 300 onto the housing 21, the first quick connector 241 is detachably connected to the scanning device 300 first, and then the first quick connector 241 is detachably connected to the snap-fit ​​connector 242, so as to improve the efficiency of installing the scanning device 300.

[0057] In some embodiments provided in this application, such as Figure 3 and Figure 5 As shown, a positioning groove 214 is provided at the end of the housing 21. The first quick-connect member 241 can be fitted into the positioning groove 214, and a portion of the snap-fit ​​member 242 extends into the positioning groove 214 to snap the first quick-connect member 241 into the positioning groove 214. Further, the positioning groove 214 is located at the end of the housing 21 in the first direction z, and the opening of the positioning groove 214 extends along the first direction z. The first quick-connect member 241 can be fitted into the positioning groove 214 to position the first quick-connect member 241.

[0058] The first latching part 2421 penetrates the inner wall of the positioning groove 214 along the second direction x, and the second latching part 2422 penetrates the other inner wall of the positioning groove 214 along the second direction x. One end of the first latching part 2421 is located inside the positioning groove 214, and the other end of the first latching part 2421 is located outside the housing 21 in the second direction x. The user can control the end of the first latching part 2421 located inside the positioning groove 214 by pushing the end of the first latching part 2421 located outside the housing 21. One end of the second latching part 2422 is located inside the positioning groove 214, and the other end of the second latching part 2422 is located outside the housing 21 in the second direction x. The user can control the end of the second latching part 2422 located inside the positioning groove 214 by pushing the end of the second latching part 2422 located outside the housing 21.

[0059] In some embodiments provided in this application, the handle 200 further includes a second connection component 25, such as Figure 2As shown, the second connecting component 25 and the first connecting component 24 are arranged along the third direction y, and the second connecting component 25 and the first connecting component 24 are located at the same end of the housing 21 in the first direction z.

[0060] like Figure 3 As shown, the second connecting assembly 25 includes a base 251 and a second quick-connect member 252. The base 251 is located at the end of the housing 21, and the second quick-connect member 252 is used to detachably connect to the host computer 500, and the second quick-connect member 252 is detachably connected to the base 251. Preferably, the second quick-connect member 252 is magnetically connected to the base 251 to improve the installation efficiency of the host computer 500; alternatively, the second quick-connect member 252 is connected to the base 251 by means of snap-fit, threaded connection, etc., which is not limited herein.

[0061] When installing the host computer 500 onto the housing 21, first connect the second quick-connect fitting 252 detachably to the host computer 500, and then connect the second quick-connect fitting 252 detachably to the base 251 to improve the installation efficiency of the host computer 500. Additionally, the host computer 500 can be clamped within the second quick-connect fitting 252 to improve the stability of the connection between the second quick-connect fitting 252 and the host computer 500.

[0062] In some embodiments provided in this application, the angle between the extension direction of the second quick connector 252 and the first direction z is an acute angle. Therefore, when the host computer 500 is installed on the second connection component 25, there is an angle between the host computer 500 and the part held by the user so that the user can observe the content displayed on the host computer 500.

[0063] In some embodiments provided in this application, such as Figure 2 As shown, the handle 200 also includes a signal transmission interface 23 and a power supply interface 22. The signal transmission interface 23 is electrically connected to the interface module 12 of the external device 100, and the power supply interface 22 is electrically connected to the battery module 14 of the external device 100. Preferably, the signal transmission interface 23 is a USB-A port, and the power supply interface 22 is a circular DC port. The signal transmission interface 23 is connected to the data transmission unit 121 in the external device 100, and the power supply interface 22 is connected to the power supply unit 122 in the external device 100. Both the signal transmission interface 23 and the power supply interface 22 are located on the side of the housing 21 in the first direction z near the first connecting component 24, so as to shorten the wiring length between either the signal transmission interface 23 or the power supply interface 22 and the scanning device 300.

[0064] When the input power of the scanning device 300 is less than the output power of the signal transmission interface 23, the scanning device 300 only needs to be electrically connected to the signal transmission interface 23. Figure 6As shown, this reduces the number of wires between the scanning device 300 and the external device 100, thereby reducing the probability of poor contact between the scanning device 300 and the external device 100; when the input power of the scanning device 300 is greater than the output power of the signal transmission interface 23, the scanning device 300 is electrically connected to the power supply interface 22 to supply power to the scanning device 300 through the power supply unit 122, as shown. Figure 7 As shown, it meets the power requirements of different models of scanning equipment 300.

[0065] Furthermore, such as Figure 3 As shown, the housing 21 has a hollow structure, including a connecting section 211, a grip section 212, and a base 213 connected in sequence along the first direction z. The interface module 12, battery module 14, and main control module 11 in the external device 100 are arranged in sequence along the first direction z, and are correspondingly arranged in the internal space of the connecting section 211, grip section 212, and base 213 in the housing 21, so as to maximize the use of the internal space of the handle 200 housing 21 and minimize the volume of the handle 200.

[0066] In some embodiments, the first connecting component 24 and the second connecting component 25 are located at the same end of the housing 21 in the first direction z, that is, both the first connecting component 24 and the second connecting component 25 are disposed on the connecting segment 211. Figure 3 The dimension in the xOy plane shown (i.e., the dimension of the projection plane in the vertical direction) is larger than that of the gripping segment 212. Figure 3 The dimensions in the xOy plane shown, base 213 in Figure 3 The dimension in the xOy plane shown is larger than that of the gripping segment 212. Figure 3 The dimensions in the xOy plane shown are such that the connecting segment 211 extends along the third direction y, and the base 213 extends along the third direction y to improve the stability of the handle 200 when placed on the horizontal plane and to support the scanning device.

[0067] In some embodiments, the surface of the grip section 212 is provided with a rubber sleeve 215. On the one hand, it can indicate the user's grip position and avoid interference with the transceiver module 13's transmission and reception of electromagnetic waves due to an incorrect grip position. On the other hand, the rubber sleeve 215 can increase the comfort of the grip. At the same time, due to the multi-layer design of the rubber sleeve 215 and the grip section 212, the heat insulation performance of the grip section 212 is increased, avoiding the feeling of burning due to excessive heat from the external device 100 inside the housing 21, thus improving the user experience.

[0068] In some embodiments, a button 28 is provided on the grip section 212 of the housing 21. The button 28 is electrically connected to the main control module 11 of the external device 100 so as to input control signals into the main control module 11 through the button 28 and input the control signals into the scanning device 300 through the interface module 12 to control the operation of the scanning device 300.

[0069] In some embodiments, the base 213 is provided with a charging interface 27 and a power switch 26. The power switch 26 is connected to the battery module 14 to control the power-on state of the external device 100. The charging interface 27 is electrically connected to the charging module 15 to charge the battery module 14 through the charging interface 27.

[0070] Furthermore, the base 213 is also equipped with a power indicator light and a status indicator light. The power indicator light is used to indicate the current remaining power of the handle, so as to remind the user to charge the handle in time when the power is low. Preferably, the power indicator light includes multiple LEDs, and different numbers of LEDs indicate different levels of power. The status indicator light is used to indicate the working status of the handle. The status indicator light is preferably a multi-color LED light, with different colors indicating different working states of the handle. For example, when the handle is normally connected to the scanning device, the status indicator light displays blue; when the handle is successfully wirelessly connected to the host computer, the status indicator light displays green; when the transceiver module in the handle is malfunctioning, it displays red; and when the handle is in the process of firmware upgrade, it displays yellow.

[0071] Furthermore, the base 213 houses the main control module 11 of the external device 100, which generates heat during operation. Therefore, a heat sink, preferably a metal component, is provided between the bottom surface of the base 213 and the main control module 11 to dissipate the heat generated by the main control module 11 through the base 213. This heat sink not only facilitates heat dissipation but also increases the weight of the base 213, improving the stability of the handle. Furthermore, the bottom surface of the base 213 may also be provided with an array of ventilation holes to expel hot air from inside the housing, maximizing the performance of the main control module 11, thereby reducing the power consumption of the handle and improving its performance.

[0072] The following is combined with Figure 6 and Figure 7 The scanning system provided in this application is described below. The scanning system includes the handle 200 as described in any of the above embodiments, and further includes a scanning device 300 detachably connected to the handle 200; and a connecting cable 400 connecting the scanning device 300 and the interface module 12. Figure 6 and Figure 7 As shown, the handle 200 provided in this application is wirelessly connected to the host computer of the scanning device 300 installed on the first connection component 24 through the transceiver module 13 of the external device 100 housed therein, so as to reduce the number of wires on the scanning device 300, thereby giving the scanning system provided in this application the advantage of high portability.

[0073] In addition, the scanning device 300 provided in this application is connected to the external device 100 via a connecting cable 400 to improve the data transmission speed between the scanning device 300 and the external device 100 and improve the communication quality between the scanning device 300 and the external device 100.

[0074] In some embodiments provided in this application, the scanning system further includes a host computer 500, which is detachably connected to the handle 200 and can communicate with the transceiver module 13. Figure 6 and Figure 7 As shown, the host computer 500 can be a portable terminal with wireless communication function such as a mobile phone, tablet computer, or laptop computer. The host computer 500 can be detachably connected to the handle 200 through the second connection component 25.

[0075] By mounting the host computer 500 on the handle 200, the distance between the host computer 500 and the transceiver module 13 is reduced, thereby reducing the communication delay between the transceiver module 13 and the host computer 500 and improving the communication efficiency between the external device 100 and the host computer 500.

[0076] Alternatively, the host computer can be a desktop terminal such as a desktop computer or an all-in-one computer that does not support wireless communication. In this case, the scanning system also includes a wireless communication module (such as a wireless network card), which can be plugged into the host computer. Figure 8 As shown, this enables wireless communication with the transceiver module 13 on the handle 200 to receive and display the scanning data from the scanning device 100 in real time. It should be understood that although the desktop terminal cannot be mounted on the handle 200, it can achieve wireless communication with the scanning device 100 through the handle 200, thereby improving the portability of the scanning device 100.

[0077] Furthermore, to achieve rapid wireless communication between the handle and the host computer, the scanning system also includes a marking pattern (such as a QR code) corresponding to the transceiver module 13 in the handle 200. This QR code can be placed on the handle 200 or displayed on the host computer. In one embodiment, the marking pattern can be placed on the handle 200, such as... Figure 9 As shown, when the transceiver module 13 in the handle 200 is in normal working condition, the host computer (such as a mobile phone, tablet, etc.) with scanning function can scan the logo pattern on the handle 200 to realize a fast wireless communication connection between the host computer and the external device, so that the host computer can receive the scanning data from the scanning device 100 and display it in real time.

[0078] In another embodiment, the scanned data from the scanning device 100 can be displayed on different types of host computers using a marker pattern, specifically, such as... Figure 10 and Figure 11As shown, different types of host computers include portable terminals with scanning functions and desktop terminals (such as mobile phones and desktop computers). The desktop terminal communicates wirelessly with the handle 200 to receive scanning data from the scanning device 100 for real-time display. At the same time, a logo pattern is displayed on the desktop terminal. The portable terminal with scanning function scans the logo pattern to realize wireless communication between the portable terminal and the desktop terminal, so as to synchronize the scanning data displayed on the desktop terminal to the portable terminal in real time, thereby realizing the display of scanning data between different types of host computers.

[0079] Furthermore, the portable terminal can be installed on the handle 200. When scanning an object using the scanning device 100 installed on the handle 200, the scanning effect of the scanning device 100 can be observed in real time through the portable terminal, so as to adjust the scanning posture of the scanning device 100 in real time and improve the scanning efficiency of the scanning device 100.

[0080] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
