DETAILED DESCRIPTION

[0018] The embodiments of the utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the utility model, and cannot be understood as limiting the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0019] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "circumferential", "radial" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0020] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0021] In the related art, 3D scanning equipment is connected to terminal devices such as computers and mobile phones through USB data cables to transmit the collected image data to the terminal devices, and complete the modeling on the terminal devices. However, the real-time data transmission between the 3D scanning equipment and the terminal devices is limited by the length of the data cable. The USB data cable cannot be very long. Therefore, if the user needs to move and adjust the device over a large range during the scanning process, the operation is very inconvenient, which can easily cause the connection between the data cable and the USB interface to loosen, resulting in abnormal shutdown and disconnection. After the connection is restored, it is necessary to rescan, which is difficult to meet user needs.

[0022] In order to meet the needs of users for convenient operation, quick storage and outdoor portability, handheld 3D scanning devices that can carry mobile phones for real-time data pairing and are equipped with rechargeable batteries for self-powered power have emerged. However, in the related art, handheld scanners that can carry mobile phones generally connect the handheld 3D scanning device and the mobile phone through a USB3.0 data cable to achieve real-time data transmission, and the power storage and power supply of the mobile phone itself are very limited. Therefore, the power supply of the handheld 3D scanning device needs to be provided by another battery and power cord.

[0023] It can be seen that although portable handheld 3D scanning devices that can be loaded with mobile phones and charging handles can solve the pain points of computer data cable connection to a certain extent, due to the limited transmission rate of the data connection interface of many mobile phones, they cannot meet the data transmission needs of 3D scanning devices with large data volumes and high speeds. Not only that, the interfaces of different types of mobile phones on the market may be inconsistent, and the data interfaces of some manufacturers have protection authentication mechanisms, making 3D scanning devices unsuitable for many occasions. In addition, in addition to the data cable, the 3D scanning device also requires a separate power cable for power supply. The increase in wires makes the wiring of the 3D scanning device more messy during use, making it difficult to meet user needs.

[0024] Embodiment 1:

[0025] In order to solve the above problems in the related art, the present application provides a 3D scanning device.

[0026] like Figure 1 As shown, in this embodiment, a three-dimensional scanning system is provided. The three-dimensional scanning system may include a 3D scanning device 100 and a terminal device 200. The 3D scanning device 100 and the terminal device 200 may communicate wirelessly via WiFi. The 3D scanning device 100 is used to scan the target object to obtain scanning data such as two-dimensional data and three-dimensional data. The terminal device 200 is used to receive the scanning data and perform three-dimensional reconstruction based on the scanning data. The terminal device 200 may be a mobile phone, a tablet, a computer, etc., which is not limited here. A client may be installed on the terminal device 200, and a scanning instruction may be issued to the 3D scanning device 100 and scanning data may be received, and relevant processing may be performed based on the scanning data. The scanning data may include color image data, infrared image data, depth image data, etc.

[0027] Combination Figures 2 to 4 , the 3D scanning device 100 includes a handle 1 and a 3D scanner 2 mounted on the handle 1, the handle 1 includes a housing 15, a circuit board assembly 10 disposed in the housing 15, and a battery 14 electrically connected to the circuit board assembly 10, and the 3D scanner 2 is electrically connected to the circuit board assembly 10. The circuit board assembly 10 includes a main control module 101, a power management module 102, and a WiFi transceiver module 13; the power management module 102 is electrically connected to the battery 14, the main control module 101, the WiFi transceiver module 13, and the 3D scanner 2 to supply power to the main control module 101, the WiFi transceiver module 13, and the 3D scanner 2; the WiFi transceiver module 13 is used to communicate with the terminal device 200 via WiFi; the main control module 101 is connected to the 3D scanner 2 and the WiFi transceiver module 13 to realize data transmission between the 3D scanner 2 and the WiFi transceiver module 13.

[0028] Since the 3D scanner 2 is not a communication master device, its own multimedia and depth data streams cannot be directly sent to the terminal device 200 through the WiFi transceiver module 13, nor can it directly receive the instructions issued by the terminal device 200 through the WiFi transceiver module 13. It is necessary to initiate its communication through the main control module 101 as the communication master device. The streaming media data of the 3D scanner 2 is transmitted to the main control module 101 through the data line. The main control module 101 undergoes a series of logical processing and protocol conversion, and then outputs the streaming media data to the WiFi transceiver module 13 through the TCP protocol, RTSP protocol and other network data protocols. The WiFi transceiver module 13 transmits the streaming media data to the terminal device 200 through WiFi. The process of the terminal device 200 sending the scanning instruction to the 3D scanner 2 is in the opposite order, which will not be repeated here. Among them, the power supply logic of the 3D scanning device is as follows: the battery 14 supplies power to the power management module 102, and the power management module 102 can supply power to the main control module 101 and the WiFi transceiver module 13 respectively, and can supply power to the 3D scanner 2 through the data line, thereby ensuring the normal operation of each module.

[0029] The main control module 101, the power management module 102 and the WiFi transceiver module 13 may be corresponding circuits composed of corresponding chips and various electronic components, and may be arranged on corresponding circuit boards. For example, the main control module 101 is essentially a main control circuit arranged on the circuit board assembly 10, which may include a main control chip and related control circuits; the power management module 102 is essentially a power management circuit arranged on the circuit board assembly 10, which may include a power management chip, a voltage conversion chip, etc.; the WiFi transceiver module 13 is essentially a WiFi transceiver circuit arranged on the circuit board assembly 10, which may include a WiFi antenna.

[0030] The main control module 101 is mainly used for functions such as logic processing and protocol conversion. For example, the main control module 101 can receive and process the scan data collected by the 3D scanner 2 and transmit the processed data to the WiFi transceiver module 13, and receive and process the command data sent by the WiFi transceiver module 13 and transmit the processed data to the 3D scanner 2. The power board 12 can be provided with relevant circuits to control the battery 14 to power the main control module 101, the WiFi transceiver module 13 and the 3D scanner 2, without the need to power the 3D scanner 2 through the terminal device or an external power supply. The WiFi transceiver module 13 is used to transmit WiFi signals, so that the 3D scanning device 100 can communicate wirelessly with the terminal device 200, with high data transmission efficiency, and will not be limited by the protection authentication mechanism of different terminal devices 200.

[0031] Therefore, the 3D scanning device of the present application is provided with a battery 14 and a power management module 102 in the handle 1, which can directly power the 3D scanner 2, the main control module 101 and the WiFi transceiver module 13, making it more convenient to use. The WiFi transceiver module 13 is integrated in the handle 1, so that the 3D scanning device 100 can communicate wirelessly with the terminal device 200, and will not be limited by the data cable during scanning, so scanning is more convenient, and the data transmission rate is high, the scanning efficiency is high, and it is not limited by the interface protection authentication mechanism of the terminal device 200. Compared with the 3D scanning device that realizes WiFi transceiver through an external router, the 3D scanning device of the present application is smaller in size.

[0032] In some embodiments, the housing 15 may be a plastic housing or a metal housing, etc., which is not limited herein. Figure 2-5 As shown, the housing 15 includes a first housing 151 and a second housing 152. The first housing 151 and the second housing 152 are enclosed to form a receiving cavity, and the circuit board assembly 10 and the battery 14 are received in the receiving cavity. In some embodiments, a mounting portion is provided at the top of the housing 15, and a connecting portion that matches the mounting portion is provided at the bottom of the 3D scanner 2. The mounting portion and the connecting portion are connected to each other so that the 3D scanner 2 can be installed on the top of the housing 15. In one embodiment, the mounting portion may include a hand screw 153 provided at the top of the housing 15, and the connecting portion may include a first threaded hole that matches the position and shape of the hand screw 153. The hand screw 153 can be screwed together with the first threaded hole to fix the 3D scanner 2 on the handle 1.

[0033] The top of the first shell 151 and the second shell 152 form a screw installation groove together, and the hand screw 153 is limited in the screw installation groove and exposed, so that the user can manually tighten it. The housing 15 also includes a bearing plate 154 installed on the top of the first shell 151 and the second shell 152 and covering the installation groove. The bearing plate 154 can carry the 3D scanner 2 to ensure the stability of the 3D scanner 2. The bearing plate 154 can be provided with a through hole, and the hand screw 153 passes through the through hole and can be freely screwed in the screw installation groove. Because the bearing plate 154 is stuck, the hand screw 153 will not fall off or be taken out. The rod of the hand screw 153 can be screwed and fixed with the first threaded hole at the bottom of the 3D scanner 2, thereby ensuring the installation stability between the 3D scanner 2 and the handle 1, and the 3D scanner 2 and the handle 1 are more convenient to disassemble and assemble. Of course, the mounting portion and the connecting portion can also be other matching structures, such as a cold shoe seat and a cold shoe groove.

[0034] In some embodiments, the circuit board assembly 10 includes a main control board 11 and a power board 12.

The 3D scanning device also includes a USB data cable 5, which can be connected to the 3D scanner 2 via the USB data cable 5. The current of the battery 14 can flow to the main control board 11 through the power board 12. The power management module 102 can reasonably distribute the required voltage of each module on the main control board 11 and the 3D scanner 2, and respectively power the main control module 101 and the WiFi transceiver module 13 of the handle 1, and power the 3D scanner 2 via USB.

[0035] In some embodiments, Figure 4 and Figure 5 As shown, the WiFi transceiver module 13 includes a WiFi indication panel 131, a WiFi antenna 132, a WiFi switch 133 and a WiFi indicator light 134. The outer side of the housing 15 has a first installation area. The WiFi indication panel 131 is arranged in the first installation area. The WiFi indication panel 131 is used to indicate the position of the WiFi antenna 132. The WiFi antenna 132 can be electrically connected to the main control board 11 through a coaxial line. The WiFi switch 133 and the WiFi indicator light 134 are arranged on the main control board 11 and are electrically connected to the main control board 11. The WiFi switch 133 is used to switch the power of the WiFi antenna 132. The WiFi indicator light 134 is used to indicate the working state of the WiFi transceiver module 13, such as switch, abnormality, etc. For example, when the WiFi transceiver module 13 is in the states of opening, closing, waiting to be connected and connected, the WiFi indicator light 134 can display different colors. The first installation area is provided with a first through hole corresponding to the WiFi switch 133 and the WiFi indicator light 134 to respectively expose the WiFi switch 133 and the WiFi indicator light 134.

[0038] In some embodiments, the handle 1 also includes a transmission button 121, which can be installed in the second through hole and opposite to the power switch 123, and is located between the power indication panel 122 and the power switch 123. The user can press the power indication panel 122 to press the transmission button 121, thereby turning on the power switch 123 and turning on the battery 14 and the power board 12.

[0039] In some embodiments, the housing 15 further includes a soft rubber cover 155, which can be mounted on the outside of the first housing 151 and the second housing 152.

[0040] The soft rubber sleeve 155 can be an integrated structure wrapped around the outer circumference of the shell 15, or it can be two, and the two soft rubber sleeves 155 can be respectively set on both sides of the shell 15, for example, the two silicone sleeves 155 can be respectively fixed on the outside of the first shell 151 and the second shell 152, or one silicone sleeve 155 is fixed on one side of the first shell 151 and the second shell 152, and the other silicone sleeve 155 is fixed on the other side of the first shell 151 and the second shell 152. For example, the outside of the first shell 151 and the second shell 152 is provided with a mounting groove that matches the shape of the corresponding soft rubber sleeve 155, and the soft rubber sleeve 155 can be attached to the corresponding installation of the first shell 151 and the second shell 152 with glue, and the fixing effect is good.

The heat sink 16 can be fixed to the main control board 11 by screw fastening, and the battery 14 and the power board 12 can be fixed on the side of the heat sink 16 away from the main control board 11, so that the heat sink 16 can dissipate heat for the main control board 11, the battery 14 and the power board at the same time, and the heat dissipation efficiency is high.

In some embodiments, the heat-conducting bracket 17 includes a base 171 fixed to the bottom side of the shell 15 and connected to the heat sink 16, and at least three legs 172 hinged on the base 171. The base 171 can be fixed to the bottom of the first shell 151 and the bottom of the second shell 152 by screws, respectively. The base 171 has a contact portion that is in thermal contact with the heat sink 16, so that the heat sink 16 can conduct heat to the heat-conducting bracket 17 through the contact portion, and finally release the heat to the environment through radiation and convection, thereby reducing the temperature of the shell 15, the inside of the shell 15, and the soft rubber sleeve 155, reducing the temperature feel of the hand-held part, which is conducive to improving the hand-held experience of the user.

[0043] The number of legs 172 can be three, four, five, etc. The embodiment of the present application is described by taking three legs 172 as an example.

The 3D scanner 2 of this application is described as a structured light binocular camera. The 3D scanner 2 may include a housing 21 and a laser emission module 22, two infrared imaging modules 23 and a depth calculation chip (not shown in the figure) arranged in the housing. The laser emission module 22 is used to emit a laser beam toward the target object, and the two infrared imaging modules 23 are used to collect the laser beam reflected back by the target object and generate an infrared image. In some embodiments, the 3D scanner 2 may also not include a depth calculation chip, and the depth is calculated by an external device based on the infrared image (for example, a mobile terminal is used to calculate the depth based on the infrared image). In some embodiments, the 3D scanner 2 may also include a color imaging module 24 for collecting a color image of the target object to add texture information when performing three-dimensional modeling based on the color image. When the 3D scanner is a scanner of other types, the corresponding components may be different.

[0045] In some embodiments, Figure 2 and Figure 3As shown, the 3D scanning device 100 further includes a shaft assembly 3, the two ends of which can be connected to the handle 1 and the 3D scanner 2 respectively, so that the imaging angle of the 3D scanner 2 can be adjusted. In one embodiment, a first cold shoe seat 21 is provided at the bottom of the 3D scanner 2, one end of the shaft assembly 3 is provided with a first cold shoe slot 31 adapted to the first cold shoe seat 21, and the other end is provided with a matching portion for matching with the top mounting portion of the handle 1, for example, Figure 2 and Figure 3 As shown, the mounting portion at the top of the handle 1 is a hand screw 153, and the matching portion at the other end of the shaft assembly 3 can be a second threaded hole. The first cold shoe slot 31 cooperates with the first cold shoe seat 21, so that the 3D scanner 2 and the shaft assembly 3 are fast-released and fixed. The 3D scanner 2 can be rotated by the shaft assembly 3 to change the imaging angle of the 3D scanner 2, so that the 3D scanning device can flexibly collect data in different directions. The shaft assembly 3 and the 3D scanner 2 can be fixed by plugging and unplugging the first cold shoe seat 21 and the first cold shoe slot 31, which is convenient for disassembly and assembly. And when there is no need to rotate the 3D scanner 2, the 3D scanner 2 can also be directly mounted on the top of the housing 15 by the matching fixation between the hand screw 153 and the first threaded hole, which is more convenient to use. Of course, the shaft assembly 3 can also be connected to the handle 1 and the 3D scanner 2 by other means such as snap-on connection, which is not limited here. For example, the shaft assembly 3 can also be connected by means of a cold shoe seat and a cold shoe slot.

[0046] In some embodiments, the 3D scanning device may further include a clamping assembly 4, which is used to clamp the terminal device 200. The clamping assembly 4 may include a fixed seat and a movable clamping claw, and the movable clamping claw may be movably mounted on the fixed seat so that the clamping space size of the clamping assembly 4 is adjustable. A second cold shoe seat 32 is provided at the bottom of the shaft assembly 3, and a second cold shoe slot 41 is provided at one end of the clamping assembly 4, and a third threaded hole for tightening with a hand screw 153 is provided at the other end; the second cold shoe slot 41 may be clamped and fixed with the first cold shoe seat 21, or used to be clamped and fixed with the second cold shoe seat 32. The clamping assembly 4 can be used to fix a small terminal device such as a mobile phone or a tablet, which is more convenient for users to use in handheld occasions. The clamping assembly 4 has a second cold shoe slot 41, which can be plugged in and out with the first cold shoe seat 21, or plugged in and out with the second cold shoe seat 32, that is, the user can flexibly install the shaft assembly 3 and / or the clamping assembly 4 between the 3D scanner 2 and the handle 1 according to actual use requirements, and can quickly switch the working mode of the 3D scanning device, thereby improving the convenience of operation of the 3D scanning device and the adaptability to different scenarios. In other embodiments, the clamping assembly 4 can also be connected to the shaft assembly 3 and the handle 1 using other matching structures.
