Description

Technical Field

[0001] The utility model belongs to the field of handheld three-dimensional scanning, and in particular relates to a handheld three-dimensional scanner with a magnetic charging function. Background Art

[0002] With the rapid development of mobile devices and portable operating devices, the demand for the use of handheld operating devices is growing. However, traditional handheld operating devices usually need to be connected to the control terminal through a wired or wireless network to achieve the transmission of measurement data, such as a three-dimensional laser scanner, so the user needs to hold the scanning device and the control terminal with both hands, which brings the burden of two-handed operation to the user, especially in the operation scene where the user takes the elevator indoors and needs to pass through a closed door. This limits the flexibility and portability of the user's use of the device. In particular, in actual operation, the user not only needs to hold the scanning device and the control terminal at the same time, but also needs to adjust the angle and size of the mobile phone display content according to the scanning scene, which is very inconvenient; at the same time, during the operation, the computing demand for the control terminal will increase sharply, and the power will be consumed rapidly. However, it is difficult to charge during the operation. Equipping the mobile phone with external devices such as power banks as power supplements will increase the user's operating burden. Once the control terminal is exhausted, the three-dimensional laser scanner cannot be turned off through the control terminal, resulting in the inability to terminate the scanning operation, which seriously affects the user experience and work efficiency. In addition, for the sake of aesthetics, existing magnetic charging devices in other fields are specially designed with a wrapped shell on the outside, which causes the magnetic part to be relatively far away from the control terminal, affecting the magnetic effect, and the control terminal is easy to fall off, causing damage. Utility Model Content

By setting a magnetic suction module and a wireless charging transmitting coil module, an integrated connection between the control terminal and the 3D scanner and wireless charging of the control terminal are achieved.

[0004] The technical solution adopted by the utility model to solve the above technical problems is:

The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0028] See also Figure 1 , the embodiment of the present application provides a handheld three-dimensional scanner with a magnetic charging function, including a scanner body and a magnetic charging component, wherein the housing 3 of the scanner body has a mounting surface;

[0029] The magnetic charging component includes a magnetic module 1 and a wireless charging transmitting coil module 2, the magnetic module 1 includes a first magnetic part and a second magnetic part with an attraction effect, the first magnetic part of the magnetic module 1 and the wireless charging transmitting coil module 2 are installed on the mounting surface of the shell 3 and are on one side inside the shell, and the first magnetic part of the magnetic module 1 surrounds the periphery of the wireless charging transmitting coil module 2; the second magnetic part of the magnetic module 1 is installed on the back of the control terminal, and the control terminal is connected to the outside of the mounting surface of the scanner body shell 3 under the attraction of the first magnetic part and the second magnetic part in the magnetic module 1 to realize the connection between the control terminal and the scanner body, and the control terminal realizes the charging function with the cooperation of the wireless charging transmitting coil module 2 and the wireless charging receiving module inside the control terminal (which comes with it).

[0030] In this embodiment, a magnetic charging component is provided on the handheld three-dimensional scanner to achieve the fixation between the control terminal and the operating device and the on-demand charging of the control terminal; specifically, the control terminal is fixed on the three-dimensional scanner through the magnetic module 1, realizing the integrated connection between the control terminal and the three-dimensional scanner, solving the problem that the user needs to hold the two separately in the traditional device, which adds burden to the operation. The user only needs to operate the device with one hand to complete the scanning task, which greatly improves the convenience and flexibility of the operation; in addition, the control terminal and the three-dimensional scanner are connected by magnetic suction, which is convenient for the quick connection and disassembly of the two, and the structural form of the three-dimensional scanner itself is not required, and only the installation surface is provided. At the same time, the first magnetic suction part of the magnetic module 1 and the wireless charging transmitting coil module 2 are arranged inside the installation surface of the three-dimensional scanner, ensuring the aesthetics of the three-dimensional scanner. In addition, in this embodiment, the wireless charging transmitting coil module 2 is arranged on the three-dimensional scanner, and is used in conjunction with the wireless charging receiving module inside the control terminal to realize the wireless charging of the control terminal, solving the problem that the control terminal needs to constantly replace the device battery during use, and improving the operation efficiency and operation time.

[0031] It should be noted that the control terminal in this embodiment includes but is not limited to a mobile phone or a tablet, and may also be other portable electronic devices with a screen and a wireless charging receiving module that can realize data transmission.

[0032] Furthermore, in order to ensure the stability of the connection between the scanner body and the control terminal, the first magnetic attraction part of the magnetic attraction module 1 in this embodiment is an annular structure, and the wireless charging transmitting coil module 2 is arranged in the first magnetic attraction part of the magnetic attraction module 1; specifically, the magnetic attraction module 1 is composed of an annular magnet fixing part 1-1 and a plurality of magnet units 1-2; the magnet fixing part 1-1 is an annular metal sheet, and the specific material is stainless steel. The plurality of magnet units 1-2 are arranged on one side surface of the magnet fixing part 1-1 along the circumferential direction of the magnet fixing part 1-1, and are attracted and connected to the magnet fixing part 1-1 to realize the shaping of the plurality of magnet units 1-2.

[0033] Among them, in order to make the routing of the wireless charging transmitting coil module more regular, an opening is opened on the first magnetic attraction part in this embodiment, and preferably forms a "C"-shaped structure or a semi-annular structure; accordingly, the magnet fixing part 1-1 is a "C"-shaped metal sheet or a semi-annular metal sheet.

[0034] Among them, each magnet unit 1-2 in this embodiment is an arc-shaped block structure; specifically, the magnet unit 1-2 is an arc-shaped magnet with a thickness of 2.5mm, an inner diameter of 46mm, an outer diameter of 54mm, and a circumferential angle of 20°. The two adjacent magnet units 1-2 fit tightly to ensure that no gaps are generated; in this embodiment, 15 magnet units 1-2 are preferably connected in sequence and assembled into a "C"-shaped magnetic suction module 1 with a circumferential angle of 300°.

[0035] It should be noted that the second magnetic attraction part of the magnetic attraction module 1 in this embodiment is a circular ring structure, and is basically the same as the composition structure and size of the first magnetic attraction part of the magnetic attraction module 1, that is, the second magnetic attraction part of the magnetic attraction module 1 is composed of a circular ring fixing part and a plurality of magnet units; in this embodiment, the magnetic attraction module 1 is designed as a ring structure, on the one hand, the distribution range of the magnetic attraction points can be increased to increase the connection area between the three-dimensional scanner and the control terminal, thereby ensuring the stability of the connection between the three-dimensional scanner and the control terminal; on the other hand, the wireless charging transmitting coil module 2 can be arranged inside the magnetic attraction module 1 to ensure that the wireless charging transmitting coil module 2 can be completely covered with the charging receiving module of the control terminal, thereby improving the charging efficiency.

[0036] In this embodiment, the magnetic module 1 is provided in the form of an arc-shaped magnet block, rather than an integrated ring magnet, which can improve the utilization rate of the magnet and reduce the manufacturing cost. In addition, an opening is provided on one side of the magnetic module 1 to facilitate connecting the power cord of the wireless charging transmitting coil module 2 to the inside of the device, making the wiring more regular.

[0037] Furthermore, in order to increase the attraction force between the first magnetic attraction part and the second magnetic attraction part of the magnetic attraction module 1, when the thickness of the shell 3 is greater than 0.4mm, a groove 3-1 matching the first magnetic attraction part is processed on the mounting surface of the shell 3 and the side facing the inside in this embodiment, and when the first magnetic attraction part is a "C"-shaped structure, the groove 3-1 is "C"-shaped or annular, and when the first magnetic attraction part is a semi-annular structure, the groove 3-1 is semi-annular, "C"-shaped or annular, so as to ensure that the groove 3-1 can completely accommodate the first magnetic attraction part; wherein the wall thickness of the groove 3-1 is 0.4mm, so that the distance between the first magnetic attraction part and the second magnetic attraction part of the magnetic attraction module 1 is shortened to 0.4mm, thereby reducing the distance between the two and improving the attraction force.

[0038] It should be noted that the wireless charging transmitting coil module 2 is fixed in the area enclosed by the groove 3-1. In addition, the inner diameter of the groove 3-1 in the width direction is larger than the width of the magnet unit 1-2 to facilitate the installation of the first magnetic attraction portion of the magnetic attraction module 1.

[0039] Furthermore, the wireless charging transmitting coil module 2 includes an enameled wire coil 2-1, a magnetic isolation sheet 2-2, a power supply and a control switch.

Specifically, the connection can be made by using 3M adhesive. The enameled wire coil 2-1 is connected to the power supply through a power supply circuit, and the control switch is connected to the power supply through a control circuit to drive the enameled wire coil 2-1 to be powered on and off.

[0040] In this embodiment, when the control terminal is connected to the three-dimensional scanner, there is no need for real-time charging, so the charging and power-off of the control terminal can be achieved through the control switch. The power supply circuit and the control circuit are both arranged on the carrier board of the computing device inside the three-dimensional scanner. In addition, it should be noted that the control switch in this embodiment is only used to control the wireless charging transmitting coil module 2, and does not have a control function for the power consumption of the three-dimensional scanner itself.

[0041] The enameled wire coil 2 - 1 is a ring coil formed by winding enameled wire with an outer diameter of 42 mm and an inner diameter of 20 mm to adapt to the size of the control terminal.

[0042] Among them, the magnetic isolation plate 2-2 is an annular metal plate, and the specific material is iron; in addition, the thickness of the magnetic isolation plate 2-2 is 0.5~1mm, the outer diameter of the magnetic isolation plate 2-2 is equal to the outer diameter of the enameled wire coil 2-1, and the inner diameter of the magnetic isolation plate 2-2 is smaller than the inner diameter of the enameled wire coil 2-1.

[0043] In this embodiment, the design of the material and size of the magnetic isolation sheet 2-2 achieves a comprehensive magnetic isolation effect on the enameled wire coil 2-1.
