Description

A handheld 3D scanner with magnetic charging function 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 handheld operating devices is growing. However, traditional handheld operating devices, such as 3D laser scanners, typically require a wired or wireless connection to a control terminal to transmit measurement data. This requires users to hold both the scanning device and the control terminal in their hands, placing a burden on the user's two hands. This is particularly inconvenient when working indoors in elevators or through closed doors, limiting the user's flexibility and portability. In practice, users not only need to hold both the scanning device and the control terminal simultaneously, but also need to adjust the angle and size of the mobile phone display according to the scanning scenario, which is very inconvenient. Furthermore, the computing demands on the control terminal increase dramatically during operation, rapidly depleting the battery. However, charging during operation is difficult, and using an external device such as a power bank to supplement the phone's power supply increases the user's operational burden. Once the control terminal runs out of power, the 3D laser scanner cannot be shut down via the control terminal, resulting in an inability to terminate the scanning operation, seriously affecting 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.

[0031] In the embodiment, the magnetic attraction charging assembly is arranged on the handheld three-dimensional scanner to realize 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 attraction module 1, which realizes the integrated connection of the control terminal and the three-dimensional scanner, solves the problem that the user needs to hold both in the traditional device, increases the burden of operation, and the user can complete the scanning task by operating the device with one hand, which greatly improves the convenience and flexibility of operation. In addition, the control terminal and the three-dimensional scanner are connected in a magnetic attraction mode, which facilitates the quick connection and disassembly of the two, and has little requirement on the structure form of the three-dimensional scanner, only provides the mounting surface, and at the same time, the first magnetic attraction part of the magnetic attraction module 1 and the wireless charging transmitting coil module 2 are arranged inside the mounting surface of the three-dimensional scanner, which ensures the aesthetics of the three-dimensional scanner. In addition, the wireless charging transmitting coil module 2 is arranged on the three-dimensional scanner in the embodiment, which is used in combination with the wireless charging receiving module inside the control terminal, realizes the wireless charging of the control terminal, solves the problem that the control terminal needs to replace the device battery constantly during use, and improves the operation efficiency and operation time.

[0032] It should be noted that the control terminal in the embodiment includes but is not limited to a mobile phone or a tablet, and can also be other portable electronic devices with a screen and a wireless charging receiving module that can realize data transmission.

[0033] Further, 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 the embodiment is in a ring 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 a ring-shaped magnet fixing part 1-1 and a plurality of magnet units 1-2. The magnet fixing part 1-1 is a ring-shaped metal sheet, specifically made of 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, so as to fix the plurality of magnet units 1-2.

[0034] In order to make the wire of the wireless charging transmitting coil module more regular, an opening is formed on the first magnetic attraction part in the embodiment, and preferably a "C" shape structure or a semi-ring structure is formed. Correspondingly, the magnet fixing part 1-1 is a "C" shaped metal sheet or a semi-ring metal sheet.

[0035] In the embodiment, each magnet unit 1-2 is in an arc block structure. Specifically, the magnet unit 1-2 is a circular arc magnet with a thickness of 2.5 mm, an inner diameter of 46 mm, an outer diameter of 54 mm, and a circumferential angle of 20°. The adjacent two magnet units 1-2 are tightly fitted to ensure that no gap is generated. In the embodiment, preferably, 15 magnet units 1-2 are sequentially connected and spliced into a "C" shaped magnetic attraction module 1 with a circumferential angle of 300°.

[0036] It should be noted that the second magnetic attraction part of the magnetic attraction module 1 in the embodiment is in a circular ring structure and has substantially the same structure and size as 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 the embodiment, the magnetic attraction module 1 is designed in a ring structure, which can increase the range of magnetic attraction point distribution, increase the area of connection between the three-dimensional scanner and the control terminal, and ensure 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, so that the wireless charging transmitting coil module 2 can be completely covered by the charging receiving module of the control terminal, and the charging efficiency is improved.

[0037] In the embodiment, the magnetic attraction module 1 is set in the form of an arc-shaped magnet block instead of an integral ring-shaped magnet, which can improve the utilization rate of the magnet and reduce the manufacturing cost. In addition, an opening is formed on one side of the magnetic attraction module 1, which is convenient for connecting the power line of the wireless charging transmitting coil module 2 to the inside of the equipment, so that the wire is more regular.

[0038] Further, in order to increase the attraction force of 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 0.4 mm, a groove 3-1 matched with the first magnetic attraction part is processed on the mounting surface of the shell 3 and towards the inside. When the first magnetic attraction part is in a "C" shape, the groove 3-1 is in a "C" shape or a ring shape. When the first magnetic attraction part is in a semi-ring shape, the groove 3-1 is in a semi-ring shape, a "C" shape or a ring shape, so as to ensure that the groove 3-1 can completely accommodate the first magnetic attraction part. The wall thickness at the groove 3-1 is 0.4 mm, 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 0.4 mm, the distance between them is reduced, and the attraction force is improved.

[0039] 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 greater than the width of the magnet unit 1-2, so as to facilitate the installation of the first magnetic attraction part of the magnetic attraction module 1.

The enameled wire coil 2-1 is connected with the power supply through a power supply circuit, and the control switch is connected with the power supply through a control circuit, so as to drive the power-on and power-off of the enameled wire coil 2-1.

[0041] In the embodiment, the control terminal is connected with the three-dimensional scanner without real-time charging, so that the charging and power-off of the control terminal can be realized through the control switch. In addition, the power supply circuit and the control circuit are arranged on the bearing plate of the internal computing device of the three-dimensional scanner. It should be noted that the control switch in the embodiment is only used for the control of the wireless charging transmitting coil module 2, and does not have the control function for the power consumption of the three-dimensional scanner itself.

[0042] The enameled wire coil 2-1 is a ring-shaped coil with an outer diameter of 42 mm and an inner diameter of 20 mm, which is wound by enameled wire, so as to adapt to the size of the control terminal.

[0043] The magnetic shielding sheet 2-2 is a ring-shaped metal sheet, and the specific material is iron. In addition, the thickness of the magnetic shielding sheet 2-2 is 0.5-1 mm, the outer diameter size of the magnetic shielding sheet 2-2 is equal to the outer diameter size of the enameled wire coil 2-1, and the inner diameter size of the magnetic shielding sheet 2-2 is smaller than the inner diameter size of the enameled wire coil 2-1.

[0044] In the embodiment, the design of the material and size of the magnetic shielding sheet 2-2 has a comprehensive magnetic shielding effect on the enameled wire coil 2-1.
