[0037] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.
[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.
[0039] Taking a handheld oral scanner as an example, in order to make it more convenient for the operator to use, the size of the scanner main body is getting smaller and smaller in the existing technical solutions. At the same time, the problem is that in the existing solutions, the first wireless charging coil is a planar structure, while the inner wall of the accommodating cavity of the scanner main body shell 101 is generally an arc structure, which easily leads to a waste of some space. Figure 1 A schematic diagram of the structure of a scanner host in a related solution is shown. Figure 1 The structure shown in the figure shows that Figure 1 The space K1 filled with the middle shadow is separated from other spaces by the first wireless charging coil 102 . However, since the space K1 is small, no other components can be arranged therein, so the space is wasted.
[0040] Based on the above technical problems, this application provides a scanner host, such as Figure 2 A schematic diagram of the structure of a scanner host provided in an embodiment of the present application, the scanner host includes:
[0041] The housing 101 is provided with a receiving cavity.
[0042] The first wireless charging coil 102 is disposed in the accommodating cavity, and the shape of the first wireless charging coil 102 matches the shape of the inner wall of the accommodating cavity.
[0043] It should be noted that, for the sake of simplicity, all drawings in the embodiments of the present application briefly illustrate or indicate necessary structures, and other structures not illustrated do not mean that the structures in the embodiments of the present application are not included.
[0044] The first wireless charging coil 102 in the embodiment of the present application can be a battery in the scanner host ( Figure 2 The shape of the first wireless charging coil 102 in the embodiment of the present application matches the shape of the inner wall of the accommodating cavity, which means that the shape of the first wireless charging coil 102 is the same as or similar to the shape of the inner wall of the accommodating cavity, and the minimum distance between the first wireless charging coil 102 and the inner wall of the accommodating cavity at any position is the same, and the minimum distance can be greater than zero or equal to zero. Figure 2The example diagram illustrates an arc-shaped inner wall of the accommodating cavity. Accordingly, the first wireless charging coil 102 can also be an arc-shaped structure (curved coil). The minimum distance between the first wireless charging coil 102 and the inner wall of the accommodating cavity at any position is a. Due to the limited space inside the scanner host, the inductance and coupling surface of the first wireless charging coil 102 can be increased, thereby transmitting greater wireless charging power. A corresponding mounting bracket or the like can be provided on the inner wall of the accommodating cavity to secure the first wireless charging coil 102, which will not be further described here.
[0045] Therefore, the embodiment of the present application can reduce the space between the first wireless charging coil 102 and the inner wall of the accommodating cavity through the above technical solution. Correspondingly, the other space in the accommodating cavity is increased. Therefore, the embodiment of the present application can alleviate the problem of space waste and is conducive to the miniaturization of the scanner host.
[0046] Figure 3 A schematic diagram of another scanner host structure provided in an embodiment of the present application. In some embodiments, the first wireless charging coil 102 is attached to the inner wall of the accommodating cavity;
[0047] The first wireless charging coil 102 and the inner wall of the accommodating cavity are both arc-shaped structures.
[0048] Specifically, the first wireless charging coil 102 in the embodiment of the present application can be fixed to the inner wall of the accommodating cavity using an adhesive. Based on the above solution, the first wireless charging coil 102 in the embodiment of the present application can be directly attached to the inner wall of the accommodating cavity, that is, the distance between the first wireless charging coil and the inner wall of the accommodating cavity is zero. This can greatly reduce the space inside the accommodating cavity and facilitate the miniaturization of the scanner host.
[0049] Figure 4 This is another schematic diagram of a scanner host structure provided by an embodiment of the present application. In some embodiments, the scanner host further includes a first positioning member 103, which is used to align the first wireless charging coil 102 with the second wireless charging coil in the scanner base.
[0050] When charging the scanner host via the first wireless charging coil 102, it is necessary to align the first wireless charging coil 102 with the second wireless charging coil in the scanner host. This allows the first wireless charging coil 102 to induct the second wireless charging coil, causing a change in magnetic flux, which in turn generates a current in the first wireless charging coil 102, thereby charging the scanner host. If the first wireless charging coil 102 is not aligned with the second wireless charging coil, charging will not proceed, or the charging effect will be poor.
[0051] Specifically, the first positioning member 103 may be a positioning pin or the like. In the embodiment of the present application, the first wireless charging coil 102 and the second wireless charging coil may be aligned based on the above technical solution, thereby avoiding the problem of the scanner host being unable to charge due to user negligence, thereby improving the convenience of use.
[0052] In some embodiments, the first wireless charging coil 102 may be an RX coil, and the second wireless charging coil may be a TX coil. The scanner host may also include a first wireless charging control component, and the scanner base may include a second wireless charging control component and an H-bridge drive circuit. The first wireless charging control component is electrically connected to the first wireless charging coil, the second wireless charging control component is electrically connected to the H-bridge drive circuit, and the H-bridge drive circuit is electrically connected to the second wireless charging coil. During the charging process, the second wireless charging control component can control the H-bridge drive circuit to drive the TX coil to generate an alternating magnetic field. The RX coil and the TX coil couple with each other to generate a corresponding induced magnetic field. The first wireless charging control component can convert the energy of the induced magnetic field generated by the TX coil into a DC power supply to charge the battery in the scanner host.
[0053] In some embodiments, the first positioning member 103 includes a first permanent magnet.
[0054] Specifically, the first positioning member 103 can also be a first permanent magnet, and the scanner base can be provided with a corresponding element capable of generating a magnetic force with the first permanent magnet, such as a metal block. Thus, while the scanner is charging, the operator can naturally place the scanner in a specific position due to the magnetic attraction of the first permanent magnet, without the need for deliberate alignment, further enhancing ease of use.
[0055] Figure 5 The schematic diagram of the circuit structure of a scanner host provided in an embodiment of the present application is shown in FIG. In some embodiments, the scanner host further includes a first control component 104 and a wireless network component 105 .
[0056] The first control component 104 is electrically connected between the first wireless charging coil 102 and the wireless network component 105. The first control component 104 is used to demodulate the modulated signal received by the first wireless charging coil 102, generate identity information, and modify the configuration information of the wireless network component 105 based on the identity information.
[0057] The wireless network component 105 is used to wirelessly interconnect with the scanner base based on the identity information.
[0058] After scanning an object, the scanner host generally needs to be wirelessly connected to the scanner base and transmit the relevant data information obtained from the scan to the scanner base. The scanner base then transmits the data information to the PC for relevant processing. In the process of interconnecting the scanner host and the scanner base, it is generally necessary to verify the identity information. The identity information can include the SSID and password. Only when the identity information is verified correctly can the scanner host and the scanner base be interconnected. In the existing technical solutions, the identity information is generally burned directly in the scanner host, or the identity information is verified by scanning a QR code. For the method of directly burning the identity information, the identity information cannot be modified and is not conducive to maintenance. For the method of scanning the QR code, the camera pixel of the scanner host is low, the scanning format is small, the scanning recognition rate is not high, and the scanning speed is slow, and the experience is poor.
[0059] In the embodiment of the present application, the first wireless charging coil 102 of the above embodiment can receive a modulated signal including identity information. The first control component 104 in the embodiment of the present application can include a first wireless charging chip 1041 and a first control unit 1042. After receiving the modulated signal, the first wireless charging chip 1041 can demodulate the modulated information and send the demodulated identity information to the first control unit 1042. The first control unit 1042 can modify the configuration information of the wireless network component 105 based on the identity information to achieve interconnection between the scanner host and the scanner base.
[0060] Based on the above solution, the embodiment of the present application can easily realize wireless interconnection between the scanner host and the scanner base, so that the scanner host can be interconnected with multiple scanner bases.
[0061] An embodiment of the present application also provides a scanner, which includes the scanner host of any one of the above-mentioned scanner host embodiments.
[0062] The scanner provided in the embodiment of the present application can achieve the same or at least similar technical effects as the above-mentioned scanner host embodiment, and will not be repeated here.
[0063] Figure 6 A schematic diagram of a scanner base structure provided in an embodiment of the present application. In some embodiments, the scanner further includes a scanner base.
[0064] The scanner base includes a second wireless charging coil 106 , the shape of which matches the shape of the first wireless charging coil 102 .
[0065] like Figure 6As shown, the second wireless charging coil 106 is used to interact with the first wireless charging coil 102 to charge the scanner host. After the first wireless charging coil 102 is configured to match the shape of the inner wall of the accommodating cavity of the scanner host, the second wireless charging coil 106 can match the shape of the first wireless charging coil 102. Specifically, the second wireless charging coil 106 can have the same or similar shape as the first wireless charging coil 102, and the minimum distance between any position of the second wireless charging coil 106 and the first wireless charging coil 102 is equal. Figure 6 As shown, Figure 6 In the embodiment, the second wireless charging coil 106 is exemplarily configured as an arc structure. Thus, the second wireless charging coil 106 can interact with the first wireless charging coil 102, so that the scanner base can charge the scanner host.
[0066] Figure 7 A schematic diagram of another scanner base structure provided in an embodiment of the present application. In some embodiments, the scanner base further includes a second positioning member 107 , which is used to align the second wireless charging coil 106 with the first wireless charging coil 102 .
[0067] The second positioning member 107 can be, for example, a positioning pin, a positioning slot, or the like. Through the above structure, the second wireless charging coil 106 can be aligned with the first wireless charging coil 102 .
[0068] In some embodiments, the second positioning member 107 includes a second permanent magnet.
[0069] The second positioning member 107 may also be a second permanent magnet. The second permanent magnet can attract the scanner host through its magnetic force, so that the first wireless charging coil 102 can be aligned with the second wireless charging coil 106 more easily.
[0070] In some embodiments, the first positioning member 103 and the second positioning member 107 may both be permanent magnets, and the first positioning member 103 and the second positioning member 107 have opposite magnetic poles on their facing sides.
[0071] Figure 8 The circuit structure diagram of a scanner base provided in an embodiment of the present application is shown in FIG. In some embodiments, the scanner base further includes a second control component 108 and a wireless access component 109 .
[0072] The second control component 108 is electrically connected between the second wireless charging coil 106 and the wireless access component 109. The second control component 108 is used to obtain the identity information corresponding to the wireless access component 109, generate a modulation signal, and send the modulation signal to the scanner host through the second wireless charging coil 106.
[0073] The wireless access component 109 is used for wireless interconnection with the scanner host.
[0074] In the embodiment of the present application, a modulated signal including identity information can be transmitted via the second wireless charging coil 106 in the above-described embodiment. The second control component 108 in the embodiment of the present application can include a second wireless charging chip 1081 and a second control unit 1082. The second wireless charging chip 1081 can automatically identify the scanner host after it is placed in the scanner base and transmit the information to the second control unit 1082. The second control unit 1082 can obtain the identity information from the wireless access component 109, modulate the identity information, and generate a modulated signal that is transmitted to the scanner host via the second wireless charging coil 106, thereby completing the wireless connection between the scanner host and the scanner base.
[0075] Based on the above solution, the embodiment of the present application can easily realize wireless interconnection between the scanner host and the scanner base, so that the scanner host can be interconnected with multiple scanner bases.
[0076] Figure 9 A schematic diagram of another scanner host structure provided in an embodiment of the present application. Figure 10 This is another schematic diagram of the scanner base structure provided in the embodiment of the present application. Figure 9 and Figure 10 As can be seen from the structure shown in the figure, the arc-shaped first wireless charging coil 102 and the second wireless charging coil 106 can be aligned with each other, thereby achieving the purpose of charging the scanner host and realizing wireless charging greater than or equal to 5W.
[0077] In some embodiments, the scanner includes at least an oral scanner.
[0078] Specifically, the scanner in the embodiments of the present application may be an oral scanner. Since oral scanners need to be inserted into the patient's oral cavity, miniaturization is a more pressing requirement. Consequently, the space within the scanner housing corresponding to an oral scanner is more limited. The solution provided in the embodiments of the present application avoids excessive unused space, freeing up more space for other components within the housing, thereby facilitating miniaturization of the scanner housing.
[0079] In addition, the scanner provided in the embodiment of the present application can also be a facial scanner, an industrial scanner, a professional scanner, etc., which can realize three-dimensional reconstruction of objects or scenes such as teeth, faces, human bodies, industrial products, industrial equipment, cultural relics, artworks, prostheses, medical devices, and buildings.

Moreover, the term "comprises" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
