[0020] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0022] The 3D scanning device will be described in detail below through specific embodiments: Reference Figures 1 to 9 As shown, some embodiments of this application provide a three-dimensional scanning device, including a scanner host 1 and a handle 2.

[0023] The scanner host 1 includes an imaging section 101 facing the object being scanned during scanning, a back section 102 opposite to the imaging section 101, and a side section 103 located between the imaging section 101 and the back section 102. A first connection area 10 is provided on the side section 103, and the first connection area 10 includes a first electrical contact point 11. The handle 2 is provided with a second connection area 20, which is located at the end of the handle 2. The second connection area 20 includes a second connection part, which is configured as a detachable attachment structure to the first connection part.

[0024] In other words, the scanner main unit 1 and the handle 2 are independent components. When handheld scanning is required, the user can detachably connect the second connecting part of the handle 2 to the first connecting part of the scanner main unit 1. That is, the handle 2 can be attached and fixed to the scanner main unit 1, so that the two are tightly connected together to meet the needs of handheld scanning. When fixed scanning is required, the handle 2 can be detached, and the scanner main unit 1 can be installed separately on a tripod or robotic arm. At this time, the scanner main unit 1 can perform scanning operations independently.

[0025] The 3D scanning device of this application achieves rapid switching between handheld and fixed modes through modular design. This ensures that it can be operated by hand while significantly reducing the size of the scanner host 1 when used independently. It solves the problem of volume redundancy caused by the integrated design of traditional devices and significantly improves the portability and application flexibility of the device.

[0026] It should be noted that the scanner host 1 is the core functional component of the 3D scanning device. It integrates an optical scanning module, image processing unit, control circuitry, and necessary sensors for scanning and processing the obtained information. In some examples, the scanner host 1 also includes a display screen for showing the 3D information of the scanned object.

[0027] In a specific implementation, when the second connecting part is attached to the first connecting part, the handle 2 is perpendicular to the side 103. Specifically, the central axis of the handle 2 is perpendicular to the plane where the side 103 is located, so that the handle 2 and the scanner host 1 after connection present a T-shaped structure as a whole. When handheld, the three-dimensional scanning device of this application has high stability.

[0028] In some embodiments, the first connection area 10 further includes a first connection part, the handle 2 is provided with a first power source, and the second connection area 20 further includes a second electrical connection contact 21 electrically connected to the first power source. The second electrical connection contact 21 contacts the first electrical connection contact 11 to supply power to the scanner host 1 through the first power source.

[0029] The design of the aforementioned electrical contact points ensures that when the handle is attached to the scanner host, the second electrical contact point and the first electrical contact point make physical contact to form a circuit path and achieve electrical connection. At this time, the first power source on the handle can supply power to the scanner host.

[0030] In some embodiments, refer to Figure 2 and Figure 3 As shown, the first connecting portion includes a first magnetic element 121, and the second connecting portion includes a second magnetic element 221. The second magnetic element 221 and the first magnetic element 121 are magnetically attracted to each other. Specifically, In a specific implementation, the first magnetic component 121 can be a plurality of first sub-magnetic components embedded in the bottom of the scanner host 1, for example, intermittently arranged along the circumferential direction. The first electrical contact point 11 is located in the area surrounded by the plurality of first sub-magnetic components. The first sub-magnetic component can be a neodymium iron boron permanent magnet ring or a magnet. The second magnetic component 221 is correspondingly set as a plurality of second sub-magnetic components embedded in the top of the handle 2, for example, intermittently arranged along the circumferential direction. The second electrical contact point is located in the area surrounded by the plurality of second sub-magnetic components. The second sub-magnetic component can be a neodymium iron boron permanent magnet ring or a magnet.

[0031] Multiple second sub-magnetic components are magnetically attached to multiple first sub-magnetic components. When the handle 2 is close to the scanner host 1, the magnetic attraction will cause the two to automatically align and fit tightly. At this time, the first electrical connection contact 11 and the second electrical connection contact 21 are electrically connected to achieve power supply or communication.

[0032] This setup allows for quick operation and docking to complete electrical and mechanical connections. The first magnetic component 121 and the second magnetic component 221 are designed without physical clip wear issues, resulting in a long service life and making them suitable for on-site scanning scenarios that require frequent disassembly and assembly.

[0033] In other embodiments, reference is made to Figure 4 and Figure 5 As shown, the first connecting part includes a wall 131 that surrounds the first connecting area and extends to the side. The wall 131 forms an insertion channel 132. One end of the wall 131 is open to form an insertion inlet 133 of the insertion channel 132, and the other end is closed to form a limiting wall 134. The two opposite side walls of the insertion channel 132 are provided with first guide grooves 135, and the two first guide grooves 135 extend along the first direction A.

[0034] The second connecting part includes a plug-in part 231, a base 232, and a second guide groove 233 located between the plug-in part 231 and the base 232. The plug-in part 231 is inserted into the insertion channel 132 from the plug-in inlet 133 along the first direction A. The two sides of the plug-in part 231 are adapted to the first guide groove 135, and at least part of the wall 131 is adapted to the second guide groove 233. The first electrical contact point 11 is located on the inner side of the top wall of the wall 131, and the second electrical contact point 21 is located on the top surface of the plug-in part 231. That is to say, the plug-in part 231 can be confined within the insertion channel 132 by a simple push-insertion operation. After the plug-in part 231 cooperates with the insertion channel 132, the two sides of the plug-in part 231 cooperate with the first guide groove 135, and the wall 131 cooperates with the second guide groove 233, mechanical fixation and electrical connection can be completed simultaneously. The structure has high stability and strong torsional resistance, making it suitable for use in vibration environments.

[0035] It is understood that the adaptation of two or more parts / components / parts / structures described herein means that the two or more parts / components / parts / structures have shapes and sizes that can cooperate / complement each other (e.g., be designed and manufactured), and the cooperation between the two or more parts / components / parts / structures can be, for example, a cooperation with at least partial friction.

[0036] In a specific implementation, the insertion channel 132 is formed as a T-shaped or other suitable or irregularly shaped slot machined on the bottom of the scanner host 1. The cross-section of the insertion part 231 and the second guide groove 233 is adapted to the insertion channel 132 to limit the second connection part in the insertion channel 132 and prevent accidental drop.

[0037] Continue to refer to Figure 4 and Figure 5 As shown, the insertion part 231 is provided with an elastic latch 234 that can move up and down relative to the top surface of the insertion part 231. The top wall of the insertion channel 132 is provided with a socket 136. The elastic latch 234 is configured such that when the second connecting part is fully abutted against the first connecting part, the elastic latch 234 protrudes from the top surface of the insertion part 231 and inserts into the socket 136, which can be represented as a locked state. When the elastic latch 234 disengages from the socket 136 and is at most flush with the top surface of the insertion part 231, the second connecting part can disengage from the first connecting part, which can be represented as an unlocked state. It can be understood that by setting a mechanical interlocking structure (i.e., the locking engagement between the elastic latch 234 and the socket 136), it can be ensured that the scanner host will not accidentally disengage from the handle when moving or moving, thus significantly improving reliability.

[0038] Furthermore, the elastic buckle 234 includes a buckle body and a handle 235 disposed on the side of the buckle body; a first channel is provided on the top of the insertion part 231, and the buckle body is adapted to the first channel so that the elastic buckle 234 can move up and down relative to the top surface of the insertion part 231, that is, switch between the locked state and the unlocked state; a second channel is provided on the side of the insertion part 231, and the second channel is connected to the first channel; the handle 235 is slidably adapted to the second channel so that the handle 235 can move up and down in the second channel to drive the displacement of the buckle body.

[0039] In practice, an elastic element is provided between the elastic buckle 234 and the bottom wall of the first channel, and the handle 235 can be exposed outside the second connecting part through the second channel so that when the handle 235 is pulled, the elastic buckle 234 can move up and down relative to the top surface of the insertion part 231, that is, switch between the unlocked state and the locked state, so as to facilitate the removal and installation of the handle 2.

[0040] Furthermore, in the direction in which the insertion part 231 is inserted into the channel 132, i.e., in the first direction A, referring to... Figure 4 As shown by the middle arrow, the front side of the elastic buckle 234 is formed as an inclined guide surface. When the elastic buckle 234 abuts against the top wall of the insertion channel 132, it can compress the elastic element and allow the elastic buckle 234 to retract to the top surface of the insertion part 231, ensuring the smooth insertion of the insertion part 231. Thus, the first connecting part and the second connecting part can be directly connected by pushing the handle 2. After pulling the latch 235 to disengage the elastic buckle 234 from the insertion hole 136, the first connecting part and the second connecting part can be separated, making the operation simple.

[0041] In yet other embodiments, reference is made to Figure 6 and Figure 7 As shown, the first connecting part includes an arc-shaped clearance groove 141 and an arc-shaped locking arm 142 disposed on the groove wall of the arc-shaped clearance groove 141. The first electrical contact point 11 is located in the area enclosed by the arc-shaped locking arm 142. The second connecting part includes a knob buckle 24, which is adapted to the arc-shaped clearance groove 141. An arc-shaped channel 241 is formed inside the knob buckle 24. The second electrical contact point 21 is located in the area enclosed by the arc-shaped channel 241. One end of the arc-shaped channel 241 forms a knob inlet, and the other end forms an abutment wall. The arc-shaped locking arm 142 is inserted into the arc-shaped channel 241 from the knob inlet along the circumferential direction of the arc-shaped channel. The abutment wall is used to form an abutment limit with the arc-shaped locking arm 142 when it is inserted.

[0042] In other words, the knob 24 slides into the arc-shaped clearance groove 141, allowing the knob 24 to rotate and be confined within the arc-shaped clearance groove 141. Specifically, the arc-shaped locking arm 142 is located at the end of the arc-shaped clearance groove 141, that is, at the far end in the rotation direction of the knob 24. When the knob 24 rotates to the end, the arc-shaped locking arm 142 can engage with the arc-shaped channel 241 to form a mechanical interlock, thereby achieving the connection between the first connecting part and the second connecting part, while occupying little space.

[0043] Furthermore, referring to Figure 6 As shown, a guide slope 242 is formed on the outer side of the knob 24, that is, the end away from the screwing direction, so that when the knob 24 is screwed out in the opposite direction, the guide knob 24 can be disengaged from the arc-shaped relief groove 141. In this way, the first connecting part and the second connecting part can be directly separated or connected by directly turning the handle 2, which is simple to operate.

[0044] In some other embodiments, reference is made to Figure 8 and Figure 9 As shown, the first connecting part includes a column 151 extending away from the side and a locking block 152 located at the end of the column 151 away from the side. The second connecting part includes a locking groove 251 provided on the handle 2. The locking groove 251 has a locking entrance formed on the surface of the handle 2. Guide blocks 252 are provided at the positions of the opposite side walls of the locking groove 251 near the groove entrance. The locking block 152 passes through the locking entrance, passes the guide block 252 and is inserted into the locking groove 251, and the column 151 is inserted between the two guide blocks 252.

[0045] It is understandable that the handle 2 moves toward or away from the scanner host 1 along its own axis, which can complete the engagement and disengagement of the locking block 152 and the locking groove 251, making operation convenient.

[0046] Meanwhile, when the locking block 152 passes through the locking inlet and is inserted into the locking groove 251, the locking block 152 can be prevented from coming out under the limiting effect of the two guide blocks 252, thus ensuring connection stability.

[0047] In some embodiments, the first electrical contact 11 is a contact base, which is connected to the control circuit board of the scanner host 1 via a wire. The second electrical contact 21 is a contact spring, which is elastically connected to the handle 2. After the handle 2 and the scanner host 1 are connected, the contact spring contacts the contact base and forms an electrical connection. When the scanner host 1 is connected to the handle 2, the contact spring is pressed into the contact base with a certain pressure, ensuring that the contact resistance between the contact spring and the contact base remains within a controllable range under vibration, thereby ensuring stable power supply or communication. Of course, the first electrical contact 11 and the second electrical contact 21 can also have other structural forms, such as the first electrical contact 11 being a contact spring and the second electrical contact 21 being a contact base. This application does not limit this and can be specifically set according to actual needs.

[0048] In some embodiments, the scanner host 1 is provided with a first interface 16, and the handle 2 is provided with a second interface 26. A connecting cable is provided between the second interface 26 and the first interface 16 to achieve communication. The first interface 16 can be a USB interface or a Type-C interface, and the second interface 26 can be a USB interface or a Type-C interface. The first interface 16 and the second interface 26 can be electrically connected via the connecting cable. Wired connection ensures stable communication and power supply, avoiding additional interference. Simultaneously, the physical interface can also serve as an emergency charging interface, improving the flexibility of device use.

[0049] In some embodiments, the scanner host 1 is provided with a first wireless communication module, and the handle 2 is provided with a second wireless communication module. The second wireless communication module and the first wireless communication module are wirelessly connected to each other to eliminate the constraints of physical connection lines, so that the handle 2 can be used remotely and is suitable for diverse application scenarios.

[0050] In some embodiments, the handle 2 is equipped with a processor that can cooperate with the computing module within the scanner host 1 to process information; that is, the processor in the handle 2 can assist the scanner host 1 in data processing. It is understood that a distributed computing architecture can reduce power consumption and heat generation on the scanner host 1, thereby increasing continuous operating time.

[0051] Furthermore, the handle 2 can be adapted to different models of scanner host 1, and can support new scanning algorithms through software upgrades, thus extending the system's technical life cycle.

[0052] In some embodiments, the scanner host 1 is provided with a second power supply, which supplies power to the scanner host 1 when the handle 2 is detached from the scanner host 1, or supplies power to the scanner host 1 in conjunction with the first power supply when the handle 2 is connected to the scanner host 1, or supplies power to the scanner host 1 independently when the handle 2 is connected to the scanner host 1. That is, when power is detected from the handle 2, the scanner host 1 can automatically switch to external power supply mode and charge the built-in second power supply; when the scanner host 1 is detached from the handle 2, its built-in second power supply can support independent operation of the scanner host 1. This ensures that scanning operations are not interrupted in any working mode, providing high applicability. In other examples, the scanner host can also be independently powered by the second power supply in the attached state, without using the first power supply on the handle. Of course, the first power supply and the second power supply can also be coordinated through a power adapter to meet different usage needs.

[0053] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0054] The above are merely specific embodiments of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application.
