It is not very effective in scanning the inner surfaces of products, and is not convenient to use. It cannot effectively scan the inner surfaces of products, resulting in the scanned 3D images of products not being detailed enough.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the existing three-dimensional scanning devices have the defects of poor convenience and low efficiency in scanning the inner surface of products. Utility Model Content

The input end is provided with a light inlet hole, and scanning light is irradiated into the searchlight head through the light inlet hole. The plane of the output end is relatively inclined to the plane of the input end. The output end is provided with a reflector for reflecting the scanning light. A light outlet hole is also provided on one side of the output end. The light outlet hole is arranged opposite to the reflector at an interval, and the light outlet hole passes through the side wall of the searchlight head.

[0007] Through the setting of the searchlight, the searchlight is extended into the interior of the product to be scanned during scanning, and the scanning light enters the searchlight from the light inlet hole. The scanning light is irradiated on the reflector, and is emitted from the light outlet hole after being reflected by the reflector. After being emitted from the light outlet hole, the scanning light scans the interior of the product to be scanned.

[0008] Preferably, the searchlight head further includes:

[0009] A sinking groove is sunken below the plane of the output end, and the reflector is arranged in the sinking groove.

[0010] By adopting the above technical solution and setting the sinking groove, when the reflector is assembled on the output end of the search head, the outer surface of the reflector and the plane of the output end remain in the same plane, thereby reducing scratches caused by collision between the reflector and the inside of the product to be scanned, and improving the safety of the inner cavity three-dimensional scanning device when in use.

[0011] Preferably, an anti-collision plane is further provided on the output end of the searchlight head, and the anti-collision plane is provided between the output end and a side wall close to the light exit hole.

[0013] Preferably, the input end of the searchlight head is also sleeved with a connecting ring, and the connecting ring is used to connect the searchlight head to the rotating motor through screws.

[0014] By adopting the above technical solution and setting the connecting ring, it is convenient to stably assemble the searchlight head on the output end of the rotating motor, and convenient to drive the searchlight head to rotate inside the product to be scanned by the rotating motor, so that the scanning light can perform rotational scanning inside the product to be scanned.

[0015] Preferably, the output end of the rotating motor is connected to the connecting ring, and the rotating axis of the rotating motor is coaxial with the axis of the searchlight.

[0016] By adopting the above technical solution, the coaxial arrangement of the rotating motor and the searchlight head facilitates the scanning light to enter the searchlight head, while reducing the collision volume when the searchlight head rotates.

[0017] Preferably, the rotating motor is provided with a light-passing hole which penetrates the rotating motor along the axial direction, and the light-passing hole is used for allowing the scanning light to pass through.

[0018] By adopting the above technical solution and setting the light-passing hole, it is convenient for the scanning light to pass through the rotating motor and enter the search head.

[0019] Preferably, a light emitting device is provided on a side of the rotating motor away from the searchlight, and an output end of the light emitting device is provided corresponding to the light hole for emitting the scanning light.

[0020] By adopting the above technical solution, the light emitting device is configured to emit the scanning light, and the inside of the product to be scanned is scanned by the scanning light.

[0021] Preferably, the reflector is a single-sided reflector, and the reflector is close to the inner side of the search head and is used to reflect the scanning light.

[0022] By adopting the above technical solution, the reflector is a single-sided mirror, and the reflector close to the inner side of the searchlight is used to reflect the scanning light, thereby reducing the influence of the reflector away from the inner side of the searchlight on the internal light of the product to be scanned.
