Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a novel light reflection device. Background Technology

[0002] With the increasingly sophisticated development of supporting software for smart terminals such as mobile phones and tablets, these terminals are gradually becoming application equipment in the industrial technology field. For example, in the field of 3D scanning technology, mobile phones or tablets equipped with structured light or Time-of-Flight (TOF) cameras can capture 3D information. 3D imaging scanning accurately records the 3D information of the user, especially the 3D contour information of the face, in digital form. By installing a 3D scanning application on the mobile phone or tablet and launching the program, the user can acquire and analyze 3D data information through the smart terminal. However, the structured light or TOF cameras on existing mobile phones or tablets are generally mounted on the front screen. Therefore, when using the 3D imaging scanning function, the user needs to point the structured light or TOF camera at the object being scanned, making it impossible to operate the front screen during the operation, which greatly increases the difficulty of operation.

[0003] To address this issue, we have developed a light reflection device, as described in the Chinese Utility Model Patent Publication No. CN215526101U. This device includes a mounting frame, a support frame, and a reflector. The mounting frame is used to mount the reflector, and the mounting frame and support frame are connected. A first angle is formed between the first side of the mounting frame and the first side of the support frame. The reflector is mounted on the first side of the mounting frame, and the angle between the reflective surface of the reflector and the first side of the support frame is acute. A light guide hole is provided on the first side of the support frame, and a fixing part is provided to fix the support frame. By mounting the fixing part of this reflection device on a smart terminal equipped with a structured light camera and / or a TOF camera, it is no longer necessary to align the structured light camera and / or TOF camera with the object to be measured; only the reflector needs to be aligned with the object. This not only facilitates 3D scanning but also simplifies equipment operation. However, during use and research, we found that the mounting bracket of the light reflection device is fixed at an angle to the plane where the structured light camera or TOF camera is located. For application scenarios that require adjustment of the scanning angle, it may be impossible to operate the front screen normally. Utility Model Content

[0004] The main purpose of this utility model is to propose a new type of light reflection device and three-dimensional scanning equipment, which aims to solve the technical problem that the angle between the mounting bracket of the existing light reflection device and the plane where the structured light camera or TOF camera is located is fixed, and the front screen may not be able to be operated normally in application scenarios where the scanning angle needs to be adjusted.

[0005] To achieve the above objectives, this utility model proposes a novel light reflection device, comprising a mounting frame, a support frame, and a reflector. The mounting frame is hinged to the support frame, and the reflector is fixedly connected to the mounting frame. The support frame includes a hinge seat and a clamping part, and the hinge seat is hinged to the mounting frame.

[0006] Optionally, the clamping part includes an abutment plate and a clamping plate, the abutment plate and the clamping plate are disposed on the same side of the hinge seat, and the abutment plate, the clamping plate and the hinge seat form a C-shaped clamping structure.

[0007] Optionally, the clamping plate is made of engineering plastic.

[0008] Optionally, the free end of the clamping plate is provided with an arc-shaped guide inner wall that approaches the abutment plate.

[0009] Optionally, the clamping plate and the hinged seat are connected by a curved arm structure.

[0010] Optionally, the abutment plate and clamping plate of the hinge seat are provided with screw holes on opposite sides. The mounting bracket includes a rearview mirror mounting frame and a hinge arm. One end of the hinge arm is fixedly connected to one side of the rearview mirror mounting frame. The other end of the hinge arm is provided with a hinge through hole and is rotatably fixedly connected to the screw hole by a screw passing through the hinge through hole. The screw nut is provided with a cap.

[0011] Optionally, an arc-shaped stop is provided on the outer side of the screw hole of the hinge seat, and an arc-shaped groove is provided on the outer side of the hinge through hole end of the hinge arm. When the hinge arm and the hinge seat are rotatably and fixedly connected, the arc-shaped stop is embedded in the arc-shaped groove and rotates within the arc-shaped groove.

[0012] Optionally, the angle of the arc-shaped groove is 40 degrees.

[0013] Optionally, a toggle part is provided on one side of the hinge arm of the reflector mounting frame.

[0014] The beneficial effects of this utility model are:

[0015] This invention proposes a novel light reflection device that can be directly applied to smart devices such as mobile phones or tablets equipped with structured light cameras and / or TOF cameras. Due to the hinged connection between the mounting bracket and the support frame, the angle between the reflector and the structured light camera and / or TOF camera can be adjusted as needed. After the user launches the 3D scanning application installed on the smart device, the application acquires the light reflected from the reflector through the structured light camera and / or TOF camera, thereby completing the data acquisition of the object to be scanned. The hinged connection between the mounting bracket and the support frame allows for scanning in different scenarios by directly adjusting the angle between the support frame and the mounting bracket, without needing to adjust the angle of the structured light camera and / or TOF camera. This eliminates the need to rotate the smart device, allowing users to operate the front screen more conveniently and normally. Attached Figure Description

[0026] Please refer to Figures 1 to 4This utility model proposes a novel light reflection device (hereinafter referred to as the reflection device), including a mounting frame 01, a support frame 03 and a reflector 05. The mounting frame 01 is hinged to the support frame 03, and the reflector 05 is fixedly connected to the mounting frame 01. The support frame 03 includes a hinge seat 031 and a clamping part 032, and the hinge seat 031 is hinged to the mounting frame 01. The reflector can be rectangular or other shapes, preferably elongated rectangular. The corresponding mounting bracket 01 may include an elongated rectangular reflector mounting frame 011, in which the reflector 05 is fixedly mounted. The mounting bracket 01 also includes a hinge arm 012, located on one side of the reflector mounting frame. The free end of the hinge arm 012 has a hinge through hole 013 along the length of the reflector mounting frame. The clamping part 032 of the support frame includes an abutment plate 033 and a clamping plate 034. The abutment plate has a smooth plate-like structure, and the clamping plate has an arc-shaped guide inner wall 035 at its free end that approaches the abutment plate. This arc-shaped guide inner wall of the abutment plate not only makes the insertion of smart devices such as mobile phones and tablets into the support frame smoother but also increases the clamping plate's strength. Clamping force; wherein, the abutment plate 033 and the clamping plate 034 are disposed on the same side of the hinge seat 031 and on the same side as the reflector mounting frame 011. The abutment plate, the clamping plate and the hinge seat form a C-shaped clamping structure. In use, the intelligent equipment is inserted from the open end of the C-shaped clamping structure, ensuring that the mirror side of the reflector faces the structure light camera and / or TOF camera of the intelligent equipment. The other side of the hinge seat 031 (the side opposite to the abutment plate and the clamping plate) is provided with a screw hole 038. The screw 06 is screwed into the screw hole 038 through the hinge through hole 013, so that the mounting bracket is hinged to the hinge seat with the screw as the hinge axis. In use, the angle between the reflector and the structure light camera and / or TOF camera is adjusted, and the screw is further tightened to fix the hinge arm, so as to achieve a rotatable fixed connection.

[0027] This reflective device can be directly applied to smart devices such as mobile phones or tablets equipped with structured light cameras and / or TOF cameras. Due to the hinged connection between the mounting bracket and the support frame, the angle between the reflector and the structured light camera and / or TOF camera can be adjusted as needed. After the user launches the 3D scanning application installed on the smart device, the application acquires the light reflected from the reflector through the structured light camera and / or TOF camera, thereby completing the data acquisition of the object to be scanned. The hinged connection between the mounting bracket and the support frame allows for scanning in different scenarios by directly adjusting the angle between the support frame and the mounting bracket, without needing to adjust the angle of the structured light camera and / or TOF camera. This eliminates the need to rotate the smart device, allowing users to operate the front screen more conveniently and normally.

[0028] In one embodiment, the clamping plate 034 is made of engineering plastic. Engineering plastic has excellent comprehensive properties, high rigidity, low creep, high mechanical strength, and good heat resistance. During its use, the deformation of the clamping plate and the recovery force after deformation can compress the intelligent equipment and the abutment plate to clamp the intelligent equipment together.

[0029] In one embodiment, a curved arm structure 036 is provided at the end of the clamping plate 034 that connects to the hinge seat 031. The curved arm structure can increase the deformation range of the clamping plate, thereby increasing the clamping force of the clamping plate and the maximum width between the clamping plate and the abutment plate, thus enabling this reflective device to be used with smart equipment of different thicknesses.

[0030] In one embodiment, a cap 062 is provided at the nut 061 of the screw 06. The cap allows the screw to be rotated more easily, thereby fixing the hinge arm and realizing a rotatable and fixed connection between the mounting bracket and the support bracket.

[0031] In one embodiment, an arc-shaped stop 037 is provided on the outer side of the screw hole 038 of the hinge base 031, and an arc-shaped groove 014 is provided on the outer side of the hinge through hole 013 of the hinge arm 012. When the hinge arm 012 and the hinge base 031 are rotatably and fixedly connected, the arc-shaped stop 037 is embedded in the arc-shaped groove 014 and rotates within the arc-shaped groove 014. The cooperation between the arc-shaped groove and the arc-shaped stop can limit the rotation angle of the hinge arm, thereby limiting the angle adjustment range of the reflector and the structured light camera and / or TOF camera.

[0032] Specifically, in one embodiment, the angle of the arc-shaped groove 014 is 40 degrees.

[0033] In another embodiment, a toggle part 015 is provided on one side of the hinge arm 012 of the reflector mounting frame 011. By toggling the reflector mounting part with the toggle part, the user is prevented from touching the reflector during use, thus preventing contamination of the reflector.

[0034] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
