[0034] The face recognition camera assembly of the embodiment of the utility model cooperates with the positioning assembly 22 of the support seat 2 through the adjustment disk 12 of the camera module 1, and the positioning assembly 22 is rotatably abutted along the circumference of the adjustment disk 12, and the positioning assembly 22 is rotatable relative to the positioning portion. In this way, the rotation of the camera module 1 and the movement along the circumference of the adjustment disk 12 can be realized. Then, the movement of the camera module 1 in the up and down and front and back directions is realized. Thereby, the moving range of the camera module 1 is improved, and the camera module 1 can be adjusted to the ideal position according to the actual situation of the person during face recognition, so that the spinal surgery can obtain a better field of view and enhance the accuracy of face recognition.

[0035] The face recognition camera assembly of the embodiment of the utility model has the advantages of high convenience of use and high recognition accuracy.

[0036] The thickness direction of the adjustment disk 12 is consistent with the width direction of the camera assembly, and the positioning assembly 22 extends along the width direction of the camera assembly. For example, there can be two adjustment disks 12, namely, a first adjustment disk and a second adjustment disk, and the first adjustment disk and the second adjustment disk are respectively arranged on the module body 11 on both sides of the width direction of the camera assembly for face recognition. There are two positioning assemblies 22, namely, a first positioning assembly and a second positioning assembly, and the first positioning assembly and the second positioning assembly are arranged on the seat body 21 at intervals along the width direction of the camera assembly for face recognition. The first positioning assembly is movably abutted against the first adjustment disk, and the second positioning assembly is movably abutted against the second adjustment disk, so as to switch between multiple positioning parts to realize the rotation of the camera module 1 and the displacement of the preset direction.

[0037] like Figure 5 As shown, the positioning portion is a positioning tooth groove 121 provided on the adjusting disk 12 , and the positioning component 22 has a limiting tooth, which is engaged in the positioning tooth groove 121 .

[0038] The face recognition camera assembly of the embodiment of the utility model has the advantage of simple structure by setting the positioning part as the positioning tooth groove 121 and the limiting tooth is engaged in the positioning tooth groove 121.

[0039] Furthermore, the positioning tooth groove 121 is a shallow groove.

[0040] Optionally, the adjusting disk 12 is substantially circular, and the positioning tooth grooves 121 extend along the radial direction of the adjusting disk 12. A plurality of positioning tooth grooves 121 are arranged at intervals along the circumference of the adjusting disk 12.

[0041] The embodiments of the present invention are not limited thereto. For example, in other embodiments, Figure 4 As shown, the positioning portion is a positioning hole 122 provided on the adjusting disk 12 , and the positioning assembly 22 includes a positioning rod 223 , and the positioning rod 223 can be switchably abutted in different positioning holes 122 .

[0042] The face recognition camera assembly of the embodiment of the utility model sets the positioning part as the positioning hole 122, and the positioning rod 223 can be switchably abutted in different positioning holes 122 to realize the positioning of the camera module 1. Therefore, the camera assembly has the advantages of simple structure and high processing convenience.

[0043] Furthermore, the side wall of the positioning hole 122 along the depth direction thereof is tilted to form a slope surface, thereby reducing the difficulty of adjusting the camera module 1 .

[0044] like Figure 4 As shown, a side of the adjustment disk 12 close to the positioning assembly 22 has a guide groove 123 to guide the positioning rod 223 to switch between different positioning holes 122 .

[0045] The face recognition camera assembly of the embodiment of the utility model can limit the adjustment stroke of the positioning assembly 22 relative to the adjustment disk 12 through the guide groove 123, preventing the camera module 1 from moving beyond the stroke range. Thus, the difficulty of adjusting the position and angle of the camera module 1 is further reduced.

[0046] like Figure 1 and Figure 2 As shown, the base body 21 includes a base plate and multiple side plates 213 , two of the multiple side plates 213 are erected on the base plate at intervals along the width direction of the face recognition camera assembly, and the positioning assembly 22 is penetrated on the side plates 213 .

[0047] The face recognition camera assembly of the embodiment of the utility model divides the base 21 into a base plate and a plurality of side plates 213, and the side plates 213 provide a rotation space and corresponding support for the installation of the camera module 1. Therefore, the camera assembly has the advantages of simple structure and easy installation.

[0048] Furthermore, the side plate 213 can be welded to the upper surface of the base body 21 .

[0050] The face recognition camera assembly of the embodiment of the utility model divides the positioning assembly 22 into a compression spring 221, a pull rod 222 and a positioning rod 223, and the two ends of the compression spring 221 are abutted against the pull rod 222 and the positioning rod 223, so that when installing the camera module 1, only one side of the positioning assembly 22 needs to be squeezed to provide corresponding space for the camera module 1. Therefore, the camera assembly has the advantage of high installation convenience.

[0051] Further, the side plate 213 can be a cavity structure formed by splicing an inner plate and an outer plate, the compression spring 221 is located in the cavity of the side plate 213, the section of the pull rod 222 having the limiting protrusion is passed through the outer plate and is located in the cavity, and the section of the pull rod 222 having the limiting protrusion also has an extension section, and the compression spring 221 is sleeved on the extension section. The one end of the positioning rod 223 has an abutment protrusion, and the one end of the positioning rod 223 having the abutment protrusion is passed through the inner plate and is located in the cavity. The two ends of the compression spring 221 are respectively abutted between the abutment protrusion and the limiting protrusion.

[0052] Furthermore, the tie rod 222 is threadedly connected to the side plate 213. It is understandable that the tie rod 222 can be moved along the width direction of the camera assembly, and then after the camera module 1 is installed in place, the tie rod 222 can be further adjusted to increase the abutment force of the positioning rod 223 on the positioning portion. In addition, by adjusting the tie rod 222 along the width direction of the camera assembly, camera modules 1 of different models and sizes can also be used. Therefore, the camera assembly improves the applicability of the support base 2.

[0053] The positioning part is a positioning hole 122 provided on the adjusting disk 12, and the other end of the positioning rod 223 is spherical, so that the camera module 1 can be universally rotated relative to the support seat 2, thereby further improving the flexibility of the camera module 1.

[0054] The base plate includes a plate body 211 and a mounting member 212. The mounting member 212 is disposed on the plate body 211 and can be threadedly connected to the mounting seat. Thus, the camera assembly has the advantage of high installation convenience.

[0055] like Figures 1 to 3 As shown, the mounting member 212 includes a bolt 2121, a hollow cylinder 2122, and a rotating rod 2123.

[0056] The face recognition camera assembly of the embodiment of the utility model has the advantage that the head of the bolt 2121 is prevented from being exposed to the outside and affecting the aesthetics by providing the hollow tube 2122 structure.

[0057] The present invention is not limited thereto, for example, in other embodiments, the plate 211 has a stepped hole, the mounting member 212 is a bolt 2121, and the head of the bolt 2121 abuts against the stepped hole. Similarly, the head of the bolt 2121 can be prevented from being exposed outside and affecting the aesthetics.

[0058] The module body 11 has one of a slot and a block, the adjustment disk 12 has the other of a slot and a block, and the block is engaged in the slot. In other words, the module body 11 has a slot, and the adjustment disk 12 has a block. Or the module body 11 has a block, and the adjustment disk 12 has a slot. Thus, the convenience of assembling the camera module 1 is improved.
