Description

Technical Field

[0001] The present invention relates to the technical field of face recognition cameras, and in particular to a lifting face recognition camera module. Background Art

[0002] A face recognition camera is a camera that can identify a person based on their facial features. It uses a camera as an identification information acquisition device to capture a person's facial information in a non-contact manner, and then enters or compares the information through a background computer.

[0003] In existing face recognition cameras, since the protective mirror is exposed to the external environment when in use, dust in the environment is easy to adhere to the mirror.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Example 1

[0047] A push buckle 201 matching and snapping with the buckle male head 103 is provided at the bottom of the motion bracket 2, a hook frame 2061 fitted with the bottom end of the tension spring 1051 is provided on the lower guide seat 206, a magnetic Hall element 1011 is provided on the driving plate 101, and a magnet 202 matching the magnetic Hall element 1011 is provided on the motion bracket 2. The buckle male head 103 and the push buckle 201 can be snap-fitted, and the internal structure of the push buckle 201 can be moved by pressing the lens assembly 3 downward, thereby releasing the position lock of the buckle male head 103 on the push buckle 201, and the elastic deformation recovery of the tension spring 1051 allows the motion bracket 2 to perform a lifting movement inside the outer shell 1. Thereby, the lens assembly 3 is pushed out to the outside of the top surface of the outer shell 1, and then the head front shell 301 can be rotated to adjust the orientation angle of the lens 304 by adjusting the height of the user. After use, the angle of the head front shell 301 is restored to the initial position, and then the lens assembly 3 is pressed downward until the pressing buckle 201 can complete the engagement with the buckle male head 103, so that the buckle male head 103 can lock the position of the pressing buckle 201. The movement of the moving bracket 2 will drive the magnet 202 to move synchronously, so that the magnetic Hall elements 1011 at different installation heights on the driving plate 101 generate induced magnetic changes, which are used to sense the position of the lens assembly 3.

[0048] Specifically, a mounting seat 203 is provided on the top of the motion bracket 2, a lens assembly 3 is provided on the mounting seat 203, the lens assembly 3 includes a hinge group 306 connected to the mounting seat 203, a head front shell 301 is provided on the hinge group 306, a lens 304 is provided at the front of the head front shell 301, a baffle 3061 is provided on the hinge group 306, a lens module 302 and a microphone 307 are provided in the head front shell 301, and a rear cover 303 is also provided at the rear of the head front shell 301. After the head front shell 301 is pushed upward on the mounting seat 203, the head front shell 301 can be rotated toward the lens 304 along the connection axis between it and the hinge group 306, so that the lens 304 can be adjusted at an angle of 0 to 60 degrees, which is convenient for users of different heights. The installation cooperation between the head front shell 301 and the back cover 303 can provide protection for the lens module 302 installed inside the head front shell 301, and the setting of the microphone 307 can perform dual-channel sound pickup processing.

[0049] Specifically, the lens module 302 is provided with a face recognition lens 3021, a main camera 3022 and an infrared fill light 3023. The lens module 302 is also provided with an intermediate link line 305. The hinge group 306 is provided with a protective foam 3051 for protecting the intermediate link line 305. The face recognition lens 3021 is capable of performing face information recognition operations, the main camera 3022 can perform photo and video operations, the infrared fill light 3023 is capable of providing fill light operations when the external environment lighting conditions are insufficient, and the protective foam 3051 is capable of providing protection for the intermediate link line 305 to avoid damage caused by friction between the intermediate link line 305 and the hinge group 306 and the baffle 3061.

[0050] Specifically, the motion bracket 2 is provided with an external tooth groove 204, the damping cup 102 is provided with a spur gear 1021 meshing and matching with the external tooth groove 204, and the driving plate 101 is provided with a connector 1012 connected with the intermediate link line 305. Through the cooperation between the external tooth groove 204 and the spur gear 1021, the speed of the motion bracket 2 in the process of rising and falling inside the outer shell 1 is relatively slow, thereby avoiding a hard collision between the motion bracket 2 and the outer shell 1 due to the setting of the tension spring 1051, and avoiding damage to the internal components of the lens assembly 3 caused by rapid movement. The connector 1012 can be connected to an external control device, so that the external device can complete the control operation of the face recognition lens 3021, the main camera 3022 and the infrared fill light 3023 through the connector 1012 and the intermediate link line 305.

[0051] Specifically, an external top shell 106 is provided on the top of the outer shell 1, and a dust collecting barrel 4 is provided on the external top shell 106. A rotating shaft 401 is provided inside the dust collecting barrel 4, and a brush 4011 acting on the surface of the lens 304 is provided on the rotating shaft 401. The opening end of the dust collecting barrel 4 needs to be close to one side of the lens 304, so as to drive the bristles 4011 to act on the surface of the lens 304 through the rotation of the rotating shaft 401, so as to clean the dust attached to the surface of the lens 304.

[0052] Specifically, a transmission box 5 is provided at the end of the dust collecting barrel 4, a bevel gear A4012 located in the transmission box 5 is provided at the end of the rotating shaft 401, a transmission shaft 501 is provided in the transmission box 5, and a transmission gear A5011 meshing and matching with the bevel gear A4012 is provided at the end of the transmission shaft 501. The rotation of the transmission gear A5011 can drive the bevel gear A4012 to rotate, so that the rotating shaft 401 drives the bristles 4011 to rotate, so that the bristles 4011 act on the surface of the lens 304 to clean the dust on the surface of the lens 304.

[0053] Specifically, a driving shaft 502 is provided at the bottom of the transmission box 5, a bevel gear B5021 is provided on the driving shaft 502, and a transmission gear B5012 meshing and matching with the bevel gear B5021 is provided at the end of the transmission shaft 501. The bevel gear B5021 drives the transmission gear B5012 to rotate, so that the transmission shaft 501 can drive the transmission gear A5011 to rotate.

[0054] Specifically, a driving gear 51 located outside the transmission box 5 is provided at the end of the driving shaft 502, and a rack 7 meshing with the driving gear 51 is provided on the side of the moving bracket 2. During the process of height adjustment of the moving bracket 2 inside the outer shell 1, the rack 7 can mesh with the driving gear 51, so that the driving gear 51 can rotate when the rack 7 moves, thereby driving the driving shaft 502 to rotate. When the moving bracket 2 is adjusted in height inside the outer shell 1, the rotating shaft 401 can drive the bristles 4011 to rotate inside the dust collecting barrel 4 to complete the cleaning operation of the dust on the surface of the lens 304.

[0055] Example 2

[0056] Reference Figure 1-13 The difference between this embodiment and embodiment 1 is that a negative pressure dust box 43 is connected to the bottom of the dust collecting barrel 4, a dusting frame 41 and a hair cleaning frame 42 are arranged in the dust collecting barrel 4, and a hair guiding groove 421 is opened on the hair cleaning frame 42. The dusting frame 41 can make the dust on the surface of the bristles 4011 fall off when the bristles 4011 collide with it, and the negative pressure dust box 43 is used to allow the dust to enter the interior of the negative pressure dust box 43, and then when the bristles 4011 pass through the hair cleaning frame 42, the collision between the hair guiding groove 421 and the bristles 4011 can shake off the dust with strong adhesion on the surface of the bristles 4011, and also allow the dust to enter the interior of the negative pressure dust box 43.

[0057] Specifically, the bottom of the negative pressure dust collecting box 43 is connected to a dust pipe 431, the bottom end of the dust pipe 431 is connected to a venturi tube 6, the output end of the venturi tube 6 is connected to an external exhaust pipe 63, the middle of the venturi tube 6 is provided with a negative pressure pipe 61 connected to the dust pipe 431, and the input end of the venturi tube 6 is provided with an air collecting pipe 62. Through the arrangement of the venturi tube 6, the negative pressure pipe 61 and the dust pipe 431 are used to allow the negative pressure dust collecting box 43 to be connected to the middle section of the venturi tube 6, and the airflow passes through the inside of the venturi tube 6. The situation causes negative pressure to exist in the middle section of the Venturi tube 6, so that the space inside the dust pipe 431 and the negative pressure pipe 61 is in a negative pressure state, so that the negative pressure dust collecting box 43 can also be in a negative pressure state, so that the dust shaken off from the surface of the bristles 4011 can enter the interior of the negative pressure dust collecting box 43, and then through the connection between the negative pressure pipe 61 and the dust pipe 431, the dust can enter the interior of the Venturi tube 6, and through the circulation of the airflow inside the Venturi tube 6, the airflow carrying dust is discharged from the external exhaust pipe 63.

[0058] Specifically, a heat sink 8 for dissipating heat for the lens assembly 3 is provided at the bottom of the dust collecting tube 4, and an exhaust fan blade 801 is provided inside the heat sink 8. An exhaust bin 81 connected to the air collecting pipe 62 is provided at the end of the heat sink 8. Through the setting of the heat sink 8, when the exhaust fan blade 801 is turned on, the heat emitted by the internal components of the lens assembly 3 can be attached to the air, and the air can enter the heat sink 8 through the rotation of the exhaust fan blade 801, and then enter the interior of the venturi 6 through the exhaust bin 81 and the air collecting pipe 62. The circulation of airflow in the venturi 6 makes the inside of the negative pressure pipe 61 and the dust passing pipe 431 in a negative pressure state.

[0059] For other structures not described, refer to Example 1.

[0060] Working principle: In the present invention, before use, the lens assembly 3 is inside the outer shell 1. When in use, the lens assembly 3 needs to be pressed downward to release the lock between the buckle male head 103 and the pressing buckle 201. Then, by utilizing the recovery of the elastic deformation of the tension spring 1051 and the damping effect of the meshing between the outer tooth groove 204 and the spur gear 1021, the height of the motion bracket 2 inside the outer shell 1 can be gradually increased, so as to lift the lens assembly 3 to the upper part of the top surface of the external top shell 106.

[0061] Then, according to the height of the user, the head front shell 301 is rotated so that the angle of the head front shell 301 can be adjusted under the action of the hinge group 306;

[0062] By using the induction magnetic effect between the magnet 202 and the magnetic Hall element 1011, the intermediate link line 305 and the connector 1012 control the opening and closing of the face recognition lens 3021, the main camera 3022 and the infrared fill light 3023;

[0063] After use, the head front shell 301 is restored to the initial position. The initial position requires that the lens 304 is parallel to the outer shell 1, so that the head front shell 301 can be pressed into the inner part of the outer shell 1.

[0064] When the head front shell 301 is pressed down, the tension spring 1051 will produce elastic deformation until the buckle male head 103 can be engaged with the pressing buckle 201, so that the buckle male head 103 can lock the position of the pressing buckle 201, so that the motion bracket 2 can maintain a highly stable position inside the outer shell 1;

[0065] When the moving bracket 2 is adjusted in height inside the outer shell 1, the rack 7 can be meshed with the driving gear 51, so that the driving gear 51 drives the driving shaft 502 to rotate, so that the bevel gear B5021 drives the transmission gear B5012 to rotate, so that the transmission gear A5011 can drive the bevel gear A4012 to rotate, so that the rotating shaft 401 can drive the bristles 4011 to rotate, so that the bristles 4011 act on the surface of the lens 304, and the lens 304 can also be adjusted in height synchronously while cleaning;

[0066] When the lens assembly 3 is in use, the rotation of the exhaust fan blade 801 is turned on to dissipate heat from the internal components of the lens assembly 3 through airflow. The airflow is collected by the heat sink 8, and the concentrated airflow enters the interior of the venturi 6 through the air collecting pipe 62, and then is discharged through the external exhaust pipe 63.

[0067] When air flows through the inside of the Venturi tube 6, a certain negative pressure effect will exist in the internal space of the negative pressure tube 61 and the dust passing tube 431. By utilizing the negative pressure state of the space, the dust shaken off from the surface of the bristles 4011 processed by the dusting rack 41 and the hair cleaning rack 42 will enter the inside of the negative pressure dust collecting box 43. Through the connection between the negative pressure tube 61 and the dust passing tube 431, the air flow circulating inside the Venturi tube 6 will discharge the dust through the external exhaust pipe 63.
