[0051] The lens 21 of the camera of the embodiment of the present application can be shielded to be hidden, and can be used in bedrooms of homes or nursing homes to be suitable for scenes that do not require long-term shooting.

[0052] As shown in Figures 1 to 5c, a camera according to an embodiment of the present application includes a housing 1, a lens assembly 2, a mounting bracket 3, a flip cover 4, and a motor 5. The lens assembly 2 includes a lens 21. The housing 1 is provided with a storage chamber 11 and a window 12 communicating with the storage chamber 11. The lens 21, the mounting bracket 3, the flip cover 4, and the motor 5 are located within the storage chamber 11. The flip cover 4 is rotatably mounted to the mounting bracket 3. The flip cover 4 includes a shielding portion 41 and a fixing portion 42 connected to the shielding portion 41. The motor shaft 51 of the motor 5 is directly fixed to the fixing portion 42 to drive the flip cover 4 to switch between an open position and a closed position. In the closed position, the shielding portion 41 blocks the window 12, concealing the lens 21. In the open position, the shielding portion 41 moves away from the window 12 and into the storage chamber 11, revealing the lens 21.

[0053] The camera directly drives the flip cover 4 to rotate through the motor 5 to realize the flipping action of the flip cover 4. The structure is simple and the number of parts in the transmission system is reduced, which not only reduces the cost, but also improves the assembly efficiency and reliability. The flip cover 4 is located in the storage cavity 11. In the open state, the shielding part 41 enters the storage cavity 11, and the camera is neat and tidy.

[0054] The lens assembly 2 and the motor 5 are fixed to the mounting bracket 3 by locking screws, which facilitates assembly and disassembly.

[0055] As shown in Figure 1, the housing 1 includes a front cover 13 and a rear cover 14 fixed together. The front cover 13 and the rear cover 14 enclose the storage cavity 11. The window 12 is provided in the front cover 13. The housing 1 has an inverted triangular shape in the lateral direction. The angle between the plane of the front cover 13 and the plane of the rear cover 14 is an acute angle, optionally 35 degrees.

[0056] The tilted design of the front cover 13 effectively utilizes the wide-angle lens 21's visual range, minimizing both near- and far-end blind spots. For example, with a 2mm focal length lens 21 and a vertical field of view of 152 degrees, and a 35-degree tilt of the front cover 13 at a normal installation height, the near-end blind spot is only 0.3 meters, enabling seamless observation of human subjects.

[0057] As shown in FIG1 , in the open state, the lens 21 can be tilted downward and extended forward to achieve monitoring without blind spots. Extending the lens 21 outward avoids structural interference with the field of view, which may cause black edges to appear on the image.

[0058] As shown in Figure 2, the flip cover 4 has a consistent appearance gap with the front cover 13 in the closed position, which has a better appearance effect. Referring to Figures 5a to 9, the mounting frame 3 includes a bottom wall 31 and a first side wall 32 and a second side wall 33 extending from the bottom wall 31. The lens 21 is located between the first side wall 32 and the second side wall 33. The second side wall 33 is provided with a first hole 331 for the fixing portion 42 or the motor shaft 51 to pass through. As shown in Figures 5a, 5b and 5c, one end of the flip cover 4 is mounted on the first side wall 32 to support one end of the flip cover 4, and the other end of the flip cover 4 is connected to the output shaft of the motor 5 through the first hole 331 of the second side wall 33, and the second side wall 33 is used to support the other end of the flip cover 4.

[0059] The flip cover 4 also includes a mounting portion 43. One of the first side wall 32 and the mounting portion 43 is provided with a shaft portion 321, and the other is provided with a mounting hole 431. The shaft portion 321 is rotatably assembled into the mounting hole 431 to enhance the stability and smooth rotation of the flip cover 4. In the embodiment shown in Figures 5a and 5c, the mounting portion 43 is provided with a mounting hole 431, and one end of the first side wall 32 is provided with the shaft portion 321. By fitting the mounting hole 431 of the mounting portion 43 over the shaft portion 321, one end of the flip cover 4 is connected to the mounting bracket 3.

[0060] As shown in Figure 7, the mounting bracket 3 is fixed to the front cover 13. The mounting bracket 3 includes a pair of abutting portions 34 extending from the bottom wall 31. The pair of abutting portions 34 abut against the housing 1 to increase the stability of the mounting bracket 3. The bottom wall 31 and the pair of abutting portions 34 form a channel 341. When the flip cover 4 rotates, the shielding portion 41 enters the channel 341 to shield the lens 21. The mounting bracket 3 and the front cover 13 can be fixed by fasteners. As shown in Figure 7, the mounting bracket 3 is provided with three first assembly holes 35. Referring to Figure 4b, the front cover 13 is provided with three second assembly holes 131 corresponding to the first assembly holes 35. The fasteners pass through the three first assembly holes 35 and the three second assembly holes 131 to fix the mounting bracket 3 to the front cover 13.

[0061] The motor 5 and the mounting bracket 3 can also be fixed by fasteners. As shown in Figure 5a, the motor 5 includes two hanging ears 52. As shown in Figure 7, the second side wall 33 of the mounting bracket 3 also includes two third assembly holes 36. The fasteners pass through the hanging ears 52 and the third assembly holes 36 to fix the motor 5 on the mounting bracket 3.

[0062] As shown in Figures 7 to 12, the flip cover 4 includes a first ear portion 44 and a second ear portion 45 connected to the shielding portion 41. The fixing portion 42 is provided on the first ear portion 44, and the mounting portion 43 is provided on the second ear portion 45. A boss 441 is provided on the first ear portion 44. The second sidewall 33 is provided with a first stop portion 332 and a second stop portion 333. In the closed position, one end of the boss 441 abuts against the first stop portion 332, while in the open position, the opposite end of the boss 441 abuts against the second stop portion 333, thereby limiting the rotation angle of the flip cover 4 and preventing it from colliding with the lens 21 during movement. Optionally, when the motor 5 rotates 75 degrees, the opposite end of the boss 441 abuts against the second stop portion 333, and the flip cover 4 is in the open position.

[0063] The shielding portion 41 is plate-shaped, and the first ear portion 44 and the second ear portion 45 extend from one side of the shielding portion 41 to the top thereof.

[0064] 11 , the first ear portion 44 defines a second hole 440, into which the end of the motor shaft 51 is received. The cross-section of the end of the motor shaft 51 and the second hole 440 are shaped to prevent the motor shaft 51 from rotating relative to the flip cover 4.

[0065] The first retaining portion 332 forms a first groove 3321, and the second retaining portion 333 forms a second groove 3331. In the closed position, one end of the protrusion 441 is received in the first groove 3321, and in the open position, the opposite end of the protrusion 441 is received in the second groove 3331, thereby ensuring the stability of the flip cover 4 after it stops.

[0066] The shape of one end of the protrusion 441 matches the shape of the first groove 3321, and the shape of the opposite end of the protrusion 441 matches the shape of the second groove 3331. When one end of the protrusion 441 is received in the first groove 3321 and the opposite end of the protrusion 441 is received in the second groove 3331, further rotation of the flip cover 4 is prevented. Referring to Figures 8, 9, and 10, the shape of the first arc segment 441a of the protrusion 441 matches the shape of the first groove 3321, and the shape of the second arc segment 441b of the protrusion 441 matches the shape of the second groove 3331.

[0067] The camera includes a damping member 6 , which is sleeved onto the shaft portion 321 . The damping member 6 is located between the first side wall 32 and the mounting portion 43 .

[0068] The damping member 6 can be made of silica gel or rubber.

[0069] 4a to 6 , 9 and 13 to 15 , the mounting hole 431 is provided on the mounting portion 43 , and the shaft portion 321 is provided on the first side wall 32 and has a positioning hole 3211 . The mounting portion 43 is located outside the first side wall 32 .

[0070] The camera includes a locking member 7. The locking member 7 includes a head 71 and a positioning portion 72 extending from the head 71. The positioning portion 72 is assembled from the outside of the shaft portion 321 into the positioning hole 3211 and fixed to the shaft portion 321. The head 71 is located outside the mounting portion 43 and is in contact with the mounting portion 43.

[0071] When the locking member 7 is locked on the shaft 321, the head 71 of the locking member 7 presses the flip cover 4, thereby causing the flip cover 4 to press the damping member 6, avoiding the damping force difference caused by inconsistent torque when the locking member 7 is locked, and ensuring that the damping force of the camera is stable and consistent.

[0072] The locking member 7 may be a screw, and the positioning portion 72 is screwed and fixed to the shaft portion 321 .

[0073] The first sidewall 32 defines a recess 322 and a ridge 323 within the recess 322. The damping member 6 is received within the recess 322 and defines a notch 61. The ridge 323 is received within the notch 61, preventing the damping member 6 from rotating freely due to friction, effectively limiting the position of the damping member 6 and providing stable damping.

[0074] One or more notches 61 and edges 323 may be provided.

[0075] The motor 5 of the present application is a conventional stepping motor, and its motor shaft 51 has a return clearance of about 3 degrees. Within this range, the motor 5 cannot provide a self-locking force for the flip cover 4. In order to solve the shaking of the flip cover 4 caused by the inherent return clearance of the motor 5, the damping member 6 is provided to provide a certain damping for the flip cover 4.

[0076] To calibrate the number of revolutions of the motor 5, as shown in FIG5d , the camera further includes a photoelectric sensor 22 and a photoelectric baffle 442. The photoelectric sensor 22 includes a sensing portion 221 and a circuit board 222. The sensing portion 221 is fixed to one end of the circuit board 222, and the sensing portion 221 is in an inverted U-shape. The other end of the circuit board 222 is fixed to the second side wall 33 of the mounting bracket 3 via a screw 223. The photoelectric baffle 442 is disposed on the first ear 44 of the flip cover 4. The first ear 44 can rotate relative to the second side wall 33 under the drive of the motor 5, thereby driving the photoelectric baffle 442 to engage or disengage with the sensing portion 221. When the photoelectric baffle 442 engages with the sensing portion 221, the current position of the motor 5 can be fed back to the control device. The control device then calibrates the number of revolutions of the motor 5 based on the current position, thereby preventing the motor from over- or under-rotating. The motor 5 may also be of other types, and this application does not limit the type of the motor 5.

[0077] The damping member 6 provides stable resistance in the vertical axis. When one end of the boss 441 abuts against the first stop portion 332, the motor 5 stops rotating. The resistance of the damping member 6 acts on the flip cover 4 to prevent the flip cover 4 from shaking freely within the return clearance of the motor 5, thereby ensuring that the flip cover 4 has the same appearance gap as the front cover 13 in the closed position, and there is no step difference with the flip cover 4, which has a better appearance effect.

[0078] The camera includes a detection device and a control device. The control device controls the operation of the motor 5 according to the detection result of the detection device to drive the flip cover 4 to rotate.

[0079] Under normal working conditions, the flip cover 4 is in the closed position and the lens 21 is blocked by the flip cover 4. At this time, the detection device and the control device are working; when external conditions trigger the need to open the lens 21 for shooting, the motor 5 rotates to drive the flip cover 4 to the open position, and the lens 21 shoots normally, and the external information is confirmed through the actual image; after the shooting is completed, the motor 5 rotates to drive the flip cover 4 to the closed position.

[0080] After the shooting is completed, the motor 5 can be started by a preset time or detection method to drive the flip cover 4 to the closed position.

[0081] For example, when an abnormal situation occurs in the bedroom, the camera is activated to remotely monitor the situation in the bedroom. For example, when there is a bedridden patient and no one moves around in the bedroom for a long time, the camera automatically starts to monitor whether there is any abnormality.

[0082] The detection device can perform detection by radar or infrared, etc. Referring to FIG4 a and FIG16 , the detection device includes a radar assembly 81 , and the radar assembly 81 is provided with a fixing hole 811 .

[0083] The housing 1 is provided with a positioning post 15. The positioning post 15 is disposed on the front cover 13. The positioning post 15 is assembled into the fixing hole 811. The camera includes a fixing screw 82 and a buffer pad 83. The fixing screw 82 is fixed to the positioning post 15. The buffer pad 83 is sleeved onto the positioning post 15 and is located between the fixing screw 82 and the radar assembly 81.

[0084] To ensure the precise fixing of radar assembly 81, it is directly fixed to the front cover 13 to avoid the cumulative error caused by other adapters. Because the clearance between radar assembly 81 and front cover 13 is small, for example, 1.5mm, to ensure the engagement depth of fixing screw 82, positioning column 15 is passed through radar assembly 81 and fixed with fixing screw 82.

[0085] As shown in Figures 17 to 26, the camera includes a fixing bracket 9. The fixing bracket 9 can be fixed to the wall using expansion screws. The fixing bracket 9 can also be fixed to the wall in other ways, and this application does not limit the fixing method of the fixing bracket 9 to the wall.

[0086] The rear cover 14 is fixed to the fixing bracket 9 to secure the camera. Optionally, the rear cover 14 can be detachably assembled to the fixing bracket 9. This allows the camera to be mounted to the fixing bracket 9 after first securing the fixing bracket 9 to the wall, making installation and removal of the camera more convenient.

[0087] Referring to Figures 25 and 26, the fixing bracket 9 includes a first mounting surface 91 and a pair of second mounting surfaces 92 located at opposite ends of the first mounting surface 91. The second mounting surfaces 92 are arranged at an angle relative to the first mounting surface 91, and the plane on which the second mounting surfaces 92 lie is perpendicular. When the camera is wall-mounted, it abuts against the first mounting surface 91. When the camera is corner-mounted, it abuts against the second mounting surfaces 92. This allows a single fixing bracket 9 to be compatible with both wall and corner mounting, ensuring ease of use and adapting to a variety of installation scenarios, thereby saving costs.

[0088] Referring to Figure 20a, the fixing bracket 9 includes a first latch 95 disposed on the side wall 93. Referring to Figures 18 and 20b, the rear cover 14 includes a second latch 141. The camera is mounted to the fixing bracket 9 from top to bottom, so that the first latch 95 and the second latch 141 are locked and secured, facilitating assembly and disassembly of the camera. The camera and fixing bracket 9 can also be locked with screws.

[0089] The number of the first buckle 95 and the second buckle 141 can be one or more. A plurality of the first buckles 95 and the second buckle 141 can increase the stability of the camera.

[0090] The first buckle 95 and / or the second buckle 141 are provided with a protrusion 951, and the design of local small surface interference prevents the camera from shaking after installation.

[0091] Referring to Figures 17 and 18 , the fixing bracket 9 includes sidewalls 93 and a pair of flanges 94 extending from opposite ends of the sidewalls 93. When the camera is secured to the fixing bracket 9, the rear side of the rear cover 14 is positioned within the space enclosed by the sidewalls 93 and the flanges 94. When the camera is positioned near the fixing bracket 9, the flanges 94 cooperate with the rear cover 14 to limit the camera's position in the left-right direction and assist in guiding the second latch 141 to more accurately engage the first latch 95, improving installation efficiency.

[0092] 20a, 20b, 21, 22, 23, and 24, the fixing bracket 9 includes an elastic arm 96 disposed on the side wall 93. When the first latch 95 and the second latch 141 are engaged, the elastic arm 96 snaps into the groove 142 of the rear cover 14 to abut against the rear cover 14, thereby preventing the camera from moving upward and thus preventing the camera from detaching from the fixing bracket 9. When installing the camera, the sound and vibration generated by the change from the compressed to the released state of the elastic arm 96 when the elastic arm 96 snaps into the groove 142 can provide the user with obvious feedback that the camera is in place, thereby reminding the user that the camera is installed in place, which is more user-friendly and can also ensure the stability of the camera after installation.

[0093] 1 to 9 , a camera for a nursing home according to an embodiment of the present application includes:
