The camera is usually driven by a pan / tilt head to rotate. This is a technical inspiration for the camera; Research on the camera revealed the following issues: The camera needs to be driven by a motor to rotate and shoot. Since the camera is usually installed outdoors in a complex outdoor environment, the camera surface is easily hit by falling debris. After the camera is hit by debris, the camera cannot form protection on the top surface to avoid damage to the surface due to the impact of debris. At the same time, the camera is easily affected by the impact. The motor and rotating mechanism at the end, resulting in the camera being unable to form rotation protection; At present, CN201611088616.4 in the prior art discloses a rotatable camera mechanism with a protective shell, and discloses a camera mechanism.

A driving servo motor is fixed on the upper outer wall of the driving box body, and the camera can be automatically rotated and extended out or entered into the protective box body, so that dust will not accumulate when not in use, thereby protecting the camera and ensuring its service life, and the camera is easy to install and disassemble; The present invention can mainly solve the problem that the camera cannot form rotation protection. Summary of the invention

[0003] The purpose of the present invention is to provide a camera rotation protection device and a protection method thereof.

[0004] To achieve the above object, the present invention provides the following technical solutions: A camera rotation protection device and a protection method thereof include a camera and a pan head, wherein the pan head is located at one end of the camera, the back side of the camera is rotatably connected to a chuck, an end of the pan head close to the camera is rotatably connected to a rotating ring and a rotating table, an end of the rotating table away from the pan head is provided with a support frame, an end of the support frame is provided with a motor, and an output end of the motor is rotatably connected to the chuck.

[0005] As a further solution of the present invention: the pan head is installed on the wall by bolts, a micro motor is arranged inside the pan head, the micro motor, the camera and the motor are connected to the power circuit through a power cord, and the micro motor drives the rotating table to rotate through a rotating ring.

[0006] As a further solution of the present invention: the interior of the chuck is hollow, and a track is provided at one end of the chuck close to the camera, and the track is in a circular ring shape.

[0007] As a further solution of the present invention: a groove is formed at one end of the support frame away from the rotating table, the end of the chuck is rotatably engaged with the inner side of the groove, and the output end of the motor passes through the interior of the groove.

[0008] As a further solution of the present invention: a track is opened at the end of the pan-tilt head, the width of the rotating ring is 1-2 cm smaller than the width of the internal track of the pan-tilt head, the turntable rotates at the end of the pan-tilt head through the rotating ring, and the inner side of the rotating ring is penetrated by grooves.

[0009] As a further solution of the present invention: a protrusion is provided at one end of the camera close to the chuck, and a clamping frame is provided at one end of the protrusion away from the camera.

[0010] As a further solution of the present invention: one end of the clamping frame is rotatably clamped to the upper and lower ends inside the chuck track, the clamping frame is located at both ends of the protrusion, and the clamping frame is arranged in an arc shape with an arc angle of 90-120°.

[0011] As a further solution of the present invention: the lower part of the chuck is swingably connected to a bottom ring, the upper part of the chuck is swingably connected to a top ring, and a connecting ring is provided between the bottom ring and the top ring.

[0012] As a further solution of the present invention: the bottom ring and the top ring are both connected to the clamping frame, the weight of the bottom ring is 200-300g greater than the weight of the top ring, and the bottom ring, the connecting ring and the top ring are combined into a circular ring shape.

[0013] As a further solution of the present invention: a rotary bearing is swingably connected inside the groove of the rotating ring, a liner is swingably connected to one side of the rotary bearing, and a cushion block is arranged at the lower end of the inside of the liner.

[0014] As a further solution of the present invention: the rotary bearing is arranged in a transverse manner, the rotary bearing is arranged around the inner side of the rotating ring, and the liner and the cushion block are arranged in conjunction with the rotary bearing.

[0015] As a further solution of the present invention: the weight of the lining is 1-2g. When the rotating bearing is not swinging, the bottom of the lining and the end of the pad are in contact with the inner wall of the gimbal track. The interior of the lining is hollow, and the end of the pad close to the inner wall of the gimbal track is a frosted surface.

[0016] As a further solution of the present invention: the protection method comprises the following steps: S1: The gimbal is installed on the wall with bolts. The gimbal is installed vertically as a whole. The micro motor, camera and motor are all connected to the remote controller signal. The micro motor inside the gimbal drives the rotating ring to rotate. The micro motor drives the rotating table to rotate through the rotating ring. Therefore, the rotating table drives the camera to rotate horizontally through the support frame for shooting. S2: The remote controller controls the motor to run, and the motor drives the chuck to swing in a vertical direction, so that the motor can drive the camera to rotate in both directions through the chuck to shoot; S3: The camera is rotatably connected to the chuck through the protrusion and the clamping frame. When the motor drives the chuck to rotate in the vertical direction, one end of the clamping frame is rotatably connected to the upper and lower ends of the chuck track, so that the chuck can drive the camera to rotate in the vertical direction synchronously through the clamping frame and the protrusion to shoot; S4: When the upper end of the camera is hit, the camera drives the card holder to swing tiltedly through the protrusion, and the card holder swings inside the track of the card. Since the bottom ring and the top ring are connected to the card holder, when the camera swings tiltedly due to the top impact, the card holder swings tilted synchronously; S5: The clamping frame drives the bottom ring and the top ring to rotate synchronously. The weight of the bottom ring is 200-300g greater than that of the top ring. After the camera rotates 90°, the debris on the top of the camera falls off. By utilizing the weight difference between the bottom ring and the top ring, the bottom ring can rotate upward 90° and then rotate downward as a whole. The bottom ring drives the top ring to return to its original position through the connecting ring. S6: When the micro motor inside the gimbal drives the rotating ring to rotate, the rotating ring generates inertia. Since there is a track at the end of the gimbal, the width of the rotating ring is 1-2 cm smaller than the width of the track inside the gimbal. At this time, the lining plate inside the groove of the rotating ring swings upward through the rotating bearing, and a gap is generated between the bottom of the lining plate and the inner wall of the gimbal track. S7: After the rotating ring stops rotating, the liner swings downward through the rotating bearing, and the bottom of the liner and the end of the pad fit with the inner wall of the gimbal track. At this time, the liner and the pad can increase the friction between the rotating ring and the inner wall of the gimbal track. Beneficial Effects

[0017] 1. The camera is rotatably connected to the chuck through the protrusion and the card holder. When the motor drives the chuck to rotate in the vertical direction, one end of the card holder is rotatably connected to the upper and lower ends of the chuck track, so that the chuck can drive the camera to rotate in the vertical direction synchronously through the card holder and the protrusion to shoot. When the upper end of the camera is hit, the camera drives the card holder to swing obliquely through the protrusion, and the card holder swings inside the track of the card; 2. Since the bottom ring and the top ring are both connected to the clamping frame, when the camera is tilted and swung due to the impact from the top, the clamping frame will also tilt and swung synchronously. By utilizing the rotatability of the camera, it is possible to prevent debris from falling to the upper end of the camera and causing damage to the upper end of the camera, thereby achieving a protective effect; 3. The clamping frame drives the bottom ring and the top ring to rotate synchronously. The weight of the bottom ring is 200-300g greater than that of the top ring. After the camera rotates 90°, debris on the top of the camera falls off. By utilizing the weight difference between the bottom ring and the top ring, the bottom ring can rotate upward 90° and then rotate downward as a whole. The bottom ring drives the top ring to return through the connecting ring, so that the bottom ring and the top ring drive the camera to return through the clamping frame respectively. This allows the camera to form rotation protection after debris falls on the top, avoiding damage to the chuck and motor at the end of the camera due to the weight of the debris, thereby protecting the rotation mechanism of the camera. 4. When the micro motor inside the gimbal drives the rotating ring to rotate, the rotating ring generates inertia. Since there is a track at the end of the gimbal, the width of the rotating ring is 1-2cm smaller than the width of the track inside the gimbal. At this time, the lining plate inside the groove of the rotating ring swings upward through the rotating bearing, and the bottom of the lining plate is spaced from the inner wall of the gimbal track. Therefore, the lining plate cannot affect the normal rotation of the rotating ring. 5. After the rotating ring stops rotating, the liner swings downward through the rotating bearing, and the bottom of the liner and the end of the pad fit with the inner wall of the gimbal track. At this time, the liner and the pad can increase the friction between the rotating ring and the inner wall of the gimbal track, preventing the rotating ring from continuing to rotate due to inertia after the micro motor inside the gimbal stops rotating; 6. The motor drives the chuck and the camera to rotate. When the top of the camera is hit by debris, the camera can rotate, and after the rotation, the debris is driven to fall downward to prevent the top of the camera from being damaged after the impact. At the same time, the camera can be reset after rotation to prevent the chuck and the motor from being affected by the impact. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 3 As shown; The support frame 103 has a groove at one end of the support frame 103 away from the rotating table 102, and the end of the chuck 105 is rotatably engaged with the inner side of the groove, and the output end of the motor 104 passes through the inner side of the groove; The end of the chuck 105 is rotatably engaged with the inner side of the groove, and the output end of the motor 104 passes through the inner side of the groove, so that the motor 104 drives the camera 1 to rotate and shoot through the chuck 105; The rotating ring 4 is provided with a track at the end of the pan / tilt head 101. The width of the rotating ring 4 is 1-2 cm smaller than the width of the track inside the pan / tilt head 101. The turntable 102 rotates at the end of the pan / tilt head 101 through the rotating ring 4. The inner side of the rotating ring 4 is penetrated by grooves. Wherein: the pan head 101 is installed on the wall by bolts, the pan head 101 is installed in a vertical direction as a whole, the micro motor, the camera 1 and the motor 104 are all connected to the remote controller signal, the micro motor inside the pan head 101 drives the rotating ring 4 to rotate, and the micro motor drives the rotating table 102 to rotate through the rotating ring 4, so that the rotating table 102 drives the camera 1 to rotate horizontally for shooting through the support frame 103, and the remote controller controls the motor 104 to run, and the motor 104 drives the chuck 105 to swing in a vertical direction, so that the motor 104 can drive the camera 1 to rotate in both directions for shooting through the chuck 105; Example 2: Refer to the attached manual Figure 1-5 As can be seen from 10, the difference between Example 2 and Example 1 is that a protrusion 2 is provided at one end of the camera 1 close to the chuck 105, and a clamping frame 201 is provided at one end of the protrusion 2 away from the camera 1; Among them: the protrusion 2 and the clamping frame 201, one end of the clamping frame 201 is rotated and clamped to the upper and lower ends of the inner track of the chuck 105, the clamping frame 201 is located at both ends of the protrusion 2, and the clamping frame 201 is set in an arc shape with an arc angle of 90-120°; Wherein: the camera 1 is rotatably connected with the chuck 105 through the protrusion 2 and the clamping frame 201. When the motor 104 drives the chuck 105 to rotate in the vertical direction, one end of the clamping frame 201 is rotatably connected to the upper and lower ends of the track inside the chuck 105, so that the chuck 105 can drive the camera 1 to rotate in the vertical direction synchronously through the clamping frame 201 and the protrusion 2 to shoot. When the upper end of the camera 1 is hit, the camera 1 drives the clamping frame 201 to swing obliquely through the protrusion 2, and the clamping frame 201 swings inside the track of the card 105; Example 3: Refer to the attached manual Figure 1-6 It can be seen that the difference between Example 3 and Example 1-2 is that the lower part of the chuck 105 is swingably connected to the bottom ring 3, the upper part of the chuck 105 is swingably connected to the top ring 302, and a connecting ring 301 is provided between the bottom ring 3 and the top ring 302; Wherein: the bottom ring 3 and the top ring 302, the bottom ring 3 and the top ring 302 are both connected to the clamping frame 201, the weight of the bottom ring 3 is 200-300g greater than the weight of the top ring 302, and the bottom ring 3, the connecting ring 301 and the top ring 302 are combined into a circular ring shape; Among them: since the bottom ring 3 and the top ring 302 are both connected to the clamping frame 201, when the camera 1 is tilted and swung due to the top impact, the clamping frame 201 is tilted and swung synchronously, and the rotatability of the camera 1 can prevent debris from falling to the upper end of the camera 1 and causing damage to the upper end of the camera 1, thereby achieving a protective effect; The clamping frame 201 drives the bottom ring 3 and the top ring 302 to rotate synchronously. The weight of the bottom ring 3 is 200-300g greater than that of the top ring 302. After the camera 1 rotates 90°, debris on the upper end of the camera 1 falls off. By utilizing the weight difference between the bottom ring 3 and the top ring 302, the bottom ring 3 can rotate upward 90° and then rotate downward as a whole to return to its original position. The bottom ring 3 drives the top ring 302 to return to its original position through the connecting ring 301, so that the bottom ring 3 and the top ring 302 drive the camera 1 to return to its original position respectively through the clamping frame 201, so that the camera 1 can form a rotation protection after the top debris falls off, avoiding the situation that the chuck 105 and the motor 104 at the end of the camera 1 are damaged due to the weight of the debris, and thus the rotation mechanism of the camera 1 can be protected; Example 4: Refer to the attached manual Figure 2 , 7 -9 It can be seen that the difference between Example 4 and Example 1-3 is that a rotating bearing 401 is swingably connected inside the groove of the rotating ring 4, a lining plate 402 is swingably connected to one side of the rotating bearing 401, and a cushion block 403 is arranged at the lower end of the lining plate 402; Wherein: the rotating bearing 401 is arranged in a transverse direction, the rotating bearing 401 is arranged around the inner side of the rotating ring 4, and the lining plate 402 and the cushion block 403 are matched with the rotating bearing 401; The inner side of the rotating ring 4 is penetrated by grooves, and there are 6-8 grooves; The lining plate 402 and the cushion block 403, the lining plate 402 weighs 1-2g, when the rotary bearing 401 is not swinging, the bottom of the lining plate 402 and the end of the cushion block 403 are in contact with the inner wall of the track of the gimbal 101, the interior of the lining plate 402 is hollow, and the end of the cushion block 403 close to the inner wall of the track of the gimbal 101 is a frosted surface; One end of the pad 403 close to the inner wall of the track of the pan / tilt head 101 is a frosted surface, which can increase the friction between the lining plate 402 and the inner wall of the track of the pan / tilt head 101; When the micro motor inside the pan / tilt 101 drives the rotating ring 4 to rotate, the rotating ring 4 generates inertia. Since a track is provided at the end of the pan / tilt 101, the width of the rotating ring 4 is 1-2 cm smaller than the width of the track inside the pan / tilt 101. At this time, the lining plate 402 inside the groove of the rotating ring 4 swings upward through the rotating bearing 401. The bottom of the lining plate 402 is spaced from the inner wall of the track of the pan / tilt 101. Therefore, the lining plate 402 cannot affect the normal rotation of the rotating ring 4. After the rotating ring 4 stops rotating, the lining plate 402 swings downward through the rotating bearing 401, and the bottom of the lining plate 402 and the end of the cushion block 403 fit the inner wall of the track of the gimbal 101. At this time, the lining plate 402 and the cushion block 403 can increase the friction between the rotating ring 4 and the inner wall of the track of the gimbal 101, thereby preventing the rotating ring 4 from continuing to rotate as a whole due to inertia after the micro motor inside the gimbal 101 stops rotating. Example

[0030] The protection method includes the following steps: S1: The pan / tilt head 101 is mounted on the wall by bolts. The pan / tilt head 101 is installed in a vertical direction as a whole. The micro motor, the camera 1 and the motor 104 are all connected to the remote controller signal. The micro motor inside the pan / tilt head 101 drives the rotating ring 4 to rotate. The micro motor drives the rotating table 102 to rotate through the rotating ring 4. Therefore, the rotating table 102 drives the camera 1 to rotate horizontally through the support frame 103 to shoot; S2: The remote controller controls the motor 104 to run, and the motor 104 drives the chuck 105 to swing in a vertical direction, so that the motor 104 can drive the camera 1 to rotate in both directions through the chuck 105 to shoot; S3: The camera 1 is rotatably connected with the chuck 105 through the protrusion 2 and the clamping frame 201. When the motor 104 drives the chuck 105 to rotate in the vertical direction, one end of the clamping frame 201 is rotatably connected to the upper and lower ends of the track of the chuck 105, so that the chuck 105 can drive the camera 1 to rotate in the vertical direction synchronously through the clamping frame 201 and the protrusion 2 to shoot; S4: When the upper end of the camera 1 is hit, the camera 1 drives the clamping frame 201 to swing obliquely through the protrusion 2, and the clamping frame 201 swings inside the track of the card 105. Since the bottom ring 3 and the top ring 302 are both connected to the clamping frame 201, when the camera 1 swings obliquely due to the top impact, the clamping frame 201 swings obliquely synchronously; S5: The clamping frame 201 drives the bottom ring 3 and the top ring 302 to rotate synchronously. The weight of the bottom ring 3 is 200-300g greater than that of the top ring 302. After the camera 1 rotates 90°, the debris on the upper end of the camera 1 falls off. By utilizing the weight difference between the bottom ring 3 and the top ring 302, the bottom ring 3 can rotate upward 90° and then rotate downward as a whole to return to its original position. The bottom ring 3 drives the top ring 302 to return to its original position through the connecting ring 301. S6: When the micro motor inside the gimbal 101 drives the rotating ring 4 to rotate, the rotating ring 4 generates inertia. Since a track is provided at the end of the gimbal 101, the width of the rotating ring 4 is 1-2 cm smaller than the width of the track inside the gimbal 101. At this time, the lining plate 402 inside the groove of the rotating ring 4 swings upward through the rotating bearing 401, and a gap is generated between the bottom of the lining plate 402 and the inner wall of the track of the gimbal 101. S7: After the rotating ring 4 stops rotating, the lining plate 402 swings downward through the rotating bearing 401, and the bottom of the lining plate 402 and the end of the cushion block 403 fit the inner wall of the track of the gimbal 101. At this time, the lining plate 402 and the cushion block 403 can increase the friction between the rotating ring 4 and the inner wall of the track of the gimbal 101. Through the above steps, the motor 104 drives the chuck 105 and the camera 1 to rotate. When the top of the camera 1 is hit by debris, the camera 1 can rotate, and after the rotation, the debris is driven to fall downward to avoid damage to the top of the camera 1 after the impact. At the same time, the camera 1 can be reset after rotation to avoid the situation where the camera 1 is affected by the impact and affects the chuck 105 and the motor 104.

[0031] The above are only preferred embodiments of the present invention. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the protection scope of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.

The interior of the lining plate (402) is hollow, and one end of the cushion block (403) close to the inner wall of the track of the pan / tilt head (101) is a frosted surface.

10. A method for protecting a camera rotation protection device, characterized in that According to the camera rotation protection device described in claims 1-9, the protection method comprises the following steps: S1: The pan / tilt head (101) is mounted on a wall surface by bolts. The pan / tilt head (101) is mounted vertically as a whole. The micro motor, the camera (1) and the motor (104) are all connected to a remote controller signal. The micro motor inside the pan / tilt head (101) drives the rotating ring (4) to rotate. The micro motor drives the rotating platform (102) to rotate through the rotating ring (4). Therefore, the rotating platform (102) drives the camera (1) to rotate in a horizontal direction through the support frame (103) to shoot. S2: The remote controller controls the motor (104) to operate, and the motor (104) drives the chuck (105) to swing in a vertical direction, so that the motor (104) can drive the camera (1) to rotate in both directions through the chuck (105) to take pictures; S3: The camera (1) is rotatably connected to the chuck (105) via the protrusion (2) and the clamping frame (201). When the motor (104) drives the chuck (105) to rotate in a vertical direction, one end of the clamping frame (201) is rotatably connected to the upper and lower ends of the track of the chuck (105), so that the chuck (105) can drive the camera (1) to rotate in a vertical direction synchronously through the clamping frame (201) and the protrusion (2) to shoot; S4: When the upper end of the camera (1) is impacted, the camera (1) drives the card-connecting frame (201) to swing in an inclined manner through the protrusion (2), and the card-connecting frame (201) swings inside the track of the card (105). Since the bottom ring (3) and the top ring (302) are both connected to the card-connecting frame (201), when the camera (1) swings in an inclined manner due to the impact on the top, the card-connecting frame (201) also swings in an inclined manner synchronously; S5: The clamping frame (201) drives the bottom ring (3) and the top ring (302) to rotate synchronously. The weight of the bottom ring (3) is 200-300 g greater than the weight of the top ring (302). After the camera (1) rotates 90°, debris on the top of the camera (1) falls off. By utilizing the weight difference between the bottom ring (3) and the top ring (302), the bottom ring (3) can rotate upwards 90° and then rotate downwards as a whole to return to its original position. The bottom ring (3) drives the top ring (302) to return to its original position via the connecting ring (301). S6: When the micro motor inside the gimbal (101) drives the rotating ring (4) to rotate, the rotating ring (4) generates inertia. Since a track is provided at the end of the gimbal (101), the width of the rotating ring (4) is 1-2 cm smaller than the width of the track inside the gimbal (101). At this time, the lining plate (402) inside the groove of the rotating ring (4) swings upward through the rotating bearing (401), and a gap is generated between the bottom of the lining plate (402) and the inner wall of the track of the gimbal (101); S7: After the rotating ring (4) stops rotating, the lining plate (402) swings downward through the rotating bearing (401), and the bottom of the lining plate (402) and the end of the cushion block (403) fit with the inner wall of the track of the pan / tilt head (101). At this time, the lining plate (402) and the cushion block (403) can increase the friction between the rotating ring (4) and the inner wall of the track of the pan / tilt head (101).
