Description

Technical Field

[0001] The utility model relates to the technical field of image processing equipment, in particular to an anti-shake law enforcement recorder. Background Art

[0002] The law enforcement recorder, also known as the law enforcement recording terminal, is a police device that integrates video, photo, intercom, and data transmission functions. It can digitally record dynamic and static on-site situations during public security law enforcement, making it easier for public security officers to use it in law enforcement in various environments. During case handling, the regulatory authorities can use the law enforcement recorder to collect evidence, restore the scene of law enforcement, and avoid disputes. During on-site law enforcement, law enforcement officers need to frequently change positions or even run violently, causing the picture to shake and affecting the shooting effect.

[0003] The utility model with announcement number CN211378096U discloses an anti-shake and anti-vibration law enforcement recorder, including a protective shell, a support frame is fixedly connected to the inside of the protective shell, the four corners of the inner cavity of the support frame are fixedly connected to the rubber seats, a core seat is fixedly connected between the four rubber seats, a core plate is fixedly connected to the inside of the core seat, a rubber plate is clamped and fixed to the front end of the core seat, a protective cover is fixedly connected to the front end of the protective shell, a monitoring device is fixedly connected to the inside of the protective cover, a spring is fixedly connected between the left end face of the core seat and the left wall of the inner cavity of the support frame, a spring is fixedly connected between the right end face of the core seat and the right wall of the inner cavity of the support frame, and a baffle is fixedly connected to the front ends of the four rubber seats. The anti-shake and anti-vibration law enforcement recorder described in the utility model can play a role of buffering, anti-shake and anti-vibration by arranging a spring between the support frame and the core seat, and fixing the core seat to the support frame through the rubber seat, thereby improving the anti-shake and anti-vibration ability of the core plate.

[0004] Because the spring itself has a buffering effect under the action of external force and can be used for shock resistance and vibration reduction, it also has a rebound effect, so the effect of improving the shaking of shooting is general.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Reference Figure 1-7 The utility model is an anti-shake law enforcement recorder, including a shell 1 and a camera 2. The camera 2 is movably installed at the front end of the shell 1 through an anti-shake compensation mechanism 6. The anti-shake compensation mechanism 6 includes a lateral displacement unit 7. A longitudinal displacement unit 8 is installed on the working end of the lateral displacement unit 7. The camera 2 is installed on the working end of the longitudinal displacement unit 8.

[0028] The shell 1 is mainly used to protect the camera 2 and other internal structures. The camera 2 can be a camera with an automatic zoom function. Since the main reason for the image jitter is the relative displacement between the object and the camera during the exposure time, the target light source leaves a shadow on the CCD or CMOS, which will cause the image to be doubled or blurred. Therefore, the image jitter is mainly caused by rapid movement in a short period of time. For example, movement at the moment of camera shooting will cause double or blurred images, while slow movement of the camera during recording will not cause obvious double or blurred images. Therefore, the jitter of the recorder mainly occurs at the moment when the foot lands during walking and running, and the slow movement (relative to the vibration caused by the moment of landing) during the process of lifting and landing will have a much smaller impact on the image jitter. Therefore, for the law enforcement personnel in the process of movement, the main jitter is the left and right directions and the up and down directions. The lateral displacement unit 7 is used to make position compensation for the camera 2 in the left and right directions opposite to the law enforcement personnel's movements, and the longitudinal displacement unit 8 is used to make position compensation in the up and down directions, thereby alleviating the camera 2 shooting jitter.

[0029] Compared with traditional camera gimbals, during the use of law enforcement recorders, the amplitude of the forward and backward extension and the front-to-backward shaking amplitude is less than that in the left-right and up-down directions. Therefore, the anti-shake compensation mechanism 6 reduces the position compensation structure in the front-to-back direction, while reducing the complexity of the structure. By using a camera 2 with an autofocus function, when the picture in the front-to-back direction changes, the picture is mainly adjusted by the autofocus function of the camera 2 to reduce picture blur, which is more suitable for the anti-shake needs of the camera that mainly shakes in the planar direction.

[0030] Since the size of the camera itself is limited, the horizontal moving unit 7 and the vertical moving unit 8 in the present application mainly use millimeter-level and decimeter-level distances as the moving lengths during operation.

[0031] The lateral displacement unit 7 includes a first guide rod 9 and a first screw rod 12 arranged in a horizontal direction, a first nut seat 20 is arranged on the first screw rod 12, a first guide seat 22 is arranged on the first screw rod 12, the first guide seat 22 is the working end of the lateral displacement unit 7, a connecting rod 21 is arranged between the first nut seat 20 and the first guide seat 22, a longitudinal displacement unit 8 is arranged in front of the lateral displacement unit 7, and the longitudinal displacement unit 8 is fixedly connected to the first guide seat 22.

[0032] When the first screw rod 12 rotates, it drives the first nut seat 20 and the first guide seat 22 to move in the horizontal direction, thereby adjusting the positions of the longitudinal displacement unit 8 and the camera 2 in the horizontal direction.

[0033] The longitudinal displacement unit 8 includes a second positioning plate 16 fixedly connected to the first guide seat 22, a second guide rod 13 is arranged between the two second positioning plates 16 in the vertical direction, a second screw 14 is arranged between the two second guide rods 13, the second screw 14 is mounted on the second positioning plate 16 along the vertical rotation, a second nut seat 24 is threadedly connected to the second screw 14, a second guide seat 25 is slidably connected to the first screw 12, the second nut seat 24 and the second guide seat 25 are the working ends of the longitudinal displacement unit 8, and a base 18 is arranged at the rear end of the camera 2, and the base 18 is fixedly connected to the second nut seat 24 and the second guide seat 25.

[0034] When the second screw rod 14 rotates, the second guide seat 25 is driven to move in the vertical direction along the second guide rod 13 through the second nut seat 24, so as to adjust the positions of the base 18 and the camera 2 in the vertical direction.

[0035] In the present application, the two first guide seats 22 and the first nut seat 20, and the two second guide seats 25 and the second nut seat 24 are all connected by connecting rods 21, and a cross layout is formed between the first nut seat 20, the first guide seat 22, the second nut seat 24, and the second guide seat 25 to form a cross connecting frame 19. Moreover, a connecting seat 23 is fixed on one side of the second positioning plate 16, and the connecting seat 23 and the first guide seat 22 are also connected by a connecting rod 21. The connecting seat 23 is located in the middle of the two second positioning plates 16 close to one end, and the second screw 14 passes through the connecting seat 23, and a gap is left between the second screw 14 and the connecting seat 23.

[0036] A first positioning plate 10 is respectively provided at both ends of the first screw rod 12, the first guide rod 9 is fixedly connected to the first positioning plate 10, the first screw rod 12 is rotatably connected to the first positioning plate 10, a first motor 11 is provided on the first positioning plate 10, an end of the first screw rod 12 is connected to the working end of the first motor 11, a second motor 15 is provided on the second positioning plate 16, and an end of the second screw rod 14 is connected to the working end of the second motor 15.

[0037] The first positioning plate 10 is fixedly installed inside the inner shell, and the first motor 11 drives the first screw 12 to rotate forward or reverse. The second motor 15 is fixedly installed on the second positioning plate 16, and the second motor 15 drives the second screw 14 to rotate forward or reverse. At the same time, a guide rail 17 is also arranged in the horizontal direction on one side of the second positioning plate 16. The guide rail 17 is fixedly installed inside the inner shell, and a slider is installed in the guide rail 17. The slider is fixedly connected to the second positioning plate 16, thereby improving the stability of the movement of the second positioning plate 16.

[0038] The shell 1 includes an outer shell and an inner shell (not shown in the figure), a buffer pad is arranged between the outer shells, and a main control area 3 and a camera area 4 are arranged inside the inner shell. The main control area 3 and the camera area 4 are separated by a partition 5, and the camera 2, the lateral displacement unit 7, and the longitudinal displacement unit 8 are installed in the camera area 4.

[0039] The structure of the outer shell and the inner shell is similar to that of the shell 1, the only difference is the size. The outer shell is mounted on the outside of the inner shell, and the buffer pad can be a hard sponge pad or a silicone pad. When the recorder is bumped or dropped, the buffer pad acts as a shock absorber to reduce the impact force generated by the external impact on the inner shell and its internal structure, thereby protecting its internal structure and reducing the risk of damage.

[0040] In the present application, camera holes are provided at the front ends of the inner shell and the outer shell, sealant is applied between the edges of the camera hole of the inner shell and the camera hole of the outer shell, a lens glass is installed on the camera hole of the inner shell, and camera 2 is installed behind the lens glass.

[0041] A control main board is arranged inside the partition 5 , and a gyroscope sensor and an acceleration sensor are arranged on the control main board. The gyroscope sensor and the acceleration sensor are electrically connected to the lateral displacement unit 7 and the longitudinal displacement unit 8 .

[0042] The control main board is also equipped with a microprocessor, a key switch, a power switch, etc., including a gyro sensor and an acceleration sensor, which are all mature existing technologies. Their detailed structures are not repeated here. As for the gyro sensor and the acceleration sensor, the gyro sensor is mainly used to detect the moving direction of the recorder with the law enforcement personnel during the movement, while the acceleration sensor is used to detect the movement acceleration in this direction. After receiving the above two detection data, the main components such as the microprocessor of the control main board calculate the compensation amount required by the camera 2, and send the parameters to the first motor 11 or the second motor 15 to control the direction, speed and number of rotations of the first motor 11 or the second motor 15 (the two can also run at the same time), so as to accurately adjust the position of the camera 2 for position compensation and improve the anti-shake effect.

[0043] A battery compartment is provided inside the partition 5, and a battery is provided in the battery compartment. The battery is electrically connected to the control mainboard.

[0044] The battery can be a dry cell or a storage battery. The battery supplies power to the camera 2, the first motor 11, the second motor 15, the gyroscope sensor, the acceleration sensor and other components through the control mainboard.

[0045] Working principle: When in use, the gyroscope sensor is used to detect the direction in which the recorder moves with the law enforcement personnel, and the acceleration sensor is used to detect the movement acceleration of the recorder in the above-mentioned moving direction with the law enforcement personnel. When lateral displacement occurs, the control mainboard calculates the above-mentioned data and then sends a signal to the first motor 11, controls the first motor 11 to drive the camera 2 to make position compensation in the opposite direction. When longitudinal displacement occurs, the control mainboard controls the second motor 15 to drive the camera 2 to make position compensation in the opposite direction. According to the situation, signals can also be sent to the first motor 11 and the second motor 15 at the same time to drive the camera 2 to move in the inclined direction, thereby improving the image jitter of the recorder during shooting.
