Description
Technical Field
[0001] The utility model relates to the technical field of law enforcement equipment, in particular to an anti-fall and anti-shake law enforcement recorder. Background Art
[0002] The law enforcement video recorder is a single-soldier law enforcement equipment, suitable for use by all types of police and law enforcement departments. It has the main functions of digital video, digital photography, and transmitter, as well as some auxiliary functions such as positioning. With the continuous development of social economy and the continuous advancement of science and technology, high-sensitivity law enforcement video recorders have also been born. High-sensitivity law enforcement video recorders have more intelligent functions and more stable and sensitive transmission signals.
[0003] In the prior art, traditional law enforcement cameras will shake as the body shakes when shooting, which often causes the recorder's shooting picture to shake severely and cannot be seen clearly, which is not enough to serve as a basis for later evidence collection. When running, moving limbs or making physical contact with the other party, the captured picture will be severely shaken and blurred, making it impossible for the captured picture to clearly record the true situation of the incident. If the video needs to be used as evidence at this time, it will lose its meaning as evidence due to the severe shaking and blur. Utility Model Content
[0004] The utility model aims to solve the shortcomings in the prior art and proposes an anti-fall and anti-shake law enforcement recorder.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a protective shell, the upper end face of the protective shell is provided with a sealing cover, the interior of the protective shell is provided with a camera, the front end face of the camera is fixed with a voice coil motor, the front end face of the voice coil motor is fixed with a sleeve, the front end face of the sleeve is fixed with an infrared filter, the interior of the camera is provided with a gyroscope, the inner wall of the voice coil motor is fixed with a magnetic coil, the interior of the voice coil motor is provided with a suspended fixed block, the outer surface of the suspended fixed block is fixed with an induction coil, the front end face of the suspended fixed block is fixed with a shooting lens, the suspended fixed block is suspended inside the magnetic coil through the induction coil. In the prior art, traditional law enforcement instruments will shake with the shaking of the body when shooting, which often causes the shooting picture of the recorder to shake violently and seriously, and the picture cannot be seen clearly and is not enough for later recording. The basis of evidence, due to running, limb movement or physical contact with the other party, the captured picture will be severely shaken and blurred, making it impossible for the captured picture to clearly record the true situation of the event. If the video needs to be used as evidence at this time, it will lose its meaning as evidence due to severe shaking and blurring. The gyroscope inside the camera detects tiny movements and then transmits the signal to the microprocessor. The processor immediately calculates the displacement that needs to be compensated, and then drives the fixed suspension block to perform displacement compensation through adjustment between the induction coil and the magnetic coil, thereby driving the shooting lens on the fixed suspension block to perform displacement compensation, and compensates according to the shaking direction and displacement of the lens, thereby effectively overcoming the image blur caused by the vibration of the camera, thereby achieving anti-shake for the shooting lens, allowing law enforcement officers to shake the recorder significantly.
[0006] Preferably, a buffer pad is provided inside the protective shell, a fixing knob is fixed at the bottom of the inner wall of the protective shell, a connecting plate is fixed to the inner wall of the protective shell through the fixing knob, buffer springs are fixed on both sides of the upper end of the connecting plate, and a fixing buckle is fixed on the upper end surface of the buffer spring, and the surface of the fixing buckle is detachably connected to the bottom end surface of the camera. Nowadays, law enforcement officers use handheld recorders to enforce the law. Once a dispute occurs between the two parties during law enforcement, a single police law enforcement audio and video recorder is prone to fall to the ground, resulting in damage and inability to continue to collect evidence. Especially during the law enforcement and arrest process, physical contact may occur with the criminals, causing the law enforcement recorder to fall and be damaged, making it impossible to retrieve the on-site image data afterwards, which increases the difficulty of evidence collection for police officers. By fixing the camera and the buffer spring and placing them in the protective shell, when it falls, the buffer spring buffers the impact, and the buffer pad inside the protective shell absorbs the impact, thereby realizing the anti-fall function of the law enforcement instrument.
[0007] Preferably, a fixing plate is fixed to the back of the protective shell, a fixing bolt is fixed to the surface of the fixing plate, a pressure plate is fixed to the outer surface of the fixing plate by the fixing bolt, a buffer ring is fixed to the bottom end face of the fixing bolt by the pressure plate, and a clamp is fixed to the bottom front end of the pressure plate. Nowadays, during the use of the law enforcement instrument, personnel are sometimes not equipped with pockets, especially in hot summer, which makes the law enforcement instrument inconvenient to carry. At the same time, when chasing criminals, the law enforcement recorder needs to be held in hand, which is inconvenient to catch criminals and increases the cost of using the law enforcement instrument. The utility model installs a splint on the back of the protective shell, and fixes the clothes of the law enforcement personnel between the fixing plate and the pressure plate by using the clamp at the front end of the pressure plate, and fixes the law enforcement instrument on the clothes, thereby realizing that the law enforcement instrument is fixed on the collar and waist of the clothes, making it more convenient to carry the law enforcement instrument.
[0008] Preferably, a drain port is provided at the bottom end of the protective shell, and water accumulation is prevented through the drain port, thereby preventing water stains from accumulating inside the law enforcement instrument.
[0009] Preferably, the buffer pad material is flexible rubber, and the softness of the flexible rubber can reduce the damage caused by collision between the camera and the buffer rubber.
[0010] Preferably, the top of the camera is arc-shaped, and by setting the outer shape in an arc shape, it is possible to avoid water stains from accumulating on the upper end of the camera.
[0011] Preferably, the buffer ring is made of a stainless steel metal ring, which is corrosion-resistant, thereby extending the life of the metal ring and avoiding damage due to corrosion.
[0012] Beneficial Effects
[0013] 1. In the prior art, traditional law enforcement devices will shake with the shaking of the body when shooting, which often causes the recording screen to shake violently and seriously. When the screen is not clear, it is not enough to serve as the basis for later evidence collection. When running, moving limbs or making physical contact with the other party, the captured screen will be severely shaken and blurred, so that the captured screen cannot clearly record the true situation of the event. If the video needs to be used as evidence at this time, it loses its meaning as evidence due to severe shaking and blurring. The utility model detects tiny movements through the gyroscope inside the camera, and then transmits the signal to the microprocessor. The processor immediately calculates the displacement that needs to be compensated, and then drives the fixed suspension block to perform displacement compensation through the adjustment between the induction coil and the magnetic coil, thereby driving the shooting lens on the fixed suspension block to perform displacement compensation, and compensates according to the shaking direction and displacement of the lens, thereby effectively overcoming the image blur caused by the vibration of the camera, thereby realizing anti-shake for the shooting lens, so that the law enforcement officer can shake the recorder significantly.
[0014] 2. Nowadays, law enforcement officers carry handheld recorders to enforce the law. Once a dispute occurs between the two parties during law enforcement, the single police law enforcement audio and video recorder is easily dropped to the ground, resulting in damage and inability to continue to collect evidence. Especially during the law enforcement and arrest process, physical contact with criminals may occur, causing the law enforcement recorder to fall and be damaged, making it impossible to retrieve on-site video data afterwards, which increases the difficulty for police officers to collect evidence. The utility model fixes the camera and the buffer spring and places them in a protective shell. When it falls, the buffer spring buffers the impact, and the buffer pad inside the protective shell absorbs the impact, thereby realizing the anti-fall function of the law enforcement instrument.
[0015] 3. Nowadays, when using law enforcement devices, personnel are sometimes not equipped with pockets, especially in hot summer, which makes the law enforcement devices inconvenient to carry. At the same time, when chasing criminals, the law enforcement recorder needs to be held in hand, which is inconvenient to catch criminals and increases the cost of using the law enforcement device. The utility model installs a splint on the back of the protective shell, fixes the clothes of the law enforcement personnel between the fixing plate and the pressing plate by means of the clamping head at the front end of the pressing plate, and fixes the law enforcement device on the clothes, so that the law enforcement device is fixed on the collar and waist of the clothes, making it more convenient to carry the law enforcement device.
