Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings 1 to 5 in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application. It is to be understood that the drawings are provided solely for the purposes of reference and illustration and are not intended as a definition of the limits of the invention. The connection relationships shown in the drawings are for clarity of description only and do not limit the manner of connection.
The embodiment of the application discloses integrative helmet of law enforcement record appearance. Referring to fig. 1, integrative helmet of law enforcement record appearance includes helmet shell 1 and camera module 2, and camera module 2 establishes the front end in the helmet shell 1 outside for the personnel are when wearing the integrative helmet of law enforcement record appearance, and camera module 2 is located the place ahead of head. Specifically, the helmet shell 1 has a certain thickness, the front end of the outer side of the helmet shell 1 is provided with the installation cavity 11, and the camera module 2 is arranged in the installation cavity 11. An elastic coil spring 13 with elasticity is further arranged in the installation cavity 11, the elastic coil spring 13 is in a substantially flat spiral line shape, the edge of the elastic coil spring 13 far away from the center is defined as the periphery, the periphery of the elastic coil spring 13 is fixed with the inner wall of the installation cavity 11, the center of the elastic coil spring 13 is fixed with the camera module 2, and the specific fixing mode can be screw fixing, clamping fixing, bonding fixing or welding fixing. Under the effect of elasticity coil spring 13, camera module 2 is not rigid connection with being connected between the 11 inner walls of installation cavity, therefore the vibration of helmet shell 1 can not directly transmit camera module 2, elasticity coil spring 13 has absorbed the energy of partial vibration, the effect of damping has been played, consequently, camera module 2's vibration has been reduced, make camera module 2 keep in comparatively stable state at the in-process of acquireing the image, thereby the image that law enforcement record appearance acquireed, the fuzzy problem of distortion of video has been improved.
Referring to fig. 1 and 2, in this embodiment, the camera module 2 may include a lens barrel, an optical imaging lens disposed in the lens barrel along a main optical axis, and a photosensitive imaging unit, where the optical imaging lens performs an optical imaging function, and the photosensitive imaging unit performs a function of converting an optical image into an electrical signal for facilitating signal transmission, and as this part is the prior art, details are not repeated here.
Referring to fig. 1, the stiffness coefficient of the elastic coil spring 13 described above increases from the periphery to the center. The greater the stiffness coefficient, the greater the energy absorbed to produce deformation per unit length. Therefore, when the helmet shell 1 is vibrated, part of vibration is transmitted to the periphery of the elastic coil spring 13, so that the periphery of the elastic coil spring 13 starts to absorb the vibration, and as the vibration is transmitted to the center of the elastic coil spring 13, the energy absorbed by the vibration caused by the elastic coil spring 13 needs to be larger and larger, but the energy transmitted from the helmet shell 1 to the elastic coil spring 13 is gradually attenuated after being absorbed by the elastic coil spring 13, so that when the vibration is transmitted to the center of the elastic coil spring 13, the energy of the vibration is already small and is not enough to deform the position of the elastic coil spring 13 close to the center, and therefore, the elastic coil spring 13 plays a role in absorbing the vibration in the application, so that the position of the camera module 2 is kept in a stable state.
Referring to fig. 1, further, the center axis of the elastic coil spring 13 passes through the center of gravity of the camera module 2. The above analysis shows that the center of the elastic coil spring 13 is stable, so that the center of gravity of the camera module 2 coincides with the center of the elastic coil spring 13, so that the camera module 2 is maintained in a stable state, and is easily restored to a stable state in vibration. In the embodiment, when the law enforcement recorder integrated helmet is worn, the central axis of the elastic coil spring 13 is approximately perpendicular to the gravity direction, so that the law enforcement recorder integrated helmet can play a remarkable adjusting effect on the vibration from the vertical direction. In another embodiment, the elastic coil spring 13 may be added with its central axis parallel to the gravity direction, which may provide a more significant adjustment effect for the vibration from the horizontal direction. In other embodiments, the elastic coil spring 13 may be provided with more than two, so as to ensure that the center of gravity of the camera module 2 is always on the central axis of the elastic coil spring 13, thereby improving the anti-vibration performance of the camera module 2 and the stability of the camera module 2.
Referring to fig. 1, further, the elastic coil spring 13 may be considered as a continuous wire shape formed by connecting a plurality of turns of coils having different diameters end to end. In one embodiment, the distance between two adjacent turns of the elastic coil spring 13 is approximately equal, and the elastic coil spring 13 is in an Archimedes spiral shape, so that the energy absorption of the elastic coil spring 13 is uniform.
In another embodiment, the coil space of each turn of the elastic coil spring 13 is reduced from the periphery to the center, and specifically, the elastic coil spring 13 may have a substantially equiangular spiral shape. With this arrangement, when the energy of the vibration is transmitted from the helmet shell 1 to the elastic coil spring 13, the elastic coil spring 13 absorbs part of the energy and is deformed; the direction of vibration is opposite to the direction of restoring deformation of the elastic coil spring 13, thereby helping to offset the energy of vibration; the periphery of the elastic coil spring 13 has a larger vibration space, so that rigid collision between adjacent coils of the elastic coil spring 13 is reduced, the condition that energy is directly transmitted to the center of the elastic coil spring 13 is further reduced, and the buffering and vibration reduction effect of each turn of coil in the elastic coil spring 13 is ensured.
Referring to fig. 1, in order to shorten the time from vibration to stabilization of the camera module 2, magnetic blocks 21 are adhered or otherwise fixed to opposite sides of the outer side of the camera module 2, and the magnetic blocks 21 may be permanent magnets, and may be substantially circular, square or other shapes; correspondingly, the inner wall of the installation cavity 11 is also bonded or otherwise fixed with the magnetic block 22 at two opposite sides, the magnetic block 22 may be a permanent magnet, and the ends of the magnetic block 22 and the magnetic block with the same polarity are arranged close to each other, so that the magnetic block 21 and the magnetic block 22 attract each other; and the center of the magnetic block 22 and the center connecting line of the magnetic block 21 pass through the gravity center of the camera module 2, so that the attractive forces generated by the magnetic blocks 21 and 22 at the two sides of the camera module 2 are equal in magnitude and opposite in direction, and the two forces are kept in static balance. In this embodiment, the center of the two magnetic blocks 22 and the center line of the magnetic block 21 are parallel to the horizontal direction, so that the two sets of attraction forces are parallel to the horizontal direction, and when the vertical vibration occurs, the force in the magnetic field can guide the camera module 2 to the original position, thereby shortening the time from the vibration to the stabilization of the camera module 2.
Referring to fig. 1, a circular spring 23 is further disposed between the magnetic block 22 and the magnetic block 21. Specifically, one end of the circular spring 23 abuts against the inner wall of the mounting cavity 11, the other end abuts against the outer side of the camera assembly, and the magnetic block 22 and the magnetic block 21 are respectively located in coils at two ends of the circular spring 23; the end of the circular spring 23 may be fixed to the outside of the camera module or the inner wall of the mounting cavity 11 by welding, snapping or other fixing means. The central axis of the circular spring 23 passes through the center of gravity of the camera module 2, and at this time, the central axis of the circular spring 23 coincides with the connecting line of the center of the magnetic block 22 and the center of the magnetic block 21. The circular spring 23 has a function of restoring deformation and plays a role of supporting to a certain extent, so when the camera module 2 vibrates along the vertical direction, the circular spring 23 can swing, when one end of the circular spring 23 swings to deviate from the central axis of the circular spring 23, the circular spring 23 has a tendency of restoring deformation, and one end of the circular spring 23 can swing towards the central axis of the circular spring 23; when circular spring 23 one end swung to coaxial with the central axis of circular spring 23, under the appeal effect between magnetic block 22 and magnetism piece 21, circular spring 23 tended to stably, consequently circular spring 23 had the effect that the camera module 2 that the guide vibrates replied to stable condition for camera module 2 is changeed stably.
Referring to fig. 2, the transparent protective cover 12 is disposed at the opening edge of the mounting cavity 11, and the transparent protective cover 12 may be fixed to the opening edge of the mounting cavity 11 by an adhesive. The transparent shield 12 has a mohs hardness greater than 5.5. The hardness of some common substances can be known by consulting the Mohs hardness table, such as the hardness of the skin is 1.5; the hardness of the ice blocks is 2-3; nail hardness was 2.5; the hardness of gold, silver and aluminum is 2.5-3; the hardness of copper is 3; the hardness of the iron is 4-5; the hardness of glass and stainless steel is 5.5. The transparent shield 12 of the present application is greater than the hardness of stainless steel and glass, and therefore can function to resist scratching. In a specific embodiment, the transparent protective cover 12 may be made of quartz, and the hardness of the quartz reaches 7, so that the quality of the image obtained by the camera module 2 is high, and the situation of blurring is not easy to occur. With reference to fig. 3, further, for the sake of aesthetic appearance, the surface of the transparent protective cover 12 may further be provided with a shielding cover having an opening in the middle for shielding the elastic coil spring 13, and the area of the opening is generally larger than the cross-sectional area of the camera module 2, so that the camera module 2 can still obtain an image without shielding when generating vibration.
Referring to fig. 4, the elastic inner net 4 is disposed inside the helmet shell 1 through the buffering bracket 3, and the elastic inner net 4 is arc-shaped and has meshes, which have a ventilation function and contribute to improving the comfort of the wearer. The buffer support 3 comprises arc support bars 31, the arc support bars 31 are arc-shaped and at least two, and one, two or more support columns 32 are arranged in the arc support bars 31 in a penetrating manner. In this embodiment, the supporting columns 32 and the arc supporting bars 31 may be integrally formed by injection molding. Referring to fig. 5, one end of the support column 32 is abutted against the inner wall of the helmet shell 1, and the fixing can be realized by bonding or clamping.
