Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to fig. 1 to 5 in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application. It is to be understood that the drawings are designed solely for the purposes of illustration and not as a definition of the limits of the application. The connection relationships shown in the drawings are for convenience of clarity of description only and are not limiting on the manner of connection.
The embodiment of the application discloses a law enforcement recorder integrated helmet. Referring to fig. 1, the law enforcement recorder integrated helmet includes a helmet shell 1 and a camera module 2, and the camera module 2 is provided at the front end of the outside of the helmet shell 1, so that the camera module 2 is positioned in front of the head when a person wears the law enforcement recorder integrated helmet. Specifically, helmet shell 1 has certain thickness, has seted up installation cavity 11 at the front end in helmet shell 1 outside, and camera module 2 is arranged in the installation cavity 11 inside. The inside of the installation cavity 11 is also provided with an elastic coil spring 13 with elasticity, the elastic coil spring 13 is approximately in a 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 the elastic coil spring 13, the connection between the camera module 2 and the inner wall of the installation cavity 11 is not rigid, so that the vibration of the helmet shell 1 is not directly transmitted to the camera module 2, the elastic coil spring 13 absorbs partial vibration energy and plays a damping role, so that the vibration of the camera module 2 is reduced, the camera module 2 is kept in a relatively stable state in the process of acquiring images, and the problems of fuzzy distortion of images and videos acquired by law enforcement recorders are solved.
Referring to fig. 1 and 2, the camera module 2 in this embodiment 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 plays a role in optical imaging, and the photosensitive imaging unit plays a role in converting an optical image into an electrical signal convenient for signal transmission, and this part is not described herein again because it is the prior art.
Referring to fig. 1, the stiffness coefficient of the elastic coil spring 13 of the above-described elastic coil spring 13 increases from the periphery to the center. The greater the stiffness coefficient, the greater the energy absorbed by the deformation per unit length. Therefore, when the helmet shell 1 is vibrated, part of the 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, the energy absorbed by the elastic coil spring 13 when the vibration is transmitted to the center of the elastic coil spring 13 needs to be larger and larger, but the energy transmitted to the elastic coil spring 13 from the helmet shell 1 is gradually attenuated after being absorbed by the elastic coil spring 13, so that when the energy transmitted to the center of the elastic coil spring 13 is small, the energy of the vibration is insufficient to deform the position of the elastic coil spring 13 close to the center, and therefore, the elastic coil spring 13 plays a role of absorbing the vibration, 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 relatively 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 kept in a relatively stable state, and is easier to recover to a stable state in vibration. In this embodiment, the integral helmet of law enforcement recorder is wearing the in-process, and the central axis and the gravity direction of elasticity coil spring 13 are roughly mutually perpendicular, so set up can play comparatively showing the regulation effect to the vibration from vertical direction. In another embodiment, the elastic coil spring 13 can be additionally provided with a central axis parallel to the gravity direction, so that a remarkable adjusting effect on vibration from the horizontal direction can be achieved. In other embodiments, the elastic coil spring 13 may be provided with more than two, so that the center of gravity of the camera module 2 is always on the central axis of the elastic coil spring 13, so that the vibration resistance of the camera module 2 can be improved, and the stability of the camera module 2 can be improved.
Referring to fig. 1, further, the elastic coil spring 13 can be regarded as a continuous wire shape formed by connecting plural 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, the elastic coil spring 13 is in an archimedean spiral shape, and thus, the energy absorption of the elastic coil spring 13 is relatively uniform.
In another embodiment, the coil interval of each turn of the elastic coil spring 13 is narrowed from the periphery to the center, and specifically, the elastic coil spring 13 may have a substantially equiangular spiral shape. So configured, 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 deforms; the direction of vibration is opposite to the direction in which the elastic coil spring 13 resumes deformation, thereby helping to cancel 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 effects of each turn of coils in the elastic coil spring 13 are ensured.
Referring to fig. 1, in order to shorten the time from vibration to stabilization of the camera module 2, the magnet blocks 21 are adhered or otherwise fixed to opposite sides of the outer side of the camera module 2, and the magnet blocks 21 may be permanent magnets, and may have a substantially circular, square or other shape; correspondingly, the inner wall of the installation cavity 11 is also adhered or otherwise fixed with the magnetic blocks 22 at two opposite sides, the magnetic blocks 22 can be permanent magnets, and the ends with the same polarity of the magnetic blocks 22 and the magnetic blocks are arranged close to each other, so that the magnetic attraction blocks 21 and the magnetic blocks 22 are attracted to each other; and the center connecting line of the magnetic block 22 and the center of the magnetic block 21 passes through the center of gravity of the camera module 2, so that attractive forces generated by the magnetic block 21 and the magnetic block 22 on 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 connecting line between the centers of the two magnetic blocks 22 and the center of the magnetic attraction block 21 is parallel to the horizontal direction, so that the two groups of attraction forces are parallel to the horizontal direction, and when vibration in the vertical direction occurs, the force in the magnetic field can guide the camera module 2 to the original position, so that the time from vibration to stabilization of the camera module 2 is shortened.
Referring to fig. 1, further, a circular spring 23 is provided between the magnetic block 22 and the magnet block 21. Specifically, one end of the circular spring 23 is abutted against the inner wall of the mounting cavity 11, the other end is abutted against the outer side of the camera assembly, and the magnetic block 22 and the magnetic attraction block 21 are respectively positioned in coils at two ends of the circular spring 23; the ends of the circular springs 23 may be secured to the outside of the camera head assembly or to the inner wall of the mounting cavity 11 by welding, clamping or other means of secure connection. The central axis of the circular spring 23 penetrates through the center of gravity of the camera module 2, and at the moment, the central axis of the circular spring 23 is also coincident with the connecting line of the center of the magnetic block 22 and the center of the magnetic attraction block 21. The circular spring 23 has a function of restoring deformation and plays a role of supporting to a certain extent, so that when the camera module 2 vibrates in the vertical direction, the circular spring 23 swings, and 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 swings towards the central axis of the circular spring 23; when one end of the circular spring 23 swings to be coaxial with the central axis of the circular spring 23, the circular spring 23 tends to be stable under the action of attractive force between the magnetic block 22 and the magnetic attraction block 21, so that the circular spring 23 has the function of guiding the vibrating camera module 2 to return to a stable state, and the camera module 2 is easier to be stable.
Referring to fig. 2, the opening edge of the installation cavity 11 is provided with a transparent protective cover 12, and the transparent protective cover 12 may be fixed to the opening edge of the installation cavity 11 by an adhesive. The mohs hardness of the transparent shield 12 is greater than 5.5. Referring to the Mohs hardness table, the hardness of some common substances, such as skin, is 1.5; the hardness of the ice cubes is 2-3; nail hardness was 2.5; the hardness of gold, silver and aluminum is 2.5-3; copper hardness was 3; the hardness of iron is 4-5; the hardness of glass and stainless steel was 5.5. The transparent shield 12 of the present application is harder than stainless steel and glass and thus can provide scratch resistance. 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 image quality obtained by the camera module 2 is high, and the blur is not easy to occur. Further, in conjunction with fig. 3, for aesthetic purposes, the surface of the transparent protective cover 12 may be further provided with a layer of shielding cover with a hole in the middle, for shielding the elastic coil spring 13, where the area of the hole is generally larger than the cross-sectional area of the camera module 2, so that the camera module 2 can still acquire an image without shielding when vibrating.
Referring to fig. 4, the inner side of the helmet shell 1 is provided with an elastic inner net 4 through a buffer bracket 3, the elastic inner net 4 is in a cambered surface shape, and has meshes which have ventilation function, thereby being beneficial to improving the comfort of the wearer. The buffer support 3 comprises an arc-shaped support bar 31, wherein the arc-shaped support bar 31 is arc-shaped, and at least two support columns 32 are penetrated and arranged in the arc-shaped support bar 31. In this embodiment, the support columns 32 and the arc-shaped support bars 31 may be integrally formed by injection molding. Referring to fig. 5, one end of the support post 32 abuts against the inner wall of the helmet shell 1, and specifically, the support post may be fixed by adhesion or clamping. The other end of the support column 32 is provided with a guide blind hole 322, and an inner limit ring 321 is integrally formed on the inner wall of the opening of the guide blind hole 322 of the support column 32; the guide blind hole 322 is internally provided with a guide column 33 in a sliding manner, one end, facing the guide hole, of the guide column 33 is provided with a limiting counter bore 332, and an outer limiting ring 331 is integrally formed on the outer periphery side of the opening end of the limiting counter bore 332, of the guide column 33.
