Description

Technical Field

[0001] This invention relates to the field of surveillance equipment technology, and in particular to a camera vibration reduction structure. Background Technology

[0002] Existing tube cameras typically use gimbal brackets to connect to external equipment platforms. In this connection method, the tube camera, gimbal bracket, and equipment platform are usually rigidly connected, lacking vibration damping measures and only suitable for installation on stationary equipment platforms. To accommodate the installation of tube cameras on vibrating equipment platforms, rubber pads are usually placed between the gimbal bracket and the equipment platform for vibration damping. However, because the rubber pads are located at the bottom, they can only provide vibration damping in a single direction, and their effectiveness is poor for multi-degree-of-freedom vibrations. Summary of the Invention

[0014] Optionally, the two vertical sidewalls of the universal bracket are provided with protruding column structures, and the connecting baffle is provided with guide grooves adapted to the protruding column structures.

[0015] Optionally, the groove of the mounting module divides the upper surface of the mounting module into two planar regions; each planar region corresponds horizontally to the corresponding planar region in the fixed base through blind holes and pins; each planar region limits vertical displacement to the corresponding planar region in the fixed base through vertically arranged connectors.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] This invention provides a camera vibration reduction structure, such as... Figure 1-5 As shown, it includes:

[0039] The mounting base 4 has two spaced-apart mounting modules that are fixedly connected; in some embodiments, the mounting base 4 can be fixedly connected to the machine tool. The mounting modules can be, for example, in the form of bosses. The two mounting modules are connected by a connecting plate or connecting block.

[0040] The fixed base 3 has two connecting modules corresponding to the two mounting modules, and the two connecting modules are fixedly connected. The connecting modules and the mounting modules correspond to each other in horizontal position through blind holes and pins 7. A horizontal damping device 8 is provided between the blind holes and pins 7. The mounting modules and the connecting modules limit vertical displacement through vertically arranged connectors. A vertical damping device 9 is connected in series with the connectors. In some embodiments, the horizontal damping devices 8 of the connecting modules and the mounting modules can be set in different forms. One is to set blind holes on the connecting modules and blind holes or through holes that cooperate with pins 7 on the mounting modules, and set horizontal damping devices 8 between the blind holes of the connecting modules and pins 7. Another is to set blind holes on the mounting modules and blind holes or through holes that cooperate with pins 7 on the connecting modules, and set horizontal damping devices 8 between the blind holes of the mounting modules and pins 7. Yet another is to set horizontal damping devices 8 between the blind holes of the mounting modules and the connecting modules and pins 7. Setting a horizontal damping device 8 between the blind hole and the pin 7 means that the horizontal damping device 8 has a through hole, is placed in the blind hole, and then the pin 7 is inserted into the through hole of the horizontal damping device 8. The horizontal damping device 8 can be, for example, a rubber ring with equal height. The vertically set connecting part 6 can be, for example, a screw or bolt, and the vertical damper can be, for example, a multi-layer rubber pad or a rubber ring with equal height.

[0041] The universal bracket 2 is disposed within the interval between the two connecting modules. The universal bracket 2 has a cylindrical structure with a quadrilateral interface. The two vertical sidewalls of the universal bracket 2 are rotatably connected to the connecting modules, and the two horizontal sidewalls of the universal bracket 2 are used for fixed connection to the cylindrical camera 1. In some embodiments, the rotatable connection between the vertical sidewalls of the universal bracket 2 and the connecting modules enables the angle adjustment of the cylindrical camera 1, making the entire camera vibration reduction structure applicable to more scenarios.

[0042] In the technical solution provided by this invention, a horizontal damping device 8 is arranged between the blind hole and the pin 7, and a vertical damping device 9 is connected in series on the vertically arranged connector. This method can achieve the dispersion and absorption of vibrations in any direction. The horizontal damping device 8 is arranged around the pin 7 in the blind hole, thus effectively absorbing vibrations in any direction within a 360-degree range in the horizontal plane. The vertical damping device 9 effectively absorbs vibrations in the vertical direction. Through effective absorption and dispersion of vibrations, the clarity of the video image and the product's lifespan can be improved, enabling monitoring in camera vibration scenarios and ensuring the safety of equipment operation. Furthermore, the technical solution provided by this invention adopts a modular design, facilitating assembly and adjustment of the entire unit. In some preferred embodiments, a decorative cover 5 can also be provided above the universal bracket 2. The decorative cover 5 enhances the overall integration and aesthetics of the unit and provides some protection and shielding for the camera.

[0043] As an optional implementation method, such as Figures 6-7 As shown, a groove penetrating the mounting module is provided in the middle of the upper surface of the mounting module, and the grooves of the two mounting modules are coaxially arranged.

[0044] The connecting module is a housing adapted to the shape of the outer surface of the mounting module; a connecting baffle is provided in the groove of the connecting module;

[0045] The universal bracket 2 is rotatably connected to the connecting baffle.

[0046] In some embodiments, a groove is provided on the upper surface of the mounting module, and the connecting module also has a corresponding groove. This groove serves several purposes: firstly, it effectively reduces the weight of the upper part of the camera's vibration-damping structure, lowering its center of gravity and reducing swaying; secondly, it effectively lowers the camera's mounting height, further reducing the center of gravity of the entire structure; and thirdly, it provides ample assembly space for the connection between the universal bracket 2 and the connecting module, facilitating installation. Using this embodiment, the rotation center of the universal bracket can be positioned as close as possible to the camera's center of gravity, which is more conducive to reducing the impact of vibration. This also indirectly reduces the overall height of the vibration-damping structure, thus improving vibration reduction.

[0047] As an optional implementation, the connecting baffle is provided with an arc-shaped hole and a rotating connecting hole;

[0048] The universal bracket 2 is provided with a rotating connection hole and multiple locking holes arranged in an arc;

[0049] When the universal bracket 2 rotates relative to the fixed base 3, the rotation trajectory of the multiple locking holes arranged in an arc is coaxial with the rotation trajectory of the arc-shaped holes and has the same radius.

[0050] In some embodiments, the rotating connection holes provided on the connecting baffle and the universal bracket 2 enable the rotating connection between the connecting baffle and the universal bracket 2. The locking holes with arc-shaped holes and arc-shaped arrangement have a coaxial and the same radius rotation trajectory, so that within the effective rotation angle, at least one locking hole can always cooperate with the arc-shaped hole to lock the rotation between the connecting baffle and the universal bracket 2.

[0051] As an optional implementation, the two vertical sidewalls of the universal bracket 2 are provided with protruding post structures, and the connecting baffle is provided with guide grooves adapted to the protruding post structures. In some embodiments, the guide groove refers to a groove machined on the side of the connecting baffle facing the universal bracket 2, which has an opening at the top of the connecting baffle to allow the protruding post structure to pass through for installation. At the other end of the groove, there is an arc-shaped sidewall adapted to the outer edge of the protruding post. The cooperation between the protruding post and the guide groove, and the cooperation and installation of the edge universal bracket 2 and the connecting baffle are all achieved.

[0052] As an optional implementation, continue as follows Figure 6-7 As shown, the groove of the mounting module divides the upper surface of the mounting module into two planar regions; each planar region corresponds horizontally to the corresponding planar region in the fixed base 3 through blind holes and pins 7; each planar region limits vertical displacement to the corresponding planar region in the fixed base 3 through vertically arranged connectors 6. The interval between the two mounting modules and the groove on each mounting module divides the entire mounting base 4 into four planar regions, which are located near the corners of the mounting base 4. This method can effectively increase the distance between the horizontal damping devices 8 and the vertical damping devices 9, effectively reducing camera shake. Since horizontal vibration is less sensitive to the distance between the damping devices than vertical vibration, the horizontal damping devices 8 can be placed closer to the universal bracket 2, while the vertical damping devices 9 can be placed further away from the universal bracket 2.

[0053] As an optional implementation, continue as follows Figure 4As shown, the connecting module and the mounting module are fitted with a clearance, and the clearance between the bottom of the connecting module and the mounting module's side wall is greater than the clearance between the top of the side wall. In some embodiments, when the bottom clearance is greater than the top side wall clearance, assembly is easier and the assembly difficulty is reduced.

[0054] As an optional implementation, continue as follows Figure 3 As shown, the two mounting modules are fixedly connected by a first intermediate member with a cross-sectional shape having a central arch, the axis of which is parallel to the arrangement direction of the two mounting modules.

[0055] The two connection modules are fixedly connected by a second intermediate component, which has a matching shape with the first intermediate component.

[0056] In some embodiments, the use of a cross-sectional shape with a central arch allows for greater space at the front and rear of the camera's vibration damping structure, facilitating angle adjustments for both overhead and under-the-head views. For example, Figure 10 In the middle, the camera is set horizontally, while Figure 11 In this case, setting the camera at a low angle requires more space behind it, and Figure 12 If the camera is positioned at a top-down angle, a larger space is required in front of it.

[0057] In one optional implementation, the upper surface of the horizontal damping device 8 is spaced apart from the lower surface of the connecting module; the vertical damping device 9 is pressed together by the mounting module and the connecting module. In some embodiments, when the equipment platform vibrates, the vibration is transmitted to the mounting base 4. The vertical vibration can be effectively reduced by the vertical damping device 9; the horizontal vibration reduction is achieved by the pin 7 pressing the horizontal damping device 8 back and forth. Specifically, a gap is left between the horizontal damping device 8 and the fixed base 3. This allows the horizontal damping device 8 to handle horizontal vibration reduction when vibration is transmitted, while the vertical damping device 9, pressed together with the fixed base 3, can handle vertical vibration reduction. The two rubber rings do not interfere with each other, thus achieving a better effect.

[0058] As an optional implementation method, such as Figure 8-9 As shown, one of the vertical sidewalls and one of the horizontal sidewalls of the universal bracket 2 form a first sub-bracket 21;

[0059] The other vertical sidewall and the other horizontal sidewall of the universal bracket 2 form a second sub-bracket 22;

[0060] The first sub-bracket 21 and the second sub-bracket 22 are detachably connected.

[0061] In some embodiments, the connection between the first sub-support 21 and the second sub-support 22 can be made through a waist-shaped hole, which can adjust the height of the drum machine up and down, thereby adapting to different drum machines and improving the compatibility of the vibration damping mechanism.

[0062] As an optional implementation, continue as follows Figure 8-9 As shown, a detachable counterweight is provided on the horizontal side wall of the universal bracket 2. In some embodiments, the use of the counterweight can be selected according to the specific scenario; the counterweight can be used to adjust the weight of the whole machine, change its center of gravity position, find the most favorable conditions for vibration reduction, and make the camera more stable when vibrating. If the center of gravity of the equipment is too high, it will amplify the shaking of the platform, which is not conducive to vibration reduction.

[0063] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
