Description

Technical Field

[0001] This utility model relates to the field of anti-vibration brackets, and in particular to an anti-vibration bracket for a camera. Background Technology

[0002] During sugarcane processing, in conjunction with a fully automatic sugarcane cutter, a camera is needed to capture images, which are then processed by a computer system before issuing work commands to the power system. The camera installation requires a bracket, and to increase the camera's stability, a bracket with shockproof function is usually used.

[0003] Existing camera anti-vibration brackets typically use spring connections for shock absorption. However, due to the complex environment of sugarcane processing sites, while spring connections provide good shock absorption in the direction of the spring force perpendicular to the camera, they fail to provide shock absorption in the horizontal direction. Horizontal vibrations require the spring to twist and deform, which increases the amplitude of shaking and is therefore detrimental to the stability of the camera. Utility Model Content

[0004] The main purpose of this utility model is to provide a camera anti-vibration bracket that can effectively solve the technical problem that the traditional spring connection method in the background art causes the bracket to vibrate more violently in the horizontal direction.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A camera anti-vibration bracket includes a base, two horizontal aluminum profiles and three vertical aluminum profiles. The three vertical aluminum profiles are equidistantly installed between the two horizontal aluminum profiles, and each of the three vertical aluminum profiles has an anti-vibration structure between it and the base.

[0007] The shock-absorbing structure includes a lower fixing block and an upper fixing block, which are respectively connected to the base and the longitudinal aluminum profile, and a steel rope is connected between the lower fixing block and the upper fixing block.

[0008] As a further embodiment of this utility model, the steel rope is provided with four ropes, each of which is bent and expands outward.

[0009] As a further embodiment of this utility model, a through hole is provided at the center of both the lower fixing block and the upper fixing block, and a first bolt and a second bolt pass through the interior of both through holes. The first bolt is threadedly connected to the base, and the second bolt is threadedly connected to a slider.

[0010] As a further embodiment of this utility model, the slider is slidably connected to the longitudinal aluminum profile.

[0011] As a further embodiment of this utility model, a through groove is provided on the upper surface of the base at a position perpendicular to the space between the two longitudinal aluminum profiles.

[0012] As a further embodiment of this utility model, triangular connectors are provided at the connection points of the three longitudinal aluminum profiles and the two transverse aluminum profiles, and the triangular connectors are connected to the transverse aluminum profiles and the longitudinal aluminum profiles respectively by two screws.

[0013] The beneficial effects of this utility model are as follows: Four outwardly curved steel ropes form an asymmetric tension network, breaking through the traditional single-axis linear support mode of springs. Through the spatial distribution and tension coupling of the steel ropes, vibration energy in three directions (X / Y / Z) can be absorbed simultaneously, achieving three-dimensional dynamic vibration reduction. The bending shape of the steel ropes makes them exhibit variable stiffness characteristics under different displacement amplitudes. They provide high flexibility buffering at small amplitudes and strengthen the support stiffness through steel rope stretching at large amplitudes, avoiding the "rigid impact" problem caused by excessive compression of traditional springs.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Combination Figures 1-4A camera anti-vibration bracket includes a base 1, two horizontal aluminum profiles 2 and three vertical aluminum profiles 3. The three vertical aluminum profiles 3 are equidistantly installed between the two horizontal aluminum profiles 2, and each of the three vertical aluminum profiles 3 is provided with an anti-vibration structure 4 between itself and the base 1.

[0022] See Figure 1 and Figure 2 Furthermore, the shock-absorbing structure 4 includes a lower fixing block 5 and an upper fixing block 6, which are respectively connected to the base 1 and the longitudinal aluminum profile 3, and a steel rope 7 is connected between the lower fixing block 5 and the upper fixing block 6.

[0023] Specifically, the shock-absorbing structure 4 is set between the base 1 and the longitudinal aluminum profile 3. During use, it can effectively transmit vibration force between the base 1 and the longitudinal aluminum profile 3, reducing the impact on the camera installed on the transverse aluminum profile 2.

[0024] Example 2

[0025] See Figure 3 and Figure 4 Furthermore, based on Embodiment 1 and Embodiment 2, it is further found that there are four steel ropes 7, each of which is bent and expands outward. The center of the lower fixing block 5 and the upper fixing block 6 are provided with through holes 8. The first bolt 9 and the second bolt 12 pass through the interior of the two through holes 8. The first bolt 9 is threaded to the base 1, and the second bolt 12 is threaded to the slider 10. The slider 10 is slidably connected to the longitudinal aluminum profile 3. The upper surface of the base 1 is provided with a through groove perpendicular to the position between the two longitudinal aluminum profiles 3. The three longitudinal aluminum profiles 3 are provided with triangular connectors at the connection points with the two transverse aluminum profiles 2. The triangular connectors are connected to the transverse aluminum profiles 2 and the longitudinal aluminum profiles 3 respectively by two screws.

[0026] Specifically, during use, the weight of the horizontal aluminum profile 2 and the vertical aluminum profile 3 is pressed down on the steel rope 7 by the upper fixing block 6. The bent steel rope 7 generates elasticity due to the properties of steel. When vibration occurs, the steel rope 7 plays an excellent role in elastic energy absorption, reducing the transmission of vibration force.

[0027] It should be noted that this utility model is a camera anti-vibration bracket. In use, the first bolt 9 is used to pass through the through hole 8 of the lower fixing block 5 and connect to the base 1. The second bolt 12 is used to pass through the through hole 8 of the upper fixing block 6 and connect to the slider 10. Then, a workpiece with the same hook as the slider 10 is placed inside the horizontal aluminum profile 2 to install the camera. When vibration occurs, the steel rope 7 can play an excellent buffering role. The four outwardly bent steel ropes 7 form an asymmetric tension network, breaking through the traditional single-axis linear support mode of springs. Through the spatial distribution and tension coupling of the steel ropes 7, vibration energy in the three directions of X / Y / Z can be absorbed at the same time to achieve three-dimensional dynamic vibration reduction. The bending shape of the steel ropes 7 makes them exhibit variable stiffness characteristics under different displacement amplitudes. It provides high flexibility buffering at small amplitudes and strengthens the support stiffness through the stretching of the steel ropes 7 at large amplitudes, avoiding the "rigid impact" problem caused by excessive compression of traditional springs.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
