Description

Technical Field

[0001] The invention belongs to the field of camera technology, and in particular relates to a stabilizer for filming based on the Internet of Things. Background Art

[0002] Although the traditional camera stabilizer has a good stable shooting effect, it is large in size and expensive, and is not an option for ordinary people. Currently, there are small handheld stabilizers, which can only play a certain role in avoiding perspective shaking during ordinary camera movements. Under high-intensity exercises such as running and jumping, the traditional small handheld stabilizer is difficult to meet the stabilization effect. The main reason is that the small handheld stabilizer can mainly reduce the swing of the camera. When the arm is tilted, the camera can be kept from following the tilt and swing of the arm. However, when running and jumping, the traditional handheld small stabilizer cannot offset the large impact force generated by running and jumping. The large impact force generated by running and jumping is mainly concentrated in the direction perpendicular to the ground. When a large impact force is generated, the picture taken by the camera will shake violently, and effective shooting cannot be performed. Summary of the invention

[0027] In an optional embodiment, the inner side of the limit strip 93 is rotatably connected to a steel ball 94 , and the outer side of the steel ball 94 is rotatably connected to the inner side of one end of the control wheel 9 .

[0028] In this embodiment: the housing 6 is fixed on the photographer, for example, it can be installed on the head, chest or shoulder, but the bottom surface of the housing 6 needs to be level with the ground, that is, the moving trajectory of the counterweight housing 3 relative to the housing 6 needs to be perpendicular to the ground. When the photographer walks, the small vibration generated can be filtered by the anti-vibration foam 2. When the photographer runs or jumps, resulting in a large impact force, the counterweight housing 3 drives the camera 1 to move relative to the housing 6 through the anti-vibration foam 2 to reduce the impact force, and achieve more stable shooting; Take the jump and landing of the photographer as an example. The time taken for a person to jump and land varies due to individual differences, exercise status, physical fitness and other factors. Generally speaking, the time from the beginning of the jump to the feet leaving the ground is usually around 0.2 to 0.5 seconds. In this process, different people will have different jump times due to differences in muscle strength, reaction speed and other aspects. When landing, the time from the feet touching the ground to the body maintaining stability is about 0.5 seconds to 1.5 seconds. This time will also be affected by factors such as landing posture, ground hardness, exercise intensity, etc. By displacing the counterweight housing 3 relative to the outer shell 6, the unstable time of the photographer during the jump and landing process can be prolonged, which is more conducive to the stability of the shooting. During this time, the counterweight housing 3 moves smoothly without a large acceleration, thereby improving the stability of the shooting. The difficulty of this method of improving shooting stability lies in the processing of the rebound speed after the first compression spring 7 is compressed by the counterweight housing 3. Since the counterweight housing 3 is small in size and light in weight, the traditional hydraulic damping mechanism can solve the problem of repeated vibration of spring rebound. However, when the hydraulic damping mechanism is set in a smaller housing 6, the following problems will be encountered: 1. Damping force is greatly affected by temperature changes. Under different working temperatures, the viscosity of the oil will change, resulting in unstable damping force. For example, under low temperature conditions, the viscosity of the oil increases, and the damping force may increase, while under high temperature conditions, the viscosity of the oil decreases, and the damping force may decrease. 2. After long-term use, the piston, valve and other parts in the damping mechanism are prone to wear, resulting in a decrease in damping force; the gap between the piston and the working cylinder will gradually increase, and the amount of oil leakage will also increase, thereby reducing the damping effect and affecting the shooting due to leakage; 3. Smaller hydraulic damping mechanisms have higher material requirements and higher production costs; 4. The hydraulic damping mechanism requires maintenance, otherwise it is prone to damage; 5. The hydraulic damping mechanism can only provide constant damping. Although the damping can be adjusted, the damping adjusted each time is fixed.

[0029] Taking the jump and landing of the photographer as an example, the working principle of the present invention is explained: No matter the photographer jumps or lands, the counterweight shell 3 will inevitably move downward relative to the outer shell 6. When the counterweight shell 3 moves downward, the counterweight shell 3 will drive the sliding support 4 to move along the sliding rod 5. At the same time, the sliding support 4 on the lower side will also compress the first compression spring 7 with the spring seat 51. As the first compression spring 7 is gradually compressed, the deceleration state of the counterweight shell 3 relative to the outer shell 6 is relatively stable. When the counterweight shell 3 moves downward relative to the outer shell 6 to the maximum stroke, it begins to rebound under the influence of the elastic force of the first compression spring 7. In order to make the counterweight shell 3 in a relatively stable state when it rebounds, for example, the acceleration of the counterweight shell 3 moving upward can be gradually increased, or it can be gradually increased first and then gradually decreased to avoid a more intense collision between the counterweight shell 3 and the buffer pad 12. The specific description is that the acceleration of the counterweight shell 3 moving upward is gradually increased, and this paragraph is explained with the control wheel 9 being a truncated cone. It is clear that when the counterweight housing 3 moves downward, the counterweight housing 3 will drive one end of the inelastic rope 8 to move downward. In order to make one end of the inelastic rope 8 still be able to closely cooperate with the thread groove 901 set on the control wheel 9 during the downward movement, the inelastic rope 8 needs to be tightly attached to the inner side of the thread groove 901. Then, it is necessary to apply tension to the other end of the inelastic rope 8 to prevent any position of the inelastic rope 8 from being loose. Therefore, by fixing the other end of the inelastic rope 8 to the sliding block 1002, the sliding block 1002 is moved by the elastic force of the second compression spring 1003, so as to avoid the situation where the inelastic rope 8 is loose. It should be noted that the elastic force of the second compression spring 1003 is smaller than that of the first compression spring 7. The second compression spring 1003 is only for preventing the inelastic rope 8 from being loose. When the counterweight housing 3 moves downward, the inelastic rope 8 will affect the control wheel 9 and cause it to rotate. The control wheel 9 will move to the right (such as Figure 1 to Figure 2 ), not only that, during this process, the control wheel 9 will rotate and drive the rotating rod 91 to rotate together, and the rotation of the rotating rod 91 will drive the inner ring of the one-way bearing 92 to rotate idly. Therefore, when the counterweight shell 3 moves downward to the maximum stroke relative to the outer shell 6, it begins to rebound under the influence of the elastic force of the first compression spring 7. At this time, the counterweight shell 3 will pull one end of the non-elastic rope 8 to move upward, and the upward movement of one end of the non-elastic rope 8 will cause the control wheel 9 to rotate. The rotation direction of the control wheel 9 at this time is opposite to the rotation direction when the above-mentioned counterweight shell 3 moves downward. At this time, the rotation of the control wheel 9 will move from right to left (as shown in FIG. Figure 2 to Figure 1), during this process, the control wheel 9 will drive the rotating rod 91 to rotate, but the rotating rod 91 at this time cannot drive the inner ring of the one-way bearing 92 to rotate, that is, in this state, the rotating rod 91 can only rotate relative to the inner ring of the one-way bearing 92 by friction, so the rotating rod 91 at this time will have a certain rotation resistance when rotating, and when the non-elastic rope 8 wrapped around the control wheel 9 is close to the upper bottom surface of the control wheel 9 with a smaller diameter, the force point of the non-elastic rope 8 on the control wheel 9 is closer to the axis of the control wheel 9. Therefore, at this time, one end of the non-elastic rope 8 is following the counterweight shell. When the body 3 moves upward, it is more laborious to drive the control wheel 9 through the inelastic rope 8. As the control wheel 9 rotates to move the control wheel 9 to the left, the inelastic rope 8 wound on the control wheel 9 is closer to the lower bottom surface of the control wheel 9 with a larger diameter. At this time, the force point of the inelastic rope 8 on the control wheel 9 is farther away from the axis of the control wheel 9. At this time, it is more labor-saving to drive the control wheel 9 through the inelastic rope 8. Since the rotation resistance of the rotating rod 91 is fixed in this state, as the position of the force point of the inelastic rope 8 on the control wheel 9 changes, the tension applied by the inelastic rope 8 to drive the control wheel 9 also changes. Therefore, the reaction of the inelastic rope 8 and the counterweight shell The tension of the counterweight housing 3 also changes. For example, when the control wheel 9 moves from right to left, the change of the tension of the counterweight housing 3 reacted by one end of the non-elastic rope 8 is gradually reduced. Since the power for the counterweight housing 3 to move upward is provided by the first compression spring 7, it can also be understood that the tension applied by the non-elastic rope 8 to the counterweight housing 3 is a restriction on the upward movement of the counterweight housing 3, so as to prevent the counterweight housing 3 from moving upward too fast and colliding with the buffer pad 12. In addition, the moving time of the counterweight housing 3 in the housing 6 is extended, which can reduce the moving speed of the camera 1 and improve the shooting effect. As the counterweight housing 3 moves upward, the first compression spring As the length of 7 continues to extend, the elastic force applied by the first compression spring 7 to the counterweight housing 3 gradually decreases, and the change in the tension of one end of the non-elastic rope 8 acting on the counterweight housing 3 also gradually decreases. Therefore, the inclination angle of the side of the truncated cone-shaped control wheel 9 (referring to the angle between the generatrix of the side of the truncated cone and the bottom surface of the truncated cone) is one of the important factors for controlling the change in the tension of the non-elastic rope 8 acting on the counterweight housing 3. The inclination angle of the side of the control wheel 9 can be changed according to the weight of the counterweight housing 3 and the change of the use scenario. The use scenario refers to the impact degree caused by the user's exercise intensity, for example, the use scenario is mainly running, jumping or jogging; When the control wheel 9 moves left and right on the rotating rod 91, since the positions of the two ends of the non-elastic rope 8 in the vertical direction are fixed, when the non-elastic rope 8 rotates along the threaded groove 901 of the control wheel 9, the movement of the non-elastic rope 8 can control the left and right movement of the control wheel 9. When the control wheel 9 moves, the limit bar 93 can be set to enable the control wheel 9 to slide relative to the rotating rod 91 and drive the rotating rod 91 to rotate. The steel ball 94 set on the limit bar 93 can reduce the friction between the limit bar 93 and the control wheel 9, so that the control wheel 9 moves more smoothly. In order to further improve the stability of the counterweight shell 3 when it moves upward and avoid a violent collision between the counterweight shell 3 and the buffer pad 12 after the counterweight shell 3 moves upward, the acceleration of the counterweight shell 3 moving upward is gradually increased first and then gradually reduced, so that the counterweight shell 3 can be more gently in contact with the buffer pad 12, and the vibration of the counterweight shell 3 when it stops moving relative to the shell 6 can be reduced. This can be achieved by changing the shape of the control wheel 9, and the control wheel 9 is set to a shape in which the lower bottom surfaces of the two truncated cones overlap, and its working principle is the same as above; After the counterweight shell 3 moves downward to the maximum limit relative to the outer shell 6, it moves upward under the elastic force of the first compression spring 7. The time for the counterweight shell 3 to move upward is adjusted according to the needs of the usage scenario. Then, it is necessary to adjust the rotational resistance of the rotating rod 91 and the inner ring surface of the one-way bearing 92. By rotating the bolt 1107 with a wrench and the set limit ring 1108, the bolt 1107 can be rotated at a certain position of the outer shell 6 without moving. The rotation of the bolt 1107 will drive the sliding shell 1106 to move inside the sliding groove 1105. The sliding groove 1105 cooperates with the outer surface of the sliding shell 1106, and the outer surface of the sliding shell 1106 cannot be circular. The purpose is to prevent the sliding shell 1106 from rotating in the sliding groove 1105. The movement of the sliding shell 1106 will drive the control rod 1103 moves, the movement of the control rod 1103 will drive the push head 1104 to move, the movement of the push head 1104 will squeeze the sliding member 1101 to move, the movement of the sliding member 1101 will drive the friction part 1102 to move, and the contact force between the friction part 1102 and the inner wall surface of the inner ring of the one-way bearing 92 is adjusted by the movement of the friction part 1102, so as to adjust the rotation resistance when the rotating rod 91 rotates relative to the inner ring of the one-way bearing 92. It should be understood that the rotating rod 91 can only drive the inner ring of the one-way bearing 92 to rotate in one direction, that is, the idling state of the one-way bearing 92. When the rotating rod 91 drives the inner ring of the one-way bearing 92 to rotate in the other direction, the inner ring and the outer ring of the one-way bearing 92 are relatively stationary. Therefore, if the rotating rod 91 continues to rotate, it is necessary to overcome the rotation resistance between the rotating rod 91 and the inner ring of the one-way bearing 92. Compared with the traditional hydraulic damping mechanism, the present device is not affected by temperature to cause damping changes, and there will be no oil leakage during long-term use, which greatly reduces the production cost. In addition, there is no involvement of oil, so there is no need for maintenance, and there will be no oil contamination of the entire device. In addition, the inclination angle and shape of the side of the control wheel 9 can be changed according to the weight of the counterweight shell 3 and the changes in the usage scenario, so as to control the moving speed of the counterweight shell 3 during the return movement.
