Description

Technical Field

[0001] This utility model relates to the field of bracket technology, and in particular to a bracket with an adjustable central axis. Background Technology

[0002] Mobile phones and cameras (or tablets, laptops, etc.) are commonly used devices in people's daily lives and work. In order to meet the shooting needs of some users, a tripod is used to support the shooting equipment during shooting, so as to free up the user's hands.

[0003] In previous applications of tripods, especially in photography, videography, stage lighting setup, and equipment support that requires precise angle positioning, traditional tripods mostly adopted manual adjustment. Taking photography as an example, when photographers are taking group photos or specific scenes, they often need to place the camera on the tripod first, and then manually rotate, stretch, or bend the various joints of the tripod to adjust the angle and height.

[0004] This manual adjustment method has obvious drawbacks. First, the operation process is cumbersome and inefficient. Each time the angle is adjusted, the operator needs to walk to the tripod, manually rotate or push and pull the tripod parts, and then return to the shooting position to check the effect. If not satisfied, the operator needs to return to the tripod to make adjustments again. This process is repeated, which consumes a lot of time and energy. Especially in some time-sensitive shooting tasks, the best shooting opportunity may be missed.

[0005] Secondly, the precision of manual adjustment is difficult to guarantee. Human hand operation has certain limitations in fine adjustments, making it difficult to precisely adjust the tripod to the required angle. This may result in an imperfect composition of the shot, or fail to meet the actual needs of some professional applications that require high angle precision.

[0006] Therefore, we propose a bracket with an adjustable central axis. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies. In situations requiring precise angle positioning, such as photography, videography, and stage lighting setup, traditional supports are mostly manually adjustable. For example, during photography, the photographer must first place the camera on the support and then manually rotate, stretch, or move the support joints to adjust the angle and height. This method has obvious drawbacks: it is cumbersome and inefficient, requiring the operator to travel back and forth between the support and the shooting position for each angle adjustment, which is time-consuming and laborious, and can easily lead to missing the best opportunity in time-sensitive shooting tasks; moreover, the precision of manual adjustment is limited, as the fine manipulation of the human hand is limited, making it difficult to accurately adjust to the required angle, which may result in poor composition of the shot or failure to meet the angle precision requirements of professional applications.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A bracket with an adjustable central axis includes a mounting triangular platform, a first bearing seat is installed inside the mounting triangular platform, a sliding groove is provided on the top of the mounting triangular platform and outside the first bearing seat, and a limit groove is provided at the bottom of the sliding groove.

[0010] A rotation adjustment assembly is installed on the triangular mounting platform. The rotation adjustment assembly includes a rotation motor. The output end of the rotation motor is provided with a rotation shaft. The top of the rotation shaft is provided with a rotation seat. The bottom of the rotation seat is provided with several mounting plates. The bottom of each of the mounting plates is provided with a sliding block.

[0011] A connecting column is installed at the center of the top of the rotating seat. A controller is installed on the side wall of the connecting column. An angle adjustment assembly is provided at the top of the connecting column. The angle adjustment assembly includes an adjustment fixing seat. A servo motor is installed on one side wall of the adjustment fixing seat. A second bearing seat is provided at the connection point of the servo motor.

[0012] As a preferred embodiment of this utility model, the rotating motor can drive the rotating shaft to rotate, the rotating shaft is fixedly connected to the rotating seat, and the rotating shaft is installed at the first bearing seat.

[0013] As a preferred embodiment of this utility model, the mounting plate is fixedly connected to the rotating seat, and the mounting plate and the sliding block are designed as an integral unit. The rotating seat slides in the sliding groove and the limiting groove through the mounting plate and the sliding block, thereby playing an auxiliary supporting role in sliding.

[0014] As a preferred embodiment of this utility model, the controller is electrically connected to the rotary motor and the servo motor, and the controller is also wirelessly connected to an external remote controller.

[0015] As a preferred embodiment of this utility model, an adjustment seat is also installed on the output shaft of the servo motor, a central shaft body is provided at the connection of the adjustment seat, and a camera equipment mounting bracket is provided at the connection of the central shaft body.

[0016] As a preferred embodiment of this utility model, the side wall of the mounting triangular platform is also provided with three base bracket mounting blocks, and the connection points of the three base bracket mounting blocks are all hinged with bottom support frames.

[0017] In a preferred embodiment of this invention, the output shaft of the servo motor is connected to the second bearing housing.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention employs a rotary motor and a servo motor for drive, combined with precise control from a controller. Compared to traditional manual adjustment methods, it achieves more accurate angle adjustments, overcoming the limitations of human hands in fine-tuning operations. This ensures the bracket can precisely reach the required angle, thereby improving the composition quality of the captured image and meeting the stringent requirements for angle accuracy in professional applications such as photography and videography. It provides users with superior visual effects. Furthermore, by adjusting the bracket via remote control and controller, operators no longer need to repeatedly walk to the bracket for manual operation as with traditional brackets, greatly saving time and effort. Especially in time-sensitive shooting tasks, it allows for quick and accurate adjustment of the bracket angle, preventing the loss of optimal shooting opportunities and significantly improving work efficiency.

[0029] Example

[0030] like Figure 1-4 As shown, this utility model provides a technical solution: a triangular platform 1 is installed as the basic component of the entire support, and a first bearing seat 5 is installed inside to provide stable support for the rotation of the rotating shaft 8, reduce frictional resistance, and ensure smoothness and stability of rotation.

[0031] The top sliding groove 6 and the limiting groove 7 cooperate with each other. The sliding groove 6 provides sliding space for the sliding block 11 at the bottom of the rotating seat 9, while the limiting groove 7 restricts and guides the sliding block 11 to prevent it from deviating or detaching during the sliding process, thereby ensuring the smooth movement of the rotating seat 9 in the horizontal direction and further enhancing the stability of the entire support structure.

[0032] The rotating motor 4, as a driving component, has its output shaft 8 fixedly connected to the rotating seat 9 and installed at the first bearing seat 5.

[0033] The function of the rotating motor 4 is to provide power to drive the rotating shaft 8 to rotate, thereby driving the rotating seat 9 to rotate in the horizontal direction. Its principle is to use the electromagnetic induction principle inside the motor to convert electrical energy into mechanical energy. The torque output by the rotation of the motor shaft drives the rotating shaft 8 connected to it to rotate.

[0034] Compared to traditional manual rotation, this driving method offers higher precision and stability, enabling accurate angle control and meeting the needs of applications with high angle requirements.

[0035] The rotating seat 9 is fixedly connected to the mounting plate 10 and the sliding block 11. Several mounting plates 10 at the bottom of the rotating seat 9 are fixedly connected to the rotating seat 9, and the mounting plate 10 and the sliding block 11 are integrated into one piece. This design not only ensures the integrity and stability of the structure, but also enables the rotating seat 9 to slide smoothly in the sliding groove 6 and the limiting groove 7 through the mounting plate 10 and the sliding block 11.

[0036] When the rotating motor 4 drives the rotating shaft 8 to rotate, the rotating seat 9 will rotate accordingly. The sliding block 11 in the sliding groove 6 and the limiting groove 7 plays an auxiliary support and guiding role, making the rotation of the rotating seat 9 more stable, reducing shaking and offset, and improving the reliability and durability of the bracket.

[0037] Adjusting the fixed base 14 and the servo motor 15, the fixed base 14 serves as a support component for the angle adjustment assembly, and the servo motor 15 mounted on one side wall is connected to the adjusting base 17 through the second bearing seat 16.

[0038] The servo motor 15 is a motor that can precisely control angle and speed. Its working principle is based on a closed-loop control system, which continuously adjusts the motor output through feedback signals so that it can rotate precisely according to the preset angle and speed.

[0039] In this bracket, the output shaft of the servo motor 15 is connected to the adjustment seat 17. By controlling the rotation angle of the servo motor 15, the angle of the central axis body 18 can be precisely adjusted to meet different shooting needs.

[0040] The central axis body 18 is connected to the adjusting seat 17, and the camera equipment mounting bracket 19 is provided on its top for mounting the camera equipment. Through the coordinated work of the rotating motor 4 and the servo motor 15, the camera equipment can be precisely adjusted in the horizontal and vertical directions to meet the requirements of shooting angle in various shooting scenarios.

[0041] The controller 13 is mounted on the side wall of the connecting column 12 and is electrically connected to the rotary motor 4 and the servo motor 15. It is also wirelessly connected to the external remote controller.

[0042] Operators can send commands to controller 13 via remote control. After receiving the command, controller 13 will precisely control the operation of rotating motor 4 and servo motor 15, thereby realizing remote adjustment of the bracket angle. This control method is not only convenient and fast, but also enables precise angle control, improving work efficiency and shooting effect.

[0043] The remote control, serving as the command transmitter between the operator and the support, utilizes advanced wireless communication technology, with the 2.4GHz band being widely used due to its strong signal penetration and relatively stable transmission performance.

[0044] When an operator presses a specific button on the remote control, such as a button that represents clockwise rotation by a certain angle, the remote control will convert this operation command into a specific digital signal and transmit it to the surrounding space through the 2.4GHz wireless channel.

[0045] Meanwhile, Bluetooth technology can also be used as an alternative communication method. It has advantages such as low power consumption and easy connection, and can play an excellent role in some scenarios where power consumption is a requirement.

[0046] As an important component of the support system, the controller 13 integrates a high-performance microprocessor and a specially designed drive circuit. The microprocessor has powerful computing capabilities and can quickly capture and analyze the received wireless signals.

[0047] Once a signal is received from the remote control, the microprocessor will immediately start the decoding program and convert it into control instructions that the motor can understand. Taking the rotating motor 4 as an example, if the decoded instruction requires the rotating shaft 8 to rotate 30 degrees clockwise, the microprocessor will accurately calculate the drive pulse sequence and voltage signal required by the rotating motor 4 according to the preset motor control algorithm.

[0048] Next, the microprocessor sends these control signals to the corresponding drive circuit. The drive circuit adjusts the magnitude and direction of the current output to the rotary motor 4 according to the instructions of the microprocessor, thereby driving the motor to rotate. The rotary motor 4, with its precise mechanical structure and efficient electromagnetic conversion principle, quickly responds to changes in the drive current and drives the rotating shaft 8 to rotate precisely in the predetermined direction and angle.

[0049] Throughout the process, thanks to the use of wireless remote control, operators no longer need to frequently travel back and forth between the shooting position and the support as in traditional manual adjustments, thus avoiding the time wasted due to personnel movement.

[0050] Electronic signals travel at near the speed of light in the air, enabling them to send operation commands to the controller 13 almost instantly. The rapid response of the motor also ensures the timeliness of angle adjustment.

[0051] The base bracket mounting block 2 and the bottom support frame 3 are provided on the side wall of the mounting triangular platform 1. Three base bracket mounting blocks 2 are provided, and each base bracket mounting block 2 is hinged to a bottom support frame 3. The bottom support frame 3 can be unfolded or retracted according to the actual use scenario to provide stable support for the bracket.

[0052] When in use, unfold the bottom support frame 3 so that it contacts the ground to form a stable triangular support structure, which can effectively prevent the support from tipping over during use and ensure the safe use of the equipment.

[0053] Working principle:

[0054] When the horizontal angle of the bracket needs to be adjusted, the operator sends a command to the controller 13 via remote control. Upon receiving the command, the controller 13 drives the rotary motor 4 to operate. The output shaft of the rotary motor 4 drives the rotating seat 9 to slide within the sliding groove 6 and the limiting groove 7 on the mounting triangular platform 1, thereby achieving horizontal rotation. Due to the precise control characteristics of the rotary motor 4, precise adjustment of the horizontal angle can be achieved, meeting the requirements for the horizontal angle in different shooting scenarios.

[0055] When the vertical angle of the bracket needs to be adjusted, the operator sends a command to the controller 13 via the remote control. The controller 13 controls the servo motor 15 to operate, and the output shaft of the servo motor 15 drives the adjustment seat 17 to rotate, thereby enabling the vertical angle adjustment of the central axis body 18 and the camera equipment mounting bracket 19. The closed-loop control system of the servo motor 15 can accurately control the rotation angle, ensuring the vertical angle adjustment accuracy and meeting the strict requirements for angle accuracy in professional applications such as photography and videography.

[0056] Workflow:

[0057] For equipment installation, first install the camera equipment on the camera equipment mounting bracket 19 to ensure a firm installation. Then, depending on the actual usage scenario, unfold the bottom support bracket 3 from the base bracket mounting block 2 so that it contacts the ground to form a stable support structure.

[0058] For horizontal angle adjustment, the operator holds a remote control and sends a horizontal angle adjustment command to the controller 13 through the control button on the remote control according to the shooting requirements. After receiving the command, the controller 13 starts the rotating motor 4, which drives the rotating shaft 8 to rotate, causing the rotating seat 9 to slide in the sliding groove 6 and the limiting groove 7, thereby realizing the horizontal angle adjustment of the bracket. During the adjustment process, the operator can observe the viewfinder of the camera equipment and adjust the horizontal angle in real time until a satisfactory shooting angle is achieved.

[0059] Vertical angle adjustment: When the vertical angle needs to be adjusted, the operator sends a vertical angle adjustment command to the controller 13 via the remote control. The controller 13 controls the servo motor 15 to operate, and the output shaft of the servo motor 15 drives the adjustment seat 17 to rotate, thereby realizing the vertical angle adjustment of the central axis body 18 and the camera equipment mounting bracket 19. Similarly, the operator can adjust the vertical angle in real time according to the shooting requirements to ensure that the camera equipment can capture the ideal picture.

[0060] During the shooting process, once the angle adjustment is completed, shooting can begin. If fine adjustments to the bracket angle are needed during shooting, the operator can send instructions to the controller 13 via remote control at any time to adjust the horizontal or vertical angle of the bracket to meet different needs during shooting.

[0061] After the shooting is completed, the camera equipment is first removed from the camera equipment mounting bracket 19 and stored properly. Then, the bottom support bracket 3 is folded up and returned to the base bracket mounting block 2 for easy storage and carrying of the bracket.

[0062] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
