[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] A small visual pan-tilt system, such as Figure 1 As shown, a small vision gimbal system is provided. The system is provided with a base 2 and a housing 1, with the housing 1 covering the base 2. An elliptical groove is provided on the housing 1. A support plate 9 is provided at one end of the base 2, and a gimbal bracket 7 is hinged to the support plate 9. A vision camera 8 is provided at the other end of the gimbal bracket 7, and the vision camera 8 extends out of the elliptical groove. A motor 4 is provided at one end of the base 2. The output end of the motor 4 is connected to a linkage mechanism, and the other end of the linkage mechanism is connected to the gimbal bracket 7.
[0029] In this way, when it is necessary to adjust the angle of the vision camera 8, the motor 4 drives the linkage mechanism, which in turn drives the linkage mechanism 7 to rotate around the connection point with the housing 1, thereby causing the vision camera 8 to slide along the elliptical groove, thus changing the angle of the vision camera 8 and effectively adjusting the camera angle. Moreover, the device has a simple structure and is easy to maintain, effectively overcoming the defects of traditional rigid transmission mechanisms (such as gears and slide rails) such as large inertia and high delay. It also makes the device structure compact, significantly saving internal space of the housing and making the overall system size smaller, especially suitable for small vision camera devices.
[0030] In embodiments of this utility model, such as Figure 1 and Figure 6 As shown, the linkage mechanism includes a motor crank 5 and a support link 6. The motor crank 5 is connected to the output end of the motor 4. One end of the support link 6 is hinged to the motor crank 5, and the other end of the support link 6 is hinged to the gimbal bracket 7. Thus, starting the motor 4 drives the motor crank 5 to rotate, which in turn drives the support link 6 to reciprocate. The other end of the support link 6 is hinged to the gimbal bracket 7, which in turn drives the gimbal bracket 7 to rotate around the connection point with the housing 1. As a result, the gimbal bracket 7 drives the vision camera 8 to move within the elliptical groove of the housing 1, changing the angle of the vision camera 8.
[0031] In embodiments of this utility model, such as Figure 4As shown, the base 2 is L-shaped. In this way, the base 2 is designed in an L-shape. On the one hand, its right-angle bending structure forms a stable mechanical support frame, which can evenly distribute the load of the gimbal bracket 7. On the other hand, the structure is compact, which significantly saves the internal space of the housing 1 and makes the overall system smaller, especially suitable for the integration requirements of the small vision camera 8. At the same time, the support plate 9 is set as a support plate with an inclination angle of 53°.
[0032] In embodiments of this utility model, such as Figure 4 The base 2 shown is provided with a motor support frame 3, and an arc-shaped groove is provided on the motor support frame 3. The motor 4 can be placed in the arc-shaped groove. In this way, the motor support frame 3 is also set on the base 2, which makes the structure compact, significantly saves the internal space of the housing 1, and makes the overall system smaller, especially suitable for the integration requirements of small vision camera 8.
[0033] In embodiments of this utility model, such as Figure 7 As shown, the gimbal bracket 7 is T-shaped, so that the vision camera 8 is set on the side with a larger contact surface of the gimbal bracket 7, making it more secure.
[0034] In embodiments of this utility model, such as Figure 1 As shown, the housing 1 is olive-shaped. After the base 2, motor 4, gimbal bracket 7 and vision camera 8 are installed, the elliptical groove of the housing 1 is aligned with the vision camera 8, and then the housing 1 is inserted into the device.
[0035] Implementation Process: In use, the base 2 and motor support frame 3 are installed onto the required equipment using bolts. Then, the motor 4 is installed onto the motor support frame 3, and the pan-tilt bracket 7 is installed onto the 53° support plate 9 of the base 2. The support connecting rod 6 is connected to the pan-tilt bracket 7, and then the support connecting rod 6 is connected to the motor crank 5. The motor 4 and motor crank 5 are then installed to rotate. The vision camera 8 is then fixed onto the pan-tilt bracket 7. Finally, the body 1 is inserted into the equipment to complete the assembly. The motor 4 is then started to drive the motor crank 5 to rotate, which in turn drives the support connecting rod 6 to swing back and forth. The other end of the support connecting rod 6 is hinged to the pan-tilt bracket 7, which in turn drives the pan-tilt bracket 7 to rotate around the connection point with the housing 1. Thus, the pan-tilt bracket 7 drives the vision camera 8 to move within the elliptical groove of the housing 1, changing the angle of the vision camera 8. The equipment has a simple structure and is easy to maintain. It effectively overcomes the defects of traditional rigid transmission mechanisms, such as large inertia and high delay. It also makes the equipment structure compact, significantly saving internal space of the housing and making the overall system smaller, especially suitable for small vision camera equipment.
[0036] It should be noted that the specific model specifications of motor 4 and vision camera 8 need to be selected and determined according to the actual specifications of the device, so they will not be described in detail here.
[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
