Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The utility model aims to provide a tripod head mechanism which is used for eliminating the influence of a return clearance on the position precision of the tripod head mechanism.
In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. The fixed connection in this embodiment may be a direct fixed connection (direct contact) or an indirect fixed connection (non-contact). The fixed connection mode can be a detachable fixed connection mode such as fixing by a fastener, or an undetachable fixed connection mode such as welding, bonding and the like. In the drawings of this embodiment, the first driving device is used for adjusting the horizontal angle of the photographing apparatus, and the second driving device is used for adjusting the pitch angle of the photographing apparatus.
Referring to fig. 1 to 11, the present embodiment provides a pan-tilt mechanism, which includes a base 1, a first driving device, a control system, and a first damping structure.
Wherein the first drive means comprises a first motor 6, a first output gear and a carrier. The first motor 6 is fixed on the base 1, and the first motor 6 is in transmission connection with the first output gear to drive the first output gear to rotate. The first output gear is rotatably mounted on the base 1. The bracket is fixed on the first output gear and is used for installing the shooting equipment 4. The photographing apparatus 4 may output photographing data through the video cable 23, or may output photographing data through wireless transmission. As a possible example, in this embodiment, the first output gear is a sector gear, and the bracket is a U-shaped bracket, and the opening of the U-shaped bracket faces to the side away from the base 1. Since the carrier is fixed as one piece with the first output gear, the whole is shown in the figure as a U-shaped carrier 2 with a sector gear. Other forms of first output gear and carrier, such as a circular gear for the first output gear and a square frame for the carrier, may be selected by those skilled in the art depending on the actual needs.
The control system comprises a first encoder assembly and a controller, the first encoder assembly is electrically connected with the controller, and the controller is electrically connected with the first motor 6. The first encoder assembly is used to monitor the actual angle of the first output gear and transmit it to a controller which is used to control the action of the first motor 6.
The first damping structure is used for providing friction force for preventing the rotation of the first output gear, so that the position of the first output gear is unchanged when the first motor 6 stops working.
The working principle of the cradle head mechanism is as follows:
in this embodiment, the control system does not monitor the angle of the output shaft of the first motor 6 (the initial end of the drive chain of the first drive device), but rather the angle of the first output gear (the end of the drive chain of the first drive device), and is therefore not affected by the return clearance of the first drive device. When the first output gear rotates to the designated position, the first motor 6 stops working, and the first output gear stops rotating under the action of friction force and keeps the position unchanged. Because the rotation speed of the first output gear is low and the friction force is large, the inertia sliding distance is approximately zero. Therefore, the pan-tilt mechanism of the present embodiment can improve the positional accuracy of the first output gear, and further improve the positional accuracy of the photographing apparatus 4 indirectly mounted on the first output gear.
As a possible example, in the present embodiment, the first damping structure includes the damping member 20, and the damping member 20 is in contact with both the base 1 and the first output gear. The damping member 20 may be made of rubber or other materials such as silica gel, and those skilled in the art can select a material having a corresponding friction coefficient according to the actual friction coefficient.
As a possible example, in the present embodiment, a receiving groove for inserting the damper 20 is formed between the first output gear and the base 1 to limit the position of the damper 20.
As a possible example, in this embodiment, the damping member 20 is annular, the accommodating groove is correspondingly annular, and the damping member 20 and the accommodating groove are coaxial with the first output gear. Other shapes of the damping member 20 may be selected by those skilled in the art as desired. For example, the damping member 20 includes a plurality of square-shaped damping members distributed in a circumferential array about the axis of the first output gear, and the base 1 is provided with a receiving groove corresponding to the square-shaped damping member.
As a possible example, in this embodiment, the first damping structure further includes a locking member for applying a locking force for bringing the first output gear and the base 1 close to each other so that the first output gear and the base 1 press the damping member 20 to maintain a certain friction force. The types of locking members are various and can be selected by those skilled in the art according to actual needs. For example, the locking member may include a bolt, a nut and a spring, the nut is located at a side of the first output gear away from the base 1, a screw portion of the bolt sequentially penetrates through the base 1 and the first output gear, the screw portion of the bolt is in threaded connection with the nut, a screw portion of the bolt is located at a side of the base 1 away from the first output gear, the spring is sleeved on the outer side of the screw portion of the bolt, two ends of the spring respectively abut against the screw portion of the bolt and the base 1, and the spring is compressed. In this way, a locking force can be provided by the spring, causing the first output gear to press the damping member 20 with the base 1.
As a possible example, in this embodiment, the lock member is fixedly connected to the first output gear so that the lock member rotates in synchronization with the first output gear. The first encoder assembly includes a first magnetic encoder 11 and a first magnet 10, the first magnet 10 being fixedly coupled to the locking member such that the first magnet 10 rotates in synchronization with the first output gear. The first magnetic encoder 11 is fixed on the base 1, and the first magnetic encoder 11 is used for sensing the angle of the first magnet 10 and transmitting the angle information to the controller. The first output gear, the first magnet 10 and the first magnetic encoder 11 are coaxial. Other types of commonly used encoder assemblies, such as photoelectric encoder assemblies, etc., may also be selected by those skilled in the art, depending on the actual needs.
As a possible example, in this embodiment, the locking member includes a mounting seat 19 and a countersunk head pin 24. The mounting seat 19 is in sliding contact with one side of the base 1 remote from the first output gear. The nail body of the countersunk head nail 24 passes through the mounting seat 19 and is fixedly connected with the first output gear, and the nail head of the countersunk head nail 24 abuts against the mounting seat 19 so as to fixedly connect the first output gear with the mounting seat 19. The first magnet 10 is fixed to the mount 19. The mounting seat 19, the countersunk head nail 24 and the first magnet 10 are coaxial.
As a possible example, in the present embodiment, the mounting base 19 is provided with a mounting groove for mounting the first magnet 10, and the first magnet 10 is fixed in the mounting groove. The surface of the mounting seat 19 facing the first output gear is provided with a groove, the surface of the first output gear facing the mounting seat 19 is provided with a bulge, the bulge is in plug-in fit with the groove, and the bulge and the groove are coaxial with the first output gear.
As a possible example, in this embodiment, the pan-tilt mechanism further includes a second driving device including the second motor 12 and the second output gear 18. The second motor 12 is fixed on the bracket, and the second motor 12 is in transmission connection with the second output gear 18 to drive the second output gear 18 to rotate. The axis of the second output gear 18 is perpendicular to the axis of the first output gear. In use, the axis of the first output gear is typically set vertically and the axis of the second output gear 18 is set horizontally. Other angles may be selected by those skilled in the art depending on the actual needs.
The second output gear 18 is fixedly connected to the photographing apparatus 4 to drive the photographing apparatus 4 to rotate. The stand is adapted to be rotatably connected to the photographing apparatus 4 to support the photographing apparatus 4. Specifically, in this embodiment, the photographing apparatus 4 is fixed in the fixing base 3, and the fixing base 3 is rotationally connected with the bracket, so as to achieve indirect rotational connection between the bracket and the photographing apparatus 4. It will be appreciated that the axis of rotation of the bracket in rotational connection with the photographing apparatus 4 should be collinear with the axis of the second output gear 18.
The control system includes a second encoder assembly electrically connected to a controller electrically connected to the second motor 12. The second encoder assembly is used to monitor the actual angle of the second output gear 18 and transmit it to a controller, which is used to control the action of the second motor 12. The control system does not monitor the angle of the output shaft of the second motor 12 (the initial end of the drive chain of the second drive) but rather the angle of the second output gear 18 (the end of the drive chain of the second drive) and is therefore not affected by the return clearance of the second drive.
According to the embodiment, the first driving device and the second driving device are arranged at the same time, so that the tripod head mechanism can better adjust the angle of the shooting equipment 4.
As a possible example, in this embodiment, the pan-tilt mechanism further includes a second damping structure for providing a friction force that resists the rotation of the second output gear 18, so that the position of the second output gear 18 is unchanged when the second motor 12 stops operating. When the second output gear 18 rotates to the designated position, the second motor 12 stops operating, and the second output gear 18 stops rotating under the action of friction force and keeps the position unchanged.
As a possible example, in the present embodiment, the second damping structure is an interference fit structure between the second output gear 18 and the bracket. Other forms of the second damping structure may be selected by those skilled in the art depending on the actual needs. For example, a damping rubber ring is provided between the contact surface (rotational contact position) of the second output gear 18 and the bracket.
As a possible example, in this embodiment, the second encoder assembly includes a second magnetic encoder 17 and a second magnet 16, where the second magnet 16 is fixedly connected to a second output gear 18, the second magnetic encoder 17 is fixed on a support, and the second magnetic encoder 17 is used to sense an angle of the second magnet 16. The second output gear 18, the second magnet 16 and the second magnetic encoder 17 are coaxial.

As a possible example, in the present embodiment, the controller includes a motor drive PCB21 (PCB finger printed circuit board) fixed to the base 1. The first encoder assembly is electrically connected to the motor drive PCB21, and the motor drive PCB21 is electrically connected to the first motor 6.

A pitch detection PCB22 is fixed on the bracket, the second encoder assembly is electrically connected with the pitch detection PCB22, the pitch detection PCB22 is electrically connected with a motor drive PCB21, and the motor drive PCB21 is electrically connected with the second motor 12.

As a possible example, in this embodiment, the first magnet 10 and the second magnet 16 are neodymium-iron-boron magnets. Other types of magnets may be selected by those skilled in the art as desired.

Other types of first and second drive arrangements may be selected by those skilled in the art as long as the first and second output gears 18 are driven in rotation, depending on the actual needs. In this embodiment, the first driving device and the second driving device both use worm gear speed reducing mechanisms, and those skilled in the art may select other types of speed reducing mechanisms or speed reducing motors with speed reducing mechanisms. To reduce the size of the pan-tilt mechanism, the first motor 6 and the second motor 12 may be miniature permanent magnet stepper motors.
In order to reduce the weight and the cost, the transmission members other than the motor in the first driving device and the second driving device are usually made of plastic materials. The plastic worm gear is difficult to process, the manufacturing cost is relatively high, the plastic helical gear is easy to process, and the manufacturing cost is relatively low.
