DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] 1-6, the time lapse photography device includes a platform 1, a pan head 2, a support plate 3, and a holder 4. The pan head 2 is rotatably attached to the upper end of the platform 1. A swivel seat is rotatably attached to one side of the pan head 2. One end of the support plate 3 is fixed to the swivel seat. The holder 4 is rotatably attached to the other end of the support plate 3 via a rotating shaft 6. A fixed pulley 5 is provided on the outer periphery of the swivel seat. The fixed pulley 5 is fixed to one side of the pan head 2. One end of the rotating shaft 6 passes through the support plate 3, and a movable pulley 7 is attached to said one end. The fixed pulley 5 is connected to the movable pulley 7 via a belt 10.

[0021] The frame 1 is a triangular frame. The fixed pulley 5 and the movable pulley 7 are both gears or friction pulleys. The fixed pulley 5 is configured to have a hollow structure. The front end of the swivel seat passes through the fixed pulley 5. The fixed pulley 5 is configured to be concentric with the drive rotation axis of the swivel seat.

[0022] A slide groove 8 is provided on the outside of the swivel seat. The two inner side walls of the slide groove 8 are inclined inward, and the opening is tapered. The support plate 3 is plate-shaped, and both sides are formed as inclined surfaces. The inclination angle of the inclined surface of the support plate 3 is the same as the inclination angle of the side wall of the slide groove 8. The support plate 3 is slidably mounted in the slide groove 8. A screw hole is opened on one side of the slide groove 8, and a fastening screw 81 is mounted in the screw hole. The fastening screw 81 is screwed into the screw hole to tighten the support plate 3. The support plate 3 can be adjusted by sliding in the slide groove 8 to adjust the tension of the belt 10. The inclined design of the slide groove 8 is advantageous for locking the support plate 3.

[0023] The number of teeth or diameter of the fixed pulley 5 may be larger than the number of teeth or diameter of the movable pulley 7. The number of teeth or diameter of the fixed pulley 5 may be smaller than the number of teeth or diameter of the movable pulley 7. If the number of teeth or diameter is different, when a vertical rotation of a certain displacement occurs, the dynamic (optical aberration) in which the photograph taken by the mobile phone is tilted at a certain angle can be realized. As shown in the two figures of Figures 1 and 2, when the mobile phone is rotated from left to right, the fixed pulley is fixed to the pan head and does not move, but the movable pulley rotates by the timing belt. Because the number of teeth or diameter is different, a speed difference occurs and the angle of the mobile phone changes (lag or advance). This inevitably changes the photographing angle, resulting in a dynamic tilting optical aberration.

[0024] The number of teeth or the diameter of the fixed pulley 5 may be equal to the number of teeth or the diameter of the movable pulley 7. If the number of teeth or the diameter is the same, there is no tilting effect and the mobile phone can be held in the initial gripping state.

[0025] The holder 4 includes a U-shaped seat 41, a side plate 42, and a clamping base 43. The bottom end of the U-shaped seat 41 is attached to the end of the other end of the rotating shaft 6. One end of the side plate 42 is fixed to the inside of the U-shaped seat 41 via a bolt and a fastening nut so as to be rotatably adjustable. The clamping base 43 is attached to the upper surface of the other end of the side plate 42. A square groove 45 is provided in the center of one side of the bottom end of the U-shaped seat 41. A position limiting block 44 is disposed in the square groove 45 at the end of the side plate 42. The side plate 42 can be rotated and adjusted within the U-shaped seat 41 to change the shooting angle of the mobile phone and meet the shooting needs. The position limiting block 44 and the square groove are configured to prevent the side plate 42 from being over-adjusted.

[0026] The time lapse photography method is a method of photographing using the above-mentioned time lapse photography device.

[0027] First, the smart photography equipment is mounted on the top surface of the holder, and the pan head controls the swivel seat to rotate the swivel seat, which in turn rotates the support plate synchronously. The movable pulley on the support plate forms a transmission cooperative relationship with the fixed pulley on the pan head via a belt or timing belt, and the movable pulley rotates on its own axis and revolves around the fixed pulley. By making the number of teeth or diameter dimensions of the fixed pulley and the movable pulley different, it is possible to make the rotation angle between the smart photography equipment and the pan head different. The lower end of the pan head can rotate at the upper end of the frame in cooperation with the rotation of the swivel seat. The smart photography equipment 9 is one of a mobile phone and a tablet.

[0028] The pan head 2 includes a housing, a built-in power source, a control module, a horizontal rotation drive mechanism, and a vertical rotation drive mechanism. The built-in power source, the control module, the horizontal rotation drive mechanism, and the vertical rotation drive mechanism are disposed in the housing. The pan head 2 may be connected to an external power source. The control module has an electrical connection port located on the upper surface of the housing. The control module, the horizontal rotation drive mechanism, and the vertical rotation drive mechanism are powered by the built-in power source or an external power source. The control module includes a power start switch located on the upper surface of the housing. The horizontal rotation drive mechanism has a lower end drivably connected to the upper surface of the base 1. The vertical rotation drive mechanism has an outer output end connected to the rear end of the swivel seat. The control module can communicate with an external mobile phone or computer via a wireless signal. The mobile phone or computer remotely controls the pan head 2 and rotates the pan head 2 horizontally and / or vertically to drive a mobile phone or other equipment for filming to perform time-lapse filming. The vertical rotation can be achieved by vertically rotating the mobile phone from bottom to top, and by rotating it half a circle from left to right, it can be achieved by left and right displacement. During vertical rotation, if the fixed pulley 5 and the movable pulley 7 have different tooth numbers or diameters, the mobile phone will always tilt at a certain angle when moving from left to right, so that a photo with a tilt effect can be taken. At the same time, the horizontal rotation drives and rotates the entire mobile phone, so the dynamic range of shooting is wider and the displacement is more obvious. During vertical rotation, this device rotates the mobile phone from left to right and then from right to left in the opposite direction, repeating the action, so that the effect of vibration can be realized on the shooting screen. For horizontal rotation, the same reciprocating action is repeated, and by matching it with the above-mentioned left and right reciprocating action, the sense of vibration on the screen is further improved and the shooting range is further expanded.
