[0054] Due to the limitations of the shooting environment, the photographer needs to use the remote control system to observe the state of the object being photographed in real time and adjust the focus point position in the viewfinder of the shooting device to achieve precise focus in order to achieve the best shooting effect. However, since some shooting devices do not have the control authority to move the focus point, the remote system cannot use the software to move and adjust the focus point of the shooting device in real time. In addition, since the shooting is done through the remote control system, the photographer cannot move the focus point in real time, making it difficult to achieve precise focus on the object, resulting in the shooting not achieving the best shooting effect.

[0055] The main purpose of the present invention is to provide a focus point moving and adjusting device, which aims to solve the problem that when the existing shooting device is shot through a remote control system, the focus point of the shooting device cannot be remotely controlled to move and adjust the focus point so as to accurately focus on the subject. Figures 1 to 5 FIG. 4 is a schematic diagram of an embodiment of the focus point movement adjustment device.

[0056] See also Figure 1 and Figure 3 The focus point moving adjustment device 100 includes a device shell 1, an adjustment component 2 and an electric drive component 3. The device shell 1 is used to be installed on the shooting device. A mounting cavity a is formed in the device shell 1. One side surface of the device shell 1 is a placement surface. The placement surface is provided with a mounting hole b connected to the mounting cavity a. The adjustment component 2 includes a shift block 21. The shift block 21 has a driving end and a mounting end that are relatively arranged. The mounting end is arranged in the mounting cavity a. The driving end extends from the mounting hole b to protrude outside the device shell 1. The driving end is used to be fixed to the focus point shift lever of the shooting device. The shift block 21 has an active stroke that swings along the aperture direction of the mounting hole b. The electric drive component 3 is arranged in the mounting cavity a to drive the shift block 21 to move.

[0057] In the technical solution provided by the present invention, because the driving end is fixed to the focus point lever of the shooting device, the focus point adjustment lever of the shooting device moves with the shift block 21, and because the shift block 21 has an active stroke of swinging along the aperture direction of the mounting hole b, the shift block 21 is driven to move by the electric drive component 3, so that the focus point adjustment lever has an active stroke of swinging along the aperture direction of the mounting hole b, which solves the problem of moving and adjusting the focus point of the shooting device when the shooting device is shot through a remote control system, so that the shooting device 1000 can accurately focus on the shot object and improve the shooting effect.

[0058] In order to realize that the shift block 21 has a swinging stroke along the aperture direction of the mounting hole b, with the extension direction of the axis of the mounting hole b as the inward and outward direction, the adjustment component 2 also includes an electrically driven mounting seat 22 and a shift block mounting plate 23. The electrically driven mounting seat 22 is arranged on the inner wall of the mounting cavity a. The electrically driven mounting seat 22 is formed with a first mounting surface and a second mounting surface that are relatively arranged. The first mounting surface is used for the placement of the electrically driven component 3. The shift block mounting plate 23 is arranged in the mounting cavity a and is located on one side of the second mounting surface. The shift block mounting plate 23 includes a mounting plate body 231 and a plurality of driving parts 232 protruding from the side of the mounting plate body 231. The driving parts 232 are arranged at intervals along the circumference of the mounting plate body 231, and each of the driving parts 232 has an active stroke in the inward and outward directions, wherein the mounting end of the shift block 21 is arranged on the mounting plate body 231, and is located on the side of the shift block mounting plate 23 away from the electric drive mounting seat 22. In this arrangement, when any of the driving parts 232 moves away from the electric drive mounting seat 22, the active driving part 232 causes the shift block mounting plate 23 to tilt, so that the shift block 21 has an active stroke of swinging along the aperture direction of the mounting hole b, which has a better effect and avoids excessive active stroke of the shift block 21, which causes damage to the focus point shift lever of the shooting device.

[0059] Specifically, in order to drive the shift block mounting plate 23 to move, the electric drive component 3 includes a plurality of motor drive components 31 arranged corresponding to the plurality of drive parts 232, each of the motor drive components 31 includes a drive block 311 movably installed along the inward and outward directions, the drive block 311 is located on the side of the shift block mounting plate 23 close to the electric drive mounting seat 22, the drive block 311 is pressed against the shift block mounting plate 23 to make the shift block mounting plate 23 movable, such a configuration is simple to operate and has good effects.

[0060] Specifically, refer to Figure 4 The driving parts 232 are provided in four numbers, and the corresponding motor driving components 31 are provided in four numbers. Such an arrangement enables the shifting block 21 to swing along the four aperture directions of the mounting hole b, thereby saving costs.

[0061] It should be noted that, in other embodiments, the driving unit 232 can be provided in plurality as needed, so that the shift block 21 can be swung along multiple aperture directions of the mounting hole b, so that the adjustment of the focus point lever of the shooting device is more precise and the adjustment range is wider.

[0062] Further, the driving part 232 is provided with a first avoidance hole 2321, the first mounting surface is provided with a second avoidance hole 221 corresponding to the driving part 232, the driving block 311 is a first driving nut, the motor driving assembly 31 also includes a first driving motor 312 and a first driving screw 313, the first driving motor 312 is arranged on the first mounting surface, the first driving motor 312 has a first output shaft rotatably installed along an axis extending inward and outward, the first output shaft is arranged in the second avoidance hole 221, and the first driving screw 313 is extended inward and outward. One end of the first driving screw 313 is fixedly connected to the first output shaft and rotates coaxially with the first output shaft. The other end of the first driving screw 313 is arranged in the first avoidance hole 2321, and the first driving nut is threadedly sleeved on the first driving screw 313. In this way, when the first output shaft of the first driving motor 312 rotates, the first output shaft drives the first driving screw 313 to rotate, so that the first driving nut moves along the rotation axis direction of the first driving screw 313, pushing the shift block mounting plate 23 to move, which is simple to operate and has good effect.

[0063] Taking into account the reset of the shift block mounting plate 23, specifically, the motor drive assembly 31 also includes a first reset spring 314, and the first reset spring 314 is sleeved on the first drive screw 313, and is located between the shift block mounting plate 23 and the inner wall of the mounting cavity a. In this way, when the first drive nut pushes the shift block mounting plate 23 to move, the shift block 21 moves the focus point lever of the shooting device to complete the focus point movement adjustment, and the first reset spring 314 resets the shift block mounting plate 23 to prepare for the next movement of the focus point lever of the shooting device, which has a better effect.

[0064] Specifically, the aperture of the second avoidance hole 221 is larger than the outer diameter of the first drive nut. Such a configuration allows the first drive nut to move into the second avoidance hole 221, thereby increasing the movement stroke of the first drive nut and having a better effect.

[0065] The first avoidance hole 2321 includes a first hole section 2321a extending along the length direction of the shift block mounting plate 23 and a second hole section 2321b extending along the width direction of the shift block mounting plate 23. The first hole section 2321a is connected to the middle position of the second hole section 2321b. In this way, when the shift block 21 has a swinging stroke along the aperture direction of the mounting hole b, the first hole section 2321a and the second hole section 2321b on the shift block mounting plate 23 provide an avoidance space for the first driving screw 313. In this way, a better effect is achieved.

[0066] The focus point movement adjustment device 100 also includes an elastic sleeve 4, which is sleeved on the shift block 21 and installed in the mounting hole b. This arrangement achieves the support of the shift block 21 and allows the shift block 21 to swing along the aperture direction of the mounting hole b, which has a better effect.

[0067] Reference Figure 3 and Figure 5 The mounting surface is also provided with a mounting hole c connected to the mounting cavity a, and the mounting hole c is located below the mounting hole b. The focus point movement adjustment device 100 also includes an operating component 5, and the operating component 5 includes a pressure column 51 protruding from the mounting hole c and having an inward and outward movable stroke. The pressure column 51 is used to press the focus area selection interface button of the shooting device. In this way, the focus area selection interface button of the shooting device is pressed by the pressure column 51, so as to realize the remote start of the focus area selection interface of the shooting device, and the structure is simple and easy to operate.

[0068] There are many ways to realize that the pressure column 51 presses the focus area selection interface button of the shooting device. Specifically, the extension direction of the axis of the placement hole c is the inward and outward direction; the inner end surface of the pressure column 51 is provided with a give way groove e, and the operating component 5 also includes a second drive motor 52, a second drive screw 53, and a second drive nut 54. The second drive motor 52 is arranged in the installation cavity a, and the second drive motor 52 has a second output shaft extending inward and outward, and the second drive screw 53 is extended inward and outward. One end of the second drive screw 53 is fixedly connected to the second output shaft and rotates coaxially with the second output shaft. The other end of the second drive screw 53 is arranged in the give way groove. In the slot e, the second driving nut 54 is arranged between the second driving motor 52 and the pressure column 51, and is threadedly installed on the second driving screw 53, wherein the second driving screw 53 drives the second driving nut 54 to move inward and outward directions, so that the second driving nut 54 presses against the pressure column 51 to move. In this way, when the second output shaft of the second driving motor 52 rotates, the second output shaft drives the second driving screw 53 to rotate, so that the second driving nut 54 moves along the direction of the rotation axis of the second driving screw 53, pushing the pressure column 51 to move, so that the pressure column 51 presses the focus area selection interface button of the shooting device, which is simple to operate and has good effect.

[0069] Taking into account the resetting of the pressure column 51, specifically, a limiting boss 511 is convexly provided on the outer side surface of the inner end of the pressure column 51, and the operating component 5 also includes a second reset spring 55, which is sleeved on the pressure column 51 and located between the limiting boss 511 and the inner wall of the mounting cavity a. In this way, when the pressure column 51 presses the focus area selection interface button of the shooting device and remotely starts the focus area selection interface of the shooting device, the pressure column 51 is reset by the second reset spring 55, thereby avoiding the problem of damaging the focus area selection interface button of the shooting device due to long-term pressing of the focus area selection interface button of the shooting device, and preparing for the next pressing of the focus area selection interface button of the shooting device, which has a better effect.
