DETAILED DESCRIPTION

[0022] In order to make the purpose and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be clear that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] like Figure 1 As shown, the electric control sliding device 100 of the photographic equipment of the present invention includes a main control component 1, a guide component 2 installed on one side of the main control component 1, a sliding component 3 slidably installed on the guide component 2, and a locking component 4 installed on the guide component 2. The main control component 1 controls the guide component 2 and the sliding component 3. The locking component 4 acts on the guide component 2 to stop the sliding component 3 at any position of the guide component 2. The sliding component 3 includes a support seat 31 and a mounting seat 32 slidably installed on the guide component 2. The mounting seat 32 is used to mount a photographic device (such as a camera, a video camera, etc.). The main control component 1 controls the guide component 2 so that the support seat 31 and the mounting seat 32 move toward or away from each other on the guide component 2, thereby doubling the moving distance of the mounting seat 32. In this embodiment, the support seat 32 can be quickly connected to the bracket of the photographic equipment, thereby connecting the electric control sliding device 100 to the bracket of the photographic equipment.

[0024] The main control assembly 1 includes a housing 11, a main control module 12 installed in the housing 11, and a driving member 13 connected to and controlled by the main control module 12. Preferably, a control panel 14 is arranged on the upper surface of the housing 11, and the control panel 14 is electrically connected to the main control module 12, and a user can control and view the operating status of the electric control sliding device 100 through the control panel 14. In this embodiment, the driving member 13 is configured as a driving gear, which drives the operation of the guide assembly 2 under the control of the main control module 12.

[0025] Also refer to Figure 1 and Figure 2 , the guide assembly 2 includes two guide rails 21, a drive belt 22 and a follower 23. One end of the two guide rails 21 is connected and fixed on the side of the housing 11 of the main control assembly 1. The follower 23 is arranged at one end of the guide rail 21 away from the main control assembly 1, between the two guide rails 21, and opposite to the main control assembly 1. In this embodiment, the follower 23 is arranged as a rotating wheel group, including two identical gears. Optionally, the follower 23 can be configured as a driven gear that is the same as the driving gear of the driving member 13. Preferably, the driving member 13 and the follower 23 are both provided with external teeth, and the drive belt 22 is provided with internal teeth meshing with the external teeth and can move synchronously with the rotation of the driving member 13. The drive belt 22 is supported by the driving member 13 and the follower 23, and is wrapped around the driving member 13 and the follower 23. As a result, the driving member 13, the drive belt 22 and the follower 23 cooperate with each other to realize synchronous belt transmission.

[0026] The support seat 31 and the mounting seat 32 of the sliding assembly 3 can be driven and moved by the driving belt 22 respectively, so that the support seat 31 and the mounting seat 32 can move relative to or away from each other on the guide rail 21 of the guide assembly 2. When the sliding assembly 3 needs to stay at a certain position of the guide rail 21, the user can drive the locking assembly 4 to lock the rotation of the follower 23, so that the sliding assembly 3 stays at the position of the guide rail 21. The locking assembly 4 includes a fixed seat 41 and a locking member 42 movably mounted on the fixed seat 41. The fixed seat 41 is mounted on the end of the guide rail 21 of the guide assembly 2 away from the main control assembly 1. Preferably, the fixed seat 41 is roughly configured as a hollow box body with an opening on one side. The opening 410 of the fixed seat 41 faces the main control assembly. In this embodiment, the follower 23 of the guide assembly 2 is mounted inside the fixed seat 41. The fixed seat 41 is provided with a first through hole 411 and a second through hole 412 opposite to each other. The locking member 42 vertically penetrates the fixing seat 41 via the first through hole 411 and the second through hole 412, and can move and rotate relative to the fixing seat 41. The user stops the rotation of the follower 23 by moving and rotating the locking member 42, thereby stopping the sliding assembly 3 at a desired position.

[0027] Also refer to Figures 3 to 5The locking member 42 includes a body 420, an elastic member 421 abutting between the body 420 and the fixed seat 41, and a locking member 423 sleeved on the body 420. In this embodiment, the body 420 includes a rotating member 201 and a main shaft 202 fixed on the rotating member 201. The elastic member 421 is arranged between the rotating member 201 and the fixed seat 41. Preferably, the elastic member 421 is a spring. The locking member 423 is sleeved on the main shaft 202. The diameter of the rotating member 201 is greater than the diameter of the main shaft 202. The main shaft 202 can move relative to the locking member 423. The rotating member 201 is pressed and rotated by the user, and the main shaft 202 fixed on the rotating member 201 moves and rotates relative to the fixed seat 41 as the rotating member 201 moves and rotates, thereby driving the locking member 201 to engage the driven member 23, and then locking the driven member 23, so that the sliding assembly 3 stays on the guide rail 21.

[0028] In the present embodiment, the spindle 202 passes through the fixing seat 41 via the first through hole 411 and the second through hole 412 of the fixing seat 41. The two ends of the spindle 202 protrude from the two opposite sides of the fixing seat 41 accordingly. One end of the spindle 202 is fixed to the rotating member 201 through a first connecting member 208, and the other end of the spindle 202 is stopped at the corresponding side of the fixing seat 41 through a second connecting member 209 to prevent the locking member from being separated from the fixing seat. In the present embodiment, the first connecting member 208 and the second connecting member 209 are both configured as bolts. The diameter of the second connecting member 209 in the radial direction perpendicular to the axial direction is larger than the diameter of the second through hole 412 of the fixing seat 41 in this direction, thereby blocking the locking member 42 at the second through hole 412 of the fixing seat 41. Optionally, the rotating member 201 and the spindle 202 can be set as one body.

[0029] In this embodiment, the main shaft 202 includes a first non-circular portion 203, a first circular portion 204, a second non-circular portion 205, a second circular portion 206 and a third non-circular portion 207. The first non-circular portion 203, the first circular portion 204, the second non-circular portion 205, the second circular portion 206 and the third non-circular portion 207 are arranged in sequence along the axial direction of the main shaft 202. The first non-circular portion 203 and the third non-circular portion 207 can be respectively locked in the first through hole 411 and the second through hole 412 of the fixing seat 41 to prevent the main shaft 202 from rotating relative to the fixing seat 41. In this embodiment, the shapes of the first through hole 411 and the second through hole 412 match the shapes of the first non-circular portion 203 and the third non-circular portion 207 respectively. The locking member 423 is at least partially sleeved at the second non-circular portion 205. The second non-circular portion 205 can drive the locking member 423 to rotate, so that the locking member 423 is engaged at the driven member 23. In this embodiment, the transverse cross-sections of the first non-circular portion 203, the second non-circular portion 205, and the third non-circular portion 207 are all hexagonal. The first circular portion 204 and the second circular portion 206 can be located in the first through hole 411 and the second through hole 412, respectively, and when the first circular portion 204 and the second circular portion 206 are located in the first through hole 411 and the second through hole 412, respectively, the main shaft 202 is allowed to rotate relative to the fixing seat 41.

[0030] Specifically, the rotating member 201 is pressed downward toward the fixed seat 41 to drive the main shaft 202 to move along the axial direction of the main shaft 202. At this time, the elastic member 421 is compressed, and the first circular portion 204 and the second circular portion 206 are respectively located at the first through hole 411 and the second through hole 412, and the second non-circular portion 205 is engaged in the locking member 423. Then, the rotating member 201 is rotated in the first direction to drive the main shaft 202 to rotate, and the locking member 423 is engaged at the follower 23 under the action of the second non-circular portion 205. Then, the rotating member 201 drives the main shaft 202 to move upward under the action of the elastic member 421. At this time, the first non-circular portion 203 and the third non-circular portion 207 are respectively located at the first through hole 411 and the second through hole 412, and the second non-circular portion 205 is at least partially engaged in the locking member 423, preventing the locking member 423 from moving, thereby locking the follower 23 to stop the sliding assembly 3 on the guide rail 21.

[0031] To release the lock of the follower 23 by the locking member 423, the rotating member 201 is pressed toward the fixed seat 41, and then the rotating member 201 is rotated in the second direction, so that the second non-circular portion 205 of the main shaft 202 drives the locking member 423 to rotate to release the engagement between the locking member 423 and the follower 23, and then the pressure on the rotating member 201 is released. The rotating member 201 drives the main shaft 202 to move upward under the action of the elastic member 421. At this time, the first non-circular portion 203 and the second non-circular portion 205 are respectively located at the first through hole 411 and the second through hole 412, and the second non-circular portion 205 is at least partially engaged in the locking member 423, preventing the locking member 423 from moving, thereby preventing the locking member 423 from affecting the rotation of the follower 23.

[0032] In this embodiment, the locking member 423 includes a connecting portion 231 and at least one engaging portion 232 extending radially outward from the connecting portion 231. The connecting portion 231 is roughly in the shape of a hollow column. The center of the connecting portion 231 is set as a connecting hole 233, and the second non-circular portion 205 is at least partially engaged in the connecting hole 233, that is, the shape of the connecting hole 233 is roughly the same as the shape of the second non-circular portion 205. The second non-circular portion 205 can move in the connecting hole 233 along the axial direction of the main shaft 202, and does not disengage from the connecting hole 233 during the movement. In this embodiment, the at least one engaging portion 232 includes two engaging portions extending in opposite directions. Preferably, the size of the engaging portion 232 is set to be able to engage in the teeth of the driven member 23. In this embodiment, in order to prevent the locking member 423 from moving along the axial direction of the main shaft 202, a first sleeve 426 is arranged between the side of the fixing seat 41 having the first through hole 411 and the locking member 423. The first sleeve 426 is disposed on the main shaft 202, and both ends of the first sleeve 426 respectively abut against the fixing seat 41 and the locking member 423. It is conceivable that the main shaft 202 can move and rotate relative to the first sleeve 426. Optionally, a second sleeve 427 is arranged between the side of the fixing seat 41 having the second through hole 412 and the locking member 423.

[0033] In addition, the locking member 42 further includes a stopper 424 adjacent to the rotating member 201 of the body 420. The rotating member 201 and the stopper 424 enclose a receiving space for receiving the elastic member 421, so that the elastic member 421 abuts between the stopper 424 and the rotating member 201 of the body 420. The stopper 424 includes a hollow main body 240 with an open end and a protrusion 242 extending axially outward from the closed end 241 of the main body 240. The main body 240 provides a part of the above-mentioned receiving space. Preferably, the rotating member 201 is sleeved on the outer side of the stopper 424 and can move relative to the stopper 424 along the axial direction of the rotating member 201. In this embodiment, the first non-circular portion 203 of the main shaft 202 of the body 420 passes through the third through hole 243 at the center of the closed end 241 of the main body 240, so that the stopper 424 rotates with the rotation of the rotating member 201. The design of the stopper 424 improves the aesthetics of the device and makes the rotation of the entire locking member 42 smoother. The protrusion 242 is used to limit the rotation angle of the rotating member 201. The fixing seat 41 of the locking assembly 4 is provided with an annular hole 413 at a position corresponding to the protrusion 242 of the stopper 424. The protrusion 242 is inserted into the annular hole 413.

[0034] In this embodiment, the center of the axial outer side of the closed end 241 of the stopper 424 is recessed to form a recess 244, and the fixing seat 41 is provided with a boss 245 at a corresponding position, and the boss 245 is engaged in the recess 244. The arrangement of the recess 244 and the boss 245, which are matched with each other, prevents the stopper 424 from being offset relative to the fixing seat 41.

[0035] The above descriptions are merely preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. That is, any equivalent changes and modifications made according to the contents of the present invention should fall within the technical scope of the present invention.
