Fig. 4 is a partial enlarged view at a of fig. 3. Fig. 8 is a partial enlarged view at B of fig. 4.
Referring to fig. 4 and 8, in an embodiment, the telescopic mechanism 32 is configured to implement telescopic movement of the camera mechanism 31 by using electric force, and the telescopic mechanism 32 includes a driving motor 321, a screw 322, two guide shafts 323, and a motor base 324.
The driving motor 321 is mounted on the motor base 324, and is mounted on the riser 232 of the bracket 23 through the motor base 324. Specifically, the motor base 324 is a fixing frame, one end of the fixing frame is connected with the vertical plate 232, the other end of the fixing frame is connected with the driving motor 321, and an output shaft of the driving motor 321 penetrates through the motor base 324.
One end of the screw rod 322 is rotatably connected with the cross beam 231 of the bracket 23, and the other end is driven to rotate by the driving motor 321. Specifically, in the structure shown in fig. 8, the output shaft of the driving motor 321 is provided with a gear transmission mechanism (not shown), one end of which is connected to the output shaft of the driving motor 321, and the other end of which is connected to one end of the screw 322. The driving motor 321 drives the screw rod 322 to rotate through the gear transmission of the gear transmission mechanism.
Alternatively, referring to fig. 9, fig. 9 illustrates the structure of a telescoping mechanism 32 of another embodiment. The driving motor 321 is a stepping motor or a servo motor. An output shaft of the driving motor 321 is connected to one end of the screw rod 322 through a coupling (not shown), and the driving motor 321 drives the screw rod 322 to rotate through transmission of the coupling, so that the screw rod 322 rotates along with rotation of the output shaft of the driving motor 321.
The guide shafts 323 are provided in two. One end of the guide shaft 323 is mounted on the cross beam 231, and the other end is mounted on a fixing seat 2321 protruding outwards from the riser 232. Two guide shafts 323 are arranged in parallel with the screw 322. Two guide shafts 323 are respectively arranged at two sides of the through hole 2311, and one guide shaft 323 is positioned between the through hole 2311 and the strip-shaped hole 2312.
One end of the guide shaft 323 near the fixed seat 2321 is set as a first position 4, and one end of the guide shaft 323 near the cross beam 231 is set as a second position 5. Referring to fig. 4 and 5, the shaft hole 3114 of the base 311 is disposed through the guide shaft 323, and the screw rod 322 is screwed into the threaded hole 3115 of the base 311. The output end of the driving motor 321 rotates and drives the screw rod 322 to rotate, and the base 311 moves linearly along the guide shaft 323 under the guiding action of the guide shaft 323, so as to drive the image pickup platform 312 to protrude from the cross beam 231 of the bracket 23 through the through hole 2311.
The telescopic mechanism 32 drives the base 311 to move between the first position 4 and the second position 5, so that the imaging platform 312 is telescopic relative to the cross beam 231 of the stand 23. The direction of the connection line between the first position 4 and the second position 5 is approximately parallel to the lead screw 322 of the guide shaft 323.
In addition, the imaging platform 312 corresponds to the through hole 2311 of the cross member 231, and the guide shaft 323 on the left side with respect to the through hole 2311 is located between the through hole 2311 and the bar-shaped hole 2312, so that the distance between the base 311 and the bar-shaped hole 2312 is smaller than the distance between the imaging platform 312 and the bar-shaped hole 2312 when the base 311 and the imaging platform 312 are respectively opposite to the bar-shaped hole 2312, and thus the length of the base 311 is longer than the length of the imaging platform 312.
The main operation flow of the telescopic mechanism 32 is as follows: the output end of the driving motor 321 rotates and drives the screw rod 322 to rotate, and the base 311 moves linearly along the guide shaft 323 under the guiding action of the guide shaft 323, so as to drive the image pickup platform 312 to protrude from the cross beam 231 of the bracket 23 through the through hole 2311.
When the base 311 is at the first position 4, the imaging platform 312 is accommodated in the rear housing 22, and the imaging platform 312 is flush with the side of the housing 2 corresponding to the through hole 2311. If the base 311 is at the second position 5, the camera platform 312 protrudes outside the rear housing 22, and the camera 3122 of the camera platform 312 shoots outwards.
The telescopic mechanism 32 drives the base 311 to move between the first position 4 and the second position 5, so that the image pickup platform 312 stretches and contracts relative to the rear shell 22 of the shell 2, and the image pickup platform 312 is hidden in the rear shell 22 of the shell 2 when not in use and automatically stretches out when in use. When the image capturing platform 312 is accommodated in the rear shell 22, the image capturing platform 312 is protected by the outer layer of the shell 2, so that the outer surface of the camera 3122 of the image capturing platform 312 is prevented from being damaged, further, the shooting effect of the camera 3122 is ensured, and meanwhile, a notch corresponding to the camera 3122 does not need to be formed on the front side of the middle frame 21 of the digital television 100, so that the overall attractiveness of the digital television 100 is not affected.
Fig. 4 is a partial enlarged view at a of fig. 3. Fig. 10 is a partial enlarged view at C of fig. 4.
Referring to fig. 4 and 10, the locking mechanism 33 includes a locking switch 331 and a switch slide 332. The locking switch 331 is fixedly arranged on the inner wall of the rear shell 22 of the shell 2, and is electrically connected with a power supply (not shown) of the telescopic mechanism 32, and meanwhile, the locking switch 331 is controlled by the switch sliding key 332.
The switch sliding key 332 is adapted to the bar-shaped hole 2312 and slides along the length direction of the bar-shaped hole 2312 to adjust the on state and the off state of the locking switch 331.
