The embodiment of the application provides a display device, which can be a flat-panel television, a computer monitor, a monitoring display or a computer all-in-one machine and also can be a laser television. The display device includes a display panel 1 and a housing 2 as shown in fig. 1. The imaging side of the display panel 1 is defined as the front side, that is, the other side of the display panel 1 opposite to the imaging side is the rear side of the display device. When the display panel 1 is mounted, for example, the housing 2 may include a bezel 21, a main housing 22 and a rear cover 23, the bezel 21 and the main housing 22 are respectively located at the front and rear sides of the display panel 1, and the bezel 21 may be fixedly connected to the main housing 22, so as to complete the fixed mounting of the display panel 1 to protect the edge of the display panel 1. Thus, a mounting space (not shown) may be formed between the rear side of the display panel 1 and the main case 22, and a circuit board or a support structure for accommodating the display device may be mounted in the mounting space. Wherein the rear side of the main housing 22 is provided with an opening (not shown) corresponding to the rear cover 23 so that the installation space can be opened or closed by detaching or attaching the rear cover 23.

It should be noted that the rear cover plate 23 and the main housing 22 may be a split structure as shown in fig. 1, or may be an integrated structure, which is not limited in the present application. If the Display device is a flat panel television, a computer monitor, a monitor Display or a computer-integrated device, the Display panel 1 may be a Liquid Crystal Display (LCD) panel or an Organic Light-Emitting Display (OLED) panel. In addition, if the display device is a laser television, the display panel 1 may be a screen or a fresnel panel, and the image side of the corresponding screen or fresnel panel faces the projector.

In the embodiments of the present application, unless otherwise specified, the description will be given taking a display device as a flat panel as an example. As shown in fig. 2, the housing 2 of the flat tv may further include two bracket bases 24, and the two bracket bases 24 are respectively connected to the lower side edge of the main casing 22 and are spaced apart from each other in the left-right direction. In this way, the flat tv with the stand base 24 can be placed on a tv cabinet or other supporting table to carry the flat tv through the stand base 24. In addition, the rear cover plate 23 and the tv wall may be connected by a wall-mounted bracket (not shown) to mount the flat tv on the tv wall.

With the development of science and technology and the improvement of living standard, the current flat panel televisions are developing towards intellectualization, digitalization and networking, and as the application of the functions of television video telephony, television chat and the like is wider and wider, a camera with an image acquisition function becomes an indispensable structural component of the flat panel televisions.

In order to make the flat tv more beautiful, the camera is generally installed in the installation space in a retractable manner. Thus, when the camera is used, the camera can extend out from the camera opening 25 (as shown in fig. 2) on the upper side of the main shell plate 22, and when the camera is not needed, the camera can retract into the installation space from the camera opening 25 to be hidden and stored. However, due to the requirement of the shooting angle, the camera needs to be rotated to the left or to the right when in the extended state, so as to improve the acquisition range of the image information by the camera.

The problem that a camera of a flat-panel television cannot rotate in an extending state is solved. As shown in fig. 3, fig. 3 is a camera lifting and turning device 10 of the related art. The camera lifting and turning device 10 comprises a mounting frame 01, a driving assembly 02, a camera 03 and a housing 04. Wherein, drive assembly 02 can include lift driving motor 021, lead screw 022, lift slider 023 and lifter 024. Lift driving motor 021 installs in the below of mounting bracket 01, and lead screw 022 rotatably connects on mounting bracket 01, and the lower extreme of lead screw 022 passes through the shaft coupling transmission with lift driving motor 021's output and is connected to make lift driving motor 021 can drive the synchronous rotation of lead screw 022. Be equipped with mounting hole and internal thread hole on lifting slide 023, the lower extreme of lifter 024 is installed in lifting slide 023's mounting hole, and lead screw 022 passes lifting slide 023's internal thread hole to in internal thread hole transmission cooperation, mounting bracket 01 is passed to the upper end of lifter 024 and is connected with camera 03.

Thus, from top to bottom, the screw rod 022 can be synchronously driven to rotate clockwise or counterclockwise by controlling the rotation of the lifting drive motor 021. When the lead screw 022 rotates clockwise, the lead screw 022 can lift the lifting slider 023 through the internal thread hole, so that the lifting slider 023 can drive the lifting rod 024 and the camera 03 to lift upwards. When the lead screw 022 anticlockwise rotates, the lead screw 022 can control the lifting slide 023 to descend through the internal thread hole, so that the lifting slide 023 can drive the lifting rod 024 and the camera 03 to retract downwards.

To control the camera 03 to turn left or right, reference is continued to fig. 3. Drive assembly 02 may also include a guide rod 025, a rotary motor 026, a drive gear 027, and an impulse gear 028. Wherein, rotating motor 026 is fixed mounting in the below of mounting bracket 01, and is located the left side of lift driving motor 021. On lifting slide 023, a guide hole is further formed in the left side of the inner threaded hole, the lower end of guide rod 025 sequentially penetrates through the guide hole and mounting frame 01 and is in transmission connection with an output shaft of rotating motor 026 through a coupler, and the upper end of guide rod 025 penetrates through support frame 01 and is in transmission connection with driving gear 027. Below camera 03, lifter 024 corresponds and is connected with driven gear 028 transmission, and driving gear 027 and driven gear 028 intermeshing. Because the lower end of the lifting rod 024 is rotatably connected with the lifting slide 023, and the lifting slide 023 can limit the relative movement of the lifting rod 024 and the lifting slide 023 in the vertical direction. Since the lifting rod 024 and the driven gear 028 can slide in the vertical direction, the housing 04 can be covered under the camera 03, and the housing 04 is connected with the mounting rack 01, so that the driven gear 028 is prevented from moving upwards along with the lifting rod 024.

In summary, from top to bottom, by controlling the rotation of the rotating motor 026, the driving gear 027 can be driven to rotate clockwise or counterclockwise by the guiding rod 025. When the driving gear 027 rotates clockwise, the driven gear 028 engaged with the driving gear 027 rotates counterclockwise, that is, the driven gear 028 can drive the camera 03 to rotate counterclockwise through the lifting rod 024. Similarly, when the driving gear 027 rotates counterclockwise, the camera 03 can be driven to rotate clockwise. Since the driving gear 027 and the driven gear 028 are always in a meshed state, the camera can be controlled to rotate left or right by controlling the rotating motor regardless of whether the camera is in an extended state or a retracted state without an obstacle.

However, in the above embodiment, the moving process of the camera 03 in the up-down direction and the rotating process of the camera 03 are two completely independent motion processes, and are respectively driven and controlled by two motors. That is, the structure of the camera lifting and turning device 10 is complex due to the double motor modules, which is not beneficial to reducing the volume and production cost of the device.

In order to solve the above problem, referring to fig. 2 and 4, the flat tv of the embodiment of the present application further includes a camera lifting mechanism 3, and the camera lifting mechanism 3 may include a bracket assembly 31, a guide rod 32, and a camera assembly 33. Since the upper side of the main housing 22 of the flat tv is provided with the camera opening 25, the camera lifting mechanism 3 can be installed at an upper position in the installation space, and the camera assembly 33 is aligned with the camera opening 25, so that the camera assembly 33 is extended upward or retracted downward from the camera opening 25.

Further, the camera lifting mechanism 3 may be mounted on the rear side of the main casing plate 22 near the upper side edge. At this time, in order to make the rear side of the main housing plate 22 flush, a groove may be provided in advance at a position above the middle of the rear side of the main housing plate 22, and the camera lifting mechanism 3 may be installed in the groove so that the rear side wall of the camera lifting mechanism 3 is approximately flush with the rear side wall of the main housing plate 22. Alternatively, the camera elevating mechanism 3 may be attached to the rear side of the main casing plate near the left or right edge. This is not a limitation of the present application.

With continued reference to fig. 4, the bracket assembly 31 may include a bracket 311 and a plurality of engaging lugs 312, wherein the circumference of the bracket 311 is connected to the engaging lugs 312. Thus, through holes may be formed in the connection lugs 312, and each connection lug 312 may be screwed into a predetermined threaded hole of the main shell 22 (shown in fig. 2), thereby fixedly connecting the bracket to the main shell 22. In addition, each of the engaging lugs 312 may be bound to a predetermined through hole of the main case 22 by a binding band. Alternatively, the engaging lug 312 may be fixed to the main housing 22 by bonding, or the connecting bracket 311 may be directly bonded to the main housing 22. The connection and installation of the bracket and the main shell plate 22 can be realized.

Illustratively, the number of the guide bars 32 may be two, and the two guide bars 32 are parallel to each other and are respectively located at the left and right sides of the bracket 311. The guide rods 32 extend in the up-down direction, and the upper and lower ends of each guide rod 32 are connected to the upper and lower sidewalls of the bracket 311, respectively. The number of the guide rods 32 may be one, three, or four, which is not limited herein. When the number of the guide bars 32 is plural, each of the guide bars 32 is parallel to each other, as is parallel to the up-down direction (i.e., the first direction).

With continued reference to fig. 4, in some embodiments, camera head assembly 33 may include a lift platform 331, a linkage 332, and a camera head 333. The lifting platform 311 may be provided with guide through holes 3341 along the vertical direction corresponding to the two guide rods 32. Thus, referring to fig. 5, the two guide rods 32 can be respectively inserted through the guide through holes 3341 in the vertical direction, so that the lifting platform 331 is slidably connected to the guide rods 32. Since the length of the guide bar 32 is generally parallel to the up-down direction, the lifting platform 331 can slide in the up-down direction.

In other embodiments, when there are a plurality of guide rods 32, for example, two guide rods 32 are spaced apart. In this case, the lifting platform 331 may be provided with slide grooves in two opposite directions, and the two guide bars 32 may hold the lifting platform 331 at an intermediate position by the two slide grooves having opposite openings, so that the lifting platform 331 may slide in the vertical direction with respect to the guide bars 32.

Illustratively, as shown in fig. 4, a connecting rod mounting hole 3342 is further opened on the upper side of the lifting platform 331. Referring to fig. 5, the lower end of the link 332 is inserted into the link mounting hole 3342 and rotatably coupled to the lifting platform 331 so that the link 332 can rotate relative to the lifting platform 331 in the circumferential direction thereof. The upper end of the corresponding link 332 may be connected with the camera 333. In this way, when the lifting platform 331 slides in the vertical direction relative to the guide bar 32, the connecting rod 332 and the camera 333 can be driven to move synchronously in the vertical direction.

Illustratively, the lower end of the connecting rod 332 may be provided with external threads, and corresponding internal threads corresponding to the external threads of the connecting rod 332 may be provided in the connecting rod mounting hole 3342. Thus, the connecting rod 332 is rotatable about its circumferential direction with respect to the connecting rod mounting hole 3342 and is fixed to the connecting rod mounting hole 3342 in the vertical direction by the combination of the internal thread and the external thread. Alternatively, the link mounting hole 3342 may be a through hole through which the lower end of the link 332 may pass downward, and then a stopper structure is coupled to the lower end of the link 332, thereby preventing the link 332 from being separated upward from the link mounting hole 3342, and also allowing the link 332 to rotate in the circumferential direction of the link mounting hole 3342. Alternatively, the link 3342 is directly placed in the link mounting hole 3342, and the link 332 is rotated in the circumferential direction of the link mounting hole 3342 without being separated upward from the link mounting hole 3342 to some extent by the weight of the camera 333 and the link 332.

In some embodiments, referring to fig. 4, camera head assembly 33 may further include a reset 335. Wherein, the reset element 335 may be a spring and is sleeved on the lower end of the connecting rod 332. When the lower end of the link 332 is inserted into the link mounting hole 3342, the spring is also inserted into the link mounting hole 3342. Since both ends of the spring are engaged with the inner walls of the connecting rod 332 and the connecting rod mounting hole 3342, respectively. In this way, the spring can apply a circumferential restoring force to the connecting rod 332 along the circumferential direction of the connecting rod 332, so that the connecting rod 332 can rotate clockwise or counterclockwise. In addition, the restoring member 335 may also be a rubber band, the rubber band may be wound around the lower end of the connecting rod 332 along the circumferential direction of the connecting rod 332 and is in a stretching state, and both ends of the rubber band may be connected to the connecting rod 332 and the connecting rod mounting hole 3342 or the lifting platform 331 respectively, and may also apply a circumferential restoring force to the connecting rod 332 along the circumferential direction of the connecting rod 332.

The camera 333 is lifted upwards during use, so that the camera 333 is far away from the bracket 311 and the main casing 22 and is not shielded by the display panel 1. Thus, the extended camera 333 can capture image information in a range of angles in front of the flat panel television. When the camera 333 is not needed, the camera 333 moves downward and retracts into the installation space or the bracket 311 to be hidden and stored, so that the appearance of the flat tv is more smooth and attractive, and the camera 333 is protected from being damaged.

To improve the protection effect of the camera head 333, as shown in fig. 5, the camera head assembly 33 may further include a protective shell 336 and a support piece 337. Referring to fig. 6, the protective case 336 may define a receiving cavity 3344 having a viewing window 3343 at a front side thereof, so that the camera 33 may be positioned in the receiving cavity 3344 to be covered by the protective case 336, thereby protecting the camera 33 from external force. Meanwhile, due to the existence of the front side visible window 3343, the lens of the camera 333 can be aligned with the visible window 3343, and the camera cannot be influenced to acquire external image information.

For example, the protective shell 336 and the camera 333 may be located above the upper sidewall of the bracket 311, and the upper and lower ends of the support 337 may be fixedly connected to the protective shell 336 and the lifting platform 331, respectively. Such as by screwing, bonding, or an integrally formed structure. Thus, the protective case 336 supported by the support 337 can move synchronously with the camera 333, such as extending upward or retracting downward, and protect the camera from external damage.

It should be noted that, if the camera 333 is located above the upper side wall of the bracket 311, a notch or a through hole may be formed on the upper side wall of the bracket 311, so that the upper end of the connecting rod 332 passes through the upper side wall of the bracket 311 upward. If the camera 333 and the protective casing 336 are partially or even completely located below the upper sidewall of the bracket 311 in the retracted state, the upper sidewall of the bracket 311 may be provided with a receiving groove or a receiving notch from top to bottom for receiving and hiding the camera 333 and the protective casing 336.

During the movement of the camera head assembly 33 along the guide bar 32 in the up-and-down direction, the user can pull up or push down the protective shell 336 to drive the camera head assembly 33 to extend upward or retract downward. In addition, a driving device can be provided to drive the camera assembly 33 to automatically extend upwards or retract downwards.

Illustratively, as shown in fig. 7, the camera lifting mechanism 3 may further include a driving assembly 34, and the driving assembly 34 may include a lead screw 341, a driving motor 342, and a reduction gear set 343. Referring to fig. 8, the driving motor 342 may be mounted on the bracket 311 with an output shaft of the driving motor 342 inserted downward into the transmission chamber 313. The upper and lower ends of the lead screw 341 may be rotatably connected to the upper and lower sidewalls of the bracket 311, respectively, and the lower end of the lead screw is also inserted downward into the transmission chamber 313. The reduction gear set 343 may include a driving gear 3431, a driven gear 3432, a first reduction gear 3433, and a second reduction gear 3434. The driving gear 3431 may be in transmission connection with an output shaft of the driving motor 342, and the driven gear 3432 may be in transmission connection with a lower end of the lead screw 341. Between the driving gear 3431 and the driven gear 3432, the driving gear 3431 may mesh with an input of a primary reduction gear 3433, an output of the primary reduction gear 3433 may mesh with an input of a secondary reduction gear 3434, and an output of a secondary acceleration gear 3434 meshes with the driven gear 3432. Thus, when the driving motor 342 drives the output shaft to rotate at a high speed, the screw rod 341 can be driven to rotate slowly through the transmission of the reduction gear set 343.

Because the lifting platform 331 is further provided with a screw rod threaded hole, and the screw rod 341 is provided with a corresponding external thread. Thus, the lead screw 341 can pass through the lead screw thread hole along the up-down direction and be in transmission fit with the lead screw thread hole. Thus, when the lead screw 341 is driven by the driving motor 342 to rotate slowly, as shown in fig. 7, from top to bottom, and when the lead screw 341 rotates clockwise, the lead screw 341 can drive the lifting platform to lift upwards in cooperation with the threaded hole of the lead screw, so that the camera module 33 can extend upwards. Similarly, from top to bottom, when the screw 341 rotates counterclockwise, the screw 341 can drive the lifting platform to descend in cooperation with the screw hole, so that the camera assembly 33 can retract and hide downward.

The driving motor 342 is generally a rotating motor, so that the rotating speed is high. Therefore, the screw 341 is driven by the rotation motor to slowly rotate through the reduction gear set 343, so that the camera head assembly 33 can be smoothly raised or lowered. In addition, the driving motor 342 may also be a stepping motor, and at this time, the output shaft of the driving motor 342 and the lower end of the lead screw 341 may also be directly connected through a coupler, and since the stepping motor may precisely control the rotation angle, it is convenient to precisely control the ascending or descending amplitude of the camera head assembly 33.

In some embodiments, as shown in fig. 8 and 9, wherein fig. 9 is a partially enlarged schematic view at a in fig. 8. Camera head assembly 33 may also include a first guide structure 338, and first guide structure 338 may include guide post 3381 and sleeve 3382. One end of the guiding post 3381 is fixedly connected to the outer side wall of the sleeve 3382, and the guiding post 3381 can extend along the radial direction of the sleeve 3382 away from the center of the sleeve. Illustratively, the end of the guide post 3381 distal from the sleeve 3382 may be a ball-shaped structure. When the first guide structure 338 is installed, the lower end of the link 332 may be inserted into the sleeve 3382 so that the link 332 may be rotated in synchronization with the sleeve 3382. In addition, one end of the guide post 3381 may be directly fixedly connected to the position of the connecting rod 332 near the lower end, for example, by welding. The length of the guide post 3381 may generally coincide with the radial direction of the connecting rod 332.

With continued reference to fig. 9, the bracket assembly 31 further includes a retaining plate 314, and the retaining plate 314 is adjacent to the connecting rod 332 and fixedly connected to the bracket 311. The limiting plate 314 may be opened with a first guide groove 315 towards one side of the connecting rod 332, and the first guide groove 315 extends along the up-down direction.

The camera 333 and the link 332 shown in fig. 8 and 9 are in the fully retracted state. At this time, one end of the guide post 3381 remote from the connecting rod 332 is positioned in the first guide groove 315. And the end of the guide post 3381 located in the first guide groove 315 is generally spherical, which reduces the contact surface with the first guide groove 315, thereby reducing friction.

When the lifting platform 331 is lifted to drive the connecting rod 332, the camera 333 and the guiding post 3381 to move upwards, one end of the spherical structure of the guiding post 3381 can move upwards along the inner wall of the first guiding groove 315. Therefore, the first guide groove 315 and the guide post 3381 are engaged, so that the camera 333 and the link 332 do not rotate to the left or the right when moving in the vertical direction.

During the movement of the end of the guide post 3381 remote from the connecting rod 332 in the first guide groove 315, the camera 333 is generally oriented in the same direction during the raising or lowering. Illustratively, the camera 333 may face right in front, i.e., in the same direction as the imaging side of the display panel 1. Alternatively, the camera 333 may be oriented in the left direction from the front, or the camera 333 may be oriented in the right direction from the front. For example, the vertical projection of the connecting rod 332 on the position-limiting plate 314 may be located on the right side of the first guide groove 315, that is, when the guide post 3381 is located in the first guide groove 315, as shown in fig. 8, the camera 333 faces a direction just forward and to the right. At this time, the longitudinal direction of the guide post 3381 is shifted to the right rear left.

When the end of the guide post 3381 away from the connecting rod 332 moves to the uppermost end in the first guide slot 315, as shown in fig. 10 and 11, fig. 11 is a partially enlarged view of B in fig. 10. At this time, the bracket assembly 31 may further include a second guiding structure 316, and the second guiding structure 316 may be a second guiding groove 3161 opened on the limiting plate 314, and the second guiding groove 3161 is located on a side of the limiting plate 314 facing the connecting rod 332. For example, along the length direction of the second guide groove 3161, an angle formed by a connection line between two ends of the second guide groove 3161 and the vertical direction may be an acute angle or an obtuse angle, which is not limited herein. It is only necessary to communicate the lower end of the second guide groove 3161 with the upper end of the first guide groove 315. So that the angle between the second guide groove 3161 and the first guide groove 315 is an obtuse angle.

As shown in fig. 10 and 11, when the lifting platform 331 continues to ascend, the end of the guide post 3381 distant from the link 332 starts to enter the second guide groove 3161. At this time, the camera 333 is in the first preset position, that is, the camera 333 rotates when being raised, and the camera 333 does not rotate when not moving or being lowered. Because the second guiding groove 3161 inclines rightward in the up-down direction, the connecting rod 332 is driven by the guiding post 3381 to rotate clockwise from top to bottom in the process of moving upwards continuously under the limit of the second guiding groove 3161 and the cooperation of the guiding post 3381, that is, the camera 333 begins to deflect leftwards.

Illustratively, as shown in FIG. 12, FIG. 12 is a front view of the bracket assembly 31. The limiting block is further provided with an avoiding groove 317, and in combination with fig. 5, the vertical projection of the connecting rod 332 on the limiting block 314 generally overlaps the avoiding groove 317. That is, the longitudinal direction of the escape groove 317 is parallel to the up-down direction.

Thus, when the link 332 is attached, the link 332 can be brought as close to the stopper plate 314 as possible by avoiding the provision of the groove 317. And the larger diameter sleeve 3382 can be prevented from contacting the limit plate 314.

In some embodiments, with continued reference to fig. 12, the first guide slot 315 may be located to the left of the escape slot 317. The left and right ends or the lower and upper ends of the second guide groove 3161 are respectively located at the left and right sides of the escape groove 317. For example, the second guide groove 3161 may include a first groove 31611, a second groove 31612, and a third groove 31613, which are sequentially connected. Wherein, the left end of the first segment groove 31611 is also communicated with the upper end of the first guide groove 315. The two-stage groove 31612 extends in the up-down direction. And the included angles between the second segment groove 31612 and the first segment groove 31611 and between the third segment groove 31613 are obtuse angles respectively.

Thus, the camera 333 is continuously deflected to the left while the guiding post 3381 is moving in the groove 31611 and the camera is synchronously raised. When the guide post 3381 moves in the second groove 31612 and the camera 33 is lifted synchronously, the camera is in the second predetermined position range, and the camera 333 is not deflected but lifted while maintaining the same angle. When the guide post 3381 moves in the three-segment groove 31613 and the camera 333 ascends in synchronization, the camera 333 continues to deflect leftward.

Illustratively, as shown in fig. 12, in the case where the escape groove 317 overlaps the two-stage groove 31612, and in the case where the longitudinal direction of the guide post 3381 is collinear with the direction in which the lens of the camera 333 is directed, and the direction in which the lens of the camera 333 is directed is diametrically opposite to the one end of the spherical structure of the guide post 3381.

Since the camera 333 is initially in a state of being tilted right to the front, the camera 333 is continuously tilted left while the guide post 3381 moves in the second guide groove 3161. If the second guiding groove 3161 is long enough, the camera 333 will rotate to face right ahead first, and the camera 333 is at the second predetermined position. The camera 333 then continues to rotate to the left to direct the camera to a position just to the left of the front, until the guide post 3381 moves to the end of the second guide groove 3161, at which point the camera 333 is in a fully extended state.

As shown in fig. 13 and 14, wherein fig. 14 is a partially enlarged schematic view at C in fig. 13. At this time, the spherical end of the guide post 3381 is located in the two-stage groove 31612, that is, the camera 333 is within the range of the second preset position, and the lens of the camera 333 is directed generally straight ahead.

As shown in fig. 15 and 16, wherein fig. 16 is a partially enlarged schematic view at D in fig. 15. At this time, the spherical end of the guide post 3381 is positioned in the three-stage groove 31613, and the spherical end abuts against the left side wall and the upper side wall of the three-stage groove 31613, respectively. I.e., when the camera head 333 is in a fully extended state. And the lens of the camera 333 is generally oriented to the left in the front direction.

In summary, in the above embodiment, during the process of lifting the camera head assembly 33, the first guide groove 315 is first engaged with the guide post 3381 in a limiting manner, so that the camera head 333 can extend upwards, during which the camera head does not rotate, but the initial position of the camera head 333 can be shifted to the right. When the camera continues to ascend, so that the guide post 3381 moves into the second guide groove 3161 and moves in the section of groove 31611, the camera 333 synchronously deflects leftwards due to the limit of the second guide groove 3161 in the ascending process. When the camera continues to ascend so that the guide post 3381 moves into the two-stage groove 31612, the camera 333 may not deflect during the ascent, even directing the lens straight ahead. Finally, as the camera continues to rise, moving the guide post 3381 into the three-segment groove 31613, the camera 333 may continue to deflect to the left during the rise until the camera 333 is in a fully extended state. When the camera 333 moves down in the reverse direction, the motion state is reversed.

Therefore, in the process that the camera lifting mechanism 3 provided by the embodiment of the present application ascends or descends the camera assembly 33, only one driving device is needed to drive the lifting platform 331 to ascend or descend, and the adjustment of the rotation angle of the camera 333 can be synchronously realized. Compared with the technical scheme that two driving motors are used for controlling lifting and rotating respectively, the driving assembly can be saved, the requirement for simultaneously controlling the lifting and steering of the camera is met, the structure is simple, the occupied space of equipment is reduced, and the production and manufacturing cost is saved.

It should be noted that, in the embodiment of the present application, the extending height of the camera 333 is adjusted, or the lifting stroke of the camera 333 is lowered. It is also possible to provide only the second guide groove 3161 without providing the first guide groove 315. The first guiding structure 338 may also be a groove-like structure (e.g., a second guiding groove) provided on the connecting rod 332, and the second guiding structure 316 may be correspondingly configured to be a column-like structure (e.g., a guiding column) correspondingly clamped with the groove-like structure, and may be adjusted and configured in combination with the above embodiments, and the effect of synchronous rotation in the lifting process of the camera 333 may also be achieved. And will not be described in detail herein.

When the first guiding structure 338 is the guiding post 3381 connected to the connecting rod 332 and the second guiding structure 316 is the second guiding groove 3161 opened on the limiting plate 314, a circumferential restoring force can be applied to the connecting rod 332 through the restoring member 335, so that one end of the guiding post 3381 far away from the connecting rod 332 can always adhere to the side walls of the second guiding groove 3161 and the first guiding groove 315 to slide. Thus, under the action of the restoring force, one end of the guide post 3381 far away from the connecting rod 332 is attached to only one of the side walls of the first guide groove 315 or the second guide groove 3161, and does not swing left and right in the first guide groove 315 or the second guide groove 3161. Therefore, it is possible to avoid a shake of the link 332 in the circumferential direction to cause a problem that the camera 333 cannot stably focus.

In addition, when the first guiding structure 338 is a slot-like structure (e.g., a second guiding slot) opened on the connecting rod 332, and the second guiding structure 316 is correspondingly configured as a column-like structure (e.g., a guiding column) correspondingly engaged with the slot-like structure. The restoring member 335, which is mounted to the lower end of the connecting rod 332, also allows the second guide structure to always contact the sidewall of the first guide structure. That is, it is also possible to avoid a problem that the link 332 swings in the circumferential direction to cause the camera 333 not to be able to stably focus.

In the description herein, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
