A television is widely used in daily life as a common electrical appliance, and based on this, as shown in fig. 1, the present utility model provides a display device 10, where the display device 10 includes a display screen assembly 100, and the display screen assembly 100 is used for displaying pictures. A user may view a display through the display assembly 100.

In order to realize man-machine interaction, as shown in fig. 1, the utility model provides a display device 10, which further comprises a camera assembly 200, wherein the camera assembly 200 is arranged on a display screen assembly 100 and is electrically connected with the display screen assembly 100, information interaction can be carried out between the camera assembly 200 and the display screen assembly 100, and the camera assembly 200 shoots and the display screen assembly 100 displays, and the camera assembly 200 and the display screen assembly cooperate to realize man-machine interaction.

As shown in fig. 2, the camera module 200 includes a lens 210 and a lens holder 220, a lens hole 222 is formed in the lens holder 220, the lens 210 is disposed in the lens hole 222, and the lens 210 can take images of the outside through the lens hole 222.

The presence of the camera assembly 200 presents problems in that the camera assembly 200 may be hacked, thereby violating the privacy of the user.

In order to solve the above-mentioned problems, in the related art, it is general that a user manually moves a shutter to shield a lens 210 of a camera or rotates the camera so that the user is not within a photographing range of the lens 210 of the camera, thereby avoiding privacy leakage of the user.

However, the manual operation is troublesome, and it is difficult for the user to contact the camera assembly 200 when the camera assembly 200 is at a high position, so that the degree of intellectualization thereof is low.

Based on this, as shown in fig. 2, the camera module 200 of the present utility model further includes a rotating ring 230, a plurality of blocking pieces 240, a plurality of elastic members 250, and a driving device 260.

The lens base 220 is provided with a groove 221, the groove 221 is communicated with a lens hole 222, and the lens hole 222 is positioned on the bottom of the groove 221; as shown in fig. 3, the rotating ring 230 is disposed in the groove 221 and can rotate between a first limit position and a second limit position; the blocking piece 240 is disposed in the cavity, and is rotatable along a rotation direction of the rotation ring 230 to open or close the lens hole 222; the elastic piece 250 is arranged in the groove 221, the elastic piece 250 is connected between each baffle 240 and the lens holder 220, one end of the elastic piece 250 is fixedly connected with the baffle 240, the other end of the elastic piece 250 is fixedly connected with the lens holder 220, and different elastic pieces 250 are different in fixing positions with the lens holder 220; the driving device 260 is used for driving the rotating ring 230 to rotate;

as shown in fig. 3, in the case that the rotating ring 230 is rotated from the first limit position to the second limit position, the plurality of blocking pieces 240 are rotated to open the lens hole 222 by the rotating force of the rotating ring 230, and the elastic member 250 is in an elastically deformed state; as shown in fig. 4, in the case that the rotation ring 230 is rotated from the second limit position to the first limit position, the plurality of blocking pieces 240 are rotated to close the lens hole 222 by the elastic member 250.

With the above arrangement, since the driving device 260 can drive the rotation ring 230 to rotate, as shown in fig. 3, when the lens hole 222 needs to be opened, the driving device 260 is started, and the driving device 260 is used to drive the rotation ring 230 to rotate from the first limit position to the second limit position (along the direction of the anticlockwise arrow in fig. 3) so as to drive the plurality of blocking pieces 240 to rotate, thereby opening the lens hole 222, so that the lens 210 of the camera assembly 200 in the lens hole 222 is exposed to the outside for normal operation.

When the lens hole 222 needs to be closed, the driving device 260 is started, as shown in fig. 4, the driving device 260 is used to drive the rotating ring 230 to rotate from the second limit position to the first limit position (along the direction of the clockwise arrow in fig. 4), so that the rotating ring 230 is reset, and the elastic member 250 is elastically deformed in the process of rotating the rotating ring 230 from the first limit position to the second limit position, so that the elastic member 250 can drive the baffle 240 to rotate to close the lens hole 222 under the action of the elastic force of the elastic member 250, thereby protecting the privacy of the user.

The lens hole 222 is automatically closed and opened by utilizing the cooperation of the driving device 260 and the elastic piece 250, so that the intelligent degree is high, and the lens hole is simple and convenient.

And, only when the lens hole 222 is opened, the blocking piece 240 is driven to rotate by the driving force of the driving device 260 to open the lens hole 222, and when the lens hole 222 is closed, the blocking piece 240 is driven to rotate by the elastic force of the elastic piece 250 to close the lens hole 222, so that the blocking piece 240 is prevented from being blocked mutually when the lens hole 222 is closed, and the stable performance of the camera assembly 200 is ensured.

It can be appreciated that the lens 210 is generally cylindrical, and thus the lens hole 222 may be correspondingly configured to be circular, such that the lens hole 222 is compatible with the lens 210.

In this case, when the lens holes 222 are closed by using the five baffles 240, each baffle 240 covers one fifth of the lens 210 in a plane parallel to the plane of the rotating ring 230, that is, each baffle 240 occupies 72 °, and at this time, the five baffles 240 can also rotate synchronously, so as to avoid mutual interference between the five baffles 240.

In addition, the rotating ring 230 may be located at a side of the blocking piece 240 away from the bottom of the groove 221, or the rotating ring 230 may be located between the blocking piece 240 and the bottom of the groove 221.

On this basis, in order to save space in the groove 221, as shown in fig. 4, the plane of the rotating ring 230 is parallel to the bottom of the groove 221, so that the space of the groove 221 in the direction perpendicular to the bottom of the groove 221 can be reduced, so that the baffle 240, the rotating ring 230 and other components in the groove 221 are tightly matched, the overall volume of the lens holder 220 can be reduced, the camera module 200 is miniaturized, and the appearance of the camera module is attractive.

Of course, a certain angle may be formed between the plane of the rotating ring 230 and the bottom of the groove 221.

Illustratively, in order to drive the rotating ring 230 to rotate by the driving device 260, as shown in fig. 5, a plurality of gear teeth 231 are formed on the rotating ring 230, and the plurality of gear teeth 231 are sequentially distributed along the rotating direction of the rotating ring 230; the driving device 260 includes a gear 261 and a power member 262, wherein the gear 261 is disposed in the groove 221 and meshed with the plurality of gear teeth 231; the power piece 262 is fixed on the lens base 220, and an output shaft of the power piece 262 is in transmission connection with the gear 261.

Through the engagement of the gear 261 and the gear teeth 231, a transmission relationship is established between the gear 261 and the rotating ring 230, so that when the power piece 262 drives the gear 261 to rotate, the gear 261 can drive the rotating ring 230 to rotate, and the rotating ring 230 can rotate from the first limit position to the second limit position to drive the baffle 240 to rotate so as to open the lens hole 222.

The power member 262 may be an electric motor, or may be a motor.

In addition, the gear teeth 231 may be formed on the inner wall surface of the rotating ring 230, that is, the gear 261 is engaged with the rotating ring 230, and since the rotating ring 230 has the annular hole, there is no need to separately reserve space for the arrangement of the gear 261, so that the space in the groove 221 can be saved, thereby reducing the overall volume of the lens holder 220, miniaturizing the camera assembly 200, and making the appearance thereof attractive.

Of course, the rotating ring 230 and the gear 261 may be externally engaged, that is, the gear teeth 231 are formed on the outer wall surface of the rotating ring 230, in which case a space needs to be reserved between the rotating ring 230 and the circumferential wall surface of the groove 221 so that the gear 261 can be engaged with the gear teeth 231.

In some embodiments, since the power member 262 has a larger volume, as shown in fig. 5, a through hole is formed in the lens holder 220 and is located on the bottom of the groove 221, the power member 262 is fixed on the lens holder 220, and the power member 262 is located outside the groove 221, and then an output shaft of the power member 262 extends into the groove 221 through the through hole and is in transmission connection with the gear 261 in the groove 221, so as to drive the gear 261 to rotate, and further drive the rotating ring 230 to rotate.

Since the power member 262 is disposed outside the recess 221, the power member 262 does not occupy the space in the recess 221, so that the overall volume of the lens mount 220 can be reduced, and the camera module 200 can be miniaturized, thereby having an attractive appearance.

Of course, the power member 262 may also be disposed in the recess 221.

On this basis, in order to facilitate the fixing of the power member 262 to the lens mount 220, as shown in fig. 6, the above-mentioned camera assembly 200 further includes a fixing bracket 263, and the fixing bracket 263 is fixed to the lens mount 220 and is located outside the recess 221, and then the power member 262 is fixed to the fixing bracket 263. The power piece 262 is fixed on the lens base 220 by the fixing bracket 263, and the position and the arrangement mode of the power piece 262 can be randomly adjusted, so that the arrangement and the fixation of the power piece 262 are convenient.

In some embodiments, in order to enable the rotation of the rotation ring 230 within the groove 221 smoothly, as shown in fig. 7, a gap 271 is provided between the outer circumferential wall surface of the rotation ring 230 and the circumferential wall surface of the groove 221; the camera assembly 200 further includes a plurality of first rollers 270 disposed at intervals along the circumference of the rotating ring 230, the first rollers 270 are fixedly connected with the rotating ring 230, and the first rollers 270 are at least partially located in the gaps 271, and a peripheral wall portion of the first rollers 270 contacts with a peripheral wall surface of the groove 221.

Since the gap 271 is provided between the outer circumferential wall surface of the rotating ring 230 and the circumferential wall surface of the groove 221, the rotating ring 230 does not contact the circumferential wall surface of the groove 221 during rotation, friction is not generated between the rotating ring 230 and the circumferential wall surface of the groove 221, and thus the rotating ring 230 can rotate more smoothly.

However, since the existence of the gap 271 may shake the rotating ring 230 with respect to the groove 221 in the radial direction thereof, by disposing the first roller 270 in the gap 271 such that a portion of the first roller 270 contacts the peripheral wall surface of the groove 221, the shaking of the rotating ring 230 can be avoided, and since the existence of the first roller 270, the first roller 270 and the peripheral wall surface of the groove 221 are in line contact, so that the friction force therebetween is small, and the smoothness of the rotation of the rotating ring 230 can be ensured.

The plurality of first rollers 270 may be uniformly disposed around the rotating ring 230, so that the friction force between the first rollers 270 and the circumferential wall surface of the groove 221 is more uniform along the circumferential direction of the rotating ring 230, and thus the rotating ring 230 will not be jammed due to uneven friction force during the rotation of the rotating ring 230, thereby ensuring the smoothness of the rotation of the rotating ring 230.

Of course, the plurality of first rollers 270 may be unevenly disposed about the rotating ring 230.

In addition, the first rollers 270 may be provided in two or four or five, and the present utility model is not particularly limited thereto.

And the first roller 270 and the rotating ring 230 can be in an integrated structure, so that the structural strength between the rotating ring 230 and the first roller 270 can be enhanced, and secondary processing can be avoided, so that the processing is simpler and more convenient. Of course, the first roller 270 and the rotating ring 230 may be separated, and the rotating ring 230 and the first roller 270 may be separately manufactured and then fixed together by welding or other suitable techniques.

On this basis, the camera assembly 200 further includes a lens cover, a through hole is formed in the lens cover, the lens cover is fastened to the lens holder 220 and is fixedly connected with the lens holder 220, and a cavity is formed with the groove 221, so that the rotating ring 230 is fastened in the groove 221, the through hole can ensure that the lens 210 can capture an external environment, and the lens cover and the lens holder 220 can be fastened in the groove 221 by matching, so that the rotating ring 230 is prevented from swinging along a direction perpendicular to a plane in which the rotating ring is located in a rotating process.

Meanwhile, the baffle 240, the rotating ring 230 and other parts can be sealed in the groove 221 to protect the components from damage, and the whole camera assembly 200 is attractive.

On this basis, since the rotating ring 230 is excessively stressed at the position where the gear 261 is engaged with the power member 262, as shown in fig. 8, a plurality of gear teeth 231 are formed on the inner circumferential wall surface of the rotating ring 230; the camera assembly 200 further includes at least one second roller 280 disposed in the groove 221 and fixedly connected to the lens holder 220, wherein the second roller 280 is at least partially disposed in the gap 271, and the second roller 280 and the gear teeth 231 are sequentially arranged along the radial direction of the rotating ring 230.

With the above arrangement, the friction between the outer circumferential wall surface of the rotating ring 230 and the circumferential wall surface of the groove 221 is reduced by the second roller 280, so that the rotation of the rotating ring 230 is smoother. Meanwhile, the meshing position of the gear 261 and the rotating ring 230 can be well slowed down, and the rotating ring 230 and the gear 261 shake due to the driving force of the power piece 262, so that the stability of the transmission of the gear 261 and the rotating ring 230 is ensured, and the overall reliability of the camera assembly 200 is improved.

The second rollers 280 may be one or two, and the two second rollers 280 may be spaced apart along the rotation direction of the rotation ring 230.

In addition, the second roller 280 and the lens holder 220 can be integrally formed, so that the structural strength between the lens holder 220 and the second roller 280 can be enhanced, and secondary processing can be avoided, so that the processing is simpler and more convenient. Of course, the second roller 280 and the lens holder 220 may be in a separate structure, and the lens holder 220 and the second roller 280 may be separately manufactured and then fixed together by a suitable technique such as welding.

In order to enable the baffle plates 240 to rotate relative to the lens holder 220, as shown in fig. 9, each baffle plate 240 is provided with a rotation hole 241, and a plurality of rotation holes 241 are arranged at intervals along a rotation direction of the rotation ring 230;

the camera assembly 200 further includes a plurality of rotation shafts 242 disposed in one-to-one correspondence with the rotation holes 241, wherein the rotation shafts 242 are disposed in the grooves 221, one end of each rotation shaft 242 is fixedly connected with a bottom of each groove 221, and the other end of each rotation shaft 242 extends into the corresponding rotation hole 241, so that the blocking piece 240 can rotate around the corresponding rotation shaft 242.

Through the cooperation of the rotation shaft 242 and the rotation hole 241, the blocking piece 240 can open the lens hole 222 under the driving of the rotation ring 230, so that the blocking piece 240 can close the lens hole 222 under the action of the elastic piece 250. The hole shaft is simple in matching structure and easy to manufacture and process.

It can be appreciated that the plurality of rotation holes 241 are uniformly arranged at intervals along the rotation direction of the rotation ring 230 in order to make the rotation angle of each of the blocking pieces 240 uniform. Therefore, each baffle 240 can synchronously rotate, the rotation amplitude is consistent, the coordination among a plurality of baffles 240 is high, and the probability of the fault of the camera assembly 200 is reduced.

Illustratively, the plane of the rotating ring 230 is parallel to the bottom of the groove 221, and the rotating shaft 242 is arranged along the direction perpendicular to the bottom of the groove 221, so that the plurality of baffle plates 240 and the rotating ring 230 can rotate on the plane parallel to the bottom of the groove 221, and the design, processing and installation difficulties can be reduced.

On this basis, in order to drive the baffle 240 to close the lens hole 222 by using the elastic member 250, as shown in fig. 9, the elastic member 250 includes a torsion spring 251, each rotation shaft 242 is sleeved with the torsion spring 251, one end of the torsion spring 251 is fixed with the lens holder 220, and the other end of the torsion spring 251 is fixed with the baffle 240.

The torsion spring 251 is sleeved on the rotating shaft 242, so that the torsion spring 251 can be prevented from shaking in a large range, the stability of the elastic deformation of the torsion spring 251 is ensured, each baffle 240 can synchronously rotate when the torsion spring 251 is utilized to drive the baffle 240 to rotate, the plurality of baffles 240 are prevented from being blocked during rotation, and the running stability of the camera module 200 is ensured.

Wherein each rotation shaft 242 may be sleeved with only one torsion spring 251. Or, a plurality of torsion springs 251 may be sleeved on each rotation shaft 242, in this case, the number of torsion springs 251 sleeved on each rotation shaft 242 may be unequal, and compared with this, the number of torsion springs 251 sleeved on each rotation shaft 242 may be equal, so that the elastic deformation of the torsion springs 251 is ensured to be consistent, so that synchronous rotation of the plurality of baffles 240 may be ensured.

In addition, in order to fix the torsion spring 251 and the lens holder 220, as shown in fig. 10, a clamping groove 223 is formed on the lens holder 220, for example, a clamping groove 223 is formed at the bottom of the groove 221, and one end of the torsion spring 251, which is fixed to the lens holder 220, is clamped in the groove 221, so as to fix the torsion spring 251 and the lens holder 220, and prevent the end of the torsion spring 251 from moving, thereby ensuring that the torsion spring 251 can elastically deform during the rotation of the baffle 240. Since the engagement between the torsion spring 251 and the catching groove 223 is a catching engagement, the installation and the removal of the torsion spring 251 can be facilitated. Of course, the end of the torsion spring 251 may be directly welded to the lens holder 220.

In order to fix the other end of the torsion spring 251 on the baffle 240, a groove may be formed on the baffle 240 to clamp the end of the torsion spring 251 in the groove, or the end of the torsion spring 251 may be directly welded on the baffle 240.

For example, in order to stably sleeve the torsion spring 251 on the rotation shaft 242, the torsion spring 251 is disposed between the corresponding baffle 240 and the bottom of the groove 221, so that the baffle 240 and the lens holder 220 can be used to sandwich the torsion spring 251, and shake of the torsion spring 251 along the axis of the rotation shaft 242 during elastic deformation can be avoided, thereby ensuring the stability of the overall operation of the camera assembly 200.

In some embodiments, the elastic member 250 may also include a spring, where one end of the spring is fixedly connected to the lens holder 220, and the other end of the spring is fixedly connected to the blocking piece 240, for example, by welding.

Of course, the elastic member 250 may be any other suitable elastic object, which is not specifically described herein.

Through the cooperation of the linkage post 290 and the baffle 240, the baffle 240 is driven to rotate to open the lens hole 222, so that the baffle 240 can be conveniently detached. Meanwhile, when the rotary ring 230 rotates clockwise in fig. 11, the rotation of the rotary ring 230 does not affect the blocking piece 240, so that the blocking piece 240 can be guaranteed to rotate under the action of the elastic piece 250 to close the lens hole 222. Therefore, the blocking of the plurality of blocking pieces 240 when the lens hole 222 is closed can be avoided, and the stability of the movement of the camera assembly 200 is ensured.

In order to make the linkage post 290 contact with the blocking piece 240, the linkage post 290 may be directly contact with the peripheral wall surface of the blocking piece 240 as shown in fig. 11, and thus, the structure of the blocking piece 240 does not need to be modified, and the structure is simple. Of course, a hole may be formed on the blocking piece 240, and the hole may extend along the rotation direction of the rotating ring 230, and a space may be reserved in the hole, so as to ensure that the rotation of the linkage post 290 will not affect the rotation of the blocking piece 240 when the blocking piece 240 closes the camera under the action of the elastic member 250.

It can be appreciated that in order to limit the rotation of the rotation ring 230 between the first limit position and the second limit position, the limiting hole 310 extends a certain distance in the rotation direction of the rotation ring 230.

Illustratively, as shown in fig. 12, the limiting hole 310 is formed on the lens holder 220 and is located at the bottom of the groove 221, the limiting post 320 is fixed on a sidewall surface of the rotating ring 230 facing the bottom of the groove 221, and the limiting post 320 extends into the limiting hole 310.

By the cooperation of the guide hole 410 and the guide post 420, the blocking piece 240 can be prevented from shaking violently during the rotation process. In addition, when the blocking piece 240 closes the lens hole 222 under the action of the elastic member 250, the guide structure 400 may play a guide role, and it may be ensured that the blocking piece 240 may rotate along a predetermined track, thereby ensuring the stability of the movement of the camera assembly 200.

Alternatively, the number of the guide structures 400 may be smaller than the number of the blocking pieces 240, that is, the guide structures 400 are disposed between a part of the blocking pieces 240 and the lens holder 220.

It can be appreciated that, in order to ensure that the rotating ring 230 can rotate between the first limit position and the second limit position, the extending distance rate of the guide hole 410 in the rotating direction of the rotating ring 230 is greater than the extending distance of the limit hole 310 in the rotating direction of the rotating ring 230.
