[0042] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0043] The actuator according to the embodiment of the utility model is described below with reference to the accompanying drawings.

[0044] like Figure 1-Figure 5 As shown, the actuator according to the embodiment of the utility model includes a base 10 , a mounting base 20 , and a transmission assembly 40 .

[0045] The mounting seat 20 is rotatably disposed on the base 10, and the transmission assembly 40 includes at least one rotating wheel and a transmission belt 42. The transmission belt 42 is sleeved on the rotating wheel, and the rotating wheel rotates to drive the transmission belt 42 to move back and forth. The transmission belt 42 is connected to the mounting seat 20 to drive the mounting seat 20 to rotate when moving, so as to adjust the angle of the mounting seat 20, and then the angle of the mounting seat 20 relative to the user can be adjusted to adjust the mounting seat 20 to a better use position, so that the user can use the mounting seat 20 or the parts on the mounting seat 20 conveniently, so as to meet the requirements of different users for the use position, and to improve the user's comfort.

[0046] In some embodiments, a display screen, microphone, camera or speaker can be set on the mounting base 20. When the mounting base 20 rotates, the mounting base 20 can drive the display screen, microphone, camera or speaker to rotate to adjust the angle of the display screen, microphone, camera or speaker, and then adjust the angle of the display screen, microphone, camera or speaker relative to the user, so as to facilitate the user to use the display screen, microphone, camera or speaker and improve the user experience.

[0047] Specifically, when the mounting seat 20 needs to be rotated in a direction to overcome gravity, the rotating wheel rotates and drives the transmission belt 42 to move, so that the transmission belt 42 can tighten the mounting seat 20 and apply a force to the mounting seat 20 to overcome gravity, so that the mounting seat 20 can rotate in the direction to overcome gravity. When the rotating wheel stops rotating, the transmission belt 42 stops moving to limit the position of the multiple mounting seats 20.

[0048] When the mounting seat 20 needs to be rotated in the direction of gravity, the rotating wheel rotates and drives the transmission belt 42 to move, so that the transmission belt 42 can gradually loosen the mounting seat 20. At this time, under the action of gravity, the mounting seat 20 rotates in the direction of gravity. When the rotating wheel stops rotating, the transmission belt 42 stops moving. At this time, the transmission belt 42 re-tightens the mounting seat 20 to limit the position of the mounting seat 20.

[0049] Therefore, the actuator according to the embodiment of the utility model can adjust the angle of the mounting seat 20 relative to the user so as to adjust the mounting seat 20 to a better use position, making it convenient for the user to use the mounting seat 20 or the components on the mounting seat 20, thereby meeting the requirements of different users for the use position and improving the user's comfort.

[0050] The following describes an actuator according to a specific embodiment of the utility model with reference to the accompanying drawings.

[0051] In some specific embodiments of the present invention, Figure 1-Figure 5 As shown, the actuator includes a base 10 , a mounting base 20 , and a transmission assembly 40 .

[0052] In some embodiments of the present invention, Figure 1 , Figure 2 As shown, there are multiple rotating wheels including a first rotating wheel 411 and a second rotating wheel 412 that are spaced apart. The first rotating wheel 411 and the second rotating wheel 412 are rotatably disposed on the base 10, respectively. The transmission belt 42 is sleeved on the first rotating wheel 411 and the second rotating wheel 412 to be driven to move by at least one of the first rotating wheel 411 and the second rotating wheel 412, and then the transmission belt 42 is used to drive the mounting base 20 to rotate, so as to adjust the angle of the mounting base 20 relative to the user, so that the user can comfortably operate the mounting base 20 or operate the components on the mounting base 20, thereby improving the user experience.

[0053] The transmission belt 42 is placed outside the first rotating wheel 411 and the second rotating wheel 412, so that the first rotating wheel 411 and the second rotating wheel 412 can be used to support the position of the transmission belt 42, and then the reciprocating direction of the transmission belt 42 can be controlled, so that the transmission belt 42 can drive the mounting seat 20 to rotate when reciprocating.

[0054] Specifically, at least one of the first rotating wheel 411 and the second rotating wheel 412 is a driving wheel, and when the driving wheel rotates, it can drive the transmission belt 42 to move, so that the transmission belt 42 drives the mounting seat 20 to rotate. In some embodiments, the first rotating wheel 411 is a driving wheel, and the second rotating wheel 412 is a driven wheel. When the first rotating wheel 411 rotates, it drives the transmission belt 42 to move, and when the transmission belt 42 moves, it can drive the second rotating wheel 412 to rotate. In other embodiments, both the first rotating wheel 411 and the second rotating wheel 412 are driving wheels, and the first rotating wheel 411 and the second rotating wheel 412 rotate in the same direction to jointly drive the transmission belt 42 to move.

[0055] In some optional embodiments of the present invention, the transmission assembly 40 includes a first transmission assembly 40 and a second transmission assembly 40, each of which includes a transmission belt 42 and two rotating wheels arranged at intervals, the transmission belt 42 is sleeved on the corresponding two rotating wheels, the first transmission assembly 40 and the second transmission assembly 40 are arranged on both sides of the rotating shaft 23 of the mounting base 20, and the first transmission assembly 40 and the second transmission assembly 40 are used to jointly drive the mounting base 20 to rotate, so that the mounting base 20 can rotate smoothly.

[0056] Specifically, at least one of the two rotating wheels of each transmission component 40 is an active wheel. For example, the actuator includes two drive components 70, wherein one drive component 70 is used to drive a rotating wheel in the first transmission component 40 to rotate, and the other drive component 70 is used to drive a rotating wheel in the second transmission component 40 to rotate, so that the two transmission belts 42 can be used to simultaneously pull the mounting base 20 to rotate in a direction to overcome gravity or to limit the position of the mounting base 20, thereby avoiding a situation where the mounting base 20 cannot be pulled due to excessive mass.

[0057] In some embodiments of the present invention, the actuator also includes a limiting component, which is used to limit the rotation angle of the mounting base 20 so that the mounting base 20 rotates within an appropriate range, preventing the mounting base 20 from rotating at an excessive angle and causing the transmission belt 42 to be wrapped around the mounting base 20, thereby preventing the mounting base 20 from colliding with objects in the environment during rotation.

[0058] In some optional embodiments of the present invention, the base 10 is provided with a first stop portion, and the mounting seat 20 is provided with a second stop portion. The first stop portion and the second stop portion abut to limit the rotation angle of the mounting seat 20, thereby limiting the rotatable range of the mounting seat 20.

[0059] In some embodiments, a first stop portion is provided on the rotating shaft 23 of the mounting base 20, and a second stop portion is provided at the bottom of the base 10. When the mounting base 20 rotates in a clockwise direction, the first stop portion rotates toward the direction close to the bottom of the base 10. When the first stop portion and the second stop portion abut against each other, the mounting base 20 cannot continue to rotate in the clockwise direction, so as to limit the rotatable angle of the mounting base 20 in the clockwise direction, so that the mounting base 20 can rotate within a preset range, thereby preventing the mounting base 20 from rotating at too large an angle, causing the transmission belt 42 to be wrapped around the mounting base 20, and preventing the mounting base 20 from colliding with objects in the environment during rotation.

[0060] In some embodiments of the present invention, the actuator also includes a reset assembly, which is connected to the mounting seat 20 to apply a driving force to the mounting seat 20 to overcome the direction of gravity. In this way, when the rotating wheel rotates to drive the transmission belt 42 to move, and the transmission belt 42 drives the mounting seat 20 to rotate in the direction of overcoming gravity, the reset assembly and the transmission belt 42 can together provide a driving force for the rotation of the mounting seat 20 to overcome the gravity of the mounting seat 20. This makes it easy to reduce the load of the transmission assembly 40, weaken the influence of gravity on the operating stability of the transmission assembly 40, and enable the transmission assembly 40 to stably and reliably drive the mounting seat 20 to rotate.

[0061] In addition, when the rotating wheel rotates to drive the transmission belt 42 to move, the transmission belt 42 loosens the mounting seat 20, and the mounting seat 20 rotates in the direction of gravity under the action of gravity, the reset component can provide a buffering force for the rotation of the mounting seat 20, so that the mounting seat 20 can rotate stably and slowly in the direction of gravity, thereby reducing the rapid and abrupt rotation of the mounting seat 20 during the rotation process, thereby improving the safety of use and reducing the noise generated during use.

[0062] In some optional embodiments of the present invention, Figure 6 As shown, the mounting seat 20 is provided with a rotating shaft 23, and the rotating shaft 23 is rotatably provided on the base 10. The mounting seat 20 can rotate around the axis of the rotating shaft 23. The reset component includes a torsion spring 61, and the torsion spring 61 is sleeved on the rotating shaft 23 to apply a driving force to the mounting seat 20 in the direction of overcoming gravity. In this way, when the mounting seat 20 rotates in the direction of overcoming gravity, the torsion spring 61 and the transmission belt 42 can together provide a driving force for the rotation of the mounting seat 20, so as to overcome the gravity of the mounting seat 20 and enable the mounting seat 20 to rotate in the direction of overcoming gravity; when the mounting seat 20 rotates in the direction of gravity, the torsion spring 61 can provide a buffering force for the rotation of the mounting seat 20, so that the mounting seat 20 can rotate smoothly in the direction of gravity.

[0063] In some embodiments, Figure 5 , Figure 6 As shown, a mounting portion 231 is provided on the rotating shaft 23, and the mounting portion 231 is fixed to the rotating shaft 23. A mounting groove is provided on the mounting portion 231, and an extension direction of the mounting groove is perpendicular to the axial direction of the rotating shaft 23. A torsion spring 61 is sleeved on the rotating shaft 23, and one end of the torsion spring 61 is provided in the mounting groove and stops at the bottom wall of the mounting groove, and the other end of the torsion spring 61 stops at the base 10.

[0064] When the mounting seat 20 rotates downward in the clockwise direction, the mounting portion 231 rotates with the rotating shaft 23 and compresses the torsion spring 61, and the torsion spring 61 has a buffering force upward in the counterclockwise direction on the mounting seat 20 to buffer the downward rotation of the mounting seat 20. When the mounting seat 20 rotates upward in the counterclockwise direction, the torsion spring 61 can drive the mounting seat 20 to rotate upward together with the transmission belt 42.

[0065] In some embodiments of the utility model, the base 10 is provided with an opening, and the mounting seat 20 is rotatably provided in the opening. The mounting seat 20 has an expanded state and a stored state. When the mounting seat 20 is in the expanded state, the mounting seat 20 is rotated to be located below the opening. At this time, the mounting seat 20 leaks out of the opening so that the user can use the mounting seat 20 or use the components provided on the mounting seat 20. When the mounting seat 20 is in the stored state, at least a portion of the mounting seat 20 is accommodated in the opening to store the mounting seat 20, so as to prevent objects in the external environment from colliding with the mounting seat 20 and to prevent the user from hitting the mounting seat 20.

[0066] In some embodiments, the base 10 defines a storage cavity, and the opening is located below the storage cavity. When the mounting seat 20 or the components disposed on the mounting seat 20 need to be used, the mounting seat 20 can be rotated downward so that the mounting seat 20 leaks out of the storage cavity from the opening. When the mounting seat 20 is not needed or the components disposed on the mounting seat 20 are used, the mounting seat 20 can be rotated upward so that the mounting seat 20 enters the storage cavity from the opening or is located at the opening, so as to store the mounting seat 20, so that the base 10 can protect the mounting seat 20 and the components disposed on the mounting seat 20.

[0067] In some embodiments, a snap-fitting portion is provided on the base 10, and a snap-fitting portion is provided on one end of the mounting seat 20 away from its rotation axis 23. When the mounting seat 20 is rotated to the storage state, the snap-fitting portion cooperates with the snap-fitting portion to limit the position of the mounting seat 20 at this time.

[0068] In some embodiments of the present invention, Figure 1 , Figure 7 As shown, the mounting seat 20 is provided with a receiving groove for receiving the driven component, so as to protect the driven component and prevent the driven component from being scratched by foreign objects.

[0069] The mounting seat 20 may be a shell of the driven component, and no further restrictions are imposed here.

[0070] In some embodiments, the component to be driven may be a display screen, a microphone, a camera or a speaker, and no further restrictions are imposed herein.

[0071] In some embodiments, Figure 7 , Figure 8 As shown, the mounting base 20 includes an upper shell 251 and a lower shell 252, the upper shell 251 and the lower shell 252 jointly define a receiving groove, the driven member is a camera, the camera is fixed in the receiving groove, the receiving groove has an escape opening, the camera can shoot the outside world from the escape opening, the lower shell 252 has a rotating shaft 23, and the rotating shaft 23 is rotatably arranged on the base 10. When the transmission assembly 40 drives the mounting base 20 to rotate, the mounting base 20 drives the camera in the receiving groove to rotate, so as to adjust the shooting angle of the camera, thereby meeting the user's usage needs, wherein the camera can be used for taking pictures, photographing, gesture recognition or face recognition.

[0072] Specifically, when the mounting base 20 is rotated to the unfolded state, the mounting base 20 extends out of the storage cavity from the opening. At this time, the camera shell shoots the external environment from the avoidance opening. When it is necessary to take pictures with the camera, the shooting angle of the camera can be adjusted so that the camera can take pictures at a suitable angle. At the same time, it is convenient to use the camera for face recognition function.

[0073] When the mounting base 20 is rotated to the storage position, the mounting base 20 is rotated from the opening into the storage cavity, and the camera is stored at this time to prevent the camera from blocking the user's driving vision, affecting safe driving, and affecting the privacy and safety of passengers in the car. In addition, by storing the camera, the external environment and the camera are isolated, so that objects in the external environment are prevented from colliding with the camera and damaging the camera, and dust in the external environment is prevented from falling on the camera and affecting the camera's shooting.

[0074] What needs to be explained here is that the transfer into the storage chamber may be a part that rotates into the storage chamber and the other part that is at the opening, or both parts that are transferred into the storage chamber, and there is no excessive restriction here.

[0075] In some examples, the lower housing 252 defines a slot, the camera is disposed in the slot, and the sidewall of the slot can limit the horizontal movement of the camera. After the camera is disposed in the slot, the upper housing 251 is first snap-fitted and positioned with the lower housing 252, wherein the inner cavity of the upper housing 251 is provided with a rib plate, which is used to limit the upward movement of the camera. Then, a screw is passed through the screw column on the lower housing 252 and is threadedly fastened with the upper housing 251 to fix the upper housing 251 and the lower housing 252 together.

[0076] In some examples, such as Fig. 9 As shown, the mounting seat 20 also includes a connecting member 24, which is rotatably disposed on the upper shell 251, and one end of the transmission belt 42 is connected to the connecting member 24. When the transmission assembly 40 drives the mounting seat 20 to rotate, the connecting member 24 and the upper shell 251 rotate, so that the connecting member 24 always extends along the tension direction of the transmission belt 42. In this way, when the mounting seat 20 rotates, the extension direction of the end of the transmission belt 42 connected to the mounting seat 20 will not change, thereby ensuring the acting force between the transmission belt 42 and the mounting seat 20, facilitating the improvement of the transmission efficiency and transmission stability of the transmission belt 42 in transmitting force to the mounting seat 20, so that the transmission belt 42 can smoothly drive the mounting seat 20 to rotate.

[0077] Furthermore, a hinge support 27 is provided at the upper end of the upper shell 251 , and the connecting member 24 is rotatably provided on the hinge support 27 via a hinge, so that the connecting member 24 is rotatably provided on the upper shell 251 .

[0078] In some embodiments of the present invention, Figure 1 As shown, the actuator further includes a driving assembly 70, which is used to drive one of the rotating wheels to rotate, so that when the rotating wheel rotates, the transmission belt 42 can be driven to move, and then the transmission belt 42 can be used to drive the mounting seat 20 to rotate.

[0079] In some embodiments, the actuator also includes a reduction assembly, which is used to drive a gear in the reduction assembly to rotate, and another gear in the reduction gear is engaged with the rotating wheel to drive the rotating wheel to rotate. The reduction assembly is used to reduce the rotation speed transmitted to the rotating wheel by the drive assembly 70 and increase the rotation torque transmitted to the rotating wheel by the drive assembly 70, so that the rotating wheel can drive the transmission belt 42 to move when it rotates, and the transmission belt 42 can drive the mounting base 20 to rotate when it moves.

[0080] In other embodiments of the present invention, the actuator also includes a handle portion, which is used to drive one of the rotating wheels to rotate. The user can drive one of the rotating wheels to rotate by operating the handle portion. When the rotating wheel rotates, it can drive the transmission belt 42 to move, and then use the transmission belt 42 to drive the mounting base 20 to rotate.

[0081] In some embodiments of the present invention, Figure 2 , Figure 10-12 As shown, the actuator also includes a moving member 81, which is slidably disposed on the base 10, one end of the transmission belt 42 is connected to the mounting seat 20, and the other end of the transmission belt 42 is connected to the moving member 81. The transmission belt 42 can be tightened by using the moving member 81 and the mounting seat 20, so that the transmission belt 42 is in a tensioned state, and then the mounting seat 20 can be driven to rotate when the transmission belt 42 moves.

[0082] Among them, the actuator also includes a damping member 82, and the moving member 81 cooperates with the damping member 82. When the transmission assembly 40 drives the mounting seat 20 to rotate in the direction of gravity, the damping member 82 applies a damping force to the moving member 81 to slow down the moving speed of the transmission belt 42, so that the transmission belt 42 can drive the mounting seat 20 to move downward smoothly, thereby improving the safety of use and reducing the noise generated during use.

[0083] like Figure 1 As shown, in the present embodiment, the first connection end of the transmission belt 42 is connected to the moving member 81, and the second connection end of the transmission belt 42 is connected to the mounting seat 20. When the rotating wheel rotates in the clockwise direction, the first connection end of the transmission belt 42 moves to the left (it should be understood here that the above direction limitation is only for the convenience of describing the accompanying drawings, and will not limit the actual setting position and direction of the actuator). At this time, the second connection end of the transmission belt 42 releases the mounting seat 20, and the mounting seat 20 rotates downward under the action of gravity. When the first connection end of the transmission belt 42 moves to the left, the damping member 82 has a rightward force on the moving member 81 to buffer the leftward movement of the first connection end, so that the transmission belt 42 moves smoothly, avoiding the mounting seat 20 from rotating rapidly downward under the action of gravity, and avoiding breaking the transmission belt 42.

[0084] When the rotating wheel rotates counterclockwise, the second connection end of the transmission belt 42 pulls the mounting seat 20 to rotate upward, and the damping member 82 has a rightward driving force on the moving member 81. Driven by the damping member 82, the first end of the transmission belt 42 moves to the right to put the transmission belt 42 in a tensioned state. At the same time, a force can be applied to the transmission belt 42 to overcome the gravity of the mounting seat 20 together with the transmission belt 42, thereby reducing the load of the transmission assembly 40 and weakening the influence of gravity on the operating stability of the transmission assembly 40, so that the transmission assembly 40 can stably and reliably drive the mounting seat 20 to rotate.

[0085] In some optional embodiments of the present invention, Figure 10-12 As shown, one of the moving member 81 and the base 10 has a guide rail 13, and the other has a guide groove matching the guide rail 13 to limit the moving direction of the moving member 81, and then limit the moving direction of the other end of the transmission belt 42, so that the other end of the transmission belt 42 can move smoothly relative to the base 10.

[0086] like Fig.10 As shown, in this embodiment, the base 10 has a guide rail 13, and the moving member 81 has a guide groove. The guide rail 13 extends into the guide groove and slidably cooperates with the guide groove so that the moving member 81 can slide smoothly, and then the other end of the transmission belt 42 can move smoothly relative to the base 10.

[0087] In some embodiments, Figure 5 , Figure 10-12 The base 10 includes a base 101 and a fixed portion 102, the fixed portion 102 is fixed to the base 101, and the guide rail 13 is arranged on the fixed portion 102, wherein the fixed portion 102 defines a matching groove 103, one end of the damping member 82 stops at the left side wall of the matching groove 103, and the other end stops at the moving member 81, the guide rail 13 is arranged in the matching groove 103 and extends in the left and right directions, when the moving member 81 moves to the left, the damping member 82 is compressed and has a rightward force on the moving member 81.

[0088] Among them, a first mating protrusion 104 is provided on the right side wall of the mating groove 103, and a second mating protrusion 812 is provided on the left end of the moving member 81. The first mating protrusion 104 and the second mating protrusion 812 are located on the outer periphery of the damping member 82 so as to be able to limit the position of the damping member 82. Among them, when the moving member 81 moves to the left until the first mating protrusion 104 and the second mating protrusion 812 stop abutting against each other, the moving member 81 no longer continues to move to the left, so as to use the first mating protrusion 104 and the second mating protrusion 812 to limit the moving range of the moving member 81, thereby preventing the moving member 81 from being out of engagement with the fixed part 102.

[0089] In some optional embodiments of the present invention, Fig.11As shown, the damping member 82 is a spring member, which is respectively connected to the base 10 and the moving member 81 to apply a force to the moving member 81, so that when the transmission assembly 40 drives the mounting seat 20 to rotate in the direction of gravity, it can apply a damping force to the movement of the transmission belt 42, so as to slow down the movement speed of the transmission belt 42, so that the transmission belt 42 can drive the mounting seat 20 to move smoothly, thereby improving the safety of use and reducing the noise generated during use.

[0090] In addition, when the actuator vibrates, the spring element can absorb part of the vibration to achieve a buffering and shock-absorbing effect, thereby improving the rotation stability of the mounting seat 20.

[0091] In some embodiments, the damping member 82 is an elastic member to reserve a margin for the movement of the movable member 81, and further reserve a margin for the movement of the transmission belt 42 and the rotation of the mounting base 20. Specifically, when the mounting base 20 is rotated to the unfolded state and objects in the external environment collide with the mounting base 20, causing the mounting base 20 to rotate, the transmission belt 42 and the movable member 81 can move a certain distance so that the mounting base 20 can rotate a certain angle, so as to reduce the external force acting on the mounting base 20 and prevent the transmission belt 42 from being broken under the action of external force.

[0092] In some other optional embodiments of the present invention, the damping member 82 is hydraulic damping, damping gear, disc spring, friction plate damping, etc., and no excessive restrictions are made here.

[0093] In some specific embodiments of the present invention, Figure 1 , Figure 2 As shown, the driving assembly 70 includes a motor, which is used to drive the rotating wheel to rotate. When receiving an instruction to rotate the mounting seat 20 to the unfolded state, the motor rotates forward to drive the rotating wheel to rotate clockwise, and the rotating wheel drives the transmission belt 42 to move, and the transmission belt 42 drives the mounting seat 20 to rotate downward around its rotation axis 23. After the mounting seat 20 rotates to the specified position, the motor stops working to lock the mounting seat 20 at the specified position. In this process, the elastic member is compressed and has a damping effect on the movement of the transmission belt 42 to slow down the movement speed of the transmission belt 42.

[0094] When receiving the instruction to rotate the mounting base 20 to the storage state, the motor rotates in the reverse direction to drive the rotating wheel to rotate in the counterclockwise direction, the rotating wheel drives the transmission belt 42 to move, and the transmission belt 42 drives the mounting base 20 to rotate upward around its rotation axis 23. After the mounting base 20 is in the specified position, the motor stops working to lock the mounting base 20 at the specified position. In this process, the elastic member gradually extends to the initial position.

[0095] Among them, whether the mounting base 20 is in the specified position can be determined by the rotation angle of the motor, the position sensor, etc. The received instruction can be a key, a gesture, a voice or other perceptible behavior, and there are no excessive restrictions here.

[0096] In some embodiments of the utility model, the transmission belt 42 includes a flexible belt and a plurality of teeth, and the plurality of teeth are arranged at intervals along the length direction of the flexible belt. One end of the flexible belt is connected to the mounting seat 20, and the other end is connected to the movable member 81. The teeth are meshed with the rotating wheel. When the rotating wheel rotates, the rotating wheel has a driving force on the teeth, thereby driving the flexible belt to move back and forth, so that the flexible belt can drive the mounting seat 20 to rotate to adjust the angle of the mounting seat 20.

[0097] In some embodiments of the present invention, the transmission belt 42 may also be a synchronous belt, wherein the transmission ratio of the synchronous belt is constant, and the transmission accuracy and transmission efficiency are high. The transmission belt 42 may also be a wedge belt, a flat belt, a chain or a rope, and there is no excessive restriction here.

[0098] The multimedia device 1 according to the embodiment of the present invention is described below. The multimedia device 1 according to the embodiment of the present invention comprises the actuator according to the above embodiment of the present invention and a multimedia component 30 , which is disposed on the mounting base 20 to be driven to rotate by the mounting base 20 .

Specifically, the multimedia component 30 is the driven component described above. Of course, the driven component can also be other structures that need to be rotated, and there is no excessive restriction here.

[0100] The multimedia device 1 according to the embodiment of the utility model can adjust the angle of the multimedia component 30 relative to the user by utilizing the actuator according to the above-mentioned embodiment of the utility model, so as to adjust the multimedia component 30 to a better usage position, thereby facilitating the user to use the multimedia component 30, meeting the requirements of different users for the usage position, and improving the user's usage comfort.

[0101] In some embodiments of the present invention, Figure 4 , Figure 6 As shown, the mounting base 20 includes a supporting plate 26, the multimedia component 30 is a display screen, and the transmission assembly 40 is used to drive the supporting plate 26 to rotate. When the supporting plate 26 rotates, the supporting plate 26 drives the display screen to rotate to adjust the angle of the display screen, thereby facilitating improving the user's viewing angle.

[0102] In some embodiments, Figure 3 , Figure 6 As shown, a rotating shaft 23 is provided at one end of the carrier plate 26, and the rotating shaft 23 is rotatably provided on the base 10, and a connecting member 24 is provided on the other end of the carrier plate 26, and the connecting member 24 is rotatably provided on the carrier plate 26, and one end of the transmission belt 42 is connected to the connecting member 24 to drive the carrier plate 26 to rotate. Among them, the connecting member 24 is rotatably provided on the carrier plate 26, so that the connecting member 24 always extends along the tension direction of the transmission belt 42, so that when the mounting seat 20 rotates, the extension direction of the end of the transmission belt 42 connected to the carrier plate 26 will not change, thereby ensuring the acting force between the transmission belt 42 and the carrier plate 26, facilitating the improvement of the transmission efficiency and transmission stability of the transmission belt 42 in transmitting the force to the carrier plate 26, so that the transmission belt 42 can smoothly drive the carrier plate 26 to rotate.

[0103] Among them, when the mounting base 20 is rotated to the unfolded state, the mounting base 20 and the display screen extend out of the storage cavity from the opening. When the mounting base 20 is rotated to the storage position, the mounting base 20 and the display screen are transferred from the opening into the storage cavity. At this time, the display screen is stored to isolate the external environment and the display screen to prevent objects in the external environment from colliding with the display screen.

[0104] In some embodiments, Figure 3 As shown, a hinge support 27 is provided on the other end of the carrying plate 26 , and the connecting member 24 is rotatably provided on the hinge support 27 via a hinge, so that the connecting member 24 is rotatably provided on the carrying plate 26 .

[0105] In some embodiments, Figure 4 As shown, the supporting plate 26 has a supporting surface 261, and the display screen is fixed on the supporting surface 261. When the supporting plate 26 rotates, the supporting plate 26 drives the display screen to rotate so as to adjust the angle of the display screen relative to the user, thereby facilitating improving the viewing comfort of the user.

[0106] The carrying plate 26 may have two carrying surfaces 261 , which are arranged opposite to each other. Two display screens are respectively fixed on the carrying surfaces 261 to meet the viewing needs of users located on both sides of the carrying plate 26 .

[0107] In other embodiments, Figure 5As shown, the first end of the display screen is slidably disposed on the supporting plate 26, and the second end of the display screen is slidably disposed on the base 10, wherein when the supporting plate 26 rotates upward in a counterclockwise direction, the distance between the supporting plate 26 and the base 10 gradually decreases, at which point the first end of the display screen slides in a direction close to the rotation axis 23 of the supporting plate 26, and the second end of the display screen slides in a direction away from the rotation axis of the supporting plate 26, wherein when the mounting base 20 is in the storage position, the display screen extends in a horizontal direction, and at this point the supporting plate 26 can close the opening to protect the display screen and prevent objects in the external environment from colliding with the display screen through the opening.

[0108] When the supporting plate 26 rotates downward in the clockwise direction, under the action of gravity, the first end of the display screen slides in the direction away from the rotation axis of the supporting plate 26, and the second end of the display screen slides in the direction close to the rotation axis of the supporting plate 26, so that the display screen leaks out of the storage cavity, and the display screen can be used at this time.

[0109] When the carrying plate 26 is in the unfolded position, the display surface of the display screen faces away from the carrying plate 26 to prevent the carrying plate 26 from blocking the display surface.
