[0058] An embodiment of the present utility model provides an electric lift screen smart speaker. Referring to Figure 1 , it includes:

[0059] A speaker main body 1;

[0060] A display screen 2, accommodated in the speaker main body 1;

[0061] An electric lift assembly 3, used to drive the display screen 2 to lift, and the electric lift assembly 3 is installed on the speaker main body 1;

[0062] A rotation assembly, used to drive the display screen 2 to switch states, the rotation assembly is connected to the driving end of the electric lift assembly 3, and the driving end of the rotation assembly is connected to the display screen 2.

[0063] This embodiment improves the installation structure of the existing speaker display screen 2. An electric lift assembly 3 and a rotation assembly are provided between the display screen 2 and the speaker main body 1. Among them, the electric lift assembly 3 can automatically control the display screen 2 to lift to meet the user's usage requirements for different heights of the display screen 2, while the rotation assembly can drive the display screen 2 to rotate at multiple angles to meet the user's usage requirements for different angles of the display screen 2. Thus, the speaker can adapt to different usage scenarios and meet the diverse needs of users. Specifically, the speaker main body 1 is provided with a storage slot for accommodating the display screen 2. When the display screen 2 is in the unused state, the display screen 2 is stored in the speaker main body 1. When the display screen 2 needs to be used, the electric lift assembly 3 drives the display screen 2 to extend out of the storage slot; when the angle of the display screen 2 needs to be changed, the user can drive the rotation assembly to perform a rotational movement, thereby driving the display screen 2 to rotate to achieve an angle change to meet the user's usage requirements for different heights and different angles of the display screen 2.

[0064] Furthermore, referring to Figure 2, the electric lifting assembly 3 includes a lifting drive motor 31, the drive end of the lifting drive motor 31 is connected to a screw rod 32, the screw rod 32 meshes with a lifting limiter 33 that slides along its length direction, and the lifting limiter 33 is connected to the rotating assembly.

[0065] In this embodiment, when the electric lifting assembly 3 drives the display screen 2 to lift, the lifting drive motor 31 is started, and the lifting drive motor 31 will drive the screw rod 32 to rotate. The lifting limiter 33 meshes with the screw rod 32 through a threaded structure. Therefore, during the forward or reverse rotation of the screw rod 32, as Figure 11 shown, the lifting limiter 33 will lift along the length direction of the screw rod 32. Connect the lifting limiter 33 to the rotating assembly, and the rotating assembly is connected to the display screen 2. Thus, the display screen 2 can be driven to lift by the lifting limiter 33 to meet the user's different height usage requirements for the display screen 2. Further, in this embodiment, the lifting limiter 33 is connected to the display screen 2 or the rotating assembly through a push rod 37. During the lifting process of the lifting limiter 33, the push rod 37 is pushed out or retracted from the electric lifting assembly 3 to realize the lifting drive of the display screen 2.

[0066] Further, the electric lifting assembly 3 further includes at least one guide rail 34 arranged in parallel with the screw rod 32. A sliding member 35 is slidably mounted on the guide rail 34, and the sliding member 35 is connected to the lifting limiter 33.

[0067] In this embodiment, to ensure the stability of the sliding of the lifting limiter 33, a guide rail 34 is added to guide its movement. Among them, a sliding member 35 is slidably connected to the guide rail 34, and the sliding member 35 can slide along the length direction of the guide rail 34. Connect the lifting limiter 33 to the sliding member 35 to realize the sliding connection between the lifting limiter 33 and the guide rail 34 and ensure the stability of the sliding process of the lifting limiter 33. In this embodiment, the sliding member 35 can adopt a slider that is slidably adapted to the guide rail 34 in the prior art to ensure the stability of the sliding process.

[0068] Further, limiting plates 36 for limiting the sliding of the sliding member 35 are respectively installed at both ends of the guide rail 34. It should be noted that in this embodiment, the limiting plates 36 are respectively arranged at both ends of the guide rail 34, which can effectively limit the movement of the lifting limiter 33, thereby controlling the lifting range of the display screen 2, avoiding the detachment or impact between the lifting limiter 33 and the screw rod 32, and ensuring the stability of the structure.

[0069] Further, referring to Figure 12, in this embodiment, the electric lifting component 3 is further provided with a housing 38. At this time, the electric lifting component 3 is an independent and detachable whole and is housed in the housing 38 to meet the requirements of various applicable scenarios. For example, when not in use, it can be housed in the speaker main body 1 or can be separately housed as an independent component in other areas. When in need of use, referring to Figure 13 and Figure 14 , it can be inserted into the first insertion port 11 of the speaker main body 1. Plug-in terminals electrically connected to the lifting drive motor 31 of the electric lifting component 3 can be provided in the first insertion port 11 to achieve the plug-and-play of the electric lifting component 3. Then, the display screen 2 is installed at its drive end, and the lifting control of the display screen 2 can be realized. At the same time, by providing the housing 38, the internal components of the electric lifting component 3 can be effectively protected, and its service life can be improved.

[0070] Furthermore, referring to Figure 13 , in this embodiment, a second insertion interface 12 can be opened in the speaker main body 1. The second insertion interface 12 is provided at the bottom of the speaker main body 1. The electric lifting component 3 is inserted into the second insertion interface 12. Through the lifting of the electric lifting component 3, the lifting control of the speaker main body 1 can be realized to meet the diverse needs of users. At the same time, plug-in terminals electrically connected to the lifting drive motor 31 of the electric lifting component 3 can be provided in the second insertion interface 12 to achieve the plug-and-play of the electric lifting component 3.

[0071] Embodiment 1

[0072] In this embodiment, the rotating component includes:

[0073] A first electric rotating component for driving the display screen 2 to rotate to realize the switching of the usage states. The usage states of the display screen 2 include a first state and a second state;

[0074] A second electric rotating component for driving the display screen 2 to rotate to realize the switching of the usage states. The usage states of the display screen 2 include a third state and a fourth state.

[0075] In this embodiment, a first electric rotating component and a second electric rotating component are provided between the speaker main body 1 and the display screen 2 for automatically controlling the state switching of the display screen 2 to meet the diverse needs of users and adapt to the requirements of different usage environments.

[0076] Among them, the first electric rotating component can control the display screen 2 to switch between the first state and the second state. Among them, when the display screen 2 is in the first state, referring to Figure 5 , the display screen 2 is parallel to the surface of the speaker main body 1, and the display screen 2 can be housed in the groove on the surface of the speaker main body 1; when the display screen 2 is in the second state, referring to Figure 6, the first electric rotating component drives the display screen 2 to unfold, and the display screen 2 automatically opens from the surface of the speaker body 1 for the user to use.

[0077] The second electric rotating component can control the display screen 2 to switch between the third state and the fourth state. Among them, when the display screen 2 is in the third state, the display screen 2 is still in the unfolded state, and the display screen 2 is in the landscape screen state at this time; when the display screen 2 is in the fourth state, refer to Figure 7 , the second electric rotating component drives the display screen 2 to rotate 90°, so that the display screen 2 is switched from the landscape screen state to the portrait screen state for the customer to use.

[0078] Specifically, refer to Figure 3 , the first electric rotating component includes a first driving motor 41, the driving end of the first driving motor 41 is connected to a first rotating shaft 42, and the first rotating shaft 42 is connected to the display screen 2 to drive the display screen 2 to rotate. The first state of the display screen 2 is that the display screen 2 is parallel to the surface of the speaker body 1, and the second state of the display screen 2 is that the display screen 2 is perpendicular to the surface of the speaker body 1. In this embodiment, the first rotating shaft 42 is connected to the display screen 2. When it is necessary to control the display screen 2 to switch between the first state and the second state, only the first driving motor 41 needs to drive the first rotating shaft 42 to rotate, and the first rotating shaft 42 drives the display screen 2 to rotate to complete the unfolding and closing of the display screen 2.

[0079] Further, the second electric rotating component includes a second driving motor 51, the driving end of the second driving motor 51 is connected to an electric universal ball head 52, and the electric universal ball head 52 is connected to the display screen 2 to drive the display screen 2 to rotate. The third state of the display screen 2 is that the display screen 2 is set in the landscape screen, and the fourth state of the display screen 2 is that the display screen 2 is set in the portrait screen. In this embodiment, the second driving motor 51 can be connected to the push rod 37 of the electric lifting component 3, and the electric universal ball head 52 is connected to the display screen 2. When it is necessary to control the display screen 2 to switch between the third state and the fourth state, only the second driving motor 51 needs to drive the electric universal ball head 52 to rotate, and the display screen 2 can be driven to rotate between the landscape screen state and the portrait screen state to realize the switching between the landscape screen and the portrait screen.

[0080] Further, the rotating assembly further includes a third electric translation assembly for moving along the axis of the display screen 2, and both the first electric rotating assembly and the second electric rotating assembly are connected to the driving end of the third electric translation assembly. It should be noted that in the above embodiments, the rotation of the display screen 2 is performed around one side of the display screen 2, and the stability of the display screen 2 is poor. Therefore, in this embodiment, a third electric translation assembly is added. After the first electric rotating assembly and the second electric rotating assembly are controlled by the third electric translation assembly to move to the centroid position on the back of the display screen 2 and then rotate, the stability of the rotation process of the display screen 2 can be improved.

[0081] Specifically, referring to Figure 3 and Figure 4 , the third electric translation assembly includes a third driving motor 61, at least one driving gear 62 is connected to the driving end of the third driving motor 61, a rack 63 meshing with the driving gear 62 is installed on the display screen 2, and a guide member 64 for installing the gear is further included. The guide member 64 is slidably connected to the rack 63; both the first electric rotating assembly and the second electric rotating assembly are connected to the guide member 64.

[0082] In this embodiment, the third driving motor 61 drives the driving gear 62 to rotate. Since the driving gear 62 meshes with the rack 63, it will move along the rack 63 in the length direction of the rack 63, thereby driving the guide member 64 to slide along the direction of the rack 63. Both the first electric rotating assembly and the second electric rotating assembly are connected to the guide member 64, so that they can move together with the guide member 64 in the length direction of the rack 63. To ensure the stability of the structural operation, in this embodiment, the rack 63 is provided with two symmetrical ones. Correspondingly, one gear is meshed on each rack 63, and the driving end of the third driving motor 61 can coaxially connect the two gears through a shaft, so as to drive the two gears to rotate synchronously.

[0083] Further, the rack 63 is provided with a first end and a second end for limiting the sliding stroke of the guide member 64. The first end is located on one side of the display screen 2, and the second end is located at the center of the display screen 2. In this embodiment, the displacement of the gear is limited by the rack 63, so as to drive the first electric rotating assembly and the second electric rotating assembly to reciprocate between the edge and the centroid of the display screen 2.

Alternatively, the universal ball groove 712 and the universal ball head 711 are respectively provided on the back of the display screen 2 or the driving end of the electric lifting assembly 3, and its installation position is not limited herein. In this embodiment, setting the rotating assembly as the universal ball assembly 71 can meet the 360° rotation of the display screen 2 with multiple degrees of freedom to meet the multi-angle usage requirements of users.

[0086] Further, the rotating assembly further includes a manual sliding assembly. The manual sliding assembly is connected to the display screen 2 and is used to drive the display screen 2 to slide in a first direction. The universal ball assembly 71 is connected to the driving end of the manual sliding assembly. In this embodiment, by adding a manual sliding assembly to the back of the display screen 2 and connecting the rotating assembly to the manual sliding assembly, the structural stability of the display screen 2 and the viewing comfort of the user can be ensured when the rotating assembly drives the display screen 2 to switch states.

[0087] Specifically, referring to Figure 8 , the manual sliding assembly includes at least one slide rail 81. The slide rail 81 is connected to the display screen 2, and a sliding connection member 82 that slides along the length direction of the slide rail 81 is installed on the slide rail 81. The universal ball assembly 71 is connected to the sliding connection member 82. The manual sliding assembly further includes at least one sliding limit member for limiting the position of the sliding connection member 82 on the slide rail 81. In this embodiment, the sliding assembly adopts an existing slide rail 81 guiding structure, which can ensure the stability of the sliding process of the sliding assembly. The sliding connection member 82 can be set as a slider adapted to the slide rail 81. According to the actual structural requirements, connection structures such as connection blocks can be installed on the slider for connection with the rotating assembly. The structure is simple, the cost is low, and the operation is stable.

[0088] Further, referring to Figure 9, the sliding rails 81 are provided in two, the two sliding rails 81 are arranged in parallel, and the two sliding rails 81 are respectively slidably connected to a sliding connector 82. A second rotating shaft 85 is connected between the two sliding connectors 82, and the universal ball assembly 71 is connected to the second rotating shaft 85; in this embodiment, the sliding connector 82 is provided as two sliders respectively adapted for sliding connection, and the two sliders are connected by a second rotating shaft 85. The rotating assembly is connected to the second rotating shaft 85. In this embodiment, the rotating assembly can adopt the above-mentioned universal ball assembly 71. In this embodiment, by connecting a second rotating shaft 85 between the two sliders, while ensuring the structural stability, the display screen 2 can also be driven to rotate at a certain angle. Cooperating with the universal ball assembly 71, the switching of the usage state of the display screen 2 can be completed.

[0089] Reference Figure 8 , the sliding limiting member includes a measuring tape 83, the measuring tape 83 is arranged along the length direction of the sliding rail 81, one end of the measuring tape 83 is connected to the end of the sliding rail 81, the other end of the measuring tape 83 is connected to a winding and unwinding mechanism 84, and the winding and unwinding mechanism 84 is used for winding or unwinding the measuring tape 83. The winding and unwinding mechanism 84 is installed on the sliding connector 82, and a first limiting mechanism for limiting the winding and unwinding of the measuring tape 83 is installed on the winding and unwinding mechanism 84.

[0090] In this embodiment, the sliding limiting member is set to a structure similar to the measuring tape 83 in the prior art. Among them, one end of the measuring tape 83 is connected to the end of the sliding rail 81, and this end is the fixed end, while the other end of the measuring tape 83 is connected to the winding and unwinding mechanism 84 for winding and unwinding. The winding and unwinding mechanism 84 is installed on the sliding connector 82 and will slide along the sliding rail 81 with the sliding connector 82. Therefore, when the sliding connector 82 slides close to the fixed end of the measuring tape 83, the winding and unwinding mechanism 84 winds, and when the sliding connector 82 slides away from the fixed end of the measuring tape 83, the winding and unwinding mechanism 84 unwinds, so as to realize the sliding of the display screen 2. In this embodiment, the two sliding connectors 82 are also connected by a second rotating shaft 85, and the rotating assembly is connected to the second rotating shaft 85. Among them, the rotating assembly is set to a universal ball assembly 71, and the second rotating shaft 85 is provided with a universal ball groove 712, and the universal ball head 711 is arranged at the driving end of the lifting assembly.

[0092] In this embodiment, by adding a sliding mounting shell 91, the manual sliding assembly is entirely installed inside the sliding mounting shell 91, and the sliding mounting shell 91 is detachably connected to the display screen 2. In this way, the detachable connection between the manual sliding assembly and the display screen 2 is realized, and the whole manual sliding assembly can be installed and disassembled, which is more convenient to operate. According to actual usage requirements, the manual sliding assembly can be replaced or substituted with other structures.

[0093] Furthermore, a first limiting strip 92 and a second limiting strip 93 are arranged inside the sliding mounting shell 91 along the sliding direction of the sliding connector 82.
