[0049] An embodiment of the present utility model provides a manually liftable screen intelligent speaker. Referring to Figure 1 , it includes:

[0050] A speaker main body 1;

[0051] A display screen 2, accommodated in the speaker main body 1;

[0052] A lifting component 3, used to drive the display screen 2 to perform lifting movement. The lifting component 3 is installed on the speaker main body 1, and the display screen 2 is connected to the driving end of the lifting component 3;

[0053] A rotating component 4, used to drive the display screen 2 to rotate to achieve the switching of usage states. The usage states of the display screen 2 include a first state and a second state; the rotating component 4 is connected between the display screen 2 and the driving end of the lifting component 3.

[0054] The present embodiment improves the installation structure of the existing speaker display screen 2, and a lifting component 3 and a rotating component 4 are arranged between the display screen 2 and the speaker body 1, wherein the lifting component 3 can control the display screen 2 to be lifted and lowered to meet the customer's requirements for using the display screen 2 at different heights, and the rotating component 4 can drive the display screen 2 to switch between the first state and the second state, and change the angle of the display screen 2 to meet the user's requirements for using it at different angles, thereby adapting to different usage scenarios and meeting the diverse needs of users. Specifically, the speaker body 1 is provided with a storage slot for accommodating the display screen 2. When the display screen 2 is not in use, the display screen 2 is stored in the speaker body 1. When the display screen 2 needs to be used, the user can drive the lifting component 3 to perform lifting movement, thereby driving the display screen 2 to extend from the storage slot; when the angle of the display screen 2 needs to be changed, the user can drive the rotating component 4 to perform rotational movement, thereby driving the display screen 2 to rotate to achieve angle change. The first state and the second state described in this embodiment are the corresponding two angles during the rotation process of the display screen 2. It can be understood that the rotating component 4 can drive the display screen 2 to rotate 360° freely, and the first state and the second state can be set according to actual needs. When the display screen is in the horizontal state, it is convenient for users to watch videos, and when the display screen is in the vertical state, it is convenient for users to broadcast live; in this embodiment, reference Figure 2 , Figure 3 and Figure 4 , the first state of the display screen 2 is the horizontal screen state. At this time, the rotating component 4 is located at the edge of the display screen, and the display screen 2 can be directly flipped open for user use. The structure is simple and the operation is convenient. Further, the display screen 2 can be switched to the second state based on the first state, wherein the second state includes when the rotating component 4 is located at the edge of the display screen 2, the display screen is switched to the vertical screen, and when the rotating component 4 is located at the center of the display screen 2, the display screen 2 switches between the horizontal screen and the vertical screen. It should be noted that in the above-mentioned second state, the vertical screen state when the rotating component 4 is located at the edge of the display screen 2 can be achieved by directly driving the display screen to rotate 90° on the basis of the first state. The structure is simple and the switching is convenient; when the rotating component 4 is located at the center of the display screen 2 to switch between the horizontal screen and the vertical screen, it is necessary to drive the rotating component 4 to move to the center of the display screen 2 through the driving mechanism and then drive the display screen 2 to rotate to switch between the horizontal screen and the vertical screen. In this way, the rotating component is located at the center of the display screen 2, so that the force point of the display screen 2 is located at its center, which can ensure that the rotation process of the display screen 2 is more stable.

[0055] Further, the rotating assembly 4 includes a universal ball assembly 41. In this embodiment, the universal ball assembly 41 includes a universal ball head 411, a universal ball groove 412 for accommodating the universal ball head 411, and a damping member that plays a certain damping role in the rotation of the universal ball head 411 in the universal ball groove 412. The damping member is not limited here, and it can increase the friction force during the rotation of the universal ball head 411, so as to play a certain damping role in the rotation of the universal ball head 411 to position the rotation angle of the screen. Specifically, in this embodiment, the damping member can be set as an elastic plastic part wrapped on the surface of the universal ball head 411, etc. In this embodiment, the universal ball assembly 41 can be integrally installed on the back of the display screen 2, or integrally installed on the lifting assembly 3. Alternatively, the universal ball groove 412 and the universal ball head 411 are respectively arranged on the back of the display screen 2 or the lifting assembly 3, and its installation position is not limited here. In this embodiment, setting the rotating assembly 4 as the universal ball assembly 41 can meet the 360° rotation of the display screen 2 with multiple degrees of freedom to meet the multi-angle use requirements of users.

[0056] Further, the lifting screen speaker further includes a sliding assembly. The sliding assembly is connected to the display screen 2. The sliding assembly is used to drive the display screen 2 to slide in the first direction, and the rotating assembly 4 is connected to the sliding assembly. In this embodiment, a sliding assembly is added to the back of the display screen 2, and the rotating assembly 4 is connected to the sliding assembly. When the rotating assembly 4 drives the display screen 2 to switch states, the structural stability of the display screen 2 and the viewing comfort of the user can be ensured.

[0057] Specifically, in this embodiment, referring to Figure 2 、 Figure 3 and Figure 4 , the sliding assembly is arranged along the central axis of the display screen 2 and is consistent with the width direction of the display screen 2. The first end of the sliding stroke of the sliding assembly is located at the edge of the display screen 2, and the second end is located at the central position of the display screen 2; in the initial state of the display screen 2, the rotating assembly 4 is located at the central position of one of the longer sides of the display screen 2, which is convenient for the storage of the display screen 2. When the display screen 2 needs to be lifted, the lifting assembly 3 drives the display screen 2 to rise. As shown in Figure 2 , at this time, the rotating member is still located at the first end of the sliding stroke. At this time, if the display screen 2 is driven by the rotating assembly 4 to rotate to the vertical screen state, the display screen 2 rotates directly around the center point of its edge without the need for sliding operation by the sliding assembly, and the switching speed of the display screen is faster; further, in this embodiment, the second end of the sliding assembly is arranged at the central position of the display screen 2. Before the display screen 2 rotates, the sliding assembly is first slid to the second end, as shown in Figure 3 , at this time, when rotating again, the display screen 2 rotates around its center, with strong stability. After rotating to the vertical screen state, as shown in Figure 4As shown, the lifting component 3 bisects the entire display screen 2, with strong stability and a better viewing experience.

[0058] Furthermore, the sliding component includes at least one slide rail 51. The slide rail 51 is connected to the display screen 2, and a sliding connection member 52 that slides along the length direction of the slide rail 51 is installed on the slide rail 51. The rotating component 4 is connected to the sliding connection member 52. In this embodiment, the sliding component adopts an existing slide rail 51 guiding structure, which can ensure the stability of the sliding process of the sliding component. The sliding connection member 52 can be set as a slider adapted to the slide rail 51. According to the actual structural requirements, connection structures such as connection blocks can be installed on the slider for connection with the rotating component 4. The structure is simple, the cost is low, and the operation is stable.

[0059] Furthermore, the sliding component further includes at least one sliding limiting member, which is used to limit the position of the sliding connection member 52 on the slide rail 51. It should be noted that in order to ensure that the sliding component can stably maintain its current position after sliding to the target position, a sliding limiting member can be added to limit the sliding connection member 52, so as to adjust the sliding position of the display screen 2 and ensure its stability.

[0060] Furthermore, referring to Figure 5 , the slide rails 51 are provided in two, and the two slide rails 51 are arranged in parallel, which can further improve the stability of the sliding process. And the two slide rails 51 are respectively slidably connected to a sliding connection member 52, and a rotating shaft 54 is connected between the two sliding connection members 52. The rotating component 4 is connected to the rotating shaft 54. In this embodiment, the sliding connection members 52 are set as two sliders respectively adapted for sliding connection, and the two sliders are connected by a rotating shaft 54. The rotating component 4 is connected to this rotating shaft 54. In this embodiment, the rotating component 4 can adopt the above-mentioned universal ball component 41. In this embodiment, by connecting a rotating shaft 54 between the two sliders, while ensuring the structural stability, the display screen 2 can also be driven to rotate by a certain angle. Cooperating with the universal ball component 41, the switching of the usage state of the display screen 2 can be completed.

[0061] Furthermore, referring to Figure 6 , in this embodiment, the sliding limiting member includes a tape measure 531. The tape measure 531 is arranged along the length direction of the slide rail 51. One end of the tape measure 531 is connected to the end of the slide rail 51, and the other end of the tape measure 531 is connected to a winding and unwinding mechanism 532. The winding and unwinding mechanism 532 is used to wind or unwind the tape measure 531, and the winding and unwinding mechanism 532 is installed on the sliding connection member 52.

[0062] In this embodiment, the sliding stopper is configured to be similar to the structure of the tape measure 531 in the prior art, wherein one end of the tape measure 531 is connected to the end of the slide rail 51, and this end is the fixed end, while the other end of the tape measure 531 is connected to the reeling and unreeling mechanism 532 for reeling and unreeling. The reeling and unreeling mechanism 532 is installed on the sliding connection member 52 and will slide along the slide rail 51 with the sliding connection member 52. Therefore, when the sliding connection member 52 slides close to the fixed end of the tape measure 531, the reeling and unreeling mechanism 532 reels, and when the sliding connection member 52 slides away from the fixed end of the tape measure 531, the reeling and unreeling mechanism 532 unreels, thereby realizing the sliding of the display screen 2. In this embodiment, the two sliding connections 52 are also connected by a rotating shaft 54, and the rotating assembly 4 is connected to the rotating shaft 54, wherein the rotating assembly 4 is configured as a universal ball assembly 41, and the rotating shaft 54 ​​is provided with a universal ball groove 412, and the universal ball head 411 is provided at the driving end of the lifting assembly 3.

[0063] Further, in this embodiment, reference Figure 8 The sliding assembly is also provided with a first limiting mechanism for limiting the winding and unwinding of the measuring tape 531, and the first limiting mechanism includes a plurality of slots 511 provided along the length direction of the slide rail 51, and an elastic clamping platform 521 provided on the sliding connection member 52 and clamped with the plurality of slots 511. In this embodiment, through the elastic clamping between the slots 511 and the elastic clamping platform 521, during the winding and unwinding process of the measuring tape 531, that is, during the sliding process of the sliding connection member 52 along the slide rail 51, elastic damping is provided to the sliding of the measuring tape 531, so as to limit the sliding process, facilitate the positioning of the sliding position, and meet the different requirements of users for the sliding position of the sliding assembly.

[0064] Furthermore, in the present embodiment, the measuring tape 431 and the reeling and winding mechanism 532 can be obtained by using the measuring tape commonly used in the prior art. The existing standard measuring tape has a limit structure, and the reeling and winding of the measuring tape can be limited to different positions by pushing the switch. This structure does not require structural modifications to the slide rail 51 and the sliding connector 52, has lower costs, and is more convenient to use.

[0065] Further, refer to Figure 7 The lifting screen speaker box also includes a sliding mounting shell 6, the sliding component is installed in the sliding mounting shell 6, and the sliding mounting shell 6 can be detachably mounted on the display screen 2.

[0066] In this embodiment, a sliding mounting shell 6 is added and the entire sliding assembly is installed in the sliding mounting shell 6, and the sliding mounting shell 6 is detachably connected to the display screen 2. In this way, a detachable connection between the sliding assembly and the display screen 2 is achieved, and the sliding assembly can be installed and disassembled as a whole, which makes the operation more convenient. The sliding assembly can be replaced or replaced with other structures according to actual usage requirements.

[0067] Furthermore, a first limiting strip 61 and a second limiting strip 62 are arranged in the sliding mounting shell 6 along the sliding direction of the sliding connecting piece 52. The first limiting strip 61 abuts against the sliding rail 51, and the second limiting strip 62 abuts against the sliding connecting piece 52. In this embodiment, the first limiting strip 61 and the second limiting strip 62 provide a limiting and guiding groove along the sliding direction of the sliding assembly. During the sliding process of the sliding assembly, the sliding connecting piece 52 can slide in the groove formed by the first limiting strip 61 and the second limiting strip 62, effectively guiding its sliding process and preventing derailment. At the same time, the overall structure is more stable and the sliding is smoother and more stable.

[0068] Furthermore, a fixing plate 63 is also installed in the sliding mounting shell 6. The fixing plate 63 is connected to the end of the sliding rail 51, and the fixing plate 63 is connected to the ends of the first limiting strip 61 and the second limiting strip 62. In this embodiment, by adding a fixing plate 63, it can be avoided that the sliding connecting piece 52 slides out of the sliding rail 51, effectively limiting the sliding stroke of the sliding assembly. At the same time, the sliding assembly is enclosed in the sliding mounting shell 6 for protection.

[0069] Furthermore, referring to Figure 9 , the rotating assembly 4 includes a support rod 42. One end of the support rod 42 is hinged to the driving end of the lifting assembly 3, and the other end of the support rod 42 is connected to the display screen 2 through a universal ball assembly 41. In this embodiment, the structure of the rotating assembly 4 is changed. Among them, a receiving groove for receiving the support rod 42 can be formed on the back of the display screen 2. One end of the support rod 42 is connected to the center of the display screen 2 through the universal ball assembly 41, and the other end of the support rod 42 can be hinged to the driving end of the lifting assembly 3 through a rotating shaft 421. In this way, during use, through the rotating shaft 421, the whole display screen 2 can be driven to be parallel, perpendicular or form an angle with the speaker body 1, so as to realize the storage and unfolding of the display screen 2. Through the universal ball assembly 41, the angle of the display screen 2 can be adjusted, so as to realize the switching between the first state and the second state, that is, the switching between the horizontal screen and the vertical screen.

[0070] Furthermore, referring to Figure 10, the rotating assembly 4 includes a turntable 43. One side of the turntable 43 is hinged to the driving end of the lifting assembly 3, and the other side of the turntable 43 is detachably connected to the display screen 2. In this embodiment, another implementation structure of the rotating assembly 4 is provided. Wherein, one end of the turntable 43 is connected to the center of the back of the display screen 2, so that the display screen 2 can rotate 360° around the turntable 43, thereby realizing the switching between the first state and the second state, that is, the switching between landscape and portrait. And the other end of the turntable 43 is hinged to the driving end of the lifting assembly 3 through a rotating shaft 421. Similarly, in use, through the rotating shaft 421, the whole display screen 2 can be driven to be parallel, perpendicular or form an angle with the speaker main body 1, so as to realize the storage and deployment of the display screen 2. In this embodiment, the turntable 43 can be detachably connected to the display screen 2 by magnetic attraction or suction cup.

[0071] Furthermore, the lifting assembly 3 is set as at least one telescopic rod structure.

Wherein, a second limiting mechanism is arranged between the fixed rod 31 and the lifting rod 32 to limit the lifting position of the display screen 2. The second limiting mechanism can adopt a conventional limiting structure in the prior art, such as the structure of elastic protrusions and card holes, referring to Figure 11 , a card hole 33 is opened at the top of both the fixed rod 31 and the lifting rod 32. A first spring 35 is installed coaxially inside the fixed rod 31 and the lifting rod 32, and an elastic protrusion 34 is connected to the top of the first spring 35. The first spring 35 will always push the elastic protrusion 34 tightly against the top of the lifting rod 32 through its elastic force. When the lifting rod 32 shrinks in the fixed rod 31, the card holes 33 of the two correspond, and the elastic protrusion 34 is inserted into the card holes of the lifting rod 32 and the fixed rod 31 in sequence to lock the lifting rod 32; when the lifting rod 32 needs to be raised, just pull the lifting rod 32 forcefully or press the elastic protrusion 34 by hand, and the elastic protrusion 34 can be contracted, so as to unlock the lifting rod 32 to facilitate the lifting of the lifting rod 32. At this time, the first spring 35 will push up the lifting rod 32 to support it, and the lifting of the lifting rod 32 is completed. Among them, the elastic protrusion 34 can abut against the second spring 36 to realize its elastic expansion and contraction.
