DETAILED DESCRIPTION

[0025] The specific embodiments of the present application will be described in more detail below in conjunction with the drawings and examples, so that the advantages of the scheme of the present application and its various aspects can be better understood. However, the specific embodiments and examples described below are for illustrative purposes only, not as a limitation of the present application.

[0026] Referring to the drawings Figures 1-8 As shown in the drawings, in this embodiment, a multifunctional projection speaker with sound and light functions includes a box 1 with a hollow cavity, at least one loudspeaker 3, a projector 2, and a supporting telescopic rod 4. The sound playing function of the loudspeaker 3 and the projection function of the projector 2 are used to realize the sound and light functions of the box.

[0027] In the embodiment, the box 1 is provided with a projection cavity 11 opening upward and communicating with the hollow cavity, and at least one horn hole 12 opening sideways and communicating with the hollow cavity. The projection cavity 11 is a mounting position of the projector 2, the projector 2 is movably arranged in the projection cavity 11, and is used for projecting an optical image outward. The horn hole 12 is a mounting position of the loudspeaker 3, the loudspeaker 3 is built-in mounted at the horn hole 12, and is used for outputting sound.

[0028] In the embodiment, the support telescopic rod 4 is built-in mounted in the hollow cavity, and a telescopic end of the support telescopic rod 4 is connected with a bottom of the projector 2 movably arranged in the projection cavity 11. With the telescopic action of the support telescopic rod 4, the projector 2 is moved upward and out of the projection cavity 11 or moved downward and embedded in the projection cavity 11, that is, the projector 2 is projected out of the projection cavity 11 or stored in the projection cavity 11.

[0029] In the embodiment, when the force is applied to the support telescopic rod 4 in the contraction state, the support telescopic rod 4 is correspondingly switched under pressure between the preset unlocking state and the locking state. When the projector 2 is embedded in the projection cavity 11, the projector 2 is pressed to apply the force to the support telescopic rod 4 in the contraction state, so that the support telescopic rod 4 is switched to the unlocking state and is automatically extended to drive the projector 2 to move upward and out of the projection cavity 11. Conversely, when the projector 2 needs to be stored, the projector 2 is pressed to drive the support telescopic rod 4 to gradually contract until the support telescopic rod 4 is about to be contracted to the position, and then the force is further applied to the support telescopic rod 4, so that the support telescopic rod 4 is switched to the locking state. At this time, the telescopic end of the support telescopic rod 4 is limited and cannot be extended, and correspondingly, the projector 2 is moved downward and embedded in the projection cavity 11.

[0030] In the embodiment, the support telescopic rod 4 comprises a cylinder 41, a piston rod 42 slidingly installed in the inner cavity of the cylinder 41, a self-locking guide sleeve 43 coaxially movably sleeved in the inner cavity of the cylinder 41, and a self-locking top sleeve 44 coaxially fixedly sleeved on the piston rod 42. The cylinder 41 provides an internal space for the operation of other components as the main structure of the entire telescopic rod. The piston rod 42 is used to adjust the telescopic length of the support telescopic rod 4 as a rod sliding in the inner cavity of the cylinder 41. The self-locking guide sleeve 43 is a component coaxially movably sleeved in the inner cavity of the cylinder 41, and the inner circumferential surface thereof is designed with at least two annularly arranged locking blocks 431 and at least four annularly arranged guide rotating blocks 432 to realize the self-locking function. Specifically, the locking blocks 431 are block-shaped structures annularly arranged on the inner circumferential surface of the self-locking guide sleeve 43, and each locking block 431 has a downwardly open limiting groove 4311 which can be oppositely stopped and cooperated with the top block 441 on the self-locking top sleeve 44 to realize the locking function. The guide rotating blocks 432 are block-shaped structures annularly arranged on the inner circumferential surface of the self-locking guide sleeve 43, located below the locking blocks 431, and each guide rotating block 432 has a guide inclined surface 4321. The self-locking top sleeve 44 is a cylindrical component coaxially fixedly sleeved on the piston rod 42, and the outer circumferential surface thereof is designed with a plurality of top blocks 441 which have top pressing inclined surfaces 4411 and can be top-touch cooperated with the guide rotating blocks 432 on the self-locking guide sleeve 43.

[0031] Further, the locking blocks 431 are located above the guide rotating blocks 432, and each locking block 431 is circumferentially partially overlapped with two guide rotating blocks 432 at the same time, and the top-touch between the top pressing inclined surfaces 4411 and the guide inclined surfaces 4321 promotes the axial movement of the self-locking top sleeve 44 to be converted into the self-rotation action of the self-locking guide sleeve 43. In this way, with the self-rotation of the self-locking guide sleeve 43, the locking blocks 431 rotate to avoid or align with the top blocks 441. When the locking blocks 431 align with the top blocks 441, the support telescopic rod 4 is correspondingly switched to the locked state, and vice versa. For the convenience of understanding, the following will be further explained in combination with the specific working mode.

[0032] In the embodiment, the support telescopic rod is arranged vertically, and the fixed end of the support telescopic rod 4 is fixedly connected to the bottom surface of the hollow cavity. The support telescopic rod 4 adopts a pneumatic telescopic rod or a gas spring structure. In addition to the cylinder 41, the piston rod 42, the self-locking guide sleeve 43, and the self-locking top sleeve 44 listed above, the cylinder 41 is internally provided with a chamber in which compressed gas is arranged, and the lower end of the piston rod 42 is correspondingly provided with a piston arranged inside the cylinder 41, and the upper end of the piston rod 42 is correspondingly extended outside the cylinder 41 as a telescopic end of the support telescopic rod 4. Therefore, the elasticity of the spring is realized by using the compressibility of the gas. The structure and principle between the cylinder and the piston are conventional technical means, and will not be described in detail.

[0033] When the piston rod 42 slides in the cylinder 41, the top block 441 moves axially correspondingly with the piston rod 42. When it is needed to lower the projector 2 to embed into the projection cavity 11, the user applies a downward force to the projector 2, so that the piston rod 42 moves downward correspondingly to the contraction state, and the top block 441 moves to be close to the guide rotating block 432 of the self-locking guide sleeve 43 (at this time, the top block 441 has avoided passing over the lock block 431), and then further applying a force to the projector 2 (equivalent to the piston rod 42) will further drive the top block 441 to continuously move downward, so that the top pressing slope 4411 of the top block 441 is in top touch cooperation with the guide slope 4321 of the guide rotating block 432, thereby driving the self-locking guide sleeve 43 to rotate, and then the lock block 431 rotates with the self-locking guide sleeve 43 and switches to align with the top block 441. At this time, the user stops applying force, and the piston rod 42 extends outward by the gas spring action of the support telescopic rod 4, so that the top block 441 moves axially upward with the piston rod 42 and is clamped into the limiting groove 4311 of the lock block 431, and the self-locking action is completed. Correspondingly, the support telescopic rod 4 is switched to the locked state. Conversely, when it is needed to move the projector 2 upward to extend out of the projection cavity 11, the user applies a downward force to the projector 2, so that the piston rod 42 moves downward correspondingly, the top block 441 moves downward to exit the limiting groove 4311 of the lock block 431 and moves close to the guide rotating block 432 of the self-locking guide sleeve 43, so that the top pressing slope 4411 of the top block 441 is in top touch cooperation with the guide slope 4321 of the guide rotating block 432, thereby driving the self-locking guide sleeve 43 to rotate, and then the lock block 431 rotates with the self-locking guide sleeve 43 and switches to avoid the top block 441. At this time, the user stops applying force, and the piston rod 42 extends outward by the gas spring action of the support telescopic rod 4, and at the same time, the top block 441 moves axially upward with the piston rod 42 and passes over the lock block 431, and is no longer limited. The piston rod 42 can smoothly extend and drive the projector 2 to complete the upward movement.

[0034] In the embodiment, in order to make the top block 441 smoothly move down and pass the lock block 431, the top of the lock block 431 is shaped with an avoiding slope 4312 which can top touch the top pressing slope 4411 of the top block 441, and the top pressing slope 4411 and the avoiding slope 4312 top touch each other to promote the self-rotation of the lock guide sleeve 43, so that the top block 441 can rotate to avoid the top block 441, avoiding the interference of the top block 441 passing the lock block 431.

[0035] In the embodiment, the connecting assembly 5 is arranged between the supporting telescopic rod 4 and the projector 2, wherein the connecting assembly 5 comprises a fixing seat 51 for fixedly connecting with the telescopic end of the supporting telescopic rod 4, and a turnover seat 52 for fixedly connecting with the bottom of the projector 2, the turnover seat 52 is pivotally connected to the fixing seat 51 around a horizontal axis to make the projector 2 pivot around the horizontal axis relative to the box body 1 to make upward or downward action, further increasing the flexibility of use.

[0036] In summary, the loudspeaker 3 and the projector 2 are integrated in the same box body 1, realizing the dual functions of audio playing and image projection, saving space and improving the use convenience, meanwhile, the projector 2 can be moved out or embedded in the projection cavity 11, making the overall structure compact and the appearance beautiful.

In addition, under the guidance of the present application, the features and embodiments can be modified to adapt to specific conditions and materials without departing from the spirit and scope of the present application.
