[0039] The main body 10 in this embodiment is the projector body, and its specific structure is prior art and will not be described in detail here.

[0040] refer to Figure 1 As shown, the body 10 and the speaker 11 in this embodiment are both arranged in the inner cavity of the shell assembly 12 , and the focus ring 101 on the lens of the body 10 is located at the opening side of the left side of the shell assembly 12 .

[0041] The above solution provided by the present application sets the body 10 and the speaker 11 in the same inner cavity of the shell assembly 12, making full use of the inner cavity space of the shell assembly 12, effectively reducing the overall volume, and facilitating carrying. Moreover, since the distance and angle of the support assembly 13 relative to the shell assembly 12 can be adjusted, when in use, by adjusting the corresponding distance and angle of the support assembly 13, it is possible to ensure that the projection angle of the body 10 meets the requirements, thereby bringing great convenience to people's use.

[0042] In some embodiments, Figure 1 Combined with Figure 2 As shown, the shell assembly 12 includes an upper shell 121, a lower shell 122 and a ventilation plate 123; wherein the upper shell 121 and the lower shell 122 are detachably connected, the ventilation plate 123 is arranged on the same side of the upper shell 121 and the lower shell 122, and the main body 10 and the speaker 11 are both arranged in an inner cavity surrounded by the upper shell 121 and the lower shell 122; the focusing ring 101 on the lens of the main body 10 is located on the side of the upper shell 121 away from the ventilation plate 123.

[0043] Exemplarily, the upper shell 121 and the lower shell 122 are detachably connected, and the ventilation plate 123 is arranged on the right side of the upper shell 121 and the lower shell 122. The upper shell 121, the lower shell 122 and the ventilation plate 123 are arranged to form a cylindrical structure with an opening on the left side.

[0044] In some embodiments, an opening slot 1211 is disposed at the upper shell 121 , and rotating teeth 102 are circumferentially disposed on the focusing ring 101 , and the rotating teeth 102 are located in the opening slot 1211 .

[0045] like Figure 3 As shown, since the rotating tooth 102 is located in the opening groove 1211 , a portion of the rotating tooth 102 is exposed to the external space, so that it is convenient to move the rotating tooth 102 to drive the focusing ring 101 .

[0046] In some embodiments, Figure 1 Combined with Figure 2 As shown, a through hole 1212 is provided on the upper shell 121 , and a USB interface 103 is provided on the body 10 ; when the body 10 is fixed to the inner cavity surrounded by the upper shell 121 and the lower shell 122 , the USB interface 103 is located in the through hole 1212 .

[0047] The USB interface 103 in this embodiment is electrically connected to the body 10 . When the body 10 is fixed to the inner cavity enclosed by the upper shell 121 and the lower shell 122 , the USB interface 103 is located in the through hole 1212 , so it is convenient to insert an external USB flash drive into the USB interface 103 .

[0048] In some embodiments, Figure 2 As shown, a connecting piece 1213 is provided at the side of the upper shell 121 facing the lower shell 122, and a plug hole 1221 is provided at the side plate of the lower shell 122 facing the upper shell 121; when the upper shell 121 and the lower shell 122 are connected, the connecting piece 1213 is inserted into the plug hole 1221. In this way, it is convenient to quickly connect the upper shell 121 and the lower shell 122 together.

[0049] Of course, it is understandable that the upper shell 121 and the lower shell 122 can also be connected by bolts, which can be determined according to actual conditions and is not limited in this embodiment of the present specification.

[0050] In some embodiments, Figure 2 As shown, the ventilation plate 123 is provided with ventilation holes 1231. In this way, the heat dissipation of the body 10 is facilitated to prevent the temperature of the inner cavity surrounded by the upper shell 121 and the lower shell 122 from being too high.

[0051] In some embodiments, Figure 2As shown, a connecting hole 1232 is provided on the ventilation plate 123, and a fixing block 104 is provided on the main body 10, and the fixing block 104 can move axially along the main body 10; when the main body 10 is fixed to the inner cavity enclosed by the upper shell 121 and the lower shell 122, the fixing block 104 is located in the connecting hole 1232.

[0052] In this embodiment, the right sides of the upper shell 121 and the lower shell 122 are correspondingly provided with card slots, and the ventilation plate 123 is carded into the card slots on the right sides of the upper shell 121 and the lower shell 122.

[0053] During installation, first snap the ventilation plate 123 onto the right side of the lower shell 122 , and then fix the main body 10 in the lower shell 122 . At this time, the fixing block 104 is located in the connecting hole 1232 , thereby preventing the main body 10 from shaking. Finally, install the upper shell 121 onto the lower shell 122 .

[0054] refer to Figure 2 As shown, since the fixing block 104 can move axially along the body 10 , that is, the fixing block 104 can move in the left and right directions, when disassembly is required, it is only necessary to press the fixing block 104 by external force to disengage the fixing block 104 from the connecting hole 1232 .

[0055] Furthermore, the fixing block 104 in this embodiment is connected to the body 10 via an elastic member.

[0056] Specifically, the elastic member is a compression spring, which is arranged on the body 10 in the left-right direction, one end of the compression spring is fixed on the body 10, and the other end is connected to the fixing block 104. In this way, the fixing block 104 can be moved in the left-right direction by pressing the fixing block 104 with external force.

[0057] In some embodiments, Figure 1 As shown, the support assembly 13 includes a base 131, a lifting rod 132 and a rotating member 133, wherein the rotating member 133 is arranged between the upper shell 121 and the lower shell 122, one end of the lifting rod 132 is connected to the rotating member 133, and the other end is connected to the base 131, and the angle of the lifting rod 132 relative to the rotating member 133 is adjustable.

[0058] In this embodiment, the lifting rod 132 may be an electric telescopic rod, etc., which may be specifically determined according to actual conditions, and the embodiments of this specification do not limit this.

[0059] The rotating member 133 can be a universal joint, a stepper motor, etc., which can be determined according to actual conditions, and the embodiments of this specification do not limit this. One end of the lifting rod 132 is connected to the universal joint, or to the output shaft of the stepper motor, and the other end is threadedly connected to the base 131. In this way, the height of the entire projector can be easily adjusted through the lifting rod 132, and the projection angle of the body 10 can be easily adjusted by adjusting the angle between the lifting rod 132 and the rotating member 133, which greatly facilitates people's use.

[0060] In some embodiments, a metal weight plate is disposed on the bottom surface of the base 131. In this way, the metal weight plate can ensure the stability of the projector and facilitate the projector to be fixed on the wall or ceiling.

[0061] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the application concept of the present application, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present application.
