[0032] Reference Figures 1 to 6 The portable projector of this utility model is described in the following embodiment:

[0033] In some embodiments, refer to Figure 1 and 2 A portable projector includes a projection component 100 and a first support 110 on both sides of the projection component 100. An illumination component 200 has two second supports 280 respectively corresponding to the first supports 110. The second supports 280 and the first supports 110 are connected by a damping hinge assembly 300. The illumination component 200 can rotate relative to the projection component 100 to obtain a suitable illumination angle. The damping hinge assembly 300 combines the projection and illumination components, making it easier to adjust the projector angle without loosening after multiple adjustments, resulting in a better feel.

[0034] Reference Figure 3 As shown in the figure, the structure of the damping shaft assembly 300 and its related support frame 214 is described in detail in this embodiment.

[0035] The first bracket 110 is designed in an L-shape, specifically including a first connecting piece and a second connecting piece that are interconnected. The first connecting piece is connected to the projection assembly 100, ensuring the stability of the projection assembly 100. The second connecting piece has a first connecting hole for subsequent assembly connection. The second bracket 280 is in the form of a connecting plate, which has a second connecting hole for easy fixed connection with the first bracket 110 or other components. The damping shaft assembly 300 includes a first friction plate 310, a second friction plate 320, a connecting shaft 330, and an anti-loosening nut 340. The connecting shaft 330 is designed in the form of a screw, with its head serving as the abutment part, i.e., the nut part of the screw, a design that facilitates rotation operation by the user.

[0036] Both the first friction plate 310 and the second friction plate 320 are made of rubber washers or other materials with frictional properties. The connecting shaft 330 passes sequentially through the second bracket 280, the first friction plate 310, the first bracket 110 (through the first connecting hole on the second connecting plate), and the second friction plate 320, and is finally threadedly connected to the anti-loosening nut 340, thereby tightly pressing and fixing all components. When the abutting part (i.e., the nut) of the connecting shaft 330 is located outside the projection assembly 100, the user can adjust the contact pressure between the friction plate and the support frame 214 by rotating the connecting shaft 330. During this process, sliding friction will be formed between the first bracket 110 and the first friction plate 310, between the first friction plate 310 and the second bracket 280 (through the contact at the second connecting hole on the connecting plate), and between the second bracket 280 and the second friction plate 320. By adjusting this friction, the user can easily adjust the resistance of the damping shaft assembly 300 to achieve fine-tuning of the angle of the projection assembly 100 or stable positioning. This adjustment structure is not only simple and intuitive, but also extremely convenient to operate.

[0037] Reference Figure 2 The lighting assembly 200 includes a connecting frame 210, a light source 220, a connector 230, a light guide column 240, a lampshade 250, and a bottom cover 260. The connecting frame 210 includes a base 213 and a support frame 214. The base 213 has two connecting arms, which are respectively connected to two second brackets 280. The light source 220 includes a light-emitting panel and a power supply board 221. The light-emitting panel is ring-shaped and is located on the base 213. The connector 230 is cylindrical and is located on the base 213. The light guide column 240 has a hollow structure and is sleeved on the outside of the connector 230. The connecting frame 210 includes a circular sleeve, and two support arms are connected to both ends of the circular sleeve. The two support arms are connected to... The connecting arm is correspondingly set and fastened to the outside of the connecting arm, which can serve to cover the connecting shaft 330, making the lighting component 200 more aesthetically pleasing. The cross-section of the two supporting arms is arc-shaped. There are two lampshades 250, which are two arc-shaped transparent plates. The lampshades 250 are set between the two supporting arms. The two lampshades 250 and the two supporting arms form a cylindrical structure. One end of the cylindrical structure is the base 213, and the other end is the bottom cover 260. One end of the bottom cover 260 is provided with a rubber ring. At the same time, the light source 220 and the bottom cover 260 are respectively set at both ends of the light guide post 240. A counterweight 290 is fixed inside the connector 230. The counterweight 290 is fixed to the connector 230 by multiple screws.

[0038] Reference Figure 4The lighting assembly 200 also includes a piano-style button 270. Pressing the piano-style button 270 controls the brightness of the lighting assembly 200 and the on / off state of the lighting switch. For a more aesthetically pleasing design, the piano-style button 270 is fitted into the end of the connecting frame 210. The piano-style button 270 slides along the extension direction of the connecting frame 210 at the end of the connecting frame 210. For multiple control methods, two piano-style buttons 270 are provided. In some other embodiments, one or three piano-style buttons 270 may be provided.

[0039] Reference Figure 5 and Figure 6 The connecting bracket 210 is equipped with a limiting part to prevent the piano-style button 270 from dislodging. The limiting part is a limiting rod 211. The piano-style button 270 is equipped with a snap-fit ​​block, which is a snap-fit ​​271. The limiting rod 211 is located on the outer side of the piano-style button 270. When the piano-style button 270 is pressed, the side of the pressed piano-style button 270 slides relative to the limiting rod 211. An elastic element, generally a return spring or elastic sheet, is provided between the piano-style button 270 and the base 213. When the piano-style button 270 is pressed, the elastic element plays a reset role. Due to the snap-fit ​​271, it plays a limiting role, preventing the piano-style button 270 from dislodging from the base 213. As can be seen from the figure, the width of the snap-fit ​​271 is less than the length of the arc-shaped connecting rod, so that the snap-fit ​​271 does not need to be precisely aligned with the arc-shaped connecting rod, only a rough alignment is required, which facilitates installation and reduces the precision requirements of the piano-style button 270. In some other embodiments, the limiting part is a positioning block, and the piano-style button 270 is provided with a snap-fit ​​step. The positioning block and the snap-fit ​​step work together to achieve the limiting function.

[0040] The piano-style button 270 is provided with a cantilever 272. The end of the cantilever 272 is located next to the circuit board of the light source 220. When the piano-style button 270 is pressed, the hanging end of the cantilever 272 will come into contact with the circuit board inside the light source 220.

[0041] To ensure that the range of motion of the cantilever 272 is effectively controlled, a stop 212 is installed on the connecting frame 210, and this end of the cantilever 272 is positioned between the light source 220 and the stop 212.

[0042] To further optimize the pressing effect, the cantilever 272 is designed with a guide hole 2721 at one end, while the stop block 212 is equipped with a corresponding guide post 2121. When the piano button 270 is pressed, the cantilever 272 moves accordingly, and the guide hole 2721 on it slides smoothly along the guide post 2121 of the stop block 212 until the other end of the cantilever 272 contacts the circuit board contact of the light source 220. When the pressure is released, that is, when the piano button 270 is released, the button and the cantilever 272 can quickly return to their original position due to the elastic element.

[0043] The design of the guide post 2121 and the guide hole 2721 not only limits the tendency of the cantilever 272 to translate during the pressing process, but also significantly improves the stability of the structure, making the piano button 270 more precise and sensitive to operate.

[0044] In terms of layout, the piano-style buttons 270 are typically positioned at the edge of the connecting bracket 210 for easy pressing by the user. In specific application scenarios or design requirements, the buttons can also be flexibly adjusted to the center of the base 213.

[0045] In some other embodiments, a common push button may also be used, with a return spring at the bottom, so that the lighting can be turned on or off by pressing the switch.

[0046] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
