Detailed implementation manners

[0043] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0044] It should be noted that when a component is referred to as "fixed" or "set" or "connected" to another component, it can be directly or indirectly located on that other component. The orientations or positions indicated by terms such as "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientations or positions shown in the drawings, and are only for convenience of description and should not be construed as a limitation on the technical solution of the present invention. Terms such as "first", "second", etc. are only for convenience of description purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of technical features. The meaning of "plural" is two or more, unless otherwise specifically defined. The meaning of "several" is one or more, unless otherwise specifically defined.

[0045] As Figure 1 、 Figure 3 、 Figure 4 and Figure 6 shown, in an embodiment of the present utility model, a portable multi-functional projector includes a lighting device 1. A receiving cavity is provided in the center of the lighting device 1, and a projector body 2 is placed in the receiving cavity. An opening is provided at the top of the lighting device 1, and the opening is directly opposite to the lens of the projector body 2 for the projection light to be emitted.

[0046] After the projector is started, the projector body 2 processes the light emitted by the light source through an internal optical system, such as color correction and brightness adjustment, and projects it onto the projection lens. The lens of the projector is directly opposite to the opening at the top of the lighting device 1 to ensure that the projection light can be emitted unobstructed and project the image or video content onto the screen. At the same time, the user can adjust the lighting brightness, lighting color, lighting effect, etc. of the lighting device 1 through buttons, remote controls or mobile phone APPs according to personal preferences or environmental needs to create a comfortable viewing atmosphere and improve the viewing experience.

[0047] By providing a receiving cavity on the lighting device 1 and organically combining the projector body 2 with the lighting device 1, the structure of this projector is compact and its volume is small. It not only integrates diversified functions but also is convenient to carry and store. Whether it is for home entertainment, business presentations or outdoor camping, it can be easily carried and used.

[0048] In a preferred example, the projector body 2 is an LCD projector.

[0049] LCD projectors use liquid crystal display technology to project images onto a screen. The structure includes a liquid crystal panel, a light source, and a lens system. The light source generates strong light, which, after processes such as filtering and lens focusing, is evenly irradiated onto the liquid crystal panel. The liquid crystal panel consists of transparent electrodes and a liquid crystal layer. When an electric current passes through, the liquid crystal molecules rearrange, changing their optical properties, thereby controlling the passage or blocking of light. This process occurs in the form of a pixel grid, with each pixel independently controlled by liquid crystal molecules to form an image. In LCD projectors, usually three liquid crystal panels are used to display the three primary colors of red, green, and blue respectively, and through the synthesis of light, a full-color image is finally projected.

[0050] LCD projectors have high color accuracy and rich color performance, and can truly reproduce the color details in images, making them suitable for displaying pictures and videos with rich colors. Secondly, the brightness of LCD projectors is usually high, and they can maintain a good projection effect in a relatively bright environment, meeting the needs of various usage scenarios. At the same time, with mature technology and relatively low manufacturing costs, the market price of LCD projectors is relatively affordable and suitable for the general consumers.

[0051] As Figure 3 、 Figure 4 、 Figure 6 and Figure 7 shown, in a preferred example, the lighting device 1 includes a lamp holder 101, a lampshade 102 is provided at the top of the lamp holder 101, a top cover 103 is provided at the top of the lampshade 102, a first receiving groove 104 for placing the light source 105 is provided on the lamp holder 101, a second receiving groove 106 for placing the projector body 2 is provided on the lamp holder 101, and the lampshade 102 and the top cover 103 surround the outside of the projector body 2.

[0052] The first receiving groove 104 is an annular groove 113, and the light source 105 is annular.

[0053] The light source 105 is an LED.

[0054] In this embodiment, by setting the light source 105 to be annular and placing it in the first receiving groove 104 of the lamp holder 101, and at the same time setting the second receiving groove 106 to accommodate the LCD projector body 2, the internal space is fully utilized to achieve an organic integration of the lighting and projection functions. The lampshade 102 and the top cover 103 surround the projector body 2, which not only protects the projector but also enhances the overall compactness and aesthetics, making the entire device more portable and suitable for use in various scenarios. By using an LED as the light source 105, the LED has advantages such as high efficiency, long life, and low energy consumption. Its annular design can provide a more uniform and wider illumination range, helping to improve the overall brightness of the lighting device 1, reducing light spots and shadows, and making the lighting effect more natural.

[0055] AsFigure 4 As shown, in a preferred example, a controller 107 is provided on the lamp shade 102, and the controller 107 is used to control the light source 105 to emit light.

[0056] Specifically, the controller 107 is a touch switch. The controller 107 includes a first switch portion for controlling the on / off of the light source 105, a second switch portion for controlling the brightness of the light source 105, and a third switch portion for controlling the color of the light source 105.

[0057] In this embodiment, by setting the touch switch as the controller 107, the user can control the lighting state, brightness, and color of the light source 105 through touch operations, which is convenient for operation and improves the convenience of use. The touch switch is beautiful and generous, in line with the operation trend of modern smart homes, bringing a more comfortable and smooth user experience to the user. The first switch portion, the second switch portion, and the third switch portion on the controller 107 are respectively responsible for controlling the on / off, brightness, and color of the light source 105, enabling the user to make fine adjustments according to their own needs. Whether it is necessary to adjust the brightness to adapt to different ambient light, or to change the color of the light source 105 to create a specific atmosphere, the user can easily achieve it, thus enhancing the flexibility and personalization of the adjustment of the light source 105. At the same time, integrating the touch switch controller 107 on the lamp shade 102 makes the entire lighting device 1 look more integrated and beautiful.

[0058] As Figure 4 and Figure 7 shown, in a preferred example, a connecting rod 201 is provided at the bottom of the projector body 2, a connecting hole 108 is provided on the lamp holder 101, the connecting rod 201 is inserted into the connecting hole 108, and a screw threadedly connected to the connecting hole 108 is provided through the connecting hole 108.

[0059] In this embodiment, by providing the connecting rod 201 at the bottom of the projector body 2 and correspondingly opening the connecting hole 108 on the lamp holder 101, a stable connection between the two is achieved, which can improve the assembly efficiency during the installation process. The stability between the connecting rod 201 and the connecting hole 108 is also ensured by the screw, guaranteeing the stability of the projector and the clarity of the projection effect, bringing a more reliable and comfortable viewing experience to the user.

[0060] As Figure 6 and Figure 7 shown, in a preferred example, heat dissipation holes 202 and connector holes 203 are provided at the bottom of the projector body 2, and through holes 109 are provided on the lamp holder 101, and the through holes 109 correspond to the positions of the heat dissipation holes 202 and the connector holes 203.

[0061] In this embodiment, by providing through holes 109 in the lamp holder 101 corresponding to the heat dissipation holes 202 and connector holes 203 on the projector body 2, efficient heat dissipation and convenient external connection functions are achieved. The setting of the heat dissipation holes 202 ensures good heat dissipation performance of the projector during long-term operation, avoiding performance degradation or equipment damage caused by overheating. At the same time, the corresponding design of the connector holes 203 and the through holes 109 provides users with flexible external interfaces, facilitating the connection of various external devices or data transmission, further expanding the usage scenarios and functions of the projector. The through holes 109 on the lamp holder 101 ensure that the projector body 2 can dissipate heat normally and connect external devices.

[0062] As Figure 3 and Figure 6 shown, in a preferred example, the top cover 103 is rotatably connected to the lamp cover 102. The inner wall of the top cover 103 is provided with gear teeth 110, and the top of the lamp cover 102 is provided with a pivot 111. A gear 112 is sleeved on the pivot 111, and the gear 112 meshes with both the gear teeth 110 and the focus adjustment ring 204 of the projector body 2. The relative rotation of the top cover 103 and the lamp cover 102 is used to adjust the focal length of the projector body 2.

[0063] A ring groove 113 is provided at the top of the outer side of the lamp cover 102, and a first buckle 114 is provided on the inner wall of the top cover 103. The first buckle 114 is engaged in the ring groove 113.

[0064] During use, the user adjusts the focal length by rotating the top cover 103. As the top cover 103 rotates, the gear 112 will rotate accordingly, thereby driving the focus adjustment ring 204 to rotate, enabling the user to conveniently adjust the focal length of the projector by rotating the top cover 103.

[0065] In this embodiment, the focal length adjustment is achieved through the meshing of the top cover 103, the gear 112, and the focus adjustment ring 204. The top cover 103, as a component of the lighting device 1, also has the function of adjusting the focal length, making the overall exterior of the projector neat and unified, enhancing the aesthetics. At the same time, the engagement of the first buckle 114 on the inner wall of the top cover 103 and the ring groove 113 at the top of the outer side of the lamp cover 102 ensures the stability and reliability of the top cover 103 during rotation.

[0066] As Figure 6 and Figure 7 shown, in a preferred example, a card slot 116 is provided at the bottom of the outer side of the lamp cover 102, and a second buckle 115 is provided on the lamp holder 101 for engaging with the second buckle 115.

[0067] In this embodiment, the lamp shade 102 and the lamp base 101 are snap-connected through the second snap 115 and the slot 116, which is convenient for installation and enhances the connection reliability between the lamp shade 102 and the lamp base 101. At the same time, the tight combination of the second snap 115 and the slot 116 also effectively prevents external impurities such as dust and water vapor from entering the device, plays a good protective role for the electrical components and optical systems of the projector, and extends the service life of the device.

[0068] As Figure 2 and Figure 5 shown, in a preferred example, a support base 3 is provided at the bottom of the lamp base 101, and the support base 3 is rotatably connected to the lamp base 101.

[0069] A first connecting column 117 is provided at the bottom of the lamp base 101, a second connecting column 301 is provided at the top of the support base 3, a rotating shaft 118 is provided between the first connecting column 117 and the second connecting column 301, and the first connecting column 117 and the second connecting column 301 are rotatably connected through the rotating shaft 118. A damping member 4 is sleeved outside the rotating shaft 118, and the damping member 4 is used to limit the relative rotation of the first connecting column 117 and the second connecting column 301.

[0070] During use, the user adjusts the angles of the first connecting column 117 and the second connecting column 301 to adjust the angles of the lamp shade 102 and the projector body 2. When the user applies an appropriate force, the first connecting column 117 and the second connecting column 301 rotate around the rotating shaft 118, thereby driving the entire lamp shade 102 and the projector body 2 to change angles. At the same time, since a damping member 4 is sleeved outside the rotating shaft 118, the rotation process is not an unrestricted free rotation, but is effectively restricted by the damping member 4. The user needs to continuously apply a certain force to overcome the damping force and make the lamp shade 102 and the projector body 2 continue to rotate to the desired angle. When the appropriate angle is reached, the user stops applying force. Due to the action of the damping member 4, the lamp shade 102 and the projector body 2 will hover at this angle and no longer continue to rotate.

[0071] In this embodiment, by providing the rotating shaft 118 and the damping member 4, the flexible adjustment and stable hovering of the angles of the lamp shade 102 and the projector body 2 are realized, providing a more convenient and personalized user experience for the user, and also ensuring the stability and safety of the device during use. The damping member 4 enables the device to stably maintain at the angle set by the user, ensuring the clarity and stability of the projection screen.

[0072] As Figure 5As shown, in a preferred example, the damping member 4 includes a limiting sleeve 401 sleeved on the rotating shaft 118. Along the axial direction on the outer side of the limiting sleeve 401, there is a fixed limiting strip 402. On the second connecting column 301, there is a limiting groove 302 engaged with the fixed limiting strip 402. At the first end of the limiting sleeve 401, there are movable engaging teeth 403. On the first connecting column 117, there is a tooth groove 119 engaged with the movable engaging teeth 403. A spring 404 is also sleeved on the rotating shaft 118. The first end of the spring 404 abuts against the second end of the limiting sleeve 401, and the second end of the spring 404 abuts against the first connecting column 117.

[0073] When the user needs to adjust the angle between the lamp housing 102 and the projector body 2, an external force is applied to relatively rotate the first connecting column 117 and the second connecting column 301. Since the fixed limiting strip 402 of the limiting sleeve 401 is engaged with the limiting groove 302 on the second connecting column 301, the limiting sleeve 401 on the rotating shaft 118 is driven to rotate. In addition, the movable engaging teeth 403 in the limiting sleeve 401 are dynamically engaged with the tooth groove 119 on the first connecting column 117, increasing the resistance of rotation. When the movable engaging teeth 403 are opposite to the teeth in the tooth groove 119, the spring 404 is compressed. When the movable engaging teeth 403 are engaged with the groove in the tooth groove 119, the spring 404 extends. When the external force disappears, the elastic force of the spring 404 causes the movable engaging teeth 403 and the tooth groove 119 to be engaged, thus realizing the stable hovering of the lamp housing 102 and the projector body 2.

[0074] In this embodiment, through the mechanical cooperation of the fixed limiting strip 402, the limiting groove 302, the movable engaging teeth 403, and the tooth groove 119, as well as the elastic restoring force of the spring 404, a reliable damping system is jointly formed. This system can effectively limit the degree of freedom of rotation, prevent excessive rotation, and also provide stable support at the angle required by the user.

[0075] As Figure 1 and Figure 4 shown, in a preferred example, in the projection in the vertical direction, the projected area of the support base 3 is equivalent to the projected area of the lamp base 101. An eccentric counterweight 303 is provided inside the support base 3, and the counterweight 303 biases towards the direction of rotation of the first connecting column 117.

[0076] In this embodiment, by eccentrically arranging the counterweight 303 inside the support base 3 and making it bias towards the direction of rotation of the first connecting column 117, the stability of the device is improved. Due to the effect of the counterweight 303, the device can maintain a relatively low center-of-mass offset when rotating and adjusting the angle, thereby reducing the risk of tipping due to angle changes. In addition, the projected areas of the lamp base 101 and the support base 3 in the vertical direction are equivalent, making the appearance of the device coordinated and beautiful.

[0077] As Figure 3 and Figure 4As shown, in a preferred example, the support base 3 is connected to a power cord, and the power cord is electrically connected to the projector body 2 and the light source 105 through wires. A power switch 304 is provided on the wire, and the power switch 304 is located at the top of the support base 3. Wiring holes for wire routing are provided on the first connecting column 117 and the second connecting column 301.

[0078] In this embodiment, through a reasonable layout design of the power cord and wires, a convenient connection between the projector body 2, the light source 105 and the power supply is achieved, and the safety and neatness of the circuit are ensured. The power switch 304 is arranged at the top of the support base 3, which is convenient for users to control the power on and off of the device at any time, improving the convenience of use. At the same time, the wiring holes provided on the first connecting column 117 and the second connecting column 301 provide an orderly wire routing path for the wires, avoiding potential safety hazards and messy appearance caused by exposed wires, and maintaining the overall beauty and practicality of the device.

[0079] In a preferred example, a battery is provided inside the support base 3, and the battery is electrically connected to the light source 105.

[0080] In this embodiment, by providing a battery inside the support base 3 and electrically connecting it to the light source 105, convenient wireless power supply is provided for the projector device, getting rid of the bondage of traditional power cords, making the device more flexible and free during movement and use, and enhancing the independence and portability of the device.

[0081] In a preferred example, a speaker is provided inside the support base 3, and the speaker is electrically connected to the conductive projector.

[0082] In this embodiment, by integrating a speaker system inside the support base 3 and electrically connecting it to the projector, the sound quality effect during movie viewing or presentation can be improved without connecting external speaker devices.

[0083] In a preferred example, a connecting part is provided on the support base 3, and the connecting part is used to fix the support base 3.

[0084] Specifically, the connecting part is a hook.

[0085] Or the connecting part is a magnet.

[0086] Or the connecting part is a hanging hole.

[0087] In this embodiment, a hook is used as the connecting part, which can conveniently hang the support base 3 on a wall, ceiling or other fixed structures, saving space and facilitating installation and disassembly. The magnet connecting part provides a quick fixing method without drilling holes or installation tools, which is especially suitable for scenarios that require frequent movement or temporary fixing. The hanging hole allows the user to firmly install the support base 3 at the desired position through fasteners such as screws and nails, ensuring the stability for long-term use. In actual application, a suitable connecting part can be selected and set according to the usage scenario and requirements, including but not limited to the specific solutions listed above.

[0088] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
