Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0055] The purpose of this invention is to provide a projector support device that can not only charge the user's mobile device, but also improve the linkage between the user's mobile phone and the projector, while reducing heat loss during charging and reducing interference between NFC and wireless charging.

[0056] To achieve the above objectives, the present invention provides the following technical solution:

[0057] Please see Figures 1 to 8 This embodiment provides a projector support device, including: a multi-functional base 100 and a support rod 200; the multi-functional base 100 includes an upper shell assembly 110, a lower shell assembly 120, and an integrated electrical module 130 installed between the two; the upper shell assembly 110 has a receiving cavity inside; the integrated electrical module 130 is fixedly connected to the upper shell assembly 110 and located inside the receiving cavity; the lower shell assembly 120 is detachably connected to the upper shell assembly 110 to seal the receiving cavity; the integrated electrical module 130 includes a wireless charging transmitter coil 131 for wirelessly charging a device placed on the multi-functional base 100 and an NFC board 132 for near-field communication pairing with a mobile device; the support rod 200 is used to support a cannon projector 300; the support rod 200 includes a first end and a second end; the first end is connected to the multi-functional base 100, and the second end is connected to the cannon projector 300; a wire for connecting the cannon projector 300 and the NFC board 132 passes through the support rod 200.

[0058] In this embodiment, the multi-functional base 100 is a circular base with a first end of a support rod 200 connected to its side. The second end of the support rod 200 is connected to the projector 300. The support rod 200 is a structure that can be bent and deformed at will to facilitate the adjustment of the angle of the projector 300. The support rod 200 is a hollow structure with wires running through it. These wires connect the NFC board 132 and the projector 300 to achieve the purpose of pairing the mobile phone and the projector 300.

[0059] In this example, the multi-functional base 100 has an internal cavity, and the integrated electrical module 130 is located inside the cavity. It is suspended from the lower side of the upper shell assembly 110, and the bottom of the upper shell assembly 110 is connected to the lower shell assembly 120 by screws. That is to say, the wireless charging transmitting coil 131 is placed at the top of the module, close to the upper shell assembly 110, which reduces the transmission distance and improves the transmission power.

[0060] It should be noted that the wireless charging transmitter coil 131 is installed in the middle of the receiving cavity, while the NFC board 132 is installed near the edge of the receiving cavity.

[0061] In other words, the multi-functional base 100 provided in this application firstly has the function of supporting the projector 300 via the support rod 200; in addition, the multi-functional base 100 has an integrated electrical module 130 installed inside its cavity, which includes a wireless charging transmitter coil 131 and an NFC board 132. The wireless charging transmitter coil 131 can wirelessly charge mobile devices, eliminating the need for users to carry additional charging equipment and reducing the complexity of on-site wiring; in addition, the NFC board 132 can pair with mobile phones via Near Field Communication (NFC) to establish a connection between the mobile phone and the projection device, thereby improving the linkage between the mobile phone and the projection device, increasing the pairing speed, eliminating the need for searching or entering passwords in traditional methods, reducing the user's learning cost, saving time, and making data transmission easier.

[0062] Preferably, the upper shell assembly 110 includes: a plastic upper shell 111, a thermally conductive glass 112, and an anti-slip silicone ring 113; the plastic upper shell 111 includes a circular base plate 1111 and a side wall 1112 disposed around the circumference of the base plate 1111, the base plate 1111 and the side wall 1112 are fixedly connected to form a receiving cavity, and a recessed first groove 1113 is provided on the side of the base plate 1111 away from the receiving cavity; the thermally conductive glass 112 is installed in the first groove 1113; the anti-slip silicone ring 113 is laid on the side of the base plate 1111 away from the receiving cavity, and the anti-slip silicone ring 113 is located on the outer periphery of the thermally conductive glass 112.

[0063] Specifically, such as Figure 2 and Figure 3 As shown, the plastic upper shell 111 is a cylindrical structure that is generally circular and has an opening on one side. It includes a circular base plate 1111 and a side wall 1112 connected to the circumference of the base plate 1111. During use, it is in an inverted state. The outer side of the base plate 1111, that is... Figure 2 The topmost outer side of the plastic upper shell 111 is the charging area for placing mobile devices (such as mobile phones), which corresponds to the wireless charging transmitter coil 131 located inside the receiving cavity. Therefore, in this embodiment, a circular first groove 1113 is provided at this location, and an insulating thermally conductive glass 112 is laid inside the first groove 1113 to improve the thermal conductivity of the plastic upper shell 111. Furthermore, to prevent the device from slipping, concentric anti-slip silicone rings 113 are provided on the circumferential edge of the first groove 1113.

[0064] Preferably, the lower shell assembly 120 includes: a plastic lower shell 121 and silicone feet 122; the plastic lower shell 121 is connected to the side wall 1112 to close the receiving cavity, and a connecting nut 1211 is provided in the middle of the plastic lower shell 121 for hoisting the plastic lower shell 121; the silicone feet 122 are laid on the lower side of the plastic lower shell 121 to prevent the multi-functional base 100 from sliding.

[0065] Specifically, such as Figure 5 As shown, the shape and size of the lower plastic shell 121 are the same as the opening of the upper plastic shell 111. That is to say, the lower plastic shell 121 can be fitted into the opening at the bottom of the upper plastic shell 111, thus forming a closed cavity to support other components. A connecting nut 1211 is provided in the middle of the lower plastic shell 121, which can be used to suspend the lower plastic shell 121 by installing screws. In addition, to prevent the multi-functional base 100 from sliding, silicone pads 122 are laid on the bottom of the lower plastic shell 121.

[0066] In this embodiment, both the upper plastic shell 111 and the lower plastic shell 121 are made of insulating plastic, and both are integrally formed by injection molding; this arrangement can reduce manufacturing costs.

[0067] Preferably, the integrated electrical module 130 further includes: a thermally conductive aluminum plate 133, heat dissipation fins 134, a plastic bracket 135, and a wireless charging mainboard 136; the thermally conductive aluminum plate 133 is used to support the wireless charging transmitting coil 131 and conduct the heat generated by the wireless charging transmitting coil 131 during operation; the heat dissipation fins 134 are installed on the underside of the thermally conductive aluminum plate 133 for dissipating heat from the thermally conductive aluminum plate 133; the plastic bracket 135 includes a support plate 1351 and connecting ears 1352 disposed on both sides of the support plate 1351, the support plate 1351 is used to accommodate the thermally conductive aluminum plate 133, and the support plate 1351 is provided with a first through hole 1353 for the heat dissipation fins 134 to pass through, and the connecting ears 1352 are used to connect to the inner wall of the plastic upper shell 111; the wireless charging mainboard 136 is detachably connected to the underside of the plastic bracket 135, and the wireless charging mainboard 136 is electrically connected to the wireless charging transmitting coil 131.

[0068] Specifically, such as Figures 6 to 8As shown, the integrated electrical module 130, from top to bottom, consists of a wireless charging transmitting coil 131, a heat-conducting aluminum plate 133, a plastic bracket 135, and a wireless charging mainboard 136. Two heat dissipation fins 134 are symmetrically arranged on the lower side of the heat-conducting aluminum plate 133, and the plastic bracket 135 has a first through hole 1353 to avoid the heat dissipation fins 134. The heat-conducting aluminum plate 133 is designed to transfer the heat generated by the wireless charging transmitting coil 131 to the heat dissipation fins 134. The plastic bracket 135 secures the heat-conducting aluminum plate 133 and the wireless charging transmitting coil 131 it supports to the plastic upper shell 111. Specifically, the connecting ears 1352 of the plastic bracket 135 can be connected to the base plate 1111 of the plastic upper shell 111 by screws. The plastic bracket 135 is also made by injection molding and its material is plastic. That is to say, the plastic bracket 135 also has the function of preventing heat from being transferred to the wireless charging motherboard 136 and causing it to be damaged. In this embodiment, two heat dissipation fins 134 are provided on the lower side of the heat-conducting aluminum plate 133. Of course, the number of them can be adjusted according to the actual situation. The setting of heat dissipation fins 134 can control the temperature of the charging module below 60°C, reduce the temperature, and improve the charging rate.

[0069] Preferably, the plastic lower shell 121 has a second through hole at the position corresponding to the heat dissipation fin 134, and a metal aluminum plate 1212 is embedded in the second through hole. The metal aluminum plate 1212 is connected to the heat dissipation fin 134 through a thermally conductive silicone pad 123. The metal aluminum plate 1212 is used to conduct heat from the heat dissipation fin 134. The upper side of the plastic lower shell 121 is provided with a mounting groove 1213 for installing the thermally conductive silicone pad 123 at the position corresponding to the heat dissipation fin 134.

[0070] Understandably, in order to conduct the heat from the heat dissipation fins 134 to the outside of the multi-functional base 100, in this embodiment, a second through hole is provided in the plastic lower shell 121 at the position corresponding to the heat dissipation fins 134, and a metal aluminum plate 1212 is provided in the second through hole; it should be noted that the metal aluminum plate 1212 is pre-embedded in the plastic lower shell 121 during the injection molding process, so as to reduce the processing and manufacturing difficulty.

[0071] Another important point is that, in this embodiment, a thermally conductive silicone pad 123 is also laid between the aluminum plate 1212 and the heat dissipation fins 134. In the installed state, the heat dissipation fins 134, the thermally conductive silicone pad 123 and the aluminum plate 1212 are pressed together, that is, there is no gap between the three. This arrangement is to eliminate the gap between the heat dissipation components, so that the heat dissipation method is heat conduction rather than heat dissipation through convection, which can improve the heat dissipation performance. At the same time, in order to prevent the thermally conductive silicone pad 123 from falling out of its functional position, a mounting groove 1213 is also provided on the outer periphery of the second through hole for placing and restricting the thermally conductive silicone pad 123.

[0072] Preferably, the thermally conductive aluminum plate 133 has a circular structure, and its edge is vertically provided with a lip to isolate the electromagnetic field of the wireless charging transmitting coil 131; the inner side of the bottom plate 1111 of the plastic upper shell 111 is attached with a metal aluminum foil 114 to shield the interference signal of wireless charging.

[0073] Understandably, to prevent interference between NFC and wireless charging, which could lead to NFC failure or reduced wireless charging speed, in this embodiment, the thermally conductive aluminum plate 133 on the underside of the wireless charging transmitter coil 131 is designed with lip edges around its perimeter as a metal shielding layer to isolate the electromagnetic field of the wireless charging transmitter coil 131. Metal aluminum foil 114 is attached to the ribs on the underside of the plastic upper shell 111 to further shield interference signals from wireless charging. These two elements isolate the wireless charging transmitter coil 131 and the NFC board 132 antenna into two relatively independent compartments, reducing electromagnetic interference and improving their efficiency and stability during use. For details, please refer to [link / reference needed]. Figure 4 , Figure 7 and Figure 8 .

[0074] Preferably, the wireless charging motherboard 136 is equipped with an indicator light, and the plastic upper shell 111 has a third through hole 1114 at the position of the indicator light. A hot-melt light guide column 115 is provided between the indicator light and the third through hole 1114. The hot-melt light guide column 115 is fixedly connected to the plastic upper shell 111 and is used to make the light of the indicator light more uniform.

[0075] In this embodiment, the wireless charging motherboard 136 has an indicator light, and a third through hole 1114 is also provided at the corresponding position on the plastic upper shell 111. The indicator light can display the charging status. When a mobile device is placed on the top surface of the multi-functional base 100, the LED indicator light will automatically light up and will turn off after a 5-minute delay after charging is completed. Furthermore, in order to make the light emitted by the indicator light more uniform, a hot-melt light guide post 115 is also provided on the lower side of the plastic upper shell 111 corresponding to the position of the third through hole 1114.

[0076] Preferably, thermal grease is filled between the wireless charging transmitting coil 131 and the thermally conductive aluminum plate 133, between the thermally conductive aluminum plate 133 and the plastic bracket 135, and between the metal aluminum plate 1212 and the heat dissipation fins 134.

[0077] In this embodiment, in order to improve heat transfer efficiency, thermally conductive silicone grease is filled between the various components in the heat transfer process to seal the air gaps, so that the heat transfer method is heat conduction rather than heat convection.

[0078] Preferably, the side wall 1112 of the multifunctional base 100 is provided with a mounting portion 140 for mounting the support rod 200.

[0079] Specifically, such as Figure 2 As shown, in order to facilitate the installation of the support rod 200, a boss is provided at the edge of the multi-functional base 100 as the mounting part 140 of the support rod 200, and the mounting part 140 is connected to the receiving cavity to allow the wires to be threaded through.

[0080] This application also provides a multi-functional cannon-type projector device, including the projector support device as described above. Therefore, the multi-functional cannon-type projector device also has the beneficial effects of the projector support device described above.
