[0044] With the development of electronic technology and the application of multimedia technology, projectors are becoming more and more popular because of their ultra-large-screen visual experience and their wide range of application scenarios. As a product that meets scenario-based needs, smart projection products need to cover more functional scenarios. Projection products are different from laser TVs, LCD TVs and other products. They are basically fixed after being placed. Smart projectors usually follow the needs of users and can be picked up at any time and used immediately. In the related art, the smart projector has a power cord, which is connected to the power socket through the power cord to power the smart projector. However, in the related art, every time the smart projector is moved, it is necessary to plug and unplug the power cord, resulting in a poor user experience.

[0045] In order to solve the above problems, an embodiment of the present application provides a projection device, by setting a conductive component, the conductive component includes a first conductive terminal and a second conductive terminal; the first conductive terminal is set on the pan-tilt head and electrically connected to the power port; the second conductive terminal is set on the projector and electrically connected to the first circuit board; in this way, when the projector is set on the pan-tilt head, the first conductive terminal and the second conductive terminal are in contact and electrically conductive, and when the projector and the pan-tilt head are disassembled, the first conductive terminal and the second conductive terminal are separated and powered off, thereby realizing contact power supply and separation power off, and the user's operation is flexible. In this way, there is no need to repeatedly plug and unplug the power cord when moving the projector, which improves the user's usage experience; in addition, by making the projector and the pan-tilt head detachable, the projector can be adapted to different pan-tilt heads according to specific needs to meet different application scenarios.

[0046] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0047] Please refer to Figure 1 and Figure 2 As shown, an embodiment of the present application provides a projection device 100 , which includes a projector 120 , and the projector 120 includes but is not limited to a laser projector 120 .

[0048] The following will take the laser projector 120 as an example for introduction.

[0049] Please refer to Figures 1 to 8As shown, the projector 120 provided in the embodiment of the present application includes a housing, a projection host located in the housing, and a first circuit board, the first circuit board being, for example, a printed circuit board (PCB). When the first circuit board is powered on, the first circuit board supplies power to the projection host.

[0050] In some embodiments, please refer to Figure 1 and Figure 2 As shown, the projection device 100 further includes a pan-tilt platform 110, and a projector 120 is disposed on the pan-tilt platform 110 and is detachably connected to the pan-tilt platform 110. The pan-tilt platform 110 can provide a supporting foundation for the projector 120.

[0051] The projector 120 needs to be powered on, but in order to avoid always carrying a power cord on the projector 120, in some embodiments, the projection device 100 also includes a conductive component, which includes a first conductive terminal 131 and a second conductive terminal 132. It can be understood that the first conductive terminal 131 matches the second conductive terminal 132.

[0052] In some embodiments, the first conductive terminal 131 is disposed on the gimbal 110, and a power port 111 electrically connected to the first conductive terminal 131 is disposed on the gimbal 110, and the power port 111 is configured to be electrically connected to an external power source; the second conductive terminal 132 is disposed on the projector 120 and electrically connected to the first circuit board. When the projector 120 is disposed on the gimbal 110, and the power port 111 is electrically conductive to the power source, the first conductive terminal 131 and the second conductive terminal 132 are in contact and electrically conductive, so that the power source supplies power to the first circuit board through the power port 111, the first conductive terminal 131, and the second conductive terminal 132 in sequence.

[0053] Exemplarily, the first conductive terminal 131 is disposed on the side of the gimbal 110 facing the projector 120, and the second conductive terminal 132 is disposed on the side of the gimbal 110 facing the projector 120. The first conductive terminal 131 and the second conductive terminal 132 are disposed opposite to each other, so that when the projector 120 is disposed on the gimbal 110, the first conductive terminal 131 and the second conductive terminal 132 are in contact and electrically connected to achieve electrical conduction.

[0054] In addition, the first conductive terminal 131 and the power port 111 can be electrically connected via a first conductive wire, and the power port 111 can be connected between the power port 111 and a power source via an adapter, that is, one end of the adapter matches the power port 111, and the other end of the adapter matches the power source, so that the power source can be powered to the projection device 100 through the adapter.

[0055] In the embodiment of the present application, the projector 120 and the pan-tilt head 110 are independent structures. When the projector 120 is set on the pan-tilt head 110, the projector 120 and the pan-tilt head 110 are connected through the first conductive terminal 131 and the second conductive terminal 132 to achieve contact power supply; when the projector 120 is removed from the pan-tilt head 110, the first conductive terminal 131 and the second conductive terminal 132 are separated from each other and the power is cut off; that is, the first conductive terminal 131 and the second conductive terminal 132 are contacted for power supply and separated for power off. When moving the projector 120, there is no need to constantly plug and unplug the power cord, and the user's operation is more flexible, thereby improving the user's experience; in addition, there is no need to drag a power cord on the projector 120, thereby improving the overall aesthetics of the projector 120.

[0056] In some embodiments, the first conductive terminal 131 includes a first conductive contact portion, and the second conductive terminal 132 includes a second conductive contact portion. When the projector 120 is disposed on the pan / tilt platform 110 , the first conductive contact portion contacts and is electrically connected to the second conductive contact portion.

[0057] The first conductive contact portion matches the second conductive contact portion, so that when the first conductive contact portion contacts the second conductive contact portion, the conductive reliability of the first conductive contact portion and the second conductive contact portion can be improved.

[0058] Exemplarily, the first conductive contact portion and the second conductive contact portion may be columnar structures, as long as they are easy to contact and conduct, and no specific limitation is made herein.

[0059] In some embodiments, please refer to Figures 3 to 5 As shown, the gimbal 110 has a first cavity, and the top of the gimbal 110 has a first through hole connected to the first cavity, the first conductive terminal 131 is arranged in the first cavity and the first conductive contact portion extends out of the gimbal 110 through the first through hole, so that the first conductive contact portion faces the projector 120, that is, the first conductive terminal 131 is partially embedded in the gimbal 110, so that the structural compactness of the gimbal 110 can be improved; in addition, it can also avoid the risk of the first conductive terminal 131 being completely exposed to the outside of the gimbal 110 and being easily damaged, thereby extending the life of the first conductive terminal 131.

[0060] Exemplarily, the pan / tilt head 110 includes an upper shell 112 and a lower shell 113, the upper shell 112 and the lower shell 113 are together arranged to form a first cavity, and the first through hole is arranged on the upper shell 112.

[0061] In some embodiments, the projector 120 has a second cavity, and the side of the projector 120 facing the pan-tilt head 110 has a second through hole connected to the second cavity, the second conductive terminal 132 is disposed in the second cavity, and the second conductive contact portion extends out of the projector 120 along the second through hole so that the second conductive contact portion faces the first conductive contact portion, so that when the projector 120 is disposed on the pan-tilt head 110, the second conductive contact portion contacts and is electrically connected to the corresponding first conductive contact portion on the pan-tilt head 110.

[0062] It is understandable that part of the second conductive terminal 132 is embedded in the projector 120 . This can improve the compactness of the structure of the projector 120 while avoiding the risk of the second conductive terminal 132 being completely exposed to the outside of the projector 120 and being easily damaged, thereby extending the service life of the second conductive terminal 132 .

[0063] In some embodiments, the first conductive contact portion can float in the first through hole along the axial direction of the first through hole. The second conductive contact portion can float in the second through hole along the axial direction of the second through hole, so that when the projector 120 and the pan / tilt head 110 are in a disassembled state, part of the first conductive contact portion extends out of the surface of the pan / tilt head 110, and part of the second conductive contact portion extends out of the surface of the projector 120, so that the first conductive contact portion and the second conductive contact portion can contact and be electrically connected when the projector 120 is subsequently installed on the pan / tilt head 110.

[0064] When the projector 120 is installed on the pan-tilt head 110, the first conductive contact portion and the second conductive contact portion are in contact with each other and are electrically connected; in addition, under the action of mutual resistance, the first conductive contact portion moves along the first through hole toward the side away from the projector 120, and the second conductive contact portion moves toward the side away from the pan-tilt head 110. The first conductive contact portion and the second conductive contact portion can be hidden in the corresponding first through hole and the second through hole respectively while ensuring that the two are in contact with each other, so as to improve the overall aesthetics and safety and reliability of the projection device 100.

[0065] In some embodiments, the first conductive terminal 131 further includes a first elastic portion, which is disposed between the bottom wall of the first cavity and the first conductive contact portion, so that the first conductive contact portion can float along the axial direction of the first through hole. In addition, when the first conductive contact portion is not subjected to external force, the first elastic portion drives the first conductive contact portion to protrude from the surface of the pan / tilt platform 110 through its own elastic force. When the first conductive contact portion is subjected to external thrust force, the first conductive contact portion overcomes the elastic force of the first elastic portion and moves toward the first through hole, so that the first conductive contact portion can be hidden in the first through hole.

[0066] In some embodiments, the second conductive terminal 132 also includes a second elastic portion, which is disposed between the bottom wall of the second cavity and the second conductive contact portion, so that the second conductive contact portion can float along the axial direction of the second through hole. In addition, when the second conductive contact portion is not subjected to external force, the second elastic portion drives the second conductive contact portion to protrude from the surface of the projector 120 through its own elastic force; and when the second conductive contact portion is subjected to external resistance force, the second conductive contact portion overcomes the elastic force of the second elastic portion and moves toward the second through hole, so that the second conductive contact portion can be hidden in the second through hole.

[0067] Exemplarily, the first elastic part and the second elastic part may be structures such as springs, elastic pads, and elastic columns, respectively. The specific structure may be adaptively selected according to actual needs and is not limited here.

[0068] Exemplarily, the first conductive terminal 131 may be a Pogo pin terminal, and the second conductive terminal 132 may also be a Pogo pin terminal matching the first conductive terminal 131 .

[0069] Thus, in the embodiment of the present application, by setting the first conductive terminal 131 and the second conductive terminal 132 as, for example, Pogo pin terminals respectively, since the Pogo pin terminals can float along the axial direction, they can withstand vibration and impact, or when the projector 120 or the pan / tilt head 110 is subjected to severe tension, the first conductive terminal 131 and the second conductive terminal 132 are more easily disconnected, thereby avoiding the risk of injuring the user or damaging the projection device 100; in addition, the pan / tilt head 110 and the projector 120 are in contact and electrically connected through the first conductive terminal 131 and the second conductive terminal 132, which can save space on the first circuit board, thereby miniaturizing the projector 120; secondly, the contact point of the Pogo pin terminal is more stable, and when the adapter connecting the power port 111 and the power source is compressed, the contact point between the first conductive terminal 131 and the second conductive terminal 132 is not easy to move, thereby improving the reliability of the power supply to the projector 120 through the pan / tilt head 110.

[0070] In some embodiments, the conductive component includes at least two first conductive terminals 131 and at least two second conductive terminals 132 , wherein one first conductive terminal 131 is disposed opposite to one second conductive terminal 132 .

[0071] In the present application, high-power current can be supported by providing at least two first conductive terminals 131 and at least two second conductive terminals 132. Exemplarily, the conductive component includes four first conductive terminals 131 and four second conductive terminals 132, so that a high-power current of, for example, 6A can be supported, thereby realizing a long-term reliable power supply to the projector 120.

[0072] In some embodiments, please refer to Figures 1 to 6 As shown, the projection device 100 also includes a first bracket 140, which is arranged on the pan-tilt head 110 and is detachably connected to the pan-tilt head 110. The projector 120 is arranged on the first bracket 140, and the projector 120 and the first bracket 140 are pivotally connected, that is, the projector 120 can rotate relative to the first bracket 140. For example, the projector 120 and the first bracket 140 are rotatably connected via a rotating shaft, and the rotating shaft is arranged in a horizontal direction, so that the projector 120 can rotate around the rotating shaft relative to the first bracket 140 to adjust the pitch angle of the projector 120 to meet the user's requirements for different projection angles.

[0073] The second conductive terminal 132 is disposed at one end of the first bracket 140 facing the pan / tilt head 110, wherein the second conductive terminal 132 and the first circuit board can be electrically connected via a conductive line, so that the first bracket 140 and the projector 120 form a whole, and the first bracket 140 and the pan / tilt head 110 are detachably connected. When the first bracket 140 and the pan / tilt head 110 are installed, the first conductive terminal 131 and the second conductive terminal 132 are in contact and electrically connected; when the first bracket 140 and the pan / tilt head 110 are disassembled, the first conductive terminal 131 and the second conductive terminal 132 are separated and powered off, thereby improving the user's operational flexibility.

[0074] It can be understood that in the embodiment of the present application, by setting the first bracket 140 between the projector 120 and the pan-tilt head 110, it can be adapted to occasions where there is no structure for placing the projection device 100, so as to meet more application scenarios of users and enhance the competitiveness of the product.

[0075] In some embodiments, the first bracket 140 includes a first connecting portion 141 and first supporting portions 142 located at both ends of the first connecting portion 141, the first supporting portion 142 is bent toward an end away from the gimbal 110, and illustratively, the first bracket 140 is formed as, for example, a U-shaped bracket structure, the projector 120 is located between the two first supporting portions 142 and is pivotally connected to the two first supporting portions 142, that is, the two first supporting portions 142 are respectively rotatably connected to the housing of the projector 120 via a rotating shaft, so that the projector 120 can rotate around the rotating shaft relative to the first supporting portion 142 to adjust the pitch angle of the projector 120.

[0076] The second conductive terminal 132 may be disposed on the first connection portion 141. Exemplarily, the first connection portion 141 is a connection plate parallel to the upper surface of the pan-tilt head 110, so that when the first bracket 140 is detachably connected to the pan-tilt head 110 through the first connection portion 141, the stability between the first bracket 140 and the pan-tilt head 110 is improved, thereby improving the support stability of the projector 120.

[0077] In addition, the first support portion 142 is, for example, a support column, a support plate or other structure, and any structure that can support the projector 120 is not limited herein.

[0078] In some embodiments, the conductive wire connecting the second conductive terminal 132 and the first circuit board can be embedded in the first support portion 142, that is, the first support portion 142 has a receiving cavity, and the conductive wire is embedded in the receiving cavity to avoid the conductive wire being exposed to the outside and affecting the overall aesthetics of the projection device 100.

[0079] In order to improve the convenience of disassembly and assembly between the first bracket 140 and the gimbal 110, in some embodiments, the side of the gimbal 110 facing the first connecting portion 141 has one of the first card slot 143 and the first card protrusion 115, and the side of the first connecting portion 141 facing the gimbal 110 has the other of the first card slot 143 and the first card protrusion 115. Exemplarily, the side of the gimbal 110 facing the first connecting portion 141 is provided with the first card protrusion 115, and the side of the first connecting portion 141 facing the gimbal 110 is provided with the first card slot 143, and the first connecting portion 141 is connected to the gimbal 110 through the first card protrusion 115 and the first card slot 143.

[0080] Alternatively, a first magnetic part is provided at one end of the first connecting portion 141 facing the gimbal 110, and a second magnetic part is provided on the side of the gimbal 110 facing the first connecting portion 141. The first magnetic part and the second magnetic part are magnetically adsorbed to each other. In this way, when the first connecting portion 141 is connected to the gimbal 110, the connection can be achieved through the magnetic adsorption between the first magnetic part and the second magnetic part. The disassembly and assembly method is simple, easy to implement, and low in cost.

[0081] The first magnetic member and the second magnetic member may both be magnets; or, one of the first magnetic member and the second magnetic member is a magnet, and the other is made of a magnetic material that can be magnetically attracted by a magnet.
