[0034] The core of this utility model is to disclose a projector to meet the outdoor use needs of projectors and broaden the application scenarios of projectors.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0036] like Figures 1-2 As shown in the figure, this utility model embodiment discloses a projector, including a gimbal 100, a battery pack 200 and a projector body 300.

[0037] The battery pack 200 is detachably connected to the pan-tilt unit 100, and the projector body 300 is detachably connected to the battery pack 200, which powers the projector body 300. The projector body 300 can be detachably connected to the pan-tilt unit 100 and can be connected to an AC power source.

[0038] When outdoor power supply from the mains (220 volts) is unavailable, battery pack 200 is used. Battery pack 200 preferably has a capacity of 600Wh and can output DC current suitable for the projector body 300, preferably 19 volts, ensuring the projector can support 3-5 hours of full-power projection. When indoor or outdoor power supply from the mains (220 volts) is available, battery pack 200 is not needed. It can be removed, and the projector body 300 can be connected to the pan / tilt unit 100 via a power adapter. The power adapter converts the mains AC power (220 volts) to 19 volts DC power. The specific structural diagram of the projector in this case is shown below. Figures 3-4 As shown.

[0039] The projector disclosed in this embodiment can use a battery pack 200 to power the projector body 300 when it is not possible to use AC power from the power grid outdoors. When it is possible to use AC power from the power grid indoors or outdoors, the battery pack 200 can be removed and the projector body 300 can be directly installed on the pan-tilt unit 100. This can meet the needs of using the projector outdoors and indoors, further broaden the application scenarios of the projector, and meet the needs of different users.

[0040] The projector body 300 and the battery pack 200 can be detachably connected. Specifically, they can be connected by fasteners or by snap-fit ​​connection. The specific connection method is not limited.

[0041] Furthermore, such as Figure 5 and Figure 7As shown, in some specific embodiments, the projector body 300 and the battery pack 200 are snapped together. The projector body 300 is provided with a first elastic hook 310, and the battery pack 200 is provided with a second elastic hook 210 that cooperates with the first elastic hook 310. An elastic hook button 330 is provided on either the projector body 300 or the battery pack 200. By pressing the elastic hook button 330, the first elastic hook 310 and the second elastic hook 210 can disengage, thus separating the projector body 300 from the battery pack 200. When the battery pack is needed, the projector body 300 is installed on the battery pack 200, so that the first elastic hook 310 and the second elastic hook 210 are engaged. When the battery pack 200 needs to be removed, pressing the elastic hook button 330 disengages the first elastic hook 310 and the second elastic hook 210, thus separating the projector body 300 from the battery pack 200.

[0042] To ensure a secure connection between the projector body 300 and the battery pack 200, at least two first elastic hooks 310 are provided, and they are respectively located on opposite sides of the projector body 300. The second elastic hook 210 and the elastic hook button 330 correspond one-to-one with the first elastic hook 310.

[0043] like Figures 5-7 As shown in the figure, the first elastic hook 310 is located on the left and right sides of the bottom surface of the projector body 300, the second elastic hook 210 is located on the left and right sides of the top surface of the battery pack 200, and the elastic hook button 330 is located on the left and right sides of the bottom surface of the projector body 300 and connected to the first elastic hook 310. During installation, the projector body 300 is placed on top of the battery pack 200, and the first elastic hook 310 hooks onto the second elastic hook 210 on the battery pack 200, thereby locking the projector body 300 and the battery pack 200. When it is necessary to disassemble the projector body 300 and the battery pack 200, press the elastic hook button 330 on both sides, the first elastic hook 310 and the second elastic hook 210 disengage, and the projector body 300 and the battery pack 200 can be separated.

[0044] Furthermore, such as Figure 5 and Figure 7 As shown, to ensure quick positioning of the projector body 300 and battery pack 200 during installation, one of the projector body 300 and battery pack 200 is provided with a first positioning boss 320, and the other is provided with a first positioning hole 220 that mates with the first positioning boss 320. The number of first positioning bosses 320 is at least two. The figure shows four first positioning bosses 320, respectively located around the bottom of the projector body 300. The first positioning holes 220 are located on the top of the battery pack 200, corresponding one-to-one with the first positioning bosses 320.

[0045] Furthermore, the first positioning boss 320 is frustum-shaped, and the shape of the first positioning hole 220 matches the shape of the first positioning boss 320. The frustum shape provides a guiding function. Those skilled in the art will understand that the first positioning boss 320 can also be other shapes.

[0046] Furthermore, such as Figures 8-9 As shown, the gimbal 100 includes a gimbal bracket 120 and a mounting plate 110. The mounting plate 110 is connected to the gimbal bracket 120, and both the projector body 300 and the battery pack 200 can be connected to the mounting plate 110. In order to adjust the pitch angle of the projector body 300, the mounting plate 110 is preferably hinged to the gimbal bracket 120, and the gimbal 100 is used to realize the 360-degree rotation and pitch angle adjustment of the projector body 300.

[0047] Furthermore, both the battery pack 200 and the projector body 300 can be connected to the mounting plate 110 via the connector 400. The connector 400 can be a bolt, the mounting plate 110 has through holes, and both the battery pack 200 and the projector body 300 have threaded holes that mate with the bolts.

[0048] Furthermore, such as Figures 8-9 As shown, in some specific embodiments, the connector 400 is a captive screw. The connector 400 is mounted on the mounting plate 110. Both the battery pack 200 and the projector body 300 are provided with threaded holes 240 that mate with the connector 400. Specifically, as shown... Figure 6 and Figure 7 As shown. Installation using captive screws is simple, convenient, and quick, and the connector 400 will not detach from the mounting plate 110 when the battery pack 200 or the projector body 300 is removed from the mounting plate 110, thus preventing loss.

[0049] Furthermore, to ensure the strength of the connection, the connector 400 includes at least two connectors arranged diagonally. Figures 8-9 The connectors 400 shown include four pieces, each disposed around the perimeter of the mounting plate 110. When the battery pack 200 is needed, it is mounted onto the mounting plate 110 via the connectors 400, and then the projector body 300 is mounted onto the battery pack 200. The connection is achieved by the first elastic hook 310 and the second elastic hook 210 engaging with each other. When the battery pack 200 is not needed, the projector body 300 can be directly mounted onto the mounting plate 110 of the pan-tilt unit 100 via the connectors 400.

[0050] Furthermore, such as Figures 6-8As shown, in order to position the battery pack 200 and the projector body 300 when they are respectively installed on the gimbal 100, the mounting plate 110 is provided with a second positioning boss 111, and the battery pack 200 and the projector body 300 are both provided with a second positioning hole 230 that cooperates with the second positioning boss 111. Figure 8 The second positioning protrusion 111 shown includes three protrusions arranged in a triangle. The second positioning holes 230 correspond one-to-one with the second positioning protrusions 111 and are respectively located on the bottom surfaces of the battery pack 200 and the projector body 300, as detailed below. Figures 6-7 As shown. Preferably, the second positioning boss 111 is shaped like a frustum.
