Description

Technical Field

[0001] This application relates to projection devices, and more specifically to a new projector structure. Background Art

[0002] A projector is a device that can project images or videos onto a white wall or a screen. When a home projector is in use, it is sometimes necessary to adjust the projection height so that the projected image appears at a suitable horizontal height. Common methods for adjusting the height of a projector include a manual height adjustment mechanism and an automatic height adjustment mechanism. The manual height adjustment mechanism of some projectors uses a telescopic rod to support the projector body. The length of the telescopic rod is variable and can be directly fixed at any length position. Therefore, when the height needs to be adjusted, the projector body can be directly lifted or lowered. The telescopic rod of the projector is usually completely exposed in the retracted state. During transportation or storage, the telescopic rod is not protected, which may cause the surface of the telescopic rod to be pressed and dented, ultimately affecting the normal telescoping of the telescopic rod, and there is room for improvement. Summary of the Utility Model

[0003] The purpose of this application is to overcome the above deficiencies of the prior art and provide a new projector structure to improve the protection of the telescopic rod.

The fixed end of the telescopic rod penetrates into the vertical guard plate and is fixedly connected to the base; when the telescopic rod is in a fully retracted state, the telescopic rod is inside the vertical guard plate.

[0005] In an optional solution, when the telescopic rod is in a fully retracted state, the vertical guard plate covers the side surface of the projector body.

[0006] In an optional solution, there are two vertical guard plates symmetrically arranged on both sides of the base. The telescopic rods correspond to the vertical guard plates one by one. When the telescopic rods are in a fully retracted state, the projector body is placed between the two vertical guard plates.

[0007] In an optional solution, a vertical hole is provided inside the vertical guard plate, and the telescopic rod in the fully retracted state is placed in the vertical hole.

[0009] In an alternative solution, when the telescopic rod is in a fully retracted state, the top surface of the rotating shaft member is flush with the top surface of the vertical guard plate, and the top surface of the projector body is flush with the top surface of the vertical guard plate.

[0010] In an alternative solution, a screw rod penetrating through the side wall of the projector body penetrates into the rotating shaft member. A nut is also provided inside the rotating shaft member. The nut is screwed into the screw rod, and the screw rod serves as the central axis for the rotation of the rotating shaft member relative to the side wall of the projector body.

[0011] In an alternative solution, the projector body is provided with two lenses, a display screen, and a centrifugal fan. The display screen is located between the two lenses, and the air inlet of the centrifugal fan faces directly the air inlet passage between the display screen and the lenses.

[0027] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0029] Referring to "embodiments" herein means that the specific features, structures or characteristics described in conjunction with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0030] An embodiment of the present application is a novel projector structure, and its specific structure is as Figures 1 to 10 shown.

[0031] Combined with Figure 1 and Figure 2As shown in the figure, the projector structure includes a projector main body 10, a base 20, and at least one telescopic rod 40. A vertical guard plate 30 is provided on the base 20. The movable end of the telescopic rod 40 is rotatably connected to the side surface of the projector main body 10, and the fixed end of the telescopic rod 40 passes through the vertical guard plate 30 and is fixedly connected to the base 20. When the telescopic rod 40 is in a fully retracted state, the telescopic rod 40 is located in the vertical guard plate 30. When the projector main body 10 descends to the lowest height, the telescopic rod 40 is fully retracted, and the entire telescopic rod 40 is located in the vertical guard plate 30. Therefore, the protection of the telescopic rod 40 is improved, and it is not easy to damage the telescopic rod 40 during transportation or storage. At the same time, the telescopic rod 40 being hidden inside can enhance the integrity of the product and improve the appearance effect of the product.

[0032] In some embodiments, as Figure 1 shown, when the telescopic rod 40 is in a fully retracted state, the vertical guard plate 30 covers the side surface 101 of the projector main body 10. At this time, the vertical guard plate 30 and the projector main body 10 form an integral body, improving the overall appearance effect of the entire product. The cross-sectional shape of the vertical guard plate 30 is not limited to Figure 1 the shape shown. In other embodiments, the cross-sectional shape of the vertical guard plate 30 can also be other shapes, such as a rectangle.

[0033] In some embodiments, as Figure 1 and Figure 2 shown, there are two vertical guard plates 30 and they are symmetrically arranged on both sides of the base 20. The telescopic rods 40 correspond to the vertical guard plates 30 one by one. When the telescopic rods 40 are in a fully retracted state, the projector main body 10 is placed between the two vertical guard plates 30, that is, the vertical guard plates 30 are respectively arranged on the left and right sides of the projector main body 10, and the side surface 101 of the projector main body 10 is respectively covered by the vertical guard plates 30, enhancing the integrity of the entire projector and also enhancing the protection of the side surface 101 of the projector main body 10.

[0034] In other embodiments, there can also be only one vertical guard plate. The vertical guard plate can be arranged on the left side, right side, or rear side of the projector main body, that is, the telescopic rod is correspondingly rotatably connected to the left side, right side, or rear side of the projector main body. For example Figure 7 shown, the projector is in a folded state. At this time, the lens of the projector main body 10 faces upward, the bottom of the projector main body 10 is attached to the base 20, and there is only one vertical guard plate 30 and the vertical guard plate 30 is in a relatively narrow column shape. The vertical guard plate 30 is arranged on one side of the projector main body; as Figure 8 shown for the usage state of the projector, the projector main body 10 rises, and the telescopic rod 40 inside the vertical guard plate 30 is pulled out synchronously. The projector main body 10 rotates around the connection with the telescopic rod 40 to a suitable projection angle. For example Figure 9As shown, the projector is in the retracted state. At this time, the lens of the projector body 10 faces forward. There is only one vertical guard plate 30, and the vertical guard plate 30 is in a narrow column shape. The vertical guard plate 30 is provided at the rear side of the projector body 10; as Figure 10 shown is the usage state of the projector. The projector body 10 rises, and the telescopic rod 40 inside the vertical guard plate 30 is pulled out synchronously. The projector body 10 rotates around the connection with the telescopic rod 40 to a suitable projection angle.

[0035] In some embodiments, in combination with Figure 3 and Figure 4 shown, a vertical hole 31 is provided inside the vertical guard plate 30. The telescopic rod 40 in the fully retracted state is placed in the vertical hole 31. In other embodiments, the vertical hole can also be replaced by a vertical groove opened on the side wall of the vertical guard plate, and the telescopic rod in the fully retracted state is placed in the vertical groove.

[0036] In some embodiments, in combination with Figure 3 and Figure 4 shown, at the upper end of the vertical hole 31 is a receiving groove 32, and the receiving groove 32 communicates with the vertical hole 31. A rotating shaft member 50 is fixed to the movable end of the telescopic rod 40, and the rotating shaft member 50 forms a rotational connection with the side wall of the projector body 10. The rotational connection structure between the rotating shaft member 50 and the side wall of the projector body 10 can adopt a screw-nut structure, a silicone rotating shaft structure, or a damping bearing structure. As Figure 6 shown is one of the usage states of the projector. Among them, both telescopic rods 40 extend a certain length, the projector body 10 is lifted to a suitable height, and the projector body 10 rotates a certain angle relative to the telescopic rod 40.

[0037] When the telescopic rod 40 is in the fully retracted state, as Figure 1 shown, the entire rotating shaft member 50 is in the receiving groove 32. In addition, as Figure 1 shown, when the telescopic rod 40 is in the fully retracted state, the top surface of the rotating shaft member 50 is flush with the top surface of the vertical guard plate 30, and the top surface of the projector body 10 is flush with the top surface of the vertical guard plate 30, making the entire top surface of the projector flatter.

[0038] In some embodiments, as Figure 3 shown, a screw 51 penetrating through the side wall of the projector body 10 penetrates into the rotating shaft member 50. A nut 52 is also provided inside the rotating shaft member 50, and the nut 52 is screwed into the screw 51 to fixedly connect the rotating shaft member 50 to the side wall of the projector body 10. The screw 51 is the axis for the rotating shaft member 50 to rotate relative to the side wall of the projector body 10, that is, the screw 51 serves as the axis for the projector body 10 to rotate relative to the telescopic rod 40. If the tightening force of the nut 52 on the screw 51 is large, the rotation resistance of the projector body 10 becomes larger, and vice versa, the rotation resistance of the projector body 10 becomes smaller.

[0039] In some embodiments, as Figure 5 shown, the projector main body 10 is provided with two lenses 61, a display screen 62 and a centrifugal fan 64. The display screen 62 is located between the two lenses 61. The air inlet 641 of the centrifugal fan 64 is directly opposite to the air inlet passage 63 between the display screen 62 and the lens 61. The projector main body 10 is also provided with a light-emitting plate 67. A heat dissipation fin 68 is fixedly connected to the back of the light-emitting plate 67. The air outlet 642 of the centrifugal fan 64 is connected to the air outlet passage 65. The heat dissipation fin 68 is located in the air outlet passage 65. External air first enters the centrifugal fan 64 through the air inlet passage 63. The centrifugal fan 64 then blows the air towards the air outlet passage 65. After passing through the heat dissipation fin 68, the air is then discharged to the outside. Therefore, the air can take away the heat of the display screen 62 and the lens 61 in the air inlet passage 63, and then take away the heat of the heat dissipation fin 68 in the air outlet passage 65.

[0040] In some embodiments, as Figure 1 shown, a handle 100 is provided on the top surface of the projector main body 10, which is convenient for directly lifting the projector main body 10 to adjust its height, or the handle 100 can be used to directly lift the entire projector, improving the portability of the projector.
