Description

Technical Field

[0001] The present application relates to the field of projection technology, and in particular to a projector heat flow duct conversion structure and a projector. Background Art

[0002] Projectors are highly streamlined optomechanical and electrical products, and their internal components are very sensitive to temperature. In addition to the complexity of the internal structure and the relatively stringent temperature requirements, projectors have higher heat dissipation requirements than many household appliances; in different projector application scenarios, the placement and installation form must also be changed accordingly (common installation and projection methods include front placement, front projection, ceiling installation, and inverted projection), and the difference in placement posture will also affect its heat dissipation, which can seriously lead to negative factors such as brightness attenuation and lens thermal drift. Utility Model Content

[0003] Based on this, it is necessary to provide a projector heat flow duct conversion structure and a projector to solve the problem of heat dissipation difficulty after the projector is installed.

[0004] In a first aspect, the present application provides a projector heat flow duct conversion structure, which includes: a heat dissipation component, two groups of air outlets and a plurality of air guide plates;

[0005] The heat dissipation component is located on the heat flow duct inside the projector;

[0006] Two sets of air outlets are located on the upper and lower surfaces of the projector to dissipate heat inside the projector;

[0007] The air guide plate is arranged inside the projector, covers the surface of the air outlet, and is movably connected with the upper surface and the lower surface of the projector.

[0008] Preferably, the air guide plate is movably connected to the upper surface or the lower surface of the projector via a buckle.

[0009] Preferably, the air guide plate rotates along the buckle when opened, and the rotation angle of the air guide plate is 30° to 50°.

[0010] Preferably, the air outlet further includes a dustproof component, and the dustproof component covers the surface of the air outlet.

[0011] Preferably, the dust-proof component is a filter.

[0012] Preferably, the heat dissipation component is a fan, and the fan is located on the side of the projector.

[0013] Preferably, the buckle of the air guide plate also includes a locking device.

[0014] In a second aspect, the present application provides a projector, which includes the projector heat flow duct conversion structure as described above.

[0015] Preferably, the projector further comprises a lens assembly, and the air outlet is located at one end of the projector; the heat dissipation assembly is arranged at the other end of the projector, and the lens assembly and the projector heat flow duct conversion structure are perpendicular to each other.

[0016] Preferably, the projector further comprises a hanging assembly, which is arranged on the upper surface or the lower surface of the projector and is used for hanging the projector.

[0017] The present application sets a projector heat flow duct conversion structure in the projector. After the projector is installed, the air guide plate can be opened and closed by gravity, and the air guide plate on the upper surface of the projector is always kept open. At the same time, when the heat dissipation mechanism dissipates heat, the cold air sinks and the hot air rises, so that the heat flow can always be dissipated from the top, thereby improving the heat dissipation effect of the projector and solving the problem of heat dissipation difficulty after the projector is installed.

[0022] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0023] It should be understood that the present invention can be implemented in different forms and should not be construed as being limited to the embodiments presented herein. On the contrary, providing these embodiments will make the disclosure thorough and complete and fully convey the scope of the present invention to those skilled in the art. In the accompanying drawings, the sizes and relative sizes of layers and regions may be exaggerated for clarity. The same reference numerals throughout represent the same elements.

[0024] It should be understood that when an element or layer is referred to as being "on, adjacent to, connected to or coupled to other elements or layers, it may be directly on, adjacent to, connected to or coupled to other elements or layers, or there may be intervening elements or layers. In contrast, when an element is referred to as being "directly on, directly adjacent to, directly connected to or directly coupled to other elements or layers, there may be no intervening elements or layers. It should be understood that, although the terms first, second, third, etc. may be used to describe various elements, components, regions, layers and / or parts, these elements, components, regions, layers and / or parts should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or part from another element, component, region, layer or part. Therefore, without departing from the teachings of the present invention, the first element, component, region, layer or part discussed below may be represented as a second element, component, region, layer or part.

[0025] Spatially relative terms such as "under," "below," "below," "under," "above," "above," etc., may be used herein for ease of description to describe the relationship of an element or feature shown in the figures to other elements or features. It should be understood that in addition to the orientations shown in the figures, the spatially relative terms are intended to include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, then the elements or features described as "under other elements" or "under" or "under" will be oriented as "on" the other elements or features. Therefore, the exemplary terms "under" and "under" may include both upper and lower orientations. The device may be oriented otherwise (rotated 90 degrees or other orientations) and the spatial descriptors used herein are interpreted accordingly.

[0026] The purpose of the terms used herein is only to describe specific embodiments and is not intended to be limiting of the present invention. When used herein, the singular forms "one", "an" and "said / the" are also intended to include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "consisting of" and / or "comprising", when used in this specification, determine the presence of the features, integers, steps, operations, elements and / or parts, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, parts and / or groups. When used herein, the term "and / or" includes any and all combinations of the relevant listed items.

[0027] like Figure 1 and Figure 2As shown, the projector includes a heat flow duct structure of the projector, and the heat flow duct structure includes a heat dissipation component 13, an air outlet 11 and a guide plate 14. The heat dissipation component 13 is located on the heat flow duct in the projector; two groups of air outlets 11 are located on the upper surface and the lower surface of the projector, and are used to extract the heat in the projector; the guide plate 14 is arranged inside the projector, covers the surface of the air outlet 11, and is movably connected with the upper surface and the lower surface of the projector. When the projector is installed, the guide plate on the upper surface sags due to gravity, so that the air outlet 11 is opened, so that the heat in the projector is discharged from the air outlet 11. At the same time, since the air outlet on the lower surface is still covered by the guide plate 14, dust is prevented from entering the projector. In addition, since the opened air outlet is the air outlet 11 on the upper surface when placed, and the hot air is usually on the upper side, and the cold air sinks to the lower side, the heat dissipation through the air outlet on the upper surface can improve the heat dissipation efficiency of the projector.

[0028] like Figure 3 As shown in FIG. 1 , it is a heat flow schematic diagram of the heat flow duct conversion structure of the projector when hoisted. In the hoisting condition, the air guide plate 14 on the lower surface of the absolute position is opened under the action of gravity, so the heat escapes from the upper part of the relative position, thereby reducing the heat in the projector and meeting the heat dissipation requirements of projectors in different installation positions. It is easy to operate and can achieve rapid heat dissipation only by gravity without other human actions.

[0029] In the projector heat flow duct conversion structure, the deflector plate is movably connected to the upper surface or lower surface of the projector through a buckle. The buckle connection method is simple and can meet the requirements of the deflector plate to close and open the air outlet. In addition, the deflector plate 14 is rotated by the buckle, and the rotation angle of the deflector plate is 30° to 50°. At this angle, the opening and closing of the deflector plate 14 will not affect the operation of other devices in the projector (such as light source optical machine, etc.), and at this angle, it avoids occupying too much space and affecting the layout of other devices in the projector. Its clamping angle can also ensure the heat dissipation efficiency and avoid the situation where the opening and closing angle is too small and the heat cannot be discharged. At the same time, the deflector plate also includes a locking device. After the deflector plate is controlled at a certain opening angle, the deflector plate is fixed by the locking device to avoid the shaking of the deflector plate during the operation of the projector.

[0030] In addition, in the projector of the present application, the air outlet further includes a dustproof component, which covers the surface of the air outlet. The dustproof component is a filter, which prevents dust from entering the projector.

[0031] In the projector of the present application, the heat dissipation component is a fan, and the fan is located on the side of the projector. The air outlet 11 of the projector is at one end of the projector; the heat dissipation component 13 is arranged at the other end of the projector 11, and the lens assembly 12 and the projector heat flow duct conversion structure are perpendicular to each other. Under this arrangement, the heat flow requirements of the entire projector can be met to achieve the purpose of heat dissipation.

[0032] It should be noted that the above embodiments illustrate the present application rather than limit the present application, and that those skilled in the art may design alternative embodiments without departing from the scope of the appended claims. In the claims, any reference symbol between brackets should not be constructed as a limitation on the claims. The word "comprising" does not exclude the presence of elements or steps not listed in the claims. The word "one" or "an" preceding an element does not exclude the presence of multiple such elements. The present application may be implemented with the aid of hardware including several different elements and with the aid of appropriately programmed computers. In a unit claim listing several on-board systems, several of these on-board systems may be embodied by the same hardware item. The use of the words first, second, and third, etc. does not indicate any order. These words may be interpreted as names.

[0033] The above is only a specific implementation method or description of a specific implementation method of the present application, and the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. The protection scope of the present application shall be based on the protection scope of the claims.
