With the rapid development of projection technology, the current projector has already had an image correction function, and the projector can automatically correct the projection deviation through the image correction function. In practice, a conventional projector generally shoots a currently projected picture through a camera, then analyzes and judges whether the currently projected picture is normal, and performs corresponding adjustment. However, in order to completely capture a projection image, a camera of a conventional projector is generally provided with a large light-transmitting hole on a housing, which affects the appearance of the projector.
In view of this, this application proposes a projector, and the camera that aims at solving traditional projector is in order to shoot projection picture completely, and the general great that sets up of light passing hole on the casing compares the problem that influences the outward appearance of projector. Fig. 1 to 7 are schematic structural diagrams of an embodiment of a projector according to the present application.
Referring to fig. 1 to 4, a projector 100 according to the present application includes a housing 1 and a camera assembly 2. The inside of the shell 1 is provided with an installation cavity, and the shell 1 is provided with a plurality of heat dissipation holes 11 and a light passing hole 12 which are communicated with the installation cavity. The plurality of heat dissipation holes 11 are arranged around the light passing hole 12, and the plurality of heat dissipation holes 11 extend along the first direction M, and the light passing hole 12 is gradually widened from inside to outside. The camera assembly 2 comprises a lens arranged on one side of the light through hole 12 away from the mounting cavity and a camera 23 arranged in the mounting cavity, wherein the camera 23 is arranged opposite to the light through hole 12 along the first direction M.
In this application, the first direction M is a relative direction, and the first direction M may be the extending direction of the heat dissipation hole 11.
In the technical scheme of the application, through setting up a plurality of louvres 11 on the casing 1 of projector 100 to by a plurality of louvres 11 around the light hole 12, thereby make the light hole 12 can not pay attention to very much, increased the disguise of lens 21 and the aesthetic property of whole projector. In addition, the light-passing holes 12 are gradually widened from inside to outside, so that the radial dimension of the light-passing holes 12 is gradually enlarged from inside to outside, which makes the camera 23 have a more excellent shooting view angle, and a projection picture can be completely shot.
The light-passing hole 12 is not a conventional cylindrical hole, which makes it difficult for the user to observe a large circular hole from the outside, but only the shape of the port of the light-passing hole 12 near the side of the installation cavity, making it difficult for the light-passing hole 12 to be easily found. Specifically, the size of the port of the light-passing hole 12 near the side of the installation cavity is smaller, and the size of the port near the outside is larger, so that when a user observes the light-passing hole 12 outside the casing 1, the light-passing hole 12 comprises a circular area in the middle and an annular area surrounding the periphery of the circular area, and the light-passing hole 12 can be easily confused in the plurality of heat dissipation holes 11, and is not easy to be found by the user during use. The light through holes 12 of the projector 100 can be easily mixed among the plurality of heat dissipation holes 11, so that visual impact to a user is avoided, and the attractiveness of the projector 100 is improved.
Referring to fig. 3, in some embodiments, the light-passing hole 12 includes a first port near the mounting cavity and a second port far from the mounting cavity, and the first port has the same shape and size as the mouth of the heat-dissipating hole 11.
The first port and the second port on the lens 21 can allow light to pass through, so that the camera 23 of the camera assembly 2 can complete shooting of the projection image by means of the first port. It should be noted that, the radial dimension of the second port of the light-passing hole 12 is larger than that of the first port, so that the camera 23 can obtain light within a larger range by virtue of the light-passing hole 12, so that the camera 23 can shoot a complete projection picture conveniently.
It should be noted that the first port of the light-passing hole 12 has a smaller size, and the second port has a larger size, so that the light-passing hole 12 includes a circular region in the middle and an annular region surrounding the outer periphery of the circular region when the user views the light-passing hole 12 outside the housing 1. While the first port of the lens 21 is the same shape and size as the heat sink 11, this makes it more difficult for a user to discern the circular area in the plurality of heat sinks 11, thereby further helping to hide the light passing holes 12.
In some embodiments, the lens 21 includes a light-transmitting portion 211 in a middle portion thereof, the light-transmitting portion 211 is disposed opposite to the second port along the first direction M, and an area of the light-transmitting portion 211 is greater than or equal to an area of the second port and is the same as the shape and size of the second port.
The light-transmitting portion 211 can allow external light to enter the light-transmitting hole 12 and enter the camera 23 through the light-transmitting hole 12. In this application, the area of the light-transmitting portion 211 is greater than or equal to the area of the second port, so that the light-transmitting portion 211 does not prevent any light from entering the light-transmitting hole 12, and the shooting performance of the camera 23 is ensured. It should be noted that, the size of the second port is larger than that of the first port, so the light receiving capability of the light passing hole 12 is relatively strong, and the camera 23 can take a complete projection picture.
In some embodiments, the light-transmitting portion 211 is the same shape and size as the second port, such that the light-transmitting portion 211 does not prevent any light from entering the light-transmitting aperture 12.
Specifically, the lens 21 needs to be at least partially in contact with the housing 1 at the time of installation, and the portion of the lens 21 in contact with the housing 1 cannot be disposed opposite to the light-passing hole 12 in the first direction M, so that the portion of the lens 21 in contact with the housing 1 cannot receive light, and the portion of the lens 21 in contact with the housing 1 also amplifies the difference between the lens 21 and the housing 1, resulting in the lens 21 being more easily found by the user. Thus, in some embodiments, the lens 21 further includes a coating portion surrounding the light-transmitting portion.
The coating portion, which is the portion of the lens in contact with the housing 1 as described above, keeps the color of the coating portion consistent with that of the housing 1, making the coating portion difficult to distinguish from the housing 1, thus increasing the concealment of the lens 21, making it difficult for the user to easily find the lens 21 when in use.
Referring to fig. 6 to 7, in some embodiments, the camera module 2 further includes a camera circuit board 22 disposed on an inner wall of the housing 1, and the camera circuit board 22 is used for mounting the camera 23. The direction of the camera circuit board 22 is set at an angle to the first direction M, so that the direction of the camera 23 is set at a preset angle to the first direction M.
In practical application, in order to facilitate the projector 100 to be directly placed on a desktop for projection, the lens of the projector 100 is usually set off-axis (Offset), so that the bottom edge of the projection screen and the lens of the projector 100 are in the same horizontal plane, and therefore, the orientation of the camera 23 needs to be set in a deflection manner to capture the complete projection screen. Therefore, in some embodiments, the direction of the camera circuit board 22 is set at an angle to the first direction M, so that the direction of the camera 23 is set at a preset angle to the first direction M, so that the camera 23 can capture a complete projection image.
Referring to fig. 6 and 7, in some embodiments, the predetermined angle is a, wherein: a is more than or equal to 0 degree and less than or equal to 13 degrees. Some projectors 100 do not require off-axis placement, so that the camera 23 may be positioned at an angle of 0 ° without being skewed for a particular application. In practice, the preset angle of the required deflection of the camera 23 is not too large, otherwise the photographing angle of the camera 23 may be deteriorated instead. The inventor of the present application repeatedly tests to obtain that the preset angle required by the camera 23 cannot be larger than 13 ° generally, and the camera 23 can more stably shoot the projection image of the projector 100 in a deflection arrangement.
In some embodiments, the inner wall of the housing 1 is provided with a mounting portion 13 disposed opposite to the image pickup circuit board 22 along the first direction M, the mounting portion 13 is provided with a plurality of mounting posts 131 extending along the first direction M, and each mounting post 131 is provided with a threaded hole; the imaging circuit board 22 is provided with a plurality of mounting holes in one-to-one correspondence with the screw holes to be connected to the mounting portion 13.
The plurality of mounting posts 131 includes a first mounting post 131a and a second mounting post 131b disposed at intervals along the second direction N, and a dimension of the first mounting post 131a in the first direction M is greater than a dimension of the second mounting post 131b in the first direction M, so that a direction of the camera 23 disposed on the camera circuit board 22 is set at a preset angle with the first direction M. Wherein the first direction M and the second direction N are perpendicular to each other.
In this application, the second direction N is another opposite direction, and the second direction N may be set as an opposite direction of the first mounting post 131a and the second mounting post 131b, and the first direction M and the second direction N are perpendicular to each other.
In some conventional projectors 100, a mounting board is generally provided on the housing 1, and the camera circuit board 22 is mounted on the additional mounting board, which definitely occupies a large space in the mounting cavity. In some embodiments of the present application, the housing 1 is provided with the mounting portion 13, and the mounting portion 13 is actually a part of the housing 1, and the plurality of mounting posts 131 on the mounting portion 13 are detachably connected with the camera circuit board 22, so that the camera circuit board 22 is directly fixed on the housing 1, and the space occupying the mounting cavity is reduced.
In addition, the image capturing circuit board 22 is connected to the first mounting post 131a and the second mounting post 131b, and the lengths of the first mounting post 131a and the second mounting post 131b in the first direction M are different, so that the image capturing circuit board 22 is inclined when the image capturing circuit board 22 abuts against the first mounting post 131a and the second mounting post 131 b. Therefore, in a specific design, by setting the lengths of the first mounting post 131a and the second mounting post 131b, the direction of the camera circuit board 22 and the first direction M can be set at an angle, and the direction of the camera 23 mounted on the camera circuit board 22 at this time and the first direction M can be set at a preset angle. When the orientation of the camera 23 is set at a preset angle with the first direction M, the camera 23 can stably capture a complete projection image, so that the projector 100 accurately corrects the projection angle.
Referring to fig. 2 to 4, in some embodiments, the heat dissipation holes 11 disposed opposite to the mounting portion 13 along the first direction M among the plurality of heat dissipation holes 11 are configured as blind holes. Since a plurality of mounting posts 131 are required to be provided on the mounting portion 13, the heat dissipation holes 11 provided opposite to the mounting portion 13 in the first direction M may overlap the mounting portion 13. When the user is using the projector 100, the user may notice the mounting portion 13 on the other side of the heat dissipation hole 11, which also reduces the aesthetic appearance of the projector 100. Therefore, the heat dissipation hole 11 opposite to the mounting portion 13 along the first direction M may be a blind hole, so that the user cannot notice the mounting portion 13 on the other side of the heat dissipation hole 11, thereby increasing the concealment of the mounting portion 13 and ensuring the aesthetic property of the projector 100.
Referring to fig. 5 to 7, in some embodiments, the projector 100 further includes a heat sink 3 disposed in the mounting cavity, and a receiving groove 31 is disposed on a side of the heat sink 3 adjacent to the camera module 2, and the camera module 2 is at least partially received in the receiving groove 31.
The plurality of heat dissipation holes 11 are disposed around the light passing hole 12, and the lens 21 of the camera module 2 is mounted on the light passing hole 12, so that the camera module 2 and the plurality of heat dissipation holes 11 are disposed substantially opposite to each other along the axial direction of the heat dissipation holes 11. In addition, the plurality of heat dissipation holes 11 mainly function to perform gas exchange between the inside and the outside of the installation cavity, so that the hot air conveyed by the heat sink 3 can be smoothly blown out, and therefore, the heat sink 3 and the plurality of heat dissipation holes 11 are arranged opposite to each other along the axial direction of the heat dissipation holes 11. Specifically, the camera module 2 is actually disposed between the housing 1 and the plurality of heat dissipation holes 11.
In fact, the radiator 3 is further provided with sealing foam, and the sealing foam can seal between the radiator 3 and the shell 1, so that the radiator 3 can radiate heat conveniently. The volume of the camera module 2 is much smaller than that of the radiator 3, so that the sealing foam surface can be practically enclosed around the camera module 2, thereby helping the camera module 2 to be hidden.
Referring to fig. 6 to 7, specifically, a receiving groove 31 is formed on a side of the heat sink 3 close to the camera module 2, and the camera module 2 is at least partially received in the receiving groove 31, so that the camera module 2 is more compact to mount, and the space utilization of the mounting cavity is increased.
In some embodiments, the projector 100 further includes an axial flow fan 4 mounted in the mounting cavity, the axial flow fan 4 being disposed opposite the lens 21 along the first direction M at an axial center thereof. The axial center of the axial fan 4 is a weak wind area, and the axial center of the axial fan 4 and the lens 21 are arranged opposite to each other along the first direction M, so that the influence of the camera assembly 2 on the heat dissipation effect of the axial fan 4 is small, and the normal heat dissipation of the projector 100 is not influenced.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples only represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the claims. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application. Accordingly, the scope of protection of the present application is to be determined by the claims appended hereto.
