Description

Technical Field

[0001] The utility model relates to a display system, in particular to a projection display system. Background Art

[0002] The heat dissipation structure is one of the important components in the projection display system. Components such as the light source, focus motor, and circuit board of the projection all require heat dissipation structures for heat dissipation, otherwise it will affect the service life of the projection.

[0003] Currently, projectors with small volumes are more favored by consumers because they are easy to install and carry. However, the small volume leads to a relatively crowded internal space, so it is difficult to install a split heat dissipation structure in a small-volume projector. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a projection display system, which solves the technical problems of difficult installation of the heat dissipation structure and poor heat dissipation effect in a small-volume projector.

[0005] To achieve the above purpose, the utility model provides a projection display system, including a housing and a heat dissipation component;

[0007] The heat dissipation component includes an integrally formed heat dissipation honeycomb plate and more than two fans. Both ends of the heat dissipation honeycomb plate are in contact with the inner side walls of the two sides of the housing respectively. One side of the heat dissipation honeycomb plate is in contact with the limiting columns. A connecting column is arranged on one side of the heat dissipation honeycomb plate, and the connecting column and the limiting column are connected by a first bolt. A fan is detachably connected to the other side of the heat dissipation honeycomb plate, and the fans are connected with limited positions.

[0008] Preferably, a limiting plate extends from the limiting column, and the limiting plate is in contact with the outer surface of the heat dissipation component.

[0009] Preferably, threaded holes are formed on the surface of the heat dissipation honeycomb plate where it is connected to the fan, through holes are formed on the fan, a second bolt is arranged in the through hole, the head of the second bolt abuts against the fan, and the second bolt is in threaded connection with the threaded hole.

[0010] Preferably, the fan includes a first fan and a second fan. A limiting groove is formed on one side of the second fan, and a limiting block is fixedly arranged on one side of the first fan, and the limiting block is arranged in the limiting groove.

[0011] Preferably, a connecting column is fixedly arranged at one end of the first fan, and the connecting column is connected to the limiting column by a first bolt;

[0012] A connecting column is fixedly arranged at one end of the second fan, and the connecting column is connected to the limiting column by a first bolt.

[0013] The beneficial effects obtained by the utility model are as follows:

[0014] The utility model reserves an installation space for the heat dissipation component by arranging the limit posts, which is convenient for the installation of the heat dissipation component; the heat dissipation honeycomb plate in the heat dissipation component is integrally formed and does not require assembly, so the installation is more convenient; the fans are connected with each other in a limited way, so the fans can be first spliced together and then installed on the heat dissipation honeycomb plate, that is, the heat dissipation component can be installed as a whole outside the shell and then installed in the shell, and the installation is more convenient.

[0020] The following clearly and completely describes the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model, so the present utility model is not limited by the specific embodiments disclosed below.

[0021] As Figures 1 - 3 shown, the present utility model discloses a projection display system, including a shell 1, a heat dissipation component 2, an optical engine, a lens, etc. The optical engine and the lens are not shown in the figure. Since the optical engine and the lens are relatively conventional prior arts, they will not be described in detail.

[0022] As Figure 3As shown, four limiting posts 12 are fixedly arranged inside the housing 1. The limiting posts 12 all extend in the vertical direction. The area between these four limiting posts 12 is used to install the heat dissipation component 2. In this embodiment, the heat dissipation component 2 includes an integrally formed heat dissipation honeycomb plate 21 and two fans 22. As Figure 1 , Figure 3 shown, both ends of the heat dissipation honeycomb plate 21 are abutted against two opposite inner side walls of the housing 1 respectively. One surface of the heat dissipation honeycomb plate 21 abuts against the two limiting posts 12. Two connecting posts 211 are fixedly arranged on this surface of the heat dissipation honeycomb plate 21. After installation, the connecting posts 211 are located directly above the limiting posts 12. The limiting posts 12 and the connecting posts 211 are connected into one body by the first bolts 3, so as to fix the heat dissipation honeycomb plate 21 on the housing 1.

[0023] As Figure 2 shown, the other surface of the heat dissipation honeycomb plate 21 is used to install the fans 22. The two fans 22 are connected in a limited way. Through holes are respectively formed in the top edge and the bottom edge of the fan 22. The heat dissipation honeycomb plate 21 is provided with threaded holes corresponding to the through holes. During use, the second bolts 4 are inserted into the through holes, and then the second bolts 4 are screwed into the threaded holes until the heads of the second bolts 4 abut against the fans 22, so as to realize the detachable connection between the fans 22 and the heat dissipation honeycomb plate 21.

[0024] For the convenience of description, the two fans 22 are divided into a first fan 221 and a second fan 222. Taking Figure 3 as an example, connecting posts 211 are respectively fixedly arranged on the right side of the first fan 221 and the left side of the second fan 222. These two connecting posts 211 are respectively detachably connected to the corresponding limiting posts 12 by the first bolts 3. A limiting block 2211 is fixedly arranged on the left side surface of the first fan 221, and a limiting groove 2221 is formed in the right side surface of the second fan 222. The limiting block 2211 is inserted into the limiting groove 2221. Thus, the limiting connection between the first fan 221 and the second fan 222 is realized, that is, the limiting groove 2221 and the limiting block 2211 are respectively arranged on the adjacent surfaces of the two fans 22.

[0025] Obviously, when the heat dissipation honeycomb plate 21 is relatively large and more fans 22 are needed for heat dissipation, the fans 22 can also be limitedly connected through the limiting blocks 2211 and the limiting grooves 2221, which will not be elaborated here.

[0026] To further improve the clamping stability of the limiting posts 12 on the heat dissipation component 2, a limiting plate 121 extends from the side of the limiting posts 12, and the limiting plate 121 abuts against the outer surface of the heat dissipation component 2.

[0027] During use, first insert the limit block 2211 into the limit slot 2221 to connect the first fan 221 and the second fan 222 into a whole. Subsequently, use the second bolt 4 to fix the first fan 221 and the second fan 222 on the heat dissipation honeycomb plate 21. At this time, the heat dissipation honeycomb plate 21 and the fan 22 are spliced into one body, that is, the heat dissipation component 2 is assembled. Insert the assembled heat dissipation component 2 between the four limit posts 12, and then use the first bolt 3 to fix the heat dissipation component 2 on the limit posts 12, thus completing the installation of the heat dissipation component 2.

[0028] To improve the heat dissipation performance, the housing 1 can be provided with ventilation openings, which will not be described here.

[0029] Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
