A projector is a device that can project images or videos onto a curtain or a wall, and can be connected to electronic devices such as a computer, a mobile phone, a DVD, a game machine, etc. through different interfaces to play corresponding video signals. The projector comprises a shell, and an electronic component and a circuit board which are arranged in the shell, wherein the electronic component comprises functional components such as a projection optical machine, a sound box or a radiator, and the circuit board is electrically connected with the electronic component so as to transmit driving or control signals to the electronic component. The circuit board is usually mounted on a metal fixing plate, and the fixing plate is connected to one or more electronic components, so as to fix the circuit board and the internal structure of the projector relatively. However, the fixing plate in the current projector is generally in a simple flat shape, and if the fixing plate is mounted on an electronic component with an irregular appearance, such as a projector with a complicated appearance, the fixing plate and the electronic component can occupy more space in the mounting direction and cannot be tightly arranged, so that the fixing plate and the mounted electronic component can occupy too much unused space in the projector, the utilization rate of the internal space of the projector is reduced, and the volume of the projector is difficult to further compress.
To solve the above problem, the present application provides a projection apparatus. In the embodiment of the present invention, please refer to fig. 1, fig. 2 and fig. 5, in which fig. 1 is a schematic structural diagram of an embodiment of a middle fixing frame 20 of the present invention; fig. 2 is a schematic view of an assembly structure of the middle fixing frame 20 and the circuit board 30 according to the present invention; fig. 5 is a schematic view of an assembly structure of the middle fixing frame 20 and the electronic component 10 according to the present invention. The projection device includes: a housing (not shown); an electronic component 10 mounted in the housing; the fixing frame 20 comprises a fixing plate 21, an extending part 22 and a mounting part 23, wherein the fixing plate 21 is provided with a mounting side 213, one end of the extending part 22 is connected to the edge area of the fixing plate 21, the other end of the extending part extends towards the mounting side 213 and the direction far away from the fixing plate 21, and the mounting part 23 is connected to one end of the extending part 22 far away from the fixing plate 21; the electronic component 10 is mounted on one side of the mounting part 23 close to the fixing plate 21; a circuit board 30, the circuit board 30 being mounted to the fixing plate 21 at the mounting side 213, and the circuit board 30 being electrically connectable with the electronic component 10. It should be noted that the peripheral edge of the fixing plate 21 and the area of the plate surface near the peripheral edge can be regarded as the edge area in the present application.
In this embodiment, specifically, the housing forms an integral appearance structure of the projection apparatus, a mounting cavity is formed inside the housing, and the electronic component 10, the circuit board 30 and the fixing frame 20 are mounted in the housing. The electronic component 10 includes functional components such as a projector, a sound box, and a heat sink, and the circuit board 30 may be electrically connected to the electronic component 10 to serve as a main control board for transmitting driving signals and control signals to the electronic component 10.
The fixing frame 20 may be integrally formed of a metal material, such as aluminum, to have sufficient structural strength. The fixing plate 21 may be a flat plate, and the edge of the fixing plate 21 may form a local concave-convex structure area in the extending direction of the plate surface, which is not limited herein. One side of the board surface of the fixing plate 21 is used for mounting the circuit board 30, and the extending portion 22 may be connected to the board surface of the fixing plate 21, or may be connected to the side of the fixing plate 21, which is not limited herein, only needs to satisfy that the extending portion 22 is connected to the edge area of the fixing plate 21, and at this time, the influence of the extending portion 22 on the mounting position of the circuit board 30 can be avoided as much as possible.
The fixed plate 21 has a mounting surface, the mounting side 213 is the side facing the mounting surface, and the circuit board 30 is mounted on the fixed plate 21 on the mounting side 213; the extension 22 extends toward the mounting side 213, i.e., away from the fixing plate 21, so that the mounting portion 23 connected to the extension 22 is not flush with the fixing plate 21. It should be noted that the mounting portion 23 and the fixed plate 21 are not on the same plane, and the projection of the mounting portion 23 and the fixed plate 21 is shifted in the normal direction of the fixed plate 21, that is, they are not opposed to each other. Alternatively, it can be understood that the orthographic projections of the mounting portion 23 and the fixing plate 21 on a plane on which the fixing plate 21 is located do not overlap each other. The electronic component 10 is mounted on the side of the mounting portion 23 close to the fixing plate 21, and the circuit board 30 is mounted on the side of the fixing plate 21 close to the mounting portion 23, so that the arrangement relationship among the electronic component 10, the fixing frame 20 and the circuit board 30 can be more compact.
In the technical solution of the projection apparatus of the present invention, the fixing plate 21 and the mounting portion 23 of the fixing frame 20 are staggered by the extending portion 22, that is, the fixing plate 21 and the mounting portion 23 are not located on the same plane; after the side of the mounting portion 23 close to the fixing plate 21 is connected to the outer wall of the electronic component 10, the fixing plate 21 can sink toward the electronic component 10 relative to the mounting portion 23, so that the distance between the fixing plate 21 and the electronic component 10 can be reduced, the assembly structure of the fixing frame 20 and the electronic component 10 can be more compact, the invalid occupied space of the fixing frame 20 and the electronic component 10 can be reduced, and the utilization rate of the internal space of the projection apparatus can be improved. In particular, when the mounting portion 23 is mounted on the top of the electronic component 10 on a side close to the fixing plate 21, it may be advantageous to achieve a high degree of compression of the projection apparatus.
In some embodiments, the extending direction of the extending portion 22 may be a right angle or an obtuse angle with the plate surface of the fixing plate 21. In practical applications, as shown in fig. 5, the electronic component 10 may be a projection engine, the mounting portion 23 is mounted on the top of the projection engine, the projection engine has a complex shape and structure, and the top of the projection engine has a sinking plane and a protruding plane protruding from the sinking plane, and the sinking plane and the protruding plane are connected by an inclined wall. In addition to the projector light, the electronic component 10 may also be a sound box or a heat sink.
For example, as shown in fig. 1 and fig. 5, the extension portion 22 extends obliquely toward the mounting side 213 and away from the fixing plate 21, that is, the extending direction of the extension portion 22 forms an obtuse angle with the plate surface of the fixing plate 21, so that after the mounting portion 23 is mounted on the projecting surface of the projector, the extension portion 22 can be opposite to or abutted against the inclined wall to reduce the mutual interference between the extension portion 22 and the inclined wall, so that the fixing plate 21 can smoothly sink to the sinking surface relative to the mounting portion 23, and the overall mounting structure of the fixing frame 20 and the electronic component 10 is more compact. Specifically, the fixing frame 20 is located between the electronic component 10 and the top wall of the housing to prevent the circuit board 30 from being pressed by other structures inside the projection device, thereby protecting the circuit board 30.
Referring to fig. 2 and 3, fig. 3 is a top view of an assembly structure of the middle fixing frame 20 and the circuit board 30 according to the present invention. The circuit board 30 is provided with a wiring port 31 and a wiring harness 40 connected to the wiring port 31, and the wiring harness 40 is used for connecting with the electronic component 10 to electrically connect the circuit board 30 and the electronic component 10. The electronic component 10 connected to the wire harness 40 may be the electronic component 10 mounted on the mounting portion 23, or may be another electronic component 10, which is not limited herein.
Referring to fig. 4 and fig. 6 together, fig. 4 is a side view of an assembly structure of the middle fixing frame 20 and the circuit board 30 of the present invention; fig. 6 is a plan view of an assembly structure of the electronic component 10 and the middle fixing frame 20 according to the present invention. The wiring port 31 is disposed at an edge of the circuit board 30 close to the mounting portion 23 and faces at least one of the extension portion 22 and the mounting portion 23; at least one end of the mounting portion 23 extends outward to form a crimping portion 231 in a first direction perpendicular to an extending direction of the extending portion 22 and perpendicular to an orientation of the wire connection port 31; the wire pressing part 231 limits the wire harness 40 at one side of the mounting part 23 close to the electronic component 10, for example, the bottom of the wire pressing part 231 is pressed against the wire harness 40, so as to prevent the wire harness 40 from bouncing and covering to one side of the mounting part 23 away from the electronic component 10, and further help prevent the wire harness 40 from interfering with the assembly between the fixing frame 20 and the electronic component 10.
It can be understood that the connection port 31 is adjacent to the edge region of the fixing plate 21 to which the extension portion 22 is connected, and the extension direction of the wire harness 40 in the portion adjacent to the connection port 31 is the same as the orientation of the connection port 31, so that the portion of the wire harness 40 extending out of the edge of the fixing plate 21 can be limited by the wire pressing portion 231, and the wire pressing portion 231 can limit the wire harness 40 to be bundled, and the wire harness 40 on the circuit board 30 can be prevented from being disordered. The crimping portion 231 and the mounting portion 23 may be integrally formed or may be separately connected, and is not limited herein.
The crimping portion 231 may be formed only at one end of the mounting portion 23, or may be formed at both ends of the mounting portion 23. For example, as shown in fig. 2 and 3, in the first direction, two opposite ends of the mounting portion 23 extend outward to form the line pressing portions 231; the circuit board 30 is provided with at least two wiring ports 31, and each of the wire crimping portions 231 is faced by at least one of the wiring ports 31. Each of the wire connection ports 31 of the circuit board 30 may be connected with a wire harness 40, and for the wire connection port 31 facing the two crimping portions 231, the wire harness 40 connected to the wire connection port 31 may be restricted by the two crimping portions 231 to improve the limiting and bundling effect on the wire harness 40.
The wiring port 31 may be disposed on a surface of the circuit board 30 facing the fixing plate 21, or may be disposed on a surface of the circuit board 30 away from the fixing plate 21; if the connection port 31 is provided on the surface of the circuit board 30 facing the fixing plate 21, the connection port 31 may be pressed and heat dissipation from the connection port 31 may be not facilitated. For example, referring to fig. 4 and 7, fig. 7 is a partial side view of the assembly of the electronic component 10 and the fixing frame 20 according to the present invention. The wiring port 31 is arranged on one side of the circuit board 30 far away from the fixing plate 21; in the direction of the fixing plate 21 toward the mounting side 213, the minimum height of the mounting portion 23 is smaller than the maximum height of the connection port 31, and the wire pressing portion 231 extending from the mounting portion 23 can effectively press the wire harness 40 connected to the connection port 31, thereby preventing the wire harness 40 from covering the top of the mounting portion 23. The protection effect and the heat dissipation effect on the wiring port 31 can be improved by arranging the wiring port 31 on the side of the circuit board 30 away from the fixing plate 21. The minimum height of the mounting portion 23 is smaller than the maximum height of the port, so as to ensure that the mounting portion 23 can effectively limit the position of the wire harness 40, prevent the wire harness from interfering with the assembly between the mounting portion 23 and the electronic component 10, and reduce the overall thickness of the fixing frame 20.
For example, as shown in fig. 7, the electronic component 10 is convexly provided with a fixing post 11, a fixing hole is formed at a tail end of the fixing post 11, the mounting portion 23 is lapped on the tail end of the fixing post 11, a mounting hole 233 is formed in the mounting portion 23, and the mounting hole 233 is matched with the fixing hole through a fastener. Specifically, the fastener may be a screw that passes through the mounting hole 233 and is fixedly connected to the fixing hole, thereby achieving fixation between the mounting portion 23 and the electronic component 10. In combination with the above-mentioned embodiment of the wire pressing portion 231, the fixing post 11 can support the mounting portion 23, so that a sufficient trace space is provided between the wire pressing portion 231 and the electronic component 10. When the mounting portion 23 is fixed, a fastener is disposed from a side of the mounting portion 23 away from the fastening post 11, and the wire pressing portion 231 can limit the wire harness 40 at a side of the mounting portion 23 facing the fastening post 11, so that the wire harness 40 can be prevented from obstructing the process of disposing the fastener, and the assembly efficiency of the mounting portion 23 and the electronic component 10 can be improved.
The holder 20 may or may not be attached to the inner wall of the housing. Illustratively, the fixing plate 21 is fixedly connected to the inner wall of the housing, and thus, the fixing frame 20 is connected to both the electronic component 10 and the housing, so that the electronic component 10 and the housing can be fixed relative to each other, thereby reducing vibration of the electronic component 10 and improving the mounting stability of the electronic component 10. In addition, the fixing plate 21 is coupled to the housing to prevent the housing from being crushed, thereby improving structural stability of the housing.
The crimping portion 231 may have a straight plate shape, or may have a bent or curved shape. For example, please refer to fig. 8, fig. 8 is a schematic structural diagram of another embodiment of the middle fixing frame 20 of the present invention. In the first direction, an end of the wire pressing portion 231, which is away from the extending portion 22, is bent in a direction to approach the electronic component 10, so that the wire harness 40 can be prevented from coming off the wire pressing portion 231 in the first direction.
For example, please refer to fig. 9, fig. 9 is a schematic structural diagram of another embodiment of the middle fixing frame 20 of the present invention. At least one side of the extension portion 22 in the first direction is provided with a wire avoiding opening 221, and the wire avoiding opening 221 can avoid the position of the wire harness 40, so that more routing space can be provided for the wire harness 40. In one embodiment, the wiring ports 31 on the circuit board 30 face the wire escape ports 221.
For example, as shown in fig. 2, a supporting pillar 211 is protruded from a surface of the fixing plate 21 facing the circuit board 30, and the circuit board 30 is fixed to the supporting pillar 211 to form a heat dissipation space between the circuit board 30 and the fixing plate 21. The number of the supporting columns 211 is plural, and the supporting columns 211 are distributed on one surface of the mounting side 213 of the fixing plate 21, so as to improve the supporting stability of the circuit board 30. The heat dissipation space can facilitate heat dissipation of the circuit board 30 and prevent heat absorbed by the fixing plate 21 from being transferred to the circuit board 30.
For example, as shown in fig. 7, a contact portion 212 is formed on a surface of the fixing plate 21 facing the circuit board 30, and the contact portion 212 protrudes from a surface of the fixing plate 21; a chip 32 is disposed on a surface of the circuit board 30 facing the fixing plate 21, and the chip 32 abuts against the contact portion 212. The heat generated by the chip 32 during operation can be transmitted to the fixing plate 21, the extending portion 22 and the mounting portion 23 through the contact portion 212, and the extending portion 22 and the mounting portion 23 can increase the heat dissipation area of the fixing plate 21, so as to improve the heat dissipation efficiency of the chip 32.
The above is only the optional embodiment of the present invention, and not the scope of the present invention is limited thereby, all the equivalent structure changes made by the contents of the specification and the drawings are utilized under the inventive concept of the present invention, or the direct/indirect application in other related technical fields is included in the patent protection scope of the present invention.
