Detailed Description
The following detailed description of embodiments of the utility model is, therefore, to be taken in conjunction with the accompanying drawings, and it is to be understood that the scope of the utility model is not limited to the specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the term "comprise" or variations thereof such as "comprises" or "comprising", etc. will be understood to include the stated element or component without excluding other elements or components.
As shown in fig. 1 to 6, an LED-based visible light communication system emitting device according to an embodiment of the present utility model includes a housing 1, a first mounting base 6 is disposed on the housing 1, and a plurality of first heat dissipation holes 11 are formed in the first mounting base 6.
Specifically, a radiator fan is disposed below the first mounting base 6, and air can enter the housing 1 through the first radiator hole 11 by the radiator fan, so that air circulates, and then the emission module 2 in the housing 1 radiates heat. The first mounting base 6 is fixedly connected with a first connecting block 8, and a first mounting hole 7 is formed in the first connecting block 8.
Referring to fig. 1 and 2, when limited to the installation environment, the first installation base 6 can be fixedly connected under the fixing plate 41 by connecting bolts between the first installation holes 7 and the fixing holes 411, thereby fixing the entire emitting device. However, at this time, the fixing hole 411 will cover the first heat dissipation hole 11 formed on the first mounting base 6, and even if there is a heat dissipation fan, air still cannot enter the housing 1 through the first heat dissipation hole 11, or only a small amount of air can enter the housing 1 through the first heat dissipation hole 11, so as to affect heat dissipation of the emission module 2.
The top of first installation base 6 is provided with second installation base 21, is provided with fixed subassembly 31 between second installation base 21 and the first installation base 6, has the clearance between first installation base 6 and the second installation base 21, fixedly connected with fixed plate 41 on the second installation base 21.
Specifically, a gap can be provided between the first mounting base 6 and the second mounting base 21 by the fixing member 31. That is, when the second mounting base 21 is fixedly connected to the lower end surface of the fixing plate 41, air can still pass through the first heat dissipation hole 11 from the space above the first heat dissipation hole 11 to enter the housing 1, so as to dissipate heat of the transmitting module 2 in the housing 1.
Referring to fig. 4 and 5, the first mounting base 6 has a threaded hole 61 formed therein, and the fixing assembly 31 includes a threaded post 311 screwed into the threaded hole 61. The threaded column 311 is fixedly connected with a sleeve 312 near one end of the second mounting base 21, and a limiting hole 214 matched with the sleeve 312 is formed in the second mounting base 21. An internal thread is formed in the sleeve 312, a fixing bolt 313 is connected with the internal thread of the sleeve 312, and a limit groove 215 matched with the fixing bolt 313 is formed in the second mounting base 21.
Specifically, the threaded post 311 can be screwed into the threaded hole 61, the diameter of the limiting hole 214 is smaller than the diameter of the threaded post 311, and the threaded post 311 can support the second mounting base 21. The sleeve 312 can be directly inserted into the limiting hole 214 to limit the second mounting base 21, and the second mounting base 21 can be fixedly connected to the threaded column 311 by tightening the fixing bolt 313. So that a gap exists between the second mounting base 21 and the first mounting base 6.
The fixing bolt 313 does not protrude out of the limit groove 215, and a tightening groove is formed in the fixing bolt 313. Tightening or loosening of the fixing bolt 313 is facilitated by tightening the slot.
A plurality of second connecting blocks 211 are fixedly connected to the second mounting base 21, second mounting holes 212 are formed in the second connecting blocks 211, and fixing holes 411 matched with the second mounting holes 212 are formed in the fixing plates 41. The second mounting base 21 can be fixedly coupled to the fixing plate 41 through the second mounting hole 212 and the fixing hole 411.
A plurality of second heat dissipation holes 213 are formed in the second mounting base 21, the second connection block 211 is located above the first mounting base 6, and a gap is formed between the second mounting base 21 and the fixing plate 41. That is, the second heat dissipation holes 213 allow air to enter the housing 1 from a plurality of directions through the first heat dissipation holes 11, thereby increasing the circulation of air and improving the heat dissipation effect. The second heat dissipation holes 213 are staggered with the first heat dissipation holes 11.
Referring to fig. 6, specifically, when the fixing of the transmitting device is not required, the second mounting base 21 may be detached from the fixing plate 41, and then the screw column 311 is rotated to move the screw column 311 toward the lower side of the first mounting base 6 until the upper end surface of the screw column 311 is flush with the upper end surface of the first mounting base 6.
At this time, the second mounting base 21 can be turned over and fixed on the first mounting base 6, and the fixing bolts 313 do not protrude from the limiting grooves 215, i.e. do not interfere with the second mounting base 21 to be attached to the first mounting base 6. Since the second heat dissipation holes 213 are staggered with the first heat dissipation holes 11, dust and water are not easy to enter the housing 1 through the first heat dissipation holes 11 at this time, and damage is caused to the emission module 2 in the housing 1.
The lower end face of the threaded column 311 is not in contact with the transmitting module 2, so that the transmitting module 2 is prevented from being touched by mistake, and the upper face and the side face of the transmitting device can be protected through the second mounting base 21 and the second connecting block 211.
Preferably, a guard rail may be disposed between the plurality of second connection blocks 211, so as to further enhance the protection of the transmitting device, so that the transmitting device is not easily impacted by external force. Meanwhile, the second mounting base 21 and the second connecting block 211 can save space to the greatest extent, and are convenient to transport along with the launching device.
In use, referring to fig. 1-6, when the launching device is to be secured, the threaded post 311 is threaded into the threaded bore 61 such that the sleeve 312 is positioned within the spacing bore 214. The second mounting base 21 can be fixed on the first mounting base 6 by tightening the fixing bolt 313 in the sleeve 312, and the second connecting block 211 is located above the second mounting base 21.
Since the threaded post 311 has a length, i.e. there is a gap between the second mounting base 21 and the first mounting base 6. The second mounting base 21 is then fixed to the fixing plate 41 through the second mounting holes 212 and the fixing holes 411. Since the second connection block 211 has a length, a gap is provided between the fixing plate 41 and the second mounting base 21. The fixing of the transmitting device is completed, and at this time, air can pass through the first heat dissipation holes 11 from the space above and at the side surface of the first heat dissipation holes 11 and enter the transmitting device to dissipate heat of the transmitting module in the transmitting device.
When the launching device needs to be disassembled, the bolts between the fixing holes 411 and the second mounting holes 212 are loosened, so that the second mounting base 21 can be separated from the fixing plate 41, at the moment, the fixing bolts 313 are loosened, the second mounting base 21 is separated from the threaded column 311, then the second mounting base 21 is turned over, the second connecting block 211 faces downwards, and the second mounting base 21 at the moment is fixed on the threaded column 311 again.
Then, the fixing bolt 313 is screwed to drive the threaded column 311 to rotate, so that the threaded column 311 moves to the lower side of the first mounting base 6 until the lower end surface of the second mounting base 21 is attached to the upper end surface of the first mounting base 6. At this time, the second mounting base 21 and the second mounting hole 212 can play a role in protecting the transmitting device, and the occupied space is small, so that the transmitting device can be transported together, and the transmitting device can still be protected in the transportation process.
Compared with the prior art, according to the LED-based visible light communication system transmitting device, when the installation environment is limited, air can still enter the transmitting device through the first radiating holes, and the radiating effect is not easy to reduce.
