Description

Technical Field

[0001] This utility model relates to the field of signal receiving equipment technology, specifically a portable network signal receiving device. Background Technology

[0002] A network consists of numerous nodes and links connecting these nodes, representing many objects and their interrelationships. Networks, through software tools such as text reading, image viewing, audio and video playback, downloading and transferring, games, and chat, bring people an extremely rich life and enjoyable experience in terms of text, images, sound, and video. A network signal receiving device is a device used to effectively receive network signals. Network signal receiving devices play an important role in sensing systems; their function is to convert the received network signals into electrical signals that the system can recognize.

[0003] Existing network signal receiving devices can be divided into two types: fixed and portable. Portable network signal receiving devices generally have a fixed battery, which allows the network signal receiving device to be used without external power supply. However, after the battery is depleted, it needs to be charged by an external power source before it can be used again, which is inconvenient. Utility Model Content

A circuit board is fixedly connected to the connecting posts. The housing is also provided with a heat dissipation mechanism for reducing the temperature of the circuit board during operation. The housing is also provided with a power supply mechanism for providing electrical energy, which includes a removable and replaceable lithium battery.

[0005] Preferably, the antenna includes a connecting substrate, which is fixedly connected to the outer shell. Two fixing blocks are symmetrically fixedly connected to the connecting substrate, and the antenna body is rotatably connected to the two fixing blocks.

[0006] Preferably, the heat dissipation mechanism includes an air inlet and an air outlet, with an air inlet and an air outlet respectively opened at both ends of the outer casing, and an exhaust fan is provided at the air outlet to discharge the air inside the outer casing to the outside.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, the lithium battery is locked to the outer casing by a locking plate through a power supply mechanism.

[0015] In this embodiment, the antenna 3 includes a connecting substrate 301, which is fixedly connected to the outer shell 2. Two fixing blocks 302 are symmetrically fixedly connected to the connecting substrate 301, and the antenna body 303 is rotatably connected to the two fixing blocks 302.

[0016] In this embodiment, the antenna body 303 can be flipped into a vertical state when in use, which can enhance the signal reception effect. When it needs to be carried, the antenna body 303 can be flipped into a horizontal state, reducing the space occupied and making it convenient to store when carrying.

[0017] In this embodiment, the heat dissipation mechanism 5 includes an air inlet 202 and an air outlet 203. The two ends of the outer casing 2 are respectively provided with an air inlet 202 and an air outlet 203. An exhaust fan 501 is provided at the air outlet 203 to discharge the air inside the outer casing 2 to the outside.

[0018] In this embodiment, the power supply mechanism 6 includes a fixed bracket 602, which is fixedly connected to the inner wall of the outer shell 2. The rear side of the outer shell 2 has a mounting hole 204, in which a power supply module 603 is fixedly connected. The front side of the outer shell 2 has a placement hole 205, in which a lithium battery 601 is slidably inserted. The lithium battery 601 is also slidably connected to the fixed bracket 602. One end of the lithium battery 601 abuts against the power supply module 603, and the other end of the lithium battery 601 is fixedly connected to a sealing plate 604. Two positioning protrusions 605 are symmetrically arranged on the sealing plate 604. Two locking pieces 606 are symmetrically rotatably connected on both sides of the placement hole 205. The locking pieces 606 have locking grooves 607, and the positioning protrusions 605 are slidably connected in the locking grooves 607.

[0019] In this embodiment, the power supply module 603 is provided with a charging port, which can charge the lithium battery 601 that is attached to the power supply module 603, and at the same time supply power to the circuit board 4 and the fan, so that the device can be used when plugged in.

[0020] In this embodiment, the antenna 3 is electrically connected to the circuit board 4, the circuit board 4 is electrically connected to the power supply module 603, the exhaust fan 501 is electrically connected to the power supply module 603, the power supply module 603 is electrically connected to the lithium battery 601, and the top surface of the housing 2 is provided with a main switch 7 and a fan switch 8.

Then, flip the two antenna bodies 303 to a vertical position, press the power switch 7 to power the circuit board 4 via the power supply module 603, and the device will start working. When the device temperature is high, press the fan switch 8 to start the exhaust fan 501, which will expel the high-temperature air from the outer casing 2. At the same time, external air enters the outer casing 2 through the air inlet 202 to absorb the heat from the circuit board 4 during operation, thereby reducing the device temperature and ensuring network stability. After the lithium battery 601 has been supplying power for a period of time, the stored energy will be depleted. At this time, a new fully charged lithium battery 601 can be replaced. First, flip the two locking pieces 606 upwards to separate the locking groove 607 from the positioning protrusion 605, unlocking the depleted lithium battery 601. Then, pull the depleted lithium battery 601 out of the outer casing 2, slide the new fully charged lithium battery 601 into the casing, and flip the locking pieces 606 again to make the locking groove 607 engage with the positioning protrusion 605, locking the new lithium battery 601. The device can then be used again.
