Description

Technical Field

[0001] This invention relates to the field of broadcast television relay equipment technology, and more specifically, to a broadcast television relay equipment based on wireless transmission. Background Technology

[0002] Traditional televisions required an antenna to receive satellite signals. With the development of technology, modern televisions are connected to broadband networks to receive digital information. Modern televisions require conversion through a digital video converter to play their signals. As one of the most common television broadcasting devices, the digital video converter plays a positive role in people's daily lives and entertainment.

[0003] Existing technology involves embedding a wireless module inside a digital video converter box and then attaching the device to the back of the TV using a suction cup. However, due to the narrow space between the back of the wall-mounted TV and the wall, heat from the ventilation vents at the bottom of the back of the TV accumulates and moves upwards. When the suction cup is heated, a small amount of air inside expands, creating gaps that can easily cause the device to fall and be damaged. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a broadcast television relay device based on wireless transmission.

[0005] This invention provides a wireless transmission-based broadcast television relay device applied to the back of a television set. It includes a device body, sleeves, memory springs, a vacuum suction cup, and a heat sink. Multiple sleeves are fixed at the corners of the rear end face of the device body. The memory springs are disposed inside the sleeves, which are filled with heat-conducting oil. The vacuum suction cup is disposed at the open end of the sleeve. The heat sink is fixed in the middle of the rear end face of the device body. The heat sink is used to transfer heat from the television's heat dissipation vents to the heat-conducting oil, so that the memory springs can extend and drive the vacuum suction cup to move relative to the sleeves.

[0006] Optionally, a piston plate is slidably connected to the inner surface of the sleeve, and the two ends of the memory spring are fixedly connected to the inner bottom surface of the sleeve and the inner end surface of the piston plate, respectively. A connecting column is fixedly provided in the middle of the side of the piston plate away from the memory spring, and a vacuum suction cup is fixedly provided at the end of the connecting column away from the piston plate. The heat transfer oil is filled between the inner bottom surface of the sleeve and the inner end surface of the piston plate.

[0007] Optionally, the radiator is provided with a curved pipe inside, and the two ends of the curved pipe are symmetrically and fixedly connected to a first pipe. The two ends of the first pipe are fixedly connected to the inner side wall of the corresponding sleeve. Both the curved pipe and the first pipe are filled with heat-conducting oil.

[0008] Optionally, a fan is fixedly installed at the bottom of the heat sink, and the fan is electrically connected to an external power source.

[0009] Optionally, a protective mechanism is provided at the bottom of the device body, which is used for buffer protection when the device body is dropped.

[0010] Optionally, the protection mechanism includes a sleeve, a telescopic spring, a piston rod, a base plate, and a second pipe. Multiple sleeves are uniformly fixed on the bottom end of the equipment body. The piston rod is slidably connected to the inner surface of the sleeve. The two ends of the telescopic spring are respectively fixedly connected to the bottom end of the equipment body and the inner end face of the piston rod. The base plate is fixedly provided on the outer end face of the piston rod. Heat-conducting oil is filled between the bottom end of the equipment body and the inner end face of the piston rod. A second pipe is fixedly connected to the inner wall of the sleeve, and the other end of the second pipe is fixedly connected to the side wall of the corresponding first pipe.

[0011] Optionally, a cushioning pad is attached to the bottom end of the base plate.

[0012] Optionally, a fixing ring is fixedly provided on the outer side of the connecting column, and a pressing plate is fastened between the outer sides of the two fixing rings.

[0013] Optionally, an anti-slip pad is attached to the front end face of the device body.

[0014] The beneficial effects of the wireless transmission-based broadcast television relay equipment of this invention are:

[0015] 1. When installing the device, since the distance between the back of the TV and the wall is narrow, move the vacuum suction cup towards the sleeve. At this time, the memory spring is compressed inward. Then, hold the device and slowly place it into the gap between the back of the TV and the wall. When it is in the right position, squeeze the vacuum suction cup with the device to make the vacuum suction cup adhere to the back of the TV away from the heat dissipation vent. Then, slowly release the vacuum suction cup and the device. Under the push of the memory spring returning to its original deformation, the device moves in the opposite direction relative to the back of the TV until it is blocked and limited by the wall. At this time, the device is fixed by the vacuum suction cup.

[0016] 2. The equipment body is further secured by the elastic thrust of the memory spring;

[0017] 3. When the TV is in normal use, the internal heat is discharged through the heat dissipation vent at the bottom of the back of the TV. The discharged heat accumulates in the narrow space and moves upward. At this time, the heat sink fully absorbs the heat and then transfers the heat to the heat-conducting oil filled inside the sleeve. Since the memory spring is immersed in the heat-conducting oil, the memory spring is heated evenly and then elongates, driving the vacuum suction cup to move relative to the sleeve. Since the vacuum suction cup has been attached to the back of the TV, the memory spring generates enough thrust to make the vacuum suction cup firmly attached to the back of the TV, further fixing the device body.

[0018] 4. Because the heat transfer oil expands slightly when heated, it further improves the adhesion of the vacuum suction cup, solving the problem of the vacuum suction cup easily falling off when heated, and protecting the equipment body from being damaged by falling.

[0030] In the description of this specification, the references to terms such as "embodiment," "one embodiment," "some implementations," "exemplary," and "one implementation," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or implementation of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0031] The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0032] like Figure 1-8 As shown, this embodiment of the invention provides a wireless transmission-based broadcast television relay device applied to the back of a television set. It includes a device body 100, sleeves 200, a memory spring 201, a vacuum suction cup 204, and a heat sink 700. Multiple sleeves 200 are fixed at the corners of the rear end face of the device body 100. The memory spring 201 is disposed inside the sleeve 200, which is filled with heat-conducting oil. The vacuum suction cup 204 is disposed at the open end of the sleeve 200. The heat sink 700 is fixed in the middle of the rear end face of the device body 100. The heat sink 700 is used to transfer heat from the television's heat dissipation vents to the heat-conducting oil, so that the memory spring 201 can extend and drive the vacuum suction cup 204 to move relative to the sleeve 200.

[0033] In this embodiment, when installing the device body 100, because the distance between the back of the TV and the wall is narrow, the vacuum suction cup 204 is moved closer to the sleeve 200. At this time, the memory spring 201 is compressed inward. Then, the device body 100 is slowly placed into the gap between the back of the TV and the wall. When in the appropriate position, the device body 100 presses against the vacuum suction cup 204, causing the vacuum suction cup 204 to adhere to the back of the TV away from the heat dissipation vent. Then, the vacuum suction cup 204 and the device body 100 are slowly released. Under the push of the memory spring 201 returning to its original deformation, the device body 100 moves in the opposite direction relative to the back of the TV until it is blocked and limited by the wall. At this time, the vacuum suction cup 204 fixes the device body 100, and the elastic pushing force of the memory spring 201 further secures it. The device body 100 is fixed. When the TV is in normal use, the internal heat is discharged through the heat dissipation vent at the bottom of the back of the TV. The discharged heat accumulates in the narrow space and moves upward. At this time, the heat sink 700 fully absorbs the heat and then transfers the heat to the heat-conducting oil filled inside the sleeve 200. Since the memory spring 201 is immersed in the heat-conducting oil, the memory spring 201 is heated evenly and then elongates, driving the vacuum suction cup 204 to move relative to the sleeve 200. Since the vacuum suction cup 204 has been adsorbed on the back of the TV, the memory spring 201 generates enough thrust to make the vacuum suction cup 204 firmly adsorbed on the back of the TV, further fixing the device body 100. Since the heat-conducting oil expands slightly when heated, it also further improves the adsorption of the vacuum suction cup 204.

[0034] The device body 100 is limited by the wall and the deformation thrust of the memory spring 201 drives the vacuum suction cup 204 to firmly adhere to the back of the TV. The heat emitted by the TV during operation heats the heat transfer oil, which drives the memory spring 201 to extend and squeeze, further improving the adhesion of the vacuum suction cup 204. This solves the problem that the vacuum suction cup 204 is easy to fall off when heated, and protects the device body 100 from falling and being damaged.

[0035] like Figure 1 and Figure 8 As shown, optionally, a piston plate 202 is coaxially slidably connected to the inner surface of the sleeve 200. The two ends of the memory spring 201 are fixedly connected to the inner bottom surface of the sleeve 200 and the inner end surface of the piston plate 202, respectively. A connecting post 203 is fixedly provided in the middle of the side of the piston plate 202 away from the memory spring 201. A vacuum suction cup 204 is fixedly provided at the end of the connecting post 203 away from the piston plate 202. Heat transfer oil is filled between the inner bottom surface of the sleeve 200 and the inner end surface of the piston plate 202.

[0036] In this embodiment, when the television is in normal use, the internal heat is discharged through the heat dissipation vent at the bottom of the back of the television. The discharged heat accumulates in the narrow space and moves upward. At this time, the heat sink 700 fully absorbs the heat and then transfers it to the heat-conducting oil between the inner bottom surface of the sleeve 200 and the inner end face of the piston plate 202. The memory spring 201 is immersed in the heat-conducting oil, so the memory spring 201 is uniformly heated by the heat-conducting oil. When the temperature is reached, the memory spring 201 will extend. Since the device body 100 is limited by the wall at this time, the extension of the memory spring 201 will push the piston plate 202 to move away from the device body 100 inside the sleeve 200. Then, through the connecting column 203, the vacuum suction cup 204 is driven to firmly squeeze and adhere to the back of the television, preventing it from falling off due to heat and protecting the device body 100. Here, the memory spring 201 is made of nickel-titanium alloy.

[0037] like Figure 2 and Figure 4 As shown, optionally, a curved pipe 500 is fixedly provided inside the radiator 700, and a first pipe 400 is symmetrically fixedly connected to both ends of the curved pipe 500. Both ends of the first pipe 400 are fixedly connected to the inner side wall of the corresponding sleeve 200. Both the curved pipe 500 and the first pipe 400 are filled with heat-conducting oil.

[0038] In this embodiment, when the television is in normal use, the internal heat is discharged through the heat dissipation vent at the bottom of the back of the television. The discharged heat accumulates in the narrow space and moves upward. At this time, the radiator 700 can absorb the heat discharged from the heat dissipation vent at the back of the television and then transfer the heat to the heat-conducting oil filled inside the sleeve 200. Here, the curved pipe 500 has an S-shaped structure. Through the structural design of the curved pipe 500, the absorbed heat can be fully transferred to the heat-conducting oil inside the curved pipe 500. Then, the heat-conducting oil inside the curved pipe 500 transfers the heat to the heat-conducting oil in the first pipe 400. Then, the heat-conducting oil in the first pipe 400 transfers the heat to the heat-conducting oil between the bottom surface of the sleeve 200 and the inner end face of the piston plate 202, thereby uniformly heating the memory spring 201 inside the sleeve 200.

[0039] like Figure 2 As shown, optionally, a fan 701 is fixedly mounted on the bottom of the heat sink 700, and the fan 701 is electrically connected to an external power supply.

[0040] In this embodiment, heat begins to accumulate at the bottom heat dissipation vent on the back of the TV. Then, the fan 701 can absorb the heat accumulated between the back of the TV and the wall and blow it into the radiator 700, so that the radiator 700 can fully absorb the heat. At the same time, the fan 701 drives the airflow between the back of the TV and the wall to avoid the temperature from getting too high due to heat accumulation, thus avoiding affecting the wireless signal.

[0041] like Figure 2 As shown, optionally, a protective mechanism is provided at the bottom of the device body 100, which is used for buffer protection when the device body 100 falls.

[0042] In this embodiment, if an accident occurs and the device body 100 falls through the gap between the back of the television and the wall, the protection mechanism will be triggered to protect the device body 100 from being damaged.

[0043] like Figure 2 and Figure 7 As shown, optionally, the protection mechanism includes a sleeve 300, a telescopic spring 301, a piston column 302, a base plate 303, and a second pipe 600. Multiple sleeves 300 are uniformly fixed on the bottom end of the equipment body 100. The piston column 302 is slidably connected to the inner surface of the sleeve 300. The two ends of the telescopic spring 301 are fixedly connected to the bottom end of the equipment body 100 and the inner end face of the piston column 302, respectively. The base plate 303 is fixedly provided on the outer end face of the piston column 302. Heat transfer oil is filled between the bottom end of the equipment body 100 and the inner end face of the piston column 302. The second pipe 600 is fixedly connected to the inner wall of the sleeve 300. The other end of the second pipe 600 is fixedly connected to the side wall of the corresponding first pipe 400.

[0044] In this embodiment, during the initial fixation of the device body 100, the vacuum suction cup 204 needs to be moved closer to the sleeve 200. At this time, the internal piston plate 202 moves inward synchronously and squeezes the heat transfer oil. The heat transfer oil enters the first pipe 400 and eventually enters the second pipe 600, then enters the sleeve 300 and squeezes the piston column 302, causing the piston column 302 to move vertically downward. The movement of the piston column 302 allows the vacuum suction cup 204 to move smoothly inward. When the device body 100 accidentally falls, the vacuum suction cup 204 can be moved inward smoothly. Since the equipment body 100 is close to the wall, it will fall vertically along the wall. At this time, the base plate 303 will contact the ground. Then, the equipment body 100 will move downward relative to the base plate 303. At this time, the telescopic spring 301 will be compressed and will provide buffer protection. At the same time, since the space for heat transfer oil in the sleeve 300 becomes smaller, the heat transfer oil will be compressed and transported upward. At this time, the heat transfer oil will act as a damping agent, thus functioning similarly to a damping spring, preventing the equipment body 100 from bouncing repeatedly on the ground, reducing the probability of damage to the equipment body 100, and the structure on the back can also provide protection.

[0045] like Figure 7 As shown, optionally, a buffer pad is attached to the bottom end of the base plate 303.

[0046] In this embodiment, when the device body 100 is accidentally dropped, it will fall vertically along the wall because it is close to the wall. At this time, the base plate 303 will contact the ground. The buffer pad attached to the bottom of the base plate 303 will contact the ground to reduce the vibration generated when the base plate 303 contacts the ground, thereby reducing the vibration amplitude of the device body 100 and providing further protection.

[0047] like Figure 1 and Figure 2 As shown, optionally, a fixing ring 801 is fixedly provided on the outer side of the connecting column 203, and a pressing plate 800 is fastened between the outer sides of the two fixing rings 801.

[0048] In this embodiment, during the initial installation of the device body 100, the device body 100 is held by both hands on both sides, and the pressing plates 800 on both sides are pressed to move the vacuum suction cups 204 on both sides toward the sleeve 200, so as to place the device body 100 in the gap between the back of the TV and the wall. Then the vacuum suction cups 204 are pressed and adsorbed onto the back of the TV. Next, the pressing plates 800 are released, and then the device body 100 is slowly released, so that the device body 100 is pushed by the memory spring 201 to adhere to the wall, thus completing the initial adsorption and fixation.

[0049] like Figure 3 As shown, optionally, an anti-slip pad 900 is attached to the front end face of the device body 100.

[0050] In this embodiment, when installing the device body 100, the vacuum suction cup 204 is moved close to the sleeve 200. At this time, the memory spring 201 is compressed inward. Then, the device body 100 is held and slowly placed into the gap in the wall. The vacuum suction cup 204 is squeezed at a suitable position, so that the vacuum suction cup 204 is attached to the back of the TV. Then, the vacuum suction cup 204 and the device body 100 are slowly released. Under the push of the memory spring 201, the device body 100 moves in the opposite direction until it is blocked and limited by the wall. At this time, the anti-slip pad 900 is pressed and adhered to the wall surface. The anti-slip pad 900 improves the friction performance between the device body 100 and the wall surface, thereby improving stability. At this time, the device body 100 is fixed by the vacuum suction cup 204, and the anti-slip pad 900 improves the stability of the installation of the device body 100.

[0051] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
