By using a temperature detector to detect when the outdoor temperature reaches a low temperature condition, the size of the heat dissipation vent is controlled by a retractable door, thereby reducing the heat dissipation rate and achieving the technical effect of heat preservation for the main body of the wireless signal enhancer.

[0006] This application provides a wireless signal enhancement device for the Internet of Things (IoT), including a base, an L-shaped plate, a temperature detector, a radio frequency amplifier body, and a telescopic gate. The base has a rectangular structure, with the temperature detector fixed to its front surface and the L-shaped plate symmetrically fixed to its rear surface. The L-shaped plate has mounting holes for wall mounting. Auxiliary handles are symmetrically fixed to the bottom of the base, facilitating installation and transport, and also allowing it to be placed flat on a horizontal table. The radio frequency amplifier body is detachably connected to the top surface of the base, and multiple antennas are rotatably connected to the top of the radio frequency amplifier body. The telescopic gate is slidably connected to the side of the top surface of the base and is symmetrically arranged.

[0007] The base also has an inner cavity. Electric telescopic rods are symmetrically fixed to the sides of the base and embedded within it.

The top of the folding door is fixed to the upper surface of the operating opening and away from the inner cavity. The bottom of the folding door is fixed to the top of the top column. The top of the fixing plate is fixed to the upper surface of the operating opening and close to the inner cavity. The side surface of the folding door has multiple heat dissipation vents, and the side surface of the fixing plate has fixing holes corresponding to the heat dissipation vents.

The first ball and the second ball are fixed to the upper surface of the first support plate and are evenly distributed. The first ball and the second ball are hemispherical and their radii decrease sequentially. The first capsule and the second capsule are fixed to the lower surface of the second support plate. The capsules are hemispherical and made of natural rubber. The first capsule and the second capsule are 0.1 cm thick and are filled with carbon dioxide. The first ball and the second ball correspond to the first capsule and the second capsule in sequence. Thin iron strips are fixed to the bottom of the first capsule and the second capsule. The first ball and the second ball are separate signal sources. The top of the first ball and the second ball is provided with a loop iron plate, which is in an open circuit state when it is not in contact with the thin iron strip. When it comes into contact with the thin iron strip, a circuit is formed, and a signal is transmitted to the controller. After receiving the signal, the controller controls the magnetic force of the first electromagnet. When the first ball and the second ball emit signals at the same time, the controller takes the signal of the second ball as the reference.

[0029] To facilitate understanding of the present invention, a more complete description of this application will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the invention. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of the present invention.

[0030] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] Example 1: As Figures 1 to 4 As shown, this application discloses a wireless signal enhancement device for the Internet of Things (IoT), comprising a base 100, an L-shaped plate 101, a temperature detector 102, a radio frequency amplifier body 200, and a telescopic door 210. The base 100 has a rectangular structure. The temperature detector 102 is fixed to the front surface of the base 100, and the L-shaped plate 101 is symmetrically fixed to the rear surface. The L-shaped plate 101 has mounting holes for wall mounting. Auxiliary handles 103 are symmetrically fixed to the bottom of the base 100, facilitating the installation and transport of the base 100 and allowing it to be placed flat on a horizontal table. The radio frequency amplifier body 200 is detachably connected to the top surface of the base 100, and multiple antennas 201 are rotatably connected to the top of the radio frequency amplifier body 200. The telescopic door 210 is slidably connected to the side of the top surface of the base 100 and is symmetrically arranged.

[0033] The base 100 also has an inner cavity 104. An electric telescopic rod 211 is symmetrically fixed to the side of the base 100 and embedded inside the base 100. The output end of the electric telescopic rod 211 passes through the upper surface of the base 100. The output end of the electric telescopic rod 211 is fixedly connected to the bottom of the telescopic gate 210. A closing plate 212 is symmetrically fixed to the bottom of the telescopic gate 210. A rectangular heat dissipation vent 105, adapted to the closing plate 212, is opened on the side of the base 100, and the lower part of the rectangular heat dissipation vent 105 is designed with an arc shape. A retaining plate 110 is fixed near the opening of the inner cavity 104. A retaining plate 202 is fixed to the bottom of the radio frequency amplifier body 200, and the retaining plate 110 also has a retaining groove adapted to the retaining plate 202.

[0034] Specific implementation: The base 100 is fixed to the wall with screws or bolts. Then, the snap-fit ​​plate 202 of the radio amplifier body is snapped into the snap-fit ​​slot of the snap-fit ​​plate 110. Using the temperature detector 102 on the front surface of the base 100, when the outdoor temperature is between -10℃ and 36℃, the electric telescopic rod 211 is in its maximum extended state, and the rectangular heat dissipation vents are in their maximum open state, providing good heat dissipation for the radio amplifier body 200. When the outdoor temperature is between -10℃ and -40℃, the electric telescopic rod 211 controls the telescopic gate 210 to move downwards in a gradient manner according to the decreasing outdoor temperature. When the bottom of the telescopic gate 210 contacts the top of the base 100, it is in a fully closed state. Furthermore, the rectangular design at the bottom of the rectangular heat dissipation vent 105 allows for partial heat dissipation even when the telescopic gate 210 is fully closed. Through the above control of the telescopic gate 210, the heat dissipation rate of the radio amplifier body 200 can be reduced in low-temperature outdoor environments, thus achieving a heat preservation effect.

[0035] Beneficial effects: By detecting changes in outdoor temperature through temperature detector 102, the retractable gate 210 can control the size of the rectangular heat dissipation vent 105, thereby reducing the heat dissipation rate of the radio amplifier body 200 in low outdoor temperatures, thus playing a role in heat preservation and preventing the internal components of the radio amplifier body 200 from being affected by low temperatures and thus affecting their working performance.

[0036] Example 2: In extreme outdoor low-temperature environments, after prolonged use, the internal components of the radio booster body 200 may age. Aging components operate with reduced efficiency, requiring more electrical energy to complete the same task, thus converting into more heat energy and increasing heat generation. Because the extreme outdoor temperature causes the retractable gate 210 to reduce the size of the heat dissipation vent 221, heat may accumulate in the inner cavity 104, further affecting the performance of the radio booster body 200. Therefore, improvements are made to the retractable gate 210. This application proposes the following technical solution to address the above-mentioned technical problems:

[0037] like Figures 5 to 8 As shown, the closed plate 212 has an operating opening 203, and a cylindrical groove 106 is formed in the middle of the lower surface of the operating opening 203. A first electromagnet 223 is fixed at the bottom of the cylindrical groove 106, and a top post 224 is slidably connected inside the cylindrical groove 106. The top post 224 is made of hollow plastic material, and a magnet is provided at the bottom of the top post 224.

[0038] The closing plate 212 also includes a folding door 220, a fixing plate 222, and a sensing expansion mechanism; the top of the folding door 220 is fixed to the upper surface of the opening 203 and away from the inner cavity 104; the bottom of the folding door 220 is fixed to the top of the top column 224; the top of the fixing plate 222 is fixed to the upper surface of the opening 203 and close to the inner cavity 104.

[0039] The side surface of the folding door 220 has multiple heat dissipation vents 221, and the side surface of the fixing plate 222 has fixing holes 2221 corresponding to the heat dissipation vents 221. The heat dissipation vents 221 are connected to the inner cavity 104 through the fixing holes 2221, and the length of the fixing plate 222 is two-thirds of the unfolded length of the folding door 220.

[0040] The inductive expansion mechanism includes an L-shaped connecting plate 225, a first support plate 2251, a second support plate 2252, a first ball block 230, a second ball block 240, a first bladder 260, a second bladder 270, and a controller; one end of the L-shaped connecting plate 225 passes through the base 100 and is fixed to the first electromagnet 223; the other end of the L-shaped connecting plate 225 is fixed to the middle of the first support plate 2251, and the top of the L-shaped connecting plate 225 is fixed to the second support plate 2252;

[0041] The first support plate 2251 has a first ball block 230 and a second ball block 240 fixed on its upper surface, and they are equidistantly distributed; the first ball block 230 and the second ball block 240 are hemispherical in shape, and their radii decrease sequentially.

[0042] The lower surface of the second support plate 2252 is fixed with the first bladder 260 and the second bladder 270, which are hemispherical in shape and made of natural rubber; the thickness of the first bladder 260 and the second bladder 270 is 0.1 cm, and they are filled with carbon dioxide; the first spherical block 230 and the second spherical block 240 correspond to the first bladder 260 and the second bladder 270 respectively; thin iron strips 280 are fixed to the bottom of the first bladder 260 and the second bladder 270.

[0043] The first ball block 230 and the second ball block 240 are separate signal sources. The top of the first ball block 230 and the second ball block 240 is provided with a loop iron plate 250, which is in an open circuit state when it is not in contact with the thin iron bar 280. When it comes into contact with the thin iron bar 280, a circuit is formed, which transmits a signal to the controller. After receiving the signal, the controller controls the magnetic force of the first electromagnet 223. When the first ball block 230 and the second ball block 240 emit signals at the same time, the controller takes the signal of the second ball block 240 as the standard.

[0044] Determine the relevant physical quantities and formulas:

[0045] The capsule is a hemisphere, and its volume is calculated using the formula... (r is the radius), the initial expansion radius of the bladder is 3cm, the bladder thickness is 0.1cm, and the elastic modulus of natural rubber is E = 2~4MPa, taking E = 2MPa.

[0046] For the thermal expansion of gases, the formula is ΔV = V0βΔT (where β is the coefficient of expansion, ΔT is the temperature change, and V0 is the initial volume). The elastic resistance of natural rubber is determined by Huke's Law: F = kΔT. x Considering the structure and stress of the capsule, the relationship between elastic resistance and deformation is calculated using the elastic modulus E. (A is the area of ​​force application, ΔL is the change in length, and L is the initial length).

[0047] The relationship between the change in the surface area and the change in the radius of the cyst needs to be considered. The formula for the surface area of ​​the cyst is S = 2πr. 3 (Surface area of ​​a hemisphere). Calculate the initial volume and surface area:

[0048] Given the initial radius r0 = 3cm = 0.03m, then the initial volume is:

[0049] Initial surface area:

[0050] Consider the volume change caused by gas expansion:

[0051] The expansion coefficient of carbon dioxide is known. When the temperature increases by ΔT = 1℃, the gas volume changes

[0052]

[0053] Consider the expansion of natural rubber:

[0054] The coefficient of thermal expansion of natural rubber β rubber =21.6*10 -4 / K=21.6*10 -4 / ℃ (because 1K = 1℃).

[0055] Since the cyst thickness d = 0.1 cm = 0.001 m, the cyst can be considered a thin-walled structure. Its volume change ΔV rubber It can be approximately calculated by the change in surface area.

[0056] Surface area change: ΔS=S0β rubber ΔT = 0.0018π * 21.6 * 10 -4 *1≈1.225*10 -5 m 2 .

[0057] Corresponding volume change: ΔV rubber ≈ΔS*d=1.225*10 -5 *0.001=1.225*10 -8 m 3 .

[0058] Calculate the radius change caused by elastic resistance:

[0059] Let the change in radius be Δr, and the change in surface area be ΔS = 4πr₀Δr (for S = 2πr). 2 Differentiating, we get dS = 4πrdr.

[0060] The elastic modulus E = 2 MPa = 2 * 10 6 Pa, according to Here, A = S0 = 0.0018πm 2 , L=r0=0.03m, ΔL=Δr.

[0061] First, calculate the force F generated by the expansion of carbon dioxide and natural rubber, based on pressure. The pressure here is generated by carbon dioxide and natural rubber. Let's assume the pressure generated by the expansion of carbon dioxide is P. gas The pressure generated by natural rubber is P. ru bb er .

[0062] (P0 is atmospheric pressure), (V rubber V is the volume of natural rubber. rubber ≈S0*d=0.0018π*0.001≈5.655*10 -6 m 3 ).

[0063] F = (P gas +P rubber Substitute A achievable

[0064] After calculation:

[0065] (P0 is atmospheric pressure).

[0066]

[0067] ΔP total =P gas +P rubber ≈(0.003742+0.002166)P0=0.005908P0.

[0068] Substitution E = 2 * 10 6 Pa, r0=0.03m, P0=1.013*10 5 Pa (at normal pressure), can be obtained

[0069] Convert back to radius: (Radius derived from the volume of a hemisphere)

[0070] Temperature rises by ℃ New radius cm 1 <![CDATA[9*10 -4 ]]> 10 <![CDATA[9*10 -3 ]]> 20 <![CDATA[1.8*10 -2 ]]>

[0071] Working process: When the temperature inside the inner cavity 104 rises from 20℃ to 30℃, the first capsule 260 expands to 9*10 mm due to heat. - 3 cm (the first ball block 230 and the second ball block 240 both expand synchronously), the thin iron strip 280 on the first bladder 260 contacts the circuit iron piece 250 of the first ball block 230 (the thin iron strip 280 contacts the circuit iron piece 250, forming a circuit), giving a signal to the first electromagnet 223, the first electromagnet 223 generates an upward repulsive force on the magnet on the bottom surface of the top post 224 (this is the first supply of repulsive force), causing the top post 224 to move upward a certain distance, the top post 224 moves upward in the cylindrical groove 106 to lift the folding door 220, the folding door 220 folds, at this time a heat dissipation opening is formed between the folding door 220 and the action port 203 (this is the first stage of opening), and the heat dissipation port 221 on the folding door 220 is in a semi-connected state with the fixing hole 2221; when the temperature in the inner cavity 104 rises to 40℃, the second bladder 270 expands to 1.8*10 -2 cm, the thin iron strip 280 on the second bladder 270 contacts the circuit iron piece 250 of the second ball block 240, giving a signal to the first electromagnet 223. The first electromagnet 223 increases the repulsive force on the magnet on the bottom surface of the top post 224 again (this is the second supply of repulsive force). The top post 224 moves upward in the cylindrical groove 106 and lifts the folding door 220. At this time, a heat dissipation opening is formed between the folding door 220 and the action port 203 (this is the second level opening). The heat dissipation port 221 on the folding door 220 and the fixing hole 2221 are in the maximum connected state to achieve the heat dissipation effect.

[0072] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0073] When the extreme outdoor temperature causes the retractable gate 210 to reduce the size of the heat dissipation vent 221, the size of the function vent 203 can be adjusted according to the temperature change inside the inner cavity 104. Furthermore, the size of the connection between the heat dissipation vent 221 and the fixing hole 2221 increases as the temperature inside the inner cavity 104 rises. This not only prevents the accumulation of heat inside the inner cavity 104 but also ensures the radio enhancement effect of the radio amplifier body 200.

[0074] Example 3: When the folding door 220 is pushed upward by the top column 224, it may fold outward, causing the heat dissipation holes and fixing holes 2221 to malfunction, resulting in inaccurate heat dissipation based on the temperature in the inner cavity 104. To address the above technical problem, this application proposes the following technical solution:

[0075] like Figure 9 and Figure 10 As shown, an L-shaped limiting plate 300 is fixed to the side surface of the function port 203 and is symmetrically arranged. The L-shaped limiting plate 300 also has a second limiting groove 301. The side of the L-shaped limiting plate 300 near the inner cavity 104 is in contact with the fixing plate 222. A limiting plate 310 is fixed to the middle of the top surface of the function port 203. The side end of the folding door 220 is slidably connected in the second limiting groove 301. The width of the second limiting groove 301 is adapted to the width of the folding door 220 when folded. The limiting plate 310 limits the middle position of the folding door 220, and the L-shaped limiting plate 300 and the limiting plate 310 are arranged parallel to each other.

[0076] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0077] The folding door 220 is limited during the folding process to prevent it from folding outwards, thus ensuring accurate connection and heat dissipation between the heat dissipation vent 221 and the fixing hole 2221.

[0078] Example 4: The temperature in the inner cavity 104 may be slow to dissipate due to the aging of components. Slow heat dissipation will affect the user experience of the Internet of Things. In order to improve the heat dissipation speed, the L-shaped limiting plate 300 is improved. This application proposes the following technical solution to the above technical problem, specifically:

[0079] like Figures 11 to 14As shown, the top surface of the L-shaped limiting plate 300 has a through-hole 303; the surface of the L-shaped limiting plate 300 parallel to the fixing plate 222 has a rectangular vent 302, which passes through the L-shaped limiting plate 300 and the fixing plate 222 in sequence; the L-shaped limiting plate 300 also includes a vent shaft 320; the arc surface of the vent shaft 320 has a through-hole 321; the vent shaft 320 is rotatably connected in the through-hole 303, and the length of the vent shaft 320 is greater than the depth of the through-hole 303; a thin iron column 322 is fixed to the top surface of the vent shaft 320;

[0080] The upper surface of the working port 203 has a limiting circular groove 107, which is concentric with the elongated hole 303.
