Description

Technical Field

[0001] This utility model relates to the field of air conditioner companion technology, and in particular to a USB air conditioner companion structure. Background Technology

[0002] In some regions, due to constraints imposed by geographical and climatic conditions, energy structure, and power grid infrastructure construction, power grid stability has long been poor. This manifests as frequent power fluctuations, voltage instability, and low power supply reliability, especially at night when the power grid prioritizes the needs of critical sectors such as government agencies, severely restricting electricity supply for ordinary residents. To meet basic living needs, local residents generally rely on large diesel generators deployed in the area as supplementary power. However, this power supply model requires users to pre-purchase electricity based on household consumption quotas, creating a "quota allocation + self-generation" electricity ecosystem. Under this model, users place higher demands on the energy efficiency management, environmental adaptability, and operational stability of power equipment.

[0003] To protect the safe operation of electrical equipment in unstable power supply environments, small, portable USB automatic power reduction devices have emerged on the market. The core function of these devices is to monitor input voltage fluctuations in real time using built-in sensors and automatically adjust the output power based on the monitoring results. This effectively prevents damage to electrical equipment caused by abnormal voltage and alleviates the problems caused by unstable power supply to a certain extent.

[0004] However, existing small, portable USB automatic power reduction devices have key shortcomings when dealing with special environments in some regions. Some areas have high dust concentrations, and existing devices mostly use open-type heat dissipation structures or ordinary filter designs. Open-type heat dissipation structures allow direct communication between the device's interior and the external environment, making it easy for dust to penetrate the device without obstruction. Ordinary filters have limited effectiveness in filtering fine particles and are unable to effectively block high concentrations of dust. Once inside the device, dust adheres to critical components such as circuit boards and electronic components, affecting the device's heat dissipation performance, causing the device temperature to rise, accelerating the aging of electronic components, and ultimately leading to device malfunctions. This significantly reduces the device's operational stability and fails to meet the high stability requirements of users in some regions.

[0005] In summary, existing small, portable USB automatic power reduction devices are significantly inadequate in dealing with the special environments of some regions. It is necessary to develop a device that can effectively adapt to sandstorm environments in some areas and improve operational stability in order to meet the power needs of local users. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a USB air conditioner companion structure.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] This utility model embodiment provides a USB air conditioner companion structure, including: a first housing, a USB control board and a second housing. The first housing and the second housing are connected to form an installation cavity for installing the USB control board. The first housing is connected to a button, which is electrically connected to the USB control board for switching the air conditioner's operating mode. The side wall of the first housing is provided with a first slope, and the side wall of the second housing is provided with a second slope. The first slope and the second slope cooperate to form a sealed state.

[0009] In one specific embodiment, the button has cantilever arms on both sides, the first housing has a positioning post, the cantilever arms are movably connected to the positioning post, and the lower outer side of the button also has a dustproof groove extending outward, the dustproof groove and the first housing cooperate to form a semi-closed structure.

[0010] In one specific embodiment, the cross-section of the dustproof groove is V-shaped.

[0011] In one specific embodiment, the depth of the dustproof groove is 0.4-0.8 mm.

[0012] In one specific embodiment, the button is composed of a metal part and a transparent part, the cantilever and the dustproof groove are disposed in the transparent part, and the metal part is provided with a CD texture layer.

[0013] In one specific embodiment, the angle between the second slope and the horizontal plane is 30-60 degrees.

[0014] In one specific embodiment, the first ramp portion is provided with a first helical tooth, and the second ramp portion is provided with a second helical tooth corresponding to the first helical tooth.

[0015] In one specific embodiment, the first housing is provided with a limiting post, and the second housing is provided with a supporting rib corresponding to the limiting post.

[0016] In one specific embodiment, the second housing is further provided with a support column.

[0017] In one specific embodiment, the first housing is provided with a snap-fit ​​portion, and the second housing is provided with a snap-fit ​​groove corresponding to the snap-fit ​​portion.

[0018] The advantages of this USB air conditioner companion structure compared to existing technologies are as follows: By setting a button on the first housing and electrically connecting the button to the USB control board, users can easily operate the button to switch the air conditioner's operating mode. This design allows users to flexibly adjust the air conditioner to a suitable operating state according to actual needs, such as indoor temperature and personal comfort. In particular, it enables the air conditioner to enter a power-reducing operating mode, reducing energy consumption while meeting basic cooling or heating needs. In areas with unstable power supply or scarce power resources, this power-reducing operating mode has significant practical value, extending the air conditioner's usage time under limited power supply and ensuring users' basic living needs. Additionally, the side wall of the first housing is provided with... The first ramp portion and the second ramp portion on the side wall of the second housing cooperate to form a sealed state. This structural design provides excellent dust protection for the equipment. In environments with high dust concentrations, traditional equipment, due to poor sealing, easily allows dust to penetrate the equipment and adhere to critical parts such as circuit boards and electronic components, affecting the normal operation of the equipment. However, the ramp portion design effectively blocks the entry of particles, greatly reducing the accumulation of dust inside the housing, avoiding the corrosion and damage of dust to the internal components of the equipment, and extending the service life of the equipment. In addition, because this structure effectively prevents particles from entering the housing, it avoids problems such as poor heat dissipation and short circuits of electronic components caused by dust accumulation, thereby significantly improving the operational stability of the equipment.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.

[0039] See Figures 1 to 9As shown, this utility model discloses a specific embodiment of a USB air conditioner companion structure, including: a first housing 10, a USB control board 20, and a second housing 30. The first housing 10 and the second housing 30 are connected to form an installation cavity for installing the USB control board 20. The first housing 10 is connected to a button 40, which is electrically connected to the USB control board 20 for switching the air conditioner working mode. The side wall of the first housing 10 is provided with a first slope portion 11, and the side wall of the second housing 30 is provided with a second slope portion 31. The first slope portion 11 and the second slope portion 31 cooperate to form a sealed state.

[0040] Specifically, the USB control board 20 integrates a push-button switch, and the button 40 is adapted to the push-button switch. By operating the button 40, the air conditioner's operating mode can be switched. More specifically, the first housing 10 is pre-set with mounting holes (preferably, the mounting holes are stepped spiral holes, which have a better decorative effect). The button 40 is installed in the mounting holes, ensuring that the button 40 can move up and down flexibly. When the user needs to switch the air conditioner's operating mode, they only need to press the button 40 lightly with their hand. After receiving pressure, the button 40 will move downwards and trigger the push-button switch on the USB control board 20. After receiving the pressure signal, the push-button switch will transmit the signal to the microprocessor on the USB control board 20. The microprocessor analyzes and processes the signal according to a preset program, and then outputs corresponding control commands, which are sent to the air conditioner through the USB interface, thereby causing the air conditioner to enter the corresponding operating mode, such as a power reduction mode.

[0041] In other words, by setting a button 40 on the first housing 10 and electrically connecting the button 40 to the USB control board 20, users can easily operate the button 40 to switch the air conditioner's operating mode. This design allows users to flexibly adjust the air conditioner to a suitable operating state according to actual needs, such as indoor temperature and personal comfort. In particular, it enables the air conditioner to enter a power-reducing operating mode, reducing energy consumption while meeting basic cooling or heating needs. In areas with unstable power supply or scarce power resources, this power-reducing operating mode has significant practical value, extending the air conditioner's usage time under limited power supply and ensuring users' basic living needs. In addition, the first slope 11 on the side wall of the first housing 10 and the second slope 31 on the side wall of the second housing 30 cooperate to form a sealed state. This unique structural design provides excellent dust protection for the device. In environments with high dust concentrations, traditional devices, due to poor sealing, easily allow dust to penetrate the device and adhere to critical parts such as circuit boards and electronic components, affecting the normal operation of the device. However, the slope design of this structure effectively blocks the entry of particulate matter, greatly reducing the accumulation of dust inside the housing. Compared to existing devices using open heat dissipation structures or ordinary filters, this structure physically constructs a reliable defense, preventing sand and dust from corroding and damaging internal components, thus extending the device's lifespan. Furthermore, because this structure effectively prevents particulate matter from entering the casing, it avoids problems such as poor heat dissipation and short circuits in electronic components caused by sand and dust accumulation, significantly improving the device's operational stability. In complex electrical environments, stable device performance is crucial. Taking some regions mentioned in the background technology as an example, the local power grid has poor stability and frequent power fluctuations, with residents relying on diesel generators for power, placing extremely high demands on the stability of electrical equipment. This USB air conditioner companion structure, through its excellent dustproof design, ensures that core components such as the USB control board 20 can operate continuously and stably in harsh environments, reducing the probability of device failure, lowering maintenance costs and downtime, and providing users with a more reliable user experience. Whether for daily home use or commercial applications, stable device operation ensures the normal operation of the air conditioning system, meeting people's needs for a comfortable environment.

[0042] See Figures 2 to 6 As shown, in one embodiment, the button 40 is provided with cantilever 421 on both sides, the first housing 10 is provided with positioning post 12, the cantilever 421 is movably connected to the positioning post 12, and the lower outer side of the button 40 is also provided with a dustproof groove 422, which cooperates with the first housing 10 to form a semi-closed structure.

[0043] Specifically, the cantilever 421 is movably connected to the positioning post 12, allowing the button 40 to move up and down along the positioning post 12. When external sand or dust tries to enter the device through the gap between the button 40 and the first housing 10, the sand or dust will fall into the dustproof groove 422, making it difficult for the sand or dust to fall into the device.

[0044] In other words, the design of the cantilever 421 movably connected to the positioning column 12 allows the button 40 to move up and down, and this connection provides stable support and movement guidance for the button 40. The positioning column 12 can limit the movement trajectory of the button 40, preventing the button 40 from deviating or shaking during movement, ensuring the accuracy and consistency of the button 40's operation. Regardless of how the user presses the button 40, the button 40 can move smoothly along the predetermined direction, thereby accurately triggering the corresponding control function, improving the device's operational performance and user experience. In addition, when external sand and dust try to enter the device through the gap between the button 40 and the first housing 10, the dustproof groove 422 plays a crucial blocking role. The sand and dust will first fall into the dustproof groove 422. Since the dustproof groove 422 and the first housing 10 cooperate to form a semi-closed structure, the sand and dust that enters is unlikely to fall into the device's interior through the dustproof groove 422. This design effectively reduces the damage of sand and dust to the internal electronic components of the device and lowers the risk of equipment failure caused by sand and dust accumulation. For example, in areas with frequent sandstorms or industrial environments, the equipment can operate stably for extended periods, reducing the frequency of maintenance and cleaning, and lowering operating costs. Furthermore, the dustproof groove 422 effectively prevents sand and dust from entering the equipment, protecting electronic components such as the USB control board 20 from sand and dust corrosion, thereby extending the lifespan of these components. Operating in a clean environment ensures the heat dissipation of electronic components, preventing overheating due to sand and dust accumulation, and reducing the probability of component aging, short circuits, and other malfunctions. Simultaneously, the stable movement of the buttons 40 prevents damage to the internal structure of the equipment due to improper button operation, further improving the overall reliability and lifespan of the equipment.

[0045] See Figure 3 , Figure 5 and Figure 6 As shown, in one embodiment, the cross-section of the dustproof groove 422 is V-shaped.

[0046] Specifically, the cross-sectional shape of the dustproof groove 422 is V-shaped. When external sand and dust try to enter the equipment through the gap between the button 40 and the first housing 10, they fall into the V-shaped groove. The V-shaped slope and the inner surface of the first housing 10 cooperate to form a semi-closed structure, making it difficult for the sand and dust to fall further into the equipment.

[0047] In other words, the unique shape of the V-shaped dustproof groove 422 gives it excellent sand and dust interception capabilities. When external sand and dust enter the device through the gap between the button 40 and the first housing 10, it first falls into the V-shaped groove. Due to the large opening of the V-shape, it can effectively capture sand and dust entering from different angles, greatly increasing the difficulty for sand and dust to enter the device. Compared with traditional flat or simple groove dustproof structures, the V-shaped dustproof groove 422 can intercept more sand and dust, improving dustproof efficiency. In addition, the V-shaped slope and the inner surface of the first housing 10 cooperate to form a semi-closed structure. This structure can effectively prevent sand and dust falling into the dustproof groove 422 from further entering the device. The slope design causes sand and dust to slide down the slope under the action of gravity, rather than entering the device. At the same time, the semi-closed structure can also reduce the impact of airflow on sand and dust, preventing sand and dust from being blown into the device by airflow, further enhancing the dustproof effect.

[0048] In one embodiment, the depth of the dustproof groove 422 is 0.4-0.8 mm.

[0049] Specifically, the dustproof groove 422, with a depth between 0.4 and 0.8 mm, forms a sufficiently deep containment space. When external sand and dust enter through the gap between the button 40 and the first housing 10, most of the sand and dust will fall into the dustproof groove 422. Due to the depth of the groove, sand and dust are less likely to be stirred up again and enter the equipment under slight airflow or vibration. Compared to a shallower dustproof groove 422, this greatly improves the sand and dust interception efficiency and reduces the amount of sand and dust entering the equipment. In addition, the appropriate groove depth helps to form a tighter fit between the dustproof groove 422 and the first housing 10. After assembly, the edge of the dustproof groove 422 can better fit with the surface of the first housing 10, forming a relatively closed space that prevents sand and dust from penetrating into the equipment through gaps. This sealing can effectively protect the electronic components and mechanical structures inside the equipment from sand and dust corrosion, reducing the risk of failure caused by sand and dust.

[0050] See Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 9 As shown, in one embodiment, the button 40 is composed of a metal part 41 and a transparent part 42, the cantilever 421 and the dustproof groove 422 are disposed in the transparent part 42, and the metal part 41 is provided with a CD texture layer.

[0051] Specifically, the USB control board 20 integrates LED lights. The first ramp 11 and the second ramp 31 work together to effectively prevent external sand and dust from entering the housing, while also preventing the light emitted by the LED lights from escaping along the connection between the first housing 10 and the second housing 30, thus preventing light leakage. The light emitted by the LED lights acts on the transparent part 42 to form a ring light effect, which, combined with the CD texture layer, enhances the aesthetics of the device and the user experience.

[0052] More specifically, the metal part 41 is made of a metal material with good texture, strength, and corrosion resistance, such as stainless steel or aluminum alloy. The transparent part 42 is made of a highly transparent plastic material, such as polycarbonate (PC) or acrylic. The metal part 41 and the transparent part 42 can be firmly bonded together by means of adhesive bonding or hot-melt welding.

[0053] In other words, the design of the first ramp 11 and the second ramp 31 not only prevents dust but also effectively blocks the light emitted by the LED from escaping along the connection between the first housing 10 and the second housing 30. The angle and length of the ramps cause the light to reflect and refract during propagation, preventing it from leaking directly out from the connection and avoiding light interference with the user, thus improving the user's comfort. Furthermore, the light-leakage prevention design makes the device's appearance cleaner and more aesthetically pleasing, avoiding the clutter caused by light leakage and making the device more visually harmonious and unified, enhancing the product's market competitiveness. Additionally, the light emitted by the LED acts on the transparent part 42, forming a unique ring-shaped lighting effect. This lighting effect is not only decorative but also clearly displays the position of the button 40 in dark environments, facilitating user operation. The CD texture layer on the metal part 41 produces a dazzling light and shadow effect under light, complementing the ring-shaped light of the transparent part 42 and further enhancing the device's aesthetics. At the same time, the CD texture layer also increases the friction of the button 40, making it more comfortable and accurate for the user to operate, improving the user experience.

[0054] In one embodiment, the angle between the second ramp portion 31 and the horizontal plane is 30-60 degrees.

[0055] Specifically, the angle between the second ramp portion 31 and the horizontal plane is between 30 and 60 degrees. This allows for greater normal pressure at the joint surface when the first housing 10 and the second housing 30 are assembled, thereby increasing friction and improving structural stability. For example, when the angle is 45 degrees, under the same assembly force, the normal pressure at the joint surface is greater, effectively preventing the first housing 10 and the second housing 30 from loosening or separating during use, ensuring normal operation of the equipment. Furthermore, a suitable angle design increases the contact area of ​​the joint surface, allowing the first ramp portion 11 and the second ramp portion 31 to form a more effective seal. This helps prevent external impurities such as sand and moisture from entering the equipment, extending its service life. Additionally, the 30-60 degree angle between the second ramp portion 31 and the horizontal plane alters the propagation path of the light emitted by the LED light at the joint surface of the first housing 10 and the second housing 30. When light shines on the ramp portion, reflection and refraction occur, making it difficult for light to leak directly from the joint. For example, when the angle is 60 degrees, the light undergoes multiple reflections and refractions at the slope, and most of the light is reflected back into the equipment or changes its propagation direction, thus effectively reducing light leakage.

[0056] In one embodiment, the first ramp portion 11 is provided with a first helical tooth, and the second ramp portion 31 is provided with a second helical tooth corresponding to the first helical tooth.

[0057] Specifically, after the first and second helical teeth mesh, a complex tortuous path is formed between the first slope portion 11 and the second slope portion 31. When sand and dust attempt to enter the equipment, they need to move along these tortuous paths, greatly increasing the difficulty of sand and dust entry. In addition, the meshing of the helical teeth increases the contact area and sealing pressure between the first slope portion 11 and the second slope portion 31, forming a more effective seal. Compared with traditional planar contact seals, helical tooth meshing seals can better prevent the entry of fine sand and dust. Furthermore, the surfaces of the first and second helical teeth have a certain tilt angle. When light shines on the surface of the helical teeth, reflection and refraction occur, changing the direction of light propagation. This makes it difficult for light to leak directly from the joint between the first slope portion 11 and the second slope portion 31, effectively reducing light leakage.

[0058] See Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, in one embodiment, the first housing 10 is provided with a limiting post 13, and the second housing 30 is provided with a supporting rib 32 corresponding to the limiting post 13.

[0059] Specifically, the limiting post 13 limits the USB control board 20 from the top, and the support rib 32 supports the USB control board 20 from the bottom. The limiting post 13 and the support rib 32 work together to reduce the shaking of the USB control board 20 and make it work smoothly.

[0060] In other words, the limiting post 13 limits the USB control board 20 from the top, restricting its upward movement in the vertical direction; the support rib 32 supports the USB control board 20 from the bottom, preventing it from moving downward in the vertical direction. Together, they form a stable constraint in the vertical direction, effectively reducing the swaying of the USB control board 20 in that direction. For example, when the device is subjected to vibration or impact, the USB control board 20 will not collide with surrounding components due to excessive vertical displacement, ensuring its normal operation.

[0061] See Figure 8 As shown, in one embodiment, the second housing 30 is further provided with a support column 33.

[0062] Specifically, the support column 33 can support the USB control board 20 from different positions and angles, and cooperate with the limiting column 13 and the support rib 32 to form a more stable multi-directional limiting structure. In addition, the addition of the support column 33 can distribute the weight of the USB control board 20 and the external forces it receives more evenly to the second housing 30, avoiding damage to the limiting column 13 or the support rib 32 due to excessive local stress, and extending the service life of the entire limiting support system.

[0063] See Figure 4 and Figure 8 As shown, in one embodiment, the first housing 10 is provided with a latching part 14, and the second housing 30 is provided with a latching groove 34 corresponding to the latching part 14.

[0064] Specifically, the engagement of the snap-fit ​​part 14 and the slot 34 forms a reliable mechanical connection, securely linking the first housing 10 and the second housing 30 together. Compared to traditional screw connections, snap-fit ​​connections eliminate the need for additional screws or other parts, reducing the number of connection points and lowering the risk of connection failure due to loose or detached screws. When the device is subjected to external impact or vibration, the tight fit between the snap-fit ​​part 14 and the slot 34 effectively resists the external force, preventing the first housing 10 and the second housing 30 from separating. For example, in portable devices, when the device is accidentally dropped or impacted, the snap-fit ​​connection ensures the integrity of the housing and protects internal components from damage.

[0065] In one embodiment, the USB control board 20 also integrates a Bluetooth module for communicating with the indoor unit of the air conditioner.

[0066] Specifically, by integrating a Bluetooth module, the USB control board 20 does not require a wired connection with the indoor unit of the air conditioner, avoiding cable tangles and limitations, and making the installation and use of the device more flexible and convenient.

[0067] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
