Description

Technical Field

[0001] This utility model relates to the field of mobile phone holder technology, specifically to a mobile phone holder with wireless charging and heat dissipation functions. Background Technology

[0002] In existing technology, mobile phone stands have evolved from simple fixation devices to multifunctional auxiliary devices. With the increasing frequency of mobile device use, especially in high-energy-consuming scenarios such as gaming, video playback, and navigation, users face two main problems: severe device overheating and rapid battery drain. To address these issues, mobile phone stands integrating wireless charging and heat dissipation have emerged on the market. Patent CN202221227248.8 describes an intelligent heat dissipation mobile phone stand. Its main structure consists of an octagonal cross-section base, four clamping arms, clamping arm retraction / opening buttons, a ball joint interface, and an internal heat dissipation device. The heat dissipation device includes a boost circuit module, a battery protection module, an intelligent heat dissipation module, and a cooling fan. The intelligent heat dissipation module consists of two sets of thermistors, two fixed resistors, and a transistor, automatically controlling the fan's start / stop and speed adjustment by detecting the difference between the phone's surface temperature and the ambient temperature. The inner surface of the stand has a semiconductor heat dissipation coating and a honeycomb structure, and the clamping arms have heat dissipation holes, with optional solar panel power supply. The technical problem to be solved is that existing heat-dissipating phone holders do not have intelligent heat dissipation adjustment capabilities. Specifically, existing heat-dissipating phone holders mainly rely on fans for heat dissipation, but the fan speed is a fixed value and cannot adjust the cooling capacity according to the actual heat generation of the phone, which greatly limits the heat dissipation function. The technical effects achieved are: (1) The heat dissipation capacity is improved through structural design (semiconductor heat dissipation coating, honeycomb structure and intelligent control fan); the thermistor detects the temperature difference in real time and intelligently controls the heat dissipation fan. When the temperature difference is about 10°C, the fan starts and reaches the maximum speed when the temperature difference is about 20°C, avoiding the safety hazards caused by the phone overheating after long-term use; (2) The solar epoxy plate on the clamping arm improves the battery life; the bracket interface is set with multiple sets of different internal threads to facilitate connection with different bracket arms and facilitate application scenario switching; the USB interface can cope with the sudden situation of the phone running out of power, enhancing the practicality and adaptability of the product. However, the document does not describe the exact fan structure. Its internal surface heat dissipation structure is a columnar honeycomb structure, which is very complex. Moreover, the key technical problem it solves is that existing heat-dissipating phone holders do not have intelligent heat dissipation adjustment capabilities.

[0003] Patent CN202420498183.3 discloses a multifunctional mobile phone holder, mainly composed of two parts: a clamping part (10) and a supporting part (20). The clamping part (10) includes a heat dissipation component (30), a wireless charging coil (40), and a first circuit board electrically connecting the heat dissipation component (30) and the wireless charging coil (40). The heat dissipation component (30) includes a heat sink (31), a cooling plate (32), and a fan (33). In terms of structural design, the wireless charging coil (40) and the cooling plate (32) are both set on the first surface of the heat sink (31) close to the mobile phone, while the fan (33) and the first circuit board are set on the second surface of the heat sink (31) away from the mobile phone, and the hot end of the fan (33) and the cooling plate (32) are in contact, forming an efficient heat dissipation path. The second surface of the heat sink (31) is also provided with heat dissipation fins (311) to increase the heat dissipation area.

[0004] This patent primarily addresses the technical problem of existing mobile phone holders having limited functionality. However, it doesn't adequately address the actual needs of mobile phone use (such as heat dissipation and charging). The patent's cooling plate and fan are mounted before and after the heat sink, while the wireless charging coil is mounted above the cooling plate. Its main drawbacks are: 1. It has many components, requiring a heat sink, front cover, panel, cooling plate, and fan. 2. The wireless charging coil is above the cooling plate, resulting in low heat dissipation efficiency. 3. This design lacks an air vent that connects to the external environment, leading to very low heat dissipation efficiency. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a simple, efficient heat dissipation mobile phone holder with wireless charging and heat dissipation functions.

[0006] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0007] A mobile phone holder with wireless charging and heat dissipation functions includes a back cover, a front cover covering the back cover, and a charging component located in front of the front cover. It also includes a fan and a cooling plate. A fan is installed on the upper back of the front cover, and a first heat dissipation channel is formed on the back of the front cover on both sides of the fan. The first heat dissipation channel is connected to the external environment. The cooling plate is attached to the front of the front cover and is located between the charging component and the front cover. The power supply terminals of the fan and the cooling plate are both connected to the PCB circuit board inside the mobile phone holder.

[0008] Furthermore, the front cover is made of a metal material that facilitates heat dissipation, further aiding in heat dissipation. In this design, the fan blows directly onto the back of the front cover, achieving the effect of cooling the entire front cover. The phone holder uses heat pump technology internally, with a cooling plate positioned between the front cover and the charging component. The cooling plate has a cold end and a hot end; the cold end faces the phone and is responsible for absorbing the heat generated by the charging component; the hot end faces the fan and is used to release the absorbed heat. The fan not only directly cools the back of the front cover but also provides heat dissipation for the hot end of the cooling plate, forming a complete heat conduction and exhaust circulation system. In this design, the cooling plate is located between the charging component and the front cover, with the fan behind the front cover, achieving a high level of heat dissipation.

[0009] The entire heat dissipation and charging system is controlled by an internal PCB circuit board, which provides a stable power supply to the fan and cooling chip, ensuring that the phone maintains an ideal temperature during wireless charging, effectively preventing the phone from overheating, extending its lifespan, and improving charging efficiency.

[0010] Furthermore, a first recess is provided on the front of the front cover, the fan is located behind the first recess, and a cooling fin is installed inside the first recess.

[0011] The primary purpose of this first recessed design is to provide a compact and efficient heat dissipation space while also providing an area that facilitates installation.

[0012] The mobile phone holder also includes a mounting plate, which is embedded in a first recess. An O-ring is provided on the outer peripheral surface of the mounting plate that contacts the first recess. A through hole for placing a cooling chip is opened in the middle of the mounting plate, and the charging component is placed inside the mounting plate.

[0013] The primary purpose of the mounting plate is to act as a bridge connecting the charging components and the cooling system, providing an integrated mounting platform that neatly organizes key functional components such as the charging components and cooling pads. The achieved technical benefits include modular assembly and disassembly, facilitating production assembly and subsequent maintenance; a rationally designed through-hole layout ensures an efficient heat transfer path from the charging components to the cooling pads, reducing heat loss; furthermore, the mounting plate's fixing structure maintains precise relative positions between components, eliminating displacement caused by vibration or external forces, and enhancing the stability and reliability of the entire system during use. The mounting plate also supports and protects the charging components, preventing direct exposure to the external environment and extending the lifespan of the charging system. Simultaneously, it optimizes internal space utilization, making the entire phone holder structure more compact and lightweight.

[0014] The main purpose of this O-ring design is to form a reliable sealing barrier at the interface where the mounting plate contacts the first recess. The technical effect is to effectively prevent external dust, moisture, and foreign objects from entering the internal circuit system, protecting internal precision components from environmental pollution. At the same time, as an elastic element, the O-ring can absorb vibration and impact during use, reducing wear caused by direct contact between hard materials. In addition, the O-ring can also compensate for installation deviations and manufacturing tolerances, ensuring the stable positioning of the mounting plate in the recess. Even when the equipment is subjected to external forces or temperature changes, it can maintain a tight fit between components, extend the service life of the equipment, and improve overall reliability.

[0015] Furthermore, a second recess is provided at the middle position inside the first recess, and the cooling chip is embedded in the second recess and the through hole of the mounting plate.

[0016] Furthermore, the charging assembly includes a magnetic shielding sheet to prevent reverse wireless transmission, a wireless charging coil, and a cover. The magnetic shielding sheet covers the cooling plate, and the wireless charging coil is surrounded on the magnetic shielding sheet. The cover covers the magnetic shielding sheet and the wireless charging coil. The magnetic shielding sheet, the wireless charging coil, and the cover are all placed inside the mounting plate.

[0017] Furthermore, the mounting plate has a dividing ring inside, dividing the inside of the mounting plate into a first mounting area and a second mounting area. The first mounting area has a ring-shaped iron plate installed, and a magnetic inner ring and a magnetic outer ring with the same center are installed in front of the ring-shaped iron plate. The second mounting area has a magnetic shielding sheet and a wireless charging coil installed inside. The cover covers the mounting plate.

[0018] The annular iron plate in the first installation area, together with the magnetic inner ring and the magnetic outer ring, forms a powerful magnetic fixing system that can firmly attract and fix compatible mobile phones, ensuring that the phone will not fall off due to external force or vibration during charging. This makes the phone fit tightly, resulting in better charging performance and greatly improving the safety and stability of use.

[0019] The magnetic shielding sheet in the second mounting area plays a crucial role in electromagnetic shielding, effectively preventing the electromagnetic field generated by the wireless charging coil from leaking backward and concentrating the electromagnetic field for forward transmission. This improves charging efficiency and reduces potential electromagnetic interference to internal electronic components. The wireless charging coil achieves optimal energy transfer efficiency through precise coaxial winding and a perfect match with the magnetic inner and outer rings.

[0020] Furthermore, the upper end of the rear shell is provided with a cavity for accommodating the fan, and the back of the cavity is provided with a petal-shaped vent for the fan to circulate air, which is connected to the external environment.

[0021] Furthermore, the lower end of the rear shell is provided with a strip-shaped ventilation opening for the flow of fan air, and the top of the strip-shaped ventilation opening is connected to the receiving cavity.

[0022] Furthermore, the left and right sides of the cavity are provided with second heat dissipation channels, which are connected to the external environment. The rear shell and the front cover are flush-fitted together, and the first heat dissipation channel is aligned with the second heat dissipation channel.

[0023] Furthermore, a PCB circuit board is mounted on the lower back of the front cover, and the PCB circuit board also has a switch, which protrudes from the back cover. The main purpose of the switch is to prevent the phone holder from continuously charging the phone if the user does not remove the phone during charging, which could lead to overcharging of the battery and affect battery life and safety. When the phone is fully charged or the user does not need the charging function temporarily, the charging function can be turned off, but the holder's fixation function can still be used to reduce unnecessary energy consumption. This control mechanism also reduces the extra heat generated by continuous charging, reduces the burden on the heat dissipation system, and further improves the energy efficiency and lifespan of the entire device.

[0024] The front cover has a clearance hole through which the wires of the cooling chip pass to connect to the PCB circuit board; the wires of the wireless charging coil also pass through the clearance hole to connect to the PCB circuit board; a Type-C interface for powering the PCB circuit board is located at the bottom of the front cover, and an external power source passes through the back cover to power the PCB circuit board.

[0025] This invention has the following advantages over the prior art:

[0026] 1. Simplified Structure and Efficient Heat Dissipation: This design integrates the charging component, cooling plate, front cover, and fan into a unified thermal management system. The cooling plate is located between the charging component and the front cover, fully utilizing the heat pump principle. Compared to existing technologies, this patent eliminates the need for an additional heat sink as an intermediate medium, directly utilizing the metal front cover for heat conduction and dissipation. This simplifies the structure, improves its compactness, and enhances heat dissipation efficiency.

[0027] 2. The cold end of the cooling chip faces the phone to absorb heat, while the hot end faces the fan to release heat, forming a scientific heat conduction path, which is more reasonable than the heat dissipation component layout in existing technologies.

[0028] 3. This design has multiple heat dissipation channels that communicate with the external environment: the first heat dissipation channel on the back of the front cover, the petal-shaped vent at the top of the rear shell, the strip-shaped vent at the bottom, and the second heat dissipation channel. This multi-channel design forms a more efficient air circulation path.

[0029] 4. The modular design of the components is achieved through the first recess, mounting plate, O-ring and other structures, which facilitates assembly and maintenance.

[0030] 5. It integrates magnetic fixation, wireless charging, and efficient heat dissipation, solving the problem of mutual interference between functions in existing technologies.

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 11 The mobile phone holder shown includes a back cover 1, a front cover 2 covering the back cover 1, and a charging component 3 located in front of the front cover 2. It also includes a fan 4-1 and a cooling plate 5-1. The fan 4-1 is installed on the upper back of the front cover 2. A first heat dissipation channel 21 is formed on the back of the front cover 2 on both sides of the fan 4-1. The first heat dissipation channel 21 is connected to the external environment. The cooling plate 5-1 is attached to the front of the front cover 2 and is located between the charging component 3 and the front cover 2. The power supply terminals of the fan 4-1 and the cooling plate 5-1 are both connected to the PCB circuit board 10 inside the mobile phone holder.

[0052] In this embodiment, the front cover 2 is made of a metal material that facilitates heat dissipation, further aiding in heat dissipation. In this design, the fan 4-1 directly blows heat onto the back of the front cover 2, achieving the effect of dissipating heat for the entire front cover 2. The phone holder utilizes heat pump technology, with a cooling plate 5-1 positioned between the front cover 2 and the charging component 3. The cooling plate 5-1 has a cold end and a hot end; the cold end faces the phone and absorbs the heat generated by the charging component 3; the hot end faces the fan 4-1 and releases the absorbed heat. The fan 4-1 not only directly cools the front cover 2 but also provides heat dissipation for the hot end of the cooling plate 5-1, forming a complete heat conduction and exhaust circulation system. In this design, the cooling plate 5-1 is located between the charging component 3 and the front cover 2, with the fan 4-1 behind the front cover 2, achieving a high level of heat dissipation.

[0053] like Figure 3 As shown, the entire heat dissipation and charging system is controlled by the internal PCB circuit board 10, which provides a stable power supply to the fan 4-1 and the cooling chip 5-1, ensuring that the mobile phone maintains an ideal temperature during wireless charging, effectively preventing the mobile phone from overheating, extending its service life and improving charging efficiency.

[0054] In this embodiment, as Figure 2 , Figure 3 , Figure 4 As shown, a first recess 22 is provided on the front of the front cover 2, the fan 4-1 is located behind the first recess 22, and a cooling chip 5-1 is installed inside the first recess 22;

[0055] The primary purpose of the design of the first recess 22 is to provide a compact and efficient heat dissipation space structure, while also providing an area that is easy to install.

[0056] like Figure 2 , Figure 5 , Figure 12 As shown, the mobile phone holder also includes a mounting plate 7-1, which is embedded in the first recess 22. An O-ring 6-1 is provided on the outer peripheral surface of the mounting plate 7-1 that contacts the first recess 22. A through hole 7-2 for placing a cooling chip 5-1 is opened in the middle of the mounting plate 7-1. The charging component 3 is placed inside the mounting plate 7-1.

[0057] The primary purpose of the mounting plate 7-1 is to serve as a bridge connecting the charging component 3 and the heat dissipation system, providing an integrated mounting platform that neatly organizes key functional components such as the charging component 3 and the cooling element 5-1. The achieved technical effect is modular assembly and disassembly, facilitating production assembly and subsequent maintenance. Simultaneously, the rationally designed layout of the through holes 7-2 ensures an efficient heat transfer path from the charging component 3 to the cooling element 5-1, reducing heat loss. Furthermore, the fixing structure of the mounting plate 7-1 maintains precise relative positions between the components, eliminating displacement caused by vibration or external forces, and enhancing the stability and reliability of the entire system during use. The mounting plate 7-1 also supports and protects the charging component 3, preventing direct exposure to the external environment and extending the lifespan of the charging system. It also optimizes internal space utilization, making the entire phone holder structure more compact and lightweight.

[0058] The main purpose of the O-ring 6-1 design is to form a reliable sealing barrier at the interface where the mounting plate 7-1 contacts the first recess 22. The technical effect achieved is to effectively prevent external dust, moisture, and foreign objects from entering the internal circuit system, protecting the internal precision components from environmental pollution. At the same time, as an elastic element, the O-ring 6-1 can absorb vibration and impact during use, reducing wear caused by direct contact between hard materials. In addition, the O-ring 6-1 can also compensate for installation deviations and manufacturing tolerances, ensuring the stable positioning of the mounting plate 7-1 in the recess. Even when the equipment is subjected to external forces or temperature changes, it can maintain a tight fit between components, extend the service life of the equipment, and improve overall reliability.

[0059] In this embodiment, as Figure 4 , Figure 5 As shown, a second recess 23 is provided at the middle position inside the first recess 22, and the cooling chip 5-1 is embedded in the second recess 23 and the through hole 7-2 of the mounting plate 7-1.

[0060] In this embodiment, as Figure 4 , Figure 5 As shown, the charging assembly 3 includes a magnetic shielding sheet 31 to prevent reverse wireless transmission, a wireless charging coil 32, and a cover 33. The magnetic shielding sheet 31 covers the cooling plate 5-1, and the wireless charging coil 32 is surrounded on the magnetic shielding sheet 31. The cover 33 covers the magnetic shielding sheet 31 and the wireless charging coil 32. The magnetic shielding sheet 31, the wireless charging coil 32, and the cover 33 are all placed inside the mounting plate 7-1.

[0061] In this embodiment, as Figure 4 , Figure 5 As shown, the mounting plate 7-1 has a dividing ring 7-5 inside, dividing the interior of the mounting plate 7-1 into a first mounting area 7-3 and a second mounting area 7-4. A ring-shaped iron sheet 37 is installed in the first mounting area 7-3, and a magnetic inner ring 38 and a magnetic outer ring 39 with the same center are installed in front of the ring-shaped iron sheet 37. A magnetic shielding sheet 31 and a wireless charging coil 32 are installed inside the second mounting area 7-4. The cover 33 covers the mounting plate 7-1.

[0062] like Figure 4 As shown, the annular iron plate 37 in the first installation area 7-3, together with the magnetic inner ring 38 and the magnetic outer ring 39, forms a powerful magnetic fixing system that can firmly attract and fix mobile phones with magnetic functions, ensuring that the mobile phone will not fall off due to external force or vibration during charging, making the mobile phone fit tightly, improving the charging effect, and greatly improving the safety and stability of use.

[0063] The magnetic shielding sheet 31 in the second installation area 7-4 plays a crucial role in electromagnetic shielding, effectively preventing the electromagnetic field generated by the wireless charging coil 32 from leaking backward and concentrating the electromagnetic field for forward transmission. This improves charging efficiency and reduces potential electromagnetic interference to internal electronic components. The wireless charging coil 32 achieves optimal energy transfer efficiency through precise coaxial winding and a perfect match with the magnetic inner and outer rings.

[0067] In this embodiment, as Figure 3 As shown, a PCB circuit board 10 is mounted on the lower back of the front cover 2. The PCB circuit board 10 also has switches 1-4, which protrude from the back cover 1. The main purpose of the switches is to prevent the phone holder from continuously charging the phone if the user does not remove the phone during charging, which could lead to overcharging of the battery and affect battery life and safety. When the phone is fully charged or the user does not need the charging function temporarily, the charging function can be turned off, but the holder's fixing function can still be used to reduce unnecessary energy consumption. This control mechanism also reduces the extra heat generated by continuous charging, reduces the burden on the heat dissipation system, and further improves the energy efficiency and lifespan of the entire device.
