Description

Technical Field

[0001] This utility model relates to the field of heat dissipation metal plate technology, and in particular to quick-release heat dissipation metal plate. Background Technology

[0002] With the widespread adoption of the Internet of Things and mobile office and mobile entertainment, the average daily usage time of mobile phones, tablets and even foldable screen devices has soared from 3-4 hours in 2018 to 7-9 hours in 2024. Heavy users even exceed 12 hours. Such a high-intensity "online" state causes key chips such as SoC, GPU, baseband and charging IC to be under full or high load conditions for a long time, and heat accumulates rapidly inside the device.

[0003] To alleviate this pain point, "magnetic external heat dissipation metal plates" have been introduced on the market. They are usually made of 1-2 mm thick aerospace-grade 6063 aluminum or high-conductivity oxygen-free copper, with a black anodized or graphene coating on the surface. They use 8-16 N52 grade neodymium iron boron magnets to attract the metal coil or magnetic sheet on the back of the phone, forming a low thermal resistance channel that can reduce the temperature of hot spots by 6-10°C within 5 minutes. However, the magnetic structure itself has obvious shortcomings. The attraction force decreases exponentially with distance. When the user holds the phone with one hand or puts it in a pocket, even a slight lateral shear force can cause the magnets to misalign. In sports scenarios (cycling, running) or accidental collisions with a table, the metal plate can easily fall off with a "snap", causing scratches, loss, or even injury to the instep. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-release heat dissipation metal plate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick-release heat dissipation metal plate, comprising a metal plate, a magnetic ring on the back of the metal plate, sockets on both sides of the magnetic ring, the sockets and the metal plate being detachably connected, a sliding rod being slidably connected through the side of the socket, a limit protrusion being fixed at one end of the sliding rod, a U-shaped clamp being fixed at the other end of the sliding rod, and an adjusting spring being provided between the limit protrusion side and the socket side.

[0006] Preferably, the metal plate has a plug fixedly arranged on its back, and the socket has a slot on the side near the metal plate. The upper and lower inner walls of the slot have engaging grooves, and engaging sliders are slidably connected within each engaging groove. Engaging springs are fixed between the side of the engaging sliders located within the same engaging groove that is furthest from each other and between the sidewall of the engaging groove. Engaging rollers are provided between the engaging sliders located within different engaging grooves. Existing heat dissipation metal plates experience reduced lifespan after prolonged use and are inconvenient to disassemble and replace. To address this problem, this invention adopts a quick-disassembly structure. For replacement, simply unplug the plug. For installation, insert the plug from the back of the metal plate into the socket slot. The plug presses against the engaging rollers and engaging springs. Once the plug is fully inserted into the slot, the engaging rollers hold the plug in place to prevent the metal plate from falling off. This simplifies disassembly and assembly and improves replacement efficiency.

[0007] Preferably, the inner wall of the U-shaped clamp is provided with multiple clamping grooves, and each clamping groove is slidably connected with a clamping protrusion. A clamping spring is fixed between one side of the clamping protrusion and the side wall of the clamping groove. In order to further improve the tightness between the U-shaped clamp and the mobile phone, this utility model adopts a clamping structure. When the mobile phone and the U-shaped clamp come into contact, the clamping protrusion is squeezed and tightly pressed against the surface of the mobile phone under the action of the clamping spring, thereby improving the stability between the metal plate and the mobile phone.

[0008] Preferably, the other side of the clamping protrusion is hemispherical to facilitate the insertion of the mobile phone into the U-shaped clamp.

[0009] Preferably, the plug surface has a locking groove, and both ends of the plug end are designed as arc surfaces. The locking groove facilitates the engagement of the locking roller and the plug, and the arc surface design facilitates the plug entering the slot.

[0010] Preferably, both ends of the engaging roller are fixedly connected to the engaging slider, and the fixed connection further improves the biting force between the engaging roller and the locking groove.

[0011] Preferably, the clamping protrusion is hemispherical with a rubber sleeve nested at one end. The rubber sleeve increases the friction between the clamping protrusion and the surface of the mobile phone, further improving the clamping force between the clamping protrusion and the mobile phone. Beneficial effects

[0012] To alleviate this pain point, existing technologies have introduced "magnetic external heat dissipation metal plates" on the market. These are typically made of 1-2 mm thick aerospace-grade 6063 aluminum or high-conductivity oxygen-free copper, with a black anodized or graphene coating. They utilize 8-16 N52-grade neodymium iron boron magnets to attract the phone's metal coil or magnetic strip, forming a low thermal resistance channel that keeps the hotspot temperature below 5°C. The temperature drops by 6-10℃ within minutes. However, the magnetic structure itself has obvious shortcomings. The attraction force decreases exponentially with distance. When the user holds the phone with one hand or puts it in a pocket, even a slight lateral shear force can cause the magnet to misalign. In motion or accidental collisions on a table, the metal plate can easily fall off with a "snap," causing scratches, loss, or even injury to the instep. To address these issues, this invention uses an interlocking heat dissipation metal plate that adapts to different phone sizes. When in use, the phone and magnetic ring are attached, and the U-shaped clamp is slid outward until it matches the width of the phone's sides. Under the action of the adjusting spring, the U-shaped clamp clamps the sides of the phone, preventing the metal plate from falling off due to reduced attraction force or accidental contact during movement. The metal plate is also detachable for easy replacement. To replace it, simply unplug the plug. To install it, insert the plug on the back of the metal plate into the socket slot. The plug presses against the locking roller and locking spring. After the plug is fully inserted into the slot, the locking roller holds the plug in place to prevent the metal plate from falling off. The simple assembly and disassembly improves replacement efficiency. Attached Figure Description

However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0016] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation

[0017] Reference Figure 1-8 The quick-release heat dissipation metal plate includes a metal plate 1, a magnetic ring 4 on the back of the metal plate 1, and sockets 2 on both sides of the magnetic ring 4. The sockets 2 and the metal plate 1 are detachably connected. A slide rod 5 is slidably connected through the side of the socket 2. A limit protrusion 7 is fixed at one end of the slide rod 5, and a U-shaped clamp 3 is fixed at the other end of the slide rod 5. An adjustment spring 6 is provided between one side of the limit protrusion 7 and one side of the socket 2.

[0018] A plug 13 is fixedly arranged on the back of the metal plate 1. A locking groove 1301 is formed on the surface of the plug 13. Both ends of the plug 13 are curved. The locking groove 1301 facilitates the engagement of the locking roller 8 and the plug 13, and the curved design facilitates the insertion of the plug 13 into the slot 201. A slot 201 is formed on the side of the socket 2 near the metal plate 1. Engaging grooves 2011 are formed on both the upper and lower inner walls of the slot 201. Engaging sliders 9 are slidably connected in an array inside the engagement grooves 2011. Engaging springs 10 are fixed between the side of the engaging sliders 9 located in the same engagement groove 2011 that are furthest from each other and the side wall of the engagement groove 2011. Engaging rollers 8 are provided between the engaging sliders 9 located in different engagement grooves 2011. Existing heat dissipation metal plates have a reduced lifespan after prolonged use and are inconvenient to disassemble and replace. To address this issue, this utility model employs a quick-disassembly and assembly structure. During replacement, simply unplug the plug 13. During installation, insert the plug 13 on the back of the metal plate 1 into the slot 201 of the socket 2. The plug 13 presses against the engaging roller 8 and the engaging spring 10. Once the plug 13 is fully inside the slot 201, the engaging roller 8 holds the plug 13 in place to prevent the metal plate 1 from falling off. This simple disassembly and assembly process improves replacement efficiency. Both ends of the engaging roller 8 are fixedly connected to the engaging slider 9, which further enhances the engagement force between the engaging roller 8 and the locking groove 1301.

[0019] The inner wall of the U-shaped clamp 3 has multiple clamping grooves 301, and each clamping groove 301 is slidably connected to a clamping protrusion 11. A clamping spring 12 is fixed between one side of the clamping protrusion 11 and the side wall of the clamping groove 301. To further improve the tightness between the U-shaped clamp 3 and the mobile phone, this utility model adopts a clamping structure. When the mobile phone and the U-shaped clamp 3 come into contact, the clamping protrusion 11 is squeezed, and under the action of the clamping spring 12, it tightly presses against the surface of the mobile phone, improving the stability between the metal plate 1 and the mobile phone. The other side of the clamping protrusion 11 is hemispherical, which facilitates the entry of the mobile phone into the U-shaped clamp 3. A rubber sleeve is nested at the hemispherical end of the clamping protrusion 11. The rubber sleeve increases the friction between the clamping protrusion 11 and the surface of the mobile phone, further improving the clamping force between the clamping protrusion 11 and the mobile phone.

[0020] The working principle of this utility model is as follows: The U-shaped clamp 3 is slid outward until it matches the width of the two sides of the mobile phone. Under the action of the adjusting spring 6, the U-shaped clamp 3 clamps the two sides of the mobile phone, preventing the metal plate 1 from falling off due to reduced adsorption force or accidental contact during movement. When the mobile phone comes into contact with the U-shaped clamp 3, the clamping protrusion 11 is squeezed and clamped. Under the action of the clamping spring 12, it is tightly pressed against the surface of the mobile phone. The metal plate 1 is also detachable for easy replacement. When replacing, simply unplug the plug 13. When installing, insert the plug 13 on the back of the metal plate 1 into the slot 201 of the socket 2. The plug 13 squeezes the locking roller 8 and the locking spring 10. After the plug 13 is fully inserted into the slot 201, the locking roller 8 presses against the plug 13 to prevent the metal plate 1 from falling off.
