[0002] With the advancement of mobile phones, people have increasingly higher demands for the user experience and reliability of their devices. Therefore, it's essential to continuously improve the user experience across various mobile phone usage scenarios. As a crucial mobile phone accessory, the user experience of cooling back clips is becoming increasingly important. Currently, one of the main applications of existing cooling back clips is gaming. To achieve adequate heat dissipation, these clips often incorporate multiple vents. While this improves cooling capacity, when used during gameplay, the hot air blown onto the user's hands by the vents can negatively impact the user experience. Summary of the Invention

[0014] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0015] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0016] The heat dissipation back clip provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0017] Please refer to Figures 1 to 4This application provides a heat dissipation back clip, including a housing 600, a fan 5, a knob 1, a heat sink structure 200, and a linkage mechanism 300; the fan 5 is disposed within the housing 600; the knob 1 is connected to the linkage mechanism 300, and the heat sink structure 200 is connected to the linkage mechanism 300, the heat sink structure 200 being rotatably disposed within the housing 600; when the knob 1 rotates in a first direction, the linkage mechanism 300 drives the heat sink structure 200 to rotate in the first direction; when the knob 1 rotates in a second direction, the linkage mechanism 300 drives the heat sink structure 200 to rotate in the second direction; the linkage mechanism 300 drives the heat sink structure 200 to switch between a first air outlet state and a second air outlet state; the air outlet direction of the first air outlet state is different from the air outlet direction of the second air outlet state.

[0018] Understandably, the housing 600 of the heatsink back clip provides installation space for other components of the heatsink back clip, and its interior has a certain amount of accommodating space. The fan 5 is used to exhaust hot air or hot air from inside the heatsink back clip to the external environment. The knob 1 is connected to the linkage mechanism 300, and the knob 1 is used to drive the linkage mechanism 300 to move. The heat sink structure 200 is connected to the linkage mechanism 300, and the linkage mechanism 300 is used to drive the heat sink structure 200 to move. The heat sink structure 200 is used for heat dissipation and hot air exhaust. Under the action of the fan 5, it is used to exhaust the hot air or hot air from inside the heatsink back clip to the external environment in a specific direction, dissipating the heat generated inside the heatsink back clip to the external environment.

[0019] The heat sink structure 200 is rotatably disposed inside the housing 600. The rotatability includes, but is not limited to, rotatable connection structures such as shaft connection, ball joint connection, or hinge connection; this application does not specifically limit this. Rotating knob 1 in a first direction drives the linkage mechanism 300 to rotate the heat sink structure 200 in the first direction; rotating knob 1 in a second direction drives the linkage mechanism 300 to rotate the heat sink structure 200 in the second direction. The first direction is either clockwise or counterclockwise, and the second direction is the other. The airflow directions of the first and second airflow states are different. By rotating knob 1 clockwise or counterclockwise, the heat sink structure 200 can be switched between the first and second airflow states. After switching airflow states, the airflow direction of the heat sink structure 200 changes, which can change the airflow direction of the cooling back clip, reducing the amount of hot air or hot air blown onto the user's hand, thus improving the user experience of the cooling back clip. The fan 5 can be made of materials with good thermal conductivity, such as alloys or metals, and this application does not make any specific limitations.

[0020] Optionally, the heat dissipation back clip housing 600 has multiple air outlets on its side wall, which are spaced apart along the side wall of the housing 600.

[0021] Multiple air vents are located on the 600mm sidewall of the housing, corresponding to heat sinks. These vents connect the internal space of the cooling back clip to the external environment, allowing hot air to be expelled from the back clip to the outside environment under fan drive, thus improving heat exchange efficiency. The cooling back clip can also have an air inlet on the fan's intake side to draw air from the outside environment into the cooling back clip.

[0022] In some embodiments, please refer to Figure 2 The heat sink structure 200 includes a first heat sink group 210 and a second heat sink group 220; the first heat sink group 210 and the second heat sink group 220 are symmetrically arranged on both sides inside the housing 600; the first heat sink group 210 and the second heat sink group 220 are each composed of a number of heat sinks.

[0023] In the above embodiments, the heat sink structure 200 includes a first heat sink group 210 and a second heat sink group 220. Both the first and second heat sink groups 210 and 220 are composed of several heat sinks and are symmetrically arranged on both sides inside the housing 600. The first and second heat sink groups 210 and 220 are used to exhaust hot air from the heat sink back clip in different directions. Each heat sink in the first heat sink group 210 is parallel to each other, and each heat sink in the second heat sink group 220 is also parallel to each other. Each heat sink is rotatably disposed inside the heat sink back clip. This rotatability includes, but is not limited to, rotating connection structures such as gears, ball joints, and pins. The heat sinks are positioned corresponding to the air outlet. The heat sink material can be made of metals with good thermal conductivity, such as copper, steel, and aluminum, or other materials with good thermal conductivity. In specific operation, the heat generated by the device being cooled is transferred to the heat sink, and the heat on the heat sink exchanges heat with the air in the environment to achieve the function of cooling the device.

[0024] In some embodiments, please refer to Figure 1 The heat dissipation back clip housing 600 is composed of an upper housing 610 and a lower housing 620, which are closed to form a receiving cavity.

[0025] It is understood that the upper shell 610 and lower shell 620 of the heat dissipation back clip together constitute the shell 600 of the heat dissipation back clip and form a receiving cavity. The receiving cavity provides installation space for the internal components of the heat dissipation back clip, and the shell 600 has the function of physically protecting the internal components and preventing drops and impacts. The material of the heat dissipation back clip shell 600 can be made of materials such as plastic and fiber, and this application does not make specific limitations.

[0026] In some embodiments, please refer to Figure 2 and Figure 3The heat dissipation back clip has a partition 4 inside, which is located between the fan 5 and the lower housing 620. The linkage mechanism 300, the fan 5, the heat sink structure 200 and the knob 1 are located on the same side of the partition 4. The same side is the side away from the heat dissipation device when the heat dissipation back clip holds the heat dissipation device.

[0027] Understandably, the partition 4 provides a mounting base for the linkage mechanism 300, fan 5, heat sink structure 200, and knob 1. These components are positioned on the same side away from the device being cooled when held by the heat sink back clamp. The partition 4 can be made of alloys, aluminum, copper, or other metals with good thermal conductivity, or other materials with good thermal conductivity. The partition 4 has several fixing holes for securing the linkage mechanism 300, fan 5, heat sink structure 200, and knob 1 to the partition.

[0028] Optionally, the heat dissipation back clip includes a cooling chip (not shown in the figure), which is disposed between the partition 4 and the lower housing 620. The cooling chip is a thermoelectric cooling chip, which has a cold end and a hot end, with the hot end facing the fan 5 and the cold end facing the device being cooled.

[0029] Specifically, the thermoelectric cooling chip in the above embodiment, also known as a thermoelectric semiconductor cooling component or Peltier component, utilizes the Peltier effect. When direct current passes through a coupler composed of two different semiconductor materials connected in series, heat is absorbed and released at the two ends of the coupler, respectively, thereby achieving the purpose of cooling. The Peltier effect refers to the phenomenon that when current passes through a circuit composed of two different conductors, one conductor end absorbs heat and the other conductor end releases heat. Specifically, charge carriers in a P-type semiconductor absorb heat at the conductor end with higher potential energy before entering the P-type semiconductor, while charge carriers in an N-type semiconductor release heat at the conductor end with lower potential energy before entering the metal sheet. By controlling the direction of the current, cooling and heating effects can be achieved. The cold end of the thermoelectric cooling chip faces the device being cooled, used to dissipate heat from the device and absorb the heat generated by the device. The hot end faces the fan 5, used to transfer heat to the fan 5 through the partition 4, thereby achieving heat transfer and cooling of the device. A temperature difference is formed between the cold end and the hot end. The larger temperature difference between the cold end and the device being cooled accelerates the efficiency of heat transfer, thus improving the heat dissipation performance of the heat dissipation back clip.

[0030] Optionally, the linkage mechanism 300 of the heat dissipation back clip includes: a first linkage rod 310, a second linkage rod 320, a first rotating rod 330, a second rotating rod 340, and a heat sink connecting tube 350; the knob 1 is located at the bottom of the partition 4, the fan 5 is located in the middle of the partition 4, the first rotating rod 330 and the second rotating rod 340 are rotatably mounted on the partition 4, the first rotating rod 330 and the second rotating rod 340 are symmetrically arranged on both sides of the knob 1, and the first rotating rod 330 and the second rotating rod 340 rotate around the rod axis; the heat sink connecting tube 350 is arranged around the fan 5, and the heat sink structure 200 is connected in series, the first end of the heat sink connecting tube 350 is located on the same side as the first rotating rod 330, and the second end of the heat sink connecting tube 350 is located on the same side as the second rotating rod 340; the first linkage rod 310 is located between the first rotating rod 330 and the knob 1, and the second linkage rod 320 is located between the second rotating rod 340 and the knob 1.

[0031] Specifically, the first rotating rod 330 and the second rotating rod 340 are rotatably mounted on the partition 4. This rotatability includes, but is not limited to, rotatable connection structures such as pins, shafts, ball joints, hinges, and gears; this application does not specifically limit this. The heat sink connecting pipe 350 is used to connect each heat sink of the first heat sink group 210 and each heat sink of the second heat sink group 220 in series, causing the heat sink to rotate around its axis of rotation under the action of the heat sink connecting pipe 350. The knob 1 is used to drive the first linkage rod 310 and the second linkage rod 320, transmitting motion to the first rotating rod 330 and the second rotating rod 340. The first rotating rod 330 is used to drive the first end of the heat sink connecting pipe 350 to move, and the second rotating rod 340 is used to drive the second end of the heat sink connecting pipe 350 to move.

[0032] Optionally, knob 1 is rotatably connected to one side of the first linkage rod 310, knob 1 is rotatably connected to one side of the second linkage rod 320, the other side of the first linkage rod 310 is rotatably connected to the first rotating rod 330, the other side of the second linkage rod 320 is rotatably connected to the second rotating rod 340, the first rotating rod 330 is connected to the first end of the heat sink connecting tube 350, and the second rotating rod 340 is connected to the second end of the heat sink connecting tube 350.

[0033] In the above embodiment, the knob 1 drives the first linkage rod 310 and the second linkage rod 320, which in turn drive the first rotating rod 330 and the second rotating rod 340. The first rotating rod 330 and the second rotating rod 340 drive the heat sink structure 200 to switch between the first air outlet state and the second air outlet state through the heat sink connecting pipe 350.

[0034] For details, please refer to Figure 2 and Figure 4 ,by Figure 2Taking the state of the heat sink structure 200 as the first air outlet state as an example, when the knob 1 is rotated clockwise, it drives the first linkage rod 310 and the second linkage rod 320. The first linkage rod 310 drives the first rotating rod 330 to rotate counterclockwise. The first rotating rod 330 drives the first end of the heat sink connecting tube 350 to move towards the bottom of the partition 4. The heat sink connecting tube 350 drives the heat sink structure 200 to rotate clockwise around its rotation axis. The second linkage rod 320 drives the second rotating rod 340 to rotate counterclockwise. The second rotating rod 340 drives the second end of the heat sink connecting tube 350 to move towards the upper part of the partition 4. The heat sink connecting tube 350 drives the heat sink structure 200 to rotate clockwise around its rotation axis. Through the above movements, the heat sink connecting tube 350 rotates counterclockwise around the fan 5, finally forming the shape shown in the image. Figure 4 The second airflow state is shown. The airflow direction differs between the first and second airflow states; the second airflow state involves diagonal airflow. When the device being cooled is running demanding games, it generates significant heat. Users typically hold the device horizontally while gaming. When the cooling clip is in the first airflow state, the airflow from the side vents blows directly towards the user's hand, resulting in a poor user experience. Rotating knob 1 changes the airflow state from the first to the second, dispersing the airflow diagonally upwards and downwards. This reduces the amount of hot air blowing directly onto the user's hand, improving the user experience.

[0035] Optionally, the first linkage rod 310 and the second linkage rod 320 are rotatably connected to the knob 1 via ball joints, the first linkage rod 310 is rotatably connected to the first rotating rod 330 via ball joints, and the second linkage rod 320 is rotatably connected to the second rotating rod 340 via ball joints.

[0036] In the above embodiments, please refer to Figure 2 The knob 1 consists of an upper cylindrical structure and a lower cylindrical structure. The diameter of the upper cylindrical structure is larger than that of the lower cylindrical structure. Two spherical joints are provided on the lower cylindrical structure. The first linkage rod 310 and the second linkage rod 320 are both composed of two hemispherical cavities and a cylindrical connecting rod located in the middle. The hemispherical cavities and the spherical joints form a ball-joint rotation connection structure. The main body of the first rotating rod 330 and the second rotating rod 340 are both cylindrical structures. A square protrusion is provided on one side of the cylindrical structure. A spherical joint is provided on the symmetrical side of the square protrusion. The spherical joint and the hemispherical cavity of the linkage rod form a ball-joint rotation connection structure. A hole structure is provided on the square protrusion.

[0037] In some embodiments, please refer to Figure 3The heat sink connecting pipe 350 is composed of multiple hollow connecting pipes. A hollow connecting pipe is set between every two heat sinks. A transmission rope is set inside the multiple hollow connecting pipes to connect all the hollow connecting pipes in series.

[0038] Understandably, each heat sink has holes through which a transmission rope can pass, and the diameter of the heat sink connecting tube 350 is larger than the holes on the heat sink. The heat sink connecting tube 350 can be composed of several hollow connecting tube segments, each with a diameter larger than the holes on the heat sink. A hollow connecting tube segment is placed between every two heat sinks, with its two sides abutting against the two heat sinks, used to drive the heat sinks to rotate in a first or second direction under the action of the transmission rope. A transmission rope is installed inside the hollow connecting tube to transmit motion to each segment. Specifically, when the rotating rod rotates, it pulls the transmission rope inside the hollow connecting tube, which in turn drives the hollow connecting tube, causing the heat sinks to rotate. One end of the transmission rope is tied to the square protrusion hole of the first rotating rod 330, and the other end is tied near the ball joint of the second rotating rod 340.
