Description

Technical Field

[0001] This utility model belongs to the field of mobile phone holders, specifically a cooling and heat dissipation type wireless charging mobile phone holder. Background Technology

[0002] In daily use, phone holders combined with wireless charging have become a mainstream requirement, especially in in-car scenarios, where users often use holders to wirelessly charge their phones while navigating and making calls. However, the energy conversion during wireless charging generates a significant amount of heat, which is exacerbated by high-power operations such as navigation and video playback. In the summer in-car environment, the temperature near the center console is already high, further aggravating the overheating problem of phones.

[0003] Most existing wireless charging phone holders rely solely on passive heat sinks or small fans for heat dissipation, lacking active cooling methods. Passive cooling struggles to quickly dissipate heat in high-temperature environments, while fan cooling is limited by the internal space of the holder, resulting in low airflow and susceptibility to ambient temperature fluctuations, leading to inefficient heat dissipation. This causes phones to frequently trigger overheating alarms during continuous charging and use, significantly reducing charging speed, potentially impacting battery life due to high temperatures, and even posing safety hazards, failing to meet users' demands for efficient heat dissipation and stable charging.

A clamping assembly 2 is disposed inside the shell 1, including a transmission unit 201 and two clamping arms 202 that move along the X-axis. The transmission unit 201 drives the clamping arms 202 to move towards or away from each other. A lower support assembly 3 is disposed on the lower edge of the front side of the shell 1, including a lower support arm 301 that moves along the Y-axis and a positioning unit 302. The positioning unit 302 locks the position of the lower support arm 301; the cooling component 4 is located inside the outer shell 1 at the center of the front shell 102, including a cooling plate 401 and a heat insulation plate 402, wherein the cooling surface of the cooling plate 401 is in contact with the protective plate 9; the heat dissipation component 6 is located inside the outer shell 1 at the heating surface of the cooling plate 401, including a heat dissipation plate 601 and a fan 602; the wireless charging coil 7 is fixed inside the front shell 102 and electrically connected to an external power source; the locking component 5 is located inside the outer shell 1 and cooperates with the transmission unit 201 to lock the position of the clamping arm 202.

[0034] Both the rear shell 101 and the front shell 102 of the outer casing 1 are made of ABS engineering plastic and are connected by four M3 screws to form the internal storage space. They are lightweight and impact-resistant. The protective plate 9 embedded on the front of the front shell 102 is made of silicone and is 0.5mm thick. It covers the corresponding surface of the cooling chip 401 to prevent the phone from directly contacting the front shell 102 and causing scratches. The ball joint seat 8 at the center of the back of the rear shell 101 is integrally formed and has a rotation angle range of 0-360 degrees. It can be connected to a car air vent bracket or desktop bracket to achieve multi-angle adjustment. The transmission unit 201 of the clamping assembly 2 is mounted on the protruding shaft inside the rear shell 101 via bearings. The two clamping arms 202 are symmetrically distributed, and their extension ends pass through the strip hole of the front shell 102. A 1mm thick anti-slip silicone pad with a grid pattern is pasted on the inside. The lower support arm 301 of the lower support assembly 3 is inserted into the lower edge groove of the front shell 102, and the guide plate 3012 is welded and fixed to the lower support plate 3011. The cooling component 4 uses a 5-10W semiconductor cooling chip 401, with its cooling surface adhered to the inside of the front shell 102 via thermally conductive silicone. The insulation sheet 402, made of 2mm thick polyurethane foam, wraps around the sides of the cooling chip 401 and is secured with tape. The heat dissipation component 6 uses an aluminum alloy heat sink 601, fixed to the heating surface of the cooling chip 401 with four M2 screws. It features heat dissipation fins on its surface. The fan 602 is a DC brushless fan, mounted on the outside of the heat sink 601 via clips, with operating noise below 30dB. The wireless charging coil 7 supports the Qi protocol, with a power output of 15W. It is fixed to the inside of the front shell 102 above the cooling chip 401 using double-sided tape. A charging port for connection is located on the side of the outer shell 1. The locking component 5 uses a latch 501 hinged to the inside of the rear shell 101 via a pin. The slider 502 is inserted through a sliding hole in the side wall of the outer shell 1, with its outer end protruding 5-8mm.

[0035] During operation, the operator first secures the bracket to the support structure using the ball joint 8, adjusting it to a tilt angle of 60-75 degrees. Next, the lower support assembly 3 and clamping assembly 2 are adjusted to secure the phone according to its size. Finally, an external power source is connected, activating the wireless charging coil 7, cooling assembly 4, and heat dissipation assembly 6. Through a combination of active cooling and efficient heat dissipation, the phone's temperature is quickly reduced, preventing overheating from affecting charging and usage.

[0036] As attached Figure 2 To be continued Figure 3 As shown: In one embodiment of the present invention, the transmission unit 201 includes a drive gear 2011 and a positioning gear 2012 that mesh with each other, and the clamping arm 202 is provided with a transmission tooth groove 203 that meshes with the drive gear 2011, and a return spring is provided between the clamping arm 202 and the outer shell 1.

[0037] The drive gear 2011 and the positioning gear 2012 are coaxially fixed and both adopt a helical tooth structure. The transmission tooth groove 203 is also helical. The meshing of the two enhances the transmission stability and reduces the shaking of the clamping arm 202. One end of the return spring is connected to one of the clamping arms 202, and the other end abuts against the inner side of the rear shell 101, providing the return force for the clamping arm 202.

[0038] During operation, the operator first pushes the clamping arm 202, driving the gear 2011 to rotate and causing the two clamping arms 202 to move in opposite directions. After release, the return spring pulls the clamping arm 202 back to its original position, and the drive gear 2011 rotates in the opposite direction, causing the two clamping arms 202 to move towards each other. Through the gear transmission and the cooperation of the return spring, the clamping arm 202 can be precisely opened and closed to accommodate mobile phones of different widths.

[0039] As attached Figure 2 To be continued Figure 3 As shown: In one embodiment of the present invention, the locking component 5 includes a pawl 501 hinged to the rear shell 101, a slider 502 sliding through the outer shell 1, and a reset element 503. One end of the pawl 501 is provided with teeth that mesh with the positioning gear 2012, and the other end is connected to the reset element 503. The inner end of the slider 502 abuts against the pawl 501.

[0040] The pawl 501 is hinged to a preset position on the rear shell 101 via a pin. The reset element 503 is a torsion spring, with one end fixing the pawl 501 away from the toothed end and the other end fixed to the protruding post on the rear shell 101. A guide structure is provided between the slider 502 and the outer shell 1 to ensure smooth sliding.

[0041] During operation, the operator first presses the slider 502, causing its inner end to push the chuck 501 to rotate around the pin, disengaging the teeth of the chuck 501 from the positioning gear 2012. After adjusting the clamping arm 202, the operator releases the slider 502, and the reset element 503 pulls the chuck 501 back to its original position, re-engaging and locking the teeth with the positioning gear 2012. The engagement of the chuck 501 with the positioning gear 2012 ensures the stability of the clamping arm 202, preventing it from loosening due to vibration.

[0042] As attached Figure 2 To be continued Figure 4 As shown: In one embodiment of the present invention, the lower support arm 301 includes a lower support plate 3011 and a guide plate 3012. The lower support plate 3011 is slidably disposed in the sliding groove of the front shell 102. The guide plate 3012 is connected to the lower support plate 3011. The lower support plate 3011 is provided with a plurality of positioning grooves.

[0043] The upper surface of the lower support plate 3011 is provided with anti-slip texture to increase the friction with the bottom of the mobile phone. Several lower support plates 3011 are welded and fixed to the bottom surface of the guide plate 3012. The guide plate 3012 extends along the Y-axis into the inside of the outer shell 1 for easy manual adjustment.

[0044] During operation, the operator first pulls or pushes the guide plate 3012, causing the lower support plate 3011 to slide along the groove of the front shell 102; after adjusting to the appropriate position, it is locked by the positioning unit 302. The lower support plate 3011 can be adjusted by sliding to accommodate the bottom support needs of mobile phones of different lengths.

[0045] As attached Figure 4 As shown: In one embodiment of the present invention, the positioning unit 302 includes an elastic element 3021 and a positioning block 3022, wherein the positioning block 3022 cooperates with the positioning groove of the lower support plate 3011.

[0046] The elastic element 3021 is a compression spring, with one end welded to the inner boss of the front shell 102 and the other end welded to the positioning block 3022. The positioning block 3022 is perpendicular to the surface of the lower support plate 3011, and the positioning grooves on the side of the lower support plate 3011 are spaced 5mm apart to accommodate mobile phone supports of different sizes.

[0047] During operation, the operator first adjusts the lower support plate 3011, causing the positioning block 3022 to retract under pressure, compressing the elastic element 3021. When it slides to the target position, the positioning block 3022 pops out under the action of the elastic element 3021 and engages with the positioning groove. Through the cooperation between the positioning block 3022 and the positioning groove, the position of the lower support arm 301 is stably locked.

[0048] As attached Figure 4 To be continued Figure 5As shown: In one embodiment of the present invention, the heat insulation sheet 402 wraps around the side and back of the cooling sheet 401 and is located between the front shell 102 and the cooling sheet 401. The front shell 102 is provided with a notch groove corresponding to the heat sink 601. The heat sink 601 is partially exposed in the notch groove. The side and back of the outer shell 1 are provided with heat dissipation holes corresponding to the fan 602.

[0049] The insulation sheet 402 completely covers the sides and back of the cooling fin 401, reducing the diffusion of cold energy to other areas inside the outer casing 1 and lowering cold energy loss. The notch in the front casing 102 exposes part of the heat sink 601, enhancing the heat dissipation effect. The heat dissipation holes on the sides and back of the outer casing 1 correspond to the air outlet of the fan 602, accelerating air circulation.

[0050] During operation, the cooling element 401 activates first, while the insulation element 402 prevents cold air from dissipating. Simultaneously, the fan 602 starts, expelling hot air through the heat dissipation holes, and the exposed portion of the heat sink 601 further assists in heat dissipation. This combination of insulation and heat dissipation structures improves cooling efficiency and ensures sufficient heat dissipation.

[0051] As attached Figure 1 To be continued Figure 5 As shown: In one embodiment of the present invention, the clamping arm 202 and the lower support plate 3011 both extend to the outside of the front shell 102, and an anti-slip silicone pad is provided on the inner side of the extended end.

[0052] The extension length of the clamping arm 202 is adapted to the width of common mobile phones, and the extension length of the lower support plate 3011 meets the bottom support requirements of the mobile phone. The anti-slip silicone pad is 1mm thick with a grid pattern on the surface to increase friction with the mobile phone.

[0053] During operation, the phone is first placed on the protective plate 9, and the extended ends of the clamping arms 202 clamp the phone from both sides, while the extended ends of the lower support plate 3011 support the phone from the bottom. Anti-slip silicone pads increase friction to prevent the phone from slipping when tilted or vibrating.

[0054] As attached Figure 5 As shown: In one embodiment of this utility model, the wireless charging coil 7 is located above the cooling chip 401, and the side of the housing 1 is provided with a charging interface connected to the wireless charging coil 7.

[0055] The wireless charging coil 7 and the cooling chip 401 are staggered to avoid mutual interference. Its leads are soldered to the internal power module. The charging interface is a Type-C interface, which is installed in the reserved hole on the side of the outer casing 1 for easy connection to an external power source.

[0056] During operation, an external power source is first connected through the charging interface, and current is transmitted to the wireless charging coil 7. After the phone is placed on the coil, the wireless charging coil 7 generates an electromagnetic field to wirelessly charge the phone. Through reasonable layout and interface settings, a stable wireless charging function is achieved.

[0057] Working principle: The bracket is fixed to the vehicle air vent or desktop support structure by ball joint seat 8. Adjust the angle of ball joint seat 8 so that the support surface of the front shell 102 is at an angle that is easy to view and operate (60-75 degrees recommended).

[0058] Depending on the size of the phone, the lower support plate 3011 is pulled outward or pushed inward. The positioning block 3022 pops out or retracts under the action of the elastic element 3021. When the positioning block 3022 is inserted into the target positioning groove, the position of the lower support arm 301 is locked to ensure that the bottom of the phone is stably supported.

[0059] Press the slider 502 on the side of the outer casing 1. The inner end of the slider 502 pushes the pawl 501 to rotate around the pin shaft. The teeth of the pawl 501 disengage from the positioning gear 2012. Push one clamping arm 202 to move, which in turn drives the gear 2011 to drive the two clamping arms 202 to move in opposite directions along the X-axis, increasing the distance between the clamping arms 202. Place the mobile phone on the support surface, with the bottom of the mobile phone resting on the lower support plate 3011 and the back side in contact with the protective sheet 9.

[0060] Release the push on the clamping arm 202, the return spring pushes the clamping arm 202 to reset, and the drive gear 2011 drives the two clamping arms 202 to move towards each other until the anti-slip silicone pads of the clamping arms 202 are in close contact with both sides of the mobile phone; release the slider 502, and under the action of the reset element 503, the pawl 501 resets, the teeth re-mesh with the positioning gear 2012, and the position of the clamping arm 202 is locked to prevent the mobile phone from loosening.

[0061] When an external power source is connected via the charging interface, the wireless charging coil 7 is activated to provide wireless charging for the mobile phone. At the same time, the cooling chip 401 is powered on and the cooling surface conducts cold energy to the mobile phone through the front shell 102 and the protective sheet 9 to reduce the temperature of the mobile phone. The heat preservation sheet 402 reduces the diffusion of cold energy into the inner shell 1, ensuring that the cold energy is concentrated on the mobile phone.

[0062] The heat generated by the heating surface of the cooling chip 401 is absorbed by the heat sink 601. The fan 602 starts and exhausts the hot air around the heat sink 601 through the heat dissipation holes on the side of the outer casing 1, accelerating heat dissipation and preventing the cooling chip 401 from becoming inefficient due to overheating.

[0063] Press slider 502 to unlock clamping assembly 2, turn manual knob to open clamping arm 202 and remove the phone; turn off the power, and cooling chip 401 and fan 602 stop working.

[0064] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
