Description

Technical Field

[0001] The utility model relates to the technical field of wireless charging, in particular to a portable wireless charger with sufficient heat dissipation. Background Art

[0002] With the development of wireless charging technology, more and more electronic devices adopt wireless charging. For example, when a mobile phone or a tablet computer is internally provided with a charging coil and a wireless charger is used for wireless charging, the device to be charged is stacked on the wireless charger, so that the charging coil is aligned with the coil in the wireless charger. Thus, the wireless charger can transfer energy to the charging coil of the device to be charged through electromagnetic conversion via the internal coil, thereby realizing wireless charging of the device to be charged. There is no need to connect to a power socket through a wire, and the user only needs to place the device on the charging board of the charger to charge.

[0003] In the prior art, when using a wireless charger to power a mobile phone, since the angle of the wireless charger is fixed, it cannot meet the usage requirements of different customers and affects the user's viewing experience. Therefore, in order to improve the application scenarios of the wireless charger, an adjustable base is usually provided for the wireless charger to adjust the angle of the wireless charger. However, such a wireless charger usually can only adjust the angle in one direction, which limits the flexibility of the usage scenario and cannot meet the user's need to view the mobile phone screen from different angles when watching videos or making video calls. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a portable wireless charger with sufficient heat dissipation is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a portable wireless charger with sufficient heat dissipation, including a base, one end of the base is rotatably connected with a charging panel, a charging module is arranged in the middle of the charging panel, the top of the charging module is set as an electromagnetic induction area, an installation groove is opened in the middle of the charging panel, limiting sliding grooves are arranged in an array on the inner wall of the installation groove, limiting columns are slidably connected in the limiting sliding grooves, a limiting spring is fixed between the limiting columns and the limiting sliding grooves, and the end of the limiting column is spherical. A limiting ring is arranged on the outer wall of the charging module, and the limiting ring is rotatably connected with the installation groove. Spherical grooves are arranged in an array on the outer wall of the charging module, and the spherical grooves are arranged between the limiting rings, and the groove diameter of the spherical grooves is not less than the ball diameter of the end of the limiting column.

[0006] Preferably, a square groove is formed at the bottom end of the charging panel. A rotating shaft is rotatably connected to the side wall of the square groove. A support seat is fixed on the surface of the rotating shaft. Damping gaskets are provided between both sides of the support seat and the side wall of the square groove, and the damping gaskets are nested on the surface of the rotating shaft. When the weight of the mobile phone is large, it is easy for the back of the mobile phone to loosen at the magnetic attraction part of the charging module during operation of the mobile phone. To solve such problems, the present utility model is provided with a support seat at the bottom end of the charging panel. The support seat is pulled out with a finger, and the damping gasket provides a large friction force to prevent the support seat from loosening, playing a certain supporting role for the bottom of the mobile phone and improving the stability of the mobile phone.

[0007] Preferably, a rotating handle is fixed at the bottom of the charging module. Anti-slip patterns are arranged in an array on the surface of the rotating handle, which is convenient for rotating the charging module, thereby facilitating the adjustment of the angle of the mobile phone.

[0008] Preferably, a storage groove is formed at the top of the base, which is convenient for storing the charging panel, reducing the volume of the wireless charger and facilitating carrying.

[0009] Preferably, a through hole is formed in the middle of the storage groove to reserve a storage space for the rotating handle.

[0010] Preferably, a rubber pad is bonded to the side wall of the storage groove. The rubber pad increases the friction force between the charging panel and the side wall of the storage groove, improving the stability of the charging panel after being stored in the base and preventing the charging panel from rotating when it is inverted.

[0011] Preferably, heat dissipation fins are bonded to the surface of the charging panel. When the mobile phone is wirelessly charged, a large amount of heat will be generated. To solve such problems, the present utility model uses heat dissipation fins to improve the heat dissipation effect of the charging panel.

[0012] Beneficial effects

[0013] In the prior art, when using a wireless charger to power a mobile phone, since the angle of the wireless charger is fixed, it cannot meet the usage requirements of different customers and affects the user's viewing experience. Therefore, to improve the application scenarios of the wireless charger, an adjustable base is usually provided for the wireless charger to adjust the angle of the wireless charger. However, such a wireless charger can usually only adjust the angle in one direction, which limits the flexibility of the usage scenario. When watching a video or making a video call, it cannot meet the user's need to view the mobile phone screen from different angles. To address such problems, the present utility model adopts a rotating mechanism to adjust the angle between the base and the charging panel. Place the mobile phone on the surface of the charging panel, and the internal charging coil of the mobile phone fits with the electromagnetic induction area for charging. When it is necessary to horizontally place the mobile phone or adjust the angle of the mobile phone, rotate the rotating handle, driving the charging module to rotate in the installation groove to a suitable angle. When rotating, the outer wall of the charging module presses against the limiting column, driving the limiting column to press against the limiting spring in the limiting chute. After rotating to a suitable angle, align the spherical groove with the limiting column, and under the action of the limiting spring, the end of the limiting column abuts against the spherical groove to prevent the charging module from rotating, fixing the angle, improving the stability of the mobile phone, meeting the user's need to view the mobile phone screen from different angles, and improving the flexibility of the usage scenario of the wireless charger.

A heat sink 302 is adhesively bonded to the surface of the charging panel 3. When the mobile phone is wirelessly charged, a large amount of heat will be generated. To address such problems, the present utility model uses the heat sink 302 to improve the heat dissipation effect of the charging panel 3. A charging module 12 is provided in the middle of the charging panel 3. The top of the charging module 12 is set as an electromagnetic induction area 4. An installation groove is opened in the middle of the charging panel 3. Limiting sliding grooves 301 are array - opened on the inner wall of the installation groove. A limiting post 8 is slidably connected inside the limiting sliding grooves 301. A limiting spring 7 is fixed between the limiting post 8 and the limiting sliding grooves 301, and the end of the limiting post 8 is spherical. A limiting ring 13 is provided on the outer wall of the charging module 12, and the limiting ring 13 is rotatably connected to the installation groove. Spherical grooves 1201 are array - opened on the outer wall of the charging module 12, and the spherical grooves 1201 are arranged between the limiting rings 13, and the groove diameter of the spherical grooves 1201 is not less than the ball diameter of the end of the limiting post 8. A rotating handle 14 is fixed to the bottom of the charging module 12. Anti - slip patterns are array - opened on the surface of the rotating handle 14, which is convenient for rotating the charging module 12, thereby facilitating the adjustment of the angle of the mobile phone.

[0026] A square groove is opened at the bottom end of the charging panel 3. A rotating shaft 9 is rotatably connected to the side wall of the square groove. A support seat 10 is fixed to the surface of the rotating shaft 9. Damping gaskets 11 are provided between both sides of the support seat 10 and the side wall of the square groove, and the damping gaskets 11 are nested on the surface of the rotating shaft 9. When the weight of the mobile phone is large, it is easy for the back of the mobile phone to become loose at the magnetic attraction part with the charging module 12 during operation. To address such problems, the present utility model provides a support seat 10 at the bottom end of the charging panel 3. When the support seat 10 is pulled out with a finger, the damping gasket 11 provides a large frictional force to prevent the support seat 10 from loosening, playing a certain supporting role for the bottom of the mobile phone and improving the stability of the mobile phone.

[0027] A storage groove 2 is provided at the top of the base 1, which is convenient for storing the charging panel 3, reducing the volume of the wireless charger and making it easy to carry. A through hole 5 is provided in the middle of the storage groove 2 to reserve a storage space for the rotating handle 14. A rubber pad 6 is bonded to the side wall of the storage groove 2. The rubber pad 6 increases the friction between the charging panel 3 and the side wall of the storage groove 2, improving the stability of the charging panel 3 after being stored with the base 1 and preventing the charging panel 3 from rotating when it is inverted.

[0028] In the prior art, when using a wireless charger to power a mobile phone, since the angle of the wireless charger is fixed, it cannot meet the usage requirements of different customers and affects the user's viewing experience. Therefore, to improve the application scenarios of the wireless charger, an adjustable base is usually provided for the wireless charger to adjust the angle of the wireless charger. However, this type of wireless charger usually can only adjust the angle in one direction, restricting the flexibility of the usage scenario. When watching videos or making video calls, it cannot meet the user's need to view the mobile phone screen from different angles. To address such problems, the present utility model adopts a rotating mechanism to adjust the angle between the base 1 and the charging panel 3. Place the mobile phone on the surface of the charging panel 12, and the charging coil inside the mobile phone fits with the electromagnetic induction area 4 for charging. When it is necessary to horizontally place the mobile phone or adjust the angle of the mobile phone, rotate the rotating handle 14, driving the charging module 12 to rotate in the installation groove to a suitable angle. When rotating, the outer wall of the charging module 12 squeezes the limit post 8, driving the limit post 8 to squeeze the limit spring 7 in the limit chute 301. After rotating to a suitable angle, align the spherical groove 1201 with the limit post 8, and under the action of the limit spring 7, the end of the limit post 8 abuts against the spherical groove 1201 to prevent the charging module 12 from rotating and fix the angle, improving the stability of the mobile phone and meeting the user's need to view the mobile phone screen from different angles, enhancing the flexibility of the usage scenario of the wireless charger.

[0029] The working principle of the present utility model: Adjust the angle between the base 1 and the charging panel 3. Place the mobile phone on the surface of the charging panel 12, and the charging coil inside the mobile phone fits with the electromagnetic induction area 4 for charging. When it is necessary to horizontally place the mobile phone or adjust the angle of the mobile phone, rotate the rotating handle 14, driving the charging module 12 to rotate in the installation groove to a suitable angle. When rotating, the outer wall of the charging module 12 squeezes the limit post 8, driving the limit post 8 to squeeze the limit spring 7 in the limit chute 301. After rotating to a suitable angle, align the spherical groove 1201 with the limit post 8, and under the action of the limit spring 7, the end of the limit post 8 abuts against the spherical groove 1201 to prevent the charging module 12 from rotating and fix the angle. When the mobile phone is placed vertically, use your finger to pull out the support seat 10. The damping gasket 11 provides a large friction force to prevent the support seat 10 from loosening. Without affecting charging, move the mobile phone to the top of the support seat 10 to provide a certain supporting effect on the bottom of the mobile phone.
