Description

Technical Field

[0001] This invention belongs to the field of wireless chargers, specifically relating to a three-in-one wireless charger. Background Technology

[0002] With the rapid development of mobile communication devices and the significant improvement in device performance, the demand for electrical energy is also increasing. In order to adapt to different usage needs, the charging methods of devices have also changed.

[0003] Currently, most wireless chargers for mobile phones generate high temperatures during use, making them prone to malfunction in hot weather. Furthermore, when the charger is not in use, dust can easily accumulate on the motherboard and coils inside the charger after slotting, leading to charging failures. Additionally, existing chargers with slots create numerous stress points, making them susceptible to damage to the internal motherboard if the charger accidentally slips, rendering it unusable. Therefore, we have made improvements and proposed a three-in-one wireless charger. Summary of the Invention

[0004] The above-mentioned objective of this invention is achieved through the following technical solutions: A three-in-one wireless charger includes: a flexible outer shell and a rigid inner shell. The rigid inner shell is an elliptical cylindrical structure with through slots in the middle and at the top and bottom. A circuit board is fixed inside the rigid inner shell. A wireless coil is fixed on the upper layer of the rigid inner shell and connected to the circuit board. A sliding groove is also formed on the upper layer of the rigid inner shell. A limit post is provided inside the sliding groove. Soft rubber deformation blocks are respectively provided on the left and right sides of the rigid inner shell. The soft rubber deformation blocks contact the flexible outer shell outward. A push rod is connected inward to the soft rubber deformation block. A push block is connected to the other end of the push rod. A rotating column is provided inside the push block. An auxiliary deformation rod is connected to the rotating column.

[0005] Preferably, the soft rubber deformable block is made of a relatively heavy plastic material, and the left soft rubber deformable block is a solid structure, so that the center of gravity of the wireless charger is biased to the left.

[0006] Preferably, the flexible outer shell is made of a flexible deformable plastic material, and a ventilation window is opened in the middle of the flexible outer shell. At the same time, ventilation grilles are provided at the top and bottom of the flexible outer shell, and a deformable ventilation net is fixedly connected to the ventilation window.

[0007] Preferably, the auxiliary deformation rod includes a connecting rod, one end of which is rotatably connected to the rotating column, a slide rail groove is provided in the middle of the connecting rod, the limiting column can move within the slide rail groove, and a rotating push block is connected to the other end of the connecting rod, the rotating push block can rotate at an angle on the connecting rod and move together with the connecting rod at the same time.

[0008] Preferably, a USB window is provided on the right side of the flexible outer shell, and a miniature fan is provided on the left side of the flexible outer shell. The miniature fan is connected to the circuit board. A USB port is fixed on the rigid inner shell. The USB port passes through the flexible rubber deformation block and can be connected to the power supply through the USB window.

[0009] In summary, the present invention has at least one of the following beneficial technical effects: The design of the inner and outer layers of the wireless charger in this invention allows for better heat dissipation during use due to the opening of the micro fan, ventilation grille, and deformable ventilation mesh.

[0010] When not in use, press the charger back and forth to make the flexible shell become oval. At this time, the flexible shell is stretched from side to side, which stretches the holes in the deformable breathable mesh, causing the holes in the deformable breathable mesh to shrink until they fit together. The breathable grilles also fit together for the same reason. At this time, the flexible shell is sealed, ensuring that a large amount of dust will not enter the inside of the wireless charger due to environmental issues when not in use, thus ensuring the charging safety of the wireless charger.

[0011] Meanwhile, due to the inner and outer layers, the flexible outer shell is made of flexible and malleable plastic material. The internal structure design ensures that when the wireless charger is accidentally dropped, the left soft plastic deformation block side always becomes the landing point due to the influence of the center of gravity. At the same time, the auxiliary deformation rod buffers the impact force when falling, and the impact force is applied to the flexible outer shell, which greatly protects the safety of the internal circuit board and other components.

Detailed Implementation

[0014] The above-mentioned objective of this invention is achieved through the following technical solution: A three-in-one wireless charger, comprising: a flexible outer shell 1 and a rigid inner shell 2, wherein the rigid inner shell 2 is an elliptical cylindrical structure with through slots in the middle and at the top and bottom, a circuit board 3 is fixed inside the rigid inner shell 2, a wireless coil 4 is fixed on the upper layer of the rigid inner shell 2, the wireless coil 4 is connected to the circuit board 3, a sliding groove 201 is also formed on the upper layer of the rigid inner shell 2, a limiting post 202 is provided inside the sliding groove 201, soft rubber deformation blocks 5 are respectively provided on the left and right sides of the rigid inner shell 2, the soft rubber deformation blocks 5 are in contact with the flexible outer shell 1 outward, a push rod 501 is connected inward to the soft rubber deformation blocks 5, a push block 502 is connected to the other end of the push rod 501, a rotating column is provided inside the push block 502, and an auxiliary deformation rod 6 is connected to the rotating column.

[0015] Specifically, the soft rubber deformable block 5 is made of relatively heavy plastic material, and the left soft rubber deformable block 5 is a solid structure, which makes the center of gravity of the wireless charger biased to the left.

[0016] Specifically, the flexible outer shell 1 is made of flexible deformable plastic material. A ventilation window is opened in the middle of the flexible outer shell 1. At the same time, ventilation grilles 102 are provided on the top and bottom of the flexible outer shell 1. A deformable ventilation net 103 is fixedly connected to the ventilation window.

[0017] Specifically, the auxiliary deformation rod 6 includes a connecting rod 601. One end of the connecting rod 601 is rotatably connected around the rotating column. A slide rail groove 603 is provided in the middle of the connecting rod 601. The limiting column 202 can move within the slide rail groove 603. The other end of the connecting rod 601 is connected to a rotating push block 604. The rotating push block 604 can rotate at an angle on the connecting rod 601 and move together with the connecting rod 601.

[0018] Specifically, a USB window 104 is provided on the right side of the flexible outer shell 1, and a micro fan 7 is provided on the left side of the flexible outer shell 1. The micro fan 7 is connected to the circuit board 3. A USB port 8 is fixed on the rigid inner shell 2. The USB port 8 passes through the soft rubber deformation block 5 and can be connected to the power supply through the USB window 104.

[0019] Working principle: When the wireless charger needs to work, pressing the soft rubber deformation blocks 5 at both ends of the wireless charger towards the middle will drive the push rod 501 and push block 502 to move towards the middle. At this time, the auxiliary deformation rod 6 rotates, expanding the short axis of the ellipse of the flexible shell 1 outward, eventually forming a circle. Due to the deformation of the flexible shell 1, the ventilation grilles 102 of the upper and lower layers of the flexible shell 1 open. At the same time, the deformation ventilation net 103 returns to its structure with regular ventilation holes in the middle after the lateral tension is removed. Since the flexible shell 1 changes from an ellipse to a circle, the long axis shortens, and the USB port 8, which was originally located at the long axis, extends outward through the USB window 104, which can be connected to the power source. At this time, the mobile phone is placed on the upper layer of the flexible shell 1, which is in contact with the wireless coil 4 for charging. At the same time, the micro fan 7 dissipates heat, and the hot air is exchanged with the outside air through the ventilation holes on all four sides, which greatly increases the heat dissipation effect and ensures the quality of wireless charging.

[0020] After wireless charging is complete, the auxiliary deformation rods 6 on both sides of the flexible outer shell 1 are compressed. At this time, the auxiliary deformation rods 6 push the push rod 501 to the left and right sides through the rotating column. Driven by the push rod 501, the soft rubber deformation blocks 5 on the left and right sides move to the left and right respectively, causing the outer flexible outer shell 1 to move to the left and right sides. At this time, the flexible outer shell 1 changes from a circle to an ellipse. At the same time, due to the lengthening of the left and right ends, the ventilation grille 102 and the deformation ventilation mesh 103 are both stretched to the left and right. At this time, the ventilation holes in the deformation ventilation mesh 103 are stretched and closed, and the gaps in the ventilation grille 102 are also stretched and fitted. The originally protruding USB port 8 is also retracted into the wireless charger due to the movement of the flexible outer shell 1. At this time, the ventilation holes on the outside of the wireless charger are closed, which can prevent dust from entering the wireless charger and ensure the safety of subsequent use of the wireless charger.

[0021] Due to the weight design of the soft rubber deformation block 5, the center of gravity of the wireless charger is biased towards the end with the soft rubber deformation block 5. When the wireless charger accidentally falls from a height, the end with the soft rubber deformation block 5 will always face the ground. At this time, under the action of the force-bearing surface, the impact force will be buffered to the auxiliary deformation rod 6 and finally eliminated between the auxiliary deformation rod 6 and the flexible outer shell 1. It will not have a significant impact on the internal rigid inner shell. At the same time, since the flexible outer shell of the wireless charger is made of flexible and deformable plastic material, it also greatly buffers the impact force and can effectively protect the wireless charger.

[0022] Therefore, the wireless charger of the present invention has a three-in-one function of heat dissipation, dust prevention and buffering, and has a better performance.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
