Description

Technical Field

[0001] The utility model relates to the technical field of wireless charging interfaces, in particular to a universal wireless charging interface. Background Art

[0002] With the wide use of mobile devices such as smart phones, tablet computers, and smart watches, people's demand for charging is increasing day by day. The universal wireless charging interface can provide charging for devices of different brands and models, greatly improving convenience. In modern society, people pursue a more concise and efficient lifestyle, meeting the needs of modern life. The continuous progress of technology has promoted the development of wireless charging technology, including multiple technical routes such as electromagnetic induction, electromagnetic resonance, and radio waves, enabling the realization and continuous improvement of the universal wireless charging interface.

[0003] In the prior art, wireless charging relies on the close contact between the device and the charger. Although wireless charging technology provides the convenience of not having to plug and unplug, its charging process still depends on maintaining stable contact between the device and the charger. Once the contact is poor, it may affect the effective transmission of energy. If the contact between the data cable or the device and the charger is unstable, it may lead to charging interruption or reduced efficiency. If the interface design of the wireless charger is not firm enough, or there are defects in the connection part between the data cable and the charger, the device is likely to fall off during charging, interrupting the charging process. Summary of the Utility Model

[0004] The purpose of the utility model is to propose a universal wireless charging interface to solve the disadvantages existing in the prior art.

[0005] To achieve the above object, the utility model adopts the following technical solutions: a general-purpose wireless charging interface, including a wireless charging device, the circumferential surface of the wireless charging device is electrically connected with a charging interface, the surface of the wireless charging device is rotatably connected with a rotating ring, a sliding groove is opened inside the rotating ring, a fixed tooth is slidably connected inside the rotating ring, a fixed spring is fixed on the upper end surface of the fixed tooth, the fixed spring is fixedly connected with the rotating ring, a push button is slidably connected inside the rotating ring, and a trapezoidal platform is fixed on the surface of the push button. In the prior art, wireless charging relies on the close contact between the device and the charger. Although wireless charging technology provides the convenience of no need to plug and unplug, its charging process still depends on maintaining a stable contact between the device and the charger. Once the contact is poor, it may affect the effective transmission of energy. If the contact between the data cable or the device and the charger is unstable, it may cause the charging to be interrupted or the efficiency to be reduced. If the interface design of the wireless charger is not firm enough, or there are defects in the connection part between the data cable and the charger, the device is likely to fall off during charging, interrupting the charging process. To solve such problems, the utility model adopts an expansion tooth device. The staff pushes the wireless charging cable forward along the fixed tooth, and the fixed tooth opens reversely by means of its own inclined surface, so as to promote the charging cable to be inserted into the charging interface. At the same time, due to the accumulation of elastic force, the fixed spring presses on the fixed tooth, prompting the fixed tooth to clamp the charging cable. When the staff wants to pull out the charging cable, press the push button to prompt the fixed tooth to be unfolded to both sides by the trapezoidal platform, so as to pull out the charger, thus making the contact between the charger and the wireless charging interface more stable, avoiding falling off caused by external factors, and making the use process more stable.

[0006] Preferably, a spring buckle is fixed on the circumferential surface of the wireless charging device, and a limiting column is fixed on the inner wall of the rotating ring. In the prior art, the wireless charging interface is exposed to the external environment when idle, and it is easy to accumulate dust and fine particles. These impurities may hinder the transmission of the electromagnetic field during the charging process, resulting in a reduction in charging efficiency. Once the dust accumulates, it may be difficult to clean the wireless charging interface, especially if the interface design is relatively closed or difficult to reach, which requires the user to spend extra time and energy for maintenance. Since the dust accumulation may cause poor charging contact, the user may need to frequently replace or adjust the device position, which not only affects the charging efficiency but also may affect the compatibility between devices. To solve such problems, the utility model adopts the installation of a rotating ring. When the wireless charging interface is idle, the staff rotates the rotating disk, so that the limiting column inside the rotating ring compresses the spring buckle to move, and the wireless charging interface is hidden inside the rotating ring, thus avoiding the problem of poor contact caused by dust adsorption inside the wireless charging interface and improving the user experience.

[0007] Preferably, the fixing spring is a double-strand spring. Compared with a single-strand spring, a double-strand spring can bear a greater load. The design of the double-strand spring enables the spring to maintain good elasticity and performance after long-term use, thereby extending the service life of the fixing spring.

[0008] Preferably, a rubber sleeve is sleeved on the surface of the push button, so as to further improve the user's operation experience, make the operation smoother, and thus enhance the user's handling feel.

[0009] Preferably, the charging interface has multiple different models. By providing multiple different models of charging interfaces, the charging needs of different devices and users can be met. No matter which model of device the user uses, they can conveniently find a suitable charging method, thereby expanding the applicable range of the wireless charging interface.

[0010] Preferably, the cross-section of the fixing tooth is triangular. The triangular design has self-locking property, which means that once the charger is fixed in place, it is not easy to loosen or slip off, thus improving the reliability of the fixing tooth.

[0011] Beneficial effects

[0012] 1. In the prior art, wireless charging relies on the close contact between the device and the charger. Although wireless charging technology provides the convenience of not having to plug and unplug, its charging process still depends on maintaining a stable contact between the device and the charger. Once the contact is poor, it may affect the effective transmission of energy. If the contact between the data cable or the device and the charger is unstable, it may cause the charging to be interrupted or the efficiency to be reduced. If the interface design of the wireless charger is not firm enough, or there are defects in the connection part between the data cable and the charger, the device is likely to fall off during charging, interrupting the charging process. To solve such problems, in the present utility model, by adopting the expansion tooth device, the staff pushes the wireless charging cable forward along the fixing tooth. The fixing tooth opens reversely by virtue of its own inclined plane, thereby promoting the charging cable to be inserted into the charging interface. At the same time, due to the accumulation of elastic force, the fixing spring exerts pressure on the fixing tooth, prompting the fixing tooth to clamp the charging cable. When the staff wants to pull out the charging cable, they press the push button, causing the fixing tooth to be expanded to both sides by the trapezoidal platform, thereby pulling out the charger, so as to make the contact between the charger and the wireless charging interface more stable, avoid falling off caused by external factors, and make the use process more stable.

[0013] 2. In the prior art, the wireless charging interface is exposed to the external environment when idle, which is prone to accumulating dust and fine particles. These impurities may hinder the electromagnetic field transmission during charging, resulting in a decrease in charging efficiency. Once dust accumulates, it may be relatively difficult to clean the wireless charging interface, especially if the interface design is relatively enclosed or difficult to reach. This requires users to spend extra time and effort on maintenance. Since dust accumulation may lead to poor charging contact, users may need to frequently replace or adjust the device position, which not only affects the charging efficiency but also may affect the compatibility between devices. To address such problems, the present utility model adopts an installation of a rotating ring. When the wireless charging interface is idle, the staff rotates the rotating disk, causing the limiting column inside the rotating ring to compress the spring buckle and move, so that the wireless charging interface is hidden inside the rotating ring, thereby avoiding the problem of poor contact caused by dust adsorption inside the wireless charging interface and improving the user experience.

[0021] The following describes the specific embodiments of the present utility model with reference to the drawings. Specific Embodiment:

[0023] Refer to Figures 1-4, Universal wireless charging interface, including a wireless charging device 1. A charging interface 101 is electrically connected to the peripheral surface of the wireless charging device 1.

A fixed tooth 203 is slidably connected inside the rotating ring 2. A fixed spring 205 is fixed to the upper end surface of the fixed tooth 203. The fixed spring 205 is fixedly connected to the rotating ring 2. A push button 202 is slidably connected inside the rotating ring 2. A trapezoidal platform 2021 is fixed to the surface of the push button 202. In the prior art, wireless charging relies on the close contact between the device and the charger. Although wireless charging technology provides the convenience of not having to plug and unplug, its charging process still depends on maintaining a stable contact between the device and the charger. Once the contact is poor, it may affect the effective transmission of energy. If the contact between the data cable or the device and the charger is unstable, it may lead to charging interruption or reduced efficiency. If the interface design of the wireless charger is not firm enough, or there are defects in the connection part between the data cable and the charger, the device is likely to fall off during charging, interrupting the charging process. To address such problems, in the present utility model, by adopting an expanding tooth device, the staff pushes the wireless charging cable forward along the fixed tooth 203. The fixed tooth 203 opens in the opposite direction by means of its own inclined surface, thereby promoting the charging cable to be inserted into the charging interface 101. At the same time, due to the accumulation of elastic force, the fixed spring 205 exerts pressure on the fixed tooth 203, prompting the fixed tooth 203 to clamp the charging cable. When the staff wants to unplug the charging cable, they press the push button 202, causing the fixed tooth 203 to be expanded to both sides by the trapezoidal platform 2021, thereby unplugging the charger, so as to make the contact between the charger and the wireless charging interface 101 more stable, avoid falling off caused by external factors, and make the use process more stable.

The fixed spring 205 is a double-strand spring. A rubber sleeve is sleeved on the surface of the push button 202. The charging interface 101 has multiple different models. The cross-section of the fixed tooth 203 is triangular.

[0025] The working principle of the present utility model: When the staff connects the wireless charger to the charging interface 101, the staff pushes the wireless charging cable forward along the fixed tooth 203. The fixed tooth 203 opens in the opposite direction by means of its own inclined surface, thereby promoting the charging cable to be inserted into the charging interface 101. At the same time, due to the accumulation of elastic force, the fixed spring 205 exerts pressure on the fixed tooth 203, prompting the fixed tooth 203 to clamp the charging cable. When the staff wants to unplug the charging cable, they press the push button 202, causing the fixed tooth 203 to be expanded to both sides by the trapezoidal platform 2021, thereby unplugging the charger.
