Description

Technical Field

[0001] This utility model relates to the field of wireless charging technology, and in particular to a wireless charging structure and vehicle. Background Technology

[0002] The core advantage of wireless charging is its freedom from physical cables, achieving "contactless power supply" through technologies such as electromagnetic induction and magnetic resonance. It significantly outperforms wired charging in terms of convenience, safety, and device protection. In-vehicle wireless charging further adapts to the "mobility, space constraints, and driving safety" needs of the automotive environment, focusing on the pain points of "driving safety, space utilization, and mobile charging" in vehicles, becoming an important feature of vehicle intelligence. Both phones with magnetic rings (Apple MPP) and those without (Android EPP) require in-vehicle wireless charging. However, due to the camera protrusion of Apple phones causing tilt issues, charging stands for Apple phones are typically raised to ensure the magnetic ring adheres tightly and aligns with the coil, improving coupling efficiency and anti-slip properties. For Android phones without magnetic rings and requiring stable placement, charging stands are usually flush with the base, providing a stable support surface and reducing the risk of slippage.

[0003] A raised charging platform can solve the coil misalignment problem caused by the camera tilt of iPhones, ensuring charging efficiency. However, for Android phones, the raised platform causes the phone, lacking a magnetic ring, to be supported only at a single point, resulting in a suspended center of gravity, sliding, shifting, or even falling, interrupting charging or damaging the device. If the charging platform is flush with the base to ensure stability for Android phones, it cannot compensate for the camera tilt of iPhones, leading to magnetic failure, coil misalignment, energy dissipation, a 20% decrease in coupling efficiency, slower charging speed, increased heat generation, and reduced overall efficiency.

[0004] Therefore, there is an urgent need for a wireless charging structure and vehicle to solve the above problems. Utility Model Content

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1-4 As shown, this embodiment provides a wireless charging structure, which includes a charging base 100, a charging platform 200, and an adjustment unit 300. The upper surface of the charging base 100 is provided with a charging plane 110, and the charging plane 110 is provided with a charging hole 111. The charging platform 200 is provided corresponding to the charging hole 111, and the charging platform 200 is provided with at least a first charging position flush with the charging plane 110 and a second charging position protruding from the charging plane 110. A charging coil 210 is provided inside the charging platform 200, and the charging coil 210 is compatible with the MPP charging protocol and the EPP charging protocol. The adjustment unit 300 is provided on the charging base 100, and the charging platform 200 is provided on the adjustment end of the adjustment unit 300. The adjustment unit 300 can drive the charging platform 200 to switch between the first charging position and the second charging position.

[0039] The charging base 100 integrates the charging platform 200 and the adjustment unit 300. The upper surface of the charging base 100 is a charging plane 110 with a charging hole 111. The charging platform 200 charges the device to be charged, and the charging coil 210 of the charging device is compatible with both MPP and EPP charging protocols, meaning it can charge both Apple and Android phones, offering greater versatility. To ensure hardware compatibility with both Apple and Android phones, the charging platform 200 has a first charging position flush with the charging plane 110, enabling charging of Android phones and ensuring greater stability when the Android phone is placed on the charging base 100. The charging platform 200 also has a second charging position protruding from the charging plane 110, enabling charging of Apple phones. This second charging position compensates for the tilt angle caused by the protruding camera of the Apple phone, ensuring a higher fit between the charging platform 200 and the Apple phone, thus making magnetic charging more reliable and efficient. Specifically, the wireless charging device is also equipped with an adjustment unit 300 to enable the charging station 200 to switch between the first charging position and the second charging position.

[0040] Understandably, the MPP charging protocol, or Magnetic Power Profile, is a magnetic wireless charging protocol led by Apple and based on the Qi standard. The EPP charging protocol, or Extended Power Profile, is part of the Qi standard developed by the Wireless Power Consortium (WPC).

[0041] Specifically, the charging platform 200, positioned in the second charging position, protrudes approximately 4.5mm from the charging plane 110. This effectively compensates for the tilt angle caused by the Apple phone's camera, allowing the Apple phone to reliably adhere to the charging platform 200. At this point, the distance between the Apple phone and the charging coil 210 is reduced to less than or equal to 1mm, effectively eliminating the misalignment problem of the charging coil 210. The charging efficiency (coupling efficiency) increases from 65% to 85%+, and the temperature rise decreases by 40%. The magnetic attraction force of the charging platform 200 on the Apple phone is no less than 2N, resulting in almost zero sliding displacement between the Apple phone and the charging platform 200. The charging platform 200, positioned in the first charging position, is flush with the charging plane 110. Figure 1 and Figure 3 As shown, the tolerance of ±0.1mm makes the Android phone more stable when placed on the charging surface 110. Furthermore, the charging platform 200 and the charging surface 110 form a full-area support surface to support the Android phone, resulting in an anti-slip force greater than 1.8N. Under vibration conditions, the charging interruption rate drops from 40% to 0.1%, eliminating the risk of slippage and effectively improving the reliability of charging Android phones.

[0042] Preferably, the wireless charging structure is further provided with a third charging position, wherein the charging platform 200 placed in the third charging position protrudes from the charging plane 110, and the distance of protrusion from the charging plane 110 is greater than the distance of protrusion from the charging platform 200 placed in the second charging position, so as to adapt to Apple mobile phones with tilt angles caused by different camera thicknesses, thereby further improving the versatility of the wireless charging structure.

[0043] This embodiment also discloses a vehicle including the wireless charging structure described in any of the above embodiments. A vehicle equipped with the above wireless charging structure can wirelessly charge both Apple and Android phones inside the vehicle. A single device is compatible with both protocols, reducing the cost of using two devices by half. Charging efficiency is higher for Apple phones, and placement is more stable for Android phones. The switching between the two charging positions is convenient and reliable, improving the vehicle's technological sophistication and the user experience.

[0044] As an alternative solution for wireless charging structure, such as Figure 3 As shown, the charging plane 110 is surrounded by retaining walls 130 to protect the wireless charging structure from drops during driving. This reduces damage to the charging device and prevents a falling device from affecting driving safety. Optionally, the height of the retaining wall 130 in front of the vehicle is greater than the height of the retaining wall 130 behind the vehicle in the direction of travel, reducing the impact of the retaining wall 130 on users when temporarily viewing the charging device. Furthermore, the retaining walls 130 on the left and right sides of the vehicle connect the front and rear retaining walls 130; therefore, the upper ends of the side retaining walls 130 are angled, making the overall wireless charging device more aesthetically pleasing.

[0045] Specifically, the adjustment unit 300 is equipped with an adjustment plate 310 and an adjustment component 320. The charging platform 200 is mounted on the adjustment plate 310. The adjustment component 320 can drive the adjustment plate 310 to rise and fall, allowing the charging platform 200 to switch between a first charging position and a second charging position. The adjustment component 320 is used to switch the charging position of the charging platform 200; the adjustment plate 310 is used to facilitate the transmission between the adjustment component 320 and the charging platform 200. It is understood that the size of the charging platform 200 is limited, and the structure of the adjustment component 320 is relatively complex to achieve the switching of the charging position. Therefore, by setting the adjustment plate 310, more space is provided for the installation of the adjustment component 320, avoiding the limitation that the adjustment component 320 can only be installed as an accessory to the charging platform 200. This increases the design freedom of the adjustment component 320, reduces the degree of processing, and helps to reduce costs.

[0046] Furthermore, two adjustment components 320 are provided, which helps to increase the driving force for moving the charging platform 200. For example, the two adjustment components 320 are provided at both ends of the adjustment plate 310 along the length direction, so that the driving force of the adjustment components 320 on the adjustment plate 310 is more uniform, avoiding the problem of the adjustment plate 310 getting stuck during the lifting and lowering process that is easily caused by only one adjustment component 320, and improving the smoothness and reliability of the charging platform 200 in the charging position conversion process.

[0047] In this embodiment, the adjustment component 320 includes an elastic reset member 321 and mating grooves of different depths arranged sequentially along the circumference. Correspondingly, the charging platform 200 is provided with guide protrusions. When the charging platform 200 is subjected to force, the elastic reset member 321 causes the guide protrusions to tend to abut against the bottom of the mating grooves. Combined with the different depths of the mating grooves, the charging platform 200 has different charging positions when the guide protrusions mate with different mating grooves. Furthermore, when the charging platform 200 is subjected to force again, it can switch between different charging positions. The switching adjustment only requires the user to press the charging platform 200. Specifically, the user presses the charging platform 200 to the first charging position, and when the user presses the charging platform 200 again, the charging platform 200 rises to the second charging position under the drive of the elastic reset member 321, with a "click" sound indicating each adjustment. The adjustment method is simple and quick.

[0048] Optionally, the elastic reset element 321 can be a spring, which is simple in structure and low in cost. Alternatively, the elastic reset element 321 can be a pneumatic damping rod, which adjusts the lifting resistance through a pneumatic chamber, eliminating metal fatigue and extending the service life by approximately three times compared to a spring; specifically, it adopts a structure of a miniature cylinder and piston. Alternatively, the elastic reset element 321 can be a torsion spring, working in conjunction with a lever mechanism. When the user presses the charging platform 200, it synchronously drives the lever to rotate, storing energy in the torsion spring. When the user presses the charging platform 200 again, the torsion spring releases energy to achieve the switching of the charging position, improving the stroke accuracy by approximately ±0.05mm. It is worth noting that those skilled in the art can set the specific form of the elastic reset element 321 according to the actual situation, and no specific limitation is made here.

[0049] In another embodiment, the adjustment assembly 320 includes an adjustment knob and a meshing gear set, wherein one gear in the gear set meshes with the charging platform 200, and the other gear meshes with the adjustment knob. When it is necessary to adjust the charging position of the charging platform 200, the user only needs to turn the adjustment knob, which drives the gear set to rotate and move the charging platform 200. For example, the adjustment knob can be set to protrude from the side of the charging base 100, which does not occupy the charging plane 110 and is convenient for the operator to operate. The advantage of adjusting with the adjustment knob is that it can effectively prevent accidental activation and makes locking more reliable. It is worth noting that the specific configuration and transmission path of the gear set can be set by those skilled in the art according to the actual situation, and are not specifically limited here.

[0050] It is worth noting that the aforementioned adjustment component 320 is set up based on manual operation. That is, when the user needs to adjust the charging position, they need to manually press the charging platform 200 or turn the adjustment knob. The manual adjustment structure is simple, highly reliable, energy-independent, provides instant physical feedback, is intuitive to operate, low in cost, and easy to maintain.

[0051] In another embodiment, the adjustment component 320 can also be adjusted electrically. Optionally, the adjustment component 320 includes an electric push rod, which is disposed on the charging base 100, and the charging platform 200 is disposed on the drive end of the electric push rod. When the electric push rod is energized, it can drive the charging platform 200 to move, thereby changing the charging position. Alternatively, the adjustment component 320 includes a drive motor and a lead screw, with the charging platform 200 threadedly connected to the lead screw. When the drive motor is activated, it can drive the lead screw to rotate, thereby causing the charging platform 200 threadedly connected to the lead screw to rise and fall to change the charging position. The drive motor is a micro motor and is powered via USB. The control method can be switched via buttons or an APP, providing more control options. It is understood that the electric push rod is a linear drive component, which can drive the charging platform 200 to rise and fall to change the charging position. The drive motor is a rotary drive component, which needs to be used in conjunction with a transmission structure to convert the rotary motion into linear motion. In other embodiments, a worm gear structure or a crank-slider structure can also be used, which is not specifically limited here. Electric adjustment offers high precision and consistency; it facilitates automation and remote control, and can be integrated with multiple functions.

[0052] As an optional solution for the wireless charging structure, the charging base 100 has a heat dissipation opening 120 at its bottom, which corresponds to the charging platform 200. It can be understood that the charging base 100 is a hollow shell, with its upper surface extending to form a charging plane 110. Structures such as the adjustment unit 300 are housed inside the shell, which improves the overall integration and aesthetics of the wireless charging structure while providing some protection for the internal structures and components. However, since the charging coil 210 of the charging base 100 generates heat during charging, heat accumulation can affect charging safety. Therefore, the charging base 100 has a corresponding heat dissipation opening 120 at its bottom for heat dissipation of the charging coil 210.

[0053] Specifically, the wireless charging structure also includes a protective plate 400, which is located inside the charging base 100 and below the charging platform 200. The protective plate 400 strengthens the structural integrity of the charging platform 200. Preferably, the protective plate 400 has a corresponding heat dissipation opening 120 with a protruding heat dissipation window 410, which has multiple heat dissipation holes 411. The protruding heat dissipation window 410 avoids interference with the charging platform 200 during the switching of charging positions and provides more space for heat dissipation of the charging platform 200. Furthermore, the heat dissipation window 410 also has heat dissipation holes 411 that communicate with the heat dissipation opening 120, ensuring effective heat dissipation while strengthening the structure.

[0054] In this embodiment, the wireless charging structure also includes a cooling fan 500, which is positioned between the charging platform 200 and the heat dissipation window 410. It is understood that the protruding heat dissipation window 410 provides sufficient space for the cooling fan 500. By placing the cooling fan 500 between the charging platform 200 and the heat dissipation window 410, heat dissipation of the charging platform 200 is accelerated, allowing heat to flow more quickly through the heat dissipation holes 411 of the heat dissipation window 410 to the heat dissipation opening 120, and finally out of the wireless charging structure. This ensures that the charging platform 200 operates at a suitable temperature, improving the reliability and safety of the wireless charging structure.

[0055] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
