Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0054] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0055] See Figure 1 and Figure 2 This embodiment provides a vehicle-mounted wireless charging bracket that can hold and charge a mobile phone, and can adjust the angle of the phone in all directions to adapt to the best viewing angle for users of different heights.

[0056] Specifically, in this embodiment, the vehicle-mounted wireless charging bracket includes a wireless charging unit 1, a vehicle body connecting unit 2, and an elastic clamping ring 3.

[0057] The wireless charging unit 1 is used to hold and charge a mobile phone, and the wireless charging unit 1 is provided with a universal ball head receiving part 11.

[0058] One end of the vehicle body connecting part 2 is used to connect to the vehicle, and the other end is provided with a universal ball joint 21, which is rotatably connected to the universal ball joint receiving part 11.

[0059] The elastic clamping ring 3 is elastically fitted onto the outer side of the universal ball joint receiving portion 11 to fix the wireless charging unit 1 at a set viewing angle. An elastic clamping ring mounting guide structure 111 is provided at the end of the universal ball joint receiving portion 11 away from the wireless charging unit 1. The elastic clamping ring mounting guide structure 111 facilitates the quick fitting of the elastic clamping ring 3 onto the outer side of the universal ball joint receiving portion 11.

[0060] In this embodiment, the in-vehicle wireless charging bracket is used by connecting one end of the vehicle body connection part 2 to the vehicle. Since the universal ball joint 21 of the vehicle body connection part 2 is rotatably connected to the universal ball joint receiving part 11, the user can rotate the wireless charging part 1 relative to the vehicle body connection part 2 to a position that best suits their viewing angle. The elastic clamping ring 3 is elastically fitted onto the outer side of the universal ball joint receiving part 11, ensuring that it does not obstruct the user's rotation adjustment of the wireless charging part 1. Once the user has rotated the wireless charging part 1 to the optimal viewing angle, the elastic clamping ring 3 will prevent further rotation, at which point the user can simply clamp their phone onto the wireless charging part 1.

[0061] That is, the elastic clamping ring 3 is elastically sleeved on the outer side of the universal ball head receiving part 11, which will not interfere with the user's adjustment of the phone angle, and can ensure that the phone angle remains stable after it is adjusted to the correct position.

[0062] Specifically, see Figures 1-3 The wireless charging unit 1 includes a wireless charging unit body 12 and a mobile phone clamping unit 13.

[0063] The mobile phone clamping part 13 is disposed on the wireless charging part body 12, and includes a first clamping part 131 and a second clamping part 132 that can move closer to or further away from each other to satisfy the clamping of the mobile phone.

[0064] Specifically, the wireless charging unit body 12 is provided with a wireless charging ring, which is used to wirelessly charge the mobile phone.

[0065] Furthermore, the wireless charging unit 1 has a built-in NFC sensor area, compatible with Huawei HarmonyOS. Users simply need to place their mobile devices that support Huawei HarmonyOS or EMUI 11.0 systems close to the NFC sensor area of ​​the wireless charging unit 1 to instantly detect whether the device is being networked for the first time and complete the connection in seconds. This enables interaction between the phone and third-party devices. It also supports NFC-enabled Android phones and iPhones with iOS 13.0 and above. Passengers in the vehicle can connect to the network to assist the driver with navigation, music playback, and other tasks, freeing the driver's hands and making driving safer.

[0066] In a further preferred embodiment, the vehicle-mounted wireless charging bracket also has NB-IoT (Narrow Band Internet of Things) functionality. A 4G mobile phone clipped onto the vehicle-mounted wireless charging bracket can connect to a cloud server via NB-IoT. The cloud server and the 4G mobile phone are interconnected in the cloud, and the user can achieve voice control and management through offline voice commands.

[0067] NB-IoT is built on cellular networks and consumes only about 180kHz of bandwidth. It can be directly deployed on GSM, UMTS, or LTE networks, reducing deployment costs and enabling smooth upgrades.

[0068] Furthermore, the 4G phone has a cloud-based user app, allowing users to issue commands to the 4G phone and remotely manage it.

[0069] Furthermore, a bottom support plate 121 is also provided on the wireless charging unit body 12. When the mobile phone is placed on the wireless charging unit body 12, the bottom support plate 121 is used to support the bottom of the mobile phone, and the first clamping part 131 and the second clamping part 132 are respectively clamped to the two sides of the mobile phone.

[0070] Specifically, see Figure 3 and Figure 4 In this embodiment, the universal ball head receiving part 11 includes an end plate 112 and a plurality of arc-shaped flaps 113.

[0071] The end plate 112 is fixedly connected to the wireless charging unit 1.

[0072] One end of each arc-shaped valve 113 is fixedly connected to the end plate 112. Several arc-shaped valves 113 are arranged in a circle, and there is a movable gap 1131 between two adjacent arc-shaped valves 113.

[0073] Several arc-shaped petals 113 are arranged in a circle to form a receiving space for the universal ball head 21, and the movable gap 1131 can accommodate the universal rotation of the universal ball head 21.

[0074] Each arc-shaped valve body 113 has an elastic clamping ring installed with a guide structure 111 at its free end.

[0075] Specifically, in this embodiment, the elastic clamping ring mounting guide structure 111 is a guide arc surface, which facilitates the quick fitting of the elastic clamping ring 3 onto the outer side of the universal ball head receiving part 11.

[0076] Furthermore, the arc-shaped petal 113 is an integrally formed structure, including a first arc-shaped portion 1132 and a second arc-shaped portion 1133.

[0077] One end of the first arc-shaped portion 1132 is fixedly connected to the end plate 112.

[0078] One end of the second arc-shaped portion 1133 is fixedly connected to the other end of the first arc-shaped portion 1132. The other end of the second arc-shaped portion 1133 is provided with an elastic clamping ring mounting guide structure 111. The thickness of the second arc-shaped portion 1133 is less than the thickness of the first arc-shaped portion 1132 so that the outer surface of the arc-shaped petal 113 forms a stepped structure.

[0079] The stepped structure facilitates the quick fitting of the elastic clamping ring 3 onto the universal ball joint receiving part 11, and also allows for a certain deformation allowance between the elastic clamping ring 3 and the second arc-shaped part 1133, enabling the universal ball joint 21 to rotate in all directions. The smaller deformation allowance between the first arc-shaped part 1132 and the elastic clamping ring 3 ensures that when the user rotates the wireless charging unit 1 to the optimal viewing angle, the elastic clamping ring 3 stably clamps the universal ball joint receiving part 11, preventing further rotation of the wireless charging unit 1.

[0080] Further, see Figure 5 In this embodiment, the elastic clamping ring 3 is made of elastic material and is ring-shaped. In order to ensure the structural strength of the elastic clamping ring 3, in this embodiment, a plurality of reinforcing protrusions 31 are provided at intervals on the outer surface of the elastic clamping ring 3 along the outer circumferential direction.

[0081] Further, see Figure 6 and Figure 7 In this embodiment, the mobile phone clamping part 13 includes a first clamping part 131 and a second clamping part 132 that can move closer to or further away from each other.

[0082] The first clamping part 131 includes a first clamping plate 1311 and a first connecting part 1312 connected to the first clamping plate 1311 at an angle. The first connecting part 1312 moves through the wireless charging part body 12, and a second receiving cavity with an opening at one end is provided in the first connecting part 1312.

[0083] Specifically, in this embodiment, the first clamping plate 1311 and the first connecting part 1312 are arranged perpendicular to each other.

[0084] The second clamping part 132 includes a second clamping plate 1321 and a second connecting part 1322 connected to the second clamping plate 1321 at an angle. The second connecting part 1322 is slidably sleeved in the second receiving cavity. The second clamping plate 1321 and the first clamping plate 1311 can move closer to each other or further away from each other.

[0085] Specifically, the second clamping plate 1321 and the second connecting part 1322 are arranged perpendicular to each other.

[0086] Furthermore, a second elastic element 133 is connected between the second clamping plate 1321 and the first clamping plate 1311.

[0087] When the user inserts the phone between the second clamping plate 1321 and the first clamping plate 1311, the second clamping plate 1321 and the first clamping plate 1311 move away from each other. The second elastic element 133 is stretched and accumulates elastic potential energy, clamping the phone tightly between the second clamping plate 1321 and the first clamping plate 1311. When the user removes the phone, the second clamping plate 1321 and the first clamping plate 1311 return to their original positions under the elastic restoring force of the second elastic element 133.

[0088] Preferably, two second elastic members 133 are connected between the second clamping plate 1321 and the first clamping plate 1311 to ensure the stability of the mobile phone clamping. The first clamping part 131 also includes a second elastic member receiving part 1313, and the second elastic member receiving part 1313 and the second elastic member 133 are arranged in a one-to-one correspondence. The second elastic member receiving part 1313 is arranged perpendicularly to the first clamping plate 1311, and a second receiving cavity with an opening at one end is provided in the second elastic member receiving part 1313. One end of the second elastic member 133 is fixedly connected to the second clamping plate 1321, and the other end extends into the second receiving cavity and is fixedly connected to the second elastic member receiving part 1313.

[0089] Optionally, in other embodiments, the second clamping plate 1321 and the first clamping plate 1311 can automatically move closer or further apart. For example, the second clamping plate 1321 and the first clamping plate 1311 can automatically move closer or further apart via a lead screw and nut assembly. An infrared sensor switch is provided on the wireless charging unit body 12. After the infrared sensor switch senses the proximity of a mobile phone, it can automatically open and close the second clamping plate 1321 and the first clamping plate 1311. Alternatively, a touch switch can be provided to control the automatic movement of the second clamping plate 1321 and the first clamping plate 1311.

[0090] Further, see Figures 8-10 In this embodiment, the vehicle body connection part 2 includes a vehicle body connection main structure 22 and a connection shaft 23.

[0091] A vehicle body clamping mechanism 221 is provided on the main body connecting structure 22. The vehicle body clamping mechanism 221 is used to clamp the vehicle body structure in the driver's cab.

[0092] One end of the connecting shaft 23 is connected to the main body structure 22 of the vehicle body, and the universal ball joint 21 is located at the other end of the connecting shaft 23.

[0093] Specifically, the vehicle body clamping mechanism 221 includes a first clamp 2211 and a second clamp 2212.

[0094] One end of the first clamp 2211 is fixedly connected to the main body structure 22 of the vehicle body.

[0095] One end of the second clamp 2212 is hinged to the vehicle body connecting main structure 22 and elastically connected to the first clamp 2211, while the other end can open relative to the other end of the first clamp 2211 to clamp onto the vehicle.

[0096] Furthermore, the second clamp 2212 includes a clamp portion 22121 and a hinge portion 22122.

[0097] The clamping part 22121 is disposed opposite to the first clamping part 2211 and can open or close relative to the first clamping part 2211.

[0098] The hinge portion 22122 and the clamping mouth portion 22121 are arranged at an angle. The hinge portion 22122 is hinged to the vehicle body connecting main structure 22. A first receiving cavity with an opening at one end is provided in the hinge portion 22122. A first elastic member 2213 is provided in the first receiving cavity. One end of the first elastic member 2213 is connected to or abuts against the first clamping mouth 2211, and the other end of the first elastic member 2213 abuts against or is connected to the top wall of the first receiving cavity.

[0099] Furthermore, one end of the hinge portion 22122 is perpendicular to the clamp portion 22121, and the other end of the hinge portion 22122 is perpendicularly provided with a pressing portion 22123, the pressing portion 22123 extending in the opposite direction to the clamp portion 22121.

[0100] When the user presses the pressing part 22123, the clamping part 22121 opens relative to the first clamping part 2211, and the first elastic element 2213 is compressed and deformed. After the vehicle body clamping mechanism 221 clamps onto the vehicle structure, the pressing part 22123 is released, and the clamping part 22121 and the first clamping part 2211 close and clamp onto the vehicle structure.

[0101] Preferably, the surface of the first clamping mouth 2211 facing the clamping mouth portion 22121 is provided with a first serrated structure, and the surface of the clamping mouth portion 22121 facing the first clamping mouth 2211 is provided with a second serrated structure to ensure the stability of the vehicle body clamping mechanism 221.
