[0029] As described in the background art, during the process of wireless charging of a mobile phone, it is necessary to take stabilizing measures for the mobile phone to avoid external forces such as sudden braking or aggressive driving during driving, which may affect the charging effect of the wireless charging bracket on the mobile phone.

[0032] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0033] Embodiment 1:

[0034] Please refer to Figure 1-Figure 4 A vehicle-mounted wireless charging bracket comprises a placement box 1, a mounting groove is provided on one side of the placement box 1, and a wireless charging disk 2 is fixedly connected to the inner side of the mounting groove, a first connecting seat 3 is fixedly connected to the side of the placement box 1 away from the wireless charging disk 2, a support frame 4 is provided on the side of the first connecting seat 3 away from the placement box 1, a first connecting ball 5 is fixedly connected to the side of the support frame 4 close to the first connecting seat 3, and the first connecting ball 5 and the first connecting seat 3 are plug-in arranged, a splint 6 is installed on the side of the support frame 4 away from the first connecting ball 5, a stable placement component 7 is installed on the inner side of the placement box 1, a rotation protection component 8 is installed on the top of the support frame 4, and the rotation protection component 8 is used to stabilize the flipping angle of the placement box 1.

[0035] When in use, the whole can be fixed by setting the clamping plate 6, and then the collected items are placed inside the stable placement component 7, and then the mobile phone is wirelessly charged with the wireless charging tray 2. The stable placement component 7 can be set to stably place the mobile phone, thereby reducing the impact on the charging effect caused by the looseness of the mobile phone during the charging process;

[0036] During the process of placing the mobile phone, the placement box 1 can be turned over to change the angle of the placement box 1, so that the placement box 1 is adjusted to a comfortable angle for the driver. At this time, the first connecting ball 5 will rotate inside the first connecting seat 3 and play a role in fixing the angle.

[0037] During the flipping process of the placement box 1, the connection of the rotating protection component 8 can further improve the stability of the placement box 1 after the flipping angle, and at the same time, it can protect the support frame 4 and the first connecting seat 3, thereby improving the service life of the first connecting seat 3 and the support frame 4.

[0038] Embodiment 2:

[0039] This embodiment 2 is used to further disclose the specific structure of the stable placement component 7 based on the above embodiment. Through the coordination of the stable placement component 7 and the structure in the above embodiment, the mobile phone can be placed more stably, so that when the mobile phone is subjected to external force, it can also maintain the charging state, thereby improving the charging effect of the wireless charging of the mobile phone.

[0040] The vehicle-mounted wireless charging bracket provided in Example 1 is further optimized. Specifically, Figure 3-Figure 6 As shown, the stable placement component 7 includes a magnet 9, a fixed shaft 10, a coil spring 11, a rotating ring 12 and a traction rope 13. The four corner positions of the placement box 1 close to the wireless charging disk 2 are fixedly connected to the magnets 9. The inner side of the placement box 1 away from the wireless charging disk 2 is provided with a reserved groove, the middle part of the inner side of the reserved groove is fixedly connected to the fixed shaft 10, the outer side of the fixed shaft 10 is fixedly connected to the coil spring 11, the outer side of the coil spring 11 is fixedly connected to the rotating ring 12, and the outer side of the rotating ring 12 is fixedly connected to the traction rope 13.

[0041] The stable placement component 7 also includes a driving plate 14, a rotating seat 15, a supporting hook 16 and a vertical spring 17. A driving plate 14 is arranged at the bottom of the traction rope 13. The rotating seat 15 is fixedly connected to the center position of the top of the driving plate 14, and the rotating seat 15 and the bottom of the traction rope 13 are rotatably connected. The bottoms of both ends of the driving plate 14 are fixedly connected with supporting hooks 16. The two supporting hooks 16 both penetrate the bottom of the placement box 1 and extend to the outside of the bottom of the placement box 1, and the two supporting hooks 16 are slidably connected to the bottom of the placement box 1. Vertical springs 17 are fixedly connected to both ends of the bottom of the driving plate 14, and the two vertical springs 17 are located between the two supporting hooks 16. The bottoms of the two vertical springs 17 are fixedly connected to the bottom of the inner side of the reserved groove.

[0042] The stable placement component 7 also includes a gear 18, a wrapping plate 19 and a rack 20. The fixed shaft 10 is rotatably connected to the gear 18 on the side away from the wireless charging disk 2. The rotating ring 12 is fixedly connected to the gear 18 on the side away from the wireless charging disk 2. Wrapping plates 19 are provided at both ends of the placement box 1. The two wrapping plates 19 are symmetrically arranged and fixedly connected to the racks 20 on adjacent sides. The two racks 20 are slidably connected to the two ends of the placement box 1 and are respectively located at the top and bottom of the gear 18, and the gear 18 and the two racks 20 are meshing.

[0043] Specifically: when the collection is placed outside the placement box 1, the bottom of the mobile phone will contact the two supporting hooks 16, and then the weight of the mobile phone will drive the two supporting hooks 16 to move downward. In the process of the two supporting hooks 16 moving downward, the driving plate 14 will be driven to move downward synchronously. The driving plate 14 can squeeze the two vertical springs 17 downward, causing the two vertical springs 17 to produce elastic deformation, and the driving plate 14 can be continuously pushed up to drive the two supporting hooks 16 to support the bottom of the mobile phone;

[0044] When the two supporting hooks 16 drive the driving plate 14 to descend, the bottom of the traction rope 13 will be driven to descend synchronously through the setting of the rotating seat 15. At this time, the traction rope 13 will pull the rotating ring 12 to rotate around the fixed shaft 10 as the center, so as to adjust the length of the traction rope 13. When the rotating ring 12 rotates, it will drive the coil spring 11 to rotate synchronously, and at this time, the coil spring 11 will be elastically deformed.

[0045] When the rotating ring 12 rotates, the fixedly connected gear 18 is driven to rotate synchronously outside the fixed shaft 10, and at this time, the two racks 20 meshing with the top and bottom of the gear 18 can be driven to rotate synchronously in opposite directions, thereby driving the two wrapping plates 19 to approach the placement box 1 and wrap and clamp the two ends of the mobile phone, thereby stabilizing the mobile phone. Subsequently, the magnetic force setting of the magnet 9 can further enhance the stabilization effect of the mobile phone.

[0046] When taking the mobile phone away, it is only necessary to lift the mobile phone to cancel the downward pulling force of the mobile phone on the supporting hook 16. At this time, the two supporting hooks 16 will slide upward through the action of the two vertical springs 17 squeezing the driving plate 14, and at the same time, the winding spring 11 will also drive the rotating ring 12 to reversely wind, so that the rotating ring 12 can wind and tighten the traction rope 13, so that the rotating ring 12 can drive the gear 18 to rotate in the opposite direction, and drive the two racks 20 to synchronously move in the opposite direction, so that the two wrapping plates 19 are away from the mobile phone and the wrapping clamping effect on the mobile phone is cancelled;

[0047] By stabilizing the mobile phone, the phenomenon of loosening and falling off when the mobile phone is subjected to external force can be reduced, thereby maintaining a stable charging state and improving the effect of wireless charging of the mobile phone.

[0048] Embodiment 3:

[0049] This embodiment 3 is used to further disclose the specific structure of the rotation protection component 8 on the premise of the above embodiment. By coordinating the rotation protection component 8 with the structure in the above embodiment, the fixing effect of the flip angle can be further enhanced when the mobile phone is flipped on the bracket, and the phenomenon of damage to the flip position after long-term use can be reduced, thereby improving the service life of the wireless charging bracket.

[0050] The vehicle-mounted wireless charging bracket provided in Example 1 and Example 2 is further optimized. Specifically, Figure 7-Figure 8 As shown, the rotation protection component 8 includes a fixed plate 21, a friction strip 22, a sliding block 23 and a friction plate 24. The fixed plate 21 is fixedly connected to the top of the support frame 4. A first sliding groove is opened on the inner side of the fixed plate 21. Second sliding grooves are opened at both ends of the bottom inner side of the first sliding groove. Friction strips 22 are fixedly connected to the inner sides of the two second sliding grooves. A sliding block 23 is slidably connected to the inner side of the first sliding groove. Friction plates 24 are fixedly connected to both ends of the bottom of the sliding block 23. The two friction plates 24 are extruded and frictionally matched with the two fixed plates 21.

[0051] The rotation protection assembly 8 also includes a connecting rod 25, a second connecting ball 26 and a second connecting seat 27. The top of the sliding block 23 is rotatably connected to the connecting rod 25, the top of the connecting rod 25 is fixedly connected to the second connecting ball 26, and the side of the placement box 1 close to the second connecting ball 26 is fixedly connected to the second connecting seat 27, and the second connecting ball 26 and the second connecting seat 27 are plug-in settings.

[0052] Specifically: when adjusting the placement box 1 to flip, the placement box 1 will drive the second connection seat 27 to move synchronously, and at this time the second connection seat 27 will drive the second connection ball 26 to move in the direction close to the support frame 4. Through the spherical setting of the second connection ball 26, it can follow the rotation angle between the first connection ball 5 and the first connection seat 3 to rotate synchronously, thereby reducing the impact on the flipping of the placement box 1;

[0053] When the second connecting ball 26 moves, the sliding block 23 will be driven to slide inside the first sliding groove through the connection setting of the connecting rod 25. During the sliding process of the sliding block 23, the friction plates 24 at both ends of the bottom of the sliding block 23 will slide synchronously inside the second sliding groove, and at the same time, squeeze and rub with the two friction strips 22 inside the second sliding groove. Through the friction setting between the friction strips 22 and the friction plates 24, the movement of the sliding block 23 inside the first sliding groove is damped and limited. The flipping angle of the placement box 1 can be further fixed, thereby protecting the rotational connection between the first connecting ball 5 and the first connecting seat 3. While improving the fixing effect of the flipping angle of the placement box 1, it can also reduce the phenomenon of damage between the first connecting ball 5 and the first connecting seat 3 after long-term use, thereby improving the service life of the wireless charging bracket.
