[0002] As modern cars become more intelligent, in-car wireless chargers are becoming increasingly popular among car owners as a convenient in-car electronic device. They free drivers from the constraints of traditional charging cables and allow them to charge their phones more conveniently. However, the traditional in-car wireless chargers currently in widespread use face numerous challenges that need to be addressed.
[0003] First, the clamping mechanism of traditional in-car wireless chargers performs poorly in securing phones. Their structure is typically simple, often employing basic spring-loaded claws or simple snap-fit mechanisms, which struggle to provide stable and reliable securement. During driving, especially on bumpy roads or during sudden braking or sharp turns, the clamped phone can easily wobble or even fall from the charger. This not only interrupts charging and compromises the charging process, but can also cause damage to the phone. Furthermore, a shaking or falling phone distracts the driver, forcing them to focus on their phone while driving, which undoubtedly poses a significant safety hazard. Summary of the Invention

In this embodiment, a stable in-vehicle wireless charger is provided with a first inclined drive surface 56 in the middle of the first inclined drive slot 54; a second inclined drive surface 57 in the middle of the second inclined drive slot 55; a limit block 4 is telescopically disposed at the top of the base 1; and a limit spring 44 is provided between the limit block 4 and the bottom wall of the accommodating cavity 11.The present embodiment describes a stable, clamping vehicle-mounted wireless charger. The linkage groove comprises a first linkage linear groove 71 and a second linkage linear groove 72 arranged along the width of the base 1. A first linkage inclined groove 73 is provided between one end of the first linkage linear groove 71 and one end of the second linkage linear groove 72. A second linkage inclined groove 74 is provided between the other end of the first linkage linear groove 71 and the other end of the second linkage linear groove 72. The depth of the first linkage linear groove 71 is greater than the depth of the first linkage inclined groove 73. The depths of the first linkage inclined groove 73, the second linkage inclined groove 74, and the second linkage linear groove 72 are the same. A limiting recess 75 is provided in the middle of the first linkage linear groove 71. A blocking protrusion 76 is provided between the other end of the first linkage linear groove 71 and the second linkage inclined groove 74. The present embodiment describes a stable, clamping vehicle-mounted wireless charger. The second linkage inclined groove 74 is provided with a linkage inclined surface 77. The sidewalls of the accommodating cavity 11 are provided with a spring clip 8. The drive seat 5 abuts against the spring clip 8. In the embodiment of the present invention, a stable clamping vehicle-mounted wireless charger is provided with a linkage spring 61 between the round pin 6 and the bottom of the driving seat 5 .
[0037] Specifically, in the embodiment of the in-vehicle wireless charger with stable clamping, before the mobile phone is installed, under the action of the spring 8, the round pin 6 is located at the other end of the first linkage linear groove 71, and the friction surface abuts against the friction ring 31. At this time, the pin shaft 43 is located directly above the first driving linear groove 51;
[0038] When the mobile phone is inserted, the mobile phone drives the limit block 4 to descend under the action of the guide inclined surface 41, and the pin shaft 43 enters the first drive linear groove 51 and descends along the first drive linear groove 51. When the mobile phone passes the limit block 4, the pin shaft 43 falls into the first drive inclined groove 54, and then under the action of the limit spring 44, the limit block 4 needs to move upward, so the pin shaft 43 moves upward along the first drive inclined groove 54. In the process of the pin shaft 43 moving upward along the first drive inclined groove 54, the round pin 6 is driven to move along the first linkage linear groove 71 and begins to compress the spring piece 8. In addition, in the process of the round pin 6 moving along the first linkage linear groove 71, the drive seat 5 moves synchronously and drives the friction ring 31 to rotate through the friction surface, thereby rotating the rotating disk 3. During the movement, the coil spring 32 is compressed, and the first guide block 25 and the second guide block 26 are driven by the first arc groove 33 and the second arc groove 34 respectively, so that the first guide block 25 and the second guide block 26 move along the first guide linear groove 23 and the second guide linear groove 24 respectively, so that the first clamping plate 21 and the second clamping plate 22 are close to each other, thereby fixing the mobile phone between the first clamping plate 21, the second clamping plate 22, the limit block 4 and the limit plate 13; until the round pin 6 moves to the position of the limiting pit 75, the pin shaft 43 falls into the second driving linear groove 52 and withdraws from the top of the second driving linear groove 52, completing the resetting of the limit block 4, at this time the spring piece 8 presses the round pin 6 against the limiting pit 75, and the connection between the first clamping plate 21, the second clamping plate 22, the limit block 4, the limit plate 13 and the mobile phone is firm.
[0039] When the mobile phone needs to be taken out, the limit block 4 is pressed down again to make the pin shaft 43 enter the second drive linear groove 52. When the pin shaft 43 enters the second drive inclined groove 55, the limit block 4 is continued to be pressed down to make the pin shaft 43 descend along the second drive inclined groove 55, so that the round pin 6 continues to move in the direction of the first linkage inclined groove 73 until the pin shaft 43 falls to the bottom of the second drive linear groove 52, and the round pin 6 also falls into the first linkage inclined groove 73. Then the limit block 4 is reset and exits from the top of the third drive linear groove 53. At this time, under the action of the spring 8, the round pin 6 is driven to move along the first linkage inclined groove 73, causing the friction surface to separate from the friction ring 31. Under the action of the coil spring 32, the rotating disk 3 is reset, driving the first splint 21 to separate from the second splint 22. At this time, the mobile phone can be taken out.
[0040] In addition, under the action of the spring piece 8, the round pin 6 is driven to move along the first linkage inclined groove 73, the second linkage linear groove 72 and the second linkage inclined groove 74 in sequence, and then falls back into the other end of the first linkage linear groove 71, and the friction surface is again against the friction ring 31, and the pin shaft 43 is again located directly above the first drive linear groove 51.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
