Description

[0002] Under the general trend of the intelligent development of modern automobiles, in-vehicle wireless chargers, as a convenient in-vehicle electronic device, have been favored by the majority of car owners.

However, there are many problems to be solved urgently in the actual use of traditional in-vehicle wireless chargers widely used in the market at present.

[0003] First of all, the clamping device of the traditional in-vehicle wireless charger performs poorly in fixing the mobile phone. Its structure is usually relatively simple, mostly using basic spring claws or simple snap-fit structures, and it is difficult to provide a stable and reliable fixing effect. During the driving of the vehicle, especially when encountering bumpy roads or situations such as sudden braking or sharp turning, the clamped mobile phone is prone to shaking and even directly falling off the charger. This will not only cause the charging to be interrupted and affect the charging effect, but also may damage the mobile phone due to collision. More seriously, the shaking or falling of the mobile phone will distract the driver's attention, and the driver has to be distracted to deal with the mobile phone during driving, which undoubtedly brings great potential safety hazards to driving.

A vehicle-mounted wireless charger with stable clamping according to this embodiment, a first driving inclined surface 56 is arranged in the middle of the first driving inclined groove 54; a second driving inclined surface 57 is arranged in the middle of the second driving inclined groove 55; the limiting block 4 is telescopically and movably arranged on the top of the base 1; a limiting spring 44 is arranged between the limiting block 4 and the bottom wall of the accommodating cavity 11.A vehicle-mounted wireless charger with stable clamping according to this embodiment, the linkage groove includes a first linkage straight groove 71 arranged along the width direction of the base 1 and a second linkage straight groove 72 arranged along the width direction of the base 1; a first linkage inclined groove 73 is provided between one end of the first linkage straight groove 71 and one end of the second linkage straight groove 72; a second linkage inclined groove 74 is provided between the other end of the first linkage straight groove 71 and the other end of the second linkage straight groove 72; the depth of the first linkage straight 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 straight groove 72 are the same; a limiting pit 75 is provided in the middle of the first linkage straight groove 71; a blocking convex block 76 is provided between the other end of the first linkage straight groove 71 and the second linkage inclined groove 74. A vehicle-mounted wireless charger with stable clamping according to this embodiment, the second linkage inclined groove 74 is provided with a linkage inclined surface 77; a spring piece 8 is provided on the side wall of the accommodating cavity 11; the driving seat 5 abuts against the spring piece 8. A vehicle-mounted wireless charger with stable clamping according to this embodiment, a linkage spring 61 is provided between the round pin 6 and the bottom of the driving seat 5.

[0037] Specifically, for the vehicle-mounted wireless charger with stable clamping according to this embodiment, before the mobile phone is installed, under the action of the spring piece 8, the round pin 6 is located at the other end of the first linkage straight groove 71, and the friction surface abuts against the friction ring 31. At this time, the pin shaft 43 is directly above the first driving straight groove 51;

[0038] When inserting the mobile phone, under the action of the guiding inclined surface 41, the mobile phone drives the limiting block 4 to descend. The pin shaft 43 enters the first driving linear groove 51 and descends along the first driving linear groove 51. When the mobile phone passes over the limiting block 4, the pin shaft 43 falls into the first driving inclined groove 54. Then, under the action of the limiting spring 44, the limiting block 4 needs to move upward, so the pin shaft 43 moves upward along the first driving inclined groove 54. During the process of the pin shaft 43 moving upward along the first driving inclined groove 54, it drives the round pin 6 to move along the first linkage linear groove 71 and starts to compress the elastic piece 8. In addition, during the process of the round pin 6 moving along the first linkage linear groove 71, the driving seat 5 moves synchronously and drives the friction ring 31 to rotate through the friction surface, so that the rotating disc 3 rotates. During the rotation of the rotating disc 3, the spiral spring 32 is compressed. The first guiding block 25 and the second guiding block 26 are respectively driven by the first arc-shaped groove 33 and the second arc-shaped groove 34, so that the first guiding block 25 and the second guiding block 26 move along the first guiding linear groove 23 and the second guiding linear groove 24 respectively, so that the first clamping plate 21 and the second clamping plate 22 approach each other, and the mobile phone is fixed between the first clamping plate 21, the second clamping plate 22, the limiting block 4 and the limiting 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 exits from above the second driving linear groove 52, completing the reset of the limiting block 4. At this time, the elastic piece 8 presses the round pin 6 tightly in the limiting pit 75, and the connection between the first clamping plate 21, the second clamping plate 22, the limiting block 4, the limiting plate 13 and the mobile phone is stable.

[0039] When the mobile phone needs to be taken out, the limiting block 4 is pressed down again, so that the pin shaft 43 enters the second driving linear groove 52. When the pin shaft 43 enters the second driving inclined groove 55, the limiting block 4 is continuously pressed down, so that the pin shaft 43 descends along the second driving inclined groove 55, so that the round pin 6 continues to move along the direction of the first linkage inclined groove 73. Until the pin shaft 43 falls to the bottom of the second driving linear groove 52, the round pin 6 also falls into the first linkage inclined groove 73. Then the limiting block 4 resets and exits from above the third driving linear groove 53. At this time, under the action of the elastic piece 8, the round pin 6 is driven to move along the first linkage inclined groove 73, resulting in the separation of the friction surface and the friction ring 31. Under the action of the spiral spring 32, the rotating disc 3 resets, driving the first clamping plate 21 and the second clamping plate 22 to separate, and at this time the mobile phone can be taken out.

[0040] In addition, under the action of the elastic piece 8, after driving the round pin 6 to move along the first linkage inclined groove 73, the second linkage linear groove 72 and the second linkage inclined groove 74 in sequence, it falls into the other end of the first linkage linear groove 71 again, the friction surface abuts against the friction ring 31 again, and the pin shaft 43 is located directly above the first driving linear groove 51 again.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
