[0027] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0028] Embodiment 1

[0029] Refer to Figure 1 , 3, 5, is the first embodiment of the present invention, which provides an automatically fixed in-vehicle wireless charger, including: a wireless charger housing 1 and a fixing structure 2. The fixing structure 2 is arranged inside the wireless charger housing 1. The fixing structure 2 includes: a rectangular loading plate 3, which is fixedly connected to the wireless charger housing 1. There are rectangular chutes arranged on the upper surface of a pair of rectangular loading plates 3, and a cylindrical tube 4 is arranged through the inside of the rectangular chute. A layer of rubber strip is arranged on the outer arc surface of the cylindrical tube 4. The cylindrical tube 4 is in a sliding relationship with the rectangular chute. A rectangular sleeve 5 is arranged on the rod body of the cylindrical tube 4 and is penetrated. A memory spring 6 is also arranged on the lower surface of the rectangular sleeve 5. The lower end of the memory spring 6 is connected to the bottom surface of the rectangular chute. A pair of T-shaped moving blocks 7 are arranged on the bottom surface inside the rectangular groove. A ball is also arranged at the bottom of the T-shaped moving block 7. A rope 8 is connected to the vertical surface of the T-shaped moving block 7. One end of the rope 8 and the T-shaped moving block 7 are connected to the rectangular sleeve 5. A cylindrical guide rod is arranged between the long vertical surfaces inside the rectangular groove. The thrust of the memory spring 6 is greater than the tension of the tension spring 12.

[0030] Arc-shaped connecting rods 9 are arranged on the upper surfaces of the T-shaped moving blocks 7. The end points of the arc-shaped connecting rods 9 far away from the T-shaped moving blocks 7 are connected to L-shaped fixing rods 10. The L-shaped fixing rods 10 penetrate through the wireless charger housing 1. A rectangular mounting plate 11 is fixedly connected to the bottom surface inside the rectangular groove. Tension springs 12 are arranged on the vertical surfaces of the rectangular mounting plate 11. The end points of a pair of tension springs 12 far away from the rectangular mounting plate 11 are both connected to the T-shaped moving blocks 7. The T-shaped moving blocks 7 and the tension springs 12 are fixedly connected. A rectangular placement plate 30 is arranged between the opposite vertical surfaces of a pair of rectangular sleeves 5, and the other pair of rectangular sleeves 5 are connected to the same placement frame 33.

[0031] During use, first align the head of the mobile phone with the placement frame 33, and then place the mobile phone into the placement frame 33. At this time, due to the weight of the mobile phone, several rectangular sleeves 5 will descend. Since the rod of the cylinder 4 is provided with rectangular sleeves 5 that are penetrated, and there is a sliding relationship between the rectangular sleeve 5 and the cylinder 4, and a layer of rubber strip is provided on the outer arc surface of the cylinder 4. Because the rubber strip will increase the friction between the rectangular sleeve 5 and the cylinder 4, the rectangular sleeve 5 will descend slowly. Because before descending, the thrust of the memory spring 6 is greater than the tension of the tension spring 12, so when the rectangular sleeve 5 gradually descends, because the vertical surface of the T-shaped moving block 7 is connected to the rope 8, one end of the rope 8 and the T-shaped moving block 7 is connected to the rectangular sleeve 5, and the T-shaped moving block 7 and the tension spring 12 are fixedly connected, and the bottom surface inside the rectangular groove is fixedly connected to the rectangular mounting plate 11. Therefore, during the continuous descent of the rectangular sleeve 5, the tension spring 12 will gradually retract, thereby driving the T-shaped moving block 7 to move. Because arc-shaped connecting rods 9 are provided on the upper surface of the T-shaped moving block 7, and the end of the arc-shaped connecting rod 9 far from the T-shaped moving block 7 is connected to the L-shaped fixing rod 10, and the L-shaped fixing rod 10 penetrates through the wireless charging housing 1, finally the mobile phone will be clamped by several L-shaped fixing rods 10, so as to achieve temporary fixation and charge the mobile phone. Note: Because a layer of rubber strip is provided on the outer arc surface of the cylinder 4, the rubber strip will increase the friction between the rectangular sleeve 5 and the cylinder 4. Therefore, even if the vehicle brakes suddenly, due to the existence of the rubber strip, the rectangular sleeve 5 will not be separated from the wireless charging housing 1, ensuring good fixation.

[0032] Embodiment 2

[0033] Referring to Figure 1-4 , this is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that rectangular connection blocks are provided on one of the vertical surfaces of the rectangular loading plate 3. The rectangular connection blocks and the rectangular loading plate 3 are fixedly connected. And the vertical surface of the rectangular connection block far from the T-shaped moving block 7 is fixedly connected to a circular ring sleeve 13. A fixing ring is provided inside the circular ring sleeve 13, and a rubber airbag 14 is provided at the inner ring of the fixing ring. The gas inside the rubber airbag 14 is nitrogen. Nitrogen is a colorless and odorless gas and is stable under normal temperature and pressure. When the temperature rises between 70 degrees and 80 degrees, the kinetic energy of nitrogen molecules increases, and the repulsive force between molecules increases, causing nitrogen to expand.

[0034] Arc surfaces at both ends of the rubber airbag 14 are fixedly connected with semi-circular sleeves 15. The material of the semi-circular sleeves 15 is hard and cannot be extended. The diameter of the semi-circular sleeves 15 is the same as the inner diameter of the ring sleeves 13. Moreover, mounting openings are provided on the arc surfaces of the semi-circular sleeves 15. An arc-shaped guide rod 16 is provided at the mounting opening on the upper side. And a T-shaped moving block 7 is fixedly connected to the end of the arc-shaped guide rod 16 away from the rubber airbag 14. An L-shaped connecting rod 17 is provided at the mounting opening on the lower side. And the end of the L-shaped connecting rod 17 away from the rubber airbag 14 is connected to a toothed plate 18. And the teeth on the toothed plate 18 are in a meshing relationship with the teeth of the gear column 22. A T-shaped moving groove 19 is provided at the intersection of the toothed plate 18 and the rectangular loading plate 3. And rectangular notches are provided at the intersections of the arc-shaped guide rod 16 and the ring sleeves 13.

[0035] An L-shaped limiting plate 20 is further provided on the lower surface of the rectangular loading plate 3. A threaded rod 21 is provided inside the inner ring of the cylindrical barrel 4. And the threaded rod 21 penetrates through the L-shaped limiting plate 20. The threaded rod 21 and the L-shaped limiting plate 20 are in a rotational relationship. And a gear column 22 is fixedly connected to the rod body of the threaded rod 21. Moreover, a threaded groove is provided on the arc surface inside the rectangular barrel 4. And the threaded groove is in a meshing relationship with the thread on the rod body of the threaded rod 21.

[0036] When in use, first follow the operating steps in Example 1. As the wireless charger continues to charge, the temperature inside the wireless charger frame 1 continues to rise. When the temperature rises to 70 degrees, the nitrogen inside the rubber airbag 14 will expand. Because of the presence of the annular sleeve 13, the rubber airbag 14 will only extend in the direction of both ends. As a pair of semicircular sleeves 15 continue to move, and the arc surface of the semicircular sleeve 15 is also provided with a mounting port, an arc guide rod 16 is provided at the upper mounting port, and the arc guide rod 16 is fixedly connected to the T-shaped moving block 7 at the end away from the rubber airbag 14, and an L-shaped connecting rod 17 is provided at the lower mounting port, and the L-shaped connecting rod 17 is connected to the toothed plate 18 at the end away from the rubber airbag 14, and the teeth on the toothed plate 18 and the teeth of the gear column 22 are in a mutually meshing relationship. When the rubber airbag 14 continues to expand, the arc guide rod 16 will push the T-shaped moving block 7 to move in the direction of the memory spring 6. During the movement, because there is a sliding relationship between the toothed plate 18 and the rectangular loading plate 3, and the teeth on the toothed plate 18 are in meshing relationship with the teeth of the gear column 22, when the toothed plate 18 moves, the toothed plate 18 will rotate with the gear column 22. Because a threaded rod 21 is provided at the inner ring of the cylindrical tube 4, and the rod body of the threaded rod 21 is fixedly connected to the gear column 22, and a threaded groove is provided on the arc surface inside the rectangular tube 4, the threaded groove and the thread on the rod body of the threaded rod 21 are in meshing relationship with each other, at this time, the top surface inside the rectangular sleeve 5 is connected to the cross-section of the top end of the cylindrical tube 4, so when the threaded rod rotates, the cylindrical tube 4 will rise, thereby pushing the rectangular sleeve 5 upward, and finally making the mobile phone detach from the wireless charging frame 1, and blocking the charging of the mobile phone.

[0037] Example 3

[0038] Reference Figure 1 , 2 4 is a second embodiment of the present invention, which is different from the first embodiment in that an L-shaped limit plate 20 is further provided at the lower surface of the rectangular loading plate 3, a threaded rod 21 is provided at the inner ring of the cylindrical tube 4, and the threaded rod 21 penetrates the L-shaped limit plate 20, the threaded rod 21 and the L-shaped limit plate 20 are in a rotational relationship, and a gear column 22 is fixedly connected to the rod body of the threaded rod 21.

[0039] At the bottom surface inside the wireless charging case 1, a charging component 23 is further provided. A first power supply docking plug 24 is also provided on the charging component 23. A power supply head 25 is provided inside the wireless charging case 1, and the power supply head 25 is not in contact with the charging component 23. A power supply wire 26 is also provided at the vertical plane of the power supply head 25. Electrode plates 27 are provided at the vertical planes on both sides of the power supply head 25. The electrode plates 27 are made of copper. A rectangular plate 28 is fixedly connected to the upper surface of the power supply head 25, and the upper surface of the rectangular plate 28 is fixedly connected to the lower surface of the toothed plate 18. An exhaust fan 29 is also provided at the vertical plane inside the wireless charging case 1. A second power supply docking plug 31 is provided at the vertical plane of the exhaust fan 29. A rectangular groove 32 is also provided at the intersection of the wireless charging case 1 and the L-shaped fixing rod 10.

[0040] During use, when the second embodiment is moving, before the movement, the electrode plate 27 on the power supply head 25 is inserted into the first power supply docking plug 24. At this time, the power supply wire 26 is supplying power to the charging component 23. Since the rectangular plate 28 is fixedly connected to the upper surface of the power supply head 25, and the upper surface of the rectangular plate 28 is fixedly connected to the lower surface of the toothed plate 18, when the toothed plate 18 moves, the power supply head 25 will move along with the toothed plate 18, and finally will be separated from the first power supply docking plug 24 and cut off the power supply to the charging component 23. When the toothed plate 18 moves to the end, the electrode plate 27 will be inserted into the second power supply docking plug 31 to supply power to the exhaust fan 29, so that the exhaust fan 29 ventilates the inside of the wireless charging outer frame 1.

[0041] The remaining structures are the same as those of the first and second embodiments.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive.
