Description

Technical Field

[0001] This invention belongs to the field of vehicle wireless charger technology, and in particular relates to a vehicle wireless charger with magnetic positioning function. Background Technology

[0002] Because vehicles frequently encounter complex road environments during operation, they experience periodic or sudden vibrations and bumps, which places high demands on the physical fixation and positioning stability of in-vehicle wireless chargers. Currently, existing in-vehicle wireless chargers suffer from the following technical shortcomings:

[0003] (1) Most existing vehicle wireless chargers use direct suction (such as single magnetic suction) or magnetic suction + clamping structure for fixation. Direct suction fixation lacks peripheral restraint of the mobile phone, and its shock resistance is poor. The magnetic suction + clamping structure usually relies on the sensor electric drive clamping structure to open and close automatically. Although this method can achieve lateral positioning of the mobile phone on both sides, if the sensor electric drive fails or power is cut off, its restraining effect on the mobile phone disappears, and it cannot achieve the adsorption restraint of the mobile phone.

[0004] (2) Existing vehicle wireless chargers lack effective constraints and limits on the top (corner) and front edge of the mobile phone. When the vehicle vibrates, the resulting vibration and inertial force can easily cause the mobile phone to slide upward or tilt forward, which in turn causes the wireless charging induction coil to deviate from its alignment, affecting the stability and safety of use. Summary of the Invention

[0005] The purpose of this invention is to provide a vehicle-mounted wireless charger with adsorption and positioning capabilities. Through the structural design of a U-shaped carrier shell, an arc-shaped guide plate, a heavy-duty support part, a transmission part one, a linkage plate, a transmission part two, an inclined channel, an elastic limiting part, a top corner limiting part, and gears, the invention solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: The present invention is a vehicle-mounted wireless charger for mobile phones that can be attracted and positioned, including a wireless charging body and a shell connected by fasteners; a U-shaped mobile phone positioning structure is installed on the periphery of the shell, the mobile phone positioning structure including a U-shaped carrier shell, a heavy-duty support part, a transmission part one, a linkage plate, a transmission part two, an elastic positioning part, and a top corner positioning part.

[0007] The U-shaped carrier housing has a U-shaped mounting cavity inside, with an arc-shaped guide plate fixed at its bottom inside the mounting cavity. The heavy-duty support part is symmetrically arranged inside the U-shaped carrier housing, including a heavy-duty support wheel arranged inside the U-shaped carrier housing and a guide wheel that rolls and engages with the inner wall of the arc-shaped guide plate. The transmission part is symmetrically slidably arranged at the bottom of the mounting cavity, and the heavy-duty support part slides longitudinally through the transmission part. The mounting cavity is provided with an elastic element connected to the transmission part.

[0008] The linkage disc is rotatably mounted on the inner side wall of the mounting cavity, sleeved on the first transmission part and driven by the guide groove. The first transmission part drives the linkage disc to rotate by translation. The second transmission part is located inside the mounting cavity and on both sides of the arc-shaped guide plate. The linkage disc drives the second transmission part to move through the inclined channel. The elastic limiting parts are symmetrically arranged on both sides of the U-shaped carrier shell for limiting the side and front of the mobile phone body. The top corner limiting part has a gear fixed on its top side by a rotating shaft inside the mounting cavity. The gear meshes with the corresponding second transmission part, and the top corner limiting part is fixedly connected to the rotating shaft.

[0009] In one implementation of the present invention, the outer shell is provided with insertion slots on opposite sides, and the U-shaped carrier shell is fixed with insertion rails on opposite inner side walls. The insertion rails are inserted into the corresponding insertion slots, and the U-shaped carrier shell and the outer shell are connected by fasteners.

[0010] Preferably, the bottom of the U-shaped carrier housing is provided with a horizontal slide rail that passes through the arc-shaped guide plate, the bottom of the mounting cavity is provided with a limiting groove and a translation channel, and the opposite sides of the U-shaped carrier housing are provided with mounting holes that connect to the mounting cavity.

[0011] Furthermore, the heavy-duty support part also includes a mounting seat located inside the U-shaped carrier housing, a heavy-duty support wheel rotatably located inside the mounting seat, and a support frame slidably engaged with a horizontal slide rail at the bottom of the U-shaped carrier housing on the inner side of the arc-shaped guide plate; the mounting seat is fixed to the top of the support frame, the guide wheel rotatably located on both sides of the support frame, and a linkage rod penetrating the horizontal slide rail on the surface of the arc-shaped guide plate is fixed to the bottom of the support frame.

[0012] In one embodiment of the present invention, the transmission part includes a movable seat that slides in conjunction with the limiting groove. A transmission rod with a spiral groove and an axial groove is fixed on one side of the movable seat. The spiral groove and the axial groove are connected. An elastic element disposed inside the mounting cavity is connected to the movable seat. The linkage rod slides through the movable seat and the translation channel.

[0013] More specifically, the linkage disk is rotatably connected to the mounting hole, and the inner wall of the linkage disk is provided with balls that cooperate with the spiral groove or axial groove.

[0014] In one embodiment of the present invention, the transmission part two includes a fixed seat connected to the inner wall of the mounting cavity by fasteners, a movable rod slidably passing through the fixed seat, a guide roller that engages with the inclined channel at one end of the movable rod, and a toothed structure that meshes with a gear at the other end of the movable rod.

[0015] In the above scheme, the apex corner limiting part includes a semi-circular turntable fixed to the end of the rotating shaft, and an apex corner limiting plate with a rubber pad is fixed on one side of the semi-circular turntable.

[0016] Optionally, the elastic limiting part includes an arc-shaped extrusion rod, an arc-shaped limiting plate coaxial with the arc-shaped extrusion rod is fixed on the side facing the outer shell, and a front limiting plate is fixed on the side of the arc-shaped extrusion rod away from the outer shell. Both the arc-shaped limiting plate and the front limiting plate are located inside the U-shaped carrier shell.

[0017] In the above scheme, the U-shaped carrier shell has horizontal openings on its two inner side walls, the arc-shaped extrusion rod is located inside the corresponding horizontal opening, the outer wall of the U-shaped carrier shell is fixed with a protective cover corresponding to the horizontal opening, the inner wall of the arc-shaped limiting plate is fixed with a rectangular guide plate that slides through the U-shaped carrier shell, the end of the rectangular guide plate is fixed with a connecting plate, and the outer wall of the U-shaped carrier shell is provided with an elastic element that connects to the connecting plate.

[0018] The present invention has the following beneficial effects: 1. The present invention relies on the weight of the mobile phone to compress the heavy-duty support part, so that the heavy-duty support part moving along the arc-shaped guide plate drives the transmission part to move horizontally. The horizontally moving transmission rod drives the linkage disk to rotate through the spiral groove. The inclined channel that rotates with the linkage disk pushes the guide roller at the end of the moving rod, so that the guide roller drives the moving rod to move synchronously and drives the gear to rotate through the toothed structure on the moving rod until the bottom of the mounting base abuts against the bottom of the U-shaped carrier housing. At this time, the rubber pads on the top corner limiting plates on both sides of the semi-circular turntable tightly press against the top corner of the mobile phone body, realizing the pressure and limiting of the top corners on both sides of the mobile phone body. This can reduce the impact of vehicle vibration on the mobile phone body in the charging state, weaken the upward sliding amplitude of the mobile phone body caused by vibration and inertial force, and prevent the wireless charging induction coil from deviating from the alignment, thus improving the stability and safety of use.

[0019] 2. When the bottom of the phone body contacts the smooth outer wall of the arc-shaped limiting plates on both sides, the downward-moving phone body gradually squeezes the arc-shaped limiting plates, causing the arc-shaped limiting plates on both sides to move towards the protective cover under pressure. The rectangular guide plate that moves synchronously with the arc-shaped limiting plates drives the connecting plate to move and stretches the corresponding elastic element until the phone body is installed inside the U-shaped carrier shell. At this time, the arc-shaped limiting plates on both sides are tightly attached to the sides of the phone body by means of the elastic force of the elastic element, so as to achieve pressure and limiting on both sides of the phone body. At the same time, the front limiting plates on both sides are close to the front edge of the phone body, which can achieve blocking and limiting on the front of the phone body. This multi-limiting method of the present application can effectively prevent the phone body from lateral deviation and forward tilting deviation in the charging state, and will not cause the wireless charging induction coil to deviate from the alignment.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1, please refer to Figures 1 to 10 This invention relates to a car-mounted wireless charger for mobile phones that can be magnetically attached and positioned. It includes a wireless charging body 1 and a housing 2 connected by fasteners. The wireless charging body 1 is installed in the desired position inside the car via an angle-adjustable mounting seat. This angle-adjustable mounting seat is prior art and will not be described in detail. The housing 2 is equipped with a U-shaped mobile phone positioning structure 3. The mobile phone positioning structure 3 includes a U-shaped carrier housing 4, a heavy-duty support part 7, a transmission part one 10, a linkage plate 11, a transmission part two 12, an elastic positioning part 14, and a top corner positioning part 16.

[0035] The U-shaped carrier shell 4 has a U-shaped mounting cavity 5 inside, such as Figure 3 As shown, the cover plate 40 is used to install on the front side of the U-shaped carrier housing 4 to seal the front opening of the mounting cavity 5. The cover plate 40 is connected to the U-shaped carrier housing 4 by fasteners. An arc-shaped guide plate 6 is fixed inside the mounting cavity 5 at its bottom. The heavy-duty support part 7 is symmetrically arranged inside the U-shaped carrier housing 4, including a heavy-duty support wheel 8 arranged inside the U-shaped carrier housing 4 and a guide wheel 9 that rolls and engages with the inner wall of the arc-shaped guide plate 6. The transmission part 10 is symmetrically slidably arranged at the bottom of the mounting cavity 5. The heavy-duty support part 7 slides longitudinally through the transmission part 10. An elastic element connected to the transmission part 10 is provided inside the mounting cavity 5.

[0036] The linkage disk 11 is rotatably mounted on the inner wall of the mounting cavity 5, sleeved on the transmission part 10 and driven by the guide groove. The transmission part 10 drives the linkage disk 11 to rotate by translation. The transmission part 2 12 is located inside the mounting cavity 5 and on both sides of the arc-shaped guide plate 6. The linkage disk 11 drives the transmission part 2 12 to move through the inclined channel 13. The elastic limiting part 14 is symmetrically arranged on both sides of the U-shaped carrier shell 4 and is used for limiting the side and front of the mobile phone body 15. The top corner limiting part 16 has a gear 17 fixed on its top side through a rotating shaft inside the mounting cavity 5. The gear 17 meshes with the corresponding transmission part 2 12 and is fixedly connected to the rotating shaft.

[0037] The structure of the wireless charging body 1 and the outer shell 2 in this invention is as follows: Figure 3 As shown, the outer shell 2 has insertion slots 18 on opposite sides, and the U-shaped carrier shell 4 has insertion rails 19 fixed on opposite inner side walls. The insertion rails 19 are inserted into the corresponding insertion slots 18, and the U-shaped carrier shell 4 is connected to the outer shell 2 by fasteners. Figure 2 This is a diagram showing the completed assembly structure of the U-shaped carrier shell 4 on the outer shell 2.

[0038] The specific structure of the U-shaped carrier hull 4 in this invention is as follows: Figure 6 As shown, the bottom of the U-shaped carrier housing 4 is provided with a horizontal slide 20 that passes through the arc-shaped guide plate 6, and the bottom of the mounting cavity 5 is provided with a limiting groove 21 and a translation channel 22 respectively. The U-shaped carrier housing 4 has mounting holes on opposite sides that connect to the mounting cavity 5. These mounting holes are used to install the linkage plate 11.

[0039] The specific structure of the heavy-duty support part 7 in this invention is as follows: Figure 5 and Figure 7 As shown, the heavy-duty support part 7 also includes a mounting base 23 located inside the U-shaped carrier housing 4. The heavy-duty support wheel 8 is rotatably located inside the mounting base 23. The inner side of the arc-shaped guide plate 6 is provided with a support frame 24 that slides in cooperation with the horizontal slide rail 20 at the bottom of the U-shaped carrier housing 4. Since the top of the support frame 24 passes through the horizontal slide rail 20 at the bottom of the U-shaped carrier housing 4 and the support frame 24 slides against the inner wall of the horizontal slide rail 20, the support frame 24 can slide smoothly along the inner wall of the horizontal slide rail 20. The mounting base 23 is fixed to the top of the support frame 24, the guide wheel 9 is rotatably located on both sides of the support frame 24, and the bottom of the support frame 24 is fixed with a linkage rod 25 that passes through the horizontal slide rail 20 on the surface of the arc-shaped guide plate 6.

[0040] The specific structure of the transmission unit 10 in this invention is as follows: Figure 5 and Figure 9 As shown, the transmission unit 10 includes a movable seat 26 that slides with the limiting channel 21. A transmission rod 29 with a spiral channel 27 and an axial channel 28 is fixed to one side of the movable seat 26. The spiral channel 27 and the axial channel 28 are connected. An elastic element (spring) is provided inside the mounting cavity 5 and connected to the movable seat 26. This elastic element (spring) is a conventional component and is not shown in the figure. Specifically, a fixed anchor point is fixed at one end of the limiting channel 21 at the bottom of the mounting cavity 5. A hanging pin is provided at one end of the movable seat 26 near the fixed anchor point. The elastic element is a return tension spring, and the two ends of the return tension spring are respectively connected to the fixed anchor point and the hanging pin. When the transmission unit 10 is pushed and translated by the linkage rod 25, the movable seat 26 stretches the return tension spring to store energy. When the mobile phone body 15 is pulled out, the return tension spring releases its elastic restoring force, driving the movable seat 26 and the heavy pressure support 7 to translate and reset in the opposite direction.

[0041] Linkage rod 25 slides through movable seat 26 and translation channel 22. When the heavy-duty support roller 8 moves downward under pressure, the guide roller 9 rolls down along the inner wall of the arc-shaped guide plate 6. Since the support frame 24 slides against the inner wall of the horizontal slide 20 and linkage rod 25 slides through movable seat 26, the entire heavy-duty support 7 will not tilt during horizontal movement. The heavy-duty support 7 on both sides moves closer to each other. Linkage rod 25 pushes transmission part 10 to slide along limiting groove 21. During the movement of transmission part 10, the elastic element is gradually stretched.

[0042] The specific structure of the linkage disk 11 and the transmission part 12 in this invention is as follows: Figure 5 and Figure 10 As shown, the linkage disc 11 is rotatably connected to the mounting hole, and the inner wall of the linkage disc 11 is provided with balls that cooperate with the spiral groove 27 or the axial groove 28. Figure 5 The heavy-duty support 7 and transmission part 10 are located in their final positions after being subjected to force. Initially, the balls on the linkage disc 11 are engaged in the axial groove 28, and the transmission parts 10 on both sides and the heavy-duty support parts 7 on both sides are at their farthest distance. The mounting base 23 is detached from the bottom of the U-shaped carrier housing 4.

[0043] The transmission part 2 12 includes a fixed seat 30 connected to the inner wall of the mounting cavity 5 by fasteners. A movable rod 31 is slidably disposed on the fixed seat 30. One end of the movable rod 31 is fixed with a guide roller that engages with the inclined channel 13, and the other end of the movable rod 31 is fixed with a toothed structure 32 that meshes with the gear 17. The toothed structure 32 is always in a meshing state with the gear 17.

[0044] like Figure 6 and Figure 8 As shown, the apex corner limiting part 16 includes a semi-circular turntable 33 fixed to the end of the rotating shaft, and an apex corner limiting plate 34 with a rubber pad is fixed to one side of the semi-circular turntable 33. When wireless charging of the mobile phone body 15 is required, the mobile phone body 15 is gradually inserted into the front side wall of the outer shell 2 through the upper opening of the U-shaped carrier shell 4. When the bottom of the mobile phone body 15 contacts the heavy pressure support roller 8, it begins to press down on the heavy pressure support roller 8. The heavy pressure support roller 8, which is pressed by external force, drives the guide roller 9 to roll down along the inner wall of the arc-shaped guide plate 6 with the help of the support frame 24. The heavy pressure support parts 7 on both sides move closer to each other, and the linkage rod 25 pushes the transmission part 10 to slide along the limiting groove 21 until the bottom of the mounting base 23 abuts against the bottom of the U-shaped carrier shell 4. At this time, the positions of each heavy pressure support part 7 and the transmission part 10 are as follows. Figure 5 As shown.

[0045] As the bottom of the mobile phone body 15 contacts the heavy-pressure support roller 8 and begins to press down on the heavy-pressure support roller 8, the transmission rods 29 on both sides move closer to each other, causing the spiral grooves 27 on the transmission rods 29 to gradually approach the balls on the linkage disk 11. During this process, the balls on the linkage disk 11 slide along the axial groove 28. When the top of the phone body 15 is lower than the top of the vertical semi-circular turntable 33, the balls on the linkage plate 11 slide from the axial groove 28 into the spiral groove 27. As the heavy-duty support roller 8 continues to be pressed down, the spiral groove 27 on the horizontally moving transmission rod 29 squeezes the balls, causing the linkage plate 11 to rotate. The inclined channel 13 that rotates with the linkage plate 11 pushes the guide roller at the end of the moving rod 31, causing the guide roller to move closer to the gear 17. The guide roller drives the moving rod 31 to move synchronously and drives the gear 17 to rotate through the toothed structure 32 on the moving rod 31 until the bottom of the mounting base 23 abuts against the bottom of the U-shaped carrier housing 4. At this time, the rubber pads on the surface of the corner limiting plates 34 on both sides of the semi-circular turntable 33 press tightly against the corners of the phone body 15, realizing the pressure and limiting of the corners of the phone body 15 (e.g., Figure 1 As shown, the reset spring force of the heavy-duty support 7 is less than the weight of the phone itself, which reduces the impact of vehicle vibration on the phone body 15 during charging. It weakens the upward sliding of the phone body 15 caused by vibration and inertial force, and prevents the wireless charging induction coil from misaligning, thus improving the stability and safety of use. Finally, by powering on the wireless charging body 1, the phone body 15 can be magnetically fixed to the front side wall of the outer casing 2.

[0046] When the wireless charging is complete and the phone body 15 needs to be removed, the phone body 15 can be gradually pulled upwards. The pressure on the top of the heavy support part 7 gradually decreases, and the transmission parts 10 on both sides gradually move away with the help of the elastic restoring force of the corresponding elastic elements. The reverse-moving transmission parts 10 drive the heavy support part 7 to roll upwards along the inner wall of the arc-shaped guide plate 6. The spiral groove 27 on the horizontally moving transmission rod 29 squeezes the ball, driving the linkage plate 11 to rotate in the opposite direction. The inclined channel 13 that rotates with the linkage plate 11 pushes the guide roller at the end of the moving rod 31, so that the guide roller moves away from the gear 17 and resets. The guide roller drives the moving rod 31 to move synchronously and drives the gear 17 to rotate in the opposite direction through the toothed structure 32 on the moving rod 31 until the bottom of the mounting base 23 is separated from the bottom of the U-shaped carrier shell 4 and resets. After the phone body 15 is completely pulled out from the inside of the U-shaped carrier shell 4, the elastic limiting parts 14 on both sides also reset.

[0047] Example 2, based on Example 1, such as Figures 4 to 6As shown, the elastic limiting part 14 includes an arc-shaped extrusion rod 35. An arc-shaped limiting plate 36 coaxial with the arc-shaped extrusion rod 35 is fixed to the side of the arc-shaped extrusion rod 35 facing the outer shell 2. A front limiting plate 37 is fixed to the side of the arc-shaped extrusion rod 35 away from the outer shell 2. Both the arc-shaped limiting plate 36 and the front limiting plate 37 are located inside the U-shaped carrier shell 4. The arc-shaped limiting plate 36 is used to press and limit the two sides of the mobile phone body 15, and the front limiting plate 37 is used to block and limit the front edge of the mobile phone body 15.

[0048] Furthermore, the U-shaped carrier housing 4 has horizontal openings 38 on its two inner side walls, and the arc-shaped extrusion rod 35 is located inside the corresponding horizontal opening 38. The outer wall of the U-shaped carrier housing 4 is fixed with a protective cover 39 corresponding to the horizontal opening 38. The inner wall of the arc-shaped limiting plate 36 is fixed with a rectangular guide plate that slides through the U-shaped carrier housing 4. The end of the rectangular guide plate is fixed with a connecting plate. The outer wall of the U-shaped carrier housing 4 is provided with an elastic element that connects to the connecting plate.

[0049] As the phone body 15 is gradually inserted into the front wall of the outer casing 2 through the opening at the top of the U-shaped carrier housing 4, when the bottom of the phone body 15 contacts the smooth outer walls of the arc-shaped limiting plates 36 on both sides, the downward-moving phone body 15 gradually squeezes the arc-shaped limiting plates 36, causing the arc-shaped limiting plates 36 on both sides to be pressed and move towards the protective cover 39. The rectangular guide plate that moves synchronously with the arc-shaped limiting plates 36 drives the connecting plate to move and stretches the corresponding elastic element (spring) until the phone body 15 is installed inside the U-shaped carrier housing 4. When the device is installed, the arc-shaped limiting plates 36 on both sides are pressed tightly against both sides of the phone body 15 by the elastic force of the elastic element, so as to achieve pressure and limiting on both sides of the phone body 15. At the same time, the front limiting plates 37 on both sides are close to the front edge of the phone body 15, which can block and limit the front of the phone body 15. This multi-limiting method can effectively prevent the phone body 15 from lateral deviation and forward tilting deviation in the charging state, and will not cause the wireless charging induction coil to deviate from the alignment, thus improving the stability and safety of use.
