Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and in particular to a wireless charging motion mechanism, a rear armrest box, and an automobile. Background Technology

[0002] Most of the models developed by various OEMs now have wireless charging capabilities.

[0003] In-vehicle wireless charging modules enable passengers' mobile phones to be charged more effectively while driving, overcoming the cumbersome constraints of multiple charging connectors and allowing mobile phones to be charged wirelessly directly, thus enhancing the passenger experience and enriching the functionality of the vehicle's interior.

[0004] Existing wireless charging methods include: ① concealed charging, fixed inside the armrest box or sliding storage compartment; ② open charging, fixed under the top or rear upper cover; and ③ plug-in charging, fixed inside the top cover or seat. For driver charging, these three methods have no major drawbacks. However, for passengers charging their phones, since they are not driving and can safely operate their phones, the fixed top or rear upper cover prevents them from using their phones while charging. For example, if the wireless charger in the second-row armrest is laid flat, passengers cannot operate their phones while charging, or if they can, the convenience is poor. Furthermore, for temporary video conferences, the phone needs to be held upright, and none of the above three methods allow for simultaneous charging and video conferencing. Also, when the phone is out of power, it's impossible to handle work messages and tasks while wirelessly charging; therefore, these methods cannot meet the needs of passengers in various situations. Summary of the Invention

[0005] To address the aforementioned issues, this invention proposes a wireless charging motion mechanism that cleverly enables the wireless charging module to move, allowing it to rotate freely at various angles. This, combined with the angle of the seat back, allows occupants to more easily operate their mobile phones. Without interfering with wireless charging, the tilt angle can be adjusted for online video conferencing, making work more mobile and convenient. Furthermore, for entertainment functions during wireless charging, the mechanism can be manually rotated by up to ±90° to allow for landscape use, fully meeting the needs of occupants to charge their phones while using them in the vehicle.

[0006] This invention proposes a wireless charging motion mechanism, including a wireless charging assembly, a forward and reverse drive motor, a base, an X-axis transmission mechanism, a Z-axis flipping mechanism, and a ±90° manual flipping mechanism.

[0007] The wireless charging assembly includes a wireless charging base and a wireless charging unit. The wireless charging base and the wireless charging unit are connected by a ±90° manual flipping mechanism for rotation limit. For the entertainment functions of the mobile phone during wireless charging, the wireless charging mechanism can also be manually rotated up to 90° clockwise or counterclockwise to use the mobile phone in landscape mode, fully meeting the needs of passengers to charge their mobile phones while using them in the vehicle.

[0008] The forward and reverse drive motor is fixed at the end of the base. The forward and reverse drive motor is connected to the end of the X-axis transmission mechanism, which converts the clockwise or counterclockwise rotation of the forward and reverse drive motor into the forward and backward translational movement of the X-axis transmission mechanism, thereby indirectly providing power to adjust the tilt angle of the front end of the wireless charging assembly in the Z-axis (vertical direction).

[0009] The front end of the X-axis transmission mechanism is pivotally connected to the rear end of the lower surface of the wireless charging assembly. The wireless charging assembly is slidably connected to the base through the pivot of the X-axis transmission mechanism, and the wireless charging assembly can move back and forth along the length of the base.

[0010] One end of the Z-axis flip mechanism is hinged to the front end of the base, and the other end of the Z-axis flip mechanism is hinged to the middle of the lower surface of the wireless charging assembly. The Z-axis flip mechanism, in conjunction with the X-axis transmission mechanism, can make the front end of the wireless charging assembly flip in the Z direction.

[0011] The base includes a motor mounting bracket and a charging assembly mounting bracket. The charging assembly mounting bracket is a flat plate structure, with its left and right side walls bent downwards to form horizontal U-shaped grooves. The motor mounting bracket includes a connecting surface and a motor fixing part integrally formed with the connecting surface at its rear end. The end of the forward and reverse drive motor is fixed to the vertical plane of the motor fixing part. The left and right ends of the connecting surface are respectively fitted into the horizontal U-shaped grooves of the charging assembly mounting bracket, and the connecting surface and the charging assembly mounting bracket are fixed by bolts. X-direction limiting protrusions are protruding on the left and right sides of the rear end of the upper surface of the charging assembly mounting bracket. Long sliding limiting holes are horizontally opened on the opposite side walls of the two X-direction limiting protrusions. The two ends of the pivot of the X-direction transmission mechanism are slidably fitted into the long sliding limiting holes of the two X-direction limiting protrusions. Hinged arms are protruding on the left and right sides of the front end of the upper surface of the charging assembly mounting bracket. The two sides of one end of the Z-direction flipping mechanism are rotatably hinged to the hinged arms.

[0012] The X-axis transmission mechanism includes a transmission mechanism body and a pivot. A fork-shaped rotating connecting arm protrudes from the front end of the transmission mechanism body. The pivot is horizontally inserted and fixed on the fork-shaped rotating connecting arm, and the left and right ends of the pivot are exposed outside the left and right outer walls of the fork-shaped rotating connecting arm. The two ends of the pivot are respectively slidably accommodated in the long sliding limiting holes of two X-axis limiting protrusions. A hole with internal threads is opened on the rear end face of the transmission mechanism body. A screw is fixed on the shaft of the forward and reverse drive motor. The screw is rotated and sleeved in the hole with internal threads in the transmission mechanism body.

[0013] The Z-axis flipping mechanism is an inverted rectangular box structure. The rear side wall of the inverted rectangular box structure has a missing part, and a three-section bushing is provided on the missing part. A first hinge shaft is fixedly fitted in the three-section bushing. The lower surface of the wireless charging assembly is rotatably fitted onto the exposed part of the first hinge shaft. The lower end of the front side wall of the inverted rectangular box structure has a second hinge shaft. The left and right ends of the second hinge shaft are rotatably connected to the hinge arm, and the Z-axis flipping mechanism can be rotatably fastened to the front part of the upper surface of the charging assembly fixing bracket.

[0014] The ±90° manual flipping mechanism is a cross roller bearing. The inner ring of the cross roller bearing is fixed to the middle of the inner bottom wall of the wireless charging base by bolts, and the outer ring of the cross roller bearing is fixed to the middle of the lower surface of the wireless charging unit by bolts. The wireless charging unit is rotatably suspended above the wireless charging base by the cross roller bearing. The wireless charging unit and the wireless charging base are limited and fixed by limiting devices that are circumferentially set on corresponding surfaces.

[0015] The wireless charging assembly includes a wireless charging upper housing, a wireless charging module, and a wireless charging lower housing. The upper surface of the wireless charging upper housing has a phone receiving groove. The lower surface of the wireless charging upper housing has symmetrically protruding positioning protrusions. The lower surface of the wireless charging upper housing has symmetrically arranged snap-fit ​​clips on both sides. The wireless charging module is fitted to the lower surface of the wireless charging upper housing corresponding to the phone receiving groove. The wireless charging module is limited in position by the positioning protrusions and is screwed to the lower surface of the wireless charging upper housing. The snap-fit ​​clips are respectively attached to the left and right side walls of the wireless charging module. The inner bottom wall of the wireless charging lower housing has snap-fit ​​slots corresponding to the snap-fit ​​clip positions, and the snap-fit ​​clips engage with the corresponding snap-fit ​​slots. A limiting device is provided on one side wall and the adjacent inner bottom wall of the wireless charging lower housing. This limiting device includes a button with a return spring, a spring limiting seat, a hook, and at least one hook base. One end of the button with the return spring is sleeved... A button with a return spring protrudes from one side wall of the lower housing of the wireless charging unit. The other end of the button is elastically limited to a spring-limiting seat set on the inner bottom wall of the lower housing. The upper end of the hook is fixed to the middle of the button with the return spring. The lower part of the hook passes through the inner bottom wall of the lower housing and can be horizontally moved outside the lower bottom wall of the lower housing. At least one hook seat is set on the inner surface of the wireless charging base. At least one hook seat is set on the rotation radius of the hook body, and the hook body can engage with each hook seat. The rear ends of the lower housing and the wireless charging base are respectively provided with avoidance design parts corresponding to the X-direction limiting protrusion and the fork-shaped rotating connecting arm, so that when the front end of the wireless charging assembly rotates upward, the corresponding positions of the rear ends of the lower housing and the wireless charging base will not contact the X-direction limiting protrusion and the fork-shaped rotating connecting arm to prevent the wireless charging assembly from rotating in the Z direction. The lower surface of the wireless charging base is provided with sleeves corresponding to the pivot and the first hinge axis.

[0016] The base also includes a motor mounting bracket housing, which is screwed onto the connecting surface, housing the connecting surface and the charging assembly mounting bracket within the motor mounting bracket housing.

[0017] The upper shell of the wireless charging housing has a matching anti-slip pad inside the phone receiving groove; the rear outer edge of the phone receiving groove of the upper shell of the wireless charging housing has a recessed groove, and a phone shield is rotatably connected between the two side walls of the recessed groove. The phone shield is restricted to rotate by the limiting springs on the two end shafts, so as to ensure that the wirelessly charged phone will not fall out of the phone receiving groove when the wireless charging assembly is flipped in the Z direction.

[0018] A rear armrest box includes a rear armrest box sheet metal and a wireless charging motion mechanism, wherein the rear armrest box sheet metal is screwed and fixed to the motor mounting bracket housing.

[0019] An automobile includes a body and a rear armrest box, the rear armrest box being located within the body.

[0020] Beneficial effects

[0021] This invention allows the wireless charging module to rotate freely at a certain angle, and in conjunction with the angle of the seat back, it enables passengers to operate their mobile phones more easily. Without affecting the wireless charging of the phone, passengers can also conduct online video conferences by adjusting the tilt angle, making work more mobile and convenient. For the entertainment functions of the phone, the wireless charging mechanism can also be manually rotated by up to ±90° to use the phone in landscape mode, fully meeting the needs of passengers to charge their phones while using them in the vehicle.
