[0027] Mounting bracket for mounting inside a vehicle body, the mounting bracket having an upward-facing receiving groove;

[0028] A charging unit is installed within the receiving slot. The upper surface of the charging unit is used to accommodate a device to be charged, enabling wireless coupling between the charging unit and the device. The charging unit is movably installed within the receiving slot, having a pressurized position and a disengaged position.

[0047] Currently, wireless charging modules in most car models are located on the center console's secondary dashboard. To facilitate phone access, the wireless charging area is typically a large, open recess. However, this recessed design significantly impacts the flatness and aesthetics of the center console's secondary dashboard.

[0048] This invention provides a wireless charging device for vehicles and a car, wherein, Figures 1 to 9 This is a schematic diagram of an embodiment of the wireless charging device for vehicles provided by the present invention.

[0049] Please see Figures 1 to 5The vehicle wireless charging device 100 includes a mounting base 1, a charging unit 2, and a driving assembly. The mounting base 1 is used to install itself in the vehicle body and has an upward-facing receiving groove 11. The charging unit 2 is installed in the receiving groove 11, and the upper end surface of the charging unit 2 is used to place the device to be charged so that the charging unit 2 and the device to be charged can be wirelessly coupled. The charging unit 2 is movably installed in the receiving groove 11 to have a pressure-activated position and a separation-activated position. In the pressure-activated position, the charging unit 2 moves to the left end being below the opening of the receiving groove 11. In the separation-activated position, the charging unit 2 moves to the upper end being flush with the opening of the receiving groove 11. The driving assembly is installed on the mounting base 1 and is used to drive the charging unit 2 to switch between the pressure-activated position and the separation-activated position.

[0050] In the technical solution provided by this invention, when a device to be charged needs to be charged, the device to be charged is placed on the upper surface of the charging part 2. The driving component drives the charging part 2 to move, causing the charging part 2 to move to the pressure-activated position. Since the charging part 2 moves to a position where its left end is below the opening of the receiving groove 11, the side wall of the receiving groove 11 can limit the device to be charged, preventing the device from flying out of the receiving groove due to inertia when the vehicle is in motion. The charging part 2 is positioned at an angle, with its left end lower than the opening of the slot 11. This allows the charging part 2 to be tilted, facilitating the removal of the device after charging. Once the device is fully charged, it separates from the upper surface of the charging part 2. The driving assembly then moves the charging part 2 from the pressure position to the separation position. In the separation position, the charging part 2 moves until its upper surface is flush with the opening of the receiving slot 11, thus covering the receiving slot 11, improving aesthetics, ensuring flatness, and achieving good results.

[0051] There are various types of drive components that drive the charging unit 2 to switch between the pressed active position and the disengaged active position. For example, the drive component may include a crank-rocker mechanism. Specifically, in the embodiments of this application, referring to... Figure 3 and Figure 5The charging unit 2 is provided with a connecting part 4, and the connecting part 4 has a strip-shaped hole 41 extending in the front-back direction. The strip-shaped hole 41 extends in the left-right direction. The driving assembly includes a swinging part 31 and a driving mechanism 32. The swinging part 31 is located near the left end of the charging unit and extends in the vertical direction. The lower end of the swinging part 31 is rotatably mounted in the receiving groove 11 via a rotating shaft a extending in the front-back direction. A sliding column 311 is provided on the upper side of the swinging part 31. The sliding column 311 is slidably mounted in the strip-shaped hole 41. The driving mechanism 32, which is mounted in the receiving groove 11, drives the swinging part 31 to rotate, causing the upper end of the swinging part 31 to swing, and causing the sliding column 311 to slide in the strip-shaped hole 41, thereby driving the left end of the charging unit 2 to move up and down, so that the charging unit 2 switches between the pressure position and the separation position. Since the strip-shaped hole 41 extends in the left and right directions, when the sliding column 311 drives the left end of the charging part 2 to move up and down, the charging part 2 as a whole has a left and right movement stroke. In this way, the gap between the side wall of the charging part 2 and the side wall of the receiving groove 11 can be reduced when the charging part 2 moves, so as to prevent impurities and the like from falling in and affecting the switching of the charging part 2 between the pressure position and the separation position.

[0052] Specifically, refer to Figure 6 , Figure 7 as well as Figure 9 The swing part 31 has a circular arc rack 312 in the middle, which extends circumferentially along the axis a of rotation of the swing part 31. The drive mechanism 32 includes a linear drive structure 321 and a drive rack 322. The linear drive structure 321 has a drive part 3211 with a left-right travel. The drive rack 322 extends left-right and one end of the drive rack 322 is connected to the drive part 3211. The drive rack 322 meshes with the circular arc rack 312. When the drive part 3211 moves left-right, it drives the drive rack 322 to move left-right. When the drive rack 322 moves, it causes the circular arc rack 312 to rotate. The rotation of the circular arc rack 312 drives the swing part 31 to rotate around its axis a. The structure is compact.

[0053] It should be noted that the linear drive mechanism 32 can be of various types, such as a cylinder, hydraulic cylinder, electric push rod or linear motor, etc. Specifically, this application does not limit it.

[0054] To ensure smooth movement of the charging unit 2, refer to... Figure 3 , Figure 4 and Figure 5 A guide structure is also provided between the charging part 2 and the side wall of the receiving groove 11. The guide structure includes a guide groove 51 inclined to the right from top to bottom and a guide post 52 adapted to the guide groove 51. One of the guide groove 51 and the guide post 52 is provided on the charging part 2 and the other is provided on the side wall of the receiving groove 11. The adaptation of the guide groove 51 and the guide post 52 makes the charging part 2 move smoothly and effectively when the driving component drives the charging part 2 to move.

[0055] It should be noted that the two ends of the guide groove 51, which are arranged opposite each other in the vertical direction, simultaneously limit the guide post 52, thereby restricting the lifting and lowering stroke of the charging part 2. The two guide structures are arranged at intervals in the vertical direction, so that the angle of the charging part 2 is limited under the action of the two guide structures, avoiding the charging part 2 from being too large or too small, which would affect the charging effect.

[0056] Furthermore, two guide structures are provided, which are respectively located on both sides of the swing part 31. With this arrangement, the charging part 2 is subjected to uniform force through the combined action of the two guide structures, and the charging part 2 moves smoothly when the driving component drives the charging part 2 to move.

[0057] Specifically, the guide groove 51 is provided on the side wall of the receiving groove 11 and extends through the mounting base 1. The guide post 52 is provided on the charging part 2 and extends through the receiving groove 11 and out of the mounting base 1. This arrangement avoids the guide post 52 from detaching from the guide groove 51 after long-term use, thus affecting the guiding effect.

[0058] Furthermore, referring to Figure 1 and Figure 6 A transmission block 521 is provided on the guide post 52. The transmission block 521 extends vertically and has multiple meshing teeth 5211 on its side. The drive assembly also includes a damping gear 33, which is mounted on the mounting base 1 and can selectively mesh with a portion of the multiple meshing teeth 5211. By providing the damping gear 33, the resistance of the transmission block 521 during its swing process is increased, the rotational speed of the guide post 52 is reduced, and the movement of the charging unit 2 is made smooth. This avoids abnormal noise caused by the charging unit 2 moving too fast or the charging device colliding with the inner wall of the receiving groove 11 due to inertia.

[0059] It should be noted that the damping gear 33 is existing technology, and its specific structure and working principle will not be described in detail here.

[0060] To facilitate the retrieval of the device to be charged, a limiting structure is provided between the side wall of the receiving groove 11 and the left end of the charging part 2. The limiting structure restricts the downward movement of the left end of the charging part 2, allowing the left end of the charging part 2 to move to a suitable depth, thereby facilitating the retrieval of the device to be charged. The structure is simple.

[0061] Specifically, the limiting structure includes a limiting platform protruding from the side wall of the receiving groove 11 and an abutting part located at the left end of the charging part 2. The abutting part abuts against the limiting platform, thereby limiting the downward movement of the left end of the charging part 2. The structure is simple and effective.

[0062] To slow down the descent speed of the charging unit 2, the vehicle wireless charging device 100 also includes a buffer 7. The buffer 7 is disposed between the bottom wall of the receiving groove 11 and the charging unit 2. Through the buffering effect of the buffer 7, the downward movement speed of the charging unit 2 is slowed down, avoiding excessive descent speed, abnormal noise, or collision of the device to be charged, which has a good effect.

[0063] Furthermore, the buffer 7 includes a torsion spring, which is installed in the receiving groove 11. One end of the torsion spring abuts against the bottom wall of the receiving groove 11, and the other end of the torsion spring abuts against the lower end face of the charging part 2. This arrangement utilizes the elastic force of the torsion spring to slow down the downward movement speed of the charging part 2. The structure is simple and the effect is good.

[0064] It should be noted that in other embodiments, the buffer 7 can also be set as a sponge, spring, rubber band, etc., but this application does not limit it in this respect.

[0065] Specifically, the vehicle wireless charging device 100 also includes a sensor electrically connected to a control device. The control device is mounted on the mounting base 1, and the sensor is mounted on the charging unit 2. When the sensor detects that the device to be charged is placed on the upper surface of the charging unit 2, the sensor feeds back the detected signal to the control device. The control device controls the drive assembly to operate, thereby driving the charging unit 2 to switch from the separated active position to the pressed active position. Conversely, when the sensor detects that the device to be charged is separated from the upper surface of the charging unit 2, the sensor feeds back the detected signal to the control device. The control device controls the drive assembly to operate, thereby driving the charging unit 2 to switch from the pressed active position to the separated active position, thus realizing automation and intelligence.

[0066] It should be noted that there are various types of sensors, such as pressure sensors, gravity sensors, infrared sensors, proximity switch sensors, etc. Specifically, this application does not limit them.

[0067] The present invention also proposes a car, which includes the vehicle wireless charging device 100 as described above. The car adopts all the technical solutions of the above embodiments, and therefore has the same technical effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0068] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made under the concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
