It will be appreciated that a charging area 3 is provided on the lid 2, and a WPC (WirelessPowerConsortium) wireless charging module 31 may be provided at the charging area 3 to charge the device to be charged. Because two locating parts 41 are located the both sides of charging zone 3 respectively and are the splayed setting, and bearing piece 42 is located two locating parts 41 and is splayed horn mouth one side, treat charging equipment just like this can be stabilized the centre gripping in charging zone 3 between locating part 41 and bearing piece 42, and through two locating parts 41 that are the splayed for treat charging equipment in vertical direction and horizontal direction all by spacing, when having solved the vehicle jolt, treat charging equipment and easily the centre gripping is unstable and can't aim at the charging zone, cause the problem that charging efficiency is low.

In some alternative embodiments, the grip actuator 43 may be a telescopic rod with resilient properties back towards the stop 41.

Optionally, the base 1 is provided with a mounting member 13 for connecting with other structures in the vehicle body, in this example, a mounting groove provided with a mounting hole, and the mounting member is fixed with the vehicle body by a nut.

In some alternative embodiments, as shown in fig. 7 to 11, the cover 2 includes a clamping plate 21 and a back plate 22, where the clamping plate 21 and the back plate 22 are fastened to each other to form a hollow cavity for setting the charging area 3, and when the cover 2 is turned into the accommodating groove 11, the back plate 22 closes the opening of the accommodating groove 11.

This has the advantage of facilitating the opening of the cavity for installation or maintenance of the device.

Optionally, a charging slot 20 for clamping the WPC wireless charging module 31 is further provided on the inner wall of the clamping plate 21, so as to fix the wireless charging module 31 in the charging area 3.

Further, as shown in fig. 8 and 10, a through hole 23 is further formed at the fastening position of the clamping plate 21 and the back plate 22, and a guiding slot 214 is formed on the inner wall of the clamping plate 21, so that after the wireless charging module 31 is fixed in the charging area 3, the wire harness 32 of the wireless charging module 31 can be fixed in the guiding slot 214, and extends from the through hole 23 to the outside of the cavity according to the guiding of the guiding slot 214, and is electrically connected with the power supply equipment.

In this example, the guide grooves 214 are two arc grooves disposed at intervals, and the openings of the two arc grooves are opposite to each other, so that the wire harness 32 cannot be excessively bent to cause abrasion and fracture due to displacement of the wire harness 32 during rotation of the flip cover 2.

In some alternative embodiments, the clamping plate 21 is provided with at least one sliding hole 211 having a predetermined length along the moving direction of the supporter 42, and the clamping driving member 43 includes a coil spring 431 having one end connected to the inner wall of the clamping plate 21 and the other end connected to a connection arm 421 of the supporter 42 passing through the sliding hole 211, so that the supporter 42 moves toward or away from the stopper 41 when the coil spring 431 is unfolded or curled.

It will be appreciated that one end of the coil spring 431 is secured to the upright post 215 of the inner wall of the clamping plate 21 and the other end is connected to the connecting arm 421. Taking the support member 42 and the base being horizontally disposed as an example, when the support member 42 is subjected to a downward external force to expand the coil spring 431, the coil spring 431 will generate a resilient force to move the support member 42 in a direction close to the limiting member 41, so as to cooperate with the limiting member 41 to clamp the device to be charged.

In order to avoid that the supporting member 42 is driven by the coil spring 431 to be pulled into the cavity, the supporting member 42 can be matched and clamped with the limiting member 41 on the outer wall of the clamping plate 21, in this example, three sliding holes 211 are arranged at intervals, each sliding hole 211 has a set length along the moving direction of the supporting member 42, so that the supporting member 42 can be driven by the coil spring 431 to move, the three sliding holes 211 are sequentially arranged at intervals along the moving direction of the vertical supporting member 42, and three groups of connecting arms 421 of the supporting member 42 are correspondingly arranged at intervals and respectively pass through the three sliding holes 211 to be connected with the coil spring 431.

In some alternative embodiments, the inner wall of the clamping plate 21 is provided with a guide plate 212 disposed at both sides of the sliding hole 211 along the moving direction of the supporter 42, the guide plates 212 are spaced apart to form sliding grooves, the clamping driving member 43 further includes a sliding bracket 432 slidably engaged with the sliding grooves, the other end of the coil spring 431 is connected to the sliding bracket 432, and the connection arm 421 of the supporter 42 is connected to the sliding bracket 432 through the sliding hole 211.

It will be appreciated that if the coil spring 431 is directly connected to the support 42, problems may occur in that the support 42 may become stuck or unbalanced during movement and slip out of order. Therefore, in this embodiment, on the inner wall of the clamping plate 21, two guide plates 212 are respectively disposed on two sides of the sliding hole 211, the length direction of the guide plates 212 is the same as the extension direction of the coil spring 431, and two guide plates 212 and the inner wall of the clamping plate 21 form a sliding groove, a sliding bracket 432 in sliding fit with the sliding groove is disposed in the sliding groove, and the coil spring 431 is connected with the supporting member 42 through the sliding bracket 432, so that the supporting member 42 can be limited to slide in the sliding groove along with the sliding bracket 432, and the unstable clamping problem of the supporting member 42 is avoided.

Specifically, as shown in fig. 14, the sliding bracket 432 includes a sliding plate 4321 and a connecting plate 4322, the sliding plate 4321 is slidably connected in the sliding groove, a clamping hole 4320 is formed in the sliding plate 4321 and is used for being clamped with the connecting arm 421 of the supporting member 42, the connecting plate 4322 is vertically connected with one side, far away from the clamping plate 21, of the sliding plate 4321 and is connected with the other end of the coil spring 431, and a plurality of stiffening plates 4323 are further arranged between the sliding plate 4321 and the connecting plate 4322.

In order to make the bearing member 42 more stable in force balance and clamping when being clamped with the limiting member 41, in some alternative embodiments, two coil springs 431 are provided at intervals and are respectively connected to two ends of the sliding support 432, and two clamping grooves are formed on inner walls of the two guiding plates 212, which are close to each other, along the moving direction of the bearing member 42, and two ends of the sliding support 432 are respectively slidably connected to the clamping grooves of the two guiding plates 212.

Of course, the number of the coil springs 431 may be increased, but it is necessary to ensure that the coil springs 431 are symmetrically disposed on both sides of the central axis of the sliding bracket 432, so that the entire sliding bracket 432 can stably slide along the sliding groove when the coil springs 431 are extended and contracted. The guide plate 212 is also provided with a locking groove to further fix the sliding direction of the sliding bracket 432 in the sliding groove.

In some alternative embodiments, as shown in fig. 13, the supporting member 42 is a plate with a set length, and the length direction is parallel to the bottom edge of the flip cover 2 connected to the accommodating groove 11, and a U-shaped groove for placing the device to be charged is formed on one side of the supporting member 42 near the limiting member 41; the two limiting members 41 are symmetrically disposed on two sides of the central axis of the supporting member 42.

Optionally, a plurality of anti-slip grooves arranged at intervals can be further formed in the inner wall of the U-shaped groove, so that friction between the bearing member 42 and the equipment to be charged is further improved, and meanwhile the equipment to be charged can be tightly attached to the charging area 3.

It can be appreciated that the two limiting members 41 are symmetrically disposed on two sides of the central axis of the supporting member 42, so that when the device to be charged is clamped, the two limiting members 41 not only provide an adaptable space for the device to be charged with different sizes, but also make the clamping more stable. The splayed symmetrical arrangement limits the stressed movement of the equipment to be charged in the vertical direction and the horizontal direction.

For example, when the mobile phone needs to be charged, the mobile phone can be horizontally placed, at this time, one side of the mobile phone is placed in the U-shaped groove of the supporting member 42, and the other side of the mobile phone is propped against the inner walls of the two splayed limiting members 41, which are close to the large bell mouth; when the mobile phone needs to be vertically arranged, the bottom of the mobile phone is placed in the U-shaped groove of the supporting piece 42, and the other side of the mobile phone is propped against the inner walls of the two splayed limiting pieces 41, which are close to the small horn mouth. The mobile phone can be ensured to be stably clamped no matter how the mobile phone is placed. Of course, the present invention is not limited to the placement of the mobile phone, and the relative positions of the stopper 41 and the holder 42 may be specifically set according to the sizes of the devices to be charged, and coil springs having different retractilities may be provided.

In some alternative embodiments, one side of the flip 2 is rotatably connected to the side wall of the accommodating groove 11 through a first shaft 6, the other side of the flip 2 is connected to a rotation driving member 5, the rotation driving member 5 includes a second shaft 51 and a driving member 52, and the driving member 52 drives the second shaft 51 to rotate, so that the flip 2 is opened and closed.

Specifically, one end of the second rotating shaft 51 passes through the side wall of the accommodating groove 11 and is connected with the flip cover 2; the driving member 52 is connected to the other end of the second rotating shaft 51, and is configured to drive the second rotating shaft 51 to rotate so as to open and close the flip cover 2 with respect to the accommodating groove 11.

In this example, as shown in fig. 2 and 3, since the flip cover 2 includes a back plate 22 and a clamping plate 21 that are fastened to each other, two semicircular holes are formed at positions corresponding to the clamping plate 21 and the back plate 22, a through hole 23 connected to the second rotating shaft 51 is formed after fastening, a plurality of clamping blocks 24 are circumferentially spaced on an inner wall of the through hole 23, and a claw 512 is disposed at one end of the second rotating shaft 51 and is clamped with the clamping blocks 24 in the through hole 23; the driving member 52 includes a driven bevel gear 521, a driving bevel gear 522, and a motor 523, wherein the driven bevel gear 521 is sleeved on the other end of the second rotating shaft 51; the drive bevel gear 522 is engaged with the driven bevel gear 521; the output end of the motor 523 is connected to the drive bevel gear 522.

Preferably, three clamping blocks 24 are arranged at intervals, and the clamping claws 512 are configured to be clamped with the clamping blocks 24, so that when the motor 523 is started, the output end drives the driving bevel gear 522 to rotate, the driving bevel gear 522 drives the driven bevel gear 521 to rotate, the second rotating shaft 51 is enabled to rotate, and the second rotating shaft 51 is clamped with the flip cover 2, so that the flip cover 2 can be opened and closed. The motor 523 may be rotated forward and backward so that the lid 2 may be opened or closed.

Here, the driving bevel gear 522 is engaged with the driven bevel gear 521, and the driving direction is changed by the bevel gear, so that the motor 523 can be fixed to the side wall of the base 1, thereby saving space arrangement occupancy rate.

Optionally, a wire harness hole communicated with the cavity is formed in the first rotating shaft 6 and used for a wire harness 32 of the wireless charging module 31 to pass through, and a wire harness groove 12 for the wire harness 32 to pass through is formed in the base 1.

In some alternative embodiments, the motor 523 may be in signal connection with the control module, and the user controls the opening and closing angle of the flip 2 through voice or virtual keys, so that the device to be charged is clamped in a comfortable area along with the flip, and may be used for vehicle navigation or other vehicle auxiliary functions. Here, the motor 523 may employ a stepping motor to precisely control the opening and closing angle of the folder 2.

In some alternative embodiments, as shown in fig. 2 and 4, the vehicle-mounted wireless charging device further includes a heat dissipation mechanism 7, where the heat dissipation mechanism 7 includes an air outlet plate 71, an air duct 72 and a fan 73, the air outlet plate 71 is disposed on a side wall of the accommodating groove 11 and forms an angle with a bottom wall of the accommodating groove 11, so as to be opposite to the charging area 3 when the flip cover 2 is opened, and an air outlet 711 is provided on the air outlet plate 71; one end of the air duct 72 is communicated with the air outlet 711; a fan 73 is provided at the other end of the air duct 72 for supplying air to the air outlet 711.

It can be appreciated that in this example, the air outlet 711 is opposite to the charging area 3, so that the front side of the charging device can be directly cooled, and the air outlet 711 is not shielded by the charging device or other structures, so that the heat dissipation effect is better. Meanwhile, when the flip cover 2 is turned over towards the accommodating groove 11, the back plate 22 seals the opening of the accommodating groove 11, so that the air outlet 711 can be sealed through the back plate 22 when not in use, and dust or impurities are prevented from entering the air outlet 711 to damage the device.

In some alternative embodiments, the vehicle-mounted wireless charging device further includes a control module, which is in signal connection with the fan 73 and the charging module of the charging area 3, and is configured to activate the fan 73 when the charging module of the charging area 3 senses the device to be charged.

For example, when the wireless charging module 31 detects the device to be charged, the circuit is turned on to start charging the mobile phone, and meanwhile, the fan 73 is started to drive air flow to blow to the screen of the device to be charged through the air duct 72 and the air outlet 711, so as to cool the device to be charged; when the device to be charged is removed, the wireless charging module 31 and the fan 73 stop working.
