Description

Technical Field

[0001] The present invention relates to the technical field of automotive parts, and particularly to an in-vehicle wireless charging device. Background Art

[0002] A wireless charger refers to a charger that does not use a traditional charging power cord to connect to a terminal device that needs to be charged. In recent years, the relatively popular mobile phone wireless charging method has also been transferred to cars in line with the times, bringing great convenience to people's daily travel.

[0003] However, there are also many problems with the wireless charging method. For example, the mobile phone needs to be accurately placed and fitted in the charging position of the wireless charger to ensure the best charging state of the mobile phone. Therefore, when using a wireless charger during vehicle driving, it is very easy for the mobile phone and the charger to be displaced due to the bumping of the vehicle, affecting the charging efficiency. On the other hand, the heat generated during charging is not easily dissipated, which easily leads to a shorter service life of the mobile phone and the wireless charger, and even serious safety accidents may occur.

[0004] Currently, in the prior art, the mobile phone is positioned in the charging area through a clamping mechanism, but usually it is multi-point clamping. When clamping, it is impossible to ensure that the mobile phone is stable in both the vertical and horizontal directions at the same time, and it is restricted by the size of the mobile phone when clamping the mobile phone, with poor adaptability; at the same time, most charging devices dissipate heat from the mobile phone by opening heat dissipation holes, using a passive heat dissipation method, and the heat dissipation effect is not good. Even if a heat dissipation fan is used for active heat dissipation, the air outlet is often close to the back or bottom of the mobile phone, which not only affects the charging effect of the wireless charger, but also has a poor heat dissipation effect on mobile phones with mobile phone cases. Summary of the Invention

[0005] Aiming at the defects existing in the prior art, the purpose of the present invention is to provide an in-vehicle wireless charging device to solve the problem of low charging efficiency due to unstable fixation of the device to be charged and the wireless charger in the prior art.

[0056] To make the objectives, technical solutions and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0057] The following further elaborates on the embodiments of the present invention with reference to the accompanying drawings.

[0058] As Figures 1 to 5 shown, this application provides a vehicle-mounted wireless charging device, including a base 1, a flip cover 2 and a clamping mechanism 4. The base 1 can be fixed at the front instrument panel or the co-driver instrument panel inside the vehicle. The flip cover 2 can be flipped relative to the base 1. When the flip cover 2 is flipped open at an angle with the base 1, the clamping mechanism 4 on the flip cover 2 can be used to clamp and charge the device to be charged, so as to ensure that the device to be charged can still be stably fixed in the charging area when the vehicle is bumping, thereby improving the charging efficiency.

[0059] Specifically, a receiving groove 11 is formed on the top surface of the base 1; the flip cover 2 is rotatably connected to two side walls of the receiving groove 11 and can be turned inside and outside the receiving groove 11, and a charging area 3 is provided on the flip cover 2; the clamping mechanism 4 includes two limiting members 41, a supporting member 42 and a clamping driving member 43. The two limiting members 41 are both fixedly connected to one side of the flip cover 2 close to the receiving groove 11, and are respectively located on both sides of the charging area 3 and are arranged in an "eight" shape; the supporting member 42 is located on the flared side of the two limiting members 41 arranged in an "eight" shape, and is arranged at an interval from the limiting members 41 by the charging area 3; the clamping driving member 43 is connected to the supporting member 42 and is used to provide a clamping force for the supporting member 42 to move towards the direction close to the limiting member 41, so as to cooperate with the limiting member 41 to clamp the device to be charged.

[0060] It can be understood that a charging area 3 is provided on the flip cover 2, and a WPC (Wireless Power Consortium) wireless charging module 31 can be provided at the charging area 3 to charge the device to be charged. Since the two limiting members 41 are respectively located on both sides of the charging area 3 and are arranged in an "eight" shape, and the supporting member 42 is located on the flared side of the two limiting members 41 arranged in an "eight" shape, the device to be charged can be stably clamped in the charging area 3 between the limiting member 41 and the supporting member 42, and through the two limiting members 41 arranged in an "eight" shape, the device to be charged is limited in both the vertical direction and the horizontal direction, solving the problem that when the vehicle bumps, the device to be charged is easily clamped unstably and cannot be aligned with the charging area, resulting in low charging efficiency.

[0061] In some alternative embodiments, the clamping driving member 43 can be a telescopic rod with a resilient performance towards the limiting member 41.

[0062] Optionally, the base 1 is provided with a mounting member 13 for connecting to other structures in the vehicle body. In this example, it is a mounting groove with a mounting hole, and is fixed to the vehicle body through a nut.

[0063] In some alternative embodiments, as Figures 7 to 11 shown, the flip cover 2 includes a clamping plate 21 and a back plate 22. The clamping plate 21 and the back plate 22 are buckled and connected to form a hollow cavity for setting the charging area 3. When the flip cover 2 is turned into the receiving groove 11, the back plate 22 closes the opening of the receiving groove 11.

[0064] Here, wireless charging can be realized by placing the charging module in the cavity. And when the flip cover 2 is in the closed state, the device to be charged can be directly attached to the wireless charging part, so that the wireless charging distance can be minimized and the charging efficiency can be greatly improved. The device to be charged can be charged in both the open and closed states of the flip cover 2, and the usage scenarios are more.

[0065] In this example, a plurality of card slots 221 are circumferentially provided on the side wall of the back plate 22, and L-shaped buckles 213 are provided at corresponding positions of the clamping plate 21. The back plate 22 and the clamping plate 21 are snap-connected in a snap-fastening manner. The advantage of such a setting is that it is convenient to open the cavity for installing or repairing the device.

[0066] Optionally, on the inner wall of the clamping plate 21, there is also a charging card slot 20 for clamping the WPC wireless charging module 31 to fix the wireless charging module 31 in the charging area 3.

[0067] Furthermore, as Figure 8 and Figure 10 shown, a through hole 23 is also provided at the fastening joint of the clamping plate 21 and the back plate 22. A guiding groove 214 is provided on the inner wall of the clamping plate 21. 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 groove 214 and extend to the outside of the cavity from the through hole 23 according to the guidance of the guiding groove 214 and be electrically connected to the power supply device.

[0068] In this example, the guiding groove 214 is two arc-shaped grooves arranged at intervals, and the openings of the two arc-shaped grooves face away from each other, so that the wire harness 32 will not be bent too much, resulting in displacement and wear and breakage of the wire harness 32 during the rotation of the flip cover 2.

[0069] In some alternative embodiments, at least one sliding hole 211 with a set length is provided on the clamping plate 21 at intervals along the moving direction of the supporting member 42. The clamping driving member 43 includes a coil spring 431, one end of which is connected to the inner wall of the clamping plate 21, and the other end is connected to the connecting arm 421 of the supporting member 42 passing through the sliding hole 211, so that when the coil spring 431 expands or curls, the supporting member 42 moves towards or away from the limiting member 41.

[0070] It can be understood that one end of the coil spring 431 is fixed on the upright column 215 on the inner wall of the clamping plate 21, and the other end is connected to the connecting arm 421. Taking the horizontal setting of the supporting member 42 and the base as an example, when an external force is applied downward to the supporting member 42 to expand the coil spring 431, the coil spring 431 will generate a resilient contraction force to make the supporting member 42 move towards the limiting member 41 with a clamping force, so as to cooperate with the limiting member 41 to clamp the device to be charged.

[0071] To prevent the supporting member 42 from being pulled into the cavity by the coil spring 431, enabling the supporting member 42 to cooperate with the limiting member 41 for clamping on the outer wall of the clamping plate 21. In this example, three sliding holes 211 are spaced apart. 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 arranged at intervals in sequence along the direction perpendicular to the moving direction of the supporting member 42. 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 to the coil spring 431.

[0072] In some alternative embodiments, on the inner wall of the above-mentioned clamping plate 21, a guiding plate 212 along the moving direction of the supporting member 42 is respectively provided on both sides of the sliding hole 211. The two guiding plates 212 form a sliding groove at intervals. The clamping driving member 43 further includes a sliding bracket 432, which is slidably matched with the sliding groove. The other end of the coil spring 431 is connected to the sliding bracket 432. The connecting arm 421 of the supporting member 42 passes through the sliding hole 211 to be connected to the sliding bracket 432.

[0073] It can be understood that if the coil spring 431 and the supporting member 42 are directly connected, problems such as jamming or sliding failure due to unbalanced force may occur during the movement of the supporting member 42. Therefore, in this embodiment, on the inner wall of the clamping plate 21, a guiding plate 212 is respectively provided on both sides of the sliding hole 211. The length direction of the guiding plate 212 is the same as the telescopic direction of the coil spring 431. The two guiding plates 212 and the inner wall of the clamping plate 21 form a sliding groove. A sliding bracket 432 slidably matched with the sliding groove is arranged in the sliding groove. The coil spring 431 is connected to the supporting member 42 through the sliding bracket 432, so that the supporting member 42 can only slide in the sliding groove along with the sliding bracket 432, avoiding the problem of unstable clamping of the supporting member 42.

[0074] Specifically, as Figure 14 shown, 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 on the sliding plate 4321 for clamping with the connecting arm 421 of the supporting member 42. The connecting plate 4322 is vertically connected to the side of the sliding plate 4321 away from the clamping plate 21 and is connected to the other end of the coil spring 431. A plurality of stiffening plates 4323 are further arranged between the sliding plate 4321 and the connecting plate 4322.

[0075] In order to make the supporting member 42 have a balanced force and be more stable when clamped in cooperation with the limiting member 41, in some alternative embodiments, two of the above-mentioned coil springs 431 are provided at intervals and are respectively connected to both ends of the above-mentioned sliding bracket 432. On the inner walls of the two above-mentioned guiding plates 212 close to each other, clamping grooves are formed along the moving direction of the above-mentioned supporting member 42, and both ends of the above-mentioned sliding bracket 432 are respectively slidably connected to the clamping grooves of the two above-mentioned guiding plates 212.

[0076] Of course, the number of the coil springs 431 can also be set to be more, but it is necessary to ensure that they are symmetrically arranged 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 expand and contract. The formation of the clamping grooves on the guiding plate 212 is also to further fix the sliding direction of the sliding bracket 432 in the sliding groove.

[0077] In some alternative embodiments, as Figure 13 shown, the above-mentioned supporting member 42 is a plate member with a set length, and the length direction is parallel to the bottom edge of the above-mentioned flip cover 2 connected to the above-mentioned accommodating groove 11. A U-shaped groove for placing the device to be charged is formed on the side of the above-mentioned supporting member 42 close to the above-mentioned limiting member 41; the two above-mentioned limiting members 41 are symmetrically arranged on both sides of the central axis of the above-mentioned supporting member 42.

[0078] Optionally, a plurality of anti-slip grooves arranged at intervals can also be formed on the inner wall of the U-shaped groove to further increase the friction between the supporting member 42 and the device to be charged, and at the same time enable the device to be charged to be closely attached to the charging area 3.

[0079] It can be understood that the two above-mentioned limiting members 41 are symmetrically arranged on both sides of the central axis of the above-mentioned supporting member 42. In this way, when the device to be charged is clamped, the two limiting members 41 can not only provide an adaptable space for devices to be charged with different sizes, but also make the clamping more stable. The symmetrical arrangement in an eight-character shape restricts the force and movement of the device to be charged in the vertical and horizontal directions.

[0080] For example, when charging a mobile phone, the mobile phone can be placed horizontally. 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 abuts against the inner wall of the two eight-character-shaped limiting members 41 close to the large bell mouth; when the mobile phone needs to be set up vertically, at this time, the bottom of the mobile phone is placed in the U-shaped groove of the supporting member 42, and the other side abuts against the inner wall of the two eight-character-shaped limiting members 41 close to the small bell mouth. No matter how the mobile phone is placed, it can be ensured that the mobile phone is stably clamped. Of course, it is not limited to placing a mobile phone here, and the relative positions of the limiting member 41 and the supporting member 42 can be specifically set according to the sizes of different devices to be charged, and coil springs with different stretching capabilities can be configured.

[0081] In some alternative embodiments, one side of the above-mentioned flip cover 2 is rotatably connected to the side wall of the above-mentioned accommodation groove 11 through a first rotating shaft 6, and the other side of the above-mentioned flip cover 2 is connected to a rotation driving member 5. The rotation driving member 5 includes a second rotating shaft 51 and a driving member 52. The driving member 52 drives the second rotating shaft 51 to rotate, so as to open and close the flip cover 2.

[0082] Specifically, one end of the second rotating shaft 51 passes through the side wall of the above-mentioned accommodation groove 11 and is connected to the above-mentioned flip cover 2; the driving member 52 is connected to the other end of the second rotating shaft 51 and is used to drive the second rotating shaft 51 to rotate so as to open and close the above-mentioned flip cover 2 relative to the above-mentioned accommodation groove 11.

[0083] In this example, as Figure 2 and Figure 3 shown, since the flip cover 2 includes a back plate 22 and a clamping plate 21 that are buckled with each other, two semi-circular holes are respectively opened at the corresponding positions of the clamping plate 21 and the back plate 22, and a through hole 23 connected to the above-mentioned second rotating shaft 51 is formed after buckling. A plurality of clamping blocks 24 are circumferentially spaced on the inner wall of the above-mentioned through hole 23. One end of the second rotating shaft 51 is provided with a claw 512 and is clamped with the clamping blocks 24 in the above-mentioned through hole 23; the above-mentioned driving member 52 includes a driven bevel gear 521, a driving bevel gear 522 and a motor 523. The driven bevel gear 521 is sleeved on the other end of the above-mentioned second rotating shaft 51; the driving bevel gear 522 meshes with the above-mentioned driven bevel gear 521; the output end of the motor 523 is connected to the above-mentioned driving bevel gear 522.

[0084] Preferably, three clamping blocks 24 are spaced at intervals, and the claw 512 is configured to be clamped with the clamping blocks 24. Thus, 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, so that the second rotating shaft 51 rotates. Since the second rotating shaft 51 is clamped with the flip cover 2, the flip cover 2 can be opened and closed. It should be noted that the motor 523 can rotate forward and backward so that the flip cover 2 can be opened or closed.

[0085] Here, the driving bevel gear 522 and the driven bevel gear 521 are engaged to change the transmission direction through the bevel gears, so that the motor 523 can be fixed on the side wall of the base 1, saving the occupancy rate of the space layout.

[0086] Optionally, a wire harness hole communicating with the above-mentioned cavity is opened on the first rotating shaft 6 for the 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 opened on the base 1.

[0087] In some alternative embodiments, the motor 523 can be signal-connected to the control module. The user can control the opening and closing angle of the flip cover 2 through voice or virtual buttons, so that the device to be charged is clamped in a comfortable area along with the flip cover, which can be used for vehicle navigation or other vehicle assistance functions. Here, the motor 523 can be a stepper motor to accurately control the opening and closing angle of the flip cover 2.

[0088] In some alternative embodiments, such as Figure 2 and Figure 4 shown, the above-mentioned in-vehicle wireless charging device further includes a heat dissipation mechanism 7. 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 arranged on the side wall of the accommodation groove 11 and forms an angle with the bottom wall of the accommodation groove 11, so as to face the charging area 3 when the flip cover 2 is opened. An air outlet 711 is formed on the air outlet plate 71; one end of the air duct 72 is communicated with the air outlet 711; the fan 73 is arranged at the other end of the air duct 72 for sending air to the air outlet 711.

[0089] It can be understood that in this example, the air outlet 711 is arranged opposite to the charging area 3. Therefore, the front surface of the device to be charged can be directly cooled. The air outlet 711 will not be blocked by the device to be charged or other structures, and the heat dissipation effect is better. At the same time, when the flip cover 2 is flipped into the accommodation groove 11, the back plate 22 closes the opening of the accommodation groove 11. In this way, it can also be ensured that the air outlet 711 is closed by the back plate 22 when not in use, preventing dust or impurities from entering the air outlet 711 and damaging the device.

[0090] In some alternative embodiments, the above-mentioned in-vehicle wireless charging device further includes a control module, which is signal-connected to the fan 73 and the charging module of the charging area 3, and is used to start the fan 73 when the charging module of the charging area 3 senses the device to be charged.

[0091] For example, when the wireless charging module 31 detects the device to be charged, the circuit is connected to start charging the mobile phone. At the same time, the fan 73 is started to drive the air flow to blow through the air duct 72 and the air outlet 711 to the screen of the device to be charged 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.

[0092] Furthermore, the control module is also signal-connected to the motor 523. When the device to be charged is removed, the wireless charging module 31 and the fan 73 stop working. After a few seconds of delay, the motor 523 rotates in the reverse direction to drive the flip cover 2 to close.

[0093] The working principle of the embodiment of this application is as follows: Start the motor 523 to open the flip cover 2 to an appropriate angle, place the device to be charged in the U-shaped groove of the supporting member 42, and apply a downward force to make the supporting member 42 slide downward until the device to be charged is fully attached to the charging area 3 and then release. At this time, under the action of the torsion spring 431, the supporting member 42 and the limiting member 41 cooperate with each other to clamp the device to be charged. The wireless charging module 31 detects and starts charging the device to be charged. At the same time, the fan 73 starts to directly blow air to cool the screen of the device to be charged. When the device to be charged is removed, the wireless charging module 31 and the fan 73 stop working. After a few seconds of delay, the motor 523 rotates in the reverse direction to drive the flip cover 2 to close.

[0094] An in-vehicle wireless charging device of the present invention has two limiting members respectively arranged in a V-shaped manner on both sides of the charging area 3, and the supporting member 42 is located on the flared side of the two limiting members 41 in a V-shaped manner. In this way, the device to be charged can be stably clamped in the charging area 3 between the limiting member 41 and the supporting member 42, and through the two limiting members 41 in a V-shaped manner, the device to be charged is limited in both the vertical and horizontal directions, solving the problem that when the vehicle jolts, the device to be charged is easily clamped unstably and cannot be aligned with the charging area, resulting in low charging efficiency; by setting the sliding bracket 432 and sliding in the sliding groove on the inner wall of the clamping plate 21, the problem that the supporting member 42 gets stuck or the force is unbalanced during movement and the sliding fails is avoided; the wireless charging module 31 is fixed in the cavity of the flip cover 2, so that when the flip cover 2 is in the closed state, the wireless charging module 31 and the surrounding components no longer need to be blocked by gaskets or covers at the seams. Therefore, when charging, the device to be charged can be directly attached to the wireless charging part, making the wireless charging distance minimized and greatly improving the charging efficiency. The device to be charged can be charged in both the open and closed states of the flip cover 2, with more usage scenarios; the motor 523 can also be used to adjust the opening and closing angle of the flip cover 2 relative to the base 1, improving the comfort of use; the air outlet 711 is arranged opposite to the charging area 3, so that the front of the device to be charged can be directly cooled, and the air outlet 711 is not blocked by the device to be charged or other structures, with better heat dissipation effect; at the same time, the design of the flip cover can reduce the space occupancy rate. When not in use, the flip cover can be closed, and it can also block the air outlet 711 to prevent dust or impurities from entering and damaging the components.
