[0051] The energy conversion component (4) comprises a shell body (41) and a transceiver coil assembly (42) inside the shell body (41); the shell body (41) of the energy conversion component (4) is fixedly connected to the chassis mounting bracket (3);

[0052] The central rotating shaft (1) passes through the interior of the housing body (41) of the energy conversion component (4), the right end of which is fixedly connected to the driving gear (5), the left end of which is fixedly connected to the circuit board component (2), and the central rotating shaft (1) is connected to the chassis mounting bracket (3) by a bearing;

[0053] The transceiver coil assembly comprises a transmitting coil (421) and a receiving coil (422); the transmitting coil (421) and the central rotating shaft (1) are relatively fixed, and the receiving coil (422) and the housing body (41) of the energy conversion component (4) are relatively fixed;

[0054] The circuit board component (2) is installed with a circuit board (21), and a conversion control device is provided on the circuit board (21). The conversion control device is connected to the transmitting coil (421) and is used to control the transmission of electric energy from the external power supply device to the transmitting coil (421);

[0055] The receiving coil (422) is connected to an external load and is used to transmit the electric energy received from the transmitting coil (421) to the external load.

[0056] The transmitting coil is driven to rotate by setting an internal rotating structure, and the outer shell does not rotate to protect the internal rotating structure and coil. It can adapt to complex and changeable environments and is suitable for applications in higher-power and higher-power devices and equipment, for example, it can charge the entire machine.

[0057] In the present invention, the circuit board component (2) and the transmitting coil (421) are both relatively fixed to the rotating central shaft (1), the driving gear (5) is driven to rotate by an external device, thereby driving the rotating central shaft (1) to rotate, and the rotating central shaft (1) drives the circuit board component (2) and the transmitting coil (421) to rotate, and the circuit board component (2) is connected to an external power supply device such as a solar cell panel. The circuit board component (2) and the transmitting coil (421) are thus adaptable to multiple changing environments.

[0058] The circuit board component (2) and the transmitting coil (421) are both relatively fixed to the central axis of rotation (1), the chassis mounting bracket (3) and the outer shell body (41) of the energy conversion component (4) are fixed, and the layout of the entire product is a design with the center as the rotating structure and the outer contour as the positioning, and the structure is more stable. Specifically, the outer shell body (41) of the energy conversion component (4) is a ring structure. The ring structure is used, and the rotating structure is accompanied by the inner part, which protects the rotating structure and provides stability for the wireless charging device.

[0059] The chassis mounting bracket (3) has a chassis, which provides a stable foundation to support the entire wireless charging device. The bracket is fixed on the chassis, and the bracket is fixedly connected to the shell body (41) by bolts (7).

[0060] Furthermore, the circuit board component (2) further comprises a circuit board housing (22), a first circuit board outer cover (23) and a second circuit board outer cover (24); the circuit board (21) is fixed in the circuit board housing (22); the first circuit board outer cover (23) is used to seal the left end of the circuit board housing (22); the second circuit board outer cover (24) is used to seal the right end of the circuit board housing (22); the second circuit board outer cover (24) is fixedly connected to the left end of the central rotating shaft (1);

[0061] The first circuit board outer cover (23) has a first wire harness through hole (25) for connecting the circuit board (21) with an external power supply device through a wire harness.

[0062] Specifically, the circuit board housing (22) is an annular structure. The annular structure is used, and a rotating structure is provided inside to protect the rotating structure, thereby providing stability for the wireless charging device. The first circuit board outer cover (23), the second circuit board outer cover (24), and the circuit board housing (22) protect the circuit board.

[0063] The transmitting and receiving coil assembly is an annular structure, and the central rotation axis (1) passes through the center of the transmitting and receiving coil assembly, that is, the transmitting coil (421) and the receiving coil (422) are both annular, and the central rotation axis (1) passes through the center of the transmitting coil (421) and the receiving coil (422). The annular design ensures that no matter how the transmitting coil (421) rotates, it is always arranged relative to the receiving coil (422).

[0064] Furthermore, a heat sink (26) is provided inside the circuit board housing (22), and a plurality of heat sink teeth (27) are provided in an area on the circuit board housing (22) corresponding to the heat sink (26), and a vent is formed between two adjacent heat sink teeth (26).

[0065] Heat is dissipated through ventilation openings.

[0066] Furthermore, the energy conversion component (4) comprises a first intermediate carrier (423) and a second intermediate carrier (424) arranged opposite to each other;

[0067] The receiving coil (422) is fixed to the housing body (41) via a first intermediate carrier (423);

[0068] The transmitting coil (421) is relatively fixed to the central rotating shaft (1) via a second intermediate bearing member (424).

[0069] Specifically, the energy conversion component (4) further includes a first ferrite (425) and a second ferrite (426) arranged opposite to each other;

[0070] The receiving coil (422) is wound on the first ferrite (425), and the first ferrite (425) is supported on the first intermediate support (423).

[0071] The transmitting coil (421) is wound on the second ferrite (426), and the second ferrite (426) is carried on the second intermediate carrier (424).

[0072] The first intermediate carrier (423) and the second intermediate carrier (424) both have grooves, the first ferrite (425) is installed in the groove of the first intermediate carrier (423), and the second ferrite (426) is installed in the groove of the second intermediate carrier (424).

[0073] Furthermore, the receiving coil (422) and the transmitting coil (421) are arranged opposite to each other with a gap (space) therebetween.

[0074] The receiving coil and the transmitting coil are placed opposite to each other with a gap in between. The gap is mainly used to cooperate with the coil coupling to ensure that there is no possibility of contact during rotation and that they can rotate stably without collision.

[0075] The first ferrite (425) and the second ferrite (426) are partially notched for the installation of the corresponding wire rights. In addition, the first ferrite (425) and the second ferrite (426) can be made into a spliced ​​structure for the purpose of easy installation and meeting functional requirements, thereby reducing costs.

[0076] Furthermore, the interior of the central rotating shaft (1) is a hollow structure (11), and a connecting wire harness between the transmitting coil (421) and the conversion control device on the circuit board (21) passes through the hollow structure.

[0077] The central rotating shaft is a hollow structure, which is mainly used for installing the wiring harness. In the actual working process, the wiring harness and the coil rotate together with the central rotating shaft to ensure that the wiring harness is not entangled and the winding is not broken.

[0078] Specifically, the central rotating shaft (1) is provided with a wire harness inlet hole and a wire harness outlet hole, so that the wire harness connected to the conversion controller enters and exits the transmitting coil, and then is connected to the conversion controller to realize a loop. The wire harness is received in the hollow structure through the wire harness inlet hole and the wire harness outlet hole, and the wire is rotated together with the entire central rotating shaft to ensure that the wire harness will not be entangled during the rotation of the entire internal transmitting coil, and at the same time ensure that the wire harness can be stably connected.

[0079] Furthermore, it also includes a protective cover (6) fixedly connected to the right end of the housing body (41) of the energy conversion component (4);

[0080] The protective cover (6) and the central rotating shaft (1) are connected via a bearing; the right end of the central rotating shaft (1) passes through the protective cover (6) and is fixedly connected to the driving gear (5).

[0081] The protective cover (6) and the central rotating shaft (1) are connected via a bearing, and the central rotating shaft (1) and the chassis mounting bracket (3) are connected via a bearing and the bearing is close to the circuit board component (2), which is equivalent to having fixed bearings at both ends of the shell body, thereby ensuring the stability of the rotation of the entire central rotating shaft (1).

[0082] A bearing fixing seat (31) is provided on the chassis mounting bracket (3), a first bearing (32) is provided on the bearing fixing seat (31), and the central rotating shaft (1) and the chassis mounting bracket (3) are connected via the first bearing (32). Furthermore, the energy conversion component (4) includes at least two groups of transceiver coil assemblies;

[0083] The housing body (41) is composed of housing units (411) having the same number as the number of groups of the transceiver coil components and an intermediate housing (412) connecting two adjacent housing units (411);

[0084] For each housing unit (411), a group of transceiver coil assemblies are arranged inside, and the receiving coil (422) in the transceiver coil assembly is fixed to the housing unit (411) via a first intermediate carrier (423);

[0085] The left end of the second intermediate carrier (424) carrying the transmitting coil in the leftmost housing unit (411) is fixed to the central rotating shaft (1);

[0086] The second intermediate bearing members (424) of two adjacent housing units (411) are connected together via a meshed first twisted member (427) and a second twisted member (428);

[0087] The first twisted member (427) and the second twisted member (428) are engaged with each other inside the intermediate housing (412) between two adjacent housing units (411).

[0088] Each receiving coil (422) corresponds to a first ferrite (425) for winding and a first intermediate carrier (423) for fixing the first ferrite (425), so as to be fixedly connected to the inside of the housing unit where it is located.

[0089] Each transmitting coil (422) corresponds to a second ferrite (426) for winding and a second intermediate carrier (424) for fixing the second ferrite (426). The first transmitting coil (422) on the left is fixed to the central rotating shaft (1) through the second intermediate carrier (424). Then, the two adjacent second intermediate carriers (424) are meshed and driven by the first twisted piece (427) and the second twisted piece (428), so that each transmitting coil rotates synchronously, and the synchronous rotation of two or more groups of transmitting coils is realized.

[0090] Specifically, the circuit board housing (22) is annular (cylindrical), the first circuit board outer cover (23) and the second circuit board outer cover (24) are disc-shaped, the housing unit (411) and the intermediate housing (412) are annular (cylindrical), and the protective cover (6) is disc-shaped, so that the entire wireless charging device looks like a cylinder.

[0091] The left and right ends of the intermediate housing (412) have flange structures, the left and right ends of the housing unit have flange structures, and the housing unit (411) and the intermediate housing (412) are flange-connected by bolts (7). The left flange structure of the leftmost housing unit (411) is connected to the chassis installation by bolts (7), and the right flange structure of the rightmost housing unit (411) is connected to the protective cover (6) by bolts (7).

[0092] The internal structure of the shell body can be a single-layer transceiver coil assembly, but is not limited to a single layer. It can also be a multi-layer transceiver coil assembly. Each layer of the transceiver coil assembly has a receiving coil and a transmitting coil installed oppositely. The two transceiver coils are respectively wound on their own supporting ferrite frames. The ferrite is also a ring structure that wraps the coil.

[0093] Furthermore, the energy conversion component (4) includes two sets of transceiver coil assemblies;

[0094] The two transmitting coils (421) of the two groups of transmitting and receiving coil assemblies are between the two receiving coils (422); the second intermediate bearing member (424) respectively bearing the transmitting coils (421) is between the two transmitting coils (421);

[0095] Each second intermediate carrier (424) has a second wire harness through hole (4241), and the series wires of the two transmitting coils (421) are connected through the second wire harness through hole (4241).

[0096] The transmitting coil (421) is connected in series with the transmitting coil to achieve series connection.

[0097] Specifically, the leftmost housing unit (411) is provided with a third wiring harness through-hole, and the receiving coil (422) in the leftmost housing unit (411) is connected to an external load device through the third wiring harness through-hole (4221). Furthermore, temperature sensors are respectively provided near the transmitting coil (421) and on the circuit board (21) for collecting temperature data;

[0098] The conversion control device is also connected to the temperature sensor for adjusting the transmission power of the transmitting coil according to the temperature data.

[0099] Specifically, providing a temperature sensor near the transmitting coil (421) means providing a temperature sensor on the second ferrite.

[0100] If the product is working in space, the overall heat dissipation method is mainly radiation heat dissipation, without conduction heat dissipation, so the heat generated during use cannot be dissipated in a faster way. For example, adding heat dissipation glue and increasing the heat dissipation area are not very effective in improving the heat generation of the product. For this reason, the present invention adds a temperature sensor during the design process, which can automatically reduce the working power and thus reduce the temperature when the temperature reaches a certain set value.

[0101] Since the layout of the wireless charging device of the present invention is that the outer shell is fixed and does not rotate, and the inner shell rotates with the rotation of the central shaft, such assembly has very high requirements for precision, and has high requirements for the tightening torque of the screws, the installation sequence, the installation and layout position and sequence of the wiring harness, etc. At the same time, there are strict installation standards for the winding of the transceiver coil and the fixing of the ferrite (fragile), and the requirements for the sequence of steps in the installation and layout assembly process are also very high.

[0102] The present invention makes the two circuit board components and the energy conversion component rotate synchronously through the rotation of the central axis, and hides the connecting harness in the hollow structure of the central shaft, effectively avoiding the problem of the harness being entangled during the rotation process. At the same time, through the fixed structure, the receiving coil and the transmitting coil maintain a certain gap, thereby ensuring the stability and safety of the rotation.

[0103] The present invention provides a wireless charging device for application scenarios such as aerospace, automobiles, and industry. In particular, in the special application environment of aerospace, the energy generated is transmitted in a non-contact manner, effectively reducing the disadvantages caused by contact. Wireless charging is very advantageous in the application environment of space. It can maintain stable power to transmit energy during movement, and can still work stably in a variety of changing environments. It is a charging method that other charging methods cannot provide.

[0104] Compared with the prior art, the differences and advantages of the present invention are as follows:

[0105] (1) In the prior art, the receiving coil and the transmitting coil are fixed during the charging process, while the transmitting coil of the present invention can rotate. In addition, from the appearance, the outer shell is fixed.

[0106] (2) The present invention can not only realize the assembly of one transceiver coil assembly, but also realize the assembly of two or more transceiver coils. Each housing unit and the internal transceiver coil assembly, the first and second intermediate receiving parts, and the first and second ferrites constitute a modular structure. The two modular structures are fixedly connected in the external housing units through the intermediate housing, and the transmission connection of the second intermediate receiving parts between the transmitting coils is realized through two twisted parts inside. One second intermediate receiving part drives the other second intermediate receiving parts to rotate accordingly, thereby realizing the synchronous rotation of all the transmitting coils.

[0107] (3) General wireless charging adopts the method of fixing after docking, but this design can meet the 360° all-round charging mode, which can meet the charging requirements at any angle and can operate effectively whether in the charging process or not.

[0108] (4) The main application scope of the present invention involves the fields of aerospace, and also involves automobile and industrial applications. A small part of the existing rotation methods are small model rotation structures such as mobile phone charging, and the rotation structures are not the same.

[0109] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
