[0025] This application provides a charging device and an on-board charging equipment, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.
[0026] The applicant noted that with the rapid development of connected cars and smartphones, in-vehicle wireless charging is gradually being accepted and promoted by major OEMs due to its convenience and technological innovation. However, current in-vehicle wireless charging modules are generally large in size and expensive, and the design of charging devices needs to be more compact given the limited space inside the vehicle.
[0027] In view of the above, embodiments of this application provide a charging device aimed at overcoming at least one of the aforementioned technical problems.
[0028] Please see Figures 1 to 8 As shown, this application provides a charging device, including: a base assembly 10; a first support assembly 20 disposed on the base assembly 10; a second support assembly 30 disposed on the base assembly 10, the second support assembly 30 being disposed opposite to the first support assembly 20, a first receiving area 50 being formed between the first support assembly 20 and the second support assembly 30, the second support assembly 30 having a receiving cavity 31; and a wireless charging assembly 40 disposed in the receiving cavity 31, the wireless charging assembly 40 being disposed opposite to the first receiving area 50.
[0029] It should be understood that the stable support structure of the base assembly 10 provides support at the bottom of the first support assembly 20 and the second support assembly 30; the first accommodating area 50 can be used to place electronic devices so that the wireless charging assembly 40 can wirelessly charge the electronic devices placed in the first accommodating area 50, wherein the electronic devices include, but are not limited to, mobile phones, headphones, watches, etc., that is, the first accommodating area 50 is the charging area; the first support assembly 20 and the second support assembly 30 are used to limit and fix the first accommodating area 50 on opposite sides to define the range of the first accommodating area 50 and provide support for the electronic devices, which can be placed on the base assembly 10. The wireless charging component 40 is sandwiched between the first support component 20 and the second support component 30, or it can be placed at an angle between the first support component 20 and the second support component 30. The wireless charging component 40 is arranged opposite to the first accommodating area 50, so that the orthographic projection of the wireless charging component 40 in the horizontal direction can fall on the first support component 20, so that the space between the first support component 20 and the second support component 30 can be covered by the charging range of the wireless charging. That is, the wireless charging component 40 is used to wirelessly charge the electronic device placed in the first accommodating area 50. The wireless charging component 40 can wirelessly charge the electronic device placed in the first accommodating area 50 based on electromagnetic induction.
[0030] Through the above technical solution, the wireless charging component 40 can charge electronic devices. The electronic devices can be stably placed on the base component 10 and held between the first support component 20 and the second support component 30. This design reduces the space occupied by the device, making the device more compact, and ensures that the electronic devices remain stable during charging and are not easy to slide or fall. In addition, this application arranges the first support component 20 and the second support component 30 opposite to each other on the base component 10 and forms a first accommodating area 50 between them. The wireless charging component 40 is integrated into the accommodating cavity 31 of the second support component 30 to charge the electronic devices placed in the first accommodating area 50, making the whole device more compact and optimizing space utilization.
[0031] Please see Figure 2 As shown, in some embodiments, the charging device further includes: a third support component 60 disposed on the side of the second support component 30 away from the first support component 20, and the third support component 60 disposed on the base component 10, a second receiving area 70 is formed between the second support component 30 and the third support component 60, and the second receiving area 70 is located on the side of the wireless charging component 40 away from the first receiving area 50.
[0032] It should be understood that the second accommodating area 70 can also be used to place electronic devices, so that the wireless charging component 40 can wirelessly charge the electronic devices placed in the second accommodating area 70. These electronic devices include, but are not limited to, mobile phones, headphones, watches, etc., meaning the second accommodating area 70 is also a charging area. The third support component 60 cooperates with the second support component 30 on opposite sides to limit and fix the device, thereby defining the range of the second accommodating area and providing support for the electronic devices. The electronic devices can be placed on the base component 10 and clamped between the second support component 30 and the third support component 60, or... The device is tilted between the second support component 30 and the third support component 60. It should be noted that the first accommodating area 50 and the second accommodating area 70 are located on opposite sides of the second support component 30, and the wireless charging component 40 is located between the first accommodating area 50 and the second accommodating area 70, that is, the wireless charging component 40 is located between the first support component 20 and the third support component 60. Therefore, the wireless charging component 40 can simultaneously charge electronic devices placed in the first accommodating area 50 and the second accommodating area 70, which significantly improves charging efficiency, meets the needs of charging multiple devices at the same time, and optimizes space utilization.
[0033] Please see Figure 3 and Figure 5As shown, in some embodiments, the wireless charging assembly 40 includes: a circuit board 41; and a first wireless charging coil 42 disposed on the side of the circuit board 41 near the first support assembly 20, and the first wireless charging coil 42 is electrically connected to the circuit board 41. It should be understood that the first wireless charging coil 42 charges the electronic device placed within the first accommodating area 50.
[0034] In some embodiments, the wireless charging assembly 40 includes: a circuit board 41; a first wireless charging coil 42 disposed on the side of the circuit board 41 near the first support assembly 20, and electrically connected to the circuit board 41; and a second wireless charging coil 43 disposed on the side of the circuit board 41 opposite to the first wireless charging coil 42, and electrically connected to the circuit board 41. It should be understood that the first wireless charging coil 42 charges the electronic device placed in the first accommodating area 50, and the second wireless charging coil 43 charges the electronic device placed in the second accommodating area 70. The electronic devices placed in the first accommodating area 50 and the second accommodating area 70 can be charged simultaneously via their respective corresponding coils.
[0035] It should be noted that, in this embodiment, the wireless charging component 40 includes a wireless charging coil, which is a wireless charging transmitter. It converts the electrical energy received from the circuit board 41 into a changing magnetic field, which is then transmitted through space to the receiver of the electronic product. The specific placement of the wireless charging coil can be designed according to the corresponding electronic device being charged. The wireless charging coil can be fixed to the mounting plate with adhesive, and the wireless charging coil is fixed to a magnetic shielding sheet, which is then fixed to a support plate with adhesive to avoid mutual interference between multiple coils.
[0036] Additionally, please see Figure 1 , Figure 3 and Figure 8 As shown, in some embodiments, the wireless charging assembly 40 further includes a connector 100 connected to the circuit board 41, with one end of the connector 100 away from the circuit board 41 passing through the base assembly 10.
[0037] It should be understood that, in this embodiment, a connector 100 can be soldered onto the circuit board 41. This connector 100 passes through the base assembly 10 and connects to the corresponding power supply device. After processing by the relevant circuits arranged on the circuit board 41, the wireless charging coil can charge the electronic device placed on the charging area. The connector 100 can be, but is not limited to, a USB interface, a DC power plug, etc. It should be noted that the base assembly 10 can be a detachable upper and lower housing. The first support assembly 20, the second support assembly 30, and the third support assembly 60 are disposed on the side of the upper housing away from the lower housing. The connector 100 can pass through the lower housing and connect to the corresponding power supply device.
[0038] Please see Figure 2 As shown, in some embodiments, the first support component 20 includes: a first body 21 disposed on the base component 10; and a first boss 22 disposed on the side of the first body 21 near the second support component 30, and the first boss 22 is connected to the first body 21.
[0039] It should be understood that the first body 21 is connected to the base assembly 10, and the first boss 22 is connected to the side of the first body 21 near the second support assembly 30 to form a protruding limiting structure. The design of the first boss 22 enables it to effectively hold the electronic device placed in the first receiving area 50, that is, the electronic device is clamped between the first boss 22 and the second support assembly 30, preventing the device from sliding or shifting during charging, so that it can maintain a stable state during charging and reduce charging interruptions caused by device movement.
[0040] In some embodiments, the first boss 22 has a first surface 221 and a second surface 222 near the second support component 30. The first surface 221 surrounds the outer periphery of the second surface 222 and is connected to the second surface 222. Both the first surface 221 and the second surface 222 are outwardly convex arc surfaces, and the arc curvature corresponding to the first surface 221 is greater than the arc curvature corresponding to the second surface 222.
[0041] It is important to understand that both the first surface 221 and the second surface 222 are outwardly convex arc surfaces, making it easier for electronic devices to be placed within the first receiving area 50 and reducing wear on the electronic devices. The arc radius of the first surface 221 is greater than that of the second surface 222, which prevents excessive pressure on the device surface when the electronic device within the first receiving area 50 is clamped between the second surface 222 and the second support component 30. It should be noted that the arc radius of the first surface 221 and the second surface 222 can be designed according to the actual requirements of the solution.
[0042] Please see Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the second support component 30 includes: a second body 32 disposed on the base component 10, the second body 32 having a first space 321; a second protrusion 33 disposed on the side of the second body 32 near the first support component 20, and the second protrusion 33 connected to the second body 32, the second protrusion 33 having a second space 331, the first space 321 and the second space 331 communicating to form a receiving cavity 31; and / or, a third protrusion 34 disposed on the side of the second body 32 near the third support component 60, and the third protrusion 34 connected to the second body 32, the third protrusion 34 having a third space 341, the third space 341 communicating with the first space 321 to form a receiving cavity 31; wherein, the wireless charging component 40 is disposed in the first space 321.
[0043] Furthermore, in some embodiments, the second support component 30 includes: a second body 32 disposed on the base component 10, the second body 32 having a first space 321; a second protrusion 33 disposed on the side of the second body 32 near the first support component 20, and the second protrusion 33 being connected to the second body 32, the second protrusion 33 having a second space 331, the first space 321 and the second space 331 communicating to form a receiving cavity 31; wherein, the wireless charging component 40 is disposed in the first space 321.
[0044] In some embodiments, the second support component 30 includes: a second body 32 disposed on the base component 10, the second body 32 having a first space 321; a third protrusion 34 disposed on the side of the second body 32 near the third support component 60, and the third protrusion 34 being connected to the second body 32, the third protrusion 34 having a third space 341, the third space 341 communicating with the first space 321 to form a receiving cavity 31; wherein, the wireless charging component 40 is disposed in the first space 321.
[0045] In some embodiments, the second support component 30 includes: a second body 32 disposed on the base component 10, the second body 32 having a first space 321; a second protrusion 33 disposed on the side of the second body 32 near the first support component 20, and the second protrusion 33 connected to the second body 32, the second protrusion 33 having a second space 331, the first space 321 and the second space 331 communicating to form a receiving cavity 31; a third protrusion 34 disposed on the side of the second body 32 near the third support component 60, and the third protrusion 34 connected to the second body 32, the third protrusion 34 having a third space 341, the third space 341 communicating with the first space 321 to form a receiving cavity 31; wherein, the wireless charging component 40 is disposed in the first space 321.
[0046] It should be understood that the second support component 30 is connected to the base component 10. The first space 321 is used to place the wireless charging component 40, that is, the circuit board 41, the first wireless charging coil 42 and the second wireless charging coil 43 are set in the first space 321. The second protrusion 33 is connected to the side of the second body 32 near the first support component 20, forming a protruding limiting structure. The design of the second protrusion 33 allows the electronic device to be effectively locked between the first protrusion 22 and the second protrusion 33, so that it can maintain a stable state during charging. The first protrusion 22 has a second space 331, so that there is space between the side of the first protrusion 22 near the first support component 20 and the first wireless charging coil 42. It should be noted that the first wireless charging coil 42 is set opposite to the second space 331, so that the range of the second space 331 can completely cover the first wireless charging coil 42, preventing the second protrusion 33 from being squeezed during the placement of the electronic device, thereby avoiding damage to the charging coil. Furthermore, the first space 321 and the second space 331 are connected, which not only does not affect the charging effect of the wireless charging coil, but also provides better heat dissipation and space utilization.
[0047] Please see Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the third support component 60 includes: a third body 61 disposed on the base component 10; and a fourth boss 62 disposed on the side of the third body 61 near the second support component 30, and the fourth boss 62 is connected to the third body 61.
[0048] It is important to understand that the third body 61 is connected to the base assembly 10, and the fourth protrusion 62 is connected to the side of the third body 61 near the second support assembly 30 to form a protruding limiting structure. The design of the first protrusion 22 allows it to effectively hold the electronic device placed in the first receiving area 50, preventing the device from sliding or shifting during charging, thus maintaining a stable state during charging. In addition, the third protrusion 34 is connected to the side of the second body 32 near the third support assembly 60 to form a protruding limiting structure. The design of the third protrusion 34 allows the electronic device to be effectively held between the third protrusion 34 and the fourth protrusion 62, thus maintaining a stable state during charging. Furthermore, the third protrusion 34 has a third space 341, which can completely cover the second wireless charging coil 43, preventing the second protrusion 33 from being squeezed during the placement of the electronic device, thereby avoiding damage to the charging coil. Moreover, the second space 331 and the third space 341 are connected, which not only does not affect the charging effect of the wireless charging coil, but also provides better heat dissipation and space utilization. It should be noted that the first space 321 is connected with the second space 331 and the third space 341 to form the receiving cavity 31.
[0049] Please see Figure 2 As shown, in some embodiments, the fourth boss 62 has a third surface 621 and a fourth surface 622 near the second support component 30. The third surface 621 surrounds the outer periphery of the fourth surface 622 and is connected to the fourth surface 622. Both the third surface 621 and the fourth surface 622 are outwardly convex arc surfaces, and the arc curvature of the third surface 621 is greater than that of the fourth surface 622.
[0050] It is important to understand that both the third surface 621 and the fourth surface 622 are outwardly convex curved surfaces, making it easier to place the electronic device into the second receiving area 70 and reducing wear on the device. The curvature of the third surface 621 is greater than that of the fourth surface 622, which avoids excessive pressure on the device surface when clamping the electronic device in the second receiving area 70. It should be noted that the curvature of the third surface 621 and the fourth surface 622 can be designed according to the actual requirements of the solution.
[0051] Please see Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the charging device further includes a mounting assembly 80, which includes a first mounting plate 81 disposed between the circuit board 41 and the first wireless charging coil 42; and a second mounting plate 82 disposed between the circuit board 41 and the second wireless charging coil 43.
[0052] It should be understood that by setting mounting plates between the circuit board 41 and the first wireless charging coil 42, and between the circuit board 41 and the second wireless charging coil 43, the wireless charging coil can be placed closer to the charging area, improving the accuracy and efficiency of wireless charging, and effectively avoiding the impact on the electronic components on the circuit board 41 caused by the wireless charging coil being too close to the circuit board 41. It should be noted that when the first mounting plate 81 and the second mounting plate 82 are set on both sides of the circuit board 41, they cleverly avoid the electronic components on the circuit board 41, ensuring the compatibility and functionality between components.
[0053] Please see Figure 3 , Figure 6 and Figure 7 As shown, in some embodiments, the charging device further includes a limiting component 90, which includes a first limiting boss 91 disposed on the side of the first mounting plate 81 near the first wireless charging coil 42, the first limiting boss 91 surrounding the outer periphery of the first wireless charging coil 42; and a second limiting boss 92 disposed on the side of the second mounting plate 82 near the second wireless charging coil 43, the second limiting boss 92 surrounding the outer periphery of the second wireless charging coil 43.
[0054] It should be understood that there can be multiple first limiting protrusions 91 and second limiting protrusions 92 surrounding the corresponding wireless charging coils. The first limiting protrusion 91 is connected to the first mounting plate 81 and surrounds the first wireless charging coil 42 to limit the position of the first wireless charging coil 42, making the first wireless charging coil 42 more stable on the first mounting plate 81 and preventing displacement during use. The second limiting protrusion 92 is connected to the second mounting plate 82 and surrounds the second wireless charging coil 43 to limit the position of the second wireless charging coil 43, making the second wireless charging coil 43 more stable on the second mounting plate 82 and preventing displacement during use.
[0055] Please see Figure 1 , Figure 2 and Figure 3 As shown, the following description uses a charging device having a first support component 20, a second support component 30, and a third support component 60 as an example to illustrate the charging device of this application embodiment:

Within the second support component 30, the wireless charging component 40 is simultaneously positioned opposite the first accommodating area 50 and the second accommodating area 70. That is, the first accommodating area 50 and the second accommodating area 70 are located on opposite sides of the second support component 30, and the wireless charging component 40 is located between the first accommodating area 50 and the second accommodating area 70, that is, between the first support component 20 and the third support component 60. Thus, the wireless charging component 40 can simultaneously charge electronic devices placed in the first accommodating area 50 and the second accommodating area 70, significantly improving charging efficiency, meeting the needs of charging multiple devices simultaneously, and optimizing space utilization.
