[0023] The applicant notes that wireless charging technology is widely used in numerous electronic products. The wireless charging process relies on the coupling between the charging component and the built-in receiving coil of the device being charged. Therefore, the efficiency and performance of wireless charging are significantly affected by the distance and position between the charging component and the device. Furthermore, with the rapid development of connected cars and smartphones, in-vehicle wireless charging modules are gradually being accepted and promoted by major automakers due to their convenience and technological innovation. However, current in-vehicle wireless charging modules on the market primarily focus on meeting the needs of smartphones that support wireless charging, without fully considering the charging compatibility needs of emerging electronic products such as wireless headphones and smartwatches.
[0024] In view of this, embodiments of this application provide a charging device aimed at overcoming at least one of the aforementioned technical problems.
[0025] Please see Figures 1 to 5 As shown, this application provides a charging device, including: a housing assembly 10, which has a receiving cavity 20 and at least one charging area on the housing assembly 10; a circuit board 30 disposed in the receiving cavity 20; a wireless charging component 40 disposed on the side of the circuit board 30 near the charging area and electrically connected to the circuit board 30, and the wireless charging component 40 is aligned with the charging area; and a support plate 50 disposed between the circuit board 30 and the wireless charging component 40.
[0026] It should be understood that in this embodiment, the circuit board 30, the wireless charging component 40, and the support plate 50 are placed in the receiving cavity 20 within the shell assembly 10, allowing the shell assembly 10 to provide support, waterproofing, and dustproofing. Furthermore, the receiving cavity 20 within the shell assembly 10 effectively integrates the circuit board 30, the wireless charging component 40, and the support plate 50, resulting in a compact overall device structure. Additionally, the support plate 50, positioned between the circuit board 30 and the wireless charging component 40, allows the wireless charging component 40 to be more closely attached to the charging area, improving the accuracy and efficiency of wireless charging. The shell assembly 10 has at least one charging area, allowing at least one electronic device to be placed on it, enabling simultaneous charging of multiple electronic devices. Each charging area holds one electronic device, and each charging area corresponds to one wireless charging component 40. It should be noted that in this embodiment, a connector can be soldered onto the circuit board 30, passing through the shell assembly 10 and connecting to the corresponding power supply device. After processing by the relevant circuitry on the circuit board 30, the wireless charging component 40 can then charge the electronic devices placed in the charging areas.
[0027] Please see Figure 2 and Figure 4 As shown, in some embodiments, the wireless charging assembly 40 includes a wireless charging coil 41, which is fixed on the support plate 50 and electrically connected to the circuit board 30. It should be understood that the wireless charging coil 41 included in the wireless charging assembly 40 in this embodiment is a wireless charging transmitter, which converts the electrical energy received from the circuit board 30 into a changing magnetic field for transmission to the receiving end of the electronic product. It should be noted that the specific placement of the wireless charging coil 41 can be designed according to the corresponding electronic device being charged. The wireless charging coil 41 can be fixed to the support plate 50 with adhesive, and the wireless charging coil 41 is also fixed to a magnetic shielding sheet, which is also fixed to the support plate 50 with adhesive to avoid mutual interference between multiple coils.
[0028] Please see Figure 1 and Figure 2 As shown, in some embodiments, the housing assembly 10 includes an upper housing 11 and a lower housing 12, which are connected to form a receiving cavity 20, with the charging area disposed on the upper housing 11. It should be understood that the receiving cavity 20, located between the upper housing 11 and the lower housing 12, contributes to the structural stability and compactness, and facilitates the installation and maintenance of the components. The combination of the upper housing 11 and the lower housing 12 provides a protective outer shell, ensuring that the internal components are protected from external environmental influences during use.
[0029] Please see Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, at least one charging area is a first charging area 13. The housing assembly 10 has a first surface 16 and a second surface 17 facing away from the wireless charging assembly 40. The first charging area 13 is formed on the side of the first surface 16 and the second surface 17 away from the wireless charging assembly 40. The first surface 16 surrounds the outer periphery of the second surface 17 and is connected to the second surface 17. Both the first surface 16 and the second surface 17 are outwardly convex arc surfaces. The wireless charging assembly 40 is aligned with the second surface 17. The arc curvature corresponding to the first surface 16 is greater than the arc curvature corresponding to the second surface 17. It should be understood that the first charging area 13 can be used to charge the smartwatch. The smartwatch body 51 is placed on the second surface 17, and the watch strap is placed on the first surface 16 to ensure a good fit. The smartwatch body can be stably placed on the second surface 17, while the watch strap naturally fits on the first surface 16. It should be noted that the curvature of the first surface 16 and the second surface 17 can be customized according to different smartwatch models. The height of the second surface 17 can be higher than the height of the first surface 16. It can be fixed to the first surface 16 by a pad, which has a second surface facing away from the first surface 16 to ensure optimal fit and charging effect.
[0030] Please see Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the charging device further includes a first limiting component 60, which includes a plurality of first limiting members 61. The first limiting members 61 are disposed around the outer periphery of the second surface 17, and one end of the first limiting member 61 near the housing component 10 is connected to the housing component 10.
[0031] For example, in the case of two first limiting members 61, the two first limiting members 61 can be provided on opposite sides of the outer periphery of the second surface 17 to securely fix the body of the smartwatch; in the case of four first limiting members 61, two first limiting members 61 can be provided in two directions intersecting on the outer periphery of the second surface 17, with two first limiting members 61 in each direction located on opposite sides, thereby further enhancing the fixing effect on the body of the smartwatch; and so on, the design can be made according to actual needs to ensure the stability and safety of the smartwatch body during charging. By flexibly configuring the number and position of the limiting members, the charging device can adapt to smartwatches of different sizes and shapes, providing a more reliable charging experience.
[0032] In some embodiments, when the main body of the smartwatch is rectangular, the radial cross-section of the first limiting member 61 located at the four corners of the smartwatch can be L-shaped to facilitate the stabilization of the main body of the smartwatch; the first limiting member 61 can be made of a deformable material, such as silicone, plastic, rubber, etc., to better stabilize the electronic device.
[0033] Please see Figure 1 and Figure 2 In some embodiments, at least one charging area is a second charging area 14, and the housing assembly 10 has a third surface 18 facing away from the wireless charging assembly 40. The second charging area 14 is formed on the side of the third surface 18 away from the wireless charging assembly 40, and the third surface 18 is a slope.
[0034] In some embodiments, wireless earphone cases or mobile phones, or other electronic devices, can be placed on the third surface 18 for charging. The slope provides natural support, allowing the electronic device to rest securely against the bottom of the slope. This design effectively prevents the device from sliding or falling during charging, ensuring that the device is always in the optimal charging position. It should be noted that the inclination angle of the slope can be flexibly designed according to actual needs. By adjusting the angle of the slope, it can accommodate different types and sizes of devices, meeting the needs of users in various usage scenarios.
[0035] Please see Figure 1 and Figure 2 In some embodiments, at least one charging area is a third charging area 15, and the housing assembly 10 has a fourth surface 19 facing away from the wireless charging assembly 40. The third charging area 15 is formed on the side of the fourth surface 19 away from the wireless charging assembly 40, and the fourth surface 19 is planar.
[0036] In some embodiments, wireless earphone cases or mobile phones, or other electronic devices, can be placed on the fourth surface 19 for charging. The planar structure provides a stable charging platform suitable for devices that do not require additional support. It should be understood that, through the design of the first surface 16, the second surface 17, the third surface 18, and the fourth surface 19, these charging areas can provide users with diverse charging options to meet the needs of different devices and usage environments.
[0037] Please see Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the support plate 50 includes a body 51 and a boss 52. The boss 52 is located on the side of the body 51 near the wireless charging component 40 and is connected to the body 51. The wireless charging component 40 is located on the side of the boss 52 near the charging area. It should be understood that the boss 52 can be aligned with the second surface 17, the third surface 18, or the fourth surface 19, allowing the wireless charging component 40 to fit more closely to the charging area, improving the accuracy and efficiency of wireless charging. It should be noted that the position and number of the bosses 52 can be designed according to the actual needs of the solution.
[0038] Please see Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the support plate 50 includes a body 51 and an inclined plate 53. The body 51 is connected to the inclined plate 53, and the inclined plate 53 is aligned with the charging area. The inclined plate 53 has a fifth surface 531 near the charging area, and the wireless charging component 40 is disposed on the fifth surface 531. The fifth surface 531 is parallel to the third surface 18. It should be understood that the inclined plate 53 can be aligned with the third surface 18. By making the fifth surface 531 parallel to the third surface 18, the wireless charging component 40 placed on the fifth surface 531 is more closely attached to the charging area corresponding to the third surface 18, improving the accuracy and efficiency of wireless charging. It should be noted that the inclined plate 53 can be connected to the side of the body 51 near the charging area, or it can be spliced to the body 51, depending on the actual needs of the solution.
[0039] Please see Figure 1 and Figure 2 As shown, in some embodiments, it further includes: a second limiting component 70, including a second limiting member 71 and a third limiting member 72, the second limiting member 71 and the third limiting member 72 intersect and are disposed on the outer periphery of the charging area, and the ends of the second limiting member 71 and the third limiting member 72 near the shell component 10 are connected to the shell component 10.
[0040] It should be understood that both the second limiting member 71 and the third limiting member 72 are limiting plates. The intersection of the second limiting member 71 and the third limiting member 72 can be that their extension directions are perpendicular to each other, or they can intersect at a certain angle. The specific design can be based on the actual shape of the charging area. The intersection of the second limiting member 71 and the third limiting member 72 and their placement on the outer periphery of the charging area can be on two adjacent sides of the outer periphery of the surface corresponding to the charging area. That is, one end of the second limiting member 71 and one end of the third limiting member 72 are connected. The end of the second limiting member 71 away from the connection with the third limiting member 72 and the end of the third limiting member 72 away from the connection with the second limiting member 71 extend towards the two adjacent sides of the outer periphery of the surface corresponding to the charging area, respectively.
[0041] In some embodiments, the second limiting member 71 and the third limiting member 72 intersect and are disposed on the outer periphery of the third surface 18, and the second limiting member 71 or the third limiting member 72 is disposed at the end with the lowest height in the third surface 18.
[0042] In some embodiments, the second limiting member 71 and the third limiting member 72 intersect and are disposed on the outer periphery of the fourth surface 19, and the second limiting member 71 or the third limiting member 72 is disposed on any two adjacent sides of the fourth surface 19.
[0043] It should be understood that the second limiting component 70 includes a second limiting member 71 and a third limiting member 72. The second limiting member 71 and the third limiting member 72 intersect and are disposed on two adjacent sides of the charging area. They limit the electronic device placed in the charging area to ensure that the device remains stable during charging, but do not limit the range of the charging area, so as to accommodate more types and sizes of electronic devices.
