Description

[Technical Field]

[0001] This invention relates to a car charging bracket, and more particularly to a car wireless charging bracket that can hold a mobile terminal and wirelessly charge it. [Previous Technology]

[0002] The continuous evolution and development of technological progress has made various electronic products / devices increasingly intelligent, with higher levels of functional integration and easier operation. For example, as mobile terminals, mobile phones are becoming increasingly indispensable to people's daily lives. Map navigation, voice control, and other functions in smartphones are being used more and more frequently in daily travel, especially in driving environments.

[0003] In a driving environment, users can charge their mobile devices using the vehicle's power supply, typically by using a car-mounted clamp to secure and charge the device. Currently, car-mounted clamps with wireless charging capabilities generally have the charging cable interface located on the clamp's housing, with an external charging cable providing power to the wireless charging pad within the clamp. The clamp is usually designed to rotate, allowing users to adjust the angle or orientation of the secured mobile device. However, rotating the mobile device during charging can easily cause the charging cable to become tangled, affecting both the device's usability and driving safety.

[0004] Therefore, how to develop a vehicle-mounted wireless charging device that can hide the charging cable to prevent it from getting tangled while charging a mobile terminal, and at the same time provide consumers with the function of freely adjusting the angle or direction of the mobile terminal, has become a problem that those skilled in the art want to actively solve. [Summary of the Invention]

[0005] The purpose of this invention is to provide a wireless charging bracket for vehicles, which securely holds a mobile terminal and wirelessly charges the mobile terminal. By placing the charging cable inside the internal space of each component of the charging bracket, problems such as cable tangling or cable obstructing the screen can be prevented when rotating the mobile terminal to adjust its viewing angle.

[0006] To achieve at least one or more of the aforementioned advantages, an embodiment of the present invention provides a vehicle wireless charging bracket, comprising: a fixing component for fixing a mobile terminal, the fixing component including a wireless charging module for charging the mobile terminal; a support component for supporting the fixing component; a swivel joint connected between the fixing component and the support component, allowing the fixing component to rotate relative to the support component; and a conductive line extending from the interior of the support component, through the interior of the swivel joint, and into the interior of the fixing component, and connected to the wireless charging module.

[0010] In some embodiments, the fitting has an arc-shaped cavity for receiving the sphere, and an opening at the bottom of the arc-shaped cavity to communicate with the internal space of the fixing component.

[0011] In some embodiments, the sphere has a limiting member and the inner surface of the arc-shaped cavity has a protrusion, which is used in conjunction with the limiting member to limit the rotation range of the fitting relative to the sphere.

[0012] In some embodiments, the fixing component may be a magnetic fixing component, which fixes the mobile terminal by magnetic adsorption.

[0013] In some embodiments, the fixing component includes a clamping portion. Each end of the clamping portion is provided with a clamping member for clamping and securing the mobile terminal.

[0014] In some embodiments, the support assembly has a transmission interface inside, one end of the conductive line extends inside the support assembly and is connected to an external power source through the transmission interface.

[0015] In some embodiments, the transmission interface is an interface capable of transmitting at least power, and the interface may be a USB interface, a Type-C interface, a Lightning interface, or a cigarette lighter interface.

[0016] In some embodiments, the housing of the support assembly has an opening, one end of the conductive line extends within the support assembly and through the opening to connect to an external power source.

[0017] In some embodiments, the vehicle wireless charging bracket may further include an adsorption fixing seat, which is connected to the support assembly via a rotating connector, so that after the vehicle wireless charging bracket is fixed in the vehicle, the support assembly can rotate relative to the fixing seat.

[0024] Please refer to Figures 1 and 2. Figure 1 is an overall schematic diagram of a vehicle wireless charging bracket provided in an embodiment of the present invention, and Figure 2 is an exploded view of the components of the vehicle wireless charging bracket. To achieve at least one or more of the aforementioned advantages, an embodiment of the present invention provides a vehicle wireless charging bracket 1, which includes at least a fixing component 10, a support component 20, a steering connector 30, and a conductive line 40.

[0025] The fixing component 10 can be used to fix a mobile terminal, facilitating the driver to operate the mobile terminal while driving. The fixing component 10 includes a wireless charging module 12 for charging the mobile terminal. As shown in the figure, in one embodiment, the wireless charging module 12 includes at least a circuit board 121 and a charging pad 122, through which the mobile terminal is charged.

[0026] The support component 20 is used to support the fixed component 10. The swivel joint 30 is connected between the fixed component 10 and the support component 20, so that the fixed component 10 can rotate relative to the support component 20 to adjust the usage and / or operation angle or direction of the mobile terminal.

[0027] The conductive line 40 extends from the interior of the support component 20 through the interior of the steering joint 30 and into the interior of the fixing component 10, and then connects to the wireless charging module 12. That is, the conductive line 40 is disposed inside the vehicle wireless charging bracket 1 and supplies power to the wireless charging module 12.

[0028] Referring to Figure 3, in one embodiment, the steering joint 30 includes a spherical shaft 32 and a fitting 34. The fitting 34 is sleeved on the spherical shaft 32 and is rotatable relative to the spherical shaft 32. The spherical shaft 32 includes a spherical body 321 and a shaft 322. One end of the shaft 322 is connected to the spherical body 321, and the other end is connected and fixed to the support assembly 20. That is, the spherical shaft 32 is connected and fixed to the support assembly 20 through the shaft 322.

[0029] The spherical shaft 32 has a through hole 323. The through hole 323 passes through the spherical body 321 and the shaft 322 along the axial direction of the spherical shaft 32, and connects to the internal space of the support assembly 20. That is, the through hole 323 passes through the shaft 322 and the spherical body 321 along the direction of the shaft 322. In one embodiment, the shaft 322 is a tubular structure, the spherical body 321 has a through opening, and the opening of the shaft 322 is connected to the opening of the spherical body 321, thus forming the through hole 323.

[0030] In one embodiment, the spherical body 321 and the shaft 322 are integrally formed and then connected and fixed to the support assembly 20. Alternatively, the spherical body 321, the shaft 322, and the support assembly 20 can also be integrally formed. That is, when manufacturing the housing of the support assembly 20, a spherical shaft 32 protruding from one side of the support assembly 20 and communicating with its internal space is also manufactured simultaneously.

[0031] In one embodiment, as shown in the figure, the conductive line 40 may be an electric wire that extends from the internal space of the support component 20 through the through hole 323 to the internal space of the fixing component 10 and is connected to the wireless charging module 12 disposed in the fixing component 10 to provide power to the charging pad 122.

[0032] In one embodiment, the fitting 34 includes a clamping knob 341 and a fitting seat 342. The clamping knob 341 has an internal thread, and the fitting seat 342 has an external thread for threaded connection and fixation with the clamping knob 341. As shown in Figures 3 and 4, the clamping knob 341 has a ring structure, and the inner side of the ring structure has an internal thread. The fitting seat 342 includes a cylindrical wall extending toward the clamping knob 341, and the outer side of the cylindrical wall has an external thread. Inside the fitting seat 342, that is, at the bottom of the cylindrical wall, there is an arc-shaped cavity 3421 for accommodating the spherical body 321, and at the bottom of the arc-shaped cavity, there is an opening 3422 to communicate with the internal space of the fixing assembly 10. As shown in Figure 4, the cylindrical wall is composed of at least four threaded wall surfaces, which are made of an elastic material.

[0033] When the spherical shaft 32 is engaged with the fitting 34, the spherical body 321 located at the front end of the shaft 322 will sequentially pass through the collar structure of the clamping knob 341 and the cylindrical wall of the fitting seat 342, and arrive at and be accommodated in the arc-shaped cavity of the fitting seat 342. After the clamping knob 341 is locked onto the fitting seat 342, the spherical body 321 can be prevented from coming out of the arc-shaped cavity 3421, and the fitting 34 can rotate relative to the spherical shaft 32.

[0034] Referring to Figure 5 in conjunction with Figures 3 and 4, in one embodiment, the spherical body 321 is composed of two hemispheres with different diameters, including a front hemisphere 3211 and a rear hemisphere 3212. The rear hemisphere 3212 is directly connected to the shaft 322, while the front hemisphere 3211 is located away from the shaft 322 and faces the arc-shaped cavity 3421 of the sleeve seat 342. The diameter of the rear hemisphere 3212 is larger than the diameter of the front hemisphere 3211, resulting in a stepped height difference between the rear hemisphere 3212 and the front hemisphere 3211 at the interface.

[0035] In one embodiment, the spherical body 321 has a limiting member 3213 located on the spherical surface of the front hemisphere 3211. Furthermore, a protrusion 3423 is provided on the inner surface of the arcuate cavity 3421, which, in conjunction with the limiting member 3213, can limit the rotation range of the fitting 34 relative to the spherical body 321. That is, when the fitting 34 rotates continuously in one direction, if the protrusion 3423 on the inner surface of the arcuate cavity 3421 abuts against the limiting member 3213 on the spherical body 321, the fitting 34 can no longer continue to rotate in that direction, and can only rotate in the opposite direction or in another direction. This arrangement prevents the conductive circuit 40 from being excessively twisted and damaged when the fitting 34 rotates at an excessively large angle, thereby affecting the power supply efficiency of the charging circuit and the charging effect on the mobile terminal.

[0036] It should be noted that during rotation, the fitting 34 can drive the fixing component 10 to rotate at different angles and directions, so that the mobile terminal fixed on the fixing component 10 can rotate to the angle or direction required by the operator. However, since a conductive line 40 is also provided between the fitting 34 and the spherical body 321 to provide power to the wireless charging module 12, in order to prevent the fitting 34 from rotating excessively in the same direction, causing the conductive line 40 to be over-twisted and resulting in a break or loosening, the rotation range of the fitting 34 can be limited by the aforementioned protrusion 3423 and limiting member 3213.

[0037] Please refer to Figure 6. In one embodiment, the fixing component 10 includes a front housing 13 and a rear housing 15 that can be assembled together. The assembled internal space is used to accommodate the circuit board 121 and the charging pad 122. It should be noted that the socket 342 is directly connected and fixed to the rear housing 15 on the side near the arc-shaped cavity 3421, so that the opening 3422 at the bottom of the arc-shaped cavity 3421 directly communicates with the internal space of the fixing component 10. In one embodiment, the socket 342 and the rear housing 15 can also be integrally formed.

[0038] In one embodiment, the fixing component 10 further includes a clamping part 16 for clamping and fixing the mobile terminal. As shown in the figure, the clamping part 16 includes an upright plate structure and clamping members 161 extending laterally at the upper and lower ends of the plate structure. Part of the plate structure is fixed in the internal space after the front housing 13 and the rear housing 15 are assembled, and the two clamping members 161 protrude from the upper and lower sides of the front housing 13 and the rear housing 15 to clamp the mobile terminal. In one embodiment, the clamping member 161 is a small roller with concave and convex textures and has a certain degree of elasticity.

[0039] During the assembly of the fixing component 10, the clamping part 16, the circuit board 121, and the charging pad 122 are locked between the front housing 13 and the rear housing 15. Furthermore, the fixing component 10 may also include a plastic housing and a support pad 14, which may be sequentially disposed on the outer surface of the front housing 13. The support pad 14 is disposed on the outermost layer of the fixing component 10 to support the mobile terminal. The support pad 14 may be a soft pad with anti-slip function, a wood grain sticker, or a plastic sheet.

[0040] Referring again to Figure 2, in one embodiment, a transmission interface 22 may be provided inside the support assembly 20. One end of a wire (conductive line 40) extends into the support assembly 20 and connects to the transmission interface 22, and then connects to an external power source (not shown) through the transmission interface 22 to supply power to the wireless charging module 12. In one embodiment, the transmission interface 22 is at least capable of transmitting power, and the transmission interface 22 may be a USB interface, a Type-C interface, a Lightning interface, or a 12-volt cigarette lighter interface. As shown in the figure, a connection hole 24 is provided on the housing of the support assembly 20 to facilitate the connection of an external charging line to the transmission interface 22.

[0041] In another embodiment, if the transmission interface 22 is not provided inside the support component 20, an opening can be provided on the housing of the support component 20 so that one end of the wire passes through the opening from the support component 20 and is connected to an external power source to provide power to the wireless charging module 12.

[0042] The vehicle wireless charging bracket 1 may further include an adsorption fixing seat 50, which is connected to the support assembly 20 via a rotating connector 51, allowing the support assembly 20 to rotate relative to the adsorption fixing seat 50 after the vehicle wireless charging bracket 1 is fixed inside the vehicle. The pivotal connection between the support assembly 20 and the adsorption fixing seat 50 provides a greater range of motion for the fixing assembly 10. In the illustrated example, the rotating connector 51 can be fixed to a receiving hole on the support assembly 20 by a screw, and after locking, a hole cover is fitted onto the receiving hole. The adsorption fixing seat 50 is locked to the rotating connector 51 by a screw. In one embodiment, the adsorption fixing seat 50 has a suction cup that can be adsorbed onto a fixed or movable device inside the vehicle; the suction cup can be a plastic vacuum suction cup or a magnetic suction cup.

[0043] Referring to Figures 6 and 7, in another embodiment of the present invention, the fixing component 10' of the vehicle wireless charging bracket 1' is a magnetic fixing component, which fixes the mobile terminal by magnetic attraction. That is, the clamping part 16 can be replaced or combined with magnetic attraction to achieve the effect of fixing the mobile terminal. In this case, a magnetic component can be provided in the fixing component 10', for example, the magnetic component can be provided between the support pad 14 and the front shell 13, or between the front shell 13 and the rear shell 15, so that a mobile terminal with magnetic attraction function can be attracted and wirelessly charged.

[0044] The vehicle wireless charging bracket 1 provided by the present invention can securely hold a mobile terminal and wirelessly charge it. In particular, because the conductive line 40 extends through the interior of the support component 20 and the directional connector 30 and connects to the wireless charging module 12 within the fixing component 10, it is not necessary to provide a power transmission interface on the housing of the fixing component 10 to connect an external charging cable. As a result, even while charging, the user can freely adjust the direction or angle of the mobile terminal, and completely eliminates the problem of charging cables tangling or obstructing the screen of the mobile terminal.

[0045] The detailed description of the preferred embodiments above is intended to more clearly describe the features and spirit of the present invention, and is not intended to limit the scope of the present invention with the preferred embodiments disclosed above.
