Description

Technical Field

[0001] This utility model belongs to the field of charger technology, and in particular relates to a dual-mode charging stand. Background Technology

[0002] Wireless charging devices are a power supply technology that abandons the traditional wired connection method and achieves non-contact energy transfer based on the principle of magnetic resonance coupling. The core of it is to use the electromagnetic field formed by the induction coil to efficiently and safely complete the inductive power exchange between the charging base station and the terminal device.

[0003] Chinese patent application No. 201921587476.4 discloses a wireless charging bank holder, including a wireless charger body, a rotating device, a connecting rod, and a base. The wireless charger holder consists of an upper cover and a lower cover. The upper cover has a groove on which a rotatable mobile phone baffle is mounted. The mobile phone baffle is mounted in the groove of the wireless charger upper cover, and a pin passes through the groove hole of the upper cover and the hole on the mobile phone baffle. The lower cover of the wireless charger holder has a protrusion for mounting the rotating device, and the protrusion has screw holes for fixing the rotating device. The rotating device is composed of a connecting rod assembly, with rotating devices mounted at both ends of the connecting rod. The rotating device is composed of a rotating upper cover and a rotating lower cover, and the rotating device has a low groove platform for placing an anti-slip ring.

[0004] However, the above technical solutions can only charge the electronic device on the corresponding wireless charging module according to the structure of the electronic device. Since the basic models of existing electronic devices do not have wireless charging function, the above technical solutions cannot be adapted to this type of electronic device, resulting in a narrow range of applications and limited usage scenarios. Summary of the Invention

[0005] To address the shortcomings of existing technologies, a dual-mode charging stand is provided.

[0006] This utility model is achieved using the following technical solution:

[0007] A dual-mode charging stand includes a wired charging base and a built-in power supply. A wireless charging base is stacked on top of the wired charging base. The wireless charging base and the wired charging base are folded in a Z-shape by a support arm. The wired charging base has a relatively rotatable cable take-up box, and a data cable is wound inside the cable take-up box. Both the wireless charging base and the data cable are electrically connected to the built-in power supply.

[0008] When wireless charging is needed, simply place the device on the surface of the wireless charging pad; when wired charging is needed, simply insert the end of the data cable into the charging port of the device; when support is needed for the device, open the wireless charging pad so that the support arm supports the wireless charging pad to form a support frame that can hold the device, and then place the device on the wireless charging pad.

[0009] By using a support frame to separate the wired and wireless charging docks, the device can integrate wired and wireless charging modules, ensuring the stability of power output. This frees it from the limitations of a single wireless charging function, covering both wired and wireless devices, and providing users with a dual-mode collaborative power supply architecture.

[0010] Among them, the wireless charging dock is an existing type of wireless charging module with magnetic fixing function.

[0011] The support arm can be a single rod-shaped structure, a plate-shaped structure, or several rod-shaped structures arranged along the axial direction of the pivot.

[0012] Preferably, the cable retractor has a side opening for the head of the data cable to pass through, and the wired charging dock has a groove in the horizontal direction corresponding to the side opening. The width of the groove matches the width of the data cable, and the diameter of the side opening is smaller than the diameter of the head of the data cable.

[0013] By incorporating a recess in the wired charging dock, the head of the data cable is secured by the inner and side walls of the recess. This facilitates the storage and fixation of the data cable head, preventing it from being left unattended and swinging freely with the user's movements, which could lead to damage.

[0014] Preferably, the wired charging dock has a first housing and a second housing that are interlocked at both ends along the axial direction. The cable retractor is located between the first housing and the second housing. The cable retractor and the first housing are provided with a rotation positioning component. When the cable retractor is rotated by a force, the rotation positioning component can be locked. When the cable retractor rotates relative to the rotation positioning component again, the rotation positioning component in the locked state can be unlocked.

[0015] The rotating positioning component allows the data cable to extend into the cable tray at any length for user use. Compared to a fixed-length data cable, this avoids stress concentration from bending and overheating from tangling and stacking.

[0016] Preferably, the cable retractor includes a first reel and a second reel that interlock to form a cable bundle space. The first reel and the second reel are rotatably connected to the inner end faces of the first housing and the second housing, respectively. The data cable is spirally wound around the cable bundle space, thereby allowing the first reel and the second reel to rotate relative to the first housing and the second housing when the user takes out the data cable.

[0017] Preferably, the rotary positioning assembly includes a guide rail and a swinging member respectively disposed at opposite ends of the first disc and the first housing, and an elastic member disposed in the take-up box. The guide rail includes an inner guide rail and an outer guide rail with different diameters and an abutting island disposed between the inner guide rail and the outer guide rail. The inner guide rail and the outer guide rail are connected to each other, and the end of the swinging member is embedded in the connection between the inner guide rail and the outer guide rail.

[0018] When the data cable drives the take-up box to rotate, the first reel rotates relative to the first housing, causing the swinging member to slide relative to the inner and outer guide rails. When the take-up box stops rotating for the first time, the elastic member causes the take-up box to reverse. At this time, the swinging member abuts against the abutting ring and locks, preventing the take-up box from reversing, thus allowing the data cable to extend out of the take-up box at the length selected by the user.

[0019] Preferably, a central post protrudes from the center of the second disc body, and the elastic element is fixed between the tail of the data cable and the central post. The elastic element is a spring, so that the spring can accumulate elastic force when the cable take-up box rotates.

[0020] Preferably, the central column has a radial slot along the radial direction, and one end of the spring has a bent portion that is hook-shaped and passes through the radial slot.

[0021] By using a bending section combined with radial slotting, compared to gluing the spring in place, the connection between the spring and the cable retractor can be prevented from breaking during the rotation of the cable retractor, thus ensuring the connection strength of the spring.

[0022] Preferably, the first housing has a swing groove for the swing member to swing back and forth. The swing member is disposed in the swing groove, so that the swing member can be stored in the swing groove, thereby reducing the overall axial length of the device.

[0023] Preferably, the oscillating component includes a crank rotatably connected in the oscillating groove and an oscillating rod connected to the other end of the crank along its length. The axis of the oscillating rod is parallel to the rotation axis of the crank, thereby facilitating relative sliding of the oscillating rod within the inner and outer guide rails.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] By connecting the wireless charging base and the wired charging base with a support arm, the device integrates both wired and wireless charging modules, ensuring the stability of power output and freeing it from the limitations of a single wireless charging function. It is also compatible with both wired and wireless devices, expanding the user base and enabling simultaneous power supply to two devices, thus improving the power supply efficiency of the devices.

[0026] Charging and data transfer are performed via data cables, and the data cables are collected and organized using a dedicated cable tray. This improves the ability to collect and organize data cables, allowing them to flexibly meet data transfer needs over various distances while effectively preventing cabling chaos caused by excessively long cables. It also avoids stress concentration due to bending and overheating caused by stacking during winding. Attached Figure Description

[0034] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1As shown, this embodiment discloses a dual-mode charging stand, including a wired charging base 1 and a built-in power supply. A wireless charging base 3 is stacked on the upper side of the wired charging base 1. The wireless charging base 3 and the wired charging base 1 are respectively cylindrical. A support arm 2 is hinged to the upper end of the wired charging base 1. The wireless charging base 3 is provided with a storage groove for storing the support arm 2. The other end of the support arm 2 is hinged between the inner walls of the storage groove.

[0036] The wireless charging stand 3 is equipped with a magnetic component 32 and a wireless charging coil 31. Both the magnetic component 32 and the wireless charging coil 31 have the same structure as existing technologies.

[0037] The wired charging dock 1 has a first housing 11 and a second housing 12 that are interlocked at both ends along the axial direction. A cable retractor is disposed between the first housing 11 and the second housing 12. A rotatable cable retractor and a PCB board 14 disposed on and electrically connected to the cable retractor are provided between the first housing 11 and the second housing 12. The cable retractor includes a first disc 13 located on the upper side and a second disc 15 located on the lower side. The first disc 13 and the second disc 15 are coaxially arranged and interlocked. The PCB board 14 is located at the axial center position below the first disc 13 and is electrically connected through a group of contacts. The group of contacts have the same structure as in the prior art. A slip ring is provided at the lower end of the first disc 13, directly opposite the first disc 13. The upper end of the PCB board 14 is provided with three sets of parallel contacts for electrical connection with the slip ring. A data line 17 that can be electrically connected to the parallel contacts is wound between the first disc 13 and the second disc 15. The data line 17 is spirally wound in the wire bundle space formed by the first disc 13 and the second disc 15. The electrical connection method between the data line 17 and the parallel contacts is the same as that of the prior art, thereby realizing that both the wireless charging base 3 and the data line 17 are electrically connected to the built-in power supply. After the data line 17 is wound, it is clamped and fixed by the PCB board 14 located on the upper side and the second disc 15 located on the lower side. When the data line 17 extends to the outside of the wired charging base 11, it can drive the PCB board 14 and the second disc 15 to rotate.

[0038] The first housing 11 has a window 111 for storing the data cable 17. The cable take-up box has a groove 121 in the horizontal direction corresponding to the position of the window 111. The groove 121 of the cable take-up box has a side opening 122 for the head of the data cable 17 to pass through. The width of the groove 121 matches the width of the data cable 17. The groove 121 has a protrusion 1211 for increasing the friction between the data cable 17 and the head of the data cable 17. The diameter of the side opening 122 is smaller than the diameter of the head of the data cable 17.

[0039] The first housing 11 has a swing groove for the swinging member to swing back and forth. The swinging member is located in the swing groove and includes a crank 18 rotatably connected in the swing groove and a swing rod 19 connected to the other end of the crank 18 in the length direction. The axis of the swing rod 19 is parallel to the rotation axis of the crank 18.

[0040] The take-up box and the first housing 11 are provided with a rotation positioning assembly. The rotation positioning assembly includes a guide rail and a swinging component respectively located at opposite ends of the first disc 13 and the first housing 11, as well as an elastic component located inside the take-up box. The guide rail is located in the same plane as the PCB board 14 and surrounds the outside of the PCB board 14. The guide rail is a ring-shaped structure with annular grooves. The guide rail includes an inner guide rail 21 and an outer guide rail 22 with different diameters and forming a single-turn spiral. The end of the inner guide rail 21 and the outer guide rail 22 are connected at the same point. The first and last ends of the rail 22 are respectively provided with an inner ramp 211 and an outer ramp 221 for transition. An abutting island 23 is provided between the first and last ends of the inner guide rail 21 and the first and last ends of the outer guide rail 22. The inner guide rail 21, the outer guide rail 22 and the abutting island 23 are all the same as the existing technology structure. The tail of the abutting island 23 along the rotation direction of the first disc 13 is provided with a dovetail groove 231 for abutting against the swing rod 19. The inner guide rail 21 and the outer guide rail 22 are connected.

[0041] A central post 151 protrudes from the center of the second disc 15. An elastic element, a spring-loaded spring 16, is fixed between the tail of the data cable 17 and the central post 151. A radial slot 152 is formed inside the central post 151. One end of the spring-loaded spring 16 connected to the central post 151 has a bent portion, which is hook-shaped and passes through the radial slot 152. The other end of the spring-loaded spring 16 is fixedly connected to the tail of the data cable 17. It can be fixed by any existing connection method suitable for connecting the spring-loaded spring 16 and the data cable 17, and is not limited here.

[0042] When the take-up box is rotated by the applied force, the swing rod 19 slides within the outer guide rail 22. After the data cable 17 is released, the spring 16, under its own elastic force, causes the take-up box to flip, thereby causing the swing rod 19 to slide in the opposite direction within the outer guide rail 22. Since the dovetail groove 231 of the abutment island 23 is directly opposite the swing rod 19 in this direction of movement, the swing rod 19 abuts against the dovetail groove 231, locking the take-up box. When the data cable 17 is pulled again, the locked swing rod 19 slides within the inner guide rail 21, thereby unlocking. When the data cable 17 is released again, the data cable 17 is wound around the take-up box by the spring 16.
