When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0026] The present invention provides a charging device 100 with a single motor and multiple drives.

[0027] In the embodiment of the present invention, Figure 1 As shown, the single-motor coordinated multi-drive charging device 100 includes a shell 10, a first charging part 20, a second charging part 30 and a driving motor 40. The shell 10 has a accommodating cavity, and the first charging part 20 and the second charging part 30 are arranged in the accommodating cavity and can enter and exit the accommodating cavity. The first charging part 20 can be used to charge mobile phones, tablets and other devices with wireless charging functions, and the second charging part 30 is used to charge watches. The first charging part 20 is connected to the driving motor 40, and the driving motor 40 drives the first charging part 20 and the second charging part 30 to synchronously extend out of the accommodating cavity to realize charging of the electronic device.

[0028] When not in use, the first charging part 20 and the second charging part 30 are both stored in the shell 10; the entire product is small in size and easy to carry; when charging is needed, the driving motor 40 drives the first charging part 20 and the second charging part 30 to extend out of the accommodating cavity simultaneously; at this time, the first charging part 20 protrudes from the front of the shell 10, and electronic devices such as mobile phones and tablets can be magnetically attracted to the first charging part 20 for wireless or wired charging; the first charging part 20 is designed to protrude from the front of the shell 10 when charging because it is necessary to avoid the camera module on the back of the mobile phone or tablet. Usually The camera module will protrude from the back of the mobile phone; if the first charging part 20 is flush with the front of the shell, when the mobile phone is magnetically attracted to the first charging part 20, the two cannot be completely fitted together due to the height of the camera module; in the present invention, the first charging part 20 protrudes from the front of the shell 10 during charging, which just reserves a certain space for the camera module of the mobile phone, so that the mobile phone can be completely fitted together with the first charging part 20; at the same time, based on the concept of ultimate storage, the first charging part 20 of the present invention is configured as a retractable structure, which is lowered to be flush with the front of the shell 10 when not in use.

[0029] The second charging part 30 can be extended from or retracted into the side of the shell 10; after the second charging part 30 is extended out of the shell, the watch can be hung on it; the back of the watch is in contact with the second charging part 30, and the watch can be charged or placed.

[0030] The front side of the shell 10 refers to the side of the first charging part 20 facing the user, and the side of the shell 10 is perpendicular to the front side, that is, the left and right sides of the front side. When the first charging part 20 is charging a mobile phone, the mobile phone faces the user, which can facilitate the user to check the mobile phone. The second charging part 30 extends from the side and is perpendicular to the moving direction of the first charging part 20.

[0031] Among them, the driving motor 40 can drive the first charging part 20, so that the first charging part 20 has a charging state and a storage state. The in and out movement of the first charging part 20 can drive the second charging part 30 to synchronously enter and exit the storage cavity, so the second charging part 30 also has a storage state and a charging state. In this way, the first charging part 20 and the second charging part 30 can be stored and unfolded at the same time. The first charging part 20 can fit the charging device more closely during charging, and the stored device is flatter and easier to store, which reduces the size of the device. Moreover, it can meet the needs of charging multiple devices during charging, making the charging process automated and user-friendly.

[0032] According to the above embodiment, reference Figure 2 and Figure 3 The transmission assembly includes a first transmission member 50, which is connected to the driving motor 40. The side wall of the first transmission member 50 is provided with an inclined groove 51, which is arc-shaped in the horizontal direction, and the distance between the inclined groove 51 and the bottom of the first transmission member 50 gradually increases. The first charging part 20 is provided with a sliding part 21, and the sliding part 21 slides along the inclined groove 51, so that the first charging part 20 extends or retracts into the accommodating cavity as the height of the inclined groove 51 increases, so as to realize the raising of the front side of the shell 10 to charge the mobile phone. Optionally, a plurality of inclined grooves 51 are provided, and at least three inclined grooves 51 are evenly spaced on the first transmission member 50. A plurality of sliding parts 21 are provided, and at least three sliding parts 21 are respectively provided in three inclined grooves 51 to ensure the stability of the first charging part 20 during the movement. The second transmission member 60 is engaged with the first transmission member 50, and the second transmission member 60 synchronously pushes the second charging part 30 to extend or retract into the accommodating cavity through the sliding rod 61.

[0033] There are two ways in which the second transmission member 60 is engaged with the first transmission member 50. The first way is that the second transmission member 60 is arranged inside the first transmission member 50 and is engaged with the first transmission member 50, and the slide bar 61 is arranged to drive the second charging part 30. For example, Figure 4 and Figure 5The second transmission member 60 is connected to the shell 10, one end of the second transmission member 60 is engaged with the first transmission member 50, the second charging part 30 is provided with a strip groove 31, and the other end of the second transmission member 60 is provided with a slide bar 61, and the slide bar 61 is provided in the strip groove 31 to drive the second charging part 30 to extend or retract into the shell 10, wherein the second charging part 30 can move horizontally in the strip groove 31 in and out of the shell 10, or the second charging part 30 can also be provided in the strip groove 31, and the extension and retraction relative to the shell 10 can be achieved by rotation.

[0034] In the second method, the second transmission member 60 can be set as a second gear, and the second gear is arranged on the outside of the first transmission member 50 and meshed with the first transmission member 50. One end of the slide rod 61 is provided with meshing teeth, which meshes with the second transmission member 60, and the other end is rotatably connected with the second charging part 20; the second transmission member 60 rotates with the first transmission member 50 and drives the slide rod 61 to rotate. After the slide rod 61 rotates, the second charging part 20 rotates relative to the slide rod 61; due to the action of the thread, the second charging part 20 moves in a straight line and extends or retracts into the shell 10.

[0035] For example, refer to Figure 8 The second transmission member 60 is a second gear. One side gear of the second transmission member 60 is meshed with the outer side of the first transmission member 50. The other side gear of the second transmission member 60 is meshed with the slide bar 61. The other end of the slide bar 61 extends into the second charging part 30. The second transmission member 60 rotates with the first transmission member 50 and drives the second charging part 30 to move through the slide bar 61.

[0036] In this embodiment, when the driving motor 40 drives the first transmission member 50 to rotate, the sliding part 21 moves along the inclined groove 51 to make the first charging part 20 move in the vertical direction, and at the same time, the sliding rod 61 makes the second charging part 30 move synchronously in the horizontal direction through the strip groove 31, and the front side of the shell 10 has a circular opening, and the first charging part 20 enters and exits the accommodating cavity in the vertical direction through the circular opening, and one side side of the shell 10 has a rectangular opening, and the second charging part 30 enters and exits the accommodating cavity in the horizontal direction through the rectangular opening.

[0037] In this embodiment, reference Figure 6 and Figure 7 The second transmission member 60 is provided with a third gearing portion 62 , and the third gearing portion 62 is meshed with the second gearing portion 53 .

[0038] Optionally, the structure of the second transmission member 60 is not limited, and can be configured as Figure 6 Sector shape, or set to Figure 7The second transmission member 60 is an eccentric wheel, that is, the second transmission member 60 is meshed with the first transmission member 50, but the centers of the two are not at the same position. In the present embodiment, the second transmission member 60 is provided with a third toothed portion 62 at one end which is semicircular, and the other end of the second transmission member 60 extends in a direction away from the third toothed portion 62 and the width gradually decreases to achieve overall structural balance and stability.

[0039] Based on the above-mentioned embodiment, the charging device 100 with single motor and multi-drive also includes a first gear 70 and a worm 80. The worm 80 is connected to the motor shaft of the driving motor 40. The first gear 70 is arranged between the worm 80 and the first transmission member 50 and meshes with the worm 80 and the first transmission member 50. The first transmission member 50 has a first gear portion 52 and a second gear portion 53. The first gear portion 52 is arranged on the outer wall of the first transmission member 50, and the second gear portion 53 is arranged on the inner wall of the first transmission member 50. The first gear portion 52 meshes with the first gear 70, and the second gear portion 53 meshes with the second transmission member 60. The driving motor 40 rotates by driving the worm 80, and the worm 80 drives the first transmission member 50 through the first gear 70 to drive the first transmission member 50 to rotate and the second transmission member 60 to rotate synchronously. The first gear 70 and the worm 80 cooperate with each other and have efficient transmission performance. By arranging multiple transmission gears and cooperating with each other, the transmission structure can be designed to be more compact and the space utilization rate can be improved.

[0040] Based on the above embodiment, the single-motor coordinated multi-drive charging device 100 further includes a third charging unit 90, which is rotatably connected to the first charging unit 20, and the third charging unit 90 has a storage state and an unfolded state. Fig. 9 As shown, the expanded state is Fig.10 As shown, the third charging unit 90 is on the same side as the second charging unit 30 when in the retracted state. When the third charging unit 90 is rotated to the unfolded state, it is at a certain angle to the second charging unit 30 to support the first charging unit 20 and the second charging unit 30 for placement. The third charging unit 90 can charge electronic devices in the unfolded state, such as headphones, watches, etc.

[0041] In the fully expanded state, refer to Fig.10 The third charging unit 90 has a platform structure and can be placed on a plane. The first charging unit 20 charges the electronic device on the front. The second charging unit 30 extends from the side of the housing 10 and is mainly used to charge watches and bracelets. The third charging unit 90 is on the back of the housing 10 and is mainly used to charge headphones or headphone boxes. Compared with other charging brackets, the multiple charging units provided in the present invention can charge multiple devices at the same time, saving charging time.

[0042] In terms of the overall structure, the driving motor 40 is driven by the cooperation of the first transmission member 50 and the second transmission member 60 to realize the synchronous movement of the first charging part 20 and the second charging part 30. This is different from the previous movement of the bracket of the charging device. The traditional driving charging device uses a separate motor for each active device, which has a large arrangement space and high power consumption. In addition, the number of motors used is large, the noise is large, and the stacking space utilization rate is low in the structure. The single-motor coordinated multi-drive charging device 100 of the present invention only has a single motor (driving motor 40) and a gear set (a first transmission member 50 and a second transmission member 60). The characteristics of the plastic gear transmission ratio and the simple mechanical transmission are used to coordinate the movement of multiple devices. This method has low noise and a large degree of freedom in transmission design. It can reduce the use space and facilitate the appearance and structural stacking.

[0043] Further, refer to Fig.11 , the transmission ratio in this embodiment can be calculated by the formula: WA:WB=RC:RA Wherein, RA is the radius of the first transmission member 50, RB is the distance from the center of the second transmission member 60 to the slide bar 61, that is, the radius of the movement trajectory circle of the slide bar 61, and RC is the distance from the second transmission member 60 to the third gearing portion 62; The circle with RA as radius can be called circle A, the circle with RB as radius can be called circle B, and the circle with RC as radius can be called circle C; W is the angular velocity, WA is the angular velocity of circle A, i.e. the angular velocity of the first transmission member 50, WB is the angular velocity of circle B, i.e. the angular velocity of the motion trajectory of the slide bar 61; WC is the angular velocity of circle C, i.e. the angular velocity of the third gearing portion; Since the second toothed portion 53 of the first transmission member 50 is meshed with the third toothed portion 62 of the second transmission member 60, the linear velocities of the two are equal. According to V (velocity) = R (radius) W (angular velocity), the relationship can be obtained: VA=VC; WA:WC=RC:RA; Transmission ratio iBc=WA:WC=RC:RA; Since circle B and circle C share the same center, therefore: WB=WC; Therefore: WA:WB=RC:RA Therefore, under the premise that the values ​​of RA and RC are known, the ratio of the rotation angles of the first transmission member 50 and the second transmission member 60 can be obtained, that is, the rotation angle of the second transmission member 60 can be obtained according to the rotation angle of the first transmission member 50; further, according to the fan formula, the straight-line distance moved by the slide rod 61 of the second transmission member 60, that is, the straight-line distance moved by the second charging part 30, can be obtained.

[0044] This means that, according to the above relationship design, the first charging unit 20 and the second charging unit 30 can be simultaneously displaced to the maximum value under the drive of a single motor; this is also a problem that single-motor drive needs to overcome compared to multi-motor drive.

[0045] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
