Description

Technical Field

[0001] This application belongs to the field of electronic product technology, and specifically relates to a wireless charging device. Background Technology

[0002] With the increasing number of smartphones and other smart mobile terminals that support wireless charging technology, such as smartwatches, smart earphones, and smart glasses, users are increasingly needing to charge multiple smart mobile terminals simultaneously. In this case, one-to-one wireless charging devices have inherent drawbacks: first, they require multiple wireless charging stands, but the stands themselves are bulky, making it inconvenient to store and carry if there are too many; second, they can only charge multiple devices sequentially one by one, resulting in long charging times and low charging efficiency. Summary of the Invention

[0003] The purpose of this application is to provide a wireless charging device that can solve the problem of low charging efficiency in existing charging technologies when multiple devices have charging needs.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] In a first aspect, embodiments of this application provide a wireless charging device, including:

[0006] A base; a track bracket fixed to the base; a slide rail movably connected to the track bracket; and N antennas movably connected to the slide rail, where N is an integer greater than 1.

[0007] The slide rail reciprocates between a first state and a second state relative to the track support; the antenna reciprocates on the slide rail to adjust the antenna's transmission position and transmission direction.

[0008] In this embodiment, the wireless charging device includes: a base; a track bracket fixed on the base; a slide rail movably connected to the track bracket; and N antennas movably connected to the slide rail, where N is an integer greater than 1. By reciprocating between a first state and a second state relative to the track bracket, and by reciprocating between the antennas on the slide rail, the transmitting position and transmitting direction of the antennas are adjusted to optimize the energy transmission efficiency between the transmitting antenna and the receiving antenna of the device to be charged. This allows for the selection of the most efficient and successfully paired transmitting antenna for each device to be charged, achieving simultaneous charging of multiple devices through N antennas while ensuring charging efficiency. This solves the problems of long charging time and low charging efficiency when multiple devices have charging needs, and is also easy to store and carry. Attached Figure Description

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0030] The control method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0031] Please refer to Figures 1 to 12 This invention provides a wireless charging device, comprising:

[0032] A base 1; a track support 22 fixed on the base 1; a slide rail 23 movably connected to the track support 22; and N antennas 3 movably connected to the slide rail 23, where N is an integer greater than 1. The slide rail 23 reciprocates between a first state and a second state relative to the track support 22. The antennas 3 reciprocate on the slide rail 23 to adjust the transmission position and transmission direction of the antennas 3.

[0033] The type of antenna is not limited here. As an optional implementation, all antennas can be millimeter-wave antennas. Millimeter-wave antennas emit millimeter waves, which have the characteristics of large bandwidth, low propagation attenuation, and minimal impact from natural light and heat radiation sources, resulting in relatively low energy loss during transmission. This minimizes the energy loss of millimeter waves, thereby further improving the charging efficiency of the device to be charged.

[0034] It should be noted that, taking mobile phones as an example, due to the influence of antenna directionality, the energy transmission efficiency of the transmitting antenna and the receiving antenna is different when they are in different positions and angles. When the two are close together and the angle is good, the energy transmission efficiency is high. When the two are far apart or the angle is poor, the energy transmission efficiency is low, and there may even be a situation where they cannot be properly matched.

[0035] In this embodiment, the reciprocating movement of the slide rail 23 relative to the track support 22 between a first state and a second state, and the reciprocating movement of the antenna 3 on the slide rail, adjust the transmitting position and direction of the antenna 3, i.e., adjust the transmitting angle of the antenna 3, and adjust the positional relationship between the antenna 3 and the device to be charged 5. This optimizes the energy transmission efficiency between the transmitting antenna 3 and the receiving antenna of the device to be charged 5, maximizing the coupling between the transmitting antenna 3 and the receiving antenna. This improves the flexibility of placing the device to be charged 5, reduces energy loss, and increases the efficiency of wireless charging. Therefore, this embodiment can solve the problems of long charging time and low charging efficiency when multiple devices have charging needs, and is also convenient for storage and carrying.

[0036] It should be noted that the reciprocating motion of the slide rail 23 and the antenna 3 can be controlled based on user input, such as the user manually adjusting the position of the slide rail 23 and the antenna 3; or it can be automatically controlled based on the placement position of the device 5 to be charged.

[0037] As an example, when charging multiple devices, the wireless charging device adjusts the position of antenna 3 to determine M target antennas from the N antennas that are successfully matched with the multiple devices to be charged and whose charging efficiency is greater than a preset threshold, where M is a positive integer less than or equal to N.

[0038] In one embodiment, the device further includes a control unit and a position detection unit; wherein the position detection unit is communicatively connected to the control unit, and the position detection unit is used to acquire the position information of the device 5 to be charged; the control unit is used to control the slide rail 23 to reciprocate between a first state and a second state relative to the track support 22 according to the position information, and to control the antenna 3 to reciprocate on the slide rail 23.

[0039] In this embodiment, the position detection unit can obtain the placement information of the device to be charged 5, and the control unit can automatically control the slide rail 23 and the antenna 3 to move according to the position information, so as to adjust the transmission angle of the antenna 3 and the positional relationship between the antenna 3 and the device to be charged 5.

[0040] In one embodiment, the slide rail 23 is an annular structure, and the first state and the second state are two states in which the slide rail 23 rotates 180 degrees relative to the track support 22 around its radial axis.

[0041] like Figure 1 and 2 As shown, the slide rail 23 is rotatably connected to the track support 22; by rotating the slide rail 23 relative to the track support 22, the movement trajectory of the slide rail 23 surrounds the platform 21.

[0042] It should be noted that ring structures include: circular rings, square rings, and polygonal rings with regular or irregular side lengths, etc.

[0043] As another example, the slide rail 23 can also be at least two curved structures, such as a semi-circular ring, a "U" shape, a "U" shape, a "U" shape, etc.

[0044] In this embodiment, the slide rail 23 rotates 180 degrees relative to the track support 22 during its rotation, allowing the slide rail 23 to surround the platform 21. This, combined with the sliding of the antenna 3 on the slide rail 23, enables the antenna 3 to emit radiation at an all-around angle surrounding the platform 21. Since the adjustable emission angle of the antenna covers the platform, this improves the charging compatibility between the antenna and the device 5 being charged, and allows the antenna 3 to be positioned at a higher charging efficiency emission point.

[0045] Specifically, such as Figure 1 and 2 As shown, the track support 22 includes: a first support arm 221 and a second support arm 222; the first support arm 221 is rotatably connected to a first position of the slide rail 23, and the second support arm 222 is rotatably connected to a second position of the slide rail 23 via a first motor 223, the first motor 223 being electrically connected to the control unit; the first position and the second position are located on the same radial axis of the annular structure; the device further includes: a platform 21, the platform 21 being fixedly connected to the first support arm 221 via a connecting shaft 224, the first position of the slide rail 23 passing through the connecting shaft 224; when the slide rail 23 rotates relative to the track support 22, the platform 21 is placed within the annular structure.

[0046] The slide rail 23 can be a two-semi-circular ring structure or at least a complete circular ring structure.

[0047] It should be noted that the annular guide rail 23 passes through the connecting shaft 224 between the first support arm 221 and the platform 21, and does not affect the rotation of the guide rail 23.

[0048] In this embodiment, the first motor 223 is connected to the annular slide rail 23 and drives the slide rail 23 to rotate at least 180° along the extended axis of the first motor 223 so that the slide rail 23 covers a complete spherical surface. The slide rail 23 is equipped with a transmitting antenna 3, which can move and hover along the slide rail 23, thereby realizing that the movement range of the transmitting antenna 3 basically covers the entire spherical surface, which can improve the flexibility of the placement of the device to be charged 5.

[0049] In one embodiment, the slide rail 23 is slidably connected to the track support 22; by moving the slide rail 23 relative to the track support 22, the range of movement of the slide rail 23 covers the platform 21.

[0050] In this embodiment, the slide rail 23 can be a frame structure or a curved structure, such as the two bottom corners of an inverted "U" shape that are slidably connected to the track support 22; or, it can be composed of a frame structure.

[0051] In one embodiment, the track support 22 includes a guide rail structure, and the slide rail 23 is slidably connected to the track support 22 through the guide rail structure; the first state and the second state are two states in which the slide rail 23 is at the beginning end and the end end of the guide rail structure, respectively; wherein, the sliding direction of the antenna 3 along the slide rail 23 is perpendicular to the sliding direction of the slide rail 23 along the guide rail structure.

[0052] In this embodiment, the moving direction of the slide rail 23 is perpendicular to the moving direction of the slider 23 along the slide rail 23. The independent movements of the two perpendicular directions are superimposed to the multi-position movement of the slider 23 in the corresponding plane, thereby realizing the multi-position movement of the transmitting antenna 3 connected to the slider 24, which can improve the flexibility of the placement of the device to be charged 5.

[0053] Specifically, in one embodiment, such as Figures 3 to 6 As shown, the wireless charging device also includes: a platform 21; the track support 22 includes: multiple frame structures 225, the base 1 and the multiple frame structures 225 surround the platform 21 to form a charging space; each frame structure 225 is provided with a guide rail structure, and the guide rail structure is slidably connected to at least one slide rail 23.

[0054] like Figure 3 , 5 The structure shown in Figure 6 is a four-sided frame structure. It can be understood that it can also be a five-sided or six-sided frame structure, and is not limited to this.

[0055] For example, such as Figure 4 The diagram shows an exploded view of a frame structure 225, a slide rail 23, sliders 24, and antennas 3. The track support 2 includes two support rods fixed to one side and has an opening on its inner side as a guide rail structure. The slide rail 23 engages with the opening of the track support 22 and can move back and forth along the opening. In one embodiment, the wireless charging device further includes N sliders 24; wherein the N antennas 3 are connected to the sliders 24, and the sliders 24 are slidably connected to the slide rail 23.

[0056] In this embodiment, the control unit controls the movement of the slide rail 23 and the slider 24 to adjust the transmission position and transmission angle of the antenna 3. The slider 24 and the antenna 3 have a one-to-one correspondence; it can be understood that one slider 24 can connect to multiple antennas 3.

[0057] For example, such as Figure 4 In the middle, there are two support rods on the slide rail 23, and the inner side of the support rods is provided with openings; the slider 24 is connected to the slide rail 23 and can move back and forth along the support rods of the slide rail 23.

[0058] In one embodiment, the slider 24 includes: a slider body 241, a second motor 242, and a friction wheel 243; the slider body 241 is movably connected to the track groove 231 of the slide rail 23; the second motor 242 is fixed on the slider body 241 and rotatably connected to the friction wheel 243; the friction wheel 243 is in contact with the slide rail 23; the second motor 242 is electrically connected to a control unit, and the control unit controls the second motor 242 to rotate, thereby driving the friction wheel 243 to rotate, and the slider 24 moves relative to the slide rail 23.

[0059] For example, such as Figures 7 to 10 As shown, antenna 3 is connected to slider body 21, and slider body 21 has a groove in the middle for connection with guide rail 23. Inside the cavity of slider body 21, friction wheel 243 and friction wheel gear 248 are fitted onto two support columns extending from slider body 21. On the other side, there are two slider motors (second motor 242), each equipped with motor gear 246. Between friction wheel 243 and motor gear 246, there is also a set of intermediate gear 247 and its limiting 251. The slider cover 249 is then connected via two sets of washers 250 of friction wheel gear 248 and motor gear 246.

[0060] Furthermore, in one embodiment, there are two second motors 242 and two friction wheels 243, with one second motor 242 connected to one friction wheel 243; wherein, when the two second motors 242 rotate in opposite directions, the slider 24 stops moving.

[0061] For example, the hidden slider cover 249, the gear state of slider 24 moving and slider 24 hovering is as follows Figure 9 and 10 As shown, the second motor 242 drives the motor gear 246 to rotate, and then transmits the rotation to the friction wheel gear 248 through the intermediate gear 247. The friction wheel gear 248 then drives the friction wheel 243 to act on the slide rail 23. When both sets of second motors 242 rotate in the same direction, they drive the friction wheel 243 to rotate in the same direction through the gear set. Due to the friction between the friction wheel 243 and the slide rail 23, the slider 24 and the antenna 3 move along the slide rail 23. Figure 9 As indicated by the middle arrow, when the two sets of second motors 242 rotate in opposite directions, they drive the friction wheel 243 to rotate in the opposite direction via the gear set. Due to the friction between the friction wheel 243 and the slide rail 23, the slider 24 and the antenna 3 are suspended in a specific position, such as... Figure 10 As indicated by the middle arrow.

[0062] In one embodiment, the antenna 3 includes: an antenna body 31, a rotating bracket 32, and an antenna support 33; the antenna body 31 is fixedly connected to the antenna support 33, the antenna support 33 is rotatably connected to the rotating bracket 32, and the rotating bracket 32 ​​is rotatably connected to the slider 24.

[0063] In this embodiment, the antenna bracket 33 is rotatably connected to the rotating bracket 32, and the rotating bracket 32 ​​is rotatably connected to the slider 24. This allows the antenna to rotate at multiple angles by superimposing two independent rotation angles, thereby increasing the flexibility of the antenna's movement.

[0064] In one specific embodiment, see Figure 11 The slider 24 is provided with a slot, and the rotating bracket 32 ​​is placed in the slot. The rotating bracket 32 ​​is a quadrilateral ring structure. Two opposite corners of the rotating bracket 32 ​​are connected to the slider 24 through a first rotating structure. The other two opposite corners of the rotating bracket 32 ​​are connected to the antenna bracket 33 through a second rotating structure. A first magnetic block 321 and a second magnetic block 322 are respectively provided on two adjacent sides of the rotating bracket 32. The slider 24 is provided with a first coil 244 at a position relative to the first magnetic block 321 and a second coil 245 at a position relative to the second magnetic block 322. The first coil 244 and the second coil 245 are electrically connected to the control unit.

[0065] In this embodiment, the control unit controls two sets of orthogonal coils and magnets to drive the rotating bracket 32 ​​and the antenna bracket 33 to rotate through the first rotating structure and the second rotating structure, respectively. There are two of each of the first and second rotating structures, and they are arranged on different diagonals. In this way, the antenna can be rotated at multiple angles by rotating around two independent diagonals, thereby increasing the flexibility of the antenna's movement.

[0066] In one specific embodiment, the first rotating structure includes: a first spring piece 323 and a first ball bearing 324; the first spring piece 323 is fixedly connected to the antenna bracket 33, and the first spring piece 323 is rotatably connected to the slider 24 through the first ball bearing 324; the second rotating structure includes: a second spring piece 325 and a second ball bearing 326; the second spring piece 325 is fixedly connected to the rotating bracket 32, and the second spring piece 325 is rotatably connected to the antenna bracket 33 through the second ball bearing 326.

[0067] For example, such as Figure 12 As shown, it is a cross-sectional schematic diagram of slider 24 along A-A' and B to B'. Slider 24 is connected to slide rail 23. Slider 24 has a slot on the side closer to the inside of the device to accommodate rotating bracket 32. Rotating bracket 32 ​​is square ring-shaped. Spring pieces are installed at the four corners of rotating bracket 32. Two diagonally opposite first spring pieces 323 are connected to antenna bracket 33 through first ball bearings 324 (including two ball bearings at diagonal positions). The other two diagonally opposite second spring pieces 325 are connected to slider 23 through second ball bearings 326 (including two ball bearings at diagonal positions).

[0068] In one embodiment, a position detection unit is provided on the platform 21; the position detection unit is used to detect the placement position of the device 5 to be charged, and the position detection unit is communicatively connected to the control unit.

[0069] See Figure 2 and Figure 6 As shown, placing a mobile phone, earphones, or other charging devices 5 into the wireless charging device activates the wireless charging mode. The position detection unit within the wireless charging device feeds back the position information of each device 5 to the control unit. The control unit moves the transmitting antennas closer to each device 5 by moving the slide rail 23 and the slider 24 on the slide rail 23. N transmitting antennas will attempt to pair with each device 5. Among the successfully paired combinations, the control unit selects the antenna combination with the highest energy transmission efficiency to charge the device 5.

[0070] It should be pointed out that, Figure 2In the scenario shown, both transmitting antennas 3 are on the same side of the platform 21. Similarly, depending on the placement of the device 5 to be charged, the transmitting antennas 3 can be moved to either side of the platform 21 to improve the energy transfer efficiency between the transmitting antennas 3 and the receiving antennas of the device 5 to be charged. In this way, the placement of the mobile terminal can be minimized while ensuring efficient energy transfer.

[0071] The stage 21 is made of non-metallic material to avoid affecting the antenna's energy transmission.

[0072] In one embodiment, the device further includes a housing 4 disposed on the outer side, the housing 4 having an opening and a receiving cavity.

[0073] In this embodiment, the opening is used to insert and remove the device 5 to be charged, and the receiving cavity formed by the housing 4 can protect the antenna structure and reduce the impact of antenna radiation on the human body.

[0074] In one embodiment, the wireless charging device further includes a display unit disposed on the base 1, the display unit being used to display charging status information of the device 5 to be charged.

[0075] In this embodiment, the charging status information includes at least one of the following: whether the device to be charged has been successfully paired with the target antenna, the charging status of the device to be charged 5 (including whether it is in a charging state, the current charging amount, etc.), and abnormal information of the device to be charged 5 or the wireless charging device.

[0076] In one embodiment, the wireless charging device is also equipped with a fan inside, which can dissipate the heat generated by the antenna.

[0077] As an optional implementation method, see [link to relevant documentation]. Figure 13 The wireless charging device also includes a rectifier and filter circuit 102, a high-frequency conversion circuit 103, and a power amplifier circuit 104. The rectifier and filter circuit 102 is electrically connected to a power source, and is sequentially electrically connected to the antenna through the high-frequency conversion circuit 103 and the power amplifier circuit 104. Thus, the rectifier and filter circuit 102, the high-frequency conversion circuit 103, and the power amplifier circuit 104 facilitate current conversion within the wireless charging device. Furthermore, the current transmission performance is enhanced after passing through the power amplifier circuit 104, resulting in higher charging efficiency for the device 5 and thus saving charging time.

[0078] The device to be charged 5 may include a receiving antenna 501, a rectifier-converter circuit 502, and a load 503. The receiving antenna 501 can receive the energy emitted by the antenna and convert the energy into electrical energy through the rectifier-converter circuit 502, which then flows to the load 503. The load 503 can be referred to as a battery, thereby achieving the effect of wirelessly charging the battery of the device to be charged 5.

[0079] The following is in conjunction with the appendix Figure 14 and 15 The wireless charging process will be explained.

[0080] As an example, such as Figure 14 In it, it shows as follows Figure 6 The schematic diagram of the charging process of the wireless charging device shown mainly includes the following steps:

[0095] Step 2: The location detection unit detects the location information of the mobile terminal and feeds it back to the control unit.

[0096] Step 3: The control unit moves the transmitting antenna to a position close to the mobile terminal by controlling the rotation of the annular guide rail (slide rail 23) and the movement of the slider on the annular guide rail.

[0097] Step 4: The control unit controls the antennas to pair with the mobile terminals one by one.

[0098] Step 5: The control unit monitors whether each antenna and each mobile terminal are successfully paired, and tests the charging efficiency data of the successfully paired scenario.

[0099] Step 6: Determine if the pairing is successful; if yes, proceed to step 7; otherwise, proceed to step 10.

[0100] Step 7: In the successfully paired combinations, the control unit selects the successfully paired and efficient antennas to charge each mobile terminal and displays the charging status information of each mobile terminal.

[0101] Step 8: Determine if the user has adjusted the position or orientation of the mobile terminal; if yes, proceed to step 2; if no, proceed to step 9.

[0102] Step 9: Continue charging until completion, and display the charging status information of each mobile terminal.
