Description

Technical Field

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

[0002] Typically, a ring magnet can be placed in a wireless charging device. When a user needs to wirelessly charge an electronic device, the user can bring the electronic device close to the wireless charging device so that the ring magnet can generate a magnetic attraction between the electronic device and the electronic device, thereby allowing the electronic device to be firmly fixed to the wireless charging device by the magnetic attraction.

[0003] However, since the magnetic attraction between the ring magnet and the electronic device may be strong, users may need to use a lot of force to separate the electronic device from the wireless charging device when they need to remove it.

[0004] Therefore, wireless charging devices are not very convenient to use. Summary of the Invention

[0005] The purpose of this application is to provide a wireless charging device that can solve the problem of poor ease of use of wireless charging devices.

[0006] In a first aspect, embodiments of this application provide a wireless charging device, comprising: a base, the base including a support surface for placing an electronic device to be charged; a charging coil disposed within the base for charging the electronic device placed on the base; a magnetic component movably disposed within the base for magnetically attracting the electronic device placed on the base, the magnetic component having an inclined surface on one side; a cam component rotatably disposed within the base, one end of the cam component abutting against the inclined surface; and a pressing component, at least a portion of the pressing component protruding from one side of the base, the pressing component being convexly connected to the cam component; wherein, when the pressing component is pressed, the pressing component drives the cam component to rotate, the cam component driving the magnetic component to move away from the support surface.

[0007] In this embodiment, the wireless charging device includes a base (the base includes a support surface for placing an electronic device to be charged), a charging coil disposed within the base for charging the electronic device placed on the base, a magnetic component movably disposed within the base (the magnetic component has an inclined surface on one side), a cam component rotatably disposed within the base (one end of the cam component abuts against the inclined surface), and a pressing component (at least part of the pressing component protrudes from one side of the base) that is drively connected to the cam component; wherein, when the pressing component is pressed, the pressing component drives the cam component to rotate, and the cam component drives the magnetic component to move away from the support surface. When the pressing component is pressed, it can drive the cam component to rotate, so that the cam component can drive the magnetic component to move away from the support surface through the inclined plane. This increases the distance between the magnetic component and the electronic device to be charged, thereby reducing the magnetic attraction between them. Therefore, when the user needs to remove the electronic device from the wireless charging device, the user can separate it from the wireless charging device with less force, thus improving the ease of use of the wireless charging device.

[0026] To address this technical problem, the embodiments of this application employ the following technical solutions.

[0027] Figure 1 This application provides a possible structural schematic diagram of a wireless charging device according to an embodiment of the present application, such as... Figure 1 As shown, the wireless charging device includes: a base 10, which includes a support surface 101 for placing an electronic device to be charged; a charging coil 11 disposed within the base 10 for charging the electronic device placed on the base 10; a magnetic component 12 movably disposed within the base 10 for magnetically attracting the electronic device placed on the base 10, wherein one side of the magnetic component 12 is provided with an inclined surface 13; a cam component 14 rotatably disposed within the base 10, wherein one end of the cam component 14 abuts against the inclined surface 13; and a pressing component 15, at least a portion of which protrudes from one side of the base 10, and is kinetically connected to the cam component 14.

[0028] Optionally, in the embodiments of this application, the wireless charging device can be any of the following: an in-vehicle wireless charging device, a fixed wireless charging device, etc.

[0029] Optionally, in this embodiment of the application, the magnetic component 12 is arranged around the charging coil 11.

[0030] It is understood that the wireless charging device can use the magnetic attraction of the magnetic component 12 to fix the electronic device to be charged onto the support surface 101.

[0031] Optionally, in this embodiment, the electronic device to be charged is provided with a first magnetic component. When the electronic device is placed on the support surface 101, a magnetic attraction force can be generated between the first magnetic component and the magnetic component 12 to fix the electronic device to the support surface 101. The first magnetic component can be any of the following: a metal with a primary magnet structure (e.g., iron, nickel, cobalt, some alloys, etc.), a permanent magnet (e.g., a magnet, a lodestone, etc.), an electromagnet, etc.

[0032] Optionally, in this embodiment, the base 10 of the wireless charging device may further include a mounting surface (e.g., the target surface in the following embodiment), which is used to mount the magnetic component 12 and the cam component 14.

[0033] In this embodiment of the application, the magnetic component 12 is used to generate a magnetic attraction force to attract the electronic device to be charged.

[0034] Optionally, in this embodiment, the magnetic component 12 can be fixed to the mounting surface (e.g., the target surface in the following embodiment) by means of an elastic element (e.g., a spring).

[0035] Optionally, in the embodiments of this application, the magnetic component 12 may be one magnetic component or multiple magnetic components.

[0036] Optionally, in the embodiments of this application, the magnetic component 12 can be any of the following: a metal (e.g., iron, nickel, cobalt, some alloys, etc.) with a primary magnet structure, a permanent magnet (e.g., a magnet, a lodestone, etc.), an electromagnet, etc.

[0037] Optionally, in the embodiments of this application, when the magnetic component 12 includes a magnetic component, the shape of the magnetic component 12 can be any of the following: ring, triangle, rectangle, polygon, irregular shape, etc.

[0038] Optionally, in this embodiment, a chamfer can be provided at the end of the inner side of the magnetic component 12 to form a bevel 13.

[0039] The inclined plane 13 may include one or more inclined planes. When the inclined plane 13 includes one inclined plane, the inclined plane 13 may be an annular inclined plane; when the inclined plane 13 includes multiple inclined planes, the inclined plane 13 may include multiple inclined plane portions that are symmetrical about the center of rotation of the transmission structure.

[0040] Alternatively, in this embodiment, the inclined surface 13 may include a first inclined surface portion and a second inclined surface portion, the first inclined surface portion and the second inclined surface portion being symmetrical about the rotation axis of the transmission structure.

[0041] Optionally, in this embodiment of the application, the magnetic component 12 is ring-shaped, and the first inclined portion and the second inclined portion are both disposed on the end of the side of the magnetic component 12 close to the center of the ring.

[0042] For example, Figure 2 A cross-sectional schematic diagram of the magnetic component 12 according to an embodiment of this application is shown. Figure 2 As shown, the magnetic component 12 includes a magnetic component, and a chamfer can be provided at the top end of the inner side of the magnetic component 12 to form a slope. The slope includes a first slope portion 131 and a second slope portion 132, which are symmetrical about the rotation axis of the transmission structure.

[0043] Optionally, in the embodiments of this application, when the magnetic component 12 includes multiple magnetic components, the shape of the magnetic component 12 can specifically be an arc shape.

[0044] Optionally, in this embodiment of the application, the magnetic component 12 includes: a first magnetic component, on which a first inclined portion is provided on the side of the first magnetic component close to the cam component 14; and a second magnetic component, on which a second inclined portion is provided on the side of the second magnetic component close to the cam component 14.

[0045] For example, Figure 3 A cross-sectional schematic diagram of the magnetic component 12 according to an embodiment of this application is shown. Figure 3 As shown, the magnetic assembly includes a first magnetic assembly 121 and a second magnetic assembly 122. A chamfer is provided at the top end of the side of the first magnetic assembly 121 that is close to the cam assembly 14 to form a first inclined portion 131. A chamfer is provided at the top end of the side of the second magnetic assembly 122 that is close to the cam assembly 14 to form a second inclined portion 132.

[0046] In this embodiment, the cam assembly 14 is used to drive the magnetic assembly 12 to move away from the support surface 101 via the inclined plane 13.

[0047] Optionally, in this embodiment, at least a portion of the cam assembly 14 may be disposed on a mounting surface (e.g., the target surface in the embodiments below).

[0048] Optionally, in this embodiment of the application, the moving end of the cam assembly 14 may abut against the inclined surface 13.

[0049] Optionally, in this embodiment of the application, the cam assembly 14 can be driven by the pressing assembly 15.

[0050] In the case where the cam assembly 14 is driven by the pressing assembly 15, the pressing assembly 15 may include a plurality of transmission components. One of the transmission components abuts against the inclined surface 13, and the other transmission components (i.e., the transmission components other than the one transmission component) abut against each other. Thus, when the user presses the pressing assembly 15, the other transmission components can drive the one transmission component to move in the direction toward the inclined surface 13, so that the elastic element is in an elastic deformation state, thereby causing the magnetic assembly 12 to move in the direction away from the support surface 101.

[0051] Optionally, in this embodiment of the application, when the electronic device to be charged is fixed on the support surface 101, if the user wants to remove the electronic device from the support surface 101, the user can press the pressing component 15 to drive the cam component 14, so that the cam component 14 drives the magnetic component 12 to move away from the support surface 101 through the inclined surface 13, thereby increasing the distance between the magnetic component 12 and the support surface 101, and increasing the distance between the magnetic component 12 and the electronic device to be charged, thereby reducing the magnetic attraction between the magnetic component 12 and the electronic device to be charged.

[0052] The wireless charging device provided in this application includes a base (the base includes a support surface for placing an electronic device to be charged), a charging coil disposed in the base for charging the electronic device placed in the base, a magnetic component movably disposed in the base (the magnetic component has an inclined surface on one side), a cam component rotatably disposed in the base (one end of the cam component abuts against the inclined surface), and a pressing component (at least part of the pressing component protrudes from one side of the base) that is drively connected to the cam component; wherein, when the pressing component is pressed, the pressing component drives the cam component to rotate, and the cam component drives the magnetic component to move away from the support surface. When the pressing component is pressed, it can drive the cam component to rotate, so that the cam component can drive the magnetic component to move away from the support surface through the inclined plane. This increases the distance between the magnetic component and the electronic device to be charged, thereby reducing the magnetic attraction between them. Therefore, when the user needs to remove the electronic device from the wireless charging device, the user can separate it from the wireless charging device with less force, thus improving the ease of use of the wireless charging device.

[0053] The specific structure of the cam assembly 14 is illustrated below with an example.

[0054] Optionally, in the embodiments of this application, combined with Figure 1 ,like Figure 4 As shown, the cam assembly 14 includes: an eccentric cam 16, which is rotatably disposed in the base 10, with its first end abutting against an inclined surface 13, which extends obliquely toward the eccentric cam 16; and a transmission structure 17, which abuts against the second end of the eccentric cam 16.

[0055] It is understood that the aforementioned eccentric cam 16 can rotate in a direction parallel to the target surface (i.e., parallel to the support surface 101). The first end of the eccentric cam 16 abuts against the inclined surface 13, and the second end of the eccentric cam 16 is connected to the transmission structure 17.

[0056] Alternatively, in this embodiment of the application, the number of the aforementioned eccentric cams 16 may be at least two.

[0057] Alternatively, in this embodiment of the application, the eccentric cam 16 can be movably riveted to the target surface.

[0058] In this embodiment of the application, the transmission structure 17 is used to drive the eccentric cam 16 to rotate in a first direction, thereby causing the eccentric cam to drive the magnetic component 12 to move in a direction away from the support 101 through the inclined surface; the first direction is parallel to the support surface 101.

[0059] Further optionally, in this embodiment of the application, one end of the transmission structure 17 can be disposed through the base 10, and the other end of the transmission structure 17 can abut against the eccentric cam 16, so that the transmission structure 17 can drive the eccentric cam 16 to rotate in the same direction, so that one end of the eccentric cam 16 can move in the direction toward the inclined plane 13, so as to drive the magnetic component 12 to move away from the support surface 101 through the inclined plane 13.

[0060] In this embodiment of the application, when the pressing component 15 is pressed, the pressing component 15 drives the eccentric cam 16 to rotate through the transmission structure 17, and the eccentric cam 16 drives the magnetic component 12 to move in a direction away from the support surface 101.

[0061] Thus, it can be seen that since the transmission structure in the cam assembly can drive the eccentric cam to rotate, thereby driving the magnetic assembly to move in a direction away from the support surface, the stability of the magnetic assembly's movement can be improved.

[0062] The following example illustrates the concept of two eccentric cams and a ring-shaped magnetic component 12.

[0063] Optionally, in the embodiments of this application, combined with Figure 4 ,like Figure 5As shown, the aforementioned eccentric cam includes: a first eccentric cam 161, the first end of which abuts against the first inclined surface portion 131, and the second end of which abuts against the transmission structure 17; and a second eccentric cam 162, the first end of which abuts against the second inclined surface portion 132, and the second end of which abuts against the transmission structure 17.

[0064] In this embodiment, the first eccentric cam 161 and the second eccentric cam 162 are symmetrical about the rotation axis of the transmission structure 17.

[0065] Further optionally, in this embodiment of the application, the first eccentric cam 161 can be movably riveted to the target surface; the second eccentric cam 162 can be movably riveted to the target surface.

[0066] Alternatively, in the embodiments of this application, the first eccentric cam 161 and the second eccentric cam 162 may have the same shape.

[0067] In this embodiment of the application, combined with Figure 5 The transmission structure 17 can drive the first eccentric cam 161 and the second eccentric cam 162 to rotate in a first direction (e.g., clockwise), so that the first end of the first eccentric cam 161 can move toward the first inclined surface portion 131, and the first end of the second eccentric cam 162 can move toward the second inclined surface portion 132, so as to drive the magnetic component 12 to move away from the support surface 101 through the first inclined surface portion 131 and the second inclined surface portion 132.

[0068] Thus, since the first and second eccentric cams are symmetrical about the axis of rotation of the transmission structure, and the wireless charging device can drive the first and second eccentric cams to rotate through the transmission structure without the need for additional eccentric cams, it can stably drive the magnetic components to move away from the support surface while saving costs.

[0069] Of course, when the pressing component 15 is stopped from being pressed, the first eccentric cam 161 and the second eccentric cam 162 can be restored to their original positions by the elastic component.

[0070] Optionally, in this embodiment of the application, the wireless charging device further includes: a first elastic component disposed between the first eccentric cam 161 and the target surface, the target surface being a support surface or a surface opposite to the support surface; and a second elastic component disposed between the second eccentric cam 162 and the target surface, the target surface being a support surface or a surface opposite to the support surface.

[0071] For example, such as Figure 6As shown, the first elastic component 18 is disposed between the first eccentric cam 161 and the support surface 101; the second elastic component 19 is disposed between the second eccentric cam 162 and the support surface 101.

[0072] Further optionally, in the embodiments of this application, the first elastic component 18 and the second elastic component 19 can be coil springs.

[0073] Alternatively, in the embodiments of this application, the spring structures of the first elastic member 18 and the second elastic member 19 may be the same.

[0074] Alternatively, in this embodiment of the application, the two ends of the first elastic member 18 can be fixedly connected to the first eccentric cam 161 and the target surface, respectively.

[0075] Alternatively, in this embodiment of the application, both ends of the second elastic member 19 can be fixedly connected to the target surface by the second eccentric cam 162, respectively.

[0076] It is understood that when the pressing component 15 is pressed, the transmission structure 17 drives the first eccentric cam 161 and the second eccentric cam 162 to rotate. At this time, the first elastic component 18 and the second elastic component 19 are twisted and in an elastic deformation state. When the pressing component 15 is stopped, the first elastic component 18 and the second elastic component 19 drive the first eccentric cam 161 and the second eccentric cam 162 to rotate back to their original positions during the process of restoring their elastic deformation, so as to perform the next pressing action.

[0077] Thus, since the first and second elastic components can repeatedly undergo elastic deformation, the first and second eccentric cams can rotate repeatedly. Therefore, the magnetic components can be stably driven to move away from the support surface while saving costs.

[0078] The following will provide examples illustrating the specific structure of the transmission mechanism.

[0079] Optionally, in this embodiment of the application, the first end of the transmission structure 17 abuts against the second end of the first eccentric cam 161, and the second end of the transmission structure 17 abuts against the second end of the second eccentric cam 162.

[0080] Further optionally, in this embodiment of the application, the transmission structure 17 can specifically be a rotating block; wherein, the rotating block can be disposed on the target surface through a central rotating shaft, and can rotate in a direction parallel to the target surface.

[0081] Specifically, the central rotating shaft can be set on the target surface by a coil spring, so that after the transmission structure 17 rotates in the second direction to drive the eccentric cam 16 to rotate in the first direction, the transmission structure 17 can rotate in the first direction under the action of the restoring force of the coil spring to drive the eccentric cam 16 to rotate in the second direction, so that the magnetic component 12 can move in the direction toward the support surface 101.

[0082] Further optionally, in the embodiments of this application, the transmission structure 17 may include at least one moving end, and the first side of each moving end abuts against the second end of an eccentric cam 16.

[0083] The following will use the transmission structure 17, which includes two moving ends, as an example to illustrate the structure in the cam assembly 14.

[0084] Optionally, in the embodiments of this application, combined with Figure 3 ,like Figure 7 As shown, the cam assembly further includes: a first rotating lever 141, the first end of which abuts against the first end of the transmission structure 17, and the second end of which abuts against the first end of the pressing assembly 15; and a second rotating lever 142, the first end of which abuts against the second end of the transmission structure 17, and the second end of which abuts against the second end of the pressing assembly 15.

[0085] Optionally, in the embodiments of this application, combined with Figure 7 ,like Figure 8 As shown, the moving end of the transmission structure 17 includes a first moving end 20 and a second moving end 21. The first side of the first moving end 20 abuts against the second end of the first eccentric cam 161, and the first side of the second moving end 21 abuts against the second end of the second eccentric cam 162. The first end of the first rotating lever 141 abuts against the second side of the first moving end 20; the first end of the second rotating lever 142 abuts against the second side of the second moving end 21.

[0086] In this embodiment of the application, the first rotating lever 141 and the second rotating lever 142 are symmetrical about the rotation axis of the transmission structure.

[0087] In this embodiment of the application, combined with Figure 8When the pressing component 15 is pressed, it can drive the first rotating lever 141 to rotate in a first direction (e.g., clockwise) and drive the second rotating lever 142 to rotate in a clockwise direction. Thus, the first rotating lever 141 can apply a rightward force to the second side of the first moving end 20, and the second rotating lever 142 can apply a leftward force to the second moving end 21, causing the transmission structure 17 to rotate counterclockwise. This allows the first side of the first moving end 20 to drive the first eccentric cam 161 to rotate clockwise, and the first side of the second moving end 21 to drive the second eccentric cam 162 to rotate clockwise. At this time, the end of the first eccentric cam 161 near the magnetic component 12 can move towards the inclined plane 13, and the end of the second eccentric cam 162 near the magnetic component 12 can move towards the inclined plane 13. Figure 9 As shown, after the end of the first eccentric cam 161 near the magnetic component 12 moves in the direction toward the inclined plane 13, and the end of the second eccentric cam 162 near the magnetic component 12 moves in the direction toward the inclined plane 13, the ends of the first eccentric cam 161 and the ends of the second eccentric cam 162 near the magnetic component 12 can drive the magnetic component 12 to move in the direction away from the support surface.

[0088] Thus, since the first and second rotating levers are symmetrical about the axis of rotation of the transmission structure, and the transmission structure can drive the first and second rotating levers to rotate through the first and second moving ends respectively, the magnetic component can be stably driven to move away from the support surface.

[0089] Optionally, in the embodiments of this application, combined with Figure 1 ,like Figure 10 As shown, the pressing assembly includes: a pressing part 151 protruding from one side of the base 10; and a push rod 152, the first end of which is connected to the pressing part 151, and the second end of which passes through one side of the base 10 and abuts against the cam assembly 14.

[0090] Optionally, in this embodiment of the application, the pressing component 15 may include at least one pressing part 151 and a push rod 152.

[0091] Alternatively, in the embodiments of this application, at least one pressing part 151 may have the same shape.

[0092] Alternatively, in this embodiment, the push rod 152 may specifically be a set of push rods.

[0093] Further optionally, in this embodiment of the application, the first ends of two of the push rods in the set of push rods can be connected to the pressing part 151, the second end of one of the push rods in the set of push rods passes through one side of the base 10 and abuts against the first end of the first rotating lever 141 in the cam assembly 14, and the second end of the other push rod in the set of push rods passes through one side of the base 10 and abuts against the second end of the second rotating lever 142 in the cam assembly 14.

[0094] Alternatively, in the embodiments of this application, each pressing part 151 corresponds to a set of push rods.

[0095] The following example illustrates the process using a pressing component consisting of two pressing parts.

[0096] Optionally, in the embodiments of this application, combined with Figure 10 ,like Figure 11 As shown, the pressing assembly includes: a first pressing part 1511, which is disposed on the first side of the device body 10; a set of push rods corresponding to the first pressing part 1511, including a first push rod 1521 and a second push rod 1522; the first end of the first push rod 1521 and the first end of the second push rod 1522 are respectively connected to the first pressing part 1511; the second end of the first push rod 1521 passes through the first side of the base and abuts against the second end of the first rotating lever 141; the second end of the second push rod 1522 passes through the first side of the base and abuts against the first end of the second rotating lever 142. Abutting; a second pressing part 1512, which is disposed on the second side of the device body 10, and a set of push rods corresponding to the second pressing part 1512, including a third push rod 1523 and a fourth push rod 1524. The first end of the third push rod 1523 and the first end of the fourth push rod 1524 are respectively connected to the second pressing part 1512; the second end of the third push rod 1523 passes through the second side of the base 10 and abuts against the second end of the first rotating lever 141, and the second end of the fourth push rod 1524 passes through the second side of the base 10 and abuts against the first end of the second rotating lever 142.

[0097] In this embodiment, the first push rod 1521 and the fourth push rod 1524 are parallel, and the second push rod 1522 and the third push rod 1523 are parallel.

[0098] In this embodiment of the application, both the first side and the second side are adjacent to the target surface, and the first side is opposite to the second side; when the first pressing part 1511 and the second pressing part 1512 are pressed, the push rod corresponding to the first pressing part 1511 moves along a third direction, and the push rod corresponding to the second pressing part 1512 moves along a fourth direction, so as to drive the first rotating lever 141 and the second rotating lever 142 to rotate along the first direction; the third and fourth directions are both parallel to the support surface 101, and the third and fourth directions are opposite.

[0099] Thus, since the first pressing part and the second pressing part can be disposed on different sides of the device base that are adjacent to and opposite to the target surface, when the electronic device to be charged is fixed on the support surface, the user can conveniently press the first pressing part and the second pressing part at the same time to drive the magnetic component to move away from the support surface.

[0100] Optionally, in the embodiments of this application, the first pressing part 1511 and the second pressing part 1512 are symmetrical about the center of the target surface.

[0101] Thus, it can be seen that since the first pressing part and the second pressing part can be symmetrically set at different positions at the center of the target surface, the stability of the movement of the magnetic component can be improved.

[0102] Of course, when the pressing component 15 is stopped from being pressed, the magnetic component 12 needs to be reset so that the next pressing operation can be performed normally.

[0103] Optionally, in this embodiment of the application, the wireless charging device further includes: a third elastic component, the first end of which is connected to the target surface, and the second end of which is connected to the magnetic component 12.

[0104] For example, combined with Figure 1 ,like Figure 12 As shown, the first end of the third elastic component 22 is connected to the support surface 101, and the second end of the third elastic component 22 is connected to the magnetic component 12.

[0105] Alternatively, in this embodiment, the third elastic component 22 may be a spring.

[0106] In this embodiment of the application, when the cam assembly 14 drives the magnetic assembly 12 to move in a direction away from the support surface 101, the third elastic component 22 is in an elastic compression state.

[0107] When the pressing component 15 is stopped, the third elastic component 22 drives the magnetic component 12 to move toward the support surface 101 during the process of restoring elastic deformation.

[0108] Thus, since the third elastic component can repeatedly undergo elastic deformation, the magnetic component can reciprocate. Therefore, it is possible to stably drive the magnetic component to move in a direction away from the support surface while saving costs.
