[0046] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0047] Figure 1 The circuit design of the connection structure 1 according to the embodiment of the utility model is shown below. Figure 1 The connection structure 1 will be described.
[0048] The connection structure 1 is arranged in an electronic product or a charging device, wherein the electronic product has a charging interface, the charging device has a connection socket, and the connection structure is arranged to keep the charging interface of the electronic product and the connection socket of the charging device connected. When the electronic product is charged by the charging device, the electronic product and the charging device can be kept stably connected to prevent the charging interface and the connection socket from being in an unstable contact, or the electronic product from falling off the charging device. Preferably, an iron core is also arranged inside the coil 10 to increase the magnitude of the magnetic force generated by the coil 10 after power is supplied.
[0049] In this embodiment, the connection structure 1 includes a coil 10 and a controller 20. The controller 20 is electrically connected to the coil 10 and is configured to control the power on and off of the coil 10. The way in which the controller 20 controls the power on and off of the coil 10 includes, for example, directly setting an on-off switch between the coil 10 and the power supply. It can also be implemented in other forms, which will be specifically described in subsequent embodiments.
[0050] According to different embodiments of the utility model, the coil 10 can be arranged in an electronic product or in a charging device. For example, the coil 10 is arranged in an electronic product and is close to the outer shell of the electronic product. A magnetic component 2 is arranged in the charging device, and after the coil 10 is powered on, it attracts the magnetic component 2 in the charging device. Under the action of the coil 10 and the magnetic component 2, the electronic product is fixed on the charging device. In this embodiment, the user-operable components in the controller 20 can be arranged on the surface of the electronic product for user operation, and the on and off of the coil 10 can be controlled according to the user control instruction, thereby changing the attraction between the electronic product and the charging device.
[0051] Preferably, when the coil 10 is disposed in an electronic product, a magnetic field shielding structure may also be disposed in the electronic product, for example, a magnetic yoke made of soft magnetic material may be disposed on the outside of the coil 10, which can both increase the attraction between the coil 10 and the magnetic component 2 and reduce the impact of the magnetic field of the coil 10 on the electronic product.
[0052] In other embodiments of the present invention, the coil 10 is disposed inside the charging device and close to the housing of the charging device, a magnetic component 2 is disposed inside the electronic product, and when the coil 10 is energized, the coil 10 and the magnetic component 2 inside the electronic product attract each other. The user-operable components of the controller 20 are disposed on the surface of the charging device.
[0053] When the coil 10 is disposed in an electronic product, it can be powered by a battery of the electronic product, or an independent power source can be provided for the coil 10. When the coil 10 is disposed in a charging device, the coil 10 can be connected to a power source of the charging device and powered by the charging device.
[0054] The magnetic component 2 includes one or more of a permanent magnet, a magnetic metal part and an electromagnet, and is fixedly arranged inside one of the charging device and the electronic product, and the coil 10 is arranged inside the other of the two. When the magnetic component 2 is a permanent magnet, the polarity of the permanent magnet is opposite to the polarity of the magnetic field generated by the coil 10. Preferably, the magnetic component 2 is a structure made of magnetic metal, which will not absorb small particles of metal, and can prevent metal from entering the interior of the charging device or the electronic product during normal use or placement, thereby avoiding line failure.
[0055] The embodiment of the utility model can realize the electronic product being taken out from the charging device with one hand, thus simplifying the user's operation. Meanwhile, the attraction between the coil 10 and the magnetic component 2 can also keep the electronic product connected to the charging device during the charging process, thus improving stability.
[0056] According to a preferred embodiment of the present utility model, Figure 1As shown, the controller 20 includes a switch 21 and a microcontroller unit 22, wherein the switch 21 is arranged on the surface of the electronic product or the charging device, preferably on the electronic product, at a surface position that can be directly touched by the user when picking up the electronic product, such as the side edge of the electronic product.
[0057] The switch 21 can receive a user control instruction and output an opening signal or a closing signal according to the user control instruction. When the user picks up the electronic product, the user can input the user control instruction through the switch 21, and the electrical connection structure relationship or the preset rule of the switch 21 can output the opening signal or the closing signal according to the user's control instruction. Specifically, for example, the switch 21 includes a physical button, and the user changes the electrical connection relationship of the switch 21 by pressing the physical button, thereby outputting the opening signal or the closing signal.
[0058] According to a preferred embodiment of the present utility model, Figure 2 As shown, the switch 21 may further include a touch sensing module 23, which is disposed on the surface of the electronic product or the charging device, preferably on the surface of the electronic product, for user operation. The touch sensing module 23 can receive user control instructions, for example, the touch sensing module 23 can output an opening signal and a closing signal according to the capacitance or resistance change generated when the user's finger approaches or presses the touch sensing module 23, further simplifying the user's operation process.
[0059] Further, such as Figure 1 and Figure 2 As shown, in a preferred embodiment of the utility model, the micro control unit 22 is arranged between the coil 10 and the switch 21, and the micro control unit 22 is arranged to receive the opening signal and the closing signal of the switch 21, and control the power-off and power-on of the coil 10 according to the opening signal and the closing signal of the switch 21, for example, control the voltage at both ends of the coil 10. Specifically, the micro control unit 22 can be an integrated circuit or a single chip microcomputer, and can be integrated with other circuit components inside the electronic product or the charging device.
[0060] like Figure 3 As shown, in a preferred embodiment of the present utility model, the shapes of the charging interface 111 in the electronic product 100 and the connection seat 211 in the charging device 200 match each other. For example, the connection seat 211 is a raised table shape, and the charging interface 111 can be set to a groove shape, and the groove shape and the shape of the connection seat 211 match each other, so that the connection seat 211 can be inserted into the charging interface 111. The charging interface 111 and the connection seat 211 can also be other shapes, and the charging interface 111 is preferably a concave shape to keep the shape of the electronic product 100 uniform.
[0061] In this embodiment, the charging interface 111 and the connection base 211 both have a centrally symmetrical shape, and the coil 10 and the magnetic component 2 are both symmetrically arranged relative to the symmetry center of the charging interface 111 and the connection base 211. For example, the cross-sectional shape of the charging interface 111 and the connection base 211 perpendicular to the plug-in and unplug directions is a circle, the symmetry center is the center of the circle, and the coil 10 and the magnetic component 2 are symmetrically arranged relative to the center of the circle. Or as Figure 3 As shown, the charging interface 111 and the connecting seat 211 are both circumferentially processed into rounded tetrahedrons, the center of symmetry is the shape center of the tetrahedron, and the coil 10 and the magnetic component 2 are symmetrically arranged relative to the shape center of the tetrahedron.
[0062] Furthermore, the contacts in the charging interface 111 and the connecting socket 211 are also arranged to be centrally symmetrical, and the connection relationship between the electronic product 100 and the charging device 200 is not limited in direction. For example, if the electronic product 100 is flipped 180°, it can still be connected to the charging device 200 and charged normally.
[0063] In a preferred embodiment of the utility model, the connection structure 1 includes two coils 10, and the charging device 200 or the electronic product 100 includes two magnetic components 2 (the magnetic components 2 and the coils 10 are arranged in different structures), and along the connection direction of the charging interface 111 and the connecting seat 211, for example, the plugging and unplugging direction, the positions of the coils 10 and the magnetic components 2 are aligned.
[0064] For example Figure 3 As shown in the figure, the shape of the charging interface 111 and the connecting seat 211 is roughly a quadrangular pyramid with rounded corners in the circumferential direction. Two coils 10 are arranged side by side in the long side direction of the charging interface 111, and the two coils 10 are arranged to be centrally symmetrical. Two magnetic components 2 are arranged side by side in the long side direction of the connecting seat 211, and when the electronic product 100 and the charging device 200 are connected, the coil 10 and the magnetic component 2 are aligned in the connection direction of the charging interface 111 and the connecting seat 211, so that the attraction between the coil 10 and the magnetic component 2 is perpendicular to the connection surface of the electronic product 100 and the charging device 200, which can reduce the internal stress of the electronic product 100 and the charging device 200 and is conducive to improving the structural stability.
[0065] According to a preferred embodiment of the utility model, the connection seat 211 is roughly configured in a prism shape, and the charging interface 111 is roughly configured in a concave prism shape. Furthermore, the edges of the prism shape are processed with chamfers, and curved arc surfaces can also be processed at the upper and lower edges of the connection seat 211. Processing chamfers and arc surfaces can minimize collisions between the electronic product 100 and the charging device 200, and protect the charging device 200 and the electronic product 100.
[0066] like Figure 4As shown, the embodiment of the utility model also includes an electronic product 100, which includes a housing 110, a power board 120 and a connection structure 1 as described in the above embodiment, wherein the connection structure 1 and the power board 120 are both arranged in the housing 110, and the switch 21 in the controller 20 is arranged on the surface of the housing 110. A charging interface 111 is arranged on the housing 110, and the charging interface 111 is electrically connected to the power board 120, and the power board 120 can be powered by the charging interface 111.
[0067] The coil 10 in the connection structure 1 is close to the housing 110 and is arranged near the charging interface 111. Preferably, the axial direction of the coil 10 is parallel to the plug-in and unplugging direction of the charging interface 111 and the charging device 200. When the coil 10 is energized, one pole of the generated magnetic field is close to the housing 110.
[0068] When the electronic product 100 in this embodiment is connected to the charging device 200 for charging, the controller 20 can be configured to energize the coil 10. For details, please refer to the above embodiment. The coil 10 and the magnetic component 2 in the charging device 200 attract each other, so that the electronic product 100 and the charging device 200 remain connected. When charging is completed or the electronic product 100 needs to be removed from the charging device 200, the user can operate the controller 20 to disconnect the coil 10, and the attraction between the coil 10 and the magnetic component 2 disappears or is reduced to a minimum, and the electronic product 100 and the charging device 200 are separated. The user can complete the process of taking the electronic product with one hand, which improves the user's experience and is suitable for situations where it is inconvenient to operate with both hands. There is no need to use the gravity of the charging device 200 itself to separate the electronic product 100 and the charging device 200, which is conducive to simplifying the structure of the charging device 200.
[0069] like Figure 4 As shown, according to a preferred embodiment of the present utility model, the charging interface 111 includes a connection groove 112, and the connection groove 112 is located on the surface of the housing 110. The connection groove 112 is, for example, a groove structure on the housing 110 to keep the overall appearance of the electronic product 100 uniform. The charging device 200 matching the electronic product 100 includes a connection seat 211, and the shape of the connection groove 112 matches the shape of the connection seat 211, and the connection seat 211 can be inserted into the connection groove 112.
[0070] Further, the connection slot 112 is of a centrally symmetrical shape, and the charging interface 111 includes a plurality of first terminals 113 and a second terminal 114, each of the first terminal 113 and the second terminal 114 can be connected to the charging device 200 and form a charging circuit, for example, the level of the first terminal 113 is higher than the level of the second terminal 114, or the level of the second terminal 114 is higher than the level of the first terminal 113. Specifically, the first terminal 113 can be set as a VBus (power line) terminal, and the second terminal 114 can be set as a ground terminal.
[0071] The second terminal 114 is disposed at the symmetrical center of the connection slot 112, and the plurality of first terminals 113 are symmetrically disposed relative to the symmetrical center of the connection slot 112. The connection relationship between the electronic product 100 and the charging device 200 is not limited to a fixed position. For example, the electronic product 100 can be connected to the charging device 200 and can be charged normally after being rotated 180°.
[0072] Specific, for example Figure 4 As shown in , the charging interface 111 includes two first terminals 113, the two first terminals 113 are arranged on both sides of the second terminal 114, and the two first terminals 113 are arranged to be centrally symmetrical relative to the symmetry center of the charging interface 111 (the location of the second terminal 114). In different embodiments of the utility model, the number of first terminals 113 can also be multiple, for example, 4 or more first terminals 113 are arranged, all of which are centrally symmetrically arranged relative to the location of the second terminal 114. According to other embodiments of the utility model, the multiple first terminals 113 can also be arranged in a centrally symmetrical pattern, such as a rectangular or circular conductive sheet, and are arranged symmetrically about the circumference of the second terminal 114.
[0073] like Figure 5 As shown, an embodiment of the utility model also includes a charging device 200 corresponding to the electronic product 100 in the aforementioned embodiment, and the charging device 200 includes a connecting socket 211, and a charging terminal 212 is arranged on the connecting socket 211. The charging terminal 212 is configured to be connected to the charging interface 111 of the electronic product 100. For example, the charging terminal 212 includes multiple contacts, which are VBUS (Voltage Bus voltage terminal) and a ground terminal, which are respectively connected to the first terminal 113 and the second terminal 114 in the charging interface 111. For example, the first terminal 113 is also VBUS, and the second terminal 114 is a ground terminal, and a charging circuit is formed.
[0074] The charging device 200 also includes a magnetic component 2, which is disposed in the connection seat 211. When the coil 10 in the connection structure 1 is energized, the magnetic component 2 and the coil 10 attract each other, so that the electronic product 100 maintains a stable connection with the charging device 200, and the electronic product 100 is charged. When charging is completed or the electronic product 100 needs to be removed, the electrical connection of the coil 10 is disconnected by the controller 20. For example, in the aforementioned embodiment, the switch 21 outputs an opening signal and a closing signal, and the electrical connection of the coil 10 is disconnected by the microcontroller unit 22. The attraction between the coil 10 and the magnetic component 2 is reduced, and the electronic product 100 can be directly removed from the charging device 200. The user can complete it with one hand, which improves the user experience and is suitable for application scenarios that are not suitable for operation with both hands.
[0075] like Figure 6 As shown, the embodiment of the utility model also includes another charging device 200, which includes a connection seat 211 and a connection structure 1 as described in the above embodiment, a charging terminal 212 is provided on the connection seat 211, the connection structure 1 is provided inside the connection seat 211, and a switch 21 is provided on the outer surface of the charging device 200, and the coil 10 can be powered on and off by the micro control unit 22. The coil 10 in this embodiment can be connected to the power supply of the charging device 200, and there is no need to provide an additional power supply for the coil 10. When the electronic product 100 is completely powered off, the connection structure 1 can also work normally.
[0076] like Figure 7 As shown, the embodiment of the utility model also includes a Figure 6 The charging device 200 shown corresponds to the electronic product 100, which includes a housing 110, a power board 120 and a magnetic component 2, wherein the power board 120 and the magnetic component 2 are arranged inside the housing 110. Preferably, the magnetic component 2 can be made of a magnetic metal part, and during normal use of the electronic product 100, it will not generate a magnetic field that interferes with the electronic product 100, nor will it attract small particles of metal, thereby avoiding affecting the circuit structure of the electronic product 100.
[0077] The housing 110 is provided with a charging interface 111, which is electrically connected to the power board 120, and the charging device 200 can supply power to the power board 120 through the charging interface 111. When the coil 10 in the charging device 200 is energized, the magnetic component 2 and the coil 10 attract each other, so that the electronic product 100 can be fixedly connected to the charging device 200. When the electronic product 100 needs to be removed, the user can use the controller 20 to disconnect the electrical connection of the coil 10. For example, in the aforementioned embodiment, the switch 21 outputs an opening signal and a closing signal, and the micro control unit 22 disconnects the electrical connection of the coil 10.
