[0047] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0048] See Figure 1 This application discloses a smart device 1. The smart device 1 may include a charging head 100 and a device host 200. One end of the charging head 100 may be connected to the device host 200, and the other end may be connected to an external power source to charge the device host 200.

[0049] In this embodiment, the smart device 1 can be a smartwatch, smart bracelet, TWS earphone, printer, projector, mobile phone, or drone, etc. It uses a magnetic spring pin contact charging method, which enables efficient signal and current transmission within a confined space. The compact structure of the magnetic spring pin provides more possibilities for the internal space design of the smart device 1, satisfying both the miniaturization requirements of the smart device 1 and ensuring the practicality of the charging function. This embodiment uses a smartwatch as an example for illustration.

[0050] See Figures 2 to 5 In some embodiments, the device host 200 is provided with a host pin 201 and a first magnetic element 202. The host pin 201 provides a charging function for the device host 200, and the first magnetic element 202 is provided corresponding to the host pin 201 to provide magnetic attraction when the device host 200 is charging.

[0051] In some embodiments, the charging head 100 may include a charging housing 10, a first circuit board 20, and a charging probe 30. The charging housing 10 has an inner cavity 101 with an opening 101a facing a first direction X. The first circuit board 20 is disposed in the inner cavity 101, and the charging probe 30 is disposed in the inner cavity 101. One end of the charging probe 30 is connected to the first circuit board 20, and the other end of the charging probe 30 extends along the first direction X toward the opening 101a. That is, the other end of the charging probe 30 away from the first circuit board 20 is a free end, which can be used to electrically connect with the host pin 201 on the device host 200 to realize circuit conduction so as to charge the device host 200.

[0052] It is understood that the other end of the charging probe 30 extends toward the opening 101a along the first direction X, including: the other end of the charging probe 30 may be located in the inner cavity 101 but close to the opening 101a; or, the other end of the charging probe 30 may extend out of the opening 101a, that is, the other end of the charging probe 30 is exposed outside the charging housing 10; or, the other end of the charging probe 30 is located at the opening 101a and is substantially aligned with the charging housing 10. This embodiment does not specifically limit this.

[0053] In some embodiments, the charging head 100 may further include a second magnetic element 40 disposed on the charging housing 10. The second magnetic element 40 is disposed at a distance from the charging probe 30 in the radial direction of the charging probe 30. The second magnetic element 40 is configured to attract the first magnetic element 202 of the device host 200.

[0054] With this setup, when the device host 200 needs charging, simply align the charging port of the charging head 100 with the charging slot 203d of the device host 200. This causes the second magnetic component 40 inside the charging housing 10 to face the first magnetic component 202 on the device host 200. The first magnetic component 202 and the second magnetic component 40 attract each other, and the magnetic attraction between them ensures that the charging head 100 and the device host 200 are firmly engaged. This allows the charging probe 30 to connect to the host pin 201 and conduct electricity. At this time, since the other end of the charging head 100 is connected to an external power source, the electricity from the external power source will flow sequentially through the first circuit board 20, the charging probe 30, the host pin 201, the second circuit board 204, the battery, and the motherboard inside the device host 200. This charges the battery of the device host 200, ensuring the normal operation of the motherboard and enabling the device host 200 to function. The aforementioned smart device 1 uses the magnetic attraction between the first magnetic component 202 and the second magnetic component 40 to connect the charging probe 30 and the host pin 201, thereby enabling the device host 200 to be charged. This method is simple and convenient to operate, and is more conducive to improving the user's ease of use.

[0055] Optionally, the first magnetic component 202 and the second magnetic component 40 can be made of magnetic materials, for example, both the first magnetic component 202 and the second magnetic component 40 can be magnets. The first magnetic component 202 can be attached to the device host 200 by adhesive bonding, and the second magnetic component 40 can also be attached to the charging housing 10 by adhesive bonding. Alternatively, one of the first magnetic component and the second magnetic component can be a magnet, and the other can be a metal component, as long as they can achieve magnetic connection.

[0056] Furthermore, the number of charging probes 30 can be multiple, for example, two. The two charging probes 30 can be spaced apart along the first direction Y. Correspondingly, the number of host ejector pins 201 can be the same as the number of charging probes 30. The charging probe 30 can be a spring-loaded ejector pin, comprising a needle tip, a needle tube, and a spring. The needle tip can extend and retract relative to the needle tube under the action of the spring to ensure good contact with the inner wall of the needle tube during operation, thereby providing stable current conduction and low impedance.

[0057] In some embodiments, the charging head 100 may further include an insulating member 50 disposed between the second magnetic member 40 and the charging probe 30. The insulating member 50 is configured to prevent the second magnetic member 40 and the charging probe 30 from simultaneously contacting the host pin 201 on the device host 200. By providing the insulating member 50 between the second magnetic member 40 and the charging probe 30 of the charging head 100, the risk of the second magnetic member 40 and the charging probe 30 simultaneously contacting the probe of the device host 200 due to misalignment can be avoided when the charging head 100 is connected to the device host 200 for charging. This reduces or avoids the risk of short circuit between the second magnetic member 40 and the charging probe 30, thereby improving the service life of the smart device 1.

[0058] Optionally, the insulating component 50 can be made of materials with good insulating properties such as plastic, rubber, or ceramic, as long as it can satisfy the blocking and insulating functions of the charging probe 30 and the second magnetic component 40. The specific implementation method is not limited in this application.

[0059] The device host 200 and the charging head 100 in the embodiments of this application will be described in detail below.

[0060] See Figures 3 to 5 The smart device 1 in this embodiment includes a charging head 100 and a device host 200 as described above. The first magnetic component 202 of the device host 200 is attracted to the second magnetic component 40, and the host pin 201 of the device host 200 is connected to the charging probe 30 so that the device host 200 can be charged through the charging head 100.

[0061] In some possible implementations, the device host 200 includes a host housing 203 and a second circuit board 204. The host housing 203 is provided with a host pin 201 and a first magnetic element 202. The host pin 201 is electrically connected to the second circuit board 204. The contacts of the host pin 201 are exposed outside the host housing 203. The first magnetic element 202 is configured to attract with the second magnetic element 40 so that the host pin 201 is connected to the charging probe 30.

[0062] Optionally, the second circuit board 204 can be a printed circuit board, a flexible circuit board, or a rigid-flex board, etc. In this embodiment, the second circuit board 204 is a flexible circuit board, one end of which is soldered to the host pin, and the other end is electrically connected to the motherboard inside the host device 200.

[0063] In some embodiments, the distance from the end of the second magnetic element 40 near the host ejector pin 201 to the charging probe 30 (e.g.) Figure 3 D1 in the figure is larger than the diameter of the contact point of the host ejector pin 201 (e.g., Figure 3(D2 in the diagram). With this configuration, when the charging probe 30 of the charging head 100 is aligned with the host ejector pin 201 to conduct charging, since the distance between the charging probe 30 and the second magnetic component 40 is greater than the contact diameter of the host ejector pin 201, even if the two are misaligned, the charging probe 30 and the second magnetic component 40 will not simultaneously contact the host ejector pin 201, thus preventing the host ejector pin 201 from being short-circuited, which is more conducive to charging safety.

[0064] In some possible embodiments, the side wall surface 203a of the main unit housing 203 is provided with a mounting hole 203b, and the main unit ejector pin 201 passes through the mounting hole 203b so that the contact of the main unit ejector pin 201 is exposed outside the main unit housing 203. The side wall surface 203a is provided with a protruding ring portion 203c, which is wrapped around the outer periphery of the mounting hole 203b to form a charging groove 203d. The second magnetic member 40 and the insulating member 50 extend into the charging groove 203d, and the charging housing 10 abuts against the protruding ring portion 203c.

[0065] By forming a charging slot 203d by providing a protruding ring portion 203c on the side wall surface 203a, the internal space of the main housing 203 can be avoided, and the second magnetic component 40 can cooperate with the charging slot 203d on the main housing 203, which is more conducive to the alignment of the charging head 100. Furthermore, the protruding ring portion 203c on the side wall surface 203a forms a limiting effect in the first direction Y, which can prevent the charging probe 30 and the main unit pin 201 from shifting during charging, thereby making the docking of the charging probe 30 and the main unit pin 201 more stable and secure during charging.

[0066] It is understood that the charging slot 203d of the device host 200 is located on the side of the host housing 203. When charging, the charging head 100 can be directly connected to the charging slot 203d on the side wall 203a without removing or flipping the device host 200, which can improve the convenience of charging.

[0067] In some possible embodiments, the first magnetic element 202 is a ring-shaped magnetic element, with its two sides having opposite magnetic poles in the first direction Y. The first direction Y intersects the first direction X. Since the second magnetic element 40 is attracted to the first magnetic element 202, its two sides also have opposite magnetic poles in the first direction Y. This arrangement allows the first magnetic element 202 to have a stronger magnetic force, so that even if the first magnetic element 202 is located inside the main unit casing 203, it can be more firmly attracted to the second magnetic element 40 through the main unit casing 203.

[0068] For example, one side of the first magnetic element 202 can be magnetized as the N pole, and the other end of the second magnetic element 40 can be magnetized as the S pole. The host pin 201 can be located inside the annular first magnetic element 202. Assuming there are two host pins 201 for charging probe 30, the end of the first magnetic element 202 near one of the host pins 201 is the N pole, and the side of the first magnetic element 202 near the other host pin 201 is the S pole.

[0069] Correspondingly, the side of the second magnetic component 40 corresponding to the N pole is the S pole, and the side of the second magnetic component 40 corresponding to the S pole is the N pole. During charging, if the charging head 100 is properly connected to the charging slot 203d on the device host 200, the N pole on the device host 200 will attract the S pole on the charging head 100, and the S pole on the device host 200 will attract the N pole on the charging head 100, so that the host pin 201 on the device host 200 can be correctly connected to the charging probe 30 on the charging head 100. If the charging head 100 is connected to the charging slot 203d on the device host 200 in reverse, the N pole on the device host 200 will repel the N pole on the charging head 100, and the S pole on the device host 200 will repel the S pole on the charging head 100. This will prevent the host pin 201 on the device host 200 from docking with the charging probe 30 on the charging head 100, thus reminding the user to change the direction of the charging head 100 and preventing the charging head 100 from being inserted into the charging slot 203d on the device host 200 in reverse.

[0070] It should be noted that, in this application, the first direction X is the direction in which the charging head 100 is plugged into or unplugged from the device host 200 during charging, and the first direction Y is perpendicular to the first direction X, and can be the radial direction of the charging probe 30.

[0071] In some embodiments, see Figures 6 to 7 The charging housing 10 may include a first housing 11 and a second housing 12, with the second housing 12 connected to the first housing 11. The second housing 12 has an inner cavity 101 with an opening 101a. Optionally, the first housing 11 and the second housing 12 may be integrally formed. Alternatively, the first housing 11 and the second housing 12 may be connected by a snap-fit ​​mechanism, which is simple to operate and easy to assemble. Alternatively, the first housing 11 and the second housing 12 may be fixedly connected by adhesive bonding. This configuration eliminates the need for additional structures for screws or bolts or snap-fit ​​mechanisms on the first housing 11 and the second housing 12, thereby reducing the space occupied by the inner cavity 101 of the charging housing 10 and facilitating the stacking of internal components of the charging head 100.

[0072] To better utilize the insulating component 50 and prevent short circuits, please refer to... Figure 8 and Figure 9In some possible embodiments, the second magnetic element 40 has an end face 40a, on which a groove 40b is provided. The insulating element 50 is accommodated in the groove 40b. The insulating element 50 has a first surface 50a and a second surface 50b disposed opposite to each other in a first direction X. The first surface 50a abuts against the groove 40b, and the second surface 50b protrudes or is flush with the end face 40a. The charging probe 30 passes through the insulating element 50. By creating a groove 40b on the second magnetic component 40 to house the insulating component 50, the distance between the free end of the charging probe 30 and the second magnetic component 40 is increased. This allows the insulating component 50 in between to provide greater insulation, thus improving the effectiveness of preventing short circuits in the host pin 201. Furthermore, it reduces the area of ​​the end face 40a of the second magnetic component 40, thereby reducing the contact area between the second magnetic component 40 and the host housing 203 of the device host 200. This mitigates the risk of the second magnetic component 40 overheating and causing burns to the host housing 203. Simultaneously, while maintaining sufficient magnetic force, creating the groove 40b on the second magnetic component 40 also reduces its weight, contributing to a lighter overall design of the charging head 100.

[0073] Furthermore, by creating a groove 40b on the second magnetic component 40, the insulating component 50 is housed in the groove 40b, with the first surface 50a abutting against the groove 40b. The groove 40b of the second magnetic component 40 can provide load-bearing force in the first direction X for the installation of the insulating component 50, and also provides a larger mounting surface for the insulating component 50. In this way, when the insulating component 50 is fixed to the second magnetic component 40 by adhesive bonding, the insulating component 50 and the second magnetic component 40 can have a larger contact area, which is more conducive to the stability of the connection of the insulating component 50.

[0074] In one example, such as Figure 9 As shown, the second surface 50b of the insulating member 50 can protrude from the end face 40a, that is, the insulating member 50 can be exposed outside the second magnetic member 40 and located outside the groove 40b. In another example, the second surface 50b of the insulating member 50 can be flush with the end face 40a of the second magnetic member 40, and the insulating member 50 can also play a blocking role.

[0075] Preferably, the second surface 50b of the insulating member 50 is flush with the end surface 40a of the second magnetic member 40. This avoids the risk of the second magnetic member 40 and the charging probe 30 simultaneously contacting the host pin 201 due to misalignment. At the same time, the insulating member 50 is not exposed outside the second magnetic member 40, which does not excessively increase the volume of the charging head 100 and is beneficial to the aesthetics of the charging head 100.

[0076] In some possible embodiments, when the second magnetic element 40 has the aforementioned end face 40a, the end face 40a is flush with the contact point of the charging probe 30 in the first direction Y. The first direction Y intersects the first direction X. This arrangement facilitates communication between the charging probe 30 and the host pin 201 on the device host 200, and prevents the charging probe 30 from being exposed to the outside of the second magnetic element 40 when it is not compressed, thus providing better protection for the charging probe 30.

[0077] To better protect the charging probe 30 of the charging head 100, please refer to... Figure 8 and Figure 9 In some possible embodiments, a groove 50c is provided on the second surface 50b, and a first through hole 50d is provided on the bottom wall of the groove 50c. The charging probe 30 passes through the first through hole 50d so that the charging probe 30 extends into the groove 50c. By providing a groove 50c on the second surface 50b of the insulating member 50 and opening a first through hole 50d on the bottom wall of the groove 50c, the charging probe 30 can be passed through so that its tip is exposed, while the tip of the charging probe 30 can be inserted into the groove 50c. The side wall of the groove 50c provides a protective barrier for the tip of the charging probe 30, so that the tip of the charging probe 30 is not completely exposed to the insulating member 50, thus providing protection. Moreover, it can prevent the charging probe 30 from being attracted to certain metallic foreign objects under the magnetic force of the second magnetic member 40, which could lead to a short circuit and avoid safety hazards.

[0078] In some possible embodiments, one end of the second magnetic element 40 is located in the inner cavity 101, and the other end of the second magnetic element 40 extends out of the inner cavity 101. The second magnetic element 40 has a second through hole 40c extending along the first direction X, and the charging probe 30 passes through the second through hole 40c. It should be noted that the second magnetic element 40 is annular, and when the charging probe 30 passes through the second through hole 40c, it does not contact the sidewall of the second through hole 40c. With this configuration, the annular second magnetic element 40 is sleeved on the outside of the charging probe 30, that is, an annular magnetic element is provided around the charging probe 30. While meeting the attraction force with the first magnetic element 202, the weight of the second magnetic element 40 can be reduced, which is more conducive to the lightweight design of the charging head 100.

[0079] Furthermore, by extending the other end of the second magnetic element 40 out of the inner cavity 101, the second magnetic element 40 can cooperate with the charging slot 203d on the main housing 203, which is more conducive to the alignment of the charging head 100. Moreover, the protruding ring portion 203c on the side wall surface 203a forms a limiting effect in the first direction Y, which can prevent the charging probe 30 and the main unit pin 201 from shifting during charging, thereby making the docking of the charging probe 30 and the main unit pin 201 more stable and firm during charging.

[0080] Optionally, the cross-section of the second magnetic element 40 may be circular, elliptical, or square.

[0081] It is understood that when the second magnetic element 40 is a ring-shaped magnetic element arranged around the outer periphery of the charging probe 30, the second magnetic element 40 cannot provide stable support for the charging probe 30. In order to better achieve a stable connection of the probe, in some possible embodiments, see [reference needed]. Figure 9 and Figure 10 The charging head 100 also includes a connector 60, which passes through the second through hole 40c and connects to the second magnetic component 40. One end of the connector 60 abuts against the first circuit board 20, and the other end of the connector 60 extends along the first direction X to the recess 40b. The recess 40b and the other end of the connector 60 abut against the first surface 50a of the insulating component 50. The connector 60 has a third through hole 60a extending along the first direction X, and the charging probe 30 is inserted into the third through hole 60a.

[0082] By providing a connector 60 between the charging probe 30 and the second magnetic component 40, with the connector 60 passing through the second through hole 40c and the charging probe 30 passing through the third through hole 60a and connected to the connector 60, the charging probe 30 and the second magnetic component 40 are relatively fixed. The connector 60 provides effective constraint for the charging probe 30, making the connection of the charging probe 30 more secure and reliable. Furthermore, the other end of the connector 60, together with the recess 40b, abuts against the first surface 50a of the insulating component 50, further providing sufficient support for the installation of the insulating component 50, thus also contributing to the secure installation of the insulating component 50.

[0083] It should be noted that the connector 60 can be used as a mounting base for the charging probe 30. Since the second magnetic element 40 is annular, there is a gap between it and the charging probe 30. At this time, the charging probe 30 is only constrained at the end connected to the first circuit board 20. Therefore, the connector 60 is a structure used to effectively fix the charging probe 30. The charging probe 30 is relatively fixed to the second magnetic element 40 through the connector 60.

[0084] Optionally, such as Figure 10As shown, the connector 60 may include a main body 61 and a boss 62 connected to the main body 61. The boss 62 abuts between the first circuit board 20 and the second magnetic component 40. The main body 61 passes through the second through hole 40c, and the end of the main body 61 away from the boss 62 is aligned with the recess 40b. By adopting the design of the connector 60 including the main body 61 and the boss 62 connected to the main body 61, the boss 62 can be positioned between the first circuit board 20 and the second magnetic component 40. While utilizing the second magnetic component 40 to provide support for the connector 60, it can also provide a buffering effect, preventing the second magnetic component 40 from directly contacting the first circuit board 20 and causing installation hazards. Furthermore, by utilizing the main body 61 to pass through the second through hole 40c and roughly align it with the groove 40b on the second magnetic component 40, the bottom surface of the groove 40b and the side of the main body 61 away from the boss 62 form a continuous plane, providing a complete support surface for the installation of the insulating component 50, thereby making the connection reliability between the insulating component 50 and the second magnetic component 40 and the connector 60 more favorable.

[0085] Optionally, the side of the protrusion 62 of the connector 60 facing the first circuit board 20 may also be provided with a mounting groove 60b. The mounting groove 60b can be used to accommodate part of the structure of the charging probe 30, so that the charging probe 30 does not occupy additional space in the inner cavity 101, thereby making the internal stacking design of the charging head 100 more reasonable.
