[0022] In order to make the objectives, technical means and advantages of the present application clearer, the embodiments of the present application will be described in more detail below with reference to the drawings.

[0023] Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise stated. The embodiments described in the following illustrative examples do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims. EXAMPLES

[0024] As shown in Fig. 1, an embodiment of the present application provides a charger 10 for charging an electronic device 20. The electronic device 20 may be any electrical device, such as, but not limited to, a mobile phone, a computer, a wearable device, etc.

[0025] The charger 10 may be a charger 10 that needs to be electrically connected to both an electrical device and a power source when in use, or may be a mobile battery that can be electrically connected to an electrical device or a power source separately. The mobile battery has a power storage function and is applied to various scenes such as general office work and travel. The electrical connection may be, for example, a wireless connection that can realize wireless charging using principles such as electromagnetic induction, electromagnetic resonance, and radio waves, or may be a wired connection that can realize wired charging using a method such as a charging line or a data line.

[0026] As shown in FIGS. 2 to 5, the charger 10 includes a case 11 and a first electrical connector 12.

[0027] The case 11 includes a cover 111 and a housing 112, an opening 1121 is provided in the housing 112, the cover 111 is provided corresponding to the opening 1121, the cover 111 has a first charging surface 1111 and a first inner wall surface 1112 facing away from the first charging surface 1111, the cover 111 is provided with a charging port 1113 that penetrates the first charging surface 1111 and the first inner wall surface 1112, and the first electrical connector 12 is provided corresponding to the charging port 1113.

[0028] The first electrical connector 12 and the cover body 111 are relatively movable so that the charger 10 can be switched between a first state and a second state, and in the first state, at least a portion of the first electrical connector 12 is located away from the first inner wall surface 1112 of the first charging surface 1111, as shown in Figures 2 and 3, and in the second state, the first electrical connector 12 is located closer to the first inner wall surface 1112 of the first charging surface 1111, as shown in Figures 4 and 5.

[0029] In the first state, at least a part of the first electrical connector 12 is located on a side away from the first inner wall surface 1112 of the first charging surface 1111, so that at least a part of the first electrical connector 12 protrudes from the first charging surface 1111, which is advantageous for electrical connection between the first electrical connector 12 and an electrical connector of the electronic device 20. In the second state, the first electrical connector 12 is located on a side closer to the first inner wall surface 1112 of the first charging surface 1111, so that the first electrical connector 12 does not protrude from the first charging surface 1111, and is, for example, flush with the first charging surface 1111 or located inside the first charging surface 1111, so that the case 11 plays a role in protecting the first electrical connector 12, and wear of the first electrical connector 12 can be avoided.

[0030] The first electrical connector 12 is an electrical connector of the charger 10 that is electrically connected to the electronic device 20 to charge the electronic device 20. As described above, the first electrical connector 12 and the electrical connector of the electronic device 20 may be connected by wire or wirelessly. In the embodiment of the present application, the connection between the charger 10 and the electronic device 20 is by wire, and the first electrical connector 12 may be, but is not limited to, a pogo-pin type electrical connector, a USB type electrical connector, a type-c type electrical connector, or the like.

[0031] It should be noted that when the charger 10 is used to charge the electronic device 20, the charger 10 can be in a first state so that the first electrical connector 12 of the charger 10 can be conveniently electrically connected to the electrical connector of the electronic device 20. When the charger 10 is in an idle state, the charger 10 can be in a second state to avoid the first electrical connector 12 of the charger 10 from being worn out.

[0032] In the embodiment of the present application, the first electrical connector 12 and the cover 111 being relatively movable may be in a form in which the cover 111 is connected to the housing 112 and the first electrical connector 12 and the case 11 are relatively movable, thereby switching the charger 10 between the first state and the second state. In this case, the entire case 11 does not need to move when the charger 10 is switched between the first state and the second state.

[0033] The lid 111 and the housing 112 may be directly connected or indirectly connected. When the lid 111 and the housing 112 are directly connected, they may be detachably connected. When the lid 111 and the housing 112 are indirectly connected, as shown in FIG. 6, the charger 10 further includes a partition plate 17 located in the case 11 and connected to the housing 112, and the lid 111 is connected to the partition plate 17 to realize the connection between the lid 111 and the housing 112. The lid 111 and the partition plate 17 may be detachably connected. Note that the partition plate 17 needs to be provided to avoid the first electric connector 12 so as not to hinder the movement of the first electric connector 12, for example, by providing an escape hole 171 corresponding to the first electric connector 12.

[0034] Any detachable connection in the embodiments of the present application may be a mating connection, a screw connection, or the like, but is not limited thereto.

[0035] An elastic member 16 may be connected between the carrier connected to the first electrical connector 12 and the case 11, for driving the charger 10 to switch from the first state to the second state. For example, the elastic member 16 may be designed to be in a deformed state in the first state and in a restored state in the second state, and the charger 10 may be switched from the first state to the second state by the elastic restoring force of the elastic member 16. In this way, the charger 10 can be switched from the first state to the second state without adding any additional parts, and the structure of the charger 10 can be simplified. The elastic member 16 may be any device having elasticity, such as a compression spring or an elastic piece, and is not limited thereto.

[0036] As shown in FIG. 1, when the electronic device 20 is placed on the first charging surface 1111, the charger 10 can be switched from the second state to the first state by the magnetic attraction force between the first foolproof member 19 of the charger 10 and the second foolproof member 21 of the electronic device 20. As a result, the charger 10 can be switched from the second state to the first state without adding any additional parts, simplifying the structure of the charger 10, and the connection between the electronic device 20 and the charger 10 can be made more stable by the magnetic attraction force between the first foolproof member 19 and the second foolproof member 21. The magnetic attraction force between the first foolproof member 19 and the second foolproof member 21 resists the elastic force of the elastic member 16 and deforms the elastic member 16, thereby realizing the switch of the charger 10 from the second state to the first state.

[0037] In addition, when the charger 10 is switched from the second state to the first state by the magnetic attraction force between the first foolproof member 19 of the charger 10 and the second foolproof member 21 of the electronic device 20, it is possible to achieve an additional effect that the charger 10 can charge only the electronic device 20 that is compatible with the charger 10. For example, the charger 10 can charge only the electronic device 20 that has the second foolproof member 21 that is compatible with the first foolproof member 19, thereby improving the experience and reliability of the charger 10.

[0038] Specifically, as shown in FIG. 7, the first electrical connector 12 and the first fool-proof member 19 are connected to the same carrier, so that when the electronic device 20 is placed on the first charging surface 1111, the first fool-proof member 19 and the second fool-proof member 21 engage with each other to achieve position correction and alignment between the charger 10 and the electronic device 20, and then the first fool-proof member 19 and the second fool-proof member 21 magnetically attract each other and approach each other, driving the first electrical connector 12, the first fool-proof member 19, and the carrier to move, thereby realizing that the charger 10 is in the first state.

[0039] The same carrier to which the first electrical connector 12 and the first foolproof member 19 are connected may be the main circuit board 13 or another component outside the main circuit board 13. Since the main circuit board 13 has many electronic components and is large in size, if the first electrical connector 12 and the first foolproof member 19 are both connected to the main circuit board 13, the magnetic field strength required when the main circuit board 13 moves relative to the cover 111 is high, and the requirements for the first foolproof member 19 are high. Therefore, in the embodiment of the present application, the first electrical connector 12 and the first foolproof member 19 are connected to a component other than the main circuit board 13.

[0040] 6 and 7, the charger 10 includes a main circuit board 13 and a first circuit board 14, both of which are located in the case 11, the first circuit board 14 being closer to the cover 111 than the main circuit board 13, connected to the first electrical connector 12 and the first foolproof member 19, and electrically connected to the first electrical connector 12, and the first circuit board 14 and the case 11 are relatively movable such that the first electrical connector 12 and the case 11 are relatively movable. The main circuit board 13 is connected to the case 11, for example, to a housing 112 of the case 11.

[0041] Furthermore, the mounting seat 142 is connected to the first circuit board 14, and the first electrical connector 12 and the first foolproof member 19 are both connected to the mounting seat 142 on the first circuit board 14. In this manner, after the first electrical connector 12 and the first foolproof member 19 are fixed to the mounting seat 142, they can be attached to the first circuit board 14 together, which is easier to attach than directly attaching the first electrical connector 12 and the first foolproof member 19 to the first circuit board 14.

[0042] 8, the mounting seat 142 may be provided with a first mounting position 1421 for mounting the first foolproof member 19, and the provision of the first mounting position 1421 is useful for mounting and positioning the first foolproof member 19 on the mounting seat 142, and can improve the assembly efficiency between the mounting seat 142 and the first foolproof member 19 while improving the connection stability between the mounting seat 142 and the first foolproof member 19. The first mounting position 1421 may be, but is not limited to, a mounting groove, a mounting hole, etc.

[0043] Specifically, the first mounting position 1421 includes a first sub-mounting groove 1422 corresponding to the first magnet 191, and when the first fool-proof member 19 includes a plurality of first magnets 191, the first mounting position 1421 includes a plurality of first sub-mounting grooves 1422. When the first fool-proof member 19 further includes a third magnet (not shown), the first mounting position 1421 further includes a second sub-mounting groove (not shown) corresponding to the third magnet.

[0044] The mounting seat 142 may be provided with a second mounting position (not shown) for mounting the first electrical connector 12. The provision of the second mounting position helps to mount and position the first electrical connector 12 on the mounting seat 142, improving the assembly efficiency between the mounting seat 142 and the first electrical connector 12 while improving the connection stability between the mounting seat 142 and the first electrical connector 12. The second mounting position may be, but is not limited to, a mounting hole or the like. Specifically, when the first electrical connector 12 is a pogo-pin type electrical connector, the first electrical connector 12 includes a plurality of pins, and the second mounting position may include a first sub-mounting hole corresponding to each pin.

[0045] The mounting seat 142 may be made of a material such as plastic, which has the advantages of low manufacturing cost and light weight.

[0046] First circuit board 14 is directly electrically connected to main circuit board 13, and may be electrically connected, for example, by a conductor or the like. In this case, first circuit board 14 is always electrically connected to main circuit board 13, whether in the first state or the second state.

[0047] As shown in FIGS. 5 and 6 , the first circuit board 14 may be electrically connected to the main circuit board 13 via the second circuit board 15. Specifically, the second circuit board 15 is located in the case 11 and connected to the cover 111. The second circuit board 15 is electrically connected to the main circuit board 13, for example, by a wire or the like. The first circuit board 14 and the second circuit board 15 are movable relative to each other such that the first electrical connector 12 and the cover 111 are movable relative to each other. A second electrical connector 141 is connected to the first circuit board 14, and a second electrical connector 142 is connected to the second circuit board 15. A third electrical connector 151 used in conjunction with electrical connector 141 is connected, and in a first state, second electrical connector 141 comes into contact with and is electrically connected to third electrical connector 151, thereby achieving electrical connection of first circuit board 14 to main circuit board 13 via second circuit board 15, and in a second state, second electrical connector 141 is separated from third electrical connector 151 and the electrical connection is released, thereby achieving disconnection of the electrical connection of first circuit board 14 with second circuit board 15 and main circuit board 13.

[0048] Since first circuit board 14 and second circuit board 15 use a contact-type electrical connection, there is no need to electrically connect first circuit board 14 to second circuit board 15 or main circuit board 13 during the process of first circuit board 14 moving relative to cover body 111, which reduces the restraining force when first circuit board 14 moves relative to cover body 111 and improves the smoothness of movement of first circuit board 14 relative to cover body 111.

[0049] The connection of the second circuit board 15 to the lid 111 may be, but is not limited to, the bonding and connection of the second circuit board 15 and the lid 111. The second electrical connector 141 may be connected to the side of the first circuit board 14 facing the second circuit board 15, and may be, but is not limited to, a conductive elastic sheet that is warped up relative to the first circuit board 14 or a conductive sheet that is arranged flat on the first circuit board 14. The third electrical connector 151 may be connected to the side of the second circuit board 15 facing the first circuit board 14, and may be, but is not limited to, a conductive elastic sheet that is warped up relative to the second circuit board 15 or a conductive sheet that is arranged flat on the second circuit board 15.

[0050] The second circuit board 15 is provided to avoid the first electrical connector 12 and / or the first foolproof member 19, and for example, the second circuit board 15 is provided with an escape hole 152 corresponding to the first electrical connector 12 and / or the first foolproof member 19. The escape hole 152 corresponding to the first electrical connector 12 in the second circuit board 15 and the escape hole 152 corresponding to the first foolproof member 19 may be provided with an interval between them, or may communicate with each other. Of course, the escape hole 152 provided in the second circuit board 15 may be provided directly corresponding to the entire mounting seat 142, and this is not a limitation. The escape hole 171 in the partition plate 17 may be provided directly corresponding to the entire second circuit board 15.

[0051] Elastic member 16 may be provided between first circuit board 14 and cover 111, or may be provided between first circuit board 14 and second circuit board 15. In the embodiment of the present application, elastic member 16 is provided between first circuit board 14 and cover 111 and is a compression spring, guide post 18 is provided on cover 111, the compression spring is fitted onto guide post 18, and guide holes corresponding to guide post 18 are provided in first circuit board 14 and mounting seat 142.

[0052] The diameter of the guide hole in first circuit board 14 may be smaller than the outer diameter of the compression spring, preventing the compression spring from slipping out of the guide hole in first circuit board 14, and / or a gasket and a locking member (e.g., a bolt, etc.) are provided on the side of guide post 18 away from cover 111, the locking member fixes the gasket to the side of guide post 18 away from cover 111, and the outer diameter of the gasket is larger than the outer diameter of the compression spring, preventing the compression spring from slipping out of guide post 18, and first circuit board 14, second circuit board 15 and mounting seat 142 are all provided avoiding guide post 18, for example, a guide hole or the like is provided that avoids guide post 18.

[0053] Next, the first foolproof member 19 will be further described.

[0054] The first fool-proof member 19 is used together with the second fool-proof member 21 of the electronic device 20 when the electronic device 20 is placed on the first charging surface 1111 to correct the relative position between the electronic device 20 and the charger 10, for example, when the electronic device 20 is placed on the first charging surface 1111, the first fool-proof member 19 and the second fool-proof member 21 cooperate with each other to drive the electronic device 20 to move relative to the charger 10. This allows the first electrical connector 12 of the charger 10 and the electrical connector of the electronic device 20 to be aligned, and the charger 10 charges the electronic device 20, improving the charging efficiency when the charger 10 charges the electronic device 20.

[0055] As shown in FIG. 9, the first foolproof member 19 includes a first magnet 191, which has a first magnetic pole 1911 and a second magnetic pole 1912 that are opposite to each other along the extension direction, the polarity of the first magnetic pole 1911 is opposite to the polarity of the second magnetic pole 1912, and the extension direction of the first magnet 191 is approximately parallel to the first charging surface 1111. In this way, when the electronic device 20 is placed on the first charging surface 1111, both of the two magnetic poles of the first magnet 191 of the charger 10 can exert the effect of positioning correction. Compared to the case where the extension direction of the first magnet 191 is designed perpendicular to the first charging surface 1111 so that one magnetic pole in each first magnet 191 can exert the effect of positioning correction, a preferable positioning correction function can be realized with fewer magnets, and the size of the charger 10 can be reduced. Note that the extension direction of the first magnet 191 may be designed approximately perpendicular to the first charging surface 1111, and is not limited thereto.

[0056] The first charging surface 1111 is a surface on which the electronic device 20 is placed when the charger 10 charges the electronic device 20. The first charging surface 1111 may be, but is not limited to, a flat surface, a curved surface, a combination of flat surfaces, a combination of flat surfaces and curved surfaces, or a combination of curved surfaces.

[0057] The electronic device 20 has a second charging surface 22, which is a surface of the electronic device 20 that is adjacent to the first charging surface 1111 when the charger 10 charges the electronic device 20. The second charging surface 22 may be, but is not limited to, a flat surface, a curved surface, a combination of flat surfaces, a combination of flat surfaces, a combination of curved surfaces, or a combination of curved surfaces.

[0058] The second foolproof member 21 includes a second magnet (not shown), which has a third magnetic pole and a fourth magnetic pole that are opposite to each other along the extension direction, the polarity of the third magnetic pole is opposite to the polarity of the fourth magnetic pole, and the extension direction of the second magnet is approximately parallel to the second charging surface 22. In this way, when the electronic device 20 is placed on the first charging surface 1111, both of the two magnetic poles of the second magnet of the electronic device 20 can exert the effect of positioning correction. By designing the extension direction of the second magnet perpendicular to the second charging surface 22, a preferable positioning correction function can be realized with fewer magnets compared to a case in which only one magnetic pole of each second magnet exerts the effect of positioning correction, and the size of the electronic device 20 can be reduced. Note that the extension direction of the second magnet may be designed approximately perpendicular to the first charging surface 1111, and is not limited thereto.

[0059] Specifically, when the electronic device 20 is placed on the first charging surface 1111, one of the third and fourth magnetic poles of the second magnet, which has the opposite polarity to the first magnetic pole 1911, moves in a direction closer to the first magnetic pole 1911, and the other of the third and fourth magnetic poles, which has the opposite polarity to the second magnetic pole 1912, moves in a direction closer to the second magnetic pole 1912, thereby driving the second magnet of the electronic device 20 to align with the first magnet 191 of the charger 10, and achieving alignment between the electrical connector of the electronic device 20 and the first electrical connector 12 of the charger 10.

[0060] The first magnetic pole 1911 may be one of the north and south poles, the second magnetic pole 1912 may be the other of the north and south poles, the third magnetic pole may be one of the north and south poles, and the fourth magnetic pole may be the other of the north and south poles.

[0061] The first foolproof member 19 may include one first magnet 191, or may include multiple first magnets 191 spaced apart, and the number of second magnets included in the second foolproof member 21 of the electronic device 20 may be equal to the number of first magnets 191 included in the first foolproof member 19 of the charger 10, and may be arranged in approximately one-to-one correspondence. When the first foolproof member 19 includes multiple first magnets 191, the multiple first magnets 191 and the multiple second magnets can cooperate with each other to achieve a higher positioning effect, which is advantageous to improving the speed of correction on the first charging surface 1111 of the electronic device 20.

[0062] In the present embodiment, the first fool-proof member 19 includes two first magnets 191 disposed opposite each other and positioned generally on opposite sides of the first electrical connector 12 .

[0063] In addition, if the extension direction of first magnet 191 is approximately parallel to first charging surface 1111, the extension direction of the second magnet may be approximately parallel to second charging surface 22 or approximately perpendicular to second charging surface 22, and if the extension direction of the second magnet is approximately parallel to second charging surface 22, the extension direction of first magnet 191 may be approximately parallel to first charging surface 1111 or approximately perpendicular to first charging surface 1111. When electronic device 20 is placed on first charging surface 1111, first charging surface 1111 may be approximately parallel to second charging surface 22.

[0064] If the first charging surface 1111 is non-planar, the extension direction of the first magnet 191 being approximately parallel / perpendicular to the first charging surface 1111 may mean that the extension direction of the first magnet 191 is approximately parallel / perpendicular to a plane determined by a plurality of points on the first charging surface 1111 that contact the electronic device 20. For example, the first charging surface 1111 has three points that contact the electronic device 20, and the plane determined by the three points is approximately parallel / perpendicular to the extension direction of the first magnet 191.

[0065] If the second charging surface 22 is non-planar, the extension direction of the second magnet being approximately parallel / perpendicular to the second charging surface 22 may mean that the extension direction of the second magnet is parallel / perpendicular to a plane determined by a plurality of points on the second charging surface 22 that contact the charger 10. For example, the second charging surface 22 has three points that contact the charger 10, and the plane determined by the three points is approximately parallel / perpendicular to the extension direction of the second magnet.

[0066] The first foolproof member 19 may simultaneously include a first magnet 191 whose extension direction is approximately parallel to the first charging surface 1111 and a third magnet (not shown) whose extension direction is approximately perpendicular to the first charging surface 1111, and the second foolproof member 21 may include, but is not limited to, a second magnet used in conjunction with the first magnet 191 and whose extension direction is approximately parallel to the second charging surface 22, and a fourth magnet (not shown) used in conjunction with the third magnet and whose extension direction is approximately perpendicular to the second charging surface 22. The third magnet has fifth and sixth magnetic poles that are opposite to each other along the extension direction, and the fourth magnet has seventh and eighth magnetic poles that are opposite to each other along the extension direction.

[0067] In addition, the extension direction of the magnets (e.g., the first magnet 191, the second magnet) described in the embodiments of the present application being parallel to the first charging surface 1111 can be understood to mean that the extension direction of the magnets is approximately parallel to the first charging surface 1111, that is, the included angle between the two is within a first specified range, and the first specified range can be freely designed according to actual needs, for example, the first specified range may be greater than 0° and less than 5°.

[0068] In addition, the extension direction of the magnets (e.g., the first magnet 191, the second magnet, the third magnet, and the fourth magnet) described in the embodiments of the present application being perpendicular to the first charging surface 1111 can be understood to mean that the extension direction of the magnets is approximately perpendicular to the first charging surface 1111, that is, it can be considered to be perpendicular if the included angle between the two is within a second specified range, and the second specified range can be freely designed according to actual needs, for example, the second specified range may be greater than 0° and less than 5°.

[0069] The first fool-proof member 19 may be provided inside the charger 10 or on the surface of the charger 10. In the embodiment of the present application, the first fool-proof member 19 is provided inside the charger 10 and is connected to the same carrier as the first electrical connector 12, i.e., the mounting seat 142. EXAMPLES

[0070] This embodiment is almost similar to the first embodiment, and the following mainly describes the differences between this embodiment and the first embodiment.

[0071] 10, in this embodiment, the first electrical connector 12 and the cover 111 are movable relative to each other in a manner that the first electrical connector 12 is connected to the housing 112 and the cover 111 and the housing 112 are movable relative to each other, thereby switching the charger 10 between a first state and a second state. In this embodiment, the first electrical connector 12 does not need to move when the charger 10 is switched between the first state and the second state.

[0072] The first electrical connector 12 is directly mounted on the main circuit board 13 in the case 11 and is electrically connected to the main circuit board 13, which can simplify the wiring process of the charger 10.

[0073] The partition plate 17 is located within the case 11 and connected to the housing 112, and divides the storage chamber 113 of the case 11 to include a first chamber 1131 and a second chamber 1132, the first chamber 1131 is closer to the cover body 111 than the second chamber 1132, the first chamber 1131 is connected to the charging port 1113 of the cover body 111, the partition plate 17 is provided with a communication hole 172 that communicates between the first chamber 1131 and the second chamber 1132, the main circuit board 13 is provided in the second chamber 1132, the first electrical connector 12 is provided corresponding to the communication hole 172, and the cover body 111 and the partition plate 17 are movable relative to each other so that the cover body 111 and the housing 112 are movable relative to each other.

[0074] The elastic member 16 may be provided between a carrier (e.g., the main circuit board 13) connected to the first electrical connector 12 and the cover 111, and can be driven to switch the charger 10 from the first state to the second state in the same way. For example, the elastic member 16 is designed to be in a deformed state in the first state and in a restored state in the second state, and the charger 10 is switched from the first state to the second state by the elastic restoring force of the elastic member 16. In this way, the charger 10 can be switched from the first state to the second state without adding any additional parts, and the structure of the charger 10 can be simplified.

[0075] When the electronic device 20 is placed on the first charging surface 1111, the gravitational force of the electronic device 20 can cause the charger 10 to switch from the second state to the first state, and the charger 10 can also switch from the second state to the first state without adding any additional components, simplifying the structure of the charger 10. The gravitational force of the electronic device 20 acts against the elastic acting force of the elastic member 16 to deform the elastic member 16 (e.g., the elastic member 16 is compressed), thereby causing the charger 10 to switch from the second state to the first state.

[0076] In the embodiment of the present application, the elastic member 16 may be directly connected between the main circuit board 13 and the cover 111, and / or the elastic member 16 may be provided between the partition plate 17 and the cover 111.

[0077] In the embodiment of the present application, the first fool-proof member 19 may be connected to at least one of the main circuit board 13 , the partition plate 17 , and the cover 111 .

[0078] In the description of this application, the terms "first", "second", etc. are merely for explanation and should not be understood as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific situation. In addition, in the description of this application, unless otherwise specified, "plurality" means at least two, for example, two, three, four, etc. "And / or" describes the related relationship of related objects and indicates that there may be three types of relationships, for example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the related objects before and after are in an "or" relationship.
