A receiving groove is provided on the surface of the first charging component facing the second charging component, and a retractable third charging component is provided in the receiving groove. A first magnetic member is provided in the third charging component, and a second magnetic member is provided in the first charging component. When the third charging component is pulled out and unfolded, the first magnetic member and the second magnetic member are magnetically attracted to fix the pulled-out and unfolded third charging component in the current position, avoiding sliding after the third charging component is pulled out and unfolded, preventing the movement of the third charging component after being pulled out and unfolded, and thus improving the stability of the pulled-out and unfolded third charging component during wireless charging of the device.

[0020] 2. First conductive contacts are provided on the boundary of the third charging component of the present utility model, and second conductive contacts are provided in the receiving groove. When the first magnetic member and the second magnetic member are magnetically attracted, the first conductive contacts and the second conductive contacts are in contact conduction.

In addition, it can also make the pulling of the third charging component not interfered by the wire, making the pulling of the third charging component easier.

[0021] 3. A third magnetic member is also provided in the first charging component of the present utility model. The second magnetic member and the third magnetic member are arranged in sequence along the direction in which the third charging component is pulled into the receiving groove. When the third charging component is received in the receiving groove, the first magnetic member and the third magnetic member are magnetically attracted, which can fix the third charging component received in the receiving groove in the current position, thereby realizing the magnetic attraction and fixation of the third charging component and the first charging component in the received state, avoiding the sliding and displacement of the third charging component when wireless charging is not required, and improving the stability of the third charging component in the received state.

[0022] 4. The first charging component of the present utility model includes a first housing and a first wireless charging unit provided on the first housing. A first fixing member is provided inside the first housing corresponding to the position of the receiving groove. A first groove and a second groove are formed on the surface of the first fixing member facing the first wireless charging unit.

[0023] 5. The receiving groove of the present utility model includes an opening, and the third charging component is pulled out and unfolded from the opening; the third charging component includes a second wireless charging unit, and the second wireless charging unit is arranged close to the opening.

[0025] 7. A slider is arranged on the boundary of the second housing of the present utility model, a sliding groove is formed between the first fixing member and the side wall of the receiving groove, and the slider slides in the sliding groove. Through the arrangement of the slider and the sliding groove, it can make the third charging component slide on the first charging component more simply and conveniently. In addition, the sliding groove formed between the first fixing member and the side wall of the receiving groove limits the slider, and the slider is only limited to slide in the sliding groove and cannot move towards the inside of the first housing, thereby improving the overall sliding stability of the slider.

[0026] 8. The slider, the first conductive contact and the first magnetic member of the present utility model are arranged at the same end relative to the second wireless charging unit; when the slider abuts against the opening, the first magnetic member and the second magnetic member are magnetically attracted, and the first conductive contact and the second conductive contact are in contact and conduct. When the third charging component is pulled out and unfolded, by the slider abutting against the opening, it is determined that the third charging component is pulled out and unfolded in place, so that the first conductive contact on the third charging component and the second conductive contact on the second charging component can be correspondingly contacted to realize circuit conduction, and the third charging component in the unfolded state is magnetically fixed by the magnetic attraction between the first magnetic member and the second magnetic member, avoiding the sliding of the third charging component in the unfolded state, thereby ensuring the stability of the circuit conduction between the third conductive component and the first conductive component after unfolding.

For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present utility model can be understood according to the specific circumstances

[0047] In addition, the terms "installed", "set up", "provided with", "connected", and "linked" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there can be internal communication between two devices, components, or parts. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0048] Please refer to Figures 1 - 5 , a first embodiment of the present utility model provides a wireless charger 1, which includes a first charging component 10 and a second charging component 20 hinged to the first charging component 10. A receiving groove 141 is provided on the surface of the first charging component 10 facing the second charging component 20, and a pullable third charging component 30 is provided in the receiving groove 141; a first magnetic member 31 is provided in the third charging component 30, and a second magnetic member 11 is provided in the first charging component 10; when the third charging component 30 is pulled out and unfolded, the first magnetic member 31 and the second magnetic member 11 are magnetically attracted.

[0049] Specifically, the first charging component 10, the second charging component 20, and the third charging component 30 are used for wirelessly charging electronic devices such as mobile phones, smart wearable devices, and headphones. Specifically, when a mobile phone, a smart wearable device, or a headphone is placed on the surfaces of the first charging component 10, the second charging component 20, and the third charging component 30, it can automatically sense and charge them. Specifically, the first charging component 10 is used for wirelessly charging a first device to be charged on a first charging area 143 on the surface of the first charging component 10. The second charging component 20 is used for wirelessly charging a second device to be charged on a second charging area 211 on the surface of the second charging component 20. The third charging component 30 is used for wirelessly charging a third device to be charged on a third charging area 331 on the surface of the third charging component 30. Therefore, the wireless charger 1 in this embodiment can simultaneously charge three devices to be charged to meet the charging requirements for different devices or multiple devices. In this embodiment, preferably, the first device to be charged can be a mobile phone or a tablet, the second device to be charged can be a headphone, and the third device to be charged can be a smart wearable device, such as a smart watch. Thus, the combination of the wireless charging functions for a mobile phone or a tablet, a headphone, and a smart watch is realized, enabling the wireless power supply in this embodiment to meet the wireless charging requirements of users' common electrical devices.

[0050] More specifically, the articulation of the first charging component 10 and the second charging component 20 enables the rotation or folding of the first charging component 10 relative to the second charging component 20. That is to say, the second charging component 20 can act as a base, and the first charging component 10 can be unfolded at an angle relative to the second charging component 20, and this angle can be 0 - 360 degrees. Moreover, after the first charging component 10 is stored, the side of the first charging component 10 facing away from the first charging area 143 will be in contact with the second charging area 211 provided on the second charging component 20, and the first charging area 143 provided on the first charging component 10 will be exposed to the outside, realizing the storage of the first charging component 10 on the second charging component 20, thus completing the storage of the wireless charger 1. In addition, after the first charging component 10 rotates or folds, it can also change from the storage state to the folded state, while realizing wireless charging for the mobile phone, it can also form a support for the mobile phone and play the role of a bracket.

[0051] More specifically, on the side of the first charging component 10 close to the second charging component 20, that is to say, on the side of the first charging component 10 facing away from the first charging area 143, a receiving groove 141 is provided, and the third charging component 30 can be pulled and inserted into this receiving groove 141 to complete the storage of the third charging component 30; and by pulling, part of the third charging component 30 can be separated from this receiving groove 141 and enter the outside to complete the unfolding of the third charging component 30. Moreover, the unfolding of the third charging component 30 specifically requires that all areas of the third charging area 331 of the third charging component 30 are separated from the receiving groove 141 and exposed to the outside in order to realize wireless charging for the smart wearable device.

[0052] It should be noted that the thickness of the third charging component 30 is less than or equal to the depth of the receiving groove 141. Therefore, when the first charging component 10 is folded and stored on the second charging component 20, it is avoided that the third charging component 30 protrudes relative to the side of the third charging component 30 where the receiving groove 141 is provided, which affects the fitting of the side of the first charging component 10 facing away from the first charging area 143 and the second charging area 211 provided on the second charging component 20. Therefore, when both the first charging component 10 and the third charging component 30 are in the storage state, the overall thickness of the wireless charger 1 is only the thickness of the superposition of the first charging component 10 and the third charging component 30, making the structure of the wireless charger 1 more compact, with a small overall volume, and being convenient for carrying and storage. Moreover, in the wireless charger 1 in the overall storage state, the third charging component 30 will be surrounded by the first charging component 10 and the second charging component 20, improving the protection effect on the third charging component 30 and also realizing the limitation of the third charging component 30. In addition, through the hinge connection between the first charging component 10 and the second charging component 20, and the slidable storage of the third charging component 30 in the receiving groove 141, the wireless charger 1 in this embodiment can have multiple forms, and can realize wireless charging from one electronic device to three electronic devices simultaneously. When in use, it can be selectively unfolded into various use forms, and the use is more flexible and convenient.

[0053] It can be understood that a first magnetic member 31 can be provided on the third charging component 30, and a corresponding second magnetic member 11 can be provided on the first charging component 10. After the third charging component 30 is slid out and unfolded, the first magnetic member 31 and the second magnetic member 11 can be magnetically attracted and fixed to fix the slid out and unfolded third charging component 30 at the current position, avoiding the situation of sliding after the third charging component 30 is slid out and unfolded, preventing the movement of the third charging component 30 after it is slid out and unfolded, and further improving the stability of the slid out and unfolded third charging component 30 during wireless charging of the device.

[0054] Please refer to Figure 4 and Figure 5 , further, a first conductive contact 32 is provided on the boundary of the third charging component 30, and a second conductive contact 12 is provided in the receiving groove 141; when the first magnetic member 31 and the second magnetic member 11 are magnetically attracted, the first conductive contact 32 and the second conductive contact 12 are in contact and conduct electricity.

[0055] Understandably, by setting the first conductive contact 32 and the second conductive contact 12, after the first conductive contact 32 contacts the second conductive contact 12, the circuit between the first charging component 10 and the second charging component 20 can be conducted, which is easy to integrate with other electronic components and avoids the damage of the wire caused by the pulling of the wire when using a wire connection. In addition, the pulling of the third charging component 30 is not interfered by the wire, making the pulling of the third charging component 30 easier.

[0056] It should be noted that the circuit between the first charging component 10 and the second charging component 20 is only conducted when the first conductive contact 32 contacts the second conductive contact 12 after the third charging component 30 is pulled out and unfolded, and is not conducted in the storage state, which can effectively avoid wireless charging caused by accidental contact when the smart wearable device does not need to be charged, reduce energy consumption, and improve the overall energy efficiency of the wireless charger 1. In addition, it can also prevent short circuits and accidental discharges, thereby improving the safety of the circuit.

[0057] Please refer to Figure 5 , further, a third magnetic member 13 is also provided in the first charging component 10; the second magnetic member 11 and the third magnetic member 13 are arranged in sequence along the direction in which the third charging component 30 is pulled into the receiving groove 141; when the third charging component 30 is received in the receiving groove 141, the first magnetic member 31 and the third magnetic member 13 are magnetically attracted.

[0058] Understandably, by setting the magnetic attraction between the first magnetic member 31 and the third magnetic member 13, the third charging component 30 received in the receiving groove 141 is fixed at the current position, thereby realizing the magnetic attraction fixation between the third charging component 30 and the first charging component 10 in the storage state, and avoiding the sliding and displacement of the third charging component 30 when wireless charging is not required, improving the stability of the third charging component 30 in the storage state.

[0059] Specifically, the second magnetic member 11 is arranged corresponding to the position of the first magnetic member 31 in the third charging component 30 received in the receiving groove 141, and the third magnetic member 13 is arranged corresponding to the position of the first magnetic member 31 in the third charging component 30 that is pulled out and unfolded. Thus, the magnetic attraction fixation of the third charging component 30 in the storage state and the magnetic attraction fixation in the pulled-out and unfolded state can be realized. Therefore, the second magnetic member 11 and the third magnetic member 13 can also be arranged in sequence along the direction in which the third charging component 30 is pulled into the receiving groove 141, so as to realize the magnetic attraction fixation of the third charging component 30 in the storage state and the magnetic attraction fixation in the pulled-out and unfolded state in the pulling direction, making the switching between the magnetic attraction fixation in the storage state and the magnetic attraction fixation in the pulled-out and unfolded state smoother and more fluent.

[0060] Please refer to Figure 5 and Figure 6, Further, the first charging component 10 includes a first housing 14 and a first wireless charging unit 15 disposed within the first housing 14. A first fixing member 16 is provided inside the first housing 14 corresponding to the position of the receiving groove 141. A first groove 161 and a second groove 162 are formed on the surface of the first fixing member 16 facing the first wireless charging unit 15. The second magnetic member 11 and the third magnetic member 13 are respectively located in the first groove 161 and the second groove 162.

[0061] Understandably, the first wireless charging unit 15 corresponds to the first charging area 143 of the first charging component 10, and the first housing 14 can protect the first wireless charging unit 15 therein. The first fixing member 16 is disposed on one side of the first housing 14 close to the second charging component 20, that is, the first wireless charging unit 15 and the first fixing member 16 are arranged in sequence along the direction close to the second charging component 20. A first groove 161 and a second groove 162 are formed on the surface of the first fixing member 16 facing the first wireless charging unit 15. The second magnetic member 11 and the third magnetic member 13 are respectively limited and fixed at the current positions through the first groove 161 and the second groove 162, improving the stability of the second magnetic member 11 and the third magnetic member 13 fixed on the first fixing member 16. In addition, the second magnetic member 11 and the third magnetic member 13 are clamped between the first wireless charging unit 15 and the first fixing member 16, further limiting the second magnetic member 11 and the third magnetic member 13. In addition, it also prevents the second magnetic member 11 and the third magnetic member 13 from being exposed.

[0062] Please refer to Figure 5 and Figure 7 , Further, the receiving groove 141 includes an opening 142, and the third charging component 30 is pulled out and unfolded from the opening 142; the third charging component 30 includes a second wireless charging unit 34, and the second wireless charging unit 34 is disposed close to the opening 142.

[0063] Understandably, the opening 142 of the receiving slot 141 is provided on the boundary of the second housing 33 to penetrate the receiving slot 141, so that the third charging assembly 30 can be pulled out from the side of the first charging assembly 10, and this side is one side of the charging surface that encloses and sets the first charging area 143 on the first charging assembly 10. And a first magnetic member 31 and a second wireless charging unit 34 are sequentially arranged inside the second housing 33 along the pulling and unfolding direction of the third charging assembly 30, so that the second wireless charging unit 34 is closer to the opening 142 relative to the first magnetic member 31. Thus, when the third charging assembly 30 is pulled out and unfolded, the second wireless charging unit 34 can directly break away from the receiving slot 141 and enter the outside first to realize wireless charging of the electronic device, thereby avoiding the situation that a too long charging assembly is not conducive to unfolding charging and storage. At the same time, since the first magnetic member 31 is arranged behind the second wireless charging unit 34, it will not be pulled out, so as to realize magnetic attraction with the second magnetic member 11 and fix the third charging assembly 30 at the current position.

[0064] Please refer to Figure 7 , further, the third charging assembly 30 includes a second housing 33, a second fixing member 35 is arranged inside the second housing 33, a third groove 351 is arranged on the second fixing member 35, and the first magnetic member 31 is located in the third groove 351.

[0065] Understandably, a second fixing member 35 is arranged on one side of the inside of the second housing 33 close to the receiving slot 141, so that the first magnetic member 31 can be limited and fixed at the current position through the third groove 351 on the second fixing member 35, improving the stability of the first magnetic member 31 fixed on the second fixing member 35.

[0066] It should be noted that the second fixing member 35 and the second wireless charging unit 34 are sequentially arranged inside the second housing 33 along the pulling and unfolding direction of the third charging assembly 30, so that the second wireless charging unit 34 can be closer to the opening 142 relative to the first magnetic member 31.

[0067] Please refer to Figure 7 and Figure 8 , further, a slider 36 is arranged on the boundary of the second housing 33, a chute 17 is formed between the first fixing member 16 and the side wall of the receiving slot 141, and the slider 36 slides in the chute 17.

[0068] Understandably, through the arrangement of the slider 36 and the sliding groove 17, the third charging component 30 is realized to perform a pulling and pushing movement in the accommodation groove 141 in a sliding manner. And through the sliding of the slider 36 in the sliding groove 17, it can make the third charging component 30 slide on the first charging component 10 more simply and conveniently. In addition, the sliding groove 17 formed between the first fixing member 16 and the side wall of the accommodation groove 141 limits the slider 36, restricting the slider 36 to only slide within the sliding groove 17 and preventing it from moving into the interior of the first housing 14, thereby improving the overall sliding stability of the slider 36.

[0069] Please refer to Figure 5 and Figure 7 , further, the slider 36, the first conductive contact 32, and the first magnetic member 31 are arranged at the same end relative to the second wireless charging unit 34; when the slider 36 abuts against the opening 142, the first magnetic member 31 and the second magnetic member 11 are magnetically attracted, and the first conductive contact 32 and the second conductive contact 12 are in contact conduction.

[0070] Understandably, arranging the slider 36, the first conductive contact 32, and the first magnetic member 31 at the same end relative to the second wireless charging unit 34 can reserve enough sliding length for the slider 36 to slide in the sliding groove 17, so that the second wireless charging unit 34 can escape from the accommodation groove 141 when the third charging component 30 needs to be pulled out and unfolded to wirelessly charge the smart wearable device. And when the third charging component 30 is pulled out and unfolded, by making the slider 36 abut against the opening 142, it is thereby determined that the pulling and pushing of the third charging component 30 is in place, enabling the first conductive contact 32 on the third charging component 30 and the second conductive contact 12 on the second charging component 20 to be correspondingly in contact to achieve circuit conduction, and magnetically fixing the unfolded third charging component 30 through the magnetic attraction between the first magnetic member 31 and the second magnetic member 11, avoiding the sliding of the unfolded third charging component 30, thereby ensuring the stability of the circuit conduction between the unfolded third conductive component and the first conductive component. And the distance between the end of the slider 36 close to the opening 142 and the opening 142 is less than the distance between the first conductive contact 32 and the opening 142, ensuring that in the storage state of the third charging component 30, and before the slider 36 passes by the second conductive contact 12, the first conductive contact 32 will not be able to contact the second conductive contact 12 for circuit conduction. And in order to ensure that the first conductive contact 32 contacts the second conductive contact 12 only when the slider 36 abuts against the opening 142, the length of the end of the slider 36 close to the opening 142 corresponding to the first conductive contact 32 on the slider 36 can be set to be the same as the distance between the second conductive contact 12 and the opening 142, so that the sliding in-place situation of the third charging component 30 can be determined for circuit conduction when the slider 36 abuts against the opening 142, ensuring that the third charging component 30 will not be able to contact the second conductive contact 12 for circuit conduction in the storage state and the incompletely unfolded state.

[0071] Please refer to Figure 9 Furthermore, the wireless charger 1 further includes a hinge assembly 40. The first charging assembly 10 is hinged to the second charging assembly 20 through the hinge assembly 40. The second charging assembly 20 includes a third housing 21 and a third wireless charging unit 22 disposed within the third housing 21. A first wire passing hole 41 and a second wire passing hole 42 are respectively disposed on the hinge assembly 40 corresponding to the first wireless charging unit 15 and the third wireless charging unit 22. The wires of the first wireless charging unit 15 sequentially pass through the first wire passing hole 41 and the second wire passing hole 42 and are connected to the third wireless charging unit 22.

[0072] It can be understood that through the setting of the hinge assembly 40, the folding and storage between the first charging assembly 10 and the second charging assembly 20 can be realized. And through the settings of the first wire passing hole 41 and the second wire passing hole 42 provided on the hinge assembly 40, the wires connecting the first wireless charging unit 15 and the third wireless charging unit 22 are hidden, so as to protect the wires at the hinge position through the hinge assembly 40.

[0073] Please refer to Figure 9 and Figure 10 Furthermore, the wireless charger 1 further includes a data cable 50. A wire winding assembly 23 and a fourth magnetic member 24 are disposed within the third housing 21. The data cable 50 is wound around the wire winding assembly 23, and the plug 501 of the data cable 50 passes through the third housing 21 and is magnetically attracted to the fourth magnetic member 24.

[0074] It can be understood that the data cable 50 in the wireless charger 1 is a telescopic data cable. Specifically, by winding the data cable 50 around the wire winding assembly 23, the stretching and contraction of the data cable 50 are completed through the rotation of the wire winding assembly 23 relative to the third housing 21, facilitating data connection at a relatively long distance. And a fourth magnetic member 24 is disposed within the third housing 21, so that the plug 501 of the data cable 50 extending out of the third housing 21 can be magnetically attracted to the fourth magnetic member 24, enabling the plug 501 to closely adhere to the surface of the third housing 21 and fixing the plug 501 at the current position, realizing the magnetic attraction and fixation of the plug 501. Without separately setting a storage structure, the storage of the plug 501 of the data cable 50 extending out of the third housing 21 is achieved. In addition, the magnetic attraction and fixation of the plug 501 of the data cable 50 to the fourth magnetic member 24 also avoid the situation of the plug 501 shaking and being arbitrarily folded and bent after extending out of the third housing 21, improving the service life of the data cable 50.

[0075] Optionally, the fourth magnetic member 24 can be disposed on the side edge within the third housing 21, so as to realize the magnetic attraction and fixation of the data cable 50 on the side surface corresponding to the side edge of the third housing 21, thereby improving the overall storage stability and making the wireless charger 1 more beautiful in the storage state.

[0076] Compared with the prior art, the wireless charger of the present utility model has the following advantages:

[0077] 1. The wireless charger provided by the present utility model includes a first charging component and a second charging component hinged to the first charging component. A receiving groove is provided on the side of the first charging component facing the second charging component, and a retractable third charging component is provided in the receiving groove; a first magnetic member is provided in the third charging component, and a second magnetic member is provided in the first charging component; when the third charging component is pulled out and unfolded, the first magnetic member and the second magnetic member are magnetically attracted to fix the pulled-out and unfolded third charging component in the current position, avoiding sliding after the third charging component is pulled out and unfolded, preventing the third charging component from moving after being pulled out and unfolded, and thus improving the stability of the pulled-out and unfolded third charging component during wireless charging of the device.

[0078] 2. First conductive contacts are provided on the boundary of the third charging component of the present utility model, and second conductive contacts are provided in the receiving groove; when the first magnetic member and the second magnetic member are magnetically attracted, the first conductive contacts and the second conductive contacts are in contact and conduct. By providing the first conductive contacts and the second conductive contacts, the circuit conduction between the first charging component and the second charging component is realized, avoiding damage to the wire caused by pulling the wire when using a wire connection. In addition, it can also make the pulling of the third charging component not interfered by the wire, making the pulling of the third charging component easier.

[0079] 3. A third magnetic member is further provided in the first charging component of the present utility model; the second magnetic member and the third magnetic member are arranged in sequence along the direction in which the third charging component is pulled into the receiving groove; when the third charging component is received in the receiving groove, the first magnetic member and the third magnetic member are magnetically attracted, and the third charging component received in the receiving groove can be fixed in the current position, thereby realizing the magnetic attraction and fixation between the third charging component and the first charging component in the received state, avoiding the sliding and displacement of the third charging component when wireless charging is not required, and improving the stability of the third charging component in the received state.

[0080] 4. The first charging component of the present utility model includes a first housing and a first wireless charging unit provided on the first housing. A first fixing member is provided inside the first housing corresponding to the position of the receiving groove. A first groove and a second groove are formed on the side of the first fixing member facing the first wireless charging unit. The second magnetic member and the third magnetic member are respectively located in the first groove and the second groove to limit and fix the second magnetic member and the third magnetic member in the current position through the first groove and the second groove, improving the stability of the second magnetic member and the third magnetic member fixed on the first fixing member.

[0081] 5. The receiving groove of the present utility model includes an opening, and the third charging component is pulled out and unfolded from the opening; the third charging component includes a second wireless charging unit, and the second wireless charging unit is arranged close to the opening, so that when the third charging component is pulled out and unfolded, the second wireless charging unit can directly break away from the receiving groove and enter the outside to realize wireless charging of the electronic device, thereby avoiding the situation that setting a too long charging component is not conducive to unfolding charging and storage.

[0083] 7.

Through the arrangement of the slider and the sliding groove, it can make the third charging component slide on the first charging component more simply and conveniently. In addition, the sliding groove formed between the first fixing member and the side wall of the receiving groove limits the slider, and the slider is only limited to slide in the sliding groove and cannot move into the first housing, thereby improving the overall sliding stability of the slider.

[0084] 8. The slider, the first conductive contact and the first magnetic member of the present utility model are arranged at the same end relative to the second wireless charging unit; when the slider abuts against the opening, the first magnetic member and the second magnetic member are magnetically attracted, and the first conductive contact and the second conductive contact are in contact and conduct. When the third charging component is pulled out and unfolded, by the slider abutting against the opening, it is determined that the third charging component is pulled out and unfolded in place, so that the first conductive contact on the third charging component and the second conductive contact on the second charging component can be correspondingly contacted to realize circuit conduction, and the third charging component in the unfolded state is magnetically fixed by the magnetic attraction between the first magnetic member and the second magnetic member, avoiding the sliding of the third charging component in the unfolded state, thereby ensuring the stability of the circuit conduction between the third conductive component and the first conductive component after unfolding.
