[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0043] In order to more completely understand the present application and its advantages, the following will be described with reference to the drawings. In the following description, the same reference numerals represent the same parts.

[0044] The present application provides a charging device for a wearable device, which may be, for example, a VR glasses, a VR helmet, a smart watch / bracelet, wireless earphones, etc. The charging device and the wearable device are in a split structure, and each is provided with a connector and an interface, and are connected through the connector and the interface. The charging device is also used to connect a power supply, convert the input voltage and output it to charge the wearable device. The charging device can also perform data transmission with the wearable device through the connection.

[0045] For example, refer to Figures 1-2 , Figure 1 A structural schematic diagram of a charging device provided by an embodiment of the present application is shown. Figure 2 As shown in Figure 1 A plan view of the charging device along the A-A direction is shown. The charging device 100 includes a housing 110, a magnetic connection assembly 120, and an elastic member 130.

[0046] The housing 110 is formed with a receiving space 11, and the upper surface of the housing 110 is provided with an opening 10, and the receiving space 11 communicates with the opening 10.

[0047] The magnetic connection assembly 120 is arranged in the receiving space 11 and includes a connector 21 for connecting the wearable device to charge the wearable device. The connector 21 is arranged in the opening 10 and at least partially located outside the housing 110. The connector 21 also has a gap between the inner side wall of the opening 10 and the housing 110. The magnetic connection assembly 120 is also used to position the wearable device through magnetic force to accurately connect the connector 21 of the magnetic connection assembly 120 with the charging port of the wearable device.

[0048] The elastic member 130 is arranged in the accommodating space 11, and the magnetic connection assembly 120 is connected with the shell 110 through the elastic member 130. Based on the elastic performance of the elastic member 130, the magnetic connection assembly 120 can float relative to the shell 110. Since the joint 21 also has a gap between the inner side wall of the opening 10 formed by the shell 110, the magnetic connection assembly 120 can float in the horizontal direction and the vertical direction under the action of an external force. At the same time, the inner side wall of the opening 10 formed by the shell 110 has a limiting effect on the floating of the magnetic connection assembly 120.

[0049] Further, please refer to Figures 3-4 , Figure 3 The structure diagram of the magnetic connection assembly provided by the embodiment of the present application is shown in Figure 4 The magnetic connection assembly shown in Figure 3 The magnetic connection assembly 120 includes a support 121, a spring needle connector 122, and a first magnetic assembly 123.

[0050] The spring needle connector 122 is inserted into the support 121. The spring needle connector 122 includes a needle shaft, a spring, and a needle tube, for example. The needle tube is inserted into the support 121, the spring and the needle shaft are installed in the needle tube, and the needle shaft is at least partially located outside the needle tube. The end of the needle shaft away from the needle tube forms the joint 21. The spring needle connector 122 is three, for example.

[0051] The first magnetic assembly 123 is installed on the support 121 and is used for positioning the wearable device through magnetic force. The first magnetic assembly 123 includes a first magnet 31 and a second magnet 32. The first magnet 31 and the second magnet 32 are arranged on opposite sides of the spring needle connector 122, respectively. The first magnet 31 and the second magnet 32 have opposite and same polarities.

[0052] Please refer to Figure 5 , Figure 5 The assembly diagram of the support and the magnetic assembly provided by the embodiment of the present application is shown in. The first magnet 31 and the second magnet 32 are installed on the support 121 through the pre-set slot of the support 121.

[0053] In some embodiments, the side of the wearable device connected with the charging device 100 is provided with a second magnetic attraction assembly, for example, including a third magnet for cooperating with the first magnet 31 and a fourth magnet for cooperating with the second magnet 32. The polarities of the first magnet 31 and the second magnet 32 are opposite. Specifically, for example, the first magnet 31 is used for S-pole towards one end of the wearable device and N-pole towards the other end; on the contrary, the second magnet 32 is used for N-pole towards one end of the wearable device and S-pole towards the other end. Correspondingly, the third magnet is used for N-pole towards one end of the first magnet 31 and S-pole towards the other end; the fourth magnet is used for S-pole towards one end of the second magnet 32 and N-pole towards the other end. Through this setting method, when the charging interface of the wearable device is close to the connector 21 of the charging device 100, based on the principle of magnetic attraction of opposite poles and the principle of center-to-center positioning of magnetic field, accurate positioning connection can be achieved, and the charging function of the charging device 100 on the wearable device can be realized.

[0054] Further, please refer to Figure 6 , Figure 6 the assembly drawing of the magnetic attraction type connection assembly and the elastic member provided in the embodiments of the present application.

[0055] The elastic member 130 includes a first connecting part 1, an elastic part 2 and a second connecting part 3 connected in sequence.

[0056] The first connecting part 1 is connected with the supporting member 121, for example, through a two-color integrated molding process and the side edge of the supporting member 121. The second connecting part 3 is used for connecting with the shell 110, for example, through clamping, gluing, screw connection and the like. The elastic part 2 produces elastic deformation when subjected to external force and restores to the original state after the external force disappears.

[0057] In some embodiments, the elastic member 130 can also be a spring, a spring sheet and the like.

[0058] In some embodiments, please refer to Figure 9 , Figure 9 the cross-sectional view of the assembly body and the first circuit board assembly shown in Figure 6 The charging device 100 further includes a first circuit board 140.

[0059] The first circuit board 140 is connected with the needle tube of the pogo pin connector 122, for example, fixed by SMT patch. The first circuit board 140 is provided with a contact pad. When the wearable device is connected with the charging device 100, the needle shaft of the pogo pin connector 122 is in reliable and anti-array electrical contact with the contact pad, so as to ensure the stability of the electrical connection.

[0060] In some embodiments, the charging device 100 further comprises a fixing assembly for fixing part assemblies of the charging device 100. The fixing assembly comprises a screw 4 and a reinforcing piece 5. The first circuit board 140 is provided with a threaded hole, and the support 121 is provided with a threaded groove corresponding to the threaded hole. The screw 4 passes through the threaded hole and the threaded groove, so as to fixedly connect the first circuit board 140 with the support 121. The reinforcing piece 5 is arranged between the screw 4 and the first circuit board 140, and is used for reinforcing the structural strength of the first circuit board 140. The reinforcing piece 5 is, for example, a steel sheet or a plastic sheet. The first circuit board 140 and the support 121 can also be connected by, for example, gluing.

[0061] Please refer to Figure 10 , Figure 10 The exploded view of the charging device provided in the embodiments of the present application. The charging device 100 further comprises a second circuit board 150 and a connecting wire 160.

[0062] The shell 110 comprises an upper cover 111, a base 112 and a counterweight structure 113.

[0063] The upper cover 111 is provided with an opening 10. The upper cover 111 and the base 112 are assembled to form a containing space 11. The upper surface of the upper cover 111 is formed with a positioning groove 14 for placing and positioning the wearable device. The upper cover 111 and the base 112 are assembled by the screw 4. For example, four screws 4 are used to assemble the upper cover 111 and the base 112, and are arranged at the four corners of the upper cover 111 and the base 112, respectively.

[0064] The counterweight structure 113 is arranged in the containing space 11, and is used for improving the balance of the charging device 100, assisting the assembly of the upper cover 111 and the base 112, and improving the structural strength of the charging device 100 as a whole.

[0065] The second circuit board 150 and the connecting wire 160 are arranged in the containing space 11. For example, they are arranged on the bottom surface of the base 112. The base 112 is provided with a through hole 12. The second circuit board 150 can be connected with an external power supply through the through hole 12.

[0066] The shell 110 further comprises a fixing support. Please refer to Figure 11 , Figure 11 The assembly shown in Figure 9 is assembled on the upper cover by the fixing support.

[0067] A fixed bracket 6 is disposed in the receiving space 11 and is fixedly connected to the upper cover 111. The fixed bracket 6 forms a receiving cavity with openings at both the top and bottom. The upper opening of the fixed bracket 6 is at least partially opposite to the opening 10 of the upper cover 111. The assembly formed by the magnetic connection component 120, the elastic element 130 and the first circuit board 140 is disposed in the receiving cavity formed by the fixed bracket 6.

[0068] A connecting cable 160 passes through the lower opening 13 formed by the fixed bracket 6, and its two ends are respectively connected to the first circuit board 140 and the second circuit board 150. The second circuit board 150 is used to convert the power supply voltage and output it to the first circuit board 140. The second circuit board 150 is also used, for example, for data transmission with wearable devices.

[0069] The second connecting portion 3 of the elastic element 130 is connected to the inner wall of the fixed bracket 6. (See reference...) Figure 12 , Figure 12 for Figure 9 The diagram shows a cross-sectional view of the assembly of the body and the fixed bracket. The fixed bracket 6 is provided with a snap-fit ​​part 7, and the second connecting part 3 of the elastic member snaps into the snap-fit ​​part 7. After the upper cover 111 is assembled with the fixed bracket 6, the second connecting part 3 is placed between the upper cover 111 and the fixed bracket 6 to fix the second connecting part 3.

[0070] The surface of the fixing bracket 6 facing away from the first magnet 31 and the second magnet 32 ​​is also provided with a first iron block 8 and a second iron block 9. The first iron block 8 and the first magnet 31 are positioned opposite each other and generate an attractive force, and the second iron block 9 and the second magnet 32 ​​are positioned opposite each other and generate an attractive force. The attractive force of the first magnet 31 on the wearable device body is more than three times greater than the attractive force on the first iron block 8. Similarly, the attractive force of the second magnet 32 ​​on the wearable device body is more than three times greater than the attractive force on the second iron block 9, thereby ensuring that the magnetic connection component 120 can easily attract the wearable device body.

[0071] In practical applications, when a user brings the charging port of the wearable device close to the connector of the charging device 100, the charging port of the wearable device can automatically and precisely align and connect with the connector 21 of the magnetic connection component 120 under the positioning action of the positioning groove 14 and the first magnetic component 123, thus realizing the charging function. After connection, when the wearable device or the charging device 100 is subjected to external force and undergoes relative displacement, the magnetic connection component 120 can float relative to the shell, allowing it to float with the wearable device and thus maintain a stable connection between the connector 21 and the wearable device interface.

[0072] The charging device 100 of the wearable device provided by the embodiment of the present application utilizes the characteristics of the elastic member 130 to enable the magnetic attraction type connection assembly 120 to float relative to the shell 110. When the wearable device or the charging device 100 is subjected to an external force and generates a relative displacement, the magnetic attraction type connection assembly 120 can float with the wearable device to maintain the stable connection of the connector 21 to the wearable device, thereby ensuring the stability of the charging of the wearable device by the charging device 100 and preventing disconnection.

[0073] The embodiment of the present application also provides a wearable device assembly. For example, refer to Figure 13 , Figure 13 The structural schematic diagram of the wearable device assembly provided by the embodiment of the present application is shown. The wearable device assembly 1000 includes the charging device 100 and the wearable device 200.

[0074] The wearable device 200 is placed on the charging device 100 and electrically connected to the charging device 100 to be charged.

[0075] Further, refer to Figure 14 , Figure 14 The plan view of the wearable device assembly provided by the embodiment of the present application along the E-E direction is shown.

[0076] The wearable device 200 includes a shell 210, a charging interface 220 and a second magnetic attraction assembly 230.

[0077] The charging interface 220 is arranged in the shell 210 and penetrates the shell 210 to be exposed to the outside.

[0078] The attractive force between the second magnetic attraction assembly 230 and the first magnetic attraction assembly 123 is smaller than the weight of the charging device 100. The second magnetic attraction assembly 230 includes a third magnet 33 and a fourth magnet 34 with opposite polarities. When the wearable device 200 is connected to the charging device 100, the first magnet 31 and the third magnet 33 and the second magnet 32 and the fourth magnet 34 are opposite to each other and are attracted to each other.

[0079] In actual application, when the charging interface 220 and the connector 21 of the charging device 100 are close to each other, accurate alignment and connection can be achieved based on the principle of magnetic attraction between magnets with opposite polarities and the principle of magnetic field center alignment positioning, thereby realizing the charging function of the charging device 100 to the wearable device 200. Moreover, when the wearable device 200 or the charging device 100 is subjected to an external force and generates a relative displacement, the magnetic attraction type connection assembly 120 can float relative to the shell, so that the magnetic attraction type connection assembly 120 can float with the wearable device 200 to maintain the stable connection of the connector 21 to the charging interface 220.

[0080] The wearable device assembly 100 provided by the embodiments of the present application can be precisely connected by the first magnetic attraction assembly 123 and the second magnetic attraction assembly 230, and the charging device 100 can realize the charging function of the wearable device 200. Moreover, the magnetic attraction type connection assembly 120 of the charging device 100 can float relative to the shell 110 by using the characteristics of the elastic member 130. When the wearable device 200 or the charging device 100 is subjected to external force and generates relative displacement, the magnetic attraction type connection assembly 120 can float with the wearable device 200 to maintain the stable connection of the connector 21 and the charging interface 220, thereby ensuring the stability of the charging of the wearable device 200 by the charging device 100 and preventing disconnection.
