[0040] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0041] refer to Figure 1 , Figure 2 and Figure 3 The charging stand 10 disclosed in the present application can be used to charge a device to be charged. In some embodiments, the device to be charged is a wearable device 20, which includes an electronic device 200 and a strap assembly 300. The strap assembly 300 is installed on the electronic device 200 and the electronic device 200 can be worn on the user's wrist through the strap assembly 300. Figure 2The electronic device 200 includes a middle frame 210 and electronic components such as a circuit board and a battery disposed in the middle frame 210. The middle frame 210 is provided with a receiving cavity, and the circuit board, the battery and other electronic components are disposed in the receiving cavity. The middle frame 210 can be made of non-metallic materials such as plastic, rubber, silicone, wood, ceramic or glass, and the middle frame 210 can also be made of metal materials such as stainless steel, aluminum alloy or magnesium alloy. The middle frame 210 can also be a metal injection molded part, that is, the metal material is used to ensure the structural rigidity of the middle frame 210, and the inner surface of the metal body is formed by injection molding with protrusions, grooves, threaded holes and other structures for assembly and positioning.

[0042] In some embodiments, the wearable device 20 is a smart watch, and the housing cavity of the electronic device 200 is provided with a battery, a circuit board, a display screen module 220, a biosensor and other electronic components. The circuit board can integrate the processor, storage unit, communication module and other electronic components of the wearable device 20, and the battery can power the circuit board, the display screen module 220 and other electronic components. The display screen module 220 covers the housing cavity and is connected to the middle frame 210, which can be used to display information and provide an interactive interface for the user. The display screen module 220 can further include a display screen and a cover plate covering the display screen. The display screen can be an LCD (Liquid Crystal Display) screen or an OLED (Organic Light-Emitting Diode) screen, etc., and the cover plate can be a glass cover plate or a sapphire cover plate. The cover plate is transparent and has a relatively high light transmittance. For example, the light transmittance of the cover plate is above 80%. The display screen module 220 can have a touch function, but the touch function is not necessary, and the display screen module 220 is not necessary.

[0043] The middle frame 210 is roughly in the shape of a rectangular frame, and the four corners of the rectangle can be processed into arc transitions through a chamfering process so that the wearable device 20 has better appearance characteristics. In other embodiments, the middle frame 210 can also be in the shape of a circular frame. The side of the middle frame 210, that is, the surface facing away from the receiving cavity, can be provided with a matching structure for installing the strap assembly 300. The strap assembly 300 can form a reliable connection with the middle frame 210 through the matching structure of the middle frame 210 to reliably wear the electronic device 200 to the user's hand. In some embodiments, the strap assembly 300 can also be detached from the middle frame 210 more conveniently so that the user can easily replace the strap assembly 300. For example, the user can purchase a variety of styles of strap assemblies 300 and replace the strap assembly 300 according to the usage scenario to improve the convenience of use. For example, the user can use a more formal strap assembly 300 in formal occasions and a casual strap assembly 300 in leisure and entertainment occasions.

[0044] Continue reading Figure 1 and Figure 2 In the embodiment of the present application, the strap assembly 300 includes two straps, and the two opposite ends of the electronic device 200 are respectively provided with a card slot 203. One end of each of the two straps is connected to the electronic device 200, and the ends of the two straps facing away from the electronic device 200 can be buckled together to form a receiving space, so that the electronic device 200 can be worn on the wrist of the user through the strap assembly 300. In other embodiments, the strap assembly 300 can be a one-piece structure, one end of the strap assembly 300 is connected to one end of the electronic device 200, and the other end of the electronic device 200 can be provided with a buckle for the strap to pass through, and the free end of the strap can pass through the buckle and be fixed to other positions of the strap to form a receiving space, and the size of the receiving space is easy to adjust to facilitate the user to wear.

[0045] Further, refer to Figure 4 , the electronic device 200 may include a back cover 230 connected to the middle frame 210, and after the wearable device 20 is worn on the user's wrist, at least part of the surface of the back cover 230 fits the user's wrist. In an embodiment in which the electronic device 200 includes a display screen module 220, the back cover 230 and the display screen module 220 are arranged at both ends of the middle frame 210 opposite to each other and cover the two ends of the receiving cavity respectively. The back cover 230 may be made of glass, ceramic or plastic, and the back cover 230 may be provided with a detection window for a biosensor such as a heart rate sensor or a blood oxygen sensor. Further, in some embodiments, the electronic device 200 includes a boss 240, which protrudes from the side of the back cover 230 facing away from the display screen module 220, and the boss 240 may be used to set a detection window. When the wearable device 20 is worn on the user's wrist, the boss 240 is used to form a better fit with the wrist, so that the biosensor can detect the user's physiological parameters from the detection window and improve the reliability of the detection.

[0046] Of course, in some embodiments, the boss 240 can be integrally formed with the back cover 230, and the back cover 230 can be integrally formed with the middle frame 210. The electronic device 200 can include two or more biosensors, and the biosensors can be used to detect biological data such as heart rate, respiratory rate, blood pressure or body fat. In some embodiments, the biosensor can also be used to detect the state of motion, such as for step counting. In other embodiments, the wearable device 20 can be a smart bracelet, etc.

[0047] Continue to refer Figure 4In some embodiments, the back cover 230 of the electronic device 200 is provided with a metal contact 250, the metal contact 250 is exposed on the side of the back cover 230 facing away from the display screen module 220, and the metal contact 250 is electrically connected to the circuit board of the electronic device 200. When the electronic device 200 is placed on the charging stand 10, the metal contact 250 can be connected to the charging stand 10, and then the charging stand 10 is used to charge the battery inside the electronic device 200.

[0048] This application is described by taking the charging stand 10 as an example of charging the electronic device 200 of the wearable device 20. It is understandable that in other embodiments, the charging stand 10 can be used to charge other types of devices to be charged, such as smart rings, wireless headphones, etc.

[0049] refer to Figure 3 , Figure 5 and Figure 6 The charging stand 10 includes a shell 11, a circuit board 12, a pin 13 and an adjustment mechanism 14. The shell 11 may be in the shape of a rectangular block, and the cross-sectional area of ​​the shell 11 may be larger than the cross-sectional area of ​​the electronic device 200, so that the electronic device 200 of the wearable device 20 can be placed relatively stably on the shell 11 of the charging stand 10 and charged. The surface of the shell 11 for placing the electronic device 200 may have a concave structure for positioning the electronic device 200. Of course, such a concave structure is not necessary, and the surface of the shell 11 for carrying the electronic device 200 may be a plane.

[0050] The housing 11 may be provided with a power interface 15 for an external power source, and the power interface 15 may be in various forms. For example, the power interface 15 may be a USB type interface, or a Type-C type interface, or a Lightning type interface. The power interface 15 may be used to pluggably connect a power cord and connect to an external power source through the power cord. Of course, in other embodiments, the power interface 15 may be a power cord fixedly connected to the housing 11, and a metal pin is provided at one end of the power cord away from the housing 11. The charging stand 10 may be plugged into an external power source through the metal pin.

[0051] The circuit board 12 is disposed in the housing 11 and is electrically connected to the power interface 15. The circuit board 12 can integrate electronic components such as the control circuit and processing chip of the charging station 10. The ejector pin 13 is disposed in the housing 11, and the ejector pin 13 is made of metal and is electrically connected to the circuit board 12. When the electronic device 200 is placed on the charging station 10 for charging, the ejector pin 13 abuts against the metal contact 250 of the electronic device 200 and is connected to the metal contact 250, so that the charging station 10 can charge the battery of the electronic device 200. Further, in some embodiments, the ejector pin 13 is an elastically retractable structure. For example, the ejector pin 13 may include a syringe and a spring disposed in the syringe, and a needle inserted into the syringe and abutting against the spring, the needle can be telescopically moved relative to the syringe, and in the process of the needle retracting into the syringe, the needle can compress the spring to use the spring to generate an outward thrust on the needle. When the electronic device 200 is placed on the charging dock 10 for charging, the structure of the ejector pin 13 can utilize the compressed spring to create a suitable pressing force between the needle tip and the metal contact 250 , thereby ensuring the reliability of the electrical connection between the ejector pin 13 and the metal contact 250 .

[0052] The adjustment mechanism 14 is connected to the housing 11 and the ejector pin 13, and can drive the ejector pin 13 to move relative to the housing 11. Specifically, the housing 11 may be provided with a through hole (not shown) for the ejector pin 13 to move and retract. When the electronic device 200 is placed in the housing 11, the electronic device 200 drives the adjustment mechanism 14 to move, so as to drive the ejector pin 13 to extend out of the housing 11 from the through hole and abut against the metal contact 250 of the electronic device 200, so that the charging station 10 can charge the electronic device 200. After the electronic device 200 is removed from the housing 11, the adjustment mechanism 14 drives the ejector pin 13 to retract from the through hole and be accommodated in the housing 11, thereby preventing the ejector pin 13 from accidentally conducting with external metal and causing a short circuit in the charging station 10.

[0053] In the related art, the metal ejector pin 13 of the charging stand 10 used to charge the electronic device 200 generally remains protruding from the housing 11. After the user removes the electronic device 200 from the charging stand 10, the user may forget to disconnect the charging stand 10 from the external power supply, and the charging stand 10 is still in the power-on state. At this time, if external metal such as a key, a pin, etc. falls onto the ejector pin 13, the external metal may cause a short circuit in the control circuit of the charging stand 10, causing the charging stand 10 to continue to heat up and cause safety hazards such as a melt shell or a fire. In the charging stand 10 of the embodiment of the present application, after the user removes the electronic device 200 from the charging stand 10, since the ejector pin 13 retracts into the housing 11, even if the user forgets to disconnect the charging stand 10 from the external power supply, the external metal will generally not cause a short circuit in the control circuit of the charging stand 10, thereby improving the safety of electricity use.

[0054] See also Figure 3 , Figure 5 , a positioning groove 11a may be provided on one side of the housing 11 for placing the electronic device 200, and the adjustment mechanism 14 is exposed in the positioning groove 11a, and the positioning groove 11a is used to accommodate the boss 240 when the electronic device 200 is placed in the housing 11, so that the boss 240 presses against the adjustment mechanism 14 and drives the adjustment mechanism 14 to move. Specifically, in the present embodiment, the positioning groove 11a is in the shape of a circular groove and matches the shape of the outer contour of the boss 240. In the process of the electronic device 200 abutting against the housing 11 of the charging stand 10, the positioning of the electronic device 200 in the housing 11 can be achieved through the cooperation between the boss 240 and the positioning groove 11a, so that the metal contact 250 of the electronic device 200 can be reliably positioned to the position of the ejector pin 13, so that the ejector pin 13 can form a reliable electrical connection with the metal contact 250.

[0055] In this embodiment, the adjustment mechanism 14 includes a support member 141 and a connecting rod 143. The shape of the support member 141 matches the shape of the positioning groove 11a and can move in the positioning groove 11a. The support member 141 can be plate-shaped and exposed from the positioning groove 11a to the housing 11. One end of the connecting rod 143 is rotatably connected to the support member 141, and the other end of the connecting rod 143 is rotatably connected to the ejector pin 13. The connecting rod 143 is rotatably connected to the housing 11, and the rotation axis of the connecting rod 143 relative to the housing 11 is located between the rotation axis of the connecting rod 143 relative to the support member 141 and the rotation axis of the connecting rod 143 relative to the ejector pin 13.

[0056] refer to Figure 5 and Figure 6 After the boss 240 enters the positioning groove 11a, the boss 240 can press the support member 141 of the adjustment mechanism 14 to drive the support member 141 to move into the housing 11. Since the connecting rod 143 is connected to the housing 11 by rotation to form a lever mechanism, the other end of the connecting rod 143 can move in the direction opposite to the movement direction of the support member 141, that is, move toward the side close to the electronic device 200, so as to push the ejector pin 13 out of the housing 11. After the ejector pin 13 is extended out of the housing 11, it can be used to conduct with the metal contact 250 of the electronic device 200, so as to charge the electronic device 200 using the charging seat 10.

[0057] In some embodiments, the charging stand 10 may include a first magnetic member 161 and a second magnetic member 163, the first magnetic member 161 and the second magnetic member 163 are spaced apart from each other on the housing 11, and when the electronic device 200 is placed on the charging stand 10, the first magnetic member 161 and the second magnetic member 163 are used to adsorb the electronic device 200. Specifically, in this embodiment, the first magnetic member 161 and the second magnetic member 163 are both magnets. The electronic device 200 is provided with a magnetic fitting member 260 at positions corresponding to the first magnetic member 161 and the second magnetic member 163. The magnetic fitting member 260 may be a magnetic metal member such as iron, cobalt, nickel and alloys thereof, or the magnetic fitting member 260 may be a magnet. When the electronic device 200 is placed on the charging base 10, the magnetic fitting part 260 of the electronic device 200 can be attracted to the first magnetic part 161 and the second magnetic part 163 of the charging base 10, so as to further realize the positioning of the electronic device 200 in the shell 11, so as to correct the position of the electronic device 200 in the shell 11, so as to ensure the accuracy of the alignment of the ejector pin 13 and the metal contact 250, and thereby enable the ejector pin 13 and the metal contact 250 to form a reliable electrical connection.

[0058] In this embodiment, the center line of the first magnetic member 161 and the second magnetic member 163 passes through the center of the positioning groove 11a, the first magnetic member 161 is arranged on the side of the ejector pin 13 away from the positioning groove 11a, and the second magnetic member 163 is arranged on the side of the positioning groove 11a away from the ejector pin 13, that is, the ejector pin 13 and the positioning groove 11a are located between the first magnetic member 161 and the second magnetic member 163. This arrangement can use the first magnetic member 161 and the second magnetic member 163 to further correct the position of the electronic device 200 in the charging stand 10. For example, when the electronic device 200 is deflected relative to the position of the ejector pin 13, the magnetic force can be used to correct the position of the electronic device 200, thereby ensuring the reliability of the electrical connection between the ejector pin 13 and the metal contact 250.

[0059] In some embodiments, the charging station 10 includes a sleeve 17, which is sleeved on the ejector pin 13 and fixedly connected to the ejector pin 13, and the connecting rod 143 is rotatably connected to the sleeve 17, thereby realizing the rotatable connection between the connecting rod 143 and the ejector pin 13. The sleeve 17 may be made of plastic, rubber, or silicone. The setting of the sleeve 17 makes it easy to realize the rotatable connection between the ejector pin 13 and the connecting rod 143, and the sleeve 17 can protect and isolate the ejector pin 13, preventing the ejector pin 13 from accidentally contacting and conducting with metal parts inside the charging station 10.

[0060] Further, in some embodiments, the charging station 10 may include a flexible cable 18, and the ejector pin 13 is electrically connected to the circuit board 12 via the flexible cable 18. During the extension and retraction of the ejector pin 13 relative to the housing 11, the flexible cable 18 may be adaptively deformed to maintain a reliable electrical connection between the ejector pin 13 and the circuit board 12. In other embodiments, the flexible cable 18 may be replaced by a flexible printed circuit (FPC), which can also deform to adapt to the movement of the ejector pin 13 to ensure the reliability of the electrical connection between the ejector pin 13 and the circuit board 12.

[0061] Continue reading Figure 5 and Figure 6 In some embodiments, the adjustment mechanism 14 includes a first reset member 191, which is connected to the support member 141 and the housing 11, and the first reset member 191 is arranged around the positioning groove 11a. In the process of the boss 240 driving the support member 141 to move, the support member 141 stretches the first reset member 191. After the electronic device 200 is removed from the housing 11, the first reset member 191 drives the support member 141 to reset. Specifically, the first reset member 191 can be an elastic silicone member or a rubber member, which can be in a circular ring shape, and one end of the circular ring is connected to the housing 11, and the other opposite end of the circular ring is connected to the support member 141, and the first reset member 191 is arranged around the positioning groove 11a and is sealed with the housing 11 and the support member 141 to avoid a gap between the first reset member 191 and the housing 11 and the support member 141, thereby improving the waterproof and dustproof performance of the charging stand 10. During the process of placing the electronic device 200 on the charging stand 10, when the boss 240 presses the support member 141 to make the support member 141 move into the shell 11, the first reset member 191 is stretched and elastically deformed, and the support member 141 drives the connecting rod 143 to rotate relative to the shell 11, and then drives the ejector pin 13 to extend out of the shell 11 through the connecting rod 143. When the electronic device 200 is removed from the shell 11, the shape of the first reset member 191 is restored, and the support member 141 can be pulled to move outside the shell 11, and then the connecting rod 143 is driven to rotate relative to the shell 11, so as to drive the ejector pin 13 to retract into the shell 11 through the connecting rod 143. In other embodiments, the first reset member 191 can also be replaced by a spring. It is understandable that the arrangement of the first reset member 191 being arranged around the positioning hole is not necessary. For example, the first reset member 191 may include two or more elastic columns arranged at intervals, and the support member 141 can be connected to the shell 11 through the elastic columns.

[0062] Further, refer to Figure 7 and Figure 8In some embodiments, the adjustment mechanism 14 may include a second reset member 193, which is connected to a side of the support member 141 facing the inside of the housing 11, and the second reset member 193 is connected to the housing 11. When the boss 240 drives the support member 141 to move, the support member 141 causes the second reset member 193 to generate a restoring force. After the electronic device 200 is removed from the housing 11, the second reset member 193 drives the support member 141 to reset.

[0063] In one embodiment, the second reset member 193 is a spring. When the boss 240 drives the support member 141 to move into the housing 11, the support member 141 compresses the spring, and the spring accumulates elastic potential energy. After the electronic device 200 is removed from the housing 11, the spring releases the elastic potential energy, thereby pushing the support member 141 to reset. The spring can be set as one or more than two. In an embodiment in which more than two springs are set, the springs can be arranged around the positioning groove 11a at equal intervals, that is, the central angles of adjacent springs are equal, so that the support member 141 is subjected to a more uniform force during the movement relative to the housing 11, thereby achieving smooth movement of the support member 141. In this embodiment, the spring can be replaced by a spring.

[0064] refer to Fig. 9 and Fig.10 In another embodiment, the second reset member 193 includes a first magnet 1931 and a second magnet 1933, the first magnet 1931 is connected to the support member 141, and the second magnet 1933 is connected to the housing 11. In the process of the boss 240 driving the support member 141 to move, a magnetic repulsion force is generated between the first magnet 1931 and the second magnet 1933. After the electronic device 200 is removed from the housing 11, the magnetic repulsion force between the first magnet 1931 and the second magnet 1933 drives the support member 141 to reset. The first magnet 1931 and the second magnet 1933 can be set as one group, or more than two groups can be set. In the embodiment in which the first magnet 1931 and the second magnet 1933 are set in more than two groups, the first magnet 1931 can be arranged around the positioning groove 11a at equal intervals, that is, the central angles of adjacent first magnets 1931 are equal, so that the support member 141 is subjected to a relatively uniform force during the movement relative to the housing 11, thereby achieving a smooth movement of the support member 141.

[0065] In the above embodiment, the combination of the first reset member 191 and the second reset member 193 can avoid fatigue failure of the first reset member 191 and cause failure of the adjustment mechanism 14, thereby ensuring the reliability of the support member 141 and further ensuring the reliability of the charging stand 10.

[0066] Further, in some embodiments, the charging stand 10 includes a baffle (not shown) connected to the shell 11. After the electronic device 200 is removed from the charging stand 10, the baffle covers the through hole and the ejector pin 13. When the electronic device 200 is placed on the charging stand 10, the ejector pin 13 pushes the baffle away from the through hole. The material of the baffle may be plastic, silicone, or rubber. After the ejector pin 13 is retracted into the shell 11, the baffle covers the through hole and the ejector pin 13, thereby preventing dust, liquid, and other foreign matter from entering the through hole, thereby improving the waterproof and dustproof performance of the charging stand 10. This arrangement can also prevent dust, foreign matter, etc. from adversely affecting the telescopic movement of the ejector pin 13, thereby ensuring the service life of the ejector pin 13.

[0067] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
