[0044] First embodiment

[0045] Please refer to Figure 1 This embodiment provides a charging system 10, including a charger 100 and a wearable device 200. The charger 100 is used to charge the wearable device 200. The wearable device 200 includes but is not limited to a charging bracelet, a charging watch, a watch phone or other mobile terminals, etc., which are not specifically limited here. In the charging system 10, the charger 100 and the wearable device 200 have the characteristics of reliable connection and good charging stability, and the wearable device 200 has a complete appearance, high aesthetics, and good waterproof effect.

[0046] Please refer to Figure 2The charger 100 includes a base 110 and a first clamp 140 and a second clamp 150 movably disposed on the base 110. The first clamp 140 and the second clamp 150 are disposed opposite to each other and are used to clamp the wearable device 200. A circuit board 131 and a charging terminal 133 electrically connected to the circuit board 131 are provided on the base 110. The charging terminal 133 is used to electrically connect to the wearable device 200 to charge the wearable device 200. The first clamp 140 and the second clamp 150 can provide a reliable clamping force to ensure that the wearable device 200 is reliably connected to the charger 100 during the charging process, and the contact is good, thereby improving the charging stability.

[0047] Furthermore, a charging groove 121 is provided on the base 110, and the charging terminal 133 is located in the charging groove 121. During charging, the charging part of the wearable device 200 is located in the charging groove 121. During charging, the charging groove 121 limits the relative position of the base 110 and the wearable device 200, preventing the wearable device 200 and the charger 100 from moving relative to each other, and effectively improving the problems of unstable connection and poor contact.

[0048] Please refer to Figure 3 and Figure 4 , the base 110 has a receiving cavity, and the circuit board 131 is arranged in the receiving cavity. A first mounting through hole 123 is opened on the bottom wall of the charging groove 121, and the first mounting through hole 123 is connected to the receiving cavity for the charging terminal 133 to pass through. In this embodiment, the base 110 includes a first shell 120 and a second shell 130 connected to each other, and the first shell 120 and the second shell 130 are enclosed to form a receiving cavity, that is, the circuit board 131 is arranged between the first shell 120 and the second shell 130. Optionally, the circuit board 131 is fixed on the second shell 130, and the first shell 120 is covered on the second shell 130 to protect the circuit board 131 and other accessory parts in the receiving cavity, and prevent water, dust, foreign matter, etc. from entering the receiving cavity.

[0049] In this embodiment, the first shell 120 and the second shell 130 are connected in a detachable manner, and the first clamping member 140 and the second clamping member 150 are respectively movably connected to the first shell 120. For ease of description, a group of opposite sides of the first shell 120 connected to the first clamping member 140 and the second clamping member 150 are defined as long sides, and the other group of opposite sides are defined as short sides. Optionally, a group of short sides of the first shell 120 are respectively provided with protrusions 125, and corresponding slots 135 are provided at positions corresponding to the protrusions 125 on the second shell 130, and the shape and size of the slots 135 are adapted to the shape and size of the protrusions 125, so that the protrusions 125 can be inserted into the slots 135, so as to realize the snap connection between the first shell 120 and the second shell 130. Alternatively, in an optional embodiment, a slot 135 may be provided on the first housing 120, and a protrusion 125 may be provided on the second housing 130, so that the protrusion 125 on the second housing 130 is inserted into the slot 135 of the first housing 120 to achieve a snap connection. Of course, this is not limited to this, and the first housing 120 and the second housing 130 may also be connected by bolt connection, screw connection, bonding, magnetic attraction, hinge connection, snap connection, and any one or more connection methods, which are not specifically limited here.

[0050] Furthermore, at least one of the first shell 120 and the second shell 130 is further provided with a limiting portion 126. The limiting portion 126 can be a limiting piece, which plays a role of positioning and limiting when snapping together, and is also convenient for aligning the first shell 120 and the second shell 130 after snapping together, thereby improving the convenience, reliability and sealing of the connection, and also ensuring that the appearance of the base 110 is complete and more beautiful. In this embodiment, the limiting portion 126 is provided on the first shell 120, and the limiting portion 126 is provided close to the protrusion 125.

[0051] A charging groove 121 is provided on the side of the first shell 120 facing away from the second shell 130. Furthermore, a boss 124 is provided on the bottom wall of the charging groove 121. A first mounting through hole 123 is opened on the boss 124. One end of the charging terminal 133 is electrically connected to the circuit board 131. One end of the charging terminal 133 facing away from the circuit board 131 passes through the first mounting through hole 123 and exposes the boss 124.

[0052] Optionally, the number of the charging terminals 133 may be one or more, and the multiple charging terminals 133 are symmetrically distributed about the axis of the base 110. In this embodiment, the number of the charging terminals 133 is two, which are symmetrically arranged on both sides of the base 110, so that the wearable device 200 can be charged from both sides of the base 110, and the operation is more flexible and convenient.

[0053] Optionally, the charging terminal 133 is located in the charging groove 121, and the number of the bosses 124 is also two. The two bosses 124 are respectively arranged at the two ends of the bottom wall, and a charging terminal 133 is arranged on each boss 124. The two charging terminals 133 are respectively located at the two ends of the charging groove 121, and are symmetrically distributed. By arranging the charging terminals 133 symmetrically, there is no need to consider the front and rear direction problem when the wearable device 200 is placed. No matter which side of the base 110 the wearable device 200 enters from, effective electrical connection can be achieved and charging can be smoothly achieved. The top surface of the boss 124 is about 1mm to 2mm higher than the bottom wall. The provision of the boss 124 can facilitate the charging part of the wearable device 200 to contact the charging terminal 133 of the base 110 more conveniently, and the connection is more reliable. Optionally, an anti-slip part 127 is provided on the bottom wall between the two bosses 124. The anti-slip part 127 includes but is not limited to a plurality of small protrusions or anti-slip grooves arranged at intervals. The anti-slip part 127 is used to increase the friction between the base 110 and the wearable device 200 after contact, further preventing the base 110 and the wearable device 200 from sliding relative to each other, thereby improving connection reliability and charging stability.

[0054] Optionally, the structure of the charging terminal 133 can be a conductive column, a metal sheet, a charging probe, a charging contact or a charging spring pin. In this embodiment, the charging terminal 133 adopts a charging spring pin, one end of which is welded to the circuit board 131, and the other end passes through the first mounting through hole 123 of the boss 124 and exposes the top surface of the boss 124. The charging spring pin has a certain elasticity. When it is not subjected to external force, that is, when the charging spring pin is not in contact with the wearable device 200, the charging spring pin is in the original length state; when the wearable device 200 is placed in the charging groove 121, the charging spring pin is subjected to the pressure of the wearable device 200 and is in a contracted state. Setting the charging terminal 133 as a charging spring pin with a certain elasticity can prevent the rigid contact between the wearable device 200 and the charging terminal 133, has a certain buffering effect, reduces the wear of the wearable device 200 and the charging terminal 133, and is conducive to improving the service life of the wearable device 200 and the charging terminal 133.

[0055] Please refer to Figure 5, the first clamping member 140 and the second clamping member 150 are movably arranged on the base 110, so that the first clamping member 140 and the second clamping member 150 can move relative to the base 110, so as to realize that the first clamping member 140 and the second clamping member 150 are facing away from or close to each other, so as to clamp the wearable device 200 when the first clamping member 140 and the second clamping member 150 are close to each other, and release the wearable device 200 when the first clamping member 140 and the second clamping member 150 are facing away from each other. The movable connection mode includes but is not limited to the mode in which the first clamping member 140 and the second clamping member 150 rotate or translate relative to the base 110 respectively. In this embodiment, the first clamping member 140 and the second clamping member 150 are respectively connected to the base 110 for rotation, and further, the first clamping member 140 and the second clamping member 150 are respectively connected to the first shell 120 for rotation, or the first clamping member 140 and the second clamping member 150 are respectively connected to the second shell 130 for rotation. In this embodiment, the first clamping member 140 and the second clamping member 150 are respectively rotatably connected to the first housing 120. Optionally, an elastic member 128 is provided between at least one of the first clamping member 140 and the second clamping member 150 and the first housing 120, and the elastic member 128 is used to apply a force to bring the first clamping member 140 and the second clamping member 150 closer to each other.

[0056] Here, the first clamping member 140 and the first housing 120 are rotatably connected as an example. The first clamping member 140 and the first housing 120 can be rotatably connected by hinges or by a rotating shaft 1281. Optionally, the elastic member 128 is a torsion spring, a spring sheet or an elastic rope. In this embodiment, a rotating shaft 1281 is provided on the first housing 120, and the elastic member 128 is a torsion spring. The torsion spring is sleeved on the rotating shaft 1281, one end of the torsion spring abuts against the base 110, and the other end abuts against the first clamping member 140. Further, a supporting block 147 is provided on the side of the first clamping member 140 facing the second clamping member 150, and one end of the torsion spring abutting against the first clamping member 140 abuts against the supporting block 147; or, the number of the supporting blocks 147 on the first clamping member 140 is two, and the end of the torsion spring abuts between the two supporting blocks 147, and the two supporting blocks 147 play a limiting role on the end of the torsion spring.

[0057] Optionally, the rotating shaft 1281 is a pin, and a first fixing block 129 is provided on the long side of the first housing 120 close to the first clamping member 140, and a second fixing block 146 is provided on the side of the first clamping member 140 close to the second clamping member 150. A second mounting through hole 1291 is provided on the first fixing block 129, and a third mounting through hole 1461 is provided on the second fixing block 146. The pin passes through the second mounting through hole 1291 and the third mounting through hole 1461 at the same time. The torsion spring is sleeved on the pin and is located between the first fixing block 129 and the second fixing block 146, so as to realize the rotation connection between the first housing 120 and the first clamping member 140. In this embodiment, the number of the first fixing blocks 129 is two, and the number of the second fixing blocks 146 is three. After installation, the three second fixing blocks 146 are located between the two first fixing blocks 129, and the torsion spring is located between any two adjacent second fixing blocks 146. Of course, it is not limited to this. The number and installation position of the first fixing blocks 129, the number and installation position of the second fixing blocks 146, and the number and installation position of the torsion springs can be adjusted according to actual conditions and are not specifically limited here.

[0058] It is easy to understand that the rotational connection structure between the second clamping member 150 and the first housing 120 is the same as the rotational connection structure between the first clamping member 140 and the first housing 120, which will not be described in detail here. In other optional embodiments, the second housing 130 is rotationally connected to the first clamping member 140 and the second clamping member 150 respectively, and the specific rotational connection structure can also adopt the above structure, which will not be described in detail here.

[0059] The first clamping member 140 is provided with a first protrusion 141, which extends in a direction close to the second clamping member 150; the second clamping member 150 is provided with a second protrusion 151, which extends in a direction close to the first clamping member 140.

The first protrusion 141 and the second protrusion 151 are arranged opposite to each other, and are used to fix the wearable device 200 between the first protrusion 141, the second protrusion 151 and the base 110, that is, after the wearable device 200 is placed in the charging groove 121, the first protrusion 141 and the second protrusion 151 buckle the wearable device 200, further limit the position of the wearable device 200, and improve the connection reliability. Optionally, a side of the first clamping member 140 facing the second clamping member 150 is provided with an avoidance groove 143, and a side of the second clamping member 150 facing the first clamping member 140 is provided with an avoidance groove 143. The avoidance groove 143 is provided to prevent the first clamping member 140 and the second clamping member 150 from pressing the button 217 on the wearable device 200 to avoid misoperation. In addition, a side of the first clamping member 140 facing away from the second clamping member 150 and a side of the second clamping member 150 facing away from the first clamping member 140 are both provided with an anti-slip portion 155. The anti-slip portion 155 includes but is not limited to a plurality of small protrusions or anti-slip patterns arranged at intervals. In this embodiment, the anti-slip portions 155 on the first clamping member 140 and the second clamping member 150 use anti-slip patterns, which are not only beautiful, but also conducive to increasing friction, making it easy to take and put the charger 100.

[0060] It can be understood that the charger 100 is used to charge the wearable device 200, and its charging power source can be a dry cell battery, a lithium battery, etc. arranged on the base 110, or it can be an external power source connected. In this embodiment, the charger 100 also includes a power supply interface 170, and the power supply interface 170 is electrically connected to the circuit board 131. The power supply interface 170 is used to connect to the charging power source, and the power supply interface 170 can be a USB interface, a three-phase plug or a two-phase plug, etc. Further, in this embodiment, the power supply interface 170 is electrically connected to the circuit board 131 through the charging cable 160. One end of the charging cable 160 passes through the second shell 130 and is electrically connected to the circuit board 131, and the other end is provided with the power supply interface 170. The power supply interface 170 adopts the form of a USB interface, which is more convenient to use.

[0061] The charger 100 provided in this embodiment is provided with a charging groove 121 on the base 110 for placing the wearable device 200, which can effectively limit the position of the wearable device 200 and improve the connection reliability; the first clamping member 140 and the second clamping member 150 are arranged to rotate relative to the base 110, which can further limit the movement of the wearable device 200 in the width direction, that is, the short side direction of the first shell 120; the first convex block 141 and the second convex block 151 are arranged relatively to further limit the movement of the wearable device 200 in the height direction, thereby realizing the reliable positioning of the wearable device 200. By arranging a charging spring pin in the charging groove 121, a reliable electrical connection between the charger 100 and the wearable device 200 is realized, which is conducive to improving the connection reliability and charging stability of the charger 100 and the wearable device 200.
