That is, in this embodiment of the present application, by setting the charging member in the charging stand, and the control member 20 is electrically connected to the first charging contact 11 and the second charging contact 12, respectively, the charging stand can charge the electronic device 100 when the electronic device 100 is charged in the forward direction, and the charging stand can still charge the electronic device 100 when the electronic device 100 is charged in the reverse direction, so that the problem that the electronic device 100 cannot be charged when placed in the reverse direction is avoided.
It should be noted that, in the embodiment of the present application, the electronic device 100 includes, but is not limited to, a smart watch, a smart bracelet, and the like.
Additionally, in some embodiments, as shown in fig. 3, 5, and 8, the control member 20 may include a first input 21, a second input 22, a first output 23, a second output 24, and a control 25. The first input terminal 21 is used for inputting positive current, the second input terminal 22 is used for inputting negative current, the first output terminal 23 is electrically connected with the first charging contact 11, and the second output terminal 24 is electrically connected with the second charging contact 12.

Since the first input terminal 21 may input the positive current, the second input terminal may input the negative current, the first output terminal 23 is electrically connected to the first charging contact 11, and the second output terminal 24 is electrically connected to the second charging contact 12, the control terminal 25 may control the first input terminal 21 to be connected to the first output terminal 23, the second input terminal 22 to be connected to the second output terminal 24, or the first input terminal 21 to be connected to the second output terminal 24, and the second input terminal 22 to be connected to the first output terminal 23 according to different situations of the electronic device 100.
Specifically, in the case where the electronic device 100 is being charged in the forward direction, the positive charging contact 1001 of the electronic device 100 is in contact with the first output terminal 23, the negative charging contact 1002 of the electronic device 100 is in contact with the second output terminal 24, the control terminal 25 may be in the first state, the control terminal 25 controls the first input terminal 21 to be connected with the first output terminal 23, the second input terminal 22 is connected with the second output terminal 24, at this time, the charging wire 001 may transmit the positive current to the first input terminal 21, the negative current to the second input terminal 22, the first input terminal 21 may transmit the positive current to the first output terminal 23, the second input terminal 22 may transmit the negative current to the second output terminal 24, so that the first output terminal 23 may transmit the positive current to the positive charging contact 1001 of the electronic device 100, and the second output terminal 24 may transmit the negative current to the negative charging contact 1002 of the electronic device 100, so that the charging stand may charge the electronic device 100 in the forward direction. In the case of reverse charging of the electronic device 100, the positive charging contact 1001 of the electronic device 100 is in contact with the second output terminal 24, the negative charging contact 1002 of the electronic device 100 is in contact with the first output terminal 23, the control terminal 25 may be in the second state, the control terminal 25 controls the first input terminal 21 to be connected with the second output terminal 24, the second input terminal 22 is connected with the first output terminal 23, at this time, the charging wire 001 may transmit the positive current to the first input terminal 21, the negative current to the second input terminal 22, the first input terminal 21 may transmit the positive current to the second output terminal 24, the second input terminal 22 may transmit the negative current to the first output terminal 23, so that the first output terminal 23 may transmit the negative current to the negative charging contact 1002 of the electronic device 100, and the second output terminal 24 may transmit the positive current to the positive charging contact 1001 of the electronic device 100, so that the charging stand may charge the electronic device 100 when the electronic device 100 is reversely charged.
Additionally, in some embodiments, a charging interface may be provided on the housing 10, the charging interface having a positive contact electrically connected to the first input 21 and a negative contact electrically connected to the second input 22.
Since the charging interface is provided on the housing 10, the charging interface has the positive electrode contact and the negative electrode contact, and thus the charging interface can be inserted into the charging interface through the charging wire 001, so that the charging wire 001 is connected with the positive electrode contact and the negative electrode contact, respectively, so that the charging wire 001 can transmit electric energy to the charging stand, and the charging stand can charge the electronic device 100. In addition, since the positive electrode contact is electrically connected to the first input terminal 21 and the negative electrode contact is electrically connected to the second input terminal 22, the first input terminal 21 can be made to input a positive electrode current and the second input terminal 22 can be made to input a negative electrode current.
In addition, in some embodiments, as shown in fig. 3-8, the cradle may further include a circuit board 30, a resistor 40, and a conductive member 50. The circuit board 30 and the conductive member 50 are disposed in the housing 10, and the conductive member 50 is movable in the housing 10, and the circuit board 30 may be provided with the first contact 31 and the second contact 32 at intervals, and the conductive member 50 is used for conducting the first contact 31 and the second contact 32. The first contact 31 is electrically connected to the control terminal 25, the control terminal 25 is electrically connected to a first terminal of the resistor 40, a second terminal of the resistor 40 is grounded, and the second contact 32 is electrically connected to the positive contact. In the case where the electronic device 100 is being charged on the charging stand, the conductive member 50 is not in contact with both the first contact 31 and the second contact 32, and the control terminal 25 is in the first state. In the case where the electronic device 100 is charged in the charging stand in the reverse direction, the conductive member 50 is respectively in contact with the first contact 31 and the second contact 32, so that the first contact 31 and the second contact 32 are conducted, and the control terminal 25 is in the second state.
Since the conductive member 50 is movable in the housing 10, the circuit board 30 is provided with first contacts at intervals
31 and the second contact 32, so that the conductive member 50 can conduct the first contact 31, i.e., the conductive member 50 can be simultaneously contacted with the first contact 31 and the second contact 32, at which time the first contact 31 and the second contact 32 can be conducted through the conductive member 50. Since the first contact 31 is electrically connected to the control terminal 25, the first terminal of the resistor 40 of the control terminal 25 is electrically connected, and the second terminal of the resistor 40 is grounded, the control terminal 25 can be in a low-level state. Since the second contact 32 is electrically connected to the positive electrode contact, the control terminal 25 can be in a high-level state at this time when the first contact 31 and the second contact 32 are conducted through the conductive member 50.
Specifically, in the case where the electronic device 100 is charged positively on the charging stand, the conductive member 50 is not in contact with the first contact 31 and the second contact 32, and at this time, the control terminal 25 is grounded through the resistor 40, so that the control terminal 25 is in a low-level state, i.e., the control terminal 25 is in a first state, the first input terminal 21 is connected to the first output terminal 23, the second input terminal 22 is connected to the second output terminal 24, the first output terminal 23 outputs a positive current to the positive charging contact 1001 of the electronic device 100, and the second output terminal 24 outputs a negative current to the negative charging contact 1002 of the electronic device 100, so that the charging stand charges the electronic device 100. In the case that the electronic device 100 is charged in the reverse direction on the charging stand, the conductive member 50 is respectively in contact with the first contact 31 and the second contact 32, at this time, the first contact 31 and the second contact 32 are conducted through the conductive member 50, and the positive current in the charging wire 001 can be transferred to the conductive member 50 through the second contact 32, and transferred to the first contact 31 through the conductive member 50, and finally transferred to the control terminal 25, so that the control terminal 25 is in a high level state, i.e., the control terminal 25 is in a second state, the first input terminal 21 is connected with the second output terminal 24, the second input terminal 22 is connected with the first output terminal 23, the second output terminal 24 outputs the positive current to the positive charging contact 1001 of the electronic device 100, and the first output terminal outputs the negative current to the negative charging contact 1002 of the electronic device 100, so that the charging stand can charge the electronic device 100.
The circuit board 30 may be a printed circuit board 30 (Printed Circuit Board, PCB), and of course, may be a flexible circuit board 30 (Flexible Printed Circuit, FPC).
In addition, when the first contact 31 and the second contact 32 are not conductive, the resistor 40 may connect the control terminal 25 to the ground, so that the control terminal 25 is in a low level state, i.e., the control terminal 25 is in the first state; when the first contact 31 and the second contact 32 are conducted, at this time, the positive current is transferred to the conductive member 50 through the second contact 32 and transferred to the first contact 31 through the conductive member 50, where the positive current can be transferred to the control terminal 25, and the control terminal 25 is in a high level state, i.e., the control terminal 25 is in a second state, and the positive current can be transferred to the resistor 40, and at this time, the resistor 40 is also equivalent to a functional member, and when the positive current flows through the resistor 40, the resistor 40 heats up, so as to avoid the positive current flowing to the ground.
Additionally, in some embodiments, as shown in FIG. 3, conductive member 50 may include a conductive body 51, a first thimble 52, and a second thimble 53. The first thimble 52 and the second thimble 53 are arranged on the conductive main body 51 at intervals, the first thimble 52 is used for contacting with the first contact 31, and the second thimble 53 is used for contacting with the second contact 32. In the case where the electronic device 100 is being charged positively on the charging stand, the first ejector pin 52 is not in contact with the first contact 31, the second ejector pin 53 is not in contact with the second contact 32, and the control terminal 25 is in the first state; when the electronic device 100 is charged in the charging stand in the reverse direction, the first pin 52 contacts the first contact 31, the second pin 53 contacts the second contact 32, so that the first contact 31 and the second contact 32 are turned on, and the control terminal 25 is in the second state.
Because the first thimble 52 and the second thimble 53 are disposed on the conductive body 51 at intervals, when the conductive body 51 moves, the conductive body 51 can drive the first thimble 52 and the second thimble 53 to move, so that the first thimble 52 contacts the first contact 31, the second thimble 53 contacts the second contact 32, or the first thimble 52 is separated from the first contact 31, and the second thimble 53 is separated from the second contact 32.
Specifically, when the electronic device 100 is charged in the forward direction on the charging stand, the first pin 52 is not in contact with the first contact 31, the second pin 53 is not in contact with the second contact 32, and at this time, the control terminal 25 is grounded due to the resistor 40, the control terminal 25 is in a low-level state, i.e., the control terminal 25 is in the first state, the first output terminal 23 outputs the positive current, and the second output terminal 24 outputs the negative current. In the case of the electronic device 100 being charged in the reverse direction on the charging stand, the first ejector pin 52 is in contact with the first contact 31, the second ejector pin 53 is in contact with the second contact 32, at this time, the positive current may be transferred to the second contact 32, then transferred to the second ejector pin 53, transferred to the conductive body 51 through the second ejector pin 53, then transferred to the first ejector pin 52, transferred to the first contact 31 through the first ejector pin 52, and transferred to the control terminal 25 through the first contact 31, so that the control terminal 25 is in the high state, i.e., the control terminal 25 is in the second state, the first output terminal 23 outputs the negative current, and the second output terminal 24 outputs the positive current.
The material of the conductive body 51 may be a metal material, and the material of the first thimble 52 and the second thimble 53 may be a metal material.
In addition, in the embodiment of the present application, the manner in which the conductive member 50 is movable in the housing 10 may be different, specifically, the following are described as examples:
mode (1)
As shown in fig. 3, 4, 6 and 7, the charging stand may further include a first magnetic member 60 and an elastic member 70. The inner wall of the shell 10 is provided with a blocking piece 13, the first magnetic piece 60 is connected with one end of the elastic piece 70, and the other end of the elastic piece 70 is fixed on the blocking piece 13; the conductive member 50 is connected to the first magnetic member 60. The electronic device 100 is provided with a second magnetic member 110, and the magnetism of the first magnetic member 60 is the same as that of the second magnetic member 110. In the case that the electronic device 100 is being charged positively on the charging stand, the first magnetic member 60 and the second magnetic member 110 are dislocated from each other, the elastic member 70 is in the initial state, the first magnetic member 60 is in the first position, and the conductive member 50 is not in contact with both the first contact 31 and the second contact 32. In the case of the electronic device 100 being charged in the charging stand in the reverse direction, the first magnetic member 60 is located opposite to the second magnetic member 110, the elastic member 70 is in a compressed state, the first magnetic member 60 is in the second position, and the conductive member 50 is in contact with the first contact 31 and the second contact 32, respectively.
Since the blocking member 13 is disposed on the inner wall of the housing 10, the first magnetic member 60 is connected to one end of the elastic member 70, and the other end of the elastic member 70 is fixed on the blocking member 13, when the first magnetic member 60 is stressed, the first magnetic member 60 can apply a force to the elastic member 70, so that the state of the elastic member 70 is changed. In addition, since the second magnetic element 110 is disposed in the electronic device 100, and the magnetism of the first magnetic element 60 is the same as that of the second magnetic element 110, when the first magnetic element 60 and the second magnetic element 110 are opposite, the second magnetic element 110 and the first magnetic element 60 can repel each other, so that the first magnetic element 60 is stressed, and the first magnetic element 60 is further moved, so that the state of the elastic element 70 is changed.
Specifically, when the electronic device 100 is charged positively on the charging stand, the first magnetic element 60 and the second magnetic element 110 are offset from each other, at this time, the first magnetic element 60 and the second magnetic element 110 will not apply force to each other, so that the initial position of the first magnetic element 60 remains unchanged, that is, the first magnetic element 60 is in the first position, the elastic element 70 is in the initial state, the conductive element 50 is not in contact with the first contact 31 and the second contact 32, so that the first contact 31 is not in conduction with the second contact 32, and the control terminal 25 is in the first state, the first output terminal 23 outputs the positive current, and the second output terminal 24 outputs the negative current. Under the condition that the electronic device 100 is reversely charged on the charging stand, the second magnetic element 110 is opposite to the first magnetic element 60, at this time, the first magnetic element 60 and the second magnetic element 110 repel each other, that is, the first magnetic element 60 and the second magnetic element 110 apply force to each other, so that the first magnetic element 60 moves, that is, the first magnetic element 60 compresses the elastic element 70, so that the elastic element 70 is in a compressed state, and the first magnetic element 60 is in the second position, the first magnetic element 60 drives the conductive element 50 to move, so that the conductive element 50 contacts the first contact 31 and the second contact 32 respectively, so that the first contact 31 is conducted with the second contact 32, and the control end 25 is in the second state, the first output end 23 outputs a negative current, and the second output end 24 outputs a positive current.
When the conductive member 50 includes the conductive body 51, the first thimble 52, and the second thimble 53, the conductive body 51 is connected to the first magnetic member 60 when the conductive member 50 is connected to the first magnetic member 60. In addition, the elastic member 70 may be in a compressed state or in a natural extended state in an initial state.
Additionally, in some embodiments, as shown in fig. 3, 4, 6, and 7, the cradle may also include a stand-off 80. The support 80 is disposed in the housing 10, and the support 80 is provided with a receiving groove in which the first magnetic member 60 is located. The opposite surfaces of the support 80 and the receiving groove are connected to one end of the elastic member 70 and the conductive member 50, respectively.
Since the support 80 is provided with the accommodating groove, the first magnetic member 60 is located in the accommodating groove, and the opposite surfaces of the support 80 and the accommodating groove are respectively connected with one end of the elastic member 70 and the conductive member 50, when the second magnetic member 110 is opposite to the first magnetic member 60, at this time, the first magnetic member 60 is subjected to the repulsive force of the second magnetic member 110, so that the first magnetic member 60 applies a force to the support 80, so that the support 80 compresses the elastic member 70, and the support 80 drives the conductive member 50 to move, so that the conductive member 50 contacts the first contact 31 and the second contact 32 respectively. In addition, by providing the support 80, the first magnetic member 60 can be connected with the conductive member 50 through the support 80, so that the first magnetic member 60 is prevented from being directly connected with the conductive member 50, and the first magnetic member can magnetize the conductive member 50.
The first magnetic member 60 may be disposed in the accommodating groove by bonding, that is, the first magnetic member 60 is bonded to the groove bottom or the groove wall of the accommodating groove by the bonding member. Of course, the first magnetic member 60 may also be clamped in the accommodating groove. The embodiment of the present application is not limited herein as to the manner in which the first magnetic member 60 is disposed in the receiving groove.
In addition, the support 80 may be made of a non-metal material, such as plastic, and the embodiment of the present application is not limited herein with respect to the specific material of the support 80.
Mode (2)
As shown in fig. 9 and only in fig. 12, the cradle may further include a motor 90. The motor 90 is disposed in the housing 10, and the electrode is connected to the conductive member 50, and the motor 90 is used for driving the conductive member 50 to move. In the case where the electronic device 100 is being charged on the charging stand, the motor 90 drives the conductive member 50 to be out of contact with both the first contact 31 and the second contact 32. In the case where the electronic device 100 is charged in the reverse direction on the charging stand, the motor 90 drives the conductive member 50 to be in contact with the first contact 31 and the second contact 32, respectively.
When the motor 90 is disposed in the housing 10 and the motor 90 is connected to the conductive member 50, the motor 90 may drive the conductive member 50 to move so that the conductive member 50 contacts the first contact 31 and the second contact 32, respectively, i.e., the first contact 31 is electrically connected to the second contact 32, or the conductive member 50 is separated from the first contact 31 and the second contact 32, i.e., the first contact 31 is electrically disconnected from the second contact 32.
Specifically, in the case where the electronic device 100 is charged positively on the charging stand, the motor 90 may drive the conductive element 50 to remain at the initial position, or drive the conductive element 50 away from the initial position, so that the conductive element 50 is not contacted with the first contact 31 and the second contact 32, i.e. the first contact 31 is not conducted with the second contact 32, and the control terminal 25 is in the first state, the first output terminal 23 outputs the positive current, and the second output terminal 24 outputs the negative current. In the case of the electronic device 100 being charged in the reverse direction on the charging stand, the motor 90 may drive the conductive member 50 to approach the first contact 31 and the second contact 32, and make the conductive member 50 contact the first contact 31 and the second contact 32, i.e. the first contact 31 is conducted with the second contact 32, so that the control terminal 25 is in the second state, the first output terminal 23 outputs the negative current, and the second output terminal 24 outputs the positive current.
Additionally, in some embodiments, as shown in fig. 9 or 10, the motor 90 may be connected to the conductive member 50 in the following manner: the output shaft of the motor 90 is connected with a screw rod 91, a slide block 92 is arranged on the screw rod 91, and the slide block 92 is connected with the conductive member 50.
When the output shaft of the motor 90 is connected with the screw 91, the screw 91 is provided with the slide block 92, and the slide block 92 is connected with the conductive member 50, at this time, when the output shaft of the motor 90 rotates, the output shaft drives the screw 91 to rotate, so that the slide block 92 moves on the screw 91 along the axial direction of the screw 91, that is, through the screw 91 and the slide block 92, the rotation motion of the screw 91 can be converted into the linear motion of the slide block 92, so that the slide block 92 moves along the axial direction of the screw 91. When the slider 92 moves, the slider 92 drives the conductive element 50 to move, so that the conductive element 50 approaches or moves away from the first contact 31 and the second contact 32, and the first contact 31 is conducted or not conducted with the second contact 32. Specifically, in the case where the electronic device 100 is being charged on the charging stand, the motor 90 may not be operated, so that the slider 92 is kept stationary, and thus the conductive member 50 is kept stationary, so that the first contact 31 is not conducted with the second contact 32. Alternatively, the output shaft of the motor 90 may be rotated in a first direction such that the slider 92 is away from the first contact 31 and the second contact 32, and further such that the conductive member 50 is away from the first contact 31 and the second contact 32 such that the first contact 31 is non-conductive with the second contact 32. In the case of reverse charging of the electronic device 100 on the charging stand, the output shaft of the motor 90 may rotate in the second direction, such that the slider 92 approaches the first contact 31 and the second contact 32, and further such that the conductive member 50 approaches the first contact 31 and the second contact 32, such that the first contact 31 and the second contact 32 are conductive.
The first direction may be a clockwise direction, and the second direction is a counterclockwise direction. Of course, the first direction may be a counterclockwise direction, and the second direction is a clockwise direction.
When the conductive member 50 includes the conductive body 51, the slider 92 is connected to the conductive body 51.
In addition, in some embodiments, as shown in fig. 9 to 12, a controller 101 and a sensor 102 may be provided in the cradle, and a member 120 to be detected is provided in the electronic apparatus 100. The controller 101 is electrically connected with the sensor 102, and the controller 101 is electrically connected with the motor 90, and the sensor 102 is used for detecting the member 120 to be detected. Under the condition that the electronic device 100 is positively charged on the charging seat, the sensor 102 and the to-be-detected piece 120 are staggered, the sensor 102 cannot sense the to-be-detected piece 120, and the controller 101 controls the motor 90 to drive the conductive piece 50 to be not contacted with the first contact 31 and the second contact 32; under the condition that the electronic device 100 is charged reversely on the charging stand, the sensor 102 is opposite to the to-be-detected piece 120, the sensor 102 senses the to-be-detected piece 120, and the controller 101 controls the motor 90 to drive the conductive piece 50 to be contacted with the first contact 31 and the second contact 32 respectively.
Since the controller 101 is electrically connected to the sensor 102 and the motor 90, respectively, the sensor 102 can transmit detection information to the control, and the controller 101 can control the motor 90 according to the detection information, so that the motor 90 can drive the conductive member 50 to move, thereby enabling the conductive member 50 to be in contact with the first contact 31 and the second contact 32, respectively, or enabling the conductive member 50 to be out of contact with the first contact 31 and the second contact 32, respectively. Since the member to be detected 120 is provided in the electronic device 100, the sensor 102 can detect the member to be detected 120 when the electronic device 100 is charged on the charging stand, so that the sensor 102 can transmit detection information to the controller 101.
Specifically, in the case where the electronic device 100 is charged positively on the charging stand, the sensor 102 and the member to be detected 120 are dislocated from each other, at this time, the sensor 102 senses that the member to be detected 120 is not sensed, the controller 101 controls the conductive member 50 to be away from the first contact 31 and the second contact 32, so that the conductive member 50 is not contacted with the first contact 31 and the second contact 32, or the controller 101 controls the conductive member 50 to be kept at the current position, so that the conductive member 50 is not contacted with the first contact 31 and the second contact 32, so that the control terminal 25 is in the first state, the first output terminal 23 outputs the positive current, and the second output terminal 24 outputs the negative current. Under the condition that the electronic device 100 is charged reversely on the charging seat, the sensor 102 is opposite to the to-be-detected piece 120, at this time, the sensor 102 senses the to-be-detected piece 120, the sensor 102 can send detection information to the controller 101, the controller 101 controls the motor 90 to drive the conductive piece 50 to approach the first contact 31 and the second contact 32 according to the detection information, so that the conductive piece 50 contacts the first contact 31 and the second contact 32 respectively, and the first contact 31 and the second contact 32 are conducted, so that the control end 25 is in the second state, the first output end 23 outputs the negative current, and the second output end 24 outputs the positive current.
It should be noted that, the member to be detected 120 may be a magnetic member, and in this case, the sensor 102 may be a hall sensor 102. Of course, the magnetic member may be other devices that facilitate detection, and the sensor 102 may be specifically changed according to the type of the member 120 to be detected, which is not limited herein.
In the embodiment of the present application, since the control member 20 is electrically connected to the first charging contact 11 and the second charging contact 12, respectively, the control member 20 can control the current of the first charging contact 11 and the second charging contact 12. Specifically, in the case where the electronic device 100 is being charged on the charging stand in the forward direction, the positive charging contact 1001 of the electronic device 100 is in contact with the first charging, the negative charging contact 1002 of the electronic device 100 is in contact with the second charging contact 12, the control member 20 controls the first charging contact 11 to output the positive current, and the second charging contact 12 to output the negative current, so that the charging stand can charge the electronic device 100; in the case that the electronic device 100 is reversely charged on the charging stand, the positive charging contact 1001 of the electronic device 100 is in contact with the second charging, the negative charging contact 1002 of the electronic device 100 is in contact with the first charging contact 11, the control member 20 controls the first charging contact 11 to output the negative current, and the second charging contact 12 outputs the positive current, so that the charging stand can still charge the electronic device 100. That is, in this embodiment of the present application, by setting the charging member in the charging stand, and the control member 20 is electrically connected to the first charging contact 11 and the second charging contact 12, respectively, the charging stand can charge the electronic device 100 when the electronic device 100 is charged in the forward direction, and the charging stand can still charge the electronic device 100 when the electronic device 100 is charged in the reverse direction, so that the problem that the electronic device 100 cannot be charged when placed in the reverse direction is avoided.
