[0044] Example

[0045] See Figure 1-Figure 2 In this embodiment, a battery with a conductive and restraining structure is provided, including a conductive member 100, a detection device 200, and a control module 300. The conductive member 100 is electrically connected to a power supply device 20 or a power-consuming device. The power supply device 20 is used to provide electrical energy to charge the battery 10, and the power-consuming device is used to obtain the electrical energy provided by the battery 10. Only the power supply device 20 is shown in the figures.

[0046] The conductive member 100 can be made of conductive materials such as copper and silver. The power supply device 20 may include a power grid and a conversion device, including a rectifier and a transformer. The conversion device can convert the alternating current (AC) transmitted by the power grid into direct current (DC) of a corresponding voltage, thereby charging the battery 10. The power-consuming device may include electrical appliances, etc.

[0047] like Figure 3-Figure 5 As shown, in this embodiment, a restraining member 400 is provided on the conductive member 100. It should be noted that, in order to facilitate observation Figure 4 and Figure 5 The battery 10 is not shown. The restraint 400 has a restrained state and a released state:

[0048] When in the restrained state, the restraining member 400 is used to apply a restraining force to the conductive member 100 so that the conductive member 100 is electrically connected to the terminal of the battery 10 and the conductive member 100 is fixedly connected to the terminal of the battery 10; at this time, the conductive member 100 and the battery 10 are in a relatively fixed state;

[0049] When in the released state, the restraint 400 is used to release the restraining force applied to the conductive member 100, so that the conductive member 100 is electrically separated from the pole, and the conductive member 100 loosens the pole so that the battery 10 can move; at this time, the conductive member 100 and the pole are no longer electrically connected, thereby stopping the battery 10 from charging and discharging, and since the battery 10 is movable, the user can remove the battery 10.

[0050] The battery 10 has two electrodes, which are named as a first electrode 11 and a second electrode 12 for convenience of description. Among them, one of the first electrode 11 and the second electrode 12 is a positive electrode and the other is a negative electrode. For convenience of description, the first electrode 11 is set as the positive electrode and the second electrode 12 is set as the negative electrode.

[0051] like Figure 1As shown, in this embodiment, the conductive member 100 is disposed on the first pole 11. Specifically, the first pole 11 corresponds to the conductive member 100, and the second pole 12 corresponds to the conductor 500. During charging, the conductive member 100 is connected to the positive electrode of the power supply device 20, and the conductor 500 is connected to the negative electrode of the power supply device 20. During discharging, the conductive member 100 is connected to the positive electrode of the power consumption device, and the conductor 500 is connected to the negative electrode of the power consumption device. The conductor 500 can be made of a metal sheet, etc.

[0052] like Figure 7 As shown, in other embodiments, the first pole 11 and the second pole 12 are both provided with a conductive member 100 .

[0053] During the charging and discharging process of the battery 10, the first terminal 11 is electrically connected to the conductive member 100, and the second terminal 12 is electrically connected to the conductor 500. When the restraining member 400 is in the released state, the conductive member 100 and the first terminal 11 are separated. At this time, the conductive member 100 and the first terminal 11 are no longer electrically connected, thereby automatically stopping the charging and discharging of the battery 10.

[0054] In this embodiment, both the detection device 200 and the restraint 400 are electrically connected to the control module 300. The detection device 200 is used to detect parameter information during the charging and discharging of the battery 10. The control module 300 is used to send a control signal to the restraint 400 when the parameter information is abnormal. The restraint 400 is used to switch from a restrained state to a released state upon receiving the control signal.

[0055] In some embodiments, the detection device 200 includes a temperature detection module, wherein the parameter information includes temperature. The temperature detection module includes a temperature sensor. During the charge and discharge process of the battery 10, if the temperature detection module detects that the temperature of the battery 10 exceeds a preset temperature, it indicates that the battery 10 has an abnormality. At this time, the control module 300 will send a control signal to the restraint 400, thereby separating the conductive member 100 from the first electrode 11, thereby automatically stopping the charge and discharge of the battery 10.

[0056] In some embodiments, the detection device 200 includes a current detection module, wherein the parameter information includes current. The current detection module includes a current sensor. During the charge and discharge process of the battery 10, when the current detection module detects that the current of the battery 10 exceeds a preset current, it indicates that the battery 10 has an abnormality. At this time, the control module 300 sends a control signal to the restraining member 400, thereby separating the conductive member 100 from the first electrode 11, thereby automatically stopping the charge and discharge of the battery 10.

[0057] In some embodiments, the detection device 200 includes a temperature detection module and a current detection module. When the information detected by either the temperature detection module or the current detection module is abnormal, the control module 300 will send a control signal to the restraint member 400, thereby separating the conductive member 100 from the first pole 11, thereby automatically stopping the charging and discharging of the battery 10.

[0058] The control module 300 may include a single chip microcomputer, a microprocessor, etc.

[0059] like Figure 5 As shown, the conductive member 100 includes a first clamping arm 110 and a second clamping arm 120. The two ends of the restraining member 400 are connected to the first clamping arm 110 and the second clamping arm 120, respectively. In this embodiment, the first clamping arm 110 and the second clamping arm 120 are separated from the terminal, indicating that the first clamping arm 110 and the second clamping arm 120 are electrically separated from the terminal and the first clamping arm 110 and the second clamping arm 120 are released from the terminal.

[0060] When the restraining member 400 is in the restraining state, the first pole 11 is clamped between the first clamping arm 110 and the second clamping arm 120 , and both the first clamping arm 110 and the second clamping arm 120 are in electrical contact with the first pole 11 ;

[0061] When the restraining member 400 is in the released state, the first clamping arm 110 and the second clamping arm 120 are electrically separated from the first pole 11, and the first clamping arm 110 and the second clamping arm 120 release the first pole 11. As a result, the conductive member 100 is electrically disconnected from the first pole 11, and the conductive member 100 releases the first pole 11.

[0062] The conductive member 100 can be connected to a fixing member. When the restraining member 400 is in the released state, the restraining member 400 is disconnected from the first pole 11. At this time, the fixing member can connect the restraining member 400, thereby preventing the restraining member 400 from falling. The restraining member 400 can be connected to the fixing member by a rope, etc. It should be noted that the fixing member is not shown in the drawings. The fixing member can be in the form of a strip, column, plate, etc.

[0063] The first clamping arm 110 includes a first connecting end 111 and a first free end 112 , and the second clamping arm 120 includes a second connecting end 121 and a second free end 122 .

[0064] The restraining member 400 includes a first mounting portion 410 and a second mounting portion 420 . The first mounting portion 410 is used to connect to the first free end 112 , and the second mounting portion 420 is used to connect to the second free end 122 .

[0065] When the restraining member 400 is in the restraining state, the first mounting portion 410 and the second mounting portion 420 are connected;

[0066] When the restraining member 400 is in the released state, the first mounting portion 410 is disconnected from the second mounting portion 420 .

[0067] Both the first mounting portion 410 and the second mounting portion 420 can be insulating members. For example, the first mounting portion 410 and the second mounting portion 420 can be made of a non-conductive material such as plastic. The first mounting portion 410 and the first free end 112, and the second mounting portion 420 and the second free end 122, can be secured by welding, clamping, or gluing.

[0068] Furthermore, the conductive member 100 further includes a connecting portion 130, to which the first connecting end 111 and the second connecting end 121 are both connected. The connecting portion 130 is configured to apply a force to the first clamping arm 110 and the second clamping arm 120 when the restraining member 400 is in the released state, thereby separating the first clamping arm 110 and the second clamping arm 120 from the first pole 11.

[0069] The connecting portion 130 is elastic and is used to provide elastic force to the first clamping arm 110 and the second clamping arm 120 when the restraining member 400 is in the released state, so as to separate the first clamping arm 110 and the second clamping arm 120 from the first pole 11 .

[0070] In this embodiment, the conductive member 100 can be made of an elastic conductive material. The first clamp arm 110, the connecting portion 130, and the second clamp arm 120 are connected in sequence and formed in one piece. When the restraining member 400 is in the restraining state, the restraining member 400 applies a restraining force to the first clamp arm 110 and the second clamp arm 120, so that the first pole 11 is clamped between the first clamp arm 110 and the second clamp arm 120. At this time, the connecting portion 130 is in a deformed state; when the restraining force disappears, the connecting portion 130, under the action of its own elastic force, causes the first clamp arm 110 and the second clamp arm 120 to move, thereby separating the first clamp arm 110 and the second clamp arm 120 from the first pole 11.

[0071] In other embodiments, the conductive member 100 includes a torsion spring. One end of the torsion spring is fixedly connected to the first clamping arm 110, and the other end is fixedly connected to the second clamping arm 120. When the restraining member 400 is in the restraining state, the restraining member 400 applies a restraining force to the first clamping arm 110 and the second clamping arm 120, so that the first pole 11 is clamped between the first clamping arm 110 and the second clamping arm 120. At this time, the torsion spring is in a deformed state. When the restraining force disappears, the torsion spring, under the action of its own elastic force, causes the first clamping arm 110 and the second clamping arm 120 to move, thereby separating the first clamping arm 110 and the second clamping arm 120 from the first pole 11.

[0072] like Figure 4As shown, in this embodiment, the restraining member 400 includes a fusible connecting section 430 . Specifically, the connecting section 430 can be a fuse.

[0073] When the connecting section 430 is not melted, the restraining member 400 is in a restrained state. At this time, the first mounting portion 410, the connecting section 430 and the second mounting portion 420 are connected in sequence, wherein the first mounting portion 410 and the second mounting portion 420 are connected through the connecting end.

[0074] When the connecting section 430 receives the control signal, it will be energized and melted. After the connecting section 430 is energized and melted, the restraining member 400 is in a released state, wherein the first mounting portion 410 and the second mounting portion 420 are disconnected, and the restraining force applied by the restraining member 400 to the conductive member 100 disappears.

[0075] like Figure 6 As shown, in other embodiments, the restraining member 400 includes an electromagnet 441. One of the first mounting portion 410 and the second mounting portion 420 is fixedly connected to the electromagnet 441, and the other is fixedly provided with a magnetic conductive member 442. The magnetic conductive member 442 is made of a material that can be attracted by a magnet.

[0076] When the electromagnet 441 is energized and the restraining member 400 is in a restrained state, the electromagnet 441 and the magnetic conductive member 442 are magnetically attracted to each other. At this time, the first mounting portion 410 and the second mounting portion 420 are connected through the magnetic attraction between the magnetic conductive member 442 and the electromagnet 441 .

[0077] When the electromagnet 441 receives the control signal, it is de-energized and de-magnetized. After the electromagnet 441 is de-energized and de-magnetized, the restraining member 400 is released. The electromagnet 441 is disconnected from the magnetic conductive member 442, and accordingly, the first mounting portion 410 is disconnected from the second mounting portion 420. Simultaneously, the restraining force exerted by the restraining member 400 on the conductive member 100 is eliminated.

[0078] Since the first mounting portion 410 and the second mounting portion 420 are both insulating members, the switching of the current on the conductive member 100 will not affect the restraining member 400 . Correspondingly, the switching of the current on the restraining member 400 will not affect the charging and discharging of the battery 10 .

[0079] In this embodiment, both the first and second poles 11 and 12 are columnar structures. A recessed portion 101 is provided on each of the first and second clamping arms 110 and 120, and the recessed portion 101 corresponds to the first pole 11. When the restraining member 400 is in the restrained state, the recessed portion 101 can conform to the surface of the first pole 11, thereby achieving surface contact between the first and second clamping arms 110 and 120 and the first pole 11, and achieving a closer fit.

[0080] The first clamping arm 110 and the second clamping arm 120 each include a first surface 102 and a second surface 103 disposed opposite each other. The first surface 102 is configured to electrically contact the first terminal 11 when the restraining member 400 is in the restrained state. The second surface 103 is provided with an insulating layer 104, which provides insulation to prevent accidents caused by fingers or other objects accidentally touching the conductive member 100 during the charging and discharging process of the battery 10.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
