[0002] Existing small energy storage batteries often use natural air cooling for heat dissipation, which has low heat dissipation efficiency. During the charging process of electronic devices, it is easy for the heat of the power supply to fail to dissipate in time, causing the energy storage power supply to overload, thereby causing damage to the equipment used.

[0003] In addition, in order to prevent damage to the equipment being used, current energy storage batteries generally have protection measures. When the temperature of the energy storage battery is too high, the connection between the energy storage battery and the equipment being used will be automatically cut off. However, current protection measures generally use electronic components for protection, such as temperature sensors or fuses. When the electronic components fail, the power supply cannot be cut off in time, and there is a risk of instability. Utility Model Content

DETAILED DESCRIPTION

[0032] The utility model is further described in conjunction with the following embodiments.

[0033] Depend on Figures 1 to 8 It can be seen that the safe and reliable energy storage battery described in this embodiment includes a housing 1; a battery pack 11 and a first heat dissipation liquid capsule 21 are arranged in the housing 1; the first heat dissipation liquid capsule 21 abuts against the bottom of the battery pack 11;

[0034] The housing 1 is provided with an output interface 3; the output interface 3 is provided with a metal contact sheet 31; a movable seat 4 is movably provided in the housing 1; the movable seat 4 is provided with a metal contact terminal 41 matched with the metal contact sheet 31; the metal contact terminal 41 is electrically connected to the battery pack 11;

[0035] A trigger assembly is disposed in the housing 1 ; after the first heat dissipation liquid capsule 21 expands due to heat, the first heat dissipation liquid capsule 21 drives the movable seat 4 to move through the trigger assembly, thereby separating the metal contact terminal 41 from the metal contact sheet 31 .

[0036] Specifically, in the safe and reliable energy storage battery described in this embodiment, when the temperature of the shell 1 is low, the volume of the first heat dissipation liquid capsule 21 is small, and at this time the metal contact sheet 31 is in contact with the metal contact terminal 41, so that the battery pack 11 can normally output power at the output interface 3 to supply power to the device, and the first heat dissipation liquid capsule 21 can cool the battery pack 11;

[0037] When the heat of the battery pack 11 is serious and the temperature of the shell 1 exceeds the threshold, the first heat dissipation liquid capsule 21 expands to a certain volume due to the heat. The first heat dissipation liquid capsule 21 drives the movable seat 4 to move through the trigger component, so that the metal contact terminal 41 is separated from the metal contact sheet 31. At this time, the battery pack 11 cannot supply power to the device, thereby cutting off the power supply, which can protect the energy storage battery and the device.

[0038] In the safe and reliable energy storage battery described in this embodiment, the first circuit board and the second circuit board are respectively provided at both ends of the housing 1; the first circuit board and the second circuit board are respectively detachably connected at both ends of the battery pack 11; the first circuit board and the second circuit board are respectively electrically connected to the metal contact terminals 41. Specifically, the above arrangement facilitates the replacement of the battery pack 11.

[0039] In the safe and reliable energy storage battery described in this embodiment, the housing 1 is provided with a second heat dissipation bladder 22, which abuts against the top of the battery pack 11. Specifically, the heat dissipation effect of the battery pack 11 can be further enhanced through the above arrangement.

[0040] In the safe and reliable energy storage battery described in this embodiment, volatile liquid is provided in both the first heat dissipation liquid capsule 21 and the second heat dissipation liquid capsule 22. Specifically, the volatile liquid can be water or ethanol, and when the temperature is high, the volatile liquid evaporates into gaseous state, so that the volume of the first heat dissipation liquid capsule 21 increases; when the temperature decreases, the volatile liquid liquefies into liquid state again, so that the volume of the first heat dissipation liquid capsule 21 decreases.

[0041] In the embodiment of the present invention, a safe and reliable energy storage battery is provided, wherein the movable seat 4 comprises a guide seat 5 provided on the housing 1 and a trigger seat 6 provided on the top of the first heat dissipation liquid capsule 21; the trigger seat 6 is provided in the housing 1 for lifting and movement; the movable seat 4 is provided on the trigger seat 6 for sliding in the horizontal direction. In the embodiment of the present invention, a safe and reliable energy storage battery is provided, wherein the movable seat 4 is provided with a driving pin 42; the guide seat 5 is provided with a driving slot; the driving pin 42 is provided in the driving slot for movement; the driving slot comprises a vertical slot 71, a horizontal slot 72 and an oblique slot 73 connected in sequence; the horizontal slot 72 is connected to the top of the vertical slot 71; the oblique slot 73 is connected to the bottom of the vertical slot 71; the depth of the vertical slot 71 is greater than the depth of the oblique slot 73; when the driving pin 42 moves in the vertical slot 71, the metal contact sheet 31 abuts against the metal contact terminal 41; when the driving pin 42 moves in the horizontal slot 72, the metal contact sheet 31 is separated from the metal contact terminal 41. In the embodiment of the present invention, a first spring 51 is provided between the movable seat 4 and the guide seat 5. In the safe and reliable energy storage battery described in this embodiment, a second spring 61 is provided between the housing 1 and the top of the trigger seat 6 .

[0042] Specifically, the safe and reliable energy storage battery described in this embodiment, when the temperature of the battery pack 11 is low, such as Figure 5 As shown, the volume of the first heat dissipation liquid bag 21 is relatively small. Under the action of the second spring 61, the trigger seat 6 and the movable seat 4 are located at the lower position. At this time, the driving pin 42 is located at the bottom of the vertical groove 71, and because the depth of the vertical groove 71 is greater than the depth of the oblique groove 73, the driving pin 42 cannot enter the oblique groove 73. At this time, the distance between the movable seat 4 and the guide seat 5 is relatively small. At this time, the metal contact sheet 31 is in contact with the metal contact terminal 41, so that the battery pack 11 can normally output power at the output interface 3 to power the device.

[0043] When the temperature of the battery pack 11 rises, the volume of the first heat dissipation liquid capsule 21 gradually increases, so that the trigger seat 6 gradually overcomes the effect of the second spring 61 and drives the movable seat 4 to move upward, so that the driving pin 42 gradually moves upward in the vertical groove 71; when the temperature of the battery pack 11 reaches the threshold, the volume of the first heat dissipation liquid capsule 21 reaches the threshold, and the driving pin 42 moves to the top of the vertical groove 71. Under the action of the first spring 51, the driving pin 42 moves to the other end of the transverse groove 72 away from the vertical groove 71, forming a state as shown in FIG. Figure 6 and Figure 7 The state shown; at this time, the distance between the movable seat 4 and the guide seat 5 is large, and the metal contact sheet 31 is separated from the metal contact terminal 41, so that the metal contact terminal 41 is separated from the metal contact sheet 31. At this time, the battery pack 11 cannot supply power to the device, thereby cutting off the power supply, which can protect the energy storage battery and the device.

[0044] When the temperature of the battery pack 11 decreases, the volume of the first heat dissipation liquid bag 21 gradually decreases. Under the action of the first spring 51, the driving pin 42 gradually descends along the inclined groove 73. When the driving pin 42 falls back into the bottom of the vertical groove 71, the metal contact terminal 41 contacts the metal contact sheet 31 again.

[0045] In the safe and reliable energy storage battery described in this embodiment, an inclined surface 74 is provided between the vertical groove 71 and the horizontal groove 72. Through the above arrangement, it is convenient for the driving pin 42 to move from the vertical groove 71 to the horizontal groove 72.

[0046] In the safe and reliable energy storage battery described in this embodiment, the housing 1 is provided with a guide groove 12; the trigger seat 6 is provided with a guide block 62 that matches the guide groove 12. The above arrangement enables the trigger seat 6 to perform a stable lifting movement.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
