[0002] As people engage in more and more outdoor activities, the occasions and demands for using mobile electronic devices are also increasing. However, these mobile electronic devices cannot be used outdoors for a long time due to battery capacity limitations. In order to ensure normal use, mobile energy storage battery packs or mobile energy storage battery boxes are needed.

[0003] The existing Chinese patent application number 202320127820.1 discloses an energy storage battery box, which relates to the field of battery box technology, including an energy storage box body and a box cover, wherein the box cover is located at the top of the energy storage box body, and installation bins are symmetrically arranged on both sides of the energy storage box body, and the installation bins extend to the inner cavity of the energy storage box body, and the inner cavity of the installation bins is fixedly connected with a cooling fan. The energy storage battery box provided by the utility model can actively extract the heat in the inner cavity of the energy storage box body from the energy storage box body in a timely manner by starting the cooling fans on both sides of the energy storage box body, thereby accelerating the heat dissipation of the energy storage box body. When the battery in the energy storage box body is continuously used and emits a large amount of heat, the fan and the semiconductor refrigeration sheet can be started to extract the cold air in the operating bin and discharge it into the inner cavity of the energy storage box body, thereby dissipating the heat in the inner cavity of the energy storage box body, and then cooperate with the cooling fans on both sides of the energy storage box body to achieve a better cooling and heat dissipation effect.

[0004] The energy storage battery box still has some shortcomings in actual use. It has poor air tightness, cannot avoid the influence of the external environment, and the heat conduction capacity in the battery box is average. At the same time, no explosion-proof components are set. Once the energy storage battery pack in the battery box is overused and fails to cause bulging, there is a certain probability of explosion, which is relatively dangerous. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a technical solution: comprising a box assembly 1, an energy absorption explosion-proof assembly 2 is arranged on one side of the box assembly 1, and an energy storage battery group 3 is arranged in the box assembly 1 and on one side of the energy absorption explosion-proof assembly 2;

[0022] The box assembly 1 comprises a box shell 101, an inner cavity 102 is formed in the box shell 101, a buzzer 103 is fixedly installed in the middle of the front of the inner cavity 102, a through hole 104 is formed on both sides of the front of the box shell 101, a box cover 105 is provided on the box shell 101, and an explosion-proof enclosure 106 is fixedly installed on the bottom surface of the inner cavity 102;

[0023] The energy-absorbing explosion-proof component 2 includes a support plate 201, a support head 202 is fixedly installed in the middle of the front of the support plate 201, an insertion shaft 203 is fixedly installed on both sides of the front of the support plate 201, a blocking ring 204 is fixedly installed at one end of the two insertion shafts 203 away from the support plate 201, and an energy-absorbing spring 205 is sleeved on each of the insertion shafts 203.

[0024] In this embodiment, the two plug shafts 203 correspond to the two through holes 104 one by one, and the plug shafts 203 are movably inserted in the through holes 104, and the two ends of the energy absorption spring 205 are respectively fixedly connected to the front of the abutment plate 201 and the inner wall of the inner cavity 102, and one end of the abutment head 202 is facing the switch button end of the buzzer 103. The front of the energy storage battery pack 3 is in contact with the back of the bottom abutment plate 201, and the energy storage battery pack 3 is fixedly placed in the explosion-proof enclosure 106. The back and both sides of the energy storage battery pack 3 are in contact with the inner wall of the explosion-proof enclosure 106. Once an explosion occurs, the abutment plate 201 moves outward and compresses the energy absorption spring 205. The energy absorption explosion-proof component 2 can provide a certain buffer position and absorb part of the energy of the explosion. Further, the box shell 101 and the explosion-proof enclosure 106 can play a multi-layer protection role.

[0025] A gap is provided between the explosion-proof enclosure 106 and the inner wall of the inner cavity 102, and a plurality of heat-conducting columns 107 are fixedly embedded on both side surfaces of the back of the explosion-proof enclosure 106, and the heat-conducting columns 107 are made of CU material. The other ends of the heat-conducting columns 107 extend to the outer wall of the box shell 101. The heat generated by the energy storage battery pack 3 during operation can be conducted to the outside of the box shell 101 through the plurality of heat-conducting columns 107, thereby dissipating heat without affecting the sealing of the battery box.

[0026] During use, the heat generated by the energy storage battery pack 3 during operation can be conducted to the outside of the box shell 101 through a plurality of heat-conducting columns 107, so that the heat can be dissipated without affecting the sealing of the battery box. At the same time, after long-term use, the energy storage battery pack 3 is deformed or bulged. At this time, since the two sides and the back of the energy storage battery pack 3 are restricted by the explosion-proof enclosure 106, the energy storage battery pack 3 can only bulge in the front direction once it is deformed. Once the energy storage battery pack 3 is deformed, it will squeeze the abutment plate 201. After being subjected to force, the abutment plate 201 will move to one side. The movement of the abutment plate 201 will drive the plug shaft 203 to move. Once the plug shaft 203 protrudes outward, the user can know that the energy storage battery pack 3 in the battery box is old and deformed, and the user can know the length of the protrusion. The deformation of the energy storage battery pack 3 can be easily known, thereby reminding the user that the battery box is at risk of explosion, thereby preventing the explosion. At the same time, once the energy storage battery pack 3 has an acute fault, the energy storage battery pack 3 is severely deformed and swells. At this time, the plate 201 will move outward and drive the head 202 to move and press the switch button of the buzzer 103. At this time, the buzzer 103 will immediately sound an alarm, thereby warning the user that the battery box has a serious fault and needs to be immediately away or isolated. Once an explosion occurs, the plate 201 moves outward and compresses the energy absorption spring 205. The energy absorption and explosion-proof component 2 can provide a certain buffer position and can also absorb part of the energy of the explosion. Further, the box shell 101 and the explosion-proof enclosure 106 can play a multi-layer protection role.

[0027] In summary, the explosion-proof energy storage battery box can conduct the heat generated by the energy storage battery pack 3 during operation to the outside of the box shell 101 through a plurality of heat-conducting columns 107, so that the heat can be dissipated without affecting the sealing of the battery box. At the same time, once the energy storage battery pack ages and deforms, it will squeeze the abutment plate 201. After being subjected to force, the abutment plate 201 will move to one side. The deformation of the energy storage battery pack 3 can be easily known by probing the length, thereby reminding the user that the battery box has the risk of explosion, thereby preventing the explosion. At the same time, once the energy storage battery pack 3 has an acute failure, the energy storage battery pack 3 swells up. At this time, the abutment plate 201 will move outward and drive the abutment head 202 to move and press the switch button of the buzzer 103. At this time, the buzzer 103 will immediately sound an alarm, thereby warning the user that the battery box has a serious failure and needs to be immediately moved away or isolated, which is safer.
