To be added, in order to elastically connect the sliding damper 200 to each outer side surface of the square housing 100 and enable the sliding damper 200 to be positioned in the middle of the square housing 100 when not being stressed, specifically, the upper and lower ends of the sliding damper 200 are provided with springs, so that one end of the springs away from the sliding damper 200 is connected to the square housing 100.
It should be further noted that, to prevent the solid-state battery 500 from being directly contacted with the coolant and being shorted, a battery protection sleeve is further wrapped around the outer peripheral wall of the solid-state battery 500, and the battery protection sleeve is made of an insulating material with good thermal conductivity and corrosion resistance.
The cross-sectional shape of the coolant flow channels 110 is elliptical, so that cracks in the coolant flow channels 110 due to local stress concentration are avoided when the coolant flows between the coolant flow channels 110.
When the square shell type camera is used, a worker can connect a plurality of square shells 100 according to a photographic fit path according to the specific shape of the installation space, if the installation space is long, the square shells 100 are connected into a row, if the installation space is wide, the square shells 100 are arranged and connected in a matrix form, and if the installation space is square, the square shells 100 are connected into a matched square;
the connection between the adjacent square housings 100 is illustrated by taking two square housings 100 as an example, a worker firstly places one square housing 100 in the installation area, then places the other square housing 100 from top to bottom to a position adjacent to the previously placed square housing 100, and makes the lower end face of the sliding baffle 200 corresponding to one side of the subsequently placed square housing 100 abut against the upper end face of the sliding baffle 200 corresponding to one side of the previously placed square housing 100, under the action of the elastic force of the spring, the sliding baffle 200 corresponding to the subsequently placed square housing 100 moves from the middle position to the upper limit position, the sliding baffle 200 corresponding to the previously placed square housing 100 moves from the middle position to the lower limit position, at this time, as shown in fig. 15 and 16, the sliding baffle 200 does not seal the cooling liquid flow channel 110 alone, but surrounds the cooling liquid flow channel 110, a first-stage seal is formed, the cooling liquid is prevented from overflowing to the outside of the square housing 100 at this time, the cooling liquid can flow into the other square housing 100 through the cooling liquid flow channel 110, the cooling liquid can flow into the other square housing 100, and then the two square housings can be circulated by connecting one square housing 100 to the two liquid circulation pumps, and the liquid can flow out from the other square housing 100.
When the plurality of square housings 100 are arranged in a matrix, the coolant flow channels 110 between two adjacent square housings 100 are all connected, and the coolant has a plurality of flow paths when flowing between the plurality of square housings 100, so that the temperature uniformity is better, the temperature difference of the coolant is smaller, and the difference in cooling effect of the coolant on the solid-state batteries 500 in the respective square housings 100 is not large, compared to a single flow path, when the coolant circulates between the respective square housings 100, and thus the difference in the service lives of the solid-state batteries 500 in the respective square housings 100 can be reduced.
In a further embodiment, as shown in fig. 5, 11 and 16, the solid-state energy storage battery pack further includes a bi-directional ratchet plate 300, the bi-directional ratchet plate 300 extending vertically, the bi-directional ratchet plate 300 being elastically connected to the sliding shutter 200, the bi-directional ratchet plate 300 being also elastically connected to the square housing 100, the bi-directional ratchet plate 300 being movable in a vertical direction; when the sliding shutter 200 moves from the intermediate position to the upper limit position or the lower limit position, the ratchet teeth on the opposite two-way ratchet plates 300 partially overlap in the vertical direction; the solid state energy storage battery pack further comprises magnetic strips 400, the magnetic strips 400 are mounted at four corners of the square housing 100, and the magnetic strips 400 are used for enabling the ratchet overlapping portions of the bidirectional ratchet plates 300 to mutually tooth.
To be added, in order to realize the elastic connection between the bidirectional ratchet plate 300 and the sliding baffle 200, specifically, the middle part of the bidirectional ratchet plate 300 is connected with a first upper compression spring 911 extending upwards, the middle part of the bidirectional ratchet plate 300 is connected with a first lower compression spring 912 extending downwards, in order to realize the elastic connection between the bidirectional ratchet plate 300 and the square shell 100, the middle part of the bidirectional ratchet plate 300 is also connected with a second upper compression spring 921 extending upwards, and the middle part of the bidirectional ratchet plate 300 is also connected with a second lower compression spring 922 extending downwards.
It is further added that, in order to make the magnetic strip 400 magnetically attract the ratchet surface towards the bidirectional ratchet plate 300, the ratchet surface of the bidirectional ratchet plate 300 may be made of cast iron material or magnetic material, and when the magnetic material is selected, the magnetism of the magnetic material is opposite to that of the ratchet surface of the magnetic strip 400 facing the bidirectional ratchet plate 300, so that the magnetic strip 400 can generate magnetic attraction force on the ratchet surface towards the bidirectional ratchet plate 300.
Taking the connection of two square shells 100 as an example, when the sliding baffle 200 on one side of the two square shells 100 connected to each other moves from the middle position to the upper limit position and the lower limit position respectively, the bidirectional ratchet plate 300 connected to the sliding baffle 200 moving to the upper limit position moves downward relative to the sliding baffle 200, and the bidirectional ratchet plate 300 connected to the sliding baffle 200 moving to the lower limit position moves upward relative to the sliding baffle 200, so that the ratchets of the two bidirectional ratchet plates 300 are partially overlapped in the vertical direction, and the two bidirectional ratchet plates 300 are close to each other under the magnetic attraction force of the magnetic stripe 400, so that the overlapped parts of the ratchets of the two bidirectional ratchet plates 300 are meshed together, and the two square shells 100 are connected together; in summary, in the process of connecting the two square housings 100, not only special installation tools (such as a wrench and a caliper) are not needed, but also the space utilization rate is higher, the square housings 100 can be vertically placed to complete the installation, and no extra space is needed for installing the square housings 100.
In a further embodiment, as shown in fig. 11 and 16, magnetic strips 400 are removably mounted to the four corners of the square housing 100.
When two square shells 100 connected together need to be disassembled, a worker only needs to take out the magnetic strip 400 from the square shells 100, at the moment, after the magnetic attraction force is lost, the two mutually toothed two bidirectional ratchet plates 300 are not toothed together, at the moment, under the driving of the spring force between the bidirectional ratchet plates 300 and the sliding baffle 200 and the spring force between the square shells 100 and the bidirectional ratchet plates 300, the two square shells 100 are staggered up and down, at the moment, the worker can take down the square shells 100 staggered upwards firstly, and take down the other square shells 100.
It should be further added that, for installing the magnetic stripe 400, triangular grooves 130 are formed at four corners of the square housing 100, the external dimensions of the triangular grooves 130 are adapted to those of the magnetic stripe 400, so that the magnetic stripe 400 can be fixed in the triangular grooves 130, and the triangular grooves 130 and the magnetic stripe 400 are in interference fit, so that the magnetic stripe 400 is fixed in the triangular grooves 130 by friction force.
In a further embodiment, as shown in fig. 16, a first elastic member 600 is provided between the bi-directional ratchet plate 300 and the square housing 100, and the first elastic member 600 is used to elastically reset the bi-directional ratchet plate 300 when the magnetic stripe 400 is detached from the square housing 100.
It should be noted that, since the first upper compression spring 911, the first lower compression spring 912, the second upper compression spring 921 and the second lower compression spring 922 are compression springs, the deformability thereof in the radial direction is poor, the elastic restoring effect on the bi-directional ratchet plate 300 is poor, so that the elastic restoring effect on the bi-directional ratchet plate 300 is better, the first elastic assembly 600 is provided between the bi-directional ratchet plate 300 and the square housing 100, and the first elastic assembly 600 is used for elastically restoring the bi-directional ratchet plate 300 after the magnetic stripe 400 is taken out.
