Description

Technical Field

[0001] The present invention relates to the technical field of batteries, and particularly to a monolithic integrated solid-state sodium-ion battery. Background Art

[0002] The monolithic integrated solid-state sodium-ion battery is a new type of battery technology that integrates a solid electrolyte, a positive electrode material, and a negative electrode material in a single sheet-like structure. It is not a multi-layer stacked structure. This design can reduce the volume and weight of the battery, improve the energy density of the battery, and has high safety and a long cycle life. The most important point is that sodium resources are abundant, causing less damage to the environment, and the treatment process is relatively environmentally friendly.

[0003] Although the existing monolithic integrated solid-state sodium-ion batteries have many advantages in use, there are still certain deficiencies. That is, the monolithic integrated solid-state sodium-ion batteries generally form a battery pack in groups, and when the batteries are installed on a battery carrier, they need to be fixed one by one to complete the installation. The operation is relatively cumbersome and not convenient. Moreover, in order to meet the requirements in terms of volume and size, the structure of the battery carrier is generally set to be relatively compact. In this way, when a certain battery fails and needs to be replaced, it will be relatively troublesome to disassemble due to the limitation of the battery carrier structure. Furthermore, when it is not working and needs to be transferred or stored, there is also a lack of appropriate protection mechanisms, making the battery vulnerable to accidental damage.

[0040] On one side of the protective movable sleeve 5 near the connecting convex frame 51, a support guiding hole 52 is formed. A limiting bearing rod 271 is inserted into the support guiding hole 52. A plurality of limiting pressing plates 53 are fixedly arranged inside the protective movable sleeve 5, and the surfaces of the limiting pressing plates 53 are smooth and free of burrs. When the limiting pressing plates 53 play a role in limiting the battery body 1, they press on the battery body 1. On the side of the inside of the protective movable sleeve 5 far from the connecting convex frame 51, a plurality of pushing contact rods 54 are also fixedly arranged.

[0041] An L-shaped bearing plate 6 is also installed on the support loading plate 2. An installation matching through hole 61 is formed in the lower side of the L-shaped bearing plate 6. A matching support rod 28 is inserted into the installation matching through hole 61. A first support spring 611 is sleeved on the matching support rod 28, and both ends of the first support spring 611 are respectively fixed on the support limiting plate 281 and the L-shaped bearing plate 6.

A downward extension connecting plate 63 is fixedly arranged at the lower end of the double-slope convex block 62. A connecting matching hinge rod 64 is hinged at the lower end of the downward extension connecting plate 63. The upper end of the connecting matching hinge rod 64 is hinged with a movable assembly plate 7.

[0043] A matching guiding hole 71 is formed in the lower end of the movable assembly plate 7. A support guiding rod 291 is inserted into the matching guiding hole 71. A second support spring 711 is sleeved on the support guiding rod 291, and both ends of the second support spring 711 are respectively fixed on the bearing support block 29 and the lower end surface of the movable assembly plate 7.

[0044] A matching top plate 72 is fixedly arranged at the upper end of the movable assembly plate 7. A downward extension support plate 73 is fixedly arranged on the matching top plate 72. A matching bottom frame 74 is fixedly arranged at the lower end of the downward extension support plate 73. The matching bottom frame 74 is hinged with the upper end of the connecting matching hinge rod 64.

[0045] A bearing plate strip 75 is also fixedly arranged on one side of the movable assembly plate 7. A plurality of limiting plate strips 76 are fixedly arranged on the bearing plate strip 75. A matching channel 77 is formed in the limiting plate strip 76. An inserting locking plate 8 is inserted into the matching channel 77. When the limiting plate strip 76 plays a role in limiting the battery body 1, it is located at the notch on one side of the battery installation groove 22.

[0046] A connecting bar 81 is fixedly arranged on the plug-in locking plate 8. One end of the connecting bar 81 far away from the plug-in locking plate 8 is fixedly provided with a supporting carrier plate 82. An inclined surface convex block 83 is fixedly arranged on the supporting carrier plate 82. Limit contact plates 831 are symmetrically and fixedly arranged at the upper and lower ends of the inclined surface convex block 83. Moreover, an elastic connecting piece 84 is also fixedly arranged on the supporting carrier plate 82. The other end of the elastic connecting piece 84 is fixed on the limit plate strip 76. In addition, when the plug-in locking plate 8 fixes the battery body 1, it is plugged into the locking plug-in slot 11. When the push-contact rod 54 is plugged between the limit contact plates 831, it contacts the upper and lower limit contact plates 831.

[0047] When the device is not in use, the protective movable sleeve 5 is sleeved on the support battery panel 21, so that the battery body 1 is inside the protective movable sleeve 5. The protective movable sleeve 5 can play a good protective role for the battery body 1, ensuring the safety of the battery body 1 during transportation and storage. At this time, the limit pressure plate 53 in the protective movable sleeve 5 presses on the battery body 1, and the limit plate strip 76 blocks the side notch of the battery installation groove 22, fully ensuring the stability of the battery body 1. When the battery body 1 is working, the rotating threaded assembly rod 3 drives the driving assembly plate 4 to move downward under the action of the thread. As the driving assembly plate 4 moves downward, under the action of the movable connecting hinge rod 44, it will push the protective movable sleeve 5 to move away from the support load-bearing plate 2. And during the downward movement of the driving assembly plate 4, the pushing cylinder block 43 on the limit support rod 42 will contact the inclined surface at the upper end of the double-inclined surface convex block 62. In this way, under the cooperation of the pushing cylinder block 43 and the inclined surface, it will push the L-shaped bearing plate 6 to move towards the support load-bearing plate 2 until the pushing cylinder block 43 moves onto the flat surface of the double-inclined surface convex block 62. As the L-shaped bearing plate 6 moves, under the action of the connecting and cooperating hinge rod 64, it will drive the movable assembly plate 7 to move downward, which will also drive the limit plate strip 76 to move downward, so that it no longer blocks the notch of the battery installation groove 22. In this state, the battery body 1 is in a fully unlocked state, and at this time the protective movable sleeve 5 is no longer sleeved on the support battery panel 21, and the battery body 1 can be quickly disassembled and replaced. As the driving assembly plate 4 continues to move downward, the pushing cylinder block 43 will cross over the double-inclined surface convex block 62. In this way, under the action of the first support spring 611, it will drive the L-shaped bearing plate 6 to reset, and at the same time will also cause the movable assembly plate 7 to reset, and the limit plate strip 76 will again block the notch of the battery installation groove 22. Then, as the driving assembly plate 4 further moves downward, it will also drive the pushing contact rod 54 on the protective movable sleeve 5 to contact the inclined surface convex block 83 on the support load-bearing plate 82. In this way, under the cooperation of the pushing contact rod 54 and the inclined surface convex block 83, it will drive the plug-in locking plate 8 to move, and then the plug-in locking plate 8 is inserted into the locking plug-in groove 11 on the battery body 1. At this time, the battery body 1 is in a fully fixed state, which can fully ensure its stability and firmness during the working process. And at this time, the pushing contact rod 54 is between the two limit contact plates 831. Under the action of the pushing contact rod 54, it can play a good fixing role for the movable assembly plate 7, and further fix the limit plate strip 76, so that it can stably be at the notch of the battery installation groove 22. In addition, a ventilation through hole 23 is opened at the bottom of the battery installation groove 22, which is communicated with the ventilation cavity 24, facilitating the heat dissipation of the battery body 1 during the working process. When a certain battery body 1 fails and needs to be replaced, the threaded assembly rod 3 can be rotated in the reverse direction to drive the driving assembly plate 4 to move upward, so that the pushing cylinder block 43 abuts on the flat surface of the double-inclined surface convex block 62. In this way, it can drive the movable assembly plate 7 to move downward again,The limiting strip 76 is no longer blocked at the notch of the battery installation groove 22, facilitating the removal and placement of the battery body 1. The operation is simple, convenient and fast, without the need to operate each battery body 1 one by one, greatly improving the installation and removal efficiency of the battery body 1, reducing the workload of the staff, and being very practical.
