[0021] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0022] Reference below Figure 1-Figure 5 The present invention describes a vibration-damping base of an energy storage box according to an embodiment of the present invention, and further provides an energy storage box system.

[0023] like Figure 1 and Figure 2 As shown, the vibration-damping base of the energy storage box of the embodiment of the present invention comprises: a lower base 1 and an upper base 3, wherein the upper base 3 is arranged on the lower base 1, and the upper base 3 is used to place the energy storage box. The upper base 3 is welded by channel steel, and the lower base 1 is also welded by channel steel. An interface plate 5 is reserved on the lower base 1, and is used to connect the energy storage box transport vibration-damping base with the transport frame by using an adapter plate during transportation.

[0024] In addition, the vibration-damping base further includes: a vibration-damping assembly, which is arranged between the lower base 1 and the upper base 3 and / or on the upper base 3. That is, the vibration-damping assembly is arranged on the vibration-damping base, and the vibration of the energy storage box during transportation can be effectively absorbed by the vibration-damping assembly. Specifically, the vibration-damping assembly mainly realizes impact absorption in the vertical direction.

[0025] In addition, the vibration-damping base also includes: a locking assembly 4, which is arranged on the upper base 3, and has a locking position and an unlocking position. When the energy storage box is placed on the upper base 3, the locking assembly 4 is located in the locking position, and the locking assembly 4 and the energy storage box are locked in cooperation.

[0026] That is, by providing the locking assembly 4, the energy storage box can be locked on the upper base 3, thereby preventing the energy storage box from moving during transportation.

[0027] Therefore, by providing the vibration-damping assembly and the locking assembly 4, the energy storage box can not only be firmly fixed on the vibration-damping base during transportation, but also the vibration of the energy storage box during transportation can be effectively absorbed by the vibration-damping assembly on the vibration-damping base.

[0028] Of course, the vibration-damping base can also absorb the vibration of the energy storage box when it is working.

[0029] Among them, refer to Figure 5 As shown, the locking assembly 4 includes: a lock core 8 and a screw 9. The lock core 8 is arranged at one end of the screw 9, and the lock core 8 can rotate relative to the screw 9. A locking rod is arranged on the lock core 8, and the locking rod is suitable for locking with the energy storage box. In other words, the screw 9 is arranged below the lock core 8, and the lock core 8 can rotate relative to the screw 9. The lock core 8 can reciprocate between the locked position and the unlocked position, thereby driving the locking rod on the lock core 8 to rotate between the locked position and the unlocked position, thereby realizing the locking and unlocking of the energy storage box.

[0030] Furthermore, a bearing is provided between the lock core 8 and the screw rod 9 to facilitate the rotation of the lock core 8 relative to the screw rod 9 .

[0031] The locking assembly 4 further includes a driving member, which is in transmission connection with the lock core 8, and is used to drive the lock core 8 to rotate between the locked position and the unlocked position. In other words, the driving member can drive the lock core 8 to rotate in the circumferential direction, so that the lock core 8 can rotate between the locked position and the unlocked position.

[0032] Among them, the driving member can be a driving motor, and a pressure sensor or an optical sensor is arranged on the upper base 3. When the energy storage box is placed on the upper base 3, the pressure sensor or the optical sensor is triggered, the driving motor starts and drives the lock core 8 to rotate in the circumferential direction, so that the lock core 8 rotates from the unlocking position to the locking position, thereby realizing the locking cooperation between the lock core 8 and the energy storage box.

[0033] Of course, the driving member can also be composed of a transmission rod and an elastic member, one end of the transmission rod is arranged on the upper base 3 and the other end is in contact with the elastic member. When the energy storage box is placed on the upper base 3, one end of the transmission rod is triggered, so that the other end of the transmission rod releases the elastic member, and the elastic member drives the lock core 8 to rotate in the circumferential direction, so that the lock core 8 rotates from the unlocking position to the locking position, thereby realizing the locking cooperation between the lock core 8 and the energy storage box.

[0034] Further, refer to Figure 5As shown, the locking assembly 4 also includes: an adjusting member 10, the adjusting member 10 and the screw rod 9 are in transmission cooperation, and the adjusting member 10 is suitable for adjusting the height of the screw rod 9. In other words, by providing the adjusting member 10, the lock core 8 can be moved in the up and down directions, so that energy storage boxes of different specifications and sizes can be locked.

[0035] Among them, the adjustment member 10 can be a nut. When the nut is turned, the screw 9 can move in the up and down directions, so that the position of the lock core 8 in the up and down directions can be adjusted, and then the energy storage boxes of different specifications and sizes can be locked.

[0036] Among them, refer to Figure 3 As shown, the vibration-damping base further includes: a plurality of positioning plates 6, which are arranged at intervals at the edge of the upper base 3, and the plurality of positioning plates 6 define a matching space suitable for matching with the energy storage box, and a guiding inclined surface is arranged on the inner side of the positioning plates 6. In other words, a plurality of positioning plates 6 are arranged at intervals at the edge of the upper base 3, and the plurality of positioning plates 6 can define a matching space, that is, the energy storage box is matched in the matching space.

[0037] Further, refer to Figure 3 As shown, a guiding slope is provided on one side of the positioning plate 6 facing the matching space, and the guiding slope can play a guiding role, so that the energy storage box can be more smoothly matched in the matching space.

[0038] Furthermore, a plurality of positioning plates 6 may be arranged at intervals in the length direction and the width direction of the upper base 3 .

[0039] In addition, refer to Figure 3 As shown, the vibration-damping base also includes: a plurality of limit members 7, and the plurality of limit members 7 are respectively arranged on a plurality of positioning plates 6, and the position of the limit members 7 on the positioning plates 6 is adjustable to be suitable for adjusting the size of the matching space. In other words, the limit members 7 are arranged on the positioning plates 6, wherein the position between the limit members 7 and the positioning plates 6 is adjustable, that is, the size of the limit members 7 extending relative to the positioning plates 6 is different. Since the external dimensions of the energy storage box may be different due to errors during production, by providing an adjustable limit member 7, the limit member 7 can adjust the size of the matching space, and then the plurality of positioning plates 6 can limit energy storage boxes of different sizes.

[0040] Furthermore, the limiting member 7 may be a bolt, and the size of the fitting space may be adjusted by adjusting the length of the bolt extending relative to the positioning plate 6 .

[0041] Furthermore, the bolts can abut against the outer wall of the energy storage box, thereby fixing the energy storage box.

[0042] like Figure 1As shown, the vibration reduction assembly includes: a plurality of first vibration reduction members 2, and the plurality of first vibration reduction members 2 are arranged at intervals between the upper base 3 and the lower base 1. The first vibration reduction members 2 are arranged between the upper base 3 and the lower base 1, and the first vibration reduction members 2 can effectively absorb the vibration between the upper base 3 and the lower base 1, thereby preventing the vibration energy on the lower base 1 from being transmitted to the upper base 3, thereby achieving vibration reduction of the energy storage box; similarly, when the upper base 3 shakes, the shaking energy of the upper base 3 can be absorbed by the first vibration reduction members 2, thereby achieving vibration reduction of the energy storage box.

[0043] like Figure 4 As shown, the vibration reduction assembly further includes: a second vibration reduction member 11, which is arranged on the side of the upper base 3 away from the lower base 1. The second vibration reduction member 11 is in direct contact with the energy storage box, so the second vibration reduction member 11 can be used to reduce the impact during transportation.

[0044] Among them, the first vibration damper 2 can be a wire rope vibration damper. The wire rope vibration damper has a simple structure and is easy to install and maintain. In addition, the wire rope vibration damper has a long service life. Due to its structural design and material selection, the wire rope vibration damper has a long service life. In addition, the wire rope vibration damper has a good vibration reduction effect, that is, the wire rope vibration damper can effectively reduce the vibration and impact generated by mechanical equipment during operation, and protect the safety of equipment and workers.

[0045] Furthermore, the second vibration damping member 11 may be a rubber pad. The rubber pad is characterized by high elasticity and high viscosity. The elasticity of rubber is generated by the change of its curled molecular conformation. The interaction between rubber molecules will hinder the movement of the molecular chain, thereby showing the characteristics of viscous damping, so that stress and strain are often in an unbalanced state.

[0046] The wire rope vibration isolator in the vibration-isolating base plays a role in vibration reduction and impact resistance during transportation. However, the energy storage box is a heavy-duty equipment. During the selection process of the wire rope vibration isolator, its stiffness needs to be met, and its impact transmission efficiency is reduced. Simulation shows that the wire rope vibration isolator has the lowest transmission rate, especially in the vertical direction of the equipment. Therefore, a dual vibration reduction model of wire rope vibration isolator and rubber pad is adopted to further improve the vertical impact resistance of the equipment.

[0047] According to the second aspect of the present invention, the energy storage box system includes: an energy storage box and a vibration-damping base of the energy storage box, and the energy storage box is placed on the vibration-damping base of the energy storage box.
