Description

Technical Field

[0001] This utility model provides a collision avoidance aid for new energy marine battery packs, belonging to the field of battery pack protection technology. Background Technology

[0002] New energy ships refer to vessels that use non-traditional fossil fuels as their power source, aiming to reduce environmental pollution and improve energy efficiency. Among them, electric ships rely entirely on battery energy storage systems for power and are suitable for coastal and inland waters. Based on the power source, electric ships can be further divided into: pure battery-powered ships (all power comes from batteries, suitable for short-distance voyages and waters with high environmental protection requirements) and hybrid ships (combining batteries and traditional fuel engines, which can flexibly switch power modes under different operating conditions and are suitable for long-distance voyages).

[0003] Existing battery packs for new energy ships can generally meet normal usage needs, and are usually equipped with external protective shells for protection. However, when a foreign object collides with the battery pack during the ship's operation, the protective shell is directly impacted, making it very easy for it to dent and damage the internal battery pack. Therefore, the collision protection effect needs improvement. Based on this, this invention provides a collision protection aid for battery packs for new energy ships. Utility Model Content

[0004] The technical problem solved by this utility model is that the protective shell is easily crushed by direct external impact, which can damage the internal battery pack, and the anti-collision effect needs to be improved.

[0005] To solve the technical problem, the technical solution provided by this utility model is as follows: a collision avoidance auxiliary device for a new energy marine battery pack, including a base plate, a battery pack on the top of the base plate, a protective shell placed outside the battery pack, a collision avoidance component on the outside of the protective shell, the collision avoidance component including a buffer cover, buffer rubber cylinders and buffer springs symmetrically provided on both sides of the inner side wall and the inner top wall of the buffer cover, which are fixedly connected to the side wall of the protective shell, and the buffer springs are placed inside the buffer rubber cylinders. Several collision avoidance airbags are provided on the side wall and the top wall of the protective shell, which are placed between the buffer rubber cylinders.

[0006] Furthermore, the bottom plate has several mounting holes at its edge, and the protective shell has several bolts at its edge that are fixedly connected to the top of the bottom plate.

[0007] Furthermore, the protective shell sidewall is provided with several heat dissipation grilles, and the buffer cover sidewall is provided with several heat dissipation holes placed on one side of the heat dissipation grilles.

[0008] Furthermore, the outer wall of the protective shell is provided with a blower fan placed inside the heat dissipation grille.

[0009] Furthermore, the bottom of the buffer cover is open, and the cross-sectional dimension of the buffer cover is larger than the cross-sectional dimension of the base plate.

[0010] Furthermore, the height of the anti-collision airbag is less than 1 / 3 of the height of the buffer rubber cylinder.

[0011] The beneficial effects of this utility model are:

[0012] By installing anti-collision components on the outside of the protective shell, external objects will first hit the buffer cover, causing it to move towards the protective shell. This will cause the buffer spring and buffer rubber cylinder to deform under force. The buffer rubber cylinder can suppress the simple harmonic vibration of the buffer spring, thereby generating damping force. When the buffer cover is compressed to a certain extent, the anti-collision airbag, together with the buffer spring and buffer rubber cylinder, further blocks the buffer cover that is moving towards the protective shell, enhancing the buffering capacity and effectively preventing the protective shell from being directly impacted by external forces and being crushed, thus preventing damage to the internal battery pack. The anti-collision effect is greatly improved. Attached Figure Description

Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.

[0019] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0020] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] According to the appendix Figure 2 , 3 As shown: This utility model provides a collision avoidance aid for a new energy marine battery pack: including a base plate 1, a battery pack on the top of the base plate 1, a protective shell 2 placed outside the battery pack, a number of heat dissipation grilles 9 on the side wall of the protective shell 2, and a number of mounting holes at the edge of the base plate 1 for installing the base plate 1 in the battery compartment of the new energy ship. A number of bolts 8 are fixedly connected to the top of the base plate 1 at the edge of the protective shell 2 for fixing the installation. Specifically, a protective space is formed between the top of the base plate 1 and the inside of the protective shell 2, located outside the battery pack. The heat generated by the battery pack during operation is dissipated outward from the protective space through the heat dissipation grilles 9.

[0022] As per the instruction manual Figure 1 , 3 As shown in Figure 4: The protective shell 2 is provided with an anti-collision component 4 on its outer side. The anti-collision component 4 includes a buffer cover 3. The inner sidewalls and the inner top wall of the buffer cover 3 are symmetrically provided with buffer rubber cylinders 5 and buffer springs 6, which are fixedly connected to the sidewalls of the protective shell 2. The buffer springs 6 are placed inside the buffer rubber cylinders 5. After the collision, the buffer springs 6 and the buffer rubber cylinders 5 rebound. The buffer rubber cylinders 5 are made of rubber and can generate a large deformation under a small external force. After the external force is removed, they can return to their original shape, thus suppressing the repeated rebound of the buffer springs 6. The protective shell 2 has several anti-collision components placed between the buffer rubber cylinders 5 on its sidewalls and the top wall. The height of the airbag 7 is less than 1 / 3 of the height of the buffer rubber cylinder 5, so as not to affect the normal compression of the buffer rubber cylinder 5. Specifically, when an external object hits the battery pack, the external object will first hit the buffer cover 3 and move it towards the protective shell 2, which will cause the buffer spring 6 and the buffer rubber cylinder 5 to be deformed by force. The buffer rubber cylinder 5 can suppress the simple harmonic vibration of the buffer spring 6, thereby generating damping force, reducing vibration and dissipating energy. When the buffer cover 3 is compressed to the remaining 1 / 3 of its height, the airbag 7, together with the buffer spring 6 and the buffer rubber cylinder 5, further blocks the buffer cover 3 that is moving towards the protective shell 2.

[0023] As per the instruction manual Figure 2 , 4As shown: The bottom of the buffer cover 3 is open, and the cross-sectional dimension of the buffer cover 3 is larger than that of the bottom plate 1. Heat can also be diffused from the bottom of the buffer cover 3 to the outside. The side wall of the buffer cover 3 is provided with several heat dissipation holes 10 placed on one side of the heat dissipation grille 9. The outer wall of the protective shell 2 is provided with a blower 11 placed inside the heat dissipation grille 9. Specifically, the heat generated by the operation of the battery pack is dissipated from the protective space to the buffer cover 3 through the heat dissipation grille 9. When the blower 11 is activated, the heat located inside the buffer cover 3 is discharged to the outside through the heat dissipation holes 10, effectively preventing heat accumulation from affecting the operation of the battery pack.

[0024] The principle of this utility model

[0025] In use, when a foreign object impacts the battery pack while the new energy ship is in motion, the object will first hit the buffer cover 3, causing it to move towards the protective shell 2. This will cause the buffer spring 6 and the buffer rubber cylinder 5 to deform under force. The buffer spring 6 and the buffer rubber cylinder 5 closer to the impact direction will compress and deform, while the buffer spring 6 and the buffer rubber cylinder 5 farther away from the impact direction will stretch and deform. The buffer rubber cylinder 5 can suppress the simple harmonic vibration of the buffer spring 6, thereby generating damping force, reducing vibration and dissipating energy. When the buffer cover 3 is compressed to the remaining 1 / 3 height, the anti-collision airbag 7, together with the buffer spring 6 and the buffer rubber cylinder 5, will further block the buffer cover 3 that is moving towards the protective shell 2, enhance the buffering capacity, and effectively prevent the protective shell 2 from being directly impacted by external force and being crushed, which would damage the internal battery pack. The anti-collision effect is greatly improved.

This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
