Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Embodiment 1: This embodiment provides a new energy ship battery anti-vibration fastening device, see Figure 1-Figure 9 Specifically, it includes an open box 1, and a number of evenly distributed elliptical through holes are opened on the four sides of the open box 1, the front, back, left and right sides, and the elliptical through holes can reduce the overall weight of the device, and at the same time play a role in buffering vibration to a certain extent, and can also facilitate air circulation and heat dissipation. The open design is convenient for the installation and maintenance of internal parts; a suspended shock-absorbing plate 2 is provided in the middle and lower part of the open box 1, and the shock-absorbing plate 2 provides a supporting plane below for the battery 40, and by connecting with the piston shock-absorbing assembly, it can effectively buffer the vibration from below and protect the battery 40 from vibration impact. The shock-absorbing plate 2 is connected to the open box 1 through the piston shock-absorbing assembly; In order to ensure the stability of the placement of the battery 40, four circularly distributed trapezoidal legs 3 are fixedly arranged on the top surface of the open box 1, and the trapezoidal legs 3 support the loading plate 4 and the battery 40, and transfer the weight of the battery 40 to the open box 1. At the same time, its trapezoidal structure can increase stability, and the top surfaces of the four trapezoidal legs 3 are fixedly provided with the loading plate 4, and the loading plate 4 provides a placement platform for the battery 40; A battery 40 is placed on the top surface of the loading plate 4. Trapezoidal side plates 12 are suspended in the front, back, left, and right directions of the loading plate 4. After the battery 40 is placed, the trapezoidal side plates 12 can be translated toward the battery 40. The elastic balls 16 are against the sides of the battery 40 to achieve preliminary clamping and fixing of the battery 40. At the same time, the elastic balls 16 can adapt to the uneven surface of the battery 40 to reduce damage to the surface of the battery 40. Each trapezoidal side plate 12 is connected to the trapezoidal leg 3 on the same side through a hinge assembly. A plurality of evenly distributed elastic balls 16 are hingedly provided on the inner side surface of each trapezoidal side plate 12, and each elastic ball 16 abuts against the corresponding side surface of the battery 40. When clamping the battery 40, the elastic ball 16 can not only provide a certain pressure to fix the battery 40, but also reduce the wear on the surface of the battery 40 through its own rolling and elasticity, thereby protecting the battery 40. The outer side surfaces of a pair of trapezoidal side panels 12 on the left and right sides are both provided with trapezoidal slots 21, which provide installation and movement space for components such as the rotating slide bar 27, so as to further tighten the top surface of the battery 40. A pair of first sliding holes are provided on the inner bottom wall of each trapezoidal slot 21, and a rotating slide bar 27 is slidably inserted inside each first sliding hole. The rotating slide bar 27 drives the rotating swing arm 30 and the elastic pressing block 31 to move by sliding in the first sliding hole and rotating itself, so as to tighten the top surface of the battery 40. A rotating swing arm 30 is fixedly provided at the top end of each rotating slide bar 27. The rotating swing arm 30 transmits the movement of the rotating slide bar 27, driving the elastic pressure block 31 to contact the top surface of the battery 40, thereby re-clamping and fixing the battery 40. An elastic pressure block 31 is fixedly provided at the outer end of each rotating swing arm 30. The elastic pressure block 31 abuts against the top surface of the battery 40 to provide upward pressure, further fixing the battery 40 and preventing the battery 40 from shaking in the device. The elastic material can avoid damage to the top surface of the battery 40. Each elastic pressure block 31 abuts against the top surface of the battery 40, and each rotating slide bar 27 is connected to the trapezoidal slot 21 on the same side through a limiting mechanism.

[0019] In the specific implementation process, Figure 4 and Figure 5 As shown, fixed inclined plates 5 are fixed at the middle and lower parts of the four corners in the open box 1.

The outer end of each fixed inclined plate 5 is provided with a second sliding hole. The four corners of the bottom surface of the shock absorbing plate 2 are fixed with fixed sliding rods 6. The fixed sliding rods 6 slide in the second sliding holes of the fixed inclined plates 5 and work together with the fixed springs 42 to buffer vibrations and ensure the stability of the shock absorbing plate 2 and the battery 40. The bottom end of each fixed sliding rod 6 is slidably inserted in the second sliding hole on the corresponding side, and the upper half of each fixed sliding rod 6 is sleeved with a fixed spring 42.

The piston damping assembly includes a piston slide rod 8 and a piston slide cylinder 11. The four corners of the top surface of the damping plate 2 are fixedly provided with first U-shaped ear seats 7. A first single ear seat is hingedly provided in the opening of each first U-shaped ear seat 7. The outer end of each first single ear seat is fixedly provided with a piston slide rod 8.

A second U-shaped ear seat 10 is fixedly provided at the middle and lower parts of the four corners in the open box 1, and a second single ear seat is hingedly provided in the opening of each second U-shaped ear seat 10, and a piston slide 11 is fixedly provided at the outer end of each second single ear seat, and a piston slider 9 is slidably provided inside each piston slide 11, and the second U-shaped ear seat 10 at the middle and lower parts of the four corners in the open box 1 is connected to the piston slide 11 through the second single ear seat; The outer end of each piston slide rod 8 is slidably inserted into the outer port of the piston slide cylinder 11 on the corresponding side, and the outer end of each piston slide rod 8 is fixedly connected to the corresponding piston slider 9. The outer section of each piston slide rod 8 is sleeved with a piston spring 41, and the two ends of each piston spring 41 are respectively against the piston slide cylinder 11 and the piston slider 9. When the device is vibrated, the piston slide rod 8 and the piston slider 9 slide in the piston slide cylinder 11, and the piston spring 41 undergoes elastic deformation. The vibration energy is absorbed and buffered by the expansion and contraction of the piston spring 41, thereby reducing the vibration transmitted to the battery 40 and improving the shockproof effect of the battery 40.

[0021] Embodiment 3: Based on Embodiment 2, this embodiment further includes: In the specific implementation process, Figure 8 and Fig. 9 As shown, two pairs of first rails 17 are fixedly arranged on both sides of the trapezoidal slot 21. The first rails 17 cooperate with the hollow slider 22 to provide a sliding track for the hollow slider 22, thereby ensuring the stability and accuracy of the movement of the hollow slider 22. A vertically distributed hollow slider 22 is slidably engaged between each pair of first rails 17. The hollow slider 22 drives the rotating slide rod 27 to move by sliding on the first rails 17. A fourth sliding hole is provided in the middle of the hollow slider 22, and the middle of the rotating slider 27 is rotated and inserted into the fourth sliding hole. A pair of limit stop rings 28 are fixed in the middle of the rotating slider 27, and the pair of limit stop rings 28 are distributed on the upper and lower sides of the hollow slider 22. The limit stop rings 28 can prevent the rotating slider 27 from detaching from the hollow slider 22, and at the same time allow the rotating slider 27 to rotate in the hollow slider 22; The limiting mechanism includes a limiting sleeve 29 and a second T-shaped pin 20. The upper and middle part of the rotating slide bar 27 is sleeved with a concentrically fixed limiting sleeve 29. The outer surface of the limiting sleeve 29 is provided with a bending groove 32. The upper half of the bending groove 32 is a vertical groove and the lower half is an arc-shaped distribution. A pair of second T-shaped pins 20 are fixed at the two corners of the top inside the trapezoidal groove 21. The outer end of the second T-shaped pin 20 is slidably engaged in the bending groove 32 on the corresponding side. During the movement of the rotating slide bar 27, the movement trajectory of the rotating slide bar 27 is limited by the cooperation between the bending groove 32 and the second T-shaped pin 20, so that it slides downward first and then rotates, thereby accurately realizing the tightening operation of the battery 40.

[0022] It should be noted that: in this embodiment, a pair of driven shafts 23 are rotatably inserted in the middle of the trapezoidal slot 21, and the driven shaft 23 supports the driven gear 24 and transmits the rotation of the driven gear 24, driving the driven swing arm 25 to move. The middle of each driven shaft 23 is rotatably inserted with a driven gear 24, and the driven gear 24 is engaged with the L-shaped rack 34 to convert the linear motion of the L-shaped rack 34 into rotation, driving the driven shaft 23 and the driven swing arm 25 to move, and the pair of driven gears 24 are meshed and connected, and each driven shaft 23 is A driven swing arm 25 is fixedly provided at the outer end. The driven swing arm 25 swings under the drive of the driven shaft 23, and cooperates with the limit pin 26 through the elliptical pin hole to drive the hollow slider 22 to move. An elliptical pin hole is opened at the outer end of each driven swing arm 25. A limit pin 26 is fixedly provided at the middle of the outer side surface of each hollow slider 22. The outer ends of the limit pins 26 are slidably engaged in the elliptical pin holes on the same side. The limit pins 26 connect the hollow slider 22 and the driven swing arm 25, and convert the swing of the driven swing arm 25 into the linear motion of the hollow slider 22. A pair of second rails 18 are fixedly provided in the middle and upper part of the trapezoidal slot 21. The second rails 18 cooperate with the rectangular slider 33 to provide a sliding track for the rectangular slider 33 to ensure the stability of the movement of the rectangular slider 33. A vertically distributed rectangular slider 33 is slidably engaged between the pair of second rails 18. The rectangular slider 33 slides on the second rails 18 to drive the T-shaped torsion bar 36 and related components to move, thereby realizing the tightening operation of the battery 40. A T-shaped torsion bar 36 is rotatably inserted in the middle of the top surface of the rectangular slider 33. The T-shaped torsion bar 36 drives the fixed sleeve 39 and related components to move by rotating and moving up and down, thereby realizing the tightening operation of the battery 40. The fixing sleeve 39 is concentrically fixed to the middle part of the T-shaped torsion bar 36. The fixing sleeve 39 cooperates with the first T-shaped pin 19 through the L-shaped slot 38 to limit the movement trajectory of the T-shaped torsion bar 36, so as to achieve the fastening and limiting of the battery 40. The outer surface of the fixing sleeve 39 is provided with an L-shaped slot 38. The middle and upper part of the trapezoidal slot 21 is fixed with the first T-shaped pin 19. The outer end of the first T-shaped pin 19 is slidably inserted in the L-shaped slot 38. The first T-shaped pin 19 cooperates with the L-shaped slot 38 to limit the movement of the fixing sleeve 39 and the T-shaped torsion bar 36, so as to ensure that the fastening operation of the battery 40 is accurately performed. A pair of symmetrically distributed L-shaped racks 34 are fixed on both sides of the rectangular slider 33. The L-shaped racks 34 convert the linear motion of the rectangular slider 33 into the rotation of the driven gear 24, thereby realizing the linkage operation of the battery 40 fastening related components. Each L-shaped rack 34 is meshed and connected with the driven gear 24 on the same side. A positioning block 35 is fixed at the bottom end of each L-shaped rack 34. When the L-shaped rack 34 moves, the positioning block 35 abuts against the tension spring 37, compresses the tension spring 37, and plays a positioning and limiting role at the same time. A tension spring 37 is fixed on the bottom surface of each positioning block 35. The bottom end of each tension spring 37 abuts against the inner bottom wall of the trapezoidal slot 21. The tension spring 37 provides an upward elastic force, which can assist the L-shaped rack 34 in resetting after movement, and at the same time buffer the movement impact to a certain extent.

[0023] Specifically, the working principle and operation method of the present invention are as follows: Step 1: Before use, the piston spring 41, the fixed spring 42, and the fixed spring 42 are all in an open state, and the rotating swing arm 30 is parallel to the trapezoidal side plate 12; The battery 40 is placed centrally on the loading plate 4. Under the action of the battery 40's own weight, the battery 40 drives the loading plate 4, the four trapezoidal legs 3, and the shock absorbing plate 2 to move downward, thereby driving the fixed slide bar 6 to slide downward along the second slide hole, so that the fixed spring 42 is compressed and deformed; Under the hinged action of the first U-shaped ear seat 7 and the first single ear seat, and under the hinged action of the second U-shaped ear seat 10 and the second single ear seat, the piston slide rod 8 and the piston slide block 9 are driven to slide outward along the piston slide cylinder 11, so that the piston spring 41 is compressed and deformed; Step 2: When the trapezoidal leg 3 moves downward, under the joint hinge action of the first pin shaft, the second pin shaft and the hinge connecting rod 15, the trapezoidal side plate 12 is driven to translate toward the battery 40, and the positioning slide bar 13 is driven to slide inward along the third slide hole, and the plurality of elastic balls 16 are driven to abut against the corresponding side surfaces of the battery 40, thereby forming a preliminary clamping and fixing of the battery 40; Step 3: Press the T-shaped torsion bar 36 and the fixing sleeve 39 downward to drive the L-shaped slide groove 38 to slide downward along the first T-shaped pin 19, and drive the rectangular slider 33 and a pair of L-shaped racks 34 to slide downward along a stack of second rails 18. The L-shaped rack 34 drives the positioning block 35 downward to press against the tension spring 37, so that the tension spring 37 is compressed and deformed. The L-shaped rack 34 then meshes and drives the driven gear 24, the driven shaft 23, and the driven swing arm 25 to swing downward. Under the limiting action formed by the limiting pin 26 and the elliptical pin hole, the hollow slider 22 is driven to slide downward along the pair of first rails 17. The hollow slider 22 drives the rotating slide rod 27 to slide downward along the first slide hole through a pair of limiting rings 28. The bending slot 32 on the limiting sleeve 29 slides downward along the second T-pin shaft 20, and the bending slot 32 and the second T-pin shaft 20 form a limiting effect, and drive the limiting sleeve 29 and the rotating slide bar 27 to move downward along the hollow slider 22, and then rotate along the fourth slide hole, and drive the rotating swing arm 30 and the elastic pressure block 31 to move synchronously, and then drive the elastic pressure block 31 to rest against the top surface of the battery 40, and then rotate the T-shaped torsion bar 36 and the fixing sleeve 39, so that the first T-pin shaft 19 is limited and engaged at the bending part in the L-shaped slot 38, so as to clamp and fix the battery 40 again.

[0024] The present invention uses multiple shock-absorbing structures and flexible clamping designs to effectively absorb vibrations, prevent displacement of the battery 40, and achieve convenient operation and automatic resetting. Its stability and reliability are significantly improved, ensuring the safety and service life of the battery 40 during ship operation, and is suitable for complex marine environments.
