Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0037] Embodiment 1: This embodiment provides a shock-proof fastening device for a new energy ship battery. Refer to Figures 1-9 , specifically, it includes an open box 1. A number of evenly distributed elliptical through holes are opened on the front, rear, left, and right four side surfaces of the open box 1. The elliptical through holes can reduce the overall weight of the device, play a role in buffering vibration to a certain extent, facilitate air circulation, and be conducive to heat dissipation. The open design is convenient for the installation and maintenance of internal components; a shock-absorbing plate 2 is suspended in the middle and lower part of the open box 1. The shock-absorbing plate 2 provides a supporting plane for the battery 40 below, and can effectively buffer the vibration from below through connection with the piston shock-absorbing assembly, protecting the battery 40 from vibration impact. The shock-absorbing plate 2 is connected to the open box 1 through the piston shock-absorbing assembly;

[0038] To ensure the stability of the placement of the battery 40, four circularly distributed trapezoidal legs 3 are fixedly provided on the top surface of the open box 1. The trapezoidal legs 3 support the load-carrying plate 4 and the battery 40, transferring the weight of the battery 40 to the open box 1. At the same time, its trapezoidal structure can increase stability, and a load-carrying plate 4 is fixedly provided on the top end surfaces of the four trapezoidal legs 3. The load-carrying plate 4 provides a placement platform for the battery 40;

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] In the specific implementation process, Figure 4 and Figure 5As shown, fixed inclined plates 5 are fixedly provided at the middle and lower parts of the four corners inside the open box 1. The fixed inclined plates 5 cooperate with the fixed sliding rods 6 and the fixed springs 42 to further enhance the damping effect, and at the same time play a certain limiting and supporting role for the damping plate 2. Second sliding holes are formed at the outer ends of each fixed inclined plate 5. Fixed sliding rods 6 are fixedly provided at the four corners of the bottom surface of the damping plate 2. 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 damping plate 2 and the battery 40. The bottom end of each fixed sliding rod 6 is slidably inserted into the corresponding second sliding hole on one side, and the upper half of each fixed sliding rod 6 is sleeved with a fixed spring 42. The upper and lower ends of each fixed spring 42 respectively abut against the damping plate 2 and the fixed inclined plate 5. The fixed spring 42 absorbs vibration energy through elastic deformation, assists the piston damping assembly, and enhances the overall damping performance;

[0044] The piston damping assembly includes a piston sliding rod 8 and a piston sliding cylinder 11. First U-shaped ear seats 7 are fixedly provided at the four corners of the top surface of the damping plate 2. A first single ear seat is hinged 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 sliding rod 8. The first U-shaped ear seats 7 at the four corners of the top surface of the damping plate 2 are connected to the piston sliding rod 8 through the first single ear seats;

[0045] Second U-shaped ear seats 10 are fixedly provided at the middle and lower parts of the four corners inside the open box 1. A second single ear seat is hinged in the opening of each second U-shaped ear seat 10. The outer end of each second single ear seat is fixedly provided with a piston sliding cylinder 11. A piston slider 9 is slidably arranged inside each piston sliding cylinder 11. The second U-shaped ear seats 10 at the middle and lower parts of the four corners inside the open box 1 are connected to the piston sliding cylinder 11 through the second single ear seats;

[0046] The outer end of each piston sliding rod 8 is slidably inserted into the outer port of the corresponding piston sliding cylinder 11 on one side, and the outer end of each piston sliding rod 8 is fixedly connected to the corresponding piston slider 9. The outer section of each piston sliding rod 8 is sleeved with a piston spring 41, and the two ends of each piston spring 41 respectively abut against the piston sliding cylinder 11 and the piston slider 9. When the device is vibrated, the piston sliding rod 8 and the piston slider 9 slide in the piston sliding cylinder 11, and the piston spring 41 undergoes elastic deformation. The piston spring 41 absorbs and buffers vibration energy through its expansion and contraction, reduces the vibration transmitted to the battery 40, and improves the anti-vibration effect of the battery 40.

[0047] Embodiment 2: On the basis of Embodiment 1, this embodiment further includes:

[0048] In the specific implementation process, such as Figure 6 and Figure 7As shown, a pair of third sliding holes are provided on each of the four side surfaces of the open box 1. At the two corners at the bottom of the outer side surface of each trapezoidal side plate 12, a positioning sliding rod 13 is fixedly provided. When the trapezoidal side plate 12 is translated, the positioning sliding rod 13 slides along the third sliding hole, playing a role in limiting and guiding, ensuring the accuracy of the movement of the trapezoidal side plate 12. The outer end of each positioning sliding rod 13 is slidably inserted into the third sliding hole on the corresponding side;

[0049] The hinge assembly includes hinge connecting rods 15. A T-shaped seat 14 is fixedly provided in the middle of the bottom surface of the trapezoidal side plate 12. A pair of first pin shafts penetratingly distributed are rotatably inserted in the upper middle part and the bottom end part of the T-shaped seat 14. At both ends of each first pin shaft, a pair of hinge connecting rods 15 distributed in parallel are fixedly provided. The T-shaped seat 14 in the middle of the bottom surface of the trapezoidal side plate 12 is connected to a pair of hinge connecting rods 15 distributed in parallel through the first pin shaft;

[0050] A pair of second pin shafts penetratingly distributed are rotatably inserted in the upper middle part and the bottom end part of the trapezoidal leg 3. Both ends of each second pin shaft are fixedly connected to the bottom ends of a pair of hinge connecting rods 15 on the same side respectively. The hinge assembly enables the trapezoidal side plate 12 to flexibly translate towards the battery 40 along with the movement of the trapezoidal leg 3, realizing the clamping action on the battery 40, and the connection is firm and the movement is reliable.

[0051] Embodiment Three: On the basis of Embodiment Two, this embodiment further includes:

[0052] In the specific implementation process, as Figure 8 and Figure 9 shown, two pairs of first rail tracks 17 are fixedly provided on both sides of the trapezoidal slot 21. The first rail tracks 17 cooperate with the hollow slider 22 to provide a sliding track for the hollow slider 22, ensuring the smoothness and accuracy of the movement of the hollow slider 22. A vertically distributed hollow slider 22 is slidably clamped between each pair of first rail tracks 17. The hollow slider 22 drives the rotating slide rod 27 to move by sliding on the first rail track 17;

[0053] A fourth sliding hole is provided in the middle of the hollow slider 22. The middle part of the rotating slide rod 27 is rotatably inserted through the fourth sliding hole. A pair of limiting retaining rings 28 are fixedly provided in the middle of the rotating slide rod 27, and the pair of limiting retaining rings 28 are distributed on the upper and lower sides of the hollow slider 22. The limiting retaining rings 28 can prevent the rotating slide rod 27 from detaching from the hollow slider 22, and at the same time allow the rotating slide rod 27 to rotate within the hollow slider 22;

[0054] The limiting mechanism includes a limiting sleeve 29 and a second T-shaped pin 20. A concentrically fixed limiting sleeve 29 is sleeved on the upper middle part of the rotating slide bar 27. A bent chute 32 is formed on the outer surface of the limiting sleeve 29. The upper half of the bent chute 32 is a vertical slot, and the lower half is arc-shaped. A pair of second T-shaped pins 20 are fixedly arranged at the two corners of the inner top of the trapezoidal slot 21. The outer ends of the second T-shaped pins 20 are slidably engaged in the corresponding bent chute 32 on one side. During the movement of the rotating slide bar 27, through the cooperation of the bent chute 32 and the second T-shaped pins 20, the movement track of the rotating slide bar 27 is restricted, so that it first slides downward and then rotates, accurately realizing the fastening operation of the battery 40.

[0055] 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. The driven shafts 23 support the driven gears 24 and transmit the rotation of the driven gears 24 to drive the movement of the driven swing arms 25. A driven gear 24 is rotatably inserted in the middle of each driven shaft 23. The driven gear 24 meshes with the L-shaped rack 34 to convert the linear movement of the L-shaped rack 34 into rotation, driving the movement of the driven shafts 23 and the driven swing arms 25. And the pair of driven gears 24 are meshed and connected. A driven swing arm 25 is fixedly arranged at the outer end of each driven shaft 23. The driven swing arm 25 swings driven by the driven shaft 23 and drives the hollow slider 22 to move through the cooperation of the elliptical pin hole and the limiting pin 26. An elliptical pin hole is formed at the outer end of each driven swing arm 25. A limiting pin 26 is fixedly arranged in the middle of the outer side of each hollow slider 22. The outer ends of the limiting pins 26 are slidably engaged in the elliptical pin holes on the same side. The limiting pin 26 connects the hollow slider 22 and the driven swing arm 25, converting the swing of the driven swing arm 25 into the linear movement of the hollow slider 22;

[0056] A pair of second rail guides 18 are fixedly installed in the upper middle part of the trapezoidal slot 21. The second rail guides 18 cooperate with the rectangular slider 33 to provide a sliding track for the rectangular slider 33, ensuring the stability of the movement of the rectangular slider 33. And a vertically distributed rectangular slider 33 is slidably engaged between the pair of second rail guides 18. The rectangular slider 33 slides on the second rail guides 18, driving the T-shaped torsion bar 36 and related components to move, realizing the fastening operation of the battery 40. The middle part of the top surface of the rectangular slider 33 is rotatably inserted with a T-shaped torsion bar 36. The T-shaped torsion bar 36 drives the fixed sleeve 39 and related components to move through rotation and vertical movement, realizing the fastening and limiting operations of the battery 40. A concentrically fixedly connected fixed sleeve 39 is sleeved on the middle part of the T-shaped torsion bar 36. The fixed sleeve 39 cooperates with the first T-shaped pin shaft 19 through the L-shaped sliding groove 38 to limit the movement track of the T-shaped torsion bar 36, realizing the fastening and limiting of the battery 40. An L-shaped sliding groove 38 is opened on the outer surface of the fixed sleeve 39. The first T-shaped pin shaft 19 is fixedly installed in the upper middle part of the trapezoidal slot 21. The outer end of the first T-shaped pin shaft 19 is slidably inserted into the L-shaped sliding groove 38. The first T-shaped pin shaft 19 cooperates with the L-shaped sliding groove 38 to limit the movement of the fixed sleeve 39 and the T-shaped torsion bar 36, ensuring the accurate implementation of the fastening operation of the battery 40;

[0057] A pair of symmetrically distributed L-shaped racks 34 are fixedly installed on both sides of the rectangular slider 33. The L-shaped racks 34 convert the linear movement of the rectangular slider 33 into the rotation of the driven gear 24, realizing the linkage operation of the components related to the fastening of the battery 40. Each L-shaped rack 34 is meshed and connected with the driven gear 24 on the same side. A positioning stop block 35 is fixedly installed at the bottom end of each L-shaped rack 34. When the L-shaped rack 34 moves, the positioning stop block 35 abuts against the tension spring 37, compressing the tension spring 37, and playing a role of positioning and limiting at the same time. A tension spring 37 is fixedly installed on the bottom surface of each positioning stop 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 to reset after movement and buffer the movement impact to a certain extent.

[0058] Specifically, the working principle and operation method of the present invention are as follows:

[0059] 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;

[0060] Place the battery 40 in the middle on the load plate 4. Under the action of the self-weight of the battery 40, the battery 40 drives the load plate 4, the four trapezoidal legs 3, and the shock-absorbing plate 2 to move downward, and then drives the fixed sliding rod 6 to slide downward along the second sliding hole, causing the fixed spring 42 to be compressed and deformed;

[0061] Under the hinge action of the first U-shaped ear seat 7 and the first single ear seat, and under the hinge action of the second U-shaped ear seat 10 and the second single ear seat, the piston slide rod 8 and the piston slider 9 are driven to slide outward along the piston slide cylinder 11, causing the piston spring 41 to be compressed and deformed;

[0062] Step 2, when the trapezoidal leg 3 moves downward, under the combined 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 towards the battery 40, and the positioning slide rod 13 is driven to slide inward along the third slide hole, and a number of elastic balls 16 are driven to abut against the corresponding side surface of the battery 40, forming a preliminary clamping and fixing of the battery 40;

[0063] Step 3, press down the T-shaped torsion bar 36 and the fixed sleeve 39, drive the L-shaped sliding groove 38 to slide downward along the first T-shaped pin shaft 19, and drive the rectangular slider 33 and a pair of L-shaped rack bars 34 to slide downward along a pair of second rail tracks 18. The L-shaped rack bar 34 drives the positioning block 35 to press downward against the tension spring 37, causing the tension spring 37 to be compressed and deformed;

[0064] The L-shaped rack bar 34 then meshes to drive 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 shaft 26 and the elliptical pin hole, the hollow slider 22 is driven to slide downward along a pair of first rail tracks 17. The hollow slider 22 drives the rotating slide rod 27 to slide downward along the first slide hole through a pair of limiting retaining rings 28;

[0065] The bending sliding groove 32 on the limiting sleeve 29 slides downward along the second T-shaped pin shaft 20.
