Description

Technical Field

[0001] This utility model relates to the field of sealing and vibration reduction technology for mining electric vehicles, and in particular to a sealing, vibration reduction and noise reduction structure for mining electric vehicles. Background Technology

[0002] Sealed shock absorbers for mining electric vehicles are a type of sealed shock absorber used in mining transport vehicles.

[0003] The sealed shock absorbers of mining electric vehicles play a role in cushioning the vehicle's structural sinking when transporting materials underground. Due to the complex underground environment, when the vehicle is fully loaded and passes through a pit, the shock absorbers reach their maximum descent limit. At this time, the shock absorbers will generate huge noise due to the internal impact, and the noise will be transmitted to the cab. Due to long-term driving, the noise will have a certain impact on the driver's hearing. The existing noise reduction methods use cab sound insulation to reduce the transmission of noise, but they cannot reduce noise at the source. Therefore, it will affect the driver's judgment of other sounds, which can easily lead to dangerous situations while driving.

[0004] Therefore, we provide a sealed vibration damping and noise reduction structure for mining electric vehicles. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example 1: A sealed, shock-absorbing, and noise-reducing structure for mining electric vehicles, such as... Figure 1 - Figure 5 As shown, it includes a sealing and vibration damping 1. A power rod 2 is fixedly installed on the outer side of the upper half of the sealing and vibration damping 1. There are at least two power rods 2, which are symmetrical. A rotating shaft 3 is fixedly installed on the outer side of the lower half of the two power rods 2. There are at least two sets of rotating shafts 3, with two in each set. A support rod 4 is rotatably connected to the outer side of the rotating shaft 3. A sliding shaft 6 is rotatably connected to the end of the support rod 4 away from the rotating shaft 3. A sound insulation component 7 is inserted into the sliding shaft 6.

[0025] When the sealing damper 1 moves downward under the pressure from above, the power rod 2 moves downward under the drive of the sealing damper 1. At the same time, the support rod 4 begins to rotate under the support of the rotating shaft 3, and also begins to rotate under the support of the sliding shaft 6. Due to the downward movement of the power rod 2, the support rod 4 begins to move downward. When the support rod 4 begins to move downward, the sliding shaft 6 follows the movement of the support rod 4 and begins to move downward. When the sliding shaft 6 begins to move downward, it pulls the sound insulation component 7. At this time, the sound insulation component 7 is pulled and begins to rotate towards the center point of the sealing damper 1. When the sealing damper 1 reaches its maximum sinking point, the sound insulation component 7 is closed. At the same time, the upper half of the power rod 2 is located outside the sound insulation component 7, and the lower half of the power rod 2 and the support rod 4 are located inside the sound insulation component 7. When the sealing damper 1 begins to move upward, the power rod 2 begins to move upward. Pulling the support rod 4 upwards causes the end of the support rod 4 near the power rod 2 and the power shaft 3 to begin rotating and moving upwards. Simultaneously, the other end of the support rod 4 and the sliding shaft 6 begin rotating. As one end of the support rod 4 moves upwards, the support rod 4 begins to unfold to both sides. At this time, the sliding shaft 6, pushed by the support rod 4, begins to drive the sound insulation component 7 to rotate. The sound insulation component 7 then rotates away from the center point of the sealing and vibration damping 1. When the sealing and vibration damping 1 returns to its initial state, the sound insulation component 7 also returns to its initial state. At this point, the noise reduction work for the impact noise of the sealing and vibration damping is completed. By setting the sound insulation component 7, it can isolate noise during the impact of the sealing and vibration damping 1, achieving a noise reduction effect and improving the noise reduction effect of the sealing and vibration damping. By setting the support rod 4, the sound insulation component 7 can perform closing and unfolding actions, isolating noise and achieving a noise reduction effect, thereby improving the noise reduction effect of the sealing and vibration damping.

[0026] like Figure 1 - Figure 5 As shown, a movable groove 10 is provided on one side of the upper half of the sound insulation component 7, and sliding grooves 9 are provided on opposite sides of the inner wall of the movable groove 10. A sliding plate 8 is provided on one side of the sliding shaft 6.

[0027] A spring 11 is fixedly connected to the side of the sliding plate 8 away from the sliding groove 9, and the end of the spring 11 away from the sliding plate 8 is fixedly connected to the inner wall of the moving groove 10.

[0028] The support rod 4 has a placement groove 5 on one side, and the sound insulation component 7 has a storage groove 14 on the outside. There are at least two sets of storage grooves 14, and two in each set.

[0029] As the sound insulation component 7 moves with the support rod 4, it begins to rotate towards the center point of the sealing and damping 1. When the sound insulation component 7 is about to close, the lower half of the power rod 2 enters the placement groove 5 on the support rod 4. Simultaneously, the power rod 2 continues to move downwards, and the support rod 4 continues to pull the sound insulation component 7 to close. At this time, the other end of the support rod 4 away from the power rod 2 moves into the moving groove 10. When the support rod 4 is parallel to the moving groove 10, the power rod 2 continues to move downwards, and the support rod 4 continues to move into the moving groove 10. At this time, the support rod 4 pushes the sliding shaft 6 to slide in the sliding groove 9 on the moving groove 10. Simultaneously, the sliding shaft 6 pushes the sliding plate 8 to move in the sliding groove 9. The sliding plate 8 is pushed by the sliding shaft 6, and the sliding plate 8 applies a pushing force to the spring 11. The spring 11 then contracts. Simultaneously, the support rod 4 drives the power rod 2 into the moving groove 10, and the sealing and damping 1 sinks to its lowest point, and the sound insulation component 7 completes to close. When the sealing and damping 1 begins to rise... The power rod 2 begins to move upwards, and simultaneously moves from inside the placement slot 5 to the outside. At the same time, the support rod 4, pulled by the power rod 2, begins to move from inside the moving slot 10 to the outside. At this point, the spring 11 loses its thrust and begins to push the sliding plate 8, causing it to push the sliding shaft 6 back to its initial position. Meanwhile, the power rod 2 continues to move upwards, and the support rod 4 unfolds to both sides. The sound insulation component 7, pushed by the support rod 4, begins to unfold away from the center of the sealing and vibration damping 1. When the sealing and vibration damping 1 returns to its initial state, the sound insulation component 1 also returns to its initial state. By setting the placement slot 5 and the moving slot 10, the power rod 2 and support rod 4 can be stored, allowing the sound insulation component 7 to close, thus improving its sound insulation effect and enhancing the noise reduction effect of the sealing and vibration damping 1. By setting the sliding slot 9, the support rod 4 can be stored inside the moving slot 10, further improving the closing effect of the sound insulation component 7 and further enhancing the noise reduction effect of the sealing and vibration damping 1.

[0030] like Figure 1 - Figure 5 As shown, the lower half of the sealing and damping 1 is fixedly installed with a support shaft 13. There are at least two support shafts 13, which are symmetrically distributed. The outer sides of the two support shafts 13 are rotatably connected to support plates 12. One side of the support plate 12 is fixedly connected to one side of the sound insulation component 7.

[0031] A limiting block 15 is fixedly installed on the outer side of the lower half of the sound insulation component 7. There are at least two limiting blocks 15. A limiting frame 16 is provided on the outer side of the two limiting blocks 15. The limiting frame 16 is fixedly connected to the outer side of the lower half of the sound insulation component 7. The limiting block 15 is located inside the limiting frame 16.

[0032] When the sound insulation component 7 begins to close, it drives the support plate 12 to rotate under the support of the support shaft 13. At the same time, the limiting block 15 moves within the limiting frame 16 along with the sound insulation component 7. When the sound insulation component 7 unfolds away from the center point of the sealing and vibration damping 1, it drives the support plate 12 to rotate under the support of the support shaft 13. Simultaneously, the limiting block 15 moves within the limiting frame 16 along with the sound insulation component 7. After the sound insulation component 7 has finished unfolding, the limiting block 15 moves to the inner wall of the limiting frame 16 and fits against it. At this time, the limiting frame 16 restricts the movement of the limiting block 15 and also restricts the unfolding of the sound insulation component 7. By setting the limiting frame 16, the unfolding of the sound insulation component 7 can be restricted, preventing the sound insulation component 7 from rotating excessively, which would prevent the sound insulation component 7 from accurately closing again and thus failing to complete noise reduction. This improves the noise reduction effect of the sealing and vibration damping 1.

[0033] Example 2: A sealed, shock-absorbing, and noise-reducing structure for mining electric vehicles, such as... Figure 1 - Figure 5 As shown, the sound insulation component 7 has a vibration isolation layer 701 inside, a sound insulation layer 702 on one side of the vibration isolation layer 701, a sound absorption layer 703 on one side of the sound insulation layer 702, and a protective layer 704 on one side of the sound absorption layer 703.

[0034] When the loud impact noise of the sealed vibration damper 1 is transmitted through vibration, the vibration damping layer 701 on the sound insulation component 7, which is attached to its surface, reduces the vibration. The weakened noise continues to be transmitted into the sound insulation component 7. When the noise passes through the vibration damping layer 701 and reaches the sound insulation layer 702, the thick material of the sound insulation layer 702 isolates the noise, weakening it again. The noise then passes through the sound insulation layer 702 and enters the sound absorption layer 703. The sound absorption layer 703 contains sound-absorbing material, and the noise is absorbed by the sound absorption layer 703. At the same time, the protective layer 704 isolates external debris to prevent it from scratching the sound insulation component 7. By using the vibration damping layer 701, the sound insulation layer 702, and the sound absorption layer 703 in combination, the noise transmission is reduced, and the noise is isolated and absorbed, thereby further improving the noise reduction effect of the sealed vibration damper 1.

[0035] Working principle: When the sealing damper 1 moves downward, the power rod 2 moves downward, the support rod 4 starts to rotate, and simultaneously the support rod 4 moves downward, the sliding shaft 6 moves downward, the sound insulation component 7 rotates, the support plate 12 starts to rotate, the limit block 15 moves, the lower half of the power rod 2 enters the placement groove 5, the support rod 4 moves into the moving groove 10, the sliding shaft 6 pushes the sliding plate 8 to move, the spring 11 retracts, and the support rod 4 drives the power rod 2 into the moving groove 10. When the sealing damper 1 reaches its maximum sinking point, the sound insulation component 7 closes completely, and the vibration isolation layer 701... To reduce vibration, the sound insulation layer 702 isolates noise, the sound absorption layer 703 absorbs noise, and the protective layer 704 isolates external debris. When the sealing damping 1 begins to move upward, the power rod 2 moves upward and outward from the placement groove 5. The support rod 4 moves outward from the moving groove 10, the spring 11 stretches, the sliding shaft 6 returns to its initial position, the support rod 4 moves upward, the sound insulation component 7 rotates, the support plate 12 begins to rotate, and the limit block 15 begins to move. When the sealing damping 1 returns to its initial state, the sound insulation component 7 stops unfolding, and noise reduction is completed.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
