Description

Technical Field

[0001] This utility model relates to the field of non-Newtonian fluid protective beam technology, and in particular to a non-Newtonian fluid protective beam. Background Technology

[0002] In the field of safety protection for automobiles and other vehicles, a non-Newtonian fluid protective beam is a new type of protective device that integrates the characteristics of non-Newtonian fluids with mechanical structure design. Its core principle is to utilize the viscosity change characteristics of non-Newtonian fluids under different external forces to achieve a dynamic response of flexible buffering under low impact and rigid protection under high impact. Through the synergistic effect of the outer shell and internal support structure with the non-Newtonian fluid, the external impact force is dispersed, absorbed and transmitted, thereby reducing the damage to the protected object.

[0003] Early crash beams were made of metal, with a rigid beam structure and fixed brackets connecting to the vehicle body. The rigid beam resisted and dispersed impact force through its own deformation, while the fixed brackets transmitted the force to the vehicle frame. Since the rigid beam's energy absorption relied entirely on rigid deformation, its impact energy absorption efficiency was low. In a strong collision, it would break due to localized stress concentration, providing insufficient cushioning protection for occupants. To address these issues, current technology uses non-Newtonian fluid as the core material and designs a suitable cavity structure, solving the problems of heavy weight and low energy absorption efficiency of traditional metal crash beams. This achieves a combination of lightweight and high-efficiency energy absorption. However, in actual use, when the non-Newtonian fluid is stationary in the cavity, particle sedimentation occurs due to the density difference between the particles and the base fluid. When impacted, the fluid in the high-density area at the bottom becomes enriched with particles, resulting in more drastic viscosity changes and a tendency for energy absorption overload. This leads to uneven absorption and dispersion of the overall impact force, reducing the protective effect and failing to meet user needs. Summary of the Invention

Multiple disturbance blades are connected to the sliding rod and are arranged sequentially up and down inside the protective shell. A drive assembly is provided on the rear side of the support shell.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please refer to Figure 3 , Figure 4 and Figure 6 An embodiment of this utility model is provided: a non-Newtonian fluid protection beam, including a support frame 1, which provides stable support for a support shell 2 and a protective shell 3 and transmits the impact force to the vehicle frame. The support shell 2 is fixedly connected to the bottom front side of the support frame 1. The support shell 2 provides rotational support for the rotating shaft 401 of the stirring mechanism 4 and serves as the mounting base for the protective shell 3. The protective shell 3 is fixedly connected to the top of the support shell 2. The protective shell 3 seals and contains the non-Newtonian fluid. The stirring mechanism 4 is provided inside the protective shell 3. Mounting mechanisms 5 are provided on both the left and right sides of the support frame 1.

[0038] The agitation mechanism 4 includes a rotating shaft 401, which is rotatably mounted on the inner wall of the support shell 2 using a common method, such as a shaft and hole connection. The rotating shaft 401 is connected to a drive assembly 408, which transmits power to a cam 402 to achieve the conversion of circular motion. A cam 402 is fixedly connected to one side of the rotating shaft 401, and the cam 402 converts the circular motion of the rotating shaft 401 into the linear reciprocating motion of the slide rod 404. The protective shell 3 has a sliding hole 403, which connects to the support shell. A slide rod 404 is slidably connected to the protective shell 3. The slide rod 404 drives the disturbance blades 407 to move up and down, directly disturbing the non-Newtonian fluid. A limit plate 405 is connected to the bottom end of the slide rod 404. A spring 406 is sleeved on the slide rod 404. The spring 406 elastically clamps between the limit plate 405 and the protective shell 3. The cam 402 abuts against the limit plate 405. Thus, when the cam 402 rotates, the limit plate 405 can move up and down, thereby driving the slide rod 404 to move up and down. Multiple disturbance blades 407 are connected to the slide rod 404. The multiple disturbance blades 407 are arranged sequentially up and down and are located inside the protective shell 3. A drive assembly 408 is provided on the rear side of the support shell 2.

[0039] The drive assembly 408 includes a guide rod 4081, one end of which is fixedly connected to the rotating shaft 401. The guide rod 4081 converts the linear motion of the slide plate 4084 into the oscillation of the rotating shaft 401. A groove 4082 is provided at the rear end of the support shell 2. The groove 4082 guides the sliding trajectory of the front end of the guide rod 4081 to ensure the stability of the motion conversion. One end of the guide rod 4081 is slidably connected to the inner wall of the groove 4082. One end of the guide rod 4081 passes through the groove 4082 and slides on the inner wall of the groove 4082 when the guide rod 4081 is subjected to force. A cavity 4083 is provided on the front side of the support frame 1. The slide plate 4084 is slidably connected to the inner side of the cavity 4083. The slide plate 4084 acts as a force transmitter for the spring 4085. The carrier converts the vibration energy from the car's bumps into mechanical energy. Multiple springs 4085 are fixedly connected to opposite sides of the cavity 4083. The springs 4085 store and release energy, providing the restoring force for the reciprocating motion of the slide plate 4084. The other ends of the multiple springs 4085 are fixedly connected to the upper and lower ends of the slide plate 4084, respectively. A limit groove 4086 is opened on one side of the guide rod 4081. A linkage rod 4087 is fixedly connected to the front side of the slide plate 4084. The bottom side of the linkage rod 4087 is slidably connected to the inside of the limit groove 4086. The linkage rod 4087 moves up and down with the slide plate 4084 and transmits force to the guide rod 4081 through the limit groove 4086, causing the guide rod 4081 to drive the rotating shaft 401 to swing back and forth.

[0040] A guide rod 8 is fixedly connected to the top of the inner wall of cavity 4083. The guide rod 8 restricts the slide plate 4084 to move only along the axial direction, ensuring that the force direction of the guide rod 4081 is consistent with the movement direction. The bottom end of the guide rod 8 passes through the top of the slide plate 4084 and is fixedly connected to the bottom of the inner wall of cavity 4083.

[0041] The position of the limiting plate 405 corresponds to the position of the cam 402. The limiting plate 405 increases the force-bearing area at the bottom of the slide bar 404 to ensure that the thrust of the cam 402 is transmitted evenly. The multiple disturbance blades 407 have different angles, which makes the disturbance effect on non-Newtonian fluids better.

[0042] Specifically, the device is securely mounted on the car via a support frame 1. A protective shell 3 forms a closed cavity containing a non-Newtonian fluid. When the car encounters bumps during driving, spring 4085 vibrates up and down. The sliding plate 4084 within the cavity, under the elastic action of spring 4085, reciprocates vertically along guide rod 8. Guide rod 8 restricts the trajectory of sliding plate 4084, allowing only vertical displacement. This vertical movement of sliding plate 4084 causes linkage rod 4087 to move synchronously. The bottom left side of linkage rod 4087 is slidably connected to slide groove 4082. The vertical displacement of linkage rod 4087 is converted into the reciprocating oscillation of guide rod 4081. The oscillation of guide rod 4081 drives rotating shaft 401 to rotate slightly back and forth, while cam 402 periodically oscillates with the oscillation of rotating shaft 401. As the car moves, the slide bar 404, under the elastic force of the spring 406, slides downward along the sliding hole 403. The limiting plate 405 at the bottom of the slide bar 404 corresponds to the position of the cam 402. The periodic oscillation of the cam 402 pushes the limiting plate 405, causing the slide bar 404 to move upward against the elastic force of the spring 406. This causes multiple disturbance blades 407 on the outer wall of the protective shell 3 to tumble up and down in the cavity, disturbing the non-Newtonian fluid and promoting the uniform distribution of particles in the base fluid. This effectively absorbs and disperses the impact force, ensuring the stability of the protective effect. When the car is impacted, the non-Newtonian fluid in the protective shell 3, due to the uniform distribution of particles and the consistent viscosity change in each area, can synchronously and efficiently absorb and disperse the impact force, avoiding the problems of energy overload caused by bottom particle accumulation and insufficient energy absorption at the top in traditional structures, thus ensuring the stability of the protective effect.

[0043] Please refer to Figure 1 , Figure 2 and Figure 5The mounting mechanism 5 includes two side plates 501. The side plates 501 connect the support frame 1 to the vehicle mounting position. The adjacent sides of the two side plates 501 are fixedly connected to the left and right rear ends of the support frame 1, respectively. The front side of the two side plates 501 is provided with multiple mounting slots 502 to provide a precise sliding track for the slider 503, restricting the slider 503 to move only in the vertical direction, avoiding horizontal offset or rotation during adjustment, and ensuring the stability of the installation position. The slider 503 is slidably connected to one side of the multiple mounting slots 502, and the installation height is finely adjusted by sliding itself to adapt to the height deviation of the mounting position of different vehicle models. The front end of the multiple sliders 503 is threaded with bolts 504, and the bolts 504 fasten the sliders 503 to the vehicle mounting holes.

[0044] The rear ends of multiple sliders 503 are fixedly connected to washers 15, and the rear ends of multiple bolts 504 pass through the front ends of the corresponding sliders 503 and washers 15 respectively.

[0045] Please continue to refer to Figure 1 , Figure 2 and Figure 3 Specifically, the two side plates 501 of the mounting mechanism 5 form the basic structure for docking with the vehicle mounting position. The upper and lower ends of the front end of the side plate 501 are provided with mounting grooves 502, which provide a track for the slider 503 to slide up and down. The slider 503 can freely adjust its height along the longitudinal direction of the mounting groove 502 to adapt to the vertical size differences of different vehicle mounting positions. The front end of the slider 503 is used as a positioning locking part by a threaded bolt 504. When the position needs to be adjusted, the bolt 504 is loosened, and the slider 503 can slide flexibly in the mounting groove 502. When the slider 503 moves to the height aligned with the vehicle mounting position, the bolt 504 passes through the slider 503 and cooperates with the reserved hole of the vehicle mounting position. The contact area is increased by the shim 15 to ensure the stability of the connection and prevent loosening due to vibration.

[0046] Reference Figure 3 and Figure 4 A fixed post 9 is fixedly connected to one side of the inner side of the protective shell 3 to provide a path for the floating plate 10 to slide down. The floating plate 10 is slidably connected to the top of the outer wall of the fixed post 9. The floating plate 10 floats on the top of the non-Newtonian fluid by buoyancy. An alarm 11 is fixedly connected to the middle of the outer wall of the fixed post 9. The alarm 11 is triggered to remind that the leakage of the non-Newtonian fluid exceeds the safety value.

[0047] A guide groove 12 is provided on one side of the inner side of the protective shell 3. The guide groove 12 is used to guide and limit the floating plate 10 so that the floating plate 10 can only move up and down. One end of the floating plate 10 is slidably connected to the inner side of the guide groove 12.

[0048] The bottom of the protective shell 3 has a groove 6, and a sealing ring 7 is fixedly connected inside each of the two grooves 6.

[0049] The top of the inner wall of the protective shell 3 is provided with an inspection hole 14, which is used to inspect the fluid inside the protective shell 3. The top of the outer wall of the protective shell 3 is provided with a cap 13, which is threaded to the inner wall of the inspection hole 14 and is used for sealing.

[0050] Specifically, the buoyancy of the non-Newtonian fluid inside the protective shell 3 causes the floating plate 10 to float on top of the fluid. When the non-Newtonian fluid leaks or decreases, the floating plate 10 slides down along the fixed column 9. When the floating plate 10 contacts the alarm 11, it triggers the alarm, indicating that the leakage of non-Newtonian fluid inside the protective shell 3 exceeds the safe value. The sealing ring 7 in the groove 6 at the bottom inside the protective shell 3 fits tightly against the inner wall of the protective shell 3, maintaining the sealing of the protective shell 3 during installation and adjustment to prevent leakage of non-Newtonian fluid. Unscrewing the cap 13 allows for inspection of the inside of the protective shell 3.

[0051] Working principle: The device is fixed to the car by the support frame 1. The protective shell 3 forms a closed cavity to contain non-Newtonian fluid. When the car moves and causes bumps, the second spring 4085 is vibrated. The slide plate 4084 in the cavity 4083 moves up and down along the guide rod 8 under the elastic force of the second spring 4085. The guide rod 8 restricts the slide plate 4084 to only move vertically. The up and down movement of the slide plate 4084 drives the linkage rod 4087 to move synchronously. Since the bottom left side of the linkage rod 4087 is slidably connected to the slide groove 4082, its up and down displacement is converted into the reciprocating swing of the guide rod 4081. The guide rod 4081 simultaneously drives the rotating shaft 4 01 makes a small-amplitude reciprocating rotation, and the cam 402 swings back and forth with the rotating shaft 401. The slide rod 404 inside the protective shell 3 slides down along the slide hole 403 under the elastic action of the spring 406. The limiting piece 405 at the bottom of the slide rod 404 corresponds to the position of the cam 402. When the cam 402 swings back and forth, it will periodically push the limiting piece 405, so that the slide rod 404 overcomes the elastic force of the spring 406 and moves upward. This will drive the multiple disturbance blades 407 on its outer wall to flip up and down inside the protective shell 3, forming a disturbance to the non-Newtonian fluid, so that the particles are evenly distributed in the base liquid, efficiently absorbing and dispersing the impact force, and ensuring stable protection effect.

[0052] Furthermore, the two side plates 501 of the mounting mechanism 5 are the basic structure for docking with the vehicle mounting position. The mounting grooves 502 opened at the upper and lower ends of the front side of the side plate 501 provide a track for the slider 503 to slide up and down. The slider 503 can freely adjust its height along the longitudinal direction of the mounting groove 502 to adapt to the vertical dimension deviation of different vehicle mounting positions. The bolt 504 threaded to the front end of the slider 503 is a positioning and locking part. When the position needs to be adjusted, the bolt 504 is loosened, and the slider 503 can slide flexibly in the mounting groove 502. After the slider 503 moves to the height aligned with the vehicle mounting position, the bolt 504 passes through the slider 503 and engages with the reserved hole of the vehicle mounting position. The gasket 15 increases the contact area to ensure a firm connection and prevent loosening caused by vibration.
