Description

Technical Field

[0001] This utility model relates to the technical field of automotive shockproof weighing display controllers, specifically a protective mechanism for automotive shockproof weighing display controllers. Background Technology

[0002] The automotive vibration-damping weighing display controller is specifically designed for various commercial vehicles. It can be quickly and directly loaded without modifying the original vehicle structure, and is compatible with various vehicles with 3-6 axles and load capacities of 4-100 tons. Utilizing unique hardware and software technology, the data remains stable and effective even when the vehicle is traveling at speeds of 0-120 km / h, climbing hills, and turning. It can handle the bumps and vibrations of complex road conditions. The internal high-performance digital filter enables accurate and high-speed response in high-vibration environments, allowing for multi-level remote monitoring and providing reliable protection for vehicle transportation safety and cargo weighing. Because vehicles experience significant vibrations and are susceptible to moisture and electromagnetic interference, the protective mechanism reduces wear and tear on the weighing display controller, ensuring weighing accuracy and operational stability, and extending its service life. However, existing protective mechanisms have certain shortcomings.

[0003] For example, CN202421394151.5 describes a car display with a panel anti-damage structure, comprising: a shell, a display body, and protective components. A rear shell is provided on the rear surface of the shell, and the display body is installed on the front surface of the shell. Compared with the prior art, this utility model has the following advantages: By setting protective components, the protective plate combined with the anti-scratch film can directly block external objects from directly colliding and scratching the display body, reducing the risk of damage. Moreover, users can conveniently and quickly install and remove the protective components when needed through the magnetic snap-fit ​​method of magnetic block one and magnetic block two, without affecting the normal maintenance and use of the display body. By setting buffer components, the buffer spring and the buffer can absorb and reduce the impact force received by the protective plate to a great extent, converting and dispersing the impact energy, effectively reducing the impact on the display body, making the display body more resistant to accidental collisions and impacts, and reducing the possibility of damage caused by impact. However, when the protective mechanism is exposed to high-frequency vibration, the shock-absorbing effect of the shock-absorbing components decays quickly, affecting stability. In addition, the protective shell is heavy and weak, increasing the extra load on the vehicle. Long-term dust accumulation can easily clog the heat dissipation holes, affecting the heat dissipation of the equipment.

[0004] Therefore, in view of this, we have studied and improved the existing structure to propose a protective mechanism for a shockproof weighing display controller for automobiles. Utility Model Content

[0005] The purpose of this utility model is to provide a protective mechanism for an automotive shockproof weighing display controller, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective mechanism for an automotive anti-vibration weighing display controller, comprising a controller body and a multi-stage progressive anti-vibration mechanism. The multi-stage progressive anti-vibration mechanism is fixedly connected to the outer surface of the controller body, and the multi-stage progressive anti-vibration mechanism includes a metal spring fixedly connected to the outer surface of the controller body. A helical steel spring is fixedly connected to one side of the metal spring, and a butyl rubber damping rod is fixedly connected inside the helical steel spring. A fluororubber sealing ring is provided at the upper end of the butyl rubber damping rod.

[0007] Preferably, one end of the butyl rubber damping rod is fixedly connected to a protective shell, and a high-strength protection mechanism is fixedly connected inside the protective shell.

[0008] Preferably, the high-strength protection mechanism includes an aluminum alloy reinforcing rib embedded inside the protective shell, and a honeycomb-shaped inner lining is fixedly connected to the outer surface of the aluminum alloy reinforcing rib. The protective shell has heat dissipation holes inside, and a snap-on filter screen is snapped onto one side of the protective shell.

[0009] Preferably, mounting blocks are fixedly connected around the perimeter of the protective housing, and anti-vibration bolts are threaded into the internal parts of the mounting blocks.

[0010] Preferably, a shielding layer is fixedly connected to the outer surface of the protective housing, and a fastening bolt is threadedly connected to the inner surface of the protective housing.

[0011] Preferably, the inner surface of the protective housing is provided with a terminal interface, and a silicone waterproof ring is fixedly connected to the inner wall of the terminal interface.

[0012] Preferably, a display screen is fixedly connected to the surface of the controller body, and a protective plate is rotatably connected to the surface of the controller body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of a multi-level progressive shock absorption mechanism, when high-frequency vibration occurs, the helical steel spring, with its own high-strength elastic characteristics, and the butyl rubber damping block, with the air in its internal honeycomb structure forming a damping effect under vibration compression, attenuates the high-frequency, small-amplitude residual vibration through air friction. Finally, the metal spring sheet, through its own bending deformation, transmits and diffuses the dispersed vibration impact force to the surroundings, so that the vibration energy gradually dissipates in the multi-level buffering process, forming an orderly progressive shock absorption system, which greatly reduces the impact of vibration on the equipment. The fluororubber sealing ring tightly fits the gap to form a sealed cavity to prevent water vapor. Its molecular structure is stable, and it has strong resistance to high and low temperatures. It can withstand extreme temperature differences and maintain its performance in extreme environments.

[0015] 2. This utility model, through the setting of a high-strength protection mechanism, uses high-strength aluminum alloy reinforcing ribs to disperse local impact force to the entire shell, improve the impact resistance of the protective shell edge, and effectively resist collisions and squeezing during vehicle operation. When impacted, the honeycomb unit will absorb most of the impact energy through deformation, converting the instantaneous impact force into material deformation energy, playing a secondary buffering role and preventing vibration from being directly transmitted to the controller body. The snap-on filter screen blocks dust and prevents the heat dissipation holes from reducing heat dissipation efficiency due to dust accumulation. Attached Figure Description

A fluororubber sealing ring 204 is provided at the upper end of the butyl rubber damping rod 203. The helical steel spring 202 is vertically installed between the controller body 1 and the protective housing 3. The fluororubber sealing ring 204 is located in the gap between the controller body 1 and the protective housing 3 to prevent moisture intrusion. The vibration is initially buffered through elastic deformation. The butyl rubber damping rod 203 fills the spring gap through an interference fit, utilizing material damping to attenuate high-frequency vibrations.

[0023] like Figures 3-4 As shown, one end of the butyl rubber damping rod 203 is fixedly connected to the protective shell 3, and a high-strength protection mechanism 4 is fixedly connected inside the protective shell 3.

[0024] Furthermore, mounting blocks 5 are fixedly connected around the protective housing 3, and anti-vibration bolts 6 are threadedly connected inside the mounting blocks 5. A shielding layer 7 is fixedly connected to the outer surface of the protective housing 3, and fastening bolts 8 are threadedly connected to the inner surface of the protective housing 3. Square mounting blocks 5 are welded around the protective housing 3, and anti-vibration bolts 6 pass through their internal threaded holes.
