Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing equipment technology, and in particular to a shock-absorbing and noise-reducing seat injection hook. Background Technology

[0002] Traditional seat connection structures often focus on rigid fixation between components, neglecting effective consideration of vibration and noise suppression. In transportation, vibrations from road bumps are transmitted to passengers through the seat, significantly reducing comfort. In office settings, frequent adjustments and movements of posture also cause seat vibrations. These continuous vibrations not only result in a poor riding or user experience but can also cause seat components to gradually loosen, accelerating structural aging and shortening the overall product lifespan. Simultaneously, the noise generated by friction between components due to vibration can disrupt the quiet of an office environment or the interior of a vehicle, affecting user productivity and mood. While existing vibration and noise reduction technologies on the market can alleviate vibration and noise problems to some extent, they still have many limitations. Some technical solutions use outdated vibration-damping materials and structural designs, making it difficult to effectively control both high- and low-frequency vibrations and noise simultaneously. Other technologies, due to their complex structures, result in cumbersome installation processes, requiring highly skilled operators and presenting challenges for subsequent maintenance. Furthermore, these technologies perform poorly in terms of cost control; high production costs significantly hinder market promotion, making it difficult to balance economic efficiency and practicality while ensuring vibration and noise reduction performance. More importantly, existing seat-related devices suffer from low modularity. When a component malfunctions, it is difficult to replace quickly, usually requiring professional personnel, which not only increases maintenance costs but also prolongs product downtime. Furthermore, some seats use relatively fragile fixing methods, such as relying solely on adhesive or having poorly designed force transmission paths. Over long-term use, these fixing methods are prone to failure, further affecting the stability and safety of the seat. The current state of the technology urgently requires a new technical solution to address the problems existing in current seats in terms of shock absorption, noise reduction, structural design, and maintenance. Utility Model Content

[0003] To overcome the technical defects of the existing technology, this utility model provides a shock-absorbing and noise-reducing seat injection hook.

[0004] The technical solution adopted by this utility model is: a shock-absorbing and noise-reducing seat injection hook, including a base fabric assembly, an injection hook assembly is provided on the top of the base fabric assembly, and a shock-absorbing mechanism is provided on the bottom of the base fabric assembly; The shock absorption mechanism includes a silicone liner for supporting the base fabric assembly, a latex liner for shock absorption and noise reduction, a first insert plate and a second insert plate for fixing the latex liner, and a magnetic plate for fixing the first insert plate, the second insert plate and the latex liner by adhesive. Both the first and second insert plates have insert strips fixedly connected to one side, and the insert strips pass through a second locking hole opened on one side of the latex liner.

[0005] Preferably, the base fabric assembly includes a base fabric body for fixing the mounting base and an L-shaped locking block for fixing the latex liner to the second insert plate. A first locking hole is provided through one side of the L-shaped locking block, and the position of the first locking hole corresponds to the position of the second locking hole. The L-shaped locking block cooperates with the insert to achieve mechanical locking of the latex liner and positions the insert through the first locking hole.

[0006] Preferably, the injection hook assembly includes a base fixedly installed on the top of the base fabric body by hot melt adhesive, a first injection hook arranged laterally, and a second injection hook arranged longitudinally, wherein the first injection hook and the second injection hook are both fixedly connected to the top of the base.

[0007] Preferably, the silicone liner is fixedly installed between the base fabric body and the L-shaped card block, and the latex liner is fixedly installed between the base fabric body and the magnetic suction plate by insert strips.

[0008] Preferably, the insert is fixedly sleeved inside the second locking hole and the first locking hole to achieve mechanical locking between the latex liner and the base fabric assembly.

[0009] Preferably, the first insert plate and the second insert plate are fixedly installed between the base fabric body and the silicone backing plate, and both the first insert plate and the second insert plate are fixedly connected to the top of the magnetic suction plate by adhesive.

[0010] Preferably, the magnetic plate is completely bonded to the bottom surface of the latex liner through an adhesive layer, forming a multi-layer shock-absorbing bottom encapsulation structure. The bottom encapsulation shock-absorbing structure of the magnetic plate, along with the bonding plate and the latex liner, enhances the overall integrity and may assist in magnetic positioning.

[0011] Preferably, the silicone liner and the latex liner are arranged in an upper and lower stacked manner, wherein the silicone liner directly contacts the base fabric body and the latex liner directly contacts the magnetic plate.

[0012] The beneficial effects of this utility model are as follows: By setting up components such as a silicone liner, a latex liner, a first insert plate, a second insert plate, and a magnetic plate, and through the overlapping and mating relationship between the silicone liner and the latex liner, the silicone liner can support and absorb high-frequency vibrations through its rigidity, while the latex liner can buffer and reduce low-frequency vibrations through its elasticity. Simultaneously, the first and second insert plates achieve mechanical locking between the latex liner and the base fabric assembly by inserting strips through the second locking holes in the latex liner and the first locking holes in the base fabric assembly. The magnetic plate is completely adhered to the bottom surface of the latex liner through an adhesive layer, forming a multi-layered shock-absorbing structure with a sealed bottom surface. Thus, this device effectively reduces vibrations and noise generated during seat use through the synergistic effect of the silicone and latex liners. By incorporating components such as a base fabric assembly, an injection hook assembly, and a shock-absorbing mechanism, the injection hook assembly is stably mounted on the base fabric body via a hot-melt adhesive connection between the base fabric body and the base of the injection hook assembly, enabling quick connection and removal of the seat fabric. Simultaneously, the L-shaped locking block of the base fabric assembly engages with the first and second insert plates of the shock-absorbing mechanism through through-holes, allowing the shock-absorbing mechanism to be securely mounted on the base fabric assembly via mechanical locking. This achieves the goal of enabling quick connection and removal of seat components via the injection hook assembly, while effectively reducing vibrations and noise generated during seat use through the shock-absorbing mechanism, thus improving the overall performance and comfort of the seat.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings: like Figure 1 As shown, this embodiment provides a shock-absorbing and noise-reducing seat injection hook, including a base fabric assembly 1, an injection hook assembly 2 on the top of the base fabric assembly 1, and a shock-absorbing mechanism 3 on the bottom of the base fabric assembly 1; the base fabric assembly 1 serves as a basic load-bearing body, with the injection hook assembly 2 connected to the top to achieve a flexible connection between the seat and external components, and the shock-absorbing mechanism 3 mounted on the bottom to provide a stable mounting base and a foundation for connecting the shock-absorbing and noise-reducing functions. Please see Figures 2 to 5 The shock absorption mechanism 3 includes a silicone liner 301 that provides support for the base fabric assembly 1, a latex liner 302 for shock absorption and noise reduction, a first insert plate 304 and a second insert plate 305 for fixing the latex liner 302, and a magnetic plate 307 that connects the first insert plate 304, the second insert plate 305 and the latex liner 302 by adhesive. The silicone liner 301 disperses external impact force by elastic deformation, and the latex liner 302 absorbs vibration energy and blocks noise transmission through its flexible material. The insert plate and the magnetic plate 307 work together to form a stable installation structure for the latex liner 302, thereby improving the overall reliability of the shock absorption mechanism 3. Insert strips 306 are fixedly connected to one side of both the first insert plate 304 and the second insert plate 305. The insert strips 306 pass through the second locking hole 303 opened on one side of the latex liner 302. The cooperation between the insert strips 306 and the locking hole forms a mechanical limiting structure to prevent the latex liner 302 from shifting during vibration, ensuring that the shock-absorbing material continues to effectively perform its buffering function and enhancing the connection stability between components. The base fabric assembly 1 includes a base fabric body 101 for fixing the mounting base 201, and an L-shaped locking block 102 for fixing the latex liner 302 to the second insert plate 305. A first locking hole 103 is provided through one side of the L-shaped locking block 102, and the position of the first locking hole 103 corresponds to the position of the second locking hole 303. The base fabric body 101 supports the injection hook assembly 2 and the shock absorption mechanism 3. The L-shaped locking block 102, through its locking hole alignment design, forms a vertical through-type locking with the insert strip 306, reliably fixing the latex liner 302 to the bottom of the base fabric assembly 1, ensuring the integrity of the shock absorption structure.

[0015] The injection hook assembly 2 includes a base 201 fixedly mounted on top of the base fabric body 101 by hot melt adhesive, a first injection hook 202 arranged horizontally, and a second injection hook 203 arranged vertically. Both the first injection hook 202 and the second injection hook 203 are fixedly connected to the top of the base 201. The base 201 provides a rigid mounting base for the injection hooks. The crisscrossing injection hooks form a mesh connection structure, which can adapt to connection objects of different specifications. During the dynamic process of the seat, it can achieve elastic tension and cushioning, reducing noise generated by rigid contact. The silicone liner 301 is fixedly installed between the base fabric body 101 and the L-shaped clamping block 102, while the latex liner 302 is fixedly installed between the base fabric body 101 and the magnetic suction plate 307 via insert strips 306. The silicone liner 301 is sandwiched between the base fabric and the clamping block to evenly transfer the load and suppress high-frequency vibrations, while the latex liner 302 is positioned between the base fabric and the magnetic suction plate 307 via insert strips 306 to attenuate low-frequency vibrations using the material's damping properties, forming a multi-level vibration damping and protection system. The insert 306 is fixedly sleeved inside the second locking hole 303 and the first locking hole 103, achieving mechanical locking between the latex liner 302 and the base fabric assembly 1. The mechanical locking method of the insert 306 passing through the locking hole ensures that the latex liner 302 will not fall off under long-term vibration environment, maintains the effective working position of the shock-absorbing material, and avoids the decrease in noise reduction performance due to component loosening. The first insert plate 304 and the second insert plate 305 are fixedly installed between the base fabric body 101 and the silicone liner 301. Both the first insert plate 304 and the second insert plate 305 are fixedly connected to the top of the magnetic suction plate 307 by adhesive. The insert plates are embedded between the base fabric and the silicone liner 301 to enhance the connection strength between the shock absorption mechanism 3 and the base fabric assembly 1. The magnetic suction plate 307 is bonded to the insert plates by adhesive, providing a flat mounting surface for the latex liner 302 and optimizing the stress uniformity of the shock absorption material. The magnetic plate 307 is fully bonded to the bottom surface of the latex liner 302 via an adhesive layer, forming a multi-layered shock-absorbing structure for bottom surface encapsulation. The adhesive bonding between the magnetic plate 307 and the latex liner 302 not only assists in fixation through magnetic adsorption, but also uses the adhesive layer to fill the tiny gaps, preventing vibration energy from being transmitted to the bottom surface, while simultaneously sealing the shock-absorbing structure to prevent dust and foreign objects from entering and affecting performance. Silicone backing plate 301 and latex backing plate 302 are arranged in an upper and lower stacked manner, with silicone backing plate 301 directly contacting the base fabric body 101 and latex backing plate 302 directly contacting the magnetic suction plate 307. This stacked arrangement allows the silicone and latex materials to work together; the upper silicone layer absorbs high-frequency vibrations, while the lower latex layer cushions the vibrations. Comfortable driving experience of car seats During the assembly of the car seat, the base fabric body 101 of the base fabric assembly 1 is first fixed to the car seat frame via the base 201 of the injection hook assembly 2. The base 201 is firmly connected to the top of the base fabric body 101 with hot melt adhesive. The first injection hook 202 and the second injection hook 203 on its top are arranged in a crisscross pattern, which can be precisely hooked with the seat fabric or other interior parts to achieve stable installation of the base fabric assembly 1. When the car travels on bumpy roads, the vibrations are transmitted through the seat frame to the base fabric assembly 1. At this time, the shock absorption mechanism 3 at the bottom begins to function: the silicone liner 301 directly contacts the base fabric body 101, and with its good elasticity, it first buffers the initial vibration, absorbing some of the energy. Then, the vibration is transmitted to the latex liner 302, which, with its unique flexible structure, further attenuates the vibration and reduces the transmission of vibration to the top of the seat. In this process, the first insert plate 304 and the second insert plate 305 are fixedly installed between the base fabric body 101 and the silicone liner 301. The insert strip 306 on one side of them passes through the second locking hole 303 on one side of the latex liner 302 and the first locking hole 103 of the L-shaped locking block 102 in the base fabric assembly 1, realizing the mechanical locking of the latex liner 302 and the base fabric assembly 1, ensuring that the components will not shift during vibration. At the same time, the magnetic plate 307 is fixedly connected to the first insert plate 304, the second insert plate 305 and the latex liner 302 by adhesive, and is completely attached to the bottom surface of the latex liner 302, forming a multi-layer shock absorption structure bottom encapsulation. This not only enhances the stability of the structure, but also effectively suppresses the noise generated by component friction, providing a quiet and comfortable riding environment for passengers.

[0016] The implementation principle of the shock-absorbing and noise-reducing seat injection hook in this application embodiment is as follows: First, the base fabric body 101 serves as the core carrier, and the base 201 of the injection hook assembly 2 is fixed to the top with hot melt adhesive, forming a connection interface on the seat surface. Simultaneously, at the bottom, an L-shaped locking block 102 rigidly connects to the silicone liner 301, providing a stable mounting surface for the entire shock absorption mechanism 3. The first locking hole 103 on the L-shaped locking block 102 is precisely aligned with the second locking hole 303 of the latex liner 302, providing a structural basis for subsequent mechanical locking. Secondly, the first injection hook 202 arranged laterally and the second injection hook 203 arranged longitudinally form a mesh-like hook structure, with their tips embedded in the velour material of the seat fabric or other components. When the seat is subjected to pressure or vibration, the injection hooks transfer the external load to the base fabric body 101 through the base 201, while the mesh layout disperses stress, avoiding connection failure caused by excessive force at a single point. This process achieves a flexible fastening between the seat injection hooks and the seat surface, ensuring connection stability and reserving buffer space for the lower shock absorption mechanism 3. Next, the silicone liner 301, directly bonded to the base fabric body 101, first bears the load transmitted from the upper layer. Utilizing the high elastic modulus of silicone material, it evenly distributes the concentrated load across the entire bottom surface of the base fabric. Its rigid support effectively suppresses the direct transmission of high-frequency, small-amplitude vibrations, while simultaneously providing a flat space for elastic deformation of the latex liner 302. When the seat is impacted, the silicone liner 301 dissipates some kinetic energy through intermolecular internal friction, completing the attenuation of the first round of vibration energy and reducing the subsequent load pressure on the latex liner 302. Next, the middle latex liner 302, building upon the initial cushioning of the silicone liner 301, utilizes the viscoelastic properties of natural latex for secondary shock absorption. When vibration energy is transmitted to the latex layer, its porous structure undergoes compression-rebound deformation, absorbing vibration energy through the breaking and recombination of molecular chains and converting it into heat dissipation. Simultaneously, the open structure of the latex resonates and absorbs low-to-mid-frequency noise, reducing noise transmission to the human body through the seat. The mechanical locking design of the insert 306, which runs through the locking holes, ensures that the latex liner 302 maintains a stable deformation trajectory during high-frequency vibrations, preventing shock absorption failure due to displacement. Finally, the magnetic plate 307 is completely bonded to the bottom surface of the latex liner 302 through the adhesive layer, forming the bottom layer encapsulation of the shock absorption mechanism 3. The adhesive on its surface not only fixes the first insert plate 304 and the second insert plate 305, but also enhances the integrity of the multi-layer structure through intermolecular forces; if the magnetic plate 307 contains magnetic materials, it can form a weak magnetic attraction fixation with the base fabric assembly 1 or the seat frame, further suppressing the relative sliding between the layers. Ultimately, the rigid support of the silicone, the elastic buffer of the latex, and the encapsulation and locking of the magnetic plate 307 form a "rigid-flexible coupling" synergistic shock absorption system, which allows vibration energy to be reflected and absorbed multiple times at the interface of the multi-layer materials, achieving full-frequency attenuation from high-frequency vibration to low-frequency noise, while maintaining a stable connection to the seat surface through the injection hook assembly 2.

[0017] By mitigating low-frequency impacts and attenuating vibrations across different frequency bands, the overall shock absorption and noise reduction performance of the seat is significantly improved.
