Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing technology, and in particular to a high wear-resistant seat injection hook device. Background Technology

[0002] In the field of seat manufacturing, injection hook devices are commonly used to achieve quick connection and fixation between seat components. However, existing injection hook devices generally suffer from insufficient wear resistance. After long-term use, the hook body is prone to wear, leading to a decline in connection performance. Frequent replacement not only increases maintenance costs but also affects the normal use of the seat. In addition, traditional injection hook and seat installation methods are either unstable, easily loosening in dynamic environments such as vehicle movement, or employ complex installation structures, consuming significant time and labor costs. Furthermore, some injection hooks can easily damage seat fabric during the hooking process, shortening the seat's lifespan.

[0003] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Existing devices mostly use a single-specification hook body, resulting in concentrated wear in the same area, which easily leads to problems such as hook tip breakage and neck deformation. The top and tip of the hook body are mostly designed with right angles or acute angles, resulting in significant stress concentration and easy damage after long-term friction; the neck is of uniform thickness and lacks strength reinforcement design, resulting in weak bending resistance. Utility Model Content

[0004] To overcome the technical defects of existing technologies, this utility model provides a highly wear-resistant seat injection hook device.

[0005] The technical solution adopted by this utility model is: a high wear-resistant seat injection hook device, including a magnetic attraction mechanism, the top of which is provided with a glass fiber reinforced nylon base fabric, and the top of which is provided with an injection hook mechanism;

[0006] An injection hook mechanism includes a first hook assembly and a second hook assembly for improving wear resistance. Both the first hook assembly and the second hook assembly include a base. The height of the base inside the second hook assembly is greater than the height of the base inside the first hook assembly. The base, the first injection hook, and the second injection hook are all integrally formed by a mold.

[0007] Preferably, the first hook assembly and the second hook assembly are arranged in an alternating array, and the base is fixedly connected to the top of the glass fiber reinforced nylon base fabric.

[0008] Preferably, the opening directions of the first injection hook and the second injection hook are opposite, and the first injection hook and the second injection hook are arranged side by side. The tops of the first injection hook and the second injection hook are rounded. The reverse opening of the first / second injection hook is designed for bidirectional hooking, which enhances the gripping firmness with the fabric, prevents one-way detachment, reduces the sharpness of the tip, avoids scratching the seat, and reduces stress concentration to prevent breakage.

[0009] Preferably, the necks of the first and second injection hooks gradually thicken as they extend toward the root, the hook tips of the first and second injection hooks are rounded, and the sides of the first and second injection hooks are provided with ridges.

[0010] Preferably, the magnetic attraction mechanism includes a magnetic plate for adsorbing onto the seat surface, a first adhesive for bonding the magnetic plate to the glass fiber reinforced nylon base fabric, and a second adhesive for bonding the magnetic plate to the glass fiber reinforced nylon base fabric. The first adhesive is composed of multiple arrayed dot-shaped adhesives, and the second adhesive is composed of sheet-shaped adhesives. The magnetic plate is magnetically adsorbed onto the metal surface of the seat, providing initial fixing force and facilitating quick installation and removal.

[0011] Preferably, the first colloid composed of dot-shaped colloids and the second colloid composed of sheet-shaped colloids are arranged alternately.

[0012] Preferably, the first hook assembly and the second hook assembly are arranged in an alternating array, and the base distance between adjacent first hook assemblies and second hook assemblies is 1.5–2.5 mm.

[0013] The beneficial effects of this utility model are as follows: By setting up components such as a magnetic suction plate, a first colloid, a second colloid, and a glass fiber reinforced nylon base fabric, this utility model achieves a stable connection between the magnetic suction plate and the metal surface of the seat through magnetic adsorption. This, combined with the dotted first colloid dispersing adhesive stress and the sheet-like second colloid enhancing overall sealing, allows the magnetic suction mechanism to securely connect the device to the seat surface through a dual-fixation method. This enables the device to adaptively fit the curved surface of the seat through a composite fixing structure, avoiding detachment caused by localized stress or moisture intrusion, thus improving installation convenience and connection reliability. Furthermore, by setting up components such as a first hook assembly, a second hook assembly, a base, and injection hooks, and through the staggered base height design, the reverse-opening injection hook layout, and the rounded corner structure, the injection hook mechanism can disperse stress on the seat fabric or accessories through differentiated hook structures, reducing the risk of hook tip wear and breakage, significantly improving hook firmness and service life through bidirectional hooking and friction strengthening. This allows the device to effectively contact the seat connection parts at high frequencies using an interlaced array of wear-resistant hooks. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] As shown in the figure, this embodiment provides a high-wear-resistant seat injection hook device, including a magnetic suction mechanism 1. A glass fiber reinforced nylon base fabric 2 is disposed on the top of the magnetic suction mechanism 1, and an injection hook mechanism 3 is disposed on the top of the glass fiber reinforced nylon base fabric 2. This structure, through the composite design of the magnetic suction plate 101 and the base fabric, achieves both rapid installation and improved overall structural strength. The glass fiber reinforced nylon base fabric, with its excellent tensile strength and fatigue resistance, can effectively disperse stress concentration in the injection hook mechanism 3 under dynamic loads, extending its service life.

[0022] The injection hook mechanism 3 includes a first hook assembly 31 and a second hook assembly 32 for improving wear resistance. Both the first hook assembly 31 and the second hook assembly 32 include a base 301. The height of the base 301 inside the second hook assembly 32 is greater than the height of the base 301 inside the first hook assembly 31. The base 301, the first injection hook 302, and the second injection hook 303 are all integrally formed by a mold. The differentiated design of the high and low bases 301 optimizes the spatial layout of the hook assembly, allowing hooks of different heights to form a multi-layered gripping structure when in contact with the seat fabric. This enhances the overall grip strength while reducing the wear frequency of individual hooks, achieving a balanced improvement in wear resistance.

[0023] The first hook assembly 31 and the second hook assembly 32 are arranged in an alternating array, and the base 301 is fixedly connected to the top of the glass fiber reinforced nylon base fabric 2. The alternating hook assemblies form a dense and uniform gripping network, which significantly improves the peel strength of the device by increasing the density of contact points with the seat fabric, while avoiding local stress overload caused by concentrated distribution of hooks, and ensuring stable connection performance during long-term use.

[0024] The first injection hook 302 and the second injection hook 303 have opposite opening directions and are arranged side by side, with rounded corners at the top. The reverse opening design allows the hook body to form a two-way gripping force when hooking the fabric, effectively preventing unidirectional fabric slippage; the rounded corner treatment at the top reduces damage to the fabric fibers from the hook tip, lowers the risk of snagging, and balances functionality and fabric protection needs.

[0025] The necks of the first injection hook 302 and the second injection hook 303 gradually thicken towards their roots. The hook tips of the first injection hook 302 and the second injection hook 303 are rounded, and the sides of the first injection hook 302 and the second injection hook 303 are provided with facets. The gradually thickening neck structure enhances the bending strength of the hook body and reduces the risk of breakage due to repeated stress. The facet design on the sides maintains the rigidity of the hook body while further improving the gripping force by increasing the coefficient of friction, making the hook body less prone to loosening during dynamic use.

[0026] The magnetic attraction mechanism 1 includes a magnetic plate 101 for adsorbing onto the seat surface, a first adhesive 102 for bonding the magnetic plate 101 to the glass fiber reinforced nylon base fabric 2, and a second adhesive 103 for bonding the magnetic plate 101 to the glass fiber reinforced nylon base fabric 2. The first adhesive 102 is composed of multiple arrayed dot-shaped adhesives, and the second adhesive 103 is composed of sheet-like adhesives. The composite design of the magnetic plate 101 and the two adhesives achieves a synergistic effect of mechanical adsorption and chemical bonding. The dot-shaped adhesives prevent partial tearing of the base fabric by dispersing stress, while the sheet-like adhesives provide large-area stable bonding, ensuring that the device can maintain a firm fit even in complex vibration environments.

[0027] The first colloid 102, composed of dot-shaped colloids, and the second colloid 103, composed of sheet-shaped colloids, are alternately arranged. This alternating colloid structure optimizes the mechanical properties of the bonding interface. It provides basic adhesive force through the sheet-shaped colloids and absorbs external impact energy through the elastic deformation of the dot-shaped colloids, effectively preventing colloid peeling caused by thermal expansion and contraction or mechanical vibration, and significantly extending the service life of the device.

[0028] The first hook assembly 31 and the second hook assembly 32 are arranged in an alternating array, and the distance between the bases 301 of adjacent first hook assemblies 31 and second hook assemblies 32 is 1.5–2.5 mm. The reasonable design of the base spacing 301 ensures the hook density while providing sufficient embedding space for the fabric fibers, so that the hooks and the fabric form a tight mechanical connection, while avoiding mutual interference caused by excessively dense hooks, ensuring that each hooking action can be completed efficiently.

[0029] Car seat cover quick fixing and removal scenarios

[0030] In routine car seat maintenance, car owners need to clean the fabric seat covers regularly. At this time, a highly abrasion-resistant seat injection hook device can achieve convenient installation and stable fixation of the seat covers:

[0031] Magnetic attraction mechanism 1 positioning and adsorption: First, align the magnetic plate 101 in the magnetic attraction mechanism 1 with the metal parts of the car seat frame, and quickly adsorb and adhere using the magnetic properties of the magnetic plate 101. During this process, the first adhesive 102 and the second adhesive 103 on the surface of the magnetic plate 101 play an auxiliary fixing role—the first adhesive 102, composed of multiple arrayed dot-shaped adhesives, and the second adhesive 103, composed of sheet-like adhesives, are alternately distributed. The dot-shaped adhesives provide initial positioning force at multiple points, while the sheet-like adhesives form a continuous contact adsorption surface, ensuring that the magnetic plate 101 is tightly adhered to the metal frame of the seat and preventing displacement caused by vehicle vibration.

[0032] The injection hook mechanism 3 connects to the seat cover: a velvet material connecting layer matching the injection hook mechanism 3 is pre-set at the bottom of the seat cover. The injection hook mechanism 3 on top of the glass fiber reinforced nylon base fabric 2 is aligned with the velvet layer of the seat cover. The first hook assembly 31 and the second hook assembly 32 achieve high-density contact due to their staggered array arrangement. The base 301 inside the second hook assembly 32 is higher than the base 301 inside the first hook assembly 31, creating a staggered hook distribution. This allows the first injection hooks 302 and 303 at different heights to hook the velvet fibers at different depths. The first injection hook 302 and the second injection hook 303 have opposite opening directions and are arranged side-by-side. Both the top and hook tip are rounded, and the sides have facets. This design ensures smoothness when the hooks pierce the velvet surface and increases friction through the facets, preventing the hooks from coming loose. When the seat cover is pulled by an external force, the structure of the first injection hook 302 and the second injection hook 303, which gradually thickens from the neck to the root, can disperse the stress, prevent the hook body from breaking, and ensure that the seat cover is stable and does not slip during vehicle operation.

[0033] Easy disassembly: When cleaning, simply pull the seat cover vertically upwards and use the separable characteristics of the magnetic mechanism 1 to easily remove the entire device without the need for tools, thus improving maintenance efficiency.

[0034] The implementation principle of a high wear-resistant seat injection hook device in this application embodiment is as follows:

[0035] First, the magnetic attraction mechanism 1 is activated. The magnetic plate 101, using its own magnetism, quickly adheres to the metal parts of the seat, achieving initial fixation of the device. At the same time, the dot-shaped adhesive of the first colloid 102 and the sheet-shaped adhesive of the second colloid 103 work together alternately. The dot-shaped adhesive quickly positions itself, while the sheet-shaped adhesive fills the gaps and enhances the adsorption stability, preventing the device from shifting due to vibration.

[0036] Secondly, the injection hook mechanism 3 comes into play. The first hook assembly 31 and the second hook assembly 32 are staggered in height, and the bases 301 are of different heights, distributed in an alternating array with a spacing of 1.5–2.5 mm. When in contact with the seat accessories, these hooks penetrate the fiber layer of the velvet or napped material at different depths, forming a three-dimensional, interlocking, and tightly meshed structure, which greatly improves the connection strength.

[0037] Next, the optimized design of the hook body itself further enhances the fixing effect. The first injection hook 302 and the second injection hook 303 have opposite opening directions and are side by side, hooking the fiber from both sides to increase the pulling resistance in all directions; the top and hook tip are rounded to reduce the penetration resistance and prevent breakage; the neck is thickened towards the root to disperse the pulling force; the side edges increase friction to hold the fiber in place and prevent it from slipping out, thus comprehensively improving the performance and durability of the hook body.

[0038] Next, the glass fiber reinforced nylon base fabric 2 plays a load-bearing role. It is connected to the base 301 of the injection hook mechanism 3 above and the magnetic suction plate 101 of the magnetic suction mechanism 1 below, forming a stable sandwich structure. The nylon base fabric itself has high toughness and wear resistance, and the strength is further improved after adding glass fiber. It can evenly transmit external forces and avoid damage caused by excessive local stress on the device.

[0039] Finally, all components work together to complete the entire workflow. During installation, the magnetic attraction mechanism 1 quickly positions the device; during connection, the injection hook mechanism 3 tightly engages the attachment; during use, the glass fiber reinforced nylon base fabric 2 conducts force and maintains structural stability; during disassembly, the reversible magnetic attraction allows for easy separation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope of the invention. All such changes and modifications fall within the scope of the invention as claimed, which is defined by the appended claims and their equivalents.
