Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing equipment technology, and in particular to a magnetically assisted positioning seat injection hook. Background Technology

[0002] Currently, in the field of seat installation and fixation, traditional methods mostly use connection structures such as bolts and clips. Bolt connections require pre-drilling and tightening with tools, which is cumbersome and can damage the seat structure to some extent; while clip connections are convenient to install, they are prone to loosening and falling off under large external forces or long-term vibration, which cannot guarantee the reliability and stability of the seat fixation. As industries such as automobiles and office furniture increasingly demand higher efficiency and safety in seat installation, magnetic positioning technology is gradually being applied to seat fixation. However, existing magnetic seat fixation devices have many shortcomings: some products rely solely on a single magnetic structure, resulting in limited adsorption force and a lack of effective restraint on the magnetic blocks, making them prone to displacement or even detachment under external force; other products, while incorporating hook components, suffer from poor hook layout, failing to adapt to force requirements in different directions, leading to poor fixation.

[0003] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Existing devices mostly rely on screws, clips, or adhesive for fixation, requiring tools and time-consuming positioning; disassembly can easily damage the seat surface. Some magnetic products use simple magnet stacking, resulting in unstable attraction and easy displacement after installation. Most magnetic devices lack limiting structures, allowing the magnets to easily slide or detach due to external forces. Some products use glue to fix the magnets, which are prone to aging and falling off after long-term use, posing a safety hazard. Utility Model Content

[0004] To overcome the technical defects of the existing technology, this utility model provides a magnetically assisted positioning seat injection hook.

[0005] The technical solution adopted by this utility model is: a magnetic suction-assisted positioning seat injection hook, including a base fabric, an injection hook assembly is provided on the top of the base fabric, and a magnetic suction mechanism is provided on the bottom of the base fabric; The magnetic attraction mechanism includes a neodymium iron boron magnet for attracting a metal seat, a silicone base for accommodating the neodymium iron boron magnet, and a limiting component for restricting the vertical movement of the neodymium iron boron magnet. A positioning hole is provided through the top of the silicone base for movably fitting the neodymium iron boron magnet. A limiting block is fixedly connected to the top of the neodymium iron boron magnet, and the limiting block has an umbrella-shaped structure, used to cooperate with the limiting component to fix the neodymium iron boron magnet. The neodymium iron boron magnet attracts the metal seat frame through strong magnetism, achieving rapid positioning and providing initial fixing force.

[0006] Preferably, the limiting component includes an inverted U-shaped limiting rod fixedly connected to the top of the silicone base, a positioning ring fixedly installed on the top of the silicone base, a limiting cable fixedly connected inside the positioning ring, and a buffer pad fixedly installed between the inverted U-shaped limiting rod and the base fabric. The inverted U-shaped limiting rod is fixed to the top of the silicone base and, together with the positioning holes, forms a limiting hole structure. Together with the limiting cable, it forms a U-shaped groove, constraining the vertical displacement of the limiting block while allowing for horizontal fine-tuning.

[0007] Preferably, the limiting cable includes two parallel elastic cables, and the limiting cable passes through a limiting hole formed by an inverted U-shaped limiting rod and a silicone base. The limiting cable, the two parallel elastic cables, passes through the limiting hole and restricts the vertical movement of the magnetic block through elastic force and geometric grooves, thus taking into account both fixation and adaptability.

[0008] Preferably, the inverted U-shaped limiting rod and the positioning hole are spaced apart on the top of the silicone base, and the inverted U-shaped limiting rod and the positioning hole are distributed in a dot matrix pattern. The positioning ring is fixed to the silicone base to support the limiting cable.

[0009] Preferably, the top of the umbrella-shaped limiting block passes through a square-shaped slot formed by an inverted U-shaped limiting rod and a limiting cable.

[0010] Preferably, the injection hook assembly includes a first base fixedly installed on the top of the base fabric and a second base fixedly installed on the top of the base fabric, wherein a first hook body is fixedly connected to the top of the first base and a second hook body is fixedly connected to the top of the second base.

[0011] Preferably, the first base and the second base are spaced apart on the base fabric, and the opening direction of the first hook and the opening direction of the second hook form a 90° angle.

[0012] The beneficial effects of this utility model are as follows: By setting up components such as neodymium iron boron magnets, silicone bases, limiting blocks, inverted U-shaped limiting rods, and limiting cables, and through the sleeve engagement between the neodymium iron boron magnets and the positioning holes of the silicone base, and the engaging relationship between the limiting blocks and the U-shaped grooves formed by the inverted U-shaped limiting rods and limiting cables, the neodymium iron boron magnets can strongly magnetically attract the metal seat frame, while the limiting components restrict its vertical movement. This achieves the effect of quickly attracting and positioning the metal seat through the magnetic attraction mechanism, and preventing the magnets from falling off, thus realizing a stable and convenient initial positioning of the seat on the metal seat. By setting up components such as a first base, a first hook, a second base, and a second hook, and through the engagement relationship of the first and second hooks being spaced apart on the base fabric with their opening directions at a 90° angle, the first and second hooks can respectively hook and fix the seat fabric or components in different directions. This allows the device to enhance the multi-directional fixing capability of the seat fabric through the orthogonal layout of the injection hook assembly. Combined with the flexible adaptation of the base fabric to the seat surface, the injection hooks achieve a stable and flexible multi-directional positioning and fixing effect on the seat fabric.

[0014] The present invention will be further described below with reference to the accompanying drawings: like Figure 1As shown, this embodiment provides a magnetically assisted positioning seat injection hook, including a base fabric 1, an injection hook assembly 2 on the top of the base fabric 1, and a magnetic attraction mechanism 3 on the bottom of the base fabric 1; the base fabric 1 serves as the basic support, combining flexibility and durability, and can adapt to different seat surface shapes, providing a stable mounting base for the injection hook assembly and the magnetic attraction mechanism 3, ensuring the overall structure works in tandem. Please see Figures 2 to 5 The magnetic attraction mechanism 3 includes a neodymium iron boron magnet 303 for adsorbing a metal seat, a silicone base 301 for accommodating the neodymium iron boron magnet 303, and a limiting component for restricting the vertical movement of the neodymium iron boron magnet 303. A positioning hole 302 is provided through the top of the silicone base 301 for movably fitting the neodymium iron boron magnet 303. A limiting block 304, which has an umbrella-shaped structure, is fixedly connected to the top of the neodymium iron boron magnet 303 to secure it in conjunction with the limiting component. The neodymium iron boron magnet 303 tightly adsorbs the metal seat due to its strong magnetic properties. The silicone base 301 protects the magnet and buffers contact stress. The limiting component, in conjunction with the umbrella-shaped limiting block 304, prevents the magnet from shifting, ensuring stable adsorption and easy disassembly. The limiting assembly includes an inverted U-shaped limiting rod 305 fixedly connected to the top of the silicone base 301, a positioning ring 306 fixedly installed on the top of the silicone base 301, a limiting cable 307 fixedly connected inside the positioning ring 306, and a buffer pad 308 fixedly installed between the inverted U-shaped limiting rod 305 and the base fabric 1. The inverted U-shaped limiting rod and the positioning ring 306 form a limiting frame, the limiting cable 307 elastically constrains the lateral displacement of the magnetic block, and the buffer pad 308 alleviates vibration and impact between the seat and the base fabric 1, improving the mechanism's anti-bump performance and service life. The limiting cable 307 includes two parallel elastic cables, and the limiting cable 307 passes through the limiting hole formed by the inverted U-shaped limiting rod 305 and the silicone base 301. The parallel elastic cable structure combines elasticity and tensile strength, forming a flexible constraint within the limiting hole, allowing the magnet to self-adaptively adjust to a small extent, while effectively preventing it from disengaging from the positioning hole 302, thus balancing adsorption stability and installation flexibility. The inverted U-shaped limiting rod 305 and the positioning hole 302 are spaced apart on the top of the silicone base 301, and both the inverted U-shaped limiting rod 305 and the positioning hole 302 are distributed in a dot matrix pattern. The dot matrix layout makes the magnetic attraction force evenly distributed on the seat surface, avoids local stress concentration, adapts to the complex curved surfaces of different metal seats, and enhances the balance and applicability of the overall adsorption system. Furthermore, the top of the umbrella-shaped limiting block 304 passes through a U-shaped slot formed by the inverted U-shaped limiting rod 305 and the limiting cable 307. The umbrella-shaped limiting block 304 and the U-shaped slot fit precisely together, and the inclined structure forms a mechanical lock to prevent the magnetic block from detaching upwards. At the same time, it does not affect its fine adjustment along the axial direction of the positioning hole 302, ensuring the reliable positioning of the magnetic attraction mechanism 3 in dynamic environments. The injection hook assembly 2 includes a first base 201 fixedly installed on the top of the base fabric 1 and a second base 203 fixedly installed on the top of the base fabric 1. A first hook 202 is fixedly connected to the top of the first base 201, and a second hook 204 is fixedly connected to the top of the second base 203. The dual-base design provides diverse connection points. The first hook 202 and the second hook 204 can hook onto the rings or protrusions of different parts of the seat, meeting the needs of multi-angle and multi-method fixation and improving the compatibility of use scenarios.

[0015] The first base 201 and the second base 203 are spaced apart on the base fabric 1, and the opening direction of the first hook 202 forms a 90° angle with the opening direction of the second hook 204. The spaced layout and orthogonal opening design allow the two sets of hooks to form a three-dimensional fixing structure, which can hook planar components parallel to each other and lock columnar components vertically, effectively dealing with complex installation environments and enhancing the product's versatility.

[0016] Car seat cover installation and fixing During the installation of car seat covers, the magnetically assisted positioning seat ejector hooks play an efficient fixing role. First, the base fabric 1 is laid flat on the metal frame surface of the car seat, and the magnetic attraction mechanism 3 at the bottom of the base fabric 1 begins to work. The positioning hole 302 through the silicone base 301 is used to movably engage the neodymium iron boron magnet 303, which is firmly attached to the metal part of the car seat by its strong magnetic force. At this time, the limiting component begins to restrict the up and down movement of the neodymium iron boron magnet 303: the inverted U-shaped limiting rod 305 fixedly connected to the top of the silicone base 301 cooperates with the positioning ring 306, and the limiting cable 307 inside the positioning ring 306 consists of two parallel elastic cables that pass through the limiting hole formed by the inverted U-shaped limiting rod 305 and the silicone base 301. The top of the neodymium iron boron magnet 303 is fixedly connected to the umbrella-shaped limiting block 304, the top of which passes through the square-shaped slot formed by the inverted U-shaped limiting rod 305 and the limiting cable 307, thereby stably fixing the neodymium iron boron magnet 303 on the silicone base 301 and ensuring that the base fabric 1 will not move easily on the car seat. After the base fabric 1 is fixed, the injection hook assembly 2 at the top is used to connect the seat cover. A first base 201 and a second base 203, fixedly installed on the top of the base fabric 1, are respectively connected to a first hook 202 and a second hook 204. Because the first base 201 and the second base 203 are spaced apart on the base fabric 1, and the opening direction of the first hook 202 forms a 90° angle with the opening direction of the second hook 204, they can accommodate fixing points in different directions on the seat cover. The first hook 202 can hook onto the fixing strap at the front of the seat cover, while the second hook 204 can hook onto the fixing ring on the side of the seat cover. Through this multi-angle connection, the seat cover is firmly fixed to the car seat, preventing slippage or displacement during use.

[0017] The implementation principle of a magnetically assisted positioning seat injection hook in this application embodiment is as follows: First, the first hook 202 and the second hook 204 of the injection hook assembly 2 are distributed at orthogonal angles on the top of the base fabric 1. When the device contacts the seat, the operator hooks the two types of hooks to the corresponding structures, such as seat belt fixing points or frame protrusions, according to the installation direction of the seat components. The bidirectional hook design can adapt to tension in different directions simultaneously. Through the flexible deformation of the base fabric, it initially conforms to the seat surface, completing the initial position pre-positioning and providing a reference for subsequent magnetic adsorption. Secondly, when the neodymium iron boron magnet 303 at the bottom of the silicone base 301 approaches the metal parts of the seat along with the base fabric 1, it is quickly attracted to the metal surface, such as the frame or bracket, using strong magnetic force. The magnet moves downward within the positioning hole 302 until it is completely in contact with the metal surface, achieving the initial fixation of the magnetic attraction mechanism 3 to the seat. The diameter of the positioning hole 302 is slightly larger than the diameter of the magnet, allowing the magnet to move slightly in the vertical direction, ensuring close contact during attraction to maximize the magnetic force conduction efficiency. Next, as the magnetic block is attracted downwards, the top umbrella-shaped limiting block 304 moves downwards simultaneously and passes through the slot formed by the inverted U-shaped limiting rod 305 and the limiting cable 307. After the umbrella-shaped structure contacts the inner wall of the slot, the parallel elastic cable of the limiting cable 307 provides lateral restraint, locking the limiting block 304 in the slot and preventing the magnetic block from detaching upwards. The inverted U-shaped limiting rod and the positioning hole 302 are distributed in a dot matrix on the base, and multiple limiting units lock simultaneously to form a mechanical limiting network, ensuring that the magnetic block will not fall off due to vibration or external impact during the attraction state. Next, the spring-loaded structure of the limiting cable 307 has elastic deformation capability. When the seat undergoes slight deformation due to bumps or force, the spring-loaded cable can swing slightly with the magnetic block, avoiding stress concentration caused by rigid connection. The buffer pad 308 between the inverted U-shaped limiting rod and the base fabric 1 is made of soft silicone material, which can effectively absorb vertical impact force and protect the base fabric 1 and the seat surface from scratches. This design allows the device to adapt to a certain degree of tilt or unevenness of the seat surface, ensuring stable adsorption in dynamic environments. Finally, through the bidirectional hooking of the injection hook assembly 2 and the dot matrix adsorption of the magnetic attraction mechanism 3, the equipment forms a stable system of "hook body pre-positioning - magnetic main fixation - mechanical limit assistance - elastic buffer compensation".
