Description

Technical Field

[0001] This application relates to the technical field of automotive parts, and in particular to an automotive seat fixing clip. Background Technology

[0002] Automotive components are the basic units that constitute the overall function of a car, covering the engine, chassis, body, electrical system and new energy / intelligent driving related components. Car seat fixing clips are a type of automotive component. Their functions include fixing the seat, ensuring the seat is stable while driving, folding or unfolding the seat when unlocked, fixing child seats in conjunction with ISOFIX or LATCH systems, and adjusting seat functions such as heating and cooling in high-end models.

[0003] Car seat fixing technology is a crucial aspect of automobile manufacturing and modification. Common car seat fixing methods include: bolt fixing: directly connecting the seat bracket to the vehicle frame with bolts. The advantage is high connection strength, but the disadvantage is time-consuming installation and the need for specialized tools; welding fixing: welding the seat bracket to the vehicle frame as a single unit. The advantage is good stability, but the disadvantage is difficulty in disassembly and maintenance; and clip-on fixing: using plastic or metal clips for quick installation. The advantage is ease of operation, but the disadvantage is weak tensile strength and susceptibility to wear and deformation after long-term use. Therefore, it is necessary to propose a car seat fixing clip to solve these problems. Summary of the Invention

[0004] To address the shortcomings of existing car seat fixing clips that use bolts, welding, and snap-on fasteners, this application provides a car seat fixing clip.

[0005] This application provides a car seat fixing clip, which adopts the following technical solution: A car seat fixing buckle includes a U-shaped fixing base, a buckle body inserted into the U-shaped fixing base, mounting brackets fixedly installed on both the left and right sides of the buckle body, a second spring fixedly installed on the outer side of the mounting bracket, a locking block fixedly connected to the outer side of the second spring, the outer side of the locking block extending out of the interior of the buckle body, slots opened on both the left and right sides of the U-shaped fixing base, the locking block and the slots engaging with each other, a guide rod fixedly installed on the inner side of the locking block inside the second spring, the guide rod penetrating the interior of the mounting bracket.

[0006] Through the interaction of the locking block, the second spring, and the locking slot, during the process of inserting the buckle body into the U-shaped fixing seat from top to bottom, when the locking block moves to the inner side of the locking slot, the elastic force of the second spring can push the locking block to the left and right, causing it to move out of the buckle body and then into the locking slot. This quickly engages and fixes the buckle body inside the U-shaped fixing seat, improving the installation efficiency of the fixing buckle. It replaces the bolts, welding, and snap-fit ​​connections using plastic structures used in existing technologies, solving the problems of time-consuming bolt fixing installation and the need for special tools; welding... The fixed fasteners are difficult to disassemble and are not conducive to later maintenance; the snap-on fasteners have weak tensile strength and are prone to wear and deformation after long-term use. However, through the assembly combination, by pressing the locking block inward, the locking block retracts into the locking body, and the locking body can be pulled upward to remove the locking body from the inside of the U-shaped fixing seat. This enables quick assembly, disassembly and maintenance of the U-shaped fixing seat and the locking body; the installation of a guide rod can guide and limit the sliding trajectory of the locking block driven by the second spring, preventing the extension and retraction position of the second spring from deviating and affecting the use of the locking block.

[0007] A further improvement of the technical solution of this application is that: a push plate is slidably connected to the bottom of the U-shaped fixing seat, and several first springs are fixedly installed on the bottom of the push plate. The bottom of the first springs is fixedly connected to the inner wall of the U-shaped fixing seat, and the upper surface of the push plate is pressed against the buckle body.

[0008] The above technical solution utilizes the cooperation between the push plate and the first spring. After the locking block is pushed into the interior of the buckle body, the elastic force of the first spring can generate a pushing force on the push plate to the top, thereby causing the buckle body to move upward a short distance, thus misaligning the position of the locking block with the locking slot. This allows the operator to free up their hand to pull the buckle body upward, improving the efficiency of disassembling the buckle body.

[0009] A further improvement of the technical solution of this application is that: the left and right outer sides of the card block are provided with inclined surfaces that slope inward toward the bottom.

[0010] By adopting the above technical solution, the outer surface of the locking block is set as an inclined surface to facilitate the locking block to be aligned and locked into the interior of the stop block, thereby reducing resistance. This eliminates the need for operators to manually push the locking block inward and move the locking body during the installation process, reducing operation steps and improving work efficiency.

[0011] A further improvement of the technical solution of this application is that a stop is provided on the inner side of the mounting bracket, and the stop is fixedly connected to the inner surface of the guide rod.

[0012] By adopting the above technical solution, the maximum distance that the locking block can move outward can be limited by setting a stop, preventing the guide rod from detaching from the interior of the mounting bracket and affecting the sliding operation of the locking block.

[0013] A further improvement of the technical solution of this application is that: both sides of the buckle body at the bottom of the mounting bracket are fixedly installed with clips, and the clips are made of plastic.

[0014] The above technical solution involves installing a clip. After the clip body is inserted into the U-shaped fixing seat, the clip itself is made of plastic and has a certain deformation and rebound capability. Therefore, the clip can engage with the inner wall of the clip body, thereby reinforcing the installation of the clip body to a certain extent and improving the stability of the installation between the clip body and the U-shaped fixing seat.

[0015] A further improvement to the technical solution of this application is that a bevel is formed on the outer surface of the bottom of the card strip.

[0016] By adopting the above technical solution, by opening a bevel on the outer side of the bottom of the clip, the clip can be easily aligned and snapped into the interior of the U-shaped fixing seat, reducing the resistance of the clip sliding downward, thereby ensuring normal installation between the clip body and the U-shaped fixing seat.

[0017] A further improvement of the technical solution of this application is that: several balls are rolled inside the buckle body on both sides of the front and rear sides of the card strip, and the outer surface of the balls is in contact with the inner wall of the U-shaped fixing seat.

[0018] The above technical solution involves setting several balls, which can separate part of the outer surface of the buckle body from the interior of the U-shaped fixing seat, and the balls can roll along the inner wall of the buckle body, thereby reducing wear between the buckle body and the U-shaped fixing seat and extending their service life.

[0019] A further improvement of the technical solution of this application is that a baffle is fixedly installed on the periphery of the U-shaped fixing seat, the baffle is inclined and located on the top of the block.

[0020] By adopting the above technical solution, the installation of an inclined baffle can, to a certain extent, shield and protect the position of the locking block from the outside, reducing the possibility that the operator may accidentally touch the locking block and push it into the buckle body, thereby improving the stability of the installation between the buckle body and the U-shaped fixing seat.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. This application provides a car seat fixing buckle. By setting a locking block, a second spring, and a locking groove, when the locking block moves to the inner position of the locking groove, the second spring can push the locking block out and engage it in the locking groove, thereby quickly engaging and fixing the buckle body inside the U-shaped fixing seat. This improves the installation efficiency of the fixing buckle and replaces the bolts, welding, and snap-fit ​​connections using plastic structures used in the prior art. It solves the problems of bolt fixing installation being time-consuming and requiring special tools; welding fixing being difficult to disassemble and not conducive to later maintenance; and snap-fit ​​fixing having weak tensile strength and being prone to wear and deformation after long-term use. Furthermore, by pressing the locking block inward, it retracts into the inside of the buckle body, allowing the buckle body to be removed from the inside of the U-shaped fixing seat, thereby realizing the rapid assembly, disassembly, and maintenance of the U-shaped fixing seat and the buckle body.

[0022] 2. This application provides a car seat fixing buckle. By setting a push plate and a first spring, after the buckle block is pushed into the inside of the buckle body, the first spring pushes the push plate upward to move the buckle body upward a short distance, which can offset the position of the buckle block from the buckle slot, thereby making it easier for the operator to free up their hand to pull the buckle body upward, thus improving the disassembly efficiency of the buckle body.

[0023] 3. This application provides a car seat fixing buckle. By setting the outer surface of the buckle block as an inclined surface, the buckle block can be easily aligned and snapped into the inside of the stop block, reducing resistance. The operator does not need to manually push the buckle block inward during the installation of the buckle body, thereby reducing operation steps and improving work efficiency.

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] Example 1 See Figure 1 , Figure 2 and Figure 3 This application provides a car seat fixing buckle, including a U-shaped fixing base 1, a buckle body 2 inserted into the U-shaped fixing base 1, mounting brackets 6 fixedly installed on both the left and right sides of the buckle body 2, a second spring 10 fixedly installed on the outer side of the mounting bracket 6, a locking block 4 fixedly connected to the outer side of the second spring 10, the outer side of the locking block 4 extending out of the interior of the buckle body 2, slots 13 are opened on both the left and right sides of the U-shaped fixing base 1, the locking block 4 and the slots 13 engage with each other, a guide rod 12 is fixedly installed on the inner side of the locking block 4 inside the second spring 10, and the guide rod 12 passes through the interior of the mounting bracket 6.

[0028] In this embodiment, through the cooperation between the locking block 4, the second spring 10, and the locking groove 13, during the process of inserting the buckle body 2 from top to bottom into the U-shaped fixing base 1, when the locking block 4 moves to the inner side of the locking groove 13, the elastic force of the second spring 10 can push the locking block 4 to the left and right, causing it to move out of the buckle body 2 and then into the locking groove 13. This quickly engages and fixes the buckle body 2 inside the U-shaped fixing base 1, improving the installation efficiency of the fixing buckle. It replaces the bolts, welding, and snap-fit ​​connections using plastic structures used in the prior art, solving the problems of time-consuming bolt fixing installation and the need for special equipment in the prior art. Tools; welding fixation is difficult to disassemble and not conducive to later maintenance; snap-on fixation has weak tensile strength and is prone to wear and deformation after long-term use. In addition, by using an assembly combination, the snap-on block 4 is pressed inward, causing the snap-on block 4 to retract into the snap-on body 2, and the snap-on body 2 can be pulled upward to remove the snap-on body 2 from the inside of the U-shaped fixing seat 1. This enables the U-shaped fixing seat 1 and the snap-on body 2 to be quickly assembled, disassembled and repaired. The guide rod 12 can guide and limit the sliding trajectory of the second spring 10 driving the snap-on block 4, preventing the extension and retraction position of the second spring 10 from deviating and affecting the use of the snap-on block 4.

[0029] Example 2 See Figure 2 , Figure 4 and Figure 5 Based on Embodiment 1, this application provides a technical solution: Preferably, a push plate 7 is slidably connected to the bottom of the U-shaped fixing seat 1, and a plurality of first springs 8 are fixedly installed on the bottom of the push plate 7. The bottom of the first springs 8 is fixedly connected to the inner wall of the U-shaped fixing seat 1, and the upper surface of the push plate 7 is pressed against the buckle body 2; the left and right outer sides of the buckle block 4 are provided with inclined surfaces that slope inward toward the bottom; a stop block 11 is provided on the inner side of the mounting bracket 6, and the stop block 11 is fixedly connected to the inner surface of the guide rod 12. Both sides of the buckle body 2 at the bottom of the mounting bracket 6 are fixedly installed with clips 5, which are made of plastic; the outer surface of the bottom of the clips 5 is beveled.

[0030] In this embodiment, through the cooperation between the push plate 7 and the first spring 8, after the locking block 4 is pushed into the interior of the locking body 2, the elastic force of the first spring 8 can generate a pushing force on the push plate 7 to the top, thereby causing the locking body 2 to move upward a small distance, offsetting the position of the locking block 4 from the locking slot 13, thus freeing the operator's hand to pull the locking body 2 upward, improving the disassembly efficiency of the locking body 2; by setting the outer surface of the locking block 4 as a slope, the locking block 4 can be aligned and locked into the interior of the stop block 11, reducing resistance, eliminating the need for the operator to manually push the locking block 4 inward during the installation of the locking body 2, and then move the locking body 2, reducing operation steps and improving work efficiency; by setting the stop block 11, the maximum distance that the locking block 4 moves outward can be limited, preventing the guide rod 12 from disengaging from the interior of the mounting bracket 6, which would affect the sliding operation of the locking block 4; By installing the clip 5, where the clip body 2 is inserted into the U-shaped fixing seat 1, the clip 5 itself is made of plastic and has a certain deformation and rebound capability. Therefore, the clip 5 can engage with the inner wall of the clip body 2, thereby reinforcing the installation of the clip body 2 to a certain extent and improving the stability of the installation between the clip body 2 and the U-shaped fixing seat 1. By opening a bevel on the outer side of the bottom of the clip 5, it is easy to align the clip 5 and engage it with the inside of the U-shaped fixing seat 1, reducing the resistance of the clip 5 sliding downward, thereby ensuring normal installation between the clip body 2 and the U-shaped fixing seat 1.

[0031] Example 3 See Figure 3 , Figure 4 and Figure 5 Based on embodiment 2, this application provides a technical solution: preferably, a plurality of balls 9 are rolled inside the buckle body 2 on both sides of the front and rear sides of the card strip 5, and the outer surface of the balls 9 is in contact with the inner wall of the U-shaped fixing seat 1; a baffle 3 is fixedly installed on the periphery of the U-shaped fixing seat 1, the baffle 3 is inclined and located on the top of the card block 4.

[0032] In this embodiment, by setting a plurality of ball bearings 9, which can separate part of the outer surface of the buckle body 2 from the interior of the U-shaped fixing seat 1, and the ball bearings 9 can roll along the inner wall of the buckle, the wear between the buckle body 2 and the U-shaped fixing seat 1 is reduced, thereby extending their service life; by installing an inclined baffle 3, the position of the buckle block 4 can be shielded and protected from the outside to a certain extent, reducing the possibility that the operator may accidentally touch the buckle block 4 and push it into the buckle body 2, thereby improving the stability of the installation between the buckle body 2 and the U-shaped fixing seat 1.

[0033] The working principle of this car seat fixing clip is explained in detail below.

[0034] like Figures 1-5 As shown, the operator inserts the buckle body 2 into the U-shaped fixing seat 1 from the top. The inclined surface of the buckle block 4 contacts the inner wall of the U-shaped fixing seat 1, causing the buckle block 4 to automatically retract into the buckle body 2 under the pressure of the U-shaped fixing seat 1. The inclined surface of the buckle strip 5 also fits against the inner wall of the U-shaped fixing seat 1, and the U-shaped fixing seat 1 can squeeze the buckle strip 5, causing the buckle strip 5 to move and deform, and engage with the inner wall of the U-shaped fixing seat 1. The bottom of the buckle body 2 fits against the upper surface of the push plate 7 and presses the push plate 7 downward. When the locking block 4 moves to the inside of the slot 13, the second spring 10 pushes the locking block 4 outward, causing the locking block 4 to engage in the slot 13, and at the same time, a "click" sound is emitted to indicate that the installation is in place; by pressing the locking block 4 inward, the locking block 4 is fully inserted into the locking body 2 as indicated by the hand, and at the same time, the first spring 8 pushes the push plate 7 upward, causing the locking body 2 to move upward a small distance, and then the second spring 10 locks the locking block 4 out of the slot 13. Then the operator frees up his hand to pull the locking body 2 upward, and disassembles the locking body 2 from the U-shaped fixing seat 1.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
