Technical Field
[0001] This utility model relates to the technical field of automotive seat base frames, specifically to an automotive seat base frame with anti-slip limiting protrusions. Background Technology
[0002] In recent years, with the continuous expansion of the automotive industry, the auto parts market has also shown a booming development trend, and auto parts manufacturing enterprises have ushered in a period of rapid growth. As one of the core components of automobiles, the car seat is the seating component that drivers and passengers come into direct contact with. It is usually connected to the car body through a base, and a lifting and adjustment mechanism is integrated under the base to realize flexible adjustment of the seat height, thereby improving the comfort and adaptability of the ride.
[0003] Existing car seat mounting bases have significant limitations in practical applications: when faced with car seats of different sizes, the base needs to be customized according to the specific seat dimensions, which makes it difficult for the original base to be compatible with the new seat size if the seat needs to be replaced or modified later due to its limited structural adaptability; in addition, traditional bases adopt a fixed area design and only provide positioning constraints in one direction. During the installation process, the unstable positioning reference can easily cause deviations in the spacing of the seat frame, which may ultimately lead to the risk of loose connections or displacement after the seat is installed. Summary of the Invention
[0004] The purpose of this invention is to provide a car seat base frame with anti-slip limiting protrusions to solve the above-mentioned defects caused by the prior art.
[0005] A car seat base frame with anti-slip limiting bosses includes a stress base plate, a convex seat body, an internally threaded tube, and a guide rod. The convex seat body is located directly above the stress base plate. Ventilation holes are evenly spaced on the outer side of the convex seat body. A support mechanism is located directly above the stress base plate. The support mechanism connects the internally threaded tubes, which are evenly spaced at their top ends, to the seat frame and is locked in place by fasteners. An adjustment mechanism is located on the outer side of the convex seat body. The adjustment mechanism adjusts the distance between the two sets of convex seat bodies according to the size of the car seat frame and connects the convex seat body to the outer side of the stress base plate using fastening holes.
[0006] Preferably, the lifting mechanism includes a guide rail, a convex seat, an internally threaded tube, fasteners, a slider bar, and a bearing seat. The bottom end of the guide rail is connected to the top end of the stress substrate. The top end of the convex seat is welded with internally threaded tubes at equal intervals. Fasteners are connected inside the internally threaded tubes. The top end of the slider bar is connected to the bottom end of the convex seat. The bottom end of the stress substrate is connected to the bearing seat.
[0007] Preferably, a slider is fixedly provided at the bottom end of the convex seat, and the slider is slidably connected to the outer side of the guide rail symmetrically arranged on the stress substrate.
[0008] Preferably, the top of the convex seat is provided with several internally threaded tubes at equal intervals, and the internally threaded tubes are rigidly connected to the outer side of the fastener through threaded engagement.
[0009] Preferably, the adjusting mechanism includes a spring post, a guide rod, a fastening hole, an inner guide hole, and a flexible rubber pad. The spring post is located in the middle of the guide rod. The fastening holes are symmetrically located on the outer side of the convex seat. The bottom end of the convex seat is fitted with a flexible rubber pad. Two sets of convex seats are fitted to both the left and right sides of the spring post. The inner guide hole is symmetrically opened through the inside of the convex seat.
[0010] Preferably, the convex seat has symmetrically through-holes on both sides, and the inner guide holes are directly connected to the left and right sides of the guide rod.
[0011] Preferably, a flexible rubber pad is fixedly provided at the bottom end of the convex seat, and the flexible rubber pad is flexibly attached to the top end of the stress substrate.
[0012] Compared with the prior art, the present invention has the following advantages: 1. The slider bar is connected to the outer side of the guide rail through a sliding fit, such as a clearance fit or a low-friction coating treatment, so that the convex seat can slide freely along the axial direction of the guide rail to achieve preliminary position adjustment. The inner guide hole and the guide rod are usually in a sliding fit. This fit allows the convex seat to be adjusted in position along the direction of the guide rod within a certain range, and also guides and constrains the movement of the convex seat.
[0013] 2. The flexible pad fills the tiny gap between the convex seat and the stress base plate through compression deformation, preventing lateral sliding. At the same time, it absorbs impact energy when the vehicle is bumpy, reducing the transmission of vibration to the seat frame. The bottom of the convex seat is fixed with a flexible pad, which is flexibly attached to the top of the stress base plate. The elasticity of the flexible pad can increase its friction during movement, preventing the convex seat from shaking due to insufficient friction during movement. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0017] like Figures 1 to 5 As shown, a car seat base frame with anti-slip limiting bosses includes a stress base plate 1, a convex seat body 3, an internally threaded tube 4, and a guide rod 8. The convex seat body 3 is arranged directly above the stress base plate 1. Ventilation holes 5 are evenly spaced on the outer side of the convex seat body 3. A lifting mechanism 6 is arranged directly above the stress base plate 1. The lifting mechanism 6 connects the internally threaded tube 4, which is evenly spaced at the top, to the seat frame and is locked by fasteners 10. An adjustment mechanism 9 is arranged on the outer side of the convex seat body 3. The adjustment mechanism 9 adjusts the distance between the two sets of convex seat bodies 3 according to the size of the car seat frame. At the same time, fastening holes 11 are used to connect the convex seat body 3 to the outer side of the stress base plate 1.
[0018] In this embodiment, the lifting mechanism 6 includes a guide rail 2, a convex seat 3, an internally threaded tube 4, a fastener 10, a slider 12, and a bearing seat 15. The bottom end of the guide rail 2 is connected to the top end of the stress substrate 1. The top end of the convex seat 3 is welded with internally threaded tubes 4 at equal intervals. The internally threaded tubes 4 are connected to the inside of the internally threaded tubes 4. The top end of the slider 12 is connected to the bottom end of the convex seat 3. The bottom end of the stress substrate 1 is connected to the bearing seat 15. The bottom end of the convex seat 3 is fixedly provided with sliders 12, which are slidably connected to the outer side of the guide rail 2 symmetrically arranged on the stress substrate 1. The top end of the convex seat 3 is provided with a plurality of internally threaded tubes 4 at equal intervals. The internally threaded tubes 4 are rigidly connected to the outer side of the fasteners 10 through threaded engagement.
[0019] Specifically: After passing through the docking hole from the top of the seat frame, it is screwed into the internal threaded tube 4 through thread engagement until the head of the fastener 10 presses against the seat frame, thus achieving a rigid connection between the seat frame and the convex seat 3. The spacing of the convex seat 3 can be readjusted by loosening the bolts in the fastening hole 11 without the need for complicated tools. The threaded connection between the internal threaded tube 4 and the fastener 10 supports one-handed operation, which is convenient for later maintenance or seat replacement.
[0020] In this embodiment, the adjusting mechanism 9 includes a spring post 7, a guide rod 8, a fastening hole 11, an inner guide hole 13, and a flexible rubber pad 14. The spring post 7 is disposed in the middle of the guide rod 8. The fastening holes 11 are symmetrically disposed on the outer side of the convex seat 3. The bottom end of the convex seat 3 is fitted with the flexible rubber pad 14. Two sets of convex seats 3 are fitted on both the left and right sides of the spring post 7. The inner guide holes 13 are symmetrically opened through the inside of the convex seat 3. The inner guide holes 13 are symmetrically opened through the two sides of the convex seat 3 and are directly connected to the left and right sides of the guide rod 8. The bottom end of the convex seat 3 is fixedly provided with the flexible rubber pad 14, and the flexible rubber pad 14 is flexibly fitted with the top end of the stress substrate 1.
[0021] Specifically: the guide rod 8 of the adjusting mechanism 9 is combined with the spring column 7 to realize the dynamic adjustment of the distance between the two sets of convex seat bodies 3. The internal thread tube 4 of the lifting mechanism 6 and the fastener 10 provide a high rigidity connection through the thread preload, ensuring that the seat frame does not sink or shift under vertical loads such as passenger weight, while restricting the degree of rotational freedom.
[0022] In practical applications, this type of car seat base frame with anti-slip limiting protrusions includes the following functions: The operator installs the bottom bearing seat 15 of the stress base plate 1 inside the car. The stress base plate 1 serves as the load-bearing base of the entire frame. The stress base plate 1 forms a support frame through the guide rail installed at its top. The guide rail 2 provides a straight guide path for the lateral sliding of the convex seat 3. The bearing seat 15 helps to distribute the vertical load. The bottom end of the convex seat 3 is fixedly provided with a slider bar 12. The slider bar 12 slides with the outer side of the guide rail 2, allowing the convex seat 3 to slide freely along the axial direction of the guide rail 2, thus achieving preliminary position adjustment. The lifting mechanism 6 is aligned with the docking hole at the bottom of the seat frame via the internal threaded tube 4 at the top of the guide rail 2 (not shown in the figure). The internal threaded tube 4 is welded at equal intervals to the top of the convex seat 3 or fixed by bolts. After the fastener 10 passes through the docking hole from the top of the seat frame, it is screwed into the internal threaded tube 4 through thread engagement until the head of the fastener 10 presses against the seat frame, thus achieving a rigid connection between the seat frame and the convex seat 3. The operator works in coordination with the guide rod 8 and the spring column 7: the guide rod 8 horizontally passes through the symmetrically opened inner guide holes 13 inside the two sets of convex seat bodies 3. The inner guide holes 13 are directly connected to the guide rod 8, providing precise guidance for the lateral movement of the convex seat bodies 3; the spring column 7 is located in the middle of the guide rod 8, and balances the change in the distance between the two sets of convex seat bodies 3 through elastic deformation compression or stretching.
[0023] When the car seat frame is wide, the convex seat 3 is pulled outward, the spring column 7 is stretched, and the inner guide hole 13 slides along the guide rod 8 until the distance between the two sets of convex seat 3 matches the width of the seat frame; otherwise, the spring column 7 is compressed inward. After adjustment, fastening bolts are inserted through the fastening holes 11 symmetrically set on the outside of the convex seat 3 to temporarily lock the convex seat 3 and the stress base plate 1 or guide rail 2 to fix the current distance.
[0024] The flexible rubber pad 14 is fixed to the bottom of the convex seat 3 and is directly and flexibly attached to the top of the stress substrate 1. The limiting surfaces on both sides of the spring column 7 press the two sets of convex seats 3 toward the center of the guide rod 8 through the elastic pressure of the spring column 7, forming a self-locking anti-slip limit. Even if the spring column 7 is not completely locked, the convex seat 3 will maintain its current position due to the frictional resistance of the flexible rubber pad 14, preventing accidental sliding.
[0025] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
