Description

Technical Field

[0001] This utility model relates to the field of automotive seat frame welding technology, specifically to an automotive seat frame welding tilting table structure. Background Technology

[0002] The car seat frame provides support and stability for the seat. It is usually made of metal materials (such as steel or aluminum alloy) and has sufficient strength and rigidity to support the weight of the occupant and provide a comfortable seating experience.

[0003] A search revealed a welding tilting table structure for an automotive seat frame, with publication number CN221087753U. This application states that after the tilting table fixes the automotive seat frame, the limiting components can keep both sides of the automotive seat frame slightly tilted, thus facilitating the welding of the automotive seat frame's components.

[0004] However, in practical application, it has been found that the existing structure still has certain limitations: during the flipping operation, the limiting rod and the first limiting cylinder need to be precisely aligned before fixation can be achieved. This alignment process usually requires operators to repeatedly adjust the position of the flipping table, which not only increases the complexity of operation but also reduces the overall efficiency of welding operations. Especially in continuous, batch production environments, frequent alignment operations can lead to extended production cycles, affecting the continuity of the manufacturing process and production efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a welding and flipping table structure for automotive seat frames to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a welding and flipping table structure for an automobile seat frame, including a fixed base, a rotating shaft installed on the inner side of the fixed base, the rotating shaft passing through the fixed base and being rotatably connected to the fixed base, a platform fixed on the outer surface of the rotating shaft, and a flipping component and a stabilizing component installed on the outer surface of the fixed base, the flipping component facilitating the flipping operation of the platform, and the stabilizing component locking the platform.

[0007] The flipping component includes:

[0008] A circular block, which is fixed to the outer surface of the rotating shaft for synchronous rotation with the rotating shaft;

[0009] A fixed frame is fixed to the outer surface of the fixed base to stabilize the internal mechanisms.

[0010] A limiting block is installed inside a fixed frame to cooperate with a limiting groove for limiting and stabilizing.

[0011] Preferably, the circular block is fixed to the outer surface of the rotating shaft, and a limiting groove is formed on the outer surface of the circular block. A fixing frame is fixed to the outer surface of the fixing seat. A rack is slidably connected to the inner wall of the fixing frame, a gear ring is rotatably connected to the inner wall of the fixing frame, and a gear is rotatably connected to the inner wall of the fixing frame. The circular block rotates synchronously with the rotating shaft, and the automatic locking and guidance during angle adjustment is achieved by the cooperation of the limiting groove and the subsequent limiting block. The fixing frame serves as the mounting base for each transmission component, and the rack, gear ring, and gear inside it form a linkage mechanism that can drive the limiting components to move automatically when the rotating shaft rotates.

[0012] Preferably, the rack meshes with the gear, the gear meshes with the gear ring, a spiral spring is fixed to the outer surface of the gear ring, and the end of the spiral spring away from the gear ring is fixed to the inner wall of the fixed frame. A limit block is fixed to the outer surface of the rack, the limit block penetrates the fixed frame, and the cross-section of the limit block is triangular. The meshing relationship between the rack, gear, and gear ring ensures that multiple racks can move radially synchronously. The spiral spring stores energy when the gear ring rotates and releases energy after the limit groove is aligned, driving the limit block to automatically engage with the limit groove and achieve automatic locking. The triangular cross-section of the limit block facilitates contact with the inclined surface of the limit groove and retraction during rotation, completing the yielding and resetting action.

[0013] Preferably, a movable rod is fixed to the outer surface of the rack, and the end of the movable rod away from the rack passes through the fixed frame. A rotating ring is rotatably connected to the outer surface of the fixed frame. A notch is provided on the inner side of the rotating ring. The movable rod moves synchronously with the rack and passes through the fixed frame to engage with the notch of the rotating ring. The notch allows the movable rod to pass through when adjusting the angle, and blocks the movable rod after the rotating ring rotates, thereby locking the rack position and preventing the rotating shaft from rotating accidentally.

[0014] Preferably, the stabilizing component includes a fixed cylinder fixed to the outer surface of the rotating ring. A stabilizing column is slidably connected to the inner wall of the fixed cylinder. The end of the stabilizing column away from the fixed cylinder passes through the rotating ring. A spring is fixed to the outer surface of the stabilizing column. The end of the spring away from the stabilizing column is fixed to the inner wall of the fixed cylinder. A bolt abuts against the outer surface of the stabilizing column. The end of the bolt away from the stabilizing column passes through the fixed cylinder and is threadedly connected to the fixed cylinder. A stabilizing groove is formed on the outer surface of the fixed frame. The end of the stabilizing column away from the spring is arc-shaped. Eight sets of stabilizing grooves are arranged in a circular array around the center of the fixed frame. The stabilizing column can automatically engage with the stabilizing groove under the action of the spring, realizing rapid positioning of the rotating ring. The bolt can tighten the stabilizing column to prevent it from accidentally retracting, enhancing locking reliability. The eight sets of stabilizing grooves correspond to multiple commonly used angle positions, improving adjustment flexibility.

[0015] Preferably, a base block is fixed to the inner bottom of the frame, and a slide rod is installed on the outer surface of the frame. The slide rod passes through the frame and is slidably connected to the frame. A side block is fixed to the end of the slide rod away from the frame. A screw is rotatably connected to the outer surface of the side block. The end of the screw away from the side block passes through the frame and is threadedly connected to the frame. A knob is fixed to the end of the screw away from the side block. The base block and the side block cooperate to form a clamping area for fixing the frame. The slide rod guides the side block to move linearly to ensure stable clamping. The screw drives the side block to move forward and backward through threaded transmission to achieve rapid clamping and releasing. The knob provides a manual operation interface for users to adjust the clamping force.

[0016] Compared with the prior art, this utility model provides a welding and flipping table structure for automotive seat frames, which has the following advantages:

[0017] 1. This automotive seat frame welding flip-up table structure, through the set flip-up components, when the rotating platform adjusts the flip angle, the limiting block is restricted by the limiting groove and retracts into the fixed frame, driving the rack to drive the gear and gear ring to rotate, so that all racks and limiting blocks move radially synchronously, while the spiral spring coils up; after the limiting block is aligned with the limiting groove, the spiral spring automatically releases, pushing each mechanism to reset and making the limiting block lock into the groove. During the process, the rack drives the moving rod to slide within the notch of the rotating ring, without affecting the adjustment. When the adjustment is completed, pulling the fixed cylinder drives the rotating ring to rotate, causing the notch and the moving rod to misalign, and the inner wall of the rotating ring then presses against the moving rod, locking the rack and the round block. No manual fine operation is required, significantly improving efficiency.

[0018] 2. The automotive seat frame features a welded tilting platform structure. Through a stabilizing component, when the rotating ring rotates, the stabilizing column is compressed into the fixed cylinder by the inner wall of the stabilizing groove, compressing the spring. When the stabilizing column aligns with the groove, the spring automatically releases, pushing the stabilizing column into the groove to prevent the rotating ring from rotating on its own. To further prevent accidental activation, a rotatable bolt can be rotated to press its end against the outer surface of the stabilizing column, restricting its movement and ensuring reliable locking.

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: a welding and flipping table structure for an automobile seat frame, including a fixed base 1, a rotating shaft 3 installed on the inner side of the fixed base 1, the rotating shaft 3 passing through the fixed base 1 and rotatably connected to the fixed base 1, a platform 2 fixed on the outer surface of the rotating shaft 3, and a flipping component 8 and a stabilizing component 9 installed on the outer surface of the fixed base 1. The flipping component 8 is used to facilitate the flipping operation of the platform 2, and the stabilizing component 9 is used for locking. The flipping component 8 includes: a round block 80, a fixed frame 81, a rack 82, a gear 83, a gear ring 84, a spiral spring 85, a limiting block 86, a limiting groove 87, a rotating ring 88, a moving rod 89, and a notch 800.

[0026] A circular block 80 is fixed to the outer surface of the rotating shaft 3, a fixed frame 81 is fixed to the outer surface of the fixed base 1, a limiting block 86 is installed inside the fixed frame 81, a limiting groove 87 is formed on the outer surface of the circular block 80, a fixed frame 81 is fixed to the outer surface of the fixed base 1, a rack 82 is slidably connected to the inner wall of the fixed frame 81, a gear ring 84 is rotatably connected to the inner wall of the fixed frame 81, and a gear 83 is rotatably connected to the inner wall of the fixed frame 81. The rack 82 meshes with the gear 83, the gear 83 meshes with the gear ring 84, and a limiting block 86 is fixed to the outer surface of the gear ring 84. A spiral spring 85 is fixed to the inner wall of a fixed frame 81 at one end away from the toothed ring 84. A limit block 86 is fixed to the outer surface of a rack 82, and the limit block 86 passes through the fixed frame 81. A moving rod 89 is fixed to the outer surface of the rack 82, and the end of the moving rod 89 away from the rack 82 passes through the fixed frame 81. The cross-section of the limit block 86 is triangular. A rotating ring 88 is rotatably connected to the outer surface of the fixed frame 81. A notch 800 is opened on the inner side of the rotating ring 88. When it is necessary to adjust the flipping angle, the rotating platform 2 can drive the rotating shaft 3 and the round block 80 to rotate synchronously. At this time, the limiting block 86, constrained by the inner wall of the limiting groove 87, retracts inward into the fixing frame 81, driving the rack 82 to move. This causes the gear 83 to drive the gear ring 84 to rotate, thereby driving all racks 82 and limiting blocks 86 to move radially synchronously. Simultaneously, the spiral spring 85 winds up. When the limiting block 86 is aligned with the limiting groove 87, the spiral spring 85 releases, and all mechanisms automatically reset, causing the limiting block 86 to engage in the limiting groove 87, achieving automatic alignment without manual operation. During the process, the rack 82 drives the moving rod 89 to move within the notch 800 of the rotating ring 88, without affecting normal adjustment. After the angle adjustment is completed, the rotatable bolt 93 can be rotated so that its end is disengaged from the stabilizing column 91. Then, the fixed cylinder 90 is pulled to drive the rotating ring 88 to rotate, so that the notch 800 is misaligned with the moving rod 89. At this time, the inner wall of the rotating ring 88 will abut against the moving rod 89, thereby restricting the rotation of the rack 82 and the round block 80, achieving reliable locking, which is convenient for subsequent processing. The whole process does not require precise manual adjustment, which effectively improves the efficiency of use.

[0027] The stabilizing assembly 9 includes a fixed cylinder 90, which is fixed to the outer surface of the rotating ring 88. A stabilizing column 91 is slidably connected to the inner wall of the fixed cylinder 90. The end of the stabilizing column 91 away from the fixed cylinder 90 passes through the rotating ring 88. A spring 92 is fixed to the outer surface of the stabilizing column 91. The end of the spring 92 away from the stabilizing column 91 is fixed to the inner wall of the fixed cylinder 90. A bolt 93 abuts against the outer surface of the stabilizing column 91. The end of the bolt 93 away from the stabilizing column 91 passes through the fixed cylinder 90, and the bolt 93 is threadedly connected to the fixed cylinder 90 for fixation. The outer surface of frame 81 is provided with stabilizing grooves 94. The end of stabilizing post 91 away from spring 92 is arc-shaped. There are eight sets of stabilizing grooves 94, arranged in a circular array around the center of fixed frame 81. When rotating ring 88, stabilizing post 91 is squeezed by the inner wall of stabilizing groove 94 and retracts inward into fixed cylinder 90, compressing spring 92. When stabilizing post 91 is aligned with stabilizing groove 94, spring 92 is released, pushing stabilizing post 91 to automatically engage in stabilizing groove 94, thereby preventing rotating ring 88 from rotating on its own. To further prevent accidental contact from affecting stability, rotatable bolt 93 can be rotated so that its end abuts against the outer surface of stabilizing post 91, restricting movement of stabilizing post 91 and ensuring reliable locking.

[0028] A base block 4 is fixed to the bottom inner side of the frame 2. A slide rod 5 is installed on the outer surface of the frame 2, passing through the frame 2 and slidably connected to it. A side block 6 is fixed to the end of the slide rod 5 away from the frame 2. A screw 10 is rotatably connected to the outer surface of the side block 6, passing through the frame 2 and threadedly connected to it. A knob 7 is fixed to the end of the screw 10 away from the side block 6. In use, the frame is placed inside the base block 4, and rotating the knob 7 rotates the screw 10, thereby adjusting the position of the side block 6 to ensure a stable fit with the frame and reliable fixation. The slide rod 5 acts as a guide and support during adjustment, ensuring smooth movement of the side block 6.

[0029] In use, place the frame inside the base block 4. Then, turn the knob 7 to rotate the screw 10, which will adjust the stability of the side block 6 and the frame, making it easier to fix the frame. The slide rod 5 facilitates the stable movement of the side block 6. When it is necessary to flip and adjust its angle, flip the platform 2 to adjust the angle. When the platform 2 rotates, the rotating shaft 3 rotates synchronously, driving the round block 80 to rotate. At this time, the outer surface of the limiting block 86 abuts against the inner wall of the limiting groove 87, and the limiting block 86 moves into the fixed frame 81. Simultaneously, the rack 82 moves, causing the gear 83 to rotate, which in turn drives the gear ring 84 to rotate. This allows the racks 82 and the limiting blocks 86 to move radially synchronously. At this time, the spiral spring 85 rewinds. When the position of the limiting block 86 is parallel to the limiting groove 87, the spiral spring 85 releases, which drives the mechanism to reset, allowing the limiting block 86 to enter the limiting groove 87 without manual alignment. Meanwhile, as the rack 82 moves, it drives the moving rod 89 to move within the notch 800, without affecting normal adjustment. Once adjusted, the flipping mechanism... When rotating, the bolt 93 is rotated so that its end disengages from the stabilizing column 91. At this point, the fixed cylinder 90 can be pulled normally to rotate the rotating ring 88, causing the notch 800 and the moving rod 89 to intersect. The inner side of the rotating ring 88 then contacts the outer surface of the moving rod 89, thus limiting the movement of the moving rod 89 and the rack 82. The circular block 80 and the rotating shaft 3 can no longer rotate, thus achieving the limiting function, facilitating subsequent processing, eliminating the need for precise manual control, and improving efficiency. Simultaneously, as the rotating ring 88 rotates, the stabilizing column 91... The outer surface of 1 contacts the inner wall of the stabilizing groove 94. At this time, the stabilizing column 91 moves into the fixed cylinder 90, and the spring 92 is compressed. When the position of the stabilizing column 91 is parallel to the stabilizing groove 94, the spring 92 is released, which can drive the stabilizing column 91 into the stabilizing groove 94, thus preventing the rotating ring 88 from rotating. At the same time, in order to avoid accidental contact affecting stability, the bolt 93 is rotated so that its end contacts the outer surface of the stabilizing column 91, which can limit the stabilizing column 91. At this time, the stabilizing column 91 cannot continue to move, thus preventing accidental contact from affecting stability.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
