Description

Technical Field

[0001] This utility model relates to the field of seat back panel production machinery technology, specifically to a seat back panel inspection tool. Background Technology

[0002] The seat back panel is installed behind the car seat to protect the internal structure and provide support, directly affecting the strength and rigidity of the seat assembly. The most common way to connect the back panel to the seat is through a snap-on fastening system. The back panel has hook grooves, and the seat frame has fixing rods; the two are fastened by pressing or rotating. This fastening structure improves installation efficiency and is relatively simple to operate. However, to improve passenger comfort or provide more legroom for rear passengers, car back panels are often designed with a curved structure. This results in internal stress, leading to poor fit between the back panel and the seat, especially in plant fiber low-pressure molded seat back panels, where gaps and snap-on misalignment are common. Manual inspection of seat back panels is inefficient and inconsistent.

[0003] Therefore, it is necessary to design a seat back panel inspection tool to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a seat back panel inspection tool for detecting the fit between the seat back panel and the seat, and to quickly determine the structural quality of the back panel.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A seat back panel inspection tool includes a mounting frame, a mounting plate on the mounting frame, a plurality of connecting frames on one side of the mounting plate, a fixing rod and a buckle adapted to the seat back panel on the connecting frames, a seat frame outer peripheral part and a seat angle adjustment part on the same side of the mounting plate and the connecting frames, and a card seat on the mounting plate, wherein a needle gauge handle is detachably installed in the card seat.

[0007] Furthermore, the buckle is hinged to the connecting frame, and a limit block is fixedly installed on the side of the connecting frame. The limit block is set on the path of the buckle hinge, and a first spring is set between the limit block and the buckle. The two ends of the first spring abut against the buckle and the limit block respectively.

[0008] Furthermore, the lower part of the mounting plate is also equipped with a plug-in connection structure, with the fixing rod, buckle, and plug-in connection structure arranged sequentially from top to bottom.

[0009] Furthermore, the plug-in connection structure includes: a connecting cylinder for fixed connection with the back plate, a movable rod coaxially arranged on the connecting cylinder, the movable rod passing through an L-shaped piece fixedly arranged on the connecting frame, a shoulder provided at the end of the movable rod away from the connecting cylinder, a second spring sleeved on the movable rod, one end of the second spring abutting against the shoulder of the movable rod, and the other end of the second spring abutting against the L-shaped piece.

[0010] Furthermore, an adjusting rod is fixedly connected to the connecting frame and the buckle, and the mounting plate is equipped with an inspection window adapted to the plug-in connection structure and the adjusting rod.

[0011] Furthermore, the needle gauge handle is connected to the mounting plate via a spring wire.

[0012] To facilitate the assembly and movement of the inspection fixture, increase its overall stability, and reduce the number of assembly parts required for its production, the technical solution provided by this utility model further includes: side plates are provided on both sides of the mounting plate at a certain angle to the mounting plate; angle irons that adapt to the side plates extend upward from the outer periphery of the mounting frame; the side plates are fixed to the angle irons by bolts; the side plates and the mounting frame are detachably connected by bolts; and casters are connected to the bottom of the mounting frame.

[0013] Furthermore, the mounting plate and the side plate are vertically eccentrically offset, so that after the seat back panel is fixed on the mounting plate, the center of gravity of the two is located at the center of the inspection fixture.

[0014] Furthermore, handles are provided on both sides of the mounting plate.

[0015] Furthermore, the mounting bracket has a base plate at the bottom, which is used to place inspection tools, such as needle gauge handles of different specifications, unlocking terminals for seat back panel locks, and boss buttons corresponding to the specifications of seat back panels.

[0016] The advantages and beneficial effects of this utility model are as follows:

[0017] 1. Fix the seat back panel to this inspection tool using fixing rods and buckles. Then, use the needle gauge handle to confirm the standard of the gap between the back panel and the outer periphery of the seat frame and the seat angle adjustment part. This can quickly determine whether the fit between the seat back panel and the seat meets the standard.

[0018] 2. The fixing rod, buckle, and plug-in connection structure are set from top to bottom. During installation, first connect the back panel slot to the fixing rod, then the buckle and plug-in structure. This ensures that the fixture and the back panel are firmly connected. The seat back panel can be pulled out diagonally from the fixture by unlocking the plug-in structure through the inspection window, making it quicker to replace the back panel.

[0019] 3. The casters, mounting plate, side plates, and base plate of the inspection fixture increase its overall stability, making it less prone to tipping over during operation and facilitating operator adjustment of its position. The side plates and mounting bracket are detachably connected by bolts, allowing them to be installed separately during production and then assembled later, improving efficiency.

Detailed Implementation

[0028] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0029] Example

[0030] A seat back panel inspection fixture includes a mounting frame 1, on which a mounting plate 2 is vertically mounted. Multiple connecting brackets 3 are fixed to one side of the mounting plate 2. From top to bottom, the connecting brackets 3 are respectively equipped with a fixing rod 4, a buckle 5, and a pluggable connection structure 6 adapted to the seat back panel. On the same side of the mounting plate 2 and the connecting brackets 3, a seat frame outer perimeter replica 7 and a seat angle adjustment replica 8 are also provided. The mounting plate 2 is provided with a retaining seat 9, within which a gauge handle 10 is detachably mounted. The gauge handle 10 is connected to the mounting plate 2 via a spring wire.

[0031] The buckle 5 is hinged to the connecting frame 3. A limiting block 11 adapted to the buckle 5 is fixedly provided on the side of the connecting frame 3. The limiting block 11 is installed on the movable path of the buckle 5. A first spring 12 is provided between the limiting block 11 and the buckle 5. The two ends of the first spring 12 abut against the buckle 5 and the limiting block 11 respectively. An adjusting rod 18 is fixedly connected to the buckle 5 through the connecting frame 3.

[0032] The plug-in connection structure 6 includes: a connecting cylinder 13 for fixed connection with the back plate; a movable rod 14 coaxial with the connecting cylinder 13 and fixed to one end thereto; the movable rod 14 passes through the L-shaped piece 15 on the connecting frame 3 and extends out to the shoulder 16; a second spring 17 is sleeved on the movable rod 14; the two ends of the second spring 17 abut against the shoulder 16 and the L-shaped piece 15 respectively; and the mounting plate 2 is provided with an inspection window 19 adapted to the plug-in connection structure 6 and the adjusting rod.

[0033] To facilitate the assembly and movement of the fixture, increase its overall stability, and reduce the number of assembly parts required for its production, the technical solution provided in this embodiment further includes: side plates 20 are fixed perpendicularly to both sides of the mounting plate 2, the side plates 20 are flush with the bottom surface of the mounting plate 2, angle irons 21 adapted to the side plates 20 are welded upwards on the outer periphery of the mounting frame 1, the side plates 20 are fixed to the angle irons 21 by bolts, two directional casters 22 are installed on one side of the bottom of the mounting frame 1, and two universal casters 23 with brakes are installed on the other side.

[0034] The mounting plate 2 and the side plate 20 are slightly offset vertically along their central axes, with the mounting plate 2 positioned at 1 / 3 of the length of the bottom surface of the side plate 20. The side containing the connecting bracket 3 is positioned at 2 / 3 of the length of the side plate 20. This ensures that after the seat back panel is fixed to the mounting plate 2, the center of gravity of both is as close as possible to the axis of the inspection fixture, i.e., the geometric center of the inspection fixture, preventing the equipment from tipping over due to uneven weight distribution. Handles 24 are provided on both sides of the mounting plate 2. A base plate 25 is provided at the bottom of the mounting bracket 1. The base plate 25 is used to place auxiliary tools for the inspection fixture, such as needle gauge handles 10 of different specifications, unlocking terminals for the seat back panel lock, and boss buttons corresponding to the specifications of the seat back panel.

[0035] Working principle:

[0036] First, the seat back panel is placed on the inspection fixture and then secured to the mounting plate 2 via the fixing rod 4, buckle 5, and plug-in connection structure 6. These fixing devices simulate the installation method of the seat back panel in an actual vehicle, ensuring the back panel remains stable during inspection. The seat angle adjustment mockup 8 simulates the actual usage conditions the seat back panel may face. Simultaneously, tools such as the pin gauge handle 10 can be used to check whether specific parts or details of the back panel meet design standards. For example, the pin gauge handle 10, with end diameters of 4mm and 6mm respectively, is slid along the gap between the mockup and the seat back panel; ideally, the 6mm end should not get stuck in the gap, while the 4mm end should. The inspection fixture is designed with stability and safety in mind. For example, side plates 20 and angle irons 21 are used to increase overall stability, and directional casters 22 and braked swivel casters 23 facilitate movement and fixation of the inspection fixture. Furthermore, the handle 24 allows operators to move the inspection fixture or move the mounting plate independently after disconnecting the angle iron 21. The rapid assembly of this embodiment is reflected in the top-to-bottom arrangement of a fixing rod, a buckle, and a plug-in connection structure. During assembly, the fixing rod is first inserted into the slot of the back panel from top to bottom. Rotating the seat back panel around the slot will fix the buckle. Specifically, the buckle is locked to the seat back panel buckle by an inclined surface. The first spring 12 pulls the hinged inspection tool buckle tight through tension. The bottom is connected by a plug-in connection to ensure accurate positioning of the seat back panel. Understandably, since the seat back panel also has a certain amount of curvature, the buckle 5 also extends an adjustment rod for manual adjustment of each buckle 5. After locking, gently push the seat back panel to ensure stable locking. The base plate 25 is used to store inspection tool auxiliary tools, such as needle gauge handles 10 of different specifications, unlocking terminals of the seat back panel lock, etc., for easy access by operators during the inspection process.

[0037] The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
