Description

Technical Field

[0001] This utility model relates to the field of automotive parts assembly and production, and in particular to an auxiliary installation tool for automotive seat frames. Background Technology

[0002] During the installation of car seats, it is usually necessary to first assemble the car seat frame with the seat rail. The commonly used assembly process is to set spring pins on the seat rail and set pin holes on the seat frame. The seat frame is pushed by hand to slide along the seat rail. After the seat frame slides into place, the spring pin pops out into the pin hole. The assembly of the seat frame and the seat rail is completed through the cooperation between the spring pin and the pin hole.

[0003] Because the seat frame needs to be assembled with the seat, multiple mounting holes are usually set in the coaxial direction of the seat frame pin holes. This causes the spring pins on the seat rails to enter the mounting holes of the seat frame during the sliding assembly process. The operator needs to use a push rod to compress the spring pins into the seat rails while manually pushing the seat frame to continue sliding along the rails. As the seat rails move, the spring pins will enter other mounting holes in the seat frame, and the operator needs to repeat this operation until the seat rail spring pins and seat frame pin holes are properly engaged. This process is cumbersome and severely restricts the efficiency of seat frame installation. Utility Model Content

[0004] This utility model aims to solve the above problems and provides an auxiliary installation tool for automobile seat frames, the technical solution of which is as follows:

[0005] An auxiliary installation tool for an automotive seat frame includes a frame and six filler pins. The frame includes longitudinal beams and transverse beams. The middle of the transverse beams is connected to one end of the longitudinal beams, forming a T-shaped structure symmetrical about the longitudinal beams in the same plane. The filler pins are perpendicular to the plane of the T-shaped structure. The filler pins are fixedly connected to both ends of the transverse beams in two groups, with three filler pins in each group. The filler pins are arranged in parallel and all extend in the same direction as the mounting holes on the seat frame. The positions of the filler pins correspond to the positions of the mounting holes on the seat frame, and the length of the filler pins is the same as the depth of the mounting holes.

[0006] Based on the above scheme, a rear limiting block is also included. The rear limiting block is connected to the end of the frame longitudinal beam away from the frame transverse beam. The rear limiting block is provided with an open positioning groove, and the opening faces the side of the filling pin.

[0007] Based on the above scheme, elongated through holes are respectively provided at the connection positions of the rear limiting block and the frame longitudinal beam, and the length direction of the elongated through holes is consistent with the length direction of the frame longitudinal beam.

[0008] Preferably, it also includes a front limiting block, a limiting bolt, and a locking nut. There are multiple front limiting blocks, which are fixedly installed on the frame crossbeam and symmetrically arranged about the frame longitudinal beam. The limiting bolt and the locking nut are threaded through the front limiting block, and the through direction is the same as that of the frame longitudinal beam.

[0009] Preferably, it also includes a handle, which is fixedly installed on the side of the frame longitudinal beam away from the filler pin, and its length direction is consistent with the length direction of the frame longitudinal beam.

[0010] Preferably, it also includes a handle and a handle mounting base. The handle includes a hand-held part and a connecting part. The hand-held part is U-shaped with the U-shaped opening facing the direction of the frame beam. The connecting part is fixedly connected to the ends of the two free ends of the hand-held part and is fixedly installed on the frame beam by the handle mounting base.

[0011] Based on the above scheme, the hand-held part gradually tilts away from the filler pin along the direction away from the frame beam.

[0012] Preferably, the handle fixing seat is a plate-like structure with a raised center, and there are multiple such structures. Two adjacent handle fixing seats form a group, which are respectively connected to the two connecting parts of the same handle. They are fixed at intervals to the end face of the frame beam opposite the filling pin. The handle fixing seat has a raised center and forms a cavity with the frame beam through which the connecting parts can pass.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This tool is equipped with a filler pin corresponding to the mounting hole position of the seat frame. When the tool is used with the seat frame, the filler pin can be inserted into the mounting hole of the seat frame, and the bottom surface of the filler pin is flush with the bottom surface of other parts of the seat frame. This ensures that the seat slide rail spring pin will not pop out and enter the seat frame mounting hole during the axial sliding assembly of the seat frame. This avoids the repetitive pressing operation caused by the seat slide rail spring pin entering the seat frame mounting hole, thus improving work efficiency.

[0015] 2. By setting up quick positioning and auxiliary adjustment mechanisms such as rear limit block, front limit block, limit bolt and locking nut, the filling pin and seat frame mounting hole can be quickly matched, improving work efficiency.

[0016] 3. By setting a handle on the frame beam and setting a certain tilt angle between the handle and the frame beam, it is convenient for workers to push the tool and the seat frame to slide on the seat rail at the same time, which facilitates operation. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0024] In the description of this utility model, it should be understood that the terms "center," "length," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," and "inner," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0025] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an auxiliary installation tool for a car seat frame includes a frame and six filler pins 17. The frame includes a frame longitudinal beam 11 and a frame cross beam 12. The middle of the frame cross beam 12 is connected to one end of the frame longitudinal beam 11, forming a T-shaped structure symmetrical about the frame longitudinal beam 11 in the same plane. The filler pins 17 are perpendicular to the plane of the T-shaped structure. The filler pins 17 are fixedly connected to both ends of the frame cross beam 12 in two groups, with three filler pins in each group. The multiple filler pins 17 are arranged in parallel and are all aligned with the extension direction of the mounting holes 21 on the seat frame 2. The positions of the filler pins 17 are relative to the seat frame. The mounting hole 21 on the seat frame 2 is positioned accordingly, and the length of the filling pin 17 is the same as the depth of the mounting hole 21. This ensures that when the tool is used with the seat frame 2, the filling pin 17 can be inserted into the mounting hole 21 on the seat frame 2, and the bottom surface of the filling pin 17 is flush with the bottom surface of other parts of the seat frame 2. This ensures that during the axial sliding assembly of the seat frame 2 on the seat slide rail 3, the spring pin 31 on the seat slide rail 3 will not pop out and enter the mounting hole 21 on the seat frame 2. This avoids repetitive adjustment operations caused by the spring pin 31 on the seat slide rail 3 entering the mounting hole 21 on the seat frame, thus improving work efficiency.

[0027] Preferably, the present invention further includes a rear limiting block 13, which is connected to the end of the frame longitudinal beam 11 away from the frame transverse beam 12. The rear limiting block 13 is provided with an open positioning groove, with the opening facing the filling pin 17, so that the positioning groove can be engaged with the front transverse tube 22 of the seat frame 2. Elongated through holes are provided at the connection points between the rear limiting block 13 and the frame longitudinal beam 11, and the length direction of the elongated through holes is consistent with the length direction of the frame longitudinal beam 11. Bolts or connecting parts with the same function are sequentially passed through the elongated through holes on the rear limiting block 13 and the frame longitudinal beam 11, and the bolts are tightened with nuts to achieve relative fixation between the rear limiting block 13 and the frame longitudinal beam 11. By adjusting the position of the bolts in the two elongated through holes, the relative position of the positioning groove and the frame longitudinal beam 11 can be adjusted, thereby adapting to seat frames 2 of different sizes or models. During installation, the front transverse tube 22 of the seat frame 2 is engaged in the positioning groove to complete the positioning of the seat frame 2 with one side of the installation tool.

[0028] Preferably, the present invention further includes a front limiting block 14, a limiting bolt 15, and a locking nut 16. Multiple front limiting blocks 14 are fixedly installed on the frame crossbeam 12 and symmetrically arranged about the frame longitudinal beam 11. The limiting bolt 15 and the locking nut 16 are threaded through the front limiting block 14, with the through direction being the same as the frame longitudinal beam 11. The limiting bolt 15 abuts against a positioning surface in the seat frame 2, achieving pre-positioning of the installation tool and facilitating the quick insertion of the filler pin 17 into the mounting hole 21. By adjusting the unscrewing dimension of the limiting bolt 15, the relative mating position between the installation tool and the seat frame 2 is adjusted, thereby adapting the installation tool to seat frames 2 of different sizes or models.

[0029] Preferably, the present invention further includes a handle 18, which is fixedly installed on the side of the frame longitudinal beam 11 away from the filler pin 17, and its length direction is consistent with the length direction of the frame longitudinal beam 11. During the process of assembling the present invention with the seat frame 2 and removing it from the seat frame 2 after use, the operator can easily perform the above operations by holding the handle 18, saving the operator's physical strength.

[0030] Preferably, the present invention further includes a handle 19 and a handle fixing seat 110. The handle 19 includes a hand-held portion 192 and a connecting portion 191. The hand-held portion 192 is U-shaped, with the U-shaped opening facing the frame beam 12. The connecting portion 191 is fixedly connected to the ends of the two free ends of the hand-held portion 192 and is fixedly mounted on the frame beam 12 by the handle fixing seat 110. The hand-held portion 192 gradually tilts away from the frame beam 12 and away from the filling pin 17, thereby forming an upward tilt angle, which makes it easier for the operator to push in the seat frame 2 during installation. The handle fixing seat 110 is a plate-like structure with a raised center. There are multiple such seats. Two adjacent handle fixing seats 110 form a group, which are respectively connected to the two connecting portions 191 of the same handle 19. They are fixed at intervals to the end face of the frame beam 12 opposite to the filling pin 17. The handle fixing seat 110 has a raised center and forms a cavity with the frame beam 12 through which the connecting portion 191 can pass.

[0031] Figure 5 This invention demonstrates the process of quickly assembling a seat frame 2 along a seat slide rail 3 to a predetermined position. First, the invention is fitted with the seat frame 2, i.e., the filler pin 17 is inserted into the mounting hole 21 of the seat frame 2. At this point, the bottom surface of the filler pin 17 is flush with the bottom surface of other parts of the seat frame 2. Then, the operator simultaneously holds the handle 192 and the front cross tube 22 and pushes the invention and the seat frame 2 along the seat slide rail 3. During this process, because the mounting hole 21 on the seat frame 2 is filled by the filler pin 17, the spring pin 31 in the seat slide rail 3 remains compressed and cannot pop out. This ensures that the seat frame 2 will not be obstructed from pushing along the seat slide rail 3 due to the spring pin 31 entering the mounting hole 21, thus quickly pushing the seat frame 2 to the predetermined assembly position. Finally, when the seat frame 2 reaches the predetermined assembly position, the spring pin 31 pops out from the seat slide rail 3 and enters the spring pin hole in the seat frame 2, thus fixing the seat frame 2 in the predetermined assembly position.

[0032] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
