Description

Technical Field

[0001] This utility model belongs to the field of automotive seat component assembly technology, specifically relating to a novel assembly mechanism of connecting rod and retaining ring. Background Technology

[0002] In the production of car seat backrest frames, the assembly accuracy of the frame adjuster, connecting rod and retaining ring directly determines the stability of the adjuster's operation; the retaining ring needs to be precisely fitted into the preset position of the connecting rod and maintain a fixed distance from the lower plate of the frame adjuster in order to avoid abnormal friction between the three when the motor is running. The existing assembly technology has the following defects: (1) It lacks a dedicated positioning structure for the connecting rod, which is easy to shift during the assembly process, resulting in misalignment between the retaining ring and the connecting rod; (2) It only positions the retaining ring or the lower plate of the frame adjuster as independent parts, without establishing a three-way collaborative positioning system. Currently, the positioning of the retaining ring is either done by directly pressing the adjuster with the machine push or by fixing the machine push movement length. The relative position of the retaining ring and the lower plate of the frame adjuster is easy to deviate, resulting in the retaining ring assembly position being too close or too loose from the frame adjuster; (3) Since the relative position positioning of the lower plate of the frame adjuster, retaining ring and connecting rod cannot be guaranteed, it is impossible to flexibly adjust according to the slight changes in the relative position of the connecting rod, retaining ring and the lower plate of the frame adjuster of different specifications, resulting in poor versatility.

[0003] The aforementioned defects cause jamming or abnormal noise between the retaining ring and the connecting rod, and between the lower plate of the seat back motor and the seat back motor, reducing the user experience of the seat and the lifespan of the seat adjuster, and failing to meet the requirements of high-precision assembly. Utility Model Content

[0004] This utility model aims to provide a novel assembly mechanism for connecting rods and retaining rings, which has high assembly accuracy and strong adaptability, and solves the problem of insufficient assembly accuracy, abnormal noise, and jamming caused by the lack of a coordinated positioning system among the connecting rods, retaining rings, and the lower plate of the frame angle adjuster.

[0005] Therefore, the technical solution adopted by this utility model is as follows: a novel assembly mechanism for a connecting rod and a retaining ring, including a front push drive assembly and a pressure head installed at the pushing end of the front push drive assembly. The pressure head includes a retaining ring positioning component and a reference positioning component, which are sequentially fitted from back to front. The retaining ring positioning component includes a retaining ring mounting disc located at the rear end and a retaining ring placement column located at the front end and extending horizontally outward along the axis of the retaining ring mounting disc. The front end of the retaining ring placement column is provided with a retaining ring placement groove for placing the retaining ring, and a retaining ring detection sensor is installed on the side wall of the retaining ring placement groove, and a connecting rod pushing component is installed at the bottom. The reference positioning component is provided with a through hole in the center for the retaining ring placement column to pass through. An adjusting shim is installed between the retaining ring mounting disc and the front top end of the front push drive assembly, and an adjusting shim is installed between the retaining ring mounting disc and the reference positioning component. When the front push drive assembly pushes the pressure head until the front end of the reference positioning component is in contact with the outer wall of the frame adjuster, the frame connecting rod passes through the retaining ring and inserts into the retaining ring placement groove and is held in place by the connecting rod pushing component, so that the retaining ring is installed in the preset position of the frame connecting rod.

[0006] As a preferred embodiment of the above solution, the reference positioning component includes a reference mounting disc located at the rear end and flush with the retaining ring mounting disc, and an adjuster clamping component located at the front end, which is mirror-symmetrical to the left and right and extends horizontally outward. The front end of the adjuster clamping component matches the arc contour of the circular groove on the outer wall of the lower plate of the frame adjuster. The structure is reasonably designed, thereby ensuring that the front end of the adjuster clamping component fits the lower plate of the frame adjuster and is not interfered with by other positions.

[0007] A further preferred embodiment is that the connecting rod pusher is installed at the bottom of the retaining ring mounting groove by a pusher screw passing through the adjusting shim, which is convenient to install and flexible to adjust.

[0008] More preferably, the front top drive assembly includes a mounting base, a booster component that moves longitudinally along the mounting base, and a drive cylinder that provides driving force for the booster component. The mounting base has a limiting block at the front end and slide rails symmetrically arranged on the top left and right. The booster component includes a movable base that moves along the slide rail, an inverted "T"-shaped connector mounted on the movable base, and a pressure head mounting column mounted on the inverted "T"-shaped connector. The drive cylinder is mounted on the rear side of the mounting base through a cylinder mounting seat and is connected to the booster component. When the drive cylinder pushes the booster component, it synchronously drives the pressure head forward. The structure is interlocking and reasonably designed.

[0009] More preferably, the retaining ring positioning component, the reference positioning component, and the pressure head mounting post are all connected by threads, and the first adjusting shim and the second adjusting shim are both provided with notches to facilitate the passage of the screw, so that the connection is stable.

[0010] More preferably, a height adjustment shim is installed between the "T"-shaped connector and the pressure head mounting column, and a longitudinal auxiliary mounting block is installed on the left side of the mounting base. A position adjustment shim is provided between the mounting base and the longitudinal auxiliary mounting block. A row of strip-shaped mounting holes is provided at intervals on the left and right sides of the mounting base, thereby realizing the left, right and up and down position adjustment of the booster, ensuring that the connecting rod and the retaining ring are on the same axis, and facilitating the assembly of the retaining ring.

[0011] The beneficial effects of this utility model are:

[0012] (1) Compared with the existing system that does not establish a coordinated positioning system for the connecting rod, the retaining ring, and the lower plate of the frame angle adjuster, this solution cleverly uses the retaining ring positioning component and the reference positioning component. The reference positioning block takes the lower plate of the angle adjuster as the reference, and the front end of the reference positioning component fits against the outer wall of the frame angle adjuster. The frame connecting rod passes through the retaining ring and is inserted into the retaining ring mounting slot and is held in place by the connecting rod push component, so as to achieve coordinated positioning of the connecting rod, the retaining ring, and the lower plate of the frame angle adjuster. This ensures that the retaining ring is installed in the preset position of the frame connecting rod and that the distance between the retaining ring assembly position and the frame angle adjuster is not too tight or too loose.

[0013] (2) The precise positioning of the connecting rod, retaining ring, and lower plate of the frame adjuster avoids abnormal friction between the retaining ring and the connecting rod and the lower plate of the adjuster when the motor is running, ensuring smooth operation of the adjuster without jamming or abnormal noise, improving the user experience of the seat and the life of the adjuster; moreover, the thickness of the adjusting shim 1 and adjusting shim 2 can be flexibly adjusted according to different frame specifications to adjust the relative position of the connecting rod, retaining ring and the lower plate of the frame adjuster, which has high adaptability and does not require replacement of the entire mechanism and equipment, reducing equipment costs.

[0014] (3) The front top drive component is linked with the reference positioning block, reducing manual intervention. After the connecting rod and the retaining ring are pre-positioned, no secondary adjustment is required, which improves assembly efficiency and batch consistency. The assembly efficiency is high and meets the needs of large-scale production.

[0015] In summary, this utility model has the advantages of strong adaptability, accurate positioning, elimination of abnormal noise and jamming, reduced equipment costs, and high assembly efficiency. Attached Figure Description

[0020] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0021] Combination Figure 1 — Figure 4 As shown, a novel assembly mechanism for a connecting rod and a retaining ring consists of a front push drive assembly 1 and a pressure head installed at the push end of the front push drive assembly 1.

[0022] The pressure head consists of a retaining ring positioning component 2 and a reference positioning component 3, which are sequentially assembled from back to front.

[0023] The retaining ring positioning component 2 consists of a retaining ring mounting disc 22 located at the rear end and a retaining ring placement post 21 located at the front end and extending horizontally outward along the axis of the retaining ring mounting disc 22.

[0024] The front end of the retaining ring mounting post 21 is provided with a retaining ring mounting groove for mounting retaining ring a, and a retaining ring detection sensor 6 is installed on the side wall of the retaining ring mounting groove, and a connecting rod pusher is installed at the bottom.

[0025] The reference positioning component 3 has a through hole in the center for the card ring mounting post 21 to pass through.

[0026] An adjusting shim 7 is installed between the retaining ring mounting disc 22 and the front top of the front drive assembly 1.

[0027] An adjusting shim 28 is installed between the retaining ring mounting disc 22 and the reference positioning part 3.

[0028] When the top drive assembly 1 pushes the pressure head to the front end of the reference positioning part 3 and it fits against the outer wall of the skeleton angle adjuster b, the skeleton connecting rod c passes through the retaining ring a and is inserted into the retaining ring mounting groove and is held in place by the connecting rod pusher, so that the retaining ring a is installed in the preset position of the skeleton connecting rod c.

[0029] The reference positioning component 3 consists of a reference mounting disc 31 located at the rear end and flush with the retaining ring mounting disc 22, and an angle adjuster clamping component 32 located at the front end, which is mirror-symmetrical to the left and right and extends horizontally outward.

[0030] The front end of the angle adjuster clamping part 32 matches the arc contour of the circular groove on the outer wall of the lower plate of the frame angle adjuster b.

[0031] The front drive assembly 1 consists of a mounting base 11, a booster 12 that moves longitudinally along the mounting base, and a drive cylinder 13 that provides driving force for the booster 12.

[0032] The mounting base 11 has a limit stop 112 at the front end and slide rails 111 symmetrically arranged on the top left and right.

[0034] The drive cylinder 13 is mounted on the rear side of the mounting base 11 via a cylinder mounting seat and is connected to the booster 12. When the drive cylinder 13 pushes the booster 12, it synchronously drives the pressure head forward.

[0035] The retaining ring positioning component 2, the reference positioning component 3, and the pressure head mounting column 122 are all connected by threads.

[0036] Both adjusting shim 7 and adjusting shim 8 have notches to facilitate the passage of the screw.

[0037] A height adjustment shim is installed between the "T"-shaped connector 122 and the pressure head mounting column 123. A longitudinal auxiliary mounting block is installed on the left side of the mounting base 11, and a position adjustment shim is provided between the mounting base 11 and the longitudinal auxiliary mounting block.

[0038] The mounting base 11 has a row of strip-shaped mounting holes spaced at intervals on the left and right sides. Combined with the height adjustment shims, the left, right and up and down positions of the booster 12 can be adjusted to ensure that the connecting rod and the retaining ring are on the same axis, which facilitates the assembly of the retaining ring.

[0039] The connecting rod pusher is installed at the bottom of the retaining ring mounting groove by using a pusher screw 5a passing through the adjusting shim 3 5b.

[0040] Install the retaining ring positioning component 2 onto the front top drive assembly 1 using adjusting shims 1 7 and bolts; then connect the reference positioning component 3 to the retaining ring mounting disc 22 using adjusting shims 2 8 and bolts; finally, install the push screw 5a into the retaining ring mounting groove using adjusting shims 3 5b, and mount the retaining ring detection sensor 6 onto the side wall of the retaining ring mounting groove and lock it with a stop bolt.
