Description

Technical Field

[0001] This utility model belongs to the field of automotive seat slide rail technology, specifically relating to a slide rail material with an anti-detachment structure. Background Technology

[0002] Car seat slide rails are important components for adjusting the front and rear positions of a car. They are made of high-strength steel plates or alloy materials through processes such as stamping, cutting, and bending. They are generally sheet-like structures with specific grooves or flanges. Car seat slide rails are mainly composed of upper slide rail sheets and lower slide rail sheets, and are fixed by a locking mechanism. The locking mechanism includes a rotating shaft, a return spring, and a locking tooth plate.

[0003] The upper slide rail piece is generally fixedly connected to the seat frame, while the lower slide rail piece is rigidly fixed to the body panel with bolts. When adjusting the car seat forward and backward, the upper slide rail piece needs to be frequently slid and locked, relying on a dynamic locking mechanism to fix the upper slide rail piece. However, under frequent locking, the locking tooth plate of the locking mechanism deforms, causing it to fail to lock the slide rail piece. In addition, during a car collision or sudden braking, the seat is subjected to inertial thrust, and the locking tooth plate is subjected to shear force, which can easily deform or break, causing the locking tooth plate to fall off the locked state, resulting in the upper slide rail piece and the lower slide rail piece separating. There are shortcomings that need to be improved.

[0004] Existing seat slide rail components lack a design to prevent the slide rail material from detaching during use. To address this, this application proposes a slide rail material with an anti-detachment structure. Utility Model Content

[0005] The purpose of this utility model is to provide a slide rail material with an anti-detachment structure to solve the problem mentioned in the background art that the seat slide rail component does not have an anti-detachment design for the upper slide rail material.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a slide rail sheet with an anti-detachment structure, comprising...

[0007] The automotive seat slide rail assembly includes a lower slide rail piece and an upper slide rail piece that are slidably connected. The lower slide rail piece has a support strip fixed inside by bolts, and the top of the support strip has equidistantly distributed protrusions welded on it.

[0008] The anti-detachment locking mechanism includes a stabilizing plate fixed to the upper slide rail material by bolts, a limiting cylinder welded to the stabilizing plate, a rotating shaft passing through the limiting cylinder, a reset torsion spring sleeved on the outside of one end of the rotating shaft, and a toothed plate welded to the rotating shaft and equipped with a locking plate.

[0009] The anti-detachment blocking assembly includes a fixed plate welded inside the upper slide rail sheet, a sliding plate that slides through the fixed plate, a movable column whose end is welded to the sliding plate, and a blocking plate whose end is welded to the fixed plate. A pull plate is welded to one end of the sliding plate.

[0011] Preferably, an extension plate is welded to the stabilizing plate, and a clamping spring plate is welded to the extension plate.

[0012] Preferably, a support member is welded to the outer side of the rotating shaft. The support member includes a cylinder and an arc block. The clamping spring plate includes a fixed part and an inclined part. The arc block is in contact with the inclined part.

[0013] Preferably, a right-angled limiting post c is welded to the pressing spring plate, and a return spring sleeved on the outside of the limiting post c is welded to the pressing spring plate.

[0015] Preferably, a groove with a rectangular orthographic projection is formed on the surface of the sliding plate, and the end of the U-shaped movable column passes through the groove, with the movable column being tangent to the surface of the blocking plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 5This utility model provides a technical solution: a slide rail sheet with an anti-detachment structure, including an automotive seat slide rail sheet assembly, comprising a lower slide rail sheet 11 and an upper slide rail sheet 12 slidably connected. When the upper slide rail sheet 12 moves along the length of the lower slide rail sheet 11, the fore-and-aft position of the seat can be changed. A support strip 5 is bolted to the inside of the lower slide rail sheet 11. Equally spaced protrusions 51 are welded to the top of the support strip 5. The protrusions 51 on the support strip 5 serve to limit the blocking plate 61, preventing the fixing plate 61 from... The upper slide rail piece 12 moves, and has an anti-detachment function to prevent the upper slide rail piece 12 from moving; the anti-detachment locking mechanism includes a stabilizing plate 21 fixed to the upper slide rail piece 12 by bolts, a limiting cylinder 22 welded to the stabilizing plate 21, a rotating shaft 23 passing through the limiting cylinder 22, a return torsion spring 24 sleeved on the outside of one end of the rotating shaft 23, and a toothed plate 25 welded to the rotating shaft 23 and having a locking plate. When locking the upper slide rail piece 12, the two ends of the return torsion spring 24 are fixedly connected to the limiting cylinder 22 and the rotating shaft 23 respectively, and the toothed plate 25 is embedded in the lower slide rail piece 12. The toothed groove a inside the plate 11 achieves the effect of fixing the upper slide rail plate 12. When the rotating shaft 23 is manually driven to rotate, the return torsion spring 24 deforms, and the toothed plate 25 leaves the toothed groove a, which facilitates the sliding of the upper slide rail plate 12, thereby making it easier to change the front and rear position of the seat. The anti-detachment blocking component includes a fixed plate 6 welded inside the upper slide rail plate 12, a sliding plate 7 that slides through the fixed plate 6, a movable column 71 with its end welded to the sliding plate 7, and a blocking plate 61 with one end welded to the fixed plate 6. A pull plate is welded to one end of the sliding plate 7. 4. The outer surface of the baffle plate 61 contacts the convex plate 51. The baffle plate 61 is constrained by the convex plate 51 to prevent the fixed plate 6 and the upper slide rail piece 12 from moving. It has the function of preventing the upper slide rail piece 12 from moving. When the pull plate 4 is manually pulled, the sliding plate 7 and the moving column 71 move. The moving column 71 causes the baffle plate 61 to deform, so that there is a gap between the baffle plate 61 and the convex plate 51, which does not affect the sliding of the upper slide rail piece 12. The baffle plate 61 is made of elastic metal material, such as spring steel, and has the function of deformation reset.

[0027] In this embodiment, a toothed groove a is formed on the surface of the lower slide rail piece 11, and a tooth b is welded on the toothed plate 25. The locking plate is the tooth b, which corresponds to the toothed groove a. The toothed plate 25 is embedded in the toothed groove a of the lower slide rail piece 11 to achieve the effect of fixing the upper slide rail piece 12.

[0028] In this embodiment, an extension plate 31 is welded onto the stabilizing plate 21, and a clamping spring plate 32 is welded onto the extension plate 31. A support member 8 is welded onto the outer side of the rotating shaft 23. The support member 8 includes a cylinder and an arc block. The clamping spring plate 32 includes a fixed part and an inclined part. The arc block contacts the inclined part. The clamping spring plate 32 limits the support member 8, thus limiting the rotating shaft 23 and preventing the rotating shaft 23 and the toothed plate 25 from deflecting, thereby causing the toothed plate 25 to disengage from the tooth groove a. Under the limiting action of the clamping spring plate 32, the rotating shaft 23 is kept in a stable state.

[0029] In this embodiment, a right-angled limiting post c is welded onto the pressing spring plate 32, and a return spring 9 is welded onto the pressing spring plate 32 and sleeved on the outside of the limiting post c. The return spring 9 serves to tighten the pressing spring plate 32 and prevent the deformed pressing spring plate 32 from being unable to return to its original position.

[0030] In this embodiment, the baffle plate 61 has a bent structure. The outer surface of the baffle plate 61 is in contact with the protrusion plate 51. The baffle plate 61 is constrained by the protrusion plate 51 to prevent the fixed plate 6 and the upper slide rail sheet 12 from moving.

[0031] In this embodiment, a groove with a rectangular orthographic projection is provided on the surface of the sliding plate 7. The end of the "U"-shaped moving column 71 passes through the groove. The moving column 71 is tangent to the surface of the blocking plate 61. When the pull plate 4 is manually pulled, the sliding plate 7 and the moving column 71 move. The moving column 71 causes the blocking plate 61 to deform, so that there is a gap between the blocking plate 61 and the convex plate 51, which does not affect the sliding of the upper slide rail material 12.

[0032] Working principle and usage process of this utility model:

[0033] When the manually driven rotating shaft 23 is rotated, the reset torsion spring 24 deforms and the toothed plate 25 leaves the tooth groove a, which facilitates the upper slide rail piece 12 to slide along the length direction of the lower slide rail piece 11, thereby making it easier to change the front and rear position of the seat.

[0034] When the rotating shaft 23 rotates, the clamping spring plate 32 restricts the opening member 8, thus restricting the rotating shaft 23 and preventing the rotating shaft 23 and the toothed plate 25 from deflecting, thereby causing the toothed plate 25 to disengage from the tooth groove a;

[0035] When the rotating shaft 23 is released, the return spring 9 pulls the clamping spring plate 32. Under the limiting effect of the clamping spring plate 32, the rotating shaft 23 is kept in a stable state, thereby stabilizing the engagement between the toothed plate 25 and the lower rail material 11.

[0036] While the shaft 23 is manually driven to rotate, the pull plate 4, sliding plate 7 and moving column 71 are manually pulled to move. The moving column 71 causes the blocking plate 61 to deform, so that there is a gap between the blocking plate 61 and the convex plate 51, which does not affect the sliding of the upper slide rail material 12.

[0037] After the upper slide rail sheet 12 moves to the appropriate position, it pushes the pull plate 4, and the deformed blocking plate 61 returns to its original position. The blocking plate 61 then contacts the protruding plate 51. Figure 3 As shown, the baffle plate 61 is constrained by the protrusion plate 51 to prevent the fixed plate 6 and the upper slide rail piece 12 from moving, and has the function of preventing the upper slide rail piece 12 from moving.

[0038] In summary: The seat slide rail component of this application has an anti-detachment design for the upper slide rail piece 12. The blocking plate 61 is limited by the protruding plate 51 and also has deformation capability, which can reduce inertial force, prevent the fixed plate 6 and the upper slide rail piece 12 from moving, prevent the upper slide rail piece 12 from detaching from the lower slide rail piece 11, and press the spring plate 32 to limit the opening member 8, thus limiting the rotating shaft 23 and preventing the rotating shaft 23 and the toothed plate 25 from deflecting.

[0039] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
