DETAILED DESCRIPTION

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0023] like Figure 1-Figure 5 As shown, the blocking device of the seat recliner 4 of the embodiment of the utility model comprises a body 1 , an outer blocking piece 3 and an inner blocking piece 2 .

[0024] Specifically, Figure 1 and Figure 5 As shown, the main body 1 is used to be inserted into the force transmission rod mounting hole of the seat back adjuster, and the outer blocking member 3 and the inner blocking member 2 are connected to the main body 1 at intervals along the length direction of the main body 1, and the outer blocking member 3 is used to block or cover the opening at one end of the force transmission rod mounting hole, and the inner blocking member 2 is used to block or cover the opening at the other end of the force transmission rod mounting hole, and the outer blocking member 3 and / or the inner blocking member 2 are detachably connected to the main body 1.

[0025] Therefore, before electrophoresis of the automobile seat frame, the seat recliner 4 sealing device of the present application can be installed at the mounting hole of the force transmission rod, and the inner sealing piece 2 and the outer sealing piece 3 can be used to respectively cover the openings at both ends of the mounting hole, thereby preventing the electrophoretic paint from entering the recliner 4. Furthermore, since the inner sealing piece 2 and / or the outer sealing piece 3 are in a detachable mating relationship with the main body 1, the device can be removed from the recliner 4 after electrophoresis for reuse.

[0026] The seat recliner 4 blocking device of the embodiment of the utility model has a main body 1 which is used to be inserted into the force transmission rod mounting hole of the seat back adjuster, and the outer blocking piece 3 and the inner blocking piece 2 are detachably connected to the main body 1 and respectively block the openings at both ends of the mounting port, so that before electrophoresis, the seat recliner 4 blocking device can be first installed at the force transmission rod mounting hole, and the inner blocking piece 2 and the outer blocking piece 3 can be used to respectively cover the openings at both ends of the mounting hole, thereby preventing the electrophoretic paint from entering the recliner 4 and solving the problem of abnormal noise caused by friction between the electrophoretic paint and the connecting rod.

[0027] Furthermore, if Figure 1-Figure 5As shown, the main body 1 has a first end and a second end opposite to each other along its length direction, the outer sealing member 3 is connected to the first end, a guide cone 11 is provided on the main body 1, the guide cone 11 is spaced apart from the first end, and the cross-sectional area of ​​the guide cone 11 gradually increases in the direction approaching the first end, the inner sealing member is sleeved on the main body 1 and can be moved from the second end to the side of the guide cone 11 facing the first end, and the diameter of the side of the guide cone 11 facing the first end is greater than the diameter of the inner hole of the inner sealing member.

[0028] In other words, the inner plugging member 2 is detachably connected to the body 1, and the outer plugging member 3 and the body 1 can be an integral structure or independent structural members assembled together. Taking the assembly of the inner plugging member 2 as an example, when assembling with the angle adjuster 4, the body 1 needs to be passed through the force transmission rod mounting hole first. At this time, the second end of the body 1 is located on the inner side of the angle adjuster 4, and the first end is located on the outer side of the angle adjuster 4. Then, the inner plugging member 2 is inserted from the second end of the body 1 and slides toward the position close to the force transmission rod mounting hole under the guidance of the guide cone 11, until the inner plugging member 2 completely slides over the guide cone 11, the guide cone 11 can stop the inner plugging member 2 to cooperate with the angle adjuster 4 to clamp the inner plugging member 2. At this time, the inner plugging member 2 is fixed and covers the force transmission rod mounting hole. It should be noted that the guide cone 11 and / or the inner plugging member 2 have a certain deformation amount to meet the disassembly and assembly of the inner plugging member 2.

[0029] Preferably, the guide cone 11 is a conical plate surrounding the outer periphery of the body 1. Thus, there is a spacer cavity between the conical plate and the body 1, which can be used as a deformation space to shrink inwards when the inner blocking member 2 slides over the conical plate, thereby reducing the difficulty of disassembly and assembly.

[0030] Preferably, the diameter R of the side of the guide cone 11 facing the first end and the diameter r of the inner hole of the inner plugging member are 0.85≤r / R≤0.95. It should be noted that when the ratio of r / R is too small, there will be a problem of assembly difficulty, and when the ratio of r / R is too large, it may cause the problem of limit failure, and when 0.85≤r / R≤0.95, both the smoothness of disassembly and assembly and the reliability of limit can be taken into account.

[0031] It should be noted that the disassembly and assembly of the inner blocking member 2 and the body 1 is not limited to the above-mentioned method. For example, in other embodiments, the body 1 has an external thread, and the outer blocking member 3 and / or the inner blocking member 2 are threadedly matched with the body 1. Thus, the outer blocking member 3 and the inner blocking member 2 can be disassembled and assembled with the body 1 by screwing in and out, which is simple to operate, and the screw-in position can be flexibly adjusted according to the different models of the recliner 4, and the versatility is high.

[0032] Optionally, the disassembly and assembly methods of the inner blocking member 2, the outer blocking member 3 and the main body 1 may also be other matching forms, which are not limited here.

[0033] Furthermore, if Figure 1 and Figure 2 As shown, the inner sealing member 2 includes a first cover and a second cover. The first cover includes a bottom plate and a first outer ring plate 21 arranged around the outer periphery of the bottom plate and protruding toward the outer sealing member 3. The second cover is a second outer ring plate 22 arranged around the bottom plate and protruding toward the outer sealing member 3. The second outer ring plate 22 is arranged at intervals on the inner side of the first outer ring plate 21. Figure 5 As shown, the inner side surface of the angle adjuster 4 is provided with a clamping plate 41 surrounding the force transmission rod mounting hole, and the first outer ring plate 21 can be used to snap-connect with the clamping plate 41 to fix the inner sealing member 2. In addition, after the main body 1 passes through the force transmission rod mounting hole, in order to ensure the reliability of its sealing, it is usually necessary to arrange a sealing sleeve 5 between the main body 1 and the force transmission rod mounting hole, and one end of the sealing end can be led out toward the inner side of the angle adjuster 4, and the second outer ring plate 22 can press and fix the sealing sleeve 5.

[0034] Preferably, if Figure 2 As shown, the protruding height of the second outer ring plate 22 toward the outer blocking member 3 is greater than the protruding height of the first outer ring plate 21 toward the outer blocking member 3 .

[0035] Furthermore, if Figure 3 As shown, the outer plugging member 3 includes a barrel portion 31 and a plugging portion 32. The barrel portion 31 extends in the same direction as the body 1 and one end of the barrel portion 31 facing the inner plugging block has a matching hole. The plugging portion 32 is connected to the other end of the barrel portion 31, and the first end is detachably inserted into the matching hole. Thus, the outer plugging member 3 can be quickly disassembled and assembled by plugging the matching hole with the body 1, which is simple to operate and has high working efficiency. In addition, when plugging the installation holes of different types of force transmission rods, the outer plugging member 3 can be flexibly replaced.

[0036] Preferably, the matching hole is matched with the first end thread, that is, the first end is provided with an external thread, and the matching hole is provided with an internal thread.

[0037] Preferably, the cross section of the barrel portion 31 is a polygon. Therefore, when the barrel portion 31 is fitted in the force transmission rod mounting hole, the polygonal profile can prevent it from rotating in the mounting hole, thereby ensuring the assembly stability and sealing reliability of the entire plugging device.
