[0030] Combination Figures 1 to 5 As shown, a seat adjustment handle without a cover provided by the utility model comprises a handle 1 and a connecting member 2 .

[0031] Combination Figures 1 to 5 As shown, the handle 1 includes an integrally formed shell 11 and a snap-in slot 12, the shell 11 is a shell with uniform wall thickness, the snap-in slot 12 is located on the inner side of the shell 11, the snap-in slot 12 is composed of a polygonal side wall and reinforcing ribs, and the polygonal side wall is provided with a snap-in hole; the connecting member 2 is integrated in the adjusting device, the connecting member 2 is provided with an extension section 21 extending out of the adjusting device and passing through the seat guard plate to connect to the snap-in slot 12, the extension section 21 is a polygonal cylinder, and the outer dimension of the extension section 21 is the same as the inner dimension of the polygonal side wall of the snap-in slot 12, and the side wall of the extension section 21 is provided with a hook to snap into the snap-in hole; the shell 11 is against the seat guard plate, and the snap-in slot 12 passes through the seat guard plate and is close to the adjusting device.

[0032] In this embodiment, the polygonal snap-in groove 12 and the polygonal extension section 21 are connected to ensure the transmission of driving force, the shell 11 with uniform wall thickness ensures the quality of the appearance, and the snap-in connection method eliminates the blocking feature. The snap-in groove 12 passes through the seat guard plate close to the adjustment device, which increases the contact area between the snap-in groove 12 and the extension section 21, reduces the influence of use fatigue on the shape of the snap-in groove 12, and reduces the risk of loosening, falling off and other problems.

[0033] In some embodiments, in combination Figures 1 to 3 As shown, the side walls of the shell 11 are provided with a draft angle, and the opening end of the shell 11 is larger. After the draft angle is increased, when the driver pulls the handle 1, a component force is generated to press the handle 1, thereby reducing the risk of falling off during use.

[0034] In some embodiments, in combination Figure 4 As shown, the snap-in groove 12 also includes a snap-in plate, which is integrally formed at the edge of the snap-in hole. The snap-in plate and the hook on the side wall of the extension section 21 form a snap-in relationship, one end of the snap-in plate fits into the inner wall of the snap-in groove 12, and the other end of the snap-in plate is flush with the outer wall of the reinforcing rib.

[0035] In this embodiment, the snap-in plate and the snap-in hook form a snap-in relationship to increase the area and thickness of the snap-in joint and improve its service life. The snap-in groove 12 has many limitations due to being formed by injection molding, which results in limited area and thickness of the snap-in joint.

[0036] In some embodiments, in combination Figure 4As shown, the snap-in holes are distributed at intervals on the polygonal side wall, and one snap-in hole is provided for every two adjacent side walls on the polygonal side wall. Increasing the number of snap-in holes is the simplest method to strengthen the connection between the handle 1 and the connector 2, but the establishment of the snap-in holes will reduce the structural strength of the snap-in groove 12. The method of spacing distribution can well balance the relationship between the two.

[0037] In some embodiments, in combination Figure 3 As shown, the handle 1 also includes a shell reinforcement rib 13, which is integrally formed on the inner side of the shell 11. The volume of the shell reinforcement rib 13 does not exceed the maximum outer contour of the shell 11, and the wall thickness of the shell reinforcement rib 13 is uniform and does not exceed two-thirds of the wall thickness of the shell 11.

[0038] In this embodiment, the role of the shell reinforcement 13 is to increase the structural strength of the shell 11, and limit the wall thickness of the shell reinforcement 13 to no more than two-thirds of the wall thickness of the shell 11, which can reduce the risk of large surface defects on the appearance of the shell 11 caused by the establishment of the shell reinforcement 13. The surface defects are mainly caused by the fact that the wall thickness at the connection between the shell 11 and the shell reinforcement 13 is different from the normal wall thickness of the shell 11, resulting in the shrinkage rate at the connection being different from that at other positions, thereby causing surface defects such as shrinkage marks.

[0039] In some embodiments, in combination Figure 3 As shown, the shell reinforcement ribs 13 include straight ribs and annular ribs. The intersections of the straight ribs are transitionally connected together by annular ribs. The wall thickness at the intersections of the straight ribs will be significantly different from other positions, resulting in defects in the appearance of the shell 11. The annular ribs are transitionally connected together at the intersections of the straight ribs, which can ensure the uniformity of the wall thickness to a certain extent. As the number of straight ribs at the same intersection increases, the effect of the annular ribs becomes more obvious.

[0040] In some embodiments, in combination Figure 3 , Figure 4 As shown, the reinforcement rib of the snap-in groove 12 is provided with a draft angle, and the reinforcement rib is larger on the side close to the housing 11. Although the increase in the length of the snap-in groove 12 ensures the connection effect, the requirement for the connection strength at the root of the snap-in groove 12 is also increased, and the size of the reinforcement rib at the root of the snap-in groove 12 needs to be increased. However, reinforcement ribs of too large size are also a burden, especially since the head of the snap-in groove 12 does not have such a large strength requirement, so the draft angle of the reinforcement rib design becomes a good solution.

[0041] In some embodiments, in combination Figure 3As shown, the wall thickness of the snap-in slot 12 at any location does not exceed two-thirds of the wall thickness of the outer shell 11. The snap-in slot 12 is one of the main components of the handle 1. The larger volume of the snap-in slot 12 has a greater impact on the appearance of the outer shell 11. Limiting the wall thickness of the snap-in slot 12 can effectively reduce the appearance defects on the outer surface of the outer shell 11.

[0042] In some embodiments, the handle 1 is formed in one step by injection molding, which can ensure the connection stability between the shell 11 and the snap-in groove 12, and the production process is simpler, which is conducive to large-scale production.

[0043] In some embodiments, in combination Figure 5 As shown, the polygonal outer contour of the extension section 21 is provided with rounded corners, and the rounded corners and the snap-in groove 12 form an air-avoiding corner structure. After being assembled together, a gap is generated between the edge of the extension section 21 and the edge of the snap-in groove 12 due to the different chamfer sizes, which is the air-avoiding corner structure. The air-avoiding corner structure is conducive to the discharge of air inside the snap-in groove 12, avoiding the generation of air pressure problems during the installation process that lead to installation difficulties.

[0044] Working process: the driver pulls the handle 1, and the handle 1 transmits the pulling force by the polygonal side wall of the clamping groove 12 and the polygonal side edge of the extension section 21, and the connecting member 2 rotates to drive the adjusting device.

[0045] In this process, the shell 11 with uniform wall thickness ensures the quality of the appearance, the snap-on connection method eliminates the blocking feature, and the snap-on groove 12 passes through the seat guard plate close to the adjustment device to increase the length of the snap-on groove 12 and increase the contact area between the snap-on groove 12 and the extension section 21.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
