Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts assembly, in particular to an initial positioning structure which is convenient for assembling movable parts. Background Art

[0002] During the assembly process of the movable parts, there is a positioning relationship between the two movable parts, and the relative positions of the two must be kept consistent. In the prior art, a high-position positioning structure is usually used to limit the assembly of the movable parts. For example, the Chinese invention patent with the publication number "CN110509886A" discloses a one-time fixed position structure, including a car center column trim and a slide plate, a circular boss is designed at the upper end of the slide plate, and a C-shaped groove is set at the upper end of the car center column trim. Through the mutual engagement and disengagement of the boss and the C-shaped groove, the technical effect of limiting and fixing before assembly and sliding freely after assembly is achieved. However, during the assembly alignment process, the movable parts are often not in the initial highest position, and they need to be manually adjusted to the high position many times. During the adjustment process, since the pre-limit is an elastic hook structure, the reliability is low, and it is not easy to reset after sliding up, resulting in the inability to effectively align the movable parts, and the movable parts are easy to slide down due to their own weight. During assembly, the operator needs to press them all the time, which affects the assembly efficiency and is easy to be installed in place. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model. In the utility model, unless otherwise stated, the directional words used, such as "upper" and "lower", etc., generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings.

[0018] The utility model provides an initial positioning structure for assembling a movable part, comprising a fixed part and a movable part, wherein the movable part is slidably mounted to the fixed part so that the movable part can slide up and down relative to the fixed part to reciprocate between the highest position and the lowest position.

[0019] The movable part is provided with a first limiting protrusion, and the fixed part is provided with a second limiting protrusion. When the movable part slides down to the lowest position, the first limiting protrusion can abut against the second limiting protrusion to limit the sliding of the movable part, thereby limiting the movable part to the lowest position, which is convenient for the alignment installation of the movable part; even if the movable part is not in the lowest position during assembly, the movable part can quickly slide down to the lowest position under the action of its own weight and return to the initial assembly position. Adjusting the traditional high-position limit to the lowest-position one-way limit can not only improve the reliability of the limit and facilitate the rapid resetting of the movable part, but also prevent the movable part from sliding down due to its own weight during the assembly process, thereby improving the assembly efficiency.

[0020] As a specific implementation method, Figure 1 , Figure 2 As shown, the fixed part in the embodiment of the utility model is a pillar trim 1, and the movable part is a seat belt slide plate 2, wherein the pillar trim 1 is fixedly mounted on the vehicle body, the seat belt slide plate 2 is slidably mounted on the inner side of the pillar trim 1, and can slide up and down relative to the pillar trim 1 to reciprocate between the highest position and the lowest position; the seat belt slide plate 2 is provided with a connecting portion 3 for aligning and connecting with the seat belt sliding mechanism on the vehicle body.

[0021] like Figure 3 , Figure 4 As shown, both sides of the seat belt slide plate 2 are respectively provided with slide rails 4 extending along the length direction thereof, and both sides of the inner side surface of the pillar trim panel 1 are respectively provided with limit plates 5 extending along the length direction thereof, and a slide groove 6 is formed between the limit plate 5 and the inner side surface of the pillar trim panel 1, and the slide rails 4 on both sides of the seat belt slide plate 2 can be inserted into the corresponding slide grooves 6 on both sides of the pillar trim panel 1 and slidably cooperate with the slide grooves 6, so that the seat belt slide plate 2 can slide up and down relative to the pillar trim panel 1.

[0022] A first limiting protrusion 7 is provided at the upper end of the slide rail 4, and a second limiting protrusion 8 is provided at the upper end of the limiting plate 5. When the seat belt slide plate 2 slides down to the lowest position, the first limiting protrusion 7 can abut against the second limiting protrusion 8 to limit the seat belt slide plate 2 from sliding down, thereby limiting the seat belt slide plate 2 to the lowest position, making it convenient for the seat belt slide plate 2 to be aligned and connected with the seat belt sliding mechanism on the vehicle body.

[0023] Furthermore, in the embodiment of the utility model, a plurality of reinforcing ribs 9 are arranged at intervals along the length direction of the limiting plate 5 between the limiting plate 5 and the inner side surface of the pillar trim panel 1. The reinforcing rib 9 located at the uppermost end of the limiting plate 5 can be directly used as the second limiting protrusion 8 to abut against the sliding first limiting protrusion 7.
