Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a positioning and mounting structure and control assembly. Background Technology

[0002] With the development of science and technology, we use all kinds of industrial products in our daily lives. These products are usually assembled from different parts. In order to facilitate assembly and control the appearance quality of the finished product, positioning and installation structures are used in product design.

[0003] In related technologies, the positioning and mounting structure typically includes a base and a base plate. The base is provided with positioning pins and mounting posts, and the base plate is provided with corresponding positioning holes and mounting holes. During assembly, the positioning pins are inserted into the positioning holes to complete the engagement. At this time, the mounting posts abut against the bottom surface of the base plate. The assembly is completed by screwing screws into the mounting holes to engage with the mounting posts.

[0004] However, this approach results in multiple columns with different functions on the base, which makes the positioning and installation structure require a large amount of space. For devices with limited internal space, such as steering wheels, this structure is difficult to apply.

[0005] In view of this, there is an urgent need to provide a positioning and installation structure that can effectively optimize spatial layout and ensure positioning effect. Utility Model Content

[0006] This application provides a positioning and installation structure that enables the positioning column to have both positioning and fastening functions, which can effectively optimize the spatial layout and product structure, while improving the convenience of assembly.

[0007] Firstly, the positioning and installation structure provided in this application adopts the following technical solution:

[0008] A positioning and mounting structure, comprising:

[0009] The substrate has multiple mounting holes;

[0010] A positioning hole is formed on the substrate and communicates with the mounting hole;

[0011] The base has multiple hollow positioning posts that abut against the bottom surface of the substrate, and the multiple positioning posts and multiple mounting holes are coaxially corresponding to each other.

[0012] A limiting part is provided on the positioning post, and extends into the positioning hole when the positioning post abuts against the substrate, so that the positioning post and the substrate are engaged.

[0013] Furthermore, multiple limiting parts are provided, and each of the multiple limiting parts corresponds to one of the multiple positioning posts.

[0014] Furthermore, each of the plurality of limiting portions is divided into two groups, and the two groups of limiting portions are symmetrically arranged relative to the substrate.

[0015] Furthermore, the limiting part is disposed on any of the positioning posts.

[0016] Furthermore, the limiting part is configured as a ring or an arc.

[0017] Furthermore, the outer peripheral surface of the limiting part is tapered, and the diameter of the positioning hole gradually decreases along the insertion direction of the limiting part.

[0018] Furthermore, the limiting part is disposed on the outer peripheral surface of the positioning post; or

[0019] The limiting part is disposed on the end face of the positioning post.

[0020] Furthermore, the end face of the limiting portion is disposed below the top surface of the substrate.

[0021] Secondly, this application provides a control assembly that adopts the above-mentioned positioning and mounting structure.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application integrates the limiting part and the positioning column together, so that the positioning column has the functions of positioning and fixing. The high integration of the two optimizes the spatial layout of the positioning and installation structure. Based on this, the size and complexity of the product can be optimized, and the positioning and installation structure is easier to process.

[0024] 2. In this application, the outer peripheral surfaces of the limiting part and the positioning post are both tapered to facilitate smoother engagement with the substrate. At the same time, the clearance fit between the limiting part and the top of the substrate after insertion into the positioning hole reduces the risk of wear when the positioning post engages with the fastener.

[0028] The following will be combined with the appendix Figure 1-2The technical solution of this application is clearly and completely described. The following embodiments are exemplary and are only used to explain this application, and should not be construed as limiting this application. In the following description, the same reference numerals are used to denote the same or equivalent elements, and repeated descriptions are omitted.

[0030] Furthermore, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] It should also be further understood that the term “and / or” as used in this application refers to any combination of one or more of the listed items, and all possible combinations thereof.

[0032] A positioning and installation structure, referring to Figure 1 and Figure 2 A positioning and mounting structure includes a base plate 1, a base 2, and a hollow positioning post 3. The positioning post 3 is disposed on the base 2, and the base plate 1 has mounting holes 11 that mate with the positioning post 3.

[0033] When the substrate 1 and the base 2 are assembled together, the end face of the positioning post 3 abuts against the bottom surface of the substrate 1, and the positioning post 3 is coaxially arranged with the mounting hole 11. At this time, fasteners (such as screws) can be inserted into the positioning post 3 from the mounting hole 11 for assembly, so that the substrate 1 and the base 2 are assembled together.

[0034] Furthermore, multiple positioning posts 3 are provided, and the multiple positioning posts 3 are evenly distributed on the base 2, and multiple mounting holes 11 are correspondingly opened on the base plate 1. When the base plate 1 and the base 2 are assembled, the multiple positioning posts 3 and the multiple mounting holes 11 are coaxially corresponding to each other.

[0035] By setting multiple positioning posts 3 to correspond one-to-one with fasteners, the fit between the base plate 1 and the base 2 is made more secure. In some embodiments, there may be 2, 4 or 6 positioning posts 3, which are divided into two groups and symmetrically arranged along the length of the base 2.

[0036] Furthermore, referring to Figure 1 The positioning and mounting structure also includes a limiting part 4, and a positioning hole 12 communicating with the mounting hole 11 is also provided on the substrate 1. The limiting part 4 is provided on the positioning post 3, and extends into the positioning hole 12 when the positioning post 3 abuts against the substrate 1, so that the positioning post 3 and the substrate 1 are engaged.

[0037] By integrating a limiting part 4 into the hollow positioning post 3, the positioning post 3 can also function as a fastener and a limiting base plate 1, thereby reducing the number of posts on the base 2 and achieving the effect of optimizing the structure and reducing space occupation.

[0038] It should be noted that this application does not specify the form of the positioning hole 12. The positioning hole 12 can be a fully through hole or a countersunk hole with depth.

[0039] Furthermore, the shape of the limiting part 4 can be specifically configured according to the actual situation, such as ring-shaped, arc-shaped, straight-line-shaped, triangular, square-shaped, etc. In some embodiments, the limiting part 4 can be configured as ring-shaped or arc-shaped to facilitate machining.

[0040] Specifically, refer to Figure 2 In one specific embodiment, the limiting part 4 is set in an arc shape, and the two ends of the limiting part 4 can abut well against the wall surface of the positioning hole 12. After the base 2 and the base plate 1 are engaged, the limiting part 4 can prevent the base plate 1 from rotating relative to the positioning post 3.

[0041] In another specific embodiment, the limiting part 4 is set as a ring. At this time, the outer diameter of the limiting part 4 is smaller than the outer diameter of the positioning post 3, so as to ensure that while the positioning post 3 abuts against the substrate 1, the limiting part 4 can be smoothly engaged in the positioning hole 12.

[0042] It should be noted that the shape of the positioning hole 12 is consistent with that of the limiting part 4, so that when the limiting part 4 extends into the positioning hole 12, it will not be described in detail here.

[0043] Furthermore, based on the arc or ring shape of the limiting part 4, refer to Figure 1 The outer peripheral surface of the limiting part 4 is tapered, and the diameter of the positioning hole 12 gradually decreases along the insertion direction of the limiting part 4. The tapered limiting part 4 provides a guiding function, allowing the limiting part 4 to extend more smoothly into the positioning hole 12 for easier assembly.

[0044] Correspondingly, the outer peripheral surface of the positioning post 3 is tapered. When the limiting part 4 is arc-shaped, the outer peripheral surface of the positioning post 3 and the limiting part 4 transitions smoothly, which facilitates processing and improves the overall integrity between the limiting part 4 and the positioning post 3.

[0045] Furthermore, after the base 2 and the substrate 1 are engaged, the end face of the limiting part 4 is set lower than or flush with the top surface of the substrate 1 so that the fastener can be smoothly inserted into the positioning post 3 to complete the fastening. In this embodiment, the end face of the limiting part 4 is set lower than the top surface of the substrate 1 to form a gap, so as to reduce the risk of wear when the positioning post 3 and the fastener are engaged.

[0046] Furthermore, the number of limiting parts 4 can be specifically set according to the actual situation.

[0047] In some embodiments, a limiting part 4 is provided, and the limiting part 4 is provided on any positioning post 3.

[0048] In some embodiments, multiple limiting parts 4 are provided, and each limiting part 4 corresponds to one of the multiple positioning posts 3. Based on this, the limiting parts 4 can be divided into two groups, just like the positioning posts 3, with the two groups of limiting parts 4 symmetrically arranged relative to the base 2, to facilitate processing.

[0049] It should be noted that when the limiting part 4 is set to a ring shape, the number of limiting parts 4 is set to multiple to ensure the limiting effect of the limiting part 4.

[0050] Furthermore, the position of the limiting part 4 can be specifically set according to the actual situation. For example, in some embodiments, the limiting part 4 is disposed on the end face of the positioning post 3. Or, in some embodiments, the limiting part 4 is disposed on the outer peripheral surface of the positioning post 3.

[0051] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
