DETAILED DESCRIPTION
[0028] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.
[0029] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it may be directly on the other component or there may also be a central component. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may be a central component at the same time. The terms "vertical", "horizontal", "up", "down", "left", "right", "side", "top", "bottom" and similar expressions used in the specification of this application are only used to describe the various example structural parts and elements of this application, but these terms are used here for the purpose of convenience of explanation and are determined based on the example orientations shown in the accompanying drawings, and do not represent the only implementation method. Since the embodiments disclosed in the application can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. Throughout the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.
[0031] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it can mean that the first feature is directly in contact with the second feature, or the first feature and the second feature are indirectly in contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it can mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is higher in level than the second feature. When a first feature is "below," "below," or "below" a second feature, it can mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is lower in level than the second feature.
[0032] Unless otherwise defined, all technical and scientific terms used in the specification of this application have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more of the relevant listed items.
[0033] See also Figures 1 to 4 The present application provides a connection structure. This connection structure is used in an automobile. The automobile includes an interior trim panel 3, an inner sheet metal panel 4, an outer sheet metal panel 5, and the above-mentioned connection structure. This connection structure is used to connect the interior trim panel 3 and the inner sheet metal panel 4.
[0034] like Figures 1 to 4 As shown, the connection structure includes a first clamping portion 1 and a second clamping portion 2 connected in sequence along a first direction A. The first clamping portion 1 is provided with a first clamping groove 101 for clamping the interior trim panel 3. The first clamping groove 101 extends along the first direction A. The first clamping portion 1 has a first opening 1021 in the first direction A for partially inserting the interior trim panel 3 into the first clamping groove 101. The second clamping portion 2 is provided with a second clamping groove 201 for clamping the inner sheet metal panel 4. The direction intersecting the first direction A is defined as the second direction. The second clamping groove 201 extends along the second direction and has a second opening 2021 in the second direction for partially inserting the inner sheet metal panel 4 into the second clamping groove 201.
[0035] In one embodiment, the first direction A and the second direction form an acute angle. In this embodiment, the first direction A and the second direction are substantially perpendicular. In other words, the aforementioned connection structure achieves a substantially perpendicular connection between the interior trim panel 3 and the inner sheet metal panel 4. It should be noted that "substantially perpendicular" includes, but is not limited to, perpendicular and may also deviate slightly from perpendicular.
[0036] It can be understood that when connecting the interior trim panel 3 and the inner sheet metal panel 4, it is only necessary to clamp a portion of the interior trim panel 3 in the first clamping groove 101 of the connecting structure, and a portion of the inner sheet metal panel 4 in the second clamping groove 201 of the connecting structure. This makes the entire assembly process convenient and efficient, saving assembly time. The arrangement of the first and second clamping grooves makes the assembled interior trim panel and inner sheet metal panel more compact, reducing the matching gap between the interior trim panel and surrounding components, minimizing abnormal noise, and maximizing the use of the vehicle body interior space, avoiding layout conflicts caused by space constraints.
[0037] like Figure 3 and Figure 4 As shown, the second clamping portion 2 includes a first clamping plate 21 and a second clamping plate 22 arranged opposite each other, and a connecting plate 23 connecting the first clamping plate 21 and the second clamping plate 22. The connecting plate 23 is arranged opposite the second opening 2021. A second clamping groove 201 is defined between the first clamping plate 21 and the second clamping plate 22. The first clamping plate 21 is located on the side of the second clamping plate 22 facing away from the first clamping groove 101. Therefore, the second clamping plate 22 and the first clamping plate 21 are arranged sequentially along the first direction A. The first clamping portion 1 is connected to the second clamping plate 22.
[0038] The direction in which the inner sheet metal plate 4 enters the second clamping groove 201 is defined as the third direction B. The second direction is in the same direction or opposite direction to the third direction B. The distance between the first clamping plate 21 and the second clamping plate 22 at the corresponding second clamping groove 201 gradually increases along the third direction B.
[0039] In one embodiment, only the second clamping groove 201 is formed between the first clamping plate 21 and the second clamping plate 22. In this embodiment, in addition to the second clamping groove 201, a first slot 202 is also formed between the first clamping plate 21 and the second clamping plate 22. The first slot 202 and the second clamping groove 201 are arranged sequentially along the third direction B, with the second opening 2021 located at the first slot 202. The spacing between the first clamping plate 21 and the second clamping plate 22 corresponding to the first slot 202 gradually decreases along the third direction B.
[0040] It can be understood that the presence of the first slot 202 facilitates the insertion of the inner sheet metal plate 4 into the second clamping groove 201 .
[0041] In order to form the second clamping groove 201 and the first slot 202, in one embodiment, the second clamping plate 22 is V-shaped with its opening facing away from the first clamping plate 21. Figure 3 As shown, the first clamping plate 21 is in a V-shape with an opening facing away from the second clamping plate 22 .
[0042] A first retaining structure 24 is provided between the inner sheet metal plate 4 and the second clamping portion 2 to prevent the inner sheet metal plate 4 and the second clamping portion 2 from disengaging. The first retaining structure 24 comprises a first latching portion and a second latching portion that engage with each other. The first latching portion is located on the inner sheet metal plate 4, while the second latching portion is provided on the first clamping plate 21 or the second clamping plate 22 and is at least partially located within the second clamping groove 201.
[0043] In one embodiment, the first engaging portion is a slot 41 formed on the first clamping plate 21 or the second clamping plate 22, and the second engaging portion is a lug 212 formed on the inner sheet metal plate 4. In another embodiment, the first engaging portion is a first buckle formed on the first clamping plate 21 or the second clamping plate 22, the first buckle being located in the second clamping groove 201, and the second engaging portion is a second buckle formed on the inner sheet metal plate 4.
[0044] In one embodiment, the first engaging portion is a slot 41 formed on the inner sheet metal plate 4, and the second engaging portion is a lug 212 that can be inserted into the slot 41. In this embodiment, the first clamping plate 21 is provided with a through hole 211 extending along its wall thickness. The lug 212 is provided on the edge of the through hole 211 near the second opening 2021. The presence of the through hole 211 facilitates the integral formation of the lug 212 and prevents interference with the lug 212 during elastic deformation. The lug 212 gradually tilts toward the inner sheet metal plate 4 along the third direction B. In another embodiment, the through hole 211 and the lug 212 are both located on the second clamping plate 22.
[0045] It is understood that the lug 212 is elastically deformable relative to the first clamping plate 21 along the first direction A. During the insertion of the inner sheet metal panel 4 into the second clamping groove 201 , the lug 212 abuts against the inner sheet metal panel 4 . Once the inner sheet metal panel 4 is fully inserted, the lug 212 is located within the retaining groove 41 , thereby better restraining the inner sheet metal panel 4 and the second clamping portion 2 , preventing the inner sheet metal panel 4 from separating from the second clamping portion 2 .
[0046] In another embodiment, neither the first clamping plate 21 nor the second clamping plate 22 has the through hole, and the lug 212 is directly formed on the first clamping plate 21 or the second clamping plate 22 .
[0047] The first clamping portion 1 includes a first clamping piece 11 and a second clamping piece 12 spaced apart along the second direction, and a first clamping groove 101 is defined between the first clamping piece 11 and the second clamping piece 12 .
[0048] In this embodiment, the second clamping plate 22 is provided with an opening 220 extending through its wall thickness. The first clip 11 is positioned at the edge of the opening 220, near the second opening 2021, and the second clip 12 is connected to the edge of the second opening 2021. It will be appreciated that the presence of the opening 220 facilitates the integral formation of the first clip 11 and increases its reliability. If the first clip 11 were directly welded to the second clamping plate 22, the strength of the weld would be limited, and the connection between the first clip 11 and the second clamping plate 22 would be more complicated.
[0049] In another embodiment, the second clamping plate 22 does not have the opening 220 , the first clamping piece 11 and the second clamping piece 12 are both arranged along the first direction, and the first clamping piece 11 and the second clamping piece 12 are both connected to the second clamping plate 22 .
[0050] A second retaining structure 13 is provided between the first clamping portion 1 and the interior trim panel 3 to prevent the first clamping groove 101 and the interior trim panel 3 from disengaging from each other. The second retaining structure 13 comprises a stopper and a locking portion that engage with each other. The locking portion is provided on the first clip 11 or the second clip 12 and is at least partially located within the first clamping groove 101. The stopper is provided on the interior trim panel 3.
[0051] In one embodiment, the locking portion is a stopper opening provided on the first clip 11 or the second clip 12, and the stopper is a buckle provided on the interior trim panel 3. In another embodiment, the locking portion is a buckle formed on the first clip 11 or the second clip 12, and the stopper is a stopper opening provided on the interior trim panel 3.
[0052] In one embodiment, the locking portion is a recessed area 121 formed on the inner wall of the first clip groove 101. The wall of the interior trim panel 3 facing the recessed area 121 is defined as the first wall 30. The retaining portion is a flange 311 disposed on the first wall 30 and capable of being restrained within the recessed area 121. In this embodiment, the second clip 12 has an uneven shape and includes the recessed area 121 and the protrusion 122. The protrusion 122 and the recessed area 121 are arranged sequentially along the first direction A. When the connection structure is connected to the interior trim panel 3, the protrusion 122 is located on the side of the flange 311 facing away from the second clip groove 201. In another embodiment, the first clip 11 has an uneven shape, with both the recessed area 121 and the protrusion 122 located on the first clip 11.
[0053] It is understood that the first clip 11 and the second clip 12 are elastically deformable along the second direction. When the interior trim panel 3 is inserted into the first clip groove 101, the flange 311 abuts against the plate where the recessed area 121 is located. Once the interior trim panel 3 is fully inserted, the flange 311 is located within the recessed area 121, thereby better restraining the interior trim panel 3 and the first clamping portion 1, preventing the interior trim panel 3 from separating from the first clamping portion 1.
[0054] Furthermore, a second slot 102 is defined between the first clip 11 and the second clip 12. The second slot 102 and the first clip groove 101 are sequentially arranged along the first direction A. The first opening 1021 is located in the second slot 102. The spacing between the first clip 11 and the second clip 12 at the corresponding second slot 102 gradually decreases along the first direction A.
[0055] It is understandable that the existence of the second slot 102 facilitates the insertion of the interior trim panel 3 into the first clamping groove 101 .
[0056] The interior trim panel 3 includes a first leg 31 and a second leg 32 spaced apart along the second direction. When the connection structure is connected to the interior trim panel 3, a portion of the first leg 31 is located within the first clamping groove 101, and the flange 311 is located on the first leg 31. The region 33 of the interior trim panel 3 between the first leg 31 and the second leg 32 is positioned opposite a portion of the second clamping portion 2, with the second opening 2021 facing away from the second leg 32. In this embodiment, the first clip 11 is located between the first leg 31 and the second leg 32. The second clamping portion 2 is located between the outer sheet metal panel 5 and the first leg 31.
[0057] It can be understood that the above-mentioned connection structure makes the arrangement of the interior trim panel 3 and the inner sheet metal panel 4 more compact, which can reduce the distance between the connection structure and the outermost edge of the second support leg 32 and the distance between the connection structure and the outer sheet metal panel 5, thereby maximizing the utilization of the interior space of the automobile body.
[0058] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0059] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of patent protection for the present application shall be determined by the appended claims.
