[0054] See Figure 1-2 This utility model discloses a fastener 100 for securing parts to a vehicle. The fastener 100 includes a first cantilever 110 and a second cantilever 120. (The last sentence appears to be incomplete and possibly refers to a different application.) Figure 1 and Figure 2 In this diagram, the side of fastener 100 located at the upper part of the figure is referred to as the top 100-T of fastener 100; the upper ends of the first cantilever 110 and the second cantilever 120 are referred to as the first end 110-1 of the first cantilever 110 and the first end 120-1 of the second cantilever 120; and the lower ends of the first cantilever 110 and the second cantilever 120 are referred to as the second end 110-2 of the first cantilever 110 and the second end 120-2 of the second cantilever 120. However, it should be understood that the designations of "first end" and "second end" are merely to distinguish the different ends of the first cantilever 110 and the second cantilever 120. Figure 3 The diagram shows a front view of fastener 100, with a first direction and a second direction shown, which are orthogonal. This is for illustrative purposes only and is not intended to define the direction of use or manufacture of fastener 100. Figure 1As shown, the fastener 100 has a width, which is the width of the first cantilever 110 and the second cantilever 120. In the embodiment shown in the figures, both the first end and the second end of the first cantilever 110 and the second cantilever 120 have substantially the same width, and the two are arranged facing each other. In one implementation, there is a virtual plane along a first direction between the first cantilever 110 and the second cantilever 120, and the first cantilever 110 and the second cantilever 120 are symmetrical with respect to the virtual plane; however, the first cantilever 110 and the second cantilever 120 do not need to have completely identical structures.

[0055] In Figure 1 and Figure 2 the illustrated embodiment, the first cantilever 110 is shown as having a first arm 111 of the first cantilever and a second arm 112 of the first cantilever, the first arm 111 of the first cantilever and the second arm 112 of the first cantilever respectively connect the first end 110-1 of the first cantilever 110 and the second end 110-2 of the first cantilever 110; the second cantilever 120 is shown as having a first arm 121 of the second cantilever and a second arm 122 of the second cantilever, the first arm 121 of the second cantilever and the second arm 122 of the second cantilever respectively connect the first end 120-1 of the second cantilever 120 and the second end 120-2 of the second cantilever 120. The first cantilever 110 and the second cantilever 120 respectively form an annular cantilever of a square-shaped frame.

[0056] In other embodiments, the first cantilever 110 and the second cantilever 120 may have other shapes, and are not necessarily cantilevers of a square-shaped frame.

[0057] The first cantilever 110 and the second cantilever 120 have elasticity, and their first ends are integrated or can be connected together; in one implementation, it can be considered that the first ends 110-1 and 120-1 of the first cantilever 110 and the second cantilever 120 form the top 100-T of the fastener 100.

[0058] The second ends 110-2 and 120-2 of the first cantilever 110 and the second cantilever 120 face each other and are spaced apart; in one implementation, the second ends 110-2 and 120-2 of the first cantilever 110 and the second cantilever 120 abut against each other. When, for example, a plate-shaped member 200 is inserted into the fastener 100, the second end 110-2 of the first cantilever 110 and the second end 120-2 of the second cantilever 120 are spread apart by the plate-shaped member 200, allowing the plate-shaped member 200 to be inserted into the space between the first cantilever 110 and the second cantilever 120, and the second end 110-2 of the first cantilever 110 and the second end 120-2 of the second cantilever 120 clamp the plate-shaped member 200 due to elasticity.

[0059] In one embodiment, the first cantilever 110 and the second cantilever 120 may each include three segments. These three segments are used only to describe the external contours of the first cantilever 110 and the second cantilever 120; however, the first cantilever 110 and the second cantilever 120 can be a single unit. For example, the first segments 111-1 (and 112-1) of the first cantilever 110 and the first segments 121-1 (and 122-1) of the second cantilever 120 are close to the top 100-T of the fastener 100. The first segments of the first cantilever 110 and the second cantilever 120 extend along a second direction (downward in the figure) and gradually separate, such that the external contours of the first segments of the first cantilever 110 and the second cantilever 120 together constitute at least a portion of an A-shape. Figure 1 The outer contour of the first segment can be described as a truncated A-shaped profile. The outer contour of the first segment can have an inclined plane; in another embodiment, it can also be a surface with a certain curvature. The first segment 111-1 of the first cantilever 110 and the corresponding first segment 121-1 of the second cantilever 120 are configured together to form a wedge-shaped outer contour, or as shown in... Figure 1 and 2 The outward "V" shape shown is advantageous, as the wedge-shaped outer contour facilitates the insertion of the first segment of the first cantilever 110 and the second cantilever 120 of the fastener 100 into the mounting hole or opening 300.

[0060] like Figure 1 The second segment 111-2 of the first cantilever 110 continues from the first segment 111-1, and the second segment 111-2 is shaped like an inward "V" as shown in the figure. Due to the configuration of both the first segment 111-1 and the second segment 111-2, both segments provide an arched shape, with the most prominent point of the arch (relative to the second direction) located at the junction of the first segment 111-1 and the second segment 111-2. The second cantilever 120 has a similar configuration. This is advantageous because when the fastener 100 is easily inserted into the mounting hole or opening 300 by the first segments of the first cantilever 110 and the second cantilever 120 through a wedge-shaped or A-shaped profile, the first cantilever 110 and the second cantilever 120 are compressed by the mounting hole or opening 300 due to the arched shape of the first segment 111-1, and gradually undergo elastic deformation. The arched shape of the first segments 111-1 and 122-1 of the first cantilever 110 and the second cantilever 120 allows them to be flattened, thus allowing the fastener 100 to be further inserted into the mounting hole or opening 300. When the fastener 100 is further inserted into the mounting hole or opening 300, after the most prominent point of the junction of the first segment 111-1 and the second segment 111-2 is inserted into the mounting hole or opening 300, the inner "V"-shaped outer profile of the second segment allows the first cantilever 110 and the second cantilever 120 to gradually return to their original shape, gradually returning from a flattened shape to an arched shape (as shown in the image). Figure 7 ).

[0061] The inclination of the outer contours of the second segments 111-2 and 122-2 is greater than that of the first segments 111-1 and 122-1. This is advantageous because when the fastener 100 is pulled out of the mounting hole or opening 300, the second segments 111-2 and 122-2 are steeper, thus requiring greater force to overcome the elastic deformation of the first cantilever 110 and the second cantilever 120 (because the first cantilever 110 and the second cantilever 120 need to be flattened to the same degree as when inserted before they can be pulled out, but the stroke is shortened during pull-out). Therefore, the fastener 100 is easier to insert into the mounting hole or opening 300, but requires greater force to pull out. In other words, the fastener 100 is easier to install into the mounting hole or opening 300 and is not easy to detach, and can be firmly held in the mounting hole or opening 300 to achieve the effect of fixed connection. Only one of the first cantilever 110 and the second cantilever 120 is described here; however, it should be understood that the other cantilever arms have a similar configuration.

[0062] In the embodiments of this utility model, the first segment 111-1 and the second segment 111-2 are mostly flat, while the junction between the two can be an arc-shaped outer surface, or a rounded chamfer, rather than a sharp corner. That is, there is a concave arc between the rounded chamfer and the flat surface of the second segment 111-2. This is advantageous because it can reduce damage to the mounting hole or opening 300 and the fastener 100 itself during the installation and removal of the fastener 100. It can achieve high holding force while ensuring low insertion resistance, and the performance is stable after repeated insertion and removal. It is also easier to operate and improves the user experience.

[0063] In the embodiments of this utility model, the surface of the outer contour of the second segments 111-2 and 122-2 can be a plane or an arc surface.

[0064] The third segments 111-3 and 122-3 of the first cantilever 110 and the second cantilever 120 continue from the second segments 111-2 and 122-2. The third segments 111-3 and 122-3 of the first cantilever 110 and the second cantilever 120 continue from the second segments 111-2 and 122-2 and extend to the second ends 120-2 of the first cantilever 110 and the second cantilever 120, respectively, such that the extension direction of the outer contour of the third segments 111-3 and 122-3 of the first cantilever 110 and the second cantilever 120 forms an angle with the extension direction of the outer contour of the second segments 111-2 and 122-2, so that sliding from the surface of the outer contour of the third segments 111-3 and 122-3 of the first cantilever 110 and the second cantilever 120 to the surface of the outer contour of the second segments 111-2 and 122-2 will be resisted by the second segments 111-2 and 122-2. The angle between the outer contour extension directions of the third segments 111-3 and 122-3 and the outer contour extension directions of the second segments 111-2 and 122-2 means that the extension directions of most of the outer contours of the third segments 111-3 and 122-3 and most of the outer contours of the second segments 111-2 and 122-2 are not in a straight line. It is not required that the junction of the third segments 111-3 and 122-3 and the second segments 111-2 and 122-2 has a sharp angle; on the contrary, the junction can be smooth.

[0065] In the above description, reference numerals 111 for the first cantilever and 122 for the second cantilever are used to represent the three segments of the first and second cantilever, which is only for illustrative purposes in conjunction with specific embodiments. In other embodiments, where the first and second cantilever do not have two arms, or have three arms, the configuration of the three segments can be conceived based on the above description.

[0066] In embodiments of this invention, the fastener 100 may further include a first retaining arm 131 and a second retaining arm 132. The first retaining arm 131 extends from the second end 110-2 of the first cantilever 110 in the opposite direction of the second direction (upward as shown) toward the first end 120-1 of the second cantilever 120. The second retaining arm 132 extends from the second end 120-2 of the second cantilever 120 in the opposite direction of the second direction (upward as shown) toward the first end 120-1 of the second cantilever 120. The first retaining arm 131 and the second retaining arm 132 are arranged facing each other.

[0067] In this embodiment, the first retaining arm 131 includes a first retaining end, which includes a first retaining surface 131-1 facing the top 100-T of the fastener 100, capable of providing a reverse support force in the second direction; similarly, the second retaining arm 132 includes a second retaining end, which includes a second retaining surface 132-1 facing the top 100-T of the fastener 100, capable of providing a reverse support force in the second direction. In one embodiment, the first retaining surface 131-1 and the second retaining surface 132-1 are located in the same plane.

[0068] In one embodiment, the first holding arm 131 and the second holding arm 132 face each other, the first holding end and the second holding end face each other, and the first holding surface 131-1 of the first holding end is located on the same plane; that is, when the first holding end and the second holding end jointly hold the object, the first holding surface 131-1 and the second holding surface 132-1 abut against and bear on the surface or wall of the object together, providing support force.

[0069] In another embodiment, such as Figure 3 and Figure 5 As shown, the first holding end of the first holding arm 131 and the second holding end of the second holding arm 132 are offset in the first direction (horizontal direction in the paper); however, the first holding surface 131-1 of the first holding end and the second holding surface 132-1 of the second holding end are still on the same plane.

[0070] In one embodiment, during the insertion of the plate-shaped component 200 into the fastener 100, the plate-shaped component 200 needs to expand the first retaining arm 131 and the second retaining arm 132. The first retaining arm 131 and the second retaining arm 132 undergo elastic deformation, and after the plate-shaped component 200 is inserted for a certain stroke, the first retaining end and the second retaining end can elastically recover and snap into the snap-fit ​​recess 200-2 or snap-fit ​​hole of the plate-shaped component 200. The first retaining surface 131-1 and the second retaining surface 132-1 abut against the wall of the snap-fit ​​recess 200-2 or the snap-fit ​​hole. When the plate-shaped component 200 is withdrawn (opposite to the insertion action), the first retaining surface 131-1 and the second retaining surface 132-1 abut against the wall of the snap-fit ​​recess 200-2 or the snap-fit ​​hole and provide supporting force, preventing the plate-shaped component 200 from being withdrawn, thereby achieving a fastening effect. The configuration of the first retaining surface 131-1 and the second retaining surface 132-1 can provide more stable support and a larger support surface.

[0071] In one embodiment, such as Figure 5As shown, the first retaining arm 131 includes a first limiting portion 131-3, and the second retaining arm 132 includes a second limiting portion 132-3. The first limiting portion 131-3 and the second limiting portion 132-3 are configured to provide a limiting space between the first retaining end and the second retaining end, which can restrict movement. The first limiting portion 131-3 can protrude from the first retaining surface 131-1, and the second limiting portion 132-3 can protrude from the second retaining surface 132-1, thereby providing a limiting space between the first retaining surface 131-1 and the second retaining surface 132-1, and between the opposite sides of the first limiting portion 131-3 and the second limiting portion 132-3. The portion of the plate-shaped member 200 located in the limiting space is limited by the opposite sides of the first limiting portion 131-3 and the second limiting portion 132-3 in the horizontal direction along the figure, and is also limited by the support of the first retaining surface 131-1 and the second retaining surface 132-1. The first limiting part 131-3 and the second limiting part 132-3 are advantageous because by limiting the offset of the plate member 200, the plate member 200 can be prevented from deviating from or even separating from the first retaining surface 131-1 and the second retaining surface 132-1, thereby reducing the risk of the plate member 200 separating.

[0072] In one embodiment, the first retaining arm 131 and the second retaining arm 132 each include a first inclined surface 131-2 and a second inclined surface 132-2, which face each other so that when the plate-shaped member 200 is inserted into the fastener 100, the plate-shaped member 200 separates the first retaining arm 131 and the second retaining arm 132 by abutting against the first inclined surface 131-2 and the second inclined surface 132-2 and sliding on the first inclined surface 131-2 and the second inclined surface 132-2. The first inclined surface 131-2 and the second inclined surface 132-2 are advantageous in that they can reduce the force required to insert the plate-shaped member 200, reduce damage to the plate-shaped member 200, and improve the user experience.

[0073] In this embodiment, the first inclined surface 131-2 extends to the first retaining surface 131-1, and the second inclined surface 132-2 extends to the second retaining surface 132-1, so that the first retaining arm 131 and the second retaining arm 132 are elastically reset after a portion of the plate member 200 passes between the first inclined surface 131-2 and the second inclined surface 132-2.

[0074] In one embodiment of this utility model, for example, Figure 1 and Figure 2 In the illustrated embodiment, the first retaining arm 131 is located between the first cantilever first support arm 111 and the first cantilever second support arm 112, and the second retaining arm 132 is located between the second cantilever first support arm 121 and the second cantilever second support arm 122. In this embodiment, the first retaining arm 131 and the second retaining arm 132 face each other, as shown in the reference. Figure 3 As shown in the figure, the portion of the first retaining arm 131 near the second end 110-2 of the first cantilever 110 and the portion of the second retaining arm 132 near the second end 120-2 of the second cantilever 120 face each other, while the distal portion of the first retaining arm 131 away from the second end 110-2 of the first cantilever 110 and the distal portion of the second retaining arm 132 away from the second cantilever 120-2 are offset from each other. This is advantageous because it allows the distal portions of the first retaining arm 131 (i.e., the portion near the first retaining end) and the distal portions of the second retaining arm 132 (i.e., the portion near the second retaining end) to protrude more toward each other, and the first retaining end and the second retaining end to protrude more toward each other, thereby allowing the first retaining surface 131-1 and the second retaining surface 132-1 to overlap, providing a larger support surface and improving retaining stability.

[0075] In another embodiment, the first retaining arm 131 and the second retaining arm 132 may be symmetrical about a virtual plane along a first direction that exists between the first cantilever 110 and the second cantilever 120. Figure 1 , 2 Unlike the embodiment shown in 3, the first retaining end and the second retaining end are directly opposite each other. In one implementation, the first retaining end and the second retaining end are in contact, thereby connecting the first retaining surface 131-1 and the second retaining surface 132-1.

[0076] According to an embodiment of the present invention, the first retaining arm 131 and the second retaining arm 132 have enlarged bases, that is, portions close to the second ends 120-2 of the first cantilever 110 and the second cantilever 120, which is beneficial to improving the rigidity of the first retaining arm 131 and the second retaining arm 132, increasing the retaining force and service life.

[0077] In one embodiment of the present invention, the fastener 100 further includes a first positioning arm 141 and a second positioning arm 142 extending from the top 100-T of the fastener 100 along a second direction. The first positioning arm 141 and the second positioning arm 142 face each other and respectively provide at least one first positioning fulcrum and a second positioning fulcrum for positioning the plate-shaped member 200 between them. (Refer to...) Figure 4 In one embodiment, the first positioning arm 141 and the second positioning arm 142 extend downward from the top 100-T of the fastener 100, respectively. A first positioning fulcrum and a second positioning fulcrum are provided at the ends of the first positioning arm 141 and the second positioning arm 142, respectively. These are positioning protrusions that extend a certain width along a first direction, thereby improving positioning stability.

[0078] like Figure 4As shown, the ends of the first positioning arm 141 and the second positioning arm 142 respectively include inclined surfaces, which facilitates the insertion of the plate-shaped member 200 between the ends of the first positioning arm 141 and the second positioning arm 142, so that the first positioning fulcrum and the second positioning fulcrum clamp the plate-shaped member 200, providing clamping force from one side of the plate-shaped member 200 and improving the holding stability.

[0079] In this utility model, reference is made to Figure 9 To make it easier to understand, the first positioning arm 141 and the second positioning arm 142 provide clamping force at the end 200-1 of the plate-shaped member 200, and the first holding arm 131 and the second holding arm 132 provide holding or limiting effect on the plate-shaped member 200 near the middle position of the figure. In some implementations, the second ends 120-2 of the first cantilever 110 and the second cantilever 120 provide clamping force at a third position (lower position of the figure) of the plate-shaped member 200 (this will be explained in detail later), thereby achieving clamping of the plate-shaped member 200 at multiple positions and achieving an improved holding effect, so that the fastener 100 will not fall off even if it undergoes large deformation during insertion and removal.

[0080] In one embodiment of the present invention, the second end 110-2 of the first cantilever 110 includes a first guide portion 151, and the second end 120-2 of the second cantilever 120 includes a second guide portion 152. The first guide portion 151 and the second guide portion 152 are configured to facilitate the insertion of the plate-shaped member 200 into the fastener 100. The first guide portion 151 and the second guide portion 152 have an outward "V" profile and have a first protrusion 151-1 and a second protrusion 152-1 that protrude from each other. This arrangement facilitates guiding the end 200-1 of the plate-shaped member 200 into the space between the first guide portion 151 and the second guide portion 152. After the plate-shaped member 200 is inserted, the first protrusion 151-1 and the second protrusion 152-1 of the first guide portion 151 and the second guide portion 152 (as mentioned above, in the third position) clamp the plate-shaped member 200 and provide a clamping force on the surface of the plate-shaped member 200. The first protrusion 151-1 and the second protrusion 152-1 can extend a large width along the first direction, for example, close to the width of the first cantilever 110 and the second cantilever 120, which is advantageous and can further improve the holding stability of the plate member 200.

[0081] In some applications, the mounting hole or opening 300 into which the fastener 100 is inserted is 4cm or 6cm wide, and the width of the fastener 100 (first direction) of this utility model can be close to 4cm or 6cm.

[0082] This utility model provides a fastener assembly, including the fastener 100 described above. In practical applications, the fastener assembly further includes a plate-shaped member 200. For example... Figure 7-9As shown, the plate-shaped member 200 is inserted into the fastener 100. The plate-shaped member 200, with the fastener 100 installed, can be easily inserted into a mounting hole or opening 300 in the base plate 1000, such as a mounting hole or opening 300 on the interior surface of an automobile. This allows the fastener 100 to secure a part with the plate-shaped member 200 (e.g., a trim panel) or parts connected to the plate-shaped member 200 to the base plate 1000 (e.g., an interior surface of an automobile). One application of this is mounting a trim panel to the surface of the vehicle body, requiring only a mounting hole or opening 300 on the body surface to easily fix the trim panel with the fastener 100 to the body surface. Here, the plate-shaped member 200 can have, for example... Figure 7-8 The shape shown in 10 can also have other shapes. Figure 10 The plate-shaped member 200 has ridges 203 on both sides, which can improve the rigidity and strength of the plate-shaped member 200; in other embodiments, the plate-shaped member 200 does not have ridges 203. Figure 10 The plate-shaped member 200 has a snap-fit ​​opening. After the first retaining end and the second retaining end elastically recover, they snap into the snap-fit ​​opening so that the first retaining surface 131-1 and the second retaining surface 132-1 abut against the snap-fit ​​recess 200-2 or the wall of the snap-fit ​​opening, such as the upper wall of the snap-fit ​​opening in the figure. However, the plate-shaped member 200 may be in the form of having a snap-fit ​​recess 200-2 (i.e., not through the plate-shaped member 200).

[0083] Figure 7 The diagram shows a part with fastener 100 fixed in a mounting hole or opening 300 on a base plate 1000 (e.g., the surface of a vehicle body). When the part needs to be removed, it is pulled out directly. During the removal process, the upper wall of the snap-fit ​​recess 200-2 of the plate-shaped part 200 abuts against the first retaining surface 131-1 and the second retaining surface 132-1, causing the fastener 100 and the plate-shaped part 200 to be pulled out together. As a result, the second sections of the first cantilever 110 and the second cantilever 120 of the fastener 100 are squeezed by the edge of the mounting hole or opening 300 of the base plate 1000. The first cantilever 110 (first support arm and second support arm) and the second cantilever 120 (first support arm and second support arm) undergo elastic deformation and are flattened, thereby the fastener 100 is pulled out from the mounting hole or opening 300 of the base plate 1000. During this process, the first retaining surface 131-1 and the second retaining surface 132-1 of the fastener 100 abut against the upper wall of the snap-fit ​​recess 200-2 of the plate-shaped part 200, the second end 120-2 of the first cantilever 110 and the second cantilever 120 of the fastener 100 clamps the plate-shaped part 200, and the first positioning arm 141 and the second positioning arm 142 of the fastener 100 hold the end 200-1 of the plate-shaped part 200. During the insertion and removal of the plate-shaped part 200, the fastener 100 can be fastened to the plate-shaped part 200.

[0084] The fastener assembly of this utility model is reusable, easy to insert and remove, and improves the user experience. The fastener 100 of this utility model can be easily installed on parts or other components, and can be easily inserted into the mounting hole or opening 300 and removed, improving the installation and disassembly of parts or components. It is also reusable, combining a good user experience and durability.

[0085] The fastener of this invention has low requirements for the plate-shaped part 200 on which the fastener is installed, thus reducing the manufacturing difficulty and cost.

[0086] One embodiment of this utility model provides a fastener 100. Figure 11 Its front view is shown. In this embodiment, it is related to... Figure 1-3 The illustrated embodiment differs in that the first and second directions are not orthogonal. Figure 3 In the fastener 100, the top of the fastener 100 in the first (width) direction is perpendicular to both the first cantilever 110 and the second cantilever 120 of the fastener 100. However, in this embodiment, both the first cantilever 110 and the second cantilever 120 of the fastener 100 extend from the top 100-T of the fastener 100 along a second direction, and the second direction forms an angle with the first direction other than 90 degrees, such as 85 degrees, 80 degrees, 75 degrees, 70 degrees, etc., and the specific angle can be set as needed. In this embodiment, since the first cantilever 110 and the second cantilever 120 are inclined relative to the top 100-T of the fastener 100, the fastener 100 can be inserted into the mounting hole or opening 300 of the substrate 1000 along the inclined direction, thereby installing parts with plate-shaped members 200 (such as decorative panels) or parts connected to plate-shaped members 200 along the inclined direction with the substrate 1000, improving the adaptability of the fastener 100, for example, allowing decorative parts or parts to be installed at deformed locations.
