Description

Technical Field

[0001] The present invention relates to a snap structure for achieving assembly and fixation between two components. Background Art

[0002] In the prior art, in order to assemble automotive exterior parts to a vehicle, a snap structure needs to be provided between the vehicle body and the automotive exterior parts. Regarding the snap structure, in addition to the commonly used doghouse structure, there are also, for example, gantry integrated plastic snaps and techniques using adhesion for fixation in the prior art.

[0003] However, the prior art has the following problems: The doghouse structure has a large volume and a complex structure, the injection molding process during manufacturing is complex, and the doghouse structure cannot be arranged at the tip position of components; the snap part of the gantry integrated plastic snap is prone to breakage; when using adhesion for fixation, the viscosity of double-sided tape and the like decreases over time, so good fixation cannot be achieved either. Summary of the Invention

[0004] An object of the present invention is to provide a snap structure that is simple in structure and durable.

[0005] The present invention provides a snap structure, comprising:

[0006] A main body part, the main body part being a plate-shaped part protruding from an assembled component, having end parts located at both ends in the length direction and an intermediate part located between the two end parts, and the intermediate part deviating from the straight line where the two end parts are located in the width direction;

[0007] A protrusion part, the protrusion part protruding from the main body part toward the outside in the width direction, and a surface of the protrusion part on the side away from the assembled component being an inclined surface with a protrusion height that protrudes from the main body part and increases as it gets closer to the assembled component; and

[0008] A locking hole, the locking hole being provided in a plate-shaped assembling component and capable of allowing the main body part and the protrusion part to be inserted therethrough,

[0009] The main body part is made of a material that can be elastically deformed, and can be elastically deformed in such a way that the intermediate part approaches the straight line in the width direction.

[0010] The snap structure of the present invention is provided with an arch-shaped main body part and a protrusion part protruding from the main body part, so that when locking, the main body part itself undergoes elastic deformation. Therefore, the snap structure of the present invention has a simple structure, a small volume, and the connection between the main body part and the protrusion part is not prone to breakage.

[0011] In the above snap structure, preferably,

[0012] The surface of the protruding portion on the side close to the component to be assembled is a locking inclined surface that is farther away from the component to be assembled as the protruding height from the main body portion increases.

[0013] That is, by providing the locking inclined surface, the width of the main body portion can be reduced by applying a force in the height direction, thereby releasing the assembly fixation between the assembly component and the component to be assembled. The operation is simple and it can be reused.

[0014] In the above snap structure, preferably,

[0015] The width of the main body portion is equal to the width of the locking hole. After the main body portion is completely inserted into the locking hole, the two ends and the middle part of the main body portion are respectively in contact with the inner surfaces on both sides in the width direction of the locking hole.

[0016] Thus, after the locking is completed, the main body portion can also be positioned in the width direction through the locking hole.

[0017] In the above snap structure, preferably,

[0018] The main body portion is in the shape of an arc-shaped plate or an arch-shaped plate formed by connecting a plurality of straight plates.

[0019] Thus, the snap structure can be formed using a simple mold.

[0020] In the above snap structure, preferably,

[0021] The protruding portion protrudes from the middle portion of the main body portion in the width direction toward the direction away from the straight line.

[0022] Thus, the middle portion of the main body portion can be deformed by applying a force in the height direction to approach the straight line where the end portions are located.

[0023] In the above snap structure, preferably,

[0024] The protruding portion protrudes from at least one of the two end portions of the main body portion in the width direction toward the direction away from the middle portion.

[0025] Thus, the middle portion of the main body portion can be deformed by applying a force in the height direction to approach the straight line where the end portions are located.

[0026] In the above snap structure, preferably,

[0027] The main body portion is provided with a guiding end portion at the end away from the component to be assembled. In the guiding end portion, the plate thickness is thinner as it is farther away from the component to be assembled.

[0028] Thus, by providing the guiding end portion, when the main body portion is initially inserted into the locking hole, the guiding end portion can play a guiding role, making it easier to insert the main body portion.

[0029] In the above snap structure, preferably,

[0030] The protruding portion protrudes from the main body portion at a position closer to the component to be assembled than the guiding end portion.

[0031] Thus, the guiding end portion with a relatively thin plate thickness can better play a guiding role without being interfered by the protruding portion.

[0032] In the above snap structure, preferably,

[0033] The end of the protruding portion away from the component to be assembled is flush with the end of the main body portion away from the component to be assembled.

[0034] Thus, the guiding role can be achieved by using the inclined surface of the protruding portion.

[0035] In the above snap structure, preferably,

[0036] A sheet-shaped sound-absorbing and shock-absorbing material is provided on the surface of the component to be assembled on the side where the main body portion is provided.

[0037] Thus, it is possible to reduce the noise during the assembly and locking process and avoid damage to the structure caused by vibration. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The following describes exemplary embodiments of the present invention with reference to the accompanying drawings. Various details of the embodiments of the present invention are included to facilitate understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, descriptions of well-known functions and structures are omitted in the following description for clarity and conciseness.

[0047] It should be noted that, without conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0048] The snap structure 1 of the present invention is used to assemble and fix the component to be assembled 5 to the assembly component 6. In the following description of this specification, the body component is used as the assembly component 6, and the vehicle interior and exterior trim panels are used as the component to be assembled 5. That is, the snap structure 1 of the present invention can be used to assemble and fix the vehicle interior and exterior trim panels to the body component. However, the snap structure 1 can of course also be used to assemble and fix other components. That is, the assembly component 6 can be a component other than the body component, and the component to be assembled 5 can be a component other than the vehicle interior and exterior trim panels.

[0049] In the following description, the length direction YC represents the length direction of the main body portion 2 and the locking hole 4, which is the direction in which the two end portions 2a of the main body portion 2 are arranged side by side, and is the direction in which the straight line 2c described later extends; the width direction XC represents the width direction of the main body portion 2 and the locking hole 4, which is the direction in which the intermediate portion 2b in the main body portion 2 deviates from the straight line 2c, and is the direction in which the two inner surfaces 41, 42 of the locking hole 4 face each other; the height direction ZC is the height direction of the main body portion 2, and is the plate thickness direction of the assembly component 6, and is parallel to the direction in which the main body portion 2 protrudes from the component to be assembled 5.

[0050] In addition, the inner side in the width direction refers to the direction from the end portions 2a, 2b to the midpoint of the end portion 2a and the intermediate portion 2b in the width direction XC; the outer side in the width direction refers to the direction from the end portions 2a, 2b to the side opposite to the midpoint of the end portion 2a and the intermediate portion 2b in the width direction. That is, the outer side in the width direction refers to the direction away from the main body portion 2 in the width direction. For the intermediate portion 2b, the outer side in the width direction refers to the direction away from the straight line 2c (end portion 2a), and for the end portion 2a, the outer side in the width direction refers to the direction away from the intermediate portion 2b.

[0051] In addition, the "width of the main body portion 2" refers to the distance between the intermediate portion 2b and the end portion 2a (straight line 2c) in the width direction.

[0052] As Figures 1 to 3As shown, the snap structure 1 of the present invention includes a main body portion 2 provided on the component to be assembled 5 and a locking hole 4 provided on the assembling component 6. A protrusion portion 3 is provided on the main body portion 2. When assembling and fixing the component to be assembled 5 to the assembling component 6, as Figure 1 and Figure 6 shown, the main body portion 2 is inserted through the locking hole 4, and the plate-shaped assembling component 6 is clamped between the protrusion portion 3 and the component to be assembled 5 (the foam 7 described later), thereby realizing the assembly and fixation of the assembling component 6 and the component to be assembled 5.

[0053] The specific structures of the main body portion 2, the protrusion portion 3, and the locking hole 4 will be described below.

[0054] <Main body portion 2>

[0055] As Figure 2 and Figure 3 shown, the main body portion 2 protrudes from the component to be assembled 5, and is, for example, a plate shape protruding from the component to be assembled 5 in the direction perpendicular to the surface of the component to be assembled 5, that is, the height direction ZC.

[0056] As Figure 5 shown, the main body portion 2 has end portions 2a located at both ends in the length direction YC and an intermediate portion 2b located between the two end portions 2a. The intermediate portion 2b deviates from the straight line 2c where the two end portions 2a are located in the width direction. That is, the main body portion 2 is not a straight plate shape, but an arched plate shape convex toward one side in the width direction XC.

[0057] The main body portion 2 is formed of a material that can be elastically deformed. When the component to be assembled 5 is an interior or exterior vehicle trim part, the main body portion 5 can be made of the same material as the component to be assembled 5, for example, made of common plastic materials such as PC + ABS, PC + PET, ASA, PC, PP, etc., so that the main body portion 2 can achieve a certain degree of elastic deformation.

[0058] For example, as Figure 5 shown, the main body portion 2 can be elastically deformed in such a way that the intermediate portion 2c approaches the straight line 2c where the two end portions 2a are located in the width direction, that is, the main body portion 2 can be elastically deformed in such a way that the width (the distance between the intermediate portion 2b and the end portion 2a (straight line 2c) in the width direction) becomes smaller.

[0059] <Protrusion portion 3>

[0060] The protrusion portion 3 protrudes from the main body portion 2 in the width direction XC toward the outside in the width direction. Specifically, in this embodiment, the protrusion portion 3 protrudes from the intermediate portion 2b of the main body portion 2 in the width direction XC toward the direction away from the end portion 2a (straight line 2c).

[0061] As Figure 6As shown, since the locking is achieved by the protrusion 3 of the buckle structure 1 and the peripheral edge of the locking hole 4 of the assembled component 6 being clamped by the assembled component 5, the distance of the protrusion 3 from the root of the main body portion 2, that is, the distance from the surface of the assembled component 5 (or the foam 7), should be equal to the plate thickness of the assembled component 6 at the peripheral edge of the locking hole 4.

[0062] In order to enable the protrusion 3 to be inserted into the locking hole 4, the surface of the protrusion 3 on the side away from the assembled component 5 (i.e., the surface that contacts the peripheral edge of the locking hole 4 during the insertion process) is set as an inclined surface 31, and the higher the protrusion height from the main body portion 2 is as the inclined surface 31 is closer to the assembled component 5. Thus, when the protrusion 3 and the main body portion 2 are inserted into the locking portion 4 together, the inclined surface 31 of the protrusion 3 can convert the force applied by the operator in the protruding direction of the main body portion 2 (along the height direction ZC) into a force along the width direction XC, so that the main body portion 2 undergoes elastic deformation with the intermediate portion 2b approaching the straight line 2c by using the force along the width direction XC.

[0063] <Locking hole 4>

[0064] As Figure 4 shown, the locking hole 4 is a through hole provided in the plate-shaped assembled component 6. Here, the locking hole 4 can be set as a long rectangular shape, and the width in the width direction XC is smaller than the total width of the main body portion 2 and the protrusion 3, so that when the protrusion 3 and the main body portion 2 are inserted into the locking hole 4 together, the intermediate portion 2b of the main body portion 2 can approach the straight line 2c and undergo elastic deformation.

[0065] As long as the above deformation can occur, the locking hole 4 can also be other shapes. For example, the locking hole 4 can also be a long arched shape.

[0066] In addition, in order to enable the protrusion 3 to pass through the locking hole 4, the width of the locking hole 4 should be greater than or equal to the total measurement of the width of the main body portion 2 after elastic deformation and the width of the protrusion 3 (the protrusion height in the width direction), so that the locking hole 4 can allow the main body portion 2 and the protrusion 3 to be inserted through.

[0067] <Assembly process>

[0068] When assembling and fixing the assembled component 5 to the assembled component 6, first insert the end of the main body portion 2 (the end away from the assembled component 5 in the height direction ZC) into the locking hole 4 of the assembled component 6. As Figure 3 shown, as the insertion progresses, the protrusion 3 will gradually be inserted into the locking hole 4 together with the main body portion 2.

[0069] When the protrusion 3 and the main body portion 2 are inserted into the locking hole 4 together, as Figure 5As shown, one inner surface 42 in the width direction of the locking hole 4 contacts the inclined surface 31 of the protrusion 3 and presses the inclined surface 31 in the width direction, applying a force F1 in the width direction XC to the inclined surface 31.

[0070] Due to this force F1 in the width direction XC, the other inner surface 41 on the other side of the locking hole 4 in the width direction XC applies a force F2 in the width direction XC to both ends 2a of the main body 2 respectively. Both the force F1 and the force F2 are forces towards the inner side in the width direction, that is, the force F1 is a force in the width direction XC from the protrusion 3 (the middle part 2b) towards the straight line 2c (the end 2a), and the force F2 is a force in the width direction XC from the end 2a towards the middle part 2b. Due to the action of the force F1 and the force F2, as Figure 5 shown by the yellow dashed line in the figure, the main body 2 deforms in such a way that the middle part 2b approaches the straight line 2c in the width direction (that is, the width of the main body 2 becomes smaller).

[0071] As the insertion depth of the protrusion 3 increases, the degree of deformation of the main body 2 will increase accordingly, the middle part 2b further approaches the straight line 2c, and the width of the main body 2 further becomes smaller.

[0072] When the protrusion 3 completely passes through the locking hole 4, as Figure 1 and Figure 6 shown, the deformation of the main body 2 is eliminated and it returns to its original state, and the protrusion 3 is locked to the periphery of the locking hole 4 of the assembled component 6, thereby assembling and fixing the component 5 to be assembled to the assembled component 6.

[0073] As described above, the snap structure 1 of the present invention is provided with an arch-shaped main body 2 and a protrusion 3 protruding from the main body 2, so that when locking is performed, the main body 2 itself undergoes elastic deformation. Therefore, the structure of the snap structure 1 of the present invention is simple, has a small volume, and the connection between the main body 2 and the protrusion 3 is not easily broken.

[0074] In addition, in this embodiment, as Figure 6 shown, the surface of the protrusion 3 on the side close to the component 5 to be assembled is a locking inclined surface 32, and this locking inclined surface 32 is an inclined surface that is farther away from the component 5 to be assembled as the protrusion height protruding from the main body 2 increases.

[0075] Thus, when it is necessary to release the assembly and fixation between the assembled component 6 and the component 5 to be assembled, only a force for separating in the height direction ZC needs to be applied to the component 5 to be assembled and the assembled component 6, so that this force acts on the locking inclined surface 32 and the periphery of the locking hole 4 of the assembled component 6, and this force will be converted into a force along the width direction XC that reduces the width of the main body 2 via this locking inclined surface 32.

[0076] That is, by providing the locking inclined surface 32, a force in the inner side in the width direction can be applied to the protrusion 3 by applying a force in the height direction ZC, so that the middle portion 2b deforms toward the straight line 2c, and the width of the main body portion 2 is reduced to release the assembled fixing of the assembled component 6 and the component to be assembled 5. The operation is simple and it can be reused.

[0077] In addition, in the above embodiment, as Figure 6 shown, the width of the main body portion 2 locked in the locking hole 4 is equal to the width of the locking hole 4.

[0078] Thus, after the locking is completed, the main body portion 2 is completely inserted into the locking hole 4, and both sides in the width direction of the main body portion 2 (the middle portion 2b and the two end portions 2a) are respectively in contact with the two inner surfaces 41, 42 of the locking hole 4. Therefore, after the locking is completed, the main body portion 2 can also be positioned in the width direction through the locking hole 4.

[0079] However, the main body portion 2 may also be shaped such that its width is slightly larger than the width of the locking hole 4 in the free state. Thus, even when the main body portion 2 is completely inserted into the locking hole 4 and the protrusion 3 is locked to the periphery of the locking hole 4, the deformation of the main body portion 2 is not completely released. Even in this state, the width of the main body portion 2 locked in the locking hole 4 can be made equal to the width of the locking hole 4.

[0080] In addition, in the above embodiments, as Figures 1 to 5 shown, the main body portion 2 is in the shape of an arc-shaped plate. However, as long as the main body portion 2 has end portions 2a located at both ends in the length direction and a middle portion 2b located between the two end portions 2a, and the middle portion 2b deviates from the straight line 2c where the two end portions 2a are located in the width direction XC, the main body portion 2 can also be of other shapes. For example, in addition to being an arc-shaped plate, the main body portion 2 can also be an arch-shaped plate formed by connecting a plurality of straight plates.

[0081] In particular, when the main body portion 2 is an arch-shaped plate formed by connecting a plurality of straight plates, the main body portion 2 can even be a plate with a trapezoidal cross-section (formed by connecting three straight plates) or a plate with a triangular cross-section (formed by connecting two straight plates). When the main body portion 2 is a plate with a trapezoidal cross-section, it includes a top plate and side plates extending from both sides of the top plate. At this time, the top plate forms the middle portion 2b, and the free ends of the side plates form the end portions 2a; when the main body portion 2 is an arch-shaped plate with a triangular cross-section, it includes two side plates, and one end of the two side plates is connected to each other and the other end is a free end. At this time, the connected end of the two side plates is the middle portion 2b, and the free ends of the two side plates are the end portions 2a.

[0082] In the above cases, the main body portion 2 can be deformed in such a way that the middle portion 2b approaches the straight line 2c where the two end portions 2a are located in the width direction, and when the main body portion 2 is an arched plate formed by connecting a plurality of straight plates, the structure of the mold is simpler.

[0083] In addition, in the above embodiments, the protrusion portion 3 protrudes from the middle portion 2b of the main body portion 2 in the width direction XC away from the straight line 2c, but the protrusion portion 3 can also be provided at the end portion 2a. For example, the protrusion portion 3 can also protrude from the two end portions 2a in the width direction XC away from the middle portion 2b (outer side in the width direction).

[0084] However, the protrusion portion 3 can also protrude from one end portion 2a in the width direction XC away from the middle portion 2b, so that the forming mold is simpler and the structure of the protrusion portion 3 is also simpler.

[0085] It should be noted that in this embodiment, the protrusion portion 3 can be formed by using a small lifter in the mold, and this will not be elaborated here.

[0086] In addition, in the above embodiments, as Figures 1 to 3 shown, a guiding end portion 21 is provided at the end of the main body portion 2 away from the assembled component 5. In the guiding end portion 21, the closer to the end of the main body portion 2 (i.e., the farther from the assembled component 5), the thinner the plate thickness of the guiding end portion 21.

[0087] Thus, by providing the guiding end portion 21, when the main body portion 2 is initially inserted into the locking hole 4, the guiding end portion 21 can play a guiding role, so that the main body portion 2 is easily inserted.

[0088] In the case where the guiding end portion 21 is provided, the protrusion portion 3 is preferably provided to protrude from a portion of the main body portion 2 other than the guiding end portion 21, that is, the protrusion portion 3 protrudes from the main body portion 2 at a position closer to the assembled component 5 than the guiding end portion 21. Thus, the guiding role of the guiding end portion 21 with a thinner plate thickness can be better exerted.

[0089] However, the end of the protrusion portion 3 away from the assembled component 5 can also be flush with the end of the main body portion 2 away from the assembled component 5. At this time, when the main body portion 2 is initially inserted into the locking hole 4, the protrusion portion 3 is inserted into the locking hole 4 together with the main body portion 2, so that the guiding role can be achieved by using the inclined surface 31 of the protrusion portion 3.

[0090] In addition, when the guiding end portion 21 is provided, the end portion of the protruding portion 3 away from the component to be assembled 5 can be flush with the end of the main body portion 2 away from the component to be assembled 5. When the guiding end portion 21 is not provided, the end portion of the protruding portion 3 away from the component to be assembled 5 can also be flush with the end of the main body portion 2 away from the component to be assembled 5. Whether the guiding end portion 21 is provided or not, when the end portion of the protruding portion 3 away from the component to be assembled 5 is flush with the end of the main body portion 2 away from the component to be assembled 5, the guiding function during insertion can be achieved by means of the inclined surface 31 of the protruding portion 3.

[0091] In addition, in the above description, it is described that as Figure 6 shown, a foam 7 is provided on the surface of the component to be assembled 5 to achieve sound absorption and shock absorption during locking. However, the foam may not be provided, or other sheet-shaped sound absorption and shock absorption materials such as rubber may be provided.

[0092] The foam 7 is provided with holes of the same size as the locking holes 4, for example, and is adhesively provided on the component to be assembled 5 in such a way that the main body portion 2 passes through the holes, so as to provide buffering when the assembled component 6 is locked between the protruding portion 3 and the component to be assembled 5, and achieve the effects of sound absorption and shock absorption.

[0093] <Comparative Example 1>

[0094] As Comparative Example 1, for example, as Figure 7 shown, the snap structure 1A of Comparative Example 1 includes a main body portion 2A protruding from a component to be assembled (not shown), and the main body portion 2A is in a straight plate shape. The snap structure 1A is further provided with a protruding portion 3A that can elastically deform relative to the main body portion 2A, and the protruding portion 3A can elastically deform between a state of protruding from the main body portion 2A and a state of retracting into the interior of the main body portion 2A.

[0095] When inserting the main body portion 2A and the protruding portion 3A into the locking hole 4A of the assembled component 6A, the main body portion 2A does not elastically deform, but the protruding portion 3A elastically deforms. Specifically, when the main body portion 2A and the protruding portion 3A are inserted into the locking hole 4A, since the side wall of the locking hole 4A exerts a squeezing force on the protruding portion 3A, the protruding portion 3A elastically deforms and swings about the X portion (the connecting portion of the protruding portion 3A and the main body portion 2A) in the figure, so as to retract from the state of protruding from the main body portion 2A into the main body portion 2A. When the protruding portion 3A completely passes through the locking hole 4A, the protruding portion 3A returns to its original state and returns to the state of protruding from the main body portion 2A. At this time, as Figure 7 shown, the protruding portion 3A is locked to the periphery of the locking hole 4A, thereby assembling and fixing the assembled component 6A and the component to be assembled (not shown).

[0096] However, such a locking mechanism 1A is relatively weak at the connection part X between the main body part 2A and the protruding part 3A, and the connection part X often deforms, so it is prone to fracture and breakage when stressed.

[0097] In contrast, in the snap structure 1 of the present invention, when locking is performed, it is the main body part 2 itself that deforms, and the connection part between the protruding part 3A and the main body part 3 does not deform. Therefore, the snap structure 1 of the present invention is not prone to breakage and other damages.

[0098] <Comparative Example 2>

[0099] As Figure 8 shown, there is also an encapsulation nail in the prior art, which includes a press nail 1B and a press cover 2B. The press nail 1B is composed of a press cap 101B and a bolt rod 102B. The bolt rod 102B is provided with a through deformation groove 104B, and snap fasteners 105B are arranged on both sides of the bolt rod 102B located at the deformation groove 104B.

[0100] When the press nail 1B and the press cover 2B are used, the press cover 2B is pressed onto the bolt rod 102B of the press nail 1B, so that the hole 201B of the press cover 2B contacts the snap fastener 105B at the end of the bolt rod 102B. Since the snap fastener 105B is trapezoidally arranged, the inclined surface thereof receives the extrusion force of the press cover 2B, deforming the end of the bolt rod 102B, so that the bolt rod 102B penetrates into the hole 201B until the snap fastener 105B passes through the hole 201B, and the snap fastener 105B snaps the press cover 2B on the surface of the bolt rod 102B.

[0101] Although the parts on both sides of the deformation groove 104B of the bolt rod 102B in the comparative example are also in the shape of an arc-shaped plate (arch-shaped plate) like the main body part 2 of the present invention, with two end parts and a middle part and the middle part deviating from the straight line where the two end parts are located, however, when locking is performed using the press nail 1B and the press cover 2B, the parts on both sides of the deformation groove 104B of the bolt rod 102B do not elastically deform in a way that the middle part approaches the straight line where the two end parts are located, but deform in a way that the whole tilts towards the deformation groove 104B.

[0102] That is to say, the press nail 1B in Comparative Example 2 must include the deformation groove 104B and the parts on both sides of the deformation groove 104B to achieve locking. When locking, the parts on both sides of the deformation groove 104B of the bolt rod 102B tilt and deform towards the deformation groove 104B with the root as the axis. Compared with the snap structure 1 of the present invention, its composition structure is more complex, so the cost is higher and the occupied space is also larger.

[0103] The above specific embodiments do not constitute a limitation on the protection scope of the present invention. Those skilled in the art should understand that various modifications, combinations, sub - combinations and substitutions can occur depending on design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
