Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a snap-fit ​​structure and a vehicle. Background Technology

[0002] Snap-fit ​​structures, which enable quick connection and fixation between components without the need for additional fasteners, are widely used in many fields such as machinery manufacturing, electronic equipment, automotive industry, and furniture assembly due to their advantages of convenient operation, high assembly efficiency, and low cost. For example, in the installation of automotive interior parts, snap-fit ​​structures are often used to connect trim panels, brackets, and other components, effectively simplifying the assembly process.

[0003] Currently, common snap-fit ​​structures typically consist of two mating snap-fit ​​components. One component has snap-fit ​​parts such as hooks and slots, while the other component has a corresponding snap-fit ​​part. Some structures also include elastic limiting components to enhance stability after snap-fitting. During assembly, the snap-fit ​​parts of the two components engage with each other, and the elastic limiting component provides resistance, thus achieving relative fixation between them.

[0004] However, existing snap-fit ​​structures typically rely solely on their own elasticity for engagement, resulting in limited resistance. When the snap-fit ​​structure is subjected to vibration (such as the connection of components during vehicle operation) or external forces such as accidental collisions or pulling, the resistance of the elastic limiting components is insufficient to effectively resist the tendency of the snap-fit ​​parts to separate. This can easily lead to loosening or even separation of the snap-fit ​​parts, affecting the overall structural stability and potentially causing equipment malfunction or component damage in severe cases. Summary of the Invention

[0005] In order to solve the technical problem that the two interlocking parts of the snap-fit ​​structure may become loose or even detach due to insufficient abutment force of the elastic limiting part, this application provides a snap-fit ​​structure and a vehicle.

[0006] The first aspect of this application provides a snap-fit ​​structure, including: The first card connector has a first card receiving portion; The second snap-fit ​​member includes a body portion and an elastic limiting portion connected to the body portion. A snap-fit ​​channel is formed between the elastic limiting portion and the body portion. The body portion is provided with a second snap-fit ​​portion, which is configured to snap into the first snap-fit ​​portion when the first snap-fit ​​member passes through the snap-fit ​​channel. The elastic limiting portion abuts against the first snap-fit ​​member by its own elastic force to prevent the first snap-fit ​​portion and the second snap-fit ​​portion from disengaging. At least one side of the elastic limiting portion is connected to the body portion by a reinforcing structure, which is configured to increase the abutting force of the elastic limiting portion against the first snap-fit ​​member.

[0007] In some embodiments, a mounting groove is provided on the side wall of the main body, and one end of the elastic limiting part is connected to the first groove wall of the mounting groove.

[0008] In some embodiments, the mounting groove includes a second groove wall connected to both sides of the first groove wall, and the reinforcing structure is connected between the elastic limiting portion and the second groove wall.

[0009] In some embodiments, the body portion, the elastic limiting portion, and the reinforcing structure are integrally formed.

[0010] In some embodiments, the reinforcing structure is a reinforcing plate, and the thickness of the reinforcing plate is less than the thickness of the elastic limiting portion.

[0011] In some embodiments, the end face of the body portion forms a second snap-fit ​​portion, and the first snap-fit ​​portion is configured as a first protrusion disposed on the side of the first snap-fit ​​member opposite to the elastic limiting portion, the first protrusion passing through the snap-fit ​​channel and snapping onto the end face of the body portion.

[0012] In some embodiments, an abutment portion is provided at one end of the elastic limiting portion away from the first groove wall, the abutment portion being used to abut against the first snap-fit ​​member.

[0013] In some embodiments, the elastic limiting portion has a second protrusion on the surface facing the first snap-fit ​​member, and the second protrusion forms the abutment portion.

[0014] A second aspect of this application is a vehicle comprising a snap-fit ​​structure as described in any of the preceding claims.

[0015] In some embodiments, the vehicle further includes a bumper and a trim piece, one of which is provided with the first snap-fit ​​member and the other with the second snap-fit ​​member.

[0016] The technical solution provided in this application has the following advantages compared with the prior art: The snap-fit ​​structure provided in this application embodiment includes a first snap-fit ​​member inserted into the snap-fit ​​channel of a second snap-fit ​​member. The first and second snap-fit ​​portions achieve a snap-fit ​​engagement. An elastic limiting portion abuts against the first snap-fit ​​member through its own elasticity, preventing the first and second snap-fit ​​portions from separating. A reinforcing structure connects the elastic limiting portion and the main body, increasing the abutting force of the elastic limiting portion on the first snap-fit ​​member, thus ensuring a stable snap-fit ​​between the first and second snap-fit ​​portions. In this snap-fit ​​structure, when the first snap-fit ​​member passes through the snap-fit ​​channel, the second snap-fit ​​portion snaps against the first snap-fit ​​portion, while the elastic limiting portion abuts against the first snap-fit ​​member, forming a double fixing effect. This effectively enhances the stability of the snap-fit ​​structure and reduces the risk of functional failure due to loosening or displacement. The reinforcing structure increases the abutting force of the elastic limiting portion against the first snap-fit ​​member, providing additional support when the elastic limiting portion tends to separate under force. The required abutting force can be increased according to the usage scenario to prevent the first and second snap-fit ​​portions from easily separating. Strengthening the connection between the elastic limiting part and the main body can, to a certain extent, reduce the excessive deformation of the elastic limiting part caused by frequent deformation or large external forces, extend its elastic life, maintain the stable performance of the elastic limiting part, and ensure the long-term reliable operation of the snap-fit ​​structure.

[0021] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0023] In existing snap-fit ​​structures, the elastic limiting components, after prolonged use, are prone to gradual loss of elasticity due to frequent deformation and material fatigue, reducing their resistance to the snap-fit ​​parts. Simultaneously, the connection between the elastic limiting component and the corresponding body part is typically weak, making it susceptible to stress concentration during stress application. This can not only exacerbate the deformation of the elastic limiting component but also lead to loosening of the connection with the body part, preventing it from reliably fulfilling its limiting function, thus shortening the lifespan of the snap-fit ​​structure and increasing maintenance costs.

[0024] Typically, to enhance the strength of the elastic retaining part, the most common solution is to thicken it. However, if the elastic retaining part is thickened excessively, shrinkage marks will appear on the outer surface of the snap-fit ​​due to the internal stress during material injection molding and cooling, resulting in an appearance of dents. When the retaining force of the elastic retaining part is insufficient, and it is impossible to increase the retaining force by thickening the elastic retaining part, the two mating snap-fit ​​parts are prone to detachment, leading to snap-fit ​​failure.

[0025] To address the problem of snap-fit ​​failure in snap-fit ​​structures, this application provides a snap-fit ​​structure that increases the abutting force of the elastic limiting part by setting a reinforcing structure, thereby preventing the first snap-fit ​​member and the second snap-fit ​​member from separating and enhancing the snap-fit ​​effect.

[0026] Specifically, such as Figure 1 The present application provides a snap-fit ​​structure, including a first snap-fit ​​member 1 and a second snap-fit ​​member 2 that cooperate with each other. The first snap-fit ​​member 1 is provided with a first snap-fit ​​portion 11. The second snap-fit ​​member 2 includes a body portion 21 and an elastic limiting portion 22 connected to the body portion 21. A snap-fit ​​channel is formed between the elastic limiting portion 22 and the body portion 21. The first snap-fit ​​member 1 passes through the snap-fit ​​channel, and the body portion 21 is provided with a second snap-fit ​​portion 211. When the first snap-fit ​​member 1 passes through the snap-fit ​​channel, the second snap-fit ​​portion 211 engages with the first snap-fit ​​portion 11.

[0027] Understandably, when the first latching member 1 and the second latching member 2 engage, the first latching member 1 passes through the latching channel from back to front. The engagement of the second latching part 211 with the first latching part 11 restricts the rearward movement of the first latching member 1. The elastic limiting part 22 is made of plastic or metal and can undergo a certain degree of elastic deformation under external force. For example, when the elastic limiting part 22 is bent, it can deform away from the main body part 21, increasing the distance between the elastic limiting part 22 and the main body part 21. When the external force disappears, the elastic limiting part 22 can return to its original position due to its own elasticity. When the first latching member 1 and the second latching member 2 are engaged, as the first latching member 1 passes through the latching channel from back to front, the first latching member 1 squeezes the elastic limiting part 22, causing the elastic limiting part 22 to deform away from the first latching member 1. After the first latching member 1 passes the elastic limiting part 22, the elastic limiting part 22 abuts against the first latching member 1 by its own elasticity.

[0028] After the first snap-fit ​​component 1 and the second snap-fit ​​component 2 are snapped together, the first snap-fit ​​component 1 and the second snap-fit ​​component 211 are snapped together by the first snap-fit ​​part 11 and the second snap-fit ​​part 211. At the same time, the elastic limiting part 22 abuts against the first snap-fit ​​component 1, forming a double fixing effect, which effectively enhances the stability of the snap-fit ​​structure and reduces the risk of functional failure caused by loosening or displacement.

[0029] A reinforcing structure 23 is connected between at least one side of the elastic limiting part 22 and the main body part 21. The reinforcing structure 23 is configured to increase the abutment force of the elastic limiting part 22 against the first latching member 1. The reinforcing structure 23 can provide additional support when the elastic limiting part 22 tends to detach under force, thereby increasing the abutment force of the elastic limiting part 22 and preventing the first latching part 11 from easily detaching from the second latching part 211. The reinforcing structure 23 connects the elastic limiting part 22 and the main body part 21, which can reduce the excessive deformation of the elastic limiting part 22 caused by frequent deformation or large external forces to a certain extent, extend its elastic life, maintain the stable performance of the elastic limiting part 22, and ensure the long-term reliable operation of the latching structure.

[0030] Furthermore, a reinforcing structure 23 is provided on at least one side of the elastic limiting part 22, which will not affect the thickness of the elastic limiting part 22. Therefore, the outer surface of the second snap-fit ​​member 2 will not show shrinkage marks due to the excessive thickness of the elastic limiting part 22. While increasing the abutting force of the elastic limiting part 22, the aesthetics of the second snap-fit ​​member 2 are not affected.

[0031] When the elastic limiting portion 22 is connected to the body portion 21, it forms a cantilever-like structure, that is, one end of the elastic limiting portion 22 is fixed and the other end is a free end. For example, in some embodiments of the present application, a first end of the elastic limiting portion 22 is connected to the body portion 21, and a second end opposite to the first end forms a free end. When cooperating with the first clamping member 1, the second end abuts against the first clamping member 1 by virtue of the elastic force of the elastic limiting portion 22 itself.

[0032] Further, in some embodiments of the present application, the body portion 21 is arranged in an annular shape. It can be understood that the cross-sectional shape of the body portion 21 is rectangle, circle, ellipse or polygon. Taking the rectangular cross-section of the body portion 21 as an example, the body portion 21 includes four side walls, and the four side walls enclose a channel open at both ends, one end of the channel is an inlet end and the other end is an outlet end. The four side walls are a first side wall, a second side wall, a third side wall and a fourth side wall respectively, wherein the first side wall is arranged opposite to the second side wall, and the third side wall is arranged opposite to the fourth side wall. An installation groove communicated with the channel is provided on the first side wall of the body portion 21, a first end of the elastic limiting portion 22 is connected to a first groove wall 212 of the installation groove, and a clamping channel is formed between the elastic limiting portion 22 and the second side wall of the body portion 21. The shape of the installation groove is a square shape or a U-shape. When the installation groove is square-shaped, the installation groove is not communicated with the end faces of the open two ends of the body portion 21. When the installation groove is U-shaped, the notch of the installation groove is opened on the end face of the outlet end of the body portion 21, and the groove bottom is located on the first side wall of the body portion 21.

[0033] For example, in some embodiments of the present application, the shape of the installation groove is U-shaped, the groove bottom of the installation groove is the first groove wall 212 of the installation groove, the two side groove walls of the installation groove are second groove walls 213, and the reinforcing structure 23 is connected between the elastic limiting portion 22 and the second groove walls 213.

[0034] The width of the installation groove is greater than the width of the elastic limiting portion 22. In order to form the cantilever state of the elastic limiting portion 22, gaps are formed between both ends of the elastic limiting portion 22 in the width direction and the two second groove walls 213 of the installation groove, so as to ensure that the second groove walls 213 do not interfere with the elastic limiting portion 22, and the elastic limiting portion 22 can deform in the thickness direction under the action of an external force.

[0035] The existence of the second groove walls 213 provides a more stable and balanced connection point for the reinforcing structure 23. When the reinforcing structure 23 is connected between the elastic limiting portion 22 and the second groove walls 213, it can provide supporting force from both sides of the elastic limiting portion 22 at the same time, increase the strength of the elastic limiting portion 22, and further increase the abutting force exerted by the elastic limiting portion 22 on the first clamping member 1.

[0036] For example, when this snap-fit ​​structure is applied in a vehicle, the two components connected by the snap-fit ​​structure are frequently subjected to vibration during vehicle operation. If the elastic limiting part 22 relies solely on its own unilateral elastic force and its connection with the first groove wall 212 to maintain the abutment force against the first snap-fit ​​member 1, it is prone to shifting due to uneven force under long-term high-frequency vibration, resulting in a decrease in the abutment force and thus loosening of the snap-fit ​​structure. However, through the synergistic effect of the second groove walls 213 on both sides and the reinforcing structure 23, the elastic limiting part 22 can be effectively prevented from tilting to either side, ensuring that it always applies abutment force to the first snap-fit ​​member 1 vertically and stably, greatly improving the reliability of the snap-fit ​​structure in dynamic environments.

[0037] In some embodiments of this application, the main body 21, the elastic limiting part 22, and the reinforcing structure 23 are integrally formed. The three are formed in one step by a mold, without assembly interfaces or adhesive gaps, thus avoiding the problem of "stress concentration at gaps" in separate connections. When the elastic limiting part 22 is deformed by external force, the force can be directly transmitted to the main body 21 through the integral structure, and the reinforcing structure 23 will not fail due to loosening of the interface.

[0038] The second snap-fit ​​component 2 is integrally molded using a mold. Based on the existing mold (which originally could only mold the main body 21 + elastic limiting part 22 + mounting groove, lacking space for the reinforcing structure 23), a groove is cut into the existing mold to create the molding portion for the reinforcing structure 23. The size of the molding portion can be adjusted according to the required strength of the elastic limiting part 22. For example, when the strength of the elastic limiting part 22 needs to be increased, the reinforcing structure 23 needs to be thickened. In this case, the mold can be modified by cutting or grinding away a portion of the structure, thus increasing the thickness of the molding portion and allowing the molten material to fill more space. After molding, the thickness of the reinforcing structure 23 naturally increases. Conversely, if the thickness needs to be reduced, the size of the molding portion can be reduced by welding the mold (partial material replenishment followed by grinding). The mold size adjustment only affects the molding portion of the reinforcing structure 23 and does not change the core dimensions of the main body 21, elastic limiting part 22, and mounting groove. Therefore, the modified mold can still precisely match the original first snap-fit ​​component 1 without adjusting the specifications of other components.

[0039] In some embodiments of this application, the reinforcing structure 23 is a reinforcing plate, and the thickness of the reinforcing plate is less than the thickness of the elastic limiting part 22.

[0040] The reinforcing plate has a planar structure, and its connection with the side wall of the elastic limiting part 22 and the second groove wall 213 is a "surface contact" rather than a point contact or line contact. When the elastic limiting part 22 is deformed by external force, the reinforcing plate can evenly distribute the stress to the second groove wall 213, avoiding cracking of the elastic limiting part 22 or the groove wall due to excessive local stress.

[0041] The reinforcing plate can be fitted to the side of the second groove wall 213 and the elastic limiting part 22 without occupying additional external space of the mounting groove. Especially in "compact space scenarios" such as electronic devices and automotive interiors, it can avoid assembly interference caused by the protrusion of the reinforcing structure 23. At the same time, only a flat groove (forming part) needs to be opened during mold forming, without the need for a complex three-dimensional cavity, reducing the difficulty of mold processing.

[0042] The core function of the elastic limiting part 22 is to generate a resisting force through its own deformation (for example, when the first latching part 1 is inserted, the elastic limiting part 22 needs to deform slightly outward to accommodate it, and then springs back to resist after insertion). If the thickness of the reinforcing plate is greater than or equal to the thickness of the elastic limiting part 22, a "rigid constraint" will be formed, limiting the deformation range of the elastic limiting part 22, resulting in insufficient resisting force or assembly difficulties. Under the premise of meeting the reinforcement requirements, a thinner reinforcing plate can reduce the amount of material used, especially in mass production, which can significantly reduce the total cost, while conforming to the industry trend of "lightweight design" in automobiles and electronic equipment.

[0043] Furthermore, in some embodiments of this application, a second latching portion 211 is formed on the end face of the body portion 21, and the first latching portion 11 is configured as a first protrusion provided on the side of the first latching member 1 facing away from the elastic limiting portion 22, and the first protrusion is latched onto the end face of the body portion 21 through the latching channel.

[0044] Specifically, the first engaging member 1 protrudes outward from the side opposite to the elastic limiting part 22 to form a first boss, which is the first engaging part 11. The end face of the second sidewall is the second engaging part 211. The first engaging member 1 moves from the entry end to the exit end of the main body 21. When it passes the elastic limiting part 22, the elastic limiting part 22 undergoes a slight deformation in the direction away from the second sidewall, and then the elastic limiting part 22 abuts against the first engaging member 1 under its own elastic force. When the first boss protrudes from the exit end, the first engaging member 1 moves away from the first sidewall of the main body 21 under the abutting force of the elastic limiting part 22, so that the rear side of the first boss engages with the end face of the second sidewall. A double fixation of "elastic abutment + mechanical engagement" is formed, and the assembly is completed.

[0045] The abutting force of the elastic limiting part 22 and the engaging force of the first boss form a "reverse constraint". When the engaging structure is subjected to tensile force, the engaging of the first boss and the end face of the body part 21 prevents the first engaging member 1 from detaching outward, and the abutting force of the elastic limiting part 22 prevents it from shifting inward. At the same time, the elastic limiting part 22 and the second side wall of the body part 21 work together to clamp the first engaging member 1. By setting the reinforcing structure 23, the abutting force of the elastic limiting part 22 on the first engaging member 1 is increased. Even in the high-frequency vibration environment of the vehicle, the loosening rate of the engagement can be greatly reduced.

[0046] In some embodiments of this application, the elastic limiting part 22 is provided with an abutting part 221, which is disposed away from the first groove wall 212 and is used to abut against the first snap-fit ​​member 1.

[0047] The elastic limiting part 22 is fixed at one end and free at the other end. The free end has the largest deformation space. The abutting part 221 is located here to better adapt to the insertion and springback process of the first snap-fit ​​1, avoiding the problem of insufficient deformation and loose abutment due to proximity to the fixed end.

[0048] Furthermore, the elastic limiting part 22 has a second protrusion on the surface facing the first snap-fit ​​member 1, and the second protrusion forms an abutment part 221.

[0049] The abutment portion 221 is configured as an "arc-shaped protrusion" or a "sloping protrusion" to increase the contact area with the first snap-fit ​​component 1. This avoids scratching the surface of the first snap-fit ​​component 1 (especially suitable for plastic and thin metal snap-fit ​​components); at the same time, the sloping surface can guide the insertion of the first snap-fit ​​component 1 and reduce assembly resistance.

[0050] Taking the "sloping protrusion" as an example, when the first snap-fit ​​member 1 is inserted into the snap-fit ​​channel, its side first contacts the sloping surface of the abutment part 221. The sloping surface guides the first snap-fit ​​member 1 into the channel in the correct direction, while simultaneously pressing the abutment part 221. When the first boss (first snap-fit ​​part 11) passes through the snap-fit ​​channel and engages with the end face of the body part 21 (second snap-fit ​​part 211), the abutment part 221 rebounds with the elastic limiting part 22, initially abutting the side of the first snap-fit ​​member 1, providing temporary positioning for the engagement position, and ensuring that the first boss and the end face fit together without gaps. After assembly, under the combined action of the elastic force of the elastic limiting part 22 and the supporting force of the reinforcing plate, the abutment part 221 applies a continuous abutting force to the first snap-fit ​​member 1. This abutting force can offset the gaps caused by vibration, prevent the first snap-fit ​​member 1 from axially moving, and at the same time cooperate with the engagement of the first boss to form a double fixation of "axial locking + radial abutment".

[0051] This application also provides a vehicle in which two mutually structural components are assembled using the snap-fit ​​structure described in the above embodiments. Examples include the assembly of a door panel trim and a door panel bracket, the assembly of a dashboard cover and a dashboard body, and the assembly of a chassis skid plate and a chassis frame.

[0052] Furthermore, such as Figure 2 and Figure 3 As shown, the vehicle includes a bumper 10 and a trim piece 20, one of which is provided with a first snap-fit ​​1 and the other is provided with a second snap-fit ​​2.

[0053] Exemplary examples, in some embodiments of this application, the first snap-fit ​​member 1 is disposed on the bumper 10, and the second snap-fit ​​member 2 is disposed on the trim piece 20. The first snap-fit ​​member 1 and the second snap-fit ​​member 2 connect the bumper 10 and the trim piece 20 together through a combination of "reinforcing plate + abutment part 221 + boss engagement". Even if the vehicle is driving on a bumpy road, the two are not easy to loosen or break, resulting in good structural stability and extending the service life of various vehicle components.
