Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, and in particular to a snap-fit ​​device for a vehicle front-end module. Background Technology

[0002] The hood of a vehicle is typically supported in its open state by a support rod, which is secured by a clip structure mounted on the hood or body. Existing hood support rod clips are mostly vehicle-specific designs, with a single structural form and poor versatility. Different platform vehicles differ in placement, support rod diameter, and installation angle, often requiring the development of custom clips, resulting in long development cycles and high costs. Furthermore, traditional clips usually employ a rigid fit structure, demanding high precision in the position and surface flatness of components during assembly. Assembly errors or manufacturing tolerances can easily cause clip wobble, loosening, or assembly difficulties, thus affecting the overall vehicle assembly quality and lifespan. Especially in the context of the rapid development of automotive platforms and modularization, traditional clip solutions are no longer sufficient to simultaneously meet the needs of multi-platform compatibility and low-cost development. Utility Model Content

[0003] The purpose of this utility model is to address at least one of the aforementioned existing technical problems by providing a snap-fit ​​device for a vehicle front-end module. By adopting an integrated structural design with a support and a base, the base includes a mounting part and at least one elastic arm. The elastic arm undergoes elastic deformation when it abuts against the mounting plate, thereby achieving adaptive compensation for assembly tolerances.

[0004] This utility model provides a snap-fit ​​device for a vehicle front-end module, applied to a support rod. The support rod is fixedly connected to the vehicle front-end module via the snap-fit ​​device. The vehicle front-end module includes a mounting plate with a snap-fit ​​groove. The snap-fit ​​device includes: The support portion can engage with the support rod; The base includes at least one elastic arm, a mounting portion, and a base sidewall. The mounting portion is capable of engaging with the snap-fit ​​groove, and the elastic arm protrudes relative to the base sidewall. When the mounting portion is engaged with the snap-fit ​​groove, the elastic arm abuts against the mounting plate, and the elastic arm is capable of elastic deformation under the abutting force of the mounting plate.

[0005] In a possible implementation, the end of the elastic arm that abuts against the mounting plate has an abutment arc surface.

[0006] In a possible implementation, in the free state of the elastic arm, the elastic arm has a first included angle with the base sidewall; After the elastic arm abuts against the mounting plate and undergoes elastic deformation, a second included angle is formed between the elastic arm and the side wall of the base, and the first included angle is smaller than the second included angle.

[0007] In a possible implementation, the elastic arm is provided with an elastic arm body and a rolled edge structure located on the side of the elastic arm body opposite to the base. When the rolled edge structure abuts against the mounting plate, a gap can exist between the elastic arm body and the mounting plate.

[0008] In a possible implementation, the elastic arm is inclined relative to the sidewall of the base.

[0009] In a possible implementation, the at least one elastic arm includes a first elastic arm and a second elastic arm, the first elastic arm and the second elastic arm being symmetrically arranged about the mounting portion.

[0010] In a possible implementation, the base further includes a support auxiliary member that protrudes relative to the side wall of the base; When the elastic arm deforms to its limit position, the support auxiliary member abuts against the mounting plate.

[0011] In a possible implementation, the support auxiliary member and the elastic arm are arranged adjacent to each other.

[0012] In a possible implementation, a limiting structure is provided on the side wall of the mounting part, which can prevent the mounting part from disengaging from the snap-fit ​​groove.

[0013] In a possible implementation, the support and the base are integrally formed.

[0014] The snap-fit ​​device for a vehicle front-end module provided by this utility model has the following beneficial effects: This utility model provides a snap-fit ​​device for a vehicle front-end module, applied to a support rod. The support rod is fixedly connected to the vehicle front-end module via the snap-fit ​​device. The vehicle front-end module includes a mounting plate with a snap-fit ​​groove. The snap-fit ​​device includes: a support portion capable of engaging with the support rod; and a base including at least one elastic arm, a mounting portion, and a base sidewall. The mounting portion engages with the snap-fit ​​groove, and the elastic arm protrudes relative to the base sidewall. When the mounting portion is engaged with the snap-fit ​​groove, the elastic arm abuts against the mounting plate, and the elastic arm can undergo elastic deformation under the abutment force of the mounting plate. Thus, the elastic deformation of the elastic arm when abutting against the mounting plate absorbs dimensional tolerances between the support rod and the vehicle front-end module during assembly, achieving adaptive limiting and stable support for the support rod, thereby improving the installation reliability of the support rod.

[0020] Understandably, with the rapid development of the automotive industry and the widespread application of platform strategies, the demand for OEMs to share parts across multiple models is increasing. Vehicle hoods are typically supported by support rods to maintain their open position, and the fixing of these support rods largely relies on snap-fit ​​structures. Existing support rod snap-fits are usually designed for specific vehicle models or specific components, such as the vehicle's front-end module 3 or headlight brackets, resulting in poor structural versatility. When the vehicle platform or component structure changes, the existing snap-fits often cannot be directly adapted, requiring redesigned molds or structures, which not only increases development time but also raises production costs. Furthermore, due to significant differences in installation space and component structure across different vehicle models, it is difficult to uniformly control the manufacturing tolerances of related parts. This leads to problems such as gap deviations, assembly difficulties, or loose connections during assembly, affecting the stability of the support rod's fixation.

[0021] like Figure 1-4 As shown, this application provides a snap-fit ​​device for a vehicle front-end module 3, applied to a support rod. The support rod is fixedly connected to the vehicle front-end module 3 via the snap-fit ​​device. The vehicle front-end module 3 includes a mounting plate with a snap-fit ​​groove 31. The snap-fit ​​device includes: Support part 1 can engage with support rod; The base 2 includes at least one elastic arm 21, a mounting portion 22, and a side wall of the base 2. The mounting portion 22 can engage with a snap-fit ​​groove 31, and the elastic arm 21 protrudes relative to the side wall of the base 2. When the mounting portion 22 is engaged with the snap-fit ​​groove 31, the elastic arm 21 abuts against the mounting plate, and the elastic arm 21 can undergo elastic deformation under the abutment force of the mounting plate. Thus, the elastic arm 21, which protrudes relative to the side wall of the base 2, undergoes elastic deformation when it abuts against the mounting plate, which can absorb the dimensional tolerances between the support rod and the vehicle front module 3 during assembly, realize adaptive limiting and stable support for the support rod, and thereby improve the installation reliability of the support rod.

[0022] Understandably, the vehicle front-end module 3 is a functional structural component installed at the front of the vehicle body. Its outer surface is usually a non-planar structure, which may include curved surfaces, reinforcing ribs, or mounting bosses. Due to the complex structure and large tolerances of the vehicle front-end module 3, the snap-fit ​​device needs to have a certain deformation capacity and assembly tolerance absorption capacity to achieve a stable installation connection.

[0023] Specifically, the vehicle front module 3 includes a mounting plate with a snap-fit ​​groove 31. A snap-fit ​​device is mounted on the mounting plate and is used to fix the support rod to the vehicle front module 3. The snap-fit ​​device includes a support part 1 and a base 2. The support part 1 includes a snap-fit ​​opening 11 for engaging with the support rod. The support part 1 can adopt an annular support seat or an open-type sleeve structure, so that the support rod can be stably engaged with the support part 1 by insertion or pressing, thereby limiting the rotation and axial displacement of the support rod.

[0024] Specifically, the base 2 includes at least one elastic arm 21, a mounting portion 22, and a side wall of the base 2. The mounting portion 22 cooperates with a snap-fit ​​groove 31 on the mounting plate, and can be fixed to the mounting plate by insertion or snap-fit. The elastic arm 21 protrudes relative to the side wall of the base 2, with its free end facing the mounting plate. During assembly, after the mounting portion 22 and the snap-fit ​​groove 31 are engaged, the free end of the elastic arm 21 contacts the mounting plate and undergoes elastic deformation under the pressure of the mounting plate. The deformation of the elastic arm 21 causes the snap-fit ​​device to form a pre-tightened state after installation, thereby maintaining a reliable snap-fit ​​force under vehicle vibration or external force. This structure has a certain guiding and self-locking function during assembly, and can achieve quick assembly and disassembly without additional fasteners.

[0025] In one embodiment, the end of the elastic arm 21 that abuts against the mounting plate has an abutment arc surface. Thus, the abutment arc surface can guide the elastic arm 21 to slide smoothly when it deforms, ensuring uniform force distribution, improving assembly smoothness and elastic reset stability, thereby increasing the service life and reliability of the snap-fit ​​device.

[0026] Specifically, the contact arc surface is an arc-shaped structure formed along a direction perpendicular to the normal of the mounting plate. This arc surface can be a cylindrical arc surface or a spherical structure, used to form surface contact or line contact between the elastic arm 21 and the mounting plate, so as to achieve smooth guidance and fit even if there are assembly tolerances.

[0027] In one embodiment, the two sides of the arc surface are connected to the main body of the elastic arm 21 by rounded corners to avoid stress concentration at sharp corners. When not assembled, the free end of the elastic arm 21 has an interference of 0.1-0.6 mm relative to the mounting plate; after assembly, the arc surface abuts against the mounting plate and generates a preload, enabling the elastic arm 21 to provide springback support when subjected to external force, thereby improving the stability of the snap-fit.

[0028] In one embodiment, when the elastic arm 21 is in its free state, the elastic arm 21 has a first included angle with the side wall of the base 2; After the elastic arm 21 comes into contact with the mounting plate and undergoes elastic deformation, there is a second included angle between the elastic arm 21 and the side wall of the base 2, and the first included angle is smaller than the second included angle.

[0029] In this way, the elastic arm 21 can gradually open and generate controllable elastic deformation during the assembly process, achieving a smooth guiding and locking process, avoiding jamming or structural damage caused by excessive instantaneous force; at the same time, the change of the included angle can provide a stable rebound force, so that the locking device automatically resets when released, improving assembly reliability and reusability.

[0030] In one embodiment, when the elastic arm 21 is in its free state, i.e., when there is a gap between the elastic arm 21 and the mounting plate, the elastic arm 21 has a first included angle θ1 with the side wall of the base 2. When the snap-fit ​​device is installed on the mounting plate of the vehicle front module 3, the mounting part 22 is inserted into the snap-fit ​​groove 31 and positioned and fixed, and the free end of the elastic arm 21 gradually contacts the surface of the mounting plate. With further pressing, the mounting plate applies abutment pressure to the elastic arm 21, causing the elastic arm 21 to undergo elastic deformation. At this time, the elastic arm 21 deflects around the root direction of the side wall of the base 2, forming a second included angle θ2 with the side wall of the base 2, where the first included angle θ1 is smaller than the second included angle θ2.

[0031] Preferably, the difference between the second included angle θ2 and the first included angle θ1 is 3° to 10°. In one embodiment, the elastic arm 21 is provided with an elastic arm 21 body and a rolled edge structure located on the side of the elastic arm 21 body opposite to the base 2. When the rolled edge structure abuts against the mounting plate, a gap can exist between the elastic arm 21 body and the mounting plate. Through this gap, the snap-fit ​​device can avoid interference caused by tolerances or deformation during assembly, ensuring the deformation space and resilience of the elastic arm 21, thereby improving the durability, assembly smoothness, and vibration and noise reduction effect of the snap-fit ​​device.

[0032] Specifically, the elastic arm 21 includes an elastic arm 21 body and a rolled edge structure located on the side of the elastic arm 21 body opposite to the base 2. The rolled edge structure is formed by rolling the end of the elastic arm 21 body outward, and can be an arc shape, a semi-circular shape, or a hook shape. The rolled edge structure is used to contact the mounting plate.

[0033] During assembly, the rolled edge structure first comes into contact with the mounting plate. As assembly pressure continues to be applied, the rolled edge structure undergoes local elastic deformation under the action of the mounting plate, thereby absorbing assembly tolerances and providing a buffering effect. At this time, a gap can be maintained between the main body of the elastic arm 21 and the mounting plate. The existence of the gap can prevent the main body of the elastic arm 21 from forming a large area of ​​rigid contact with the mounting plate, avoiding scratches, deformation, or stress concentration caused by assembly deviations.

[0034] In one embodiment, the elastic arm 21 is inclined relative to the side wall of the base 2. In this way, the elastic arm 21 can be gradually stressed and smoothly deformed during the assembly process through the guiding effect of the inclined direction, thereby reducing assembly resistance and improving the smoothness of the snap-fit ​​process.

[0035] In this embodiment, the elastic arm 21 is inclined relative to the side wall of the base 2. The elastic arm 21 extends outward from the side wall of the base 2, and its extension direction forms a preset angle with the side wall of the base 2. The inclined arrangement enables the elastic arm 21 to have a guiding function during assembly. Even if there are deviations in assembly angle or position, it can automatically correct itself through elastic deformation, ensuring smooth assembly. At the same time, this structure can maintain a continuous elastic preload after assembly, improving the stability of the engagement and preventing loosening or abnormal noise under vehicle vibration or thermal expansion and contraction.

[0036] Preferably, the preset included angle is 50° to 80°.

[0037] In one embodiment, such as Figure 2 As shown, at least one elastic arm 21 includes a first elastic arm 211 and a second elastic arm 212, which are symmetrically arranged about the mounting portion 22. In this way, the first elastic arm 211 and the second elastic arm 212 ensure that the locking device is subjected to balanced forces during assembly and stress application, avoiding skewness or loosening caused by unilateral force application; at the same time, the symmetrical arrangement helps maintain a stable locking state under vehicle vibration or impact conditions, improving vibration resistance and structural reliability.

[0038] Specifically, the first elastic arm 211 and the second elastic arm 212 are respectively arranged on both sides of the mounting portion 22. The first elastic arm 211 and the second elastic arm 212 have the same structure, size and tilt angle, and the free ends of the first elastic arm 211 and the second elastic arm 212 extend towards the mounting plate. When the snap-fit ​​device is assembled to the mounting plate, the free ends of the two elastic arms 21 can simultaneously contact the mounting plate and generate elastic deformation, thereby forming a symmetrical force state on both sides of the mounting portion 22.

[0039] Furthermore, the base 2 also includes a support auxiliary member 23, which protrudes relative to the side wall of the base 2; When the elastic arm 21 deforms to its limit position, the support auxiliary member 23 abuts against the mounting plate. In this way, the support auxiliary member 23 can limit the deformation of the elastic arm 21, preventing the elastic arm 21 from undergoing permanent deformation or breakage due to excessive pressure; at the same time, when the support auxiliary member 23 abuts against the mounting plate, it can share the external load, reduce the stress on the elastic arm 21, and improve the durability and impact resistance of the overall structure.

[0040] Optionally, the support auxiliary member 23 can be a boss, a reinforcing rib, or a locally extended block structure.

[0041] Specifically, the end of the support auxiliary component 23 is arranged towards the mounting plate. During assembly, the elastic arm 21 gradually undergoes elastic deformation under the pressure of the mounting plate. When the elastic arm 21 deforms to its limit position, the support auxiliary component 23 abuts against the mounting plate. Through this structural design, when the elastic arm 21 is subjected to excessive force or assembly deviation, the support auxiliary component 23 can act as a limiting support to prevent the elastic arm 21 from continuing to deform excessively, thereby protecting the elastic arm 21 from being crushed or fatigued.

[0042] Preferably, the support auxiliary component 23 is integrally formed with the base 2, and can be directly formed by injection molding or stamping processes.

[0043] In one embodiment, the support auxiliary member 23 and the elastic arm 21 are arranged adjacent to each other. The support auxiliary member 23, which is arranged adjacent to the elastic arm 21, can provide timely support and limit when the elastic arm 21 is deformed by force, thereby shortening the force transmission path.

[0044] In one embodiment, the support auxiliary member 23 and the elastic arm 21 are arranged adjacent to each other. The support auxiliary member 23 is located near the elastic arm 21, and the support auxiliary member 23 and the elastic arm 21 are located on the same side of the base 2, for providing auxiliary support and limiting protection during the operation of the elastic arm 21.

[0045] In one embodiment, the support auxiliary member 23 includes a first support auxiliary member 23 and a second support auxiliary member 23, and the first elastic arm 211, the first support auxiliary member 23, the second elastic arm 212 and the second support auxiliary member 23 are arranged circumferentially along the side wall of the base 2 in sequence.

[0046] In one embodiment, such as Figure 3 and Figure 4 As shown, a limiting structure 222 is provided on the side wall of the mounting part 22, which can restrict the mounting part 22 from disengaging from the snap-fit ​​groove 31. In this way, the limiting structure 222 can mechanically limit the disengagement direction of the mounting part 22 after the snap-fit ​​device is engaged with the snap-fit ​​groove 31, preventing the snap-fit ​​device from loosening under vehicle vibration or external force, thereby improving the reliability and vibration resistance of the snap-fit ​​connection.

[0047] In this embodiment, a limiting structure 222 is provided on the side wall of the mounting part 22. The limiting structure 222 is used to prevent the mounting part 22 from disengaging from the snap-fit ​​groove 31. The limiting structure 222 is formed by protruding outward from the outer wall of the mounting part 22. The limiting structure 222 is wedge-shaped or barbed. The outer surface of the limiting structure 222 is provided with a guide surface that is inclined along the direction of insertion force. The side opposite to the guide surface is the limiting surface.

[0048] Specifically, during assembly, the mounting part 22 is inserted into the locking groove 31 of the mounting plate along the direction of the insertion force. The guide surface of the limiting structure 222 first contacts the groove wall of the locking groove 31 and undergoes local elastic deformation under compression, thereby allowing the mounting part 22 to be inserted smoothly. After the mounting part 22 is fully installed, the limiting surface of the limiting structure 222 automatically engages with the corresponding recess in the groove wall, achieving anti-disengagement locking.

[0049] In one embodiment, a first limiting structure 222 and a second limiting structure 222 are provided on the side wall of the mounting part 22, and the first limiting structure 222 and the second limiting structure 222 are symmetrically arranged about the mounting part 22.

[0050] In one embodiment, the support 1 and the base 2 are integrally molded structures. The integrally molded structure improves the stability and strength of the overall structure and simplifies the manufacturing process; furthermore, it enhances anti-loosening and anti-detachment performance, ensuring a more reliable connection between the support rod and the vehicle front-end module 3.

[0051] Specifically, the support 1 and the base 2 are integrally molded structures, which can be manufactured as a whole by injection molding.

[0052] In one embodiment, the support 1 and the base 2 are made of engineering plastics, such as polyamide (PA66), polycarbonate (PC), or acrylonitrile-butadiene-styrene blend (ABS).

[0053] The following describes the assembly process of a snap-fit ​​device for a vehicle front-end module 3 in an embodiment of this application, using a specific application scenario as an example: First, align the mounting part 22 of the snap-fit ​​device with the snap-fit ​​groove 31 on the mounting plate of the front module 3 of the vehicle, and push the mounting part 22 into the snap-fit ​​groove 31 in a direction perpendicular to the mounting plate. Then, as the mounting part 22 is pushed in, the elastic arm 21 undergoes elastic deformation during the contact with the mounting plate, providing clamping force and positioning function for the mounting part 22. Then, when the mounting part 22 is fully inserted into the snap-fit ​​groove 31 and reaches the predetermined position, the limiting structure 222 cooperates with the snap-fit ​​groove 31 to limit the direction of the mounting part 22's disengagement, thereby completing the fixed installation of the snap-fit ​​device. Finally, align the end of the support rod with the support part 1 of the snap-fit ​​device, and insert the support rod into the support part 1 in the axial direction to achieve the snap-fit ​​connection between the support rod and the support part 1.

[0054] The following describes specific embodiments of this application based on the above technical solution.

[0055] Example 1 Please see Figure 1-4 This embodiment provides a snap-fit ​​device for a vehicle front-end module 3, applied to a support rod. The support rod is fixedly connected to the vehicle front-end module 3 via the snap-fit ​​device. The vehicle front-end module 3 includes a mounting plate with a snap-fit ​​groove 31. The snap-fit ​​device includes: Support part 1 can engage with support rod; The base 2 includes at least one elastic arm 21, a mounting part 22 and a side wall of the base 2. The mounting part 22 can engage with the snap-fit ​​groove 31, and the elastic arm 21 protrudes from the side wall of the base 2. When the mounting part 22 is engaged with the snap-fit ​​groove 31, the elastic arm 21 abuts against the mounting plate, and the elastic arm 21 can undergo elastic deformation under the abutting force of the mounting plate.

[0056] The end of the elastic arm 21 that abuts against the mounting plate has an abutting arc surface. In the free state, the elastic arm 21 has a first included angle with the side wall of the base 2; after the elastic arm 21 abuts against the mounting plate and undergoes elastic deformation, the elastic arm 21 has a second included angle with the side wall of the base 2, and the first included angle is smaller than the second included angle.

[0057] The elastic arm 21 includes a main body and a rolled edge structure located on the side of the main body facing away from the base 2. When the rolled edge structure abuts against the mounting plate, a gap can exist between the main body of the elastic arm 21 and the mounting plate. The elastic arm 21 is inclined relative to the side wall of the base 2. At least one elastic arm 21 includes a first elastic arm 211 and a second elastic arm 212, which are symmetrically arranged about the mounting portion 22. The support portion 1 and the base 2 are integrally formed.

[0058] Example 2 The similarities between Embodiment 2 and Embodiment 1 will not be repeated here. In Embodiment 2, the base 2 also includes a support auxiliary member 23, which protrudes from the side wall of the base 2. When the elastic arm 21 is deformed to its limit position, the support auxiliary member 23 abuts against the mounting plate. The support auxiliary member 23 and the elastic arm 21 are arranged adjacent to each other.

[0059] Example 3 The similarities between Embodiment 3 and Embodiment 1 will not be repeated here. In Embodiment 3, a limiting structure 222 is provided on the side wall of the mounting part 22. The limiting structure 222 can prevent the mounting part 22 from disengaging from the snap-fit ​​groove 31.
