Description

Technical Field

[0001] The present disclosure relates to the technical field of automotive accessories, in particular to a clamping structure, an automotive corner trim, and an automobile. Background Art

[0002] Automobile structures are complex and often require multiple components to be assembled together. After assembly, it is desirable to minimize the exposure of the installation points between components. For example, in the exterior trim connection area between the ventilation cover and the A-pillar, the transition is mainly achieved by adding corner trim components.

[0003] The corner trim can be connected to the ventilation cover. Common connection methods include: using a standard part snap connection between the corner trim and the ventilation cover, which has high clamping strength and is not easily detached, but the installation points are exposed; using a welding form between the corner trim and the ventilation cover, which has high connection strength but affects maintainability due to being non-detachable; there is also a method where the corner trim and the ventilation cover use a self-clamping structure, which takes into account aesthetics and disassembly maintainability, but the connection strength of this clamping structure is relatively weak and the corner trim is easily detached. Summary of the Utility Model

[0004] Based on this, in view of the problem of the relatively weak connection strength between the corner trim and the ventilation cover, it is necessary to provide a clamping structure, an automotive corner trim, and an automobile.

[0005] On the one hand, an embodiment of the present disclosure provides a clamping structure, which is disposed inside the exterior trim layer. The clamping structure includes: a frame body, the frame body includes a first frame portion away from the exterior trim layer and a second frame portion close to the exterior trim layer; a buckle body, located inside the frame body, the root of the buckle body is connected to the frame body, and the head of the buckle body faces the second frame portion; and a rib, connected between the head of the buckle body and the frame body.

[0006] The clamping structure provided with ribs has high structural strength, and the buckle body can better maintain the clamped state.

[0007] In some embodiments, the root of the buckle body is connected to the first frame portion, and the rib is connected between the head of the buckle body and the second frame portion.

[0008] With this setting, the width of the clamping structure can be set to be relatively narrow; the rib can effectively strengthen the structural strength of the buckle body and increase the force required for the buckle body to deform.

[0009] In some embodiments, the first frame portion and the second frame portion are opposite to each other in a first direction, and the dimension of the rib in the first direction is shorter than the dimension of the buckle body in the first direction.

[0010] With this setting, the buckle body has good structural strength and can smoothly deform to achieve clamping.

[0011] In some embodiments, the first frame portion and the second frame portion face each other in the first direction, and along the second direction perpendicular to the first direction of the frame body, the size of the rib is smaller than the size of the buckle body.

[0012] Such a setting is conducive to ensuring the torsional deformation of the buckle body to achieve clamping and disassembly.

[0013] In some embodiments, along the second direction, the rib and the buckle body are centered; along the axis direction of the frame opening of the frame body, the head of the buckle body protrudes from the frame body, and the rib is recessed in the frame body.

[0014] Such a setting helps to ensure the limiting effect of the buckle body and the clamping effect of the clamping structure.

[0015] In some embodiments, the cross-sectional area of the rib is smaller than the cross-sectional area of the root of the buckle body.

[0016] Such a setting enables the buckle body to bear greater stress. While the rib strengthens the buckle body, it ensures the deformation of the buckle body.

[0017] In some embodiments, the rounded corner of the frame opening of the frame body is continuous with the rib.

[0018] Such a setting makes the force on the frame body balanced and the size can be smaller.

[0019] On the other hand, the embodiments of the present disclosure provide an automotive corner trim, which includes: an exterior layer; and the aforementioned clamping structure, and a plurality of clamping structures are arranged along the periphery of the exterior layer.

[0020] By setting the clamping structure, the automotive corner trim can be clamped to the cooperating component in the vehicle, and after clamping, the exterior layer covers the clamping structure; the automotive corner trim can be disassembled, and at the same time, the automotive corner trim is convenient to disassemble and assemble and has high connection strength. A plurality of clamping structures can achieve effective clamping of the automotive corner trim.

[0021] In some embodiments, the automotive corner trim further includes a skeleton, the skeleton is arranged inside the exterior layer, and the clamping structure is connected to the skeleton; the exterior layer is a soft rubber.

[0022] Such a setting ensures the structural strength of the automotive corner trim, enables effective clamping, and ensures that the exterior layer meets the requirements.

[0023] On the other hand, the embodiments of the present disclosure provide a vehicle, which includes the aforementioned automotive corner trim.

[0024] The vehicle provided by the embodiments of the present disclosure has a complete and beautiful appearance, there is no leakage of the installation structure at the automotive corner trim, and it also has good maintainability. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Refer to Figure 1 and Figure 2 , wherein Figure 2Shows the automotive corner trim of the embodiments of the present disclosure. The automotive corner trim 100 provided by the embodiments of the present disclosure can be used to be installed in the vehicle 1000, for example, snap-connected to the ventilation cover plate 200.

[0038] In an exemplary embodiment, the automotive corner trim 100 includes an exterior layer 1 and a snap-fit structure 2, and the snap-fit structure 2 is disposed inside the exterior layer 1. As Figure 1 shown, the side of the exterior layer 1 facing the ventilation cover plate 200 can be referred to as the inner side, and the side facing away from the ventilation cover plate 200 can be referred to as the outer side.

[0039] Referring to Figure 1 and Figure 3 , in an exemplary embodiment, the snap-fit structure 2 includes a frame body 21, a buckle body 22 and a rib 23. Taking the attitude of the snap-fit structure 2 in Figure 1 as an example, in this snap-fit structure 2, the buckle body 22 can at least partially protrude from the frame body 21 along the X-axis direction so as to be abutted against the ventilation cover plate 200 substantially along the Z-axis direction.

[0040] The frame body 21 includes a first frame portion 211 away from the exterior layer 1 and a second frame portion 212 close to the exterior layer 1. The frame body 21 further includes a third frame portion 213 and a fourth frame portion 214 connected between the first frame portion 211 and the second frame portion 212. The frame body 21 can be generally rectangular, or other shapes such as a rounded rectangle. As Figure 3 shown, exemplarily, the dimension of the frame body 21 along the Z-axis direction can be greater than its dimension along the Y-axis direction.

[0041] The buckle body 22 is located inside the frame body 21. The buckle body 22 can include a head 221 and a root 222. The head 221 is used to abut against the mating part, and the root 222 can be deformed to achieve snap-fitting and disassembly. The root 222 of the buckle body 22 is connected to the frame body 21, and the head 221 of the buckle body 22 faces the second frame portion 212.

[0042] The rib 23 is connected between the head 221 of the buckle body 22 and the frame body 21. The snap-fit structure 2 provided with the rib 23 has high structural strength, and the buckle body 22 can better maintain the snap-fit state and has stable snap-fitting ability.

[0043] By providing the snap-fit structure 2, the automotive corner trim 100 can be snap-connected to the mating part in the vehicle 1000, and after snap-connection, the exterior layer 1 covers the snap-fit structure 2. The automotive corner trim 100 is convenient to disassemble and assemble and has high connection strength, avoiding accidental detachment of the automotive corner trim 100 from the ventilation cover plate 200, and can be detached from the ventilation cover plate 200 when maintenance is required, and can meet the maintenance requirements of multiple detachable times.

[0044] Exemplarily, the root 222 of the buckle body 22 is connected to the first frame portion 211, as Figure 3As shown, the buckle body 22 extends substantially along the Z-axis direction, with a simple and reliable structure. In some other embodiments, the root portion 222 is provided on the third frame portion 213 and / or the fourth frame portion 214, or is provided at the connection between the third frame portion 213 and the first frame portion 211. Exemplarily, the root portion 222 can be a complete whole or can be divided into multiple structures.

[0045] In some embodiments, the rib 23 is connected between the head 221 of the buckle body 22 and the second frame portion 212. Refer to Figure 3 , the distances between the third frame portion 213 and the fourth frame portion 214 and the buckle body 22 are both relatively close, specifically closer than the distance between the second frame portion 212 and the buckle body 22. The dimension of the clamping structure 2 in the Y-axis direction can be referred to as the width, and the width of the clamping structure 2 can be set to be relatively small. The rib 23 can effectively strengthen the structural strength of the buckle body 22 and enhance the force required for the buckle body 22 to deform.

[0046] In some other embodiments, the rib 23 is provided on the third frame portion 213 and / or the fourth frame portion 214, or is provided at the connection at both ends of the second frame portion 212. Exemplarily, the clamping structure 2 can include one rib 23 or multiple ribs 23.

[0047] In some embodiments, the first frame portion 211 and the second frame portion 212 face each other in the first direction. As Figure 3 shown, the first direction can be parallel to the Z-axis direction. The dimension of the rib 23 in the first direction is shorter than the dimension of the buckle body 22 in the first direction. The buckle body 22 has good structural strength and can smoothly deform to achieve clamping. Exemplarily, the dimension of the buckle body 22 in the first direction is greater than half of the distance between the first frame portion 211 and the second frame portion 212.

[0048] Relative to the Z-axis direction, the XY plane is its perpendicular plane, and the cross-section of the clamping structure 2 can be a plane parallel to the XY plane. In some embodiments, the cross-sectional area of the rib 23 is smaller than the cross-sectional area of the root portion 222 of the buckle body 22. The rib 23 can achieve relatively small stress, while the buckle body 22 bears greater stress. While strengthening the buckle body 22, the rib 23 ensures the deformation of the buckle body 22 to smoothly perform clamping and disassembly.

[0049] Exemplarily, the clamping structure 2 is an integral structure. The material of the rib 23 is the same as the material of the buckle body 22.

[0050] Refer to Figure 3, in some embodiments, the housing 21 has a second direction perpendicular to the first direction, and the second direction can be parallel to the Y-axis direction. Exemplarily, along the second direction of the housing 21, the size of the rib 23 is smaller than the size of the buckle 22. During the process of inserting the snap structure 2 into the ventilation cover plate 200, it may not be completely aligned and may have a certain inclination. The buckle 22 is wider than the rib 23, and then the buckle 22 can effectively twist and deform to adapt to various force conditions to achieve snapping and disassembly.

[0051] Exemplarily, the size range of the rib 23 along the second direction is 4 mm to 5 mm, such as 4.5 mm. The size range of the rib 23 along the third direction is 1 mm to 1.5 mm, such as 1.2 mm. The rib 23 can effectively inhibit the shaking of the housing 21 and the buckle 22 during the installation process, and then helps to avoid the snap structure 2 falling due to insufficient snap strength.

[0052] In some embodiments, along the second direction, the rib 23 and the buckle 22 are centered, the buckle 22 is evenly stressed, and the rib 23 connects to the middle position of the buckle 22, which helps to ensure the limiting effect of the buckle 22.

[0053] Combined with Figure 1 As shown, the axis direction of the frame opening of the housing 21 can be referred to as the third direction, and the third direction can be parallel to the X-axis direction. Along the axis direction of the frame opening of the housing 21, the head 221 of the buckle 22 protrudes from the housing 21, and the rib 23 is recessed in the housing 21. Specifically, the head 221 has a snap surface 220, and the snap surface 220 can extend out of the housing 21. On the side where the snap surface 220 extends out, the rib 23 is recessed, which is beneficial to making the snap surface 220 have a larger area. On the other side, the rib 23 can be flush with the housing 21, which is easy to manufacture. By configuring the structural position of the rib 23, the force application mode of the rib 23 on the buckle 22 can be controlled, which helps to ensure the snapping effect of the snap structure 2.

[0054] Exemplarily, the root 222 may have an inclined surface 2221, and the inclined surface 2221 faces away from the snap surface 220. When the snap structure 2 is inserted into the ventilation cover plate 200, the inclined surface 2221 is beneficial to guiding the buckle 22 to gradually deform and ensuring that the head 221 is snapped in place.

[0055] Exemplarily, the root 222 of the buckle 22 is longer than the head 221. The inclined surface 2221 extends from the head 221 to the first frame portion 211. Relative to the first direction, the slope of the inclined surface 2221 is smaller than the slope of the snap surface 220. Exemplarily, the root 222 includes a bottom plate and two vertical ribs. The bottom plate is connected to the first frame portion 211, the head 221 protrudes from the bottom plate along the axis of the frame opening, the two vertical ribs are connected to the head 221 and are longer than the bottom plate, and the two vertical ribs extend into the first frame portion 211.

[0056] Refer to Figure 3, the housing 21 has a housing opening 210. In the housing 21, adjacent two housing parts can be transitioned with rounded corners. For example, a first rounded corner 201 of the housing opening 210 is formed between the second housing part 212 and the third housing part 213, and a second rounded corner 202 is formed between the third housing part 213 and the first housing part 211. The force on the housing 21 is balanced, stress concentration is reduced, which helps to improve the service life.

[0057] In some embodiments, the size of the housing 21 is small, and the layout of the housing 21, the buckle 22 and the rib 23 is relatively compact. Exemplarily, the first rounded corner 201 is continuous with the rib 23. Refer to Figure 3 , along the second direction, the rib 23 is substantially equal in length to the straight edge of the second housing part 212. The size of the second housing part 212 can be small, while ensuring the deformation ability of the rib 23, and appropriately enhancing the structural strength of the clamping structure 2.

[0058] Exemplarily, the first housing part 211 and the root part 222 are smoothly transitioned, and the second rounded corner 202 of the housing opening 210 can be formed by the third housing part 213, the first housing part 211 and the root part 222. The design of the second rounded corner 202 is beneficial to strengthening the root part 222 and also dispersing the force on the first housing part 211.

[0059] Refer to Figure 1 , in some embodiments, the automotive corner trim 100 further includes a skeleton 3. The skeleton 3 is disposed inside the exterior layer 1, and the clamping structure 2 is connected to the skeleton 3. The skeleton 3 ensures the structural strength of the automotive corner trim 100 and can be effectively clamped. Exemplarily, the skeleton 3 and the clamping structure 2 can be integrally formed.

[0060] Exemplarily, the exterior layer 1 is a soft rubber, and the hardness and strength of the skeleton 3 can be greater than those of the exterior layer 1, ensuring that the exterior layer 1 meets the requirements. The exterior layer 1 can be disposed on the skeleton 3 by injection molding or the like.

[0061] Refer to Figure 2 , in some embodiments, a plurality of clamping structures 2 are arranged along the periphery of the exterior layer 1. The connection of the periphery of the exterior layer 1 is reliable, avoiding warping. The automotive corner trim 100 has a simple structure, a light weight, and a clamping structure 2 with relatively high strength. The automotive corner trim 100 can be effectively clamped and avoid falling off.

[0062] Refer to Figure 1 and Figure 4 , the present disclosure embodiment provides an automobile 1000, and the automobile 1000 includes an automotive corner trim 100. By configuring the clamping structure 2, the automobile provided by the present disclosure embodiment has a complete and beautiful appearance, no leakage of the installation structure at the automotive corner trim, and can also have good maintainability.

[0063] Exemplarily, the vehicle 1000 further includes a ventilation cover plate 200, which can be snap-connected to the vehicle corner trim 100. The vehicle 1000 may further include a water trough 300, and the water trough 300 can be connected to the ventilation cover plate 200.

[0064] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0065] The above-disclosed embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the patent protection scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can be made, and these all belong to the patent protection scope required by the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
