Description

Technical Field

[0001] The utility model relates to the field of automobile interior decoration, in particular to a foam-coated interior decoration part. Background Art

[0002] The foam-covered interior of a car refers to the use of foam materials to cover or wrap some surfaces or components inside the car to achieve the effect or purpose of improving softness, comfort or aesthetics.

[0003] The foam-covered interior part includes a hardware body and a foam body located on the hardware body. The hardware body is provided with a foam groove, and the foam body is foamed and formed in the foam groove. In the prior art, the hardware body and the foam body are foamed as one body, and the side surface of the inner wall of the foam groove is a vertical surface ( Figure 1 As shown in the figure 5, the vertical surface is the soft and hard junction of the foam body and the hardware body (junction Figure 4 As shown, the soft-hard junction is the vertical line between the foam body 8 and the hardware body 1 in the figure). When the foam body 8 is subjected to external artificial downward pressure, the foam body is deformed by the pressure and is easily separated from the hardware body. In this way, the soft-hard junction is prone to collapse during use, thereby affecting the appearance of the car interior. Utility Model Content

[0004] The utility model aims to provide a foam-covered interior decoration part, so as to solve the problem that the soft and hard joints of the foam-covered interior decoration part are easily separated when pressed downward.

[0005] To achieve the above purpose, the utility model adopts the following technical solution: a foam-covered interior component, including a hardware body and a foam body, the hardware body is provided with a foam groove, the foam body is located in the foam groove, the edge of the foam groove is provided with a slope, and the foam body is provided with an extension portion extending to the slope.

[0006] The principle and advantage of this solution are: the foam groove on the hardware body is used to accommodate the foam body, and the foam body is foamed and formed in the foam groove, thereby filling the foam groove. In this solution, the edge of the foam groove is provided with an inclined surface. When the foam body foams, the foaming spreads to the inclined surface. The part of the foam body extending to the inclined surface is the extension part, and the extension part and the inclined surface are connected. In this way, when the edge part of the foam body is subjected to downward pressure, due to the connection between the extension part and the inclined surface, the inclined surface has a certain supporting effect on the extension part. Through the connection between the extension part and the inclined surface, the soft and hard junction between the foam body and the foam groove is not easy to separate, and the force strength of the soft and hard junction is better, which solves the problem of collapse of the foam body coating at the soft and hard junction after being compressed in the prior art.

[0007] Preferably, as an improvement, the hardware body is an armrest body, and the foam groove is located at the top of the armrest body. The foam-covered interior part in this application is an armrest. Since the armrest part of the car has a high contact frequency with the hand and the foam body is prone to collapse after being pressed, the solution in this application is applied to the armrest with a high contact frequency with the hand.

[0008] Preferably, as an improvement, the inclined surface is located at the edge of the end of the foam groove. In the prior art, the places where collapse is likely to occur at the soft-hard junction are mostly located at the end of the foam groove of the armrest body. Therefore, this solution sets the inclined surface at the edge of the end of the foam groove to solve the problem of easy collapse at the soft-hard junction.

[0009] Preferably, as an improvement, a plurality of weakening holes are provided at the bottom of the foam groove, and the weakening holes are strip-shaped.

[0010] In this application, the weakening holes are structures for vehicle collision weakening. Adding weakening holes can absorb energy during a car collision, weaken the strength of the armrest body, and prevent the armrest body from being too strong during the collision of the door panel and causing damage to the human body.

[0011] Preferably, as an improvement, the plurality of weakening holes are arranged in sequence along the X direction of the armrest body.

[0012] The X direction of the armrest body is the length direction of the armrest and also the front-rear direction of the car.

[0013] Preferably, as an improvement, the length direction of the weakening hole is the Y direction of the armrest body.

[0014] The Y direction of the armrest body is the width direction of the armrest and also the left-right direction of the car.

[0015] In this application, by limiting the arrangement method of the plurality of weakening holes and the setting direction of a single weakening hole, the energy absorption effect of the weakening holes is good during the collision process.

[0016] Preferably, as an improvement, one end of the weakening hole is a tip. Thus, when the weakening hole is damaged, it starts to be damaged from the tip. The setting of the tip makes the weakening hole more likely to fester and be damaged for energy absorption after the armrest body is collided.

[0017] Preferably, as an improvement, the tip points to the side of the armrest body away from the human body. Thus, since the tip will fester and be damaged after being collided, the tip points to the side of the armrest body away from the human body, and the tip is far from the human body, avoiding the tip invading the human body after the weakening hole festers and is damaged.

[0018] Preferably, as an improvement, the number of weakening holes is 5 - 10.

[0019] Preferably, as an improvement, a plurality of reinforcing ribs are provided on the back surface of the armrest body. The plurality of reinforcing ribs are sequentially arranged along the X direction of the armrest body. The reinforcing ribs are located outside the weakening holes. The reinforcing ribs include vertical ribs in the Z direction and horizontal ribs in the Y direction. The vertical ribs are located on the vertical side walls of the armrest body, and the horizontal ribs are located at the bottom of the foam groove.

[0020] Therefore, in this application, since a plurality of weakening holes are provided at the bottom of the foam groove, although energy can be absorbed during a collision, the bottom of the foam groove is prone to festering and damage. However, due to the setting of the weakening holes, the strength of the bottom of the foam groove becomes lower. And the Z direction of the armrest needs to bear the pressure of the hand, and the strength of the bottom of the foam groove is insufficient and easy to be damaged. Therefore, in this application, a plurality of reinforcing ribs are provided. The reinforcing ribs can support the bottom of the foam groove, improve the stress strength of the bottom of the foam groove in the Z direction, improve the Z-direction bearing capacity of the armrest, and at the same time, after the armrest body is collided, the weakening holes can still fester and be damaged, and the reinforcing ribs will not affect the energy absorption ability of the weakening holes.

[0026] The following is further detailed through specific embodiments:

[0027] The reference numerals in the accompanying drawings of the specification include: hardware body 1, foam groove 2, weakening hole 3, tip 4, inner side surface 5, inclined surface 6, reinforcing rib 7, foam body 8, extension part 9.

[0028] Embodiment 1

[0029] Basically as shown in the attached Figures 1 - 3 , Figure 5 figures: A foam-coated interior part includes a hardware body 1 and a foam body 8. In this embodiment, the foam-coated interior part takes the armrest located inside the car door panel as an example for illustration.

[0030] Combined with Figure 1As shown, the hardware body 1 in this embodiment is an armrest body, and the hardware body 1 is made by plastic injection molding. A foam groove 2 is provided at the top of the hardware body 1. Combined with Figure 3 As shown, the foam body 8 is foamed in the foam groove 2, and the foam groove 2 accommodates the foam body 8. The foam body 8 is made of foam material, and its forming method is foaming in the foam groove 2.

[0031] Combined with Figure 1 As shown, a slope 6 is provided at the edge of the foam groove 2. In this embodiment, the slope 6 is located on the edge of the inner side 5 at both ends of the foam groove 2. Combined with Figure 3 As shown, after the foam body 8 is foamed in this embodiment, an extension part 9 extending to the slope 6 is integrally provided on the foam body 8.

[0032] Thus, when downward pressure is applied to the edge parts of the foam body 8 at both ends of the foam groove 2, combined with Figure 5 As shown, due to the connection between the extension part 9 and the slope 6, the slope 6 has a certain supporting effect on the extension part 9. Through the connection between the extension part 9 and the slope 6, the soft-hard junction between the foam body 8 and the foam groove 2 is not easily separated, and the stress intensity at the soft-hard junction is better, solving the problem that the foam body 8 at the soft-hard junction at both ends of the foam groove 2 in the prior art collapses after being pressed and covered. In this way, when the armrest is in use, after the foam body 8 at both ends of the foam groove 2 is manually pressed, due to the support of the slope 6 on the extension part 9, the foam body 8 is not easily separated from the hardware body 1, and there will be no problem of collapse and pit. The surface of the armrest is relatively flat and beautiful.

[0033] Embodiment 2

[0034] This embodiment is improved on the basis of Embodiment 1. Specifically, a plurality of weakening holes 3 are provided at the bottom of the foam groove 2, and the weakening holes 3 are strip-shaped. The plurality of weakening holes 3 are arranged in sequence along the X direction of the armrest body (the X direction is the length direction of the armrest body, that is, the front-back direction of the vehicle). The length direction of the weakening holes 3 is the Y direction of the armrest body (the Y direction is the width direction of the armrest body, that is, the left-right direction of the vehicle body). One end of the weakening hole 3 is a tip 4, and the other end is a wide end. The shape of the weakening hole 3 is triangular, and the wide end is similar to the bottom edge of the triangle. The tip 4 points to the side of the armrest body away from the human body (the side pointed by the tip 4 is the side of the vehicle door panel, and the wide end faces the human body and is close to the human body). The number of weakening holes 3 in this embodiment is 5 - 10.

[0035] Thus, when a vehicle collision occurs, the presence of the weakening holes 3 in the armrest body makes the armrest body easily damaged at the tip 4 for energy absorption, thereby reducing the damage to the human body by the armrest body. At the same time, the tip 4 of the armrest body is on the side away from the human body, so that after the tip 4 is damaged, it will not invade the human body, which is beneficial to reducing the infringement on the human body.

[0036] Embodiment 3

[0037] Combined Figure 2 As shown, on the basis of Embodiment 2, this embodiment is further limited. A plurality of reinforcing ribs 7 are provided on the back surface of the armrest body. The plurality of reinforcing ribs 7 are arranged in sequence along the X direction of the armrest body. The reinforcing ribs 7 are located outside the weakening holes 3. The reinforcing ribs 7 include vertical ribs in the Z direction and horizontal ribs in the Y direction. The vertical ribs are vertically arranged and integrally located on the vertical side wall of the armrest body. The horizontal ribs are horizontally arranged and integrally located at the bottom of the foam groove 2. The direction of the horizontal ribs is parallel to the length direction of the weakening holes 3.

[0038] In this application, since a plurality of weakening holes 3 are provided at the bottom of the foam groove 2, although energy absorption can be carried out during the collision process, the bottom of the foam groove 2 is easily festered and damaged. However, due to the setting of the weakening holes 3, the strength of the bottom of the foam groove 2 becomes lower. And the Z direction of the armrest needs to bear the pressure of the hand. If the strength of the bottom of the foam groove 2 is not enough, it is easily damaged. Therefore, in this application, a plurality of reinforcing ribs 7 are provided. Through the supporting action of the vertical ribs and horizontal ribs of the reinforcing ribs 7, the reinforcing ribs 7 can support the bottom of the foam groove 2, improving the force-bearing strength of the bottom of the foam groove 2 in the Z direction and the Z-direction bearing capacity of the armrest. At the same time, the reinforcing ribs 7 are located outside the weakening holes 3 (the distance between the tip 4 of the weakening hole 3 and the horizontal ribs is 8-10 mm). The reinforcing ribs 7 will not strengthen the weakening holes 3. After the armrest body is collided, the weakening holes 3 can still fester and be damaged, and the reinforcing ribs 7 will not affect the energy absorption ability of the weakening holes 3.

[0039] The above are only the embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
