Description

Technical Field

[0001] The utility model relates to the technical field of vehicle carpet structures, in particular to a vehicle carpet structure.

[0002] The utility model also relates to a vehicle slide rail installation structure having the vehicle carpet structure. Background Art

[0003] With the development of technology and the improvement of people's living standards, people have higher and higher requirements for the comfort of vehicles when using them. Nowadays, whether it is a family car or a company car, factors that affect the comfort of riding in a vehicle, such as the texture of use and driving noise, are important factors that consumers need to give priority to when buying a car.

[0004] The main function of the carpet assembly in the vehicle is to cover the floor sheet metal, block the structure on the floor sheet metal and allow passengers to step on it when riding. The feeling of stepping on the carpet is the most direct aspect that affects the passengers' perception of the comfort of the carpet. Secondly, the carpet is also an important acoustic part inside the vehicle. It has certain sound insulation and sound absorption capabilities and makes an important contribution to the acoustic performance of the entire vehicle. Taking the more common tufted carpet as an example, the tufted carpet is generally composed of three layers: nylon tufted soft surface, EVA (ethylene-vinylacetate copolymer, ethylene-vinyl acetate copolymer) heavy coating and non-woven fabric. Its production process is generally to weave nylon and polyester yarn into a tufted carpet surface, and then put the nylon tufted soft surface, EVA heavy coating and non-woven fabric into a mold for hot pressing. Although the tufted carpet can cover the vehicle floor sheet metal more closely, its sound absorption and sound insulation capabilities are limited and cannot meet people's demand for low noise in the vehicle interior environment.

[0005] In some high-end vehicles, in order to improve the sound insulation and sound absorption capabilities of the carpet, a layer of PU (polyurethane) foam material is added to the back of the carpet. The PU layer can effectively isolate and absorb the noise from the bottom of the vehicle. However, when stepping on the carpet with the PU layer, there will be a noticeable sense of collapse, which provides insufficient support for the feet and affects the quality of vehicle use. Utility Model Content

[0006] In view of this, the utility model aims to provide a vehicle carpet structure to improve the use quality of the vehicle.

[0007] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0008] A vehicle carpet structure is supported on a floor sheet metal, and the vehicle carpet structure comprises:

[0009] A bottom foam body supported and held on the floor sheet metal;

[0010] A reinforcement body, embedded in the bottom foam body, wherein the strength of the reinforcement body is greater than the strength of the bottom foam body;

[0011] A carpet is fixedly laid on the upper surface of the bottom foam body.

[0012] Furthermore, the reinforcement body is made of foam material.

[0013] Furthermore, the bottom foam body is made of polyurethane material, and the reinforcement body is made of foamed polypropylene.

[0014] Furthermore, the bottom surface of the bottom foam body conforms to the supporting surface of the floor sheet metal due to foaming.

[0015] Furthermore, the upper surface of the reinforcement body and the upper surface of the bottom foam body are located in the same plane.

[0016] Furthermore, the carpet has a free section, and the free section is extended outward from the edge of the bottom foam body along the width direction of the vehicle.

[0017] Furthermore, two side surfaces of the bottom foam body in the vehicle width direction are configured as inclined surfaces, and the inclined surfaces are arranged to expand outward from the bottom to the top of the bottom foam body.

[0018] Compared with the prior art, the utility model has the following advantages:

[0019] The vehicle carpet structure described in the utility model is provided with a three-layer structure, in which a bottom foam body is connected to a floor sheet metal, and can absorb and isolate the noise generated at the vehicle chassis, and effectively reduce the noise inside the vehicle during driving; the middle-layer structure is provided as a reinforcing body with a strength greater than that of the bottom foam body, and can provide a relatively firm supporting foundation for the upper carpet, so that the upper carpet will not sink excessively after being subjected to pressure such as being stepped on, and the supporting effect is better, thereby improving the use texture of the vehicle, and at the same time, the vehicle carpet structure is not easy to be dented after long-term use, thereby improving its service life; the carpet is fixed on the upper surface of the bottom foam body, so that the vehicle carpet structure has a better surface appearance.

[0020] Secondly, the reinforcement body is made of foam material, which can form a relatively tight and firm connection with the bottom foam body, and the manufacturing process is simple and efficient, and the manufacturing cost is also low. The bottom foam body is made of polyurethane foam, which not only has good sound absorption and sound insulation effects, but also has effective thermal insulation functions. At the same time, it is moisture-proof and water-proof, which fully isolates the interior space from the chassis and improves the comfort of use in the vehicle; the reinforcement body made of polypropylene has a good buffering and supporting effect. Even if the thickness is small, it can also play a good role in supporting the upper structure. The bottom foam body is formed by directly foaming on the floor sheet metal, which can naturally follow the shape of the floor sheet metal, has high molding efficiency, and has a better connection effect with the floor sheet metal.

[0021] Furthermore, the reinforcement body is embedded in the bottom foam body, and the top is flush with the bottom foam body, which can directly contact the upper carpet. After the passenger steps on the carpet above the reinforcement body, the reinforcement body can transfer the pressure to the bottom foam body more evenly downward, so that the bottom foam body is not easily locally compressed and dented, thereby improving the support effect of the reinforcement body. The free section of the carpet can better shield the lower structure. When the carpet is stepped on by the passenger, it will shrink toward the stepped part. The two sides of the bottom foam body are set to an upward and outward expansion shape, and the edge of the bottom foam body has a better support and anti-shrinkage effect on the carpet. At the same time, it can also reduce the amount of raw materials used in the bottom foam body, reduce costs, and reduce the weight of the entire vehicle.

[0022] Another object of the utility model is to provide a vehicle slide rail installation structure, which includes a slide rail, and a plurality of the above-mentioned vehicle carpet structures are arranged on the floor sheet metal, and each of the vehicle carpet structures is spaced apart along the width direction of the vehicle to form an installation cavity for accommodating the slide rail.

[0023] Furthermore, in the height direction of the vehicle, the interference between the edge of the slide rail and the carpet is 2.8 mm to 3.2 mm.

[0024] Further, in the width direction of the vehicle, the carpet has a matching section pressed and covered under the edge of the slide rail.

[0025] The vehicle slide rail installation structure described in the utility model sets the slide rails between adjacent vehicle carpet structures. Because the number of slide rails is large and the carpet structure between adjacent slide rails is relatively slender in shape, by arranging a plurality of the above-mentioned vehicle carpet structures, the slender vehicle carpet structure can also play a better supporting role for the slide rails and the occupants.

[0026] Secondly, the Z-direction compression between the slide rail and the carpet is set, so that the slide rail can press the carpet firmly without causing excessive deformation on the carpet surface, and the appearance of the intersection between the slide rail and the carpet is better. A matching section is set on the edge of the carpet. When the occupant steps on the carpet, even if the carpet shrinks to a certain extent, the structure under the carpet is not easily exposed, and the appearance is better.

[0048] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0049] Embodiment 1

[0050] The present embodiment relates to a vehicle carpet structure, which optimizes the structure of the vehicle carpet assembly to enhance the riding comfort inside the vehicle and improve the quality of vehicle use.

[0051] In terms of overall structure, the vehicle carpet structure of this embodiment is supported on the floor sheet metal, and includes a bottom foam body 1, a reinforcement body 3, and a carpet 4. The bottom foam body 1 is supported and maintained on the floor sheet metal. The reinforcement body 3 is embedded in the bottom foam body 1, and the strength of the reinforcement body 3 is greater than that of the bottom foam body 1. The carpet 4 is fixedly laid on the upper surface of the bottom foam body 1.

[0052] As set above, the vehicle carpet structure is set as a three-layer structure. The bottom foam body 1 of the bottom layer is connected to the floor sheet metal, which can absorb and isolate the noise generated by the vehicle chassis, effectively reducing the noise inside the vehicle during driving. The middle layer structure is set as a reinforcement body 3 with a strength greater than the bottom foam body 1, which can provide a relatively firm support foundation for the upper carpet 4, so that the upper carpet 4 will not sink excessively after being stepped on or the like. The support effect is better, which improves the texture of the vehicle. At the same time, it also makes the vehicle carpet structure less likely to sag after long-term use, thereby increasing its service life. The upper carpet 4 is fixed on the upper surface of the bottom foam body 1, so that the vehicle carpet structure has a better surface appearance.

[0053] Based on the above overall introduction, refer to Figure 1 Specifically, the bottom foam body 1 is connected to the floor sheet metal. By adjusting the thickness of the bottom foam body 1, a relatively flat plane can be formed on the top of the bottom foam body 1. After the carpet 4 on the top is laid on this plane, the overall appearance is smooth and neat, and it is not easy to cause obstacles to the feet of passengers. The reinforcement body 3 is bonded to the bottom foam body 1, which can enhance the support strength of the bottom foam body 1 to the carpet 4, so that when the passengers step on the carpet 4, the collapse degree of the bottom foam body 1 is reduced, and the stepping feeling is better.

[0054] As for the specific type of carpet 4, tufted carpet, needle-punched carpet or PVC (Polyvinylchloride) carpet can be selected. Tufted carpet is mostly used in mid-to-high-end vehicles. It has good heat insulation and sound insulation effects, and its appearance and texture are higher in grade. However, the manufacturing process is relatively complicated, and the quality is large and the cost is high. Needle-punched carpet is a common type for mid-to-low-end vehicles. Although its appearance and texture are average, its manufacturing process is simple and the price is relatively low. PVC carpet is easy to clean and has low manufacturing cost, but its molding appearance is poor and it will emit a pungent odor for a long time. It is generally used in vehicles of operating types such as taxis and online car-hailing. According to the advantages and disadvantages of the above-mentioned carpet types, the type of carpet 4 can be selected according to actual needs. In this embodiment, the carpet 4 adopts a tufted carpet.

[0055] In order to facilitate the manufacture of the reinforcement body 3, the reinforcement body 3 is made of a foaming material, the manufacturing process is simple and efficient, and the manufacturing cost is also low. The reinforcement body 3 is made of a foaming material, which can produce a relatively strong connection with the bottom foam body 1, and the contact surface is tight and has no gaps. When manufacturing the reinforcement body 3, the reinforcement body 3 can be foamed first, and then the bottom foam body 1 is foamed around it; or the bottom foam body 1 can be foamed first, while leaving a foaming cavity for the reinforcement body 3, and then the reinforcement body 3 is foamed.

[0056] As for the specific available materials of the bottom foam body 1 and the reinforcement body 3, for example, the bottom foam body 1 is made of polyurethane material, and the reinforcement body 3 is made of foamed polypropylene. The foamed polyurethane structure itself has many high-resilience soft foams, and its resilience provides excellent shock absorption function for the carpet 4, making the passengers comfortable to step on. The foamed polyurethane has a large number of evenly distributed open micropores inside, which can convert sound waves into heat energy dissipation through friction and viscosity after entering, thereby weakening the sound waves and achieving the effect of sound absorption and sound insulation. At the same time, the porous structure in the foamed polyurethane can also play a role in heat insulation. Secondly, the foamed polyurethane also has a good anti-penetration ability, which fully isolates the interior space of the car from the chassis, and water vapor is not easy to penetrate, which improves the comfort of the vehicle. The reinforcement body 3 made of polypropylene has a good buffer support effect, even if the thickness is small, it can also play a good effect of supporting the upper structure, and the molding process is simple.

[0057] In order to improve the connection effect between the bottom foam body 1 and the floor sheet metal, the bottom surface of the bottom foam body 1 follows the support surface of the floor sheet metal due to foaming. The bottom foam body 1 is formed by directly foaming on the floor sheet metal, which can make it naturally follow the shape of the floor sheet metal, maximize the contact area with the support surface of the floor sheet metal, and make the connection strength between the bottom foam body 1 and the floor sheet metal higher. At the same time, the NVH (Noise, Vibration, Harshness) treatment effect of the whole vehicle is improved, and the noise and vibration from the chassis are effectively blocked. In addition, the bottom foam body 1 can also better cover other structures set on the floor sheet metal, and play a certain protective role for these structures.

[0058] Specifically, because the floor sheet metal is not flat and has many convex or concave structures on its surface, the thickness of the bottom foam body 1 is set to 22mm-33mm. The thickness difference can make up for the convex or concave structures on the floor sheet metal surface, so that the upper surface of the bottom foam body 1 can be more flat. If the thickness of the bottom foam body 1 is less than 22mm, the vehicle carpet structure will feel hard when stepped on; if the thickness of the bottom foam body 1 is greater than 33mm, the vehicle carpet structure will feel too soft when stepped on, and the weight of the vehicle will also be increased.

[0059] Regarding the specific position of the reinforcement body 3 in the bottom foam body 1, the upper surface of the reinforcement body 3 in this embodiment is located in the same plane as the upper surface of the bottom foam body 1. The reinforcement body 3 is embedded in the bottom foam body 1, and the top is flush with the bottom foam body 1, and can directly contact the upper carpet 4. After the occupant steps on the carpet 4 above the reinforcement body 3, the reinforcement body 3 can transfer the pressure it receives downward to the bottom foam body 1 more evenly, so that the bottom foam body 1 is not easily locally compressed and dented, thereby strengthening the support effect generated by the reinforcement body 3. The thickness of the reinforcement body 3 is 9.5mm to 10.5mm, preferably 10mm, which has good support strength and a small overall weight.

[0060] In addition, the reinforcement body 3 can also be arranged inside the bottom foam body 1, so that the bottom foam body 1 completely wraps the reinforcement body 3. Compared with the method of embedding the reinforcement body 3 on the upper surface of the bottom foam body 1, this method makes the connection between the reinforcement body 3 and the bottom foam body 1 tighter and more firmly, and can also play a certain role in strengthening support. However, relatively speaking, this method has a more complicated manufacturing process and is more difficult to produce. At the same time, because the reinforcement body 3 does not directly support the carpet 4, after the carpet 4 above the reinforcement body 3 is stepped on, the part of the bottom foam body 1 between the reinforcement body 3 and the carpet 4 will still collapse to a certain extent, affecting the stepping feeling of the occupant.

[0061] The lower structure of the vehicle carpet structure may be exposed at the edge, which may affect the appearance. To solve this problem, the carpet 4 has a free section 401, which is extended outward from the edge of the bottom foam body 1 along the width direction of the vehicle. The free section 401 can shield the structure under the carpet 4, making the appearance of the vehicle carpet structure inside the vehicle more beautiful. The length of the free section 401 is set to 3.5mm to 4.5mm, preferably 4mm, which has a good shielding effect and is not easy to curl due to interference with surrounding objects. The free section 401 can be crimped by the door sill structure in the vehicle, making the edge of the carpet 4 in the vehicle neat and beautiful.

[0062] As a structural optimization of the bottom foam body 1, the two side surfaces of the bottom foam body 1 in the vehicle width direction are constructed as inclined surfaces, which are set to expand outward from the bottom to the top of the bottom foam body 1. The top of the bottom foam body 1 at the inclined surface forms an acute angle, which can better support and stretch the carpet 4 when the carpet 4 is stepped on and shrinks, thereby reducing the shrinkage of the carpet 4. Secondly, the above configuration of the bottom foam body 1 can also reduce the amount of materials used, saving costs while reducing the weight of the entire vehicle.

[0063] Embodiment 2

[0064] Conventional vehicles with slide rails are usually equipped with four long slide rails for the sliding of seats, such as MPV (multi-purpose vehicles) and commercial vehicles. Each slidable seat is connected to two long slide rails, and the four long slide rails can allow all slidable seats to move forward or backward in the X direction of the vehicle. The carpet assembly between adjacent long guide rails and in the movement travel area of ​​the second row of seats will form a narrow and long part. In actual use, this part is prone to collapse due to insufficient support strength. In order to better deal with this situation, this embodiment proposes a vehicle slide rail installation structure.

[0065] In terms of overall structure, the vehicle slide rail installation structure of this embodiment includes a slide rail 5, and a plurality of vehicle carpet structures in the first embodiment are provided on the floor sheet metal, and the vehicle carpet structures are spaced apart along the width direction of the vehicle to form an installation cavity 2 for accommodating the slide rail 5.

[0066] As described above, the vehicle slide rail installation structure described in this embodiment sets the slide rail 5 between adjacent vehicle carpet structures. Because there are a large number of slide rails 5, the carpet 4 structure between adjacent slide rails 5 is relatively narrow and long in shape. By arranging a plurality of the above vehicle carpet structures, the slender vehicle carpet structure can also play a better supporting role for the slide rail 5 and the occupants. Because the two side surfaces of the bottom foam body 1 are inclined surfaces, the longitudinal section of the installation cavity 2 is a trapezoid with a larger bottom, which makes it more convenient to install the slide rail 5 on the floor sheet metal.

[0067] Based on the above overall introduction, refer to Figure 2-Figure 7 Specifically, each vehicle carpet structure can be independently arranged or integrally formed, and it is sufficient to leave the installation cavity 2. In this embodiment, the ends of each vehicle carpet structure in the X direction are integrally formed and connected, and the reinforcement body 3 is arranged between adjacent slide rails 5 and is located in the movement travel area of ​​the second row of seats in the X direction. The carpet 4 in the movement travel area of ​​the second row of seats will form multiple narrow parts due to the arrangement of the guide rails. The narrow and long parts are prone to deformation caused by being stepped on due to their narrow Y-direction width. After the reinforcement body 3 is arranged, the structural strength of this part can be enhanced, so that the carpet 4 is not easily deformed by being stepped on, thereby improving the durability of the carpet 4 and the comfort of the passengers.

[0068] In order to make the connection between the carpet 4 and the slide rail 5 tighter, refer to Figure 4 and Figure 5, flanges 501 are provided on both sides of the top of the slide rail 5, and the flanges 501 can press on the surface of the carpet 4, so that the carpet 4 is less deformed when being stepped on. Secondly, the flanges 501 can cover the edge of the carpet 4, making the junction of the carpet 4 and the slide rail 5 more beautiful. Specifically, in the vehicle height direction, the interference between the edge of the slide rail 5 and the carpet 4 is 2.8mm to 3.2mm, which can not only make the flange 501 press the edge of the carpet 4, but also prevent the flange 501 from over-squeezing the carpet 4 and causing excessive deformation of the surface of the carpet 4. 3mm can be preferably selected as the optimal interference size.

[0069] The carpet 4 will shrink to a certain extent when stepped on, and its edge may be exposed. Therefore, in the width direction of the vehicle, the carpet 4 has a matching section 402 that is pressed under the edge of the slide rail 5. When the passenger steps on the carpet 4, even if the carpet 4 shrinks to a certain extent and a relative displacement occurs between the carpet 4 and the flange 501, the structure under the carpet 4 is not easily exposed, and the appearance is better. Specifically, the side of the matching section 402 close to the middle of the carpet 4 is located between the flange 501 and the bottom foam body, which can make the flange 501 more firmly pressed against the carpet 4. The length of the matching section 402 is 8.5mm to 9.5mm, preferably 9mm.

[0070] In order to improve the connection strength between the bottom foam and the floor sheet metal, refer to Figure 6 and Figure 7 The bottom surface of the bottom foam body 1 is formed with a boss 101 and a pit 102 by foaming. The boss 101 can be inserted into the depression on the floor sheet metal, and the pit 102 can accommodate the protrusion on the floor sheet metal, so that the connection between the bottom foam body 1 and the floor sheet metal is more firmly established.

[0071] When installing the slide rail 5, first install the vehicle carpet structure in place, leaving each installation cavity 2, then install each slide rail 5 into the installation cavity 2, press the flange 501 against the edge of the carpet 4, and smooth the carpet 4.

[0072] The vehicle slide rail installation structure described in this embodiment can improve the supporting strength of the weak and narrow portion of the carpet assembly between adjacent slide rails 5, so that this portion of the corresponding carpet 4 can better support the feet of the occupants when stepped on, thereby improving the comfort of the carpet assembly and the quality of vehicle use.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
