Description

Technical Field

[0001] The present application relates to the technical field of vehicle interior accessories, and in particular to a foot mat carpet fixing assembly and a vehicle. Background Art

[0002] The foot mat is laid on the car carpet, mainly to protect the carpet and keep the car clean. The fixing components between the foot mat and the carpet include a buckle and a foot mat fixing part, wherein the buckle is used to fix with the carpet, and the foot mat fixing part is used to fix with the foot mat, and then the buckle and the foot mat fixing part are fixed.

[0003] The carpet includes a carpet body and a foam layer, and the foam layer is used to provide support for the carpet body. In the prior art, the buckle includes a bottom plate, a bending portion and a buckle portion. The carpet body needs to be processed with corresponding mounting holes through a water cutting or die cutting process, and the foam layer needs to be processed to form a clearance space. The bottom plate is located on one side of the carpet and is used to be fixed with the foot pad fixing portion. After the bending portion and the buckle portion pass through the corresponding mounting holes respectively, the bending portion is bent in the clearance space to be buckled with the buckle portion, thereby achieving fixation between the buckle and the carpet.

[0004] However, such a setting will make the process more complicated and reduce the structural strength of the carpet in the space. It will also affect the NVH (Noise, vibration, and harshness) performance of the entire vehicle, resulting in a poor user experience.

[0005] Therefore, how to provide a floor mat and carpet fixing assembly that can fix the floor mat and carpet while avoiding affecting the supporting strength of the carpet and the NVH performance of the entire vehicle and improving the user experience is a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0006] The purpose of this application is to provide a floor mat and carpet fixing assembly and a vehicle, which can fix the floor mat and the carpet while simplifying the process operation, avoiding affecting the supporting strength of the carpet and the NVH performance of the whole vehicle, and improving the user experience.

[0007] In order to solve the above-mentioned technical problems, the present application provides a foot mat carpet fixing assembly, comprising a first fixing part, a second fixing part and a foot mat fixing part, the first fixing part or the second fixing part is provided with a fixing structure, and the fixing structure is used to be fixed to the foot mat fixing part; the first fixing part comprises a cover part and a first fixing member fixed to each other, the second fixing part comprises a seat part and a second fixing member fixed to each other, the first fixing member is provided with a piercing part, and the piercing part is used to pierce the carpet body, and the first fixing member can be fixed to the second fixing member by plugging.

[0008] Under the action of external force, the piercing portion can directly pierce the complete (i.e., without holes) carpet body, so that the carpet body forms a hole structure corresponding to the piercing portion. Since the hole structure is formed by the piercing portion during the installation process, the carpet body does not need to be processed with installation holes in advance before installing the foot mat carpet fixing assembly. In this way, the process of forming installation holes through water cutting or die cutting can be reduced, effectively reducing costs and improving production efficiency.

[0009] Furthermore, since the first fixing member and the second fixing member are fixed by plugging, that is, during installation, the first fixing part is moved as a whole toward one side of the second fixing part by the tooling, so that the piercing part can pass through the carpet body and the first fixing member and the second fixing member can be plugged and fixed, thereby simplifying the installation operation and improving production efficiency.

[0010] After the first fixing member passes through the hole structure, it can ensure that the outer wall of the first fixing member fits with the inner wall of the hole structure, and the gap between the two is small, which can eliminate the risk of the edge of the carpet hole structure being exposed, improve the product qualification rate, and reduce quality risks. In addition, after the foot mat carpet fixing assembly is fixed to the carpet body, the carpet can be subjected to subsequent processing to form a foaming layer on the surface of the carpet body away from the foot mat, so that the cover or the seat is sandwiched between the foaming layer and the carpet body.

[0011] Since the gap between the first fixing member and the hole structure is small, when the foaming layer is formed on the surface of the carpet body later, there is no need to consider the problem of the foaming agent flowing out along the gap. In addition, since the foaming layer is formed after the foot mat carpet fixing assembly is fixed to the carpet body, there is no need to design a corresponding clearance space for the foaming layer, which can ensure the structural integrity of the foaming layer, ensure the support strength and comfort of the carpet here, and then ensure the NVH performance of the parts and the whole vehicle as well as the pedaling support and comfort.

[0039] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] The present application embodiment provides a foot mat carpet fixing assembly and a vehicle, wherein the vehicle includes Figure 1The carpet 6, foot mat 7 and foot mat carpet fixing assembly shown, the carpet 6 includes a carpet body 61 (i.e., the carpet surface layer of the carpet 6) and a foam layer 62, the foam layer 62 is used to provide support for the carpet body 61, and the foot mat carpet fixing assembly is used to fix the foot mat 7 to the carpet 6 (specifically the carpet body 61).

[0041] like Figure 1-Figure 3 As shown, the foot mat carpet fixing assembly includes a first fixing portion 1, a second fixing portion 2 and a foot mat fixing portion 3, wherein the first fixing portion 1 and the second fixing portion 2 are used to fix to the carpet body 61, the foot mat fixing portion 3 is used to fix to the foot mat 7, and the first fixing portion 1 or the second fixing portion 2 is also provided with a fixing structure 4, and the foot mat 7 can be fixed to the fixing structure 4 to achieve fixation between the foot mat 7 and the carpet 6.

[0042] like Figure 3 and Figure 4 As shown, the first fixing portion 1 includes a cover portion 11 and a first fixing member 12. The first fixing member 12 is fixedly arranged on a side of the cover portion 11 facing the second fixing portion 2. Figure 3 and Figure 5 As shown, the second fixing part 2 includes a seat 21 and a second fixing member 22, and the second fixing member 22 is fixedly arranged on the side of the seat 21 facing the first fixing part 1. The first fixing member 12 is also provided with a piercing portion 13 at one end facing the second fixing part 2, and the piercing portion 13 is used to pierce the carpet body 61. The cross-sectional area of ​​the piercing portion 13 facing the second fixing part 2 is smaller than the cross-sectional area of ​​the side facing the first fixing part 1, so that the piercing portion 13 has a certain piercing ability. Under the action of external force, the piercing portion 13 can directly pierce the complete carpet body 61 (i.e., without a hole), so that the carpet body 61 forms a hole structure corresponding to the piercing portion 13.

[0043] Specifically, before installation, the first fixing part 1 and the second fixing part 2 are located on both sides of the carpet body 61. During installation, the first fixing part 1 is moved as a whole to one side of the second fixing part 2 through the tooling, so that the piercing part 13 can pierce the carpet body 61 and form a corresponding hole structure. Then, as the first fixing part 1 continues to move, the first fixing piece 12 passes through the hole structure of the carpet body 61 and is plugged and fixed with the second fixing piece 22.

[0044] Since the hole structure is formed by piercing the piercing portion 13 during the installation process, the carpet body 61 does not need to be processed with the installation hole in advance before installing the foot mat carpet fixing assembly. In this way, the process of forming the installation hole of the carpet 6 through water cutting or die cutting can be reduced, effectively reducing costs and improving production efficiency.

[0045] Furthermore, since the first fixing member 12 and the second fixing member 22 are fixed by plugging, that is, during installation, the first fixing portion 1 is moved as a whole toward one side of the second fixing portion 2 by the tooling, so that the piercing portion 13 can pass through the carpet body 61 and the first fixing member 12 and the second fixing member 22 can be plugged and fixed, thereby simplifying the installation operation and improving production efficiency.

[0046] After the first fixing member 12 passes through the hole structure, it can ensure that the outer wall of the first fixing member 12 is in contact with the inner wall of the hole structure, and the gap between the two is small, which can eliminate the risk of the edge of the hole structure of the carpet 6 being exposed, improve the product qualification rate, and reduce the quality risk. In addition, after the foot pad carpet fixing assembly is fixed to the carpet body 61, the carpet 6 can be subjected to subsequent processing to form a foaming layer 62 on the side surface of the carpet body 61 away from the foot pad 7. In this way, the cover 11 or the seat 21 is sandwiched between the foaming layer 62 and the carpet body 61.

[0047] It is easy to understand that if the first fixing portion 1 is provided with a fixing structure 4, the seat portion 21 is sandwiched between the foam layer 62 and the carpet body 61, and if the second fixing portion 2 is provided with a fixing structure 4, the cover portion 11 is sandwiched between the foam layer 62 and the carpet body 61 (such as Figure 2 as shown).

[0048] The foaming layer 62 may be a polyurethane foaming layer 621 (i.e., a PU foaming layer), or may be a laminated foaming layer, such as Figure 2 As shown, it includes a polypropylene foam layer 622 (ie, an EPP foam layer) and a polyurethane foam layer 621 .

[0049] Since the gap between the first fixing member 12 and the hole structure is small, when the foaming layer 62 is formed on the surface of the carpet body 61 later, there is no need to consider the problem of the foaming agent flowing out along the gap. In addition, since the foaming layer 62 is formed after the foot mat carpet fixing assembly is fixed to the carpet body 61, there is no need to design a corresponding clearance space for the foaming layer 62, so that the structural integrity of the foaming layer 62 (such as Figure 2 As shown), the support strength and comfort of the carpet 6 are ensured here, thereby ensuring the NVH performance of the parts and the entire vehicle as well as the pedaling support and comfort.

[0050] In this embodiment, the first fixing member 12 and the second fixing member 22 are both cylindrical structures. After the first fixing member 12 passes through the carpet body 61, it can be sleeved and fixed with the second fixing member 22. Of course, in this embodiment, there is no limitation on the specific structure of the first fixing member 12 and the second fixing member 22. For example, the first fixing member 12 can be set as a cylindrical plug, and the second fixing member 22 can be set as a structure with a slot or a jack. After the first fixing member 12 passes through the carpet body 6, it can be inserted into the slot or the jack and fixed with the second fixing member 22. When the first fixing member 12 is set as a cylindrical structure, the piercing portion 13 is a cutting edge arranged along the circumference of the cylindrical structure. After the piercing portion 13 pierces the carpet body 61, it can cut part of the carpet body 61 to form a hole structure, and can ensure the flatness of the carpet body 61 in the area around the hole structure.

[0051] like Figure 3 As shown, when the first fixing member 12 and the second fixing member 22 are sleeved and fixed, the first fixing member 12 is sleeved in the second fixing member 22, and a preset space 5 is formed between the end of the first fixing member 12 and the bottom of the inner cavity of the second fixing member 22. The preset space 5 can be used to place part of the waste cut from the carpet body 61, and also provides enough space for the insertion of the first fixing member 12 and the second fixing member 22 to be suitable for carpet bodies 61 of different thicknesses.

[0052] Furthermore, the first fixing member 12 with the piercing portion 13 is sleeved in the second fixing member 22. The inner diameter of the first fixing member 12 is relatively small, so that the cutting area is small during the piercing process, and the force required for piercing can be reduced. The inner diameter of the second fixing member 22 is relatively large, so that the waste material cut from the carpet body 61 can be completely accommodated, thereby preventing the waste material from interfering with the insertion between the first fixing member 12 and the second fixing member 22.

[0053] The outer wall of the first fixing member 12 is provided with a first protrusion 14 (such as Figure 4 As shown in FIG. 1 , a plurality of second grooves are arranged at intervals along the axial direction on the inner wall of the second fixing member 22. When the first fixing member 12 and the second fixing member 22 are in a fixed state, the first protrusion 14 is located in the second groove and cooperates with the groove wall of the second groove to limit the separation of the first fixing member 12 and the second fixing member 22. With such an arrangement, the structure is relatively simple.

[0054] In addition, the inner wall of the second fixing member 22 is provided with a plurality of second grooves at intervals along the axial direction, and the first protrusion 14 can cooperate with the second protrusion 24 at any position. In this way, the adjustability of the relative position of the first fixing member 12 and the second fixing member 22 can be improved, and the application range is wide, which is suitable for carpet bodies 61 of different thicknesses.

[0055] Furthermore, the number of the first protrusions 14 is also multiple, each first protrusion 14 is arranged along the circumference of the first fixing member 12, and each first protrusion 14 is arranged at intervals along the axial direction of the first fixing member 12, and a first groove is formed between two adjacent first protrusions 14. At the same time, the inner wall of the second fixing member 22 is provided with multiple second protrusions 24 (such as Figure 5 As shown in FIG. 1 ), each second protrusion 24 is arranged along the circumference of the second fixing member 22, and the second groove can be formed between two adjacent second protrusions 24, that is, the second protrusion 24 forms the groove wall of the second groove.

[0056] The bottom diameter of the first groove, the inner diameter of the second protrusion 24, the outer diameter of the first protrusion 14 and the bottom diameter of the second groove increase in sequence. During the installation process, when the first fixing member 12 moves toward one side of the second fixing portion 2, the first protrusion 14 can squeeze the second protrusion 24 when passing through the second protrusion 24 under the action of the tooling, causing the second protrusion 24 to be slightly deformed. After installation in place (that is, after the first fixing member 12 and the second fixing member 22 are fixed), at least part of the first protrusion 14 is located in the second groove, and at least part of the second protrusion 24 is located in the first groove. The abutment between the first protrusion 14 and the second protrusion 24 ensures the stability between the first fixing member 12 and the second fixing member 22 to prevent the two from separating.

[0057] The arrangement of multiple first protrusions 14 and multiple second protrusions 24 enables the first fixing member 12 and the second fixing member 22 to have a certain degree of adjustability in the axial direction. Specifically, during the installation process, when the first fixing member 12 pierces the carpet body 61 and is fixed to the second fixing member 22, it is ensured that part of the first protrusion 14 is located in the second groove, part of the second protrusion 24 is located in the first groove, and part of the first protrusion 14 and the second protrusion 24 can interfere with each other. There is no limit to the number of the first protrusion 14 and the second protrusion 24 that interfere. Therefore, the length of the first fixing member 12 and the second fixing member 22 for fixing does not need to be precisely designed, and can be applicable to carpet bodies 61 of different thicknesses, with good flexibility.

[0058] In addition, a plurality of first protrusions 14 and a plurality of second protrusions 24 are respectively provided, and the number of first protrusions 14 and second protrusions 24 that cooperate and interfere with each other is also multiple, so that even if one or some of the first protrusions 14 or the second protrusions 24 are damaged, the fixing stability of the first fixing member 12 and the second fixing member 22 can be guaranteed.

[0059] Specifically, in this embodiment, there is no limitation on the structural shapes of the first protrusion 14 and the second protrusion 24. For example, the cross-sections of the first protrusion 14 and the second protrusion 24 can be set to be square, triangle or other shapes.

[0060] The first protrusion 14 and the second protrusion 24 can also be configured as barbed protrusions, the outer diameter of the first protrusion 14 and the inner diameter of the second protrusion 24 are both gradually reduced from bottom to top, a barbed groove is formed between two adjacent barbed protrusions, and when the first fixing member 12 and the second fixing member 22 are in a fixed state, the barbed protrusions are located in the barbed grooves, and the groove walls of the barbed grooves limit the barbed protrusions to prevent the first fixing member 12 from being separated from the second fixing member 22. Among them, "upper" refers to the side facing the second fixing portion 2, and "lower" refers to the side facing the first fixing portion 1.

[0061] Alternatively, the outer wall surface of the first fixing member 12 may be provided with a first protrusion segment and a first cylindrical segment along the circumferential direction, wherein the first protrusion segment is provided with a plurality of first protrusions 14 along the axial direction, and the inner wall surface of the second fixing member 22 is also provided with a second protrusion segment and a second cylindrical segment along the circumferential direction, and the second protrusion segment is provided with a second protrusion 24 along the axial direction, and both the first cylindrical segment and the second cylindrical segment are cylindrical structures. During installation, the first protrusion segment is corresponded to the second cylindrical segment, and the second protrusion segment is axially inserted into the first cylindrical segment accordingly. After being inserted into place, the first fixing part 1 and the second fixing part 2 are relatively rotated so that the first protrusion segment and the second protrusion segment correspond, and the first protrusion 14 and the second protrusion 24 cooperate to limit the first fixing member 12 and the second fixing member 22 from disengaging.

[0062] The first fixing member 12 and the second fixing member 22 are directly installed in place by press-fitting, and there is no need to rotate the first fixing part 1 or the second fixing part 2 later, which can simplify the installation operation and avoid the carpet body 61 from twisting at the hole structure, thereby ensuring the flatness of the carpet body 61. It can also avoid the first fixing part 1 and the second fixing part 2 from rotating relative to each other due to vibration and other reasons during later use, resulting in the first fixing member 12 and the second fixing member 22 being separated, thereby achieving better stability.

[0063] In this embodiment, at least one of the end of the second fixing member 22 and the edge of the seat 21 is provided with an extension protrusion 25 along the circumferential direction, and when the first fixing member 12 and the second fixing member 22 are fixed, the extension protrusion 25 can be pressed against the carpet body 61. Specifically, the end of the second fixing member 22 is provided with an extension protrusion 25 along the circumferential direction (such as Figure 3 As shown), the edge of the seat portion 21 may also be provided with an extending protrusion 25 along the circumferential direction, or the end of the second fixing member 22 and the edge of the seat portion 21 may be provided with an extending protrusion 25 respectively.

[0064] And, if Figure 3 As shown, the extended protrusion 25 provided at the end of the second fixing member 22 can also provide stable support for the carpet body 61 during the installation process, thereby preventing the carpet body 61 from moving toward the inner cavity of the second fixing member 22 along with the piercing portion 13, thereby providing auxiliary effect on the piercing and cutting of the piercing portion 13 and ensuring smooth installation.

[0065] The extended protrusion 25 is set toward one side of the first fixing portion 1 and is arranged along the circumference of the hole structure. When the extended protrusion 25 is pressed against the carpet body 61, it can further achieve sealing in the circumference of the hole structure to avoid the edge of the hole structure from being exposed, thereby improving the product qualification rate and reducing quality risks. At the same time, it can also avoid the foaming agent from being exposed when the foaming layer 62 is formed on the surface of the carpet body 61 later.

[0066] The thickness of the end of the extending protrusion 25 is smaller than the thickness of the side of the extending protrusion 25 facing the second fixing portion 2 . This configuration can further ensure the contact stability between the extending protrusion 25 and the carpet body 61 .

[0067] Specifically, in this embodiment, there is no limitation on the specific structure of the extending protrusion 25 , which can be formed by processing or by a flanging structure.

[0068] A reinforcing rib 23 is further provided between the seat portion 21 and the second fixing member 22 along the circumference of the second fixing member 22 , so as to ensure the bonding strength between the seat portion 21 and the second fixing member 22 .

[0069] like Figure 3 , Figure 5 and Figure 6 As shown, the second fixing member 22 is provided with an extension portion extending to a side away from the first fixing portion 1 . The extension portion is located on a side surface of the seat portion 21 away from the first fixing portion 1 and forms a fixing structure 4 for fixing to the foot pad fixing portion 3 .

[0070] Of course, in this embodiment, the specific structure of the fixing structure 4 is not limited. For example, the fixing structure 4 may be provided separately on the surface of the side of the seat 21 away from the first fixing part 1, or the fixing structure 4 may be provided on the side of the first fixing part 1 away from the second fixing part 2. When the fixing structure 4 is formed by extending the second fixing member 22, Figure 3 , Figure 5 and Figure 6 As shown, the fixing structure 4 has an inner cavity structure and is connected to the inner cavity of the second fixing member 22, which can extend the length of the second fixing member 22 and extend the matching length of the first fixing member 12 and the second fixing member 22 within a limited space. In other words, while ensuring the fixing stability, the axial length and the overall volume of the second fixing part 2 can be reduced, which is conducive to miniaturization.

[0071] Specifically, the method of fixing the fixing structure 4 and the foot pad fixing portion 3 is not specifically limited in this embodiment. Figure 1As shown, the outer wall of the fixing structure 4 is provided with a slot 41 along the circumferential direction, the foot pad fixing part 3 is provided with a receiving cavity 31, and the cavity wall of the receiving cavity 31 is provided with a locking protrusion 32. During installation, the end of the fixing structure 4 is inserted into the receiving cavity 31, and the locking protrusion 32 cooperates with the slot 41 to limit the position, so that the fixing structure 4 and the foot pad fixing part 3 can be fixed.

[0072] Furthermore, in this embodiment, the specific structure of the foot pad fixing portion 3 and how to fix it to the foot pad 7 are already well-known prior art to those skilled in the art, and will not be described in detail here to save space.

[0073] like Figure 3 As shown, a surface of the carpet body 61 on one side facing the foot pad 7 is further provided with a mounting groove 611 adapted to the foot pad carpet fixing assembly. The foot pad carpet fixing assembly is installed in the mounting groove 611, and the second fixing portion 2 is at least partially located in the mounting groove 611, so that when the foot pad 7 is not installed, the height of the second fixing portion 2 protruding from the surface of the carpet body 61 is reduced (or even not protruding at all), thereby ensuring the flatness of the carpet body 61 before the foot pad 7 is installed, thereby improving comfort and aesthetics.

[0074] Figure 3 The carpet body 61 is shown as a schematic diagram of the structure of the assembly in the fixed state with the first fixing part 1 and the second fixing part 2. The first fixing part 1, the second fixing part 2 and the carpet body 61 are fixed by the first fixture 81 and the second fixture 82. In order to ensure smooth installation and avoid deformation of the first fixing part 1 and the second fixing part 2 during installation, the structure of the installation surface of the first fixture 81 is Figure 3 The structure of the surface of the component facing the second fixing portion 2 is adapted, and the mounting surface of the second tooling 82 is adapted to the Figure 3 The structure of the surface of the assembly far from the second fixing part 2 is adapted to each other. That is to say, the mounting surface of the first fixture 81 is provided with a positioning structure adapted to the first fixing part 1, and the mounting surface of the second fixture 82 is provided with a positioning structure adapted to the second fixing part 2 and the carpet 6. Through the coordinated installation of the positioning structures, the coaxiality of the first fixing member 12 and the second fixing member 22 in the installed state can be ensured, thereby ensuring the accuracy of the later installation and fixation.

[0075] The process of fixing the foot mat carpet fixing assembly provided in this embodiment to the carpet body 61 through the tooling is as follows:

[0076] (1) The first fixing part 1 is vacuum-adsorbed onto the mounting surface of the first fixture 81 through the gas path 83 of the fixture, and the second fixing part 2 and the carpet body 61 are vacuum-adsorbed onto the mounting surface of the second fixture 82 through the gas path 83 of the fixture, respectively. Figure 7As shown, the second fixing portion 2 is located on a side of the carpet body 61 away from the first fixing portion 1;
