Description

Technical Field

[0001] This application relates to the field of vehicle interior technology, and in particular to a gap-blocking structure and a vehicle. Background Technology

[0002] The steering column is the core component of a car's steering system. It connects the steering wheel and the steering gear, is responsible for transmitting the driver's steering actions and turning the vehicle, and also has key functions such as energy absorption protection, position adjustment, and anti-theft locking.

[0003] Steering columns are typically fitted with steering column covers, which are mounted on the steering column and located at the instrument panel to conceal the lower structure of the steering column. However, the steering column cover needs to be adjusted in position to fit the steering column, and there is a significant gap between the steering column cover and the instrument panel. This results in the steering column cover not completely concealing the internal structure of the instrument panel, which is detrimental to improving the concealment effect. Utility Model Content

[0004] In view of this, this application aims to propose a gap shielding structure to improve the shielding effect on the internal structure of the dashboard.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A gap shielding structure includes an inner peripheral frame and an outer peripheral frame arranged around a steering column, and a curtain connected between the inner peripheral frame and the outer peripheral frame. The inner peripheral frame is detachably connected to the steering column cover, and the outer peripheral frame is detachably connected to the instrument panel frame. The curtain can cover the gap between the steering column cover and the instrument panel frame.

[0006] Furthermore, the inner circumferential skeleton is snapped into connection with the steering column cover along the axial direction of the steering column.

[0007] Furthermore, a first positioning structure and a first snap-fit ​​structure are provided between the inner circumferential frame and the steering column cover. The first positioning structure is used to define the relative installation position of the inner circumferential frame and the steering column cover, and the inner circumferential frame and the steering column cover are snap-fitted together by the first snap-fit ​​structure.

[0008] Furthermore, the first snap-fit ​​structure includes a plurality of one-way snap-fit ​​structures disposed between the inner circumferential frame and the steering column guard, the plurality of one-way snap-fit ​​structures being arranged at intervals around the steering column guard, and each one-way snap-fit ​​structure having a different snap-fit ​​direction. The first snap-fit ​​structure includes a bidirectional snap-fit ​​structure disposed between the inner circumferential frame and the steering column guard. The bidirectional snap-fit ​​structure is disposed on the side of the steering column guard facing the front of the vehicle, and the snap-fit ​​direction of the bidirectional snap-fit ​​structure is along the radial direction of the steering column.

[0009] Furthermore, the inner circumferential skeleton is integrally formed.

[0010] Furthermore, the outer peripheral skeleton is integrally formed.

[0011] Furthermore, the curtain includes a first cylindrical part, a connecting part, and a second cylindrical part connected in sequence. The second cylindrical part is sleeved outside the first cylindrical part. The end of the first cylindrical part away from the connecting part is connected to the inner peripheral frame, and the end of the second cylindrical part away from the connecting part is connected to the outer peripheral frame.

[0012] Furthermore, the outer peripheral frame is mounted on the instrument panel frame via a mounting bracket along the lower part of the vehicle's vertical direction. The mounting bracket is detachably connected to the outer peripheral frame and the instrument panel frame.

[0013] Furthermore, the curtain is made of a soft material.

[0014] Furthermore, the curtain is integrally formed.

[0015] Furthermore, the steering column cover includes a first half-cover and a second half-cover, which are detachably connected to form a through hole for the steering column to pass through.

[0016] Furthermore, a second positioning structure and a second snap-fit ​​structure are provided between the first half-cover and the second half-cover. The second positioning structure can limit the relative installation position of the first half-cover and the second half-cover, and the first half-cover and the second half-cover are snap-fitted together by the second snap-fit ​​structure.

[0017] Compared with related technologies, this application has the following advantages: (1) The gap shielding structure described in this application, by setting an inner peripheral skeleton connecting the steering column cover and an outer peripheral skeleton connecting the instrument panel skeleton, and connecting a curtain between the inner peripheral skeleton and the outer peripheral skeleton, can seal the gap between the instrument panel and the steering column cover, which is beneficial to improving the shielding effect on the internal structure of the instrument panel. The curtain can prevent external debris from entering the instrument panel through the gap and can also play a sound insulation role. At the same time, the detachable connection between the inner peripheral skeleton and the steering column cover, and the outer peripheral skeleton and the instrument panel skeleton can improve the convenience of assembly and maintenance, and help reduce maintenance costs.

[0018] (2) Setting the inner circumferential skeleton and the steering column cover to be connected by snap-fit ​​can simplify the assembly process between the two and facilitate disassembly during later maintenance.

[0019] (3) Setting the first positioning structure can make the connection position between the inner circumferential skeleton and the steering column cover more accurate, reduce the assembly difficulty and reduce the assembly error. Setting the first snap-fit ​​structure can improve the assembly convenience between the inner circumferential skeleton and the steering column cover and improve the assembly efficiency.

[0020] (4) Multiple one-way snap-fit ​​structures have multiple snap-fit ​​directions and are arranged around the steering column, which can form a full circumferential fixation between the inner circumferential skeleton and the steering column guard. They have good connection strength in all directions. At the same time, the two-way snap-fit ​​structure in front of the steering column can still provide space for the steering column guard to move relative to the inner circumferential skeleton after snap-fitting, which is conducive to aligning and installing the one-way snap-fit ​​structure.

[0021] (5) The inner circumferential skeleton is integrally formed, which has good overall structural strength, can reduce the number of parts and simplify the assembly process, and reduce the accumulation of dimensional tolerances and assembly errors that may be caused by the assembly of multiple parts, which is conducive to improving production efficiency and reducing manufacturing costs; the outer circumferential skeleton is integrally formed, which has good overall structural strength, can reduce the number of parts and simplify the assembly process, and reduce the accumulation of dimensional tolerances and assembly errors that may be caused by the assembly of multiple parts, which is conducive to improving production efficiency and reducing manufacturing costs.

[0022] (6) The curtain adopts a structure in which the first cylindrical part and the second cylindrical part are nested together and connected by a connecting part. The connecting part can deform and adapt when the first cylindrical part moves relative to the second cylindrical part, so that the curtain can deform accordingly when the position of the steering column is adjusted, always maintaining effective shielding and helping to maintain the gap sealing effect. A mounting bracket that can be detachably connected between the instrument panel frame and the outer peripheral frame is provided, which can form an operating channel for the installation and removal of the steering column without installing the mounting bracket, without having to remove the entire outer peripheral frame, which helps to improve maintenance convenience.

[0023] (7) The curtain made of soft material has good flexibility, can fit adjacent parts well, can better adapt to the position adjustment of the steering column, and will not produce dry friction noise. It also has good sound insulation effect and a long service life. The one-piece molding of the curtain can make the curtain seamless and have a one-piece effect, which is conducive to improving the appearance quality of the area.

[0024] (8) The steering column cover is designed as a detachable first half cover and second half cover, which can be assembled from both sides after the steering column is installed. The assembly is relatively simple. At the same time, when repairing the steering column or related components, the internal structure can be exposed by simply removing the first half cover and the second half cover, which helps to improve the convenience of maintenance.

[0025] (9) Setting a second positioning structure can make the connection position between the first half cover and the second half cover more accurate, reduce assembly difficulty and reduce assembly error. Setting a second snap-fit ​​structure can improve the ease of assembly between the first half cover and the second half cover. It not only helps to improve assembly efficiency, but also avoids the use of visible screws, which helps to improve the aesthetics of the appearance.

[0026] Another object of this application is to provide a vehicle having the aforementioned gap-blocking structure.

[0027] The vehicle described in this application, by having the aforementioned gap-blocking structure, allows the curtain to cover the gap between the steering column cover and the dashboard, thus better concealing the structure inside the dashboard and enhancing the sense of refinement in the interior. It also improves the isolation performance between the dashboard interior and the passenger compartment, which is beneficial for improving the vehicle's cabin sealing, NVH (Noise, Vibration, Harshness) performance, and dustproof capabilities. Furthermore, the detachable connection between the inner circumferential frame and the steering column cover, and the detachable connection between the outer circumferential frame and the dashboard frame, reduces assembly and maintenance time costs and improves vehicle maintainability.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0034] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0035] An embodiment of the first aspect of this application provides a gap-blocking structure that is beneficial for improving the blocking effect on the internal structure of the dashboard.

[0036] The steering column is the core component of a car's steering system. It connects the steering wheel and the steering gear, is responsible for transmitting the driver's steering actions and turning the vehicle, and also has key functions such as energy absorption protection, position adjustment, and anti-theft locking.

[0037] In related technologies, the steering column is usually equipped with a steering column cover, which is mounted on the steering column and located in the dashboard to cover the lower structure of the steering column. However, in order to provide a comfortable grip position for people of different heights, some vehicles have an adjustable steering wheel. When using the adjustment function, the position of the steering column needs to be adjusted to change the position of the steering wheel.

[0038] Correspondingly, when the steering column is adjusted, the steering column cover needs to be adjusted accordingly. This results in a large gap between the steering column cover and the instrument panel, and the steering column cover cannot completely cover the internal structure of the instrument panel, which is not conducive to improving the covering effect.

[0039] In view of this, in order to overcome the shortcomings of related technologies, the gap blocking structure in this embodiment combines... Figure 1 and Figure 2As shown, the overall design includes an inner peripheral frame 1 and an outer peripheral frame 2 surrounding the steering column, as well as a curtain 3 connecting the inner peripheral frame 1 and the outer peripheral frame 2.

[0040] The inner peripheral frame 1 is detachably connected to the steering column cover 4, the outer peripheral frame 2 is detachably connected to the instrument panel frame, and the curtain 3 can cover the gap between the steering column cover 4 and the instrument panel frame.

[0041] Therefore, by setting the inner peripheral frame 1 that connects the steering column cover 4 and the outer peripheral frame 2 that connects the instrument panel frame, and connecting the curtain 3 between the inner peripheral frame 1 and the outer peripheral frame 2, the gap between the instrument panel and the steering column cover 4 can be sealed, which helps to improve the shielding effect on the internal structure of the instrument panel, and the curtain 3 can prevent external debris from entering the instrument panel through the gap.

[0042] Secondly, the curtain 3 seals the gap between the steering column cover 4 and the instrument panel, providing sound insulation and improving the vehicle's NVH performance, as well as enhancing the cabin's sealing and comfort. Furthermore, the detachable connections between the inner frame 1 and the steering column cover 4, and between the outer frame 2 and the instrument panel frame, improve the ease of assembly and maintenance of these components, thus reducing maintenance costs.

[0043] Based on the above overview, specifically, the outer frame 2 is connected to the instrument panel, and the steering column cover 4 extends outward from the outer frame 2. One end of the steering column extends out of the steering column cover 4 and connects to the steering wheel. When adjusting the position of the steering wheel, for example, by moving the steering wheel with your hands, the steering column and steering column cover 4 will move with the steering wheel, and the curtain 3 will always be positioned between the instrument panel and the steering column cover 4.

[0044] Continue to combine Figure 1 and Figure 2 As shown, in some exemplary embodiments, the inner circumferential frame 1 is snap-fitted to the steering column guard 4 along the axial direction of the steering column. The axial direction of the steering column is the direction of extension of the steering column centerline a.

[0045] In this way, the inner circumferential skeleton 1 and the steering column cover 4 are connected by a snap-fit ​​mechanism. When it is necessary to connect the inner circumferential skeleton 1 and the steering column cover 4, simply lift the inner circumferential skeleton 1 upward along the axial direction of the steering column centerline a, and the inner circumferential skeleton 1 will snap onto the steering column cover 4. This simplifies the assembly process between the inner circumferential skeleton 1 and the steering column cover 4, and facilitates disassembly during later maintenance.

[0046] Of course, the inner circumferential frame 1 and the steering column cover 4 can also be connected by means such as bolts or adhesives, but these connection methods will reduce the detachability of the inner circumferential frame 1, which is not conducive to later maintenance.

[0047] Reference Figures 3 to 5 Based on the snap-fit ​​connection between the inner circumferential frame 1 and the steering column cover 4, in some exemplary embodiments, a first positioning structure and a first snap-fit ​​structure are provided between the inner circumferential frame 1 and the steering column cover 4. The first positioning structure is used to define the relative installation position of the inner circumferential frame 1 and the steering column cover 4, and the inner circumferential frame 1 and the steering column cover 4 are snap-fit ​​connected through the first snap-fit ​​structure.

[0048] In this way, the first positioning structure ensures a more accurate connection between the inner circumferential frame 1 and the steering column cover 4. During assembly, the first positioning structure acts as a guide, reducing assembly difficulty and errors. The first snap-fit ​​structure also improves the ease of assembly between the inner circumferential frame 1 and the steering column cover 4, enhancing overall assembly efficiency compared to traditional bolt or adhesive connections.

[0049] Furthermore, based on the first snap-fit ​​structure provided between the inner circumferential frame 1 and the steering column cover 4, in some exemplary embodiments, the first snap-fit ​​structure includes multiple one-way snap-fit ​​structures provided between the inner circumferential frame 1 and the steering column cover 4. The multiple one-way snap-fit ​​structures are arranged at intervals around the steering column cover 4, and the snap-fit ​​direction of each one-way snap-fit ​​structure is different.

[0050] Meanwhile, the first snap-fit ​​structure also includes a bidirectional snap-fit ​​structure located between the inner circumferential frame 1 and the steering column cover 4. The bidirectional snap-fit ​​structure is located on the side of the steering column cover 4 facing the front of the vehicle, and the snap-fit ​​direction of the bidirectional snap-fit ​​structure is along the radial direction of the steering column, that is, the direction perpendicular to the central axis a of the steering column.

[0051] As set up above, multiple one-way snap-fit ​​structures have multiple snap-fit ​​directions and are arranged around the steering column, which can form a full circumferential fixation between the inner circumferential skeleton 1 and the steering column cover 4, and have good connection strength in all directions. At the same time, the two-way snap-fit ​​structure in front of the steering column can still provide space for the steering column cover 4 to move relative to the inner circumferential skeleton 1 after snap-fit, which is conducive to aligning and installing the one-way snap-fit ​​structure.

[0052] It's worth noting that, generally speaking, for a snap-fit ​​structure to achieve the snap-fit ​​effect, it needs a buckle with a convex head and a slot in the form of a groove or through hole. The snap-fit ​​direction corresponding to a two-way snap-fit ​​structure and a one-way snap-fit ​​structure refers to the direction of movement of the buckle head when it snaps into the slot. A one-way snap-fit ​​structure buckle has one head; a two-way snap-fit ​​structure buckle has two heads, and the two heads move in opposite directions when they snap into the slot.

[0053] Reference Figure 2 and Figure 3 In a preferred embodiment, the first snap-fit ​​structure between the inner circumferential skeleton 1 and the steering column cover 4 is symmetrically arranged about the steering column centerline a along the left-right direction of the vehicle, and the first positioning structure is also symmetrically arranged about the steering column centerline a along the left-right direction of the vehicle. Figure 3 The image shows the first snap-fit ​​structure and the first positioning structure on one side after the inner circumferential frame 1 is connected to the steering column cover 4.

[0054] The first positioning structure includes a first positioning post 101 and a first positioning hole 404. The first positioning post 101 is disposed on the inner peripheral frame 1, and the first positioning hole 404 is disposed on the steering column cover 4. The first positioning post 101 is inserted into the first positioning hole 404 to achieve positioning between the inner peripheral frame 1 and the steering column cover 4. The first positioning post 101 can be configured as having a cross-shaped cross section, and a chamfer can be provided at the free end of the first positioning post 101 to facilitate the insertion of the first positioning post 101 into the first positioning hole 404.

[0055] In the first snap-fit ​​structure, three unidirectional snap-fit ​​structures can be arranged on each side after the inner circumferential frame 1 is connected to the steering column cover 4. Each unidirectional snap-fit ​​structure includes a first unidirectional buckle 102 and a first unidirectional slot 405. The first unidirectional buckle 102 is located on the inner circumferential frame 1, and the first unidirectional slot 405 is located on the steering column cover 4. The snap-fit ​​directions of the first unidirectional buckles 102 in the three unidirectional snap-fit ​​structures are all different. In addition, the bidirectional snap-fit ​​structure in the first snap-fit ​​structure includes a bidirectional buckle 103 and a bidirectional slot 406. The bidirectional buckle 103 is located on the inner circumferential frame 1, and the bidirectional slot 406 is located on the steering column cover 4.

[0056] It should be noted that, in order to facilitate the installation between the inner circumferential frame 1 and the steering column cover 4, a pre-set clearance can be made between the first positioning post 101 and the first positioning hole 404, and a pre-set clearance can also be made between the bidirectional snap-fit ​​103 and the bidirectional slot 406. In this way, when connecting the inner circumferential frame 1 and the steering column cover 4, the first positioning structure can be aligned first, and then the bidirectional snap-fit ​​structure can be snapped into place. At this time, the unidirectional snap-fit ​​structure is not yet snapped into place. The clearance left by the first positioning structure and the bidirectional snap-fit ​​structure can be used to adjust the position of the first unidirectional snap-fit ​​102 to ensure that the first unidirectional snap-fit ​​102 can be smoothly snapped into the first unidirectional slot 405.

[0057] See Figure 2 and Figure 5 In some exemplary embodiments, the inner circumferential skeleton 1 is integrally molded. This integral molding of the inner circumferential skeleton 1 provides better overall structural strength, reduces the number of parts and simplifies assembly processes, and reduces the accumulation of dimensional tolerances and assembly errors that may result from assembling multiple parts, thus improving production efficiency and reducing manufacturing costs. The inner circumferential skeleton 1 can be made of plastic.

[0058] See Figure 2 and Figure 6 In some exemplary embodiments, the outer peripheral frame 2 is integrally molded. Therefore, the integral molding of the outer peripheral frame 2 provides better overall structural strength, reduces the number of parts and simplifies assembly processes, and reduces the accumulation of dimensional tolerances and assembly errors that may result from assembling multiple parts, thus improving production efficiency and reducing manufacturing costs. The outer peripheral frame 2 can be made of plastic.

[0059] Reference Figure 1 , Figure 2 and Figure 7 In some exemplary embodiments, the curtain 3 includes a first cylindrical portion 301, a connecting portion 302, and a second cylindrical portion 303 connected in sequence. The second cylindrical portion 303 is sleeved outside the first cylindrical portion 301. One end of the first cylindrical portion 301 away from the connecting portion 302 is connected to the inner peripheral frame 1, and one end of the second cylindrical portion 303 away from the connecting portion 302 is connected to the outer peripheral frame 2.

[0060] With this configuration, the curtain 3 adopts a structure in which the first cylindrical part 301 and the second cylindrical part 303 are nested together and connected by the connecting part 302. The connecting part 302 can deform and adapt when the first cylindrical part 301 moves relative to the second cylindrical part 303, so that the curtain 3 can deform with the steering column cover 4 when the position of the steering column is adjusted, always maintaining effective shielding of the gap between the steering column cover 4 and the instrument panel, and helping to maintain the sealing effect of the gap.

[0061] Continue to refer to Figure 1 , Figure 2 and Figure 7 In some exemplary embodiments, the curtain 3 is made of a soft material. This design allows the soft material curtain 3 to be more flexible, conforming better to adjacent components and adapting more readily to steering column position adjustments. It also prevents dry friction noise, provides good sound insulation, and has a longer service life. The material of the curtain 3 can be, for example, rubber, fabric, or leather, all common soft materials used in vehicles.

[0062] Regarding the connection method between the curtain 3 and the inner and outer circumferential frames 1 and 2, when the curtain 3 is made of rubber, it can be directly vulcanized and bonded to the inner and outer circumferential frames 1 and 2, forming a single unit. When the curtain 3 is made of fabric or leather, it can be bonded to the inner and outer circumferential frames 1 and 2, forming a single unit for easy assembly. Alternatively, as a preferred embodiment, a portion of the curtain 3 can be pressed between the outer circumferential frame 2 and the instrument panel, or between the inner circumferential frame 1 and the steering column cover 4, to improve the positional stability of the curtain 3.

[0063] Still refer to Figure 1 , Figure 2 and Figure 7 In some exemplary embodiments, the curtain 3 is integrally molded. This integral molding of the curtain 3 creates a seamless, one-piece effect, which improves the overall appearance and enhances the vehicle's refined look.

[0064] Reference Figure 1 , Figure 2 and Figure 6 As shown, in some exemplary embodiments, the outer peripheral frame 2 is mounted on the instrument panel frame via a mounting bracket 5 along the lower part of the vehicle in the vertical direction. The mounting bracket 5 is detachably connected to the outer peripheral frame 2 and the instrument panel frame.

[0065] This configuration allows the mounting bracket 5 to support the outer frame 2, improving its stability and preventing the instrument panel from collapsing or deforming. The mounting bracket 5 is detachably connected between the instrument panel frame and the outer frame 2, creating an operating channel between them when the bracket is not installed. This channel allows for the installation and removal of the steering column without completely dismantling the outer frame 2, improving maintenance convenience. After the steering column is installed, the mounting bracket 5 is then installed between the instrument panel frame and the outer frame 2, providing further support for the outer frame 2.

[0066] The mounting bracket 5 can be connected to the instrument panel frame by bolts, and a clip 6 and a screw 7 can be provided between the mounting bracket 5 and the outer peripheral frame 2. The clip 6 is attached to the mounting bracket 5, and the threaded end of the screw 7 passes through the outer peripheral frame 2 and is threadedly connected to the clip 6, thereby fixing the mounting bracket 5 to the outer peripheral frame 2.

[0067] Furthermore, to further enhance the stability of the outer peripheral frame 2 on the instrument panel, a support leg 201 can be provided on the outer peripheral frame 2. The support leg 201 is located on the opposite side of the outer peripheral frame 2 from the mounting bracket 5, and is connected to the instrument panel frame. In this way, the support leg 201 can stably support the outer peripheral frame 2. The connection between the support leg 201 and the instrument panel frame can be, for example, a bolt connection.

[0068] Reference Figure 2 , Figures 8 to 10 As shown, in some exemplary embodiments, the steering column cover 4 includes a first half-cover 401 and a second half-cover 402, which are detachably connected to form a through hole 403 through which the steering column passes.

[0069] In this embodiment, the steering column cover 4 is designed as a detachable first half cover 401 and a second half cover 402, which can be assembled from both sides after the steering column is installed, making assembly relatively simple. At the same time, when repairing the steering column or related components, the internal structure can be exposed simply by removing the two half covers, which helps to improve the convenience of maintenance.

[0070] As for the specific split form of the steering column cover 4, it can be split along the left-right direction of the vehicle or split along the up-down direction of the vehicle. It is preferred to adopt the form of split along the up-down direction of the vehicle, so that the seam of the steering column cover 4 will not be directly exposed in the driver's field of vision, and has a better appearance quality.

[0071] Regarding the arrangement of the first half-cover 401 and the second half-cover 402, the first half-cover 401 can be placed on the upper side of the steering column, and the second half-cover 402 can be placed on the lower side of the steering column. The materials of the first half-cover 401 and the second half-cover 402 can be, for example, PP (polypropylene) + EPDM (ethylene propylene diene monomer rubber) + TD20 (20% talc). It is a modified material with PP as the matrix, EPDM for toughening and TD20 for filling, which has a good balance in terms of mechanical properties, environmental protection, weather resistance, processability and cost-effectiveness.

[0072] In addition, the first half-cover 401 and the second half-cover 402 also form two first hole structures 407, which are used for the light control lever or the wiper lever. The second half-cover 402 is also provided with a second hole structure 4023 and a third hole structure 4024. The second hole structure 4023 is used to arrange the steering wheel adjustment switch, and the third hole structure 4024 is used for bolts to be inserted to fix the steering column.

[0073] Continue to refer to Figure 2 , Figures 8 to 10 As shown, based on the detachable connection between the first half-cover 401 and the second half-cover 402, in some exemplary embodiments, a second positioning structure and a second snap-fit ​​structure are provided between the first half-cover 401 and the second half-cover 402. The second positioning structure can define the relative installation position of the first half-cover 401 and the second half-cover 402, and the first half-cover 401 and the second half-cover 402 are snap-fitted together by the second snap-fit ​​structure.

[0074] Thus, the second positioning structure enables the connection position between the first half-cover 401 and the second half-cover 402 to be more accurate, and reduces assembly difficulty and assembly error. The second snap-fit ​​structure can improve the ease of assembly between the first half-cover 401 and the second half-cover 402, which not only helps to improve assembly efficiency, but also avoids the use of visible screws, and helps to improve the aesthetics of the appearance.

[0075] In some embodiments, the second positioning structure includes a second positioning post 4011 and a second positioning hole 4021. The second positioning post 4011 is disposed on the first half-cover 401, and the second positioning hole 4021 is disposed on the second half-cover 402. The second positioning post 4011 passes through the second positioning hole 4021 to achieve positioning between the first half-cover 401 and the second half-cover 402. The second snap-fit ​​structure includes a second one-way snap fastener 4012 and a second one-way slot 4022. The second one-way snap fastener 4012 is disposed on the first half-cover 401, and the second one-way slot 4022 is disposed on the second half-cover 402. The second one-way snap fastener 4012 snaps into the second one-way slot 4022 to achieve snap-fit ​​connection between the first half-cover 401 and the second half-cover 402.

[0076] Preferably, multiple second snap-fit ​​structures can be provided, and the snap-fit ​​direction of the second unidirectional snap fastener 4012 of each second snap-fit ​​structure is different. The number of second positioning structures can be adjusted according to the position and number of the second snap-fit ​​structures, as long as a second positioning structure is provided next to each second snap-fit ​​structure. The number of second snap-fit ​​structures can be, for example, six, eight, ten, etc.

[0077] The assembly steps of the gap shielding structure of this application are as follows: first, the outer peripheral frame 2 is installed on the instrument panel frame along the axial direction of the steering column; then, the steering column cover 4 is installed on the steering column; finally, the inner peripheral frame 1 is lifted and installed on the steering column cover 4, so that the curtain 3 can shield the gap between the steering column cover 4 and the instrument panel.

[0078] It is worth noting that, regarding the gap-blocking structure of this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still [structured using...]. Figures 1 to 10 As shown, it may include, for example, an outer frame 2, a curtain 3, an inner frame 1, a steering column cover 4, a mounting bracket, etc.

[0079] The curtain 3 is made of leather and is bonded between the inner frame 1 and the outer frame 2.

[0080] The outer peripheral frame 2 is detachably connected to the instrument panel frame, and the inner peripheral frame 1 is snap-fitted to the steering column cover 4.

[0081] The steering column cover 4 includes an upper first half cover 401 and a lower second half cover 402, which are snapped together.

[0082] The mounting bracket is detachably connected between the instrument panel frame and the outer peripheral frame 2.

[0083] In the preferred embodiment of the above gap shielding structure, the specific settings and arrangements of the outer peripheral frame 2, curtain 3, inner peripheral frame 1, steering column guard 4, mounting bracket, etc., can still be referred to the descriptions in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the outer peripheral frame 2, curtain 3, inner peripheral frame 1, steering column guard 4, and mounting bracket, etc., can also be referred to the descriptions in the above exemplary embodiments.

[0084] The gap-blocking structure in this embodiment adopts the design described above. By setting an inner peripheral frame 1 connecting the steering column cover 4 and an outer peripheral frame 2 connecting the instrument panel frame, and connecting a curtain 3 between the inner peripheral frame 1 and the outer peripheral frame 2, the gap between the instrument panel and the steering column cover 4 can be sealed, which helps to improve the shielding effect on the internal structure of the instrument panel. The curtain 3 can prevent external debris from entering the instrument panel through the gap. At the same time, the curtain 3 seals the gap between the steering column cover 4 and the instrument panel, which can play a sound insulation role, which helps to improve the vehicle's NVH performance and improve the sealing and comfort experience in the cabin.

[0085] An embodiment of the second aspect of this application provides a vehicle having a gap-blocking structure as described in the first aspect of this application.

[0086] In this embodiment, the vehicle is equipped with the aforementioned gap-blocking structure. The curtain 3 can block the gap between the steering column cover 4 and the dashboard, which can better conceal the structure inside the dashboard, enhance the sense of refinement of the interior, and improve the isolation performance between the inside of the dashboard and the cockpit. This is beneficial to improving the vehicle's cockpit sealing, NVH performance, and dustproof capability. Furthermore, the use of a detachable connection between the inner circumferential frame 1 and the steering column cover 4, and a detachable connection between the outer circumferential frame 2 and the dashboard frame, can also reduce the time cost of assembly and maintenance, and improve the maintainability of the vehicle.
