Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and more specifically, it relates to a combination switch lower cover assembly, a combination switch, and a vehicle. Background Technology

[0002] The combination switch is mounted on the steering column of a car and is used to control the car's lights, signals, and electrical components. During driving, the steering column needs to be operated frequently, and the combination switch cover will move in different directions with the steering column. This results in a large gap between the lower cover of the combination switch, which is wrapped under the steering column, and the knee trim panel, causing abnormal noises upon impact, and affecting the overall appearance quality and NVH performance of the vehicle. Utility Model Content

[0003] The purpose of this utility model is to provide a combination switch lower cover assembly, combination switch and vehicle, which aims to solve the problems of large fitting gaps and abnormal impact noise between the combination switch and surrounding related components, which affect the overall appearance quality and NVH performance of the vehicle.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A combination switch lower cover assembly is provided, comprising: a combination switch lower cover body and a baffle; a plurality of connecting posts are provided on the inner surface of the combination switch lower cover body; the baffle is connected to the combination switch lower cover body through a plurality of first connecting posts dispersed along the lower boundary of the combination switch lower cover body; the baffle is provided with a first connecting hole corresponding to the first connecting post; wherein, the combination switch lower cover body is further provided with a first limiting structure for limiting the baffle, the first limiting structure constituting a first directional limiting of the baffle.

[0005] The beneficial effects of the combination switch lower cover assembly provided by this utility model are as follows: Compared with the prior art, the combination switch lower cover assembly of this utility model uses a cover to block the gap between the combination switch lower cover body and the knee trim panel. In order to avoid the risk of collision noise or detachment due to unreliable connection limit between the cover and the combination switch lower cover body, multiple first connecting posts are distributed along the lower boundary of the combination switch lower cover body. After the first connecting posts pass through the first connecting holes on the cover, the connection between the cover and the combination switch lower cover body is realized.

[0006] Because the lower cover of the combination switch is U-shaped, the first connecting posts, which are dispersed along the lower boundary of the U-shape, are inclined in different directions. After connecting with the baffle, the first connecting posts in different directions constrain the baffle, thereby achieving the limiting and constraint of the baffle in different directions. After the first connecting post passes through the baffle, the exposed end is formed into a mushroom head or round head by fusion welding, which together constitutes the limiting in the first direction, the second direction, and the third direction. Therefore, it can improve the reliability of the connection between the baffle and the lower cover of the combination switch and prevent the baffle from falling off. This application also specially sets a first limiting structure for limiting the baffle in the first direction. By limiting the baffle with the first limiting structure, it can avoid the phenomenon of abnormal noise caused by the impact between the baffle and the lower cover of the combination switch when the steering column moves due to poor connection of the first connecting post. This improves the appearance quality, driving experience, and refinement of the whole vehicle.

[0007] In conjunction with the first aspect, in one possible implementation, the first limiting structure is a first L-shaped limiting portion formed on the inner surface of the lower cover body of the combination switch; the first L-shaped limiting portion extends in a second direction and forms a first limiting groove for inserting the baffle with the lower cover body of the combination switch, thereby forming an anti-noise limiting for the baffle; wherein, the second direction is perpendicular to the first direction.

[0008] In the above technical solution, the edge of the retaining plate is inserted into the first limiting groove, and the retaining plate abuts against the wall of the first limiting groove. This prevents the risk of abnormal noise caused by impact between the retaining plate and the lower cover of the combination switch due to poor connection via the first connecting post. The retaining plate is an elastic element that, through deformation, is inserted into the first limiting groove and can elastically abut against the inner wall of the first limiting groove, thereby preventing abnormal noise from impact.

[0009] Therefore, the connection between the shield and the lower cover of the combination switch is achieved through the first limiting structure and the first connecting post, which ensures that the shield covers the surrounding gaps and avoids the risk of detachment and abnormal noise caused by poor welding of the shield.

[0010] In conjunction with the first aspect, in one possible implementation, the lower cover body of the combination switch is further provided with a second limiting structure that limits the baffle, the second limiting structure constituting a first directional limiting and a third directional limiting of the baffle; the third directional, the first direction and the second direction are perpendicular to each other.

[0011] The second limiting structure can effectively prevent the stop from being stopped from different directions when the first connecting column fails. This not only prevents the stop from falling off, but also prevents the stop from hitting the lower cover of the combination switch and making abnormal noise.

[0012] In conjunction with the first aspect, in one possible implementation, the second limiting structure is a second L-shaped limiting part formed on the inner surface of the lower cover body of the combination switch. The second L-shaped limiting part extends in the third direction and forms a second limiting groove for inserting the baffle with the lower cover body of the combination switch. The baffle is inserted into the second limiting groove and abuts against the bottom of the groove, forming a third-direction anti-detachment limiting for the baffle, and at the same time forming an anti-noise limiting for the baffle in the first direction.

[0013] The second limiting structure not only prevents the cover from impacting the lower cover of the combination switch in the first direction and causing abnormal noise, but also prevents the cover from falling off due to the stop of the second limiting groove, thus enhancing the overall refinement of the vehicle.

[0014] In conjunction with the first aspect, in one possible implementation, a hooking structure is provided between two adjacent first connecting posts on the inner surface of the lower cover body of the combination switch, and the cover is correspondingly provided with hooking holes for the hooking structure.

[0015] In the above technical solution, the hanging structure and the first connecting post are connected in different ways. The hanging structure is designed as a hook and can be hung on the hanging hole. Combined with the first connecting post, the cover and the lower cover of the combination switch form a variety of connection methods and limit in different directions, thereby preventing the cover from loosening and making abnormal noises.

[0016] In conjunction with the first aspect, in one possible implementation, the hooking hole is a trapezoidal hole with a gradually decreasing hole spacing along the hooking direction to lock the hooking structure. By setting the hooking hole in a trapezoidal shape, the hooking structure can pass through the wider end of the hooking hole and move towards the narrower end, gradually locking itself in place. This ensures that the hooking structure will not wobble after being hooked into the hooking hole, improving the reliability of the connection.

[0017] In conjunction with the first aspect, in one possible implementation, the inner surface of the lower cover body of the combination switch is provided with reinforcing ribs that vary with the direction of the lower boundary, and the baffle is formed with a U-shaped bend that wraps around the reinforcing ribs.

[0018] In the aforementioned technical solution, because the lower cover of the combination switch is U-shaped, although it has a certain degree of rigidity, its thinness makes it prone to deformation. This increases the gap between the retaining plate and the lower cover in some areas, leading to unreliable connections and an increased risk of the retaining plate detaching. By adding reinforcing ribs to the area where the retaining plate connects to the lower cover, the strength is increased, deformation is prevented, and the firmness and reliability of the connection between the retaining plate and the reinforcing ribs are ensured. Furthermore, the wrapping connection between the retaining plate and the reinforcing ribs creates a second-direction restraint, further preventing the risk of the retaining plate detaching along this direction.

[0019] In conjunction with the first aspect, in one possible implementation, the assembly further includes a support plate connected to the inner surface of the lower cover body of the combination switch, with a foam block pressed between the support plate and the lower cover body of the combination switch; after the baffle wraps around the reinforcing rib, it extends and presses between the foam block and the lower cover body of the combination switch.

[0020] In the above technical solution, a support plate is set in the body of the lower cover of the combination switch, which can improve the support strength of the lower cover of the combination switch as a support structure, reduce the risk of deformation of the lower cover of the combination switch, and at the same time, it is also conducive to ensuring the reliability of the connection between the cover and the lower cover of the combination switch, and preventing the risk of abnormal noise from the gap between the two.

[0021] Secondly, this utility model embodiment also provides a combination switch, including the aforementioned combination switch lower cover assembly.

[0022] The combination switch provided in this embodiment of the utility model, due to the use of this combination switch lower cover assembly, can not only cover the gap between the combination switch and the lower knee trim panel, but also does not make any abnormal noise, thereby improving the riding experience of the driver and passengers and the overall refinement of the vehicle.

[0023] Thirdly, this utility model embodiment also provides a vehicle including the aforementioned combination switch lower guard assembly.

[0024] The vehicle provided by this utility model, by adopting this combination switch, can block the gap between the combination switch and the knee trim panel when the steering column moves, without making any abnormal noise, which greatly improves the overall appearance quality and driving experience of the vehicle, thereby enhancing the brand value of the vehicle.

[0028] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a number" means two or more, unless otherwise explicitly specified.

[0031] It should be noted that the directions or positional relationships indicated by "front", "rear", "inner", "outer", "up", and "down" in this embodiment are based on the vehicle's own orientation. The front of the vehicle represents "front", the rear of the vehicle represents "rear", the top of the vehicle represents "up", the bottom of the vehicle represents "down", the "inner" side refers to the side facing the driver's cab, and the "outer" side refers to the side facing the driver's cab.

For greater clarity, combined with... Figure 4 , Figure 5 , Figure 6 , Figure 9 The cross-sectional lines illustrate the orientational relationships, among which, Figure 9 The EE line is the second direction, and the direction perpendicular to the first limiting part at this position is the first direction; corresponding to Figure 4 The second limiting part extends in a third direction.

[0034] To address the issue of a large gap between the lower cover of the combination switch and the knee trim panel, resulting in a poor driving and riding experience, soft rubber is currently commonly used for concealment. However, soft rubber (such as TPE) has a low melting point (80-150℃), and its elastomer molecular structure has poor compatibility with hard plastics. Under prolonged and repeated movement, the adhesive joint is prone to detachment. To address these issues, this invention uses a cover to conceal the gap between the lower cover of the combination switch and the knee trim panel. Furthermore, to ensure the reliable connection between the cover and the lower cover, achieving both the purpose of concealing the gap and preventing noise caused by impact between the cover and the lower cover, the following technical solution is adopted.

[0035] Please refer to the following: Figures 1 to 9The present invention will now describe the combination switch lower cover assembly. The combination switch lower cover assembly includes a combination switch lower cover body 1 and a baffle 3; a plurality of connecting posts are provided on the inner surface of the combination switch lower cover body 1; the baffle 3 is connected to the combination switch lower cover body 1 through a plurality of first connecting posts 11 distributed along the lower boundary of the combination switch lower cover body 1; the baffle 3 is provided with a first connecting hole corresponding to the first connecting post 11; wherein, the combination switch lower cover body 1 is also provided with a first limiting structure 14 for limiting the baffle 3, the first limiting structure 14 constituting a first directional limiting of the baffle 3.

[0036] The beneficial effects of the combination switch lower cover assembly provided by this utility model are as follows: Compared with the prior art, the combination switch lower cover assembly of this utility model uses a cover 3 to cover the gap between the combination switch lower cover body 1 and the knee trim panel. In order to avoid the risk of collision noise or detachment caused by unreliable connection between the cover 3 and the combination switch lower cover body 1, a plurality of first connecting posts 11 are distributed along the lower boundary of the combination switch lower cover body 1. The first connecting posts 11 pass through the first connecting holes on the cover 3 one by one to realize the connection between the cover 3 and the combination switch lower cover body 1.

[0037] Since the lower cover body 1 of the combination switch is U-shaped, the first connecting posts 11, which are distributed along the lower boundary of the U-shape, are inclined in different directions. After connecting with the baffle 3, the first connecting posts 11 in different directions restrain the baffle 3, thereby achieving the limiting and constraint of the baffle 3 in different directions. After the first connecting post 11 passes through the baffle 3, the exposed end is formed into a mushroom head or round head after being fused and welded, which together constitutes the limiting in the first direction, the second direction and the third direction. Therefore, the reliability of the connection between the baffle 3 and the lower cover body 1 of the combination switch can be improved, and the baffle 3 can be prevented from falling off. This application also specially sets a first limiting structure 14 that limits the baffle 3 in the first direction. By limiting the baffle 3 with the first limiting structure 14, the phenomenon of abnormal noise caused by the impact between the baffle 3 and the lower cover body 1 of the combination switch when the steering column moves due to poor connection of the first connecting post 11 can be avoided, thereby improving the appearance quality, driving experience and refinement of the whole vehicle.

[0038] Among them, the lower cover body 1 of the combination switch serves as a supporting structure and requires a certain degree of hardness and strength. It can be injection molded using the current process and materials. The baffle 3 is made of plastic or rubber material that is harder than soft rubber but softer than the material of the lower cover body 1 of the combination switch. It can reliably connect with the lower cover body 1 of the combination switch and also has a certain degree of flexibility or elasticity to block the surrounding gaps when moving with the steering column.

[0039] For example, this application provides eight first connecting posts 11, with supporting steps arranged around each first connecting post 11. The retaining plate 3 is supported on the supporting steps, and the position of the supporting steps forms a local reinforcement structure, which can improve the reliability of the positioning support of the retaining plate 3. The structure of the supporting steps can be found in [reference needed]. Figure 4 As shown.

[0040] NVH performance (Noise, Vibration, and Harshness) is the most direct and superficial feeling for occupants in a vehicle. It is an important indicator for measuring the comfort and manufacturing process of a car and directly affects the driving and riding experience.

[0041] In some embodiments, see Figure 8 and Figure 9 The first limiting structure 14 is a first L-shaped limiting part formed on the inner surface of the lower cover body 1 of the combination switch; the first L-shaped limiting part extends in the second direction and forms a first limiting groove for inserting the baffle 3 between it and the lower cover body 1 of the combination switch, forming a noise-proof limiting of the baffle 3; wherein, the second direction is perpendicular to the first direction.

[0042] In the above technical solution, the edge of the retaining plate 3 is inserted into the first limiting groove, and the retaining plate 3 abuts against the groove wall of the first limiting groove. This prevents the risk of abnormal noise caused by impact between the retaining plate 3 and the lower cover body 1 of the combination switch due to poor connection via the first connecting post 11. The retaining plate 3 is an elastic element that, through deformation and insertion into the first limiting groove, can elastically abut against the inner wall of the first limiting groove, thereby preventing abnormal noise from impact.

[0043] Therefore, the connection between the shield 3 and the lower cover body 1 of the combination switch is achieved through the first limiting structure 14 and the first connecting post 11, which can ensure that the shield 3 covers the surrounding gaps and avoid the risk of detachment and abnormal noise caused by poor welding of the shield 3.

[0044] To further explain, since a clearance needs to be reserved between the first connecting holes through which the first connecting post 11 passes, so as to insert the first connecting post 11, which is located on different curved surfaces, into the first connecting hole, due to the clearance fit between the first connecting post 11 and the first connecting hole, even after the end of the first connecting post 11 is fused and welded, there may still be an impact noise between the baffle 3 and the lower cover body 1 of the combination switch when the steering column moves and the whole vehicle vibrates. At the same time, due to the uneven force, there may also be a phenomenon that the welding of one of the first connecting posts 11 is not firm. Therefore, under the premise of using the connecting post as the basic connection, by adding the first limiting structure 14, the risk of impact noise between the baffle 3 and the lower cover body 1 of the combination switch caused by poor welding of the connecting post can be avoided to a certain extent.

[0045] For example, the first connecting post 11 is integrally injection molded with the lower cover body 1 of the combination switch, or the first connecting post 11 is bonded to the lower cover body 1 of the combination switch.

[0046] The shape of the first connecting post 11 can be cylindrical, square, flat, or otherwise unrestricted. A reinforcing rib can also be provided between the first connecting post 11 and the lower cover body 1 of the combination switch to improve the reliability of the first connecting post 11's positioning.

[0047] Furthermore, in order to facilitate the insertion of the baffle 3 into the first limiting groove, a guide slope is provided on the inner side of the opening end of the first L-shaped limiting part to facilitate the smooth insertion of the baffle 3.

[0048] In some embodiments, see Figure 3 and Figure 4 The lower cover body 1 of the combination switch is also provided with a second limiting structure 15 of the limiting block 3. The second limiting structure 15 constitutes the first direction limiting and the third direction limiting of the block 3; the third direction, the first direction and the second direction are perpendicular to each other.

[0049] The purpose of the second limiting structure 15 is primarily to prevent the cover 3 from detaching from the first connecting post 11 when the connection fails. The cooperation between the second limiting structure 15 and the first limiting structure 14 effectively prevents the cover 3 from being limited from different directions even when the first connecting post 11 fails, thus preventing the cover 3 from falling off and also preventing it from impacting the lower cover body 1 of the combination switch and causing abnormal noise. This combined design enhances the overall refinement of the vehicle.

[0050] Alternatively, the second limiting structure 15 can be provided on the lower cover body 1 of the combination switch, that is, the second limiting structure 15 cooperates with the first connecting column 11, which can also improve the overall vehicle's refined feel.

[0051] In some embodiments, see Figure 3 and Figure 4 The second limiting structure 15 is a second L-shaped limiting part formed on the inner surface of the lower cover body 1 of the combination switch. The second L-shaped limiting part extends in the third direction and forms a second limiting groove for inserting the baffle 3 between it and the lower cover body 1 of the combination switch. The baffle 3 is inserted into the second limiting groove and abuts against the bottom of the groove, forming a third-direction anti-dislodgement limiting of the baffle 3, and at the same time forming an anti-noise limiting of the baffle 3 in the first direction.

[0052] During installation, the cover 3 deforms and inserts into the second limiting groove. The second limiting structure 15 not only prevents the cover 3 from impacting the lower cover body 1 of the combination switch in the first direction and causing abnormal noise, but also prevents the cover 3 from falling out due to the stop of the second limiting groove, thus improving the overall refinement of the vehicle.

[0053] The second limiting structure 15 is integrally injection molded with the lower protective cover body 1 of the combination switch.

[0054] In some embodiments, see Figure 3 and Figure 5 On the inner surface of the lower cover body 1 of the combination switch, a hanging structure 13 is set between two adjacent first connecting posts 11, and a corresponding hanging hole for the hanging structure 13 is provided on the cover 3.

[0055] In the above technical solution, the hanging structure 13 and the first connecting post 11 are connected in different ways. The hanging structure 13 is designed as a hook and can be hung on the hanging hole. Combined with the first connecting post 11, the cover 3 and the lower cover body 1 of the combination switch form a variety of connection methods and limit in different directions, thereby preventing the cover 3 from loosening and making abnormal noises.

[0056] Due to the irregular shape of the lower cover body 1 of the combination switch, which forms a U-shaped structure with varying curvature at different locations, and the fact that the first connecting posts 11 are not easily installed on the opposite sides of the U-shape, the distribution of the first connecting posts 11 along the lower boundary of the lower cover body 1 of the combination switch is uneven. This results in some locations lacking the connection of the first connecting post 11, leading to a large gap between the cover 3 and the lower cover body 1 of the combination switch, which can easily cause impacts and abnormal noises. To fill this gap, a hanging structure 13 is added to increase the connection points between the cover 3 and the lower cover body 1 of the combination switch, thereby avoiding the risk of abnormal noises.

[0057] For example, the mounting structure 13 is positioned between the two farthest adjacent first connecting posts 11.

[0058] In some embodiments, see Figure 3 and Figure 5 The mounting holes are trapezoidal holes with a gradually decreasing hole spacing along the mounting direction to lock the mounting structure 13. By setting the mounting holes in a trapezoidal shape, the mounting structure 13 can easily pass through the wider end of the mounting hole and move towards the narrower end, gradually locking itself in place. This ensures that the mounting structure 13 will not wobble after being mounted with the mounting hole, improving the reliability of the connection.

[0059] In some embodiments, see Figure 1 , Figure 3 and Figure 6 The inner surface of the lower cover body 1 of the combination switch is provided with reinforcing ribs 17 that change with the direction of the lower boundary, and the cover 3 is formed with a U-shaped bend 18 that wraps around the reinforcing ribs 17.

[0060] Because the lower cover body 1 of the combination switch is U-shaped, although it has a certain degree of rigidity, its thinness makes it prone to deformation. This increases the gap between the retaining plate 3 and the lower cover body 1, leading to unreliable connections and a greater risk of the retaining plate 3 detaching. Reinforcing ribs 17 are installed on the lower cover body 1 where the retaining plate 3 connects to strengthen it and prevent deformation, ensuring the firmness and reliability of the connection between the retaining plate 3 and the reinforcing ribs 17. Furthermore, the wrapping connection between the retaining plate 3 and the reinforcing ribs 17 creates a second-direction limit, further preventing the risk of the retaining plate 3 detaching along the second direction.

[0061] In some embodiments, see Figure 1 , Figure 3 and Figure 7 The assembly also includes a support plate 2 connected to the inner surface of the lower cover body 1 of the combination switch, and a foam block 4 is pressed between the support plate 2 and the lower cover body 1 of the combination switch; after the baffle 3 wraps around the reinforcing rib 17, it extends and presses between the foam block 4 and the lower cover body 1 of the combination switch.

[0062] Setting a support plate 2 inside the lower cover body 1 of the combination switch can improve the support strength of the lower cover body 1 as a support structure, reduce the risk of deformation of the lower cover body 1, and at the same time, it can also help ensure the reliability of the connection between the baffle 3 and the lower cover body 1 of the combination switch, and prevent the risk of abnormal noise from the gap between the two.

[0063] The support plate 2 is made of a metal material with greater strength than the lower cover body 1 of the combination switch to ensure the reliability of the support; the support plate 2 can be made of stainless steel, aluminum or other materials.

[0064] To prevent impact noise between the support plate 2 and the lower cover body 1 of the combination switch, a foam block 4, or sponge, or elastic pad is provided between the support plate 2 and the lower cover body of the combination switch.

[0065] Among them, multiple snap-fit ​​structures 16 and a second connecting post 12 connecting the support plate 2 are provided on the inner surface of the lower cover body 1 of the combination switch to ensure the firmness of the connection between the support plate 2 and the lower cover body 1 of the combination switch.

[0066] Based on the same inventive concept, this application also provides a combination switch, including the aforementioned combination switch lower cover assembly.

[0067] The combination switch provided in this embodiment of the utility model, due to the use of this combination switch lower cover assembly, can not only cover the gap between the combination switch and the lower knee trim panel, but also does not make any abnormal noise, thereby improving the riding experience of the driver and passengers and the overall refinement of the vehicle.

[0068] Based on the same inventive concept, embodiments of this application also provide a vehicle, including the aforementioned combination switch lower guard assembly.

[0069] The vehicle provided by this utility model, by adopting this combination switch, can block the gap between the combination switch and the knee trim panel when the steering column moves, without making any abnormal noise, which greatly improves the overall appearance quality and driving experience of the vehicle, thereby enhancing the brand value of the vehicle.

[0070] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
