Description

Technical Field

[0001] The present invention particularly relates to a blocking cover for partially shielding a through hole, a blocking cover mounting structure, and a vehicle. Background Art

[0002] like Figure 1 As shown, a limiter 1 (its complete structure is not shown in the figure) which is mainly used to limit the opening of the door 2 is usually provided at the front of the door 2. At this time, a waist-shaped through hole 21 for the limiter 1 to pass through will be correspondingly opened on the door 2; generally speaking, on the front surface of the door 2, part of the structure of the limiter 1 will occupy a part of the space located on the middle side of the through hole 21 (as shown in area A in the figure), and at least two nuts 3 are required to install the limiter 1 on the door 2. The nuts 3 are installed on the door 2 and will be exposed through the through hole 21, which can be observed when the passengers get on the vehicle, resulting in a decrease in the aesthetics of the vehicle and affecting the passengers' riding experience.

[0003] In order to solve this problem, technicians generally set the following on the front surface of the door 2: Figure 2 and Figure 3 The waist-shaped plugging cover 4 shown is made of rubber and is used to cover the portion of the through hole 21 that can expose the nut 3 to achieve the purpose of concealing the ugliness.

[0004] Specifically, the plug cover 4 is as follows Figure 4 As shown, a circle of engaging grooves 43 formed by an inner lip 41 and an outer lip 42 is provided, and the middle portion thereof is partially hollowed out. The blocking cover 4 can form an engaging relationship with the through hole 21 by means of the engaging groove 43, and then be fixed to the vehicle door 2, and the stopper 1 can be passed through the through hole 21 by means of the partially hollowed middle portion thereof; Figure 5 As shown, after the blocking cover 4 is assembled with the vehicle door 2, the outer lip 42 of the blocking cover 4 covers the front surface of the vehicle door 2 (that is, the outer surface of the vehicle door 2), and the blocking cover 4 uses its upper and lower ends to conceal the nut 3, and uses its partially hollowed-out middle part to allow the limiter 1 to pass through; further, an interrupted portion is provided on the outer contour of the blocking cover 4, which forms an air avoidance structure B for freeing up a certain amount of space on the vehicle door 2 to avoid the limiter 1.

[0005] The disadvantage of the above-mentioned blocking cover 4 design is that when the limiter 1 needs to be changed from a non-electric structure to an electric structure, the electric structure requires a through hole 21 with a larger local size than the non-electric structure. The blocking cover 4 of the above-mentioned structure will not be able to adapt well to the through hole 21 with a larger size, or it will need to undergo tedious redesign before it can barely adapt to the through hole 21.

[0006] A more detailed description of this is that, compared with the non-electric structure, the electric structure usually needs to increase the size of the middle part of the through hole 21 by 15-20 mm, such as Figure 6As shown, this is equivalent to the through hole 21 changing from a waist-shaped shape with a maximum width a1 to a shape with a maximum width a2 and approximately elliptical; after the size of the through hole 21 increases, there may not be enough remaining parts on the front surface of the vehicle door 2 for cooperating with the aforementioned snap-in groove 43, nor may there be enough remaining space for arranging the aforementioned outer lip edge 42, which will make the aforementioned type of blocking cover 4 unable to adapt well to the through hole 21 with a width of a2; or, even if the remaining parts and space on the front surface are sufficient, the designer must redesign the specific shape of the snap-in lip, and may need to redesign the specific shape of the air avoidance structure B (if the electric limiter 1 still has a local structure), which is undoubtedly more cumbersome.

[0007] Therefore, for a vehicle door 2 that is changed from using a non-electric limiter to using an electric limiter, the aforementioned type of blocking cover 4 either cannot be well adapted or requires tedious redesign before adaptation, which indirectly increases the design cost of the entire vehicle. Summary of the Invention

[0008] In view of this, the purpose of the present invention is to provide a blocking cover, a blocking cover mounting structure, and a vehicle for partially shielding a through hole. The blocking cover can partially shield the through hole to achieve the purpose of concealing the ugliness, and does not have a full circle of snap-fitting groove structure and does not need to cooperate with the middle part of the through hole.

[0009] The blocking cover provided by the present invention includes a first end, a second end and a connecting rib. There is a gap between the first end and the second end for exposing a portion of the through hole. The connecting rib is located on the same side of the first end and the second end, and is connected to both the first end and the second end. The first end and the second end are used to expose the first side of the through hole and partially shield the through hole. The connecting rib is used to be located on the second side of the through hole, and the first side and the second side are opposite to each other.

[0010] Optionally, the connecting rib includes a first rib body and a second rib body, the two ends of the first rib body are respectively connected to the first end head and the second end head, and the two ends of the second rib body are respectively connected to the first end head and the second end head; the first rib body is provided with a functional part for engaging with the peripheral side of the through hole, and the end of the first rib body is used to be located near the edge of the through hole after the blocking cover is assembled with the through hole, thereby limiting the movement of the blocking cover after being assembled with the through hole.

[0011] Optionally, a limiting portion and a fixing portion are further included, and the first end head and the second end head are both fixed with a fixing portion and a limiting portion, the fixing portion is used to fix the blocking cover, and includes a clamping head that can be clamped with the edge of the through hole, and the limiting portion, the fixing portion and the connecting rib are all located on the same side of the first end head and the second end head; the limiting portion is used to abut against the edge of the through hole to limit the movement of the blocking cover after being assembled with the through hole.

[0012] The present invention also provides a blocking cover installation structure, comprising a blocking cover for partially shielding a through hole as described in any of the above items, and also comprising a component on which the through hole is provided, the blocking cover is fixed on the component, the through hole is provided with a to-be-shielded area and an expected through-hole area, the blocking cover shields the to-be-shielded area, and the gap between the first end head and the second end head is used to expose the expected through-hole area.

[0013] Optionally, the connecting rib is configured so that its orthographic projection on the component is located outside the expected penetration area.

[0014] Optionally, at the junction of the expected penetration area and the blocking cover, an ugliness-covering wall is provided on the first end head and the second end head, and the ugliness-covering walls located on the first end head and the second end head extend from the first end head and the second end head to the second side of the through hole respectively; the connection between the connecting rib and the first end head, the connection between the connecting rib and the second end head, and the fixing portion are all located on the side of the ugliness-covering wall away from the expected penetration area, and the ugliness-covering wall is at least used to cover a part of the connecting rib and the fixing portion.

[0015] The present invention also provides a blocking cover installation structure, including the blocking cover as described above for partially shielding the through hole, the through hole is arranged on the door of the vehicle, the blocking cover is fixed on the door, the through hole is used for the door limiter to pass through it, and the blocking cover is used to shield the nut required for installing the limiter.

[0016] Optionally, a shielding area is provided on the first end head and the second end head for being located on the side of the nut; on the first end head, the connection between the first rib and the first end head, the connection between the second rib and the first end head, the fixing portion and the limiting portion are located outside the shielding area; on the second end head, the connection between the first rib and the second end head, the connection between the second rib and the second end head, the fixing portion and the limiting portion are located outside the shielding area.

[0017] Optionally, a slope is provided on the vehicle door at a peripheral side of the through hole, and the functional portion protrudes toward the vehicle door relative to the first rib at the peripheral side thereof and is configured to engage with the slope.

[0018] The present invention further provides a vehicle, comprising a blocking cover for partially shielding a through hole as described in any one of the above items.

[0019] From the above, it can be seen that by providing a cover that does not contact the middle position of the through hole and can partially cover the through hole, for two through holes that only change the middle size, the cover provided by the present invention can be adapted to both through holes; at the same time, when the vehicle door changes from using a non-electric limiter to using an electric limiter and the middle size of the through hole changes, the designer does not need to redesign the local shape of the cover according to the change in the shape of the through hole, which undoubtedly indirectly reduces the design cost of the entire vehicle.

[0040] The terms "comprises," "comprising," or any other variations thereof herein are intended to cover a non-exclusive inclusion, ie, including elements other than the listed elements and other elements not expressly listed.

[0041] Example 1

[0042] like Figure 7 As shown, this embodiment provides a vehicle, including a door 2 and an electric limiter (not shown), wherein the door 2 is the front door of the vehicle, and a through hole 21 of approximately elliptical shape is provided on the front surface of the door 2. The electric limiter is inserted into the through hole 21 and, as described in the related art, is fixed to the door 2 by means of at least two nuts 3. The two nuts 3 can be exposed to the passenger's visual range through the upper and lower parts of the through hole 21, respectively. On the door 2, the edge of the hole in the middle of the through hole 21 is close to the junction of the front surface of the door 2 and the other side surfaces of the door 2. Therefore, the front surface of the door 2 cannot provide sufficient space for the outer lip 42 of the related art to cover it, and the door 2 cannot adapt to the plug cover 4 with a snap-on groove 43 structure of the related art.

[0043] In view of this, the vehicle of this embodiment further includes a blocking cover 4 which is different from the related art, such as Figure 8 and Figure 9 As shown, the blocking cover 4 includes a first end 44, a second end 45 and a connecting rib 46, wherein there is a gap between the first end 44 and the second end 45 for exposing a portion of the through hole 21, and both ends of the connecting rib 46 are respectively connected to the first end 44 and the second end 45, and all the connecting ribs 4 are located on the same side of the first end 44 and the second end 45.

[0044] Based on the above, the semicircular upper part of the through hole 21 that can expose one nut 3 and the semicircular lower part that can expose another nut 3 are set as the areas to be covered by the through hole 21; the front side is the first side and the rear side is the second side. After the blocking cover 4 and the vehicle door 2 are assembled, the blocking cover 4 is fixed on the vehicle door 2, and the first end 44 is exposed to the first side of the through hole 21 and covers the semicircular upper part of the through hole 21, and the second end 45 is exposed to the first side of the through hole 21 and covers the semicircular lower part of the through hole 21. The connecting ribs 46 are all located on the second side of the through hole 21; at this time, the blocking cover 4 covers the areas to be covered of the through hole 21, leaving only a partially exposed area of ​​the through hole 21 for the intended penetration area for the electric limiter. The aforementioned nut 3 is covered, and the nut 3 will not be exposed within the visible range of the occupant.

[0045] As can be seen from the above, in the blocking cover 4 provided in this embodiment, there is no full circle of snap-in grooves 43 on the blocking cover 4, nor is there a structure for contacting the middle of the through hole 21. Designers do not need to consider any adaptation design between the blocking cover 4 and the middle of the through hole 21, nor do they need to consider the design of the air-avoidance structure B.

[0046] Specifically, the plugging cover 4 in this embodiment is a plastic product formed as one piece by injection molding. The outer contours of the first end 44 and the second end 45 are both composed of special-shaped arcs and line segments that close the arcs. The connecting rib 46 is the main skeleton of the plugging cover 4 used to connect the first end 44 and the second end 45.

[0047] like Figure 10 and Figure 11 As shown, the connecting rib 46 specifically includes a first rib 461 and a second rib 462. The first rib 461 and the second rib 462 are arranged on the left and right sides of the cover 4. The two ends of the first rib 461 are respectively connected to the first end 44 and the second end 45, while the two ends of the second rib 462 are respectively connected to the first end 44 and the second end 45. In this embodiment, the first rib 461 and the second rib 462 are approximately in the shape of arc-shaped handles. Preferably, the first rib 461 and the second rib 462 are configured such that, after the cover 4 is installed on the vehicle door 2, if the orthographic projections of the first rib 461 and the second rib 462 are formed on the front surface of the vehicle door 2, the orthographic projections of the first rib 461 and the second rib 462 are both located outside the intended penetration area of ​​the through hole 21. The main reason for this configuration is to prevent the first rib 461 and the second rib 462 from being easily exposed to the field of view of the occupants and affecting the aesthetics of the vehicle.

[0048] Furthermore, the blocking cover 4 in this embodiment further includes a fixing portion 47 and a limiting portion 48, wherein the fixing portion 47, the limiting portion 48 and the connecting rib 46 are located on the same side of the first end 44 and the second end 45, the fixing portion 47 includes a clamping head that can be engaged with the through hole 21, the first end 44 and the second end 45 are each provided with a fixing portion 47, and the two fixing portions 47 are respectively provided on the upper and lower sides of the second rib 462, and the first end 44 and the second end 45 are each provided with a limiting portion 48, and the two limiting portions 48 are respectively provided at the end of the blocking cover 4. At the highest and lowest points, all the fixing portions 47 and the limiting portions 48 are blocked by the first end 44 or the second end 45, making them difficult to be observed by the occupants; based on this, when the blocking cover 4 needs to be assembled on the vehicle door 2, the fixing portion 47 is engaged with the edge of the through hole 21, so that the blocking cover 4 can be fixed on the vehicle door 2 and is difficult to fall out of the through hole 21; after the blocking cover 4 is engaged with the through hole 21, if the blocking cover 4 has a tendency to move up and down relative to the through hole 21, the limiting portion 48 can be abutted against the edge of the through hole 21, thereby limiting the blocking cover 4 from moving significantly in the through hole 21.

[0049] Furthermore, after the blocking cover 4 is matched with the through hole 21, the connection between the first rib 461 and the first end 44 and the connection between the first rib 461 and the second end 45 in this embodiment are both close to the edge of the through hole 21 (equivalent to blocking one side of the edge of the hole); preferably, the middle part of the first rib 461 protrudes toward the front surface of the vehicle door 2, thereby forming a functional part 4611, and corresponding to the functional part 4611, the front surface of the vehicle door 2 is provided with the following Figure 12 The slope 22 shown is folded backward (please refer to outline I for its direction) and can be engaged with the functional portion 4611. In this way, the arrangement of the first rib 461 close to the edge of the through hole 21, the arrangement of the functional portion 4611, and the arrangement of the fixing portion 47 can work together to prevent the blocking cover 4 from easily moving left and right relative to the through hole 21 after it is assembled on the vehicle door 2. Optionally, the arrangement of the end of the first rib 461 close to the edge of the through hole 21 can also be replaced by the end of the first rib 461 being located very close to the edge of the through hole 21, which can also prevent the blocking cover 4 from easily moving left and right.

[0050] Preferably, since the first rib 461 needs to form a snap-fitting relationship with the vehicle door 2 , the second rib 462 in this embodiment does not directly contact the vehicle door 2 relative to the first rib 461 , so that the blocking cover 4 can be quickly and conveniently assembled on the vehicle door 2 .

[0051] More preferably, in order to ensure the strength of the functional portion 4611, this embodiment further provides a reinforcing rib 4612 at the recess of the functional portion 4611 to fill the recess as much as possible.

[0052] Furthermore, at the upper and lower intersections of the intended penetration area of ​​the through-hole 21 and the blocking cover 4, a concealing wall 49 is provided on the edges of the first end 44 and the second end 45, respectively. The concealing wall 49 extends from the first end 44 or the second end 45 toward the second side of the through-hole 21. In this embodiment, the connection between the connecting rib 46 and the first end 44 or the second end 45 is located on the side of the concealing wall 49 away from the intended penetration area. The fixing portion 47 and the limiting portion 48 are also located on the side of the concealing wall 49 away from the intended penetration area. The concealing wall 49 serves to at least partially conceal the connecting rib 46 and the fixing portion 47, thereby further reducing the likelihood of the aforementioned structures of the blocking cover 4, which faces away from the occupant, being observed by the occupant through the through-hole 21.

[0053] Furthermore, although the fixing portion 47, the limiting portion 48, the connecting rib 46 and the concealing wall 49 are provided on the first end 44 and the second end 45, in order to further ensure that these parts do not interfere with the nut 3, in this embodiment, a flat and smooth shielding area C is further provided on the first end 44 and the second end 45. The shielding area C is an area surrounded by the first rib 461, the second rib 462, the fixing portion 47 and the limiting portion 48, and is used to be located directly in front of the nut 3 to shield the nut 3; specifically, on the first end 44, the connection between the first rib 461 and the first end 44, the connection between the second rib 462 and the first end 44, the fixing portion 47 and the limiting portion 48 are all located outside the shielding area C; on the second end 45, the connection between the first rib 461 and the second end 45, the connection between the second rib 462 and the second end 45, the fixing portion 47 and the limiting portion 48 are all located outside the shielding area C.

[0054] From the above, it can be seen that by providing a cover 4 that does not contact the middle position of the through hole 21 and can partially cover the through hole 21, for two types of through holes 21 that only change the middle size, the cover 4 provided by the present invention can be adapted to both types of through holes 21; at the same time, when the vehicle door 2 changes from using a non-electric limiter to using an electric limiter, and the middle size of the through hole 21 changes, the designer does not need to redesign the local shape of the cover 4 according to the change in the shape of the through hole 21, which undoubtedly indirectly reduces the design cost of the entire vehicle.

[0055] Furthermore, the blocking cover 4 provided by the present invention also has the following beneficial effects:

[0056] 1. Since the blocking cover 4 provided by the present invention is a plastic product, compared with the rubber blocking cover 4 in the related art (which is clamped on the vehicle door 2 by the clamping groove 43), the blocking cover 4 provided by the present invention has a stronger connection force with the vehicle door 2 and is less likely to fall off.

[0057] 2. Since the blocking cover 4 provided by the present invention does not have a matching relationship with the middle position of the through hole 21, the blocking cover 4 provided in this embodiment can indirectly increase the space exposed to the outside of the front surface of the vehicle door 2, and reduce the presence of the blocking cover 4, a part that has an obvious material difference from the vehicle door 2.

[0058] Furthermore, it is easy to know from the above that the blocking cover 4 provided by the present invention can be used not only to cover the through hole 21 on the vehicle door 2, but also for any component, if it meets the following conditions: ① the through hole 21 thereon can expose a certain part, and the part needs to be covered; ② the through hole 21 thereon may undergo local size changes according to design requirements; ③ the change in the local size does not involve the area on the through hole 21 that needs to be covered; then the component may be able to use the blocking cover 4 provided in this embodiment to cover it.

[0059] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
