Description

Technical Field

[0001] The present application relates to the technical field of vehicle engineering, and particularly relates to an outer decorative panel for a pillar, an installation and positioning method, and a vehicle. Background Art

[0002] Currently, a sedan body usually has three pillars, namely the A-pillar, B-pillar, and C-pillar from front to back. The outer decorative panel of the vehicle pillar is the decorative panel on the outer side of the vehicle body pillar, located in the upper area of the outer door frame of the vehicle, and is one of the important structural components of the vehicle. The outer decorative panel of the vehicle pillar not only plays a role in decorating the vehicle body, but also is used to provide a smooth air flow for the vehicle to reduce wind resistance and improve the cruising range of the whole vehicle; in addition, it can also protect the metal parts of the vehicle body from being eroded by stones and rainwater, and extend the service life of the metal parts of the vehicle body.

[0003] In the prior art, the main outer decorative panel of the vehicle door frame pillar has the following technical features. Its top is installed through a fitting hole on the screw mounting post of the mounting part on the outer side of the window frame cross-bar installed on the window frame cross-bar trim, so as to realize the gap positioning between the outer decorative panel of the pillar and the window frame cross-bar trim. A lower mounting part with a mounting hole is provided at the bottom of the outer decorative panel of the pillar. The connection between the lower mounting part and the pillar sheet metal of the vehicle door frame is restricted under the coverage of the outer water cut of the vehicle door. During the installation process of the outer decorative panel of the pillar, it needs to be adjusted up and down, the positioning is not clear, and the operation is inconvenient; moreover, the bottom of the outer decorative panel of the pillar and the outer water cut of the vehicle door are forced to be tightly attached by screws. When there are errors in manufacturing or assembly, problems such as misalignment of the two mounting holes, deformation of the bottom of the outer decorative panel of the pillar under pressure, and rainwater leakage are likely to occur.

[0004] The current existing positioning strategy for the outer decorative panel of the vehicle pillar includes the outer decorative panel body of the pillar. The outer decorative panel body of the pillar includes an outer panel of the decorative panel and an inner panel of the decorative panel. A main positioning structure is provided on the outer decorative panel body of the pillar. The main positioning structure includes an X-direction main positioning rib and a Y-direction main positioning rib provided on the side of the inner panel of the decorative panel. Among them, the X-direction main positioning rib is a single-sided positioning, and the Y-direction main positioning rib is a double-sided positioning.

[0005] For the above-mentioned existing positioning strategy of the outer decorative panel of the vehicle pillar, there is only a single-sided main positioning in the X direction, and the Z direction needs to move upward during the assembly process, so the main positioning setting cannot be carried out. For the above reasons, two people need to operate simultaneously during the assembly process. One person manually pushes the outer decorative panel of the pillar for X-direction and Z-direction positioning, and the other person installs the bolts. There are problems such as difficult assembly and difficult control of the gap surface difference; in terms of X-direction dimension control, it is impossible to ensure that the gap dimension between the outer decorative panel of the pillar and the environmental part in the X direction is uniform after assembly.

[0045] In order to make the objectives, technical solutions and advantages of the present application clearer, the present invention 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 only used to explain the present invention and are not used to limit the present invention. In addition, the technical features involved in the various implementation manners of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0046] In the present application, a column exterior trim panel is provided for decorating the column of a vehicle, including an exterior trim panel 1 and an X-direction main positioning hook 3. It should be noted that in this embodiment and subsequent embodiments, the vehicle coordinate system is used for description, where the front-rear direction of the vehicle is the X direction, the positive direction of the X direction is towards the rear of the vehicle, the left-right direction of the vehicle is the Y direction, the positive direction of the Y direction is towards the right of the vehicle, the up-down direction of the vehicle is the Z direction, and the positive direction of the Z direction is upwards.

[0047] At the same time, in this embodiment and subsequent embodiments, the vehicles to which they are adapted all have an outer door panel, an inner door panel 4, a door reinforcement panel 5 and a glass run channel 6, which are all structures that a general vehicle should have. At the same time, the corresponding vehicle should reserve an installation position for installing the column exterior trim panel.

[0048] Among them, as Figure 1-8 shown, a positioning hook 2 is provided at the edge of the exterior trim panel 1. An X-direction front positioning rib 21, a Y-direction front positioning rib 22 and a Y-direction rear positioning rib 23 are provided inside the positioning hook 2. The positioning hook 2 is not a simple hook, but a long strip-shaped hook structure extending in the Z direction. Among them, the number of X-direction positioning ribs is multiple, and they are arranged in the positioning hook 2 along the Z direction. Specifically, there are four X-direction front positioning ribs 21 in this embodiment. The Y-direction front positioning rib 22 can be seen in Figure 5 , the Y-direction front positioning rib 22 is evenly distributed in the positioning hook 2. Generally speaking, when the Y-direction front positioning rib 22 is close to the X-direction front positioning rib 21, the Y-direction front positioning rib 22 and the X-direction front positioning rib 21 will be connected together to achieve the effect of mutual support, so as to increase the strength of the entire positioning rib and extend the service life. The Y-direction rear positioning rib 23 can be seen in Figure 6, similar to the Y forward positioning ribs 22, they are evenly arranged inside the positioning hook 2. When the Y backward positioning rib 23 and the X forward positioning rib 21 approach each other, they will be joined together. The Y forward positioning rib 22 and the Y backward positioning rib 23 clamp the door reinforcement plate 5 and the inner door panel 4 on both sides, achieving Y-direction positioning.

[0049] In a general embodiment, the positioning hook 2 is arranged in the positive X direction to prevent the exterior trim panel 1 from moving in the negative X direction. In this embodiment, the X main positioning hook 3 is located near the negative X direction of the exterior trim panel 1. There is a hole on the door reinforcement plate 5, and the X main positioning buckle is inserted into the hole on the door reinforcement plate 5 to prevent the exterior trim panel 1 from moving in the positive X direction. Through the cooperation of the X forward positioning rib 21 and the X main positioning hook 3, bilateral positioning of the exterior trim panel 1 is carried out in two directions in the X direction to prevent the exterior trim panel 1 from moving. In this way, when workers fix the exterior trim panel 1 on the pillar, they only need to consider the Z-direction positioning and do not need to consider the X-direction positioning, greatly reducing the work burden. One worker can also complete the installation work of the exterior trim panel 1, reducing the production cost.

[0050] In this embodiment, since the X main positioning rib and the X main positioning hook perform bilateral positioning of the pillar exterior trim panel body in the X direction, it can effectively solve the problem of manually controlling the X-direction position of the pillar exterior trim panel during assembly, and at the same time, it can also solve the problem of difficult control of the X-direction gap of the pillar exterior trim panel; the Y-direction main positioning structure includes Y-direction bilateral main positioning ribs arranged on the side of the inner plate of the exterior trim panel 1, and the Y-direction surface difference between the pillar exterior trim panel body and the surrounding parts is controlled through Y-direction bilateral positioning.

[0051] During some actual use processes, the exterior trim panel 1 is directly pushed upwards until the preset position. During the butting process, it is easy to damage the sheet metal parts, and at the same time, it is also easy to cause scratches on the exterior trim panel 1 itself, affecting its use.

[0052] Therefore, in some preferred embodiments, the above-mentioned exterior trim panel 1 is further provided with a Z-direction positioning surface 13. The Z-direction positioning surface 13 is located at one end of the exterior trim panel 1 in the positive Z direction, that is, the top end of the exterior trim panel 1. The Z-direction positioning surface 13 is usually made of some materials with relatively high surface hardness and relatively soft overall. During installation, it only needs to be pushed upwards until the limit position to ensure that the position of the entire exterior trim panel 1 in the Z direction reaches the specified position.

[0053] During some actual use processes, as Figure 1 shown, especially in terms of Y-direction dimension control, although bilateral main positioning is carried out in the Y direction, the main positioning ribs are only concentrated on one side of the pillar exterior trim panel, and the Y-direction dimension cannot be controlled by the Y-direction main positioning ribs at a distance far from the Y-direction main positioning ribs, resulting in the problem of Y-direction warping.

[0054] In order to solve the problem of Y-direction warping, in some preferred embodiments, a Y-direction auxiliary positioning hook 14 is also provided on the above-mentioned exterior panel 1. The Y-direction auxiliary positioning hook 14 is located on the side of the exterior panel 1 away from the positioning hook 2. Generally, the Y-direction auxiliary positioning hook 14 will extend into the interlayer of some specific structures, and use the interlayer to clamp it therein to prevent the exterior panel 1 from turning outward on the side away from the positioning hook 2.

[0055] In some of the more preferred embodiments, Figure 7 and Figure 8 As shown, the number of the Y-direction auxiliary positioning hooks 14 is two, one of which is as shown in FIG. Figure 7 As shown, insert it into the gap between the corners of the glass run channel 6. Figure 8 As shown, it is inserted into the hole of the door reinforcement panel 5.

[0056] In some practical processes, the exterior panel 1 is injection molded at one time, but the inner and outer parts of the exterior panel 1 have different functions. The outer part is mainly for aesthetics and to prevent damage from debris, while the inner part is mainly for installation, and needs to be relatively hard and easy to install. Therefore, in some preferred embodiments, the exterior panel 1 is divided into two parts, one of which is the exterior outer panel 11 and the other is the exterior inner panel 12. The exterior outer panel 11 is attached to the exterior inner panel 12, and at the same time, Figure 3-8 As shown, all the connection structures, such as the aforementioned X-direction forward positioning rib 21, Y-direction forward positioning rib 22, Y-direction rearward positioning rib 23, X-direction main positioning hook 3 and Y-direction auxiliary positioning hook 14, are arranged on the exterior inner panel 12, and the exterior inner panel 12 is used for more reliable connection. At the same time, the downwardly extending part of the exterior inner panel 12 is mainly used during installation, and can be inserted between the door outer panel and the door inner panel 4 to avoid slipping.

[0057] In some cases, there are many ways to connect the exterior panel 1 and the column, such as gluing, etc., but this method is very disadvantageous for the disassembly of the exterior panel 1.

[0058] Therefore, in some preferred embodiments, a plurality of auxiliary positioning holes 121 are provided on the exterior inner panel 12. Specifically, in this embodiment, there are three auxiliary positioning holes 121, which are evenly distributed along the length of the exterior inner panel 12, and a thickened plate for protecting the auxiliary positioning holes 121 is also provided at the positions of the auxiliary positioning holes 121 on the exterior inner panel 12.

[0059] In some embodiments, the X-axis main positioning hook 3 extends directly from the exterior inner panel 12 and is plugged into the door reinforcement plate 5. This method requires a certain thickness at the plug-in location to accommodate the X-axis main positioning hook 3, which limits the installation position and is not conducive to vehicle design.

[0060] In a further embodiment, a plugging notch 122 is further provided on the exterior trim inner panel 12, and the X-direction main positioning hook 3 is disposed in the plugging notch 122. Specifically, as Figure 1 shown, the position of the plugging notch 122 generally corresponds to the middle of the exterior trim outer panel 11, and opens leftward in the direction shown in the figure. The X-direction main positioning hook 3 is located in the plugging socket and extends in the Y direction. In this way, the X-direction main positioning hook 3 only needs to be inserted into the door reinforcement plate 5, and the X-direction main positioning hook 3 and the exterior trim inner panel 12 clamp the door reinforcement plate 5, so that the position of the X-direction main positioning hook 3 can be stably fixed. At the same time, the side wall of the X-direction main positioning hook 3 restricts the movement of the entire exterior trim panel 1 in the X direction.

[0061] The present application also provides an installation positioning method for installing the aforementioned column exterior trim panel, including the following steps:

[0062] S1. Plug the exterior trim panel 1 between the vehicle's outer door panel and the inner door panel 4. Specifically, near the vehicle's column, a jack is formed between the outer door panel and the inner door panel 4 for plugging the exterior trim panel 1.

[0063] S2. Rotate the exterior trim panel 1 until the edges of the outer door panel and the inner door panel 4 are in contact with the X-direction front positioning rib 21, and the door reinforcement plate 5 is in contact with the Y-direction front positioning rib 22 or the Y-direction rear positioning rib 23. Specifically, during the general installation process, in order to facilitate gripping, the part of the exterior trim panel 1 near the positioning hook 2 is grasped. After the exterior trim panel 1 is inserted into the jack between the outer door panel and the inner door panel 4, the positioning hook 2 needs to be rotated to the corresponding position. Sometimes, the fit between the jack and the exterior trim panel 1 is relatively loose. When the positioning hook 2 is close to the door reinforcement plate 5 and the inner door panel 4, the exterior trim panel 1 can be pushed to make the positioning hook 2 cross the door reinforcement plate 5 and the inner door panel 4 and hook the edges of the door reinforcement plate 5 and the inner door panel 4. In some cases, the connection between the exterior trim panel 1 and the corresponding jack is relatively tight and the moving space is small, and the exterior trim panel 1 cannot be pushed. At this time, the exterior trim panel 1 needs to be pressed to make the positioning hook 2 slightly deformed to cross the door reinforcement plate 5 and the inner door panel 4 and hook the edges of the door reinforcement plate 5 and the inner door panel 4. In some embodiments, the distance between the Y-direction front positioning rib 22 and the Y-direction rear positioning rib 23 in the positioning hook 2 is greater than the thickness of the door reinforcement plate 5 and the inner door panel 4, and there is a small amount of moving space in the Y direction. This is reserved for convenient installation and does not affect the use of the exterior trim panel 1.

[0064] S3. Push the exterior trim panel 1 until it reaches the preset height and connect the X-direction main positioning hook 3 to the door reinforcement plate 5. Specifically, generally, the X-direction main positioning hook 3 is set near the edge of the door reinforcement plate 5 or the hole on the door reinforcement plate 5, and then the X-direction main positioning hook 3 is connected to the door reinforcement plate 5.

[0065] S4. Fasten between the exterior trim panel 1 and the vehicle's pillar. Specifically, generally, a connector is used to fix the exterior trim panel 1 to the vehicle, such as a screw, etc. In some embodiments, structural adhesive bonding is also used.

[0066] In some further embodiments, the exterior trim panel 1 further includes a Z-direction positioning surface 13, which is arranged in the positive Z-direction of the exterior trim panel 1

[0067] The step S3 further includes the following steps:

[0068] S31. Push the exterior trim panel 1 so that the Z-direction positioning surface 13 abuts against the lower surface of the corner joint of the vehicle's glass run channel 6. Specifically, the Z-direction positioning surface 13 is a surface whose shape is adapted to the vehicle model to be installed. The shape of the Z-direction positioning surface 13 is determined according to the shape of the corresponding position of the vehicle model. The Z-direction positioning surface 13 is to help abut against the vehicle frame when pushing up the entire exterior trim panel 1, thereby helping to limit the position of the exterior trim panel 1 in the Z-direction.

[0069] In this application, an embodiment of a vehicle is also provided. In this embodiment, the pillar exterior trim panel is the pillar exterior trim panel as described above. Specifically, the vehicle has an outer door panel, an inner door panel 4, a door reinforcement plate 5, and a glass run channel 6 near the pillar. Among them, the outer door panel and the inner door panel 4 form a hole for inserting the pillar exterior trim panel near the pillar. The edges of the outer door panel, the inner door panel 4, and the door reinforcement plate 5 are used for hanging the pillar exterior trim panel. In some embodiments, there are holes on the door reinforcement plate 5 for installing the X-direction main positioning hook 3 of the pillar exterior trim panel. At least one place on the vehicle has the pillar exterior trim panel as the aforementioned pillar exterior trim panel.

[0070] In this application, a specific pillar exterior trim panel is also taken as an example to illustrate its installation method. In this embodiment, the structure of the pillar exterior trim panel is as Figure 1 shown, and its structure installed on the vehicle is as Figure 2 shown. It specifically includes an exterior trim panel 1 and an X-direction main positioning hook 3.

[0071] The exterior panel 1 is divided into an exterior panel 11 and an exterior panel 12. The exterior panel 11 is for decoration and only covers the surface of the exterior panel 12 in this embodiment, and has no effect on installation. A positioning hook 2 is provided at the edge of the exterior panel 12, and a plurality of X-forward positioning ribs 21, Y-forward positioning ribs 22 and Y-rearward positioning ribs 23 are provided in the positioning hook 2. In the present embodiment, there are four X forward positioning ribs 21, two of which form a group, and the two groups are respectively arranged at the edge of the exterior inner panel 12 close to the Z upward end and the edge close to the X downward end, while there are four Y forward positioning ribs 22 and four Y rearward positioning ribs 23, all of which are roughly evenly arranged in the positioning hook 2. The Y forward positioning ribs 22 and the Y rearward positioning ribs 23 usually need to be staggered by a small distance, so that when the positioning hook 2 is tightly connected to the door inner panel 4 and the door reinforcement plate 5, the thickness of the door inner panel 4 and the door reinforcement plate 5 can be made to slightly exceed the Y-direction spacing between the Y forward positioning ribs 22 and the Y rearward positioning ribs 23, and the edges of the door inner panel 4 and the door reinforcement plate 5 can be slightly deformed to complete the assembly and form an interference fit. If the Y forward positioning ribs 22 and the Y rearward positioning ribs 23 are on the same plane, it will be difficult to assemble the door inner panel 4 and the door reinforcement plate 5 whose total thickness is greater than the spacing between the Y forward positioning ribs 22 and the Y rearward positioning ribs 23.

[0072] The exterior inner panel 12 is also provided with a plugging notch 122, in which an X-direction main positioning hook 3 facing the Y direction is provided, and a hole for installing the X-direction main positioning hook 3 is provided on the door reinforcement plate 5. The exterior inner panel 12 is also provided with a secondary positioning mechanism, which mainly includes a Y-direction secondary positioning hook 14, a Z-direction positioning surface 13 and a secondary positioning hole 121.

[0073] Among them, the number of the Y-axis auxiliary positioning hooks 14 is two, such as Figure 2 As shown, Figure 2 The direction shown in FIG. 1 is used to describe that the two Y-direction auxiliary positioning hooks 14 are both arranged near the head of the exterior trim panel 1. One of the Y-direction auxiliary positioning hooks 14 is located on the side, and the other is located on the top. The Y-direction auxiliary positioning hook 14 located on the side can be seen in FIG. Figure 7 ,exist Figure 7 The Y-direction auxiliary positioning hook 14 extends into the corner of the glass guide groove 6. The Y-direction auxiliary positioning hook 14 located on the top surface can be seen. Figure 8, make holes at the corresponding positions, and insert the Y-direction secondary positioning hooks 14 into the corresponding holes. The Z-direction positioning surface 13 is a surface whose shape is adapted to the vehicle model to be installed. The shape of the Z-direction positioning surface 13 is determined according to the shape of the corresponding position of the vehicle model. The Z-direction positioning surface 13 is used to help abut against the vehicle frame when pushing the entire exterior trim panel 1 upwards, thereby helping to limit the position of the exterior trim panel 1 in the Z direction. The secondary positioning holes 121 are arranged on the interior trim panel 12. There are three secondary positioning holes 121, and the thickness of the interior trim panel 12 is increased at each secondary positioning hole 121 to ensure the stability of the connection.

[0074] The installation of this embodiment has the following steps:

[0075] S001. Insert the bottom of the interior trim panel 12 into the hole formed between the outer door panel and the inner door panel 4.

[0076] S002. Rotate the entire exterior trim panel 1 so that the positioning hooks 2 are sleeved on the edges of the door reinforcement plate 5 and the inner door panel 4, and make the Y-direction front positioning rib 22 fit against the door reinforcement plate 5, as Figure 5 shown, the Y-direction rear positioning rib 23 fits against the inner door panel 4, as Figure 6 shown, and the X-direction front positioning rib 21 fits against the end of the door reinforcement plate 5 and / or the inner door panel 4, as Figure 3 shown.

[0077] S003. Push the exterior trim panel 1 upwards so that the Z-direction positioning surface 13 fits against the lower surface of the corner where the glass run channel 6 of the vehicle is connected, as Figure 7 shown, and at the same time, the X-direction main positioning hook 3 in the middle of the interior trim panel 12 cooperates with the door reinforcement plate 5, as Figure 4 shown; at the same time, in the Figure 2 shown direction, the Y-direction secondary positioning hook 14 near the top fits against the corner of the glass run channel 6, and the structure is as Figure 8 shown; the Y-direction secondary positioning hook 14 near the side fits against the door reinforcement plate 5, and the structure is as Figure 7 shown. Complete the bilateral positioning in the X and Y directions.

[0078] S004. Fasten the interior trim panel 12 and the pillar with bolts to complete the assembly of the exterior trim panel 1.
