In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0038] In the description of the embodiments of the present application, it should be noted that the directions or positional relationships indicated by the terms “first direction”, “second direction”, and “third direction” are based on the attached Figure 2 , Attachment Figure 6 And attached Figure 7 The orientation or positional relationship shown, these orientation terms are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0039] Furthermore, the terms “first,” “second,” “third,” etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

[0040] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] In a first aspect, an embodiment of the present application provides a vehicle, see Figure 6 and Figure 7 The automobile 100 includes a roof 20, a side panel 30, a connecting member 40, and a roof trim strip 10 according to any embodiment of the present application.

[0042] The type of the automobile 100 is not limited. For example, the automobile 100 in the embodiment of the present application may be a sedan.

[0043] A groove 100a is formed at the welding point of the top cover 20 and the side panel 30. The roof area of ​​the automobile 100 is formed by welding the top cover 20 and the side panel 30. In order to realize the welding process of the top cover 20 and the side panel 30, the top cover 20 and the side panel 30 are overlapped through the groove 100a before the welding operation is carried out. The groove 100a is U-shaped and extends along the front and rear direction of the automobile 100. After the welding operation is completed, the groove 100a used for the welding operation will form an appearance defect. By arranging the top cover decorative strip 10 in the groove 100a, the groove 100a can be covered and decorated.

[0044] The structure of the top cover 20 is not limited. For example, please continue to refer to Figure 6 and Figure 7 The top cover 20 includes a top cover outer panel 21 and a top cover reinforcement 22. The top cover reinforcement 22 can ensure the overall structural strength of the top cover 20. The top cover reinforcement 22 is welded to the top cover outer panel 21 and then welded to the side panel 30. The top cover outer panel 21, the top cover reinforcement 22 and the side panel 30 are jointly arranged to form a groove 100a.

[0045] The connecting member 40 is disposed in the groove 100 a , and a connecting portion 121 a is disposed on the roof decorative strip 10 . The connecting portion 121 a is connected to the connecting member 40 , so that the roof decorative strip 10 can be installed in the groove 100 a .

[0046] A second aspect of the present application provides a roof trim strip for a car 100, see Figure 1 and Figure 2 The top cover decoration strip 10 includes a decoration strip frame 11 and a connecting structure 12 .

[0047] The decorative strip skeleton 11 may be an appearance component of the roof decorative strip 10, and the decorative strip skeleton 11 is exposed to the outside of the automobile 100, and plays the role of decorating the groove 100a. For example, the decorative strip skeleton 11 may be sprayed with paint as required to improve the appearance.

[0048] The material of the decorative strip frame 11 is not limited. For example, it can be aluminum alloy, which has good anti-corrosion performance, thereby increasing the service life of the decorative strip frame 11.

[0049] A covering piece may also be provided on the decorative strip frame 11 . The decorative strip frame 11 plays a role of supporting the covering piece, and the covering piece serves as an appearance component of the automobile 100 .

[0050] The material of the covering piece is not limited, for example, it can be a skin.

[0051] The decorative strip frame 11 is formed with an installation area 11a, and at least a portion of the connection structure 12 is disposed in the installation area 11a. In other words, the connection structure 12 may be entirely or partially located in the installation area 11a, and the decorative strip frame 11 may form a certain covering effect on the connection structure 12, thereby facilitating the connection between the decorative strip frame 11 and the connection structure 12.

[0052] The connecting structure 12 includes a main body 121 , and a connecting portion 121 a is provided on the main body 121 . The connecting portion 121 a is used to connect with the automobile 100 .

[0053] Specifically, a connecting member 40 is disposed in the groove 100 a of the automobile 100 , and the connecting portion 121 a is connected to the connecting member 40 , so that the roof trim strip 10 can be installed in the groove 100 a as a whole.

[0054] The decorative strip skeleton 11 is formed with a first limiting portion 112a, and the connecting structure 12 includes a limiting component 122 arranged on the main body 121, and the limiting component 122 is provided with a second limiting portion 1223b. One of the first limiting portion 112a and the second limiting portion 1223b is a limiting protrusion, and the other is a limiting groove. The limiting protrusion and the limiting groove are snap-fitted together to limit the decorative strip skeleton 11 and the connecting structure 12 in the first direction.

[0055] The specific direction of the first direction is not limited. For example, the first direction in the embodiment of the present application can be understood as the front-rear direction of the automobile 100. In other words, the first direction is consistent with the extension direction of the groove 100a.

[0056] The size of the limiting protrusion along the first direction may be slightly smaller than the size of the limiting groove along the first direction, so that there is a certain difference in length between the limiting groove and the limiting protrusion along the first direction, thereby reducing the risk of interference between the limiting protrusion and the limiting groove.

[0057] It should be noted that the specific value of the difference is not limited. For example, the difference in length between the limiting protrusion and the limiting groove along the first direction is 0.1 mm (millimeter). The 0.1 mm size difference reduces the risk of interference between the limiting protrusion and the limiting groove, facilitating installation between the two. At the same time, the 0.1 mm size difference will not form too much gap between the limiting protrusion and the limiting groove, and will not produce too much relative displacement between the two, that is, it will not have too much impact on the limiting strength of the decorative strip skeleton 11 and the connecting structure 12 in the first direction.

[0058] In the related art, the length of the groove along the front-to-back direction of the automobile is relatively large, which is not conducive to the stable installation of the decorative strip frame on the connecting structure. At the same time, when the automobile is driving, due to acceleration or deceleration, there is a certain difference in self-weight between the decorative strip frame and the connecting structure, which makes the inertia force between the two different. The decorative strip frame and the connecting structure may produce relative displacement along the first direction, resulting in failure of the connection between the two in this direction.

[0059] In the roof decorative strip of the embodiment of the present application, a first limiting portion 112a is formed on the decorative strip skeleton 11, and the connecting structure 12 includes a limiting assembly 122, and a second limiting portion 1223b is provided on the limiting assembly 122. One of the first limiting portion 112a and the second limiting portion 1223b is a limiting protrusion, and the other is a limiting groove. The limiting protrusion and the limiting groove are engaged and matched, and are used to limit the decorative strip skeleton 11 and the connecting structure 12 in the first direction. The first direction can be consistent with the extension direction of the groove 100a. During the transportation or driving of the automobile 100, the inertial force between the decorative strip skeleton 11 and the connecting structure 12 can be buffered by the cooperation of the limiting protrusion and the limiting groove, thereby reducing the risk of relative sliding between the decorative strip skeleton 11 and the connecting structure 12. The overall reliability of the roof decorative strip 10 is higher, and it is not easy to cause the problem of positioning force attenuation after long-term use, thereby improving customer satisfaction.

[0060] It should be noted that the number of the limiting protrusions and the limiting grooves is not limited. Figures 1 to 5 There are two first limiting portions 112a and two second limiting portions 1223b. Through the two sets of limiting protrusions and limiting grooves, the risk of rotation of the decorative strip skeleton 11 and the connecting structure 12 during the assembly process is reduced, which facilitates the assembly of the decorative strip skeleton 11 and the connecting structure 12, thereby improving the production efficiency of the top cover decorative strip 10.

[0061] The structure of the limiting component 122 is not limited. Figure 1 , Figure 2 and Figure 4In one embodiment, the limiting assembly 122 includes a first limiting block 1221, which is disposed in the installation area 11a, and the first limiting block 1221 abuts against the side walls of the installation area 11a on both sides along the second direction, so as to limit the decorative strip skeleton 11 and the connecting structure 12 in the second direction.

[0062] The first direction intersects with the second direction. Exemplarily, the first direction is orthogonal to the second direction, that is, the second direction can be understood as the left-right direction of the automobile 100 .

[0063] It can be understood that after the first limit block 1221 abuts against the side walls of the installation area 11a on both sides along the second direction, the decorative strip skeleton 11 on both sides along the second direction constrain each other, and the decorative strip skeleton 11 and the connecting structure 12 will not produce too much displacement in the second direction, thereby enhancing the installation reliability of the decorative strip skeleton 11 on the connecting structure 12 along the second direction.

[0064] The position of the first limit block 1221 on the body 121 is not limited, as long as both sides of the first limit block 1221 along the second direction can respectively abut against the side walls of the installation area 11a. Figures 1 to 5 The first limiting block 1221 is disposed at at least one end of the body 121 along the first direction. That is, the decorative strip skeleton 11 can be limited in the second direction by one first limiting block 1221.

[0065] Specifically, both ends of the body 121 along the first direction are provided with first limit blocks 1221, that is, the two first limit blocks 1221 are arranged at intervals along the first direction, and the connection structure 12 has multiple limit points for limiting the decorative strip skeleton 11 along the second direction, and the multiple limit points are arranged at intervals in the first direction. It can be understood that multiple limit points can reduce the risk of the decorative strip skeleton 11 rotating on the connection structure 12, thereby facilitating the assembly between the decorative strip skeleton 11 and the connection structure 12, and improving the production efficiency of the top cover decorative strip 10.

[0066] For further information, see Figure 2 , Figure 3 , Figure 6 and Figure 7 The limiting assembly 122 is provided with a first limiting surface 1222a and a second limiting surface 1223a opposite to each other along the third direction. That is, the first limiting surface 1222a and the second limiting surface 1223a are not on the same plane along the third direction, and there is a gap between them along the third direction.

[0067] Part of the decorative strip skeleton 11 is sandwiched between the first limiting surface 1222a and the second limiting surface 1223a. That is, part of the decorative strip skeleton 11 is located in the gap between the first limiting surface 1222a and the second limiting surface 1223a, and at the same time, the part of the decorative strip skeleton 11 located between the first limiting surface 1222a and the second limiting surface 1223a abuts against the first limiting surface 1222a and the second limiting surface 1223a on both sides along the third direction, respectively, for limiting the decorative strip skeleton 11 and the connecting structure 12 in the third direction.

[0068] The first direction, the second direction and the third direction intersect each other and are not coplanar. In the embodiment of the present application, the third direction can be understood as the top and bottom direction of the automobile 100. In this way, the first direction, the second direction and the third direction form a three-dimensional coordinate system, and the decorative strip skeleton 11 and the connecting structure 12 are limited in three directions, and the installation reliability of the decorative strip skeleton 11 on the connecting structure 12 is higher.

[0069] The types of the first limiting surface 1222a and the second limiting surface 1223a are not limited, for example, they can be a plane or a curved surface, and the surfaces of the decorative strip skeleton 11 that abut against the first limiting surface 1222a and the second limiting surface 1223a are respectively adapted to the first limiting surface 1222a and the second limiting surface 1223a.

[0070] The decorative strip skeleton 11 is sandwiched between the first limiting surface 1222a and the second limiting surface 1223a in any manner. Figure 1 , Figure 3 and Figures 5 to 7 The decorative strip skeleton 11 comprises a cover body 111 and a connector 112, and the connector 112 is disposed on both sides of the cover body 111 along the second direction. The decorative strip skeleton 11 is limited in the third direction by the connector 112 and the connecting structure 12.

[0071] The cover body 111 and the connecting body 112 are arranged to form a mounting area 11a. That is, in this embodiment, the wall surfaces of the two connecting bodies 112 that are opposite to each other along the second direction are respectively in contact with the side walls of the first limiting block 1221 at both sides along the second direction.

[0072] Part of the connecting body 112 is sandwiched between the first limiting surface 1222a and the second limiting surface 1223a.

[0073] The first limiting portion 112 a is disposed on the connecting body 112 . That is, in this embodiment, the limiting protrusion or the limiting groove is disposed on the connecting body 112 .

[0074] It can be understood that the decorative strip skeleton 11 is divided into a cover body 111 and a connector 112. The decorative strip skeleton 11 realizes limitation in the first direction, the second direction and the third direction through the connector 112 and the connecting structure 12. There is no need to set a limiting structure on the cover body 111. In this way, the cover body 111 can be set to a flat plate or other shape that matches the roof of the car 100, thereby making the overall decorative effect of the roof decorative strip 10 better.

[0075] The specific shape of the connector 112 is not limited. For example, see Figure 1 , Figure 2 , Figure 6 and Figure 7 The connecting body 112 includes a first connecting section 1121 and a second connecting section 1122. The first connecting section 1121 is connected to the cover body 111. The second connecting section 1122 is arranged on a side of the first connecting section 1121 away from the cover body 111 along the third direction, and extends along the second direction to a side close to the first limiting block 1221. The second connecting section 1122 is clamped between the first limiting surface 1222a and the second limiting surface 1223a.

[0076] It can be understood that the cross-section of the connecting body 112 is similar to an "L" shape, that is, the second connecting section 1122 and the cover body 111 are spaced apart along the third direction, so that the side wall of the connecting body 112 facing the cover body 111 will not be completely connected to the cover body 111, which facilitates the first limiting surface 1222a and the second limiting surface 1223a to abut against the two sides of the connecting body 112 along the third direction.

[0077] At least a portion of the first limiting portion 112a is disposed on the second connecting section 1122. Figure 1 Taking the first limiting portion 112a as an example of the limiting groove, the size of the second connecting section 1122 along the second direction is relatively large, and the size of the limiting groove can be designed to be larger accordingly, so that the clamping fit with the limiting protrusion is better.

[0078] In some embodiments, the limiting groove may be formed separately on the second connecting section 1122, and the second connecting section 1122 may satisfy the setting of the limiting groove.

[0079] In other embodiments, the limiting groove can run through the entire connector 112, that is, a portion is formed on the second connecting segment 1122, and the other portion is formed on the first connecting segment 1121. In this way, the first connecting segment 1121 can also provide a certain clamping force, making the clamping fit between the limiting protrusion and the limiting groove more stable.

[0080] In one embodiment, please refer to Figures 2 to 5 and Figure 7The limiting assembly 122 includes an elastic buckle 1222, which is arranged on both sides of the first limiting block 1221 along the second direction, and a first limiting surface 1222a is formed on a side of the elastic buckle 1222 away from the cover body 111, and the elastic buckle 1222 can be elastically deformed along the second direction.

[0081] When assembling the decorative strip skeleton 11 and the connecting structure 12, the decorative strip skeleton 11 can be pressed along the third direction, and the pressing force acts on the elastic buckle 1222 through the second connecting section 1122, thereby forcing the elastic buckle 1222 to produce a displacement along the second direction. The second connecting section 1122 can move along the third direction on the surface of the elastic buckle 1222. After the second connecting section 1122 passes over the elastic buckle 1222, the elastic buckle 1222 restores its elastic deformation, so that the second connecting section 1122 is located on the side of the first limiting surface 1222a formed by the elastic buckle 1222, and the first limiting surface 1222a can form a limiting effect on the second connecting section 1122.

[0082] It can be understood that, in this embodiment, the elastic buckle 1222 can facilitate the second connecting section 1122 to be assembled to one side of the first limiting surface 1222a.

[0083] In one embodiment, please refer to Figure 3 The side wall of the first limit block 1221 is recessed to form a mounting groove 1221a, and the elastic buckle 1222 is arranged in the mounting groove 1221a. On the one hand, the mounting groove 1221a provides a mounting position for the elastic buckle 1222, which is convenient for the installation of the elastic buckle 1222; on the other hand, by arranging the elastic buckle 1222 in the mounting groove 1221a, the elastic buckle 1222 will not protrude too much from the first limit block 1221 along the second direction, that is, along the second direction, there may be a part of the side wall of the elastic buckle 1222 that does not protrude from the side wall of the first limit block 1221, so that the elastic buckle 1222 will not affect the abutment and limiting between the first limit block 1221 and the second connecting section 1122.

[0084] The specific structure of the mounting groove 1221a is not limited. Figure 3 Both sides of the installation groove 1221a along the third direction are open, that is, the side of the elastic buckle 1222 close to the cover body 111 along the third direction will not be blocked. In this way, during the installation of the decorative strip skeleton 11, the pressing force can be applied to the elastic buckle 1222 through the second connecting section 1122.

[0085] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 6The limiting assembly 122 includes a second limiting block 1223, which is disposed on both sides of the first limiting block 1221 along the second direction, and a second limiting surface 1223a is formed on a side of the second limiting block 1223 facing the cover body 111. That is, the second limiting surface 1223a is located on both sides of the first limiting block 1221 along the second direction.

[0086] It can be understood that the second connecting section 1122 has a certain size along the second direction. After the second connecting section 1122 abuts against the first limiting block 1221, the second connecting section 1122 is located on the outside of the first limiting block 1221 along the second direction. By setting the second limiting surface 1223a on the outside of the first limiting block 1221 along the second direction, the second limiting surface 1223a can facilitate the limitation of the second connecting section 1122 along the third direction.

[0087] In one embodiment, please continue to refer to Figure 3 The second limiting portion 1223b is disposed on the second limiting surface 1223a. That is, the second limiting portion 1223b is disposed on one side of the second limiting block 1223 forming the second limiting surface 1223a.

[0088] According to the above, the first limiting portion 112a is at least partially arranged on the second connecting section 1122, and the snap-fitting between the first limiting portion 112a and the second limiting portion 1223b and the abutting fitting between the second limiting surface 1223a and the second connecting section 1122 can be achieved by the second limiting block 1223. In this way, the structure of the connecting structure 12 is simpler and the process implementation difficulty is lower.

[0089] In one embodiment, please refer to Figures 2 to 6 The connecting portion 121a is a snap-fitting hole. The body 121 includes two connecting plates 1211 spaced apart along the second direction. A snap-fitting hole is formed between the two connecting plates 1211. The snap-fitting hole is used for snap-fitting with the automobile 100.

[0090] It can be understood that, in this embodiment, the side walls of the two connecting plates 1211 that are opposite to each other along the second direction can be recessed in directions away from each other, so that the method of enclosing and forming the snap-fitting holes is more convenient and has lower production difficulty.

[0091] There is no limit to the manner in which the snap-fitting hole is snap-fitted with the automobile 100. For example, a first flange 121b is formed on the snap-fitting hole, and a second flange 40a is provided on the connecting member 40. When the roof trim strip 10 is assembled to the automobile 100, a force is applied to the roof trim strip 10 along the third direction, and the connecting member 40 can enter the snap-fitting hole, and the second flange 40a passes over the first flange 121b, thereby forming a snap-fitting connection.

[0092] It is understandable that in order to facilitate the second flange 40a to pass over the first flange 121b, the clamping hole needs to produce a certain elastic deformation, that is, under the action of the second flange 40a, the aperture of the clamping hole can be appropriately increased. Figure 2 , Figure 3 and Figure 6 The limiting assembly 122 includes two first limiting blocks 1221 and two second limiting blocks 1223. The two connecting plates 1211 and the two second limiting blocks 1223 are connected between the two first limiting blocks 1221 along the first direction. The two second limiting blocks 1223 are located on the outside of the two connecting plates 1211 and are spaced apart from the connecting plates 1211.

[0093] In this embodiment, there is a gap between the connecting plate 1211 and the second limiting block 1223 along the second direction, so that the connecting plate 1211 is convenient to generate elastic deformation along the second direction.

[0094] The specific type of the connecting member 40 is not limited. For example, it can be a screw, and the head of the screw is the second flange 40a.

[0095] In one embodiment, please refer to Figure 1 and Figure 3 The connection structure 12 includes a first support member 123 , which is disposed on at least one side of the body 121 or the limiting assembly 122 along the first direction. The first support member 123 is disposed in the installation area 11 a and is used to support the decorative strip frame 11 .

[0096] The first support member 123 is a component that can provide a supporting force, and its specific structure is not limited. For example, it can be a support column, and the support column can be cylindrical or prismatic.

[0097] There is no limit to the number of the first support members 123. The connection structure 12 may have first support members 123 at both ends along the first direction.

[0098] It can be understood that the size of the top cover decorative strip 10 along the first direction is relatively large. Through the first support member 123, the connecting structure 12 can better support the decorative strip skeleton 11, and the risk of the connecting structure 12 shaking in the decorative strip skeleton 11 due to the accumulation of part size tolerances can be eliminated. At the same time, the size of the main body 121 and the limiting component 122 along the first direction can be appropriately reduced, the top cover decorative strip 10 uses less material and has lower production costs.

[0099] In one embodiment, please refer to Figure 1 and Figure 3The connecting structure 12 includes a second support member 124, which is arranged on at least one side of the main body 121 or the limiting assembly 122 along the first direction, and is used to support the groove wall of the groove 100a on the top of the automobile 100 facing the side of the main body 121.

[0100] The second support member 124 is a component that can provide a supporting force, and its specific structure is not limited. For example, it can be a support column, and the support column can be cylindrical or prismatic.

[0101] There is no limit to the number of the second support members 124. The connection structure 12 may have second support members 124 at both ends along the first direction, and two second support members 124 may be arranged at one end along the second direction at intervals.

[0102] After the connecting structure 12 is arranged in the groove 100a, the second supporting member 124 abuts against the groove wall of the groove 100a along the third direction. In this way, the connecting structure 12 is supported by the second supporting member 124. On the one hand, the force on the connecting structure 12 in the groove 100a is more uniform and the installation stability is better; on the other hand, the connecting structure 12 can generate an upward supporting force, and the supporting force prevents the decorative strip skeleton 11 from shaking in the groove 100a, thereby improving the stability of the top cover decorative strip 10 when assembled in the groove 100a.

[0103] In one embodiment, please refer to Figure 6 and Figure 7 The top cover decoration strip 10 includes a seal 13, which is arranged on both sides of the top cover decoration strip 10 along the second direction. The seal 13 is interference fit with the side wall of the groove 100a along the second direction to achieve the functions of sealing and beautifying the appearance.

[0104] Specifically, a groove 1121 a is formed on the second connecting section 1122 of the decorative strip skeleton 11 , and the sealing member 13 is disposed in the groove 1121 a .

[0105] The material of the sealing member 13 is not limited, and can be, for example, soft rubber.

[0106] The third aspect of the embodiment of the present application provides a connection structure 12 as in the above embodiment. Figures 3 to 5 The connecting structure 12 is used as a component of the top cover decorative strip 10 of any of the above-mentioned embodiments, and the decorative strip skeleton 11 is arranged in the groove 100a through the connecting structure 12.

[0107] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0108] The above embodiments are only preferred embodiments for fully illustrating the present application, and the protection scope of the present application is not limited thereto. Any equivalent substitution or change made by a person skilled in the art based on the present application is within the protection scope of the present application.
