Description

Technical Field

[0001] The invention belongs to the technical field of automobile water retaining strips, and in particular, relates to an insert structure for mounting and positioning an end portion of an outer water retaining strip and a vehicle. Background Art

[0002] With the continuous development of the automobile industry, the requirements for the appearance matching quality of the outer door water retaining strips at the waistline of the vehicle are also constantly increasing. Due to its strong perception, the gap surface difference between the outer water retaining strips and the door directly affects the appearance quality of the whole vehicle, which usually includes the following poor appearance quality conditions: serious Y-direction surface difference misalignment of the B-pillar position of the front and rear outer water retaining strips, serious Z-direction steps, and different X-direction gap sizes. At present, with the widespread application of bright decorative strips of outer water retaining strips, this kind of defective appearance perception is more frequent. In addition to the manufacturing accuracy of the door sheet metal itself, a large part of the cause of this problem comes from the lack of fixed structure at the end of the outer water retaining strip or the limited limit of the fixed structure.

[0003] In the existing structure, there are two main ways to clip the end of the outer water retaining strip. One is to directly use an extruded straight section to clip it to the flange stop of the sheet metal outer panel. This method has no X-axis positioning point, and employees determine whether the X-axis is assembled in place based on their subjective feelings. This installation method often cannot control the matching gap between the outer water retaining strip and the car door, and the installation accuracy and consistency cannot be guaranteed; the other is an end injection molding clip-on structure, which fixes the outer water retaining strip to the sheet metal using a clip-on structure, but this type of structure can only limit the movement in the X direction, and the outer water retaining strip cannot be controlled in the Y direction, and it is difficult to assemble.

[0004] The utility model patent with publication number CN 216424054U was disclosed on May 3, 2022, and its name is a kind of external water-cut end mounting clamping structure, which includes an external water-cut body, a door sheet metal, an external water-cut bright strip, and an external water-cut insert; a clamping structure for the external water-cut insert to be clamped is provided at the end of the door sheet metal; a matching margin for the external water-cut insert to be clamped is reserved at the end corner of the external water-cut body, the external water-cut bright strip cooperates with the external water-cut body and is clamped to the outside of the external water-cut body, and after the external water-cut body and the door sheet metal are connected at the corner, the external water-cut insert is clamped in the clamping structure. The external water-cut end mounting clamping structure also cannot solve the technical problems recorded above. Summary of the invention

[0005] The purpose of the present invention is to address the deficiencies of the prior art and to provide an insert structure for mounting and positioning the end of an outer water retaining strip, which is easy to install, ensures proper assembly, and improves the matching quality between the outer water retaining strip and a counterpart.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] The insert structure for installing and positioning the end of the outer water retaining strip includes a door sheet metal and a door window frame.

[0011] The cross section of the clamping block is a cross-shaped structure, and the limiting hole is a square hole.

[0012] The boss is a columnar structure, and the positioning groove is a semicircular structure.

[0013] The axis of the positioning hole and the axis of the limiting hole are arranged in parallel.

[0014] The boss and the block are both located on the inner side of the outer water retaining strip.

[0015] The boss and the clamping block are integrally injection-molded with the outer water retaining strip.

[0016] The vehicle comprises the above-mentioned insert structure for mounting and positioning the end of the outer water retaining strip.

[0017] The technical effect of the present invention is as follows: the insert structure for installing and positioning the end of the outer water retaining strip of the present invention is adopted, and the insert structure is set on the end of the outer water retaining strip to realize the installation and positioning of the end of the outer water retaining strip, and a clamping block for fixing the outer water retaining strip in the X / Z direction is arranged on the limiting portion to ensure the gap surface difference between the end of the outer water retaining strip and the counterpart; a boss for screw connection in the Y direction is arranged on the insert, and the screw is arranged inside the vehicle door to ensure that the outer water retaining strip is fixed and does not fall off, and effectively ensure the surface difference between the outer water retaining sealing strip and the counterpart in the Y direction; thereby achieving effective positioning of the end of the outer water retaining strip in the X / Y / Z directions, ensuring the matching gap and surface difference with the counterpart, and making the assembly simple and easy for employees to operate, thereby improving the assembly efficiency; solving the problems of unqualified gap and surface difference after matching caused by low positioning accuracy and difficult installation and matching in the traditional structure, thereby ensuring the installation quality of the outer water retaining strip.

[0026] The specific implementation methods of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and facilitating their implementation.

[0027] like Figures 1 to 6 As shown, the insert structure for positioning the end of the outer water retaining strip includes a door sheet metal 2 and a door window frame 3. The two ends of the outer water retaining strip 1 are provided with a limit portion 4, and the limit portion 4 is provided with a first limit member and a second limit member. The first limit member includes a boss 6, and the second limit member includes a clamping block 7. The limit insert is formed by injection molding at the corner 5 at the end of the outer water retaining strip 1. The limit insert is set at the end of the outer water retaining strip 1. The two limit inserts constitute two positioning forms, and the displacement of the outer water retaining strip 1 on the edge of the sheet metal stop is limited by screw connection and clamping structure respectively, and the displacement of the outer water retaining strip 1 in the X, Y and Z directions is limited by working together, and the assembly form is simple and the assembly time is less.

[0028] like Figures 3 to 6As shown, the door window frame 3 is provided with a positioning hole 9, and the end of the boss 6 abuts against the outer side of the positioning hole 9; the door sheet metal 2 is provided with a limiting hole 10, and the clamping block 7 is clamped with the limiting hole 10. The boss 6 abuts against the positioning hole 9 to limit the Y-direction movement of the outer water retaining strip 1, and is fastened to the boss 6 by screws to form a stable fixation of the outer water retaining strip 1. The second limit member adopts a snap-on installation form, which is simple to operate, has high assembly efficiency, and provides a reliable connection effect. The second limit member is a cross-shaped boss 6 integrated on the limit part 4, and a limit hole 10 is provided on the door sheet metal 2 along the axial direction of the second limit member. The effective area at the end of the cross-shaped boss 6 on the second limit member is smaller than the effective area at the bottom, that is, the cross-shaped boss 6 shows a trend of changing from narrow to wide, and the corresponding effective length and width of the limit hole 10 are slightly smaller than the effective length and width of the bottom of the cross-shaped boss 6. This structural form is convenient for the operator to insert the second limit member into the limit hole 10 conveniently during assembly, and to resist snap-connection between the second limit member and the inner wall of the limit hole 10 along the installation direction, thereby limiting the displacement of the first limit part 4 in the Z and X directions of the door, preventing the end from warping due to improper assembly, and avoiding the problem of inaccurate positioning of the outer water retaining strip 1 with the end of the door when the B-pillar end is used as the positioning reference.

[0029] like Figure 1 and Figure 5 As shown, a connection hole 11 is provided in the middle of the boss 6, and the diameter of the connection hole 11 is smaller than the diameter of the positioning hole 9, and the diameter of the positioning hole 9 is smaller than the outer diameter of the boss 6. The above structure enables the boss 6 to form an abutment effect with the edge of the positioning hole 9, without affecting the connection of the screws. The first limiting member is a cylindrical boss 6 integrated on the limiting part 4, and a positioning groove 8 is provided on the stop surface of the door sheet metal 2 along the central axis direction of the cylindrical boss 6, and the positioning groove 8 and the limiting hole 10 are arranged at intervals along the stop of the door sheet metal 2. The positioning groove 8 transitions downward along the door sheet metal 2 to form a semicircular shape, and the effective radius of the positioning groove 8 is larger than the first limiting member. The groove wall of the positioning groove 8 and the first limiting member are set with a gap of 1mm. Its main function is to facilitate the operator to quickly locate and assemble during installation. At the same time, a positioning hole 9 is provided on the door window frame 3 in close contact with the positioning groove 8. The aperture of the positioning hole 9 is smaller than the outer diameter of the boss 3 and larger than the inner diameter of the connecting hole 11, and the end of the cylindrical boss 6 is resisted and matched with the positioning hole 9, and the two are connected with screws. It can be foreseen that the operator will first identify the positioning groove 8, align the first limit member with the positioning groove 8, and tighten it with screws. This connection method can limit the external water retaining strip 1 on the vehicle door, and can adjust the tightness of the end and the vehicle door in the Y direction.

[0030] like Figure 1 and Figure 5As shown, a positioning groove 8 is provided on the edge of the door sheet metal 2, and the positioning groove 8 is located on one side of the boss 6. The connection hole 11 serves as a threaded mating part of the screw, and the screw passes through the positioning hole 9 from the inner side of the door window frame 3 and is connected to the connection hole 11, achieving a hidden connection effect, limiting the Y-direction movement of the outer water retaining strip 1. In addition, the gap between the outer water retaining strip 1 and the door sheet metal 2 can be controlled by adjusting the preload force. Since the glass is located between the outer water retaining strip 1 and the inner water retaining strip, the clamping force between the glass and the screw can be adjusted to the maximum by adjusting the tightness of the screw, thereby ensuring the cleanliness of the glass during the lifting process.

[0031] like Figure 1 As shown, the boss 6 is a columnar structure, and the positioning groove 8 is a semicircular structure. The boss 6 is designed as a columnar structure, which is convenient for adapting to the semicircular positioning groove 8, and the positioning is convenient, so that the two limiters can be quickly positioned to the mounting holes on the door sheet metal 2. The positioning groove 8 is designed as a semicircular shape to make the edge transition of the door sheet metal 2 smooth and reduce stress concentration.

[0032] like Figure 2 and Figure 3 As shown, the cross section of the clamping block 7 is a cross-shaped structure, and the limiting hole 10 is a square hole. The second limiting member is in the shape of a cross-shaped boss 6 structure, the end length and width of which are smaller than the length and width of the end connected to the outer water retaining strip 1, and the outer diameter of the boss 6 forms a trend of gradually increasing, presenting a structure that is narrow at the bottom and wide at the top. The limiting hole 10 is formed into a rectangular square hole by punching, and its length and width are greater than the maximum length and width of the end of the second limiting member, and smaller than the effective length and width of the end connected to the outer water retaining strip 1. The second limiting member is fixed on the door by interfering the cross-shaped convex structure with the limiting hole 10 to block and limit, and the clamping firmness is higher. The reliable clamping of the cross-shaped boss 6 and the limiting hole 10 enables the outer water retaining strip 1 to have a fixing effect in the X and Z directions.

[0033] like Figure 3 As shown, the axis of the positioning hole 9 is arranged parallel to the axis of the limiting hole 10. The above structure facilitates the installation process of the outer water retaining strip 1, and the operator only needs to apply force from a single direction to complete the preliminary installation of the outer water retaining strip 1.

[0034] like Figure 1 As shown, the boss 6 and the block 7 are both located on the inner side of the outer water retaining strip 1. With the above structure, the boss 6 and the block 7 will not affect the appearance of the outer water retaining strip 1.

[0035] The boss 6 and the block 7 are integrally injection molded with the outer water retaining strip 1. The boss 6 and the block 7 are designed by injection molding, which can simplify the design difficulty, ensure the consistency of the quality of the outer water retaining strip 1, improve production efficiency and reduce production costs.

[0036] The vehicle includes the above-mentioned insert structure for installing and positioning the end of the outer water retaining strip. The outer water retaining strip 1 includes the outer water retaining strip 1 body, the corners 5 distributed at the two ends of the outer water retaining strip 1 and the limit part 4, all of which are connected to the outer water retaining strip 1 body by injection molding, and the outer water retaining strip body is assembled with the stop edge of the door sheet metal 2 through its clamping structure. The limit parts 4 are provided at the corners 5 at both ends of the outer water retaining strip 1, and the first limit part and the second limit part are arranged on the limit part 4 at intervals. The axial direction of the first limit part and the second limit part is perpendicular to the stop table of the door sheet metal 2, which ensures that the outer water retaining strip 1 is assembled in place and avoids the problem of poor matching effect of the gap surface difference between it and the counterpart on the door, so that the outer water retaining strip 1 mainly plays the functions of reliable dust removal, noise prevention, glass wiping, and clamping glass lifting in actual application.

[0037] The matching holes of the door sheet metal 2 of the outer water retaining strip limiting structure are arranged at the B-pillar end and the C-pillar end, and can also be arranged at the A-pillar end. A plurality of mounting holes that cooperate with the boss 6 and the block 7 are arranged on the door sheet metal 2. The outer water retaining strip 1 of the rear door is described as an example. A positioning groove 8 and a limiting hole 10 are provided at the B-pillar end of the door sheet metal 2. The positioning groove 8 and the limiting hole 10 extend along the stop of the door sheet metal 2 toward the rear side of the vehicle body and are arranged at intervals. Similarly, a positioning groove 8 and a limiting hole 10 are also provided at the C-pillar end of the door sheet metal 2. A limiting portion 4 is provided at the C-pillar end of the outer water retaining strip 1, and its main function is to cooperate with its B-pillar end to limit the Y direction of the outer water retaining strip 1 to prevent the end of the outer water retaining strip 1 from curling up at the C-pillar end. The door window frame 3 is provided with a positioning hole 9 corresponding to the first limiting piece, and the positioning groove 8 is located between the first limiting piece and the first positioning hole 9. The extension height of the first limiting piece stops between the sheet metal thickness of the positioning groove 8. The first positioning hole 9 is arranged zero-closely with the first positioning groove 8. Similarly, a positioning hole 9 is also provided correspondingly at the other end of the door window frame 3.

[0038] like Figure 3 , Figure 5 and Figure 6 As shown, the installation method of the outer water retaining strip 1 is as follows: first, pre-position the B-pillar end of the outer water retaining strip 1 and the B-pillar end of the vehicle door, respectively place the boss 6 in the positioning groove 8, and also place the boss 6 at the C-pillar end in the positioning groove 8, and pass the second limiting piece through the limiting hole 10, and at the same time, press the outer water retaining strip 1 downward along the edge of the sheet metal stop to assemble, and at the same time, press the second limiting piece and the limiting hole 10 against each other while pressing downward to assemble, and when the assembly is completely to the bottom, tighten the positioning holes 9 connecting the B-pillar end and the C-pillar end to the first limiting piece with screws, and since the screws are located inside the vehicle door, they also play an anti-theft role to a certain extent.

[0039] Through the description of the specific implementation methods of the present invention, the first limiting member can limit the Y direction of the outer water retaining strip 1 as a whole, and the second limiting member can limit the X and Z directions of the outer water retaining strip 1 by locking. The above installation form solves the problem that the end of the outer water retaining strip 1 cannot be fixed, and the end is easily warped due to improper installation. The outer water retaining strip can be firmly fixed on the vehicle door through the positioning and limiting structure of the end. At the same time, the problem of inaccurate end positioning during installation by the operator is solved, which greatly improves the consistency of assembly and is conducive to the improvement of the refined appearance of the product.

[0040] The insert structure for installing and positioning the end of the outer water retaining strip is provided with an insert structure on the end of the outer water retaining strip 1 to realize the installation and positioning of the end of the outer water retaining strip, and a clamping block 7 for fixing the outer water retaining strip 1 in the X / Z direction is arranged on the limiting portion 4 to ensure the gap surface difference between the end of the outer water retaining strip and the counterpart; a boss 6 for Y-direction connection with a screw is arranged on the insert, and the screw is arranged inside the vehicle door to ensure that the outer water retaining strip is fixed and does not fall off, and effectively ensure the surface difference between the outer water retaining sealing strip and the counterpart in the Y direction; thereby achieving effective positioning of the end of the outer water retaining strip in the X / Y / Z directions, ensuring the matching gap and surface difference with the counterpart, and making the assembly simple and easy for employees to operate, thereby improving the assembly efficiency; solving the problems of low positioning accuracy and difficult installation and matching in the traditional structure, resulting in unqualified gap and surface difference after matching, and ensuring the installation quality of the outer water retaining strip 1.

[0041] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
