Description
Technical Field
[0001] The present application relates to the technical field of automobile decorative part assembly, and in particular to an automobile decorative part assembly fixing structure. Background Art
[0002] When assembling and connecting automobile decorative parts, some automobile decorative parts will have protruding mounting columns, while others will have corresponding mounting holes for the mounting columns to slide through, so as to limit the horizontal position between multiple automobile decorative parts, and then they are connected to the mounting columns by bolt threads or fixed by ultrasonic welding.
[0003] Since there is a gap between the mounting hole and the mounting column, there is a possibility of deviation or warping during the installation process. Therefore, in the prior art, some of the mounting positions between the assembled automobile decorative parts need to be manually pressed and then fixed, or a fixing jig is developed to place multiple automobile decorative parts in the jig in turn, and then the relative positions are fixed using a quick clamp.
[0004] However, when fixing by a jig, it takes a certain amount of time to open and close the quick clamp, which may reduce the assembly efficiency of the automobile decorative parts, so further improvement is needed. Utility Model Content
[0005] In order to reduce the impact on the assembly efficiency of automobile decorative parts, the present application provides an automobile decorative part assembly and fixing structure.
[0006] The present application provides an automobile decorative parts assembly and fixing structure, which adopts the following technical solutions:
[0007] A car decorative part assembly and fixing structure is arranged between two car decorative parts, the two car decorative parts are respectively a first decorative part and a second decorative part, including a mounting column arranged on the first decorative part, the second decorative part is penetrated by a mounting hole for the mounting column to pass through, the side wall of the mounting column is protrudingly provided with a limit card point, the limit card point is elastic, the limit card point is provided with a third guide surface near the upper surface of the mounting column, the width of the lower end of the limit card point is greater than the width of the third guide surface, and a space for the second decorative part to be placed is reserved between the limit card point and the first decorative part.
[0008] By adopting the above technical solution, a third guide surface is provided, and when the mounting hole is aligned with the mounting column, the third guide surface is followed, and since the limit card point is elastic, pressure is applied to the limit card point during the process of inserting the mounting column into the mounting hole. When the second decorative piece slides to the space left between the limit card point and the first decorative piece, the limit card point is reset under its own elastic force. Since the width of the lower end of the limit card point is greater than the width of the third guide surface, the possibility of the second decorative piece being lifted up relative to the first decorative piece under the influence of external force is limited, thereby reducing the time spent on fixing the first decorative piece and the second decorative piece by clamps, thereby relatively reducing the impact on the assembly efficiency of the automobile decorative pieces.
[0009] Preferably, the limit clamping point abuts against an upper surface of the second decorative element.
[0010] By adopting the above technical solution, the limit card point is abutted against the upper surface of the second decorative piece, which can further reduce the possibility of the second decorative piece sliding in the height direction relative to the first decorative piece, thereby improving the fixing effect of the limit card point on the first decorative piece and the second decorative piece.
[0011] Preferably, a limit strip is protruding from the side wall of the mounting post, the height of the limit strip is lower than the height of the mounting post, a second guide surface is formed on the upper end surface of the limit strip, and the limit strip abuts against the side wall of the mounting hole.
[0012] By adopting the above technical solution, a limit strip is set, and a second guide surface is opened on the upper end surface of the limit strip. Since the limit strip abuts against the side wall of the mounting hole, the possibility of horizontal movement of the first decorative part and the second decorative part is reduced, thereby reducing the possibility of horizontal sliding during the fixing process to affect the assembly efficiency.
[0013] Preferably, the limit clamping point and the limit strip are staggered.
[0014] By adopting the above technical solution, the limit clamping points and the limit strips are staggered to reduce the difficulty of processing when the limit clamping points and the limit strips are located in the same vertical direction.
[0015] Preferably, a plurality of the limiting bars are arranged at intervals around the axis of the mounting column.
[0016] By adopting the above technical solution, the horizontal limitation of the second decorative component can be improved, and the spacing between the mounting holes and the mounting columns can be distributed more evenly, thereby reducing the possibility of uneven welding during ultrasonic welding.
[0017] Preferably, a slide groove is provided on the side wall of the mounting column, the limit clamping point is slidably connected to the slide groove, an elastic member is provided in the slide groove, and the elastic member forces the limit clamping point to move in a direction away from the slide groove.
[0018] By adopting the above technical solution, when the limit card point is squeezed, when the squeezing force is greater than the elastic member, the limit card point retreats into the slide groove, and when the second decorative member slides to the space left between the limit card point and the first decorative member, the squeezing force on the limit card point disappears, and under the elastic force of the elastic member, it moves in the direction away from the slide groove to limit the sliding of the second decorative member in the height direction.
[0019] Furthermore, by providing an elastic member and setting the limit clamping point in a sliding manner, the limit clamping point is also elastic, so that the hardness of the limit clamping point is higher, thereby improving the limit effect on the second decorative member. In the actual assembly process, the first decorative member and the second decorative member may be misaligned, so it is also convenient to apply pressure to the elastic member to disassemble the first decorative member and the second decorative member.
[0020] Preferably, a plurality of the limit clamping points are arranged at intervals around the axis of the mounting column.
[0021] By adopting the above technical solution and providing a plurality of limit points, the fixing effect between the first decorative piece and the second decorative piece can be improved.
[0022] Preferably, the elastic member is a spring or an elastic pad.
[0023] By adopting the above technical solution, the elasticity of the spring or elastic pad itself is used to force the limit card point to move in the direction away from the slide groove, and the cost and weight of the elastic member are relatively low, which adds less weight and cost between the first decorative member and the second decorative member.
[0024] In summary, the utility model has the following beneficial effects:
[0025] 1. By setting a limit point, the possibility of the second decorative part being lifted relative to the first decorative part under the influence of external force is limited, thereby reducing the time spent on fixing the first decorative part and the second decorative part by clamps, thereby relatively reducing the impact on the assembly efficiency of the automobile decorative parts.
[0026] 2. By providing a limit strip, the possibility of horizontal movement of the first decorative member and the second decorative member is reduced, so as to reduce the possibility of horizontal sliding during the fixing process to affect the assembly efficiency.
[0027] 3. By providing the elastic member and the slide groove, the installation column can be easily slidably inserted into the installation hole, and it is also convenient to remove the wires and reinstall when an installation error occurs. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is combined with Figure 1-6 , further details of this application are given.
[0036] The embodiment of the present application discloses an automobile decorative part assembly and fixing structure.
[0037] Embodiment 1:
[0038] A car decoration assembly fixing structure, referring to Figure 1 , Figure 2 , arranged between two automobile decorative parts, the two automobile decorative parts are respectively a first decorative part 1 and a second decorative part 2. It should be noted that the first decorative part 1 and the second decorative part 2 are both plastic products.
[0039] Reference Figure 1 , Figure 3 A car decorative part assembly and fixing structure specifically includes a mounting column 3 arranged on a first decorative part 1, a plurality of mounting columns 3 are arranged at intervals along the edge of the first decorative part 1, a first guide surface 31 is provided on the upper end surface of the mounting column 3, and the first guide surface 31 is arranged in a ring shape around the axis of the mounting column 3, a second decorative part 2 is penetrated by a mounting hole 4 for the mounting column 3 to pass through, and a plurality of mounting holes 4 are correspondingly arranged.
[0040] In order to limit the relative sliding of the first decorative part 1 and the second decorative part 2 in the horizontal direction, a limit strip 5 is protruded from the side wall of the mounting column 3. The height of the limit strip 5 is lower than the height of the mounting column 3 and is arranged close to the lower end of the mounting column 3. A second guide surface 51 is provided on the upper end surface of the limit strip 5, and the limit strip 5 abuts against the side wall of the mounting hole 4.
[0041] A limit clamping point 6 is protruded from the side wall of one of the mounting posts 3. In this embodiment, the limit clamping point 6 is elastic, and a third guide surface 61 is provided on the upper end surface of the limit clamping point 6 close to the mounting post 3. The width of the third guide surface 61 gradually increases in the direction away from the upper end surface of the mounting post 3, so that the width of the lower end of the limit clamping point 6 is greater than the width of the third guide surface 61, and a space for placing the second decorative part 2 is reserved between the limit clamping point 6 and the first decorative part 1. It should be noted that in this embodiment, the limit clamping point 6 and the limit strip 5 are staggered.
[0042] It should be noted that since the first decorative piece 1 and the second decorative piece 2 are both plastic products with a certain deformation ability, the limit card point 6 has a certain elasticity. Under the action of a large extrusion force, the mounting column 3 provided with the limit card point 6 can be slid through the mounting hole 4, and the first decorative piece 1 and the second decorative piece 2 can be fixed by the limit card point 6 provided on one of the mounting columns 3, which can relatively reduce the increase in cost and the increase in weight between automobile decorative parts.
[0043] The implementation principle of an automobile decorative part assembly and fixing structure of an embodiment of the present application is as follows: by providing a third guide surface 61, when the mounting hole 4 is aligned with the mounting column 3, the third guide surface 61 is followed, and since the limit clamping point 6 is elastic, during the process of inserting the mounting column 3 into the mounting hole 4, pressure is applied to the limit clamping point 6. When the second decorative part 2 slides to the space left between the limit clamping point 6 and the first decorative part 1, the limit clamping point 6 is reset under its own elastic force. Since the width of the lower end of the limit clamping point 6 is greater than the width of the third guide surface 61, the possibility of the second decorative part 2 being lifted up relative to the first decorative part 1 under the influence of external force is limited, thereby reducing the time spent on fixing the first decorative part 1 and the second decorative part 2 by clamps, thereby relatively reducing the impact on the assembly efficiency of the automobile decorative parts.
[0044] As it slides away from the limit clamping point 6, the second guide surface 51 on the limit strip 5 guides the inner surface of the first decorative component 1 located in the mounting hole 4. As it is pressed, the limit strip 5 is brought into contact with the side wall of the mounting hole 4 for limiting.
[0045] Embodiment 2:
[0046] Reference Figure 4The difference from Example 1 is that a plurality of limiting strips 5 are arranged at intervals around the axis of the mounting column 3. In this embodiment, two limiting strips 5 are specifically arranged to improve the horizontal limitation of the second decorative member 2, and to make the spacing between the mounting hole 4 and the mounting column 3 more evenly distributed, thereby reducing the possibility of uneven welding during ultrasonic welding.
[0047] Reference Figure 5 In this embodiment, the limit card point 6 abuts against the upper surface of the second decorative member 2, which can further reduce the possibility of the second decorative member 2 sliding in the height direction relative to the first decorative member 1, so as to improve the fixing effect of the limit card point 6 on the first decorative member 1 and the second decorative member 2.
[0048] Embodiment 3:
[0049] Reference Figure 6 The difference from Example 1 is that a slide groove 32 is provided on the side wall of the mounting column 3, and the limit card point 6 is slidably connected to the slide groove 32. An elastic member 7 is provided in the slide groove 32, and the elastic member 7 forces the limit card point 6 to move in a direction away from the slide groove 32. In this embodiment, the elastic member 7 can be a spring or an elastic pad, specifically a spring.
[0050] The implementation principle of an automobile decorative part assembly and fixing structure of an embodiment of the present application is as follows: as the mounting column 3 is inserted into the mounting hole 4, the inner wall of the mounting hole 4 first abuts against the third guide surface 61, and as the second decorative part 2 moves toward the first decorative part 1, the limit card point 6 is squeezed. When the squeezing force is greater than the elastic member 7, the limit card point 6 is made to retreat into the slide groove 32. When the second decorative part 2 slides to the space left between the limit card point 6 and the first decorative part 1, the squeezing force on the limit card point 6 disappears, and under the elastic force of the elastic member 7, it moves in the direction away from the slide groove 32 to limit the sliding of the second decorative part 2 in the height direction.
[0051] Furthermore, by providing the elastic member 7 , when there is a possibility of misalignment between the first decorative member 1 and the second decorative member 2 , it is also convenient to apply pressure to the elastic member 7 so as to disassemble the first decorative member 1 and the second decorative member 2 and then reassemble them.
[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
