Abstract
Description
Technical Field
[0001] The present application relates to the technical field of automobile parts, and in particular to a buckle structure applied to decorative strips of vehicle door and window frames. Background Art
[0002] Currently, the window frame decorative strips of vehicle doors are mainly arranged on end clips at both ends, and then the end clips are locked on the vehicle door sheet metal by self-tapping screws.
[0003] However, the existing end clips have the following two problems: (1) The existing end clips have mounting holes with through-hole structures. When self-tapping screws are used to lock the end clips with the door sheet metal, the self-tapping screws are prone to slipping in the mounting holes; (2) Before the existing end clips are assembled with the window frame decorative strips, glue needs to be applied to the end surface of the end clips away from the through-holes. During the assembly process of the window frame decorative strips and the end clips, the end of the window frame decorative strips will gradually squeeze out the glue, resulting in the glue being concentrated only around the end of the window frame decorative strips when the window frame decorative strips are fully assembled on the end clips, thereby causing the glue to overflow from the end of the window frame decorative strips and the window frame decorative strips to be poorly bonded to the end clips. Utility Model Content
[0004] In response to the above technical problems, the present application provides a snap-on structure applied to vehicle door and window frame decorative strips, aiming to solve the problems of easy thread slippage, glue overflow and weak bonding in the existing snap-on structure described in the background technology.
[0005] The present application provides a clip structure for a vehicle door window frame decorative strip, including a clip and a fastener, the clip forming a plug-in portion for the window frame decorative strip to be sleeved, the plug-in portion being provided with a limiting groove and an adhesive hole, the fastener being used to cooperate with the limiting groove to fix the clip on the vehicle door sheet metal, wherein the fastener includes a connecting rod and a locking portion, the locking portion being arranged at one end of the connecting rod, and when the fastener is in a state of cooperation with the limiting groove, the end face of the connecting rod away from the locking portion presses against the bottom surface of the limiting groove; the adhesive hole is used for allowing glue to be injected into the adhesive space formed between the window frame decorative strip and the plug-in portion when the window frame decorative strip is sleeved on the plug-in portion.
[0006] Optionally, the bottom surface of the limiting groove is configured to match the shape of the end surface of the fastener connecting rod.

[0010] Optionally, there are multiple bonding holes, and the multiple bonding holes are opened on the plug-in portion around the limiting groove.
[0011] Optionally, the diameter of the bonding hole is 0.8 mm to 1.2 mm.
[0012] Optionally, the fastener further includes a guide portion, which is provided at an end of the plug-in portion facing the window frame decorative strip, and is used to guide the window frame decorative strip to be sleeved on the plug-in portion.
[0013] Optionally, the guide portion has a guide side surface close to the window frame decorative strip and a guide end surface facing the window frame decorative strip, and the guide side surface is inclined to the guide end surface at a preset angle.
[0014] Optionally, the length of the guide portion is 4 to 8 mm, and the preset angle is 70° to 85°.
[0015] The present application provides a limiting groove and an adhesive hole on the plug-in part. On the one hand, when the fastener fixes the clip to the door sheet metal through the limiting groove, the end face of the connecting rod presses against the bottom face of the limiting groove, thereby solving the problem of thread slippage.

[0025] Please refer to Figure 1 The snap-fit structure includes a snap-fit component 10 and a fastener 20. The snap-fit component 10 is formed with an inserting portion 11 for the window frame decorative strip 80 to be sleeved. In the illustrated structure, the window frame decorative strip 80 is sleeved on the inserting portion 11 for illustration. The snap-fit component 10 extends along a first direction to form the inserting portion 11. After the window frame decorative strip 80 is sleeved, the first direction corresponds to the length direction of the window frame decorative strip 80. A limiting groove 112 and an adhesive hole 113 are provided on the first surface of the inserting portion 11. The limiting groove 112 is a blind hole, and the adhesive hole 113 is a through hole. After the window frame decorative strip 80 is sleeved, the first surface is the surface facing away from the window frame decorative strip 80.
[0026] Please refer to Figure 1 and Figure 2 The fastener 20 is used to cooperate with the limiting groove 112 to fix the clip 10 to the vehicle door sheet metal 90. The fastener 20 includes a connecting rod 21 and a locking portion 22. The locking portion 22 is provided at one end of the connecting rod 21. When the fastener 20 is in cooperation with the limiting groove 112, the end surface of the connecting rod 21 away from the locking portion 22 abuts against the bottom surface of the limiting groove 112. Specifically, in actual implementation, after the window frame decorative strip 80 is sleeved on the plug-in portion 11, the plug-in portion 11 and the vehicle door sheet metal 90 need to be fixed to each other. In this embodiment, the fastener 20 is a bolt. The connecting rod 21 of the fastener 20 sequentially passes through the hole of the vehicle door sheet metal 90 and the limiting groove 112, and the locking portion 22 abuts against the notch of the limiting groove 112 to achieve the purpose of fixing the clip 10 to the vehicle door sheet metal 90.
[0027] It is understandable that the mounting hole of the existing snap-fit structure in the background art is a through-hole structure. When the self-tapping screw is locked in the through-hole structure, the end face of the screw of the self-tapping screw cannot exert force, which easily causes the problem of thread slippage. In the present application, when the fastener 20 is locked in the limiting groove 112, the bottom surface of the limiting groove 112 can press against the end face of the connecting rod 21 and provide a point of force for it. In this way, each surface of the connecting rod 21 of the fastener 20 is covered in the limiting groove 112, that is, the connecting rod 21 of the fastener 20 has a point of force in all directions, thereby solving the problem of thread slippage.
[0028] Optionally, the fasteners may be, for example, bolts, screws, rivets, etc., which are not limited here.
[0029] As one embodiment, the bonding holes 113 are used to allow glue to be injected into the bonding space formed between the window frame decorative strip 80 and the plug-in portion 11 when the window frame decorative strip 80 is sleeved on the plug-in portion 11. Specifically, in this embodiment, after the window frame decorative strip 80 is sleeved on the plug-in portion 11, the window frame decorative strip 80 can be laid flat, and glue can then be injected into the bonding space formed between the window frame decorative strip 80 and the plug-in portion 11 through the bonding holes 113. In this way, the glue can be evenly applied between the window frame decorative strip 80 and the plug-in portion 11, solving the problems of glue overflow and weak bonding.
[0030] Optionally, the bottom surface of the limiting groove 112 is configured to match the shape of the end surface of the connecting rod 21. Specifically, in this embodiment, the bottom surface of the limiting groove 112 is configured to match the shape of the end surface of the connecting rod 21. Thus, when the fastener 20 is locked in the limiting groove 112, the end surface of the connecting rod 21 can completely abut against the bottom surface of the limiting groove 112, significantly increasing the force provided by the limiting groove 112 to the fastener 20. Exemplarily, the shapes of the bottom surface of the limiting groove 112 and the end surface of the connecting rod 21 can be, for example, truncated cone, trapezoidal, conical, etc., which are not limited here.
[0031] Optionally, the shape of the bottom surface of the limiting groove 112 and the end surface of the connecting rod 21 is conical, and the taper depth (a) of the limiting groove 112 is 2.3mm to 2.7mm. Specifically, in this embodiment, the fastener 20 can be, for example, a self-tapping screw, and the shape of the end surface of the connecting rod 21 is conical, that is, the bottom surface of the limiting groove 112 is adaptively also conical. Furthermore, by limiting the taper depth (a) of the limiting groove 112 to 2.3mm to 2.7mm, it is possible to obtain a better locking effect between the fastener 20 and the limiting groove 112 without affecting the thickness of the fastener 10. Among them, the taper depth (a) of the limiting groove 112 can be, for example, 2.3mm, 2.5mm, 2.6mm, 2.7mm, etc., which is not limited here.
[0032] Optionally, the inner diameter (b) of the limiting groove 112 is 1.8mm to 2.2mm, and the diameter (D) of the connecting rod 21 is 2.8mm to 3.2mm. Specifically, in this embodiment, under the premise of limiting the taper depth of the limiting groove 112 as mentioned above, limiting the inner diameter (b) of the limiting groove 112 to 1.8mm to 2.2mm and the diameter (D) of the connecting rod 21 to 2.8mm to 3.2mm can achieve interference fit between the fastener 20 and the limiting groove 112, thereby further improving the locking effect of the fastener 20 and the limiting groove 112. Among them, the inner diameter (b) of the limiting groove 112 can be, for example, 1.8mm, 1.9mm, 2.0mm, 2.2mm, etc., and the diameter (D) of the connecting rod 21 can be, for example, 2.8mm, 3.0mm, 3.2mm, etc., and are not limited here.
[0033] Optionally, the taper depth (a) of the limiting groove 112 is 2.5 mm, the inner diameter (b) of the limiting groove 112 is 2 mm, and the diameter (D) of the connecting rod 21 is 3 mm. Specifically, in this embodiment, when the taper depth (a) of the limiting groove 112 is 2.5 mm, the inner diameter (b) of the limiting groove 112 is 2 mm, and the diameter (D) of the connecting rod 21 is 3 mm (for example, it can be an M3 self-tapping screw), the fastener 20 and the limiting groove 112 can achieve a relatively optimal locking effect.
[0034] Optionally, there are multiple bonding holes 113, and multiple bonding holes 113 are opened on the plug-in portion 11 around the limiting groove 112. Specifically, in this embodiment, multiple bonding holes 113 are opened on the plug-in portion 11, and multiple bonding holes 113 are opened on the plug-in portion 11 around the limiting groove 112. In the illustrated structure, there are four bonding holes 113, and the four bonding holes 113 are evenly distributed at the four corners of the plug-in portion 11. When performing the glue injection process, glue is injected into the four bonding holes 113 distributed in different areas of the plug-in portion 11 respectively, so as to achieve the effect of more evenly coating the glue in the bonding space formed by the window frame decorative strip 80 and the plug-in portion 11, further avoiding the problems of glue overflow and weak bonding.
[0035] Optionally, the diameter (d) of the bonding hole 113 is 0.8 mm to 1.2 mm. Specifically, in this embodiment, by limiting the diameter (d) of the bonding hole 113 to 0.8 mm to 1.2 mm, it is possible to ensure that the glue injection tool can relatively easily extend through the bonding hole 113 into the bonding space formed by the window frame decorative strip 80 and the plug-in portion 11, and to prevent glue from overflowing from the bonding hole 113 during the glue injection process. The diameter (d) of the bonding hole 113 can be, for example, 0.8 mm, 0.9 mm, 1 mm, 1.2 mm, etc., and is not limited here.
[0036] Please refer to Figure 1 and Figure 3 The fastener 10 further includes a guide portion 12, disposed at one end of the inserting portion 11, for guiding the window frame decorative strip 80 in its insertion onto the inserting portion 11. Specifically, in the illustrated structure, the guide portion 12 is further disposed on the right end surface of the inserting portion 11. It will be appreciated that the provision of the guide portion 12 facilitates the insertion of the window frame decorative strip 80 onto the inserting portion 11, thereby improving the efficiency of assembly.
[0037] In one embodiment, the guide portion 12 may be evenly converged from the periphery toward the center to form a trapezoidal body, making it easier to assemble with the window frame decorative strip 80 .
[0038] Optionally, the guide portion 12 includes a guide side surface 121 and a guide end surface 123, and the guide side surface 121 is inclined at a preset angle to the guide end surface 123. Specifically, in this embodiment, the fastener 10 has a first side surface and a second side surface that are arranged opposite to each other, and the limiting groove 112 is provided on the first side surface. The edges of the first side surface and the second side surface are close to each other and extend obliquely to form the guide side surface 121, and the two ends of the guide end surface 123 are respectively connected to the two guide side surfaces 121 to form the guide portion 12. The guide side surface 121 is inclined at a preset angle to the guide end surface 123, so that when the end of the window frame decorative strip 80 is docked with the guide portion 12, the inclined guide end surface 123 can more easily make the window frame decorative strip 80 fit on the plug-in portion 11, further improving the efficiency of assembling the two.
[0039] Optionally, the length (c) of the guide portion 12 is 4 to 8 mm, and the preset angle (α) is 70° to 85°. Specifically, in this embodiment, by limiting the length (c) of the guide portion 12 to 4 to 8 mm and the preset angle (α) to 70° to 85°, the window frame decorative strip 80 can be docked with the guide portion 12 in the most convenient and quick manner, thereby quickly completing the assembly process between the window frame decorative strip 80 and the fastener 10, and the assembly efficiency can reach a relatively high value. Among them, the length (c) of the guide portion 12 can be, for example, 4 mm, 5 mm, 6 mm, 8 mm, etc., and the preset angle (α) can be, for example, 70°, 71°, 73°, 75°, 77°, 78°, 80°, 82°, 84°, 85°, etc., which are not limited here.
[0040] Please refer to Figure 2 In one embodiment, when the window frame trim strip 80 is mounted on the inserting portion 11, a gap of a certain thickness (e) is reserved between the bottom of the bonding hole 113 and the window frame trim strip. The thickness of the gap (e) is limited to 0.2mm to 0.5mm. This can increase the speed of glue flowing into the bonding space and improve the efficiency of the bonding process. The thickness of the gap (e) can be, for example, 0.2mm, 0.3mm, 0.5mm, etc., and is not limited here.
[0041] The present application provides a limiting groove and an adhesive hole on the plug-in part. On the one hand, when the fastener fixes the clip to the door sheet metal through the limiting groove, the end face of the connecting rod presses against the bottom face of the limiting groove, thereby solving the problem of thread slippage. On the other hand, after the window frame decorative strip is sleeved on the plug-in part, glue is injected into the adhesive space through the adhesive hole, thereby solving the problems of glue overflow and weak bonding.
[0042] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the appended claims.
