Description

Technical Field

[0001] The utility model relates to the technical field of vehicle door component assembly, in particular to a concealed vehicle door outer opening handle assembly tool. Background Art

[0002] As the material living standard and quality of life continue to improve, customers pay more and more attention to the first sensory impression of automobile products when purchasing. The hidden door handle area is one of the areas that customers perceive most frequently, and its appearance gap is an important part of the appearance quality of the entire vehicle.

[0003] In the prior art, the assembly and positioning methods of the hidden external opening handles on the side doors of automobiles are mainly divided into two methods: self-positioning of parts and tooling positioning. Self-positioning of parts requires extremely high precision in the stamping and welding of sheet metal for doors, and the assembly process requires the external opening handle to be pushed in one direction to achieve positioning and assembly. Tooling positioning is currently mainly achieved through the tooling of handle jackets, which are divided into two categories: recyclable tooling and disposable positioning sheaths. The former has the risk of damaging the paint of the external opening handle during the assembly process, and the latter will increase the cost of parts.

[0004] For example: CN207027350U discloses a positioning tool for installing a flat door handle, including a main body, an inner fitting surface arranged on one side of the main body, the inner fitting surface is used to fit on the outer surface of the handle when installing the handle, and an outer fitting surface surrounding the inner fitting surface, the outer fitting surface is used to fit on the outer surface of the door when installing the handle; a gap plug ring is also arranged between the inner fitting surface and the outer fitting surface, the gap plug ring is used to limit the gap of the handle to be installed on the outer circumference relative to the door hole. The gap plug ring is in the form of an annular sleeve as a whole, and is made by injection molding. The gap plug ring in the form of an annular sleeve needs to go through several rounds of mold repair before it can be solidified to fit the size, which takes a long period of time, and it is difficult to apply when the gap changes, and the versatility is also poor.

[0031] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. The drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0032] In one embodiment, see Figure 1 As shown, a hidden door outer handle assembly tool is provided, including a base 1, the inner side surface of the base 1 is provided with a first positioning portion 11 that is adapted to the outer surface of the door outer panel 2, the middle portion of the base 2 is provided with a second positioning portion 12 that protrudes from the inner side surface of the base and is adapted to the inner wall of the mounting hole 21 on the door outer panel 2, and the middle portion of the base 1 is provided with a third positioning portion 13 that protrudes from the inner side surface of the base and is adapted to the positioning hole 31 on the hidden door outer handle base 3.

[0033] In this arrangement, the first positioning portion 11 provided on the inner side surface of the base 1 is matched with the outer surface of the door outer panel 2 to achieve the Y-direction positioning of the base 1, and the second positioning portion 12 protruding from the inner side surface of the middle part of the base 1 is matched with the inner wall of the mounting hole 21 on the door outer panel 2 to achieve the X-direction and Z-direction positioning of the base 1. The coordinated positioning of the first positioning portion 11 and the second positioning portion 12 ensures the relative position accuracy between the base 1 and the door outer panel 2. Furthermore, the third positioning portion 13 protruding from the inner side surface of the middle part of the base 1 is matched with the positioning hole 31 on the hidden door outer handle base 3 to achieve the X-direction and Z-direction positioning of the hidden door outer handle base 3, thereby ensuring the relative position accuracy between the hidden door outer handle base 3 and the door outer panel 2.

[0034] See also Figures 3 to 5 As shown, the hidden door outer handle assembly includes a hidden door outer handle base 3 and an outer end cover 5 fixed on the hidden door outer handle base 3, and the outer end cover 5 is gap-matched with the inner wall of the mounting hole 21 on the door outer panel 2.

[0035] When the assembly tool is used specifically, refer to Figures 6 to 8 As shown, first disassemble the outer end cover 5 of the hidden door outer handle assembly, then fit the first positioning portion 11 of the base 1 of the assembly tool to the outer surface of the door outer panel 2, and align the second positioning portion 12 of the base 1 to insert into the mounting hole 21 of the door outer panel 2. Then align the positioning hole 31 of the hidden door outer handle base 3 with the third positioning portion 13 of the base 1, keep the base 1 immobile, push the hidden door outer handle base 3 to make it fit with the inner surface of the door outer panel 2, tighten the fastening member 33 on the hidden door outer handle base 3, and fix the hidden door outer handle base 3 on the inner surface of the door outer panel 2. Finally, pull the base 1 outward to disengage the third positioning portion 13 from the positioning hole 31 and the second positioning portion 12 from the mounting hole 21. After the base 1 is disassembled, the outer end cover 5 of the hidden door outer handle assembly is inserted from the mounting hole 21 of the door outer panel 2 and fixed to the hidden door outer handle base 3 to complete the assembly of the hidden door outer handle assembly.

[0036] The overall structure of the assembly tool is simple. When in use, the outer end cover 5 of the hidden vehicle door outer opening handle assembly is disassembled, and the assembly tool is used to replace the outer end cover 5 for positioning and adjustment. Finally, the assembly tool is removed and the outer end cover 5 is restored to its original position. In this way, it is ensured that the outer surface of the outer end cover 5 and the outer surface of the vehicle door outer panel 2 are in the same plane or the same curvature, so that the surface difference between the outer surface of the outer end cover 5 and the outer surface of the vehicle door outer panel 2 meets the assembly requirements, which not only ensures the assembly quality, but also effectively avoids the problem of paint damage during the assembly process.

[0037] In a preferred embodiment, see Figure 1 , Figure 7 and Figure 8 As shown, the first positioning portion 11 is the edge area of ​​the inner side of the base 1, which fully utilizes the space of the base 1 itself. The first positioning portion 11 corresponds to the outer surface of the door outer panel 2 to achieve Y-axis positioning of the base 1.

[0038] In a preferred embodiment, see Figure 1 As shown, the base 1 is provided with a through hole 14 in the middle thereof, which passes through the inner and outer sides of the base 1. A beam 15 is connected between two opposite side walls of the through hole 14. The second positioning portion 12 and the third positioning portion 13 are fixed on the beam 15. On the one hand, the through hole 14 can reduce the weight of the tooling and facilitate operation; see Figure 2 As shown, on the other hand, the through hole 14 can be used as a visual observation window to observe the coordination between the second positioning portion 12 and the mounting hole 21 of the vehicle door outer panel 2 and the positioning between the third positioning portion 13 and the positioning hole 31 of the hidden vehicle door outer opening handle base 3, so as to better adjust the position of the tooling or the hidden vehicle door outer opening handle base 3 according to the positioning conditions.

[0039] In a preferred embodiment, see Figure 1 As shown, the second positioning portion 12 is a pipe fixed on the beam body 15 and having a closed ring cross-section. One end of the pipe protrudes from the inner side of the base 1 and fits with the inner wall of the mounting hole 21 on the door outer panel to achieve X-direction and Z-direction positioning of the base 1.

[0040] In a preferred embodiment, see Figure 1 As shown, the third positioning portion 13 is a columnar member fixed to the middle of the beam body 15, and the X-direction and Z-direction positioning of the hidden door outside opening handle base 3 is achieved through the corresponding cooperation between the columnar member and the positioning hole 31 on the hidden door outside opening handle base 3.

[0041] In a preferred embodiment, see Figure 1 As shown, there are two beam bodies 15, and the two beam bodies 15 are connected between the upper and lower side walls of the through hole 14 and the two beam bodies 15 are spaced apart. The arrangement of the beam body 15, on the one hand, provides an installation position for fixing the second positioning portion 12 and the third positioning portion 13, thereby realizing the hollowing out of the middle of the base 1, which is convenient for reducing the overall weight of the assembly tool; on the other hand, by arranging the third positioning portion 13 in the middle of the beam body 15 and the two beam bodies 15 are spaced apart, the third positioning portions 13 on the two beam bodies 15 can cooperate with each other, better restricting the X-direction and Z-direction degrees of freedom of the hidden door outer handle base 3, and playing the role of restricting the X-direction and Z-direction of the hidden door outer handle base 3.

[0042] In a preferred embodiment, see Figure 7 and Figure 8 As shown, the third positioning portion 13 is fixedly engaged with the positioning hole 31 on the hidden door outer handle base 3. By adopting the fixing method of the fixing method, the assembly tool can be pre-connected with the hidden door outer handle base 3. After the hidden door outer handle base 3 is fixedly connected with the door outer panel 2, the third positioning portion 13 can be driven by external force to be separated from the positioning hole 31 of the locking fit, so that the assembly and disassembly are convenient and quick, and easy to implement.

[0043] In a preferred embodiment, the base 1 is a wear-resistant part made by subtractive processing or an wear-resistant part made by additive processing. Exemplarily, the material of the base 1 is steel or nylon.

[0044] Among them, subtractive processing (such as turning, milling, grinding, etc.) is a processing method that removes excess parts from raw materials to form the required shape and size. Subtractive processing can ensure the surface finish and accuracy of the parts. Through precise cutting and grinding, possible defects and burrs can be removed, making the surface smoother and reducing friction and wear.

[0045] Additive machining (such as 3D printing, powder metallurgy, etc.) is a machining method that builds a part by adding materials layer by layer. Additive machining provides flexibility and design freedom to manufacture complex shapes and structures to optimize wear resistance. For example, through internal structural design or material gradient changes, a base with different wear resistance in different areas can be achieved1. In addition, additive machining can also achieve material customization and mixing, such as adding wear-resistant particles or fibers to the matrix material to improve the overall wear resistance.

[0046] In a preferred embodiment, see Figure 3 , Figure 5 and Figure 8 As shown, the concealed door handle base 3 is provided with a plurality of positioning bosses 32 matched with the inner surface of the door outer panel 2 near the mounting hole 21 , and the positioning bosses 32 are used to realize the Y-direction positioning of the concealed door handle base 3 .

[0047] In a preferred embodiment, see Figure 1 As shown, a handle 4 is fixed to the base 1. The handle 4 is a component designed to be held or grasped. It is usually used to provide a means for convenient operation or movement of the device.

[0048] It should be noted that the handle 4 can have a variety of shapes and sizes to suit different gripping needs and ergonomic requirements. For example, the handle 4 on a mechanical device may be made of a solid material and have a non-slip surface to ensure that the operator can hold it firmly when operating the machine. The handle 4 should also have a comfortable shape and a design that is easy to hold.

[0049] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or modification made by a person skilled in the art based on the present invention is within the protection scope of the present invention.
