Description

Technical Field

[0001] This invention relates to the field of vehicle body structure technology, and in particular to a door and exterior handle mounting structure. Background Technology

[0002] There are two main ways to install the exterior door handles of heavy-duty trucks: one is to pre-embed nuts in the base of the exterior door handle, design mounting holes on the outer door panel and the reinforcing plate, and open mounting holes in the inner door panel at the corresponding positions of the pre-embedded nuts. Power tools are then passed through the mounting holes to fix the exterior door handle. Although this method of installing the exterior door handle is simple, the mounting holes on the inner door panel cannot be blocked by the inner door panel and need to be sealed with plugs or sealants. After long-term use, there is a risk of the handle falling off or not sealing properly, which affects the door's sealing performance and the vehicle's quality. Another method is an assembly method that combines snap-fit ​​and screws. First, the outer door handle base slot is snapped into the welding edge of the groove hole on the outer door panel. Then, the pre-embedded nut of the handle base is aligned with the mounting hole of the outer door panel reinforcement plate. Since the mounting hole of the reinforcement plate is lower than the opening of the inner door panel, and there is no opening in the inner door panel corresponding to these two holes, it can only be assembled with special tools. The assembly process is time-consuming and labor-intensive. Once damaged, the inner door panel, waterproof membrane and other parts need to be removed for repair and replacement. Some models also need to remove the window regulator. Repair and replacement are not only costly but also complicated.

[0003] For the first scenario: there is a risk that the installation holes for the external handle and the door may be exposed, and there is a risk that the plug or sealant may fall off or not seal properly. For the second scenario: the external handle of the door is difficult to assemble, the repair and replacement process is complicated, and the repair cost is high. Summary of the Invention

A pre-embedded nut is provided behind the outer handle base to fit against the door inner panel. The outer handle is fixed to the door inner panel by seven slots and one pre-embedded nut.

[0007] Preferably, the outer door panel is designed with a groove hole that matches the shape of the outer handle. The groove hole has a groove welding edge, and the groove welding edge has a notch that corresponds to the outer handle slot. The size of the notch is larger than the size of the slot. The groove hole welding edge is partially extended and has three partial extension structures that are spot welded to the reinforcing plate.

[0008] Preferably, the slot is composed of front and rear side plates, a connecting plate and a base plate; one side of the base plate is connected to the outer handle base, and the other side of the base plate is provided with a connecting plate with one end protruding outward, the top of the connecting plate being 5mm higher than the upper surface of the base plate; the front and rear sides of the connecting plate are provided with front and rear side plates, and the front and rear side plates are provided with a groove in the middle; the slot and the outer handle base form a U-shaped structure.

Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0021] The door and outer handle mounting structure of the present invention includes an outer handle 1, an outer door panel 2, an inner door panel 3, and a reinforcing plate 4; as shown... Figure 1 As shown, the exterior door handle 1 is fixed to the interior door panel 3 via seven slots 5 and one pre-embedded nut 10. Three slots 5 are designed above the base of the exterior door handle 1, and four slots 5 are designed below the base of the exterior door handle 2. Figure 2 As shown, the pre-embedded nut 10 is located behind the base of the outer door handle 1 and fits against the inner door panel 3, serving as a front-to-back positioning element. In this invention, four slots are designed from front to back below the base of the outer door handle, and three slots are designed from front to back above the base of the outer door handle.

[0022] like Figure 3 As shown, the outer panel 2 of the car door is provided with a groove hole 6 that matches the shape of the outer handle. The groove hole 6 has a groove welding edge 7 on its outer periphery. The groove welding edge 7 is provided with a notch 8 whose position corresponds to the outer handle slot 5. The size of the notch 8 is larger than the size of the slot 5.

[0023] like Figure 4 As shown, three local extension structures 9 are provided on the groove welding edge 7 and spot-welded together with the reinforcing plate 4 to improve the installation strength of the door outer handle.

[0024] When installing the outer handle, first align the slot 5 below the outer handle 1 with the notch 8 on the groove hole 6 of the outer door panel 2, while ensuring the outer handle 1 is flush against the outer door panel 2. Then, move the outer handle 1 towards the rear of the door. During this movement, the slot 5 of the outer handle 1 passes through the notch 8 of the outer door panel 2 and engages with the groove welding edge 7. Continue moving it backward until it can no longer be moved. Figure 5 As shown, observe whether the pre-embedded nut 10 hole of the door handle 1 is aligned with the mounting hole of the inner door panel 3. After confirming that the mounting hole is aligned, use a power tool to fix the M6 ​​screw 11 to the inner door panel 3. This structure can ensure the assembly and maintenance of the door handle with ordinary power tools, which is convenient and simple to operate, while reducing the number of screws and reducing costs.

[0025] like Figure 6 and Figure 7As shown, the slot 5 consists of front and rear side plates 5-1, a connecting plate 5-2, and a base plate 5-3. One side of the base plate 5-3 is connected to the base of the outer handle 1, and the other side of the base plate 5-3 is vertically provided with a connecting plate 5-2 protruding at one end. The top of the connecting plate 5-2 is 5mm higher than the upper surface of the base plate 5-3. The front and rear side plates 5-1 are provided on the front and rear sides of the connecting plate 5-2, and a groove is provided in the middle of the front and rear side plates 5-1. Depending on the snap-fit ​​position, the front and rear side plates 5-1 can be located inside or at the lower end of the connecting plate 5-2. The cross-section of the front and rear side plates 5-1 can be strip-shaped or triangular, that is, the groove can be flat or oblique.

[0026] The slot 5 and the base of the outer handle 1 form a U-shaped structure. The U-shaped structure is snapped into the groove welding edge 7 of the outer door panel 2, thus achieving the snap-fit ​​of the outer handle. The effect after snap-fit ​​is as follows: Figure 8 As shown.

[0027] In this invention, an M6 pre-embedded nut is designed behind the base of the outer handle 1 for assembling an M6 screw. The protrusion of the pre-embedded nut 10 fits against the inner panel 3 of the car door to achieve the positioning and fixing of the outer handle of the car door.

[0028] This invention discloses a door and exterior handle mounting structure. The exterior handle assembly method is simple: First, align the slot below the exterior handle with the notch in the groove of the door's outer panel, ensuring the exterior handle is flush against the outer panel. Then, move the exterior handle towards the rear of the door. During this movement, the slot passes through the notch and engages with the welded edge of the groove, positioning the exterior handle in the Y and Z directions. Continue moving backward until the pre-embedded nut hole mounting surface of the exterior handle aligns with the inner panel of the door, positioning the exterior handle in the X direction. After aligning the mounting holes, secure the exterior handle and the inner panel of the door with screws. This invention allows for exterior handle replacement and repair simply by removing the screws.
