Abstract
Description
Technical Field
[0001] This utility model relates to the automotive manufacturing industry, and in particular to a protective cover for the exterior trim panel of a vehicle tailgate. Background Technology
[0002] As an important part of the vehicle's exterior, the gap between the tailgate area and the side panel is a key indicator of assembly quality. The tolerance usually needs to be controlled within ±1mm to meet consumers' aesthetic needs.
[0003] However, the exterior trim panels are usually assembled in the final assembly workshop, and the body-in-white completed in the welding workshop does not include this part. This leads to a quality control challenge: how to effectively ensure, during the welding stage, that the tailgate sheet metal to which the future final assembly exterior trim panels are attached, and the clearance dimensions between it and its surrounding parts (mainly the side panels) meet the requirements.
[0004] Traditional inspection methods use gap gauges or calipers, but these are often ineffective for direct and accurate measurements in areas with complex shapes, such as rounded transitions or large gaps. Existing inspection fixtures may suffer from drawbacks such as complex design, bulkiness, and inconvenience in operation. These not only increase the workload of operators and affect production efficiency at high speeds, but can also lead to batch-level dimensional deviations flowing into subsequent processes, causing significant quality losses. Utility Model Content
[0005] The purpose of this invention is to provide a protective cover for the exterior trim panel of a vehicle tailgate to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a tailgate exterior trim panel protector, comprising: a connecting block, a support, a gasket assembly, and at least one positioning pin; The support is fixed to one side of the connecting block by fasteners; The gasket assembly is disposed between the fixed mating surfaces of the support and the connecting block, and is used to adjust the position of the support relative to the connecting block in the left-right direction; At least one positioning pin is fixedly installed on the connecting block to cooperate with the positioning hole on the tailgate sheet metal to realize the positioning and installation of the guard on the tailgate and to make the detection surface of the guard fit against the outer panel of the tailgate.
[0007] Preferably, the gasket group is composed of multiple gaskets of different thicknesses.
[0008] Preferably, the total adjustment gap of the gasket group is 5mm.
[0009] Preferably, the gasket set includes gaskets with thicknesses of 2 mm, 2 mm, 0.5 mm and 0.5 mm.
[0010] Preferably, the number of positioning pins is three, namely a first positioning pin, a second positioning pin, and a third positioning pin.
[0011] Preferably, the positioning pin is a pin with a positioning surface.
[0012] Preferably, the fastener is a bolt.
[0013] Preferably, it also includes a handle, which is disposed on the connecting block.
[0014] Preferably, the guard is a pair arranged symmetrically on the left and right sides, respectively used to detect the gap between the left and right sides of the tailgate and the side panel.
[0015] The technical effects and advantages of this utility model are as follows: By using a set of shims between the support and the connecting block, the overall dimensions of the protective body can be finely adjusted to compensate for manufacturing tolerances or adapt to minor changes in different vehicle models, enhancing the versatility and long-term reliability of the tooling. Precise engagement between at least one locating pin and the locating hole on the tailgate sheet metal ensures the uniqueness and repeatability of the protective body's installation position each time. The dimensions of the protective body's inspection surface are designed and manufactured strictly according to the refined process requirements of the final assembly exterior parts, realistically simulating the assembly state of the exterior parts. Employees can directly judge whether the vehicle body dimensions are qualified by observing the gap between the protective body's inspection surface and the "beak" at the side panel, thereby effectively controlling the accuracy requirements of the gap between the tailgate trim and the left and right sides of the side panel, preventing batch quality problems from the source.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] This invention provides, for example Figures 1-3The tailgate exterior panel of the vehicle shown includes: a connecting block 3, a support 1, a gasket group 2, and at least one positioning pin; Support 1 is fixed to one side of connecting block 3 by fasteners; The gasket group 2 is disposed between the fixed mating surfaces of the support 1 and the connecting block 3, and is used to adjust the position of the support 1 relative to the connecting block 3 in the left and right directions; At least one positioning pin is fixedly installed on the connecting block 3 to cooperate with the positioning hole on the tailgate sheet metal to realize the positioning installation of the guard on the tailgate and to make the detection surface of the guard fit with the outer panel of the tailgate.
[0020] By using the shim group 2 positioned between the support 1 and the connecting block 3, the overall dimensions of the protective body can be finely adjusted to compensate for manufacturing tolerances or adapt to minor changes in different vehicle models. This enhances the versatility and long-term reliability of the tooling. Precise engagement between at least one locating pin and the locating hole on the tailgate sheet metal ensures the uniqueness and repeatability of the protective body's installation position each time. The dimensions of the protective body's inspection surface are designed and manufactured strictly according to the refined process requirements of the final assembly exterior parts, realistically simulating the assembly state of the exterior parts. Employees can directly judge whether the vehicle body dimensions are qualified by observing the gap between the protective body's inspection surface and the "beak" area of the side panel, effectively controlling the precision requirements of the gap between the tailgate trim and the left and right sides of the side panel, thus preventing batch quality problems from the outset.
[0021] Furthermore, gasket group 2 is composed of multiple gaskets of different thicknesses.
[0022] Furthermore, the total adjustment clearance of shim group 2 is 5mm.
[0023] Furthermore, the gasket group 2 includes gaskets with thicknesses of 2 mm, 2 mm, 0.5 mm and 0.5 mm.
[0024] Furthermore, there are three positioning pins: the first positioning pin 4, the second positioning pin 5, and the third positioning pin 6.
[0025] Furthermore, the locating pin is a pin with a locating surface.
[0026] Furthermore, the fastener is a bolt.
[0027] Furthermore, it also includes a handle 7, which is mounted on the connecting block 3.
[0028] The protective structure features a simple and lightweight design, and is equipped with a handle 7, greatly facilitating hand operation for workers. Its operation is integrated into the assembly process, eliminating the need for additional complex measurements, significantly reducing the difficulty and intensity of operation for workers, allowing it to easily adapt to a high-paced production rhythm and improving production efficiency.
[0029] Furthermore, the guard is a pair arranged symmetrically on the left and right sides, respectively used to detect the gap between the left and right sides of the tailgate and the side panel.
[0030] Working principle: The operator holds the handle 7 of the protective cover, aligns at least one positioning pin on the protective cover with the corresponding positioning hole on the tailgate sheet metal, and inserts it until the detection surface of the protective cover is completely flush with the outer panel of the tailgate. The design of multiple positioning pins with positioning surfaces ensures the stability and accuracy of the installation, preventing shaking and tilting.
[0031] After the protective shield is installed in place, the outline formed by the connecting block 3 and the support 1 simulates the assembly state of the exterior trim. At this time, workers can visually inspect or use a feeler gauge to measure the gap between the protective shield inspection surface and a specific part of the vehicle body side panel. The accuracy of this gap measurement reference can be ensured by pre-adjusting the shim set 2.
[0032] If the gap value does not meet the requirements, it indicates that there is a deviation in the relative position between the tailgate sheet metal and the side panel, and the tailgate posture needs to be adjusted or the fixture positioning needs to be checked. If the gap value is acceptable, the worker uses a torque gun to tighten the hinge nut at the top of the tailgate to secure the tailgate in its current position.
[0033] After the fastening work is completed, the worker removes the protective device from the tailgate, thus completing one work cycle. The protective device is designed to be simple and lightweight, easy to remove and place, and will not affect subsequent operations.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
