Description

Technical Field

[0001] This utility model relates to the field of vehicle inspection technology, and in particular to a tool for inspecting the water-cutting mounting surfaces inside and outside vehicle doors. Background Technology

[0002] The door sealant on a car is a rubber sealing strip in the recess of the window, located between the window glass and the door frame. The outer sealant is the sealing strip on the outside of the door glass, and the inner sealant is the sealing strip on the inside of the door glass. The door sealant is closely attached to both the inner and outer sides of the door glass.

[0003] The core function of the exterior water deflector is to seal and waterproof, preventing rainwater, car wash water, and other substances from flowing into the car door along the glass. The exterior water deflector has specific channels designed to guide water on the glass to a designated location for drainage, protecting components inside the car such as speakers, window regulators, and wiring harnesses. Both the interior and exterior water deflectors remove water droplets, fog, and dust from the glass surface when the windows are raised or lowered, and also guide and buffer the glass movement. At high speeds, the close fit between the interior and exterior water deflectors and the glass reduces air turbulence and wind noise. Furthermore, the interior and exterior water deflectors also serve as a decorative element, concealing the vehicle's metal structure and making the interior appear more complete and refined.

[0004] The machining precision of the mounting surface (i.e., the metal surface on the door sheet metal used to install the water cutter) is crucial for both internal and external water cutters. Insufficient flatness and contour precision will not only lead to poor sealing, resulting in water and dust leaks and excessive wind noise; it will also cause assembly difficulties, making it hard for workers to install, and causing quality problems such as damage to the clips or gaps and warping after installation; it will also result in uneven surface finish between the installed water cutter and surrounding parts, affecting the aesthetics.

[0005] Traditional inspection methods utilize integrated fixtures, which have several limitations: fixture development takes 2-3 months, requires a large area, and is costly; the inspection process requires moving the vehicle door from the production line to a dedicated inspection area, with each unit taking over 10 minutes to inspect, resulting in low efficiency. During the new vehicle development phase, the lack of integrated fixtures necessitates relying on individual or assembly fixtures for troubleshooting, leading to even lower efficiency and difficulty in responding to and resolving on-site issues promptly. Particularly during the project manufacturing phase, existing technology cannot meet the urgent need for rapid inspection of internal and external water-cutting surfaces.

[0006] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a tool for inspecting the water-cutting surfaces inside and outside car doors that has high detection efficiency, is easy to operate and has low cost.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0009] A tool for inspecting the water-cutting mounting surfaces inside and outside a vehicle door, comprising:

[0010] The measuring ruler has an outer measuring reference surface formed on its outer side and an inner measuring reference surface formed on its inner side. The distance between the outer measuring reference surface and the inner measuring reference surface is constant and less than the width of the inner and outer water-cutting mounting grooves on the car door.

[0011] Positioning components are used to position the measuring ruler within the inner and outer water-cutting mounting grooves.

[0012] A further technical solution is that the front and rear ends of the detection ruler each have a first positioning section, and the width of the first positioning section is the same as the width of the inner and outer water-cutting installation grooves.

[0013] A further technical solution is that the positioning component includes:

[0014] The connectors, located at the front and rear ends of the measuring ruler, can be inserted into the front and rear guide slots of the car door, respectively; and

[0015] A suspension part is provided on the upper surface of the measuring ruler, and the width of the suspension part is greater than the width of the inner and outer water-cutting installation grooves.

[0016] A further technical solution is that the plug-in portion includes:

[0017] A retaining pin is used to fix one end of the measuring ruler; and

[0018] A movable pin is located at the other end of the measuring scale, and the movable pin can extend or retract along the length of the measuring scale.

[0019] A further technical solution is that both the fixed pin and the movable pin include a guide section and a second positioning section;

[0020] The second positioning section is located at the fixed end of the fixed pin and the movable pin, and its width is equal to the width of the inner cavity of the corresponding front guide groove or rear guide groove.

[0021] The guide section is located at the free end of the fixed pin and the movable pin, and its width is smaller than the width of the inner cavity of the corresponding front guide groove or rear guide groove.

[0022] A further technical solution is that the movable pin includes:

[0023] A fixed base, fixed to the measuring scale, is provided with a slide rail extending along the length of the measuring scale, and a sliding hole in the same direction as the slide rail is provided on the side wall of the fixed base; and

[0024] A movable pin is slidably disposed within a slide rail, and a lever perpendicularly disposed thereon is fixed on the movable pin, the lever extending from the slide hole to the outside of the fixed base.

[0025] A further technical solution is that the suspension part has two parts, which are symmetrically arranged front and back with the center line of the length direction of the measuring ruler as the center line.

[0026] A further technical solution is that the two ends of the suspension part extend symmetrically to the inner and outer sides of the measuring ruler.

[0027] A further technical solution is that the measuring ruler is provided with multiple weight reduction zones.

[0028] A further technical solution is that the upper surface of the measuring ruler is provided with a handle.

[0029] The beneficial effects of adopting the above technical solution are as follows:

[0030] Whether the gap width between the outer measuring reference surface on the measuring ruler and the outer mounting surface on the inner and outer water-cutting mounting groove is uniform is the standard for judging whether the outer water-cutting mounting surface is flat; whether the gap width between the inner measuring reference surface on the measuring ruler and the inner mounting surface on the inner and outer water-cutting mounting groove is uniform is the standard for judging whether the inner water-cutting mounting surface is flat.

[0031] By using this door interior and exterior waterstop mounting surface inspection tool, the door can be inspected directly on the production line without having to be moved to a dedicated inspection fixture. Traditional inspection fixtures require complex positioning mechanisms, while this tool achieves self-positioning through the matching of the inspection ruler with the dimensions of the interior and exterior waterstop mounting grooves, significantly simplifying the structure. Inspection of the interior and exterior waterstop mounting surfaces can be completed in a single positioning and installation, improving inspection efficiency. Inspection time is reduced from ten minutes to less than one minute using traditional methods. The tool's manufacturing cost is only one-tenth of that of traditional inspection fixtures, and it is compatible with multiple vehicle models on the same platform. Operators can perform accuracy assessments without professional training, effectively improving troubleshooting efficiency and avoiding quality problems such as water leakage and abnormal noise caused by insufficient accuracy of the interior and exterior waterstop mounting surfaces.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] In the description of this utility model, the terms "front" refers to the direction of the front of the vehicle, "rear" refers to the direction of the rear of the vehicle, "inner" refers to the inner side of the door, and "outer" refers to the outer side of the door. These terms are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] like Figures 1-5 As shown, a portable inspection tool for the water-cutting mounting surface inside and outside a car door is disclosed. This tool can be used directly at the production line and includes an inspection ruler and a positioning component.

[0041] Example 1:

[0042] The outer surface of the measuring ruler 6 faces the outer water-cutting mounting surface, and an outer measuring reference surface is formed on the outer surface of the measuring ruler 6. The inner surface of the measuring ruler 6 faces the inner water-cutting mounting surface, and an inner measuring reference surface is formed on the inner surface of the measuring ruler 6. The distance between the outer measuring reference surface and the inner measuring reference surface is constant and less than the width of the inner and outer water-cutting mounting grooves on the vehicle door. A positioning component is provided on the measuring ruler 6 to position the measuring ruler 6 within the inner and outer water-cutting mounting grooves, restricting the measuring ruler 6 from moving in the inward and outward and forward and backward directions within the inner and outer water-cutting mounting grooves.

[0043] The measuring ruler 6 is a rectangular strip structure, allowing it to be inserted from top to bottom into the inner and outer water-cutting mounting slots. The machining tolerance for the outer and inner measuring reference surfaces of the measuring ruler 6 is ±0.05mm. During operation, the measuring ruler 6 is placed into the inner and outer water-cutting mounting slots of the vehicle door, and is then positioned using a positioning assembly. The positioning assembly constrains the forward and backward, and inward and outward movement of the measuring ruler 6 at both ends. The positioning assembly also constrains the downward movement of the measuring ruler 6, ensuring that the inner and outer measuring reference surfaces remain relatively stable with the inner and outer mounting surfaces of the inner and outer water-cutting mounting slots.

[0044] The uniformity of the gap between the outer reference surface of the measuring ruler 6 and the outer mounting surface of the inner and outer water-cutting grooves is the standard for judging whether the outer water-cutting mounting surface is flat. Similarly, the uniformity of the gap between the inner reference surface of the measuring ruler 6 and the inner mounting surface of the inner and outer water-cutting grooves is the standard for judging whether the inner water-cutting mounting surface is flat. The gap width between the measuring reference surface of the measuring ruler 6 and the corresponding mounting surface of the inner and outer water-cutting grooves is d, where d > 0 mm. The typical design value for d is 3 mm, and it can be determined directly by observation or using auxiliary measuring tools (such as a feeler gauge).

[0045] If there is a flatness or contour deviation on the mounting surface of the inner and outer water-cutting grooves, the gap width between the detection reference surface on the detection ruler 6 and the corresponding mounting surface of the inner and outer water-cutting grooves will change and become a non-constant width value.

[0046] The use of this door interior and exterior waterstop mounting surface inspection tool eliminates the need to transport the door to a dedicated inspection fixture, allowing for direct inspection on the production line. Traditional fixtures require complex positioning mechanisms, while this tool achieves self-positioning through the matching of the inspection ruler 6 with the dimensions of the interior and exterior waterstop mounting grooves, significantly simplifying the structure. A single positioning and installation of the tool completes the inspection of both interior and exterior waterstop mounting surfaces, improving inspection efficiency. Inspection time is reduced from ten minutes to less than one minute using traditional methods. The tool's manufacturing cost is only one-tenth that of traditional fixtures and it is compatible with multiple vehicle models on the same platform. Operators can perform accuracy assessments without specialized training, effectively improving troubleshooting efficiency and preventing quality issues such as leaking seals and abnormal noises caused by insufficient precision of the interior and exterior waterstop mounting surfaces.

[0047] The limitations of fixed installation in traditional inspection tools have prompted a shift in research and development towards mobility, achieving rapid positioning and inspection through structural simplification. Considering the fixed width of the inner and outer water-cutting mounting slots, the gap value formed between the reference surface and the mounting surface is observed or measured instead of complex measurement methods. At the same time, a rapid positioning component is set up to eliminate manual alignment errors, ultimately resulting in an inspection tool that can be adapted to different vehicle door structures.

[0048] Example 2:

[0049] To further limit the movement of the measuring ruler 6 after installation, both the front and rear ends of the measuring ruler 6 have a first positioning section 61. The width of the first positioning section 61 is the same as the width of the inner and outer water-cutting installation grooves, thereby limiting the inner and outer displacement of the measuring ruler 6 within the inner and outer water-cutting installation grooves.

[0050] Example 3:

[0051] In addition, multiple weight-reduction zones can be set on the measuring ruler 6. These zones are grooves or notches on the surface of the measuring ruler 6. These zones are evenly spaced along the length of the measuring ruler 6 and symmetrically arranged front and back with the center line of the measuring ruler 6 as the center. This reduces the weight of the measuring ruler 6 and helps maintain its weight balance, making the measuring ruler 6 more stable after installation.

[0052] Example 4:

[0053] The positioning component includes a plug-in part and a suspension part 1.

[0054] The insertion part is used to position the detection ruler 6 in the inward and outward and front-back directions. The insertion part is located at the front and rear ends of the detection ruler 6 and can be inserted into the front guide groove and rear guide groove of the door respectively. The width of the insertion part must be consistent with the width of the corresponding front guide groove or rear guide groove, thereby limiting the inward and outward displacement of the detection ruler 6.

[0055] The insertion parts are positioning structures located at both ends of the measuring ruler 6. They can be implemented using rigid rods or pins. The insertion parts at both ends are inserted into the front and rear guide grooves of the vehicle door, respectively. By utilizing the interlocking fit between the insertion parts and the front and rear guide grooves on the vehicle body, the measuring ruler 6 is limited both front-to-back and inside-out. The front and rear guide grooves are the parts on the vehicle door used for mounting the glass guide groove sealing strip. Generally, the dimensions of the front and rear guide grooves are the same on different models of the same brand. Therefore, the positioning structure using the front and rear guide grooves in this invention has strong versatility.

[0056] The suspension part 1 is located on the upper surface of the measuring ruler 6. The width of the suspension part 1 is greater than the width of the inner and outer water-cutting installation grooves. The machining tolerance requirement for the lower surface of the suspension part 1 is ±0.05mm.

[0057] The suspension part 1 is a positioning structure set above the measuring ruler 6. Specifically, it can be implemented by a horizontally extending boss or baffle. The suspension part 1 is placed on the top of the inner and outer water-cutting mounting grooves. The top edge of the inner and outer water-cutting mounting grooves supports the suspension part 1, so that the measuring ruler 6 is suspended in the inner and outer water-cutting mounting grooves. With the help of the tool's own weight, the vertical displacement of the measuring ruler 6 in the inner and outer water-cutting mounting grooves is limited.

[0058] The cooperation between the plug and the suspension part 1 also prevents the measuring ruler 6 from skewing inward or outward or shifting forward or backward, ensuring that the positional relationship between the measuring reference surface and the mounting surface remains constant.

[0059] The positioning component achieves rapid positioning of the inspection tool and the car door through the direct engagement of the connector and the limiting effect of the suspension part 1. During the inspection process, there is no need to disassemble the car door or use complex fixtures; the alignment inspection can be completed directly next to the production line. This solves the problems of low inspection efficiency and complex operation of traditional inspection fixtures. Through the synergistic action of the connector and the suspension part 1, the inspection tool can quickly complete the positioning and locking with the car door, shortening the inspection time and meeting the needs of rapid inspection next to the production line.

[0060] Example 5:

[0061] The connector includes a fixed pin 2 and a movable pin 3. The fixed pin 2 is fixed to one end of the measuring scale 6. The fixed pin 2 is a positioning component that is rigidly connected to one end of the measuring scale 6. It can be fixed to the measuring scale 6 by welding or bolting. Its function is to provide a stable reference positioning for that end of the measuring scale 6. The movable pin 3 is located at the other end of the measuring scale 6. The movable pin 3 can extend and retract along the length direction of the measuring scale 6 (i.e., the front-rear direction of the vehicle body). Its function is to adjust the position of the movable pin rod 32 to adapt to the differences in the spacing of the front and rear guide slots of different doors, and to insert the connectors at both ends into the corresponding front and rear guide slots.

[0062] During assembly, first retract the movable pin 3, insert the fixed pin 2 into the corresponding guide groove, then align the movable pin 3 with another guide groove, and adjust the extension of the movable pin 3 into the corresponding guide groove until the length of the movable pin 3 can no longer be extended. After the inspection is completed, retract the movable pin 3 and the tool can be removed.

[0063] Example 6:

[0064] The movable pin 3 may include a fixed base 5 and a movable pin rod 32. The fixed base 5 is fixed to the measuring scale 6. The fixed base 5 is provided with a slide rail opened along the length direction of the measuring scale 6. The side wall of the fixed base 5 is provided with a sliding hole 31 in the same direction as the slide rail. The movable pin rod 32 is slidably disposed in the slide rail. A lever 4 is fixed on the movable pin rod 32 and is arranged perpendicular to it. The lever 4 extends from the sliding hole 31 to the outside of the fixed base 5.

[0065] The fixed base 5 is the basic structure installed on the measuring ruler 6 to support the sliding of the movable pin 32. Specifically, it can be made of metal or high-strength plastic block and machined into a structure with a sliding track. The track matches the sliding trajectory of the movable pin 32 to limit its movement direction. The sliding hole 31 is a strip-shaped through hole formed in the side wall of the fixed base 5, providing displacement space for the lever 4. The movable pin 32 is a positioning component for insertion into the front or rear guide groove. By adjusting the position of the movable pin 32, it can be adapted to door guide grooves with different spacing. The lever 4 is a control component perpendicularly connected to the movable pin 32. Specifically, it can be fixed to the side wall of the movable pin 32 by welding or threaded connection. The operator can move the movable pin 32 along the track by moving the lever 4.

[0066] A certain amount of friction can be provided between the sliding hole 31 and the lever 4, and between the movable pin 32 and the slide rail, to limit the flexibility of the movement of the lever 4 and the movable pin 32, thereby ensuring the stability of the position of the movable pin 32 after adjustment.

[0067] To ensure that the fixed pin 2 and the movable pin 3 are at the same height, the fixed pin 2 can also be provided with a fixed seat 5.

[0068] Example 7:

[0069] Both the fixed pin and the movable pin include a guide section and a second positioning section. The second positioning section is located at the fixed end of the fixed pin and the movable pin, and its width is equal to the width of the inner cavity of the corresponding front guide groove or rear guide groove. The second positioning section is adapted to the front guide groove or rear guide groove to position the measuring ruler.

[0070] The guide section is located at the free end of the fixed pin and the movable pin, and its width is smaller than the width of the inner cavity of the corresponding front guide groove or rear guide groove. The guide section facilitates the fixed pin and the movable pin to enter the corresponding guide groove.

[0071] Example 8:

[0072] The suspension part 1 has two parts, which are symmetrically arranged front and back with the center line of the length direction of the measuring ruler 6 as the center line. By balancing the constraint forces on both sides, the measuring ruler 6 is prevented from tilting or shifting in the mounting groove.

[0073] Both ends of the suspension part 1 extend symmetrically to the inner and outer sides of the measuring ruler 6, forming a physical limit through the width difference. The consistent extension of both ends of the suspension part 1 balances the force on the measuring ruler 6. The symmetrical extension design ensures that the measuring ruler 6 is subjected to uniform force within the mounting groove, avoiding tilting or displacement caused by unilateral force.

[0074] Example 9:

[0075] The upper surface of the measuring ruler 6 is provided with a handle 7. The handle 7 is a component on the upper surface of the measuring ruler 6 for gripping and operation, and can be installed in a fixed or detachable manner. When the measuring ruler 6 is initially fixed in the door mounting slot by the positioning component, the operator can perform fine-tuning and positioning by gripping the handle 7. The handle 7 is located in the middle of the upper surface of the measuring ruler 6, ensuring a uniform distribution of operating torque and maintaining a horizontal position during adjustment, thus improving ease of operation on the assembly line.

[0076] The above are merely preferred embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
