Description

Technical Field

[0001] This utility model relates to the field of automotive interior technology, specifically to a door inspection structure and an automobile. Background Technology

[0002] Currently, the lower door panel and the door sheet metal in car door structures are generally fixedly connected by D-type clips. Specifically, a bracket is set on the B side of the lower door panel, and a locking hole is set on the door sheet metal to engage with the D-type clip. During fixing, the tail end of the D-type clip is inserted into the bracket on the lower door panel, so that the D-type clip is first connected to the lower door panel. Then, the lower door panel is pressed and installed onto the door sheet metal. During the pressing and installation process, the head end of the D-type clip automatically inserts into the locking hole on the door sheet metal. The lower door panel and the door sheet metal are successfully fixedly connected by the D-type clip. After connection, the D-type clip is located between the lower door panel and the door sheet metal. The D-type clip and other connecting parts are not visible from the A side of the lower door panel, ensuring that the A side of the lower door panel is clean and has a good appearance.

[0003] Although the existing D-type clips can stably connect the lower door panel to the door sheet metal and ensure a good appearance, in practical applications, for various reasons, such as repairing parts between the lower door panel and the door sheet metal, it is necessary to open the lower door panel. Since the D-type clips are not exposed between the lower door panel and the door sheet metal, and the outer contour of the lower door panel is not in contact with the door sheet metal, to open the lower door panel, a tool must be inserted into the contact position between the outer contour of the lower door panel and the door sheet metal, and then the lower door panel must be pried open to apply a pull-out force to the D-type clips, eventually causing the D-type clips to disengage from the clips on the door sheet metal, thus completing the removal of the lower door panel. While this method allows for the removal of the lower door panel, the process of using external tools during inspection and disassembly requires inserting a pry tool between the unattached lower door panel and the door sheet metal, and then forcefully prying the lower door panel to remove the D-shaped clips. Inserting the pry tool is very laborious and inconvenient, and the insertion and prying process can easily damage other components inside the door. Therefore, it is necessary to improve the structure of the lower door panel to enhance the convenience of door inspection and maintenance and reduce damage to internal door components. Utility Model Content

[0004] The present invention aims to provide a door inspection structure and automobile to solve the problems of inconvenience and easy damage to the internal parts of the door when disassembling and assembling the lower door panel for inspection and maintenance in the prior art.

[0005] To solve the above problems, the present invention adopts the following technical solution: a car door inspection structure, including a car door sheet metal and a car door lower guard plate connected to each other, the B side of the car door lower guard plate is provided with a plurality of slots arranged along the outline of the outer frame of the car door lower guard plate, the outer frame of the car door lower guard plate is provided with a plug-in disassembly part, and the plug-in disassembly part and the car door sheet metal form a disassembly space for disassembling the car door lower guard plate.

[0006] The principle and beneficial effects of this solution are as follows: In this application, multiple card holders are arranged along the outline of the outer frame of the lower door panel. D-type buckles in the prior art are connected to the card holders, and then the D-type buckles are engaged and fixed with the card holes provided on the sheet metal body. This can form a stable connection between the lower door panel and the door sheet metal. Moreover, the card holders are located at the edge of the outer frame of the lower door panel. After the lower door panel is fixed to the door sheet metal, the connection between the outer frame of the lower door panel and the door sheet metal is tight, and gaps are not easy to occur during use, ensuring a good appearance after the lower door panel is connected.

[0007] In this application, a disassembly and insertion part is provided on the outer frame contour of the lower door panel. The disassembly and insertion part and the door sheet metal form a disassembly space for disassembling the lower door panel. When it is necessary to disassemble the lower door panel to repair the internal parts of the door, the prying tool in the prior art can be inserted into the disassembly and insertion part to make the prying tool conveniently and quickly inserted between the lower door panel and the door sheet metal. Then, by applying force, the lower door panel can be easily moved so that the D-type clip near the disassembly and insertion part is pulled out. When the D-type clip is pulled out to the predetermined pull-out force, the D-type clip is pulled out from the door sheet metal. After the D-type clip is pulled out, the lower door panel near the disassembly and insertion part is opened. At this time, the prying tool can be moved to the adjacent clip position and the D-type clip on the adjacent clip position can be pulled out. Finally, the D-type clips on all clips are pulled out to remove the lower door panel.

[0008] Compared to existing technologies that require inserting a prying tool between the door lower guard plate and the door sheet metal when it is in a non-attached state, the technical solution in this application allows for quick insertion and prying of the prying tool due to the presence of the plug-in disassembly part. This effectively reduces the difficulty of disassembling the door lower guard plate and improves disassembly efficiency, while also reducing the risk of damage to internal door components during the disassembly process.

[0009] Preferably, as an improvement, the plug-in disassembly part includes a disassembly slot formed on the lower door panel.

[0010] In this solution, the plug-in disassembly part is set as a groove-shaped disassembly slot, which is convenient to cooperate with the flat prying tools in the prior art. At the same time, the size of the plug-in disassembly part is minimized to preserve the appearance of the lower door panel to the greatest extent.

[0011] Preferably, as an improvement, at least one bracket is located at the bottom of the lower door panel, and the removal slot is positioned opposite one of the brackets located at the bottom of the lower door panel.

[0012] In this design, the removal slot is positioned on a bracket at the bottom of the lower door panel. This placement makes the slot inconspicuous during use, helping to maintain the panel's appearance. Furthermore, the slot is directly opposite the bracket. When a pry tool is inserted, it aligns with the bracket, allowing for easier and less strenuous removal of the D-shaped clips. Compared to placing the slot between two brackets, this design significantly reduces the force applied to the lower door panel during prying. More importantly, the direct alignment of the slot with the bracket provides a fulcrum for applying force when prying the panel, minimizing pressure and making removal easier and more convenient, while also enhancing the panel's protection.

[0013] Preferably, as an improvement, the width of the disassembly slot is greater than or equal to 20 mm, and the depth of the disassembly slot is greater than or equal to 4 mm.

[0014] In this design, the width of the disassembly slot is set to be greater than or equal to 20mm, and the depth of the disassembly slot is greater than or equal to 4mm, to facilitate the insertion of prying tools.

[0015] Preferably, as an improvement, the card holder positioned opposite the disassembly slot is a base, and a structural reinforcement is provided between the base and the lower door panel.

[0016] In this solution, a structural reinforcement is provided between the base and the lower door panel to enhance the structural strength of the base, enabling it to withstand the force of the prying tool when used with the base, thus facilitating the removal of the D-shaped clips on the base.

[0017] Preferably, as an improvement, the structural reinforcement is a reinforcing rib integrally formed between the base and the lower door panel, with the end of the reinforcing rib facing the door sheet metal flush with the bottom wall of the disassembly slot.

[0018] In this design, the structural reinforcement is an integrally formed reinforcing rib between the base and the lower door panel. The reinforcing rib is easy to form and has a significant structural reinforcement effect. At the same time, the end of the reinforcing rib facing the door sheet metal is flush with the bottom wall of the disassembly slot. When using a prying tool to pry open the D-shaped clip by inserting it into the disassembly slot, the tip of the prying tool can easily enter the top of the reinforcing rib that is flush with the bottom wall of the disassembly slot after being inserted along the disassembly slot. Thus, during the prying process, both the reinforcing rib and the disassembly slot can support the prying tool, making it easier to pull out the D-shaped clip at the base position.

[0019] Preferably, as an improvement, the number of reinforcing ribs is multiple, and the multiple reinforcing ribs are evenly spaced along the outer edge contour direction of the lower door panel.

[0020] In this design, multiple reinforcing ribs are installed to further enhance the structural reinforcement of the base. At the same time, the multiple reinforcing ribs can provide more stable support for the prying tool, making the pull-out of the D-type buckle more stable.

[0021] Preferably, as an improvement, the reinforcing rib has a thickened portion at one end near the base.

[0022] During the prying process, the tip of the prying tool exerts a greater force, and this tip primarily contacts the reinforcing rib. In this design, a thickened section is provided at the end of the reinforcing rib near the base, specifically enhancing the structural strength at the connection point between the reinforcing rib and the base. This allows the reinforcing rib to more stably withstand the force exerted by the prying tool, ensuring more stable disassembly.

[0023] An automobile, including the aforementioned door access structure.

[0024] This solution incorporates a door inspection structure on the vehicle, making it very convenient to remove and install the lower door panel on the vehicle body. The removal and installation process will not damage the internal components of the door, making the inspection process more convenient and efficient. Attached Figure Description

[0028] Figure 4 The same as in Embodiment 2 of this utility model Figure 2A magnified view of a portion of point A in the middle. Detailed Implementation

[0029] The following detailed description illustrates the specific implementation method:

[0030] The reference numerals in the accompanying drawings include: 1. Lower door guard plate; 2. Card holder; 201. Base; 3. Removal slot; 4. Reinforcing rib; 5. Thickened part.

[0031] Example 1

[0032] This embodiment is as shown in the attached figure. Figure 1 and Figure 2 As shown: A door inspection structure includes interconnected door sheet metal and a lower door guard plate 1. Figure 1 (The door sheet metal structure is not shown in the image). The B side of the lower door guard plate is provided with multiple brackets 2 arranged along the outline of the outer frame of the lower door guard plate 1. All brackets 2 are set along the edge of the lower door guard plate 1. At the same time, each bracket 2 is fitted with a D-type buckle in the prior art. In addition, there are holes on the door sheet metal that cooperate with the D-type buckles. When it is necessary to fix the lower door guard plate 1 to the door sheet metal, simply press the head end of the D-type buckle into the hole to fix the D-type buckle to the door sheet metal. Relying on the connection between the multiple D-type buckles and the door sheet metal, a tight fixed connection relationship is formed between the lower door guard plate 1 and the door sheet metal.

[0033] Combination Figure 2 and Figure 3 The outer frame of the lower door panel 1 is provided with a disassembly / removal part, which forms a disassembly space between the disassembly / removal part and the door sheet metal for disassembling the lower door panel 1. Specifically, the disassembly / removal part is a disassembly slot 3 integrally formed on the lower door panel 1. The disassembly slot 3 is located at the edge of the lower door panel 1 and extends through the lower door panel 1. The width of the disassembly slot 3 is greater than or equal to 20mm and the depth is greater than or equal to 4mm. In this embodiment, the width D of the disassembly slot 3 is 22mm and the depth H is 5mm, so that the flat prying tool in the prior art can be smoothly inserted into the disassembly slot 3.

[0034] At the same time, combined Figure 1 and Figure 3At least one of the aforementioned brackets 2 is provided at the bottom of the lower door panel 1, and the disassembly slot 3 is directly opposite one of the brackets 2 located at the bottom of the lower door panel 1. The bracket 2 directly opposite the disassembly slot 3 is a base 201. According to the above description, the width of the disassembly slot 3 is 22mm, and the width of the base 201 is less than the width of the disassembly slot 3. Meanwhile, in this embodiment, a structural reinforcement is provided between the base 201 and the lower door panel 1. The structural reinforcement is a reinforcing rib 4 integrally formed between the base 201 and the lower door panel 1. There are multiple reinforcing ribs 4, which are evenly spaced along the outer edge contour of the lower door panel 1. The end of the reinforcing rib 4 facing the door sheet metal (i.e.,...) Figure 3 The top of the reinforcing rib 4 is flush with the bottom wall of the disassembly slot 3, while the top surface of the base 201 is higher than the top of the reinforcing rib 4, so that a step is formed between the top of the base 201, the top of the reinforcing rib 4, and the plane where the bottom wall of the disassembly slot 3 is located.

[0035] In practical application, under normal use, the lower door guard plate 1 is fixedly connected to the door sheet metal by multiple D-shaped clips. When the lower door guard plate 1 needs to be disassembled for maintenance of the internal parts of the door, simply insert the front end of the flat prying tool into the disassembly hole. Stop inserting when the front end of the prying tool contacts the side wall of the base 201. Then, manually pry the door sheet metal. The front end of the prying tool contacts the reinforcing rib 4 and the bottom wall of the disassembly slot 3. The side wall of the prying tool applies force to the door sheet metal, and the D-shaped clips at the base 201 are pulled out and automatically disengage from the door sheet metal.

[0036] Once the D-shaped clip at the base 201 is detached from the door sheet metal, the portion of the lower door guard plate 1 surrounding the base 201 can be easily separated from the door sheet metal. Then, prying tools can be easily inserted into the gap between the lower door guard plate 1 and the door sheet metal to pull out the D-shaped clips on the remaining clip 2 from the clip holes on the door sheet metal, and finally, the lower door guard plate 1 can be easily removed from the door sheet metal.

[0037] An automobile includes the aforementioned door inspection structure. By installing the door inspection structure inside the door, when it is necessary to remove the lower door panel 1 for inspection of internal door components, a prying tool can be conveniently and quickly inserted between the lower door panel 1 and the door sheet metal through the provided removal slot 3, thereby quickly completing the removal of the lower door panel 1. During the removal process, the main force of the prying tool is located on the bottom wall of the removal slot 3 and the reinforcing rib 4, which will not damage the lower door panel 1 body. At the same time, the base 201 can also provide a certain degree of obstruction to the front end of the prying tool, preventing the prying tool from being inserted into the door and damaging the internal components, thus reducing the damage that may be caused during the door inspection process.

[0038] Example 2

[0039] The difference between Example 2 and Example 1 is as follows: Figure 4 As shown, in this embodiment, a thickened portion 5 is integrally formed at one end of the reinforcing rib 4 near the base 201. The thickened portion 5 is arranged on both sides of the reinforcing rib 4 along the length direction of the reinforcing rib 4. The thickened portion 5 is used to strengthen the structure at the connection position between the reinforcing rib 4 and the base 201. As a result, when the prying tool is used to pry and pull out the D-shaped buckle on the base 201, the reinforcing rib 4 can more stably withstand the force of the prying tool, making the disassembly process more stable.
