Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and specifically relates to a buffer block, an automotive opening and closing component, and an automotive. Background Technology

[0002] Opening and closing components are movable parts in a vehicle body that can be opened or closed, including doors, hoods, and trunk lids. Elastic sealing strips and buffer blocks are used between these components and the vehicle body to absorb the impact force when the components close, reducing vibration and noise caused by direct metal-to-metal collisions. When the components close, the buffer blocks prevent rigid metal-to-metal collisions. Properly placed buffer blocks can also prevent wind noise or aesthetic defects caused by uneven gaps. Furthermore, buffer blocks prevent noise caused by friction between the components and the vehicle body. The screw-in height of the buffer block relative to the opening and closing component directly affects its damping and vibration reduction performance.

[0003] Most existing buffer blocks are designed with a spiral structure, requiring workers to rotate them to the appropriate position during installation. However, this operation demands a high level of dexterity from the worker, often requiring repeated adjustments to ensure proper installation, increasing labor time and resulting in poor assembly efficiency. To address this, existing technologies use markings on the buffer blocks to assist workers in positioning and installation. The screw-in height of the buffer block is determined by aligning the markings with the markings on the opening and closing components. However, currently available buffer blocks only have one type of marking, thus only compatible with one type of vehicle model. When multiple vehicle models are produced on the production line, the screw-in height of the buffer block relative to the opening and closing components varies between models. A single-mark buffer block cannot adapt to multiple models, requiring different models of buffer blocks for different vehicle types. This leads to high parts manufacturing and management costs, time-consuming buffer block replacement, and poor buffer block versatility. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing buffer blocks with only one scale that cannot be adapted to multiple vehicle models, requiring different models of buffer blocks to match different vehicle models, resulting in high parts manufacturing and management costs, time-consuming replacement of buffer blocks, and poor versatility of buffer blocks.

[0005] To solve the above-mentioned technical problems, the present invention discloses a buffer block for installation on an automotive opening and closing component. The automotive opening and closing component has a mounting hole and a marking part. The buffer block includes a mounting part and an operating part arranged sequentially along its length. An external thread is formed on the outer peripheral surface of the mounting part so that the mounting part can be fixedly connected to the mounting hole of the automotive opening and closing component through the external thread. The outer peripheral surface of the operating part is provided with multiple main positioning scales that match different models of automotive opening and closing components. The multiple main positioning scales are evenly spaced around the circumference of the operating part, and each main positioning scale has a different shape. The main positioning scales are used to align with the marking part during the process of the mounting part of the buffer block being screwed into the mounting hole of the automotive opening and closing component.

[0006] Using the above technical solution, the mounting holes on the automotive opening and closing components and the mounting portion of the buffer block are installed via external threads, and the marking portion provides a positioning reference for the buffer block during installation. Multiple main positioning scales on the buffer block are pre-designed according to the requirements of different automotive opening and closing component models, with each main positioning scale corresponding to the screw-in depth standard for a specific model. When assembling an automotive opening and closing component of a certain model, simply locate the specific main positioning scale corresponding to that model for installation. During installation, when the main positioning scale is aligned with the marking portion of the opening and closing component, the screw-in depth of the buffer block precisely meets the buffering requirements of that model of automotive opening and closing component.

[0007] Therefore, the above technical solution integrates multiple main positioning scales into a single buffer block, making it adaptable to various types of automotive opening and closing components (such as doors, hoods, trunk lids, etc.). This eliminates the need for separately designing and manufacturing dedicated buffer blocks for different models of opening and closing components, reducing the types of parts and the number of molds, thus lowering manufacturing costs. Simultaneously, parts management eliminates the need to distinguish between different models, simplifying warehousing, procurement, and assembly processes, further reducing management costs. During assembly, the same buffer block can be aligned with the markings of different models of opening and closing components using different main positioning scales. Assembly of different models of opening and closing components can be completed without changing the buffer block, reducing part changeover time and improving the flexibility and efficiency of the production line. Addressing the differences in installation depth and clearance requirements among different models of opening and closing components, the alignment of different main positioning scales with the markings allows for precise control of the buffer block's screw-in depth, ensuring stable buffering performance in different models of opening and closing components and enhancing the buffer block's versatility.

[0008] According to another specific embodiment of the present invention, a buffer block is disclosed, wherein multiple fine-tuning scales are provided on the outer peripheral surface of the operating part, the multiple fine-tuning scales are evenly spaced around the circumference of the operating part, and the multiple main positioning scales and the multiple fine-tuning scales are staggered around the circumference of the operating part.

[0009] Using the above technical solution, different car models' opening and closing parts (even those from the same series) may have slight differences in gaps or depths due to manufacturing tolerances and assembly errors. Relying solely on the main positioning scale (corresponding to a fixed standard screw-in depth) may not be able to fully match actual needs. The fine-tuning scale can serve as an "intermediate reference" between the main positioning scales, allowing for small-scale adjustments to the screw-in depth after the main positioning scale and the marking section are aligned, ensuring that the buffer block achieves the best buffering effect on different individual vehicles.

[0010] According to another specific embodiment of the present invention, a buffer block is disclosed, wherein the main positioning scale is any one of a protrusion, a groove, a coating, or a scribing line; and the fine adjustment scale is any one of a protrusion, a groove, a coating, or a scribing line.

[0011] Using the above technical solution, the main function of the main positioning scale and the fine adjustment scale is to serve as an indicator to facilitate alignment with the marking part. When the scale is raised or recessed, the alignment between the scale and the marking part can be determined by touch or by observing the position of the scale. When the scale is a coating or engraving, the alignment between the scale and the marking part can be determined by observing the position of the scale.

[0012] According to another specific embodiment of the present invention, a buffer block is disclosed, wherein multiple main positioning scales are set as four main positioning scales, multiple fine adjustment scales are set as four fine adjustment scales, and the four main positioning scales and the four fine adjustment scales are arranged alternately around the circumference of the operating part.

[0013] Using the above technical solution, since the overall volume of the buffer block is small, considering the difficulty of manufacturing the scale on it, the impact of the scale distribution on the recognizability, and the types of car models, setting four main positioning scales and four fine-tuning scales is easy to manufacture, the distribution is moderate and easy to identify, and it can basically adapt to all car opening and closing parts models on the production line.

[0014] According to another specific embodiment of the present invention, a buffer block is disclosed, wherein the four main positioning scales are respectively in the shape of a short teardrop, an equilateral triangle, an inverted triangle and a strip; and each fine adjustment scale is in the shape of a dot.

[0015] Using the above technical solution, the main positioning scale is set with different shapes for easy differentiation. The corresponding main scale shape can be selected and aligned with the marking section according to the different models of automotive opening and closing parts. The fine-tuning scale is set with a dot shape to distinguish it from the main positioning scale.

[0016] The present invention also discloses an automobile opening and closing assembly, including an automobile opening and closing component and a buffer block. The automobile opening and closing component is provided with a mounting hole and a marking part. The mounting part of the buffer block is fixedly installed in the mounting hole. The operating part is located outside the automobile opening and closing component, and the marking part is used to align with a main positioning scale.

[0017] According to another specific embodiment of the present invention, an embodiment of the present invention discloses an automobile opening and closing component. The automobile opening and closing component includes a sheet metal part, and a mounting hole and a marking part are both provided on the sheet metal part. The marking part is configured as a notch located at the outer edge of the mounting hole.

[0018] Using the above technical solution, the notch at the outer edge of the mounting hole can serve as a "guide groove" when the buffer block is inserted into the mounting hole. The external thread of the buffer block can be aligned with the notch, reducing the difficulty of alignment during assembly.

[0019] The present invention also discloses an automobile, including an automobile opening and closing assembly.

[0020] The beneficial effects of this utility model are as follows:

[0021] This utility model provides a buffer block that integrates multiple main positioning scales into a single buffer block, making it adaptable to various models of automotive opening and closing components. This reduces the types of parts and the number of molds, lowering manufacturing costs. It also simplifies warehousing, procurement, and assembly processes, further reducing management costs. During assembly, different models of opening and closing components can be assembled without replacing the buffer block, reducing part changeover time and improving the flexibility and efficiency of the production line. Furthermore, by aligning different main positioning scales with the markings to address differences in installation depth and clearance requirements among different models of opening and closing components, the versatility of the buffer block is enhanced.

[0022] The present invention provides an automotive opening and closing assembly including the buffer block and an automotive opening and closing assembly including the automotive opening and closing assembly. By using the same model of buffer block, the assembly requirements of buffer blocks for different models of automotive opening and closing components in the automotive opening and closing assembly can be met, as well as the assembly requirements of buffer blocks for different models of automotive opening and closing components on the same model of automotive.

[0035] Opening and closing components are movable parts in a vehicle body that can be opened or closed, including doors, hoods, and trunk lids. Elastic sealing strips and buffer blocks are used between these components and the vehicle body to absorb the impact force at the moment of closing, reducing vibration and abnormal noise caused by direct metal-to-metal collisions. The elastic sealing strips fill the gap between the opening / closing component and the body, absorbing impact sound waves, blocking wind and tire noise from entering the vehicle, and preventing rainwater, mud, and dust from entering the cabin. Buffer blocks are installed on the opening / closing component or the door frame. When the opening / closing component is closed to its final stage, the buffer block is compressed, absorbing remaining kinetic energy through elastic deformation, preventing rigid metal-to-metal collisions. Buffer blocks ensure a uniform gap between the opening / closing component and the body after closing, avoiding wind noise or aesthetic defects caused by uneven gaps. Furthermore, during vehicle operation, the opening / closing component may vibrate slightly due to road bumps; the buffer block reduces the amplitude of this vibration through elastic support, preventing abnormal noise caused by friction with the body. The screw-in height of the buffer block relative to the opening / closing component directly affects its damping and vibration reduction performance.

[0036] Most existing buffer blocks are designed with a spiral structure, requiring workers to rotate them to the appropriate position during installation. However, this operation demands a high level of dexterity from the worker, often requiring repeated adjustments to ensure proper installation, increasing labor time and resulting in poor assembly efficiency. To address this, existing technologies use markings on the buffer blocks to assist workers in positioning and installation. The screw-in height of the buffer block is determined by aligning the markings with the markings on the opening and closing components. However, currently available buffer blocks only have one type of marking, thus only compatible with one type of vehicle model. When multiple vehicle models are produced on the production line, the screw-in height of the buffer block relative to the opening and closing components varies between models. A single-mark buffer block cannot adapt to multiple models, requiring different models of buffer blocks for different vehicle types. This leads to high parts manufacturing and management costs, time-consuming buffer block replacement, and poor buffer block versatility.

[0037] To address the aforementioned issues, this utility model provides a buffer block with multiple main positioning scales integrated on it, enabling it to be adapted to various types of automotive opening and closing components. This reduces costs, shortens component changeover time, and improves the versatility of the buffer block.

[0038] To better understand the buffer block, automobile opening and closing assembly, and automobile provided by this utility model, the buffer block will be described in detail below with reference to specific embodiments and accompanying drawings.

[0039] Example 1

[0040] This utility model provides a buffer block 2 for installation on an automotive opening and closing component 1, such as... Figure 1 As shown, the automobile opening and closing component 1 is provided with a mounting hole 11 and a marking part 12. The mounting hole 11 on the automobile opening and closing component 1 and the mounting part 20 of the buffer block 2 can be installed in correspondence through the external thread 201. The marking part 12 provides a positioning reference for the buffer block 2 during installation. The marking part 12 can specifically be a marking line, protrusion, groove, notch, etc. formed near the mounting hole 11.

[0041] It should be noted that the automotive opening and closing component 1 can specifically be a car door, hood, trunk lid, etc. Different models of automotive opening and closing components 1 can be understood as different door models, different hood models, and different trunk lid models for different car models. Alternatively, it can be understood as different door, hood, and trunk lid models for the same car model, due to structural and functional differences. In this embodiment, the opening size of the mounting hole 11 for different models of automotive opening and closing components 1 is uniform, and the diameter (major diameter, minor diameter, and mean diameter) of the internal thread that matches the buffer block 2 is also uniform. Therefore, the diameter of the corresponding buffer block 2 is also uniform. The difference in the installation requirements of the buffer block 2 on different models of automotive opening and closing components 1 lies in the different required height of the buffer block 2 screwed into the mounting hole, that is, the different required lengths of the buffer block 2 outside the mounting hole 11 after installation.

[0042] When the automotive opening / closing component 1 is a door, hood, or trunk lid, the automotive opening / closing component 1 includes a sheet metal part 10. The mounting hole 11 can be a through hole formed on the sheet metal part 10, and the marking part 12 can be a marking line, protrusion, groove, notch, etc. formed on the sheet metal part 10. Specifically, the notch at the outer edge of the mounting hole 11 can be used as the marking part 12. This notch can serve as a "guide groove" when the buffer block 2 is inserted into the mounting hole 11. At the beginning of the installation, the external thread 201 can be aligned with the notch and inserted to avoid the thread getting stuck due to misalignment, thus reducing the difficulty of alignment during assembly. This notch can also serve as a visual reference point to help the assembly personnel quickly identify the screw-in depth of the buffer block 2 by observing whether the scale on the operating part 21 is aligned with the notch.

[0043] Furthermore, such as Figures 1-9 As shown, the buffer block 2 has an overall approximately cylindrical structure, including components along its length ( Figure 1The mounting part 20 and the operating part 21 are arranged sequentially in the direction of the extension of the dashed line. The mounting part 20 is the end that is installed corresponding to the mounting hole 11. The mounting part 20 is cylindrical, and an external thread 201 is formed on the outer circumferential surface of the mounting part 20. The mounting part 20 can be fixedly connected to the mounting hole 11 of the automobile opening and closing part 1 through the external thread 201. It should be noted that the number of turns of the external thread 201 and the pitch of each turn of the external thread 201 are obtained based on actual production experience, and the relevant structural parameters are set to match the existing automobile opening and closing part 1. As the buffer block 2 rotates into the mounting hole 11, the external thread 201 gradually passes through the mounting hole 11. After installation, the external thread 201 may be completely inserted into the mounting hole 11, or a part of the external thread 201 may remain outside the mounting hole 11. By adjusting the length of the external thread 201 inserted into the mounting hole 11 (i.e., the screw-in height), the length of the buffer block 2 outside the mounting hole 11 can be changed, thereby achieving the purpose of adaptively adjusting the gap between the automobile opening and closing part 1 and the vehicle body.

[0044] In one specific embodiment of this utility model, the number of turns of the external thread 201 is set to 3 to 7 turns, such as 3 turns, 4 turns, 5 turns or 6 turns; the pitch of each turn of the external thread 201 is 1mm to 8mm, such as 2mm, 4mm, 6mm or 8mm.

[0045] The operating part 21 is the part held by the installer and also directly contacts the vehicle body, serving as a buffer and energy absorber. The operating part 21 is a frustum of a cone with its diameter gradually decreasing from the direction away from the mounting part 20. Multiple main positioning scales 211, matching different models of automotive opening and closing parts 1, and multiple fine-tuning scales 212 can be formed on the outer circumference of the frustum. The sides of the frustum-shaped operating part 21 are conical, which, compared to flat or angular shapes, better conforms to the curvature of the fingers (especially the fingertips). During operation, the pressure applied by the fingers is evenly distributed on the conical surface, reducing localized pressure and minimizing fatigue during prolonged operation.

[0046] Among them, multiple main positioning scales 211 are evenly spaced around the circumference of the operating part 21. During the process of the mounting part 20 of the buffer block 2 being screwed into the mounting hole 11 of the automobile opening / closing component 1, such as... Figure 1 As shown, buffer block 2 along Figure 1 Rotate the device into the mounting hole 11 in the direction indicated by the dotted line. The main positioning scale 211 is used to align with the marking part 12. See details below. Figure 1 , Figure 7 and Figure 8 The alignment indicated by the arrows in the diagram represents the installation direction of buffer block 2 (refer to...). Figure 1Align the main positioning scale 211 and the marking part 12 on the dotted line in the diagram. Furthermore, the shape of each main positioning scale 211 needs to be set to a different shape so that the main positioning scale 211 can be selected according to the different models of automotive opening and closing parts 1.

[0047] It should be noted that the multiple main positioning scales 211 of the buffer block 2 are pre-designed according to the requirements of different models of automotive opening and closing parts 1. Each main positioning scale 211 corresponds to the screw-in height standard of a certain model of automotive opening and closing part 1. When assembling a certain model of automotive opening and closing part 1, simply find the specific main positioning scale 211 corresponding to that model and install it. During installation, when the main positioning scale 211 is aligned with the marking part 12 of the automotive opening and closing part 1, the screw-in height of the buffer block 2 precisely meets the buffering requirements of that model of automotive opening and closing part 1.

[0048] Therefore, the above technical solution integrates multiple main positioning scales 211 into a single buffer block 2, making it adaptable to various models of automotive opening and closing components 1 (such as car doors, hoods, trunk lids, etc.). This eliminates the need for separately designing and manufacturing dedicated buffer blocks for different models of automotive opening and closing components 1, reducing the types of parts and the number of molds, and lowering manufacturing costs. Simultaneously, parts management eliminates the need to distinguish between different models, simplifying warehousing, procurement, and assembly processes, further reducing management costs. During assembly, the same buffer block 2 can be aligned with the markings 12 of different models of automotive opening and closing components 1 using different main positioning scales 211. Assembly of different models of automotive opening and closing components 1 can be completed without replacing the buffer block 2, reducing part changeover time during assembly and improving the flexibility and efficiency of the production line. Addressing the differences in installation depth and clearance requirements among different models of automotive opening and closing components 1, the alignment of different main positioning scales 211 with the markings 12 allows for precise control of the screw-in depth of the buffer block 2, ensuring that the buffer block 2 provides a stable buffering effect in different models of automotive opening and closing components 1, thus improving the versatility of the buffer block 2.

[0049] Because different models of automotive opening and closing parts 1 may have slight differences in gaps or depths due to manufacturing tolerances, assembly errors, etc., relying solely on the main positioning scale 211 (corresponding to a fixed standard screw-in depth) may not be able to fully match the actual needs. Therefore, in one specific embodiment of this utility model, such as Figure 1 and Figure 9As shown, multiple fine-tuning scales 212 can also be correspondingly set on the outer peripheral surface of the operating part 21. The multiple fine-tuning scales 212 are evenly spaced around the circumference of the operating part 21, and the multiple fine-tuning scales 212 are staggered with the multiple main positioning scales 211 around the circumference of the operating part 21. Preferably, the distance between each fine-tuning scale 212 and the two adjacent main positioning scales 211 is equal. When the corresponding main positioning scale 211 is determined according to the model of a certain car opening and closing part 1, and the main positioning scale 211 is aligned with the marking part 12, the height can be adjusted by a small amount of screwing in the fine-tuning scales 212 on both sides of the main positioning scale 211. As needed, the fine-tuning scale 212 on the left or right side of the main positioning scale 211 can be adjusted to be aligned with the marking part 12. Through small-amplitude precise adjustment, it can be ensured that the buffer block 2 can achieve the best buffering effect on different car opening and closing parts 1. Preferably, each fine adjustment scale 212 has the same shape, but a different shape from the main positioning scale 211, so as to facilitate differentiation.

[0050] In one specific embodiment of this utility model, since the overall volume of the buffer block 2 is small, considering the manufacturing difficulty of the scales on it, the impact of the scale distribution on the recognizability, and the vehicle models, multiple main positioning scales 211 are set as four main positioning scales 211, and multiple fine adjustment scales 212 are set as four fine adjustment scales 212. This setting of the scale distribution has a moderate sparseness, which is convenient for identification and manufacturing, and can basically adapt to all models of automotive opening and closing parts 1 on the production line. Furthermore, the four main positioning scales 211 and the four fine adjustment scales 212 are staggered around the circumference of the operating part 21.

[0051] It should be noted that the number of main positioning scale 211 and fine adjustment scale 212 can also be set to other numbers. For example, the main positioning scale 211 can be set to two, three, five, etc.; the fine adjustment scale 212 can be set to two, three, five, etc., as long as they are evenly spaced on the outer peripheral surface of the operating part 21 to ensure that they can match different models of automotive opening and closing parts 1 and can finely adjust the gap.

[0052] In this embodiment, the preferred configuration is four main positioning scales 211, four fine adjustment scales 212, and a thread pitch of 4mm per turn. The four main positioning scales 211 are spaced 90° apart on the circumference of the operating part 21, and the four fine adjustment scales 212 are also spaced 90° apart on the circumference of the operating part 21. Adjacent main positioning scales 211 and fine adjustment scales 212 are spaced 45° apart. The screw-in height difference between two adjacent main positioning scales 211 is 1mm, and the screw-in height difference between an adjacent main positioning scale 211 and a fine adjustment scale 212 is 0.5mm. See also... Figure 7 and Figure 8 , Figure 7The inverted triangle main positioning scale 211 is aligned with the marking part 12, and the external thread 201 outside the mounting hole 11 has two turns. Figure 8 The inverted triangle main positioning scale 211 is aligned with the marking part 12, and the external thread 201 outside the mounting hole 11 has one turn. That is to say, after rotating the same main positioning scale 211 one turn, the main positioning scale 211 is still aligned with the marking part 12. The corresponding screw-in height difference after one turn is 4mm. With the main positioning scale 211 aligned with the marking part 12, the screw-in height of the buffer block 2 can be intuitively determined by observing the change in the number of turns of the external thread 201.

[0053] In one specific embodiment of this utility model, the main positioning scale 211 is any one of a protrusion, a groove, a coating, or a scribing line; the fine adjustment scale 212 is any one of a protrusion, a groove, a coating, or a scribing line.

[0054] Using the above technical solution, the main function of the main positioning scale 211 and the fine adjustment scale 212 is to serve as a marker so that they can be aligned with the marking part 12. When the scale is raised or recessed, the alignment of the scale with the marking part 12 can be determined by touch or by observing the position of the scale. When the scale is a coating or engraving, the alignment of the scale with the marking part 12 can be determined by observing the position of the scale.

[0055] In one specific embodiment of this utility model, such as Figures 2-6 As shown, the four main positioning scales 211 are each in the shape of a short teardrop (see...). Figure 2 ), equilateral triangle (see Figure 3 ), inverted triangle (see) Figure 4 ) and long strip (see Figure 5 Furthermore, each fine adjustment scale 212 is in the shape of a dot (see...). Figure 6 ).

[0056] Using the above technical solution, the main positioning scale 211 is set with different shapes for easy differentiation. The corresponding main scale shape is selected and aligned with the marking part 12 according to the different models of automotive opening and closing parts 1. The fine-tuning scale 212 is set with a dot shape to distinguish it from the main positioning scale 211. It is understood that the shapes of the main positioning scale 211 and the fine-tuning scale 212 can also be other shapes or numerical markings, as long as they can facilitate differentiation and identification.

[0057] Example 2

[0058] This utility model also provides an automobile opening and closing component, including an automobile opening and closing part 1 and a buffer block 2 of embodiment 1. The automobile opening and closing part 1 is provided with a mounting hole 11 and a marking part 12. When the buffer block 2 is in a state of being assembled and fixedly connected to the mounting hole 11, the mounting part 20 of the buffer block 2 is fixedly installed in the mounting hole 11, the operating part 21 is located outside the automobile opening and closing part 1, and the marking part 12 is used to align with one of the main positioning scales 211 (or fine adjustment scales 212).

[0059] When the opening / closing component 1 is a trunk lid (or door, hood) for different car models, even though they are all trunk lids, the required screw-in height of the buffer block 2 varies due to differences in body shape, size, and cushioning requirements. This means that the amount of compression required for the buffer block 2 when the trunk lid is fully closed differs. Therefore, by using a buffer block 2 with multiple integrated main positioning scales 211, the cushioning requirements of different car models' trunk lids can be adapted. During use, simply determine the corresponding main positioning scale 211 for the trunk lid and adjust it to align with the marking 12 on that model of trunk lid. This ensures a uniform gap between the trunk lid and the car body after closing, preventing rigid collisions between metal parts. Furthermore, using only one type of buffer block 2 reduces the number of parts and molds, lowering costs. During assembly, different models of trunk lids can be assembled without changing the buffer block 2, reducing part changeover time and improving the flexibility and efficiency of the production line. To address the differences in installation depth and gap requirements for different models of trunk lids, the versatility of the buffer block 2 is improved by aligning different main positioning scales 211 with the marking section 12.

[0060] For example, when four car models are produced on the production line, and the trunk lid buffer blocks for these models require four different installation sizes, if conventional buffer blocks are used, four different models of buffer blocks would be needed for matching. However, if the buffer block 2 provided by this invention is used, and if the buffer block 2 is respectively provided with short teardrop-shaped (see...) Figure 2 ), equilateral triangle (see Figure 3 ), inverted triangle (see) Figure 4 ) and long strip (see Figure 5 When there are four types of main positioning scales 211, the four models of trunk lids in the four vehicle types are matched with a main positioning scale 211 of one shape. The corresponding shape of the main positioning scale 211 is selected according to the trunk lid model and aligned with the marking part 12 of the trunk lid for installation.

[0061] When the opening and closing parts 1 of a car are the trunk lid, door, and hood of the same model, the differences in the shape, placement, structure, and function of the trunk lid, door, and hood result in different screw-in heights for the buffer block 2. That is, when the trunk lid, door, and hood are closed to their final stage, the amount of compression required for the buffer block 2 varies. Therefore, by using a buffer block 2 that integrates multiple main positioning scales 211, the buffering requirements of the trunk lid, door, and hood can be adapted. In use, simply determine the corresponding main positioning scale 211 according to the model of the trunk lid, door, and hood, and adjust the main positioning scale 211 to align with the markings 12 on the trunk lid, door, and hood. This ensures a uniform gap between the trunk lid, door, and hood and the car body after closing, preventing rigid collisions between metal parts. Furthermore, using only one type of buffer block 2 reduces the number of parts and molds, lowering costs. During the assembly of different opening and closing parts 1 of the same car model, the assembly operation of buffer blocks 2 for the trunk lid, doors, and hood can be completed without replacing the buffer blocks, reducing part changeover time during assembly and improving the flexibility and efficiency of the production line. To address differences in installation depth and clearance requirements for the trunk lid, doors, and hood, the versatility of buffer blocks 2 is improved by aligning different main positioning scales 211 with the marking section 12.

[0062] For example, when the installation dimensions of the buffer blocks for the trunk lid, front doors, rear doors, and hood of a certain vehicle model are different, if conventional buffer blocks are used, a total of four types of buffer blocks are required for matching. If the buffer block 2 provided by this utility model is used, and the buffer block 2 is respectively provided with short teardrop shapes (see...) Figure 2 ), equilateral triangle (see Figure 3 ), inverted triangle (see) Figure 4 ) and long strip (see Figure 5 When there are four types of main positioning scales 211, the trunk lid, front door, rear door, and hood are each matched with a main positioning scale 211 of a certain shape. For example, the trunk lid corresponds to the short teardrop-shaped main positioning scale 211, the front door corresponds to the equilateral triangle main positioning scale 211, the rear door corresponds to the inverted triangle main positioning scale 211, and the hood corresponds to the long strip-shaped main positioning scale 211. The corresponding shape of the main positioning scale 211 is selected according to the model of these opening and closing parts (trunk lid, front door, rear door, hood) and its marking part 12 is aligned and installed.

[0063] In one specific embodiment of this utility model, the automobile opening and closing component 1 includes a sheet metal part 10, a mounting hole 11 and a marking part 12 are both provided on the sheet metal part 10, and the marking part 12 is configured as a notch located at the outer edge of the mounting hole 11.

[0064] Using the above technical solution, the notch at the outer edge of the mounting hole 11 can serve as a "guide groove" when the buffer block 2 is inserted into the mounting hole 11. The external thread 201 of the buffer block 2 can be aligned with the notch, reducing the difficulty of alignment during assembly.

The buffer block 2 is a buffer block 2 integrating multiple main positioning scales 211. The buffer block 2 can be adapted to the car opening and closing components 1 such as trunk lids, doors, and hoods on the same model of car, and can also be adapted to different models of car opening and closing components 1 such as trunk lids, doors, and hoods on different models of cars.
