Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to a detection device. Background Art

[0002] There are many parameters used to measure whether various indicators meet the standards in vehicles. Among them, gap and flushness is an important indicator used to measure the external assembly quality of automobiles or other products. Specifically, whether the gaps between various parts of the vehicle body are appropriate can be seen from whether they meet the gap and flushness standards.

[0003] There are many ways to measure the gap between various components. In the prior art, when measuring the gap between the fender and the front door of a vehicle, a specific measuring device is usually used. A gap block that meets the gap surface difference is set in advance in the measuring device so that the gap between the fender and the front door is the same size as the gap block. In this way, the gap between the fender and the front door meets the specification.

[0004] However, the gap face difference standards between the fender front doors of vehicles of different models are different, and the sizes of the gap blocks used are different. In the actual production and assembly process, the gap blocks need to be frequently replaced, which increases the workload and affects the production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Unless otherwise specified, the above-mentioned directional description can be flexibly set in the process of actual application under the condition that the relative positional relationship shown in the accompanying drawings is satisfied.

[0040] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. It can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] In the embodiments of the present invention, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, article or device including the element.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0044] like Figure 1 As shown, Figure 1 The schematic diagram of the structure of a vehicle provided by the utility model, the vehicle 1 may include a chassis 2, a body 3 and wheels 4. It is understandable that the vehicle 1 may be a fuel vehicle, an electric vehicle, a hybrid vehicle, a gas vehicle, a methanol vehicle, a solar vehicle, etc. Exemplarily, the vehicle 1 may be a passenger vehicle such as a sedan, a sport utility vehicle (SUV), a multi-purpose vehicle (MPV), or a bus, a truck, a semi-trailer, etc. This application does not make specific restrictions on this.

[0045] Exemplarily, the present application is described using an electric car as an example.

[0046] The chassis 2 can be used to install the motor and other components of the vehicle 1 to form the overall shape of the vehicle 1, and receive the power of the motor to make the vehicle 1 move to ensure normal driving.

[0047] The vehicle body 3 can be mounted on the chassis 2, and a cabin is formed inside the vehicle body 3, and the cabin can be used for the driver and passengers to sit or load cargo. It should be noted that when the vehicle 1 is a bus or a car, its vehicle body 3 is generally an integral structure. When the vehicle 1 is a truck, its vehicle body 3 is generally composed of a cab and a cargo box.

[0048] The wheels 4 can be mounted on the chassis 2 of the vehicle 1, and are components that support and rotate the vehicle 1 during travel. The wheels 4 are usually mounted at the four corners of the vehicle 1, i.e., the four wheels 4 of the vehicle 1, which are connected to the axle of the vehicle 1 through the wheel hubs, so that the vehicle 1 can travel smoothly on the ground.

[0049] The body 3 of the vehicle 1 may include components such as rear doors, front doors, fenders, and a hood, etc. In order to ensure the operability of each component, there will be a certain gap between each adjacent component, and the gap sizes between different components are also different.

[0050] The rear doors, front doors and hood of the vehicle body 3 are all assembled and installed as a whole through the assembly frame, and then the fenders and front doors are installed and the gaps are adjusted. When assembling the various parts of the vehicle body 3, a specific detection device is usually used to detect whether the gaps between the various parts meet the requirements.

[0051] It is understandable that the above components are merely examples of some components of the vehicle 1 and are not limitations on the specific structure of the vehicle 1 .

[0052] In related technologies, such as Figure 2 As shown, Figure 2 Schematic diagram of the structure of the detection device in the prior art. When the detection device 010 is used to detect the gap between the fender and the front door, the determination is mainly made through the gap block 020 in the detection device 010. In the prior art, the gap block 020 is flat and has a fixed thickness. Different models of vehicles need to use different sizes of gap blocks 020. Therefore, when measuring the gap between the fender and the front door of different models, it is necessary to replace the gap blocks 020 of different sizes and specifications. In this way, the workload in actual assembly and measurement is large and the work efficiency is low.

[0053] Based on this, the utility model provides a detection device, such as Figure 3 and Figure 4 As shown, Figure 3 This is one of the overall structural diagrams of a detection device 100 provided by the utility model. Figure 4 It is a structural schematic diagram of the gap block 40 provided by the utility model, comprising a base 10, a first connecting structure 20, a second connecting structure 30, a gap block 40 and a length detection structure 50.

[0054] The first connection structure 20 and the second connection structure 30 are located on the same side of the base 10 and connected to the base 10, and the first connection structure 20 and the second connection structure 30 are arranged at intervals along the first direction X. The gap block 40 is connected to the base 10 and is movable relative to the base 10 along a second direction Y perpendicular to the first direction X. The gap block 40 includes a tapered portion 41, which is located between the first connection structure 20 and the second connection structure 30. The tapered portion 41 has a larger cross-sectional end and a smaller cross-sectional end, and the smaller cross-sectional end is located on the side of the larger cross-sectional end facing away from the base 10. The length detection structure 50 is used to detect the moving distance of the gap block 40 relative to the base 10.

[0055] In the detection device 100 provided in the embodiment of the present application, the first connection structure 20 and the second connection structure 30 can connect the components arranged along the first direction X on the side facing away from the base 10. By manipulating the gap block 40 to move along the second direction Y, the size of the cross-sectional area of ​​the tapered portion 41 with different cross-sectional areas at a specific position can be changed, so that the distance between the two ends of the tapered portion 41 at the specific position along the first direction X can be changed.

[0056] And the distance between the two ends of the tapered portion 41 at a specific position along the first direction X is related to the distance that the gap block 40 moves in the second direction Y. By using the length detection structure 50 to measure the distance that the gap block 40 moves relative to the base 10 in the second direction Y, the distance between the two ends of the tapered portion 41 at a specific position along the first direction X can be obtained.

[0057] Therefore, the distance between the two ends of the tapered portion 41 along the first direction X can be adjusted by adjusting the distance that the gap block 40 moves along the second direction Y, so that the detection device 100 can detect the gap between the fender and the front door of different vehicle models, thereby making it compatible with different vehicles.

[0058] Moreover, the structure of the detection device 100 is relatively simple, and the storage space requirement is small, which avoids the risk of easy loss of components to a certain extent, and also improves the speed of assembly production and the welding production rhythm.

[0059] When the detection device 100 is used to detect the distance between the fender and the front door, the end of the first connection structure 20 facing away from the base 10 can be detachably connected to the fender, and the end of the second connection structure 30 facing away from the base 10 can be detachably connected to the front door. The tapered portion 41 is located between the opposite surfaces of the fender and the front door, and the two ends of the tapered portion 41 along the first direction X respectively contact the opposite surfaces of the fender and the front door.

[0060] At this time, the distance between the two contact points of the tapered portion 41 along the first direction X is the gap between the fender and the front door. By using the length detection structure 50 to measure the distance that the gap block 40 moves relative to the base 10 in the second direction Y, the change length of the distance between the two contact points of the tapered portion 41 along the first direction X can be known, thereby knowing the gap between the fender and the front door.

[0061] If the gap value between the fender and the front door is within the gap surface difference range, it means that the assembly between the fender and the front door is qualified, and there is no need to adjust the assembly distance between the fender and the front door subsequently.

[0062] If the gap value between the fender and the front door is not within the gap face difference range, it means that the assembly between the fender and the front door is unqualified, and the position of the fender needs to be adjusted later. During the adjustment process, the detection device 100 needs to be disconnected from the fender and the front door to facilitate the assembly adjustment of the fender and the front door.

[0063] After adjusting the distance between the fender and the front door, the detection device 100 is used to measure the gap between the fender and the front door again to see whether the gap value is within the gap flushness range. If it is within the range, it needs to be adjusted again until the gap value is within the gap flushness range.

[0064] Exemplarily, when the first connection structure 20 and the second connection structure 30 are connected to the base 10 , they are connected by using pins.

[0065] In some embodiments, Figure 4 As shown, the tapered portion 41 may be in a conical shape.

[0066] No matter which angle the conical tapered portion 41 is rotated to, the distance between the contact point between the fender and the front door along the first direction X can be the same. In this way, the accuracy and stability of the gap block 40 in measuring the gap between the fender and the front door can be ensured.

[0067] In other embodiments, the tapered portion 41 may also be in a pyramid shape. The pyramid shape can also achieve that when the gap block 40 moves along the second direction Y, the distance between the two ends of the tapered portion 41 at a specific position along the first direction X changes with the movement of the gap block 40.

[0068] The tapered shape of the tapered portion 41 is not particularly limited, as long as the distance between both ends of the tapered portion 41 at a specific position along the first direction X can be changed as the gap block 40 moves.

[0069] In some embodiments, the cone angle of the cone portion 41 may be greater than or equal to 52.9° and less than or equal to 53.2°.

[0070] The range of the taper angle should not be too large or too small. When the taper angle of the tapered portion is greater than or equal to 52.9° and less than or equal to 53.2°, the gap block 40 moves 1 mm along the second direction Y. At this time, the length of the tapered portion 41 at a specific position between the two ends along the first direction X is also approximately 1 mm.

[0071] By measuring the distance that the gap block 40 moves along the second direction Y, the length of the change in value between the two ends of the tapered portion 41 at a specific position along the first direction X can be directly known through transformation. Thus, the change value of the gap between the fender and the front door is known to determine the specific value of the gap between the fender and the front door.

[0072] Specifically, the cone angle of the cone portion 41 may be 52.9°, 52.95°, 53°, 53.1°, 53.15° or 53.2°.

[0073] In some embodiments, the cone angle of the cone portion 41 may be greater than or equal to 52.95° and less than or equal to 53.15°.

[0074] The smaller the range of the taper angle of the tapered portion 41 is, the closer the length of the tapered portion 41 between two ends along the first direction X at a specific position can be to the distance the gap block 40 moves along the second direction Y.

[0075] Specifically, the cone angle of the cone portion 41 may be 52.95°, 52.96°, 52.98°, 53°, 53.05°, 53.1° or 53.15°.

[0076] For example, Figure 5 As shown, Figure 5 This is a partial structural diagram of the gap block 40 provided by the utility model. Before the gap block 40 moves, the spacing value between the two ends of the tapered portion 41 at a specific position along the first direction X can be D=4mm. After the gap block 40 moves, the spacing value between the two ends of the tapered portion 41 at a specific position along the first direction X can be d=3mm. And the distance L2 of the gap block 40 moving along the second direction Y is 1mm.

[0077] Because the cross section of the pyramid along the first direction X is an isosceles trapezoid, L1 = 0.5 mm. The length of the hypotenuse of the isosceles trapezoid can be calculated by the Pythagorean theorem:

[0078]

[0079] From the tangent formula, we know that the angle between L2 and the hypotenuse L is:

[0080] tanα=L1 / L2=0.5 / 1=1 / 2

[0081]

[0082] It can be seen that when the cone angle of the cone portion 41 is approximately 53°, it can ensure that when the gap block 40 moves 1 mm in the second direction Y, the length of the distance between the two ends of the cone portion 41 at a specific position in the first direction X also changes to approximately 1 mm.

[0083] In some embodiments, Figure 4 Shown and Figure 6 As shown, Figure 6 The schematic diagram of the structure of the threaded sleeve 12 provided by the utility model is as follows: the gap block 40 may further include a stud portion 42 connected to the tapered portion 41. The base 10 is provided with a threaded hole 101, the threaded hole 101 extends along the second direction Y, and the stud portion 42 is threadedly connected in the threaded hole 101.

[0084] The stud portion 42 can be threadedly connected to the base 10 through the threaded hole 101, so that the gap block 40 can be threadedly connected to the base 10. When the stud portion 42 is threadedly connected to the base 10 and rotates relative to the base 10, the stud portion 42 will also move relative to the base 10 along the second direction Y, thereby driving the conical tapered portion 41 connected to the stud portion 42 to rotate and move relative to the base 10.

[0085] When the conical tapered portion 41 rotates, the distance between the two ends thereof at a specific position along the first direction X will not change.

[0086] The spiral motion can achieve very precise position control and fine adjustment, and can accurately control the distance that the stud portion 42 moves along the second direction Y. In addition, the threaded connection has a certain self-locking property, and can maintain the position without an additional locking mechanism, preventing the gap block 40 from loosening due to external force or vibration. This provides safety protection for the gap block 40 that needs to be fixed in a stable position.

[0087] In some other embodiments, the gap block 40 further includes a moving portion connected to the tapered portion 41. The base 10 is provided with a moving hole extending along the second direction Y, and the moving portion is slidably connected in the moving hole.

[0088] In some embodiments, Figure 7 As shown, Figure 7 The second schematic diagram of the overall structure of a detection device 100 provided by the utility model, the base 10 may include a base body 11 and a threaded sleeve 12. The base body 11 is provided with a mounting hole 102, the mounting hole 102 extends along the second direction Y, the threaded sleeve 12 is installed in the mounting hole 102, and the threaded hole 101 is provided in the threaded sleeve 12.

[0089] The threaded sleeve 12 is installed in the threaded hole 101 extending along the second direction Y, so that the threaded portion and the threaded sleeve 12 can be in contact with each other for threaded connection. Because long-term threaded connection will cause wear between the threaded hole 101 and the threaded portion, the threaded sleeve 12 can prevent the threaded portion and the base body 11 from being damaged due to wear, and can protect the integrity of the base body 11.

[0090] At the same time, the threaded sleeve 12 can be replaced after being damaged, and it is more convenient to replace the threaded sleeve 12 than to replace the base body 11 .

[0091] For example, the strength of the threaded sleeve 12 may be relatively weak. The threaded sleeve 12 with relatively weak strength can partially protect the threaded portion, preventing the threaded portion from being damaged by a large number of threaded connections.

[0092] In some embodiments, the base 10 may further include a blocking portion 13. The blocking portion 13 is located on one side of the base body 11 close to the first connection structure 20 and connected to the base body 11. The blocking portion 13 is located at the threaded hole 101 and can strengthen the connection strength between the tapered portion 41 and the base body 11.

[0093] In some embodiments, Figure 7 and Figure 8 As shown, Figure 8 The schematic diagram of the structure of the top screw provided by the utility model is that the base 10 can be provided with a top screw hole 103, the axial direction of the top screw hole 103 intersects or is perpendicular to the axial direction of the threaded hole 101, and one end of the top screw hole 103 passes through the side wall of the base 10, and the other end is connected to the threaded hole 101. The detection device 100 also includes a top screw 60. The top screw 60 includes a main body 61, which is accommodated in the top screw hole 103 and is movable along the axial direction of the top screw hole 103.

[0094] The top screw 60 can be located in the threaded hole 101 through the top screw hole 103 and contact the gap block 40. When the position of the gap block 40 is determined, the top screw 60 can be moved in the top screw hole 103 to make the top screw 60 contact the gap block 40, and a force intersecting or perpendicular to the axial direction of the threaded hole 101 is applied to the gap block 40, so that the gap block 40 is difficult to move in the second direction Y. In this way, the stability of the position of the gap block 40 and the accuracy of the measurement are guaranteed.

[0095] When the gap block 40 needs to be moved in the threaded hole 101 , the top screw 60 can be manipulated to move in the top screw hole 103 in a direction away from the threaded hole 101 , so that the top screw 60 will not affect the movement of the gap block 40 in the threaded hole 101 .

[0096] For example, the axial direction of the top screw hole 103 may be perpendicular to the first direction X and perpendicular to the second direction Y.

[0097] In other embodiments, the axial direction of the top screw 60 may be only perpendicular to the second direction Y. The axial direction of the top screw 60 is not specifically limited, as long as it can fix the position of the gap block 40 to a certain extent when the distance of the gap block 40 does not need to be adjusted.

[0098] In some embodiments, Figure 7 and Figure 8 As shown, the top screw 60 may further include a first handle 62 . The first handle 62 is disposed on a side of the top screw hole 103 facing away from the threaded hole 101 , and the first handle 62 is fixed to the main body 61 .

[0099] The first handle 62 , which is located on the side of the top screw hole 103 facing away from the threaded hole 101 and fixed to the main body 61 , can facilitate the staff to move the top screw 60 toward or away from the threaded hole 101 .

[0100] For example, Figure 8 As shown, the first handle 62 may be spherical. The spherical first handle 62 provides better comfort when in use, and facilitates the operation of the top screw 60 by the staff.

[0101] In other embodiments, the first handle 62 may also be in the shape of a cube. The first handle 62 may also be in other shapes, as long as the staff can move the main body 61 along the direction of the top screw hole 103 by manipulating the first handle 62 .

[0102] Exemplarily, the main body 61 slides in the top screw hole 103 along the axis of the top screw hole 103 .

[0103] In other embodiments, the inner wall of the top screw hole 103 may have threads, and the outer wall of the main body 61 may have threads matching the inner wall of the top screw hole 103 , so that the main body 61 can be threadedly connected with the top screw hole 103 .

[0104] For example, Figure 8 As shown, the main body portion 61 may be in a stepped shape, and the stepped main body portion 61 can save manufacturing materials to a certain extent.

[0105] In some embodiments, Figure 8 As shown, the top screw 60 may further include a contact portion 63. The contact portion 63 is located at a side of the main body 61 close to the threaded hole 101 and is used to contact the gap block 40.

[0106] For example, the contact portion 63 may be made of rubber. Rubber is relatively soft, and the soft material will not damage the gap block 40 when in contact with the gap block 40 .

[0107] In some embodiments, Figure 3 and Fig. 9 As shown, the gap block 40 may further include a first scale portion 43. The length detection structure 50 includes a scale plate 51, which is fixed on the base 10 and has a plurality of second scale portions 511 arranged along the second direction Y.

[0108] The second scale portion 511 on the scale plate 51 can measure the distance between the first scale portion 43 and the side of the base body 11 close to the first scale portion 43 and the scale plate 51. In this way, the staff can know the change of the distance between the two ends of the tapered portion 41 along the first direction X through the distance measured by the second scale.

[0109] Exemplarily, the interval between two adjacent second scale portions 511 may be 0.1 mm, that is, the accuracy of the scale plate 51 is 0.1 mm.

[0110] In other embodiments, the accuracy of the scale plate 51 may also be 0.2 mm. The accuracy of the scale plate 51 is not specifically limited, as long as it can measure the distance between the first scale portion 43 and the side of the base body 11 close to the first scale portion 43 and the scale plate 51 .

[0111] For example, the first scale portion 43 and the second scale portion 511 may be straight lines. The straight lines can make it easier to align the first scale portion 43 and the second scale portion 511, and make it easier for the dial 51 to accurately measure the distance between the first scale portion 43 and the side of the base body 11 close to the first scale portion 43 and the dial 51.

[0112] In other embodiments, the first scale portion 43 and the second scale portion 511 may be dots.

[0113] For example, Fig. 9 As shown, Fig. 9 The length detection structure 50 provided by the utility model is a schematic diagram of the structure, and the length detection structure 50 may also include a fixing member 52. The fixing member 52 is located on one side of the scale plate 51 and is connected to the scale plate 51. The fixing member 52 can be fixedly connected to the base 10, so that the scale plate 51 is fixedly connected to the base 10.

[0114] In some embodiments, Figure 4 and Figure 7 As shown, the gap block 40 may further include a second handle 44, which is located on a side of the base 10 facing away from the tapered portion 41, and the second handle 44 is fixed to the tapered portion 41. The dial 51 is located on a side of the base 10 facing away from the tapered portion 41.

[0115] The second handle 44 , which is located on the side of the base 10 facing away from the tapered portion 41 and is fixed to the tapered portion 41 , facilitates the operator to control the gap block 40 to move along the second direction Y.

[0116] For example, Figure 7 As shown, the second handle 44 may be cylindrical in shape. The cylindrical second handle 44 is convenient for workers to operate the gap block 40.

[0117] In other embodiments, the second handle 44 may also be in the shape of a cuboid. The shape of the second handle 44 is not specifically limited, as long as the operator can control the gap block 40 to move along the second direction Y through the second handle 44 .

[0118] In some embodiments, an edge of the second handle 44 facing the base 10 may form a first scale portion 43 .

[0119] The edge of the second handle 44 facing the base 10 is linear, and the linear first scale portion 43 is more easily aligned with the second scale portion 511 , which is beneficial to increase the measurement accuracy of the dial 51 , thereby increasing the measurement accuracy of the detection device 100 .

[0120] In other embodiments, the first scale portion 43 may also be located on the second handle 44. The first scale portion 43 may be a linear concave portion or a linear convex portion.

[0121] Similarly, the second scale may also be a linear recessed portion or a linear raised portion.

[0122] In some embodiments, Figure 7 As shown, the length detection structure 50 may further include a first gasket 53 , which is disposed between the dial 51 and the base 10 .

[0123] When the detection device 100 measures the gap between the fender and the front door of vehicles of different models, the position of the first scale will change, making it impossible for the first scale to be aligned with the zero scale line of the dial 51. The staff needs to obtain the distance of the position displacement and perform further calculations, which is not conducive to the staff's intuitive reading.

[0124] The first gasket 53 is provided between the scale plate 51 and the base 10 to align the zero scale line of the scale plate 51 with the first scale, so that the staff can read the degree intuitively. Specifically, the thickness of the first gasket 53 varies according to the different vehicle models detected by the detection device 100.

[0125] In some embodiments, Figure 3 and Figure 7 As shown, the first connection structure 20 and the second connection structure 30 may include a main body 21 and at least one magnetic member 22 , wherein the main body 21 is connected to the base 10 , and the at least one magnetic member 22 is connected to the end of the main body 21 facing away from the base 10 .

[0126] The magnetic member 22 can attract the fender and the front door, so that the fender and the front door can be detachably connected to the first connection structure 20 and the second connection structure 30. Compared with other detachable structures, the magnetic connection method does not require too many other connection structures, and will not cause damage to the fender and the front door when connecting them.

[0127] Exemplarily, a magnetic attraction groove may be provided on a side of the first connection structure 20 and the second connection structure 30 facing away from the base 10 , and the magnetic attraction member 22 is disposed in the magnetic attraction groove.

[0128] In other embodiments, the detection device 100 may further include two vacuum suction cups, the two vacuum suction cups are respectively connected to the first connecting structure 20 and the second connecting structure 30 on the side facing away from the base 10, and the two vacuum suction cups are respectively adsorbed and detachably connected to the fender and the front door.

[0129] In some embodiments, the main body 21 may be a non-metallic member.

[0130] In other embodiments, the main body 21 may also be a metal part.

[0131] In some embodiments, the main body 21 may be a resin member.

[0132] The resin parts are relatively soft and will not cause damage to the fenders and front doors when they come into contact with the fenders and front doors for detachable connection.

[0133] For example, the material of the resin part can be polyester resin. Polyester resin has good chemical resistance and weather resistance, and can be used for a long time without deformation. In addition, the raw materials of polyester resin are relatively cheap, the production cost is low, and the cost performance is high.

[0134] In other embodiments, the main body 21 may be a plastic part.

[0135] Exemplarily, the size of the main body 21 is 20 mm×20 mm.

[0136] In some embodiments, Figure 3 As shown, the first connection structure 20 and the second connection structure 30 may further include a second gasket 23 , and the second gasket 23 is disposed between the main body 21 and the base 10 .

[0137] When the detection device 100 measures the gap between the fender and the front door of vehicles of different models, the position of the tapered portion 41 can be moved freely in the second direction Y, and when the tapered portion 41 moves to the position closest to the base 10 along the second direction Y, the fender and the front door connected by the first connecting structure 20 and the second connecting structure 30 cannot conflict with the tapered portion 41.

[0138] Therefore, the second gasket 23 is required to make the ends of the first connection structure 20 and the second connection structure 30 facing away from the base 10 further away from the base 10 so that the opposite surfaces between the fender and the front door can collide with the tapered portion 41 .

[0139] At the same time, the required thickness of the second gasket 23 is different for fenders and front doors of vehicles of different models.

[0140] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0141] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
