Description

Technical Field

[0001] This application relates to the field of vehicle body technology, and in particular to a screwed structure and a vehicle. Background Technology

[0002] Screwed connections are one of the most widely used and reliable connection methods in automobile body assembly. For example, the roof panel of a vehicle is installed on the roof using a screwed connection, which may include nuts and bolts.

[0003] In vehicle assembly, nuts are usually transported along with the parts to be assembled (such as roof trim panels). However, due to the problem of unreliable nut installation in traditional nut installation structures, nuts are prone to falling off during the transportation of the parts to be assembled, which affects the subsequent assembly efficiency of the parts and is not conducive to improving the overall vehicle assembly efficiency. Utility Model Content

[0004] In view of this, this application aims to propose a screw connection structure that is beneficial to improving the assembly efficiency of the whole vehicle.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A screwed structure is provided on a vehicle body, including a mounting boss and an elastic baffle provided on the vehicle body, and also including a nut; The mounting boss has a receiving cavity, and the top of the mounting boss has a first opening, and the side of the mounting boss has a second opening. The elastic baffle is located at the second opening. When the elastic baffle is pressed, the nut can be inserted into the receiving cavity from the second opening and correspond to the first opening. After being reset, the elastic baffle restricts the nut within the receiving cavity.

[0006] Furthermore, the vehicle body is provided with weakening grooves located on both sides of the elastic baffle.

[0007] Furthermore, the second opening is connected to the first opening.

[0008] Furthermore, the nut has a columnar main body, and a first plate and a second plate located at both ends of the main body; when the nut is installed into the receiving cavity, the main body is slidably disposed in the first opening, and the first plate is located outside the mounting boss, while the second plate is located inside the receiving cavity.

[0009] Furthermore, a guide ramp is provided at one end of the first opening that connects to the second opening, and the guide ramp is adapted to guide the main body into the first opening.

[0010] Furthermore, the inner wall of the first opening is provided with a plurality of first protrusions, which limit the main body within a predetermined area in the first opening.

[0011] Furthermore, the mounting boss is provided with a second protrusion located within the receiving cavity, and the side wall of the second plate abuts against the second protrusion, thereby restricting the nut from rotating relative to the mounting boss.

[0012] Compared with related technologies, this application has the following advantages: (1) The screw connection structure described in this application provides a first opening on the top of the mounting boss with a receiving cavity, a second opening on the side of the mounting boss, and an elastic baffle at the second opening. When the elastic baffle is pressed, the nut can be inserted into the receiving cavity from the second opening and correspond to the first opening. The elastic baffle after resetting restricts the nut in the receiving cavity. This not only enables convenient installation and removal of the nut, but also prevents the nut from falling off, solves the problem of traditional nuts falling off due to insecure installation, ensures the assembly efficiency of the parts to be assembled, and thus helps to improve the assembly efficiency of the whole vehicle.

[0013] (2) By setting weakening grooves on both sides of the elastic baffle on the vehicle body, the elastic baffle can be more easily deformed when pressed, which solves the problem of the elastic baffle being difficult to deform, and helps to improve the ease of nut disassembly and assembly, as well as the structural durability of the elastic baffle.

[0014] (3) The second opening is connected to the first opening, which makes it easier for the screw hole of the nut to be aligned with the first opening, thus improving the convenience of subsequent use of the nut.

[0015] (4) The nut is in the shape of a column, and the first plate and the second plate are located at both ends of the main body. At the same time, when the nut is installed in the receiving cavity, the main body is slidably placed in the first opening, and the first plate is located outside the mounting boss, and the second plate is located inside the receiving cavity. The first plate and the second plate can be used to limit the nut in the direction of the main body axis to prevent the nut from falling off from the direction of the main body axis.

[0016] (5) By setting a guide ramp at one end of the first opening and the second opening to guide the main body into the first opening, the difficulty of disassembling and assembling the nut can be reduced and its ease of disassembly and assembly can be improved.

[0017] (6) By providing multiple first protrusions on the inner wall of the first opening, and by limiting the main body in a preset area in the first opening, the nut can be further prevented from falling off on the basis of the elastic baffle limiting the nut, thus avoiding affecting the subsequent use of the nut.

[0018] (7) By setting a second protrusion on the mounting boss that can restrict the rotation of the nut relative to the mounting boss, the assembly difficulties caused by the rotation of the nut and the insufficient structural stability after assembly can be avoided, thereby improving the overall quality of the vehicle.

[0019] This application also proposes a vehicle in which the vehicle body is provided with the bolted structure described above.

[0020] Furthermore, the vehicle body has a roof trim panel, the screwed structure is provided on the trim panel frame in the roof trim panel, and the roof in the vehicle body is connected to the nut by a screw connector.

[0021] Furthermore, a sealing washer is provided between the top cover and the nut, and the sealing washer is fitted onto the threaded connector.

[0022] The vehicle described in this application has the aforementioned bolted structure on its body, which can solve the problem of nuts falling off due to insecure installation, reduce the risk of reconfiguring nuts after they fall off, and help ensure the assembly efficiency of the parts to be assembled, thereby improving the overall vehicle assembly efficiency.

[0023] In addition, by placing a sealing washer between the top cover and the nut, and with the sealing washer fitted onto the threaded connection, the sealing performance between the top cover and the top cover trim panel can be improved, reducing the risk of water ingress at the threaded connection. At the same time, it can also ensure the installation stability of the sealing washer. Attached Figure Description

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0031] An embodiment of the first aspect of this application provides a screw-on structure that is mounted on the vehicle body, which can solve the problem that traditional nuts 200 are prone to falling off due to insecure installation, thereby improving the assembly efficiency of the whole vehicle.

[0032] In related technologies, bolted connections are one of the most widely used and reliable connection methods in automotive body assembly. With advantages such as detachability, controllable connection strength, and adaptability to complex working conditions, they are used in many key parts of the vehicle body, from the frame to the outer body panels, and from the chassis to the interior accessories. For example, the roof panel 300 of a vehicle is mounted on the roof 600 via a bolted connection, and this bolted connection may include, for example, a nut 200 and a bolt.

[0033] In vehicle assembly, nuts 200 are usually transported together with the parts to be assembled (such as roof trim 300). However, due to the problem that the traditional nut 200 installation structure is not secure, nuts 200 are prone to falling off during the transportation of the parts to be assembled, which affects the subsequent assembly efficiency of the parts to be assembled and is not conducive to improving the overall vehicle assembly efficiency.

[0034] In view of this, in order to overcome the shortcomings of related technologies, the screw connection structure in this embodiment combines... Figures 1 to 10 As shown, in terms of overall design, it is mounted on the vehicle body and includes a mounting boss 100, an elastic baffle 1031 and a nut 200 mounted on the vehicle body.

[0035] The mounting boss 100 has a receiving cavity 1000, and the top of the mounting boss 100 has a first opening 1010, while the side of the mounting boss 100 has a second opening 1020. Furthermore, an elastic baffle 1031 is located at the second opening 1020. When the elastic baffle 1031 is pressed, the nut 200 can be inserted into the receiving cavity 1000 through the second opening 1020, corresponding to the first opening 1010. After resetting, the elastic baffle 1031 retains the nut 200 within the receiving cavity 1000.

[0036] Therefore, by forming a receiving cavity 1000 within the mounting boss 100, and having a first opening 1010 at the top of the mounting boss 100 and a second opening 1020 on the side of the mounting boss 100, and by placing an elastic baffle 1031 at the second opening 1020, when the elastic baffle 1031 is pressed, the nut 200 can be inserted into the receiving cavity 1000 through the second opening 1020 and correspond to the first opening 1010. After resetting, the elastic baffle 1031 restricts the nut 200 within the receiving cavity 1000. This not only enables convenient installation and removal of the nut 200, but also prevents the nut 200 from falling off, solving the problem of the traditional nut 200 falling off due to insecure installation, ensuring the assembly efficiency of the parts to be assembled, and thus improving the overall vehicle assembly efficiency.

[0037] Based on the above general introduction, specifically, in some exemplary embodiments, the screw connection structure of this embodiment is particularly suitable for the assembly and disassembly of the roof trim panel 300 on the roof 600 in the vehicle body. The roof trim panel 300 is a decorative component on the top of the vehicle, generally including a trim frame 302 and a trim body 301, and the trim frame 302 is usually connected to the outer panel of the roof by a screw connection structure to realize the connection between the roof trim panel 300 and the roof 600.

[0038] In the screw-in structure, the nut 200 is usually set on the trim panel frame 302 and is transported along with the roof trim panel 300 during the vehicle assembly process. However, due to the problem that the nut 200 is not securely installed in the traditional nut 200 installation structure, the nut 200 is prone to falling off during the transportation of the roof trim panel 300, which affects the subsequent assembly efficiency of the roof trim panel 300 and thus affects the improvement of the overall vehicle assembly efficiency.

[0039] Therefore, in the screw connection structure of this embodiment, based on the mounting boss 100, a receiving cavity 1000, a first opening 1010, a second opening 1020, and an elastic baffle 1031 are configured. The elastic baffle 1031 can be pressed and deformed so that the nut 200 can be inserted into the receiving cavity 1000 through the second opening 1020 and correspond to the first opening 1010. The elastic baffle 1031, after being reset, restricts the nut 200 within the receiving cavity 1000, thereby solving the problem of the nut 200 falling off.

[0040] The nut 200 is installed in the receiving cavity 1000 and is set to correspond to the first opening 1010. This means that the axis of the screw hole 2000 of the nut 200 is aligned with the axis of the first opening 1010. In other words, the screw connector 500 can be smoothly screwed into the screw hole 2000 of the nut 200 after passing through the first opening 1010. This ensures the normal use of the nut 200.

[0041] Of course, the screw connection structure in this embodiment is not limited to the connection between the top cover panel 300 and the top cover 600. It can be applied to the assembly of exterior trim parts on the vehicle body, as well as the assembly of interior trim parts on the vehicle body. It can also be applied to other parts to be installed on the vehicle body when necessary, which will not be elaborated here.

[0042] Continue to combine Figures 1 to 3 As shown, in some exemplary embodiments, the mounting boss 100 of this embodiment includes a top wall 101 and a bottom wall 103 arranged vertically opposite each other, and a side wall 102 connecting the top wall 101 and the bottom wall 103. The bottom wall 103 is part of the vehicle body. Meanwhile, an elastic baffle 1031 is integrally formed on the bottom wall 103. A receiving cavity 1000 is formed between the top wall 101, the bottom wall 103 and the side wall 102. Corresponding to the receiving cavity 1000, the top wall 101 is provided with the first opening 1010, the side wall 102 is provided with the second opening 1020, and the bottom wall 103 is provided with a through groove communicating with the receiving cavity 1000.

[0043] Understandably, the second opening 1020 not only facilitates the arrangement of the elastic baffle 1031 and the disassembly and assembly of the nut 200, but also works with the first opening 1010 and the through slot to achieve a lightweight design for the screwed connection structure. At the same time, the through slot provides space for the deformation of the elastic baffle 1031, which helps to meet the different deformation requirements of the elastic baffle 1031 and enriches the use effect of the screwed connection structure.

[0044] It should be noted that the direction-related descriptions in this embodiment are merely illustrative examples. In actual implementation, the direction descriptions in this embodiment will vary depending on the orientation of the mounting boss 100; that is, each direction in this embodiment refers to a relative coordinate system with the mounting boss 100 as the reference.

[0045] Continue to combine Figures 1 to 3 As shown, in some exemplary embodiments, the vehicle body is provided with weakening grooves 1030 on both sides of the elastic baffle 1031, that is, the bottom wall 103 integrally formed with the vehicle body is provided with weakening grooves 1030.

[0046] The main advantage of this design is that it makes the elastic baffle 1031 easier to deform when pressed, solving the problem of the elastic baffle 1031 being difficult to deform, which helps to improve the ease of disassembly and assembly of the nut 200, as well as the structural durability of the elastic baffle 1031.

[0047] Continue to combine Figures 1 to 3 As shown, in some exemplary embodiments, the second opening 1020 communicates with the first opening 1010. This communication between the second opening 1020 and the first opening 1010 facilitates the alignment of the screw hole 2000 of the nut 200 with the first opening 1010, improving the ease of subsequent use of the nut 200.

[0048] Continue to combine Figures 1 to 4 As shown, in some exemplary embodiments, the nut 200 has a cylindrical body 201, and a first plate 202 and a second plate 203 located at both ends of the body 201. When the nut 200 is inserted into the receiving cavity 1000, the body 201 is slidably disposed in the first opening 1010, and the first plate 202 is located outside the mounting boss 100, while the second plate 203 is located inside the receiving cavity 1000.

[0049] It is understandable that the main body 201, which makes the nut 200 cylindrical, and the first plate 202 and the second plate 203 located at both ends of the main body 201, are used to limit the nut 200 in the receiving cavity 1000 when the nut 200 is installed in the receiving cavity 1000. The main body 201 is slidably disposed in the first opening 1010, and the first plate 202 is located outside the mounting boss 100, while the second plate 203 is located inside the receiving cavity 1000. The first plate 202 and the second plate 203 can be used to limit the nut 200 in the axial direction of the main body 201, so as to prevent the nut 200 from falling off in the axial direction of the main body 201.

[0050] In specific implementations, in some exemplary embodiments, the distance between the first plate 202 and the second plate 203 along the axial direction of the main body 201 (i.e., the height direction of the mounting boss 100) is the same as the thickness of the top wall 101 along the height direction of the mounting boss 100. This arrangement can effectively limit the nut 200 along the height direction of the mounting boss 100, preventing the nut 200 from moving along the height direction of the mounting boss 100.

[0051] Meanwhile, in some exemplary embodiments, the second opening 1020 is formed on one side wall 102 of the mounting boss 100 along its length direction, and the first opening 1010 extends along its length direction and communicates with the second opening 1020 so that the nut 200 can be installed from the side of the second opening 1020.

[0052] Furthermore, in some exemplary embodiments, the elastic baffle 1031 includes a first portion 10311, a second portion 10312, and a third portion 10313. The first portion 10311 is integrally formed with the bottom wall 103 and extends into the receiving cavity 1000 along the installation length direction. The projection of the third portion 10313 along the length direction of the mounting boss 100 at least partially overlaps with the projection of the nut 200 along the length direction of the mounting boss 100. That is, when the nut 200 moves along the mounting boss 100 to the second opening 1020 in the first opening 1010, it will be blocked by the third portion 10313 to prevent the nut 200 from falling off. The second portion 10312 connects the first portion 10311 and the third portion 10313, and along the length direction of the mounting boss 100, the second portion 10312 extends obliquely upward from the first portion 10311 to the third portion 10313.

[0053] Continue to combine Figures 1 to 3 As shown, in some exemplary embodiments, the end of the first opening 1010 that communicates with the second opening 1020 is provided with a guide ramp 1011, which is adapted to guide the body 201 into the first opening 1010.

[0054] It can be understood that by setting a guide ramp 1011 at the end where the first opening 1010 and the second opening 1020 are connected, the main body 201 can be guided into the first opening 1010, which can reduce the difficulty of disassembling and assembling the nut 200 and improve its ease of disassembly and assembly.

[0055] In specific implementations, in some exemplary embodiments, the aforementioned guide slopes 1011 are provided on both sides of the first opening 1010 along the width direction of the mounting boss 100, so that no matter which side of the nut 200 is closer to the first opening 1010 during installation, the guide slopes 1011 guide the nut 200 into the receiving cavity 1000.

[0056] In addition, continue to combine Figures 1 to 3 As shown, in some exemplary embodiments, the inner wall of the first opening 1010 is provided with a plurality of first protrusions 1012, which limit the body 201 to a predetermined region Q in the first opening 1010.

[0057] By providing a plurality of first protrusions 1012 on the inner wall of the first opening 1010, and by limiting the main body 201 in a preset area Q in the first opening 1010, the nut 200 can be further prevented from falling off, thus avoiding affecting the subsequent use of the nut 200, on the basis of the elastic baffle 1031 limiting the nut 200.

[0058] In some exemplary embodiments, the number and arrangement of the first protrusions 1012 can be set and adjusted according to the actual installation requirements of the main body 201 of the nut 200. Specifically, the first protrusions 1012 can be provided on the inner walls of both sides of the first opening 1010 along the width direction of the mounting boss 100, and the first protrusions 1012 on each side inner wall are two arranged at intervals along the length direction of the mounting boss 100, so that the line connecting the four first protrusions 1012 forms a rectangle, etc. Moreover, in some exemplary embodiments, in order to facilitate a better limiting effect on the main body 201, an arc-shaped surface adapted to the main body 201 is formed between the two first protrusions 1012 on each side inner wall.

[0059] Meanwhile, in some exemplary embodiments, the setting position of each of the first protrusions 1012 can be designed according to the actual installation error of the part to be assembled. That is, when the gap between the part to be assembled and the other part exceeds the tolerance during the assembly process, the position of the preset area Q, that is, the position of the nut 200, can be adjusted by adjusting the setting position of each of the first protrusions 1012, thereby reducing or eliminating the error gap and achieving a better assembly effect.

[0060] It is worth mentioning that the nut 200 in this embodiment preferably adopts the above-mentioned structural configuration including the main body 201, the first plate 202 and the second plate 203. In this case, the first opening 1010 and the second opening 1020 need to be connected to facilitate the installation of the nut 200 into the receiving cavity 1000 and the preset area Q.

[0061] However, if the nut 200 is a common nut 200 commonly used by those skilled in the art, this embodiment does not limit the first opening 1010 and the second opening 1020 to be connected. In this case, for example, the nut 200 can enter the receiving cavity 1000 through the second opening 1020, and the screw hole 2000 of the nut 200 itself is connected to the first opening 1010 in the height direction of the mounting boss 100, which can be used for subsequent screwing operations.

[0062] At the same time, continue to combine Figures 1 to 3 ,as well as Figure 9 As shown, in some exemplary embodiments, the mounting boss 100 has a second protrusion 1013 located within the receiving cavity 1000, the sidewall 102 of the second plate 203 abuts against the second protrusion 1013 and is able to restrict the nut 200 from rotating relative to the mounting boss 100.

[0063] It is understandable that by providing a second protrusion 1013 on the mounting boss 100 that can restrict the rotation of the nut 200 relative to the mounting boss 100, the problems of assembly difficulties caused by the rotation of the nut 200 and insufficient structural stability after assembly can be avoided, thereby improving the overall quality of the vehicle.

[0064] In specific implementations, in some exemplary embodiments, the second boss can be designed as a U-shaped structure to fit the second plate 203. In this way, the second boss can surround the three sides of the second plate 203 as a whole, effectively preventing the nut 200 from rotating relative to the mounting boss 100.

[0065] It is worth noting that, regarding the screw connection structure of this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still based on... Figures 1 to 10 As shown, it is provided on the vehicle body, and may include a mounting boss 100, a resilient baffle 1031 and a nut 200 provided on the vehicle body.

[0066] The mounting boss 100 has a receiving cavity 1000, and the top of the mounting boss 100 has a first opening 1010, and the side of the mounting boss 100 has a second opening 1020. Furthermore, the elastic baffle 1031 is located at the second opening 1020. When the elastic baffle 1031 is pressed, the nut 200 can be inserted into the receiving cavity 1000 through the second opening 1020 and correspond to the first opening 1010. After being reset, the elastic baffle 1031 restricts the nut 200 within the receiving cavity 1000.

[0067] The vehicle body is provided with weakening grooves 1030 on both sides of the elastic baffle 1031, and each weakening groove 1030 extends along the length direction of the mounting boss 100.

[0068] The second opening 1020 is connected to the first opening 1010.

[0069] The nut 200 is a columnar main body 201, and a first plate 202 and a second plate 203 located at both ends of the main body 201; and when the nut 200 is installed in the receiving cavity 1000, the main body 201 is slidably disposed in the first opening 1010, and the first plate 202 is located outside the mounting boss 100, and the second plate 203 is located inside the receiving cavity 1000.

[0070] The first opening 1010 is connected to the second opening 1020 by a guide slope 1011. The guide slope 1011 is adapted to guide the main body 201 into the first opening 1010. The guide slope 1011 is provided on both sides of the first opening 1010 along the width direction of the mounting boss 100.

[0071] The inner wall of the first opening 1010 is provided with a plurality of first protrusions 1012, which limit the main body 201 to a preset area Q in the first opening 1010.

[0072] The mounting boss 100 has a second protrusion 1013 located in the receiving cavity 1000. The side wall 102 of the second plate 203 abuts against the second protrusion 1013 and can restrict the nut 200 from rotating relative to the mounting boss 100.

[0073] In the preferred embodiment of the above screw connection structure, the specific settings and arrangements of the mounting boss 100, receiving cavity 1000, elastic baffle 1031, weakening groove 1030, nut 200, etc. can still be referred to the descriptions in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the mounting boss 100, receiving cavity 1000, elastic baffle 1031, weakening groove 1030, and nut 200 can also be referred to the descriptions in the above exemplary embodiments.

[0074] The screw connection structure of this embodiment adopts the above design. By pressing the elastic baffle 1031, the nut 200 can be inserted into the receiving cavity 1000 from the second opening 1020 and correspond to the first opening 1010. After resetting, the elastic baffle 1031 can restrict the nut 200 within the receiving cavity 1000. In this way, not only can the nut 200 be easily installed and removed, but the nut 200 can also be prevented from falling off, solving the problem of the traditional nut 200 falling off due to insecure installation, and ensuring the assembly efficiency of the parts to be assembled.

[0075] By incorporating a weakening groove 1030, the elastic baffle 1031 is made easier to deform when pressed, solving the problem of difficult deformation of the elastic baffle 1031. This improves the ease of assembly and disassembly of the nut 200 and enhances the structural durability of the elastic baffle 1031. A guide ramp 1011 is provided at the end connecting the first opening 1010 and the second opening 1020 to guide the main body 201 into the first opening 1010, reducing the difficulty of assembly and disassembly of the nut 200 and improving its ease of assembly and disassembly. The coordinated arrangement of the first protrusion 1012 and the second protrusion 1013 allows the nut 200 to be installed in a preset position and also restricts its rotation relative to the mounting boss 100, thereby improving the installation stability of the nut 200.

[0077] Continue to combine Figures 5 to 10 As shown, in some exemplary embodiments, the vehicle body has a roof panel 300, a screw-on structure is provided on the panel frame 302 in the roof panel 300, and the roof 600 in the vehicle body is connected to the nut 200 by a screw-on member 500. This roof panel 300 is the aforementioned bag-shaped accessory. The screw-on member 500 can specifically be a bolt well known to those skilled in the art.

[0078] In some exemplary embodiments, a sealing washer 400 is provided between the top cover 600 and the nut 200, and the sealing washer 400 is fitted onto the threaded connector 500. By providing a sealing washer 400 between the top cover 600 and the nut 200, and by fitting the sealing washer 400 onto the threaded connector 500, the sealing performance between the top cover 600 and the top cover trim 300 can be improved, reducing the risk of water ingress at the threaded connection. At the same time, it can also ensure the installation stability of the sealing washer 400.

[0079] In specific implementations, in some exemplary embodiments, the top cover trim 300 in this embodiment can be the rear trim of the top cover 600 or a spoiler that can serve a decorative function. The top cover trim 300 includes a trim frame 302 and a trim body 301 disposed on the trim frame 302. The two can be connected by screws, and if necessary, a positioning structure can also be provided between the two to improve the ease of assembly.

[0080] When the top cover trim panel 300 can be the rear trim panel of the top cover 600, continue to combine. Figure 5 As shown, the trim panel body 301 has a first mounting groove 3011 and a second mounting groove 3012 at the rear part along the front-rear direction of the vehicle. The first mounting groove 3011 and the second mounting groove 3012 can be adapted to install components such as cameras or high-mounted brake lights to meet the functional design requirements of the vehicle.

[0081] Furthermore, in some exemplary embodiments, the outer cover plate of the top cover 600 is connected to the nut 200 on the trim frame 302 by a screw connector 500. Specifically, the outer cover plate is provided with a mounting through hole, and the screw connector 500 passes through the mounting through hole and is screwed into the screw hole 2000 of the nut 200.

[0082] Moreover, in some exemplary embodiments, the number and arrangement of the screw-on structures on the roof trim 300 can be set and adjusted according to the connection requirements between the roof trim 300 and the roof 600. For example, along the left and right direction of the vehicle, the screw-on structures are arranged in five or six spaced intervals.

[0083] In this embodiment of the vehicle, by providing the screw connection structure in the embodiment of the first aspect of this application in the vehicle body, the problem of the nut 200 falling off due to improper installation can be solved, the risk of reconfiguring the nut 200 after it falls off is reduced, and the assembly efficiency of the top cover trim 300 on the top cover 600 is ensured, thereby improving the overall vehicle assembly efficiency.
