Positioning assembly, glass assembly, and vehicle

Abstract

The application relates to a positioning assembly, a glass assembly and a vehicle. The positioning assembly comprises a base and a peg column. The base is arranged on the glass. The peg column is rotatably arranged on the base and is inserted into a mounting hole of a metal plate part to position the glass on the metal plate part. The peg column can rotate relative to the base to have a first state and a second state. In the first state, the peg column is used to limit the metal plate part in the mounting hole. In the second state, the peg column is used to be spaced from the metal plate part in the mounting hole. After the glass and the metal plate part are fixed, the positioning assembly can avoid the metal plate part and the peg column from interfering with each other to cause local vibration or torsion and further produce abnormal sound, thereby improving the user experience.

Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a positioning component, a glass assembly, and a vehicle. Background Technology

[0002] Currently, automotive glass is typically bonded to sheet metal parts using adhesive. During installation, prongs are first installed on the glass, then inserted into mounting holes on the sheet metal part. The prongs fit snugly into the mounting holes to position the glass on the sheet metal. After the adhesive cures, the glass is firmly fixed to the sheet metal part.

[0003] However, with current glass mounting on sheet metal parts, the glass is prone to downward displacement due to its own weight before the adhesive cures. This causes the sheet metal parts to interfere with the mounting holes and even partially cut into the mounting posts. As a result, after the adhesive cures, local vibrations or torsion can easily occur between the sheet metal parts and the mounting posts, producing abnormal noises and affecting the user experience. Summary of the Invention

[0004] Therefore, it is necessary to provide a positioning component, glass assembly, and vehicle to address the problem of abnormal noises that easily occur between sheet metal parts and nails.

[0005] A positioning component, comprising:

[0006] A base for mounting on glass;

[0007] A pin is rotatably mounted on the base and used to insert into the mounting hole of the sheet metal part to position the glass on the sheet metal part. The pin can rotate relative to the base to have a first state and a second state. In the first state, the pin is used to limit the mutual positioning with the sheet metal part in the mounting hole. In the second state, the pin is used to be spaced apart from the sheet metal part in the mounting hole.

[0008] When the aforementioned positioning component is used to position glass on sheet metal parts, the pins in the first state can mutually limit each other with the sheet metal parts to position the glass. After the adhesive on the glass cures and the glass is fixedly connected to the sheet metal parts, the pins can be driven to rotate relative to the base to the second state, so that the pins are spaced apart from the sheet metal parts in the mounting holes, thus eliminating the relative limiting between the pins and the sheet metal parts. Therefore, after the glass and the sheet metal parts are fixed, the interference between the sheet metal parts and the pins can be avoided, which may cause local vibration or torsion and thus generate abnormal noise, thereby improving the user experience.

[0009] In one embodiment, the shortest distance between the pin and the wall of the mounting hole in the second state is greater than the shortest distance between the pin and the wall of the mounting hole in the first state; and / or,

[0010] In the second state, the shortest distance between the nail post and the wall of the mounting hole is greater than or equal to 0.2 mm.

[0011] In one embodiment, the nail post is capable of rotating at least 30° relative to the base about its own axis to switch from the first state to the second state.

[0012] In one embodiment, the base is provided with a mating groove, and the nail post includes a column part and a mating part connected to each other. The column part is used to be inserted into the mounting hole, and the mating part is rotatably disposed in the mating groove. The outer periphery of the mating part is provided with at least one first limiting plane, and the inner periphery sidewall of the mating groove is provided with at least one second limiting plane. In the second state, the first limiting plane and the second limiting plane are opposite to each other and mutually limit each other.

[0013] In one embodiment, the outer periphery of the mating part is provided with a third limiting surface, at least a portion of which protrudes radially outward relative to the first limiting plane. The third limiting surface is used to abut against the inner peripheral sidewall of the mating groove to prevent the mating part from continuing to rotate relative to the base.

[0014] In one embodiment, the base includes a first plate portion and a second plate portion that are opposite to and spaced apart from each other, the mating groove is disposed between the first plate portion and the second plate portion, and the nail post also includes a plate body portion, the plate body portion being connected to the post body portion and spaced apart from the mating portion, the first plate portion and the second plate portion limiting the mating portion on opposite sides of the mating portion, and the plate body portion limiting the second plate portion on the side of the second plate portion facing away from the mating portion.

[0015] In one embodiment, the nail post further includes a first limiting portion connected to the outer periphery of the plate body portion, and the base further includes a second limiting portion disposed on the side of the second plate body portion facing away from the mating portion and located on the outer periphery of the plate body portion. During the process of the nail post switching from the first state to the second state, the first limiting portion passes through the second limiting portion, and in the second state, the first limiting portion and the second limiting portion abut and limit each other.

[0016] In one embodiment, the outer contour of the cross-section of the column portion has different radial dimensions at at least two locations. In the first state, the location with the largest radial dimension of the outer contour of the cross-section of the column portion is mutually constrained by the sheet metal part.

[0017] In one embodiment, the column portion is further provided with an operating structure, which is used to cooperate with an operating tool to enable the operating tool to drive the nail column to rotate relative to the base.

[0018] A glass assembly includes glass and a positioning component as described in any of the above embodiments, wherein the base is fixed to the glass.

[0019] A vehicle includes a sheet metal part and a glass assembly as described above, the sheet metal part having mounting holes, the glass being fixed to the sheet metal part by adhesive, and studs being inserted into the mounting holes and spaced apart from the sheet metal part.

[0042] Please see Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is a schematic diagram of the positioning component 10 in some embodiments. Figure 2 This is a schematic diagram of the structure of the glass assembly 20 in some embodiments. Figure 3 This is a schematic diagram showing the structure of the nail post 11 inserted into the mounting hole 311 of the sheet metal part 31 in some embodiments. The positioning component 10 provided in this application can be used in the glass assembly 20, and the positioning component 10 is used to be disposed on the glass 21 of the glass assembly 20. The glass assembly 20 includes, but is not limited to, use in vehicles such as automobiles, for example, disposed on the body of the vehicle, and the glass assembly 20 includes, but is not limited to, the windshield, rear window, or side window of the vehicle. The vehicle also includes the sheet metal part 31, which can be used to form part of the vehicle body, and the glass assembly 20 is fixed to the sheet metal part 31.

[0043] The sheet metal part 31 has mounting holes 311. During the installation of the glass assembly 20 onto the sheet metal part 31 of the vehicle, the positioning component 10 is inserted into the mounting holes 311 to position the glass 21 relative to the sheet metal part 31. For example, during the installation of the glass assembly 20, the glass 21 is placed onto the sheet metal part 31, and the positioning component 10 is inserted into the mounting holes 311 to position the glass 21. After the adhesive between the glass 21 and the sheet metal part 31 has cured to fix the glass 21 and the sheet metal part 31 together, the installation of the glass assembly 20 onto the sheet metal part 31 is completed.

[0044] Further, in some embodiments, the positioning assembly 10 includes a base 12 and a pin 11. The base 12 is fixedly mounted on the glass 21, and the pin 11 is rotatably mounted on the base 12 and used to insert into the mounting hole 311 of the sheet metal part 31 to position the glass 21 on the sheet metal part 31. The pin 11 is rotatable relative to the base 12 to have a first state and a second state, as shown in the reference. Figure 3 As shown, in the first state, the pin 11 is used to mutually limit the movement of the sheet metal part 31 within the mounting hole 311 to position the glass 21. Simultaneously, the glass 21 is relatively fixed to the sheet metal part 31 by means of the mutual limiting effect between the pin 11 and the sheet metal part 31, until the adhesive between the glass 21 and the sheet metal part 31 cures to fix the glass 21 and the sheet metal part 31 together. (Reference) Figure 4 As shown, in the second state, the nail post 11 rotates within the mounting hole 311 relative to the first state to a position that is spaced apart from the sheet metal part 31 and does not mutually limit the sheet metal part 31.

[0045] Understandably, during the positioning process of glass 21 relative to sheet metal 31, and before the adhesive between glass 21 and sheet metal 31 has cured, the stud 11 can be in a first state to position and fix glass 21 through mutual limiting between stud 11 and sheet metal 31. Once the adhesive on glass 21 has cured, fixing glass 21 to sheet metal 31, the stud 11 can be rotated relative to base 12 to a second state, causing the stud 11 to be spaced apart from sheet metal 31 within mounting hole 311, thus eliminating the relative limiting between stud 11 and sheet metal 31. Therefore, after glass 21 and sheet metal 31 have cured, for example during vehicle operation, interference between sheet metal 31 and stud 11 can be avoided, preventing local vibration or torsion and thus abnormal noise, improving the user experience without affecting the positioning function of positioning component 10 for glass 21.

[0046] In some embodiments, the shortest distance between the stud 11 and the wall of the mounting hole 311 in the second state is greater than the shortest distance between the stud 11 and the wall of the mounting hole 311 in the first state. That is, as the stud 11 rotates relative to the base 12 within the mounting hole 311, the shortest distance between the stud 11 and the wall of the mounting hole 311 changes, thereby switching the stud 11 between the first and second states. In the first state, the stud 11 can abut against the sheet metal part 31, or there can be a certain gap between the stud 11 and the sheet metal part 31, as long as it can mutually limit the movement of the stud 11. For example, in some embodiments, the mounting hole 311 is approximately rectangular. In the first state, the shortest distance between the stud 11 and the wall of the mounting hole 311 in the width direction of the mounting hole 311 is 0.124 mm, which can mutually limit the movement of the stud 11 to position the glass 21.

[0047] refer to Figure 4 As shown, in some embodiments, in the second state, the shortest distance between the post 11 and the wall of the mounting hole 311, for example, the distance between the post 11 and the wall of the mounting hole 311 in the width direction of the mounting hole 311 is greater than or equal to 0.2 mm, so that there is sufficient clearance between the post 11 and the sheet metal part 31, avoiding interference between the post 11 and the sheet metal part 31 when the vehicle is driving on complex road conditions, which would cause abnormal noise.

[0048] In some embodiments, the nail post 11 can rotate at least 30° relative to the base 12 about its own axis to switch from a first state to a second state. For example, combined with Figure 3 and Figure 4 As shown, the nail post 11 rotates 30° clockwise around its own axis from its position in the first state to switch to the second state. In this embodiment, in the second state, the shortest distance between the nail post 11 and the wall of the mounting hole 311 in the width direction of the mounting hole 311 is 0.421 mm. Combined with... Figure 3 and Figure 5 As shown, the nail post 11 rotates 60° clockwise around its own axis from its position in the first state to switch to the second state. In this embodiment, in the second state, the shortest distance between the nail post 11 and the wall of the mounting hole 311 in the width direction of the mounting hole 311 is 1.108 mm. Combined with... Figure 3 and Figure 6 As shown, the nail post 11 rotates 90° clockwise around its own axis from its position in the first state and then switches to the second state. In this embodiment, the shortest distance between the nail post 11 and the wall of the mounting hole 311 in the width direction of the mounting hole 311 is 1.524mm.

[0049] Of course, the angle and direction of rotation of the nail post 11 when switching from the first state to the second state are not limited to those described in this application. As long as there is enough gap between the nail post 11 and the sheet metal part 31 to eliminate the mutual restriction between the nail post 11 and the sheet metal part 31 and avoid interference between the nail post 11 and the sheet metal part 31 to produce abnormal noise.

[0050] Combination Figure 3 and Figure 7 As shown, in some embodiments, the nail post 11 has a column portion 111 for insertion into the mounting hole 311. The outer contour of the cross-section of the column portion 111 has different radial dimensions at at least two locations. In a first state, the location with the largest radial dimension of the outer contour of the cross-section of the column portion 111 is mutually restrained by the sheet metal part 31. By designing the shape of the column portion 111, at least two locations with different radial dimensions are created. This allows the distance between the column portion 111 and the wall of the mounting hole 311 to change with the rotation of the column portion 111 relative to the base 12, satisfying the adjustment requirements of the gap between the column portion 111 and the sheet metal part 31. This also helps to reduce the design difficulty and manufacturing cost of the nail post 11.

[0051] In the embodiment shown in the accompanying drawings of this application, taking the outer contour of the cross-section of the column portion 111 as approximately elliptical as an example, the radial dimensions of the column portion 111 vary at all points, thereby allowing the shortest distance between the column portion 111 and the wall of the mounting hole 311 to continuously change with the rotation of the column portion 111 relative to the base 12, facilitating the adjustment of the gap between the column portion 111 and the sheet metal part 31.

[0052] In some embodiments, the column portion 111 is provided with an operating structure 1111, which cooperates with an operating tool to drive the nail post 11 to rotate relative to the base 12. In some embodiments, the operating structure 1111 is an operating groove that extends radially through the column portion 111, and the extension direction of the operating structure 1111 can correspond to the position with the smallest radial dimension of the column portion 111, so as to avoid the setting of the operating structure 1111 affecting the mutual limiting between the column portion 111 and the sheet metal part 31. When the operating structure 1111 is an operating groove, the operating structure 1111 is used for the insertion of an operating tool to drive the nail post 11 to rotate relative to the base 12. For example, when the column portion 111 is inserted into the mounting hole 311, an operating tool such as a screwdriver can be inserted into the operating structure 1111 to manually drive the nail post 11 to rotate relative to the base 12, making the operation more labor-saving and improving the convenience of operation. In other embodiments, the operating structure 1111 may also be a protrusion on the column portion 111, for embedding into the groove structure of the operating tool so that the operating tool can drive the nail column 11 to rotate. The operating structure 1111 may also have other applicable configurations, which can be configured according to the operating tool and rotation requirements, as long as it can cooperate with the operating tool to drive the nail column 11 to rotate.

[0053] Please see Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments, the base 12 is provided with a mating groove 124, and the nail post 11 includes a column portion 111 and a mating portion 112 connected to each other. The column portion 111 is used to insert into the mounting hole 311, and the mating portion 112 is rotatably disposed in the mating groove 124. Figure 10 As shown, in some embodiments, the base 12 includes a first plate portion 121 and a second plate portion 122 that are opposite to and spaced apart from each other. A mating groove 124 is provided between the first plate portion 121 and the second plate portion 122. For example, the base 12 also includes a side plate portion 123 connected to the first plate portion 121 and the second plate portion 122. The first plate portion 121, the second plate portion 122, and the side plate portion 123 together form the mating groove 124. The nail post 11 also includes a plate body portion 113 connected to the post body portion 111 and spaced apart from the mating portion 112. The first plate portion 121 and the second plate portion 122 limit the mating portion 112 on opposite sides of the mating portion 112 to confine the mating portion 112 within the mating groove 124. The plate portion 113 limits the second plate portion 122 on the side opposite to the mating portion 112, which helps to improve the structural reliability of the positioning assembly 10 and the stability of the nail post 11 rotating relative to the base 12.

[0054] Combination Figure 4 and Figure 11As shown, the outer periphery of the mating part 112 is provided with at least one first limiting plane 1121, and the inner periphery sidewall of the mating groove 124 is provided with at least one second limiting plane 125. In the second state, the first limiting plane 1121 and the second limiting plane 125 are opposite to each other and mutually limit each other, so that the nail post 11 can be maintained in the second state, avoiding interference between the nail post 11 and the sheet metal part 31 and the abnormal noise.

[0055] The number of the first limiting plane 1121 and the second limiting plane 125 is unlimited, and can be set according to the limiting requirements between the nail post 11 and the base 12. Figure 11 In the illustrated embodiment, the mating part 112 is provided with three first limiting planes 1121 as an example. The three first limiting planes 1121 are arranged at intervals in the circumferential direction of the mating part 112. The inner circumferential sidewall of the mating groove 124 is provided with three second limiting planes 125. In the second state, the three first limiting planes 1121 and the three second limiting planes 125 correspond to each other and limit each other.

[0056] Combination Figure 3 and Figure 12 As shown, when the column portion 111 is inserted into the mounting hole 311, in the first state, the first limiting plane 1121 is offset from the second limiting plane 125, and there is no mutual limiting relationship between the mating portion 112 and the base 12. The column portion 111 is mutually limited with the sheet metal part 31 within the mounting hole 311 to achieve relative fixation between the glass assembly 20 and the sheet metal part 31. After the adhesive between the glass 21 and the sheet metal part 31 is cured, the nail column 11 is driven to rotate relative to the base 12 by an angle of 30°, 60°, or 90° until the first limiting plane 1121 and the second limiting plane 125 are opposite and mutually limited, so that the nail column 11 switches to the second state and remains in the second state, canceling the mutual limiting between the nail column 11 and the sheet metal part 31.

[0057] In the second state, the distance between the first limiting plane 1121 and the second limiting plane 125 can be less than or equal to 0.6 mm. The distances between each of the first limiting planes 1121 and the second limiting planes 125 can be equal or unequal, as long as the mutual limiting requirements between the mating part 112 and the base 12 are met, so that the nail post 11 can be maintained in the second state. For example, in some embodiments, in the second state, the distances between the three first limiting planes 1121 and the corresponding second limiting planes 125 are 0.5 mm, 0.56 mm, and 0.46 mm, respectively.

[0058] In some embodiments, in the second state, the first limiting plane 1121 and the second limiting plane 125 are in clearance fit. That is, in the second state, the first limiting plane 1121 and the second limiting plane 125 are not in an abutting limiting relationship, and there is a gap between the first limiting plane 1121 and the second limiting plane 125. This helps to increase the range of motion between the nail post 11 and the base 12. While limiting each other through the first limiting plane 1121 and the second limiting plane 125, the risk of mutual interference during the relative rotation of the nail post 11 and the base 12 can be avoided, making the rotation of the nail post 11 relative to the base 12 smoother.

[0059] Further, refer to Figure 13 As shown, in some embodiments, a third limiting surface 1122 is provided on the outer periphery of the mating part 112. At least a portion of the third limiting surface 1122 protrudes radially outward relative to the first limiting plane 1121. The third limiting surface 1122 is used to abut against the inner peripheral sidewall of the mating groove 124 to prevent the mating part 112 from continuing to rotate relative to the base 12. In some embodiments, the angle of rotation of the nail post 11 from the first state to the point where the third limiting surface 1122 abuts against the inner peripheral sidewall of the mating groove 124 is greater than the angle of rotation of the nail post 11 from the first state to the second state. That is, when the nail post 11 rotates from the first state relative to the base 12 to the second state, the nail post 11 continues to rotate relative to the base 12 in the same direction (e.g., clockwise) by a certain angle until the third limiting surface 1122 abuts against the inner peripheral sidewall of the mating groove 124. Under the limiting action of the third limiting surface 1122, the nail post 11 cannot continue to rotate clockwise relative to the base 12. Therefore, the third limiting surface 1122 can prevent the pin 11 from continuing to rotate and deviating excessively from the second state, so that the pin 11 can be kept in a state where it does not interfere with the limiting of the sheet metal part 31. The third limiting surface 1122 can be an arc-shaped surface, for example, the corner portion of the mating part 112 protrudes radially outward to form the third limiting surface 1122.

[0060] Combination Figure 3 and Figure 4 As shown, in some embodiments, after the nail post 11 rotates 30° clockwise relative to the base 12 from the first state to the second state, the first limiting plane 1121 and the second limiting plane 125 mutually limit each other. After the nail post 11 rotates 36° clockwise relative to the base 12 from the first state, the third limiting surface 1122 abuts against the inner peripheral sidewall of the mating groove 124, and the nail post 11 can no longer continue to rotate clockwise relative to the base 12. Figure 3 and Figure 5As shown, in some other embodiments, after the nail post 11 rotates 60° clockwise relative to the base 12 from the first state, it switches to the second state. After the nail post 11 rotates 66° clockwise relative to the base 12 from the first state, the third limiting surface 1122 abuts against the inner peripheral sidewall of the mating groove 124, and the nail post 11 can no longer continue to rotate clockwise relative to the base 12. Figure 3 and Figure 6 As shown, in some other embodiments, after the nail post 11 rotates 90° clockwise relative to the base 12 from the first state, it switches to the second state. After the nail post 11 rotates 96° clockwise relative to the base 12 from the first state, the third limiting surface 1122 abuts against the inner peripheral sidewall of the mating groove 124. The shape and relative position of the first limiting plane 1121, the second limiting plane 125, and the third limiting surface 1122 can be designed with reference to the angle of the nail post 11 relative to the base 12 in different states, and are not limited in this application.

[0061] Please see Figure 14 As shown, in some embodiments, the nail post 11 further includes a first limiting portion 114 connected to the outer periphery of the plate body portion 113, and the base 12 further includes a second limiting portion 126 disposed on the side of the second plate portion 122 facing away from the mating portion 112 and located on the outer periphery of the plate body portion 113. During the process of the nail post 11 switching from the first state to the second state, the first limiting portion 114 passes through the second limiting portion 126. In the second limiting state, the first limiting portion 114 and the second limiting portion 126 abut and limit each other. For example, the outer surface of the first limiting portion 114 and the inner surface of the second limiting portion 126 (the surface of the second limiting portion 126 facing the plate body portion 113) are arc-shaped guide surfaces with matching shapes. During the transition of the nail post 11 from the first state to the second state, when the nail post 11 rotates relative to the base 12 until the first limiting part 114 and the second limiting part 126 come into contact, the outer surface of the first limiting part 114 and the inner surface of the second limiting part 126 can slide together to provide guidance for the first limiting part 114, allowing it to pass smoothly through the second limiting part 126. After the first limiting part 114 passes the second limiting part 126, the end face of the first limiting part 114 abuts against the end face of the second limiting part 126 to prevent the nail post 11 from rotating in the opposite direction relative to the base 12, i.e., to prevent the nail post 11 from switching from the second state to the first state.

[0062] Thus, when the nail post 11 rotates relative to the base 12 from the first state to the second state, the first limiting part 114 and the second limiting part 126 abut against each other and limit the nail post 11, preventing the nail post 11 from rotating in the opposite direction relative to the base 12, avoiding the nail post 11 from switching from the second state to the first state, so that the nail post 11 can be kept in a state that does not interfere with the sheet metal part 31, avoiding interference between the nail post 11 and the sheet metal part 31 and the abnormal noise, and improving the structural reliability of the positioning assembly 10.

[0063] Understandably, in the second state, the first limiting plane 1121 and the second limiting plane 125 are not in abutting limiting relationship; instead, they are in clearance fit, allowing the stud 11 to rotate relative to the base 12. Based on this, a third limiting surface 1122 and a first limiting portion 114 are provided. The third limiting surface 1122 can limit the stud 11, preventing it from moving excessively away from the second state. The cooperation between the first limiting portion 114 and the second limiting portion 126 prevents the stud 11 from moving closer to the first state and switching back to the first state. Therefore, the third limiting surface 1122 and the first limiting portion 114 can limit the stud 11, restricting its maximum travel in opposite directions in the circumferential direction in the second state, thereby maintaining the stud 11 at a distance from the sheet metal part 31.

[0064] Please see again. Figure 1 and Figure 2 As shown, in some embodiments, the positioning component 10 further includes an adhesive structure 13, which is adhered to the side of the base 12 facing away from the nail post 11 and is used to adhere the base 12 to the glass 21. The adhesive structure 13 includes, but is not limited to, double-sided tape or liquid adhesive. In some embodiments, the materials of the nail post 11 and the base 12 include, but are not limited to, self-lubricating materials such as polyoxymethylene (POM), which can prevent abnormal noises when the nail post 11 and the base 12 rotate relative to each other.

[0065] Based on the glass assembly 20 and the vehicle described in any of the above embodiments, this application also provides a method for installing the glass assembly 20 onto the sheet metal part 31 of the vehicle. The installation method includes the following steps:

[0066] Adhesive is applied to the glass 21 of the glass assembly 20;

[0067] The glass 21 is placed on the sheet metal part 31, so that the nail post 11 is inserted into the mounting hole 311 of the sheet metal part 31 and mutually limited with the sheet metal part 31 to position the glass 21 and fix the glass 21 relative to the sheet metal part 31. The nail post 11 is in the first state.

[0068] After the adhesive between the glass 21 and the sheet metal 31 has cured to fix the glass 21 and the sheet metal 31 together, the nail post 11 is driven to rotate relative to the base 12 until the nail post 11 and the sheet metal 31 are spaced apart, thereby canceling the mutual restraint between the nail post 11 and the sheet metal 31, allowing the nail post 11 to switch to the second state. The nail post 11 is maintained in the second state by the setting of the first limiting plane 1121 and the second limiting plane 125. The setting of the third limiting surface 1122 and / or the first limiting part 114 can limit the nail post 11 in the second state, preventing the nail post 11 from deviating too much from the second state and interfering with the sheet metal 31.

[0069] The above-mentioned glass assembly 20 installation method allows the nail post 11 to not only position the glass 21 during the installation of the glass assembly 20, facilitating the connection between the glass 21 and the sheet metal part 31, but also to eliminate the mutual limiting between the nail post 11 and the sheet metal part 31 after the glass 21 and the sheet metal part 31 are fixed, thus avoiding interference between the nail post 11 and the sheet metal part 31 and the resulting abnormal noise.

[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
