[0020] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] The fastener 100 according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0022] Reference Figures 1-6 As shown, the fastener 100 according to an embodiment of this application may include: a screw 10 and a screw head 20. The fastener 100 may be a flanged stud.

[0023] Specifically, the screw head 20 is connected to one end of the screw rod 10 along its length. The outer peripheral wall of the screw rod 10 is provided with threads, which can be connected to the connecting structure or nut to meet the connection and fixing requirements of the fastener 100.

[0024] Furthermore, the thickness of the screw head 20 is greater than or equal to 10mm, meaning the thickness of the screw head 20 is T1 and satisfies T1≥10mm. Within this size range, the screw head 20 can be relatively thick, matching the thickness of the sound and heat insulation component 40, thus enabling installation and matching with the sound and heat insulation component 40, which has certain thickness requirements. Moreover, it meets the structural strength and rigidity requirements of the screw head 20, and the thicker screw head 20 can better distribute stress, avoiding problems such as deformation or damage to the screw head 20 due to localized stress concentration, ensuring the reliability of the fastener 100. For example, in some specific embodiments, the thickness of the screw head 20 can be 10mm, 15mm, 20mm, 25mm, 30mm, etc.

[0025] According to the embodiments of this application, the fastener 100 has a thread on the outer peripheral wall of the screw 10, and the screw head 20 is connected to one end of the screw 10 in the length direction. The thickness of the screw head 20 is greater than or equal to 10mm, and the thickness of the screw head 20 is adapted to the thickness of the sound insulation and heat insulation component 40, so that it can be installed and matched with the sound insulation and heat insulation component 40 with a certain thickness requirement. Moreover, while meeting the connection and fixing requirements of the fastener 100, it can ensure the structural strength and rigidity of the screw head 20, avoid problems such as deformation or damage of the screw head 20 due to local stress concentration, and ensure the reliability of the fastener 100.

[0026] In some embodiments of this application, such as Figure 4 As shown, the diameter of the screw head 20 is d1, and the diameter of the screw 10 is d2. d1 and d2 satisfy: d1 / d2=2-2.5, which allows the contact area between the end face of the screw head 20 near the screw 10 and the connecting structure (e.g., mounting bracket 50) to be larger, for example, the contact area is greater than 3mm², which can ensure the fixing reliability. Moreover, since the screw head 20 is thicker and heavier, increasing the contact area between the end face of the screw head 20 near the screw 10 and the connecting structure can improve the fastening force of the fastener 100, ensuring the reliability of the fastener 100 in use.

[0027] According to some embodiments of this application, such as Figures 2-5 As shown, an annular boss 21 is provided on the end face of the screw head 20 away from the screw rod 10. The annular boss 21 extends along the circumferential direction of the screw head 20, which can increase the structural strength of the screw head 20. The annular boss 21 can also increase the contact area with the connector 30, ensuring the reliability of the fixation and meeting different usage requirements.

[0028] In some embodiments, such as Figure 1 As shown, the annular boss 21 is welded to the connector 30 (e.g., the front wall panel) to meet the connection requirements between the fastener 100 and the connector 30. The annular boss 21 can increase the melting contact area between the end face of the screw head 20 away from the screw 10 and the connector 30, ensuring connection reliability.

[0029] In the embodiments of this application, the specific structure of the fastener 100 can be set according to the actual situation.

[0030] In some embodiments, the screw 10 and the screw head 20 can be a single piece, which simplifies the manufacturing of the fastener 100, provides high connection strength between the screw 10 and the screw head 20, and reduces assembly steps, thereby improving production efficiency and reducing production costs.

[0031] In some embodiments, the screw head 20 includes a body and an extension. The body is connected to one end of the screw 10 along its length. The extension is sleeved on the body. The height of the extension along the length of the screw 10 is greater than or equal to 10 mm, which can meet the thickness requirements of the screw head 20, ensure the structural strength and rigidity of the screw head 20, improve the reliability of the fastener 100, and the fastener 100 has a simple structure and is easy to process and manufacture.

[0032] In addition, the welded connection between the body and the extension ensures the reliability of the connection and helps to improve the structural strength of the screw head 20; or, the detachable connection between the body and the extension facilitates the replacement of the body and the extension, and can be set according to actual conditions to meet different usage requirements.

[0033] According to some embodiments of this application, the fastener can be a welded flange stud, which can achieve the required connection, and the process is simple, low in cost, and has a small amount of deformation, thus meeting different usage requirements.

[0034] The sound insulation and heat insulation component installation structure 200 according to an embodiment of this application includes a connector 30, a sound insulation and heat insulation component 40, a mounting bracket 50, and a fastener 100 according to an embodiment of this application.

[0035] Specifically, such as Figure 1 As shown, the sound insulation and heat insulation component 40 is located on one side of the connector 30 in the thickness direction, and the sound insulation and heat insulation component 40 is provided with a first opening 41. The mounting bracket 50 is located on the side of the sound insulation and heat insulation component 40 away from the connector 30, and the mounting bracket 50 is provided with a second opening 51. The second opening 51 is opposite to the first opening 41. At least a portion of the screw head 20 is located in the first opening 41, and the screw 10 passes through the second opening 51. The end face of the screw head 20 away from the screw 10 is connected to the connector 30.

[0036] Therefore, by connecting the screw head 20 to the connector 30 and the screw rod 10 passing through the connecting bracket, the mounting bracket 50 and the connector 30 can be connected and fixed, meeting the required connection requirements. Furthermore, the sound and heat insulation component 40 is located between the connector 30 and the mounting bracket 50, providing both heat and sound insulation. For example, the sound and heat insulation component 40 can isolate engine noise and heat, meeting the required usage requirements. For instance, the sound and heat insulation component 40 can be a sound and heat insulation pad.

[0037] The inventors of this application have discovered that when components are mounted on connectors 30 (e.g., front panel) via mounting brackets 50, in order to ensure noise, vibration, and harshness (NVH) performance, the sound insulation and heat insulation component 40 needs to ensure a certain thickness while minimizing the size of its openings. Since the screw head thickness of fasteners in related technologies is relatively low, for example, about 2mm, a sound insulation and heat insulation component 40 of this thickness cannot be formed. It is necessary to make large holes in the sound insulation and heat insulation component 40 to completely avoid the mounting brackets 50, but this can easily lead to a deterioration in NVH performance.

[0038] Therefore, in the embodiments of this application, by having a screw head 20 thickness greater than or equal to 10 mm and at least a portion of the screw head 20 located within the first opening 41, the screw head 20 can be made thicker, which facilitates matching with the sound insulation and heat insulation component 40, which has thickness requirements. The sound insulation and heat insulation component 40 can be assembled with the connector 30 and the mounting bracket 50 by only opening a smaller hole, ensuring NVH performance while guaranteeing connection, and reducing production costs.

[0039] In some embodiments, the sound insulation and heat insulation component mounting structure 200 includes a plurality of fasteners 100, the sound insulation and heat insulation component 40 is provided with a plurality of spaced first openings 41, and the mounting bracket 50 is provided with a plurality of spaced second openings 51. The plurality of first openings 41 and the plurality of second openings 51 are arranged opposite to each other. By having the plurality of fasteners 100 pass through the plurality of first openings 41 and second openings 51 respectively, the connection between the connector 30 and the mounting bracket 50 at multiple different positions can be ensured, thus ensuring a reliable connection between the connector 30 and the mounting bracket 50.

[0040] Since the fastener 100 according to the embodiments of this application has the above-mentioned beneficial technical effects, the sound insulation and heat insulation component installation structure 200 according to the embodiments of this application has threads on the outer peripheral wall of the screw 10, and the screw head 20 is connected to one end of the screw 10 in the length direction. The thickness of the screw head 20 is greater than or equal to 10mm, and the thickness of the screw head 20 is adapted to the thickness of the sound insulation and heat insulation component 40, so that it can be installed and matched with the sound insulation and heat insulation component 40 with a certain thickness requirement. Moreover, while meeting the connection and fixing requirements of the fastener 100, it can ensure the structural strength and rigidity of the screw head 20, avoid problems such as deformation or damage of the screw head 20 due to local stress concentration, and ensure the reliability of the fastener 100.

[0041] In some embodiments of this application, such as Figure 1 As shown, the thickness of the screw head 20 is greater than the thickness of the sound insulation and heat insulation component 40, which allows the end of the screw head 20 near the screw rod 10 to protrude from the sound insulation and heat insulation component 40. This creates a gap between the mounting bracket 50 and the sound insulation and heat insulation component 40, which avoids problems such as loss of nut preload caused by the interaction force generated by the mounting bracket 50 and the sound insulation and heat insulation component 40. This ensures that the fastener 100 is reliably connected to the connector 30 and the mounting bracket 50.

[0042] In some embodiments, the difference between the thickness of the screw head 20 and the thickness of the sound insulation and heat insulation component 40 is greater than or equal to 3 mm, ensuring that the end of the screw head 20 near the screw rod 10 protrudes from the sound insulation and heat insulation component 40, thus creating a gap between the mounting bracket 50 and the sound insulation and heat insulation component 40. This effectively prevents the mounting bracket 50 from abutting against the sound insulation and heat insulation component 40 and prevents loss of nut preload. For example, in some specific embodiments, the difference between the thickness of the screw head 20 and the thickness of the sound insulation and heat insulation component 40 can be 3 mm, 5 mm, 8 mm, 10 mm, 12 mm, 15 mm, etc.

[0043] According to some embodiments of this application, such as Figure 1 As shown, the diameter of the first opening 41 is larger than the diameter of the screw head 20, which makes it easier to insert the screw head 20 into the first opening 41, making installation more convenient and allowing the screw head 20 to move within the first opening 41. This avoids interference and other problems during installation, ensures installation reliability, and helps improve assembly efficiency.

[0044] In some embodiments, the difference between the diameter of the first opening 41 and the diameter of the screw head 20 is greater than or equal to 3 mm. This ensures that the screw is more easily installed through the first opening 41 and that the screw head 20 can move within the first opening 41, avoiding interference and other problems during installation and ensuring installation reliability. For example, in some specific embodiments, the difference between the diameter of the first opening 41 and the diameter of the screw head 20 can be 3 mm, 5 mm, 8 mm, 10 mm, 12 mm, 15 mm, etc.

[0045] In some embodiments of this application, the upper end of the screw head 20 is fitted with the wall of the first opening 41, which allows the screw head 20 to abut against the sound insulation and heat insulation component 40, preventing the sound insulation and heat insulation component 40 from naturally sagging due to gravity, avoiding problems such as displacement of the sound insulation and heat insulation component 40, effectively limiting the position of the sound insulation and heat insulation component 40, and ensuring the reliable sound insulation and heat insulation effect of the sound insulation and heat insulation component 40.

[0046] The vehicle according to an embodiment of this application includes a sound insulation and heat insulation component mounting structure 200 according to an embodiment of this application. Since the fastener 100 according to an embodiment of this application has the aforementioned beneficial technical effects, the sound insulation and heat insulation component mounting structure 200 according to an embodiment of this application, by having threads on the outer peripheral wall of the screw 10, and the screw head 20 connected to one end of the screw 10 in the length direction, the thickness of the screw head 20 is greater than or equal to 10mm, and the thickness of the screw head 20 is adapted to the thickness of the sound insulation and heat insulation component 40, thereby enabling it to be installed and matched with the sound insulation and heat insulation component 40 having certain thickness requirements; furthermore, while fulfilling the connection and fixing requirements of the fastener 100, it ensures the structural strength and rigidity of the screw head 20, avoiding problems such as deformation or damage of the screw head 20 due to local stress concentration, and ensuring the reliability of the fastener 100 in use.
