[0033] Reference below Figure 1-Figure 4 A fastening assembly 100 according to an embodiment of the present invention is described.

[0034] like Figure 1 and Figure 2 As shown, the fastening assembly 100 according to the embodiment of the utility model includes a mounting body 1 , a nut 2 and a bolt 3 .

[0035] Specifically, Figure 1 and Figure 2 As shown, combined Figure 4 The installation body 1 has an installation space 11, and at least one of the two axial ends of the installation space 11 is open, so that the installation body 1 has enough open installation space 11, which is convenient for assembly and connection with other parts. While ensuring the strength of the installation body 1 itself, it also saves the material of the installation body 1, thereby reducing the cost. The inner wall of the installation space 11 is provided with an anti-rotation rib 114, which is used to prevent the nut 2 from rotating. The nut 2 is arranged in the installation space, and the nut 2 has an anti-rotation part that cooperates with the anti-rotation rib 114. When tightening the bolt 3, a torque is generated to drive the nut 2 to rotate. The anti-rotation part cooperates with the anti-rotation rib 114 on the inner wall of the installation space 11, which can play a limiting and fixing role, and can prevent the nut 2 from rotating, which is convenient for the connection between the bolt 3 and the nut 2. Among them, the nut 2 is detachably connected to the installation body 1, with a compact structure, convenient loading and unloading, and simple operation. Further, the bolt 3 is connected to the nut 2, and the connecting member 5 is suitable for being located between the head of the bolt 3 and the installation body 1. The outer wall of the bolt 3 is provided with an external thread, and the nut 2 can be provided with an opening penetrating in the thickness direction and an internal thread on the inner wall of the opening, the internal thread matches the external thread, and the internal thread and the external thread are rotatably connected to realize the connection and installation between the bolt 3 and the nut 2.

[0036] For example, when two parts need to be connected, the nut 2 is first inserted into the mounting body 1 and the nut 2 and the mounting body 1 are placed on one side of the part 5 to be connected, and the bolt 3 is fixedly connected to the nut 2 in the mounting body 1 from the other side of the part 5 to be connected by rotating the internal thread and the external thread, so that the part 5 to be connected is located between the head of the bolt 3 and the mounting body 1 and is clamped and fixed. The structure is simple and compact, and a reliable and stable connection effect can be achieved. It is easy to disassemble and is convenient for installation, which not only realizes the connection function but also saves costs.

[0037] In addition, if Figure 1 and Figure 3 As shown, a plurality of support plates 13 are provided on the outer peripheral wall of the mounting body 1, and the plurality of support plates 13 are spaced apart along the circumferential direction of the mounting body 1. The support plates 13 are preferably triangular vertical plates, and one of the right-angled sides of the triangle is flush with the bottom surface of the mounting body 1, and the other right-angled side is in contact with and connected to the outer wall of the mounting body 1, thereby providing support force for the mounting body 1 and strengthening the structural strength and torsional strength of the mounting body 1, thereby avoiding deformation caused when the nut 2 is twisted and disassembled.

[0038] According to the fastening assembly 100 of the embodiment of the utility model, by connecting the bolt 3 with the nut 2 provided in the installation space 11 of the installation body 1, a detachable connection of the two components can be achieved, which has a simple and compact structure, low cost and convenient assembly and disassembly. The inner wall of the installation space 11 is provided with an anti-rotation rib 114, and the nut 2 is provided with an anti-rotation portion that cooperates with the anti-rotation rib 114, thereby playing a limiting and fixing role, preventing the nut 2 from rotating, and facilitating the connection and assembly of the bolt 3 and the nut 2.

[0039] It is easy to disassemble and facilitate installation, which not only realizes the connection function but also saves costs.

[0040] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, one side of the installation space 11 is opened to form a notch 111, so that the installation body 1 has enough open installation space 11, which is convenient for matching and connecting with the nut 2. Further, the notch 111 passes through the installation body 1 in the axial direction of the installation space 11, so that the nut 2 can be clamped in the installation body 1 through the axially penetrating notch 111, which facilitates installation and removal.

[0041] In some embodiments of the present invention, Figure 1 and Figure 3As shown, the peripheral wall of the installation space 11 has a limiting protrusion 112 extending along the circumferential direction of the installation space 11, which is used to limit the movement of the nut 2. In addition, along the axial direction of the nut 2, the nut 2 includes a body portion 21, a first limiting portion 22 and a second limiting portion 23. The body portion 21 is inserted into the limiting protrusion 112, and the first limiting portion 22 and the second limiting portion 23 are respectively connected to the two ends of the body portion 21 and are respectively located on both sides of the limiting protrusion 112. Figure 1 In the example shown, the nut 2 is preferably an annular member with a through hole in the middle, the main body 21 can be a cylinder and is inserted and installed in the limiting protrusion 112, and the first limiting portion 22 and the second limiting portion 23 provided at both ends of the nut 2 can limit the limiting protrusion 112 between the first limiting portion 22 and the second limiting portion 23, so that the main body 21 is maintained in the limiting protrusion 112, which plays a positioning role and ensures that the nut 2 does not fall off relative to the installation body 1.

[0042] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the inner walls of the limiting protrusion 112 on both sides of the notch 111 are provided with a plurality of limiting ribs 113 spaced apart along the circumferential direction of the limiting protrusion 112. Figure 3 In the example shown, the limiting rib 113 can be a hemispherical protrusion, which is located in the space between the limiting protrusion 112 and the main body 21 of the nut 2. While limiting the nut 2, it also reserves a certain amount of space for the nut 2 to move, so as to accommodate assembly errors of the bolt 3 and the nut 2 during installation, so that the limiting protrusion 112 and the nut 2 maintain a clearance fit, thereby increasing the limiting accuracy.

[0043] In some embodiments of the present invention, Figure 1 As shown, the second limiting portion 23 has two opposite limiting planes, and the two limiting planes are configured as the anti-rotation portion. The two opposite inner walls of the installation space 11 have anti-rotation ribs 114 that cooperate with the two limiting planes. The two limiting planes cooperate with the anti-rotation ribs 114 on the inner wall of the installation space 11 to prevent the nut 2 from rotating, which facilitates the connection between the bolt 3 and the nut 2. The structure is simple and easy to implement, and the processing cost is low. Figure 1 In the example shown, the projection of the second limiting portion 23 of the nut 2 on a plane perpendicular to the thickness direction is a square, that is, the second limiting portion 23 is a quadrangular prism. When the bolt 3 and the nut 2 are connected and fixed to generate torque, the two opposite side walls on the quadrangular prism can be abutted against the anti-rotation ribs 114 in the installation space 11, thereby limiting the torsional movement of the nut 2 during the tightening process and facilitating the connection between the bolt 3 and the nut 2.

[0044] In some embodiments of the present invention, Figure 1As shown, the mounting body 1 and the anti-rotation rib 114 are an integral part, and the anti-rotation rib 114 is molded and integrated with the mounting body 1, which provides a stable connection and helps to enhance the structural strength, while reducing the number of structural components of the fastening assembly 100, facilitating assembly and material management, thereby reducing costs.

[0045] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, a waterproof rib 12 extending along the circumferential direction of the installation body 1 is provided on the surface of the side of the installation body 1 facing the part to be connected 5. The waterproof rib 12 is suitable for abutting against the part to be connected 5, so that when the part to be connected 5 is tightened, the contact surface of the installation body 1 and the part to be connected 5 is at the position of the waterproof rib 12, which plays a positioning role, and prevents the bolt 3 from being screwed into the nut 2 insufficiently, which causes the connection of the part to be connected 5 to be loosened, thereby affecting the stability of the connection and the waterproof performance of the connection. For example, when it is necessary to connect and tighten two parts, the nut 2 and the installation body 1 are on one side of the part to be connected 5, and the bolt 3 passes through the mounting hole of the part to be connected 5 on the other side of the part to be connected 5 and is fixedly connected to the nut 2 in the installation body 1. During the tightening process, the distance between the head of the bolt 3 and the installation body 1 is gradually reduced. When one side of the part to be connected 5 abuts against the head of the bolt 3 and the other side abuts against the waterproof rib 12, the connection and fixation of the part to be connected 5 is completed. The structure is simple and compact, easy to install, and can ensure the connection stability of the part to be connected 5 and the waterproof effect of the connection.

[0046] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the mounting body 1 and the waterproof rib 12 are an integrated part. The waterproof rib 12 is molded and integrated with the mounting body 1, which provides a stable connection and helps to enhance the structural strength. At the same time, it reduces the number of structural components of the fastening assembly 100, facilitates assembly and material management, and thus reduces costs.

[0047] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the fastening assembly 100 also includes a sealing gasket 4, which is arranged on the side of the nut 2 facing the part 5 to be connected and is suitable for abutting against the part 5 to be connected. In the initial state, the height of the sealing gasket 4 is greater than the height of the waterproof rib 12. In the process of connecting and fastening the bolt 3 with the nut 2 in the installation body 1, as the distance between the head of the bolt 3 and the installation body 1 gradually decreases, one side of the part 5 to be connected first abuts against the sealing gasket 4. Since the sealing gasket 4 has the ability to deform, the bolt 3 can continue to be tightened. When the part 5 to be connected abuts against the waterproof rib 12, the sealing gasket 4 is in a compressed state and squeezed between the nut 2 and the part 5 to be connected, providing friction while achieving a waterproof effect.

[0048] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the sealing gasket 4 is bonded to the nut 2, which can improve the firmness of the connection. The connection method is simple and easy to assemble.

The mounting body 1 has a mounting space 11, and the axial ends of the mounting space 11 are open, so that the mounting body 1 has enough open mounting space 11, which is convenient for assembly and connection with other components. While ensuring the strength of the mounting body 1 itself, it also saves the material of the mounting body 1, thereby reducing the cost of vehicle parts. The inner wall of the mounting space 11 is provided with an anti-rotation rib 114, which is used to prevent the nut 2 from rotating. The nut 2 is arranged in the mounting space 11, and the nut 2 has an anti-rotation part that cooperates with the anti-rotation rib 114. When the bolt 3 is tightened, a torque is generated to drive the nut 2 to rotate.
