[0044] Please see Figure 1 , Figure 2 and Figure 3 As shown, where Figure 1 This is a three-dimensional schematic diagram of the fastener structure 100 according to the first embodiment of the present utility model;
[0045] Figure 2 yes Figure 1 A cross-sectional view of the fastener structure 100 in its separated state; and Figure 3 yes Figure 1 A cross-sectional view of the fastener structure 100 in its assembled state. In the first embodiment, the fastener structure 100 includes a first fastener 110 and a second fastener 120. The fastener structure 100 can be applied to a battery box for fastening the battery box cover to the battery box body; however, the scope of this utility model is not limited thereto.
[0046] The first fastener 110 includes a first fastener body 111, at least one first engaging portion 112, and at least one second engaging portion 113. The first fastener body 111 has an insertion hole 1111. The first engaging portion 112 is disposed on the inner wall surface of the first fastener body 111 (unless otherwise labeled). The second engaging portion 113 is also disposed on the inner wall surface of the first fastener body 111 and is connected to one end of the first engaging portion 112. In detail, in the first embodiment, the number of the first engaging portion 112 and the second engaging portion 113 is one. In the actual manufacturing process, the number of the first engaging portion 112 and the second engaging portion 113 can be increased according to the requirements, and each of the first engaging portion 112 and each of the second engaging portion 113 can have the same or similar structural configuration. Therefore, the content of this utility model is not limited to the content disclosed in the first embodiment.
[0047] from Figure 2 It can be seen that the first engaging portion 112 is a recessed portion and the second engaging portion 113 is a convex portion. Both are disposed on the inner wall surface of the first fastener body 111 and form a continuous engaging area on the first fastener body 111. The second engaging portion 113 is located near the opening of the insertion hole 1111, while the first engaging portion 112 is disposed deeper in the inner wall surface and further away from the opening of the insertion hole 1111 than the second engaging portion 113.
[0048] The second fastener 120 is detachably assembled to the first fastener 110 and includes a second fastener body 121, at least one first engaging portion 122, and at least one second engaging portion 123. The second fastener body 121 has an elastic structure, allowing for detachable assembly without damage. The first engaging portion 122 is disposed on the outer wall surface of the second fastener body 121 (not otherwise labeled), and its position corresponds to the first engaging portion 112 of the first fastener 110. The second engaging portion 123 is also disposed on the outer wall surface of the second fastener body 121 and connects to one end of the first engaging portion 122, and its position corresponds to the second engaging portion 113 of the first fastener 110. Specifically, in the first embodiment, the number of both the first engaging portion 122 and the second engaging portion 123 is one, corresponding to the number of the first engaging portions 112 and the second engaging portions 113, respectively. In actual manufacturing, the number of the first engaging portion 122 and the second engaging portion 123 can be increased as needed, and each of the first engaging portion 122 and each of the second engaging portion 123 can have the same or similar structural configuration. Therefore, the content of this utility model is not limited to the content disclosed in the first embodiment.
[0049] from Figure 2 It can be seen that the first engaging portion 122 is a protrusion, while the second engaging portion 123 is a recess. Both are provided on the outer wall surface of the second fastener body 121, and form a continuous engaging area on the second fastener body 121.
[0050] When the second fastener body 121 is inserted into the insertion hole 1111 of the first fastener body 111, the first engaging portion 112 engages with the first engaging portion 122, and the second engaging portion 113 engages with the second engaging portion 123. Specifically, during the engagement process, the first step is that the protruding first engaging portion 122 first contacts the concave first engaging portion 112 and begins to engage. This process provides initial fixation, ensuring the initial connection between the fastener structures 100. As the second fastener body 121 continues to be inserted, the second step is that the protruding second engaging portion 113 further engages with the concave second engaging portion 123, forming a two-stage engagement structure.
[0051] The first stage of engagement provides stable initial fixation, preventing the fastener structure 100 from loosening or misaligning during initial insertion. The second stage of engagement further strengthens the fixation, resulting in greater stability and resistance to loosening. This two-stage engagement structure not only effectively prevents the fastener structure 100 from loosening under external force or vibration but also ensures long-term reliability, making it particularly suitable for high-load or frequently used applications.
[0052] In the first embodiment, the second fastener body 121 further includes an elastic section 1211 and a fixed section 1212. The elastic section 1211 is pressed by the user and has a first engaging portion 122 and a second engaging portion 123. The fixed section 1212 connects to the elastic section 1211. A space S exists between the elastic section 1211 and the fixed section 1212. Specifically, the elastic section 1211 and the fixed section 1212 present a U-shaped structure. Compared with the solid structure in the prior art, the present invention not only reduces the amount of material used, thereby effectively saving costs, but also allows the user to easily insert or remove the second fastener body 121 without excessive force or special tools, thus further improving the convenience of assembly and disassembly.
[0053] Please refer to the following: Figure 2A horizontal line L defines the space between the elastic section 1211 and the fixed section 1212. The angle between the elastic section 1211 and the horizontal line L is the first angle θ1, and the angle between the fixed section 1212 and the horizontal line L is the second angle θ2. The first angle θ1 is between 7 and 8 degrees, while the second angle θ2 is between 2 and 3 degrees. In the first embodiment, the first angle θ1 is 7.5 degrees and the second angle θ2 is 2.5 degrees. This invention is not limited to these angles and can be adjusted according to specific needs. By setting the first angle θ1 and the second angle θ2, the insertion of the second fastener body 121 is made smoother, and the potential for jamming or resistance during assembly is effectively reduced. Due to the precise setting of the angles, the user can easily achieve precise alignment without applying excessive force during insertion, reducing the risk of damage caused by improper operation or excessive pressure. It also ensures the long-lasting and stable stability of the fastener structure 100 after each engagement, preventing loosening due to prolonged use or vibration. Furthermore, the angled design makes disassembly of the fastener structure 100 equally simple; users can easily disassemble it without additional tools, making it particularly suitable for applications requiring frequent assembly or disassembly. This not only improves work efficiency but also reduces the risk of operational errors, making it more suitable for various environments requiring quick and easy assembly.
[0054] Please continue reading. Figure 3 The first engaging portion 112 has an engaging abutment surface 1121. The first engaging portion 122 has an engaging abutment surface 1221. The second engaging portion 113 has a first abutment apex 1131 and a second abutment apex 1132. The second engaging portion 123 has a bottom abutment surface 1231 and a wall abutment surface 1232. When the second fastener body 121 is inserted into the insertion hole 1111 of the first fastener body 111, the engaging abutment surface 1121 contacts and abuts against the engaging abutment surface 1221. At the same time, the first abutment apex 1131 abuts against the bottom abutment surface 1231, and the second abutment apex 1132 abuts against the wall abutment surface 1232. In this way, the fastener structure 100 achieves stable positioning and limiting functions under the action of two abutment methods (face-to-face abutment and face-to-point abutment), effectively improving the stability of the structure and its resistance to external interference. Face-to-face contact provides a wider contact area, ensuring the stability of the overall structure; while point-to-point contact concentrates the force precisely on key parts, effectively preventing relative displacement, thereby ensuring the stability of the interlocking structure.
[0055] Please refer to the following: Figure 1 , 4 As shown, Figure 4 This is a perspective view of the fastener structure 100a according to the second embodiment of the present utility model. Compared to Figure 1In the first embodiment of the fastener structure 100, in the second embodiment, the number of the first engaging portion 112, the second engaging portion (not shown separately), the first engaging portion 122, and the second engaging portion 123 are all two. This increase in the number of the first engaging portion 112, the second engaging portion, the first engaging portion 122, and the second engaging portion 123 helps to further improve the stability and load-bearing capacity of the fastener structure 100a. It reduces potential damage caused by excessive pressure on a single engaging point, thereby improving the overall durability and tensile strength of the structure.
[0056] It should be noted that the other components and structural configurations of the buckle structure 100a in the second embodiment are the same as or similar to those of the buckle structure 100 in the first embodiment, and will not be described again here.
[0057] In summary, the fastener structure of this utility model has the following advantages: First, the two-stage locking mechanism achieves a stable locking effect, ensuring stability during each assembly process and effectively preventing loosening under high loads or external forces; second, the angled design makes the insertion process smoother, reduces resistance during assembly, reduces the force required by the user, and ensures the long-term stability of the fastener structure; third, by increasing the number of locking components, the burden on each locking point is distributed, improving the overall load-bearing capacity and tensile strength of the structure, enhancing the durability of the fastener structure, and making it suitable for various application scenarios that require frequent assembly or disassembly.
[0058] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the scope of the present invention. Any person skilled in the art may make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
