Description

[Technical Field]

[0001] This disclosure relates to a fastener structure. [Previous Technology]

[0002] Fasteners typically consist of two cooperating components that achieve fixation through an engaging structure. However, existing fasteners generally suffer from several defects that can affect their performance and reliability. For example, insufficient engaging strength may cause the fastener to fail under high loads or repeated use, failing to effectively maintain its fixing function. Furthermore, fasteners are prone to loosening under vibration or external forces, and cannot provide sufficient stability and safety in extreme environments.

[0003] Furthermore, the existing fasteners have a relatively complex structure, which makes them unable to achieve a cost advantage in mass production and may make them difficult to compete in the economy market. This is especially true for applications requiring high-frequency use, such as battery boxes, where the stability and durability of the fasteners are paramount. However, existing fasteners cannot maintain a stable engagement effect under frequent use, leading to frequent replacements or maintenance and increased repair costs. Therefore, how to simplify the structure, reduce costs, and simultaneously improve engagement strength and durability has become a pressing problem for the industry. [Summary of the Invention]

Therefore, the first component can also be referred to as the second component. Moreover, the combination of components / units / circuits in this document is not a combination that is generally known, conventional, or customary in this field. Whether the component / unit / circuit itself is customary cannot be used to determine whether its combination relationship is easily completed by someone with ordinary knowledge in the art.

[0017] Please refer to Figures 1, 2, and 3, wherein Figure 1 is a perspective view of the fastener structure 100 according to the first embodiment of this disclosure; Figure 2 is a cross-sectional view of the fastener structure 100 in the separated state of Figure 1; and Figure 3 is a cross-sectional view of the fastener structure 100 in the joined state of Figure 1. 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, but this disclosure is not limited thereto.

[0018] The first fastener 110 includes a first fastener body 111, at least one first snap-fit ​​portion 112, and at least one second snap-fit ​​portion 113. The first fastener body 111 has an insertion hole 1111. The first snap-fit ​​portion 112 is disposed on an inner wall surface of the first fastener body 111 (not otherwise labeled). The second snap-fit ​​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 snap-fit ​​portion 112. In detail, in the first embodiment, the number of the first snap-fit ​​portion 112 and the second snap-fit ​​portion 113 is one. In the actual manufacturing process, the number of the first snap-fit ​​portion 112 and the second snap-fit ​​portion 113 can be increased according to the requirements, and each of the first snap-fit ​​portion 112 and each of the second snap-fit ​​portion 113 can have the same or similar structural configuration. Therefore, the content of this disclosure is not limited to the content disclosed in the first embodiment.

[0019] As can be seen from Figure 2, the first engaging portion 112 is a recess, and the second engaging portion 113 is a protrusion. Both are disposed on the inner wall surface of the first fastener body 111, forming 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.

[0020] 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 an 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 disclosure is not limited to the content disclosed in the first embodiment.

[0021] As can be seen from Figure 2, 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.

[0022] 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.

[0023] The first stage of engagement provides stable initial fixation, preventing the fastener structure 100 from loosening or misaligning during initial insertion; while the second stage of engagement further strengthens the fixation, thereby achieving greater stability and resistance to loosening. The 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.

[0024] 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 a 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, this disclosure not only reduces the use of materials, 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, thereby further improving the convenience of assembly and disassembly.

[0025] Referring to Figure 2, a horizontal line L is defined 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 disclosure 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, not only is the insertion process of the second fastener body 121 smoother, but it also effectively reduces the possible jamming or resistance problems during assembly. Due to the precise setting of the angles, the user can easily achieve accurate docking 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.

[0026] Please refer to 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.

[0027] Please refer to Figures 1 and 4 together. Figure 4 is a perspective view of the fastener structure 100a according to the second embodiment of this disclosure. Compared with the fastener structure 100 of the first embodiment in Figure 1, 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. Therefore, the 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.

[0028] It must 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.

[0029] In summary, the fastener structure disclosed herein has the following advantages: First, through the two-stage locking mechanism, a stable locking effect is achieved, ensuring stability during each assembly process and effectively preventing loosening under high load or external force; Second, the angled setting 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.

[0030] Although the present disclosure has been disclosed above with reference to embodiments, it is not intended to limit the present disclosure. Anyone skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present disclosure. Therefore, the scope of protection of the present disclosure shall be determined by the appended claims. [Simplified Explanation of the Diagram]
