Description

Technical Field

[0001] The invention relates to the technical field of buckles, in particular to a light hole locking buckle assembly. Background Art

[0002] In the field of automobile manufacturing and metal mounting plate connection, snap-on connection is popular because of its convenience and reliability. However, when it comes to snap-on connection of smooth holes (i.e. mounting holes with smooth inner walls and no threads), traditional connectors face severe challenges. The core problem is that the smooth inner hole wall makes the connection node single, resulting in poor fixing effect, which is easy to loosen or even fall off during vehicle operation, seriously affecting the stability and accuracy of the connection.

[0003] Specifically, in the traditional clamping parts, the gap between the holes is difficult to eliminate, which often causes the connection to deflect or loosen. At the same time, in order to ensure a stable connection, a large insertion force is often required, which not only increases the difficulty of installation, but also may cause damage to the components. In order to prevent the connection from falling off, the extraction force is required to be large enough, which further increases the complexity of the connection method and the requirements for component strength.

[0004] Although various improvement schemes have been proposed in the prior art, they are often difficult to be widely used due to their complex structure, cumbersome operation and high cost. Therefore, for light hole connection, a new type of clamping component and its connection method are urgently needed to overcome the inherent defects of the traditional method.

[0005] For this reason, we propose a light hole locking buckle assembly. Summary of the invention

[0006] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a light hole locking buckle assembly, which has multiple clamping mechanisms, optimized structural design, increased extraction force and other methods, which significantly improves the connection effect between the buckle body and the installation light hole. The support part of the plug-in component and the clamping joint of the clamping component work together to achieve a stable and reliable clamping connection.

[0007] The technical solution adopted by the present invention is as follows:

[0008] A light hole locking buckle assembly, comprising:

[0009] The plug-in component has a columnar structure and can be plugged into the installation light hole opened on the installation plate and is interference-connected with the installation light hole;

[0010] The clamping component is made of metal and is clamped and fixed on the plug-in component. When the buckle body is pulled out, it is clamped on the inner wall of the mounting hole to increase the pulling force.

[0011] The suction cup is on the same plane as the mounting plate and is used to be adsorbed on the side wall of the mounting plate after the plug-in component is inserted into the mounting light hole to increase the mounting force.

[0012] Furthermore, the plug-in component includes a plug-in column and a plug-in connector. The plug-in connector is located at the bottom of the plug-in column, and its end face is rounded and the side is closed to facilitate docking and installation of the light hole and to eliminate airflow.

[0013] Furthermore, the plug-in component also includes a support portion, which is located on the side wall of the plug-in column close to one end of the suction cup. There are at least two support portions, which are equidistantly distributed in a ring shape. The support portions extend radially outward and are interference-connected with the mounting light hole.

[0014] Furthermore, the plug-in component also includes a clamping part and a clamping block. The clamping part is an installation groove opened on the support part, which is used to provide an installation space for the clamping component; the clamping block is connected to both sides of the clamping part, is in the shape of a triangular prism, and facilitates the insertion and locking of the clamping component.

[0015] Furthermore, the clamping component includes a clamping sleeve, which is U-shaped and covers the clamping part of the plug-in component. The clamping sleeve is provided with a clamping interface corresponding to the clamping block of the plug-in component to achieve clamping fit.

[0016] Furthermore, the clamping component includes at least two clamping joints, and the ends of the clamping joints are connected with triangular spikes.

[0017] Furthermore, when the number of the card connectors is set to two, the two card connectors both adopt the structure of card connector one, and the two card connectors one are symmetrically distributed on both sides of the card connector sleeve. When the snap body is pulled out, the two card connectors one can be snapped onto the inner wall of the mounting light hole.

[0018] Furthermore, when the number of the clamping connectors is set to three, the clamping component also includes a second clamping connector, which is located on the same side as the two first clamping connectors and is smaller in size to increase the clamping force.

[0019] Furthermore, a bending portion is provided on one side of the clamping joint of the clamping component close to the clamping sleeve, and the bending portion contracts toward the plug-in column when the clamping joint moves into the installation light hole, and provides an elastic force toward the installation light hole.

[0020] Furthermore, an exhaust hole is provided on the end face of the suction cup opposite to the installation light hole, and a one-way valve for one-way exhaust to the outside is provided in the exhaust hole to quickly squeeze out excess air when the plug-in component is inserted, and cooperate with the sealing effect of the suction cup to make the installation light hole in a slightly negative pressure state.

[0021] The beneficial effects of the present invention are as follows:

[0022] The present invention has a compact and reasonable structure and is easy to operate. Through multiple clamping mechanisms, optimized structural design, and increased pull-out force, the connection effect between the clip body and the installation light hole is significantly improved. Under the joint action of the support part of the plug-in component and the clamping joint of the clamping component, a stable and reliable clamping is achieved; the circular end face and side closing design of the plug-in joint, as well as the annular equidistant distribution and extension design of the support part, reduce the resistance during insertion and improve the convenience of installation; the metal material of the clamping component, the number and layout of the clamping joint, and the addition of spikes significantly increase the pull-out force and ensure the long-term stability of the connection. At the same time, the adsorption effect of the suction cup and the slightly negative pressure state of the exhaust hole also provide additional guarantees for the stability of the connection. In summary, the light hole locking clip in this embodiment has the characteristics of excellent connection effect, small insertion force, large pull-out force, etc., and is suitable for application scenarios such as automobiles that require high stability and safety.

[0023] At the same time, the present invention also has the following advantages:

[0024] The multiple snap-fit ​​mechanism significantly improves the connection stability. The light hole locking buckle in this embodiment constructs a multiple snap-fit ​​mechanism through the interference fit between the support part of the plug-in component and the installation light hole, and the tight snap fit between the snap joint of the snap-fit ​​component and the inner wall of the installation light hole. This design not only increases the contact area between the buckle body and the installation light hole, but also significantly improves the stability and reliability of the connection through friction, elastic force, and nail embedding. Even in the strong vibration environment caused by high-speed driving of the vehicle, the risk of falling off can be effectively avoided, ensuring the overall safety and reliability of the car.

[0025] The optimized structural design reduces the insertion force and improves the convenience of installation. The plug connector of the plug-in component adopts a circular end face and a side closing design, which makes the plug-in process smoother and can automatically adjust the alignment with the installation light hole, reducing installation errors. At the same time, the annular equidistant distribution and extension design of the support part, as well as the elastic contraction characteristics of the curved part of the clamping part, work together to reduce the resistance during insertion, making the installation process easier and more convenient. This design not only improves the installation efficiency, but also reduces the skill requirements for the installer, which is conducive to widespread promotion and application.

[0026] Increase the pull-out force and ensure a long-lasting and stable connection. The metal material selection of the clamping parts, the number and layout design of the clamping joints, and the addition of spikes have significantly increased the pull-out force of the clamp body. Especially when pulling out, the curved part of the clamping joint will be tightly embedded in the inner wall of the installation hole, and the spikes will further increase the friction, making the pull-out process require greater external force. This design effectively prevents the clamp from accidentally falling off due to vibration or external force, ensuring a long-lasting and stable connection. At the same time, the adsorption effect of the suction cup and the slightly negative pressure state of the exhaust hole also provide additional protection for the stability of the connection.

[0037] The specific implementation of the present invention is described below in conjunction with the accompanying drawings.

[0038] like Figure 1-Figure 4 As shown, this embodiment discloses a light hole locking buckle assembly, which is connected to the mounting light hole 30 of the automobile mounting plate 20 and provides installation space for other components (such as wiring harnesses). In this embodiment, the buckle body 10 adopts a specially designed structure, which can closely fit the inner wall of the mounting light hole 30, and can maintain a stable clamping state even in a strong vibration environment generated by high-speed driving of the vehicle, effectively avoiding the risk of falling off, thereby improving the overall safety and reliability of the vehicle.

[0039] The buckle body 10 in this embodiment includes a plug-in component 100, a clamping component 200, a suction cup 300 and a docking component 400, wherein the plug-in component 100, the suction cup 300 and the docking component 400 are formed by an advanced integrated injection molding process, ensuring seamless connection between the components and the strength of the overall structure. This design not only improves the durability of the product, but also simplifies the production process and reduces the manufacturing cost.

[0040] The plug-in component 100 is made of plastic or rubber, which not only has good flexibility and wear resistance, but also can absorb vibration and reduce noise to a certain extent.

[0041] like Figure 2 As shown, the plug-in column 101 in this embodiment is the main structure of the plug-in component 100, and its design fully considers the balance between mechanical performance and installation convenience. The end face of the plug connector 102 is rounded and the side is closed (that is, the diameter of the plug connector 102 decreases toward the outside), which not only makes the plug-in process smoother, but also can automatically adjust the alignment with the installation light hole 30 during the installation process, reducing installation errors. At the same time, when the plug connector 102 is inserted into the installation light hole 30, the air in the hole can be quickly discharged, thereby further enhancing the tightness of the clamping.

[0042] In actual use, after the clamping component 200 is fixed to the plug-in component 100 , as long as the extended range of the clamping component 200 is larger than the diameter of the installation light hole 30 , the installation and fastening effect can be achieved.

[0043] However, in order to improve the fastening effect, the diameter of the plug connector 102 and the inner diameter of the mounting light hole 30 need to be adapted and connected, and the spacing value between the two after installation should be less than 30% of the diameter of the mounting light hole 30. That is, when the spacing value between the two after installation is greater than 30% of the diameter of the mounting light hole 30, it is necessary to replace the buckle with a more suitable size to improve the subsequent clamping effect.

[0044] In this embodiment, the mounting light hole 30 is usually circular, and in special cases it is elliptical or other special-shaped structures, and snap connection can also be achieved through the snap assembly in this embodiment.

[0045] The number of the support parts 103 in this embodiment is at least two, and at least two support parts 103 are distributed equidistantly in an annular manner on the side wall of the plug-in column 101, ensuring the stable support of the buckle body 10 in the installation light hole 30. The design of the support part 103 extending radially outward not only increases the contact area with the inner wall of the installation light hole 30, but also generates sufficient friction through the interference connection, so that the buckle body 10 can be firmly fixed on the mounting plate and remain motionless even under strong vibration or impact. In addition, the extension design of the support part 103 also prevents the buckle body 10 from shaking, ensuring the stability and reliability of the connection. This design is particularly important in applications such as automobiles that require high stability and safety. It can effectively avoid problems such as noise, wear and even falling off caused by shaking of the connecting parts, thereby improving the safety and service life of the entire system.

[0046] In this embodiment, the number of the supporting parts 103 is two, and the two supporting parts 103 are located on the same plane and are fixedly connected with the outer wall of the plug-in column 101 and the mounting light hole 30 .

[0047] like Figure 2 As shown, the clamping part 104 in this embodiment serves as a connecting bridge between the plug-in component 100 and the clamping component 200, and its design is directly related to the performance and reliability of the entire locking buckle. The opening of the mounting groove not only provides sufficient installation space for the clamping component 200, but also ensures the smooth progress of the clamping process. The design of the clamping block 105 is even more ingenious. Its triangular prism structure not only increases the contact area with the clamping component 200, but also realizes the easy insertion and firm locking of the clamping component 200 through its special protruding height design. When the clamping component 200 is inserted into the clamping part 104, the inclined surface of the clamping block 105 will guide the clamping component 200 to enter smoothly, and after reaching the predetermined position, the clamping component 200 is tightly locked by elastic deformation to prevent it from falling off.

[0048] like Figure 2 and Figure 3 As shown, the clamping component 200 is made of metal, which can improve the elastic force and the clamping force. The specific metal should be selected according to the size of the plugging and unplugging force, and the hardness of the metal should be selected mainly. If the metal hardness of the clamping component 200 is greater than the hardness of the mounting plate 20, the clamping effect is better and the pull-out force is greater, but scratches will be left in the mounting light hole 30.

[0049] If the selected metal hardness is lower than the hardness of the mounting plate 20, scratches will not be easily generated, but the extraction force will be smaller. Therefore, the material of the clamping component 200 will be determined according to the material of the mounting plate 20, and the rigidity also needs to be adjusted. If the rigidity is too large, the clamping force will be greater, and the extraction force will also be greater. If the rigidity is small, the clamping force will be smaller, and the extraction force will be relatively small.

[0050] Preferably, the material of the clamping component 200 is the same as that of the mounting plate 20. This choice ensures that it has sufficient strength and rigidity when subjected to external forces, thereby effectively resisting the stress during extraction. The clamping component 200 is not only clamped and fixed to the plug-in component 100 to form a stable connection as a whole, but also when the buckle body 10 is pulled out, its unique clamping design can be tightly clamped to the inner wall of the mounting light hole 30, significantly increasing the extraction force of the buckle body 10. This design effectively prevents the buckle from accidentally falling off under vibration or external force by increasing the resistance during extraction, thereby improving the safety and reliability of the connection. The material selection of the clamping component 200 also takes into account its good corrosion resistance and wear resistance, which can maintain stable performance in long-term use and extend the service life of the buckle.

[0051] Specifically, Figure 2 and Figure 3As shown, the clamping component 200 in this embodiment includes an integrally formed clamping sleeve 201, a bent portion 202, a clamping joint 203 and a clamping interface 204. This integrated design simplifies the installation process, reduces the gap between components, and improves the overall stability. The clamping sleeve 201 is U-shaped and covers the clamping portion 104. Its shape design is not only convenient for close cooperation with the clamping portion 104 of the plug-in component 100, but also realizes the precise clamping cooperation between the clamping block 105 and the clamping interface 204 by providing two clamping interfaces 204 corresponding to the clamping block 105. This clamping method not only ensures the firm connection between the clamping component 200 and the plug-in component 100 in the radial direction, but also effectively constrains the clamping component 200 in the axial direction by limiting the inner diameter of the installation light hole 30, thereby ensuring the stability and reliability of the entire buckle body 10 after installation. The U-shaped design of the card sleeve 201 also facilitates fine adjustment during installation to ensure the best fit between the card component 200 and the plug component 100. At the same time, the opening position and size of the card interface 204 are carefully designed to ensure a close fit with the card block 105 to avoid loosening or falling off during use.

[0052] The upper end of the clamp sleeve 201 in this embodiment is connected with at least two clamp joints, and this design increases the contact area between the clamp component 200 and the inner wall of the installation light hole 30, and improves the stability of the clamping and the extraction force. When there are two clamp joints, the clamp joints adopt the structure of clamp joint 1 203, which are symmetrically arranged on both sides of the clamp sleeve 201, and can evenly disperse the stress during extraction, and prevent the buckle body 10 from being damaged due to uneven force.

[0053] like Figure 3 As shown, in another embodiment, the number of the card connectors is increased to three, including two symmetrically arranged card connectors 1 203 and one card connector 2 203 ′ located on the same side of the two card connectors.

[0054] Although the size of the second clamping joint 203' is relatively small in this design, it is because the first clamping joint 203 and the second clamping joint 203' are both arranged on the same clamping sleeve 201, and the clamping sleeve 201 is formed by cutting and bending a whole plate. Therefore, after the two clamping joints 1 203 are processed and formed into a staple, the remaining position can only form the second clamping joint 203' with a smaller size. Although the second clamping joint 203' is relatively small in size, it is located in different directions of the two clamping joints 1 203, so it can form a more comprehensive clamping effect and further improve the clamping force. The number and layout of the clamping joints can be flexibly adjusted according to the specific installation requirements and the size of the installation light hole 30 to meet the use requirements in different scenarios. At the same time, the shape and size of the first clamping joint 203 and the second clamping joint 203' are also optimized to ensure that they can be tightly clamped to the inner wall of the installation light hole 30 to provide sufficient extraction force.

[0055] In this embodiment, the card connector is provided with a curved portion 202 on one side close to the card sleeve 201. This design cleverly utilizes the elastic properties of the material. When the card connector moves into the installation light hole 30, the curved portion 202 will shrink in the direction of the plug-in column 101, so it will not cause a large insertion force when inserted, and at the same time, it will generate an elastic force toward the installation light hole 30. This design not only avoids the shaking of the buckle body 10 during the installation process, but also enables the card connector to be more tightly embedded in the inner wall of the installation light hole 30 when it is pulled out, thereby significantly improving the pull-out force and enhancing the stability of the installation. The design of the curved portion 202 also takes into account the deformation problem of the card connector 200 during the installation process. By reasonably controlling the bending degree and elastic modulus of the curved portion 202, it can be ensured that the card connector 200 can be smoothly inserted into the installation light hole 30 during the installation process, and can provide sufficient resistance when it is pulled out to prevent accidental falling off.

[0056] The triangular spikes connected to the card connector in this embodiment further enhance the card connection effect. This spike design can increase the friction between the card connector and the inner wall of the mounting light hole 30, making the card connection more secure. At the same time, the triangular shape also ensures that the spikes can be better embedded in the inner wall of the mounting light hole 30 when being pulled out, providing a greater pull-out force. The design of the spikes also takes into account the problem of damage to the inner wall of the mounting light hole 30. By reasonably controlling the size and shape of the spikes, it can be ensured that while providing sufficient pull-out force, no serious damage or scratches are caused to the inner wall of the mounting light hole 30.

[0057] like Figure 1 and Figure 2 As shown, the suction cup 300 in this embodiment is on the same plane as the mounting plate 20. This design enables the suction cup 300 to fit tightly against the side wall of the mounting plate 20, thereby further improving the installation force. Since the mounting plate 20 is usually made of metal and has a smooth surface, the suction cup 300 can utilize its adsorption characteristics to firmly adsorb on the mounting plate 20 after the plug-in component 100 is inserted into the mounting light hole 30, thereby preventing the buckle body 10 from shaking or falling off. The material and size of the suction cup 300 have also been carefully designed to ensure that it has good adsorption performance and durability. At the same time, the contact surface between the suction cup 300 and the mounting plate 20 has also been specially treated to improve its adsorption effect and stability.

[0058] The exhaust hole 301 provided on the end surface of the suction cup 300 opposite to the installation light hole 30 and the one-way valve provided therein provide an effective exhaust channel for the installation light hole 30 of the blind hole. When the plug-in component 100 is inserted, the exhaust hole 301 can quickly squeeze out the excess air to avoid the formation of air pressure resistance, making the plug-in process smoother and reducing the insertion resistance. At the same time, the excess air is absorbed by the adsorption device, and the sealing effect of the suction cup 300 is combined to make the installation light hole 30 in a slightly negative pressure state, thereby further improving the clamping effect.

[0059] The docking component 400 is connected to the suction cup 300. This design is not only convenient for connecting and installing with other component harnesses through cable ties, but also effectively closes the exhaust hole 301. The position of the docking component 400 corresponds to the exhaust hole 301. When the docking component 400 is connected to other components, the exhaust hole 301 can be tightly closed to avoid slight air leakage in the exhaust hole 301, thereby maintaining a slight negative pressure state in the installation light hole 30 and ensuring a long-lasting and stable clamping effect.

[0060] like Figure 1-Figure 4 As shown, the working principle in this embodiment is as follows:

[0061] First, the clamping sleeve 201 covers the clamping part 104 and is precisely clamped with the clamping block 105 through the clamping interface 204, ensuring a firm connection between the clamping component 200 and the plug-in component 100 in the radial direction. At the same time, the number and layout of the clamping connectors are flexibly adjusted according to the installation requirements and the size of the installation light hole 30 to ensure that they can be tightly clamped to the inner wall of the installation light hole 30 and provide sufficient extraction force.

[0062] Then align the clip body 10 with the installation light hole 30 for insertion. Since the diameter of the plug-in column 101 is adapted to the inner diameter of the installation light hole 30, the smoothness and tightness of the insertion process are ensured. The end face of the plug connector 102 is circular and the side is closed, which is not only convenient for insertion into the installation light hole 30, but also can automatically adjust the alignment during the installation process to reduce installation errors. At the same time, the support parts 103 are distributed in an annular and equidistant manner on the side walls of the plug-in column 101, and sufficient friction is generated with the inner wall of the installation light hole 30 through interference connection, ensuring that the clip body 10 can be firmly fixed on the mounting plate and can remain motionless even under strong vibration or impact. At the same time, when installing in a blind hole, the plug-in column 101 can squeeze out excess air in the blind hole installation light hole 30 during the downward insertion process;

[0063] The suction cup 300 and the mounting plate 20 are on the same plane and can fit tightly against the side wall of the mounting plate 20, further improving the mounting force. The exhaust hole 301 and the one-way valve thereon provide an effective exhaust channel for the installation light hole 30 of the blind hole, ensuring a smooth plugging process, and the installation light hole 30 is in a slightly negative pressure state through the adsorption device, further improving the clamping effect.

[0064] Finally, the docking component 400 facilitates connection and installation with other component harnesses through cable ties.

[0065] The present invention has a compact and reasonable structure and is easy to operate. Through multiple clamping mechanisms, optimized structural design, and increased extraction force, the connection effect between the buckle body 10 and the installation light hole 30 is significantly improved. Under the joint action of the support part 103 of the plug-in component 100 and the clamping joint of the clamping component 200, a stable and reliable clamping is achieved; the circular end face and side closing design of the plug-in joint 102, and the annular equidistant distribution and extension design of the support part 103 reduce the resistance during insertion and improve the convenience of installation; the metal material of the clamping component 200, the number and layout of the clamping joints, and the addition of spikes significantly increase the extraction force and ensure the long-term stability of the connection. At the same time, the adsorption effect of the suction cup 300 and the slightly negative pressure state of the exhaust hole 301 also provide additional guarantees for the stability of the connection. In summary, the light hole locking buckle in this embodiment has the characteristics of excellent connection effect, small insertion force, large extraction force, etc., and is suitable for application scenarios such as automobiles that require high stability and safety.
