Description

Technical Field

[0001] This utility model relates to the field of quick-release buckle technology, and more specifically, to a quick-release buckle and a vehicle attachment bracket. Background Technology

[0002] In existing technologies, to enhance the functional expandability of vehicles in scenarios such as outdoor camping, fieldwork, or leisure travel, various external expansion accessories, such as tents, projector screens, shower curtains, and mosquito nets, are typically installed directly or indirectly onto the vehicle body using quick-release clips. This type of quick-release connection structure allows for rapid assembly when needed and convenient disassembly when not in use, demonstrating excellent adaptability and flexibility.

[0003] However, vehicles generate continuous vibrations during normal driving, especially when driving on unpaved roads, where the vibration intensity is even greater. Conventional snap-on fasteners, due to their simple structure and limited locking reliability, are prone to loosening or even disengaging during driving vibrations, causing extension accessories to fall off unexpectedly. This not only affects the safety and stability of vehicle use but also limits the further application of quick-release structures in the automotive field.

[0004] Therefore, there is an urgent need to propose a quick-release buckle device with a more reliable structure that is less prone to disengagement under vibration, in order to meet the safe connection requirements of vehicles for external expansion accessories. Summary of the Invention

[0005] This invention aims to solve the problems of accidental unlocking, unreliable connection, and unstable structural fit of quick-release buckles in vibration environments. It proposes a quick-release buckle that achieves rapid locking and unlocking by driving the locking tongue through a sliding sleeve. The structure provides axial positioning and anti-torsion capabilities, significantly improving connection reliability and vibration resistance. It is suitable for the rapid attachment needs of vehicles and other vibration conditions.

[0006] This utility model embodiment also proposes a vehicle attachment bracket having the above-mentioned quick-release buckle.

[0007] To achieve the above objectives, this utility model provides a quick-release buckle, comprising: A connecting assembly includes a body, a sliding sleeve, a top cover, and a pair of locking tongues. The sliding sleeve is slidably fitted onto the body, the top cover is fixed to the upper part of the body and forms a columnar protrusion, and the locking tongue is slidably mounted on the body and located at the edge of the top cover. The locking tongue is configured to lock or unlock by the movement of the sliding sleeve relative to the body. The base assembly has a cylindrical groove that mates with the top cover. The inner wall of the cylindrical groove is provided with a locking groove, which engages with the locking tongue when the locking tongue is in the locked state.

[0008] In the aforementioned quick-release buckle structure, the linkage design between the sliding sleeve and the locking tongue allows the user to drive the locking tongue horizontally by pushing the sliding sleeve, thereby achieving quick locking and unlocking between the cylindrical protrusion on the top cover and the cylindrical groove on the base. The entire operation is simple and rapid. In the locked state, the locking tongue mechanically engages with the locking groove on the base, effectively preventing loosening or unlocking due to vehicle vibration, thus improving the reliability of the connection. Simultaneously, the cylindrical groove and the top cover form a mating structure. This structure not only ensures precise axial positioning but also achieves excellent anti-torsional capabilities through geometric interlocking, effectively preventing loosening due to rotational torque during use, further enhancing the stability and security of the quick-release connection.

[0009] According to one embodiment of this utility model, the inner wall of the sliding sleeve is provided with a first inclined surface, and the locking tongue has a second inclined surface. The first and second inclined surfaces cooperate to convert the vertical movement of the sliding sleeve into the horizontal movement of the locking tongue. This structure utilizes the inclined surface cooperation to realize the conversion of the movement direction, reducing the complexity of the mechanism and improving the smoothness and efficiency of unlocking and locking operations.

[0010] According to one embodiment of the present invention, the bottom of the latch is provided with a slider portion, and the second inclined surface is formed on the slider portion.

[0011] According to one embodiment of this utility model, a middle frame fixed to the main body is further included, the middle frame being located between the main body and the upper cover. The middle frame serves to limit and guide, further stabilizing the sliding trajectory of the locking tongue and improving the rigidity of the overall structure.

[0012] According to one embodiment of this utility model, the locking tongue is restricted to sliding within the space between the middle frame and the upper cover. By limiting the structural space, the sliding of the locking tongue is more controlled, preventing misalignment or displacement and ensuring locking accuracy.

[0013] According to one embodiment of this utility model, a sliding groove is provided at the bottom of the middle frame, and the slider part slides in conjunction with the sliding groove. The sliding groove further provides precise guidance for the slider, making the movement of the locking tongue smooth and reliable during the unlocking or locking process.

[0014] According to one embodiment of the present invention, the cross-sectional profile of the cylindrical groove is non-circular; and / or, a second spring is provided between the sliding sleeve and the main body, the second spring generating an elastic preload force to keep the sliding sleeve in the locked position. The non-cylindrical design enhances the anti-rotation capability of the assembly, while the elastic force provided by the second spring keeps the sliding sleeve in the locked position when not in operation, improving the anti-vibration and anti-dislodgement capability.

[0015] According to one embodiment of this utility model, a first shock-absorbing pad is provided on the surface of the upper cover; and / or, a second shock-absorbing pad is provided between the main body and the sliding sleeve. The shock-absorbing pad effectively buffers vibrations during vehicle operation, reduces wear between structures, and improves overall vibration resistance.

[0016] According to one embodiment of this utility model, a first spring is provided between each group of locking tongues. The first spring generates an elastic preload force that moves the locking tongue towards the locking groove. The preload force provided by the first spring ensures that the locking tongue automatically resets and remains locked during use, which helps to prevent the locking tongue from shifting or loosening due to vibration, and further improves security.

[0017] This utility model also provides a vehicle attachment bracket, which is installed on a vehicle via any of the quick-release clips described above. The vehicle attachment bracket connects to the vehicle body via these quick-release clips and can suspend various extension accessories, such as tents, projection screens, shower curtains, mosquito nets, etc., meeting the needs of vehicle expansion in multiple scenarios. It is easy to operate, has a reliable connection, and is suitable for various usage environments such as outdoor camping and leisure activities. Attached Figure Description

[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Example

[0033] like Figure 1-11As shown, this embodiment discloses a quick-release buckle, including a connecting component 10 and a base component 20. The connecting component 10 includes a main body 11, a sliding sleeve 12, a top cover 13, and a pair of locking tongues 15. The main body 11 is an integrally formed columnar structure. The sliding sleeve 12 has a cylindrical structure, with a pair of abutment portions 12a protruding from its inner wall, and a first inclined surface 12b on the inner end surface of the abutment portions 12a. The sliding sleeve 12 is slidably fitted onto the outside of the main body 11 and can slide up and down along the axial direction of the main body 11. The top cover 13 is installed on the upper part of the main body 11 and is fixedly connected to the main body 11. The top cover 13 protrudes upward from the upper end of the main body 11 to form a columnar protrusion, the length and width of which are smaller than the length and width of the main body 11. The locking tongues 15 are symmetrically arranged on both sides of the main body 11 and are slidably installed on the main body 11 in a horizontal direction. The front end of the locking tongue 15 is provided with a locking portion 15a that cooperates with the locking groove 23.

[0034] Furthermore, in this embodiment, the base assembly 20 is used for mounting on a vehicle, more specifically, fixedly mounted on the vehicle body or tailgate. Preferably, it is mounted on the inner surface of the tailgate. The base assembly 20 has two opposing ends. One end is provided with a positioning post 21, which engages with a positioning hole on the tailgate. The other end of the base assembly 20 is provided with a cylindrical groove 22. The two opposing inner walls of the cylindrical groove 22 are provided with locking grooves 23, and the locking portion 15a at the outer end of the locking tongue 15 engages with the locking groove 23.

[0035] Furthermore, combined Figure 2-8 As shown, the sliding sleeve 12 and the locking tongue 15 form a linkage structure. The inner wall of the sliding sleeve 12 is provided with a first inclined surface 12b, and the locking tongue 15 has a matching second inclined surface 15c. When the sliding sleeve 12 slides downward in the vertical direction, the first inclined surface 12b and the second inclined surface 15c come into contact with each other and slide, causing the locking tongue 15 to move outward in the horizontal direction, thereby opening or closing the locking tongue 15 and completing the locking or unlocking operation. This inclined surface linkage structure can convert vertical motion into horizontal motion, simplify the transmission structure, and improve the response sensitivity and smoothness of the mechanism.

[0036] Furthermore, combined Figure 9 As shown, the latch 15 has a slider portion 5b at its bottom, and the second inclined surface 15c is formed on the upper surface of the slider portion 5b. The slider portion 5b protrudes from the bottom surface of the latch 15.

[0037] Furthermore, combining Figure 7 As shown, the quick-release buckle also includes a middle frame 14 structure. The middle frame 14 is fixedly installed between the main body 11 and the upper cover 13. Its shape fits the outline of the main body 11. The upper end of the middle frame 14 is provided with a mounting groove 14a, and the locking tongue 15 is slidably installed in the mounting groove 14a.

[0038] Furthermore, combined Figure 5-6 As shown, the latch 15 is restricted to slide within the space between the middle frame 14 and the upper cover 13. The sliding range of the latch 15 is defined by the opening edge of the mounting groove 14a and the side wall of the upper cover 13, thereby ensuring that the latch 15 operates orderly in the horizontal direction. A sliding groove 14b is provided through the bottom of the middle frame 14, and the slider 5b forms a sliding fit with the sliding groove 14b. The slider passes through and extends out of the sliding groove 14b, and its second inclined surface 15c is located at the bottom of the middle frame 14 and contacts the first inclined surface 12b.

[0039] Furthermore, combining Figure 3 As shown, in this embodiment, the upper cover 13 and the middle frame 14 are fixed to the upper part of the main body 11 from top to bottom by fasteners 18. The fasteners 18 are countersunk bolts, the lower end of which passes through the upper cover 13 and is threaded to the hollow main body 11. The surface of the upper cover 13 is provided with a first shock-absorbing pad 19, which is bonded to the upper cover 13 and covers the upper end of the fasteners 18.

[0040] Furthermore, combined Figure 11 As shown, the base assembly 20 has a cylindrical groove 22 that matches the columnar protrusion of the upper cover 13. The cross-sectional profile of the cylindrical groove 22 is non-circular, such as polygonal, elliptical, or irregular geometric shape, which can form a geometric interlock after being inserted and fitted with the upper cover 13 to prevent torsion. In this embodiment, the cylindrical groove 22 is a square cylindrical groove 22, and the corresponding upper cover 13 is square. The inner wall of the cylindrical groove 22 has a locking groove 23, which may or may not penetrate the side wall of the cylindrical groove 22. Figure 2 As shown, the locking tongue 15 can be engaged in the locking groove 23 in the locked state to achieve mechanical fixation.

[0041] Furthermore, to ensure that the sliding sleeve 12 always remains in the locked position, a second spring 17 is provided between the sliding sleeve 12 and the main body 11. The second spring 17 is a compression spring, which is vertically arranged, with one end abutting against the inner wall of the sliding sleeve 12 and the other end abutting against the corresponding limiting surface of the main body 11. When the user does not apply force, the elastic force generated by the second spring 17 pushes the sliding sleeve 12 to the initial locked position, ensuring that the buckle is in the default locked state.

[0042] Furthermore, to improve the overall vibration resistance, a first damping pad 19 is provided on the surface of the upper cover 13, and a second damping pad 110 is provided between the main body 11 and the sliding sleeve 12. The damping pads can be made of materials such as rubber, silicone, or polyurethane foam, which can buffer impacts, reduce vibration transmission between structures, extend service life, and improve stability.

[0043] Furthermore, a first spring 16 is provided between each set of locking tongues 15. The first spring 16 is installed in the connecting groove between the two locking tongues 15. The first spring 16 is horizontally set, and its action direction makes the locking tongues 15 always move in a direction away from each other, that is, it makes the locking tongues 15 move towards the direction closer to the locking groove 23. Thus, after the user releases the sliding sleeve 12, the locking tongues 15 automatically return to the locking position, realizing the automatic locking function and avoiding the risk of loosening due to untimely operation.

[0044] Combination Figure 12 As shown, another embodiment discloses a vehicle attachment bracket, which is installed on the exterior of a vehicle via the aforementioned quick-release clips. The quick-release clips are compact and easy to install, allowing for rapid installation and removal without tools, and are compatible with various vehicle-mounted extension devices. The vehicle attachment bracket can hang accessories such as tents, projection screens, shower curtains, and mosquito nets, meeting the rapid deployment needs of vehicles in various scenarios such as camping, leisure, and temporary shelter, and possesses excellent expandability and adaptability.
