Abstract
Description
Technical Field
[0001] This utility model relates to the field of connection technology, specifically a decoupling structure for connecting front components, especially front and rear vehicle bodies, by means of decoupling. Background Technology
[0002] The hook used for connection is a common connecting component. The hook includes a mounting base with an open ring. The components to be connected have a connecting ring with a loop or rope. When part of the connecting ring engages with the open ring, a locking mechanism at the opening of the open ring locks it, forming a closed loop. The connecting ring or rope then engages within this closed loop, thus achieving a locking connection. To separate the connected components, simply unlock the mechanism and detach the connecting ring or rope from the open ring.
[0003] However, when the connecting ring and the hook are connected via a connecting ring, the connecting ring and the hook are generally interference fit. The connecting ring is prone to vibration due to the movement of the front and rear parts, which leads to poor connection stability. Utility Model Content
[0004] The main purpose of this utility model is to provide a disengagement mechanism to solve the problem that in the prior art, the connecting ring is prone to vibration within the disengagement mechanism during disengagement, which affects the service life of the connecting ring and the disengagement mechanism, and also easily causes vibration of the front components.
[0005] This utility model provides a release mechanism, including a mounting base with an upwardly extending and side-bent protrusion on the mounting base, forming an open ring with the protrusion and the mounting base; a locking element is provided at the opening of the open ring to open or close the opening; the mounting base has a mounting hole at a corresponding position on the open ring, and a telescopic buffer is provided on the back of the mounting hole; the telescopic buffer has a telescopic rod extending into the mounting hole, the telescopic rod abutting and inserting into the open ring, and abutting a connecting ring located inside the open ring.
[0006] Preferably, a mounting plate is provided on the back of the mounting hole, the mounting plate has a cross-section in the shape of a "Z", a gap is left between the middle of the mounting plate and the mounting seat, and the telescopic buffer is fixed on the mounting plate; the mounting plate is provided with a telescopic hole, and the telescopic rod extends from the telescopic hole to the mounting hole.
[0007] Preferably, the telescopic buffer is a hydraulic cylinder or a pneumatic cylinder.
[0008] Preferably, the end of the telescopic rod is provided with a clamping block, and the clamping block is provided with a groove that is adapted to the connecting ring.
[0009] Preferably, the telescopic rod bends toward the portion of the protrusion.
[0010] Preferably, the buffer telescopic component is a spring, and the spring abuts against the telescopic rod.
[0011] The unhooking method provided by this utility model has the following advantages compared with the prior art:
[0012] The aforementioned disengagement process involves inserting the connecting ring into the open ring of the disengagement mechanism, and then closing the opening of the open ring with a locking device to form a closed loop, thereby achieving the connection between the connecting ring and the disengagement mechanism. The mounting base has mounting holes. After the connecting ring segment is inserted into the closed ring, the telescopic rod of the telescopic buffer can extend through these mounting holes into the closed loop formed by the disengagement mechanism and abut against the connecting ring segment located within the closed loop. This causes both ends of the connecting ring to be clamped and compressed by the telescopic rod and the inner wall of the closed ring, preventing the connecting ring from vibrating or moving, thus improving the stability of the disengagement connection.

[0027] Example 1
[0028] This embodiment provides a release mechanism, which includes a mounting base 1. The mounting base 1 has an upwardly extending and side-bending protrusion 2. In this embodiment, the mounting base 1 is a flat plate, and the protrusion 2 is a protruding structure extending upward and then bending to one side on the surface of the flat plate. The mounting base 1 and the protrusion 2 can be integrally cast, forming an open ring. A locking element 3 is provided at the opening of the open ring, capable of opening or locking the opening. The locking element 3 can close the opening through operation. The locking element 3 can have one end rotatably connected to one end of the opening, and the other end fixed to the other end of the opening by a snap-fit or lock. Alternatively, it can seal the opening of the open ring using any existing method such as a pin. This release mechanism is generally used to connect front and rear vehicle bodies. One of the front and rear vehicle bodies is equipped with the release mechanism, and the other is equipped with a tow bar with a connecting ring. The connecting ring is engaged with the open ring of the release mechanism, and then the opening of the open ring is closed by the locking element 3, forming a closed loop, thus connecting the connecting ring and the release mechanism, and consequently connecting the front and rear vehicle bodies.
[0029] The mounting base 1 has a mounting hole 6 at the corresponding position of the open ring. A telescopic buffer is provided on the back of the mounting hole 6. The telescopic buffer has a telescopic rod 5 that extends into the mounting hole 6. The telescopic rod 5 is inserted into the open ring and abuts against the connecting ring located within the open ring. After the connecting ring segment is engaged with the closed ring, the telescopic rod 5 of the telescopic buffer can extend from the mounting hole 6 into the closed ring formed by the disengagement and abut against the connecting ring segment located within the closed ring. This causes both ends of the connecting ring to be clamped and squeezed by the telescopic rod 5 and the inner wall of the closed ring, preventing the connecting ring from vibrating and moving, thereby improving the stability of the disengagement connection.
[0030] Specifically, in this embodiment, a mounting plate 7 is provided on the back of the mounting hole 6. The mounting plate 7 has a Z-shaped cross-section, that is, the mounting plate 7 includes a vertical plate extending to one side of the plate surface. The outer end of the vertical plate extends outward along the plate surface direction to form a connecting plate. The mounting plate 7 is fixed to the mounting base 1 through the connecting plate. At this time, due to the setting of the vertical plate, the plate body of the mounting plate 7 can leave a gap with the mounting base 1. The telescopic buffer is fixed on the mounting plate 7. The mounting plate 7 is provided with a telescopic hole, and the telescopic rod 5 extends from the telescopic hole to the mounting hole 6.
[0031] Specifically, in this embodiment, the telescopic buffer is a hydraulic cylinder or a pneumatic cylinder 8, preferably a pneumatic cylinder 8. By setting the hydraulic cylinder or pneumatic cylinder 8, the buffering pressure of the telescopic buffer can be kept constant. When the connecting ring connected to the telescopic rod 5 is subjected to excessive impact force, the telescopic buffer can also buffer the impact force through the extension and retraction of the telescopic rod 5.
[0032] Specifically, in this embodiment, in order to adapt the telescopic rod 5 to the ring segment of the connecting ring, the end of the telescopic rod 5 is provided with a clamping block 4, and the clamping block 4 is provided with a groove that is adapted to the connecting ring.
[0033] Specifically, in this embodiment, the telescopic rod bends towards the portion of the protrusion. That is, the connecting ring is located on the upper part of the telescopic rod and below the bent portion of the protrusion, and is clamped and squeezed by the protrusion and the telescopic rod.
[0034] Specifically, the aforementioned buffer telescopic component is preferably a cylinder 8, but it can also be any existing structure that applies force to the telescopic rod 5, such as a spring, where the spring abuts against the telescopic rod 5.
[0035] Of course, the above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model and should be protected by the present utility model.
