Description

Technical Field

[0001] The present invention relates to the technical field of automotive roof luggage boxes, and particularly to a roof box lock structure and a roof box. Background Art

[0002] The luggage box for the roof is used to increase the capacity of automotive luggage items and is attached to the top of the car. With the improvement of living standards, people's requirements for the luggage box for the roof are also getting higher and higher. In the existing roof box locks, due to the relatively long size of the roof box, a main lock and at least one sub-lock linked to the main lock are usually distributed and arranged on one side in the width direction. When the main lock is unlocked, other latches are simultaneously unlocked, so as to realize the opening of the luggage box lid. However, in actual use, users often ignore whether the sub-lock is also locked during the process of closing the lid, resulting in the risk that the lid may be opened during the driving of the car. On the other hand, the existing roof box locks are usually locked only on one side, which is inconvenient in use. Summary of the Invention

[0003] The purpose of the present invention is to provide a roof box lock structure and a roof box to solve the problems raised in the background art and overcome the deficiencies of the prior art.

[0004] To solve the above technical problems, the present invention is realized through the following technical solutions: A roof box lock structure includes a roof box and a locking mechanism. The roof box includes a lid and a base. The base is fixed on the roof of the car. It is characterized in that: the locking mechanisms are arranged on both the front side and the rear side of the roof box. The locking mechanism includes an outer latch, a linkage rod, and two or more latch assemblies. The outer latch includes a handle, a rotating buckle, and a rotating shaft connecting piece. The latch assembly includes an upper cover hook, a base hinge seat, and a locking buckle. The rotating shaft connecting piece is linked and connected with the locking buckle through the linkage rod. The handle is provided with a lock cylinder mounting seat. The lock cylinder mounting seat is provided with a rotating buckle connection structure, so that the handle and the rotating buckle rotate synchronously. The rotating shaft connecting piece is provided with a linkage sleeve. The linkage rod passes through the linkage sleeve. A rotating driving block is radially arranged on the outer wall of the linkage sleeve. The rotating driving block extends into the first driving cavity of the rotating buckle. When the rotating buckle rotates, the displacement of the first driving cavity changes, thereby pulling the rotating driving block, driving the linkage sleeve to drive the linkage rod to rotate. The locking buckle rotates synchronously with the linkage rod, thereby changing the unhooking / hooking state between the locking buckle and the upper cover hook.

[0005] The lock cylinder mounting seat and the rotating buckle are connected by a mortise and tenon structure.

[0006] A lock core is arranged in the lock cylinder mounting seat. The lock core is connected with a lock rotating connecting piece. A limit hook is installed at the tail end of the lock rotating connecting piece. The limit hook has an interference plate end, and the interference plate end is used to prevent the anti-rotation block of the rotating shaft connecting piece from rotating towards the handle side.

[0007] The limit hook is provided with a cross-shaped hole, the tail end of the lock rotation connecting piece is a cross-shaped column adapted to be connected with the cross-shaped hole, and the cross-shaped column is provided with a retaining spring groove on the side wall.

[0008] A limiting lock tongue is arranged in the lock core mounting seat, and the limiting lock tongue is provided with a latch protrusion. The lock core mounting seat is provided with a first notch for avoiding the passage of the latch protrusion. The handle is installed on the outer side of the lock core cover, and a latch socket is arranged in the lock core cover. The latch protrusion can be inserted into the latch socket through the first notch.

[0009] The lock rotating connecting piece is connected to the lock core through an eccentric sleeve, a strip through groove is arranged in the middle of the position-limiting lock tongue, and the eccentric sleeve moves in the strip through groove so that the lock latch protrusion can extend into or out of the latch socket.

[0010] The locking bolt assembly also includes an ejection slider and an ejection spring. The ejection slider moves in the sliding groove of the box seat hinge seat. One end of the ejection spring presses the bottom of the ejection slider. The upper cover hook is fixedly installed on the inner wall of the box cover. When the constraint of the locking buckle on the upper cover hook is released, the ejection slider pushes the upper cover hook upward to open the box cover.

[0011] The box seat hinge is fixedly mounted on the inner wall of the box seat, and a torsion spring is arranged between the box seat hinge and the locking buckle.

[0012] A first through-axis hole is arranged at the lower part of the box seat hinge seat, and a second through-axis hole is arranged at the lower part of the locking buckle, and the cross section of the second through-axis hole is adapted to the cross section of the linkage rod, and the upper part of the locking buckle is provided with a U-shaped arm, and a locking rod is installed at the top of the U-shaped arm; the sliding groove of the box seat hinge seat is formed by closing the two side plates and the rear plate, and the two side plates are provided with U-shaped limiting ribs facing each other so that the top opening and the front upper opening width of the sliding groove are smaller than the groove cavity width, and the ejection slider comprises a pushing plate, a limiting block, and a spring seat, the width of the pushing plate is smaller than the top opening of the sliding groove, and the width of the limiting block is larger than the top opening of the sliding groove, and a core-pulling process through hole is arranged on the back plate of the box seat hinge seat corresponding to the 7-shaped limiting rib, and a Π-shaped convex cavity is arranged around the sliding groove, so that when the locking buckle is flipped toward the Π-shaped convex cavity, the upper cover hook is separated from the locking rod of the locking buckle.

[0013] A roof box comprises the above-mentioned roof box lock structure.

[0014] The present invention has the following beneficial effects:

[0015] 1. The present invention has a simple and compact structure and is more reliable to use.

[0016] 2. When the rotating buckle of the outer latch rotates, the displacement of the first driving cavity changes, thereby pulling the rotating drive block, driving the linkage sleeve to drive the linkage rod to rotate, and the locking buckle of the bolt assembly rotates synchronously with the linkage rod, so that the upper cover hook disengages, and the box cover is opened. When the box cover is pressed down, the upper cover hook is hooked to the locking buckle, the linkage rod rotates reversely, and the handle returns to its original position. At this time, the lock core is rotated to the locked state, and the roof box is safely locked. The present invention realizes the synchronous linkage locking and unlocking of the locking mechanism through the linkage rod. When one side is unlocked, the other side can act as a pivot axis. When the box cover is flipped, the upper cover hook rotates around the locking rod. When the locking mechanisms on both sides are opened, the box cover can be removed, and this design is very convenient to use.

[0017] 3. The locking mechanism of the present invention has a good locking effect. The method of locking at the front and rear ends is more reliable. In addition, by having an interference plate end on the limit hook, the anti-rotation block of the rotating shaft connecting piece can be prevented from rotating towards the handle side, making the performance of the lock more firm and stable.
