Description

Folding device docking buckle structure

This invention belongs to the technical field of folding connection. Specifically, it refers to a folding device docking buckle structure with a two-stage safety mechanism, which enables the relative hinges to be folded and locked quickly and conveniently. At the same time, it has the effect of double protection and synchronous automatic locking to avoid unlocking due to incorrect action, which can effectively ensure its safety in use.

According to the invention, the folding device can be used in many places where selective folding and buckling are required, such as portable means of transportation such as folding bicycles and scooters. The folding device is usually arranged on the vehicle body or handlebars. When the vehicle body or handlebars are folded and folded in sections after use, the volume thereof can be reduced to facilitate the rider to carry the vehicle outside.

The general folding device is usually used for a tube or frame designed as a two-stage mechanism, and a quick-release locking assembly is provided on the opposite side of the hinge point at the separation point for selective release of the folding. Common quick-release locking assemblies mostly adopt a cam mechanism, and both locking and unlocking require the user to perform manual segmented operations, which is time-consuming and labor-intensive, and brings inconvenience to the user. Furthermore, it is usually a single lock when locked, without a second layer of safety, and it is easy to loosen due to improper touch, causing danger during riding.

In short, since the design of the existing folding device is not perfect, there is a possibility that the folding device may be unlocked due to an incorrect action when docking the buckle, which seriously affects the safety of use. In addition, since the buckle does not have the function of automatic locking, it causes inconvenience in operation. Therefore, how to avoid the above-mentioned problems is a topic that the relevant industry is eager to improve, and it is also what this creation wants to explore.

Thereby, a folding device and a buckle structure with double safety and automatic locking function is constructed.

As for the actual operation of the folding device docking buckle structure of the present invention, as shown in the fourth figure, when the first and second hinges (10, 20) are normally docked and the segmented lock assembly (30) is used to lock a single body (100), the first and second hinges (10, 20) are docked with the first and second pivots (11, 21) as the axis, and the segmented lock assembly (30) pivoted on the second hinge (20) by the main shaft (31) is received in the first and second half openings of the first and second hinges (10, 20). In the receiving space (A) formed by the grooves (15, 25), the lock post (54) on the lock stop member (50) of the segmented lock assembly (30) is locked onto the lock rod (35) of the first half-open groove (15), and the limit slide buckle (45) of the pressure plate member (40) is locked onto the lock head (32) in the first half-open groove (15), so that the first and second hinges (10, 20) produce a locking and limiting effect, and at the same time, the pressure plate member (40) of the segmented lock assembly (30) can be prevented from sliding off at will, thereby forming a double safety effect.

When folding is required, as shown in the fifth, sixth and seventh figures, the anti-slip buckle (45) on the pressure plate (40) of the segmented lock assembly (30) is pushed forward through the push portion (450), so that the anti-slip buckle (45) can compress the resetting elastic member (46) to generate a preload for resetting backwards, and at the same time, the lock plate (47) of the anti-slip buckle (45) can be separated from the lock head (32) in the first half-open groove (15) of the first hinge (10). [As shown in FIG. 5], the pressing plate (40) is then turned outward [as shown in FIG. 6], so that the pressing plate (40) can use the stop edge (49) at the bottom edge to produce a limiting effect relative to the stop block (59) of the locking member (50). At this time, if it is an erroneous action, when the user does not continue to press the pressing plate (40), the buckle column (54) of the locking member (50) will not be separated from the locking rod (35), so as to avoid the situation of improper unlocking. When the user really needs to unlock, as shown in FIG. 7 , the pressing plate (40) is continuously pressed outwardly, so that the pressing plate (40) abuts against the stop block (59) of the locking member (50) with the stop edge (49), and the locking member (50) is pushed, so that the buckle column (54) on the lock seat (52) of the locking member (50) can be separated from the lock rod. (35), and the locking member (50) can synchronously compress the reset torque spring (55) to generate a reset pre-force, so that the first and second hinges (10, 20) can be folded relative to each other with the first and second hinges (11, 21) as the axis (as shown in Figure 8), thereby achieving the effect of easy unlocking and quick completion of the folding operation.

When the first and second hinges (10, 20) need to be reconnected, as shown in the ninth and tenth figures, the first and second hinges (10, 20) are pivotally connected and joined with the first and second pivots (11, 21) as the axis, and then the locking member (50) of the segmented lock assembly (30) is reset by the reset torque spring (55) on the main shaft (31), so that the lock post (54) on the lock seat (52) of the locking member (50) can be locked on the lock rod (35) due to the preload of the reset torque spring (55), so as to produce an automatic locking effect. At the same time, the locking member (50) further utilizes the function of the stop block (59) at the bottom end thereof abutting against the stop edge (49) of the pressing plate (40), so that the pressing plate (40) can be synchronously driven to the pre-pressed position. Finally, the user applies force to press the pressing plate (40) (as shown in FIG. 10), so that the lock plate (47) of the anti-slip buckle (45) on the pressing plate (40) of the segmented lock assembly (30) is locked on the oblique cone buckle portion (33) of the lock head (32), thereby generating a double safety effect, which can enhance the convenience of operation and improve the safety of its use.

Through the above-mentioned design and description, the invention folding device docking buckle structure utilizes the design that the segmented lock assembly (30) pivotally mounted on the second hinge (20) has the locking member (50) and the pressing plate (40) respectively, so that the locking member (50) can be buckled with the locking rod (35) on the first hinge (10) and the anti-slip buckle (45) of the pressing plate (40) by the locking column (54) of the locking seat (52) of the locking member (50). The lock head (32) on the first hinge (10) is limited to produce a two-stage safety buckle mechanism, which effectively prevents the unlocking of the erroneous part, and utilizes the reset torque spring (55) of the segmented lock assembly (30) to achieve the function of automatic locking, making the folding and closing and docking buckle operations more convenient. At the same time, it can have a stronger locking force, which can further improve the structural properties of the docking buckle and enhance the safety of its use.
