Description

Wrapped shaft construction with double stops

technical field

The utility model relates to a rotating shaft structure, in particular to a covered rotating shaft structure with double stops.

Background technique

According to general consumer electronic products with flip covers, such as portable computers, mobile phones, electronic dictionaries and portable audio-visual playback devices, etc., the main body is generally placed in the lower half, and the hinge device (or called The rotating shaft device) is connected with the cover body portion of the upper half, so that the cover body portion can be opened and closed by rotation relative to the main body portion. Therefore, the hinge device is also a major factor in determining the quality of the above-mentioned consumer electronic products.

As shown in China Taiwan Patent Announcement No. 420321, it discloses a covered hinge device, and its hinge device is composed of a fixed seat, a plurality of pipe spring frames, a positioning plate and a pivot. The fixing seat has a combination hole, an I-shaped groove and a set of stoppers respectively, and the pipe spring frame is combined with the combination hole and the I-shaped groove, and the pipe spring frames are provided with shaft holes, and the pivot shaft has an oil groove. into the shaft hole, and the rotating shaft penetrates into a positioning plate, so that when rotating, the pipe spring frames form a frictional torque to the rotating shaft. In order to provide the expected bi-directional positioning function of this case, two stoppers protrude from the outer wall of the coupling hole of the fixing seat, which serve as stops when the sector piece protruding from the periphery of the positioning plate rotates.

Although this case can provide the stopper function of the hinge device, its deficiency is that the two stoppers protruding from the outer wall of the joint hole are integrally cast with the fixing seat, and their strength and rigidity are often much lower than that of the positioning plate after heat treatment. Therefore, the sector piece of the positioning plate repeatedly uses the two stoppers as the limit of the opening and closing angle, which often causes the breakage between the stoppers and the fixing seat due to deformation. Furthermore, since this case only provides a single stop device, so that when the hinge is opened and closed, the pivot positioning plate is against the outer wall of the joint hole of the fixing seat and two stops are relatively protruded, and the weight of the display screen is added. , often make the single stop device (block) bear a very large direct impact force, and cause the fracture of these blocks, and then reduce the service life of the rotating shaft structure, which is really a fly in the ointment.
