Technical Field

[0001] This utility model relates to the field of automotive armrest technology, and in particular to an armrest single-sided opening lock assembly. Background Technology

[0002] A car armrest box is a component installed between the two front seats of a car. The box is used to store items, and the armrest on top allows the driver to rest their arm during long drives, thus enabling the arm to get an effective rest.

[0003] Currently, most car armrests open by flipping, with the opening button located on the side. To facilitate opening for both the driver and passenger, opening buttons are provided on both sides of the armrest. For example, patent CN209813848U discloses an easy-to-unlock vehicle armrest storage box, including a box body and a flip-mounted lid. The lower surface of the lid has at least one downward-protruding locking hook, and the upper surface of the box body has locking holes corresponding to the corresponding locking hooks. Each outer edge of the lid has an unlocking button, and both unlocking buttons can simultaneously activate the locking hooks through the same locking mechanism. The locking mechanism includes a rotatable gear mounted on the lid and two parallel racks meshing on either side of the gear. The two unlocking buttons are connected to their respective racks. Unlocking requires both racks to retract simultaneously, resulting in high unlocking resistance. Furthermore, if one side jams, unlocking is impossible, leading to a relatively high risk of opening failure. Utility Model Content

[0028] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0029] like Figures 1 to 7 As shown, the single-sided unlocking lock assembly of the handrail includes a handrail body 1 and a locking tongue 3. Both sides of the handrail body are provided with unlocking buttons, namely a one-sided unlocking button 2 and a other-sided unlocking button 4. A lock cylinder structure for driving the locking tongue to move is provided between the two unlocking buttons on the handrail body. A through hole for the locking tongue to pass through is provided at the end of the handrail body. A lock hole is provided on the handrail housing corresponding to the end of the locking tongue.

[0030] The lock cylinder structure includes a housing, a pair of pressing linkage rods 5, and a return spring for resetting the lock tongue. The inner end of the lock tongue slides inside the housing, and the outer end of the lock tongue extends out from the housing. The outer end of the pressing linkage rod is connected to the opening button on the corresponding side. The lock tongue is provided with a drive pin, and the inner ends of the pair of pressing linkage rods are each provided with a push plate 501 that can push the drive pin.
