AI Technical Summary
The locking mechanism of existing car center consoles has poor tightness, resulting in an installation gap between the cover and the body, causing shaking and noise, which affects the driving or riding experience.
The locking assembly includes a latch component, an unlocking plate, and a spring-loaded traction component. By driving the unlocking plate to rotate, the latch component is forced to rotate to the open state, thereby separating the locking groove from the locking pin, ensuring a more secure lock and eliminating installation gaps.
It effectively eliminates the relative rotation between the locking tongue and the unlocking plate, ensuring a tighter fit between the center armrest box lid and the box body when locked, avoiding shaking and noise, and improving the driving or riding experience.

Abstract
Claims
1. A central armrest box locking mechanism of an automobile, comprising two sets of brackets (1) for being fixedly installed in the interior of the vehicle, and an armrest box cover (2) being rotatably assembled between the two sets of brackets (1), characterized in that: An installation gap (a) is provided between the side of the armrest box cover (2) and one of the brackets (1). Within the installation gap (a), a locking assembly is provided on the side of the armrest box cover (2), and a locking pin (3) is fixed on the side of the bracket (1). The locking assembly includes a mounting bracket (4) fixed on the side of the armrest box cover (2). Two support shafts (5) are arranged in parallel on the mounting bracket (4). A locking tongue component (6) and an unlocking plate (7) are rotatably mounted on the two support shafts (5). An elastic traction component (8) is provided between the locking tongue component (6) and the unlocking plate (7). The locking tongue component (6) has a locking groove (6a). In the locked state, the locking pin (3) is restricted in the locking groove (6a), and the armrest box cover (2) is fixed relative to the bracket (1); By manipulating the unlocking piece (7) to rotate away from the locking tongue component (6), the locking tongue component (6) can be driven to rotate under the action of the elastic traction component (8), so that the locking groove (6a) of the locking tongue component (6) releases the restriction on the locking pin (3), and the armrest box cover (2) can rotate upward relative to the bracket (1).
2. The automobile center armrest box locking mechanism according to claim 1, characterized in that: The unlocking piece (7) has a first positioning groove (7a1) and a second positioning groove (7a2) on the side near the locking tongue component (6). The locking tongue component (6) has a positioning part (6b) on the side near the unlocking piece (7). In the locked state, the positioning part (6b) is constrained in the first positioning groove (7a1). During the unlocking process of the unlocking piece (7) driving the locking tongue component (6) to unlock, the positioning part (6b) can slide from the first positioning groove (7a1) into the second positioning groove (7a2) so that the locking tongue component (6) remains in the unlocked state. One end of the locking groove (6a) is open. During the downward rotation of the armrest box cover (2) in the closing direction, one side of the open end of the locking groove (6a) can hit the locking pin (3), and the passively driven positioning part (6b) slides from the second positioning groove (7a2) into the first positioning groove (7a1) so that the locking tongue part (6) automatically resets to the locked state.
3. The automobile center console box lock mechanism according to claim 2, characterized by: The latch component (6) has a protrusion (6d) extending toward the side where the unlocking plate (7) is located. The protrusion (6d) extends beyond the extension length of the positioning part (6b). The protrusion (6d) is used to strike the locking pin (3).
4. The automobile center console box lock mechanism according to claim 3, characterized by: The unlocking piece (7) includes an active unlocking piece (7a) and a passive unlocking piece (7b). The active unlocking piece (7a) has a cable mounting hole (7a3) at its top. The passive unlocking piece (7b) has a transmission rod (7b1) extending toward the direction of the active unlocking piece (7a). One side of the active unlocking piece (7a) abuts against the transmission rod (7b1). When the active unlocking piece (7a) is pulled by the cable and rotates in the unlocking direction, it can be driven by the transmission rod (7b1) to force the passive unlocking piece (7b) to rotate synchronously.
5. The automobile center console box locking mechanism according to claim 4, characterized by: The first positioning groove (7a1) and the second positioning groove (7a2) are both formed on the side of the active unlocking piece (7a) near the latch member (6), and the protrusion (6d) is formed on the side where the passive unlocking piece (7b) is located.
6. The automobile center console box locking mechanism according to claim 4, characterized by: The elastic traction component (8) is a tension spring, and the locking tongue component (6) is provided with a tension spring fixing hole (6c). The two ends of the tension spring are respectively fixedly installed on the tension spring fixing hole (6c) and the transmission rod (7b1).
7. The automobile center console box locking mechanism according to claim 4, characterized by: The mounting bracket (4) includes a first mounting bracket (4a) and a second mounting bracket (4b) arranged in parallel. The support shaft (5) is fixedly inserted between the first mounting bracket (4a) and the second mounting bracket (4b). The first mounting bracket (4a) is fixedly installed on the side of the armrest box cover (2).
8. The automobile center console box locking mechanism according to claim 7, characterized by: The second mounting bracket (4b) is an n-shaped bracket. In the locked state, the second mounting bracket (4b) and the locking groove (6a) of the locking tongue component (6) form a strip-shaped mounting area (b), and the locking pin (3) is locked in the strip-shaped mounting area (b).
9. The automobile center console box locking mechanism according to claim 8, characterized by: A plastic patch (9) is provided at the lower end of the second mounting bracket (4b) corresponding to the position of the strip mounting area (b).
10. The automobile center console box locking mechanism according to claim 7, characterized by: The second mounting bracket (4b) has a slot (4b1) on the side near the unlocking piece (7). The lower end of the active unlocking piece (7a) has a downwardly extending protrusion (7a4). A torsion spring (10) is also provided on the support shaft (5) on which the unlocking piece (7) is mounted. The two ends of the torsion spring (10) abut against the slot (4b1) and the protrusion (7a4) respectively.
