Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] like Figure 1 As shown, this embodiment of the invention provides a movable car armrest lock structure, which mainly includes: a handle 1, a connecting assembly, a latch 9, a reset assembly, and a locking hook 8. The handle 1 has a horizontally oriented sliding groove, and the upper end of the latch 9 is mounted in the sliding groove via a first rotating shaft 2; the latch 9 can slide within the sliding groove via the first rotating shaft 2, and the latch 9 can rotate around the first rotating shaft 2. A limiting block 104 is provided on the handle 1, and the lower edge of the limiting block 104 abuts against the upper edge of the latch 9. The limiting block 104 is used to drive the latch 9 to rotate synchronously during the rotation of the handle 1. The reset assembly is fixed to the lower cover 13 of the armrest; the upper end of the locking hook 8 is mounted on the reset assembly, and the reset assembly is used to drive the locking hook 8 to reset. The lower end of the latch 9 cooperates with the upper end of the locking hook 8, and the lower end of the latch 9 is used to drive the locking hook 8 to rotate relative to the reset unit. The lower end of the locking hook 8 is designed as a hook structure, and the lower end of the locking hook 8 matches the armrest box to achieve the locking function. The handle 1 is connected to the armrest cover 11 via a connecting component.

[0039] Specifically, the handle 1 includes a movable part and a pressing part. The movable part includes a base plate 101, a first upright plate, and a second upright plate 103. The first upright plate is fixed to one side of the base plate 101, and the second base plate 101 is fixed to the other side of the base plate 101. The first upright plate and the second upright plate 103 are arranged opposite to each other. A first sliding groove is formed on the first upright plate, and a second sliding groove 106 is formed on the second upright plate 103. The first sliding groove and the second sliding groove 106 are arranged opposite to each other. One side of the upper end of the latch 9 is connected to the first sliding groove through a first pivot 2, and the other side of the upper end of the latch 9 is connected to the second sliding groove 106 through another first pivot 2. Limiting blocks 104 are respectively provided at the upper ends of the first base plate 101 and the second upright plate 103. The pressing part is integrally fixedly connected to the base plate 101.

[0040] The locking tongue 9 includes a first leg, a second leg, and a tongue-shaped portion. The first leg and the second leg are respectively fixed to the upper end of the tongue-shaped portion; the first leg and the second leg are arranged opposite to each other; the upper ends of the first leg and the second leg are respectively provided with pivot mounting holes, and the two pivot mounting holes are respectively mounted on corresponding slide grooves through the first pivot 2. The tongue-shaped portion is used to cooperate with the locking hook 8.

[0041] The reset assembly includes: a pivot seat 7, a second pivot 6, and a return spring 5. The pivot seat 7 has connecting ears on both sides for fixed connection with the lower cover 13 of the armrest. A slot is provided in the middle of the pivot seat 7, through which the second pivot 6 passes and is positioned; the return spring 5 is mounted on the second pivot 6 and engages with a locking hook 8.

[0042] The locking hook 8 includes a connecting part and a hook-shaped part. The hook-shaped part is fixed to the lower end of the connecting part. A through hole is provided at the upper end of the connecting part; the upper end of the connecting part extends from the lower end of the rotating shaft seat 7 into the slot, and the second rotating shaft 6 passes through the through hole; the return spring 5 is limited at the upper end of the connecting part.

[0043] The connecting components include: connecting rods 3 and third pivots 4. Two connecting rods 3 are arranged opposite each other; the two connecting rods 3 are movably connected to the handle 1 via a third pivot 4; the two connecting rods 3 are also connected to the armrest cover 11 via another third pivot 4.

[0044] This invention provides a movable car armrest box lock structure for use with an upper armrest cover 11 and a lower armrest cover 13. The armrest box cover consists of an upper armrest cover 11 and a lower armrest cover 13. The lower armrest cover 13 is fixed, while the upper armrest cover 11 can slide on the lower armrest cover 13 via a slide rail. A handle 1 is connected to the upper armrest cover 11 via a connecting rod 3 and a third pivot 4, and the handle 1 can move around the third pivot 4. Simultaneously, the handle 1 is connected to the lower armrest cover 13 via its own sliding groove structure and a first pivot 2, and the handle 1 can also move around the first pivot 2. A locking tongue 9 is combined with the handle 1 via the first pivot 2 and can move synchronously with the handle 1 around a second metal pivot 6. A locking hook 8 is fixed to the lower armrest cover 13 via the second pivot 6, a pivot seat 7, and a return spring 5, and the locking hook 8 can move around the second pivot 6.

[0045] When the handrail is in its initial position, such as Figure 2 When the user pulls the handle 1, the handle 1 rotates along the first pivot 2. Simultaneously, the limiting block 104 on the handle 1 causes the locking tongue 9 to rotate synchronously. The locking tongue 9 pushes the locking hook 8, disengaging the locking mechanism of the armrest box 12 from the locking part, thus unlocking the armrest cover from the armrest box 12. At this point, the armrest cover can be opened. Figure 4 When the user releases the handle 1, the locking hook 8 returns to the locked state under the action of the return spring 5, as if... Figure 3 .

[0046] When the handrail slides forward, as Figure 5 At this time, the armrest cover 11 drives the handle 1 to slide forward synchronously along the slide groove via the connecting rod 3, as shown. Figure 6 Similarly, when the armrest slides to any position, the user pulls the latch 1. The latch 1 and the locking tongue 9 work together to push the locking hook 8, thus unlocking the armrest cover from the armrest housing 12. At this point, the armrest cover can be opened, such as... Figure 7 Release the handle 1, and the locking hook 8 returns to the locked state.
