[0022] In this embodiment, a magnet nest 2 is provided on the armrest inner plate 1, and the magnet nest 2 and the rubber coating layer 32 are used to wrap the magnet 31; a bolt 41 is provided on the armrest inner bucket 42, and the outer surfaces of the armrest inner bucket 42 and the bolt 41 are flocked to wrap the bolt 41. Thus, the armrest inner plate 1 and the armrest inner bucket 42 can be connected by the adsorption effect of the magnet 31 on the bolt 41 to achieve the self-locking function of the armrest. Secondly, by wrapping the magnet 31 in the magnet nest 2 and the rubber coating layer 32, and flocking the outer surfaces of the bolt 41 and the armrest inner bucket 42, on the one hand, it is possible to prevent the magnet 31 and the bolt 41 from being exposed to the external environment and protect the structure of the magnet 31 and the bolt 41; on the other hand, it is possible to beautify the appearance of the armrest and enhance the visual effect.

[0023] Alternatively, if Figure 2 and Figure 3As shown, a slide groove is provided on the armrest inner plate 1, the upper and lower ends of the slide groove are open, the slide groove is set to be L-shaped, and an insertion port 11 is provided on the front side of the left end of the slide groove, and the upper end of the magnet nesting 2 is inserted into the slide groove through the insertion port 11.

[0024] In this embodiment, a slide groove is provided on the armrest inner plate 1, and an insertion port 11 is provided at the front side of the left end of the slide groove, and the upper end of the magnet nesting 2 is inserted into the slide groove from the insertion port 11, and moves along the slide groove to the right end of the slide groove. Thus, by providing the slide groove and the insertion port 11 on the armrest inner plate 1, the magnet nesting 2 can be connected to the armrest inner plate 1 by a snap-on method, which facilitates the installation and removal of the magnet nesting 2.

[0025] Alternatively, if Figures 2 to 4 As shown, a snap-in strip 5 is provided on the front and rear side walls of the slide, the front end of the snap-in strip 5 extends to the plug-in port 11, and the rear end of the snap-in strip 5 extends to the right end of the slide; the magnet nest 2 includes a first connecting sleeve 21, a connecting column 22 and a second connecting sleeve 23, the upper end of the connecting column 22 is connected to the first connecting sleeve 21, the lower end of the connecting column 22 is connected to the second connecting sleeve 23, the magnet 31 is embedded in the second connecting sleeve 23, the rubber coating 32 is connected to the second connecting sleeve 23, the connecting column 22 is used to be arranged between the two snap-in strips 5 on the front and rear side walls of the slide, the first connecting sleeve 21 is located above the snap-in strip 5, and the second connecting sleeve 23 is located below the snap-in strip 5.

[0026] In this embodiment, the magnet nesting 2 is configured to include a first connecting sleeve 21, a connecting column 22, and a second connecting sleeve 23, and a snap-in strip 5 is provided on the front and rear sides of the slide. Since the snap-in strip 5 extends from the plug-in interface 11 to the right end of the slide, the connecting column 22 is provided between the two snap-in strips 5, so that the connecting column 22 can move from the left end of the slide to the right end of the slide along the snap-in strip 5 in the slide, so as to limit the movement trajectory of the magnet nesting 2 and ensure that the magnet nesting 2 can accurately move to the right end of the slide. Secondly, the first connecting sleeve 21 is located above the snap-in strip 5, and the second connecting sleeve 23 is located below the snap-in strip 5, so that the snap-in strip 5 can limit the height of the magnet nesting 2, which is beneficial to prevent the magnet nesting 2 from escaping from the slide and the armrest inner panel 1.

[0027] Optionally, the right end side wall of the sliding groove is configured as a curved surface and is used to fit with the side wall of the connecting column 22 .

[0028] In this embodiment, by setting the right end side wall of the slide groove as an arc surface, when the connecting column 22 moves along the snap-in strip 5 to the right end of the slide groove, the side wall of the connecting column 22 fits with the right end side wall of the slide groove, which is beneficial to increase the friction between the magnet nesting 2 and the armrest inner panel 1, facilitates the limiting of the magnet nesting 2, and further prevents the magnet nesting 2 from detaching from the armrest inner panel 1.

[0029] Alternatively, if Figure 2 and Figure 3 As shown, the front end of the clamping strip 5 is provided with a chamfer.

[0030] In this embodiment, the front end of the clamping strip 5 is provided with a chamfer, wherein the thickness of the front end of the clamping strip 5 gradually increases from front to back. Thus, by providing a chamfer at the front end of the clamping strip 5, the thickness of the front end of the clamping strip 5 can be reduced, making it easier to insert the magnet nest 2 into the clamping strip 5.

[0031] Alternatively, if Figures 2 to 4 As shown, the armrest self-locking structure also includes a sliding block 61, a connecting block 62, a clamping block 63, an abutting block 64 and a spring 65. The armrest inner plate 1 is provided with a first sliding groove 12 in the left-right direction, the first sliding groove 12 is connected to the sliding groove, the clamping block 63 is slidably connected to the first sliding groove 12, and the right end of the clamping block 63 is provided with an arc surface abutting against the side wall of the connecting column 22; the upper end of the armrest inner plate 1 is provided with a second sliding groove 13 in the left-right direction. The sliding block 61 is slidably connected to the second sliding groove 13, one end of the spring 65 is connected to the side wall of the second sliding groove 13, and the other end is connected to the sliding block 61; the abutment block 64 is provided with a semicircular shape, the lower end of the abutment block 64 is connected to the sliding block 61, and the lower end of the abutment block 64 is connected to the clamping block 63 through the connecting block 62, the arc surface of the abutment block 64 faces the first connecting sleeve 21, and is used to abut against the side wall of the first connecting sleeve 21.

[0032] Specifically, the left portion of the second sliding groove 13 is located on the armrest inner plate 1 , and the right portion is located on the clamping strip 5 .

[0033] In this embodiment, when the magnet nest 2 is pushed to move in the slide groove, the first connecting sleeve 21 abuts against the arc-shaped side wall of the abutment block 64, pushing the abutment block 64 to move to the left end; on the one hand, the abutment block 64 is connected to the clamping block 63 through the connecting block 62, and can synchronously drive the clamping block 63 to move to the left in the first sliding groove 12; on the other hand, the abutment block 64 is connected to the sliding block 61, and the sliding block 61 is slidably connected to the second sliding groove 13, and the sliding block 61 is connected to the spring 65. When the abutment block 64 moves to the left end, it drives the sliding block 61 to move to the left in the second sliding groove 13 and compresses the spring 65. When the magnet nest 2 moves to the right end of the slide groove, the spring 65 extends, pushing the sliding block 61 to move rightward in the second sliding groove 13, and driving the abutment block 64 to move rightward, driving the clamping block 63 to move rightward in the first sliding groove 12, and utilizing the right end arc surface of the clamping block 63 to abut against the left side wall of the connecting column 22, thereby realizing the limiting effect on the magnet nest 2.
