[0027] See also Figure 1-6The utility model provides a technical solution: a telescopic car seat armrest, including an armrest 1, a telescopic component 2 is installed at the center of the armrest 1, the telescopic component 2 adjusts the surface area of ​​the armrest 1 when it is extended and retracted, a rotating component 3 is installed in the inner cavity of the armrest 1, and a connecting component 5 is installed on the rotating component 3. The connecting component 5 is used to connect the rotating component 3 and the telescopic component 2. The rotating component 3 is connected to the driving component 4. The driving component 4 provides power for the rotation of the rotating component 3. When the rotating component 3 moves forward and backward, the telescopic component 2 is driven to extend and retract through the connecting component 5.

[0028] The armrest 1 is the armrest of the car seat. After the telescopic component 2 produces a telescopic action, the area of ​​the armrest 1 can be increased. After the driving component 4 works, it drives the rotating component 3 to rotate. After the rotating component 3 rotates, it drives the connecting component 5 to produce displacement. After the connecting component 5 produces displacement, it drives the telescopic component 2 to expand and contract inside the armrest 1 to change the area of ​​the armrest 1.

[0029] In some embodiments, the telescopic component 2 includes an expansion panel 21, there are two expansion panels 21, the two expansion panels 21 are installed on the top of the armrest 1 through the telescopic cavity 22, the telescopic cavity 22 is opened in the middle of the armrest 1, and the expansion panel 21 is inserted into the inside of the telescopic cavity 22.

[0030] The expansion panel 21 is used to increase the placement area of ​​the armrest 1 after being extended and retracted, wherein the expansion panel 21 is extended and retracted inside the retractable cavity 22 to complete the retractable action to adjust the area of ​​the armrest 1.

[0031] In some embodiments, the rotating assembly 3 includes a rotating rod 31 , both ends of which are connected to the inner wall of the armrest 1 through bearings 34 , and screws 33 are installed on the outer walls of both ends of the rotating rod 31 , and a screw barrel 32 is threadedly installed on the outer wall of the screw 33 .

[0032] The rotating rod 31 rotates on the armrest 1 under the action of the bearing 34. After the rotating rod 31 rotates, it drives the screw 33 to rotate. When the screw 33 rotates, since the screw barrel 32 is limited by the connecting component 5, it performs threaded movement on the screw 33 to drive the connecting component 5 to move, so that the connecting component 5 pushes the expansion panel 21 to move and adjust. The screws 33 at both ends have opposite thread directions. When the rotating rod 31 rotates, it can drive the corresponding screw barrel 32 to rotate at the same time, allowing the expansion panel 21 to move synchronously.

[0033] In some embodiments, the drive assembly 4 includes a DC motor 41 and a second pulley 44. The second pulley 44 is installed at the center of the outer wall of the rotating rod 31. The DC motor 41 is installed inside the armrest 1. The output end of the DC motor 41 is installed with a first pulley 42. The first pulley 42 is connected to the second pulley 44 through a belt 43.

[0034] The DC motor 41 is the power source for driving the rotating rod 31 to rotate. The DC motor 41 can rotate in both forward and reverse directions. When working, the DC motor 41 drives the first pulley 42 to rotate. The first pulley 42 drives the second pulley 44 to rotate through the belt 43. The rotation of the second pulley 44 also drives the rotating rod 31 to rotate, causing the rotating rod 31 to rotate in the forward and reverse directions, thereby controlling the retraction and extension of the expansion panel 21.

[0035] In some embodiments, the connecting assembly 5 includes a pushing bend plate 52, one end of which is connected to the screw barrel 32, and the other end of the pushing bend plate 52 is installed with a connecting plate 53, which slides on the armrest 1 through the sliding groove 51, and the connecting plate 53 is connected to the extension panel 21.

[0036] When the turning plate 52 moves, it drives the connecting plate 53 to limit the linear position inside the sliding groove 51, and also limits the rotation state of the screw barrel 32. That is, when the screw 33 rotates, the screw barrel 32 is limited by the sliding of the connecting plate 53 inside the sliding groove 51 and cannot rotate with the screw 33. It can only be driven by the rotation of the screw 33 to produce linear displacement. The movement of the connecting plate 53 drives the extension panel 21 to extend and retract.

[0037] In some embodiments, the grooves of the first pulley 42 and the second pulley 44 are internally machined with a frosted layer.

[0038] The frosted layer increases the friction inside the first pulley 42 and the second pulley 44 to reduce the friction between the first pulley 42 and the second pulley 44 and the belt 43 , thereby preventing slipping during the transmission process.

[0039] In some embodiments, the extension panel 21 is detachably mounted on the connecting plate 53 by bolts. The extension panel 21 can be removed from the connecting plate 53 for replacement, or the interior of the armrest 1 can be exposed after the extension panel 21 is removed for maintenance.

[0040] In some embodiments, the surface material of the expansion panel 21 is consistent with that of the armrest 1 , so that the expanded area of ​​the armrest 1 is consistent with the material of the main body.

[0041] In some embodiments, the thread directions of the two lead screws 33 are opposite, and the two lead screws 33 can allow the screw barrel 32 to move in opposite directions.

[0042] In some embodiments, the connecting plate 53 is made of engineering plastics, which has high strength and can increase the service life of the connecting plate 53 .

[0043] Working principle: When different groups of people place their arms on the armrest 1, different groups of people have different requirements for the placement area. The switch is pressed to control the DC motor 41 to work, driving the first pulley 42 to rotate. The first pulley 42 drives the second pulley 44 to rotate through the belt 43. The rotation of the second pulley 44 also drives the rotating rod 31 to rotate. The rotating rod 31 rotates on the armrest 1 under the action of the bearing 34. After the rotating rod 31 rotates, it drives the screw 33 to rotate. When the screw 33 rotates, since the barrel 32 is limited by the connecting component 5, it performs threaded motion on the screw 33, pushing the turning plate 52 to drive the connecting plate 53 inside the sliding groove 51 during movement. The movement of the connecting plate 53 drives the expansion panel 21 to extend inside the telescopic cavity. After the expansion panel 21 is extended, the area of ​​the armrest 1 is increased. When the expansion panel 21 needs to be retracted, the DC motor 41 is rotated in the opposite direction, and the above action is repeated to retract and reset the expansion panel 21.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
