However, the current armrest pull-cord lock mechanism is complex, cumbersome to assemble and change, and the lock tongue is exposed when the armrest is opened, making it visible and unsightly. Therefore, a simple, reliable, and hidden lock tongue structure is needed. Utility Model Content

[0003] The purpose of the utility model is to solve the above problems in the prior art and to propose a hidden locking structure for a rear backrest armrest pull cord lock tongue.

[0004] The purpose of the utility model is achieved through the following technical solutions: a rear backrest armrest pull cord lock tongue hidden locking structure, comprising an armrest upper cover plate, an armrest lower cover plate and a locking decorative plate, wherein a pull cord, an upper decorative cover, a lower decorative cover, an upper shaft sleeve, a lower shaft sleeve, an axle pin and a return spring are arranged inside the armrest upper cover plate, the upper decorative cover and the lower decorative cover are welded and installed to form a decorative cover, the upper shaft sleeve and the lower shaft sleeve clamp the axle pin and install it in the middle to form a shaft sleeve, the pull cord passes through the decorative cover, the decorative cover is installed to the armrest upper cover plate, and the other end is fixed to the shaft sleeve, the return spring is installed on the shaft sleeve and installed together to the armrest upper cover plate.

[0005] Furthermore, a locking rod and a spring are provided inside the armrest lower cover plate, and the locking rod and the spring are installed on the armrest lower cover plate.

[0006] Furthermore, the ball head of the shaft sleeve on the upper cover plate of the armrest is inserted into the groove of the locking rod, and the pull rope is pulled, and the locking rod is withdrawn from the locking groove of the locking decorative plate, thereby unlocking the door.

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] The locking structure of the present invention is simple and cleverly coordinated. The locking structure can be locked by using a pull rope, a spring and a shaft sleeve. The pull rope can directly realize the unlocking movement through the decorative cover. Compared with other pull rope unlocking structures that require another shaft to realize unlocking, the present invention is simpler and can well hide the lock tongue after opening, which plays an aesthetic role. At the same time, the present invention adopts a small number of parts, is easy to assemble and replace, and has low cost, which can effectively reduce product cost.

[0017] See also Figures 1-8 The utility model relates to a hidden locking structure of a rear armrest pull cord lock tongue, comprising an armrest upper cover plate 1, an armrest lower cover plate 11 and a locking decorative plate 14. A pull cord 2, an upper decorative cover 3, a lower decorative cover 4, an upper shaft sleeve 6, a lower shaft sleeve 7, an axle pin 8 and a return spring 10 are arranged inside the armrest upper cover plate 1. The upper decorative cover 3 and the lower decorative cover 4 are welded and installed to form a decorative cover 5. The upper shaft sleeve 6 and the lower shaft sleeve 7 clamp the axle pin 8 in the middle to form a shaft sleeve 9. The pull cord 2 passes through the decorative cover 5, and the decorative cover 5 is installed on the armrest upper cover plate 1. The other end of the pull cord 2 is fixed on the ball head 15 of the shaft sleeve 9. At the same time, the return spring 10 is installed on the shaft sleeve 9 and installed together with the armrest upper cover plate 1.

[0018] A spring 12 and a locking rod 13 are provided inside the armrest lower cover 11, and the spring 12 and the locking rod 13 are installed on the armrest lower cover 11. A return spring 10 is provided on the shaft sleeve 9, and the shaft sleeve 9 and the return spring 10 are installed on the armrest upper cover 1 together.

[0019] The ball head 15 on the sleeve 9 of the armrest upper cover 1 engages with the groove 16 of the locking rod 13 on the lower armrest cover 10. The upper armrest cover 1 and lower armrest cover 11 are welded and assembled. When the pull cord 2 is pulled in any direction, the locking rod 13 is forced out of the locking groove 17 of the locking decorative plate 14, unlocking the armrest. Simultaneously, the armrest opens downward in the Z direction. When fully opened, the locking rod 13 is concealed by the locking decorative plate 14, and the armrest also obscures the locking groove 17 of the locking decorative plate 14. The upper sleeve 6 and lower sleeve 7 are connected by the pin 8, which is mounted between the sleeve 9. The ball head 15 of the sleeve 9 is seated on the lower sleeve 7 and engages with the groove 16 of the locking rod 13. The pull cord 2 is fixed to the ball head 15. Pulling the pull cord 2 drives the ball head 15, which in turn drives the locking rod 13 out of the locking groove 17, opening the armrest and unlocking it. When the pull rope 2 is released, the return spring 10 on the pin 8 drives the ball head 15 of the pin 9 to reset, thereby resetting the pull rope. At the same time, the spring 12 also drives the locking rod 13 to reset, closing the armrest, and the locking rod 13 is snapped into the locking groove 17 and locked again.

[0020] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
