At the upper ends of the two ear plate sections of the bottom cover, a first optical axis is fixedly connected. A sliding sleeve is hinged on the first optical axis. A locking hook is elastically slidably connected to the free end of the sliding sleeve. A second optical axis is arranged in the bottom cover below the first optical axis. The second optical axis is arranged parallel to the first optical axis. A tension spring is connected between the corresponding ends of the two ends of the second optical axis and the first optical axis. A connecting piece is hinged on the second optical axis. A pin shaft parallel to the second optical axis is arranged in the sliding sleeve. The other end of the connecting piece is hinged to the sliding sleeve through the pin shaft. A hook body is arranged on the surface of the locking hook facing the connecting piece. A clamping portion cooperating with the hook body is arranged on the connecting piece. A locking tongue is fixedly connected to the second optical axis.

Detailed implementation manners

[0017] The technical solution of the present application will be further described and illustrated below in conjunction with the accompanying drawings and embodiments.

[0018] As Figures 1-3 shown, it is a self-locking locking mechanism for a movable column of a side curtain vehicle, including a bottom cover 1 in a U shape. At the upper ends of the two ear plate sections of the bottom cover 1, a first optical axis 2 is fixedly connected. A sliding sleeve 3 is hinged on the first optical axis 2. A locking hook 4 is elastically slidably connected to the free end of the sliding sleeve 3. A second optical axis 5 is arranged in the bottom cover 1 below the first optical axis 2. The second optical axis 5 is arranged parallel to the first optical axis 2. A tension spring 6 is connected between the corresponding ends of the two ends of the second optical axis 5 and the first optical axis 2. A connecting member 7 is hinged on the second optical axis 5. A pin shaft 8 parallel to the second optical axis 5 is arranged in the sliding sleeve 3. The other end of the connecting member 7 is hinged to the sliding sleeve 3 through the pin shaft 8. A hook body 401 is arranged on the surface of the locking hook 4 facing the connecting member 7. A clamping portion 701 cooperating with the hook body 401 is formed on the connecting member 7. A locking tongue 9 is fixedly connected to the second optical axis 5. The connecting member 7 includes a connecting plate 702 with a U-shaped cross section. Hanging ears 703 are arranged at the free ends of the two ear plate sections of the connecting plate 702. The two ends of the connecting plate 702 are respectively sleeved on the second optical axis 5 and the pin shaft 8 through the corresponding hanging ears 703. The locking hook 4 includes a sliding portion 402 slidably connected to the sliding sleeve 3. A pulling hand portion 403 arranged in a mirror-image "S" shape is integrally arranged at the lower end of the sliding portion 402. A tension spring is arranged between the sliding sleeve 3 and the sliding portion 402. An outer swing arm 10 is hinged outside the upper end of the bottom cover 1.

[0019] When the locking of the mechanism is required, the locking hook 4 in the unfolded state is pressed downward into the bottom cover 1. During the downward rotation of the locking hook 4, due to the fixed length of the connecting member 7, the connecting member 7 gradually changes from an inclined state to a vertical state and is arranged inside the bottom cover 1. During this process, the second optical axis 5 drives the locking tongue 9 to move vertically downward. At the same time, the tension spring 6 is in a tensioned state. During the downward movement of the locking tongue 9, it is clamped with the hook plate of the external mounting seat to form left and right limits, avoiding the left and right movement of the movable column on the side curtain vehicle. At the same time, when the locking hook 4 rotates downward, the hook body 401 in the sliding sleeve 3 will be clamped on the clamping portion 701 on the surface of the connecting member 7. The tension spring arranged between the sliding sleeve 3 and the sliding portion 402 will prevent the sliding sleeve 3 from separating from the connecting member 7. When the unlocking of the mechanism is required, the pulling hand portion 403 of the sliding sleeve 3 is pulled downward, so that the hook body 401 in the sliding sleeve 3 is separated from the clamping portion 701, and then the sliding sleeve 3 is rotated to restore to the original unfolded state, completing the unlocking of the mechanism.

[0020] The present utility model is not limited to the above embodiments. Based on the technical solutions disclosed in the present utility model, those skilled in the art can make some substitutions and deformations to some of the technical features without creative labor according to the disclosed technical content, and these substitutions and deformations are all within the protection scope of the present utility model.
