[0028] The following is in conjunction with the appendix Figures 1 to 4 This application will be described in further detail.

[0029] This application provides a rocker arm type electric switch mechanism, including: a support 3, a triangular rocker arm 1, and a straight rocker arm 2.

[0030] Specifically, such as Figure 1 As shown, the support 3 is fixedly installed on the body 11. The support 3 has two mounting edges: one for mounting the triangular rocker arm 1 and the straight rocker arm 2, and the other for mounting the long tension spring 4. Figure 2As shown, the triangular rocker arm 1 includes an integrally formed upper rocker arm, a middle rocker arm, and a lower rocker arm. The upper rocker arm is triangular in shape and has two joints at its upper part. The upper part of the straight rocker arm 2 has one joint. The upper rocker arm and the upper part of the straight rocker arm 2 are hinged to the support 3. A first adjusting bolt 8 is installed on the upper rocker arm with a nut 10. The head of the first adjusting bolt 8 abuts against the support 3 to adjust the state of the triangular rocker arm 1. The middle rocker arm has a first connecting part and a second connecting part that are perpendicular to each other. The first connecting part is connected to the support 3 by a long tension spring 4, and the second connecting part is connected by a short tension spring. 5 is connected to the middle of the straight rocker arm 2; the lower rocker arm is provided with a mounting groove, in which the switch 6 is installed; the lower part of the straight rocker arm 2 is fitted with a nut 10 and a second adjusting bolt 9 is installed; the second adjusting bolt 9 corresponds to the position of the switch 6; the second adjusting bolt 9 is used to adjust the amount of the switch 6 being pressed in; the locking mechanism rocker arm 14 of the locking mechanism 13 abuts against the triangular rocker arm 1; the hatch stop pin 15 on the hatch 12 abuts against the straight rocker arm 2; when the locking mechanism 13 is locked and the hatch 12 is closed, the triangular rocker arm 1 can swing backward under the push of the locking mechanism rocker arm 14, and the straight rocker arm 2 can swing forward under the push of the hatch stop pin 15.

[0031] In a preferred embodiment of this application, the upper rocker arm and the upper part of the straight rocker arm 2 are hinged to the support 3 by the same bolt.

[0032] In a preferred embodiment of this application, the first adjusting bolt 8 is a round-headed adjusting bolt.

[0033] In a preferred embodiment of this application, a weight-reducing hole is provided on the first connecting part, a limit pin 7 is installed on the second connecting part, and a short tension spring 5 is connected to the limit pin 7.

[0034] In a preferred embodiment of this application, the second adjusting bolt 9 is a flat-head adjusting bolt.

[0035] Before installation of the rocker arm type electric switch mechanism of this application, it is confirmed that the locking mechanism 13 and the hatch 12 are both locked and closed, and the electric switch 6 is already installed on the triangular rocker arm 1. The tooling is used to install the support 3, and then the triangular rocker arm 1, the straight rocker arm 2 and the two tension springs are installed in sequence. After assembly, the positions of the triangular rocker arm 1 and the straight rocker arm 2 are adjusted by the round head and flat head adjusting bolts respectively to complete the installation.

[0036] The rocker-arm type electric switch mechanism of this application monitors the locking status of the locking mechanism 13 via the triangular rocker arm 1 and the closing status of the hatch 12 via the straight rocker arm 2. If either component is not in position, the straight rocker arm 2 will continuously press the electric switch 6 on. Figure 4As shown, when the locking mechanism 13 of the hatch 12 is locked and the hatch 12 is closed, the locking mechanism rocker arm 14 on the locking mechanism 13 pushes the triangular rocker arm 1 to swing backward, and the hatch stop pin 15 on the hatch 12 pushes the straight rocker arm 2 to swing forward until the action of the short tension spring 5 is overcome and the two disengage, the switch 6 is disconnected, and the signal changes. After the switch 6 is disconnected, a certain gap is maintained between the switch contact and the second adjusting bolt 9 of the straight rocker arm 2, so that even if the fuselage 11 is subjected to a certain deformation under load in the air, the two will not come into contact and press the switch 6.

[0037] The rocker arm type switch mechanism of this application can monitor the relative movement of two components. The switch signal will only be triggered and changed when both components have moved into position; otherwise, it will not be triggered. This switch mechanism is compact, easy to adjust, has the ability to adapt to certain body deformations, can maintain signal stability, and is lightweight.

[0038] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
