Description

Technical Field

[0001] The present invention relates to the field of toggle switches, and in particular, to a self - resetting toggle structure with elastic energy storage and synchronous action. Background Art

[0002] Generally, a self - resetting toggle switch uses a fork to press a spring to realize the action of the actuator. Due to reasons such as part size, assembly deviation, non - unique action path, and spring sliding of the actuator, the force direction of the actuator is inconsistent, the actions of the switch actuators are not synchronous, and there is a difference in the sequence of current connection. It is difficult to meet the usage requirements in aviation products with high requirements for current supply synchronization. In addition, it lacks an elastic energy storage component, consumes a large amount of energy during the action process, and has a strong impact on parts during the self - reset process. In short, the overall action consistency of the existing self - resetting toggle switch actuator is poor, the energy consumption is large, and the impact is strong, which will reduce the service life of the product and affect the switch performance. Summary of the Invention

[0003] The object of the present invention is to provide a self - resetting toggle structure with elastic energy storage and synchronous action, which can enable the actuator to perform synchronous actions, have low energy consumption, and small impact during self - reset, thereby improving the operation feel, use reliability, life, and performance of the product.

[0024] The present invention will be further described in detail below in connection with the accompanying drawings through specific implementation manners. It should be noted here that the description of these implementation manners is used to help understand the present invention, but does not limit the present invention. In addition, the technical features involved in the various implementation manners of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] Please refer to Figures 1 to 8 , what is shown in the figure is a self - resetting toggle structure with elastic energy storage and synchronous action, belonging to the field of toggle switches.

[0026] The self - resetting toggle structure is composed of components such as a horizontal slide rail 1, an upper slider 2, a lower slider 3, a spring energy storage component 4, a left actuator 5, and a right actuator 6.

[0027] The horizontal slide rail 1 is cylindrical. The horizontal slide rail 1 extends in the left - right direction. The inside of the horizontal slide rail 1 has a built - in slide rail space. The left and right ends of the horizontal slide rail 1 are respectively provided with a left fixed pressure plate 12 and a right fixed pressure plate 13. A slide rail limiting groove 11 extending in the left - right direction is formed on the horizontal slide rail 1. In this embodiment, the slide rail limiting groove 11 penetrates from the top surface of the horizontal slide rail 1 to the bottom surface of the horizontal slide rail 1.

[0028] A slider perforation 21 is formed on the upper slider 2. The slider perforation 21 and the transverse slide rail 1 have a common axial direction. The slider perforation 21 and the transverse slide rail 1 are in coaxial hole fit. Thereby, the upper slider 2 can slide left and right along the transverse slide rail 1. In this embodiment, the number of the transverse slide rails 1 is two, which are arranged at the front and rear ends of the upper slider 2 to better ensure the smooth movement of the upper slider 2. A handle 22 is installed on the upper slider 2.

[0029] The lower slider 3 is arranged below the upper slider 2. The upper slider 2 and the lower slider 3 are fixedly connected by an intermediate limit rivet 7. The intermediate limit rivet 7 is arranged inside the slide rail limit groove 11. By using the design of the intermediate limit rivet 7 and the slide rail limit groove 11, the sliding limit position of the upper slider 2 can be defined. Preferably, the upper slider 2 and the lower slider 3 are further fixedly connected by a fixing rivet 8.

[0030] The left execution mechanism 5 has a left execution rod 51. The left execution rod 51 is arranged on the left side of the lower slider 3. When the lower slider 3 is moved leftward, the lower slider 3 drives the left execution rod 51 to move synchronously. In this embodiment, the number of the left execution mechanisms 5 is three, which are arranged in the front-rear direction. The front, middle, and rear parts of the lower slider 3 respectively correspond to the left execution rods 51 of the three left execution mechanisms 5, that is, the lower slider 3 can control the actions of the three left execution mechanisms 5 simultaneously. During the self-resetting process, powered by the spring as the energy storage component 4, the upper slider 2 can control the actions of the three left execution mechanisms 5 simultaneously.

[0031] The right execution mechanism 6 has a right execution rod 61. The right execution rod 61 is arranged on the right side of the lower slider 3. When the lower slider 3 is moved rightward, the lower slider 3 drives the right execution rod 61 to move synchronously. In this embodiment, the number of the right execution mechanisms 5 is three, which are arranged in the front-rear direction. The front, middle, and rear parts of the lower slider 3 respectively correspond to the right execution rods 61 of the three right execution mechanisms 6, that is, the lower slider 3 can control the actions of the three right execution mechanisms 6 simultaneously. During the self-resetting process, powered by the spring as the energy storage component 4, the upper slider 2 can control the actions of the three right execution mechanisms 5 simultaneously.

[0032] The spring energy storage component 4 is arranged in the built-in space of the slide rail. The spring energy storage component 4 has a left spring group 41 and a right spring group 42. The left spring group 41 and the right spring group 42 are respectively arranged on the left and right sides of the middle limit rivet 7. The left spring group 41 has a left longer spring 411 and a left shorter spring 412. The left ends of the left longer spring 411 and the left shorter spring 412 are both fixed ends. The right ends of the left longer spring 411 and the left shorter spring 412 are both movable ends. The left longer spring 411 is longer than the left shorter spring 412. The left ends of the left longer spring 411 and the left shorter spring 412 are both abutted against the left fixed pressing plate 12. The right end of the left longer spring 411 is abutted against the middle limit rivet 7. The right end of the left shorter spring 412 is suspended. If the operating handle 22 moves to the left, the upper slider 2 moves leftward. The upper slider 2 drives the middle limit rivet 7 to move leftward along the slide rail limit groove 11. At this time, the middle limit rivet 7 gradually compresses the left longer spring 411 to the left. When the middle limit rivet 7 abuts against the left shorter spring 412, in addition to compressing the left longer spring 411 to the left, the middle limit rivet 7 also compresses the left shorter spring 412 to the left until the middle limit rivet 7 reaches the left end of the slide rail limit groove 11. The right spring group 42 has a right longer spring 421 and a right shorter spring 422. The left end of the right longer spring 421 and the right end of the right shorter spring 422 are both fixed ends. The right end of the right longer spring 421 and the left end of the right shorter spring 422 are both movable ends. The right longer spring 421 is longer than the right shorter spring 422. The right ends of the right longer spring 421 and the right shorter spring 422 are both abutted against the right fixed pressing plate 13. The left end of the right longer spring 421 is abutted against the middle limit rivet 7. The left end of the right shorter spring 422 is suspended. If the operating handle 22 moves to the right, the upper slider 2 moves rightward. The upper slider 2 drives the middle limit rivet 7 to move rightward along the slide rail limit groove 11. At this time, the middle limit rivet 7 gradually compresses the right longer spring 421 to the right. When the middle limit rivet 7 abuts against the right shorter spring 422, in addition to compressing the right longer spring 421 to the right, the middle limit rivet 7 also compresses the right shorter spring 422 to the right until the middle limit rivet 7 reaches the right end of the slide rail limit groove 11. The design of the spring energy storage component 4 can make the curve of the operating force on the operating handle 22 change suddenly, improve the operating feel of the operation, effectively reduce the required operating energy, and there will be no dead point in the operation during the movement of the switch. The sudden change of the torque provides acceleration for the actuator, making the action efficiency of the mechanism higher and the synchronization better.

[0033] See also Figure 9 , X1+X2 is the maximum deformation of the left longer spring 411 during the pulling process, and X2 is the maximum deformation of the left shorter spring 412 during the pulling process. Assuming that the elastic coefficient of the left longer spring 411 is K1, and the elastic coefficient of the left shorter spring 412 is K2, if a single spring is used to replace the left longer spring 411 and the left shorter spring 412 to achieve the same function, and its elastic coefficient is set to K3, then the following relationship exists:

[0034] K1·X1+(K1+K2)·X2=K3·X3

[0035] From the above equation, we can see that K1 <K3,K2<K3,(K1+K2)> K3, the spring energy storage component 4 will have a sudden change in force curve at the position of X1 during the pulling process, which will enhance the operating feel during the pulling process. At the same time, during the entire pulling process, the work required by the spring energy storage component 4 is less than the work required by a single spring, which effectively reduces power consumption, avoids the phenomenon of failure of self-reset and jamming caused by failure of a single spring, and improves product reliability.

[0036] When the self-resetting pull structure is reset, the spring energy storage component 4 releases energy, and in the process of recovering from (X1+X2) to X1, the force decreases faster, resulting in a lower self-resetting speed of the upper slider 2 and the lower slider 3. In addition, the energy released by the spring energy storage component 4 is less than the energy released by a single spring, so the spring energy storage component 4 has less impact on the middle limit rivet 7 and less destructive force on parts, thereby extending the service life of the product to a certain extent.

[0037] The above only expresses the implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
