DETAILED DESCRIPTION

[0019] Reference Figure 1 and Figure 2The application discloses a cockpit locking structure, which comprises a slide rail 3, an electromagnet 4 and a seat mounting plate 1 for mounting a seat, wherein the seat mounting plate 1 is connected with a locking plate 7, the electromagnet 4 is fixedly arranged at a position where the seat needs to be locked, and is used for adsorbing the locking plate 7. In actual application, two slide rails 3 are arranged and fixedly connected on two sides of a support beam, the seat mounting plate 1 is slidably arranged on the slide rails 3 through a sliding block 14 (it is easily understood that a connecting block 13 can be further connected between the sliding block 14 and the seat mounting plate 1 for the convenience of connection), and a seat (not shown in the figure) is mounted on the seat mounting plate 1 and slides along the slide rails 3 together with the seat mounting plate 1. Figure 2 and Figure 3 The electromagnet 4 is mounted in an electromagnet mounting seat 5 and is connected to the support beam through a connecting seat 6. The electromagnet 4 is always in a power-on state. After the seat is slid to a position, the electromagnet 4 adsorbs the locking plate 7, so that the position of the seat is locked. When unlocking is needed, the electromagnet 4 is powered off. In addition, the electromagnet 4 can be controlled through a self-resetting torsion switch (not shown in the figure), and the torsion switch is mounted beside a seat armrest, so that operation is facilitated.

[0020] As an alternative, the locking plate 7 and the electromagnet 4 are arranged below the seat mounting plate 1. Further, a cockpit bottom plate 2 can be further arranged on the top of the support beam (it is easily understood that a sliding groove for avoiding the sliding block 14 is arranged on the cockpit bottom plate 2), and the locking plate 7 and the electromagnet 4 are hidden below the cockpit bottom plate 2, so that the visual environment inside the cockpit is not changed.

[0021] In the embodiment, the locking plate 7 and the seat mounting plate 1 are connected through a connecting assembly, referring to Figure 4 and Figure 5 The connecting assembly comprises a locking plate mounting seat 8, a connecting rod 9 and a universal bearing 12. The locking plate mounting seat 8 is fixedly connected to the bottom of the seat mounting plate 1. One end of the connecting rod 9 is connected to the locking plate mounting seat 8. The locking plate 7 is provided with a bearing hole, the universal bearing 12 is embedded in the bearing hole, the other end of the connecting rod 9 is arranged in the universal bearing 12, and the position of the locking plate 7 in the axial direction of the connecting rod 9 is fixed.

[0022] It is worth noting that the universal bearing 12 is also called a joint bearing, which is a kind of spherical sliding bearing. The outer ring and the inner ring are in contact through a spherical surface, and the inner ring can rotate and swing in any direction. On this basis, the above arrangement makes the locking plate 7 have a rotational degree of freedom and can rotate in any direction. When the locking plate 7 is adsorbed by the electromagnet, the direction of the locking plate 7 can be corrected, so that the locking plate 7 and the adsorption surface of the electromagnet are in surface-to-surface fitting adsorption, and the locking is more reliable.

[0023] As an alternative, the connecting rod 9 in this embodiment is a bolt, the bolt rod is connected to the lock plate mounting seat 8 through a thread at the end away from the head, further, the bolt is connected with a lock nut 10 on both sides of the lock plate mounting seat 8 to ensure reliable connection. In this embodiment, the position of the lock plate 7 in the axial direction of the connecting rod 9 is fixed as follows, one side of the lock plate 7 is limited by the head of the bolt, the other side of the lock plate 7 is limited by a limiting nut 11, and the limiting nut 11 is connected with the bolt. It should be understood that in other embodiments, the connecting rod 9 can of course also be other structures, for example, a light rod, one end of which is welded and fixed to the lock plate mounting seat 8, and the other end is inserted into the universal bearing 12, and then the lock plate 7 is fixed in the axial direction of the connecting rod 9 by means of a snap spring or the like.

[0024] In this embodiment, the lock plate mounting seat 8 is provided with a limiting frame 801 for limiting the rotation angle of the lock plate 7 around the connecting rod 9 within a target range. It should be noted that due to the action of the universal bearing 12, the limiting plate can also rotate around the connecting rod 9, and if the rotation angle is improper, the contact area between the lock plate 7 and the electromagnet 4 will be reduced, affecting the adsorption effect. The setting of the limiting frame 801 limits the excessive rotation of the lock plate 7, solving the technical problem. The specific value of the above-mentioned "target range" is not limited, as long as the limiting plate can be reliably adsorbed with the electromagnet 4 after rotation. In addition, it is easy to understand that the limiting frame 801 is shown as a frame structure with one side open in the drawings, and other structures that can ensure that at least one side of the limiting plate has a frame edge and can limit rotation can also be used.

[0025] Reference Figure 2 In this embodiment, the slide rail 3 is fixedly provided with a damping device 15, which absorbs and buffers during the process that the lock plate 7 gradually contacts the electromagnet 4, slows down the impact, avoids collision between the electromagnet 4 and the lock plate 7, and improves safety and reliability. In practical application, the damping device 15 is opposite to the sliding block 14, and during the process that the lock plate 7 gradually contacts the electromagnet 4, the sliding block 14 also gradually presses the damping device 15. As a kind of rotation, the damping device 15 can select a spring buffer, and of course, a hydraulic buffer, an air pressure buffer or a rubber buffer and other devices that can have the same effect can also be selected.

[0026] In addition, it should be noted that when some screws or nuts in the axial direction of the seat sliding direction (such as the connecting screw of the electromagnet 4, the lock nut 10, etc.) are loose, a certain play will exist in the connected parts. Due to the existence of the damping device 15, after the seat is in place, the counterforce provided by the compressed damping device 15 can compensate for the play.

[0027] The above merely is preferred embodiment of the present utility model, and is not for limiting the present utility model, for the person skilled in the art, the present utility model can have various changes and changes. Any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
