[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] like Figure 1-Figure 5 As shown, the embodiment of the present application provides a safety mechanism, including an unlocking member 2, a limiting member 4, a sensing member and a driving member 5. The safety mechanism constitutes a part of the locking device, which is used to keep the locking device locked to prevent the locking device from being directly unlocked by external force.

[0033] The unlocking member 2 is used to unlock the locking device. The locking device can be unlocked by driving the unlocking member 2 to move along the unlocking path. Specifically, when the unlocking member 2 is in the locked position, the locking device is in the locked state. When the unlocking member 2 is in the unlocking position, the locking device is in the unlocked state. The above-mentioned unlocking path is the path of the unlocking member 2 moving from the locked position to the unlocked position.

[0034] The limiting member 4 can move to the unlocking path of the unlocking member 2 to block the unlocking member 2 from moving from the locked position to the unlocking position, thereby limiting the unlocking member 2 from unlocking the locking device, and the limiting member 4 can move outside the unlocking path of the unlocking member 2 to cancel the position limit of the unlocking member 2, thereby allowing the unlocking member 2 to unlock the locking device. Specifically, the limiting member 4 can move between the safety position and the first position, the safety position is on the unlocking path of the unlocking member 2, and the first position is outside the unlocking path of the unlocking member 2.

[0035] The sensing member is used to sense the limiting state of the limiting member 4 on the unlocking member 2, and the limiting state can be the state when the limiting member 4 is in the safety position or the state when the limiting member 4 is in the first position, so as to judge whether the limiting member 4 limits the unlocking member 2. For example, the sensing member is set as a photoelectric sensor to sense the position information of the limiting member 4, or the sensing member is set as a distance sensor to obtain the distance information between the limiting member 4 and the unlocking member 2.

[0036] The driving member 5 is connected to the limiting member 4 and is used to drive the limiting member 4 to move between the safety position and the first position. Moreover, the driving member 5 is in communication connection with the sensing member so that the driving member 5 can drive the limiting member 4 to move according to the sensing value of the sensing member. When it is necessary to keep the locking device locked, if the sensing member senses that the limiting member 4 is not in the safety position, the driving member 5 can drive the limiting member 4 to move to the safety position (on the unlocking path of the unlocking member 2) to prevent the unlocking member 2 from moving along the unlocking path; when the locking device needs to be unlocked, if the sensing member senses that the limiting member 4 is in the safety position, the driving member 5 can drive the limiting member 4 to move to the first position (outside the unlocking path of the unlocking member 2) to allow the unlocking member 2 to move along the unlocking path.

[0037] With such arrangement, the safety mechanism has a simple structure and is stable and reliable. Through the design of the sensing element and the driving element 5, the opening and closing of the safety mechanism can be automatically controlled according to actual needs. The operation is simple, which is beneficial to improving the unlocking efficiency of the locking device and can avoid safety hazards caused by forgetting to open the safety mechanism.

[0038] In some embodiments, the insurance mechanism includes an operating member 3, which is used for manual operation by personnel to facilitate manual opening and manual closing of the insurance mechanism. The operating member 3 is connected to the limiting member 4. Under the action of external force, the operating member 3 can drive the limiting member 4 to move from the unlocking path of the unlocking member 2 to the outside of the unlocking path, so that the limiting member 4 cancels the limit on the unlocking member 2, thereby allowing the unlocking member 2 to unlock the locking device. In this way, the insurance mechanism is a manual-automatic integrated form. In an emergency, the insurance mechanism can be opened and closed manually to facilitate opening the door of the cargo plane and improve the efficiency of emergency evacuation. Moreover, in the case of forgetting to open the insurance mechanism, the driving member 5 can automatically open the insurance mechanism.

[0039] It should be noted that, in the process of the operating member 3 driving the limiting member 4 to move, the limiting member 4 moves between the safety position and the second position, the safety position is on the unlocking path of the unlocking member 2, and the second position is outside the unlocking path of the unlocking member 2. The first position and the second position can be the same position or different positions, that is, the directions in which the driving member 5 and the operating member 3 drive the limiting member 4 to move can be consistent or inconsistent.

[0040] The safety mechanism includes an elastic member, which is connected to the limiter 4 and can drive the limiter 4 to move from the unlocking path outside the unlocking path of the unlocking member 2 to the unlocking path to achieve automatic safety reset of the safety mechanism. Specifically, the elastic member can be set as a spring structure and connected between the driving member 5 and the limiter 4. Of course, in order to keep the elastic force direction of the spring structure stable, a guide structure can also be set between the driving member 5 and the limiter 4. Under the action of the guide structure, the limiter 4 can stably move between the safety position and the second position.

[0041] In the process of manually releasing the safety, the personnel needs to manually apply force to the operating member 3 continuously, and when overcoming the elastic force of the elastic member, the limiting member 4 moves to the outside of the unlocking path of the unlocking member 2. At this time, the unlocking member 2 moves from the locked position to the unlocked position, and the locking device can be unlocked; after the locking device is unlocked, the unlocking member 2 returns to the locked position under the action of the return spring, and the personnel cancels the force applied to the operating member 3. Under the elastic action of the elastic member, the limiting member 4 returns to the safety position (on the unlocking path of the unlocking member 2). In this way, through the design of the elastic member, the safety of manually releasing the safety can be improved, and the potential safety hazards caused by accidental touch can be avoided.

[0042] like Figure 1-3 As shown, the safety mechanism includes a housing 1 for carrying other components of the safety mechanism. Among them, the driving member 5 and the unlocking member 2 are fixed inside the housing 1, and the limiting member 4 is connected between the driving member 5 and the operating member 3, for example, the limiting member 4 is connected to the driving member 5 through an elastic member, and the operating member 3 is exposed outside the housing 1, for example, an opening for the operating member 3 to extend is provided on the housing 1. Driven by the operating member 3, the limiting member 4 can approach and move away from the driving member 5, so that the operating member 3 and the limiting member 4 can be elastically displaced relative to the housing 1, thereby realizing the manual release of the safety mechanism. In this way, the driving member 5 and the operating member 3 are respectively located on both sides of the limiting member 4 and loaded in the housing 1, and the structural integrity is good, which is conducive to automatic and manual control.

[0043] Of course, in other solutions, the elastic member can be arranged between the driving member 5 and the housing 1, and by applying force to the operating member 3, the limiting member 4 and the driving member 5 can be driven to move relative to the housing 1 together.

[0044] In some preferred embodiments, the unlocking member 2 can unlock the locking device by rotating along the first axis. Specifically, the unlocking member 2 is configured as a connecting rod, and the first end of the connecting rod is connected to the housing 1 so that the connecting rod can rotate relative to the housing 1 along the first axis. A pull ring 8 is provided on the outside of the housing 1, and the pull ring 8 is connected to a position of the unlocking member 2 away from the first end (such as the middle or second end of the unlocking member 2) through a pull rod 7. The pull ring 8 can drive the unlocking member 2 to rotate relative to the housing 1 along the first axis to unlock the locking device, which is easy to operate, saves time and effort, and is conducive to improving the efficiency of manual unlocking.

[0045] The driving member 5 drives the limiting member 4 to rotate along the second axis to move closer to and away from the unlocking member 2, thereby moving between the safety position and the first position. Specifically, the driving member 5 is configured as a motor, the limiting member 4 is configured as a strip, the first end of the limiting member 4 is connected to the output shaft of the motor, and the second end of the limiting member 4 is suspended. The driving member 5 can drive the second end of the limiting member 4 to move between the safety position and the first position, and the axis of the output shaft is the second axis.

[0046] The operating member 3 drives the limiting member 4 to move along the first direction, so that the limiting member 4 moves between the safety position and the second position (i.e., the unlocking path of the unlocking member 2). For example, a guiding structure is arranged between the limiting member 4 and the driving member 5, and the operating member 3 can drive the limiting member 4 to move along the guiding direction of the wire structure, and the guiding direction of the guiding structure is the first direction.

[0047] The first axis, the second axis and the first direction meet the parallel condition, so that the directions in which the driving member 5 and the operating member 3 drive the limiting member 4 to release the safety are perpendicular, and the power transmission between the driving member 5 and the limiting member 4 will not interfere with the power transmission between the operating member 3 and the limiting member 4, and the structure is stable and reliable. Specifically, the first axis and the second axis are arranged at intervals to avoid interference between the positions of the unlocking member 2 and the limiting member 4, so that the limiting member 4 can block the unlocking member 2.

[0048] It can be understood that when the driving member 5 drives the limiting member 3 to rotate to the first position, although it is still on the rotation plane of the unlocking member 2, it is not on the unlocking path of the unlocking member 2, that is, when the unlocking member 2 rotates from the locked position to the unlocking position, it will not be blocked by the limiting member 4.

[0049] like Figure 4 As shown, the operating member 3 is provided with an identification portion 9, which is arranged on the side of the operating member 3 away from the limiting member 4 so as to be exposed to the housing 1. The identification portion 9 can show the limiting state of the limiting member 4 on the unlocking member 2, which is helpful for personnel to judge whether the insurance mechanism is opened. For example, the identification portion 9 is set as an arrow-shaped groove. Under the drive of the driving member 5, the operating member 3 rotates with the limiting member 4, and the direction of the arrow-shaped groove is different, and then judge whether the insurance mechanism is opened.

[0050] The position-limiting member 4 is arranged in a strip shape, and has a first end and a second end. The first end of the position-limiting member 4 is connected to the output end of the driving member 5, and the second end is suspended. A magnetic member 6 (such as a magnet) is arranged at the second end of the position-limiting member 4, and the sensing member is used to sense the magnetic strength at the position, and obtain the position information of the position-limiting member 4 according to the magnitude of the magnetic field strength sensed by the sensing member. For example, the sensing member is arranged as a Hall sensor or a magnetic sensor, and the sensing member is arranged on the housing 1 and close to the safety position. When the second end (magnetic member 6) of the position-limiting member 4 is in the safety position, the magnetic field strength sensed by the sensing member is relatively large, and when the second end (magnetic member 6) of the position-limiting member 4 is in the first position, the magnetic field strength sensed by the sensing member is relatively small.

[0051] A limiting groove is provided on the unlocking member 2. When the limiting member 4 is in the safety position, the limiting member 4 can be partially embedded in the limiting groove. In this way, the contact position between the limiting member 4 and the unlocking member 2 can be prevented from slipping, causing the problem of insurance failure.

[0052] The embodiment of the present application provides a locking device, including the safety mechanism in the above embodiment. Such a configuration is simple in structure, stable and reliable; through the design of the sensing member and the driving member 5, the opening and closing of the safety mechanism can be automatically controlled according to actual needs, the operation is simple, which is conducive to improving the unlocking efficiency of the locking device and can avoid the potential safety hazards caused by forgetting to open the safety mechanism.

[0053] It should be noted that "parallel" in this application means that one direction is parallel to another direction, but it is not limited to the absolute parallelism of the two.
