In the present invention, unless specified to the contrary, use of the terms of orientation such as "upper, lower, top, bottom" or the like, generally refer to the orientation as shown in the drawings, or to the component itself in a vertical, perpendicular, or gravitational orientation; likewise, for ease of understanding and description, "inner and outer" refer to the inner and outer relative to the profile of the components themselves, but the above directional words are not intended to limit the invention.

In order to solve the unstable problem of padlock locking among the prior art, this application provides a padlock.

As shown in fig. 1-10, the padlock of the present application includes a lock housing, a shackle 10, an extrusion 20, a locking assembly 30; the locking end of the shackle 10 is located in the lock housing and the shackle 10 is at least slidable in a first direction relative to the lock housing; at least a portion of the pressing member 20 is disposed within the housing, the pressing member 20 being capable of providing a pressing force to the strike 10 in at least a second direction, the first direction being disposed perpendicular to the second direction; the locking assembly 30 is disposed within the housing, the balls 36 of the locking assembly 30 locking or unlocking the strike 10, and the pressure member 20 maintaining the strike 10 locked to the locking assembly 30.

With the padlock of the above construction, locking of the padlock is achieved by the shackle 10 sliding in a first direction relative to the housing and engaging the locking assembly 30. When the padlock is locked, the shackle 10 is continuously locked by the locking assembly 30 in the lock housing, thereby achieving a continuous locked state of the padlock. When the padlock is in the locked state, the ball 36 in the locking assembly 30 is locked or unlocked with the lock beam 10, so that the padlock is kept in the locked state or enters the unlocked state. While the shackle 10 is still able to slide a small distance in the first direction when the padlock is in the locked condition with the balls 36 of the locking assembly 30 locked to the shackle 10. Therefore, by providing the pressing member 20, the pressing member 20 can provide the strike 10 with the pressing force in at least the second direction, so that the strike 10 can be prevented from sliding in the first direction. Therefore, the problem of relative sliding between the shackle 10 and the ball 36 is effectively solved, and the stability of the padlock is ensured.

Specifically, the balls of the presser 20 and the locking assembly 30 are located in different directions of the shackle 10, respectively. By such an arrangement, the pressing member 20 can keep the shackle 10 and the locking assembly 30 stationary when pressing the shackle 10, thereby preventing the locking assembly 30 from shaking while maintaining the locked state. Moreover, through the arrangement, the stress of the lock beam 10 can be uniform, the lock beam 10 is prevented from being deformed due to uneven stress, and the service performance and the precision of the padlock are effectively guaranteed.

Specifically, the shackle 10 has a recess 11 that engages with the pressing member 20, and an opening of the recess 11 extends in a first direction. By means of the arrangement, the matching position of the extrusion piece 20 and the lock beam 10 can be limited, the extrusion piece 20 is prevented from sliding when the lock beam 10 is extruded, and the stability of matching of the extrusion piece 20 and the lock beam 10 is effectively enhanced.

Specifically, both ends of the recess 11 in the first direction have first guide surfaces, which are inclined surfaces or arc surfaces. By providing the first guide surface as an inclined surface or a curved surface, the pressing member 20 can be caught in the concave portion 11 of the shackle 10 through the first guide surface and press the shackle 10 during the sliding of the shackle 10 in the first direction. Also, friction between the pressing member 20 and the shackle 10 can be reduced by this arrangement. Therefore, the service life of the extrusion 20 is effectively enhanced.

Specifically, the concave portion 11 is adapted to the shape of the pressing face of the pressing member 20. Through setting up like this, can guarantee that extruded piece 20 can be inseparabler with the contact of lock beam 10 when extrudeing lock beam 10 to increased extruded piece 20 and lock beam 10's area of contact, thereby made lock beam 10 atress more even, and then guaranteed extruded piece 20 effectively to the extrusion effect of lock beam 10.

Optionally, the pressing member 20 is a spring structure, and the spring structure includes a connecting section 21 and a pressing section 22 that are sequentially connected and formed by bending, the pressing section 22 extends along a first direction, and a surface of the pressing section 22 facing the side of the lock beam 10 is a pressing surface.

Optionally, the connection between the connecting section 21 and the pressing section 22 is in arc transition to form a second guiding surface, and the second guiding surface is an inclined surface or an arc surface.

Optionally, an end of the pressing section 22 away from the connecting section 21 has a third guiding surface, and the third guiding surface is an inclined surface or an arc surface.

The pressing member 20 is provided in a leaf spring structure so that when the pressing member 20 presses the shackle 10, the pressing member 20 is elastically deformed to some extent and prevents the shackle 10 from being inclined in the first direction. Moreover, as the padlock needs to be frequently switched between locking and unlocking in the using process, the extrusion part 20 needs good elastic performance, the extrusion part 20 is prevented from being invalid after being used for multiple times and being incapable of extruding the lock beam 10, and the extrusion part 20 is arranged into a spring plate structure, so that the durability of the extrusion part 20 can be improved. And the connecting section 21 and the extruding section 22 are arranged on the elastic sheet structure, so that the functions of each part of the elastic sheet structure can be distinguished.

Through setting up second spigot surface and third spigot surface into inclined plane or cambered surface, beginning to contact to the in-process that contacts completely at fore shaft 10 and extruded article 20 like this, not only can guarantee that extruded article 20 can provide the extrusion force to fore shaft 10, extruded article 20 passes through second spigot surface and third spigot surface when moreover can also and fixes a position, guarantees that the extrusion surface can cooperate completely with the concave part 11 of fore shaft 10.

In the locked state, the shackle 10 is manually pulled and the shackle 10 is restrained by the balls 36, but due to the play, the shackle 10 moves up a slight distance, passes through the position and the rounded corners of the pressing member 20, and after the pulling force provided by the hand is removed, the shackle 10 falls again and returns to the original locked state.

As shown in fig. 1 to 9, the locking assembly 30 includes a fixing seat 31, a support plate 32, a spring assembly 33, a trigger switch 34, and a plug assembly 35; the fixed seat 31 is arranged in the lock shell; the supporting plate 32 is arranged on the fixed seat 31 through a spring assembly 33; the trigger switch 34 is arranged on the fixed seat 31, and when the lock beam 10 presses the support plate 32, the support plate 32 moves to one side of the trigger switch 34 and triggers the trigger switch 34; the trigger switch 34 is signally connected to the plug assembly 35 to signal the plug assembly 35 to control the action of the balls 36 of the plug assembly 35 when the trigger switch 34 is triggered. Since the shackle 10 is still able to move a distance in the first direction when in the locked state, the arrangement is such that the shackle 10, when subjected to a force directed in the first direction and towards the support plate 32, can be triggered by contact with the support plate 32 and by pressing the support plate 32. After the triggering is completed, the supporting plate 32 can be reset under the action of the spring assembly 33, and the lock beam 10 can also be reset under the reset force of the supporting plate 32. And the trigger switch 34 can send a signal to the lock cylinder assembly 35 to control the action of the ball 36, so as to complete the locking or unlocking of the padlock.

One particular embodiment is when the padlock is in the locked position, the shackle 10 is in a resting position due to the action of the pressure member 20 and the support plate 32. When it is desired to unlock the padlock, the shackle 10 of the padlock is pressed, causing the shackle 10 to move in a first direction towards the support plate 32, thereby triggering the trigger switch 34 and waking up the bluetooth device in the padlock. After the padlock is pressed, the support plate 32 can be reset under the action of the spring assembly 33, so that the shackle 10 moves away from the support plate 32 in the first direction under the pushing force of the support plate 32. After waking up the bluetooth device, the user can send an instruction to the locking component 30 by operating the mobile phone APP to complete unlocking. After the locking assembly 30 is commanded, the motor in the locking assembly 30 drives the mechanism in the locking assembly 30 to unlock, i.e. the restriction of the ball 36 to the lock beam 10 is eliminated, and after the lock beam 10 is pulled manually, the ball 36 is squeezed by the lock beam 10 to contract, and the unlocking action is completed. Meanwhile, the locking assembly 30 may further have a lock cylinder module, and the main board MCU in the lock cylinder module records the padlock status as "unlocked".

When the padlock is to be locked, the shackle 10 is pressed by hand, the shackle 10 pushes the support plate 32 to trigger the trigger switch 34, the motor in the locking assembly 30 drives the mechanism in the locking assembly 30 to lock, and the main board MCU in the cylinder module locks the padlock.

Alternatively, the spring assembly 33 includes at least two springs, and at least one spring is supported on both sides of the support plate 32, respectively. Because the spring assembly 33 can provide the reset force for the support plate 32, the support plate 32 can be stressed uniformly by the arrangement, the support plate 32 can be prevented from being stressed unevenly to incline, and the reliability of the padlock is further ensured.

Specifically, the fixing base 31 includes a base body 311 and a guide plate 312. The seat body 311 has a positioning concave 315 for accommodating one end of the spring; both ends of the holder body 311 have guide plates 312 extending upward, one sides of the guide plates 312 opposite to each other have guide grooves 313, the spring is extended and contracted along the guide grooves 313, and both ends of the support plate 32 slide along the guide grooves 313. Through setting up location concave part 315, can fix the spring to can prevent that the spring from breaking away from pedestal 311, and then guarantee the normal work of padlock. And through set up guide way 313 at the both ends of pedestal 311, can prevent that the spring from producing the skew when the spring is to backup pad 32 effect to prevent backup pad 32 unbalance, and then guaranteed effectively that the lock beam 10 can carry out normal cooperation with locking Assembly 30, guarantee the normal use of padlock.

Specifically, one end of the guide slot 313 away from the holder body 311 is provided with a stopping ledge 314, and the stopping ledge 314 is located on the slot wall of the guide slot 313 to prevent the support plate 32 from being pulled out of the guide slot 313. Through setting up like this, the spring in spring unit 33 resets the in-process to backup pad 32, can prevent that backup pad 32 from deviating from pedestal 311 because of inertial reason to realize the limiting displacement to backup pad 32 through guide way 313, guaranteed the precision of padlock effectively.

Specifically, the middle of the seat body 311 has a mounting groove, and the trigger switch 34 is disposed in the mounting groove. The arrangement can trigger the trigger switch 34 through the support plate 32 when the lock beam 10 acts, thereby ensuring that the whole locking or unlocking action is completed smoothly.

As shown in fig. 1 to 9, the shackle 10 further has a sliding slot 12 extending along a first direction, and the padlock further includes a limiting pin 40, wherein the limiting pin 40 is fixed relative to the lock housing and one end of the limiting pin extends into the sliding slot 12; the locking end of the lock beam 10 is further provided with a stop flange 13 matched with the stop of the limit pin 40, and the stop flange 13 is positioned between the limit pin 40 and the extrusion piece 20 to prevent the lock beam 10 from over-position movement. Another specific embodiment is that after the padlock is unlocked, when the lock beam 10 is stretched to the outside of the lock case along the first direction, the lock beam 10 is limited by the limiting pin 40 after being stretched for a certain distance, and at this time, the ball 36 is completely retracted as the locking assembly 30, that is, the padlock is in the unlocking state, and after the unlocking is completed, the lock cylinder module enters the low-power operation.

During use of the padlock, the role of the expression member 20 is mainly two: firstly, the shaking of the lock beam 10 is known, so that the direct contact between the groove where the lock beam 10 is matched with the ball 36 and the ball 36 is avoided, and the resistance of the motor is reduced; secondly, when the lock beam 10 is changed from the unlocking state to the locking state, the lock beam 10 is in frictional contact with the extrusion piece 20 in the process of moving towards the support plate 32 along the first direction, so that people feel the gear feeling of inserting the lock beam 10 in place.
