[0034] The following is combined with Figures 1 to 7 , and further illustrate the technical solution of the utility model through specific implementation methods.

[0035] The embodiment of the present application provides an unlocking device 100 for unlocking a locking element 200. Figure 1 to Figure 7 As shown, the unlocking device 100 includes: a base plate 180, an unlocking component 120 and a driving component 110. The driving component 110 is fixedly connected to the base plate 180, and the driving component 110 is fixedly connected to the unlocking component 120, and is used to provide a driving force for the unlocking component 120 along a third direction Z. The unlocking component 120 includes two sliding components 121, and the two sliding components 121 are arranged along a first direction X, and each of the sliding components 121 is connected to an output end of the driving component 110; under the drive of the driving component 110, the sliding components 121 are in contact with the surface of the upper lock body 201 of the locking element 200 and move away from each other along the first direction X, so that the lock hook 203 of the locking element 200 is ejected, and the locking element 200 is unlocked. As shown Figure 5 The circle A in the figure indicates that the lock hook 203 is not unlocked. Figure 5 The circle B in the figure represents the unlocked state of the lock hook 203. The first direction X is perpendicular to the third direction Z. To further illustrate the unlocking device 100 of the present application, a rectangular coordinate system is established with the third direction as the Z axis, the first direction as the X axis, and the second direction perpendicular to the first direction and the third direction as the Y axis.

[0036] The unlocking device 100 provided in the embodiment of the present application converts the driving force of the driving component 110 along the third direction Z into the driving force of the sliding component 121 moving away from each other along the third direction Z through the setting of the unlocking component 120 and the driving component 110, so that the sliding component 121 can move in contact with the surface of the upper lock body 201 of the locking element 200 and move away from each other along the first direction X, and the lock hook 203 of the locking element 200 is ejected, the locking element 200 is unlocked, and the locking element 200 is automatically unlocked, thereby reducing labor costs and facilitating wide application.

[0037] In a possible implementation, Figure 1-2 As shown, the sliding assembly 121 includes a roller 1211 and a bearing 1212, the bearing 1212 is connected to the output end of the driving assembly 110, the roller 1211 is sleeved outside the bearing 1212, and is rotatably connected to the bearing 1212, and the roller 1211 is used to move in contact with the surface of the upper lock body 201 of the locking element 200 and to bounce the lock hook 203. In this way, by using the roller 1211 and the bearing 1212 as the sliding assembly 121, the sliding friction between the sliding assembly 121 and the locking element 200 can be converted into rolling friction, thereby reducing the damage to the locking element 200 caused by friction and extending the service life of the device.

[0038] In a possible implementation, Figure 1 to Figure 5 As shown, the unlocking assembly 120 further includes two first connecting assemblies 130. One end of each of the first connecting assemblies 130 is connected to the output end of the driving assembly 110, and the other end is connected to the sliding assembly 121. The first connecting assembly 130 drives the sliding assembly 121 to be rotatably connected to the output end of the driving assembly 110. By providing the first connecting assembly 130, the sliding assembly 121 is rotatably connected to the output end, and the roller 1211 can also rotate relative to the output end when rolling on the surface of the locking element 200, so that the roller 1211 can better stick to the fixed position of the lock hook 203 to unlock, and the unlocking force is more stably applied to the lock hook 203, thereby improving the success rate of unlocking.

[0039] Furthermore, if Figure 1-2As shown, the output end of the driving component 110 is provided with a third connecting member 112, and the two ends of the third connecting member 112 are respectively connected to the two connecting components. The first connecting component 130 includes: a first connecting member 131, a first rotating shaft 132 and a second connecting member 133. Among them, the first connecting member 131 is connected to the output end of the driving component 110, one end of the second connecting member 133 is rotatably connected to the first connecting member 131, and the other end is connected to the sliding component 121; the first connecting member 131 is provided with a first through hole, and the second connecting member 133 is provided with a second through hole, the first through hole and the second through hole are connected along the second direction Y to form a first rotating shaft 132 through hole, and the first rotating shaft 132 is sleeved in the first rotating shaft 132 through hole; the second connecting member 133 is provided with a third through hole, and the bearing 1212 is sleeved in the third through hole, and the second direction Y is perpendicular to the first direction X and the third direction Z.

[0040] Furthermore, if Figure 2 As shown, a limiting structure 134 is also provided on the first connecting member 131, and the limiting structure 134 is used to limit the rotation of the sliding assembly 121 relative to the first connecting member 130. The limiting structure 134 limits the rotation of the sliding assembly 121 along the third direction Z. Here, the limiting structure 134 is an opening slightly wider than the width of the second connecting member 133 opened on the plate, and the height of the opening along the third direction Z is the upper limit height of the limiting structure 134 to stop the rotation.

[0041] Furthermore, the limiting structure 134 and the first connecting member 131 may be integrally formed, which can improve the stability of the limiting structure 134. In a feasible implementation, the limiting structure 134 may also be different from Figure 2 The structure on the drive assembly 110 is an independent limit block, which is independently connected to the output end of the drive assembly 110 and is not connected to the second connecting member 133. In a feasible embodiment, the limit block can also be a protrusion set on the second connecting member 133. When the limit block abuts against the output end of the drive assembly 110, such as the third connecting member 112, the rotation limit, i.e., the anti-rotation effect, is achieved. In this way, the limit block set on the second connecting member 133 can also be integrally formed with the second connecting member 133.

[0042] In a possible implementation, Figure 2As shown, the unlocking assembly 120 further includes a first elastic assembly 122, which is disposed between the output end of the driving assembly 110 and the sliding assembly 121. The first elastic assembly 122 is used to buffer the impact force when the driving assembly 110 drives the sliding assembly 121. Specifically, the output end of the driving assembly 110 is further provided with two fourth connecting members 113 disposed along the third direction Z, one end of the two fourth connecting members 113 is respectively connected to the two ends of the third connecting member 112, and the other end is connected to the second connecting member 133. The first elastic assembly 122 is sleeved on the fourth connecting member 113, which can transmit the driving force of the driving assembly 110 on the one hand, and guide the first elastic assembly 122 on the other hand.

[0043] In a feasible implementation, the unlocking device 100 further includes a suction cup assembly 140, the suction cup assembly 140 is connected to the base plate 180, the suction cup assembly 140 is disposed between the two sliding assemblies 121, and the suction cup assembly 140 is used to absorb the unlocked upper lock body 201. The suction cup assembly 140 is provided so that the upper lock body 201 can be removed after unlocking, thereby facilitating the removal of the product locked by the locking element 200.

[0044] Furthermore, if Figure 3 As shown, the suction cup assembly 140 includes a suction head 141 and a suction head connector 142. The suction head 141 is arranged above the suction head connector 142 along the third direction Z. The suction head connector 142 is connected to the base plate 180. When the base plate 180 driving assembly 110 drives the base plate 180 to approach the locking element 200 along the third direction Z, the suction head 141 approaches the upper lock body 201. The suction head 141 can also be connected to the cylinder assembly, and when it approaches the upper lock body 201, negative pressure is generated to adsorb the upper lock body 201.

[0045] In a possible implementation, Figure 4 As shown, the locking element 200 further includes a third elastic element 204. When the locking element 200 is in a locked state, the third elastic element 204 is in a compressed state. When the locking element 200 is in an unlocked state, the third elastic element 204 changes from a compressed state to a normal state, and the upper lock body 201 is ejected to unlock the element. Thus, when the locking element 200 is unlocked, the upper lock body 201 needs to be pressed to prevent the upper lock body 201 from ejecting after the lock hook 203 is ejected. Figure 3As shown, the unlocking device 100 also includes a pressure head 151 assembly 150. The pressure head 151 assembly 150 is connected to the substrate 180, and the pressure head 151 assembly 150 is used to apply pressure to the upper lock body 201 of the locking element 200 along the third direction Z. Further, the pressure head 151 assembly 150 includes a pressure head 151, two pressure head connectors 152 and two second elastic components. The pressure head connector 152 is fixedly connected to the substrate 180 at one end along the third direction Z, and is connected to the pressure head 151 at the other end, and the second elastic element 153 is sleeved on the pressure head connector 152. The fixed connection or connection mentioned here can be connected by fasteners such as nuts, etc., or it can be connected by threads by opening corresponding threads and threaded holes on the connector and the substrate 180. The pressure head 151 has a through hole for accommodating part of the suction head 141 assembly. The second elastic component is used to buffer the impact force when the pressing head 151 approaches the upper locking body 201 .

[0046] In a possible implementation, Figure 1 and Figure 7 As shown, the unlocking device 100 also includes a positioning assembly 160. The positioning assembly 160 is connected to the substrate 180 and is used to position the unlocking device 100 in the first direction X and the second direction Y. Further, the positioning assembly 160 may include a first direction positioning mechanism 161 and a second positioning direction mechanism. Among them, the first direction positioning mechanism 161 is used to position the substrate 180 along the first direction X. Specifically, the first direction positioning mechanism 161 may include a first positioning plate 1611, a first sliding plate 1612, a first positioning screw 1613 and a first positioning nut 1614. Among them, the first positioning plate 1611 is fixed to the substrate 180 along the third direction Z, the first sliding plate 1612 is used to be fixed to other devices, and the first positioning screw 1613 is penetrated in the first positioning plate 1611 along the first direction X and is connected to the first sliding plate 1612. The first positioning nut 1614 is sleeved outside the first positioning screw 1613, and is used to adjust and fix the position of the first positioning plate 1611 driven by the first screw relative to the first sliding plate 1612 in the first direction X. The structure of the second direction positioning mechanism 162 is similar to that of the first direction positioning mechanism 161, and will not be described in detail here. By setting the positioning assembly 160, the unlocking device 100 can be fixed to other devices, and the positioning adjustment in the first direction X and the second direction Y can be performed, so as to facilitate more accurate unlocking of the locking element 200 and improve the unlocking success rate.

[0047] In a possible implementation, Figure 1As shown, the unlocking device 100 further includes a sensor 170 for detecting the adsorption state of the suction cup assembly 140. Further, the signal emitted by the sensor 170 is arranged along the first direction X, and the signal emission end of the sensor 170 is arranged below the pressure head 151.

[0048] In a possible implementation, Figure 6 As shown, the sliding assembly may not be a roller and bearing 1212 structure, for example, it may be a wedge assembly 123. The wedge assembly 123 is connected to the output end of the driving assembly 110, and the inclined surface of the wedge assembly 123 fits the surface of the upper lock body 201 of the buckle element. The wedge assembly 123 slides along the surface of the upper lock body 201 of the buckle element 200 under the drive of the driving assembly 110, and moves away from each other, and can also bounce the lock hook 203 to complete the unlocking.

[0049] In a feasible implementation, the driving device 111 of the driving assembly 110 may be a pneumatic cylinder, a hydraulic cylinder, an electric push rod, or a linear motor.
