In order to avoid the false unlocking of the cover lock, the invention also comprises a safety baffle 4, and the driving motor is in transmission connection with the safety baffle through a transmission mechanism, so that the safety baffle has a locking state for locking the lock tongue and an unlocking state for releasing the lock tongue. When the front cover is in the locking state, the safety baffle is in the locking state of locking the spring bolt, and the driving motor can not drive the spring bolt action this moment to ensure that the spring bolt is positioned at the locking position. When the front cover needs to be opened by opening the cover lock, the unlocking key of the remote control key can be pressed once, at the moment, the driving motor rotates forwards for an angle, and the transmission mechanism drives the safety baffle to be switched from the locking state to the unlocking state so as to release the locking of the lock tongue; then pressing the unlocking key of the remote control key once again, driving the motor to continue to rotate in the forward direction, keeping the safety baffle still, switching the lock tongue from the locking position to the releasing position, and separating the lock catch and the lock tongue to conveniently open the front machine cover upwards; when the front machine cover is closed and the machine cover lock needs to be closed, the locking key of the remote control key is pressed, the driving motor reversely rotates and resets, the lock tongue resets from the release position to the locking position through the transmission mechanism to restore the locking of the lock catch, and the safety baffle resets from the unlocking state to the locking state through the transmission mechanism to restore the locking of the lock tongue.
As a preferred scheme, the transmission mechanism comprises two steel wire drawing wires 5 which respectively control the lock tongue and the safety baffle, and the steel wire drawing wires can adopt steel wires similar to those used for braking a bicycle wire. The bolt is provided with a first reset spring (not shown in the figure), and the safety baffle is provided with a second reset spring (not shown in the figure). When the driving motor rotates forwards, the safety baffle can be driven by the steel wire pull wire to rotate from a locking state to an unlocking state so as to release the locking of the lock tongue; or the lock tongue is driven to rotate to the release position from the locking position through the steel wire pull wire. When the driving motor rotates reversely, a steel wire pull wire for controlling the lock tongue is released firstly, and at the moment, the first return spring enables the lock tongue to reset and rotate to a locking position from a releasing position; and then the steel wire pull wire for controlling the safety baffle is released, and at the moment, the second return spring enables the safety baffle to be reset and rotated from the unlocking state to the locking state.
It can be understood that the first return spring and the second return spring are both torsional springs to drive the bolt and the safety shield to rotate and reset.
Furthermore, the invention also comprises a fixed plate 6 vertically arranged in the front cabin, the bolt and the safety baffle are rotatably connected on the fixed plate, and a V-shaped opening 61 is arranged on the upper side edge of the fixed plate. The hasp includes two vertical linkage segments, an organic whole and just is located the locking section of V-arrangement opening bottom between two linkage segment lower extremes to make the hasp be upright U-shaped, the upper end of two linkage segments of hasp is connected on the machine cover in the front. In addition, the lock tongue is of a sheet structure and comprises a locking opening 22 and a convex locking end 21, the orientation of the locking opening inclines from bottom to top to one side, when the lock tongue is in a locking position, the locking opening and the V-shaped opening are overlapped with each other to form an annular common area, and an included angle of 30-90 degrees is formed between the directions of the locking opening and the V-shaped opening.
Thus, when the lock tongue is in the locking position and the safety shield is in the locking state, the locking section of the lock catch is located in the common area of the locking opening and the V-shaped opening and is reliably locked, and the safety shield abuts against the front side of the locking end of the lock tongue in the forward rotation direction. That is, the lock tongue at this time cannot rotate in the forward direction to release the lock of the buckle; when the driving motor enables the safety baffle to rotate from a locking state to an unlocking state, the safety baffle is separated from the front side of the locking end in the forward rotation direction, and therefore the locking of the lock tongue is released; the bolt at this moment can rotate to the release position by the locking position, and at this in-process, the locking section of hasp can be followed and upwards slided out in the locking opening.
Further, the lower side of the locking opening includes a locking section 221 disposed opposite to the upper side, and a support section 222 formed by extending the locking section outward, so that the lower side is longer than the upper side. Thus, when the lock tongue is in the locking position, the locking section of the lock catch is positioned between the clamping sections on the upper side and the lower side; when the spring bolt rotated to the release position by the locking position, the locking section of hasp then slided to the support section by the screens section, and the support section of spring bolt can continue to form the support of vertical direction to the hasp this moment, and the locking section of hasp then can upwards cross locking open-ended last side, and then upwards roll-off in locking opening and the V-arrangement opening.
As another preferred scheme, as shown in fig. 2 and fig. 3, the transmission mechanism includes a base 7, the driving motor 1 is a stepping motor disposed on the base, a motor shaft of the driving motor is coaxially connected with one end of a lead screw 11, and the other end of the lead screw is supported on a bearing seat 71 on the base. The screw rod is connected with a front driving sleeve and a rear driving sleeve 8 in a threaded mode, the rear end of each driving sleeve is a driving end 81, and the front end of each driving sleeve is a control end 82.
Note that, one end of the bearing housing is referred to as a front end, and the other end of the drive motor is referred to as a rear end.
Further, an axially extending axial slide groove 821 is provided outside the control end of the drive sleeve, a circumferential slide groove 822 extending in the circumferential direction of the drive sleeve is connected to the rear end of the axial slide groove, and the axial slide groove and the circumferential slide groove are connected to each other in an L-shape. Two guide sliding blocks 9 are arranged on the base, the upper end of the first guide sliding block at the back is positioned at the front end of the axial sliding groove of the first driving sleeve at the back, and the upper end of the second guide sliding block at the front is positioned at the tail end of the circumferential sliding groove of the second driving sleeve at the front.
In addition, a steel wire pull wire for controlling the bolt is wound on the driving end of the first driving sleeve, and a steel wire pull wire for controlling the safety baffle is wound on the driving end of the second driving sleeve. When the unlocking key is pressed once and the driving motor drives the screw rod to rotate forwards, because the upper end of the second guide sliding block is positioned at the tail end of the circumferential sliding groove of the second driving sleeve, the second guide sliding block prevents the second driving sleeve from moving axially, the second driving sleeve synchronously rotates under the driving of the screw rod, correspondingly, the second guide sliding block slides from the tail end to the starting end connected with the axial sliding groove in the circumferential sliding groove of the second driving sleeve, the second guide sliding block is aligned with the axial sliding groove of the second driving sleeve, and the driving end of the second driving sleeve winds a steel wire stay wire for controlling the safety baffle, so that the safety baffle rotates from the locking state to the unlocking state. Meanwhile, the upper end of the first guide sliding block is located at the front end of the axial sliding groove of the first driving sleeve, so that the first guide sliding block prevents the first driving sleeve from synchronously rotating, and the first driving sleeve can only axially move to the rear end of the axial sliding groove and abut against the first guide sliding block. That is to say, the upper end of the first guide sliding block is located at the starting end of the circumferential sliding groove of the first driving sleeve, and in the process, the steel wire pull wire wound on the driving end of the first driving sleeve cannot drive the lock tongue to move; when the unlocking key of the remote control key is pressed again, the driving motor continues to rotate in the forward direction, and the upper end of the first guide sliding block is located at the starting end of the circumferential sliding groove of the first driving sleeve, so that the first driving sleeve is prevented by the first guide sliding block and cannot move axially, the first driving sleeve synchronously rotates along with the lead screw, the driving end of the first driving sleeve winds a steel wire pull wire for controlling the lock tongue, the lock tongue rotates to a release position from a locking position, and the upper end of the first guide sliding block moves to the tail end from the starting end of the circumferential sliding groove of the first driving sleeve. Meanwhile, the second guide sliding block is positioned at the starting end in the circumferential sliding groove of the second driving sleeve, so that the second driving sleeve cannot rotate continuously due to the stop of the second guide sliding block, the second driving sleeve moves axially until the second guide sliding block is positioned at the front end of the axial sliding groove of the second driving sleeve, and at the moment, the steel wire pull wire wound on the driving end of the second driving sleeve cannot drive the safety baffle to move.
When a locking key of the remote control key is pressed, the driving motor rotates reversely, and because the upper end of the first guide sliding block is located at the tail end of the circumferential sliding groove of the first driving sleeve, the first guide sliding block prevents the first driving sleeve from moving axially and slides from the tail end to the starting end in the circumferential sliding groove, the first driving sleeve synchronously rotates reversely along with the lead screw until the first guide sliding block rotates to the starting end of the circumferential sliding groove, the first guide sliding block at the moment is aligned with the axial sliding groove of the first driving sleeve, the driving end of the first driving sleeve releases a steel wire pull wire for controlling the lock tongue, and the first return spring enables the lock tongue to automatically return to the locking position from the releasing position. Along with the continuous reverse rotation of the driving motor, the first guide sliding block positioned at the rear end of the axial sliding groove of the first driving sleeve prevents the first driving sleeve from continuously rotating and changing into axial movement until the first guide sliding block moves to the front end of the axial sliding groove of the first driving sleeve; meanwhile, the second guide sliding block positioned at the front end of the axial sliding groove of the second driving sleeve prevents the second driving sleeve from rotating, and the second driving sleeve moves axially instead until the second guide sliding block moves to the rear end of the axial sliding groove of the second driving sleeve. The second driving sleeve can not move axially and can rotate reversely along with the continuous reverse rotation of the driving motor, the second guide sliding block is arranged at the tail end in a sliding way in the circumferential direction of the second driving sleeve from the starting end, the driving end of the second driving sleeve releases a steel wire pull wire for controlling the safety baffle, and the second return spring enables the safety baffle to rotate from an unlocking state to a locking state.
