Technical Field
The invention relates to the field of electric locks, in particular to an electric self-suction lock.
Background
At present, a bus door and a passenger door are not locked by a lock, the bus door is completely pulled by a cylinder, and the bus door can be automatically opened if the cylinder is cut off or the air leakage occurs, so that the bus is very unsafe. The existing passenger car is mainly lifted and self-locked by a car door, and if a lifting mechanism is damaged, the car door can be automatically opened, so that the passenger car is unsafe. In both of these doors, when the door driving mechanism is damaged, the door cannot be manually closed, and in order to improve the safety and convenience of the door, researchers in the field mainly put the object of study on the structure of the door lock.
Disclosure of Invention
The purpose of the invention is as follows: aiming at the problems in the prior art, the invention provides the electric self-absorption lock which can be manually unlocked no matter which state a locking motor is damaged when a door lock is in, and has the advantages of reasonable structural design, safety and reliability.
The technical scheme is as follows: the invention provides an electric self-priming lock which comprises a base, a locking motor, a gear piece, a stop block, a poking rod, a first web lock block, a limiting block, an unlocking piece and an unlocking motor, wherein the locking motor is fixed on the base, an output shaft of the locking motor is meshed with one side of the gear piece, the other side of the gear piece is rotatably connected with the base, one end of the poking rod is rotatably and rotatably connected with the other side of the gear piece, and the other end of the poking rod is always tangent to one end of the stop block before the electric self-priming lock is unlocked; the abutting block, the poking rod, the jaw locking block, the limiting block and the unlocking plate are rotatably and rotatably connected with the base, and the gear piece, the poking rod, the jaw locking block and the limiting block are sequentially and rotatably linked; the output shaft of unblock motor pass through the wire drawing with the one end of separating the locking plate is connected, separate the locking plate with the stopper and be the swivelling joint between the drive block and move, separate the locking plate with the stopper and support and be the swivelling joint between the dog.
Further, the poke rod and one end of the abutting block, which is tangent to the abutting block, are provided with rollers. The installation of the roller enables sliding friction between the abutting block and the poking rod to be changed into rolling friction, so that friction force between the abutting block and the poking rod is greatly reduced, the abutting block can be easily separated from the poking rod during unlocking, and the driving power of the unlocking motor is reduced.
Further, before the electric self-suction lock is unlocked, the roller and the gear piece rotate coaxially all the time. Before the electric self-suction lock is unlocked, the roller always rotates coaxially along with the gear piece.
Furthermore, a linkage block is fixed on a rotating shaft D of the limiting block, and the unlocking plate is rotationally linked with the limiting block through the linkage block.
Furthermore, the electric self-priming lock also comprises a controller in signal connection with both the locking motor and the unlocking motor, and a rotary switch and a contact switch in signal connection with the controller; the rotary switch is fixed on a rotating shaft C of the first web lock block, a contact piece is rotatably connected on the rotating shaft C, and the first web lock block is connected with the contact piece through a contact column fixed on the first web lock block; when the first-pass lock is unlocked, the contact piece is contacted with a first contact of the rotary switch, when the first-pass lock is locked, the contact piece is contacted with a second contact of the rotary switch, and when the second-pass lock is locked, the contact piece is contacted with a third contact of the rotary switch; the contact switch is separated from the linkage block when unlocked. The arrangement of the controller, the contact switch and the rotary switch enables the electric self-priming lock to be automatically unlocked and locked.
Preferably, the abutting block is rotatably and rotatably connected with the base through a first rotating member, one end of the first rotating member is fixedly connected with the abutting block, and the other end of the first rotating member is fixedly connected with the base. The first rotating part preferably uses a torsion spring, one end of the torsion spring is fixedly connected with the abutting block, the other end of the torsion spring is fixedly connected with the base, and the middle part of the torsion spring is wound on a rotating shaft A of the abutting block.
Preferably, the unlocking sheet and the abutting block are coaxially fixed. The unlocking sheet and the abutting block are coaxially fixed, so that the electric self-priming lock is simple and reasonable in internal structure.
Preferably, one end of the poke rod is rotatably connected with the other side of the gear piece through a second rotating piece, one end of the second rotating piece is fixedly connected with the poke rod, and the other end of the second rotating piece is fixedly connected with the gear piece. The second rotating part preferably uses a torsion spring, one end of the torsion spring is fixedly connected with the poke rod, the other end of the torsion spring is fixedly connected with the gear piece, and the middle part of the torsion spring is wound on a rotating shaft B of the poke rod.
Preferably, the first web lock block is rotatably connected with the base through a third rotating member, one end of the third rotating member is fixedly connected with the first web lock block, and the other end of the third rotating member is fixedly connected with the base. The third rotating part preferably uses a torsion spring, one end of the torsion spring is fixedly connected with the first web locking block, the other end of the torsion spring is fixedly connected with the base, and the middle part of the torsion spring is wound on a rotating shaft C of the first web locking block.
Preferably, the limiting block is rotatably connected with the base through a fourth rotating part, one end of the fourth rotating part is fixedly connected with the limiting block, and the other end of the fourth rotating part is fixedly connected with the base. The fourth rotating part preferably uses a torsional spring, one end of the torsional spring is fixedly connected with the limiting block, the other end of the torsional spring is fixedly connected with the base, and the middle part of the torsional spring is wound on a rotating shaft D of the limiting block.
Has the advantages that: compared with the prior art, the electric self-suction lock has the following advantages:
when the unlocking plate is driven to rotate by the unlocking motor, the unlocking plate can be separated from the shifting rod by the driving abutting block, so that the shifting rod is reset, and meanwhile, the driving limiting block is separated from the tiger mouth locking block, so that the situation that when the motor is locked, the locking plate can be unlocked by manually pulling a drawn wire can be ensured, because the shifting rod is a component for driving the lock catch to be locked, and the shifting rod cannot be manually reset in the prior art, when the motor is locked, the lock catch cannot be manually unlocked because the shifting rod cannot be reset; and among the electronic self-priming lock in this application, can separate it and poker rod through manual pulling wire drawing drive block to make the poker rod can manual reset, promptly, no matter what kind of state this electronic self-priming lock is in, all can be through manual pulling wire drawing unblock, avoid the vehicle to lock the motor and can't use when breaking down or traffic accident and lead to the state that the door lock can not be opened, effectively promote this electronic self-priming lock's security performance.
