Abstract
The utility model relates to an automobile anti-collision mechanical lock, which belongs to the automobile manufacturing industry. Under conditions of automobile collision, door locks is not locked up. The utility model adopts the following technical scheme to solve the technical problems: a lockup switch converting plate is mounted on the automobile anti-collision mechanical lock; the automobile anti-collision mechanical lock is characterized in that: the lockup switch converting plate is a shape body with a light upper part and a heavy lower part, wherein the lower end of the shape body has a fan shaped structure, and the mass center is under a rotary shaft hole; and the principle of the automobile anti-collision mechanical lock is that the device overcomes a structural defect that a mass center of a linkage rod of an original automobile lock is above a rotation point, and designs the lockup switch converting plate that the mass center is under the rotary shaft hole and the lower end has a fan-shaped structure. When a high velocity collision of an automobile occurs, a torque is generated to prevent a door lock mechanism from locking up by the lockup switch converting plate under the action of inertia, thereby the door locks or the automobile is not locked up, and the doors of the automobile can be opened normally. The automobile anti-collision mechanical lock of the utility model has the advantages of simple structure and low cost, and is suitable for locks used in economical minivans.
Description
Affiliated technical field
The utility model relates to a kind of automobile collision preventing mechanical lock, belongs to auto manufacturing.
Background technology
The economical minibus of present China, the slippage door is generally adopted at the back door, and mostly door lock is the manipulator moving lock, and its shortcoming is that automobile receives when more seriously colliding, and car door can't normally be opened because of latching.Because car door distortion does not cause, but inertia force is excessive to be caused the reason that latches owing to door lock receives.In order in time to rescue the occupant, the methods of destroying car door that adopt are rescued the people more, so not only result in greater loss, and delay rescue time.
Summary of the invention
The purpose of the utility model is to design a kind of automobile collision preventing mechanical lock, and through experiment showed, this automobile collision preventing mechanical lock, when car crass is very serious (stressed two times of the GB settings that surpass), car door lock still can normally be opened, and reaches the purpose that does not latch.The utility model solves the technical scheme that its technical problem adopted: a locking switch transition plate is installed on a kind of automobile collision preventing mechanical lock; It is characterized in that: a rotation axis hole is arranged on the locking switch transition plate; There is a connecting hole on the top on the rotation axis hole, in rotation axis hole lower end a segment is arranged.Its principle is: this device has overcome the fault of construction of former lock trace barycenter on the point of rotation, and be designed to barycenter the rotation axis hole below and the lower end be the locking switch transition plate of sector structure.Automobile produces the moment that door lock mechanism is latched when high velocity impact, be directly proportional with acceleration, and when this moment during greater than torsion spring moment, door lock mechanism will latch, and door is not just opened.The utility model automobile collision preventing mechanical lock is the structure of centroid position under the rotation axis hole owing to adopt the shape of locking switch transition plate.Under the car crass condition, produce the moment that stops door lock mechanism to latch, guarantee automobile after collision, door lock can normally be opened.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Accompanying drawing is an automobile collision preventing mechanical lock assembling drawing.Among the figure, 1 is locking switch transition plate; 2 is locking switch connecting rod; 3 is attacker's change-over panel; 4 is attacker's connecting rod; 5 is the door lock change-over panel; 6 is door lock link; 7 is torsion spring; 8 is transaxle; 9 is the unlocked position of A-A locking switch transition plate; 10 is the lock position of B-B locking switch transition plate; 11 are the rotation axis hole; 12 is connecting axle; 13 is segment.
The practical implementation method
The utility model automobile collision preventing mechanical lock course of action is following: automobile is pressed the locking button when cruising, prevents that maloperation from opening car door and the accident that meets accident, and the inside and outside personnel of car this moment can not open car door.After stopping, open the locking button after, the inside and outside personnel of car could open car door.Former car door lock is when collision is serious, and car door lock just produces the phenomenon that latches under effect of inertia, and the outside personnel can't open car door and implement rescue.The utility model automobile collision preventing mechanical lock stops the moment that latches because locking switch transition plate (1) produces under effect of inertia, just make locking switch transition plate (1) can not forward the lock position of B-B locking switch transition plate to.So after collision takes place; As long as the outside personnel draw back car door buckle,, drive attacker's change-over panel (3) and rotate through the effect of attacker's connecting rod (4); Attacker's change-over panel (3) drives door lock change-over panel (5) co-rotation through transaxle (8), and door lock change-over panel (5) is opened car door through door lock link (6).The rescue personnel in time rescues.The utility model automobile collision preventing mechanical lock, simple in structure, cost is suitable for economic shape bread Vehicle lock the end of than.
Claims (2)
1. automobile collision preventing mechanical lock; Lock at crashproof machinery a locking switch transition plate is installed; It is characterized in that: a rotation axis hole (11) is arranged on the locking switch transition plate (1); Going up the top at rotation axis hole (11) has a connecting hole (12), in rotation axis hole (11) lower end a segment (13) is arranged.
2. automobile collision preventing mechanical lock according to claim 1 is characterized in that: locking switch transition plate (1) is that lightness sensation in the upper and heaviness in the lower, lower end are fan-shaped and the part of barycenter under rotation axis hole (11).
