Description

Automobile door locking device
Technical Field
The invention relates to the field of automobile accessories, in particular to an automobile door locking device.
Background
Modern automobiles, particularly commercial automobiles, are often equipped with sliding doors at the rear that seal and open the space by rearward movement of the door (rather than side-by-side or side-by-side). The user realizes the opening and closing of the sliding door through the handle of the sliding door.
The structure of the existing mature sliding door inner opening device (hereinafter referred to as an inner opening device) is shown in fig. 1, and the structure is generally composed of an inner opening device lock body connecting rotating arm 111, an inner lock safety connecting rotating arm 112, an inner lock safety connecting pull rod 113, an outer opening connecting rotating arm 114 and an outer opening handle connecting pull rod 115, so that functions of inner safety, inner safety releasing, inner unlocking, outer unlocking and the like of a sliding door lock can be realized.
However, the installation position of the conventional sliding door inward opening device is generally shown in fig. 2, and the dotted line part in fig. 2 is the arrangement position of the waterproof film 1, and it can be seen that the inward opening device 110 is wrapped inside the waterproof film 120. However, since the waterproof film needs to be perforated to penetrate the handle (hereinafter referred to as an inward opening handle) for opening the sliding door of the automobile from the interior of the compartment, rainwater, dust and the like can enter the passenger compartment of the whole automobile through the gap at the inward opening device and the gap of the inner plate, so that the tightness level of the whole automobile is reduced, and the problems of wind noise and the like are caused. And the entering sand dust, rainwater and the like can cause the problems of rust, clamping stagnation and the like of the transmission mechanism of the inward opening device, so that the inward opening device is invalid and the like.
In addition, the existing automobile sliding door locking device cannot realize automatic locking after the sliding door is opened to the maximum position so as to prevent the sliding door from being automatically closed under the condition of gradient.
Disclosure of Invention
The invention aims to provide an automobile door locking device, which aims to solve the problem that the sealing effect of the existing automobile sliding door is poor.
The invention is realized in the following way: an automobile door locking device comprises a rear side door inner plate arranged inside an automobile sliding door; the avoidance hole is arranged on the inner plate of the rear side door and is provided with a groove structure; the inner opening device is the same as the avoidance hole in shape and is embedded into the avoidance hole; a waterproof film connected to and covering the rear side door inner panel to protect the rear side door inner panel from external water dust; and the inward opening sealing device is connected with the inward opening device and covers the inward opening device to protect the inward opening device from external water dust. The sealing of the inward opening device is isolated from the sealing of the inner plate of the automobile, so that the defect that the original waterproof film needs to be provided with holes to break the sealing property is avoided. The sealing structure can be integrated on the original inward opening device assembly, so that an assembly process is not required to be increased in a workshop. The sealing structure can play a good waterproof and dustproof effect when the inner opening device assembly is assembled on the side door inner plate, and water can not contact with the interior decoration sealing plate through a gap between the inner opening device and the side door inner plate via hole when water leakage occurs, so that the sealing plate is mildewed.
The invention further adopts the technical scheme that: the inward opening device is provided with a guide rail lock unit which is automatically locked after the automobile sliding door is opened to the maximum position. The existing sliding door cannot be fixed after being opened. When the road surface is smoother, the sliding door cannot be automatically closed due to certain friction force, but when the sliding door is positioned on a downhill road surface, the sliding door automatically moves to the closing direction under the action of gravity after being opened, so that a plurality of inconveniences are brought.
The invention further adopts the technical scheme that: the guide rail lock unit comprises a guide rail lock opening rotating arm which is arranged on the inward opening device and used for controlling the guide rail lock unit to unlock through rotation; a rail lock opening cable connected to the rail lock opening rotary arm and transmitting rotation of the rail lock opening rotary arm by contraction; the guide rail lock body is connected with the guide rail lock opening inhaul cable and converts the contraction of the guide rail lock opening inhaul cable into rotation; and the guide rail lock catch is arranged on the C column of the automobile and meshed with the guide rail lock body to lock the sliding door of the automobile.

At this time, the child LOCK driving lever 81 is in LOCK state, the child LOCK driving lever 81 drives the middle shaft 73 to the right through the child LOCK connecting rod 82, at this time, the inner opening handle 7 is pulled to drive the first rotating arm 72, and the first rotating arm 72 cannot contact with the middle shaft 73 when being pressed down, so that the second rotating arm 74 cannot be driven to unlock each LOCK, and the purposes that the inner opening handle 71 fails and unlocking cannot be unlocked under the condition of unconsciousness of children are achieved.
Fig. 21 is a schematic structural view of an automobile sliding door child protection unit of an automobile door locking device provided by an embodiment of the invention in an unlocked state. When the child lock deflector 81 is in the UNLOCK state, the inner opening handle 71 directly acts on the first rotating arm 72 after being unlocked, the first rotating arm 72 is pressed downwards through the intermediate shaft 73, when the intermediate shaft 73 is pressed downwards, the second rotating arm 74 is driven to rotate leftwards, and the second rotating arm 74 pulls the front lock opening rotating arm 61, so that the front lock unit 6 is unlocked, and the vehicle door can be opened.
The automobile door locking device solves the problem of water leakage and ash leakage of the whole automobile; the tightness level of the whole vehicle is improved, the wind noise of the whole vehicle is reduced, and the problems of rust, clamping stagnation and even failure of the inward opening device caused by sand dust, rainwater and the like entering the rotation mechanism of the inward opening device are avoided; in addition, the inward opening device is also provided with a front lock unit and a guide rail lock unit, so that the sliding door can not be opened without a handle after being closed, and can be fixed after being opened to the maximum position; control units for the respective lock bodies, and an internal unlocking handle and a child protection device which are matched with the control units are also designed to ensure the safety and the effectiveness of use.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
