Description

Technical Field

[0001] The utility model relates to the technical field of automobile design and manufacture, and more specifically, to a door lock system structure for realizing an emergency lock function of automobile doors. Background Art

[0002] At present, most car door locks are only equipped with a mechanical key system on the left front door (some new energy models even completely eliminate mechanical keys). Figure 1 As shown, the door lock system consists of a tailgate lock body 1, a mechanical external opening buckle 2 and an external opening pull wire 3. The rear door mostly adopts a knob or a lifting button mechanical locking mechanism. Due to differences in function definitions (such as doors equipped with internal double-pull opening function door locks), some cars have cancelled the locking mechanical mechanism inside the car. Because special situations such as accidental power failure or key failure in the car are not considered, some doors are not equipped with an emergency locking function, resulting in the failure of the door lock to lock when the electric lock fails, affecting the safety of the car and the items inside the car. There are also some cars, such as Volkswagen series models, equipped with door locks integrated with emergency lock functions. When the vehicle electric lock fails, the door lock can be locked by turning the knob switch on the door lock with a mechanical key tooth or a similar tool, and then closing the door. This door lock with integrated emergency lock function has a complex structure and high cost, and a hole for the knob switch needs to be reserved on the inner panel of the door.

[0030] The structure of the door lock system for realizing the emergency lock function of the automobile door of the utility model will be further described below in combination with specific embodiments, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the technical solution of the utility model.

[0031] Example 1

[0032] like Figure 2-8As shown, the door lock system structure for realizing the emergency locking function of the automobile door of this embodiment includes a tailgate lock body 1, a mechanical outer opening button 2, an outer opening cable 3, a tailgate locking cable 4, a logic conversion box 5, a locking operating cable 6 and a locking operating mechanism 7. The mechanical outer opening button 2 is connected to the tailgate lock body 1 through the outer opening cable 3, and the logic conversion box 5 is connected to the tailgate lock body 1 through the tailgate locking cable 4. The locking operating mechanism 7 is connected to the logic conversion box 5 through the locking operating cable 6. When the tailgate lock body 1 is in the unlocking state, the mechanical outer opening button 2 can be pulled to realize the unlocking of the tailgate lock through the mechanical transmission of the outer opening cable 3. The tailgate lock cable 4 is used to lead out the locking function of the tailgate lock body 1, connected to the logic conversion box 5, and then the logic conversion box 5 and the locking operating mechanism 7 are connected through the locking operating cable 6; because the door lock mechanism to achieve locking requires a pushing action, the logic conversion box 5 can convert the pushing action to the locking operating mechanism 7 into a pulling action; the function of the logic conversion box 5 can be realized: when the locking operating mechanism 7 is pulled, the tailgate lock body 1 can be placed in a locked state, and when the locking operating mechanism 7 is pushed, it does not affect the locking state of the tailgate lock body 1, so the locking operating mechanism 7 can be installed inside the vehicle or outside the vehicle. The tailgate lock body 1 can be electrically unlocked by placing the locking operating mechanism 7 in the initial state through the logic conversion box 5. The electric locking and unlocking of the tailgate lock body 1 will not affect the state of the locking operating mechanism 7.

[0033] like Figure 3-5 As shown, the logic conversion box 5 includes a logic conversion box body 501, in which a tailgate locking wire slider 503 and a locking operating wire slider 504 are arranged, a side wall of the logic conversion box body 501 is provided with a mounting buckle 502, and a logic conversion box cover 505 is arranged on the logic conversion box body 501. The logic conversion box body 501 is provided with a clamping structure for the tailgate locking wire 4 and the locking operating wire 6.

[0034] The sleeve of the tailgate locking wire 4 is clamped on the logic conversion box body 501. The tailgate locking wire 4 is connected to the tailgate locking wire slider 503 through a wire drawing casting head. The tailgate locking wire 4 is a single steel wire with a larger diameter, which can transmit both tension and thrust. A convex rib is provided at the bottom of the tailgate locking wire slider 503, and a slide groove and a guide clamping structure that is deformed by force are provided at the bottom of the logic conversion box body 501. When the tailgate locking wire slider 503 is installed in the slide groove of the logic conversion box body 501, the guide clamping structure returns to its original position, so that the tailgate locking wire slider 503 can slide back and forth without falling out.

[0035] The sleeve of the locking operating wire 6 is clamped on the logic conversion box body 501. The locking operating wire 6 is connected to the locking operating wire slider 504 through a wire drawing casting head. The inner wire drawing of the locking operating wire 6 is a multi-strand steel wire with a smaller diameter, which can only transmit tension. The bottom of the locking operating wire slider 504 is provided with a convex rib, and the bottom of the logic conversion box body 501 is provided with a slide groove and a guide clamping structure that is deformed by force. When the locking operating wire slider 504 is installed in the slide groove of the logic conversion box body 501, the guide clamping structure returns to its position, so that the locking operating wire slider 504 can slide back and forth without falling out.

[0036] The logic conversion box cover 505 is clamped on the shaft and the clamping protrusion of the logic conversion box body 501, and can be rotated around the shaft to open and close. The logic conversion box cover 505 can prevent the tailgate locking cable 4 and the locking operation cable 6 from coming out, and can keep the logic conversion box 5 clean, thereby ensuring the reliability of the machine.

[0037] like Figure 6-8 The other end sleeve of the locking operating wire 6 is clamped on the locking operating mechanism body 701, and the wire drawing casting head of the locking operating wire 6 is connected to the locking operating mechanism slider 703; the bottom of the locking operating mechanism slider 703 is provided with a convex rib, and the bottom of the locking operating mechanism body 701 is provided with a bottom slide groove and a bottom opening. The locking operating mechanism slider 703 can be moved back and forth by using a mechanical key tooth piece or a similar tool through the bottom opening of the locking operating mechanism body 701. The locking operating mechanism box cover 702 is clamped on the clamping convex point of the locking operating mechanism body 701, which can prevent the locking operating wire 6 from falling out and keep the inside of the locking operating mechanism 7 clean, thereby ensuring the reliability of the machine.

[0038] Reference Figure 9-12In actual use, the locking operating mechanism slider 703 is moved through the bottom opening of the locking operating mechanism body 701 by a mechanical key tooth or similar tool, and the locking operating wire slider 504 is driven to slide by the locking operating wire 6. The locking operating wire slider 504 will drive the tailgate locking wire slider 503 to slide, and the tailgate lock is locked by actuating the internal mechanical locking mechanism of the tailgate lock body 1 by the tailgate locking wire 4 using a single steel wire with a larger diameter, thereby locking the tailgate and the vehicle. After the tailgate is locked, if the locking operating mechanism slider 703 is moved back through the bottom opening of the locking operating mechanism body 701 by a mechanical key tooth or similar tool, the locking operating wire 6 drives the locking operating wire slider 504 to slide, but the locking operating wire slider 504 will not drive the tailgate locking wire slider 503 to slide, so the tailgate lock body 1 will not be unlocked, thereby achieving anti-theft. When the tailgate lock body 1 is locked by electric control, the mechanical locking mechanism inside the tailgate lock body 1 drives the tailgate lock wire slider 503 to slide through the tailgate lock wire 4 of a single steel wire with a larger diameter. The sliding of the tailgate lock wire slider 503 drives the lock operating wire slider 504 to slide, and the lock operating mechanism slider 703 is restored to the initial position through the lock operating wire 6. When the tailgate lock body 1 is locked by electric control, the mechanical locking mechanism inside the tailgate lock body 1 drives the tailgate lock wire slider 503 to slide, but the sliding of the tailgate lock wire slider 503 does not drive the lock operating wire slider 504 to slide. It will not affect the state of the lock operating mechanism 7.

[0039] This patented door lock system solution can be applied to the front and rear doors of all models, SUV tailgates, and car trunk lids, and is suitable for all car door locks with mechanical locking structures. When the vehicle loses power or the key fails, the emergency locking of the door can be achieved inside or outside the vehicle; the mechanical device has stable performance, low cost, reliable operation, and easy use; the locking operating mechanism 7 can be installed on the interior decoration or exterior decoration, or it can be integrated with the external opening operating mechanism such as the door handle. The following is a specific example of applying this patent to the SUV tailgate, where the locking operating mechanism 7 is installed on the rear tailgate exterior decoration, and the logic conversion box 5 is installed on the rear tailgate sheet metal inner panel.

[0040] For ordinary technicians in this field, the specific embodiments are only illustrative descriptions of the utility model. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, they are all within the protection scope of the utility model.
