In addition, after the accident is over, the door lock should not fail and the door should still be able to open.

The door lock system is an indispensable part of a whole automobile system of an automobile, has irreplaceable effects on normal closing, theft prevention and side collision safety lifting of an automobile door, is continuously updated and replaced at the present of rapid development of technology, has more and more functions, and is designed and developed from the aspects of use experience, safety and the like no matter how the functions are increased.

Because the service environment of truck is more abominable, so this kind of lock body 4's external-open mechanism, external locking mechanism are the full enclosed construction, can prevent effectively that rainwater and dust from getting into inside the lock body, extension lock body life. Meanwhile, the structure of the door lock plays a very great role in improving the quality of the sound of opening and closing the high-quality door. The selection and arrangement of the door lock are studied here, and the arrangement of the door lock and the inner and outer handles includes the arrangement of the lock body 4, the shackle 5, the inner opening handle 10 and the outer opening handle 20.

For the arrangement of the lock body 4:

the arrangement of the lock body 4 is generally divided into X, Y and Z directions, wherein the position of the lock body 4 in the X direction is generally ensured to be more than 6mm away from the lifter guide rail 2 behind the glass in order to avoid interference with the lifter guide rail 2 of the glass; the position of the lock body 4 in the Y direction is generally ensured to have a minimum clearance of more than 10mm in order to avoid interference with the inner surface of the glass; the position of the lock body 4 in the Z direction is generally located between the upper hinge and the lower hinge, but the specific position needs to be determined according to the center of gravity, the structure and the modeling surface of the vehicle door.

On this basis, in the arrangement of lock body 4, a knob is added at the fish mouth to lock 4 urgent lock of lock body, inserts the rotation through the key and realizes urgent locking function, has the advantage that need not the extra trompil of panel beating.

In addition, in order to ensure that the door can be stably matched with the door lock catch in a closed state, the lock catch is arranged in a way that the axis of the lock catch is vertical, the inner surface of the lock tongue is parallel to the installation surface of the lock catch, and the gap between the inner surface of the lock tongue and the lock catch is not less than 3.5 mm.

In this embodiment, the internally opening handle 10 is connected to the lock body 4 by an internal locking cable 30.

Further, the closed area of the inner locking stay wire 30 is molded integrally with the stay wire, i.e., the closed area of the inner locking stay wire is molded integrally with the stay wire by the arrangement of the door lock rod and the stay wire.

Further, 4 internal integrations of lock body have a door lamp signal, and door lamp signal integration is inside the lock body promptly, and the door frame need not adorn the base knob switch, and stability is higher.

Besides, the gap between the control rod piece and the static piece of the gap of the door lock rod piece is controlled to be at least more than 8mm, the distance between the rod piece and the moving piece is controlled to be at least more than 16mm, the problem is further noticed in the arrangement of the outward opening pull rod and the lock cylinder pull rod, and the phenomenon that the mistaken door opening action is caused by interference is prevented.

For the arrangement of the lock body 4 and the shackle 5:

the shackle 4 is mounted on the side wall outer plate of the car body, in order to ensure smooth engagement between the lock body 4 and the shackle 5, the engagement center line of the shackle 5 and the lock body 4 in the Y direction is perpendicular to the hinge axis, as shown in fig. 4, and the clearance L between the lock body 4 and the inner surface of the lock tongue 1 in the shackle 5 is required to be not less than 3.5mm, as shown in fig. 5, which varies depending on the lock body in different forms.

Furthermore, the position of the lock body 4 in the X direction is higher than the lifter guide rail 26mm of the glass, the position in the Y direction is spaced from the inner surface of the glass by more than 10mm, and the position in the Z direction is positioned between the upper hinge and the lower hinge and higher than the gravity center of the vehicle door or is arranged on the same horizontal line with the gravity center of the vehicle door, so that the gravity center of the vehicle door is positioned in a triangular area formed by the lock body 4 and the upper hinge and the lower hinge.

In addition, the relationship between the door lock body 4 and the shackle 5 in the Y direction: the door lock is arranged in a closed state of the vehicle door, and the surface of the door lock clamping plate close to the inner side of the vehicle body is ensured to be in contact with the lock catch when the door lock is arranged due to the outward reaction action of the sealing strip under the closed state of the vehicle door; relationship of door lock body 4 and lifter guide rail 2: the door lock body 4 is mostly arranged on the inner side of the lifter guide rail 2 (the clearance between the door lock body and the rear guide rail is more than 10mm), so that the arrangement of each linkage rod of the lock body 4 is facilitated; arrangement positions of the lock body 4 and the shackle 5 in the Z direction: the lock body 4 is slightly higher than the gravity center of the vehicle door or is arranged on the same horizontal line with the gravity center of the vehicle door, so that the gravity center of the vehicle door is ensured to be positioned in a triangular area formed by the door lock and the upper and lower hinges, and the arrangement can ensure that the vehicle door is more stable after being closed from the stress angle, and can avoid the highest point of the vehicle door from vibrating during driving.

For the arrangement of the internally open handle 10:

the inward opening can be developed into single-pull and double-pull unlocking, an inner locking pull wire 30 can be omitted, the operation convenience of a user can be improved while the cost is reduced, the position of the inward opening handle 10 is close to the A column and is arranged on the inner plate 3 of the vehicle door, the initial arrangement of the inward opening handle 10 is determined in the modeling stage, the position of the inward opening handle meets the requirements of human engineering, the operation is convenient, and the inner surface cannot be protruded so as to prevent the false opening. After the door panel design is completed, the inward opening handle 10 needs to be arranged in detail, the arrangement of the inward opening handle in the X direction and the Z direction is determined according to factors such as sheet metal parts, interior trim panels, electric parts, self structures and the like, the interference between the inner handle and peripheral parts is required, and smooth connection between the inner handle and the lock body is ensured.

For the arrangement of the out-opening handle 20:

the pull wire of the outward opening handle 20 is sealed by a cover plate, that is, the outward opening pull wire arranged on the outward opening handle 20 is sealed by a cover plate. The position of the outward opening handle 20 is close to the position of the lock body 4 in the X direction as much as possible, so that the movement amount of the deformed connecting rod can be reduced, and the door opening force is prevented from being increased due to the bending of the connecting rod.

The position of the outward opening handle 20 in the Z direction is as ergonomic as possible, and its height from the ground (D) is generally L1: 1600 ~ 1750mm, as far as possible and the focus of door are in a high position, can reduce the door and open the power of getting. The matching of the outward opening handle 20 and the door lock mainly comprises the matching of the stroke of the outward opening handle 20 and the force of the outward opening handle, and the magnitudes of the stroke of the outward opening handle 20 and the force of the outward opening handle 20 are mainly determined according to man-machine. When the strokes of the external-open handle are matched, the rule to be met firstly is as follows: the unlocking stroke is less than the full stroke of the outward opening handle 20 and less than the full stroke of the door lock, then the pulling-out stroke of the outward opening handle 20 is determined according to the man-machine relationship, the pulling-out stroke is used as an input condition, and the rotating angle of a driving lever of the outward opening handle 20 is obtained, and the rotating angle is the full stroke of the outward opening handle 20. When the full stroke of the out-opening handle 20 is known, the magnitude of the unlocking stroke of the out-opening handle 20 and the full stroke of the door lock can be obtained by considering the idle stroke (mainly from the viewpoint of man-machine) after the out-opening handle 20 is unlocked and the manufacturing error. The full stroke of the external-open handle is generally selected to be 22-25 mm.

In addition, in the force matching of the outside handle 20, during the unlocking of the outside handle 20, the unlocking force F includes the torsion force F1 of the return spring of the outside handle 20 and the torsion force F2 of the door lock return spring, and F1+ (l2/l) F2. F1 and F2 increase progressively with outward opening of the outward opening handle 20, and l2 is the equivalent moment arm of the outward opening handle 20 and the equivalent moment arm of the lock body. In the design, the magnitude of the unlocking force F of the external-opening handle is determined according to the man-machine relationship. According to the data measured by the reference vehicle, the unlocking initial load and the full stroke load of the out-opening handle 20 should be satisfied in the range of 30N to 45N. After F is determined, F is in the most comfortable range of man-machine by reasonably distributing the sizes of F1 and F2 and adjusting the relationship of the two force arms in the whole stroke.

For better technical effect, the door lock system has the following influence on the opening and closing tone quality of the vehicle door:

the door lock should have a two-stage locking function. The lock system will sound when the door continues to close, bringing the pawl on the lock body 4 into contact with the lock pin. The initial impact force of the door on the lock pin depends on the static spring load stiffness of the door lock and the dynamic door lock stiffness generated by inertia. The initial impact force is reduced, and the loudness and sharpness of the whole closing sound can be effectively reduced. The dynamic force of the door lock is self-locking to a high moment of inertia near the axis due to excess material and large turning radius of mass relative to the axis. High dynamic forces indicate that strong thrust forces are transmitted to the latch pin and the door, causing high frequency noise. After the door lock is locked at a first level, the pawl can enter the main pawl brake, and then the auxiliary pawl brake is locked to realize secondary locking. This phenomenon occurs approximately 10ms apart for a closure process of 1 m/s. Since the impact is a metal-to-metal impact, each interaction results in a small high frequency energy pulse. The impact force transmitted to the lock mechanism by the impact will cause the internal mechanism of the door lock to vibrate and rattle. The 50% sharpness of the door sound originates from the door lock and catch 5.

The invention also provides a vehicle comprising the door lock system, which has all the beneficial effects of the door lock system: the automobile door lock system plays an important role in normal closing and theft prevention of the automobile door, improvement of side collision safety and the like. Meanwhile, the structure of the door lock plays a very great role in improving the quality of high-quality opening and closing sound of the vehicle door; this paper focus has studied the lectotype and the arranging of lock, because the service environment of truck is more abominable, so this kind of lock body 4's external-open mechanism, external locking mechanism are for enclosing the structure entirely, can prevent effectively that rainwater and dust from getting into inside the lock body, extension lock body life. With the progress of the automobile industry, the requirements on the opening and closing system are higher and higher, and the opening and closing system is developed from a simple mechanical motion to an electric motion and further to intellectualization. The door lamp signal integration is inside the lock body, and the door frame need not adorn the base knob switch, and stability is higher.
