DESCRIPTION OF EMBODIMENTS

(6) The following will provide a clear and complete description of the technical solution in the embodiments of the present disclosure, based on the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present disclosure.

(7) Please refer to FIGS. 1-4. The present disclosure provides a technical solution: an adjustable door latch includes a base part 3, and the base part 3 is flat and fixedly connected to an inner wall of the vehicle door. One side of the base part 3 is integrally provided with a clamping part 1. A ventilation groove 7 is provided at a middle of the base part 3, and a positioning hole 8 is provided on the ventilation groove 7. A rebound pin 4 is provided on the base part 3, and a movable lock tongue 5 is provided in the ventilation groove 7. The movable lock tongue 5 is provided with spaced adjustment holes 6, the adjustment holes 6 cooperate with the positioning holes 8 to achieve a telescopic positioning of the movable lock tongue 5 through the rebound pin 4. A bottom end of the rebound pin 4 is penetrated the positioning hole 8 and is inserted into the adjustment hole 6.

(8) During a specific implementation, the flat base part 3 is placed in close contact with an inner wall of the vehicle door, and the clamping part 1 is facing towards a direction of the vehicle door lock, the vehicle door is closed, and the clamping part 1 interacts with the vehicle door lock to achieve preliminary fixation. When adjusting the ventilation volume, the movable lock tongue 5 is manually pulled to slide inside the ventilation groove 7, and the adjustment holes 6 spaced apart on the movable lock tongue 5 will move accordingly. According to a required size of the ventilation opening, the movable lock tongue 5 is held in an appropriate position. At this time, the positioning hole 8 on the ventilation groove 7 of the base part 3 is aligned with one of the adjustment holes 6 of the movable lock tongue 5. The rebound pin 4 on the base part 3 automatically moves downward under an action of elastic force, and its bottom end penetrates the positioning hole 8 and is inserted into the adjustment hole 6 to fix the movable lock tongue 5. During a driving process of the vehicle, external air flows into the vehicle through the ventilation groove 7 in the middle of the base part 3, and enters the gap formed by the movable lock tongue 5 and the ventilation groove 7, thereby achieving ventilation and cooling.

(9) Referring to FIG. 2, the clamping part 1 is Z-shaped. The clamping part 1 includes a first horizontal section 11, an inclined section 10, and a second horizontal section 9 that are sequentially connected to form a multi-angle structure. When the vehicle door is closed, it conforms to the contour of the U-shaped door lock of the vehicle body. An end of the second horizontal section 9 is fixedly connected with a hook-shaped protrusion 2 that is inwardly bent, which is embedded in an interior of the U-shaped door lock to form a stable embedded buckle connection, which prevents the door lock from loosening and falling off during vehicle driving. A parallel distance between the base part 3 and the movable lock tongue 5 is six millimeters, which reserves space for the expansion and contraction adjustment of the movable lock tongue 5. A user can increase or decrease the distance according to actual needs to control the ventilation volume and meet the ventilation needs in different scenarios.

(10) Referring to FIG. 1, the base part 3 is made of aluminum alloy material, which has good corrosion resistance for the base part 3 and is used to resist the erosion of the base part 3 by the external environment. The aluminum alloy has high strength and can withstand the vibration and external forces during vehicle driving, rendering it less prone to deformation and damage, and extending the service life of the base part 3. An axis of the base part 3 is parallel to an axis of the movable lock tongue 5 to avoid displacement or jamming.

(11) Referring to FIG. 2, an aperture of adjustment hole 6 is the same as that of positioning hole 8, and their central axes coincide. The movable lock tongue 5 is not easily loosened or displaced after being fixed, maintaining the stability of the ventilation opening size and ensuring the ventilation effect.

(12) In an implementation mode, an axis of the second horizontal section 9 is perpendicular to an axis of the hook-shaped protrusion 2, which can decompose an impact force into a support force of the horizontal section and a pulling force of the hook-shaped protrusion 2, avoiding loosening caused by single point force and improving the bite strength between the clamping part 1 and the vehicle door lock.

(13) Working principle: when in use, the base part 3 is first placed against the inner wall of the vehicle door, so that the Z-shaped structure formed by the first horizontal section 11, inclined section 10, and second horizontal section 9 of the clamping part 1 corresponds to a contour of the U-shaped door lock of the vehicle body. When the vehicle door is closed, the hook-shaped protrusion 2 at the end of the second horizontal section 9 is embedded into an interior of the U-shaped door lock, thereby completing an initial fixation of the door lock. When adjusting the ventilation volume, the movable lock tongue 5 is manually pulled to slide inside the ventilation groove 7. The adjustment hole 6 on the movable lock tongue 5 changes position along with the movement. When an appropriate ventilation hole size is selected, the rebound pin 4 is automatically popped into an aligned positioning hole 8 and the adjustment hole 6, thereby fixing the movable lock tongue 5. The aluminum alloy base part 3 maintains structural stability, and the movable lock tongue 5 and the base part 3 maintain a parallel distance of six millimeters to form a ventilation channel. The external air enters the vehicle through the gap between the ventilation groove 7 and the movable lock tongue 5.
