Description

Technical Field

[0001] This utility model relates to the field of all-terrain door lock technology, specifically to an all-terrain ventilated door lock. Background Technology

[0002] As a special type of vehicle, all-terrain vehicles often operate in harsh environments with high temperatures and dust. Their doors are usually designed to be airtight to ensure safety, but this also leads to problems such as poor ventilation and excessively high temperatures inside the vehicle.

[0003] To solve this problem, ventilated door lock devices have emerged on the market. By adding a ventilation structure between the car door and the door lock, outside air can enter the car through specially designed vents, improving the driving environment.

[0004] However, existing ventilated door lock devices, due to their fixed vent size, cannot adapt to the needs of different car models. For models with thicker doors, the gap between the vent and the door lock is too large, causing the locking part to fail to engage effectively. This not only fails to form a stable ventilation channel but may also cause the ventilated door lock to shake violently during driving due to excessive installation gaps, accelerating component wear and even causing it to fall off. On the other hand, for models with thinner doors, the vent size is too large, resulting in insufficient adjustment range of the movable latch, which cannot fully close the door, compromising the door's airtightness and allowing external debris such as sand and rainwater to easily enter the vehicle, while also increasing wind noise.

[0005] To address these issues, we designed an all-terrain ventilated door lock. Utility Model Content

[0006] The purpose of this invention is to provide an all-terrain ventilated door lock to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides an all-terrain ventilated door lock, including a base portion, a snap-fit ​​portion integrally formed on one side of the base portion, a ventilation groove through the middle of the base portion, a positioning hole on the ventilation groove, a spring-loaded pin installed on the base portion, a movable locking tongue inside the ventilation groove, an adjustment hole spaced apart on the movable locking tongue, and the bottom end of the spring-loaded pin through the positioning hole and inserted into the adjustment hole.

[0008] Furthermore, the snap-fit ​​portion is Z-shaped and includes a first horizontal segment, an inclined segment, and a second horizontal segment connected in sequence. The end of the second horizontal segment is fixedly connected with an inwardly bent hook-shaped protrusion.

[0009] Furthermore, the base portion is made of aluminum alloy.

[0010] Furthermore, the axis of the base portion is parallel to the axis of the movable locking tongue.

[0011] Furthermore, the adjustment hole and the positioning hole have the same diameter, and their central axes coincide.

[0012] Furthermore, the parallel distance between the base portion and the movable locking tongue is six millimeters.

[0013] Furthermore, the axis of the second horizontal segment is perpendicular to the axis of the hook-shaped protrusion.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by setting a ventilation slot and a telescopic adjustable movable latch, the adjustment holes distributed at intervals on the movable latch cooperate with the positioning holes on the ventilation slot, and the telescopic positioning is achieved by using a spring-loaded pin, so that the size of the ventilation opening can be flexibly adjusted according to the door thickness and door lock spacing of different vehicle models, solving the problem that the existing ventilation door lock device cannot be adapted to different vehicle models due to its fixed size, and improving the versatility and practicality of the all-terrain ventilation door lock.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: By setting a multi-angle structure formed by sequentially connecting a first horizontal segment, an inclined segment, and a second horizontal segment, it conforms to the contour of the U-shaped door lock when the door is closed. Compared with the traditional flat snap-fit ​​structure, this increases the contact area and snap-fit ​​stability. The hook-shaped protrusion bent inward at the end of the second horizontal segment can be embedded inside the U-shaped door lock, forming an embedded snap-fit ​​connection similar to a hook. When the vehicle is traveling on bumps, this structure can utilize the mechanical interlocking effect between the hook-shaped protrusion and the U-shaped door lock to resist lateral and longitudinal displacement forces, improving the connection reliability and safety of the all-terrain ventilated door lock under complex road conditions.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution: an all-terrain ventilated door lock, including a base part 3, which is flat and fixedly connected to the inner wall of the door. A snap-fit ​​part 1 is integrally formed on one side of the base part 3. A ventilation groove 7 is opened through the middle of the base part 3. A positioning hole 8 is opened on the ventilation groove 7. A spring-loaded pin 4 is installed on the base part 3. A movable locking tongue 5 is provided inside the ventilation groove 7. An adjustment hole 6 is opened on the movable locking tongue 5 at intervals. It cooperates with the positioning hole 8. The extension and retraction positioning of the movable locking tongue 5 is realized by the spring-loaded pin 4. The bottom end of the spring-loaded pin 4 passes through the positioning hole 8 and is inserted into the adjustment hole 6.

[0023] In practice, the flat base 3 is placed against the inner wall of the door, with the latching part 1 facing the door lock. When the door is closed, the latching part 1 interacts with the door lock to achieve initial fixation. When ventilation needs adjustment, the movable latch 5 is manually pulled, allowing it to slide within the ventilation groove 7. The adjustment holes 6 spaced apart on the movable latch 5 move accordingly. Depending on the required ventilation opening size, the movable latch 5 is positioned appropriately. At this point, the positioning hole 8 on the ventilation groove 7 of the base 3 aligns with one of the adjustment holes 6 on the movable latch 5. The spring-loaded pin 4 on the base 3 automatically moves downwards under spring force, its bottom end passing through the positioning hole 8 and inserting into the adjustment hole 6, thus fixing the movable latch 5. During vehicle operation, outside air flows into the vehicle through the ventilation groove 7 in the middle of the base 3, entering the vehicle through the gap formed between the movable latch 5 and the ventilation groove 7, achieving ventilation and cooling.

[0024] See Figure 2 The latching part 1 is Z-shaped and includes a first horizontal section 11, an inclined section 10, and a second horizontal section 9 connected in sequence, forming a multi-angle structure. When the door is closed, it conforms to the contour of the U-shaped door lock on the vehicle body. The end of the second horizontal section 9 is fixedly connected to an inwardly bent hook-shaped protrusion 2, which, by embedding into the interior of the U-shaped door lock, forms a stable embedded latch connection, preventing the door lock from loosening and falling off during vehicle operation. The parallel distance between the base part 3 and the movable latch 5 is six millimeters, providing space for the extension and retraction adjustment of the movable latch 5. Users can increase or decrease the distance according to actual needs to control the amount of ventilation and meet the ventilation needs in different scenarios.

[0025] See Figure 1The base part 3 is made of aluminum alloy, which gives it excellent corrosion resistance, protecting it from external environmental erosion. Furthermore, the high strength of aluminum alloy allows it to withstand vibrations and external forces during vehicle operation, preventing deformation and damage and extending the service life of the base part 3. The axis of the base part 3 is parallel to the axis of the movable locking tongue 5 to prevent misalignment or jamming.

[0026] See Figure 2 The adjustment hole 6 and the positioning hole 8 have the same diameter and their central axes coincide. After the movable locking tongue 5 is fixed, it is not easy for it to loosen or shift, so as to keep the size of the ventilation opening stable and maintain the ventilation effect.

[0027] In specific implementation, based on the above implementation, the axis of the second horizontal segment 9 is perpendicular to the axis of the hook-shaped protrusion 2, which can decompose the impact force into the supporting force of the horizontal segment and the hooking force of the hook-shaped protrusion 2, avoiding loosening caused by single-point force and improving the engagement strength between the snap-fit ​​part 1 and the vehicle door lock.

[0028] Working principle: In use, first place the base part 3 against the inner wall of the car door, so that the Z-shaped structure formed by the first horizontal section 11, the inclined section 10 and the second horizontal section 9 of the locking part 1 corresponds to the outline of the U-shaped door lock on the car body. When the car door is closed, the hook-shaped protrusion 2 at the end of the second horizontal section 9 is embedded into the U-shaped door lock, completing the initial fixation of the door lock. When adjusting the ventilation volume, manually pull the movable latch 5 to make it slide in the ventilation groove 7. The adjustment hole 6 on the movable latch 5 changes position as it moves. When a suitable ventilation opening size is selected, the spring-loaded pin 4 automatically springs into the aligned positioning hole 8 and adjustment hole 6, fixing the movable latch 5. The aluminum alloy base part 3 maintains structural stability. The movable latch 5 and the base part 3 maintain a parallel distance of six millimeters to form a ventilation channel. Outside air enters the car through the gap between the ventilation groove 7 and the movable latch 5.
