Technical Field

[0001] This utility model relates to the field of automotive door lock technology, specifically an integrated door lock for automobiles. Background Technology

[0002] With the development of the automotive industry, the functions and types of automobiles are becoming increasingly diverse, and people's attention to and comprehensive requirements for automobiles are also gradually increasing. Among them, the car door lock is a component used for car doors and is an essential part of the functionality of automobiles. It can effectively connect the car body and the door, allowing the door to be locked or unlocked.

[0003] Forgetting to check outside before opening the car door can easily lead to tragedy. Therefore, it's best to use the hand furthest from the door when opening it. However, this two-handed opening motion isn't suitable for cars that are already in use. To overcome this, existing technology (Chinese patent application number 202421190225.3, application date 2024-05-29) describes a car safety door lock. When someone gets out of the car, the hand closest to the door rotates the handle, which drives a spool to rotate. The spool, via a steel cable, moves a pin to the right and disengages from the locking hole. Then, the handle is pulled normally, and the door opens. This invention has a clever structure, improving upon the most commonly used vehicle door lock mechanism to allow for two-handed opening of the door, reducing accidents and ensuring driving safety. However, the aforementioned car door lock structure is too simple, resulting in a less reliable locking limit and still posing a potential risk of accidents due to opening the door without checking outside.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on existing equipment. Therefore, we have proposed an integrated door lock for automobiles that can effectively solve these problems. Utility Model Content

The motor is located on the right side of the sliding plate, and a limit block is fixedly connected to the left output shaft of the motor. A through slot matching the shape and size of the limit block is provided on the sliding plate, and the output shaft of the motor passes through the through slot so that the limit block is vertically misaligned and engaged with the left side of the through slot.

[0010] Preferably, a support base is fixedly connected to the bottom end of the lock housing, and the right side of the fixing rod is fixedly connected to the support base.

[0011] Preferably, one end of the motor is provided with a heat dissipation component, the heat dissipation component includes a rotating rod rotatably connected to the inner end wall of the lock housing, and gears and multiple evenly distributed fan blades are fixedly connected to both ends of the outer wall of the door, and a rack is fixedly connected to the bottom end of the slide bar, and the gear meshes with the bottom of the rack.

[0012] Preferably, the bottom end of the slide rail located below has a groove to accommodate the rack at the bottom end of the slide bar as it slides along the groove.

[0013] Compared with existing technologies, the advantages of this utility model are as follows: This integrated door lock for automobiles, through the cooperation of the lock housing, locking pin, and unlocking components, uses a locking spring to push the slide bar to a fixed position, allowing the locking pin to be stably inserted into the car frame to lock the door. When the door needs to be opened, simply pull the door handle outward, and then use a steel cable to pull the slide bar and locking pin to the left, thus unlocking and opening the door. This door lock has a reasonable and stable structure, making the locking and limiting of the car door more reliable; at the same time, through the use of a secondary locking component, it can... To effectively avoid the potential risk of accidents caused by opening the car door without checking the outside of the car, the specific contents are as follows: (1) By cooperating with the lock housing, the lock pin and the unlocking component, the locking spring pushes the slide bar to fix the position, and the lock pin can be stably inserted into the car frame to lock the car door. When the car door needs to be opened, just pull the door handle to turn it outward, and then pull the slide bar and lock pin to the left by the steel wire rope to unlock and open the car door and the car frame. This door lock structure is reasonable and stable, making the locking limit of the car door more reliable.

[0014] (2) By installing thermal infrared human body sensors at the front and rear of the vehicle body, and by automatically turning on the sensors when the vehicle stops, pedestrians around can be monitored before getting off the vehicle.

[0015] (3) By setting up a secondary lock assembly, when the car is parked, if the thermal sensor detects a pedestrian, the motor stops and the limit block is stably locked on the left side of the sliding plate. In this way, even if the door handle is pulled, the door cannot be unlocked. When the sensor does not detect a pedestrian, the motor starts to drive the limit block to rotate so that it completely overlaps with the through groove. At this time, pulling the door handle can smoothly drive the slide bar and sliding plate to move to the left, so as to realize the leftward movement of the lock pin to unlock, thereby avoiding the situation of opening the car door rashly without observing the outside of the car and causing an accident.

[0016] (4) By setting up a heat dissipation component, the motor needs to be operated to unlock the secondary lock component every time the car door is opened. The slide bar will also move to the left to unlock the lock pin. When the slide bar moves, the rack moves synchronously, which in turn drives the bottom meshing gear to rotate. The rotating rod and fan blades rotate synchronously, so that the fan blades can blow air to cool the motor and extend its service life. Attached Figure Description

[0024] 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.

[0025] Example 1: Please refer to Figures 1-6 This utility model provides the following technical solution: an integrated door lock for automobiles, including a car door 1, with a door handle 3 rotatably mounted on the outer wall of the car door 1 via a storage groove 2; a lock housing 4 is provided on the inner side of the car door 1, and a locking pin 7 is slidably connected to the right side of the lock housing 4, and the locking pin 7 continues to extend to the outer side of the car door 1 and is inserted into the car frame; an unlocking component is provided inside the lock housing 4, the unlocking component including two slide rails 5 fixedly connected to the inner end wall of the lock housing 4, a slide bar 6 slidably connected between the two slide rails 5, and the locking pin 7 fixedly connected to the right side of the slide bar 6. A steel wire rope 8 is fixedly connected between the left side of the slide bar 6 and the left opening end of the door handle 3. A fixing rod 10 is fixedly connected to the left inner wall of the lock housing 4. A sliding plate 12 is fixedly connected to the bottom end of the slide bar 6, and the sliding plate 12 slides on the outside of the fixing rod 10. A locking spring 11 is fixedly connected between the sliding plate 12 and the left inner wall of the lock housing 4. A support base is fixedly connected to the bottom end of the lock housing 4, and the right side of the fixing rod 10 is fixedly connected to the support base to ensure the connection stability of the fixing rod 10 and the stability of the sliding plate 12 sliding along its outside.

[0026] Through the cooperation of the lock housing 4, the locking pin 7 and the unlocking component, the locking spring 11 pushes the slide bar 6 to a fixed position, and the locking pin 7 can be stably inserted into the car frame to lock the car door 1. When the car door 1 needs to be opened, simply pull the door handle 3 to turn it outward. The opening end of the door handle 3 will pull the steel cable 8 to the left. The steel cable 8 continues to pull the slide bar 6 to move to the left along the slide rail 5. The locking pin 7 moves synchronously and retracts into the lock housing 4. A guide rod 9 is fixedly connected between the two slide rails 5, and the steel cable 8 passes around the guide rod 9 to form a right angle. This makes the traction force on the steel cable 8 when the door handle 3 is opened outward converted by the guide rod 9 into the direction of movement of the slide bar 6 along the slide rail 5. This makes the movement and unlocking of the slide bar 6 and the locking pin 7 smoother, thus realizing the unlocking and opening between the car door 1 and the car frame. This door lock structure is reasonable and stable, making the locking and limiting of the car door 1 more reliable.

[0027] Example 2: Based on Example 1, thermal infrared human body sensors are installed at both the front and rear ends of the vehicle body, and these sensors automatically open when the vehicle stops. The lock housing 4 is equipped with a secondary lock assembly to avoid the potential risk of accidents caused by opening the car door 1 without checking the outside of the vehicle. The secondary lock assembly includes a motor 13 fixedly installed at the bottom of the lock housing 4. The motor 13 is located on the right side of the sliding plate 12, and the left output shaft of the motor 13 is fixedly connected to a limit block 14. The sliding plate 12 has a through groove 15 that matches the shape and size of the limit block 14, and the output shaft of the motor 13 passes through the through groove 15 so that the limit block 14 is vertically misaligned and locked to the left side of the through groove 15.

[0028] By setting up a secondary lock assembly, when the vehicle is parked, the thermal infrared human body sensor automatically activates and detects human presence in front of and behind the vehicle. If a pedestrian is detected, the motor 13 stops, causing the limit block 14 to be stably engaged with the left side of the sliding plate 12, preventing the sliding plate 12 from moving to the left. The same applies to the slide bar 6 and the locking pin 7. Thus, even if the door handle 3 is pulled outward, the door 1 cannot be unlocked. When the sensor does not detect a pedestrian, it sends an electrical signal to the central control system to start the motor 13. The motor 13 drives the limit block 14 to rotate so that it completely overlaps with the through groove 15. At this time, pulling the door handle 3 moves the slide bar 6 and the sliding plate 12 to the left. The sliding plate 12 can then slide to the left along the outside of the limit block 14 through the through groove 15, thereby enabling the locking pin 7 to move to the left and unlock. This avoids the situation where the door 1 is opened rashly without observing the outside of the vehicle, which could lead to an accident.

[0029] In addition, a heat dissipation component is provided at one end of the motor 13. The heat dissipation component includes a rotating rod 16 rotatably connected to the inner end wall of the lock housing 4. Gears 18 and multiple evenly distributed fan blades 17 are fixedly connected to both ends of the outer wall of the door 1. A rack 19 is fixedly connected to the bottom end of the slide bar 6, and the gear 18 meshes with the bottom of the rack 19. A groove is provided at the bottom end of the slide rail 5 below to accommodate the rack 19 at the bottom end of the slide bar 6 to slide along the groove. Each time the door 1 is opened, the motor 13 needs to operate to unlock the secondary lock assembly. The slide bar 6 will also move to the left to unlock the lock pin 7. When the slide bar 6 moves, the rack 19 moves synchronously, which drives the gear 18 meshing at the bottom to rotate. The rotating rod 16 and the fan blades 17 rotate synchronously. In this way, the fan blades 17 can blow air to cool the motor 13 to extend its service life.
