Detailed explanation of car trunk lock technology
The utility model belongs to the technical field of automobile locks, in particular to a MIM Parts structure for car trunk locks.

Background technique
With the rapid popularization of automobiles, the applicability level of automobile interior equipment is constantly improving, and the requirements of many motor vehicle drivers for various functional parts in motor vehicles are also constantly increasing. The lock for the opening and closing parts of the car is an indispensable accessory part of the car. During the opening process of the lock, a certain pop-up force is required to separate the lock body and the buckle, so as to prevent the false lock state of the lock.
Most of the existing car trunk locks are unlocked by the remote control key and closed by manpower. In the process of manpower closing, it is easy to cause the lock to be closed tightly, resulting in a false lock state, resulting in unsafe items and passengers. Also, some car trunks are faster when opened, which is easy to cause harm to the human body.

Technical Realization Elements
In order to solve the existing Car trunk locks MIM Parts proposed in the above background technology, in the process of manual closing, the locks are easy to be closed tightly, resulting in a false lock state, resulting in unsafe items and passengers, and there are also car backups. The speed of opening the trunk is fast and the technical problem is easy to cause harm to the human body. The utility model provides a lock structure for the trunk of an automobile, which can prevent false locks in the trunk, ensure driving safety, and prevent When the trunk is opened, the speed of opening the door is too fast, which ensures the safety of personnel.

Technical Solutions
A lock structure for the trunk of an automobile, comprising: a slide bar; the rear side of the slide bar is a hollow structure, and the slide bar also includes a motor, a controller and a plug; the front side of the slide bar passes through a hinge A connecting rod is provided for connection and rotation, and the connecting rod also includes a telescopic rod and a connecting buckle; a fixed block is slidably arranged on the rear side of the sliding rod, and a trapezoidal chute is opened on the front side of the fixed block; A reminder device is installed slidingly in the trapezoidal chute on the side, and the front side of the reminder device is integrated with a trapezoidal slider, and the bottom of the reminder device is integrated with a joint, and the joint is a smooth circular structure; the top of the reminder device is fixed An alarm is installed; a proximity switch is fixedly installed on the front side of the fixed block, and the proximity switch and the alarm are elastically connected by a spring.
Further, a motor is installed on the inside of the rear side of the slide bar through bolts; the top of the motor is provided with a controller through electrical connection; the front side of the motor is connected with a plug.
Further, the top of the connecting rod is provided with a chute, and both sides of the chute on the top of the connecting rod are provided with a trapezoidal chute, and a telescopic rod is slidingly arranged in the chute; both sides of the telescopic rod are uniformly provided with a trapezoidal slider , and the top of the telescopic rod is integrally provided with a hook; the front side of the connecting rod is integrally provided with connecting buckles, and the two sets of connecting buckles are elastically connected by springs.
Further, the fixed block includes a base; the top of the fixed block is integrally provided with a base, and the top of the base is provided with screw holes; the fixed block also includes a hoop; the bottom of the fixed block is integrally provided with A ferrule, and the ferrule is provided with a round hole fitted with the slide bar; both sides of the round hole of the ferrule are provided with slotted holes fitted with the plug.
Compared with the prior art, the utility model has the following beneficial effects:
By being provided with a connecting rod, a sliding rod and an alarm device, the upper and lower ends of the two groups of connecting rods are respectively connected with the latch at the bottom of the trunk and the latch of the door when in use. When the door is closed, the connecting rod Shrink inward, push the slide bar into the rear side of the hoop, and push up the reminder device through the plug to turn off the alarm. At this time, you can know that the trunk is closed successfully. If the plug does not pass through the hoop, Just can't turn off reminding device, just can prevent the false lock phenomenon that trunk appears at this moment, thereby can prevent the potential safety hazard that trunk causes because not closing in the process of vehicle running.
By being provided with connecting rods, tension springs are arranged between the two groups of connecting rods, which can prevent the problem that the trunk door is opened too fast to cause injury to personnel at the trunk when the trunk is opened.
