Trunk lock of automobile

Abstract

The invention provides a trunk lock of an automobile, which belongs to the technical field of automobiles and solves the technical problems of relatively complicated drive mechanism arranged between a motor and a starting arm, incompact structure, relatively large space occupation and the like. The trunk lock of the automobile comprises a shell and a stay wire of which one end is penetrated through the shell, wherein the motor is fixedly arranged on the shell and a swing arm is hinged with the shell. The trunk lock of the automobile is characterized in that: the shell is also hinged with a spring bolt; one end of the spring bolt extends to the outside part of the shell, and the other end of the spring bolt has a shifting block I and a shifting block II respectively; a drive mechanism capable of pushing the shifting block I to move when the motor rotates is arranged between the motor and the shifting block I; the swing arm is connected with the stay wire, and the swing arm is placed against the shifting block II and pushes the shifting block II to move when the stay wire is pulled. The device has high physical transfer performance and runs stably; the drive mechanism is simpler andcompacter in structure; and the spring bolt, the shifting block I and the shifting block II are designed respectively, so that the processing of the spring bolt is improved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a luggage compartment lock of an automobile. Background technique [0002] The back of the car is provided with a trunk that can place tires or other objects. The trunk includes a lid and a wall. An opening mechanism and a locking mechanism that can manipulate the flipping of the lid are provided between the lid and the wall. The locking mechanism includes an installation The luggage compartment lock on the box wall used to need to use a key to open the luggage compartment lock, which is quite inconvenient to use, and the driver needs to get out of the car to open and close. [0003] In order to solve this problem, some manufacturers have designed an electric luggage compartment lock, such as a kind of electric luggage compartment lock disclosed in the patent (CN201133254Y), comprising a shell and an opening arm arranged on the shell, the opening arm is connected with a pull wi...

Problems solved by technology

However, this device also has disadvantages. The pull wire is directly connected to the opening arm, and the pull wire needs to form a certain angle with the opening arm, which greatly limits the installation position of the pull wire and makes it difficult to arrange the pull wire. The force is not ideal, the operation is unstable, and it is easy to get stuck after a long time of use. When the time comes, the pull wire cannot pull the opening arm

The transmission mechanism between the motor and the opening arm is relatively complicated, and the structure is not compact, which takes up a large space, increases the overall volume of the luggage compartment lock, and reduces the aesthetics of the luggage compartment lock
