Embodiment 1

[0039] see figure 1 with figure 2 , the embodiment of the present invention provides a lock assembly, including: a reinforcement plate 101 fixedly installed in a set area of ​​the vehicle body, and a reinforcement plate 101 arranged in the area opposite to the reinforcement plate 101 of the vehicle body, connected to the reinforcement plate by at least two bolts 101 is fixedly connected to the buckle, and the reinforcing plate 101 is located on the inside of the vehicle body, and the lock buckle is located on the outside of the vehicle body.

[0040] During specific implementation, first, the reinforcing plate 101 is installed on the set area inside the vehicle body. The set area mentioned here includes but not limited to the side wall outer panel 104 of the vehicle body, the C-pillar inner panel 102, and / or the outside of the rear wheel house. plate 103, and then install the buckle on the outside of the vehicle body, and be fixedly connected with the reinforcing plate 101 b...

Embodiment 2

[0049] An embodiment of the present invention also provides a locking mechanism, including: a door lock, matching with the door lock, and the lock assembly mentioned in Embodiment 1. During specific implementation, the door lock is installed on the door opening side of the rear door, and the lock assembly is installed on the set position of the vehicle body; when the rear door is closed, the door lock cooperates with the lock assembly to lock the rear door on the vehicle body. Utilizing the reinforcing plate in the above-mentioned lock assembly can increase the static stiffness and dynamic stiffness of the connection area between the vehicle body and the lock, so that the high-frequency components in the door-closing sound issued when the door is closed are reduced, the low-frequency components are increased, and the door-closing sound becomes muffled, thereby Improved the sound quality of closing doors.

Embodiment 3

[0051] The embodiment of the present invention also provides an automobile, including: a vehicle body, a door installed on the vehicle body, and the locking mechanism mentioned in Embodiment 2, wherein the door lock of the locking mechanism is installed on the door opening side of the vehicle door, and the locked The locking assembly of the mechanism is installed in the set area of ​​the vehicle body. For example, when the above-mentioned locking mechanism is used at the rear door of the automobile, after the rear door is closed, the door lock of the locking mechanism cooperates with the latch assembly to lock the rear door on the vehicle body. Utilizing the reinforcing plate in the above-mentioned lock assembly can increase the static stiffness and dynamic stiffness of the connection area between the vehicle body and the lock, so that the high-frequency components in the door-closing sound issued when the door is closed are reduced, the low-frequency components are increased, ...

Abstract

The invention provides a latch component, a locking mechanism and a vehicle, and relates to the technical field of vehicle manufacturing. The latch component comprises a reinforcement plate fixedly mounted in a set area of a vehicle body, and a latch arranged in an area, opposite to the reinforcement plate, of the vehicle body and fixedly connected with the reinforcement plate through at least two bolts, wherein the reinforcement plate is positioned at the inner side of the vehicle body; and the latch is positioned at the outer side of the vehicle body. The latch component, provided by the invention, can improve static stiffness and dynamic stiffness of the connected area of the vehicle body and the latch, so that high-frequency components in door closing sound generated in the closing of a vehicle door are decreased, low-frequency components are increased, the door closing sound is deep, and the quality of the door closing sound is improved. The locking mechanism comprises the latch component provided by the invention; and the vehicle comprises the locking mechanism provided by the invention.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a lock assembly, a locking mechanism and an automobile. Background technique [0002] At present, the car door of automobile can be divided into according to the opening mode: forward-opening car door, reverse-opening car door, horizontal moving car door, lift-up car door and folding car door. No matter what kind of opening method is adopted, a locking mechanism needs to be set between the car door and the vehicle body to lock the car door on the vehicle body when the car door is closed. Specifically, the locking mechanism usually includes a matched door lock and a catch, wherein the door lock is installed on the door, and the catch is installed on the side panel of the vehicle body. When the door is closed, the door lock and the catch are used to The locking between the doors locks the car body. [0003] However, due to the low strength of the side panel of th...
