The subsequent operator can directly fix the mounting plate with the unlocking module and the inertia lock module installed on the handle base. During assembly, there is no need to distinguish between the sequence of processes, and the unlocking module and the inertia lock module can be assembled on the handle base. The small assembly and the handle assembly can be processed simultaneously, and the assembly method is more flexible, thereby improving assembly efficiency. At the same time, it also greatly saves labor costs, which has the effect of effectively reducing labor costs and making the assembly method more flexible.

[0009] The utility model is further configured as follows: the installation slider includes a sliding portion and a stop portion, the stop portion is extended and arranged on both sides of the sliding portion, the sliding portion is guide-plugged with the installation groove, so that the stop portion and the installation groove are anti-detachment matched.

[0010] By adopting the above technical solution, when the installation slide block slides into the installation groove through the sliding portion, the stop portion can stop the inner wall of the installation groove, which can effectively prevent the installation plate from being separated from the handle base.

[0011] The utility model is further configured as follows: guide plug-in parts are provided on both sides of the mounting plate, slots are provided on the handle base corresponding to the plug-in parts, guide inclined surfaces are provided on the guide plug-in parts corresponding to the slots, and the guide plug-in parts are guide-connected with the corresponding slots through the guide inclined surfaces.

[0012] By adopting the above technical solution and adding the guiding inclined surface, the guiding plug-in portion can be guided and inserted into the slot without precise alignment with the slot, which is beneficial to improving the assembly efficiency and installation accuracy of the mounting plate on the handle base.

[0020] By adopting the above technical solution, in the initial state, the elastic reset component will drive the unlocking block away from the micro switch. When the car door needs to be unlocked, the unlocking block rotates and presses the micro switch, and at the same time drives the cable to be pulled. The door is unlocked through the linkage cooperation between the cable and the micro switch. When the door is unlocked, the elastic reset component drives the unlocking block away from the micro switch and resets it to the initial state.

[0021] The utility model is further configured as follows: the unlocking block is provided with a buffer block, the mounting plate is provided with a stopper corresponding to the buffer block, and the buffer block is stop-matched with the stopper.

The addition of the buffer block plays a role in buffering and shock absorption, and can effectively prevent the unlocking block from being reset by the elastic force of the elastic reset component. The impact force is too large, causing collision and damage between components.

[0023] The utility model is further configured as follows: the inertial lock module comprises an inertial block and an elastic reset member, the inertial block is rotatably connected to the mounting plate, and the elastic reset member always has a tendency to drive the inertial block away from the unlocking module.

[0024] By adopting the above technical solution, when the vehicle brakes suddenly or collides during driving, the inertia block will rotate due to the inertia force.
