Problems solved by technology

[0004] The electronic shifter of this structure, when the car breaks down and needs to be towed, the electronic shifter of this structure cannot be put out of the P gear, and it is necessary to arrange a separate cable structure in the cab or use special tools in the engine compartment. The car can be mechanically released from the P gear, so that the car can be towed, but the separate arrangement of the cable structure in the cab will increase the cost and increase the difficulty of layout. Due to the complex structure and many heat sources of the engine compartment, it is easy to be burned and scratched for unfamiliar users, and there are certain safety hazards

Embodiment 1

[0029] like figure 1 , figure 2 As shown, the shifter includes a rotating shaft 1, a first joystick 2 responsible for R-N-D gear switching, a second joystick 3 and a housing 10 responsible for M-M+-M-switching, the first joystick 2 and the second joystick 3 can rotate around the rotating shaft 1 to switch gears. The mechanical P-out device includes a cable 4, a stopper 7, and the other end of the cable 4 is provided between the first joystick 2 and the second joystick 3 when the first joystick 2 and the second joystick 3 are synchronized. A connection structure that can pull the drag cable 4 to move when rotating around the rotating shaft 1 .

[0030] The stopper 7 includes a straight main body 71 and a stopper 72, the stopper 72 protrudes and is fixedly connected to the bottom of the main body 71, and the top of the main body 71 is hingedly positioned with the housing 10. In this embodiment, the stopper 7 is used to limit the displacement of the first joystick 2, and the ...

Embodiment 2

[0034] The structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that in this embodiment, the limiting member 7 includes a pin shaft, the pin shaft is passed through the casing 10, and the inner end of the pin shaft can move to the first position. The first joystick 2 is limited on the movement path of the joystick 2. In actual production, the pin shaft can be used to limit the displacement of the second joystick 3, or the pin shaft can be used to limit the first joystick 2 and the first joystick 2 at the same time. Displacement of the second joystick 3.

Abstract

The invention provides a mechanical gear shifting device for a gear lever type electronic gear shifter, which belongs to the technical field of automobile gear shifters. It solves the problem that the existing electronic gear shifter cannot mechanically go out of the P gear. The shifter includes a rotating shaft, a first joystick responsible for R-N-D gear switching and a second joystick responsible for M-M+-M-switching, both the first joystick and the second joystick can rotate around the shaft Turn to switch gears. The mechanical P gear device includes a cable and a limiter for limiting the displacement of the first joystick and / or the second joystick. One end of the rope is used to connect the P gear rocker arm of the automobile transmission. A connecting structure capable of pulling the cable to move is provided between the other end of the cable and the first joystick and the second joystick when the first joystick and the second joystick rotate around the rotation axis synchronously. The gear lever type electronic gear shifter can mechanically shift to the P gear.

Description

technical field [0001] The invention belongs to the technical field of automobile gear shifters, and relates to a mechanical P gear shifting device of a gear lever type electronic gear shifter. Background technique [0002] With the development of intelligence, electrification and light weight in the automobile industry, electronic shifters are used more and more. Electronic shifters realize shifting by converting the action of the driver's operating handle into electrical signals and transmitting them to the transmission. block intent. [0003] Existing electronic shifters, for example, Chinese patent literature discloses lever-type electronic shifters and automobiles [application number: 201910146850.5; authorized announcement number: CN109812574B], which includes a shift lever assembly, a sensor module, and an electronic control unit and M / S gear button; the shift lever assembly is in the form of a five-position monostable state. When the shift lever assembly is moved to...
