Problems solved by technology

[0003] Pure electric new energy vehicles do not have manual transmission and can only be shifted through automatic transmission. When the vehicle needs to change gears when driving on a slope, it is necessary to pull the handbrake first to stop the vehicle before changing gears. If the driver makes a mistake, it will cause The gearbox and engine are subjected to a large force, which may damage the gearbox and engine, and when the vehicle is powered off or malfunctions, the existing technology cannot guarantee that the vehicle is in the P position
[0004] Therefore, invent a new energy vehicle shift lock and parking assistance mechanism that can ensure that the vehicle shifts gears when the brakes are stepped on, and can automatically return to the P gear to assist parking when the vehicle is powered off or fails. It is necessary to solve the above-mentioned problems that the driver is prone to operating errors when shifting gears, and the vehicle cannot be guaranteed to return to the P gear state when the vehicle is powered off or fails.

Embodiment 1

[0045] A new energy vehicle shift lock and parking assistance mechanism, such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 with Figure 9 As shown, it includes an outer frame 1, a protective frame 2, a first fixed shaft 3, a second fixed shaft 4, a rotating rod 5, a gear handle 6, a torsion spring 7, a first locking assembly 8, a shifting assembly 9 and a second Two locking components 10, the outer top right side of the outer frame 1 is connected with the protective frame 2 by welding, the inner rear side of the outer frame 1 is fixedly connected with the first fixed shaft 3, and the inner front side of the outer frame 1 is fixedly connected with the second fixed shaft The shaft 4, the first fixed shaft 3 and the second fixed shaft 4 are jointly rotatably connected with a rotating rod 5, and the rotating rod 5 is slidably matched with the outer frame 1, and the upper part of the rotating rod 5 is fixedly connected with a ge...

Embodiment 2

[0051] On the basis of Example 1, such as Figure 10 , Figure 11 with Figure 12 As shown, it also includes a parking back gear assembly 11. The parking back gear assembly 11 is arranged on the first fixed shaft 3. The parking back gear assembly 11 is used to reset the shift lever 94 to the P position when the power is cut off. The parking backstop assembly 11 includes an arc-shaped magnetic block 111, a second fixed rod 112, a first coil spring 113, a circular magnetic block 114, a third fixed rod 115, a fixed frame 116, a rotating shaft 117, a hand brake lever 118, Flat gear 119, sliding guide frame 1111 and second tooth bar 1112, first fixed shaft 3 bottoms are slidably connected with arc-shaped magnetic block 111, and arc-shaped magnetic block 111 has magnetism, and the upper part of sliding bar 93 is fixedly connected with second fixed Rod 112, the second fixed rod 112 is located inside the first fan-shaped plate 92, the first coil spring 113 is connected between the s...

Embodiment 3

[0054] On the basis of Example 2, such as Figure 13 As shown, a labor-saving assembly 12 is also included, and the labor-saving assembly 12 is arranged on the first slider 81. The labor-saving assembly 12 is used to reduce the force of the driver when pressing the locking block 82. The labor-saving assembly 12 includes a fixed block 121 and a roller 122. A pair of fixed blocks 121 are connected to the side of the first slider 81 away from the locking block 82 by welding. The fixed blocks 121 are rotatably connected with rollers 122 , and the rollers 122 cooperate with the wedge block 84 in a rolling manner.

[0055] When the locking block 82 is pressed, the roller 122 rolls on the wedge-shaped block 84, so that the locking block 82 can be pressed more easily, which saves effort.

Abstract

The invention relates to the field of new energy automobiles, in particular to a new energy automobile gear shifting locking and parking auxiliary mechanism which comprises an outer frame, a protection frame, a first fixing shaft, a second fixing shaft, a rotating rod and the like. The protection frame is fixedly connected to the right side of the outer top of the outer frame, the first fixing shaft is fixedly connected to the rear side in the outer frame, the second fixing shaft is fixedly connected to the front side in the outer frame, and the rotating rod is rotationally connected between the first fixing shaft and the second fixing shaft. When a vehicle is powered off or breaks down and is parked, a driver manually pulls a hand brake rod, an arc-shaped magnetic block can attract a circular magnetic block and a device on the circular magnetic block upwards through magnetic force, a sliding clamping rod does not limit a gear shifting rod any more, and then a torsion spring can reset and drive a rotating rod and a device on the rotating rod to reset; therefore, the shift lever automatically returns to the P gear, and auxiliary parking can be facilitated.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a new energy vehicle shift lock and parking assistance mechanism. Background technique [0002] Under the pressure of energy and environmental protection, new energy vehicles will undoubtedly become the development direction of future automobiles. New energy vehicles are mainly driven by electricity. New energy vehicles themselves do not emit harmful gases that pollute the atmosphere and do not pollute the environment. Therefore, new energy vehicles occupy Great advantages, and new energy vehicles have great potential for development. [0003] Pure electric new energy vehicles do not have manual transmission, and can only be shifted through automatic transmission. When the vehicle needs to change gears when driving on a slope, it is necessary to pull the handbrake first to stop the vehicle before changing gears. If the driver makes a mistake, it will cause The gearbox and the ...
