Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, and in particular to an electric vehicle gear shifting mechanism assembly. Background Technology

[0002] With the rapid development of electric vehicle technology, the way cars shift gears has also changed. Many electric vehicles use a rotary electronic gear shifter for gear shifting, which is generally used to control the switching between the three gears: R, N, and D.

[0003] Currently, the main structure of the rotary electronic gear shifting mechanism is integrated into the housing, with the shift knob located on top of the housing. The housing is usually fixed by the upper and lower housings snapping together. Due to the complex forces on the shift knob, the installation position and fixation reliability of the housing are very important. For example, patent CN207083066U discloses a rotary gear shifting mechanism assembly, which includes a bottom housing and a panel connected by snaps. The middle housing is fixed in the inner cavity formed by the bottom housing and the panel by a spring pin and a spring. The housings are only connected by a simple snap-fit, resulting in relatively weak stability. After long-term use, it is easy to loosen, which affects the quality of electric vehicle use.

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0021] like Figures 1 to 5 As shown, the electric vehicle gear shifting mechanism assembly includes a base 4, a housing, and a gear shifting operation knob 3 mounted on the housing. Gear shifting is achieved by rotating the gear shifting operation knob.

[0022] The housing includes a matching upper housing 2 and a lower housing 1. The side of the lower housing is provided with mounting ears 101 for assembly mounting and fixing. The mounting ears are provided with fixing holes, and bolts are passed through the fixing holes to fix the housing to the vehicle bracket structure to achieve fixed installation.

[0023] An alignment structure is provided between the upper and lower shells for proper fit and alignment. Alignment clips are also provided on the outer walls of both the upper and lower shells for secure mounting and fixing. The fit between the upper and lower shells, as well as between the lower shell and the base, is achieved through these alignment structures. The upper and lower shells have staggered mounting clips, ensuring stable and reliable installation and preventing loosening over long-term use.

[0024] The bottom of the base 4 is provided with a connection slot 401, which is connected to the shift harness plug; the top of the base is located inside the lower housing, the side of the base is provided with a base side clip, and the lower housing is provided with a lower housing clip hole that mates with the base side clip. The lower housing and the base are positioned by a snap-fit.

[0025] Furthermore, an inner step 107 is provided on the inner wall of the lower housing 1 corresponding to the top of the base, and an inner rib 108 is provided on the top surface of the base corresponding to the inner step. When the base and the lower housing are engaged, the base is inserted into the lower housing, and the base is pushed to the inner step and held in place by the inner step. Further positioning is achieved by the inner rib engaging with the slot on the top surface of the base. The structure is stable and reliable.

[0026] The upper shell, lower shell, and base are all square structures, and their fit is stable and reliable. Furthermore, the bottom side of the base is provided with side ribs, and the bottom side of the lower shell is provided with a base mating groove 103 that mates with the side ribs, which facilitates assembly and ensures a stable and reliable fit.

[0027] The upper housing 2 has an upper housing mounting alignment clip 201 on its outer side, and the lower housing has a lower housing mounting alignment clip 102 on its outer side. The upper and lower housing mounting alignment clips are staggered. By fitting the mounting alignment clips with the corresponding grooves of the bracket structure, the fit is secure and will not easily loosen during long-term use.

[0028] Furthermore, the upper housing is equipped with a vertical alignment clip, while the lower housing is equipped with a horizontal alignment clip; the vertical clip has a certain height in the vertical direction, and the horizontal clip has a certain length in the horizontal direction, achieving limitation in different directions, ensuring stability and reliability.

[0029] The lower housing has an outer step 104 on its top outer side, and the lower part of the upper housing is engaged with the outer step through a snap-fit ​​structure. The outer step has an installation alignment rib 105, and the upper housing has an upper housing installation alignment groove 202 that matches the installation alignment rib. The engagement is stable and reliable.

[0030] Furthermore, the top of the lower shell is provided with a notch 106 on the outer step to limit the position of the internal structure. The limiting structure is integrated and compact.
