Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and relates to a gear shift lever, particularly a rotary automotive gear shift lever. Background Technology

[0002] As a type of electronic gear shifting mechanism, the rotary gear shift lever controls the gearbox shifting by simulating electronic signals, realizing intelligent and convenient gear shifting operation. The rotary gear shift lever is small in size and compact in structure, which can save center console space and bring more possibilities to the interior layout of the vehicle.

[0003] In existing rotary gear selector designs, the PCB board and light guide strip play indispensable roles as core components. In the precision system of the backlight module, the coordinated operation of the PCB board and light guide strip is particularly crucial. However, rotary gear selectors may encounter unexpected situations such as collisions during actual use. Such impacts can easily cause the light guide strip to loosen or even detach, thus affecting the user's normal operating experience. Especially in dimly lit environments, if the light guide strip fails, the user will have difficulty identifying the gear position, potentially leading to safety risks due to accidental gear selection. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing a securely installed rotary gear shift lever for automobiles.

[0005] The objective of this utility model can be achieved through the following technical solution: A rotary car gear shift lever includes a lower base, an upper base, a PCB board, and a gear shift panel mounted on the upper base. A rotary assembly is installed at the center of the lower and upper bases, and the rotary assembly is connected to the lower and upper bases by bolts. A waterproof silicone pad is provided between the upper and lower bases. The gear shift panel is characterized by having R (Reverse) keys, N (Neutral) keys, and D (Drive) keys respectively. The rotary assembly has a rotating frame with a rotating cover. A P (Park) key is located at the center of the rotating cover. The waterproof silicone pad has protrusions corresponding to the R, N, and D keys, and each protrusion has a through hole. A light guide strip for illuminating the gear shift keys is installed on the protrusion, and the light guide strip is installed within the through hole of the protrusion. The inner wall of the boss is equipped with a support ring with an opening, the light guide strip is provided with a fixing member for mounting on the support ring, and the inner wall of the boss is equipped with a snap-fit ​​unit.

[0006] In the aforementioned rotary car gear shift lever, the locking unit is provided with a fixing block, an elastic element, and a locking element installed on the elastic element, and a locking groove is provided on the inner wall of the light guide strip to facilitate the fixed installation of the locking element.

[0007] In the aforementioned rotary car gear shift lever, the waterproof silicone pad has an opening groove on one side of the boss, a rotating ring is installed on the rotating frame, and a paddle for adjusting the gear is installed on the rotating ring, and the paddle is fixedly placed in the opening groove.

[0008] In the aforementioned rotary gear shifter, the light guide strip has an inverted conical structure.

[0009] Compared with existing technologies, this rotary car gear shift lever provides installation space for the light guide strip through the boss. The support ring on the inner wall of the boss ensures that the light guide strip is installed firmly. The fixing block, elastic element and snap-fit ​​element on the snap-fit ​​unit cooperate with the snap-fit ​​groove on the inner wall of the light guide strip, realizing the quick installation and removal of the light guide strip, which greatly simplifies the later maintenance process.
