Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology and relates to a rotary electronic gear shifter. Background Technology

[0002] A rotary electronic gear shifter is a gear control device used in vehicles. It uses a rotary knob to switch gears. Specifically, the driver can rotate the knob to select gears such as forward, reverse, neutral, and parking.

[0003] Rotary electronic gear shifters require precise tactile feedback during gear changes. Specifically, the knob passes through multiple positioning points during rotation, and a noticeable resistance is felt when the knob leaves these points. This design not only provides intuitive tactile feedback but also ensures the knob remains firmly in the selected gear, effectively locking and limiting its position. Although many electronic gear shifters currently use a bullet-shaped design for tactile feedback, this type of structure is relatively complex and requires significant installation space, making it unsuitable for rotary electronic gear shifters. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a rotary electronic gear shifter.

[0005] The objective of this utility model can be achieved through the following technical solution: a rotary electronic gear shifter, comprising:

[0006] The mounting base has a mounting hole and a mating surface facing the axial direction of the mounting hole. The mating surface is configured as a wavy curved surface structure.

[0007] A knob assembly includes a rotating base with a metal spring having at least one contact portion. The rotating base is rotatably mounted in the mounting hole, and the contact portion abuts against the mating surface. When the knob assembly is rotated, the contact portion slides on the mating surface.

[0008] Preferably, the mounting hole is configured as a stepped hole structure, and the mating surface is configured as the stepped surface portion of the mounting hole.

[0009] Preferably, the inner wall of the mounting hole has a radially protruding annular step block, and the mating surface is set as the end face of the annular step block.

[0010] Preferably, the mating surface includes an arc-shaped transition portion and a recessed portion, and the number of the arc-shaped transition portion and the recessed portion are both multiple, and the arc-shaped transition portion and the recessed portion are arranged alternately.

[0011] Preferably, the metal spring is configured as a wave spring, and the wave spring is circumferentially fixedly connected to the rotating seat.

[0012] Preferably, the metal spring is configured with a V-shaped structure, and the contact portion is located at the trough of the metal spring.

[0013] Preferably, the knob assembly further includes a mounting bracket, with both ends of the metal spring piece fixedly connected to the mounting bracket, and the mounting bracket fixedly connected to the rotating seat.

[0014] Preferably, the knob assembly further includes a crystal knob block, which is fixedly connected to the rotating base.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. A rotary electronic gear shifter is provided that utilizes a metal spring and a mating surface to generate shifting feel and positioning. When the rotary assembly is rotated, the contact part of the metal spring slides on the mating surface of the wave-shaped curved surface structure, thereby generating the corresponding operating feel. The contact part can stay at the trough of the mating surface to play a limiting role. The overall structure is simple and ingenious, and the installation space requirement is small.

[0017] 2. The mating surface includes multiple arc-shaped transition parts (peaks) and recesses (troughs), which are arranged alternately. The arc-shaped transition parts guide the contact part to slide from one recess to another, while the recesses act as stop grooves. The contact part can be embedded into the recesses to achieve the purpose of limiting and providing tactile feedback.

[0018] 3. By utilizing the interaction between the metal spring and the wavy mating surface to provide shifting feel and positioning function, only one mating surface needs to be set in the mounting hole. The design of the mating surface is also very simple and compact (as in Embodiment 1 or Embodiment 2). The structure and design of the metal spring only need to occupy a very small installation space (as in Embodiment 3 or Embodiment 4), which significantly reduces the requirement for installation space and achieves a compact design.

Detailed Implementation

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] like Figures 1 to 4 As shown, a rotary electronic gear shifter includes: a mounting base 100, which has a mounting hole 110 and a mating surface 130 facing the axial direction of the mounting hole 110, the mating surface 130 being configured with a wavy curved surface structure; a knob assembly 200, which includes a rotating base 210, the rotating base 210 having a metal spring 300, the metal spring 300 having at least one contact portion 310, the rotating base 210 being rotatably mounted in the mounting hole 110, the contact portion 310 being in contact with the mating surface 130; when the knob assembly 200 is rotated, the contact portion 310 slides on the mating surface 130.

[0026] Mounting base 100 is the fixed base of the gear shifter, and knob assembly 200 is the directly operated part (rotating part) of the gear shifter. The mating surface 130 is actually an annular surface located within the mounting hole 110, and the mating surface 130 faces the upper opening of the mounting hole 110 (i.e., towards the axial direction of the mounting hole 110). The mating surface 130 undulates in the circumferential direction, thus forming a wave-like curved surface structure. That is, the mating surface 130 has crest positions (i.e., arc-shaped transition portions 131) and trough positions (i.e., recessed portions 132). The arc-shaped transition portions 131 and recessed portions 132 are arranged alternately, meaning that there is an arc-shaped transition portion 131 between two adjacent recessed portions 132. The contact portion 310 on the metal spring 300 slides in contact with the mating surface 130. Because the metal spring 300 itself is elastic, it ensures that the contact portion 310 is always in contact with the mating surface 130.

[0027] When the user rotates the knob, the rotating base 210 rotates together with the metal spring 300 on it. Since the contact part 310 of the metal spring 300 is always in contact with the mating surface 130 and the contact part 310 moves along the wavy curved surface, the metal spring 300 is continuously compressed and released during the rotation of the rotating base 210. The rotating base 210 needs to provide torque to deform the metal spring 300 in order to rotate. Therefore, the knob assembly 200 can generate a resistance feel when rotating.

[0028] During actual gear shifting, the knob assembly 200 is initially stationary, and the contact portion 310 of the metal spring 300 is located in the recess 132 (trough) of the mating surface 130. When the user applies torque and begins to rotate the knob assembly 200, the contact portion 310 moves from one recess 132 to the adjacent arc transition portion 131 (crest), and the metal spring 300 is gradually compressed. In order to cross the arc transition portion 131, the metal spring 300 must be further deformed, which requires additional torque. Once the contact portion 310 successfully crosses the arc transition portion 131 and enters the next recess 132, the metal spring 300 quickly returns to its original shape and releases the stored energy. At this time, the user will feel a distinct "click" sound or tactile feedback.

[0029] A rotary electronic gear shifter is provided that utilizes a metal spring 300 and a mating surface 130 to collaboratively generate shifting feel and positioning. When the rotary assembly 200 is rotated, the contact portion 310 of the metal spring 300 slides on the wavy curved surface 130, thereby generating a corresponding operating feel. Furthermore, the contact portion 310 can stop at the trough of the mating surface 130 to play a limiting role. The overall structure is simple and ingenious, and requires less installation space.

[0030] Example 1:

[0031] In Embodiment 1, the mounting hole 110 is configured as a stepped hole structure, and the mating surface 130 is configured as the stepped surface portion of the mounting hole 110. A stepped hole means that the mounting hole 110 is not a circular hole of a single diameter, but has a stepped transition area between two different diameters, and the mating surface 130 is disposed on this stepped surface.

[0032] Example 2:

[0033] like Figures 1 to 3 As shown, in Embodiment 2, an annular step block 120 is formed by a radially protruding section on the inner wall of the mounting hole 110, and the mating surface 130 is set as the end face of the annular step block 120. The annular step block 120 is an annular structure formed by the inward protrusion of the inner wall of the mounting hole 110. The function of the annular step block 120 is to support and set the mating surface 130.

[0034] like Figure 2 , Figure 3 As shown, based on the above embodiment, the mating surface 130 includes an arc-shaped transition portion 131 and a recessed portion 132. There are multiple arc-shaped transition portions 131 and recessed portions 132, and the arc-shaped transition portions 131 and recessed portions 132 are arranged alternately.

[0035] The mating surface 130 includes multiple arc-shaped transition portions 131 (crests) and recesses 132 (troughs), which are arranged alternately. The arc-shaped transition portions 131 guide the contact portion 310 to slide from one recess 132 to another. The recesses 132 act as stop grooves, allowing the contact portion 310 to be inserted into them for limiting and providing tactile feedback. When the rotating seat 210 rotates, the contact portion 310 needs to pass through multiple recesses 132 and arc-shaped transition portions 131 to obtain tactile feedback. When the rotating seat 210 stops rotating, the contact portion 310 slides into the nearest recess 132 to achieve a limiting effect.

[0036] It should be noted that as the contact part 310 passes over the arc transition part 131, the metal spring 300 will undergo elastic deformation, generating a certain resistance to the rotating seat 210, so that the user can feel the resistance when shifting gears. Once the contact part 310 successfully passes over the arc transition part 131 and falls into the new recess 132, the metal spring 300 quickly returns to its original shape, releasing the stored energy, and the user will feel a clear "click" sound or tactile feedback.

[0037] Example 3:

[0038] In Embodiment 3, the metal spring 300 is configured as a wave spring, and the wave spring is circumferentially fixedly connected to the rotating seat 210.

[0039] A wave spring is a thin metal ring with multiple peaks and troughs (i.e., contact portions 310). The wave spring is fitted onto the rotating seat 210, and when the rotating seat 210 rotates, the wave spring rotates along with it.

[0040] Example 4:

[0041] like Figure 2 As shown, in Embodiment 4, the metal spring 300 is configured with a V-shaped structure, and the contact portion 310 is located at the trough of the metal spring 300.

[0042] It should be added that, in both Embodiment 3 and Embodiment 4, the metal spring 300 has a long service life due to its metal material and excellent elastic deformation capability, and is not easily damaged, and is also very simple to maintain and replace.

[0043] Furthermore, by utilizing the interaction between the metal spring 300 and the wavy mating surface 130 to provide shifting feel and positioning function, only one mating surface 130 needs to be provided in the mounting hole 110. The design of forming the mating surface 130 is also very simple and compact (as in Embodiment 1 or Embodiment 2). The structure and design of the metal spring 300 only need to occupy a very small installation space (as in Embodiment 3 or Embodiment 4), which significantly reduces the requirement for installation space and achieves a compact design.

[0044] Based on Embodiment 3, the knob assembly 200 also includes a mounting bracket 220, with both ends of the metal spring 300 fixedly connected to the mounting bracket 220, and the mounting bracket 220 fixedly connected to the rotating seat 210.

[0045] By introducing a mounting bracket 220 and fixing both ends of the metal spring 300 to the mounting bracket 220, while the mounting bracket 220 is fixedly connected to the rotating seat 210, this design ensures reliable fixation of the metal spring 300 and facilitates assembly. In actual assembly, both ends of the metal spring 300 are snapped onto the mounting bracket 220 using clips, and then the mounting bracket 220 is snapped into the rotating seat 210.

[0046] like Figure 1 , Figure 4 As shown, the knob assembly 200 also includes a crystal knob block 230, which is fixedly connected to the rotating base 210.

[0047] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0048] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0049] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0050] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
