Description

Technical Field

[0001] This utility model belongs to the technical field of gear shifting equipment, and specifically relates to a gear shifting structure. Background Technology

[0002] A gear shifter is a device used to switch gears, applied in scenarios where the operating status of equipment needs to be controlled by adjusting the gear. In existing technologies, rotary gear shifters generally employ a design where an encoder is integrated with the housing structure; rotating the knob triggers the encoder to generate an electrical signal, thus achieving the gear shifting function. This technology is widely used in rotary gear shifters in automotive electronics, industrial control, and other fields. However, with the increasing demand for diversified equipment functions and refined appearance designs, the shortcomings of traditional solutions are becoming increasingly apparent.

[0003] In traditional gear shifting devices, encoders typically employ fixed gears or grating structures. Their rotational damping and tactile feedback are predetermined by the mechanical design, making it impossible to flexibly adjust them according to different usage scenarios (e.g., automotive gear shift knobs may require a more pronounced "tactile feedback" to prevent accidental operation, while consumer electronics devices may require a lighter tactile feedback or different damping characteristics). Traditional encoders struggle to achieve both. Furthermore, encoders must be wave soldered onto a PCB board, a process requiring strict control of soldering temperature and time, which can easily lead to problems such as cold solder joints and short circuits, increasing production yield and costs. In addition, the standard dimensions of encoders (such as diameter and height) limit the ultra-thin, irregularly shaped designs of the knob housing, making it difficult to adapt to the compact and personalized aesthetic requirements of high-end devices. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a shifting structure to solve the problem mentioned in the background art, where the rotational damping of existing shifting devices is difficult to adjust due to the fixed encoder structure.

[0005] This utility model solves the above-mentioned technical problems through the following technical means:

[0006] A gear shifting structure, characterized in that it comprises:

[0007] The first PCB board has several external exposed copper plates.

[0008] A toothed plate is mounted on the first PCB board. The toothed plate has a hollowed-out circular space in the middle. The inner wall of the circular space is provided with a number of continuous concave teeth, and the concave teeth correspond one-to-one with the exposed copper.

[0009] A rotating structural component is rotatably mounted within the circular space of the toothed plate, and a limiting cavity is provided on the side of the rotating structural component facing the first PCB board.

[0010] An inner ring of exposed copper, wherein a plurality of such exposed copper elements are arranged in a circumferential array centered on the inner ring of exposed copper; and

[0011] An elastic component includes a first electrical connector, a spring, and a second electrical connector installed within the limiting cavity. The first electrical connector contacts the exposed copper of the inner ring, and the second electrical connector contacts one of the exposed copper rings. The spring connects the first electrical connector and the second electrical connector, and under the elastic force of the spring, the second electrical connector abuts against one of the recessed teeth.

[0012] In one possible implementation, at least one of the first electrical connector and the second electrical connector is a steel ball.

[0013] In one possible implementation, a rigid member is provided between the first electrical connector and the spring and / or between the second electrical connector and the spring.

[0014] In one possible implementation, the rigid member is a columnar structure.

[0015] In one possible implementation, the rigid member is a "T-type" / "I-type" structure.

[0016] In one possible implementation, when the rigid member contacts the steel ball, the side of the rigid member that contacts the steel ball is designed as a concave structure to accommodate the steel ball.

[0017] In one possible implementation, the second electrical connector is a steel ball, and the first electrical connector is a ring sleeve.

[0018] In one possible implementation, the rotating structural member has an opening communicating with the limiting cavity, and a cover plate is detachably installed at the opening.

[0019] In one possible implementation, the shifting structure further includes a second PCB board mounted on the rotating structural member, and the inner ring exposed copper is mounted on the second PCB board.

[0020] In one possible implementation, a knob is mounted on the rotating structure.

[0021] The beneficial effects of this utility model are:

[0022] By adopting the technical solution of this application, the rotational damping can be precisely adjusted by adjusting the spring force and the depth of the concave teeth of the second electrical connector; the user experience is improved by the mechanical feedback (sound and feel) generated when the second electrical connector falls into the concave teeth; by eliminating the encoder welding process and using the physical contact between the elastic component and the exposed copper of the PCB to achieve electrical connection, the welding process is reduced, and the production difficulty and cost are lowered; by eliminating the fixed structure limitation of the encoder, PCBs, gears and rotating structural components of any shape can be designed according to requirements, and the appearance of ultra-thin and irregularly shaped knob housings can be adapted.

[0039] Example 1

[0040] like Figures 1-4As shown, this application provides a shifting structure, including a first PCB board 100, a gear plate 200, a rotating structural component 300, an inner exposed copper ring 110, and an elastic component. The first PCB board 100 has a plurality of outer exposed copper rings 120 arranged in a circular array around the inner exposed copper ring 110. It should be noted that in one embodiment, the inner exposed copper ring 110 is located at the center of the circular array and is coaxial with each of the outer exposed copper rings 120. The inner exposed copper ring 110 can be integrated into the first PCB board 100 or independently disposed on a second PCB board 500 fixedly connected to it. Each inner exposed copper ring 110 is individually connected to a pin of the controller, and each outer exposed copper ring 120 is also connected to a pin of the controller. The toothed plate 200 is fixedly installed on the first PCB board 100. The toothed plate 200 has a hollowed-out circular space 210 in the middle. The inner wall of the circular space 210 is provided with a number of continuous concave teeth 220. The concave teeth 220 correspond one-to-one with the external exposed copper 120, that is, the number of concave teeth 220 and the external exposed copper 120 are the same, and the concave teeth 220 and their corresponding external exposed copper 120 are located in the same vertical direction.

[0041] The rotating structural component 300 is rotatably mounted within the circular space 210 of the toothed plate 200, and the rotating structural component 300 is circular in shape. A limiting structure can be added to the outside of the rotating structural component 300, ensuring that its movement is limited to rotation relative to the toothed plate 200. A limiting cavity 310 is provided on the side of the rotating structural component 300 facing the first PCB board 100. In one embodiment, the downward-facing side and the side facing the concave tooth 220 of the limiting cavity 310 are both open. The limiting cavity 310 extends radially along the rotating structural component 300, extending from the center to the side of the rotating structural component 300. Furthermore, in one embodiment, a knob 320 is mounted on the upper end of the rotating structural component 300.

[0042] The elastic component includes a first electrical connector 410, a spring 420, and a second electrical connector 430 installed within the limiting cavity 310. The first electrical connector 410 contacts the inner exposed copper ring 110, and the second electrical connector 430 contacts one of the outer exposed copper rings 120. The spring 420 connects the first electrical connector 410 and the second electrical connector 430, and under the elastic force of the spring 420, the second electrical connector 430 abuts against one of the recessed teeth 220. When the rotating structure 300 rotates, the elastic component moves with the rotating structure 300, and the second electrical connector 430 compresses the spring 420 and moves from one recessed tooth 220 to another. It should be noted that the elastic component as a whole provides an electrical connection, specifically connecting the inner exposed copper ring 110 to one of the outer exposed copper rings 120 via the first electrical connector 410, the spring 420, and the second electrical connector 430.

[0043] With the above technical solution, when gear shifting is required, the rotating structural component 300 can be directly rotated. By rotating the structural component 300, the position of the elastic component is moved, causing the second electrical connector 430 to move from one position of exposed copper 120 to another, thereby realizing gear shifting. It should be noted that the number of concave teeth 220 and exposed copper 120 can be set according to the actual number of gears, or it can be independent of the number of gears. For example, clockwise rotation shifts to increase the gear, and counterclockwise rotation shifts to decrease the gear.

[0044] This application enables precise adjustment of rotational damping by adjusting the elasticity of the spring 420 and the depth of the engagement between the second electrical connector 430 and the concave tooth 220; it enhances the user experience through the mechanical feedback (sound and feel) generated when the second electrical connector 430 falls into the concave tooth 220; it reduces the soldering process and lowers production difficulty and cost by eliminating the encoder soldering process and using physical contact between the elastic component and the exposed copper of the PCB to achieve electrical connection; and it allows for the design of PCBs, gears, and rotating structural components 300 of any shape according to requirements, adapting to the appearance of ultra-thin and irregularly shaped knob housings by eliminating the fixed structure limitation of the encoder.

[0045] Example 2

[0046] like Figures 1-6As shown, the elastic component in this embodiment is optimized based on Embodiment 1. Specifically, in this embodiment, at least one of the first electrical connector 410 and the second electrical connector 430 is a steel ball, and the inner side of the limiting cavity 310 is designed with a concave structure to accommodate the steel ball, thereby limiting the steel ball. With this arrangement, when the rotating structural component 300 drives the elastic component to move, the steel ball can roll on the first PCB board 100, converting sliding friction into rolling friction, thereby reducing the friction between the first electrical connector 410 and the second electrical connector 430 and the exposed copper.

[0047] It should be noted that the concave structure that mates with the steel ball can be positioned at the center of the rotating structural component 300, or it can be designed not to be at the center. For example... Figure 6 As shown, if the concave structure is located at the center of the rotating structural component 300, the contact area between the first electrical connector 410 and the inner exposed copper 110 will be smaller, the coverage area of ​​the inner exposed copper 110 will be reduced, and the loss of the inner exposed copper will be less. It is understood that in some embodiments, when structural or electronic components are to be designed at the center of the rotating structural component 300 or at the corresponding center position of the first PCB board 100, the inner exposed copper 110 can be designed as a ring, fitted around the outside of the central structural component or central electronic component.

[0048] Example 3

[0049] like Figures 5-7 As shown, the elastic component in this embodiment is an optimization based on Embodiment 2. The idea of ​​this embodiment is to shorten the spring 420 to reduce the spring 420's rebound time and enhance the damping feel. Specifically, a rigid component 440 is provided between the first electrical connector 410 and the spring 420 and / or between the second electrical connector 430 and the spring 420. The rigid component 440 is also made of a material that can achieve electrical conductivity, such as metal. That is, this embodiment has three structural forms: the first is that a rigid component 440 is provided between the first electrical connector 410 and the spring 420; the second is that a rigid component 440 is provided between the second electrical connector 430 and the spring 420; the third is that a rigid component 440 is provided between the first electrical connector 410 and the spring 420, and also between the second electrical connector 430 and the spring 420. All three methods can shorten the spring 420. In particular, the third method uses a symmetrical structure, which makes the elastic component more stable as a whole and less prone to being distorted.

[0050] In this embodiment, the rigid member 440 can be designed as a columnar structure, which can be hollow or solid. In addition, in order to make the contact between the rigid member 440 and the steel ball more stable, when the rigid member 440 contacts the steel ball, the side of the rigid member 440 that contacts the steel ball is designed as a concave structure to accommodate the steel ball.

[0051] It should be noted that, Figures 5-7 The structure shown here has various elastic components with different structures. This is only for the purpose of illustrating the idea of ​​this embodiment and reducing wasted space, and does not represent that the actual product is like this. The actual product should be different. Figures 1-4 The structure shown is similar, consisting of only one set of elastic components. The subsequent embodiments follow the same pattern and will not be described further.

[0052] Example 4

[0053] like Figures 5-7 As shown, the rigid component 440 in this embodiment is optimized based on Embodiment 3. In order to save more raw materials, the rigid component 440 in this embodiment can be designed as a "T-type" or "I-type" structure. These two structures obviously save more processing materials.

[0054] Furthermore, when the rigid component 440 has a "T-type" or "I-type" structure, the side of the rigid component 440 that contacts the steel ball can also be designed as a concave structure to accommodate the steel ball, making the connection between the rigid component 440 and the steel ball more stable.

[0055] Example 5

[0056] like Figure 7 As shown, the elastic component in this embodiment is optimized based on the first embodiment. Specifically, in this embodiment, the second electrical connector 430 is a steel ball, and the first electrical connector 410 is a ring sleeve. The ring sleeve can be installed in the limiting cavity 310 of the rotating structural component 300, and through the downward open design of the limiting cavity 310, its lower surface can continuously maintain dynamic contact with the inner exposed copper 110 on the first PCB board 100.

[0057] Specifically, when the user rotates the knob 320, causing the rotating structural component 300 to rotate, the annular sleeve (first electrical connector 410) fixed in its limiting cavity 310 rotates synchronously, and its lower surface always slides / rotates on the inner exposed copper 110 to maintain electrical connection. At the same time, the steel ball (second electrical connector 430) in the limiting cavity 310, under the action of the spring 420, abuts against the concave teeth 220 of the toothed plate 200, and moves between the concave teeth as the rotating structural component 300 rotates, contacting different external exposed copper 120 in sequence to achieve gear switching.

[0058] Example 6

[0059] like Figure 7As shown, this embodiment further optimizes the rotating structural component 300 based on any one of embodiments one through five. Specifically, since there are many small parts in the elastic component, assembly is inconvenient, and there may be situations where any one of the small parts needs to be repaired or replaced. Therefore, this embodiment provides an opening in the rotating structural component 300 that connects to the limiting cavity 310, and a cover plate 330 is detachably installed at the opening. The cover plate 330 can be installed on the rotating structural component 300 through a snap-fit ​​structure, bolts, or other structures. Furthermore, the specific dimensions of the cover plate 330 are not limited in this embodiment and can be designed according to the specific structure of the elastic component. With this setting, when it is necessary to replace, install, or repair the elastic component, the cover plate 330 can be opened directly, making installation and disassembly convenient.

[0060] Example 7

[0061] like Figure 8 As shown, this embodiment further optimizes the gear shifting device based on any one of embodiments one through six. Specifically, the gear shifting structure in this embodiment also includes a second PCB board 500, which is mounted on the rotating structural component 300, with the inner exposed copper 110 mounted on the second PCB board 500. By adding the second PCB board 500, more or more complex electronic control functions, such as display and touch functions, can be incorporated into the gear shifting device. It should be noted that although some basic additional functions besides gear shifting can be achieved using the first PCB board 100 alone, for some higher-end / more complex functions, the optimal solution is to add the second PCB board 500 to implement them separately.

[0062] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
