Description

Technical Field

[0001] The utility model particularly relates to a large-size button structure of a steering wheel with good hand feeling. Background Art

[0002] With the development of technology, more and more accessories are added to cars, which can provide drivers with a comfortable driving environment. As the most direct expression between the driver and the vehicle, the steering wheel switch plays an important role in the vehicle. Especially during the entire driving process, if the driver expresses a certain intention or makes a certain driving action, compared with the switches in the central control or other areas, it is currently a more convenient and safer means of operation to issue a signal instruction through the switch on the steering wheel.

[0003] The buttons used in steering wheel switches are mostly direct-press and seesaw-type. The common seesaw-type structure is connected to the shaft in the middle and tilted to the left and right sides, but this tilting method swings a lot on both sides in actual use, and the tactile feedback is easy to be misunderstood, affecting the operation. Especially when using a large-size button structure, since the pressing position of the two is far away from the shaft position, it will shake, resulting in a poor feel. In order to solve the shaking problem, some manufacturers use a limiting method to guide and limit the buttons in all directions to reduce the setting of the rotating shaft. For example, Chinese patent CN 217306381 U discloses a car steering wheel switch, which is also arranged with a large-area four-way button on the upper surface of the shell, and four hooks are arranged on the lower end surface of the four-way button in four directions. Four hook columns are also arranged at corresponding positions of the shell to match the four hooks one by one, forming a non-rotating shaft four-way rocker button. However, due to the lack of an intermediate rotating shaft, the pressing feel is not as good as the rocker type with a rotating shaft, and when pressing in any direction, it will also partially drive the parts connected to it to move, so that the area division of the button is not very clear, and in order to avoid accidental touch, it is necessary to increase the stroke, which leads to the need for greater force to press, which makes the driver's operation feel poor.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0027] like Figures 1 to 7 As shown, the utility model discloses a large-size button structure for a steering wheel with a good hand feel, which includes a button and a mounting frame. The button can be swingably set on the mounting frame, with the axis of its swinging direction being the X direction, and the direction perpendicular to the direction being defined as the Y direction. The axis of the swinging direction hereinafter refers to the X direction, and the relatively matched buttons can be pressed up and down to realize the output of two functions.

[0028] The button 1 is swingably arranged on the mounting frame 2, and a first matching portion 11, an intermediate shaft matching portion 13 and a second matching portion 15 are sequentially arranged on the axis along the swinging direction thereof, and a first button portion 12 is arranged between the first matching portion 11 and the intermediate shaft matching portion 13, and a second button portion 14 is arranged between the second matching portion 15 and the intermediate shaft matching portion 13;

[0029] The mounting frame 2 has a first limiting portion 21 which is axially slidingly matched with the first matching portion 11, an intermediate shaft limiting portion 22 which is swingably matched with the intermediate shaft matching portion 13, and a second limiting portion 23 which is axially slidingly matched with the second matching portion 15, arranged in sequence on the axis along the swinging direction.

[0030] The intermediate shaft matching portion 13 includes a symmetrically arranged first waist-shaped hole 3, the lower end of the first waist-shaped hole 3 is arranged in an inclined surface, and the intermediate shaft limiting portion 22 includes two first rotating shafts 4 respectively matched with the first waist-shaped holes 3, and the lower end of the first rotating shaft 4 is adapted to the inclined surface of the first waist-shaped hole 3. Through the matching of the inclined surfaces, the pressing strokes of the two are consistent, the hand feel is improved, and the button resetting is convenient.

[0031] Both the first limiting portion 21 and the second limiting portion 23 are provided with a first protrusion 21 extending from the horizontal surface of the mounting frame toward the direction of the key, and a second rotating shaft 6 is provided on one side / both sides of the first protrusion 21. Both the first matching portion and the second matching portion are second protrusions 11a adapted to the first protrusion, and the second protrusion is provided with a second waist-shaped hole 5 that forms an axial sliding fit with the second rotating shaft 6. There are two second waist-shaped holes, which are symmetrically arranged to limit the first protrusion and facilitate limiting the second rotating shaft within the two second waist-shaped holes, which play a role in the X-direction limitation. At the same time, the length of the waist-shaped hole limits the key pressing stroke to avoid excessive pressing or excessive tilting.

[0032] Since the button 1 is in the shape of a long arc, the button will appear narrow at the upper end and wide at the lower end. Therefore, in order to ensure the reliability of the cooperation between the two, the first protrusion at the upper end of the mounting frame can be one, which is directly placed in the middle position of the button at the narrower end, and the first protrusion at the lower end can be two, which are set far apart, so as to cooperate with the second protrusions on both sides of the button at the wider end to achieve triangular stable fixation.

[0033] The first limiting portion 21 and the second limiting portion 23 are further provided with guide grooves 7, and the lower side of the key is correspondingly provided with guide ribs 8 adapted to the guide grooves. The guide ribs 8 cooperate with the guide grooves to achieve Y-direction limitation of the key and the mounting frame, thereby limiting the swing amount in the X and Y directions and reducing shaking.

[0034] The first limiting portion 21 can be directly provided with a guide groove on the first limiting portion, and since the two first protrusions of the second limiting portion are arranged far apart, a protrusion with a guide groove can be directly provided between the two first protrusions, and the protrusion and the first limiting portion 21 are on the same axis to ensure consistency of force without affecting its normal pressing action.

[0035] One end of the guide rib 8 is spherical 81 and extends to both sides. The spherical contact reduces the friction between the guide rib 8 and the guide groove, making the pressing smoother without jamming.

[0036] The intermediate shaft limiting part 22 is a groove-shaped structure integrally formed on the mounting frame, and the first rotating shaft 4 is integrally formed on the inner wall of the groove-shaped structure and symmetrically arranged. The intermediate shaft matching part 13 is two symmetrically arranged intermediate shaft vertical plates, and the intermediate shaft vertical plates are provided with first waist-shaped holes 3. The intermediate shaft vertical plates are inserted into the groove-shaped structure, and they can swing at a small angle relative to each other.

[0037] The mounting frame 2 is provided with a through slot 10 at positions corresponding to the first button portion 12 and the second button portion 14. The first button portion 12 and the second button portion 14 extend toward one side of the mounting frame to form a square slot 9. The projection area of ​​the square slot 9 is larger than the projection area of ​​the through slot 10. The two cooperate to accommodate the push switch, that is, the push switch can extend from the through slot to the upper surface of the mounting frame and be triggered by the button.

[0038] When the button 1 is matched with the mounting frame 2, the square groove 9 and the through groove 10 are partially staggered, which plays a role of dustproof and waterproof, and prevents dust or water from entering the interior through the matching gap between the two.

[0039] The embodiments should not be regarded as limiting the present invention, but any improvements based on the spirit of the present invention should be within the protection scope of the present invention.
