[0038] In order to enable those skilled in the art to better understand the technical solution of the present invention, the combination switch handle of the present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] The present invention provides a combination switch handle, combined with Figure 1 , Figure 2 As shown, the combination switch handle includes a central axis 1, a first knob 2, and a second knob 3. The central axis 1 is installed inside the combination switch handle housing 5, and the central axis 1 remains fixed when in use. The first knob 2 and the second knob 3 each have a portion of the structure exposed outside the handle housing 5, and the exposed portion is for finger movement. The outer surfaces of the first knob 2 and the second knob 3 can be provided with a corrugated surface for increasing friction.

[0040] The first knob 2 and the second knob 3 are respectively arranged at the axial ends of the central axis 1. Figure 3 , Figure 4 , Figure 5 As shown, the axial direction of the central axis 1 is along the horizontal direction, the first knob 2 and the second knob 3 are arranged at intervals on the left and right, and the first knob 2 and the second knob 3 can rotate relative to the central axis 1. The rotation axis of the first knob 2 and the rotation axis of the second knob 3 can be parallel or overlapped with each other, or they can be non-parallel.

[0041] The central axis 1 is provided with a first corrugated surface 11 and a second corrugated surface 12, wherein the first corrugated surface 11 faces the first knob 2, and the second corrugated surface 12 faces the second knob 3; Figure 5 As shown, the first corrugated surface 11 and the second corrugated surface 12 are structures set on the central axis 1, wherein the first corrugated surface 11 and the second corrugated surface 12 are circular ring-shaped alternating concave and convex wave structures, the first corrugated surface 11 cooperates with the first knob 2, and the second corrugated surface 12 cooperates with the second knob 3.

[0042] The first knob 2 is installed with a first elastic component 21 that elastically expands and contracts along the direction of the rotation axis. The first elastic component 21 is installed on the first knob 2, the first elastic component 21 can rotate synchronously with the first knob 2, and the first elastic component 21 can elastically deform along the direction of the rotation axis of the first knob 2; the second knob 3 is installed with a second elastic component 31 that elastically expands and contracts along the direction of the rotation axis. The second elastic component 31 is installed on the second knob 3, the second elastic component 31 can rotate synchronously with the second knob 3, and the second elastic component 31 can elastically deform along the direction of the rotation axis of the second knob 3.

[0043] When the first knob 2 and the second knob 3 are assembled on the central axis 1, the first elastic component 21 can press against the first corrugated surface 11 to form a rotation feel, and the second elastic component 31 can press against the second corrugated surface 12 to form a rotation feel. When the first knob 2 or the second knob 3 rotates, the first elastic component 21 and the second elastic component 31 will be driven to rotate, and the undulating corrugated blocks of the first corrugated surface 11 will alternately contact and periodically squeeze the first elastic component 21, and the undulating corrugated blocks of the second corrugated surface 12 will alternately contact and periodically squeeze the second elastic component 31. When the first elastic component 21 or the second elastic component 31 contacts the raised part, it is compressed, and when the first elastic component 21 or the second elastic component 31 contacts the recessed part, it rebounds, forming a "click" vibration feel during the rotation process.

[0044] In the present invention, the first knob 2 and the first corrugated surface 11 provided on the central shaft 1 cooperate to form a rotation feel, and the second knob 3 and the second corrugated surface 12 provided on the central shaft 1 cooperate to form a rotation feel. It is only necessary to provide the first elastic component 21 between the first knob 2 and the central shaft 1, and the second elastic component 31 between the second knob 3 and the central shaft 1, and it is not necessary to provide additional curved surface blocks for the first knob 2 and the second knob 3. The first corrugated surface 11 and the second corrugated surface 12 are integrated into the central shaft 1 in one piece, and it is not necessary to provide a curved surface block for each knob separately, so the assembly is more convenient.

[0045] The central axis 1 of the present invention is provided with a first rotary axis 13 and a second rotary axis 14, Figure 3 , Figure 5 As shown, the first corrugated surface 11 and the second corrugated surface 12 are respectively arranged on the left and right end surfaces of the central shaft 1, the first rotary shaft 13 is protrudingly arranged on the left end surface of the central shaft 1, and the second rotary shaft 14 is protrudingly arranged on the right end surface of the central shaft 1. The cross section of the first rotary shaft 13 and the cross section of the second rotary shaft 14 are circular, and the radial dimension of the first rotary shaft 13 and the radial dimension of the second rotary shaft 14 are both smaller than the radial dimension of the central shaft 1, and a size mutation is formed at the junction of the first rotary shaft 13 and the central shaft 1, and a size mutation is formed at the junction of the second rotary shaft 14 and the central shaft 1.

[0046] The first knob 2 and the second knob 3 are respectively provided with installation channels, the first knob 2 is rotatably mounted on the first rotating shaft 13, the first knob 2 and the first rotating shaft 13 are rotationally matched, and the first knob 2 rotates around the first rotating shaft 13. The second knob 3 is rotatably mounted on the second rotating shaft 14, the second knob 3 and the second rotating shaft 14 are rotationally matched, and the second knob 3 rotates around the second rotating shaft 14.

[0047] Combination Figure 3 , Figure 5As shown, the first elastic component 21 includes a first spring 211 and a first ball 212. One end of the first spring 211 is pressed on the first knob 2, and the other end of the first spring 211 contacts the first ball 212. The first spring 211 presses the first ball 212 against the surface of the first corrugated surface 11. Since the first elastic component 21 cannot rotate with the first knob 2, the first ball 212 and the first corrugated surface 11 are relatively displaced. The concave and convex blocks of the first corrugated surface 11 alternately contact and squeeze the first ball 212, so that the first spring 211 is compressed.

[0048] The second elastic component 31 includes a second spring 311 and a second ball 312. One end of the second spring 311 is pressed on the second knob 3, and the other end of the second spring 311 contacts the second ball 312. The second spring 311 presses the second ball 312 against the second corrugated surface 12. The second elastic component 31 cannot rotate with the second knob 3. Therefore, the second ball 312 and the second corrugated surface 12 are relatively displaced. The concave and convex blocks of the second corrugated surface 12 alternately contact and squeeze the second ball 312, so that the second spring 311 is compressed.

[0049] In addition to the spring-ball structure, the first elastic component 21 and the second elastic component 31 may also adopt a metal spring structure, and these structures should also be included in the protection scope of the present invention.

[0050] Combination Figure 3 As shown, the first knob 2 is provided with two first receiving grooves 22, the inner cavity of the first receiving groove 22 is cylindrical, the two first receiving grooves 22 are used to insert two first springs 211, and each first receiving groove 22 is correspondingly installed with a first spring 211 and a first ball 212. The second knob 3 is provided with two second receiving grooves 32, the two second receiving grooves 32 are used to insert two second springs 311, and each second receiving groove 32 is correspondingly installed with a second spring 311 and a second ball 312. Figure 6 Shown, there is a schematic diagram of the structure of the second knob 3, and the first knob 2 is similar to this structure.

[0051] The first knob 2 is provided with two or more first elastic components 21, so that the first knob 2 is subjected to uniform elastic force, and the elastic force exerted on the first knob 2 is parallel to the rotation axis direction of the first knob 2. Similarly, the second knob 3 is provided with two or more second elastic components 31, so that the elastic force exerted on the second knob 3 is parallel to the rotation axis direction of the second knob 3. The elastic forces exerted on the first knob 2 and the second knob 3 are parallel to their respective rotation axes, which can prevent the first knob 2 and the second knob 3 from tilting.

[0052] The first knob 2 and the second knob 3 adopt similar structural designs. The first knob 2 and the second knob 3 can rotate independently relative to the central axis 1, and function switching is achieved by rotating the first knob 2 and the second knob 3 respectively.

[0053] Specifically, the corrugation size of the first corrugated surface 11 and the corrugation size of the second corrugated surface 12 in the present invention are different, that is, the height and circumferential length of the concave and convex are different, and the size of the rotation amplitude is determined according to the function to be achieved by each knob to form a different rotation feel. In addition, the elastic force of the first elastic component 21 and the second elastic component 31 is also different. Through these differences, the difference in the rotation feel of the two knobs is achieved, for example, the force required for twisting is different, or the amplitude of a single twist is different, providing tactile feedback to the user to distinguish the two knobs.

[0054] Based on any of the above technical solutions and their combinations, the present invention sets a gold-plated soft board 15 on the central axis 1, the gold-plated soft board 15 is provided with contacts for triggering signals, and the gold-plated soft board 15 is connected to the controller through a wire.

[0055] A first gold finger 23 is installed on the first knob 2. When the first gold finger 23 rotates with the first knob 2, it can cooperate with different contacts of the gold-plated soft board 15 to conduct signals, thereby realizing function switching. A second gold finger 33 is installed on the second knob 3. When the second gold finger 33 rotates with the second knob 3, it can cooperate with different contacts of the gold-plated soft board 15 to conduct signals, thereby realizing function switching.

[0056] Specifically, stop blocks can be respectively provided on the first knob 2 and the second knob 3, which are not shown in the drawings. The stop blocks are used to cooperate with the blocking structure on the central axis 1 to limit the rotation limit of the first knob 2 and the second knob 3. The rotation range of the first knob 2 and the second knob 3 is limited by this limiting structure.

[0057] Combination Figure 3 As shown, the first elastic component 21 and the first gold finger 23 are located on the same side of the first knob 2, and are both arranged on the side of the first knob 2 close to the central axis 1. The second elastic component 31 and the second gold finger 33 are located on the same side of the second knob 3, and are both arranged on the side of the second knob 3 close to the central axis 1.

[0058] Combination Figure 1 , Figure 3As shown, the combination switch handle of the present invention further includes a button 4, which is arranged at the end of the handle housing 5 and is used for being pressed to realize function triggering. In the present invention, the first knob 2 and the second knob 3 can rotate relative to the handle housing 5, and the button 4 can be pressed and moved relative to the handle housing 5. The first knob 2, the second knob 3, and the button 4 can respectively realize respective signal triggering, thereby realizing the switching of related functions. For example, the button 4 realizes the front wiper inching and the front wiper spraying functions, the first knob 2 realizes the switching of the wiper off, the wiper with low sensitivity, the wiper with high sensitivity, the low-speed wiper, and the high-speed wiper, and the second knob 3 realizes the switching of the rear wiper off, the rear wiper spraying, and the rear wiper on.

[0059] Combination Figure 2 As shown, the first knob 2 of the present invention protrudes and is exposed on the upper surface and the lower surface of the handle housing 5; the second knob 3 protrudes and is exposed on the upper surface and the lower surface of the handle housing 5. When operating to turn the first knob 2 or the second knob 3, it can be turned from the exposed part at the top or from the exposed part at the bottom, respectively.

[0060] Compared with the existing structure, the present invention integrates the first knob 2 and the second knob 3 into the handle housing 5, and directly processes the first corrugated surface 11 and the second corrugated surface 12 for realizing the operating force feel on the central axis 1, so that the operating force feel can be realized without designing and processing the curved surface block parts separately. The cost of the two curved surface blocks is saved, the installation space of the two curved surface blocks is saved, and the assembly efficiency is improved.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
