[0036] Combination Figure 1 to Figure 4The embodiment of the utility model provides an electronic shift button 2, which is applied to a transmission shifter. The electronic shift button 2 includes: a button base 24, which is provided with a mounting cavity; a button body 23, which is rotatably connected to the button base 24 and corresponds to one side of the mounting cavity; a first trigger component 25, which is arranged on the button body 23; a PCB board 28, which is arranged inside the mounting cavity; a second trigger component 27, which is arranged on the PCB board 28 and corresponds to the first trigger component 25; the second trigger component 27 includes a first button 271 and a rebound member 272, the rebound member 272 is arranged on the PCB board 28, the first button 271 is arranged on the rebound member 272, the first trigger component 25 corresponds to the first button 271, and when the button body 23 is pressed toward the button base 24, the first trigger component 25 elastically presses against the first button 271.

[0037] In this embodiment, the resilient member 272 may be a pot piece, which is specifically a sheet-like object with a protrusion on one side, and when the protrusion of the resilient member 272 is pressed, the resilient member 272 can be depressed downward, and when the resilient member 272 is released, it can automatically return to its original state; the first button 271 is arranged above the protrusion of the resilient member 272, and when the button body 23 is pressed, the button body 23 presses the first button 271 through the first trigger assembly 25, and the first button 271 presses the protrusion of the resilient member 272, so that the resilient member 272 is depressed downward and triggers the PCB board 28. When the first button 271 presses the resilient member 272, the elastic force of the resilient member 272 depressed downward provides the first button 271 with more hand feeling, so that the user can get a better hand feeling when pressing the electronic finger-shifting button 2.

[0038] In this embodiment, since the first trigger component 25 elastically presses against the first button 271 , when the button body 23 is released, the button body 23 is reset by the elastic force of the first trigger component 25 .

[0039] In one embodiment, the first trigger component 25 includes a first elastic member 251 and a second button 253 , one end of the first elastic member 251 is connected to the button body 23 , the second button 253 is disposed at the other end of the first elastic member 251 , and the second button 253 corresponds to the first button 271 .

[0040] In this embodiment, the first elastic member 251 corresponds to the first button 271. When the button body 23 is pressed, the second button 253 on the first elastic member 251 is pressed against the first button 271. At this time, after continuing to apply pressing force to the first elastic member 251, the first elastic member 251 is compressed toward the direction of the first button 271. When the first elastic member 251 is compressed to a certain extent, the elastic force gradually increases. Then, the elastic force of the first elastic member 251 is the same as the pressing force of pressing the button body 23. Continuing to press the button body 23 can make the second button 253 on the first elastic member 251 press the first button 271 of the second trigger component 27, and the first button 271 presses the rebound member 272. The rebound member 272 triggers the PCB board 28 to realize the speed shifting function.

[0041] Among them, the first elastic member 251 can be one of a spring, a compression spring, or a spring. In this embodiment, it is preferably a spring. By arranging the first elastic member 251 on the key body 23, an elastic force is exerted when the key body 23 is pressed, which can reduce the sensitivity of triggering the PCB board 28, avoid accidentally touching the key body 23 to trigger the PCB board 28, and improve the feel when pressing the key body 23.

[0042] In one embodiment, the first trigger assembly 25 further includes a second elastic member 252 , one end of the second elastic member 252 is connected to the button body 23 , and the other end of the second elastic member 252 corresponds to the button base 24 .

[0043] In this embodiment, by providing the second elastic member 252, when the key body 23 is pressed, the first elastic member 251 and the second elastic member 252 can jointly provide elastic force to the key body 23, thereby increasing the resistance of the key body 23 when pressed, and can further improve the feel of pressing the key body 23.

[0044] In this embodiment, the second elastic member 252 can be a spring, a compression spring, or a spring, and in this embodiment, it is preferably a spring; the second elastic member 252 can be arranged between the key body 23 and the key base 24, and in this embodiment, it is preferably arranged on the key body 23 and located on the outer periphery of the first elastic member 251, that is, the first elastic member 251 and the second elastic member 252 are coaxially arranged.

[0045] In one embodiment, the resilient member 272 includes a plurality of pot pieces, and the plurality of pot pieces are stacked and disposed on the PCB board 28 .

[0046] In this embodiment, multiple pot pieces can further improve the feel when pressing the key body 23, and two are preferred in this embodiment. Specifically, when the key body 23 is pressed, the key body 23 presses the first button 271 through the first trigger component 25, and the first button 271 presses two pot pieces at the same time, so that the two pot pieces are recessed toward the PCB board 28 and trigger the PCB board 28. Through such a setting, the two pot pieces improve the damping force of pressing the key body 23 to trigger the PCB board 28, thereby further improving the feel of pressing the key body 23.

[0047] In one embodiment, a limiting box 29 is disposed in the installation cavity, and a limiting groove 291 matching the shape of the PCB board 28 is formed on the limiting box 29 .

[0048] In this embodiment, the PCB board 28 is located in a limiting groove 291 of a matching shape, which is conducive to the stable installation of the PCB board 28, avoids the shaking of the PCB board 28, and ensures that the second trigger component 27 on the PCB board 28 will not be offset. When the key body 23 is pressed, it can ensure that the first trigger component 25 and the second trigger component 27 accurately correspond to each other, realize the linkage effect of the first trigger component 25 and the second trigger component 27, and improve the stability of the key body 23 triggering the PCB board 28.

[0049] In this embodiment, the PCB board 28 is set in a limit box 29, and the limit box 29 is installed in the key base 24. By disassembling the limit box 29 and then replacing it with another limit box 29 with other shapes inside, different types of PCB boards 28 can be easily adapted, thereby improving the application scenarios of the PCB board 28.

[0050] In one embodiment, the limiting box body 29 is provided with a waterproof cover 26 for sealing the notch of the limiting groove 291 , and the waterproof cover 26 is provided with an opening 261 for exposing the second trigger assembly 27 .

[0051] In this embodiment, the notch of the limit box 29 is closed by the waterproof cover 26, so as to prevent water vapor or dust from entering the limit groove 291 to affect the second trigger component 27, thereby improving the service life of the second trigger component 27. By opening the opening 261 on the waterproof cover 26, the second trigger component 27 can be exposed. When the first trigger component 25 corresponds to the second trigger component 27, when the button body 23 is pressed, the first trigger component 25 can press the exposed second trigger component 27 through the opening 261, thereby achieving the linkage effect of the first trigger component 25 and the second trigger component 27.

[0052] More specifically, the limit box 29 is provided with a wire outlet 292 , and the two wires of the PCB board 28 are passed through the wire outlet 292 and then filled with epoxy resin to ensure the sealing effect of the limit box 29 , thereby ensuring the waterproof effect of the limit box 29 .

[0053] In one embodiment, the second trigger component 27 further includes a waterproof soft glue 273 , and the waterproof soft glue 273 is wrapped around the first button 271 .

[0054] In this embodiment, the shape of the waterproof soft glue 273 is adapted to the shape of the first button 271 and wraps the first button 271. The second trigger component 27 is exposed to the opening 261 of the limit box 29 through the waterproof soft glue 273, thereby preventing water vapor from entering the limit box 29 from the opening 261 to affect the first button 271, the rebound part 272 and the PCB board 28, thereby improving the waterproof effect.

[0055] In this embodiment, the waterproof cover 26 can squeeze and assemble the waterproof soft glue 273 , the first button 271 , the resilient member 272 and the PCB board 28 in the limiting box 29 to ensure stable installation of the second trigger assembly 27 .

[0056] See also Figure 1 and Figure 2 As shown, the embodiment of the utility model further provides a transmission shifter, comprising a shifter base 1 and at least one electronic shift button 2 as described above, wherein one end of the electronic shift button 2 is provided with a pivot member 21 and is axially connected to the shifter base 1 through the pivot member 21, wherein the pivot member 21 can be set loosely or tightly, and the electronic shift button 2 can be rotated and adjusted relative to the shifter base 1 around the axis of the pivot member 21;

[0057] The electronic finger-shifting button 2 is provided with a positioning member 22 , and when the electronic finger-shifting button 2 is rotated and adjusted around the pivot member 21 , the positioning member 22 cooperates with the finger-shifting device base 1 to be positioned.

[0058] In the present embodiment, two electronic shift buttons 2 are provided, namely a downshift electronic shift button 2 and an upshift electronic shift button 2. To facilitate the adjustment of the rotation angle of the two electronic shift buttons 2, the pivot member 21 is set to be loose and tight. Specifically, the electronic shift button 2 can be operated to rotate around the pivot member 21 at one end only by loosening the pivot member 21, and the positioning member 22 is used to assist the electronic shift button 2 in rotating and positioning to the desired position. After rotating to the desired angle, the pivot member 21 is tightened to complete the rotation adjustment. The structure is simple and the adjustment is convenient.

[0059] See also Figure 2 and Figure 3As shown, in one embodiment, at least one mounting position 11 is provided on the finger shifter base 1, and a mounting hole 111 is provided in the mounting position 11, and the pivot member 21 passes through one end of the electronic finger shifting button 2 and the positioning member 22 and is threadedly connected to the corresponding mounting hole 111;

[0060] When the pivot member 21 is screwed into the corresponding mounting hole 111 , the electronic shift button 2 can be fixed with the corresponding mounting position 11 through the positioning member 22 ; when the pivot member 21 is loosened from the corresponding mounting hole 111 , the electronic shift button 2 can be rotated and adjusted and positioned with the corresponding mounting position 11 through the positioning member 22 .

[0061] In this embodiment, in order to facilitate the installation of the two electronic finger-shifting buttons 2, two corresponding installation positions 11 are provided. The installation holes 111 of the installation positions 11 can be threaded holes, and the pivot member 21 can be a half-thread screw, and the threads on the half-thread screw are located at the end of the half-thread screw; based on this, the end of the pivot member 21 passes through one end of the electronic finger-shifting button 2 and the positioning member 22 and is then threadedly connected to the installation hole 111, so that the threaded connection can be achieved. By operating the pivot member 21 to be screwed into the installation hole 111, the electronic finger-shifting button 2 and the positioning member 22 can be pressed against the installation position 11, and the electronic finger-shifting button 2 can be prevented from rotating loose by cooperating with the installation position 11 through the positioning member 22; by operating the pivot member 21 to be screwed out of the installation hole 111, the electronic finger-shifting button 2 and the positioning member 22 can be loosened relative to the installation position 11, so that the angle of the electronic finger-shifting button 2 can be rotatably adjusted.

[0062] Specifically, a positioning recess 112 is provided on the mounting position 11; a positioning protrusion 221 is provided on the side of the positioning member 22 that contacts the mounting position 11; the positioning recess 112 and the positioning protrusion 221 correspond to each other. It should be noted that a plurality of positioning recesses 112 can be provided, and they are circularly distributed on the circumferential outer side of the mounting hole 111; at least one positioning protrusion 221 can be provided, and the positioning protrusion 221 is positioned in the positioning recess 112. Based on this, when the pivot member 21 is tightened, the electronic finger shift button 2 is positioned with the mounting position 11 through the positioning member 22, and the positioning protrusion 221 of the positioning member 22 can correspond to the positioning recess 112 of the mounting position 11, which can prevent the electronic finger shift button 2 from loosening; and when the pivot member 21 is loose, the electronic finger shift button 2 can be rotated and adjusted and drive the positioning member 22 to rotate synchronously. During the rotation adjustment process, the positioning protrusion 221 on the positioning member 22 rotates relative to the positioning recess 112 of the mounting position 11, thereby generating an adjustment feedback sense, so that the user can perceive the angle of the rotation adjustment.

[0063] It should be understood that since the rotation adjustment is performed by the relative rotation of the positioning protrusion 221, the present embodiment may preferably provide the same number of positioning recesses 112 and positioning protrusions 221, that is, multiple positioning recesses 112 and multiple positioning protrusions 221 may be provided and all are distributed in a circular shape. By providing a one-to-one correspondence between multiple positioning recesses 112 and multiple positioning protrusions 221, the structural stability may be improved.

[0064] It should be understood that the number of positioning notches 112 may be further set to limit the angle of each rotation adjustment.

[0065] In one embodiment, the material of the finger shifter base 1 is metal, the material of the electronic finger shifter button 2 is plastic, and the position of the electronic finger shifter button 2 that contacts the finger shifter base 1 is coated with a metal layer.

[0066] In this embodiment, the finger shifter base 1 is set to be made of metal material, and the electronic finger shift button 2 is set to be made of plastic material. When the electronic finger shift button 2 is rotated and adjusted relative to the finger shifter base 1, the friction between the finger shifter base 1 and the electronic finger shift button 2 can be reduced, thereby improving the service life of the finger shifter base 1 and the electronic finger shift button 2; wherein, the metal material and the plastic material can be replaced with each other, and it is only necessary to ensure that one of the finger shifter base 1 and the electronic finger shift button 2 is made of metal material and the other is made of plastic material.

[0067] In this embodiment, the contact surface between the finger shifter base 1 and the electronic finger shift button 2 is coated with a metal layer, which enables the electronic finger shift button 2 to withstand a certain thrust, thereby increasing the service life of the electronic finger shift button 2.

[0068] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model.
