[0049] During driving, the driver realizes gear shifting through a gear shifter. There are three existing gear shifting modes in the field of existing automobiles, namely push rod type, knob type and button type. The electronic gear shifter of the push rod type has strong operating feeling, has low operating skill requirement for the driver, and can realize gear shifting in a blind manner during automobile driving, without the need to move the line of sight to the gear shifting mechanism, thereby ensuring the safety during driving. However, the gear shifter of the push rod type often occupies a large space in the driver's cabin, resulting in a narrow space in the driver's cabin. The gear shifters of the knob type and the button type can solve the problem of large space occupation of the traditional push rod type gear shifter, but the gear shifters of the knob type and the button type often need to move the line of sight to the gear shifting mechanism to confirm the gear position before operation, which causes the driver to not be able to always look at the front road, thereby reducing the safety factor during driving. Therefore, a gear shifter is needed which can integrate the advantages of small space occupation of the button type gear shifter and strong operating feeling and blind operation of the push rod type gear shifter.

[0050] In view of the problems existing in the prior art, the present application provides a button type gear shifter which can facilitate the driver to realize blind operation gear shifting in the driving process according to the different touch feeling and pressure feeling of each button. The driver does not need to look at the gear shifter to realize gear shifting, but can directly judge the gear position according to the touch feeling, thereby avoiding accidents caused by accidental touch and ensuring driving safety.

[0051] Reference Figures 1 to 10 , mainly reference Figures 1 to 3According to the key type gear shifting mechanism, the driver can easily blindly operate the keys 101 during driving, and the rate of mistaken touch is reduced.

[0052] According to the key type gear shifting mechanism, the driver can easily blindly operate the keys 101 during driving, and the rate of mistaken touch is reduced.

[0053] In the embodiment, the first direction is the left-right direction in the figure, the second direction is the up-down direction in the figure, and the third direction is the front-rear direction in the figure.

[0054] In some embodiments, the plurality of keys 101 includes a P gear key 110, an R gear key 120, an N gear key 130, and a D gear key 140 arranged at intervals along the first direction. The plurality of identification portions 102 includes a first groove 111, a second groove 121, a third groove 131, and a fourth groove 141, the first groove 111 is arranged on the upper surface of the P gear key 110, the second groove 121 is arranged on the upper surface of the R gear key 120, the third groove 131 is arranged on the upper surface of the N gear key 130, and the fourth groove 141 is arranged on the upper surface of the D gear key 140. The first groove 111 is different from the second groove 121, the second groove 121 is different from the third groove 131, the third groove 131 is different from the fourth groove 141, or the first groove 111, the second groove 121, the third groove 131, and the fourth groove 141 are all different. Figure 1 、 Figure 2In the embodiment, in the first direction, the arrangement order of the keys 101 from left to right is the P gear key 110, the R gear key 120, the N gear key 130, and the D gear key 140 in sequence. In order to distinguish the keys 101, the shapes of the P gear key 110 and the N gear key 130 are set as symmetrical patterns, the R gear key 120 is arranged between the P gear key 110 and the N gear key 130, and one end of the P gear key 110 and the N gear key 130 extends below the R gear key 120. The D gear key 140 is arranged on the side of the N gear key 130 away from the R gear key 120, and the D gear key 140 is set as a square. In addition to the above arrangement and shape, the P gear key 110, the R gear key 120, the N gear key 130, and the D gear key 140 can also be set as other shapes and arrangements, which can be selected according to actual needs.

[0055] In addition, in order to distinguish the touch of the keys 101, the upper surface of the R gear key 120 is provided with a second groove 121, the depth of the second groove 121 is deeper than the depth of the identification part 102 of the other keys 101, and the bottom surface of the second groove 121 is set as an inclined surface based on the horizontal plane. Specifically, when the finger of the driver contacts the R gear key 120, the side of the bottom surface of the second groove 121 close to the fingertip of the driver is lower, which conforms to the ergonomic principle and is more labor-saving when pressing the key 101, and is convenient for the driver to operate the gear shifting. The P gear key 110 is provided with a first groove 111, and the N gear key 130 is provided with a third groove 131. The first groove 111 is formed with a first arc surface, and the third groove 131 is formed with a second arc surface. When the finger of the driver contacts the P gear key 110 or the N gear key 130, the arc surface is in close contact with the finger of the driver. In addition, the curvature of the first arc surface is different from the curvature of the second arc surface. Specifically, the curvature of the first arc surface can be greater than the curvature of the second arc surface, or the curvature of the first arc surface can be smaller than the curvature of the second arc surface. At the same time, the depth of the first groove 111 and the depth of the third groove 131 are both smaller than the depth of the second groove 121. The upper surface of the D gear key 140 is provided with a fourth groove 141, the depth of the fourth groove 141 is greater than the depth of the first groove 111 and the second groove 121, and is smaller than the depth of the second groove 121. In addition, in order to distinguish the keys in the touch, the fourth groove 141 is formed with a third arc surface, and the curvature of the third arc surface is greater than the curvature of the first arc surface and the second arc surface. Through the above design, the driver can touch the keys 101 with hands during driving to distinguish different gears. When the driver is familiar with and remembers the touch of the keys 101 of each gear, the driver can perform blind operation gear shifting according to the touch during driving, enhance the operation feeling of the gear, reduce the rate of accidental touch, and further reduce the risk of accidents. At the same time, the gear shifting structure of the keys can save space, so that the interior space of the cockpit is larger and more spacious and comfortable.

[0056] Reference Figure 3In some embodiments, the sliding member 210, the elastic assembly 220 and the sliding plate assembly 230 are further included. One end of each sliding member 210 is connected with each key 101, and the sliding member 210 moves in a second direction perpendicular to the first direction when the key 101 is pressed. The elastic assembly 220 is provided with a plurality of elastic assemblies 220, each of which is arranged on both sides of the sliding member 210 in the first direction, and the elastic assembly 220 abuts against the sliding member 210 in a third direction perpendicular to both the first direction and the second direction. The other end of each sliding member 210 is connected with the sliding plate assembly 230, and the sliding member 210 drives the sliding plate assembly 230 to move in the first direction when the key 101 is pressed. Specifically, in order to ensure the stable pressing and rebounding of the key 101, the sliding member 210 is further arranged below each key 101, one end of the sliding member 210 is connected with the key 101, and the other end of the sliding member 210 extends above the circuit board 300, so that the sliding plate assembly 230 can contact the circuit board 300 and connect the circuit when the key 101 is pressed down. In order to stably hold the sliding member 210, the elastic assembly 220 is further arranged on both sides of the sliding member 210, and the elastic assembly 220 clamps the sliding member 210 in the third direction, so that the sliding member 210 can be stably clamped when moving in the second direction.

[0057] Further, referring to Figure 3 、 Figure 8 , the elastic assembly 220 includes a spring seat 221, a gear spring 222 and a contact 223, the gear spring 222 and the contact 223 are installed on the spring seat 221, the spring seat 221 is installed on the lower shell 200, one end of the contact 223 abuts against the sliding member 210, and the contacts 223 arranged on both sides of the sliding member 210 abut against and clamp the second sliding member 210 in the second direction. Referring to Figure 3 、 Figure 9The sliding piece assembly 230 includes a sliding piece support 231, a reset spring 232, a support seat 233, and a contact piece 234. The support seat 233 is fixedly installed on the lower shell 200, and the support seat 233 is connected with the sliding piece support 231 through the reset spring 232. The other end of the sliding piece 210 is connected with the sliding piece support 231. The sliding piece 210 and the sliding piece support 231 are connected in the following manner. The sliding piece 210 is provided with a connecting port 211, and the sliding piece support 231 is provided with a columnar guide rod 231a. The columnar guide rod 231a is inclined based on a horizontal plane, and the sliding piece support 231 is further provided with an inclined surface 231b which is substantially the same as the inclined direction of the columnar guide rod 231a. An inclined groove 231c is formed between the columnar guide rod 231a and the inclined surface 231b. A part of the connecting port 211 is sleeved in the inclined groove 231c. When the button is pressed downward, the connecting port 211 of the sliding piece 210 which is sleeved in the inclined groove 231c extrudes the inclined surface 231b of the sliding piece support 231, so that the sliding piece support 231 extrudes the reset spring 232 and is extruded into the support seat 233. When the button 101 is pressed, the support seat 233 is fixed, and the sliding piece support 231 can move along the first direction to the direction close to the support seat 233 under the pushing of the sliding piece 210, so that the contact piece 234 is in contact with the first conductive piece 301 and the second conductive piece 302 of the circuit board 300, and the circuit is connected, and the gear corresponding to the pressed button 101 is switched. When the button 101 is released, the sliding piece support 231 is pushed to return to the initial position under the elastic restoring force of the reset spring 232, so that the contact piece 234 is in contact with the first conductive piece 301 but not in contact with the second conductive piece 302 of the circuit board 300.

[0058] Referring to Figure 1 , Figure 4 In some embodiments, the two sides of the sliding piece 210 along the second direction are respectively provided with a first limiting part 212 and a second limiting part 213. When the button 101 is pressed, the elastic assembly 220 abuts against the first limiting part 212. When the button 101 is released (i.e. when the button is in a natural state), the elastic assembly 220 abuts against the second limiting part 213. Specifically, referring to Figure 4 , Figure 8The elastic assembly 220 includes a spring seat 221, a gear spring 222, and a contact 223. The gear spring 222 and the contact 223 are installed on the spring seat 221, and the spring seat 221 is installed on the lower shell 200. One end of the contact 223 abuts against the sliding piece 210, and the contacts 223 arranged on both sides of the sliding piece 210 abut against and hold the sliding piece 210 in the third direction. In order to ensure the holding effect of the elastic assembly 220 on the sliding piece 210 and a better pressing feeling, the sliding piece 210 is further provided with a first limiting portion 212 and a second limiting portion 213. The first limiting portion 212 and the second limiting portion 213 are two arc-shaped grooves with smooth transitions, and the depth of the arc-shaped groove of the second limiting portion 213 is greater than that of the arc-shaped groove of the first limiting portion 212. When the key 101 is pressed, the contact 223 of the elastic assembly 220 abuts against the first limiting portion 212, and when the key 101 is in a normal released state, the contact 223 abuts against the second limiting portion 213. In order to make the contact 223 abut against the first limiting portion 212 or the second limiting portion 213 more smoothly and facilitate the switching of the contact 223 between the first limiting portion 212 and the second limiting portion 213, the end of the contact 223 in contact with the first limiting portion 212 or the second limiting portion 213 is provided in a circular arc shape. When the key 101 is pressed, the sliding piece 210 moves downward, and at the same time, the sliding piece 210 extrudes the contact 223, so that the contact 223 moves to the inside of the spring seat 221, compresses the gear spring 222, and thus generates a rebound force, i.e., a key force. The structures of the first limiting portion 212 and the second limiting portion 213 can be adjusted according to actual needs, i.e., the depths or radii of the arc-shaped grooves of the first limiting portion 212 and the second limiting portion 213 or the spring force of the spring are adjusted to meet the key effect to be achieved.

[0059] In addition, in order to better distinguish the pressure feeling of each key 101, the arc-shaped grooves of the first limiting portion 212 and the second limiting portion 213 of the sliding piece 210 corresponding to each key 101 can be provided with different radii and / or depths, so that the driver gets different pressing feelings when pressing different keys 101.

[0060] Referring to Figure 3 , Figure 7In some embodiments, the circuit board 300 is further provided with a plurality of first conductive members 301 and a plurality of second conductive members 302, and the first conductive members 301 and the second conductive members 302 are alternately arranged. The slide assembly 230 is provided with a plurality of contact members 234. When the button is pressed, each contact member 234 is in contact with the first conductive member 301 and the second conductive member 302. When the button 101 is released, a part of the plurality of contact members 234 is in contact with the first conductive member 301. Specifically, the button-type gear shifting mechanism further comprises a circuit board 300, and the circuit board 300 is provided with a plurality of first conductive members 301 and a plurality of second conductive members 302 corresponding to the contact members 234. Referring to Figure 3 The first conductive members 301 are long gold fingers, and the second conductive members 302 are short gold fingers. In this embodiment, there are three long gold fingers and three short gold fingers, and the long gold fingers and the short gold fingers are alternately arranged.

[0061] The slide bracket 231 is provided with a sliding block, and the bracket seat 233 is provided with a sliding groove. The sliding block can slide in the sliding groove. The sliding member 210 is provided with a connecting port 211, and a part of the connecting port 211 is sleeved in the inclined groove 231c and in contact with the inclined surface 231b. When the button 101 is pressed, the sliding member 210 presses the slide bracket 231, and the slide bracket 231 slides to the inside of the bracket seat 233, thereby driving the contact member 234 below the slide bracket 231 to slide synchronously with the slide bracket 231. When the slide bracket 231 slides to the position, the contact member 234 is in contact with the short gold fingers and the long gold fingers on the circuit board 300 at the same time, thereby conducting the circuit. One long gold finger and one short gold finger form one circuit. In this embodiment, each button 101 is provided with three circuits, and the three circuits are connected in parallel. Any circuit can be normally connected. Of course, more circuits can be provided, such as four circuits, five circuits, and the like, to ensure that the button 101 has multiple guarantees, avoid the loss of electrical signals during use, and prevent accidents from occurring, thereby ensuring the safety during driving.

[0062] In some embodiments, the end of the sliding member 210 connected with the slide assembly 230 is provided with a buffer 214, which is in contact with the circuit board 300 when the button 101 is pressed. Specifically, in order to ensure good shock absorption and noise reduction, in the present embodiment, the sliding member 210 is further provided with a buffer 214, the upper end of which is in abutment with the lower housing 200 when the button 101 is in a normal released state, and the lower end of which is in contact with the circuit board 300 when the button 101 is in a pressed state, which can effectively play a shock absorption and noise reduction role when reaching the upper and lower limit surfaces. When the button 101 is pressed and reset, the buffer 214 can play a shock absorption and noise reduction role, and at the same time, can optimize the hand feeling and protect the circuit board 300. The buffer 214 can be made of soft materials such as rubber or silicone, in the present embodiment, the end of each sliding member 210 connected with the slide assembly 230 is provided with two I-shaped buffers 214, which are diagonally arranged on the sliding member 210, so that when the sliding member 210 moves downward, both I-shaped buffers 214 can be in contact with the circuit board 300, ensuring the stability of the button 101 pressing, avoiding the situation that the button 101 cannot be pressed to the position, resulting in poor contact or the button 101 is pressed too much, causing damage to the circuit board 300.

[0063] Referring to Figure 3 , Figure 5 and Figure 6In some embodiments, the upper shell 100, the lower shell 200 and the bottom plate 400 are further included. The upper shell 100 is provided with the first key groove 150, and each key 101 is accommodated in the first key groove 150. The lower shell 200 is formed with a plurality of cavities 201, each key 101 is accommodated in each cavity 201, and the inner wall of each cavity 201 is provided with an arc-shaped protrusion 202 abutting against the key 101. The circuit board 300 is arranged between the lower shell 200 and the bottom plate 400. Specifically, in order to ensure the overall stability of the key type gear shifting mechanism and ensure good key effect, the key type gear shifting mechanism further includes the upper shell 100, the lower shell 200 and the bottom plate 400, the upper shell 100 and the lower shell 200 form an accommodation cavity, and the sliding member 210, the elastic assembly 220 and the sliding sheet assembly 230 are installed in the accommodation cavity. In order to further ensure the stability of the key 101 during the pressing process, prevent the key 101 from shaking with the sliding member 210, the inner wall of each cavity 201 formed in the lower shell 200 is further provided with an arc-shaped protrusion 202. The arc-shaped protrusion 202 can be provided in multiple numbers, and the arc-shaped protrusion 202 abuts against the sliding member 210. On the one hand, the sliding member 210 can be stably retained by the arc-shaped protrusion 202, and on the other hand, the friction between the sliding member 210 and the lower shell 200 when the sliding member 210 moves in the second direction can be reduced. The overall stability of the device is improved, and at the same time, the pressing feeling is good.
