Description

Technical Field

[0001] This utility model relates to the field of vehicles, and more particularly to a column-type gear shift device and a vehicle equipped with the column-type gear shift device. Background Technology

[0002] Most modern vehicles are equipped with automatic transmissions, whose shift mechanisms include at least four gears: D (Drive), R (Reverse), N (Neutral), and P (Park). Drivers switch between D, R, and N by pushing the shift lever forward or backward. A shift mechanism mounted on the steering column is called a column-mounted shifter. Because it allows for greater design flexibility and improves the utilization of interior space, column-mounted shifters have become increasingly popular in recent years.

[0003] Existing column-mounted gear shifters generally do not have the function of shifting up or down gears. To achieve this function on a column-mounted gear shifter, separate paddle shifters are usually required, which increases costs and is not conducive to improving space utilization.

[0004] Therefore, there is a need for further improvement of the existing column-type gear shifting device.

[0005] The information disclosed in the background section of this utility model is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art.

Figure 4A As shown, a resilient snap-fit ​​322 is provided at the second end of the rotary drive member 320 (i.e., the end of the second extension 324). The resilient snap-fit ​​322 is installed into the mounting hole 344 to secure the knob 340 to the second end of the rotary drive member 320. Further, as... Figure 2B and Figure 2C As shown, the knob 340 includes a knob body 345 and a knob outer trim 346 fixed together. The knob body 345 is provided with the aforementioned mounting hole 344. A portion of the knob body 345 is located inside the shift lever 210, while the other portion of the knob body 345 and the knob outer trim 346 are located outside the shift lever 210.

[0098] Specifically, such as Figures 5A to 5D As shown, the bracket 230 includes a bracket body 232 and a support column 233 disposed inside the bracket body 232. A connecting portion 235 is provided inside the bracket body 232, and the support column 233 is connected to the connecting portion 235. The support column 233 extends along a second axis, and one end of the support column 233 protrudes from the bracket body 232 along the length of the mounting cavity 211 to form a knob mounting portion 236 (see attached diagram). Figure 5C and Figure 5D The knob 340 is mounted to the knob mounting portion 236 of the support column 233 and is able to rotate around the knob mounting portion 236 of the support column 233 (i.e., around the second axis).

[0099] A rotational space 234 exists between the support body 232 and the support column 233 to allow the rotary drive 320 to rotate about the second axis. Specifically, the second extension 324 of the rotary drive 320 passes through the rotational space 234 and is capable of rotating about the second axis within the rotational space 234.

[0100] Furthermore, such as Figure 5A As shown, the bracket 230 is provided with mounting holes 237, such as... Figure 6 As shown, a boss 224 is provided inside the mounting cavity 211. The boss 224 is engaged in the mounting hole 237 to install the bracket 230 inside the mounting cavity 211.

[0101] By following the first rotation direction (i.e., Figure 3A Rotating the knob 340 in the M1 direction causes the rotary drive 320 to rotate around the second axis along the first rotation direction, and under the cooperation of the first boss 321 and the arc-shaped slide groove 314, drives the first sliding member 310 to slide along the first direction (i.e., the negative direction of the y-axis), thereby causing the first trigger switch 313 of the first sliding member 310 to contact the first electrical connection contact 241.

[0102] When the first trigger switch 313 switches from being in contact with the second electrical connection contact 242 to being in contact with the first electrical connection contact 241, the first PCB board 240 can generate an upshift signal, which is used to increase the speed gear.

[0103] By following the second rotation direction (i.e., Figure 3A Rotating knob 340 (in the M2 direction) causes rotary drive member 320 to rotate around the second axis in the second rotation direction. Under the cooperation of the first boss 321 and the arc-shaped groove 314, it drives the first sliding member 310 to slide along the second direction (i.e., the positive y-axis direction), thereby causing the first trigger switch 313 of the first sliding member 310 to contact the third electrical connection contact 243. The second rotation direction is the opposite of the first rotation direction. The first direction (i.e., the negative y-axis direction) and the second direction (i.e., the positive y-axis direction) are two opposite directions extending along the second axis.

[0104] When the first trigger switch 313 switches from being in contact with the second electrical connection contact 242 to being in contact with the third electrical connection contact 243, the first PCB board 240 can generate a downshift signal, which is used to reduce the speed gear.

[0105] In one specific embodiment, the first rotation direction is clockwise when viewed from the knob 340 towards the rotary drive member 320, and the first direction is the direction in which the first sliding member 310 moves away from the bracket 230. The second rotation direction is counterclockwise when viewed from the knob 340 towards the rotary drive member 320, and the second direction is the direction in which the first sliding member 310 moves towards the bracket 230. In other embodiments, the first rotation direction can be counterclockwise when viewed from the knob 340 towards the rotary drive member 320, the first direction can be the direction in which the first sliding member 310 moves towards the bracket 230, the second rotation direction can be clockwise when viewed from the knob 340 towards the rotary drive member 320, and the second direction can be the direction in which the first sliding member 310 moves away from the bracket 230.

[0106] After generating an upshift or downshift signal, it is necessary to reset the knob 340 and the rotary drive 320. The following describes how to reset the knob 340 and the rotary drive 320.

[0107] In an exemplary implementation, such as Figure 2B and Figure 5D As shown, the shift lever assembly 200 further includes a first stop assembly 250, the first end of which is mounted to the side of the bracket 230 facing the knob 340. Figure 4BAs shown, a groove 349 is provided on the side of the knob 340 facing the bracket 230. The groove 349 is provided with a first inclined surface 341 and a second inclined surface 342. The first inclined surface 341 and the second inclined surface 342 intersect at the first connecting part 343.

[0108] The second end of the first abutting component 250 can slide relative to the knob 340 from abutting against the first inclined surface 341 or against the second inclined surface 342 to abutting against the first connecting portion 343, so as to push the knob 340 to rotate relative to the bracket 230, thereby causing the knob 340 to reset.

[0109] Specifically, during the process of generating the upshift signal (i.e., the process of the knob 340 rotating along the first rotation direction), the second end of the first abutment component 250 can slide relative to the knob 340 from the state of abutting against the first connection portion 343 to the state of abutting against the second inclined surface 342.

[0110] After the upshift signal is generated, the knob 340 is no longer rotated. The first abutment component 250 slides from its position abutting against the second inclined surface 342 relative to the knob 340 back to its position abutting against the first connecting portion 343, thereby pushing the knob 340 to rotate along the second rotation direction (i.e., reset). During this process, the rotary drive component 320 can follow the knob 340 to rotate around the second axis along the second rotation direction, and drive the first sliding component 310 to slide along the second direction (i.e., the positive y-axis direction) with the cooperation of the first boss 321 and the arc-shaped slide groove 314. When the first abutment component 250 slides back to its position abutting against the first connecting portion 343 relative to the knob 340, the first trigger switch 313 returns to the state of contact with the second electrical connection contact portion 242.

[0111] During the process of generating the downshift signal (i.e., the process of the knob 340 rotating along the second rotation direction), the second end of the first abutment component 250 can slide relative to the knob 340 from the state of abutting against the first connection portion 343 to the state of abutting against the first inclined surface 341.

[0112] After a downshift signal is generated, the knob 340 is no longer rotated. The first abutment component 250 slides from its position abutting against the first inclined surface 341 relative to the knob 340 back to its position abutting against the first connecting portion 343, thereby pushing the knob 340 to rotate along the first rotation direction (i.e., reset). During this process, the rotary drive component 320 can follow the knob 340 to rotate around the second axis along the first rotation direction, and drives the first sliding component 310 to slide along the first direction (i.e., the negative y-axis direction) with the cooperation of the first boss 321 and the arc-shaped slide groove 314. When the first abutment component 250 slides back to its position abutting against the first connecting portion 343 relative to the knob 340, the first trigger switch 313 returns to the state of contact with the second electrical connection contact portion 242.

[0113] In an exemplary implementation, such as Figure 5C and Figure 5D As shown, a first abutment assembly receiving cavity 231 with an opening facing the knob 340 is provided on one side of the bracket 230.

[0114] The first abutment assembly 250 includes a first telescopic head 251 and a first elastic member 252. The first telescopic head 251 is disposed within the first abutment assembly receiving cavity 231, and its head can extend out of the cavity. Both ends of the first elastic member 252 abut against the bottom wall of the first telescopic head 251 and the first abutment assembly receiving cavity 231, respectively, away from the first telescopic head 251, and are in a compressed state to support the first telescopic head 251.

[0115] The first elastic member 252, which is in a compressed state, can provide a first elastic force to the first telescopic head 251, so that the first telescopic head 251 can slide relative to the knob 340 from a state of abutting against the first inclined surface 341 or against the second inclined surface 342 to a state of abutting against the first connecting part 343.

[0116] In an exemplary embodiment, the position of the first inclined surface 341 away from the first connecting portion 343 is closer to the bracket 230 than the position of the first inclined surface 341 near the first connecting portion 343, so that the first abutting component 250 can slide relative to the knob 340 from a state of abutting against the first inclined surface 341 to a state of abutting against the first connecting portion 343 when the knob 340 is not subjected to external force.

[0117] The position of the second inclined surface 342 away from the first connecting portion 343 is closer to the bracket 230 than the position of the second inclined surface 342 near the first connecting portion 343, so that the first abutting component 250 can slide relative to the knob 340 from the state of abutting against the second inclined surface 342 to the state of abutting against the first connecting portion 343 when the knob 340 is not subjected to external force.

[0118] In an exemplary implementation, such as Figure 1 As shown, the column-type gear shift device further includes a button assembly 400, which is slidably mounted to the gear shift lever assembly 200, and a portion of the button assembly 400 can extend out from the gear shift lever assembly 200. By pressing the button assembly 400, the button assembly 400 slides relative to the gear shift lever assembly 200 along a first direction to achieve shifting to P gear.

[0119] The column shifter allows you to switch from N, R, and D to P.

[0120] In an exemplary implementation, such as Figure 3BAs shown, the first PCB board 240 is provided with a fourth electrical connection contact 244. For example... Figure 6 As shown, the mounting cavity 211 is provided with a mounting post 212 inside, the mounting post 212 is located on the second side of the first PCB board 240 and is provided with a sliding cavity 213.

[0121] like Figure 2B , Figure 2C and Figure 7 As shown, the button assembly 400 includes: a button 410, a second sliding member 420, a second trigger switch 430, and a push member 440.

[0122] The second sliding member 420 is mounted to the bracket 230 and can slide relative to the bracket 230 along the length direction of the mounting cavity 211 (i.e., the extension direction of the second axis). The first end of the second sliding member 420 is provided with an inclined pushing part 421 (see the attached diagram). Figure 7 and Figure 8A The second end of the second sliding member 420 passes through the bracket 230. Specifically, the second sliding member 420 is installed inside the support column 233 of the bracket 230.

[0123] Button 410 is mounted to the second end of the second sliding member 420. Second trigger switch 430 is located on the first side of the first PCB board 240. (As shown) Figure 8B As shown, the pushing member 440 includes a pressure plate 441, a second boss 442 located on the first side of the pressure plate 441, and a guide post 443 located on the second side of the pressure plate 441. The second boss 442 contacts the pushing part 421, the pressure plate 441 is located between the second trigger switch 430 and the pushing part 421, and the guide post 443 passes through the second trigger switch 430 and the first PCB board 240 and is slidably mounted to the sliding cavity 213 of the mounting post 212.

[0124] Pressing button 410 along the first direction causes the second sliding member 420 to slide along the first direction, and with the cooperation of the second boss 442 and the pushing part 421, the pushing member 440 and the second trigger switch 430 are driven to move towards the first PCB board 240, so that the second trigger switch 430 contacts the fourth electrical connection contact part 244 of the first PCB board 240.

[0125] The first PCB board 240 can generate a P-position signal when the second trigger switch 430 contacts the fourth electrical connection contact 244. The P-position signal is used to switch to the P-position.

[0126] Furthermore, such as Figure 6 As shown, limit grooves 223 are provided on both sides of the mounting post 212 in the radial direction. Figure 8BAs shown, the guide post 443 has limiting plates 444 on both sides in the radial direction, which correspond to the limiting groove 223. The limiting plates 444 are located in the limiting groove 223 to prevent the pushing member 440 from rotating around the axis of the guide post 443.

[0127] Furthermore, such as Figure 8C As shown, the second trigger switch 430 has a first through hole 432 corresponding to the guide post 443 and a first through groove 433 corresponding to the limiting plate 444 in its middle part, as shown. Figure 3B As shown, the first PCB board 240 is provided with a second through hole 245 corresponding to the guide post 443 and a second through groove 246 corresponding to the limiting plate 444.

[0128] The guide post 443 passes through the first through hole 432 of the second trigger switch 430 and the second through hole 245 of the first PCB board 240, and is slidably installed into the sliding cavity 213 of the mounting post 212. The limiting plate 444 passes through the first through slot 433 of the second trigger switch 430 and the second through slot 246 of the first PCB board 240, and is slidably installed into the limiting slot 223 of the mounting post 212.

[0129] Furthermore, such as Figure 8C As shown, the second trigger switch 430 is provided with a connection terminal 431. When the connection terminal 431 of the second trigger switch 430 contacts the fourth electrical connection contact 244 of the first PCB board 240, the first PCB board 240 can generate a P-position signal.

[0130] In an exemplary implementation, such as Figure 7 As shown, the button assembly 400 further includes a second elastic member 450, which is installed in the sliding cavity 213. Both ends of the second elastic member 450 abut against the guide post 443 and the bottom wall of the sliding cavity 213, respectively. The second elastic member 450 is in a compressed state and can provide a second elastic force to the pushing member 440. When the button 410 is not subjected to external force, the second elastic force can reset the pushing member 440 and the second trigger switch 430, and prevent the connection terminal 431 of the second trigger switch 430 from contacting the fourth electrical connection contact 244 of the first PCB board 240.

[0131] like Figure 2A As shown, the base 100 includes a base body 110 and a base cover 120 that are fastened together. The base 100 has an internal receiving space in which a mounting shaft 101 parallel to the steering column is installed, and the mounting shaft 101 extends along a first axis direction.

[0132] Specifically, both the base body 110 and the base cover plate 120 are provided with mounting shaft mounting parts 111, and the mounting shaft 101 is mounted on the mounting shaft mounting parts 111.

[0133] The second part 217 of the shift lever is provided with a mounting shaft connection 219, which is closer to the second end of the second part 217 than the first end of the shift lever. The second part 217 of the shift lever is mounted to the mounting shaft 101 via the mounting shaft connection 219, so that the shift lever assembly 200 can be rotatably mounted to the base 100 about the first axis.

[0134] In an exemplary implementation, such as Figure 2B As shown, the shift lever assembly 200 further includes a second stop assembly 260, the first end of which is mounted to the end of the shift lever 210 away from the knob assembly 300. Specifically, the first end of the second stop assembly 260 is mounted inside the first end of the second portion 217 of the shift lever.

[0135] like Figure 2A As shown, the column-type gear shift device further includes a gear shift seat 130, such as Figure 9 As shown, the shift seat 130 is located inside and fixed to the base 100, and is provided with a third inclined surface 131 and a fourth inclined surface 132 with opposite inclination directions. The third inclined surface 131 and the fourth inclined surface 132 intersect at the second connecting portion 133. The shift seat 130 is provided with a non-operating position Null located at the second connecting portion 133, a first operating position R and a second operating position Nr located on the third inclined surface 131, and a third operating position D and a fourth operating position Nd located on the fourth inclined surface 132. The second operating position Nr is closer to the non-operating position Null than the first operating position R, and the fourth operating position Nd is closer to the non-operating position Null than the third operating position D.

[0136] The second end of the second abutting component 260 can slide from abutting against the third inclined surface 131 or abutting against the fourth inclined surface 132 to abutting against the second connecting portion 133.

[0137] In an exemplary implementation, such as Figure 2B As shown, a second abutment assembly receiving cavity 218 is provided at one end of the shift lever 210 near the steering column. Specifically, the second abutment assembly receiving cavity 218 is located at the first end of the second part 217 of the shift lever.

[0138] The second abutment assembly 260 includes a second telescopic head 261 and a third elastic member 262. The second telescopic head 261 is disposed within the second abutment assembly receiving cavity 218, and its head can extend out of the cavity. The two ends of the third elastic member 262 abut against the bottom wall of the second telescopic head 261 and the second abutment assembly receiving cavity 218 away from the second telescopic head 261, respectively, and are in a compressed state to support the second telescopic head 261.

[0139] The third elastic member 262, which is in a compressed state, can provide a third elastic force to the second telescopic head 261, so that the second telescopic head 261 can slide from a state of abutting against the third inclined surface 131 or a state of abutting against the fourth inclined surface 132 to a state of abutting against the second connecting part 133.

[0140] In an exemplary embodiment, the position of the third inclined surface 131 away from the second connecting portion 133 is closer to the shift lever assembly 200 than the position of the third inclined surface 131 near the second connecting portion 133, so that the second abutment component 260 can slide from a state abutting against the third inclined surface 131 to a state abutting against the second connecting portion 133 when the shift lever assembly 200 is not subjected to external force. Specifically, when the shift lever assembly 200 is not subjected to external force, the second telescopic head 261 can slide from a state abutting against the first operating position R or a state abutting against the second operating position Nr back to a state abutting against the non-operating position Null.

[0141] The position of the fourth inclined surface 132 away from the second connecting portion 133 is closer to the shift lever assembly 200 than the position of the fourth inclined surface 132 near the second connecting portion 133, so that the second abutting component 260 can slide from a state abutting against the fourth inclined surface 132 to a state abutting against the second connecting portion 133 when the shift lever assembly 200 is not subjected to external force. Specifically, when the shift lever assembly 200 is not subjected to external force, the second telescopic head 261 can slide from a state abutting against the third operating position D or a state abutting against the fourth operating position Nd back to a state abutting against the non-operating position Null.

[0142] In an exemplary implementation, such as Figure 2B As shown, the shift lever assembly 200 further includes a magnetic component 201, which is fixed to the end of the shift lever 210 away from the rotary knob assembly 300 (i.e., the end near the steering column). Specifically, the magnetic component 201 is located at the first end of the second portion 217 of the shift lever. Figure 2A As shown, the column shifter further includes a second PCB board 140, which is installed inside the base 100 and is equipped with a sensor 141.

[0143] When the column shifter is in neutral (N) and the second stop assembly 260 is abutted in the non-operating position Null, the gear shifter moves along the third rotation direction (i.e., Figure 1The shift lever assembly 200 is pushed in the M3 direction, causing the magnetic component 201 to rotate relative to the sensor 141 in a third rotation direction. When the sensor 141 senses that the displacement of the magnetic component 201 in the third rotation direction reaches a first reference value, the second PCB board 140 generates a first trigger signal, which is used to switch from N gear to R gear.

[0144] During the shift from N to R gear, the second stop component 260 slides from the state of being stopped in the non-operating position Null to the state of being stopped in the first operating position R.

[0145] After shifting to reverse (R), the shift lever assembly 200 is no longer pushed, and the second stop assembly 260 slides from its position in the first operating position (R) back to its position in the non-operating position (Null). At this time, the column shifter remains in reverse (R).

[0146] In an exemplary embodiment, when the column shifter is in neutral (N) and the second abutment assembly 260 is abutted in the non-operating position Null, by moving along the fourth rotation direction (i.e., Figure 1 The shift lever assembly 200 is pushed in the M4 direction, causing the magnetic component 201 to rotate relative to the sensor 141 in the fourth rotation direction. When the sensor 141 senses that the displacement of the magnetic component 201 in the fourth rotation direction reaches the second reference value, the second PCB board 140 can generate a second trigger signal, which is used to switch from N gear to D gear.

[0147] During the shift from N to D gear, the second stop component 260 slides from the state of being stopped in the non-operating position Null to the state of being stopped in the third operating position D.

[0148] After shifting to D gear, the shift lever assembly 200 is no longer pushed, and the second stop assembly 260 slides from the state of being stopped in the third operating position D back to the state of being stopped in the non-operating position Null. At this time, the column shifter remains in D gear. The third and fourth rotation directions are opposite rotation directions.

[0149] exist Figure 1 In the implementation scheme, the third rotation direction is counterclockwise when viewed from the driver's seat, and the fourth rotation direction is clockwise when viewed from the driver's seat. That is, from... Figure 1 From the perspective of the third rotation direction, pushing the shift lever assembly 200 is pushing the shift lever assembly 200 upward, and pushing the shift lever assembly 200 is pushing the shift lever assembly 200 downward.

[0150] In an exemplary embodiment, when the column shifter is in reverse (R) and the second abutment assembly 260 is abutted in the non-operating position (Null), by moving along the fourth rotation direction (i.e., Figure 1 The shift lever assembly 200 is pushed in the M4 direction, causing the magnetic component 201 to rotate relative to the sensor 141 in the fourth rotation direction.

[0151] When the sensor 141 senses that the displacement of the magnetic component 201 along the fourth rotation direction reaches the third reference value, the second PCB board 140 can generate a third trigger signal. The third trigger signal is used to switch from R gear to N gear. The third reference value is less than the second reference value.

[0152] During the shift from R to N gear, the second stop component 260 slides from the state of being stopped in the non-operational position Null to the state of being stopped in the fourth operating position Nd.

[0153] After shifting to neutral (N), if the shift lever assembly 200 is no longer pushed, the second stop assembly 260 will slide from the state of being stopped in the fourth operating position Nd back to the state of being stopped in the non-operating position Null. At this time, the column shifter remains in neutral (N).

[0154] After shifting to N gear, if the shift lever assembly 200 is continued to be pushed along the fourth rotation direction, and when the sensor 141 senses that the displacement of the magnetic component 201 along the fourth rotation direction reaches the second reference value, the second PCB board 140 can generate a second trigger signal, thereby realizing the shift from N gear to D gear. During this process, the second stop component 260 will slide from the state of stopping at the fourth operating position Nd to the state of stopping at the third operating position D. After shifting to D gear, if the shift lever assembly 200 is no longer pushed, the second stop component 260 will slide from the state of stopping at the third operating position D back to the state of stopping at the non-operating position Null. At this time, the column shifter remains in D gear.

[0155] In an exemplary embodiment, when the column shifter is in D gear and the second abutment assembly 260 is abutted in the non-operating position Null, by moving along the third rotation direction (i.e., Figure 1 The shift lever assembly 200 is pushed in the M3 direction, causing the magnetic component 201 to rotate relative to the sensor 141 in the third rotation direction.

[0156] When the sensor 141 senses that the displacement of the magnetic component 201 along the third rotation direction reaches the fourth reference value, the second PCB board 140 can generate a fourth trigger signal. The fourth trigger signal is used to switch from D gear to N gear. The fourth reference value is less than the first reference value.

[0157] During the process of switching from D gear to N gear, the second stop component 260 slides from the state of being stopped in the non-operational position Null to the state of being stopped in the second operation position Nr.

[0158] After shifting to neutral (N), if the shift lever assembly 200 is no longer pushed, the second stop assembly 260 will slide from the state of being stopped at the second operating position (Nr) back to the state of being stopped at the non-operating position (Null). At this time, the column shifter remains in neutral (N).

[0159] After shifting to N gear, if the shift lever assembly 200 is continued to be pushed along the third rotation direction, and when the sensor 141 senses that the displacement of the magnetic component 201 along the third rotation direction reaches the first reference value, the second PCB board 140 can generate a first trigger signal, thereby realizing the shift from N gear to R gear. During this process, the second stop component 260 will slide from the state of abutting against the second operating position Nr to the state of abutting against the first operating position R. After shifting to R gear, if the shift lever assembly 200 is no longer pushed, the second stop component 260 will slide from the state of abutting against the first operating position R back to the state of abutting against the non-operating position Null. At this time, the column shifter remains in R gear.

[0160] In an exemplary embodiment, when the column shifter is in P gear and the second abutment assembly 260 is abutted in the non-operating position Null, by moving along the third rotation direction (i.e., Figure 1 The shift lever assembly 200 is pushed in the M3 direction, causing the magnetic component 201 to rotate relative to the sensor 141 in the third rotation direction.

[0161] When the sensor 141 senses that the displacement of the magnetic component 201 along the third rotation direction reaches the fourth reference value, the second PCB board 140 can generate a fifth trigger signal. The fifth trigger signal is used to switch from P gear to N gear. The fourth reference value is less than the first reference value.

[0162] During the process of switching from P gear to N gear, the second stop component 260 slides from the state of being stopped in the non-operational position Null to the state of being stopped in the second operation position Nr.

[0163] After shifting to neutral (N), if the shift lever assembly 200 is no longer pushed, the second stop assembly 260 will slide from the state of being stopped at the second operating position (Nr) back to the state of being stopped at the non-operating position (Null). At this time, the column shifter remains in neutral (N).

[0164] After shifting to N gear, if the shift lever assembly 200 is continued to be pushed along the third rotation direction, and when the sensor 141 senses that the displacement of the magnetic component 201 along the third rotation direction reaches the first reference value, the second PCB board 140 can generate a first trigger signal, thereby realizing the shift from N gear to R gear. During this process, the second stop component 260 will slide from the state of abutting the second operating position Nr to the state of abutting the first operating position R. After shifting to R gear, if the shift lever assembly 200 is no longer pushed, the second stop component 260 will slide from the state of abutting the first operating position R back to the state of abutting the non-operating position Null. At this time, the column shifter remains in R gear.

[0165] In an exemplary embodiment, when the column shifter is in P gear and the second abutment assembly 260 is abutted in the non-operating position Null, by moving along the fourth rotation direction (i.e., Figure 1 The shift lever assembly 200 is pushed in the M4 direction, causing the magnetic component 201 to rotate relative to the sensor 141 in the fourth rotation direction.

[0166] When the sensor 141 senses that the displacement of the magnetic component 201 along the fourth rotation direction reaches the third reference value, the second PCB board 140 can generate a sixth trigger signal, which is used to switch from P gear to N gear. The third reference value is less than the second reference value.

[0167] During the shift from P to N gear, the second stop component 260 slides from the state of being stopped in the non-operational position Null to the state of being stopped in the fourth operation position Nd.

[0168] After switching to N gear, if the shift lever assembly 200 is no longer pushed, the second stop assembly 260 will slide from the state of being stopped in the fourth operating position Nd back to the state of being stopped in the non-operating position Null. At this time, the column shift device remains in N gear.

[0169] After shifting to N gear, if the shift lever assembly 200 is continued to be pushed along the fourth rotation direction, and when the sensor 141 senses that the displacement of the magnetic component 201 along the fourth rotation direction reaches the second reference value, the second PCB board 140 can generate a second trigger signal, thereby realizing the shift from N gear to D gear. During this process, the second stop component 260 will slide from the state of stopping at the fourth operating position Nd to the state of stopping at the third operating position D. After shifting to D gear, if the shift lever assembly 200 is no longer pushed, the second stop component 260 will slide from the state of stopping at the third operating position D back to the state of stopping at the non-operating position Null. At this time, the column shifter remains in D gear.

[0170] This utility model embodiment also provides a vehicle equipped with the aforementioned column-type gear shift device. Other components and functions of the vehicle according to this utility model embodiment are known to those skilled in the art, and will not be described in detail to reduce redundancy.

[0171] The vehicle is equipped with an onboard computer. A first PCB board 240 is electrically connected to the onboard computer and sends upshift, downshift, and Park (P) gear signals to it. A second PCB board 140 is also electrically connected to the onboard computer and sends first, second, third, fourth, fifth, and sixth trigger signals to it. The onboard computer can switch gears based on these signals.

[0172] The operation of the column-type gear shifting device of this utility model will be described below with reference to the accompanying drawings.

[0173] When not subjected to external force, the column shifter is in a ready state. In the ready state, under the action of the second elastic force provided by the second elastic member 450, the second trigger switch 430 is not in contact with the fourth electrical connection contact 244 of the first PCB board 240.

[0174] like Figures 10A to 10C As shown, under the action of the first elastic force provided by the first elastic member 252 in a compressed state, the first telescopic head 251 abuts against the first connecting portion 343. The first trigger switch 313 contacts the second electrical connection contact portion 242 of the first PCB board 240.

[0175] Under the action of the third elastic force provided by the third elastic member 262 in a compressed state, the second telescopic head 261 abuts against the second connecting portion 133. That is, the second abutting component 260 abuts against the non-operating position Null.

[0176] At this time, the column shifter may be in P, N, D, or R gear.

[0177] Shifting to a higher gear:

[0178] When the column shifter is in D gear, it rotates along the first rotation direction (i.e., Figure 3A and Figure 10A Rotate knob 340 (in the M1 direction). Rotation drive 320 follows knob 340 to rotate around the second axis in the first rotation direction (see mating instructions). Figure 11A The first sliding member 310 is driven to slide along the first direction (i.e., the negative y-axis direction) in cooperation with the first boss 321 and the arc-shaped groove 314.

[0179] When the first trigger switch 313 switches from being in contact with the second electrical connection contact 242 to being in contact with the first electrical connection contact 241 (see also...) Figure 11B The first PCB board 240 generates an upshift signal and sends it to the vehicle's onboard computer. The onboard computer then adjusts the speed gear according to the upshift signal.

[0180] During the rotation of knob 340 along the first rotation direction, the second end of the first abutment assembly 250 can slide relative to knob 340 from a state of abutting against the first connecting portion 343 to a state of abutting against the second inclined surface 342 (i.e., Figure 10C state to Figure 11C (state).

[0181] After the upshift signal is generated, the user no longer rotates the knob 340. Since the position of the second inclined surface 342 away from the first connecting portion 343 is closer to the bracket 230 than the position of the second inclined surface 342 closer to the first connecting portion 343, the first abutting component 250 slides back from its position abutting against the second inclined surface 342 relative to the knob 340 to its position abutting against the first connecting portion 343 (i.e., Figure 11C state to Figure 10C The knob 340 is reset by rotating around the second axis in the second rotation direction. During this process, the rotary drive 320 follows the knob 340 in rotating around the second axis in the second rotation direction. With the cooperation of the first boss 321 and the arc-shaped slide groove 314, the rotary drive 320 drives the first sliding member 310 to slide along the second direction (i.e., the positive direction of the y-axis). When the first stop assembly 250 slides back to the state of abutting against the first connection part 343 relative to the knob 340, the first trigger switch 313 returns to the state of contacting the second electrical connection contact part 242 (i.e., returns to the state of contact). Figure 10B (state).

[0182] Downshifting to a lower gear:

[0183] When the column shifter is in D gear, by rotating along the second rotation direction (i.e., Figure 3A and Figure 10A Rotate knob 340 in the M2 direction. Rotation drive 320 follows knob 340 to rotate around the second axis in the second rotation direction (see mating instructions). Figure 12A The first sliding member 310 is driven to slide along the second direction (i.e., the positive y-axis direction) in cooperation with the first boss 321 and the arc-shaped groove 314.

[0184] When the first trigger switch 313 switches from being in contact with the second electrical connection contact 242 to being in contact with the third electrical connection contact 243 (see also...) Figure 12BThe first PCB board 240 can generate a downshift signal and send it to the vehicle's onboard computer. The onboard computer then reduces the speed gear based on the downshift signal.

[0185] During the rotation of knob 340 along the second rotation direction, the second end of the first abutment assembly 250 can slide relative to knob 340 from a state of abutting against the first connecting portion 343 to a state of abutting against the first inclined surface 341 (i.e., Figure 10C state to Figure 12C (state).

[0186] After the downshift signal is generated, the user stops turning the knob 340. Since the position of the first inclined surface 341 away from the first connecting portion 343 is closer to the bracket 230 than the position of the first inclined surface 341 near the first connecting portion 343, the first abutting component 250 slides back from its state of abutting against the first inclined surface 341 relative to the knob 340 to its state of abutting against the first connecting portion 343 (i.e., Figure 12C state to Figure 10C The knob 340 is reset by rotating around the second axis in the first rotation direction. During this process, the rotary drive 320 follows the knob 340 as it rotates around the second axis in the first rotation direction. With the cooperation of the first boss 321 and the arc-shaped slide groove 314, the rotary drive 320 drives the first sliding member 310 to slide along the first direction (i.e., the negative y-axis direction). When the first stop assembly 250 slides back to abut against the first connection portion 343 relative to the knob 340, the first trigger switch 313 returns to the state of contact with the second electrical connection contact portion 242 (i.e., returns to the state of contact with the second electrical connection contact portion 242). Figure 10B (state).

[0187] Shifting from N to R:

[0188] When the column shifter is in neutral (N) and the second stop assembly 260 is abutted in the non-operating position Null, the gear shifter moves along the third rotation direction (i.e., Figure 1 , Figure 13A and Figure 13B The shift lever assembly 200 is pushed in the M3 direction, causing the magnetic component 201 to rotate relative to the sensor 141 in the third rotation direction.

[0189] When sensor 141 detects that the displacement of magnetic component 201 along the third rotation direction reaches the first reference value, the second PCB board 140 generates a first trigger signal and sends it to the vehicle computer. The vehicle computer then switches from N to R gear based on the first trigger signal.

[0190] During the shift from N to R gear, the second abutment component 260 slides from its abutment in the non-operating position Null to its abutment in the first operating position R. Specifically, when the displacement of the magnetic component 201 along the third rotation direction reaches the first reference value, the second telescopic head 261 is precisely abutted in the first operating position R.

[0191] After shifting to R gear, the shift lever assembly 200 is no longer pushed. Since the position of the third inclined surface 131 furthest from the second connecting portion 133 is closer to the shift lever assembly 200 than the position of the third inclined surface 131 closest to the second connecting portion 133, under the action of the third elastic force provided by the third elastic member 262, the second telescopic head 261 of the second abutment assembly 260 slides from the state of abutting in the first operating position R back to the state of abutting in the non-operating position Null. That is, it returns to the ready state. At this time, the column shifter remains in R gear.

[0192] Shifting from N to D:

[0193] When the column shifter is in neutral (N) and the second stop assembly 260 is abutted in the non-operating position Null, the gear shifter moves along the fourth rotation direction (i.e., Figure 1 , Figure 14A and Figure 14B The shift lever assembly 200 is pushed in the M4 direction, causing the magnetic component 201 to rotate relative to the sensor 141 in the fourth rotation direction.

[0194] When sensor 141 detects that the displacement of magnetic component 201 along the fourth rotation direction reaches the second reference value, the second PCB board 140 generates a second trigger signal and sends it to the vehicle computer. The vehicle computer then switches from N to D gear based on the second trigger signal.

[0195] During the switching from N to D gear, the second stop component 260 slides from the non-operating position Null to the third operating position D. Specifically, when the displacement of the magnetic component 201 along the fourth rotation direction reaches the second reference value, the second telescopic head 261 is exactly abutted in the third operating position D.

[0196] After shifting to D gear, the shift lever assembly 200 is no longer pushed. Since the position of the fourth inclined surface 132 furthest from the second connecting portion 133 is closer to the shift lever assembly 200 than the position of the fourth inclined surface 132 closest to the second connecting portion 133, under the action of the third elastic force provided by the third elastic member 262, the second telescopic head 261 of the second abutment assembly 260 slides from the state of abutting in the third operating position D back to the state of abutting in the non-operating position Null. That is, it returns to the ready state. At this time, the column shifter remains in D gear.

[0197] Shifting from R to N:

[0198] When the column shifter is in reverse (R) and the second stop assembly 260 is abutted in the non-operating position (Null), the gear shifter moves along the fourth rotation direction (i.e., Figure 1 The shift lever assembly 200 is pushed in the M4 direction, causing the magnetic component 201 to rotate relative to the sensor 141 in the fourth rotation direction.

[0199] When sensor 141 detects that the displacement of magnetic component 201 along the fourth rotation direction reaches the third reference value, the second PCB board 140 generates a third trigger signal and sends it to the vehicle computer. The vehicle computer then switches from R to N gear based on the third trigger signal.

[0200] During the shift from R to N gear, the second telescopic head 261 of the second abutment assembly 260 slides from the non-operating position Null to the fourth operating position Nd. When the displacement of the magnetic component 201 along the fourth rotation direction reaches the third reference value, the second telescopic head 261 is precisely abutted at the fourth operating position Nd.

[0201] After shifting to N gear, you can either stop pushing the shift lever assembly 200 or continue pushing the shift lever assembly 200 in the fourth rotation direction.

[0202] If the shift lever assembly 200 is no longer pushed, the second telescopic head 261 of the second abutment assembly 260 will slide from the state of abutting in the fourth operating position Nd back to the state of abutting in the non-operating position Null, because the position of the fourth inclined surface 132 away from the second connecting part 133 is closer to the shift lever assembly 200 than the position of the fourth inclined surface 132 near the second connecting part 133. That is, it returns to the ready state. At this time, the column shift device remains in N gear.

[0203] If the shift lever assembly 200 is continued to be pushed along the fourth rotation direction, the magnetic component 201 can continue to rotate relative to the sensor 141 along the fourth rotation direction. When the sensor 141 senses that the displacement of the magnetic component 201 along the fourth rotation direction reaches the second reference value, the second PCB board 140 generates a second trigger signal and sends the second trigger signal to the vehicle computer. The vehicle computer switches from N gear to D gear according to the second trigger signal. During this process, the second telescopic head 261 of the second abutment assembly 260 slides from the state of abutting in the fourth operating position Nd to the state of abutting in the third operating position D. After switching to D gear, the shift lever assembly 200 is no longer pushed. Since the position of the fourth inclined surface 132 away from the second connecting part 133 is closer to the shift lever assembly 200 than the position of the fourth inclined surface 132 near the second connecting part 133, the second telescopic head 261 of the second abutment assembly 260 slides from the state of abutting in the third operating position D back to the state of abutting in the non-operating position Null. At this time, the column shifter remains in D gear.

[0204] Shifting from D to N:

[0205] When the column shifter is in D gear and the second stop assembly 260 is abutted in the non-operating position Null, by rotating along the third rotation direction (i.e., Figure 1 The shift lever assembly 200 is pushed in the M3 direction, causing the magnetic component 201 to rotate relative to the sensor 141 in the third rotation direction.

[0206] When sensor 141 detects that the displacement of magnetic component 201 along the third rotation direction reaches the fourth reference value, the second PCB board 140 generates a fourth trigger signal and sends it to the vehicle computer. The vehicle computer then switches from D to N gear based on the fourth trigger signal.

[0207] During the shift from D to N gear, the second telescopic head 261 of the second abutment assembly 260 slides from the state of abutting in the non-operating position Null to the state of abutting in the second operating position Nr. When the displacement generated by the magnetic component 201 along the third rotation direction reaches the fourth reference value, the second telescopic head 261 is exactly abutting in the second operating position Nr.

[0208] After shifting to N gear, you can either stop pushing the shift lever assembly 200 or continue pushing the shift lever assembly 200 in the third rotation direction.

[0209] If the shift lever assembly 200 is no longer pushed, the second telescopic head 261 of the second abutment assembly 260 will slide from the state of abutting in the second operating position Nr back to the state of abutting in the non-operating position Null, because the position of the third inclined surface 131 away from the second connecting part 133 is closer to the shift lever assembly 200 than the position of the third inclined surface 131 near the second connecting part 133. That is, it returns to the ready state. At this time, the column shifter remains in neutral (N).

[0210] If the shift lever assembly 200 is continued to be pushed along the third rotation direction, the magnetic component 201 can continue to rotate relative to the sensor 141 along the third rotation direction. When the sensor 141 senses that the displacement of the magnetic component 201 along the third rotation direction reaches the first reference value, the second PCB board 140 generates a first trigger signal and sends the first trigger signal to the vehicle computer. The vehicle computer realizes the shift from N gear to R gear according to the first trigger signal. During this process, the second telescopic head 261 of the second abutment assembly 260 slides from the state of abutting the second operating position Nr to the state of abutting the first operating position R. After shifting to R gear, the shift lever assembly 200 is no longer pushed. Since the position of the third inclined surface 131 away from the second connecting part 133 is closer to the shift lever assembly 200 than the position of the third inclined surface 131 near the second connecting part 133, the second telescopic head 261 of the second abutment assembly 260 slides from the state of abutting the first operating position R back to the state of abutting the non-operating position Null. At this time, the column shifter remains in R gear.

[0211] Shifting to P gear:

[0212] Regardless of whether the column shifter is in N, D, or R, it can be switched to P. Pressing button 410 along the first direction (i.e., the negative y-axis direction) causes the second sliding member 420 to slide along the first direction. During the sliding of the second sliding member 420 along the first direction, the pushing part 421 slides from its first contact position 422, which is in contact with the second boss 442, to its second contact position 423, which is in contact with the second boss 442 (see attached diagram). Figure 15A and Figure 15B ).

[0213] With the cooperation of the second boss 442 and the pusher 421, the pusher 440 and the second trigger switch 430 move toward the first PCB board 240 so that the connection terminal 431 of the second trigger switch 430 contacts the fourth electrical connection contact 244 of the first PCB board 240.

[0214] When the connection terminal 431 of the second trigger switch 430 contacts the fourth electrical connection contact 244, the first PCB board 240 generates a P-position signal and sends the P-position signal to the vehicle computer. The vehicle computer then switches to P-position according to the P-position signal.

[0215] As the pushing component 440 and the second trigger switch 430 move toward the direction of the first PCB board 240, the pushing component 440 further compresses the second elastic component 450.

[0216] After switching to P position, button 410 is no longer pressed. Under the action of the second elastic force provided by the compressed second elastic member 450, member 440 and the second trigger switch 430 are pushed away from the first PCB board 240 (i.e., reset), and the connection terminal 431 of the second trigger switch 430 is not in contact with the fourth electrical connection contact 244 of the first PCB board 240. With the cooperation of the second boss 442 and the pushing part 421, the pushing member 440 pushes the second sliding member 420 and the button 410 to slide along the second direction, thereby resetting the button 410.

[0217] Shifting from P to N:

[0218] When the column shifter is in P gear, the shift from P to N gear can be achieved in two ways.

[0219] The first method: When the column shifter is in P gear and the second stop assembly 260 is abutted in the non-operating position Null, by moving along the third rotation direction (i.e., Figure 1 The shift lever assembly 200 is pushed in the M3 direction, causing the magnetic component 201 to rotate relative to the sensor 141 in the third rotation direction.

[0220] When sensor 141 detects that the displacement of magnetic component 201 along the third rotation direction reaches the fourth reference value, the second PCB board 140 generates a fifth trigger signal and sends it to the vehicle computer. The vehicle computer then switches from P to N gear based on the fifth trigger signal. The fourth reference value is less than the first reference value.

[0221] During the shift from P to N gear, the second telescopic head 261 of the second abutment assembly 260 slides from the state of abutting in the non-operating position Null to the state of abutting in the second operating position Nr. When the displacement generated by the magnetic component 201 along the third rotation direction reaches the fourth reference value, the second telescopic head 261 is exactly abutting in the second operating position Nr.

[0222] After shifting to N gear, you can either stop pushing the shift lever assembly 200 or continue pushing the shift lever assembly 200 in the third rotation direction.

[0223] If the shift lever assembly 200 is no longer pushed, the second telescopic head 261 of the second abutment assembly 260 will slide from the state of abutting in the second operating position Nr back to the state of abutting in the non-operating position Null, because the position of the third inclined surface 131 away from the second connecting part 133 is closer to the shift lever assembly 200 than the position of the third inclined surface 131 near the second connecting part 133. That is, it returns to the ready state. At this time, the column shifter remains in neutral (N).

[0224] If the shift lever assembly 200 is continued to be pushed along the third rotation direction, the magnetic component 201 can continue to rotate relative to the sensor 141 along the third rotation direction. When the sensor 141 senses that the displacement of the magnetic component 201 along the third rotation direction reaches the first reference value, the second PCB board 140 generates a first trigger signal and sends the first trigger signal to the vehicle computer. The vehicle computer realizes the shift from N gear to R gear according to the first trigger signal. During this process, the second telescopic head 261 of the second abutment assembly 260 slides from the state of abutting the second operating position Nr to the state of abutting the first operating position R. After shifting to R gear, the shift lever assembly 200 is no longer pushed. Since the position of the third inclined surface 131 away from the second connecting part 133 is closer to the shift lever assembly 200 than the position of the third inclined surface 131 near the second connecting part 133, the second telescopic head 261 of the second abutment assembly 260 slides from the state of abutting the first operating position R back to the state of abutting the non-operating position Null. At this time, the column shifter remains in R gear.

[0225] The second method: When the column shifter is in P gear and the second stop assembly 260 is abutted in the non-operating position Null, by moving along the fourth rotation direction (i.e., Figure 1 The shift lever assembly 200 is pushed in the M4 direction, causing the magnetic component 201 to rotate relative to the sensor 141 in the fourth rotation direction.

[0226] When sensor 141 detects that the displacement of magnetic component 201 along the fourth rotation direction reaches the third reference value, the second PCB board 140 generates a sixth trigger signal and sends it to the vehicle computer. The vehicle computer then switches from P to N gear based on the sixth trigger signal. The fourth reference value is less than the first reference value.

[0227] During the shift from P to N gear, the second telescopic head 261 of the second abutment assembly 260 slides from the state of abutting in the non-operating position Null to the state of abutting in the fourth operating position Nd. When the displacement of the magnetic component 201 along the fourth rotation direction reaches the third reference value, the second telescopic head 261 is exactly abutting in the fourth operating position Nd.

[0228] After shifting to N gear, you can either stop pushing the shift lever assembly 200 or continue pushing the shift lever assembly 200 in the fourth rotation direction.

[0229] If the shift lever assembly 200 is no longer pushed, the second telescopic head 261 of the second abutment assembly 260 will slide from the state of abutting in the fourth operating position Nd back to the state of abutting in the non-operating position Null, because the position of the fourth inclined surface 132 away from the second connecting part 133 is closer to the shift lever assembly 200 than the position of the fourth inclined surface 132 near the second connecting part 133. That is, it returns to the ready state. At this time, the column shift device remains in N gear.

[0230] If the shift lever assembly 200 is continued to be pushed along the fourth rotation direction, the magnetic component 201 can continue to rotate relative to the sensor 141 along the fourth rotation direction. When the sensor 141 senses that the displacement of the magnetic component 201 along the fourth rotation direction reaches the second reference value, the second PCB board 140 generates a second trigger signal and sends the second trigger signal to the vehicle computer. The vehicle computer switches from N gear to D gear according to the second trigger signal. During this process, the second telescopic head 261 of the second stop assembly 260 slides from the state of stopping at the fourth operating position Nd to the state of stopping at the third operating position D. After switching to D gear, the shift lever assembly 200 is no longer pushed. Since the position of the fourth inclined surface 132 away from the second connecting part 133 is closer to the shift lever assembly 200 than the position of the fourth inclined surface 132 near the second connecting part 133, the second telescopic head 261 of the second stop assembly 260 slides from the state of stopping at the third operating position D back to the state of stopping at the non-operating position Null. At this time, the column shifter remains in D gear.
