Description

Technical Field

[0001] This application relates to the field of vehicle transmission technology, specifically to an unlocking and noise-reducing shifting device and a vehicle. Background Technology

[0002] Currently, gear shifting devices typically include a lever and a shift rod. The shift rod is connected to an unlocking pin, and the lever has a guide groove to guide the movement of the unlocking pin. When the driver moves the shift rod, the unlocking pin slides along the guide groove, and the lever moves accordingly to shift gears. The problem is that the friction between the unlocking pin and the guide groove wall can generate a relatively loud noise, which can distract the driver. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes an unlocking noise-reducing gear shifting device that can effectively reduce the noise generated during gear shifting, thereby improving driver attention.

[0004] This application also proposes a vehicle having the aforementioned unlocking and noise-reducing shifting device.

[0005] The unlocking and noise-reducing shifting device according to an embodiment of this application includes a device body, a handle rod assembly, and a shift rod assembly;

[0006] The main body of the device is provided with a limiting groove that extends radially along the pivot.

[0007] The handle rod assembly is rotatably connected to the main body of the device around a pivot. The handle rod assembly is provided with a guide cavity and a guide groove. Both the guide cavity and the guide groove are arranged to extend radially along the pivot, and the guide groove and the guide cavity are connected along the axial direction of the pivot.

[0008] The shift lever assembly includes a shift lever, a cross pin, and a first buffer member. The shift lever passes through a guide cavity and is movably connected to a handle lever assembly. Along the axial direction of the pivot, the shift lever has a mounting hole, the cross pin passes through the mounting hole, and the cross pin extends into a guide groove.

[0009] The first buffer element surrounds the outer peripheral wall of the shift lever and abuts against the groove wall of the guide groove;

[0010] The unlocking and noise reduction shifting device has a parking state and a non-parking state. In the parking state, the horizontal pin is located in the limiting groove, and in the non-parking state, the horizontal pin is located outside the limiting groove.

[0011] The unlocking and noise-reducing gear shifting device according to the embodiments of this application has at least the following beneficial effects: The main body of the device is used to connect to the chassis of the vehicle body to fix the unlocking and noise-reducing gear shifting device. The guide cavity is used to guide the gear shift lever to move radially relative to the handle lever along the pivot. While the gear shift lever moves radially relative to the handle lever along the pivot, it can drive the cross pin to move in the guide groove, so that the cross pin enters or leaves the limiting groove, that is, to switch between the parking state and the non-parking state. In the parking state, the cross pin cooperates with the groove wall of the limiting groove to limit the rotation of the handle lever assembly relative to the main body of the device. In the non-parking state, the cross pin is located outside the limiting groove, and the handle lever assembly is driven to rotate relative to the main body of the device to achieve gear shifting. The first buffer member surrounds the outer peripheral wall of the cross pin and abuts against the groove wall of the guide groove. The first buffer member is used to block the relative friction between the cross pin and the groove wall of the guide groove, so that the friction between the cross pin and the groove wall of the guide groove is transformed into the friction between the first buffer member and the groove wall of the guide groove, which effectively reduces the noise of the unlocking and noise-reducing gear shifting device during gear shifting and helps to improve the driver's attention.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0046] The embodiments of this application are described below with reference to the accompanying drawings:

[0047] refer to Figures 1 to 6According to an embodiment of this application, an unlocking and noise-reducing gear shifting device is installed on a vehicle body for gear switching. The unlocking and noise-reducing gear shifting device has a parking state and a non-parking state. In the parking state, the vehicle is restricted from moving on its own, and in the non-parking state, the vehicle can move. The unlocking and noise-reducing gear shifting device includes a device body 100, a handle rod assembly 200, and a gear shifting rod assembly 300. The device body 100 is provided with a limiting groove 110 extending radially along a pivot 120. The handle rod assembly 200 is rotatably connected to the device body 100 around the pivot 120, and gear switching is achieved through the rotation between the handle rod assembly 200 and the device body 100. The handle rod assembly 200 is provided with a guide cavity 210 and a guide groove 220. Both the guide cavity 210 and the guide groove 220 extend radially along the pivot 120 and are connected to the guide cavity 210 along the axial direction of the pivot 120. The shift lever assembly 300 includes a shift lever 310, a cross pin 320, and a first buffer member 330. The shift lever 310 passes through the guide cavity 210 and is movably connected to the handle lever assembly 200. Along the axial direction of the pivot 120, the shift lever 310 is provided with a mounting hole 311, and the cross pin 320 passes through the mounting hole 311 and extends into the guide groove 220, so that the shift lever 310 and the cross pin 320 can move synchronously.

[0048] In the parking state, the horizontal pin 320 is located in the limiting groove 110. The horizontal pin 320 cooperates with the groove wall of the limiting groove 110 to restrict the rotation of the handle rod assembly 200 around the pivot 120 relative to the device body 100, so that the unlocking noise reduction shifting device is kept in the parking position. In the non-parking state, the horizontal pin 320 is located outside the limiting groove 110, and the handle rod assembly 200 can rotate around the pivot 120 relative to the device body 100 to switch gears.

[0049] The first buffer 330 is arranged around the outer peripheral wall of the cross pin 320 and abuts against the groove wall of the guide groove 220. The first buffer 330 can be made of plastic, rubber or other materials that can provide cushioning or deformation. By abutting against the groove wall of the guide groove 220, the first buffer 330 can provide guidance for the radial movement of the cross pin 320 along the pivot 120. Moreover, the first buffer 330 is used to block the friction between the cross pin 320 and the groove wall of the guide groove 220. Compared with the direct friction between the cross pin 320 and the groove wall of the guide groove 220, it is beneficial to reduce friction noise, making the gear shifting of the unlocking noise reduction shifting device quieter, which is beneficial to improving the driver's attention and making the vehicle driving safer.

[0050] It should be noted that, in order to ensure the structural stability of the unlocking noise reduction shifting device, the main body 100, the handle rod assembly 200, the shift lever 310, and the cross pin 320 are made of metal.

[0051] Specifically, refer to Figure 1The device body 100 has bolt holes at its bottom, which can be used to fix the device body 100 to the vehicle chassis. The device body 100 has gear slots 140 corresponding to different gear positions. Each gear slot 140 is distributed in an arc with the pivot 120 as the center. The handle rod assembly 200 has elastic protrusions 240. As the handle rod assembly 200 rotates relative to the device body 100 around the pivot 120, the elastic protrusions 240 can be engaged in the gear slots 140. Moreover, as the handle rod assembly 200 rotates at different angles, the elastic protrusions 240 can be engaged in different gear slots 140 to achieve gear switching.

[0052] refer to Figures 3 to 5 In some other embodiments, the mounting hole 311 may be a through hole that passes through the shift lever 310 along the axial direction of the pivot 120. The diameter of the mounting hole 311 is adapted to the shaft diameter of the cross pin 320. The cross pin 320 passes through the mounting hole 311 along the axial direction of the pivot 120, and the cross pin 320 is exposed at both opposite ends of the mounting hole 311. Correspondingly, the handle rod assembly 200 is provided with two guide grooves 220. Along the axial direction of the pivot 120, one guide groove 220 is located on one side of the mounting hole 311, and the other guide groove 220 is located on the opposite side of the mounting hole 311. The two ends of the cross pin 320 exposed outside the mounting hole 311 extend into the two guide grooves 220 respectively. At least one of the guide grooves 220 has a first buffer member 330 wrapped around the cross pin 320. The first buffer member 330 abuts against the groove wall of the guide groove 220, so that when the cross pin 320 moves with the shift lever 310, it only rubs against the groove wall of the guide groove 220 through the first buffer member 330, which helps to reduce friction noise during gear shifting.

[0053] refer to Figure 5 and Figure 6 In some embodiments, the unlocking noise reduction shifting device further includes a locking component 410, which is movably connected to the device body 100. The locking component 410 has a locked state and an unlocked state. The locking component 410 is used to communicate with the braking device to switch between the locked state and the unlocked state through the braking device. In the locked state, the locking component 410 is located on the side where the slot of the limiting groove 110 is located to restrict the horizontal pin 320 from leaving the limiting groove 110. In the unlocked state, the locking component 410 is located outside the movement trajectory of the horizontal pin 320 to avoid the horizontal pin 320. Therefore, when the unlocking noise reduction shift device is in the parking state and the braking device is not activated, the locking component 410 can restrict the movement of the cross pin 320, so that the unlocking noise reduction shift device remains in the parking state and avoids accidental gear shifting. When the braking device is activated, at least a part of the locking component 410 can move relative to the device body 100 to avoid the cross pin 320, so that the unlocking noise reduction shift device is released from the parking state, thereby improving the safety of vehicle parking.

[0054] Specifically, at least a portion of the locking assembly 410 is movably connected to the device body 100, and the connection method can be a sliding connection or a rotational connection, so that at least a portion of the locking assembly 410 can move relative to the device body 100. This portion is controlled by the braking device. When the braking device is activated, this portion exits the movement trajectory of the cross pin 320, allowing the unlocking noise reduction shifting device to switch gears. When the braking device is not activated, this portion is arranged on the movement trajectory of the cross pin 320 to restrict the cross pin 320 from disengaging from the limiting groove 110, thereby restricting the rotation of the handle rod assembly 200, that is, restricting the gear switching of the unlocking noise reduction shifting device, so that the vehicle can be parked stably and more safely.

[0055] It should be noted that the reference Figures 4 to 6 When the vehicle is parked, the guide groove 220 and the limiting groove 110 extend in the same direction, allowing the horizontal pin 320 to move simultaneously within the guide groove 220 and the limiting groove 110. Thus, when the locking assembly 410 is in the unlocked state, the horizontal pin 320 can disengage from the limiting groove 110, allowing the handle rod assembly 200 to rotate relative to the main body 100 of the device to switch the gear of the unlocking noise reduction shifting device.

[0056] refer to Figure 5 and Figure 6 In some embodiments, the locking assembly 410 includes a locking member 411 and a driving member 412. The locking member 411 is rotatably connected to the device body 100, and the driving member 412 is connected to the locking member 411. The locking member 411 is connected to the output end of the driving member 412. The driving member 412 is used for communication connection to the braking device so as to drive the locking member 411 to rotate and avoid the cross pin 320 when the braking device is activated. That is, when the braking device is activated, the locking assembly 410 is in the unlocked state, so that the unlocking noise reduction shifting device can perform gear switching. When the braking device is not activated, the locking member 411 is configured to be driven to reset by the driving member 412, and the locking assembly 410 switches to the locked state, restricting the unlocking noise reduction shifting device from switching between parking gear and non-parking gear.

[0057] Specifically, the structure of the locking member 411 can be adapted to the shape of the device body 100. The limiting groove 110 has a slot, and the locking member 411 is located on the side where the slot of the limiting groove 110 is located. The rotation center of the locking member 411 and the device body 100 is located on the side away from the limiting groove 110. The driving member 412 can be a linear motor, electromagnetic driver, or other structures. When the brake is applied, the output end of the driving member 412 generates an action to drive the locking member 411 to rotate relative to the device body 100, thereby avoiding the horizontal pin 320. The horizontal pin 320 can disengage from the limiting groove 110 through the slot of the limiting groove 110, thereby ensuring the rotation of the handle rod assembly 200 relative to the device body 100 for gear switching.

[0058] refer to Figures 4 to 6 In some embodiments, the unlocking and noise-reducing shifting device further includes a shifting locking structure 420, which is connected to the device body 100. The handle rod assembly 200 is provided with a locking part 230. The shifting locking structure 420 is communicatively connected to the locking assembly 410, and is used to connect to the braking device. The shifting locking structure 420 can be a mechanical linkage structure, an electromagnetic control structure, or other structures capable of locking and communication functions. If it is a mechanical linkage structure, force and movement can be transmitted through mechanical components such as levers and linkages; if it is an electromagnetic control structure, locking and unlocking actions are achieved through electromagnetic force. The shifting locking structure 420 establishes a communicative connection with the locking assembly 410, and is used to connect to the braking device.

[0059] In the parked state, the locking part 230 abuts against the shift locking structure 420 to make the locking component 410 connected to the braking device. Thus, when the braking device is activated, the locking component 410 can switch from the locked state to the unlocked state. Furthermore, the cross pin 320 can disengage from the limiting groove 110, allowing the lever assembly 200 to rotate relative to the device body 100 to achieve gear shifting. In the non-parked state, the locking part 230 separates from the shift locking structure 420 to disconnect the locking component 410 from the braking device. This ensures that when the unlocking and noise reduction shifting device is in the non-parked position, the connection between the braking device and the locking component 410 is disconnected, and the locking component 410 always remains in the locked state.

[0060] Therefore, in the parked state, the structural design in this embodiment helps ensure that when the driver presses the brake, the unlocking and noise-reducing shifting device can smoothly switch the locking component 410 from the parked state to the non-parked state, ensuring normal vehicle start-up and driving. Secondly, in the non-parked state, this structural design helps prevent the vehicle from accidentally shifting to park due to misoperation, thereby reducing the impact on the vehicle's transmission, lowering the risk of collision damage to internal vehicle components, extending the service life of the transmission, and improving the safety and stability of the vehicle during driving.

[0061] refer to Figure 7 and Figure 8In some embodiments, the unlocking noise reduction shifting device further includes an unlocking component 430, which includes an unlocking frame 431 and a first elastic element 432. The first elastic element 432 can be a spring, a rubber elastomer, or other component with elastic reset function. A spring achieves reset through its own deformation and restoring force, while a rubber elastomer relies on its own elastic deformation characteristics to complete the reset action. Along the radial direction of the pivot 120, one end of the first elastic element 432 is connected to the device body 100, and the other end of the first elastic element 432 abuts against the unlocking frame 431. The unlocking frame 431 is slidably connected to the device body 100. For example, a slide rail is provided on the device body 100, and a slider that cooperates with the slide rail is provided on the unlocking frame 431, or a groove and a sliding rod are used to allow the unlocking frame 431 to slide relative to the device body 100. The function of the first elastic element 432 is that when the unlocking frame 431 moves under external force, it can use its own elastic force to cause the unlocking frame 431 to reset.

[0062] The unlocking component 430 is configured to approach the locking component 410, apply a driving force to the locking component 410, and drive the locking component 410 to move relative to the main body 100, thereby switching the locking component 410 from a locked state to an unlocked state. When communication between the braking device and the locking component 410 fails, preventing unlocking of the locking component 410 through normal communication, the driver can manually drive the unlocking bracket 431. In this case, relying on the unlocking bracket 431 to drive the locking component 410, the unlocking operation of the locking component 410 can be completed.

[0063] refer to Figure 5 and Figure 6 In some embodiments, the unlocking noise reduction shifting device further includes a key detection module 440, which is connected to the device body 100. The key detection module 440 can be a detection structure based on a micro switch, pressure sensor, or electromagnetic induction principle. If it is a micro switch structure, the circuit is switched on and off by the contact and separation of the contacts; the pressure sensor outputs an electrical signal to control the circuit based on the magnitude of the applied pressure; the electromagnetic induction structure can use changes in the magnetic field to sense the position of the horizontal pin 320, thereby controlling the circuit state. The key detection module 440 is connected to the unlocking noise reduction shifting device body 100, and the connection method can be conventional methods such as bolt fixing or snap-fit ​​connection to ensure that the key detection module 440 is stably positioned on the unlocking noise reduction shifting device. In the locked state, the horizontal pin 320 abuts against the key detection module 440 to conduct the key detection circuit. For example, when the horizontal pin 320 presses against the micro switch, the switch contacts close to conduct the circuit. In the unlocked state, the horizontal pin 320 separates from the key detection module 440 to disconnect the key detection circuit.

[0064] Based on the above, when the vehicle is parked, the active key detection circuit facilitates starting the vehicle with the key, ensuring a smooth start-up process. When the vehicle is not parked, the disconnected key detection circuit prevents interference from the key signal to the vehicle control system during driving, reducing the risk of vehicle malfunctions due to key misoperation or signal abnormalities. Furthermore, this design allows the vehicle to be driven without a key, simplifying the driving process and allowing the driver to easily remove the key for other operations while the vehicle is in motion, thus improving the convenience and flexibility of vehicle use.

[0065] refer to Figure 5 and Figure 6 In some embodiments, the main body 100 of the device is further provided with a stop groove 130. The stop groove 130 can be rectangular, arc-shaped, or other shapes, depending on the movement trajectory and restriction requirements of the locking assembly 410. The locking assembly 410 also includes a second buffer 413. The locking assembly 410 includes an anti-rotation part 4111. The second buffer 413 is connected to the anti-rotation part 4111. Both the second buffer 413 and the anti-rotation part 4111 are located in the stop groove 130. The second buffer 413 can be a rubber buffer pad, a spring buffer, or other components with buffering and energy absorption functions. The stop groove 130 is used to restrict the movement space of the locking assembly 410. The position of the second buffer 413 should be set to ensure that it can abut against the groove wall of the stop groove 130 when the locking assembly 410 moves to its maximum position.

[0066] For example, the stop groove 130 can limit the rotation angle of the locking assembly 410. When the locking assembly 410 rotates during gear shifting, the anti-rotation part 4111 moves along with it. The groove wall of the stop groove 130 limits the range of motion of the anti-rotation part 4111, thereby ensuring that the locking assembly 410 can only rotate within a predetermined angle range. When the locking assembly 410 moves to its maximum position, the second buffer 413 abuts against the groove wall of the stop groove 130, mitigating the impact on the locking assembly 410 through its own buffering effect. This helps reduce the collision and wear between the locking assembly 410 and the device body 100, extends the service life of each component of the unlocking and noise-reducing gear shifting device, and also helps reduce the noise and vibration generated during gear shifting.

[0067] refer to Figure 5 and Figure 6In some embodiments, the unlocking noise-reducing shifting device further includes a third buffer 450, which may be a rubber buffer block, a sponge buffer, or a spring buffer structure, etc. The third buffer 450 is connected to the device body 100. The device body 100 is provided with multiple gear slots 140, each gear slot 140 being arranged in an arc around the pivot 120 as the center, used to define different gear positions of the unlocking noise-reducing shifting device. The handle rod assembly 200 includes an elastic protrusion 240, which at least partially has elastic deformation capability, allowing it to smoothly enter and exit each gear slot 140 during shifting operations. When the elastic protrusion 240 is located in any gear slot 140, the cross pin 320 abuts against the third buffer 450. At this time, the third buffer 450, through its own buffering characteristics, buffers and absorbs the force applied by the cross pin 320, which is beneficial to further reduce the noise and impact of the unlocking noise-reducing shifting device.

[0068] refer to Figure 3 and Figure 4 In some embodiments, the shift lever assembly 300 further includes a second elastic element 340. The second elastic element 340 may be a common elastic element such as a coil spring or a disc spring. The second elastic element 340 is located in the guide cavity 210 along the axial direction of the shift lever 310. One end of the second elastic element 340 abuts against the cavity wall of the guide cavity 210, and the other end of the second elastic element 340 abuts against the shift lever 310.

[0069] Specifically, during the gear shifting operation, when the gear shift lever 310 extends axially into the guide cavity 210, it further compresses the second elastic element 340, allowing the second elastic element 340 to store elastic potential energy. After the lever assembly 200 rotates to a certain extent to complete the gear shifting action, the second elastic element 340 rebounds using its stored elastic potential energy, pushing the gear shift lever 310 back to its original position. This reduces the driver's manual reset steps, simplifies the gear shifting process, and improves the convenience of gear shifting operations.

[0070] It should be noted that during assembly, the shift lever 310 is first inserted into the guide cavity 210. As the insertion process progresses, when the position of the mounting hole 311 on the shift lever 310 corresponds to the position of the guide groove 220, the cross pin 320 is inserted into the mounting hole 311 through the guide groove 220. This assembly method can effectively prevent the shift lever 310 from detaching from the guide cavity 210.
