Description

Technical Field

[0001] The present invention relates to the technical field of vehicle shifters, and in particular to an automatic lifting electric shifter. Background Art

[0002] As a shifting device of a vehicle, the shifter is an important part of the vehicle. It can be divided into a mechanical shifter and an electronic shifter. The mechanical shifter completes the switching between the gear combinations through a mechanical structure, and the electronic shifter issues an electronic signal through a control device, and the electronic signal controls an actuator to complete the switching between the gear combinations.

[0003] The mechanical shifting device has a complex structure and occupies a large space; moreover, the mechanical shifter is fixed and can only perform shifting by operating at angles in the front, rear, left, and right directions, but cannot perform lifting up and down. The shifter is mainly fixed at the position of the center console. Since it cannot be lifted, the integrity of the center console is affected, which affects the aesthetics.

[0004] Therefore, a liftable electric shifter has been developed. Before the vehicle is started, the shifter is in a hidden state, ensuring the integrity of the center console. After the vehicle is started, the shifter rises out, and after the vehicle is turned off, the shifter automatically descends and hides. It includes a shifting mechanism and a driving component for driving the lifting of the shifting mechanism. The driving component includes a motor and a lead screw. The shifting mechanism is in threaded cooperation with the lead screw. The motor drives the lead screw to rotate, so that the shifting mechanism slides on the lead screw to realize the lifting of the shifting mechanism. For the above-mentioned electric shifter, after it rises out, the shifter can be operated to realize gear shifting. However, for this lifting structure, due to the absence of a locking component, when the shifter is operated, the shifter is likely to retract, resulting in inconvenient subsequent shifting. Summary of the Invention

[0005] The object of the present invention: In order to overcome the defects of the prior art, the present invention provides an automatic lifting shifter, which is provided with a locking mechanism. After the shifting mechanism rises, it can be locked to prevent it from retracting during use.

[0006] The technical solution of the present invention is as follows: an automatic lifting electric shifter, comprising a bracket, a shift mechanism and a driving mechanism for driving the shift mechanism to rise and fall, and also comprising a locking mechanism for locking the shift mechanism after the shift mechanism rises, the driving mechanism comprising a cam, a swinging member and a driving member for driving the cam to rotate, the shift mechanism is provided with a fixed shaft, a rotating plate is rotatably provided on the fixed shaft, a connecting shaft is provided on the rotating plate, one end of the swinging member is hingedly arranged on the bracket through a hinge shaft, and the other end is hingedly arranged on the connecting shaft, the cam is rotatably arranged in the middle of the swinging member through a mounting shaft Below the position, a shell is provided in the bracket, the shift mechanism is slidably and lifted on the shell, the locking mechanism includes a lock tongue and a lock mouth provided on the shell for inserting the lock tongue, a slide groove is provided on the swinging member, the lock tongue is slidably provided in the slide groove, the cam is provided with an arc segment with the mounting axis as the center of the circle and a paddle that can drive the lock tongue to slide and be inserted into the lock mouth to realize locking of the shift mechanism, the paddle is set at the initial position of the arc segment, and the distance from any position on the arc segment to the center of the circle is equal, and a reset spring I for resetting the lock tongue away from the lock mouth is also provided in the slide groove.

[0007] By adopting the above technical solution, after the automobile is ignited and started, the driving member starts to work, drives the cam to rotate, and the cam drives the swinging member to move, thereby driving the shift mechanism to rise. After rising to the specified position, the cam continues to rotate. Because the cam is provided with an arc segment, when the cam rotates, it will no longer continue to drive the swinging member to move, and the swinging member is in a stationary state, and the paddle on the cam will drive the lock tongue to slide, push the lock tongue into the lock opening of the shell, lock the shift mechanism, and the motor stops rotating; in this way, when the user performs a shift operation on the shift mechanism, the shift mechanism will not be lowered, thereby not affecting the shift operation. When the flameout signal is received, the driving member rotates, drives the cam to rotate, and the lock tongue automatically escapes from the lock opening of the shell under the action of the reset spring I, and the shift mechanism is unlocked. The cam continues to rotate, drives the swinging member to move, drives the shift mechanism to descend, returns to the initial position, and the motor stops rotating; a locking mechanism is added, so that the shift mechanism can be locked after it rises, to prevent it from automatically descending when the shift mechanism is operated, thereby affecting the operation, making the shift mechanism safer, and driving the lifting and locking of the shift mechanism by a driving member can save costs.

[0008] Further configuration of the present invention: the shift mechanism includes a shift lever, a mounting seat, a circuit board and a movable seat slidably arranged in the mounting seat, the fixed shaft is arranged on the mounting seat, the circuit board is fixedly arranged in the mounting seat, and a plurality of Hall switches are arranged on the circuit board at intervals along the sliding direction of the shift lever, the shift lever is linked with the movable seat, the movable seat is slidably arranged above the circuit board, and a magnetic part is arranged on the movable seat corresponding to the position of the Hall switch.

[0009] With the above further arrangement, after the shift mechanism is unlocked, the lever is operated to make the lever slide on the bracket and drive the movable seat to slide, so that the Hall switch cooperates with the magnet to output a gear switching signal, and there is no contact between the magnet and the Hall switch, so no wear will occur and the service life is long. The use of the Hall switch makes the cost lower.

[0010] The present invention is further configured as follows: the shift mechanism also includes a track body, a roller and a sliding seat, the track body is fixedly arranged in the mounting seat, the sliding seat is slidably arranged in the movable seat, and one end extends outside the movable seat and is arranged opposite to the track body, the roller is arranged on the sliding seat, and can slide on the track body to realize gear switching, and a reset spring II for resetting the sliding seat is also provided in the movable seat.

[0011] By further adopting the above-mentioned configuration, the gear shifting operation is realized by sliding the roller on the track body, which can improve the operating feel. In addition, the original sliding friction is adjusted to rolling friction by the roller configuration, making the gear shifting operation smoother. The reset spring II resets the sliding seat after the gear shifting, so that the roller is always on the track body, and the structure is more stable. The roller is made of metal material, which is more wear-resistant and has a longer service life.

[0012] The present invention is further configured as follows: limit blocks are provided on both sides of the lock tongue, and a limit groove communicating with the slide groove is correspondingly provided on the swinging member, and the limit blocks are slidably arranged in the limit groove.

[0013] By adopting the above-mentioned further configuration, the sliding distance of the lock tongue can be limited to prevent it from leaving the slide groove, thereby facilitating the cooperation between the lock tongue and the cam to realize the locking of the shift mechanism.

[0014] The present invention is further configured as follows: the swing member includes a hinge portion, a mounting portion and two hinged arms, the hinge portion is hingedly arranged on the bracket through a hinge shaft, the slide groove is arranged on the mounting portion, two fixed shafts and two connecting shafts are correspondingly arranged, the two hinged arms are arranged on both sides of the slide groove, and one end extends into the outer shell to be connected with the corresponding connecting shaft, and the outer shell is correspondingly provided with notches for the two hinged arms to move.

[0015] By adopting the above-mentioned further arrangement, the shift mechanism has a more stable structure when being raised or lowered, and is not easily deflected, thereby ensuring the stability of the entire shifter.

[0016] The present invention is further configured as follows: two guide rods I are relatively arranged in the housing along its vertical direction, and the mounting seat is slidably arranged on the guide rods I.

[0017] The above further configuration plays a guiding role, so that the structure of the mounting seat is more stable when performing lifting movement.

[0018] A further improvement of the present invention: Two guiding rods II are relatively arranged horizontally inside the mounting base, and the movable seat is slidably arranged on the two guiding rods II.

[0019] With the above further improvement, it plays a guiding role, making the structure more stable when the movable seat slides horizontally. When the shifting lever performs a shifting operation, the stability is better, there will be no deviation, and the shifting operation can be better realized.

[0020] A further improvement of the present invention: A number of connecting blocks are provided on the shifting lever, and a number of connecting ports are correspondingly provided on the movable seat. Each connecting port is clamped in the corresponding connecting port to realize the connection between the shifting lever and the movable seat.

[0021] With the above further improvement, the structure is simple and the installation is convenient.

[0022] A further improvement of the present invention: The driving mechanism further includes a worm and a worm gear. The worm is arranged on the output shaft of the driving part and meshes with the worm gear. A gear I is integrally provided on the worm gear, and a gear II is provided on the cam. The gear II meshes with the gear I to drive the cam to rotate.

[0023] With the above further improvement, the driving part drives the cam to rotate through the cooperation of the worm gear and the gears. When the driving part stops working, the self-locking force of the worm itself is utilized to ensure that the shifting mechanism will not perform a shifting operation due to misoperation when the vehicle is in the flameout state, which is safer.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the protection scope of the present invention.

[0039] It should be noted that in the description of the present invention, all directional indications (such as up, down, front, back...) are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, then the directional indications will also change accordingly.

In the description of the present invention, "several" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0041] In addition, the technical solutions between various embodiments of the present invention can be combined with each other, but it must be based on the fact that those skilled in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0042] Such as Figure 1-14As shown in the figure, an automatic lifting electric shifter includes a bracket 1, a shifting mechanism 2, and a driving mechanism 3 for driving the lifting of the shifting mechanism 2. It also includes a locking mechanism 4 for locking the shifting mechanism 2 after it rises. The driving mechanism 3 includes a cam 31, a swinging member 33122, and a driving member 33 for driving the rotation of the cam 31. The driving member 33 is arranged as a motor. A fixed shaft 6 is provided on the shifting mechanism 2. A rotating plate 7 is rotatably provided on the fixed shaft 6. A connecting shaft 8 is provided on the rotating plate 7. One end of the swinging member 32 is hinged to the bracket 1 through a hinge shaft, and the other end is hinged to the connecting shaft 8. The cam 31 is rotatably provided below the middle position of the swinging member through a mounting shaft 30. A housing 5 is provided inside the bracket 1. The shifting mechanism 2 is slidably lifted on the housing 5. The locking mechanism 4 includes a locking tongue 41 and a locking opening 42 for the locking tongue to insert into. The locking opening 42 is provided on the housing 5. An arc segment 311 centered on the mounting shaft 30 and a dial 312 for driving the locking tongue to slide and insert into the locking opening to lock the shifting mechanism are provided on the cam 31. The dial 312 is provided at the initial position of the arc segment 311. The distance from any position on the arc segment 311 to the center of the circle is equal. A chute 321 is provided on the swinging member 32. The locking tongue 41 is slidably provided in the chute 321. A return spring I for resetting the locking tongue 41 in the direction away from the locking opening 42 is also provided in the chute 321. In order to facilitate the sliding of the locking tongue 41 driven by the dial 312 when the cam 31 rotates, a pressing block 411 is provided on the locking tongue 41. The dial 312 abuts against the pressing block 411 to drive the locking tongue 41 to slide and insert into the locking opening 42 to lock the shifting mechanism 2. After the vehicle is ignited and started, the driving member 33 starts to work, driving the cam 31 to rotate. The cam 31 drives the swinging member 32 to move, thereby driving the shifting mechanism 2 to rise. After rising to the specified position, the cam 31 continues to rotate. Since the arc segment 311 is provided on the cam 31, when the cam 31 rotates, it will no longer drive the swinging member 32 to move, and the swinging member is in a static state. However, the dial 312 on the cam 31 will abut against the pressing block 411, driving the locking tongue 41 to slide, and pushing the locking tongue 41 into the locking opening 42 of the housing 5 to lock the shifting mechanism 2. The motor stops rotating. In this way, when the user performs a shifting operation on the shifting mechanism 2, the shifting mechanism 2 will not descend, thus not affecting the shifting operation. When receiving the ignition-off signal, the driving member 33 rotates, driving the cam 31 to rotate. The dial 312 is separated from the pressing block 411 and no longer presses the pressing block 411. The locking tongue 41 automatically disengages from the locking opening 42 of the housing 5 under the action of the return spring I. The shifting mechanism 2 is unlocked. The cam 31 continues to rotate, driving the swinging member 32 to move, driving the shifting mechanism 2 to descend, and returning to the initial position. The motor stops rotating;A locking mechanism 4 is added, so that the shift mechanism 2 can be locked after it rises, to prevent it from automatically falling when the shift mechanism 2 is operated, thereby affecting the operation, making the shift mechanism 2 safer, and the shift mechanism 2 can be driven to rise and fall and lock by a driving member 33, which can save costs. ;

[0043] Specifically, limit blocks 412 are provided on both sides of the lock tongue 41, and a limit groove 322 communicating with the slide groove 321 is correspondingly provided on the swing member 32. The limit blocks 412 are slidably set in the limit groove 322, which can limit the sliding distance of the lock tongue 41 and prevent it from escaping from the slide groove, thereby facilitating the cooperation between the lock tongue 41 and the cam 31 to realize the locking of the shift mechanism 2.

[0044] In the present embodiment, the shift mechanism 2 comprises a lever 21, a mounting seat 22, a circuit board 23 and a movable seat 24 slidably arranged in the mounting seat 22, the fixed shaft 6 is arranged on the mounting seat 22, the circuit board 23 is fixedly arranged in the mounting seat 22, and a plurality of Hall switches 231 are arranged on the circuit board 23 at intervals along the sliding direction of the lever 21, the lever 21 cooperates with the movable seat 24, the movable seat 24 is slidably arranged above the circuit board 23, a magnetic member 241 is arranged on the movable seat 24 at a position corresponding to the Hall switch 231, and the magnetic member 241 is arranged by a magnet, after the shift mechanism 2 is unlocked, the lever 21 is operated to make the lever 21 slide on the bracket 1, and drive the movable seat 24 to slide, so that the Hall switch 231 cooperates with the magnet 241 to output a gear switching signal, and there is no contact between the magnet 241 and the Hall switch 231, no wear will occur, and the service life is long, and the use of the Hall switch 231 makes the cost low.

[0045] Specifically, the shift mechanism 2 also includes a track body 25, a roller 26 and a sliding seat 27. The track body 25 is fixedly arranged in the mounting seat 22, and the sliding seat 27 is slidably arranged in the movable seat 24, and one end extends to the outside of the movable seat 24 and is arranged opposite to the track body 25. The roller 26 is arranged on the sliding seat 27 and can slide on the track body 25 to achieve gear switching. A reset spring II242 for resetting the sliding seat 27 is also provided in the movable seat 24. The roller 26 slides on the track body 25 to achieve gear shifting, which can increase the operating feel. The roller 26 is arranged to adjust the original sliding friction to rolling friction, so that the gear shifting operation is smoother. The reset spring II242 resets the sliding seat 27 after the gear shift, so that the roller 26 is always on the track body 27, and the structure is more stable. The roller 26 is made of metal material, which is more wear-resistant and has a longer service life.

[0046] The swing member 32 includes a hinge portion 323, a mounting portion 324, and two hinge arms 325. The hinge portion 323 is hinged to the bracket 1 through a hinge shaft.

The housing 5 is correspondingly provided with notches 51 for the two hinge arms to move, so that the shifting mechanism 2 is more stable in structure during lifting, not easily offset, and the stability of the entire shifter is ensured.

[0047] In order to make the structure stable when the shifting mechanism is lifted and the movable seat slides horizontally, two guide rods I 52 are oppositely arranged in the housing 5 along its vertical direction. The mounting seat 22 is slidably arranged on the guide rods I 52, playing a guiding role, so that the mounting seat 22 is more stable in structure when making a lifting movement. Two guide rods II 221 are oppositely arranged in the mounting seat 22 along its horizontal direction. The movable seat 24 is slidably arranged on the two guide rods II 221, playing a guiding role, so that the movable seat 24 is more stable in structure when sliding horizontally. When the shift lever makes a shifting operation, the stability is better, there will be no offset, and the shifting operation can be better realized.

[0048] In this embodiment, a plurality of connecting blocks 211 are provided on the shift lever 21. A plurality of connecting ports 243 are correspondingly provided on the movable seat 24. Each connecting block 211 is clamped in the corresponding connecting port 243 to realize the connection between the shift lever 21 and the movable seat 24.

A gear II 313 is provided on the cam 31. The gear II 313 meshes with the gear I 351 to drive the cam 31 to rotate. The driving member 33 drives the cam 31 to rotate through the cooperation of the worm gear 35, the worm 34, and the gears. When the driving member 33 stops working, the self-locking force of the worm 34 itself is utilized to ensure that the shifting mechanism 2 will not perform a shifting operation due to misoperation when the vehicle is in the flameout state, which is safer.
