Description

Technical Field

[0001] The present invention relates to the technical field of vehicle engineering, and in particular to a dual-mode gear shifter. Background Art

[0002] A Chinese invention patent application numbered 202110559605.4, entitled "A Vehicle Shifting Device with High Reliability," discloses a shifting device capable of switching between H gear and sequential gear. A faceplate is provided on a fixed seat, and the faceplate is provided with an integrated gear slot that serves both H gear and sequential gear. The gear lever slides with the integrated gear slot via a support rod. A first positioning member is provided on the fixed seat, and the first positioning member cooperates with the positioning platform of the rotating seat to fix the rotating seat. The gear lever can only swing in one direction, thereby achieving the switch from H gear mode to sequential gear mode. This patent uses a universal faceplate to switch from H gear mode to sequential gear mode by limiting the rotation of the gear lever and the gear rod. The advantages of this shifting mode are simple structural design, easy assembly and disassembly, and easy repair, maintenance, and replacement of components. However, there is no clear distinction between the front and rear gear shifting actions of the gear lever in the two modes. That is, the H gear mode requires the gear lever to be accurately and stably engaged in the front and rear gear slots, while the sequential gear requires the gear lever to quickly and accurately return to the middle position after the front and rear gears are engaged. Traditional shifting devices still have the above problems and need improvement. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a dual-mode gear shifter that can simultaneously meet the gear shifting requirements of the H gear mode and the sequential gear mode, and improve the gear shifting accuracy and feel in the corresponding modes.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: a dual-mode gear shifter includes a base, a gear lever, a front swing arm, a rear swing arm, an elastic member and a limit member;

[0005] The gear lever, the front swing arm and the rear swing arm are all rotatably mounted on the base, the front swing arm and the rear swing arm are respectively located on both sides of the gear lever, and the elastic member is respectively connected to the front swing arm and the rear swing arm;

[0006] The limiting member is movably arranged on the base;

[0007] There is a gap between the front swing arm and the rear swing arm for accommodating the limiting member.

[0008] Furthermore, the front swing arm and the rear swing arm are respectively in contact with both sides of the gear lever, and the elastic member is in a stretched state.

[0009] Furthermore, the gear lever is provided with a shift block, and the shift block is located between the front swing arm and the rear swing arm.

[0010] Furthermore, the limiting member includes a cam, the cam is rotatably connected to the base, and the cam is located between the front swing arm and the rear swing arm.

[0011] Furthermore, the width of the gap between the front swing arm and the rear swing arm is less than or equal to the maximum outer diameter of the cam.

[0012] Furthermore, the limiting member further includes a knob, which is rotatably arranged on the base and is coaxially connected to the cam.

[0013] Furthermore, the front swing arm and the rear swing arm are both provided with notches at the cam.

[0014] Furthermore, the elastic member is respectively connected to the free end of the front swing arm and the free end of the rear swing arm, the middle of the front swing arm and the middle of the rear swing arm are respectively located on both sides of the gear lever, and the other end of the front swing arm and the other end of the rear swing arm are hinged to the base.

[0015] Furthermore, a spring top bead is provided on the base, an auxiliary positioning groove is provided on the gear lever, and the spring top bead abuts against the auxiliary positioning groove.

[0016] Furthermore, the rotation axes of the gear lever, the front swing arm and the rear swing arm are parallel to each other, and the axis of the elastic member is perpendicular to the rotation axis of the gear lever.

[0017] The beneficial effect of the present invention is that it provides a dual-mode gear shifter, in which a front swing arm and a rear swing arm that can swing back and forth are respectively installed in front of and behind the gear lever. The front swing arm and the rear swing arm can abut the gear lever, or leave a gap between them. The front swing arm and the rear swing arm are connected by an elastic part. After the movable limit piece is filled in the gap between the front swing arm and the rear swing arm, when the external force causes the gear lever to swing and push the front swing arm to rotate, the elastic piece is deformed, but the rear swing arm will not rotate with the front swing arm under the restriction of the limit piece. Therefore, the elastic piece continues to deform and exerts a restoring force on the front swing arm. When the external force acting on the gear lever disappears, under the elastic force of the elastic piece, the front swing arm begins to reset and drives the gear lever to return to its original position. This form meets the requirements of the sequential gear shifting mode; when the limit piece does not fill the gap between the front swing arm and the rear swing arm, that is, there is space for the front swing arm and the rear swing arm to swing in the gap between the front swing arm and the rear swing arm. When the external force causes the gear lever to swing and push the front swing arm to rotate, the elastic piece will not be significantly deformed. It is only used to pull the rear swing arm so that it will rotate with the front swing arm. When the external force acting on the gear lever disappears, the front swing arm and the rear swing arm will not reset, and the gear lever remains stable after being engaged in the gear slot. This form meets the requirements of the H gear shifting mode. The dual-mode shifter provided by the present invention can switch between the H-gear shift mode and the sequential gear shift mode. The H-gear mode gear lever after switching can be accurately and stably engaged in the front and rear gear slots. The sequential gear mode gear lever can quickly and accurately return to the middle position after engaging the front and rear gears. With the coordinated action of the limiter, front swing arm, rear swing arm and elastic member, the stability and reliability of the dual-mode shift device are improved, the shaking of the gear lever is reduced, and the gear shifting accuracy and feel in the corresponding mode are improved.

[0026] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0027] The present invention provides a dual-mode gear shifter, which is applied to a vehicle gear shifting device.

[0028] Please refer to Figures 1 to 6 , a dual-mode gear shifter includes a base 1, a gear lever 2, a front swing arm 3, a rear swing arm 4, an elastic member 5 and a limit member 6;

[0029] The gear lever 2, the front swing arm 3 and the rear swing arm 4 are all rotatably mounted on the base 1. The front swing arm 3 and the rear swing arm 4 are respectively located on both sides of the gear lever 2. The elastic member 5 is respectively connected to the front swing arm 3 and the rear swing arm 4.

[0030] The limiting member 6 is movably arranged on the base 1;

[0031] There is a gap between the front swing arm 3 and the rear swing arm 4 to accommodate the limiting member 6.

[0032] From the above description, it can be seen that the beneficial effects of the present invention are: providing a dual-mode gear shifter, in which a front swing arm 3 and a rear swing arm 4 that can swing back and forth are respectively installed in front of and behind the gear lever 2, and the front swing arm 3 and the rear swing arm 4 can abut against the gear lever 2, or leave a gap between the gear lever 2, and the front swing arm 3 and the rear swing arm 4 are connected by an elastic member 5. After the movable limiting member 6 is filled in the gap between the front swing arm 3 and the rear swing arm 4, when an external force causes the gear lever 2 to swing and pushes the front swing arm 3 to rotate, the elastic member 5 is deformed, but the rear swing arm 4 will not rotate with the front swing arm 3 under the restriction of the limiting member 6, so the elastic member 5 continues to deform and exerts a restoring force on the front swing arm 3. When the external force acting on the gear lever 2 disappears, under the elastic force of the elastic member 5, the front swing arm 3 begins to reset and drives the gear lever 2 to return to its initial position. This form meets the requirements of the sequential gear shifting mode; the limiting member 6 When the gap between the front swing arm 3 and the rear swing arm 4 is not filled, that is, there is space for the front swing arm 3 and the rear swing arm 4 to swing, when an external force causes the gear lever 2 to swing and push the front swing arm 3 to rotate, the elastic member 5 will not undergo significant deformation, but only serves to pull the rear swing arm 4 so that it will rotate with the front swing arm 3. When the external force acting on the gear lever 2 disappears, the front swing arm 3 and the rear swing arm 4 will not reset, and the gear lever 2 remains stable after being engaged in the gear slot. This form meets the requirements of the H gear engagement mode. The dual-mode gear shifter provided by the present invention can switch between the H gear engagement mode and the sequential gear engagement mode. After switching to the H gear engagement mode, the gear lever 2 can be accurately and stably engaged in the front and rear gear slots. The sequential gear engagement mode gear lever 2 can quickly and accurately return to the middle position after engaging the front and rear gears. Under the coordinated action of the limit member 6, the front swing arm 3, the rear swing arm 4 and the elastic member 5, the stability and reliability of the dual-mode gear shifting device are improved, the shaking of the gear lever 2 is reduced, and the gear engagement accuracy and feel in the corresponding mode are improved.

[0033] In an optional embodiment, the front swing arm 3 and the rear swing arm 4 are respectively in contact with both sides of the gear lever 2, and the elastic member 5 is in a stretched state.

[0034] From the above description, it can be seen that the front swing arm 3 and the rear swing arm 4 are clamped on both sides of the gear lever 2 under the action of the elastic member 5, which not only improves the gear shifting sensitivity, but also prevents the gear lever 2 from shaking and producing noise after the gear is engaged, thereby improving the gear shifting feel.

[0035] In an optional embodiment, the gear lever 2 is provided with a shift block 21 , and the shift block 21 is located between the front swing arm 3 and the rear swing arm 4 .

[0036] From the above description, it can be seen that the function of the shift block 21 is to shift the front swing arm 3 or the rear swing arm 4. The shift block 21 can be a plate-like structure parallel to the rotation axis of the front swing arm 3 and the rear swing arm 4, which can not only play a shifting effect, but also save space and materials.

[0037] In an optional embodiment, the limiting member 6 includes a cam 61 , which is rotatably connected to the base 1 , and the cam 61 is located between the front swing arm 3 and the rear swing arm 4 .

[0038] From the above description, it can be seen that the cam 61 is used as a limit member 6 by utilizing the characteristics of having a high surface and a low surface. When the two ends of the cam 61 with the largest outer diameter respectively rest on the front swing arm 3 and the rear swing arm 4, according to the above principle, it is the sequential gear shifting mode at this time; when there is a gap between the two ends of the cam 61 and the front swing arm 3 and the rear swing arm 4, according to the above principle, it is the H gear shifting mode at this time.

[0039] In an optional embodiment, the width of the gap between the front swing arm 3 and the rear swing arm 4 is less than or equal to the maximum outer diameter of the cam 61 .

[0040] From the above description, it can be seen that only when the distance between the front swing arm 3 and the rear swing arm 4 is less than or equal to the maximum outer diameter of the cam 61 can the front swing arm 3 and the rear swing arm 4 be ensured to be tightly attached to the two ends of the cam 61 with the maximum outer diameter, thereby improving the gear shifting sensitivity, and after the gear is engaged, the gear handle 2 will not shake or produce noise, thereby improving the gear shifting feel.

[0041] In an optional embodiment, the limiting member 6 further includes a knob 62 , which is rotatably disposed on the base 1 , and the knob 62 is coaxially connected to the cam 61 .

[0042] As can be seen from the above description, the knob 62 serves to facilitate the driver's operation. By rotating the knob 62, the cam 61 is driven to rotate, thereby quickly switching between the two gear modes.

[0043] In an optional embodiment, the front swing arm 3 and the rear swing arm 4 both have a notch 31 located at the cam 61 .

[0044] From the above description, it can be seen that the distance between the two notches 31 must ensure that its width is less than or equal to the maximum outer diameter of the cam 61. Under this premise, the notch 31 can increase the space for the front swing arm 3 and the rear swing arm 4 to swing, thereby improving the gear shifting feel in the H gear shifting mode and improving the gear shifting accuracy.

[0045] In an optional embodiment, the elastic member 5 is respectively connected to the free end of the front swing arm 3 and the free end of the rear swing arm 4, the middle of the front swing arm 3 and the middle of the rear swing arm 4 are respectively located on both sides of the gear lever 2, and the other end of the front swing arm 3 and the other end of the rear swing arm 4 are hinged to the base 1.

[0046] From the above description, it can be seen that the elastic member 5 is connected to the free end of the swing arm, and the gear lever 2 is in contact with the middle of the swing arm. The advantages of this arrangement are: 1. Compared with the method of contacting the free end of the swing arm, the gear lever 2 only needs to rotate a smaller angle to push the swing arm to swing, which not only ensures the gear shifting efficiency but also saves space; 2. Compared with the method of connecting to the middle of the swing arm, the elastic member 5 can improve the reset efficiency of the swing arm, and improve the gear shifting speed and feel.

[0047] In an optional embodiment, a spring top bead 11 is provided on the base 1 , and an auxiliary positioning groove 22 is provided on the gear lever 2 , and the spring top bead 11 abuts against the auxiliary positioning groove 22 .

[0048] It can be seen from the above description that the positioning cooperation between the spring top bead 11 and the auxiliary positioning groove 22 can help improve the shifting accuracy, stability and hand feel feedback of the gear lever 2.

[0049] In an optional embodiment, the rotation axes of the gear lever 2 , the front swing arm 3 and the rear swing arm 4 are parallel to each other, and the axis of the elastic member 5 is perpendicular to the rotation axis of the gear lever 2 .

[0050] As can be seen from the above description, setting the rotation axes of the gear lever 2 and the swing arm parallel to each other is beneficial to the transmission of force, thereby improving the sensitivity of gear shifting and the accuracy and efficiency of gear shifting.

[0051] The basic principle of the present invention is: through the rotation of the limit member 6, the swinging of the front swing arm 3 and the rear swing arm 4, and the restoring force provided by the elastic member 5, the gear lever 2 is controlled to have the ability to reset after rotation, thereby realizing the free switching between the H gear shift mode and the sequential gear shift mode.

[0052] Please refer to Figures 1 to 6 , Embodiment 1 of the present invention is: a dual-mode gear shifter, comprising a base 1, a gear lever 2, a front swing arm 3, a rear swing arm 4, an elastic member 5 and a limit member 6;

[0053] The gear lever 2, front swing arm 3 and rear swing arm 4 are all rotatably arranged on the base 1, and the front swing arm 3 and rear swing arm 4 are respectively located on both sides of the gear lever 2 facing the front gear position and the rear gear position, and the elastic member 5 is respectively connected to the front swing arm 3 and the rear swing arm 4; the limiting member 6 is movably arranged on the base 1; there is a gap between the front swing arm 3 and the rear swing arm 4 to accommodate the limiting member 6.

[0054] Please refer to Figures 1 to 6 The difference between the second embodiment of the present invention and the first embodiment is as follows:

[0055] The front swing arm 3 and the rear swing arm 4 are respectively in contact with the two sides of the gear lever 2, and the elastic member 5 is a spring, and the elastic member 5 is in a stretched state. The gear lever 2 is provided with a shift block 21, and the shift block 21 is located between the front swing arm 3 and the rear swing arm 4. The limiting member 6 includes a cam 61, and the cam 61 is rotatably connected to the base 1, and the cam 61 is located between the front swing arm 3 and the rear swing arm 4. The width of the gap between the front swing arm 3 and the rear swing arm 4 is less than or equal to the maximum outer diameter of the cam 61. The limiting member 6 also includes a knob 62, and the knob 62 is rotatably set on the base 1, and the knob 62 is coaxially connected to the cam 61. The front swing arm 3 and the rear swing arm 4 each have a notch 31 located at the cam 61. The notch 31 has a semicircular cross-section, and the radius of the notch 31 is greater than the distance from the rotation axis of the cam 61 to the inner wall of the notch 31. This maximizes the swing space for the front and rear swing arms 3 and 4. The elastic member 5 is connected to the free ends of the front and rear swing arms 3 and 4, respectively. The middle portions of the front and rear swing arms 3 and 4 are located on either side of the gear lever 2, respectively. The other ends of the front and rear swing arms 3 and 4 are hingedly connected to the base 1. A spring bead 11 is provided on the base 1, and the gear lever 2 is provided with an auxiliary positioning groove 22. The spring bead 11 abuts against the wavy positioning surface of the auxiliary positioning groove 22. The rotation axes of the gear lever 2, front swing arm 3, and rear swing arm 4 are parallel to each other, and the axis of the elastic member 5 is perpendicular to the rotation axis of the gear lever 2.

[0056] To sum up, the present invention provides a dual-mode gear shifter, in which a front swing arm and a rear swing arm that can swing back and forth are respectively installed in front of and behind the gear lever. The front swing arm and the rear swing arm can abut the gear lever, or leave a gap between them. The front swing arm and the rear swing arm are connected by an elastic part. After the movable limit piece is filled in the gap between the front swing arm and the rear swing arm, when the external force causes the gear lever to swing and push the front swing arm to rotate, the elastic piece is deformed, but the rear swing arm will not rotate with the front swing arm under the restriction of the limit piece. Therefore, the elastic piece continues to deform and exerts a restoring force on the front swing arm. When the external force acting on the gear lever disappears, under the elastic force of the elastic piece, the front swing arm begins to reset and drives the gear lever to return to its original position. This form meets the requirements of the sequential gear shifting mode; when the limit piece does not fill the gap between the front swing arm and the rear swing arm, that is, there is space for the front swing arm and the rear swing arm to swing in the gap between the front swing arm and the rear swing arm. When the external force causes the gear lever to swing and push the front swing arm to rotate, the elastic piece will not be significantly deformed. It is only used to pull the rear swing arm so that it will rotate with the front swing arm. When the external force acting on the gear lever disappears, the front swing arm and the rear swing arm will not reset, and the gear lever remains stable after being engaged in the gear slot. This form meets the requirements of the H gear shifting mode. The dual-mode shifter provided by the present invention can switch between the H-gear shift mode and the sequential gear shift mode. The H-gear mode gear lever after switching can be accurately and stably engaged in the front and rear gear slots. The sequential gear mode gear lever can quickly and accurately return to the middle position after engaging the front and rear gears. With the coordinated action of the limiter, front swing arm, rear swing arm and elastic member, the stability and reliability of the dual-mode shift device are improved, the shaking of the gear lever is reduced, and the gear shifting accuracy and feel in the corresponding mode are improved.

[0057] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's description and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
