Description

TECHNICAL FIELD

[0001] The utility model relates to an automobile parts technical field, concretely relates to a gear shifting device. BACKGROUND

[0002] The automobile gear shifter is the necessary component of modern automobile, and the gear shifter matches the automobile engine rotating speed and the wheel rotating speed through the action of hand, so that the automobile can give consideration to the large torque in low speed and the high speed in high speed.

[0003] In the prior art, the electronic gear shifter comprises a shell, a gear shifting lever, a magnet and a PCB board. The upper and lower ends of the shell are hinged to the whole vehicle through a rotating shaft. A through hole is formed in the shell for the gear shifting lever to pass through. The first end of the gear shifting lever is arranged in the through hole and extends to the outside of the shell. The gear shifting lever is hinged to the shell through a pin shaft extending in the left-right direction. The magnet is installed on the first end of the gear shifting lever and located outside the shell. The PCB board is fixed on the whole vehicle and located below the magnet.

[0004] The shell can swing left and right around the rotating shaft, so that the gear shifting lever can swing left and right. The gear shifting lever can swing up and down around the pin shaft. Therefore, the magnet fixed on the gear shifting lever can move not only in the horizontal direction but also in the vertical direction. However, when the gear shifting lever swings up and down, the displacement of the first end of the gear shifting lever changes little, which leads to a small displacement change of the magnet in the vertical direction. Therefore, the recognition accuracy of the PCB board needs to be high. If the recognition accuracy of the PCB board is low, the recognition of the PCB board is likely to be wrong. If the length of the first end of the gear shifting lever is extended to increase the displacement change of the first end, the space occupied by the gear shifter increases, which affects the assembly of other components of the whole vehicle.

[0045] In one aspect, the present application discloses a shift device. The shift device is suitable for being assembled on a whole vehicle.

[0046] Please refer to Figures 1-4 As shown in the figure, the shift device comprises a shell 1, a shift lever 2, a connecting piece 3, a PCB board 4, a pin shaft 5 and a magnet 6. The shell 1 is provided with a first rotating shaft 11. The first rotating shaft 11 is suitable for being hinged on the whole vehicle. The shell 1 is provided with a through hole 12 for the shift lever 2 to pass through. The first end of the shift lever 2 is arranged in the through hole 12 and extends out of the shell 1.

The connecting piece 3 comprises two side plates and a connecting portion connecting the two side plates. The side plate of the connecting piece 3 is provided with a second rotating shaft 31. The side plate of the connecting piece 3 is hinged to the shell 1 through the second rotating shaft 31. The axis direction of the second rotating shaft 31 is parallel to the axis direction of the pin shaft 5. The first end of the shift lever 2 is arranged in the inner cavity of the connecting piece 3. The side plate of the connecting piece 3 is provided with a sliding groove 32. The side plate of the connecting piece 3 is slidingly connected with the shift lever 2 through the sliding groove 32. The sliding groove 32 extends along the length direction of the through hole 12. The end of the connecting piece 3 away from the shell 1 is assembled with the magnet 6. The magnet 6 is suitable for cooperating with the PCB board 4. The PCB board 4 is suitable for being assembled on the whole vehicle.

[0048] The PCB 4 is provided with a Hall chip for sensing the magnetic flux change of the magnet 6. The cooperation between the PCB 4 and the magnet 6 is known in the art, and thus will not be described herein.

[0049] In the embodiment, the first rotating shaft 11 is two, arranged at the upper and lower ends of the shell 1. The first rotating shaft 11 extends in the up-down direction. The through hole 12 extends in the front-back direction. The pin shaft 5 extends in the left-right direction. The two side plates of the connecting piece 3 are located on the left and right sides of the connecting piece 3, and the connecting part of the connecting piece 3 connects the lower ends of the two side plates. The magnet 6 is assembled in the connecting part of the connecting piece 3. The second rotating shaft 31 extends in the left-right direction. The sliding groove 32 is two, arranged on the corresponding side plate. The sliding groove 32 extends in the front-back direction. The PCB 4 is arranged below the magnet 6.

[0050] In the embodiment, the working principle of the shifting device is as follows:

[0051] The shell 1 can swing left and right around the first rotating shaft 11, so that the shifting rod 2 and the connecting piece 3 can swing left and right.

[0052] The shifting rod 2 can swing up and down around the pin shaft 5, so that the connecting piece 3 swings up and down under the cooperation of the sliding groove 32 and the shifting rod 2. The through hole 12 is suitable for limiting the up-down swing amplitude of the shifting rod 2.

[0053] As described above, through the cooperation of the sliding groove 32 and the shifting rod 2, the magnet 6 can effectively amplify the movement trajectory of the first end of the shifting rod 2, that is, when the shifting rod 2 swings up and down, the magnet 6 can effectively amplify the displacement change of the first end of the shifting rod 2 in the vertical direction through the connecting piece 3, thereby amplifying the recognition angle of the device, so that the movement of the magnet 6 can more effectively feedback the swing situation of the shifting rod 2, so that the recognition of the device is more accurate.

[0054] Further, as shown in Figure 3 and Figure 7 , the sliding groove 32 is located between the second rotating shaft 31 and the pin shaft 5 to slide and limit the shifting rod 2. Specifically, the side plate of the connecting piece 3 extends into the through hole 12. The left and right sides of the shifting rod 2 are provided with sliding protrusions 21 which cooperate with the sliding groove 32. The sliding groove 32 is suitable for sliding and limiting the sliding protrusions 21.

[0056] Further, please refer to Figure 3And Figure 6 As shown in the figure, the housing 1 is provided with an exposure hole 13. The exposure hole 13 is adapted to expose the sliding protrusion 21, so that the worker can overhaul the connection between the sliding groove 32 and the sliding protrusion 21.

[0057] Further, please refer to Figure 4 And Figure 5 As shown in the figure, the connecting piece 3 is provided with a mounting groove 33. The mounting groove 33 is located at the end of the connecting piece 3 away from the shift lever 2. In this embodiment, the mounting groove 33 is provided on the connecting portion of the connecting piece 3. The mounting groove 33 has an open end and a closed end. The open end of the mounting groove 33 is in communication with the inner cavity of the connecting piece 3, that is, the upper end of the mounting groove 33 is the open end. The inner wall of the mounting groove 33 is provided with a plurality of limiting protrusions 34. When the magnet 6 is placed in the mounting groove 33, the limiting protrusions 34 are in interference fit with the side wall of the magnet 6 to fix the magnet 6.
