It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 to 4, an embodiment of the present invention provides a toothed plate 1, which includes a body 11 and a clip 13, a concave toothed surface 12 is provided on the body 11, the clip 13 is disposed on the outer sidewall of the body 11, and one end of the body 11, which is far away from the clip 13, is provided with a zigzag clamping portion 131. Understandably, the number of the clips 13 may be plural.

The toothed plate 1 in the above embodiment is designed to be separated from other mechanisms (see fig. 5 and 6, such as the handle assembly 2, etc.) in the shift positioning device, so that when the tooth socket shape of the tooth surface 12 of the toothed plate 1 in the shift positioning device needs to be adjusted, only the toothed plate 1 with different tooth socket shapes needs to be designed, and the toothed plate 1 with different tooth socket shapes is assembled in the housing 1 (the integral re-mold opening of the toothed plate 1 and the handle assembly 2 is not needed), which can greatly reduce the cost of developing the mold, shorten the development cycle, and improve the efficiency; meanwhile, the clip 13 of the toothed plate 1 is provided with the serrated clamping portion 131, and referring to fig. 7, when the toothed plate 1 moves and presses the clip 13 to deform, the serrated clamping portion 131 can be attached to the groove wall of the mounting groove 41 at any time, so that the toothed plate 1 can be firmly assembled on the housing 4 through the serrated clamping portion 131, and looseness between the toothed plate 1 and the housing 4 is avoided.

In an embodiment, as shown in fig. 1 to 7, an elastic sheet 14 is further disposed on an outer side wall of the body 11, the elastic sheet 14 includes a connecting portion 141 and an abutting portion 142, and the elastic sheet 14 is connected to the body 11 through the connecting portion 141. Understandably, the outer side wall of the body 11 is provided with a plurality of sets of the elastic pieces 14, and two elastic pieces 14 of each set are oppositely arranged at two sides of the body 11. That is, the number of the elastic sheets 14 may be multiple, the elastic sheets 14 are divided into multiple groups, and each group of the elastic sheets 14 is disposed on two opposite sides of the body 11 (preferably, symmetrically disposed); in an embodiment, as shown in fig. 2, the abutting portion 142 is provided with an abutting surface 1421 parallel to the outer side wall of the body 11, when the elastic piece 14 abuts against the housing 4, the abutting surface 1421 abuts against the housing 4, that is, the elastic piece 14 abuts against the housing 4 through the abutting surface 1421, so that the housing 4 always abuts against the abutting portion 142 of the toothed plate 1 in the directions of the two opposite sides of the body 11, thereby avoiding the shaking of the toothed plate 1 in the housing 4, and further effectively avoiding the problem of a sharp shift feeling and a abnormal shift noise during the gear shifting process; meanwhile, the elastic sheets 14 are arranged on two opposite sides of the body 11, and impact between the shell 4 and the toothed plate 1 can be buffered in the gear shifting process, so that abrupt force cannot occur in the gear shifting process.

That is, when the elastic piece 14 abuts against the housing 4, if the abutting portion 142 of the elastic piece 14 is pressed by the housing 4 abutting against the elastic piece 14 during the gear shifting process, at this time, a part or all of the abutting portion 142 can be accommodated in the accommodating groove 15 by the pressing force of the housing 4, so as to avoid interference with the gear shifting process.

In one embodiment, the material of the castellated plate 1 is Polyoxymethylene (POM). Because polyformaldehyde is a smooth, glossy hard and fine and close material in surface, and its self-lubricating effect is good, consequently, use during the location of shifting, need not to paint lubricating grease and can guarantee the lubricated effect between handle components 2 and the castellated plate 1 at the mutual motion in-process, avoided the friction abnormal sound that causes in the motion process.

In an embodiment, as shown in fig. 2, 3 and 7, a limiting column 16 is disposed on a side of the body 11 facing away from the toothed surface 12; the radial section of the limiting column 16 is gradually reduced from one end connected with the body 11 to the end far away from the body 11. That is, the limiting column 16 in this embodiment is conical, and one end of the limiting column connected to the body 11 is a larger end; when the tooth plate 1 is assembled into the shift positioning device, the limiting column 16 can be inserted into the positioning hole 42 shown in fig. 7, so that the positioning of the tooth plate 1 in the axial direction of the limiting column 16 is completed; the tapered design can facilitate the better insertion of the limiting column 16 into the positioning hole 42, and simultaneously can facilitate the complete demolding of the toothed plate 1 from the mold, thereby avoiding the influence of insufficient draft angle on the precision of the positioning column 16. Preferably, as shown in fig. 2, the limiting column 16 is provided with a reinforcing rib 17. The design of the reinforcing ribs 17 can enhance the strength of the limiting columns 16.

In an embodiment, as shown in fig. 1 and fig. 2, at least one set of the guiding portions 18 is further protruded on the outer side wall of the body 11, and two guiding portions 18 of each set are oppositely disposed on two sides of the body 11. The toothed plate 1 can be guided and fitted better into the housing 4 in the predetermined position by the guide 18. The lead-in portion 18 is a projection with an inclined surface or an arc surface, and is disposed on the outer side wall of the body 11. The number of the introduction portions 18 may be one or two or more, and the distribution positions thereof may be set as required.

On the other hand, as shown in fig. 1 to 7, the embodiment of the present invention further provides a gear shift positioning device, which includes a handle assembly 2, a rotating shaft 3, a housing 4 and the above-mentioned toothed plate 1; the toothed plate 1 is clamped on the shell 4, and the handle assembly 2 is rotatably connected to the shell 4 through the rotating shaft 3; the handle assembly 2 comprises a bullet 21, the bullet 21 abuts against the toothed surface 12, and the bullet 21 can slide along the toothed surface 12; be equipped with mounting groove 41 on the casing 4, checkpost 13 inlay card is in mounting groove 41, just joint portion 131 with the cell wall laminating of mounting groove 41.

In the present embodiment, the toothed plate 1 is provided as a separate design from other mechanisms in the shift positioning device (refer to fig. 5 and 6, such as the handle assembly 2, etc.); when the tooth socket shape on the tooth surface 12 of the tooth-shaped plate 1 needs to be adjusted, only the tooth-shaped plates 1 with different tooth socket shapes need to be designed, and the tooth-shaped plates 1 with different tooth socket shapes are assembled in the shell 1, so that the cost for developing a die can be greatly reduced, the development period is shortened, and the efficiency is improved; meanwhile, the clip 13 of the toothed plate 1 is provided with the serrated clamping portion 131, referring to fig. 7, when the toothed plate 1 moves and presses the clip 13 to deform, the serrated clamping portion 13 can be attached to the groove wall of the mounting groove 41 at any time, and therefore, the toothed plate 1 can be firmly assembled on the housing 4 through the serrated clamping portion 131, and looseness between the toothed plate 1 and the housing 4 is avoided.
