Description of the invention: [Technical field to which the invention pertains] - The present invention relates to a vehicle gear shifting mechanism, and more particularly to a vehicle gear shifting mechanism that is easier to assemble. [Prior Art] Referring to FIG. 1A and FIG. 1B , a conventional vehicle gear mechanism φ 1 mainly includes a casing 10 , a first gear gear 11 , a second gear gear 12 , and a gear drum 13 . A gear shifting block 14, a shifting fork 15, a shifting fork shaft 16, a drive motor 17, a reduction gear set 18, a link set 19 and a drive arm 20. The gear shifting slider 14 is disposed between the first gear gear 11 and the second gear gear 12, and the gear slider 14 is formed with a plurality of bumps 14a. The first gear gear 11 is formed with a plurality of grooves 11a, and the second gear gear 12 is also formed with a plurality of grooves (not shown). The shift fork 15 is slidably disposed on the shift fork shaft 16 and the shift fork 15 is coupled to the shift slider 14. The shift drum 13 is formed with a curved chute 13a, and one end portion 15a of the shift fork 15 is slidable in the curved chute 13a. The drive motor 17 is coupled to a reduction gear set 18 that is eccentrically coupled to the link set 19, the link set 19 is coupled to the drive arm 20, and the drive arm 20 is coupled to the shift drum 13. When the gear shifting operation is performed by the vehicle shifting mechanism 1, the drive motor 17 is operated to transmit the power to the link group 19 via the reduction gear set 18. Then, the link set 19 drives the drive arm 20 to rotate, thereby causing the shift drum 13 connected to the drive 0134-A21581 TWF (N2); 95-TOP-10; hawdong 5 1294838 i < At this time, the end portion 15a of the shift fork 15 is slid in the curved chute 13a by the rotation of the shift drum 13, so that the shift fork 15 can be moved on the shift fork shaft 16. The shift fork 15 that moves on the shift fork shaft 16 will in turn force the shift slider 14 to move with it, so that the bump 14a on the drain slider 14 can be selectively engaged with the first gear position. The groove 11a on the gear 11 or the groove on the second gear position 12. As described above, the gear shifting operation of the vehicle gear mechanism 1 is completed. However, the conventional vehicle gear mechanism 1 has a number of disadvantages. First, because the drive motor 17 has a high rotational speed and a small output torque, it must be decelerated via the reduction gear set 18 to increase its output torque to drive the components such as the shift drum 13 and the shift fork 15. However, the provision of the drive motor 17, the reduction gear set 18, the link set 19 and the drive arm 20 in the casing 10 of the vehicle gear shifting mechanism 1 makes the casing 10 too bulky, which is disadvantageous for assembly on the vehicle. Secondly, there are too many components in the vehicle gear shifting mechanism 1 (that is, the vehicle gear shifting mechanism 1 includes components such as the drive motor 17, the reduction gear set 18, the φ link set 19, and the drive arm 20), which increases the manufacturing cost and assembly. The complexity. In view of the above, an object of the present invention is to provide a vehicle gear shifting mechanism which can have advantages such as miniaturization, ease of assembly, and low manufacturing cost.

In more detail, the gear shift drum 120 further has a first end portion 121 and a second end portion 122, the first end portion 121 is opposite to the second end portion 122, and the curved chute 123 is located at the end portion 121 is between the second end 122. As shown in Figs. 2A and 2B, the reduction unit 13A is disposed outside the casing 110 and is detachably coupled to the shift drum 12A. In addition, the reduction unit 丨3〇 has a mast 131, a boring wheel 132 and a cover 133, the worm 131 is engaged with the boring wheel 132, and the worm wheel 13:2 is detachably connected to the gear shifting drum 12〇 . More specifically, the worm gear 132 retracts with a central shaft 132a that is detachably coupled to the first end 121 of the gear shift drum 120. Specifically, a slot 132b (as shown in Fig. 2A) is formed on the central shaft 132a of the wheel 132, and the cover 133 is opposed to the slot 132b. The drive motor 140 is disposed outside the casing no, and the drive motor 140 is coupled to the reduction unit 130 to drive the shift drum 12 to rotate. In more detail, the drive motor 14A is connected to the worm 13 of the reduction unit 13 此外. Moreover, it is worth noting that the drive motor 140 and the reduction unit 13 〇 may be of an integral structure (ie, a motor reducer) And it is locked on the case 11〇 by a plurality of nuts 195. As shown in FIG. 2B, the gear shifting fork shaft 17〇 and the gear shifting fork 18〇 are also disposed in the casing 1丨〇, and the gear shifting 18〇 is slidably disposed on the gear shifting fork shaft 170. Above and sliding on the shift drum 12〇 bend: 0134-A21581TWF (N2); 95-T〇P~1〇; hawdong 8 1294838 l 'in the chute 123. In more detail, the shift fork 180 is slid in the curved chute 123 of the shift drum 120 with its one end portion 181. The first gear gear 150 and the second gear gear 160 are also disposed within the tank body 110. It should be noted that although the present embodiment is exemplified by two gear positions - gears 150, 160, it may alternatively have more gear gears. The gearshift slider 190 is also disposed within the housing 110, and the gear slider 190 is coupled to the gear shifting fork 180.

Then, the inserter can insert a simple tool (e.g., a flat-shaped screwdriver) into the slot n2b on the central shaft 132a of the worm wheel 132 to rotate the center-axis 132a. As described above, the shifting drum attached to the center shaft 132a can be rotated to force the shifting fork 18 and the shifting slider 19 to perform gear shifting, so that the operator can drive the vehicle to the maintenance site for maintenance. In summary, the vehicle gear mechanism 1 disclosed in the present invention has many features. First, since the drive motor 14〇 and the reduction unit 13〇 (motor reducer) are connected to the shift drum 12〇 from the outside of the casing 110, the configuration of the shift gear set, the link group, and the drive arm can be omitted, and thus η制造 The manufacturing cost, the volume, and the assembly of the vehicle gear shifting mechanism 100 are secondarily lower. Since the driving motor 140 and the speed reducing unit 130 are installed outside the casing 110, the casing can be reduced. The paper of the body u), the meat of the moon, can facilitate the assembly of the vehicle gear mechanism 100 on the vehicle. Moreover, the conventional speed reduction mechanism needs to be matched by a plurality of spur gears to achieve the phase ratio of the drum. The speed reduction unit 130 of the vehicle gear mechanism 100 is reduced by the configuration of the worm 131 and the wheel 132 only by the need. , you can change the power transmission loose ', the direction of the 珣, and the configuration of a wheel 132 can achieve the high reduction ratio of the grasshopper 131 a 曰 ... one. In addition, the drive motor 140 can be disposed laterally on the casing 110 and even close to the casing 110, so that it can be evenly attached to the casing 110. The size of the vehicle gearshift mechanism 100 is further reduced, which in turn facilitates assembly on the vehicle. In addition, since the drive motor 140 and the speed reducer 130 (motor reducer) are disposed outside the casing 110 - that is, the drive motor 140 and the speed reduction unit 130 (motor reducer) are provided by a plurality of nuts 195 It is locked on the casing 110, so that the drive motor 140 and the reduction unit 130 (motor reducer) are easily disassembled. Although the present invention has been disclosed in its preferred embodiments, it is not intended to limit the present invention, and it is possible to make some modifications and refinements without departing from the spirit and scope of the present invention. The scope of the invention is defined by the scope of the appended claims.
