[0083] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the fifth gear 85 is loosely sleeved on the first transmission shaft 30. That is to say, the first transmission shaft 30 is inserted through the fifth gear 85, but the first transmission shaft 30 and the fifth gear 85 are not directly connected. This arrangement can make the structure of the drive assembly 100 reasonable, which is conducive to the compact design of the drive assembly 100, thereby improving space utilization.

[0084] As some embodiments of the present application, Figure 1 and Figure 2 As shown, the drive assembly 100 may further include: a sixth gear 86, which is meshed between the fourth gear 84 and the fifth gear 85. This arrangement can ensure smooth and stable power transmission between the first motor 40 and the shift mechanism 20. As some embodiments of the present application, Figure 1 and Figure 2 As shown, the sixth gear 86 can be empty on the second transmission shaft 60, that is, the second transmission shaft 60 is inserted into the sixth gear 86, but the second transmission shaft 60 and the sixth gear 86 do not have a direct connection relationship. Such an arrangement can make the structural form of the drive assembly 100 reasonable, which is conducive to the compact design of the drive assembly 100, thereby improving space utilization.
