DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example

[0021] like Figure 1 and Figure 2 As shown, an electric vehicle motor with an adjustment function proposed in an embodiment of the utility model includes a drive shaft 1 and a track plate 7 installed on the frame of the electric vehicle. The drive shaft 1 is used to drive the electric vehicle to operate. A spline shaft 2 is integrally formed at one end of the drive shaft 1. When the spline shaft 2 rotates, the drive shaft 1 is driven to rotate to realize the rotation drive of the drive shaft 1. A drive box 3 is arranged on the spline shaft 2. The drive box 3 can drive the spline shaft 2 to rotate. It should be noted that the drive box 3 can move along the spline shaft 2. The drive box 3 is slidably connected to the track plate 7. The track plate 7 can realize the sliding limit of the drive box 3, so that the drive box 3 moves. The drive box 3 includes a protective shell 301 slidably connected to the track plate 7, and a driving gear 306 and a passive gear 303 rotatably connected to the inner side of the protective shell 301. The protective shell 301 is the outer protection part of the drive box 3. The driving gear 3 A tooth chain 305 is arranged between 06 and the passive gear 303. When the active gear 306 rotates, the passive gear 303 can be driven to rotate on the inner side of the protective shell 301 through the relationship of the tooth chain 305. A motor body 4 is installed on the outer wall of the protective shell 301. The output shaft of the motor body 4 is fixedly connected to the active gear 306 to realize the rotational drive of the active gear 306. A protrusion 5 is integrally formed on the outer wall of the spline shaft 2. A spline groove 304 adapted to the protrusion 5 is opened at the passive gear 303 corresponding to the protrusion 5. The spline shaft 2 is driven to rotate through the relationship between the protrusion 5 and the spline groove 304, and the matching relationship does not hinder the overall movement of the drive box 3. After the drive box 3 moves, the rotational drive of the spline shaft 2 and the drive shaft 1 can also be realized through the relationship between the protrusion 5 and the spline groove 304. In this way, the movement of the motor body 4 is realized, which is convenient for the inspection and maintenance of the motor body 4 and has good convenience.

[0022] like Figure 1 and Figure 2 As shown, in some embodiments, a sliding block 307 is fixedly connected to the side wall of the protective shell 301, and the sliding block 307 is slidably connected to the track groove 8 correspondingly opened on the track plate 7, thereby realizing a limiting effect when the drive box 3 moves, thereby ensuring the linear movement of the drive box 3 and the motor body 4.

[0023] like Figure 1 and Figure 2As shown, in some embodiments, a screw rod 9 is rotatably connected to the track groove 8 of the track plate 7, one end of the screw rod 9 extends to the outside of the track plate 7 and is fixed with a handwheel 10, and a screw hole adapted to the screw rod 9 is opened at the sliding block 307 corresponding to the screw rod 9; this method can realize the driving function of the drive box 3 and the motor body 4 to move, and the setting of the handwheel 10 can drive the screw rod 9 to rotate. Since the screw rod 9 and the sliding block 307 are threadedly connected, when the screw rod 9 rotates, the sliding block 307 can be controlled to slide in the track groove 8 of the track plate 7, thereby realizing the movement of the drive box 3 and the motor body 4 and the adjustment of the position of the motor body 4.

[0024] like Figure 1 As shown, in some embodiments, a stop plate 6 is fixedly connected to one end of the spline shaft 2 away from the drive shaft 1 . The setting of the stop plate 6 can serve as a stop and limit function for the protective shell 301 to prevent the drive box 3 from separating from the spline shaft 2 .

[0025] like Figure 1 and Figure 2 As shown, in some embodiments, a clearance cavity 302 is opened at the protective shell 301 corresponding to the spline shaft 2 to enable the protective shell 301 to slide on the spline shaft 2.

[0026] The working principle and use steps of the utility model are as follows: when the position of the motor body 4 needs to be adjusted to realize the inspection and maintenance of the motor body 4, the hand wheel 10 is turned to make the screw rod 9 rotate on the track plate 7. At this time, the sliding block 307 slides at the track groove 8 of the track plate 7 to realize the movement of the overall position of the drive box 3 and the motor body 4. Since the active gear 306 and the passive gear 303 are both rotatably connected to the inner side of the protective shell 301, when the protective shell 301 moves, the synchronous movement of the passive gear 303 and the active gear 306 can be realized. The inner side of the passive gear 303 is provided with a spline groove 304, and the spline groove 304 is adapted to the protrusion 5 on the spline shaft 2. The passive gear 303 is driven to rotate through the relationship between the protrusion 5 and the spline groove 304. Therefore, after the position of the drive box 3 is adjusted, the rotation drive of the spline shaft 2 is not affected, and the drive box 3 does not need to be disassembled, thereby improving convenience.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
