2 . The apparatus according to claim 1 , further comprising:
an adjustment pin, wherein an axis of the adjustment pin coincides with the first axis; and a tension pulley, wherein the tension pulley is disposed on the adjustment pin, and an outer circumferential surface of the tension pulley abuts against the transmission belt.

3 . The apparatus according to claim 2 , wherein the axis of the drive pulley, an axis of the driven pulley, the axis of the adjustment pin are in parallel, and a relative position between the axis of the driven pulley and the first axis remains unchanged.

4 . The apparatus according to claim 2 , wherein the apparatus further comprises a first motor and a housing, the first motor is configured to drive the drive pulley, and the first motor is mounted on the housing by using the adjustment pin.

5 . The apparatus according to claim 4 , wherein the first motor further comprises a first chamber, the adjustment pin further comprises a through hole, a first end of the through hole is located in the first chamber, a second end of the through hole is located outside the first motor, and the first chamber is connected to an outside of the first motor through the through hole.

6 . The apparatus according to claim 5 , wherein the housing is enclosed to form a second chamber, and the drive pulley, the driven pulley, and the adjustment pin are accommodated in the second chamber; and
that the first chamber is connected to an outside of the first motor through the through hole specifically comprises: the first chamber is connected to the second chamber through the through hole.

7 . The apparatus according to claim 5 , wherein an axis of the through hole coincides with the axis of the adjustment pin.

8 . The apparatus according to claim 4 , wherein the first motor further comprises a first fastening part, and the first motor is fixedly connected to the housing by using the first fastening part.

9 . The apparatus according to claim 8 , wherein that the first motor further comprises a first fastening part specifically comprises: the first motor comprises at least one bolt hole; and the first motor is relatively fastened to the housing through a bolt connection.

10 . The apparatus according to claim 4 , wherein the apparatus further comprises a second motor, and the second motor and the first motor jointly drive the drive pulley.

11 . The apparatus according to claim 4 , wherein the adjustment pin further comprises a positioning end face, and the positioning end face is configured to abut against the housing.

12 . A method applied to an apparatus, wherein the apparatus comprises a drive pulley, a driven pulley, and a transmission belt, the drive pulley is connected to the driven pulley by using the transmission belt, and an axis of the drive pulley is configured to rotate around a first axis,
and wherein the method comprises: adjusting a rotation angle of the drive pulley rotating around the first axis; and in response to determining that tension of the transmission belt is greater than a first tension threshold, fixedly connecting a first motor to a housing.

13 . The method according to claim 12 , wherein the method further comprises:
disconnecting a fixed connection between the first motor and the housing.

14 . A vehicle comprising an apparatus wherein the apparatus comprises a drive pulley, a driven pulley, and a transmission belt, the drive pulley is connected to the driven pulley by using the transmission belt, and an axis of the drive pulley is configured to rotate around a first axis.

15 . The vehicle according to claim 14 , wherein the apparatus further comprises:
an adjustment pin, wherein an axis of the adjustment pin coincides with the first axis; and a tension pulley, wherein the tension pulley is disposed on the adjustment pin, and an outer circumferential surface of the tension pulley abuts against the transmission belt.

16 . The vehicle according to claim 15 , wherein the axis of the drive pulley, an axis of the driven pulley, the axis of the adjustment pin are in parallel, and a relative position between the axis of the driven pulley and the first axis remains unchanged.

17 . The vehicle according to claim 15 , wherein the apparatus further comprises a first motor and a housing, the first motor is configured to drive the drive pulley, and the first motor is mounted on the housing by using the adjustment pin.

18 . The vehicle according to claim 17 , wherein the first motor further comprises a first chamber, the adjustment pin further comprises a through hole, a first end of the through hole is located in the first chamber, a second end of the through hole is located outside the first motor, and the first chamber is connected to an outside of the first motor through the through hole.
