In an aspect of the embodiment of the present application, an electric vehicle rear leaning device is provided, as shown in fig. 1 to 6, including a connecting piece, a rear clothes hanger 110 and a backrest component 160, wherein the rear clothes hanger 110 may be connected to a frame body of the electric vehicle, the connecting manner may be a fixed connection such as welding, riveting, etc., and the backrest component 160 is rotationally connected to the rear clothes hanger 110, so that the backrest component 160 can have a base rotating relative to the rear clothes hanger 110, and of course, along with the rotation of the backrest component 160, the angle of the backrest component relative to the rear clothes hanger 110 will change. On this basis, the connecting piece has two states, namely a locking state and an unlocking state, namely when the connecting piece is in the locking state, the connecting piece can enable the backrest component 160 and the rear clothes hanger 110 to be relatively fixed, and at the moment, the backrest component 160 can not rotate relative to the rear clothes hanger 110, so that the backrest component 160 can provide better leaning strength, and a user or an object can lean conveniently. When the connecting piece is in the unlocking state, the relative fixation of the backrest component 160 and the rear clothes hanger 110 can be relieved, at the moment, the backrest component 160 can be pushed to rotate relative to the rear clothes hanger 110 by means of external force, then the included angle between the backrest component 160 and the rear clothes hanger 110 is adjusted, after the backrest component 160 is rotated to a proper position by a user, the unlocking state of the connecting piece can be switched to the locking state again, so that the backrest component 160 has better leaning intensity at the proper position, and therefore, the angle adjustment of the backrest component 160 relative to the rear clothes hanger 110 is realized, the user can conveniently find a leaning angle suitable for the user, the use comfort of the user is improved, meanwhile, the space in front of the backrest component 160 can be synchronously adjusted by the angle adjustment of the backrest component 160, the user with different shapes or the article with different volumes can be conveniently matched, and the use scene of the user can be effectively expanded.

Specifically, referring to fig. 1 and 2, the connecting member may be in a locked state, so that the backrest assembly 160 cannot rotate relative to the rear clothes hanger 110, so that the backrest assembly 160 can provide a better leaning strength in the position, and is convenient for a user to lean on, and meanwhile, when carrying an article, the connecting member can also provide a better limit for the article. When the user needs to adjust the angle, the connecting piece can be switched from the locking state to the unlocking state, in this state, the fixation of the backrest component 160 and the rear clothes hanger 110 can be released, the user can conveniently change the position of the backrest component 160 by pushing the backrest component 160 to rotate relative to the rear clothes hanger 110, and after the user adjusts the backrest component 160 to a proper position, the unlocking state of the connecting piece can be switched to the locking state, so that the backrest component 160 is fixed with the rear clothes hanger 110 again. In addition, when a user needs to transport a large article, the backrest assembly 160 can be adjusted to the position shown in fig. 4 by switching the connecting piece from the locking state to the unlocking state, namely, at the moment, the backrest assembly 160 is basically flush with the seat surface of the seat 101 of the electric vehicle, and then switching the unlocking state of the connecting piece to the locking state, so that the backrest assembly 160 is kept at the position, thereby effectively expanding the carrying capacity of the electric vehicle, enabling the carrying capacity of the electric vehicle to transport the large article, and enriching the use scenes of the backrest assembly 160.

Alternatively, as shown in fig. 5, the connection member includes a first tooth portion 210, a second tooth portion 220 and a driving portion 230, and as shown in fig. 1, a fixed shaft is fixedly disposed on the rear hanger 110, and the backrest module 160 is rotatably sleeved on the fixed shaft, the first tooth portion 210 is fixedly disposed on the fixed shaft, the second tooth portion 220 is fixedly disposed on the backrest module 160, and the driving portion 230 is in driving connection with the second tooth portion 220, so that, as shown in fig. 5 (a), when the connection member is in a locked state, the first tooth portion 210 and the second tooth portion 220 are engaged, and thus, the backrest module 160 cannot rotate relative to the rear hanger 110, thereby achieving the fixation of the backrest module 160 and the rear hanger 110 by the engagement of the first tooth portion 210 and the second tooth portion 220. When the connection member is required to be switched from the locked state to the unlocked state, as shown in fig. 5 (b), the user can push the second tooth part 220 to move along the axial direction of the fixed shaft via the driving part 230, so that the second tooth part 220 is separated from the first tooth part 210, and thus, the backrest module 160 can rotate relative to the rear clothes hanger 110, and after the user adjusts the backrest module to a proper position, the connection member can be switched from the unlocked state to the locked state again, i.e. the connection member is switched from fig. 5 (b) back to fig. 5 (a), so that the first tooth part 210 and the second tooth part 220 are engaged again at the proper position, thereby realizing the fixation of the backrest module 160 and the rear clothes hanger 110.

As shown in fig. 1, the extension portion 120 may be disposed on the fixed shaft, so that when the backrest module 160 is adjusted to the position shown in fig. 4, the backrest module 160 and the extension portion 120 may abut against each other, and the backrest module 160 is supported by the extension portion 120, thereby improving the load-bearing capacity of the backrest module 160.

Of course, the manner in which the connection member is switched from (b) in fig. 5 back to (a) in fig. 5 may be by the user pulling back the second tooth portion 220 via the driving portion 230 in a reverse direction so that the second tooth portion 220 and the first tooth portion 210 are re-engaged, or may be by the reset member 240, that is, the connection member further includes the reset member 240 connected to the second tooth portion 220, and the reset member 240 is used to provide a reset force to the second tooth portion 220 so that the second tooth portion 220 has a tendency to engage with the first tooth portion 210.
