At present, fixed mud blocking parts are additionally arranged on two-wheeled electric vehicles of partial vehicle types, but the mud blocking parts have large differences due to large welding errors of the rear sections of the vehicle bodies, so that the platform is difficult to realize universality. When the two-wheeled electric motor car is updated, the rear wheel fender mud part that constitutes every model of motorcycle type can't reach the universalization, causes the stock overstock of old money fender mud part easily. To the above problem, the embodiment of the present application provides the following technical solutions to adapt to configuration requirements of different vehicle types, and improve the applicability of products.

Referring to fig. 1 and 2, the present embodiment provides an adjustable rear wheel mudguard 100, which includes a first adjusting assembly 120 and a second adjusting assembly 130 connected to a rear fork 110, where the first adjusting assembly 120 includes a first swing arm 122 and a second swing arm 124 rotatably connected to each other, the second adjusting assembly 130 includes a rotating bracket 132 and an adjusting member 134 disposed on the rotating bracket 132, the second swing arm 124 is respectively connected to the rotating bracket 132 and the adjusting member 134, and the adjusting member 134 drives the rotating bracket 132 to swing relative to the rear fork 110 through the second swing arm 124, so that the rear wheel mudguard 140 disposed on the rotating bracket 132 rotates relative to the rear fork 110.

Specifically, under the condition that the first adjusting assembly 120 is respectively connected with the rotary bracket 132 of the rear fork 110, when the first swing arm 122 and the second swing arm 124 rotate relatively, the included angle between the first swing arm 122 and the second swing arm 124 is increased or decreased. In the process of changing the angle between the first swing arm 122 and the second swing arm 124, the distance between the ends of the first swing arm 122 and the second swing arm 124, which are far away from the relative rotation, is also increasing or decreasing. At this time, the rotating bracket 132 connected to the second swing arm 124 is driven to rotate, i.e. swing relative to the rear fork 110, so as to adjust the rear wheel mudguard 140 on the rotating bracket 132.

When the first swing arm 122 and the second swing arm 124 rotate relatively, an acting force needs to be applied to the second swing arm 124, the adjusting piece 134 is arranged on the rotating bracket 132, and the adjusting piece 134 is connected with the second swing arm 124, so that the second swing arm 124 is driven through the adjusting piece 134, the size of an angle between the first swing arm 122 and the second swing arm 124 is changed, and the rotating bracket 132 is driven to swing when the first swing arm 122 and the second swing arm 124 move.

In practical application, the postures of the first adjusting assembly 120 and the second adjusting assembly 130 can be adjusted according to actual vehicle models and installation conditions, so that the relative position of the rear wheel mud tile 140 can be adjusted to meet the adaptation of different vehicle models. Illustratively, when the angle between the rear fork 110 and the horizontal plane is small, the angle between the first swing arm 122 and the second swing arm 124 is increased by the adjusting member 134 to match the current vehicle type, according to the way the rear fork 110 is installed. When the included angle between the rear bottom fork 110 and the horizontal plane is large, the included angle between the first swing arm 122 and the second swing arm 124 is reduced through the adjusting assembly, and the included angle is matched with the current vehicle type.

The adjustable rear wheel mudguard 100 provided by the embodiment of the application is provided with the first adjusting component 120 and the second adjusting component 130 which are used for being connected with the rear fork 110, so that the adjustment of the rear wheel mudguard 140 is realized through the cooperation of the first adjusting component 120 and the second adjusting component 130. During adjustment, the first swing arm 122 and the second swing arm 124 are rotated to swing the rotary bracket 132 relative to the rear fork 110 when the angle between the first swing arm 122 and the second swing arm 124 is changed. Wherein the driving force for changing the angle between the first swing arm 122 and the second swing arm 124 can be driven by the adjusting member 134 provided on the rotating bracket 132. By adopting the above form, the adjusting piece 134 can drive the rotating bracket 132 to swing relative to the rear bottom fork 110 through the second swing arm 124, so that the rear wheel clay tile 140 arranged on the rotating bracket 132 rotates relative to the rear bottom fork 110, thereby adapting to the configuration requirements of different vehicle types and improving the applicability of products.

As shown in fig. 1 and 3, the first adjusting assembly 120 includes a first hinge base 126 for being disposed on the rear fork 110, and one end of the first swing arm 122 is connected to the first hinge base 126, and the other end is connected to the second swing arm 124, so that the first swing arm 122 rotates relative to the first hinge base 126 and the second swing arm 124.

Specifically, the first hinge seat 126 and the rear fork 110 may be connected by welding, the first hinge seat 126 includes a mounting seat connected to the rear fork 110, and a rotating shaft disposed on the mounting seat, one end of the first swing arm 122 is hinged to the first hinge seat 126 through the rotating shaft, and the other end of the first swing arm is connected to the second swing arm 124. Thus, when the first swing arm 122 and the second swing arm 124 rotate relatively, the first swing arm 122 can also rotate relatively between the first hinge seat 126 and the rear fork 110, so as to avoid the jamming phenomenon when the first adjusting assembly 120 acts, which is beneficial to improving the stability during use.

It can be understood that, in the process of driving the second swing arm 124 to rotate by the acting force of the adjusting column, the relative position relationship between the second swing arm 124 and the adjusting column changes, and in order to prevent the locking phenomenon in the action process, the connecting seat 128 may be set to be rotatable, such as a knuckle bearing. The adjusting nut 138 and the rotating bracket 132 can also be arranged in a rotating mode, and both can ensure the stability during the action.

Illustratively, when the connecting base 128 and the second swing arm 124 are relatively fixed, a limiting groove is formed on the connecting base 128, the adjusting nut 138 is rotatably connected with the rotating bracket 132, and one end of the adjusting post is clamped in the limiting groove and can rotate relative to the limiting groove.

Specifically, this application embodiment does not do specific restriction to the form that sets up of spacing groove, as long as can guarantee between the connecting seat 128 that the cooperation is simple, and connect stably can. For example, the cross section of the limiting groove may be circular, and an opening is provided at one side of the connecting seat 128 facing the adjusting post for connection with the adjusting post, and at this time, the end of the adjusting post facing the connecting seat 128 needs to be provided with a ball-type limiting part for matching with the connecting seat 128. It will be appreciated that the cross-section of the retention slot may also be rectangular and an opening may be provided in the side of the attachment base 128 facing the adjustment post to facilitate attachment to the adjustment post. At this point, the end of the adjustment post facing the connection seat 128 need only be cut around a notch to achieve the desired connection.
