DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0027] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0028] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] At present, some models of two-wheeled electric vehicles are equipped with fixed mud guards, but due to the large welding error of the rear section of the vehicle body and the large differences in mud guards, it is difficult to achieve platform universality. When two-wheeled electric vehicles are updated, the rear wheel mud guards that constitute each model cannot be universalized, which easily leads to a backlog of old mud guards. In response to the above problems, the embodiments of the present application provide the following technical solutions to adapt to the configuration requirements of different models and improve the applicability of the product.

[0030] Please refer to Figure 1 and Figure 2The present embodiment provides an adjustable rear wheel mudguard 100, including a first adjusting assembly 120 and a second adjusting assembly 130 for connecting to a rear fork 110, wherein the first adjusting assembly 120 includes a first swing arm 122 and a second swing arm 124 which are rotatably connected, and the second adjusting assembly 130 includes a rotating bracket 132 and an adjusting member 134 arranged on the rotating bracket 132, wherein 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 a rear wheel mudguard 140 arranged on the rotating bracket 132 rotates relative to the rear fork 110.

[0031] Specifically, when the first adjustment assembly 120 is connected to the rotating bracket 132 of the rear fork 110, when the first swing arm 122 and the second swing arm 124 rotate relative to each other, the angle between the first swing arm 122 and the second swing arm 124 increases or decreases. During the change of the angle between the first swing arm 122 and the second swing arm 124, the distance between the first swing arm 122 and the second swing arm 124 and the end that rotates relative to each other also increases or decreases. At this time, the rotating bracket 132 connected to the second swing arm 124 is driven to rotate, that is, to swing relative to the rear fork 110, so as to achieve the purpose of adjusting the rear wheel mud shoe 140 on the rotating bracket 132.

[0032] When the first swing arm 122 and the second swing arm 124 rotate relative to each other, a force needs to be applied to the second swing arm 124. By providing an adjusting member 134 on the rotating bracket 132 and connecting the adjusting member 134 to the second swing arm 124, the second swing arm 124 can be driven by the adjusting member 134, thereby changing the angle between the first swing arm 122 and the second swing arm 124. When the first swing arm 122 and the second swing arm 124 move, the rotating bracket 132 is driven to swing.

[0033] In actual applications, the postures of the first adjustment component 120 and the second adjustment component 130 can be adjusted according to the actual vehicle model and installation conditions, thereby adjusting the relative position of the rear wheel mud shoe 140 to meet the adaptation of different vehicle models. For example, according to different installation methods of the rear fork 110, 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 adjustment member 134 to match the current vehicle model. When the angle between the rear fork 110 and the horizontal plane is large, the angle between the first swing arm 122 and the second swing arm 124 is reduced by the adjustment component to match the current vehicle model.

[0034] The adjustable rear wheel mud shoe 100 provided in the embodiment of the present application is provided with a first adjustment component 120 and a second adjustment component 130 connected to the rear flat fork 110, so as to adjust the rear wheel mud shoe 140 through the cooperation of the first adjustment component 120 and the second adjustment component 130. During adjustment, the first swing arm 122 and the second swing arm 124 connected are rotated, and when the angle between the first swing arm 122 and the second swing arm 124 changes, the rotating bracket 132 is driven to swing relative to the rear flat fork 110. Among them, the driving force for changing the angle between the first swing arm 122 and the second swing arm 124 can be driven by the adjustment member 134 provided on the rotating bracket 132. In the above form, the adjustment member 134 can drive the rotating bracket 132 to swing relative to the rear flat fork 110 through the second swing arm 124, so that the rear wheel mud shoe 140 provided on the rotating bracket 132 rotates relative to the rear flat fork 110, thereby adapting to the configuration requirements of different vehicle models and improving the applicability of the product.

[0035] like Figure 1 and Figure 3 As shown, the first adjustment assembly 120 includes a first articulated seat 126 for being set on the rear fork 110, one end of the first swing arm 122 is connected to the first articulated seat 126, and the other end is connected to the second swing arm 124, so that the first swing arm 122 can rotate relative to the first articulated seat 126 and the second swing arm 124 respectively.

[0036] Specifically, the first articulated seat 126 and the rear fork 110 can be connected in the form of welding. The first articulated seat 126 includes a mounting seat connected to the rear fork 110 and a rotating shaft arranged on the mounting seat. One end of the first swing arm 122 is hinged to the first articulated seat 126 through the rotating shaft, and the other end is connected to the second swing arm 124. In this way, when the first swing arm 122 and the second swing arm 124 rotate relative to each other, the first swing arm 122 can also rotate relative to the rear fork 110 through the first articulated seat 126, thereby avoiding the first adjustable component 120 from being stuck when it is in motion, which is conducive to improving the stability during use.

[0037] Please continue to refer to Figure 1 and Figure 3 The second adjustment assembly 130 includes a second articulated seat 136 for being set on the rear fork 110, and there is a preset distance between the second articulated seat 136 and the first articulated seat 126. The rotating bracket 132 includes a main arm 1322 rotatably connected to the second articulated seat 136, and a first support arm 1324 and a second support arm 1326 respectively connected to the main arm 1322. The first support arm 1324 and the second support arm 1326 are respectively connected to the rear wheel mudguard 140.

[0038] Specifically, the second articulated seat 136 and the rear fork 110 can be connected in the form of welding. The second articulated seat 136 includes a mounting seat connected to the rear fork 110 and a rotating shaft arranged on the mounting seat, so that the main arm 1322 is rotatably connected to the second articulated seat 136 through the rotating shaft, that is, the rotating bracket 132 is rotatably connected to the rear fork 110 through the second articulated seat 136. In addition, by setting a preset distance between the second articulated seat 136 and the first articulated seat 126, it is helpful to ensure that there is enough adjustment space between the first adjustment assembly 120 and the second adjustment assembly 130, and at the same time, it is avoided that the force on the rear fork 110 is too concentrated, which is helpful to ensure that when the first articulated seat 126 and the second articulated seat 136 are respectively connected to the rear fork 110, they have stability and reliability of connection. By means of the first support arm 1324 and the second support arm 1326 connected to the main arm 1322, the desired connection relationship can be established between the rear fork 110 and the rear wheel mudguard 140 by rotating the bracket 132, which is beneficial to simplify the setting form and ensure the stability of the connection.

[0039] In an optional embodiment of the present application, the first arm 1324 and the second arm 1326 are arranged at a preset angle, and a bending structure is provided on the first arm 1324 and the second arm 1326 respectively.

[0040] Specifically, by forming a preset angle between the first arm 1324 and the second arm 1326, when the first arm 1324 and the second arm 1326 are connected to the rear wheel mud tile 140, they can be connected to two places of the rear wheel mud tile 140 that are far apart, thereby avoiding the rear wheel mud tile 140 from having poor stability due to the concentrated connection points. The above connection form is conducive to preventing the rear wheel mud tile 140 from deforming, and at the same time, a triangular stable support is formed at the connection between the first arm 1324, the second arm 1326 and the rear wheel mud tile 140, which is conducive to ensuring a stable connection. At the same time, by providing a bending structure on the first arm 1324 and the second arm 1326, respectively, it is conducive to improving the self-strength of the first arm 1324 and the second arm 1326, and preventing the first arm 1324 and the second arm 1326 from deforming themselves.

[0041] It should be noted that the rear fork 110 includes a left fork and a right fork that are relatively arranged. The first adjustment component 120 and the second adjustment component 130 are arranged on both the left fork and the right fork to ensure the balance of force. The embodiment of the present application is explained by one side.

[0042] like Figure 4 As shown, in an optional embodiment of the present application, the adjusting member 134 is an adjusting column, the rotating bracket 132 is provided with an adjusting nut 138 that cooperates with the adjusting column, and the second swing arm 124 is provided with a connecting seat 128 that cooperates with one end of the adjusting column.

[0043] Specifically, the outer ring of the adjustment column is provided with a thread that cooperates with the adjustment nut 138. For example, the adjustment column can directly adopt a bolt. When the adjustment column rotates relative to the adjustment nut 138, the end of the adjustment column facing the second swing arm 124 can approach or move away, so that the second swing arm 124 is driven to rotate relative to the first swing arm 122. It can be understood that in the process of driving the second swing arm 124 to rotate by the force of the adjustment column, the relative position relationship between the second swing arm 124 and the adjustment column changes. In order to prevent the occurrence of a stuck phenomenon during the action, the connecting seat 128 can be set to a rotatable form, such as a joint bearing. The adjustment nut 138 and the rotating bracket 132 can also be set to a rotating form, both of which can ensure stability during the action.

[0044] For example, when the connecting seat 128 and the second swing arm 124 are relatively fixed, a limiting groove is set on the connecting seat 128, the adjusting nut 138 is rotatably connected to the rotating bracket 132, and one end of the adjusting column is clamped in the limiting groove and can rotate relative to the limiting groove.

[0045] Specifically, the embodiment of the present application does not impose any specific restrictions on the setting form of the limit groove, as long as it can ensure that the connection seat 128 can be matched simply and the connection is stable. For example, the cross-section of the limit groove can be circular, and an opening can be set on the side of the connection seat 128 facing the adjustment column to facilitate the connection with the adjustment column. At this time, a ball-type limiter needs to be set on the end of the adjustment column facing the connection seat 128 to facilitate the adaptation with the connection seat 128. It can be understood that the cross-section of the limit groove can also be rectangular, and an opening can be set on the side of the connection seat 128 facing the adjustment column to facilitate the connection with the adjustment column. At this time, the end of the adjustment column facing the connection seat 128 only needs to be circumferentially cut with a notch, and the desired connection relationship can also be achieved.

[0046] In an optional embodiment of the present application, the adjusting nut 138 includes an adjusting part and a rotating part that are interconnected, the adjusting part is threadedly connected to the adjusting column, the rotating part is rotatably connected to the rotating bracket 132, and a fastening nut is also provided on the adjusting column, and the fastening nut is used to resist the adjusting part.

[0047] Specifically, the adjusting nut 138 can adopt the structure of a stepped shaft, and drill and tap the side of the shaft (i.e., set a threaded hole on the adjusting portion) to form a threaded hole that matches the adjusting column, and the rotating bracket 132 is provided with a positioning hole that matches the adjusting nut 138, so that the adjusting nut 138 can be inserted into the positioning hole (and the rotating portion can be matched with the rotating bracket 132) and rotatably connected with the rotating bracket 132. In addition, by setting a fastening nut on the adjusting column, after adjusting the adjusting column and the adjusting nut 138 to a suitable position, in order to ensure the stability of the current state, the fastening nut can be used to tighten, and form a double nut matching form with the adjusting nut 138, thereby ensuring that the threaded connection maintains the stability of the current state.

[0048] like Figure 5 As shown, when the rotating part cooperates with the rotating bracket 132 , a circular slot is provided on the rotating part, and a retaining spring 139 cooperating with the rotating bracket 132 is provided on the circular slot to enable the rotating part to be rotatably connected with the rotating bracket 132 .

[0049] By adopting the above-mentioned form, the cooperation between the rotating part and the rotating bracket 132 can achieve the required connection relationship by using only one retaining spring 139. While avoiding axial movement of the rotating part relative to the rotating bracket 132, it can also ensure the rotational connection between the rotating part and the rotating bracket 132, which is conducive to simplifying the setting form and ensuring the reliability of the connection.

[0050] In an optional embodiment of the present application, the adjustment member 134 is a linear motor or a linear push rod, and the output end of the linear motor or the linear push rod is connected to the second swing arm 124 through a joint bearing so that the second swing arm 124 is driven to rotate relative to the first swing arm 122.

[0051] By adopting the above form, the second swing arm 124 can also be driven to achieve the purpose of adjusting the first adjustment component 120 and the second adjustment component 130. During adjustment, it is only necessary to determine the required extension or retraction length through the linear motor or the linear push rod. This is conducive to realizing intelligent adjustment. After the adjustment is completed, the current state of the linear motor or the linear push rod can be locked.

[0052] The present application also discloses a two-wheeled electric vehicle, including the adjustable rear wheel mud tile 100 in the above embodiment. The two-wheeled electric vehicle includes the same structure and beneficial effects as the adjustable rear wheel mud tile 100 in the above embodiment. The structure and beneficial effects of the adjustable rear wheel mud tile 100 have been described in detail in the above embodiment, and will not be repeated here.

[0053] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
