TECHNICAL FIELD

[0001] The present application relates to the technical field of scooters, and in particular to a frame assembly and a scooter. BACKGROUND

[0002] At present, a scooter includes a front wheel, a rear wheel, a front frame, a pedal frame, a controller and a battery. The front wheel is connected to the front frame. The rear wheel is connected to one end of the pedal frame. The other end of the pedal frame is fixedly connected to the front frame. The pedal frame has a receiving cavity. The controller and the battery are arranged inside the receiving cavity. However, the controller and the battery are arranged side by side along the length direction of the scooter. The controller occupies the length direction space of the scooter, resulting in a more compact structure in the length direction. SUMMARY

[0003] Embodiments of the present application provide a frame assembly and a scooter to solve the problem that the controller occupies the length direction space of the scooter, resulting in a more compact structure in the length direction in the related art.

[0004] In a first aspect, the present application provides a frame assembly, which comprises:

[0005] a frame having a cavity;

[0006] a rear wheel located partially inside the cavity and rotationally connected to the frame;

[0007] a controller mounted to the inner side wall of the cavity along the width direction of the frame assembly.

[0008] The frame assembly provided by the embodiments of the present application has the following beneficial effects. The controller is arranged in the cavity for arranging the rear wheel, and the controller is mounted to the inner side wall of the cavity. The length direction space of the controller and the frame assembly is decoupled, so that the length direction space of the controller and the scooter is decoupled. Therefore, the controller does not affect the length direction space of the scooter, and the structure in the length direction of the scooter can be loose. In addition, the length of the whole scooter can be avoided, so that the length of the whole scooter is small.

[0009] In a possible implementation, the cavity includes a first side wall, a second side wall and a third side wall. The third side wall connects the first side wall and the second side wall. Along the length direction of the frame assembly, the third side wall and the rear wheel are arranged side by side and spaced apart. Along the width direction of the frame assembly, the rear wheel is located between the first side wall and the second side wall, and the controller is located between the first side wall and the rear wheel. In this way, the controller is arranged between the first side wall and the rear wheel, avoiding the controller occupying the length direction space of the frame assembly, which helps to loosen the structure in the length direction of the frame assembly, so that the structure in the length direction of the scooter is loose. The length of the frame assembly can also be reduced, so that the length of the scooter is reduced.

[0010] In a possible implementation, the frame assembly further comprises a rear wheel shaft, the rear wheel is rotatably connected to the frame through the rear wheel shaft, and the controller is located between the rear wheel shaft and the third side wall. In this way, the controller is arranged in a space surrounded by the rear wheel, the first side wall, the third side wall and the rear wheel shaft, avoiding the controller occupying the length direction space of the scooter, and also avoiding the length of the frame increasing to make the length of the whole vehicle smaller.

[0011] In a possible implementation, the first side of the controller is attached to the first side wall, and / or the second side of the controller is attached to the third side wall.

In this way, the control cable is arranged apart from the rear wheel, the control cable is decoupled from the rear wheel, and the connection between the controller and the components in the frame is realized through the control cable.

[0013] In a possible implementation, the controller is a cuboid, and the length direction of the controller is parallel to the length direction of the frame assembly. In this way, the influence of the controller on the width of the whole vehicle can be reduced, which is helpful for reducing the width of the whole vehicle.

[0014] In a possible implementation, the frame assembly further comprises a charging port structure, and the charging port structure is arranged on the second side wall. In this way, the controller and the charging port structure are arranged on the first side wall and the second side wall respectively, which can reduce the occupation of the internal space of the frame and is helpful for increasing the capacity of the battery in the frame. Wiring can also be facilitated.

[0015] In a possible implementation, the third side wall has a wiring hole, and the controller and / or the charging port structure are connected to components in the frame through the wiring hole. In this way, the controller and the charging port structure are connected to the components in the frame, for example, a power cable is connected to a battery in the frame through the wiring hole, and a control cable is electrically connected to a circuit board in the frame.

[0016] In a possible implementation, the frame assembly further comprises a protection plate and a control cable, the protection plate is fixedly connected to the frame and cooperates with the inner wall of the cavity to form an accommodation space, and the controller and / or the control cable are located inside the accommodation space. In this way, dust, stones and other foreign matters in the outside world can be prevented from entering or impacting the controller, and damage to the controller can be prevented. In addition, the protection plate can also protect the control cable and prevent the control cable from being damaged.

[0017] In a possible implementation, the protection plate includes a first wall plate part and a second wall plate part, the first wall plate part is arranged side by side with the third side wall along the length direction of the frame assembly, and the second wall plate part is arranged side by side with the first side wall along the width direction of the frame assembly. In this way, the protection plate can protect the controller and / or the control cable.

[0018] In a possible implementation, the cavity includes a top wall, which is located on one side of the controller along the height direction of the frame assembly and is fixedly connected with at least one of the controller and the protection plate. In this way, the controller and / or the protection plate are fixed by the top wall, which can reduce the difficulty of connecting the frame with the controller and / or the protection plate, and help to improve the assembly efficiency of the scooter.

[0019] In a possible implementation, the protection plate includes a protection body and a connecting lug, the protection body encloses the accommodation space with the inner wall of the cavity, and the connecting lug is fixedly connected with the top wall. In this way, the connecting lug is fixedly connected with the top wall, and the top wall is fixedly connected with the protection plate.

[0020] In a possible implementation, the controller and the rear wheel are arranged at intervals in the width direction of the frame assembly. In this way, the controller can avoid interfering with the rotation of the rear wheel, and the safety of the controller can be ensured.

[0052] The terms used in the embodiments of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application, and the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0053] Figure 1 A structural schematic diagram of a scooter provided by the embodiments of the present application.

[0054] The embodiments of the present application provide a scooter, which can also be referred to as an electric scooter. In addition, the scooter can be a two-wheeled scooter, a three-wheeled scooter, etc., and the following description takes the scooter as a two-wheeled scooter as an example.

[0055] In the embodiments of the present application, the scooter includes a frame assembly, a front wheel 400, a handle 500, and a rear baffle assembly 800. As shown in Figure 1 the frame assembly includes a rear wheel 300 and a frame 100, the frame 100 includes a front frame 120 and a pedal frame 110, the pedal frame 110 has a substantially flat surface for a user to stand on, one end of the pedal frame 110 is connected to the front frame 120 along the length direction X of the frame assembly, and the other end of the pedal frame 110 is rotatably connected with the rear wheel 300. The top end of the front frame 120 is connected with the handle 500 along the height direction Z of the frame assembly, and the bottom end of the front frame 120 is rotatably connected with the front wheel 400.

[0056] In the embodiments of the present application, the length direction of the scooter is defined as the length direction X of the frame assembly, the width direction of the scooter is defined as the width direction Y of the frame assembly, and the height direction of the scooter is defined as the height direction Z of the frame assembly.

[0057] Figure 2 For Figure 1 the rear baffle assembly in FIG. 8B is a perspective view of the three-dimensional structure of the rear baffle, Figure 3 for Figure 2 the rear baffle in FIG. 8B is a perspective view of the three-dimensional structure of the rear baffle.

[0058] As Figure 2 shown in FIG. 8B, the rear baffle assembly 800 includes a rear baffle 810 and a cover plate 820. As Figure 3 shown in FIG. 8B, the rear baffle 810 includes a connecting plate portion 811 and a baffle portion 812, the baffle portion 812 forms a baffle groove accommodating the rear wheel 300, and the connecting plate portion 811 is fixedly connected with the pedal bracket 110, for example, the connecting plate portion 811 is threadedly connected with the pedal bracket 110 by screws. The cover plate 820 covers the top surface of the connecting plate portion 811 and is connected with the connecting plate portion 811, and the cover plate 820 is used to shield the through holes on the connecting plate portion 811 and the screws connecting the rear baffle 810 with the pedal bracket 110, so as to improve the appearance of the scooter.

[0059] In some embodiments, the cover plate 820 can be fixedly connected with the connecting plate portion 811 by adhesion, clamping or the like.

[0060] The scooter further includes a controller 200 and a battery, the battery is used to power the scooter, and the controller 200 is used to control the functions of charging, discharging and driving of the scooter.

[0061] In the related art, the pedal bracket has an accommodating cavity, and the controller and the battery are arranged inside the accommodating cavity and arranged side by side along the length direction of the scooter. However, when the controller is installed inside the accommodating cavity, the controller will occupy the length space of the scooter, resulting in a more compact structure in the length direction. In addition, when the overall length of the scooter is constant, after the controller occupies a part of the accommodating cavity, the remaining part of the accommodating cavity has a smaller length, resulting in a smaller length of the battery and a smaller capacity of the battery, which is difficult to improve the endurance of the scooter. In addition, the controller occupies the length direction space of the scooter, which also results in a longer overall length of the scooter.

[0062] Figure 4 For Figure 1 the scooter in FIG. 1 is an exploded view of the scooter, Figure 5 for Figure 1 the scooter in FIG. 1 is a first partial structure view of the scooter, Figure 6 for Figure 1 the scooter in FIG. 1 is a second partial structure view of the scooter, Figure 7 for Figure 4a first partial view of the pedal frame member in the vehicle frame assembly, Figure 8 for Figure 4 a second partial view of the pedal frame member in the vehicle frame assembly.

[0063] Therefore, in the embodiments of the present application, the pedal frame member 110 of the vehicle frame 100 has a cavity 130 (as shown in Figure 4 , part of the rear wheel 300 is located inside the cavity 130 (as shown in Figure 5 or Figure 6 , the rear wheel 300 is rotationally connected to the pedal frame member 110 of the vehicle frame 100, the controller 200 is located inside the cavity 130 and is spaced apart from the rear wheel 300, the controller 200 is mounted to the inner side wall of the cavity 130 along the width direction Y of the vehicle frame assembly, the controller 200 is spaced apart from the rear wheel 300 in the width direction Y of the vehicle frame assembly, that is, the controller 200 is located on one side of the rear wheel 300 along the width direction Y of the vehicle frame assembly.

[0064] In this way, the controller 200 is arranged in the cavity 130 of the vehicle frame 100 for arranging the rear wheel 300, and the controller 200 is located on one side of the rear wheel 300, the controller 200 is spatially decoupled from the length direction of the vehicle frame assembly, the controller 200 does not occupy the length direction space of the vehicle frame assembly, and the length direction structure can be loose. In addition, it does not affect the overall length of the scooter, so that the overall length of the scooter is smaller. In addition, when the length of the scooter is constant, arranging the controller 200 outside the accommodating cavity of the pedal frame member 110 can increase the length of the battery, thereby improving the battery capacity and further improving the endurance of the scooter.

[0065] It can be understood that, in combination with Figure 7 and Figure 8 , the cavity 130 is a gap that penetrates the pedal frame member 110 along the height direction Z of the vehicle frame assembly, so that the rear wheel 300 can be rotationally connected to the pedal frame member 110, and helps to reduce the overall length of the scooter.

[0066] Specifically, as shown in Figure 5 , the pedal frame member 110 includes a body portion 111, a first branch portion 112, and a second branch portion 113. The body portion 111 has an accommodating cavity for accommodating components such as a battery and a circuit board, one end of the body portion 111 is connected to the front frame 120, and the other end of the body portion 111 is fixedly connected to the first branch portion 112 and the second branch portion 113, respectively. The first branch portion 112 and the second branch portion 113 are spaced apart along the width direction Y of the vehicle frame assembly, the first branch portion 112, the second branch portion 113, and the body portion 111 together form the cavity 130, the opposite ends of the rear wheel 300 are rotationally connected to the first branch portion 112 and the second branch portion 113, respectively, and the controller 200 is fixedly connected to the first branch portion 112.

[0067] Exemplarily, as shown in Figure 4 The frame assembly further includes a rear wheel shaft 310, both ends of the rear wheel shaft 310 are rotatably connected with the first branch 112 and the second branch 113 respectively, and the rear wheel 300 is sleeved on the rear wheel shaft 310 and rotatably connected with the frame 100 through the rear wheel shaft 310.

[0068] Exemplarily, as shown in Figure 4 The rear wheel 300 includes a hub 320 and a tire 330. The hub 320 is sleeved on the rear wheel shaft 310 and connected with the rear wheel shaft 310, and the tire 330 is sleeved on the hub 320.

[0069] In combination with Figure 7 and Figure 8 It can be seen that the cavity 130 includes a first side wall 131, a second side wall 132 and a third side wall 133. The third side wall 133 connects the first side wall 131 and the second side wall 132, and the first side wall 131 and the second side wall 132 are located on the same side of the third side wall 133, so that the side wall of the cavity 130 is a U-shaped side wall. Along the length direction X of the frame assembly, the third side wall 133 and the rear wheel 300 are arranged side by side and spaced apart.

[0070] In some embodiments, along the width direction Y of the frame assembly, the rear wheel 300 is located between the first side wall 131 and the second side wall 132, and the controller 200 is located between the first side wall 131 and the rear wheel 300. Arranging the controller 200 between the first side wall 131 and the rear wheel 300 avoids occupying the length direction space of the frame assembly, which helps to loosen the length direction structure of the frame assembly, so as to loosen the length direction structure of the scooter. In addition, the length of the frame assembly can be reduced, thereby reducing the length of the scooter.

[0071] In some embodiments, as shown in Figure 9 Along the length direction X of the frame assembly, the controller 200 is located between the rear wheel shaft 310 and the third side wall 133. In this way, the controller 200 is arranged in the space surrounded by the rear wheel 300, the first side wall 131, the third side wall 133 and the rear wheel shaft 310, which avoids occupying the length direction space of the frame assembly, and also avoids increasing the length of the frame 100 to make the overall length smaller.

[0072] In order to realize the rotatable connection between the frame 100 and the rear wheel 300, exemplarily, the first side wall 131 and the second side wall 132 each have a rotating hole, and both ends of the rear wheel shaft 310 are inserted into the rotating holes on the first side wall 131 and the second side wall 132 respectively, so as to realize the rotatable connection between the first branch 112 and the second branch 113 and the rear wheel 300 respectively.

[0073] Figure 9 For Figure 1a third partial view of the scooter in FIG. 1, Figure 10 is Figure 1 a fourth partial view of the scooter in FIG. 1.

[0074] In some possible implementations, in combination with Figure 9 and Figure 10 It can be known that the first side of the controller 200 is attached to the first side wall 131, that is, the first side of the controller 200 is in contact with the first side wall 131, or in other words, the gap between the first side wall 131 and the controller 200 in the width direction Y of the frame assembly is equal to zero. In this way, the influence of the controller 200 on the overall vehicle width can be reduced, which helps to reduce the width of the scooter and achieve miniaturized design of the scooter.

[0075] Of course, in addition to being attached to the first side wall 131, in some embodiments, the first side wall 131 and the controller 200 can also be spaced apart in the width direction Y of the frame assembly, that is, the controller 200 is not in contact with the first side wall 131.

[0076] In some possible implementations, as shown in Figure 10 the second side of the controller 200 is attached to the third side wall 133, that is, the minimum gap between the controller 200 and the third side wall 133 in the length direction X of the frame assembly is zero. In this way, the influence of the controller 200 on the overall vehicle length can be reduced, which helps to reduce the length of the scooter and achieve miniaturized design of the scooter.

[0077] Of course, in addition to being attached to the third side wall 133, in some embodiments, the third side wall 133 and the controller 200 can also be spaced apart in the length direction X of the frame assembly, that is, the controller 200 is not in contact with the third side wall 133.

[0078] In some possible implementations, as shown in Figure 10 the controller 200 is a cuboid, and the length direction of the controller 200 is parallel to the length direction X of the frame assembly. Specifically, the length of the controller 200 is greater than the width of the controller 200, the width of the controller 200 is greater than the thickness of the controller 200, the length direction of the controller 200 is parallel to the length direction X of the frame assembly, the width direction of the controller 200 is parallel to the height direction Z of the frame assembly, and the thickness direction of the controller 200 is parallel to the width direction Y of the frame assembly. In this way, the influence of the controller 200 on the width of the scooter is small, which helps to reduce the width of the scooter.

[0079] In some possible implementations, as shown in Figure 10As shown, the controller 200 is connected with a control cable 900, the control cable 900 extends along the third side wall 133 and is used to connect with components in the frame 100, for example, the control cable 900 is connected with a circuit board in the frame 100. Since the control cable 900 is fixedly connected with the third side wall 133, the control cable 900 is spaced apart from the rear wheel 300, the control cable 900 is decoupled from the rear wheel 300, and the control cable 900 does not affect the rotation of the rear wheel 300. In addition, the control cable 900 realizes the electrical connection between the controller 200 and the components in the frame 100.

[0080] The number of control cables 900 is not limited here. Exemplarily, as shown in Figure 10 the number of control cables 900 is multiple, and the multiple control cables 900 are arranged side by side along the height direction Z of the frame assembly.

[0081] Exemplarily, the control cable 900 can be fixedly connected with the third side wall 133 by adhesion, clamping or the like.

[0082] In some possible implementations, as shown in Figure 10 the cavity 130 includes a top wall 134, which is located on one side of the controller 200 and fixedly connected with the controller 200 along the height direction Z of the frame assembly, and is spaced apart from the rear wheel 300. In this way, the difficulty of connecting the controller 200 with the frame 100 can be reduced, and the assembly efficiency of the scooter can be improved.

[0083] Exemplarily, the top wall 134 can have a fixing hole for a fastener to pass through, and the fastener is fixedly connected with the housing of the controller 200 to realize the fixed connection between the controller 200 and the top wall 134.

[0084] In some embodiments, the fastener can be a screw or a bolt, which is screwed with the housing of the controller 200 after passing through the fixing hole, to realize the fixed connection between the controller 200 and the frame 100.

[0085] In some embodiments, the top wall 134 and one of the first side wall 131, the second side wall 132 and the third side wall 133 are an integral structure integrally formed, and are fixedly connected with the other two side walls, for example, the top wall 134 and the third side wall 133 are an integral structure integrally formed, and the top wall 134 is respectively welded with the first side wall 131 and the second side wall 132. In this way, the connection firmness of the top wall 134 and the side walls of the cavity 130 can be improved, and the assembly difficulty of the frame 100 can be reduced, and the production efficiency of the frame 100 can be improved.

[0086] Figure 11 For Figure 1 the cross-sectional view of the scooter is shown.

[0087] In some possible implementation manners, as shown in Figure 4 The scooter frame assembly can further include a protective plate 600. The protective plate 600 is fixedly connected with the frame 100, and the protective plate 600 is arranged in a spaced manner with the rear wheel 300 (as shown in Figure 5 At least part of the protective plate 600 is located inside the cavity 130, for example, as shown in Figure 5 and Figure 6 The protective plate 600 is located inside the cavity 130. As shown in Figure 11 The protective plate 600 and the inner wall of the cavity 130 jointly form an accommodation space, and the controller 200 is located inside the accommodation space.

[0088] In this way, it is possible to avoid that foreign matters such as dust and stones from the outside enter or impact the controller 200, and avoid damage to the controller 200. In addition, the protective plate 600 can be fixedly connected with the controller 200, and the controller 200 is installed on the frame 100, that is, the controller 200 is fixedly connected with the frame 100 through the protective plate 600.

[0089] Figure 12 FIG. 6 is a schematic view of the protective plate in Figure 5 .

[0090] For example, as shown in Figure 11 and Figure 12 The protective plate 600 includes a first wall plate portion 630 and a second wall plate portion 640. The first wall plate portion 630 is arranged in a side-by-side manner with the third side wall 133 along the length direction X of the scooter frame assembly, and the second wall plate portion 640 is arranged in a side-by-side manner with the first side wall 131 along the width direction Y of the scooter frame assembly. As shown in Figure 5 The first wall plate portion 630 is arranged in a side-by-side and spaced manner with the rear wheel 300 along the length direction X of the scooter frame assembly, and the second wall plate portion 640 is arranged in a side-by-side and spaced manner with the rear wheel 300 along the width direction Y of the scooter frame assembly. Therefore, the protective plate 600 has a structure similar to an L-shaped plate structure, one side of which cooperates with the first side wall 131 and the other side of which cooperates with the third side wall 133, so as to protect the controller 200 and the control cable 900.

[0091] Figure 13 FIG. 5 is a fifth partial schematic view of the scooter in Figure 1 .

[0092] In some possible implementation manners, as shown in Figure 13 The protective plate 600 is located on one side of the top wall 134 along the height direction Z of the scooter frame assembly, and the protective plate 600 is fixedly connected with the top wall 134. In this way, it is convenient to fixedly connect the frame 100 with the protective plate 600, reduce the assembly difficulty of the frame 100 and the protective plate 600, and improve the assembly efficiency of the scooter.

[0093] Of course, in addition to being located on one side of the top wall 134, in some embodiments the protective plate 600 has a protective groove, and the top wall 134 may also be located inside the protective groove, with the protective groove and the frame 100 forming an accommodating space.
