Description

Technical Field

[0001] This utility model relates to the field of mobility scooter technology, and in particular to a two-wheeled vehicle. Background Technology

[0002] Two-wheeled vehicles are currently a widely used mode of transportation. They have advantages such as simple operation, high flexibility, and convenient maintenance, and can meet the needs of most people.

[0003] In related technologies, to ensure that shorter riders can place both feet on the ground when parking, the seat position of two-wheeled vehicles is usually lowered during the design process, and the bottom guard plate is lowered accordingly to match the battery capacity requirements. However, the method of lowering the lowest point of the vehicle in related technologies can easily affect the overall vehicle passability and is not conducive to riding for taller riders. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of this utility model propose a two-wheeled vehicle that allows the underbody protection plate to be within a safe height range from the ground to ensure the vehicle's passability.

[0006] A two-wheeled vehicle according to an embodiment of the present utility model includes a frame and a bottom guard plate. The bottom guard plate is disposed below the frame and includes a front side and a bottom surface connected to each other. The bottom surface is arranged inclined downward in a direction toward the front side and has a chamfer at the connection between the front side and the bottom surface.

[0007] According to the embodiments of the present invention, the two-wheeled vehicle has a bottom plate that slopes downwards towards the front side. Therefore, the lowest point of the vehicle body is formed at the junction of the front side and the bottom plate. By designing the junction as a chamfer, that is, by treating the junction with a flat or curved surface, the height of the junction relative to the ground can be effectively raised, thus raising the lowest point of the vehicle body and improving the overall vehicle passability. Therefore, compared with related technologies, the present invention can keep the bottom plate within a safe height range from the ground to ensure the overall vehicle passability.

[0008] In some embodiments, the bottom guard plate includes a transition surface connecting the front side and the bottom surface, the transition surface forming the chamfer, the transition surface extending in a top-to-bottom direction and inclined toward the bottom surface.

[0010] In some embodiments, the two-wheeled vehicle further includes a foot pedal disposed above the frame and comprising a front end, a foot pedal portion, and a rear end portion connected in sequence, the foot pedal portion extending toward the front end portion and arranged at a downward angle.

[0011] In some embodiments, the front end extends in an upward direction and is arranged at an angle to the front.

[0012] In some embodiments, on the projection plane formed in the vertical and horizontal directions, the projection of the footrest forms an angle α with the horizontal plane, and α is 5°-8°.

[0015] The front end of the upper tube extends from bottom to top and tilts forward.

[0016] In some embodiments, the upper tube includes a first tube segment connected to its front end, the first tube segment corresponding to the foot pedal, and the central axis of each of the first tube segment and the lower tube forms an angle γ with the horizontal plane, and γ is 4.5°-8°.

[0017] In some embodiments, the shortest distance between any position of the central axis of the lower tube and the bottom surface is equal.

[0018] In some embodiments, the two-wheeled vehicle further includes a side strip connected to the bottom of the foot pedal, the side strip being located outside the upper side tube and the lower side tube, and a bottom guard plate connected to the bottom of the side strip, the foot pedal, the side strip, and the bottom guard plate together defining a receiving cavity for accommodating a battery;

[0035] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] like Figure 1As shown, a two-wheeled vehicle according to an embodiment of the present invention includes a frame 1 and a bottom guard plate 2. The bottom guard plate 2 is disposed below the frame 1 and includes a front side surface 21 and a bottom surface 22 connected to each other. The bottom surface 22 is arranged inclined downward in the direction toward the front side surface 21, that is, the bottom surface 22 extends obliquely downward. The connection between the front side surface 21 and the bottom surface 22 has a chamfer.

[0037] According to the two-wheeled vehicle of this utility model embodiment, since the bottom surface 22 of the underbody plate 2 is inclined downward in the direction towards the front side 21, the lowest point of the vehicle body will be formed at the connection between the front side 21 and the bottom surface 22. The connection between the two is designed as a chamfer, that is, the connection is treated with a cut plane or a cut arc surface, which can effectively raise the height of the connection relative to the ground, so that the lowest point of the vehicle body is raised, and the overall vehicle passability is satisfied. Therefore, compared with related technologies, this utility model can keep the bottom body plate 2 within a safe height range from the ground to ensure the overall vehicle passability.

[0038] Specifically, the front side 21 can extend from bottom to top and tilt forward, that is, the front side 21 extends obliquely upward. The chamfer can be either a chamfer (i.e., a tangent plane) or a rounded corner (i.e., a tangent arc surface), based on the lowest point that can lift the bottom guard plate 2 (i.e., the connection between the front side 21 and the bottom surface 22), and is not specifically limited here.

[0039] It should be noted that, considering the overall vehicle passability, in actual use, the lowest point of the vehicle body is 40%-60% of the wheelbase. In this utility model, the area of ​​the vehicle near the front wheel 3 is tilted forward and to the bottom, and the bottom guard plate 2 can be raised as high as possible to satisfy the overall vehicle passability.

[0040] Furthermore, this invention is not limited to applications in two-wheeled electric vehicles, two-wheeled bicycles, two-wheeled gasoline vehicles, and other personal mobility vehicles. Taking a two-wheeled electric vehicle as an example, in related technologies, to ensure that shorter riders can place both feet on the ground when parked, the seat 8 o'clock position of the two-wheeled vehicle is lowered, and the bottom guard plate 2 is correspondingly lowered to accommodate the battery (or other drive structures). However, the two-wheeled vehicle of this invention, after lowering the seat 8 and bottom guard plate 2, can ensure overall vehicle passability by raising the lowest point of the bottom guard plate 2, i.e., by using a cut-plane or cut-arc surface design at the lowest point. This results in a simple structure, easy manufacturing, and comfortable riding for shorter riders.

[0041] like Figure 1 As shown, in some embodiments, the bottom guard plate 2 includes a transition surface 23 that connects the front side surface 21 and the bottom surface 22. The transition surface 23 forms a chamfer and extends in a downward direction and is inclined toward the bottom surface 22.

[0042] It is understandable that the underbody protection plate 2 is designed to be composed of a front side 21, a transition surface 23 and a bottom surface 22 connected in sequence. The transition surface 23 can raise the lowest point of the underbody protection plate 2 to ensure the vehicle's passability. Both the front side 21 and the transition surface 23 can be tilted towards the bottom, that is, the front side 21 and the transition surface 23 form the area of ​​the vehicle close to the front wheel 3.

[0043] The chamfer is preferably a beveled angle, that is, the transition surface 23 is a plane that extends from top to bottom and is inclined toward the bottom surface 22, in order to further reduce the difficulty of production.

[0044] like Figure 1 As shown, in some embodiments, the two-wheeled vehicle also includes a front wheel 3 and a rear wheel 4. The bottom guard plate 2 is located between the front wheel 3 and the rear wheel 4. The line connecting the lowest point of the front wheel 3 and the lowest point of the rear wheel 4 is the first line. The first line coincides with the support surface (such as the ground) of the two-wheeled vehicle. The distance between the connection point of the transition surface 23 and the bottom surface 22 and the first line is s, and s is 110mm to 130mm. For example, s can be 110mm, 112mm, 114mm, 116mm, 118mm, 120mm, 122mm, 124mm, 126mm, 128mm, 130mm, etc., but is not limited to the listed values. Other unlisted values ​​within this range are also applicable.

[0045] Understandably, by adopting the above structural design, the ground clearance of the bottom guard plate 2 can meet the actual riding requirements, that is, the distance between the vehicle body and the ground is within a safe height range, thus ensuring the overall vehicle passability.

[0046] Specifically, the front wheel 3 and the rear wheel 4 can be connected to the frame 1. The front side 21 is adjacent to the front wheel 3 relative to the bottom surface 22.

[0047] like Figure 1 As shown, in some embodiments, the two-wheeled vehicle also includes a foot pedal 5, which is located above the frame 1 and includes a front end 51, a foot pedal portion 52, and a rear end 53 connected in sequence. The foot pedal portion 52 extends toward the front end 51 and is arranged at a downward angle. The front end 51 is adjacent to the front wheel 3, and the rear end 53 is adjacent to the rear wheel 4. The foot pedal portion 52 is the area where the rider usually places their feet during riding.

[0048] Understandably, designing the foot pedal 52 to extend downwards at an angle increases the height difference between the foot pedal 5 and the seat 8, allowing more space above the foot pedal 5 to accommodate the rider's legs. This ensures a comfortable riding posture for taller riders, accommodating riders of different heights and expanding the applicability of the two-wheeled vehicle.

[0049] like Figure 1As shown, in some embodiments, the front end 51 extends from bottom to top and is arranged at an angle to the front. In other words, the front end 51 extends at an angle to the top to increase the angle between the front end 51 and the foot pedal 52. Under the premise of satisfying the overall vehicle structural performance, the space above the foot pedal 5 for accommodating the rider's legs is further widened, thereby providing conditions for taller riders to stretch their riding posture.

[0050] like Figure 1 As shown, in some embodiments, on the projection plane formed in the vertical and horizontal directions, the projection of the foot pedal 52 forms an angle α with the horizontal plane, and α is 5°-8°. For example, α can be 5°, 5.5°, 6°, 6.5°, 7°, 7.5°, 8°, etc., but is not limited to the listed values. Other unlisted values ​​within this range are also applicable.

[0051] like Figure 1 As shown, in some embodiments, on the projection plane formed in the vertical and horizontal directions, the projection of the front end 51 and the projection of the foot pedal 52 form an angle β, and β is 150°-170°. β can be, for example, 150°, 152°, 154°, 156°, 158°, 160°, 162°, 164°, 166°, 168°, 170°, etc., but is not limited to the listed values. Other unlisted values ​​within this range are also applicable.

[0052] It is understandable that by adopting the above parameter design, more space can be created above the pedal 5 to accommodate the rider's legs, without affecting the capacity of the battery (or other drive structures) between the bottom of the pedal 5 and the top of the bottom guard plate 2.

[0053] It should be noted that "battery" is not limited to lead-acid batteries, lithium batteries, etc.

[0054] like Figure 2 and Figure 3 As shown, in some embodiments, the frame 1 includes an upper tube 11 and a lower tube 12 arranged at intervals in the vertical direction, the foot pedal 5 is located on the top of the upper tube 11 and outside the upper tube 11, and the bottom guard plate 2 is located at the bottom of the lower tube 12 and outside the lower tube 12.

[0055] The front end 111 of the upper tube extends from bottom to top and is inclined forward, that is, the front end 111 of the upper tube extends obliquely upward to match the front end 51 of the foot pedal 5.

[0056] Understandably, the upper tube 11 provides support for the foot pedal 5, and the lower tube 12 provides support for the bottom guard plate 2, ensuring the structural strength of both. At the same time, the foot pedal 5 and the bottom guard plate 2 also shield the upper tube 11 and the lower tube 12 to reduce the corrosive damage of the external environment to the upper tube 11 and the lower tube 12, thus ensuring the service life of the frame 1.

[0057] like Figure 2 As shown, in some embodiments, the upper tube 11 includes a first tube segment 112 connected to the front end 111 of the upper tube. The first tube segment 112 corresponds to the foot pedal part 52. The central axis of each of the first tube segment 112 and the lower tube 12 forms an angle γ with the horizontal plane, and γ is 4.5°-8°. γ can be, for example, 4.5°, 5°, 5.5°, 6°, 6.5°, 7°, 7.5°, 8°, etc., but is not limited to the listed values. Other unlisted values ​​within this range are also applicable.

[0058] like Figure 3 As shown, in some embodiments, the shortest distance between any position of the central axis of the lower tube 12 and the bottom surface 22 is equal, that is, the bottom surface 22 of the bottom guard plate 2 conforms to the lower tube 12.

[0059] It is understandable that the upper tube 11 and the lower tube 12 adopt the above-mentioned structural design, which can ensure that there is enough leg space above the foot pedal 5, while effectively avoiding the problem that the upper tube 11 and the lower tube 12 are tilted too much, which is not conducive to the placement of the battery (or other drive structures) between them, and that the battery is tilted too much so that the positive and negative terminals of the battery cannot contact the electrolyte.

[0060] Specifically, the upper tube 11 and the lower tube 12 can be arranged to form a frame structure. The battery can be located in the frame structure and placed on the bottom protective plate 2. The bottom protective plate 2 is shaped to conform to the lower tube 12. Therefore, if the upper tube 11 and the lower tube 12 are tilted too much, it is not conducive to the placement of the battery.

[0061] like Figure 3 As shown, in some embodiments, the two-wheeled vehicle also includes a side strip 6 connected to the bottom of the foot pedal 5. The side strip 6 is located outside the upper side tube 11 and the lower side tube 12. The bottom guard plate 2 is connected to the bottom of the side strip 6. The foot pedal 5, the side strip 6 and the bottom guard plate 2 together define a receiving cavity for accommodating the battery. That is, the foot pedal 5, the side strip 6 and the bottom guard plate 2 can cover the upper side tube 11 and the lower side tube 12 in the receiving cavity.

[0062] The height difference between the foot pedal 5 and the bottom guard plate 2 is h1, and h1 is 190mm to 210mm. For example, h1 can be 190mm, 192mm, 194mm, 196mm, 198mm, 200mm, 202mm, 204mm, 206mm, 208mm, 210mm, etc., but it is not limited to the listed values. Other unlisted values ​​within this range are also applicable.

[0063] It is understandable that the height of the battery in the relevant technology is in the range of 167.5mm-170mm. In order to match the tallest battery, the height of the cavity used to house the battery needs to be reserved to meet the installation height of the largest battery. This can accommodate most batteries. Therefore, the height difference between the foot pedal 5 and the bottom guard plate 2 can be 200±10mm.

[0064] like Figure 4 As shown, in some embodiments, the two-wheeled vehicle also includes a seat 7 and a seat 8. The seat 7 is connected to the top of the upper tube 11, and the seat 8 is located on the top of the seat 7. The height difference between the seat 8 and the footrest 52 is h2, and h2 is 390mm to 430mm. For example, h2 can be 390mm, 395mm, 400mm, 405mm, 410mm, 415mm, 420mm, 425mm, 430mm, etc., but it is not limited to the listed values. Other unlisted values ​​within this range are also applicable.

[0065] It is understandable that designing the height difference between the seat 8 and the footrest 52 to the above parameters ensures that the height difference between the point of the seat 8 (i.e., the rider's sitting point) and the point of the footrest 52 (i.e., the center point of the foot) is within the above range. This ensures that the height of the seat 8 off the ground meets industry standards, such as 730mm, to match the parking needs of shorter riders.

[0066] Specifically, the seat 7 is not limited to being fastened to the top of the upper tube 11 by bolts. The seat cushion 8 is not limited to being connected to the seat 7 by a pivot hinge.
