Description

Technical Field

[0001] This application relates to the field of vehicle engineering, and more particularly to an electric two-wheeled vehicle. Background Technology

[0002] An electric two-wheeler is a vehicle that can be powered by a battery. In some electric two-wheelers with pedals, the battery can be located below the pedals. To secure the battery, several metal retaining strips are typically installed above the battery and below the pedals.

[0003] If the power battery is fixed in the above manner, on the one hand, multiple metal pressure strips are required, and all metal pressure strips need to be disassembled and installed when the power battery is repaired or replaced, which makes it inconvenient to replace and repair the power battery; on the other hand, the metal pressure strips will rub against the power battery and the wiring harness connected to the power battery, which may damage the outer surface of the power battery and wiring harness in severe cases, resulting in a decrease in the life of the power battery and wiring harness. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide an electric two-wheeled vehicle whose power battery and the wiring harness connected to the power battery are not easily damaged and are easy to replace and repair.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] This application provides an electric two-wheeled vehicle, which includes a frame, a running system, a seat, a power battery, and a body cover. The running system includes a front wheel and a rear wheel, both of which are at least partially located under the frame. The seat is supported by the frame, and the power battery is also supported by the frame and located between the front wheel and the seat. The body cover includes a foot pedal located in front of the seat and covering the power battery. The body cover also includes a wire clamping plate, which is fixedly connected to the frame and located between the foot pedal and the power battery. The wire clamping plate covers the upper surface of the power battery, and at least a portion of the wire clamping plate abuts against the upper surface of the power battery. The wire clamping plate is made of plastic.

[0007] Furthermore, the pressure plate has several convex structures extending toward the power battery, which includes several battery cells, and the several convex structures respectively abut against the upper surface of the corresponding several battery cells.

[0008] Furthermore, a groove is formed between two adjacent convex structures, and the wire harness connected to the battery unit passes through the groove.

[0009] Furthermore, the body panel includes body side panels, which are distributed on the left and right sides of the power battery and cover at least part of the power battery. A wire clamp is located between the two body side panels, with a gap between the wire clamp and the body side panels, and a notch is formed near the edge of the body side panel. The wire harness connected to the power battery passes through the notch and the gap.

[0010] Furthermore, several ribs are formed on the side of the pressure plate opposite to the power battery, and the ribs abut against the bottom surface of the foot pedal.

[0011] Furthermore, the body panel includes a front panel and a rear panel, which are located on the front and rear sides of the foot pedal, respectively. Rubber protective parts are provided at the connection between the front panel and the foot pedal, and / or at the connection between the rear panel and the foot pedal.

[0012] Furthermore, the protective component forms a "U"-shaped groove, with the rear edge of the front baffle and / or the front edge of the rear baffle embedded in the groove of the corresponding protective component, and the foot pedal cover is provided on the upper surface of the protective component.

[0013] Furthermore, the foot pedals, front fender, and rear fender are all made of metal.

[0014] Furthermore, the front baffle includes a first connecting portion extending in the direction of the power battery, the rear baffle includes a second connecting portion extending in the direction of the power battery, and the foot pedal covers the first connecting portion and the second connecting portion along the height direction of the frame and is tightly connected to the first connecting portion and the second connecting portion.

[0015] Furthermore, the frame includes a pair of main beams distributed along the width of the frame, with the power battery disposed between the pair of main beams and supported by the main beams; the main beams are connected to support parts, which are tightly connected to pressure plates.

[0016] The electric two-wheeled vehicle provided in this application uses a plastic pressure plate between the power battery and the foot pedal. The pressure plate is pressed against the upper surface of the power battery to fix the power battery in place. The plastic pressure plate can reduce wear between itself and the power battery, as well as the wiring harness connecting the power battery. In addition, the power battery can be installed or removed by removing one of the pressure plates, which facilitates the replacement and maintenance of the power battery. Attached Figure Description

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, this application provides an electric two-wheeled vehicle 100, which includes a frame 11, a running system 12, a seat 13, and a power battery 14 (see [link]). Figure 2 The vehicle consists of a frame 11 and a body panel 15. The frame 11 forms the main frame of the electric two-wheeler 100. At least a portion of the running system 12 is located below the frame 11, and the running system 12 includes a front wheel 121 and a rear wheel 122. A seat 13 is located above and supported by the frame 11. A power battery 14 is located between the front wheel 121 and the seat 13, and is supported by the frame 11; the power battery 14 provides energy to drive the rear wheel 122. The body panel 15 covers at least a portion of the frame 11 and includes a footrest 151 located in front of the seat 13, which covers the power battery 14.

[0024] To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The electric two-wheeler 100 is shown in the front-back, left-right, and up-down directions. It should be noted that the front-back, left-right, and up-down directions in this document refer to the directions of the electric two-wheeler 100 on a horizontal road surface. In the following description of the technical solution of this application, the length direction of the frame 11 is parallel to the front-back direction of the electric two-wheeler 100, the width direction of the frame 11 is parallel to the left-right direction of the electric two-wheeler 100, and the height direction of the frame 11 is parallel to the up-down direction of the electric two-wheeler 100.

[0025] like Figure 2 As shown, in one implementation, the body panel 15 also includes a pressure plate 152. The pressure plate 152 is fixedly connected to the frame 11 and located between the foot pedal 151 and the power battery 14. The pressure plate 152 covers the upper surface of the power battery 14, and at least a portion of the pressure plate 152 abuts against the upper surface of the power battery 14, thereby limiting the vertical movement of the power battery 14 in the frame 11. The pressure plate 152 is made of plastic.

[0026] Specifically, there is a certain gap between the top surface of the pressure plate 152 and the foot pedal 151, and the foot pedal 151 needs to bear the pressure applied by the driver's leg. When the foot pedal 151 bears the pressure applied by the driver's leg, the elastic deformation of the foot pedal 151 and the gap between the foot pedal 151 and the top surface of the pressure plate 152 can provide a buffer area, so that part of the pressure on the pressure plate 152 is distributed, reducing the pressure on the pressure plate 152, thereby reducing the pressure on the power battery 14, and avoiding damage to the power battery 14 due to excessive pressure.

[0027] Furthermore, the pressure plate 152 is a plastic plate. When the pressure plate 152 is under pressure, it comes into contact with the wire harness connected to the power battery 14. Since the contact area between the pressure plate 152 and the wire harness is large, the pressure plate 152 can avoid cutting the wire harness.

[0028] The above design avoids excessive pressure exerted by the plastic pressure plate 152 on the power battery 14, which could damage the power battery 14, and also prevents the pressure plate 152 from cutting the wiring harness connected to the power battery 14 and causing damage to the wiring harness. When removing the power battery 14, simply removing the pressure plate 152 allows for the removal and installation of the power battery 14, facilitating replacement and maintenance.

[0029] like Figure 3 As shown, in one implementation, the pressure plate 152 has a plurality of convex structures 1521 extending toward the power battery 14. The power battery 14 includes a plurality of battery cells 141, and the plurality of convex structures 1521 respectively abut against the upper surface of the respective plurality of battery cells 141.

[0030] Specifically, the electric two-wheeler 100 includes at least two battery units 141, and the plurality of battery units 141 are distributed along the front-rear direction of the electric two-wheeler 100. A pressure plate 152 covers the upper surface of the plurality of battery units 141, and a number of protruding structures 1521 abut against the upper surface of the plurality of battery units 141 evenly, and the number of protruding structures 1521 abutting against the upper surface of each battery unit 141 is the same, thereby making the pressure on each battery unit 141 substantially the same.

[0031] Furthermore, a reference plane 101 is defined, which is perpendicular to the width direction of the frame 11. The pressure plate 152 is symmetrical along the reference plane 101. Several convex structures 1521 are divided into two groups: one group is located on one side of the reference plane 101 and distributed along the front-rear direction, and the other group is located on the other side of the reference plane 101 and distributed along the front-rear direction. The two groups of convex structures 1521 are symmetrically arranged along the reference plane 101 to avoid pressure concentration on either side of the power battery 14.

[0032] The above settings ensure that the pressure on the pressure plate 152 is evenly distributed to the power battery 14, which on the one hand improves the structural strength of the pressure plate 152, and on the other hand avoids pressure concentration that could damage the power battery 14.

[0033] In the implementation of this application, a wire groove 1522 is formed between two adjacent convex structures 1521, and the wire harness connected to the battery unit 141 is passed through the wire groove 1522, which optimizes the wire harness arrangement and avoids damage to the wire harness due to compression or friction.

[0034] like Figure 2 As shown, in one implementation, the body panel 15 includes a pair of body side panels 153, which are distributed on the left and right sides of the power battery 14. At least a portion of any body side panel 153 extends along the length direction of the frame 11 and covers at least a portion of the power battery 14.

[0035] The pressure plate 152 is located between a pair of vehicle side panels 153. There is a gap 102 between the pressure plate 152 and the vehicle side panels 153, and a notch 1523 is formed near the edge of the vehicle side panels 153. The wire harness connected to the power battery 14 passes through the notch 1523 and the gap 102.

[0036] With the above arrangement, at least part of the wire harness is passed through the notch 1523 and the gap 102, which further optimizes the wire harness arrangement and avoids the wire harness being squeezed by the pressure plate 152 and the power battery 14, or the wire harness rubbing against the pressure plate 152 and the power battery 14, which would cause damage to the wire harness.

[0037] like Figure 2 As shown, in one implementation, the pressure plate 152 has several ribs 1524 formed on the side face away from the power battery 14, and the ribs 1524 abut against the bottom surface of the foot pedal 151. The ribs 1524 can disperse stress, improve the structural strength of the pressure plate 152, and the contact area between the ribs 1524 and the foot pedal 151 is smaller than the contact area between the pressure plate 152 as a whole and the foot pedal 151, which reduces the area of ​​friction between the pressure plate 152 and the foot pedal 151, thereby reducing the wear of the pressure plate 152 and the foot pedal 151.

[0038] In one implementation, the body panel 15 includes a front panel 154 and a rear panel 155, which are located on the front and rear sides of the foot pedal 151, respectively. Both the front panel 154 and the rear panel 155 are made of metal, as is the foot pedal 151. The body panel 15 also includes a protective member 156, which is disposed at the connection between the front panel 154 and the foot pedal 151, with at least a portion of the protective member 156 located between the front panel 154 and the foot pedal 151. Alternatively, the protective member 156 may be disposed at the connection between the rear panel 155 and the foot pedal 151, with at least a portion of the protective member 156 located between the rear panel 155 and the foot pedal 151, to prevent direct contact between the foot pedal 151 and the front panel 154, and / or the foot pedal 151 and the rear panel 155. The protective member 156 is made of rubber.

[0039] With the above settings, a rubber material with a certain degree of elasticity is used as a protective component 156 to reduce the wear of the metal front baffle 154, rear baffle 155 and foot pedal 151, while preventing the metal front baffle 154, rear baffle 155 and foot pedal 151 from making abnormal noises due to collision.

[0040] like Figure 4 As shown, specifically, the protective member 156 forms a "U"-shaped groove 1561 with a groove opening 1561a. If the protective member 156 is located at the connection between the front baffle 154 and the foot pedal 151, the groove opening 1561a of the protective member 156 faces forward, and the rear edge of the front baffle 154 is embedded in the groove 1561 through the groove opening 1561a; if the protective member 156 is located at the connection between the rear baffle 155 and the foot pedal 151, the groove opening 1561a of the protective member 156 faces rearward, and the front edge of the rear baffle 155 is embedded in the groove 1561 through the groove opening 1561a. The foot pedal 151 covers the upper surface of the protective member 156.

[0041] By providing a protective element 156 with a slot 1561 and pressing the protective element 156 against the foot pedal 151 from above, the stability of the connection between the protective element 156 and the front baffle 154 and / or the rear baffle 155 can be improved.

[0042] In one implementation, the front baffle 154 includes a first connecting portion 1541 extending in the direction of the power battery 14, the rear baffle 155 includes a second connecting portion 1542 extending in the direction of the power battery 14, and the foot pedal 151 covers the first connecting portion 1541 and the second connecting portion 1542 along the height direction of the frame 11, and is tightly connected to the first connecting portion 1541 and the second connecting portion 1542.

[0043] In the implementation of this application, both the first connecting part 1541 and the second connecting part 1542 are provided with through holes extending in the vertical direction, and the foot pedal 151 is provided with a number of through holes of the same amount. Fasteners are passed through the through holes of the first connecting part 1541 and the through holes of the foot pedal 151 in sequence to tightly connect the foot pedal 151 to the front baffle 154; fasteners are passed through the through holes of the second connecting part 1542 and the through holes of the foot pedal 151 in sequence to tightly connect the foot pedal 151 to the rear baffle 155.

[0044] In some possible implementations, the first connecting part 1541 and the second connecting part 1542 are respectively provided with a plurality of snap-fit ​​positioning members, and the bottom of the foot pedal 151 is provided with a plurality of snap-fit ​​fasteners, which are correspondingly provided with the snap-fit ​​positioning members. Each of the snap-fit ​​fasteners can engage with the corresponding snap-fit ​​positioning member to fix the foot pedal 151 to the front baffle 154 and the rear baffle 155.

[0045] With the above configuration, the foot pedal 151 is tightly connected to the front baffle 154 and the rear baffle 155, so that the foot pedal 151 is supported and fixed by the front baffle 154 and the rear baffle 155, reducing the number of connection points to be welded to the frame 11 for fixing the foot pedal 151 and reducing the complexity of the frame 11 processing.

[0046] Furthermore, the frame 11 includes a pair of main beams 111, which are distributed along the width direction of the frame 11. The power battery 14 is disposed between the pair of main beams 111 and supported by the main beams 111. The main beams 111 are connected to a support portion 1111, which is tightly connected to the pressure plate 152.

[0047] Specifically, the support part 1111 is provided with a number of sheet metal structures 1111a, and the sheet metal structures 1111a are provided with mounting holes that penetrate through themselves. The pressure plate 152 is provided with a number of through holes that penetrate through itself. When viewed along the height direction of the frame 11, the mounting holes and through holes overlap. The pressure plate 152 can be fixed to the support part 1111 by fasteners passing through the through holes and mounting holes in sequence.

[0048] With the above configuration, the foot pedal 151 is connected to the front baffle 154 and the rear baffle 155, and the pressure plate 152 is connected to the main beam 111, thereby dispersing the pressure transmitted by the foot pedal 151 and the pressure plate 152, avoiding pressure concentration on the frame 11, and improving the structural strength of the frame 11.

[0049] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
