Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to an electric two-wheeled vehicle. Background Technology

[0002] With the increasing emphasis on environmental protection and energy conservation in society, electric two-wheelers, as a green, energy-saving, and emission-reducing mode of transportation, are playing an increasingly important role in public transportation.

[0003] Currently, electric two-wheelers are increasingly being designed to be smaller and lighter. In the design of electric two-wheelers, the brake line is a key component of the hydraulic braking system, responsible for transmitting high-pressure brake fluid between the master cylinder (or ABS pump) and the caliper, transferring the driver's braking force to the wheels to achieve deceleration or stopping. A portion of the brake line needs to extend from the frame through the front shock absorber to the caliper position. Because the inner tube and bottom cylinder of the front shock absorber move relative to each other during driving, this part of the brake line will also vibrate frequently under the high-frequency vibration conditions of the electric two-wheeler, affecting driving safety. Utility Model Content

[0004] The purpose of this application is to provide an electric two-wheeled vehicle that improves the stability of oil pipe installation on the vehicle.

[0005] This application provides an electric two-wheeled vehicle, including a frame, a running system, a suspension system, and a braking system. The frame includes a front frame, a mid-frame, and a rear frame; the running system includes a front wheel, which is disposed below the front frame; the suspension system includes a front shock absorber, which connects the front wheel and the front frame, and includes a base tube; the braking system includes a front oil pipe, a front caliper, and a brake lever, with the brake lever disposed on the front frame and the front oil pipe connecting the brake lever and the front caliper; the front caliper is used to control the braking of the front wheel. The braking system includes a first fixing member, which includes an integrally formed first clamping part and a hook, the first clamping part clamping the front oil pipe and installing it on the base tube, the hook forming a limiting space; the front oil pipe includes a first section, a second section, and a third section connected in sequence, the first section being disposed on the front frame, a portion of the second section being located in the limiting space and having a certain amount of movement within the limiting space, and the first clamping part clamping a portion of the third section.

[0006] In at least one embodiment, the braking system includes an elastic sleeve fitted onto a front oil pipe. The elastic sleeve has two limiting rings spaced apart along the length of the front oil pipe, and a first clamping portion is located between the two limiting rings.

[0007] In at least one embodiment, the bottom cylinder has a mounting portion; the first clamping portion includes an annular limiting portion and two first assembly portions, the annular limiting portion and the first assembly portions being an integrally formed elastic metal part; the annular limiting portion clamps the front oil pipe, the annular limiting portion having two oppositely arranged first ends, each first end being connected to a first assembly portion, and the two first assembly portions being detachably connected to the mounting portion.

[0008] In at least one embodiment, the first clamping portion is configured to elastically deform the two first ends to move away from each other, thereby forming a first opening between the two first assembly portions, the first opening allowing the front oil pipe to enter the annular limiting portion.

[0009] In at least one embodiment, the first fastener includes a connector, the first assembly part is provided with a connecting hole, the mounting part is sandwiched between two first assembly parts, and the connector passes through the connecting hole and through the mounting part.

[0010] In at least one embodiment, the braking system further includes a rear oil pipe, a wheel speed sensing wire, and a second fixing member; the second fixing member clamps the rear oil pipe and the wheel speed sensing wire and mounts them to the rear frame.

[0011] In at least one embodiment, the second fastener includes a second clamping portion, which is bent to form a first groove and a second groove, with a portion of the rear oil pipe located in the first groove and a portion of the wheel speed sensing line located in the second groove.

[0012] In at least one embodiment, the second clamping part includes two opposing second ends, each second end being provided with a second mounting part, the second mounting part and the second clamping part being an integrally formed elastic metal part, and the second mounting part being detachably connected to the rear frame.

[0013] In at least one embodiment, the second clamping portion is configured to elastically deform the two second ends to move away from each other, thereby forming a second opening between the two second assembly portions. The second opening allows the front oil pipe to enter the first groove and the wheel speed sensing line to enter the second groove.

[0014] In at least one embodiment, the braking system further includes a rear caliper, the running system includes a rear wheel, and the rear caliper is used to control the braking of the rear wheel; the rear oil pipe includes a fourth section, a fifth section and a sixth section connected in sequence, the fourth section is disposed on the front frame and connected to the brake lever, the fifth section is disposed on the middle frame, and the sixth section is disposed on the rear frame and connected to the rear caliper.

[0015] The electric two-wheeler of this application integrates the first clamping part with the hook, allowing for complete fixation of the first fixing component simply by installing the first clamping part onto the base cylinder, simplifying the fixing process of the front oil pipe. The first clamping part fixes the front oil pipe to the base cylinder by clamping the third section of the front oil pipe, while the hook confines the second section of the front oil pipe within a limited space. When the vehicle vibrates, the third section is clamped by the first clamping part, preventing the entire front oil pipe from swaying relative to the base cylinder. Furthermore, the second section is also limited by the hook, preventing the portion of the front oil pipe within the limited space from moving away from the front frame, thus improving the installation stability of the front oil pipe on the vehicle. The hook restricts the movement range of the second section within the limited space, and when the vehicle bumps, it can adapt to the dynamic changes of the front shock absorber with a certain amount of movement allowance, allowing the second section of the front oil pipe to freely adjust its direction when the suspension system moves, reducing fatigue fracture of the front oil pipe due to insufficient length or excessively small bending radius; and it absorbs vibration energy through its own elastic deformation, reducing stress concentration at the hook fixing position.

[0022] In the description of the embodiments in this application, the words "exemplary," "or," and "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary," "or," and "for example" is intended to present the relevant concepts in a specific manner.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application's specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0024] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the embodiments and features described below can be combined with each other.

[0025] like Figure 1 and Figure 2 As shown, this application provides an electric two-wheeled vehicle 100, which includes a frame 10, a body panel 20, a running gear 30, a suspension system 40, a power system 50, and a braking system 60. It is understood that... Figure 1 The electric two-wheeler 100 shown is an electric-powered motorcycle.

[0026] The body panel 20 at least partially covers the frame 10. The running gear 30 is at least partially disposed under the frame 10, and includes front wheels 31 and rear wheels 32. A suspension system 40 connects the front wheels 31 and rear wheels 32 to the frame 10. A power system 50 is supported by the frame 10, connected to the running gear 30, and used to drive the running gear 30. For example, the power system 50 drives the rear wheels 32 to rotate.

[0027] To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 and Figure 2 The directions shown are front, back, left, right, up, and down. In this embodiment, the front, back, left, right, up, and down directions refer to the directions when the electric two-wheeled vehicle 100 is on a horizontal plane. The front-back direction refers to the length direction of the electric two-wheeled vehicle 100 provided in this application. The left-right direction refers to the width direction of the electric two-wheeled vehicle 100 provided in this application. The up-down direction refers to the height direction of the electric two-wheeled vehicle 100 provided in this application.

[0028] As one implementation method, such as Figure 2 As shown, the frame 10 includes a front frame 11, a middle frame 12, and a rear frame 13 connected in sequence. Viewed along the length of the electric two-wheeler 100, the frame 10 is substantially symmetrical about its central axis.

[0029] In some embodiments, the front frame 11 includes a head tube 111 and a main tube 112, with the main tube 112 connected to the middle portion of the head tube 111. The front wheel 31 is connected to the head tube 111 via a suspension system 40, specifically, the suspension system 40 includes a front shock absorber 41, through which the front wheel 31 is connected to the head tube 111.

[0030] Please see Figure 2In some embodiments, the mid-frame 12 includes a pair of longitudinal beams 121 extending along the front-rear direction of the electric two-wheeler 100 and a crossbeam 122 extending along the width direction of the electric two-wheeler 100 and connecting the two longitudinal beams 121. Exemplarily, the two longitudinal beams 121 are disposed on the left and right sides of the electric two-wheeler 100, with one end of each beam connected to the left and right sides of the lower part of the front frame 11, and the other end connected to the rear frame 13. The longitudinal beams 121 and the crossbeam 122 enclose an accommodating space 123. Specifically, the power system 50 includes a battery assembly 51, which is disposed within the accommodating space 123.

[0031] Please see Figure 2 In some embodiments, the mid-frame 12 includes a pair of sub-beams 124 extending along the front-rear direction of the electric two-wheeler 100. The two sub-beams 124 are disposed on the left and right sides of the electric two-wheeler 100 and below the longitudinal beam 121. One end of the sub-beam 124 is connected to the bottom of the main beam 112, and the other end of the sub-beam 124 is connected to the rear frame 13.

[0032] Please see Figure 2 In some embodiments, the rear frame 13 includes a pair of side tubes 131 spaced apart along the width direction of the electric two-wheeler 100, the side tubes 131 being connected to the mid-frame 12. Specifically, one end of the side tube 131 is connected to the sub-beam 124, and the other end extends toward the rear of the electric two-wheeler 100. The suspension system 40 also includes a rear shock absorber 42, which connects the rear wheel 32 to the side tubes 131.

[0033] Please see Figure 2 and Figure 3 In some embodiments, the front shock absorber 41 connects the front wheel 31 to the front frame 11, and the front shock absorber 41 includes a base cylinder 411. The base cylinder 411 is a rigid shell structure outside the shock absorber, which contains damping components. The base cylinder 411 can support the overall mechanical load of the shock absorber, and at the same time transmit road impacts to the damping components through the rigid structure. For example, the damping components include springs, dampers, hydraulic lines, and other components.

[0034] The braking system 60 includes a front oil pipe 61, a front caliper 62, and a brake lever 63. The brake lever 63 is mounted on the front frame 11. The front oil pipe 61 connects the brake lever 63 and the front caliper 62. The front caliper 62 is used to control the braking of the front wheel 31. Specifically, the front oil pipe 61 delivers oil to the front caliper 62, causing the front caliper 62 to brake the front wheel 31.

[0035] The braking system 60 includes a first fixing member 64, which includes an integrally formed first clamping part 641 and a cable hook 642. The first clamping part 641 clamps the front oil pipe 61 and is installed on the bottom cylinder 411. The cable hook 642 encloses and forms a limiting space 6421. The front oil pipe 61 includes a first section 611, a second section 612, and a third section 613 connected in sequence. The first section 611 is disposed on the front frame 11. A portion of the second section 612 is located in the limiting space 6421 and has a certain amount of movement within the limiting space 6421. The first clamping part 641 clamps a portion of the third section 613.

[0036] By integrating the first clamping part 641 with the hook 642, the first fixing member 64 can be fixed as a whole simply by installing the first clamping part 641 onto the base cylinder 411, simplifying the fixing steps for the front oil pipe 61. The first clamping part 641 fixes the front oil pipe 61 to the base cylinder 411 by clamping the third section 613 of the front oil pipe 61, and the hook 642 can restrict the second section 612 of the front oil pipe 61 within the limiting space 6421. When the vehicle vibrates, the third section 613 is clamped by the first clamping part 641, making it difficult for the entire front oil pipe 61 to shake relative to the base cylinder 411. Furthermore, the second section 612 is also limited by the hook 642, making it difficult for the portion of the front oil pipe 61 located in the limiting space 6421 to move away from the front frame 11, thus improving the installation stability of the front oil pipe 61 on the vehicle.

[0037] The hook 642 can restrict the range of motion of the second section 612 within the limiting space 6421, and can adapt to the dynamic changes of the front shock absorber 41 with a certain amount of movement when the vehicle is bumpy. This allows the second section 612 of the front oil pipe 61 to freely adjust its direction when the suspension system 40 moves, reducing the fatigue fracture of the front oil pipe 61 caused by insufficient length being stretched or too small bending radius. It also absorbs vibration energy through its own elastic deformation, reducing stress concentration at the fixed position of the hook 642.

[0038] Please see Figure 3 and Figure 4 In some embodiments, the bottom cylinder 411 has a mounting portion 4111. The first clamping portion 641 includes an annular limiting portion 6411 and two first mounting portions 6412, the annular limiting portion 6411 and the first mounting portions 6412 being integrally formed elastic metal parts. The annular limiting portion 6411 clamps the third segment 613 of the front oil pipe 61. The annular limiting portion 6411 has two opposing first ends 6411a, each first end 6411a being connected to a first mounting portion 6412, and the two first mounting portions 6412 being detachably connected to the mounting portion 4111.

[0039] The annular limiting part 6411 is combined with two first assembly parts 6412 through a one-piece molded elastic metal part design, utilizing the elastic deformation capability of metal to achieve stable clamping of the front oil pipe 61. The opposing first ends 6411a of the annular limiting part 6411 generate a uniform radial constraint force on the front oil pipe 61 during clamping, while the detachably connected first assembly parts 6412 cooperate with the mounting part 4111 of the bottom cylinder 411, ensuring both assembly firmness and ease of maintenance. The overall structure can effectively suppress the displacement of the front oil pipe 61 under the vibration condition of the shock absorber, while the modular design simplifies the disassembly and assembly process, taking into account both fatigue resistance and maintenance convenience.

[0040] Understandably, the "elasticity" in elastic metal parts refers to the deformability of the metal parts. For example, materials such as iron, aluminum, and alloys can deform by bending.

[0041] Please see Figure 3 and Figure 4 In some embodiments, the first clamping part 641 can elastically deform the two first ends 6411a to move away from each other, so as to form a first opening 6413 between the two first assembly parts 6412, the first opening 6413 allowing the third section 613 of the front oil pipe 61 to enter the annular limiting part 6411.

[0042] The elastic deformation of the first clamping part 641 causes the two first ends 6411a to expand outward, forming a first opening 6413, which facilitates the quick insertion of the front oil pipe 61 into the annular limiting part 6411. Subsequently, the annular limiting part 6411 clamps itself through elastic deformation, which improves assembly efficiency and ensures the stable fixation of the front oil pipe 61, making it suitable for convenient installation and maintenance in confined spaces. After clamping, the annular limiting part 6411 can close or reduce the first opening 6413, thereby preventing the front oil pipe 61 from detaching from the annular limiting part 6411.

[0043] In some embodiments, the first clamping portion 641 and the annular limiting portion 6411 are formed by bending a sheet of metal material.

[0044] Please see Figure 3 and Figure 4 In some embodiments, the first fastener 64 includes a connector 643, and the first assembly portion 6412 is provided with a connecting hole 6412a. The mounting portion 4111 is sandwiched between two first assembly portions 6412, and the connector 643 passes through the connecting hole 6412a and through the mounting portion 4111. For example, the connector 643 includes a bolt and a nut.

[0045] The connector 643 passes through the connecting holes 6412a of the two first assembly parts 6412 and is fixed to the mounting part 4111 of the base cylinder 411, thus achieving a stable connection between the first clamping part 641 and the base cylinder 411. This symmetrical clamping installation method can evenly distribute the clamping force, avoiding the problem of uneven load caused by unilateral force, while facilitating disassembly, maintenance, or replacement of parts. It balances structural rigidity and assembly flexibility, and is conducive to long-term reliable fixation under vehicle vibration.

[0046] In some embodiments, the hook 642 is formed by bending a metal wire. The hook 642 has two ends, one of which is connected to the first clamping part 641. An inlet 6422 is provided between the two ends, through which the front oil pipe 61 can enter the limiting space 6421 of the hook 642.

[0047] Please see Figure 2 and Figure 5 In some embodiments, the braking system 60 further includes a rear oil pipe 65, a wheel speed sensing line 66, and a second fixing member 67; the second fixing member 67 clamps the rear oil pipe 65 and the wheel speed sensing line 66 and is mounted on the rear frame 13.

[0048] The rear oil pipe 65 and wheel speed sensor line 66 are integrated and fixed to the rear frame 13 by the second fastener 67, which optimizes the spatial layout of the braking system 60 and fixes the rear oil pipe 65 and wheel speed sensor line 66 to reduce the risk of pipeline interference. At the same time, the integrated clamping structure ensures that the rear oil pipe 65 and wheel speed sensor line 66 remain stable during vehicle driving vibration, avoids wear caused by loosening or friction, and improves the reliability and durability of the braking system 60.

[0049] In some embodiments, the wheel speed sensing line 66 is a signal transmission cable connecting the wheel speed sensor and the ABS system (Anti-lock Braking System), responsible for transmitting the wheel speed pulse signal collected by the wheel speed sensor to the ABS system in real time.

[0050] Please see Figure 2 In some embodiments, the braking system 60 further includes a rear caliper 68, which is disposed on the rear wheel 32 and connected to a rear hydraulic line 65. The rear hydraulic line 65 is connected to a brake lever 63. The rear caliper 68 is used to control the braking of the rear wheel 32. Specifically, the rear hydraulic line 65 delivers hydraulic fluid to the rear caliper 68, causing the rear caliper 68 to brake the rear wheel 32.

[0051] Please see Figure 5 and Figure 6In some embodiments, the second fixing member 67 includes a second clamping portion 671, which is bent to form a first groove 6711 and a second groove 6712. A portion of the rear oil pipe 65 is located in the first groove 6711, and a portion of the wheel speed sensing line 66 is located in the second groove 6712. The first groove 6711 and the second groove 6712 are in communication.

[0052] The bending and deformation of the second clamping part 671 forms the first groove 6711 and the second groove 6712, thereby achieving separate positioning of the rear oil pipe 65 and the wheel speed sensing line 66, and avoiding mutual squeezing or friction between the two.

[0053] Please see Figure 5 and Figure 6 In some embodiments, the second clamping part 671 includes two opposing second ends 6713, each second end 6713 being provided with a second mounting part 672, the second mounting part 672 being an integrally formed elastic metal part with the second clamping part 671, and the second mounting part 672 being detachably connected to the rear frame 13.

[0054] Please see Figure 5 and Figure 6 In some embodiments, the second clamping part 671 elastically deforms so that the two second ends 6713 move away from each other to form a second opening 673 between the two second assembly parts 672. The second opening 673 allows the front oil pipe 61 to enter the first groove 6711 and the wheel speed sensing line 66 to enter the second groove 6712.

[0055] The two second ends 6713 of the second clamping part 671 and the second assembly part 672 form a symmetrical clamping structure, which ensures the rear oil pipe 65 and the wheel speed sensing line 66 are firmly fixed, while utilizing the elasticity of metal to adapt to different pipe diameters and provide a buffering and vibration reduction effect. The detachable second assembly part 672 simplifies the installation and maintenance process and improves maintenance convenience.

[0056] Understandably, the second opening 673 can be narrowed or closed by the second ends 6713 approaching each other, thereby preventing the oil pipe 65 from disengaging from the second opening 673 and the second clamping part 671.

[0057] Please see Figure 5 and Figure 6 In some embodiments, the rear frame 13 includes a mounting bracket 132 disposed on one of the side tubes 131. A second fastener 67 is mounted to the mounting bracket 132. For example, two second mounting parts 672 are stacked and secured to the mounting bracket 132 by bolts and nuts.

[0058] Please see Figure 2 and Figure 5In some embodiments, the rear oil pipe 65 includes a fourth segment 651, a fifth segment 652 and a sixth segment 653 connected in sequence. The fourth segment 651 is disposed on the front frame 11 and connected to the brake lever 63, the fifth segment 652 is disposed on the middle frame 12, and the sixth segment 653 is disposed on the rear frame 13 and connected to the rear caliper 68.

[0059] This design optimizes the brake line routing through a segmented rear brake line layout. The fourth segment 651 connects the front frame 11 and the brake lever 63 for flexible operation. The fifth segment 652 extends along the mid-frame 12 to reduce stress caused by bending. The sixth segment 653 is fixed to the rear frame 13 to directly drive the rear caliper 68, ensuring efficient transmission of braking force. The segmented structure balances the flexibility of the lines during vehicle operation with a reasonable layout, reducing the risk of wear on the rear brake line 65.

[0060] Please see Figure 3 In some embodiments, the braking system 60 includes an elastic sleeve 69, which is fitted onto the third section 613 of the front oil pipe 61. The elastic sleeve 69 has two limiting rings 691, which are spaced apart along the length of the front oil pipe 61. A first clamping part 641 is located between the two limiting rings 691.

[0061] The elastic sleeve 69 increases the friction between the front oil pipe 61 and the first clamping part 641, making it difficult for the first fixing member 64 to move relative to the front oil pipe 61. The first clamping part 641 is located between the two limiting rings 691, which restricts the relative movement of the first clamping part 641 and the elastic sleeve 69, thereby restricting the movement of the first clamping part 641 in the length direction of the front oil pipe 61.

[0062] Please see Figure 3 and Figure 5 In some embodiments, the elastic sleeve 69 includes a first elastic sleeve 692 and a second elastic sleeve 693. The first elastic sleeve 692 is disposed on the front oil pipe 61, and the second elastic sleeve 693 is disposed on the fourth section 651 of the rear oil pipe 65. The second clamping part 671 clamps the second elastic sleeve 693 to improve the clamping stability of the second clamping part 671 on the rear oil pipe 65.

[0063] In some embodiments, the elastic sleeve 69 is a rubber sleeve.

[0064] In some embodiments, the rear oil pipe 65 is also secured to the frame 10 by cable ties.

[0065] In addition, those skilled in the art may make other changes within this application. Of course, all such changes made in accordance with this application should be included within the scope disclosed in this application.
