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] The headlights of electric two-wheeled vehicles are used to provide illumination. Headlights generally consist of a transparent lens, positioned in front of the light source, through which light is emitted. Because the lens is exposed and easily damaged, related technologies use an outer cover to protect both the lens and the light source. However, this outer cover increases the overall size of the headlight, raises manufacturing costs, and also blocks some light, affecting its illumination effect. Utility Model Content

[0004] This application provides an electric two-wheeled vehicle that can solve at least one of the above-mentioned technical problems.

[0005] Embodiments of this application provide an electric two-wheeled vehicle, including a frame, a body panel, a running system, a power system, and a headlight. The body panel at least partially covers the frame; the running system is at least partially located below the frame; the power system is connected to the running system to drive the running system; the headlight is located at the front of the frame. The headlight includes a protective cover, a light source assembly, and a lamp housing. The lamp housing has a mounting groove, the light source assembly is disposed within the mounting groove, and the protective cover seals the opening of the mounting groove. The protective cover includes a light-transmitting cover and a sidewall, the sidewall surrounding the outer periphery of the light-transmitting cover, and the light-transmitting cover being located in front of the light source assembly. Viewed from the front side of the headlight towards the rear, the light-transmitting cover is exposed, and the sidewall protrudes from the front side of the headlight beyond the light-transmitting cover.

[0006] In at least one embodiment, the light-transmitting cover and the sidewall are both integrally formed from a transparent material, and the height of the sidewall is greater than the wall thickness of the light-transmitting cover.

[0007] In at least one embodiment, the protective cover further includes a first mounting portion surrounding the outer periphery of the side wall; the lamp housing has a second mounting portion surrounding the outer periphery of the opening of the mounting groove, and the second mounting portion has a mounting groove, and the first mounting portion is inserted into the mounting groove along the front-rear direction of the headlight.

[0008] In at least one embodiment, the headlight further includes a seal disposed in the mounting groove and sealing the gap between the first mounting portion and the groove wall of the mounting groove.

[0009] In at least one embodiment, the headlight further includes a mounting frame, at least a portion of which is disposed in the mounting groove and connected to the lamp housing. The mounting frame has a light-transmitting hole through which the light source assembly is exposed on the front side of the headlight.

[0010] In at least one embodiment, the headlight further includes a heat sink disposed on the light source assembly, the heat sink being used to dissipate heat generated by the light source assembly.

[0011] The heat sink is directly connected to the light source component, which can efficiently conduct and dissipate the heat generated by the light source component, thereby effectively reducing the operating temperature of the light source component and avoiding problems such as light decay, color deviation or shortened lifespan caused by overheating; at the same time, it helps to maintain the stable output of the light source and ensure the consistency of lighting brightness and color temperature.

[0012] In at least one embodiment, the fixed frame shields the radiator when viewed from the front side of the headlight facing rearward.

[0013] In at least one embodiment, the light source assembly includes a position light source plate, the fixing frame includes a light-transmitting portion, and the position light source plate is disposed on the rear side of the light-transmitting portion.

[0014] In at least one embodiment, the headlight further includes a position lamp cover disposed on the front side of the light-transmitting portion, the position lamp cover being used to diffuse the light from the position lamp light source panel.

[0015] In at least one embodiment, the light source assembly includes a driving board, a high and low beam light source board, and a reflector bowl. The driving board is connected to the high and low beam light source board, the high and low beam light source board is disposed on the reflector bowl, the light from the high and low beam light source board is reflected by the reflector bowl onto the protective cover, and the driving board is disposed on the rear side of the reflector bowl.

[0016] In the electric two-wheeled vehicle of this application, the light from the light source assembly can be emitted through a light-transmitting cover, and the side wall surrounds the edge of the light-transmitting cover. This allows the side wall to not only protect the light-transmitting cover but also to minimize interference with the light dispersion. By thickening a portion of the protective cover's structure—that is, by increasing the height of the side wall without adding other components—the side wall protrudes forward of the headlight from the light-transmitting cover, thereby enhancing the structural strength of the protective cover. The protective cover integrates protection and light transmission, simplifying the headlight's structure and thus reducing the space occupied by the headlight. Attached Figure Description

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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 lighting system 60. It is understood that... Figure 1 The electric two-wheeler 100 shown is an electric-powered motorcycle.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] Please see Figure 2 In 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.

[0030] In some embodiments, the mid-frame 12 includes a pair of sub-beams 124 extending along the longitudinal 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.

[0031] Please see Figure 3 and Figure 4 In some embodiments, the lighting system 60 includes a headlight 61 disposed at the front of the electric two-wheeler 100. The headlight 61 includes a protective cover 611, a light source assembly 612, and a lamp housing 613. The lamp housing 613 has a mounting groove 6131, in which the light source assembly 612 is disposed. The protective cover 611 covers the opening of the mounting groove 6131. ​​The protective cover 611 includes an integrally formed light-transmitting cover 6111 and a side wall 6112. The side wall 6112 surrounds the outer periphery of the light-transmitting cover 6111, and the light-transmitting cover 6111 is located in front of the light source assembly 612. Viewed from the front side of the headlight 61 towards the rear, the light-transmitting cover 6111 is exposed, and the side wall 6112 protrudes from the front side of the headlight 61 beyond the light-transmitting cover 6111. The height of the side wall 6112 is greater than the wall thickness L1 of the light-transmitting cover 6111.

[0032] The light from the light source assembly 612 can be emitted through the light-transmitting cover 6111, and the side wall 6112 surrounds the edge of the light-transmitting cover 6111. This ensures that the side wall 6112 not only protects the light-transmitting cover 6111 but also does not easily interfere with the light dispersion. By thickening part of the structure of the protective cover 611—that is, by increasing the height of the side wall 6112 without adding other components—the side wall 6112 protrudes forward of the headlight 61 from the light-transmitting cover 6111, thereby enhancing the structural strength of the protective cover 611 and ensuring its protective function for the headlight 61. The protective cover 611 integrates protection and light transmission, reducing the number of components and simplifying the structure of the headlight 61. This helps to reduce the space occupied by the headlight 61 and simplify the assembly process of the headlight 61.

[0033] Please see Figure 3 and Figure 4 In some embodiments, the light-transmitting cover 6111 includes an outer wall surface 6111a and an inner wall surface 6111b disposed opposite to each other. The outer wall surface 6111a is the wall surface of the light-transmitting cover 6111 away from the light source assembly 612 and is located outside the headlight 61. The inner wall surface 6111b is the wall surface of the light-transmitting cover 6111 facing the light source assembly 612 and is located inside the headlight 61. The wall thickness L1 of the light-transmitting cover 6111 is the distance between the outer wall surface 6111a and the inner wall surface 6111b.

[0034] The sidewall 6112 includes a first surface 6112a, a second surface 6112b, a third surface wall 6112c, and a fourth surface 6112d. The first surface 6112a faces the front of the headlight 61, and the second surface 6112b faces the rear of the headlight 61. The first wall 6112c is connected to the outer edge of the light-transmitting cover 6111, and the second wall 6112d surrounds the outer periphery of the first wall 6112c and is the outer wall surface of the sidewall 6112.

[0035] The height D1 of the sidewall 6112 is the distance between the first surface 6112a and the second surface 6112b, and the wall thickness D2 of the sidewall 6112 is the distance between the first wall 6112c and the second wall 6112d. Understandably, the thickness of the sidewall 6112 at different locations along the front-rear direction of the headlight 61 can be set differently; that is, the wall thickness D2 of the sidewall 6112 at different locations can be set differently. The wall thickness D2 of the sidewall 6112 shown in the figure is only the wall thickness D2 of the sidewall 6112 at the marked location.

[0036] Please see Figure 3 and Figure 4 The wall thickness L1 of the light-transmitting cover 6111 is less than the height of the side wall 6112 and less than the wall thickness D2 of the side wall 6112, which makes the structural strength of the side wall 6112 greater than the structural strength of the light-transmitting cover 6111.

[0037] In some embodiments, "the sidewall 6112 protrudes from the front of the headlight 61 and extends beyond the light-transmitting cover 6111" can be understood as the light-transmitting cover 6111 being recessed within the space enclosed by the sidewall 6112, thereby protecting the light-transmitting cover 6111.

[0038] In some embodiments, both the light-transmitting cover 6111 and the sidewall 6112 are made of transparent material, such as transparent plastic. Both the sidewall 6112 and the light-transmitting cover 6111 have a light-transmitting function, improving the overall transparency of the headlight 61 and enhancing the lighting effect.

[0039] Please see Figure 3 and Figure 4 In some embodiments, the protective cover 611 further includes a first mounting portion 6113, which surrounds the outer periphery of the side wall 6112 and is located on the side of the side wall 6112 facing the lamp housing 613; the lamp housing 613 has a second mounting portion 6132, which surrounds the outer periphery of the opening of the mounting groove 6131 and has a mounting groove 6132a, and the first mounting portion 6113 is inserted into the mounting groove 6132a along the front-rear direction of the headlight 61.

[0040] The first assembly part 6113 is inserted into the conversion slot to achieve the covering of the protective cover 611 and the lamp housing 613, thereby forming a cavity that can accommodate the light source assembly 612. The insertion method is simple and convenient, and can ensure the assembly accuracy of the protective cover 611 and the lamp housing 613.

[0041] Please see Figure 3 and Figure 4 In some embodiments, the headlight 61 further includes a seal disposed in the mounting groove 6132a and sealing the gap between the first mounting part 6113 and the groove wall of the mounting groove 6132a.

[0042] The sealing design effectively enhances the dustproof and waterproof performance and structural stability of the headlamp 61. Specifically, on the one hand, it physically isolates the headlamp from external moisture, dust, and other contaminants, preventing them from penetrating the internal light source assembly 612 and ensuring the headlamp 61's lighting effect and lifespan. On the other hand, this design buffers the vibration and friction between the first assembly part 6113 and the second assembly part 6132, reducing the risk of seal failure due to long-term vibration. Furthermore, the sealing structure reduces the impact of thermal expansion and contraction on the assembly gap, ensuring the headlamp 61's seal durability under varying temperature conditions.

[0043] In some embodiments, the sealant is an adhesive, which fills the assembly gap by its flowability, thereby ensuring a tight seal.

[0044] In some embodiments, the seal is a rubber ring, which is a removable component, thereby facilitating the removal of the protective cover 611.

[0045] Please see Figure 3 and Figure 4 In some embodiments, the headlight 61 further includes a mounting frame 614, at least a portion of which is disposed in the mounting groove 6131 and connected to the lamp housing 613. The mounting frame 614 has a light-transmitting hole 6142 through which the light source assembly 612 is exposed on the front side of the headlight 61.

[0046] The structural design of the fixing frame 614 optimizes the mechanical strength and optical performance of the headlight 61. The fixing frame 614 is partially embedded in the mounting groove 6131 of the protective cover 611 and connected to the lamp housing 613, forming a stable support frame. This effectively disperses the stress on the lamp housing 613, enhances the overall structural rigidity, and prevents deformation or cracking caused by external impact or vibration. At the same time, the light-transmitting hole 6142 provided in the fixing frame 614 allows the light source assembly 612 to project light directly to the front, reducing obstruction of the light path and minimizing the impact on lighting brightness and uniformity.

[0047] Please see Figure 3 and Figure 4 In some embodiments, the headlight 61 further includes a heat sink 615 disposed on the light source assembly 612, the heat sink 615 being used to dissipate heat generated by the light source assembly 612.

[0048] The heat sink 615 is directly connected to the light source assembly 612, which can efficiently conduct and dissipate the heat generated by the light source assembly 612, thereby effectively reducing the operating temperature of the light source assembly 612 and avoiding problems such as light decay, color shift or shortened lifespan caused by overheating; at the same time, it helps to maintain the stable output of the light source and ensure the consistency of lighting brightness and color temperature.

[0049] Please see Figure 3 and Figure 4 In some embodiments, when viewed from the front side of the headlight 61 looking rearward, the mounting frame 614 conceals the radiator 615. Since the protective cover 611 is transparent, some internal components are visible through it. By concealing the radiator 615 with the mounting frame 614, the radiator 615 can be hidden behind the mounting frame 614, making it less likely to be exposed and improving the aesthetics of the headlight.

[0050] Please see Figure 3 and Figure 4In some embodiments, the light source assembly 612 includes a driving board 6121, a high and low beam light source board 6122, and a reflector bowl 6123. The driving board 6121 is connected to the high and low beam light source board 6122 via wires. The high and low beam light source board 6122 is disposed on the reflector bowl 6123. The light from the high and low beam light source board 6122 is reflected by the reflector bowl 6123 onto the protective cover 611. The driving board 6121 is disposed on the rear side of the reflector bowl 6123.

[0051] As a core optical component, the reflector bowl 6123 serves two purposes: firstly, it directionally reflects the direct light from the high and low beam light source panels 6122 to the protective cover 611, ensuring the main illumination function of the headlight 61; secondly, its bowl-shaped structure naturally shields the drive board 6121 and the circuit connection area behind it, reducing the impact of exposed internal electronic components on aesthetics. Simultaneously, the rear-mounted layout of the drive board 6121 fully utilizes the unused space behind the reflector bowl 6123, compressing the structural thickness in the front-rear direction while ensuring sufficient heat dissipation distance, thus facilitating a thinner and lighter headlight design.

[0052] Please see Figure 3 In some embodiments, a clearance hole 6123a is provided on the upper side of the reflector bowl 6123, and the high and low beam light source plate 6122 is disposed above the reflector bowl 6123, and projects light into the reflector bowl 6123 through the clearance hole 6123a.

[0053] In some embodiments, a heat sink 615 is attached to the back of the high and low beam light source plate 6122 to dissipate heat from the high and low beam light source plate 6122. Specifically, the heat sink 615 is connected to the high and low beam light source plate 6122 by screws.

[0054] In some embodiments, thermal grease (not shown) is applied between the heat sink 615 and the high and low beam light source plate 6122 to increase heat dissipation performance.

[0055] Please see Figure 3 and Figure 4 In some embodiments, the light source assembly 612 includes a position light source plate 6124, and the fixing frame 614 includes a light-transmitting portion 6141. The position light source plate 6124 is disposed on the rear side of the light-transmitting portion 6141. The position light source plate 6124 is connected to the drive plate 6121 via wires, and the drive plate 6121 drives the position light source plate 6124 to work.

[0056] The support structure of the fixed frame 614 ensures the positioning accuracy and shock resistance of the position lamp light source plate 6124, while the light-transmitting part 6141 enables unobstructed light transmission. At the same time, this layout compactly integrates the position lamp light source plate 6124 into the fixed frame 614 structure, reducing the space occupied by additional mounting brackets, simplifying the internal structure of the headlight 61, and facilitating the miniaturization design of the headlight 61.

[0057] In some embodiments, the position light source board 6124 is fixed to the fixing frame 614 by screws.

[0058] Please see Figure 3 and Figure 4 In some embodiments, the headlight 61 further includes a position lamp cover 616, which is disposed on the front side of the light-transmitting portion 6141 and is used to diffuse the light from the position lamp light source plate 6124.

[0059] The position light inner cover 616 is located on the front side of the light-transmitting part 6141, which can actively scatter the direct light from the position light source plate 6124, effectively eliminating local bright spots or dark areas, and making the brightness distribution of the emitted light more uniform.

[0060] In some embodiments, the position light inner cover 616 is embedded in the front side of the light-transmitting part 6141, and the position light inner cover 616 and the light-transmitting part 6141 are formed by two-color injection molding. For example, the position light inner cover 616 is made of yellow light-transmitting plastic, and the light-transmitting part 6141 is made of transparent plastic.

[0061] Please see Figure 3 and Figure 4 In some embodiments, two position light source plates 6124 are provided, which are separated by one side, one of which is located on the upper edge of the fixing frame 614 and the other is located on the lower edge of the fixing frame 614. Correspondingly, two position light inner covers 616 are also provided, with each position light source plate 6124 corresponding to one position light inner cover 616.

[0062] 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.
