Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a motorcycle. Background Technology

[0002] According to current national standards and regulations, motorcycle taillights must be equipped with brake lights, rear position lights, rear license plate lights, and rear turn signals. Currently, the conventional arrangement for motorcycle taillights is a separate design, with the brake lights and rear position lights located at the rear, the left and right rear turn signals on the sides of the vehicle, and the license plate light positioned in a suitable location to illuminate the license plate. This separate lighting arrangement often requires the fabrication of multiple plastic covers for matching and installation, resulting in low integration and making taillight installation cumbersome and inefficient. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide a motorcycle with a higher efficiency in rear taillight assembly.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] A motorcycle includes a frame, a running gear, a power unit, and a lighting unit. The running gear is at least partially located below the frame. The power unit is driven to the running gear. The lighting unit includes a taillight, which is substantially located behind the frame. The taillight includes a taillight housing and a taillight cover, which are fixedly connected and form a receiving space. The taillight also includes a circuit board and LEDs disposed within the receiving space. The LEDs are disposed on the circuit board. The LEDs include a first LED, a second LED, and a third LED. The first and third LEDs are substantially disposed in the middle of the taillight. The second LED has two mounting areas distributed along the width of the motorcycle, with the two mounting areas located on either side of the first LED.

[0006] Furthermore, a longitudinal plane is defined that is perpendicular to the width direction of the motorcycle and passes through the center of the motorcycle width. The longitudinal plane passes through the first LED and the third LED, and the first LED and the third LED are basically symmetrical about the longitudinal plane along the width direction of the motorcycle. The second LED is respectively set on both sides of the first LED and the third LED and is basically symmetrical about the longitudinal plane along the width direction of the motorcycle.

[0007] Furthermore, when the motorcycle is in normal driving condition, the first LED displays the first level of brightness, and when the motorcycle is braking, the first LED displays the second level of brightness, which is greater than the first level of brightness.

[0008] Furthermore, the rear lamp housing and rear lamp cover are basically symmetrically arranged about the longitudinal plane.

[0009] Furthermore, the motorcycle includes a main wiring harness and branch wiring harnesses electrically connected to the main wiring harness. The circuit board is electrically connected to the branch wiring harness, and a through hole is provided on the taillight housing. The branch wiring harness is electrically connected to the main wiring harness through the through hole.

[0010] Furthermore, the first LED is at least partially located above the third LED.

[0011] Furthermore, the light emission direction of the first and second LEDs is basically facing the rear of the motorcycle, and the light emission direction of the third LED is basically facing the lower part of the motorcycle. A light guide is provided on the rear light cover, and the light guide is located behind the third LED.

[0012] Furthermore, the third LED and the light guide are located at least partially below the taillight.

[0013] Furthermore, the motorcycle also includes a license plate holder, which is located substantially below the taillight and at least partially behind the running gear, with the light guide oriented toward the license plate holder.

[0014] Furthermore, when the third LED light is emitted, the light emitted by the third LED light shines onto the license plate holder through the light guide port.

[0015] The aforementioned motorcycle uses LEDs on a circuit board to implement the various functions of the taillight. This highly integrated design can greatly reduce the number of wiring harnesses at the rear of the motorcycle and the space required for wiring, thereby reducing the assembly steps and costs of the taillight and improving the assembly efficiency of the taillight.

[0025] To enable those skilled in the art to better understand the solutions of this application, the technical solutions in specific embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0026] Figure 1 illustrates a motorcycle 100, which includes a body 11, a running gear 12, a power unit 13, and a lighting unit 14. The body 11 includes a frame 111 and a plastic body panel 112. The frame 111 forms the basic framework of the motorcycle 100 and supports other components. The plastic body panel 112 is at least partially mounted on the frame 111, and a portion of the plastic body panel 112 forms a body cover on the outside of the motorcycle 100 to protect its internal parts. The running gear 12 is at least partially located below the frame 111 and is used to move the motorcycle 100. The power unit 13 is driven to the running gear 12 and generates power to control the movement of the running gear 12. The lighting unit 14 provides illumination for the motorcycle 100 in low-light conditions. To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The front, rear, left, right, top, and bottom sides are shown. It is understood that in this embodiment, the front-rear direction refers to the length direction of the motorcycle 100, the left-right direction refers to the width direction of the motorcycle 100, and the up-down direction refers to the height direction of the motorcycle 100.

[0027] like Figures 2 to 5As shown, the lighting assembly 14 includes a headlight 141 located in front of the motorcycle 100. The headlight 141 includes a headlight housing 1411 and a headlight cover 1412 disposed in front of the headlight housing 1411. The headlight housing 1411 is at least partially disposed on the frame 111 and at least partially located in front of the frame 111. The headlight housing 1411 is fixedly connected to the frame 111. The headlight housing 1411 and the headlight cover 1412 are fixedly connected and surround a headlight receiving space 1413. The headlight 141 also includes a position LED 1414 and a turn signal LED 1415 located within the headlight receiving space 1413. The position LED 1414 is used to provide position contour information of the motorcycle 100 when the lighting conditions are poor. The turn signal LED 1415 is used to indicate the turning status of the motorcycle 100. Both the position LED 1414 and the turn signal LED 1415 are disposed on the headlight housing 1411 and are fixedly connected to the headlight housing 1411. In the width direction of the motorcycle 100, the turn signal LED 1415 is at least partially disposed on both sides of the position LED 1414. Specifically, when the position LED 1414 is illuminated, the light from the position LED 1414 forms an illumination area on the headlight cover 1412. Similarly, when the turn signal LED 1415 is illuminated, the light from the turn signal LED 1415 also forms an illumination area on the headlight cover 1412. The headlight cover 1412 is provided with an illumination part 1412a, which is located inside the headlight cover 1412. When viewed along the length of the motorcycle 100, the illumination areas of the illumination part 1412a and the turn signal LED 1415 and the position LED 1414 on the headlight cover 1412 substantially overlap. The "inside the headlight cover 1412" mentioned above refers to the side of the headlight cover 1412 located inside the headlight housing space 1413. Understandably, the position LED 1414 and turn signal LED 1415 can be observed within the illumination area of ​​the headlight 141 through the illumination part 1412a. That is, when the driver or other person stands within the illumination area of ​​the headlight 141, they can directly observe the position LED 1414 and turn signal LED 1415. In this application, the angle range in the width direction of the motorcycle 100 in which the turn signal LED 1415 or position LED 1414 can be directly observed through the illumination part 1412a is defined as the maximum observation angle β; the angle of the maximum illumination range of the light from the turn signal LED 1415 or position LED 1414 in the width direction of the motorcycle 100 is defined as the maximum illumination angle α. As mentioned above, in the prior art, the maximum illumination angle α is basically consistent with the maximum observation angle β, and the maximum illumination range and the maximum observation range also basically overlap.

[0028] like Figure 2 , Figure 3 and Figure 4As shown, a refraction portion 1412b is also provided on the inner side of the headlight cover 1412. The refraction portion 1412b is basically located within the illumination area of ​​the turn signal bulb 1415 on the headlight cover 1412. That is, when viewed along the length direction of the motorcycle 100, the illumination portion 1412a and the refraction portion 1412b at least partially overlap, and the setting range of the refraction portion 1412b is smaller than the setting range of the illumination portion 1412a. The turn signal bulb 1415 is at least partially located outside the position bulb 1414. Correspondingly, the refraction portion 1412b is located on the headlight cover 1412 and is basically located on the outermost side of the headlight cover 1412. It should be explained here that a longitudinal plane 101 is defined that is perpendicular to the width direction of the motorcycle 100 and passes through the center of the width of the motorcycle 100. The "outer side" here refers to the side away from the longitudinal plane 101 along the width direction of the motorcycle 100, and the turn signal bulb 1415 is basically symmetrical about the longitudinal plane 101. The surface of the refractive portion 1412b near the turn signal bulb 1415 is essentially arc-shaped, thereby increasing the refraction angle and further expanding the illumination range of the turn signal bulb 1415 in the width direction of the motorcycle 100. This results in the maximum illumination angle α of the turn signal bulb 1415 being greater than the maximum observation angle β of the turn signal bulb 1415. In this application, the maximum illumination angle of the turn signal bulb 1415 is α, and the maximum observation angle of the turn signal bulb 1415 is β. α is greater than β, and the difference between α and β is greater than or equal to 15° and less than or equal to 25°. Furthermore, since the surface of the refractive portion 1412b is non-smooth, the refractive portion 1412b located on the headlight cover 1412 cannot smoothly transmit light. That is, the turn signal bulb 1415 cannot be directly observed through the refractive portion 1412b. Therefore, in the embodiment of this application, the maximum observation angle β is specifically the angle range within which the turn signal bulb 1415 or the position bulb 1414 can be directly observed through the area of ​​the illumination portion 1412a and the non-refractive portion 1412b. This method effectively reduces the maximum viewing angle β of the turn signal bulb 1415. Therefore, in this application, the difference between α and β can reach greater than or equal to 18° and less than or equal to 22°. Specifically, the difference between α and β is 20°. The above arrangement can minimize the direct viewing range of the turn signal bulb 1415, effectively improving the appearance of the headlight 141 while also increasing the refraction angle of light in the width direction of the motorcycle 100, making the turn signal bulb 1415 more recognizable in the width direction of the motorcycle 100, thereby improving the safety of the motorcycle 100.

[0029] like Figure 5 and Figure 6As shown, the longitudinal plane 101 passes through the position lamp 1414 and is substantially symmetrical about the longitudinal plane 101 in the width direction of the motorcycle 100. The headlight 141 also includes a refractive plate 1416 disposed within the headlight receiving space 1413. The refractive plate 1416 is at least partially disposed between the headlight housing 1412 and the position lamp 1414. The refractive plate 1416 is used to refract the light emitted by the position lamp 1414, thereby expanding the illumination angle of the position lamp 1414. In this application, the parts that at least partially realize the position signal function, such as the headlight housing 1411, the headlight housing 1412, the position lamp 1414, and the refractive plate 1416, are referred to as position lights, which together realize the position signal function for the motorcycle 100. It can be understood that, as the most important signal indicator for the motorcycle 100 on the road, the uniformity of the light emitted by the position light greatly affects the realization of its signal function. As an alternative implementation, the refractive plate 1416 in this application is disposed in front of the position lamp bead 1414. Specifically, the refractive plate 1416 includes an inner surface 1416a and an outer surface 1416b. The surface of the refractive plate 1416 facing the position lamp bead 1414 is the inner surface 1416a, and the surface of the refractive plate 1416 away from the position lamp bead 1414 is the outer surface 1416b. Understandably, the light from the position lamp bead 1414 enters the refractive plate 1416 from the inner surface 1416a and exits from the refractive plate 1416 from the outer surface 1416b. Specifically, the inner surface 1416a of the refractive plate 1416 is configured as a spherical surface concave towards the outer surface 1416b, and the diameter of this spherical surface is set to be greater than or equal to 3 mm and less than or equal to 5 mm. Figure 6As shown, a cross-section 102 perpendicular to the height direction of the motorcycle 100 is made through the center point of the sphere. The position LED 1414 forms an illumination plane 1414a on the cross-section 102 that is substantially parallel to the width direction of the motorcycle 100. The outer surface 1416b of the refractive plate 1416 is configured as an oval structure. Specifically, the outer surface 1416b includes a plane 1416c substantially parallel to the illumination plane 1414a and a transition surface 1416d located on the outer periphery of plane 1416c and gradually transitioning smoothly. In this application, the transition surface 1416d is an aspherical structure. The length of the illumination plane 1414a on the aforementioned cross-section 102 is defined as the illumination length H1, and the distance between the two ends of the inner surface 1416a on the cross-section 102 is defined as the inner refraction distance H2. As a specific embodiment, the ratio of the inner refraction distance H2 to the illumination length H1 is greater than or equal to 1 and less than or equal to 1.2. Furthermore, the length of the plane 1416c of the outer surface 1416b of the refractive plate 1416 on the cross section 102 is defined as the longitudinal length H3, and the ratio of the longitudinal length H3 to the irradiation length H1 is greater than or equal to 0.7 and less than or equal to 1; as an optimal implementation, the relationship between the curve Y of the transition surface 1416d on the cross section 102 and the irradiation length H1 satisfies the equation Y = -0.026X. 6 +0.2897X 5 -1.2141X 4 +2.3257X 3 -2.0426X 2 +0.5542X-0.0061. The above setting method can maximize the brightness of the light from the position lamp 1414 on the transition surface 1416d, and effectively improve the illumination uniformity of the position lamp.

[0030] Furthermore, a reasonable setting distance can further improve the light emission uniformity of the position LED 1414. The maximum distance between the position LED 1414 and the inner surface 1416a is defined as the diffusion distance H4, and the ratio of the diffusion distance H4 to the illumination length H1 is set to be greater than or equal to 0.6 and less than or equal to 1.2. More specifically, the setting scheme in this application can maintain the same light emission uniformity even when the distribution density of the position LED 1414 is reduced by 50%. This setting method can greatly reduce the material cost of the position LED 1414 and the manufacturing cost of related circuits, thereby reducing the energy consumption of the position LED 1414. In a preferred embodiment, the illumination length H1 of the position LED 1414 in this application is greater than or equal to 2.0 mm and less than or equal to 5.0 mm. Correspondingly, the inner refraction distance H2 of the inner surface 1416a of the refractive sheet 1416 is greater than or equal to 2.0 mm and less than or equal to 6.0 mm, the longitudinal length H3 of the plane 1416c of the outer surface 1416b of the refractive sheet 1416 on the cross-section 102 is greater than or equal to 1.5 mm and less than or equal to 5.0 mm, and the diffusion distance H4 between the position LED 1414 and the inner surface 1416a is greater than or equal to 1.2 mm and less than or equal to 6.0 mm. The position LED 1414 can be configured as an LED (light-emitting diode).

[0031] like Figure 6 and Figure 7 As shown, the motorcycle 100 also includes a wiring harness assembly 15. The wiring harness assembly 15 includes a main wiring harness 151 for connecting electrical appliances and a power source. The main wiring harness 151 extends substantially along the length of the motorcycle 100. The wiring harness assembly 15 also includes a branch wiring harness 152 electrically connected to the main wiring harness 151. The main wiring harness 151 also includes a wiring harness connector 1511 located at the connection point between the main wiring harness 151 and the branch wiring harness 152. One end of the branch wiring harness 152 is connected to the main wiring harness 151 via the wiring harness connector 1511, and the other end of the branch wiring harness 152 is connected to each electrical appliance. This allows each electrical appliance to be energized by connecting the branch wiring harness 152 to the main wiring harness 151, thereby reducing the length of the motorcycle 100's wiring harness, facilitating wiring harness arrangement, and improving the assembly performance of the motorcycle 100's wiring harness. In this application, the branch wiring harness 152 is also used to form an electrical connection between the headlight 141 and the main wiring harness 151.

[0032] The frame 111 includes a head tube 1111 located at the front of the frame 111, and a headlight 141 is at least partially disposed in front of the head tube 1111 and fixedly connected to the frame 111. Specifically, the headlight 141 is fixedly connected to the frame 111 via a headlight housing 1411. As previously described, the main wiring harness 151 extends substantially along the length of the motorcycle 100, specifically, the front end of the main wiring harness 151 extends to the head tube 1111 and is fixedly connected to the head tube 1111. As an alternative implementation, the fixing point between the main wiring harness 151 and the head tube 1111 is defined as the main wiring harness fixing point 1512. The branch wiring harness 152 is electrically connected to the main wiring harness 151 via a wiring harness connector 1511. The area where the connection point between the branch wiring harness 152 and the main wiring harness 151 is located is defined as the connection area. The wiring harness connector 1511 is disposed within the connection area, which is primarily located at the main wiring harness fixing point 1512. Specifically, the wiring harness connector 151 is at least partially located in front of the main wiring harness fixing point 1512. This connection method allows the main wiring harness 151 to be as close as possible to the headlight 141, and the branch wiring harness 152 to be led out at the closest point to the headlight 141, effectively reducing the distribution length of the branch wiring harness 152. Specifically, the branch harness 152 is configured as three branches, which are respectively connected to the position LED 1414 and the turn signal LEDs 1415 located on both sides of the position LED 1414. The three branches 152 can be connected into a single harness and then connected to the main harness 151 via a harness connector 1511. This reduces the number of connection points between the branch harness 152 and the main harness 151, requiring only one harness connector 1511 to connect the branch harness 152 and the main harness 151, thus improving the connection efficiency of the branch harness 152 and the main harness 151. The assembly efficiency of the main wiring harness 151 is improved. The three branch wiring harnesses 152 can also be electrically connected to the main wiring harness 151 via wiring harness connectors 1511. This ensures that if one branch wiring harness 152 fails, the other branch wiring harnesses 152 can still function normally. During maintenance, only the faulty part needs to be replaced or repaired, improving the reliability of the branch wiring harnesses 152. Furthermore, fixing the main wiring harness 151 to the head tube 1111 effectively balances the number and length of the branch wiring harnesses 152 extending to the left and right. One end of each branch wiring harness 152 is electrically connected to the main wiring harness 151, and the other end extends to each component according to the aforementioned requirements. During its extension, the branch wiring harness 152 is fixedly connected to the headlight housing 1411. The branch wiring harness 152 also includes a wiring harness fixing member 1521. The branch wiring harness 152 is fixedly connected to the headlight housing 1411 through the wiring harness fixing member 1521. Therefore, compared with the prior art where the branch wiring harness 152 is fixed to the frame 111, the fixed connection between the branch wiring harness 152 and the headlight housing 1411 makes the setting position of the wiring harness fixing member 1521 more flexible. This ensures that the arrangement of the branch wiring harness 152 will not affect other parts of the motorcycle 100, and can also reduce the length of the branch wiring harness 152.In this embodiment, along the extension direction of the branch harness 152, the minimum distance H5 between two adjacent harness fixing members 1521 is greater than or equal to 0 mm and less than or equal to 100 mm. This prevents the branch harness 152 from shifting during the motorcycle 100's operation, thereby preventing the branch harness 152 from detaching from the main harness 151. The branch harness 152 can be fixed using clips or wire clamps, and the harness fixing member 1521 can be a connector with multiple interfaces. Through this configuration, while simplifying the harness layout, the central wiring arrangement effectively reduces interference with other components of the vehicle, thus preventing wear and tear on other components caused by lateral wiring. Furthermore, the branch harness 152 can be repaired and reconnected by removing the headlight 141, thereby improving its maintainability. In addition, the branch wiring harness 152 is fixed on the headlight housing 1411, so that the layout requirements of the branch wiring harness 152 do not need to be considered during the installation of the headlight 141. This is conducive to improving the platform-based borrowing between the lighting assembly 14 and the branch wiring harness 152, and makes the headlight 141 less dependent on the vehicle frame 111 and other component placement positions.

[0033] Understandably, the number of branch harnesses 152 can be set to two ends, four segments, or other quantities depending on the number of electrical devices to be connected, as long as electrical connection with electrical devices can be achieved, it falls within the protection scope of this application.

[0034] like Figure 8 and Figure 9As shown, the lighting assembly 14 also includes a taillight 142 disposed at the rear end of the motorcycle 100, and the taillight 142 is electrically connected to the main wiring harness 142. The taillight 142 also includes a taillight housing 1421 and a taillight cover 1422 disposed behind the taillight housing 1421. The taillight housing 1421 and the taillight cover 1422 are fixedly connected and form a taillight receiving space 1423. The taillight 142 also includes an LED 1424 disposed in the taillight receiving space 1423 and a circuit board 1425. The LED 1424 is disposed on the circuit board 1425 and is electrically connected to the main wiring harness 151 through the circuit board 1425. Furthermore, the LED 1424 is also fixedly connected to the taillight housing 1421 through the circuit board 1425. As one possible implementation, the LED 1424 includes a first LED 1424a, a second LED 1424b, and a third LED 1424c. The first LED 1424a and the third LED 1424c are basically disposed in the middle of the taillight 142. The second LED 1424b is divided into two disposed areas and is disposed on both sides of the first LED 1424a and the third LED 1424c. A longitudinal plane 101 is defined that is perpendicular to the width direction of the motorcycle 100 and passes through the center of the width of the motorcycle 100. The taillight cover 1422 of the taillight 142 is basically symmetrical about the longitudinal plane 101 along the width direction of the motorcycle 100. Specifically, the longitudinal plane 101 passes through the first LED 1424a and the third LED 1424c, and both the first LED 1424a and the third LED 1424c are substantially symmetrical about the longitudinal plane 101 along the width direction of the motorcycle 100. The two areas of the second LED 1424b are also substantially symmetrical about the longitudinal plane 101 along the width direction of the motorcycle 100. The light emission directions of both the first LED 1424a and the second LED 1424b are substantially towards the rear of the motorcycle 100. The first LED 1424a is at least partially located above the third LED 1424c, and the light emission direction of the third LED 1424c is substantially towards the lower part of the motorcycle 100. Optionally, a light guide 1422a is provided on the rear lamp cover 1422. The third lamp 1424c and the light guide 1422a are at least partially located below the rear taillight 142. The light guide 1422a is basically located behind the third lamp 1424c and is used to guide the light emitted by the third lamp 1424c to a predetermined position. Figure 8As shown, the motorcycle 100 also includes a license plate holder 19 for mounting the motorcycle 100's license plate. The license plate holder 19 is located substantially below the taillight 142 and at least partially behind the running gear 12. In this application, the light guide 1422a is configured to face the license plate holder 19. When the third LED 1424c emits light, the light emitted by the third LED 1424c shines through the light guide 1422a onto the license plate holder 19, thereby guiding the light from the third LED 1424c to the license plate holder 19 to ensure that the license plate remains clearly visible during driving. Specifically, the rear lamp housing 1421 located basically behind the third LED 1424c, the circuit board 1425 in the area where the third LED 1424c is located, the rear lamp cover 1422 located behind the third LED 1424c, the light guide 1422a provided on the rear lamp cover 1422, and the third LED 1424c together realize the lighting function for the license plate bracket 19. For ease of reference, the above components are defined as license plate lighting module 1428 in this application. The license plate lighting module 1428 is at least partially located below the rear taillight 142. Correspondingly, the second LED 1424b is basically located in the part of the taillight 142 away from the longitudinal plane 101. The turn signal of the motorcycle 100 is transmitted by flashing the LEDs located in the right and left areas. Similarly, at least part of the taillight housing 1421, at least part of the taillight cover 1422, the circuit board 1425 area for setting the second LED 1424b, and the second LED 1424b together realize the transmission of the turn signal. In this application, the above-mentioned components that realize the turn function are defined as the first signal module 1426 of the taillight 142. That is, the first signal module 1426 is used to transmit the turn signal of the motorcycle 100. The first signal module 1426 is basically symmetrical about the longitudinal plane 101 along the width direction of the motorcycle 100.

[0035] In one specific implementation, the taillight 142 further includes a second signal module 1427. Specifically, the second signal module 1427 includes at least a partial first LED 1424a, at least a partial taillight housing 1421, at least a partial taillight cover 1422, and a circuit board 1425 area for mounting the first LED 1424a. These components together realize the information transmission of the second signal module 1427. Specifically, the second signal module 1427 can be used to transmit two types of vehicle operation information. The first LED 1424a is configured to include two levels of brightness, with a clear difference between the two levels of brightness, which can serve as a warning to those behind the motorcycle 100. The first LED 1424a is electrically connected to the controller or braking module of the motorcycle 100 via circuit board 1425. When the motorcycle 100 is in normal driving mode, the first LED 1424a displays a first level of brightness to indicate the motorcycle 100's position to vehicles behind. When the motorcycle 100 is braking, the first LED 1424a displays a second level of brightness, which is significantly brighter than the first level. In this case, the first LED 1424a transmits the motorcycle 100's braking information to vehicles behind. Through the above settings, the second signal module 1427 can simultaneously output the vehicle's position signal and braking signal to the rear of the motorcycle 100. The taillight 142 of this application, when adapted to the same taillight housing 1421, taillight cover 1422, and circuit board 1425, can simultaneously provide illumination for a license plate and transmit three types of vehicle information with only two signal modules. This highly integrated design significantly reduces the number of wiring harnesses and the wiring space required at the rear of the motorcycle 100, reduces the assembly steps and costs of the taillight, thereby improving the assembly efficiency of the taillight and enhancing the aesthetics of the taillight 142. Furthermore, during motorcycle 100 maintenance, only the taillight 142 needs to be removed to repair any faulty modules, improving the maintainability of the motorcycle 100.

[0036] Understandably, the taillight 142 can also distinguish the relevant signal modules according to actual operating requirements. In this application, the second signal module 1427 has only one illumination area, and the braking signal and position signal are transmitted simultaneously through this illumination area. According to the different vehicle's requirements for braking signal and position signal, the second signal module 1427 can also be set with two different illumination areas to transmit braking signal and position signal respectively. As long as the above signal transmission function can be achieved, it falls within the protection scope of this application.

[0037] As an alternative implementation, the taillight housing 1421 is provided with a wiring hole 1421a. Each module in the taillight 142 can be electrically connected via a branch wiring harness 152 and to the main wiring harness 142 via the wiring hole 1421a. This arrangement reduces the number of branch wiring harnesses 152 required for different modules to share a single circuit, allowing the taillight 142 to be electrically connected to the motorcycle 100 via only one branch wiring harness 152. This reduces the need for a single electrical connection during taillight 142 installation, improving assembly performance. Alternatively, the taillight housing 1421 can also have multiple wiring holes 1421a, allowing different modules to connect to the main wiring harness 142 via individual branch wiring harnesses 152, thus preventing a single module malfunction from affecting the normal operation of other modules.

[0038] 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.
