Description

Technical Field

[0001] The present invention relates to the technical field of motorcycles, and particularly to a rearview mirror and a motorcycle with multiple lighting functions. Background Art

[0002] A motorcycle is a two-wheeled or three-wheeled vehicle driven by a fuel power device or an electric power device and steered by a handlebar to turn the front wheel.

[0003] As a safety component of a motorcycle, a rearview mirror is a tool for users to directly obtain information behind the motorcycle. Compared with the rearview mirror of an automobile, the structure of the rearview mirror of a motorcycle is simpler, generally including a frame body, a back shell and a rearview lens. The frame body is arranged on the motorcycle body, the back shell is arranged on the frame body, and the rearview lens is arranged on the back shell.

[0004] With the continuous acceleration of the urbanization process in China, the ownership of automobiles has increased year by year, and urban roads have become extremely congested. In cities where motorcycles are not prohibited, motorcycles with no parking fees and low usage costs are favored by many people.

[0005] For users, firstly, it is difficult to determine whether the width is suitable for passing when traveling at night in narrow areas (narrow roads, narrow bridges, between two cars, etc.), and scratches are likely to occur; secondly, some motorcycles do not conform to ergonomics, and there is a problem that it is not easy to lower the head to look at the instrument, and dangerous driving is likely to occur; finally, for some motorcycle riding enthusiasts, restricted by the crowded traffic during the day, users mostly choose to initiate riding activities at night. When parking without external lighting equipment, directly using the headlight for lighting does not create a strong sense of atmosphere. Therefore, the convenience of existing motorcycle riding needs to be improved. Summary of the Invention

[0006] The present invention aims to provide a rearview mirror and a motorcycle with multiple lighting functions, which can effectively improve the convenience of riding.

[0007] To solve the above technical problems, the present invention provides the following technical solutions:

The light enters the Fresnel lens through the light guide bar for light concentration, so as to project a ground projection width indication lamp obliquely forward to assist the user in judging obstacles and passing through, which helps the user pass at a low speed and avoid scratching. Therefore, through the above lighting method, the convenience of riding can be effectively improved.

[0010] Optionally, a light guide plate is arranged inside the back shell, the light guide plate is parallel to the rearview lens and one end is located on one side of the rotating lamp board; an atmosphere lamp opening is formed on one side of the back shell close to the front of the motorcycle body, and a light-transmitting IML film sheet capable of pattern customization is arranged on the atmosphere lamp opening.

[0011] By adopting the above technical solution, when the user needs an atmosphere lighting scenario, under the premise of gear N (neutral), or the user actively selects the atmosphere lamp mode, neutral coasting, or display, enter the menu to select the atmosphere mode through the left and right buttons of the gear lever, and then rotate the rotating end of the servo motor controlled by the user's control line until the lamp beads on the rotating lamp board face the light guide plate. At this time, the lamp beads face the ground, and the light emitted by the lamp beads enters the light-transmitting IML film sheet through the light guide plate, so as to meet the personalized needs of the user's atmosphere lamp when parking, and further improve the convenience of riding by switching the lighting function.

[0012] Optionally, a prefabricated symbol printing position is arranged on the rearview lens, and a warning symbol is printed on the prefabricated symbol printing position and is located on one side of the rotating lamp board.

Moreover, during an emergency braking process, the brightness is adjusted to the maximum value to assist the rear double-flash function, enabling vehicles and pedestrians behind to notice the abnormality.

[0014] Optionally, the lamp beads adopt SMART-RGB lamp beads.

[0015] By adopting the above technical solution, it is possible to emit various color light sources while ensuring that the volume of the lamp beads is small enough.

[0016] Optionally, the receiver adopts an NXP LIN receiver, and the controller adopts an STM8 MCU controller.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0035] An embodiment of the present invention provides a rearview mirror with multiple lighting functions.

[0036] Reference Figure 1 And Figure 2 , the rearview mirror with multiple lighting functions includes a frame body 1, the frame body 1 is rotatably connected to the motorcycle body, and the top of the frame body 1 is rotatably connected to a back shell 2. A rearview lens 3 is fixedly connected to one side of the back shell 2 close to the rear of the motorcycle body.

[0037] Reference Figure 1 、 Figure 2 、 Figure 3 And Figure 4 , a PCBA board and a servo motor 4 are fixedly connected to the inner wall of the back shell 2 on the side close to the motorcycle body. A receiver 5 and a controller 6 are installed on the PCBA board. A Hall sensor 7 is installed on the servo motor 4, and a rotating lamp board 8 is fixedly connected to the rotating end of the servo motor 4. A plurality of lamp beads 9 are linearly and equidistantly installed on one side of the rotating lamp board 8. The controller 6 is electrically connected to the receiver 5, the servo motor 4, the Hall sensor 7, and the lamp beads 9 respectively.

[0038] Among them, the receiver 5 adopts an NXP LIN receiver, and the controller 6 adopts an STM8 MCU controller. The adoption of the above receiver 5 and controller 6 has a CAN / LIN communication function, which can effectively ensure the connection with the existing vehicle system.

[0039] When the rotating end of the servo motor 4 rotates, the Hall sensor 7 can detect the position and speed of the inner rotor of the servo motor 4, so as to achieve precise control of the orientation of the lamp beads 9 on the rotating lamp board 8. The direction of the motorcycle body's head is defined as the front, and the direction of the tail is defined as the rear. Under the rotation of the rotating end of the servo motor 4, the rotating lamp board 8 can rotate so that the lamp beads 9 face forward, face backward, and face the ground.

[0040] Among them, the lamp beads 9 adopt SMART-RGB lamp beads, and the number of lamp beads 9 is 10, which can emit various color light sources while ensuring a sufficiently small volume.

[0041] Reference Figure 3 , a light guide bar 10 is fixedly connected inside the back shell 2, and the light guide bar 10 is supported and fixed by a support block. One end of the light guide bar 10 faces the rotating lamp board 8, and the other end faces the ground. A ground projection width indication opening is formed at the bottom of the back shell 2, and the ground projection width indication opening is arranged along the length direction of the motorcycle body. A Fresnel lens 11 is fixedly connected to the end of the light guide bar 10 facing the ground, and the Fresnel lens 11 is located at the ground projection width indication opening.

[0042] Among them, the number of Fresnel lenses 11 can be one or more, and in the embodiment of the present application, it is two.

[0043] When the rotating end of the servo motor 4 rotates to make the lamp beads 9 on the rotating lamp board 8 face the light guide bar 10 (the lamp beads 9 face forward), light enters the Fresnel lens 11 through the light guide bar 10 for light concentration, so as to project vertical light obliquely forward, that is, project a ground projection width indication lamp obliquely forward, which can assist the user in judging the passage of obstacles.

[0044] Reference Figure 3 , a light guide plate 12 is fixedly connected inside the back shell 2, and the light guide plate 12 is supported and fixed by a support plate. The light guide plate 12 is parallel to the rear view lens 3, and one end of the light guide plate 12 is located on one side of the rotating lamp board 8. An ambient light opening is formed on the side of the back shell 2 close to the front of the motorcycle body, and a light-transmitting IML (In Molding Label) film 13 is fixedly connected to the ambient light opening, and patterns can be customized on the light-transmitting IML film 13.

[0045] The light-transmitting IML film 13 includes a hardened transparent film layer, a printed pattern layer, and a plastic layer arranged in sequence from outside to inside. Since the printed pattern layer is located between the hardened transparent film layer and the plastic layer, the ink of the printed pattern layer will not contact the air and will not be damaged, so the quality of the ambient light can be effectively guaranteed.

[0046] When the rotating end of the servo motor 4 rotates to make the lamp beads 9 on the rotating lamp board 8 face the light guide plate 12 (the lamp beads 9 face the ground), light enters the light-transmitting IML film 13 through the light guide plate 12, so as to meet the personalized needs of the user for the ambient light when parking.

[0047] The rear-view lens 3 adopts an electroplated mirror or a 3M RPM (Reflective Polarizing Material) semi-transparent membrane mirror. A prefabricated symbol printing position 14 is provided on the rear-view lens 3, and a warning symbol is printed on the prefabricated symbol printing position 14. The warning symbol can be an exclamation mark. The prefabricated symbol printing position 14 is located on one side of the rotating lamp panel 8.

[0048] When the rotating end of the servo motor 4 rotates to the position where the lamp beads 9 on the rotating lamp panel 8 face the prefabricated symbol printing position 14 (the lamp beads 9 face backward), light shines on the prefabricated symbol printing position 14, and the warning symbol is displayed on the rear-view lens 3, so that a warning light warning can be realized on the rear-view lens 3. The rear-view lens 3 can replace part of the functions of the instrument warning light, solve the problem that it is not easy to look down at the instrument in terms of motorcycle ergonomics, and avoid dangerous driving.

[0049] When driving at low speed, the user can turn on the position lamp at night through the control button, project vertical line light obliquely forward to assist the user in judging obstacles to pass, and at this time the lamp beads 9 face the ground. When parking, the user can turn on the ambient light at night through the control button, and at this time the lamp beads 9 face the ground. When driving at high speed, the user can turn on the warning light at night through the control button. Therefore, the convenience of riding can be effectively improved, and the riding safety and comfort can be guaranteed.

[0050] Specifically, due to the equipped LIN communication, the rear-view mirror needs to cooperate with the intelligent instrument panel. The intelligent instrument panel can output vehicle speed and mode signals externally. After LIN communication, it is processed by the controller 6 in the back shell 2. For example, it automatically switches to mode one (ambient light mode) at 0-20 KM / H, and automatically switches to mode three (warning light mode) when the vehicle speed is above 20 or when the vehicle speed drops rapidly and brakes emergently. The motorcycle handle shortcut keys can directly operate mode two (ground-projecting position lamp mode), or enter mode two through the menu to achieve automatic operation.

[0051] In the ambient light mode, under the premise of gear N (neutral gear), or when the user actively selects the ambient light mode, neutral gear coasting, and display, enter the menu to select the ambient mode through the left and right keys of the gear lever, and display the mode of the rear-view mirror light according to the LIN communication instruction. The following several modes are preset:

[0052] Fixed color display: When parked in gear N and the whole vehicle is powered on, 16-color ambient lights are preset through a preset program to adapt to the entertainment and display front-view scenarios that need to maintain silence.

[0053] Breathing light display: When parked in gear N and the whole vehicle is powered on, turn on and off the 1Hz breathing light display through a preset program, cooperate with the breathing headlight, music, etc. to achieve a mixed audio-visual display, and adapt to the entertainment and display front-view scenarios that need to be soothing.

[0054] In the ground-projecting width indicator light mode, the main function is to assist motorcycle users in passing through narrow areas, especially on roads where it is difficult to determine the width at night. It is called by long-pressing the button on the motorcycle instrument. After activation, the servo motor 4 quickly rotates until the lamp bead 9 faces the ground. It can also be set to turn on at night (the instrument's photosensitive sensor receives the signal, and the instrument processes it and transmits the LIN signal to the rearview mirror). In the automatic mode at night, it automatically turns off when the vehicle speed is greater than 15 km / h.

[0055] In the warning light mode, this function is mainly used to prompt motorcycle users during daily use, replacing some functions of the instrument warning light, solving the problem that it is not easy to look down at the instrument in terms of motorcycle ergonomics, resulting in dangerous driving and the inability to clearly see the instrument warning light when a fault occurs. Also, during sudden braking, the brightness is adjusted to the maximum value to assist the rear double-flash function, allowing vehicles and pedestrians behind to notice the abnormality.

[0056] This component mainly relies on the 3M patent RMP as the first choice. This film material can meet the regulatory reflection requirements and also ensure a certain rear transmittance to achieve the transmission of the liquid crystal screen or warning light.

[0057] Based on the same inventive concept, an embodiment of the present invention also provides a motorcycle.

[0058] The motorcycle includes: a motorcycle body and the above-mentioned rearview mirror. The motorcycle body has a power supply 15 and an intelligent instrument panel. The power supply 15 is electrically connected to the servo motor 4, the controller 6, and the lamp bead 9 respectively to supply power to the servo motor 4, the controller 6, and the lamp bead 9. The power supply 15 uses a 12V DC-DC power supply. The intelligent instrument panel is communicatively connected to the receiver 5.

[0059] As described above, the above embodiments are only used to introduce the technical solutions of the present invention in detail. However, the description of the above embodiments is only for helping to understand the method and its core idea of the present invention, and should not be construed as a limitation of the present invention. Those skilled in the art of this technology can easily think of changes or substitutions within the technical scope disclosed by the present invention, and all of them should be covered within the protection scope of the present invention.
