Description

Technical Field

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

[0002] Traditional bus rearview mirrors mostly adopt an outward-swinging structure, especially the right-side rearview mirror, which needs to extend outward through a long bracket to avoid the passenger door structure and allow the driver to see the blind spot near the right front wheel. However, this structure has many technical drawbacks in practical applications.

[0003] First, outward-swinging rearview mirrors are far from the driver's eyes. To ensure a wide field of vision, a highly curved convex mirror must be used, resulting in severe image distortion and a reduced image size. This makes it difficult for the driver to accurately judge the actual distance and speed of vehicles approaching from behind, posing a safety hazard. Second, the long support structure is prone to high-frequency shaking due to road bumps and engine vibrations during driving, causing the image in the mirror to jitter and severely affecting the observation effect. Third, traditional physical rearview mirrors have inherent blind spots, especially in the area below the side of the vehicle and the right-side door area. When pedestrians or non-motorized vehicles enter this area, it is difficult for the driver to notice them, which has become a major cause of accidents involving large vehicles making right turns. Summary of the Invention

[0004] The purpose of this invention is to provide a bus rearview mirror and a bus, so as to solve to some extent the technical problems of image distortion, screen shaking and large blind spots in the existing bus rearview mirrors.

[0005] This invention provides a rearview mirror for a passenger vehicle, comprising a housing, a main mirror, and side mirrors; The housing is fixed to the body of the bus; The main mirror and the two side mirrors are both installed at the opening of the housing. The two side mirrors are located on opposite sides of the main mirror. The main mirror is a reflective rearview mirror, and the side mirrors are side-stream media rearview mirrors. The housing is provided with a drive assembly, which is used to drive the two side mirrors to flip, so that the two side mirrors are folded or unfolded relative to the main mirror.

[0006] Furthermore, the main mirror includes a main mirror frame, and the side mirror includes a side mirror frame, the side mirror frame and the main mirror frame are rotatably connected by a hinge; The hinge includes a pivot and a bushing. The bushing is rotatably fitted onto the pivot. One of the pivot and the bushing is connected to the main mirror frame, and the other is connected to the side mirror frame.

[0007] Furthermore, the drive assembly includes two telescopic cylinders, each corresponding to one of the two side mirrors; One end of the telescopic cylinder is hinged to the housing, and the other end is hinged to the corresponding side mirror.

[0008] Furthermore, the telescopic cylinder is a dual-axis telescopic cylinder.

[0009] Furthermore, the side of each side mirror away from the main mirror is connected to the housing via a deformable shielding member, which can extend and retract as the side mirror is flipped to shield the gap between the side mirror and the housing.

[0010] Furthermore, the deformable shielding surface is an accordion-style structural component made of an elastomeric material.

[0011] Furthermore, it also includes a control module and a power module disposed within the housing; The control module is electrically connected to the power module. The control module is used to receive control signals from the bus and control the power module to work according to the control signals, so as to provide power to the drive assembly and drive the two side mirrors to flip.

[0012] Furthermore, the telescopic cylinder is a pneumatic cylinder, the power module is a solenoid valve assembly, the inlet of the solenoid valve assembly is connected to a compressed air source, and the outlet of the solenoid valve assembly is connected to the pneumatic cylinder; The control module is used to control the on / off state of the solenoid valve group to drive the cylinder to extend and retract.

[0013] Furthermore, the housing is connected to the bus body via a bracket, and the housing and the bracket are connected by a ball joint hinge, which has damping.

[0014] The present invention also provides a bus, including the bus rearview mirror described in any of the above claims.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The bus rearview mirror provided by this invention includes a housing, a main mirror, and two side mirrors. The housing is installed on the bus body, and the main mirror and two side mirrors are all embedded in the opening of the housing, with the two side mirrors respectively arranged on opposite sides of the main mirror. The main mirror has a traditional reflective rearview mirror structure, which conforms to the driver's usage habits of observing the road conditions behind, and can provide the driver with a direct rear view without delay, as a basic safety guarantee. The side mirrors adopt a side streaming media rearview mirror structure, which has a built-in image acquisition module that can collect wide-angle images of the side and rear of the vehicle and blind spots in real time, and transmit them synchronously to the display terminal in the driver's cab for the driver to view. This allows the driver to see an unobstructed and wider field of vision electronic image, effectively eliminating blind spots, and providing the driver with a clear field of vision even at night or in rainy or snowy weather.

[0016] Meanwhile, the two side mirrors can be flipped relative to the main mirror. A drive assembly is installed inside the housing, which drives the two side mirrors to complete the flipping action, allowing them to fold or unfold relative to the main mirror. The angle of the two side mirrors can be adjusted by the flipping operation, which can further expand the field of vision and eliminate blind spots. On the other hand, the two side mirrors can also be folded up when the vehicle is traveling at high speed, thereby reducing wind resistance.

[0017] The present invention also provides a bus, including the aforementioned bus rearview mirror, thus the bus also has the beneficial effects of a bus rearview mirror. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] The following reference Figures 1 to 3 This application describes a bus rearview mirror and a bus according to some embodiments.

[0027] This application provides a rearview mirror for a passenger vehicle, such as Figures 1 to 3 As shown, the bus rearview mirror includes a housing 2, a main mirror 3 and two side mirrors 4. The housing 2 is installed on the bus body and has an opening facing the rear of the vehicle. The main mirror 3 and the two side mirrors 4 are both embedded in the opening of the housing 2, and the two side mirrors 4 are respectively arranged on the left and right sides of the main mirror 3. The left and right directions correspond to the lateral direction of the bus body when it is in motion.

[0028] The main mirror 3 is a traditional reflective rearview mirror structure, which conforms to the driver's habit of observing the road conditions behind, and can provide the driver with a direct rear view without delay, as a basic safety guarantee; the side mirror 4 adopts a side streaming media rearview mirror structure, which has a built-in image acquisition module that can collect wide-angle images of the side and rear of the vehicle and blind spots in real time, and transmit them to the display terminal in the driver's cab for the driver to view. This allows the driver to see unobstructed and wider electronic images, effectively eliminating blind spots, and can provide the driver with a clear view even at night or in rainy or snowy weather.

[0029] Meanwhile, the two side mirrors 4 can be flipped relative to the main mirror 3. A drive assembly is installed inside the housing 2, which can drive the two side mirrors 4 to complete the flipping action, so that the two side mirrors 4 can be folded or unfolded relative to the main mirror 3. The angle of the two side mirrors 4 can be adjusted by means of the flipping operation, which can further expand the field of vision and eliminate blind spots; on the other hand, the two side mirrors 4 can also be folded up when the vehicle is traveling at high speed, thereby reducing wind resistance.

[0030] In one embodiment of this application, preferably, as Figure 2 and Figure 3 As shown, the main mirror 3 specifically includes a main mirror frame 31, with the glass of the main mirror 3 embedded and fixed inside the main mirror frame 31; the side mirror 4 correspondingly includes a side mirror frame 41, with the acquisition lens and display module of the side mirror 4 integrated and installed inside the side mirror frame 41. The side mirror frame 41 and the main mirror frame 31 are rotatably connected by a hinge 6. The hinge 6 includes a pivot and a bushing, with the bushing rotatably fitted outside the pivot. Of the pivot and bushing, one is fixedly connected to the side of the main mirror frame 31, and the other is correspondingly fixedly connected to the corresponding side of the side mirror frame 41, thereby providing stable rotational support for the rotation of the side mirror 4.

[0031] In this embodiment, preferably, as follows: Figure 3 As shown, the drive assembly includes two telescopic cylinders 7, which correspond one-to-one with two side mirrors 4. One end of the telescopic cylinder 7 is hinged to the housing 2, and the other end is hinged to the side mirror frame 41 of the corresponding side mirror 4. When the telescopic cylinder 7 performs telescopic movement, it can push the side mirror 4 to rotate around the pivot of the hinge 6, thereby realizing the folding and unfolding action. The structure is simple and reliable, and the driving force is stable.

[0032] Preferably, the telescopic cylinder 7 is a dual-axis telescopic cylinder; using a dual-axis telescopic cylinder can effectively improve the smoothness of movement and support rigidity of the side mirror 4 during the flipping process. The dual-axis telescopic cylinder has a dual-axis guiding structure, which can withstand a certain lateral load during telescopic movement, avoiding piston rod deflection caused by the weight of the side mirror 4 or driving vibration, thereby ensuring the movement accuracy and repeatability of the side mirror 4 during the folding and unfolding process.

[0033] In one embodiment of this application, preferably, as Figures 1 to 3 As shown, a deformable shielding member 5 is connected between the edge of each side mirror 4 away from the main mirror 3 and the opening sidewall of the housing 2. The deformable shielding member 5 can expand and contract synchronously with the flipping action of the side mirror 4, always shielding the gap formed between the side of the side mirror 4 and the opening of the housing 2 after flipping, so as to prevent rainwater and dust from entering the interior of the housing 2 through the gap during driving and causing corrosion and damage to the drive components and circuit modules inside the housing 2.

[0034] Preferably, the deformable shielding part 5 is an accordion-style structural part made of elastic rubber material, which has smooth extension and retraction, excellent sealing performance, can adapt to the frequent flipping action of the side mirror 4, and has a long service life.

[0035] In one embodiment of this application, preferably, as Figure 3 As shown, the housing 2 is also equipped with a control module 8 and a power module 9. The control module 8 and the power module 9 are electrically connected. The signal input terminal of the control module 8 is connected to the bus controller via a bus communication connection. It can receive control signals from the bus and control the power module 9 to work according to the corresponding control signals, so as to provide corresponding power to the drive components through the power module 9 and precisely drive the two side mirrors 4 to complete the corresponding flipping action.

[0036] In this embodiment, preferably, the telescopic cylinder 7 used to drive the side mirror 4 to flip is a cylinder, and the corresponding power module 9 is a solenoid valve group. The air inlet of the solenoid valve group is connected to the compressed air source on the bus, and the air outlet of the solenoid valve group is connected to the air inlet chamber of the cylinder. The control module 8 can control the extension and retraction of the cylinder by controlling the on and off states of different solenoid valves, thereby driving the side mirror 4 to complete the folding or unfolding action.

[0037] In one embodiment of this application, preferably, as Figure 1 As shown, the housing 2 is fixed to the bus body by the bracket 1. The housing 2 and the bracket 1 are connected by a damped ball joint hinge. The driver can easily adjust the overall angle of the rearview mirror according to his height and observation habits. After adjustment, the damped ball joint hinge can maintain the angle stable and will not shift due to driving vibration, thus adapting to the usage needs of different drivers.

[0038] This application also provides a bus, including the bus rearview mirror of any of the above embodiments.

[0039] In this embodiment, the bus includes a rearview mirror, and therefore the bus has all the beneficial effects of a rearview mirror, which will not be described in detail here.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
