Description

Technical Field

[0001] This utility model relates to the field of rearview mirror technology, specifically a foldable motorcycle rearview mirror. Background Technology

[0002] Motorcycle rearview mirrors are located on the left and right sides of the front of the motorcycle. They help drivers understand the speed, distance, and type of vehicles approaching from behind, allowing them to detect potential dangers in advance and avoid rear-end collisions. When changing lanes or turning, drivers can use the rearview mirrors to check for oncoming vehicles, ensuring safe operation and reducing the risk of side collisions. Furthermore, the rearview mirrors expand the driver's field of vision, reducing blind spots and ensuring the safety of the driver while riding a motorcycle.

[0003] The patent document with publication number CN219044375U discloses a folding rearview mirror for motor vehicles. The folding rearview mirror is inserted into the annular groove by a set locking block and abuts against the locking ring, so as to achieve quick assembly and high stability when assembling the mounting bracket, bracket, turntable and drive housing.

[0004] The above technical solution uses a combination of annular washers, springs, and retaining rings to install and fix the column rod. This method requires the selection of a spring with a specific preload. If the spring is subjected to a large stress in the initial state, it will accelerate the fatigue failure of the spring. Conversely, if the preload is too small, it may not meet the working requirements for fixing the bracket, which may lead to failure and make the bracket prone to rotation. This method requires the selection of a spring with a specific preload according to the length of the column rod, which limits the applicability of the connector. Therefore, a foldable motorcycle rearview mirror is needed to solve the above technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a foldable motorcycle rearview mirror, which aims to solve the problems in the prior art.

[0006] To achieve the above objectives, one embodiment of the present invention provides a foldable motorcycle rearview mirror, comprising:

[0016] A bayonet groove is formed on the outer circumferential surface of the mounting shaft. An open retaining spring is engaged inside the bayonet groove, and the locking nut is located between the open retaining spring and the disc spring.

[0017] Preferably, the angle adjustment assembly includes an adjustment frustum, adjustment grooves, a rotating cylinder, and rotating protrusions. The adjustment frustum is connected to the mounting base, and the adjustment frustum and the mounting base are an integral structure. There are multiple adjustment grooves, which are evenly distributed on the top side of the adjustment frustum. Transition slopes are provided between the two ends of the multiple adjustment grooves and the adjustment frustum. The rotating cylinder is connected to the end of the cantilever bracket. There are multiple rotating protrusions, which are evenly connected to the bottom end of the rotating cylinder. Transition slopes are provided between the two ends of the multiple rotating protrusions and the rotating cylinder. The rotation slopes are in contact with the transition slopes, and the inclination directions of the rotation slopes and the transition slopes are parallel to each other.

[0018] Preferably, a limiting component is provided between the mounting base and the rotating cylinder. The limiting component is used to limit the rotation angle of the rotating cylinder. The limiting component includes an arc-shaped limiting groove and a limiting block. The arc-shaped limiting groove is disposed on the mounting base and is located at the same center position as the rotating shaft. The limiting block is connected to the outer peripheral surface of the rotating cylinder and corresponds to the position of the arc-shaped limiting groove. The limiting block can be inserted into the interior of the arc-shaped limiting groove.

[0019] Preferably, the mounting base is provided with a mounting cavity, the top side of the mounting cavity is provided with a sealing groove, and the inner wall of the sealing groove is provided with a sealing cover plate.

[0020] It also includes a rotating frustum, which is rotatably connected to the mounting base. The rotating frustum is provided with a rotating groove.

The appropriate number of disc springs can be selected according to the actual situation of use and multiple disc springs can be assembled together. This not only makes the assembly of the rearview mirror easier, but also provides double anti-loosening operation for the disc springs through the locking nut and open snap ring, ensuring the stability of the mounting shaft, rotating shaft, and cantilever bracket. The cantilever bracket will not rotate under the condition of no specific external force.

[0025] 2. The use of multiple disc springs not only allows for adjustment of the preload on the cantilever bracket, but also enables the disc springs to withstand larger loads. Furthermore, disc springs have higher strength and toughness compared to ordinary springs, thus ensuring a longer service life.

[0026] 3. The cantilever bracket can rotate the rearview mirror 45° relative to the mounting base, thereby enabling the rearview mirror to achieve a 45° radial folding function. Attached Figure Description

[0040] The present invention will now be further described with reference to the accompanying drawings.

[0041] Example 1: As Figures 1 to 9As shown, a foldable motorcycle rearview mirror includes a mounting base 10. A rotatable cantilever bracket 20 is provided on one side of the mounting base 10. A rearview mirror 30 is mounted on the cantilever bracket 20. An angle adjustment component is provided between the cantilever bracket 20 and the mounting base 10. The angle adjustment component is used to adjust the angle of the rearview mirror 30, thereby realizing the folding operation of the rearview mirror 30. A mounting plate 11 is provided on the mounting base 10. A mounting groove 12 is provided on the side of the mounting base 10 away from the cantilever bracket 20. An internally threaded sleeve 13 is provided in the middle of the mounting groove 12. The internally threaded sleeve 13 has a T-shaped cross-section and penetrates the mounting base 10. The inner wall of the internally threaded sleeve 13 is threadedly connected to a rotating shaft 40 connected to the cantilever bracket 20. The end of the shaft 40 away from the cantilever bracket 20 is connected to a mounting shaft 41. The axis of the mounting shaft 41 is on the same plane as the axis of the rotating shaft 40. The outer diameter of the mounting shaft 41 is smaller than the outer diameter of the rotating shaft 40. Multiple disc springs 42 are sleeved on the outer circumferential surface of the mounting shaft 41. One disc spring 42 at the end abuts against the internal threaded sleeve 13. A locking nut 43 is threadedly connected to the outer circumferential surface of the mounting shaft 41. The locking nut 43 contacts one disc spring 42 at the end. A bayonet groove 411 is provided on the outer circumferential surface of the mounting shaft 41. An open snap ring 44 is engaged inside the bayonet groove 411. The locking nut 43 is located in the middle of the open snap ring 44 and the disc spring 42. Multiple disc springs 42 are all located in the middle of the locking nut 43 and the internal threaded sleeve 13.

[0042] When installing the cantilever bracket 20, first connect the rotating shaft 40 to the internal threaded sleeve 13 and insert the mounting shaft 41 into the mounting groove 12. Then, select an appropriate number of disc springs 42 and fit them onto the outer surface of the mounting shaft 41, so that the uppermost disc spring 42 is in contact with the bottom end of the internal threaded sleeve 13. Then, connect the locking nut 43 to the outer surface of the mounting shaft 41, so that the locking nut 43 is in contact with the lowermost disc spring 42. During this process, the preload between the multiple disc springs 42 can be adjusted by adjusting the position of the locking nut 43. Then, connect the open snap ring 44 to the snap groove 411 to limit the locking nut 43. At this point, the installation of the cantilever bracket 20 is completed.

[0043] When mounting the mounting base 10 onto the motorcycle using the mounting plate 11, the mounting plate 11 is in contact with the vertical mounting surface on the motorcycle. After the mounting plate 11 is fixed onto the motorcycle, the angle between the mounting plate 11 and the cantilever bracket 20 is 45°. A schematic diagram after installing the cantilever bracket 20 is shown below. Figure 5 As shown.

[0044] It should be noted that the rotating shaft 40 and the cantilever bracket 20 are connected by screws and glue, making the rotating shaft 40 and the cantilever bracket 20 an integral structure, and making the connection between the rotating shaft 40 and the cantilever bracket 20 relatively firm.

[0045] like Figure 7 and Figure 8 As shown, the angle adjustment assembly includes an adjustment frustum 14 integrally formed with the mounting base 10 and a rotating cylinder 21 connected to the end of the cantilever bracket 20. The top side of the adjustment frustum 14 is provided with multiple adjustment grooves 141. Both ends of the multiple adjustment grooves 141 are provided with transition slopes between them and the adjustment frustum 14. Multiple rotating protrusions 22 are fixedly connected to the side of the rotating cylinder 21 away from the cantilever bracket 20. The number of rotating protrusions 22 corresponds to the number of adjustment grooves 141. The rotating protrusions 22 are located inside the adjustment grooves 141. The size of the rotating protrusions 22 is adapted to the adjustment grooves 141. The rotating protrusions 22 correspond one-to-one with the adjustment grooves 141. Both ends of the multiple rotating protrusions 22 are provided with rotating slopes between them and the rotating cylinder 21. The rotating slopes are in contact with the transition slopes, and the inclination directions of the rotating slopes and the transition slopes are parallel to each other.

[0046] When the angle of the rearview mirror 30 needs to be adjusted, the rearview mirror 30 is rotated manually by the cantilever bracket 20. At this time, the rotating cylinder 21 rotates relative to the adjusting platform 14. Under the action of the rotating protrusion 22 and the adjusting groove 141, the rotating cylinder 21 can be positioned. During this process, multiple disc springs 42 can increase the resistance between the rotating shaft 40 and the mounting shaft 41 during rotation, ensuring that the rotating cylinder 21 will not rotate after rotating to the appropriate angle without external force, thus stably fixing the rearview mirror 30 in the appropriate position. At this time, the cantilever bracket 20 can rotate 45° relative to the mounting base 10. After the motorcycle rearview mirror is installed, the state and rotation state of the rearview mirror 30 are as follows. Figure 2 As shown in the figure, the lower folding point and the upper folding point are marked on the figure.

[0047] It should be noted that the center of the internal threaded sleeve 13 and the center of the adjusting frustum 14 are on the same plane. A part of the internal threaded sleeve 13 is located inside the adjusting frustum 14, and the outer diameter of the internal threaded sleeve 13 is smaller than the inner diameter of the adjusting frustum 14. The center of the mounting shaft 41 and the center of the rotating cylinder 21 are on the same plane. After the mounting shaft 41 and the internal threaded sleeve 13 are connected, the center of the adjusting frustum 14 and the center of the rotating cylinder 21 are on the same plane, which allows the rotating cylinder 21 to rotate more smoothly. The coaxial center setting and the internal threaded sleeve 13 enhance the structural strength of the rotating shaft 40, greatly avoiding deformation of the rotating shaft 40.

[0048] like Figure 4 As shown, a limiting component is provided between the mounting base 10 and the rotating cylinder 21. The limiting component is used to limit the rotation angle of the rotating cylinder 21 to prevent the rotation angle of the rotating cylinder 21 from being too large. The limiting component includes an arc-shaped limiting groove 15 provided on the mounting base 10 and a limiting block 23 connected to the rotating cylinder 21. The limiting block 23 is positioned corresponding to the arc-shaped limiting groove 15. The center position of the arc-shaped limiting groove 15 is the same as the center position of the rotating shaft 40, so that the limiting block 23 can smoothly enter the interior of the arc-shaped limiting groove 15.

[0049] It should be noted that after the limiting block 23 fits tightly against the inner wall of the arc-shaped limiting groove 15, the rearview mirror 30 is folded at 45° on the longitudinal vertical plane.

[0050] like Figure 7 and Figure 9 As shown, the mounting base 10 is provided with a mounting cavity 16, and a sealing groove 161 is provided on the top side of the mounting cavity 16. A sealing cover plate 17 is installed on the inner wall of the sealing groove 161. The sealing cover plate 17 and the sealing groove 161 are locked together through a gap. A sealant is provided between the sealing cover plate 17 and the sealing groove 161. The sealing cover plate 17, the sealing groove 161 and the sealant make the waterproof performance between the sealing cover plate 17 and the mounting base 10 better, and prevent moisture and other substances from entering the interior of the mounting cavity 16.

[0051] It should be noted that when connecting the sealing cover plate 17 and the sealing groove 161, the connection is tightened by adding screws, so that the sealing cover plate 17 and the sealing groove 161 fit tightly, thereby making the sealing performance between the sealing cover plate 17 and the mounting base 10 better.

[0052] Example 2: Figure 9-12 As shown, a foldable motorcycle rearview mirror also includes a rotating platform 18 rotatably connected to a mounting base 10. The rotating platform 18 is provided with a rotating groove 181. A rotating cylinder 21 is connected to the rotating platform 18 through the rotating groove 181 and a rotating protrusion 22. The rotating platform 18 is used to drive the rotating cylinder 21 to rotate. A drive structure 19 is provided between the rotating platform 18 and the mounting base 10. The drive structure 19 is used to drive the rotating platform 18 to rotate.

[0053] When the angle of the rearview mirror 30 needs to be adjusted, the rotating frustum 18 is rotated by the drive structure 19. At this time, under the action of the rotating groove 181 and the rotating protrusion 22, the cantilever bracket 20 will drive the rearview mirror 30 to rotate, thereby adjusting the rearview mirror 30 to a suitable angle. Similarly, when the limiting block 23 is tightly fitted with the inner wall of the arc-shaped limiting groove 15, the rearview mirror 30 is folded at 45° on the longitudinal vertical plane.

[0054] It should be noted that a support cover is provided on the mounting base 10 to support the rotating frustum 18 and ensure its rotation. The bottom side of the support cover is provided with an opening. The diameter of the opening and the inner diameter of the rotating frustum 18 are both larger than the outer diameter of the internal threaded sleeve 13. The centers of the internal threaded sleeve 13, the opening, and the rotating frustum 18 are on the same plane, so that the center of the rotating cylinder 21 and the rotating frustum 18 are on the same plane, thereby ensuring that the rotating cylinder 21 can rotate smoothly.

[0055] like Figure 12 As shown, the drive structure 19 includes an end cover 191 connected to the sealing groove 161 and a transmission gear connected to the outer peripheral surface of the rotating frustum 18. A mounting cover 192 is installed on the bottom side of the end cover 191. A drive motor 193 is installed inside the mounting cover 192. A worm gear meshing with the transmission gear is provided inside the mounting cover 192. The drive motor 193 drives the worm gear to rotate through a transmission component such as a bevel gear, thereby enabling the rotating frustum 18 to rotate through a series of transmissions.

[0056] The end cap 191 and the sealing groove 161 are locked together through a gap. A sealant is provided between the end cap 191 and the sealing groove 161. The end cap 191, the sealing groove 161 and the sealant make the waterproof between the end cap 191 and the mounting base 10 better, preventing water vapor and other substances from entering the mounting cavity 16.

[0057] It should be noted that the end cap 191 and the sealing cover 17 are compatible in size and dimensions, and the end cap 191 and the sealing cover 17 can be installed interchangeably. Furthermore, the transmission components such as the transmission gear, worm gear, and bevel gear are existing mature technologies.

[0058] like Figure 10 and Figure 11 As shown, a controller module 50 is provided on one side of the mounting base 10. The controller module 50 is electrically connected to the drive motor 193 and connected to the main controller of the motorcycle, so that the drive motor 193 can be controlled to work through the controller module 50.

[0059] It should be noted that the controller module 50 is potted to provide waterproofing.

[0060] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
