Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and specifically refers to a motorcycle rearview mirror. Background Technology

[0002] Motorcycle rearview mirrors are a core safety component of motorcycles. They are mainly used to provide the driver with a view of the road conditions behind and to the sides of the vehicle while riding, helping the driver to keep abreast of information about surrounding vehicles, pedestrians and obstacles, and assisting in judging the safety of lane changes, turns and other operations, so as to avoid traffic accidents caused by blind spots.

[0003] Existing motorcycle rearview mirrors have significant drawbacks in their viewing angle adjustment mechanisms. Most mirrors can only be fine-tuned around a single axis, resulting in a narrow adjustment range and fixed adjustment points. This makes it impossible to flexibly adapt the viewing angle to the driver's height, posture, or driving scenario. Furthermore, the fixing methods are unstable; snap-on or friction-type structures are prone to loosening under road bumps or engine vibrations, causing viewing angle shifts and requiring frequent stops for adjustments. Some mirrors also suffer from the problem of relative rotation between the mirror body and the adjustment arm. Therefore, there is an urgent need for a motorcycle rearview mirror that offers flexible viewing angle adjustment, stable angle fixation, and prevents mirror body rotation. Utility Model Content

[0004] This invention solves the problems mentioned in the background art by using multiple adjustment rails on the frame, an adjustment arm with a universal ball joint, and a locking cover to achieve flexible positioning and stable fixation of the eyeglasses.

[0005] The purpose of this utility model is achieved as follows: a motorcycle rearview mirror, including a frame and a mirror body, further includes: The adjustment rails are configured in at least two along the extension direction of the frame, and each adjustment rail is provided with an arc-shaped guide groove and an internal thread adjacent to the arc-shaped guide groove; The adjusting arm has a mounting base at one end for connecting with the mirror body, and a universal ball joint at the other end. The universal ball joint can be selectively accommodated in the arc-shaped guide groove of any of the adjusting rail sections. The locking cover has an external thread and a pressure plate. The locking cover engages with the internal thread of the selected adjustment section through its external thread, so that the pressure plate can press the universal ball head into the corresponding arc-shaped guide groove.

[0006] The present invention is further configured such that the frame is an L-shaped rod structure, and the at least two adjustment rails are arranged at intervals along their long side.

[0007] The present invention is further configured such that the pressure plate has a hemispherical recess on the side facing the universal ball head.

[0008] The present invention is further configured such that the mounting base of the adjusting arm is a polygonal column, and a polygonal slot is provided at the corresponding position of the mirror body. The polygonal column and the polygonal slot are interlocked to restrict relative rotation between the mirror body and the adjusting arm.

[0009] The present invention is further provided that the locking cover has a tool interface at the end opposite to the pressure plate.

[0010] The present invention is further configured such that each of the adjusting rail sections also includes a engagement groove, and the outer periphery of the locking cover is provided with an anti-rotation protrusion that cooperates with the engagement groove. When the locking cover is screwed to the end of the internal thread, the anti-rotation protrusion is engaged in the engagement groove to restrict the locking cover from continuing to rotate.

[0011] The present invention is further configured such that the adjusting swing arm is an integrally injection-molded plastic component.

[0012] By adopting the above technical solution, the beneficial effects that this utility model can achieve are: 1. By cooperating with multiple adjustment rail sections and the universal ball joint, the universal ball joint can be selectively accommodated in any arc-shaped guide groove, realizing multi-position adjustment of the lens body and improving the flexibility of viewing angle adjustment.

[0013] 2. By screwing the external thread of the locking cover into the internal thread of the adjusting rail section, the pressure plate is driven to press the universal ball head into the arc-shaped guide groove, which enhances the stability of the angle fixation and improves the stability during use.

[0014] 3. By adjusting the mounting base of the swing arm and the corresponding structure of the mirror body, the relative rotation between the two is restricted, ensuring that the preset viewing angle does not deviate, thus improving the mirror body's angle-keeping performance.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-4 : Example 1: This embodiment provides a motorcycle rearview mirror, including a frame 1 and a mirror body 2, and further including: The adjustment rail section 3 is configured in at least two along the extension direction of the frame 1. Each adjustment rail section 3 is provided with an arc-shaped guide groove 4 and an internal thread 5 adjacent to the arc-shaped guide groove 4. The adjusting arm 6 has a mounting base 7 at one end for connecting with the mirror body 2, and a universal ball head 8 at the other end. The universal ball head 8 can be selectively accommodated in the arc-shaped guide groove 4 of any of the adjusting rail sections 3. The locking cover 9 is provided with an external thread 10 and a pressure plate 11. The locking cover 9 engages with the internal thread 5 of the selected adjustment section 3 through its external thread 10, so that the pressure plate 11 can press the universal ball head 8 into the corresponding arc-shaped guide groove 4.

[0018] The mirror frame 1 is used to fix the rearview mirror to the vehicle as a whole and maintain structural stability; its structure is mostly rod-shaped, but it can also be designed into other adaptable shapes according to the vehicle; one end of it can be connected to the vehicle handlebars by bolts, and the other end extends to the driver's field of vision area and is connected to the mirror body 2 through components such as the adjusting rail section 3, the adjusting arm 6 and the locking cover 9.

[0019] The mirror body 2 is used to allow the driver to observe the surrounding environment of the vehicle; it is composed of a lens and a housing, and the housing has a structure that is adapted to the mounting base 7 of the adjusting arm 6; the lens is mostly rectangular, elliptical or trapezoidal, and the fixed housing is adapted to the shape of the lens; it is connected to the adjusting rail section 3 of the mirror frame 1 through the adjusting arm 6, and is within the driver's side field of vision; it is connected to the mounting base 7 of the adjusting arm 6 through the adaptation structure on the fixed housing.

[0020] The adjustment section 3 is used to realize multi-position adjustment of the lens body 2 and to provide a fixed base for the locking cover 9; the structure includes an arc-shaped guide groove 4 and an adjacent internal thread 5; the arc-shaped guide groove 4 is an arc-shaped groove adapted to the universal ball head 8; at least two are arranged at intervals along the extension direction of the lens frame 1, distributed on the side of the lens frame 1 close to the driver's field of vision, and can be fixed in an integral manner with the lens frame 1.

[0021] The adjusting arm 6 is used to transmit adjusting actions to adjust the angle and position of the mirror body 2 and restrict the relative rotation of the mirror body 2. It has a rod-shaped structure with a mounting base 7 at one end and a universal ball joint 8 at the other end, which can be integrally formed. The main shape is long and narrow. The mounting base 7 is a block structure that can be fitted and connected with the shell of the mirror body 2. The universal ball joint 8 is spherical. It is located between the mirror body 2 and the adjusting rail section 3. One end is embedded in the fixed shell of the mirror body 2, and the other end is accommodated in the arc-shaped guide groove 4 of the adjusting rail section 3 through the universal ball joint 8. One end of it is fitted with the adapter structure of the mirror body 2 through the mounting base 7 and connected by fasteners such as bolts 17. The other end is movably connected to the arc-shaped guide groove 4 of the adjusting rail section 3 through the universal ball joint 8.

[0022] The mounting base 7 is used to limit the relative rotation between the two to keep the angle of the mirror body 2 stable; it is constructed as a protruding structure at one end of the adjusting arm 6, which is adapted to the housing adaptation structure of the mirror body 2; it is located at the end of the adjusting arm 6 away from the universal ball head 8, and directly docks with the housing of the mirror body 2 for fitting connection, and relies on shape matching to limit rotation.

[0023] The universal ball joint 8 is used to realize multi-angle rotation adjustment of the mirror body 2, and can maintain rotation capability in the locked state; it is constructed as a smooth spherical structure at one end of the adjusting arm 6, and the surface can withstand a certain clamping force and maintain rotation; the shape is a standard spherical shape that fits the arc guide groove 4; it is located at the end of the adjusting arm 6 away from the mounting base 7, and can be selectively accommodated in the arc guide groove 4 of any adjusting rail section 3; it is clamped between the arc guide groove 4 and the pressure plate 11, and can overcome friction to rotate in the locked state to realize angle adjustment.

[0024] The locking cover 9 provides a moderate clamping force, allowing the ball head to rotate while maintaining the adjusted angle. Its structure includes an external thread 10 and a pressure plate 11. The external thread 10 surrounds the outer circumference, and the pressure plate 11 is located at one end, forming a clamping space with the arc-shaped guide groove 4. The overall shape is cylindrical or frustum-shaped, with the pressure plate 11 being a circular plate. Positioned on the outside of the adjusting rail section 3, the pressure plate 11 and the arc-shaped guide groove 4 clamp the universal ball head 8 after the external thread 10 engages with the internal thread 5. The external thread 10 connects to the internal thread 5 of the adjusting rail section 3, forming a stable clamping force on the universal ball head 8, allowing rotation of the ball head without loosening it.

[0025] According to the above design, when it is necessary to adjust the rearview mirror angle, there is no need to loosen the locking cover 9; simply pushing or rotating the mirror body 2 will drive the adjustment arm 6 to move. The mirror body 2 fits into the mounting base 7 of the adjustment arm 6 through an adapter structure, which can synchronously drive the entire adjustment arm 6 to rotate. The universal ball joint 8 at the other end of the adjustment arm 6 is clamped between the arc-shaped guide groove 4 of the selected adjustment section 3 and the pressure plate 11 of the locking cover 9. Under the action of clamping force, it maintains the current angle and can overcome friction to move flexibly within the arc-shaped guide groove 4. Rotation allows for multi-angle adjustment of the mirror body 2. Since the matching structure of the arc-shaped guide groove 4 and the pressure plate 11 are both adapted to the spherical surface of the universal ball head 8, they can maintain stable contact during rotation, ensuring smooth adjustment. After adjustment, the universal ball head 8 remains in the new angular position under the clamping force and will not shift due to vibration. If it is necessary to change the adjustment position, the locking cover 9 can be loosened to remove the universal ball head 8 from the current adjustment section 3, place it into the arc-shaped guide groove 4 of another adjustment section 3, and then tighten the locking cover 9 to form a clamp.

[0026] The frame 1 is an L-shaped rod structure, with at least two adjustment rails 3 spaced apart along its long side. The purpose of this design is to achieve two key functions by setting the frame 1 to an L-shaped rod structure, utilizing its bent shape: firstly, the short side of the L-shape can be directly and securely connected to the motorcycle handlebars, ensuring the overall stability of the frame 1 when mounted on the vehicle and adapting to the conventional mounting space of the handlebars; secondly, the long side of the L-shape can extend towards the driver's side field of vision, providing reasonable and sufficient length space for the arrangement of the adjustment rails 3, avoiding the inability to space the adjustment rails 3 due to limited installation space. Furthermore, arranging at least two adjustment rails 3 spaced apart along the long side of the L-shape provides multiple mounting points for the universal ball joint 8 of the adjustment arm 6, meeting the driver's needs to adjust the position of the mirror body 2 according to height, posture, or driving scenario, ultimately obtaining a suitable field of vision; simultaneously, the simple shape of the L-shaped rod structure also reduces spatial interference between the frame 1 and other motorcycle components, ensuring overall ease of use.

[0027] The pressure plate 11 has a hemispherical recess 12 on the side facing the universal ball joint 8. The purpose of the above design is to optimize the contact fit between the pressure plate 11 and the universal ball joint 8 by setting a hemispherical recess 12 on the side of the pressure plate 11 facing the universal ball joint 8, so as to ensure a stable connection between the two and achieve flexible rotation. The hemispherical recess 12 has a concave spherical structure, and its curvature matches the outer spherical curvature of the universal ball head 8, allowing it to form a large-area close contact with the universal ball head 8. In terms of connection, the hemispherical recess 12, along with the locking cover 9, screws into the internal thread 5 of the adjusting rail section 3 via the external thread 10, and approaches the universal ball head 8. Finally, it and the arc-shaped guide groove 4 of the adjusting rail section 3 together wrap around the universal ball head 8. This not only transmits a stable clamping force through close contact, preventing the universal ball head 8 from shifting when the vehicle vibrates, but also allows the universal ball head 8 to rotate flexibly along the curved surface of the hemispherical recess 12 without loosening the locking cover 9, thus realizing convenient adjustment of the viewing angle of the mirror body 2. At the same time, it reduces local wear between the pressure plate 11 and the universal ball head 8, extending the service life of the components.

[0028] The mounting base 7 of the adjusting arm 6 is a polygonal column, and a polygonal slot 13 is provided at the corresponding position of the mirror body 2. The polygonal column and the polygonal slot 13 are interlocked to restrict relative rotation between the mirror body 2 and the adjusting arm 6. The purpose of the above design is to restrict relative rotation between the mirror body 2 and the adjusting arm 6 by setting the mounting base 7 of the adjusting arm 6 as a polygonal column and providing a matching polygonal slot 13 at the corresponding position of the mirror body 2. During installation, the polygonal column of the adjusting arm 6 is directly embedded into the polygonal slot 13 of the mirror body 2. Because the polygonal structure has no circular rotational degree of freedom, the possibility of the mirror body 2 rotating around the mounting base 7 can be eliminated structurally. This interlocking method does not require additional fasteners and can ensure that when the adjusting arm 6 drives the mirror body 2 to adjust the viewing angle, the two always maintain synchronous movement, avoiding the mirror body 2 rotating relative to the adjusting arm 6 during adjustment or when the vehicle is vibrating, thus ensuring that the driver's field of vision is always stable at the preset angle.

[0029] The locking cover 9 has a tool interface 14 at the end opposite to the pressure plate 11. The purpose of this design is to facilitate tightening or loosening of the locking cover 9 using tools, by providing the tool interface 14 at the end of the locking cover 9 opposite to the pressure plate 11, to adjust its clamping force on the universal ball joint 8 or to replace the adjustment section 3. The tool interface 14 can be adapted to common operating tools, such as being hexagonal to work with an internal hex wrench; or having a flathead or Phillips head slot to use with a flathead or Phillips head screwdriver; or being hexagonal to be engaged and rotated with a wrench. This design eliminates the need for manual tightening, especially when the locking cover 9 requires significant force to ensure stable clamping, or when slight corrosion after long-term use makes rotation difficult. The operation can be easily completed using appropriate tools, while avoiding hand slippage or surface wear that may occur with manual operation.

[0030] Each of the aforementioned adjusting rail sections 3 further includes a mating groove 15. The outer periphery of the locking cover 9 is provided with an anti-rotation protrusion 16 that mates with the mating groove 15. When the locking cover 9 is screwed to the end of the internal thread 5, the anti-rotation protrusion 16 engages with the mating groove 15 to restrict the locking cover 9 from continuing to rotate. The purpose of the above design is to prevent damage to components or abnormal clamping force due to excessive rotation when the locking cover 9 is screwed on by providing a mating groove 15 on each adjusting rail section 3 and providing a matching anti-rotation protrusion 16 on the outer periphery of the locking cover 9. When the operator uses a tool to rotate the locking cover 9, it gradually screws into the internal thread 5 of the adjusting rail section 3 until it reaches the end of the internal thread 5. At this point, the anti-rotation protrusion 16 on the outer periphery of the locking cover 9 will precisely engage with the engagement groove 15 of the adjusting rail section 3. The structural cooperation between the two restricts the locking cover 9 from continuing to rotate. This design can prevent the locking cover 9 from being over-screwed due to excessive operating force or misoperation, which would damage the tooth profile of the internal thread 5 and the external thread 10, or cause the pressure plate 11 to exert excessive clamping force on the universal ball joint 8, affecting the rotation flexibility. At the same time, it can also provide clear feedback for the locking cover 9 to be screwed into place, ensuring that the locking cover 9 is in the preset effective working position every time it is installed, and ensuring a stable and consistent clamping effect on the universal ball joint 8.

[0031] The adjusting arm 6 is a one-piece injection-molded plastic component. The purpose of this design is to simplify the production process of the adjusting arm 6 by using a one-piece injection molding process, while ensuring its structural integrity and reliability. One-piece injection molding allows the mounting base 7, the rod-shaped body, and the universal ball joint 8 of the adjusting arm 6 to form a seamless integrated structure, avoiding weak points in the connections caused by component splicing and reducing the risk of breakage or detachment during use. Furthermore, the plastic material itself has lightweight characteristics, reducing the overall weight of the rearview mirror and the load on the mounting part of the mirror frame 1. It also possesses moderate toughness, providing some cushioning when adjusting the angle of the mirror body 2 or when subjected to slight external forces, preventing damage caused by excessive rigidity. In addition, the plastic component also reduces material and processing costs during production, facilitating mass production.

[0032] In this embodiment, when using the rearview mirror, the short side of the L-shaped rod-shaped mirror frame 1 is first connected and fixed to the motorcycle handlebars. At least two adjustment rail sections 3, spaced apart along the long side of the mirror frame 1, provide different mounting points. When installing the adjustment arm 6, the polygonal column at one end engages with the polygonal slot 13 of the mirror body 2 to prevent relative rotation between the two. The universal ball joint 8 at the other end is selected and placed into the arc-shaped guide groove 4 of any adjustment rail section 3. Then, the locking cover 9 is screwed into the internal thread 5 of the adjustment rail section 3 through the external thread 10 until the anti-rotation protrusion 16 on the outer periphery of the locking cover 9 is engaged with the engagement groove 15 of the adjustment rail section 3, restricting the locking cover 9 from continuing to rotate. At this time, the pressure plate 11 at one end of the locking cover 9 clamps the universal ball joint 8 through the hemispherical recess 12 facing the universal ball joint 8 and the arc-shaped guide groove 4, maintaining a stable clamping force to prevent angular deviation while allowing the universal ball joint 8 to rotate directly. When the viewing angle needs to be adjusted, there is no need to loosen the locking cover 9. Simply push or rotate the mirror body 2 to drive the adjusting arm 6, so that the universal ball head 8 can rotate flexibly between the arc-shaped guide groove 4 and the recess 12 of the pressure plate 11 to achieve multi-angle adjustment. If the adjustment position needs to be changed, the locking cover 9 can be loosened with the tool interface 14 at the end of the locking cover 9 away from the pressure plate 11. The universal ball head 8 can be taken out and placed into other adjustment rail sections 3, and then the locking cover 9 can be tightened again to complete the fixation.

[0033] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
