Technical Field

[0001] This utility model relates to a motorcycle rearview mirror, and in particular to a structure of a rearview mirror rod. Background Technology

[0002] Rearview mirrors are widely used in various vehicles to facilitate drivers' observation of the rear view and improve driving safety. The rearview mirror is connected to the vehicle via a mirror rod, which, in addition to its connecting function, also allows for position adjustment of the mirror or vehicle, facilitating the adjustment of the rearview mirror to the desired angle for a clear reflection of the rear view. Existing connection structures between mirror rods and rearview mirrors are relatively complex, requiring numerous components. This not only makes installation cumbersome but also demands high precision, resulting in high manufacturing and maintenance costs. Utility Model Content

[0003] The purpose of this invention is to provide a rearview mirror rod connection structure that is simple in structure and easy to adjust, so as to reduce structural complexity and thus reduce production costs.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0021] This utility model proposes a rearview mirror rod connection structure.

[0022] The rearview mirror rod connection structure of this embodiment includes a mirror rod 1 and a connecting rod 2 with a ball head 3 at one end; the top end of the mirror rod is provided with a connecting through hole 11, one end of the connecting through hole is a limiting end and the other end is a positioning end; the diameter from the middle of the connecting through hole to the limiting end is greater than the diameter of the ball head, the diameter of the positioning end of the connecting through hole is greater than the diameter of the connecting rod and less than the diameter of the ball head, and there is a limiting block 4 that is detachably fixed to the limiting end. The inner side of the positioning end of the connecting through hole and the inner side of the limiting block are respectively provided with spherical surfaces that cooperate with the ball head.

[0023] like Figure 1-4 As shown, the bottom end of the mirror rod is installed on the vehicle, and the top end of the mirror rod is connected to the connecting rod, which in turn is connected to the rearview mirror. Thus, the rearview mirror is installed on the vehicle via the mirror rod. The top end of the mirror rod has a connecting through hole with different diameters at both ends; the larger end is the limiting end, and the smaller end is the positioning end. During production and installation, the end of the connecting rod without the ball head is inserted into the limiting end of the connecting through hole and passes through the positioning end until the ball head enters the middle of the connecting through hole and abuts against the positioning end. Then, the limiting block is installed at the limiting end of the connecting through hole. The spherical surface on the inner side of the positioning end and the limiting block clamp the ball head from both sides through the spherical surface, allowing the connecting rod and the rearview mirror on it to adjust their angle by rotating the ball head.

[0024] The rearview mirror rod connection structure described above allows the spherical surface to be directly set on the inner wall of the through hole at the positioning end of the connecting through hole. However, its processing difficulty and precision requirements are relatively high. Therefore, it can be done as follows: Figure 2 , 3 As shown, a positioning block 5 is installed inside the positioning end of the connecting through hole 11. The positioning block has a spherical surface that contacts the ball head 3, and a positioning hole 51 for the connecting rod 2 to pass through is provided on the spherical surface. This ensures the stability of the spherical surface rotation by positioning the spherical surface on the positioning block. At the same time, this structure can reduce the processing difficulty and precision requirements. During installation, the positioning block only needs to be put on the connecting rod and then installed on the mirror rod, which will not generate too much additional assembly work. For ball heads of different diameters, different positioning blocks can be easily selected and installed on the mirror rod, thereby improving the applicability of the mirror rod. In addition, the inner wall of the positioning end of the connecting through hole 11 has a protruding positioning ring 12, and the positioning block 5 has a positioning groove 52 that abuts against the positioning ring. This positions and limits the positioning block axially without the need for other parts to fix it, which can effectively reduce the ease of assembly and disassembly. Furthermore, the positioning block 5 is made of a deformable material, such as a flexible plastic that can provide soft support, so that the ball head can compress the positioning block to a certain extent when rotating, making it easier to rotate, and can be more stably positioned in the required position by utilizing the rebound of the positioning block after rotating into place.

[0025] The rearview mirror rod connection structure described above allows the limiting block 4 to be fixed to the connecting through hole 11 of the mirror rod by screws, or it can be directly fixed to the connecting through hole 11 by interference fit. This structure is simpler and easier and faster to assemble and disassemble. In addition, the limiting block 4 and the connecting through hole 11 can be provided with matching threads. The threaded connection not only retains the advantage of simple structure, but also improves connection strength and working stability. Moreover, by adjusting the threads, the pressure of the limiting block pressing on the ball head can be adjusted, thereby adjusting the tightness of the ball head. This ensures the positioning accuracy of the ball head and makes it easier to adjust the connecting rod and the rearview mirror. The outer side of the limiting block 4 is also provided with a hexagonal groove 41 or a cross groove, which allows the user to easily adjust the limiting block with a hex wrench or screwdriver.

[0026] The rearview mirror rod connection structure described above has a bottom end of the mirror rod 1 mounted on the vehicle via a seat rod 6. The top end of the seat rod has a connecting plate 61, and the bottom end of the mirror rod has rotating plates 13 extending to both sides of the connecting plate. The bottom end of the rotating plates is semi-circular to facilitate rotation. Simultaneously, the connecting plate has recessed gasket grooves 62 on both sides, and two gaskets 7 are respectively installed in the gasket grooves on both sides and contact the two rotating plates. Furthermore, the rotating plates and the connecting plate have coaxially arranged through holes. Bolts 8 pass through all the through holes and are screwed onto nuts 9, thereby connecting the mirror rod and the seat rod. The mirror rod can also rotate relative to the seat rod to adjust the angle of the rearview mirror. To avoid excessively high connection strength between the rotating plates and the connecting plates, making relative rotation difficult, the following can be used... Figure 4 As shown, the rotating plate 13 opposite to the screw head of the bolt 8 is provided with a recessed mounting groove 14. The mounting groove is provided with an elastic plastic ring 10, which can compress the plastic ring to a certain extent when the rotating plate rotates, thereby improving the smoothness of rotation. After rotating to the position, the plastic ring can tighten the bolt through its elasticity, thereby ensuring the connection strength and preventing the mirror rod from rotating accidentally.

[0027] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
