Description

bicycle rear view device

technical field

The utility model relates to a bicycle accessory, in particular to a rear view device which can be installed on a bicycle handle tube and is equipped with a rear view mirror.

Background technique

In order to improve the riding safety of bicycles, existing manufacturers design special rearview mirrors on the handle pipes of bicycles, which can be installed on the outer peripheral wall of the handle pipes, or connected in the pipe body at the end of the handle pipes, as the inventor The authorized announcement number of the created application is the Taiwan utility model patent of TWM453635U, which discloses a grip bundle cover that can be connected with an extension piece, and the extension piece can be mutually locked with a bundle cover by a bolt, and at the same time, the The grip is locked on a handle tube. Although the end of the extension piece can be locked and connected to a rearview mirror by the locking piece, the rearview mirror cannot be adjusted freely. The locking piece must be unscrewed first. The angle of the rearview mirror can be adjusted. After the adjustment, the rearview mirror must be locked again, so the adjustment of the rearview mirror is more inconvenient, and there is only a single-dimensional rotation adjustment function, which is difficult to satisfy the rider's viewing angle of the rearview mirror. The adjustment requirements, coupled with the overall structural design, lead to the fact that the extension can only be extended towards the front of the rider, so that the rearview mirror cannot be extended towards the side of the rider. Therefore, in the riding state, the riding The rider's body or arms can easily block the viewing angle of the rearview mirror, making it difficult for the rider to effectively or fully grasp the rear road conditions.

The inventor subsequently also created a utility model patent in Taiwan, China, whose application authorization notification number is TWM611308U, which discloses a mirror frame structure of a bicycle rearview mirror, including a mirror frame, one end of which can be installed in the end of a handle pipe, The other end is formed with a socket hole, which can cooperate with a lock to lock a clip to the socket hole; one end of an upper mirror frame has a ball connected to the clip in a spherical shape, and the other end is pivotally connected to a rearview mirror. The rearview mirror can be pivoted in a certain angle range by the above-mentioned pivot joint structure, and has the functions of rotation and deflection by the above-mentioned spherical connection structure.

Although the mirror frame structure has two joint designs of different shapes, so that the rearview mirror has more variable position and angle adjustment functions, there are still some imperfections. For example, the lower mirror frame is designed to install In the end of the handle tube instead of being directly tied and locked to the handle tube, the fastening effect is poor and loosening is likely to occur.

The mirror frame structure, especially the assembly structure of the upper mirror frame and the lower mirror frame, can only be extended toward the rider's front, so there is also the disadvantage that the rearview mirror cannot be extended toward the rider's side. Although the rearview mirror can be properly pivoted to the left or right by utilizing the above-mentioned pivoting structure, its extended position is still insufficient, and the viewing angle of the rearview mirror is still easily blocked by the rider's body or arms.

Although the spectacle frame structure is designed with the above-mentioned pivot joint and spherical connection structure, which can provide more variable position and angle adjustment functions, it will also increase the complexity of the adjustment, and the operation is not simple enough and does not meet the requirements of humanization. In addition, even with the above-mentioned pivot joint and spherical connection structure, the rearview mirror cannot be folded and placed beside the lower mirror frame, resulting in a larger overall volume of the mirror frame structure, requiring less space for product storage and packaging. Larger, so its storage packaging and shipping costs are higher.

The mirror frame structure has both the above-mentioned pivot joint and spherical connection structure, which will also increase the number of integral components, thereby increasing the manufacturing and assembly costs.

Accordingly, the technical content disclosed in the above-mentioned patent documents still has many shortcomings or imperfections, and it is really necessary to improve them.

Utility model content

The technical problem to be solved by the utility model is: to provide a bicycle rear view device, which solves the problem that the rider's body or arm easily blocks the viewing angle of the rear view mirror in the existing technical solutions, making it difficult for the rider to effectively or completely grasp the rear view device. The rear road conditions, and the disadvantages of inconvenient use and adjustment.

The technical means of the utility model is: to provide a rear view device for a bicycle, including a mirror frame and a rearview mirror; the mirror frame further includes a C-shaped tie ring, which is used to tie the handle tube of a bicycle; The bracket has a connected base and an extension, the base can be locked to the C-shaped tie ring by a fastener, and the C-shaped tie ring is fastened to the handle tube, the extension faces from the base to The handle pipe extends outside and has a hole at the outside end; a bushing with a ball socket can be installed in the hole and fixed by a pressing bolt. A connecting portion protrudes from one side of the back side of the rearview mirror, and the connecting portion forms a ball joint, which can be spherically connected in the ball socket of the bushing, so that the rearview mirror has the functions of rotation and swing.

In the rear view device provided by the utility model, since the mirror frame is fastened to the handle tube by means of a C-shaped beam ring, the assembly firmness of the mirror frame can be ensured and loosening of the mirror frame can be avoided.

The base of the mirror frame of the utility model is installed behind the C-shaped beam ring, and by using the special extension structure and angle design of the extension part, the rearview mirror can be located just in front of and above the side of the rider, so as to ensure the The rearview mirror has a better viewing angle and will not be blocked by the rider's own body or arms, thereby improving the safety of riding.

The rear view device of the utility model adopts a single joint design, which can simplify the structure, so the number of components is small, which can reduce the cost of manufacturing and assembly, and the joint adopts a spherical structure, which has both rotation and deflection adjustment functions, so that the rear view device The mirror has a variety of adjustment functions in three dimensions, and the rider can easily and quickly adjust the rearview mirror to the desired position and angle of view, so the operation is in line with the humanized design.
