Description

Technical Field

[0001] This utility model relates to the field of rearview mirror technology for two-wheeled vehicles, and in particular to a telescopic adjustable rearview mirror. Background Technology

[0002] Behind the booming development of the electric two-wheeler market, the design drawbacks of existing rearview mirrors are gradually becoming apparent. Currently, the vast majority of electric two-wheelers on the market use fixed rearview mirrors, the angle of which is difficult to adjust once installed, and cannot adapt to the different height differences and usage habits of different riders.

[0003] When electric two-wheelers are parked, the rearview mirrors are often loosened, detached, or even broken due to squeezing and collisions caused by crowded parking spaces. This not only requires owners to replace the rearview mirrors frequently, increasing operating costs, but more seriously, damaged rearview mirrors can cause problems such as shaking and blurred vision while riding, making it difficult for riders to clearly observe the road conditions behind them, greatly reducing driving safety and creating numerous hidden dangers for road traffic safety. Utility Model Content

[0004] In response to the shortcomings of the existing production technology, the applicant provides a reasonably structured telescopic adjustable rearview mirror that can adjust the length of the rearview mirror connecting rod and easily adjust the height of the rearview mirror, thus preventing damage to the rearview mirror caused by impact after parking at a low altitude.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A telescopic adjustable rearview mirror includes a telescopic tube and an outer tube nested together, with a telescopic positioning assembly between the telescopic tube and the outer tube. The telescopic positioning assembly includes:

[0007] The movable bubble point is elastically connected to the telescopic tube, and the telescopic path of the movable bubble point is always radial.

[0008] The positioning groove is formed on the outer tube, and at least two sets are set in the axial direction. The movable bubble point is embedded in one of the positioning grooves to achieve the limit.

[0009] As a further improvement to the above technical solution:

[0010] The telescopic tube has a stepped groove for accommodating the moving bubble point, and the tail end of the moving bubble point is set as a stepped structure and falls into the stepped groove.

[0011] The radial groove depth of the stepped groove is reserved to allow for the expansion and contraction of the movable bubble point.

[0012] The spring is filled in the stepped groove, and one end of the spring abuts against the end face of the movable bubble point.

[0013] A solid is set at the center line of the stepped groove, and the end of the spring away from the movable bubble point abuts against the solid.

[0014] The end of the active bubble point away from the telescopic tube is set as a round head.

[0015] The expansion and contraction points are symmetrically set on the horizontal plane in the direction of vehicle movement.

[0016] Each set of positioning slots is symmetrically arranged on the outer tube with the axis as the reference.

[0017] A limiting rib is provided between the telescopic tube and the outer tube, as well as a corresponding groove to accommodate the limiting rib.

[0018] It is a structure that can be continuously stretched and adjusted.

[0019] The beneficial effects of this utility model are as follows:

[0020] Adjustable rearview mirrors can precisely adapt to the needs of different users. For example, riders of different heights can adjust the mirror to a comfortable position that allows for easy observation of the road behind them. By extending and retracting the mirror, the area of ​​the road that can be observed can be increased, thus improving safety while riding.

[0021] When parking, in situations with limited space, the telescopic pole can be retracted by pressing the movable bubble, minimizing the outward extension distance of the rearview mirror. This effectively reduces the risk of scratching, deforming, or damaging it with adjacent vehicles. Even when temporarily parking in confined spaces, there's no need to worry about the rearview mirror breaking due to its protrusion.

[0022] This application utilizes a stepped structure as a positioning structure to limit the extension and retraction path of the movable bubble point, ensuring that the extension and retraction path of the movable bubble point is fixed and not prone to circumferential movement. The symmetrical arrangement of the movable bubble points ensures stable force during extension and retraction, and the spring connection between the two symmetrical movable bubble points ensures that the force on the two bubble points tends to be equal when the two movable bubble points are squeezed outward and retracted inward, making it less likely to produce asymmetrical movement with one side displaced and the other side not displaced, thus ensuring the reliability of the extension and retraction action.

[0023] The telescopic structure of this application is also provided with limiting ribs. The limiting ribs ensure that the telescopic tube and the outer tube are always coaxial and there is no circumferential movement. They can also be used to position the movable bubble point during assembly, so as to reduce the probability of the movable bubble point getting stuck in the positioning groove.

[0030] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0031] like Figures 1-3 As shown, the telescopic adjustable rearview mirror of this embodiment includes a telescopic tube 3 and an outer tube 2 nested together. A telescopic positioning assembly is provided between the telescopic tube 3 and the outer tube 2. The telescopic positioning assembly includes:

[0032] The movable bubble point 301 is elastically connected to the telescopic tube 3, and the telescopic path of the movable bubble point 301 is always radial.

[0033] Positioning grooves 201 are formed on the outer tube 2, and at least two sets are provided in the axial direction. The movable bubble point 301 is embedded in one set of positioning grooves 201 to achieve the limit.

[0034] The telescopic tube 3 has a stepped groove 302 for accommodating the movable bubble point 301. The tail end of the movable bubble point 301 is set as a stepped structure and falls into the stepped groove 302.

[0035] The radial groove depth of the stepped groove 302 is reserved with allowance for the expansion and contraction of the movable bubble point 301.

[0036] Spring 6 is filled in the stepped groove 302, and one end of spring 6 abuts against the end face of the movable bubble point 301.

[0037] A solid 303 is set at the center line of the stepped groove 302, and the end of the spring 6 away from the movable bubble point 301 abuts against the solid 303.

[0038] The end of the active bubble point 301 that is away from the telescopic tube 3 is set as a round head.

[0039] The expansion and contraction points are symmetrically set on the horizontal plane in the direction of vehicle movement.

[0040] Each set of positioning grooves 201 is symmetrically arranged on the outer tube 2 with the axis as the reference.

[0041] A limiting rib 4 is provided between the telescopic tube 3 and the outer tube 2, and a corresponding groove 5 is provided to accommodate the limiting rib 4.

[0042] It is a structure that can be continuously stretched and adjusted.

[0043] The specific structure and working principle of this utility model are as follows:

[0044] This utility model provides a rearview mirror 1 connection structure, which replaces the conventional rearview mirror 1 connecting rod with a telescopic connecting rod.

[0045] like Figure 1 and Figure 2 As shown, the telescopic connecting rod adopts a structure in which the outer tube 2 and the telescopic tube 3 are sleeved together. The outer tube 2 is coaxially sleeved on the outside of the telescopic tube 3. Several sets of positioning grooves 201 with different axial heights are opened on the outer tube 2. A set of movable bubble points 301 are set on the telescopic rod. The movable bubble points 301 are elastic structures. Through the elastic expansion and contraction of the movable bubble points 301, the movable bubble points 301 are embedded in the positioning grooves 201 with different axial heights, thereby realizing the length adjustment of the telescopic connecting rod.

[0046] The outer tube 2 and the telescopic tube 3 are coaxially arranged. In order to ensure that the two remain coaxial and prevent the assembly direction of the moving bubble point 301 from being incorrect, a limiting rib 4 is opened on the inner wall of the outer tube 2 and a sliding groove 5 is opened on the outer wall of the telescopic tube 3 so that the limiting rib 4 can be smoothly inserted along the sliding groove 5, thereby improving the stability of the structure.

[0047] As an alternative implementation, the limiting rib 4 can also be set on the outer wall of the telescopic tube 3, and the sliding groove 5 can be set on the inner wall of the outer tube 2, as long as the telescopic tube 3 and the outer tube 2 can fit together and achieve mutual limiting.

[0048] In one embodiment of this application, the active bubble point 301 is a pair of active buttons. The user adjusts the relative position between the outer tube 2 and the telescopic tube 3 through the active bubble point 301 to achieve the purpose of adjusting the height of the rearview mirror 1.

[0049] like Figure 2 As shown, a stepped groove 302 is formed inside the telescopic tube 3. The tail end of the movable bubble point 301 is a stepped end, and the protruding end of the movable bubble point 301 is a rounded end. The stepped end of the movable bubble point 301 falls exactly into the stepped groove 302, and the space within the stepped groove 302 provides the movable bubble point 301 with expansion and contraction allowance. The stepped structure of the stepped groove 302 is adapted to the stepped end of the movable bubble point 301, ensuring that the movable bubble point 301 can only extend axially and has an anti-detachment function.

[0050] To enable the movable bubble point 301 to have an elastic telescopic function, a spring 6 is installed in the stepped groove 302, which holds the movable bubble point 301 in place. When the movable bubble point 301 falls into the positioning groove 201, the spring 6 pushes the movable bubble point 301 tightly, locking it in the positioning groove 201. When telescopic movement is required, the movable bubble point 301 is pressed, causing it to retract into the outer tube 2. At this time, the spring 6 contracts, and the movable bubble point 301 can slide within the outer tube 2 along with the telescopic tube 3. When the movable bubble point 301 moves to a set of positioning grooves 201 again, the spring 6 resets, and the movable bubble point 301 pops out again, achieving the limit.

[0051] Since the movable bubble point 301 serves a limiting function, and given the tilted extension of the rearview mirror 1, high connection strength between the nested tube assemblies is particularly required, a unique bubble point structure with symmetrical sides and a restricted extension path is designed. When the rearview mirror 1 tilts and extends, the lower side experiences greater force. Therefore, the bubble points can be placed on both sides in the vertical direction, meaning that a set of movable bubble points 301 are both located in the forward direction of the electric vehicle, ensuring consistent force distribution at both movable bubble points 301. Therefore, the aforementioned limiting rib 4 is needed to assist in positioning, ensuring that the bubble point positions are within the same horizontal plane.

[0052] Figure 2 In one embodiment of this application, the stepped groove 302 is completely hollow inside, and a spring 6 abuts against the movable bubble points 301 at both ends.

[0053] As a preferred implementation method, such as Figure 3 As shown, a solid 303 is provided in the middle of the stepped groove 302, so that the end of the spring 6 away from the movable bubble point 301 abuts against the solid 303. In this way, when the spring 6 is pressed by an external force, the solid 303 serves as the force reference for the spring 6. This structure can ensure that the springs 6 on both sides have their own force references and will not form a situation of mutual force or unstable force.

[0054] In use, before driving, the user sits in the driver's seat and checks whether the positions of the two rearview mirrors 1 need adjustment. If adjustment is needed, the user pulls or pushes the telescopic tube 3. During the sliding process of the telescopic tube 3 inside the outer tube 2, when the relative position of the movable bubble point 301 of the telescopic tube 3 inside the outer tube 2 is adjusted to one of the positioning grooves 201, the movable bubble point 301 extends out of the positioning groove 201 to a limit. At this time, a certain amount of external force is required to make it slide again. If the user needs to continue to adjust the position of the telescopic tube 3 inside the outer tube 2, he only needs to press the movable bubble point 301 with a little force. The movable bubble point 301 disengages from the positioning groove 201, and the telescopic tube 3 can continue to move inside the outer tube 2.

[0055] For safety reasons, users should adjust the rearview mirror 1 to its optimal position before driving and try to avoid adjusting its position while driving.
