[0002] The rearview mirror rod refers to a rod-shaped element that supports and installs the rearview mirror, wherein the other end of the mirror rod is detachably mounted to the vehicle body. A rod-type rearview mirror is installed on an electric bicycle, and the rearview mirror can mainly be used to observe vehicles coming from behind and traffic conditions on the rear side. In order to reduce the production cost of the rearview mirror, a lightweight mirror rod with the same supporting effect is used, and a hollow mirror rod is often used as the supporting part of the lightweight rearview mirror.

[0003] When the current rearview mirror rod is installed with the mounting threaded hole on the electric bicycle, a threaded column is generally welded on the mirror rod and threaded into the mounting threaded hole. However, the mounting threaded holes of electric bicycles of different brands have different sizes, and some are positive and some are negative. Therefore, the applicability of the mirror rod with the welded threaded column is affected to a certain extent. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a lightweight rearview mirror rod which can overcome the above problems or at least partially solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A lightweight rearview mirror rod comprises: a rod body and a connecting ball, wherein the connecting ball is fixed at one end of the rod body, and further comprises: a mounting plate fixedly connected to the end of the rod body away from the connecting ball; a connecting column arranged on the mounting plate; a fixing ring fixedly arranged on the lower side of the connecting column; a plurality of extrusion sheets fixedly connected to the lower side of the connecting column at equal intervals around the circumference; and an extrusion assembly arranged on the connecting column, wherein the extrusion assembly matches the extrusion sheet.

[0007] In order to facilitate the extrusion of the extrusion sheet, preferably, the extrusion assembly includes a bolt rotated on a connecting column, and sliding grooves are symmetrically opened in the connecting column. A sliding rod is slidably arranged between two of the sliding grooves, and the sliding rod is threadedly connected to the bolt, and a conical surface matching the extrusion sheet is arranged on the outer side of the sliding rod.

[0008] Preferably, a cross groove is provided on the upper side of the bolt.

[0009] In order to improve the friction between the extrusion sheet and the mounting thread groove, a rubber block is further fixedly connected to the extrusion sheet.

[0010] In order to facilitate the adjustment of the rod body, further, two limit rings are fixedly connected to the connecting column, a rotating ring is rotatably arranged between the two limit rings, a rubber friction ring matching the rotating ring is fixedly connected to the connecting column, and the mounting plate is fixedly connected to the rotating ring.

[0011] In order to facilitate the sealing between the connecting column and the upper side of the mounting thread groove, further, a retaining ring is fixedly connected to the lower side of the connecting column, and a rubber ring matching the extrusion sheet is fixedly connected to the inner side of the retaining ring.

[0012] Compared with the prior art, the utility model provides a lightweight rearview mirror rod, which has the following beneficial effects:

[0013] 1. The lightweight rearview mirror rod is manufactured by inserting a plurality of extrusion sheets into the mounting thread groove of the electric bicycle and pressing them downward, and rotating the bolt by an external wrench or screwdriver. The rotation of the bolt drives the sliding rod to move downward, and at this time, the extrusion sheet is squeezed by the conical surface, so that the rubber block fits with the thread teeth in the mounting thread groove, so that the rubber block is deformed and cooperates with the thread teeth in the mounting thread groove to provide a certain friction force to the connecting column. The extrusion-fitting installation method is adopted, and it can be applicable to electric vehicles with mounting thread grooves of various sizes, thereby effectively improving the applicability of the mirror rod and simplifying the installation.

[0014] 2. The lightweight rearview mirror rod cooperates with the rubber friction ring to enable the rotating ring to rotate, thereby adjusting the direction of the rod body. At the same time, the rubber friction ring can provide a certain resistance to the rotating ring to limit it and prevent it from shaking.

[0015] 3. The lightweight rearview mirror rod is deformed by squeezing the rubber ring through the extrusion sheet, thereby sealing the connection column and the upper side of the electric bicycle mounting thread groove to prevent rainwater from entering the mounting thread groove.

[0016] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model installs the mirror rod by adopting an extrusion-fit installation method, which can be suitable for electric vehicles with various sizes of mounting thread grooves, thereby effectively improving the applicability of the mirror rod and simplifying the installation.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1: Reference Figure 1-Figure 4 The lightweight rearview mirror rod comprises: a rod body 1 and a connecting ball 101, wherein the connecting ball 101 is fixed at one end of the rod body 1, and further comprises: a mounting plate 102, which is fixedly connected to the end of the rod body 1 away from the connecting ball 101; a connecting column 2, which is arranged on the mounting plate 102; a fixing ring 3, which is fixedly arranged on the lower side of the connecting column 2; a plurality of extrusion sheets 301, which are fixedly connected to the lower side of the connecting column 2 at equal intervals in a circle; and an extrusion assembly, which is arranged on the connecting column 2, and the extrusion assembly matches the extrusion sheet 301.

[0024] The extrusion assembly includes a bolt 201 that rotates on the connecting column 2, and a sliding groove 202 is symmetrically opened in the connecting column 2. A sliding rod 203 is slidably arranged between the two sliding grooves 202, and the sliding rod 203 is threadedly connected to the bolt 201. A conical surface 204 matching the extrusion sheet 301 is arranged on the outer side of the sliding rod 203.

[0025] A cross groove 207 is provided on the upper side of the bolt 201 .

[0026] A rubber block 302 is fixedly connected to the extrusion sheet 301 .

[0027] When installing the mirror rod of the rearview mirror, multiple extrusion sheets 301 are inserted into the installation thread groove of the electric bicycle and pressed downward, and the bolt 201 is turned by an external wrench or screwdriver. The bolt 201 rotates to drive the sliding rod 203 to move downward. At this time, the extrusion sheet 301 is squeezed by the conical surface 204, so that the rubber block 302 fits with the thread teeth in the installation thread groove, so that the rubber block 302 is deformed and cooperates with the thread teeth in the installation thread groove to provide a certain friction force to the connecting column 2. The extrusion-fit installation method can be applicable to electric vehicles with various sizes of installation thread grooves, thereby effectively improving the applicability of the mirror rod and simplifying the installation.

[0028] The rod body 1 adopts a hollow rod structure to achieve its lightness.

[0029] Example 2: Reference Figure 1-Figure 4 The lightweight rearview mirror rod is basically the same as that of Example 1. Furthermore, two limit rings 205 are fixedly connected to the connecting column 2, a rotating ring 103 is rotatably arranged between the two limit rings 205, a rubber friction ring 206 matching the rotating ring 103 is fixedly connected to the connecting column 2, and the mounting plate 102 is fixedly connected to the rotating ring 103.

[0030] A retaining ring 303 is fixedly connected to the lower side of the connecting column 2 , and a rubber ring 304 matching the extrusion sheet 301 is fixedly connected to the inner side of the retaining ring 303 .

[0031] The rotating ring 103 cooperates with the rubber friction ring 206 to enable the rotating ring 103 to rotate, thereby adjusting the direction of the rod body 1. At the same time, the rubber friction ring 206 can provide a certain resistance to the rotating ring 103 to limit its position and prevent it from shaking.

[0032] When the extrusion sheet 301 is squeezed by the conical surface 204, the extrusion sheet 301 squeezes the rubber ring 304 to deform it, thereby sealing the connection column 2 and the upper side of the electric bicycle mounting thread groove to prevent rainwater from entering the mounting thread groove.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
