[0002] At present, most motorcycle backrests (such as Harley) are made of sheet metal and round tubes and round bars that are bent and welded. Since such products are not suitable for large-scale processing, most of them are made manually through fixture positioning welding. Therefore, under manual operation, there will be inevitable deviations in the assembly of tubes and sheet metal. This processing deviation will cause inconsistent spacing between the two plates on the backrest bracket, resulting in installation problems such as being unable to clip the two plates into the grooves of the main structure, or difficulty in clipping the two plates into the grooves of the main structure.

[0023] The utility model provides an auxiliary installation structure. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the protection scope of the utility model.

[0024] See also Figure 1-Figure 3 The utility model provides an auxiliary installation structure, including a fixed rod body 1, a first insertion strip 11, a locking member 12, a rotating rod body 2, a second insertion strip 21, and a first limiting member 22; the first insertion strip 11 is fixedly connected to one end surface of the fixed rod body 1, and the first insertion strip 11 is used to be inserted into a first insertion hole 101 of a first plate body 10 on a backrest bracket 100; the locking member 12 is connected to the first insertion strip 11 and is used to fix the first insertion strip 11 in the first insertion hole 101; the fixed rod body 1 and the rotating rod body 2 can be extended or contracted, and the rotating rod body 2 is rotatably connected to the fixed rod body 1; the end surface of the rotating rod body 2 away from the fixed rod body 1 is fixedly connected to the second insertion strip 21, and the second insertion strip 21 is used to be inserted into the second insertion hole of the second plate body 20 on the backrest bracket 100, and the second insertion strip 21 is provided with the first limiting member 22, and the first limiting member 22 is used to abut against the outer wall of the second plate body 20.

[0025] See also Figure 4In the actual installation process, when the distance between the first plate 10 and the second plate 20 on the backrest bracket 100 is larger than the installation range of the groove on the main frame, it is necessary to shorten the distance between the first plate 10 and the second plate 20. The specific operation is as follows: twist the fixed rod 1 and the rotating rod 2 to shorten the length between the fixed rod 1 and the rotating rod 2; place the shortened fixed rod 1 and the rotating rod 2 between the first plate 10 and the second plate 20; insert the first insert 11 into the first plate 10 on the first plate 10. The first fixing member 22 is inserted into the second fixing member 21, and the first fixing member 22 is inserted into the second fixing member 21. The first fixing member 22 is inserted into the second fixing member 21, and the first fixing member 22 is inserted into the second fixing member 21. The first fixing member 22 is inserted into the second fixing member 21, and the first fixing member 22 is located on the outer wall of the second plate body 20 and abuts against the outer wall of the second plate body 20, so that the auxiliary mounting structure is fixed to the first plate body 1. 0 and the second plate body 20; then, by using the part of the second inserting strip 21 protruding from the second plate body 20, by twisting the second inserting strip 21, the rotating rod body 2 fixed to the second inserting strip 21 is driven to rotate synchronously, and under the action of the first limiter 22 and the locking member 12, the distance between the first plate body 10 and the second plate body 20 is gradually reduced until the lock buckle 30 on the first plate body 10 and the second plate body 20 is consistent with the range of the groove on the main frame, indicating that the distance between the first plate body 10 and the second plate body 20 is adjusted to the right position ; Then, taking advantage of the slight deformation of the backrest bracket 100, press the top of the backrest bracket 100 backward and downward until the lock buckles 30 on the first plate body 10 and the second plate body 20 are snapped into the grooves of the main structure, indicating that the backrest bracket 100 is installed in place; after the installation is completed, remove the locking piece 12 and the first limit piece 22, and then twist the rotating rod body 2 to shorten the length between the rotating rod body 2 and the fixed rod body 1, so as to facilitate the removal of the rotating rod body 2 and the fixed rod body 1 from the space between the first plate body 10 and the second plate body 20.

[0026] When the distance between the first plate 10 and the second plate 20 on the backrest bracket 100 is smaller than the installation range of the groove on the main frame, it is necessary to increase the distance between the first plate 10 and the second plate 20. The specific operation is similar to the above-mentioned operation of shortening the distance between the first plate 10 and the second plate 20, except that the direction of twisting and rotating the rod 2 is reversed, that is, when the distance between the first plate 10 and the second plate 20 is shortened by twisting and rotating the rod 2 clockwise, the distance between the first plate 10 and the second plate 20 is increased by twisting and rotating the rod 2 counterclockwise; conversely, when the distance between the first plate 10 and the second plate 20 is shortened by twisting and rotating the rod 2 counterclockwise, the distance between the first plate 10 and the second plate 20 is increased by twisting and rotating the rod 2 clockwise.

[0027] The above structure utilizes the material characteristics of the backrest bracket 100 composed of sheet metal (first plate body 10, second plate body 20) and round tube and round rod that can be slightly deformed, and then cooperates with the extendable or contractible rotating rod body 2 and fixed rod body 1, and fixes the rotating rod body 2 and the fixed rod body 1 in the socket on the sheet metal through the locking member 12 and the first limit member 22. The principle of the deformation of the backrest bracket 100 is utilized to realize the first plate body 10 and the second plate body 20 to approach or move away from each other, so as to adapt to the installation position of the groove on the main structure, which can compensate for the installation problem of the backrest bracket 100 caused by processing deviation.

[0028] See also Figure 2 In some embodiments, the fixed rod body 1 is a hollow structure, and an internal thread 14 is provided in its inner cavity, and a threaded portion 23 is provided on the end surface of the rotating rod body 2 facing the fixed rod body 1, and the threaded portion 23 is threadedly connected with the internal thread 14. Specifically, the interior of the fixed rod body 1 is set to be hollow, and the internal thread 14 is tapped into the inner cavity, and the threaded portion 23 is formed on the end surface of the rotating rod body 2, so that when the rotating rod body 2 is twisted, the threaded portion 23 moves left and right in the inner cavity of the fixed rod body 1, so that the overall length between the rotating rod body 2 and the fixed rod body 1 can be changed, that is, the fixed rod body 1 and the rotating rod body 2 can be extended or contracted.

[0029] See also Figure 3 In some embodiments, an external thread 111 is provided on the outer peripheral wall of the first inserting strip 11, and the locking member 12 is a nut, which is threadedly connected to the external thread 111. Similarly, the external thread 111 is formed on the first inserting strip 11, and the nut is threadedly connected to the first inserting strip 11 to fix the first inserting strip 11 and the fixing rod body 1 in the first insertion hole 101.

[0030] See also Figure 1 , Figure 3-Figure 5 In some embodiments, a second stopper 13 is further provided on the end surface of the fixed rod body 1, and the second stopper 13 and the first insertion strip 11 are provided on the same end surface of the fixed rod body 1; the first insertion hole 101 is a waist-shaped hole, and the second stopper 13 and the first insertion strip 11 are both located in the waist-shaped hole. Specifically, when the rotational force of the rotating rod body 2 is greater than the friction force between the nut and the first plate body 10, the rotating rod body 2 will still drive the fixed rod body 1 to rotate a certain angle when twisting. Therefore, by using the first insertion hole 101 as a waist-shaped hole, the second stopper 13 is inserted into one end of the waist-shaped hole, and the first insertion strip 11 is inserted into the other end of the waist-shaped hole, so as to ensure that when the rotating rod body 2 is twisted, the position of the first insertion strip 11 in the waist-shaped hole is unchanged, that is, to ensure that the fixed rod body 1 will not rotate with the rotation of the rotating rod body 2.

[0031] See also Figure 3In some embodiments, the second stopper 13 is a round head screw, which is threadedly connected to the end surface of the fixed rod body 1. In order to simplify the auxiliary installation structure, the second stopper 13 is set as a round head screw, and the round head screw is fixed to the end surface of the fixed rod body 1 by threaded connection, which is simple to process and convenient to assemble.

[0032] See also Figure 2 and Figure 3 In some embodiments, a mounting groove 211 is formed on the outer peripheral wall of the second inserting strip 21, and the first limiting member 22 is an open retaining ring, which is engaged in the mounting groove 211. The setting of the mounting groove 211 facilitates the open retaining ring to be directly engaged therein, thereby achieving the position limiting of the second plate body 20. Moreover, when the rod body 2 and the second inserting strip 21 are twisted and rotated, the open retaining ring is always located in the mounting groove 211, which will not hinder the rotation of the rotating rod body 2 and the second inserting strip 21, and can ensure the position limiting effect of the second plate body 20.

[0033] See also Figure 1 In some embodiments, the second inserting strip 21 is further provided with a twisting portion, which is used to drive the second inserting strip 21 and the rotating rod body 2 to rotate around the fixed rod body 1. The twisting portion is provided to increase the force arm when twisting the second inserting strip 21 and the rotating rod body 2, thereby saving effort.

[0034] See also Figure 2 and Figure 3 In some embodiments, the twisting portion is a through hole 24 extending in the radial direction of the second inserting strip 21, and the through hole 24 is used for inserting the twisting rod. Specifically, the twisting rod can be a common tool with a rod such as a screwdriver 25, a hexagonal wrench, a T-type wrench, etc. When in use, a part of the rod is inserted into the through hole 24, and the extended force arm of the rod part can be used to easily drive the rotating rod 2 to rotate through the second inserting strip 21, thereby realizing the change of the length of the rotating rod 2 and the fixed rod 1.

[0035] In summary, the utility model utilizes an extendable or contractible fixed rod body 1 and a rotating rod body 2 to change the length between the fixed rod body 1 and the rotating rod body 2, thereby facilitating the insertion of the first insertion strip 11 on the fixed rod body 1 and the second insertion strip 21 on the rotating rod body 2 into the insertion holes of the corresponding plates, and utilizes the locking member 12 and the first limiting member 22 to fix the auxiliary mounting structure on the first plate body 10 and the second plate body 20, and then utilizes the deformable backrest bracket 100 to make the locking buckles 30 on the first plate body 10 and the second plate body 20 adapt to the installation position of the groove on the main structure, which can compensate for the installation problem of the backrest bracket 100 caused by processing deviation.
