Description

Technical Field

[0001] This utility model relates to the technical field of motorcycle or electric vehicle parts, and in particular to a vertical backrest that is easy to connect. Background Technology

[0002] An upright backrest provides lumbar and back support for cyclists, reducing fatigue from long rides. At the same time, during emergency braking or sudden acceleration, the backrest can prevent cyclists from leaning back excessively, reducing the risk of injury.

[0003] Existing upright backrests are mainly injection molded or made by bending and welding steel pipes. However, they also have some obvious drawbacks. Injection molded backrests may be slightly insufficient in terms of strength and durability, while steel pipe welded backrests are relatively bulky, resulting in a poor customer experience.

[0004] Therefore, those skilled in the art are dedicated to developing an easy-to-connect vertical backrest that is not only simple in structure and has high support strength, but also facilitates rapid installation. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a vertical backrest that is easy to connect, which is not only simple in structure and has high support strength, but also facilitates quick installation.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] An easy-to-connect vertical backrest, including

[0008] Support assembly;

[0009] The backrest body has a mounting cavity, in which a first connecting plate is installed, and the bracket assembly is connected to the first connecting plate via a connecting assembly.

[0010] A padding assembly is mounted on the side wall of the backrest body.

[0011] The beneficial effects of adopting the above solution are: by using the bracket assembly and the backrest body, and by using the connecting assembly to connect the bracket assembly to the first connecting plate in the backrest body, the vertical backrest can be quickly connected and installed, eliminating the traditional welding or complex assembly methods, greatly simplifying the installation steps, reducing the installation difficulty and time cost, and improving the user's convenience.

[0012] The backrest body has a mounting cavity, and a first connecting plate is installed in the mounting cavity. The bracket assembly is connected to the first connecting plate through the connecting assembly, making the connection between the backrest body and the bracket assembly more secure. The padding assembly can effectively distribute and bear the pressure applied to the backrest by the rider during riding, thereby improving the support strength and stability of the backrest, avoiding deformation or damage to the backrest due to long-term riding or emergency braking, and extending the service life of the backrest.

[0013] Based on the above technical solution, the present invention can be further improved as follows.

[0014] Furthermore, the bracket assembly includes a first leg and a second leg, each of which has a connection hole at one end for connecting to the vehicle frame. The first leg and the second leg are connected at one end via a second connecting plate, and the second connecting plate is connected to the first connecting plate.

[0015] The beneficial effects of adopting the above-mentioned further solution are: setting the first and second legs to use multi-point support increases the support stability, and setting a connection hole at one end of the legs allows the bracket assembly to be firmly connected to the frame, which enhances the overall stability of the backrest and ensures that it will not loosen due to bumps or external forces during riding.

[0016] Furthermore, both the first and second legs are arc-shaped.

[0017] The beneficial effects of adopting the above-mentioned further solutions are: the curved feet allow the padding components to conform more closely to the curves of the human body, providing cyclists with a more natural and comfortable support effect and reducing fatigue caused by long-term riding.

[0018] Furthermore, extension plates are connected to both sides of the second connecting plate.

[0019] The beneficial effect of adopting the above-mentioned further solution is that by setting extension plates on both sides of the second connecting plate, the connection area is further expanded, the overall structural strength and stability of the bracket assembly are enhanced, and it can better withstand forces from different directions.

[0020] Furthermore, the connecting assembly includes a connecting post disposed on the second connecting plate and the extension plate, and a connecting screw passes through the first connecting plate and is connected to the connecting post.

[0021] The beneficial effects of adopting the above-mentioned further solution are: the connecting component adopts the structure of connecting column and connecting screw, and the screw passes through the first connecting plate and connects to the connecting column, realizing the quick connection and disassembly of the backrest body and the bracket assembly. It is not only easy to operate, but also the connection is firm and reliable, which greatly improves the efficiency of installation and maintenance.

[0022] Furthermore, the first connecting plate is connected to the side wall of the backrest body by locking screws.

[0023] The beneficial effect of adopting the above-mentioned further solution is that the locking screw can provide sufficient locking force to ensure a tight connection between the first connecting plate and the backrest body, thereby improving the reliability and durability of the backrest structure.

[0024] Furthermore, a shock-absorbing pad is also installed between the extension plate and the backrest body.

[0025] The beneficial effects of adopting the above-mentioned further solutions are: the shock-absorbing pads can protect the backrest body and support components from damage caused by frequent impacts and vibrations, reduce structural fatigue, and thus extend the service life of the backrest.

[0026] Furthermore, a backrest cover is installed on the side wall of the backrest body, and the backrest cover seals the mounting cavity.

[0027] The beneficial effects of adopting the above-mentioned further solution are: a backrest cover plate is installed on the side wall of the backrest body, which seals the mounting cavity and can effectively prevent dust, debris or moisture from entering the mounting cavity, protect the internal connecting components and the first connecting plate from pollution and corrosion, thereby extending the service life of the backrest.

[0028] Furthermore, a support frame is installed on the side wall of the backrest cover.

[0029] The beneficial effects of adopting the above-mentioned further solution are: the backrest cover is equipped with a support frame on the side wall, which can provide additional support for the backrest cover, enhance the overall structural strength and stability of the backrest, and enable it to better bear the rider's weight and external force and transmit them evenly.

[0030] Furthermore, the padding assembly is installed on the support frame.

[0031] The beneficial effects of adopting the above-mentioned further solution are: the padding assembly is installed on the support frame, which can ensure that the position and angle of the padding assembly are more in line with the curve of the human body, providing the rider with softer and more comfortable support, reducing fatigue caused by long-term riding, and also better distributing pressure to protect the rider's waist and back.
