[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] A multi-functional modular rear armrest, such as Figures 1 to 10 As shown, the handrail body 1 includes a lower surface of the handrail body 1 with a receiving groove 4. The cross-section of the receiving groove 4 is U-shaped and the opening faces downward. The rear end of the handrail body 1 is an inwardly concave curved part 7.

[0021] The lower surface of the handrail body 1 is provided with several reinforcing ribs 16, all of which are located in the receiving groove 4, and the two ends of the reinforcing ribs 16 are fixedly connected to the two sides of the receiving groove 4. The reinforcing ribs 16 can effectively improve the structural strength and ensure the stability of the structure.

[0022] The handrail body 1 is provided with a set of countersunk holes 3 for fixing. In this embodiment, the set of countersunk holes 3 includes three countersunk holes 3, two of which are distributed on opposite sides of the handrail body 1, and the other countersunk hole 3 is located in the middle of the inner bend 7. The axis connecting the three countersunk holes 3 forms a triangle.

[0023] It should be noted that the armrest body 1 is fixed to the frame by three countersunk holes 3 and corresponding fasteners. The fasteners are preferably bolts. Since the axis connecting the three countersunk holes 3 forms a triangle, it constitutes three stable connection points, which can effectively improve the stability of the connection structure.

[0024] Furthermore, each of the three countersunk holes 3 is detachably equipped with a decorative cover 17. The decorative cover 17 is adapted to the countersunk hole 3 and is used to cover the countersunk hole 3, thereby hiding the countersunk hole 3 and the corresponding fasteners. This not only effectively improves the overall visual aesthetics, but also prevents rainwater or dust from directly intruding into the countersunk hole 3 and the corresponding fasteners, thus fundamentally ensuring the corrosion resistance and stability of the connection structure during long-term use.

[0025] Regarding how to achieve the detachability of the decorative cover 17, in this embodiment, positioning holes 18 are provided on the countersunk platforms of the three countersunk holes 3. The decorative cover 17 has positioning protrusions 19 that are adapted to the positioning holes 18. The positioning holes 18 are used for the positioning protrusions 19 to be inserted, and the positioning holes 18 circumferentially limit the positioning protrusions 19. The positioning holes 18 are in the shape of "D". It should be noted that since the decorative cover 17 is adapted to the countersunk holes 3, and the positioning holes 18 circumferentially limit the positioning protrusions 19, the stability of the decorative cover 17 in the countersunk holes 3 can be effectively guaranteed.

[0026] When installing the decorative cover 17, simply place the decorative cover 17 into the countersunk hole 3 and insert the positioning protrusion 19 on the decorative cover 17 into the positioning hole 18. When removing the decorative cover 17, simply use external force to disengage the decorative cover 17 and the positioning protrusion 19 from the countersunk hole 3 and the positioning hole 18 respectively. The operation is simple and the disassembly and assembly are convenient.

[0027] The two sides of the armrest body 1 are armrest areas 2, which are the force-bearing areas for passengers to grip. Two armrest blocks 8 are detachably connected to the lower surface of the armrest body 1. In this embodiment, the armrest blocks 8 are connected to the armrest body 1 by bolts.

[0028] Two handrail blocks 8 are distributed on both sides of the handrail body 1. Both handrail blocks 8 are located in the receiving groove 4. The handrail blocks 8 correspond to the handrail area 2. That is, when the passenger grips the handrail area 2, the passenger also grips the handrail blocks 8. Furthermore, the lower surface of the handrail blocks 8 protrudes from the receiving groove 4, thus making it easier for the passenger to grip.

[0029] The two side walls of the armrest block 8 abut against the two side walls of the receiving groove 4, thereby realizing the supporting effect of the armrest block 8 on the two side walls of the receiving groove 4, significantly improving the rigidity of the local structure, and further ensuring the stability of the armrest block 8, thereby reducing the possibility of the armrest block 8 shaking during use, and thus improving the stability of the rider's grip.

[0030] Furthermore, the lower surface of the armrest block 8 is provided with several evenly distributed anti-slip protrusions 9, which not only increases the friction between the armrest block 8 and the hand, thereby improving the stability of the rider's grip, but also significantly enhances the grip feel.

[0031] The lower surface of the handrail body 1 is provided with a set of mounting holes 5 for installing an extension shelf 20. The extension shelf 20 can be used to install a tail box. Of course, the extension shelf 20 can also be used to place other items. In this embodiment, the set of mounting holes 5 includes two mounting holes 5, which are distributed opposite to each other on both sides of the handrail body 1.

[0032] Furthermore, a set of mounting holes 5 are located within the receiving groove 4, thereby concealing the mounting holes 5. This not only effectively improves the overall visual aesthetics but also prevents rainwater or dust from directly intruding into the mounting holes 5 and the corresponding fasteners, thus fundamentally ensuring the corrosion resistance and stability of the connection structure during long-term use.

[0033] The lower surface of the armrest body 1 has a protrusion 10 corresponding to the mounting hole 5. The protrusion 10 is located in the receiving groove 4. The mounting hole 5 is located at the center of the protrusion 10. The extended shelf 20 has a U-shaped guide groove 12 corresponding to the protrusion 10. The U-shaped guide groove 12 is used to limit and guide the protrusion 10. The end of the U-shaped guide groove 12 has a connecting hole 14 corresponding to the mounting hole 5. When the protrusion 10 moves along the U-shaped guide groove 12 to its end, the mounting hole 5 is aligned with the connecting hole 14.

[0034] The U-shaped guide groove 12 guides the protrusion 10, making it easier to align the mounting hole 5 with the connecting hole 14. This simplifies the installation of the extension shelf 20 and effectively improves the installation efficiency of the extension shelf 20.

[0035] The lower surface of the inner bend 7 is provided with a set of mounting holes 6 for mounting the backrest 21 or the extended shelf 20. In this embodiment, the set of mounting holes 6 includes four mounting holes 6, which are distributed in pairs on both sides of the inner bend 7.

[0036] Furthermore, a set of mounting holes 2 6 are located within the receiving groove 4, thereby concealing the mounting holes 2 6. This not only effectively improves the overall visual aesthetics but also prevents rainwater or dust from directly intruding on the mounting holes 2 6 and the corresponding fasteners, thus fundamentally ensuring the corrosion resistance and stability of the connection structure during long-term use.

[0037] The lower surface of the inner curved part 7 has a protrusion 11 corresponding to the mounting hole 6. The protrusion 11 is located in the receiving groove 4. The mounting hole 6 is located at the center of the protrusion 10. The extended shelf 20 and the backrest 21 are both provided with U-shaped guide grooves 13 corresponding to the protrusion 11. The U-shaped guide grooves 13 are used to limit and guide the protrusion 11. The end of the U-shaped guide grooves 13 is provided with a connecting hole 15 corresponding to the mounting hole 6. When the protrusion 11 moves along the U-shaped guide grooves 13 to its end, the mounting hole 6 is aligned with the connecting hole 15.

[0038] The U-shaped guide groove 213 guides the protrusion 21, making it easier to align the mounting hole 26 with the connecting hole 25. This simplifies the installation of the extension shelf 20 and backrest 21 and effectively improves the installation efficiency of the extension shelf 20 and backrest 21.

[0039] It should be noted that when installing the extension shelf 20, it is necessary to use corresponding fasteners to connect it to the armrest body 1 using two mounting holes 5, two connecting holes 14, four mounting holes 6, and four connecting holes 15. When installing the backrest 21, it is necessary to use corresponding fasteners to connect it to the armrest body 1 using four mounting holes 6 and four connecting holes 15. Bolts are preferred as the fasteners.

[0040] In this embodiment, the backrest 21 or the extended shelf 20 can be selectively installed, thereby diversifying the functions of the rear armrest and effectively meeting the diverse needs of users.
