Technical Field
[0001] The present application relates to the field of bicycle accessories, and in particular to a bicycle tail rack structure. Background Art
[0002] In today's society, bicycles are widely used in daily life as a convenient and environmentally friendly means of transportation. To meet people's needs for carrying items while riding, most bicycles are equipped with tail racks, also known as bicycle pillions. These tail racks are usually mounted on the rear axle of the bicycle to facilitate the secure and carrying of various items. Of course, some users also use tail racks to carry passengers. However, according to traffic regulations, in most cases, bicycles are not allowed to carry passengers. Therefore, the main function of tail racks is to carry items.
[0003] To further enhance the carrying capacity of tail racks, current tail racks often feature a U-shaped upper structure. This design offers the advantage of easier securing and positioning of items, significantly increasing the storage space. However, this design also has its drawback: it increases the height of the rear of the bicycle. Bicycles designed for professional riding often incorporate a connecting tube between the seat and front rack to maintain stability and balance. This allows the rider to place one leg over the rear of the rear rack, allowing both legs to be positioned on either side of the bicycle, resulting in a more comfortable and efficient ride.
[0004] However, if the height of the tail rack is increased, it will make it more difficult for the rider to get on and off the bicycle, thereby affecting the rider's riding experience. Utility Model Content

DETAILED DESCRIPTION
[0034] The following is combined with Figure 1-5 This application is described in further detail.
[0035] The embodiment of the present application discloses a bicycle tail rack structure. Figure 1 and Figure 2 The bicycle tail rack structure includes a loading frame 1 for placing items and a mounting portion 2 for fixing the loading frame 1 on the bicycle. The loading frame 1 includes a first placement rack 11 and a second placement rack 12. The second placement rack 12 is fixedly connected to one end of the first placement rack 11 and together with the first placement rack 11 forms a loading space 13. During use, when the loading frame 1 is installed on the bicycle via the mounting portion 2, the upper surface of the loading frame 1 can be horizontal. At this time, the height of the first placement rack 11 gradually decreases from the end away from the second placement rack 12 to the end close to the second placement rack 12, forming an inclined surface, which facilitates the placement of items and prevents items from sliding during riding.
[0036] The first rack 11 and the second rack 12 are arranged at an angle. This design can further increase the loading space 13 while maintaining the stability of the loading frame 1. The angle between the first rack 11 and the second rack 12 can be an acute angle, a right angle, or an obtuse angle. This application uses the obtuse angle between the first rack 11 and the second rack 12 as an example for description.
[0037] In addition, a limit frame 14 is fixedly connected between the end of the first placement rack 11 away from the second placement rack 12 and the end of the second placement rack 12 away from the first placement rack 11. The setting of the limit frame 14 can close the loading space 13, improve the placement stability of the items in the loading space 13, and reduce the probability of the items slipping out of the loading space 13.
[0038] Reference Figure 2 and Figure 3At the same time, a placement plate 15 is fixedly connected between the first placement rack 11, the second placement rack 12, and the limit frame 14. The placement plate 15 can block the bottom of the loading space 13, so that even if the items placed in the loading space 13 are small or have the potential to roll, they can be effectively confined within the loading space 13 and will not fall from the gap between the first placement rack 11 and the second placement rack 12. The fixing stability between the first placement rack 11 and the second placement rack 12 is improved, and the supporting force of the first placement rack 11 away from the second placement rack 12 and the supporting force of the second placement rack 12 away from one end of the first placement rack 11 is increased, so as to prevent the items placed in the loading space 13 from sliding out of the loading space 13 due to the free end of the first placement rack 11 or the free end of the second placement rack 12 shaking during the movement of the bicycle.
[0039] Reference Figure 2 and Figure 3 The first placement rack 11 includes two parallel first placement rods 111. The second placement rack 12 is generally U-shaped, with the two U-shaped openings of the second placement rack 12 fixedly connected to the ends of the two first placement rods. To ensure the secure placement of items within the loading space 13, a first reinforcement rod 112 is fixed between the two first placement rods 111. Multiple first reinforcement rods 112 are spaced along the length of the first placement rods 111 to support items within the loading space 13.
[0040] Reference Figure 2 and Figure 3 The mounting portion 2 includes two parallel mounting rods 22, each of which is fixed to the side of the first placement frame 11 facing away from the cargo space 13. The mounting rods 22 are respectively fixed to the two first placement rods 111. The design of the support frame allows the rear wheel of the bicycle to fit between the two mounting rods 22, thereby stably fixing the cargo frame 1 to the bicycle.
[0041] The mounting rods 22 are used to connect to the bicycle, thereby fixing the cargo frame 1 on the bicycle. In order to increase the connection strength of the mounting rods 22 , a second reinforcing rod 24 is fixed between the two mounting rods 22 .
[0042] The width of the placement plate 15 can be set to be greater than or equal to the width between the two mounting rods 22 to increase the area of the cargo space 13 and improve the storage capacity.
[0043] Reference Figure 3 and Figure 4In one example of the present application, the mounting rod 22 includes a first rod 221 fixed to the first placement rod 111, a second rod 222 fixed to the first placement rod 111, and a connecting rod 223 fixed between the first rod 221 and the second rod 222. The first rod 221 and the second rod 222 are respectively located at opposite ends of the first placement rack 11, while the connecting rod 223 is located at the ends of the first rod 221 and the second rod 222 away from the first placement rod 111. The connecting rod 223 is used to connect to the bicycle frame, ensuring stable fixation of the cargo frame 1 on the bicycle.
[0044] Reference Figure 5 In another example of the present application, the mounting rod 22 includes a third rod 224 fixedly connected to the first placement rod 111 and a fourth rod 225 fixedly connected to the first placement rod 111. The third rod 224 and the fourth rod 225 are respectively located at opposite ends of the first placement rack 11. The end of the third rod 224 away from the first placement rod 111 and the end of the fourth rod 225 away from the first placement rod 111 are close to each other, forming a stable triangular support structure between the third rod 224, the fourth rod 225, and the first placement rod 111. A connecting ring 226 is fixedly connected to the end of the third rod 224 away from the first placement rod 111 and the end of the fourth rod 225 away from the first placement rod 111. During use, the connecting ring 226 is simply placed on the rear wheel mounting axle of the bicycle to secure the position of the cargo carrier 1 on the bicycle.
[0045] The implementation principle of the bicycle tail rack structure of the embodiment of the present application is as follows: when in use, the mounting rod 22 is directly fixed to the bicycle to complete the installation and fixation of the cargo frame 1. After installation, the upper surface of the cargo frame 1 is in a horizontal state, that is, the limiting frame 14 is in a horizontal state, so as to form a triangular cargo space 13. While meeting the rider's need for storage space, it does not affect the rear height of the bicycle, thereby ensuring the rider's riding experience.
[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
