Description

Technical Field

[0001] The embodiments of this utility model relate to the field of bicycle technology, and more specifically, to a bicycle frame structure and a bicycle. Background Technology

[0002] Bicycles, as a green, environmentally friendly, convenient, and flexible means of transportation, are widely used worldwide. With the diversification of people's lifestyles and the increasing demand for convenience and functionality in travel, bicycles are no longer limited to simple transportation; they have gradually become important equipment for activities such as sports, fitness, and leisure travel. During a ride, cyclists often need to carry various items, such as mobile phones, water bottles, or food.

[0003] In today's bicycle market, common ways to store relatively small items include front-mounted bags, top tube bags, triangle bags, and rear bags.

[0004] Front-mounted bags are cleverly secured to the front of the bicycle handlebars using specific hooks or straps, allowing riders to easily view and retrieve items, especially suitable for storing frequently used small items such as mobile phones and keys. Top-tube bags are installed in the top tube area of ​​the bicycle, close to the frame, saving space to some extent while also allowing riders easy access to the contents. Triangle bags are generally placed in the triangular area of ​​the bicycle frame, making full use of this unused space and accommodating many small items. Rear-mounted bags are installed on the rear seat or rear rack of the bicycle, offering a relatively large capacity for storing slightly larger small items such as small tools and raincoats.

[0005] However, regardless of which method of storage is used, a thorny problem inevitably arises—the bag is highly susceptible to being crushed under certain circumstances. During cycling, various complex situations may arise, such as minor collisions with other vehicles or objects, being squeezed by passersby or objects while riding on congested roads, or being accidentally run over by heavy objects when parking. Once the bag is crushed, the items inside are often not spared either. At best, the items will be deformed, affecting normal use; at worst, they will be completely damaged and rendered unusable. This undoubtedly causes significant inconvenience and loss for the cyclist. Utility Model Content

[0006] In order to solve one or more of the technical problems mentioned above, according to a first aspect of the present invention, the present invention provides a bicycle frame structure and a bicycle, which on the one hand facilitates the rider to take in his / her belongings, and on the other hand avoids the problem that the bag is easily crushed.

[0007] The bicycle frame structure includes:

[0008] The downtube is located between the head tube and the chainstay of the bicycle.

[0009] The top tube is located between the seat tube and the head tube of the bicycle and above the down tube;

[0010] A connecting pipe, which is parallel to the upper pipe and disposed between the seat pipe and the lower pipe;

[0011] The seat post, the upper tube, and the lower tube are connected to each other and together form a housing space. The vehicle body structure also includes a bag installed in the housing space for holding the rider's belongings.

[0012] Furthermore, the accommodating space is configured as an inverted trapezoid, and the hanging bag is configured as an inverted trapezoid adapted to the accommodating space.

[0013] Furthermore, the bag is a flat bag.

[0014] Furthermore, the bag is distributed in a mirror-symmetrical manner with the longitudinal central axis of the upper tube as the axis of symmetry, and the thickness of the bag along the direction perpendicular to the bicycle's travel direction is 1cm-2cm larger than the diameter of the upper tube.

[0015] Furthermore, the connection point between the upper tube and the lower tube is located at the center of the lower tube.

[0016] Furthermore, the vehicle body structure also includes a plurality of screws disposed within the hanging bag, the hanging bag being connected to the upper tube by some of the screws and to the connecting tube by the other portion of the screws.

[0017] Furthermore, the hanging bag includes a bag body, a pocket body disposed within the bag body, and a zipper structure disposed on the bag body.

[0018] Furthermore, the package body is made of a waterproof material.

[0033] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0034] Figure 1 This embodiment shows a schematic diagram of the bicycle frame structure. Figure 2 A schematic diagram of the vehicle body structure provided in this embodiment, excluding the hanging bag 5, is shown. For example... Figure 1 and Figure 2 As shown, this embodiment provides a bicycle frame structure, including a downtube 1, a top tube 2, a connecting tube 3, and a bag 5. The downtube 1 is located between the head tube 100 and the chainstay 200 of the bicycle. The top tube 2 is located between the seat tube 300 and the head tube 100 and is situated above the downtube 1. The connecting tube 3 is parallel to the top tube 2 and is located between the seat tube 300 and the downtube 1. A portion of the seat tube 300, the top tube 2, a portion of the downtube 1, and the connecting tube 3 are interconnected and together form a storage space 4. The bag 5 is installed within the storage space 4 and is used to hold the rider's belongings.

[0035] The vehicle structure provided in this embodiment has several advantages. Firstly, the placement of the storage space 4, located between part of the seat post 300, the top tube 2, part of the bottom tube 1, and the connecting tube 3, allows the rider to easily access items in the bag 5 by bending slightly forward. This significantly optimizes the placement of items and greatly facilitates the rider's access to their belongings during riding, enhancing convenience and comfort. Secondly, the interconnected structure of part of the seat post 300, the top tube 2, the bottom tube 1, and the connecting tube 3 forms the storage space 4 for the bag 5. When the bag 5 is placed within this space, the structure protects it from external pressure. This design and efficient space planning cleverly avoid the common problem of traditional bags being easily crushed during riding, providing reliable protection for the items inside and ensuring they remain intact.

[0036] Furthermore, the storage space 4 is configured as an inverted trapezoid, and the bag 5 is configured as an inverted trapezoid that matches the storage space 4. The inverted trapezoid utilizes the characteristics of its own structure to ensure the stability and support strength of the overall bicycle structure. On the basis of the former, it can also effectively utilize the limited space within the bicycle structure to place a larger capacity bag 5, thereby improving the carrying capacity of the bicycle structure.

[0037] Furthermore, the bag 5 is a flat bag to reduce the possibility of the rider coming into contact with the bag 5 when getting on and off the bicycle, thereby reducing the possibility of interference from external factors.

[0038] Specifically, the longitudinal central axis of the upper tube 2 of the bag 5 is the axis of symmetry and is distributed in a mirror symmetry. The thickness of the bag 5 along the direction perpendicular to the bicycle travel direction is 1cm-2cm larger than the diameter of the upper tube 2, so as to reduce the possibility of the rider coming into contact with the bag 5 when getting on and off the bicycle.

[0039] In this embodiment, the vehicle structure also includes multiple screws disposed within the hanging bag 5. The hanging bag 5 is connected to the upper tube 2 via some screws and to the connecting tube 3 via others. In other embodiments, the hanging bag 5 can also be connected to the upper tube 2 and the connecting tube 3 via a snap-fit ​​structure or a magnetic structure. Compared to snap-fit ​​or magnetic structures, screws provide better stability after fixing, thus reducing the possibility of the hanging bag 5 falling off due to bumps during bicycle riding. This embodiment does not specifically limit this; any installation structure that can install the hanging bag 5 in the accommodating space 4 should be within the protection scope of this disclosure.

[0040] Furthermore, the bag 5 includes a bag body, a pocket disposed within the bag body, and a zipper structure disposed on the bag body, to facilitate the retrieval, placement, and storage of the cyclist's belongings. Since the specific structure of the bag 5 is prior art known to those skilled in the art, it will not be described in detail here to save space.

[0041] Furthermore, the package is made of waterproof material.

[0042] Specifically, waterproof materials include PVC mesh fabric or TPU laminated fabric, etc. Since the waterproof materials of the package are already known to those skilled in the art, they will not be described in detail here to save space.

[0043] Furthermore, the hanging bag 5 also includes a pressure-resistant support component disposed inside the bag and used to support the bag body, so as to provide support for the bag body of the hanging bag 5, thereby ensuring the holding capacity of the hanging bag 5 and reducing the possibility of the bag body being squeezed and causing compression to the items carried inside the bag.

[0044] Specifically, the compression support components include load-bearing brackets and connecting brackets, etc. Since the compression support components inside the hanging bag 5 are existing technologies known to those skilled in the art, they will not be described in detail here to save space.

[0045] This embodiment also provides a bicycle, including the frame structure, head tube 100, seat tube 300 and chainstay 200 as described above.

[0046] The bicycle provided in this embodiment improves the rider's riding experience due to the adoption of the above-described frame structure.
