Description

Technical Field

[0001] The embodiments of the utility model relate to the technical field of a cargo bicycle foot support connection piece, and more specifically, the utility model relates to a foot support connection piece for a cargo bicycle and the cargo bicycle. Background Art

[0002] As a new type of transportation vehicle, cargo bikes are more flexible and convenient than medium and large transportation vehicles such as trucks, and can travel through the streets and alleys. However, as the carrying capacity of cargo bikes increases, their structural design and material selection also face greater challenges. Although the cargo bikes currently on the market have taken the needs of carrying cargo into consideration in their design, they still have deficiencies in the stability and durability of the connection between the footrest and the frame of the cargo bike.

[0003] In a cargo bicycle, the kickstand is an important component for supporting the body and carrying cargo. The stability of its connection with the frame is directly related to the safety performance of the entire bicycle. However, in actual use, since cargo bicycles need to carry heavy cargo, the connection between the kickstand and the frame is often subjected to large stress and torque, which can easily cause the connection parts to loosen, deform, or even break. This will not only affect the normal use of the cargo bicycle, but may also cause personal injury to the user. Utility Model Content

[0014] Further, the thickness of the first sub-reinforcement rib is greater than the thickness of the second sub-reinforcement rib; and

[0015] The thickness of the first sub-reinforcement rib is greater than the thickness of the third sub-reinforcement rib.

[0016] Furthermore, the first sub-reinforcement rib is welded to a pre-installation position of the vehicle frame.

[0034] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0035] Figure 1 The schematic diagram of the structure of the frame 100, the foot support 200 and the foot support connecting member provided in this embodiment is shown. Figure 2 Shows Figure 1 A partial enlarged view of the middle A. Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a cargo bicycle, which includes a frame 100, a foot support 200 and a foot support connecting member, and the foot support 200 is fixed to a pre-installed position of the frame 100 through the foot support connecting member.

[0036] With the cargo bicycle provided above, the structural strength and stability of the foot support connection piece are increased to prevent the risk of deformation and cracking of the foot support connection piece, thereby making the connection between the foot support 200 and the frame 100 more stable.

[0037] Figure 3 FIG. 2 shows a schematic diagram of the structure of the foot support connection member provided in this embodiment. Figure 3 Combined with Figure 1 and Figure 2 As shown, an embodiment of the utility model further provides a foot support connector for a cargo bicycle, the cargo bicycle comprising a frame 100 and a foot support 200, the frame 100 being provided with a pre-installation position, the foot support 200 being used to support the frame 100, the foot support connector comprising a connector body 1 and a reinforcing rib 2, the connector body 1 being connected to the foot support 200, the reinforcing rib 2 being provided along the edge of the connector body 1, and being connected to the pre-installation on the frame 100.

[0038] The first sub-reinforcement rib 21, the second sub-reinforcement rib 22 and the third sub-reinforcement rib 23 are provided to form the reinforcing rib strip 2. The first sub-reinforcement rib 21 is connected to the pre-installation position to increase the connection area between the connector body 1 and the frame 100, so as to effectively disperse the pressure of the cargo bicycle on the foot support 200 in the supporting state, avoid stress concentration, and cause the risk of deformation and cracking of the foot support connector, thereby improving the structural strength and stability of the connection between the connector body 1 and the foot support 200, and significantly improving the bearing capacity and anti-deformation ability of the foot support connector. Since the structural span of the first sub-reinforcement rib 21 is too large, the second sub-reinforcement rib 22 and the third sub-reinforcement rib 23 are provided to provide necessary support for the first sub-reinforcement rib 21, so that when the foot support 200 is in the supporting state, the first sub-reinforcement rib 21 can withstand the pressure caused by the cargo bicycle, thereby further improving the stability of the first sub-reinforcement rib 21, and further improving the bearing capacity and anti-deformation ability of the reinforcing rib strip 2.

[0039] Furthermore, the thickness of the first sub-reinforcement rib 21 is greater than the thickness of the second sub-reinforcement rib 22, and the thickness of the first sub-reinforcement rib 21 is greater than the thickness of the third sub-reinforcement rib 23. In order to ensure the structural strength and stability of the first sub-reinforcement rib 21, the first sub-reinforcement rib 21 can effectively disperse the pressure of the cargo bicycle on the kickstand 200 in the supporting state.

[0040] It should be noted that, in this embodiment, the thickness of the first sub-reinforcement rib 21 refers to the relative distance between the two sides of the first sub-reinforcement rib 21 in the vertical direction, and the thickness of the second sub-reinforcement rib 22 and the third sub-reinforcement rib 23 refers to the relative distance between their two sides in the longitudinal direction, and the vertical direction and the longitudinal direction are perpendicular to each other.

[0041] Figure 4 FIG. 2 shows a side view of the foot support connector provided in this embodiment. Figure 4 Combined with Figure 1-Figure 3As shown, in this embodiment, the second sub-reinforcement rib 22 includes a first inclined surface 221 disposed opposite to the surface of the connector body 1, the first inclined surface 221 is connected to the first sub-reinforcement rib 21 on one side close to the first sub-reinforcement rib 21, and the relative height between the first inclined surface 221 and the surface of the connector body 1 gradually decreases in the direction away from the first sub-reinforcement rib 21. The third sub-reinforcement rib 23 includes a second inclined surface 231 disposed opposite to the surface of the connector body 1, the second inclined surface 231 is connected to the first sub-reinforcement rib 21 on one side close to the first sub-reinforcement rib 21, and the relative height between the second inclined surface 231 and the surface of the connector body 1 gradually decreases in the direction away from the first sub-reinforcement rib 21. Thus, the second sub-reinforcement rib 22 and the third sub-reinforcement rib 23 can form two triangular structures, taking advantage of the stability of the triangular structure. When the first sub-reinforcement rib 21 is subjected to the pressure of the cargo bicycle, the two triangular structures of the second sub-reinforcement rib 22 and the third sub-reinforcement rib 23, each of the three edges of the triangular structure can withstand the pressure, thereby further enhancing the structural strength and stability of the reinforcing rib 2, reducing the risk of deformation or damage caused by single-point force. Compared with the rectangular structure, the triangular structure can reduce the material used in the manufacturing process of the foot support connector to reduce production costs. In other embodiments, the second sub-reinforcement rib 22 and the third sub-reinforcement rib 23 can also be set in other ways. Any structure that can enhance the structural strength and stability of the reinforcing rib 2 is within the protection scope of the disclosed embodiment.

[0042] As a preferred example, the first sub-reinforcement rib 21 is welded to the pre-installed position of the frame 100, so as to realize the fixed connection between the foot support connector and the frame 100.
