[0015] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0016] In the description of this application, it should be noted that the terms "inner", "outer", "left", "right", "upper", "lower", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0017] In the description of this application, unless otherwise expressly specified and limited, the terms “set up,” “install,” “connect,” and “link” shall be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection; as a mechanical connection or an electrical connection; as a direct connection or an indirect connection through an intermediate medium; or as a connection within two components.

[0018] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings.

[0019] Example Reference Figures 1-6 This utility model provides a foot brake cable, including a foot brake cable body 100, a first connecting part 600 is provided at one end of the foot brake cable body 100, a limiting member 700 is provided on the first connecting part 600, and a thread is provided on the first connecting part 600, the thread forming a threaded part 603, the threaded part 603 being located at the other end of the first connecting part 600 away from the foot brake cable body 100; A fastening nut 110 is screwed onto the threaded portion 603. The fastening nut 110 cooperates with the limiting member 700 to clamp the limiting plate 200.

[0020] In some embodiments, one end of the foot brake cable body 100 has a first connecting portion 600, and a limiting member 700 is provided on the first connecting portion 600. When the first connecting portion 600 is inserted into the limiting hole of the limiting plate 200, the limiting member 700 abuts against the limiting plate 200 to prevent the first connecting portion 600 from completely passing through the limiting hole. The threaded portion 603 on the first connecting portion 600 can completely pass through the limiting hole. The fastening nut 110 is screwed onto the threaded portion 603 of the first connecting portion 600 and abuts against the limiting plate 200. In this way, the fastening nut 110 and the limiting member 700 cooperate to clamp the limiting plate 200, so that the first connecting portion 600 cannot be disengaged from the limiting plate 200, ensuring effective braking and guaranteeing user safety.

[0021] Reference Figure 6 In an optional embodiment, a limiting nut 120 is provided on the threaded portion 603, and the limiting nut 120 forms the limiting member 700.

[0022] In some embodiments, the limiting member 700 is a limiting nut 120, that is, the limiting nut 120 is screwed onto the threaded portion 603. Both the limiting nut 120 and the fastening nut 110 can move on the threaded portion 603 and clamp the limiting plate 200. They can also prevent the first connecting portion 600 from separating from the limiting plate 200, and can adjust the relative position of the first connecting portion 600 and the limiting plate 200 within a certain range.

[0023] Reference Figure 3 In an optional embodiment, the first connecting portion 600 includes a front connecting portion 602 and a rear connecting portion 601, and the limiting member 700 is disposed between the front connecting portion 602 and the rear connecting portion 601. A front through hole is provided on the front connecting part 602, and a rear through hole is provided on the rear connecting part 601, and the front through hole and the rear through hole are connected. The foot brake cable body 100 includes a foot brake cable outer shell 800 and a foot brake cable core 900. The foot brake cable outer shell 800 is sleeved on the foot brake cable core 900, and the foot brake cable core 900 enters from the rear through hole to the front through hole and extends out from the front through hole. The foot brake cable housing 800 is inserted into the rear through hole and connected to the rear connecting part 601.

[0024] In some embodiments, the first connecting portion 600 includes a front connecting portion 602 and a rear connecting portion 601. A limiting member 700 is provided between the front connecting portion 602 and the rear connecting portion 601. The limiting member 700 has a circular outer hub. When the limiting member 700 abuts against the limiting plate 200, the limiting member 700 abuts against the limiting hole of the limiting plate 200 in a uniform circumferential direction, so that the circumferential side of the limiting hole is subjected to uniform force.

[0025] The foot brake cable body 100 has its outer shell 800 inserted into the rear through hole and fixedly connected to the rear connecting part 601. The foot brake cable core 900 is inserted into the rear through hole, then passes through the front through hole, and finally exits from the front through hole.

[0026] In an optional embodiment, the outer diameter of the front connecting portion 602 is smaller than the outer diameter of the rear connecting portion 601, and the outer diameter of the rear connecting portion 601 is smaller than the outer diameter of the limiting member 700.

[0027] The outer diameter of the front connecting part 602 is relatively small, allowing it to be inserted into the limiting hole of the limiting plate 200. The outer diameter of the rear connecting part 601 is larger than that of the front connecting part 602, and generally the outer diameter of the rear connecting part 601 is larger than the inner diameter of the limiting hole. The outer diameter of the limiting member 700 is the largest, and the limiting member 700 cannot be inserted into the limiting hole and abut against the limiting plate 200. The outer diameter of the rear connecting part 601 is larger than the inner diameter of the limiting hole, and the rear connecting part 601 can provide support for the limiting member 700, effectively increasing the strength of the limiting member 700.

[0028] In an optional embodiment, one end of the foot brake cable core 900 is provided with a front traction member 500. In an optional embodiment, a second connecting portion is provided at the other end of the foot brake cable body 100.

[0030] The foot brake cable body 100 provided by this utility model has a threaded portion 603 on its first connecting portion 600, and a fastening nut 110 on the threaded portion 603. After the foot brake cable body 100 is inserted into the limiting hole of the limiting plate 200, the fastening nut 110 is screwed onto the threaded portion 603. In this way, the fastening nut 110 and the limiting member 700 are located on both sides of the limiting plate 200 and clamp the limiting plate 200, ensuring that the foot brake cable body 100 does not separate from the limiting plate 200, ensuring effective braking, and ensuring user safety.

[0031] This utility model provides a foot brake assembly, including the foot brake cable described in any of the foregoing embodiments. In an optional embodiment, a foot brake 300 and a limiting plate 200 are also included. The foot brake 300 is connected to the front traction member 500 of the foot brake cable. The first connecting part 600 of the foot brake cable is fixed on the limiting plate 200, and the limiting plate 200 is connected to the foot brake 300 through a tension spring 400.
