[0036] In existing bicycles or other vehicles that rely on mechanical braking systems, the braking mechanism usually involves a physical connection between the brake cable and the handlebar. By operating the brake switch on the handlebar, the operating force is transmitted to the brake cable, thereby achieving control of the braking force on the wheel. The length of the brake cable is usually fixed to ensure stable braking performance. In retractable or foldable vehicles, in order to enable the brake cable to adapt to the expansion and contraction of the vehicle and keep the braking performance unaffected, designers usually leave an appropriate margin in the length of the brake cable. This results in a longer brake cable, which takes up more space, and in the state after the vehicle is expanded, contracted, or folded, it is difficult to store or carry the brake cable compactly, and there is a risk that the brake cable will become entangled or knotted on its own.

[0037] Therefore, a brake cable connection structure that can flexibly adapt to the expansion and contraction of the handlebar is needed. It can achieve dynamic adjustment of the length without sacrificing braking performance, while improving the safety and aesthetics of the vehicle.

[0038] In view of this, on the one hand, an embodiment of this application provides a braking structure 100, such as Figure 1As shown, the braking structure 100 includes a connecting component 110 and a braking component 120. The braking component 120 includes a first brake cable 121 and a second brake cable 122. The connecting component 110 connects the first brake cable 121 and the second brake cable 122. When the first brake cable 121 moves, it drives the second brake cable 122 to move through the connecting component 110.

[0039] The brake cable is divided into a first brake cable 121 and a second brake cable 122. The connecting component 110 connects the first brake cable 121 and the second brake cable 122 respectively, thereby reducing the total length of the brake cable and the occupied space of the brake cable. The first brake cable 121 is connected to the brake switch 123, and the second brake cable 122 is connected to the wheel 130. The connecting component 110 can also ensure that the second brake cable 122 moves synchronously through the connecting component 110 when the first brake cable 121 is operated (pressing the brake switch 123), realizing rapid transmission of the operating force and braking the wheel 130 to ensure that the braking performance is not affected by the shortening of the brake cable length. Moreover, the design of this braking structure 100 is applicable to retractable or foldable vehicles, and the brake cable will not change with the folding or retraction of the vehicle, avoiding self-winding or entanglement of the brake cable.

[0040] Considering that the braking structure 100 also needs to be applied to retractable or foldable vehicles, the brake cable is usually connected to the brake switch 123 on the handle for use when operating the brake. In this case, the brake cable may be pulled by two different operating forces: such as Figure 1 and Figure 2 As shown, taking the handle of the vehicle that can be adjusted up and down in height as an example, the first is that when the handle is telescoped up and down to adjust the height, it may pull the brake cable; the second is when the brake switch 123 on the handle is pressed to brake. However, if the brake cable is also pulled when adjusting the height of the handle, this may lead to unstable tension, thereby affecting the consistency and reliability of the braking performance. Moreover, it increases the risk of brake cable wear, may cause brake response delay or inaccuracy, and increases the safety risk.

[0041] In view of this, to ensure that the brake cable is only pulled to achieve braking when braking is needed, and remains stable when adjusting the height of the handle without being unnecessarily pulled. In the embodiments of the present application, as Figure 1 、 Figure 2 and Figure 3 As shown, the connecting component 110 includes a connecting piece 111 and a sliding rod 112. The connecting piece 111 is connected to the sliding rod 112. When the first brake cable 121 moves, the connecting piece 111 drives the second brake cable 122 to move through the sliding rod 112.

[0042] By providing a sliding rod 112 and a connecting member 111, and the brake wire is divided into at least two segments. The sliding rod 112 is connected to the second brake wire 122. The connecting member 111 is respectively connected to the sliding rod 112 and the first brake wire 121, and the connecting member 111 is sleeved on the sliding rod 112 and can move on the sliding rod 112. When adjusting the height of the handle, only the first brake wire 121 moves upward with the handle. During the movement, the connecting member 111 moves on the sliding rod 112 with the first brake wire 121, realizing the adjustment of the handle height.

[0043] When braking is required, when the first brake wire 121 moves upward with the pressing of the brake switch 123, it drives the connecting member 111 to move upward accordingly, and then pushes the sliding rod 112 to move upward as well, thereby pulling upward the second brake wire 122 connected to the sliding rod 112, so as to apply the braking operation force of the brake switch 123 to the brake pads on the wheel 130 through the second brake wire 122, realizing the stopping of the wheel 130. The precise control of the brake wire is realized, and braking is only performed when an operation force is applied to the brake switch 123 when braking is required. The brake structure 100 provided by the embodiment of the present application can not only provide effective braking force when needed, but also remain stable when the vehicle needs to be telescoped or folded for adjustment, avoiding the change of the tension of the brake wire and causing unnecessary wear to the brake wire or the brake assembly 120, improving the practicability and reliability of the brake assembly 120.

[0044] Furthermore, as Figure 1 、 Figure 3 and Figure 4 show, one end of the connecting member 111 is fixedly connected to the first brake wire 121, and the other end is connected to the sliding rod 112. There are many structural components that can connect the first brake wire 121 and the sliding rod 112 and can control or transmit mechanical force to enable the first brake wire 121 and the sliding rod 112 to move relative to each other or be moved, including but not limited to fork, coupling, gear, link, etc. In the embodiment of the present application, the connecting member 111 adopts a sheet shape as Figure 4 shown. The sliding rod 112 and the first brake wire 121 are respectively connected to opposite ends of the connecting member 111, making the height of the connecting member 111 smaller, providing a larger displacement while keeping the structure small and compact, enabling the brake structure 100 to flexibly adapt to handles of different heights and making the adjustable range of the handle height wider.

[0045] Even further, as Figure 3 and Figure 4 show, the connection assembly 110 further includes an elastic member 113 and a stopper for resetting the connecting member 111. The elastic member 113 is sleeved on the sliding rod 112.

[0046] By setting the elastic member 113 and the stopper 114, the stable reset and precise control of the connecting member 111 are achieved. The elastic member 113, such as a spring, is sleeved on the sliding rod 112 and functions to restore the connecting member 111 to its initial position when the brake switch 123 is released. This ensures that the brake cable can quickly return to its initial state after being released, and also improves the response speed and reliability of the entire brake structure.

[0047] The stopper 114 is responsible for restricting the telescopic range of the elastic member 113, thereby limiting the movable range of the connecting member 111 when it is pulled by the first brake cable 121. This prevents the connecting member 111 from exceeding the predetermined position during movement, avoids overstretching or damaging the brake cable, maintains the tension stability of the brake cable, and also enhances the durability and safety of the brake structure 100.

[0048] Specifically, please continue to refer to Figure 3 and Figure 4 and in combination with Figure 5 , the stopper is formed as a housing 115. The connecting member 111 is located inside the housing 115 and moves within the height range of the housing 115. The connecting member 111 is provided with a through hole 116 for accommodating the sliding rod 112, and the sliding rod 112 passes through the housing 115 and is connected to the second brake cable 122.

[0049] The brake assembly 120 further includes a brake switch 123. When the brake switch 123 is pressed, the first brake cable 121 moves in the first direction, driving the end of the connecting member 111 having a fixing hole 117 to move in the first direction, and the through hole 116 abuts against the sliding rod 112.

[0050] The stopper 114 is designed as a hollow square-shaped housing 115, as shown in Figure 3 and Figure 4 . The four side edges of the square-shaped housing 115 act as baffles to limit the connecting member 111 in multiple directions, and the upper and lower side edges of the housing 115 effectively limit the movement and reset range of the connecting member 111 in the vertical direction.

[0051] During braking, the first brake cable 121 drives one end of the connecting member 111 Figure 3 to move upward at the upper right end in the figure. At this time, the connecting member 111 is in an inclined state inside the housing 115. Since the other end of the connecting member 111 is sleeved on the sliding rod 112 and is not fixed, when the connecting member 111 continues to move upward, it may not only move vertically upward but also rotate or move horizontally. The left and right side edges of the square-shaped housing 115 play a guiding role for the connecting member 111 to ensure the movement stability of the connecting member 111 in the horizontal direction. Through the square-shaped setting of the housing 115, all-round movement restriction is provided for the connecting member 111, thereby preventing it from exceeding the predetermined movement range in any direction to precisely control the brake.

[0052] Similarly, when the brake switch 123 is released, the elastic member 113 pushes the connecting member 111 to reset. The stop member formed as a square box-shaped housing 115 structure ensures that the connecting member 111 does not deviate from the predetermined path during the reset process and can accurately return to the initial position when reset. This improves the stability and reliability of the brake structure 100 and reduces potential failures caused by the displacement of the connecting member 111.

[0053] In addition, the hollow design of the stop member 114 can also reduce weight and manufacturing costs. By reducing the use of materials, the housing 115 achieves lightweight without sacrificing strength and durability, making the brake structure 100 provided by the embodiments of the present application smaller and easier to maintain.

[0054] As Figure 5 shown, the connecting member 111 is provided with a through hole 116 for accommodating the sliding rod 112 and a fixing hole 117 fixedly connected to the first brake wire 121. Corresponding through holes 116 are also provided on the housing 115 corresponding to and communicating with the through hole 116 so that the sliding rod 112 can pass through the housing 115 and be connected to the second brake wire 122.

[0055] To implement the technical solution in the above embodiments that the connecting member 111 does not pull the second brake wire 122 when the handle is telescoped, causing unnecessary braking, the connecting member 111 and the housing 115 move on the sliding rod 112; only when braking, the connecting member 111 pushes the sliding rod 112 to pull the second brake wire 122. The connecting member 111 is sleeved on the sliding rod 112 through the through hole 116, and there is a certain gap between the through hole 116 and the outer wall of the sliding rod 112.

[0056] When the brake switch 123 is pressed to pull the first brake wire 121 upward, one end of the connecting member 111 connected to the first brake wire 121, that is, Figure 3 the right side of the connecting member 111 in the figure is first pulled. As this pulling occurs, the whole connecting member 111 tilts upward from left to right. At this time, the through hole 116 on the left side of the connecting member 111 abuts against the outer wall of the sliding rod 112 due to the tilt of the connecting member 111. As the connecting member 111 continues to move upward, the left side of the connecting member 111 also moves upward, thereby pushing the sliding rod 112 that abuts against it through the through hole 116 to move upward. The upward movement of the sliding rod 112 directly acts on the second brake wire 122, thereby realizing the pulling of the second brake wire 122 and the effective transmission of the braking force, thus completing the braking operation.

[0057] When the brake switch 123 on the handle is not pressed and only the height of the handle is adjusted, the sliding rod 122 penetrates the housing 115, and the housing 115 can move on the sliding rod 112. The connecting member 111 is arranged inside the housing 115. When the housing 115 moves on the sliding rod 112 as the handle expands and contracts, it will drive the connecting member 111 to move on the sliding rod 112 accordingly, avoiding pulling the second brake wire 122, and thus avoiding unnecessary braking when the handle expands and contracts.

[0058] Further, continue Figure 3 As shown, the stopper 114 of the present application is further provided with a washer 119 arranged in a ring shape, which is arranged around the lower side of the stopper 114. Since the stopper 114 moves as the telescopic rod of the handle expands and contracts, that is, the stopper 114 needs to be connected to the telescopic rod of the handle. The washer 119 is located between the stopper 114 and the inner wall of the telescopic rod. The washer 119 is made of wear-resistant and elastic materials such as rubber or silica gel, ensuring close fit between the stopper 114 and the inside of the telescopic rod of the handle while playing a buffering role, avoiding wear of the stopper 114, and improving the service life of the brake structure 100.

[0059] As can be seen from the above, the sliding rod 112 is not only an essential component for realizing the braking function but also one of the important components for ensuring the stability of the brake assembly 120 during expansion and contraction. The sliding rod 112 needs to be pushed during braking and remain stationary when the vehicle expands, folds, and contracts. To ensure that the sliding rod 112 can accurately reset after each braking and quickly return to the initial position to prepare for the next braking, in the embodiment of the present application, as Figures 1 to 5 shown, the connecting assembly 110 further includes a stopper 118. The stopper 118 is located between the sliding rod 112 and the second brake wire 122. The stopper 118 and the elastic member 113 are used to reset the sliding rod 112.

[0060] When the brake switch 123 is released, after the elastic member 113 loses the operating force, the connecting member 111 resets to the bottom end inside the housing 115, and the sliding rod 112 also returns downward to the initial position without the push of the connecting member 111. However, since the sliding rod 112 penetrates the connecting member 111 and the housing 115, and the housing 115 and the connecting member 111 need to slide on the sliding rod 112 to adjust the height of the handle, referring to Figure 4 and Figure 5 , the housing 115 is also provided with a through hole communicating with the through hole 116, so that there is a gap between the housing 115 and the connecting member 111 and the sliding rod 112. To prevent the sliding rod 112 from falling downward during reset and falling out of the through hole 116 of the connecting member 112 and the through hole of the housing 115 under the pull of the second brake wire 122 to separate from the housing 115, a stopper 118 is provided in the embodiment of the present application to ensure that the sliding rod 112 will not move excessively during the reset process, improving the stability of the brake structure 100.

[0061] As shown Figure 6 in FIG. 1, the brake assembly 120 further includes a brake caliper 124, which includes a pin-connected caliper fixed end 125 and a caliper movable end 126; the second brake cable 122 is connected to the caliper movable end 126, the caliper fixed end 125 is connected to the wheel 130, and the brake pads are located between the caliper fixed end 125 and the caliper movable end 126; when the brake switch 123 is pressed, the second brake cable 122 drives the caliper movable end 126 to approach the caliper fixed end 125, so that the brake pads are in contact with the wheel 130 to brake the wheel 130.

[0062] The pin-connected caliper fixed end 125 and caliper movable end 126 precisely control the contact between the brake pads and the wheel 130, thereby achieving effective braking. When the brake switch 123 is pressed, the second brake cable 122 is immediately pulled, and the brake cable transmits the braking operating force to the caliper movable end 126. As the caliper movable end 126 moves, the brake pads are pushed towards the caliper fixed end 125 and then closely contact the surface of the wheel 130. This contact generates frictional force and applies a braking force to the wheel 130, thereby achieving the purpose of deceleration or stopping.

[0063] In addition, the design of the brake caliper 124 allows adjustment of the pressure between the brake pads and the wheel 130 to adapt to different braking requirements and road conditions. This adjustment ability further improves the adaptability and safety of the brake structure 100.

[0064] According to another aspect of the embodiments of the present application, as Figure 7 shown in FIG. 2, a walking-assist vehicle 200 is provided, which includes any one of the above-mentioned brake structures 10*. The front wheel of the walking-assist vehicle 200 is usually responsible for steering, and the rear wheel is responsible for braking. The above-mentioned brake structure 100 can be arranged in the vehicle rod connected to the rear wheel. The number of wheels 130 of the walking-assist vehicle 200 may also be four, and the number of brake structures 100 can be correspondingly set according to the number of wheels 130, especially the number of wheels 130 that need to achieve braking.

[0065] According to another aspect of the embodiments of the present application, a transportation vehicle is provided, which includes any one of the above-mentioned brake structures. The transportation vehicle includes, but is not limited to, bicycles, electric vehicles, motorcycles, or simulation game vehicles, etc., which can travel and require mechanical braking.

[0066] *Note: There seems to be a typo in the original text where it says "10*" in ID=14. It should probably be "100" for consistency. This has been maintained in the translation.It should be noted that for the braking structure 100 provided by the embodiments of the present application, by dividing the brake cable into at least two segments, the length is reduced compared to the overall length of the existing brake cable, and the occupied space is reduced. The brake cable is always in a straight state and will not be wound or bent when the telescopic mechanism retracts. The occupied space of the brake cable is thus reduced. Therefore, the braking structure 100 can be compactly arranged inside the telescopic mechanism of the vehicle, such as the main pole of the vehicle, the folding pole of the vehicle, or the telescopic handle of the vehicle, etc., enabling the brake assembly 120 to be installed inside the telescopic mechanism of the vehicle, achieving a hidden layout and improving the neatness and aesthetics of the vehicle appearance. It avoids the brake cable or the brake assembly 120 from being exposed and possibly being caught by obstacles. At the same time, the braking structure 100 is sealed inside the vehicle and is not visible, playing a role in protecting the entire braking structure 100, enabling the braking structure 100 to withstand harsh weather conditions such as rain and mud, and enhancing the service life of the braking structure 100.

[0067] For the embodiments of the present application, it should also be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other to obtain new embodiments.

[0068] The above are only the preferred embodiments of the present application, and do not impose any form of limitation on the present application. The protection scope of the present application should be subject to the protection scope of the claims.
