Description

Technical Field

[0001] This application relates to the field of braking devices, and more particularly to a safety braking device. Background Technology

[0002] In the design of motorcycles and electric bicycles, for ease of operation, the handbrake and throttle controls are usually concentrated on the right-hand handlebars. This layout allows the rider to control both braking and acceleration with one hand simultaneously, enabling quick response in emergencies and convenient switching between operations during daily riding. However, this presents a safety hazard in practical application. When the rider is wearing gloves and uses their right hand for emergency braking, the glove can easily cause the throttle to rotate accidentally due to the pressure of the hand, resulting in an unintended increase in throttle and causing acceleration while braking.

[0003] This situation not only reduces braking efficiency but also causes drivers to lose control of the vehicle's speed, increasing the risk of traffic accidents such as loss of control and skidding. This safety hazard caused by a design flaw is particularly dangerous, especially at high speeds or in complex and changing road environments. Summary of the Invention

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figures 1 to 5 This application first provides a safety braking device, which includes: Housing 01, transmission bearing assembly 02, throttle sliding assembly 03, brake sliding assembly 04, first connecting part 05, second connecting part 06, third connecting part 07, and brake connecting rod 08; The transmission bearing assembly 02 is installed inside the housing 01; The throttle sliding assembly 03 is disposed on one side of the transmission bearing assembly 02 and is connected to the transmission bearing assembly 02; One side of the throttle sliding assembly 03 is connected to the first connecting part 05, and the other side is connected to the second connecting part 06; The brake sliding assembly 04 is disposed on the other side of the transmission bearing assembly 02 and is connected to the transmission bearing assembly 02. One side of the brake sliding assembly 05 is connected to the third connecting part 07, and the other side is connected to the brake connecting rod 08; The transmission bearing assembly 02 is used to drive the throttle sliding assembly 03 and the brake sliding assembly 04 to move in opposite directions inside the housing 01 when driven by an external force. The first connecting part 05 is used to connect the engine throttle cable, the second connecting part 06 is used to connect the lever throttle cable, the third connecting part 07 is used to connect the brake disc brake cable, and the brake connecting rod 08 is used to connect the handbrake cable.

[0023] The transmission bearing assembly 02 is mounted at the center of the housing 01 and connected to the throttle sliding assembly 03 and the brake sliding assembly 04. One side of the throttle sliding assembly 03 is connected to the first connecting part 05, and the other side is connected to the second connecting part 06. The first connecting part 05 is connected to the engine throttle cable, and the second connecting part is connected to the lever throttle cable. One side of the brake sliding assembly 04 is connected to the third connecting part 07, and the other end is connected to the brake connecting rod 08. The third connecting part 07 is connected to the brake disc brake cable, and the brake connecting rod 08 is connected to the handbrake cable.

[0024] When the driver accelerates, the throttle cable is pulled, which moves the second connecting part 06 and the throttle sliding assembly 03. The throttle sliding assembly 03 moves the first connecting part 04 and simultaneously rotates the transmission bearing assembly 02. The transmission bearing assembly 02 then moves the brake sliding component 04 in the opposite direction.

[0025] When the first sliding component 04 moves, it drives the engine throttle cable, and the engine begins to accelerate. When the brake sliding component 04 moves in the opposite direction, it drives the third connecting part 07 and the brake connecting rod 08 to move. When the driver decelerates, the handbrake cable is pulled, which drives the brake connecting rod 08 and the brake sliding assembly 04 to move. The brake sliding assembly 04 drives the third connecting part 07 to move, and at the same time drives the transmission bearing assembly 02 to rotate. The transmission bearing assembly 02 drives the throttle sliding assembly to move in the opposite direction.

[0026] When the third connecting part 07 moves, it drives the brake disc and brake cable to achieve braking operation. When the throttle sliding assembly 03 moves in the opposite direction, the first connecting part 04 is driven by the throttle assembly 03 to pull back the throttle cable, and the second connecting part 05 is driven by the throttle sliding assembly 03 to return the engine throttle cable to its original position, and the engine stops accelerating.

[0027] Beneficial effects: The safety braking device provided in this application has a certain degree of versatility and can be adapted to different types of electric bicycles and motorcycles. The throttle sliding assembly 03 and the brake sliding assembly 04 move in opposite directions through the transmission bearing assembly 02. When the brake is pressed, the throttle cable will be released, the engine will stop accelerating, and the simultaneous acceleration and braking will be avoided, thus ensuring the stability of the brake.

[0028] In an optional embodiment, the outer surface of the housing 01 is provided with an engine cable hole 011, a throttle lever cable hole 012, a brake disc cable hole 013, and a handbrake cable hole 014. The housing 01 is provided with a first slide rail 015 and a second slide rail 016 inside. The throttle sliding assembly 03 is disposed on the first slide rail 015 and the brake sliding assembly 04 is disposed on the second slide rail 016. The engine throttle cable passes through the engine cable hole 011 and is connected to the first connecting part 05; the lever throttle cable passes through the lever throttle cable hole 012 and is connected to the second connecting part 06; the brake disc brake cable passes through the brake disc cable hole 013 and is connected to the third connecting part 07; and the handbrake cable passes through the handbrake cable hole 014 and is connected to the brake connecting rod 08. When driven by the transmission bearing assembly 02, the throttle sliding assembly 03 and the brake sliding assembly 04 can move in opposite directions via the first slide rail 015 and the second slide rail 016.

[0029] The exterior of housing 01 features an engine throttle cable hole 011, a throttle lever cable hole 012, a brake disc cable hole 103, and a handbrake cable hole 014, which are respectively used for passing the engine throttle cable, throttle lever cable, brake disc cable, and handbrake cable, and are connected to the first connecting part 05, the second connecting part 06, the third connecting part 07, and the brake connecting rod 08 inside the housing. The interior of housing 01 features a first slide rail 015 and a second slide rail 016, which respectively support and guide the movement of the throttle sliding assembly 03 and the brake sliding assembly 04. The throttle sliding assembly 03 is mounted on the first slide rail 015 and connected to the engine throttle cable via the first connecting part 05 and the throttle lever cable via the second connecting part 06. When the transmission bearing assembly 02 is driven to rotate by an external force, it causes the throttle sliding assembly 03 to slide on the first slide rail 015. The movement of the throttle sliding assembly 03 correspondingly pulls or releases the engine throttle cable and the throttle lever cable, thereby adjusting the engine throttle opening and controlling the vehicle's acceleration. The brake sliding assembly 04 is mounted on the second slide rail 016 and connected to the brake disc cable via the third connecting part 07, and to the handbrake cable via the brake connecting rod 08. When the brake is applied, the transmission bearing assembly drives the brake sliding assembly 04 to slide on the second slide rail 016. The movement of the brake 04 sliding assembly correspondingly pulls the brake disc cable and the handbrake cable, thereby activating the braking system and slowing the vehicle down.

[0030] Beneficial effects: By providing engine cable hole 011, throttle lever cable hole 012, brake disc cable hole 013, and handbrake cable hole 014 on the outside of housing 01, and then connecting the engine throttle cable, throttle lever cable, brake disc cable, and handbrake cable to the first connecting part 05, the second connecting part 06, the third connecting part 07, and the brake connecting rod, tangling of the cables can be effectively prevented. The housing 01 is internally provided with a first slide rail 015 and a second slide rail 016, providing a path for the throttle sliding assembly 03 and the brake sliding assembly 04 to move within the housing. The throttle sliding assembly 03 and the brake sliding assembly 04 move stably via the first slide rail 015 and the second slide rail 016, and are directly connected to the vehicle's engine and braking system via cables, allowing the driver to more accurately control the vehicle's acceleration and braking. This helps reduce the possibility of misoperation and enhances vehicle driving safety.

[0031] In an optional embodiment, the transmission bearing assembly 02 includes: a fixed shaft 021, a fixed shaft bearing 022, a transmission gear 023, and a bearing cover 024; The fixed shaft 021 is installed inside the housing 01, and the fixed shaft bearing 022 is installed on the fixed shaft 021; The transmission gear 023 is mounted on the fixed shaft 021 via the fixed shaft bearing 022; The bearing cover 024 is disposed on the fixed shaft bearing 022; When the transmission gear 023 is driven by an external force, it drives the throttle sliding assembly 03 and the brake sliding assembly 04 to move in opposite directions.

[0032] A fixed shaft 021 is installed inside the housing 01, serving as the reference and support for the transmission bearing assembly 02. A fixed shaft bearing 022 is mounted on the fixed shaft 021, connecting the transmission gear 023 and allowing the transmission gear 023 to rotate on the fixed shaft 021. The transmission gear 023 is mounted on the fixed shaft 021 via the fixed shaft bearing 022, allowing it to rotate on the fixed shaft 021. A bearing cover 024 is installed on the fixed shaft bearing 022 to protect it and prevent the ingress of dust, impurities, and other external substances. During acceleration, the throttle cable pulls the second connecting part 06, causing the throttle sliding assembly 03 to move. The transmission gear 023 is then rotated by the throttle sliding assembly 03, and this rotation causes the brake sliding assembly 04 to move in the opposite direction. During braking, the handbrake cable drives the brake connecting rod 08, which in turn moves the brake sliding assembly 04. The transmission gear 023 is driven to rotate by the brake sliding assembly 04, and this rotation causes the throttle sliding assembly 03 to move in the opposite direction. Specifically, when either the throttle sliding assembly 03 or the brake sliding assembly 04 drives the transmission gear 023 to rotate, it simultaneously drives the other component of either assembly, pushing them to move in opposite directions. Throughout this process, the fixed shaft bearing 022 supports the rotation of the transmission gear 023 and allows it to rotate on the fixed shaft 021. The bearing cover 024 protects the fixed shaft bearing 022 from external damage.

[0033] Beneficial effects: Power transmission is achieved through the fixed shaft 021, fixed shaft bearing 022, and transmission gear 023, improving transmission efficiency. This allows the throttle sliding assembly 03 and brake sliding assembly 04 to respond to external forces, enhancing vehicle handling sensitivity and response speed. The stable installation of the fixed shaft 021 and fixed shaft bearing 022, along with the transmission gear 023's mounting on the fixed shaft 021 via the fixed shaft bearing 022, allows the transmission gear 023 to rotate on the fixed shaft 021. The bearing cover 024 protects the fixed shaft bearing 022.

[0034] In an optional embodiment, the throttle sliding assembly 03 includes: a throttle toothed band 031 and a throttle slider 032; The throttle toothed belt 031 is installed above the throttle slider 032 and meshes with the transmission gear 023. One side of the throttle toothed belt 031 is connected to the first connecting part 05, and the other side is connected to the second connecting part 06.

[0035] The throttle sliding assembly 03 consists of a toothed throttle belt 031 and a throttle slider 032. One end of the toothed throttle belt 031 is connected to the first connecting part 05, and the other end is connected to the second connecting part 06. The toothed throttle belt 031 is mounted above the throttle slider 032 and meshes with the transmission gear 023 to ensure effective power transmission. When the driver accelerates, the throttle cable is pulled, causing the second connecting part 05 to move. The second connecting part 05 then moves the toothed throttle belt 031, causing the throttle slider 032 to slide along the first slide rail 015. The toothed throttle belt 031 meshes with the transmission gear 023, causing the transmission gear 023 to rotate. The rotation of the transmission gear 023 causes the brake sliding component 04 to move in the opposite direction, achieving acceleration.

[0036] Beneficial effects: The throttle toothed belt 031 and throttle slider 032 can slide on the first slide rail 015 according to the driver's operation, realizing the control of engine power output. This helps to improve driving smoothness and response speed. Because the throttle slider 032 and the first slide rail 015 are smoothly and continuously connected, compared with traditional cable or linkage mechanisms, it can more accurately control the engine power output and significantly reduce noise and vibration caused by mechanical movement.

[0037] In an optional embodiment, the brake sliding assembly 04 includes: a brake toothed band 041 and a brake slider 042; The brake toothed belt 041 is installed above the brake slider 042 and meshes with the transmission gear 023. One side of the brake toothed band 041 is connected to the third connecting part 07, and the other side is connected to the brake connecting rod 08.

[0038] The brake sliding assembly 04 consists of a brake toothed band 041 and a brake slider 042. The brake toothed band 041 is mounted above the brake slider 042 and meshes with the transmission gear 023. One side of the brake toothed band 041 is connected to the third connecting part 07, and the other side is connected to the brake connecting rod 08. When the driver performs a braking operation, the handbrake cable is pulled, causing the brake connecting rod 08 to move. The brake connecting rod 08 then moves the brake toothed band 041, causing the brake slider 042 to slide along the second slide rail 016. The brake toothed band 041 meshes with the transmission gear 023, causing the transmission gear 023 to rotate. The rotation of the transmission gear 023 causes the throttle toothed band 031 to move in the opposite direction to the throttle slider 032. During braking, the brake slider 042 is driven by the brake toothed band 041 to move along the second slide rail 016 to ensure the accuracy and stability of braking, thereby achieving deceleration.

[0039] In an optional embodiment, the first connecting part 05 includes: a first connecting rod 051, a first connecting cylinder 052, a first spring 053, and a first sliding bushing 054; The first connecting rod 051 is disposed on one side of the throttle toothed belt 031, and the engine throttle cable is connected to the first connecting rod 051; The first sliding bushing 054 is disposed on the first slide rail 015, and the first connecting cylinder 052 is mounted on the first sliding bushing 054; One end of the first spring 053 is disposed on the first connecting rod 051, and the other end is disposed in the first connecting cylinder 052.

[0040] The first connecting part 05 consists of a first connecting rod 051, a first connecting cylinder 052, a first spring 053, and a first sliding bushing 054. The first connecting rod 051 is located on one side of the throttle toothed belt 031 and is connected to the engine throttle cable. The first sliding bushing 054 is mounted on the first slide rail 015, and the first connecting cylinder 052 is mounted on the first sliding bushing 054, providing space for the installation and compression of the first spring 053. When no acceleration operation is performed, the throttle is turned on, the first spring 053 is in its natural state, and the first connecting rod 051 and the first connecting cylinder 052 maintain a certain distance through the first spring 053. When the driver accelerates, the throttle cable is pulled, which moves the second connecting part 06. The second connecting part 06 moves the throttle toothed belt 031 and the throttle slider 032. The throttle toothed belt 031 moves the first connecting rod 051, pulling the engine throttle cable, causing the engine throttle cable to move along the direction of the throttle toothed belt 031. Since the first connecting rod 051 and the first connecting cylinder 052 are connected by the first spring 053, the first connecting cylinder 052 and the first sliding sleeve 054 are also subjected to tension and slide along the first slide rail 015. During the sliding process, the first spring 053 is stretched and stores elastic potential energy. When the driver releases the throttle lever, the throttle cable is released, the first spring 053 releases the stored elastic potential energy, pulling the first connecting rod 051 and the first connecting cylinder 052 back to the initial position. The engine throttle cable no longer applies tension to the first connecting rod 051, and the engine stops accelerating.

[0041] Beneficial effects: The first connecting part 05, through the direct connection of the first connecting rod 051 to the engine throttle cable, ensures the precision of throttle operation. The driver's operations are transmitted to the throttle toothed belt 031 via the second connecting part, and then to the first connecting rod 051. The first connecting rod 051 drives the engine throttle cable, achieving control of engine power output. The first spring 053 provides a return function for the first connecting part 05. When the driver releases the throttle lever, the first spring 053 can quickly release its stored elastic potential energy, pulling the first connecting rod 051 back to its initial position, ensuring that the throttle system can quickly return to its natural state.

[0042] In an optional embodiment, the second connecting part 06 includes: a second connecting rod 061, a second connecting cylinder 062, a second spring 063, and a second sliding bushing 064; The second connecting rod 061 is disposed on one side of the throttle toothed belt 031, and the handle throttle cable is connected to the second connecting rod 061; The second sliding bushing 064 is disposed on the first slide rail 015, and the second connecting cylinder 062 is disposed in the second sliding bushing 064; The second spring 063 is disposed in the second connecting cylinder 062.

[0043] The second connecting rod 061 is connected to the toothed throttle belt 031, and the throttle cable is connected to the second connecting rod 061. When the driver accelerates, pulling the throttle cable moves the second connecting rod 061, which in turn moves the toothed throttle belt 031 and the throttle slider 032. The toothed throttle belt 031 moves the first connecting rod 051, simultaneously rotating the transmission gear 023. The second connecting cylinder 062 is located within the second sliding sleeve 064, and the second spring 063 is housed inside the second connecting cylinder 062. The second connecting cylinder 062 provides a stable installation environment and compression space for the second spring 063. When no external force is applied, the second spring 063 is in its natural state, and the second connecting rod 061, the second sliding sleeve 064, and the second connecting cylinder 062 remain relatively stationary. When the driver accelerates, pulling the throttle cable transmits the tension to the second connecting rod 061, causing it to move. At this time, the second spring 063 will be compressed to a certain extent, thereby storing elastic potential energy. When the driver releases the lever, the tension of the lever throttle cable is released, and the second spring 063 will use its stored energy to push the second connecting rod 061, so that the second connecting rod 061 returns to its initial position, forming a closed-loop feedback mechanism.

[0044] Beneficial effects: The second spring 063 provides a reset function for the second connecting part 06. When the driver releases the lever, the tension in the lever throttle cable is released, and the second spring 063 can push the second connecting rod 061 to reset, ensuring that the throttle can quickly return to its initial state. This helps improve stability and reduce safety hazards caused by improper operation. At the same time, the cushioning effect of the second spring 063 reduces wear caused by impacts, helping to extend its service life.

[0045] In an optional embodiment, the second connecting portion 06 further includes an adjusting screw 065; The adjusting screw 065 has a through hole; The second connecting rod 061 passes through the through hole and is connected to the throttle toothed belt 031; The second connecting cylinder 062 is provided with an internal thread, and the adjusting screw 065 is threadedly connected to the internal thread of the second connecting cylinder 062. One end of the second spring 063 is disposed on the second connecting rod 061, and the other end is connected to the adjusting screw 065. The adjusting screw 065 is used to adjust the stroke of the second spring 063.

[0046] The second connecting rod 061 passes through the through hole of the adjusting screw 065 and is directly connected to the throttle toothed belt 031. The throttle cable is connected to the second connecting rod 061. When the driver accelerates, pulling the throttle cable moves the second connecting rod 061, which in turn moves the throttle toothed belt 031 and the throttle slider 032. As the second connecting rod 061 moves, it passes through the adjusting screw 065, compressing the second spring 063 within the second connecting cylinder 062 and accumulating elastic potential energy. When the driver releases the throttle, the throttle cable is released, and the second spring 063 uses its stored energy to push the second connecting rod 061 back to its original position. The adjusting screw 065 is threaded into the internal thread of the second connecting cylinder 062, allowing adjustment within the cylinder. One end of the second spring 063 rests against the second connecting rod 061, and the other end is connected to the bottom of the adjusting screw 065. When the position of adjusting screw 065 changes, it directly affects the compression degree of the second spring 063, thus altering its stroke. When no external force is applied, the second spring 063 is in a certain pre-compression state to maintain throttle stability and response speed. When it is necessary to adjust the throttle feedback time, its position in the second connecting cylinder 062 can be changed by rotating adjusting screw 065. Rotating adjusting screw 065 downwards will cause the second spring 063 to undergo greater compression, thereby increasing its generated pressure; rotating adjusting screw 065 upwards will decrease the compression degree of the second spring 063, reducing its pressure.

[0047] Beneficial effects: Adjusting screw 065 allows for flexible adjustment of the pressure of the second spring 063. Drivers or maintenance personnel can change the spring compression by rotating adjusting screw 065 according to actual needs, thereby adjusting the throttle travel and acceleration response to better suit driving habits and road conditions. Adjusting the spring pressure via adjusting screw 065 optimizes throttle power output.

[0048] In an optional embodiment, the third connecting part 07 includes: a third connecting rod 071, a third connecting cylinder 072, a third spring 073, a third sliding bushing 074, and a connecting port 075; The third connecting rod 071 is disposed on one side of the brake toothed band 041; The third sliding bushing 074 is disposed on the second slide rail 016, and the third connecting cylinder 072 is installed in the third sliding bushing 074; One end of the third spring 073 is connected to the third connecting rod 071, and the other end of the third spring 073 is connected to the third connecting cylinder 072; The third connecting cylinder 072 has a connecting port 075 on one side, and the brake disc brake cable is connected to the connecting port 075.

[0049] In an optional embodiment, the third connecting portion further includes a fixing pin 076; The third connecting rod 071 is provided with a pin groove; The third connecting cylinder 072 is provided with a pin hole adapted to the fixing pin 076, and the fixing pin 076 connects the third connecting rod 071 to the third connecting cylinder 072 through the pin hole and the pin groove; When the third connecting rod 071 moves toward the third connecting cylinder 072, the stroke of the third spring 073 is compressed. When the handbrake is pressed, the brake connecting rod 08 is driven by the handbrake cable, the brake slider 042 moves toward the brake connecting rod 08, the third spring 073 is reset, and the fixing pin 076 is used to prevent the third connecting rod 071 from coming out of the third connecting cylinder 072.

[0050] One end of the third connecting rod 071 is connected to the brake toothed band 041, and the other end is located inside the third connecting cylinder. A fixing pin 076 passes through the pin hole on the third connecting cylinder 072 and is inserted into the pin groove on the third connecting rod 071, allowing the third connecting rod 071 to be installed inside the third connecting cylinder 072. The third sliding bushing 074 is installed on the second slide rail 016, and the third connecting cylinder 072 is installed inside the third sliding bushing 074. One end of the third spring 073 is connected to the third connecting rod 071, and the other end is connected to the third connecting cylinder 072. In its natural state, the third spring 073 maintains a certain preload, ensuring the response speed of the braking system. The connection port 075 is located on one side of the third connecting cylinder 072, and the brake disc brake cable is connected to the brake disc brake cable through the connection port 075. When the driver presses the handbrake, the handbrake cable drives the brake connecting rod 08, which in turn moves the brake toothed band 041 and the brake slider 042. The brake toothed band 041 then moves the third connecting rod 071. At the same time, the transmission gear 023 is driven to rotate, and the transmission gear 023 drives the throttle toothed belt 031 and the throttle slider 032 to move in opposite directions. The throttle toothed belt 031 drives the first connecting rod 051 and the second connecting rod 061 to move, pull back the throttle cable of the handle, and stop the acceleration operation.

[0051] Beneficial effects: The third connecting rod 071 moves towards the brake toothed band 041, causing the third connecting cylinder 072 and the third sliding bushing 074 to move. When the third sliding bushing 074 moves, it pulls the brake disc and brake cable, causing the brake disc to generate friction and slowing down the wheel speed, thus achieving the braking function. When the driver releases the handbrake, the first spring 053 releases its elastic potential energy, causing the first connecting rod 051 to return to its natural state. When the first connecting rod 051 moves, it pushes the throttle toothed band 031 to move. The throttle toothed band 031 drives the transmission gear 023 to rotate, and the transmission gear 023 drives the brake toothed band 041 to return to the preset position. The brake toothed band 041 drives the brake connecting rod 08 and the third connecting rod 071 to move. When the third connecting rod moves, it pushes the third spring 073. The third spring 073 uses its elastic force to push the third connecting cylinder 072 and the third connecting bushing 074 back to the preset position. The release of elastic force is also the process of the braking system releasing braking force, allowing the wheels to rotate again.
