Description

Technical Field

[0001] This utility model relates to the field of braking mechanism technology, and in particular to an auxiliary parking mechanism. Background Technology

[0002] The parking brake on electric vehicles or motorcycles serves as an auxiliary braking mechanism, and its parking function is crucial. This function, through a switch-lock mechanism, keeps the brake lever engaged even when the driver releases it. This feature acts as a safety measure when parking on a slope or waiting at a traffic light, functioning similarly to a car's handbrake, providing a safe parking experience.

[0003] Currently, most motorcycles and electric vehicles achieve parking functionality by adding an auxiliary parking mechanism to the original brake lever. Existing auxiliary parking mechanisms on the market primarily use bolts to lock themselves into the threaded holes of the brake lever. To use the parking function, first squeeze the brake lever, then press the auxiliary parking mechanism, and then release the brake lever. The brake lever will spring back and rest against the auxiliary parking mechanism, thus parking the vehicle.

[0004] However, this method relies solely on tightening the fixing bolts, resulting in low stability. When using the parking function, the impact force generated by the rebound of the brake lever can easily cause the auxiliary parking mechanism to shift. Once shifted, the expected parking effect cannot be achieved, posing a safety hazard to vehicle use. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary parking mechanism that solves the problem of poor parking effect of existing auxiliary parking mechanisms and provides a more stable and reliable parking effect.

[0006] To achieve the above objectives, the solution of this utility model is: an auxiliary parking mechanism, used in conjunction with a brake lever pivotally connected to a handle mounting seat, characterized in that: the auxiliary parking mechanism includes a fixed seat, a sliding component, and a limiting block; the fixed seat is fixed on the handle mounting seat, the sliding component is slidably disposed on the fixed seat, and its inner end is connected to the limiting block, and the limiting block is driven to perform corresponding actions by its own movement;

[0007] When the brake lever is in the braking state, there is a brake gap between the brake lever located at the inner end of the pivot and the lever mounting seat; the sliding component moves forward or backward under the action of external force to reset, causing the limit block to horizontally insert into or disengage from the brake gap, thereby locking or unlocking the brake lever.

[0008] Furthermore, the fixed base is provided with a horizontal groove for the sliding component to slide.

[0009] Furthermore, the inner end of the sliding rod is a large-diameter end, and the outer end is a small-diameter end, with a first annular boss formed at the connection between the large-diameter end and the small-diameter end;

[0010] The shape of the groove on the fixed seat matches the shape of the sliding rod. The groove has a large-diameter groove and a small-diameter groove. The connection between the large-diameter groove and the small-diameter groove forms a second annular boss. The first annular boss and the second annular boss limit each other to prevent the sliding rod from coming out of the outer end of the groove.

[0011] Furthermore, the sliding assembly includes a sliding rod and a bolt sleeve. The sliding rod is slidably mounted on the fixed base. A first connecting hole is provided at the inner end of the sliding rod, and a second connecting hole is provided on the limiting block. The bolt sleeve cooperates with the first connecting hole and the second connecting hole to connect the sliding rod to the limiting block.

[0012] Furthermore, the limiting block is L-shaped, with its vertical end fixedly connected to the sliding component and its horizontal end movably engaged with the brake handle.

[0013] Furthermore, the outer end of the limiting block has a hook, and the inner end of the brake handle has a locking block. When the limiting block is embedded in the brake gap and contacts the brake handle, the hook on it engages with the locking block of the brake handle to restrict the limiting block from disengaging from the brake gap and to lock the brake handle.

[0014] Furthermore, an elastic reset member is provided between the sliding component and the fixed base, which is used for the reverse reset of the sliding component and the limiting block.

[0015] Furthermore, the inner end of the fixed base extends horizontally inward to form a guide portion, and the limiting block is slidably engaged with the guide portion. Correspondingly, the inner end of the limiting block forms a U-shaped opening groove, and the upper and lower ends of the U-shaped opening groove are engaged with the guide portion and can slide horizontally along the guide portion.

[0016] A clearance groove is provided in the middle of the guide section, and the bolt sleeve passes through the clearance groove to connect with the limit block.

[0017] Furthermore, the outer end of the fixed base is provided with an additional mounting hole, which is coaxial with the pivot joint of the brake handle. During installation, the connecting component is used to cooperate with the additional mounting hole and the original mounting hole of the handle mounting base to realize the connection between the brake handle and the handle mounting base.

[0018] Furthermore, the outer end of the sliding rod is provided with a lever assembly, which includes a vertically arranged lever and a pin and a clamp for fixing the lever.

[0019] After adopting the above solution, the beneficial effects of this utility model are as follows:

[0020] The auxiliary parking mechanism includes a fixed seat, a sliding component, and a limiting block. When the brake lever is in the braking state, there is a brake gap between the brake lever located at the inner end of the pivot and the lever mounting seat. When the sliding component is subjected to external force, it moves forward or backward to reset, causing the limiting block to horizontally engage or disengage from the brake gap, thereby locking or unlocking the brake lever.

[0021] In this design, the limiting block enters the brake gap horizontally. The rebound impact direction of the brake lever is different from the movement path of the limiting block; in fact, the rebound impact direction may even clamp the limiting block tighter. Therefore, the rebound impact of the brake lever will not affect the limiting block, nor will it cause displacement of the mounting bracket, thus not affecting the parking effect.

[0040] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] This utility model provides an auxiliary parking mechanism that works in conjunction with the brake handle 1 pivotally connected to the handle mounting seat 2 to help the brake handle 1 lock, so that it can stably maintain the braking state, or quickly unlock when needed to restore the normal operation of the brake handle 1.

[0042] like Figures 1 to 9 As shown, the auxiliary parking mechanism includes a fixed base 3, a sliding assembly, a limiting block 6, and an elastic reset component 7. The fixed base 3 is fixed to the handlebar mounting base 2 via a connecting assembly 10. The sliding assembly is slidably mounted on the fixed base 3, with its inner end connected to the limiting block 6. Its movement drives the limiting block 6 to perform corresponding actions. When the brake lever 1 is in the braking state, a brake gap 8 exists between the brake lever 1 at the inner end of the pivot and the handlebar mounting base 2. (Refer to...) Figure 9 The brake gap 8 is the key to the auxiliary braking in this solution. When the sliding component is subjected to external force, it can move forward or backward to reset, thereby driving the limiting block 6 to move horizontally, so that it can be inserted into or disengaged from the brake gap 8, thus locking or unlocking the brake handle 1.

[0043] To further improve the ease of installation and reduce the difficulty and cost of user modification, this solution installs the mounting bracket 3 and the brake lever 1 in the same position as the handle mounting bracket 2. Specifically: Figure 2 and Figure 3As shown, the outer end of the mounting base 3 has a mounting hole 31, which is coaxial with the pivot point of the brake handle 1. The connecting assembly 10 selected in this application includes a fixing bolt 101, a bushing 102, and a fixing nut 103. During installation, the fixing bolt 101 is passed through the mounting hole 31 and the original mounting hole of the handle mounting base 2, and then locked with the fixing nut 103 to fix the brake handle 1 to the handle mounting base 2. The mounting base 3 is horizontally mounted relative to the brake handle 1, providing horizontal support and guidance for the sliding assembly and the limiting block 6.

[0044] The sliding component and the limiting block 6 can be designed as an integrated structure, or they can be designed as separate structures. A separate structure allows for disassembly and assembly, facilitating replacement and maintenance, and is the preferred solution in this application. Figure 2 and Figure 3 As shown, the sliding assembly includes a sliding rod 4 and a bolt sleeve 5. The sliding rod 4 is a cylindrical structure with different diameters, its inner end being a large-diameter end and its outer end being a small-diameter end, with a first annular boss 41 formed at the connection between the large-diameter end and the small-diameter end. A horizontal groove 32 for sliding of the sliding component is provided on the fixed base 3. The shape of the groove 32 matches the shape of the sliding rod 4, such as... Figure 3 As shown, the slide groove 32 has a large-diameter groove and a small-diameter groove, and a second annular boss 33 is formed at the connection between the large-diameter groove and the small-diameter groove. The first annular boss 41 and the second annular boss 33 mutually limit each other. When the sliding rod 4 slides in the slide groove 32, the first annular boss 41 and the second annular boss 33 can effectively prevent the sliding rod 4 from coming out of the outer end of the slide groove 32.

[0045] The inner end of the sliding rod 4 is connected to the limiting block 6 via a bolt sleeve 5. For example... Figure 2 and Figure 3 As shown, the inner end of the sliding rod 4 has a first connecting hole 42, and the limiting block 6 has a corresponding second connecting hole 61. In this embodiment, the bolt assembly 5 includes an externally threaded bolt 51 and an internally threaded bolt 52, wherein one bolt is engaged in the first connecting hole 42, and the other bolt is engaged in the second connecting hole 61. The two bolts are then locked together by threads to achieve the connection between the sliding rod 4 and the limiting block 6. Of course, in practical applications, other common combinations such as bolts and nuts can also be used to achieve the connection. This application does not strictly limit this, and users can flexibly choose according to specific needs and usage scenarios.

[0046] like Figure 2 and Figure 3As shown, the limiting block 6 is designed in an L-shape. This L-shaped structure has clear functional divisions. The vertical end of the L-shaped limiting block 6 is fixedly connected to the sliding component, providing stable support and accurate positioning for the entire limiting block 6. The horizontal end of the L-shaped limiting block 6 is movable and cooperates with the brake lever 1, playing a key role in realizing the parking and unlocking functions. When the horizontal end of the limiting block 6 is inserted into the brake gap 8, and the brake lever 1 is released, it can clamp the limiting block 6. At the same time, the inner end of the brake lever 1 is pushed by the limiting block 6, realizing the parking function of the vehicle. If the brake lever 1 is squeezed tighter, the limiting block 6 will lose the clamping force of the brake lever 1. At this time, the limiting block 6 can slide freely out of the brake gap 8, and the vehicle is released from parking.

[0047] To further improve parking stability, this design incorporates a snap-fit ​​structure. Specifically, the outer end of the horizontal end of the limiting block 6 has a hook 62, such as... Figure 2 and Figure 3 As shown, the inner end of the brake lever 1 has a locking block 11. When the limiting block 6 is inserted into the brake gap 8 and the brake lever 1 is released, the hook 62 can engage with the locking block 11. In this way, even if a large pulling force is applied to the locking block 11, it is difficult to break through the locking structure and dislodge the limiting block 6 from the brake gap 8, thereby achieving a stable lock of the brake lever 1.

[0048] An elastic reset element 7 is provided between the sliding component and the fixed base 3. The elastic reset element 7 is used for the reverse reset of the sliding component and the limiting block 6, thereby realizing the automatic unlocking of the brake handle 1. In this solution, the elastic reset element 7 is preferably a reset spring, such as... Figure 5 As shown, the return spring is sleeved on the small-diameter end of the sliding rod 4. The inner end of the return spring abuts against the first annular boss 41 of the sliding rod 4, while the outer end abuts against the second annular boss 33 of the sliding groove 32. When the sliding assembly moves forward under the action of external force, causing the limiting block 6 to engage with the brake gap 8 to achieve parking, the return spring is compressed and stores elastic potential energy. When unlocking is required, the external force disappears, and the return spring releases the stored elastic potential energy, pushing the sliding assembly to move in the opposite direction, causing the limiting block 6 to automatically disengage from the brake gap 8, thereby achieving automatic unlocking of the brake lever 1.

[0049] In addition, the aforementioned snap-fit ​​structure can precisely counteract the restoring force of the return spring, preventing the limit block 6 from being pulled out of the brake gap 8 in the parking state, thus avoiding brake failure.

[0050] To improve the sliding stability of the limit block 6, the structure of the fixed base 3 was further optimized. For example... Figures 2 to 4As shown, the inner end of the fixed base 3 extends horizontally inward to form a guide portion 34. Correspondingly, the vertical end of the limiting block 6 forms a U-shaped opening groove 63, the size and shape of which match the guide portion 34. The upper and lower ends of the U-shaped opening groove 63 are engaged with the guide portion 34. When the limiting block 6 slides horizontally under the drive of the sliding component, the U-shaped opening groove 63 moves smoothly along the guide portion 34. This engaging method effectively avoids instability such as shaking or offset of the limiting block 6 during sliding, greatly improving the smoothness and accuracy of the sliding of the limiting block 6. At the same time, in order to meet the connection requirements between the sliding rod 4 and the limiting block 6 without affecting the sliding of the limiting block 6, a racetrack-shaped clearance groove 35 is provided in the middle of the guide portion 34. The bolt sleeve 5 passes through the clearance groove 35 and connects to the limiting block 6. The racetrack-shaped design ensures that the clearance groove 35 has enough space for the bolt sleeve 5 to pass through, while also reasonably limiting the range of movement of the bolt sleeve 5, thus preventing components such as the sliding rod 4 from coming out of the inner end of the groove 32.

[0051] To facilitate easier and more efficient operation of the sliding rod 4, this design adds a vertical lever assembly 9 to the outer end of the sliding rod 4. This assembly mainly consists of three key components: a lever 91, a pin 92, and a clamp 93. Figure 3 As shown, the lower end of the lever 91 has a downward-facing U-shaped keyway 911. First through holes 912 are formed on both the front and rear sides of the U-shaped keyway 911. The outer end of the sliding rod 4 forms a rectangular key 43 that can be embedded in the U-shaped keyway 911. A second through hole 44 corresponding to the first through hole 912 is formed in the middle of the rectangular key 43. The U-shaped keyway 911 of the lever 91 is vertically inserted into the rectangular key 43, aligning the first through hole 912 and the second through hole 44. Then, the pin 92 passes through the first through hole 912 and the second through hole 44 from one side, and is secured in the annular groove 921 of the pin 92 on the other side using a clamp 93, thus connecting the lever 91 and the sliding rod 4. In actual operation, as... Figure 4 and Figure 5 As shown, the user can slide the slider 4 outward by flicking the lever 91 outward with their finger, which is convenient and effortless.

[0052] The braking principle of the auxiliary parking mechanism of this utility model is as follows:

[0053] When the vehicle needs to activate the parking function, the driver first squeezes the brake lever 1, then moves the lever 91 by hand, pulling the sliding rod 4 outwards, so that the lever slides smoothly outwards until the limit block 6 enters the brake gap 8 (by...). Figure 6 Towards Figure 7 Change, and by Figure 9(Move towards the dotted line), then release the brake lever 1. The brake lever 1 clamps the limit block 6, and the hook 62 and the block 11 engage with each other, thereby realizing the vehicle's parking function.

[0054] When it is necessary to release the parking state, the driver only needs to squeeze the brake lever 1 again. At this time, the brake lever 1 disengages from the limit block 6, the clamping force on the limit block 6 disappears, and the sliding rod 4 slides inward under the restoring force of the return spring, causing the limit block 6 to disengage from the brake gap 8, and the brake lever 1 is unlocked. At this time, when the lever is released, the brake lever 1 will return to its initial position under the action of its own reset mechanism, and the vehicle is released from parking.
