Description

Technical Field

[0001] This utility model relates to the field of brake control structure technology, specifically a circular brake control structure for electric vehicles. Background Technology

[0002] Electric bicycles are mechatronic personal transportation vehicles that use batteries as auxiliary power and are based on ordinary bicycles. They are equipped with motors, controllers, batteries, throttles, brake levers, and display systems. Currently, electric bicycles use hand brakes. When using them, we need to stop the vehicle at traffic lights. If the road is on a slope, we need to hold the brake lever tightly to stop the vehicle, which puts a lot of strain on the hands and does not meet current usage requirements.

[0003] Existing technology, such as announcement number CN212313787U, provides an electric vehicle braking assistance device, including a brake lever and a bracket for controlling the brake. The brake lever is hinged to the bracket via hinge axis A. The bracket is mounted on the handlebars. The bracket is also equipped with an auxiliary device, which is used to lock the brake lever when braking, so that the electric vehicle remains in a braking state when the user's hand is removed from the brake lever. This utility model has a novel structure, is simple to operate, and is convenient to use. It can realize the function of assisted braking and parking, and meets current usage requirements.

[0004] In the current design, the linkage component and locking element are used. When the brake lever is gripped, it rotates, causing the linkage component to move synchronously. When a stop is needed, the locking element is inserted into the linkage component, locking it in place and preventing the brake lever from returning to its original position, thus achieving the stopping function. However, in practical use, the user needs to grip the brake lever while simultaneously using their fingers to insert the locking element into the linkage component. Since the locking element limits movement through insertion, the user needs a certain degree of dexterity and skill to operate it, resulting in limitations in usability. Therefore, we propose a circular brake control structure for electric vehicles. Utility Model Content

[0005] The purpose of this utility model is to provide a circular brake control structure for electric vehicles. This circular brake control structure solves the problem that electric bicycles use hand-held brakes, which put a lot of strain on the hands when stopping the vehicle at traffic lights or on slopes.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A circular brake control structure for an electric vehicle includes a connecting sleeve, one end of which is rotatably provided with a handle, and a connecting rotating head is fixedly connected to the end of the connecting sleeve near the handle. The connecting rotating head is rotatably connected to a rotating groove opened in the inner wall of the connecting sleeve.

[0008] The outer wall of the connecting sleeve is rotatably connected to a winding disc via a support block for winding the brake cable. A driven wheel is fixedly connected to one side of the winding disc, and a driving wheel is meshed with the outer wall of the driven wheel. The driving wheel is fixedly sleeved on the handle.

[0009] Preferably, the inner wall of the handle is provided with a piston groove, and a support rod is fixedly connected to one end of the connecting head at the piston groove. A first end face ratchet is fixedly connected to the end of the support rod away from the connecting head, and a second end face ratchet is radially slidably connected to the outer wall of the support rod at the position between the first end face ratchet and the connecting head.

[0010] Preferably, the first end face ratchet and the second end face ratchet cooperate with each other, and a spring is movably sleeved on the outer wall of the support rod at the position between the second end face ratchet and the connecting head.

[0011] Preferably, a piston is slidably connected to the inner wall of the piston groove, and a connecting rod is fixedly connected to the end of the piston near the first end face ratchet, and the connecting rod is fixedly connected to the second end face ratchet through a connecting ring.

[0012] Preferably, the handle has a through groove in the finger area when the hand grips the handle, and the inner wall of the through groove is slidably connected to a pressure block.

[0013] Preferably, a limiting block is fixedly connected to one side of the pressurizing block inside the piston groove.

[0014] Preferably, the outer wall of the handle is fixedly fitted with a rubber sleeve, and the outer wall of the rubber sleeve has anti-slip texture.

[0015] By employing the above technical solution, this utility model provides a circular brake control structure for electric vehicles. It possesses at least the following beneficial effects:

[0016] 1. When braking is required, this utility model rotates the handle to drive the drive wheel to rotate, and then drives the winding disc to rotate and tighten the brake cable through the meshing driven wheel, thus achieving the braking effect. Compared with the conventional handbrake, which requires releasing some fingers to press the brake lever, this method has higher safety and does not require releasing some fingers to press the brake lever, making the hand grip on the handle more secure.

[0017] II. This utility model, by setting a support rod on the connecting head to connect the first end face ratchet, allows the second end face ratchet to be pushed against the first end face ratchet under the action of spring tension, thus limiting the rotation angle of the handle and facilitating the braking state when the hand leaves the handle. When the hand grips the handle, the fingers will press the pressure block into the piston groove, increasing the pressure in the piston groove and thus pushing the piston. The connecting ring on the connecting rod pulls the second end face ratchet away from the first end face ratchet, thereby releasing the limit. This achieves the purpose of automatic limit when the hand is released and release of the limit when the hand is pressed. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 - Figure 4As shown, a circular brake control structure for an electric vehicle includes a connecting sleeve 1. A handle 2 is rotatably mounted on one end of the connecting sleeve 1. A connecting head 11 is fixedly connected to one end of the connecting sleeve 1 near the handle 2. The connecting head 11 is rotatably connected to a rotating groove 21 opened in the inner wall of the connecting sleeve 1. A winding disc 3 is rotatably connected to the outer wall of the connecting sleeve 1 via a support block 31 for winding the brake cable. A driven wheel 32 is fixedly connected to one side of the winding disc 3. A driving wheel 33 is meshed with the outer wall of the driven wheel 32 and is fixedly mounted on the handle 2.

[0026] In this embodiment, when braking is required, the drive wheel 33 is rotated by turning the handle 2, and then the winding disc 3 is rotated by the meshing driven wheel 32 to tighten the brake cable, thus achieving the braking effect. Compared with the conventional handbrake method that requires releasing some fingers to press the brake lever, it has higher safety, and does not require releasing some fingers to press the brake lever, making the hand grip the handle 2 more secure.

[0027] like Figure 2 , Figure 3 , Figure 4 As shown, preferably, the inner wall of the handle 2 is provided with a piston groove 22. A support rod 4 is fixedly connected to one end of the connecting head 11 at the position of the piston groove 22. A first end face ratchet 41 is fixedly connected to the end of the support rod 4 away from the connecting head 11. A second end face ratchet 42 is radially slidably connected to the outer wall of the support rod 4 at the position between the first end face ratchet 41 and the connecting head 11. The first end face ratchet 41 and the second end face ratchet 42 cooperate with each other. A spring 43 is movably sleeved on the outer wall of the support rod 4 at the position between the second end face ratchet 42 and the connecting head 11. A piston 45 is slidably connected to the inner wall of the piston groove 22. A connecting rod 46 is fixedly connected to the end of the piston 45 near the first end face ratchet 41. The connecting rod 46 is fixedly connected to the second end face ratchet 42 through a connecting ring 44. A through groove 23 is provided in the finger area when the hand grips the handle 2. A pressure block 24 is slidably connected to the inner wall of the through groove 23.

[0028] In this embodiment, by setting a support rod 4 on the connecting head 11 to connect the first end face ratchet 41, the second end face ratchet 42 can be pushed against the first end face ratchet 41 under the tension of the spring 43 to limit the rotation angle of the handle 2, so as to keep the brake state when the hand leaves the handle 2. When the hand grips the handle 2, the fingers will press the pressure block 24 into the piston groove 22, which will increase the pressure of the piston groove 22, thereby pushing the piston 45. The connecting ring 44 on the connecting rod 46 pulls the second end face ratchet 42 to separate from the first end face ratchet 41, thereby releasing the limit and achieving the purpose of automatic limit when the hand is released and release of the limit when the hand is pressed.

[0029] like Figure 1, Figure 4 As shown, preferably, a limiting block is fixedly connected to one side of the pressure block 24 inside the piston groove 22 to prevent the pressure block 24 from disengaging from the through groove 23. A rubber sleeve is fixedly fitted on the outer wall of the handle 2, and anti-slip texture is provided on the outer wall of the rubber sleeve to increase friction.

[0030] This utility model discloses a circular brake control structure for an electric vehicle. When braking is required, rotating the handle 2 drives the drive wheel 33 to rotate, which in turn drives the winding disc 3 to rotate and tighten the brake cable, thus achieving the braking effect. By setting a support rod 4 on the connecting head 11 to connect the first end face ratchet 41, the second end face ratchet 42 can be pushed against the first end face ratchet 41 under the tension of the spring 43 to limit the rotation angle of the handle 2, so as to maintain the braking state when the hand leaves the handle 2. When the hand grips the handle 2, the fingers will press the pressure block 24 into the piston groove 22, which increases the pressure in the piston groove 22, thereby pushing the piston 45. The connecting ring 44 on the connecting rod 46 pulls the second end face ratchet 42 to separate from the first end face ratchet 41, thereby releasing the limit. This achieves the purpose of automatic limit when the hand is released and release when the hand is pressed.
