Description

Technical Field

[0001] This utility model relates to the technical field of electric vehicle brake rocker arm structure, and more specifically to a multifunctional brake rocker arm structure. Background Technology

[0002] In a vehicle, the rocker arm acts essentially as a lever, primarily used to change the direction of force transmission. In electric bicycles, due to their lower torque and limited speed, the rocker arm is typically used to change the braking line and work in conjunction with the brake shoes for braking. The ratio of the arm lengths on both sides of the rocker arm is called the rocker arm length. Existing rocker arms can only perform a single function and cannot control the indicator light switch that works in conjunction with the brakes. Therefore, a control switch needs to be installed in a specific location to enable control. However, when the vehicle is running, water splashed from the tires can cause water to enter the power-off switch, causing it to malfunction and preventing the indicator light from illuminating properly, increasing subsequent maintenance costs. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a multi-functional braking rocker arm structure. This utility model changes the original rocker arm structure and lengthens the rocker arm, reducing production costs. At the same time, it adds a power-off arm, making one arm multi-functional, saving production costs, protecting the power-off switch, extending service life, and effectively reducing maintenance costs.

[0004] The purpose of this utility model is achieved through the following technical solution: a multi-functional braking rocker arm structure, including a first rocker arm plate and a second rocker arm plate. The first rocker arm plate includes a first fixed plate, a first inclined plate, and a first pull wire plate, which are connected in sequence. The second rocker arm plate includes an indicator light arm, a second fixed plate, a second inclined plate, and a second pull wire plate, which are connected in sequence. The second rocker arm plate is shaped like the number 7. The first and second fixed plates are provided with mounting holes that pass through them. The first and second fixed plates have the same shape and are fixedly connected by rivets. The first and second inclined plates have the same shape and have a certain angle between them. The first and second pull wire plates have the same shape and are provided with hinge holes at corresponding positions. The first and second pull wire plates are parallel to each other. The indicator light arm is provided with a tension spring hole. The length of the first rocker arm plate is 140-150cm.

[0005] In one preferred embodiment, the length of the first rocker arm plate is 140cm.

[0006] In one preferred embodiment, the first fixing plate has a first positioning hole at the end near the first inclined plate, and the second fixing plate has a second positioning hole corresponding to the first positioning hole.

[0007] The beneficial effects of this utility model are as follows: This utility model designs the rocker arm as a combined structure, which not only realizes the function of the rocker arm, but also reduces the manufacturing cost by connecting it to the indicator light arm through the tension spring. During the braking process, the indicator light can be controlled at the same time, and the power-off switch can be installed in a higher position, thereby preventing water splashed from the tires onto the power-off switch and effectively protecting the power-off switch. Furthermore, by lengthening the rocker arm, the stroke is increased, and when the brake pads are worn to a certain extent, the tension of the cable can be adjusted to ensure normal braking, effectively improving the utilization rate of the brake pads and significantly reducing the subsequent maintenance costs of the vehicle.

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0012] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0013] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0014] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", 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 utility model product is in use. They are only for the convenience of describing this utility model 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 utility model.

[0015] The terms “first,” “second,” “third,” etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0016] The terms "parallel" and "perpendicular" do not mean that the components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that its direction is more parallel than "perpendicular," not that the structure must be completely parallel, but that it can be slightly tilted.

[0017] The terms "horizontal," "vertical," and "sag" do not imply that a component must be absolutely horizontal, vertical, or sagging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

[0018] Furthermore, terms like "roughly" and "basically" are used to indicate that the content does not require absolute precision, but rather allows for a certain degree of deviation. For example, "roughly equal" does not simply mean absolute equality; in actual production and operation, achieving absolute "equality" is difficult, and a certain degree of deviation is generally present. Therefore, besides absolute equality, "roughly equal to" also includes the aforementioned situation where a certain degree of deviation exists. Using this as an example, in other cases, unless otherwise specified, terms like "roughly" and "basically" have similar meanings.

[0019] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] See Figure 1This utility model provides a technical solution: a multi-functional braking rocker arm structure, including a first rocker arm plate 1 and a second rocker arm plate 2. The first rocker arm plate 1 includes a first fixing plate 11, a first inclined plate 12, and a first pull cable plate 13, which are connected in sequence. The second rocker arm plate 2 includes an indicator light lever arm 21, a second fixing plate 22, a second inclined plate 23, and a second pull cable plate 24, which are connected in sequence. The second rocker arm plate 2 has a specific shape. The first fixed plate 11 and the second fixed plate 22 are shaped like the number 7. They are provided with mounting holes 3 that pass through them. The first fixed plate 11 and the second fixed plate 22 have the same shape and are fixedly connected by rivets. The first inclined plate 12 and the second inclined plate 23 have the same shape and have a certain angle between them. The first pull plate 13 and the second pull plate 24 have the same shape and are provided with hinge holes 4 at corresponding positions. The first pull plate 13 and the second pull plate 24 are parallel to each other. The indicator light lever arm 21 is provided with tension spring holes 5. The length of the first rocker arm plate 1 is 140-150cm. This utility model designs the rocker arm as a combined structure, which not only realizes the function of a rocker arm, but also connects to the indicator light lever arm 21 through a tension spring, so that the indicator light can be controlled simultaneously during braking. It can also install the power cut-off switch in a higher position, thereby preventing water splashed from the tires onto the power cut-off switch and effectively protecting the power cut-off switch. Furthermore, the length of the rocker arm is increased to increase its stroke. When the brake pads are worn to a certain extent, the tension of the cable can be adjusted to ensure normal braking, effectively improving the utilization rate of the brake pads and significantly reducing the subsequent maintenance costs of the vehicle.

[0021] Preferably, the length of the first rocker arm plate 1 is 140cm.

[0022] Preferably, the first fixing plate 11 has a first positioning hole 6 at its end near the first inclined plate 12, and the second fixing plate 22 has a second positioning hole corresponding to the first positioning hole 6. This facilitates positioning when the first fixing plate 11 and the second fixing plate 22 are riveted together, and avoids misalignment.
