Description

Technical Field

[0001] This utility model relates to the field of tricycle processing and manufacturing technology, and in particular to a junction box and a tricycle. Background Technology

[0002] In today's transportation industry, tricycles are often the preferred mode of transport for logistics companies due to their ability to carry a large amount of goods. Tricycles have a single steering wheel at the front and two sets of wheels symmetrically mounted at the rear.

[0003] Nowadays, tricycles are prone to significant risks during braking. If the left and right symmetrical rear wheels brake at different times during braking, the tricycle body will shift during braking, eventually causing the tricycle to overturn. This also increases the braking distance of the tricycle and reduces the safety of driving it. Utility Model Content

[0005] To achieve this objective, the present invention adopts the following technical solution: The present invention provides a junction box, including a hydraulic cylinder and a main body plate. The hydraulic cylinder is installed on one side of the main body plate, and a telescopic rod is installed inside the hydraulic cylinder. The hydraulic cylinder pushes the telescopic rod to move along the axis. An integrated block is installed inside the main body plate, and the telescopic rod pushes the integrated block to move. A first pull wire and a second pull wire are respectively connected to the two symmetrical sides of the integrated block.

[0008] Preferably, a second mounting groove is formed on the main body plate, and the integrated block is slidably mounted in the second mounting groove.

[0009] Preferably, the integrated block is triangular in shape, and a first insertion hole and a second insertion hole are formed on the symmetrical sides of the integrated block. A first connecting post is inserted into the first insertion hole, and a second connecting post is inserted into the second insertion hole.

[0011] Preferably, the integrated block is further provided with a third insertion hole and a third notch. The third notch is located in the middle section of the third insertion hole. A third connecting post is inserted into the third insertion hole. A third pull wire is installed inside the third connecting post. The third pull wire sways within the third notch.

[0012] Preferably, the third pull wire and the third connecting post are integrally formed.

[0013] Preferably, the junction box further includes a mounting cover, which is attached to the second mounting slot.

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0020] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between 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.

[0021] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0023] With current technology, the brakes of the left and right wheels of a tricycle may be independent of each other. If braking is required, the braking time needs to be manually controlled, which will lead to asynchronous braking timing. This will eventually cause the tricycle to skid or overturn, resulting in safety risks for the driver.

[0024] Example 1

[0025] To solve the above problems, such as Figures 1 to 2As shown, this utility model provides a junction box, including a hydraulic cylinder 1 and a main plate 2. The hydraulic cylinder 1 is installed on one side of the main plate 2, and a telescopic rod is installed inside the hydraulic cylinder 1. The hydraulic cylinder 1 pushes the telescopic rod to move along the axis. An integrated block 3 is installed inside the main plate 2. The telescopic rod pushes the integrated block 3 to move. A first pull wire 4 and a second pull wire 5 are respectively connected to the two symmetrical sides of the integrated block 3.

[0026] A tricycle typically consists of a frame with a left wheel and a right wheel mounted on each side. A front wheel is mounted on the front of the frame. A braking assembly is mounted on the frame and is connected to a hydraulic cylinder 1. A left brake is mounted on the left wheel and a right brake is mounted on the right wheel. A first cable 4 is connected to the left brake and a second cable 5 is connected to the right brake.

[0027] The braking component is typically a brake pedal. When the driver presses the brake pedal, the pedal, through a transmission assembly, pushes the hydraulic fluid in cylinder 1 to flow, which in turn moves the telescopic rod. Ultimately, this moves the integrated block 3. With the telescopic rod as its axis of symmetry, a first cable 4 and a second cable 5 are installed on either side of the telescopic rod. The movement of the integrated block 3 simultaneously moves the symmetrical first and second cables 4 and 5. The first cable 4 pulls the left brake, and the second cable 5 pulls the right brake. This allows the first and second cables 4 and 5 to simultaneously brake both the left and right wheels of the tricycle, improving safety and preventing the tricycle from veering off course during braking. This makes braking safer and eliminates the risk of drifting.

[0028] A first mounting groove 21 is formed on the main plate 2. The hydraulic cylinder 1 is embedded in the first mounting groove 21. In order to stably fix the hydraulic cylinder 1, the hydraulic cylinder 1 is usually placed in the first mounting groove 21 to fix the hydraulic cylinder 1. This can fix the hydraulic cylinder 1 and make it stable during operation.

[0029] First mounting holes are provided on both sides of the first mounting groove 21, and ear plates 11 are formed on both sides of the oil cylinder 1. Second mounting holes 111 are formed on the ear plates 11. The first bolt passes through the first mounting hole and the second mounting hole 111 and is connected to the fastener.

[0030] The first mounting slot 21 can be further fixed by the first bolt, so that the cylinder 1 and the main body plate 2 can be directly connected and fixed. This ensures that the cylinder 1 can remain stable during the movement of the tricycle and avoids the problem of brake failure.

[0031] A second mounting groove 22 is formed on the main body plate 2. The integrated block 3 is slidably mounted on the second mounting groove 22. The area of ​​the second mounting groove 22 is larger than the area of ​​the integrated block 3 so that the integrated block 3 can move within the second mounting groove 22. At the same time, the second mounting groove 22 can ensure that the integrated block 3 moves along a straight line, that is, moves along the axis of the telescopic rod. The second mounting groove 22 can show that the integrated block 3 moves along a fixed route.

[0032] The integrated block 3 is triangular in shape, and a first insertion hole 31 and a second insertion hole 32 are formed on the symmetrical sides of the integrated block 3. A first connecting post is inserted into the first insertion hole 31, and a second connecting post is inserted into the second insertion hole 32. The first connecting post is connected to the first pull wire 4, and the second connecting post is connected to the second pull wire 5.

[0033] The first and second connecting posts are typically made of lead blocks and are directly fused together with the first pull wire 4 and the second pull wire 5. This increases the integration of the first pull wire 4 and the first connecting post, as well as the integration of the second pull wire 5 and the second connecting post. It also increases the connection strength between the first pull wire 4, the second pull wire 5 and the first connecting post and the second connecting post, thus preventing breakage.

[0034] A first notch 34 and a second notch 35 are formed on the edges of the two symmetrical sides of the integrated block 3. The first notch 34 is connected to the first insertion hole 31, and the second notch 35 is connected to the second insertion hole 32. The first pull wire 4 moves within the first notch 34, and the second pull wire 5 moves within the second notch 35. During the movement of the integrated block 3, the clamping between the first pull wire 4 and the second pull wire 5 will change. In order to ensure the movement space of the first pull wire 4 and the second pull wire 5, a first notch 34 and a second notch 35 are provided on the edge of the integrated block 3, so that the first pull wire 4 can swing in the first notch 34 and the second pull wire 5 can swing in the second notch 35. In addition, a winding port is provided on the first and second insertion holes 32. During the installation of the first connecting post, the first pull wire 4 will pass through the winding port and be placed in the first notch 34. Similarly, during the installation of the second connecting post, the second pull wire 5 will pass through the winding port and be placed in the second notch 35. This makes it easier for the staff to install, reduces the installation difficulty, and allows the first pull wire 4 and the second pull wire 5 to stretch more freely in the integrated block 3 without folding or bending. This allows the first pull wire 4 and the second pull wire 5 to move synchronously and reduces the phenomenon of brake deviation.

[0035] To prevent dust from entering and affecting the movement of integrated circuit 3, a mounting cover 6 is installed on the junction box. The mounting cover 6 can prevent external dust from entering.

[0036] Example 2

[0037] like Figure 1As shown, if the tricycle has a handbrake, the handbrake can be connected via a third cable. The third cable moves the integrated block 3, which in turn moves the first cable 4 and the second cable 5, thus simultaneously braking the left and right wheels.

[0038] To allow the third pull wire to swing freely, a third insertion hole 33 and a third notch 36 are provided on the integrated block 3. The third notch 36 is located in the middle of the third insertion hole 33. A third connecting post is inserted into the third insertion hole 33, and a third pull wire is installed inside the third connecting post. The third pull wire swings within the third notch 36 and passes through the third insertion hole 33 and the third notch 36. Similarly, the third pull wire and the third connecting post are integrally formed, which can make the connection strength between the third pull wire and the third connecting post higher.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
