Description

Technical Field

[0001] This utility model relates to the technical field of electric tricycle accessories, and more specifically, to a power box for an electric tricycle motorcycle. Background Technology

[0002] The power housing of electric tricycles, as the core power transmission unit, generally adopts a gear transmission system integrated with the motor design. To ensure the long-term stable operation of the transmission components, lubricating oil needs to be added periodically through the oil filler to maintain lubrication. In conventional settings, this is usually achieved by installing a fixed oil filling pipe on the top of the housing to directly introduce lubricating oil into the gearbox cavity. However, traditional oil filler ports have a fixed, immovable structure, which means that during the oil filling process, lubricating oil can only flow into the gearbox along a fixed path, failing to cover the side walls and corner areas of the gear set. This design flaw creates a continuous lubrication blind spot within the powerbox, causing abnormal localized wear on the gears and significantly shortening the service life of the transmission system.

[0003] In view of this, we propose a power box for an electric tricycle. Utility Model Content

[0004] Technical problems to be solved The purpose of this utility model is to provide a power box for an electric tricycle to solve the problem of blind spots in the oil filling when adding lubricating oil through a fixed oil inlet as mentioned in the background art.

[0005] An electric tricycle power box body includes a power box body. The top of the power box body has an oil inlet. An oil inlet pipe is rotatably connected to the oil inlet. Multiple connecting rods are fixedly connected to the bottom of the oil inlet pipe. A rotating rod is fixedly connected to the bottom of the multiple connecting rods. An oil tank is fixedly connected inside the power box body. A partition plate is fixedly connected inside the oil tank, dividing the oil tank into an oil filling chamber and a power chamber. An oil suction pump is fixedly connected inside the oil filling chamber. An oil delivery pipe is connected to the oil suction pump. The oil delivery pipe passes through the partition plate and its other end is connected to an oil guide block. An oil outlet for oil filling is provided at the bottom of the oil guide block. The oil guide block is slidably connected inside the oil filling chamber. A drive assembly is provided at the bottom of the rotating rod. A drive assembly is used to drive the oil guide block to move in order to expand the oil injection range of the oil outlet and reduce the oil injection blind zone.

[0006] Preferably, the rotating rod passes through the partition plate, and sealing rings are fixedly connected to the joints of the rotating rod and the oil pipe with the partition plate.

[0007] Preferably, a turntable is fixedly connected to the bottom of the oil injection pipe, and a rotating ring with a T-shaped cross-section is fixedly connected to the oil injection pipe. A rotating groove adapted to the size of the rotating ring is opened in the oil injection port.

[0008] Preferably, the drive assembly includes a first bevel gear rotatably connected to the rotating rod, a screw rotatably connected to the oil filling chamber, and a second bevel gear fixedly connected to the screw and meshing with the first bevel gear. A threaded sleeve is threadedly connected to the screw via a ball screw pair, and the threaded sleeve is fixedly connected to the oil guide block.

[0009] Preferably, a slider with a T-shaped cross-section is fixedly connected to the oil guide block, and a groove adapted to the size of the slider is formed on the inner wall of the power chamber.

[0010] Preferably, a channel for lubricating oil to pass through is provided between the connecting rods.

[0011] Preferably, the length of the portion of the oil pipeline located inside the power compartment is greater than the length of the chute, so that it can move from one end of the chute to the other end in conjunction with the oil guide block.

[0012] Compared with existing technologies, the advantages of this utility model are: This invention solves the problem of large lubrication blind spots in the traditional fixed oil injection mode by actively displacing the oil guide block, so as to dynamically cover the edge and side wall area of ​​the gear assembly in the power compartment with lubricating oil, and ensures uniform oil film coverage throughout the gear system.

[0013] The mechanical linkage design of the rotary drive of the oil injection pipe and the linear motion of the oil guide block in this utility model forms a closed power transmission chain, which can complete the refueling operation simultaneously without the need for external energy. This improves convenience and reduces the input of power resources. The operator only needs to rotate the oil injection pipe to control the trajectory of the oil guide block, simplifying the multi-step adjustment in the traditional refueling operation into a single action. This significantly reduces the complexity of maintenance and improves the fault tolerance of operation, and is especially suitable for the working environment where the chassis space of a three-wheeled motorcycle is limited.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within 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.

[0019] Please see Figure 1-6 This utility model provides a technical solution: An electric tricycle power box body includes a power box body 1. The top of the power box body 1 has an oil inlet 11. An oil inlet pipe 15 is rotatably connected to the oil inlet 11. Multiple connecting rods 16 are fixedly connected to the bottom of the oil inlet pipe 15. A rotating rod 17 is fixedly connected to the bottom of the multiple connecting rods 16. An oil tank 18 is fixedly connected inside the power box body 1. A partition plate 19 is fixedly connected inside the oil tank 18, dividing the oil tank 18 into an oil filling chamber 191 and a power chamber 192. An oil suction pump 110 is fixedly connected inside the oil filling chamber 191. An oil delivery pipe 111 is connected to the oil suction pump 110. The oil delivery pipe 111 passes through the partition plate 19, and its other end is connected to an oil guide block 1. 12. The bottom of the oil guide block 112 is provided with an oil outlet 113 for oil injection. The oil guide block 112 is slidably connected in the oil injection chamber 191. The bottom of the rotating rod 17 is provided with a drive assembly 2. The drive assembly 2 is used to drive the oil guide block 112 to move to expand the oil injection range of the oil outlet 113 and reduce the oil injection blind zone. With this configuration, the design of multiple connecting rods 16 fixed to the bottom of the oil injection pipe 15 and extending to the rotating rod 17 allows power to be transmitted from the top of the box to the inside, realizing the direct linkage between the external rotation oil injection operation and the internal oil guide mechanism movement. The lubrication trajectory control function can be activated synchronously without the need for an additional drive device. At the same time, the setting of multiple connecting rods 16 can also enhance the transmission stability.

[0020] It should be noted that the top of the oil filling pipe 15 should be equipped with an oil tank 18 cover to seal the oil tank 18 after the lubricating oil is added. In addition, the oil supply pipe 111 should be made of hard material at the connection point with the sealing ring 114 to ensure the sealing of the connection part, while the part of the oil supply pipe 111 located in the power compartment 192 should be made of soft material to facilitate its movement with the oil guide block 112.

[0021] Specifically, the overlapping section of the oil supply pipe 111 and the sealing ring 114 can be set as a 304 stainless steel rigid pipe section, which can form a precise compression fit with the sealing ring 114 to prevent leakage. The movable section of the oil supply pipe 111 extending to the power compartment 192 can be replaced with a fluororubber hose, which can adaptively bend and deform during the movement of the oil guide block 112, while keeping the oil passage unobstructed.

[0022] The rotating rod 17 passes through the partition plate 19, and the joints of the rotating rod 17 and the oil supply pipe 111 with the partition plate 19 are all fixedly connected with sealing rings 114. This arrangement can effectively block the leakage and contamination of lubricating oil into the motor gear area and prevent oil and gas from back seeping from the power compartment 192 into the oil filling compartment 191.

[0023] In addition, a turntable 12 is fixedly connected to the bottom of the oil injection pipe 15, and a rotating ring 13 with a T-shaped cross section is fixedly connected to the oil injection pipe 15. A rotating groove 14 with a size matching the rotating ring 13 is opened in the oil injection port 11. This arrangement can achieve dynamic stability during the rotation of the oil injection pipe 15 and ensure that the transmission rod system always transmits accurately in the vertical direction.

[0024] Secondly, the drive assembly 2 includes a first bevel gear 21 rotatably connected to the rotating rod 17, a screw 23 rotatably connected to the oil filling chamber 191, and a second bevel gear 22 fixedly connected to the screw 23 and meshing with the first bevel gear 21. A screw sleeve 24 is threadedly connected to the screw 23 through a ball screw pair. The screw sleeve 24 is fixedly connected to the oil guide block 112. This configuration can convert the rotational motion of the rotating rod 17 into the linear motion of the oil guide block 112.

[0025] Furthermore, a slider 25 with a T-shaped cross-section is fixedly connected to the oil guide block 112, and a groove 26 adapted to the size of the slider 25 is provided on the inner wall of the power chamber 192. This arrangement can prevent the oil guide block 112 from deflecting due to oil pressure impact and prevent the oil guide block 112 from shifting.

[0026] Specifically, a channel for lubricating oil is provided between the connecting rods 16. In addition to transmitting the rotation of the turntable 12 to the rotating rod 17, the connecting rods 16 can also ensure that the lubricating oil can enter the oil filling chamber 191 of the oil tank 18 from the channel. Furthermore, the connecting rods 16 can also intercept large foreign objects to prevent them from entering the oil tank 18 and affecting the operation of the oil suction pump 110.

[0027] Furthermore, the length of the portion of the oil pipe 111 located within the power compartment 192 is greater than the length of the chute 26, allowing it to move from one end of the chute 26 to the other in conjunction with the oil guide block 112. This arrangement ensures that the length of the oil pipe 111 is sufficient to allow the oil guide block 112 to move.

[0028] Working principle: When the power box of the electric tricycle needs to be filled with lubricating oil, the operator unscrews the oil tank 18 cap at the top of the oil filling pipe 15 to inject lubricating oil. The lubricating oil enters the oil filling chamber 191 in the oil tank 18 through the channel of the connecting rod 16. Then, the turntable 12 is rotated to drive the rotating rod 17 to rotate. The rotation of the rotating rod 17 drives the first bevel gear 21 at its bottom to mesh with the second bevel gear 22, which drives the screw 23 to rotate. The ball screw pair on the screw 23 converts the rotational motion into the linear displacement of the screw sleeve 24, which pushes the oil guide block 112 to move directionally along the T-shaped slide groove 26 on the inner wall of the power chamber 192. During this process, the oil suction pump 110 continuously sucks out the lubricating oil in the oil filling chamber 191, and delivers the lubricating oil to the oil guide block 112 through the oil delivery pipe 111 and discharges it through the oil outlet 113.
