Description

Technical Field

[0001] The utility model relates to the technical field of speed reducers for battery replacement in electric trucks, in particular to a lifting speed reducer for battery replacement in electric trucks. Background Art

[0002] During the operation of electric trucks, in order to ensure safety and improve transportation efficiency, it is often necessary to perform battery replacement operations. During the battery replacement process, the lifting reducer plays a vital role. The lifting reducer is a device specially used for battery replacement in electric trucks. When used in conjunction with a crane, it can achieve rapid lifting and lowering of electric trucks, making the battery replacement process more convenient and safe. Through the lifting reducer, electric trucks can complete the battery replacement task in a short time, greatly saving battery replacement time and improving transportation efficiency. At the same time, the lifting reducer can also play a deceleration role, ensuring safety during the battery replacement process and preventing accidents caused by excessive speed.

[0003] The lifting reducer used in the battery replacement process of electric trucks must provide sufficient torque to complete the work when performing the task of lifting heavy objects. However, since the torque transmission process will cause the equipment to heat up, poor heat dissipation will cause the reducer to overheat and cause problems. Overheating may damage the internal components of the reducer, reducing its performance and life, and thus affecting the normal operation and use of the entire electric truck. Therefore, when designing the lifting reducer, in addition to considering its ability to provide sufficient torque, it is also necessary to take into account the heat dissipation problem to ensure that the reducer maintains an appropriate temperature range during operation to maintain its performance and extend its service life.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] In the utility model, a transmission mechanism and a guide mechanism are provided. The transmission mechanism is driven by a motor and utilizes the efficient cooperation of a transmission gear and a driving gear to achieve the effect of rapid transmission of torque. The size of the transmission gear is much larger than the size of the driving gear, so that the torque can quickly drive the heat dissipation fan to rotate through the transmission force of the motor, thereby solving the problem of heat generation during torque transmission. The rapid rotation of the transmission mechanism drives the first heat dissipation fan and the second heat dissipation fan to rotate at high speed, generating a high-speed airflow, and achieving a rapid guide effect through the first guide air slot and the second guide air slot. Since the high-speed airflow runs through the air slots on the left and right sides of the reducer body, the heat dissipation airflow of the reducer body is more comprehensively in contact with the reducer body, thereby improving the overall heat dissipation effect. The air slots opened by the guide mechanism on the reducer body increase the heat dissipation contact area, so that the heat of the reducer body can be more effectively dissipated. Through the guide mechanism, the heat of the reducer body is evenly dispersed in all directions, thereby reducing temperature fluctuations and improving the stability of the reducer.

The second transmission rotating rod 314 is installed at the right end of the reducer body 2, and the second transmission gear 308 is fixedly installed on the second transmission rotating rod 314. A second driving gear 309 is arranged behind the second transmission gear 308, and the second driving gear 309 and the second transmission gear 308 are meshed with each other. A second rotating rod 310 is fixedly installed in the middle part of the second driving gear 309, and a second bearing seat 311 is installed at the right end of the second rotating rod 310. The upper and lower ends of the second bearing seat 311 are fixedly installed with second support rods 312, and the second support rod 312 is fixedly installed on the outer wall of the reducer body 2. The left end of the second rotating rod 310 is fixedly installed with a second cooling fan 313;

[0023] The first transmission gear 301 and the first driving gear 302 in the transmission mechanism 3 are meshed with each other, and the high efficiency of the transmission gear is used to realize the rapid transmission of torque. Since the size of the transmission gear is much larger than the driving gear, the transmission of torque is more efficient; the drive of the motor 1 causes the first transmission rotating rod 307 to rotate, driving the first cooling fan 306 to rotate at high speed, and the generated airflow passes through the wind slot, effectively taking away the heat, thereby reducing the temperature inside the reducer; similarly, the second transmission rotating rod 314 on the right side of the reducer body 2 will also drive the second transmission gear 308 to rotate, and the second transmission gear 308 and the second driving gear 309 are meshed with each other, and the high efficiency of the transmission gear is used to realize the rapid transmission of torque, thereby driving the second cooling fan 313 to rotate at high speed, and the generated airflow passes through the wind slot, effectively taking away the heat;

[0024] The guide mechanism 4 includes a first guide air groove 401 and a second guide air groove 402. The first guide air groove 401 and the second guide air groove 402 are opened at both ends of the reducer body 2. Multiple groups of first guide air grooves 401 and second guide air grooves 402 are distributed on the outer wall of the reducer body 2; the air grooves opened by the guide mechanism 4 on the reducer body 2 increase the heat dissipation contact area, so that the heat of the reducer body 2 can be dissipated more effectively. Through the guide mechanism 4, the heat of the reducer body 2 is evenly dispersed in all directions, reducing temperature fluctuations and improving the stability of the reducer.

[0025] The working principle of the utility model is as follows: the lifting reducer for battery replacement of electric trucks is additionally provided with a transmission mechanism 3 and a diversion mechanism 4. Before using the lifting reducer for battery replacement of electric trucks, the transmission mechanism 3 needs to be pre-installed on the motor 1 and the reducer body 2, and an air groove is provided on the outer wall of the reducer body 2. When using the lifting reducer for battery replacement of electric trucks, starting the motor 1 can drive the transmission mechanism 3 to start, thereby achieving the diversion and heat dissipation effect. Specifically, the motor 1 drives the first transmission rotating rod 307 to rotate, and the first transmission rotating rod 307 drives the first transmission gear 301 to rotate. The first transmission gear 301 is meshed with the first drive gear 302 to drive the first rotating rod 303 and the first cooling fan 306 to rotate. The larger first transmission gear 301 can drive the smaller first drive gear 302 to rotate at high speed, thereby achieving the effect of high-speed diversion. At the same time, the reducer body 2 will also drive the second transmission rotating rod 314 on the right side to rotate, and the second transmission rotating rod 314 drives the second transmission gear 308 to rotate. The second transmission gear 308 and the second transmission gear 308 mesh with each other, driving the second rotating rod 310 and the second cooling fan 313 to rotate at a high speed, thereby achieving the effect of high-speed diversion; the first cooling fan 306 blows air to the right, so that the high-speed airflow penetrates the first guide air slot 401 and the second guide air slot 402 on the left side of the reducer body 2, thereby achieving the effect of rapid heat dissipation. Similarly, the second cooling fan 313 blows air to the left, so that the high-speed airflow penetrates the first guide air slot 401 and the second guide air slot 402 on the right side of the reducer body 2, thereby achieving the effect of rapid heat dissipation; in summary, the transmission mechanism 3 uses the transmission force of the motor 1 to cooperate with the transmission gear and the driving gear. The size of the transmission gear is much larger than the size of the driving gear, thereby achieving the effect of quickly driving the cooling fan to rotate with the transmission force of the motor 1, and achieving the effect of high-speed diversion and efficient heat dissipation without increasing energy consumption; and the diversion mechanism 4 opens an air slot on the reducer body 2 to increase the heat dissipation contact area, thereby making the heat dissipation airflow of the transmission mechanism 3 more comprehensively contact with the reducer body 2, thereby achieving the effect of efficient heat dissipation.
