Description

Technical Field

[0001] The invention belongs to the technical field of passenger tricycles, and in particular relates to a motor controller for a passenger tricycle with high precision and high performance. Background Art

[0002] A tricycle is a means of transport modified from a bicycle, which can carry people or goods. It is divided into human-powered tricycles, electric passenger tricycles and children's tricycles, etc. Among them, electric passenger tricycles are popular among people because they use high-quality large-capacity traction lead-acid batteries, which are powerful; they use high-quality DC motors, which have low operating noise and long service life; they use a stepless speed regulation system, simple structure and easy operation.

[0003] The core technology of electric passenger tricycles is the "three electrics", namely the power battery, motor controller and motor. Among them, the motor controller is the most important of the three electrics. It converts the electric energy stored in the power battery into the electric energy required to drive the motor according to instructions such as gear position, throttle, brake, etc., to control the starting operation, forward and backward speed, climbing intensity and other driving conditions of the electric vehicle, or help the electric vehicle brake and store part of the braking energy in the power battery, thereby realizing high-precision and high-performance control of the electric passenger tricycle to meet the user's usage needs.

[0004] The existing motor controller for electric passenger tricycles will generate a large amount of heat when in use. Since the motor controller lacks the necessary heat dissipation mechanism, the heat is not easy to dissipate and will accumulate around the motor controller, causing the motor controller to work in a high-heat environment, greatly increasing the chance of damage to the motor controller and shortening the service life of the motor controller. It is also easy to cause the motor controller to spontaneously combust, posing a major safety hazard.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a high-precision and high-performance motor controller for a passenger three-wheeled vehicle. Summary of the invention

[0006] The purpose of the present invention is to provide a high-precision and high-performance motor controller for a passenger tricycle, so as to solve the problem that the above-mentioned motor controller is prone to damage or spontaneous combustion due to the lack of a heat dissipation mechanism.

[0007] In order to achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows:

[0008] A high-precision and high-performance motor controller for a passenger tricycle comprises a motor controller body, a cooling mechanism, and an auxiliary cooling pipe.

[0009] The cooling mechanism is arranged on the lower side of the motor controller body, and is used to accommodate the motor controller body, and then to cool the motor controller body. The cooling mechanism includes a base structure, and a pair of inner side walls of the base structure are fixedly connected to limit strips, and the motor controller body is arranged on the limit strips. A plurality of heat dissipation holes are opened on the lower bottom of the base structure, and a first accommodating box and a second accommodating box are respectively fixedly connected to a pair of outer side walls of the base structure, and an air curtain type heat dissipation component is arranged in the base structure.

[0010] The auxiliary cooling pipe is installed on the second housing box and is used to assist in cooling the motor controller body. The auxiliary cooling pipe is connected to a plurality of inclined and evenly distributed connecting pipes. The auxiliary cooling pipe is connected to a second nozzle, and one end of the second nozzle passes through the base structure and is inserted into the second housing box.

[0011] Furthermore, a filter is provided at the lower bottom of the base structure, and the filter is arranged corresponding to the heat dissipation holes to block external dust and prevent external dust from entering the base structure through the heat dissipation holes, thereby ensuring that the base structure is clean and tidy.

[0012] Furthermore, a temperature sensor is provided in the base structure, and the temperature sensor is used to monitor the temperature in the base structure.

[0013] A control box is installed on the outer wall of the base structure, and a processor is arranged in the control box. The temperature sensor is electrically connected to the processor. The temperature sensor sends the monitored temperature signal to the processor, which is then used to control the operation of the cooling mechanism and the auxiliary cooling pipe to cool the motor controller body.

[0014] Furthermore, a partition is provided in the first containing box to separate and form a filling cavity and an installation cavity.

[0015] The partition is made of heat-dissipating metal material, and the heat generated by the high-pressure air pump when it is working can be transferred to the partition. Since the filling cavity is filled with cooling liquid, the cooling liquid can cool the high-pressure air pump through the partition, avoiding the high temperature of the high-pressure air pump and ensuring the safety of the use of the high-pressure air pump.

[0016] A filling cavity and an installation cavity are formed between the partition and the inner wall of the first storage box. The filling cavity and the second storage box are both filled with cooling liquid. The installation cavity is used to install a high-pressure air pump.

[0017] Furthermore, the air curtain type heat dissipation assembly includes a high-pressure air pump for generating a high-pressure airflow, and the high-pressure air pump is arranged in the installation cavity.

[0018] The high-pressure air pump is electrically connected to the processor, so that the operation of the high-pressure air pump can be controlled by the processor.

[0019] The high-pressure air pump is connected to an air delivery pipe for delivering high-pressure airflow. One end of the air delivery pipe away from the high-pressure air pump is connected to a first U-shaped pipe for branching the high-pressure airflow to form different air curtains.

[0020] Furthermore, both air outlet ends of the first U-shaped tube are communicated with the interior of the base structure, and both air outlet ends of the first U-shaped tube are connected to a first transverse tube, on which a plurality of evenly distributed first nozzles are installed. The high-pressure airflow in the first U-shaped tube can form an air curtain under the action of the first transverse tube and the first nozzle, and the air curtain is used to blow away the heat generated by the motor controller body during operation, thereby playing a role in cooling the motor controller body.

[0021] Furthermore, solenoid valves are installed on both air outlet ends of the first U-shaped tube, and the solenoid valves are electrically connected to the processor. The solenoid valves can be used to control the size of the air outlet of the first U-shaped tube, and then the flow rate of the air curtain can be controlled to change the heat dissipation effect of the air curtain.

[0022] Furthermore, a pair of second transverse tubes are provided in the base structure, and an air collection groove is drilled on a surface of the second transverse tube close to the first transverse tube. The air collection groove is arranged corresponding to the first nozzle. The gas blown by the first transverse tube and the first nozzle enters the second transverse tube through the air collection groove, thereby avoiding the formation of gas turbulence and ensuring the air curtain's effect of blowing away the heat of the motor controller body.

[0023] A second U-shaped tube is connected between the pair of the second transverse tubes and is used to gather the gas in the second transverse tubes.

[0024] Furthermore, an exhaust pipe is connected to the second U-shaped tube, and one end of the exhaust pipe away from the second U-shaped tube is inserted into the cooling liquid in the second containing box, so that the gas with heat can enter the cooling liquid in the second containing box for cooling, so as to reuse the high-pressure gas.

[0025] A pair of one-way valves are installed on the second U-shaped tube. The one-way valves are arranged corresponding to the second transverse tube to control the on-off status of the second U-shaped tube branch and also enable the high-pressure gas to be discharged smoothly to avoid turbulence.

[0026] Furthermore, a pair of connecting columns are connected between the auxiliary cooling pipe and the base structure, which are used to fix the auxiliary cooling pipe to ensure the firmness of the auxiliary cooling pipe when in use.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] The present invention facilitates cooling of the motor controller by setting up corresponding mechanisms, avoids heat accumulation generated when the motor controller is running, ensures the working environment of the motor controller, greatly reduces the probability of damage to the motor controller due to high temperature, and thus ensures the service life of the motor controller. At the same time, it can also greatly reduce the probability of spontaneous combustion of the motor controller, greatly reducing safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The present invention will be described in detail below in conjunction with the various embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0038] The present invention discloses a high-precision and high-performance motor controller for a passenger tricycle, referring to Figure 1-Figure 6 As shown, it includes a motor controller body 1, a cooling mechanism 2, an auxiliary cooling pipe 3, and a liquid pump 4.

[0039] The cooling mechanism 2 is disposed at the lower side of the motor controller body 1 for accommodating the motor controller body 1 and further for cooling the motor controller body 1 . The cooling mechanism 2 includes a base structure 201 for installing the motor controller body 1 .

[0040] In addition, a pair of inner walls of the base structure 201 are fixedly connected to a limit strip 202, and the motor controller body 1 is arranged on the limit strip 202. The limit strip 202 is used to support the motor controller body 1, so that there is a certain distance between the motor controller body 1 and the bottom wall of the base structure 201, thereby facilitating the operation of the air curtain type heat dissipation assembly.

[0041] Specifically, a plurality of heat dissipation holes 203 are drilled at the bottom of the base structure 201 for heat exchange and cooling. That is, when the air curtain heat dissipation assembly is not in operation, the heat generated by the motor controller body 1 during operation will be discharged through the heat dissipation holes 203 .

[0042] In addition, a filter 204 is provided at the bottom of the base structure 201. The filter 204 is arranged corresponding to the heat dissipation hole 203 to block external dust and prevent external dust from entering the base structure 201 through the heat dissipation hole 203, thereby ensuring that the base structure 201 is clean and tidy.

[0043] refer to Figure 1-Figure 5 As shown, a first receiving box 205 and a second receiving box 206 are fixedly connected to a pair of outer walls of the base structure 201 , respectively. The first receiving box 205 is used to install the air curtain type heat dissipation component and the cooling liquid 211 , and the second receiving box 206 is used to contain the cooling liquid 211 .

[0044] A reflux pipe 207 is connected between the first container box 205 and the second container box 206 . Specifically, both ends of the reflux pipe 207 are respectively connected to the filling cavity 209 and the interior of the second container box 206 , so as to circulate the cooling liquid 211 and avoid waste of the cooling liquid 211 .

[0045] In addition, a partition 208 is provided in the first receiving box 205 to separate and form a filling cavity 209 and an installation cavity 210 .

[0046] Preferably, the partition 208 is made of heat-dissipating metal material, and the heat generated by the high-pressure air pump 213 during operation can be transferred to the partition 208. Since the filling cavity 209 is filled with cooling liquid 211, the cooling liquid 211 can cool the high-pressure air pump 213 through the partition 208, thereby preventing the high-pressure air pump 213 from being overheated and ensuring the safety of the use of the high-pressure air pump 213.

[0047] Specifically, a filling cavity 209 and an installation cavity 210 are formed between the partition 208 and the inner wall of the first receiving box 205 . The filling cavity 209 and the second receiving box 206 are both filled with cooling liquid 211 . The installation cavity 210 is used to install a high-pressure air pump 213 .

[0048] In addition, a mounting plate 212 is provided in the mounting cavity 210 for placing the liquid extraction pump 4 so that the cooling liquid 211 can be extracted by the liquid extraction pump 4 to realize the recycling of the cooling liquid 211 .

[0049] refer to Figure 2-Figure 5 As shown, an air curtain type heat dissipation component is provided in the base structure 201. When the motor controller body 1 generates high heat during operation, the air curtain type heat dissipation component is operated to cool the motor controller body 1 to prevent the motor controller body 1 from being damaged due to high temperature.

[0050] Among them, the air curtain type heat dissipation component includes a high-pressure air pump 213 for generating high-pressure airflow. The high-pressure air pump 213 is arranged in the installation cavity 210. The high-pressure air pump 213 is electrically connected to the processor to facilitate controlling the operation of the high-pressure air pump 213 through the processor.

[0051] In addition, the high-pressure air pump 213 is connected to an air delivery pipe 214 for delivering high-pressure airflow, and one end of the air delivery pipe 214 away from the high-pressure air pump 213 is connected to a first U-shaped pipe 215, that is, Figure 4 The shape shown is used to branch the high-pressure airflow to form different air curtains.

[0052] Specifically, both air outlet ends of the first U-shaped tube 215 are connected to the interior of the base structure 201, and both air outlet ends of the first U-shaped tube 215 are connected to the first transverse tube 216, and a plurality of evenly distributed first nozzles 217 are installed on the first transverse tube 216. The high-pressure airflow in the first U-shaped tube 215 can form an air curtain under the action of the first transverse tube 216 and the first nozzle 217. The air curtain is used to blow away the heat generated by the motor controller body 1 during operation, thereby playing a role in cooling the motor controller body 1. In addition, the air curtain can also play a role in dust isolation, again preventing external dust from adhering to the bottom of the motor controller body 1, thereby ensuring the safety of the motor controller body 1.

[0053] In addition, solenoid valves 218 are installed on both air outlet ends of the first U-shaped tube 215. The solenoid valves 218 are electrically connected to the processor. The solenoid valves 218 can be used to control the size of the air outlet of the first U-shaped tube 215, and then the number of air curtain layers and the flow rate between different air curtains can be controlled to ensure the heat dissipation effect of the air curtain and maximize the operating safety of the motor controller body 1.

[0054] refer to Figure 1-Figure 5 As shown, a pair of second transverse tubes 219 are provided in the base structure 201, and an air collecting groove 220 is cut on one surface of the second transverse tube 219 close to the first transverse tube 216. The air collecting groove 220 is arranged corresponding to the first nozzle 217. The gas blown by the first transverse tube 216 and the first nozzle 217 enters the second transverse tube 219 through the air collecting groove 220 to avoid the formation of turbulent flow of gas, thereby ensuring the effect of the air curtain on blowing away the heat of the motor controller body 1. The relationship between the second transverse tube 219 and the air collecting groove 220 is shown in FIG. Figure 5 shown.

[0055] A second U-shaped tube 221 is connected between the pair of second transverse tubes 219 to collect the gas in the second transverse tubes 219. The shape of the second U-shaped tube 221 is as shown in FIG. Figure 5 shown.

[0056] In addition, an exhaust pipe 222 is connected to the second U-shaped tube 221, and one end of the exhaust pipe 222 away from the second U-shaped tube 221 is inserted into the cooling liquid 211 in the second containing box 206, so that the gas with heat can enter the cooling liquid 211 in the second containing box 206 for cooling, so as to reuse the high-pressure gas and improve the overall recycling effect.

[0057] Preferably, a pair of one-way valves are installed on the second U-shaped tube 221, and the one-way valves are arranged corresponding to the second transverse tube 219 to control the on-off status of the branch tubes of the second U-shaped tube 221, and also to enable the high-pressure gas to be discharged smoothly to avoid the formation of turbulence.

[0058] Specifically, a temperature sensor is disposed in the base structure 201 , and the temperature sensor is used to monitor the temperature in the base structure 201 .

[0059] In addition, a control box is installed on the outer wall of the base structure 201, and a processor is installed in the control box. The temperature sensor is electrically connected to the processor. The temperature sensor sends the monitored temperature signal to the processor, which is then used to control the operation of the cooling mechanism 2 and the auxiliary cooling pipe 3 to cool the motor controller body 1.

[0060] refer to Figure 1-Figure 5 As shown, the auxiliary cooling pipe 3 is installed on the second containing box 206, and is used for auxiliary cooling of the motor controller body 1. A plurality of second nozzles 301 that are evenly distributed and inclined are connected to the auxiliary cooling pipe 3. The high-pressure airflow that enters the second containing box 206 through the exhaust pipe 222 enters the auxiliary cooling pipe 3 through the connecting pipe 303, and is then discharged through the plurality of second nozzles 301 on the auxiliary cooling pipe 3. The surface of the motor controller body 1 can be cooled again, thereby greatly improving the overall cooling effect of the motor controller body 1.

[0061] Preferably, the inclination angle of the second nozzle 301 is 20°, ensuring that the airflow sprayed by the second nozzle 301 can be sprayed onto the surface of the motor controller body 1, greatly improving the cooling effect on the motor controller body 1 and avoiding damage to the motor controller body 1 due to high temperature.

[0062] A pair of connecting columns 302 are connected between the auxiliary cooling pipe 3 and the base structure 201 to fix the auxiliary cooling pipe 3 and ensure the firmness of the auxiliary cooling pipe 3 when in use.

[0063] In addition, the auxiliary cooling pipe 3 is connected to a connecting pipe 303, one end of the connecting pipe 303 passes through the base structure 201 and is inserted into the second containing box 206, so that the airflow that has been cooled in the second containing box 206 can enter the auxiliary cooling pipe 3 through the connecting pipe 303, and is sprayed out under the action of multiple second nozzles 301 on the auxiliary cooling pipe 3, so as to cool down the surface of the motor controller body 1 again, thereby ensuring the cooling effect of the motor controller body 1.

[0064] refer to Figure 1-Figure 6 As shown, a liquid pump 4 is provided on the mounting plate 212, and the liquid pump 4 is used to extract the cooling liquid 211 in the filling cavity 209. The liquid pump 4 is connected to a liquid suction pipe 401 and a liquid discharge pipe 402. One end of the liquid suction pipe 401 passes through the partition 208 and is inserted into the cooling liquid 211 in the first receiving box 205. One end of the liquid discharge pipe 402 passes through the base structure 201 and is inserted in the base structure 201. One end of the liquid discharge pipe 402 located in the base structure 201 is connected to a liquid dispensing pipe 403, and a plurality of evenly distributed third nozzles 404 are connected to the liquid dispensing pipe 403. The position of the third nozzle 404 is referenced Figure 4As shown, the liquid pump 4 extracts the cooling liquid 211 in the filling chamber 209 through the liquid extraction pipe 401, discharges the extracted cooling liquid 211 through the discharge pipe 402, the liquid distribution pipe 403 and the third nozzle 404, and makes the air curtain moist, so as to further improve the cooling effect of the air curtain on the motor controller body 1 and avoid high temperature of the motor controller body 1.

[0065] When in use, the motor controller body 1 is placed in the base structure 201 and supported by the limit strips 202 , so that there is a certain distance between the motor controller body 1 and the bottom wall of the base structure 201 .

[0066] Among them, the temperature sensor in the base structure 201 is used to monitor the temperature in the base structure 201, that is, the working environment temperature of the motor controller body 1. When the temperature sensor detects that the temperature in the base structure 201 is low, the high-pressure air pump 213 and the liquid pump 4 do not run. At this time, the heat in the base structure 201 is discharged through the heat dissipation holes 203 to save energy.

[0067] When the temperature sensor detects that the temperature inside the base structure 201 is high, the temperature sensor sends a monitoring signal to the processor, and the processor controls the operation of the high-pressure air pump 213. The high-pressure air pump 213 generates a high-pressure airflow, and the high-pressure airflow is sprayed toward the second transverse pipe 219 through the air pipe 214, the first U-shaped pipe 215, the first transverse pipe 216 and the first nozzle 217, thereby forming an air curtain. The fluidity of the air curtain is used to take away the heat inside the base structure 201, thereby achieving a cooling effect.

[0068] In addition, the staff can control the number of layers and flow rate of the air curtain through the processor. That is, when the heat in the base structure 201 is too large, the base structure 201 needs to be rapidly cooled. The processor controls the solenoid valve 218 on one of the first U-shaped tubes 215 to close, and the high-pressure airflow can be discharged through an outlet pipe of the first U-shaped tube 215 to form a single-layer rapid air curtain. The single-layer rapid air curtain can quickly take away the heat in the base structure 201, thereby achieving the purpose of rapid heat dissipation.

[0069] When there is no need to quickly dissipate heat for the base structure 201, the processor can open the two solenoid valves 218 at the same time, and the high-pressure airflow is discharged through the two air outlet pipes of the first U-shaped tube 215 to form a double-layer air curtain. The double-layer air curtain can not only take away the heat in the base structure 201, but also prevent external dust from entering the base structure 201, thereby ensuring the safety of the base structure 201. In addition, since the two air outlet pipes of the first U-shaped tube 215 discharge air at the same time, the flow rate of the air curtain is slowed down, thereby increasing the radiation range of the air curtain to the heat in the base structure 201, thereby ensuring the heat dissipation effect of the air curtain on the motor controller body 1.

[0070] In addition, when the single-layer rapid air curtain still cannot achieve the purpose of rapid cooling, the processor turns on the liquid pump 4, and the liquid pump 4 draws the cooling liquid 211 in the filling chamber 209 through the liquid pumping tube 401, and discharges it through the discharge pipe 402, the liquid distributor 403 and the third nozzle 404, and sprays the discharged cooling liquid 211 onto the air curtain, so that the air curtain is moistened. The moistened air curtain can achieve the cooling effect again, avoiding the height of the motor controller body 1. At the same time, since the liquid distributor 403 and the third nozzle 404 are arranged between a pair of first transverse tubes 216, the cooling liquid 211 sprayed by the liquid distributor 403 and the third nozzle 404 is blocked by the air curtain and will not be sprayed onto the motor controller body 1, thereby ensuring the safety of the motor controller body 1.

[0071] The air curtain finally passes through the air collecting groove 220 on the second transverse tube 219 into the second U-shaped tube 221 and the exhaust pipe 222, and then enters the cooling liquid 211 in the second containing box 206. After being cooled again by the cooling liquid 211, it flows to the auxiliary cooling tube 3 through the connecting column 302, and is sprayed toward the motor controller body 1 again under the action of multiple second nozzles 301 on the auxiliary cooling tube 3, thereby greatly improving the cooling effect on the motor controller body 1, avoiding high temperature of the motor controller body 1, and also ensuring the service life of the motor controller body 1.

[0072] The liquid contained in the high-pressure airflow is absorbed by the cooling liquid 211 and will not affect the motor controller body 1, thereby ensuring the safety of the motor controller body 1. At the same time, through the action of the liquid pump 4 and the reflux pipe 207, the cooling liquid 211 in the second containing box 206 can also enter the filling chamber 209 to replenish the cooling liquid 211 in the filling chamber 209, thereby realizing the recycling of the cooling liquid 211 and avoiding the waste of the cooling liquid 211.
