Description

Technical Field

[0001] This utility model relates to the field of driver testing box technology, specifically a driver simulation testing hot air box. Background Technology

[0002] A driver is an electronic device used to control and drive the operation of a motor. It receives control signals and converts them into the voltage and current required by the motor to regulate its speed, direction, and torque. When designing a driver, factors such as voltage, current, speed, torque, direction, heat dissipation, and communication methods need to be considered initially.

[0003] The driver is located at the middle of the main control box-driver-motor transition in the entire control process. Its main function is to receive signals from the main control box, process the signals and transfer them to the motor and related sensors, and feed back the motor's operating status to the main control box.

[0004] When testing a driver, it is necessary to simulate its operating temperature environment to detect its comprehensive performance in a high-temperature environment and determine its working performance. Traditional driver environment simulation devices are mostly complex in internal structure, cumbersome in operation, difficult to manufacture, and have high initial purchase and maintenance costs, which further increases the economic burden on manufacturing enterprises. Therefore, this utility model proposes a relatively simple driver simulation testing hot air box. Utility Model Content

[0005] The purpose of this invention is to provide a driver for simulating the detection of a hot air box, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a driver simulation testing hot air box, comprising a hot air box body, an inner hot air chamber inside the hot air box body, a test workbench inside the inner hot air chamber, two upper top plates fixedly installed at the top of the inner hot air chamber, and a draft volute fixedly installed above each of the two upper top plates, draft blades inside the draft volute, and a heating plate fixedly installed on one side of the draft volute, forming the internal hot air structure of the hot air box between the upper top plates, the draft volute, and the heating plate, and an air outlet plate fixedly installed at the air outlet of the draft volute.

[0007] Preferably, a drive motor is fixedly installed directly above the two air intake volutes and on the outer surface of the hot air box.

[0008] Preferably, the output shaft of the drive motor is fixedly connected to the rotating shaft of the air-driving blades inside the air-driving volute.

[0009] Preferably, the exterior of the inner hot air chamber is provided with two positively sealed doors, which are movably hinged to the hot air box body via hinges.

[0010] Preferably, each of the two positively sealed doors has a viewing window on its outer surface, and the viewing window is fitted with transparent explosion-proof tempered glass.

[0011] Preferably, both sides of the hot air box are hinged to side doors, and an explosion-proof lock is fixedly installed at the top of each side door.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The hot air box for simulating driver operation has a simple overall structure and can easily simulate the working environment temperature of the driver. This facilitates performance testing of the driver by simulating the working environment temperature. It only requires a heating plate and an air intake structure, making it easy to use, inexpensive to manufacture, and simple to operate. It effectively reduces the initial purchase cost and subsequent maintenance cost of the hot air box machine, thereby alleviating the economic burden on enterprises. It has good practicality and is suitable for small and micro enterprises to purchase and use.

[0014] Meanwhile, the air intake structure of this utility model adopts an air intake volute structure design, which can guide the airflow to flow out evenly when hot air is introduced, improving the uniformity of hot air output. This makes the internal temperature rise curve of the inner hot air chamber more uniform, avoiding the actual use situation of large local temperature differences. The hot air coverage is more uniform, improving practicality. At the same time, it can reduce airflow turbulence and eddy loss, improving air intake efficiency. Furthermore, this utility model adopts a dual hot air heating air intake structure, which can quickly raise the internal temperature of the inner heating chamber to the preset detection temperature, thereby effectively improving the heating and temperature rise speed of this utility model, improving heating efficiency, and having good practicality.

[0023] Please see Figure 1-4 The present invention provides an embodiment of a driver simulation test hot air box, including a hot air box body 1, and an inner hot air chamber 2 is provided inside the hot air box body 1. In order to place the driver that needs to be tested by temperature environment simulation, a test workbench (not shown in the figure) is provided inside the inner hot air chamber 2.

[0024] Please refer to the instruction manual for details. Figure 3 and Figure 4As shown, two upper top plates 3 are fixedly installed at the top of the inner hot air chamber 2. A volute 5 is fixedly installed above each of the two upper top plates 3. The volute 5 is equipped with air duct blades inside. A heating plate 6 is fixedly installed on one side of the volute 5. The upper top plate 3, the volute 5 and the heating plate 6 form the internal hot air structure of the hot air box. An air outlet plate 4 is fixedly installed at the air outlet of the volute 5.

[0025] This structural design allows the heating plate 6 to heat the internal environment of the top plate 3, thereby raising the temperature of the air inside to meet the testing temperature conditions. At the same time, the air duct 5 inside the air duct can rotate and introduce the high-temperature air into the inner heating chamber 2, thereby raising the temperature of the inner heating chamber 2. This can simulate the temperature of the driver under working conditions, and thus test the comprehensive performance of the driver under working temperature conditions. It has a good practical effect in driver simulation testing.

[0026] Meanwhile, in actual use, the simulated detection temperature can be controlled by controlling the heating effect of the heating plate 6, thereby simulating the specific performance of the driver under different temperature environments, and has good detection usability.

[0027] Furthermore, in order to drive the blades inside the induced draft volute 5 to rotate, a drive motor 7 is fixedly installed directly above the two induced draft volutes 5 and on the outer surface of the hot air box 1. The output shaft of the drive motor 7 is fixedly connected to the rotating shaft of the induced draft blades inside the induced draft volute 5.

[0028] In this embodiment, in order to seal the interior of the inner hot air chamber 2 during testing, two positive sealing doors 9 are provided on the outside of the inner hot air chamber 2. The two positive sealing doors 9 are hinged to the hot air box body 1.

[0029] In order to improve the visualization effect and facilitate the perspective observation of the testing and inspection process, visualization windows are set on the outer surfaces of the two positively sealed doors 9, and transparent explosion-proof tempered glass is fixedly installed inside the visualization windows.

[0030] In this embodiment, in order to improve the side opening effect of the box, side doors 10 are hinged to both outer walls of the hot air box 1, and explosion-proof locks are fixedly installed on the top of the side doors 10.

[0031] Working principle: When using this utility model, the inner hot air chamber 2 can be opened through the two positive sealing doors 9, and then the driver that needs to be tested for temperature simulation can be placed on the test workbench, and then the positive sealing doors 9 can be closed.

[0032] At this time, the heating plate 6 can be put into operation. The heating plate 6 can heat the internal environment of the top plate 3, thereby raising the temperature of the air inside to meet the test temperature conditions. At the same time, the air duct 5 can rotate and introduce the high-temperature air inside into the inner heating chamber 2, thereby raising the temperature of the inner heating chamber 2. This can simulate the temperature of the driver in the working environment, and thus test the comprehensive performance of the driver in various aspects under the working temperature environment, which has a good practical effect of driver simulation test.

[0033] Meanwhile, in actual use, the simulated detection temperature can be controlled by controlling the heating effect of the heating plate 6, thereby simulating the specific performance of the driver under different temperature environments, and has good detection usability.

[0034] The hot air box for simulating driver operation has a simple overall structure and can easily simulate the working environment temperature of the driver. This facilitates performance testing of the driver by simulating the working environment temperature. It only requires a heating plate and an air intake structure, making it easy to use, inexpensive to manufacture, and simple to operate. It effectively reduces the initial purchase cost and subsequent maintenance cost of the hot air box machine, thereby alleviating the economic burden on enterprises. It has good practicality and is suitable for small and micro enterprises to purchase and use.

[0035] Meanwhile, the air intake structure of this utility model adopts an air intake volute structure design, which can guide the airflow to flow out evenly when hot air is introduced, improving the uniformity of hot air output. This makes the internal temperature rise curve of the inner hot air chamber more uniform, avoiding the actual use situation of large local temperature differences. The hot air coverage is more uniform, improving practicality. At the same time, it can reduce airflow turbulence and eddy loss, improving air intake efficiency. Furthermore, this utility model adopts a dual hot air heating air intake structure, which can quickly raise the internal temperature of the inner heating chamber to the preset detection temperature, thereby effectively improving the heating and temperature rise speed of this utility model, improving heating efficiency, and having good practicality.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
