Description

Technical Field

[0001] This utility model relates to the field of regulator technology, specifically to a regulator with temperature protection function. Background Technology

[0002] With increasing customer demand for electricity, lithium batteries are being used more and more widely in traditional gasoline vehicles, posing more stringent challenges to traditional generators. Due to the characteristics of lithium batteries, generators will remain at full load when charging a depleted lithium battery. When the lithium battery capacity is large but the charge level is low, the generator will remain at full load for an extended period. This will cause the stator enameled copper wires to be exposed to high temperatures for a long time, severely shortening their lifespan and eventually leading to burnout and failure to generate electricity. Therefore, accurate monitoring and effective regulation of their temperature are extremely crucial.

[0003] Currently, most regulators on the market used for detecting the temperature of generator stator enameled wire use thermistors as temperature sensing elements. In traditional solutions, two separate terminals must be led out from the regulator and connected to the thermistor to transmit the temperature signal. Furthermore, the thermistor cannot directly contact the stator core; instead, it is connected to the stator core through a specific medium. However, this design has significant drawbacks. The separate terminal leads not only increase the complexity of the wiring layout and raise production costs but also occupy limited internal space. Simultaneously, fluctuations in the thermal conductivity and aging of the medium connecting the thermistor and the stator core can interfere with the accuracy and stability of temperature detection, leading to data deviations and failing to provide effective temperature protection for the generator stator. Therefore, this invention provides a regulator with integrated temperature protection functionality. Utility Model Content

[0004] To address the aforementioned issues, a regulator with temperature protection function is provided. This is achieved by creating a groove on the regulator body, with a matching rear cover plate on the groove. An integrated circuit is housed within the cavity formed by the rear cover plate and the groove. A boss is located on the rear cover plate, and a temperature sensor is positioned at the lower end of the boss. The temperature sensor contacts the copper wires on the stator assembly, detecting their temperature and transmitting this information to the integrated circuit. The integrated circuit controls the generator's duty cycle. When the temperature sensor detects that the copper wire temperature is too high, the integrated circuit increases the duty cycle, reducing the generator's power output to cool it down, thus achieving temperature protection. This solution solves the problem of complex wiring layouts caused by installing thermistors on the stator assembly copper wires in traditional generators, with the thermistors connected via two terminals on the regulator.

[0005] To address the problems of existing technologies, this utility model provides a regulator with temperature protection function, including a regulator body, a rear cover plate, an integrated circuit, and a temperature sensor. A groove is provided on the lower surface of the regulator body. The rear cover plate can be connected to the edge of the groove and cooperates with the groove to form a cavity structure. The integrated circuit is disposed within the cavity structure. A boss is provided on the rear cover plate. The boss has a hollow structure. The temperature sensor is disposed at the lower end within the boss. The temperature sensor is connected to the integrated circuit via a wire. The probe of the temperature sensor can contact the copper wire on the stator assembly of the generator.

[0006] Preferably, the temperature sensor is connected to the integrated circuit via two sensor wires.

[0007] Preferably, the rear cover plate and the boss are an integral structure, and the hollow structure of the boss can communicate with the cavity structure.

[0008] Preferably, the regulator body has connection holes at both ends and a connection post on the generator rear cover. The connection holes can be fitted onto the connection post, and the regulator body can be fixed to the generator rear cover by screws connecting it to the connection post.

[0009] Preferably, the regulator body can be bolted to the generator rear cover, the generator rear cover is provided with a through hole, and the boss can penetrate the through hole to contact the copper wire on the stator assembly.

[0010] Preferably, the temperature sensor is confined within the lower end of the boss by a medium, and the lower end of the boss is provided with an opening.

[0011] Preferably, the temperature sensor is confined to the lower end of the boss, and the thickness of the inner wall of the boss at the point of contact with the temperature sensor is within 2 mm.

[0012] Preferably, the rear cover plate is provided with a threaded hole, the upper end of the boss is provided with an external thread, the boss can be screwed onto the rear cover plate, and the hollow structure of the boss can communicate with the cavity structure.

[0013] The advantages of this utility model compared to the prior art are:

[0014] An integrated circuit is housed within a cavity formed by a groove on the regulator body and a matching rear cover plate. A boss is located on the rear cover plate, and a temperature sensor is positioned at the lower end of the boss. The temperature sensor contacts the copper wires on the stator assembly, detects their temperature, and transmits this information to the integrated circuit. The integrated circuit then controls the generator's duty cycle. When the temperature sensor detects that the copper wire temperature is too high, the integrated circuit increases the duty cycle, reducing the generator's power output to cool the generator and thus achieving temperature protection.

Detailed Implementation

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figure 1-6As shown, a regulator with temperature protection function includes a regulator body 3, a rear cover plate 4, an integrated circuit 6, and a temperature sensor 7. A groove is provided on the lower surface of the regulator body 3. The rear cover plate 4 can be connected to the edge of the groove and cooperates with the groove to form a cavity structure 30. The integrated circuit 6 is disposed within the cavity structure 30. A boss 5 is provided on the rear cover plate 4. The boss 5 is a hollow structure 50. The temperature sensor 7 is disposed at the lower end within the boss 5 and is connected to the integrated circuit 6 via a wire. The regulator with temperature protection function is mounted on the generator rear cover 1, and the lower end of the boss 5 is close to the copper wire on the generator stator assembly 2. Figure 1 As shown, the lower end of the boss 5 is close to the copper wire on the stator assembly 2, so that the probe of the temperature sensor 7 can directly sense the temperature of the copper wire on the stator assembly 2. During the operation of the generator, the copper wire of the stator assembly 2 will generate heat. The heat on the copper wire can be transferred to the temperature sensor 7 through the boss 5. The temperature sensor 7 is connected to the integrated circuit 6. The integrated circuit 6 adjusts the duty cycle of the generator by measuring the temperature value. That is, in the generator control system, the integrated circuit adjusts the output voltage, current or power of the generator by precisely controlling the ratio of the on and off time of the power switching element, thereby achieving the effect of cooling the copper wire on the stator assembly 2.

[0024] It should be noted that a temperature range (X, Y) is preset in integrated circuit 6. When the temperature sensor 7 detects that the temperature on the stator assembly 2 is less than X, integrated circuit 6 controls the duty cycle to be 0 and the generator's power output to be 100%. When the temperature sensor 7 detects that the temperature on the stator assembly 2 is greater than X but less than Y, integrated circuit 6 controls the generator's duty cycle to increase, causing the generator's power output to decrease, thereby causing the generator's temperature to decrease. The value of Y should be less than the maximum withstand temperature of the copper wires in the stator assembly 2.

[0025] Temperature sensor 7 is connected to integrated circuit 6 via two sensor wires 70. Two contacts are led out from integrated circuit 6 to connect to the sensor wires 70.

[0026] The rear cover plate 4 and the boss 5 are an integral structure, and the hollow structure 50 of the boss 5 can communicate with the cavity structure 30. The rear cover plate 4 and the boss 5 are set as an integral structure, and the rear cover plate 4 and the boss 5 are formed by integral stamping, which is convenient for processing.

[0027] The regulator body 3 has connection holes 31 at both ends, and a connecting post 10 is provided on the generator rear cover 1. The connection holes 31 can be fitted onto the connecting post 10. The regulator body 3 is secured to the generator rear cover 1 by screws connected to the connecting post 10. Figure 2 As shown, the connection between the connecting post 10 and the connecting hole 31 allows the regulator body 3 to be detachably connected to the generator rear cover 1.

[0028] The regulator body 3 can be bolted to the generator rear cover 1. The generator rear cover 1 is provided with a through hole 11, and the boss 5 can penetrate the through hole 11 to contact the copper wires on the stator assembly 2. The boss 5 penetrates the through hole 11 to contact the copper wires on the stator assembly 2. The through hole 11 not only allows the boss 5 to enter, but also plays a role in heat dissipation of the generator.

[0029] Temperature sensor 7 is confined within the lower end of boss 5 by a medium, and boss 5 has an opening at its lower end. For example, by adhering temperature sensor 7 to the lower end of boss 5, it prevents the temperature sensor 7 from shaking within the hollow structure 50 of boss 5 during generator operation or when the regulator body 3 is moved, thus preventing the temperature sensor 7 from accurately monitoring the copper wire temperature of stator assembly 2. The opening at the lower end of boss 5 facilitates the transfer of temperature from the copper wire to temperature sensor 7.

[0030] The temperature sensor 7 is confined within the lower end of the boss 5, and the thickness of the inner wall of the boss 5 at the contact point with the temperature sensor 7 is less than 2mm. The relatively thin inner wall of the boss 5 allows the temperature on the copper wire to be transferred to the temperature sensor 7 quickly and accurately.

[0031] The rear cover plate 4 has threaded holes, and the upper end of the boss 5 has external threads. The boss 5 can be screwed onto the rear cover plate 4, and the hollow structure 50 of the boss 5 can communicate with the cavity structure 30. The boss 5 and the rear cover plate 4 are designed to be detachable, which facilitates the replacement of the parts inside.

[0032] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
