[0038] Example 1

[0039] This utility model embodiment provides a relay detection device. Figure 1 This is a schematic diagram of a relay detection device provided in Embodiment 1 of this utility model. (Reference) Figure 1The relay detection device includes: a relay 1, a conductive element 7, at least one detection module 4, a control module 5, and a connection status determination module 6. The relay 1 is connected between the power supply module 2 and the electrical load 3 via the conductive element 7. The relay 1 is used to connect or disconnect the connection between the power supply module 2 and the electrical load 3, and the conductive element 7 is used to transmit electrical energy. The detection module 4 is clamped at the connection point between the relay 4 and the conductive element 7. The detection module 4 is used to detect at least one of the pressure and temperature between the relay 1 and the conductive element 7, and outputs at least one of the pressure analog signal and the temperature analog signal accordingly. The control module 5 is connected to the detection module 4. The control module 5 is used to generate a temperature digital signal based on the temperature analog signal, and / or, the control module 5 is used to generate a pressure digital signal based on the pressure analog signal. The connection status determination module 6 is communicatively connected to the control module 5 and is used to determine the connection status between the relay 1 and the conductive element 7 based on the temperature digital signal and / or the pressure digital signal.

[0040] The conductive component 7 is connected in the power supply path between the power supply module 2 and the electrical load 3, and controls the on / off state of the power supply path via the relay 1. During use, the conductive component 7 may experience deformation, oxidation of the connection surface, etc., which can degrade the reliability of the connection between the conductive component 7 and the relay 1, leading to increased internal resistance at the connection point, and may even cause the conductive component 7 and the relay 1 to burn out due to increased temperature. For example, the conductive component 7 may include a sheet-like copper busbar.

[0041] By clamping the detection module 4 at the connection point between the relay 1 and the conductive component 7, the connection status between the relay 1 and the conductive component 7 can be detected without affecting the connection between the conductive component 7 and the relay 1. Figure 1 An exemplary connection detection device with two detection modules 4 is shown, which can simultaneously detect two connection positions between the relay 1 and the conductive element 7.

[0042] Specifically, the detection module 4 can be used to detect the pressure between the relay 1 and the conductive component 7 and generate a pressure analog signal. The pressure analog signal may include a resistance signal. The control module 5 can be used to acquire the pressure analog signal generated by the detection module 4 in real time and generate a pressure digital signal. When the connection status judgment module 6 receives the pressure digital signal, the connection status judgment module 6 can judge the pressure between the relay 1 and the conductive component 7.

[0043] The connection status judgment module 6 can compare the digital pressure signal with the initial pressure signal, which represents the initial value of the connection pressure between relay 1 and conductive component 7 after the first connection. When the digital pressure signal is less than or equal to 75% of the initial pressure signal, it indicates that there is a connection problem such as unstable connection or connection failure between relay 1 and conductive component 7.

[0044] The detection module 4 can also detect the temperature between the relay 1 and the conductive component 7 and generate a temperature analog signal. The temperature analog signal may include a resistance signal. The control module 5 acquires the temperature analog signal generated by the detection module 4 in real time and generates a temperature digital signal. When the connection status judgment module 6 receives the temperature digital signal, the connection status judgment module 6 can judge the temperature between the relay 1 and the conductive component 7.

[0045] The connection status judgment module 6 can compare the temperature digital signal with a preset temperature, which can be, for example, 110 degrees Celsius. When the temperature digital signal is greater than the preset temperature, it indicates that there is a connection problem such as unstable connection or connection failure between the relay 1 and the conductive part 7.

[0046] The detection module 4 can also simultaneously detect the pressure and temperature between the relay 1 and the conductive component 7, and generate simulated pressure and temperature signals. The control module 5 acquires the simulated pressure and temperature signals in real time and generates digital pressure and temperature signals. When the connection status judgment module 6 receives the digital pressure and temperature signals, it can determine the pressure and temperature between the relay 1 and the conductive component 7.

[0047] If the pressure digital signal is less than or equal to 75% of the initial pressure signal and / or the temperature digital signal is greater than the preset temperature, it indicates that there is a connection problem such as unstable connection or connection failure between relay 1 and conductive component 7.

[0048] The technical solution provided by this utility model embodiment achieves the detection of pressure and / or temperature between the relay and the conductive component by clamping the detection module at the connection position between the relay and the conductive component, and generates analog pressure signals and / or analog temperature signals. Furthermore, by setting a control module, the analog pressure signals and / or analog temperature signals can be converted into digital pressure signals and digital temperature signals, respectively. The connection status judgment module can determine whether the connection between the relay and the conductive component is stable or whether there are connection problems such as faults through the digital pressure signals and / or digital temperature signals, thereby realizing the detection of the connection status between the relay and the conductive component. Therefore, this utility model can achieve the detection of the connection status between the relay and the conductive component with a simple structure without damaging the original circuit structure, and has a good detection effect.

[0049] Example 2

[0050] Figure 2 This is a schematic diagram of a detection module provided in Embodiment 2 of this utility model. (Reference) Figure 2Based on the above embodiments, optionally, the detection module 4 includes: a detection element 41 and at least one signal lead 42. The detection element 41 is clamped at the connection position between the relay 1 and the conductive element 7. The first end of the signal lead 42 is connected to the detection element 41, and the second end of the signal lead 42 is connected to the control module 5. The signal lead 42 includes: a pressure signal lead 422 and / or a temperature signal lead 421.

[0051] Among them, the detection element 41 is a thin sheet structure that can be clamped between the relay 1 and the conductive element 7. When the pressure between the relay 1 and the conductive element 7 changes, or when the conductive element 7 deforms, the detection element 41 will deform differently due to the pressure of different forces, thereby generating a pressure simulation signal, which is output to the control module 5 through the signal lead 42. At this time, the signal lead 42 used to transmit the pressure simulation signal is the pressure signal lead 422.

[0052] The detection element 41 can also be used to detect the temperature between the relay 1 and the conductive element 7 and generate a temperature simulation signal. This temperature simulation signal can be output to the control module 5 through the signal lead 42. At this time, the signal lead 42 used to transmit the temperature simulation signal is the temperature signal lead 421.

[0053] This utility model embodiment can detect the temperature and pressure between the relay and the conductive component by setting a detection element. The detection element can be clamped at the connection position between the relay and the conductive component, has a small volume, and does not affect the connection reliability between the relay and the conductive component, thus having a good detection effect.

[0054] Continue to refer to Figure 2 Based on the above embodiments, optionally, the detection element 41 includes: a pressure sensor connected to the first end of the pressure signal lead 422; and / or a surface-mount thermistor connected to the first end of the temperature signal lead 421.

[0055] In its normal state, the pressure sensor operates at high resistance, essentially functioning as an open circuit. When external pressure on the sensor surface reaches a certain threshold, it is triggered to conduct and generate a simulated pressure signal, which can be a resistance signal. As the external pressure increases, this resistance signal decreases according to a specific characteristic curve. Therefore, by detecting this resistance signal, the pressure between relay 1 and conductive component 7 can be determined.

[0056] The sensing element 41 may also include a surface-mount thermistor. Exemplarily, the surface-mount thermistor can be integrated into the pressure sensor to detect the temperature between the relay 1 and the conductive element 7 and generate a temperature analog signal. The surface-mount thermistor can be an NTC (Negative Temperature Coefficient) thermistor, in which case the temperature analog signal is a resistance signal. This resistance signal decreases as the external temperature increases.

[0057] Figure 2 An exemplary detection module is shown, comprising two temperature signal leads 421 and two pressure signal leads 422. The two temperature signal leads 421 form a signal path with the control module 5 for transmitting analog temperature signals, and the two pressure signal leads 422 form a signal path with the control module 5 for transmitting analog pressure signals. In other embodiments, the two temperature signal leads 421 may be combined into a single temperature signal lead bundle, thereby forming a signal path for transmitting analog temperature signals. Similarly, the two pressure signal leads 422 may be combined into a single pressure signal lead bundle, thereby forming a signal path for transmitting analog pressure signals.

[0058] The detection device provided in this embodiment of the invention enables the detection of temperature and pressure between the relay and the conductive component. By integrating the chip thermistor into the pressure sensor, the size of the detection device is further reduced, thus minimizing the impact on the connection between the relay and the conductive component.

[0059] Example 3

[0060] Figure 3 This is a partial structural schematic diagram of a relay detection device provided in Embodiment 3 of this utility model. Figure 4 This is a partial structural schematic diagram of another relay detection device provided in Embodiment 3 of this utility model. (In conjunction with...) Figure 3 and Figure 4 Based on the above embodiments, optionally, the conductive element 7 includes: a first opening 71; the detection element 41 includes: a second opening 411; the relay 1 includes: a third opening 11; and the connector 8 is sequentially inserted through the first opening 71 and the second opening 411 and then fixed in the third opening 11.

[0061] During installation, the detection component 41 can be clamped between the conductive component 7 and the relay 1. After aligning the center points of the first opening 71, the second opening 411, and the third opening 11, it can be fixedly connected using the connector 8. This arrangement maximizes the installation stability of the detection component 41 and provides a good clamping effect.

[0062] Figure 3 and Figure 4 The example shown illustrates a conductive element 7 with a first opening 71, which is not intended to limit the present invention. In other embodiments, a conductive element 7 may have multiple first openings 71, and each first opening 71 is fixed to a third opening 11 by a connector 8.

[0063] Figure 5 This is a schematic diagram of a detection module provided in Embodiment 3 of this utility model. (Reference) Figure 5 Based on the above embodiments, optionally, the detection element 41 includes: at least two pressure sensors 412, and / or at least two surface-mount thermistors 413; at least two pressure sensors 412 are spaced apart around the second opening 411; and / or at least two surface-mount thermistors 413 are spaced apart around the second opening 411.

[0064] In order to improve the detection accuracy of the connection between the conductive component 7 and the detection component 41, multiple pressure sensors 412 and / or chip thermistors 413 can be set in the detection component 41 to obtain more temperature and pressure analog signal data. Figure 5 An exemplary detection element 41 is shown, having three chip thermistors 413 and three pressure sensors 412, which can generate three temperature analog signals and three pressure analog signals, and transmit the signals through three temperature signal leads 421 and three pressure signal leads 422 respectively. Figure 5 The dashed box in the figure only illustrates the exemplary location of the chip thermistor 413 and pressure sensor 412 within the sensing element 41 and does not represent the specific structure of the chip thermistor 413 and pressure sensor 412. In other embodiments, a chip thermistor 413 may also be integrated into a pressure sensor 412 and located in the same position.

[0065] When multiple pressure sensors 412 are installed, if only some of the pressure digital signals are less than or equal to 75% of the initial pressure signal, it indicates that the connection between relay 1 and conductive element 7 is unstable. If the pressure digital signals at multiple locations are all less than or equal to 75% of the initial pressure signal, it indicates that there is a fault in the connection between relay 1 and conductive element 7.

[0066] When multiple surface-mount thermistors 413 are used, if only some of the temperature digital signals are greater than the preset temperature, it indicates that the connection between relay 1 and conductive component 7 is unstable. If the temperature digital signals at multiple locations are greater than the preset temperature, it indicates that there is a fault in the connection between relay 1 and conductive component 7.

[0067] When multiple pressure sensors 412 and surface-mount thermistors 413 are provided, if only some pressure digital signals are less than or equal to 75% of the initial pressure signal, or if only some temperature digital signals are greater than the preset temperature, it indicates that the connection between relay 1 and conductive component 7 is unstable. If multiple pressure digital signals are less than or equal to 75% of the initial pressure signal, and multiple temperature digital signals are greater than the preset temperature, it indicates that there is a fault in the connection between relay 1 and conductive component 7.

[0068] This invention improves the detection accuracy of the connection status between the relay and the conductive component by setting multiple pressure sensors and / or multiple chip thermistors in the detection component, and has a better calibration effect.

[0069] Continue to refer to Figure 4 Based on the above embodiments, optionally, the connector 8 includes a bolt, and the third opening 11 includes a threaded hole. Alternatively, the connector 8 includes a pin, and the third opening 11 includes a pin hole.

[0070] Continue to combine Figure 3 and Figure 4 Based on the above embodiments, optionally, the relay 1 includes at least two third openings 11, and the conductive element 7 includes a first conductive element 72 and a second conductive element 73. The first conductive element 72 is connected to one of the third openings 11 via a connector 8; the first conductive element 72 is connected between the third opening 11 and the power supply module 2. The second conductive element 73 is connected to the other third opening 11 via the connector 8; the second conductive element 73 is connected between the other third opening 11 and the electrical load 3. The relay 1 is used to connect or disconnect the power supply between the first conductive element 72 and the second conductive element 73.

[0071] Each of the third openings 11 can be equipped with a corresponding detection element 41, and each detection element 41 can also be equipped with multiple pressure sensors 412 and / or multiple chip thermistors 413, thereby realizing the judgment of the connection status between each of the third openings 11 of the relay 1 and the conductive element 7.

[0073] Figure 6 This is a schematic diagram of the structure of a relay detection device provided in Embodiment 4 of this utility model. (Reference) Figure 6 Based on the above embodiments, optionally, the relay detection device further includes: a connection status receiving module 9, which is communicatively connected to the connection status judging module 6, for receiving the connection status between the relay 1 and the conductive component 7.

[0074] The connection status receiving module 9 can be used to guide fault handling based on the connection status between the relay 1 and the conductive component 7. For example, when there is a fault in the connection between the relay 1 and the conductive component 7, the connection status receiving module 9 can provide an operational suggestion to power off the power supply module 2 and remind relevant personnel to check the connection status between the relay 1 and the conductive component 7.

[0075] Continue to refer to Figure 6 Based on the above embodiments, optionally, the connection status receiving module 9 is communicatively connected to the connection status determining module 6 via a controller area network (CLAN) bus. The connection status determining module 6 is communicatively connected to the control module 5 via a CLAN bus.

[0076] For example, control module 5 may include an MCU (Microcontroller Unit), which can acquire analog pressure and temperature signals in real time, convert them into digital pressure and temperature signals through internal software, and then transmit the digital pressure and temperature signals to status judgment module 6 via a controller area network bus (CAN bus). Status judgment module 6 may include a BMS (Battery Management System), which can be used to analyze the digital pressure and temperature signals in real time and determine the connection status. After determining the connection status between relay 1 and conductive component 7, status judgment module 6 can transmit the determination result to connection status receiving module 9 via the controller area network bus.

[0077] The communication method of the controller area network bus has the characteristics of high reliability, strong anti-interference ability and good real-time performance, which can improve the stability of signal transmission between various modules.
