[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0030] The powertrain is mounted on the vehicle through a suspension. The powertrain suspension will ensure that the powertrain is positioned in its designed static position and that the position is correct during the normal service life of the vehicle. At the same time, by isolating the powertrain from the vehicle body, the powertrain movement and the reaction force and torque from the powertrain are controlled, thereby achieving the effect of attenuating the force and torque generated by the powertrain and the external road input force. The suspension is usually installed between the powertrain and the frame / subframe. The structural types include rubber suspension, hydraulic suspension, semi-active suspension, etc. Since one end of the suspension is connected to the powertrain and the other end is connected to the frame chassis, after the suspension breaks, the powertrain is not restricted in its position in the vehicle, posing a serious threat to the safety of the vehicle and the occupants. Therefore, it is very necessary to study the suspension fracture feedback system.
[0031] See also Figure 1 As shown, the embodiment of the utility model provides a suspension fracture feedback module, including: a suspension conductor X1 and a fracture feedback circuit.
[0032] In this embodiment, the suspension conductor X1 is arranged at the suspension and is broken when the suspension is broken.
[0033] In a possible implementation, the arrangement of the suspension wire X1 can be as follows: Figure 2 As shown, the suspension includes a first connection part A1 connected to the vehicle chassis and a second connection part A2 connected to the vehicle powertrain. The suspension wire X1 surrounds the first connection part A1 and the second connection part A2 as a whole, and one end is connected to the second end of the resistor R in the suspension fracture feedback module M1, and the other end is connected to the negative electrode of the power source C2. When the suspension skeleton is broken, the distance between the first connection part A1 and the second connection part A2 increases, and the suspension wire X1 is torn off, realizing the function that the suspension wire X1 breaks when the suspension breaks.
[0034] In another possible implementation, the arrangement of the suspension wire X1 can be as follows: Figure 3 As shown, one end of the suspension wire X1 is arranged at the first connection part A1 and connected to the second end of the resistor R, and the other end is arranged at the second connection part A2 and connected to the negative electrode of the power supply C2. Similarly, when the suspension frame is broken, the distance between the first connection part A1 and the second connection part A2 increases, and the suspension wire X1 is torn off, realizing the function that the suspension wire X1 is broken when the suspension is broken.
[0035] In the above two implementations, in order to accurately monitor the suspension breakage situation, the suspension wire X1 should be in a taut state. Figure 2 and Figure 3 It is only an exemplary arrangement. The arrangement of the suspension wire X1 and the position of the suspension break feedback module M1 can be designed according to actual needs. As long as the suspension wire X1 can break when the suspension breaks, this embodiment does not limit this.
[0036] Optionally, the fracture feedback circuit includes a power supply C2, a resistor R, a three-terminal thyristor switch D2, a first diode D1 and a signal transmission port C1.
[0037] The positive electrode of the power supply C2 is connected to the first connection end of the three-terminal thyristor switch D2, the second connection end of the three-terminal thyristor switch D2 is connected to the first end of the signal transmission port C1, and the second end of the signal transmission port C1 is connected to the negative electrode of the power supply C2; the positive electrode of the power supply C2 is also connected to the first end of the resistor R, and the second end of the resistor R is connected to the negative electrode of the power supply C2 through the suspension wire X1 in one way and connected to the input end of the first diode D1 in the other way, and the output end of the first diode D1 is connected to the control end of the three-terminal thyristor switch D2.
[0038] In this embodiment, when the suspension is not broken, the suspension wire X1 is connected normally, and the voltage between X1 and D1 is 0V. Therefore, the current at the positive electrode of the power supply C2 flows back to the negative electrode of the power supply C2 through the resistor R and the suspension wire X1, and no current passes through the first diode D1. There is no trigger voltage at the control end of the three-terminal thyristor switch D2, the three-terminal thyristor switch D2 remains in the cut-off state, the signal transmission port C1 loop is blocked, and the suspension break feedback module M1 has no signal output.
[0039] When the suspension skeleton breaks, the suspension wire X1 breaks accordingly, and the current of the positive electrode of the power supply C2 flows to the control end of the three-terminal thyristor switch D2 through the resistor R and the first diode D1, and the three-terminal thyristor switch D2 changes from the cut-off state to the on state, and the current outputs a signal through the signal transmission port C1, thereby realizing timely and accurate monitoring of the suspension fracture. Here, the three-terminal thyristor switch D2 can be a unidirectional three-terminal thyristor switch to prevent the current from being reversely conducted, and the first connection end of the three-terminal thyristor switch D2 is the input end, and the second connection end of the three-terminal thyristor switch D2 is the output end.
[0040] The on / off state of the three-terminal bidirectional thyristor D2 is determined by the control end. Adding a positive pulse or a negative pulse to the control end can turn it on. The thyristor can only be turned off by disconnecting the anode power supply. The advantage of this device is that the control circuit is simple, there is no reverse withstand voltage problem, and it is suitable for use as a contactless switch. Due to the characteristics of the three-terminal thyristor switch D2, after it is turned on, even if the suspension wire X1 accidentally contacts and reconnects, D2 still maintains the on state. Only when the anode power supply of D2 is disconnected, D2 will return to the off state. In this way, continuous alarm can be achieved to prevent the problem of alarm release caused by accidental contact of the suspension wire X1 due to bumps and shaking when the vehicle is driving, thereby improving the reliability of the module.
[0041] It can be seen that the embodiment of the utility model arranges the suspension wire at the suspension. When the suspension is normal, the suspension wire is not broken, the current of the positive pole of the power supply flows back to the negative pole of the power supply through the resistor and the suspension wire, the control end of the three-terminal thyristor switch has no trigger voltage, the three-terminal thyristor switch remains in the cut-off state, the signal transmission port loop is blocked, and the suspension fracture feedback module has no signal output; when the suspension skeleton is broken, the suspension wire is broken accordingly, the current of the positive pole of the power supply flows to the control end of the three-terminal thyristor switch through the resistor and the first diode, the three-terminal thyristor switch changes from the cut-off state to the on state, and the current outputs the signal through the signal transmission port, thereby realizing timely and accurate monitoring of the suspension fracture. At the same time, due to the characteristics of the three-terminal thyristor switch, even if the suspension wire is accidentally contacted and reconnected after it is turned on, the three-terminal thyristor switch still maintains the on state, ensuring that the module continues to output signals in this case, further improving the safety and reliability of the module.
[0042] Since the three-terminal thyristor switch D2 is turned on, even if the suspension wire X1 is reconnected, D2 still maintains the on state. In order to facilitate the alarm to be released after the suspension and the suspension wire X1 are repaired, the present embodiment further designs the following Figure 4 The scheme shown.
[0043] exist Figure 4 In the embodiment, a module switch LS1 is also provided on the main loop of the fracture feedback circuit. Figure 4 In the embodiment, the module switch LS1 is set at the positive pole of the power supply C2. It is understandable that the module switch LS1 can also be set at the negative pole of the power supply C2, at the two connection ends of the three-terminal thyristor switch D2, etc. The module switch LS1 is used to control the power on and off of the suspension break feedback module M1. Specifically, when the suspension wire X1 breaks and the system alarms, the maintenance personnel turn off the module switch LS1, repair or replace the suspension and the suspension wire X1, and then turn on the module switch LS1. Since the module switch LS1 is opened and closed again, the three-terminal thyristor switch D2 is reset and becomes cut-off again.
[0044] In this embodiment, the three-terminal thyristor switch D2 can be a bidirectional three-terminal thyristor switch. In this case, a second diode D3 needs to be added between the power supply C2 and the three-terminal thyristor switch D2 to prevent the current from being reversely conducted. The positive electrode of the power supply C2 is connected to the input end of the second diode D3, and the output end of the second diode D3 is connected to the first connection end of the three-terminal thyristor switch D2. The detailed operating principle of the fracture feedback circuit can be seen in Figure 1 The description in the embodiments will not be repeated in this embodiment.
[0045] Figure 5 Schematic diagram of the structure of the suspension fracture feedback system provided in this embodiment.
[0046] See also Figure 5As shown, the system includes a control module M2, an alarm module M3 and the suspension fracture feedback module M1 as described above.
[0047] The suspension fracture feedback module M1 is used to send a suspension fracture feedback signal to the control module M2 through the signal transmission port when the suspension fracture occurs. The control module M2 is used to control the alarm module M3 to issue a suspension fault alarm when the suspension fracture feedback signal is received. The control module M2 can also be used to issue a normal suspension prompt by itself or by controlling the alarm module M3 when the suspension fracture feedback module M1 is powered on again and no suspension fracture feedback signal is received, so as to enhance the user's judgment on the safety of the vehicle.
[0048] Here, the control module M2 can be implemented by a hardware circuit, for example, by using logic components such as amplifiers and comparators to implement a normal suspension prompt function and a suspension fault alarm function.
[0049] Alternatively, in order to improve intelligence, the control module M2 can be an on-board computing system, a body domain control system, etc. in the vehicle, which may include a software layer, an operating system, software services, a hardware layer, a processor, memory / storage, a signal receiving / output interface, a display interface, etc.
[0050] The software layer includes: operating system and software services.
[0051] Operating system: It can manage hardware resources at the hardware layer and provide public services at the software layer.
[0052] Software service: software used to realize or facilitate the interaction between users and hardware at the hardware layer, and realize the user's interactive function on the graphical interface.
[0053] The hardware layer includes: processor, memory / storage, signal receiving / output interface, and display interface.
[0054] Processor: One or more processors that communicate with memory / storage and are the functional units that interpret computer instructions and process data in the software in the computer.
[0055] Memory / storage: A computer-readable medium that stores operating instructions for executing the prompt module and prompt sound.
[0056] Signal receiving / output interface: module for signal receiving and output. The in-vehicle module sends data to the server through the communication client and can interact with data.
[0057] Display interface: Display screen used to prompt the user of current fault information.
[0058] It should be pointed out that when the control module M2 is an on-board computing system or a body domain control system in a vehicle, the control logic executed is a conventional logic design and is not protected by this patent.
[0059] As a possible implementation manner, the alarm module M3 may be at least one of a speaker, a dashboard or a multimedia screen of the vehicle.
[0060] When the alarm module M3 is a speaker, the control module M2 controls the speaker to emit an alarm sound through a digital-to-analog signal converter and an operational amplifier. Since M2 is stored as a digital signal, it needs to be converted into an analog signal required for the speaker to emit sound through a digital-to-analog signal converter.
[0061] When the alarm module M3 is a dashboard or a multimedia screen, the alarm prompt can be given to the user by displaying an alarm indicator light, an alarm subtitle, an alarm icon, etc.
[0062] Exemplarily, the suspension fracture feedback system operates as follows:
[0063] (1) The suspension is not broken, the suspension break feedback module M1 does not output a signal, the display interface of the control module M2 does not have any abnormal prompt, and the speaker does not have any abnormal prompt;
[0064] (2) Suspension fracture: the suspension fracture feedback module M1 outputs a signal, and the display interface of the control module M2 displays a screen prompt of "suspension fracture fault, please repair as soon as possible", and a voice prompt is given through the alarm module M3. At the same time, the data is sent to the server through the communication client. The customer service staff can connect to the faulty vehicle by voice to provide maintenance guidance and emergency rescue services;
[0065] (3) After the suspension is repaired and replaced, the suspension fracture feedback module M1 is powered on again (the module switch LS1 is opened and then closed to reset the three-terminal thyristor switch D2, which avoids user misoperation. At the same time, it can only be handled by professional and trained maintenance personnel to ensure safety). The suspension fracture feedback module M1 does not output any signal, and there is no abnormal prompt on the display interface or the speaker.
[0066] This embodiment can solve the vehicle safety problem that may occur when the suspension is broken and the owner cannot detect it, and improve the safety of the vehicle through the functional design of the suspension system.
[0067] The utility model also provides a vehicle, comprising the suspension fracture feedback system as mentioned above.
[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
