Description

Technical Field

[0001] This application relates to the field of vehicle performance testing technology, and in particular to a starting device and testing system. Background Technology

[0002] Before leaving the factory, vehicles must undergo testing of core components such as engine performance, transmission shift smoothness, and braking system effectiveness to ensure they meet factory requirements. The testing of these core components employs a combination of a positioning driving test bench and a low-speed braking force data collector. During the testing process, the vehicle's engine must remain running to simulate real-world driving conditions.

[0003] In related technologies, the start-up and reset control of the testing equipment relies on a pull-cord switch located outside the driver's side window. The pull-cord switch consists of a pull cord and a limit switch. One end of the pull cord is connected to a manual pull ring, and the other end passes through the protective railing of the testing station and connects to the limit switch. The limit switch is connected in series with the main circuit of the testing equipment via a wire. When the vehicle enters the positioning test bench, the driver lowers the driver's side window, reaches out, grasps the manual pull ring, and pulls the pull cord away from the vehicle. The pull cord closes the limit switch contacts, connecting the main circuit of the testing equipment, starting the equipment and initiating data acquisition. After the test is completed, the driver pulls the pull ring again, opening the limit switch contacts, cutting off the main circuit, and resetting the equipment. The driver then raises the window, and the vehicle leaves the testing station, completing a single test. This method of starting the testing equipment requires the tester to perform actions such as lowering the window, pulling the switch, performing the test, pulling the switch again, and raising the window, which is time-consuming and affects testing efficiency. Utility Model Content

[0004] The purpose of this application is to provide a starting device and a detection system, which aims to solve the technical problem that the current starting methods of detection equipment have long operation times and affect detection efficiency.

[0005] A first aspect of this application provides a starting device, the starting device comprising: An optical signal receiving module and a control circuit are provided. The optical signal receiving module is connected to the control circuit, and the control circuit is used to control the start-up circuit of the detection device to be turned on when the optical signal receiving module detects the start-up light.

[0006] In the above-described solution, the starting device provided by this disclosure includes a light signal receiving module and a control circuit. The light signal receiving module is used to receive external starting light. In use, the operator can provide starting light through an external light source or through the vehicle's high beams. After the light signal receiving module receives the starting light, the control circuit controls the starting circuit of the detection equipment to be turned on. This starting method does not require any additional operation from the detection personnel. They only need to press the start button of the external light source or turn on the vehicle's high beams to control the starting circuit of the detection equipment to be turned on. It is convenient to operate, takes little time, and increases detection efficiency.

[0007] Optionally, the control circuit includes a circuit board, a relay, and a controller. The controller is mounted on the circuit board. The optical signal receiving module is connected to the controller via a first line on the circuit board. The controller is connected to the control terminal of the relay via a second line on the circuit board. The relay is used to control the connection and disconnection of the start-up circuit. In the above scheme, when the optical signal receiving module receives the start-up light, it can feed back the information to the controller. After receiving the information, the controller controls the control terminal of the relay to connect the start-up circuit. The structure is simple and the response speed is fast.

[0008] Optionally, the control circuit further includes an amplifier circuit, which is disposed on the circuit board, and the optical signal receiving module is connected to the controller through the amplifier circuit.

[0009] In the above scheme, when the optical signal receiving module receives the start-up light, the change in the optical signal receiving module is converted into a current signal that can drive the relay through the amplification circuit, so as to ensure that the controller can accurately identify the change in the optical signal receiving module and control the start-up circuit of the detection equipment to be turned on.

[0010] Optionally, the signal receiving module includes a photoresistor.

[0011] When the photoresistor receives the start-up light, its resistance decreases. Upon receiving this change in resistance, the control circuit activates the start-up circuit of the detection device. The photoresistor responds quickly to the light, enabling the control circuit to quickly connect and increase efficiency.

[0012] Optionally, there may be multiple photoresistors, which are spaced apart and connected in parallel.

[0013] In the above scheme, the parallel connection of multiple photoresistors can reduce the overall equivalent resistance, improve the sensitivity to light, and enhance the stability and fault tolerance of the circuit, ensuring that the photoresistors can stably feed back to the controller after receiving the start-up light.

[0014] Optionally, the starting device further includes a switch and a pull cord, the pull cord being connected to the switch, the switch being used to control the connection and disconnection of the starting circuit, and the switch being used to connect the starting circuit after being triggered by the pull cord.

[0015] In the above scheme, the switch device and pull rope are used as backup starting structures for the starting device. When the optical signal receiving module and the control circuit fail to control the start circuit to be connected, the start circuit can be connected by the switch device and pull rope to ensure that the detection can be carried out smoothly and thus not affect the detection efficiency.

[0016] Optionally, a pull ring is provided at the end of the pull rope away from the switching device.

[0017] In the above solution, staff can pull the ring to move the rope, increasing the convenience of operation.

[0018] A second aspect of this application provides a detection system, comprising: The detection equipment and the starting circuit are connected to the power unit of the detection equipment and are used to start the power unit. The aforementioned starting device is connected to the starting circuit.

[0019] It should be noted that the technical effects brought about by the second aspect of this application can be referred to the technical effects brought about by the corresponding implementation of the first aspect, and will not be repeated here.

[0020] Optionally, the testing equipment includes an engine performance testing device adapted to test the engine performance of a vehicle, and the starting circuit is connected to the power unit of the engine performance testing device.

[0021] In the above solution, the engine performance testing equipment can be started by starting the starting device to test the engine performance, ensuring that the engine performance after leaving the factory meets the design requirements. At the same time, it increases the convenience of starting the engine performance testing equipment and increases the testing efficiency.

[0022] Optionally, the testing equipment includes a brake testing device adapted to test the braking performance of a vehicle, and the starting circuit is connected to the power unit of the brake testing device.

[0023] In the above solution, the braking test equipment can be started by starting the starting device to test the braking performance of the vehicle, ensuring that the braking performance of the vehicle after leaving the factory meets the design requirements. At the same time, it increases the convenience of starting the braking test equipment and increases the testing efficiency. Attached Figure Description

[0027] In the embodiments of this application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0028] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0029] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.

[0030] In the embodiments of this application, "parallel," "perpendicular," and "equal" include the described situation and situations similar to the described situation, where the range of similarity is within an acceptable deviation range, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity can also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, where the acceptable deviation range for approximate equality can be, for example, a difference between the two equals being less than or equal to 5% of either one.

[0031] like Figure 1 As shown in the illustration, this application provides a starting device 1, which includes a light signal receiving module 11 and a control circuit 12. The light signal receiving module 11 is connected to the control circuit 12, and the control circuit 12 is used to control the starting circuit 21 of the detection device 2 to be turned on when the light signal receiving module 11 detects the starting light. The light signal receiving module 11 is placed in front of the vehicle to be tested at the detection station. When the operator is sitting in the driver's seat of the vehicle, they can emit a starting light towards the light signal receiving module 11. The starting light can be emitted by an external light source, or the starting light source can be emitted by the vehicle itself. For example, after sitting in the driver's seat, the operator can emit a starting light towards the light signal receiving module 11 using an external light source such as a handheld flashlight; or, after sitting in the driver's seat, the operator can emit a starting light towards the light signal receiving module 11 by turning on the vehicle's headlights (low beam, high beam, etc.). The starting light can be a single beam, or multiple beams of light emitted continuously within a unit of time. For example, the starting beam can be two beams of light emitted continuously within 1 second to avoid the light signal receiving module 11 being falsely triggered; no limitation is imposed. The starting circuit 21 is connected to the power supply 22 through the control circuit 12. The control circuit 12 connects the starting circuit 21 and the power supply 22 to turn on the starting circuit 21, and disconnects the starting circuit 21 from the power supply 22.

[0032] The starting device 1 provided in this disclosure includes a light signal receiving module 11 and a control circuit 12. The light signal receiving module 11 is used to receive external starting light. In use, the operator can provide starting light through an external light source or through the high beam of a vehicle. After the light signal receiving module 11 receives the starting light, the control circuit 12 controls the starting circuit 21 of the detection device 2 to be turned on. This starting method does not require the detection personnel to perform any additional operations. They only need to press the start button of the external light source or turn on the high beam of the vehicle to control the starting circuit 21 of the detection device 2 to be turned on. It is convenient to operate, takes little time, and increases detection efficiency.

[0033] In some implementations, such as Figure 1 As shown, the control circuit 12 includes a circuit board, a relay 121, and a controller 122. The controller 122 is mounted on the circuit board. The optical signal receiving module 11 is connected to the controller 122 through a first line on the circuit board. The controller 122 is connected to the control terminal of the relay 121 through a second line on the circuit board. The relay 121 is used to control the connection and disconnection of the start circuit 21.

[0034] Relay 121 includes a bracket and a coil, iron core, armature, movable contact, and spring mounted on the bracket. The coil is sleeved around the outer periphery of the iron core and connected to a coil power supply 22. One end of the iron core is connected to the bracket, and the armature is connected to the bracket and spaced apart from the other end of the iron core. The spring connects the bracket and the armature and applies a spring force to the armature away from the iron core. The movable contact is mounted on the armature. Relay 121 also has normally open and normally closed contacts. The normally open contact is located on the side of the movable contact facing the iron core and is opposite to the movable contact position. The normally closed contact is located on the side of the movable contact away from the iron core and is opposite to the movable contact position. The starting circuit 21 includes a third line and a fourth line. One end of the third line is connected to one electrode of the power supply 22, and the other end is connected to the normally open contact. One end of the fourth line is connected to the movable contact, and the other end is connected to the detection device 2. The starting circuit 21 is connected to the other electrode of the power supply 22 through a fifth line.

[0035] When the optical signal receiving module 11 receives the start-up light, the controller 122 controls the coil to be energized, and the armature will move toward the armature. At this time, the active contact contacts the normally open contact and disconnects from the normally closed contact. The third line and the fourth line are connected, thereby turning on the start-up circuit 21 to provide working current to the detection device 2 through the start-up circuit 21.

[0036] When the optical signal receiving module 11 receives the start-up light again, the controller 122 controls the coil to be de-energized. The armature will move away from the armature under the action of the spring. At this time, the moving contact contacts the normally closed contact and disconnects from the normally open contact. The third line and the fourth line are disconnected, and the detection device 2 stops working, or the detection device 2 is reset.

[0037] In some examples, the detection device 2 also includes a reset circuit that connects to the power supply 22 when the active contact contacts the normally closed contact, thus resetting the detection device 2.

[0038] In this design, when the optical signal receiving module 11 receives the start-up light, it can feed the information back to the controller 122. After receiving the information, the controller 122 controls the control terminal of the relay 121 to connect the start-up circuit 21. The structure is simple and the response speed is fast.

[0039] In some implementations, reference continues. Figure 1 The control circuit 12 also includes an amplifier circuit 123, which is mounted on the circuit board. The optical signal receiving module 11 is connected to the controller 122 through the amplifier circuit 123. The amplifier circuit 123 is an electronic circuit capable of increasing the amplitude or power of an electrical signal. Essentially, the amplifier circuit 123 controls and converts energy. Utilizing the energy control characteristics of active devices (such as transistors, field-effect transistors, operational amplifiers, etc.), it controls the transfer of energy from the power supply 22 to the output signal through the input signal, making the changes in the output signal repeat or reflect the changes in the input signal.

[0040] In this design, when the optical signal receiving module 11 receives the start-up light, the amplifier circuit 123 converts the change of the optical signal receiving module 11 into a current signal that can drive the relay 121, ensuring that the controller 122 can accurately identify the change of the optical signal receiving module 11, so as to control the start-up circuit 21 of the detection device 2 to be turned on.

[0041] In some embodiments, the signal receiving module includes a photoresistor 111. The photoresistor 111 is an electronic component whose resistance changes according to variations in light intensity. When the light received by the photoresistor 111 is dim, its resistance is high; when the light received by the photoresistor 111 is bright, its resistance decreases.

[0042] In some examples, the photoresistor 111 is made of semiconductor material, and its resistance exhibits a significantly non-linear relationship with light intensity. In the absence of light, the dark resistance of the photoresistor 111 is greater than or equal to 1 MΩ, meaning it is essentially an open circuit with no current flowing through it. When an external light beam illuminates the photoresistor 111, its light resistance is less than or equal to 2 kΩ, meaning it is essentially a closed circuit, and a loop can be formed.

[0043] In this design, when the photoresistor 111 receives the start-up light, the resistance of the photoresistor 111 decreases. After the control circuit 12 receives the change in the resistance of the photoresistor 111, it controls the start-up circuit 21 of the detection device 2 to be turned on. The photoresistor 111 can respond quickly to the irradiation of the start-up light, so that the control circuit 12 can quickly connect the start-up circuit 21, increasing the working efficiency.

[0044] In other embodiments, the signal receiving module includes a photodiode. A photodiode is a semiconductor device that directly converts light signals into electrical signals based on the internal photoelectric effect. When the photodiode receives light, it converts the light signal into an electrical signal and sends it to the controller 122, which then controls the activation circuit 21 to connect based on the signal.

[0045] As can be seen, the design of the signal receiving module is not restricted and can be designed according to actual needs.

[0046] In some implementations, the controller 122 controls the relay 121 to operate when the resistance of the photoresistor 111 is less than 2 kΩ, so as to avoid the relay 121 being accidentally triggered.

[0047] In some embodiments, a shield is provided on the top of the photoresistor 111. The shield is supported on the top of the photoresistor 111 by a bracket. The angle between the plane of the shield and the horizontal plane is θ, where θ ≤ 30°.

[0048] This design ensures that the light received by the photoresistor 111 is within a certain range, preventing other light from shining on the photoresistor 111 and causing the starting device 1 to be falsely triggered, thus increasing the safety of use.

[0049] In some embodiments, there are multiple photoresistors 111, which are spaced apart and connected in parallel.

[0050] In this design, the parallel connection of multiple photoresistors 111 can reduce the overall equivalent resistance and improve the sensitivity to light. At the same time, the multiple photoresistors 111 serve as backups for each other, enhancing the stability and fault tolerance of the circuit and ensuring that the photoresistors 111 can stably feed back to the controller 122 after receiving the start-up light.

[0051] In some implementations, such as Figure 1 As shown, the starting device 1 also includes a switch device 13 and a pull rope 14. The pull rope 14 is connected to the switch device 13. The switch device 13 is used to control the connection and disconnection of the starting circuit 21. The switch device 13 is used to connect the starting circuit 21 after being triggered by the pull rope 14.

[0052] After the vehicle to be tested is moved to the testing station, the operating end of the pull rope 14 is supported by the bracket at the driver's side window. The staff opens the window and pulls the pull rope 14 to trigger the switch device, and the switch device 13 controls the start circuit 21 to connect. After the test is completed, the pull rope 14 is pulled again, the switch device 13 is turned off, and the start circuit 21 is disconnected.

[0053] In some examples, the switching device includes a rotary switch comprising a pull cord 14, a rotating shaft, and a dial, the rotating shaft and dial being rotatably mounted on the switch base. One end of the pull cord 14 is fixed to the dial, which is coaxially connected to the rotating shaft. Pulling the pull cord 14 causes the dial and rotating shaft to rotate synchronously. The switch base has a stationary contact, and a moving contact is connected to an elastic metal spring. One end of the spring is fixedly connected to the base, and the other end is located on one side of the dial and linked with the dial. The dial has a cam structure, and a spring is located inside the dial. The starting circuit 21 includes a third line and a fourth line. One end of the third line is connected to one electrode of the power supply 22, and the other end is connected to the stationary contact. One end of the fourth line is connected to the moving contact, and the other end is connected to the detection device 2. The starting circuit 21 is connected to the other electrode of the power supply 22 via a fifth line.

[0054] When the pull cord 14 is not pulled, the dial is in the initial position, and the moving contact and the stationary contact are in the open state.

[0055] When the pull cord 14 is pulled for the first time, the pull cord 14 drives the dial and the rotating shaft to rotate 90°. After the dial rotates to the position, the cam structure pushes the spring plate to move in the direction away from the dial, so that the moving contact and the stationary contact are in contact, and the starting circuit 21 is connected. At this time, the dial returns slightly under the action of its own spring, while the spring plate remains in a deformed state.

[0056] When the pull cord 14 is pulled for the first time, the dial continues to rotate 90°. The pushing force of the dial's protruding structure on the spring plate disappears, and the spring plate resets under its own elastic force. The moving contact and the stationary contact are disconnected again, and the starting circuit 21 is disconnected. At this time, the dial slightly returns to its original position under the action of its own spring.

[0057] In this design, the switch device 13 and the pull rope 14 are used as backup starting structures for the starting device 1. When the optical signal receiving module 11 and the control circuit 12 fail to control the starting circuit 21 to be turned on, the starting circuit 21 can be turned on by the switch device 13 and the pull rope 14 to ensure that the detection can be carried out smoothly and thus not affect the detection efficiency.

[0058] In some embodiments, a pull ring 141 is provided at the end of the pull cord 14 away from the switch device 13.

[0059] With this design, staff can pull the ring 141 to move the rope 14, increasing the ease of operation for staff.

[0060] This application also provides a detection system, including a detection device 2, a starting circuit 21, and the aforementioned starting device 1, wherein the starting device 1 includes all the technical features of the aforementioned starting device 1. The starting circuit 21 is connected to the power unit of the detection device 2 and is used to start the power unit, and the starting device 1 is connected to the starting circuit 21.

[0061] It should be noted that the technical effects brought about by the detection system of this application can be referred to the technical effects brought about by the corresponding implementation of the above-mentioned starting device 1, and will not be repeated here.

[0062] In some embodiments, the testing device 2 includes an engine performance testing device 2, which is adapted to test the engine performance of a vehicle, and the starting circuit 21 is connected to the power unit of the engine performance testing device 2.

[0063] In some examples, the engine performance testing equipment 2 includes a roller test bench and test components. The vehicle to be tested is driven onto the roller test bench, and the roller test bench simulates road driving, allowing the wheels of the vehicle to rotate on the rollers, thus achieving stationary driving. The test components include a dynamometer, a diagnostic instrument, an exhaust gas analyzer, a tachometer, a noise meter, and a vibration meter. The dynamometer is paired with the rollers and applies resistance to simulate the load during vehicle operation. The diagnostic instrument reads engine ECU data in real time, including parameters such as engine speed, fuel injection pulse width, and coolant temperature. ECU stands for Electronic Control Unit, which is the vehicle's electronic control unit. The exhaust gas analyzer collects and analyzes exhaust gas components to detect whether the engine combustion efficiency and emissions meet standards. The tachometer assists in verifying the engine speed to ensure consistency with ECU data. The noise meter detects noise during engine operation and vehicle operation to determine if there are any abnormalities. The vibration meter measures the vibration values ​​of the engine and vehicle body to evaluate the smoothness of operation. The starting circuit 21 is connected to the drive motor of the roller test bench and the starting circuits 21 of the dynamometer, diagnostic instrument, exhaust gas analyzer, noise meter, and vibration meter.

[0064] With this design, the engine performance testing equipment 2 can be started by starting device 1 to test the engine performance, ensuring that the engine performance after leaving the factory meets the design requirements. At the same time, it increases the convenience of starting engine performance testing equipment 2 and increases testing efficiency.

[0065] In some embodiments, the testing device 2 includes a brake testing device 2 adapted to test the braking performance of a vehicle, and the starting circuit 21 is connected to the power unit of the brake testing device 2.

[0066] In some examples, the brake testing device 2 includes a roller brake test bench and a braking force measuring device. The starting circuit 21 is connected to the drive motor of the roller brake test bench and the power supply circuit of the braking force measuring device to control the start of the drive motor. During testing, the wheels of the vehicle under test are placed between the driving and driven rollers of the roller brake test bench. The rollers drive the wheels to rotate, and the driver depresses the brake pedal. The braking force measuring device can then measure the magnitude of the braking force.

[0067] With this design, the braking test equipment 2 can be started by starting device 1 to test the braking performance of the vehicle, ensuring that the braking performance of the vehicle after leaving the factory meets the design requirements. At the same time, it increases the convenience of starting the braking test equipment 2 and increases the testing efficiency.

[0068] like Figure 2 As shown below, the braking performance testing process for the vehicle under test is explained: Step S1: Preparations before vehicle inspection.

[0069] Step S2: The vehicle to be tested enters the test location.

[0070] Step S3: Identify the vehicle information of the vehicle to be detected.

[0071] Step S4: The vehicle to be tested emits a start-up light once.

[0072] In step S5, the photoresistor receives the activation light.

[0073] Step S6: The resistance of the photoresistor decreases, thus activating the start-up circuit.

[0074] Step S7: Start the roller brake test bench.

[0075] Step S8: The operator begins the inspection work.

[0076] Step S9: The photoresistor receives the secondary start-up light emitted by the vehicle under test.

[0077] In step S10, the resistance of the photoresistor decreases, thus activating the reset circuit.

[0078] Step S11: The reset circuit is turned on to reset the roller brake test bench.

[0079] Step S12: The vehicle to be tested is moved out of the roller brake test bench.

[0080] The following is a detailed description of one implementation method for testing the braking performance of the vehicle under test: Step S1: Check the cleanliness of the roller brake test bench surface to ensure there are no debris; confirm the calibration validity period of the low-speed braking force data collector sensor. Start-up circuit 21, control circuit 12, and the switching device are all in standby mode.

[0081] Step S2: The vehicle to be tested drives into the roller brake test bench along the guide line, aligning the wheels with the rollers of the roller brake test bench (alignment deviation ≤ 5cm), tightening the handbrake, and putting the transmission into neutral.

[0082] Step S3: Start the engine and maintain idle speed (800-1000 rpm); turn on the vehicle power supply 22 and ensure the high beams illuminate normally. Use the RFID device to read the vehicle identification code and input information such as the vehicle model and engine number into the detection system. The system will then match the corresponding detection procedure.

[0083] Step S4: continuously flip the high beam switch upwards (for 0.5-1 second) until the vehicle being tested emits its starting beam for the first time.

[0084] In step S5, the photoresistor 111 receives the activation light.

[0085] In step S6, the resistance of photoresistor 111 drops below 2kΩ. The change is fed back to controller 122 by amplifier circuit 123. Controller 122 controls the open contact of solenoid valve to close, and starts circuit 21.

[0086] In step S7, the rollers on the roller brake test bench begin to rotate.

[0087] In step S8, the operator presses the brake pedal, and the low-speed braking force data collector begins to collect data such as wheel braking force and braking distance.

[0088] Step S9: continuously flip the high beam switch upwards (for 0.5-1s). The vehicle to be tested will emit the starting light for the second time, and the photoresistor 111 will receive the starting light.

[0089] In step S10, the resistance of the photoresistor 111 drops below 2kΩ. The change is fed back to the controller 122 through the amplifier circuit 123. The controller 122 controls the solenoid valve to close its open and close contacts, and the reset circuit is turned on.

[0090] In step S11, the roller brake test bench stops rotating, the data collector clears the temporary data, and the initial test state is restored.

[0091] Step S12: Start the vehicle, drive it away from the test bench along the guide line, and park it in the designated area.
