[0019] The embodiments of the utility model will be described clearly and completely in combination with the drawings. Obviously, the described embodiments are only some of the embodiments of the utility model, but not all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0020] It should be noted that the terms "first", "second", "third" in the utility model are only to distinguish similar objects, and do not represent the specific order of the objects. Understandably, "first", "second", "third" can be interchanged in specific order or sequence as allowed.

[0021] In the field of automobile industry, test benches are usually used to simulate various working conditions and environments in order to perform performance tests, reliability tests, durability tests, safety tests, etc. on the equipment and systems of the automobile, thereby helping manufacturers to evaluate the quality and reliability of the products and to improve the product design and manufacturing process.

[0022] In the related art, for the electromagnetic valve shock absorber applied to the vehicle, the current test bench only stipulates a limited number of test parameters, which cannot adapt to the rapid development of the electromagnetic valve shock absorber.

[0023] Therefore, the utility model provides a test system capable of flexibly providing matching test parameters (including test current and test voltage) for various different electromagnetic valve shock absorbers.

[0024] As shown in Figure 1 The utility model provides a test system 100 for testing an electromagnetic valve shock absorber 10. The test system 100 comprises a test support frame 110, a power supply device 120, a first input device 130, a second input device 140 and a switching switch 150.

[0025] The test support frame 110 is designed to carry the electromagnetic valve shock absorber 10 to be tested.

[0026] The power supply device 120 is designed to provide variable voltage and variable current, and the power supply device 120 is electrically connected with the electromagnetic valve shock absorber 10, especially with the electromagnetic valve thereof. Thus, the electromagnetic valve shock absorber 10, especially the electromagnetic valve thereof, can be powered to provide the required test voltage and test current.

[0027] The first input device 130 and the second input device 140 are independent of each other. The first input device 130 is designed to receive a first user instruction indicating a target voltage (or test voltage) and a target current (or test current), and the second input device 140 is designed to receive a second user instruction indicating a target voltage (or test voltage) and a target current (or test current). By providing two input devices independent of each other, the user can conveniently set the test voltage and the test current.

[0028] For example, the first input device 130 can be arranged at the test support frame 110, and the second input device 140 can be arranged away from the test support frame 110. Thus, when the user is located next to the test support frame 110, the user can set the test voltage and the test current through the first input device 130, and when the user is away from the test support frame 110, the user can set the test voltage and the test current remotely, for example, through the second input device 140.

[0029] The switching switch 150 is designed to switch between a first input state and a second input state. In the first input state, the switching switch 150 communicatively connects the first input device 130 with the power supply device 120, so as to transmit the first user instruction to the power supply device 120. In the second input state, the switching switch 150 communicatively connects the second input device 140 with the power supply device 120, so as to transmit the second user instruction to the power supply device 120. Thus, the user can determine whether to input the user instruction through the first input device 130 or the second input device 140 by operating the switching switch 150.

[0030] Correspondingly, the power supply device 120 is also designed to provide the target voltage and the target current for the electromagnetic valve damper 10, especially for the electromagnetic valve thereof, based on the received first user instruction or second user instruction.

[0031] Therefore, the test system 100 provided by the embodiments of the present application can flexibly and conveniently set the corresponding target voltage and target current for various test scenarios, without the need to specially design and replace the appropriate power supply device for different types of electromagnetic valve dampers or for different test scenarios, thereby reducing the cost of the test system 100 for testing the electromagnetic valve damper and improving the test efficiency.

[0032] In some embodiments, as Figure 1 and Figure 2As shown, the power supply device 120 comprises a controller (e.g. a programmable logic controller, PLC) 121 and a power supply (e.g. a stabilized power supply) 122 with adjustable voltage and adjustable current. The controller 121 is communicatively, e.g. electrically, connected with the switching switch 150 on the one hand and with the power supply 122 on the other hand, and the controller 121 is designed to control the power supply 122 to output a corresponding voltage and current. In one example, the power supply 122 can comprise an adjustable resistor (e.g. a potentiometer) and a direct current voltage source (e.g. a 12V direct current voltage source) in order to provide an adjustable voltage and an adjustable current. In one example, the controller 121 is communicatively connected with the power supply 122 by a Modbus protocol. However, the utility model is not limited thereto, and the controller 121 can also be communicatively connected with the power supply 122 by other communication protocols.

[0033] Here, the switching switch 150 electrically connects the first input device 130 or the second input device 140 with the controller 121 and the power supply 122. That is, the switching switch 150 communicatively connects the first input device 130 with the controller 121 in the first input state in order to transmit the first user instruction to the controller 121, so that the controller 121 controls the power supply 122 to provide a target voltage and a target current indicated by the first user instruction based on the first user instruction, e.g. transmits the first user instruction or the target voltage and the target current indicated by the first user instruction to the power supply 122 by a Modbus protocol. The switching switch 150 communicatively connects the second input device 140 with the controller 121 in the second input state in order to transmit the second user instruction to the controller 121, so that the controller 121 controls the power supply 122 to provide a target voltage and a target current indicated by the second user instruction based on the second user instruction, e.g. transmits the second user instruction or the target voltage and the target current indicated by the second user instruction to the power supply 122 by a Modbus protocol.

[0034] In some embodiments, as Figure 3 As shown, the first input device 130 can comprise a voltage input knob (i.e. a physical knob) 131 for setting a target voltage and a current input knob (i.e. a physical knob) 132 for setting a target current. Further, at least one of the voltage input knob 131 and the current input knob 132 can be designed as a stepless adjustable knob, preferably both the voltage input knob 131 and the current input knob 132 are designed as stepless adjustable knobs.

[0035] In some embodiments, as Figure 4 As shown, the second input device 140 can comprise a display screen for receiving the second user instruction via a user interface. The display screen is in particular a touch screen for realizing human-computer interaction and displaying in a graphic and textual manner on the user interface.

[0036] like Figure 4 As shown, the user interface includes a first control 141 for setting the target voltage and a second control 142 for setting the target current.

[0037] As some implementations, at least one of the first control 141 and the second control 142 can be designed as an input box. In particular, both the first control 141 and the second control 142 are designed as input boxes.

[0038] As some other implementations, at least one of the first control 141 and the second control 142 can be designed as a menu, for example, both the first control 141 and the second control 142 can be designed as menus.

[0039] In some embodiments, such as Figure 4 As shown, the user interface can also include multiple third controls 143a, 143b, and 143c for setting different fixed target currents. These third controls are designed as virtual buttons, for example. In other words, each third control is associated with a fixed target current and an optional target voltage, and the user can quickly set the target current and target voltage by operating the third control, for example, by clicking the virtual button that serves as the third control. For example, operating the third control 143a can quickly set the target current to 0A, operating the third control 143b can quickly set the target current to 0.8A, and operating the third control 143c can quickly set the target current to 1.6A.

[0040] This is particularly advantageous in common testing scenarios for various types of solenoid valves and shock absorbers, as users do not need to troublesome input of the test parameters required for common testing scenarios.

[0041] It is understood here that the target current and optional target voltage associated with each third control can be customized.

[0042] In some embodiments, the user interface may also be designed to, when the switch is in a first input state, acquire a first user instruction and display the target voltage indicated by the first user instruction in a first control and the target current indicated by the first user instruction in a second control.

[0043] For example, such as Figure 2 As shown, when the switch is in the first input state, the controller 121 acquires the first user instruction. At this time, the controller 121 can transmit the first user instruction to the display interface of the second input device 140, or the display interface of the second input device 140 can actively read the first user instruction from the controller 121. Then, the display interface displays the target voltage indicated by the first user instruction in the first control and the target current indicated by the first user instruction in the second control.

[0044] In some embodiments, the user interface may also be designed to display the input status of the toggle switch.

[0045] For example, such as Figure 4 As shown, the user interface also includes a display control 144 for the input state of the switch. The user interface of the display screen reads the input state of the switch 150 from the controller 121, which is electrically connected to the switch 150, and displays the input state of the switch 150 in the display control 144.

[0046] In some embodiments, such as Figure 3 As shown, the switch 150 can be designed as a toggle knob, that is, a physical knob for switching the switch 150 to a first input state or a second input state.

[0047] In other embodiments, the toggle switch 150 may also be designed as a virtual button set in the display interface of the second user equipment 140.

[0048] In some other embodiments, the switch 150 may also include a physical knob for switching the switch 150 to a first input state or a second input state and a virtual button set in the display interface of the second user equipment 140.

[0049] In some embodiments, the test system 100 may further include voltage and current sensors (not shown), arranged on a circuit electrically connected to the power supply device 120 and the solenoid valve damper 10, to detect the actual voltage and actual current supplied to the solenoid valve damper. Here, a user interface is also designed to acquire and display the actual voltage and actual current.

[0050] For example, such as Figure 4 As shown, the user interface can also include a display control 145 for displaying the actual voltage and a display control 146 for displaying the actual current. The controller 121 uses a voltage sensor and a current sensor to acquire the actual voltage and actual current. The controller 121 can then transmit the acquired actual voltage and actual current to the display interface of the second input device 140, or the display interface of the second input device 140 can actively read the actual voltage and actual current from the controller 121. The display interface then displays the actual voltage in display control 145 and the actual current in display control 146.

[0051] In some embodiments, such as Figure 3As shown, the test system 100 may further include a start button 160, a stop button 170, and an emergency stop button 180. The start button 160 is used to start the test. For example, only after operating the start button 160 can the power supply device 120 provide the corresponding target voltage and target current to the solenoid valve damper 10. The stop button 170 is used to stop the test. For example, only after operating the stop button 170 can the power supply device 120 stop supplying voltage and current. The emergency stop button 180 is used to disconnect the test system 100 to ensure safety by cutting off power and stopping the system in case of a malfunction.

[0052] In some embodiments, the test system 100 may further include a switching power supply (not shown) for powering the control circuit of the test system 100, such as powering the controller 121, the first input device 130, the second input device 140, the switch 150, etc.

[0053] The exemplary usage process of the test system 100 according to this utility model is described below.

[0054] According to an exemplary usage flow, use Figure 3 The first input device 130, as shown, inputs a first user command, specifically as follows: Switching the toggle switch 150 to the first input state, for example, by operating the physical knob that serves as the toggle switch 150 and rotating it to the first input state; then connecting the solenoid valve damper 10 to the test system 100; operating the voltage input knob 131 and the current input knob 132, rotating them to the desired target voltage and target current; Figure 4 The set target voltage and target current are displayed on the second input device 140 shown. Observe whether the set target voltage and target current are correct. Operate the start button 160, and the power supply device 120 outputs the target voltage and target current to the solenoid valve damper 10 based on the first user command. Figure 4 The actual voltage and actual current are displayed on the second input device 140. After the test is completed, the stop button 170 is operated. When the actual voltage and actual current displayed on the second input device 140 are zero, the solenoid valve damper 10 is disconnected from the test system 100.

[0055] Following another exemplary usage flow, use Figure 4The second input device 140 shown inputs the second user instruction, specifically as follows: switch the switch 150 to the second input state, for example, operate the physical knob as the switch 150, and rotate it to the second input state; then connect the electromagnetic valve damper 10 with the test system 100; input the target voltage in the first control 141 of the display interface of the second input device, input the target current in the second control 142, or directly operate the third control 143; observe whether the set target voltage and target current are correct; operate the start button 160, and the power supply device 120 outputs the target voltage and target current to the electromagnetic valve damper 10 based on the second user instruction; in Figure 4 The actual voltage and actual current are displayed on the second input device 140 shown; after the test is completed, operate the stop button 170, and when the actual voltage and actual current displayed on the second input device 140 are zero, disconnect the electromagnetic valve damper 10 with the test system 100.
