[0056] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0057] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments, and the well-known modules, units and their connections, links, communications or operations are not shown or described in detail. In addition, the described features, architectures or functions can be combined in any way in one or more embodiments. It should be understood by those skilled in the art that the various embodiments described below are only for illustration and are not intended to limit the scope of protection of the present invention. It can also be easily understood that the modules or units or processing methods in the various embodiments described herein and shown in the drawings can be combined and designed according to various different configurations. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0058] The definitions of various nouns or methods in the following embodiments, except for those that are logically untenable, are generally based on the broad concepts that can be implemented under the premise of the disclosure in the embodiments. Under such an understanding, the various specific subordinate specific definitions of the nouns or methods should be regarded as the utility model content of the utility model, and should not be narrowly understood or biasedly interpreted on the grounds that the specification does not disclose such specific definitions. Similarly, under the premise that it can be logically implemented, the order of the steps in the method is flexible and changeable, and the specific subordinate specific definitions of the broad concepts of various nouns or methods are all within the scope of protection of the utility model.

[0059] The main solution of the embodiment of the present application is: connecting the driving component to the cab to be tested to drive the cab to be tested to move, and then connecting the first end of the switch component to the power supply end, and the second end of the delay switch component is electrically connected to the driving component, so that the delay switch component sets a corresponding preset time length when triggered by the user, and is in a closed state within the preset time length when its controlled end receives a control signal to open the path between the power supply end and the driving component, thereby driving the cab to be tested to move.

[0060] Because the existing technology in the existing test scheme of the automatic driving cab rollover test mainly relies on photoelectric sensors to detect the position of the cab to be tested, it is relatively passive and has certain limitations in the precise control of the cab rollover.

[0061] This application provides a solution to achieve action time control of the cabs to be tested of different vehicle models to meet the test requirements of different vehicle models.

[0062] It should be understood that in the existing scheme of using photoelectric sensors to detect the position of the cab to be tested and then triggering the driving operation of the cab to be tested, in actual operation, the photoelectric sensor only has two signals, on and off, so that the movement angle of the cab to be tested is only 26°, and the movement angle cannot be adjusted according to actual needs. Therefore, there are obvious limitations in the control of driving the movement of the cab to be tested.

[0063] Based on the above problems, refer to Figure 1 In one embodiment of the present invention, the cab testing device includes a driving assembly 100 and a delay switch assembly 200, wherein:

[0064] The driving assembly 100 is connected to the cab 300 to be tested; the driving assembly 100 is used to drive the cab 300 to be tested to move; the first end of the delay switch assembly 200 is connected to the power supply 400 end, and the second end of the delay switch assembly 200 is electrically connected to the driving assembly 100.

[0065] In this embodiment, the drive assembly 100 may be a system consisting of multiple electric motors and corresponding transmission mechanisms. These electric motors and transmission mechanisms can precisely control the cab 300 under test to perform movements such as raising or lowering. The drive assembly 100 can be connected to a tilting hydraulic cylinder 700 to perform the corresponding raising or lowering movement of the cab 300 under test, ensuring that the cab 300 under test can stably and accurately follow a pre-set trajectory during testing.

[0066] In this embodiment, the delay switch assembly 200, as an important control module, has a first end connected to the power supply 400 and a second end electrically connected to the drive assembly 100. This connects the power supply 400 to the power supply 400 of the drive assembly 100 within a preset time, thereby powering the drive assembly 100 and ensuring a stable power supply to the drive assembly 100 during the test. By controlling the on and off state of the delay switch assembly 200, the state of the path between the power supply 400 and the drive assembly 100 can be controlled, thereby achieving control over the movement of the cab 300 under test.

[0067] Among them, the delay switch component 200 is used to set a corresponding preset time length when triggered by the user; the delay switch component 200 is used to be in a closed state within the preset time length when its controlled end receives a control signal to conduct the path between the power supply 400 end and the driving component 100.

[0068] In this embodiment, the delay switch assembly 200 has a preset time length setting function. When the delay switch assembly 200 is triggered by the user, it will enter a closed state within the preset time length. At this time, the path between the power supply 400 and the drive assembly 100 is connected, and the drive assembly 100 starts working, driving the cab 300 to be tested to perform corresponding actions. When the delay time length is reached, the delay switch assembly 200 automatically disconnects, the drive assembly 100 stops working, and the cab 300 to be tested stops moving. The method of precisely controlling the movement of the cab 300 to be tested by the delay switch assembly 200 is more proactive and accurate than the traditional photoelectric sensor detection method. By setting different delay time lengths, the misuse conditions of different users can be simulated, thereby better evaluating the performance of the cab 300 to be tested in actual use.

[0069] In this embodiment, the preset duration of the delay switch assembly 200 can be flexibly set according to different vehicle models and different test requirements, for example, it can be set to 1 second, 2 seconds, 5 seconds or longer. For example, a full-angle rollover test for a Type A vehicle may require a longer rollover time. In this case, the preset duration of the delay switch assembly 200 can be set to 10 seconds; while a partial-angle rollover test for a Type B vehicle may only require a shorter rollover time. In this case, the preset duration of the delay switch assembly 200 can be calculated based on the rollover angle, for example, set to 3 seconds. This flexible setting method enables the present cab test device to adapt to various vehicle models and test requirements, improving the versatility and flexibility of the test. In addition, the delay switch assembly 200 can also be set with multiple preset durations to meet the test requirements of different vehicle models or to meet the needs of the same vehicle model to roll over at different angles.

[0070] Optionally, refer to Figure 2 and Figure 3Another embodiment of the present invention provides a cab testing device, based on the above Figure 1 In the illustrated embodiment, the preset duration includes a preset first duration and a preset second duration.

[0071] In this embodiment, by subdividing the preset time length into a preset first time length and a preset second time length, the corresponding time length is set according to the requirements of the flipping direction. This setting allows the testing process to be closer to the actual user's misuse conditions, and thus more accurately evaluate the performance of the cab 300 to be tested.

[0072] Please refer to Figure 2 As shown, the drive assembly 100 includes a forward drive assembly 110 and / or a reverse drive assembly 120 .

[0073] In this embodiment, the forward drive assembly 110 and / or the reverse drive assembly 120 are designed to provide the cab testing device with more functionality and flexibility. The forward drive assembly 110 is used to trigger the cab 300 to be tested to flip forward according to a preset trajectory, while the reverse drive assembly 120 is used to trigger the cab 300 to be tested to flip in the opposite direction when needed. The output end of the drive assembly 100 is connected to an operating motor, which can realize forward rotation or reverse rotation as needed under the control of the forward drive assembly 110 or the reverse drive assembly 120, thereby generating a control signal that triggers the forward flip or reverse flip of the cab 300 to be tested.

[0074] It is understandable that the speed of the operating motor can be adjusted by adjusting the current input to the operating motor, and then the forward drive component 110 drives the operating motor forward or the reverse drive component 120 drives the operating motor reverse, and combined with the preset first time length and the preset second time length, the timing and speed of the flipping of the cab 300 to be tested can be accurately controlled. By varying the length of the delay, the flip angle of the cab 300 to be tested can be controlled to meet the requirements of different vehicle models and test needs. This design with a forward drive component 110 and a reverse drive component 120 allows the user to freely choose to trigger a separate forward test, a separate reverse test, or a combined forward and reverse test when needed, and can better perform a flip simulation based on the user's different operating habits or test needs.

[0075] Individual forward and reverse rotation tests can be manually controlled by the user, while combined forward and reverse rotation testing can be controlled manually or automatically by the controller included in the cab test device. This automatically switches between forward and reverse rotation, simulating the complex operating conditions that may occur in actual use. In this way, the cab test device provides a more comprehensive testing environment, helping developers more accurately evaluate the performance and reliability of the cab 300 under various operating conditions.

[0076] Please refer to Figure 2 As shown, in one embodiment, the time delay switch assembly 200 includes a first time delay relay 210, wherein:

[0077] The first delay relay 210 is used to set a corresponding preset first time length when triggered by the user. The first delay relay 210 is used to be in a closed state within the preset first time length when its controlled end receives a control signal to open the path between the power supply 400 end and the forward drive component 110.

[0078] In this embodiment, the first time delay relay 210 can be set to a specific preset first duration, which corresponds to the waiting time required to trigger the forward flip of the cab 300 under test. When the first time delay relay 210 is triggered, it enters a closed state within the preset first duration. At this time, the path between the power supply 400 and the forward drive assembly 110 is connected, and the forward drive assembly 110 begins to operate, triggering the cab 300 under test to flip forward along a preset trajectory after the countdown for the preset first duration ends. In this way, the starting delay of a cab flip under normal user operation can be accurately simulated.

[0079] like Figure 3 As shown, in another embodiment, the time delay switch assembly 200 includes a second time delay relay 220, wherein:

[0080] The second delay relay 220 is used to set a corresponding preset second time length when triggered by the user. The second delay relay 220 is used to be in a closed state within the preset second time length when its controlled end receives a control signal to open the path between the power supply 400 end and the reversing drive component 120.

[0081] In this embodiment, the second delay relay 220 can be set to a specific preset second duration, which corresponds to the waiting time required to trigger the reverse flip of the cab 300 under test. When the second delay relay 220 is triggered, it will enter a closed state within the preset second duration. At this time, the path between the power supply 400 and the reversing drive component 120 is connected, and the reversing drive component 120 begins to operate to trigger the cab 300 under test to reverse flip along a preset trajectory after the countdown of the preset second duration ends. This design enables the test device to simulate scenarios where the cab needs to quickly reverse due to user misoperation or in an emergency.

[0082] In this embodiment, the delay time of the first delay relay 210 or the second delay relay 220 is changed by adjusting the adjustment component of the first delay relay 210 or the second delay relay 220, such as rotating the adjustment screw, so that the user can set different delay durations according to actual needs to adapt to different vehicle models and testing requirements.

[0083] like Figure 2 and Figure 3 As shown, in another embodiment, the time delay switch assembly 200 includes a first time delay relay 210 and a second time delay relay 220, wherein:

[0084] The first time delay relay 210 is configured to set a corresponding preset first time length when triggered by a user. The first time delay relay 210 is configured to be in a closed state for the preset first time length when a controlled end thereof receives a control signal to open a path between the power supply 400 and the forward drive assembly 110.

[0085] The second delay relay 220 is used to set a corresponding preset second time length when triggered by the user. The second delay relay 220 is used to be in a closed state within the preset second time length when its controlled end receives a control signal to open the path between the power supply 400 end and the reversing drive component 120.

[0086] In this embodiment, by providing both a first time delay relay 210 and a second time delay relay 220, the test device can flexibly simulate user demands for cab rollover under different operating conditions. Based on actual testing requirements, the user can choose to use only the first time delay relay 210 for forward rollover testing, or only the second time delay relay 220 for reverse rollover testing. Alternatively, the user can use both time delay relays simultaneously, alternating forward and reverse rollover simulations during testing, to comprehensively evaluate the performance and reliability of the cab 300 under various operating modes.

[0087] Furthermore, the time delay switch assembly 200 of this embodiment can also include logic control functionality, allowing the user to customize the triggering sequence and conditions for the time delay relays. For example, the user can configure the first time delay relay 210 to automatically trigger the second time delay relay 220 after a preset first duration, thereby enabling continuous forward and reverse flipping testing.

[0088] Optionally, refer to Figure 4 Another embodiment of the present invention provides a cab testing device, based on the above Figure 2 and Figure 3 In the illustrated embodiment, the time delay switch assembly 200 includes a first control assembly 230, wherein:

[0089] A first output end of the first control component 230 is connected to the controlled end of the first time delay relay 210 , and a second output end of the first control component 230 is connected to the controlled end of the second time delay relay 220 .

[0090] In this embodiment, the first control component 230 can be implemented by a main controller, such as an MCU (Microcontroller Unit), a DSP (Digital Signal Process), an FPGA (Field Programmable Gate Array), a SOC (System On Chip), etc.

[0091] In this embodiment, the first control component 230 is electrically connected to the first delay relay 210 and the second delay relay 220 respectively, and can control the switching states of the first delay relay 210 and the second delay relay 220 respectively, thereby controlling the working states of the forward drive component 110 and the reverse drive component 120 to realize forward and reverse flipping tests of the cab, thereby improving the degree of automation of the test and increasing the flexibility and accuracy of the test.

[0092] Furthermore, the first control component 230 can control the triggering timing and duration of the first delay relay 210 and the second delay relay 220 according to a preset test process or user-defined test requirements. For example, in the first phase of testing, the first control component 230 may trigger only the first delay relay 210 to simulate a forward rollover of the cab; in the second phase of testing, the first control component 230 may trigger only the second delay relay 220 to simulate a reverse rollover of the cab; in more complex test scenarios, the first control component 230 may also alternately trigger the two delay relays to simulate the continuous rollover or rapid switching of the cab's rollover direction that may occur in actual use, making the test more realistic and improving the reliability and effectiveness of the test.

[0093] Please refer to Figure 4 and Figure 11 As shown, in this embodiment, the cab testing device further includes a rollover position detection component 500, wherein:

[0094] The output end of the flip position detection component 500 is connected to the input end of the first control component 230. The flip position detection component 500 is used to detect whether the flip position is vertical or horizontal to generate a corresponding flip signal; the first control component 230 is used to output a corresponding control signal according to the flip signal to control the first delay relay 210 or the second delay relay 220 to close.

[0095] In this embodiment, the flip position detection assembly 500 can be a sensor capable of detecting the driving position of the forward drive assembly 110 or the reverse drive assembly 120, such as an angle sensor, a position switch, or a mechanical lever. If it is a mechanical lever, the mechanical lever includes a movable lever and at least two fixed levers. One end of the movable lever is connected to the motor shaft of the operating motor at the end of the drive assembly 100 to achieve rotation under the drive of the operating motor. During the rotation, the movable lever contacts at least one fixed lever to achieve electrical connection, thereby triggering a corresponding position signal to determine the position (such as vertical or horizontal position) of the cab 300 to be flipped to achieve autonomous testing. This design not only improves the degree of automation of the test, but also reduces the errors that may be caused by human operation, thereby improving the reliability and effectiveness of the test.

[0096] Optionally, refer to Figure 11 Another embodiment of the present invention provides a cab testing device, based on the above Figure 4 In the illustrated embodiment, the flip position detection assembly 500 includes a movable lever 510, a first fixed lever 520, and a second fixed lever 530, wherein:

[0097] The movable lever 510 is connected to the negative pole of the power supply 400; the first fixed lever 520 is electrically connected to the movable lever 510, and the first fixed lever 520 is used to output a horizontal flip signal to the first control component 230 when electrically connected to the movable lever 510; the second fixed lever 530 is electrically connected to the movable lever 510, and the second fixed lever 530 is used to output a vertical flip signal to the first control component 230 when electrically connected to the movable lever 510.

[0098] In this embodiment, the movable lever 510, the first fixed lever 520, and the second fixed lever 530 together constitute a simple mechanical flip position detection assembly 500. The movable lever 510 rotates by operating the motor. Its design allows it to contact the first fixed lever 520 or the second fixed lever 530 at a specific angle or position, thereby achieving electrical connection between the movable lever 510 and the first fixed lever 520, or between the movable lever 510 and the second fixed lever 530.

[0099] It should be understood that when the movable lever 510 rotates to contact the first fixed lever 520, a closed circuit is formed between the two. At this time, the first fixed lever 520 will send a horizontal flip signal to the first control component 230, indicating that the cab 300 under test is now in a vertical position and needs to be flipped to a horizontal position. Similarly, when the movable lever 510 contacts the second fixed lever 530, a vertical flip signal will be sent to the first control component 230, indicating that the cab 300 under test is now in a horizontal position and needs to be flipped to a vertical position. This mechanical flip position detection component 500 has the advantages of simple structure, high reliability, and low cost. Triggering the flip signal through contact between the movable lever 510 and the fixed lever avoids the errors and failures that may be caused by complex electronic sensing systems, thereby improving the stability and reliability of the system.

[0100] Optionally, refer to Figure 5 Another embodiment of the present invention provides a cab testing device, based on the above Figure 4 In the illustrated embodiment, the time delay switch assembly 200 includes a first display assembly 240, wherein:

[0101] The input end of the first display component 240 is connected to the output end of the first control component 230. The first display component 240 is used to perform a countdown action according to the preset first duration or the preset second duration when the first delay relay 210 or the second delay relay 220 is triggered.

[0102] In this embodiment, the first display component 240 can be a digital or analog display screen, and the first display component 240 is capable of displaying the remaining countdown time based on the output signal of the first control component 230. When the first delay relay 210 or the second delay relay 220 is triggered, the first display component 240 will begin counting down according to the preset first duration or the preset second duration, and will provide a corresponding prompt or signal when the countdown ends. This design allows testers to intuitively understand the remaining time of the current test phase, thereby better controlling the test progress and improving test flexibility and accuracy.

[0103] In addition, the first display component 240 can also have multiple display modes, such as countdown mode, forward timing mode, time pause / resume, etc., to meet the needs of different testing scenarios. For example, during the test process, if the test needs to be paused to make certain adjustments or observations, the tester can pause the test process to simultaneously pause the countdown, and then resume the countdown after the adjustments are completed. This flexible operation method can further improve the convenience and efficiency of testing.

[0104] Optionally, refer to Figure 11 Another embodiment of the present invention provides a cab testing device, based on the above Figure 4 In the illustrated embodiment, the first control assembly 230 includes a first trigger assembly 231, wherein:

[0105] The first end of the first trigger component 231 is connected to the negative pole of the power supply 400, and the second end of the first trigger component 231 is connected to the input end of the delay switch component 200. The first trigger component 231 is used to trigger the control signal to make the delay switch component 200 in a closed state within a preset time length to open the path between the power supply 400 end and the driving component 100.

[0106] In this embodiment, the first trigger assembly 231 can be a mechanical rebound button switch or an electronic trigger switch, which has the function of quickly closing and outputting a control signal when subjected to a certain external force or signal input. This mechanical or electronic switch design allows the tester to simply operate the first trigger assembly 231 to control the closing of the delay switch assembly 200 when triggering the rollover action, thereby controlling the drive assembly 100 to perform the rollover operation. This simplifies the operation process of the cab rollover test, improves test efficiency, ensures safety during the test, and reduces the potential risks caused by human error.

[0107] Optionally, refer to Figure 6 Another embodiment of the present invention provides a cab testing device, based on the above Figure 4 In the embodiment shown, the cab test device further includes a counter 600, wherein:

[0108] The signal input end of the counter 600 is connected to the output end of the first control component 230 . The counter 600 is used to perform a counting action according to the flip signal output by the flip position detection component 500 .

[0109] In this embodiment, the counter 600 can be an electronic counter 600 or a mechanical counter 600. The flip signal includes a vertical flip signal and a horizontal flip signal. The counter is designed to receive the vertical flip signal from the flip position detection component 500 and perform a counting action when the vertical flip signal is received. The main function of the counter 600 is to record the number of complete flips of the cab during the test, with one horizontal flip and one vertical flip being counted as a complete flip, and the vertical flip signal being used as the identification point. This design allows testers to intuitively understand the number of flips of the cab during the test, thereby better evaluating the durability and reliability of the cab test device.

[0110] The counter 600 also features data storage and export capabilities, allowing testers to analyze and process data after testing. For example, testers can export data from the counter 600 to a computer or mobile device and analyze it using professional data analysis software. This provides insight into the performance and potential issues of the cab test system.

[0111] Optionally, refer to Figure 7 、 Figure 8 as well as Figures 11 to 13 Another embodiment of the present invention provides a cab testing device, wherein the preset time length includes a preset third time length and a preset fourth time length.

[0112] Please refer to Figure 7 In one embodiment, based on the above Figure 1 In the illustrated embodiment, the drive assembly 100 includes an ascending drive assembly 130 and a descending drive assembly 140 ; ​​the ascending drive assembly 130 is used to drive the cab 300 to be tested to ascend, and the descending drive assembly 140 is used to drive the cab 300 to be tested to descend.

[0113] In this embodiment, the raising drive assembly 130 and the lowering drive assembly 140 can be connected to the oil pump motor on the cab 300 under test. The oil pump motor is used to drive the tilting hydraulic cylinder 700 on the cab 300 under test. The tilting hydraulic cylinder 700 is used to lift or lower the cab 300 under test. The preset third duration can control the time that the raising drive assembly 130 drives the cab 300 under test to rise, while the preset fourth duration controls the time that the lowering drive assembly 140 drives the cab 300 under test to lower. By setting different preset durations, the raising and lowering speeds of the cab 300 under test can be precisely controlled, ensuring that the cab 300 under test can smoothly and accurately complete the tilting action during the test, thereby improving the accuracy of the test, reducing damage to the cab due to improper operation, and improving the safety and reliability of the test.

[0114] In this embodiment, since there are an ascending drive component 130 and a descending drive component 140, the user can freely choose to trigger the cab ascending test, the cab descending test or a combined ascending and descending test when needed, and can better perform a cab flipping simulation according to the user's different operating habits or test requirements.

[0115] Individual ascending and descending tests can be manually controlled by the user, while combined ascending and descending tests can be controlled manually or automatically by the controller included in the cab test device. This automatically switches between ascending and descending, simulating the complex operating conditions that may occur in actual use. In this way, the cab test device provides a more comprehensive testing environment, helping developers more accurately evaluate the performance and reliability of the cab 300 under various operating conditions.

[0116] Reference Figure 7 As shown, in one embodiment, based on the above Figure 1 In the illustrated embodiment, the time delay switch assembly 200 includes a third time delay relay 250, wherein:

[0117] The third delay relay 250 is used to be set to be in a closed state for a corresponding preset third time period when triggered by the user to connect the path between the power supply 400 end and the rising drive component 130.

[0118] In this embodiment, the third delay relay 250 can be a mechanical delay relay that can mechanically adjust the preset time length, or it can be an electronic delay relay that receives an external signal input and sets the preset time length. When the tester needs to perform a rising test, he only needs to trigger the third delay relay 250, and the relay will remain in a closed state within the preset third time length, thereby connecting the path between the power supply 400 end and the rising drive assembly 130, so that the oil pump motor drives the flip hydraulic cylinder 700 to lift the cab 300 to be tested. This design not only simplifies the test process and improves the test efficiency, but also ensures the safety and accuracy during the test. By setting a precise third time length, it can be ensured that the cab 300 to be tested is limited in the rising distance during the test, avoiding the problem of damage to the cab due to excessive flipping.

[0119] Reference Figure 8 As shown, in one embodiment, based on the above Figure 1 In the illustrated embodiment, the time delay switch assembly 200 includes a fourth time delay relay 260, wherein:

[0120] The fourth delay relay 260 is used to be set to be in a closed state for a corresponding preset fourth time period when triggered by the user to connect the power supply 400 end and the descending drive component 140.

[0121] In this embodiment, the fourth delay relay 260 can be similar to the third delay relay 250 and can also be a mechanical or electronic delay relay. Its function is to, when triggered by the user, remain in a closed state for a predetermined fourth duration, thereby energizing the circuit between the power supply 400 and the descent drive assembly 140. When a tester needs to perform a descent test, they can do so by triggering the fourth delay relay 260. Once triggered, the fourth delay relay 260 remains closed for a predetermined fourth duration, energizing the circuit between the power supply 400 and the descent drive assembly 140. This allows the oil pump motor to drive the tilting hydraulic cylinder 700, thereby ensuring a smooth descent of the cab 300 under test. By precisely setting the fourth duration, the cab 300 under test can be accurately lowered to the designated position during the test, avoiding testing errors that could result from an incomplete landing or damage to the cab that could result from an over-descent.

[0122] Reference Figure 7 and Figure 8 As shown, in one embodiment, based on the above Figure 1 In the illustrated embodiment, the time delay switch assembly 200 includes a third time delay relay 250 and a fourth time delay relay 260, wherein:

[0123] The third delay relay 250 is used to be set to be in a closed state within a corresponding preset third time period when triggered by the user to conduct the path between the power supply 400 end and the ascending drive component 130; the fourth delay relay 260 is used to be set to be in a closed state within a corresponding preset fourth time period when triggered by the user to conduct the path between the power supply 400 end and the descending drive component 140.

[0124] In this embodiment, by combining the third delay relay 250 and the fourth delay relay 260, more flexible and diverse testing operations can be achieved. Depending on the test requirements, the tester can trigger the third delay relay 250 alone for an ascending test, or the fourth delay relay 260 alone for a descending test. Alternatively, both delay relays can be triggered simultaneously to achieve a comprehensive test with both ascending and descending operations performed continuously. This design not only increases the flexibility and diversity of testing but also better simulates the complex operating conditions encountered in actual use, allowing for a more comprehensive assessment of the performance and reliability of the cab 300 under different operating conditions. It also effectively reduces damage to the cab caused by improper operation.

[0125] Please refer to Figure 2 、 Figure 3 、 Figure 7 as well as Figure 8 As shown, in one embodiment, based on the above Figure 2 and Figure 3 In the illustrated embodiment, the preset durations include a first preset duration, a second preset duration, a third preset duration, and a fourth preset duration. The drive assembly includes a forward drive assembly 110, a reverse drive assembly 120, an ascending drive assembly 130, and a descending drive assembly 140. The time delay switch assembly includes a first time delay relay 210, a second time delay relay 220, a third time delay relay 250, and a fourth time delay relay 260.

[0126] The ascending drive assembly 130 is used to drive the cab 300 under test to ascend, and the descending drive assembly 140 is used to drive the cab 300 under test to descend. A first time delay relay 210 is configured to be set to a preset first duration when triggered by a user. Upon receiving a control signal at its controlled end, the first time delay relay 210 is configured to remain closed for the preset first duration to connect the power supply to the forward drive assembly 110. A second time delay relay 220 is configured to be set to a preset second duration when triggered by a user. Upon receiving a control signal at its controlled end, the second time delay relay 220 is configured to remain closed for the preset second duration to connect the power supply to the reverse drive assembly 120. A third time delay relay 250 is configured to be set to be closed for a preset third duration to connect the power supply to the ascending drive assembly 130 when triggered by a user. A fourth time delay relay 260 is configured to be set to be closed for a preset fourth duration to connect the power supply to the descending drive assembly 140 when triggered by a user.

[0127] In this embodiment, the cab test device simulates these situations through precise delay control. Through the cooperation of the first delay relay 210, the second delay relay 220, the third delay relay 250 and the fourth delay relay 260, the tester can accurately control the time length of operations such as forward, reverse, rise and fall, and can easily change the test scenario, thereby more realistically simulating the complex working conditions in actual use, so that the test device can adapt to the testing requirements of cabs 300 to be tested of different models and specifications, and provide R&D personnel with more comprehensive and accurate evaluation results.

[0128] In this embodiment, when the first time delay relay 210 is closed, allowing the forward drive assembly 110 to rotate to the preset reversing position within a preset first duration, the third time delay relay 250 is triggered to initiate the test rise of the cab 300 under test. This triggering mechanism ensures a consistent and automated testing process, reducing the risk of human error. When the third time delay relay 250 remains closed for the preset third duration, the path between the power supply and the reversing drive assembly 130 is established, and the oil pump motor begins to drive the reversing hydraulic cylinder 700, thereby smoothly raising the cab 300 under test.

[0129] Similarly, when the tester wishes to perform a descent test, they can do so by closing the first delay relay 210, causing the reverse drive assembly 120 to rotate to the preset flip position within a preset second time duration, and then triggering the fourth delay relay 260. Once triggered, the fourth delay relay 260 remains closed for the preset fourth time duration, ensuring continuity between the power supply and the descent drive assembly 140. The oil pump motor then drives the tilt hydraulic cylinder 700 in reverse, causing the cab 300 under test to descend smoothly.

[0130] Please refer to Figure 4 、 Figure 9 as well as Figures 11 to 13 As shown, in one embodiment, based on the above Figure 2 、 Figure 3 、 Figure 7 as well as Figure 8 In the combined embodiment, the time delay switch assembly includes a first control assembly 230 and a second control assembly 270, wherein:

[0131] The first output end of the first control component 230 is connected to the controlled end of the first delay relay 210, and the second output end of the first control component 230 is connected to the controlled end of the second delay relay 220; the second control component 270 outputs a corresponding lifting control signal according to the flipping signal to control the third delay relay 250 or the fourth delay relay 260 to close.

[0132] The cab testing device further includes a rollover position detection assembly 500, wherein:

[0133] The output end of the flip position detection component 500 is connected to the input end of the first control component 230. The flip position detection component 500 is used to detect whether the flip position is vertical or horizontal to generate a corresponding flip signal; the first control component 230 is used to output a corresponding control signal according to the flip signal to control the first delay relay 210 or the second delay relay 220 to close.

[0134] The flip position detection assembly 500 includes a movable lever 510, a first fixed lever 520, and a second fixed lever 530, wherein:

[0135] The movable lever 510 is connected to the negative pole of the power supply; the first fixed lever 520 is electrically connected to the movable lever 510, and the first fixed lever 520 is used to output a horizontal flip signal to the first control component 230 when electrically connected to the movable lever 510; the second fixed lever 530 is electrically connected to the movable lever 510, and the second fixed lever 530 is used to output a vertical flip signal to the first control component 230 when electrically connected to the movable lever 510.

[0136] In this embodiment, the automation level of the cab testing apparatus is further enhanced by introducing a first control assembly 230 and a second control assembly 270. The first control assembly 230 and the second control assembly 270 work in conjunction, driving the forward drive assembly 110 and the reverse drive assembly 120 via the first delay relay 210 and the second delay relay 220, respectively, and detecting the position via the flip position detection assembly 500. Specifically, the forward drive assembly 110 and the reverse drive assembly 120 are connected to an operating motor, and the motor shaft of the operating motor is fixedly connected to one end of a movable lever 510. Driven by the operating motor, the movable lever 510 rotates left and right, electrically connecting to the first fixed lever 520 or the second fixed lever 530. This outputs a corresponding flip signal to control the closure of the third delay relay 250 or the fourth delay relay 260, thereby achieving precise control of operations such as raising and lowering the cab 300 under test.

[0137] Optionally, refer to Figure 9 Another embodiment of the present invention provides a cab testing device, based on the above Figure 7 and Figure 8 In the embodiment shown, when including the first control component 230 and the flip position detection component 500, the delay switch component 200 includes a second control component 270, wherein:

[0138] The second control component 270 outputs a corresponding lifting control signal according to the flip signal to control the third delay relay 250 or the fourth delay relay 260 to be closed.

[0139] In this embodiment, the second control component 270 can be implemented by a main controller, such as an MCU (Microcontroller Unit), a DSP (Digital Signal Process), an FPGA (Field Programmable Gate Array), a SOC (System On Chip), etc.

[0140] In this embodiment, the second control component 270 receives a flip signal from the flip position detection component 500. This flip signal reflects the current flip state or position of the cab 300 under test. Based on the received flip signal, the second control component 270 performs a logical analysis and outputs a corresponding lift control signal to achieve autonomous testing. This lift control signal directly controls the closure state of the third delay relay 250 or the fourth delay relay 260, thereby achieving precise control of the raising drive component 130 or the lowering drive component 140.

[0141] It can be understood that when the cab 300 to be tested needs to be raised for testing, the flip position detection component 500 will send a corresponding flip signal. After receiving this signal, the second control component 270 will output a corresponding control signal for controlling the rise to the third delay relay 250, so that the third delay relay 250 remains in a closed state within the preset third time length, and then opens the path between the power supply 400 end and the lifting drive component 130, driving the oil pump motor to work, so that the flip hydraulic cylinder 700 lifts the cab 300 to be tested.

[0142] Similarly, when the cab 300 to be tested needs to be lowered for testing, the flip position detection component 500 will send another type of flip signal, and the second control component 270 will output a control signal to keep the fourth delay relay 260 in a closed state within the preset fourth time length, thereby opening the path between the power supply 400 end and the descent drive component 140, driving the oil pump motor to work, so that the flip hydraulic cylinder 700 drives the cab 300 to be tested to land smoothly.

[0143] This design of controlling the closing of the third delay relay 250 or the fourth delay relay 260 according to the flip signal through two control components can not only ensure the accuracy and safety of the test, but also greatly improve the test efficiency, reduce the difficulty of operation, and make the test process more convenient and reliable.

[0144] Optionally, refer to Figure 10 Another embodiment of the present invention provides a cab testing device, based on the above Figure 9 In the illustrated embodiment, the time delay switch assembly 200 includes a second display assembly 280, wherein:

[0145] The second display component 280 is connected to the output end of the second control component 270. The second display component 280 is used to perform a countdown action according to the preset third time length or the preset fourth time length when the third delay relay 250 or the fourth delay relay 260 is triggered.

[0146] In this embodiment, the second display component 280 can be one or more LED display screens, LCD display screens, or other forms of display screens, which can intuitively display the remaining time in the current ascending or descending test process. By being connected to the output end of the second control component 270, the second display component 280 can receive the lifting control signal from the second control component 270 in real time, and determine whether the current phase is the ascending test or descending test based on these lifting control signals, thereby performing a corresponding countdown display according to the preset third duration or fourth duration, so that the tester can intuitively understand the remaining time of the current test, thereby better understanding the test progress. The tester does not need to frequently check or record the test time, and can easily understand the test progress and remaining time by simply observing the countdown information on the display screen, greatly reducing the operational complexity and time cost during the test process. At the same time, through the countdown method, the tester can also promptly identify possible problems in the test process, such as excessive test time or insufficient test time, so that timely intervention and adjustments can be made to ensure the accuracy and reliability of the test, reducing operational difficulty and time cost.
