[0034] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0035] like Figures 1 to 5 As shown, the utility model is a vehicle hood lifter performance simulation test device, comprising:

[0036] The base 1 has a cavity inside for accommodating components;

[0037] A guide post 2 is disposed in the cavity and extends in a vertical direction;

[0038] a workbench 3, disposed in the cavity, on which a fixed base 4 is mounted;

[0039] The fixing assembly 5 includes two sets of clamping mechanisms 51 symmetrically mounted on both sides of the fixing base 4 and a driving mechanism 52 for controlling the opening and closing of the clamping mechanisms 51;

[0040] The counterweight 6 is movably mounted just above the fixed component 5 and is slidably connected to the guide column 2;

[0041] The detection component 7 is installed at the bottom end of the counterweight 6 and includes a force sensor and a displacement sensor;

[0042] The base 1 is the basic structure of the entire test device, providing reliable support for the simulation test; the guide column 2 provides a track for the counterweight 6 to move up and down, and ensures that its movement path is stable. The counterweight 6 simulates the weight and movement of the hood in actual use, thereby testing the performance of the jack under different loads; during the test, the action of the clamping mechanism 51 is controlled by the driving mechanism 52 in the fixing assembly 5, so that the jack to be tested can be installed quickly and firmly. This design not only simplifies the operating process, but also ensures the stability and safety of the jack during the test; the force sensor and displacement sensor are used to measure the force exerted on the jack and its range of motion or stroke, respectively. These sensors can collect data in real time and analyze it through the connected data processing system to provide accurate test results. The integration of multiple types of sensors ensures the accuracy and reliability of the test data, providing a solid foundation for a comprehensive evaluation of the jack performance.

[0043] Specifically, the clamping mechanism 51 includes:

[0044] A fixed plate 511 is vertically arranged, and an optical sensor 514 is arranged on the top thereof;

[0045] The clamping positioning block 512 is fixedly mounted on one side wall of the two fixing plates 511 close to each other, and a V-shaped groove 513 is formed on the clamping surface of the clamping positioning block 512;

[0046] The fixing plate 511 is the main supporting structure of the clamping mechanism 51 and provides a basis for installing other components; the optical sensor 514 is used to detect whether the jack is correctly positioned. Only when the optical sensor 514 confirms that the jack is correctly positioned will the drive mechanism 52 start the clamping action. This mechanism increases the safety of operation and prevents accidental damage caused by incorrect positioning; the clamping positioning blocks 512 can move closer to each other to clamp the jack as the fixing plate 511 moves, ensuring that pressure is evenly applied from both sides, so that the jack remains stable during testing; the V-groove 513 is designed to accommodate jacks of different sizes and shapes, enhancing the applicability of the device.

[0047] To further enhance the clamping stability, a rubber layer is provided on the surface of the V-groove 513; the rubber material has a high coefficient of friction, which can significantly increase the friction between the V-groove 513 and the lifter, helping to ensure that the lifter is more stable during the test, thereby reducing the possibility of sliding or shifting.

[0048] The driving mechanism 52 includes a two-way cylinder 521 and a mounting member 522 for fixing the two-way cylinder 521. Both ends of the two-way cylinder 521 pass through the fixed base 4 and are connected to the fixed plate 511; the two-way cylinder 521 is the core component that drives the clamping positioning block 512 to open and close. Through air pressure control, it can achieve fast and precise movements, making the installation and disassembly of the lifter simple and quick; through precise air pressure adjustment, the size of the clamping force can be controlled to ensure that the lifter is subjected to appropriate clamping force during the test, and the sample will not be damaged due to excessive tightening, nor will the test be inaccurate due to excessive looseness; the two ends of the two-way cylinder 521 are connected to the fixed plate 511 to ensure the consistency and synchronization of the movement of the clamping positioning block 512, thereby avoiding the occurrence of uneven force on one side; the design of the mounting member 522 simplifies the installation and disassembly of the two-way cylinder 521, facilitates daily maintenance and inspection, and reduces maintenance costs.

[0049] In order to cope with the possible deformation of the fixed base 4 and the clamping mechanism 51 after long-term use, and to ensure that the force applied by the lifter is not too large to damage the clamping parts, a through installation groove is opened in the middle of the fixed base 4, and a limit plate 42 is installed in the installation groove for abutting against the end of the lifter; the limit plate 42 also allows the force to be dispersed through the installation groove, reducing the pressure directly transmitted to the fixed base 4; the limit plate 42 is made of wear-resistant and pressure-resistant material, and is designed to be easy to disassemble, so that it is easy to replace or adjust as needed.

[0050] In order to evenly distribute the clamping force, the driving mechanism 52 is set into two groups, and a hollow cavity is provided in the fixed base 4, and the two groups of driving mechanisms 52 are symmetrically arranged in the hollow cavity; the hollow cavity provides an installation space for the driving mechanism 52, which not only saves external space but also protects the driving mechanism 52 from the influence of the external environment; the symmetrical layout of the two groups of driving mechanisms 52 ensures uniform distribution of force, so that the clamping positioning block 512 can move synchronously to avoid the occurrence of uneven force on one side; at the same time, the two driving mechanisms 52 can work at the same time, shortening the clamping or release time and improving work efficiency.

[0051] Preferably, a plurality of guide columns 2 are provided, and the two opposite sides of the counterweight 6 are respectively slidably connected to the guide columns 2; through the joint action of multiple guide columns 2, the movement of the counterweight 6 is made more stable, reducing shaking and unnecessary displacement; by sharing the weight of the counterweight by multiple guide columns 2, the load of a single guide column 2 can be effectively reduced, and its service life can be extended.

[0052] Preferably, a guide hole that cooperates with the guide column 2 is provided on the counterweight 6, and a sliding sleeve 21 that slides with the guide column 2 is embedded in the guide hole; the sliding sleeve 21 is made of low-friction material and plays a role of isolation and protection to prevent the counterweight 6 from directly contacting the guide column 2. This design can reduce the friction between the counterweight 6 and the guide column 2, so that the counterweight 6 can move up and down along the guide column 2 more easily, reducing energy loss.

[0053] To improve the safety of operation, an opening 11 is provided on the front face of the machine base 1, and a visual window 12 is slidably installed in the opening 11, and a storage slot corresponding to the visual window 12 is provided in the machine base 1; the design of the opening 11 provides a convenient channel for taking and placing the jacking device, and combined with the visual window 12, the opening 11 can be closed during the test, and the jacking device can be observed in real time to ensure the safety and transparency of the test process; the storage slot provides a safe storage location for the visual window 12 to avoid damage caused by external collision or dust accumulation.

[0054] In order to realize the centralized control of the whole test process, the present device further comprises a control unit 8, which comprises: an electric control box 81 and a human-computer interaction platform 82, the human-computer interaction platform 82 being in communication with the electric control box 81, the human-computer interaction platform 82 being used to issue instructions to the electric control box 81, and the electric control box 81 being used to execute the instructions;

[0055] The electric control box 81 includes a PLC controller for storing programs;

[0056] The electric control box 81 is in communication with the fixing assembly 5 and the detection assembly 7;

[0057] The control unit 8 is responsible for coordinating and managing the work of all mechanical and electronic components. Through the cooperation of the PLC controller and the human-computer interaction platform 82, the test process is highly automated, manual intervention is reduced, and work efficiency is improved. Through real-time data collection and processing, the accuracy and consistency of test results can be ensured, thereby improving test quality.

[0058] The utility model provides a performance simulation test device for a car hood lifter. When working, the visual window 12 is first lowered, and the lifter to be tested is placed in the space between the two clamping positioning blocks 512 through the opening 11 on the front end face of the machine base 1. The bottom end of the lifter abuts against the limit plate 42, and the correct position is verified by the optical sensor 514, and the visual window 12 is raised to close the opening 11; the test parameters are input through the human-computer interaction platform 82, and the test type to be performed is selected. The human-computer interaction platform 82 sends these parameters and instructions to the electric control box 81. After receiving the instructions, the PLC controller parses and processes them according to the preset program; the electric control box 81 sends instructions to the two sets of symmetrically arranged drive mechanisms 52 through the communication interface to start the two-way cylinder 521; the two-way cylinder 521 pushes the clamping positioning block 512 to retract inward to achieve uniform clamping of the lifter, and the rubber layer on the surface of the V-groove 513 increases the friction Friction ensures stable clamping and protects the surface of the jack from damage; adjusts the position of the counterweight 6 according to the test requirements, so that it moves downward along the multiple guide columns 2 and contacts the jack, simulating the weight of the hood in actual use; the sliding sleeve 21 in the guide hole reduces the friction, so that the counterweight 6 can move more easily, ensuring smooth movement; the jack is started, and the force sensor and displacement sensor in the detection component 7 collect the force and movement range or stroke of the jack in real time. These data are transmitted to the electrical control box 81 through the communication interface. The PLC controller processes the received data, generates test results, and displays them on the human-computer interaction platform 82; after the test is completed, the drive mechanism 52 is reversed to release the clamping positioning block 512, so that the jack can move freely, and the counterweight 6 moves upward along the guide column 2 and returns to its initial position; the operator takes out the jack through the opening 11 to complete the disassembly process.
