With increasingly stringent safety standards management for commercial vehicles, the demand for mobile testing and on-site services has increased significantly, highlighting the limitations of traditional large-scale equipment. Furthermore, the inconvenience caused by the bulky equipment increases the risk of testing errors and affects data accuracy. Therefore, developing a lightweight and easy-to-operate vehicle side protection testing device has become an urgent need to address the challenges of using large-scale equipment. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a vehicle side protection test device, which solves the technical problem that existing vehicle side protection test devices are mostly fixed structures, have high weight, and need to be fixedly installed in a dedicated testing workshop, making them unsuitable for outdoor sites or on-site vehicle testing needs.

[0005] According to one aspect, at least one embodiment of this disclosure provides a vehicle side protection testing apparatus, comprising: The frame and the main frame, wherein the main frame is disposed within the frame; An adjustment assembly is disposed between the frame and the main frame; A detection component, wherein the detection component is mounted on the main frame; The detection component includes a servo electric cylinder, which is horizontally fixed on the main frame. A flat pressure head is provided at the output end of the servo electric cylinder, and a displacement grating digital display scale is provided between the flat pressure head and the surface of the main frame.

[0006] As a further technical solution, the adjustment component includes a pair of support seats, which are fixed to the top and bottom of the frame. Each support seat is horizontally rotatably connected to a rotating seat, and the rotating seats are rotatably connected to each other by a stud.

[0007] As a further technical solution, a transmission gear is provided on the upper surface of the rotating seat at the top, and a transmission shaft is vertically rotatably connected to the top of the frame. A drive gear is provided on the upper end of the transmission shaft, and the drive gear meshes with the transmission gear.

[0008] As a further technical solution, a pair of columns are fixedly connected between the rotating seats, the main frame is vertically and movably connected to the columns, and the main frame and the stud are connected by a threaded connection.

[0009] As a further technical solution, a worm gear is provided at the lower end of the transmission shaft, a worm is horizontally rotatably connected to the outer side of the frame, the worm meshes with the worm gear, and a crank handle is provided at the upper end of the stud.

[0017] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0018] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0019] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0020] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-3 As shown, it illustrates a vehicle side protection experimental device according to an embodiment of the present disclosure, comprising: The frame 1 and the main frame 2 are arranged inside the frame 1; Adjustment component 4 is disposed between the frame 1 and the main frame 2; Detection component 3, wherein the detection component 3 is disposed on the main frame 2; The detection component 3 includes a servo electric cylinder 3-1, which is horizontally fixed on the main frame 2. A flat pressure head 3-2 is provided at the output end of the servo electric cylinder 3-1, and a displacement grating digital display ruler 3-3 is provided between the flat pressure head 3-2 and the surface of the main frame 2.

[0024] In some examples, to achieve stable pressure testing of vehicle side protection performance, a testing component 3 is designed. This component includes a servo electric cylinder 3-1 horizontally fixed on the main frame 2, whose output end is rigidly connected to a flat pressure head 3-2. This provides stable and controllable thrust. The flat pressure head 3-2 has a flat surface, which can act evenly on the vehicle side protection structure, avoiding detection deviations caused by local stress concentration. The displacement grating digital display scale 3-3 between the flat pressure head 3-2 and the surface of the main frame 2 is parallel to the axis of the servo electric cylinder 3-1, which can measure the displacement of the flat pressure head 3-2 in real time, combined with the output force parameters of the servo electric cylinder 3-1.

[0025] During operation, the servo electric cylinder 3-1 pushes the flat pressure head 3-2 towards the side of the vehicle according to a preset program, continuously applying pressure upon contact. The displacement grating digital display scale 3-3 simultaneously records the displacement changes of the flat pressure head 3-2 until the preset pressure value is reached or the protective structure reaches its deformation limit. During the testing process, data is transmitted to the control system in real time, ensuring testing accuracy and traceability. The closed-loop control of the servo electric cylinder 3-1 enables precise adjustment of the pressure output, adapting to different testing standards; the flat design of the flat pressure head 3-2 ensures uniform force transmission, reflecting the true load-bearing capacity of the protective structure; the high-precision measurement of the displacement grating digital display scale 3-3 provides a reliable basis for performance analysis; the coordinated operation of these three components makes the testing process stable and controllable, reducing human error. This component, through automated pressure application and precise monitoring, provides scientific testing data for vehicle side protection experiments, ensuring the accuracy of the evaluation results.

[0026] like Figures 1-3 As shown in the figure, the adjustment component 4 in this embodiment includes a pair of support seats 4-1, which are fixed to the top and bottom of the frame 1. Each support seat 4-1 is horizontally rotatably connected to a rotating seat 4-2. The rotating seats 4-2 are rotatably connected to each other by a stud 4-3. A transmission gear 4-4 is provided on the upper surface of the rotating seat 4-2 located at the top. A transmission shaft 4-5 is vertically rotatably connected to the top of the frame 1, and a drive gear 4-6 is provided on the upper end of the transmission shaft 4-5. The drive gear 4-6 meshes with the transmission gear 4-4. A pair of columns 4-7 are fixedly connected between the rotating seats 4-2. The main frame 2 is vertically and movably mounted on the columns 4-7. The main frame 2 is connected to the stud 4-3 by a threaded connection. A worm gear 4-8 is provided at the lower end of the transmission shaft 4-5. A worm 4-9 is horizontally rotatably connected to the outer side of the frame 1. The worm 4-9 meshes with the worm gear 4-8. A crank handle 4-10 is provided at the upper end of the stud 4-3.

[0027] In some examples, to achieve flexible adjustment of the height and angle of the detection position and adapt to the detection needs of different vehicle models, an adjustment component 4 is designed. Support seats 4-1 are symmetrically distributed at the top and bottom of the frame 1. The inner horizontally rotating seat 4-2 can rotate around its own axis, providing rotational support for the stud 4-3, and simultaneously achieving angle adjustment through bearing connection. The stud 4-3 between the rotating seats 4-2 is threaded into the main frame 2. The uprights 4-7 on both sides are vertically fixed between the rotating seats 4-2. The main frame 2 is movably fitted onto the uprights 4-7, restricting the rotational freedom of the main frame 2, allowing it to only rise and fall vertically along the uprights 4-7. The transmission gear 4-4 on the upper end face of the top rotating seat 4-2 meshes with the drive gear 4-6 at the upper end of the transmission shaft 4-5. The worm gear 4-8 at the lower end of the transmission shaft 4-5 meshes with the worm 4-9 on the outer side of the frame 1. A crank handle 4-10 is located at the upper end of the stud 4-3, allowing manual rotation of the stud 4-3. When adjusting the height, rotating the worm gear 4-9 drives the worm wheel 4-8 and the drive shaft 4-5 to rotate. The drive gear 4-6 drives the rotating seat 4-2 and the stud 4-3 to rotate through the transmission gear 4-4. The main frame 2 rises and falls along the column 4-7 under the action of the thread, realizing the adjustment of the detection height. When adjusting the angle, loosening the locking device of the rotating seat 4-2 and rotating the stud 4-3 drives the rotating seat 4-2 to rotate, changing the horizontal angle of the main frame 2 and the detection component 3 to adapt to the detection needs of different positions on the side of the vehicle. After the adjustment is completed, locking the rotating seat 4-2 ensures structural stability. The worm gear 4-9 and worm wheel 4-8 transmission has a self-locking function to ensure the stability of the position after height adjustment. The guiding function of the column 4-7 ensures that the main frame 2 rises and falls smoothly and improves the positioning accuracy. The gear meshing transmission makes the angle adjustment flexible and can accurately control the rotation angle. The combination of manual and mechanical transmission takes into account both the convenience of adjustment and the structural reliability. This component, through multi-dimensional adjustment function, makes the detection device adaptable to different vehicle models and detection standards, expands the application range, and improves the flexibility of experiments.

[0028] For example, such as Figure 2 As shown, a screwing block 5 is provided at one end of the worm gear 4-9, and the screwing block 5 has a polygonal structure.

[0029] In some examples, the polygonal screw block 5 at one end of the worm gear 4-9 facilitates tool engagement and force application. Using a wrench or other tool to engage the polygonal structure allows for easier rotation of the worm gear 4-9, adjusting the height of the main frame 2 via the worm wheel 4-8 and worm gear 4-9 transmission. The polygonal design prevents tool slippage, ensuring stable force application and making height adjustment more precise and efficient. This is especially beneficial when fine adjustments to the inspection position are required, reducing operational errors and improving ease of adjustment.

[0030] For example, such as Figure 1 As shown, the main frame 2 can rotate 45° to both sides of the rotating seat 4-2 as the axis.

[0031] In some examples, the main frame 2 rotates 45° to each side around the rotating seat 4-2, covering a wider inspection range on the side of the vehicle. This angle adjustment range can adapt to the side curves of different vehicle models and the needs of different inspection points. Pressure testing can be performed on different tilt positions of the side without the need for moving devices, expanding the applicability of the experiment, while ensuring a smooth rotation process and ensuring that the inspection accuracy is not affected by the angle change.

[0032] For example, such as Figure 2 As shown, a pair of fixing plates 6 are provided at the lower end of the side surface of the frame 1, and a number of fixing holes 7 are provided on the surface of the fixing plates 6.

[0033] In some examples, a pair of fixing plates 6 and surface fixing holes 7 on the lower end of the side surface of the frame 1 are used to securely mount the device on the ground or experimental table. By connecting the device to the mounting surface through the fixing holes 7 with bolts, displacement or shaking of the device due to force during the experiment can be prevented, ensuring stable pressure application by the flat pressure head 3-2, improving the reliability of the test data, and enhancing the overall stability and safety of the device structure.

[0034] In practical use: The device is securely installed through the fixing holes 7 of the fixing plate 6. Rotating the screw block 5 of the worm gear 4-9 or cranking the handle 4-10 drives the stud 4-3 to rotate via the worm wheel 4-8, worm gear 4-9, and gear transmission. The main frame 2 is vertically raised and lowered along the column 4-7 to adjust its height. Simultaneously, the rotating seat 4-2 can rotate the main frame 2 45° to each side to accommodate different experimental angles. After adjustment, the servo electric cylinder 3-1 is activated, and its output pushes the flat pressure head 3-2 to apply pressure to the side of the vehicle. The displacement grating digital display 3-3 records the displacement changes of the flat pressure head 3-2 in real time, providing accurate feedback on experimental data. The entire operation is convenient, requiring no complex debugging, and adaptable to the experimental needs of various sites.
