[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments, but these specific embodiments do not limit the scope of protection of the present invention in any way.

[0028] Example 1

[0029] like Figures 1-4 As shown, a portable vehicle side protection testing device includes a dedicated toolbox assembly 1, a loading device, and a measurement and control system assembly. The testing device emphasizes portability and modular design, thus keeping the total weight below 30 kg.

[0030] In this embodiment, the special toolbox assembly 1 is made of profiles and end plates, with an internal support frame. Specifically, a maintenance-free miniature slide rail 2 is arranged on one side of the box 11, which serves as a lifting support for the loading mechanism. Rollers 12, a telescopic rod 13, and a handle 14 are arranged on the box 11 for carrying and transporting the equipment. The foamed material lining inside the box 11 is pre-formed according to the shape of the loading device and the measurement and control system assembly, forming a receiving groove that matches the equipment contour. This groove is specifically designed to accommodate the loading device and the measurement and control system assembly, effectively preventing collisions during transport.

[0031] In this embodiment, a loading device mounting plate 3 is installed on the slide rail 2. The plate 3 and the tail of the loading device are designed with a slotted structure. Specifically, the plate 3 is equipped with two star-shaped handle screws, which can be used to lock the loading device at any height within the range of 300-650mm. During installation, simply unscrew either star-shaped handle screw to slide the loading device into the slot. After adjustment, tighten it slightly to prevent slippage.

[0032] In this embodiment, the loading device adopts an electric cylinder assembly 4 structure. The maximum working force of the loading device is not less than 1.5KN, and the loading speed range is 1-50mm / s. It mainly includes: an electric cylinder barrel, a drive system and a sensing system integrated within the electric cylinder barrel. The drive system includes an integrated servo motor connected to a ball screw via a synchronous belt pulley reduction drive. The sensing system includes a standard spoke-type pressure sensor 5 and a wire displacement sensor 6, wherein the pressure sensor 5 has a range of not less than 2KN, and the displacement sensor 6 has a range of not less than 250mm. The loading device is equipped with a 220mm diameter circular pressure head, which uses a spherical hinge design with the sensor to ensure uniform force transmission during loading. All control lines, communication cables, and sensor cables are integrated into a single design, connected via aviation plugs, and protected by a housing.

[0033] In this embodiment, the measurement and control system is externally encapsulated in a flame-retardant plastic electrical control box 7. Internally, it houses electrical components such as a touchscreen 8, controller, and transmitter. The power supply system includes a power supply and a power inverter, and is equipped with a cooling fan. Specifically, the control box 7 panel has two rocker switches: one is a main power control switch 9 "ON / OFF," and the other is a power selection switch 10. The panel also features illuminated metal "Load" and "Retract" buttons 11. The side of the box 11 has a power input interface and a communication interface for connecting the loading device and an external power source.

[0034] The device also includes the following auxiliary connection structures: the measurement and control system and the loading device are connected by an integrated wiring harness with a quick-plug connector; the power cable adopts a 2-in-1-out design, where the 2 inlets are 220V standard plugs and 12V vehicle battery clamps, and the 1 outlet is an aviation plug.

[0035] As an scalable solution, this portable vehicle side protection testing device can be equipped with a mounting bracket and expansion bolts (not shown in the figure) for fixing needs in the absence of a reaction wall. The mounting bracket has a U-shaped structure, with one end connected to the special toolbox assembly 1 and the other end fixed to the ground by expansion bolts. The expansion bolts are expansion bolts, and M12 or M16 specifications can be selected according to the ground conditions.

[0036] The portable vehicle side protection testing device of this embodiment achieves the following technical effects through the combination of the above structures:

[0037] 1. The modular design and quick-connect structure give the device excellent portability and ease of assembly;

[0038] 2. The combination of slide rail 2 and locking structure enables flexible adjustment of the loading height;

[0039] 3. The dual power supply switching design expands the application scenarios of the device.

[0040] The working principle and method of the above-mentioned portable vehicle side protection testing device are as follows:

[0041] First, install the power supply and fixing devices. Select the power supply method according to the test site conditions: when using mains power, connect through a 220V standard plug and select position I on power selection switch 10; when using vehicle power, connect through a 12V vehicle battery clamp and select position II on power selection switch 10. For fixing, you can choose to use a reaction wall for support or use expansion bolts for ground anchoring, depending on the site conditions.

[0042] Next, assemble the equipment. Remove the loading device from the dedicated toolbox 1 and install it to the required height using the sliding rail 2 and the sliding plate 3. Specifically: loosen the star-shaped handle screw on the sliding plate 3, install the loading device onto the sliding plate 3 via the slot structure, adjust it to a suitable height within the range of 300-650mm, and then tighten the star-shaped handle screw to lock it in place. Then, remove the measurement and control system assembly and quickly connect it to the loading device via the aviation connector of the integrated wiring harness.

[0043] Next, after the equipment is installed, system parameters are set. Parameters such as loading force and displacement are set via the touchscreen 8. The system controls a servo motor to drive a ball screw, and force is transmitted through a synchronous belt pulley reduction gear. During loading, pressure sensor 5 and displacement sensor 6 collect data in real time and feed it back to the control system. The spherical hinge structure ensures uniform force transmission.

[0044] Finally, the equipment is stored after the test is completed. The loading device is removed from the slide plate 3 and stored in the special toolbox 1. During transportation, the two star-shaped handle bolts on the slide plate 3 are secured simultaneously, and the screw heads are screwed into the mounting holes of the linear guide rail 2 to ensure safe transportation.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any innovative improvements or substitutions based on the present invention should fall within the scope of the claims of the present invention. Furthermore, the parameters, materials, and processes mentioned in the above embodiments are not unique. Without departing from the technical essence of the present invention, those skilled in the art can make various alternative choices, and these alternative solutions should also be considered to fall within the scope of protection of the present invention.
