[0035] With the rapid development of automotive electronic control technology, the electronically controlled suspension system, as a key technology to improve the handling and comfort of vehicles, has been widely used in high-end vehicles and the field of intelligent vehicles. The electronically controlled suspension system includes multiple electronically controlled suspensions. By electronically controlling multiple parameters of the electronically controlled suspensions, such as damping, height, and stiffness, to cope with different road conditions and driving requirements, the driving and riding experience has been greatly improved. However, the introduction of this technology has also brought new challenges to the product development and verification work. How to verify the functions and performance of the electronically controlled suspension system through efficient bench tests before vehicle tests, reduce the problems in vehicle verification, and shorten the development cycle has become an urgent problem to be solved.

[0036] To solve this problem, an embodiment of the present utility model provides a loading device, which is applied to the test of the electronically controlled suspension 400. The specific structure and function of the loading device provided by the embodiment of the present utility model will be further described below in combination with the text and the accompanying drawings.

[0037] Refer to Figure 1As shown in the figure, the loading device provided by an embodiment of the present utility model includes: a base 100, a bracket 200, and a test component 300. The bracket 200 is a frame structure and is connected to the upper end surface of the base 100. The test component 300 is between the base 100 and the bracket 200, which can ensure the convenience and stability of the connection between some components of the test component 300 and the base 100 and the bracket 200.

[0038] Referring to Figure 1 and Figure 2 As shown in the figure, in some embodiments, the test component 300 includes a load generator 310, a lower connecting seat 320, and an upper connecting seat 330. The load generator 310 is disposed in the base 100. The load generator 310 has an output shaft protruding from the upper end surface of the base 100. The lower connecting seat 320 is disposed at the upper end of the output shaft of the load generator 310. The output shaft of the load generator 310 can move up and down so as to drive the lower connecting seat 320 to move up and down. The upper connecting seat 330 is connected to the bracket 200 and is located above the lower connecting seat 320. An installation position for installing an electronic control suspension 400 is defined between the lower connecting seat 320 and the upper connecting seat 330. After the electronic control suspension 400 is installed in the installation position, the load provided by the load generator 310 can act on the electronic control suspension 400 through the output shaft and the lower connecting seat 320, thereby being able to simulate the force conditions under different working conditions.

[0039] Referring to Figure 1 and Figure 2 As shown in the figure, in some embodiments, the test component 300 further includes a force sensor 340 and a displacement sensor 350. The force sensor 340 is disposed on the upper side of the upper connecting seat 330. Since the electronic control suspension 400 is installed in the installation position defined between the lower connecting seat 320 and the upper connecting seat 330, the load provided by the load generator 310 can be transmitted to the upper connecting seat 330 through the output shaft, the lower connecting seat 320, and the electronic control suspension 400. The force sensor 340 located on the upper connecting seat 330 can detect the force acting on the upper connecting seat 330, thereby being able to indirectly obtain the load acting on the electronic control suspension 400. The displacement sensor 350 is disposed on one side of the lower connecting seat 320. When the load generated by the load generator 310 is transmitted to the electronic control suspension 400, the electronic control suspension 400 will undergo elastic deformation, which will cause the position of the lower connecting seat 320 to change. The displacement sensor 350 detects the displacement of the lower connecting seat 320, thereby being able to indirectly measure the deformation amount of the electronic control suspension 400.

[0040] In some embodiments, when testing using the loading device provided by the embodiments of the present utility model, the electronically controlled suspension 400 to be tested is installed at the installation position between the lower connection seat 320 and the upper connection seat 330. Then, a predetermined load is applied through the load generator 310 to simulate the force-bearing situation under actual working conditions. At the same time, the force sensor 340 detects the force acting on the upper connection seat 330 in real time and transmits the data to the data processing system for analysis. The displacement sensor 350 detects the displacement of the lower connection seat 320 in real time and also transmits the data to the data processing system for analysis. Finally, based on the data of the force sensor 340 and the displacement sensor 350, it is evaluated whether the functions and performance of the electronically controlled suspension 400 meet the design requirements.

[0041] It can be understood that the lower connection seat 320 can be fixed to the output shaft of the load generator 310 by welding or detachably connected to the output shaft of the load generator 310; similarly, the upper connection seat 330 can be fixed to the bracket 200 by welding or detachably connected to the bracket 200; when the lower connection seat 320 is detachably connected to the output shaft of the load generator 310 and the upper connection seat 330 is detachably connected to the bracket 200, different models of the upper connection seat 330 and the lower connection seat 320 can be replaced so that the loading device can perform a loading test on different models of the electronically controlled suspension 400.

[0042] The loading device provided by the embodiments of the present utility model, through the cooperation of the load generator 310, the lower connection seat 320, the upper connection seat 330, the force sensor 340, and the displacement sensor 350, can comprehensively and accurately simulate and detect the performance of the electronically controlled suspension 400 under different working conditions. This significantly improves the accuracy and efficiency of verification, enabling potential problems to be fully discovered and solved before the vehicle-level test, thereby reducing the failures and debugging time in the vehicle-level verification.

[0043] Refer to Figure 1 and Figure 2As shown, according to the loading device provided by the embodiment of the present utility model, the bracket 200 includes two vertical beams 210 and a cross beam 220. The two vertical beams 210 are respectively arranged on both sides of the base 100, ensuring the lateral stability and balance of the loading device. The cross beam 220 is arranged horizontally, and its two ends are respectively connected to the two vertical beams 210, forming a stable frame structure. The cross beam 220 is located above the lower connecting seat 320, and the upper connecting seat 330 is connected to the middle position of the cross beam 220. Such a design enables the upper connecting seat 330 to stably support the electronic control suspension 400, and ensures that during the test, the force-bearing condition of the electronic control suspension 400 can be evenly distributed, thereby improving the accuracy and reliability of the test. Generally speaking, this structural design of the connecting frame not only enhances the stability and load-bearing capacity of the loading device, but also provides a strong guarantee for realizing the accurate performance test of the electronic control suspension 400.

[0044] It can be understood that the lower ends of the two vertical beams 210 can be fixed to the upper end of the base 100 by welding, or can be fixed to the upper end of the base 100 by fasteners. The two ends of the cross beam 220 can be respectively fixed to the two cross beams 220 by welding, or can be connected to the two cross beams 220 by fasteners.

[0045] Refer to Figure 1 and Figure 2 As shown, according to the loading device provided by the embodiment of the present utility model, the two vertical beams 210 are arranged vertically on the base 100, and the two horizontal ends of the cross beam 220 are respectively slidably connected to the two cross beams 220, and the cross beam 220 is slidably connected to the two vertical beams 210. During the actual test process, according to the specific dimensions and installation requirements of the electronic control suspension 400, the position of the cross beam 220 can be easily adjusted to ensure that the electronic control suspension 400 can be accurately and stably installed between the upper connecting seat 330 and the lower connecting seat 320. This enables the loading device to adapt to various electronic control suspensions 400 with different sizes and shapes, improving the versatility and flexibility of the device. In addition, since the cross beam 220 can slide in the vertical direction, testers can more easily install the electronic control suspension 400 at the test position and make precise adjustments. This greatly shortens the test preparation time and improves the test efficiency.

[0046] It can be understood that sliding sleeves can be provided at both ends of the cross beam 220, and sliding bearings, rollers or slide rail structures can be arranged inside the sliding sleeves to realize the sliding connection between both ends of the cross beam 220 and the two vertical beams 210.

[0047] Refer to Figure 2As shown, for the loading device provided according to an embodiment of the present utility model, locking members (not shown in the figure) are respectively provided at both ends of the cross beam 220. The locking members are configured to be able to lock the cross beam 220 between two vertical beams 210, so that the cross beam 220 can hover and be fixed above the lower connecting seat 320. Specifically, the locking members can adopt various forms, such as but not limited to bolts, clamps, buckles or other mechanical structures that can achieve the fastening function. During the specific assembly process, first slide the cross beam 220 to a predetermined position. Subsequently, install the locking members at both ends of the cross beam 220 and operate the locking members to tighten them, thereby firmly locking the cross beam 220 between the vertical beams 210. The design of the locking members should ensure that during the use of the loading device, the cross beam 220 will not be displaced or loosened due to external forces, thus ensuring the stability and safety of the loading device.

[0048] Referring to Figure 1 As shown, for the loading device provided according to an embodiment of the present utility model, the load generator 310 is selected as a hydraulic press or a linear motor. Both of these devices can provide stable and controllable loads and are suitable for various test and application scenarios. When a hydraulic press is selected as the load generator 310, the lower connecting seat 320 will be designed and connected to the output shaft of the hydraulic press. The hydraulic press transmits force and motion through its output shaft, thereby realizing the loading of the object to be tested. If a linear motor is selected as the load generator 310, the lower connecting seat 320 will also be connected to the output shaft of the linear motor. The linear motor can provide precise and rapid linear motion, enabling the loading device to achieve more complex and dynamic tests.

[0049] It can be understood that the connection between the lower connecting seat 320 and the output shaft of the load generator 310 needs to ensure firmness and stability, so as not to loosen or fall off during the loading process, thereby ensuring the accuracy and safety of the test.

[0050] The loading assembly provided according to an embodiment of the present utility model includes the loading device provided according to an embodiment of the present utility model, and the loading assembly has all the beneficial effects of the loading device provided according to an embodiment of the present utility model.

[0051] It can be understood that the loading assembly can include different load generators 310 (such as a hydraulic press or a linear motor) to flexibly adapt to different test requirements, provide stable and controllable load forces, and thereby achieve effective loading tests on various test specimens or systems.

[0052] Referring to Figure 3, according to the loading assembly provided by the embodiments of the present invention, it further includes an air supply mechanism. The air supply mechanism includes a compressor, and the compressor has an air pipe which can extend to one side of the loading device and is configured to be connectable to the electronic control suspension 400. Through such a design, the air supply mechanism can provide necessary pneumatic support for the electronic control suspension 400 to ensure its normal operation and response to the load force generated by the loading device during the test. This integrated air supply mechanism enhances the functionality and practicality of the loading assembly, enabling it to more comprehensively meet the requirements for loading tests on the electronic control suspension 400.

[0053] Referring to Figure 3 , according to the loading assembly provided by the embodiments of the present invention, it includes at least four loading devices. The at least four loading devices are arranged at intervals, and the air supply mechanism has at least four air pipes. The at least four air pipes respectively extend to one side of the at least four loading devices. The at least four loading devices ensure that independent loading tests can be carried out on multiple different electronic control suspensions 400. In addition, to cooperate with this design, the compressor of the air supply mechanism is correspondingly equipped with at least four air pipes. Each air pipe extends to one side of a loading device and is connected to the electronic control suspension 400. Such a design enables each loading device to independently receive pneumatic support from the air supply mechanism, thereby ensuring that each loading device can operate normally and generate the required load force during the test. This design of multiple loading devices and multiple air pipes further improves the test ability and flexibility of the loading assembly, enabling it to more comprehensively cover different test requirements of the electronic control suspension 400 and reducing the test time.

[0054] The test system provided by the embodiments of the present invention is applied to the loading assembly provided by the embodiments of the present invention.

[0055] Referring to Figure 3 , according to the test system provided by the embodiments of the present invention, the test system can preferably control the load generator 310 and can comprehensively and accurately simulate and detect the performance of the electronic control suspension 400 under different working conditions. This significantly improves the accuracy and efficiency of verification, enabling potential problems to be fully discovered and solved before the vehicle test, thereby reducing the faults and debugging time in the vehicle verification.

[0056] Referring to Figure 3, according to the test system provided by the embodiments of the present utility model, it further includes a simulation system. The simulation system is electrically connected to the loading device and the air supply mechanism, forming a highly integrated test environment. Through such a design, the simulation system can receive data from the loading device and the air supply mechanism in real time, and simulate actual working conditions or test scenarios based on these data. This test system integrating the simulation system not only improves the accuracy and reliability of the test, but also can simulate more complex and changeable test conditions, so as to more comprehensively evaluate the performance and performance of the entire electronic control suspension system. This highly integrated and intelligent test system will provide stronger support for product R & D, quality control and performance verification.
