Description

Technical Field

[0001] This application relates to the field of intelligent driving technology, and in particular to assembly frames, test benches, and test systems. Background Technology

[0002] With the continuous development of intelligent chassis technology, the installation volume of CDC dampers in vehicles is increasing. CDC dampers, or Continuous Damping Control, are a type of control system that can automatically adjust and continuously reduce vibrations. Because the damping of CDC dampers is continuously adjustable and the adjustment speed is fast, the testing requirements for test benches regarding the continuously adjustable damping and high-speed motion adjustment characteristics of CDC dampers are becoming more stringent.

[0003] However, existing test benches are prone to motion deviation when testing CDC dampers at high speeds, making it impossible to accurately test according to the preset motion trajectory. This fails to meet the growing testing needs and restricts the technological development of CDC dampers. Utility Model Content

[0049] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0050] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0051] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0052] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0053] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0054] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0055] See Figures 1 to 4 As shown, this application provides a test bench for damper experimental testing. The test bench includes an assembly frame 10000, a power mechanism 20000, a guide mechanism 30000, and a balancing mechanism 40000. The assembly frame 10000 serves as the assembly base for the power mechanism 20000, guide mechanism 30000, and balancing mechanism 40000. The specific dimensions and structure of the assembly frame 10000 can be specifically designed based on the assembly requirements of the power mechanism 20000, guide mechanism 30000, and balancing mechanism 40000. The assembly frame 10000 is configured to define a linear motion trajectory, which limits the movement of the power mechanism 20000.

[0056] The power mechanism 20000 includes a power source and a motion component. The power source is mounted on the assembly frame 10000, and the motion component is mounted on the assembly frame 10000 along a motion trajectory. The power source and the motion component drive each other. The power source can adopt different types of power such as electromagnetic power and mechanical power. The power source provides the energy source for the motion of the motion component. Thus, the power source can drive the motion component to reciprocate relative to the assembly frame 10000 along the motion trajectory at a preset motion speed. This motion speed can be adjusted according to actual needs. Thus, when the motion component is connected to the damper, the motion of the motion component can synchronously drive the damper to move at the same speed. This method is used to control the damper to simulate operation and test the working condition of the damper.

[0057] During the operational testing of the damper by the aforementioned motion component, the guide mechanism 30000 further provides guiding assistance to the motion component, and the balancing mechanism 40000 further provides balancing assistance to the motion component. Specifically, the guide mechanism 30000 is mounted on the assembly frame 10000 and is configured to form a guide trajectory. The guide trajectory is a straight line and parallel to the motion trajectory. The motion component is movably assembled relative to the guide mechanism 30000 along the guide trajectory. The balancing mechanism 40000 is mounted on the assembly frame 10000, and at least one of the guide mechanism 30000 and the power mechanism 20000 is mounted on the balancing mechanism 40000.

[0058] The guiding aid is mainly used to ensure that the moving components move accurately along the motion trajectory during high-speed movement, and to prevent the movement of the moving components from deviating when the movement speed is too high. The balancing mechanism 40000 is mainly used to ensure that the moving components maintain stability during high-speed movement, and to prevent the moving components from becoming unstable relative to the assembly frame 10000 when the movement speed is too high, which would lead to deviation of the movement.

[0059] Therefore, it can be seen that the guiding and balancing assistance provided by the guiding mechanism 30000 and the balancing mechanism 40000 to the power mechanism 20000 can ensure that the motion components of the power mechanism 20000 maintain high precision and high stability during the motion test of the damper. When the motion component increases its speed, it can also effectively test the working condition of the damper. In the context of the rapid development of CDC dampers, it provides stable test conditions for the characteristics of CDC dampers that the damping is continuously adjustable and the adjustment speed is fast, thus meeting the higher test requirements of CDC dampers.

[0060] Regarding the aforementioned assembly frame 10000, in one embodiment, the assembly frame 10000 includes a frame body 11000 and an outer protective cover 12000. The frame body 11000 includes a frame base 11100, a frame partition 11200, a frame assembly 11300, and a column assembly 11400. The frame partition 11200 is assembled onto the frame base 11100 via the column assembly 11400, forming a spatial region of a certain height between the frame partition 11200 and the frame base 11100. At this time, the frame assembly 11300 can be assembled within the spatial region formed between the frame partition 11200 and the frame base 11100. Between the frame partition 11200 and the frame base 11100, the frame assembly 11300 is configured for assembling at least one of the power mechanism 20000, the guide mechanism 30000, and the balancing mechanism 40000 of the test bench.

[0061] Therefore, in order to ensure the stability of the assembly of the power mechanism 20000, the guide mechanism 30000, and the balancing mechanism 40000 between the frame partition 11200 and the frame base 11100, a very stable assembly structure can be formed between the frame partition 11200, the frame base 11100, and the frame assembly 11300. This ensures that even though the moving components of the power mechanism 20000 will exert a large impact force on the frame body 11000 during high-speed movement, the frame partition 11200, the frame base 11100, and the frame assembly 11300 in the frame body 11000 can also resist the large impact force based on the more stable assembly structure, thereby providing stable test conditions and meeting the higher test requirements of the CDC damper.

[0062] In one embodiment, the frame partition 11200 has at least one first latching portion 11600, the frame base 11100 has at least one second latching portion 11700, and the frame assembly 11300 has at least one locking portion 11800. Therefore, the top of the frame assembly 11300 can be positioned and latched to the first latching portion 11600 of the frame partition 11200, and the bottom of the frame assembly 11300 can be positioned and latched to the second latching portion 11700 of the frame base 11100. At the same time, the frame assembly 11300 can also be connected to the column assembly 11400 through at least one locking portion 11800.

[0063] Since the frame partition 11200 is located above the frame base 11100, the frame partition 11200 and the frame base 11100 are in a longitudinal relative position. The motion trajectory defined by the assembly frame 10000 is also a straight line trajectory in the longitudinal direction. For example, the line connecting the center of the frame partition 11200 and the center of the frame base 11100 can be defined to be parallel to the motion trajectory. Therefore, when the motion component of the power mechanism 20000 reciprocates along the motion trajectory, it actually moves between the frame partition 11200 and the frame base 11100.

[0064] At this time, since the frame partition 11200 and the frame base 11100 are respectively snapped together with the frame assembly 11300 based on the first snap-fit ​​part 11600 and the second snap-fit ​​part 11700, it can be ensured that when the moving assembly moves at high speed along the movement trajectory, the impact force applied along the movement trajectory direction is offset by the reliable snap-fit ​​connection of the first snap-fit ​​part 11600 and the second snap-fit ​​part 11700. Alternatively, at least based on the first snap-fit ​​part 11600 and the second snap-fit ​​part 11700, the frame assembly 11300 forms a stable assembly connection with the frame partition 11200 and the frame base 11100 in the longitudinal direction, which to a certain extent offsets the impact force applied when the moving assembly moves at high speed.

[0065] The outer protective cover 12000 has a frame assembly space inside, and the outer protective cover 12000 is disposed outside the frame body 11000. At least a portion of at least one of the frame partition 11200, frame assembly 11300, and column assembly 11400 is configured for assembly in the frame assembly space. In one embodiment, the frame assembly space includes at least a first frame unit space and a second frame unit space, which are spaces separated from the frame assembly space. The first frame unit space is located between the frame partition 11200 and the frame base 11100, and the second frame unit space is located above the frame partition 11200.

[0066] The frame partition 11200 has a through-hole configured to connect the first frame unit space and the second frame unit space. The frame assembly 11300 is housed in the first frame unit space, and a portion of the column assembly 11400 is housed in the second frame unit space. Therefore, when the power mechanism 20000 is assembled in the first frame unit space opposite to the frame assembly 11300, at least a portion of the motion component of the power mechanism 20000 can enter the second frame unit space through the through-hole. At this time, the damper under test can be controlled to move within the second frame unit by being driven by the motion component. This allows the power mechanism 20000 and the damper being tested by the power mechanism 20000 to be located in different spaces, namely, in the first frame unit space and the second frame unit space, respectively.

[0067] In one embodiment, the outer protective cover 12000 includes a first unit cover 1210012100 and a second unit cover 1220012200, which together constitute the outer protective cover 12000. The first unit cover 1210012100 is assembled between the frame partition 11200 and the frame base 11100, and the inner cavity of the first unit cover 1210012100 is configured to form a first frame unit space between the frame partition 11200 and the frame base 11100. The second unit cover 12200 is mounted on the frame partition 11200. The inner cavity of the second unit cover 12200 is configured to form a second frame unit space on the frame partition 11200. At least a portion of the second unit cover 12200 is a viewing area. Therefore, when the damper moves within the second frame unit space, the movement of the damper can be observed using the viewing area.

[0068] In one embodiment, the frame body 11000 further includes a frame top seat 11500, which is assembled onto the column assembly 11400 and located above the frame partition 11200. The second frame unit space is located between the frame top seat 11500 and the frame partition 11200. Therefore, the frame top seat 11500, the frame partition 11200, and the frame base 11100 can be integrated. The space between the frame partition 11200 and the frame base 11100 forms the second frame unit space. The frame top seat 11500, the frame partition 11200, and the frame base 11100 are integrated using the column assembly 11400, which further enhances the structural stability of the frame body 11000.

[0069] The frame assembly 11300 can be constructed into various different structural shapes according to the requirements of the assembly power mechanism 20000, the guide mechanism 30000 and the balancing mechanism 40000. For example, it can be composed of a suitable number of plate structures. In one embodiment, the frame assembly 11300 may include a frame base plate 11310 and two frame upright plates 11320. The frame base plate 11310 is vertically assembled to the frame base 11100, and the two frame upright plates 11320 are vertically assembled to the frame base 11100. The two frame upright plates 11320 are respectively connected to the left and right sides of the frame base plate 11310. At this time, the two frame upright plates 11320 can be perpendicular to the frame base plate 11310.

[0070] The frame base plate 11310 and two frame uprights 11320 are configured as a guide mechanism 30000 for fixing and assembling the test bench. The guide mechanism 30000 is guided and assembled with the power mechanism 20000. Therefore, the frame base plate 11310 can be provided with motion clearance holes 11311, allowing the motion components of the power mechanism 20000 to move within the motion clearance holes 11311. That is, the motion clearance holes 11311 can be configured to allow the motion components of the power mechanism 20000 of the test bench to move within them. At this time, the motion clearance holes 11311 can be provided with a suitable hole shape in a strip or linear form along the direction of the motion trajectory to meet the reciprocating motion of the motion components within them. The purpose of providing the motion clearance holes 11311 is twofold: first, to meet the movement of the motion components; and second, to limit the movement range of the motion components within the motion clearance holes 11311. It also serves a safety limiting function, preventing the motion components from disengaging from the motion clearance holes 11311 due to high-speed movement, thereby improving the safety and stability of the movement.

[0071] In one embodiment, the frame assembly 11300 also includes a frame cross member 11330 or a support corner plate 11340, etc. The number of frame cross members 11330 is configured to be at least two, and the two sides of the two frame uprights 11320 are fixedly connected by at least one frame cross member 11330. The frame cross member 11330 can further reinforce the two frame uprights 11320 and improve the assembly stability of the entire frame body 11000. At least one frame upright plate 11320 can be supported and connected to at least one of the frame base 11100 and the frame partition 11200 through at least one supporting corner plate 11340. At this time, the frame base 11100 and the frame partition 11200 are parallel to each other, and the frame upright plate 11320 is perpendicular to the frame base 11100 and the frame partition 11200. The angle of the supporting corner plate 11340 can also be 90°. Therefore, several supporting corner plates 11340 can be used to ensure that the frame upright plate 11320 is perpendicular to the frame base 11100 and the frame partition 11200.

[0072] The first mounting portion 11600 and the second mounting portion 11700 can be implemented in various ways, such as a groove structure, a retaining ring, or a snap fastener. For example, in one embodiment, at least one of the first mounting portion 11600 and the second mounting portion 11700 is configured to use an insertion groove. The structure of the insertion groove can be constructed according to the end face shape formed by the combination of the frame substrate 11310 and the two frame uprights 11320. In this case, the first mounting portion 11600 is located on the side surface of the frame partition 11200 facing the frame base 11100, and the second mounting portion 11700 is located on the side surface of the frame base 11100 facing the frame partition 11200. Therefore, the top ends of the frame base plate 11310 and the two frame uprights 11320 are configured to be simultaneously inserted into the first mounting portion 11600, and the bottom ends of the frame base plate 11310 and the two frame uprights 11320 are configured to be simultaneously inserted into the second mounting portion 11700, and both frame uprights 11320 are fixedly connected to the column assembly 11400. For example, the first mounting portion 11600 and the second mounting portion 11700 may adopt an "I"-shaped groove structure that matches the combination of the frame base plate 11310 and the two frame uprights 11320.

[0073] The column assembly 11400 can be composed of several column structures. For example, in one embodiment, the column assembly 11400 includes two frame columns 11410, which are vertically mounted on the frame base 11100. The column assembly 11400 may also include at least two locking kits 11420, which can be fixedly fitted onto the frame columns 11410 by means of snap-fit, threaded connection, etc. In this case, each frame column 11410 is fitted with at least one locking kit 11420, and each frame plate 11320 is provided with at least one locking part 11800. Therefore, when each frame plate 11320 is matched and connected to one frame column 11410, each frame plate 11320 can be fixedly connected to the locking kit 11420 of the frame column 11410 through the locking part 11800.

[0074] This application provides a testing system, which includes a test bench, a driver, a controller, and a host computer. The driver is connected to the test bench, the controller is connected to at least one of the test bench and the driver, and the host computer is connected to at least one of the test bench, the driver, and the controller. Since the specific structure, functional principle, and technical effects of the aforementioned balancing mechanism 40000 and the test bench have been described in detail above, they will not be repeated here. Any technical details regarding the aforementioned balancing mechanism 40000 and the test bench can be found in the foregoing description.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
