[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] See Figures 1 to 12 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 set based on the assembly requirements of the power mechanism 20000, guide mechanism 30000, and balancing mechanism 40000. The assembly frame 10000 needs to be configured to define a linear motion trajectory, which is used to define the movement of the power mechanism 20000.

[0080] In one embodiment, the power mechanism 20000 includes a power source and a motion component 21000. The power source is mounted on the assembly frame 10000, and the motion component 21000 is movably mounted on the assembly frame 10000 along a motion trajectory. The power source and the motion component 21000 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 21000. Thus, the power source can drive the motion component 21000 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 21000 is connected to the damper, the motion of the motion component 21000 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.

[0081] During the damper operation test performed by the aforementioned motion component 21000, the guide mechanism 30000 further provides guiding assistance to the motion component 21000, and the balancing mechanism 40000 further provides balancing assistance to the motion component 21000. 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 21000 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.

[0082] The guiding aid is mainly used to ensure that the motion component 21000 moves accurately along the motion trajectory during high-speed motion, and to prevent the motion component 21000 from deviating when the motion speed is too high. The balancing mechanism 40000 is mainly used to ensure that the motion component 21000 maintains stability during high-speed motion, and to prevent the motion component 21000 from becoming unstable relative to the assembly frame 10000 when the motion speed is too high, which would lead to deviation of motion.

[0083] Therefore, the guiding and balancing assistance provided to the power mechanism 20000 by the guide mechanism 30000 and the balancing mechanism 40000 ensures that both the motion component 21000 and the damper maintain high precision and stability during motion testing of the damper. Even when the motion component 21000 increases its speed, it can effectively test the damper's operating conditions. Given the rapid development of CDC dampers, the continuously adjustable and fast-adjusting characteristics of CDC dampers provide stable testing conditions, meeting the higher testing requirements of CDC dampers.

[0084] 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.

[0085] 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 component 21000 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.

[0086] 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.

[0087] 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 21000 of the power mechanism 20000 reciprocates along the motion trajectory, it actually moves between the frame partition 11200 and the frame base 11100.

[0088] 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 motion assembly 21000 moves at high speed along the motion trajectory, the impact force applied along the motion 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 motion assembly 21000 moves at high speed.

[0089] 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.

[0090] 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 21000 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 driven by the motion component 21000, allowing the damper to be controlled to move within the second frame unit. 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.

[0091] In one embodiment, the outer protective cover 12000 includes a first unit cover 12100 and a second unit cover 12200, which together constitute the outer protective cover 12000. The first unit cover 12100 is mounted between the frame partition 11200 and the frame base 11100, and its inner cavity 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, and its inner cavity 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.

[0092] 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.

[0093] 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.

[0094] The frame base plate 11310 and two frame uprights 11320 are configured as guide mechanisms 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, so that the motion component 21000 of the power mechanism 20000 can move within the motion clearance holes 11311. That is, the motion clearance holes 11311 can be configured to allow the motion component 21000 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 component 21000 within them. The purpose of the motion avoidance hole 11311 is twofold: first, to accommodate the movement of the motion component 21000; and second, to limit the movement range of the motion component 21000 within the motion avoidance hole 11311, thus also serving as a safety limit to prevent the motion component 21000 from detaching from the motion avoidance hole 11311 due to high-speed movement, thereby improving the safety and stability of the movement.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] Regarding the aforementioned power mechanism 20000, the motion component 21000 of the power mechanism 20000 can adopt various structures, mainly for facilitating the installation of the damper. In one embodiment, the motion component 21000 may include a motion base 21100 and an output component 21200. The motion base 21100 is movably mounted on the assembly frame 10000 along a motion trajectory. The power source is driven by the motion base 21100, and at this time, the power source is used to drive the motion base 21100 to reciprocate relative to the assembly frame 10000 along the motion trajectory at a preset motion speed. The output component 21200 is mounted on the motion base 21100 and is configured to be connected to the damper. Therefore, when the power source drives the motion component 21000 to reciprocate relative to the assembly frame 10000 along the motion trajectory at a preset motion speed, the motion of the motion component 21000 can synchronously drive the output component 21200 and the damper to move at the same speed. The output component 21200 can be configured as a structure that facilitates the connection or installation of the damper, such as a column, etc., without limitation.

[0099] In one embodiment, the motion base 21100 includes a main motion base 21110 and a combined motion plate 21120. The main motion base 21110 has at least two main base sidewalls facing different directions. Several main base sidewalls are arranged around the main motion base 21110 circumferentially. For example, the main motion base 21110 has two main base sidewalls facing opposite directions, i.e., the two main base sidewalls are located on opposite sides of the main motion base 21110. The top wall of the main base 21110 is provided with an output mounting position, and an output component 21200 is assembled to the output mounting position of the main motion base 21110. When the output component 21200 is a column, it can be vertically assembled to the output mounting position of the main motion base 21110. For example, the output component 21200 can be directly and vertically connected to the output mounting position of the main motion base 21110, or it can be indirectly assembled to the output mounting position of the main motion base 21110 via a pad, block, or the like.

[0100] The combined motion plate 21120 includes at least two motion plate components 21121. The number of motion plate components 21121 is the same as the number of main body sidewalls of the main motion seat 21110. For example, the combined motion plate 21120 has two motion plate components 21121, and the two motion plate components 21121 are matched with the two main body sidewalls of the main motion seat 21110. At this time, each motion plate component 21121 is assembled and connected to a matching main body sidewall of the main motion seat 21110, and the plane of each motion plate component 21121 is parallel to the motion trajectory. Among them, several moving plates 21121 are movably assembled on the assembly frame 10000 along the motion trajectory. The power source is driven and cooperated with at least one of the main moving seat 21110 and the combined moving plate 21120. For example, the power source is connected to the combined moving plate 21120, and then indirectly connected to the main moving seat 21110 through the combined moving plate 21120, thereby driving the main moving seat 21110 to reciprocate relative to the assembly frame 10000 along the motion trajectory at a preset motion speed.

[0101] In one embodiment, the motion base 21100 further includes sliding transmission members 33000. The number of sliding transmission members 33000 is the same as the number of motion plates 21121. Each sliding transmission member 33000 includes a connecting portion 4201033100 and a sliding portion 33200 that are interconnected. The connecting portion 4201033100 and the sliding portion 33200 can be configured with different shapes as needed, such as plate-shaped, column-shaped, spherical, etc., which are not limited here. Each sliding transmission member 33000 is fixedly connected to a matching motion plate 21121 based on its connecting portion 4201033100, and each sliding transmission member 33000 is movably assembled to the assembly frame 10000 based on its sliding portion 33200. Therefore, each motion plate 21121 can be movably assembled to the assembly frame 10000 along a motion trajectory via a matching sliding transmission member 33000.

[0102] In one embodiment, the connecting portion 4201033100 of the sliding transmission member 33000 is configured as a straight column, such as a cylinder or prism. In this case, a positioning groove 21122 can be provided on the outer surface of the moving plate 21121. The shape and size of the positioning groove 21122 can be adapted to the connecting portion 4201033100 of the sliding transmission member 33000. For example, the positioning groove 21122 is a straight groove along the longitudinal direction of the moving plate 21121. The positioning groove 21122 has a groove top wall and The two sidewalls of the groove are connected to the top wall of the groove. At this time, the top wall of the positioning groove 21122 is located at the top of the positioning groove 21122, and the bottom of the positioning groove 21122 has a through groove. This makes the positioning groove 21122 open in the longitudinal direction, forming a groove structure that is enclosed on three sides and open on one side, rather than a groove structure that is enclosed on all four sides in the conventional case. The connecting part 4201033100 of the sliding transmission member 33000 is configured to be assembled in the positioning groove 21122 along the longitudinal direction of the moving plate 21121.

[0103] Because the positioning groove 21122 forms a groove structure that is enclosed on three sides and open on one side, the top of the connecting part 4201033100 can mutually limit and abut against the top wall of the positioning groove 21122. During the movement of the sliding transmission member 33000 relative to the assembly frame 10000 based on its sliding part 33200, as the sliding transmission member 33000 moves towards the top along its movement trajectory, the top of the connecting part 4201033100 can be pressed more tightly against the top wall of the positioning groove 21122, thereby ensuring… The sliding transmission component 33000 and the moving plate 21121 maintain absolute synchronous movement when moving towards the top. Even when the movement speed is high, the acceleration is large, and the force between them is also large, the mutual limiting contact between the top of the connecting part 4201033100 and the top wall of the positioning groove 21122 can ensure that the sliding transmission component 33000 and the moving plate 21121 maintain absolute synchronous movement when moving towards the top, thereby providing superior test conditions and meeting the higher test requirements of the CDC damper.

[0104] In addition to the main motion seat 21110, in one embodiment, the motion base 21100 also includes an auxiliary motion seat 21130. The auxiliary motion seat 21130 has at least two auxiliary seat sidewalls facing different directions. A plurality of auxiliary seat sidewalls are arranged around the main motion seat 21110 in a circumferential manner. For example, the auxiliary motion seat 21130 has two auxiliary seat sidewalls facing opposite directions, that is, the two auxiliary seat sidewalls are located on opposite sides of the auxiliary motion seat 21130. Each auxiliary seat sidewall of the auxiliary motion seat 21130 is parallel to and in the same plane as a matching main seat sidewall of the main motion seat 21110.

[0105] Each moving plate 21121 has a first engaging portion 21123 and a second engaging portion 21124 on its inner side surface. Each main body sidewall of the main moving seat 21110 is engaged with the first engaging portion 21123 of a matching moving plate 21121, and each auxiliary sidewall of the auxiliary moving seat 21130 is engaged with the second engaging portion 21124 of a matching moving plate 21121. For example, both moving plates 21121 have a first engaging portion 21123 and a second engaging portion 21124 on their inner side surfaces. The two main body sidewalls of the main moving seat 21110 are engaged with the first engaging portions 21123 of the two moving plates 21121, and the two auxiliary sidewalls of the auxiliary moving seat 21130 are engaged with the second engaging portions 21124 of the two moving plates 21121, respectively.

[0106] In one embodiment, the first snap-fit ​​portion 21123 is configured as a first snap-fit ​​groove, the first snap-fit ​​groove having a groove top wall and a groove bottom wall that are opposite each other along the longitudinal direction of the moving plate 21121, and the first snap-fit ​​groove having two through slots that are opposite each other along the transverse direction of the moving plate 21121, the main moving seat 21110 is snap-fitted into the first snap-fit ​​groove, and the top of the main moving seat 21110 is in limiting contact with the groove top wall of the first snap-fit ​​groove, and the bottom of the main moving seat 21110 is in limiting contact with the groove bottom wall of the first snap-fit ​​groove.

[0107] The second snap-fit ​​portion 21124 is configured as a second snap-fit ​​groove. The second snap-fit ​​groove has a groove top wall and a groove bottom wall that are opposite each other along the longitudinal direction of the moving plate 21121. The second snap-fit ​​groove also has two through slots that are opposite each other along the transverse direction of the moving plate 21121. The auxiliary motion seat 21130 is snap-fitted into the second snap-fit ​​groove. The top of the auxiliary motion seat 21130 is in limiting contact with the groove top wall of the second snap-fit ​​groove, and the bottom of the auxiliary motion seat 21130 is in limiting contact with the groove bottom wall of the second snap-fit ​​groove.

[0108] Therefore, during the movement of the several moving plates 21121 relative to the assembly frame 10000 based on the sliding transmission member 33000, when the several moving plates 21121 move towards the top along the movement trajectory, the top of the main moving seat 21110 and the top wall of the first locking groove will press against each other more tightly. This ensures that the main moving seat 21110 and the moving plates 21121 maintain absolute synchronous movement when moving towards the top. Even when the movement speed is very high, the acceleration is very large, and the force between the two is also very large, the mutual limiting contact between the top of the main moving seat 21110 and the top wall of the first locking groove can still ensure that the main moving seat 21110 and the moving plates 21121 maintain absolute synchronous movement when moving towards the top, thereby providing superior test conditions and meeting the above-mentioned higher test requirements of the CDC damper.

[0109] Similarly, when several moving plates 21121 move towards the top along the movement trajectory, the top of the auxiliary moving seat 21130 and the top wall of the second locking groove will press against each other more tightly, thereby ensuring that the auxiliary moving seat 21130 and the moving plates 21121 maintain absolute synchronous movement when moving towards the top. Even when the movement speed is very high, the acceleration is very large, and the force between the two is also very large, the mutual limiting contact between the top of the auxiliary moving seat 21130 and the top wall of the second locking groove can still ensure that the auxiliary moving seat 21130 and the moving plates 21121 maintain absolute synchronous movement when moving towards the top.

[0110] Similarly, when several moving plates 21121 move towards the bottom along the movement trajectory, the bottom of the main moving seat 21110 and the bottom wall of the first locking groove will press against each other more tightly, thereby ensuring that the main moving seat 21110 and the moving plates 21121 maintain absolute synchronous movement when moving towards the bottom. Even when the movement speed is very high, the acceleration is very large, and the force between the two is also very large, the mutual limiting contact between the bottom of the main moving seat 21110 and the bottom wall of the first locking groove can still ensure that the main moving seat 21110 and the moving plates 21121 maintain absolute synchronous movement when moving towards the bottom.

[0111] Meanwhile, as several moving plates 21121 move towards the bottom along the movement trajectory, the bottom of the auxiliary moving seat 21130 and the bottom wall of the second locking groove will press against each other more tightly, thereby ensuring that the auxiliary moving seat 21130 and the moving plates 21121 maintain absolute synchronous movement when moving towards the bottom. Even when the movement speed is very high, the acceleration is very large, and the force between the two is also very large, the mutual limiting contact between the bottom of the auxiliary moving seat 21130 and the bottom wall of the second locking groove can still ensure that the auxiliary moving seat 21130 and the moving plates 21121 maintain absolute synchronous movement when moving towards the bottom.

[0112] In one embodiment, the motion plate 21121 may include a middle plate 21125, a top plate 21126, and a bottom plate 21127. These three parts constitute the motion plate 21121 and can be integrally formed to constitute the motion plate 21121. The top plate 21126 is connected to the top of the middle plate 21125, and a first engaging portion 21123 is provided on the top plate 21126. The top plate 21126 is configured to connect to the side wall of the main body seat 21110 via the first engaging portion 21123. The bottom plate 21127 is connected to the bottom of the middle plate 21125, and the second snap-fit ​​part 21124 is provided on the bottom plate 21127. The bottom plate 21127 is configured to be connected to the auxiliary seat side wall of the auxiliary motion seat 21130 via the second snap-fit ​​part 21124.

[0113] In one embodiment, the guide mechanism 30000 includes at least one guide post 31000. For example, two guide posts 31000 that cooperate with each other in parallel are provided. The guide posts 31000 are straight posts and are configured to form a guide trajectory. Therefore, the main motion seat 21110 and the auxiliary motion seat 21130 may be provided with guide holes 21140, and all guide posts 31000 are movably inserted into the guide holes 21140.

[0114] Each guide hole 21140 can be fitted with a floating bushing, and the guide post 31000 is movably inserted into the floating bushing within the guide hole 21140. Based on the indirect assembly of the floating bushing between the guide post 31000 and the guide hole 21140, the friction force is greatly reduced when the guide post 31000 reciprocates relative to the guide hole 21140. Therefore, when the main motion seat 21110 and the auxiliary motion seat 21130 reciprocate along the motion trajectory, the motion speed can be increased due to the greatly reduced friction force. The guide post 31000 can ensure that the main motion seat 21110 and the auxiliary motion seat 21130 reciprocate accurately along the motion trajectory and the guide trajectory based on the formed guide trajectory, thereby providing stable and accurate test conditions.

[0115] Regarding the aforementioned guiding mechanism 30000, in one embodiment, the guiding mechanism 30000 may include a guiding base 32000 and a sliding transmission member 33000. The guiding base 32000 includes at least two unit bases 32100, for example, two unit bases 32100 are provided. Each unit base 32100 is provided with a guide groove 32110, and the openings of the guide grooves 32110 of the unit bases 32100 are arranged facing each other. The guide grooves 32110 of the unit bases 32100 are configured to jointly form a guiding trajectory. The guiding trajectory is a straight trajectory and is configured to guide the reciprocating motion of the power mechanism 20000 of the test bench, that is, to guide the motion component 21000 in the power mechanism 20000 to reciprocate along the guiding trajectory and the motion trajectory.

[0116] The sliding transmission component 33000 includes a connecting part 4201033100 and a sliding part 33200 that are connected to each other. The connecting part 4201033100 and the sliding part 33200 can be set to different shapes as required, such as plate-shaped, column-shaped, spherical, etc., which are not limited here. The number of sliding transmission members 33000 is configured to be the same as the number of unit bases 32100 of the guide base 32000. The sliding part 33200 of each sliding transmission member 33000 is slidably assembled with a matching guide groove 32110 of the guide base 32000, thereby allowing the sliding transmission member 33000 to reciprocate relative to the guide base 32000 along the guide trajectory. The connecting parts 42010 and 33100 of several sliding transmission members 33000 are configured to jointly connect the power mechanism 20000 of the test bench, that is, the motion component 21000 is connected to the connecting part 42010 and 33100 of the guide mechanism 30000, thereby being movably assembled relative to the guide mechanism 30000 along the guide trajectory.

[0117] Therefore, the aforementioned sliding transmission component 33000 reciprocates relative to the guide base 32000 along the guide trajectory, forming a guiding aid to ensure that the motion component 21000 accurately reciprocates along the motion trajectory during high-speed movement, preventing deviation from the motion when the motion component 21000's speed is too high. When the motion component 21000 increases its speed, the damper is effectively tested under operating conditions. Given the rapid development of CDC dampers, stable testing conditions are provided for the continuously adjustable and fast-adjusting characteristics of CDC dampers, meeting the higher testing requirements of CDC dampers.

[0118] The reciprocating motion of the sliding transmission member 33000 relative to the guide base 32000 can be achieved in various ways. For example, in one embodiment, the sliding part 33200 includes a connected sliding segment 33210 and a limiting segment 33220. The sliding segment 33210 and the limiting segment 33220 are two segments of the entire sliding part 33200. The sliding segment 33210 and the limiting segment 33220 together constitute the sliding part 33200. The sliding segment 33210 and the limiting segment 33220 can be integrally molded. However, different segments are separated in the sliding part 33200 according to specific requirements to serve as the sliding segment 33210 and the limiting segment 33220. At this time, the connecting part 4201033100 is connected to the sliding segment 33210 of the sliding part 33200, while the limiting segment 33220 of the sliding part 33200 is indirectly connected to the connecting part 4201033100 through the sliding segment 33210, and the distance between the sliding segment 33210 and the connecting part 4201033100 is less than the distance between the limiting segment 33220 and the connecting part 4201033100.

[0119] Correspondingly, the guide groove 32110 includes a connected sliding groove segment 32111 and a limiting groove segment 32112. The sliding groove segment 32111 and the limiting groove segment 32112 are two spatial portions of the entire guide groove 32110, and together they constitute the guide groove 32110. At this time, the sliding segment 33210 of the sliding part 33200 is slidably assembled in the sliding groove segment 32111 of the guide groove 32110 along the guide trajectory, and the limiting segment 33220 of the sliding part 33200 is slidably assembled in the limiting groove segment 32112 of the guide groove 32110 along the guide trajectory. The limiting groove segment 32112 is configured to prevent the limiting segment 33220 from moving in any direction other than the guide trajectory.

[0120] The aforementioned prohibition effect prevents the limiting segment 33220 from laterally disengaging from the limiting groove segment 32112, thereby ensuring that the entire sliding part 33200 slides and assembles only along the guide trajectory within the guide groove 32110. During the sliding process, regardless of whether the sliding part 33200 is subjected to a force deviating from the guide trajectory, it will not deviate from the guide trajectory. Therefore, during high-speed movement, the stability of the assembly between the sliding part 33200 and the guide groove 32110 is maintained. Even when the moving component 21000 is in high-speed movement, it can provide stable and precise guidance for the high-speed movement of the moving component 21000, ensuring that the moving component 21000 moves at high speed only along the movement trajectory and the guide trajectory.

[0121] Regarding the implementation of the aforementioned prohibition effect, in one embodiment, the width of the sliding groove segment 32111 can be limited to be less than the width of the limiting groove segment 32112, and the width of the sliding segment 33210 can be less than the width of the limiting segment 33220. Furthermore, the width of the limiting segment 33220 is greater than the width of the sliding groove segment 32111, ensuring that the limiting segment 33220 can only slide along the guide trajectory within the limiting groove segment 32112, and cannot deviate from the guide trajectory. Thus, through the size matching design of the limiting segment 33220 and the sliding groove segment 32111, the limiting segment 33220 is prevented from detaching from the limiting groove segment 32112, thereby preventing the limiting segment 33220 from moving in directions deviating from the guide trajectory.

[0122] In one embodiment, the sliding portion 33200 of the sliding transmission member 33000 is configured as a plate-shaped component, and the guide groove 32110 is a plate-shaped groove. Furthermore, a sliding guide disc 32120 is provided inside the guide groove 32110. The sliding guide disc 32120 can be circular, square, or other disc shapes. Two sliding guide discs 32120 are configured. In this case, the guide groove 32110 has two inner sidewalls facing opposite directions. The two sliding guide discs 32120 are symmetrically arranged on the two opposite inner sidewalls of the guide groove 32110, and the space between the two sliding guide discs 32120 forms the sliding groove segment 32111. Since the two sliding guide discs 32120 are assembled in the guide groove 32110, they occupy part of the space in the guide groove 32110. However, there is another part of the space in the guide groove 32110 that is not occupied by the two sliding guide discs 32120. At this time, the other part of the space in the guide groove 32110 that is not occupied by the two sliding guide discs 32120 can be used to form the limiting groove segment 32112. Thus, by assembling the sliding guide discs 32120 in the guide groove 32110, the sliding groove segment 32111 and the limiting groove segment 32112 are distinguished in the guide groove 32110. The limiting groove segment 32112 is located inside the sliding groove segment 32111 in the guide groove 32110.

[0123] Regarding the implementation of the sliding section 33210 of the sliding part 33200 sliding along the guide trajectory and slidably assembled in the sliding groove section 32111 of the guide groove 32110, in one embodiment, the sliding guide disk 32120 includes an inner disk surface and an outer disk surface facing opposite directions. The inner disk surfaces of the two sliding guide disks 32120 face each other, and the outer disk surfaces of the two sliding guide disks 32120 are fixedly connected to the two opposite inner sidewalls of the guide groove 32110, for example, by means of snap-fit ​​connection, threaded connection, etc.

[0124] At this time, each of the two opposing inner sidewalls of the guide groove 32110 is provided with a positioning unit portion 32130, and the outer surface of the sliding guide disk 32120 is provided with a docking unit portion 32140 for positioning and engaging with the positioning unit portion 32130. The positioning unit portion 32130 and the docking unit portion 32140 can adopt various structures to achieve engagement, thereby enabling the sliding guide disk 32120 to be positioned and assembled with the positioning unit portion 32130 in the guide groove 32110 through the docking unit portion 32140. For example, in one embodiment, the positioning unit portion 32130 includes at least one of a groove structure and a protrusion structure.

[0125] Regarding the structural design of the groove structure and the protrusion structure, in one embodiment, the positioning unit 32130 includes a first guide protrusion 32131 and a second guide protrusion 32132. Both the first guide protrusion 32131 and the second guide protrusion 32132 are configured as straight protrusions parallel to the guide trajectory. The sliding guide disk 32120 is positioned and assembled between the first guide protrusion 32131 and the second guide protrusion 32132, which is equivalent to limiting the sliding guide disk 32120 between the first guide protrusion 32131 and the second guide protrusion 32132. This causes the two sides of the sliding guide disk 32120 to make limiting contact with the first guide protrusion 32131 and the first guide protrusion 32131 respectively, prohibiting movement along the direction from the first guide protrusion 32131 to the second guide protrusion 32132 or from the second guide protrusion 32132 to the first guide protrusion 32131, which is equivalent to prohibiting lateral movement.

[0126] Among them, the two sides of the sliding guide disk 32120 are the outer end and inner end of the sliding segment 33210. When the sliding guide disk 32120 is positioned and assembled along the first guide protrusion 32131 and the first guide protrusion 32131, the first guide protrusion 32131 and the first guide protrusion 32131 limit the contact between the outer end and the inner end of the sliding guide disk 32120. It also has the effect of restricting the sliding segment 33210 from laterally disengaging from the first guide protrusion 32131 and the second guide protrusion 32132. Therefore, during the high-speed movement, the stability of the assembly between the sliding guide disk 32120 and the guide groove 32110 is maintained. Even when the motion component 21000 is in the process of high-speed movement, it can provide stable and accurate guidance for the high-speed movement of the motion component 21000, ensuring that the motion component 21000 only moves at high speed along the motion trajectory and the guide trajectory.

[0127] In addition, to enhance the aforementioned limiting effect, in one embodiment, the positioning unit 32130 may further include a third guide protrusion 32133, which is located between the first guide protrusion 32131 and the second guide protrusion 32132. The docking unit 32140 includes a docking guide groove 32141, and the sliding guide disk 32120 is slidably assembled with the third guide protrusion 32133 through the docking guide groove 32141. The third guide protrusion 32133 extends parallel to the guide trajectory, and its width is greater than the width of at least one of the first guide protrusion 32131 and the second guide protrusion 32132. The positioning and fitting assembly between the docking guide groove 32141 and the third guide protrusion 32133 can also maintain the stability of the assembly between the sliding part 33200 and the guide groove 32110. Even when the motion component 21000 is in high-speed motion, it can provide stable and precise guidance for the high-speed motion of the motion component 21000, ensuring that the motion component 21000 moves at high speed only along the motion trajectory and the guide trajectory.

[0128] Regarding the aforementioned balancing mechanism 40000, in one embodiment, the balancing mechanism 40000 includes a balancing base 41000 and a balancing frame 42000. The number of balancing bases 41000 is configured to be several, all distributed along a preset annular distribution trajectory. Each balancing base 41000 has an mounting surface on its top, and all mounting surfaces of the balancing bases 41000 are in the same plane. Therefore, the several balancing bases 41000 can cooperate with each other, and each balancing base 41000 can provide a balancing base point in the overall balancing mechanism 40000. Utilizing the balancing base points formed by the different positions of the several balancing bases 41000 in the annular distribution trajectory, a ring-shaped balancing assembly structure is ultimately formed along the annular distribution trajectory.

[0129] It should be noted that the ring-shaped balance combination structure is not a continuous ring, but rather a discontinuous ring-shaped balance combination structure formed by the number and distribution density of the balance bases 41000 in the ring distribution trajectory. The purpose is to adjust the number, distribution density, and distribution method of the balance bases 41000 according to actual support requirements, so as to form a targeted and stable balance support force. This ensures that the moving component 21000 is provided with stable balance support during high-speed movement, and prevents the assembly of the moving component 21000 relative to the assembly frame 10000 from becoming unstable when the movement speed of the moving component 21000 is too high, which would lead to deviation in movement.

[0130] The number of balancing frames 42000 is configured to be several. The function of the balancing frames 42000 is to connect the aforementioned balancing bases 41000, so that each independent balancing base 41000 can be connected by the balancing frames 42000 to form one or more relatively stable integral structures. For example, each balancing frame 42000 is connected to at least two balancing bases 41000, wherein each balancing frame 42000 includes at least two connected connecting portions 4201033100 and at least one recess. The recess 42020 is a groove structure that can be used to avoid the movement of the motion component 21000. That is, the motion component 21000 can enter and exit the recess 42020 during high-speed reciprocating motion. The connecting portion 4201033100 of the balance frame 42000 is configured to connect with the mounting top surface of the balance base 41000. Each recess 42020 of the balance frame 42000 is located between two adjacent balance bases 41000. Therefore, a portion of the structure of the motion component 21000 can move between adjacent balance bases 41000, thereby forming balanced support on different sides of the motion component 21000 through adjacent balance bases 41000, ensuring a balanced effect during movement.

[0131] In one embodiment, the balancing mechanism 40000 may include a balancing pad 43000 or a support element 44000, etc. The number of balancing pads 43000 is configured to be plurality, each balancing pad 43000 being configured to be fitted into a matching recess 42020 of the balancing frame 42000. The side of the balancing pad 43000 is in force-supported contact with the inner wall of the recess 42020, thereby providing force support to the overall frame structure of the balancing frame 42000. This prevents the large impact force exerted on the balancing frame 42000 during high-speed movement of the moving component 21000 from causing deformation of the balancing frame 42000, and avoids the balancing frame 42000 from reducing the stability of the balancing support due to deformation. The number of support elements 44000 is configured to be several, with one support element 44000 provided on the mounting top surface of each balance base 41000. Each connection part 4201033100 of the balance frame 42000 is connected to the mounting top surface of the balance base 41000 through the support element 44000. The support element 44000 can be assembled from components such as bolts and nuts, with the purpose of stably connecting the balance frame 42000 and the balance base 41000.

[0132] The number and arrangement of the balancing bases 41000 and the balancing frames 42000 can be set according to actual conditions. For example, in one embodiment, the number of balancing bases 41000 is even, and the number of balancing bases 41000 is configured to be at least two pairs. Each pair of balancing bases 41000 is matched and connected to a balancing frame 42000. Each balancing frame 42000 has two connecting portions 4201033100 located at both ends and a recess 42020 located between the two connecting portions 4201033100. The two connecting portions 4201033100 of each balancing frame 42000 are connected to the two mounting top surfaces of each pair of balancing bases 41000.

[0133] The circular distribution trajectory can be configured as a square circular trajectory, which is equivalent to a circular trajectory formed along the edge of a square. Therefore, the square circular trajectory has four vertex portions. The number of balance bases 41000 is configured to be four, and the four balance bases 41000 are respectively set at the four vertex portions of the square circular trajectory. The number of balance frames 42000 is configured to be two, and the two connecting portions 4201033100 of each balance frame 42000 are connected to the two mounting top surfaces of the same pair of balance bases 41000.

[0134] In one embodiment, the balance frame 42000 includes a connecting plate 42100 and a curved panel 42200. At least a portion of the plate area of ​​the connecting plate 42100 is configured to form a connecting portion 4201033100, wherein two connecting plates 42100 are configured. At the same time, at least a portion of the plate area of ​​the curved panel 42200 has a recessed curved surface, and the curved surface of the curved panel 42200 is configured to form a recess 42020. Both ends of the curved panel 42200 are respectively connected to the two connecting plates 42100. Therefore, a complete balance frame 42000 can be constituted by one curved panel 42200 and two connecting plates 42100.

[0135] The curved panel 42200 can be configured as a U-shape or similar structure, thereby forming a recess 42020 in the middle of the curved panel 42200. In one embodiment, the curved panel 42200 may include a base plate 42210 and two upright plates 42220. The two ends of the base plate 42210 are respectively connected to one end of the two upright plates 42220, and each upright plate 42220 is inclined relative to the base plate 42210. The angle of the inclined connection can be set to 60 degrees. An angle between 60° and 120°, for example, 90° or about 90°, is used to form a recess 42020 by the inclined connection of the base plate 42210 and the two upright plates 42220. The other ends of the two upright plates 42220 are respectively connected to the two connecting plates 42100, and each upright plate 42220 is inclined relative to the connecting plate 42100. The angle of the inclined connection can be set between 60° and 120°, for example, 90° or about 90°.

[0136] The connecting plate 42100 and the curved panel 42200 are configured as a single-piece structure, or the base plate 42210 and the two upright plates 42220 can also be configured as a single-piece structure, so that each balancing frame 42000 can be configured as a single-piece structure. A reinforcing corner plate 42230 may also be provided between the curved panel 42200 and the connecting plate 42100.

[0137] In one embodiment, the balancing base 41000 includes a balancing column 41100, a balancing top seat 41200, a balancing base 41300, and a stabilizing base plate 41400. The stabilizing base plate 41400 serves as the assembly base for the balancing column 41100, the balancing top seat 41200, and the balancing base 41300. The balancing top seat 41200 is assembled on the top of the balancing column 41100, and the top of the balancing top seat 41200 is configured to form an assembly top surface. The balancing base 41300 is assembled on the balancing column 41100. At the bottom of 00, the stable base plate 41400 is configured as an assembly frame 10000 for mounting on the test bench. The cross-sectional area of ​​the stable base plate 41400 is larger than that of the balance base 41300. The balance base 41300 is mounted on the stable base plate 41400. Based on its larger cross-sectional area, the stable base plate 41400 provides a more stable assembly foundation for the balance column 41100, the balance top seat 41200, and the balance base 41300, so that the entire balance base 41000 has a stable overall structure.

[0138] In addition, in one embodiment, the balancing base 41000 may further include balancing uprights 41500. The number of balancing uprights 41500 is configured to be several, all parallel to the balancing column 41100, and arranged around the balancing column 41100 circumferentially. The top end of each balancing upright 41500 is inserted into the balancing top seat 41200, and the bottom end of each balancing upright 41500 is inserted into the balancing base 41300. The ratio of the diameter of the balancing column 41100 to the diameter of the balancing upright 41500 is between 5 and 15, meaning the balancing upright 41500 is thinner than the balancing column 41100.

[0139] Since several balance pillars 41500 are arranged around the balance column 41100, the assembly of the balance top seat 41200 and the balance base 41300 can be further reinforced around the balance column 41100. During the high-speed movement of the motion component 21000, the motion component 21000 may exert a large impact force on the balance frame 42000 and different balance bases 41000. To avoid damage to the balance column 41100 and the balance base 41000, further reinforcement is needed. The balance top 41200, balance base 41300, and stable base plate 41400 maintain a stable assembly state even under large impact forces. Several circumferentially distributed balance rods 41500 can provide force support to the balance top 41200 and balance base 41300 at different circumferential positions of the balance column 41100, ensuring that all components of the balance base 41000 have a stable assembly state. This ensures that the high-speed movement of the motion component 21000 can provide the damper with the high-demand test conditions.
