[0079] See also Figures 1 to 12 As shown, the present 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 basis of the power mechanism 20000, the guide mechanism 30000 and the balancing mechanism 40000, and the specific size and structure of the assembly frame 10000 can be set based on the assembly requirements of the power mechanism 20000, the guide mechanism 30000 and the balancing mechanism 40000. Among them, the assembly frame 10000 needs to be configured to define a motion trajectory, the motion trajectory is a straight line trajectory, and the motion trajectory is used to define the motion mode of the power mechanism 20000.

[0080] In one embodiment, the power mechanism 20000 includes a power source and a motion component 21000, wherein the power source is assembled on the assembly frame 10000, and the motion component 21000 is assembled on the assembly frame 10000 along a motion trajectory. The power source and the motion component 21000 are driven and cooperated, wherein the power source can adopt different types of power forms such as electromagnetic power, mechanical power, etc. The power source provides an energy source for the movement of the motion component 21000, thereby the power source can be used to drive the motion component 21000 to reciprocate relative to the assembly frame 10000 along the motion trajectory at a preset motion speed, and the motion speed can be adjusted according to actual needs, thereby when the motion component 21000 is connected to the damper, the movement of the motion component 21000 can synchronously drive the damper to move at the same speed, and in this way, the damper is controlled to simulate work and the working condition of the damper is tested.

[0081] During the working condition test of the damper by the motion assembly 21000, the guide mechanism 30000 further provides guide assistance to the motion assembly 21000, and the balancing mechanism 40000 further provides balancing assistance to the motion assembly 21000. The guide mechanism 30000 is assembled on the assembly frame 10000, and the guide mechanism 30000 is configured to form a guide track, which is a straight track, and the guide track is parallel to the motion track. The motion assembly 21000 is assembled relative to the guide mechanism 30000 along the guide track. The balancing mechanism 40000 is assembled on the assembly frame 10000, and at least one of the guide mechanism 30000 and the power mechanism 20000 is assembled on the balancing mechanism 40000.

[0082] The guiding aid is mainly used to ensure that the moving component 21000 accurately reciprocates along the motion trajectory during high-speed motion, and to prevent the moving component 21000 from deviating from the motion when the moving speed is too high. The balancing mechanism 40000 is mainly used to ensure that the moving component 21000 maintains stability during high-speed motion, and to prevent the moving component 21000 from being assembled unstably relative to the assembly frame 10000 when the moving speed is too high, thereby causing the moving component 21000 to deviate from the motion.

[0083] It can be seen that based on the guidance assistance and balancing assistance provided by the guide mechanism 30000 and the balancing mechanism 40000 to the power mechanism 20000, it can ensure that the motion component 21000 of the power mechanism 20000 can maintain high precision and high stability of the motion when driving the damper for motion testing. When the motion component 21000 increases the motion speed, the damper can also be effectively tested for working conditions. Under the background of the rapid development of CDC dampers, the damping of CDC dampers is continuously adjustable and has a fast adjustment speed. Provide stable test conditions to meet the higher test requirements required by CDC dampers.

[0084] Regarding the assembly frame 10000 mentioned above, in one embodiment, the assembly frame 10000 includes a frame body 11000 and an outer shield body 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 on the frame base 11100 through the column assembly 11400, so that a space area of ​​a certain height is formed between the frame partition 11200 and the frame base 11100, and at this time, the frame assembly 11300 can be assembled in the space area 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 to be used for assembling at least one of the power mechanism 20000, the guide mechanism 30000 and the balance 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 to ensure that the moving component 21000 of the power mechanism 20000 will apply a large impact force to the frame body 11000 during high-speed movement. However, the frame partition 11200, the frame base 11100 and the frame assembly 11300 in the frame body 11000 can also resist the above-mentioned large impact force based on a more stable assembly structure, thereby providing stable testing conditions to meet the higher testing requirements required for the CDC damper.

[0086] In one embodiment, the frame partition 11200 has at least one first clamping portion 11600, the frame base 11100 has at least one second clamping portion 11700, and the frame assembly 11300 has at least one locking portion 11800. Therefore, firstly, the top of the frame assembly 11300 can be positioned and clamped to the first clamping portion 11600 of the frame partition 11200, and the bottom of the frame assembly 11300 can be positioned and clamped to the second clamping 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 above-mentioned 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 relationship, wherein the above-mentioned motion trajectory defined by the assembly frame 10000 is also a straight line trajectory in the longitudinal direction. For example, the line between the center of the frame partition 11200 and the center of the frame base 11100 can be defined to be parallel to the above-mentioned motion trajectory. Therefore, when the moving 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 clamped and assembled with the frame assembly 11300 based on the first clamping part 11600 and the second clamping part 11700, it can be ensured that when the moving assembly 21000 moves at a high speed along the motion trajectory, the impact force applied along the direction of the motion trajectory is offset by the secure clamping connection between the first clamping part 11600 and the second clamping part 11700, or, at least based on the first clamping part 11600 and the second clamping part 11700, it is ensured that the frame assembly 11300 forms a secure assembly connection with the frame partition 11200 and the frame base 11100 in the longitudinal direction, thereby offsetting the impact force applied when the moving assembly 21000 moves at a high speed to a certain extent.

[0089] The outer shield body 12000 has a frame assembly space inside, and the outer shield body 12000 is arranged outside the frame body 11000. At least a part of at least one of the frame partition 11200, the frame assembly 11300 and the column assembly 11400 is configured to be assembled in the frame assembly space. In one embodiment, the frame assembly space at least includes a first frame unit space and a second frame unit space, and the first frame unit space and the second frame unit space are spaces separated from the above-mentioned 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] Among them, the frame partition 11200 is provided with a motion through hole, which is configured to connect the first frame unit space and the second frame unit space, the frame assembly 11300 is accommodated in the first frame unit space, and a part of the column assembly 11400 is accommodated in the second frame unit space. Therefore, when the power mechanism 20000 is assembled in the first frame unit space and relatively assembled with the frame assembly 11300, at least a part of the motion assembly 21000 of the power mechanism 20000 can enter the second frame unit space based on the motion through hole. At this time, the damper to be tested can be connected to the drive of the motion assembly 21000, so that the damper is controlled to move in the second frame unit. In this way, the power mechanism 20000 and the damper tested by the power mechanism 20000 can be located in different spaces, that is, in the first frame unit space and the second frame unit space respectively.

[0091] In one embodiment, the outer shield body 12000 includes a first unit shield body 12100 and a second unit shield body 12200, and the first unit shield body 12100 and the second unit shield body 12200 together constitute the outer shield body 12000. The first unit shield body 12100 is assembled between the frame partition 11200 and the frame base 11100, and the inner cavity of the first unit shield body 12100 is configured to form a first frame unit space between the frame partition 11200 and the frame base 11100. The second unit shield body 12200 is assembled on the frame partition 11200, and the inner cavity of the second unit shield body 12200 is configured to form a second frame unit space on the frame partition 11200, and at least a part of the second unit shield body 12200 is a perspective area. Therefore, when the damper moves in the second frame unit space, the movement of the damper can be observed using the perspective area.

[0092] In one embodiment, the frame body 11000 further includes a frame top seat 11500, which is assembled on the column assembly 11400, and the frame top seat 11500 is located on the frame partition 11200, and 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 form an integral fit, and the space between the frame partition 11200 and the frame base 11100 is used to form the second frame unit space, and the space between the frame top seat 11500 and the frame partition 11200 is used to form the second frame unit space. The frame top seat 11500, the frame partition 11200 and the frame base 11100 are assembled as a whole using the column assembly 11400, which can further enhance the structural stability of the frame body 11000.

[0093] The frame assembly 11300 can be constructed into a variety of different structural shapes according to the requirements of assembling the power mechanism 20000, the guide mechanism 30000 and the balancing mechanism 40000, for example, by combining a suitable number of plate structures. In one embodiment, the frame assembly 11300 may include a frame substrate 11310 and two frame vertical plates 11320. The frame substrate 11310 is vertically assembled on the frame base 11100, and the two frame vertical plates 11320 are vertically assembled on the frame base 11100, and the two frame vertical plates 11320 are respectively connected to the left and right sides of the frame substrate 11310. At this time, the two frame vertical plates 11320 may be perpendicular to the frame substrate 11310.

[0094] Among them, the frame substrate 11310 and the two frame uprights 11320 are configured to be used for fixing and assembling the guide mechanism 30000 of the test bench, and the guide mechanism 30000 is guided and assembled with the power mechanism 20000. Therefore, the frame substrate 11310 can be provided with a motion avoidance hole 11311, so that the motion component 21000 of the power mechanism 20000 can be located in the motion avoidance hole 11311 for movement, that is, the motion avoidance hole 11311 can be configured to allow the motion component 21000 of the power mechanism 20000 of the test bench to move therein. At this time, the motion avoidance hole 11311 can be provided with an adapted hole shape in a strip or linear shape along the direction of the motion trajectory to meet the reciprocating motion of the motion component 21000 therein. The motion avoidance hole 11311 is provided to meet the movement of the motion component 21000 and to limit the motion range of the motion component 21000 within the motion avoidance hole 11311. It also serves as a safety limitation 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-connector 11330 or a supporting angle plate 11340, and the number of the frame cross-connectors 11330 is configured to be at least two. The two sides of the two frame vertical plates 11320 are fixedly connected by at least one frame cross-connector 11330. The frame cross-connector 11330 can further reinforce the two frame vertical plates 11320, thereby improving 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 by at least one supporting angle plate 11340. At this time, the frame base 11100 and the frame partition 11200 are parallel to each other, the frame upright plate 11320 is perpendicular to the frame base 11100 and the frame partition 11200, and the angle of the supporting angle plate 11340 can also be 90°. Therefore, a plurality of supporting angle plates 11340 can be used to ensure the assembly state of the frame upright plate 11320 perpendicular to the frame base 11100 and the frame partition 11200.

[0096] The first clamping portion 11600 and the second clamping portion 11700 can be implemented in various ways such as a groove structure, a clamping ring, and a snap. For example, in one embodiment, at least one of the first clamping portion 11600 and the second clamping portion 11700 is configured to adopt a plug-in slot, and the structure of the plug-in slot can be constructed according to the end face shape formed by the combination of the frame substrate 11310 and the two frame vertical plates 11320. At this time, the first clamping portion 11600 is located on a side surface of the frame partition 11200 facing the frame base 11100, and the second clamping portion 11700 is located on a side surface of the frame base 11100 facing the frame partition 11200. Therefore, the top ends of the frame substrate 11310 and the two frame uprights 11320 are configured to be simultaneously plugged and assembled with the first clamping portion 11600, and the bottom ends of the frame substrate 11310 and the two frame uprights 11320 are configured to be simultaneously plugged and assembled with the second clamping portion 11700, and the two frame uprights 11320 are both fixedly connected to the column assembly 11400. For example, the first clamping portion 11600 and the second clamping portion 11700 may adopt an "I"-shaped groove structure that matches the combination of the frame substrate 11310 and the two frame uprights 11320.

[0097] The column assembly 11400 can be composed of a plurality of column structures. For example, in one embodiment, the column assembly 11400 includes two frame columns 11410, and the two frame columns 11410 are vertically assembled on the frame base 11100. At this time, the column assembly 11400 can also include at least two locking kits 11420, which can be fixedly mounted on the frame columns 11410 by means of snap connection, thread connection, etc. At this time, each frame column 11410 is equipped with at least one locking kit 11420, and each frame vertical plate 11320 is provided with at least one locking portion 11800. Therefore, when each frame vertical plate 11320 is matched and connected with a frame column 11410, at this time, each frame vertical plate 11320 can be fixedly connected with the locking kit 11420 of the frame column 11410 through the locking portion 11800.

[0098] Regarding the power mechanism 20000 mentioned above, the motion component 21000 of the power mechanism 20000 can adopt a variety of structures, mainly for facilitating the installation of the damper. In one embodiment, the motion component 21000 can include a motion base 21100 and an output component 21200. The motion base 21100 is movably assembled on the assembly frame 10000 along the motion trajectory. The power source drives and cooperates with the motion base 21100. At this time, the power source is used to drive the motion base 21100 to reciprocate along the motion trajectory at a preset motion speed relative to the assembly frame 10000. The output component 21200 is assembled on the motion base 21100, and the output component 21200 is configured to be connected to the damper. Therefore, when the power source drives the motion component 21000 to reciprocate along the motion trajectory at a preset motion speed relative to the assembly frame 10000, the movement 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 is convenient for connecting or installing the damper, such as a column, etc., which is not limited here.

[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 body side walls facing in different directions, and a plurality of main body side walls are arranged around the circumference of the main motion base 21110, for example, the main motion base 21110 has two main body side walls facing in opposite directions, that is, the two main body side walls are located on opposite sides of the main motion base 21110, wherein the main body top wall of the main motion base 21110 is provided with an output mounting position, and the output component 21200 is assembled at the output mounting position of the main motion base 21110. When the output component 21200 is a column, the output component 21200 can be vertically assembled at the output mounting position of the main motion base 21110, for example, the output component 21200 is directly vertically connected to the output mounting position of the main motion base 21110, or the output component 21200 can also be indirectly assembled at the output mounting position of the main motion base 21110 through a pad, a pad, etc.

[0100] The combined motion plate 21120 includes at least two motion plates 21121, and the number of the motion plates 21121 is the same as the number of the main seat side walls of the main motion seat 21110. For example, the combined motion plate 21120 has two motion plates 21121, and the two motion plates 21121 match the two main seat side walls of the main motion seat 21110. At this time, each motion plate 21121 is assembled and connected with a matching main seat side wall of the main motion seat 21110, and the plane where each motion plate 21121 is located is parallel to the motion trajectory. Among them, several moving plates 21121 are movably assembled on the assembly frame 10000 along the motion trajectory, and 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 a sliding transmission member 33000, the number of which is the same as the number of the motion plate 21121, and the sliding transmission member 33000 includes a connecting portion 4201033100 and a sliding portion 33200 connected to each other, and the connecting portion 4201033100 and the sliding portion 33200 can be set to different shapes according to requirements, such as plate-shaped, columnar, spherical, etc., which are not limited here. Each sliding transmission member 33000 is fixedly connected to a matching motion plate 21121 based on the connecting portion 4201033100 set on itself, and each sliding transmission member 33000 is movably assembled on the assembly frame 10000 based on the sliding portion 33200 set on itself. Therefore, each motion plate 21121 can be movably assembled on the assembly frame 10000 along the motion track through a matching sliding transmission member 33000.

[0102] In one embodiment, the connecting portion 4201033100 of the sliding transmission member 33000 is configured as a linear column, such as a cylinder or a prism, and at this time, the outer plate surface of the moving plate 21121 may be provided with a positioning groove 21122, and the shape and size of the positioning groove 21122 may be adapted to the connecting portion 4201033100 of the sliding transmission member 33000. For example, the positioning groove 21122 is a linear groove along the longitudinal direction of the moving plate 21121, wherein the positioning groove 21122 has a groove top wall and The two groove side walls are connected to the groove top wall. At this time, the groove 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, so that the positioning groove 21122 is open downward along the longitudinal direction, forming a groove structure with three sides enclosed and one side open, rather than a groove structure that is enclosed on all sides in the conventional situation. 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] Since the positioning groove 21122 forms a groove structure with three sides enclosed and one side open, at this time, the top of the connecting part 4201033100 can be mutually limited and abutted with the groove top wall of the positioning groove 21122. In the process that the sliding transmission member 33000 moves relative to the assembly frame 10000 based on the sliding part 33200 set on itself, when the sliding transmission member 33000 moves toward the top direction along the movement trajectory, the top of the connecting part 4201033100 can be pressed more tightly against the groove top wall of the positioning groove 21122, thereby ensuring The sliding transmission member 33000 and the moving plate 21121 maintain absolute synchronous movement when moving toward the top direction, even if the movement speed is very high, the acceleration is large, and the force between the two is also large. Based on the mutual limiting contact between the top of the connecting part 4201033100 and the top wall of the positioning groove 21122, it is also possible to ensure that the sliding transmission member 33000 and the moving plate 21121 maintain absolute synchronous movement when moving toward the top direction, thereby providing excellent testing conditions to meet the above-mentioned higher testing requirements required for the CDC damper.

[0104] In addition to the main moving seat 21110, in one embodiment, the moving base 21100 also includes an auxiliary moving seat 21130, which has at least two auxiliary seat side walls facing different directions, and a plurality of auxiliary seat side walls are arranged around the circumference of the main moving seat 21110. For example, the auxiliary moving seat 21130 has two auxiliary seat side walls facing opposite directions, that is, the two auxiliary seat side walls are located on opposite sides of the auxiliary moving seat 21130, wherein each auxiliary seat side wall of the auxiliary moving seat 21130 is parallel to a matching main seat side wall of the main moving seat 21110 and is in the same plane.

[0105] The inner side surface of each moving plate 21121 is provided with a first clamping portion 21123 and a second clamping portion 21124, each main seat side wall of the main moving seat 21110 is clamped and assembled with the first clamping portion 21123 of a matching moving plate 21121, and each auxiliary seat side wall of the auxiliary moving seat 21130 is clamped and assembled with the second clamping portion 21124 of a matching moving plate 21121. For example, the inner side surfaces of the two moving plates 21121 are provided with a first clamping portion 21123 and a second clamping portion 21124, the two main seat side walls of the main moving seat 21110 are clamped and assembled with the first clamping portions 21123 of the two moving plates 21121, and the two auxiliary seat side walls of the auxiliary moving seat 21130 are clamped and assembled with the second clamping portions 21124 of the two moving plates 21121.

[0106] In one embodiment, the first clamping portion 21123 is configured as a first clamping groove, the first clamping groove having a groove top wall and a groove bottom wall opposite to each other along the longitudinal direction of the moving plate 21121, and the first clamping groove having two through grooves opposite to each other along the transverse direction of the moving plate 21121, the main moving seat 21110 is clamped and assembled in the first clamping groove, and the top of the main moving seat 21110 is in limiting contact with the groove top wall of the first clamping groove, and the bottom of the main moving seat 21110 is in limiting contact with the groove bottom wall of the first clamping groove.

[0107] The second clamping portion 21124 is configured as a second clamping groove, the second clamping groove has a groove top wall and a groove bottom wall which are opposite to each other along the longitudinal direction of the moving plate 21121, and the second clamping groove has two through grooves which are opposite to each other along the transverse direction of the moving plate 21121, the auxiliary moving seat 21130 is clamped and assembled in the second clamping groove, and the top of the auxiliary moving seat 21130 is in limiting contact with the groove top wall of the second clamping groove, and the bottom of the auxiliary moving seat 21130 is in limiting contact with the groove bottom wall of the second clamping groove.

[0108] Therefore, in the process of several moving plates 21121 moving relative to the assembly frame 10000 based on the sliding transmission member 33000, when several moving plates 21121 move toward the top direction along the movement trajectory, the top of the main moving seat 21110 and the top wall of the first clamping groove will be squeezed against each other more tightly, thereby ensuring that the main moving seat 21110 and the moving plate 21121 maintain absolute synchronous movement when moving toward the top direction, even if the movement speed is very high, the acceleration is very large, and the force between the two is also very large, based on the mutual limiting contact between the top of the main moving seat 21110 and the top wall of the first clamping groove, it is also possible to ensure that the main moving seat 21110 and the moving plate 21121 maintain absolute synchronous movement when moving toward the top direction, thereby providing excellent testing conditions to meet the above-mentioned higher testing requirements required for the CDC damper.

[0109] Similarly, when several moving plates 21121 move toward the top along the motion trajectory, the top of the auxiliary moving seat 21130 and the top wall of the second clip groove will be squeezed against each other more tightly, thereby ensuring that the auxiliary moving seat 21130 and the moving plate 21121 maintain absolute synchronous movement when moving toward the top. Even if the movement speed is very high, the acceleration is very large, and the force between the two is also very large, based on the mutual limiting contact between the top of the auxiliary moving seat 21130 and the top wall of the second clip groove, it is also possible to ensure that the auxiliary moving seat 21130 and the moving plate 21121 maintain absolute synchronous movement when moving toward the top.

[0110] Similarly, when several moving plates 21121 move toward the bottom along the motion trajectory, the bottom of the main moving seat 21110 and the bottom wall of the first clamping groove will be squeezed against each other more tightly, thereby ensuring that the main moving seat 21110 and the moving plate 21121 maintain absolute synchronous movement when moving toward the bottom. Even if the movement speed is very high, the acceleration is very large, and the force between the two is also very large, based on the mutual limiting contact between the bottom of the main moving seat 21110 and the bottom wall of the first clamping groove, it is also possible to ensure that the main moving seat 21110 and the moving plate 21121 maintain absolute synchronous movement when moving toward the bottom.

[0111] At the same time, when several moving plates 21121 move toward the bottom along the motion trajectory, the bottom of the auxiliary moving seat 21130 and the bottom wall of the second clip groove will be squeezed against each other more tightly, thereby ensuring that the auxiliary moving seat 21130 and the moving plate 21121 maintain absolute synchronous movement when moving toward the bottom. Even if the movement speed is very high, the acceleration is very large, and the force between the two is also very large, based on the mutual limiting contact between the bottom of the auxiliary moving seat 21130 and the bottom wall of the second clip groove, it can also ensure that the auxiliary moving seat 21130 and the moving plate 21121 maintain absolute synchronous movement when moving toward the bottom.

[0112] In one embodiment, the moving plate 21121 may include an intermediate plate 21125, a top plate 21126 and a bottom plate 21127, wherein the intermediate plate 21125, the top plate 21126 and the bottom plate 21127 are three parts of the moving plate 21121, and thus the intermediate plate 21125, the top plate 21126 and the bottom plate 21127 may be integrally formed to constitute the moving plate 21121. The top plate 21126 is connected to the top of the intermediate plate 21125, and the first clamping portion 21123 is disposed on the top plate 21126, and the top plate 21126 is configured to be connected to the side wall of the main body seat of the main moving seat 21110 through the first clamping portion 21123. The bottom plate 21127 is connected to the bottom of the middle plate 21125 , and the second clamping portion 21124 is disposed 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 clamping portion 21124 .

[0113] In one embodiment, the guide mechanism 30000 includes at least one guide column member 31000. For example, two guide column members 31000 that cooperate with each other in parallel are arranged at the same time. The guide column member 31000 is a linear column. The guide column member 31000 is configured to form a guide track. Therefore, the main moving seat 21110 and the auxiliary moving seat 21130 can be provided with a guide hole 21140, and all the guide column members 31000 are movably inserted into the guide hole 21140.

[0114] Among them, each guide hole 21140 can be equipped with a floating sleeve, and the guide column part 31000 is movably inserted into the floating sleeve in the guide hole 21140. Based on the indirect assembly of the floating sleeve between the guide column part 31000 and the guide hole 21140, the friction force of the guide column part 31000 can be greatly reduced when the guide column part 31000 reciprocates relative to the guide hole 21140. Therefore, when the main moving seat 21110 and the auxiliary moving seat 21130 reciprocate along the motion trajectory, the movement speed can be increased due to the greatly reduced friction force. The guide column part 31000 can ensure that the main moving seat 21110 and the auxiliary moving seat 21130 accurately reciprocate along the motion trajectory and the guide trajectory based on the formed guide trajectory, thereby providing stable and precise testing conditions.

[0115] Regarding the guide mechanism 30000 mentioned above, in one embodiment, the guide mechanism 30000 may include a guide base 32000 and a sliding transmission member 33000. The guide 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 slot 32110, and the slots of the guide slots 32110 of the unit bases 32100 are arranged in opposite directions, wherein the guide slots 32110 of the unit bases 32100 are configured to form a guide track together, the guide track is a straight track, and the guide track is configured to guide the power mechanism 20000 of the test bench to reciprocate, that is, to guide the motion component 21000 in the power mechanism 20000 to reciprocate along the guide track and the motion track.

[0116] The 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 set to different shapes according to needs, such as plate-shaped, columnar, spherical, etc., which are not limited here. Among them, 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, and the sliding portion 33200 of each sliding transmission member 33000 is slidably assembled with a matching guide groove 32110 of the guide base 32000, so that the sliding transmission member 33000 reciprocates along the guide track relative to the guide base 32000; the connecting portions 4201033100 of several sliding transmission members 33000 are configured to be used for jointly connecting the power mechanism 20000 of the test bench, that is, the moving component 21000 is connected to the connecting portion 4201033100 of the guide mechanism 30000, thereby being movably assembled relative to the guide mechanism 30000 along the guide track.

[0117] Therefore, the sliding transmission member 33000 reciprocates along the guide track relative to the guide base 32000, which can form a guide aid to ensure that the motion component 21000 accurately reciprocates along the motion track during high-speed motion, and prevent the motion component 21000 from deviating when the motion speed is too high. When the motion component 21000 increases the motion speed, the damper is effectively tested for working conditions. Under the background of the rapid development of CDC dampers, the CDC damper's damping is continuously adjustable and has a fast adjustment speed, providing stable test conditions to meet the higher test requirements required by the CDC damper.

[0118] The reciprocating motion of the sliding transmission member 33000 relative to the guide base 32000 can be achieved in a variety of ways. For example, in one embodiment, the sliding portion 33200 includes a connected sliding section 33210 and a limiting section 33220, and the sliding section 33210 and the limiting section 33220 are two sections of the entire sliding portion 33200. The sliding section 33210 and the limiting section 33220 together constitute the sliding portion 33200, wherein the sliding section 33210 and the limiting section 33220 can be designed as an integral molding, but different sections are separated from the sliding portion 33200 according to specific needs as the sliding section 33210 and the limiting section 33220. At this time, the connecting part 4201033100 is connected to the sliding section 33210 of the sliding part 33200, and the limiting section 33220 of the sliding part 33200 is indirectly connected to the connecting part 4201033100 through the sliding section 33210, and the distance between the sliding section 33210 and the connecting part 4201033100 is smaller than the distance between the limiting section 33220 and the connecting part 4201033100.

[0119] In coordination, the guide slot 32110 includes a sliding slot section 32111 and a limiting slot section 32112 which are connected to each other. The sliding slot section 32111 and the limiting slot section 32112 are two spatial parts in the entire guide slot 32110, and the sliding slot section 32111 and the limiting slot section 32112 together constitute the guide slot 32110. At this time, the sliding section 33210 of the sliding part 33200 is slidably assembled in the sliding slot section 32111 of the guide slot 32110 along the guide track, and the limiting slot section 33220 of the sliding part 33200 is slidably assembled in the limiting slot section 32112 of the guide slot 32110 along the guide track, and the limiting slot section 32112 is configured to prohibit the limiting segment 33220 from moving in other directions deviating from the guide track.

[0120] The prohibition effect mentioned above can prevent the limiting section 33220 from laterally disengaging from the limiting groove section 32112, thereby ensuring that the entire sliding portion 33200 is only slidably assembled in the guide groove 32110 along the guide track, and during the sliding process, regardless of whether the sliding portion 33200 is subjected to a force that deviates from the guide track, it will not deviate from the guide track for movement. Therefore, during the high-speed movement, the stability of the assembly between the sliding portion 33200 and the guide groove 32110 is maintained. Even if the moving component 21000 is in a high-speed movement process, it can provide stable and precise guidance for the high-speed movement of the moving component 21000, ensuring that the moving component 21000 only moves at high speed along the moving trajectory and the guide trajectory.

[0121] Regarding the implementation of the above-mentioned prohibition effect, in one embodiment, the width of the slot body of the sliding slot section 32111 can be limited to be smaller than the width of the slot body of the limiting slot section 32112, and the width of the sliding section 33210 can be smaller than the width of the limiting segment 33220. Moreover, the width of the limiting segment 33220 is larger than the width of the slot body of the sliding slot section 32111, so that the limiting segment 33220 can only be slidably assembled in the limiting slot section 32112 along the guide track, and cannot deviate from the guide track to slide, thereby, through the design of matching the size of the limiting segment 33220 and the sliding slot section 32111, the limiting segment 33220 is prohibited from detaching from the limiting slot section 32112, and further prohibited from moving in other directions deviating from the guide track.

[0122] In one embodiment, the sliding portion 33200 of the sliding transmission member 33000 is configured as a plate-shaped component, and the guide slot 32110 is a plate-shaped slot. Moreover, a sliding guide plate 32120 is arranged inside the guide slot 32110. The sliding guide plate 32120 can be a variety of disc shapes such as round and square. The number of the sliding guide plates 32120 is configured as two. In this case, the guide slot 32110 has two inner side walls facing oppositely. The two sliding guide plates 32120 are symmetrically arranged on two opposite inner side walls of the guide slot 32110, and the space between the two sliding guide plates 32120 constitutes a sliding slot section 32111. Among them, since the two sliding guide plates 32120 are assembled in the guide slot 32110, they will occupy part of the space in the guide slot 32110. However, there is another part of the space in the guide slot 32110 that is not occupied by the two sliding guide plates 32120. At this time, the other part of the space in the guide slot 32110 that is not occupied by the two sliding guide plates 32120 can be used to form the limiting slot section 32112. Therefore, by assembling the sliding guide plates 32120 in the guide slot 32110, the sliding slot section 32111 and the limiting slot section 32112 are distinguished in the guide slot 32110, wherein the limiting slot section 32112 is located on the inner side of the sliding slot section 32111 in the guide slot 32110.

[0123] Regarding the implementation method of the sliding section 33210 of the above-mentioned sliding part 33200 slidingly assembled in the sliding groove section 32111 of the guide groove 32110 along the guide track, in one embodiment, the sliding guide plate 32120 includes an inner plate surface and an outer plate surface facing oppositely, the inner plates of the two sliding guide plates 32120 face oppositely, and the outer plates of the two sliding guide plates 32120 are fixedly connected to the two opposite inner walls of the guide groove 32110, for example, by a snap connection, a threaded connection, etc.

[0124] At this time, the two opposite inner side walls of the guide slot 32110 are both provided with positioning unit parts 32130, and the outer disk surface of the sliding guide plate 32120 is provided with a docking unit part 32140 for positioning and matching with the positioning unit part 32130. The positioning unit part 32130 and the docking unit part 32140 can be matched with each other in a variety of structures, so that the sliding guide plate 32120 is positioned and assembled with the positioning unit part 32130 in the guide slot 32110 through the docking unit part 32140. For example, in one embodiment, the positioning unit part 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 part 32130 includes a first guide protrusion 32131 and a second guide protrusion 32132, and the first guide protrusion 32131 and the second guide protrusion 32132 are both configured as straight protrusions parallel to the guide track, and the sliding guide plate 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 plate 32120 between the first guide protrusion 32131 and the second guide protrusion 32132, so that the two sides of the sliding guide plate 32120 are respectively in limited contact with the first guide protrusion 32131 and the first guide protrusion 32131, and it is prohibited to move 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 above-mentioned two sides of the sliding guide plate 32120 are the outer end and the inner end of the sliding section 33210. When the sliding guide plate 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 have a limiting contact with the outer end and the inner end of the sliding guide plate 32120, and also have the effect of limiting the sliding section 33210 from being able to laterally separate from between 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 plate 32120 and the guide groove 32110 is maintained. Even if the moving component 21000 is in the high-speed movement process, it can provide stable and precise guidance for the high-speed movement of the moving component 21000, ensuring that the moving component 21000 only moves at high speed along the movement trajectory and the guide trajectory.

[0127] In addition, in order to enhance the above-mentioned limiting effect, in one embodiment, the positioning unit portion 32130 may further include a third guide protrusion 32133, the third guide protrusion 32133 is located between the first guide protrusion 32131 and the second guide protrusion 32132, the docking unit portion 32140 includes a docking guide groove 32141, and the sliding guide plate 32120 is slidably assembled with the third guide protrusion 32133 through the docking guide groove 32141. The extension direction of the third guide protrusion 32133 is parallel to the guide track, and the protrusion width of the third guide protrusion 32133 is greater than the protrusion 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 if the moving component 21000 is in high-speed motion, it can provide stable and precise guidance for the high-speed motion of the moving component 21000, ensuring that the moving component 21000 only moves at high speed along the motion trajectory and the guide trajectory.

[0128] Regarding the above-mentioned 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, and all balancing bases 41000 are distributed along a preset annular distribution track. The top of the base body of each balancing base 41000 has an assembly top surface, and the assembly top surfaces of all balancing bases 41000 are in the same plane. Therefore, the several balancing bases 41000 can cooperate with each other, and each of the balancing bases 41000 can provide a balancing base point in the overall balancing mechanism 40000. The balancing base points formed by the several balancing bases 41000 at different positions in the annular distribution track finally form an annular balancing combination structure formed along the annular distribution track.

[0129] It should be noted that the annular balancing combination structure is not a continuous ring, but an intermittent annular balancing combination structure formed in the annular distribution trajectory based on the setting quantity and distribution density of the balancing bases 41000. The purpose is to be able to adjust the number, distribution density, distribution method, etc. of a number of balancing bases 41000 according to actual support requirements, to form a targeted and stable balancing support force, to ensure that the moving component 21000 provides stable balancing support for the moving component 21000 during high-speed movement, to prevent the moving component 21000 from being assembled unstable relative to the assembly frame 10000 when the movement speed of the moving component 21000 is too high, thereby causing movement deviation.

[0130] The number of the balancing frames 42000 is configured as a plurality of balancing frames 42000, and the function of the balancing frames 42000 is to connect the plurality of balancing bases 41000, so that each independent balancing base 41000 can be connected to form one or more relatively stable integral structures through the balancing frames 42000. 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 parts 4201033100 and at least one recessed part 4201033100. The recessed portion 42020 is a groove structure, and the recessed portion 42020 can be used to avoid the movement of the motion component 21000, that is, the motion component 21000 can enter and exit the recessed portion 42020 during the high-speed reciprocating motion. The connecting portion 4201033100 of the balancing frame 42000 is configured to be connected to the assembly top surface of the balancing base 41000, and each recessed portion 42020 of the balancing frame 42000 is located between two adjacent balancing bases 41000. Therefore, part of the structure of the motion component 21000 can be located between adjacent balancing bases 41000 for movement, thereby forming a balanced support on different sides of the motion component 21000 through the adjacent balancing bases 41000 to ensure the balancing effect during the movement.

[0131] In one embodiment, the balancing mechanism 40000 may include a balancing pad 43000 or a supporting element 44000. The number of balancing pads 43000 is configured to be several, and each balancing pad 43000 is configured to be assembled in a matching recessed portion 42020 of the balancing frame 42000. The side of the balancing pad 43000 is in force-supported contact with the inner side wall of the recessed portion 42020, thereby force-supporting the overall frame structure of the balancing frame 42000, preventing the balancing frame 42000 from being deformed due to the large impact force applied to the balancing frame 42000 by the moving component 21000 during high-speed movement, and preventing the balancing frame 42000 from reducing the stability of the balancing support due to deformation. The number of the supporting elements 44000 is configured to be several, and one supporting element 44000 is provided on the assembly top surface of each balancing base 41000, and each connecting portion 4201033100 of the balancing frame 42000 is connected to the assembly top surface of the balancing base 41000 through the supporting element 44000. The supporting element 44000 can be assembled by bolts, nuts and other parts, in order to stably connect the balancing frame 42000 and the balancing base 41000.

[0132] The number and matching method 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 the balancing bases 41000 is an even number, and the number of the balancing bases 41000 is configured as at least two pairs, each pair of balancing bases 41000 is matched and connected with a balancing frame 42000, wherein each balancing frame 42000 has two connecting parts 4201033100 respectively located at both ends and a recessed part 42020 located between the two connecting parts 4201033100, and the two connecting parts 4201033100 of each balancing frame 42000 are connected to the two assembly top surfaces of each pair of balancing bases 41000.

[0133] Among them, the annular distribution trajectory can be configured as a square annular trajectory, and the square trajectory is equivalent to a circular trajectory formed along the edge of the square. Therefore, the square annular trajectory has four vertices, and the number of balancing bases 41000 is configured to be four. The four balancing bases 41000 are respectively arranged at the four vertices of the square annular trajectory, and the number of balancing frames 42000 is configured to be two. The two connecting parts 4201033100 of each balancing frame 42000 are connected to the two assembly top surfaces of the same pair of balancing bases 41000.

[0134] In one embodiment, the balancing frame 42000 includes a connecting plate 42100 and a curved plate 42200. At least a portion of the plate area of ​​the connecting plate 42100 is configured to form a connecting portion 4201033100, wherein the number of connecting plates 42100 is configured to be two. At this time, at least a portion of the plate area of ​​the curved plate 42200 has a concave curved surface, and the curved surface of the curved plate 42200 is configured to form a concave portion 42020, and the two ends of the curved plate 42200 are respectively connected to the two connecting plates 42100. Therefore, a complete balancing frame 42000 can be formed by one curved plate 42200 and two connecting plates 42100.

[0135] The curved panel 42200 may be configured as a U-shaped structure or the like, thereby forming a recessed portion 42020 in the middle of the curved panel 42200. In one embodiment, the curved panel 42200 may include a bottom panel 42210 and two vertical panels 42220, wherein both ends of the bottom panel 42210 are respectively connected to one end of the two vertical panels 42220, and each vertical panel 42220 is connected to the bottom panel 42210 at an angle, and the angle of ... ° to 120°, for example, an angle of 90° or about 90°, thereby forming a recessed portion 42020 through the inclined connection of the bottom plate 42210 and the two vertical plate members 42220, the other ends of the two vertical plate members 42220 are respectively connected to the two connecting plates 42100, and each vertical plate member 42220 is connected to the connecting plate 42100 at an inclined angle, and the angle of the inclined connection can be set between 60° and 120°, for example, an angle of 90° or about 90°.

[0136] The connecting plate 42100 and the curved plate 42200 are configured as an integral structure, or the bottom plate 42210 and the two vertical plates 42220 can also be configured as an integral structure, so that each balancing frame 42000 can be configured as an integral structure. A reinforcing angle plate 42230 can also be provided between the curved plate 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 stable bottom plate 41400. The stable bottom plate 41400 can be used as an assembly basis 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. 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. 00, the stable base plate 41400 is configured as an assembly frame 10000 for assembly on a test bench, wherein the cross-sectional area of ​​the stable base plate 41400 is larger than the cross-sectional area of ​​the balancing base 41300, and the balancing base 41300 is assembled on the stable base plate 41400. Based on the larger cross-sectional area, the stable base plate 41400 provides a more stable assembly foundation for the balancing column 41100, the balancing top seat 41200, and the balancing base 41300, so that the entire balancing base 41000 has a stable overall structure.

[0138] In addition, in one embodiment, the balancing base 41000 may further include a balancing pole 41500, the number of which is configured as a plurality, the plurality of balancing poles 41500 are parallel to the balancing column 41100, and the balancing poles 41500 are arranged around the balancing column 41100 along the circumference of the balancing column 41100, the top end of each balancing pole 41500 is plugged and assembled with the balancing top seat 41200, and the bottom end of each balancing pole 41500 is plugged and assembled with the balancing base 41300. The ratio of the diameter of the balancing column 41100 to the diameter of the balancing pole 41500 is between 5 and 15, that is, the balancing pole 41500 is thinner than the balancing column 41100.

[0139] Since several balancing poles 41500 are arranged in the circumferential direction of the balancing column 41100, the assembly of the balancing top seat 41200 and the balancing base 41300 can be further reinforced in the circumferential direction of the balancing column 41100. During the high-speed movement of the moving component 21000, the moving component 21000 may exert a large impact force on the balancing frame 42000 and different balancing bases 41000. In order to avoid the balancing column 41100, the balancing base 41000 and the balancing pole 41500 may be assembled together. The balance top seat 41200, the balance base 41300 and the stable bottom plate 41400 are in a stable assembly state even under a large impact force, and a number of circumferentially distributed balance rods 41500 can form force supports for the balance top seat 41200 and the balance base 41300 at different circumferential positions of the balance column 41100, ensuring that all components of the balance base 41000 are in a stable assembly state, thereby ensuring that high-demand test conditions can be provided for the damper through the high-speed movement of the moving component 21000.
