[0050] See Figures 1 to 7 As shown, this application provides a test bench for damper experimental testing. The test bench includes an assembly frame 10000, a power mechanism 20000, a guide mechanism 30000, and a balancing mechanism 40000. The assembly frame 10000 serves as the assembly base for the power mechanism 20000, guide mechanism 30000, and balancing mechanism 40000. The specific dimensions and structure of the assembly frame 10000 can be specifically designed based on the assembly requirements of the power mechanism 20000, guide mechanism 30000, and balancing mechanism 40000. The assembly frame 10000 is configured to define a linear motion trajectory, which limits the movement of the power mechanism 20000.

[0051] The assembly frame 10000 includes a frame body 11000 and an outer protective cover 12000. 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 inner cavity of the first unit cover 12100 is configured to form a first frame unit space. The inner cavity of the second unit cover 12200 is configured to form a second frame unit space, and 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.

[0052] The power mechanism 20000 includes a power source and a motion component. The power source is mounted on the assembly frame 10000, and the motion component is mounted on the assembly frame 10000 along a motion trajectory. The power source and the motion component drive each other. The power source can adopt different types of power such as electromagnetic power and mechanical power. The power source provides the energy source for the motion of the motion component. Thus, the power source can drive the motion component to reciprocate relative to the assembly frame 10000 along the motion trajectory at a preset motion speed. This motion speed can be adjusted according to actual needs. Thus, when the motion component is connected to the damper, the motion of the motion component can synchronously drive the damper to move at the same speed. This method is used to control the damper to simulate operation and test the working condition of the damper.

[0053] During the operational testing of the damper by the aforementioned motion component, the guide mechanism 30000 further provides guiding assistance to the motion component, and the balancing mechanism 40000 further provides balancing assistance to the motion component. Specifically, the guide mechanism 30000 is mounted on the assembly frame 10000 and is configured to form a guide trajectory. The guide trajectory is a straight line and parallel to the motion trajectory. The motion component is movably assembled relative to the guide mechanism 30000 along the guide trajectory. The balancing mechanism 40000 is mounted on the assembly frame 10000, and at least one of the guide mechanism 30000 and the power mechanism 20000 is mounted on the balancing mechanism 40000.

[0054] The guiding aid is mainly used to ensure that the moving components move accurately along the motion trajectory during high-speed movement, and to prevent the movement of the moving components from deviating when the movement speed is too high. The balancing mechanism 40000 is mainly used to ensure that the moving components maintain stability during high-speed movement, and to prevent the moving components from becoming unstable relative to the assembly frame 10000 when the movement speed is too high, which would lead to deviation of the movement.

[0055] Therefore, it can be seen that the guiding and balancing assistance provided by the guiding mechanism 30000 and the balancing mechanism 40000 to the power mechanism 20000 can ensure that the motion components of the power mechanism 20000 maintain high precision and high stability during the motion test of the damper. When the motion component increases its speed, it can also effectively test the working condition of the damper. In the context of the rapid development of CDC dampers, it provides stable test conditions for the characteristics of CDC dampers that the damping is continuously adjustable and the adjustment speed is fast, thus meeting the higher test requirements of CDC dampers.

[0056] 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 in the power mechanism 20000 to reciprocate along the guiding trajectory and the motion trajectory.

[0057] The sliding transmission member 33000 includes a connecting portion 33100 and a sliding portion 33200 that are interconnected. The connecting portion 33100 and the sliding portion 33200 can be configured with 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 portion 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 portions 33100 of several sliding transmission members 33000 are configured to jointly connect to the power mechanism 20000 of the test bench, that is, the motion component is connected to the connecting portion 33100 of the guide mechanism 30000, thereby being movably assembled relative to the guide mechanism 30000 along the guide trajectory.

[0058] 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 moving component accurately reciprocates along the motion trajectory during high-speed movement, preventing deviation from the motion when the moving component's speed is too high. When the moving component 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.

[0059] 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 33100 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 33100 through the sliding segment 33210, and the distance between the sliding segment 33210 and the connecting part 33100 is less than the distance between the limiting segment 33220 and the connecting part 33100.

[0060] 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.

[0061] 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 is in high-speed movement, it can provide stable and precise guidance for the high-speed movement of the moving component, ensuring that the moving component moves at high speed only along the movement trajectory and the guide trajectory.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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 preventing 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 moving component is in the process of high-speed movement, it can provide stable and accurate guidance for the high-speed movement of the moving component, ensuring that the moving component only moves at high speed along the movement trajectory and the guide trajectory.

[0068] 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 moving component is in high-speed motion, it can provide stable and precise guidance for the high-speed motion of the moving component, ensuring that the moving component moves at high speed only along the motion trajectory and the guide trajectory.

[0069] This application provides a testing system, which includes a test bench, a driver, a controller, and a host computer. The driver is connected to the test bench, the controller is connected to at least one of the test bench and the driver, and the host computer is connected to at least one of the test bench, the driver, and the controller. Since the specific structure, functional principle, and technical effects of the aforementioned guide mechanism 30000 and the test bench have been described in detail above, they will not be repeated here. Any technical details regarding the aforementioned guide mechanism 30000 and the test bench can be found in the foregoing description.

[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
