Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0044] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone.

[0049] like Figures 1 to 7As shown, this embodiment provides a shock-absorbing mechanism for supporting a vibrating body to reduce the damage caused by its vibration to the drive shaft connected to the vibrating body. The shock-absorbing mechanism includes a base 100, a lifting member 200, a height adjusting member 300, and a buffer member 400. The lifting member 200 is movably disposed on the base 100 along a first direction to move closer to or further away from the base 100. The lifting member 200 has a first adjusting part 210. The height adjusting member 300 has a second adjusting part 310. The height adjusting member 300 is movably disposed on the base 100, rotating about the first direction or along a second direction at an angle to the first direction. At least one of the first adjusting part 210 and the second adjusting part 310 is an inclined surface. The first adjusting part 210 and the second adjusting part 310 cooperate with each other. The height adjusting member 300 moves to drive the cooperation position of the second adjusting part 310 and the first adjusting part 210 to move on the inclined surface, thereby driving the lifting member 200 to move away from / closer to the base 100. The buffer member 400 has a bearing part 410 for bearing the vibrating body. The buffer member 400 is mounted on the lifting member 200.

[0050] The shock absorption mechanism 10 adjusts the movement of the lifting member 200 through the height adjustment member 300, thereby driving the buffer member 400 on the lifting member 200 to move, so as to adapt to the vibrating body at different heights. Under the action of the buffer member 400, the vibration generated by the vibrating body during operation can be effectively reduced. During use, the risk of fatigue fracture of the transmission shaft connected to the vibrating body is reduced.

[0051] It should be noted that the vibrating body in this embodiment is the stator of the motor 800, and the rotor of the motor 800 is connected to the transmission shaft, which is a cantilever structure.

[0052] In some embodiments, the bottom of the lifting member 200 has a first inclined surface to form a first adjusting portion 210, the first inclined surface being inclined upward or downward along a first direction; the top of the height adjusting member 300 has a second inclined surface parallel to the first inclined surface to form a second adjusting portion 310, and the height adjusting member 300 is movably disposed on the base 100 along a second direction. (Reference) Figure 1 As shown, the first direction is the vertical direction; the second direction is the front-back direction. Preferably, the first inclined plane is inclined forward and upward. This structure allows the height adjusting member 300 to move along the second direction, which in turn pushes the lifting member 200 upward through the interaction of the two inclined planes. This process is stepless, enabling high-precision adjustment of the height of the lifting member 200. In other embodiments, the height adjusting member 300 can be a screw 510; the height adjusting member 300 rotates along the first direction and drives the lifting member 200 to move.

[0053] Regarding the position adjustment of the height adjusting member 300, in some embodiments, the height adjusting member 300 has a threaded hole 320 with its axis extending along a second direction; the damping mechanism 10 also includes a bolt 500, which is threadedly engaged with the threaded hole 320 and engages with the axial limiting portion of the base 100 to constrain the bolt 500 to be fixed to the base 100 in its own axial direction. This structure allows the height adjusting member 300 to move along the second direction during the rotation of the bolt 500 relative to the base 100. Specifically, when the bolt 500 rotates clockwise, the height adjusting member 300 moves backward, thereby causing the lifting member 200 to rise; when the bolt 500 rotates counterclockwise, the height adjusting member 300 moves forward, and the lifting member 200 descends under its own gravity.

[0054] Combination Figure 2 As shown, the axial limiting part includes an adjusting hole 110 located on the base 100 and coaxially arranged with the threaded hole 320; the bolt 500 includes a screw 510 and a screw head 520 located at the end of the screw 510. The outer diameter of the screw head 520 is larger than the outer diameter of the adjusting hole 110. The screw 510 passes through the adjusting hole 110 and is threaded into the threaded hole 320. The second inclined surface slopes downward in the direction toward the screw head 520. When the bolt 500 rotates clockwise, the distance between the screw head 520 and the height adjusting member 300 shortens. Due to the abutment between the screw head 520 and the base 100, relative displacement of the screw head 520 relative to the base 100 is avoided, thereby causing the height adjusting member 300 to move backward. When the bolt 500 rotates counterclockwise, the distance between the screw head 520 and the height adjusting member 300 increases, and the lifting member 200 descends, thereby driving the height adjusting member 300 to move forward, thus keeping the screw head 520 in abutment with the base 100.

[0055] To ensure the stability of the lifting component 200 under stress, in some embodiments, there are two first inclined surfaces along a third direction, and two second inclined surfaces are respectively disposed on both sides of the threaded hole 320. There are two second inclined surfaces, which slide in cooperation with the two first inclined surfaces one to one. In this embodiment, the third direction is the left-right direction.

[0056] In some embodiments, combined with Figure 4 and Figure 5As shown, the height adjustment component 300 has a sliding groove 330 extending along the second direction, the base 100 has a mounting hole, and the shock absorption mechanism 10 also includes a first guide component 610. One end of the first guide component 610 is installed in the mounting hole, and the other end is located in the sliding groove 330, and it is used to constrain the sliding path of the height adjustment component 300. The cooperation between the sliding groove 330 and the first guide component 610 can restrict the rotation of the height adjustment component 300 around the axis of the bolt 500, and it is easy to process and has low cost. In this embodiment, the first guide component 610 can be a guide rod, the lower section of which is threaded and screwed into the mounting hole. Further, the guide rod is a cylindrical structure. The axial direction of the adjustment hole 110 is parallel to the extension direction of the sliding groove 330, so the cooperation between the bolt 500 and the adjustment hole 110 can also play a certain constraining role on the movement trajectory of the height adjustment component 300. The height adjustment component 300 is constrained at two points, thus enabling it to move more smoothly along the second direction.

[0057] To ensure the trajectory of the lifting member 200 during lifting and lowering, in some embodiments, the shock-absorbing mechanism 10 further includes a second guide member 620. The base 100 is provided with a guide channel 120 extending along a first direction. The second guide member 620 is connected to the lifting member 200 and slidably disposed in the guide channel 120. The second guide member 620 has a rod-like structure, with its upper section threaded and screwed into a threaded hole in the lifting member 200, and its lower section located in the guide channel 120. To ensure force balance, there are at least two second guide members 620, and at least two guide channels 120, each corresponding to one of the second guide members 620.

[0058] Considering that the stator of the motor 800 has a cylindrical structure, in some embodiments, the bearing portion 410 of the buffer 400 is an arc-shaped surface to adapt to the peripheral sidewall of the stator of the motor 800 that needs to be supported, so as to increase the contact area between the buffer 400 and the stator, avoid the buffer 400 being locally crushed, and improve the bearing capacity of the buffer 400.

[0059] The buffer 400 also includes a mounting portion 420, which is located on one side of the support portion 410 and is screwed to the lifting member 200. A screw passes through a fixing hole extending along the first direction through the mounting portion 420 and is screwed to the lifting member 200, thereby reducing the possibility of the screw connecting the mounting portion 420 and the lifting member 200 colliding with the motor 800. There are two mounting portions 420, located on opposite sides of the support portion 410. The top of each mounting portion 420 is planar and perpendicular to the first direction.

[0060] In some embodiments, the buffer 400 is made of an elastic material such as polyethylene, polypropylene, polyvinyl chloride, thermoplastic elastomer, polyurethane, or ethylene-vinyl acetate copolymer.

[0061] CombinationFigure 1 As shown, to facilitate the connection between the base 100 and the external structure, the shock absorption mechanism 10 also includes a connector 130. The connector 130 is L-shaped and includes a vertical plate and a horizontal plate connected together. The vertical plate is screwed to the base 100, and the horizontal plate is screwed to the external structure. There are two connectors 130, which are located on both sides of the base 100 along a third direction.

[0062] This embodiment also provides an aging device, which includes a frame 700, a motor 800, a fan assembly 900, and a vibration damping mechanism 10 as described in any of the above embodiments. The frame 700 has an aging chamber inside. The base 100 of the fan assembly 900 and the vibration damping mechanism 10 is disposed on the frame 700. The motor 800 is mounted on the bearing portion 410 through its own peripheral sidewall, and the output end of the motor 800 is connected to the fan assembly 900. Through the action of the buffer 400 in the vibration damping mechanism 10, the vibration generated by the motor 800 during operation can be effectively reduced, thereby reducing the risk of fatigue fracture of the drive shaft connected to the rotor of the motor 800 during use.

[0063] The frame 700 has a support bracket 720 inside, and several support plates 730 are arranged at intervals along a first direction inside the support bracket 720. The support plates 730 are used to support the test piece. The frame 700 is surrounded by an air duct plate 710, which is located on the top and sides of the support bracket 720. The air duct plate 710 and the support bracket 720 form a circulating air duct, and the airflow generated by the fan assembly 900 flows in the circulating air duct. Specifically, in conjunction with Figure 6 As shown, the airflow enters the support bracket 720 from the right side and exits from the left side of the support bracket 720. It then flows over the top of the support bracket 720, passes through the fan assembly 900, flows to the right, enters the right side of the support bracket 720 again, and flows into the interior of the support bracket 720 from the right side.

[0064] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
