[0002] Products inevitably encounter various environmental conditions during manufacturing, assembly, and transportation. For example, automotive parts can be damaged by vibration during transport.

[0065] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. To make the technical solutions and advantages of this application clearer, the vibration device, etc., will be described in detail below with reference to the accompanying drawings.

[0066] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this application embodiment provides a vibration device, which includes a transmission assembly 1, a drive assembly 2, and a stage 3. The transmission assembly 1 includes a rotating shaft 11 and an eccentric column 12. The rotating shaft 11 is connected to the drive assembly 2 and rotates under the drive of the drive assembly 2. The eccentric column 12 extends parallel to the axial direction of the rotating shaft 11 and is connected to the rotating shaft 11. The axis of the eccentric column 12 is parallel to and does not coincide with the axis of the rotating shaft 11. The stage 3 has a first seat 31 and a limiting stage 32. The first seat 31 and the limiting stage 32 are connected to the side of the transmission assembly 1. A first bearing 33 is provided in the first seat 31 and is connected to the eccentric column 12. The limiting stage 32 is used to accommodate the test piece 100 and is configured to move vertically and horizontally when the eccentric column 12 drives the first bearing 33.

[0067] The vibration device provided in this application embodiment drives a rotating shaft to rotate via a drive assembly. An eccentric column extends parallel to the axial direction of the rotating shaft and is eccentrically connected to it. A first bearing in the first seat on the platform is connected to the eccentric column and moves with it. A limiting platform on the platform is connected to the first seat, thus allowing vertical and horizontal movement when the eccentric column drives the first bearing. This enables the test piece placed on the platform to realistically simulate vibrations during transportation. Compared to vehicle dynamic detection methods in related technologies, the vibration device in this application embodiment has a simple structure, convenient operation, and high detection efficiency.

[0068] In this embodiment, the eccentric column 12 refers to a column whose axis is parallel to but does not coincide with the axis of the rotation shaft 11. For example, the eccentric column 12 can be a cylinder. The vertical and horizontal movement refers to the position of the limiting platform 32 mounted on the first base 31 changing vertically and horizontally as it moves with the first bearing 33. Because the first bearing 33 is connected to the eccentric column 12, relative rotation is possible between them. Therefore, the eccentric column 12 itself cannot drive the first base 31 to rotate. However, the eccentric column 12 needs to rotate around the axis of the rotation shaft 11. At this time, when the eccentric column 12 rotates around the rotation shaft 11, the first base 31 will move along the same trajectory as the eccentric column 12. Because the first seat 31 is connected to the limiting platform 32, the limiting platform 32 can also move along the same trajectory as the first seat 31. For example, the movement trajectory of a certain point of the limiting platform 32 can be a circle.

[0069] In this embodiment of the application, the rotating shaft 11 is connected to the driving component 2, and the rotation speed of the rotating shaft 11 can be controlled by the driving component 2.

[0070] In some embodiments, the two ends of the stage 3 can be connected to different transmission components 1, and the different transmission components 1 can be driven by different drive components 2, that is, the different drive components 2 can operate asynchronously. For example, the different drive components 2 are two asynchronous motors. The transmission component 1 may include two rotating shafts 11, each equipped with an eccentric column 12. The two rotating shafts 11 do not interfere with each other and are driven by two asynchronous motors. The eccentric columns 12 on the two different rotating shafts 11 are respectively connected to the first base 31 on the stage 3, thereby enabling vertical and horizontal movement of both sides of the stage 3.

[0071] Furthermore, the first seat 31 and the limiting platform 32 can be connected by an elastic element. This elastic element allows different parts on the limiting platform 32 to move asynchronously or trace different trajectories when the two rotating shafts 11 rotate in different directions, angles, and speeds. For example, when a point on the left side of the limiting platform 32 is at its highest point, a point on the right side of the limiting platform 32 is at its lowest point; or the movement trajectories of a point on both the left and right sides of the limiting platform 32 are circular, but the circumferences of the two circles are not equal.

[0072] In addition, the movement trajectory of the stage 3 can be controlled by controlling the rotation speed of the motor. Therefore, the movement trajectory of the stage 3 can be complex and varied, and can realistically simulate the vibration of the test piece 100 during transportation.

[0073] In other embodiments, the transmission assembly 1 may include two rotating shafts 11, which can be driven by the same motor. The eccentric columns 12 on the two non-interfering rotating shafts 11 move asynchronously; for example, when the eccentric column 12 on rotating shaft A is at its highest point, the eccentric column 12 on rotating shaft B is at its lowest point. Furthermore, the first seat 31 and the limiting platform 32 are connected by an elastic element.

[0074] In some embodiments, such as Figure 6 and Figure 7 As shown, an eccentric column 12 can be provided at both ends of the rotating shaft 11.

[0075] In the embodiments of this application, such as Figure 8 As shown, when both ends of the rotating shaft 11 are provided with eccentric columns 12, and the eccentric columns 12 at both ends are in symmetrical positions at both ends of the rotating shaft 11 (symmetrical position means that the eccentric columns 12 are in the same position connected to the rotating shaft 11 in the plane perpendicular to the axis at both ends of the rotating shaft 11; or the two eccentric columns 12 on both sides can coincide when extended in opposite directions), the eccentric columns 12 at both ends of the rotating shaft 11 rotate synchronously. Therefore, when the limiting platform 32 moves with the eccentric columns 12, the movement trajectories on both sides of the limiting platform 32 are the same.

[0076] In some embodiments, Figure 9 As shown, the eccentric columns 12 corresponding to both ends of the rotation shaft 11 may be asymmetrically positioned at both ends of the rotation shaft 11. In this case, the rotation trajectories of the limiting platform 32 and the corresponding sides of the rotation shaft 11 are different. In some other embodiments, the first seat 31 and the limiting platform 32 are connected by an elastic element.

[0077] In some embodiments, Figure 10As shown, the eccentric pillars 12 distributed at both ends of the rotation shaft 11 are axially symmetrical at their positions at both ends of the rotation shaft 11, but the sizes of the eccentric pillars 12 at both ends are different (that is, the contact areas between the eccentric pillars 12 at both ends and the rotation shaft 11 are different). In this case, the rotation trajectories of the limiting platform 32 and the corresponding sides of the rotation shaft 11 are different. In some other embodiments, the first seat 31 and the limiting platform 32 are connected by an elastic element.

[0078] In some embodiments, the rotating shaft 11 has an eccentric column 12 at only one end, while the other end does not have an eccentric column 12. In this case, the movement trajectories of the limiting platform 32 and the corresponding two sides of the rotating shaft 11 are not the same. In addition, the first seat 31 and the limiting platform 32 are connected by an elastic element.

[0079] In some embodiments, such as Figure 5 As shown, the transmission assembly 1 may further include a transmission wheel 13; the transmission wheel 13 may be connected to the end of the rotating shaft 11 along the axial direction of the rotating shaft 11; the eccentric column 12 may be connected to the side of the transmission wheel 13 away from the rotating shaft 11.

[0080] In this embodiment, the transmission wheel 13 can be a regular cylinder or an irregular structure. For example, the transmission wheel 13 can be a cylinder with two through-bodies, or a cam with two through-bodies. The eccentric column 12 is connected to the side wall of the transmission wheel 13, and the eccentric column 12 does not interfere with the rotating shaft 11. Alternatively, the transmission wheel 13 can be a cylinder with one open side, the cylinder being fitted onto the end of the rotating shaft 11 through the opening, and the eccentric column 12 is connected to the side opposite to the opening of the cylinder. Still another option is that the transmission wheel 13 can be a cam with one open side, the cam being fitted onto the end of the rotating shaft 11 through the opening, and the eccentric column 12 is connected to the side opposite to the opening of the cam.

[0081] In this embodiment, the method of connecting the eccentric column 12 to the transmission wheel 13 and then to the rotating shaft 11 via the transmission wheel 13 is easier to implement than the method of directly connecting the eccentric column 12 to the rotating shaft 11. This is because the eccentric column 12 and the transmission wheel 13 are lighter, easier to process, and have lower costs.

[0082] In some embodiments, such as Figure 5 , Figure 6 and Figure 7 As shown, the rotating shaft 11 is concentrically inserted into the center of the transmission wheel 13, and the connection between the transmission wheel 13 and the rotating shaft 11 does not coincide with the center of the eccentric column 12.

[0083] In this embodiment, the transmission wheel 13 and the rotating shaft 11 can be coaxially arranged. For example, the transmission wheel 13 can be a cylinder concentrically arranged with the rotating shaft 11, or it can be a cam coaxially arranged. The center point of the connection between the transmission wheel 13 and the rotating shaft 11 does not coincide with the center point of the eccentric column 12; in other words, the center point of the eccentric column 12 is not on the axis of the rotating shaft 11.

[0084] In some embodiments, such as Figure 5 and Figure 6 As shown, the transmission assembly 1 may further include at least one transmission shaft 14, at least one first synchronous pulley 15, at least one second synchronous pulley 16, and at least one first synchronous belt 17; the transmission shaft 14 may be arranged in the same direction as the rotating shaft 11, and both ends of the transmission shaft 14 may be connected to the platform 3 respectively; the first synchronous pulley 15 and the second synchronous pulley 16 may be respectively arranged at corresponding positions of the rotating shaft 11 and the transmission shaft 14; the first synchronous belt 17 may be an annular belt, and the first synchronous belt 17 may be sleeved on the first synchronous pulley 15 and the second synchronous pulley 16; wherein, the first synchronous pulley 15 is configured to rotate with the rotating shaft 11 and drive the first synchronous belt 17 to rotate; the second synchronous pulley 16 is configured to rotate with the first synchronous belt 17, thereby driving the transmission shaft 14 to rotate.

[0085] In this embodiment, the drive shaft 14 can be correspondingly arranged with the rotating shaft 11. The rotating shaft 11 and the drive shaft 14 are respectively provided with corresponding first synchronous pulleys 15 and second synchronous pulleys 16, and the first synchronous pulleys 15 and 16 are connected by a first synchronous belt 17. When the rotating shaft 11 rotates, the first synchronous belt 17 rotates due to the friction between itself and the first synchronous pulley 15, thereby driving the second synchronous pulley 16 to rotate. Both ends of the rotating shaft 11 and the drive shaft 14 are connected to the platform 3. Therefore, when the eccentric column 12 on the rotating shaft 11 moves the corresponding position of the platform 3, the portion of the platform 3 corresponding to the drive shaft 14 can also move accordingly.

[0086] In some embodiments, the transmission assembly 1 may include a plurality of transmission shafts 14, which may be distributed on both sides or one side of the axial direction of the rotating shaft 11. When the plurality of transmission shafts 14 are distributed on both sides of the rotating shaft 11, for example, one transmission shaft 14 is provided on each side of the axial direction of the rotating shaft 11, the rotating shaft 11 corresponds to the middle position of the platform 3, and the two transmission shafts 14 are respectively located on the corresponding sides of the platform 3. Two first synchronous pulleys 15 may be provided on the rotating shaft 11, and two second synchronous pulleys 16 corresponding to the two first synchronous pulleys 15 on the rotating shaft 11 are respectively provided on the two transmission shafts 14. The first synchronous pulleys 15 and the second synchronous pulleys 16 are connected by a first synchronous belt 17.

[0087] When multiple drive shafts 14 are distributed on one side of the rotating shaft 11, for example, two drive shafts 14 are provided on the same side of the rotating shaft 11, and the two drive shafts 14 correspond to different positions of the platform 3 respectively; two second synchronous pulleys 16 are provided on the drive shaft 14 close to the rotating shaft 11; one of the second synchronous pulleys 16 is connected to the first synchronous pulley 15 on the rotating shaft 11 through the first synchronous belt 17, and the other second synchronous pulley 16 is connected to the second synchronous pulley 16 provided on the drive shaft 14 away from the rotating shaft 11 through the first synchronous belt 17. When the rotating shaft 11 drives the drive shaft 14 close to it to rotate, the drive shaft 14 away from it also rotates.

[0088] In some embodiments, such as Figure 5 and Figure 6 As shown, the transmission assembly 1 also includes a plurality of second seats 18; a second bearing 19 is provided inside the second seat 18, and the inner ring of the second bearing 19 is sleeved on the outer periphery of the rotating shaft 11 or the transmission shaft 14; the second seat 18 is used to position the rotating shaft 11 and the transmission shaft 14.

[0089] In this embodiment, the rotating shaft 11 and the transmission shaft 14 can be positioned by the second base 18. Because the second base 18 is provided with a second bearing 19, both the rotating shaft 11 and the transmission shaft 14 can rotate relative to the inner ring of the second bearing 19 connected to it, and the outer ring of the second bearing 19 is connected to the second base 18. Therefore, the rotating shaft 11 and the transmission shaft 14 can rotate at the position defined by the second base 18.

[0090] In some embodiments, such as Figure 5 and Figure 6 As shown, the transmission assembly 1 includes a rotating shaft 11 and a transmission shaft 14; a second seat 18 is provided at each end of the rotating shaft 11 and the transmission shaft 14; an eccentric column 12 is provided at the end of both the rotating shaft 11 and the transmission shaft 14, and the second seat 18 is located between the eccentric columns 12; a first synchronous wheel 15 is provided on the rotating shaft 11, and the first synchronous wheel 15 is located between the two second seats 18; a second synchronous wheel 16 corresponding to the first synchronous wheel 15 is provided on the transmission shaft 14.

[0091] In this embodiment, the rotating shaft 11 and the transmission shaft 14 are coaxially positioned via the second base 18; in other words, the rotating shaft 11 and the transmission shaft 14 are parallel. The rotating shaft 11 and the transmission shaft 14 are connected by a first synchronous belt 17. Furthermore, eccentric columns 12 are provided at both ends of the transmission shaft 14 and the rotating shaft 11. The eccentric columns 12 are located at the outermost ends of the two pairs of ends of the rotating shaft 11 and the transmission shaft 14, and are spaced apart from the second base 18. Therefore, when the eccentric columns 12 drive the stage 3 to move, they will not interfere with the second base 18, etc.

[0092] In some embodiments, drive wheels 13 may be provided at both ends of the rotating shaft 11 and the drive shaft 14. The drive wheels 13 are located between the second seat 18 and the eccentric column 12, and the drive wheels 13 are spaced apart from the second seat 18.

[0093] In some embodiments, in order to prevent the stage 3 or the test piece 100 placed on the stage 3 from colliding with any component on the transmission assembly 1 during the movement of the eccentric column 12, the distance between the stage 3 or the test piece 100 closest to the transmission assembly 1 and the transmission assembly 1 is at least greater than the distance between the positions of the eccentric column 12 when it rotates to the highest point and the lowest point (exemplarily, it can be the distance between the positions of the center points of the eccentric column 12 at the highest point and the lowest point).

[0094] In some embodiments, such as Figure 11 As shown, the stage 3 may include four first seats 31; two of the first seats 31 may be connected to the eccentric columns 12 at both ends of the rotating shaft 11 respectively, and the other two first seats 31 may be connected to the eccentric columns 12 at both ends of the transmission shaft 14 respectively.

[0095] In this embodiment, the stage 3 can be connected to the eccentric columns 12 at both ends of the rotating shaft 11 and the transmission shaft 14 via four first seats 31, so that the stage 3 can move under the drive of the eccentric columns 12.

[0096] In some embodiments, such as Figure 5 As shown, the vibration device may also include a support frame 4; the support frame 4 may be located on the side of the transmission assembly 1 away from the platform 3; the second seat 18 may be located on the side of the support frame 4 close to the platform 3 and connected to the support frame 4; the drive assembly 2 may be connected to the support frame 4.

[0097] In some embodiments, such as Figure 5 As shown, the support frame 4 may include a first support plate 41, a second support plate 42, and four support columns 43 arranged in pairs opposite to each other. The first support plate 41 may be located on the side of the second support plate 42 away from the rotation axis 11, and the first support plate 41 and the second support plate 42 may be spaced apart. The second base 18 may be fixed to the side of the second support plate 42 away from the first support plate 41. One end of the support column 43 may be connected to the second support plate 42, and the other end may be supported on the ground; the first support plate 41 may be connected between the two ends of the support column 43.

[0098] In some embodiments, such as Figure 5As shown, the drive assembly 2 may include a first drive wheel 21, a second drive wheel 22, a motor 23, and a second synchronous belt 24. The first drive wheel 21 can be connected to the rotating shaft 11, and the second drive wheel 22 can be connected to and driven by the motor 23. The first drive wheel 21 and the second drive wheel 22 are connected by the second synchronous belt 24. When the second drive wheel 22 is driven, it drives the second synchronous belt 24 to rotate, thereby driving the first drive wheel 21 to rotate, and consequently causing the rotating shaft 11 to rotate. The drive assembly 2 may also include a third seat 25, which can be used to position the second drive wheel 22.

[0099] In some embodiments, the motor 23 and the third base 25 may be fixedly mounted on the side of the first support plate 41 near the second support plate 42.

[0100] In some embodiments, such as Figure 12 As shown, the limiting platform 32 may include a first limiting part 321 and a second limiting part 322 correspondingly disposed at the two ends of the first base 31 on the side away from the transmission component 1; the first limiting part 321 and the second limiting part 322 may each have a plurality of first slots 3211 and a plurality of second slots 3221; the limiting platform 32 may also include at least two limiting rods 323; the test piece 100 may be clamped between the two limiting rods 323 respectively inserted into the first slot 3211 and the second slot 3221.

[0101] In this embodiment, two limiting rods 323 can be respectively secured in different first slots 3211 and different second slots 3221 of the first limiting part 321 and the second limiting part 322 to accommodate test pieces 100 of different sizes, thus securing them between the two limiting rods 323. When the size of the test piece 100 is small, the two limiting rods 323 can be adjusted in opposite directions; when the size of the test piece 100 is large, the two limiting rods 323 can be adjusted in opposite directions.

[0102] When the vibration equipment of this application is required to conduct a vibration test on the test piece 100, the test piece 100 is first placed on the limiting stage 32, and the position of the limiting rod 323 on the first limiting part 321 and the second limiting part 322 is adjusted according to the size of the test piece 100 to clamp the test piece 100. Then, the drive assembly 2 is started to drive the transmission assembly 1 to rotate, thereby driving the platform 3 to move, thus simulating the vibration of the test piece 100 on the platform 3 during transportation.
