[0017] For ease of understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.

[0018] See Figures 1-3 The shown LED lamp vibration test device includes a base 10, a driving part 20, a vibration part 30 and a working part 40. The base 10 mounts the entire device on the ground or a suitable workbench. The driving part 20 is connected to the vibration part 30, and the vibration part 30 is connected to the working part 40.

[0019] The base 10 includes a bottom plate 11, a rear column 12 and a front column 13. The rear end of the bottom plate 11 has a rear column 12, and the top of the rear column 12 has a clamp. A power source 21 is mounted on the clamp. The power source 21 can be a suitable power form such as a motor or an internal combustion engine. The front end of the bottom plate 11 has a front column 13, and the working part 40 is sleeved and mounted on the front column 13 to play a guiding role for the working part 40.

[0020] It should be added here that the structure of the clamp can be a form of upper and lower covering installation. The main purpose of the clamp is to stably mount the power source 21 on the rear column 12.

[0021] The driving part 20 includes a power source 21, a coupling 22, a transmission cylinder 23, a through hole 24, a screw rod 25 and a pin 26. The output shaft of the power source 21 is connected to the coupling 22, the coupling 22 is connected to the transmission cylinder 23, the transmission cylinder 23 is connected forward to the vibration part 30. The front end of the transmission cylinder 23 is hollowed out (not visible in the drawing due to the orientation). The side wall of the transmission cylinder 23 has a through hole 24 that penetrates up and down. The screw rod 25 is inserted into the through hole 24, and the bottom of the screw rod 25 is limited on the diameter line of the transmission cylinder 23 by the pin 26.

[0022] The shaking part 30 includes a conical cylinder 31, a bushing 32, sliding plates 33, a transition cylinder 34, a limit pin 35 and a rocker 36. The rear end of the conical cylinder 31 is a conical head 311 in a conical shape. The conical head 311 is sleeved in the front-end hollow structure of the transmission cylinder 23. The end face of the conical head 311 has a cross groove 312. A pair of sliding plates 33 are transversely sleeved in the cross groove 312, and a bushing 32 is longitudinally sleeved in the cross groove 312. Each of the two lateral sides of the bushing 32 has a sleeve rod 321. The sleeve rod 312 is sleeved and installed in the sliding plate 33. The inner hole of the bushing 32 has threads, and the screw rod 25 is screwed with the bushing 32. Rotating the screw rod 25 can jointly adjust the installation angle of the conical cylinder 31 in the transmission cylinder 23 through the bushing 32 and the sliding plates 33. The rear-end side wall of the conical cylinder 31 has a threaded hole 313. The rear end face of the conical cylinder 31 is a hollow structure (invisible in the attached drawing due to the orientation). The transition cylinder 34 is sleeved in the hollow structure at the rear end of the conical cylinder 31. The side wall of the transition cylinder 34 has a limit groove 341. The limit pin 35 is installed in the threaded hole 313, and the front end of the limit pin 35 is embedded in the limit groove 341 to limit the transition cylinder 34. The rocker 36 is sleeved and installed in the transition cylinder 34. The upper end of the rocker 36 has a sliding shaft 361, and the sliding shaft 361 is sleeved in the transition cylinder 34. The bottom of the rocker 36 has a ball head 362, and the ball head 362 is hinged to the working part 40.

[0023] It should be supplemented and explained here that the transverse and longitudinal directions of the cross groove 312 will change with the rotation of the conical cylinder 31. In this embodiment, the direction where the screw rod 25 is located is defined as the longitudinal direction, and the direction perpendicular to it is defined as the transverse direction. Furthermore, the sleeved installation of the rocker 36 in the transition cylinder 34 also needs to be limited, and this limiting structure can adopt a limiting structure similar to the pin 26 at the bottom of the screw rod 25, which is easy to implement for those skilled in the art.

[0024] The working part 40 includes a left hemisphere 41, a right hemisphere 42, a connecting rod 43 and a mounting plate 44. The left hemisphere 41 and the right hemisphere 42 are assembled and installed with each other, and the ball head 362 is sleeved therein. Each of the two sides of the left hemisphere 41 has an ear piece 411. The top of the left hemisphere 41 has a notch 412, and the notch 412 passes through the rod head of the ball head 362. The structure of the right hemisphere 42 is the same as that of the left hemisphere 41. The front end of the right hemisphere 42 is connected to the connecting rod 43. The connecting rod 43 passes through the top of the front column 13, and the connecting rod 43 is connected to the mounting plate 44. An LED lamp is placed on the mounting plate 44 for shaking test.

[0025] It should be noted here that for the convenience of display and description, the right hemisphere 42, the connecting rod 43 and the mounting plate 44 of this embodiment are of an integral structure. In an actual device, in order to achieve assembly, this component needs to be disassembled into multiple parts for separate production and then assembled and fitted, which is easily achievable by those skilled in the art. For the convenience of display and description, the mounting plate 44 of this embodiment is of a flat plate structure. In an actual device, the structure of the mounting plate 44 should be specifically designed according to the structure of the LED lamp. For example, evenly arranged grooves are formed on the mounting plate 44 to place the lamp.

[0026] The working principle of the present invention is as follows: The power source 21 drives the transmission cylinder 23 to rotate through the coupling 22. The transmission cylinder 23 drives the conical cylinder 31 to rotate through the screw 25, the bushing 32 and the sliding piece 33. At this time, it should be noted that when the screw 25, the bushing 32 and the sliding piece 33 are all in the middle position, the rotation of the conical cylinder 31 cannot drive the rocker 36 to rotate. By adjusting the screw 25, the rotation of the screw 25 drives the bushing 32 to move up and down, and at the same time the sliding piece 33 makes an adaptive movement, jointly pushing the conical cylinder 31 to adjust the angle. The transition cylinder 34 and the rocker 36 rotate accordingly, and motion compensation is carried out through the rotation of the ball head 362 and the sliding of the connecting rod 43. After the conical cylinder 31 deflects a certain angle, the rotation of the conical cylinder 31 can drive the rocker 36 to make a swinging motion through the transition cylinder 34. The swinging motion of the rocker 36 is transmitted through the combination of the ball head 362, the left hemisphere 41 and the right hemisphere 42 and under the guiding action of the front column 13. The mounting plate 44 makes a reciprocating motion back and forth along with the connecting rod 43 and swings left and right around the connecting rod 43. The combination of these two motions forms the shaking vibration motion of the mounting plate 44, and the LED lamp placed thereon is subjected to a shaking vibration test. By adjusting the screw 25, the appropriate shaking vibration frequency and amplitude can be obtained.

[0027] The above embodiments mainly illustrate the LED lamp shaking vibration test device of the present invention. Although only a limited number of embodiments and technical features are described, those skilled in the art should understand that the present invention can be implemented in many other forms without departing from its gist and scope. Therefore, the embodiments shown are regarded as illustrative rather than restrictive. Without departing from the spirit and scope of the present invention defined by the appended claims, the present invention may cover various modification and replacement schemes.
