[0038] The present invention provides a convertible handle durability testing device, please refer to Figure 1 The convertible handle durability testing device includes a bracket 40, a stretching component 20, a rotating component 30, a clamping component 10 and a controller, wherein the stretching component 20 is arranged on the bracket 40; the rotating component 30 is arranged on the stretching component 20; the clamping component 10 is arranged on the rotating component 30; the controller is electrically connected to the stretching component 20, the rotating component 30 and the clamping component 10 respectively, and the controller is used to sequentially send a clamping signal to the clamping component 10, send a stretching signal to the stretching component 20, and send a rotation signal to the rotating component 30; when the clamping component 10 receives the clamping signal, it clamps the convertible handle 60; when the stretching component 20 receives the stretching signal, it stretches the convertible handle 60; when the rotating component 30 receives the rotation signal, it rotates the convertible handle 60.

[0039] The bracket 40 can be arranged in the vehicle body 70 to serve as a supporting structure of the convertible handle durability test device. The bracket 40 can be arranged below the convertible handle 60, wherein the controller can also be electrically connected to the vehicle convertible 80 to control the opening and closing of the convertible 80. When performing the test, the controller first controls the convertible 80 to be closed. The controller sends corresponding control signals to control the stretching assembly 20, the rotating assembly 30 and the clamping assembly 10 to perform corresponding operations.

[0040] Specifically, the controller first sends a clamping signal to the clamping assembly 10, which includes a fixing plate 11, a clamping cylinder 13 and two clamping plates 12. The fixing plate 11 is arranged at the bottom of the hood handle 60; the two clamping plates 12 are arranged on the fixing plate 11, and the two clamping plates 12 are arranged on both sides of the hood handle 60; the clamping cylinder 13 is connected to the clamping plate 12, and the clamping cylinder 13 drives the two clamping plates 12 to move toward each other to clamp the hood handle 60, or drives the two clamping plates 12 to move away from each other to release the hood handle 60. The controller is electrically connected to the clamping cylinder 13, and when the clamping cylinder 13 receives the clamping signal, it drives the two clamping plates 12 to move toward each other, thereby clamping the hood handle 60 located in the middle. In order to simplify the structure, in this embodiment, one clamping cylinder 13 may be provided, connected to one of the clamping plates 12, and the other clamping plate 12 is fixed on the fixing plate 11 and abuts against the convertible handle 60. Thus, the clamping cylinder 13 drives one of the clamping plates 12 to move, so that the two clamping plates 12 can move toward and away from each other.

[0041] After the clamping assembly 10 clamps the convertible handle 60, the controller sends the stretching signal to the stretching assembly 20. The stretching assembly 20 includes a support frame 21 and a stretching cylinder 22. The support frame 21 is arranged on the bracket 40, and the rotating assembly 30 is arranged on the support frame 21; the stretching cylinder 22 is connected to the support frame 21, and the stretching cylinder 22 drives the support frame 21 to move to drive the rotating assembly to move up and down. The rotating assembly 30 and the clamping are both arranged on the support frame 21. The controller is electrically connected to the stretching cylinder 22, so that after the stretching cylinder 22 receives the stretching signal, it can drive the rotating assembly 30 and the clamping assembly 10 to move synchronously by directly driving the support frame 21 to move up and down, thereby further simplifying the structure. The stretching force of the stretching cylinder 22 is 55N to 65N.

[0042] When the hood handle 60 is stretched, the hood handle 60 can be rotated to achieve locking and unlocking operations. That is, the controller continues to send the rotation signal to the rotation assembly 30, and the rotation assembly 30 includes a rotation stepper motor 31. The rotation stepper motor 31 is disposed on the stretching assembly 20, and the fixing plate 11 is disposed on the rotation stepper motor 31. In this embodiment, the torque of the rotation stepper motor 31 is set at about 12N / M, so that the hood handle 60 can be driven to rotate.

[0043] It should be noted that the controller controls the rotating assembly 30 to rotate in a clockwise direction to achieve the locking operation of the convertible handle 60, and then controls the rotating assembly 30 to rotate in a counterclockwise direction to achieve the unlocking operation of the convertible handle 60. By repeating the above steps, the durability test of the convertible handle 60 is achieved. After the test is completed, the controller controls the clamping assembly 10, the stretching assembly 20 and the rotating assembly 30 to reset, so as to prepare for the durability test of the next convertible handle 80.

[0044] The technical solution of the present invention sequentially controls the grabbing assembly to grab the convertible handle 60 through the controller, pulls the convertible handle 60 through the stretching assembly 20, and finally rotates the convertible handle 60 through the rotating assembly 30 to realize the simulated operation of the convertible handle 60, thereby realizing automated simulated operation, being able to perform more simulated data collection, and being able to realize simulated operation in various harsh environments.

[0045] Furthermore, the convertible handle durability testing device further includes a buffer 50, which is disposed between the bracket 40 and the stretching assembly 20. The buffer 50 can be made of a flexible material, so as to buffer the impact force caused by the bracket 40 during the mechanical operation of the stretching assembly 20, the rotating assembly 30 and the clamping assembly 10, thereby ensuring the stability of the installation of the bracket 40.

[0046] Specifically, a flange 14 extends from the top of one of the clamping plates 12 toward one side of the other clamping plate 12. In this embodiment, the convertible handle 60 is a circular or elliptical ring structure, so in this embodiment, the height of the flange 14 can be set at a hollow position of the ring structure, so that when the two clamping plates 12 move toward each other, the flange 14 can extend into the convertible handle 60. When the stretching assembly 20 is lowered, the flange 14 abuts against the convertible handle 60, thereby improving the stability of the connection between the grabbing assembly and the convertible handle 60 during the stretching process.

[0047] The side walls of the fixed plate 11 are provided with slide grooves 111, and the two ends of the clamping plate 12 are provided with protruding sliders 121, and the sliders 121 are clamped in the slide grooves 111. The side walls of the fixed plate 11 on both sides are recessed inward to form the slide grooves 111, and the slide grooves 111 can be arranged in an arc surface. Correspondingly, the two ends of the clamping plate 12 extend outward, and the sliders 121 are formed on one side facing the slide grooves 111. The structure of the sliders 121 is adapted to the slide grooves 111, so that the clamping cylinder 13 can push the clamping plate 12 to slide on the fixed plate 11.

[0048] Specifically, the rotating assembly 30 further includes a detection member, which is arranged on the convertible handle 60 to detect angle information. The detection member is electrically connected to the controller. The controller is also used to determine the in-position state of the rotating stepping motor 31 according to the angle information, and control the start and stop of the rotating stepping motor 31 according to the in-position state. The in-position state includes locked in position and unlocked in position; the controller is also used to determine that the rotating stepping motor 31 is locked in position when the angle information is a first preset angle, and control the rotating stepping motor 31 to stop rotating; when the angle information is a second preset angle, the controller determines that the rotating stepping motor 31 is unlocked in position, and controls the rotating stepping motor 31 to stop rotating. In this embodiment, the first preset angle can be set to 135 degrees, and the second preset angle can be set to -135 degrees, so that the in-position state of the rotating stepping motor 31 can be determined according to the angle information. When the in-position state is the unlocked position, it means that the convertible handle durability testing device simulates the completion of the unlocking operation of the convertible handle 60 . When the in-position state is the locked position, it means that the convertible handle durability testing device simulates the completion of the locking operation of the convertible handle 60 .

[0049] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
