The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0019] First Embodiment:

[0021] The present utility model provides a performance detection device for an automotive exterior handle, which includes a frame 101, a fixing structure 102, and a detection component 103. The detection component 103 includes a lifting plate 104, a base 105, a tension sensor 106, a force measuring rod 107, a driving member 108, and a distance detection member 109. The distance detection member 109 includes a bracket 110 and a laser distance measurer 111. The driving member 108 drives the force measuring rod 107 to move, enabling the force measuring rod 107 to pull open the handle of the automotive exterior handle 115. At this time, the tension sensor 106 detects the force when pulling open the handle, and at the same time, the distance detection member 109 detects the positions of the handle before and after being pulled open, thereby obtaining the handle stroke. It can be understood that the foregoing solution can be used to improve the detection efficiency of the automotive exterior handle 115 and reduce costs. When the lifting plate 104 is driven to move in any direction, it can also be used.

[0022] For this specific embodiment, the fixing structure 102 is arranged on the frame 101. The fixing structure 102 can fix the automotive exterior handle 115, thereby improving the stability of the automotive exterior handle 115 during detection. The fixing structure 102 is a prior art, and its structure can be designed according to different automotive exterior handles 115, and will not be elaborated here.

[0023] Among them, the driving member 108 is arranged on the frame 101. The lifting plate 104 is connected to the frame 101 through the driving member 108. The base 105 is fixedly connected to the lifting plate 104 and is arranged on the lifting plate 104. The tension sensor 106 is fixedly connected to the base 105 and is located on one side of the base 105. The force measuring rod 107 is connected to the tension sensor 106 and is slidably connected to the base 105, and is located on the side of the tension sensor 106 away from the base 105. The distance detection member 109 is arranged on the frame 101; the laser distance measurer 111 is installed through the bracket 110, and the laser distance measurer 111 measures the distances between the handle before and after being pulled open and the laser distance measurer 111. The distance after the handle is pulled open minus the distance before the handle is pulled open is the stroke of the handle.

[0024] When using the performance detection device for the exterior door handle of an automobile according to this embodiment, the exterior door handle 115 of the automobile is fixed by the fixing structure 102, and then the initial distance between the laser distance measuring instrument 111 and the handle is measured. Then, the lifting plate 104 is driven to move by the driving member 108, thereby driving the base 105, the tension sensor 106, and the force measuring rod 107 to move, so that the force measuring rod 107 extends into the inner side of the handle and pulls the handle open. At this time, the tension sensor 106 can detect the force for pulling the handle open. At the same time, the laser distance measuring instrument 111 measures the distance between the laser distance measuring instrument 111 and the handle after the handle is pulled open. Subtracting the distance between the laser distance measuring instrument 111 and the handle when the handle is not pulled open from the distance after the handle is pulled open, the stroke of the handle can be obtained, thereby achieving the purpose of detecting the stroke and the tension simultaneously.
